To investigate the channels and neurotransmitters in the ventrolateral medulla (VLM) oblongata that are responsible for the maintenance of sympathetic tone and cardio-respiratory reflex regulation. Microinjections of excitant amino acid (glutamate, 100 nl, 100 mM), calcium channel blockers, agonists and antagonists were made throughout the VLM in anaesthetized rats. Arterial blood pressure, sym...

The objective of this study was to determine the chronology of changes in blood pressure in renalhypertension induced by solid plexiglass clips in rats. Saw blades with the thickness of 0.21-0.22 mm wereused to make clips sized 4 × 2 × 2 mm from a piece of 2-mm thick plexiglass. Rats were subjected to shamoperation or left renal arterial clipping, and 1, 2, 3 and 4 weeks later blood pressure, a...

fuzzy controllers are being used in various control schemes. the aim of this work was adjusting hemodialysis machine parameters utilizing a fuzzy logic controller (flc) so that patient’s hemodynamic condition remains stable during hemodialysis treatment. for this purpose a comprehensive mathematical model of the arterial pressure response during hemodialysis, including hemodynamic, osmotic, and...

background:  patients undergoing cemented hip hemiarthroplasty may develop bone cement implantation syndrome (bcis) which is a leading cause of intraoperative complications. the purpose of this study was to evaluate cardiovascular changes during cemented hip hemiarthroplasty in elderly patients.   methods:  cemented hip hemiarthroplasty was performed on 72 patients with femoral neck fracture. a...

Objectives Our study aims to provide basic scientific data on the importance of obesity management in middle-aged Korean women by analyzing its effects on blood pressure and arterial stiffness. In addition, we examined the correlations of these two parameters. Methods The study participants were 40 middle-aged female volunteers, who were classified into obesity group (n = 20) and normal weigh...

BACKGROUND Diet has been reported to influence arterial blood pressure, and evidence indicates that the Mediterranean diet reduces cardiovascular mortality. OBJECTIVE The objective was to examine whether the Mediterranean diet, as an entity, and olive oil, in particular, reduce arterial blood pressure. DESIGN Arterial blood pressure and several sociodemographic, anthropometric, dietary, phy...
