Contractility and Conformation [PDF]
The Journal of General Physiology, 1967 Contractility in fibers can arise from changes of macromolecular conformation caused by changes in some thermodynamic variable such as temperature, pH, or solvent composition. Illustrations are given of contractile processes in fibers and of changes in macromolecular conformation in dilute solution. These may involve order-disorder transitions, e.g. of

Substrate stiffness and VE-cadherin mechano-transduction coordinate to regulate endothelial monolayer integrity. [PDF]
, 2017 The vascular endothelium is subject to diverse mechanical cues that regulate vascular endothelial barrier function. In addition to rigidity sensing through integrin adhesions, mechanical perturbations such as changes in fluid shear stress can also ...

Suppression of lusitropy as a disease mechanism in cardiomyopathies
Frontiers in Cardiovascular Medicine, 2023 In cardiac muscle the action of adrenaline on β1 receptors of heart muscle cells is essential to adjust cardiac output to the body’s needs. Adrenergic activation leads to enhanced contractility (inotropy), faster heart rate (chronotropy) and faster ...
