Abstract:
... Exogenous toxicants (e.g. arsenic, cigarette smoke), trigger oxidative stress, and initiate the pathogenesis of many human diseases. Induction of nuclear factor E2-related factor 2 (Nrf2) counteract exogenous toxicant-induced oxidative insults. Using a high-throughput screen, we firstly identified a citrus polymethoxyflavone, (2S)-5,6,7,3',4'-pentamethoxyflavanone (PMF), to be an Nrf2 activator, a ...

In order to effectively eliminate pollution of arsenic and explore the adsorption mechanism, a novel-innovative hydrated zirconium oxide (ZrO(OH)₂) and manganese dioxide (MnO₂) coated modified activated charcoal (Zr/Mn/C) prepared via a co-precipitation-hydrothermal method. Results showed that As(III) c ...

Glyoxalases (GlyI & GlyII) catalyze the conversion of toxic MG into non-toxic lactic acid but their properties and functions have been overlooked in cyanobacteria. This is the first attempt to conduct a genome-wide analysis of GlyI protein (PF00903) from Ana ...
