MOTOR DYSFUNCTION OF THE GASTROINTESTINAL TRACT

Upper gastrointestinal sensory-motor dysfunction in diabetes mellitus.

Gastrointestinal (GI) sensory-motor abnormalities are common in patients with diabetes mellitus and may involve any part of the GI tract. Abnormalities are frequently sub-clinical, and fortunately only rarely do severe and life-threatening problems occur. The pathogenesis of abnormal upper GI sensory-motor function in diabetes is incompletely understood and is most likely multi-factorial of ori...

Central apelin mediates stress-induced gastrointestinal motor dysfunction in rats.

Apelin, an endogenous ligand for APJ receptor, has been reported to be upregulated in paraventricular nucleus (PVN) following stress. Central apelin is known to stimulate release of corticotropin-releasing factor (CRF) via APJ receptor. We tested the hypothesis that stress-induced gastrointestinal (GI) dysfunction is mediated by central apelin. We also assessed the effect of exogenous apelin on...

Stenting of the Gastrointestinal Tract

Key Points  As the majority of the gastrointestinal tract consists of luminal structures, strictures can develop that result in luminal obstruction.  Stenting is being utilized commonly in human medicine to recanalize structures that have been obstructed allowing for food passage or the passage of fluids such as bile and pancreatic secretions.  Stenting of gastrointestinal tract structures n...
