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 ...

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

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 ...

Adverse Cardiovascular Risk Profile and Increased Diurnal Salivary Cortisol in Girls With Turner Syndrome: An Exploratory Study

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Patients with Turner Syndrome (TS) and those exposed to high concentrations of glucocorticoids have a number of characteristics in common, including an increased risk of cardiovascular disease. Pediatric TS patients underwent studies of salivary cortisol (SC) and cortisone (SCn), body composition, continuous glucose monitoring, vascular ...

Measurement of Renin Activity in Human Plasma [PDF]

Circulation Research, 1965
A method is described for estimating plasma renin activity by using renin substrate present in plasma. This method differs from other indirect renin assay methods by (1) incubation in the absence of ions thus establishing conditions for zero order kinetics for the reaction between endogeneous renin and substrate and (2) the use of ...

Sex differences in soluble prorenin receptor in patients with type 2 diabetes

Biology of Sex Differences, 2021
Background The soluble prorenin receptor (sPRR), a member of the renin-angiotensin system (RAS), is elevated in plasma of patients with preeclampsia, hypertension, chronic kidney disease (CKD), and type 2 diabetes.

Selective generation of reactive oxygen species in plasma activated water using CO2 plasma [PDF]

arXiv, 2022
In the present work, a process of a selective generation of reactive oxygen species (ROS) such as H2O2 and dissolved O3 in plasma-activated water (PAW) is discussed. For selective ROS generation, pure CO2 was used as a plasma-forming gas. The gases species present in plasma and properties of PAW are compared in details when CO2 and air are used as ...
