Hence, this study aimed to investigate the effect of dyslipidemia on hepatitis B surface antigen (HBsAg) clearance and develop a nomogram model for predicting patients for whom PegIFNα therapy is indicated.

Methods: A total of 160 nucleos(t)ide analogues (NAs)- experienced chronic hepatitis B (CHB) patients treated with PegIFNα (180 µg/week) were enrolled in this study.

Small hepatitis B virus surface antigen (SHBs) induces dyslipidemia by suppressing apolipoprotein-AII expression through ER stress-mediated modulation of HNF4α and C/EBPγ.

Persistent infection with hepatitis B virus (HBV) often leads to disruptions in lipid metabolism. Apolipoprotein AII (apoAII) plays a crucial role in lipid metabolism and is implicated in various metabolic disorders. However, whether HBV could regulate apoAII and contribute to HBV-related dyslipidemia and the underlying mechanism remain unclear.

Impacts of conventional and biodegradable microplastics in maize-soil ecosystems: Above and below ground.

The increasing accumulation of microplastics (MPs) in agroecosystems has raised significant environmental and public health concerns, facilitating the application of biodegradable plastics.
