Molecular Oncology, EarlyView.Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Accessing brain magnetic resonance imaging (MRI) can be challenging, especially for underserved patients, which may lead to disparities in neurological diagnosis. Method This mixed‐methods study enrolled adults with one of four neurological disorders: mild cognitive impairment or dementia of the Alzheimer type, multiple sclerosis ...

The Turkish Journal of Pediatrics, 2017 Arthrogryposis-renal dysfunction-cholestasis (ARC) is an autosomal recessive multisystem disorder characterized by arthrogryposis, renal tubular dysfunction and neonatal cholestasis with low gamma glutamyl transpeptidase activity. Most of the mutations in ARC syndrome are associated with the vacuolar protein sorting 33B (VPS33B) gene on chromosome ...

An investigation of arc discharging on negatively biased dielectric conductor samples in a plasma [PDF]
, 1985 Proposals are now being developed for the construction of high-power photovoltaic systems for operation in low Earth orbit, where the plasma number density is about 1,000 to 1,000,000 per cubic cm.

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Improved Mathematical Model for a Single-Ground Arcing Fault in Medium Voltage Distribution Networks
CSEE Journal of Power and Energy SystemsMedium voltage distribution networks usually suffer from single-ground arcing fault, especially high impedance arcing fault. Moreover, induced intermittent arcing faults can severely endanger the reliability and safety of power systems.

Arc erosion characteristics of DC contactor contacts
电力工程技术, 2023 The arc is generated upon contact breaking-off resulting in surface erosion in the terminals and affecting the performance of electrical contact. As there is no natural zero crossing point in the DC power supply system, the erosion caused by arcs is ...

Advanced Engineering Materials, EarlyView.This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...
