Commissural NTS lesions and cardiovascular responses in aortic baroreceptor-denervated rats
Both acute (1 day) lesions of the commissural nucleus of the solitary tract (commNTS) and aortic baroreceptor denervation increase pressor responses to bilateral common carotid occlusion (BCO) during a 60-second period in ...
Role of brain nitric oxide in the cardiovascular control of bullfrogs
The goal of the present study was to determine if nitric oxide (NO) acting on the brain of bullfrog (Lithobates catesbeianus) is involved in arterial pressure and heart rate (HR) control by influencing sympathetic activity. ...
Echocardiographic Doppler estimation of pulmonary artery pressure in critically ill patients with severe hypoxemia
BACKGROUND: In spontaneously breathing cardiac patients, pulmonary artery pressure (PAP) can be accurately estimated from the transthoracic Doppler study of pulmonary artery and tricuspid regurgitation blood flows. In ...
Estudo comparativo dos efeitos hemodinâmicos e ventilatórios da ventilação controlada a volume ou a pressão, em cães submetidos ao pneumoperitônio
BACKGROUND AND OBJECTIVES: Pressure controlled ventilation (PCV) is available in anesthesia machines, but there are no studies on its use during CO 2 pneumoperitoneum (CPP). This study aimed at evaluating pressure-controlled ...
GENOME-WIDE ASSOCIATION STUDY IDENTIFIES SIX NEW LOCI INFLUENCING PULSE PRESSURE AND MEAN ARTERIAL PRESSURE

Effects of mercury on the arterial blood pressure of anesthetized rats
The available data suggests that hypotension caused by Hg2+ administration may be produced by a reduction of cardiac contractility or by cholinergic mechanisms. The hemodynamic effects of an intravenous injection of HgCl2 ...
