Hydroxyl Radical Induced Ultra-Weak Photon Emission from Tyrosine Solutions
Communications, 2015 This paper deals with ultra-weak photon emission (UPE) from aqueous tyrosine solutions induced by hydroxyl radical. The physical nature of this specific phenomenon is presented and the proposed mechanism of its origin during oxidation of tyrosine is ...

Preindustrial to present-day changes in tropospheric hydroxyl radical and methane lifetime from the Atmospheric Chemistry and Climate Model Intercomparison Project (ACCMIP) [PDF]
, 2013 We have analysed time-slice simulations from 17 global models, participating in the Atmospheric Chemistry and Climate Model Intercomparison Project (ACCMIP), to explore changes in present-day (2000) hydroxyl radical (OH) concentration and methane (CH4 ...

Electrochemical Interaction Between Free Radicals and Lappaconitines
International Journal of Electrochemical Science, 2018 We used electrochemical analysis methods to study how the aconitum alkaloids lappaconitine and its salts (HBr-lappaconitine, HCl-lappaconitine) scavenge free radicals (superoxide anion radical, 2,2-diphenyl-l-picrylhydrazyl, hydroxyl radical and lipid ...

Histamine as a marker for hydroxyl radicals [PDF]
Mediators of Inflammation, 1995 During inflammation an influx of neutrophils and release of mediators from mast cells (such as histamine) take place. The stimulated neutrophils can produce reactive oxygen species (ROS). One of these ROS is the highly reactive hydroxyl radical (OH.). It would be interesting to be able to quantify the extent of ROS formation.

Study on Hydroxyl Radical Scavenging Ability of Fermented Kelp Waste
Chemical Engineering Transactions, 2016 In order to develop a new pathway to scavenge hydroxyl radical and to utilize kelp waste, edible-medicinal fungi was fermented in medium mainly composed of kelp waste, and the products from fermentation were investigated with hydroxyl radical scavenging ...

Design of a two-dimensional interplanar heterojunction for catalytic cancer therapy
Nature Communications, 2022 Chemodynamic therapy relies on Fenton or Fenton-like reactions to produce hydroxyl radical in the tumor region. Here the authors design a two-dimensional interplanar heterojunction with in situ hydroxyl radical generation under ultrasound irradiation ...
