Penn/Wistar Study Finds ‘Sweet Spot’ Where Tissue Stiffness Drives Cancer’s Spread
Penn/Wistar Study Sweet Spot Tissue Stiffness Cancer’s Spread
2017/3/14
In order for cancer to spread, malignant cells must break away from a tumor and through the tough netting of extracellular matrix, or ECM, that surrounds it. To fit through the holes in this net, thos...
The Acute Effect of Local Vibration As a Recovery Modality from Exercise-Induced Increased Muscle Stiffness
Supersonic shear imaging vibratory massage biceps brachii barbell curl exercise muscle passive stiffness
2016/3/11
Exercise involving eccentric muscle contractions is known to decrease range of motion and increase passive muscle stiffness. This study aimed at using ultrasound shear wave elastography to investigate...

A New Approach to Modeling Vertical Stiffness in Heel-Toe Distance Runners
Leg stiffness modeling leg spring
2015/3/11
Various models have been used to describe distance running technique. Among these, the mass-spring model is fairly simple to use and apply, but when employed as a model, does not predict vertical forc...
Effects of Collagen Gel Stiffness on Cdc42 Activities of Endothelial Colony Forming Cells during Early Vacuole Formation
