The association between health literacy, private health insurance, and medical expenditure in South Korea.

Background: Health literacy (HL) is crucial for effective healthcare utilization, but its relationship with private health insurance (PHI) enrollment and medical expenditure in South Korea remains unexplored.

Objectives: This study aimed to examine the associations between HL, PHI enrollment, and annual out-of-pocket (OOP) medical expenditure in South Korea's universal healthcare system.

Methods: Using data from the 2021 Korea Health Panel Study, we analyzed 5,469 participants aged 19-65.

Actinomycetes studies in Tunisia.

Tunisia, located in North Africa, has a diverse topography along the Mediterranean Sea to the Sahara Desert. These environments encompass oases, rhizosphere soils, desert deposits, saline wetlands, offshore oilrigs, and ancient monument rocks. The country's varied environments have led to the isolation of a multitude of actinomycetes.

Comparison of clinical outcomes between conventional and underwater endoscopic mucosal resection for duodenal neuroendocrine tumors.

Duodenal neuroendocrine tumors are relatively rare subepithelial tumors that arise from cells of the neuroendocrine system. Small duodenal neuroendocrine tumors can be treated endoscopically because of their low potential for metastasis. This study aimed to evaluate the clinical outcomes of conventional and underwater endoscopic mucosal resection for duodenal neuroendocrine tumors.

Circulating apelin levels fail to link sarcopenia-related muscle parameters in older adults.

Background: Based on the compelling experimental evidence supporting apelin's beneficial effects on muscle metabolism, our study aimed to evaluate the role of circulating apelin levels as a biomarker for muscle health in humans.

Methods: This investigation employed a cross-sectional design, encompassing 237 community-dwelling older adults aged ≥65 years who underwent comprehensive geriatric evaluations in South Korea. Sarcopenia diagnosis was based on Asian-specific criteria, and serum apelin concentrations were determined using enzyme immunoassay techniques.

Recent Developments in Plastic Deformation Behavior of Titanium and Its Alloys During the Rolling Process: A Review.

Titanium (Ti) and its alloys are used in various applications, including aircraft frames, ship parts, heat exchangers, and evaporator tubes, because of their extraordinary properties, such as high specific strength, excellent corrosion resistance at high temperatures, good castability, and weldability. Plastic deformation plays a crucial role in securing the appropriate microstructure and strength of Ti and alloys in these applications. The rolling process, one of the most useful methods for plastic deformation, causes efficient deformation inside the materials, resulting in grain refinement, dislocation slip, and twinning.
