Low-cost geometry-tunable PDMS intraocular lenses fabricated using LCD 3D-printed molds for canine ophthalmic applications

This study demonstrates the feasibility of fabricating geometry-tunable polydimethylsiloxane (PDMS) intraocular lens (IOL) prototypes using consumer-grade liquid crystal display (LCD) 3D-printed molds and PDMS casting. A reusable mold fabrication strategy incorporating a PMMA bar...

Screening strategies for the early detection of non-cardia gastric cancer in low- to moderate-prevalence regions: Asia-Pacific gastroesophageal cancer congress consensus 2026

Abstract Background Gastric cancer (GC) remains a major global health burden, and early detection is essential for improving patient outcomes. Although GC screening has been widely implemented in East Asian countries with a high disease burden, the optimal screening strategy for...

Nutrients and Their Role in Autophagy Regulation

Abstract Autophagy is a fundamental catabolic pathway that maintains cellular homeostasis through the degradation and recycling of intracellular components in response to nutrient limitation and metabolic stress. Increasing evidence indicates that autophagy is tightly regulated b...

Enhancing the Properties of Devulcanized Natural Rubber Through Sulfur Revulcanization Followed by Electron Beam Postcuring

ABSTRACT Devulcanized natural rubber (DNR) is a sustainable material with potential for circular resource utilization. This study investigated electron‐beam irradiation as a postcuring treatment for sulfur‐revulcanized DNR over a dose range of 0–500 kGy. Irradiation promoted addi...

GaPt alloy in HZSM ‐5 for highly stable ethane dehydroaromatization

Abstract The dehydroaromatization of ethane to aromatics is a highly attractive yet challenging route for valorizing the second‐most abundant component of natural gas. Here, we report bimetallic xGa0.8Pt/HZSM‐5 catalysts that exhibit markedly enhanced stability and coke resistanc...

Incident Catatonia in Elderly Patients With Chronic Psychosis: Clinical Trajectories and Management Outcomes — A Case Series

Background Incident catatonia in older adults with chronic psychosis may signal underlying organic pathology rather than primary psychiatric exacerbation. We describe three patients with different vulnerability profiles. Methods This retrospective series reviews the clinical cour...

Bromine Retention Versus Electrochemical Accessibility in a Ferri‐/Ferrocyanide–Bromine Flow Battery

Bromine retention in aqueous redox flow batteries can be improved by complexation, but the resulting gain in stability is often accompanied by losses in electrochemical accessibility and transport. Here, we investigate a ferri‐/ferrocyanide–bromine flow battery based on soluble f...

Effects of Physical-Cognitive Exercise on Attention and Serum Brain-Derived Neurotrophic Factor in Male University Esports Athletes

This study investigated the effects of combined physical–cognitive exercise on attentional performance and serum brain-derived neurotrophic factor (serum BDNF) levels in male varsity esports athletes. Thirty-two participants were allocated into four groups: physical–cognitive exe...

Advancing graphene-enabled piezoelectric, triboelectric, and hybrid nanogenerators: A review on mechanistic and performance optimization

Graphene significantly enhances the performance of piezoelectric (PENG), triboelectric (TENG), and hybrid piezoelectric-triboelectric (H-P/TENG) nanogenerators by regulating polarization, dielectric behavior, charge transport, and interfacial coupling. This review presents a crit...

Defect-rich three-dimensionally ordered macroporous magnesium cobalt oxide spinel coupled with graphite felt for vanadium redox flow batteries

Developing electrodes that simultaneously enable rapid redox kinetics and efficient mass transport is critical for advancing high-performance vanadium redox flow batteries (VRFBs). Herein, a defect-rich three-dimensionally ordered macroporous MgCo 2 O 4 catalyst is integrated ont...

A Multinational Study of Orientation-Aware Deep Learning for Automated Detection of Retained Roots and Periodontal Bone Loss

Introduction and aims Accurate radiographic assessment of retained roots (RR) and periodontally compromised teeth (PCT) are critical for dental diagnosis. This study aimed to develop and evaluate deep learning models for the automated detection and classification of these patholo...

Cold Snare Polypectomy Versus Cold Snare Polypectomy With Submucosal Injection for 3–9 mm Colorectal Polyps: A Randomized Controlled Trial

ABSTRACT Background and Aim Incomplete resection after cold snare polypectomy (CSP) remains a concern. CSP may sometimes require a forcible pull (“forced CSP”), which increases the incomplete resection rate (IRR). Submucosal injection before CSP (SI‐CSP) may facilitate resection...
