Integrating Transcriptome and Metabolome Analyses Revealed Salinity Induces Arsenobetaine Biosynthesis in Marine Medaka ().

Marine fish exhibit elevated levels of arsenobetaine (AsB), while the impact and underlying mechanism of salinity on AsB biosynthesis remain inadequately explored. In this study, marine medaka (), typically inhabiting 30‰ high salinity, were gradually acclimated to low salinities of 20, 10, and 0‰. Following acclimation, the fish were exposed to arsenate (As(V)) in their diet for 30 days.

Shape-dependent adsorption of CeO nanostructures for superior organic dye removal.

Highly efficient removal of dye pollutants from water resources remains a great challenge. Herein, we demonstrate a new approach for the efficient removal of anionic organic dyes from wastewater using shape-dependent CeO nanostructures. It was found that the volume stoichiometry ratio of ethanol to water (EtOH/HO) was a key factor affecting the CeO nanostructures.
