In vivo nitrosation of amidopyrine in humans: use of 'ethanol effect' for biological monitoring of N-nitrosodimethylamine in urine.
Under normal conditions a possible N-nitrosodimethylamine formation in vivo cannot directly be monitored in urine due to high metabolic conversion rate (greater than 99.9%). Own experiments showed an increased excretion rate (up to 2.4%) if ethanol was administered simultaneously. This model was used for monitoring experiments with respect to in vivo formation of N-nitrosodimethylamine. Amidopy...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...

Special diets that were extremely low in protein (5.5%) and high in carbohydrate were used to test the effect of nicotinamide on A/-nitrosodimethylamine-induced Carcinogenesis in Holtzman albino rats. The level of nicotinamide in the three diets ranged from 0 mg/kg of food to 50 mg/kg to 500 mg/kg. During the treatment with these diets (5 weeks) and the carcinogen (18 days), the renal and hepat...

متن کاملN-nitrosation and denitrosation on lysine residues of histones.
Increased immunoactivity of (-nitrosolysine was detected in Western blot in peroxynitrite-reacted histones H2A, H3 and H4. The N-nitrosation may be reversible as indicated by the decreased immunoactivity via either subsequent incubation with reduced glutathione or 48-hour dialysis and 48-hour storage at 4 degrees C. Nonetheless, the biological significance of N-nitrosation of protein lysine is ...
