Following short-term local applications of high doses of N-methyl-N-nitrozourea and 7,2-dimethylbenz(a)antracen, the intercellular adhesion in the distal colon epithelium of ice retains increased at least for a month. The magnitude of this shift and its duration ops both with moving

N-Nitroso compounds may well rank high among the genotoxic carcinogens present in our environment. Small amounts of such compounds may be formed in the human stomach after consumption of high-nitrate vegetables. Volatile nitrosamines can be conveniently determined but reliable methods

The single-dose toxicokinetics of monomethylamine has been characterized in the rat by HPLC assay of serial blood samples. Biphasic first-order elimination was observed following an iv bolus dose of 19 mumol/kg with a terminal half-life of 19.1 +/- 1.3 min
The in vivo nitrosation capacity of third-instar larvae of Drosophila melanogaster was assessed using the wing somatic mutation and recombination test (SMART). Larvate derived from two different crosses, the standard cross (ST) and the high bioactivation cross (HB) both involving
Colloids and surfaces. B, Biointerfaces, 51(1), 10-15 (2006-06-30)
The present study highlights the fact that the effect of additives (urea, monomethylurea, thiourea) on the supramolecular assemblies and proteins is strikingly similar. To investigate the effect, a viscometeric study on sphere-to-rod transition (s-->r) was undertaken in a system (3.5%
