We reviewed the recent literature concerning investigations of esophageal peristaltic function. The gold standard for the assessment of esophageal peristaltic function is manometry with pH monitoring. Even with this investigation modality, however, we are in fact doing no more than estimating esophageal peristaltic function from the manometry and pH results. With esophageal fluoroscopy and scin...

We studied the peristaltic motion of MHD Jeffrey fluid through porous medium in an inclined tube under the assumption of long wavelength. Closed form solutions for velocity and pressure gradient are obtained. The effects of various emerging parameters on the pressure gradient, pumping characteristics and frictional force are discussed through graphs in detail.

Unique elastomeric rotary actuators based on pneumatically driven peristaltic motion are demonstrated. Using silicone-based wheels, these motors enable a new class of soft locomotion not found in nature, which is capable of withstanding impact, traversing irregular terrain, and operating in water. For soft robotics, this work marks progress toward providing torque without bending actuators.

Until recently, conventional magnetic resonance (MR) imaging of the pancreas was limited by motion artifacts (respiratory, vascular, and bowel peristaltic) and poor spatial resolution. Recent technique innovations in MR imaging hardware and software (fast imaging) have allowed these problems to be overcome with acquisition images similar to those obtained with spiral computed tomography (CT) (F...
