Biochemical and biological assessment of the inhibitory potency of extracts from vinification byproducts of Vitis vinifera extracts against glycogen phosphorylase
(2014)The inhibitory potency of thirteen polyphenolic extracts obtained from vinification byproducts of Greek varieties of Vitis vinifera against glycogen phosphorylase (GP) has been studied by kinetic experiments. GP is an ... -
Biological importance of reactive oxygen species in relation to difficulties of treating pathologies involving oxidative stress by exogenous antioxidants
(2013)Findings about involvement of reactive oxygen species (ROS) not only in defense processes, but also in a number of pathologies, stimulated discussion about their role in etiopathogenesis of various diseases. Yet questions ... -
Blood reflects tissue oxidative stress: a systematic review
(2015)We examined whether the levels of oxidative stress biomarkers measured in blood reflect the tissue redox status. Data from studies that measured redox biomarkers in blood, heart, liver, kidney and skeletal muscle were ... -
Cardiotoxicity in rabbits after a low-level exposure to diazinon, propoxur, and chlorpyrifos
(2014)Lethal cardiac complications leading to death and various arrhythmias have been reported after organophosphate and/or carbamate poisonings. The present study focuses on the long-term effects of repeated low-level exposure ... -
Chemoprevention of liver cancer by plant polyphenols
(2012)Primary liver cancer or hepatocellular carcinoma (HCC) is one of the most frequent tumors representing the fifth commonest malignancy worldwide and the third cause of mortality from cancer. Currently, the treatments for ... -
Comet assay: A brief history
(2009) -
Comparison of heavy metal concentrations in fish samples from three fish farms (Eastern Mediterranean) utilizing antifouling paints
(2015)Although aquaculture is considered the fastest growing food production industry, nevertheless there is little information regarding pollutant levels in cultured fish. Samples of cultured sea bass - Dicentrarchus labrax ... -
Contribution of aldehyde oxidase, xanthine oxidase, and aldehyde dehydrogenase on the oxidation of aromatic aldehydes
(2004)Aliphatic aldehydes have a high affinity toward aldehyde dehydrogenase activity but are relatively poor substrates of aldehyde oxidase and xanthine oxidase. In addition, the oxidation of xenobiotic-derived aromatic aldehydes ... -
Correlation of total polyphenolic content with antioxidant and antibacterial activity of 24 extracts from Greek domestic Lamiaceae species
(2012)Lamiaceae family species are considered important because of their use in folk medicine, culinary and flavouring throughout the world. Their interesting bioactivities are attributed mainly to essential oils, polyphenols ... -
Distribution and stability of aflatoxin M-1 during processing, ripening and storage of Telemes cheese
(2001)Telemes cheeses were produced using milk that was artificially-contaminated with aflatoxin M-1 at the levels of 0.050 and 0.100 mug/l. The cheeses produced in the two cheese-making trials were allowed to ripen for 2 months ... -
Distribution and stability of aflatoxin M-1 during production and storage of yoghurt
(2002)Yoghurt from cow's milk artificially contaminated with aflatoxin M-1 (AFM(1)) at levels of 0.050 and 0.100 g l(-1) was fermented to reach pHs 4.0 and 4.6. Yoghurt fermented to pH 4.6 was also used for preparing strained ... -
DNA damage and repair capacity in lymphocytes from obstructive sleep apnea patients
(2007)Obstructive sleep apnea (OSA) syndrome is a respiratory disease that is linked to heart attacks and high blood pressure. In the present study, we used the Comet assay to compare basal DNA damage and DNA damage induction ... -
Effect of a special carbohydrate-protein bar and tomato juice supplementation on oxidative stress markers and vascular endothelial dynamics in ultra-marathon runners
(2014)It is well established that exercise induces excessive production of reactive species leading to oxidative stress, which has been implicated in oxidative damage of macromolecules, immune dysfunction, muscle damage and ... -
Effect of a special carbohydrate-protein cake on oxidative stress markers after exhaustive cycling in humans
(2012)Exercise has been associated with oxidative stress that is correlated with muscle fatigue and reduced exercise performance. The aim of this study was to examine the effects of a special cake (consisting of carbohydrate to ... -
Effects of polyphenolic grape extract on the oxidative status of muscle and endothelial cells
(2014)A grape pomace extract enhanced antioxidant mechanisms in muscle and endothelial cells both in the absence and in the presence of oxidative stress-induced agent tert-butyl hydroperoxide (tBHP). In particular, muscle (C2C12) ...
