N-Nitrosamine formation by cultures of several microorganisms.
Of 38 pure cultures of microorganisms tested, only one, Pseudomonas stutzeri, was capable of forming dimethylnitrosamine from dimethylamine and nitrite during growth. Resting cells of P. stutzeri, Cryptococcus terreus, Escherichia coli, and Xanthomonas campestris formed dimethylnitrosamine, although no nitrosamine was found in growing cultures of the latter three organisms. No nitrosamine was p...
متن کاملevaluation of n-nitrosamine formation in routine potato cooking
conclusions nitrosamine was formed with conventional potato baking methods with the most nitrosamine formation found on the surface fried samples. nitrites amount in baked potatoes decreased. generally, the amount of nitrosamine in baked potato samples was lower than acceptable limits. results fried samples that were measured by the gas chromatography method had the highest average levels of ni...
متن کاملTransnitrosylation Directs TRPA1 Selectivity in N-Nitrosamine Activators s
S-Nitrosylation, the addition of a nitrosyl group to cysteine thiols, regulates various protein functions to mediate nitric oxide (NO) bioactivity. Recent studies have demonstrated that selectivity in protein S-nitrosylation signaling pathways is conferred through transnitrosylation, a transfer of the NO group, between proteins via interaction. We previously demonstrated that sensitivity to act...
متن کاملClonal analysis of urothelial carcinomas in C3H/HeN<-->BALB/c chimeric mice treated with N-butyl-N-(4-hydroxybutyl)nitrosamine.
The histological background for multifocal and metachronous development of urothelial carcinomas remains equivocal, although accumulated genetic evidence suggests monoclonal origin of multiple urothelial carcinomas. Clonal development of various preneoplastic and neoplastic urothelial lesions of C3H<-->BALB/c chimeric mice induced by N-butyl-N-(4-hydroxybutyl)nitrosamine (BBN) was immunohistoch...
