The internal disruption as hard MHD limit of 1/2 sawtooth like activity in Large Helical Device [PDF]

Physics of Plasmas 19, 082501 (2012), 2017
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.

Active Janus particles in a complex plasma [PDF]

Phys. Rev. Research 2, 033226 (2020), 2020
Active Janus particles suspended in a plasma were studied experimentally. The Janus particles were micron-size plastic microspheres, one half of which was coated with a thin layer of platinum. They were suspended in the plasma sheath of a radio-frequency discharge in argon at low pressure. The Janus particles moved in characteristic looped trajectories

Severe loss-of-function mutations in the adrenocorticotropin receptor (ACTHR, MC2R) can be found in patients diagnosed with salt-losing adrenal hypoplasia [PDF]

, 2006
Objective: Familial glucocorticoid deficiency type I (FGD1) is a rare form of primary adrenal insufficiency resulting from recessive mutations in the ACTH receptor (MC2R, MC2R).

Cardiac renin and angiotensins: uptake from plasma versus in situ synthesis [PDF]

, 1994
The existence of a cardiac renin-angiotensin system, independent of the circulating renin-angiotensin system, is still controversial. We compared the tissue levels of renin-angiotensin system components in the heart with the levels in blood plasma in ...

Internal Structure of the Jets from Young Stars Simulated at Plasma Focus Facilities [PDF]

Astronomy Letters, 2020, Vol. 46, No. 7, pp. 462-472, 2020
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.

Postural augmentation of plasma renin activity and aldosterone excretion in normal people.

Journal of Clinical Investigation, 1967
Peripheral plasma renin activity and aldosterone excretion rates have been measured in normal people during recumbency, recumbent exercise, tilting, and continuous ambulation. Upright posture induces a prompt elevation in peripheral plasma renin activity

Performance of renin assays in selecting fludrocortisone dose in children with adrenal disorders

Endocrine Connections
Children with salt-wasting adrenal insufficiency are managed with glucocorticoid and mineralocorticoid replacement. Measurement of renin activity or concentration alongside blood electrolyte levels is used to monitor the adequacy of mineralocorticoid ...

Effect of Breed on Plasma Endothelin‐1 Concentration, Plasma Renin Activity, and Serum Cortisol Concentration in Healthy Dogs

Journal of Veterinary Internal Medicine, 2016
Background There are breed differences in several blood variables in healthy dogs. Objective Investigate breed variation in plasma endothelin‐1 (ET‐1) concentration, plasma renin activity, and serum cortisol concentration. Animals Five‐hundred and thirty‐

Modeling the molecular impact of SARS-CoV-2 infection on the renin-angiotensin system [PDF]

arXiv, 2020
SARS-CoV-2 coronavirus infection is mediated by the binding of its spike protein to the angiotensin-converting enzyme 2 (ACE2), which plays a pivotal role in the renin-angiotensin system (RAS). The study of RAS dysregulation due to SARS-CoV-2 infection is fundamentally important for a better understanding of the pathogenic mechanisms and risk factors ...

Active plasma resonance spectroscopy: Eigenfunction solutions in spherical geometry [PDF]

, 2014
The term Active Plasma Resonance Spectroscopy (APRS) denotes a class of related techniques which utilize, for diagnostic purposes, the natural ability of plasmas to resonate on or near the electron plasma frequency: A radio frequent signal (in the GHz range) is coupled into the plasma via an antenna or probe, the spectral response is recorded, and a ...
