Postoperative Stress Accelerates Atherosclerosis Through Inflammatory Remodeling of the HDL Proteome and Impaired Reverse Cholesterol Transport

Advanced Science, EarlyView.
The study shows that noncardiac surgical inflammation rapidly disrupts HDL function and cholesterol efflux in mice and human patients. Impaired reverse cholesterol transport after surgery drives rapid lipid accumulation, NETosis, and apoptosis within atherosclerotic plaques.

Influence of natural radium contamination of barium chloride on the determination of radium isotopes in the water samples using α/β liquid scintillation spectrometry

Nukleonika, 2016
The determination of radium isotopes in drinking water by liquid scintillation technique requires some reagents that are used for separating radium from water samples. One of the main reagents is BaCl2·H2O.

Separation and degradation detection of nanogram-per-litre concentrations of radiolabelled steroid hormones using combined liquid chromatography and flow scintillation analysis

Scientific Reports, 2020
Detection of micropollutants such as steroid hormones occurring in the aquatic environment at concentrations between ng/L and µg/L remains a major challenge, in particular when treatment efficiency is to be evaluated.

An Advanced Optimization Method to Minimize the Detection Limit of Liquid Scintillation Counter to Measure Low-Level Tritium Activity in Groundwater

Radiation, 2023
In arid regions, the tritium concentration in groundwater is typically very low and often falls below the minimum detectable activity (MDA) of the conventional liquid scintillation counter (LSC).

Direct measurement of carbon-14 in carbon dioxide by liquid scintillation counting [PDF]

, 1969
Liquid scintillation counting technique is applied to the direct measurement of carbon-14 in carbon dioxide. This method has high counting efficiency and eliminates many of the basic problems encountered with previous techniques.

Arginine Methylation Antagonizes TEAD3‐Mediated Repression to Promote Osteogenic Differentiation by Disrupting RUNX2‐Sequestrating Condensates

Advanced Science, EarlyView.
In the unmethylated state, TEAD forms stable, repressive condensates that sequester the osteogenic master regulator RUNX2. Arginine methylation of TEAD at R55 acts as a molecular brake, dissolving these condensates to release RUNX2 and activate the osteogenic program.

Direct determination of lead-210 by liquid-scintillation counting [PDF]

, 1969
Soft betas, the internal conversion electrons, and unconverted gamma rays from lead-210 are efficiently detected in a liquid scintillation counting system with efficiency of 97 percent. The counter is interfaced with a multichannel pulse height analyzer.

The percutaneous absorption of soman in a damaged skin porcine model and the evaluation of WoundStat™ as a topical decontaminant [PDF]

, 2017
PURPOSE: The aim of this study was to evaluate a candidate haemostat (WoundStat™), down-selected from previous in vitro studies, for efficacy as a potential skin decontaminant against the chemical warfare agent pinacoyl methylfluorophosphonate (Soman, GD)

Halide‐Exchange Arrest Enables Reabsorption‐Free CsPbCl3/CsPbI3 Perovskite Core/Shell Nanocrystals

Advanced Science, EarlyView.
Achieving large Stokes shifts in perovskite nanocrystals is challenging due to halide mobility that disrupts stable core–shell structures. Using CdCl2 passivation, this work stabilizes CsPbCl3/CsPbI3 heterostructures, yielding a ≈1.2 eV Stokes shift, high quantum yield, and fast exciton transfer, enabling reabsorption‐free emitters for advanced ...
