Drug-induced cholestasis (DIC) is a leading cause of drug-induced liver injury post-drug marketing, characterized by bile flow obstruction and toxic bile constituent accumulation within hepatocytes. This study investigates the toxicity associated with intracellular bile acid (BA) accumulation during DIC development. Using liquid chromatography with tandem mass spectrometry (LC-MS/MS) analysis, we examined intracellular BA concentrations in human precision-cut liver slices (PCLS) following the administration of cyclosporin A and chlorpromazine, both with and without an established BA mixture.

Objective: To explore the possible mechanism of absorption of iron oxide nanoparticles into the human body through the gastrointestinal tract.
Methods: This article used Caco-2 monolayer cells as a cell model, prepared characterized iron oxide nanoparticles(Fe_2O_3 NPs) as suspensions, and intervened in Caco-2 cells. CCK-8 method, transwell method, and atomic spectrophotometer method were used to explore the effect of Fe_2O_3 NPs on the activity of Caco-2 cells and the absorption and transport of them through the Caco-2 monolayer cell model.

Article Synopsis
- The study aims to enhance understanding of the bacterial meningitis-causing diplococcus by identifying a functional protein that could be targeted for future treatments.
- Using a hypothetical protein (HP), researchers employed various bioinformatics methods and homology modeling to predict the protein's structure and function.
- Results indicated that HP is acidic and soluble, is localized in the periplasm, and Loperamide shows the best potential as a therapeutic agent by inhibiting the protein's transporter activity.
