Oxidative DNA damage in patients infected by Helicobacter pylori
(Ii Intercontinental Congress of Pathology, 2004-01-01) [Trabalho apresentado em evento]
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 ...
Biocompatibility in vitro tests of mineral trioxide aggregate and regular and white Portland cements
(Journal of Endodontics, 2005-08-01) [Artigo]
Mineral trioxide aggregate (MTA) and Portland cement are being used in dentistry as root end-filling materials. However, biocompatibility data concerning genotoxicity and cytotoxicity are needed for complete risk assessment ...
Genotoxicity in primary human peripheral lymphocytes after exposure to regular and white mineral trioxide aggregate
(Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology and Endodontology, 2006-11-01) [Artigo]
Objective: Taking into consideration that DNA damage plays an important role in carcinogenesis, the purpose of this study was to evaluate whether regular and white mineral trioxide aggregate (MTA) are able to induce genetic ...
Evaluation of DNA damage and lipoperoxidation of propofol in patients undergoing elective surgery
(European Journal of Anaesthesiology, 2009-08-01) [Artigo]
Background and objectives Inhaled anaesthetics have been studied regarding their genotoxic and mutagenic potential in vivo. Propofol differs from volatile anaesthetics because it does not show mutagenic effects and it has ...
Lentinula edodes (Shiitake) modulates chemically induced mutagenesis by enhancing pitting
(Journal of Medicinal Food, 2013-08-01) [Artigo]
This study was undertaken to understand how Lentinula edodes modulates in vivo mutagenesis induced by alkylating agents in bone marrow and peripheral blood as described in our previous article. Male Swiss mice were pretreated ...
Relationship between gene polymorphisms and DNA damage in morbid obese women
(Environmental and Molecular Mutagenesis, 2011-10-01) [Resumo]
Cholesterol reduction and lack of genotoxic or toxic effects in mice after repeated 21-day oral intake of lemongrass (Cymbopogon citratus) essential oil
(Food and Chemical Toxicology, 2011-09-01) [Artigo]
Cymbopogon citratus (lemongrass) is currently used in traditional folk medicine. Although this species presents widespread use, there are no scientific data on its efficacy or safety after repeated treatments. Therefore, ...
DNA damage and aberrant crypt foci as putative biomarkers to evaluate the chemopreventive effect of annatto (Bixa orellana L.) in rat colon carcinogenesis
(Mutation Research: Genetic Toxicology and Environmental Mutagenesis, 2005-04-04) [Artigo]
Chemoprevention opens new perspectives in the prevention of cancer and other degenerative diseases. Use of target-organ biological models at the histological and genetic levels can markedly facilitate the identification ...
