The variability of baroreflex sensitivity in juvenile, spontaneously hypertensive rats
(CLINICS CARDIVE PUBL PTY LTD, 2011)
In this study the baroreflex sensitivity of conscious, juvenile, spontaneously hypertensive rats (SHRs) was compared. The study population consisted of 19 eight-week-old male SHRs. The baroreflex sensitivity was quantified ...
High-Pass Filter Characteristics of the Baroreflex - A Comparison of Frequency Domain and Pharmacological Methods
(Public Library Of Science, 2013-11)
Pharmacological methods to assess baroreflex sensitivity evoke supra-physiological blood pressure changes whereas computational methods use spontaneous fluctuations of blood pressure. The relationships among the different ...
Brain nitric oxide production by a proline-rich decapeptide from Bothrops jararaca venom improves baroreflex sensitivity of spontaneously hypertensive rats
(NATURE PUBLISHING GROUP, 2010)
Baroreflex sensitivity is disturbed in many people with cardiovascular diseases such as hypertension. Brain deficiency of nitric oxide (NO), which is synthesized by NO synthase (NOS) in the citrulline-NO cycle (with ...

Day-night pattern of autonomic nervous system modulation in patients with heart failure with and without sleep apnea
(ELSEVIER IRELAND LTD, 2011)
Introduction: Among patients with congestive heart failure (CHF) both obstructive and central sleep apnea (SA) are associated with increased sympathetic activity. However, the day-night pattern of cardiac autonomic nervous ...
Effect of simvastatin in the autonomic system is dependent on the increased gain/sensitivity of the baroreceptors
(Wiley PeriodicalsMalden, 2013-08)
A number of mechanisms have been proposed to explain the pleiotropic effect of statin therapy to reduce sympathetic outflow in cardiovascular disease. We tested the hypothesis that statin treatment could improve baroreflex ...
Baroreflex deficit blunts exercise training-induced cardiovascular and autonomic adaptations in hypertensive rats
(WILEY-BLACKWELL PUBLISHING, INC, 2010)
P>1. Baroreceptors regulate moment-to-moment blood pressure (BP) variations, but their long-term effect on the cardiovascular system remains unclear. Baroreceptor deficit accompanying hypertension contributes to increased ...

Dysautonomias in parkinson's disease: cardiovascular changes and autonomic modulation in conscious rats after infusion of bilateral 6-OHDA in substantia nigra
(2015)
It is important to elucidate the mechanism of dysautonomias in patients with Parkinson's disease; therefore, this study aimed to investigate the cardiovascular and autonomic changes that occur in an animal model of ...
