Action and immunomodulatory mechanisms, formulations, and safety concerns of probiotics.

The global probiotics market has been continuously growing, driven by consumer demand for immune-enhancing functional foods, dietary supplements, and natural therapeutics for gastrointestinal and gut function-mediated diseases. Probiotic microorganisms represent a diverse group of strains with complex but generalized mechanistic patterns. This review describes the various immunomodulatory mechanisms by which probiotics exert their effects, including the competitive exclusion of pathogenic microbes, production of antimicrobial substances, modulation of the immune system, and improvement of gut barrier function.

Bound-State Beta Decay of ^{205}Tl^{81+} Ions and the LOREX Project.

Stable ^{205}Tl ions have the lowest known energy threshold for capturing electron neutrinos (ν_{e}) of E_{ν_{e}}≥50.6  keV. The Lorandite Experiment (LOREX), proposed in the 1980s, aims at obtaining the longtime averaged solar neutrino flux by utilizing natural deposits of Tl-bearing lorandite ores.

Thermal Softening Measurements of Refractory High-Entropy Alloys.

Home-built equipment will be presented able to measure the thermal expansion (with a flat indenter) and indentation depth (with a pointed indenter) up to 1100 °C. In dilatometer mode, the allotropic phase transformations can be studied. For hardness, a Rockwell-type measurement is adopted.

Different PSMA Radiopharmaceuticals: A Comparative Study of [F]F-PSMA-1007, [F]F-JK-PSMA-7, and [Tc]Tc-PSMA-I&S in the Skeletal System.

Background: Numerous PSMA-based tracers are used for diagnostic prostate cancer imaging, but comprehensive comparisons between multiple ligands are lacking. This study aimed to compare physiological skeletal uptake and tracer uptake in commonly recommended PSMA reference regions across three different PSMA ligands in prostate cancer patients.

Methods: A total of 281 prostate cancer patients were included.
