Deoxynivalenol reduces quality parameters and increases DNA damage in mice spermatozoa.

This study was performed to investigate in vitro effects of deoxynivalenol (DON) on mice sperm quality parameters including viability, motility and DNA damages at various concentrations and exposure times. Mice spermatozoa were exposed to DON at 0, 2.5, 5 and 10 µM for 1, 3 and 6 hr, motility parameters were evaluated by computer-assisted analysis and viability was examined by colorimetric metabolic activity assay and HOS test.

Prevalence and molecular characterization of staphylococci isolated from sheep with subclinical mastitis in West-Azerbaijan province, Iran.

This study was conducted to investigate the prevalence of subclinical mastitis caused by Staphylococcus spp. in ewes in West-Azerbaijan province of Iran. Molecular characterization of isolated Staphylococcus spp.

Effects of diluting medium and holding time on sperm motility analysis by CASA in ram.

The aim of this study was to evaluate the effects of dilution rate and holding time on various motility parameters using computer-assisted sperm analysis (CASA). The semen samples were collected from three Ghezel rams. Samples were diluted in seminal plasma (SP), phosphate-buffered saline (PBS) containing 1% bovine serum albumin (BSA) and Bioexcell.
