Multicomponent Molecular Editing of Polybutadiene: From Design Space to Battery Function

open access: yesAdvanced Science, EarlyView.
Multicomponent molecular editing transforms polybutadiene into an 18‐member polymer library with tunable thermal properties, nanoscale organization, and molecular dynamics. Mapping this multidimensional design space reveals distinct molecular input–property relationships and guides the selection of a candidate electrolyte additive for lithium–sulfur ...

Molecular MRI Reveals Macrophage‐Enriched Peritumoral Immune Remodeling After Incomplete Ablation in Liver Cancer

open access: yesAdvanced Science, EarlyView.
Incomplete microwave ablation (iMWA) induced a spatially organized, macrophage‐rich immunosuppressive tumor microenvironment (TME) in orthotopic VX2 liver tumors. Molecular MRI enhanced with europium‐doped very small superparamagnetic iron oxide nanoparticles (Eu‐VSOP) noninvasively visualized this remodeling, showing preferential nanoparticle ...

Stage‐Adaptive Bilayer Hydrogel Coordinates Photodynamic Antibacterial Therapy with Engineered Extracellular Vesicle–Mediated Immunomodulation in Infected Diabetic Wounds

open access: yesAdvanced Science, EarlyView.
Early photodynamic infection control and subsequent immunoregulatory repair are spatially separated within a stage‐adaptive bilayer hydrogel. Chlorin e6 is incorporated into the wound‐contacting layer to provide light‐triggered bactericidal therapy, whereas the upper layer regulates excessive reactive oxygen species before releasing microRNA‐146a ...

PHGDH‐Mediated Serine Metabolism in Nucleus Pulposus Cells Is a Potential Therapeutic Target for Intervertebral Disc Degeneration

open access: yesAdvanced Science, EarlyView.
When nucleus pulposus cells senesce, PHGDH decreases, reducing serine synthesis and glutathione, impairing antioxidant capacity. The intermediate α‐KG also drops, lowering JMJD3 demethylase activity, increasing H3K27me3 at the Rap1b promoter, and reducing Rap1b expression, whose down‐regulation in turn activates mTORC1 and suppresses autophagy ...

A Citrulline‐Functionalized Patch Coordinates Macrophage NRF2 Signaling and Arginine Metabolism for Tendon‐to‐Bone Repair

open access: yesAdvanced Science, EarlyView.
A locally implanted patch combines citrulline‐functionalized carbon dots, a thioketal‐containing membrane coating from tendon‐derived stem cells, and aligned core–shell fibers. In macrophages, the patch reduces inflammatory markers and enhances antioxidant signaling through nuclear factor erythroid 2‐related factor 2 (NRF2); in rats and rabbits, it ...
