Liquid scintillation counting for 14C uptake of single algal cells isolated from natural samples

open access: yes, 1981
Short term rates of /sup 14/C uptake for single cells and small numbers of isolated algal cells of five phytoplankton species from natural populations were measured by liquid scintillation counting.

Systemic aging fuels heart failure: Molecular mechanisms and therapeutic avenues

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1059-1080, April 2025.
Abstract Systemic aging influences various physiological processes and contributes to structural and functional decline in cardiac tissue. These alterations include an increased incidence of left ventricular hypertrophy, a decline in left ventricular diastolic function, left atrial dilation, atrial fibrillation, myocardial fibrosis and cardiac ...

Application of Digital Anti-Coincidence Counting Method for Primary Activity Determination of 59Fe

open access: yesAtom Indonesia, 2019
As a radiopharmaceutical, the use of 59Fe is classified as a high pharmaceutical risk product. Therefore, a standard reference for activity measurement of 59Fe is necessary to ensure its metrological aspect. This paper describes an alternative method for

Glial Versus Neuronal Na+/K+‐ATPase in Activity‐Evoked K+ Clearance and Their Sensitivity to Elevated Extracellular K+

open access: yesGlia, EarlyView.
The glial Na+ pump regulates [K+]o during neuronal activity, and the neuronal version restores [K+]o to baseline. Spreading depression‐related rise of K+ does not cause SD propagation via suppression of Na+/K+‐ATPase or glutamate transport. ABSTRACT Neuronal activity in the central nervous system is associated with a [K+]o transient that is swiftly ...

Tritium radioactivity estimation in cement mortar by heat-extraction and liquid scintillation counting

open access: yesNuclear Engineering and Technology, 2021
Tritium extraction from radioactively contaminated cement mortar samples was performed using heating and liquid scintillation counting methods. Tritiated water molecules (HTO) can be present in contaminated water along with water molecules (H2O).

In Vitro and Clinical Evaluations of UGT1A1‐, P‐gp‐, OATP1B1‐, and BCRP‐Mediated Drug–Drug Interactions of Belumosudil, a Potent ROCK2 Inhibitor

open access: yesThe Journal of Clinical Pharmacology, EarlyView.
Abstract Belumosudil is an oral selective rho‐associated coiled‐coil containing protein kinase 2 inhibitor, approved as a treatment for chronic graft‐versus‐host disease. Prior clinical studies demonstrated that coadministration with strong CYP3A4 inducers or proton pump inhibitors requires dose modification of belumosudil.

A simple method for calibration of Lucas scintillation cell counting system for measurement of 226Ra and 222Rn

open access: yesJournal of Radiation Research and Applied Sciences, 2014
Known quantity of radium from high grade ore solution was chemically separated and carefully kept inside the cavity of a Lucas Cell (LC). The 222Rn gradually builds up and attain secular equilibrium with its parent 226Ra.
