All‐Flex Plasma Patch for In Vivo Delivery of Reactive Species

Advanced Science, EarlyView.
A fully flexible plasma patch enables stable, conformal treatment on complex biological surfaces and enhances transdermal delivery of reactive species. This platform achieves significant tumor suppression in vivo and reveals coordinated regulation of calcium signaling, metabolism, and programmed cell death, providing a promising strategy for safe and ...

Ultra‐Radiostable Covalent Conformationally Interlocked Networks Enabling a Universal Radiometal‐Labeling Platform for Cancer Radioembolization

Advanced Science, EarlyView.
Conjugated poly(imide dioxime)‐based microspheres establish a radiometal coordination‐driven conformational interlocked network with ultra‐high radiostability. This platform enables low‐temperature, multi‐radionuclide labeling for SPECT/PET/MRI imaging and radionuclide therapy. Mechanistic insights from EXAFS and DFT reveal enhanced stability, while in

The miR‐126‐5p and miR‐212‐3p in the extracellular vesicles activate monocytes in the early stage of radiation‐induced vascular inflammation implicated in atherosclerosis

Journal of Extracellular Vesicles, 2023
People exposed to radiation in cancer therapy and nuclear accidents are at increased risk of cardiovascular outcomes in long‐term survivors. Extracellular vesicles (EVs) are involved in radiation‐induced endothelial dysfunction, but their role in the ...

Applicability of the LSC technique for determining 210Pb in liquid samples for purposes of dose assessment via in vitro bioassay

Brazilian Journal of Radiation Sciences, 2022
A new approach for the determination of 210Pb by liquid scintillation counting was developed by the LBIOVT. In order to assess the applicability of the technique for internal monitoring of occupationally exposed workers and members of the public, some ...

Kaempferol Attenuates Spaceflight‐Associated Knee Cartilage Degradation by Targeting NOX4‐Mediated Mitochondrial Dysfunction

Advanced Science, EarlyView.
We have shown that both simulated and actual spaceflight contribute to cartilage degradation in the knees of mice. Using RNA sequencing and bioenergetic profiling, we identified NADPH oxidase 4 (NOX4) as a key factor driving these changes. Additionally, we found that kaempferol, a naturally occurring flavonoid that binds directly to NOX4, reduces ...
