MS222 does not induce primary DNA damage in fish
(Aquaculture International, 2007-04-01) [Artigo]
The genotoxicity of the anaesthetic MS222 (tricaine) was analysed in fish under both in vivo and in vitro conditions. Based on results of the single cell gel/Comet assay, MS222 had no direct genotoxic effect on the ...
Relationships between cagA, vacA, and iceA genotypes of Helicobacter pylori and DNA damage in the gastric mucosa
(Environmental and Molecular Mutagenesis, 2004-01-01) [Artigo]
Helicobacter pylori (H. pylori) is believed to dispose carriers to gastric cancer by inducing chronic inflammation. The inflammatory processes may result in the generation of reactive oxygen and nitrogen species that damage ...
Tomato oleoresin inhibits DNA damage but not diethylnitrosamine-induced rat hepatocarcinogenesis
(Experimental and Toxicologic Pathology, 2008-06-01) [Artigo]
Various studies have shown that lycopene, a non-provitamin A carotenoid, exerts antioxidant, antimutagenic and anticarcinogenic activities in different in vitro and in vivo systems. However, the results concerning its ...
Mate attenuates DNA damage and carcinogenesis induced by diethylnitrosamine and thermal injury in rat esophagus
(Food and Chemical Toxicology, 2009-07-01) [Artigo]
Drinking hot mate has been associated with risk for esophageal cancer in South America. Thus. the aims of this study were to evaluate the modifying effects of mate intake on DNA damage and esophageal carcinogenesis induced ...
