Involvement of the median preoptic nucleus in blood pressure control
(Neuroscience Letters, 2014-01-13) [Artigo]
Studies have demonstrated that median preoptic nucleus (MnPO) neurons play a role in organizing the cardiovascular responses induced by changes in the circulating blood volume. The present study examined whether the MnPO ...
Recovery of high blood pressure after chronic lesions of the commissural NTS in SHR
(Hypertension, 2003-10-01) [Artigo]
Acute electrolytic lesions of the commissural nucleus of the solitary tract (commNTS) reduce blood pressure (BP) in SHR but not in normotensive Wistar-Kyoto and Wistar rats and abolish the pressor response to intravenous ...
Inhibition of central angiotensin II-induced pressor responses by hydrogen peroxide
(Neuroscience, 2010-12-01) [Artigo]
Hydrogen peroxide (H(2)O(2)) important reactive oxygen species produced endogenously, may have different physiological actions The superoxide anion (O(2)(-)) is suggested to be part of the signaling mechanisms activated ...
ROLE OF CAROTID BODY TO HYPERTENSION AND PULMONAR VENTILATION IN RENOVASCULAR HYPERTENSIVE RATS
(Faseb Journal, 2017-04-01) [Resumo]
Effects of acetylcholine and cholinergic antagonists on the activity of nucleus of the solitary tract neurons
(Brain Research, 2017-03-15) [Artigo]
Previously we have demonstrated that microinjection of acetylcholine (ACh) into the intermediate nucleus of the solitary tract (iNTS) induced sympatho-inhibition combined with a decrease in the phrenic nerve activity (PNA), ...
Cardiovascular effects of chronically increasing angiotensin II type 2 receptor expression in the nucleus of the solitary tract
(Faseb Journal, 2014-04-01) [Resumo]
Cardiovascular responses to injections of angiotensin II or carbachol into the rostral ventrolateral medulla in rats with AV3V lesions
(Neuroscience Letters, 2013-11-27) [Artigo]
Injection of L-glutamate (GLU) into the rostral ventrolateral medulla (RVLM) produces sympathetically-mediated pressor responses that depend on the integrity of the tissue surrounding the anteroventral third ventricle (AV3V ...
Leptin into the ventrolateral medulla facilitates chemorespiratory response in leptin-deficient (ob/ob) mice
(Acta Physiologica, 2014-05-01) [Artigo]
AimLeptin, an adipocyte-derived hormone, is suggested to participate in the central control of breathing. We hypothesized that leptin may facilitate ventilatory responses to chemoreflex activation by acting on respiratory ...
Importance of angiotensinergic mechanisms for the pressor response to L-glutamate into the rostral ventrolateral medulla
(Brain Research, 2010-03-31) [Artigo]
Pressor responses to L-glutamate into the rostroventrolateral medulla (RVLM) are reduced by lesions of the anteroventral third ventricle (AV3V) region, a main site related to central angiotensinergic pressor mechanisms. ...
Central mechanisms involved in pilocarpine-induced pressor response
(Autonomic Neuroscience-basic & Clinical, 2011-10-28) [Artigo]
Pilocarpine (cholinergic muscarinic agonist) injected peripherally may act centrally to produce pressor responses; in the present study, using c-fos immunoreactive expression, we investigated the forebrain and brainstem ...
