objective: cigarette is a rich source of oxidants and reactive nitrogen species. nitric oxide (no) in high concentration has deleterious effects on human sperm function. antioxidant defense system in seminal plasma protects spermatozoa from the attack of reactive oxygen metabolites. the purpose of this study was to determine the correlation between cigarette smoking with the no levels and the t...

in this paper, thermal effect of plasma arc welding is investigated, and temperature field of ferrite stainless steel is acquired. thermal effect of plasma arc and subsequently the generated temperature field in the work piece is the key for analysis and optimization of this welding process, which is the main goal of this paper. finite element simulation of welding process by simplec method and...

conclusions it seems that in people with type 2 diabetes, acute aerobic exercise can decrease the plasma levels of glucose, possibly through increasing orexin a. in addition, negative energy balance is necessary to decrease the levels of insulin and insulin resistance during acute aerobic exercise. results the analysis of findings in p ≤ 0.05 indicated that acute aerobic exercise caused a signi...

conclusions lead contamination in the presence of an emf exacerbates the oxidative damage to plasma proteins as well as the conformational changes in hb. an artificial neural network can be used as a predictive tool for the oxidative danger posed to workers in industrial fields, battery manufacturing companies, and power plants. patients and methods in this experimental study, the blood samples...

Low plasma level of vitamin D is linked to the increased risk of cardiovascular diseases such as hypertension, diabetes, dyslipidemia and peripheral vascular diseases. Vitamin D deficiency is a worldwide problem that involves Iranian population. To the best of our knowledge, this was the first investigation on venous thromboembolism (VTE) subjects that assessed the correlation of vitamin D leve...

A rapid and sensitive HPLC method was developed for determination of losartan in plasma. Losartan was extracted from plasma by a two-step extraction procedure using chloroform as extracting solvent in acidic medium. HPLC analysis was performed on a cyano reversed-phase column using phosphate buffer (pH 4.3), acetonitrile (750:250, v/v) as mobile phase with a flow rate of 0.9 mL/min. Sodium dicl...
