Structural and Functional Differences Between Porcine Aorta and Vena Cava
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Elastin and collagen fibers are the major load-bearing extracellular matrix (ECM) constituents of the vascular wall. Arteries function differently than veins in the circulatory system; however as a result from several ...
An Experimental and Modeling Study of the Viscoelastic Behavior of Collagen Gel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The macroscopic viscoelastic behavior of collagen gel was studied through relaxation time distribution spectrum obtained from stress relaxation tests and viscoelastic constitutive modeling. Biaxial stress relaxation tests ...
Mechanical Properties of Arterial Elastin With Water Loss
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Elastin is a peculiar elastomer in that it requires water to maintain resilience, and its mechanical properties are closely associated with the immediate aqueous environment. The bulk, extra- and intrafibrillar water plays ...
Contribution of Collagen Fiber Undulation to Regional Biomechanical Properties Along Porcine Thoracic Aorta
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As major extracellular matrix components, elastin, and collagen play crucial roles in regulating the mechanical properties of the aortic wall and, thus, the normal cardiovascular function. The mechanical properties of ...
MMP12 Deletion Preferentially Attenuates Axial Stiffening of Aging Arteries
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Arterial stiffening is a hallmark of aging, but how aging affects the arterial response to pressure is still not completely understood, especially with regard to specific matrix metalloproteinases (MMPs). Here, we performed ...
