SDPR–STK38 axis controls the proliferation–differentiation balance in alveolar type II cells

Animal Models and Experimental Medicine, EarlyView.
The present study identifies SDPR as a pivotal regulator orchestrating the balance between proliferation and differentiation in alveolar type II (AT2) cells. In SDPR+/+ cells, SDPR binds to and inhibits STK38 activity, thereby sustaining GSK‐3β signaling functionality to promote cyclin D1 degradation and maintain cell cycle homeostasis.

Therapeutic Applications of Stimuli‐Based Release and Engineering of Extracellular Vesicles

Advanced NanoBiomed Research, EarlyView.
This review summarizes the effects of endogenous and exogenous stimuli, their effects on the natural release of extracellular vesicles, as well as their uptake and release. It also gives an overview of stimuli‐responsive EVs and their therapeutic applications. Extracellular vesicles (EVs), nano‐ to microsized lipid bilayer membrane‐bound particles, are

Fast transient simulation of fernandez surge arrester model on a transmission line using ATP [PDF]

, 2015
Lightning is a very impressive phenomenon that occurs in nature. The amount of energy contained in a lightning stroke is very high and it can be extremely destructive. Electric distribution networks are particularly vulnerable to lightning strokes.

Optimized Selenium‐Doped Nanocomposites for Enhanced Polymer Gel Performance in Permeability Reduction

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Excessive water production in mature oil fields necessitates robust shut‐off treatments, yet conventional polymer gels often fail under high‐temperature and high‐salinity conditions. This study aims to enhance gel thermal stability and mechanical strength by incorporating selenium‐doped Ag/AgO–ZnO nanocomposites synthesized via a novel green ...

Synergistic Physicochemical Inhibition of Reactive Shale Formations Using Hydrothermally Synthesized Hydroxyapatite Nickel Tungstate Nanocomposites in Water‐Based Drilling Fluids

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Wellbore instability driven by the volumetric expansion of reactive shale formations remains a primary operational challenge in modern drilling engineering, causing severe mechanical failures and substantial economic deficits. The objective of this study is to formulate and evaluate a novel dual‐action chemical additive capable of ...

Optimization of zinc oxide surge arrester design in reducing leakage current / Nurul Ain Abdul Latiff [PDF]

, 2018
A surge arrester diverts lightning surge to earth, preventing damage on electrical systems. Under normal operating condition, surge arresters do not conduct current but there is a leakage current flow across surge arresters. Leakage current is one of the
