In the experimental determination of activity of low gamma energy emitters by HPGe spectrometry, after cyclotron irradiation of thick targets of high Z elements, it is mandatory to introduce a correction for gamma-ray self-absorption in the target. The amount of this correction is substantial in order to provide a statistically acceptable agreement with the thick-target-yield data obtained by integration of the experimental thin-target-yield data that are very slightly affected by self-absorption instead.

Background: Osteoporosis, a frequent complication of gastrectomy, increases with age, and the average age of gastric cancer patients continues to rise. This study aims to analyze perioperative factors of osteoporosis after radical gastrectomy.
Materials And Methods: This retrospective cohort study included patients who underwent dual-energy-X-ray absorptiometry after gastrectomy due to gastric cancer between 2016 and 2019 at Seoul Boramae Medical Center.

Malaria, a parasitic disease caused by Plasmodium spp. and transmitted by Anopheles mosquitoes, remains a major global health issue, with an estimated 249 million cases and 608,000 deaths in 2022. Rapid and accurate diagnosis and treatment are crucial for malaria control and elimination.

Background: The link between regional body fat distribution and overactive bladder (OAB) in prior epidemiological research has been uncertain. Our objective is to assess the relationship between increased regional body fat and the prevalence of OAB.
Methods: Within this analysis, 8,084 individuals aged 20 years and older were selected from NHANES surveys conducted from 2011 to 2018.
Micromodification in bulk undoped polymethylmethacrylate (PMMA) by single focused (numerical aperture (NA) = 0.25), 1030-nm 250-fs laser pump pulses was explored by pump self-transmittance; optical, 3D-scanning confocal photoluminescence (PL); Raman micro-spectroscopy; and optical polarimetric and interferometric microscopy. Starting from the threshold pulse energy = 0.
