Biomechanical properties of normal and fibrosclerotic human cerebral arteries

Measurement of regional pulse wave velocity using very high frame rate ultrasound

“…On the other hand, the displacement at the time of the arrival of the reflection component is nearly maximum, which suggests that blood pressure at the time of arrival of the reflection component is nearly the systolic blood pressure. It is also reported that the stress-strain relationship of the arterial wall is nonlinear [32][33][34][35], and the elastic modulus of the arterial wall at higher blood pressure is larger than that at lower blood pressure. Therefore, the PWV of the reflection component (presumably at higher blood pressure) was considered to be larger than that at the forward component.…”

Bone regeneration during distraction osteogenesis: Mechano-regulation by shear strain and fluid velocity

“…fascia, vessels, etc. (Hudetz et al, 1981;Birk and Silver, 1984;Billiar and Sacks, 2000a, b). None of these effects were included in the computational model and, in combination, may be the source of discrepancy in reaction forces when compared to experimentally measured magnitudes.…”

Experimental Radiosurgery Simulations Using a Theoretical Model of Cerebral Arteriovenous Malformations

“…In reality, our adopted value for t is a fair approximation, as evidenced by inspection of light microscopic sections of cerebral AVM tissue. On the other hand, the value for E is speculative but, at least, is derived through knowledge of values of E for normal venules (1.0ϫ10 5 dyne/cm 2 ) 21 and arteries (3.0 to 5.0ϫ10 8 dyne/cm 2 ), 22 as is available in the literature. Clearly, the value of E (and to a similar extent that of t) assigned to nidus vessels and used in calculating the risk of rupture after radiosurgery could have a significant/crucial influence on whether or not an AVM is found to rupture.…”
