By time-lapse, phase-contrast cinemicrography of sensory nerve fibers of young mice, isolated with their originating spinal ganglia in nutrient solution, the postulated peristaltic surface drive of the cellulifugal propulsion of the semisolid axonal column at a rate of the order of 1 mm/day (1 mum/min) could be verified and quantitatively analyzed. The pulse waves follow each other at about 30-...

Introduction: It is known that anticholinergic agents contribute to improve quality of conventional uterine MR images with suppression of intestinal motion. Similar to intestine, uterine myometrium consists of smooth muscles and rhythmical motion is known as uterine peristalsis. However, the effect of the anticholinergic agents to suppress uterine contractility has been shown to be weaker compa...

PURPOSE To explore the therapeutic potential and mechanism of chrysophanol on lipid-lowering function. METHODS Zebrafish or larvae were employed to evaluate the effect of chrysophanol on lipid-lowering. Zebrafish of 5 day post fertilization (dpf, larva) and 13-week old were fed with high-cholesterol diet or high-fat to investigate the influence of chrysophanol comparing with atorvastain and c...

BACKGROUND While there are a variety of identifiable causes of constipation, even idiopathic constipation has different possible mechanisms. Sennosides, the main laxative constituents of Daio, an ancient Kampo medicine, are prodrugs that are converted to an active principle, rheinanthrone, by intestinal microbiota. In this study, we aimed to determine the sennoside hydrolysis ability of lactic ...

In order to promote stone passage in renal colic, we must first understand normal ureteral activity and how this is affected by the presence of a stone. Measuring normal ureteral activity in humans is difficult without the use of invasive methods or techniques which in themselves may affect peristalsis. Monitoring the activity during confirmed renal colic is even more difficult and virtually im...

Individuals can function as integrated organisms only when information and resources are shared across a body. Signals and substrates are commonly moved using fluids, often channeled through a network of tubes. Peristalsis is one mechanism for fluid transport and is caused by a wave of cross-sectional contractions along a tube. We extend the concept of peristalsis from the canonical case of one...

Background/Aims Although high-resolution manometry (HRM) has the advantage of visual intuitiveness, its diagnostic validity remains under debate. The aim of this study was to evaluate the diagnostic accuracy of HRM for esophageal motility disorders. Methods Six staff members and 8 trainees were recruited for the study. In total, 40 patients enrolled in manometry studies at 3 institutes were s...

The primary theme of this communication is to employ convective condition of mass transfer in the theory of peristalsis. The magnetohydrodynamic (MHD) peristaltic transport of viscous liquid in an asymmetric channel was considered for this purpose. Effects of Ohmic heating and Soret and Dufour are presented. The governing mathematical model was expressed in terms of closed form solution express...

Introduction/Objective. Surgery is a ?gold standard? in treating the acute appendicitis pediatric patients. The aim of study was to determine effect open and laparoscopic appendectomy on postoperative recovery, return everyday activities, quality life patients operated for appendicitis. Methods. This prospective performed at Institute Children Youth Healthcare Vojvodina, over period 10 months. ...

Pacemaker cells are specialized cell types that drive biological rhythms like the heartbeat and intestinal peristalsis. What determines whether a cell functions as a pacemaker? Studies in Caenorhabditis elegans suggest that pacemaking activity may be controlled in part by microRNAs.
