Coupling of respiratory and sympathetic activities in rats submitted to chronic intermittent hypoxia
(Elsevier B.V., 2014-01-01)
The respiratory modulation of sympathetic activity relies on the balance between excitatory and inhibitory inputs from the brainstem respiratory network to presympathetic neurons of the rostral ventrolateral medulla. This ...
Does the median preoptic nucleus contribute to sympathetic hyperactivity in spontaneously hypertensive rats?
(Elsevier B.V., 2016-02-01)
The present study sought to determine the involvement of median preoptic nucleus (MnPO) in the regulation of the cardiovascular function and renal sympathetic activity in normotensive (NT) and spontaneously hypertensive ...
Aerobic exercise training in heart failure: impact on sympathetic hyperactivity and cardiac and skeletal muscle function
(Associação Brasileira de Divulgação Científica, 2011)
Heart failure is a common endpoint for many forms of cardiovascular disease and a significant cause of morbidity and mortality. Chronic neurohumoral excitation (i.e., sympathetic hyperactivity) has been considered to be a ...
Role of the Carotid Body Chemoreflex in the Pathophysiology of Heart Failure: A Perspective from Animal Studies
(Springer New York LLC, 2015)
Neurogenic hypertension and the secrets of respiration
(Amer Physiological Soc, 2017-06-01)
Despite recent advances in the knowledge of the neural control of cardiovascular function, the cause of sympathetic overactivity in neurogenic hypertension remains unknown. Studies from our laboratory point out that rats ...
Guanethidine-mediated destruction of ovarian sympathetic nerves disrupts ovarian development and function in rats
(1990)
Immunosympathectomy produced by treatment of newborn rats with antibodies to nerve growth factor (NGF) delays ovarian development and disrupts estrous cyclicity. While these alterations have been ascribed to loss of ...
Aerobic exercise training in heart failure: impact on sympathetic hyperactivity and cardiac and skeletal muscle function
(Assoc Bras Divulg Cientifica, 2011-09-01)
Heart failure is a common endpoint for many forms of cardiovascular disease and a significant cause of morbidity and mortality. Chronic neurohumoral excitation (i.e., sympathetic hyperactivity) has been considered to be a ...
Global Reach 2018: sympathetic neural and hemodynamic responses to submaximal exercise in Andeans with and without chronic mountain sickness
(American Physiological Society, 2022)
Andeans with chronic mountain sickness (CMS) and polycythemia have similar maximal oxygen uptakes to healthy Andeans. Therefore, this study aimed to explore potential adaptations in convective oxygen transport, with a ...
