the constitutive relationships of the rubber materials that act as the main spring of a hydraulic engine mount are nonlinear. in addition to material induced nonlinearity, further nonlinearities may be introduced by mount geometry, turbulent fluid behavior, temperature, boundary conditions, decoupler action, and hysteretic behavior. in this research all influence the behavior of the system only...

background: the present study aimed to determine the prevalence and associated risk factors of vaginal trichomoniasis in women referred to gynecologic clinic in benha university hospital, egypt. methods: two hundred female patients enrolled in the study. vaginal samples were obtained from them and examined for t. vaginalis by wet mount, giemsa stain, acridine orange (ao) stain and culture on mo...

Kaempferia parviflora Wall. Ex. Baker (Krachaidum) has long been used among Thai men for sexual enhancement. The aim of this study was to determine the effect of K. parviflora ethanolic extract on the sexual behavior of male rats and its toxicity. The experiment was divided into three groups of rats given K. parviflora extract at doses of 60, 120, and 240 mg/kg BW for 60 days, whilst a control ...

The present report focuses on novel animal models of male infertility: genetically defined mice bearing single-gene mutations that induce infertility. The primary goal of our investigations was to identify the reproductive defects in these mutant mice. The phenotypic effects of the gene mutations were deciphered by comparing the mutant mice to their normal siblings. Initially testicular steroid...

In addition to food intake and energy balance regulation, ghrelin mediate the rewarding and motivational properties of palatable food as well as addictive drugs. The ability of ghrelin to regulate reinforcement involves the cholinergic-dopaminergic reward link, which encompasses a cholinergic projection from the laterodorsal tegmental area (LDTg) to the ventral tegmental area (VTA) together wit...

We investigated the effects of continuous intracerebroventricular infusion of a melanocortin 4 receptor antagonist HS014 (cyclic [AcCys11, D-Nal14, Cys18, Asp-NH2(22)]beta-MSH-(11-22)) over 12 days and a subsequent 12-day recovery period on food intake, body weight and copulatory behavior in male rats. The results show that the food intake increased immediately after the start of the infusion o...
