BACKGROUND AND AIMS The mechanisms underlying intestinal secretion in rotavirus diarrhoea remain to be established. We previously reported that rotavirus evokes intestinal fluid and electrolyte secretion by activation of the enteric nervous system. We now report that antagonists for the 5-hydroxytryptamine 3 receptor (5-HT(3)) and vasoactive intestinal peptide (VIP) receptor, but not antagonist...

We investigated the laxative and anti-diarrheal activity of polycarbophil, an insoluble hydrophilic polymer, in comparison with other agents used for treating functional bowel disorder (FBD). In naive rats, polycarbophil (500 mg/kg) increased fecal weight and water contents without producing diarrhea. Carboxymethylcellulose (CMC) did not produce evident changes in bowel movement. Picosulfate ma...

PURPOSE To evaluate the effects of sunitinib, a multitargeted tyrosine kinase inhibitor, on the QT interval in patients with cancer. EXPERIMENTAL DESIGN Patients received sunitinib loading doses (150-200 mg) on days 3 and 9 and maintenance doses (50 mg/d) on days 4 to 8. Moxifloxacin (day 1), placebo (day 2), and granisetron [with placebo (day 2) or sunitinib (days 3 and 9)] were also adminis...

objectives: the aim of this randomized clinical trial was to assess the efficacy of stimdate compared to ritalin in the treatment of children with attention deficit hyperactivity disorder (adhd). method: sixty four subjects (45 boys and 15 girls) aged 5-13 who were diagnosed with adhd based on (dsm-iv-tr) criteria were selected for this study. the subjects were randomly assigned to two groups: ...

this contrastive study, in the first place, examined the generic structure and, in the second place, explored the face theory proposed by arundale (2006) in 140 doctoral dissertation acknowledgments written by native speakers of persian (nsp) and native speakers of english (nse) in 7 disciplines representing soft sciences to find out what discourse genre components writers employ to articulate ...

Hybrids as various resources have valuable importance in tree breeding. Today, improvement programs by using poplar and willows and their hybrids play basic role in supplying wood and decreasing pressure on natural forests. This research was carried out in order to study inter-generic hybridization possibility between Salix aegyptica and Populus caspica species from Salicaceae to achieve new hy...

Notice of formal retraction of article by Dr Y. Fujii. This article is being retracted as a result of: (1) Overwhelming evidence of fabrication, related to the fact that the distributions of many variables reported by Dr Fujii in these studies could not have occurred by chance; 2 and (2) The inability of Dr Fujii’s institutions to attest to the integrity of the study and/or its data conducted u...

Scopolamine is a high affinity muscarinic antagonist that is used for the prevention of post-operative nausea and vomiting. 5-HT3 receptor antagonists are used for the same purpose and are structurally related to scopolamine. To examine whether 5-HT3 receptors are affected by scopolamine we examined the effects of this drug on the electrophysiological and ligand binding properties of 5-HT3A rec...
