background: the role of attenuation in antioxidant capacity or expansion of pro-oxidant/oxidant is well known for the development of stress oxidative. the aim of this study was to evaluate the plasma antioxidant capacity along with uric acid in patients with diabetic nephropathy (dn+) and without diabetic nephropathy (dn-). materials and methods: the research population included 88 patients wit...

PURPOSE To determine the activity of seminal plasma catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPX) and their relationship with malondialdehyde (MDA), as a marker of lipid peroxidation, content of spermatozoa and seminal plasma in normozoospermic and asthenozoospermic males. MATERIALS AND METHODS Semen samples were obtained from 15 normozoospermic and 30 asthenozoo...

several lichen species have been used for medicinal purposes throughout the ages, and they were reported to be effective in the treatment of different disorders including tuberculosis, hemorrhoids, ulcer, dysentery and cancer. it is revealed that they may be easily accessible sources of natural drugs that could be used as a possible food supplement or in pharmaceutical industry after their safe...

BACKGROUND Epidemiologic studies suggest that high flavonoid intake confers a benefit on cardiovascular outcome. Endothelial function, arterial stiffness, and wave reflections are important determinants of cardiovascular performance and are predictors of cardiovascular risk. METHODS The effect of flavonoid-rich dark chocolate (100 g) on endothelial function, aortic stiffness, wave reflections...

BACKGROUND Semen analysis is the cornerstone in the evaluation of male (in)fertility. However, there are men with normal semen tests but with impaired fertilizing ability, as well as fertile men with poor sperm characteristics. Thus, there is rising interest to find novel parameters that will help to predict and define the functional capacity of spermatozoa. METHODS We examined whether there ...

This study aimed to analyze seasonal variations in the antioxidant defence systems of the seminal plasma and fluids of the cauda epididymis and vesicular glands of the boar. The analyzed antioxidants included superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and total L-glutathione (GSH+GSSG). Seasonal changes in total protein content and total antioxidant status (TAS) of...

An ovulation-inducing factor (OIF) in the seminal plasma of llamas and alpacas (induced ovulators) and cattle (spontaneous ovulators) suggests that OIF is a conserved constituent of seminal plasma among mammals. In this study, three experiments were designed to determine the biological effects of OIF in different species. In experiment 1, superstimulated prepubertal female CD-1 mice (n=36 per g...

Lipids are the main structural/functional components of the sperm, and their composition may undergo a series of modifications in relation to either physiologic events and/or diet. The effect of lecithin supplementation on reproductive and reproductive performance were studied in rabbits bucks. Twenty eight adult V line rabbits (at age between 7-8 months) were divided into four equal groups. Th...

Experiments have been reported in Paper I (1) in which the proteins of bovine seminal plasma were subjected to preliminary and electrophoretic characterization. In order to characterize this protein system further, ultracentrifugal and immunological methods have been applied. A limited amount of work has been reported on the ultracentrifugation of the seminal plasma proteins. Ross (2) has noted...
