Centrally acting antihypertensives change the psychogenic cardiovascular reacti...
Mendonça, Michelle M.; Costa, Amanda N.; Moraes, Gean C.A.; Martins, Gustavo M.; Almeida, Aline F.; Rincon, Gabriel C.N.; Siqueira, João P.R.Made available in DSpace on 2021-06-25T11:12:32Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-01; Clonidine (CL) and Rilmenidine (RI) are among the most frequently prescribed centrally acting antihypertensives. Here, we compared CL and RI effects on psychogenic cardiovascular reactivity to sonant, luminous, motosensory, and vibrotactile stimuli during neurogenic hypertension. The femoral artery and ...
Chronic treatment with ivabradine does not affect cardiovascular autonomic cont...
Silva, Fernanda Cacilda dos Santos; Paiva, Franciny Aparecida; Ribeiro, Flavia Camargos de Figueiredo Müller; Caldeira, Henrique Martins ArantesA low resting heart rate (HR) would be of great benefit in cardiovascular diseases. Ivabradine-a novel selective inhibitor of hyperpolarization-activated cyclic nucleotide gated (HCN) channels- has emerged as a promising HR lowering drug. Its effects on the autonomic HR control are little known. This study assessed the effects of chronic treatment with ivabradine on the modulatory, reflex and tonic cardiovascul...
The dorsomedial hypothalamus and the central pathways involved in the cardiovas...
Fontes, Marco Antônio Peliky; Custódio, Carlos Henrique Xavier; Menezes, Rodrigo Cunha Alvim de; DiMicco, Joseph A.Psychological stress elicits increases in sympathetic activity accompanied by a marked cardiovascular response. Revealing the relevant central mechanisms involved in this phenomenon could contribute significantly to our understanding of the pathogenesis of stress-related cardiovascular diseases, and the key to this understanding is the identification of the nuclei, pathways and neurotransmitters involved in the...

Bezold-Jarisch reflex in sino-aortic denervated malnourished rats.
Bezerra, Vanessa Moraes; Xavier, Carlos Henrique; Menezes, Rodrigo Cunha Alvim de; Fontes, Marco Antônio Peliky; Cardoso, Leonardo MáximoIn this study we assessed the role of Bezold–Jarisch reflex (BJR) in the regulation of blood pressure (BP) of malnourished (MN) and control rats (CN) with sino-aortic denervation (SAD). Fischer rats were fed diets containing either 6% (MN) or 15% (CN) protein for 35 days after weaning. These rats underwent sham or SAD and catheterization of femoral artery and vein for BP measurements and drug injection. Phenylb...

Bezerra, Vanessa Moraes; Xavier, Carlos Henrique; Fernandes, Luciano Gonçalves; Cardoso, Leonardo Máximo; Fontes, Marco Antônio PelikyMalnutrition 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 renal sympathetic nerve activity (RSNA) evoked from Bezold–Jarischreflex (BJR). Fischer rats were fed diets containing either (6% malnourished or 14% control) protein for 35 days after weaning. ...
