Changes in the gastrointestinal tract (GIT) in neonates are driven by initial enteral feedings. These are important for nutrient uptake as well as drug disposition and include motility, expansion of enzyme and transporter function, permeability, intestinal microbiome, and species-specific maturation. Some aspects of GIT function do not mature until driven by increased dietary complexity. As with the GIT, pos… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
