26 Δεκ 2019 · These arteries progressively lose their low-stretch bearing component, shifting load to stiffer matrix components (collagen). At the same time, arteries also lose some of their longitudinal elasticity and geometry, leading to elongation and increased tortuosity.
1 Αυγ 2018 · Elastin is an extracellular matrix (ECM) protein with a unique biochemical structure that provides entropic elasticity, allowing the large arteries to reversibly expand and relax with every cardiac cycle.
Elasticity in Arteries: A similar combination of rubbery and stiff materials creates common mechanical properties in blood vessels of vertebrates and some invertebrates.
CONSTANT ELASTICITY OF THE ARTERIES. YOUNG'S MODULE AS A PREDICTIVE FACTOR IN. THE PREVENTION OF ARTERIAL DISEASE. AUTHORS, Horia BUZDUGA. Teodor BUCUR. COORDINATOR,
1 Φεβ 2002 · A simplified model of arterial elasticity has been used in many studies in which measurements are confined to the circumferential direction, and elastic non‐linearity is treated by defining incremental elastic properties over a limited region of the stress strain curve that is taken to be linear (for instance, that corresponding to the part ...
the elastic properties, particularly of large arteries, are impaired in the presence of cardiovascular disease and risk factors such as cigarette smoking, hypertension, diabetes and ageing. Evidence is also emerging that treatment of these risk factors
2 Φεβ 2018 · In this review, we summarize the biochemistry of elastin and elastic fiber assembly process. We discuss measures of passive arterial mechanics that are affected by elastin amounts, elastic fiber integrity, and cross-linking.
