Sympathoinhibition to Bezold–Jarisch reflex is attenuated in protein malnourished rats
(2011-01)
Malnutrition affects cardiovascular reflexes, including chemoreflex and baroreflex. In this study we assessed the hypothesis that malnourishment changes the responses in mean arterial pressure (MAP), heart rate (HR) and ...
Papel Dos Nervos Renais, Corpúsculos Carotídeos E Aldosterona Na Hipertensão Arterial Renovascular De Goldblatt
(Universidade Federal de São Paulo (UNIFESP), 2017-08-31)
Introduction: It is already known that sympathetic nervous system (SNS), carotid body (CB) hypertonicity and renin-angiotensin-aldosterone system (RAAS) have an important role in the generation and maintenance of renovascular ...
Endogenous hydrogen peroxide in the hypothalamic paraventricular nucleus regulates sympathetic nerve activity responses to L-glutamate
(Amer Physiological Soc, 2012-11-01)
Cardoso LM, Colombari E, Toney GM. Endogenous hydrogen peroxide in the hypothalamic paraventricular nucleus regulates sympathetic nerve activity responses to L-glutamate. J Appl Physiol 113: 1423-1431, 2012. First published ...

Efeitos cardiovasculares ao tratamento crônico com vitamina C na hipertensão renovascular em ratos Wistar
(Universidade Federal de São Paulo (UNIFESP), 2010-01-27)
Sympathetic vasomotor hyperactivity and baroreflex dysfunction are involved in the development and maintenance of Goldblatt 2 kidney, 1 clip (2K-1C) model of renovascular arterial hypertension (AH). This experimental model ...
Effect of inhibition of nitric oxide synthase on blood pressure and renal sodium handling in renal denervated rats
(Associação Brasileira de Divulgação Científica, 2000)
Sympathetic overactivity occurs before hypertension in the two-kidney, one-clip model
(2016-01-01)
New Findings: What is the central question of this study? The aim was to evaluate whether elevated sympathetic nerve activity (SNA) occurs before the onset of arterial hypertension in a rat renovascular model of hypertension, ...
Oxidative Stress in the Sympathetic Premotor Neurons Contributes to Sympathetic Activation in Renovascular Hypertension
(Nature Publishing Group, 2009-05-01)
BACKGROUNDBased on previous data, we hypothesized that an increase of angiotensin II (Ang II)-via the Ang II type 1 (AT-1) receptor-in the rostral ventrolateral medulla (RVLM) and the paraventricular nucleus (PVN) of the ...
Efeitos cardiovasculares e renais da denervação seletiva das fibras sensoriais renais na Hipertensão Renovascular Experimental
(Universidade Federal de São Paulo (UNIFESP), 2019-07-25)
It is known that oxidative stress and increased renal sympathetic nervous activity (rSNA) play an important role in arterial hypertension (AH). Under physiological conditions, renal sympathetic fibers control renin release, ...
