Flow-mediated dilatation has been described mainly in peripheral conduit arteries. The goal
of this study was to examine mechanisms and functional implications of flow-mediated …

Large arteries contribute to the regulation of cerebral blood flow. The goal of this study was
to examine the effects of changes in diameter of the basilar artery on blood flow to the brain …

We determined whether cerebral arterioles in vitro adjust their diameters in response to
changes in intraluminal flow rate and pressure. Intracerebral arterioles (38-to 55-μm …

Blood flow has long been hypothesized to be a primary determinant of arterial diameter
growth. To verify this hypothesis, we placed a flow-restricting silver clip on one carotid artery …

In an effort to determine whether arterial conductance vessels dilate in response to
increased blood flow stimuli, brachial artery area (cm2) and diameter (cm) were derived by …

Previous studies have demonstrated a significant pressure gradient from carotid artery to
pial or middle cerebral arteries. This pressure gradient suggests that large cerebral arteries …

Isolated, cannulated, and pressurized (100 mmHg) middle cerebral arteries from adult cats
were perfused intraluminally at rates from 0 to 4 ml/min with heated and gassed …

Studies of peripheral blood vessels in humans have focused primarily on regulation of blood
flow and vascular resistance, which are thought to reflect small vessel caliber. Recent …

An increase in blood flow can cause vasodilation through a local action on the blood vessel
wall. We examined the involvement of potassium channels in the relaxation of segments of …

Vasomotion is a rhythmic change in vascular caliber that has been described in vivo mainly
in peripheral arterioles. In this study, we have characterized vasomotion in a large artery of …
