W Lijinsky et al.
In vivo (Athens, Greece), 5(2), 85-89 (1991-03-01)
A number of nitrosamines that have been studied by administration to rats as solutions in drinking water have been examined by gavage administration of similar doses, for assessment of the role of pharmacokinetics in organ-specific carcinogenesis. Methylnitrosoethylamine was more effective
W Lijinsky et al.
Carcinogenesis, 3(8), 911-915 (1982-01-01)
A comparison was made of the carcinogenic effectiveness of some cyclic nitrosamines containing oxygen in the ring. The compounds were administered to F344 rats at approximately equimolar concentrations in drinking water. Nitrosomorpholine, nitroso-1,3-oxazolidine and nitrosotetrahydro-1,3-oxazine were of similar potency and

Several hypotheses are established to describe the formation and progression of foci of altered hepatocytes (FAH). A common model of hepatocarcinogenesis is the mutation model (MM), which is based on the assumption that cells have to undergo multiple successive changes

Hepato-gastroenterology, 58(112), 2032-2035 (2012-01-12)
Concern that much controversy exists with respect to the role of estrogen in hepatocarcinogenesis prompted us to examine the effect of estrogen, at physiological concentrations, on our established HCC rat model induced by diethylnitrosamine and N-nitrosomorpholine. Female Sprague-Dawley rats were
D Slamenova et al.
Neoplasma, 55(4), 280-285 (2008-05-29)
N-nitrosomorpholine (NMOR) belongs to the group of N-nitrosamines and represents a known hepatocarcinogen. Exposure to this compound is considered to be a potential health hazard to humans. There is, however, considerable evidence that the effect of many carcinogenic agents can

Carcinogenesis and Epigenetics

Cancer research has revealed that the classical model of carcinogenesis, a three step process consisting of initiation, promotion, and progression, is not complete.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
