Background: The conversion of primary bile acids to secondary bile acids by the gut microbiota has been implicated in colonic inflammation. This study investigated the role of gut microbiota related bile acid metabolism in colonic inflammation in both patients with inflammatory bowel disease (IBD) and a murine model of dextran sulfate sodium (DSS)-induced colitis.
Methods: Bile acids in fecal samples from patients with IBD and DSS-induced colitis mice, with and without antibiotic treatment, were analyzed using ultraperformance liquid chromatography-mass spectrometry (UPLC-MS).

The present study aims to analyze the thermal regulation of the Ce/Ce ratio on the nanonetwork titania layer over the titanium (Ti) surface developed by the alkali-mediated surface modification approach. The effect of sequential heat treatment from 200 to 800 °C was evaluated for its surface characteristics such as morphology, phase formation, roughness, hardness, hydrophilicity, etc. Surface oxidation by temperatures up to 600 °C demonstrated a progressive increase in the Ce (CeO) content with a rutile TiO network layer over the Ti surface.

Camptothecin (CPT) exhibits potent anticancer activity, but its clinical application is limited by poor solubility and severe side effects. Hyaluronic acid (HA) is gaining attention in drug delivery systems due to its excellent biocompatibility and tumor-targeting properties. In this study, we conjugated CPT to the reducing end of ultra-low molecular weight HA to create a series of HA-decorated CPT conjugates.
