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 ...

Baroreflex Dysfunction in Prader Willi Syndrome [PDF]

Journal of Clinical and Diagnostic Research, 2016
Prader-Willi syndrome is a classical hypothalamic insufficiency disorder. This syndrome is often associated with cardiovascular morbidity and mortality - which could probably be attributed to autonomic dysfunction.

Baroreflex sensitivity in frailty syndrome

Brazilian Journal of Medical and Biological Research, 2019
Frailty is related to a decrease in the physiological reserves, which causes difficulties in maintaining homeostasis. An example of physiological mechanisms for cardiovascular homeostasis is the baroreflex. The aim of this study was to compare baroreflex

High-pass filter characteristics of the baroreflex--a comparison of frequency domain and pharmacological methods. [PDF]

PLoS ONE, 2013
Pharmacological methods to assess baroreflex sensitivity evoke supra-physiological blood pressure changes whereas computational methods use spontaneous fluctuations of blood pressure.

Angiotensin II-superoxide-NFκB Signaling and Aortic Baroreceptor Dysfunction in Chronic Heart Failure

Frontiers in Neuroscience, 2015
Chronic heart failure (CHF) affects approximately 5.7 million people in the United States. Increasing evidence from both clinical and experimental studies indicates that the sensitivity of arterial baroreflex is blunted in the CHF state, which is a ...

Effects of transient change in carotid arterial stiffness on arterial baroreflex during mild orthostatic stimulation

Artery Research, 2012
Stiffening of central conduit arteries –areas where the mechanoreceptors are embedded (e.g., ascending aorta and carotid artery) – is considered to be associated with the impaired baroreflex control in response to hypotensive stress.

Hypertension in obesity: A focus on individualized pharmacotherapy and the role of body composition, on behalf of the European Society of Hypertension Working Group on Diabetes and Metabolic Risk Factors and Working Group on Lifestyle, Cardiovascular Pharmacotherapy and Adherence

British Journal of Clinical Pharmacology, EarlyView.
Hypertension in obesity represents a major global health challenge, closely linked to the global epidemics of obesity, type 2 diabetes and metabolic dysfunction. Excess adiposity contributes to elevated blood pressure through multiple, interrelated mechanisms, including activation of the renin–angiotensin–aldosterone system, sympathetic nervous system ...

Hydrogen Sulfide Facilitates the Impaired Sensitivity of Carotid Sinus Baroreflex in Rats with Vascular Calcification

Frontiers in Pharmacology, 2017
Arterial baroreflex is a general mechanism maintaining cardiovascular homeostasis; its sensitivity is reduced in vascular calcification (VC). Hydrogen sulfide (H2S) treatment facilitates baroreflexive sensitivity in normal and hypertensive rats. Here, we

The carotid body as a putative therapeutic target for the treatment of neurogenic hypertension [PDF]

, 2013
In the spontaneously hypertensive (SH) rat, hyperoxic inactivation of the carotid body (CB) produces a rapid and pronounced fall in both arterial pressure and renal sympathetic nerve activity (RSA).
