We sought to make the first comparisons of duplex Doppler ultrasonography-derived
measures of cerebral blood flow during exercise in young and older individuals and to …

Background Carbon dioxide is an important vasodilator of cerebral blood vessels. Cerebral
vasodilation mediated by adenosine triphosphate (ATP)-sensitive K+ channels has not been …

Using a closed cranial window system and intravital microscopy/videometry, we studied the
rat pial arteriolar (30–60 μm) responses to CO2 before and following a light/dye (L/D) …

Cerebral autoregulation ensures constant cerebral blood flow during periods of increased
blood pressure by increasing cerebrovascular resistance. However, whether this increase in …

The goal of this study was to examine effects of arginine vasopressin and angiotensin on
cerebral microvascular pressure and segmental vascular resistance. We measured pressure …

Brinzolamide is a white powder commercially formulated as a 1% ophthalmic suspension to
reduce intraocular pressure (IOP). Pharmacologically, brinzolamide is a highly specific, non …

We determined how the extra-and intracranial circulations respond to generalized
sympathetic activation evoked by a cold pressor test (CPT) and whether this is affected by …

Background: Exercise acutely lowers intraocular pressure (IOP) and raises arterial pressure.
We wondered whether the resultant increase in ocular perfusion pressure would alter retinal …

This study examined cerebral blood flow (CBF) and its regulation before and after a short-
term periodized aerobic exercise training intervention in patients with chronic obstructive …

We tested whether activation of inwardly rectifying K+ (Kir) channels, Na+-K+-ATPase, or
nitric oxide synthase (NOS) play a role in K+-induced dilatation of the rat basilar artery in …
