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 ...

In this image, red is the color of absorption. The red cells in this image are enterocytes, which line the walls of your small intestine and are responsible for absorbing nutrients from the food you ...

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 ...

This story is part of a series exploring human anatomy and physiology complexities. Each story in this collection showcases discoveries reshaping our understanding of the body's inner workings, ...

A researcher at Midwestern University led a new study showing that Western diets, high in fat and simple sugar, promote the growth of bacteria in the small intestine that increase fat digestion and ...

The small intestine is responsible for absorbing our dietary nutrients, but it also plays a role in warding off toxic chemicals and life-threatening bacteria. Yale researchers now report on the ...

Guido Hooiveld’s proof-of-concept study, examining how the small-intestine microbiota influences different blood glucose responses when people eat the same foods, will be enabled by his Global Grant ...

Higher circulating levels of insulin—a hallmark of insulin resistance—may directly stimulate breast cancer cell growth.

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, ...

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 ...
