The effect of post-thaw incubation (0 vs. 5h at 15°C) and straw size (5 vs. 0.5ml) on motility, acrosomal integrity and in vitro fertilizing (IVF) capacity of cryopreserved boar spermatozoa was studied. In samples assessed immediately after thawing, no differences were found between the two straw sizes. After 5h post-thaw incubation, all parameters, except polyspermy, decreased and, spermatozoa...

Background: It is known that vanadyl compounds are capable of alleviating hyperglycemia in streptozotocin induced diabetic rats. Objective: To examine the effect of vanadyl sulphate (VS) on spermatogenesis of male rats. Methods: Male rats (n=10) were administered 32 mg/kg/day of VS orally and 50 mEq/l NaCl (as drinking water) for one month.  Meanwhile, 11 male rats, the control group, received ...

Escherichia coli Hha is an environmental-response regulator of the pathogenic hemolysin operon, and Hha and the contiguous YbaJ are both induced 30-fold in E. coli biofilms (Appl. Microbiol. Biotechnol. 64:515, 2004). Here it is shown that Hha and YbaJ regulate biofilm formation since the hha/ybaJ deletion reduces biofilm mass in microtitre plates (81% in minimal medium, 50% in complex medium) ...

OBJECTIVE To study the contribution of smoking and alcohol consumption to semen quality. DESIGN Retrospective analysis. SETTING University-based fertility clinic. PATIENTS AND METHODS Smoking and alcohol consumption were investigated in a control group (68) and in a group of 47 subjects with defined poor semen quality (PSQ). The control group was composed of subjects whose semen showed a ...

Several studies have been reported on the occurrence of sperm motility inhibiting factors in the male reproductive fluids of different mammalian species, but these proteins have not been adequately purified and characterized. A novel sperm motility inhibiting factor (MIF-II) has been purified from caprine epididymal plasma (EP) by Hydroxylapatite gel adsorption chromatography, DEAE-Cellulose io...

BACKGROUND The objective of the study was to investigate the effects of in vitro zinc sulphate additive to semen extender on sperm parameters (progressive motility, viability, membrane integrity and DNA stability) after cryopreservation. MATERIALS AND METHODS In this Prospective longitudinal laboratory study, semen samples of 5 buffalo bulls of 3-5 years old were collected at 5 different occa...

This study aimed to investigate the effect of supplementing a wheat straw-based diet with Saccharomyces cerevisiae (S.C.) on feed intake, nutrient digestibility, nitrogen balance, body weight and reproduction performance. The experiment was conducted 14 Queue Fine de l’Ouest rams between 3 4 years age (body (B.W.): 54.7 ± 2.03 kg; condition score (B.C.S.): 3.5 0.5), for 80 days during breeding ...

HYPOTHESIS Prosthetic crural closure does not adversely influence esophageal body motility. In most patients, postoperative increased dysphagia resolves spontaneously during the first months after surgery. DESIGN Prospective randomized trial. We compared patients who underwent laparoscopic Nissen fundoplication with simple sutured hiatal closure and those who underwent laparoscopic Nissen fun...

Objectives. SSc is a clinically heterogeneous and generalized disease, characterized by thickness of the connective tissue of the skin and internal organs, such as the digestive tract, impairing gastrointestinal (GI) motility. Our aim is to evaluate retrospectively abnormalities of oesophageal motility, gastric emptying, oro-cecal transit time (OCTT) and small intestine bacterial overgrowth (SI...
