Effects of fasting and intermittent fasting on rat hepatocarcinogenesis induced by diethylnitrosamine
(Teratogenesis Carcinogenesis and Mutagenesis, 2002-01-01) [Artigo]
The influences of fasting on DEN-initiation and of intermittent fasting (IF) on the rat liver chemical carcinogenesis process were evaluated in a 52-week long assay. Three groups of adult male Wistar rats were used: Groups ...
Mushroom-derived preparations in the prevention of H2O2-induced oxidative damage to cellular DNA
(Teratogenesis Carcinogenesis and Mutagenesis, 2002-03-06) [Artigo]
Aqueous extracts of the sporophores of eight mushroom species were assessed for their ability to prevent H2O2-induced oxidative damage to cellular DNA using the single-cell gel electrophoresis (Comet) assay. The highest ...
No mutations found in exons of TP53, H-RAS and K-RAS genes in liver of male Wistar rats submitted to a medium-term chemical carcinogenesis assay
(Jornal Brasileiro de Patologia e Medicina Laboratorial, 2002-07-01) [Artigo]
O teste padrão para identificar o potencial cancerígeno de compostos químicos é o estudo de longa duração em roedores, não realizado no Brasil. Nosso laboratório estabeleceu um teste alternativo de média duração (ensaio ...
