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.

Ex Input:
Context: Sigma-1 receptors are involved in the pathophysiological process of several neuropsychiatric diseases such as epilepsy, depression. Allosteric modulation represents an important mechanism for receptor functional regulation. In this study, we examined antidepressant activity of the latest identified novel and selective allosteric modulator of sigma-1 receptor 3-methyl-phenyl-2, 3, 4, 5-tetrahydro-1H-benzo[d]azepin-7-ol (SOMCL-668).', 'A single administration of SOMCL-668 decreased the immobility time in the forced swimming test (FST) and tailing suspended test in mice, which were abolished by pretreatment of sigma-1 receptor antagonist BD1047. In the chronic unpredicted mild stress (CUMS) model, chronic application of SOMCL-668 rapidly ameliorated anhedonia-like behavior (within a week), accompanying with the enhanced expression of brain-derived neurotrophic factor (BDNF) and phosphorylation of glycogen synthase kinase 3β (GSK3β) (Ser-9) in the hippocampus. SOMCL-668 also rapidly promoted the phosphorylation of GSK3β (Ser-9) in an allosteric manner in vitro. In the cultured primary neurons, SOMCL-668 enhanced the sigma-1 receptor agonist-induced neurite outgrowth and the secretion of BDNF.\Question: Does allosteric Modulation of Sigma-1 Receptors elicit Rapid Antidepressant Activity?

Ex Output:
SOMCL-668, a novel allosteric modulator of sigma-1 receptors, elicits a potent and rapid acting antidepressant effect. The present data provide the first evidence that allosteric modulation of sigma-1 receptors may represent a new approach for antidepressant drug discovery.


Ex Input:
Context: The basis of the treatment of painful diabetic neuropathy is the use of drugs that block the transmission of pain (antineuritics) and a good metabolic control of underlying disease.', 'To describe the outcomes of 17 type-2 diabetics with painful neuropathy, treated between 1988 and 2005 with symptomatic therapy plus intensified insulin.', 'Review of medical records of 17 type-2 diabetic patients, aged 63+/-11 years and a duration of diabetes of 15+/-8 years. All patients received intensified insulin therapy with 0.35 units/kg of NPH insulin (2/3 before breakfast and 1/3 evening meal), plus capillary glucose measurements and regular insulin (with sliding-scale centered in approximately 0.1 units/kg) before the 3 main meals. All patients were also treated with gabapentin, nortriptyline or clomipramine. Pain was assessed using a visual analog score of 10 points.', 'After 1 year, glycosilated hemoglobin decreased from 10.0+/-1.4% to 7.7+/-1.2% (p approximately =0.003). Pain decreased from 10 to 5.1+/-3.3 at one month, 2.3+/-3.2 at six months, and 3.1+/-3.6 at 1 year (p <0.01). There was a direct statistical correlation between the reduction of HbA1C and pain decline (r =0.736; p =0.037). Pain scores were lower than those reported elsewhere for Pregabalin (n =76; p =0.05), Lamotrigine (n =27; p <0.0005), Topiramate (n =208; p <0.005), and Gabapentin (n =84; p <0.025). The lack of difference to Sodium Valproate (n =21; p =0.07) had borderline significance.\Question: Is [ Intensified insulin therapy plus antineuritic medication more effective than antineuritics alone in painful diabetic neuropathy ]?

Ex Output:
The addition of intensified insulin therapy to the symptomatic treatment of painful neuropathy in type-2 diabetics, significantly enhanced the reduction of pain. The lowering of glycosilated hemoglobin was a significant predictor of success in pain reduction.


Ex Input:
Context: The antifibrotic substance pirfenidone and the angiotensin II type I receptor antagonist candesartan cilexetil, given alone and in combination, were tested in rats with chronic anti-glomerular basement membrane glomerulonephritis (anti-GBM GN).', 'Male Wistar rats with anti-GBM GN were treated for 8 weeks with candesartan (4 mg/kg body weight/day), pirfenidone (500 mg/kg body weight/day) or a combination of both drugs. One GN group received no treatment and untreated non-GN-rats were used as controls. Blood pressure and urinary protein excretion were measured after 3 and 7 weeks. Kidney histology was complemented by ultrastructural investigation and by quantification of collagen Ialpha mRNA.', 'The percentage of glomeruli with adsorption droplets in podocytes correlated well with the amount of proteinuria (r = 0.873, P<0.01) and was significantly lowered in rats treated with candesartan (8.3 vs GN 24.6%), pirfenidone (9.8%) and combined treatment (2.6%, P<0.05 vs candesartan alone). A comparable lowering was seen for segmental sclerosis (GN 11%, candesartan 0.7%, P<0.05 vs GN, pirfenidone 1.8%, P = 0.09 vs GN, candesartan/pirfenidone 0.1%, P>0.5 vs candesartan alone). Cortical collagen Ialpha mRNA expression was significantly decreased in all treatment groups. Ultrastructural investigation showed an amelioration of basement membrane alterations and podocyte damage in the treatment groups. Candesartan caused significant blood pressure reduction and the effect was significantly enhanced by combination therapy after 3 weeks. Rats treated with pirfenidone showed blood pressure values similar to control rats.\Question: Do pirfenidone and candesartan ameliorate morphological damage in mild chronic anti-GBM nephritis in rats?

Ex Output:

Pirfenidone has a beneficial effect on morphological changes in anti-GBM GN comparable with candesartan although with a trend to slightly better results with candesartan treatment. Moreover, our results suggest an additive effect of combination treatment.
