Programmable Microgel Degradation in Dynamic Granular Hydrogels Guides Extracellular Matrix Assembly During Tissue Repair

open access: yesAdvanced Materials, EarlyView.
This study reports on the chemical modification of hyaluronic acid to create hydrogels with hydrolytic degradability ranging from 2–28 days. Granular hydrogels that undergo timed degradation to increase porosity enhance cell invasion and provisional ECM remodeling in a muscle injury model, leading to reduced fibrosis and improved regeneration ...

A Retinal Matrix Stiffening Model Reveals FAK‐Dependent Mechanotransduction in Pericytes Underlies Vascular Destabilization

open access: yesAdvanced Materials, EarlyView.
In this study, we show that retinal matrix stiffness is increased in diabetic mice. Using engineered human vascular models with controlled matrix stiffness, we demonstrate that stiffening activates focal adhesion kinase (FAK) signaling in pericytes, suppresses Notch signaling, and disrupts vascular morphology.

Anchored Fluoro‐Shielded Solvation for Lithium Metal Batteries

open access: yesAdvanced Materials, EarlyView.
Anchored fluoro‐shielded solvation reconstructs PVDF‐based polymer electrolytes by coupling polyanionic Li+‐solvate sites with fluorinated shielding segments. This design organizes anion‐rich solvation networks, strengthens selective Li+ transport, and generates LiF‐rich solid electrolyte interphase, enabling high conductivity, wide oxidative tolerance,

Post Cholecystectomy Choledochoduodenal Fistula: A Case Report

open access: yesJournal of Nepal Medical Association
Choledochoduodenal fistula is an abnormal connection between the common bile duct and the duodenum. The commonest cause is cholecystolithiasis, however, other causes are iatrogenic factors, bile duct stones (choledocholithiasis), and chronic duodenal ...

A Noninvasive Approach to Study Localized Forces in 3D Epithelia

open access: yesAdvanced Materials, EarlyView.
Epithelial morphogenesis depends on dynamic mechanical coupling between adhesion complexes and the cytoskeleton, yet its regulation in polarized 3D tissues remains elusive. We developed a noninvasive strategy using cell‐like elastic microbeads to quantify local forces in intact epithelia.

Direct cholangioscopy for recurrent pancreatitis after choledochal cyst surgery: Its role in diagnosis and surveillance

open access: yesInternational Journal of Gastrointestinal Intervention
We report the case of a 20-year-old woman with a complex type “D” pancreaticobiliary maljunction and recurrent pancreatitis who underwent surgical resection with Roux-en-Y reconstruction. Fourteen years later, magnetic resonance cholangiopancreatography (

An Engineered Thio‐Amino Polymer Achieves Potent, Safe, and Broad Cell Type Delivery in the Lung Mapped by Spatial Transcriptomics

open access: yesAdvanced Materials, EarlyView.
Synthesis and screening of a polymer library produced a versatile and inhalable mRNA vehicle for the lungs (P81). Compared to a published LNP, P81 provides increased delivery efficacy, achieving widespread expression in broad cell types, with no toxicity.

Reduced Graphene Oxide Enhances the Vascular Organization and Contractile Performance of Fibrin‐Gelatin‐Based Engineered Cardiac Tissue

open access: yesAdvanced Materials Interfaces, EarlyView.
Fibrin–gelatin hydrogels functionalized with reduced graphene oxide create a mechanically stable and bioactive 3D environment for engineered cardiac tissue. The composite matrix promotes endothelial lumen formation, enhances sarcomeric protein expression, and increases contractile performance of embedded cardiomyocytes.
