Connection between Telomerase Activity in PBMC and Markers of Inflammation and Endothelial Dysfunction in Patients with Metabolic Syndrome
(2012)Metabolic syndrome (MS) is a constellation of metabolic derangements associated with vascular endothelial dysfunction and oxidative stress and is widely regarded as an inflammatory condition, accompanied by an increased ... -
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 ... -
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) ... -
Decreased blood oxidative stress after repeated muscle-damaging exercise
(2007)Purpose: To examine the effect of repeated muscle-damaging exercise on the time-course changes in several indices of muscle damage, and to compare them with changes in blood oxidative stress indices. Methods: Twelve females ... -
Determination of xylazine and its metabolites by GC-MS in equine urine for doping analysis
(2004)Xylazine and its main metabolites were detected in equine urine after a single-dose intravenous administration of 0.98 and 1.01 mg/kg body weight xylazine, respectively, in two horses, in order to be used for equine doping ... -
Dexamethasone has a biphasic effect on the c-Jun m-RNA expression in the fetal and adult rat lung, in vivo
(1999)Glucocorticoids are a very potent therapy for the treatment of asthma as well for lung maturation in the prematurely newborn animals and human. It has been demonstrated that glucocorticoid receptors antagonize the actions ... -

Dietary administration of tannic acid lowers plasminogen activator activity in the liver of C3H hepatoma bearing male mice
(2000)Background: This study was undertaken to investigate if low-dose dietary administration of tannic acid exerts its chemopreventative activity on hepatocarcinogenesis in male C3H mice through changes of plasminogen activator ... -
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 ... -
Differential display of m-RNAs in fish gonads by modified DD-PCR
(2002)In a previous report we presented a modification of the original Differential Display PCR technique using a single oligo (dT) primer for the reverse transcription reaction (instead of the various oligo (dT)NM primers that ... -
Differential effects of xanthine oxidase inhibition and exercise on albumin concentration in rat tissues
(2010)Albumin is a protein present in almost all kinds of mammalian cells. It has binding sites for several molecules, and possesses antioxidant and other important properties. The aim of this study was to examine the effects ... -
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 ... -
The effect of allopurinol on protein carbonyls and swimming performance in rats
(2008)Allopurinol is an inhibitor of xanthine oxidase. Xanthine oxidase is a major contributor of free radicals during exercise. Previous studies have shown that free radicals are vital for physiological adaptations in exercise. ... -
The effect of exercise-induced hypoxemia on blood redox status in well-trained rowers
(2012)Exercise-induced arterial hypoxemia (EIAH), characterized by decline in arterial oxyhemoglobin saturation (SaO(2)), is a common phenomenon in endurance athletes. Acute intensive exercise is associated with the generation ... -
Effect of Leguminosae family plant extracts and polyphenolic fractions on topoisomerase I-induced nicking of DNA
(2008)Topoisomerase I constitutes one of the enzymes playing crucial role in replication, transcription, recombination, chromosome condensation and maintenance of genome stability. Because it is an essential enzyme for vital ... -
The effect of muscle-damaging exercise on blood and skeletal muscle oxidative stress: Magnitude and time-course considerations
(2008)The aim of this article is to present the effects of acute muscle-damaging exercise on oxidative stress/damage of animal and human tissues using a quantitative approach and focusing on the time-course of exercise effects. ... -
The effects of a single bout of exercise on resting energy expenditure and respiratory exchange ratio
(2004)We investigated the effects of a single bout of aerobic and resistance exercise of similar relative intensity and duration on resting energy expenditure (REE) and substrate utilisation. Ten young healthy males volunteered ... -
