Rhein-induced free fatty acid generation cooperates with silver ions for biofilm-infected diabetic wound healing

Diabetic foot infection (DFI) significantly increases the risks of hospitalization and amputation, with biofilm infections caused by methicillin-resistant Staphylococcus aureus (MRSA) and carbapenem-resistant Escherichia coli (CREC) being key drivers of treatment failure. Here, w...

Oral small-molecule GLP-1 receptor agonist safiglipron in early type 2 diabetes: a randomized, double-blind, placebo-controlled trial

Abstract Safiglipron is an oral small-molecule glucagon-like peptide-1 (GLP-1) receptor agonist administered without fasting or dietary restrictions. We evaluated its efficacy and safety in OUTSTAND-1, a phase 3, multicenter, randomized, double-blind, placebo-controlled trial at...

Biotin‐Engineered Phenothiazine Photosensitizer Boosts Type I Photodynamic Therapy via Singlet‐Excited‐State Electron Transfer

Comprehensive Summary Type II‐dominant photosensitizers often suffer from reduced photodynamic efficacy under tumor hypoxia. We report a biotin‐modified phenothiazine photosensitizer termed DHU‐Blue‐7, which converts type II methylene blue (MB)‐like photosensitization into a type...

Multi-omics insights into growth impairment mechanisms in children with persistent diarrhea

ABSTRACT This study aimed to elucidate the key mechanisms underlying short stature with pediatric persistent diarrhea in children (PDC) and to propose an integrated model linking the butyrate-producing gut microbial niche, short-chain fatty acids (SCFAs), Th17/Treg balance, the g...

Computed tomography portal venous reconstruction assisted endoscopic ultrasound-guided selective inflow vessel devascularization for the treatment of type 1 gastroesophageal varices

EUS-guided combination therapy (coil and hemostatic glue) for bleeding and non-bleeding gastric varices has recently attracted considerable attention after promising results were published in multiple small studies. We performed a meta-analysis to investigate the safety and effic...

Oral nonpeptide GLP-1 receptor agonist VCT220 for obesity treatment: a randomized, double-blind, phase II trial

VCT220 is a novel nonpeptide, orally available glucagon-like peptide-1 receptor agonist (GLP-1RA) designed to reduce the complex administration of injectable GLP-1RAs and the limited bioavailability of on-marketing oral agents for obesity care. We conducted a multicenter, randomi...

Optimization of the Sequence of Computed Tomography Angiography and Perfusion in One-Stop-Shop CT Imaging for Acute Ischemic Stroke

Background:In the "one-stop-shop" stroke computed tomography (CT) scanning protocol, CT perfusion (CTP) can be performed either before or after CT angiography (CTA).This study analyzed the effect of different scanning strategies in one-stop-shop stroke CT on CTA image quality and...

Development and external validation of a machine learning model for early identification of hypotension associated with renal replacement therapy in ICU patients

Renal replacement therapy (RRT) is essential for critically ill patients in the intensive care unit (ICU), yet hypotension remains its most common complication, increasing the risk of organ hypoperfusion and poor outcomes. No reliable tool currently exists to predict hypotension...

Hierarchical ROS-scavenging hydrogel system for coordinating the modulation of RGC necroptosis and oxidative stress in an acute glaucoma model

Glaucoma, a leading cause of irreversible blindness, is characterized by the progressive loss of retinal ganglion cells (RGCs). Beyond intraocular pressure (IOP)-dependent injury, IOP-independent pathways, specifically the self-amplifying axis between oxidative stress and the nec...

A dual role of PIEZO2 in neuropathic pain: driving peripheral sensitization and enabling mechanical loading-induced analgesia

Mechanotherapy, a form of mechanical loading (ML), effectively relieves tactile allodynia-associated neuropathic pain by targeting sensitization points stimulated by PIEZO2, a mechanosensitive ion channel. However, the molecular mechanisms underlying peripheral sensitization and...

Prognostic model for gastric cancer integrating immune biomarkers and machine learning approaches

Prognostication for advanced gastric cancer remains sub-optimal because conventional staging systems overlook systemic inflammation and tumour-immune contexture. We investigated whether incorporating routine immune biomarkers into machine-learning survival models improves risk st...
