Modulation of the TGF‐β/Smad Signaling Pathway by a Bioactive Oxidized Polygonati Rhizoma Polysaccharide Crosslinked Chitosan Hydrogel as Therapeutic Carrier for Parkinson's Disease Treatment

open access: yesAdvanced Science, EarlyView.
An injectable, self‐healing COPRP hydrogel integrates structurally defined oxidized Polygonati rhizoma polysaccharide with carboxymethyl chitosan through dynamic Schiff‐base crosslinking. The bioactive matrix scavenges reactive oxygen species, suppresses neuroinflammation, protects dopaminergic neurons, and supports sustained levodopa release.

Linker‐Locking Strategy for the Rigidification of Flexible Metal–Organic Framework: Structural Stabilization and Controlled ESIPT for H2O/D2O Sensing

open access: yesAdvanced Science, EarlyView.
A linker‐locking strategy rigidifies the flexible metal–organic framework (MOF) MIL‐53‐(OH)2 via the cooperative encapsulation of ligands and structural water. This network significantly enhances the framework's aqueous stability. Crucially, rigidification suppresses enol emission to yield a single keto tautomer state with an extended lifetime ...

Unlocking Li/Mg‐Based Photochemical Nitration Platforms for Anticancer Drug Discovery

open access: yesAdvanced Science, EarlyView.
Two low‐toxicity light main‐group metal photochemical systems based on lithium and magnesium are constructed for selective C(sp2)‐H (di)nitration of anilines. The obtained dinitrated products exhibit anti‐HCC (hepatocellular carcinoma) and anti‐KYSE30 cell activities, holding promise as novel antitumor candidates.

Anode‐Free Sodium Metal Batteries: From Materials Design to System‐Level Integration

open access: yesAdvanced Science, EarlyView.
Anode‐free sodium metal batteries hold no sodium reserve, so every inefficiency becomes permanent loss. Resolving the inventory into reversible, dead, and chemically bound fractions exposes what Coulombic efficiency hides. Practical 500‐cycle operation requires above 99.95%, a threshold few systems meet under lean electrolyte and high areal capacity ...

Compound Abrus cantoniensis Extract Alleviates AFB1‐Induced Liver Injury by Regulating PI3K‐AKT Pathway and Gut Microbiota/Butyrate Metabolism

open access: yesAdvanced Science, EarlyView.
ACCE has a good alleviating effect on AFB1‐induced liver injury, and this alleviating effect is related to the PI3K‐AKT pathway regulated by ACCE and the butyrate metabolism of gut microbiota. ABSTRACT Aflatoxin B1 (AFB1) is a potent hepatotoxin commonly ingested through contaminated food. Abrus cantoniensis Hance, a traditional Chinese medicinal herb,

High‐Performance Bio‐Based Epoxy Vitrimers and Composites: Synergizing Robustness and Reprocessability via Fractional Free Volume Regulation

open access: yesAdvanced Science, EarlyView.
In this work, two bio‐based epoxy monomers were designed to tune the dynamic network of a rigid–flexible hybrid epoxy through free‐volume control, achieving a synergy among high free volume, high cross‐linking density, and segmental mobility while balancing strength and toughness.

Lactylation‐Mediated HER2 Stabilization Promotes Trastuzumab Resistance in Gastric Cancer

open access: yesAdvanced Science, EarlyView.
Warburg effect‐derived lactate drives HER2 lactylation and trastuzumab resistance. Mechanistically, AARS1‐mediated lactylation stabilizes HER2 by inhibiting USP11‐dependent degradation and concurrently promotes HER2‐EGFR interaction. Importantly, inhibiting HER2 lactylation resensitizes gastric cancer cells to trastuzumab.

Computational and Data‐Driven Strategies for Lignocellulosic Biomass Valorization: From Multiscale Modeling to Digitalized Biorefinery Design

open access: yesAdvanced Science, EarlyView.
This Review critically connects structural recalcitrance, molecular modeling, solvent and catalyst design, pyrolysis, machine learning, reactor simulation, and FAIR digital infrastructure. Emphasis is placed on experimentally validated information transfer across scales, uncertainty and applicability domains, and the recycle, durability, techno ...

Scalable Fabrication of MOF Glass Membranes for Gas Separation via Stepwise Phase Transition

open access: yesAdvanced Science, EarlyView.
Metal‐organic framework (MOF) glass membranes, with their excellent processability and permanent pore structure, have great potential for gas separation applications. However, during large‐scale fabrication, defects and obvious cracks are prone to occur due to the limitations of powder processing.

Electronic‐State Programming of Ultrasmall CeO2 Switches H2O2 Activation From Radical to Bio‐Inspired Nonradical 1O2 Generation for Combating Antibiotic Resistance

open access: yesAdvanced Science, EarlyView.
A scalable synthesis of carbon‐supported ultrasmall CeO2 nanoparticles with precisely tunable Ce electron density is reported. Electron‐lean Ce sites activate H2O2 exclusively via a nonradical pathway, enabling efficient HOBr and 1O2 production analogous to bromoperoxidase for contaminant and antibiotic resistance removal.
