Oxidative stress plays a key role in the pathophysiological process of uremia and its complications, particularly in cardiovascular disease. The level of oxidative stress markers is known to increase as chronic kidney disease progresses and correlates significantly with the level of renal function. Hemodialysis and peritoneal dialysis are major modes of renal replacement therapy for end-stage r...

Background and Aims: Decreased sperm motility and increased level of oxidative stress are major causes of male infertility. This study was designed to evaluate the effect of propolis supplementation on spermatogram and reproductive hormones in asthenozoospermic men. Materials and Methods: In this randomized, double-blind controlled clinical trial, 60 asthenozoospermic men attending an inferti...

trenuous physical exercise is thought to stimulate increased production of reactive oxygen species (ROS), as demonstrated by elevated markers of oxidative stress in the skeletal muscle, blood, and urine of athletes. Antioxidant supplementation has been shown to reduce levels of such markers, and as such, holds promise for limiting exercise-induced oxidative damage, reducing the rate of muscle f...

Background and Aim: Reduction in sperm motility is one of the main causes of male infertility. The aim of this study was to investigate the effect of Carob supplementation on sperm parameters, inflammatory factors, oxidative stress indices and sex hormones in the men with idiopathic infertility. Materials and Methods: This study was a randomized double-blind controlled clinical trial which inc...

Maternal cigarette smoke exposure (SE) causes detrimental changes associated with the development of chronic neurological diseases in the offspring as a result of oxidative mitochondrial damage. Maternal L-Carnitine administration has been shown to reduce renal oxidative stress in SE offspring, but its effect in the brain is unknown. Here, we investigated the effects of maternal L-Carnitine sup...

Investment in reproduction is costly and frequently decreases survival or future reproductive success. However, the proximate underlying causes for this are largely unknown. Oxidative stress has been suggested as a cost of reproduction and several studies have demonstrated changes in antioxidants with reproductive investment. Here, we test whether oxidative stress is a consequence of reproducti...

Background Recent studies have suggested the importance of oxidant/antioxidant status in initiation and progression of breast cancer. The aim of this study was to evaluate oxidative stress markers in breast cancer patients before and after 3 cycles of chemotherapy with adriamycin and cytoxan (AC). Also, in this study the effect of age and the stage of disease on oxidative stress markers were co...

Various circulating biochemical markers are indicators of pathological state in leukemia and its subtypes. Increased oxidative stress and decreased antioxidant factors portray clear image associated with malignancies during subtypes of leukemia. In this research work we investigated the inter-relationship among the subtypes of leukemia with circulating biochemical markers and oxidative stress i...

Oxidative stress negatively affects folliculogenesis and embryo development. However, a reliable and biologically accurate indicator of oxidative stress does not yet exist. On these bases, the aim of this study was to assess -and compareblood and follicular fluid (FF) redox status in 45 infertile subjects (and 45 age-matched controls) undergoing in vitro fertilization (IVF) and to establish its...
