The paper develops a UHPLC-MS/MS assay to quantify 21 steroids in plasma, adipose tissue, and fecal samples with high sensitivity and accuracy.

This study links gut transit time, inferred from stool consistency, to microbial metabolites and microbiota in infants, showing associations with breastfeeding, bile acid metabolism, and short-chain fatty acids.

This study examines how human milk metabolites relate to the infant gut microbiome and metabolome over time, finding time-dependent associations and differential influences based on dietary changes.

The paper uses a colon simulator to study microbial lipid shifts in the gut and validates findings using human samples.
