Background: This study was undertaken to investigate whether treatment with vitamin E and N acetyl cystein protects rat sperm by inhibiting reactive oxygen species generation induced by lead (Pb) exposure. Materials and Methods: After an acclimatization period of one week, 20 Male rats were divided into 4 groups of 5 rats each. Animals within different treatment groups were maintained on their ...

Plackett-Burman experimental design was used to screen important medium components influencing the production of polyribosyl ribitol phosphate by Haemophilus influenzae type-B under submerged fermentation. Eleven media parameters such as Glutamic acid, Yeast extract, cystein, dextrose, NAD, heamin, NaCl, NH4Cl, Na2HPO4, KCl, and MgSO4.7H2O were screened in twelve experimental runs as per the de...

It is well known that the cyanides and the nitriles when given to mammals leave the body in part as sulfocyanides. This suggests that they combine with the labile sulfur group of the albumins of the cell, and it was this fact which led us to undertake a study of the spontaneous oxidation of cystein. It is not necessary to recapitulate the evidence that the cyanides act on cell-respiration, sinc...

Three cystein-tagged cellulases co-immobilized on AuNP and Au-MSNP for the hydrolytic degradation of cellulose. The biochemical properties, stabilities, activities and reusability of these co-immobilized systems were compared to those of mixtures of free cellulases.

We report a turn-on fluorescent sensor based on nitrothiophenolate boron dipyrromethene (BODIPY) derivatives for the discrimination of cystein (Cys) from homocystein (Hcy) and glutathione (GSH). The sensor was applied for detection of Cys in living cells.

introduction: up to 12% of patients undergoing coronary artery bypass graft have pulmonary complications. smoking can cause a six-time increase in pulmonary complication after major surgery. the most common pulmonary changes after cabg are decrease in frc, vc and atelectasis. in this study, the effect of oral n-acetyl-cystein in reduction of severity of hypoxemia and atelectasis in current smok...
