"Papilarni karcinomi štitaste žlezde (PTC) predstavljaju najučestalije karcinome endokrinog porekla. Poslednjih decenija, incidenca ovih karcinoma je u stalnom porastu zbog čega je identifikacija molekularnih markera koji bi doprineli preciznijoj klasifikaciji bolesnika sa rizikom za progresiju bolesti, a u cilju izbora terapijskog pristupa, od izuzetnog kliničkog značaja. Gen VHL uključen je u tumorigenezu različitih tipova karcinoma i u mnogima od njih je povezan sa agresivnijim biološkim ponašanjem. Uloga i značaj VHL u patogenezi i progresiji PTC do sada nisu ispitivani. Predmet ove studije bio je ispitivanje nivoa ekspresije VHL u PTC. Ekspresioni profili VHL iRNK i proteina određeni su metodama PCR u realnom vremenu i imunohistohemijom. Istovremeno, ispitano je da li su mutacioni događaji u kodirajućoj sekvenci gena i regulacija koja se odvija na post-transkripcionom nivou a posredovana je miR-92a, odgovorni za detektovane različite nivoe ekspresije VHL. Sekvenciranjem sva tri egzona gena VHL nisu detektovane mutacione promene. Nivo ekspresije miR- 92a, iako izmenjen, nije značajno korelisao sa nivoima ekspresije VHL iRNK i proteina. Ovi rezultati ukazuju na to da su za promene u ekspresiji VHL verovatno odgovorni neki drugi regulatorni mehanizmi. U odnosu na nivo ekspresije VHL iRNK u PTC i odgovarajućem neizmenjenom tireoidnom tkivu, utvrđeno je da postoje dve grupe bolesnika – oni sa sniženom i oni sa povišenom ekspresijom VHL u tumorskom tkivu. Detektovane promene ekspresionog profila VHL u korelaciji su sa kliničkim i patohistološkim parametrima PTC. Takođe, utvrđeno je da je niska ekspresija VHL iRNK povezana sa kliničkim i patohistološkim karakteristikama koje ukazuju na agresivnije ponašanje tumora, kao i da je povezana sa kraćim trajanjem vremenskog perioda bez znakova bolesti. Rezultati ove studije sugerišu da bi evaluacija ekspresije VHL tumorskog supresora mogla imati klinički značaj u prognozi agresivnijeg toka bolesti kod bolesnika sa PTC."

"Papillary thyroid carcinomas (PTC) represent the most prevalent type of endocrine malignancy. Over the last decades their incidence has been increasing, underlining the significance of the identification of molecular markers which would improve the risk stratification and help optimize the therapeutic approach to PTC patients. While the VHL gene is implicated in tumorigenesis of different types of carcinoma and has been reported to be associated with more aggressive biological behavior, its importance in the patogenesis and progression of PTC has not been explored so far. The subject of this study was to investigate the expression level of VHL in this type of carcinoma. The expression profiles of VHL mRNA and protein were determined using real time PCR and immunohistochemistry. In addition, it was investigated whether mutations in the coding sequence and post-transcriptional expression regulation mediated with miR-92a were responsible for VHL expression alterations detected in this study. No mutations were detected by sequencing of all three exons of the VHL gene. The expression level of miR-92a, although altered, did not show significant correlation with VHL mRNA and protein levels. These results suggest that probably some other regulatory mechanisms are responsible for VHL expression alterations. The analysis of VHL mRNA expression levels in PTC tissues compared to matched non-tumour tissues revealed that there were two groups of patients – patients with a decreased VHL expression level and patients with an increased expression level in tumour tissue. The detected VHL expression profile alterations were in correlation with PTC clinicopathological parameters. Moreover, low VHL expression was associated with more aggressive tumour features and with a shorter disease free interval. The results of this study suggest that evaluation of VHL tumor suppressor expression level might have significance in the prognosis of more aggressive course of the disease in PTC patients."

"Rod Campanula je u flori Evrope zastupljen sa više od 250 vrsta i podvrsta, od kojih je oko 90 zabilježeno za Balkansko poluostrvo, a oko 60 je endemično za dati region. Rod Campanula na Balkanskom poluostrvu karakteriše značajni morfološki diverzitet, koji je naročito naglašen u određenim grupama i kompleksima. Balkansko poluostrvo kao jedan od refugijalnih centara evropske flore karakteriše i značajan broj kriptičnih vrsta ili pak onih koje su uključene u sinonimiku šire rasprostranjnih vrsta. Upravo iz ovih razloga, rod Campanula je jedan od najinteresantnijih istraživačima flore Balkana i specijalistima za dati rod. U morfološke i molekularne analize uključeni su sljedeći predstavnici roda Campanula sa glavičastim cvastima: C. lingulata Waldst. & Kit., C. glomerata L., C. trautvetteri Grossh. ex Fed., C. cervicaria L., C. foliosa Ten., C. moesiaca Velen., C. pangea Hartvig i C. tymphaea Hausskn. Takođe, u molekularne analize je uključena i jedna specifična populacija sa serpentinita u okolini Skadarskog jezera u Albaniji, koji smo privizorno vodili kao poseban takson sa neformalnim imenom „C. pseudoradicosa“. Komparativna morfološka analiza je urađena na ukupno 1555 jedinki iz 53 populacije sljedećih glavičastih predstavnika roda Campanula: C. lingulata (402 jedinke iz 14 populacija), C. glomerata (669 jedinki iz 22 populacije), C. cervicaria (221 jedinka iz osam populacija), C. foliosa (127 jedniki iz četiri populacije), C. moesiaca (76 jedinki iz tri populacije), C. pangea (30 jedinki iz jedne populacije) i C. tymphaea (30 jedinki iz jedne populacije). Analizirano je ukupno 60 morfometrijskih i merističkih karaktera na cijelom uzorku, a broj karaktera je zavisio od vrste. Molekularne analize su urađene korišćenjem dva plastidna intergenska spejsera, trnGUCC-trnSGCU i psbA-trnH, na dva seta podataka. U prvom setu je urađena filogenija i filogeografija studiranih glavičastih predstavnika roda Campanula na centralnom dijelu Balkanskog poluostrva, dok je u drugom setu urađena filogenija i utvrđivanje vremenskih okvira divergencije klada kompleksa C. lingulata. Prvi set filogenetskih i filogeografskih analiza je urađen na ukupno 124 jedinke i to: C. lingulata (75 jedinki iz 17 populacija koje adekvatno predstavljaju diverzitet ovog kompleksa koji je detaljno obrađen u drugom setu filogeteskih analiza), C. glomerata (22 jedinke iz 19 populacija), C. cervicaria (sedam jedinki iz sedam populacija),C. foliosa (sedam jedinki iz šest populacija), C. moesiaca (tri jedinke iz tri populacije), C. divergens (6 jedinki iz dvije populacije), dok je za vrste C. tymphaea, C. pseudoradicosa, C. trautvetteri i E. graminifolius uzeta po jedna jedinka..."

"Eksperimentalni autoimunski encefalomijelitis (EAE) je model multiple skleroze (MS), hronične inflamatorne bolesti centralnog nervnog sistema (CNS). Osnovne patogene populacije u EAE su efektorski T limfociti koji produkuju interferon-γ (Th1) ili interleukin-17 (Th17) i aktivirani makrofagi koji dovode do oštećenja CNS. Imajući u vidu da krastavac (Cucumis sativus) predstavlja bogat izvor sekundarnih metabolita kao što su polifenoli i kukurbitacini, u ovoj studiji je po prvi put ispitivano dejstvo različitih ekstrakata krastavca na encefalitogeni potencijal T limfocita, efektorske funkcije makrofaga i antigen-prezentujuću aktivnost dendritskih ćelija (DĆ). Rezultati su pokazali da ekstrakt lista krastavca (ELK) ostvaruje najpotentnije dejstvo, inhibirajući produkciju IFN-γ i IL-17 od strane encefalitogenih T limfocita, modulišući signalne puteve Nf-κB i p38 (MAPK). Pored toga, ELK je ostvario inhibitorno dejstvo na efektorske funkcije makrofaga i antigen-prezentujuću aktivnost DĆ u koncentracijama koje nisu pokazale citotoksičnost na embrione zebrice (Danio rerio) in vivo. Dalje, ELK je uspešno inhibirao encefalitogene T limfocite nakon in vivo primene u EAE. Kvantitativna i kvalitativna analiza ELK metodom masene spektrometrije potvrdila je prisustvo 37 različitih jedinjenja od kojih su kukurbitacini bili najzastupljenija jedinjenja. Shodno tome, ispitana su i imunomodulacijska dejstva kukurbitacina B i kukurbitacina E na glavnim imunskim ćelijama uključenim u patogenezu EAE. Ova ispitivanja su potvrdila dejstva ELK, sugerišući da su kukurbitacini, kao glavni konstituenti ovog ekstrakta, barem delimično odgovorni za ostvarena dejstva ELK. Rezultati ove doktorske disertacije ukazuju na to da ekstrakt lista krastavca i kukurbitacini ostvaruju snažne antiencefalitogene efekte u modelu EAE i ukazuju na važnost dodatnih istraživanja u cilju pronalaženja odgovarajućih tretmana autoimunosti CNS."

"Experimental autoimmune encephalomyelitis (EAE) is an animal model of multiple sclerosis (MS), a chronic inflammatory disease of the central nervous system (CNS). T lymphocytes, which produce interferon-γ (Th1) or interleukin-17 (Th17), and activated macrophages, that lead to CNS damage, are the major pathogenic cell populations in EAE. Having in mind that cucumber (Cucumis sativus) is a rich source of secondary metabolites such as polyphenols and cucurbitacins, in this study, for the first time, the effects of various cucumber extracts were investigated on encephalytogenic T lymphocytes, effector function of macrophages and antigen-presenting activities of dendritic cells (DC). The results show that cucumber leaf extract (CLE) expresses the most potent effect by inhibiting the production of IFN-γ and IL-17 in encephalytogenic T lymphocytes, through modulation of signaling pathways Nf-κB and p38 (MAPK). Additionally, CLE imposes an inhibitory effect on the effector functions of macrophages and antigen-presenting activity of DC in concentrations that do not show cytotoxicity in zebrafish (Danio rerio) in vivo. Also, CLE inhibits generation of encephalitogenic cells in vivo. Phytochemical analysis of CLE, characterized by mass spectrometry, confirmed the presence of 37 different compounds, among which cucurbitacins were the most abundant compounds. Hence, the immunomodulatory effects of cucurbitacin B and cucurbitacin E were also examined on the major immune cells involved in EAE pathogenesis. The obtained results confirm the effects of CLE, suggesting that cucurbitacins are, at least partially, responsible for its effects. The results of this doctoral dissertation indicate that the cucumber leaf extract and its major constituents cucurbitacins have anti-encephalitogenic effects in the EAE model, Moreover, they suggest the importance of additional research towards novel highly efficient CNS autoimmunity treatments."

"Uprkos razvoju imunoterapije i ciljanih terapija, globalna incidenca melanoma nastavlja da raste. Konvencionalna hemoterapija, naţalost, pokazuje ograniĉenu efikasnost u leĉenju metastatskog melanoma. Primenu najĉešće korišćenog hemoterapeutskog leka cisplatine, ograniĉava uroĊena rezistencija ovog tipa tumora, što sve naglašava potrebu za razvojem efikasnije hemoterapije melanoma. Progres u medicinskoj organometalnoj hemiji omogućio je racionalni dizajn novih, nekonvencionalnih platinskih kompleksa, kao i neplatinskih antitumorskih jedinjenja, ukljuĉujući organokalajna jedinjenja, ĉija aktivnost ne poĉiva na direktnoj interakciji sa DNK. MeĊutim, nedovoljna rastvorljivost i toksiĉnost organokalajnih jedinjenja ograniĉava kompleksnija istraţivanja i ulazak u kliniĉka ispitivanja. U tom kontekstu, primena nanotehnologije u svrhu povećanja rastvorljivosti lekova i njihove selektivnosti prema maligno transformisanim klonovima u hemoterapiji kancera ima vodeću ulogu. Inkapsulacija hidrofobnih antitumorskih lekova u mezoporozne nanomaterijale silike, predstavlja najperspektivniju strategiju u ovoj oblasti. Zbog visokog potencijala za adsorpciju, nosaĉ SBA-15 je najinteresantniji mezoporozni silikat za ciljanu isporuku lekova. U skladu sa tim, u ovoj studiji je po prvi put ispitivan antitumorski potencijal organokalajnog(IV) jedinjenja [Ph3Sn(CH2)6OH] skladištenog u mezoporozni materijal SBA-15 (SBA-15pSn) in vitro i in vivo u modelu mišjeg melanoma. Imajući u vidu izuzetnu heterogenost melanoma, ispitivan je i njihov uticaj na visoko invazivnu liniju humanog melanoma, A375. Analizirani su ćelijski i molekulski mehanizmi pokrenuti u odgovoru na tretman eksperimentalnim agensima u ćelijama melanoma, kao i mehanizam preuzimanja ĉestica SBA-15pSn u humane ćelije melanoma u sistemu in vitro. [Ph3Sn(CH2)6OH] u slobodnoj formi ali, mnogo potentnije, uskladišten u SBA-15 smanjio je vijabilitet ćelijskih linija melanoma poreklom od miša B16, i ĉoveka A375. Isti trend je zapaţen u singenom modelu mišjeg melanoma in vivo. Pokazalo se da A375 ćelije melanoma preuzimaju SBA-15pSn pasivnim putem i makropinocitozom."

"Despite rapid development in immunotherapy and targeted therapies, the global incidence of melanoma continues to increase. Besides, conventional chemotherapy demonstrates only limited efficacy in the treatment of advanced melanoma. Clinical application of widely used chemotherapeutic drug cisplatin, is hampered by the intrinsic resistance of this type of tumor, indicating the urgent need for the development of more effective chemotherapies for melanoma. The rapid progress in medicinal organometallic chemistry in the past few years allows rational design of novel platinum compounds, as well as nonplatinum metal-based antitumor agents, including organotin compounds, whose activity is not based on unrepairable interaction with DNA. Poor solubility and toxicity of organotin compounds, however, restrains more complex studies and further development in the preclinical and subsequently clinical setting. Nanotechnology now becomes an important part of pharmaceutical research and development, for improving the solubility and selective toxicity of cancer therapeutics. Encapsulating hydrophobic antitumor agents in ordered mesoporous silica nanomaterials is an emerging strategy to enhance drug dissolution. Due to its high drug loading capacity, SBA-15 is the most interesting mesoporous silicate for targeted drug delivery. Antitumor potential of organotin(IV) compound [Ph3Sn(CH2)6OH] grafted on nanostructured material SBA-15 (SBA-15pSn) in vitro and in vivo in the mouse model of melanoma, was tested for the first time in this study. Considering the enormous heterogeneity of this type of tumor, it was of interest to test these experimental therapeutics in a highly invasive human A375 melanoma cell line. Given the fact that SBA-15pSn nanoparticles are relatively large, the mechanism of cellular uptake was defined. At the molecular level, main intracellular events triggered by the treatment, as well as the expression of key signaling pathways mediating tumor cell response, were analyzed..."

"Sonic Hedgehog (SHH) signalni put ima važnu ulogu u procesima koji se odvijaju tokom embrionalnog razvića u kojima kontroliše proliferaciju i diferencijaciju ćelija i učestvuje u održavanju polarnosti tkiva. Poslednjih godina mnogobrojni literaturni podaci pokazuju da promena u regulaciji SHH signalnog puta dovodi do nastanka i progresije različitih vrsta tumora kod čoveka. SHH signalni put je povezan sa meduloblastomom, leukemijom, karcinomom bazalnih ćelija, tumorima pluća, prostate, pancreasa, dojke i jajnika. Takođe, povećana ekspresija komponenti SHH signalnog puta je primećena u premalignim lezijama i ćelijama karcinoma grlića materice. SOX18 gen pripada familiji SOX gena koji kodiraju transkripcione faktore uključene u kontrolu različitih procesa tokom embrionalnog razvića. SOX18 protein ima važnu ulogu u razviću vaskularnog sistema kao i u adultnoj neovaskularizaciji. Uloga SOX18 proteina u vaskularnom razviću otkrivena je na osnovu poremećaja u razvoju vaskularnog sistema koji su uočeni kod prirodnih mutanata miša i čoveka. Osim toga, kod adultnog organizma SOX18 protein učestvuje u regulaciji angiogeneze i limfangiogeneze kako u fiziološkim stanjima organizma, tako i tokom patofizioloških promena kao što su zarastanje rana i tumorska angiogeneza. Takođe, pokazano je da se inhibicijom SOX18 funkcije utiče na limfangiogenezu čime se sprečava metastaza ćelija tumora. Najnoviji podaci pokazuju da je ekspresija SOX18 gena, detektovana u ćelijama invazivnog karcinoma dojke i tumora jajnika, a nivo ekspresije je u direktnoj korelaciji sa stadijumom tumora i može predstavljati prognostički marker. Predmet istraživanja prikazanog u ovom radu je bila analiza uloge SHH signalnog puta u regulaciji ekspresije SOX18 gena u HeLa ćelijama, in vitro model sistemu karcinoma grlića materice. Prvo je analizirana uloga GLI regulatornih proteina, finalnih efektora SHH signalne kaskade, u regulaciji transkripcije SOX18 gena. Prikazani rezultati su pokazali da su GLI1 i GLI2 pozitivni regulatori promotorske aktivnosti SOX18 gena kao i da povećavaju endogenu ekspresiju SOX18 gena, dok GLI3 transkripcioni faktor nije uticao na aktivnost SOX18 promotorskog konstrukta niti na nivo endogene ekspresije SOX18 gena u HeLa ćelijama..."

"The Sonic Hedgehog (SHH) signaling pathway plays important role in embrionic development directing cell proliferation and diferentiation and maintaing tissue polarity. In adults, this signaling pathway is rather suppressed. SHH signaling pathway has been associated with medulloblastoma, leukemia, basal cell carcinoma and lung, prostate, pancreatic, breast and ovarian cancers. In the last years, numerous data show that deregulation of SHH signaling pathway has been associated with onset and progression of various types of human cancer. It was shown that increased expression of HH-signaling molecules was seen in precancerous lesions and in cervical cancer. SOX18 gene is a member of SOX gene family that encodes transcription factors implicated in the control of various developmental processes. SOX18 protein plays important roles in vascular development and postnatal neovascularization. The functional importance of SOX18 protein in vascular development is revealed by the vascular defects caused by mutation in mice and humans. Also, in adults SOX18 is involved in the regulation of angiogenesis and lymphangiogenesis in physiological and pathophysiological condition such in wound healing or tumor growth. Furthermore, it has been reported that interfere with SOX18 function impairs tumor lymphangiogenesis which decreases the rate of cancer cell metastasis. In past two years, literature data show SOX18 expression in invasive ductual breast carcinoma and ovarian carcinoma and that level of expression correlates with poor prognosis suggesting that a SOX18 expression may serve as a prognostic marker. The aim of this study was to investigate the role of Sonic Hedgehog signaling pathway in the regulation of SOX18 gene expression in HeLa cells, in vitro model system of cervical cancer . We were analyzing the effect of GLI regulator proteins, final effectors of SHH signaling pathway, on transcriptional regulation of SOX18 gene expression. Presented results have shown that GLI1 and GLI2 are potent activators of SOX18 promoter activity as well as SOX18 expression in HeLa cells, while GLI3 had no effect..."

"Sve pacijentkinje sa detektabilnom ekspresijom hormonskih receptora (HR) za karcinom dojke (KD) trebalo bi da se leče endokrinom terapijom (ET). Za premenopauzne pacijentkinje, tamoksifen i/ili ovarijalna supresija (OvS) su adekvatna terapija. Promene u fosfataza i tenzin homolog (PTEN) signalnom putu bi mogle da budu jedan od mogućih mehanizama rezistencije na antiestrogenu terapiju. Cilj ovog istraživanja je ispitivanje povezanosti ekspresije PTEN proteina sa prognostičkim faktorima [(histologija i gradus tumora, status receptora za estrogen (ER) i receptora za progesteron (PgR), status receptora za humani epidermalni faktor rasta (HER2)] i sa odgovorom na terapiju kod premenopauznih pacijentkinja sa HR pozitivnim ranim KD lečenih adjuvantnom ovarijalnom ablacijom (OA). Pacijenti i metode: Analizirali smo grupu premenopauznih pacijentkinja sa ranim (stadijum I/II) HR pozitivnim KD koji su lečeni radikalnom mastektomijom a zatim adjuvantnom terapijom u vidu OA. Sadržaji ER i PgR su određeni klasičnom biohemijskom metodom [engl. Classical biochemical dextrane-coated charcoal (DCC) method], HER2 status je određen hromogenom in situ hibridizacijom (CISH metoda) i PTEN status je određen imunohistohemijskom metodom (IHH). Rezultati: U ovu analizu je uključeno 66 premenopauznih pacijentkinja. Medijana praćenja je 17 godina (opseg 1-29 godina). U poređenju sa PTEN pozitivnim KD, PTEN negativni KD su bili značajno više povezani sa lobularnim histološkim tipovima tumora (p<0.05) i sa višim sadržajem ER (p<0.05). Pacijentkinje sa PTEN negativnim KD su imali značajno kraće preživljavanje bez progresije bolesti (DFS) (p<0.01) i ukupno preživljavanje (OS) (p<0.01) u poređenju sa pacijentkinjama sa PTEN pozitivnim KD. Zaključak: Naši rezultati mogu da znače da PTEN status određen kao ekspresija PTEN proteina može da razdvoji premenopauzne HR pozitivne pacijentkinje sa KD lečene OA, na podgrupe sa dobrom i lošom prognozom bolesti."

"All breast cancer (BC) patients with detectable hormone receptors (HR) expression should be offered endocrine therapy (ET). For premenopausal patients, tamoxifen and/or ovarian suppression (OvS)/ ablation (OA) may improve disease outcome. Alteration of phosphatase and tensin homolog (PTEN) signaling pathway could be one of possible mechanisms of resistance to antiestrogen therapy. The aim of this study was to investigate the association of PTEN protein expression with prognostic factors [tumor histology and grade, estrogen receptor (ER) and progesterone receptor (PgR) status, human epidermal growth factor receptor 2 (HER2) status] and disease outcome in premenopausal patients with HR-positive early BCs treated with adjuvant OA. Methods: We analyzed a group of premenopausal early (stages I/II) HR-pos BC patients who had undergone radical mastectomy followed with adjuvant OA by irradiation only. ER and PgR contents were determined by classical biochemical dextrane-coated charcoal (DCC) method, HER2 status by chromogen in situ hybridization (CISH) analysis and PTEN status by immunohistochemistry (IHC). Results: Sixty-six premenopausal patients included into this analysis were followed for a median of 17 years (range 1-29). Compared to PTEN-pos BCs, PTEN-neg BCs were significantly more frequently associated with lobular tumor histology (p<0.05) and a higher ER content (p<0.05). Patients with PTEN-neg BC had significantly decreased disease-free survival (DFS) and overall survival (OS) (p<0.01 for both) compared to patients with PTEN-pos BCs. Conclusions: It seems that PTEN status determined by protein expression may discriminate between subgroups with poor and good prognosis in premenopausal HR-pos BC patients receiving adjuvant OA."

"Depresija je visokoprevalentno, multifaktorijalno i heterogeno psihijatrijsko oboljenje kompleksne neurobiološke osnove. S obzirom da veliki broj pacijenata (30– 40%) ne postiže remisiju bolesti uprkos antidepresivnoj terapiji, patofiziologija depresije i mehanizmi delovanja antidepresiva i danas su aktuelne problematike iako se intenzivno istražuju decenijama unazad. Brojne studije ukazuju da hronični psihosocijalni stres, vodeći sredinski faktor rizika za razvoj depresije, izaziva oksidativni stres i inflamaciju u mozgu, procese koji imaju važnu ulogu u etiopatofiziologiji ovog oboljenja. Pored toga, sve je više podataka koji pokazuju da je disregulacija γ-aminobuterna kiselina (GABA) sistema u mozgu povezana sa depresijom. U radu su analizirani efekti antidepresiva fluoksetina i atipičnog antipsihotika klozapina na glutation (GSH)-zavisni antioksidativni sistem i parametre inflamacije u hipokampusu i prečeonoj zoni kore cerebruma, moždanim regionima posebno osetljivim na stres. Takođe, ispitan je uticaj ovih lekova na GABA signalizaciju u medijalnoj prečeonoj zoni kore cerebruma, kao i njihova hepatotoksičnost. Ovi efekti su istraživani na životinjskom modelu depresije koji se zasniva na hroničnom izlaganju psihosocijalnom stresoru. Odrasli mužjaci pacova Wistar soja su podvrgavani 21- dnevnoj izolaciji, a fluoksetin i klozapin su davani stresiranim pacovima tokom izolacije, kao i nestresiranim (kontrolnim) pacovima u periodu od 21 dana. Hronična izolacija je dovela do promena u ponašanju koje nalikuju depresivnom i anksioznom, kompromitovala antioksidativnu odbranu posredovanu glutation peroksidazom i izazvala porast nivoa faktora nekroze tumora α (TNF-α) u hipokampusu. Takođe, izolacija je uzrokovala smanjenje koncentracije GSH, aktivaciju nuklearnog faktora-κB i porast nivoa medijatora inflamacije ciklooksigenaze-2 (COX- 2), interleukina-1β i TNF-α u prečeonoj zoni kore cerebruma. Fluoksetin i klozapin su onemogućili razvoj promena u ponašanju i proinflamatorne procese u obe ispitivane moždane strukture kod izolovanih pacova. Što se tiče GSH-zavisnog sistema, fluoksetin je pokazao protektivni efekat ali samo u prečeonoj zoni kore cerebruma pacova..."

"Depression is a highly prevalent, multifactorial and heterogeneous disorder with complex neurobiology. Large numbers of patients (30–40%) do not achieve disease remission despite receiving antidepressive therapy. Thus, despite the decades of research, the pathophysiology of depression and mechanisms of antidepressants’ actions are ongoing and widespread issues. A growing body of evidence indicates that psychosocial stress, the leading environmental risk factor, causes oxidative stress and inflammation in the brain and that these processes have important role in the pathophysiology of depression. In addition, dysregulation of γ-aminobutyric acid (GABA)-ergic system is becoming increasingly associated with this disorder. In this study, we analyzed the effects of antidepressant fluoxetine and atypical antipsychotic clozapine on the glutathione (GSH)-dependent antioxidative system and parameters of inflammation in hippocampus and prefrontal cortex, brain regions particularly sensitive to stress. Besides, we examined the effects of drugs on the GABAergic signalization, as well as their hepatotoxicity. These effects were investigated in an animal model of depression based on chronic psychosocial stress. Adult male Wistar rats were isolated for 21 days and fluoxetine and clozapine were applied to the stressed rats during isolation, as well as to non-stressed rats for 21 days. Chronic isolation caused depressive- i anxiety-like behaviors, compromised glutathione peroxidase-mediated antioxidative defense and caused increase in tumor necrosis factor α (TNF-α) levels in hippocampus. Besides, isolation decreased GSH levels, activated nuclear factor-κB and elevated cyclooxygenase-2 (COX-2), interleukin-1β i TNF-α levels in prefrontal cortex. Fluoxetine and clozapine prevented behavioral changes and proinflammatory events in both examined brain structures in isolated rats. Regarding GSH-dependent defense, fluoxetine showed protective effects, which were restricted to the prefrontal cortex.

"Evropska tekunica (Spermophilus citellus, L. 1766) je endemična vrsta za područje Centralne i Jugoistočne Evrope. Recentni areal je karpatskim masivom podeljen na dva dela. Severni deo se karakteriše uniformnim stepskim staništima koja se javljaju na malim nadmorskim visinama, dok se južni deo areala nalazi na Balkanu, gde su prisutni različiti tipovi staništa sa različitim ekološkim uslovima i na različitim nadmorskim visinama. Najveći broj populacija na području Srbije nalazi se u njenom severnom delu, tj. Vojvodini, dok je svega nekoliko malih i izolovanih planinskih populacija prisutno u istočnom i jugoistočnom delu zemlje Tekunice naseljavaju isključivo stepska staništa, livade i pašnjake koji su obrasli niskom travom. Međutim, usled intenzivnog pretvaranja stepskih predela u poljoprivredno zemljište tokom proteklih nekoliko decenija, nestala su široka prostranstva na kojima je tekunica bila kontinuirano rasprostranjena. Danas vrsta opstaje samo na jako izolovanim stepsko-livadskim fragmentima koji su sačuvani unutar dominantnog poljoprivrednog matriksa. S obzirom da broj populacija konstantno opada na celom arealu i da je budući opstanak vrste doveden u opasnost, tekunica je od 2008. godine na IUCN Crvenoj listi ugroženih vrsta svrstana u kategoriji ranjiva (VU). Zakonski status tekunice u Evropi regulišu EU Direktiva o staništima (Aneks II i IV) i Konvencija o očuvanju evropske divlje flore i faune i prirodnih staništa, poznatija kao Bernska konvencija (Aneks II). Unutar mreže Natura 2000 do sada je u režim zaštite uključeno 414 staništa koja naseljava tekunica. Na nacionalnom nivou tekunica je zaštićena zakonom kao strogo zaštićena vrsta. U cilju analize genetičkog diverziteta i strukture populacija tekunice na teritoriji Srbije, u periodu 2007-2009. godine, prikupljeno je ukupno 180 uzoraka tkiva sa 11 lokaliteta (Krušedol, Neradin, Mala Remeta, Sremska Mitrovica, Banatska Palanka, Šušara, Mokrin, Lok i Tomislavci sa teritorije Vojvodine i po jedan lokalitet sa Vlasine i Stare planine). Procena gustine i brojnosti populacija tekunice vršena je u periodu 2004- 2014. godine na lokalitetima Krušedol i Neradin koji su smešteni na obodu fruškogorskog masiva, kao i lokalitetu Banatska Palanka koji se nalazi na obodu Deliblatske peščare..."

"The European ground squirrel (Spermophilus citellus, L. 1766) is endemic species to the Central and Southeastern Europe. Its recent range is divided in two main parts by the Carpathian Mountains. The northern part of the range is characterized by uniform steppe habitats at low altitudes, while the southern part is situated on the Balkan Peninsula, where different types of habitats, with different environmental conditions and at different altitudes are present. The majority of Serbian populations is located in the northern part of the country, i.e. in Vojvodina, while only a few small and isolated mountain populations are present in the east and southeastern part of the country. The European ground squirrel inhabits steppes, meadows and pastures covered with short grass. These once widely distributed habitats, which were commonly inhabited by European ground squirrels, had disappeared due to their intensive transformation into agricultural land during the past few decades. Today, species survives only in very isolated steppe-meadow fragments which are preserved within the dominant agricultural matrix. Given that a number of populations is continually declining throughout the range and that the future survival of the species is put in danger, the European ground squirrel has been protected since 2008 under the IUCN Red List of threatened species as a vulnerable species (VU). Its status in Europe is governed by the EU Habitats and Species Directive (Annexes II and IV) and the Convention on the Conservation of European Wildlife and Natural Habitats, known as the Bern Convention (Annex II). Also, 414 of its habitats are under protection regime within the Natura 2000 network. At the national level, European ground squirrel is protected by law as a strictly protected species. In order to analyze the genetic diversity and the structure of the European ground squirrel in Serbia, a total of 180 tissue samples from 11 localities (Krušedol, Neradin, Mala Remeta, Sremska Mitrovica, Banatska Palanka, Šušara, Mokrin, Lok and Tomislavci from area of Vojvodina, one locality from Vlasina and one from Stara Planina Mountain were collected during the 2007-2009. Density and abundance of the European ground squirrel populations were estimated during the period 2004-2014 on the localities Krušedol and Neradin, which are located on the periphery of Fruška Gora Mountain, as well as on the locality Banatska Palanka, which is located on the periphery of the Deliblato Sands..."

"Dijapauza je period zaustavljenog razvoja kod insekata, drugih zglavkara i određenih vrsta riba, a koja se javlja na određenom, za svaku vrstu karakterističnom, razvojnom stadijumu. Dijapauzu, kao dugotrajnu i „skupu“ fazu mirovanja, karakteriše prilagođavanje organizma na molekularnom, fiziološkom, morfološkom i bihevioralnom nivou. Promene koje karakterišu dijapauzu većine vrsta su supresija metabolizma, zaustavljanje ili usporavanje razvića, izmenjena ekspresija gena, sinteza zaštitnih proteina i metabolita koji vode ka povećanju otpornosti organizma. Sposobnost insekata da prežive dugotrajne nepovoljne periode u stanju dijapauze omogućila im je da koriste sezonski uslovljene resurse, kolonizuju raznovrsna staništa, smanjuju ukrštanje u srodstvu i povećavaju genetičku raznovrsnost. S obzirom na ogroman značaj dijapauze u životnom ciklusu insekata, ali i drugih organizama, bilo kakvo odlaganje ili njeno prerano prekidanje može imati negativne posledice na njihovo preživljavanje. Iz tog razloga, bolje poznavanje biološke osnove dijapauze može omogućiti unapređenje kontrole insekatskih vrsta koje nanose ekonomsku štetu u poljoprivredi, ali i poboljšanje metoda gajenja vrsta koje su korisne (bumbari, pčele, svilena buba, bubamare, parazitske osice i druge). Takođe, razumevanje mehanizama otpornosti i zaštite od stresa, npr. na niske temperature, mogu doprineti razvoju novih tehnika za krioprezervaciju organa i tkiva. Na kraju, insekti koji miruju, zbog specifičnosti metaboloma, mogu biti potencijalan izvor novih lekova, ali i dobri modeli za istraživanje starenja, gojaznosti i dijabetesa. Kukuruzni plamenac Ostrinia nubilalis (Hübner 1796) je vrsta moljca čije su larve polifagne herbivore koje se hrane na preko 200 biljnih vrsta, uključujući važne poljoprivredne useve, povrće i voće. Krajem leta i početkom jeseni larve 5. stupnja ulaze u fakultativnu dijapauzu, preživljavajući oštre kontinentalne zime u fazi mirovanja. Tokom dijapauze gusenice O. nubilalis razvijaju otpornost na niske temperature i sposobnost da prežive zamrzavanje vanćelijskih telesnih tečnosti, VIII što je omogućilo ovoj vrsti da nastani ogromna prostranstva Evroazije, ali i da nepažnjom čoveka nasele Severnu Ameriku..."

"Diapause is a carefully regulated state of arrested development that occurs at a species-specific life stage of insects, other arthropods and some fish species. It engages a plethora of molecular, physiological, morphological and behavioral changes that altogether increase stress tolerance and the ability to survive. Thus, diapause enables insects to exploit seasonally variable food resources and colonize new habitats, as well as decrease inbreeding and increase mating of temporally separated genotypes in a population. Due to the tremendous importance of diapause for survival, any factors that delay or perturb diapause can potentially compromise the fitness of an organism. Thus, deeper knowledge of the biology of diapause could help improve or develop new means of pest control for insect populations, as well as to advance current rearing techniques of beneficial species (bees, ladybirds, parasitic wasps, silkworm etc.). Additionally, defining the molecular background of stress tolerance during diapause, such as cold hardiness, could improve techniques for cryopreservation of organs, tissues and cells. Also, because of the specificity of the metabolom, diapausing insects could be regarded as a potentially rich source of new pharmaceutical agents, or could be used as model organisms to study ageing, obesity and diabetes. The European corn borer (ECB), Ostrinia nubilalis (Hübner 1796), is a pest moth species whose polyphagous larvae feed on more than 200 plants, including important crops, vegetables and fruits. In late August or the beginning of September, because of a critical shortening of the photoperiod, 5th instar larvae of ECB stop feeding and enter into diapause. Diapausing larvae gradually develop freeze tolerance and become cold hardy, which has enabled this species to successfully colonize temperate regions. The aim of this dissertation was to improve our understanding of the molecular and biochemical mechanisms governing diapause of O. nubilalis..."

"Spinalna mišićna atrofija (SMA) i amiotrofična lateralna skleroza (ALS) su bolesti motoneurona. SMA je najčešći monogenski uzročnik smrtnosti dece, dok je ALS adultna, neizlečiva bolest sa vrlo progresivnim tokom. SMA je uzrokovana homozigotnim odsustvom gena SMN1 u telomernom delu segmentalne duplikacije 5q13.2, dok se u njenom centromernom delu nalazi gotovo istovetan gen SMN2 koji daje ~10% funkcionalnog proteina SMN. Klinička prezentacija SMA je izuzetno varijabilna i kreće se od najtežeg oblika kod novorođenčadi (tip I) do blagog oblika sa adultnim početkom (tip IV). Homogenost uzročne mutacije i izražena fenotipska heterogenost ukazuju na postojanje genetičkih, epigenetičkih i sredinskih faktora koji modifikuju fenotip SMA. Visoka stopa nejednakih hromozomskih rearanžmana u segmentalnoj duplikaciji 5q13.2 dovodi do varijacija u broju kopija i strukturnih promena ne samo gena SMN, već i drugih prisutnih gena, poput SERF1 i NAIP, i one mogu uticati na tok i težinu bolesti. Dosadašnji podaci ukazuju na to da bi jednim delom uzrok fenotipskih razlika kod SMA mogao biti različit stepen metilacije promotora SMN2. Sporadična ALS (SALS) čini oko 90% svih slučajeva ALS i njena etiologija nije razjašnjena. Iako se genetička osnova, vreme pojave simptoma i tok SMA i SALS razlikuju, usled sličnosti patoloških promena i učešća proteina SMN i proteina asociranih sa ALS u zajedničkim molekularnim putevima, među genima kandidatima za nastanak i progresiju SALS velika pažnja usmerena je upravo na gene SMN. Cilj ove doktorske disertacije bio je ispitivanje genomske strukture, prirode rearanžmana i epigenetičkih oznaka u segmentalnoj duplikaciji 5q13.2 kod SMA bolesnika. Takođe, cilj je bio ispitivanje asocijacije broja kopija gena SMN1, SMN2, SERF1 i NAIP sa fenotipom dečije SMA, rizikom za nastanak SALS i preživljavanjem SALS bolesnika. U grupi od 99 SMA bolesnika i 122 roditelja bolesnika metodom umnožavanja većeg broja ligiranih proba (MLPA) analizirana su 442 hromozoma i identifikovano je 20 različitih alela telomernog dela duplikacije 5q13.2. Između broja kopija gena SMN2, SERF1 i NAIP i tipa dečije SMA uočena je statistički značajna obrnuto srazmerna korelacija (Spirmanov test korelacije, SMN2 p=2,2e-16, SERF1 p=4,264e-10, NAIP p=2,722e-8). Generalizovanim linearnim modelom i selekcijom unazad, počevši od punog modela koji je obuhvatio broj kopija SMN2, SERF1 i NAIP i njihove dvostruke interakcije, dobijen je najbolji minimalni model koji objašnjava fenotipsku varijabilnost dečije SMA i obuhvata broj kopija SMN2 (p<2e-16) i SERF1 (p<2e-16) i njihov udruženi efekat (p=0,026)..."

"Spinal muscular atrophy (SMA) and amyotrophic lateral sclerosis (ALS) are motor neurone diseases. SMA is the most frequent monogenic cause of infant mortality, whereas ALS is an incurable late-onset disease with an inexorably progressive course. SMA is caused by homozygous absence of the SMN1 gene located in the telomeric part of the 5q13.2 segmental duplication, while in its centromeric part resides a nearly identical copy named SMN2 producing only ~10% of functional SMN protein. Clinical presentation of SMA is extremely variable ranging from a severe infantile form (type I) to mild adult-onset form (type IV). Homogeneity of the disease-causing mutation and extensive phenotypic variability clearly indicate the existence of additional genetic, epigenetic and environmental factors modulating SMA phenotype. High rate of unequal crossing over in 5q13.2 segmental duplication results in copy number variations (CNVs) and complex structural rearrangements of the two SMN genes and other genes residing in the same region, such as SERF1 and NAIP, modulating disease progression and severity. Existing data suggest that, to some extent, phenotypic discrepancies in SMA might be due to differences in methylation level of the SMN2 promoter. Sporadic ALS (SALS) comprises ~90% of all ALS cases and has an unknown aetiology. Even though aetiology, age at onset and progression may differ between the diseases, due to similarities between ALS and SMA pathologies and the involvement of SMN and some ALS-associated proteins in common molecular pathways, SMN1 and SMN2 genes were repeatedly studied as SALS susceptibility genes. The aim of this doctoral thesis was to reconstruct genomic structure, the nature of rearrangements and epigenetic marks of the 5q.13.2 segmental duplication in SMA patients from Serbia. Furthermore, the aim was to investigate if copy numbers of the SMN1, SMN2, SERF1 and NAIP genes are associated with SMA type, susceptibility to SALS and survival in SALS patients from Serbia. In a group of 99 SMA patients and 122 patients’ parents 442 chromosomes were analysed by multiplex ligation-dependent probe amplification (MLPA) and 20 different alleles of the 5q13.2 telomeric part were observed. Statistically significant inverse correlation was found between SMN2, SERF1 and NAIP CNVs and SMA type (Spearman rank test, SMN2 p=2.2e-16, SERF1 p=4.264e-10, NAIP p=2.722e-8). Generalised linear model and backward selection, starting with a full model including the SMN2, SERF1 and NAIP copy number and their two-way interactions, revealed that the best minimal model explaining phenotypic variation in childhood-onset SMA with the smallest set of variables included the SMN2 (p<2e-16) and SERF1 (p<2e-16) copy number and their joint effect (p=0.02628)..."

"Seme tikve (Cucurbita pepo) obiluje kako uljem tako i proteinima. Nakon izdvajanja ulja, proteini se koncentrišu u uljanoj pogači, sekundarnom proizvodu procesa proizvodnje ulja, gde njihov sadrţaj dostiţe do 65%. Proteini semena tikve su primamljiv sastojak za prehrambenu, farmaceutsku i kozmetičku industriju zbog svoje farmakološke aktivnosti i visoke biološke vrednosti. Pored toga, budući da su mnogi proizvodi ovih industrija po svojoj koloidnoj prirodi emulzije, proteini semena tikve bi se u njima mogli naći i kao prirodne površinski aktivne materije. Međutim, koloidna funkcionalnost proteina semena tikve se još uvek potcenjuje zbog globularne strukture za koju se vezuju slabija funkcionalna svojstva u odnosu na proteine sa fleksibilnijom strukturom. Prema tome, cilj ove disertacije je ispitivanje funkcionalnih osobina proteinskog izolata semena tikve, pre svega njegovih adsorpcionih i emulgujućih svojstava, kao i ispitivanje uticaja promene proteinske strukture putem enzimske hidrolize na ispitivana svojstva. Pripremljeni su izolat proteina semena tikve (IPST) i dva enzimska hidrolizata, H1 i H2. IPST, H1 i H2 su okarakterisani određivanjem sadržaja vlage, proteina i pepela, zatim, određivanjem prinosa, molekulske mase i zeta potencijala. Ispitan je uticaj koncentracije proteina/peptida (0,0001–1 g/100 cm3), pH (3–8) i jonske jačine (0–1 mol/dm3 NaCl) na rastvorljivost i adsorpciona svojstva: dinamički međupovršinski pritisak (ulje/voda), statički površinski (vazduh/voda) i međupovršinski (ulje/voda) pritisak, kinetiku adsorpcije i dilatacionu reologiju proteinskih adsorpcionih filmova. Nakon toga, ispitan je i uticaj pomenutih parametara na emulziona svojstva IPST, H1 i H2. Emulgujuća svojstva IPST, H1 i H2 su okarakterisana na osnovu prosečnog prečnika kapljica emulzija, raspodele veličina kapljica i stabilnosti emulzija. Utvrđeno je da je prinos IPST veći od prinosa oba hidrolizata za oko 65 %. IPST ima najniţu rastvorljivost na pH=5, što ujedno predstavlja i njegovu izoelektričnu tačku. Enzimskom hidrolizom IPST značajno se povećava rastvorljivost, posebno na pI=5. Povećanje jonske jačine je izazvalo salting–in ili salting–out efekat rastvorljivosti kod svih uzoraka u zavisnosti od pH. IPST, H1 i H2 poseduju površinsku aktivnost pri čemu je površinski/međupovršinski pritisak H1 i H2 manje zavistan od promene pH i jonske jačine u poređenju sa površinskim/međupovršinskim pritiskom IPST. Adsorpcijom na granicu faza IPST i oba hidrolizata obrazuju adsorpcione filmove sa dominantnom elastičnom komponentom. Emulgujuća svojstva IPST, H1 i H2 zavise od koncentracije uzorka, pH vrednosti i jonske jačine kontinualne faze. Pri koncentraciji od 1 g/100 cm3 i Ic=0 mol/dm3 pripremljene emulzije su stabilne na svim pH osim emulzije IPST na pH 5. Sve emulzije podležu gravitacionoj nestabilnosti."

"Pumpkin (Cucurbita pepo) seed is rich source of both, oil and proteins. Once the oil has been extracted, proteins concentrate in oil cake, a by–product of the oil extraction process, where their content can reach up to 65%. Pumpkin seed proteins are desirable ingredient in food, pharmaceutical and cosmetic industry due to their pharmacological activities and high biological value. Moreover, since many of products of these industries are, in colloidal terms, emulsions, pumpkin seed proteins could serve as surface active materies. However, colloidal functionality of pumpkin seed proteins is still underestimated for their globular structure which entails inferior functional properties to functional properties of proteins with more flexible structure. Based on that, the aim of this dissertation is to investigate functional properties of pumpkin seed protein isolate, adsorption and emulsifying properties, in the first place, and then to investigate the influence of modification of the protein structure, by means of enzymatic hydrolysis, on the aforementioned properties. Pumpkin seed protein isolate, IPST, and two enzymatic hydrolysates, H1 and H2, were prepared. IPST, H1 and H2 were characterized by determination of moisture, ash and protein content, then, by determination of protein recovery, molecular mass and zeta potential. Influence of the protein/peptide concentration (0.0001–1 g/100 cm3), pH (3–8) i ionic strength (0–1 mol/dm3 NaCl) on the solubility and adsorption properties: dynamic interfacial (oil/water) pressure, static surface (air/water) and interfacial (oil/water) pressure, adsorption kinetics and interfacial dilatational properties, was investigated next. In the end, influence of the aforementioned pharameters on the emulsifying properties of IPST, H1 and H2 was investigated. Emulsifying properties of IPST, H1 and H2 were discussed in terms of mean droplet diameter, droplet size distribution and emulsion stability. Protein recovery of IPST was determined to be 65 % higher than recovery of H1 and H2. Solubility of IPST was the lowest at pH 5, what presents the isoelectric point. The enzymatic hydrolysis of IPST significantly increased solubility, especialy at the isoelectric point. Increase in the ionic strenght led to salting–in or salting–out effect depending on pH of the sample. Three investigated samples, IPST, H1 and H2 exhibited surface activity, however, sufrace/interfacial pressure of H1 and H2 were found to be less influenced by change in pH or ionic strenght of the solution in comparison to the IPST. Once adsorbed to the interface IPST and both hydrolysates form interfacial film with dominant elastic component. Emulsifying properties of IPST, H1 and H2 depend on the concentration, pH and ionic strength of the continuous phase. Stabile emulsions were formed at concentration of 1 g/100 cm3 and Ic=0 mol/dm3 regardless of pH, with the exception of the IPST at pH 5. All emulsions were susceptibile to gravitational separation."

"Mijeloidni maligniteti su klonalne bolesti ćelija mijeloidne krvne loze, koje su, pre svega, posledica poremećaja samoobnavljanja i diferencijacije hematopoetskih matičnih ćelija. Godišnja incidenca u Evropi je 7,5-8,6/100 000, a prosečna petogodišnja stopa preživljavanja pacijenata, uz primenu standardne terapije, je 37%. S obzirom da maligniteti najčešće nose više od jedne vodeće – ‘driver’ mutacije, pri čemu je velika intra- i interkancerska genetička heterogenost, postoji potreba za individualizovanim terapeutskim pristupom svakom pacijentu. Personalizovana medicina označava princip postizanja maksimalne terapijske efikasnosti kroz upotrebu ciljanih terapeutika kod biološki okarakterisanih pacijenata. Bioinformatika ima značajnu ulogu u identifikaciji ciljnih molekula za razvoj terapije, racionalnom dizajnu lekova i identifikaciji informativnih biomarkera za prateću dijagnostiku. Predmet istraživanja u ovom radu bili su geni i njihovi proteinski produkti koji imaju važnu ulogu u patogenezi mijeloidnih maligniteta. WT1 je transkripcioni faktor, koji kontroliše ekspresiju gena uključenih u apoptozu, proliferaciju i diferencijaciju. Ovaj gen ima povećanu ekspresiju u 70-90%, a mutiran je u ~10% akutnih mijeloidnih leukemija (AML) i učestvuje u preko 40 protein-protein interakcija, koje su vremenski i kontekstno zavisne. Mapiranje celokupne mreže WT1 kofaktora doprineće identifikaciji novih molekula i interakcija, koje su potencijalni targeti za ciljanu terapiju AML. Nedavno otkriven tumor supresor u karcinomu dojke, NISCH, ispoljava efekat preko RAC signalnog puta, koji je ključan u regulaciji hematopoeze i uključen u patogenezu mijeloidnih maligniteta, i smatra se atraktivnim targetom za ciljanu terapiju. Poznavanje funkcionalnih domena NISCH-a će omogućiti dizajn i optimizaciju jedinjenja sa antikancerskim delovanjem..."

"Myeloid malignancies are clonal diseases of myeloid cell line, which arise, primary, as a consequence of aberrant self-renewal and differentiation of hematopoietic stem cells. Annual incidence in Europe is 7.5-8.6/100 000 and the mean 5-year survival rate, with standard therapy, is 37%. Since malignancies often carry more than one driver mutation, with high intra- and inter-cancer genetic heterogeneity, there is a need for individualized therapeutic approach to each patient. Personalized medicine is based on the principle of achieving maximal therapeutic efficacy through the use of targeted drugs for biologically characterized patients. Bioinformatics has an important role in identification of molecules for targeted therapy, rational drug design and identification of informative biomarkers for companion diagnostics. The subject of this research included genes and their protein products that have important roles in the pathogenesis of myeloid malignancies. WT1 is a transcription factor that controls the expression of genes involved in apoptosis, proliferation and differentiation. This gene is overexpressed in 70-90%, mutated in ~10% of acute myeloid leukemia (AML) and it is engaged in more than 40 time- and context-dependant protein-protein interactions. Characterizing entire network of WT1 cofactors can improve identification of new molecules and their interactions that could be targets for therapy of AML. Recently identified tumor suppressor in breast cancer, NISCH, affects RAC signaling pathway, which is important in regulation of hematopoiesis and has a role in pathogenesis of myeloid malignancies, so it is considered an attractive target for targeted therapy. Characterization of functional domains of NISCH can enable design and optimization of compounds with anticancer effect..."

"Kako su plavne šume u Evropi vrlo fragilni ekosistemi i povećava se njihova ugroženost prevashodno antopopresijom, postoji rastuća potreba za povećanjem obima stavljanja sastojina ovih šuma pod specijalni režim zaštite. Upravo sprovdena, floristička i ekološka istraživanja u ovoj disertaciji obezbeđuju jednu širu ekološku osnovu za zaštititu prirodnih vrednosti ovih šuma i održivi menadžment nizijskih šumskih ekosistema, distribuiranih u plavnom i izvanplavnom području Ravnog Srema, ali i šre u svakom drugom šumskom području koje pripada kompleksu aluvijalnih higrofilnih šuma. Da bi se detektovala i analizirala bazična floristička diferencijacija tipološki izdvojenih jedinca šumske vegetacije, primenjeno je shodno odgavarujućim pravilima za različite setove vegetacijskih podataka niz ordinacionih metoda (CA, DCA, PCA i nMDS) a od klasifikcionih - UPGMA, kao hijerarhijski, aglomerativni metod. Da bi detektovali nivo florističkog ili ekološkog diskontinuiteta i njegovu statističku signifikantnost primenjena je ANOSIM analiza. Multivarijantnom SIMPER procedurom je dodatno kvantifikovan doprinos svakog pojedinačnog taksona ili faktora postojećem obrazcu ukupnog florističkog odnosno ekološkog diskontinuiteta između analiziranih setova vegetacijskih odnosno ekoloških podataka. Korespodentna analza (CA) i klasifikacioni UPGMA metod su pokazali da se u odnosu na recentno stanje florističkog sastava i sastojinske strukture nizijske šume plavnog i izvanplavnog područja Ravnog Srema diferenciraju na četiri velike grupe sastojina, koje u potpunosti korespondiraju sa cenoekološkim grupama tipova šuma: močvarne šume crne jove, šume bele vrbe i topola, šume lužnjaka i jove i šume lužmjaka i graba. Shodno multivarijantnoj ANOSIM analizi, utvrđeno je da najveći stepen florističkog diskontinuiteta postoji upravo između cenogrupe močvarne šume crne jove i cenogrupe lužnjaka i graba. Po osnovu SIMPER procedure najznačajnijim vrstama, koje doprinose (na ≈15% kumultativnog doprinisa) prethodno utvrđenom obrazcu florističkog diskontinuiteta sastojinske strukture, na nivou istraženih cenotipova, samtraju se sledećim redosledom: Amorpha fruticosa 2, Populus euroamericana cl. I -214 (1), Quercus robur 1, Amorpha fruticosa 3, Fraxinus angustifolia 1, Carpinus betulus 1 i Fraxinus angustifolia 3..."

"As floodplains in Europe are very fragile ecosystems, increasingly threatened by anthropopression, there is a growing need for increase in number of forest stands of this type placed under a special protection regime. The most recent floristic and ecological studies presented in this dissertation provide a wider ecological foundation for protection of natural values of these forests, as well as for sustainable management of lowland forest ecosystems distributed in the floodplain and out-of-floodplain areas, both in Ravni Srem and in any other forest area belonging to the complex of alluvial hygrophilous forests. In order to detect and analyze the basic floristic differentiation of typologically separated units of forest vegetation, a number of ordination methods (CA, DCA, PCA and nMDS) and the classification method UPGMA (as a hierarchical agglomerative method) were applied according to the scientifically recognized rules for various sets of vegetation data. The ANOSIM method was used in order to detect the level of floristic or ecological discontinuity and its statistical significance. The multivariate SIMPER procedure was used for additional quantification of contribution of each individual taxon or factor to the existing pattern of overall floristic or ecological discontinuity between the analyzed sets of vegetation or ecological data. The correspondent analysis (CA) and classification UPGMA method have shown that,regarding the recent condition of floristic composition and stand structure, the lowland forests of floodplain and out-of-floodplain areas of Ravni Srem are differentiated into four large groups of stands, completely corresponding with the coenoecological groups of forest types: Swamp forest of Black Alder, forests of White Willow and Poplar, forests of Pedunculate Oak and Alderand forests of Pedunculate Oak and Hornbeam. The multivariate ANOSIM analysis has shown the greatest degree of floristic discontinuity between the coeno-group of Swamp forest of Black Alder and the coeno-group of Pedunculate Oak and Hornbeam. According to the SIMPER procedure, the most important species (contributing with ≈ 15% of cumulative contribution) to the previously determined pattern of floristic discontinuity of stand structure at the level of studied coeno-types, are in following order: Amorphafruticosa 2, Populuseuroamericana cl. I -214 (1), Quercus robur 1, Amorphafruticosa 3, Fraxinusangustifolia 1, Carpinus betulus 1 andFraxinusangustifolia 3..."

"Protein Ankrd2 pripada familiji mišićnih proteina sa ankirinskim ponovcima (eng. Muscle Ankyrin Repeat Proteins – MARP). U sarkomeri ima ulogu strukturnog elementa i signalnog molekula u procesu mehanotransdukcije. Pod dejstvom fiziĉkih i hemijskih stresora migrira u jedro, gde ostvaruje ulogu regulatora transkripcije. Ekspresija Ankrd2 je indukovana mehaniĉkim stresom i zavisna od stepena diferencijacije mišićne ćelije i faze razvića organizma. Osim u skeletnim mišićima, protein ANKRD2 je u manjoj meri eksprimiran i u srcu ĉoveka. U cilju otkrivanja novih funkcija koje ANKRD2 ima u ovom organu odreĊeni su njegov profil ekspresije i lokalizacija u srcu ĉoveka i uporeĊeni sa karakteristikama homolognog ANKRD1, koji je eksprimiran samo u srcu i detaljno okarakterisan. Utvrdili smo da je nivo ekspresije ANKRD2 dosta niţi u poreĊenju sa ANKRD1 i da je preteţno lokalizovan u sarkomeri kardiomiocita. Interkalirajući diskovi su identifikovani kao novo mesto lokalizacije oba proteina. S obzirom da su ĉesto i uspešno korišćen model sistem za prouĉavanje funkcije srĉano-specifiĉnih gena, kardiomiociti neonatalnih pacova (KMNP) su okarakterisani po pitanju ekspresije i lokalizacije endogenog Ankrd2 i egzogenog ANKRD2. Ankrd2 je lokalizovan i u jedru i u citoplazmi KMNP, a sliĉnu dualnu lokalizaciju je pokazivao i egzogeno eksprimirani ANKRD2. Za razliku od inhibitornog dejstva na ekspresiju Ankrd1, kardiotoksiĉni agens doksorubicin nije doveo do promene nivoa ekspresije proteina Ankrd2 u KMNP. U ovoj tezi su okarakterisane tri izoforme ANKRD2 od 446 (L-ANKRD2), 360 (M-ANKRD2) i 333 (S-ANKRD2) aminokiselina. Diskriminacija izoformi u popreĉno prugastim mišićima ĉoveka je postignuta korišćenjem specifiĉno dizajniranih antitela i graniĉnika. Utvrdili smo brojne sliĉnosti izmeĊu izoformi S- i M-ANKRD2, kao i znaĉajne razlike koje mogu da se odraze na njihove specifiĉne funkcije. Izoforma LANKRD2 nije detektovana ni u srcu, ni u skeletnim mišićima..."

"Ankrd2 is a member MARP (Muscle Ankyrin Repeat Proteins) protein family. In sarcomere, it has a role of a structural element and signaling molecule in mechanotransduction. Ankrd2 is highly responsive to physical and chemical stress, which results in its translocation to the nucleus where it acts as a transcriptional regulator. Expression of Ankrd2 is upregulated in response to mechanical stresses such as exercise and stretch, as well as during muscle development and myoblast differentiation. Apart from skeletal muscles, ANKRD2 has been also detected in adult human heart, but at lower levels. In order to explore the cardiac-specific function of ANKRD2, we determined its expression and localization in human heart and compared them with the profiles of homologous cardiac protein ANKRD1. It was found that ANKRD2 is preferentially localized in sarcomere of cardiomyocytes and that level of its expression was lower when compared to ANKRD1. Intercalated disks were identified as a novel site of localization of both proteins. Neonatal rat cardiomyocytes (NRCM) are commonly used as a model system for functional analysis of cardiac-specific genes. One of the goals of this thesis was to characterize this model regarding expression and intracellular localization of endogenous Ankrd2 and exogenous ANKRD2. Nuclear and cytoplasmic localization of Ankrd2 was observed in NRCM, while similar dual localization was established for exogenous ANKRD2 as well. In the contrast to inhibitory effect on Ankrd1 expression, cardio-toxic drug doxorubicin did not change the protein level of Ankrd2 in NRCM. In this thesis we also characterized three ANKRD2 isoforms, containing 446 (LANKRD2), 360 (M-ANKRD2) i 333 (S-ANKRD2) amino acids. Their discrimination in human striated muscles was achieved by specifically designed antibodies and PCR primers. Various similarities between S- and M-ANKRD2 isoforms were discovered, as well as several significant differences, which could reflect on their specific functions..."

"Oralno zdravlje smatra se važnim delom opšteg zdravlja ljudi, ali je često zanemarena oblast, a razlozi tome su raznovrsni i kompleksni. Visoka učestalost oralnih oboljenja ima veliki socijalni i ekonomski uticaj. Najčešća oboljenja usne duplje su karijes, parodontalna oboljenja i oralne infekcije, dok su glavni uzročnici ovih oboljenja vrste rodova Streptococcus mutans-grupa, Staphylococcus, Lactobacillus, Pseudomonas, Enterococcus i Candida. Efikasan tretman i razvoj novih antiseptika koji poseduju antimikrobnu aktivnost je od velikog značaja za medicinu. Najčešće se koriste preparati koji sadrže hlorheksidin, povidon jod i cetilpiridinijum hlorid, zatim sintetička sredstva kao što su penicilin, cefalosporini, tetraciklini i njihovi derivati, nistatin, amfoterecin B, flukonazol itd. Ovi agensi poseduju antimikrobno dejstvo i kontrolišu upalu desni, ali imaju ograničenu efikasnost i veliki broj negativnih posledica kao što su bojenja zuba, iritacije sluzokože usne duplje, pojave alergije, nefrotoksičnost i endokrinu toksičnost, a povezuju se i sa kancerom i drugim sekundarnim oboljenjima. Problem rezistencije prema Svetskoj zdravstvenoj organizaciji je najveća pretnja globalnom zdravlju čoveka. Jedna od alternativa koja je poslednjih decenija u žiži naučnih interesovanja jesu etarska ulja kao izvor biološki aktivnih jedinjenja. U cilju dobijanja novih biološkli aktivnih jedinjenja, koja neće biti toksična za humane i animalne ćelije, u ovoj disertaciji analiziran je hemijski sastav i biološka aktivnost in vitro 60 komercijalnih uzoraka etarskih ulja ekstrahovano iz 47 biljnih vrsta: Cananga odorata, Foeniculum vulgare, Pimpinella anisum, Pastinaca sativa, Anethum graveolens, Matricaria recutita, Achillea millefolium, Helichrysum italicum, Boswellia carterii, Canarium luzonicum, Commiphora myrrha, Juniperus communis, J. virginiana, Gaultheria procumbens, G. fragrantissima, Pelargonium graveolens, Hyssopus officinalis, Mentha piperita, M. pulegium, Lavandula angustifolia, Thymus algeriensis, T. vulgaris, T. serpyllum, Rosmarinus officinalis, Salvia lavanudilifolia, S. officinalis, S. sclarea, S. triloba, Satureja montana, Laurus nobilis, Leptospermum petersonii, L. scoparium, Eucalyptus citriodora, E. globulus, Melaleuca alternifolia, M. quinquenervia, Syzygium aromaticum, Abies procera, A. grandis, A. alba, Pseudotsuga douglasii, Pinus silvestris, Piper nigrum, Cymbopogon martinii, Rosa centifolia, Citrus aurantium spp. aurantium i C.limon. Cilj rada je ispitivanje biološke aktivnosti i uticaja etarskih ulja i komponenti odabranih aromatičnih biljaka na mikroorganizme izolovane iz usne duplje čoveka i primena u prevenciji i lečenju oralnih bolesti i infekcija..."

"Oral health is considered an important part of general health, but is often neglected area, and the reasons for this are diverse and complex. The high incidence of oral disease has a huge social and economic impact. The most common diseases of the oral cavity are dental caries, periodontal disease, and oral infections, while the main causal agents of these diseases are species of genus Streptococcus mutans-group, Staphylococcus, Lactobacillus, Pseudomonas, Enterococcus and Candida. Effective treatment and developing new drugs that have antimicrobial activity is of great significance for medicine. The most commonly used preparations containing chlorhexidine, povidone iodine and cetylpyridinium chloride, followed by synthetic drugs such as penicillin, cephalosporins, tetracyclines and their derivatives, nystatin, amphotericin B, fluconazole, etc. These agents possess antimicrobial activity and control gum inflammation, but have limited efficacy and a large number of negative effects such as tooth staining, mucosal irritation, allergy, nephrotoxicity and endocrine toxicity, and are also associated with cancer and other secondary illnesses. The problem of resistance to the World Health Organization is the biggest threat to global human health. One of the alternatives that in recent decades are in focus of scientific interest are essential oils as a source of biologically active compounds. In order to obtain new biologically active compounds, which will not be toxic to human and animal cells, in this dissertation analysis of the chemical composition and biological activity in vitro of 60 commercial samples of essential oils extracted from 47 plant species were used: Cananga odorata, Foeniculum vulgare, Pimpinella anisum, Pastinaca sativa, Anethum graveolens, Matricaria recutita, Achillea millefolium, Helichrysum italicum, Boswellia carterii, Canarium luzonicum, Commiphora myrrha, Juniperus communis, J. virginiana, G . fragrantissima, Pelargonium graveolens, Hyssopus officinalis, Mentha piperita, M. pulegium, Lavandula angustifolia, Thymus algeriensis, T. vulgaris, T. serpyllum, Rosmarinus officinalis, Salvia lavanudilifolia, S. officinalis, S. sclarea, S. triloba, Satureja montana, Laurus nobilis, Leptospermum petersonii, L. scoparium, Eucalyptus citriodora, E. globulus, Melaleuca alternifolia, M. quinquenervia, Syzygium aromaticum, Abies procera, A. grandis, A. alba, Pseudotsuga douglasii, Pinus silvestris, Piper nigrum, Cymbopogon martinii, Rosa centifolia, Citrus aurantium spp. aurantium and C. limon..."

"Porodica mahunarki (Fabaceae) obiluje ekonomski i poljoprivredno značajnim vrstama među kojima se po zastupljenosti gajenja u Srbiji izdvaja grašak (Pisum sativum L.) sa udelom od 4,5% u ukupnoj povrtarskoj proizvodnji. Semenjače graška, posebno genotipova sa izrazito pigmentisanim tamnim semenima predstavljaju značajan izvor fenolnih jedinjenja čiji su sastav i biološke aktivnosti nedovoljno ispitani, te stoga ni potencijal ovog materijala nije iskorišćen na odgovarajući način. Semenjače graška čine i do 10% suve mase semena i uglavnom predstavljaju otpadni materijal koji nastaje u procesu industrijske izolacije proteina semena koji se koriste u humanoj i animalnoj ishrani. U ovom radu je ispitivan sadržaj fenolnih jedinjenja prisutnih u semenjačama deset evropskih genotipova graška kao i njihove biološke aktivnosti. Pored toga je ispitivan i uticaj različitih rastvarača, termičke obrade i in vitro digestije semena graška na prinos fenolnih jedinjenja i antioksidativne aktivnosti dobijenih ekstrakata. Dobijeni rezultati su pokazali da termički tretman i in vitro digestija dovode do statistički značajnog povećanja sadržaja fenolnih jedinjenja, kako u vodenim ekstraktima semena graška tako i u ekstraktima pripremljenim pomoću organskog rastvarača. Utvrđeno je da peptidi koji nastaju u toku in vitro digestije proteina semena graška mogu značajno interferirati sa testovima za određivanje antioksidativne aktivnosti, pogotovo u vodenim rastvorima, pošto i sami poseduju detektabilne antioksidativne aktivnosti. Pokazano je da kombinacija rastvarača koja sadrži 70% acetona, 29% destilovane vode i 1% sirćetne kiseline najpodesnije sredstvo za ekstrakciju ukupnih fenola iz semenjače graška, koje daje najveći prinos kako kod genotipova sa bledom, tako i kod genotipova sa izrazito tamno pigmentisanom semenjačom. Sadržaj ukupnih fenola u ekstraktima dobijenim primenom pomenutog rastvarača se kod pojedinih genotipova (Assas, MBK 168 и Aslaug) kretao u opsegu 41,8-46,6 mg GAE/ g s.m., što su najviše do sada zabeležene vrednosti kod graška. Isti genotipovi su ujedno sadržali najviše taninskih materija i antocijanina i pokazivali su najizraženije sposobnosti uklanjanja DPPH radikala i redukcije Fe3+ jona. Analizom ekstrakata semenjača pomoću UHPLC–LTQ OrbiTrap MS tehnike identifikovano je 25 najzastupljenijih fenolnih jedinjenja i tom prilokom je detektovano 9 jedinjenja čije prisustvo do sad nije bilo zabeleženo u semanjačama graška..."

"The family of legumes (Fabaceae) is rich in economicaly and agriculturally important species among which the most abundant in Serbia stands peas (Pisum sativum L.) with a share of 4.5% of the total vegetable production. Pea seed coats, especially in genotypes with highly pigmented dark seeds are an important source of phenolic compounds, whose composition and biological activity have not been tested in detail, thus this valuable material is still underutilized. Pea seed coat makes up to 10% of the seed dry weight and largely represents waste material generated in the process of industrial isolation of seed proteins, which are used in human and animal nutrition. In this study the content of phenolic compounds in seeds of ten European pea genotypes, as well as their biological activities has been examined. In addition, the effect of different solvents, heat treatment and in vitro digestion of pea seeds on yield of phenolic compounds and antioxidant activity in extracts was also studied. The obtained results showed that the thermal treatment and in vitro digestion led to a statistically significant increase of the total phenolic content, both in aqueous extracts of pea seeds and in the extracts prepared by using an organic solvent. It was shown that peptides which were formed during the in vitro digestion of the pea seed proteins can significantly interfere with the assays for determination of antioxidant activity, especially in aqueous solutions, since they possess a detectable antioxidant activity. It has been shown that the combination of solvents containing 70% acetone, 29% distilled water and 1% acetic acid was the most suitable means for the extraction of total phenols from pea seed coats, which gave the highest yield in both bright colored and dark colored seed genotypes. Total phenolic content of extracts obtained by mentioned solvent in certain genotypes (Assas, MBK 168 and Aslaug) ranged from 41.8 to 46.6 mg GAE / g s.m., which are the highest recorded values in pea. The same genotypes also possessed the highest tannin and anthocyanin content and showed the most pronounced ability for DPPH radical scavenging as well as for the reduction of Fe 3+ ions. The analysis of seed coat extracts, using the LTQ Orbitrap UHPLC-MS technique, identified 25 most abundant phenolic compounds, from which 9 compounds have not been recorded in pea seed coats of previously studied genotypes..."

"Crni američki patuljasti som (Ameiurus melas Rafinesque, 1820) je najzastupljenija i najuspešnija alohtona vrsta ribe koja naseljava kopnene vode Evrope. Istraživanja koja su sprovedena u proteklih nekoliko godina ukazuju na to da je ovo dominantna invazivna vrsta i u mnogim kopnenim vodama u Srbiji. Cilj istraživanja se odnosio na ispitivanje populacionih atributa patuljastog soma u Savskom jezeru, kao i na bioakumulaciju teških metala i mikroelemenata u različitim tkivima. Terenska istraživanja vršena su u periodu od 2009. do 2012. godine. Jedinke su uzorkovane jednom mesečno, četiri dana za redom. Laboratorijska obrada prikupljenih uzoraka obuhvatila je merenje totalne dužine tela (TL) i ukupne težine tela ulovljenih primeraka. Nakon disekcije jedinki merena je težina tela bez utrobe, kao i masa jetre i gonada.Struktura populacije utvrđena je kombinovanjem dve metode – analizom starosti jedinki i analizom dužinskih frekvencija. Starost jedinki određena je takođe uz pomoć dve metode – očitavanjem naraštajnih zona otolita i Batačarija metodom. Analiza uzrasne strukture populacije pokazala je prisustvo pet uzrasnih kategorija: od 0+ do 4+. Klasa 1+ bila je najdominatnija uzrasna klasa, kako po godinama, tako i po sezonama uzorkovanja. Prosečna totalna dužina jedinki iznosila je 13,3 cm, a prosečna težina 38,26 g. Prosečna relativna težina jedinki u Savskom jezeru, u celokupnom uzorku, iznosila je 84,78 ± 1,09 g. Utvrđeno je prisustvo ukupno 8 kohorti. Na osnovu analize dužinsko-težinskih odnosa izračunate su i vrednosti faktora alometrije b koje su se kretale od 2,93 do 3,16, dok je vrednost ovog faktora u celom poduzorku iznosila 3,00. Analizom krive dužinsko-težinskog odnosa utvrđeno je da tačka infleksije ne postoji. Ribolovni napor (CPUE) je korišćen za analizu distribucije i relativne gustine jedinki, kako po staništima, tako i po godinama uzorkovanja i sezonama. Tokom 2009, 2010. i 2012. godine CPUE vrednosti varirale su od 0,4 ± 0,5 do 41,5 ± 22,1 jedinki po vrši po danu..."

"abundant and successful non-native fish species in European freshwaters. Recent studies indicate that the black bullhead is one of the most dominant invasive fish species in Serbian waters as well. The aim of this research was to determine the population characteristics of this species in Sava Lake, as well as bioaccumulation of heavy metals and trace elements in different tissues. Fieldwork was conducted from 2009 to 2012. Black bullhead samples were collected monthly, for four days in a row. Once in the laboratory, specimens were measured for their total length (TL) and body weight (W). After dissection, the eviscerated body weight was measured, as well as liver and gonad weights. Population structure was determined by combining two methods – analyzing age and length-frequency distributions. Age was determined by combining otolith examination and Bhattacharya’s method. Age structure analysis has revealed the presence of five age classes: from 0+ to 4+. The class 1+ was the most dominant, by both year and season of sampling. The average total length was 13.3 cm and the average weight was 38.26 g. The mean value of the relative weight, across the entire sample, was 84.78 ± 1.09. The research revealed the presence of eight cohorts, in total. The length-weight allometric factor b ranged from 2.93 to 3.16, while the value of this factor, across the entire sample, was 3.00.The analysis of the length-weight relationship curve showed an absence of inflection points. Catch-per-unit-effort (CPUE) was used as an indicator of the black bullhead distribution and abundance in different habitats, years of sampling, and seasons. In 2009, 2010, and 2012, CPUE values fluctuated and ranged from 0.4 ± 0.5 to 41.5 ± 22.1 ind./net/night, while in 2011 they were low and rather uniform, ranging from 0.2 ± 0.3 to 3.4 ± 4.5 ind./net/night. CPUE values were highest in the macrophyte vegetation zone, as well as during autumn and spring..."

"Regeneracija in vitro gajenog biljnog tkiva kontrolisana je regulatorima rastenja, naročito citokininima i auksinima. Egzogeno primenjeni biljni regulatori rastenja mogu interagovati sa endogenim biljnim hormonima i uticati na njihovu biosintezu ili distribuciju, odnosno menjati hormonalnu homeostazu koja utiče na razviće in vitro. Proces regeneracije biljaka in vitro podrazumeva intenzivne ćelijske deobe, a centralnu ulogu u kontroli ćelijskog ciklusa i razvića organa imaju kompleksi ciklina i kinaza zavisnih od ciklina na čiju sintezu, odnosno aktivnost, utiču pomenuti biljni hormoni. U tom smislu, ciljevi ovog rada bili su uspostavljanje efikasnih protokola za regeneraciju biljaka kelerabe (Brassica oleracea L. var. gongylodes) in vitro, sa posebnim osvrtom na identifikaciju i kvantifikaciju različitih grupa citokinina i indol-3-sirćetne kiseline (IAA) u eksplantatskim tkivima sa regenerisanim izdancima, kao i analiziranje obrazaca i intenziteta ekspresije gena koji kodiraju cikline i kinaze zavisne od ciklina tokom de novo organogeneze izdanaka. Efikasan sistem za repetitivnu somatsku embriogenezu (SE) kod kelerabe, sorta Bečka Plava (BP), je uspostavljen iz nezrelih zigotskih embriona. Najveća frekvencija SE detektovana je kod nezrelih zigotskih embriona u ranom kotiledonarnom stadijumu razvića gajenih na hranljivoj podlozi bez regulatora rastenja. Uspešna indukcija de novo organogeneze izdanaka kelerabe, sorte BP i Bečka Bela (BB), postignuta je kod odsečaka hipokotila i intaktnih klijanaca, na podlogama sa pojedinačnim citokininima (CK): 6-benzilaminopurin (BAP), tidiazuron (TDZ), transzeatin (transZ) ili cis-zeatin (cisZ). Frekvencija regeneracije kao i vijabilnost regenerisanih izdanaka obe sorte je bila veća kod intaktnih klijanaca, dok su među primenjenim citokininima BAP i TDZ bili najefikasniji u indukciji de novo organogeneze. Kvantifikacija endogenog sadržaja citokinina i IAA u odsečcima hipokotila sa regenerisanim izdancima (HRI) kao i u intaktnim klijancima sa regenerisanim izdancima (KRI) je ukazala na to da uočene razlike u organogenom odgovoru ova dva tipa početnog biljnog materijala mogu biti povezane sa njihovim hormonskim statusom..."

"vitro plant regeneration is under control of plant growth regulators (PGRs), especially cytokinins and auxins. Exogenously applied PGRs can affect the homeostasis of endogenous plant hormones by influencing their biosynthesis and distribution, subsequently altering in vitro development. Intensive cell divisions represent the basis of in vitro plant regeneration, and they are controlled by complexes of cyclins and cyclin-dependent kinases. The activity of these complexes during cell cycle and organ development is affected by plant hormones. Respecting this, the aims of this study were developing efficient protocols for in vitro regeneration of kohlrabi (Brassica oleracea L. var. gongylodes) with an emphasis on identification and quantification of different groups of endogenous cytokinins and indole-3-acetic acid (IAA) in explant tissue with respective regenerated shoots, as well as analyzing expression of genes encoding cyclins and and cyclin-dependent kinases during de novo shoot organogenesis. Efficient system for repetitive somatic embryogenesis (SE) was developed for kohlrabi cv. Vienna Purple (VP) using immature zygotic embryos. The highest frequency of SE was obtained from immature zygotic embryos at the early cotyledonary stage grown on PGR-free medium. Successful induction of de novo shoot organogenesis in kohlrabi cv VP and cv. Vienna White (VW) was achived using hypocotyl explants and intact seedlings, cultivated on media supplemented with single cytokinin (CK): 6-benzylaminopurine (BAP), thidiazuron (TDZ), trans-zeatin (transZ) or cis-zeatin (cisZ). Higher frequency of shoot regeneration as well as viability of regenerated shoots was detected for intact seedlings, with BAP and TDZ being the most efficient in de novo organogenesis induction. Quantification of endogenous cytokinin and IAA contents in both hypocotyl explants and seedlings with regenerated shoots (HRSs and SRSs, respectively) suggested that the observed differences in organogenic response between these two types of starting plant material were related to their cytokinin and IAA contents. The level of total CKs was higher in HRSs, while SRSs displayed a higher IAA/bioactive CKs ratio..."

"Specifičan antigen prostate (prostate-specific antigen; PSA) ili kalikrein 3 (hK3), pripada grupi ekstracelularnih serin-zavisnih proteaza iz porodice kalikreina. PSA u najvećoj meri eksprimiraju epitelne ćelije acinusa i duktusa prostate i periuretralne žlezde, a u manjoj meri i neka druga tkiva. PSA je, u normalnim fiziološkim uslovima, prisutan u semenoj tečnosti u izrazito visokoj koncentraciji za razliku od seruma gde je ona veoma niska. Usled narušene strukture prostate, do koje može doći pri različitim poremećajima i oboljenjima, nivo PSA se u sistemskoj cirkulaciji znatno povećati pa se on koristi kao serumski biomarker. Brojne studije su pokazale da PSA nije, u striktnom smislu, specifičan samo za prostatu, već da ga eksprimiraju i neka hormon-zavisna tkiva žene, pre svega dojka, endometrijum i ovarijum, kako u normalnom, tako i u patološkim stanjima. Ekspresija gena za PSA je, u tkivu prostate, regulisana androgenima, dok je, u ćelijskim linijama kancera dojke ona posredovana aktivacijom receptora za progesteron, androgene, mineralokortikoide i glukokortikoide, ali ne i receptora za estrogene. PSA je glikoprotein molekulske mase 28,43 kDa, koji sadrži jedan biantenaran lanac N-acetil-laktozaminskog tipa sa sijalinskom kiselinom na krajevima obe grane. Ovi podaci se odnose na kanonsku sekvencu/strukturu enzimski aktivnog molekula PSA. On se u cirkulaciji nalazi u kompleksima sa inhibitorima proteaza kao što je α1-antihimotripsin (ACT) ili α2-makroglobulin, ali pored njega postoje i molekuli PSA koji nemaju enzimsku aktivnost ili je ona znatno smanjena. Njihova zastupljenost u kompleksima je niska i oni predstavljaju formu slobodnog PSA (fPSA). Za razliku od ispitivanja PSA formi, njegove pojedinačne molekulske vrste koje pripadaju ovim formama do sada nisu bile predmet sistematske analize. Proteinska vrsta je najmanja strukturna i funkcionalna jedinica proteoma i označava jedan individualan protein iz familije proteina koji kodira pojedinačan gen. Ispitivanje specijacije proteoma i kinetike njegovih proteinskih vrsta se nalazi u fokusu savremenih proteomskih istraživanja. Cilj ove doktorske disertacije je da se ustanovi profil molekulskih vrsta PSA u subproteomima klinički relevantnih bioloških tečnosti: serum, urin i semena plazma..."

"Uvod: Nasledni karcinom čini 5-10% od svih slučajeva karcinoma dojke i prvenstveno je povezan sa štetnim mutacijama u visoko penetrabilnim genima BRCA1 i BRCA2. I pored intenzivnog istraživanja ostatka nasledne komponente, treći visoko penetrabilni gen u karcinomu dojke (BRCA3) još uvek nije pronadjen. Pod okriljem poligenog modela otkrivene su tri grupe alela koji doprinose riziku za karcinom dojke: visoko penetrabilni, koji povećavaju rizik na 40-85% (BRCA1, BRCA2, TP53), srednje penetrabilni (povećavaju rizik na 20-40%) kao što su CHEK2, RAD51, RAD51C i XRCC1, i učestale genske varijante koje su nisko penetrabilne. Pored štetnih mutacija u ovim genima, odredjene polimorfne varijante mogu uticati na efikasnost popravke grešaka u DNK i na nastanak karcinoma. Cilj: Obzirom da prisustvo mutacija u BRCA1/2 genima ne može da opiše celu genetičku osnovu naslednog karcinoma dojke, cilj ovog rada je istraživanje prisustva populaciono specifičnih mutacija u drugim genima (TP53, CHEK2, NBS1, RAD51, RAD51C i XRCC1) kod BRCA1/2 negativnog, naslednog karcinoma dojke u Srbiji. Utvrdjivanje asocijacije polimorfnih varijanti u ovim genima sa rizikom za nastanak karcinoma dojke, kao i njihove korelacije sa parametrima tumora i parametrima domaćina tumora, predstavlja dodatni cilj ovog rada. Materijal i metode: 57 ispitanika poreklom iz visokorizičnih porodica kod kojih je sekvenciranje BRCA1/2 gena dalo negativan rezultat (nasledni uzorak) i 107 pacijentkinja sa karcinomom dojke koji nije odredjen u odnosu na porodičnu istoriju bolesti (sistematski uzorak), uključeno je u ovu studiju. Kontrolnu grupu je činilo 114 briseva grlića materice zdravih žena sa normalnim Papa nalazom i bez prethodne istorije pre-kancerskih i kancerskih lezija..."

"Background: 5-10% of all breast cancer cases are hereditary, and are often caused by deleterious mutations in high penetrance BRCA1 and BRCA2 genes. Despite significant efforts in unraveling the rest of the familial component, BRCA3 could not be identified. Under the polygenic model of inheritance, three groups of genetic predisposition alleles have been identified so far: high-risk genes, conferring 40–85% lifetime risk (BRCA1, BRCA2, TP53), moderate-risk genes (20–40% lifetime risk) including CHEK2, RAD51, RAD51C and XRCC1, and low-risk common alleles. Besides the deleterious mutations in these genes, certain polymorphic variants have functional significance in DNA repair pathways, and may be responsible for cancer development. Aim: Considering the fact that mutations in BRCA1/2 can’t explain the whole range of hereditary predisposition to breast cancer, we aimed to investigate the presence and frequency of population-specific mutations in other susceptibility genes (TP53, CHEK2, NBS1, RAD51, RAD51C and XRCC1) in BRCA1/2 negative hereditary breast cancer cases in Serbia. Determining association between polymorphic variants in these genes with breast cancer risk, as well as their correlation with patient’s characteristics and histological and pathological characteristics of breast cancer, were also the aims of this study. Material and methods: 57 subjects from high-risk families negative for small alterations in BRCA1/2 genes (hereditary group) and 107 breast cancer patients non-selected according to family history (consecutive group) were included in the study. The control group was consisted of 114 cervical smears of gynecological healthy women with normal Papa test results and without previous history of pre-cancer and cancer lesions. Large genomic rearrangements in BRCA1/2 genes were investigated by MLPA technique, while genotyping for specific CHEK2 mutations was done by allele specific PCR..."

"Cilj: Ispitati učestalost i distribuciju mikrometastatskih limfnih nodusa hepatičnog sliva i prognostički značaj rutinske regionalne limfadenektomije s posebnim osvrtom na pojavu recidiva maligne bolesti. Metod: Ukupno 50 bolesnika sa metastatskom bolesti jetre podvrgnuto je resekciji jetre sa rutinskom limfadenektomijom. Rezultati: Pozitivni limfni nodusi hepatičnog sliva prisutni su kod 14 bolesnika (28%) bolesnika. Standardna H&E patohistološka analiza verifikuje 6 bolesnika (12%) sa pozitivnim limfnim nodusima hepatičnog sliva. Imunohistohemijska analiza dodatno verifikuje još 8 bolesnika (16%) pozitivnih limfnih nodusa hepatičnog sliva preostalih limfnih nodusa. Limfni nodusi duž zajedničke hepatične arterije (grupa 8a i 8p) najčešće sadrže mikrometastaze kolorektalnog karcinoma (53,84%, i 19,23%). MSCT trbuha je od koristi za preoperativnu dijagnostiku limfadenopatije (18,42%). Slobodni interval do pojeve metastaza je u proseku 15 meseci. Recidiv maligne bolesti javio se kod 38,0% bolesnika. Volumen metastatske bolesti jetre značajan faktor recidiva maligne bolesti (p<0,05) Zaključak: Rutinska limfadenektomija hepatičnog sliva je bezbedna i preporučljiva procedura u prevenciji širenja kolorektalne metastatske bolesti, koja neznatno povećava vreme trajanja operacije u celini (prosečno 32 minuta) i ne povećava učestalost postoperativnih komplikacija."

"Objective: To investigate the frequency and distribution of micrometastatic lymph nodus of the hepatic basin and the prognostic significance of routine regional lymphadenectomy with particular reference to the occurrence of relapse of malignant disease. Methods: A total of 50 patients with metastatic liver disease underwent resection of the liver with routine lymphadenectomy. Results: Positive lymph nodes of the hepatic basin are present in 14 patients (28%) of patients. The standard H & E pathohistological analysis verifies 6 patients (12%) with positive lymph nodes of the hepatic basin. Immunohistochemical analysis further verified another 8 patients (16%) of positive lymph nodes of the hepatic basin of the remaining lymph nodes. Lymph nodes along the common hepatic artery (group 8a and 8p) most commonly contain colorectal carcinoma micrometastases (53.84%, and 19.23%). MDCT abdomen is beneficial for preoperative diagnosis of lymphadenopathy (18.42%). The free interval to metastasis rates is on average 15 months. The recurrence of malignancy occurred in 38.0% of patients. The volume of metastatic liver disease is an important factor of relapse of malignant disease (p <0.05). Conclusion: Routine lymphadenectomy of the hepatic basin is a safe and recommended procedure in the prevention of the spread of colorectal metastatic disease, which slightly increases the duration of the operation as a whole (an average of 32 minutes) and does not increase the incidence of postoperative complications."

"Sastav masnih kiselina lipida, posebno fosfolipida (PL) glavnih konstituenata ćelijskih membrana zavisi od brojnih faktora. U poslednje vreme povećano je interesovanje za istraživanja novih antioksidanasa u ishrani, uključujući omega-3 masne kiseline i bioaktivne proteine prisutne u mleku. Uticaj različitih vrsta hrane, odnosno njihovog masnokiselinskog sastava na profil masnih kiselina fosfolipida tkiva nije dovoljno ispitivan. Stoga, cilj ove doktorske disertacije je bio ispitivanje efekta unosa tri različite vrste hrane (standardne hrane, hrane obogaćene ribljim brašnom i hrane obogaćene mlekom u prahu) na biohemijske parametre u krvi, masnokiselinske profile fosfolipida jetre i na parametre oksidativnog stresa u jetri pacova Wistar soja, starosne dobi četiri meseca u trajanju od četiri nedelje. U okviru ove studije, poređen je manokiselinski profil u hranama različitog sastava, a takođe i u fosfolipidima jetri životinja nakon tretmana. Preciznije, cilj je bio izdvajanje pojedinačnih masnih kiselina, koje su najviše doprinele razlici u sastavu fosfolipida jetre, kao i ispitivanje polno specifičnog odgovora tkiva na primenjene vrste hrane. Rezultati ove disertacije su pokazali da hrana obogaćena ribljim brašnom i hrana obogaćena mlekom u prahu menja sastav masnih kiselina fosfolipida i njihov odnos u jetri pacova, na polno specifičan način. Primenjene hrane su promenile odnos ukupnih zasićenih (SFA), mononezasićenih (MUFA) i polinezasićenih masnih kiselina (PUFA), ali su efekti polno specifični. Hrana obogaćena mlekom u prahu je smanjila sadržaj SFA i povećala udeo MUFA kod mužjaka, i PUFA kod ženki, u odnosu na standardnu hranu. Ista vrsta hrane je smanjila procenat ukupnih n-3, povećala procenat ukupnih n-6 i odnos n-6/n-3 kod mužjaka u odnosu na druge vrste hrana. S druge strane, kod ženki, hrana obogaćena ribljim brašnom povećala je procenat ukupnih n-3, smanjila procenat ukupnih n-6 i odnos n-6/n-3 u poređenju sa standardnom hranom i hranom obogaćenom mlekom u prahu.

"The composition of fatty acids especially phospholipids (PL) as the main constituents of cell membranes depends on many factors. Recently, there has been an increased interest in novel dietary antioxidants, including omega-3 fatty acids and bioactive proteins present in milk. There is limited data regarding the effects of fatty acid composition of different types of diets on tissue phospholipids fatty acid profile. The aim of this doctoral dissertation was to examine the effects of different types of diets (standard diet, fish based and milk based diets) on plasma biochemical parameters, FA profiles of liver phospholipids, and parameters of oxidative stress in liver, of four months old Wistar rats, during four-weeks. Within this study, fatty acid profile was compared in diets of different composition, as well as in liver phospholipids of animals after treatment. The aim was to detect individual fatty acids mostly contributed to the difference in composition of liver phospholipids, and to explore the association of tissue response with gender. The results of this dissertation have shown that both, milk- and fish-based diet, changed the composition and ratio of rat liver phospholipids FA, in gender-specific manner. Although, applied diets changed the ratio of total saturated fatty acids (SFA), monounsaturated fatty acids (MUFA) and polyunsaturated fatty acids (PUFA), but the effects were sex specific. Milk-based diet lowered the amount of SFA and elevated the ratio of MUFA in males, and PUFA, in females comparing to standard diet. The same diet decreased n-3, increased n-6 and n-6/n-3 ratio in males comparing to the other type of diets. On the other hand, in females, fish-based diet increased n-3, decreased n-6 and n-6/n-3 ratio comparing to standard and milk-based diet. However, the ratio of individual FA in liver PL was also dietary-influenced, but with gender specific manner. While in females fish-based diet decreased AA (arachidonic acid) increased level of EPA (eicosapentaenoic acid), DPA (docosapentaenoic acid) and DHA (docosahexaenoic acid), the same diet elevated only DHA levels in males..."

"Teški metali, čija se koncentracija u sredini sve više povećava kao rezultat povećane industrijske aktivnosti i tehnološkog razvoja, ubrajaju se u najčešće zagađivače životne sredine. Kada su prisutni u većim koncentracijama toksični su i predstavljaju ozbiljnu pretnju kako za životnu sredinu tako i za zdravlje ljudi, jer se ne mogu razgraditi i jer se nagomilavaju u lancima ishrane. Sa druge strane, ovakve sredine predstavljaju dobar izvor mikroorganizama tolerantnih na teške metale, sa potencijalnom primenom u biološkom uklanjanju (bioremedijaciji) i oslobađanju (bioluženju) teških metala. Cilj ovog rada je bila izolacija, identifikacija, analiza diverziteta i aplikativnog potencijala novih bakterijskih sojeva sa sposobnošću tolerancije visokih koncentracija teških metala iz površinskog i podzemnog sedimenta iz rudnika bakra Bor. Metagenomskom analizom je detektovan veći mikrobiološki diverzitet u uzorku površinskog sedimenta u poređenju sa podzemnim sedimentom. Iz oba uzorka je izolovano 6 bakterija tolerantnih na visoke koncentracije teških metala, primenom direktne kultivacije. Ovi izolati su taksonomski identifikovani kao predstavnici rodova Arthrobacter i Staphylococcus. Pored ovih izolata, u ovu studiju je bilo uključeno još 8 sojeva za koje je tolerancija na metale prethodno opisana u literaturi, tako da je aplikativni potencijal slobodnoživećih bakterija i definisanih bakterijskih zajednica, kao i njihovih biofilmova, ispitan kod ukupno 14 sojeva. Među 14 testiranih sojeva, 6 sojeva je imalo sposobnost rasta u prisustvu nikla, 6 u prisustvu kadmijuma, 4 u prisustvu bakra, 3 u prisustvu hroma i 1 je imao sposobnost rasta u prisustvu žive, dok nijedan od sojeva nije imao sposobnost rasta u prisustvu gvožđa i cinka. Izdvojio se izolat Staphylococcus sp. MSI08, koji je jedini imao sposobnost rasta u prisustvu tri teška metala (nikl, kadmijum, hrom). Analizom genetičkih determinanti mehanizama tolerancije na teške metale, kod 2 soja je detektovano prisustvo gena za determinantu tolerancije na kadmijum, kod 2 soja prisustvo gena za determinantu tolerancije na hrom i kod 2 soja je detektovano prisustvo gena za determinantu tolerancije na bakar. Svi testirani sojevi su imali sposobnost formiranja biofilmova, s tim što su najveći potencijal za formiranje biofilmova pokazali Staphylococcus sp. MUI10, Arthrobacter sp. MSI31, Pseudomonas aeruginosa PAO1 i Cupriavidus metallidurans CH34, dok su Staphylococcus sp. MSI08, Rhodococcus sp. TN113, Pseudomonas putida KT2440 i Cupriavidus necator H16 pokazali nešto slabiji potencijal za formiranje biofilmova..."

"Heavy metals are one of the most common environmental pollutants due to increased industrial activities and technological development. When present in excessive concentrations, heavy metals are highly toxic and they pose a serious threat both to environment and human health, due to their persistence in nature and accumulation in the food chain. On the other hand, polluted sites have proven to be valuable sources of bacteria capable to tolerate increased concentration of heavy metals that could be potentially applied in biological removal (bioremediation) and release (bioleaching) of heavy metals. The aim of this study was to obtain, identify, analyze diversity and application potential of novel bacterial strains with the ability to tolerate high heavy metal concentrations from surface and underground sediments from the copper mine Bor. Metagenomic analysis revealed a higher microbial diversity in surface sediment compared to underground sediment. From both sediments, 6 bacterial strains able to tolerate high heavy metal concentrations were isolated using direct cultivation approach. These isolates were taxonomically identified as members of Arthrobacter and Staphylococcus genus. In addition, this study involved 8 more strains with heavy metal tolerance previously described in the literature. Thus, 14 bacterial strains were included in analysis and evaluation of heavy metal tolerance and application potential of free living bacteria and defined bacterial consortia, as well as their biofilms. Among 14 tested strains, 6 strains had the ability to grow in the presence of nickel, 6 in the presence of cadmium, 4 in the presence of copper, 3 in the presence of chromium and 1 had the ability to grow in the presence of mercury, while none of the strains had the ability to grow in the presence of iron and zinc. Staphylococcus sp. MSI08 singled out as the only strain with the ability to grow in the presence of three heavy metals (nickel, cadmium, chromium). Analysis of genetic determinants conferring heavy metal tolerance revealed presence of cadmium tolerance genes in 2 strains, chromium tolerance genes in 2 strains, and copper tolerance genes were also detected in 2 strains. All strains showed ability to form biofilms, but Staphylococcus sp. MUI10, Arthrobacter sp. MSI31, Pseudomonas aeruginosa PAO1 and Cupriavidus metallidurans CH34 demonstrated the highest potential for the biofilm formation, while Staphylococcus sp. MSI08, Rhodococcus sp. TN113, Pseudomonas putida KT2440 and Cupriavidus necator H16 were less successful in biofilm formation..."

"Prirodni antrahinoni, važna klasa hinonskih jedinjenja, se mogu naći u velikom broju viših biljaka, mahovinama, lišajevima kao i drugim organizmima. Ova hinolna jedinjenja poseduju laksativno, antibiotičko, antiinflamatorno i antipiretičko kao i antiviralno dejstvo, a njihov potencijal u tretmanu kancera, i inhibiciji proliferacije i metastaziranja malignih ćelija ih čini jednom od najzanimljivijih grupa jedinjenja u razvoju novih terapeutika. Njihov mehanizam dejstva podrazumeva učešće u metaboličkim procesima, oksidativnoj fosforilaciji, interkalalaciju u DNK i RNK molekule, inhibiciju telomeraze i topoizomeraze II. Najpoznatija podgrupa ove klase jedinjenja su antraciklini, antrahinonski antibiotici. Antraciklini kao što su doksorubicin i daunorubicin imaju izuzetno široku primenu u terapiji kancera, mada su izuzetno kardiotoksični. Tiosemikarbazoni predstavljaju grupu iminskih derivata koji sadrže atom sumpora u svom molekulu, i odlikuje ih izuzetna sposobnost helacije jona metala. Odlikuje ih antiviralno, antibakterijsko, antifungalno, kao i citotoksično i antiproliferativno dejstvo. Halkoni su prekursori flavonoida i izoflavonoida, grupa jedinjenja sa velikim terapeutskim potencijalom, i prisutni su u prirodnim izvorima kao što su voće, začinsko bilje i čajevi. Za njih je utvrđeno da poseduju antioksidativni, antibakterijski, antimalarijski, antiviralni, antihiperglikemijski i antitumorski efekat. Cilj ovog projekta je ispitivanje grupe od trinaest novosintetisanih derivata antrahinona, i analiza njihovih molekularnih mehanizama. Ova jedinjenja su dizajnirana sa ciljem da im se poboljša aktivnost i specifičnost u odnosu na prirodne derivate koji su trenutno u upotrebi. Devet jedinjenja ove grupe predstavljaju antrahinonske tiosemikarbazone, dok su četiri halkonski antrahinoni. Prvi korak u istraživanju je predstavljalo određivanje potencijalnog antitumorskog dejstva derivata antrahinona prema sedam malignih ćelijskih linija poreklom iz različitih tipova kancera. Selektivnost u nivou toksičnog dejstva određena je uz pomoć eksperimenata na uspostavljenoj liniji normalnih humanih ćelija..."

"Naturally occuring anthraquinones, an important class of quinone compounds, are numerous in plants, moss, lichen and other organizms. These quinol compounds posses laxative, antibiotic, antiinflamatory, antipyretic and antiviral properties, and their potential for cancer treatment and inhibition of proliferation and metastasis of malignant cells is what makes them one of the most interesting classes of compounds in cancer drug development field. Their mechanism of action includes involvement in the metabolic processes, oxidativve phosporylation, DNA and RNA intercalation and inhibition of telomerase and topoisomerase II. The most well-known compounds belonging to this class are anthracyclines, anthraquinone antibiotics. Anthracyclines, such as doxorubicin and daunorubicin, are widely used in treatment of cancer, even though they are highly cardiotoxic. Thiosemicarbazones are a class of imine derivatives which posses in their molecule an atom of sulfur. They are characterized by an exceptional ability to chelate metal ions. They have antiviral, antibacterial, antifungal and cytotoxic and antiproliferative activities. Chalcones are flavonoid and isoflavonoid precursors, a class of compounds with a significant therapeutic potential, and they can be found in natural sources like fruit, herbs and teas. It was previously determined that they can have anti-oxidative, antibacterial, antimalarial, antiviral, antihyperglycemic and antitumor effects. The aim of this research is to investigate a group of thirteen newly synthesized anthraquinone derivatives, and to analyze their mechanisms of action. These compounds were designed in a way that aims for increased activity and specificity compared to the currently used natural derivatives. Nine of the thirteen compounds are anthraquinonethiosemicarbazone derivatives, and another four belong to the subgroup of anthraquinonechalcones..."

"Dugotrajna restrikcija hrane produžava životni vek i odlaže pojavu mnogih bolesti koje se javljaju sa starenjem. Brojni literaturni podaci ukazuju da kod životinja kojima je unos hrane smanjen izostaje karakterističan starosno-zavistan pad u kognitivnim funkcijama, međutim, mehanizam ovakvog neuroprotektivnog dejstva restrikcije hrane nije u potpunosti razjašnjen. U isto vreme, kod životinja na dugotrajnoj restrikciji hrane se povećava nivo kortikosterona u plazmi što ukazuje da ovaj tretman deluje kao blagi stresor. Do sada nije ispitivano do kakvih promena u signalnom putu glukokortikoida dovodi smanjeni unos hrane tokom starenja u mozgu. Centralno polje istraživanja procesa starenja neizbežno podrazumeva ispitivanje promena do kojih dolazi u korteksu i hipokampusu, strukturama mozga koje su ključne za kognitivne funkcije. Sa druge strane, iste strukture učestvuju u regulaciji HHA ose kao važni regioni delovanja negativne povratne sprege. Cilj doktorske disertacije je da se ispita uloga signalnog puta glukokortikoida u korteksu i hipokampusu pacova tokom starenja i pod uticajem dugotrajne restrikcije hrane. Eksperimentalne životinje (mužjaci pacova soja Wistar) starosti 6 meseci su podeljene u dve grupe. Prva grupa, označena kao ad libitum (AL), je imala neograničen pristup hrani, dok je druga grupa (označena kao DR) podvrgnuta režimu redukovane ishrane koji je podrazumevao dobijanje 100% dnevnog unosa hrane AL životinja svakog drugog dana. Životinje su analizirane kada su dostigle starost od 18 i 24 meseca. Životinje stare 6 meseci su predstavljale kontrolnu grupu. Glukokortikoidna signalizacija u ispitivanim strukturama je praćena na prereceptorskom nivou, kao i na nivou ekspresije i aktivacije glukokortikoidnog receptora primenom imunoesej, imunoblot i PCR metoda, kao i imunohistohemijske analize. Rezultati doktorske disertacije pokazuju da tokom starenja dolazi do povećanja koncentracije kortikosterona u korteksu pacova, dok dugotrajna restrikcija hrane povećava nivo kortikosterona u obe ispitivane strukture. Utvrđeno je da nivo ključnog enzima koji u moždanom tkivu reguliše dostupnost kortikosterona za receptore, 11β-HSD1, raste u hipokampusu pacova koji imaju neograničen pristup hrani. Tretman dugotrajnom restrikcijom hrane dovodi do povećanja nivoa 11β-HSD1 u korteksu, dok u hipokampusu izostaje efekat na nivo ovog enzima..."

"Moderate restriction in food intake (dietary restriction, DR) extends the life-span and delays the onset of many age-related diseases. In addition, food-restricted animals exhibit attenuated cognitive deficits during aging as they perform better in learning and memory tasks than their ad libitum fed counterparts. At the same time, the animals on chronic food restriction have elevated levels of plasma corticosterone, which implies that this treatment could be considered as a mild stressor. So far, there are no literature data regarding the effects of food restriction on glucocorticoid signaling in the brain during aging and the mechanisms by which DR exhibits its neuroprotective effects are poorly understood. Two brain regions of interest are cortex and hippocampus, regions particularly prone to age-related changes. The same regions are also involved in cognition and regulation of the hypothalamic–pituitary–adrenal (HPA) axis activity. The aim of the present study was to evaluate the effect of long-term food restriction on glucocorticoid signaling pathway in the cortex and hippocampus of rats during aging. Experimental animals (male Wistar rats, 6 months old) were divided into two groups. The AL group was fed ad libitum, whereas the food restricted group (DR) received 100% of the mean daily intake of the AL animals every other day. The animals were examined at the age of 18 and 24 months. Six-month-old animals were used as a control. Glucocorticoid signaling in specific brain regions was examined at the pre-receptor level, as well as regarding the level of expression and glucocorticoid receptor activity by using immunoassays, Western blot, PCR and immunohistochemistry. The results of this study demonstrate an age-related increase in cortical corticosterone concentration. The increase in the hormone level was further detected in DR animals, in both brain regions examined. However, 11β-HSD1, a key enzyme in brain tissue that regulates the availability of corticosterone to its receptors, was increased only in the hippocampi of AL rats and in the cortex of rats subjected to the long-term food restriction. The most pronounced changes in the level of glucocorticoid receptor during aging were observed in the hippocampi of AL animals..."

"Glavni cilj ovog rada je utvrivanje ukupnog broja balkanskih endemicnih taksona ranga vrste i podvrste na teritoriji Crne Gore. Terenskim istraživanjima, i pregledom obimne literaturne grae i herbarskih zbirki utvreno je da u Crnoj Gori rastu 372 balkanska endemicna taksona. Podaci koji obuhvataju rasprostranjenje, ekološke karakteristike kao i literaturne i herbarske izvore za svaki pojedinacan takson inkorporirani su u bazu podataka Microsoft Excel koja broji 7215 zapisa. Popisani su svi lokaliteti na kojima je svaki pojedinacan takson bio konstatovan. Uraene su areal karte sa UTM koordinatama 10x10 km na kojima je prikazano rasprostranjenje svakog pojedinacnog taksona na teritoriji Crne Gore. Analizom opšteg rasprostranjenja tj. rasprostranjenja na Balkanskom poluostrvu, za svaki takson je odreen florni elemenat, areal podgrupa i areal grupa. Prikazane su i ekološke karakteristike endemicnih taksona koje su podrazumijevale utvrivanje pripadnosti odgovarajucoj životnoj formi, tipova staništa koje naseljava dati takson, dijapazona nadmorskih visina i tipova geološke podloge. U slucajevima preuzimanja literaturnih podataka iz fitocenoloških radova unošene su i informacije o ekspoziciji i nagibu terena staništa, te stepenu prisutnosti endemicnih taksona u odreenoj asocijaciji. Taksonomska analiza balkanske endemicne flore Crne Gore pokazala je da su najbogatije familije Asteraceae, Caryophyllaceae, Campanulaceae, Fabaceae i Lamiaceae, dok cak 13 familija ima predstavnika u jednom endemicnom taksonu. U okviru najbrojnije familije Asteraceae je i najbrojniji rod Hieracium sa 71 taksonom, slijede rodovi Dianthus, Edraianthus i Campanula. Rodovi Stachys, Cerastium i Alchemilla su zastupljeni sa istim brojem endemicnih vrsta i podvrsta. Zanimljivo je da cak 80 rodova ima po jednog endemicnog predstavnika. Horološka struktura balkanskih biljnih endemita Crne Gore ukazuje da gotovo dvije trecine endemicnih taksona cine orofite koje pripadaju dvjema horološkim grupama: južno evropsko planinskoj (146 taksona ili 39,2%) i srednje evropskoj planinskoj (99 taksona ili 26,6%)..."

"The main objective of this study is to determine the total number of the Balkan endemic taxa of species and subspecies rank on the territory of Montenegro. Field research and extensive literature and herbarium collection review has found that there are 372 Balkan endemic taxa in Montenegro. The data which include distribution, ecological characteristics, as well as literature and herbarium sources for each individual taxon have been incorporated in a Microsoft Excel database which includes 7215 records. The study lists all sites in which individual taxa were identified. Areal maps with UTM coordinates 10x10 km have been made, representing the distribution of each individual taxon on the territory of Montenegro. Analysis of the general distribution, i.e. the distribution on the Balkan Peninsula has defined the floral element, areal subgroup and areal group for each taxon. Ecological characteristics of endemic taxa have also been stated, which implied determining the affiliation to appropriate life form, habitat types inhabited by the given taxon, range of altitudes and geological substrate types. When citing literature data from phytocoenological papers, information have been entered on habitat exposure and slope, as well as on endemic taxa presence in a certain association. Taxonomic analysis of the Balkan endemic flora in Montenegro has shown that Asteraceae, Caryophyllaceae, Campanulaceae, Fabaceae and Lamiaceae are the richest families, while as many as 13 families have a representative in one endemic taxon. The most numerous Asteraceae family includes the largest Hieracium genus with 71 taxa, followed by Dianthus, Edraianthus and Campanula genera. Stachys, Cerastium and Alchemilla genera are represented with an equal number of endemic species and subspecies. It is interesting to note that as many as 80 genera have one endemic representative. Chorological structure of the Balkan endemic plants in Montenegro shows that almost two thirds of endemic taxa are orophytes that belong to two chorological groups: south European mountain (146 taxa or 39.2%) and central European mountain group (99 taxa or 26.6%)..."

"U ovom radu analizirana je fitohemijska i genetiţka varijabilnost i diferencijacija sedam autohtonih populacija Pinus nigra u Srbiji koje pripadaju razliţitim infraspecijskim taksonima (ssp. nigra, var. gocensis, ssp. pallasiana i var. banatica). U dvogodišnjim ţetinama 195 jedinki iz sedam populacija odreŤen je sadrţaj i varijabilnost n-alkana i terpena. Kutikularne voskove ţetina istraţivanih populacija crnog bora odlikuje serija nalkana od C16 do C33, osim u populacijama opisanim kao ssp. nigra u kojima je detektovana serija od C18 do C33. Najzastupljeniji su n-alkani sa neparnim brojem C atoma: C23, C25, C27 i C29 (proseţni sadrţaj 10.3, 16.5, 15.1 i 10.7%, respektivno). U etarskim uljima ţetina utvrŤeno je ukupno 75 komponenti, od koji je 58 identifikovano. Dominantne komponente su α-pinen (43.6%) i germakren D (29.8%), koje zajedno ţine 73.4% mase ulja. Multivariacione statistiţke analize (PCA, CDA i HCA) koriššenih fitohemijskih markera su, generalno, pokazale tendenciju formiranja tri grupe populacija (nigra, pallasiana i banatica). Na osnovu varijabilnosti terpena, populacije Priboj i Goţ (determinisane kao var. gocensis) pokazale su umerenu tendenciju odvajanja od prve grupe (ssp. nigra), dok je prema sastavu n-alkana populacija Priboj pokazala još vešu tendenciju odvajanja. Pretpostavljeno je da takson gocensis predstavlja tranzicionu formu izmeŤu taksona nigra na zapadu i pallasiana na jugoistoku Srbije. U cilju odreŤivanja genetiţkog diverziteta i diferencijacije sedam istraţivanih populacija P. nigra iz Srbije, testirano je 114 jedinki pomošu jedarnih (nuDNK), hloroplastnih (cpDNK) i mitohondrijalnih (mtDNK) markera koji imaju bi-parentalno, paternalno i maternalno nasleŤivanje, respektivno, kao i razliţitu brzinu evolucije. Zbog nedostatka jedarnih mikrosatelita (nuSSRs) specijalno razvijenih za P. nigra, uraŤena je inter-specijska PCR amplifikacija tri EST-SSRs razvijenih za P. taeda. Iako su dva ESTSSR lokusa uspešno PCR-amplifikovana u našim uzorcima, utvrŤeno je odsustvo varijabilnosti zbog ţega su iskljuţeni iz dalje analize. Od pet testiranih cpDNK SSRs, tri su uspešno PCR-amplifikovana u našim uzorcima, sa 22 detektovana alela koji formiraju 38 haplotipova. Kao što je i oţekivano, s obzirom na intenzivan protok gena posredstvom polena kod ţetinara, utvrŤen je veoma visok nivo cpDNK diverziteta (HT = 0.949) i mali stepen diferencijacije (Fst = 0.017, p = 0.108, Gst = 0.024, Rst = 0.066)..."

"In this work phytochemical and genetic variability and differentiation of seven native populations belonging to different infraspecific taxa of Pinus nigra (ssp. nigra, var. gocensis, ssp. pallasiana i var. banatica) in Serbia were analyzed. In the needles of 195 trees from seven populations, composition and variability of n-alkanes and terpenes were determined. The size of the n-alkanes found in the needle cuticular waxes of the black pine populations investigated ranged from C16 to C33, with the exception of that of the subspecies nigra, which ranged from C18 to C33. The most abundant n-alkanes were the four odd-numbered n-alkanes C23, C25, C27, and C29 (mean contents of 10.3, 16.5, 15.1, and 10.7%, respectively). In the needle essential oils a total of 58 individual components out of the 75 compounds detected could be identified. The major components of the oils were α-pinene (43.6%) i germakrene D (29.8%), comprising together in average 73.4% of the essential oil composition. Multivariate statistical analysis (PCA, CDA, and HCA) of used phytochemical markers showed, in general, a tendency to the formation of three populations groups (nigra, pallasiana, and banatica). Based on the terpene variability, populations Priboj and Goţ, determined as var. gocensis, showed a moderate tendency of separation from the first group (ssp. nigra), while based on n-alkane composition, population Priboj showed even a greater tendency of separation. It was assumed that taxon gocensis might be a transitional form between taxa nigra occurring in the west and pallasiana growing in the southeast of Serbia. We screened 114 trees from seven studied P. nigra populations from Serbia with nuclear (nrDNA), chloroplast (cpDNA) and mitochondrial (mtDNA) markers which have bi-parental, paternal and maternal inheritance, respectively, and different evolutionary rates to infer levels of genetic diversity and structuring within studied area. Due to the lack of nuclear microsatellites (nuSSRs) specifically developed for P. nigra, we employed three EST-SSRs developed for P. taeda for cross-species amplification in P. nigra. Although two EST-SSR loci were successfuly PCR-amplified in our samples, they were invariable and discarded from further analyses..."

"Nelinearne i napredne statističke metode, pored linearnih metoda, zauzimaju sve značajnije mesto u analizi fizioloških signala, posebno u svetlu nelinearnog i haotičnog ponašanja bioloških sistema. Stoga je zajednička upotreba Higučijeve fraktalne dimenzije i analize nezavisnih komponentata (ICA), značajan i nov pristup u analizi signala a posebno u analizi aktivnosti jednog neurona. Najprepoznatljiviji tip spontane bioelektrične aktivnosti neurona beskičmenjaka i kičmenjaka jeste pojava akcionih potencijala u paketićima. U radu je po prvi put primenjen, jedinstven i inovativan pristup u razdvajanju komponenata spontane bioelektrične aktivnosti Br neurona vinogradskog puža i to na akcione potencijale (AP), intervale između akcionih potencijala (ISI) i tihe intervale bez aktivnosti (IBI) uz pomoć Higučijeve fraktalne dimenzije i aproksimacije Gausovim funkcijama. Taj metodološki pristup je omogućio praćenje uticaja konstantnog magnetnog polja i uabaina inhibitora Na+/K+ pumpe na promene u kompleksnosti spontane bioelektrične aktivnosti Br neurona. Sa druge strane, po prvi put je testirana upotreba ICA metode u različitim eksperimentalnim uslovima po AP, ISI i IBI komponentama spontane bioelektrične aktivnosti. Na taj način, u ovom radu demonstrirana je snaga zajedničke upotrebe navedenih metoda uz predlog da se proširi njihova upotreba za potrebe analize spontano aktivnih neurona različitih vrsta u fiziološkim i patološkim stanjima."

"Nonlinear and advanced statistical methods, in addition to linear methods, occupy a prominent place in the analysis of physiological signals, especially in light of the non-linear and chaotic behavior of biological systems. Therefore, the use of Higuchi fractal dimension and independent component analysis (ICA), reperesents a new approach to signal analysis, especially regarding the activities of one neuron. The most recognizable type of spontaneous bioelectric activity in neurons of invertebrates as well as vertebrates is the appearance of bursting activity. This study presents a unique and innovative approach to the separation of the components of spontaneous bioelectric activity of the garden snail Br neuron - action potential (AP), interspike interval (ISI) and interburst interval (IBI), by using Higuchi’s fractal dimension and Gaussian fitting functions. This methodological approach allows monitoring of the effect of static magnetic field and the inhibitor of the Na+/K+ pump, ouabain, on the changes in the complexity of the spontaneous bioelectric activity of the Br neuron. On the other hand, for the first time ICA method was tested in different experimental conditions on AP, ISI and IBI components of spontaneous bioelectric activity. This study demonstrates the power of the common use of the above mentioned methods and proposes to extend their use for the purpose of analyzing spontaneously active neurons of different species in physiological and patological conditions."

Brown adipose tissue (BAT), as energy dissipating tissue, emerged as possible target for antiobesity therapy. Thyroid hormones play an important role in regulation of temperature homeostasis and energy metabolism and they are involved in regulation of BAT activity. Thus, continuous crosstalk between thyroid gland/hormones and adipose tissue may be important for body weight control. While the importance of thyroid hormones for proper BAT function is well known, the influence of systemic hyperthyroidism on BAT activity is not yet fully understood. This dissertation started from two directly confronted premises concerning the place of BAT in thyroid thermogenesis. The first of them implies that BAT thermogenic function in systemic hyperthyroidism is suppressed while according to the other one BAT is effectory organ of thyroid thermogenesis. Therefore, this dissertation aims to investigate the effects of experimentally induced systemic hyperthyroidism on structural remodelling and thermogenic capacity of BAT in order to shed more light on regulatory mechanisms controlling its function. Also, the aim was to analyse differences, if any, between effects of two thyroid hormones, T3 and T4. The experiment was performed on a total of 18 male Wistar rats, kept under standard laboratory conditions, at the room temperature. Animals from the first experimental group received T3 in dose of 200 =g/kg b.w., . while animals from the second experimental group received T4 in dose of 300 =g/kg b.w., ., once a day, during five days. Rats from the third group were treated with vehicle only, according to the same schedule. Histological and histochemical analyses of BAT were performed at the level of light microscopy using 5 =m thick paraffin sections of routinely processed tissue stained with hematoxylineosine, PAS, Bodian and Novelli methods. For detection of apoptosis, propidium iodide method was used...",
"Povećana telesna težina i gojaznost prouzrokovane disbalansom izmeñu unosa energije i njenog trošenja, predstavljaju rastući zdravstveni problem u svetu. Mrko masno tkivo (MMT), kao tkivo koje rasipa energiju, postaje moguće ciljno tkivo za lečenje gojaznosti. Tiroidni hormoni imaju važnu ulogu u regulaciji temperaturne homeostaze i energetskog metabolizma i uključeni su u regulaciju aktivnosti MMT. Prema tome, postojanje stalne komunikacije izmeñu tiroidne žlezde/tiroidnih hormona i masnog tkiva može biti značajno za kontrolisanje telesne težine. I dok je značaj tiroidnih hormona za ispravno funkcionisanje MMT dobro poznato, uticaj sistemskog hipertiroidizma na njegovu aktivnost još uvek nije u potpunosti shvaćen. Ova disertacija bazirana je na dve meñusobno suprotstavljene polazne pretpostavke koje se tiču mesta MMT u tiroidnoj termogenezi. Prva podrazumeva supresiju termogene funkcije MMT u sistemskom hipertiroidizmu, dok prema drugoj MMT predstavlja efektorski organ tiroidne termogeneze. Prema tome, cilj ove disertacije bio je ispitivanje efekata eksperimentalno indukovanog sistemskog hipertireoidizma na strukturno remodeliranje i termogeni kapacitet MMT, kako bi se doprinelo razjašnjavanju mehanizama njegove regulacije. Isto tako, cilj je bio analizirati razlike, ako ih ima, u efektima dva glavna tiroidna hormona, T3 i T4. Eksperiment je izveden na ukupno 18 mužjaka Wistar pacova, držanih pod standardnim laboratorijskim uslovima, na sobnoj temperaturi. Životinje iz prve eksperimentalne grupe primale su T3 u dozi od 200 =g/kg b.w., . dok su životinje iz druge eksperimentalne grupe primale T4 u dozi 300 =g/kg b.w., ., jednom dnevno, tokom pet dana. Pacovi iz treće grupe bili su tretirani samo prenosnikom, prema istom rasporedu. Histološka i histohemijska analiza MMT obavljena je na nivou svetlosne mikroskopije, korišćenjem 5 =m parafinskih preseka rutinski sprovedenog tkiva, obojenih hematoksilinomeozinom, PAS metodom, Bodian metodom i Novelli metodom..."

"Према извештају публикованом од стране Института за Медицину у Сједињеном Америчким Државама, стопа превремено рођене а самим тим ризичне деце је повeћана за више од 30 процената у последње две декаде. У Европи 5-10% деце рађа се пре времена. Проспективно и лонгитидунално праћење ове популације, показује да та деца у каснијем узрасту имају неуроразвојне поремећаjе у знатно већој мери од опште популације. У овом истраживању праћене су две групе деце, са церебралном парализом и интракранијалном хеморагијом првог и другог степена. Константовано је да последњих 40 година нема значајних промена у погледу учесталости церебралне парализе и да је њена превенција за сада недовољно ефикасна. Учесталост у свету варира од 0,5 до 6% (промила), у просеку се креће 2 до 3% на 1000 рођених, 2 до 3 детета су су са церебралном парализом. Интракранијална крварења првог и другог степена често се називају и тзв. некомпликована крварења и ретко узрокују трајне моторичке и когнитивне дефиците, док према неким ауторима 30% ове деце испољава неки неуроразвојни поремећај. Ово истраживање је обухватило проспективно праћење говорно-језичког развоја 62–је новорођенчади до навршене треће године живота.

"According to the report published by the Institute of Medicine (U.S), the rate of prematurely born children, therefore children born with riscs, has increased more than 30 percent in the last two decades. In Europe, 5-10% of children are born prematurely. Prospective and longitudinal study of this population shows that number of preterm children with neurodevelopmental disorders at later age is significantly greater than in the general population. This study observed two groups of children, children with cerebral palsy and children with intracranial hemorrhage of first and second degree. It has been concluded that in the last 40 years, there has been no significant changes in the incidence of cerebral palsy and that its prevention is not efficient enough, for now. The incidence in the world ranges from 0.5 to 6% (per thousand), on average from 2 to 3% per 1000 births, 2 to 3 children are born with cerebral palsy. Intracranial hemorrhage of first and second degree, often referred to as uncomplicated hemorrhage, rarely causes permanent motor and cognitive deficits, while according to some authors, 30% of these children manifest some neurodevelopmental disorders. This study included a prospective followup of speech and language development of 62 newborns up to the age of three. All of the children were patients of the Special Hospital for Cerebral Palsy and Developmental Neurology in Belgrade. Half of the sample (31) consisted of infants who were diagnosed with intracranial hemorrhage of first and second degree I/II. These children came to our institution with established diagnosis (ultrasound), and they were referred for psychomotor development monitoring. The other half of the sample (31) were children born with highrisk, they were administered as cerebrally compromised, or children with a delay in psychomotor development, all of these children (31) were diagnosed with cerebral palsy until their third year..."

"Osnovna uloga mrkog masnog tkiva je održanje tjelesne temperature i održanje energetske homeostaze organizma. Izlaganje hladnoći, a i povećan unos hrane, dovodi do stimulacije, proliferacije i diferencijacije mrkih adipocita, što je praćeno remodeliranjem mitohondrija, termogenih organela mrkih adipocita. U okviru strukturnog remodeliranja mitohondrije pokazuju širok dijapazon morfoloških promjena (broj mitohondrija u ćeliji, srednji dijametar, fuzija i fisija mitohondrija, volumenska gustina kristi) što je povezano sa prisustvom pojedinih kompleksa elektron transportnog lanca, ATP sintaze, familije UCP proteina, posebno UCP1, a i drugih proteina unutrašnje membrane mitohondrija. Kalcijum igra veoma važnu ulogu u termogenezi, njegova koncentracija u citoplazmi i organelama mrkih adipocita je hormonski regulisana, prije svega noradrenalinom. Mitohondrije, s jedne strane, imaju važnu ulogu u oblikovanju signalnih puteva kalcijuma, a kalcijum, s druge strane, u fiziološkim koncentracijama stimuliše mitohondrijalni metabolizam i povećava produkciju energije, dok u visokim koncentracijama indukuje apoptozu. Insulin je jedan od glavnih modulatora termogene funkcije mrkih adipocita, gdje stimuliše sintezu i deponovanje lipida u mrkim adipocitima, proliferaciju mrkih adipocita, angiogenezu i vazodilataciju. Pokazano je da insulin utiče na aktivnost elektron transportnog lanca, a i da mitohondrije pojačavaju insulinsku osjetljivost putem redoks regulacije proteina tirozin kinaze i insulinskog receptora. Cilj ove doktorske disertacije je rasvjetljavanje kako kalcijum, s jedne strane, a insulin, s druge strane, utiču na molekulske mehanizme koje su uključene u strukturno remodeliranje mitohondrija mrkih adipocita pacova. U eksperimentu su korišćeni Wistar pacovi, starosti dva mjeseca. U eksperimentu sa Ca-SANDOZ, životinje su podijeljene u dve grupe, jedna je pila Ca-SANDOZ rastvoren u vodi, a druga, kontrolna, česmensku vodu, tri dana. U eksperimentu sa insulinom, pacovi su podijeljeni u šest grupa, četiri grupe su primale nisku (0.4 IU) ili visoku (4 IU) dozu insulina i to jedan (akutno) ili tri dana (hronično). Ostale dvije grupe, kontrolne, su primale fiziološki rastvor akutno ili hronično. Trećeg dana tretmana Ca-SANDOZ, odnosno tri sata poslije posljednjeg tretmana insulinom, životinje su žrtvovane dekapitacijom, a interskapularni depo BAT je izolovan i pripremljen za biohemijske, mikroskopske i molekularno-biološke analize, i za izolaciju mitohondrijalnih frakcija.

"Essential role of brown adipose tissue is maintaining body temperature and energy homeostasis of organism. Exposure to cold and increased diet intake lead to stimulation, proliferation and differentiation of brown adipocytes, what is followed by remodeling of mitochondria, thermogenic organelles of brown adipocytes. In the context of structural remodeling, mitochondria show wide repertoire of morphological changes (e.g. mitochondria number in cell, mean diameter, fusion and fission of mitochondria, volume density of mitochondrial cristae) what is connected with abundance of components of electron transport chain (ETC), ATP synthase, UCP proteins - especially UCP1 protein, and other proteins of inner mitochondrial membrane. Calcium plays important role in thermogenesis, and its concentration in cytosol and organelles of brown adipocytes is hormone regulated, particularly by noradrenaline. Mitochondria has essential role in shaping calcium signaling pathways, and calcium, on other hand, stimulates mitochondrial metabolism and increases energy production, but in high concentrations induces apoptosis. Insulin is one of major modulators of thermogenic function of brown adipocytes, and stimulates synthesis and storage of lipids in brown adipocytes, proliferation of brown adipocytes, angiogenesis and vasodilatation. It is showed that insulin has effect on electron transport chain activity, but also mitochondria enhances insulin sensitivity via redox regulation of tyrosine kinases and insulin receptor. The aim of this doctoral dissertation is elucidation how calcium and insulin effect on molecular mechanisms involved in structural remodeling of mitochondria of rat brown adipocytes. Two-month-old male Wistar rats were used. In Ca-SANDOZ study, they were divided into two groups - Ca-SANDOZ drinking or tap water drinking for three days. In insulin experiment, rats were divided into six groups, where four groups treated with low (0.4 IU) or high (4 IU) dose of insulin, for one (acutely) or three (chronically) days. Another two groups served as control, treated with 0.9% saline solution for one or three days. On third day of Ca-SANDOZ treatment, or three hours after last administration of insulin, they were sacrificed by decapitation, and interscapular portion of BAT was isolated and prepared for biochemical, microscopic and molecular biology analyses, also for isolation of mitochondria-enriched BAT fraction. BAT and mitochondria-enriched fraction were analyzed by Western blot analysis, imunohistochemical, immunofluorescent, immunogold, ultrastructural and stereological analyses. Also, ATP synthase activity was measured..."

"Cilj ovog rada je utvrđivanje ukupnog broja taksona u rangu vrsta i podvrsta u flori dela severozapadne Srbije i Šumadije. Na osnovu višegodišnjih terenskih istraživanja i sagledavanja postojeće literaturne građe, formirana je obimna herbarska zbirka i prikupljena velika količina florističkih i ekoloških informacija, uobličenih u vidu baze podataka, koji govore o strukturnim karakteristikama i zakonitostima formiranja flore na pomenutom području. Sistematskim terenskim istraživanjima i na osnovu malobrojnih publikovanih referenci koje se odnose na florističku i fitocenološku literaturu utvrđeno je da floru severozapadne Srbije i Šumadije izgrađuje 1333 taksona u rangu vrste i podvrste svrstanih u 535 rodova i 115 familija. Rezultati ovog rada predstavljaju listu u kojoj je predstavljen svaki pojedinačni takson zabeležen u flori severozapadne Srbije i Šumadije uz navođenje svih lokaliteta na kojima je na navedenom području takson konstatovan. U odnosu na izvore podataka, tip rasprostranjenja i ekološke karakteristike svakog pojedinačnog taksona, prikazan je kritički osvrt na kvalitet i pouzdanost literaturnih podataka koji se odnose na floru ovog područja. Na osnovu opšteg rasprostranjenja, za svaki pojedinačni takson određen je florni element i pripadnost određenom areal tipu i areal grupi. Za svaki takson je određena detaljna životna forma, gde su prikazane i njegove ekološke karakteristike, koje podrazumevaju detaljne karakteristike staništa, dijapazone nadmorskih visina i tipove geološke podloge i vegetacije koje naseljava taj takson na istraživanom području.

"The objective of this research was to determine the total number of taxa at the level of species and subspecies in the flora of part of north-western Serbia and Šumadija. Based on field and literature surveys conducted over a number of years, an extensive herbarium collection was made and vast amounts of floristic and ecological data were collected and organised in a database on the structural characteristics and patterns of formation of the flora in the study area. As determined by systematic field surveys and based on very few published references available on floristic and phytocoenological data, the flora of north-western Serbia and Šumadija includes 1333 taxa at the level of species and subspecies classified into 535 genera and 115 families. Research results are reported in the form of a list presenting each individual taxon recorded in the flora of north-western Serbia and Šumadija and indicating its locations in the area surveyed. In terms of sources of information and type of distribution and ecological characteristics of each individual taxon, a critical review of the quality and reliability of literature data on the flora of this region is given. Based on their general distribution, the taxa were classified into floral elements, range types and range groups. Detailed life forms were determined for all taxa, with data provided on their ecological characteristics, including detailed habitat characteristics, altitude ranges and types of geological substrate and vegetation inhabited by each individual taxon in the study area. Among the taxa, flowering plants predominate with 1302 taxa, including 1070 species and subspecies that belong to the class Dicotyledones, making up 94 families and 418 genera; and flowering plants of the class Monocotyledones comprising 12 families, 100 genera and 229 species and subspecies. Pteridophyta are represented by 8 families, 11 genera and 26 taxa. Gymnospermae embrace only 2 families, 6 genera and 8 species..."

"Dijabetes tipa 1 (DT1) je autoimunsko inflamatorno oboljenje koje se razvija kao posledica uništavanja ćelija pankreasa posredstvom autoagresivnih ćelija i njihovih pro-inflamatornih medijatora. Glavno obeležje DT1 je insulitis – infiltracija pankreasa populacijama imunskih ćelija. Makrofagi se smatraju prvim ćelijama koje infiltriraju pankreasna ostrvca i imaju važnu ulogu u aktivaciji autoreaktivnih T ćelija. Smatra se da klasiĉno aktivisani M1 makrofagi doprinose razvoju i progresiji bolesti, dok alternativno aktivisani M2 makrofagi uĉestvuju u njenom spreĉavanju. B limfociti imaju ulogu u produkciji autoantitela, dok su T (CD4+ i CD8+) ćelije jedne od glavnih efektorskih ćelija koje su ukljuĉene u ubijanje ćelija. Citokini koje sekretuju razliĉite imunske ćelije, ukljuĉujući makrofage i T ćelije, mogu da regulišu u kom smeru će se razviti imunski odgovor: ka Th1 (engl. T helper) dijabetogenom odgovoru ili Th2 protektivnom odgovoru. Aktivisani makrofagi, pomoćniĉki i citotoksiĉni T limfociti, kao i sekretovani pro-inflamatorni medijatori, sinergistiĉki uĉestvuju u razaranju ćelija i razliĉitim mehanizmima pokreću apoptozu ovih ćelija, što rezultuje nastankom autoimunskog DT1. Kako terapija DT1 uglavnom podrazumeva primenu egzogenog insulina, sve više se istražuju novi terapijski pristupi koji bi spreĉili ili usporili pokrenuti autoimunski odgovor. Ugljen monoksid (CO) je potencijalni kandidat za tretman autoimunskih bolesti, kao što je DT1, zbog svojih anti-inflamatornih i antiapoptotskih karakteristika. CO nastaje u organizmu delovanjem enzima hem oksigenaze (HO) koja razgraĊuje hem do CO, biliverdina i gvožĊa. Uprkos izuzetnoj toksiĉnosti u visokim koncentracijama, primenjen u niskim koncentracijama egzogeni CO ima terapijski potencijal kao anti-inflamatorni agens koji moduliše brojna imunoinflamatorna stanja. Sintetisana metalo-organska jedinjenja koja oslobaĊaju CO (CORM engl. Carbon Monoxide Releasnig Molecule) predstavljaju grupu jedinjenja sposobnih da otpuštaju CO na kontrolisani naĉin u ćelijskim sistemima. Jedno od brojnih CORM je i CORM-A1 koji se izdvaja od ostalih jedinjenja jer je rastvorljiv u vodi, ne sadrži prelazne metale u svojoj strukturi i vreme poluživota ovog jedinjenja u fiziološkim uslovima je 21,4 minut..."

"Type 1 diabetes (T1D), an autoimmune inflammatory disorder, develops as a consequence of pancreatic beta cell destruction mediated by various pro-inflammatory mediators. The major hallmark of T1D is infiltration of different populations of immune cells into pancreas called insulitis. Macrophages are the first cell types to infiltrate the pancreatic islets and play essential role in the development and activation of autoreactive T cells. Classically activated M1 macrophages are involved in disease development and progression, while alternatively activated M2 macrophages participate in disease suppression. B lymphocytes produce autoantibodies against pancreatic cell antigens, and T cells are known to play a crucial role as final effectors that kill cells. Cytokines secreted by various immune cells, including macrophages and T cells, may regulate the direction of the immune response toward helper T (Th) 1 cells, related to diabetes development, or Th2 response, which has protective role in T1D. Therefore, the activated macrophages, Th and cytotoxic T cells, as well as secreted proinflammatory mediators, act synergistically in destruction of cells through different mechanisms, resulting in development of autoimmune T1D. Since current T1D therapy mainly involves insulin replacement, constant efforts are being directed toward establishing novel therapeutic approaches that could inhibit or suppress autoimmune response. Carbon monoxide (CO) could be a potential therapeutic molecule for the treatment of autoimmune diseases, such as T1D, due to its anti-inflammatory and antiapoptotic abilities. CO, together with biliverdin and iron, arises endogenously from degradation of heme molecules by heme oxygenase (HO) enzyme. Despite extreme toxicity when given at high concentrations, exogenous CO delivered at low concentrations is showing therapeutic potential as an anti-inflammatory agent and, as such, can modulate numerous immunoinflammatory states. The carbon monoxidereleasing molecules (CORMs) represent a group of compounds capable of liberating controlled quantities of CO in the cellular systems..."

"Iz biblioteke cDNK semena heljde u srednjoj fazi sazrevanja prethodno je izolovana cDNK koja kodira atipičnu aspartičnu proteinazu (FeAPL1), a zatim i odgovarajući genomski fragment koji, osim kodirajuće sekvence, sadrži i 5’-regulatorni region u kome su uočeni cis-elementi koji mogu učestvovati u regulaciji ekspresije ovog gena pod uticajem faktora spoljašnje sredine i opredeljivati njegovu seme-specifičnu ekspresiju. U ovom radu uradjena je detaljna analiza ekspresije gena FeAPL1 po organima heljde- na nivou RNK upotrebom metoda RT-PCR i Real Time RT-PCR, a analizom Western blot na nivou proteina. Umnošci slabog intenziteta su uočeni u fazama sazrevanja semena do stadijuma 14 DAF, za kojima sledi naglo povećanje količine transkripta u stadijumu 14-17 DAF, nakon čega dolazi do smanjenja količine RNK. Profil ekspresije proteina prati profil ekspresije RNK. U listu, korenu, stablu i cvetu uočene su male količine transkripta, ali odgovarajući protein nije bio prisutan. Kako je kompjuterskom analizom predikovano više cis-aktivirajućih elemenata u promotorskom regionu gena za FeAPL1, njegova ekspresija je praćena i pod uticajem stresogenih faktora spoljašnje sredine (UV zračenje, mrak, mehanička povreda, suša, salicilna kiselina), ali značajne promene u ekspresiji nisu oučene ni u jednom ispitivanom slučaju. U cilju dobijanja proteina u količini pogodnoj za biohemijsku analizu i produkciju antitela, korišćeno je nekoliko ekspresionih sistema: E. coli, P. pastoris i kultura insekatskih ćelija. Zadovoljavajuća ekspresija dobijena je jedino pri upotrebi konstrukta rMBP-FeAPL1 u soju Rosetta-gami E. coli u kome je dobijen solubilan rekombinantni fuzioni proteina koji, nakon proteolitičke obrade, poseduje enzimsku aktivnost na pH 3,0, inhibiranu pepstatinom A. Rekombinantni protein, rFeAPL1-His6, od ~55 kDa, je eksprimiran u ćelijskoj liniji duvana BY-2 u kome je detektovana pepstatin A senzitivna enzimska aktivnost na pH 3,0 bez prethodne proteolitičke obrade. Veća molekulska masa u odnosu na predikovanu (46 kDa) ukazuje na verovatnu glikozilaciju proteina. Imunocitohemijskom analizom i analizom proteina protoplasta transformisanih BY-2 ćelija je utvrđeno da je FeAPL1 lokalizovan u ćelijskom zidu. Na osnovu dobijenih rezultata diskutovane su potencijalne funkcije proteinaze FeAPL1."

"Sistemska skleroza (SSc) je retka, heterogena, multisistemska, autoimuna bolest nepoznate etiologije sa varijabilnim kliničkim manifestacijama i nepredvidivim i često letalnim ishodom. Osnovne karakteristike ove bolesti su poremećaji u imunom sistemu i inflamacija, vaskulopatija, preterana produkcija komponenti vanćelijskog matriksa i progresivna fibroza kože i unutrašnjih organa. Pronalaženje novih biomarkera, koji bi omogućili bolje razumevanje patogeneze same bolesti, bilo bi od presudne važnosti za ranije uspostavljanje dijagnoze, bolju klasifikaciju pacijenata i primenu adekvatnije terapije. Stoga je u okviru ove teze ispitana asocijacija odabranih genetičkih varijanti u genima IRAK1 i miRNK-146a sa predispozicijom za razvoj SSc. Takođe, u cilju otkrivanja potencijalno novih i pouzdanih biomarkera praćena je ekspresija odabranih učesnika signalnih puteva JAK2/STAT3 i NF-kB, uključenih u proces inflamacije na sistemskom i proces fibroze na lokalnom nivou. Upotreba ćelijske terapije u lečenju oštećenja malih zglobova kod ovih pacijenata jedan je od potencijalno novih terapeutskih pristupa. Uprkos rastućem znanju i upotrebi mezenhimskih matičnih ćelija izolovanih iz adopoznog tkiva (aMMĆ) u ćelijskoj terapiji, veoma malo se zna kako gajenje ovih ćelija u laboratorijskim uslovima utiče na njihovu sposobnost samoobnove i potencijal za diferencijaciju u hondrocite. U cilju ispitivanja uticaja dužine gajenja ćelija na njihovu sposobnost samoobnove i potencijala za hondrogenu diferencijaciju, praćena je ekspresija gena markera matičnosti i hondrogene diferencijacije tokom in vitro kultivacije ovih ćelija. Studija asocijacije odabranih genetičkih varijanti, IRAK1 rs3027898 C>A i miRNK-146a rs2910164 G>C izvedena je na grupi od 102 SSc pacijenata i 66 zdravih ispitanika, direktnim sekvenciranjem po Sangeru. Relativna kvantifikaciona analiza ekspresije gena IL6, JAK2, STAT3, TLR7, TLR9, IRAK1 i miRNK-146a u mononuklearnim ćelijama periferne krvi (MNĆPK), izvršena je na podgrupi od 50 SSc pacijenata i 13 zdravih ispitanika, dok je ekspresiona analiza odabranih gena na lokalnom nivou izvedena na uzorcima tkiva kože, sa i bez fibrotičnih promena, poreklom iz 5 SSc pacijenata..."

"Systemic sclerosis (SSc) is a rare heterogeneous, multisystem, autoimmune disease with unknown etiology, characterized with variable clinical manifestations, and unpredictable and often lethal outcome. The basic mechanism of the disease appears to involve aberrant immune activation and inflammation, vasculopathy, overproduction of extracellular matrix proteins and progressive fibrosis of skin and internal organs. The identification of novel biomarkers will not only enable a better understanding of the disease pathogenesis, but also contribute to earlier establishment of diagnosis, better classification of patients, and the application of more appropriate therapy. Therefore, within this thesis, it was examined the association of selected genetic variants in the IRAK1 and miRNA-146a genes with the predisposition for development of SSc. In order to discover potentially novel and reliable biomarkers, the expression of selected participants of JAK2/STAT3 and NF-kB signal pathways, involved in the process of inflammation at the systemic and process of fibrosis at the local level, was examined. Stem cell therapy, is one of the potential new therapeutic approaches in the treatment of small-joint damage in SSc patients. Despite growing knowledge and utilization of adipose tissue-derived mesenchymal stem cell (aMSC) in therapy, very little known about how prolonged cultivation of these cells in laboratory conditions affects their ability for self-renewal and their potential for differentiation into functional chondrocytes. In order to investigate the influence of the long-term ex vivo cultivation on their potency and potential for chondrogenic diferrentiation, the expression of genes, markers of stemness, as well as markers for chondrogenic differentiation, during prolonged in vitro aMSC cultivation, was investigated. The association study between selected genetic variants, IRAK1 rs3027898 C> A and miRNA-146a rs2910164 G> C, and susceptibility to SSc was performed on a group of 102 SSc patients and 66 healthy subjects, by Sanger sequencing. Relative quantification analysis of the IL6, JAK2, STAT3, TLR7, TLR9, IRAK1 and miRNA-146a gene expressions in peripheral blood mononuclear cells, were performed on a subgroup of 50 SSc patients and 13 healthy subjects, while the expression analyzes of selected genes at the local level were performed on skin tissue samples, with and without fibrotic changes, originating from 5 SSc patients..."

"zahvata jadransko primorje i zaleđe. Postavlja se međutim, pitanje autohtonosti disjunktnih, kontinetalnih populacija u centralnom delu poluostrva, jer se ova termofilna vrsta od davnina koristi u lekovite svrhe, pa postoji mogućnost da su ove populacije antropogene, nastale nakon ledenog doba. Da bi se utvrdila starost i poreklo ovih disjunktnih populacja uzorkovano je 8 populacija za molekularna i 11 populacija za morfmetrijska ispitivanja. Za filogeografski deo istraživanja korišćene su sekvence dva intragenska spejsera hloroplasta 3’rps16-5’trnK and rpl32-trnL. Detektovano je sedam haplotipova koji nisu bili nasumično zastupljeni i poseduju filogeografsku strukturu, kao i visok ukupni genetički diverzitet (HT = 0.695) i genetičku diferencijaciju (GST = 0.682). Prema molekularnom satu i bajeziskoj analizi, razdvajanja predačkog genskog pula S. officinalis na dve linije desilo se u pliocenu (pre 3,267 mil. godina), što se podudara sa vremenom kada su centralni deo Balkana prekrile velike vodene površine i po svoj prilici podelile pretpostavljeni predački areal S. officinalis. Strukturirana, manje divergentna kontinetalno-primorska linija (CAL, Hd = 0.426, π = 0.00106) i divergentnija isključivo primorska linija (PAL, Hd = 0.403, π = 0.00257) nemaju odlike nedavne demografske ekspanzije i danas se preklapaju na jugoistočnom delu jadranskog primorja, koje je označeno kao glavni glacijalni refugijum S. officinalis. Četiri populacije iz kontinentalnog dela Balkanskog poluostrva, koje čine kontinetalnu podliniju CAL odlikuje skoro isključivo prisustvo posebnog haplotipa koji je redak u primorskoj podliniji CAL i odsutan u PAL. Zbog bliske genealoške veze ovog i ancestralnog haplotipa prema parsimonijskoj statističkoj analizi, kao i zbog specifičnih odlika kontinetalnih populacija, one su okarakterisane kao reliktne i refugijalne..."

"Within Balkan Peninsula, Salvia officinalis L. (Lamiaceae), common or Dalmatian sage, grows naturally along the Adriatic coast. However, the indigeneity of its distant continental disjunctions in Central Balkans is questionable, since this thermophilous species has been used in medicine for thousands of years and it may have been established post-glacially via anthropogenic mediation. To reveal the origin and the age of its disjunctions, 8 and 11 populations were sampled for molecular and morphometrical investigation, respectively. Sequences of two chloroplast intergenic spacers, 3’rps16-5’trnK and rpl32-trnL, were used for phylogeographic study. Seven haplotypes, non-randomly distributed in space were found as well as high total gene diversity (HT = 0.695) and genetic differentiation (GST = 0.682) showing a phylogeographic structure. According to the strict clock Bayesian analysis, the divergence of an ancient S. officinalis gene pool to two lineages was dated to the Pliocene (3.267 Ma), which coincides with the period when the vast water bodies covered the central part of the Peninsula and presumably divided the paleo-distribution of S. officinalis. A substructured and less diverse continental-Adriatic lineage (CAL, Hd = 0.426, π = 0.00106) and a more diverse, purely Adriatic lineage (PAL, Hd = 0.403, π = 0.00257) do not exhibit signs of recent demographic expansions and currently overlap on the southeastern Adriatic coast, a region designated as the main glacial refugium of S. officinalis. All four populations from the continental Balkans comprising the continental sub-lineage of CAL were almost fixed for a distinct haplotype which was rare in the Adriatic sub-lineage of CAL and absent in PAL. Given the close genealogical relation of that haplotype to the ancestral haplotype as inferred from a statistical parsimony analysis and other features of these populations, they were characterized as relict and refugial..."

"Somatska embriogeneza je indukovana iz apikalnih fragmenata lateralnih korenova spanaća (Spinacia oleracea L.) sorte \"Matador\", gajenih u uslovima in vitro na indukcionom Murashige & Skoog medijumu koji je sadržao 20 μM α-naftilsirćetnu kiselinu (NAA) i 5 μM giberelnu kiselinu (GA3). Embriogeni potencijal je testiran na 30 nasumično odabranih klijanaca. Rezultati ukazuju da je regenerativni potencijal individualnih klijanaca bio vrlo varijabilan; sa frekvencom regeneracije od 0.3% do 100% i prosečnim brojem somatskih embriona (SE) po eksplantatu od 0.001 do 9.96. Samo 4 od 30 linija su imale visoku frekvencu regeneracije (85-100%), sa ukupno 227-347 SE regenerisanih sa 30 odsečaka korenova tokom 12 nedelja gajenja. Tokom prve subkulture (4 nedelje) regenerisala je samo jedna linija. Rezultati ukazuju da su jedinke sa visokim regenerativnim potencijalom retke u populaciji sorte \"Matador\". SE izolovani sa korenova istog klijanca su gajeni kao jedna linija na medijumu sa 5 μM kinetinom. Sa klijanaca čiji su korenovi korišćeni za indukciju regeneracije paralelno su izolovani i apikalni pupoljci i gajeni pojedinačno, u epruvetama na medijumu bez regulatora rastenja (BRR). Biljke koje su se razvile iz apikalnih izdanaka klijanaca i iz SE su se samooprašile i dale semena u uslovima in vitro. Na ovaj način, samooplođenjem in vitro i isklijavanjem sakupljenog semena, dobijene su 4 generacije potomačkih klijanaca označenih kao S1-S4. Korenovi ovih klijanaca su korišćeni za indukciju regeneracije SE i njihov embriogeni potencijal je upoređen sa roditeljskim. Embriogeni potencijal S1 i S2 linija je bio takođe vrlo varijabilan. Selekcijom potomstva sa najvećim embriogenim potencijalom dobijene su tri S3 i jedna S4 linija sa izuzetno visokim embriogenim potencijalom, koji je bio 33-53 puta veći u odnosu na majku-biljku. Frekvenca regeneracije ovih linija se kretala oko 100%, a sa 30 fragmenata korenova je izolovano ukupno 1339-2181 SE po klijancu tokom 12 nedelja. Sve linije su regenerisale tokom prve subkulture, 2-4 nedelje ranije u odnosu na roditeljsku liniju.

"Somatic embryogenesis was induced from apical sections of the lateral roots of spinach seedlings (Spinacia oleracea L. cv. Matador), cultivated in vitro on Murashige & Skoog induction medium supplemented with 20μM α-naphthaleneacetic acid (NAA) and 5 μM gibberellic acid (GA3). The capacity for somatic embryo formation was tested in 30 randomly chosen seedlings (lines). Results indicated that the regeneration potential is very variable among the seedlings, with the frequency of regeneration ranging from 0.3% to 100% and the mean somatic embryo (SE) number per explant ranging from 0.001 to 9.96. Only 4 out of 30 lines displayed high regeneration frequency (85-100%), with the total number of 227-347 SEs regenerated from 30 root sections over a 12-week period. Only one line regenerated during the first subculture (4 weeks). Results indicate that the lines with high embryogenic potential are very rare within the population of cultivar \"Matador\". SEs isolated from a single seedling were maintained as a line on medium with 5μM kinetin. Apical shoots, isolated from the same seedlings, which have been used for the induction of regeneration, were cultivated separately in test tubes, on plant growth regulator-free medium. Plants derived from seedlings’ apical shoots and SEs flowered, self-fertilised and set seeds in vitro. Thus, four generations of descendent seedlings, designated as S1-S4, were obtained by self-fertilisation and germination of the collected seeds in vitro. Roots of these seedlings were used for the induction of SE regeneration and their embryogenic capacities were compared to parental lines. The embryogenic capacities of S1 and S2 lines were also very variable. By selection of offspring with high embryogenic response and through further cycles of self-fertilisation, three S3 and one S4 line with extremely high embryogenic capacities, 33-35 fold higher than in the mother-plant, were obtained. The regeneration frequencies of these lines were approximately 100%, and 1339-2181 SEs were isolated from 30 root sections per seedling over a 12-week period. All lines regenerated during the first subculture, and 2-4 weeks earlier compared to parental lines. Root sections of plants regenerated from SE (regenerants) exhibited similar regeneration capacity as the respective seedling from which they originated..."

"Mezenhimske matične ćelije (MMĆ) deo su populacije multipotentnih matičnih ćelija prisutnih u mnogim adultnim tkivima gde učestvuju u održavanju homeostaze. Zahvaljujući sposobnosti samoobnove, potencijalu diferenciranja u specijalizovane ćelije mezodermskog porekla i imunomodultatornim svojstvima, ove nediferencirane ćelije karakteriše širok opseg potencijalne terapijske primene. Regenerativnom kapacitetu MMĆ doprinosi i sposobnost migracije do oštećenih tkiva gde učestvuju u njihovom obnavlјanju što ove ćelije čini pogodnim za ćelijsku terapiju. Mezenhimske MĆ su do sada izolovane iz velikog broja adultnih tkiva i mnoge studije potvrdile su da njihov regenerativni potencijal u velikoj meri zavisi od izvora iz kojeg potiču. Prvobitno su izolovane iz kostne srži koja je do sada najčešće korišćen izvor MMĆ, međutim zbog invazivnih metoda izolacije i malog prinosa MMĆ, stvorena je potreba za alternativnim izvorima. Činjenica da su MMĆ izolovane i iz periferne krvi jedno je od značajnih otkrića iz ove oblasti i smatra se da ove ćelije najverovatnije vode poreklo iz kostne srži, međutim nije dovoljno poznato na koji način migriraju i bivaju privučene u oštećena tkiva. Poslednjih godina se kao povolјan izvor MMĆ sa potencijalnom primenom u regenerativnoj medicini sve češće pominju i perinatalna tkiva (pupčanik i placenta). Prednost pupčanika kao izvora MMĆ ogleda se u lakoj dostupnosti tkiva koje se smatra medicinskim otpadom, neinvazivnoj izolaciji ćelija i činjenici da su izolovane MMĆ po kapacitetu samoobnove i većoj ekspresiji markera pluripotentnost slične embrionalnim MĆ. Iako se već nekoliko decenija MMĆ intenzivno istražuju, uprkos velikom doprinosu nauci i medicini, o njihovom upkupnom terapijskom potencijalu se još uvek nedovoljno zna. Trenutno nije poznat univerzalan mehanizam terapijskog delovanja MMĆ, a mnogobrojni nalazi sve više u poslednje vreme upućuju da ponašanje i uloge MMĆ zavise od konteksta mikrosredine u kojoj obitavaju i/ili deluju, kao mestu integracije spolјnih signala koji određuju sudbinu MMĆ i usmeravaju ih ka određenoj funkciji..."

"present in many adult tissues where they participate in maintaining of homeostasis. Due to their self-renewal capacity, differentiation potential into specialized cells of mesodermal origin and immunomodulatory features, these undifferentiated cells are characterized with wide range of potential therapeutic applications. Their ability to migrate towards damaged tissues where they participate in tissue repair, also contributes to their regenerative potential which makes them suitable for cell therapy. MSCs have so far been isolated from various adult tissues and many studies confirmed that MSCs’ regenerative potential depends largely on the suorce which they originate from. They were originaly isolated from bone marrow which has been the most commonly used source of MSCs so far, however due to invasive methods of isolation and low MSCs yield, there is a need for alternative sources of MSCs. The fact that these cells were isolated from peripheral blood is one of the significant discoveries in this area and it is believed that these MSCs are most likely to originate from bone marrow, but how they migrate and home to damaged tissues has not yet been elucidated completely. Perinatal tissues (umbilical cord and placenta) have been recently increasingly suggested as favourable sources of MSCs with potential applications in regenerative medicine. The advantage of umbilical cord as a source of MSCs is reflected in easy availability of tissue considered as medical waste, non-invasive cell isolation methods, and the fact that MSCs isolated from umbilical cord are similar to embryonic stem cells in the terms of self-renewal capacity and pluripotency markers’ expression. Eventhough MSCs have been extensively investigated for several decades, and despite their great contribution to science and medicine, their overall therapeutic potential is still poorly understood. Currently, there is no universal mechanism of MSCs’ therapeutic action known, and many findings have recently suggested that behaviour and roles of MSCs depend on the context of microenvironment in which they reside and/or act, as sites of integration of external cues that determine the fate of MSCs and govern them towards specific function..."

"Iako se transplantacija matičnim ćelijama hematopoeze kao oblik lečenja koristi više decenija, još uvek nije potpuno jasno zašto postoje razlike u brzini oporavka hematopoeze (vremenu prihvatanja kalema, engl. engrafment) kod bolesnika sa istim oboljenjima, kod kojih su primenjeni istovetni mobilizacioni protokoli i režimi kondicioniranja. Za sagledavanje terapeutskog potencijala matičnih ćelija neophodno je poznavanje njihovih funkcionih karakteristika, između ostalog metaboličkog (energetskog) statusa i redoks-spregnutih mehanizama kontrole diferencijacije u različitim ćelijskim stanjima (mirovanje, opredeljivanje, diferencijacija, aktivacija), tokom hematopoeze. Cilj disertacije je da se ispitaju metabolički parametari u matičnim ćelijama hematopoeze periferne krvi bolesnika sa solidnim tumorima (neuroblastom, NB), Juingov sarkom (engl. Ewing Sarcoma, ES) i limfoma (Hočkinov, HL i non Hočkinov, NHL). Ispitivani su ekspresioni profili enzima ključnih metaboličkih puteva energetskog metabolizma: glikolize, -oksidacije masnih kiselina, ciklusa limunske kiseline, procesa oksidativne fosforilacije (ND4 subjedinica kompleksa I, Ndufa6 subjedinica kompleksa I, citohrom b, citohrom c i subjedinice II (COX II) i IV(COX IV) citohrom c oksidaze) i same sinteze ATP. Ispitivan je i funkcioni status mitohondrija i nivo mitohondrijalne DNK, ekspresija NADPH oksidaze, ekspresija izoformi azot oksid sintaza i produkcija azot oksida, ekspresija enzima antioksidativne odbrane matičnih ćelija hematopoeze (glutation-peroksidaze, GSH-Px), katalaze, mangan superoksid dismutaze (MnSOD), bakar cink superoksid dismutaze (CuZnSOD) i ekspresija interleukina-6 (IL-6) i faktora nekroze tumora (engl. tumor necrosis factor , TNF). Eksperimenti su rađeni na uzorcima monojedarnih ćelija periferne krvi pacijenata koji su primali protokol mobilizacije (MP), pacijenata koji nisu primali protokol mobilizacije i od zdravih davalaca (kontrola). Na osnovu dobijenih rezultata zaključuje se da se izdvajaju dva metabolička fenotipa monojedarnih ćelija iz periferne krvi. Prvi fenotip karakterističan je za monojedarne ćelije periferne krvi kod svih ispitivanih tumora, bez primene protokola mobilizacije. Drugi fenotip istovetan je za monojedarne ćelije periferne krvi svih ispitivanih tumora posle primene protokola mobilizacije..."

"Hematopoietic stem cell transplantation (HSCT) is a standard clinical practice for more than 50 years. However, we still cannot predict with certainty a rate of recovery in the patients with the same disease undergoing identical therapeutic protocols. To determine therapeutic potential of hematopoietic stem cell (HSC), we need to understand better correlation between the metabolic/energy status of the cells and stages of stem cell differentiation during hematopoiesis. Main goal of this work is to investigate metabolic status of peripheral blood mononuclear cells (PBMC) in patients with solid tumors (neuroblastoma, Ewing sarcoma) and lymphoma (Hodgkin and nonHodgkin). We determined expression profiles of key enzymes involved in glycolysis, fatty acid β-oxidation, citric acid cycle, oxidative phosphorylation and adenosine triphosphate (ATP) synthesis: ND4 subunit complexes I, Ndufa6 subunits of complex I, cytochrome b, cytochrome c and subunits II (COX II) and IV (COX IV) cytochrome c oxidase. Next, we investigated number of mitochondria and their function as well as expression levels of nicotinamide adenine dinucleotide phosphate (NADPH) - oxidase, expression isoforms of nitric oxide synthase and production of nitric oxide, expression of HSC antioxidant enzymes (glutathione-peroxidase (GSH-Px), catalase, manganese superoxide dismutase (MnSOD), copper-zinc superoxide dismutase (CuZnSOD)) and expression of interleukin-6 (IL-6) and tumor necrosis factor (TNF). Experiments were performed on PBMC samples of patients that were: a) subjected to mobilization of stem cells from bone marrow, b) not subjected to mobilization, and c) healthy donors (control group). Our results suggested that PBMC metabolic phenotypes differ between mobilized and non-mobilized patients, regardless of diagnosis. These two phenotypes represent functional status of the PBSC at the level of anti-oxidative defense, energy metabolism (glycolysis, -oxidation of fatty acids, citric acid cycle, oxidative phosphorylation-OXPHOS), ATP synthesis, mitochondrial DNA (mtDNK), expression of NADPH oxidase and cytokines IL-6 and TNFα. In samples of non-mobilized HL, NHL and NB patients, we detected a strong metabolic activation of PBMC in comparison with control samples from healthy individuals..."

"taksona koji su izvorno opisani kao zasebne vrste: Diopogon stramineus, S. ciliatum, S. heuffelii, S. kopaonikense, S. patens, S. reginae-amaliae i S. velenovskyi, i njihovi infraspecijski taksoni: S. heuffelii var. albanicum, S. heuffelii var. bulgaricum, S.heuffelii var. glabrum, S. heuffelii var. vestitum. Taksoni J. heuffelii kompleksa su zabeleženi na području centralnog Balkana i Južnih i Centralnih Karpata, na staništima sa širokim dijapazonom nadmorskih visina od 50-2550 m i na različitim podlogama (silikat, krečnjak, serpentinit). Ovakva heterogenost staništa je rezultirala velikom morfološkom varijabilnošću proučavanog kompleksa. Analiza morfoloških karaktera ovog kompleksa, kao i pronalaženje karaktera koji bi eventualno mogli da se koriste u taksonomiji je vrlo bitno u rešavanju vrlo komplikovane situacije kod ovog kompleksa. Osnovni ciljevi ovog istraživanja su bili: utvrđivanje osnovnih karakteristika staništa ispitivanog kompleksa, opisivanje varijabilnosti morfoloških karakteristika vegetativnih i reproduktivnih organa ispitivanih taksona u okviru kompleksa J. heuffelii, utvrđivanje korelacija između promenljivosti morfoloških karakteristika i ekoloških uslova staništa i utvrđivanje rasprostranjenja istraživanog kompleksa. Konačan cilj ovog rada je provera do sada predloženih taksonomskih statusa istraživanih taksona i eventualna promena njihovog ranga. U ovom radu je analizirano 14 populacija kompleksa J. heuffelii koje pokrivaju veći deo areala kompleksa. Tri populacije predstavljaju tipske populacije za taksone S. kopoanikense Pančić (SR-Treska, SR-Nebeske Stolice) i S. patens (RO-Domogled). Morfološka analiza je obuhvatila 299 individua a merenje je izvršeno na 51 karakteru. Podaci o ekologiji i rasprostranjenju kompleksa su prikupljeni terenskim istraživanjima, pregledom herbarijumskih zbirki i literature. Rezultati ove studije su pokazali veću varijabilnost vegetativnih morfoloških karaktera u odnosu na reproduktivne karaktere vrste J. heuffelii. Karakteri koji su dali najveći doprinos u diferencijaciji populacija su: debljina hrskavičavog oboda na listu rozete, dužina cilije na obodu lista rozete i broj listova u rozeti, dužina čašičnog listića, dužina najduže cvetne grane u fazi plodonošenja i dužina semena..."

"Complex Jovibarba heuffelii represents a group of morphologically, chorologically and ecologically very close taxa that were originally described as separate species: Diopogon stramineus, S. ciliatum, S. heuffelii, S. kopaonikense, S. patens, S. reginae-amaliae and S. velenovskyi Cheshm., as well as their infraspecies taxa: S. heuffelii var. albanicum, S. heuffelii var. bulgaricum, S. heuffelii var. glabrum, S. heuffelii var. vestitum. Taxa of J. heuffelii complex were recorded in the region of Central Balkans and South and Central Carpathians, in habitats within a wide range of altitudes (50-2550 m) and on various substrates (silicate, limestone, serpentinite). This heterogeneity of habitat resulted in high morphological variability of the studied complex. Analysis of morphological characters recorded in this complex and determining the characters that might be used in taxonomy are very important for resolving the very complicated situation in this complex. The main goals of this study were to determine: the main characteristics of habitat inhabited by the studied complex, variability of morphological characteristics of vegetative and reproductive organs of studied taxa within the complex of J. heuffelii, correlations between the variability of morphological characteristics and ecological conditions of habitats, and the range of the studied complex. The final goal of this paper is a thorough examination of previously suggested taxonomic statuses of studied taxa and possible changes in their ranking. This paper includes analysis of 14 population of J. heuffelii complex, covering most of the combined range of this complex. Three of these populations are type populations, for taxa S. kopaonikense Pančić (SR-Treska, SR-Nebeske Stolice) and S. patens (RO-Domogled). The morphological analysis included 299 individuals, and measurements were taken for 51 characters. The data on ecology and distribution of this complex were collected in field studies and reviews of herbarium data and literature. The results of this study have shown greater variability in the vegetative morphological characters than in the reproductive characters of species J. heuffelii..."

"Dijabetes tip 1 (DT1) je autoimunsko oboljenje koje nastaje kao rezultat uništavanja insulin-produkujućih beta ćelija pankreasa od strane inflamacijskih medijatora. Uništavanje beta ćelija pankreasa dovodi do smanjene sekrecije insulina i posledične hiperglikemije. Glavna odlika DT1 je insulitis- infiltracija ćelija imunskog sistema u pankreasna ostrvca. Prve ćelije koje infiltriraju pankreasna ostrvca su makrofagi. Smatra se da inflamacijski M1 makrofagi doprinose patogenezi DT1, dok anti-inflamacijski M2 makrofagi imaju protektivnu ulogu. Makrofagi aktiviraju autoreaktivne T limfocite- smatra se da su CD4+ i CD8+ T limfociti najvažnije efektorske ćelije u patogenezi DT1. U zavisnosti od citokina koje sekretuju ćelije imunskog sistema nastaju različite subpopulacije pomoćničkih T limfocita (Th) koje usmeravaju imunski odgovor u DT1 ka destruktivnom (Th1 i Th17) ili protektivnom (Th2 i Treg) odgovoru. Različiti efektorski mehanizmi ćelija imunskog sistema dovode do stvaranja inflamacijskog miljea u paknreasnim ostrvcima koji dovodi do apoptoze beta ćelija pankreasa i razvoja DT1. Terapija DT1 podrazumeva doživotno unošenje insulina. Kako ovo sa sobom nosi potencijal kratkoročnih i dugoročnih komplikacija, ulažu se veliki napori u pronalaženje novih, efikasnih terapija u lečenju DT1. Jedan od potencijalnih pristupa u lečenju DT1 je korišćenje biljaka i njihovih ekstrakata koji se od davnina koriste u tradicionalnoj medicini. Napredak istraživanja u ovoj oblasti doveo je do saznanja da različiti biofenoli koji ulaze u sastav biljaka mogu ostvariti povoljna dejstva na patogenezu različitih oboljenja, što stavlja biljke i njihove ekstrakte u fokus naučnih studija. Origanum vulgare ssp. hirtum (grčki origano) je biljka bogata fenolskim i estarskim jedinjenjima i koja se u tradicionalnoj medicini koristi kao antiseptik, kao i u lečenju stomačnih i respiratornih jedinjenja. Glavna do sada pokazana dejstva origana su anti-bakterijsko i antioksidantno, a pokazano je i anti-hiperglikemijsko dejstvo origana u modelu toksičnog DT1, što čini origano potencijalnim kandidatom za terapiju DT1..."

"Type 1 diabetes (T1D) is autoimmune disorder which develops as a consequence of destruction of insulin-producing pancreatic beta cells which is induced by pro-inflammatory mediators. Beta cell destruction leads to impaired insulin production and loss of glucose homeostasis. The hallmark of T1D is formation of insulitis- immune cells infiltration in pancreatic islets. Macrophages are the first cells that infiltrate pancreatic islets. It is considered that proinflammatory M1 macrophages contribute to T1D pathogenesis, while antiinflammatory M2 macrophages play a protective roll in T1D development. Macrophages can activate autoreactive CD4+ and CD8+ T lymphocites that are considered to be key players in T1D pathogenesis. Cytokines produced by immune cells lead to differentiation of specific T helper cells (Th) subsets, that can be destructive (Th1 and Th17) or protective (Th2 i Treg) in T1D development. Immune cells, by vast effector mechanisms, lead to formation of inflammatory milleu around pancreatic islets which ultimately stimulates beta cell apopotosis. Treatment for T1D includes lifetime intake of insulin which can potentially cause a number of short- and long term complications. This is why scientists invest significant efforts in developing new therapeutic approaches for T1D treatment. Plants and their extracts are promising candidates for treatment of T1D, due to their rich content of phenolic compounds which are proven to be beneficial for human health. Origanum vulgare ssp. hirtum (Greek oregano) is native plant rich in phenolic and ester compounds. It is used in traditional medicine as antiseptic, as well as in the treatment of respiratory and stomach ailments. Main known activities of oregano are antibacterial and antioxidant. Also, recently is reported anti-hyperglycaemic activity of oregano in the model of toxic diabetes. These facts make oregano a promising candidate for the treatment of T1D..."

"Кечига (Acipenser ruthenus L., 1758) представља потамодромну јесетарску врсту, која насељава реке у сливовима Црног, Азовског, Каспијског, Балтичког, Белог, Баренцовог и Кара мора. Значајан пад бројности услед излова током XX века довео је до потребе за бољом заштитом, па је на IUCN Црвеној листи угрожених врста, кечига сврстана међу рањиве врсте (VU). Ради испитивања морфолошке и генетичке диференцијације кечиге у средњем и доњем току Дунава, узорковано је 95 јединки из три популације, од којих две из Србије (Нови Кнежевац на Тиси и Бачка Паланка на Дунаву) и једна популација из Румуније (Гринду на Дунаву). Међупопулациона варијабилност спољашње морфологије (промене величине и облика тела и главеног региона) анализирана је применом метода геометријске морфометрије. Уни- и мултиваријатном анализом варијансе утврђено је постојање статистички значајних разлика у величини и облику анализираних морфолошких целина између јединки са различитих локалитета. Канонијска дискриминантна анализа (CVA) укупне варијабилности облика, код латералног и вентралног приказа тела и латералног приказа главеног региона, показала је да се по првој оси раздваја популација из Румуније од популација из Србије. На нивоу вентралне перспективе тела, као и на нивоу обе перспективе главе утврђен је статистички значајан ефекат алометрије на укупну варијабилност облика. На основу CVA неалометријске компоненте варијабилности облика тела (вентрална перспектива) и главеног региона (латерална и вентрална перспектива) утврђено је да по првој оси постоји раздвајање јединки из Румуније у односу на јединке из Србије. Такође, CVA неалометријске компоненте варијабилности облика главеног региона у обе перспективе указује на могућност да кечиге из Србије (нарочито оне из Тисе) одговарају краткорилој, док кечиге из Румуније одговарају дугорилој форми.

"Sterlet (Acipenser ruthenus L., 1758) is a potamodromus sturgeon species, which inhabits river stretches of Black, Azov, Caspian, Baltic, White, Barents and Kara sea drainages. Sterlet experienced a decline during 20th century, which led to necessity for better protection, and inclusion on IUCN Red List of endangered species as a vulnerable species (VU). То analyse morphological and genetic differentiation of sterlet in Middle and Lower Danube sections, 95 specimens were sampled from three populations, two from Serbia (Novi Kneževac on Tisza River and Bačka Palanka on Danube River) and one from Romania (Grindu on Danube River). Variability of external morphology (size and shape variation of body and head region) was examined using geometric morphometric methods. Statistically significant interpopulation differences in size and shape of analyzed morphological structures were found. Canonical variate analysis (CVA) of overall shape variation (for lateral and ventral views of body and for lateral view of head region) showed that first CV axis separated Romanian sample from Serbian samples. Statistically significant effect of alometry was observed for ventral view of the body, as well as for lateral and ventral views of the head. CVA of non-allometric component of shape variation for body in ventral view and for head in lateral and ventral views showed separation of Romanian population from Serbian populations. Also, non-allometric shape changes of head in lateral and ventral views correspond to shape differences between blunt-snout and pointed-snout sterlet morphs. Use of mitochondrial DNA and microsatellite markers, showed significant level of diversity (13 haplotypes, allelic richness range from 4.3 to 4.9, observed heterozygosity from 0.577 to 0.648). Genetic analysis (mtDNA and microsatellite) showed lack of clear population differentiation. Additionally, five new haplotypes were detected, while eight previously described haplotypes had extended their previous range. Analysis of molecular variance indicated that the genetic variance could be attributed almost entirely to individuals from same populations and that interpopulation variability was absent. Samples from the Danube River were most divergent (FST=0.038), while lowest FST (0.018) was observed between samples from Serbia (Tisza and Danube River)..."

"Karcinom dojke je i klinički i genetički heterogeno oboljenje sa varijabilnim odgovorom na terapiju. Estrogenski – ER, progesteronski – PR i receptor za humani epidermalni factor rasta 2 – HER2, najbitniji su biološki markeri na osnovu čije ekspresije se karcinomi dojke dele na: trostruko negativne (TNBC) koji ih ne eksprimiraju i na hormonski zavisne (ER+) tumore koji eksprimiraju ER, a pokazuju varijabilnu ekspresiju PR i HER2. Ovi markeri ključni su i za izbor terapije. TNBC i ER+ karcinomi dojke se rezlikuju po svom kliničkom ponašanju, karateristikama i agresivnosti. TNBC je daleko agresivniji. Navedene razlike posledica su genetičkih lezija čije bi tumačenje moglo da doprinese razvoju novih strategija u terapiji ovih tumora. U vezi sa tim, osnovni cilj ove studije bio je utvrđivanje amplifikacionog obrasca odabrane grupe onkogena, FGFR1, c-MYC, EGFR i CCND1, u oba tipa karcinoma dojke kao i povezivanje njihovog amplifikacionog statusa sa kliničkim tokom i ishodom bolesti. Rezistencija na sistemsku terapiju je osnovni problem u tretmanu oba tipa karcinoma dojke. Ovaj problem posebno je izražen kod obolelih od TNBC koji se zbog odsustva ekspresije ER, PR i HER2, tretiraju isključivo citostaticima na koje vrlo često razvijaju rezistenciju. Zato je jedan od osnovnih ciljeva ove studije bio i identifikacija bioloških mehanizama koji leže u osnovi rezistencije na hemioterapiju, odnosno ispitivanje ekspresionog profila BCRP i MRP1 membranskih transportera i njihove povezanosti sa tokom i ishodom bolesti. Amplifikacioni status analiziranih onkogena ispitan je RT-qPCR metodom, a ekspresioni profil membranskih transportera imunohistohemijskom analizom – IHC. Uporednom analizom amplifikacionog profila četiri onkogena u dva tipa karcinoma dojke, utvrđeno je da se drugačije ponašanje, karaketristike i agresivnost TNBC tumora mogu pripisati značajno češćoj amplifikaciji c-MYC onkogena u ovoj grupi tumora..."

"Breast cancer is both clinically and genetically a heterogeneous disease with variable response to therapy. Based on the expression of tree most important biological markers, estrogen receptor – ER, progesterone receptor – PR and human epidermal growth factor receptor 2 – HER2, breast cancer can be divided into: triple negative (TNBC) that do not express these receptors and hormone dependent (ER+) tumors that express ER and have a variable expression of PR and HER2. These markers are key for determining therapy. TNBC and ER+ breast cancers differ in their clinical behavior, characteristics and aggressiveness. TNBC is by far more aggressive type. Clarification of genetic lesions that induce the mentioned differences could contribute to the development of new therapeutic strategies for these tumors. Therefore, the main aim of this study was to determine the amplification pattern of the selected oncogene group, FGFR1, c-MYC, EGFR and CCND1, in both types of breast cancer, as well as to investigate a possible connection of amplification status of these oncogenes with the clinical course and outcome of the disease. Resistance to systemic therapy is a primary problem in treatment of both types of breast cancer. This problem is especially pronounced in patients with TNBC that, due to the absence of ER, PR and HER2 expression, are only treated with cytostatics to which they frequently develop resistance. For this reason, one of the main aims of this study was to identify biological mechanism that are the basis of chemoresistance, namely, to investigate the expression profiles of BCRP and MRP1 membrane transporters and their connections with the clinical course and outcome of the disease. The amplification profile of the analyzed oncogenes was investigated using RT-qPCR, while the expression profile of the membrane transporters was analysed by immunocytochemistry – IHC...."

"Stopa rasta gojaznosti predstavlja glavni javni zdravstveni problem. U Evropi je njena učestalost u opsegu 10-25% kod muškaraca i 10-30% kod žena. Prevalenca gojaznosti je povećana u Srbiji i ona je postala značajan zdravstveni problem kod odraslih u Srbiji: do 54% ispitanika odraslog stanovništva je gojazno. Gojaznost je bolest koja se definiše kao patološka akumulacija telesne masne mase, koja može nastati kao rezultat povećanog unosa energije i smanjene potrošnje energije. Danas se smatra da je genetska predispozicija za nastanak gojaznosti jedan od glavnih faktora rizika za pojedince, ali identifikaciju gena koji su uključeni u nastanak gojaznosti je još uvek teško razjasniti. S obzirom na činjenicu da je koncentracija leptina znatno povećana kod gojaznih osoba, a istovremeno je proporcionalna telesnoj masi, gen leptina (LEP) je procenjivan u odnosu na genetičke varijante koje bi eventualno mogle biti u vezi sa patofiziologijom gojaznosti i njenim komplikacijama. Leptin je hormon protein kodiran genom gojaznosti (ob), a sintetiše ga pretežno belo masno tkivo. Centralni nervni sistem, tačnije jedra hipotalamusa su meta u kojima leptin ispoljava većinu svojih efekata na metabolizam energije. Leptin ostvaruje nekoliko sistemskih efekata kao što: su smanjenje unosa hrane, povećanje energetske potrošnje, kao i smanjenje metaboličke efikasnosti. Pored toga, leptin utiče na širok spektar bioloških funkcija poput metabolizma lipida i glukoze, sintezu glukokortikoida kao i insulina, a postoji sve više dokaza da je leptin uključen i u patogenezu inflamatornih i autoimunih bolesti. Adekvatne masne naslage i koncentracija leptina smanjuju potrebu za unosom hrane, a omogućavaju potrošnju energije putem raznih neuroendokrinih osa i autonomne aktivnosti. Retki sindromi gojaznosti su povezani sa mutacijama LEP gena kod ljudi. Česta genetička varijanta jednog nukleotida u 5 'promotorskom regionu koji se sastoji u supstituciji G u A na nukleotidu (nt) -2548 (LEP G-2548A, -dbSNPID rs7799039) uzvodno od starta transkripcije ATG u promotoru LEP je povezan sa varijacijama koncentracije leptina u plazmi i indeksom telesne mase (BMI) kod gojaznih osoba..."

"The growth in obesity rates presents a major public health concern. In Europe, its prevalence is within the range of 10–25% in men and 10–30% in women. The prevalence of obesity increased in Serbia and it became a significant public health problem among adults: up to 54% examinees of adult populations were obese. Obesity is a disease defined as abnormal accumulation of body fat mass, which may arise as a result of increased energy intake and decreased energy expenditure. Genetic predisposition to obesity has been reported as a major risk factor for individuals, but identification of the involved genes is still difficult to elucidate. Considering the fact that leptin concentration is significantly increased in obese persons and at the same time is proportional with body weight, the leptin gene (LEP) has been evaluated for polymorphisms that could potentially be related to the pathophysiology of obesity and its complications. Leptin is a protein hormone encoded by the obese (ob) gene, and is synthesized predominantly by white adipose cells. Central nervous system, namely hypothalamic nuclei, is the target where leptin exerts most of its effects on energy metabolism. Leptin has several systemic effects such as decreases food intake, increases energy expenditure, and decreases metabolic efficiency. In addition, leptin has been shown to influence a wide spectrum of biological functions, such as lipid and glucose metabolism, synthesis of glucocorticoids as well as insulin, and there is an increasing evidence that leptin is involved in the pathogenesis of inflammatory, and autoimmune diseases. Adequate fat stores and leptin concentrations decrease the need for food intake however, allow expenditure of energy via a variety of neuroendocrine axes, autonomic outputs and activities. Rare obesity syndromes are associated with mutations of LEP in humans. A common single nucleotide polymorphism within the 5′ promoter region consisting in G to A substitution at nucleotide (nt) -2548 (LEP G-2548A, -dbSNPID rs7799039) upstream of the ATG start site, in LEP promoter has been associated with variations in the concentrations of plasma leptin and body mass index (BMI) in obese individuals. It has been shown that LEP G-2548A polymorphism influences expression and secretion of leptin in adipose tissue..."

"Inflamacija je zajedničko obeležje različitih patologija centralnog nervnog sistema (CNS), od traumatskih povreda i ishemije, preko neurodegenerativnih oboljenja, do psihijatrijskih poremećaja. Mikroglijske ćelije su rezidentne imunske ćelije CNS-a koje predstavljaju glavne pokretače i učesnike u inflamaciji. Mikroglija se aktivira u odgovoru na promene u homeostazi CNS-a pri čemu menja svoje morfološke i funkcionalne karakteristike. U aktiviranoj mikrogliji dolazi do reorganizacije citoskeleta što omogućava uvećanje ćelijskog tela, fagocitozu patogena ili ćelijskog otpada, kao i migraciju do mesta infekcije ili povrede. Takođe, aktivirana mikroglija produkuje brojne proinflamatorne medijatore, kao što su proinflamatorni citokini, hemokini, proteaze, reaktivne kiseonične i azotne vrste. Iako ovi molekuli imaju važnu ulogu u odbrani CNS-a od patogena i drugih štetnih stimulusa, oni tokom hronične aktivacije mikroglije dovode do snažnog inflamatornog odgovora, oštećuju i zdrave ćelije i dovode do neurodegeneracije. Stoga je smanjenje prekomerne mikroglijske aktivacije jedna od glavnih strategija u terapiji oboljenja CNS-a koja se odlikuju inflamacijom. Benfotiamin (S-benzoiltiamin O-monofosfat) je analog vitamina B1 sa većom biološkom raspoloživošću i dobrim farmakološkim profilom. Benfotiamin pokazuje povoljne efekte u lečenju neuropatija, nefropatija i retinopatija izazvanih dijabetesom. Pored toga, pokazana su antiinflamatorna i antioksidativna svojstva benfotiamina, ali njegov efekat na aktiviranu mikrogliju do sada nije poznat. Stoga, cilj ove disertacije bio je da se ispita potencijal benfotiamina da smanji aktivaciju mikroglije u in vitro modelu neuroinflamacije. Eksperimenti su rađeni na BV-2 mikroglijskoj ćelijskoj liniji koja je bila stimulisana lipopolisaharidom (LPS), što predstavlja dobro okarakterisan in vitro model aktivacije mikroglije. Rezultati dobijeni u ovoj disertaciji pokazuju da benfotiamin sprečava morfološke promene izazvane stimulacijom BV-2 ćelija LPS-om..."

"Optiĉka spektroskopija i imidţing tehnike mogu biti korisne za ranu dijagnostiku kancera. U ovoj tezi, razlike u luminescentnim odgovorima pigmentnih lezija (melanoma i nevusa) i po svemu sudeći nepigmentne koţe ljudi su analizirane sinhronom luminescentnom spektroskopijom. Merenja su izvršena u opsegu eksitacione talasne duţine od 330 do 545 nm i sinhronom intervalu od 30 do 120 nm, da bi se dobili osnovni i trodimenzionalni sinhroni luminescentni spektri (3DTSLS) za svaki uzorak. Normalna koţa, nevus i melanom se razlikuju u naĉinu na koji fluoresciraju, i te razlike su više naglašene u sinhronim fluorescentnim spektrima nego u klasiĉnim emisionim i eksitacionim spektrima. Razlike u fluorescentnim karakteristikama pigmentnih lezija i zdrave koţe potiĉu od razliĉitih koncentracija endogenih fluorofora i hromofora. Analizom glavnih komponenata i linearnom diskriminantnom analizom sinhronih spektara izmerenih za razliĉite sinhrone intervale pokazano je da je najveća razlika izmeĊu grupa uzoraka dobijena za sinhroni interval 70 nm. Ovi spektri su zatim korišćeni za pravljenje klasifikacionih modela diskriminantnom analizom parcijalno najmanjih kvadrata. Testiranjem uspešnosti ovih modela krivom operativnih karakteristika pokazano je da su oni optimalni, sa maksimalnom vrednošću od jedan za površinu ispod krive operativnih karakteristika za detekciju melanoma. Za testiranje primenjivosti pomenutih tehnika korišćene su veštaĉke neuronske mreţe. U ovu svrhu, samoorganizujuće mape (SOM) i višeslojni perceptron (MLP) su obuĉene na osnovu luminescentnih podataka, a zatim je izvršeno grupisanje uzoraka tkiva. Pokazano je da su obe mreţe SOM i MLP dale dobre rezultate sa stopom uspešnosti klasifikacije uzoraka tkiva od 96% i 98%. Drugi deo eksperimentalnog rada u ovoj tezi se sastojao od merenja difuzno refleksionih spektara koţe volontera na dve regije tela, ĉelu i šaci, u cilju analize svojstava boje koţe na objektivan naĉin. Dobijeni spektri su analizirani korišćenjem analize glavnih komponenata (PCA) i L*a*b* sistema boja koji je preporuĉen od MeĊunarodne komisije za osvetljenje (CIE). Na osnovu rezultata analiza pokazano je da difuzno refleksiona spektroskopija uz korišćenje analize glavnih komponenata i L*a*b* sistema boja predstavlja korisnu i objektivnu metodologiju za analiziranje karakteristika koţe."

"Novel optical spectroscopy and imaging methods could be valuable in the early detection of cancer. Differences in the luminescence responses of pigmented skin lesions (melanomas and nevi) and apparently non-pigmented human skin were analyzed using synchronous luminescence spectroscopy in this thesis. Measurements were performed in the excitation range of 330-545 nm, with synchronous interval varyng from 30-120 nm to obtain ordinary and three-dimensional total synchronous luminescence spectra (3DTSLS) of each specimen. Normal skin, nevi and melanomas differ in the way they fluorescence, and these differences are more distinct in the syncronous fluorescence spectra than in the conventional emission and excitation spectra. The differences in the fluorescence characteristics of pigmented and normal skin samples were ascribed to differences in concentracions of endogenous fluorophores and chromophores. Principal component and linear discriminant analysis of the synchronous spectra measured at different synchronous intervals showed that the greatest variance among the sample groups was at the 70 nm interval spectra. These spectra were then used to create partial least squares discriminant analysis-based classification models. Evaluation of the quality of these models from the recevier operating characteristic curves showed they performed well, with a maximum value of one for the area under the curve for melanoma detection. To test applicability of the presented techniques artificial neural networks were used. For this purpose self organizing maps (SOM) and multi layer feed-forward neural network (MLP) were trained with luminescence data and then used for tissue specimen clustering. It was shown that both SOM and MLP gave promising results with 96 to 98% success tissue classification rate. Second part of experimental work in this thesis were measurements of diffuse reflectance spectra from skin sites located on a forehead and top of a hand of healthy volunteers in order to analyze skin color properties in an objective way. Obtained spectra were analyzed using principal component analysis (PCA) and standard Commission International d'Eclairage (CIE) L*a*b* color scheme. Based on results of analysis it was shown that diffuse reflectance spectroscopy combined with the PCA and the L*a*b* color system is a convenient and objective methodology for analyzing skin properties."

"Široka rasprostranjenost slatkovodnih školjki, ishrana filtriranjem, sesilni način života i sposobnost da akumuliraju zagađivače čine ih pogodnim organizmima za procenu nivoa zagađenja spoljašnje sredine i uticaja različitih zagađivača. Komet, test ili elektroforeza pojedinačnih ćelija (eng. single cell gel electrophoresis - SCGE) je osetljiva i brza tehnika za detekciju DNK oštećenja u pojedinačnim ćelijama i predstavlja jednu od osnovnih metoda u praćenju genotoksičnog efekta zagađivača na akvatične organizame. Da bismo odredili osetljivost školjki kao bioindikatora u ekogenotoksikološkim studijama, primenom alkalnog komet testa pratili smo nivo oštećenja molekula DNK u hemocitama slatkovodnih školjki Unio pictorum i U. tumidus (autohtone vrste) i Sinanodonta woodiana (alohtona vrsta) izlaganih sredinskom stresu in situ i ex situ. U okviru in situ proučavanja, aktivnim i pasivnim biomonitoringom, pratio se uticaj sredine na nivo oštećenja DNK molekula. Procena kvaliteta vode na različitim lokalitetima vršena je na osnovu mikrobioloških i fizičko-hemijskih parametara. Pasivni biomonitoring je rađen u okviru istraživanja na reci Velika Morava, na jedinkama vrste S. woodiana i u okviru istraživanja na reci Dunav, na jedinkama roda Unio. Aktivni biomonitoring je rađen sa jedinkama istog roda na lokalitetima Save i Dunava na teritoriji grada Beograda. U okviru ex situ proučavanja, pratio se uticaj citostatika: 5-fluorouracila, cisplatine, etopozida, vinkristin sulfata i imatinib mezilata na nivo oštećenja DNK molekula u hemocitama vrsta roda Unio in vivo, izlaganjem jedinki 72 h, i in vitro, izlaganjem sveže izolovanih hemocita (30 min) ili hemocita u primarnoj kulturi (22 h). Kao model mutagen, korišćen je kadmijum hlorid koji je u svim tretmanima doveo do indukcije oštećenja DNK molekula.

"Due to generally wide distribution of considerable number of species, filter feeding, a sessile life form and an ability to accumulate pollutants, freshwater mussels were found to be favourable organisms for estimating the environmental pollution level and the impact of various pollutants. The comet assay or the single cell gel electrophoresis (SCGE) represents a sensitive and rapid technique for detection of DNA damage and thus this method is commonly employed for detection of genotoxic pollution in aquatic ecosystems. To evaluate the sensitivity of freshwater mussels as bioindicators in ecogenotoxicological studies, we studied the level of DNA damage with alkaline comet assay in haemocytes of freshwater mussels Unio pictorum and U. tumidus (autochtonous species) and Sinanodonta woodiana (alochtonous species) exposed to environmental stress in situ and ex situ. For in situ studies, active and passive biomonitoring were employed for the evaluation of the impact of environmental stress on the level of DNA damage. Water quality assessment on studied sites was based on physical, chemical and microbiological parameters. Passive biomonitoring was performed on specimens of S. woodiana collected from the Velika Morava River, and on two species bellonging to genus Unio collected from the Danube River. Active biomonitoring was performed on specimens of the same species exposed in the Sava and Danube rivers in the urban area of the Belgrade city. Ex situ studies of the impact of cytostatics: 5-fluorouracil, cisplatin, etoposide, vincristine sulphate and imatinib mesylate were performed in vivo, by treatment of the whole animals for 72, and in vitro, by treatment of freshly isolated haemocyes for 30 min or by treatment of haemocytes in primary cultures for 22 h. Treatment with cadmium chloride (model mutagen) resulted in significant induction of DNA damage in all treatment conditions..."

"Cistus creticus L. je višegodišnja, žbunasta biljka koja nastanjuje suva i topla područja Mediterana. Smolu ove vrste lokalno stanovništvo Krita sakuplja od davnina zbog izraženih aromatičnih i lekovitih svojstava. Dominantna biološki aktivna komponenta smole i izdanaka ove biljke su labdanski diterpeni, dok je koren biljke još uvek nepoznatog sastava. U cilju iznalaženja optimalnih uslova za produkciju labdanskih diterpena predmet istraživanja ove disertacije bio je ispitivanje regulacije produkcije labdanskih diterpena u biljkama C. creticus gajenim in vitro pod uticajem različitih abiotičkih faktora i hranljivih podloga sa varirajućim sadržajem različitih šećera. Uspešno je uspostavljena in vitro kultura biljaka C. creticus na MS medijumu bez fitohormona, pri čemu parametri rastenja i razvića eksplantata nisu pokazali značajne razlike između ispitivanih klonova. Optimalne koncentracije ugljenih hidrata za rastenje i razviće biljaka C. creticus u uslovima in vitro su od 0,03 M do 0,1 M saharoze i glukoze. Histohemijskim analizama listova izdanaka gajenih in vitro je utvrđeno da kapitatne glandularne trihome tipa II C. creticus predstavljaju mesto akumulacije labdanskih diterpena i fenolnih jedinjenja. Genetička transformacija C. creticus je izvršena pomoću Agrobacterium rhizogenes A4M70GUS, pri čemu je uspostavljena kultura transformisanih korenova. Fitohemijska karakterizacija biljaka C. creticus gajenih in vitro, omogućila je identifikaciju i kvantifikaciju glavnih grupa sekundarnih metabolita (terpena i fenolnih jedinjenja) koji se u ovim uslovima produkuju. Labdanski diterpeni su dominantna jedinjenja u izdancima biljaka C. creticus gajenim in vitro, a među njima su najzastupljeniji labd-7,13-dien-15-ol i labd-7,13-dien-15-ol acetat. Od isparljivih sekundarnih metabolita najzastupljeniji su monoterpeni i seskviterpeni. U dihlormetanskim ekstraktima eksudata kapitatnih trihoma tipa II najzastupljenije jedinjenje je labd-7,13-dien-15-ol acetat. U korenovima C. creticus potvrđeno je prisustvo fenolnih jedinjenja i masnih kiselina, dok labdanski diterpeni nisu detektovani. Analiza sadržaja fenolnih jedinjenja ukazala je da su u etanolnim ekstraktima izadanaka i korenova prisutna fenolna jedinjenja kao što su hininska kiselina, galokatehin i katehin..."

"Cistus creticus L. is a perennial, bushy plant that inhabits mainly dry and warm areas of the Mediterranean. The resin of this species has been actively collected by the local inhabitants of Crete since ancient times due to its aromatic and medicinal properties. The predominant bioactive component of the resin and the shoots of this plant are labdane diterpenes, while the chemical composition of the roots is still unknown. In order to find the optimal conditions for the labdane diterpenes production, the subject of this thesis was to investigate the regulation of labdane-type diterpenes production in in vitro grown plants of C. creticus, as influenced by various abiotic factors and growth media with varying content of different carbohydrates. In vitro culture of C. creticus was successfully established on hormone-free MS medium, and the parameters of growth and development of explants showed no significant differences among analyzed clones. Optimal concentrations of carbohydrates for in vitro growth and development of C. creticus ranged from 0.03 M to 0.1 M sucrose or glucose. Genetic transformation of C. creticus was performed with Agrobacterium rhizogenes A4M70GUS and the culture of transformed roots was established. Regeneration of transformed plants was unsuccessful. Histochemical analysis of the leaves from in vitro cultured C. creticus shoots showed that labdane diterpenes and phenolic compounds accumulate in the type II capitate glandular trichomes. Phytochemical characterization of in vitro grown C. creticus has enabled the identification and quantification of two major groups of secondary metabolites (terpenes and phenols), which are produced under these conditions. Predominant compounds accumulating in shoots of C. creticus grown in vitro were labdane diterpenes, the most abundant among them being labd-7,13-diene-15-ol and labd-7,13-dien-15-ol acetate. Amongst the volatile secondary metabolites, the most abundant were monoterpenes and sesquiterpenes. Labd-7,13-dien-15-ol acetate was the most abundant compound in dichloromethane extracts of type II capitate trichomes exudates. In the roots of C. creticus, the presence of the phenolic compounds and fatty acids was determined, whereas labdane diterpenes were not detected..."

"Protrombin (Faktor II) je prekursor trombina, jednog od ključnih molekula u održavanju hemostazne ravnoteže. Povišeni nivo protrombina dovodi do poremećaja hemostazne ravnoteže i stanja hiperkoagulacije, koje se manifestuje pojavom tromboza. Pokazano je da 3kraj protrombinskog gena poseduje nekanonsku organizaciju, usled čega je podložan mutacijama koje dovode do povećane ekspresije protrombina i povišenog rizika za pojavu trombofilije. U okviru prethodne studije, sprovedene u Laboratoriji za molekularnu biologiju, Instituta za molekularnu genetiku i genetičko inženjerstvo, Univerziteta u Beogradu, u poslednjem egzonu gena za protrombin identifikovana je promena citozina (C) u timin (T) na mestu 20068. Ova genska varijanta dovodi do zamene CGC kodona za arginin u CGT kodon koji takođe kodira za arginin na poziciji 608 u proteinu. U bazi dsSNP/NCBI je klasifikovana kao sinonimna promena, pod brojem rs3136532. Pokazano je da je ova genska varijanta zastupljenija kod pacijenata sa trombozama i da njeno prisustvo dovodi do povećane ekspresije iRNK. Prvi deo istraživanja, u okviru ove doktorske disertacije, podrazumevao je određivanje učestalosti genske varijante C20068T u grupi pacijenata sa trombofilijom, kao i u odgovarajućoj grupi zdravih ispitanika, čime bi se utvrdilo da li ova varijanta predstavlja potencijalni novi trombofilni marker. Drugi deo istraživanja obuhvatio je funkcionalnu analizu C20068T varijante, u cilju rasvetljavanja mehanizma kojim ova sinonimna varijanta utiče na promenu ekspresije gena za protrombin. U okviru ove studije testirano je ukupno 797 ispitanika, od toga 606 pacijenata i 191 ispitanik kontrolne grupe. Pacijenti su podeljeni u grupe, shodno poremećaju od koga su bolovali, u grupu pacijenata sa trombotičkim poremećajima (443 pacijenta, od čega: 106 sa cerebrovaskularnim insultom, 101 sa plućnim embolizmom, 175 sa trombozom dubokih vena i 61 sa kombinovanim trombotičkim poremećajima) i grupu pacijentkinja sa spontanim pobačajima (163 pacijentkinje). U grupi pacijenata sa cerebrovaskularnim insultom detektovana su tri heterozigotna nosioca C20068T varijante (OR 5,53; P=0,13)..."

"Prothrombin (Factor II) is a precursor of thrombin, one of the key regulatory enzymes in the maintainance of haemostasis. Elevated level of prothrombin leads to haemostatic disbalance and hypercoagulation, which can manifest as thrombotic disorders. The 3end of the prothrombin gene has noncanonical architecture that is sensitive to gain-of-function mutations, leading to increased prothrombin expression and elevated risk for thrombophilia. In our previous study we detected a novel C to T point mutation at the position 20068 in the last exon of the prothrombin gene. This gene variant leads to exchange of CGC to CGT codon which both code for arginine at the position 608 in the protein. C20068T gene variant is clasified as synonymous gene variant, under reference SNP ID number 3136532. This variant was more frequent in the patients with thrombosis compared to controls and leads to increased prothrombin mRNA expression. The first aim of this study was to determine the prevalence of C20068T gene variant in patients with thrombophilia, as well as in healthy controls. The second aim of this study was to elucidate the mechanism by which C20068T variant affects the prothrombin gene expression and pathogenesis of thrombophilia. This study included 797 subjects, divided in study and control groups. Patients were divided in five groups, according to thrombotic event they suffered from: 443 with several thrombotic manifestations, including 106 patients with cerebrovascular insult, 101 patient with pulmonary embolism, 175 patients with deep vein thrombosis and 61 patient with combined thrombotic events. This study also included 163 women who suffered from foetal losses. In the groups of patients with cerebrovascular insult, we have detected three heterozygous carriers of C20068T variant (OR 5.53; P=0.13), as well as in the group of patients with isolated pulmonary embolism (OR 5,81; P=0,12. In patients with deep vein thrombosis, 6 carriers of 20068CT genotype were detected (OR 6.74; P=0.057. Three heterozygous carriers were detected in the patients with combined thrombotic manifestations (OR 9.83; P=0.045). Our results indicate that C20068T represents significant risk factor for thrombotic occurence (OR 6.66; P=0.049)..."

"Iako se pacovski model pulmonarne aspergiloze koristi podjednako kao i mišiji modeli u ispitivanju antigljivičnih terapija, slabije su ispitane karakteristike imunskog odgovora na infekciju izazvanu gljivom roda Aspergillus kod pacova. U ovom radu ispitan je imunski odgovor u plućima na subletalnu infekciju izazvanu gljivom A. fumigatus kod dva soja pacova, Albino Oxford (AO) i Dark Agouti (DA), za koje je poznato da razvijaju kvalitativno različit odgovor u nekim inflamatornim oboljenjima. Sporije uklanjanje gljive nakon intratrahealnog (i.t.) ubrizgavanja 107 konidija zapaženo je kod jedinki AO soja (do 21. dana nakon infekcije u poređunju sa 14 dana kod DA pacova). Kod oba soja uklanjanje gljive iz pluća se odigrava u sličnoj sredini: povišeni nivoi proinflamatornih citokina interferona -γ (IFN-γ) (nivo IFN-γ je blago viši kod inficiranih jedinki DA soja trećeg dana nakon infekcije) i interleukina-17 (IL-17) dok je nivo Th2/antiinflamatornih citokina (IL-4 i IL-10) bio nepromenjen. Iako je sadržaj proinflamatornih citokina u homogenatu pluća sličan kod oba soja, kod jedinki AO soja uklanjanje gljive iz pluća je povezano sa manjim stepenom infiltracije leukocita u tkivo i nižim osnovnim efektorskim aktivnostima ćelija (ekspresija CD11b molekula, adhezija, produkcija reaktivnih vrsta kiseonika i aktivnost unutarćelijske mijeloperoksidaze). Leukociti izolovani iz pluća jedinki oba soja produkovali su slične količine citokina koji stimulišu efektorske aktivnosti ćelija, IFN-γ i IL-17, u toku infekcije (izuzev u kasnijim terminima nakon infekcije). Nasuprot tome, količina produkovanog IL-10 je bila značajno viša u kulturi leukocita pluća izolovanih iz jedinki AO soja. U regionalnim limfnim čvorovima (mestima gde se nastaju ćelije koje produkuju citokine) zapaža se diferencijacija ćelija u smeru produkcije IFN-γ (veće količine u kulturi ćelija jedinki AO soja), IL-17 (niže količine kod jedinki AO soja) i IL- 10. Nepromenjena (smanjena antigen specifična) produkcija IL-4 je takođe zapažena. CD4+ ćelije u regionalnom čvoru su glavni producenti IFN-γ, IL-17 i IL-10. Ove ćelije nakon diferentovanja migriraju u pluća sudeći po povećanju broja CD4+ ćelija u digestu pluća i bronholaveolarnom ispirku. Poznavanje mehanizama odbrane u infekciji izazvanoj gljivom A. fumigatus kod pacova može da doprinese upotrebi pacovskog modela pulmonarne aspergiloze u razvijanju i testiranju novih terapeutskih modaliteta u tretmanu infekcija izazvanih gljivama."

"Although rat models of pulmonary aspergillosis are used to same extent as mouse models in exploring antifungal therapeutics, the understanding of immunology of Aspergillus infection in rats is deficient. In this study pulmonary immune responses to sublethal A. fumigatus infection were investigated in two rat strains, Albino Oxford (AO) and Dark Agouti (DA), differently susceptible to some inflammatory diseases. Slower elimination of fungus following intratracheal (i.t.) application of 107 conidia was noted in AO rats (by the day 21 post infection, compared to day 14 in DA rats). In both rat strains elimination of fungi occurs in similar environment: enriched in proinflammatory cytokines interferon-γ (IFN-γ) (level of IFN- γ was slightly higher in infected DA rats at day 3 p.i.) and interleukin-17 (IL-17) and unchanged Th2/antiinflammatory cytokines (IL-4 and IL-10). Although proinflammatory cytokines were present at similar amount in lung tissue homogenates, in AO rats elimination of fungi from lungs was associated with lower degree of lung leukocyte infiltration and their basic effector activities (i.e. CD11b expression, adhesion, production of reactive oxygen species, intracellular myeloperoxidase content). Generally, similar levels of effector cell-stimulating proinflammatory cytokines IFN-γ and IL -17 production by lung leukocytes during the entire post-infection period (except late in infection) were noted in both strains. In contrast, production of IL-10 was found to be significantly higher in AO rats. In draining lymph nodes (as sites of generation of cytokine-producing cells) cells differentiate toward IFN-γ-producing cells (higher amount of this cytokine detected in infected AO compared to DA rats), IL-17-producing cells (levels of cytokine produced lower in AO compared to DA rats) and IL-10 producing cells (similar levels in both strains). Unchanged (and even decreased antigen specific) IL-4 production was noted as well. CD4+ cells differentiated in draining lymph nodes are the main source of IFN-γ, IL-17 and IL-10. These cells following differentiation migrate to the lung tissue, judging by increased number of CD4+ cells in lung tissue digest and BAL cells.The knowledge of mechanisms of defense against A. fumigatus in rats might be helpful in the future use of rat models of pulmonary aspergillosis in developing and testing immunotherapeutic interventions of fungal diseases."

"Matriksne metaloproteinaze (MMP) i tkivni inhibitori matriksnih metaloproteinaza (TIMP) su molekuli odgovorni za procese remodeliranja ćelijske mikrosredine i neophodni su za održanje homeostaze tkiva. Neadekvatna regulacija ovih procesa je uzrok mnogih patoloških stanja uključujući nastanak i progresiju malignih oboljenja. Tiroidni karcinom predstavlja najčešći endokrini malignitet sa incidencom u porastu u različitim delovima sveta. Neoplastičnom transformacijom tiroidnog epitela potencijalno nastaje veliki broj malignih i benignih neoplazija sa velikim varijacijama u kliničkoj slici, agresivnosti i ishodu. Ograničena mogućnost predikcije razvoja nepovoljnih i metastatskih karakteristika tiroidnih karcinoma je trenutno jedan od glavnih problema u kliničkoj praksi pri izboru tretmana obolelih. Cilj ove teze bio je ispitivanje ekspresije i aktivnosti dve metaloproteinaze, MMP-2 i MMP-9, kao i ekspresije njihovog inhibitora TIMP-2, kao markera koji bi mogli da budu od pomoći u diferencijalnoj dijagnostici tiroidnih neoplazija i prognostičkoj stratifikaciji obolelih. Analiza je obuhvatila arhivski i svež materijal tiroidnog tkiva dobijen nakon operacije pacijenata sa benignim ili malignim tumorom štitaste žlezde, a kao kontrolni materijal korišćeno je “zdravo” tiroidno tkivo pacijenata odstranjeno uz tumor. Za analizu je korišćena imunohistohemijska metoda i metode želatin zimografije (SDS-PAGE i in situ). Imunohistohemijskom analizom pokazano je da MMP-2, MMP-9 i TIMP-2 imaju veću ekspresivnost u papilarnom tiroidnom karcinomu u odnosu na folikularni tiroidni adenom, folikularni tiroidni karcinom i uslovno zdravo tkivo štitaste žlezde, što pruža dodatne informacije prilikom rutinske mofološke analize tkiva. Poređenjem imunohistohemijske ekspresije MMP-2 sa kliničkopatološkim parametrima pacijenata sa papilarnim tiroidnim karcinomom utvrđena je značajna korelacija između ekspresije MMP-2 i prisustva metastaza u limfnim čvorovima, dok su ekspresioni profili TIMP-2 pokazali značajnu korelaciju sa kliničkopatološkim parametrima vezanim za progresiju karcinoma (veličina tumora i pojava ekstratiroidne invazije). Imunohistohemijski detektovana aktivna forma MMP-9 je pokazala snažnu asocijaciju sa većinom ispitanih kliničkopatoloških parametara papilarnog karcinoma: veličinom tumora, prisustvom ekstratiroidne invazije i limfnih metastaza, stadijumom karcinoma i dubinom njegove neoplastične infiltracije, što ovaj molekul čini odličnim prediktorom agresivnih formi papilarnog karcinoma..."

"Matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) are molecules that can remodel the cellular microenvironment and are necessary for maintaining tissue homeostasis. Inadequate regulation of these processes leads to many pathological conditions, including the formation and progression of malignant diseases. Thyroid carcinoma is the most frequent endocrine malignancy with increasing incidence over recent years worldwide. Neoplastic transformation of thyroid epithelial tissue potentially gives rise to many malignant and benign tumors with great diversity in clinical pesentation, aggressiveness and outcome. The limited possibility of predicting the development of unfavorable and metastatic features in thyroid carcinoma is currently one of the major problems in clinical practice and patient management. The aim of this thesis was to investigate the expression and activity of two metalloproteinases, MMP-2 and MMP-9, as well as their inhibitor, TIMP-2, as markers that might be helpful in differential diagnostics of thyroid neoplasia and prognostic stratification of patients. The analysis included archival and fresh tissue obtained by surgical removal from patients with benign or malignant thyroid tumors, while “healthy” peritumoral tissue was used as the control. Methods of analysis included immunohistochemistry and gelatin zymography (SDS-PAGE and in situ). The immunohistochemical analysis revealed that MMP-2, MMP-9 and TIMP-2 are expressed more strongly in papillary thyroid carcinoma than in follicular thyroid adenoma, follicular thyroid carcinoma and conditionally healthy thyroid tissue, which administers additional information during routine morphological tissue analysis. Comparison of MMP-2 immunohistochemical expression with clinicopathological data revealed a significant correlation with the presence of metastases in lymph nodes, while the expression profile of TIMP-2 was correlated with clinicopathological parameters involved in papillary carcinoma progression (tumor size and occurrence of extrathyroid invasion). The immunohistochemically detected active form of MMP-9 was strongly associated with most clinicopathological parameters of papillary carcinoma: tumor size, extrathyroid invasion and lymph node metastasis, cancer stage and depth of neoplastic infiltration. This makes this molecule an excellent predictor of aggressive forms of papillary carcinoma."

"Цикорија (Cichorium intybus L.) је традиционално коришћена лековита биљка богата гвајанолидима - биоактивним сесквитерпенским лактонима. У овом истраживању цикорија је трансформисана уз помоћ Agrobacterium rhizogenes, ради евалуације продукције гвајанолида у трансгеним културама коренова и регенерисаним биљкама, и испитивања утицаја флоралне транзиције и експресије бактеријских онкогена на акумулацију ових једињења. A. rhizogenes сој A4M70GUS je успешно трансформисао цикорију, дајући HR културе из којих спонтано регенеришу изданци, а регенеранти цветају in vitro. Код регенерисаних трансгених биљака, гвајанолиди се акумулирају у току флоралне транзиције, што није случај у нетрансформисаним биљкама. Акумулација ових једињења била је посебно изражена у корену трансформаната, што је корелисало са повишеном експресијом RolC гена. Гвајанолиди потичу од заједничког прекурсора - гермакрена А, који настаје дејством гермакрен А синтазе (GAS). У следећем кораку биосинтезе, гермакрен А оксидаза (GAO) у неколико корака преводи гермакрен А до гермакрен А киселине, од које настаје костунолид - прекурсор осталих сесквитерпенских лактона. GAS РНК цикорије је претходно изолована у краћој и дужој форми - CiGASlo (GAS long) и CiGASsh (GAS short). Из BAC библиотеке цикорије је изолован један промотор за GAS long, два промотора за GAS short и један за GAO, који су фузионисани са флуоресцентним репортером GFP. Функционалност и јачина промотора је праћена агроинфилтрацијом на зеленој салати и стабилном котрансформацијом цикорије A4M70GUS сојем са унетим конструктима. Као репортер за котрансформацију је коришћен други флуоресцентни маркер, DsRED. Услед инкомпатибилности коришћених флуоресцентних репортера DsRED и GFP, активност промотора у регенерисаним трансгеним биљкама је детектована RT-PCR и qRT-PCR техникама. Промотори су се одликовали различитом јачином и делимичном ткивном специфичношћу..."

"Chicory (Cichorium intybus L.) is traditionally used medicinal plant rich in guaianolides - bioactive sesquiterpene lactones. In this research, chicory was transformed with Agrobacterium rhizogenes in order to evaluate the production of guaianolides in transgenic root cultures and regenerated plants, and to explore the influence of floral transition and bacterial oncogene expression on guaianolide accumulation. A. rhizogenes strain A4M70GUS was successfully used for chicory transformation, producing hairy root cultures, which spontaneously regenerated shoots and plants that were flowering in vitro. In transgenic plants, guaianolides were accumulated during floral transition, which was not the case in untransformed plants. Accumulation of these compounds was especially significant in transformed plants' roots, which correlated with the expression of RolC gene. Guaianolides originate from a common precursor - germacrene A, which is synthesized by germacrene A synthase (GAS). In subsequent steps, germacrene A is converted to germacrene A acid in a series of steps catalyzed by germacrene A oxidase (GAO), which is then converted into costunolide - precursor of other sesquiterpene lactones. Two GAS mRNAs have been previously isolated from chicory - CiGASlo (GAS long) and CiGASsh (GAS short). One promoter for GAS long, two for GAS short and one promoter for GAO have been isolated from chicory BAC library, and fused with a fluorescent reporter GFP. Strength and functionality of the promoters were characterized by lettuce agroinfiltration and by cotransformation of chicory by A4M70GUS strain containing the constructs. DsRED, another fluorescent reporter, was used as a marker for cotransformation. Due to incompatibility of DsRED and GFP, promoter activity was detected in regenerated transgenic plants by RT-PCR and qRT-PCR. The promoters were characterized by different strength and partial tissue specificity. GAS long promoter was less tissue specific than GAS short, which was active mainly in chicory roots..."

"Dobijanje novih kultivara mandarina na klasičan način je izuzetno spor i dug proces zbog nemogućnosti da se prevaziđu problemi vezani za reproduktivnu biologiju mandarina kao što su apomiksija (nucelarna poliembrionija), seksualna nekompatibilnost i dug juvenilni period. U novije vreme, da bi se prevazišli ovi problem, primenjuju se dve savremene metode koje su postale neizostavni deo programa oplemenjivanja mandarina - somatska hibridizacija (fuzija protoplasta) i interploidno seksualno ukrštanje. Obe metode su bazirane na izmeni ploidnosti postojećih kultivara. Primenom somatske hibridizacije, u prvom koraku moguće je dobiti tetraploidne hibride sa kumulativnim roditeljskim kombinacijama genoma koje određuju nasleđivanje kvalitetnih osobina oba diploidna roditelja. Dobijeni tetraploidni somatski hibridi mogu dalje, u drugom koraku, da se koriste u interploidnom seksualnom ukrštanju sa izabranim diploidnim, komercijalno važnim kultivarima u cilju dobijanja triploidnih hibrida. Triploidne hibridne biljke uvek daju bezsemene plodove što je najvažniji cilj programa za oplemenjivanje mandarina. Pored bezsemenosti, postoje i drugi ne manje značajni ciljevi, u programu oplemenjivanja mandarina kao što su lako ljuštenje, produženje sezone plodonošenja, poboljšanje ukusa ploda, poboljšanje kvaliteta isceđenog soka, produženje dužine trajanja svežine ploda na policama prodavnica, otpornost na niske temperature i bolesti. Kompleksni sistem oplemenjivanja koji uključuje ove dve savremene biotehnološke metode je već bio primenjen na druge pripadnike roda Citrus, a u ovoj doktorskoj disertaciji je primenjen za oplemenjivanje mandarina koje se gaje na Floridi. U prvom delu disertacije su prikazani rezultati somatske hibridizacije gde je dobijeno 65 somatskih hibrida. Somatski hibridi su dobijeni kroz “hemijsku“ fuziju protoplasta izolovanih iz embriogenog nucelarnog kalusa i mezofila listova uz primenu polietilenglikola (PEG). Nivo ploidnosti regenerisanih hibrida je utvrđen metodom “flow” citometrije. Dobijeni somatski hibridi su bili rezultat hibridizacije šest roditeljskih kombinacija koje uključuju šest diploidnih roditelja – kultivara/selekcija sa vrhunskim kvalitetom ploda: tri mandarine [‘Ponkan’ (C. reticulata Blanco), ‘Willowleaf’ (C. deliciosa Tenore) i ‘Kinnow’ (‘King’ tangor (C. nobilis Lour.) × ‘Willowleaf’ mandarina (C. deliciosa Tenore))] i tri tangora [‘Murcott’ (C. reticulata Blanco x C. sinensis Osbeck), ‘W.Murcott’ (C. reticulata Blanco x C. sinensis Osbeck) i ‘Snack’ (C. reticulata Blanco × C. sinensis Osbeck)]. Regenerisane biljčice koje su aklimatizovane i gajene dalje u uslovima staklenika su testirane molekularnom markerima, primenom “expressed sequence tag – simple sequence repeat (EST-SSR)“ metode, da bi se utvrdila komplementarnost genoma dobijenih somatskih hibrida i njihovih roditelja. Uz pomoć EST-SSR markera je dokazano da su 46 somatskih hibrida autotetraploidi, 18 alotetraploidi a za jedan somatski hibrid nije bilo moguće odrediti genetičko poreklo. U grupi autotetraploida sa udvojenim genomom jednog od roditelja, 20 biljaka je imalo SSR alelske profile koji su bili potpuno podudarni sa alelskim profilom genoma tog roditelja..."

"Development of improved cultivars through conventional hybridization in mandarins has been hampered by several characteristics of their reproductive biology, mainly apomixis (nucellar polyembriony), sexual incompatibility, and long juvenility. As an alternative, two unconventional methods - somatic hybridization via protoplast fusion and interploid sexual hybridization have become integral part of mandarin variety improvements programs worldwide since they can easily overcome mentioned limitations of reproductive biology characteristics. Both techniques are based on ploidy manipulation. By using somatic hybridization, it is possible to produce novel germplasm at tetraploid level that combines all the good qualities of fused diploid selections. Used further in interpoid sexual hybridization, these newly produced somatic hybrids crossed with selected diploid commercial cultivars could generate eventually triploid hybrids. Triploid hybrids always produce seedless fruit which is a primary objective of mandarin breeding program. Besides seedlessness, there are other main breeding objectives for mandarins: easy-peel fruit, extension of the season of availability (early and late), improved flavor, juice quality, shelf life, cold hardiness, and disease resistance. This complex system of two unconventional biotechnological methods, used to generate triploid hybrids in other citrus species, was successfully applied in this thesis for mandarin cultivar improvement in Florida. In the first part of the thesis, a total of 65 somatic hybrids were obtained via somatic hybridization. They were produced by using chemically (polyethylene glycol - PEG) induced fusion of embryogenic suspensionderived protoplasts with leaf-derived protoplasts. “Flow” citometry was used to determine ploidy level of regenerated somatic hybrids. Somatic hybrids came from six different parental combinations involving six diploid parents - cultivars/selections with exceptional fruit qualities: three mandarins [‘Ponkan’ (C. reticulata Blanco), ‘Willowleaf’ (C. deliciosa Tenore), and ‘Kinnow’ (‘King’ tangor (C. nobilis Lour.) × ‘Willowleaf’ mandarina (C. deliciosa Tenore))] and three tangors [‘Murcott’ (C. reticulata Blanco × C. sinensis Osbeck), ‘W.Murcott’ (C. reticulata Blanco × C. sinensis Osbeck), and ‘Snack’ (C. reticulata Blanco × C. sinensis Osbeck)]. Produced plants, that survived in vitro conditions and aclimation in the greenhouse, were tested with expressed sequence tag – simple sequence repeat (EST-SSR) marker analysis to examine complementation of their nuclear genomes with their parental genomes. ESTSSR markers identified 46 autotetraploid plants, 18 allotetraploid plants, and one undefined plant. In autotetraploid group, 20 plants had SSR profiles completely matching the allelic profiles of one of their parents’ genomes but in duplicate. Following plants were autotetraploids of their female parents: ‘Murcott’, ‘W.Murcott’, and ‘Ponkan’ and in one case the plant was autotetraploid of ‘Willowleaf’ male parent. All other autotetraploid plants (26) had a duplicate genome of their female parent ‘W.Murcott’, except that EST-SSR markers did not completely match their maternal genome. Further testing with EST-SSR markers of some ‘W.Murcott’ callus lines derived from individual ovules discovered unexpected zygotic origin of several lines which were presumed to be of nucellar origin..."

"Prirodni izolat BGRA43, izolovan iz gastrointestinalnog trakta čoveka, determinisan je na osnovu klasičnih mikrobioloških i molekularno-bioloških metoda kao vrsta Lactobacillus helveticus. Soj poseduje jedan plazmid (pRA1), veličine 2.4 kb, koji se stabilno održava u ćeliji i nakon 10 sukcesivnih presejavanja. Za potrebe genetičkih manipulacija soj je uspešno transformisan plazmidom pA1-6, mada je efikasnost transformacije niska. Optimalna temperatura za rast ovog soja je 42oC, pri čemu je pokazano da soj dobro raste kako u MRS-u tako i u 10% obranom mleku. Nakon 6 sati rasta u 10% obranom mleku na temperaturi od 37oC dolazi do obaranja pH vrednosti u mleku na 4.53 pri čemu takodje dolazi do formiranja homogenog gruša visokog stepena viskoznosti. Soj BGRA43 pokazuje antimikrobijalnu aktivnost na veći broj Gram-pozitivnih i Gram-negativnih bakterija. Takodje je utvrdjeno da soj BGRA43 poseduje ekstracelularnu proteinazu. Cele ćelije ovog soja hidrolizuju sve tri glavne kazeinske frakcije u Na-fosfatnom puferu pH 6.5 i temperaturi od 45oC za samo 2 h. Proteolitička aktivnost soja BGRA43 inhibirana je inhibitorom serinskih proteaza (PMSF). Oslobadjanje proteinaze soja BGRA43 sa ćelijskog zida nije zavisno od Ca++-jona. Na osnovu DNK-DNK hibridizacija, PCR analize kao i sekvenciranjem kloniranog PCR produkta koji odgovara katalitičkom regionu proteinaze utvrdjen je visok stepen homologije sa ptrH genom iz soja Lactobacillus helveticus CNRZ32. Izolovan je i okarakterisan spontani Prt- derivat soja BGRA43, označen kao BGRA433. Derivat BGRA433 nije hidrolizovao ni jednu kazeinsku frakciju i pokazano je da poseduje deleciju u katalitičkom regionu proteinaznog gena. Ćelije soja BGRA43 preživljavaju u visokom procentu u uslovima niske pH vrednosti kao i u prisustvu 0.3% žučnih soli. Humano poreklo, široki spektar antimikrobijalnog delovanja i sposobnost preživljavanja u uslovima koji vladaju u gastrointestinalnom traktu čine soj BGRA43 potencijalnim probiotikom. Lactobacillus helveticus BGRA43 je uspešno iskorišćen i kao starter kultura za proizvodnju jogurta i kiselog mleka."

"Natural isolate BGRA43 was isolated from the human intestinal tract. Using the microbiology and molecular biology tests this thermophilic human isolate was determined as Lactobacillus helveticus. The strain BGRA43 was transformed with plasmid pA1-6, but efficiency of transformation was very low. It was found that BGRA43 contains only one small plasmid pRA1 about 2.4 kb. The strain BGRA43 grow very fast in milk (6h, pH 4.5) as well as in MRS (A600nm, 0.858, 10h). Growth of Lactobacillus helveticus BGRA43 in non-fat skim milk after 6 h at 37oC resulted in a lowering of the pH value to 4.53. Besides the fast acidification, the strain generated a high viscosity of skim milk. The strain BGRA43 produced antagonistic substances against both Gram-positive and Gram-negative bacteria and also exhibited an inhibitory effect on the growth of Clostridium sporogenes. Determination of caseinolytic activity done under optimal conditions (pH 6.5 and 45oC), revealed that proteinase from this strain completely hydrolysed all three casein fractions. The proteolytic activity of whole cells was inhibited by serine proteinase inhibitor (PMSF), suggesting that BGRA43 strain produce serine-type of proteinase. In addition, release of the proteinase from the cell envelope of strain BGRA43 is not Ca++-dependent. DNA-DNA hybridisation, PCR analysis and analysis of subcloning PCR fragments from catalytic region of proteinase showed high similarity (98.9% identity) with prtH gene isolated from Lactobacillus helveticus CNRZ32. Spontaneous Prt- derivative BGRA433 was isolated. This derivative is not able to hydrolyse any of casein fractions and hybridisation and PCR analysis showed deletion in catalytic region of proteinase gene. Human origin, antimicrobial activity and surviving at low pH and in presence of bile salts are all properties that consider this strain to be a potential probiotic. Finally, it was demonstrated that the strain BGRA43 can be very attractive as starter culture for production of fermented milk product."

"Ispitivanje je obuhvatilo velik broj podataka, kako literaturnih tako i terenskih, u pogledu nalaza proučavanih vrsta. Uočena je prostorna distribucija i odnosi između vrsta, pri čemu je zabeleženo širenje vrste T. fluviatilis u velikim nizijskim rekama, kao i znatno šire rasprostranjenje vrsta T. danubialis i T. transversalis u prošlosti. Rečni nerit je danas dominantan nerit u potamon-tpu reka Panonske nizije ovog područja. Bosanske reke Una Sana I Vrbas su potencijalni koridori za širenje vrste T. fluviatilis, i povezivanje njenog panonskog i dalmatinskog areala Pojedini stariji nalazi ove vrste, u rekama van pomenutog tipa, u skladu sa rezultatima ovog istraživanja bi zahtevali proveru, obzirom na mogućnost pogrešne identifikacije. Rasprostranjenje T. transversalis, je pretrpelo i najveće promene, odnosno drastično smanjenje samog areala vrste. U prošlosti su zabeleženi su nalazi sa nekoliko mesta na Dunavu, od Novog Sada, preko Đerdapa do ušća Timoka. Sem toga postoje nalazi i sa nekih drugih reka (Sava, Moravica). Naše istraživanje sugeriše da je i dalje prisutan, ali vrlo redak na Dunavu u ovom delu njegovog toka. Lokalitet na kome je nađen, Stari Slankamen može biti jedno od retkih utočišta retke vrste u ovom delu Dunava. Treba naglasiti i nalaze po jedne jedinke sa Tise (Martonoš) i Crnog Timoka (Zaječar), koji takođe mogu ukazivati na prisustvo populacija ovih puževa. Recentna distribucija pokazuje da je rečni sistem Velika Morava – Južna Moorava – Nišava glavni refugijum za retku vrstu T. transversalis. Bosanske reke Una Sana I Vrbas su potencijalni koridori za širenje vrste T. fluviatilis, i povezivanje njenog panonskog i dalmatinskog areala. Rezultati izvedene analize, potvrđuju opšte preference ovih vrsta u odnosu na tip reke, pa su tako vrste T. danubialis i T. transversalis najprisutnije u tipu 2 (velike reke van područja Panonske nizije), dok je T. fluviatilis dominantan u tipu 1 (velike nizijske reke). Ispitivanje odnosa sa setom fizičko-hemijskih parametara je pokazalo, da se, kao najvažniji faktori vode koji utiču na ispitivanu zajednicu teodoksusa mogu izdvojiti zasićenje vode kiseonikom, koncentracija ortofosfata i amonijum jona, te temperatura vode. Rezultati multivarijantne kanonijske analize dalje ukazuju na očekivanu veću toleranciju vrste T. fluviatilis na manju količinu rastvorenog kiseonika, više temperature, kao i na povećano prisustvo amonijuma u vodi. Druge dve vrste su osetljive na pomenute uslove, naročito T. danubialis. Kod najređe vrste T. transversalis, interesantna je ipak nešto povećana toleranca na sve pomenute faktore, pogotovo na povećane koncentracije ortofosfata, koje kako izgleda najbolje podnosi od ispitivanih vrsta..."

"The study includes a large number of data collected on the field, as well as the literature data. The spatial distribution and relationships between species are investigated. The spread and estabished dominance of T. fluviatilis in large lowland rivers, and much wider distribution of species T. danubialis i T. transversalis in the past were noted. Studied rivers Una, Sana and Vrbas are noted as potential corridors for the spread of T. fluviatilis, and connecting its Pannonian and Dalmatian range of distribution. It schould be mentioned that some of this species previous findings, apart of its typical habitats (potamon rivers) schould be rechecked. Distribution of T. transversalis, suffered the biggest change, resulting in a drastic reduction in its range. In the past, there have been records from several sites on the Danube, from Novi Sad through the Iron Gate to the mouth of the Timok River. Furthermore, reports were from other rivers ae well (the Sava River, the Moravica River). Despiteliterature data, the findings of this rare species in some localities in the Danube River suggests that it is still present but very rare. The site on which it is found (Stari Slankamen), could acts as one of the few remaining refugia for this rare species in the Danube. Findings from the Tisa River (Martonoš) and the Crni Timok River (Zaječar), schould be noted also. The analyses of its recent distribution showed that the Velika Morava River – Južna Morava River – Nišava River river system is the main refuga for the species. Results of preformed analysis have confirmed the general preferences of the species regarding the river type. Species T. danubialis i T. transversalis are the most present in river type 2 (large rivers outside of the Pannonian basin), while T. fluviatilis is dominant in river type 1 (large lowland rivers). Regarding its relation to water chemistry it has been showed that the most important of studied physico-chemical parameters on Theodoxus community were oxygen content, orthophosphates, ammona and water temperature. Multivariate analyzes indicate increased tolerance of T. fluviatilis to the low oxygen content and higher water temperature, as well as for increased ammona concentrations. Unlike the other two species are less tolerante to this conditions, especially T. danubialis. It is somewhat interesting that the rarest species T. transversalis has increased tolerance to organic nutrients (orthophosphates and nitrates)..."

"Ostracoda su jedna od najrasprostranjenijih grupa zglavkara. Prisutni u velikom broju različitih staništa i imaju najviše zabeleženih fosilnih nalaza. Rod Heterocypris Claus, 1982 ima kosmopolitsko rasprostranjenje i obuhvata 63 vrste. Prisustvo mešovite reprodukcije sa mogućnošću intra- i interspecijske hibridizacije doveli su do visoke genetičke i morfološke varijabilnosti unutar ovog roda. Taksonomija vrsta ovog roda se uglavnom zasniva na karakteristikama karapaksa, dok su razlike u strukturama na ekstremitetima malobrojne. Ova studija se bavi uporedno-morfološkom analizom karapaksa i mekih delova kod osam vrsta roda Heterocypris, sa ciljem da se uvedu dodatni morfološki karakteri i izvrši ocena postojećih karaktera. Razlike u obliku kapaka su analizirane kod 26 populacija iz Panonske nizije, Balkanskog poluostrva i Pirinejskog poluostrva. Deskriptivne obsevacije i morfometrijska analiza morfoloških karaktra karapaksa i mekih delova su date za 10 populacija. Geometrijskom analizom digitalizovanih kontura oblika kapaka u programu MORPHOMATICA, postignuta je ujednačenost deskripcije oblika kapaka i objektivniji pristup pri analizi intra i interspecijke varijabilnosti. Prvi put je sagledana intraspecijska varijabilnost i interspecijska diferencijacija morfoloških karakteristika gornje usne na vrstama roda Heterocypris, čime su konstatovani novi taksonomski karakteri. Prisustvo senzitivnog Wouters-organa na prvom segmentu antene kod svih analiziranih vrsta je takođe novi karakter konstatovan kod vrsta roda Heterocypris..."

"Ostracoda are one of the most common arthropod groups. They are found in a wide variety of environments, and they also have the most complete fossil record. The genus Heterocypris Claus, 1982 has a cosmopolitan distribution and comprises 63 species. The presence of mixed reproduction with possible intra- and interspecific hybridization has resulted in high genetic and morphological variability. The taxonomy of this genus is based mostly on carapace characteristics, while distinctive features of appendages are few. This study is based on comparative morphology of carapace and soft parts of eight species within the genus Heterocypris, with the aim of introducing additional morphological traits and reevaluating existing characters. Differences of valves shapes were analyzed in 26 populations from the Pannonian Plain, Balkan Peninsula and Iberian Peninsula. Descriptive observations and morphometric analysis of morphological traits of the carapace and soft parts are given for 18 populations. Geometric analysis of digitized valves outlines was performed in MORPHOMATICA software, providing balanced description of valve shapes and objective approach in analyses of intra- and interspecific variability. Specific differences morphological traits of the upper lip were ascertained for the first time for eight species of the genus Heterocypris, bringing new taxonomical characters. The presence of Wouters-organ on the first segment of antenna is also noted for the first time in Heterocypris species. Multivariate analysis of variance showed significant variation of morphometric characters of females among groups..."

"Ishrana bogata fruktozom predstavlja bitan faktor u razvoju metaboličkog sindroma koji je povezan sa povećanim rizikom za nastanak kardiovaskularnih bolesti. Smatra se da hronična inflamacija ima bitnu ulogu u njegovoj patogenezi. Ženke su zaštićene od ishranom izazvanih metaboličkih poremećaja i hipertenzije u reproduktivnom periodu. Estrogen, koji utiče na normalno funkcionisanje kardiovaskularnog sistema, bi mogao doprinositi uočenim polno specifičnim razlikama u nastanku simptoma metaboličkog sindroma. Proteinske komponente renin-angiotenzin sistema (RAS) imaju bitnu ulogu u nastanku inflamacije, hipertenzije i insulinske rezistencije i na njihovu ekspresiju utiče estradiol. Ova doktorska disertacija je za cilj imala da ispita da li pol i estradiol doprinose promenama u ekspresiji komponenti RAS-a [angiotenzin konvertujućeg enzima (ACE), angiotenzin konvertujućeg enzima 2 (ACE2), angiotenzinskog receptora tipa 1 (AT1R), angiotenzinskog receptora tipa 2 (AT2R) i kolektrina] i medijatora inflamacije i remodelovanja tkiva srca [nuklearnog faktora κB (NFκB), matriks metaloproteinaze-9 (MMP-9) i liganda 16 iz familije hemokina CXC (CXCL16)] kod animalnog modela metaboličkog sindroma. Mužjaci i ženke pacova koji su pili 10% rastvor fruktoze umesto vode u trajanju od 9 nedelja predstavljali su animalni model metaboličkog sindroma korišćen u ovoj studiji. Radi ispitivanja efekata estradiola jedan deo ženki pacova je ovarijektomisan i podeljen u tri grupe pri čemi je jedna grupa pored standardne laboratorijske hrane pila vodu, druga grupa je pila 10% rastvor fruktoze, a treća grupa je pored rasvora fruktoze primala i supstitucionu terapiju estradiolom. Ishrana bogata fruktozom je uzrokovala povećanje krvnog pritiska samo kod mužjaka pacova. Ovaj tip ishrane nije doveo do promena u masi srca niti u odnosu masa srca/masa tela ni kod jednog pola, kao ni kod ovarijektomisanih životinja što ukazuje da se hipertrofija srca nije razvila..."

"Fructose rich diet (FRD) represents an important factor in the development of metabolic syndrome. Metabolic syndrome is associated with increased risk for cardiovascular diseases occurrence and chronic inflammation has a major role in its pathogenesis. Females are protected from diet-induced metabolic disturbances and hypertension in their reproductive period. Estrogen, which influences the cardiovascular system, could contribute to the observed gender-specific differences in the onset of metabolic syndrome. Components of the renin-angiotensin system (RAS), the synthesis of which is mediated by estrogen, have an important role in the inflammatory processes, hypertension and insulin resistance. Almost all of the components of metabolic syndrome increase the activity of RAS, which finally results in increased oxidative stress and inflammation. The aim of this doctoral dissertation was to investigate sex specific changes and role of estradiol in the expression of RAS components [angiotensin converting enzyme (ACE), angiotensin converting enzyme 2 (ACE2), angiotensin receptor type 1 (AT1R), angiotensin receptor type 2 (AT2R) and collectrin], as well as mediators of inflammation and remodeling of heart tissue [nuclear faktor κB (NFκB), matrix metalloproteinse-9 (MMP-9) and CXCL16 chemokine] in the animal model of metabolic syndrome. Male and female rats, which consumed 10% fructose solution instead of water for 9 weeks, represent an animal model of metabolic syndrome that was used in this study. In order to examine the effects of estradiol in the context of FRD, female rats were ovariectomized and divided in three groups: fed normal diet, fed FRD, and fed FRD and subjected to estradiol replacement therapy. FRD increased blood pressure only in male rats. This diet regime didn't cause heart hypertrophy neither in intact males and females, nor in ovariectomized females..."

"Ekološki status akvatičnih ekosistema se određuje na osnovu bioloških, hidromorfoloških, hemijskih i fizičko-hemijskih elemenata kvaliteta. Najvažniji i najobuhvatniji dokument iz oblasti upravljanja, uređenja, zaštite i monitoringa akvatičnih ekosistema na području Evrope je Okvirna Direktiva Evropske Unije o vodama (Water Framework Directive -WFD). Države članice EU su već kreirale i uspostavile sisteme nacionalnog monitoringa i procene ekološkog statusa, od kojih su neki testirani na nivou većeg dela Evropskog kontinenta. Jedan od tih sistema, koji se bazira na kompoziciji i zastupljenosti akvatične vegetacije i čija je relevantnost testirana i potvrđena na području severne, zapadne i srednje Evrope je LEAFPACS metod. LEAFPACS predstavlja višemetrički sistem za procenu biološkog statusa akvatičnih ekosistema jezerskog tipa na osnovu stepena eutrofizacije, specijskog diverziteta i diverziteta životnih formi akvatičnih biljnih vrsta. Cilj ove disertcije je bila revizija klasifikacije akvatične i semiakvatične vegetacije, kao osnove za izradu vegetacisjke klasifikacije jezera i kalibracije LEAFPACS metode za područje Srbije, u skladu sa Okvirnom Direktivom EU o vodama. Terenska istraživanja akvatične i semiakvatične vegetaije, kao i fizičko-hemijska i hidromorfološka karakterizacija staništa su obavljeni na 31 jezeru, tokom letnjih meseci u periodi 2009-2011. godine. Od ukupno 31 istraživanog jezera, na 26 je konstatovana akvatična i semiakvatična vegetacija. Konstatovano je ukupno 97 biljnih vrsta, čija je relativna pokrovnost izračunata za svako jezero.

"The European Water Framework Directive (WFD) provides an opportunity to plan and deliver a better water environment, focusing on ecology. Aquatic macrophytes are considered one of the most reliable biological parameters for ecological status assessment under the WFD. These subjects were analysed at the wider European scale using LEAFPACS (Lake Assessment Methods, Macrophyte and Phytobenthos) method. LEAFPACS uses a suite of metrics for various pressures, including the LMNI index (Lake Macrophyte Nutrient Index). The LMNI index is based on Ellenberg Nutrient -N indicator values and has shown high applicability in lake eutrophication assessment. The aim of this study was to create a numerical classification of aquatic and semiaquatic vegetation and to describe a vegetation classification for lakes in Serbia based on LEAFPACS method. LEAFPASC sample quadrats, physic-chemical and hydromorphological parameters were collected during the summer months of 2009, 2010 and 2011 at 31 lakes in Serbia. Aquatic and semiaquatic vegetation was described for 26 lakes. A total of 97 species were identified, of which the most frequent were: Myriophyllum spicatum L., Phragmites australis (Cav.) Trin. ex Steud., Typha angustifolia L., Ceratophyllum demersum L. subsp demersum, Najas marina L. and Potamogeton nodosus Poir. According to physico-chemical parameters, lakes could be classified as high alkalinity lakes with moderate pH. TurboVeg database for aquatic and semiaquatic vegetation was created, compiling 1720 relevés, collected over the decades (1940-2010), and published by 24 authors in 38 papers, monographs, MSc and PhD theses. Most relevés are of Classes: Phragmitetea communis R. Tx. et Prsg. 1942, Potametea R. Tx. et Preising 1942 and Lemnetea minoris W. Koch et R. Tx. 1955; while most frequent Association are: Scirpo- Phragmitetum W. Koch 1926, Salvinio-Spirodeletum polyrrhizae Slavnić 1956 and Myriophyllo-Potametum Soo 1934. TWINSPAN analysis (Two-Way INdicator SPecies ANalysis) revealed two main lake vegetation types (TWI and TWII). TWII is characterized by typically species-rich, eutrophic sites with Ceratophyllum demersum L. subsp. demersum dominant, followed by Hydrocharis morsus-ranae L., Lemna minor L., Salvinia natans (L.)..."

"Zlatni šakal (Canis aureus L. 1758) je široko rasprostranjena vrsta iz porodice pasa. Spada u kanide srednje veličine tela sa izraženom socijalnom organizacijom. Centrom rasprostranjenja u evropskom delu areala se smatra Balkansko poluostrvo. Tokom novije istorije, areal šakala je u Evropi bio vrlo dinamičan. Prva polovina XX veka bila je u znaku neprestanog i veoma snažnog opadanja brojnosti populacija, kao i smanjivanja areala. Uzroci tako brzog nestajanja sa velikih prostranstava leže u brojnim akcijama trovanja (koje su naročito bile intenzivne u periodu nakon završetka II svetskog rata), kao i u prekomernom lovu i narušavanju staništa. Tokom poslednje dve decenije XX veka se povećava brojnost šakala koji šire svoj areal i rekolonizuju svoja prirodna staništa. Pored rekolonizacije, šakal se širi i na nove prostore koje istorijski nije naseljavao. Danas se vagrantne jedinke mogu naći i u pojedinim zamljama zapadne i severne Evrope. Trend širenja je zabeležen i u Srbiji gde je vrsta do kraja sedamdesetih godina prošlog veka praktično bila na rubu opstanka. Od osamdesetih godina, populacija počinje da se oporavlja i širi iz tri područja sa kojih nikad nije nestala: Srema, okoline Negotina i Bele Palanke. Brzina širenja populacija i uvećavanje areala, odnosno proces rekolonizacije je tako snažan da se može označiti kao ekspanzija. Danas se šakal može naći na preko 2/3 teritorije Srbije. Šakal je u Srbiji lovna vrsta i posmatrano prema odstrelu, najveće brojnosti se nalaze u području Negotinske Krajine, Pomoravlja, Donjeg Podunavlja i Srema. Sveobuhvatna istraživanja ekologije šakala u Srbiji su započeta 2003. godine na Biološkom fakultetu Univerziteta u Beogradu. Posebna pažnja je usmerena na istraživanja trofičke ekologije..."

"Golden jackal (Canis aureus L. 1758) is a widespread species of the dog family. It is a medium sized canid with a prominent social organization. Balkan Peninsula is considered the center of its distribution in the European part of the range. During recent history, jackal distribution in Europe has been very dynamic. The first half of the twentieth century was marked by constant and very strong decline in population number, as well as range reduction. The causes of the very rapid disappearance from vast areas are large poisoning activities (which were particularly intense in the period after the end of World War II), as well as over-hunting and habitat disruption. Jackal population number was increasing during the last two decades of the twentieth century, and jackals expanded their range and recolonized indigenous habitats. Moreover, jackals expanded into new areas that were not inhabited before by this species. Today, vagrant specimens can be found in some countries in western and northern Europe. The spreading of jackals was also recorded in Serbia where they were almost on the verge of extinction by the end of the 1970's. Since the 1980's, the population begins to recover and expand from three areas within which they have never disappeared: Srem region, Negotin area, and Bela Palanka. Rapid spread of populations and range increase, in fact the process of recolonization was so powerful that it could be designated as expansion. Today jackals are present on more than 2/3 of the territory of Serbia. Jackal is a hunting species in Serbia and according to hunting bag data, the largest populations are in the area of Negotinska Krajina, along Morava river, the Lower Danube, and Srem region..."

"Липосаркоми, тумори мезенхималног порекла, представљају најучесталији хистолошки тип саркома меких ткива. Групу карактерише велика разноликост како у погледу патохистолошке организације тумора тако и биологије понашања. Уобичајена подела липосаркома обухвата следећа три подтипа: а.) добро диферентовани / дедиферентовани, б.) миксоидни / округлоћелијски и в.) плеоморфни. С обзиром на значајне клиничко-патолошке разлике између три подтипа липосаркома, вероватно је да су различити механизми укључени у њихов настанак и развој. На основу студија које су се фокусирале на истраживање генетике саркома меких ткива и костију, може се закључити да сигнални путеви p53-p14 и Rb-p16 играју одређену улогу у свим типовима саркома. Разјашњавање улоге ових сигналних путева у патогенези липосаркома, може да буде допринос како дијагностици и прогностици липосаркома, тако и дефинисању потенцијалних терапеутских циљева. Студија је обухватила испитивање мутационог статуса гена р53 и метилационог статуса гена р14 и р16, на 33 узорка липосаркома, сва три подтипа. У циљу свеобухватније анализе испитивана је и експресија протеина р16, циклина D1 и фактора пролиферације Ki-67, применом имунохистохемијског бојења. Резултати експеримента су показали да промене у сигналним путевима р53-р14 и р16-Rb могу имати значаја у патогенези сва три подтипа липосаркома. Разлике се огледају у квалитету и квантитету промена."

"Liposarcoma, tumors of mesenchymal origin, represent the most frequent type of soft tissue sarcomas. The group is characterized by a great diversity regarding pathohistology and biological behavior. The group can be divided into three different subtypes: a.) well differentiated / dedifferentiated, b.) myxoid / round cell and c.) pleomorphic. Given the significant clinical and pathological differences between the three subtypes of liposarcoma, it is likely that different mechanisms are involved in their formation and development. Based on the studies that have been focused on genetic research of sarcoma of soft tissues and bones, conclusion can be drawn that the p53-p14 and Rb-p16 signaling pathways play a certain role in sarcomagenesis. Clarification of the role of these signaling pathways in the pathogenesis of liposarcoma, could be a contribution towards better diagnostic and prognostic criteria and the identification of potential therapeutic targets. The study included examination of the p53 gene mutation status and assessment of the p14/p16 gene methylation status in 33 liposarcoma samples of all three subtypes. For the purpose of more comprehensive analysis, protein expression of the p16, cyclin D1 and Ki-67 has been evaluated by immunohistochemical staining. The results of the study have showed that the alterations of the targeted signal pathways are important in the pathogenesis of all three subtypes of liposarcoma. The differences are reflected in the quality and quantity of the detected alterations."

"Zračenje indukuje povišenu ekspresiju receptora za epidermalni faktor rasta (EGFR). Polazeći od značaja EGFR signalnog puta u procesu tumorogeneze, ovaj receptor je postao važan ciljani molekul u terapiji tumora. Utvrđeno je da je on pojačano eksprimiran i u nesitnoćelijskom karcinomu pluća i da ima važnu ulogu u patogenezi i prognozi terapijskog ishoda ove bolesti. Erlotinib, inhibitor tirozin kinazne funkcije EGFR je jedan od prvih agenasa koji su uvedeni u ciljanu terapiju nesitnoćelijskog karcinoma pluća. S obzirom na navedeno, istraživanja sinergističkog delovanja erlotiniba i zračenja u cilju poboljšanja antitumorskog efekta ovih agenasa su veoma aktuelna. Mehanizmi koji se nalaze u osnovi kombinovane terapije i njenog uticaja na nastanak različitih tipova ćelijske smrti su još uvek nedovoljno istraženi. U ovoj disertaciji je in vitro ispitivan antitumorski efekat pojedinačnih i kombinovanih tretmana γ-zračenjem i erlotinibom na CRL-5876 ćelije nesitnoćelijskog karcinoma pluća čoveka. Efikasnost pojedinačnih i kombinovanih tremana na ćelijsko klonogeno preživljavanje, vijabilnost, proliferaciju, kao i na kinetiku nastanka i nestanka dvolančanih prekida na DNK i distribuciju ćelija po fazama ćelijskog ciklusa, praćena je u funkciji vremena. U okviru ove studije analizirani su i efekti navedenih tretmana na promenu morfologije i ultrastrukture ćelija. U cilju utvrđivanja tipova ćelijske smrti do kojih ovi agensi dovode i njihovog međusobnog odnosa, uveden je inhibitor autofagije, hlorokin. Na osnovu radiobioloških parametara utvrđeno je da CRL-5876 ćelije adenokarcinoma pluća čoveka pripadaju grupi radiorezistentnih tumorskih ćelija. Promene radiobioloških parametara nakon kombinovanog tretmana ukazuju da erlotinib značajno povećava radioosetljivost CRL-5876 ćelija. Ove promene su praćene i na nivou ćelijskog ciklusa.

"It is known that radiation therapy increases EGFR expression in cancer cells, thus promoting radioresistence. Considering the importance of EGFR signaling pathway in tumorigenesis, this receptor has become an important target molecule for the treatment of tumors. It has been shown that EGFR is frequently overexpressed in non-small cell lung cancer (NSCLC) and plays an important role in the pathogenesis and the prediction of the therapeutic outcome of the disease. Erlotinib inhibits the tyrosine kinase activity of the EGFR and is used in molecular targeted therapy of NSCLC. Given the above findings, combining radiation with erlotinib in order to boost antitumor effects of these agents represents an actual field of research. However, the mechanisms underlying combined therapy and its impact on the induction of different modes of cell death have not been fully explained. This theasis examines the antitumor effect of single and combined treatments with γ-rays and erlotinib on CRL-5876 human lung adenocarcinoma cells in vitro. The efficiency of single and combined treatments on clonogenic survival, cell viability, proliferation, kinetics of formation and disappearance of DNA double strand breaks and cell cycle distribution is monitored as a function of time. In this study the effects of these treatments on cell morphology and ultrastructure are analyzed. In order to determine the modes of cell death caused by these agents and to reveal their mutual relations, the autophagy inhibitor chloroquine is introduced in the analysis. Based on the radiobiological parameters it is found that CRL-5876 human lung adenocarcinoma cells belong to the radiorezistant group of cells. Changes in radiobiological parameters after combined treatments show that erlotinib significantly increases radiosensitivity of CRL-5876 cells. Moreover, changes in cell cycle distribution after treatments are observed. It is revealed that radiation causes G2/M arrest while erlotinib induces a decrease in S phase..."

"Urbana staništa su pod snažnim antropogenim uticajem i karakteriše ih intenzivno zagađenje vazduha, vode i zemljišta materijama poreklom iz različitih stacionarnih i mobilnih izvora. Specifična vrsta polutanata u ovim sredinama su metali koji se zbog svoje toksičnosti i biološke nerazgradivosti akumuliraju u zemljištu. Istraživanja u okviru ove disertacije su obavljena u urbanim parkovima u Pančevu, Smederevu, Obrenovcu i Beogradu koji su izloženi zagađivanju hemijskim elementima uključujući toksične metale poreklom iz različitih izvora. Obuhvatala su analize biljaka, kao i zemljišta na kojima rastu. Za ekofiziološka istraživanja odabrane su tri drvenaste vrste biljaka koje se dugi niz godina uspešno gaje na urbanim staništima: Pinus nigra Arn., Aesculus hippocastanum L. i Platanus acerifolia (Ait.) Willd. Osnovni cilj doktorske disertacije je bio definisanje faktora limitirajućih za razvoj biljaka, kao i ispitivanje njihovih ekofizioloških karakteristika i adaptivnog odgovora. Posebna pažnja je posvećena problemu zagađivanja metalima i metaloidima, njihovoj mobilnosti i dostupnosti biljkama, kao i njihovom uticaju na fiziološke procese u bilјkama (efikasnost fotosinteze i sadržaj fotosintetičkih pigmenata). Ispitivanja fizičko-hemijskih karakteristika zemljišta su pokazala da urbana zemljišta karakteriše visok udeo frakcije peska, nizak sadržaj higroskopne vlage, organskog ugljenika i azota, alkalna reakcija, ali i povoljan odnos C/N za mineralizaciju organske materije i oslobađanje minerala esencijalnih za biljke. Navedeni limitirajući faktori (toksičan sadržaj B, Cr, Ni i Pb izmerenih u zemljištu urbanih parkova) u sinergističkom delovanju sa visokim temperaturama i malom količinom padavina u značajnom delu ispitivane vegetacijske sezone su uticali na funkcionisanje ispitivanih vrsta biljaka na urbanim staništima. Analiza sadržaja hemijskih elemenata u četinama i listovima je pokazala da postoje razlike u sadržaju elemenata između vrsta, ali i da su ispitivane vrste izložene toksičnim koncentracijama B i Sr i istovremenom deficitu esencijalnih elemenata Cu, Mn i Zn. Generalno, kod P. nigra, A. hippocastanum i P. acerifolia postoje razlike u fotosintetičkoj efikasnosti, sadržaju pigmenata i u morfološkim oštećenjima listova. Uprkos navedenom, sve ispitivane vrste, pre svega listopadne A. hippocastanum i P. acerifolia su pokazale visok potencijal za toleranciju stresa zagađivanja toksičnim metalima i metaloidima, što ih čini pogodnim za sadnju u urbanim parkovima i industrijskim zonama, pa kao takve predstavlјaju značajan resurs za dalјa istraživanja."

"Urban habitats are under strong anthropogenic influence and are often characterized by intense air, water and soil pollution originating from various stationary and mobile sources. The specific type of pollutants in these habitats are metals that due to their toxic, persistent and nonbiodegradable properties accumulate in the soil. Research was conducted in urban parks in Pančevo, Smederevo, Obrenovac and Belgrade that are exposed to pollution by chemical elements, including toxic metals originating from various sources. Research included plant and soil analyses. For ecophysiological research, three woody plant species that have been successfully grown in urban areas were selected: Pinus nigra Arn., Aesculus hippocastanum L. i Platanus acerifolia (Ait.) Willd. The central aim and subject of this doctoral dissertation was to define the factors that limit the functioning of plants, and to determine their ecophysiological characteristics and adaptive responses. Special attention was paid to the problem of pollution by toxic metals and metalloids, their mobility and availability to plants, as well as their impact on physiological processes in plants (photosynthesis efficiency and photosynthetic pigment content). Analyses of the physical and chemical properties of the soils showed that urban soils are characterized by high proportion of a sand fraction, a low content of hygroscopic moisture, organic carbon and nitrogen and an alkaline reaction, but also a favorable C/N ratio for mineralization of organic matter and release of essential minerals for plants. The limiting factors (toxic levels of B, Cr, Ni and Pb measured in soils from urban parks) in synergy with high temperatures and low precipitation during a significant part of the vegetation season, influenced the functioning of the examined plant species in urban habitats. Analysis of the chemical element contents in pine needles and leaves revealed species differences, and also that the examined species were exposed to toxic concentrations of B and Sr and, at the same time, deficits of the essential elements, Cu, Mn and Zn. Generally, in P. nigra, A. hippocastanum and P. acerifolia, differences in photosynthetic efficiency, pigment contents and in morphological symptoms of injury were observed. In spite of the above, all the investigated species, first of all A. hippocastanum and P. acerifolia, exhibited a high potential for tolerance to stress pollution by toxic metals and metalloids, which makes them suitable for planting in urban parks and industrial zones. These species represent a significant resource for further research."

"Proučavanje akvatičnih oligoheta u tekućicama Srbije predstavlja doprinos izradi popisa celokupne faune Oligochaeta Srbije. Istraživanjem je obuhvaćeno deset rečnih slivova koji se prostiru na području južno od Dunava, uključujući i glavni tok Dunava koji protiče kroz Srbiju. Analizom materijala zabeležen je 61 takson iz 9 porodica, pri čemu je do nivoa vrste determinisano 56 taksona. Jedan rod i 11 vrsta konstatovano je po prvi put u tekućim vodama Srbije: Achaeta sp., Bothrioneurum vejdovskyanum, Chaetogaster langi, Cognettia sphagnetorum, Enchytraeus buchholzi, E. christenseni, Henlea ventriculosa, Marionina argentea, Potamothrix danubialis, P. heuscheri, P. moldaviensis i Vejdovskyella intermedia. Većina zabeleženih vrsta su česte i sa kosmopolitskim rasprostranjenjem. Tubificidae i Naididae su najznačajnije porodice u pogledu raznovrsnosti i uočene su u svim slivovima. U neposrednom slivu Dunava zabeležena je najveća raznovrsnost zajednice oligoheta (37 vrsta), zatim slede slivovi Zapadne Morave, Ibra i Kolubare sa po 27, 24 i 23 vrste, dok je najmanja raznovsrnost konstatovana u kanalima beogradskog regiona (10 vrsta). Diverzitet oligohetne faune pokazao je jasan obrazac – manja raznovrsnost uočena je u pritokama, a veća u glavnom toku. Najrasprostranjenija vrsta jeste Limnodrilus hoffmeisteri sa učestalošću pojavljivanja u uzorcima F=0,51, a značajnu zastupljenost ima i Stilodrilus heringianus (F=0,33). Dva roda i deset vrsta konstatovano je samo na po jednom lokalitetu (Acheta sp., Fridericia sp., Chaetogaster diaphanus, Ch. limnaei, Dero dorsalis, Nais simplex, Uncinais uncinata, Vejdovskyella intermedia, Potamothrix heuscheri, Spirosperma ferox, Cognettia sphagnetorum i Rhynchelmis limosella) sa frekvencijom F=0,004. Ekološkom analizom zajednica oligoheta u tekućicama Srbije uočeno je da je najviše zabeleženo potamalnih vrsta, većina je adaptirana finom supstratu – mulj, glina i sitan pesak, i većina vrsta su tolerantne na povećano organsko opterećenje (alfamezosaprobna i beta-mezosaprobna grupa)..."

"The study of aquatic Oligochaeta in freshwaters in Serbia represents a contribution to the development of the entire oligochaetan fauna inventory of Serbia. The investigation included ten river basins that cover the area south of the Danube River, including the stretch of the Danube that flows through Serbia. In total, 61 taxa from nine families were recorded and 56 taxa were identified to the species level. One genus and eleven species were noted for the first time in the running waters of Serbia: Achaeta sp., Bothrioneurum vejdovskyanum, Chaetogaster langi, Cognettia sphagnetorum, Enchytraeus buchholzi, E. christenseni, Henlea ventriculosa, Marionina argentea, Potamothrix danubialis, P. heuscheri, P. moldaviensis, and Vejdovskyella intermedia. The majority of the identified species are frequent and cosmopolitan. In terms of the species richness, the most dominant families were Tubificidae and Naidiae and they were recorded in all investigated river basins. The highest species richness was observed in the Danube catchment area (37 species), followed by the Zapadna Morava, Ibar, and Kolubara basins (27, 24, and 23 species, respectively), while the lowest was recorded in the channels of the Belgrade region (10 species). The composition of the oligochaetan community showed a clear pattern – lower diversity in tributaries, higher diversity in the main flow. The most frequent species in Oligochaeta assemblages was Limnodrilus hoffmeisteri (F=0,51), but Stilodrilus heringianus also showed a significant occurrence (F=0,33). Two genus and ten species were recorded at only one locality each with frequency of F=0,004 (Acheta sp., Fridericia sp., Chaetogaster diaphanus, Ch. limnaei, Dero dorsalis, Nais simplex, Uncinais uncinata, Vejdovskyella intermedia, Potamothrix heuscheri, Spirosperma ferox, Cognettia sphagnetorum and Rhynchelmis limosella)..."

"Farmakogenomika proučava odnos između genetičkog sklopa individue i njegovog odgovora na lekove i jedan je od stubova personalizovane medicine. Dosadašnji princip lečenja da se standardna doza leka daje svim pacijentima sa istom dijagnozom po unapred utvrđenom protokolu se napušta. Za veliki broj pacijenta ta doza leka često nije efikasna i/ili sigurna za upotrebu. Cilj farmakogenomičkih studija je da identifikuju farmakogenomičke markere, varijacije u genomu koje mogu pouzdano da predvide odgovor na terapiju, što je osnov za individualizaciju terapije. Model sistemi bolesti za analizu farmakogenomičkih markera korišćeni u ovom radu su dečja akutna limfoblastna leukemija (ALL) i reumatoidni artritis (RA). Lečenje ovih bolesti uključuje imunosupresivne i citotoksične lekove 6-merkaptopurin (6-MP), metotreksat (MTX), antibiotik baktrim, antimikotik nistatin, kao i anti-TNF lekove. Genetičke varijacije koje modulišu metaboličke puteve povezane sa ovim lekovima su kandidati za farmakogenomičke markere. Cilj ove studije je da ispita učestalosti genetičkih varijanti u genima TPMT, ITPA, ABCB1, ABCC4, TYMS, MTHFR, SLC19A1, DHFR, TNF i IL-6, kao i da oceni farmakogenomički potencijal ovih varijanti u srpskoj populaciji. Biće ispitana i uloga ovih farmakogenomičkih markera kao faktora rizika za razvoj dečje ALL. Ispitaće se i uticaj terapije održavanja, gde okosnicu terapije čine lekovi 6-MP i MTX, kao i pola i uzrasta dece sa ALL na ekspresiju gena TPMT. Biće funkcionalno okarakterisane varijante u genu TPMT, potencijalni modulatori ekspresije gena TPMT, sa posebnom pažnjom na ulogu VNTR regiona u promotoru gena TPMT. U studiju je bilo uključeno 174 pedijatrijskih ALL pacijenata, 73 RA pacijenata i 104 kontrolnih zdravih ispitanika. Genetičke varijacije u svim gorepomenutim genima su određene metodama baziranim na PCR-u..."

"Pharmacogenomics is focused on exploring the relation between the genomic signature of an individual and their drug response. It is the basis for implementation of personalized medicine. The old-fashioned therapeutic paradigm of »one protocol dose fits all patients with the same diagnosis« is getting abandoned. The standard drug dose is often not efficient and/or safe for many of patients. Pharmacogenomic studies identify pharmacogenomic markers, genomic variations that could reliably predict the drug response, which is the basis for therapy individualization. In order to analyze pharmacogenomic markers, childhood acute lymphoblastic leukemia (ALL) and rheumatoid arthritis (RA) are used as disease model systems. ALL and RA therapy protocols include cytotoxic and immunosuppressive drugs 6-mercaptopurine (6-MP) and methotrexate (MTX), antibiotic bactrim and antimycotic nystatin, as well as anti-TNF drugs. Genetic variations that modulate metabolic pathways related to these drugs are candidate pharmacogenomic markers. The aim of this study is to analyze frequencies of genetic variants in TPMT, ITPA, ABCB1, ABCC4, TYMS, MTHFR, SLC19A1, DHFR, TNF and IL-6 genes in Serbian population and to evaluate the pharmacogenomic potential of these variants. Also, the role of these pharmacogenomic markers as risk factors for development of childhood ALL will be assessed. Influence of the maintenance therapy, which includes 6-MP and MTX as most important drugs, as well as the age and gender of patients will be analyzed in regard to TPMT gene expression. Functional assays will be carried out in order to identify potential modifiers of TPMT expression with a special focus on VNTR region in promoter of TPMT gene. In this study, 174 pediatric ALL patients, 73 RA patients and 104 healthy subjects were enrolled. Genetic variants in above-mentioned genes were detected using PCR-based methodology..."

"Predmet disertacije je efikasna nelinearna analiza okvirnih konstrukcija grednim konačnim elementima sa težištem na modeliranju materijalnih nelinearnosti. Geometrijska nelinearnost se uzima u obzir poznatim metodama. U tezi su analizirana i unapređena dva gredna konačna elementa: fiber element i element koncentrisane plastičnosti i napisan je sopstveni kompjuterski program kojim su elementi implementirani u postojeći open-source program za analizu konstrukcija – FEDEASLab. Tokom rada na tezi, ostvareni su sledeći ciljevi. Izvršena je optimizacija integracije poprečnog preseka čeličnih i armirano-betonskih elemenata u cilju poboljšanja efikasnosti fiber elemenata kako pri cikličnom pseudo-statičkom opterećenju, tako i pri nelinearnoj dinamičkoj analizi pojedinih delova i čitave konstrukcije. Formulisana su praktična pravila i definisane jasne smernice za diskretizaciju poprečnog preseka čeličnog I profila i pravougaonog armiranobetonskog preseka, u zavisnosti od vrste analize koja se sprovodi i željene tačnosti. Razvijen je novi konačni elementa iz grupe elemenata koncentrisane plastičnosti koji prevazilazi ograničenja postojećeg elasto-plastičnog elementa kao što su nemogućnost opisivanja postepene plastifikacije poprečnog preseka i opisivanja ponašanja materijala sa ojačanjem. Pri tome, element je zadržao svoju veliku kompjutersku efikasnost koja je osnovna prednost elemenata koncentrisane plastičnosti. Za određivanje stanja elementa razvijena su dva algoritma prema “general closest point projection” i “convex cutting plane” return mapping algoritmima i analizirana je zavisnost konvergencije od implementiranog algoritma. Mogućnosti novog elementa za modeliranje okvirnih konstrukcija pri delovanju statičkog i dinamičkog opterećenja su potvrđene kroz niz numeričkih primera. Specijalna pažnja je posvećena primeni novog GP elementa za modeliranje CFT stubova spregnutih konstrukcija..."

"The objective of this study is the efficient nonlinear analysis of space frames with beam/column finite elements considering material nonlinearity. Geometric nonlinearity is taken into account using known methods. Two different nonlinear beam/column elements are analyzed and improved: a fiber element and a concentrated plasticity element. Own computer code is written and implemented into the existing matlab toolbox for nonlinear structural analysis – FEDEASLab. During this study, the following objectives are achieved. By the optimization of the number and position of material integration points at monitored steel and reinforced concrete cross-sections, the significant improvement in efficiency of the fiber beam-column element under cyclic static and dynamic loading conditions is gained. The practical rules for an efficient discretization of steel wide-flange sections and rectangular reinforced-concrete sections are defined, depending on the desired level of accuracy and the type of analysis. In addition, the new three-dimensional nonlinear beam-column element is formulated. The element is of concentrated plasticity type and overcomes the common limitations of the existing elasto-plastic elements, such as the inability to describe gradual plastification of a cross-section and the hardening behavior. Also, the element keeps its high computational efficiency which is one benefit of concentrated plasticity elements. Two algorithms for element state determination are developed in accordance with the general closest point and convex cutting plane return mapping algorithms. Their influence on element convergation is studied. The ability of the element to simulate frame behavior is confirmed on a number of numerical examples. The special attention is devoted to model CFT composite column behavior..."

"Recikliranje betonskog otpada je jedno od održivih rešenja za rastuće probleme sa deponijama građevinskog otpada i nekontrolisano iskorišćavanje prirodnih resursa. Rezultat procesa je agregat od recikliranog betona koji se trenutno dominantno koristi za podloge puteva i nekonstruktivne betonske elemente. Sa stanovišta zaštite resursa, smanjenja energije i razvoja ekološke svesti, važno je istražiti da li se beton na bazi recikliranog agregata može koristiti za elemente armiranobetonskih konstrukcija. Predmet istraživanja u ovoj disertaciji su elementi konstrukcije, tačnije gredni nosači napravljeni od betona na bazi recikliranog agregata (RAC) i njihovo ponašanje pod dejstvom kratkotrajnog opterećenja do loma savijanjem ili smicanjem. Formirana je baza podataka i obavljena statistička analiza o mehaničkim svojstvima RAC betona u odnosu na uporedne betone sa prirodnim agregatom (NAC). Eksperimentalni rad obuhvatio je ispitivanje recikliranog agregata, betona na bazi recikliranog agregata i grednih nosača napravljenih od takvog betona. Rezultati ispitivanja svojstava agregata i probna ispitivanja fizičko-mehaničkih svojstava serija RAC i NAC betona poslužili su kao ulazni parametar za projektovanje sastava 3 betonske mešavine sa 0%, 50% i 100% recikliranog agregata krupne frakcije, iste projektovane čvrstoće pri pritisku. Ukupno je do loma ispitano 18 greda, statičkog sistema prosta greda, raspona 3.0 m. Od toga, napravljene su 3 serije od po 3 grede sa različitom količinom podužne armature (0.28%, 1.46% i 2.54%). Koncept ispitivanja postavljen je tako da se faznim povećanjem opterećenja dođe do loma nosača usled savijanja u sredini raspona. Takođe, napravljene su 3 serije od po 3 grede od betona sa 0%, 50% i 100% krupnog RAC i sa različitom količinom poprečne armature (0%, 0.14% i 0.19%), predviđenih za ispitivanje smičuće nosivosti. Izvršeno je poređenje zavisnosti sila-pomeranje, slika prslina, ugiba, dilatacija u betonu i armaturi, oblika loma i graničnih nosivosti greda od klasičnog i RAC betona, bazirano na sopstvenim i drugim rezultatima ispitivanja. Testirana je mogućnost primene savremenih propisa koji se odnose na NAC betone na gredne RAC elemente, kroz poređenje analitičkih predikcija i eksperimentalnih vrednosti momenta savijanja pri pojavi prve prsline, ugiba, graničnih momenata savijanja i granične smičuće sile. Takođe, izvršeno je poređenje sopstvenih i drugih rezultata eksperimentalnih ispitivanja osnovnih parametara nosivosti greda koje su dominantno izložene savijanju ili smicanju..."

"Recycling of waste concrete is one of the sustainable solutions for the growing waste disposal crisis and depletion of natural aggregate sources. As a result, recycled concrete aggregate (RCA) is produced, and so far it has mostly been used in low-value applications such as for the pavement base. But, from the standpoint of promoting resource and energy savings and environmental preservation, it is essential to study whether a concrete made of recycled aggregates - recycled aggregate concrete (RAC) can be effectively used as a structural material. Structural reinforced concrete elements were in the focus of this investigation, i.e. beam girders made of RAC and their behaviour up to flexural and shear failure under short-time loading. A very wide data base was formed and statistic analysis of relations between mechanical properties of RAC and corresponding natural aggregate concrete (NAC) was performed. The experimental research consisted of investigations of recycled concrete aggregate, recycled aggregate concrete and structural behaviour of beams made of RAC. Test results of RCA investigation and trial investigations of physical and mechanical properties of RAC were used as basic parameters for the design of 3 concrete mixtures with 0%, 50% i 100% of coarse RCA with the same compressive strength. Full-scale tests were performed on 18 simply supported beams with span of 3.0 m until the failure load due to flexure or shear was reached. Firstly, three series of beams made of three types of concrete and different ratio of flexural reinforcement (0.28%, 1.46% and 2.54%) were formed. Experiment on beams was performed by increasing the load level until flexural failure in the middle of span occurred. Furthermore, three series of beams with different ratio of shear reinforcement (0%, 0.14% i 0.19%) and concrete with 0%, 50% and 100% of coarse RCA were prepared to examine shear behavior. Comparison of load-deflection behavior, crack patterns, service deflections, strains in concrete and reinforcement, failure modes and ultimate flexural and shear capacity of NAC and RAC beams was made. The possibility of using equations from NAC codes to RAC beams was tested by comparison of an analytical expressions and experimental results related to cracking moments, deflections, ultimate bending moments and ultimate shear capacity. The analysis of own and other authors’ test results was performed both on flexural and shear behavior of RAC reinforced concrete beams..."

"Protrombin (Faktor II) je prekursor trombina, jednog od ključnih molekula u održanju hemostazne ravnoteže. Njegov povišeni nivo dovodi do odstupanja od hemostazne ravnoteže u smeru hiperkoagulacije i shodno tome predstavlja faktor rizika za pojavu tromboza. Kod pacijenata sa povišenim nivoom protrombina identifikovano je prisustvo G u A polimorfizma na 20210. mestu u 3’ nekodirajućem regionu gena (FII G20210A). Istraživanja su pokazala da 3’ kraj gena za protrombin ima nekanononsku organizaciju, a za G20210A polimorfizam je dokazano da dovodi do povišene ekspresije protrombina, što za posledicu ima pojavu tromboza. Međutim, precizan mehanizam kojim ovaj \"3' gain of function\" polimorfizam utiče na ekspresiju gena i dovodi do povišenog nivoa proteina još uvek nije rasvetljen. Obzirom da brojni pacijenati imaju povišeni nivo protrombina u plazmi, a ne nose G20210A polimorfizam, pretpostavlja se da u 3’ kraju gena postoje i drugi polimorfizami koji mogu da utiču na ekspresiju protrombina. Novija istraživanja ukazuju da je učešće 3’ kraja u regulaciji ekspresije gena daleko kompleksnije nego što se pretpostavljalo i da se u okviru ovog regiona nalazi veliki broj potencijalnih regulatornih elemenata. U okviru ovog istraživanja urađena je strukturna i funkconalna analiza 3’ kraj gena za protrombin koja je imala za cilj da rasvetli mehanizme kojima 3’ kraj gena za protrombin i polimorfizmi u okviru njega, utiču na ekspresiju protrombina i patogenezu trombofilije. Strukturna analiza je obuhvatila pretraživanje 3’ kraja kod pacijenata sa povišenim nivoom protrombina i identifikovana su tri nova polimorfizma: T20063C, C20068T i T20298C. Za ova tri polimorfizma kao i dva polimorfizma (A19911G i C20221T) koji su u literaturi već povezivana sa patogenezom trombofilije, određena je učestalost u grupi od 100 pacijenata sa trombofilijom i u kontrolnoj grupi od 100 zdravih ispitanika. Za A19911G polimorfizam u homozigotnom obliku (OR 1,27, p=0,603) i C20068T polimorfizam u heterozigotnom obliku (OR 2,14, p=0,687) je pokazano da su učestaliji u grupu pacijenta u odnosu na kontrolnu grupu, dok C20221T, T20063C i T20298C polimorfizmi nisu detektovani ni kod jednog od ukupno 200 ispitanika. U ovoj studiji je po prvi put, opisan somatski mozaicizam za G20210A polimorfizam i otvoreno pitanje uloge mozaicizma u nastanku multifaktorijalnih bolesti. Funkcionalna analiza je pokazala da konstrukat sa C20068T polimorfizmom ima 1,64 puta povećanu ekspresiju u odnosu na wt (wild type) konstrukt (p0,05), dok je za kontrukt sa T20063C polimorfizmom dokazano da nema razlike u ekspresiji u odnosu na wt. Pokazano je da prisustvo dela 3’FR (flanking region) sekvence u kojoj se nalazi DSE (downstream sequence element) regulatorni region dovodi do smanjenja ekspresije protrombina. To smanjenje je najizraženije kada se porede dva wt konstrukta, a najmanje kada je u konstruktima prisutan 20068T polimorfizam. Pokazano je, da je prisustvo dela 3’ FR sekvence sa DSE regionom neophodno da bi G20210A polimorfizam doveo do povećane ekspresije protrombinskog gena. Takođe, identifikovan je region u poslednjem egzonu gena za protrombin koji može biti potenicijalno značajan u regulaciji ekspresije. Na osnovu rezultata ove studije, jedan od novodetektovanih polimorfizama u 3’ kraju gena za protrombin-C20068T, predstavlja potencijalno značajan marker trombofilije. Dobijeni rezultati ukazuju da deo 3’ FR sekvence, koja sadrži DSE element, igra važnu ulogu u regulaciji ekspresije gena za protrombin i da postoji složena interakcija između ovog regulatornog elementa i polimorfizma u 3’ kraju gena za protrombin, koju je potrebno dalje istraživati."

"Prothrombin (Factor II) is a precursor of thrombin, and one of the key enzymes involved in blood coagulation. Hyperprothrombinemia leads to hypercoagulability and increased thrombosis risk.The G to A substitution at position 20210 of the 3’ untranslated region of (UTR) the factor II gene (FII G20210A) is associated with increased prothrombin level and enhanced blood coagulation. A recent studies of 3’ end of FII gene identified an unusual architecture of noncanonical sequence elements. However, the precise mechanism by which G20210A 3’ gain of function polymorphism affects gene expression and leads to elevated levels of protein remains unsolved. The elevated prothrombin level is, also, present in patients, non-carriers of G20210A polymorphism, indicating the presence of additional 3’ end polymorphisms in prothrombin gene. 3’ end of the gene and its impact on regulation of gene expression are far less studied in relation to the 5 'end and promoter, although recent research suggests that this region might have an important role in the gene expression regulation. The aim of our study was to elucidate the mechanism by which 3’ end of prothrombin gene, as well as polymorphisms in this region, affect the prothrombin gene expression and pathogenesis of thrombophilia. Screening of 3’ end of prothrombin gene in patients with thrombophilia identified three new polymorphisms: T20063C, C20068T, and T20298C. In order to examine the role of these three and two previously described polymorphisms (A19911G and C20221T) in pathogeneses of thrombophilia a case-control study was carried out in a group of 100 thrombophilic patients and 100 healthy blood donors. The homozygous carriers for A19911G polymorphism (OR 1.27, p = 0.603) and heterozygous carriers for C20068T polymorphism (OR 2.14, p = 0.687) were more frequent in the patient group compared to the controls, while C20221T, T20063C and T20298C polymorphisms were not detected. For the first time, we described somatic mosaicism for G20210A polymorphism and open the question of possible role of mosaicism in the pathogenesis of multocaftorial diseases. Functional assays revealed that constructs with the C20068T polymorphism increased expression level 1.64 times compared to the wild type construct (p <0.05), while construct with T20063C polymorphism showed no difference in expression. We have shown that the presence of 3'FR (flanking region) sequence with the DSE (downstream sequence element) in constructs leads to decreased prothrombin expression. Our results, also showed that DSE element is necessary for gain of function effect of prothrombin G20210A polymorhism. We have identified a last exon region of prothrombin gene which may play role in regulation of prothrombin expression. Our results showed that C20068T polymorphism may be a potentially important marker for thrombophilia. Also, our findings suggest that DSE region within 3’ FR sequence of prothrombin gene, might have an important role in the regulation of gene expression. It is obvious that complex interactions between polymorphisms and regulatory elements in 3’ end of prothrombin gene exist, which needs further investigations."

"Aktivacija mikroglije jedno je od glavnih obeležja eksperimentalnog autoimunskog encefalomijelitisa (EAE) i drugih neuroloških poremećaja koje odlikuje hronična inflamacija. Cilj ove studije bio je da se proceni sposobnost dva analoga purinskih nukleozida, ribavirina (RBV) i tiazofurina (TR), da modulišu inflamatorni odgovor aktivirane mikroglije, in vivo i in vitro. U in vivo studiji, koja je izvedena na EAE modelu indukovanom ubrzgavanjem encefalitogene emulzije u šapu Dark Agouti pacova, pokazano je da tretman životinja kombinacijom oba analoga, počev od pojave prvih simptoma pa tokom sledećih 15 dana, dovodi do smanjenja težine bolesti, a na histološkom planu do smanjenja broja i stepena aktivacije mikroglije. Budući da kombinovani tretman RBV i TR dovodi do supresije simptoma EAE i do redukcije reaktivne mikroglioze, formulisana je hipoteza da ovaj tretman, pored ranije opisanih sistemskih efekata u imunskom i vaskularnom sistemu, ostvaruju centralni efekat i to delujući prvenstveno na ćelije mikroglije. Uticaj RBV i TR, kao i kombinovane primene oba analoga detaljnije je ispitan u primarnoj kulturi mikroglijskih ćelija. Aktivacija mikroglije, indukovana lipopolisaharidom bakterijskog zida gram negativnih bakterija, (LPS), izazvala je tipičan odgovor reaktivne mikroglioze. Antiinflamatorni potencijal RBV, TR i RBV+TR ispitan je u pogledu citotoksičnosti, indukcije morfoloških promena, produkcije azot monoksida (NO), oslobađanja proinflamatornih citokina i nuklearne translokacije NF-κB. Ispitan je citototoksični potencijal RBV (1 – 20 μM), TR (1 – 20 μM) i kombinovanog tretmana (10 μM RBV + 5 μM TR) i određene su EC50 doze pri kojima se postiže polovina maksimalnog citotoksičnog efekta. RBV, TR i kombinovani tretman smanjuju ukupnu produkciju NO u kulturi stimulisanoj LPS-om, a taj efekat se pripisuje smanjenju ukupnog broja ćelija u kulturi. RBV, TR i RBV+TR menjaju ameboidnu morfologiju aktivirane mikroglije, tako što smanjuju prosečnu površinu ćelija u kulturi. Tretman RBV, TR i RBV+TR smanjuju translokaciju NF-κB/p65 u jedro. Primenjeni tretmani smanjuju ukupno oslobađanje TNF-α i IL-6, što je verovatno posledica smanjenja ukupnog broja aktiviranih ćelija, a RBV i kombinovani tretman povećavaju ekspresiju IL-1β. U primarnoj kulturi mikroglijskih ćelija potvrđena je genska i proteinska ekspresija uravnotežujućih nukleozidnih transportera 1 i 2 (ENT1, 2), koji učestvuju u transportu RBV i TR u ćelije. Ukupno gledano, rezultati dobijeni ovom studijom ukazuju da RBV i TR, pojedinačno ili u kombinaciji, deluju citotoksično na aktiviranu mikrogliju i menjaju njenu morfologiju, a ispoljavaju i imunomodulatorno dejstvo tako što snižavaju produkciju NO, smanjuju signalizaciju posredovanu NF-κB/p65 i redukuju produkciju proinflamatornih citokina."

"Activation of microglia is the hallmark of experimental autoimmune encephalomyelitis (EAE) and other neurodegenerative disorders associated with chronic neuroinflammation. The present study addressed the potency of purine nucleoside analogues ribavirin (RBV) and tiazofurin (TR) to modulate the microglial inflammatory response in vivo and in vitro. In this study, we induced animal model of multiple sclerosis – experimental autoimmune encephalomyelitis (EAE) by subcutaneous injection of encephalitogenic emulsion in the hind paw of Dark Agouti rats and showed that therapeutic treatment of EAE animals with combination of these two nucleoside analogues reduced disease severity. In addition, histological analysis indicated that RBV and TR also decreased the number and activation status of microglial cells. Since the combined treatment with RBV and TR leads to suppression of EAE symptoms and reduction of reactive microgliosis, we proposed hypothesis that this treatment, in addition to previously described effects in immune and vascular system, may act in central nervous system targeting primarily microglial cells. Therefore, in further experiments we examined effect of RBV, TR and their combination (RBV+TR) on primary microglial cell culture. Activation of microglial cells with bacterial lipopolysaccharide (LPS) triggers typical microglial responses to inflammation. Anti-inflammatory potential of RBV, TR and RBV+TR was tested in terms of influencing microglial morphological changes, NO production, nuclear factor-κB translocation and proinflammatory cytokines release, after LPS stimulation. The cytotoxic effects of RBV (1 – 20 μM), TR (1 – 20 μM) and their combination (10 μM RBV + 5 μM TR) are determined, as well as the dosages that achieved half-maximal inhibitory effect (EC50). RBV, TR and combination treatment lowered NO levels in LPS stimulated cultures as a result of decreased cell number. RBV, TR and RBV+TR induced shrinkage of average cell surface of LPS activated amoeboid microglial cells. Treatment with RBV, TR and RBV+TR of activated microglia strongly reduced the nuclear translocation of NF-κB/p65 and suppressed proinflammatory immune response genes. Applied treatments also exerted suppression of TNF-α and IL-6 release in activated microglia manly by reduction of cell number. At the same time, RBV and RBV + TR treatment additionally increased LPS-induced IL-1β gene expression and release. In primary microglial cell culture, gained results confirmed gene and protein expression of equilibrative nucleoside transporters (ENTs), proteins that are responsible for the putative entry of RBV and TR into cells. Results obtained in this study indicate that RBV and TR, alone or in a combination, attenuate neuroinflammatory response, probably by exerting cytotoxicity on activated microglial cells, reduction of NO levels, attenuation NF-κB signaling and decrease of proinflammatory cytokine release."

"Napredni biomaterijali na bazi NiTi i CuAlNi legura koje memorišu oblik (SMA) su vrlo atraktivni za izradu biomedicinskih implantata i uređaja. Međutim, biokompatibilnost NiTi i CuAlNi legura proizvedenih konvencionalnim metodama je često loša usled njihove neodgovarajuće površinske mikrostrukture koja omogućava oslobađanje metalnih jona u okolni medijum. U ovom radu je primenjen nov metod sinteze brzo stvrdnutih (RS) SMA valjanjem rastopine. Biokompatibilnost i imunomodulacijske osobine SMA legura su ispitane na modelima peritoneumskih makrofaga pacova (PMØ) i humanih dendritskih ćelija monocitnog porekla (DC), i na humanim mononuklearima periferne krvi (PBMC) izolovanim iz 20 različitih donora. Pokazano je da RS SMA, za razliku od kontrolnih SMA pripremljenih konvencionalnim metodama istog sastava, ne ispoljavaju citotoksičnost prema ispitivanim ćelijama. Osnovni razlog tome je što je na površini RS SMA formiran tanak homogeni sloj oksida koji štiti SMA od korozije, a inkubiranjem u medijumu dolazi do njegovog zadebljavanja. Međutim, pokazano je da CuAlNi RS SMA stimulišu produkciju IL-6 i izazivaju oksidativni stres kod PMØ, ali ne menjaju produkciju proinflamacijskih citokina u većini kultura PBMC stimulisanih mitogenom. Sa druge strane, NiTi RS SMA stimulišu produkciju IL-10 u 25% kultura stimulisanih kultura PBMC. U skladu sa tim je pokazano da NiTi RS SMA stimulišu fenotipsko sazrevanje DC koje produkuju veći nivo IL-10 i IL-27, i stimulišu produkciju IL-10 i TGF-β u ko-kulturi sa CD4+T ćelijama. Međutim, DC kultivisane na NiTi RS SMA u prisustvu LPS-a poseduju veći alostimulatorni kapacitet i stimulišu Th1 imunski odgovor in vitro. Ovi rezultati ukazuju na to da se RS SMA mogu bezbedno iskoristiti kao implantati kod većine pacijenata, ali je neophodno razmotriti i da li bi imunomodulacijske osobine ovih legura mogle izazvati neželjene posledice kod nekih pacijenta. Nanočestice zlata (GNP) su vrlo atraktivne za primenu u dijagnostici i fototermalnoj terapiji tumora. Međutim, njihova biokompatibilnost i imunomodulacijske osobine nisu dovoljno ispitane, što je neophodno za njihovu bezbednu primenu u biomedicini. U ovom radu je primenjen nov metod sinteze GNP ultrasoničnom sprej pirolizom (USP). Pri tome je sintetisano 5 različitih frakcija GNP različitih mikrostrukturnih odlika..."

"Advanced biomaterials based on NiTi CuAlNi shape memory alloys (SMAs) are very attractive for the production of biomedical implants and devices. However, the biocompatibility of NiTi and CuAlNi alloys, prepared by conventional methods, is often poor due to their inadequate surface microstructure causing the release of toxic metal ions into the surrounding medium. Therefore, we applied a novel method for the preparation of SMAs using Rapid Solidification (RS) via Melt-Spinning. Biocompatibility and immunomodulatory properties of SMA alloys were studied using the in vitro models of rat’s peritoneal macrophages (PMØs), human monocyte-derived dendritic cells (DCs), and mitogen-stimulated human peripheral blood mononuclear cells (PBMCs) isolated from 20 different donors. It was shown that RS SMAs, in contrast to control SMAs of the same composition but prepared by conventional methods, do not exhibit cytotoxicity towards the tested cells. The main reason for this phenomenon is the formation of a thin homogeneous oxide layer on the surface of RS SMAs that protects the SMAs from corrosion, and the conditioning in cell culture medium leads to its thickening. However, CuAlNi RS SMAs induce the production of IL-6, cause oxidative stress in PMØ, but do not modify the production of pro-inflammatory cytokines in most of the mitogen-stimulated PBMCs cultures. In contrast, NiTi RS SMAs stimulate the production of IL-10 in 25 % of the stimulated PBMC cultures. Accordingly, we showed that NiTi RS SMAs stimulate the phenotypic maturation of DCs, which produce higher levels of IL-10 and IL-27, and stimulate the production of IL-10 and TGF-β in co-culture with CD4+ T cells. However, in the presence of LPS, DCs cultivated on RS NiTi SMA possess a stronger allostimulatory capacity, and potentiate the development of Th1 immune response in vitro. These results indicate that RS SMAs can be safely used as implants for most patients, but special care should be taken as to whether the immunomodulatory properties of these alloys would cause some adverse effects in some patients. Gold nanoparticles (GNP) are quite promising for the use in diagnostics and photo-thermal cancer therapy. However, their biocompatibility and immunomodulatory properties have not been investigated sufficiently for their safe use in biomedicine..."

"Ekspresija receptora za estrogen (ER) i receptora za progesteron (PR) je preduslov hormonske zavisnosti karcinoma dojke. Hormonski receptori su još uvek jedni od najpouzdanijih parametara prognoze i predikcije ovog karcinoma, mada su klinički ishod pacijentkinja i odgovor na hormonsku terapiju varijabilni. Uključivanje receptora za humani epidermalni faktor rasta 2 (HER2) u klasifikaciju karcinoma dojke zajedno sa hormonskim receptorima, samo je donekle doprinelo utvrđivanju preciznijeg prognostičkog profila, što je ukazalo na potrebu za traženjem dodatnih, selektivnijih markera prognoze i predikcije. Prognostički značaj potencijalnih biomarkera se najbolje sagledava praćenjem prirodnog toka bolesti tj. toka bolesti koji nije bio prekidan adjuvantnom (postoperativnom) terapijom. O prirodnom toku bolesti karcinoma dojke ima vrlo malo literaturnih podataka s obzirom da se u savremenoj kliničkoj praksi svim pacijentkinjama daje neki oblik adjuvantne terapije. Literaturni podaci ukazuju na značaj interleukina 8 (IL8) i matriksnih metaloproteinaza 2 i 9 (MMP2, MMP9) kao potencijalnih biomarkera prognoze i predikcije u različitim tipovima humanih kancera. Studije koje se odnose na hormonsku regulaciju ekspresije ovih potencijalnih biomarkera u karcinomu dojke su kontroverzne. Više studija je ukazalo da bi ovi biomarkeri mogli biti potencijalni indikatori rezistencije na hormonsku terapiju. Ciljevi: Ciljevi istraživanja su bili: da se ispita prognostički i prediktivni značaj kliničkopatoloških parametara i odabranih biomarkera (IL8, MMP2, MMP9); da se proceni da li i na koji način interakcije između ER, PR i HER2 kao glavnih determinanti karcinoma dojke, imaju uticaja na ekspresiju odabranih biomarkera; da se proceni eventualno postojanje sprege između odabranih biomarkera, što bi moglo doprineti razumevanju progresije hormonski zavisnog karcinoma dojke i objašnjenju rezistencije na hormonsku terapiju..."

"Expression of estrogen receptor (ER) as well as progesterone receptor (PR) is the prerequisite of hormonal dependence of breast cancer. Hormone receptors are still among the most reliable prognostic and predictive parameters of this cancer, although the clinical outcome of patients and the response to hormonal therapy are variable. Inclusion of human epidermal growth factor receptor 2 (HER2) in the classification of breast cancer together with hormone receptors, only partly contributed to the determination of more precise prognostic profile, which pointed out the need for searching additional, more selective prognostic and predictive markers. The best way to evaluate the prognostic significance of potential biomarkers is by following the natural course of the disease – the course that hadn’t been interrupted by adjuvant (postoperative) therapy. Very few literature data is available regarding this issue as some kind of adjuvant therapy is given to all breast cancer patients nowadays. Literature data have indicated the significance of interleukin 8 (IL8) and matrix metalloproteinase 2 and 9 (MMP2, MMP9) as potential prognostic and predictive biomarkers in different types of human cancers. Available data regarding hormonal regulation of expression of these potential biomarkers in breast cancer are controversal. Many studies have indicated that these biomarkers could be potential indicators of resistance to hormonal therapy. Aims: The aims of this study were: to evaluate the prognostic and predictive significance of clinicopathological parameters and selected biomarkers (IL8, MMP2, MMP9); to examine if and how interactions among ER, PR and HER2 as the main determinants of breast cancer influence the expression of selected biomarkers; to examine the possible existence of feedback between selected biomarkers, which might contribute to understanding of progression of hormone dependent breast cancer as well as to the explaination of resistance to hormonal therapy..."

"Proizvodjac aminoglikozidnog antibiotika G-52, Micromonospora zionensis, poseduje sgm gen koji kodira 16$ rRNK metilazu cijom se ak'uvnoscu ostvaruje rezistencija na 4,6-disupstituisane dezoksistreptaminske aminoglikozide. Identifikovana su dva promotora uzvodno od kodirajuce sekvence sgm gena. Jedan promoter je reiativno slab i on otpocinje transkripciju od G nukleotida koji se nalazi 72 bp uzvodno od translacionog start kodona (ATG). Drug: promotor je mnogo jaci i Iociran je na vecoj udaljenosti od ATG kodona (~250 nukleotida). Postojanje ovih tandemskih promotora bi moglo da omoguci diferencijalnu gensku ekspresiju pa je postulirana njihova razlicita funkcija kod proizvodjaca. Tako 1e predlozeno da je slabiji P1 promoter odgovoran za konstitutivnu transkripciju sgm gena, dok je P2 zaduzen za ekspresiju nizvodnih (biosintetskih) gena u vreme kada otpocinje sinteza antibiotika. Prema tome, P2 promotor bi mogao biti potencijalno koristan za favorizovanu ekspresiju kloniranih gena u stacionarnoj fazi rasta micromonospora. Konstruisana je serija transkripcionih i translacionih sgm-Iacz genskih fuzija na plazmidu pPLti7G. Transkripcija obe vrste fuzija se odvija pod kontrolom snaznog PLtI promotora, posto promotori sgm gena nisu funkcionalni u bakteriji E. coli. Nivo ekspresiie lacZ gena u pojedinim transformantima sa transkripcionim ili translacionim fuzijama odredjivan je merenjem B-galaktozidazne aktivnosti. Transformanti sa translacionom fuznjom koji imaju i ekstra kopiju sgm gena bilo u cis iii u trans poziciji, pokazuju izrazit pad B-galaktozidazne aktivnosti. U slicnim eksperimentima sa transkripcionim fuzijama nije uocen znacajan efekat ekstra kopije sgm gena. Ovi rezultati su pokazali da je ekspresija sgm gena autoregulisana transiacionom represijom, najverovatnije zbog vezivanja metilaze za sopstvenu iRNK. Ekspresijom sgm gena u razlicitim sojevima aktinomiceta utvrdjeno je da je visok nivo rezistenqije na higromicin B zaista determinisan sgm genom, ali da je ispoljavanje ove rezistencije zavisno od soja u kome se sgm gen eksprimira. Ovaj podatak sugerira na zakljucak da ispitivani sojevi mikromonospora poseduju identican mehanizam rezistencije na higromicin. Iz toga se moze zakljuciti da mikromonospore najverovatnije poseduju odredjenu specificnost u gradji male subjedinice ribozoma koja je. konzervirana medju sojevima ovog roda."

"The sisomicin-gentamicin resistance methylase (sgm) gene from Micromonospora zionensis (producer of 6-52antibiotic), encodes an enzyme thatmodifies 16S rRNA, and thereby conferring resistance to 4,6-disubstituted deoxystreptamine aminoglycosides. Two promoters were identified upstream of the sgm coding sequence. One promoter (Pi) is relatively weak and initiates transcription at the G which is 72 nucleotides upstream of the translational initiation codon (ATG). A second (P2) promoter is much stronger and is located more upstream from the ATG codon (~250 nucleotides). These tandem promoters could enable differential gene expression of the sgm gene, and it has been postulated that promoters have specialized functions in the producing organism. The apparent weak P1 promoter is probably responsible for constitutive transcription of the sgm gene, whereas the P2 promoter may play a specialized role in expressron of the downstream (biosynthetic) genes, during the time that the antibiotic (3-52 is produced. Therefore, P2 promoter could be potentially used in expressing cloned genes especially during the stationary growth phase of micromonospora. A set of transcriptional and translational fusions oi the sgm gene and the feel reporter gene have been constructed by using the pPLtl7G plasmid. Both transcriptional and translational fusions were transcribed under the strong PLtl promoter,since it has been shown that the sgm promoters are non-functional in E. coli. Transformants harbouring either the transcriptional and translational fusions were assayed for B-gaiactosidase activity. Translational fusion transformants which also carried an extra copy of sgm gene either in cis or in trans position, exhibited a substantial decrease in B-galactosidase activity. No significant effect was observed in comparable experiments with the transcriptional fusions. These results demonstrate that the expression of the sgm gene is regulated by translational autorepression, presumably due to methylase binding to the specific site/s on its own mFiNA. The translational repression model is discussed in light of overall control of the sgm gene expression. The expression of the sgm gene in various actinomycetes strains revealed that expression of high-level resistance to hygromycin B, determined by sgm gene, is background dependent. This evidence suggests that it may well be that ail tested micromonospora strains share a common mode of hygromycin B resistance. Factors that might be contributed to background-dependent expression of hygromycin B resistance are discussed."

"Uticaj heterogenih uslova svetlosti i antropogeno indukovanog stresa (gaženja i aerozagađenja) na oblik i veličinu lista Mercurialis perennis i delova cveta Iris pumila, procenjen je primenom geometrijske morfometrije. Takođe je proučavan i uticaj navedenih faktora na varijabilnost osobina izdanaka M. perennis (visine biljke, broja listova i broja internodija). S obzirom na to da je M. perennis dvodoma biljka, analizirano je i prisustvo polnog dimorfizma i potencijalnih polno–specifičnih reakcija na suboptimalne uslove staništa. Uticaj heterogenih uslova svetlosti i aerozagađenja na stepen integracije oblika različitih delova cveta I. pumila procenjivan je na osnovu obrazaca korelacionih odnosa. Biljne vrste M. perennis i I. pumila su se u dosadašnjim istraživanjima pokazale kao pogodni model–sistemi za istraživanja u oblasti evolucione biologije biljaka. Šumski prosinac, Mercurialis perennis L. (Euphorbiaceae), je dvodoma višegodišnja zeljasta biljka, karakteristična pre svega za stara šumska staništa, primarna ili manje narušena, ali se može naći i na otvorenim, kao i na staništima pod jakim antropogenim uticajem. Kao dvodoma vrsta, predstavlja atraktivan objekat za proučavanje različitih aspekata polnog dimorfizma kod biljaka. Patuljasta perunika, Iris pumila L. (Iridaceae), je višegodišnja monokotila iz grupe geofita, karakteristična je pre svega za otvorena, uglavnom suva nizijska do brdska staništa. U ovo istraživanje uključene su populacije M. perennis sa lokaliteta Avala i Bele stene (Kopaonik), kao i populacije I. pumila sa lokaliteta Deliblatska peščara i Beograd. Pored toga, analizirani su i cvetovi I. pumila gajeni u eksperimentalnim uslovima jasno definisanog intenziteta i kvaliteta svetlosti. Analizirano je 90 biljaka M. perennis i 120 biljaka (ukupno 60 genotipova) I. pumila sa prirodnih staništa izloženih heterogenim uslovima svetlosti, 170 biljaka (33 genotipa) I. pumila gajenih u eksperimentalnim uslovima pod različitim svetlosnim tretmanima, kao i 119 biljaka M. perennis i 120 biljaka (41 genotip) I. pumila sa staništa izloženih različitom nivou antropogeno indukovanog stresa..."

"Impact of heterogeneous light conditions and anthropogenically induced stress (trampling and air polluton) on shape and size of leaves in Mercurialis perennis and flower parts in Iris pumila, was assessed by means of geometric morphometrics. The effect of mentioned factors on variability of shoot traits in M. perennis (plant height, number of leaves and internodes) was also explored. Since M. perennis is a dioecious plant, presence of sexual dimorphism and potential sex–specific reaction to suboptimal habitat conditions was investigated. The effect of heterogeneous light conditions and air pollution on degree of integration of shape of different floral parts of I. pumila was determined based on changes in patterns of covariation among mentioned structures. Mercurialis perennis and Iris pumila have proved themselves to be suited model systems in plant evolutionary biology research. Dog`s mercury, Mercurialis perennis L. (Euphorbiaceae), is a dioecious perennial forb, typical of ancient undisturbed woodlands, but it can also occur in open conditions and under strong antropogenic disturbance. As a dioecious herb, it represents an attractive object for research of different aspects of sexual dimorphism in plants. Dwarf iris, Iris pumila L. (Iridaceae), is monocot, perennial, geophyte typically inhabiting open, dry lowlands. This research included M. perennis populations from Avala and Bele stene (Kopaonik) as well as I. pumila populations from Deliblato Sands and Belgrade. Additionally, flowers of I. pumila grown under experimentally explicitly manipulated light intensity and quality conditions were analyzed. The study included a total of 90 M. perennis and 120 I. pumila plants (sum 60 genotypes) from natural habitat exposed to heterogeneous light conditions, 170 I. pumila plants (33 genotypes) grown under different light experimental treatments, as well as 119 M. perennis and 120 I. pumila plants (41 genotypes) from sites exposed to different levels of anthropogenically induced stress..."

"Samoubilačko ponašanje predstavlja globalni zdravstveni problem s obzirom da oko milion ljudi godišnje izvrši samoubistvo, a efikasne mere prevencije ili lečenja ne postoje. Kao i drugi složeni fenotipovi, etiologija samoubilačkog ponašanja vezuje se za brojne genetičke i sredinske faktore rizika i njihove međusobne interakcije. Pokušaj samoubistva je često, ali ne i nužno, povezan sa psihijatrijskim oboljenjima i stresnim događajima tokom života, kao što su stresni događaji iz detinjstva i akutni stresni događaji. Neurobiološka istraživanja ukazuju na hipofunkciju serotoninskog sistema kod osoba sa samoubilačkim ponašanjem. Editovanje RNK deaminacijom adenozina u inozin, katalizovan enzimima ADAR i ADARB1, doprinosi finoj i dinamičnoj regulaciji i održavanju optimalne serotoninske transmisije kroz editovanje transkripata za triptofanhidroksilazu 2 (TPH2), enzima koji katalizuje sintezu serotonina u mozgu, i transkripata za postsinaptički serotoninski receptor 2C (HTR2C). Cilj ove doktorske teze je identifikacija varijanti u genima TPH2, HTR2C, ADAR i ADARB1, stresnih životnih događaja i njihovih međusobnih interakcija koje mogu napraviti razliku između psihijatrijskih bolesnika koji su pokušali samoubistvo i onih koji to nikada nisu uradili. Studija je uključila 353 psihijatrijska bolesnika sa dijagnozom depresivnog poremećaja, bipolarnog afektivnog poremećaja i shizofrenije, od kojih je 165 pokušalo samoubistvo, dok njih 188 nije. Stresni događaji iz detinjstva i akutni stresni događaji procenjeni su korišćenjem upitnika Early Trauma Inventory–Self Report i List of Threatening Experiences Questionnaire, redom. Primenom Pirsonovog 2–testa i logističke regresije testirane su potencijalne pojedinačne asocijacije stresnih događaja tokom detinjstva, akutnih stresnih događaja, 23 tag varijante gena ADAR i ADARB1, varijanta rs6318 gena HTR2C i varijante rs7305115 i rs4290270 gena TPH2 sa pokušajem samoubistva. Generalizovani linearni modeli i selekcija unazad primenjeni su za ispitivanje udruženih efekata pojedinačnih faktora i njihovih interakcija na rizik za pokušaj samoubistva, uključujući psihijatrijske dijagnoze, pol i starost bolesnika kao konfaunderi..."

"Suicidal behavior is a global health problem since about one million people per year commit suicide and there is no effective prevention or treatment. Like other complex phenotypes, etiology of suicidal behavior is associated with numerous genetic and environmental risk factors and their interactions. A suicide attempt is often, although not necessarily, associated with psychiatric disorders and stressful life events, such as childhood abuse and acute stressful life events. Neurobiological studies have indicated a hypofunction of the serotonin system in patients with suicidal behavior. RNA editing by deamination of adenosine to inosine, catalysed by ADAR and ADARB1 enzymes, contributes to fine and dynamic tuning and maintenance of an optimal serotonin transmission through the editing of transcripts encoded by the tryptophan-hydroxylase 2 (TPH2) and serotonin receptor 2C (HTR2C) genes. TPH2 is a rate limiting enzyme for serotonin synthesis in the brain, while HTR2C is a postsynaptic receptor. The aim of this doctoral thesis was to identify variants in the TPH2, HTR2C, ADAR and ADARB1 genes, individual stressful life events, and possible interaction among these factors that might help to differentiate between psychiatric patients who attempted suicide and those who did not. The study included 353 patients diagnosed with major depressive disorder, bipolar affective disorder and schizophrenia, of which 165 attempted suicide, while 188 did not. Childhood abuse and acute stressful life events were evaluated using the Early Trauma Inventory Self-Report questionnaire and the List of Threatening Experiences Questionnaire, respectively. Pearson’s 2–test and logistic regression were performed to test potential individual association of various domains of child abuse, acute stressful events, 23 ADAR and ADARB1 tag variants, HTR2C variant rs6318 and TPH2 variants rs7305115 and rs4290270 with attempted suicide. Generalized linear models and backward selection were applied to test the joint effect of individual and interacting effects of examined factors on suicide attempt, including psychiatric diagnoses, patients’ gender and age as potential confounders..."

"Изазови повезани са стањем животне средине и климатским променама значајно повећавају потребу различитих дисциплина за адекватним подацима и информацијама које имају просторну и временску димензију. Ове потребе се могу задовољити искључиво кроз програме оперативног мониторина земљишта који укључују картирање земљишног покривача. Оперативни систем за мониторинг земљишта захтева интегрисано коришћење прикупљених података, њихову ефикасну и континуирану трансформацију у корисне стандардизоване и правовремене информације, њихову асимилацију у моделе и њихово коришћење у проценама, креирању политике и системима за подршку одлучивању. Тренутно доминантна парадигма картирања земљишног покривача се заснива на системима квалитативне класификације при чему се простор дели у ентитете који се придужују класама из претходно установљеног система класификације. Основни проблем традиционалних методологија картирања земљишног покривача лежи у чињеници да су изведене информације, као производ класификације, подложне концептуализацији како креатора тако и корисника при чему се често ове концептуализације не поклапају. Хармонизације и стандардизације картирања земљишног покривача као покушаји да се дође до јединствене концептуалне равни не могу суштински да премосте овај проблем. Решење се може тражити у квантитативном моделирању земљишног покривача. Предмет истраживања ове дисертације представљају концепт, захтеви и могућности квантитативног картографског моделирања земљишног покривача у условима изражене потребе за одговарајућим, квалитетним и ажурним информацијама о животној средини и природним ресурсима. Како оптички сателитски сензори представљају основни извор података за генерисање информација о земљишном покривачу, истраживање је фокусирано на квалитет података сателитског осматрања Земље као и квалитет метода моделирања квантитативних параметара које служе за описивање карактеристика појава земљишног покривача. Као средства квантитативног описивања основних категорија земљишног покривача: вегетације, воде, земљишта и вештачких површина, анализирани су у пракси најчешће коришћени спектрални индекси и биофизички параметри. Спектрални индекси су погодни у квантитативном моделирању јер су директна функција сателитских података, али како они не представљају апсолутне биофизичке карактеристике појава, њихова интерпретација је често проблематична, посебно при описивању вегетације као најкомплексније категорије. Са друге стране, моделирање биофизичких параметара представља изазов. Једноставни емпиријски модели оцене биофизичких параметара из спектралних индекса оптерећени су значајном несигурношћу због чега нису погодни за оперативну употребу. Детерминистички (физички) модели оцене биофизичких параметара представљају добру теоријску основу за оперативно картирање, али је потребно познавање њихове несигурности. Посебан фокус је стављен на експериментално испитивање несигурности физички моделираних биофизичких параметара за описивање вегетације као најкомплексније категорије земљишног покривача и то у зависности од различитих извора несигурности..."

"Challenges related to environment and climate changes significantly increase demands of various disciplines for appropriate data and information that are spatial in nature. These needs can be fulfilled only through the programmes of operational land monitoring that include land cover mapping. An operational system for land monitoring requires integrated use of observations, their efficient and continual transformation into useful, standardized and timely information, their assimilation into models and their application in assessments, policy and decision making. The current dominant paradigm of land cover mapping is based on qualitative classification systems that separate the space into entities to which classes are then assigned. The major problem of the traditional land cover mapping methodologies lies in the fact that the extracted information, being products of classification, are subject to conceptualization of both the producers and the users. However, they do not often match. Initiatives for harmonization and standardization of land cover mapping are attempts to reach a common conceptual platform. Nevertheless, these solutions cannot essentially overcome the problem. The premise of this research is that the solution could be found in quantitative land cover modeling. The objective of the research is concept, requirements and possibilities of quantitative cartographic land cover modeling under conditions of increased demand for appropriate, quality and up-to-date information on the environment and natural resources. Since the optical satellite sensors are the primary data source for generating the land cover information, the research was focused on quality of both the Earth observation data and the methods of quantitative parameters modeling that serve for the description of land features’ characteristics. The most often used spectral indices and biophysical parameters that are considered instruments for quantitative description of basic land cover categories (vegetation, water, land and artificial surfaces) are analyzed. Spectral indices are suitable for quantitative modeling because they are direct function of satellite data. However, as they do not represent absolute biophysical characteristics of features, their interpretation is often problematic, especially in the case of describing vegetation as the most complex category. On the other hand, modeling of biophysical parameters is a challenge. Simple empirical models of biophysical parameters’ estimation from spectral indices are connected with significant uncertainty which makes them inappropriate for operational use. Deterministic (physical) models of biophysical parameters’ estimation are good theoretical basis for the operational mapping, but knowledge of the uncertainty is necessary. Special attention was paid to experimental assessment of uncertainty of physically modeled biophysical parameters of vegetation in terms of various uncertainty sources. The concept of operational quantitative land cover monitoring is also analyzed from the aspect of spectral and spatial heterogeneity of the Earth observation data. A system of organizing data and information by use of multiscale hierarchical reference grid is introduced with the grid structure adjusted to the major operational optical multispectral satellite sensors. Such a system enables the optimal use of available data and the possibility to apply object oriented analysis..."

"Cilj ove doktorske disertacije je bio ispitivanje probiotskih osobina novih, autohtonih sojeva laktobacila izolovanih iz gastrointestinalnog trakta zdravih beba i uzoraka domaćeg kravljeg sira sa područja Gornjeg Milanovca. Ukupno je obrađeno 46 uzoraka (43 humanog i 3 poreklom iz sira) iz kojih su izolovana 143 bakterijska soja. Od ovog broja 120 izolata su bili Gram pozitivne koke, 15 izolata Gram pozitivni bacili i 8 izolata Gram negativni bacili. Pripadnost rodu Lactobacillus je potvrđena kod 8 izolata (7 humanog i 1 poreklom iz sira) za koje je pokazano da su katalaza negativni, nesporulativni Gram pozitivni bacili, sposobni da rastu na MRS podlozi u anaerobnim uslovima. Genotipska identifikacija je pokazala da izolati Lac1, Lac2, Lac6 i Lac7 pripadaju vrsti Lactobacillus plantarum, izolati Lac3 i 5s vrsti Lactobacillus casei, izolat Lac4 vrsti Lactobacillus paracasei i izolat Lac5 vrsti Lactobacillus gasseri. Iz daljih ispitivanja je isključen izolat Lac5 zbog slabog rasta na čvrstoj podlozi. Fiziološkom i biohemijskom karakterizacijom ispitivanih izolata pokazano je da se radi o nehemolitičnim, homofermentativnim vrstama koje rastu u širokom opsegu temperature (10-40ºC), koncentracije NaCl (2,0-6,5%) i pH vrednosti (2,0-8,0). Takođe, utvrđeno je da izolat 5s raste mnogo sporije u odnosu na ostale izolate. Izolati su pokazali visok stepen otpornosti na lizozim, kisele uslove sredine i prisustvo žučnih soli. Proteolitička aktivnost je detektovana samo kod izolata Lac1. Svi ispitivani izolati rastu u prisustvu fenola od 0,4%, a izolat Lac2 i pri koncentraciji od 1%. Ispitivanje osetljivosti na najčešće upotrebljavane antibiotike pokazalo je da su svi izolati rezistentni prema vankomicinu, amikacinu, gentamicinu i norflokscinu, a osetljivi prema ampicilinu i rifampicinu. Ni jedan od ispitivanih izolata nije pokazao osetljivost prema -amilazi, tripsinu, himotripsinu, pronazi E i katalazi. Ispitivanje osnovnih probiotskih osobina pokazalo je visok procenat (preko 79%) preživljavnja izolata u simuliranim uslovima gastrointestinalnog trakta. Osim toga, bezćelijski supernatanti svih izolata su pokazali antimikrobno dejstvo prema pojedinim Gram pozitivnim i Gram negativnim bakterijama, dok je ono izostalo prema kvascima i plesnima, kao i prema vrstama iz roda Lactobacillus..."

"The aim of this Doctoral thesis was to investigate the probiotic properties of new, indigenous lactobacilli strains isolated from the gastrointestinal tract of healthy babies and homemade cheese samples originating from the area of Gornji Milanovac. We collected 46 samples (43 of human and 3 of dairy origin), from which 143 bacterial strains were isolated. Among them, 120 isolates were identified as Gram positive cocci, 15 isolates as Gram positive bacilli and 8 isolates as Gram negative bacilli. We showed that 8 isolates (7 of human and 1 of dairy origin) were catalase-negative, Gram positive bacilli that do not form spores and are able to grow on MRS medium in anaerobic conditions, and confirmed that they belong to the genus Lactobacillus. Genotypic identification showed that isolates Lac1, Lac2, Lac6 and Lac7 belong to the species Lactobacillus plantarum, isolates Lac3 and 5s to the Lactobacillus casei, Lac 4 to the Lactobacillus paracasei and isolate Lac5 to the Lactobacillus gasseri. Isolate Lac5 was excluded from further studies due to its poor growth on agar medium. Physiological and biochemical characterization showed that all isolates were nonhemolytic, homofermentative species, growing in a wide range of temperature (10 to 40ºC), NaCl concentration (2.0 to 6.5%) and pH (2.0 to 8.0). Comparing to the other isolates, the 5s grew slower. The isolates showed high degree of resistance to lysozyme, acidic environmental conditions and the presence of bile salts. Only Lac1 isolate possessed proteolytic activity. All isolates grew in the presence of 0.4% phenol and Lac2 even at its concentration of 1%. Investigation of isolates sensitivity to antibiotics showed that all isolates were resistant to vancomycin, amikacin, gentamicin and norfloxacin, but sensitive to ampicillin and rifampicin. All tested isolates showed no sensitivity to α-amylase, trypsin, chymotrypsin, pronase E and catalase. Investigation of probiotic properties showed that isolated strains survived in high percentage (over 79%) in simulated conditions of gastrointestinal tract. Additionally, all isolates showed antimicrobial effect against certain Gram positive and Gram negative bacteria, but not against yeasts and molds. No antimicrobial effect was detected against other species of the Lactobacillus genus. This last feature is important because it gives the possibility of combining two or more species in the potential probiotic product..."

"Регија Бирач представља сложену цјелину која се одликује различитим природним закономјерностима и антропогеним утицајима. Бирач чини административно уоквирени простор седам општина у просторном систему потенцијалних и дијелом активираних природних и антропогених туристичких вриједности. Кључна слабост развоја туризма у организационом смислу јесте недостатак одговарајуће институционалне инфраструктуре. Туристичке организације републике, регије и општина, треба да стварају системска оперативна рјешења за реализацију потенцијалних могућности у регионалном, међурегионалном и ширем простору. Материјалну базу као битан елеменат туристичког развоја треба унапређивати побољшањем квалитета туристичко-угоститељских капацитета кроз плански концепт обнове и осавремењивања смjештајних капацитета и изградње нових који могу задовољити потребе и захтјеве туристичке потражње. Општинама Бирча недостаје инвентаризација и категоризација приватног смјештаја, гдје би се на бази збирних података могла направити квалитетна понуда смјештаја у кућној радиности. Развој туризма подразумијева усаглашавање одрживог модела економског развоја, усаглашен развој са осталим корисницима простора на основу планске просторне организације и уважавање еколошких стандарда. Транзитни туризам је посебан вид туризма којем се у Бирчу треба посветити већа пажња због све веће мобилности туриста да се удобније и брже крећу, потребно је удовољити њиховим захтјевима и на путу до крајњег одредишта. Туристичка пропаганда и други видови медијског представљања су битан сегмент укупног туристичког развоја и комуникације са становништвом и потенцијалним туристима. Израдњом јединствене туристичке карте за регију Бирач и осталим пропагандним материјалом обогатило би се презентовање овог простора. Значајна је и улога медија која се односи на развијање еколошке културе и односа становништва према културном насљеђу. Поштујући савремене еколошке стандарде створени су услови да се у складу са локалним еколошким плановима може рачунати на битне перспективе за развој еко-туризма који своју афирмацију стиче као комплементарни сегмент са другим гранама, а посебно са етно-туризмом. Туризам као дјелатност у Бирчу треба посматрати као значајну привредну грану која са основама природних и антропогених вриједности овај геопростор издваја ван локалних и регионалних оквира са тенденцијом постепеног примања одлика туристичке регије..."

"Summary The region of Birac is a complex unity which is specific for its different natural regularities and anthropogenic influences. Birac is consistent of seven administratively connected municipalities within territorial system of potential and partly activated natural and anthropogenic tourist assets. The key of underdeveloped tourism, concerning organization, lies in the lack of suitable institutional infrastructure. The republic, regional and municipality tourist organizations need to provide a systematic and workable solution to realization of potential possibilities in regional, interregional and wider area. The material base, as important element of tourist development, needs to be improved by making better tourist offer using planed concept of renovation and improvement of accommodation capacities as well as building new ones which can satisfy all the needs of tourist requirements. Every municipality lacks inventory and categorization of private accommodation, where, using the base of summarized data, we could provide a highquality accommodation offer in the households. The development of tourism implies adjustment of sustainable model of economic development, coordinated development with the inhabitants of the area based on a planed organization of the space usage in compliance with ecological standards. Transit Tourism is a special type of tourism to whom in the Birac region should be granted more attention because of the growing mobility of tourists, in order to provide the tourists with better and more comfortable accommodation on their way to their destinations. Tourist propaganda as well as other means of media attention is a very important part of overall tourist development and communication with the citizens and potential tourists. Making the unique tourist map for the Birac region as well as using other propaganda material would improve presentation of this area. The role of the media is also important for developing ecological culture and public's atitude toward cultural heritage. Based on the local ecological planes, by complying the modern ecological standards the conditions that we can rely on important perspectives for development of eco-tourism, that gets its affirmation as a complementary part along with the other branches, and especially ethic-tourism, are made. Tourism in Birac region should be treated as an important part of economy, which with its natural and anthropogenic assets puts this geographical area out of its local and regional frames, providing the tendency for gradual development of it into tourist region..."

"Основни циљ истраживања у оквиру ове дисертације је постављање научно релевантних, теоријско исправних и апликативно прихватљивих основа вредновања физичкогеографских фактора водног биланса у функцији одрживог коришћења водних ресурса у сливу Тимока. Задаци истраживања се, пре свега, односе на изналажење најрелевантнијих узрочно-последичних веза и односа фактора природне средине и водних ресурса, као и водних ресурса и њиховог одрживог коришћења. Познавање елемената речних режима и биланса представља неопходан предуслов оптималног коришћења површинских вода. С обзиром на сложеност и обим предмета истраживања, у раду је постојала потреба за применом одговарајућих метода погодних за постављање полазних хипотеза, доказивање ставова, проверавање и обликовање научних закључака до којих се у раду желело доћи. У раду се тежило својеврсном доприносу методологији и унапређењу логичко-сазнајног поступка при чему су објективност, прецизност и практична примењивост добијених резултата били у фокусу. Допринос је дат описивањем, систематизацијом, објашњењима и новим подацима, као и чињеницом да се водни биланс и одрживо коришћење водних ресурса посматрају у просторном контексту и у узрочно-последичном односу међузависности. Водни режим је анализиран на основу података измерених на 10 хидролошких станица у сливу. Анализа средњемесечних и годишњих водостаја река у сливу је показала да је континуалност кретања водостаја током године условљена заједничким дејством плувијалног и нивалног чиниоца. Тимок припада рекама са плувио-нивалним режимом умерено- континенталне варијанте. Режим протицаја Тимока је у директној зависности од режима протицаја његових саставница, Белог и Црног Тимока. Амплитуда протицаја показује да је максимални средњемесечни протицај 12,1 пута већи од минималног средњемесечног протицаја, што указује на неуједначен режим протицаја..."

"The main purpose of the body of research presented in this thesis is to establish scientifically relevant, theoretically correct and applicatively acceptable bases for the evaluation of physical geographic factors of the water balance with the aim of achieving a sustainable use of water resources in the Timok River Basin. The tasks of the study are primarily related to identifying the most relevant causal connections and relations between environmental factors and water resources, as well as those between water resources and their sustainable use. The knowledge of the elements of river regimes and balances is a necessary precondition for an optimal use of surface waters. Having in mind the complexity and the scope of the subject of research, it was necessary to apply appropriate methods in order to define the initial hypotheses, prove the postulates, test and shape scientific conclusions towards which this study has led us. This thesis seeks to contribute to the methodology and improve the logical cognitive procedure, while laying focus on objectivity, accuracy and practical applicability of the results. The contribution consists in descriptions, systematization, explanations and new data, as well as the fact that the water balance and sustainable use of water resources are analyzed in a spatial context, taking into account the causal relationship between interdependent variables. The water regime is analyzed on the basis of data measured at ten hydrological stations in the basin. The analysis of average monthly and annual water levels in the river basin has shown that continuous water level fluctuations during the year are a result of a joint effect of pluvial and nival factors. The Timok belongs to rivers with a moderately continental pluvio-nival regime. Its flow regime directly depends on the flow regimes of its constituent tributaries, the Beli Timok and the Crni Timok. The amplitude of the flow shows that the maximum average monthly flow is 12.1 times higher than the minimum average monthly flow, indicating an uneven flow regim..."

"Gojaznost je oboljenje povezano sa nizom patoloških stanja kao što su: rezistencija na insulin (IR), kardiovaskularne bolesti (KVB) i Diabetes Mellitus tipa 2 (DMT2). Povećana ekspresija i aktivnost inducibilne azot-monoksid-sintaze (iNOS; engl. Inducible Nitric Oxide Synthase) u srcu u stanju gojaznosti, moţe dovesti do apoptoze kardiomiocita i hipertrofije srca, dok sa druge strane gojaznost zdruţena sa IR doprinosi smanjenoj aktivnosti Na+/K+-ATPaze, što dovodi do smanjenja kontraktilnosti vaskulature i razvoja sistemske hipertenzije. Endogeni estradiol svojim delovanjem sprečava nastanak IR i hiperglikemije i ostvaruje pozitivne efekte na kardiovaskularni sistem (KVS), ali sinteza i kardioprotektivni uticaj estradiola mogu biti smanjeni usled razvoja gojaznosti. Estradiol ostvaruje kardioprotektivne tako što utiče na smanjenje ekspresije i aktivnosti iNOS, kao i povećanje ekspresije i aktivnosti Na+/K+-ATPaze, posredstvom različitih signalnih molekula i kinaza, kao što su: supstrat receptora za insulin 1 (IRS-1; engl. Insulin Receptor Substrate)/ fosfatidil-inozitol-3-kinaza (PI3K; engl. Phosphatidylinositide 3-Kinase)/ protein kinaza B (Akt; engl. Protein Kinase B), ekstracelularnim signalima regulisane kinaze 1 i 2 (ERK1/2; engl. Extracellular Signal-Regulated Protein Kinases 1 i 2) kao i RhoA (engl. Ras homolog gene family, member A)/ROCK (engl. Rho-associated protein kinase). Pored direktnog efekta na srce, estradiol posredno reguliše i njegovu funkciju tako sto utiče na metabolizam i transport glukoze i SMK, preko transportera glukoze (GLUT; engl. Glucose Transporters) i translokaze masnih kiselina (FAT; CD36 ; engl. Fatty Acid Translocase). Za izradu ove doktorske disertacije je korišćeno 16 adultnih ţenki pacova soja Wistar, podeljenih u dve eksperimentalne grupe. Prva grupa pacova je tokom 10 nedelja hranjena standardnom laboratorijskom hranom za pacove, dok je druga grupa pacova tokom 10 nedelja hranjena standardnom laboratorijskom hranom obogaćenom sa 42% masti (HF reţim ishrane). Nakon 10 nedelja pacovi su ţrtvovani, sakupljena je krv i izolovan je serum, a srca su ekstrahovana i delovi tkiva su korišćeni za izolovanje proteina i RNK. U serumu pacova je odreĎivana koncentracija estradiola, dok su u lizatu srca pacova odreĎivane koncentracije L-Arginina (L-Arg), NO i slobodnih masnih kiselina (SMK). Metodom qRT-PCR odreĎivan je nivo iRNK iNOS u srcu pacova..."

"Obesity is associated with several pathological conditions such as: insulin resistance (IR), cardiovascular disease (CVD) and Diabetes Mellitus type 2 (DMT2). Obesity related inducible nitric oxide synthase (iNOS) overexpression could lead to cardiac hypertrophy, while on the other hand obesity induced IR contributes to the reduced Na+/K+-ATPase activity, leading to vascular contractility impairment and development of systemic hypertension. Endogenous estradiol prevents IR and hyperglycaemia and has protective effects on the cardiovascular system (CVS), but the synthesis and cardioprotective effect of estradiol can be reduced due to the development of obesity. Estradiol exerts cardioprotective effects by reducing the expression and activity of iNOS, as well as by increasing the expression of Na+/K+-ATPase activity by regulating the activity of signaling molecules and kinases, such as: insulin receptor substrate 1 (IRS-1)/phosphatidylinositol-3-kinase (PI3K)/protein kinase B (Akt, PKB), extracellular signal regulated kinase 1 and 2 (ERK1/2) as well as RhoA (Ras homolog gene family, member A)/ROCK (Rho-associated protein kinase). Additionally, estradiol indirectly regulates CVS function by influencing the metabolism and transport of glucose and free fatty acids (FFA), through glucose transporter (GLUT) and FAT; CD36 (Fatty Acid Translocase). In this doctoral dissertation 16 adult female Wistar rats were used and divided into two experimental groups. The first group of rats was fed a standard chow for laboratory rats for 10 weeks, while the second group of rats was fed a standard chow for laboratory rats enriched with 42% fat (HF diet) for 10 weeks. After 10 weeks, the rats were sacrificed, blood was collected and the serum isolated, the hearts were collected, and its tissue fragments were used to isolate proteins and RNA. The concentration of estradiol was measured in serum, while concentrations of L-Arginine (L-Arg), NO and free fatty acids (FFA) were measured in the heart lysates. qRT-PCR method was used to measure the level of iNOS mRNA in rats’ hearts. Na+/K+-ATPase was measured in plasma membranes of rats’ hearts. Western blot was used to measure the level of the following proteins: iNOS, NFkB-p50, ERα, p85 and p110 subunits of PI3K, NDRG2, RhoA, ROCK1 and ROCK2 in heart lysates. The level of phosphorylation and expression of Akt and ERK1/2 kinases, as well as the IRS-1/PI3K associations, were determined in heart lysates..."

"Proučavanjem zajednica akvatičnih makrobeskičmenjaka tekućih voda na području Beograda u periodu 2007-2011. godina zabeleženo je 115 taksona iz 48 porodica, 8 klasa i 5 razdela. Istraživani vodotoci nalaze se pod velikim antropogenim stresom i prema važećem Pravilniku o parametrima ekološkog i hemijskog statusa površinskih voda i parametrima hemijskog i kvantitativnog statusa podzemnih voda (Službeni glasnik RS 74/2011), svrstani su u tri tipa i to: tip 1, vrlo velike ravničarske reke sa dominacijom finog nanosa – Dunav i Sava; tip 2, velike reke sa dominacijom srednje krupnog nanosa – Kolubara; i tip 3, male i srednje velike reke nadmorske visine do 500 m sa dominacijom krupnog nanosa – Topčiderska i Železnička reka. Istraživanja su vršena od 2007. do 2011. godine u periodu visokih voda (maj/jun) i niskih voda (septembar/oktobar). Takođe je korišćen i materijal prikupljen u periodu od 1996. do 2000. godine od strane istaživača laboratorije Odeljenja za hidroekologiju i zaštitu voda Instituta za biološka istraživanja \"Siniša Stanković\" Univerziteta u Beogradu. U tipu 1 vodotoka na području Beograda zabeležena su 63 taksona u Dunavu i 43 u Savi, sa dominacijom oligoheta. Najveći broj taksona zabeležen je u tipu 2 vodotoka, 78 taksona u Kolubari, sa dominacijom insekatske komponente u zajednici. U tipu 3 vodotoka, u Topčiderskoj i Železničkoj reci, zabeleženo je 25, odnosno 36 taksona, pri čemu je u Topčiderskoj reci dominirala grupa oligoheta, dok su u Železničkoj reci najveći udeo u zajednici imale hironomide. Poređenjem sa rezultatima prethodnih istraživanja, analizirane su promene u sastavu i strukturi zajednica u istraživanim tokovima. Rezultati multivarijantne analize ukazuju da je karakterističnoj distribuciji vrsta u sva tri tipa istraživanih vodotoka u najvećoj meri doprineo hemijski sastav sedimenta. Fizički i hemijski parametri vode su takođe, u velikoj meri, pokazali uticaj na zajednice akvatičnih beskičmenjaka. Uočeno je da je u velikim rekama efikasnije razmatrati vezu zajednice akvatičnih beskičmenjaka i višemesečne prosečne vrednosti fizičkih i hemijskih parametara vode, dok su u manjim vodotocima bujičnog karaktera trenutno izmerene vrednosti pokazale veći uticaj na zajednice akvatičnih beskičmenjaka..."

"During the survey of the communities of aquatic macroinvertebrates of rivers and streams in Belgrade region 115 taxa from 48 families, 8 classes and 5 phyla were detected. These waterbodies are under a high anthropogenic stress and, based on the Regulation on the parameters of the ecological and chemical status of surface waters and the parameters of the chemical and quantitative status of groundwater (Official Gazette of RS 74/2011), they are classified into three types: Type 1, large lowland rivers with the domination of fine bottom sediments – the Danube and the Sava River; Type 2, large rivers with the domination of medium sized sediments – the Kolubara River; and Type 3, small to medium sized rivers at elevation of up to 500 m, with the domination of the hard bottom substrate – the Topčiderska River and the Železnička River. The research was carried out from 2007 to 2011, in the period of high water levels (May/June) and of low water levels (September/October). Additional material, collected from 1996 to 2000 by researchers from the laboratory of the Department of Aquatic Ecology of the Institute for Biological Research \"Siniša Stanković\" of the University of Belgrade, was also included in the analyses. In the Type 1 watercourses in Belgrade region, 63 taxa were recorded in the Danube and 43 in the Sava River, with Oligochaeta as the dominant group. The largest number of taxa were identified in the Type 2 watercourses, 78 taxa in the Kolubara River, with the dominance of the insect component of the community. In the Type 3 watercourses, in the Topčiderska River and the Železnička River, 25 and 36 taxa were recorded, respectively. While Oligochaeta prevailed in the Topčiderska River, Chironomidae were the dominant group in the Železnička River. Changes in the composition and structure of communities in the studied streams were observed following the comparison with the previous findings. The results of a multivariate analysis indicate that the chemical composition of the sediment largely contributed to the characteristic distribution of species in all three investigated watercourses. Physical and chemical parameters of water also showed a significant impact on communities of aquatic invertebrates. Our results suggest that it is more effective to analyse the relation of the average values of chemical parameters across several months and macroinvertebrate assemblages in the case of large rivers, while for smaller size watercourses of torrential character, the current values of chemical parameters were better correlated with these communities and had a greater impact on them..."

"Holarktička porodica Anthroleucosomatidae jedna je od najheterogenijih i najproblematičnih porodica u okviru klase Diplopoda. U mnogim radovima je označavana kao „noćna mora“ i u mnogim slučajevima je služila kao „korpa za otpatke“ za taksone hordeumatida koji nisu mogli biti uvršteni u neke bolje definisane porodice. Stoga je ova disertacija fokusirana na rešavanju kompleksnih sistematskih, filogenetskih, biogeografskih i razvojnih odnosa među predstavnicima porodice Anthroleucosomatidae. Kako se radi o porodici sa mnogobrojnim premeštanjima taksona unutar i izvan nje, u uvodnom delu teze dat je kompletan, hronološki i taksativan istorijat proučavanja taksonomije i sistematike porodice Anthroleucosomatidae. Navedeni su svi taksoni koji su počev od 1876. pa zaključno sa 2016. godinom svrstavani u navedenu porodicu. U prvom delu ove doktorske disertacije, na osnovu čitavog niza relevantnih uporednomorfoloških karaktera, kao i biogeografskih osobenosti, izvršen je rearanžman 35 rodova antroleukozomatida, sa ukupno 84 vrste, u 12 kompleksa rodova — Alloiopus, Anamastigona, Anthroleucosoma, Bulgarosoma, Caucaseuma, Dentatosoma, Enghoffiella, Flagellophorella, Herculina, Leschius, Ratcheuma i Vegrandosoma. Polovina ovih kompleksa uključuje samo po jedan rod, dok su tri monotipska. Za svaki kompleks je dat kratak opis njegovih pripadnika sa opisima najbitnijih uporedno-morfoloških karaktera, a pre svega strukture anteriornih i posteriornih gonopoda, kao i pregonopodalnih nogu kod mužjaka. U okviru nekih kompleksa izvršena je podela na nekoliko grupa vrsta. Ovi kompleksi predstavljaju osnovu za uspostavljanje suprageneričkih kategorija. Rodovi Bulgardicus, Camptogona i Ghilarovia su isključeni iz porodice Anthroleucosomatidae. Za određivanje filogenetskih odnosa između kompleksa rodova i unutar njih uključen je veći broj karaktera mužjaka, pre svega struktura njihovih gonopoda koja ima najveći informacioni značaj u filogenetskim razmatranjima. Dobro razvijeni telopoditi na gonopodama mužjaka smatraju se pleziomorfnim stanjem karaktera kod Diplopoda, pa je na osnovu njihovog prisustva ili odsustva, kao i strukture utvrđeno da postoji više filetičkih linija antroleukozomatida, čak i u okviru određenih kompleksa rodova..."

"U radu se analizira dinamičko ponašanje noseće konstrukcije portalne dizalice usled dejstva kolica kao pokretnog opterećenja. Dat je prikaz klasifikacije portalnih dizalica pri čemu su izdvojene portalne dizalice za kontejnerske terminale sa svojim visokih performansama koje imaju stalnu tendenciju poboljšanja. Prvo je dat koncept primene analitičkog pristupa za modeliranje noseće konstrukcije preko sistema elastičnih tela tipa prizmatične grede i razmatranje slobodnih poprečnih oscilacija. Kao savremen i pre svega neophodan, usvojen je kombinovani pristup za istraživanje naslovnog problema, tj. konačnoelementni pristup je iskorišćen za modeliranje noseće konstrukcije portalne dizalice a principi analitičke mehanike su iskorišćeni za modeliranje kolica. Razmatraju se dva najčešća konstrukciona tipa portalne dizalice za formiranje modela strukture. Kolica su obuhvaćena kroz model pokretne mase, model pokretnog oscilatora i kroz model pokretnog oscilatora sa klatnom koji predstavlja originalan model pokretnog opterećenja. Za svaki od modela je utvrđena dinamička interakcija između ovih sistema i postavljeni su matematički modeli koji predstavljaju sistem diferencijalnih jednačina drugog reda sa promenljivim koeficijentima. Rešenja su dobijena pomoću originalnih programa, na bazi metode direktne integracije‐ Njumarkove metode. Identifikacija i analize odziva su izvršene za dva realna primera portalnih dizalica. Istražen je uticaj brzine, ubrzanja/usporenja i težine kolica, kao i uticaj klaćenja tereta i elastične opruge u sistemu kolica. Dobijeni rezultati se mogu iskoristiti u početnim fazama konstruisanja portalnih dizalica koje imaju tendenciju da ostvare veoma visoke performanse, u smislu ostvarivanja boljeg uvida u dinamičko ponašanje."

"The dynamics of a two‐dimensional gantry crane structure subjected to various types of moving load is examined in this work. First, the classification of gantry cranes is suggested and group of gantry cranes at container terminals are distinguished because of high performances which have tendency to become even better in near future. The analytical approach is introduced in modeling the gantry structure as continuous system with transverse vibrations. However, modern approach, i.e. combined finite element and analytical method is adopted to solve the title problem. Two types of structure of gantry cranes are considered. Three types of trolleys are implemented in calculation, i.e. moving mass, moving oscillator and moving oscillator with swinging payload as original model are considered as moving loads acting upon the structure of the gantry cranes. The interaction between the structure and each moving load model is derived and the governing equations for MDOF systems are obtained. The postulated equations, which are second order differential equations with time dependent coefficients, are solved with direct integration method‐Newmark method. The analysis is applied to two types of gantry cranes and dynamic responses are obtained for both the structure and the trolley. There are studied factors of moving loads such as magnitude, speed, acceleration, deceleration and factors within the trolley structure such as swinging of the payload and spring stiffness. Numerical results reveal that used approach is useful and can draw conclusions for structural design purposes of gantry cranes."

"Nedostatak gvožđa (Fe) predstavlja jedan od glavnih ograničavajućih faktora u proizvodnji useva širom sveta, koji značajno umanjuje prinos i kvalitet. Sa druge strane, koristan efekat silicijuma (Si) na rastenje i razviće biljaka, posebno u uslovima stresa, dobro je poznat u literaturi. Cilj ove teze je bio da se prouči mehanizam kako Si ublažava stres izazvan nedostatkom Fe kod dikotiledonih biljaka (strategija I usvajanja Fe), o kome se do sada ništa nije znalo. Kao model biljka odabran je krastavac (Cucumis sativus L.) kao vrsta koja akumulira Si. Izvršena su detaljna izučavanja mobilnosti Fe u apoplastu, biosinteze jedinjenja koja mobilišu Fe i njegovog daljeg usvajanja na bazi redukcije u korenu, zajedno sa ekspresijom gena uključenih u te procese. U nadzemnom delu biljke, proučavana je remobilizacija Fe iz starijih u mlađe listove, tako što su paralelno mereni distribucija 59Fe u listovima na različitim pozicijama i koncentracija helatora nikocijanamina (NA), zajedno sa ekspresijom gena za nikocijanamin sintazu (NAS) uključenu u njegovu biosintezu i YSL (eng. yellow stripe-like) transporter koji posreduju u transportu Fe-NA floemom. Ishrana Si uticala je na povećanu akumulaciju Fe u apoplastu i Fe-mobilizirajućih jedinjenja u korenu, kao i na stimulaciju mašinerije za usvajanje Fe. U listovima, Si je uticao na relativnu distribuciju Fe povećavajući remobilizaciju Fe iz starijih listova zbog povećane akumulacije NA i ekspresije YSL1, što je pospešilo heliranje Fe i njegovu retranslokaciju u mlađe listove. Ova teza pruža, po prvi put, objašnjenje mehanizma koji Si ispoljava u prevazilaženju nedostatka Fe, a koji se sastoji u povećanju rezervi Fe u apoplastu korena, njegove mobilizacije i trasporta iz korenu u izdanak, kao i poboljšane remobilizacije iz starijih u mlađe listove."

"Iron (Fe) deficiency represents a major limiting factor for crop production worldwide, affecting both crop yield and quality. Beneficial effect of silicon (Si) on plant growth and development, especially under stress conditions, is well documented in the literature. The objective of this thesis was to investigate the mechanisms of how Si ameliorates Fe deficiency in Strategy I plants, which has not been understood until recently. Cucumber (Cucumis sativus L.) was selected as a common model plant for Fe research and which is also known as a Si-accumulating dicot. Detailed analyzes of the dynamics of apoplastic Fe, biosynthesis of Fe-mobilizing compounds and reduction-based Fe acquisition were performed in roots along with the expression of relevant genes involved in these processes. At the shoot level, distribution of 59Fe was measured in the in leaves at different positions and developmental stages in parallel with the concentration of the Fe chelator nicotianamine (NA) and the gene expression of nicotianamine synthase (NAS) involved in its biosynthesis. The expression of yellow stripe-like (YSL) transporters mediating pholem transport of Fe-NA in shoot was also determined. Silicon nutrition increased the accumulation of apoplastic Fe and Fe mobilizing compounds in roots. In leaves, Si affected relative Fe distribution by enhancing Fe remobilization from old leaves via increased NA accumulation and expression of the YSL1, which stimulated Fe chelation and its retranslocation to younger leaves. This thesis for the first time elucidates the mechanism of Si-mediated alleviation of Fe deficiency stress, by increasing the root apoplastic Fe pool, enhancing its acquisition by roots and translocation to shoots and also remobilization of Fe from older to younger leaves."

"Gladovanje predstavlja stanje tokom kojeg nema unosa hrane, pa se stoga potrebe za energijom zadovoljavaju razgradnjom endogenih energetskih depoa. U zavisnosti od dužine trajanja gladovanje može narušiti energetsku homeostazu. Hipotalamus kao mesto integracije signala o energetskom statusu organizma ima veoma važnu ulogu u regulaciji energetske homeostaze. Prethodne studije su pokazale da tokom kratkotrajnog gladovanja dolazi do smanjenja koncentracije insulina u krvi, dok je u hipotalamusu detektovana povećana količina insulina. Ovo neočekivano saznanje otvorilo je mnogobrojna pitanja, stoga je predmet ove doktorske disertacije bio ispitivanje uticaja šestočasovnog gladovanja na ekspresiju insulina u hipotalamusu i ispitivanje adaptivnog značaja ovog fenomena. U ekperimentima su korišćeni mužjaci pacova Wistar soja. Jedna grupa životinja imala je neometan pristup hrani (ad libitum), a drugoj je hrana uklonjena u trajanju od šest sati. Analizirana je genska i proteinska ekspresija insulina u hipotalamusu. Pokazano je da nakon šest sati gladovanja dolazi do povećanja količine insulina, kao i povećanja ekspresije iRNK za insulin. Proinsulin i insulin su detektovani u neuronima periventrikularnog jedra hipotalamusa i u ependimskim ćelijama koje okružuju treću moždanu komoru. Koncentracija glukoze i insulina u krvi bila je smanjena nakon kratkotrajnog gladovanja dok je u cerebrospinalnoj tečnosti ostala nepromenjena. Nakon kratkotrajnog gladovanja zabeležena je povećana količina aktivnog insulinskog receptora u periventrikularnom jedru. Pored toga, u membranskoj frakciji proteina izolovanih iz hipotalamusa zabeleženo je povećano prisustvo GLUT1 (55kDa), izoforme karakteristične za endotelne ćelije, povećanje neuronskih GLUT2 i GLUT3, dok je količina astrocitne GLUT1 (45 kDa) izoforme i GLUT4 ostala nepromenjena. Nakon šestočasovnog gladovanja nije zabeležena koekspresija aktivnog insulinskog receptora i glukoznih transportera. Količina glikogena u hipotalamusu ostala je nepromenjena..."

"Multipla skleroza (MS) je hronična, inflamatorna, demijelinizirajuća i degenerativna bolest centralnog nervnog sistema (CNS), koja se najčešće javlja kod mlañih osoba. Smatra se da imunski sistem ima ključnu ulogu u patogenezi MS, odnosno da bolest nastaje usled autoimunskog odgovora usmerenog prema proteinima mijelinskog omotača. MS je veoma raznolika bolest u svom kliničkom ispoljavanju, što je najverovatnije posledica različitih molekulskih mehanizama koji su uključeni u njenu patogenezu. Usled destrukcije mijelinskog omotača i degeneracije aksona neurona, dolazi do deficita u motornim, senzornim i kognitivnim funkcijama obolelih, koji mogu biti prolaznog ili trajnog karaktera. Trenutnim terapijskim pristupima može se uticati na odlaganje pojave novih neuroloških ispada i može se usporiti hronično pogoršavanje stanja kod pacijenata, ali se ne omogućava njihovo izlečenje. Eksperimentalni autoimunski encefalomijelitis (EAE) je najčešće korišćeni eksperimentalni model za proučavanje patofiziologije MS. Upotreba ovog modela, koji oponaša autoimunsku patogenezu MS, dovela je do mnogih saznanja o mehanizmima neuroimunoloških procesa, to jest, o prelasku imunskih ćelija iz krvotoka u CNS, o njihovoj interakciji sa lokalnim ćelijama glije i neuronima i o sledstvenoj inflamaciji, kao istaknutom aspektu MS. Hemokini su citokini koji imaju ključnu ulogu u regulaciji migracije imunskih ćelija na mesto inflamacije prilikom odbrane organizma od patogena ili tokom patoloških imunskih procesa, poput MS. Hemokini najčešće stimulišu imunski odgovor privlačenjem ćelija imunskog sistema na efektorska mesta, meñutim neki od njh ispoljavaju i regulatorne ili antiinflamatorne uloge, poput CXCL12. CXCL12 deluje antiinflamatorno sprečavanjem prelaska autoreaktivnih imunskih ćelija iz perivaskularnog prostora u parenhim CNS-a, izazivanjem apoptoze autoreaktivnih T ćelija i stimulisanjem promene proinflamatornog karaktera ovih ćelija u antiinflamatorni..."

"Multiple sclerosis (MS) is a chronic, inflammatory, demyelinating and degenerative disease of the central nervous system (CNS) that occurs preferentially in young adults. Immune system plays a key role in its pathogenesis. It is considered that MS develops due to an autoimmune response directed against myelin sheet components. MS is a very heterogeneous disease in its clinical manifestations, which is most probably a consequence of diverse molecular mechanisms involved in its pathogenesis. As a consequence of myelin sheet destruction and axonal degeneration, transient or permanent deficits in motor, sensory and cognitive functions appear in MS patients. Therapies which are currently in use decrease the frequency and the severity of acute attacks and slow down the rate of neurological deterioration, but do not cure the patients. Experimental autoimmune encephalomyelitis (EAE) is the most widely used experimental model for studying pathophysiology of MS. The use of this model, which mimics autoimmune pathogenesis of MS, led to many discoveries about neuroimmunological processes, such as egression of immune cells from the blood stream into the CNS, immune cell interaction with resident glial cells and neurons and subsequent inflammation, as an important aspect of MS. Chemokines are cytokines with a central role in regulation of immune cell migration at the site of inflammation during pathogen invasion and during pathological immune processes, such as MS. Most often, chemokines boost immune response by attracting immune cells at the effector sites. However, some chemokines, including CXCL12, exert regulatory or antiinflammatory roles. CXCL12 prevents egress of autoreactive immune cells from the perivascular space into the CNS parenchyma, induces autoreactive T cell apoptosis and stimulates shifting of proinflammatory phenotype of these cells towards antiinflammatory phenotype..."

"Komasacija je danas veoma značajna i predstavlja provereni instrument za razvoj poljoprivrede i seoskih područja. Glavni cilj komasacije oduvek je bio ukrupnjavanje poljoprivrednih poseda u što manji broj bolje oblikovanih parcela, kako bi se poboljšala primarna poljoprivredna proizvodnja i unapredio njen razvoj. Naime, razvoj poljoprivrede je jedan od suštinskih faktora razvoja i unapređenja života na selu. U razvijenim zemljama se već dugo na selo ne gleda kao na poligon namenjen isključivo poljoprivrednoj proizvodnji. Zbog toga u zemljama Zapadne Evrope komasacija služi i kao sredstvo za sveobuhvatni razvoj sela. Novi koncept ruralnog razvoja tretira komasaciju kao složeni projekat koji, između ostalog, ima za cilj i trajnu obnovu i unapređenje seoske zajednice. Uspešno izvršena komasacija dovodi do opšteg unapređenja poljoprivrede, povećanja produktivnosti, efikasnosti i konkurentnosti kompletnog poljoprivrednog sektora. Ona takođe vodi i boljem planiranju i upravljanju zemljištem, otvara nova radna mesta u poljoprivrednim regionima, olakšava priliv privatnih i javnih investicija u ovoj oblasti, doprinosi unapređenju zaštite životne sredine i omogućava upravljanje prirodnim resursima na efikasan način. U mnogim državama Centralne i Istočne Evrope uslovi života na selu su se pogoršali tokom tranzicionog perioda. Velika nezaposlenost i loša infrastruktura dovele su do toga da su sela postala manje atraktivna mesta za život. Radi poboljšanja situacije realizovan je veliki broj pilot-projekata komasacije sa namerom da se zemljama u tranziciji omogući pokretanje komasacije u sopstvenim uslovima i unapredi poljoprivredna proizvodnja i kvalitet života na selu. Prevashodni cilj ovog rada je razvoj metodologije za ocenu zemljišnih komasacionih sistema koja bi na najoptimalniji način doprinela uspostavljanju efikasnog sistema komasacije u datim uslovima..."

"Land consolidation is still very important today and represents a proven instrument of development of agriculture and rural regions. The main objective of land consolidation has always been the consolidation (reallocation) of the agricultural holdings into the fewest number of better designed parcels, in order to improve the primary agricultural production and promote its development. Namely, the development of agriculture is one of the essential factors of development and improvement of rural living. In the developed countries for quite some time village has not been perceived as the training ground intended solely for agricultural production. For that reason in West European countries land consolidation also serves as the means for comprehensive rural development. The new rural development concept treats land consolidation as a complex project which, among other things, aims at continual renewal and promotion of the rural community. Successfully implemented land consolidation leads to overall upgrading of agriculture, increase in productivity, efficiency and competitiveness of the entire agricultural sector. It also leads to a better planning and land management, creates new jobs in agricultural regions, facilitating the flow of private and public investments into this field, contributes to promotion of the environment protection and enables efficient natural resources management. The primary objective of this research is development of methodology for valuation of land consolidation systems which would contribute in the most optimal way to establishing the efficient system of land consolidation in the circumstances. The first difficulty encountered in development of the methodology was the lack of a clear definition of land consolidation as a system. In Chapter 3 for the first time the optimal land consolidation system has been defined which best logically connects all the elements of the system. The optimal model also presents an example of a good model which was necessary to define in order to compare the concrete land consolidation systems..."

"aktivnost neurona ima veliki značaj jer je magnetno polje umerene jačine prisutno u životnoj sredini. Jednako važno je i proučavanje mehanizama delovanja umereno jakog statičkog magnetnog polja na biofizičke osobine membrane neurona usled sve veće terapijske primene ovog polja, s tim što odgovarajuća jačina polja i dužina izlaganja polju tek treba da budu precizno određene. Uporednim eksperimentima primenom tehnike intracelularne registracije utvrđeno je da kratkotrajno izlaganje (15 min) umereno jakom statičkom magnetnom polju jačine 2,7 mT i 10 mT dovodi do promena bioelektrične aktivnosti spontano aktivnog Br neurona, dok promene nisu uočene kod nemog N1 neurona. Magnetno polje od 2,7 mT povećalo je amplitudu i skratilo trajanje akcionog potencijala, dok je magnetno polje od 10 mT hiperpolarisalo membranu, povećalo amplitudu, smanjilo frekvenciju i trajanje akcionog potencijala Br neurona. Veličine promena ispitivanih parametara zavisile su od jačine magnetnog polja i uočavane su i tokom perioda od 20 min nakon prestanka izlaganja Br neurona polju od 2,7 mT i 10 mT. Kombinovanim eksperimentima, biohemijskim analizama i 31P NMR spektroskopijom na okoloždrelnom ganglijskom kompleksu kao i tehnikom intracelularne registracije na Br neuronu vinogradskog puža, pronađeno je da kratkotrajno izlaganje (15 min) statičkom magnetnom polju jačine 10 mT povećava aktivnost Na+/K+ pumpe. Povećana aktivnost Na+/K+ pumpe dovodi do povećanja potrošnje ATP-a, kao i povećanja pHi posredstvom povećanja aktivnosti Na+/H+ izmenjivača, pH regulatornog sistema čija je aktivnost zavisna od gradijenta Na+ jona koji stvara i održava Na+/K+ pumpa. Rezultati elektrofizioloških eksperimenata na Br neuronu u saglasnosti su sa rezultatima dobijenim na okoloždrelnom ganglijskom kompleksu..."

"It is important to investigate the effects of moderate intensity static magnetic field on the bioelectric activity of neurons, since this field is present in the environment. Equally important is to reveal the mechanism of action of moderate intensity static magnetic field on biophysical properties of neuronal membranes, as this field has been applied in disease treatment, whereby proper dosages of exposure still need to be determined. Comparative intracellular registration studies showed that short term exposure (15 min) to the moderate intensity static magnetic field of 2,7 mT and 10 mT strength changed bioelectric activity of the spontaneously active Br neuron, while bioelectric activity of silent N1 neuron remained unchanged. The 2,7 mT magnetic field increased amplitude and decreased duration of action potential, whereas the 10 mT magnetic field hyperpolarized membrane potential, increased amplitude, decreased firing frequency and duration of action potential of the Br neuron. The magnitude of change of measured bioelectric parameters depended on the strength of applied magnetic field, and was still observed during the period of 20 min after exposure of Br neuron to the 2,7 mT and 10 mT magnetic field. Combined experiments, using biochemical analysis and NMR spectroscopy on whole snail brains and intracellular registration on Br neuron, showed that short-term exposure (15 min) to the 10 mT magnetic field increased activity of Na+/K+ pump. Increased Na+/K+ pump activity in the snail brain caused an increase in ATP consumption and increase in the pHi which is mediated through an increase in the activity of Na+/H+ exchanger, a pH regulatory system governed by the gradient of Na+ ions created and maintained by Na+/K+ pump. Electrophysiology from Br neuron is in agreement with the results obtained on the whole snail brain..."

"Progresija malignih tumora štitaste žlezde od dobro diferenciranih (papilarni karcinom) u nediferencirane, agresivne forme (anaplastični karcinom) praćena je različitim promenama na molekularnom nivou, koje omogućavaju malignoj ćeliji kontinuiranu aberantnu stimulaciju rasta i izbegavanje apoptotske smrti, što uz neoangiogenezu (formiranje novih krvnih i limfnih sudova) predstavlja preduslove tumorskog rasta i širenja. Predmet ovog rada je izučavanje molekularnih promena koje prate dediferencijaciju papilarnog u anaplastični karcinom štitaste žlezde, tj. ispitivanje promena ekspresionih profila apoptotskih molekula (Bcl-2, Bax, survivin) i limfangiogenog faktora (VEGF-C) u korelaciji sa kliničkim parametrima tokom progresije maligniteta tumora štitaste žlezde. Imunohistohemijskom analizom ekspresionih profila članova Bcl-2 familije konstatovano je da tokom progresije dolazi do smanjenja ekspresije Bcl-2 (antiapoptotski molekul), ali da je in situ apoptotska smrt detektovana TUNEL metodom na niskom nivou, uprkos visokih ekspresionih nivoa Bax (pro-apoptotskog) molekula. U isto vreme sa smanjenjem ekspresije Bcl-2 tokom progresije maligniteta dolazi do postepenog povećanja drugog antiapoptotskog molekula, survivina, koji je operativan nizvodno od Bax-a. Visoka ekspresija survivina je bila u korelaciji sa sniženim stepenom in situ detektovane apoptotske smrti, što sugeriše da survivin, a ne odnos Bcl-2/Bax ima ulogu u inhibiciji finalizacije programirane ćelijske smrti. Poređenjem imunohistohemijske ekspresije survivina sa kliničko-patološkim parametrima pacijenata utvrđena je značajna korelacija između visoke ekspresije survivina i prisustva metastaza u limfnim čvorovima. Ekspresioni profili VEGF-C proteina (angiogeni faktor koji promoviše formiranje tumorske vaskulature, a time i rast i širenje tumora) pokazali su porast tokom tumorske progresije i značajnu korelaciju sa prisustvom limfnih metastaza, ekstratiroidnom invazijom i uznapredovalim stadijumom tumorske bolesti..."

"Progression of malignancy of thyroid gland tumors from well differentiated (papillary carcinoma) to undifferentiated, aggressive form (anaplastic carcinoma) is accompanied by molecular changes. These enable continuous stimulation of aberrant growth and escape from apoptotic death, together with neoangenesis (formation of new blood and lymphatic vessels) which are prerequisites for tumor growth and spread. The objective of this work was examination of some molecular changes accompaning dedifferentiation of papillary to anaplastic carcinoma of the thyroid gland, i.e. an investigation of alterations in expression profiles associated with apoptosis (Bcl-2, Bax, survivin) and lympfhangiogenic factor, VEGF-C, in correlation with clinicopathological parameters during the progression of malignancy of thyroid gland tumors. Immunohistochemical analysis of expression profiles of Bcl-2 family members revealed decrease of Bcl-2 expression (anti-apoptotic molecule) during this progression, but a low level of in situ apoptotic cell death detected by the TUNEL method, despite high levels of Bax (pro-apoptotic molecule). The decrease of Bcl-2 expression was followed by increase of another anti-apoptotic molecule, survivin, which acts downstream from Bax. High survivin expression was found to correlate with the lower rate of in situ apoptotic cell death, suggesting that survivin, but not the Bcl-2/Bax ratio, has a role in finalization of programmed cell death. By comparing survivin immunohistochemical expression with clinico-pathological parameters of patients we found a significant positive correlation between high survivin expression and the presence of lymph node metastases. Expression profiles of VEGF-C protein (an angiogenic factor which promotes the formation of tumor vasculature, and thereby tumor growth and spread) revealed increased levels during tumor progression and a significant correlation with the presence of lymph node metastases, extrathyroid invasion and advanced stages of disease. Significant correlation between the expressions of two molecules, survivin and VEGF-C, in tumors with the presence of lymph metastases and in their metastatic tissues, suggests their coordinated roles in the metastatic process..."

"U ovoj disertaciji analiziraju se različiti aspekti racionalnih cenovnih balona u tradicionalnim i bihevioralnim finansijama. Studije koje proučavaju cenovne balone u tradicionalnim finansijama su veoma retke, jer se smatra da je cena jednaka fundamentalnoj vrednosti. Kratkotrajna pogrešna određivanja cene sredstava se objašnjavaju konceptima tradicionalnih finansija, ostajući u domenu hipoteze o racionalnim očekivanjima i hipoteze o efikasnim tržištima. S druge strane, bihevioralne finansije uvode kognitivno-psihološke i sociološke koncepte kako bi objasnile uočene anomalije i tržišne zagonetke. Motivacija i inspiracija za istraživanja sprovedena u ovoj disertaciji је uočen obrazac koji je postojao kod većine cenovnih balona u istoriji: često im je prethodila ekspanzivna monetarna politika, kao i pojava novih tehnologija, koje su obećavale da će biti veoma profitabilne, ali su bile i veoma rizične. Da bi se proverile hipoteze postavljene u radu, sproveden je ekonomski eksperiment, sa dva tretmana: jedan simulira ekspanzivnu, a drugi restriktivnu monetarnu politiku. Eksperimentalna struktura je osmišljena tako da obezbeđuje visok nivo interne i eksterne validnosti eksperimenta. Pri analizi podataka su primenjene ekonometrijske procedure za proveru stacionarnosti vremenskih serija cena i dividendi po akciji, kao i procedure za proveru postojanja kointegracije između njih. Rezultati istraživanja pokazuju da su cenovni baloni najčešći u uslovima ekspanzivne monetarne politike, pri trgovanju akcijama koje potencijalno mogu doneti visok prinos. Na osnovu ovih rezultata može se zaključiti da je ekspanzivna monetarna politika jedan od uzroka nastanka racionalnih cenovnih balona. Pored toga, uočeno je i da su psihološke karakteristike učesnika u eksperimentu uticale na formiranje cenovnih balona. Migracija tražnje iz akcija koje donose stabilne prinose u akcije koje potencijalno mogu da donesu visoke prinose se nije pokazala kao značajan uzrok formiranja racionalnih cenovnih balona. Zaključeno je da se značajni viškovi prinosa ii javljaju nakon nastanka dividendnih šokova. Uočeno je statistički signifikantno smanjenje vrednosti transakcija u uslovima restriktivne monetarne politike, odakle sledi pouka kreatorima monetarne politike da monetarna politika ne sme biti previše restriktivna, da se ne bi gušio obim trgovanja na berzi i smanjivala njena likvidnost."

"Different aspects of rational price bubbles in traditional and behavioral finance are analysed in this dissertation. Studies about rational price bubbles in traditional finance are very rare, because it is assumed that price equals fundamental value. Short-term asset mispricing is explained by traditional finance concepts, thereby staying in the domain of rational expectation hypothesis and efficient market hypothesis. On the other side, behavioral finance introduces cognitive psychological and social concepts in order to explain observed anomalies and market puzzles. The researches carried out in this doctoral thesis are motivated and inspired by a conspicuous pattern that has emerged in most of the previous price bubbles during history: they were often preceded by the expansionary monetary policy, as well as the emergence of innovative technologies that promised to be very profitable, but were also very risky. In order to test the hypotheses stated in the thesis, the economic experiment is conducted. There are two treatments in the experiment: one simulates expansionary, and the second one contractionary monetary policy. The experiment is designed with the aim to ensure high level of its internal and external validity. Adequate econometric procedures are implemented during data analysis in order to test stationarity and cointegration between price and dividend per share time series. Research results point out that price bubbles are most often to form in the conditions of expansionary monetary policy in trading with stocks that potentially bear high return. On the basis of these results, it can be concluded that expansionary monetary policy is one of the causes of rational price bubbles. Additionally, it was noticed that psychological characteristics of experimental participants had an effect on price bubbles’ emergence. The migration of demand from stocks that bear stable returns to those that can potentially bear high returns was not identified as an important reason for rational price bubbles’ forming. It is concluded that there are significant excess returns after dividend shocks occurrence. Statistically significant iv decrease in the transaction value is noticed in the contractionary monetary policy treatments."

"Kontrolna regija mitohondrijske DNK pokazala se kao odličan filogeografski marker kad je kompleks potočne pastrmke (Salmo cf. trutta) u pitanju. Krajem 20. veka ustanovljeno je pet osnovnih filogeografskih linija (haplogrupa) potočne pastrmke: dunavska, atlanska, mediteranska, jadranska i marmoratus koje uglavnom korespondiraju sa odgovarajućim slivovima. Analizirane jedinke na području Srbije nosile su haplotipove dunavske, atlanske i jadranske haplogrupe. Najdominantniji haplotip u slivu Crnog Timoka i rekama desne obale Dunava u Đerdapskom regionu pripadao je dunavskoj liniji i opisan je pod imenom Da23c (ACCN KC630984). Obzirom da je ovaj haplotip zasada otkriven samo u ovoj oblasti i to sa velikom učestalošću smatra se autohtonim za ovu regiju. U okviru Đerdapskog regiona uočen je i haplotip Da1, ali samo u Rečkoj reci u njenom desnom delu iznad nepremostive prepreke, vodopada visine 10 m. Kao pleziomorfni u odnosu na haplotip Da23c i široko rasprostranjen na ovom delu Balkanskog poluostrva postoji velika verovatnoća da je i on autohton za ovo područje, međutim nije isključena ni mogućnost da je unesen poribljavanjem. U okviru sliva Crnog Timoka osim autohtonog haplotipa Da23c otkriven je i Da2, koji je najverovatnije alohton. U prilog tome govore činjenice o rasprostranjenju haplotipova na zapadnom Balkanu, kao i podaci o korišćenju jedinki ovog haplotipa za poribljavanje i gajenje u Austrougarskoj, a kasnije u celoj Evropi i Srbiji. Osim dunavske u okviru šireg područja Đerdapa otkriveno je i prisustvo atlanske linije u rekama Brnjica, Dobrinjska, Porečka i Vratna, a samo u poslednjoj jedinke atlanskog haplotipa koegzistiraju sa pastrmkama koje nose autohtoni haplotip, Da23c. Atlanski haplotip ne smatra se autohtonim za Balkansko poluostrvo, pa je najverovatnije u reku Vratnu dospeo poribljavanjem, a analize jedarnog gena, laktat dehidrogenaze, pokazale su da se ove jedinke međusobno ukrštaju. Programske analize podataka osam mikrosatelitskih lokusa ukazale su na postojanje pet izdvojenih populacija u regionu severoistočne Srbije: sliv Crnog Timoka, reka Kožica, reka Rečka, reke Vratna i Zamna zajedno i reke Mala Boljetinska i Zlatica zajedno, što ukazuje na verovatnu komunikaciju i protok gena između ovih populacija. Mere upravljanja ovim ribolovnim područjima isključuju poribljavanje, jer trenutno ne postoji veštački mrest gde se koristi genetički materijal autohton za ovu oblast..."

"Control Region of mitohondrial DNA is a good phylogeographic marker for brown trout species complex (Salmo cf. trutta). Five main brown trout phylogeographic lineages (haplogroups) that mostly correspond to the particular basins have been established at the end of 20th century: Danubian, Atlantic, Mediteranean, Adriatic and marmoratus. Individuals from Serbia held haplotypes of Danubian, Adriatic and Atlantic haplogroups. Prevailing haplotype in the River Crni Timok drainage area and in the right tributaries of the River Danube from Đerdap region is Da23c (ACCN KC630984) of Danubian haplogroup. This haplotype is considered indigenous there since it has been found only in this area and with a great frequency. Another haplotype also detected in the Đerdap region is Da1, but only in the River Rečka, in its right fork above the 10 m high waterfall, which is an impassable obstacle for upstream dispersal of brown trout from downstream section. Considering its plesiomorphic character compared to haplotype Da23c and its wide distribution in this part of Balkan Peninsula, there is a high probability that it is indigenous for this region, as well. However, the possibility that it has been imported by stocking activities cannot be excluded. In addition to the indigenous haplotype Da23c, the haplotype Da2 was also detected in the Crni Timok drainage area, probably as an allochthonous one. This was supported by haplotype distribution in Western Balkans, as well as by history of stocking and breeding with the Da2 haplotype in Austria-Hungary and later, both in middle and southeastern Europe, including Serbia. Individuals of the Atlantic haplogroup were detected in rivers Brnjica, Dobrinjska, Porečka and Vratna of the broader Đerdap area. Only in the last river these individuals coexist in sympatry with brown trout of indigenous Da23c haplotype. Since Atlantic haplotype was not considered indigenous for Balkan Peninsula, it has been probably introduced there by stocking. Analysis of nuclear gene lactate dehydrogenase showed that individuals of two lineages occurring in sympatry interbreed. Data software analyzes of eight microsatellite loci revealed the existence of five separated populations in Eastern Serbia: (1) Crni Timok drainage area, (2) River Kožica, (3) River Rečka, (4) Rivers Vratna and Zamna, and (5) River Mala Boljetinska and River Zlatica, indicating a potential communication and gene flow between these populations..."
