Reactive oxygen species are crucial to normal biological processes; they are potentially dangerous and are commonly referred to as prooxidants. The reactive oxygen intermediates can cause direct cellu...
Background: Sperm dysfunction caused by reactive oxygen species (ROSs) is one of the major causes of infertility in men, which leads to, lipid peroxidation (LPO) and the formation of stable peroxidati...
Background: High cholesterol levels have long been considered an independent risk factor for cardiovascular disease (CVD).
To evaluate the effects of alendronate (ALN) and risedronate (RIS), which are agents for preventing and treating postmenopausal osteoporosis, on hepatic antioxidant enzyme activity and lipid peroxidat...
The changes in the serum sialic acid levels, total lipid peroxidation products (MDA), and glutathione reductase activity were estimated in patients with rheumatoid arthritis. Serum Sialic acid is know...
Background: a variety of studies have noted seasonal variation in blood lipid levels, yet the mechanism for this phenomenon has not been clear. This leads to significant difference in prevalence of li...
Iron is a pro-oxidant cofactor that may be linked to atherosclerosis progression. Free iron catalyzes the generation of free radicals and free radicals promote the oxidation of lipids. Reduction of bo...
Background: Obesity is associated with increased lipid peroxidation. It has also been suggested that risk of lipid peroxida­tion increases with increasing body iron stores. The aim of this study w...
Renal ischemia-reperfusion (IR) injury is a common problem in kidney transplantation. There is increasing evidence about the role of the reactive oxygen species (ROS) in these injuries and endogenous ...
It has been maintained that free oxygen radicals (FOR) that occur in cell have important roles in the ethiopathogenesis of diabet, and that cell damage progressing as a result of their accumulation is...
15 healthy sedentary men, 19-25 years old an did not have any programmed physical activity, were studied. The subjects were asked to run submaximal 15-20 min every day for 5 weeks. Erythrocyte lipid p...
The aims of this study were to determine the degree of lipid peroxidation in the sera of postmenopausal women and compare this with the lipid peroxidation of a premenopausal group, and to see if there...
To examine the effects of increased O 2 utilization on blood antioxidant status and lipid peroxidation, ten trained male athletes took part in a 20 km distance race. Venous blood samples were removed ...
Recent few studies revealed that increased levels of oxygen free radicals might play a role in tissue damage. There are some studies in the literature proposing that increased levels of oxygen radical...
This study was carried out in order to determine the effects of levonorgestrel (LNG) and progestin derivatives, alone and in combination with melatonin (MEL), on the plasma oxidant-antioxidant system,...
