Enzymatic conversion of dihydrotestosterone from 3-keto to 3-enol form in the rat prostate
(1996)
Dihydrotestosterone (DHT) is the active androgen, as well as a strong tumor promoter in the prostate, where several enzymes are essential for the regulation of its activity. We localized four enzymes promoting the enolization ...
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 ...
Acute effects of electronic and tobacco cigarette smoking on complete blood count
(2012)
The World Health Organisation called for research assessing the safety of electronic cigarette (e-cigarette). We evaluated the acute effect of active and passive e-cigarette and tobacco cigarette smoking on complete blood ...
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. ...
Sampling time is crucial for measurement of aerobic exercise-induced oxidative stress
(2007)
Purpose: To thoroughly investigate the time-course changes of several commonly used markers of oxidative stress by performing serial measurements during a 24-h period after an acute bout of strenuous cardiovascular exercise. ...
Effects of xanthine oxidase inhibition on oxidative stress and swimming performance in rats
(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 ...
Antioxidant activity of a series of fluorinated pyrano-nucleoside analogues of N-4-benzoyl cytosine and N-6-benzoyl adenine
(2007)
Fluorinated nucleoside analogues are known as antitumor, antiviral and chemotherapeutic agents, although the antioxidant activity of this kind of molecules is not yet investigated. In this study we have tested the antioxidant ...
Elimination profiles of flurbiprofen and its metabolites in equine urine for doping analysis
(2001)
Flurbiprofen and its main acidic metabolites were detected in equine urine after a single-dose administration of 500 mg flurbiprofen to two 2.5-3.5-years-old mares, in order to be used in equine doping control routine ...
Effects of plant phenolics and grape extracts from Greek varieties of Vitis vinifera on Mitomycin C and topoisomerase I-induced nicking of DNA
(2005)
In recent years, a number of reports have shown the anticancer activity of grape extracts and wine against various types of cancer such as breast, lung and gastric cancer. This property is mainly attributed to the plant ...
Anti-inflammatory effects of a special carbohydrate-whey protein cake after exhaustive cycling in humans
(2013)
Intense exercise induces increased levels of pro-inflammatory and anti-inflammatory cytokines. Thus, the purpose of this study was to examine the effects of a special cake (consisting of carbohydrate to whey protein 3.5:1) ...
