Widespread exposure to endocrine disruptors is associated with metabolic dysfunction and reproductive toxicity. Tetrahydrocurcumin (THC) has attracted attention as it offers protection against obesity and metabolic disorders due to its potent antioxidative and diverse biological properties but its influence and underlying mechanism of action on adipose tissue function and DEHP-induced testicular injury remain unknown. Our results showed that THC (100 mg kg day) administration for 27 weeks enlarged adipocytes while attenuating macrophage infiltration and IL-6 expression in the adipose tissue of male C57BL/6J mice exposed to 5 mg kg day of DEHP.

Institute of Ocean Technology and Marine Affairs, National Cheng Kung University, No. 1, University Road, Tainan City 701401, Taiwan.

Despite the adsorption of microplastics (MPs), the precise quantification of their concentrating effect on persistent organic pollutants (POPs) remains uncertain. Therefore, in this study, POPs in MPs, POPs in suspended particulate matter (SPM), and dissolved POPs in seawater were distinguished to quantify the enrichment factor (EF) for characterizing the concentrating effects of MPs and SPM on POPs. The results showed that the logarithm of EF (log EF) for POPs in MPs was 5.
