Because biopharmaceuticals are medium- and high-molecular-weight, biologically active macromolecules, they are not easily absorbed by the small intestine, resulting in a bottleneck for oral ...

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 ...

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

DURING its absorption by the small intestine a substance leaves the bowel lumen, traverses the epithelial lining, passes through the connective-tissue stroma of the lamina propria and enters terminal ...

This film explores the complex process of human digestion, detailing how food is broken down into molecules by the digestive system. It follows the journey of food from the mouth, where it is chewed ...

The present study reports the successful management, nutritional requirements and absorptive capacity in a seventeen-year-old boy who has to date survived for more than two years since massive ...

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

Although the vast majority of research on the gut microbiome has focused on bacteria in the large intestine, a new study--one of a few to concentrate on microbes in the upper gastrointestinal ...
