Several gene expressions are related to the success of spermatogenesis. Protamine plays an important role in sperm DNA packaging, spermatogenesis, and quality. This study aimed isolate RNA from spermatozoa determine expression profiles protamine 1 (PRM1) 2 (PRM2). Six Pasundan bulls aged 5-8 years with a body weight 380 kg-430 kg were used for this study. The classified into group A (70%-79%) B...

PURPOSE Vitis vinifera is a species of Vitis that is native to the Mediterranean region, central Europe, and southwestern Asia, and has been used as a drug in traditional medicine. Traditional medicinal plants have been used for medical purposes with increasing effectiveness. It is important to identify drugs that inhibit spermatogenesis. Therefore, the present study aimed to investigate the ef...

Background and aims: Corticotropin releasing hormone (CRH) is a major mediator of the stress response in the brain-gut axis. Irritable bowel syndrome (IBS) is presumed to be a disorder of the brain-gut link associated with an exaggerated response to stress. We hypothesised that peripheral administration of a-helical CRH (ahCRH), a non-selective CRH receptor antagonist, would improve gastrointes...

introduction: to evaluate the quick cryopreservation technique on parameters of motility, morphology, and vitality of spermatozoa from normozoospermic ejaculates. materials and methods: in this prospective study, a total of 37 normal ejaculates were evaluated according to who criteria, then each sample was divided into two aliquets and sample was cryopreserved with quick freezing method. sperm ...

in order to evaluate the effects of phenytoin on the reproductive system of rats in detail, 60 male rats were divided equally into 6 groups: 1-5 received 10 mg/kg/day phenytoin ip for 1,2,3,4 and 5 weeks, respectively. however, group 5 did not receive any phenytoin for the last 5th week. the control group (group 6) did not receive any treatment. the results revealed that phenytoin does not have...

The effects of intragastric infusion of 10% Intralipid and 10% dextrose on the intraluminal pressures in the antrum, pylorus and duodenal bulb have been examined. Ten studies with each infusate have been performed in 10 normal subjects and the results compared with those obtained previously in 22 studies during intragastric infusion of isotonic saline. During saline infusion, contractile activi...

Understanding flow and transport of bacteria in porous media is crucial to technologies such as bioremediation, biomineralization or enhanced oil recovery. While physicochemical filtration well-documented, recent studies showed that bacterial motility plays a key role the process. Flow experiments performed microfluidic chips containing randomly placed obstacles confirmed distributions non-moti...

The present study investigated the existing relationship between computer assisted semen motility parameters and gametes motility duration, known to express semen quality and fertilizing capacity in fish. The objective was particularly to identify computer aided semen analysis (CASA) parameters that could be used as potential fertility predictors. Semen samples were collected from the beginning...
