objective(s): nucleus raphe magnus (nrm) that is involved in the regulation of body temperature contains nitric oxide (no) synthase. considering the effect of no on skin blood flow control, in this study, we assessed its thermoregulatory role within the raphe magnus. materials and methods: to this end, tail blood flow of male wistar rats was measured by laser doppler following the induction of ...

abstract introduction: there are many studies about the inhibitory effect of the esophageal distention (ed) on gastric motility. recently, it has been shown that ed decreases the gastric secretions. it is well established that the inhibitory effect of ed is mediated by activation of vago-vagal inhibitory reflex. however, there is not any investigation about the effect of the reflex on the gastr...

In the present study, the nonlinear model of non-Newtonian blood flow in cosine-shape stenosed elastic artery is numerically examined. The model is carried out for axisymmetric, two-dimensional and fully developed blood flow. The vessel wall is assumed to be have time-dependent radius that is important factor for study of blood flow. The cosine-shape stenosis convert to rigid artery by using a ...

vertebrobasilar insufficiency is the cause of cerebrovascular accidents in 20% of cases. there are few reports regarding spectral doppler indices (sdis) of vertebral arteries (vas) normal blood flow. the objective of this study was to provide basic reference data about sdis of vas normal blood flow separately and in comparison with internal carotid arteries (icas) and common carotid arteries (c...

Abstract Introduction: There are many studies about the inhibitory effect of the esophageal distention (ED) on gastric motility. Recently, it has been shown that ED decreases the gastric secretions. It is well established that the inhibitory effect of ED is mediated by activation of vago-vagal inhibitory reflex. However, there is not any investigation about the effect of the reflex on the gast...

Arterial drug concentration distribution determines local toxicity. The safety issues dealt with Drug-Eluting Stents (DESs) reveal the needs for investigation about the effective factors contributing to fluctuations in arterial drug uptake. The current study focused on the importance of hypertension as an important and controversial risk factor among researchers on the efficacy of Heparin-Eluti...
