Background: Oxidative stress and decreased antioxidant levels have been projected as a potential factors involved in the pathophysiology of diverse male infertility types, including asthenospermia. The generation of reactive oxygen species (ROS) in the male reproductive tract has become an actual concern because of their probable noxious effects, at high levels, on physical properties of sperm ...

to study the effects of phosphate and zinc sulfate fertilizers application methods on the yield and yield components of maize under water stress a randomized complete block with split plot factorial arrangement with three replications at research farm of the bu ali sina university was conducted in 2014. three levels of irrigation after 60, 90 and 120 mm evaporation from evaporation a pan was as...

ZnO nanoparticles were synthesized by a microwave-assisted chemical method. ZnO nanostructures were synthesized via a fast reaction between zinc acetate and ammonia at presence citric acid and other effective agents in chemical procedure. Nanostructures were characterized by X-ray diffraction , scanning electron microscopy. Seed yield and seed quality of safflower grown under drought stress. Th...

in order to study the effect of  foliar application of zinc and iron on germination of soybaen seed under different level of irrigation, an experiment was conducted in 2009 at shahrekord agricultural research center. main factor was including of four levels of drought stress as irrigation (irrigation after 60, 80, 100 and 120 mm evaporation from class a evaporation basin) and sub factor was inc...

We investigated the effects of Heterodera glycines cyst components and surface disinfestants on hatching of H. glycines eggs in vitro. Eggs were incubated in either H. glycines cyst wall fragments, cyst wall and egg rinsate, egg homogenate, or control solutions of soybean root diffusate, sterile distilled water, or zinc sulfate. Hatch in cyst wall and egg rinsate, and egg homogenate, was greate...

BACKGROUND The most commonly used medications for attention deficit hyperactivity disorder (ADHD) are the psychostimulants. There is, however, considerable awareness in alternative, nonstimulant therapies, because some patients respond poorly to stimulants or are unable to tolerate them. Some studies suggest that deficiency of zinc play a substantial role in the aetiopathogenesis of ADHD. There...
