Background: /L. Methods: Precision of WBC quantification in the two modes was evaluated using four samples according to the European Federation of Clinical Chemistry and Laboratory Medicine (EFLM) criterion (CV% 5.6). Linearity was evaluated at five concentrations. The two modes...

Perspectives on Community-Based Pediatric Obesity Prevention and Management Programs in South Korea: A Qualitative Interview Study of School and Local Public Health Center Providers

Background: Pediatric obesity has increased globally, and South Korea has reported the highest prevalence in East Asia. Despite national policies addressing children's nutrition and health, fragmented governance and overlapping programs may limit their effectiveness. We compared...

PRISM: Probabilistic Trajectory Prediction of Non-Cooperative Aerial Objects for Risk-Aware Path Planning in Urban Air Mobility Operations

Urban air mobility path planning must account for objects that do not provide cooperative surveillance information, but their motion and avoidance responses vary by class, making a single extrapolated trajectory insufficient to inform every path decision. We propose PRISM to brin...

Experimental and numerical investigation of PCM-based cylindrical heat sinks with radially oriented fins under transient high-power loads

Phase change material (PCM)-based heat sinks buffer intermittent thermal loads, but the heating-to-solidification response of cylindrical heat sinks with radially oriented fins remains insufficiently quantified. This response was characterized experimentally, while validated simu...

Long-Term Outcomes According to a Device-Assisted Enteroscopy Strategy after Capsule Endoscopy in Patients with Small Bowel Bleeding: A Nationwide Population-Based Cohort Study

Background/Aims: Although the use of device-assisted enteroscopy (DAE) has increased, few large-scale studies have examined long-term outcomes focused on small bowel (SB) bleeding. We analyzed National Health Insurance Service data to evaluate the clinical utility of DAE in patie...

Lymphocyte-predominant inflammation refines lung histopathology scoring in preclinical respiratory viral infection: support from deep learning analysis

Respiratory viral infections such as influenza and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) remain major causes of morbidity and mortality. Although lung histopathology is a major endpoint in preclinical studies, conventional H&E-based grading primarily evalua...

Targeting EGR1 Attenuates CCL2 Expression in Inflammatory Keratinocytes and Allergic Skin Inflammation

Early growth response 1 (EGR1) is a zinc-finger transcription factor involved in inflammatory gene regulation, but the extent to which pharmacological inhibition of EGR1 DNA-binding activity influences inflammatory transcriptional responses in keratinocytes remains incompletely u...

Interface-Programmed Growth of High-Aspect-Ratio 1D Ni–MOF Nanofibers on MXene for Wearable Enzyme-Free Glucose Sensing

Abstract Noninvasive wearable glucose sensors capable of real-time sweat analysis offer a less discomforting alternative for long-term monitoring in patients with diabetes. However, practical implementation remains challenging. Major barriers include insufficient catalytic sensit...

Identification and Characterization of a Previously Uncharacterized Metagenome-Derived Chitinase and Its Application in N -Acetyl- d -Glucosamine Production from Crayfish Shell Waste

Abstract The generation of agricultural and food-processing byproducts has increased rapidly, highlighting the importance of their high-value utilization. In this study, a putative chitinase gene was identified from a metagenome-assembled genome. The enzyme plays a key role in ch...

Effects of speech-enabled LLM-based chatbots on L2 learning outcomes and affective domains: a multilevel meta-analysis

Abstract Recent developments in natural language processing and automatic speech recognition have significantly advanced chatbot communication using the voice mode, establishing these tools as viable resources for L2 speaking practice. More recently, the L2 chatbot domain has lev...

Pathways from adverse childhood experiences to parenting competence: the roles of cognitive emotional regulation and social support

These findings suggest that strengthening adaptive CER may be particularly effective for mothers with higher levels of social support. For those with lower levels of social support, the first priority should be enhancing social support to lay the groundwork for emotional regulati...

Evaluation of surface roughness, microhardness, staining, and antimicrobial properties of zinc oxide–coated orthodontic thermoformed retainers – an in vitro study

Vacuum-formed retainers (VFRs) are the most commonly used removable orthodontic retention appliances owing to their esthetics, comfort, and ease of fabrication. However, they are prone to discoloration, microbial colonization, and reduced mechanical durability when used intraoral...

Multiple introductions and spread of novel reassortant highly pathogenic avian influenza A (H5N1) clade 2.3.4.4b viruses via wild birds, South Korea, 2024–2025

Abstract Between 14 October 2024 and 24 March 2025, 43 cases of clade 2.3.4.4b highly pathogenic avian influenza (HPAI) type A (H5N1) infections in wild birds and 1 case in a leopard cat were detected through the national HPAI surveillance program. We performed whole-genome seque...

Comparative immunogenomics of Suidae reveals lineage-specific immune gene disruption and positive selection

Understanding the evolutionary dynamics of immune-related (IR) genes among closely related species provides key insights into lineage-specific adaptations to pathogens. The family Suidae is a powerful model for investigating immune gene evolution owing to its broad ecological div...

Criteria-based probable REM sleep behaviour disorder and risk of Lewy body dementia: analyses of a memory clinic cohort and a community cohort

Abstract Background REM sleep behaviour disorder (RBD) is the strongest prodromal marker of alpha-synucleinopathies, but whether a brief questionnaire carries prognostic information for Lewy body dementia is unclear. We tested whether criteria-based probable RBD (pRBD)—a question...

Long-term lactate ingestion and exercise training differentially modulate body composition, resting substrate metabolism, and tissue-specific metabolic remodeling in mice

[Purpose] This study investigated whether long-term lactate ingestion induces systemic and tissue-specific metabolic adaptations under normal physiological conditions and whether these responses differ from those induced by exercise training.[Methods] Thirty-two male mice were ra...

A complementary amino acid formulation enhances exercise-induced skeletal muscle remodeling during resistance training

[Purpose] This study investigated whether a five-amino-acid formulation integrating complementary anabolic, metabolic, and redox-supporting functions enhances skeletal muscle remodeling during resistance training.[Methods] Male C57BL/6N mice were assigned to eight groups receivin...

PS7-21. Interaction Between Growth Stage of Pigs and Soluble Dietary Fiber-to-insoluble Dietary Fiber Ratio for Ileal Digestibility and Hindgut Disappearance of Energy and Nutrients.

Abstract Nursery pigs have relatively underdeveloped digestive and absorptive capacities. As pigs grow, the hindgut continues to develop and fiber fermentation occurs mostly in the hindgut. Fibers are partitioned into soluble and insoluble portions. Soluble dietary fiber (SDF) an...

Repair of a Large Congenital Peritoneopericardial Diaphragmatic Hernia with Canine Small Intestinal Submucosa Patch Reinforcement in a Dog: A Case Report

Peritoneopericardial diaphragmatic hernia (PPDH) is a congenital anomaly allowing communication between the peritoneal and pericardial cavities. Surgical repair of large diaphragmatic defects can be challenging due to insufficient tissue for primary closure. A 2-year-old intact f...

Tip-Sonication-Induced Dilute Alloying of Metal Pairs with Limited Bulk-Immiscibility

Alloying metals with unfavorable bulk mixing thermodynamics remains challenging because conventional synthesis often favors elemental segregation rather than compositionally mixed nanoparticles. This study aimed to determine whether direct tip sonication can promote compositional...
