Dual antidiabetic potential of arjunglucoside I and arjunetin from Terminalia chebula via modulation of insulin- and gluconeogenesis-related responses

A deciduous tree belonging to the Combretaceae family, Terminalia chebula Retz. has a long history of traditional use in diabetes management. However, it is not fully understood how the extract of T. chebula exerts the antidiabetic effects. To identify the constituents responsibl...

CT–measured diaphragmatic crus cross-sectional area and its association with short-term outcomes in acute exacerbations of COPD

Risk stratification for acute exacerbations of chronic obstructive pulmonary disease (AECOPD) in the emergency department (ED) is challenging. Conventional scoring systems, such as the Ottawa COPD Risk Scale (OCRS) and the Dyspnea, Eosinopenia, Consolidation, Acidemia, and Atrial...

A Stretchable Organic Electrochemical Transistor Mechano‐Synapse With Biomimetic Mechanotransduction for Intelligent Soft Electronic Skin

ABSTRACT Tactile perception relies on early preprocessing of signals from adapting afferents; in particular, synapse‐like coupling between afferent nerve fibers and adapting mechanoreceptors supports transduction and sensory memory, enabling efficient central representations of t...

Risk of peripheral artery disease following ankylosing spondylitis, 2012–2023: a nationwide cohort study in South Korea

OBJECTIVE: Ankylosing spondylitis (AS) is a chronic inflammatory disease linked to systemic vascular complications. Evidence regarding the association between AS and peripheral artery disease (PAD) remains limited. We investigated whether patients with AS have an increased risk o...

Purpose This study investigates the impact of pop-up stores on online music merchandise sales within the context of concert tours. Design/methodology/approach Using customer-level transaction data from Best Band's (pseudonym) official online shop across more than 100 countries, w...

Machine learning integrated explainable artificial intelligence in predicting toxicities of enfortumab vedotin in urothelial carcinoma: an exploratory study

Background Enfortumab vedotin (EV) therapy for advanced urothelial carcinoma is limited by adverse events (AEs). Early identification of high-risk patients is needed. This proof-of-concept study evaluated whether machine learning (ML) with explainable AI (SHAP) could predict EV t...

Data poisoning in LLM multiagent societies: Social proof drives collective decision failure in financial deliberation

Abstract Large language model (LLM) multiagent systems are increasingly deployed for high‐stakes financial deliberation, but individually secure LLMs may become vulnerable when embedded in a peer‐to‐peer agent society. We study data poisoning in such societies using Moltbook, a d...

Oligoethylene Glycol Side‐Chain Engineering of Y6‐Derived Nonfullerene Acceptors for Thermally Induced Spontaneous Pseudo‐Planar Heterojunction Organic Photodetectors

ABSTRACT Dark current density ( J D ) fundamentally limits the noise characteristics and detectivity of organic photodetectors (OPDs), arising primarily from reverse‐bias carrier injection and trap‐mediated leakage pathways in donor‐acceptor (D‐A) bulk‐heterojunction (BHJ) active...

A report of 35 unrecorded bacterial species belonging to the classes Alphaproteobacteria and Betaproteobacteria in Korea

This dataset contains the digitized treatments in Plazi based on the original journal article Jung, Hye Su, Yoon, Jung-Hoon, Joh, Kiseong, Seong, Chi-Nam, Kim, Won-Yong, Im, Wan-Taek, Kim, Myung-Kyum, Cha, Chang-Jun, Kim, Seung-Bum, Jeon, Che-Ok (2021): A report of 35 unrecorded...

Long‐Lasting Electrohydrodynamically Printed Transparent Soft Microelectrode for Implantable Biointerfaces

ABSTRACT Reliable and scalable soft implantable neural interface fabrication remains a key challenge for chronic bioelectronic applications. Here, we present a transparent soft microelectrode fabricated with electrohydrodynamic (EHD) printing, utilizing the fluorinated polymer po...

Depression as a Risk of Lung Cancer in Women: a Nationwide Cohort Study

BACKGROUND: Lung cancer is a leading contributor to global cancer incidence and mortality. While depression has been linked to adverse health behaviors, particularly tobacco smoking, that may elevate cancer risk, the direct relationship between depression and lung cancer remains...

Spontaneous formation of picoliter water bridges

Picoliter water, ubiquitous at the microscale and predominantly confined between solids, underpins critical physical, chemical, and biological processes. Although vapor diffusion governs water evaporation in air, and capillarity inhibits evaporation at the nanoscale, neither mech...

Stabilizing High-Voltage Operation in O3-Type Na-Layered Cathodes by Suppressing Distortion-Driven Fe Migration

Abstract Fe-based O3-type Na-layered oxides such as Na[Ni1/3Fe1/3Mn1/3]O2 are attractive cathodes based on earth-abundant elements, yet their high-voltage operation is limited by voltage decay and capacity fading. Here, we identify a distortion−migration cascade initiated by Fe3+...

Sprayable MXene Hydrogels With Composition‐Driven Interfacial Stabilization and on‐Skin Gelation for Conformal Postsurgical Photothermal Therapy

ABSTRACT Oxidative degradation of Ti 3 C 2 T x MXene in aqueous and biological environments remains a persistent obstacle to its long‐term use in biomedical applications, yet the role of the surrounding polymer matrix in governing this process has received little systematic atten...
