Distribution Map of Peristaltic Waves in the Chicken Embryonic Gut Reveals Importance of Enteric Nervous System and Inter-Region Cross Talks Along the Gut Axis

Frontiers in Cell and Developmental Biology, 2022
Gut peristaltic movements recognized as the wave-like propagation of a local contraction are crucial for effective transportation and digestion/absorption of ingested materials.

Intelligent computing for the double-diffusive peristaltic rheology of magneto couple stress nanomaterials

Nanotechnology Reviews, 2023
In nanofluids, the effect of convection in the presence of double diffusivity on a magneto couple stress fluid with the peristaltic flow of a model in a non-uniform channel (MCSFM) is reviewed in this article.

Separated Flow Through a Gap Between Two Coaxial Peristaltic Tubes

IEEE Access, 2022
A peristaltic endoscope is a device that could locomote through curving and tortuous spaces where it has many real-life applications in different disciplines e.g., in the field of medicine, it helps in the process of catheterization in curved tubes which

Thermally conductive electro-osmotic propulsive pressure-driven peristaltic streaming flow study with a suspended nanomaterial in a micro-ciliated tube

Frontiers in Materials, 2022
This article focuses on the peristaltic flow of carbon nanoparticle-suspended nanofluids under the influence of electroosmosis. The flow is considered inside a vertical tube with ciliated boundary walls.

Chemical peristalsis [PDF]

Proceedings of the National Academy of Sciences, 2005
Molecules that emulate in part the remarkable capabilities of protein motors were recently chemically synthesized. A promising approach is based on physically interlocked macromolecular complexes such as rotaxanes and catenanes. Using the latter, Leigh et al . [Leigh, D. A., Wong, J. K.

Visible intestinal peristalsis [PDF]

BMJ Case Reports, 2013
A 52-year-old man who had a history of recurrent constipation presented with an intermittent nausea and vomiting that started 1 day prior. He had a history of Nissen fundoplication for the repair of a hiatus hernia. He also had congenital mental retardation and was not unable to fully explain …

Entropy Generation via Ohmic Heating and Hall Current in Peristaltically-Flowing Carreau Fluid

Entropy, 2019
The core objective of the present study is to examine entropy generation minimization via Hall current and Ohmic heating. Carreau fluid considerations interpret the unavailability of systems’ thermal energy (for mechanical work).

Study of Heat and Mass Transfer in Electroosmotic Flow of Third Order Fluid through Peristaltic Microchannels

Applied Sciences, 2019
An analysis is carried out to evaluate the effects of heat and mass transfer in an electro-osmotic flow of third order fluid via peristaltic pumping. Solutions are derived for small wave number and Peclet number.

Accelerometer-Based Assessment of Intestinal Peristalsis: Toward Miniaturized Low-Power Solutions for Intestinal Implants

IEEE Journal of Translational Engineering in Health and Medicine, 2018
Intestinal electrical stimulation via implants is already used to treat several disorders like constipation or incontinence. Stimulation parameters are most often empiric and not based on systematic studies.
