The relationship between oxidative stress and some exercise components of resistance exercise (e.g. intensity, exercise volume) has not been clearly defined. Additionally, the oxidative stress markers may respond differently in various conditions. This study aims to determine the effects of progressive intensity of resistance exercise (RE) on oxidative stress and antioxidants in trained and unt...

Changes in plasma endogenous and dietary antioxidants and oxidative stress markers were studied following two 90 min elite female soccer games separated by 72 h of either active or passive recovery. The active recovery group (n 8) trained for 1 h at 22 and 46 h after the first game (low-intensity cycling and resistance training), while the passive group rested (n 8). Blood samples were taken be...

OBJECTIVES Several oxidants and antioxidants have been evaluated in schizophrenia. However, previous studies frequently focused on individual parameters. Determination of the total oxidant and antioxidant status may be more useful. Therefore, we aimed to evaluate both plasma total oxidant status (TOS) and total antioxidant status (TAS) together with the oxidative stress index (OSI) in schizophr...

The accurate assessment of oxidative stress in biological systems is a problem for all investigators working on the role of free radical damage in disease. Numerous assays have been described to measure various free radical damage products or antioxidant status, and the plethora of available techniques attests to the fact that no ideal method is available. The concept of a single test that migh...

Aim: Reactive oxygen species induce oxidative stress that may contribute to endothelial dysfunction. In addition to endogen antioxidants, adding antioxidants to diet has been used to reduce oxidative-stress-induced endothelial dysfunction. Resveratrol is a natural phytoalexin which has many eff ects including antioxidant activity. Th e aim of this study was to investigate whether resveratrol co...

OBJECTIVES To observe if there is any connectivity between oxidative stress and cardiovascular diseases (CVDs). MATERIALS AND METHODS Patients suffering from different cardiovascular diseases (hypertension, ischemic heart disease, rheumatic heart disease) attending Manipal Teaching Hospital, Pokhara and strictly matched controls were selected for this study. Oxidative stress (OS) was measured...

BACKGROUND: Osteoporosis is a condition of reduced bone mineral density (BMD) which leads to increased bone fragility and a marked increase in the risk of fractures. Postmenopausal osteoporosis affects women from one to twenty years after menopause. During these years, menopausal hormonal changes cause alterations in the serum levels of various biochemicals which reflect the bone losses. OBJECT...

OBJECTIVE The aim of the present study was to investigate influence of oxidative stress on newborn organism, in terms of the dynamics of malondialdehyde (MDA) concentration changes and of the activities of selected antioxidants in asphyxial newborns on the 1st and 5th day of life. METHOD In the group of 62 preterm and term asphyxial newborns, characterized by the presence of asphyxial criteri...

BACKGROUND Fruits and vegetables, foods rich in flavonoids and antioxidants, have been associated with lower risk of stroke, coronary heart disease, and markers of inflammation and oxidative stress in adults. Markers of inflammation and oxidative stress are predictors of coronary heart disease risk; however, it is unknown whether these markers are related to dietary flavonoid and antioxidant in...
