The effects of the muscle mechanoreflex on the arterial baroreflex neural control have not previously been analyzed over the entire operating range of the arterial baroreflex. In anesthetized, vagotomized, and aortic-denervated rabbits (n = 8), we isolated carotid sinuses and changed intracarotid sinus pressure (CSP) from 40 to 160 mmHg in increments of 20 mmHg every minute while recording rena...

BACKGROUND Social network analysis (SNA) has been widely used across a range of disciplines but is most commonly applied to help improve the effectiveness and efficiency of decision making processes in commercial organisations. We are utilising SNA to inform the development and implementation of tailored behaviour-change interventions to improve the uptake of evidence into practice in the Engli...

NINOMIYA, ISHIO, NAOKO NISIMARU, AND HIROSHI IRISAWA. Sympathetic nerve activity to the spleen, kidney, and heart in response to baroceptor input. Am. J. Physiol. 221(5): 1346-1351. 1971.-The effects of the baroceptor reflex on sympathetic nerve activity (SNA) to spleen, kidney, and heart were analyzed in anesthetized cats. The baroceptor reflex times of SNA to the spleen, kidney, and heart wer...

A baroreflex equilibrium diagram describes the relation between input pressure and sympathetic nerve activity (SNA) and that between SNA and arterial pressure (AP). To calibrate the SNA axis (abscissa) of the baroreflex equilibrium diagram, the AP response to intravenous bolus injections of phenylephrine (0.2-50 μg/kg) or norepinephrine (NE, 0.02-5 μg/kg) was examined in normal control rats (NC...

22 The sympathoexcitatory response to insulin is mediated by neurons in the arcuate 23 nucleus (ARC) and hypothalamic paraventricular nucleus (PVH). Previous studies have 24 reported that stimulation of ARC neurons increases sympathetic nerve activity (SNA) 25 and arterial blood pressure (ABP) through glutamate receptor activation in the PVH. 26 Therefore, the purpose of the present study was t...

PURPOSE Thiazides are suggested as a treatment for intensive care unit (ICU)-acquired hypernatremia (IAH). The primary aim of the study was reducing serum sodium concentration (sNa) in patients with IAH with hydrochlorothiazide (HCT) in comparison to placebo. Secondary end points were a difference in urine sodium concentration (uNa) and duration of severe IAH. MATERIALS A monocentric, double-...

Social network analysis (SNA) is not a formal theory in sociology but rather a strategy for investigating social structures. As it is an idea that can be applied in many fields, we study, in particular, its influence in the information sciences. Information scientists study publication, citation and cocitation networks, collaboration structures and other forms of social interaction networks. Mo...

The arterial baroreflex system can be divided into the neural arc, from pressure input to efferent sympathetic nerve activity (SNA), and the peripheral arc, from SNA to arterial pressure (AP). Plotting the neural and peripheral arcs on a pressure-SNA plane yields a baroreflex equilibrium diagram. We examined the effects of vagotomy on the open-loop static characteristics of the carotid sinus ba...
