Reversible stress softening in layered rat esophagus in vitro after potassium chloride activation
- BiologyBiomechanics and modeling in mechanobiology

The present study provides a method for computation of the stress–strain distribution throughout the wall and the mechano‐sensory interaction in the human oesophagus that may be useful for understanding of mechanoreceptor responses and generation of symptoms in visceral organs in health and in disease.

The aim of the present study was to determine the geometric configuration and morphometric dimensions in the rabbit oesophagus during luminal pressure loading and the data obtained will be useful for further modelling of the mechanics of the oesphagus.

Activation of ROK by KCl or CCh increased passive stiffness softened by muscle strain and thereby attributed to cross-links that remained stable during tissue incubation in a calcium-free solution.

Since strain softening effects were significantly greater than viscoelastic effects, it is concluded that history-dependent changes in jejunal stiffness are more likely to involve alterations to elastic rather than viscous structures in the tissue.

The stimulus-response functions provided evidence for the existence of low- and high-threshold mechanoreceptors in the human duodenum and suggested that high-Threshold receptors are nonadapting.

A model and experimental setup was developed for determination of elastic moduli in the two layers in circumferential direction and a good agreement was found between the measured elastic modulus of the intact esophagus and the elasticModulus computed from the elastic modules of the two separated layers.
Strain softening in rat left ventricular myocardium.

The preconditioning behavior of the myocardium is better explained by strain softening rather than viscoelasticity and may be due to damage to elastic components, rather than the effect of viscous tissue components.
