(Food and Chemical Toxicology, 2004-10-01) [Artigo]
Annatto (Bixa orellana L.) is a natural food colorant extensively used in many processed foods, especially dairy products. The lower cost of production and the low toxicity, make annatto a very attractive and convenient ...
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 ...
Modifying effect of propolis on dimethylhydrazine-induced DNA damage but not colonic aberrant crypt foci in rats
(Environmental and Molecular Mutagenesis, 2005-01-01) [Artigo]
Propolis is a honeybee product with several biological and therapeutic properties, including antimutagenic and anticarcinogenic activities. The effects of an aqueous extract of propolis (AEP) were evaluated on the formation ...
Protective action of propolis on the rat colon carcinogenesis
(Teratogenesis Carcinogenesis and Mutagenesis, 2002-01-01) [Artigo]
Propolis is a honeybee product with several biological and therapeutical properties. Its effect on the process of colon carcinogenesis and DNA damage were evaluated in the male Wistar rats using the aberrant crypt foci ...
Black bean (Phaseolus vulgaris L.) as a protective agent against DNA damage in mice
(Food and Chemical Toxicology, 2003-12-01) [Artigo]
This study was designed to evaluate the toxicogenetic or protective effect of cooked and dehydrated black beans (Phaseolus vulgaris L.) in bone marrow and peripheral blood cells of exposed mice. The frequency of micronuclei ...
