chemical compositionMAMMALIAN sperm have been reported by various workers to contain no nucleoprotamine or nucleo-histone extractable by the usual means (with water or neutral salt solutions) 1 . This has been confirmed in the case of the bull, man, dog, boar and ram, but basic protein and ...
Chemical composition and protein source in the capacitation medium significantly affect the ability of human spermatozoa to undergo follicular fluid induced acrosome reaction. Hum Reprod 8:575-580.Calvo L, Dennison-Lagos L, Banks SM, et al: Chemical composition and protein source in the capa...
A chemical composition and vaginal sponge for introduction into the vaginal canal. The chemical composition has spermidicidal, bactericidal and virucidal activity, and when introduced into the vaginal canal, e.g. by a vaginal sponge, reduces or prevents the transmission of sexually transmitted ...
although many chemical components have been isolated and identified fromB. carterii, the toxicology and pharmacokinetic studies ofBoswellialong-term use are lacking. Some review articles onB. carteriihave been published, mainly concerning its chemical composition and...
97, though evidence that this occurs also remains limited108. Unfortunately, a poor understanding of the specific chemical structures of chemical signals in most animals limits broad inferences about the link between their molecular composition and the mechanisms of sexual selection that act upon them...
The influences of genotype or crop year on the nutritional and antioxidant properties of Oregon hazelnut skins have scarcely been studied. Therefore, the objectives of this study were to investigate the nutritional composition of hazelnut skins and kernels for four prominent Oregon cultivars (Barcelona,...
Major topics include the sex pheromones of gastropods, salamanders and a giant tree frog, and the conspecific attraction of sperm to ova of some of the organisms and animals described in this review.关键词: Biodegradation Defluorogenase Environmental toxicity Fluorinase Human health Perfluorinated ...
Lions (Panthera leo) use chemical signaling to indicate health, reproductive status, and territorial ownership. To date, no study has reported on both scent and composition of marking fluid (MF) from P. leo. The objectives of this study were to: 1) devel

. The impact of pollution (including at the individual level on the accumulation of Cu, Zn, Pb, and Cd in the liver) was assessed for indicators characterizing the quality of sperm from different aspects: morphology (proportion of cells with head and tail defects), motility (proportion of ...
