Sobre os efeitos vasomotôres exercidos pela agua distilada e pelas soluções anisotonicas de clorêto de sodioVaso-motricity induced by distilled water and anisotonic salt solutions
(Fundação Oswaldo Cruz. Instituto Oswaldo Cruz., 2021)
Discharge of RVLM vasomotor neurons is not increased in anesthetized angiotensin II-salt hypertensive rats
(Amer Physiological Soc, 2013-12-01)
Neurons of the rostral ventrolateral medulla (RVLM) are critical for generating and regulating sympathetic nerve activity (SNA). Systemic administration of ANG II combined with a high-salt diet induces hypertension that ...
Role of the caudal pressor area in the regulation of sympathetic vasomotor tone
(Associação Brasileira de Divulgação Científica, 2008-07-01)
It is well known that the ventrolateral medulla contains neurons involved in the tonic and reflex control of the cardiovascular system. Two regions within the ventrolateral medulla were initially identified: the rostral ...
Global REACH 2018: Andean highlanders, chronic mountain sickness and the integrative regulation of resting blood pressure
(Wiley, 2020)
NEW FINDINGS: What is the central question of this study? Does chronic mountain sickness (CMS) alter sympathetic neural control and arterial baroreflex regulation of blood pressure in Andean (Quechua) highlanders? What ...
CARDIOVASCULAR EFFECTS PRODUCED BY MICROINJECTION of ANGIOTENSIN-(1-7) ON VASOPRESSOR and VASODEPRESSOR SITES of the VENTROLATERAL MEDULLA
(Elsevier B.V., 1993-06-11)
In this study, we determined the cardiovascular effects produced by micro-injection of the heptapeptide Angiotensin-(1-7) [Ang-(1-7)] into the rat ventrolateral medulla (VLM). Micro-injection of Ang-(1-7) into the rostral ...
Tibolone in postmenopausal women with systemic lupus erythematosus: A pilot study
(ELSEVIER IRELAND LTD, 2009)
Objective: To determine the influence of the use of tibolone on the frequency of flares of systemic lupus erythematosus (SLE) in postmenopausal patients. Methods: Thirty patients with inactive or controlled SLE were included ...
A FALL in ARTERIAL BLOOD-PRESSURE PRODUCED BY INHIBITION of the CAUDALMOST VENTROLATERAL MEDULLA - the CAUDAL PRESSER AREA
(Elsevier B.V., 1994-11-01)
The caudal edge of the ventrolateral medulla was mapped to localize sites where microinjections of L-glutamate (L-glu) produce presser responses in paralyzed and artificially ventilated urethane-anesthetized rats. Presser ...
Rostral ventrolateral medulla - A source of sympathetic activation in rats subjected to long-term treatment with L-NAME
(Lippincott Williams & Wilkins, 1999-10-01)
The major aim of the present study was to evaluate the role of the rostral ventrolateral medulla (RVLM) in the maintenance of hypertension in rats subjected to long-term treatment with N-G-nitro-L-arginine methyl ester ...
Autonomic control of heart rate during orthostasis and the importance of orthostatic-tachycardia in the snake Python molurus
(Springer, 2014-10-01)
Orthostasis dramatically influences the hemodynamics of terrestrial vertebrates, especially large and elongated animals such as snakes. When these animals assume a vertical orientation, gravity tends to reduce venous return, ...
