conclusions our results show that oxidative stress could play an important role in male infertility as well as in sperm motility and sperm morphology. patients and methods this case control study was conducted using 35 men with idiopathic infertility and 34 men with proven fertility. seminal plasma tac and mda were measured by ferric reducing ability of plasma (frap) and thiobarbituric acid (tb...

the naturally occurring antioxidants: vitamin e, β-carotene and vitamin c are known to ameliorate theoxidative stress generated during various physiological and pathological conditions. the oxidative stress mayoccur at different sites, different times, and by different mechanisms in the animal system. lower levels ofthe anti-oxidant vitamins are associated with poor fertility and production lev...

Objective: Oxidative stress that damages proteins result in aging and age related diseases. The aim of this study is to determine the effect of tocotrienol rich fraction (TRF) on the expression of proteins in oxidative stress-induced caenohabditis elegans (C.elegans) which has homologous genes to humans. Methods: The worms were treated with TRF prior to, after and continuously in separate group...

conclusions despite the presence of vast oxidative stress in hepatitis b, antioxidant therapy is not always effective as a treatment strategy, especially considering that antioxidants can act as “double-edged swords” or antioxidants; if not used at the right time or place or in the right combination, these substances can easily become pro-oxidants. therefore, several studies will be needed to d...

background: infertility is defined as the inability to achieve the pregnancy within a year of unprotected intercourse. infertility is a complex issue and different factors such as stress oxidative can be involved in this problem. so, any attempt to neutralize oxidative stress would be helpful in the treatment of infertility. melatonin is a known scavenger of free radicals. objective: the aim of...

resistance exercise is associated with increased oxidative stress. however, it is not completely obvious how resistance training intensity can affect the rest levels of oxidative stress indexes. therefore, the aim of the present research was to study the effect of moderate resistance (mr) and high resistance (hr) training on oxidative stress. 20 males (age: 20.6±0.7 yr, height: 1.74±0.06 m, wei...
