With a damped-oscillation rheometer, changes in the rheological properties,
i.e., logarithmic damping factor (LDF) and period, as obtained from a
damped-oscillation curve, were monitored during the coagulation of blood. In our
earlier studies, the time of onset of coagulation (Ti) of the blood sample was
only determined from the change in LDF. When coagulation of the blood and
sedimentation of ery... hiện toàn bộ
Inhibition of stretch-activated ion channels on endothelial cells disrupts nitric oxide-mediated arterial outward remodeling Tập 24 - Trang 77-83 - 2011

Outward arterial remodeling is a physiological response to accommodate
chronically elevated blood flow and requires endothelial cells (ECs) and
expression of endothelial nitric oxide synthase (eNOS). ECs may sense elevated
flow via stretch-activated ion channels (SACs). We evaluated the role of SACs in
regulation of flow-induced arterial expansion and eNOS expression by ECs. A
high-flow environmen... hiện toàn bộ

This article focuses on the effects of segmentation on cerebral aneurysm's
morphological parameters and on blood flow patterns computed using computational
fluid dynamics. Segmentation is a non-negligible source of uncertainty that may
have a consequent impact on the morphological assessment and the resulting
hemodynamical simulations, the latter potentially being a key element in the
decision-mak... hiện toàn bộ
