All these provide evidence of Fenton reaction. It is noteworthy that •HO is a most reactive molecule, which can cause substantial damages to nearby molecular structures. As ROS oxidizes and hence damages macromolecules such as DNA, we also observed an up-regulated SOS response, an error-prone...

This study was designed to investigate Carmoisine degradationtion from solutions by oxidation processes using the Fenton reagent. The dye degradation process was monitored using a UV-Vis spectrophotometer. The effects of operating parameters that affect the efficiency of decolorization such as H2O2, Fe ...
In 1860 Frances Watkins married Fenton Harper. When he died in 1864, she returned to the lecture platform. After the Civil War, Harper made several lecture tours of the South with addresses on education, temperance, and other topics, and in 1872 she publishedSketches of Southern Life, a seri...
·generated in a non-enzymatic Fenton-type reaction, e.g., by the reduction of the O2with ascorbate in the presence of Cu ions. Thus, OH·produced in the CW under TM stress could act as a site-specific oxidant targeted to play a role in the CW loosening process supporting cell ...
