Age-dependent changes in 8-oxoguanine-DNA glycosylase activity are modulated by adaptive responses to physical exercise in human skeletal muscle
(2011)8-Oxo-7,8-dihydroguanine (8-oxoG) accumulates in the genome over time and is believed to contribute to the development of aging characteristics of skeletal muscle and various aging-related diseases. Here, we show 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) ... -
Dietary oxidative stress and antioxidant defense with an emphasis on plant extract administration
(2012)Eukaryotic cells generally function in a reduced state, but an amount of reactive species is essential for several biochemical processes. The antioxidant network is the defensive mechanism that occurs when the concentration ... -
Lipid peroxidation and tissue damage
(1999)In recent years it has become apparent that the oxidation of lipids, or lipid peroxidation, is a crucial step in the pathogenesis of several disease states in adult and infant patients. Lipid peroxidation is a process ... -
No effect of antioxidant supplementation on muscle performance and blood redox status adaptations to eccentric training
(2011)Background: It was recently reported that antioxidant supplementation decreases training efficiency and prevents cellular adaptations to chronic exercise. Objective: This study aimed to investigate the effects of vitamin ... -
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 ... -
ROS-major mediators of extracellular matrix remodeling during tumor progression
(2013)Extracellular matrices (ECMs) represent a complex network of proteins, proteoglycans and glycosaminoglycans (GAGs), composed of independent structural domains, ultimately constituting the cell microenvironment. As a highly ... -
Stair Descending Exercise Using a Novel Automatic Escalator: Effects on Muscle Performance and Health-Related Parameters
(2013)A novel automatic escalator was designed, constructed and used in the present investigation. The aim of the present investigation was to compare the effect of two repeated sessions of stair descending versus stair ascending ...
