Unveiling protective mechanisms of wild olive (acebuche) oil in retinal pigment epithelial cells with hypertensive phenotype

The Journal of Physiology, EarlyView.
Abstract figure legend Circulating extracellular vesicles (EVs) derived from acebuche (ACE) oil‐ and extra virgin olive oil (EVOO)‐fed mice modulate nitric oxide (NO) metabolism in the retinal pigment epithelial cell line (ARPE19) with a hypertensive phenotype induced by angiotensin II (AngII).

Methodological Applicability of Ultra-Low Background Liquid Scintillation Counters in Low-Level Tritium Measurement

Applied Sciences
Tritium (3H) is a low-energy β emitter commonly found in environmental water samples, and its routine monitoring requires highly sensitive techniques capable of achieving low detection limits.

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

Atom 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

Guanidinium Like‐Charge Ion Pairing and Oligoarginine Aggregation in Water by Nuclear Magnetic Resonance, Cryo‐Electron Microscopy, and Molecular Dynamics

Aggregate, Volume 7, Issue 2, February 2026.
This study shows that guanidinium cations weakly attract one another in water and form like‐charge contact ion pairs. From NMR, we determine the free energy of ion‐pair formation to be ≈${\approx }$ –0.5 kJ mol−1${\rm mol}^{-1}$, consistent with all‐atom MD simulations and DFT calculations.

Advances in Kinetic Isotope Effect Measurement Techniques for Enzyme Mechanism Study

Molecules, 2013
Kinetic isotope effects (KIEs) are a very powerful tool for investigating enzyme mechanisms. Precision of measurement is the most important factor for KIE determinations, especially for small heavy atom KIEs.

Time-Resolved Liquid Scintillation Counting [PDF]

Radiocarbon, 1990
Historically, scientists who perform low-level measurements of 14C for age dating, and 3H2O for environmental contamination, have purchased or constructed highly specialized instruments to quantitate low-level radionuclides using a general-purpose liquid-scintillation analyzer (LSA).

Astrocyte MCT1 Expression Does Not Contribute to the Axonal Degenerative Phenotype Observed With Ubiquitous MCT1 Depletion

Glia, Volume 74, Issue 2, February 2026.
Loss of astrocytic MCT1 does not cause late onset neurodegeneration. As ubiquitous MCT1 deletion causes axonal degeneration, oligodendrocytes and potentially other cells are more prominent drivers of MCT1‐mediated metabolic support of neurons. ABSTRACT We recently reported that the loss of oligodendrocyte metabolic support through the lactate and ...
