horbar; This review shows that numerous neuropeptides and hormones are involved in the regulation of intestinal transit. Many gastrointestinal hormones known to act on smooth muscle to influence muscle contractility also play a role in the genesis of abrupt changes associated with alimentary behaviour. In many monogastrics and ruminants, the cyclic occurrence of the migrating motor complex (MMC...

BACKGROUND Gastrointestinal (GI) disturbances are often reported by long distance runners and are more common in women, particularly after prolonged high intensity exercise. OBJECTIVES To determine whether these symptoms could be associated with alterations in GI motility. METHODS Small bowel and colonic transit were measured using pH telemetry in a group of 11 female athletes (age 22 to 53...

The influence of a simulated digestive process on some biochemical and biological aspects of strawberry grape (Vitis labrusca) was investigated. The amount of total polyphenols and anthocyanins as well as the antioxidant power were evaluated. Results evidenced that the simulated gastrointestinal transit caused a decrease of the polyphenols content and total anthocyanins; these last, however, we...

INTRODUCTION Intestinal manipulation (IM) during abdominal surgery results in intestinal inflammation leading to hypomotility or ileus. Mast cell activation is thought to play a crucial role in the pathophysiology of postoperative ileus (POI). However, this conclusion was mainly drawn using mast cell-deficient mouse models with abnormal Kit signaling. These mice also lack interstitial cells of ...

Measurement of colon transit time is the most basic and primary tool in evaluating disorders of colonic motility. In particular, it is helpful in pathologic diagnosis and for planning management in patients with constipation. Several techniques for measuring colon transit time currently exist. The standard measurement of colon transit time has been performed using radioopaque marker test. The r...
