to evaluate the acute effect of lovastatin on diabetic endothelial dysfunction, we examined this effect on the aortic rings of streptozotocin-diabetic rats. the endothelial function was assessed in aortic rings isolated from diabetic rats, 12 weeks after treatment with streptozotocin (45 mg/kg, i.p.). the concentration-response curve to acetylcholine (ach) in the aortic rings precontracted with...

conclusions relaxation with guided imagery had a positive effect on mediating anxiety and depression in breast cancer patients. results the experimental group showed significant decreases in insomnia (-0.34 ± 0.83, p < 0.05), pain (-0.28 ± 0.58, p < 0.05), anxiety (-3.56 ± 2.94, p < 0.00), and depression (-2.38 ± 2.70, p < 0.00) between the pretest and the posttest. comparing the two groups, st...

conclusion using standard imaging parameters, each mri sequence reaches its maximum si in a specific contrast concentration, which is highest in se and least in ir in a comparison between se, fse and ir sequences. results this study shows that maximum si will appear at different ranges in different sequences. the maximum si can be seen at concentrations of 5.95, 4.96 and 3.98mmol/l for se, fse ...
