the purpose of this study was to evaluate the probable effects of leptin addition in different levels to the semen extender on sperm quality (motility and motility parameters, viability, sperm membrane integrity, and dna damage). semen specimens were evaluated immediately after leptin addition, equilibration time and after thawing the frozen semen. five healthy buffalo bulls (5 ejaculates from ...

Frozen-thawed semen from six Boer bucks was pooled and used to compare the recently available commercial product CapriPure with Percoll for sperm quality. Sperm quality parameters such as sperm motility, concentration, membrane integrity (PI/CFDA), acrosome integrity (FITC-PNA) and mitochondrial activity (JC-1) were evaluated before and after sperm processing using CapriPure and Percoll density...

BACKGROUND Ketamine, an injectable anesthetic in human and animal medicine, is also a recreational drug used by young adults. The aim of this study is to evaluate the effects of ketamine on membrane integrity, DNA fragmentation and sperm parameters in humans. MATERIALS AND METHODS This prospective study was conducted on 40 males with normal semen samples over one month (August 2012). Subjects...

For artificial insemination (AI) in pigs, preservation of liquid boar semen at 16-20 degrees C is still common practice as sperm cryopreservation remains suboptimal in this species. To meet the different needs of the swine industry, several extenders have been developed to preserve semen in liquid form for short--and long-term storage. In the present study, three different commercial extenders ...

Extensive efforts are exerted looking for safe and effective chemotherapy for hepatocellular carcinoma (HCC). Specific and sensitive early biomarkers for HCC still in query. Present work to study proteolytic activity and lysosomal membrane integrity by hepatocarcinogen, trichloroacetic acid (TCA), in Wistar rats against aqueous olive leaf extract (AOLE).TCA showed neoplastic changes as oval- or...

Abstract To understand the mechanism governing postharvest senescence of Zizania latifolia (Z. latifolia), and regulatory induced by 1-methylcyclopropene (1-MCP) during storage at 25 °C, physiobiochemical conjoint analyses transcriptome metabolome were performed. The results indicated that 1-MCP treatment engendered changes in expression genes metabolites Z. latifolia. maintained a good visual ...

We examined the relationship between integrity of cumulus cells and nuclear maturation rate after in vitro culture to determine a non-invasive prediction of the maturational competence of feline oocytes. Feline cumulus-oocyte complexes (COCs) were collected from either small (400-800 μm) or large (≥800 μm) follicles. Immediately after collection, cumulus cells were evaluated morphologically (th...

Objective(s):Isoprenoid biosynthesis is a key metabolic pathway to produce a wide variety of biomolecules such as cholesterol and carotenoids, which target cell membranes. On the other hand, it has been reported that statins known as inhibitors of isoprenoid biosynthesis and cholesterol lowering agents, may have a direct antimicrobial effect on the some bacteria. The exact action of statins in ...

Duodenal and jejunal brush border membrane vesicle integrity was studied after in vitro treatment of rabbit tissue with ethyl, benzyl or octyl alcohol. The effects of the alcohols on gastric parietal cell apical and microsomal membrane vesicle integrity was also studied. Membrane vesicle integrity was determined from the enclosed volume of the vesicle preparations, measured as [14C]glucose spac...
