Shewanellae are microbial models for environmental stress response; however, the sequential expression of mechanisms in response to stress is poorly understood. Here we experimentally determine the response mechanisms of Shewanella amazonensis SB2B during sodium chloride stress using a novel liquid chromatography and accurate mass-time tag mass spectrometry time-course proteomics approach. The ...

BACKGROUND High level of semen reactive oxygen species is considered as an important factor in male infertility. Sesame has antioxidant properties, which could be effective on improvement of semen parameters. This study was designed to determine the effects of sesame on sperm quality. MATERIALS AND METHODS Twenty-five infertile men entered this clinical trial. They were treated with a 3-month...

The aim of this study was to investigate effects of synchronized intestinal electrical stimulation (SIES) on small intestinal motility in dogs. Seventeen dogs were equipped with a duodenal cannula for the measurement of small bowel motility using manometry; an additional cannula was equipped in six of the dogs with 1.5 m distal to the first one for the measurement of small intestinal transit. T...

Rho GTPases play a pivotal role in tumor progression by regulating tumor cell migration and invasion. However, the role of Rho GTPases in gastric cancer (GC) remains unexplored. This study aimed to investigate the clinical implications of RhoJ, which is an uncharted member of Rho family. RhoJ expression in human GC cell lines and surgical specimens from GC patients were analyzed. Moreover, in v...

this research was carried out to investigate the effects of various levels of dietary organic selenium supplementation (0, 0.1,  0.2 and  0.3 mg/kg) on reproductive traits of rooster. semen was collected using abdominal massage and samples were mixed together. sperm characteristics including percentage of motile, viable and abnormal sperms were assessed. this experiment was carried out based on...

introduction and aims: omeprazole is a gastric parietal cells proton pump inhibitor that is also active against h. pylori in vitro. this study was designed to examine the neutralization of h. pylori cytotoxicity on vero cells by omeprazole micronized in strains isolated from gastritis, ulcer, cancer and barrett's ulcer, to determine whether omeprazole can inhibit vacuolation of the vero cells i...

The objective of this experiment was to test a hypothesis that L-carnitine supplemented diet would improve semen characteristics in 6 adult crossbred AI boars (Hampshire × Pietrain). The control and the tested diet were identical except the tested period (8 weeks) when the diet was supplemented with 2 g of l-carnitine per boar per day. The semen was collected regularly weekly by a gloved-hand t...

background: anti-sperm antibody (asa) can decrease sperm motility and, therefore, it is a cause of male infertility. the aim of this study was to evaluate the effects of varicocelectomy on anti-sperm antibody in patients with varicocele. methods: this observational study was conducted on 90 patients with varicocele at sina and imam khomeini hospitals during 2006 to 2009. all varicocelectomy can...

objective(s) achillea genius is widely used in traditional medicine for gastrointestinal disorders. the aim of this study was to investigate the effects of aqueous-ethanol extract of achillea wilhelmsii on rat’s gastric motility in basal and vagal stimulated conditions. materials and methods twenty four wistar rats were randomly divided into two groups: control and test. the extract was prepare...

background: pentoxifylline (px) prevents camp breakdown by inhibiting the activity of the camp-phosphatase and presumably, stimulates sperm motion. incubation with px causes hyperactivation of sperm, an important step in achieving fertilization, and leads to changes in membranes associated with sperm capacitation. objective: the purpose of this study was to examine the effects of pentoxifylline...
