A multifunctional hydroxyapatite (HAp) coating integrated with silver‐gallium liquid metal nanoparticles (HAp‐Ag‐GaNPs) exhibits dual antibacterial and osteogenic properties. It effectively inhibits Gram‐positive and Gram‐negative bacteria, including resistant strains, while enhancing bone regeneration.

Cell Membrane Vesicle Camouflaged Artificial Cells
Artificial cells camouflaged with a cell membrane vesicle coating are able to assemble into synthetic aggregates that exhibit rudimentary communication capabilities. Additionally, when these artificial cells are equipped with antioxidant capabilities, they are able to protect the intracellular homeostasis in HepG2 cells present in semi‐synthetic ...

H2O2‐Generating Advanced Nanomaterials for Cancer Treatment
H2O2‐generating nanoplatforms can exploit tumor redox imbalance for O2 and toxic reactive oxygen species generation, leading to hypoxia reversal, and apoptosis of cancer cells, respectively. This review highlights the mechanisms of these nanoplatforms, including exogenous H₂O₂ delivery, endogenous amplification, and metal peroxides, which leads to ...

The PVA‐GA hydrogel is formed through hydrogen bonding between PVA hydroxyl groups and GA galloyl units, enabling sustainable GA release and its extended biological activity. The hydrogel scavenges ROS to reduce oxidative stress, preventing mitochondrial damage from excessive ROS, mitigating hADSC senescence, and preserving VEGF secretion, offering a ...

Targeting Cholangiocarcinoma Cells By Cold Piezoelectric Plasmas: In Vitro Efficacy And Cellular Mechanisms [PDF]
Cold piezoelectric plasma (CPP) is a novel approach in cancer therapy, enabling the development of portable treatment devices capable of triggering cancer cell death. While its effectiveness remains underexplored, this research focuses on its application against cholangiocarcinoma (CCA), an aggressive cancer of the biliary tract.

Deinococcus radiodurans‐derived extracellular vesicles (R1‐EVs) provide radioprotection against total‐body irradiation‐induced acute radiation syndrome in mice. R1‐EVs mitigate oxidative damage by scavenging free radicals, promoting intestinal repair, enhancing hematopoietic function, and modulating immune responses. This study highlights the potential

This study reports a novel strategy for preparing a biocompatible adhesive hydrogel crosslinked with a muscle tissue‐derived extracellular matrix (MEM) for in situ muscle regeneration. As a natural crosslinker, MEM not only mediates combinatorial polymer networks but also stimulates satellite cells to induce a cell‐free therapeutic solution.

Cybernetic Principles of Aging and Rejuvenation: the buffering-challenging strategy for life extension [PDF]
Aging is analyzed as the spontaneous loss of adaptivity and increase in fragility that characterizes dynamic systems. Cybernetics defines the general regulatory mechanisms that a system can use to prevent or repair the damage produced by disturbances. According to the law of requisite variety, disturbances can be held in check by maximizing buffering ...
