reactive oxygen species (ros)plays an important role in sperm motility. the physiological generation at low concentration induces beneficial effects on sperm functions and plays a significant role in sperm metabolism. meanwhile, the excessive generation of reactive oxygen species can overwhelm protective mechanism and triggers changes in lipid and protein layers of sperm plasma membrane, which ...

abstract background: at present study, acid modified banana leaf ash was used as an adsorbent for the successful removal of reactive black 5 (rb5) dye from aqueous environments. materials and methods: the effect of various operating parameters such as ph of solution, dye concentration, contact time, adsorbent dosage, and the temperature was investigated. results: maximum adsorption capacity of ...

results seminal plasma tac level in normospermic men was significantly higher than asthenoteratospermic men (p < 0.001) and oligasthenoteratospermic men (p < 0.001) and had posetive correlation with sperm count, motility and morphology. in contrast mda levels in normospermic men were significantly lower than in asthenoteratospermic men (p = 0.049) and oligoasthenoteratospermic men (p = 0.001) a...
