Lactobacillus‐Loaded Bioadhesive Hydrogel with Prolonged Retention and Microenvironmental Remodeling for Endometrial Repair and Fertility Restoration

open access: yesAdvanced Science, EarlyView.
A bioactive adhesive hydrogel capable of long‐term uterine retention (>14 days) and local microenvironment modulation is developed by straightforward integration of α‐lipoic acid, L‐arginine, tannic acid, and Lactobacillus johnsonii, which can markedly enhance endometrial repair and restore fertility in a rat model of endometrial injury.

Engineered Cyanobacteria‐Hydrogel Microecological System for Oxygen Reprogramming Synergizes Immunomodulation With Anabolism in Osteoarthritis Therapy

open access: yesAdvanced Science, EarlyView.
An injectable cyanobacteria‐laden hydrogel enables light‐dependent oxygen metabolism engineering for osteoarthritis therapy. Photosynthetic oxygen release under red light irradiation suppresses synovial inflammation via HIF‐1α inhibition and M2 macrophage polarization, while respiratory oxygen consumption in darkness stabilizes chondrocyte HIF‐1α to ...

D4F‐Functionalized Ceria Nanozyme‐CasRx Platform Suppresses STING and Reprograms the Renal Immune Niche in Acute Kidney Injury

open access: yesAdvanced Science, EarlyView.
D4F‐functionalized ceria nanozyme–CasRx nanoparticles preferentially target renal macrophages through SR‐B1‐mediated uptake in ischemia–reperfusion injury. Ceria scavenges excessive ROS, while CasRx silences STING signaling, shifting macrophages toward a less inflammatory, pro‐resolving state and increasing the proportion of regulatory T cells.

Mitochondria‐Targeted Multimodal Nanotherapeutics Suppress Oxidized mtDNA‐Driven Inflammation at the Source

open access: yesAdvanced Science, EarlyView.
Ox‐mtDNA fragments escaping from mitochondria drive robust inflammatory responses. A targeted nanoplatform simultaneously inhibits mitochondrial FEN1‐mediated mtDNA cleavage and scavenges ROS, preventing the generation of immunogenic Ox‐mtDNA fragments. The released SeNPs further promote autophagic clearance of cytosolic mtDNA. Consequently, cGAS‐STING,

Electrochemical monitoring of DPPH radical-scavenging reactions enables structural classification of antioxidant reaction mechanisms

open access: yesAdvances in Redox Research
DPPH radical (DPPH•) scavenging reactions by antioxidants were monitored using continuous cyclic voltammetry. Electrochemical responses of both DPPH• and the antioxidants were simultaneously recorded, and the reversibility of electron transfer was ...

Supramolecular Zinc–Polyphenol Coordination Assemblies Mitigate Colonic Inflammation by Regulating Mucosal Barrier and Microbiome

open access: yesAdvanced Science, EarlyView.
A carrier‐free zinc‐coordinated polyphenol nanoplatform (ZnCA NPs) is designed as an “all‐in‐one” therapeutic strategy for intestinal inflammation. The ZnCA NPs exhibit enhanced colonic accumulation and broad‐spectrum reactive oxygen and nitrogen species scavenging.
