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 ...

Alzheimer's disease treated patients showed different patterns for oxidative stress and inflammation markers

Gubandru, M.; Margina, D.; Tsitsimpikou, C.; Goutzourelas, N.; Tsarouhas, K.; Ilie, M.; Tsatsakis, A. M.; Kouretas, D. (2013)

Alzheimer's disease (AD) is the most common type of dementia accounting for 60-80% of the reported cases. The aim of this study was to evaluate levels of certain parameters of oxidative stress and markers of endothelial ...

Nonlinear binding of sex steroids to albumin and sex hormone binding globulin

Zeginiadou, T.; Kolias, S.; Kouretas, D.; Antonoglou, O. (1997)

We have studied the binding of sex steroids to albumin and sex hormone binding globulin (SHBG) using gel filtration chromatography for the separation of the bound from the free fraction of the steroid. It was found that ...

Oxidative stress, inflammation and angiogenesis markers in elite female water polo athletes throughout a season

Varamenti, E. I.; Kyparos, A.; Veskoukis, A. S.; Bakou, M.; Kalaboka, S.; Jamurtas, A. Z.; Koutedakis, Y.; Kouretas, D. (2013)

Elite athletes undergo heavy training programs throughout the year. The aim of the present study was to evaluate blood biomarkers of redox status, oxidative stress, inflammation and angiogenesis over the course of a ...

Exercise-induced oxidative stress in G6PD-deficient individuals

Nikolaidis, M. G.; Jamurtas, A. Z.; Paschalis, V.; Kostaropoulos, I. A.; Kladi-Skandali, A.; Balamitsi, V.; Koutedakis, Y.; Kouretas, D. (2006)

Purpose: This study was designed to investigate whether individuals with glucose-6phosphate dehydrogenase (G6PD) deficiency can exercise without greater perturbations in their redox status compared with non-G6PD-deficient ...

Comparison of the blood redox status between long-distance and short-distance runners

Kostaropoulos, I. A.; Nikolaidis, M. G.; Jamurtas, A. Z.; Ikonomou, G. V.; Makrygiannis, V.; Papadopoulos, G.; Kouretas, D. (2006)

Exercise increases the production of reactive oxygen species, which may damage a number of cell constituents. Organisms have developed a sophisticated antioxidant system for protection against reactive oxygen species. Our ...

Decreased blood oxidative stress after repeated muscle-damaging exercise

Nikolaidis, M. G.; Paschalis, V.; Giakas, G.; Fatouros, A. G.; Koutedakis, Y.; Kouretas, D.; Jamurtas, A. Z. (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 ...

Acute exercise markedly increases blood oxidative stress in boys and girls

Nikolaidis, M. G.; Kyparos, A.; Hadziioannou, M.; Panou, N.; Samaras, L.; Jamurtas, A. Z.; Kouretas, D. (2007)

This study investigated the effect of an acute swimming protocol on selected blood redox status indices in trained children. Eleven boys and 11 girls (aged 9-11 y) swam 12 bouts of 50 m at a pace corresponding to 70%-75% ...

Gas chromatographic - Mass spectrometric cardiotonic glycosides detection in equine urine doping analysis

Kiousi, P.; Angelis, Y. S.; Koupparis, M.; Kouretas, D.; Diakakis, N.; Desiris, A.; Georgakopoulos, C. G. (2004)

A screening method for the detection of cardiotonic glycosides in horse's urine is presented in this paper. This method is based on the detection by gas chromatography-mass spectrometry (GC-MS) and gas chromatography-high ...

INCREASED OXIDATIVE STRESS BLOOD MARKERS IN WELL-TRAINED ROWERS FOLLOWING TWO THOUSAND-METER ROWING ERGOMETER RACE

Kyparos, A.; Vrabas, I. S.; Nikolaidis, M. G.; Riganas, C. S.; Kouretas, D. (2009)

Kyparos, A, Vrabas, IS, Nikolaidis, MG, Riganas, CS, and Kouretas, D. Increased oxidative stress blood markers in well-trained rowers following two thousand-meter rowing ergometer race. J Strength Cond Res 23(5): 1418-1426, ...
