From Exciton Dynamics to Cell Fate: A Carbon Dot Based NIR Photocatalytic Platform for Pyroptosis via Self‐Trapped Excitons

Advanced Functional Materials, EarlyView.
A facile and effective method to boost NIR light induced photocatalysis based on nontoxic NIR emissive carbon dots (nir‐CDs) via Self‐trapped excitons, showing that both O2− • and •OH can be generated from nir‐CDs under NIR laser irradiation. Abstract Near‐infrared (NIR) light‐triggered photocatalytic therapy remains a critical challenge in efficient ...

Extracellular superoxide dismutase VdSOD5 is required for virulence in Verticillium dahliae

Journal of Integrative Agriculture, 2021
Plants produce reactive oxygen species (ROS) to defend pathogens. To counteract this attack, certain pathogens express superoxide dismutases (SODs) to scavenge host-derived ROS.

The antioxidant effects of vitamin C on liver enzymes: aspartate aminotransferase, alanine aminotranferease, alkaline phosphatase and gamma-glutamyltransferase activities in rats under Paraquat insult

Journal of Xenobiotics, 2013
Paraquat (PQ) is a bipyridylium herbicide; applied around trees in orchards and between crop rows to control broad-leaved and grassy weeds. Its oxidation results in the formation of superoxides which causes damage to cellular components.

Enhanced Sonodynamic Bacterial Elimination and Wound Healing Therapy Based on Lanthanide Ion Doped Bi2WO6 Nanosheets and Hydrogel Platform

Advanced Functional Materials, EarlyView.
Lanthanide ytterbium ions are introduced into Bi2WO6 nanosheets to boost ROS generation under US stimulation. These ytterbium‐doped Bi2WO6 nanosheets serve as efficient sonosensitizers, enabling broad‐spectrum bacterial eradication. To improve biocompatibility for in vivo sonodynamic therapy, the sonosensitizers are integrated into hydrogel matrix ...

Synthetic Bilirubin‐Based Nanomedicine Protects Against Renal Ischemia/Reperfusion Injury Through Antioxidant and Immune‐Modulating Activity

Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
BX‐001N, a polyethylene glycol‐conjugated bilirubin 3α nanoparticle, is the first GMP‐grade, synthetic bilirubin‐based nanomedicine. It effectively attenuates acute renal injury, facilitates subacute renal recovery, and suppresses chronic fibrosis after renal ischemia/reperfusion injury via anti‐oxidant and immune‐modulating activity.
