Neural reflex regulation of arterial pressure in pathophysiological conditions : interplay among the baroreflex, the cardiopulmonary reflexes and the chemoreflex
(1997-04)
The maintenance of arterial pressure at levels adequate to perfuse the tissues is a basic requirement for the constancy of the internal environment and survival. The objective of the present review was to provide information ...
Tonic and reflex cardiovascular autonomic control in trained-female rats
(Associação Brasileira de Divulgação Científica, 2009)
The effects of exercise training on cardiovascular and autonomic functions were investigated in female rats. After an aerobic exercise training period (treadmill: 5 days/week for 8 weeks), conscious female Wistar (2 to 3 ...
Nitric oxide modulation of glutamatergic, baroreflex, and cardiopulmonary transmission in the nucleus of the solitary tract
(Amer Physiological Soc, 2005-01-01)
The neuromodulatory effect of NO on glutamatergic transmission has been studied in several brain areas. Our previous single-cell studies suggested that NO facilitates glutamatergic transmission in the nucleus of the solitary ...
Interação entre o barorreflexo cardiopulmonar e o metaboreflexo muscular no controle cardiorrespiratório em indivíduos jovens saudáveis
(Universidade Federal de São Paulo (UNIFESP), 2021)
The purpose of this study was to investigate if there is an interaction between the muscle metaboreflex and the cardiopulmonary baroreflex for the regulation of ventilation in healthy young subjects. Participants attended ...
Cardiovascular control in experimental diabetes
(Associação Brasileira de Divulgação Científica, 2002-09-01)
Several studies have reported impairment in cardiovascular function and control in diabetes. The studies cited in this review were carried out from a few days up to 3 months after streptozotocin administration and were ...
Avaliação da modulação autonômica cardiovascular de repouso e limitação ventilatória ao exercício físico em indivíduos com diabetes mellitus tipo 2
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Fisioterapia - PPGFtCâmpus São Carlos, 2016-02-29)
This thesis consisted of two studies described below. Study I aimed to evaluate whether
heart period (HP) and systolic arterial pressure (SAP) variability indexes are sensitive
enough to detect the autonomic dysfunction ...
Effects of exercise training on autonomic dysfunction management in an experimental model of menopause and myocardial infarction
(LIPPINCOTT WILLIAMS & WILKINS, 2010)
Objective: The aim of this study was to investigate the effects of exercise training on cardiovascular autonomic dysfunction in ovariectomized rats submitted to myocardial infarction. Methods: Female Wistar rats were divided ...
Estudo da neurotransmissão do quimiorreflexo e do barorreflexo na área A5 de ratos não anestesiados
(Universidade Federal de Minas GeraisUFMG, 2007-09-06)
The circulatory system is essential for the maintenance of body homeostasis. Neural regulation of the cardiovascular system involves the activation of several groups of peripheral sensors that generates the information to ...
Sensibilidade do barorreflexo e respostas cardiorrespiratórias após a ativação e desativação do barorreflexo em ratos depletados de sódio
(Universidade Federal de São CarlosUFSCarPrograma Interinstitucional de Pós-Graduação em Ciências Fisiológicas - PIPGCFCâmpus São Carlos, 2015-10-16)
Cardiorespiratory responses to peripheral baroreceptor activation are affected by sodium balance or anesthesia. In the present study, we investigated the baroreflex sensitivity and cardiorespiratory responses: to baroreceptor ...
Análise das respostas ventilatórias, metabólicas e do controle autonômico cardiovascular durante testes de resistência muscular inspiratória e de determinação da pressão inspiratória crítica
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Fisioterapia - PPGFtCâmpus São Carlos, 2017-02-03)
Respiratory muscle weakness has a strong relationship with autonomic cardiovascular control dysfunction and exercise limitation. For this reason, inspiratory muscle training programs (IMT) have been applied to improve ...
