Biopharmaceuticals, medium- and high-molecular weight biologically active macromolecules, are not easily absorbed by the small intestine, the main organ responsible for gastrointestinal absorption, ...

A new study -- one of a few to concentrate on microbes in the upper gastrointestinal tract -- shows how the typical calorie-dense western diet can induce expansion of microbes that promote the ...

To study absorption, two different approaches have been used. In vivo methods, such as measuring the disappearance of a test substance from the gut, its appearance in body fluids or its fecal output, ...
