Shape-Controlled Poly(N-isopropylacrylamide) Actuators Enabled by Tensile-Stress Mismatch for Temperature-Adaptive Textiles

Thermal comfort is a key determinant of human health and requires adaptive responses to dynamic environments. Here, we report a temperature-adaptive textile enabled by a tensile stress mismatch-driven poly(N-isopropylacrylamide) (PNIPAM) actuator operating within a human-friendly...

Biomaterial-Based Magnetic Nanobiochar for Remediation of Trichloroethylene: Environmental Fate, Toxicity, Mechanistic Insights, and Technological Advancements

Trichloroethylene (TCE) is a carcinogenic, persistent groundwater contaminant against which conventional remediation techniques like pump-and-treat, soil vapor extraction, and chemical oxidation falter badly especially at dense non-aqueous-phase-liquid (DNAPL) source zones. Magne...

Execution Feasibility and Limits to Arbitrage: High‐Frequency Evidence From KOSPI 200 Box Spreads

ABSTRACT This study examines whether apparent box‐spread mispricing in the KOSPI 200 index options market translates into execution‐feasible arbitrage after realistic implementation frictions are imposed. Using high‐frequency trade‐and‐quote data from the Korea Exchange, we const...

Antimony-contact MoS2 FET gas sensors for reinforcement-learning–driven hazard perception at room temperature

Two-dimensional van der Waals semiconductors promise low-power chemical perception at room temperature, yet contact-limited on-currents and slow recovery impede closed-loop decision making in hazardous environments. Here we propose antimony (Sb)-contact two-dimensional (2D) monol...

Integrative molecular pathology of sudden cardiac death associated with ARVC-like cardiomyopathy in a Western Lowland Gorilla

Abstract Background Cardiovascular disease is a major cause of morbidity and mortality in captive great apes, however, the molecular basis of sudden cardiac death (SCD) in gorillas remains poorly characterized. In particular, few studies have integrated histopathology with genomi...

Frailty status, but not physical activity volume, is associated with chronic disease, self-reported memory difficulty, and depressive mood in older Korean adults: a cross-sectional analysis of the 2019 Korea National Health and Nutrition Examination Survey

Frailty in older adults increases vulnerability to chronic diseases, cognitive complaints, and depressive symptoms. Studies in Korean older adults have typically combined frailty status and physical activity into composite groupings that do not separate their associations. Low ph...

Metabolic health, obesity, and prognosis in chronic obstructive pulmonary disease

Metabolic syndrome is a common comorbidity in chronic obstructive pulmonary disease (COPD), yet its long-term impact on survival and exacerbations remains controversial. We investigated whether metabolic health status and body mass index (BMI) influence mortality and the rate of...

Salvage Surgery Including Rectal Wall Vas Deferens Pexy for Recurrent Bilateral Perineal Hernia with Bladder Retroflexion in a Dog: A Case Report

Bladder retroflexion associated with perineal hernia may cause urinary dysfunction, and surgical correction can be challenging after repeated procedures because of extensive adhesions and altered anatomy. An 11-year-old, 7.5 kg, castrated male Pomeranian was referred for recurren...

Intrinsically Bioactive Tannic Acid-Grafted Succinoglycan for Self-Healing and Stimuli-Responsive Drug Delivery Hydrogels

Tannic acid grafting provides a practical strategy for introducing bioactive phenolic functionality into microbial polysaccharides for multifunctional hydrogel design. Herein, tannic acid-modified succinoglycan (SG-TA) was prepared through an ascorbic acid/ H2O2-mediated free-rad...

Pepsinogen Assay Findings in Individuals With Gastric Atrophy and Intestinal Metaplasia

Serum pepsinogen (PG) testing is widely used as a non-invasive biomarker for gastric atrophy; however, its clinical interpretation varies depending on the severity and distribution of gastritis as well as on the assay methods. Autoimmune gastritis is characterized by markedly dec...

Carcinoma of Unknown Primary Origin Presenting as Rapidly Progressive Multifocal Skeletal Lesions and Fatal Systemic Thrombosis in a Dog: A Case Report

Carcinoma of unknown primary origin (CUP) involving the skeletal system is rare in dogs and may closely mimic primary bone neoplasia or multicentric lymphoma, creating substantial diagnostic challenges. A 15-year-old spayed female Jindo-mix dog was referred for rapidly progressiv...

Impact of operon architecture on metabolic flux: highlighting gene arrangement as a critical factor for flavonoid O-rhamnoside synthesis

Abstract Background dTDP-rhamnose is synthesized by four genes ( rfbBDAC ) in Escherichia coli . While reconfiguring this operon could potentially enhance biosynthetic yields, precisely quantifying intracellular dTDP-rhamnose levels remains technically challenging. In this study,...

Plasma‐Engineered Polyethylene‐Reinforced Anion Exchange Membranes With Low Ionic Resistance and Low Hydrogen Crossover for Water Electrolysis

ABSTRACT Anion exchange membrane water electrolysis (AEMWE) enables low‐cost green hydrogen production but remains limited by the delicate balance among ionic resistance, gas crossover, and mechanical durability in hydrocarbon‐based membranes. Although reinforced composite membra...

Energy Substrate Utilization and Body Composition Following Exercise Preconditioning During Alternate-Day Fasting and Concurrent Exercise in Mice

Background/Objectives: Alternate-day fasting (ADF) combined with exercise has been suggested as an effective lifestyle strategy for reducing fat mass while preserving lean mass. However, whether exercise preconditioning before ADF plus concurrent exercise affects subsequent body-...

Domain-Specific Cognitive Concordance in Older Married Couples

Importance Spousal similarity in late-life cognition has been reported, but whether concordance differs across cognitive domains remains unclear. Objective To examine whether cognitive concordance among older married couples is domain specific by comparing real couples with demog...

Quantum‐Trained AI Enables Inverse Design of Organic Frontier Orbitals at Billion‐Scale

ABSTRACT Frontier orbital energies govern charge transfer, energy‐level alignment, and optoelectronic performance in organic molecules, yet their prediction across vast chemical spaces remains challenging because they arise from coupled effects of functionality, conjugation, and...

AGV: a web-based visualization tool for reconstructed ancestral genomes

The ancestral genome is the genome of the common ancestor of extant species. Ancestral genome reconstruction infers evolutionary events from extant genomes to recover the genomic states of extinct ancestors. Although this approach provides a powerful framework for studying genome...

PHGDH inhibition overcomes dabrafenib resistance through metabolic rewiring in BRAF V600E anaplastic thyroid carcinoma

Abstract Dabrafenib, a BRAF kinase inhibitor, is used clinically to treat anaplastic thyroid carcinoma (ATC) harboring the BRAF V600E mutation. However, its clinical efficacy is limited due to the rapid emergence of resistance to treatment. In this study, we established a dabrafe...

Lipopolysaccharide priming confers trained immunity and enhances antiviral defense against Sendai virus via STAT1/2 signaling

Trained immunity, the functional reprogramming of innate immune cells that enhances responses to secondary challenges, represents a paradigm shift in our understanding of immune memory. We investigated whether lipopolysaccharide (LPS) priming could induce trained immunity against...
