Quantitative Real-Time MRI for the Assessment of Gastric Motility. [PDF]
J Magn Reson ImagingABSTRACT Background Current reference standards for measuring gastric emptying and motility are not considered optimal due to the time required, ionizing radiation, invasiveness, and spatial resolution. Purpose To assess gastric motility using novel real‐time dynamic magnetic resonance imaging in combination with static measurements for gastric ...

Regulated peristalsis into the acidic region of the _Drosophila_ larval midgut is controlled by a novel component of the Autonomic Nervous System [PDF]
, 2009 The underlying cellular and molecular mechanisms that regulate and coordinate critical physiological processes such as peristalsis are complex, often cryptic, and involve the integration of multiple tissues and organ systems within the organism.

Advanced Robotics Research, EarlyView.A soft robotic simulator is developed to replicate the digital removal of feces (DRF), a sensitive yet essential nursing procedure. Integrating soft actuators, sensors, and a realistic rectal model, the simulator balances functional fidelity with perceptual realism. Engineering evaluations and nurse feedback confirm its potential to enhance training in

Peristaltic transport of two-layered blood flow using Herschel–Bulkley Model
Cogent Engineering, 2018 The present article investigates the peristaltic transport of a Herschel–Bulkley fluid in an axisymmetric tube. The governing equations are solved using the long wavelength and small Reynolds number approximation.

Advanced Science, EarlyView.A healthy gut barrier shields underlying fibroblasts from luminal shear forces, illustrating that “good fences make good neighbors.” Barrier damage exposes fibroblasts to shear stress, inducing cell death and the emergence of stress‐adapted, profibrotic fibroblasts. Sustained shear exposure promotes the formation of stiff aggregates of mechanoadapative
