For a right coronary artery, three-dimensional stress and strain distributions
at a physiological intraluminal pressure and an axial extension ratio were
computed on the basis of a two-layer elastic model. To validate the model,
curves of external radius versus pressure and of axial force versus pressure
were computed for three axial extension ratios. To analyze mechanical
properties, stress-free ... hiện toàn bộ
The transmitted light strength (TS) through a thin blood layer changes with
variation in blood flow, such as positive streaming transparency for low
hematocrits and negative streaming transparency for high hematocrits. These
phenomena are examined theoretically and experimentally. Maxwell’s equations are
solved assuming that erythrocytes are oblate spheroids to investigate these
phenomena due to f... hiện toàn bộ
Cerebral aneurysm (CA) is a socially important disease given its high prevalence
and the severity of the resultant subarachnoid hemorrhage. However, currently,
the detailed mechanisms of CA formation remain elusive. Recent experimental
findings, mainly obtained by using rodent CA models, have established the notion
that CA is formed through chronic inflammation of the bifurcation sites of
cerebral... hiện toàn bộ
