Lycopene activity against chemically induced DNA damage in Chinese hamster ovary cells
(Toxicology in Vitro, 2007-08-01) [Artigo]
Lycopene is a natural pigment synthesized by plants and microorganisms, and it is mainly found in tomatoes. It is an acyclic isomer of P-carotene and one of the most potent antioxidants. Several studies have demonstrated ...
Effects of diuron on toxicological and hematological parameters and lymphohematopoietic organs in a rat chemical hepatocarcinogenesis model
(Annual Review of Biomedical Sciences, 2005) [Artigo]
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 ...
Lack of chemoprevention of dietary Agaricus blazei against rat colonic aberrant crypt foci
(Human & Experimental Toxicology, 2008-06-01) [Artigo]
The mushroom Agaricus blazei (Ab) has been widely used in folk medicine to treat various diseases including cancer. No information is available on its possible protective effects on the development of colon cancer. The ...
Farming technology, biochemistry characterization, and protective effects of culinary-medicinal mushrooms Agaricus brasiliensis S. Wasser et al. and Lentinus edodes (Berk.) Singer: Five years of research in Brazil
(International Journal of Medicinal Mushrooms, 2005-07-04) [Artigo]
The biotechnology, biochemical characterization, and protective effects of the himematsutake and shiitake mushrooms were studied for the Thematic Project, from 1998 to 2003. A new species, Agaricus Brasiliens is Wasser et ...
Protective effects of Ginkgo biloba against rat liver carcinogenesis
(Chemico-biological Interactions, 2008-05-09) [Artigo]
Ginkgo biloba (EGb) has been proposed as a promising candidate for cancer chemoprevention and has shown protective effects on the liver against chemically induced oxidative injury and fibrosis. The potential beneficial ...
Diuron lacks promoting potential in a rat liver bioassay
(Toxicologic Pathology, 2007-01-01) [Artigo]
The promoting activity of the herbicide Diuron was evaluated in a medium-term rat liver carcinogenesis bioassay that uses as endpoint immunohistochemically identified glutathione S-transferase positive (GST-P+) foci. Male ...
Screening for In Vitro and In Vivo Antitumor Activities of the Mushroom Agaricus Blazei
(Nutrition and Cancer-an International Journal, 2009-01-01) [Artigo]
We have investigated the in vitro antitumor activity of the mushroom Agaricus blazei Murill on human cancer cell lines as well as its potential anticancer activity in a model of rat colon carcinogenesis. The in vitro ...
Chronic ethanol intake promotes double gluthatione S-transferase transforming growth factor-alpha-positive hepatocellular lesions in male Wistar rats
(Cancer Science, 2008-02-01) [Artigo]
The chronic ethanol intake influence on the gluthatione S-transferase (GST-P) and transforming growth factor alpha (TGF-alpha) expression in remodeling/persistent preneoplastic lesions (PNLs) was evaluated in the resistant ...
