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

Immunoradiometric Assay of Active Renin in Human Plasma: Comparison with Plasma Renin Activity
The direct measurement of active renin with monoclonal antibodies (IRMA) in plasma from hypertensive patients was compared with the traditional PRA method. Two monoclonal antibodies were used: 3E8 and 4G1. The first was coupled to magnetizable beads and was used to trap both active and inactive renin from plasma. The second antibody, 4G1, was iodinated

Secondary Hypertension due to a Renin-secreting Juxtaglomerular Cell Tumor
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.

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

Radioimmunoassay of plasma renin activity.
Abstract We describe a sensitive, simplified radioimmunoassay method for determination of plasma renin activity. Plasma was acidified to the optimal pH (6.0) of angiotensin l generation with the least possible dilution, by using a single addition of hydrochloric acid and the enzyme inhibitor hydroxyquinoline.

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 ...

Collecting Duct Renin Does Not Mediate DOCA-Salt Hypertension or Renal Injury. [PDF]
Collecting duct (CD)-derived renin is involved in the hypertensive response to chronic angiotensin-II (Ang-II) administration. However, whether CD renin is involved in Ang-II independent hypertension is currently unknown.

The internal disruption as hard MHD limit of 1/2 sawtooth like activity in Large Helical Device [PDF]
LHD inward-shifted configurations are unstable to resistive MHD pressure-gradient-driven modes. Sawtooth like activity was observed during LHD operation. The main drivers are the unstable modes $1/2$ and $1/3$ in the middle and inner plasma region which limit the plasma confinement efficiency of LHD advanced operation scenarios.

Internal Structure of the Jets from Young Stars Simulated at Plasma Focus Facilities [PDF]
The laboratory simulations of jets from young stars that have been carried out for many years at plasma focus facilities allow the internal structure of the active regions emerging during the interaction of the jet with the surrounding plasma to be studied in detail.
