Unexpected Oil Cyst Formation Following Lower Blepharoplasty Despite Adinizer-Assisted Microfat Grafting: Limitations of Fat Particle Size Reduction

Oil cyst formation after periocular autologous fat grafting is infrequently reported but represents a clinically relevant complication because it may present as a palpable mass and mimic other eyelid lesions. Various fat-processing techniques, including mechanical microfragmentat...

Specialty-aware benchmark design, split integrity, and baseline evaluation for Korean medical question answering

Korean medical question answering requires evaluation resources that reflect local terminology, clinical specialty structure, and essential-care priorities. We characterized the AI Hub Specialized Medical Knowledge and Essential Medical Knowledge datasets, audited the independenc...

Sensitivity of municipal heatwave vulnerability assessment to population density: Urban-rural spatial shifts in South Korea

As heatwaves become an increasingly recurrent hazard, accurate assessment of local heatwave vulnerability has become increasingly important. This study examined the sensitivity of the heatwave vulnerability index to the inclusion of population density in terms of entropy weights,...

Association of Estimated Arterial Stiffness with Collateral Status and Functional Outcome after Endovascular Thrombectomy: A Secondary Analysis of the OPTIMAL-BP Trial

PURPOSE: Estimated pulse wave velocity (ePWV) is a surrogate of arterial stiffness that may influence stroke outcomes and potentially affect collateral circulation. We examined the association of ePWV with collateral status and 3-month functional outcome after successful endovasc...

Prioritising Content for Continuing Education in Non-Invasive Ventilation Care: A Needs Assessment Survey of Intensive Care Unit Nurses

Background: The success of non-invasive ventilation (NIV) depends on bedside nursing judgement, yet nurses report insufficient preparation, and educational content is usually decided before the competencies nurses most need are identified. Objectives: To prioritise NIV competenci...

Surface-Mediated Immunomodulation by Electrostatic Immobilization of Naproxen on Plasma-Aminated Poly(ε-caprolactone) Films Rescues Osteogenic Differentiation via Attenuation of NF-κB Signaling

Abstract Chronic inflammation following biomaterial implantation often leads to fibrous encapsulation and compromised osseointegration, particularly in clinically inflamed environments. We developed a surface-functionalized poly(ε-caprolactone) (PCL) platform to modulate the earl...

Tungsten Oxide-contained PEO Coatings on Ti–6Al-4 V Alloys: Enhanced Surface Characteristics and Bioactivity for Bio-implant

Abstract This study presents a novel approach to enhance the multifunctionality of Ti–6Al-4 V alloys for bio-implant surfaces by integrating tungsten oxide (WO3) nanoparticles with hydroxyapatite (HA) through dual-stage processing: direct incorporation during plasma electrolytic...

Nanolayer-Confined Strain Waves in Femtosecond-Optical-Vortex-Excited Multiferroic BiFeO3

Abstract Strain waves provide a route to reshape nanoscale order in functional materials, where lattice deformation couples to charge and spin degrees of freedom. Real-space tracking of these transient strain fields is critical for connecting acoustic excitation to functionality,...

Continuous Measurement of Spatially Resolved Red Blood Cell Aggregation Using Multiple Side-Branch Channels

Red blood cell (RBC) aggregation is an important hemorheological property that influences blood viscosity, microcirculation, and stored-blood quality. However, conventional measurements commonly require repeated flow cessation or flow-rate modulation, limiting continuous monitori...

Multivariate Characterization of Gait Variability Under Simulated Ship Roll Motion

Walking on a ship requires continuous adaptation to a support surface that changes orientation with vessel motion. However, conventional group-level and joint-by-joint analyses may not characterize the coordinated structure of this adaptation or the heterogeneity of individual re...

An Augmented reality-based guidance system for botulinum toxin injection development and validation study

This paper presents a training-oriented AR system prototype for face-attached visualization of facial BoNT injection planning, and reports a controlled validation of its image-plane overlay accuracy and usability. The prototype was implemented on Android devices using Unity3D wit...

Systematic evaluation of smart-farm-grown Anthriscus sylvestris leaf extracts for antioxidant and anti-melanogenic activities

Anthriscus sylvestris (wild chervil) leaf extracts represent a promising natural resource for cosmeceutical biotechnology applications. This study systematically evaluated polarity-based extracts, including hot water, 40%, 70%, and 100% ethanolic extracts, and an ethyl acetate fr...

Recent Advances in Glucagon-Like Peptide-1 Receptor and Melanocortin-4 Receptor Agonists for the Treatment of Obesity and Type 2 Diabetes

Abstract The global rise in aging populations has been accompanied by increasing rates of obesity and type 2 diabetes, both of which pose significant public health and economic challenges. This review aims to investigate the pathophysiological link between obesity and diabetes an...

Factors Associated with a Disposition-Based Indicator of Severe Injury Among Older Adults with Fall-Related Injuries: A Secondary Analysis of the 2023 Emergency Department-Based Injury In-Depth Surveillance

Background/Objectives: Falls are a major cause of injury-related morbidity and mortality among older adults. This study aimed to examine factors associated with a disposition-based indicator of severe injury among older adults with fall-related injuries using data from the 2023 E...

Leakage-Resistant Evaluation of Gait Mat and Multisensor Biomechanical Features for Knee Osteoarthritis Screening: A Subject-Level Data Integrity Study

Selecting a sensing architecture for knee osteoarthritis (OA) screening requires balancing biomechanical information, system complexity, and reproducibility. We audited a public Korean multimodal gait dataset and performed a leakage-resistant internal evaluation. The release cont...
