The Antioxidant Effects of a Polyphenol-Rich Grape Pomace Extract In Vitro Do Not Correspond In Vivo Using Exercise as an Oxidant Stimulus
Veskoukis, A. S.; Kyparos, A.; Nikolaidis, M. G.; Stagos, D.; Aligiannis, N.; Halabalaki, M.; Chronis, K.; Goutzourelas, N.; Skaltsounis, L.; Kouretas, D. (2012)Fruits, such as grapes, are essential food of the Mediterranean diet. Grape extracts have potent antioxidant and chemopreventive properties in vitro. Numerous studies have examined the effects of plant extract administration ... -
Blood reflects tissue oxidative stress depending on biomarker and tissue studied
Veskoukis, A. S.; Nikolaidis, M. G.; Kyparos, A.; Kouretas, D. (2009)This study investigated whether selected oxidative stress markers measured in blood adequately reflect redox status in skeletal muscle, heart, and liver. Several markers were determined after implementing two treatments ... -
Blood reflects tissue oxidative stress: a systematic review
Margaritelis, N. V.; Veskoukis, A. S.; Paschalis, V.; Vrabas, I. S.; Dipla, K.; Zafeiridis, A.; Kyparos, A.; Nikolaidis, M. G. (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 ... -
Dietary oxidative stress and antioxidant defense with an emphasis on plant extract administration
Veskoukis, A. S.; Tsatsakis, A. M.; Kouretas, D. (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 effects of xanthine oxidase inhibition and exercise on albumin concentration in rat tissues
Veskoukis, A. S.; Kyparos, A.; Stagos, D.; Kouretas, D. (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 ... -
The effect of allopurinol on protein carbonyls and swimming performance in rats
Veskoukis, A. S.; Nikolaidis, M. G.; Kyparos, A.; Kokkinos, D.; Varamenti, E.; Kouretas, D. (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. ... -
Effects of grape extracts on the in vitro activity of enzymes involved in oxidative stress regulation
Chrysoula, S.; Veskoukis, A. S.; Dimitrios, S.; Kalliopi, L.; Maria, A.; Haroutounian, S. A.; Maria, T.; Eleni, T.; Dimitrios, K. (2011)Background/Aim: A number of in vitro and in vivo studies have investigated the potential preventive activity of grape extracts against different diseases, and have mostly focused on their antioxidant properties. The present ... -
Effects of Greek legume plant extracts on xanthine oxidase, catalase and superoxide dismutase activities
Spanou, C. I.; Veskoukis, A. S.; Stagos, D.; Liadaki, K.; Aligiannis, N.; Angelis, A.; Skaltsounis, A. L.; Anastasiadi, M.; Haroutounian, S. A.; Kouretas, D. (2012)Legumes are considered to have beneficial health implications, which have been attributed to their phytochemical content. Polyphenols are considered the most important phytochemical compounds extensively studied for their ... -
Effects of xanthine oxidase inhibition on oxidative stress and swimming performance in rats
Veskoukis, A. S.; Nikolaidis, M. G.; Kyparos, A.; Kokkinos, D.; Nepka, C.; Barbanis, S.; Kouretas, D. (2008)The aim of this study was to examine the effect of allopurinol, a xanthine oxidase inhibitor, on oxidative stress and physical performance after swimming until exhaustion in rats. Blood and gastrocnemius muscle samples ... -
Flavonoid Glycosides Isolated from Unique Legume Plant Extracts as Novel Inhibitors of Xanthine Oxidase
Spanou, C.; Veskoukis, A. S.; Kerasioti, T.; Kontou, M.; Angelis, A.; Aligiannis, N.; Skaltsounis, A. L.; Kouretas, D. (2012)Legumes and the polyphenolic compounds present in them have gained a lot of interest due to their beneficial health implications. Dietary polyphenolic compounds, especially flavonoids, exert antioxidant properties and are ... -
GC-MS analysis of blood for the metabonomic investigation of the effects of physical exercise and allopurinol administration on rats
