The progress of food in the gastrointestinal (GI) tract is driven by a peristaltic motion generated muscle belt surrounding GI tract. In turn, response intestinal epithelial cells to stresses affects dynamics structure. this work, we study effect cyclic stretching (0.125 Hz, 10% strain) on spatial organization epithelium using deposited flat elastomeric substrate mimic vitro. A confluent monola...

The capacity of ureteral stents to enhance the conveyance of urine from kidney to bladder is the critical function for patients that require them. The flow path in and around the stent is not a trivial one, particularly if some elements of peristalsis are present in the ureter. This paper details a numerical flow simulation for an axially symmetric stented ureter segment. The flow of urine thro...

A precise analysis and diagnosis of colon motility dysfunctions with current methods is almost unachievable. This makes it extremely difficult for the clinical experts to decide for the right intervention such as colon resection. The use of Cine MRI for visualizing the colon motility is a very promising technique. In addition, if image segmentation and qualitative motion analysis provide the ne...

An in vitro simulation system was developed to study the effect of an infant's peristaltic tongue motion during breastfeeding on oral rapidly disintegrating tablets in the mouth, for use in rapid product candidate screening. These tablets are being designed for use inside a modified nipple shield worn by a mother during breastfeeding, a proposed novel platform technology to administer drugs and...
