Wheat straw pretreated with chemicals as well as hot water was subjected to degradation by edible mushroom Pleurotus ostreatus. Lignin, cellulose and hemicelluloses component of both chemically as well as hot water treated wheat straw was degraded by the fungus and in turn the edible and nutritious fruiting body of the mushroom was produced. Biodegradation of wheat straw in terms of loss of lignin, cellulose and hemicellulose showed positive correlation with cellulases, xylanase, laccase and polyphenol oxidase (PPO) activity of the fungus. During vegetative growth of the fungus, lignin degradation was faster and during fructification, lignin degradation was slower than cellulose and hemicellulose. The carbon content of the wheat straw decreased while, nitrogen content increased during degradation of the waste. Hot water treated wheat straw supported better production of enzymatic activity and degraded more efficiently than chemically sterilized substrate. The cumulative yield and biological efficiency (BE) of the mushroom was maximum on the hot water treated substrate. Degradation of the hot water treated wheat straw was better and faster than chemically treated substrate. © 2014. Source

Methylenetetrahydrofolate reductase (MTHFR) is a key enzyme in the metabolism of folate, whose role in bipolar disorder is controversial. The aim of the present study was to assess the risk of MTHFR C677T polymorphism for bipolar disorder. The author performed a meta-analysis and pooled data from individual case-control studies that examined the association between C677T polymorphism and bipolar disorder (meta-analysis: 8 studies, 1457 cases and 2169 controls).The pooled Odd Ratios (OR) were estimated by both fixed effects and random effects models. The meta-analysis with fixed effects showed that there was 71% heterogeneity between the eight studies. The fixed effect pooled OR was 1.07 (95% CI; 0.98 to 1.17) and Cochran Q was 24.13 (df = 7; p=0.0011). The study is significant and shows meager association. The random effect pooled OR was 1.07(95% CI; 0.87 to 1.32) and Cochran Q was 24.13 (df = 7; p=0.0011). The random effect pooled OR was also significant and shows meager association between MTHFR C677T genotype and bipolar disorder. Source

Background: Previous studies concerning the association between the 5,10-methylenetetrahydrofolate reductase (MTHFR) C677T gene polymorphism with lung cancer in Asian populations have provided inconclusive findings. Aim: A meta-analysis was performed to investigate a more reliable association between MTHFR C677T polymorphism and lung cancer in Asians. Materials and Methods: A comprehensive search was conducted to identify all case-control studies of MTHFR polymorphisms and lung cancer in Asia, using odds ratios (ORs) with 95% confidence intervals (CIs) to assess the strength of any association. Results: Meta-analysis results suggested that the MTHFR C677T polymorphism contributed to an increased lung cancer risk in Asian populations (for T vs C: OR=1.11, 95%CI=1.0-1.23; for CT vs CC: OR= 1.1, 95%CI= 0.95-1.2 ; for TT+CT vs CC: OR=1.13, 95%CI=1.0-1.30; for TT vs CC: OR=1.25, 95%CI=1.01-1.30; for TT vs CT+CC: OR=1.16, 95%CI=1.0-1.36). Conclusions: MTHFR C677T polymorphism is significantly associated with lung cancer in Asians. Source

Edible oyster mushroom Pleurotus sapidus was cultivated, on pea pod shell, cauliflower leaves, radish leaves, brassica straw in various combinations of paddy straw. The mushroom failed to grow on these vegetable wastes separately. However, it grew very well on these vegetable wastes when mixed with various combinations of paddy straw as substrate. Total yield and biological efficiency of the mushroom cultivated on substrate containing 20% and 30% vegetable wastes mixed with 70% and 80% (w/w) of paddy straw was found to be better, when compared with yield and efficiency obtained with paddy straw alone (100%). The protein content in the fruit bodies was found to be higher in the mushroom grown on paddy straw mixed with vegetable wastes than that obtained with paddy straw alone. Similarly, six amino acids (Leu, Ile, Val, Thr, Met and Phe) showed a significant increase when the mushroom was grown on a mixed substrate containing both vegetable wastes and paddy straw. On the contrary, the total sugar and reducing sugar content declined in the mushroom grown on the mixture of paddy straw and other wastes, when compared with the results obtained with paddy straw alone. © 2012.

The syntheses of a series of some substituted-1, 2, 4-triazole derivatives are described. The reaction of sodium salt of α-sulphonated of stearic acid hydrazide (1) with carbon disulphide in alcoholic KOH yielded the corresponding sodium 1-(4-amino-5-mercapto-4H-[1, 2, 4]-triazol-3yl)- heptadecane-1-sulfonate (2). The reaction of compound (2) with urea, chloroacetyl chloride, chloroacetaldehyde and phenacyl bromides yielded the substituted 1, 2, 4-triazole derivatives (3), (4), (5) and (6) respectively. All the synthesized compounds were characterized by IR, PMR, Mass spectral data and elemental analyses. All newly synthesized compounds have been assayed for their antibacterial activities against S. aureus, E. coli, B. subtilis and P. aeruginosa. Source
