Manipulating Charge Dynamics in Carbon Nitride by Carbon Dot Doping for Efficient Photocatalysis

Advanced Science, EarlyView.
A series of carbon dot (CD) doped graphitic carbon nitride (g‐C3N4) materials have been rationally synthesized, which exhibited different photophysical properties, excitonic behaviors, and photocatalytic degradation activities. It provides valuable insights to deepen the understanding of exciton dynamics based on g‐C3N4 materials, and rational design ...

Decursin‐Loaded Nanovesicles Target Macrophages Driven by the Pathological Process of Atherosclerosis

Advanced Science, EarlyView.
This study presents decursin, a traditional Chinese medicine monomer, that inhibits lipid accumulation and inflammation in atherosclerosis through PKCδ interaction. A novel targeted delivery system (ALD@EM) is developed to overcome decursin's short half‐life, combining antibody‐mediated targeting, LDL‐facilitated chemotaxis, and enhanced macrophage ...

Manipulation of Oxygen Tension in Damaged Regions via Hypoxia‐Induced IPN Hydrogel Microspheres for Intervertebral Disc Regeneration

Advanced Science, EarlyView.
A novel interpenetrating network hydrogel microsphere (NSC‐Exos@HIMS) is developed to manipulate oxygen tension in damaged regions and recruit endogenous stem cells. In vitro and in vivo results show that NSC‐Exos@HIMS maintains the hypoxia microenvironment for up to 5 days, which triggers nucleus pulposus cell‐like differentiation and enhanced ECM ...

The macrophage scavenger receptor at 30 years of age: current knowledge and future challenges

Journal of Lipid Research, 2009
It is now thirty years since the original observation that macrophages take up and degrade modified forms of low density lipoprotein (LDL). Molecular cloning has identified multiple scavenger receptors that can endocytose modified LDL and binding studies

Synergistic Machine Learning Guided Discovery of ABa3(BSe3)2X (A = Rb, Cs; X = Cl, Br, I): A Promising Family as Property‐Balanced IR Functional Materials

Advanced Science, EarlyView.
A synergistic framework for interpretable ML‐assisted target discovery of selenoborates is developed. ABa3(BSe3)2X (A = Rb, Cs; X = Cl, Br, I) are successfully predicted and synthesized, exhibiting significant potential to be promising IR functional materials. This work promotes the cooperation of ML technology and materials science.

Scavenger receptor BI (SR-BI) mediates free cholesterol flux independently of HDL tethering to the cell surface

Journal of Lipid Research, 1999
In addition to its effect on high density lipoprotein (HDL) cholesteryl ester (CE) uptake, scavenger receptor BI (SR-BI) was recently reported to stimulate free cholesterol (FC) flux from Chinese hamster ovary (CHO) cells stably expressing mouse SR-BI, a

A Bio‐Responsive Hydrogel with Spatially Heterogeneous Structure for Treating Infectious Tissue Injuries

Advanced Science, EarlyView.
The hydrogel incorporates Ag⁺‐loaded Preyssler‐type polyoxometalates (POMs) that release Ag⁺ ions in response to endogenous Na⁺ ions, ensuring controlled antibacterial activity. The spatially heterogeneous structure, created through dual‐channel fiber stacking and in situ cross‐linking, enhances structural integrity and promotes tissue regeneration ...
