Effects of Laryngeal Restriction on Pharyngeal Peristalsis and Biomechanics: Clinical Implications [PDF]

, 2016
To date, rehabilitative exercises aimed at strengthening the pharyngeal muscles have not been developed due to the inability to successfully overload and fatigue these muscles during their contraction, a necessary requirement for strength training.

Biomechanical Study of Peristalsis -Simulation of Peristalsis in Case of Fluid Contents-

Journal of Robotics and Mechatronics, 1994
The peristalsis, commonly observed in animals'small intestines, serves as a skillful transport of the intraluminal contents. It is supposed that a neural control mechanism for peristalsis is immanent in the intestines, but the structure has not yet been made clear.

A Microbial Lipid‐ATP Synthase Axis Fuels NK Cell Antitumor Activity

Advanced Science, EarlyView.
This study focuses on the mechanism by which gut microbiota‐derived outer membrane vesicles (OMVs) regulate NK cell antitumor activity. B. intestinalis is identified to decrease extra‐intestinal tumor growth via its OMVs enriched in sphingosine (SP).

Quinine blocks 5-HT and 5-HT3 receptor mediated peristalsis in both guinea pig and mouse ileum tissue [PDF]

, 2011
Introduction. Quinine is commonly used to treat malaria; however one of the principal side effects is gastrointestinal disturbances (White, 1992). 5-HT3 receptors modulate gut peristalsis (Chetty et al., 2006), and, as quinine has been shown to act as a ...

Intestinal Source Control of Lipid Metabolism by Enzyme‐Probiotic Encapsulated, Spatiotemporal Crosslinked, and Small Intestine‐Adhesive Hydrogel Microspheres

Advanced Science, EarlyView.
A thiol‐modified alginate hydrogel microsphere‐encapsulated enzyme‐probiotic biohybrid (AKK‐COD) system has been developed to address the spatiotemporal delivery and colonization challenges of small intestine‐targeted probiotic for lipid metabolism regulation. The system exerts sequential functions of intragastric protection, small intestinal adhesion,

A Worm‐Inspired Origami Robot with Multimodal Locomotion for Adaptive Mobility in Complex Pipeline Environments

Advanced Science, EarlyView.
An origami worm‐inspired robot achieves multimodal locomotion in confined pipelines through mechatronic integration that embeds actuation, control, and communication within each origami module. Large, reversible configuration and dimensional changes enable 25 gaits synthesized by a unified framework across peristaltic, inchworm, and wheel‐rolling modes

Novel insights into mechanisms of inhibition of colonic motility by loperamide

Frontiers in Neuroscience
BackgroundIt is well known that opiates slow gastrointestinal (GI) transit, via suppression of enteric cholinergic neurotransmission throughout the GI tract, particularly the large intestine where constipation is commonly induced. It is not clear whether

Changes in pressure waves after endoscopic intervention in patients with achalasia: A focus on peristaltic recovery of the esophageal body

The Turkish Journal of Gastroenterology, 2016
Background/Aims: We conducted the present study to investigate the recovery of peristalsis of the esophageal body and evaluate the pressure changes observed on manometry before and after endoscopic intervention. Materials and Methods: Forty-five patients

Electrohydraulic Folding Ring Actuators for Radial Contraction

Advanced Science, EarlyView.
This work presents an Electrohydraulic Folding Ring Actuator that combines high‐performance electrohydraulic actuation with origami‐inspired folding geometry to achieve constricting radial actuation. This integration yields significant inner lumen constriction, alongside a gripping force capable of holding objects exceeding four times the actuator's ...
