The intensification of livestock production in response to the growing demand for animal products is increasingly creating new challenges terms control management and feeding, especially reproduction. Also, ewes are often considered responsible infertility problems a sheep flock, as reproductive capacity rams taken granted. However, it important have genetically superior males improve overall f...

AIM To ascertain whether caecal pH is different in patients with irritable bowel syndrome (IBS), whose primary symptoms are bloating and distension, to healthy controls. METHODS Motility and pH data were reviewed from 16 patients with Rome III defined IBS and 16 healthy controls, who had undergone a wireless motility capsule (WMC) study using a standardized protocol. Motility measures were an...

OBJECTIVES Reactive oxygen species (ROS) induced lipid peroxidation is associated with sperm function. Malondialdehyde (MDA) concentration and glutathione peroxidase (GPx) activity represent the lipid peroxidation and spermicidal antioxidant, respectively. We aimed to evaluate the relationship of MDA and GPx levels with sperm parameters. PATIENTS AND METHODS Specimens were divided into two gr...

This study was aimed at evaluating the in vitro effects of particulate matter (ranging from 2.5-10 m in an aerodynamic diameter, PM10) from an urban area on the motility of human spermatozoa. Samples of swim up selected human spermatozoa from three healthy men with normal semen parameters, according to WHO guidelines, were incubated for 4 hours with 10, 50 and 75 μg/ml of PM10. Kinetic paramete...

Varicocele is one of the most common causes of male infertility and spontaneous pregnancy rate after varicocelectomy is only about 30%. The most important seminal antioxidant is vitamin C but recent studies about the effects of vitamin C on spermatogenesis are controversial; therefore, we decided to evaluate its role after varicocelectomy. In a double blind randomized controlled clinical trial,...

background: women engaged with polycystic ovarian syndrome (pcos), as the commonest endocrine disorder, are known to have a specific type of adiposity. birth weight is among different contributors reported to be responsible for this diversity. objective: we aimed to compare the relation between birth weight and body fat mass (bfm)/ body lean mass (blm) in pcos and their age and body mass index ...

The role and expression of ROCKI and ROCKII in human breast cancer was investigated and the effect on clinical outcome assessed. ROCK knockdown cells (MDA-MB-231DeltaROCKI and MDA-MB-231DeltaROCKII were tested for their in vitro invasiveness, motility and in vivo tumour growth. Samples of fresh frozen breast tumour tissue (n=113) and normal background tissue (n=30) were processed for immunohist...

BACKGROUND To investigate the effects of intraoperative application of dexmedetomidine (Dex) on early gastrointestinal motility after laparoscopic resection of colorectal cancer. METHODS In this prospective, randomized double-blind investigation, 60 patients who underwent laparoscopic resection of colorectal cancer were randomly allocated to receive Dex (DEX group, n = 30) or saline (CON grou...

Background: Ram sperm have a higher polyunsaturated fatty acids and a lower cholesterol/phospholipid ratio than other species which renders the sperm much more vulnerable to oxidative damage caused by reactive oxygen species (ROS). Oxidative stress can affects the integrity of cells at both the structural and sub structural levels. Therefore, a suitable antioxidant may prevent cryo-injuries and...

Antioxidant properties of ghrelin have been demonstrated in recent studies. In the present study, theeffects of chronic administration of ghrelin on the motility and plasma membrane integrity of rat spermatozoa during incubation at 37ºC were investigated. Thirty 45-day-old male Wistar rats were divided into control and treatment groups. Rats in the treatment group were daily injected subcutaneo...
