Randomized Controlled Trial Clinical Trial
Antibiotic-coated hemodialysis catheters for the prevention of vascular catheter-related infections: a prospective, randomized study.
To determine the efficacy of minocycline-rifampin-coated hemodialysis catheters in reducing catheter-related infections in patients requiring hemodialysis for acute renal failure. ⋯ The use of polyurethane hemodialysis catheters impregnated with minocycline and rifampin decreases the risk of catheter-related infection in patients with acute renal failure.

The action of smooth muscle in the intestinal wall produces tonic contractions that maintain organ dimension against an imposed load such as a bolus of food, as well as forceful contractions that produce muscle shortening to propel the bolus along the gastrointestinal tract. These functions are regulated by intrinsic electrical and mechanical properties of smooth muscle. The complex signaling process that underlies these functions is discussed in this article. We propose a model that describes the facilitation of sustained contraction of smooth muscle cells in the gut.
