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
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

International journal of experimental pathology, 87(5), 343-359 (2006-09-13)
Adult hepatocytes and liver-cell progenitors play a role in restoring liver tissue after injury. For the study of progenitor cells in liver repair, experimental models included (a) surgical removal of liver tissue by partial hepatectomy; (b) acute injury by carbontetrachloride;

Toxicology mechanisms and methods, 20(2), 45-52 (2010-01-27)
Nitrites are ubiquitous environmental contaminants present in drinking water and foods. Nitrosamines can be formed endogenously from nitrate and nitrite and secondary amines or may be present in food, tobacco smoke, and drinking water. The major goal of this work
M Tatsuta et al.
Cancer letters, 119(1), 109-113 (2008-04-01)
The effects of prolonged administration of the diuretic amiloride on hepatocarcinogenesis induced by N-nitrosomorpholine (NNM) and the labeling index of the liver were investigated in male Sprague-Dawley rats. Rats were given drinking water containing NNM for 8 weeks and received

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

Questions

  1. Buenos días, este material es líquido, ¿podrían por favor indicar cual es la concentración de NMOR en el vial? No la he localizado en el CoA ni en la información disponible en web. Muchas gracias por adelantado

    1 answer
    1. This product has a melting point of 29 °C. Depending on temperature, it may be in the form of a solid or liquid. This product is considered to be "neat" or 100% pure. Thus, a solution may be prepared at a defined concentration by weighing. The density of the liquid form, as reported in the literature, is 1.2 - 1.3 g/ml.
