Inhibition of ozone-induced SP-A oxidation by plant polyphenols
(2007)
Surfactant protein-A (SP-A) is the best studied and most abundant of the protein components of lung surfactant and plays an important role in host defense of the lung. It has been shown that ozone-induced oxidation of SP-A ...
Cytogenetic effects of grape extracts (Vitis vinifera) and polyphenols on mitomycin C-induced sister chromatid exchanges (SCEs) in human blood lymphocytes
(2007)
In the present study, the effects of extracts and polyphenol-rich fractions as well as monomer polyphenols identified in them, from both red and white grapes, on mitomycin C (MMC) induced sister chromatid exchanges (SCEs) ...
Assessment of antioxidant/anticarcinogenic activity of plant extracts by a combination of molecular methods
(2005)
Cancer chemoprevention is considered to be a promising approach for cancer control, as it has been identified by both epidemiological and molecular studies that environmental factors are the major causes of cancer. ...
Assessment of antioxidant activity of extracts from unique Greek varieties of Leguminosae plants using in vitro assays
(2007)
Background: It is believed that legumes are a very good source of micronutrients and phytochemicals that present chemopreventive activity against diseases such as diabetes, coronary heart disease and colon cancer. Methanolic ...
Activity of grape extracts from Greek varieties of Vitis vinifera against mutagenicity induced by bleomycin and hydrogen peroxide in Salmonella typhimurium strain TA102
(2006)
Several in vivo and in vitro studies have shown that grape extracts could prevent certain steps in carcinogenesis and a few mechanisms have been proposed for this activity. In this study, the potential antimutagenic activity ...
Plant phenolics protect from bleomycin-induced oxidative stress and mutagenicity in Salmonella typhimurium TA102
(2004)
Antioxidants are deemed to be important against DNA damage and mutations induced by reactive oxygen species (ROS). An assay for the ability of plant phenolics to protect against mutations caused by bleomycin treatment in ...
Effects of plant phenolics and grape extracts from Greek varieties of Vitis vinifera on Mitomycin C and topoisomerase I-induced nicking of DNA
(2005)
In recent years, a number of reports have shown the anticancer activity of grape extracts and wine against various types of cancer such as breast, lung and gastric cancer. This property is mainly attributed to the plant ...
