nitrosamides

01/01/1984 - "The chemical degradation of five N-nitrosamides used widely for the experimental induction of cancer has been studied with the goal of identifying, and experimentally validating, reliable methods that can be recommended for the destruction of carcinogenic N-nitrosoureas and related compounds in laboratory wastes. "
01/01/1972 - "Since 7 of the 14 prophage-inducing nitrosamidines and nitrosamides reported thus far have carcinostatic activity in rodent tumor systems, it is concluded that the induction test may provide a useful screen for the detection of potential antitumor compounds. "
02/01/1988 - "An improved procedure for chemically decontaminating residues of nitrosoureas and related N-nitroso compounds ("nitrosamides") commonly used in the cancer research laboratory is proposed. "
05/01/2004 - "N-Nitrosamines and nitrosamides can initiate cancer. "
11/01/1977 - "It is likely that N-nitroso compounds formed in this way, especially nitrosamides, could reach the colon and contribute to the induction of colon tumors."

08/01/1996 - "Few chemicals are effective in causing brain tumors experimentally after systemic administration of low doses; a notable exception is one group of N-nitroso compounds, the nitrosamides (in particular the nitrosoureas). "

01/01/1990 - "As Vitamin C prevents nitrosation and as precursors of nitrosamides are present in prepared foods, further dietary studies with hypotheses based on N-nitroso carcinogenesis are required. "
01/01/2017 - "Because nitrosamides are generally more stable than α-hydroxynitrosamines and can also alkylate DNA, nitrosamides may play a role in carcinogenesis. "
03/01/1997 - "The results suggest that human endogenous exposure to NAD in the high risk area for GC be higher than that in the low risk area; CAG and dysplasia may play a role in human gastric carcinogenesis by N-nitrosamides."
01/01/1984 - "Possible implications of the presence of nitrite in carcinogenesis in digestive tracts are discussed on the basis of facile formation and decomposition of nitrosamides and the intermediacy of diazo compounds."
01/01/1984 - "Nitrosamide carcinogenesis: nitrosation of amide linkages and facile decomposition of resulting nitrosamides."

08/01/2000 - "progress of gastric cancer etiology: N-nitrosamides 1999s."
03/01/1997 - "[Comparison of total N-nitrosamides in fasting gastric juice from subjects in high and low risk areas for gastric cancer]."
01/01/1991 - "These findings indicate that N-nitrosamides may play an important role in causing gastric cancer in China."
01/01/1991 - "Role of nitrosamides in the high risk for gastric cancer in China."
01/01/1982 - "Thus, conditions conducive to gastric cancer are associated with higher levels of compounds responding to group analysis as N-nitrosamines and/or N-nitrosamides."

11/01/1999 - "To study formation of N-(nitrosomethyl) urea (NMU), which is categorized as N-nitrosamides -- a sort of strong chemical carcinogen, by perfusion with fish sauce via pig stomach fistula, which is used daily as cooking flavor by local residents in Changle County, Fujian Province, a highly-prevalent area for gastric cancer.
