AIM The purpose was to determine the changes of oxidative stress and antioxidant markers in plasma after repeated bouts of supramaximal exercise and the effects of coenzyme Q10 supplementation on these changes. METHODS This randomized, double blind, crossover study was composed of two 8-week periods of supplementation with either 100 mg.day(-1) CoQ10 or placebo. Fifteen healthy and sedentary ...
Since the beginning of propolis research, several groups have studied its antibacterial, antifungal, and antiviral properties. However, most of these studies have only employed propolis ethanolic extract (PEE) leading to little knowledge about the biological activities of propolis water extract (PWE). Based on this, in a previous study, we demonstrated the anti-inflammatory and immunomodulatory...
