Dual‐Biomimetic Bone Adhesive with Osteoimmunomodulatory Capabilities for Anatomical Reconstruction of Comminuted Fractures

open access: yesAdvanced Science, EarlyView.
A structurally and functionally dual bionic bone adhesive is engineered through an organic–inorganic cohesion strategy, which significantly reinforces the adhesive's bone tissue adhesion as well as osteogenic activity. In a pioneering rabbit radius comminuted fracture model, the bone adhesive exhibits exceptional capability in immobilizing bone ...

Hepatic ENTPD5 Is Critical for Maintaining Metabolic Homeostasis and Promoting Brown Adipose Tissue Thermogenesis

open access: yesAdvanced Science, EarlyView.
ENTPD5‐mediated conversion of extracellular adenosine triphosphate to ADP of hepatocytes is critical for maintaining hepatic glucose/lipid metabolism and promoting brown adipose tissue thermogenesis via the inhibition of adrenomedullin expression and secretion.

Shifting Acetylene Hydrochlorination From the Gas to the Liquid Phase: Vinyl Chloride Production in Bichloride‐Based Ionic Liquids

open access: yesAdvanced Science, EarlyView.
Combining the bichloride‐based ionic liquid [NEt3Me][Cl(HCl)n] with PdCl2 results in the formation of the highly active, mercury‐free catalyst [NEt3Me]2[PdCl4] for acetylene hydrochlorination to vinyl chloride. Replacing HCl with the bichloride improves the process safety and achieves a competitive turnover frequency of 110 molVCM h−1 molPdCl2−1.

Human iPSCs Derived MSCs‐Secreted Exosomes Modulate Senescent Nucleus Pulposus Cells Induced Macrophage Polarization via Metabolic Reprogramming to Mitigate Intervertebral Disc Degeneration

open access: yesAdvanced Science, EarlyView.
Senescent nucleus pulposus cells drive inflammatory M1 macrophage polarization, exacerbating intervertebral disc degeneration (IDD). Conversely, M1 macrophages accelerate NP cell senescence, creating a vicious cycle. iPSCs‐derived mesenchymal stem cell (iMSCs) exosomes break this loop by delivering miR‐100‐5p to suppress mTORC1/glycolysis in ...

Lysosome‐Featured Cell Aggregate‐Released Extracellular Vesicles Regulate Iron Homeostasis and Alleviate Post‐Irradiation Endothelial Ferroptosis for Mandibular Regeneration

open access: yesAdvanced Science, EarlyView.
Lysosomal redistribution occurs via extracellular vesicles in multi‐stem cell aggregates and controls iron homeostasis for safeguarding cell aggregation. These cell aggregate‐released extracellular vesicles (CA‐EVs) rescue lysosomal impairments and exert anti‐ferroptosis effects in recipient irradiated endothelial cells.

Unveiling the Fundamental Principles of Reconfigurable Resistance States in Silver/Poly(Ethylene Glycol) Nanofluids

open access: yesAdvanced Science, EarlyView.
The electrophoretic reorganization of Ag nanoparticles within a poly(ethylene glycol) leads to the formation of conductive bridges with reconfigurable resistance states. Diverse conduction characteristics of the bridge range between ohmic conduction, nonlinear tunneling, or space charge‐limited conduction, and high resistance states.
