.... The chondroitin sulfate chains are attached to the proteoglycan core proteins, most of which are attached to hyaluronic acid polymers. As we argued above, despite the fact that the chondroitin sulfate chains belonging to neighboring proteoglycans overlap, they do not significantly impede the motion...

...-dimensional studies have shown that dynamic flow conditions (e.g., pulsatile oscillatory waveforms) elicit an enhanced mechanotransductive response and elevated expression of osteoblastic proteins relative to steady flow. However, dynamic perfusion of three-dimensional scaffolds has been primarily examined...

... to model and predict the behavior under any load. Most ex vivo tests are performed within 24 h of dissection, so the tissue is still “alive.” For large elastic arteries; however, the passive mechanical behavior is attributed mostly to the very stable proteins, elastin, and collagen. If the testing...
