Cerebral circulation in experimentally-induced cerebrovascular accidents
Experimental Neurology, 1969Abstract The cerebral blood-flow changes and their relation to the systemic blood pressure were studied on two experimental models of cerebrovascular accidents (intracerebral hematoma and cerebral softening). The cerebral blood flow measured with thermistores was found to be significantly increased in both hemispheres for either experimental model ...

Hydergine effect on cerebral circulation in cerebrovascular disease
Journal of the Neurological Sciences, 1971Abstract Cerebral blood flow (CBF) was measured in 10 patients with cerebrovascular disease and in 2 normal individuals using the 133Xenon injection technique. After control measurements were performed, 0.6–1.2 mg of Hydergine was given intramuscularly.

Circulating norepinephrine and cerebrovascular control in conscious humans
Clinical Physiology and Functional Imaging, 2003SummaryBackground: Cerebral vasoconstriction without concurrent changes in systemic arterial blood pressure has been observed in both normal individuals and those with idiopathic orthostatic intolerance following several minutes of postural stress when circulating catecholamines are elevated.

Circulating endothelial microparticles as a marker of cerebrovascular disease
Annals of Neurology, 2009AbstractObjectiveCirculating endothelial microparticles (EMPs) have been reported to reflect vascular damage. Detailed profiling of these blood endothelial markers may adumbrate the pathogenesis of stroke or enable determination of the risk for stroke. We investigated EMP profiles in patients at risk for cerebrovascular disease.MethodsWe prospectively ...

A Model of Indispensability of a Large Glial Layer in Cerebrovascular Circulation
Neural Computation, 2010We formulate the problem of oxygen delivery to neural tissue as a problem of association. Input to a pool of neurons in one brain area must be matched in space and time with metabolic inputs from the vascular network via the glial network. We thus have a model in which neural, glial, and vascular layers are connected bidirectionally, in that order ...

[Cerebrovascular circulation in patients with oligomenorrhea].
Akusherstvo i ginekologiia, 1993Brain hemodynamics was studied in 76 patients with oligomenorrhea aged 18 to 35 from the data of rheoencephalography. Disorders of the regional tone of brain vessels were different and related to the time of the menstrual cycle disorder; this may be explained by the degree of changes in various neuromediator mechanisms of brain circulation and ...

IDENTIFYING CIRCULATING MEDIATORS OF CEREBROVASCULAR DISEASE
2021Many current drugs for stroke act by targeting circulating molecules, yet these have not been exhaustively evaluated for therapeutic potential. A central challenge is that while many molecules correlate with stroke risk, only a subset cause stroke.
