Background: Advances in nanotechnology have permitted molecular-based targeting of cells through safe and biocompatible magnetic nanoparticles(MNP). Their use to detect and remove damaged spermatozoa from semen doses ...
Objective:To predict the protein similarity, biological function and structure of 116 kDa protein that was isolated from human sperm membrane of acrosome by usingin silico. Methods:Predictions for 116 kDa protein simi...
Objective:To determine the effects of different concentrations of penicillamine, hypotaurine, and epinephrine (PHE) as well as incubation time on motility, hyperactivity and acrosome reaction (AR) of ram spermin vitro...
