Coupling between respiratory and sympathetic activities as a novel mechanism underpinning neurogenic hypertension
(2011)
Enhanced sympathetic outflow to the heart and resistance vessels greatly contributes to the onset and maintenance of neurogenic hypertension. There is a consensus that the development of hypertension (clinical and experimental) ...
Long-term facilitation of expiratory and sympathetic activities following acute intermittent hypoxia in rats
(2016-07-01)
Aim: Acute intermittent hypoxia (AIH) promotes persistent increases in ventilation and sympathetic activity, referred as long-term facilitation (LTF). Augmented inspiratory activity is suggested as a major component of ...
Coupling Between Respiratory and Sympathetic Activities as a Novel Mechanism Underpinning Neurogenic Hypertension
(SPRINGER, 2011)
Enhanced sympathetic outflow to the heart and resistance vessels greatly contributes to the onset and maintenance of neurogenic hypertension. There is a consensus that the development of hypertension (clinical and experimental) ...
The nucleus of the solitary tract and the coordination of respiratory and sympathetic activities
(2014)
It is well known that breathing introduces rhythmical oscillations in the heart rate and arterial pressure levels. Sympathetic oscillations coupled to the respiratory activity have been suggested as an important homeostatic ...
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 ...
The carotid body detects circulating tumor necrosis factor-alpha to activate a sympathetic anti-inflammatory reflex
(2022-05-01)
Recent evidence has suggested that the carotid bodies might act as immunological sensors, detecting pro-inflammatory mediators and signalling to the central nervous system, which, in turn, orchestrates autonomic responses. ...
Role of A5 noradrenergic neurons in the chemoreflex control of respiratory and sympathetic activities in unanesthetized conditions
(2017-06-23)
The A5 area at the ventrolateral pons contains noradrenergic neurons connected with other medullary areas involved in the cardiorespiratory control. Its contribution to the cardiorespiratory regulation was previously ...
Short-term sustained hypoxia induces changes in the coupling of sympathetic and respiratory activities in rats
(2014)
Individuals experiencing sustained hypoxia (SH) exhibit adjustments in the respiratory and autonomic functions by neural mechanisms not yet elucidated. In the present study we evaluated the central mechanisms underpinning ...
Tyrosine hydroxylase immunoreactivity as indicator of sympathetic activity: simultaneous evaluation in different tissues of hypertensive rats
(AMER PHYSIOLOGICAL SOC, 2011)
Burgi K, Cavalleri MT, Alves AS, Britto LRG, Antunes VR, Michelini LC. Tyrosine hydroxylase immunoreactivity as indicator of sympathetic activity: simultaneous evaluation in different tissues of hypertensive rats. Am J ...
Sympathetic activity is not increased in L-NAME hypertensive rats
(AMER PHYSIOLOGICAL SOC, 2010)
Santos FM, Dias DPM, Silva CAA, Fazan Jr R, Salgado HC. Sympathetic activity is not increased in L-NAME hypertensive rats. Am J Physiol Regul Integr Comp Physiol 298: R89-R95, 2010. First published November 4, 2009; ...
