BACKGROUND: The active oxygen species, despite the damaging effects they have useful roles in the body are living things. OBJECTIVES: This research was done to determine whether Reactive Oxygen Species (ROS) could mediate Cyanide and Methylviologen signal in seed dormancy alleviation and sunflower seed germination, more widely, to assess their putative ro...

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 ...

Seed storage proteins are synthesized as sources of carbon, nitrogen and sulfur for the next generation of plants. Reactive oxygen species serve as second messengers for signal transduction; however, molecular targets of oxidant signaling have not been defined. Here, many researchers showes that ligand–receptor mediated signaling promotes reactive oxygen species– dependent protein carbonylation...

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...

background: it is proved that testis is sensitive to electromagnetic field (emf) and its damage results in infertility. exposure to emf induces reactive oxygen species production and affects on anti-oxidants defense mechanisms. metallothionein (mt) is a name for a group of low molecular weight (6-7 kda), sulfhydryl rich proteins. expression of mt1 and mt2 genes in testis tissue after emf exposu...

reactive oxygen species (ros) are produced in many normal and abnormal processes in humans, including atheroma, asthma, joint diseases, cancer, and aging. basal levels of ros production  in  cells  could  be  related  to  several  physiological functions  including  cell proliferation, apoptosis and homeostasis. however, excessive ros production above basal levels would impair and oxidize dna, ...
