We examined in vitro antioxidant capacity of polyphenolic extract obtained from the wood of oak Quercus robur (QR), Robuvit, using TEAC (Trolox equivalent antioxidant capacity) method and the effect of its intake on markers of oxidative stress, activity of antioxidant enzymes, and total antioxidant capacity in plasma of 20 healthy volunteers. Markers of(More)
The increase in the detection rate for premalignant changes of bronchial epithelium was studied in 56 symptom-free volunteers from the risk group of Czech uranium miners (mean age 50.69 years, mean WLM 21.06 (1 Working Level Month is equal to the absorption of latent energy of 2.08 x 10(-5) J/m(3) in one month, i.e. 170 working hours)) by the additional(More)
This study investigated the contribution of blood oxidative stress (OS) to the development of hypertension, as well as sex differences in the antioxidant defense system (ADS) in genetic models of hypertension. Nine-week-old normotensive Wistar-Kyoto (WKY) rats, borderline hypertensive rats (BHR) and spontaneously hypertensive rats (SHR) of both sexes were(More)
Considering the massive increase of computer tomography (CT) examinations in Slovakia during the last 10 y, it can be expected that a higher radiation load may be observed in the Slovak population. Since child population is more sensitive to radiation than adult population, a monitoring has started to see how high the radiation dose is for paediatric(More)
Erythrocyte deformability is an important property of erythrocytes that considerably affects blood flow and hemodynamics. The high content of polyphenols present in dark chocolate has been reported to play a protective role in functionality of erythrocytes. We hypothesized that chocolate might influence erythrocytes not only after repeated chronic intake,(More)
The Slovak government organizes the radiation protection policy through its regulatory authorities within the Ministry of Health, on a central level. The health protection regulations are compatible with international standards and recommendations of the ICRP and the EC. The general requirements on quality assurance (QA) and quality control (QC)(More)
Background Multiple sclerosis (MS) is an autoimmune disease of central nervous system, which unknown etiology, but recent studies suggest important role of oxidative stress in its pathogenesis. The aim of our study was to analyze various markers of oxidative and nitrative damage, their mutual correlations and correlations with the state of the bloodbrain(More)
