Cardiovascular and postural control systems have been studied independently despite the increasing evidence showing the importance of cardiopostural interaction in blood pressure regulation. In this study, we aimed to assess the role of the cardiopostural interaction in relation to cardiac baroreflex in blood pressure regulation under orthostatic stress before and after mild exercise. Physiolog...

Introduction: The bed nucleus of the stria terminalis (BST) is a limbic structure which is involved in cardiovascular regulation and baroreflex modulation. The presence of cholinergic synaptic terminalis with high level of muscarinic receptors in the BST has been demonstrated. This study was performed to find the role of the cholinergic muscarinic receptor in cardiovascular response and baro...

One of the key factors affecting leakage in water distribution systems is network pressure management by putting Pressure Reduce Valves (PRV) in the flow path and optimal regulation of these vales in water networks. This study aimed at investigating optimal pressure management problems so as to minimize leakage in water distribution networks. To do so, an approach was proposed for both optimal ...

The study of the performance dynamic hydraulic throttling under condition stable fluid is great significance. effect a step change in pressure differences on valve studied. This paper studies and static hydraulic-valve-outlet throttling-speed regulation system, builds more accurate mathematical model, considers linear factors flow hydraulic-valve throttling, analyzes influence step-load differe...

Introduction: It has been approved that in most tissues NO production increases during acute inflammation and Angiotensin II has a role in production of reactive oxygen species (ROS). As regulation of joint blood flow (JBF) is important in this situation, this study was performed to investigate the interaction of local Ang II and ROS production and the modulatory role of NO on regulation of JBF...
