Sympathetic nerve-derived ATP regulates renal medullary blood flow via vasa recta pericytes [PDF]

, 2013
Pericyte cells are now known to be a novel locus of blood flow control, being able to regulate capillary diameter via their unique morphology and expression of contractile proteins. We have previously shown that exogenous ATP causes constriction of vasa

Transcutaneous vagus nerve stimulation: retrospective assessment of cardiac safety in a pilot study. [PDF]

, 2012
Background: Vagus nerve stimulation has been successfully used as a treatment strategy for epilepsy and affective disorders for years. Transcutaneous vagus nerve stimulation (tVNS) is a new non-invasive method to stimulate the vagus nerve, which has been

Electric Nerve Stimulation to Monitor the Efficacy of Renal Denervation [PDF]

Hypertension, 2013
See related article, pp 450–456 In 2009, Krum et al1 reported a substantial blood pressure decrease (−27/17 mm Hg at 12 months) after percutaneous radiofrequency catheter-based renal sympathetic denervation in a cohort of 45 patients with resistant hypertension.

Transcutaneous Electrical Nerve Stimulation (TENS) A Possible Aid for Pain Relief in Developing Countries? [PDF]

, 2009
Transcutaneous electrical nerve stimulation (TENS) refers to the delivery of electrical currents through the skin to activate peripheral nerves. The technique is widely used in developed countries to relieve a wide range of acute and chronic pain ...

Impacts of Renal Sympathetic Activation on Atrial Fibrillation: The Potential Role of the Autonomic Cross Talk Between Kidney and Heart

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017
Background Recent studies have demonstrated that there is a high variability of renal sympathetic nerve density distribution from proximal to distal renal artery segments.

Case report: SGLT2i, transcutaneous vagus nerve stimulation, and their effects on intrarenal venous flow pattern in HFpEF

Frontiers in Neuroscience, 2022
Renal congestion in heart failure (HF) is a predictor of the prognosis of cardiovascular disease. The effect of sodium-glucose cotransporter 2 inhibitors (SGLT2i) and vagus nerve stimulation (VNS) on renal congestion has not been reported in HF.

Evidence that blood pressure remains under the control of arterial baroreceptors in renal hypertensive rats

Brazilian Journal of Medical and Biological Research, 2009
The purpose of the present study was to determine the range of the influence of the baroreflex on blood pressure in chronic renal hypertensive rats. Supramaximal electrical stimulation of the aortic depressor nerve and section of the baroreceptor nerves (

GABA in Paraventricular Nucleus Regulates Adipose Afferent Reflex in Rats. [PDF]

PLoS ONE, 2015
Chemical stimulation of white adipose tissue (WAT) induces adipose afferent reflex (AAR), and thereby causes a general sympathetic activation. Paraventricular nucleus (PVN) is important in control of sympathetic outflow.

Changes in Renal Blood Flow During Renal Nerve Stimulation

Experimental Biology and Medicine, 1971
SummaryChanges in canine renal blood flow (RBF) during direct renal nerve stimulation (RNS) were measured with an electromagnetic flowmeter in the presence and absence of autonomic blocking drugs. The degree of renal vasoconstriction increases as frequency of RNS is increased from 2 to 10 cps.
