Restoring Endothelial Mitochondrial Homeostasis With a Bioactive Nanoshield Promotes Vascular Regeneration on Cardiovascular Implants

Advanced Science, EarlyView.
A bioactive poly(citrate‐polyglycol‐procyanidin) (PCGP) nanoshield is developed for cardiovascular implants to restore endothelial mitochondrial homeostasis following vascular injury. By preserving mitochondrial integrity, re‐establishing metabolic balance, and activating PI3K/Akt/eNOS‐NO signaling, the PCGP interface promotes functional endothelial ...

Water‐Soluble Luminescent Trityl Radical for Fluorescence/Magnetic Resonance Dual‐Modal Imaging Probe

Advanced Science, EarlyView.
Stable water‐soluble luminescent tris(2,4,6‐trichlorophenyl)methyl (TTM) radicals, TTM‐trisTP3B and TTM‐trisTP9B, were designed and successfully synthesized. They exhibited deep‐red emissions and high photostability in water. TTM‐trisTP3B exhibited dual functionality as a fluorescence imaging (FI) probe and a magnetic resonance imaging (MRI) contrast ...

Spatiotemporally Controlled Sequential Chemo‐Immunotherapy Activates Pyroptosis for Robust Anti‐Tumor Immunotherapy

Advanced Science, EarlyView.
A glutathione and ultrasound dual‐responsive cerasome achieves sequential co‐delivery of gemcitabine and BMS1166 in tumors. Chemotherapy priming followed by on‐demand PD‐L1 blockade synergistically amplifies anti‐tumor immunity, inhibiting primary tumor growth, distant metastasis and inducing durable immune memory.

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

Advanced 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.
