A Computational Analysis for Active Flow and Pressure Control Using Moving Roller Peristalsis

Computation, 2021
Peristaltic motion arises in many physiological, medical, pharmaceutical and industrial processes. Control of the fluid volume rate and pressure is crucial for pumping applications, such as the infusion of intravenous liquid drugs, blood transportation ...

Evaluating esophageal motility beyond primary peristalsis: Assessing esophagogastric junction opening mechanics and secondary peristalsis in patients with normal manometry

Neurogastroenterology and Motility, 2021
Functional luminal imaging probe (FLIP) Panometry assesses the esophageal response to distention and may complement the assessment of primary peristalsis on high‐resolution manometry (HRM).

Optogenetic control of gut movements reveals peristaltic wave-mediated induction of cloacal contractions and reactivation of impaired gut motility

Frontiers in Physiology, 2023
Gut peristalsis, recognized as a wave-like progression along the anterior-posterior gut axis, plays a pivotal role in the transportation, digestion, and absorption of ingested materials.

Gastrointestinal Neurons Expressing HCN4 Regulate Retrograde Peristalsis

Cell Reports, 2020
Summary: Peristalsis is indispensable for physiological function of the gut. The enteric nervous system (ENS) plays an important role in regulating peristalsis. While the neural network regulating anterograde peristalsis, which migrates from the oral end

Feasibility of transabdominal electrohysterography for analysis of uterine activity in nonpregnant women [PDF]

, 2018
Purpose: Uterine activity plays a key role in reproduction, and altered patterns of uterine contractility have been associated with important physiopathological conditions, such as subfertility, dysmenorrhea, and endometriosis.
