esophageal neoplasms/トウモロコシ

Retrovirally induced immunosuppression may elevate the incidence of chemically induced cancers. A proposed hypothesis to explain this relationship is the increased free radical activity observed during retroviral infection and carcinogen activation. We previously found that vitamin E retarded growth

N-Nitroso-1,2,3,6-tetrahydropyridine (N-nitroso-delta3-piperidine), N-nitroso-1,2,3,4-tetrahydropyridine (N-nitroso-delta2-piperidine) and N-nitroso-3,4-epoxypiperidine were tested for carcinogenicity in Fischer 344 rats. The unsaturated nitrosamines were administered in drinking water (100 mg/l).

Contamination of maize ( Zea mays ) with fumonisins produced by the fungus Fusarium verticillioides is a global concern for food safety. Fumonisins are a group of polyketide-derived secondary metabolites linked to esophageal cancer and neural tube birth defects in humans and numerous toxicoses in

In Brazil, the southern region has the highest incidence of esophageal cancer and also the highest production and consumption of corn (Zea mays) products. Corn samples intended for human consumption from the western, northern, and southern regions of the state of Santa Catarina, southern Brazil, had

Nitroso-N-methylurethane and nitroso-N-ethylurethane were administered to groups of 20 female F344 rats in corn oil solution by gavage. Each rat received once a week 0.2 ml of solution containing 7 mg/ml or 1.75 mg/ml of the methyl compound or 8 mg/ml or 2 mg/ml of the ethyl compound for 20 weeks.

OBJECTIVE The incidence of esophageal adenocarcinoma is on the rise in the United States. In this ecological study using the Surveillance, Epidemiology, and End Results (SEER) program (1973-2001) and national food consumption data (1909-1997), we evaluated the correlation between secular trends of

Non-steroidal anti-inflammatory drugs (NSAIDs) play a significant role in the chemoprevention of cancer. We recently showed the chemopreventive response of a NSAID, 2-[(3-chloro-2-methylphenyl)amino]benzoic acid) known as tolfenamic acid (TA) in N-nitrosomethylbenzylamine (NMBA)-induced esophageal
