Active plasma resonance spectroscopy: A functional analytic description [PDF]

Plasma Sources Sci. Technol. 22 (2013) 025005, 2012
The term "Active Plasma Resonance Spectroscopy" refers to a class of diagnostic methods which employ the ability of plasmas to resonate on or near the plasma frequency. The basic idea dates back to the early days of discharge physics: An signal in the GHz range is coupled to the plasma via an electrical probe; the spectral response is recorded, and ...

Treatment with patiromer decreases aldosterone in patients with chronic kidney disease and hyperkalemia on renin-angiotensin system inhibitors [PDF]

, 2016
Elevated serum aldosterone can be vasculotoxic and facilitate cardiorenal damage. Renin-angiotensin system inhibitors reduce serum aldosterone levels and/or block its effects but can cause hyperkalemia.

Plasma renin activity by LC-MS/MS: development of a prototypical clinical assay reveals a subpopulation of human plasma samples with substantial peptidase activity.

Clinical Chemistry, 2010
BACKGROUND For management and treatment of secondary hypertension, plasma renin activity (PRA) assay is considered an essential diagnostic tool. We developed a liquid chromatography-tandem mass spectrometry (LC-MS/MS)-based approach to PRA offering ...

Axion production in unstable magnetized plasmas: an active source of dark-matter [PDF]

Phys. Rev. D 101, 051701 (2020), 2019
Axions, the hypothetical particles restoring the charge-parity symmetry in the strong sector of the Standard Model, and one of the most prone candidates for dark matter, are well-known to interact with plasmas. In a recent publication [Phys. Rev. Lett.

Secondary Hypertension due to a Renin-secreting Juxtaglomerular Cell Tumor

Journal of the Formosan Medical Association, 2010
A juxtaglomerular cell tumor (JCT) is a rare, renin-secreting tumor of the kidney and can cause hypertension. JCT is pathologically benign, and resection of the tumor is curative for hypertension.

Reduced blood pressure in sickle cell disease is associated with decreased angiotensin converting enzyme (ACE) activity and is not modulated by ACE inhibition.

PLoS ONE, 2022
BackgroundSickle cell disease (SCD) incurs vaso-occlusive episodes and organ damage, including nephropathy. Despite displaying characteristics of vascular dysfunction, SCD patients tend to present relatively lower systemic blood pressure (BP), via an ...

How to Patch Active Plasma and Collisionless Sheath: Practical Guide [PDF]

, 2002
Most plasmas have a very thin sheath compared with the plasma dimension. This necessitates separate calculations of the plasma and sheath. The Bohm criterion provides the boundary condition for calculation of plasma profiles. To calculate sheath properties a value of electric field at the plasma-sheath interface has to be specified in addition to the ...

Simulation of plasma water interaction with discharge in the existing bubble in water [PDF]

arXiv, 2022
The plasma-liquid interaction is an important issue in plasma technology. The simulation of discharge in spherical bubbles in the water that produced plasma-activated water (PAW) is investigated using finite element methods (FEM) for a simulated 2D dielectric barrier discharge in three different geometries.

The associations of adipokines with selected markers of the renin-angiotensinogen-aldosterone system: the multi-ethnic study of atherosclerosis. [PDF]

, 2015
Among obese individuals, increased sympathetic nervous system (SNS) activity results in increased renin and aldosterone production, as well as renal tubular sodium reabsorption.

Regulation of Renin Release via Cyclic ADP-Ribose-Mediated Signaling: Evidence from Mice Lacking CD38 Gene

Cellular Physiology and Biochemistry, 2013
Background/Aims: Despite extensive studies, the intracellular regulatory mechanism of renin production and release is still poorly understood. The present study was designed to test whether CD38-ADP-ribosylcyclase signaling pathway contributes to the ...
