Cell Membrane Vesicle Camouflaged Artificial Cells

Advanced Functional Materials, EarlyView.
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 ...

Bacteria‐Derived Extracellular Vesicle as A “Trojan Horse” for Selective M1 Macrophage‐Targeting in A Multi‐Cellular Entanglement Environment

Advanced Functional Materials, EarlyView.
The temporary transition of macrophages from a pro‐inflammatory phenotype of macrophages (M1) to an anti‐inflammatory phenotype of macrophages (M2) is crucial for tissue repair and regeneration processes. Bacterial outer membrane vesicles (OMVs) are utilized as a “trojan horse” for specific M1 macrophage‐targeting and anti‐inflammatory drug delivery ...

A Thermodynamic Model for Receptor Clustering [PDF]

, 1999
Intracellular signaling often arises from ligand-induced oligomerization of cell surface receptors. This oligomerization or clustering process is fundamentally a cooperative behavior between near-neighbor receptor molecules; the properties of this cooperative process clearly affects the signal transduction.

Biomimetic Co‐delivery of Lenvatinib and FePt Nanoparticles for Enhanced Ferroptosis/Apoptosis Treatment of Hepatocellular Carcinoma

Advanced Healthcare Materials, EarlyView.
This study introduces a novel HCC treatment using poly lactic‐co‐glycolic acid (PLGA) nanoparticles encased in HCC cell membranes to co‐deliver Lenvatinib and FePt nanoparticles. This approach improves treatment efficacy by enhancing ferroptosis and apoptosis.

Increasing the Efficiency of Energy Scavengers [PDF]

arXiv, 2007
In this paper, a methodology for designing efficient energy scavengers is proposed. The scavenger consists of a cantilever beam on which piezoelectric films and a mass are mounted. The mass at the tip of the beam is known as the proof mass and the device is called either an energy scavenger or a beam-mass system.

Radiation‐Resistant Bacteria Deinococcus radiodurans‐Derived Extracellular Vesicles as Potential Radioprotectors

Advanced Healthcare Materials, EarlyView.
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

Effect of human scavenger receptor class A overexpression in bone marrow-derived cells on lipoprotein metabolism and atherosclerosis in low density lipoprotein receptor knockout mice

Journal of Lipid Research, 2000
Scavenger receptors, which include various classes, play an important role in atherogenesis by mediating the unrestricted uptake of modified lipoproteins, resulting in the massive accumulation of cholesteryl esters.

Design of Energy Scavengers Mounted on Rotating Shafts [PDF]

arXiv, 2008
In this paper, a novel energy scavenger is proposed. The scavenger consists of a cantilever beam on which piezoelectric films and a mass are mounted. The mass at the tip of the beam is known as the proof mass and the device is called either an energy scavenger or a beam-mass system. The beam-mass system is mounted on a rotating shaft, where the axis of
