Purpose : Plant nitrogen use efficiency can be increased by improving N uptake (NUpE). Root system architecture of the plant plays a vital role in uptaking water and nutrients including N. The present study was conducted to compare root architectural traits different wheat species at early seedling development vegetative growth stage while mature stages under controlled environment.Research Met...

background: glycosidases profusion in male reproductive fluids suggests a possible relationship with sperm function. although hexosaminidase (hex) is the most active glycosidase in epididymal fluid and seminal plasma, as well as in spermatozoa, glucosidase is considered a marker for epididymal function and azoospermia. objective: the aim of this study was to determine hex activity in seminal pl...

Background: The lipid peroxides and their degradation products are highly toxic to spermatozoa and may play a major role in sperm dysfunction. The purpose of this study was to determine the level of lipid peroxidation as indicated by malondialdehyde (MDA) in the spermatozoa and seminal plasma of asthenozoospermic and normozoospermic males. In addition, correlation of lipid peroxidation with mot...

the environmental pollution is one of the factors contributing to the decrease of sperm quality for human beings. the aim of this study was to assess cadmium (cd), chromium (cr), and copper (cu) concentration of man in environmental pollution site, and explore relationships between men exposure to cd, cr, and cu and semen-quality parameters in environmental pollution site.ninety five men were r...

Objective The lipid composition of a mammal’s spermatozoa and seminal plasma vary in both structure and function. Evidence exists to suggest that dietary supplementation with the appropriate polyunsaturated fatty acids (PUFAs) affects spermatogenesis, semen quality and sperm motility. Therefore, this study has been conducted to evaluate the correlations between serum lipid profile and histologi...
