This demonstrated that the hydroxyl groups can greatly increase the light-responsive catalytic activity of CDs, while the slight amount of carboxyl groups acts as an inhibitor of catalytic activity
There are some data that acute COVID-19 infection is accompanied by signs of oxidative stress, including increased expression of ROS-response genes and glycolysis in peripheral blood mononuclear cells [72], increased MDA (TBARS assay), F-isoprostane, 8-hydroxy-2-deoxyguanosine, AOPP and nitrotyrosine levels, and lowered glutathione (GSH), -SH groups, selenium, zinc, TAC and vitamin D [49, 73,74,75,76,77,78,79]
