In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.
One example is below.
Q: Context: Chronic rhinosinusitis (CRS) is a heterogeneous disease with an uncertain pathogenesis. Group 2 innate lymphoid cells (ILC2s) represent a recently discovered cell population which has been implicated in driving Th2 inflammation in CRS; however, their relationship with clinical disease characteristics has yet to be investigated. The aim of this study was to identify ILC2s in sinus mucosa in patients with CRS and controls and compare ILC2s across characteristics of disease. A cross-sectional study of patients with CRS undergoing endoscopic sinus surgery was conducted. Sinus mucosal biopsies were obtained during surgery and control tissue from patients undergoing pituitary tumour resection through transphenoidal approach. ILC2s were identified as CD45(+) Lin(-) CD127(+) CD4(-) CD8(-) CRTH2(CD294)(+) CD161(+) cells in single cell suspensions through flow cytometry. ILC2 frequencies, measured as a percentage of CD45(+) cells, were compared across CRS phenotype, endotype, inflammatory CRS subtype and other disease characteristics including blood eosinophils, serum IgE, asthma status and nasal symptom score. 35 patients (40% female, age 48 ± 17 years) including 13 with eosinophilic CRS (eCRS), 13 with non-eCRS and 9 controls were recruited. ILC2 frequencies were associated with the presence of nasal polyps (P = 0.002) as well as high tissue eosinophilia (P = 0.004) and eosinophil-dominant CRS (P = 0.001) (Mann-Whitney U). They were also associated with increased blood eosinophilia (P = 0.005). There were no significant associations found between ILC2s and serum total IgE and allergic disease. In the CRS with nasal polyps (CRSwNP) population, ILC2s were increased in patients with co-existing asthma (P = 0.03). ILC2s were also correlated with worsening nasal symptom score in CRS (P = 0.04).
Question: Are group 2 innate lymphoid cells ( ILC2s ) increased in chronic rhinosinusitis with nasal polyps or eosinophilia?
A: As ILC2s are elevated in patients with CRSwNP, they may drive nasal polyp formation in CRS. ILC2s are also linked with high tissue and blood eosinophilia and have a potential role in the activation and survival of eosinophils during the Th2 immune response. The association of innate lymphoid cells in CRS provides insights into its pathogenesis.
Rationale: The output says that ILC2s are elevated in patients with CRSwNP and that they may drive nasal polyp formtion in CRS. The output also says that ILC2s are linked with blood eosinophilia and hence, it completely answers the question on the basis of the information in the context.
Q: Context: The effect of litter size and suckling intensity on the expression of KiSS-1 mRNA in the arcuate nucleus (ARC) of rats were evaluated.', 'Thirty two pregnant and four non-lactating ovariectomized (as control group) rats were used in this experiment. Lactating rats were allotted to eight equal groups. In three groups, litter size was adjusted to 5, 10, or 15 pups upon parturition and allowed to suckle their pups continuously by 8 days postpartum. In the other three groups, litter size was adjusted to five upon birth; the pups were separated from the dams for 6 hr on day 8 postpartum, after which the pups were allowed to suckle their dams for 2.5, 5, or 7.5 min prior to killing the dams. Two groups of lactating rats with either 10 or 15 pups were separated from their pups for 6 hr on day 8 postpartum, after which the pups were allowed to suckle their dams for 5 min before the dams were killed on day 8 postpartum. The ARC was removed and the expression of KiSS-1 mRNA was evaluated, using real-time PCR.', 'The expression of KiSS-1 mRNA in the ARC was decreased as the litter size and intensity of suckling stimulus were increased. The effect of suckling intensity on the expression of KiSS-1 mRNA was more pronounced than that of litter size.\Question: Do increased litter size and suckling intensity inhibit KiSS-1 mRNA expression in rat arcuate nucleus?
A:
Increased litter size and suckling intensity decreased KiSS-1 mRNA expression in the ARC which may contribute to lactation anestrus in rat.
