Apoptosis in HepG2 cells induced by zinc pyrithione via mitochondrial dysfunction pathway: Involvement of zinc accumulation and oxidative stress.

Zinc pyrithione (ZPT) is widely used as a substitute booster biocide for tributyltin and is also an additive to antidandruff shampoos and medical cosmetic products. ZPT and pyrithione have been detected in different environmental matrices and biota, suggesting that it may pose health threats to aquatic organisms and even humans. The present study used HepG2 cells, a human hepatoma cell line, to study the hepatotoxicity of ZPT (0.

A framework for the assessment of the spatial and temporal patterns of threatened coastal delphinids.

The massively accelerated biodiversity loss rate in the Anthropocene calls for an efficient and effective way to identify the spatial and temporal dynamics of endangered species. To this end, we developed a useful identification framework based on a case study of locally endangered Sousa chinensis by combining both LEK (local ecological knowledge) evaluation and regional boat-based survey methods. Our study investigated the basic ecological information of Sousa chinensis in the estuaries of eastern Guangdong that had previously been neglected, which could guide the future study and conservation.
