Aldosterone-Sensitive Nucleus Tractus Solitarius Neurons Regulate Sensitivity of the Baroreceptor Reflex in High Sodium–Loaded Rats

Journal of Pharmacological Sciences, 2010
We examined the role of aldosterone-sensitive neurons in the nucleus tractus solitarius (NTS) in the arterial baroreceptor reflex (baroreflex) function. Baroreflex sensitivity was induced by phenylephrine in high sodium–loaded rats and was significantly ...

Direct evidences for sympathetic hyperactivity and baroreflex impairment in Tako Tsubo cardiopathy. [PDF]

PLoS ONE, 2014
BackgroundThe exact pathophysiology of Tako-Tsubo cardiomyopathy (TTC) remains unknown but a role for sympathetic hyperactivity has been suggested. Up to now, no direct evidence of sympathetic nerve hyperactivity has been established nor involvement of ...

Arterial baroreflex sensitivity in physiological conditions and cardiovascular diseases

Zdravniški Vestnik, 2005
Background: Arterial baroreceptor reflex is an important mechanism of short-term blood pressure regulation. Arterial baroreceptors are located in the carotid artery and aortic arch walls.

Comparison of Baroreflex Sensitivity and Cardiac Autonomic Function Between Adolescent Athlete and Non-athlete Boys – A Cross-Sectional Study

Frontiers in Physiology, 2019
Introduction: It is well known that regular physical activity improves cardiovascular health, and higher baroreflex sensitivity and heart rate variability are associated with cardiovascular health.

Investigation of the arterial baroreflex mechanism as an automatic regulation system with a double-loop feedback

Известия высших учебных заведений России: Радиоэлектроника, 2015
The arterial baroreflex mechanism as an automatic regulation system with two feedback loops is investigated. The approach for the evaluation of the vascular com.ponent of the baroreflex mechanism has shown.

Potential role of intermittent functioning of baroreflexes in the etiology of hypertension in spontaneously hypertensive rats

JCI Insight, 2020
The spontaneously hypertensive rat (SHR) is a genetic model of primary hypertension with an etiology that includes sympathetic overdrive. To elucidate the neurogenic mechanisms underlying the pathophysiology of this model, we analyzed the dynamic ...

Angiotensin-II-derived reactive oxygen species on baroreflex sensitivity during hypertension: new perspectives

Frontiers in Physiology, 2013
Hypertension is a multifactorial disorder which has been associated with the reduction in baroreflex sensitivity and autonomic dysfunction. Several studies have revealed that increased reactive oxygen species (ROS) generated by nicotinamide adenine ...

Baroreflex gain and time of pressure decay at different body temperatures in the tegu lizard, Salvator merianae.

PLoS ONE, 2020
Ectotherms may experience large body temperature (Tb) variations. Higher Tb have been reported to increase baroreflex sensitivity in ectotherm tetrapods.

Baroreflex Failure

, 2005
The baroreflex receives less attention nowadays because most students of hypertension are convinced that faulty volume regulation by the kidneys is responsible for long-term blood pressure increases.

α-Lipoic Acid Reduces Hypertension and Increases Baroreflex Sensitivity in Renovascular Hypertensive Rats

Molecules, 2012
Renovascular hypertension has robust effects on control of blood pressure, including an impairment in baroreflex mechanisms, which involves oxidative stress.
