Induction of Colonic Aberrant Crypts in Mice by Feeding Apparent N-Nitroso Compounds Derived From Hot Dogs [PDF]

, 2012
Nitrite-preserved meats (e.g., hot dogs) may help cause colon cancer because they contain N-nitroso compounds. We tested whether purified hot-dog-derived total apparent N-nitroso compounds (ANC) could induce colonic aberrant crypts, which are putative ...

Development and validation of a simple spectrophotometric method for the determination of methyldopa in both bulk and marketed dosage formulations

Brazilian Journal of Pharmaceutical Sciences, 2014
A simple, precise, sensitive, rapid, specific and economical spectrophotometric method was developed to determine methyldopa (MTD) content in bulk and pharmaceutical dosage formulations. The proposed method was based on the formation of a colored product

Regulation of glutathione transferase P1-1 by S-nitrosation [PDF]

, 2014
S-Nitrosation is a post-translational modification of protein cysteine residues, which occurs in response to cellular oxidative stress. Although it is increasingly being linked to physiologically important processes, the molecular basis for protein ...

Kinetic study of an autocatalytic reaction: nitrosation of formamidine disulfide [PDF]

, 2013
The reaction kinetics for the acid nitrosation of formamidine disulfide (FDS) show an autocatalytic behavior that arises from the fact that the thiocyanate ion formed as a product acts as a powerful catalyst for the nitrosation reaction.
