- Abstract:
- ... Zinc bioavailability to aquatic organisms varies greatly under different pH values. In the present study, five native species in China and four common international test species were selected to investigate the influence of changing pH on acute zinc toxicity. The results showed that the higher trophic levels exhibited increasing sensitivity to zinc as pH decreased. However, when the pH value was b ...

- Abstract:
- ... MicroRNAs (miRNAs) differentially expressed in plasma were identified using microRNA sequencing (miRNA-seq), and five miRNAs were selected for validation. Potential target genes of these five miRNAs were predicted using the miRWalk3.0 database, and the overlapping portions were analyzed using the Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG) databases. Comparison of the ...

- Abstract:
- ... High arsenic (As) concentrations are found in marine clams, usually as less-toxic arsenobetaine (AsB). However, when clams were exposed to elevated As concentrations in the environments, As species distribution within them may be altered. This study aimed to determine As bioaccumulation and biotransformation in marine clams (Asaphis violascens) along As concentration gradients for 10 days. Nine tr ...
