The selective sphingosine 1‐phosphate receptor 1 modulator RP101075 improves microvascular circulation after cerebrovascular thrombosis

The FASEB Journal, 2019
Sphingosine‐1‐phosphate receptor (S1PR) modulators provide protection in preclinical and clinical studies for ischemic stroke, but the influences of S1PR modulation on microvascular thrombosis remain poorly understood.

Cerebral circulation in experimentally-induced cerebrovascular accidents

Experimental Neurology, 1969
Abstract 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 ...

Regulation of the Cerebral Circulation by Arterial Carbon Dioxide.

Comprehensive Physiology, 2019
Intact, coordinated, and precisely regulated cerebrovascular responses are required for the maintenance of cerebral metabolic homeostasis, adequate perfusion, oxygen delivery, and acid-base balance during deviations from homeostasis.

Circulating soluble RAGE increase after a cerebrovascular event

Clinical Chemistry and Laboratory Medicine, 2014
The receptor for AGE (RAGE) is a key mediator in cerebral ischemia. Based on the evidence from animal studies and the presence of increased high mobility group box 1 protein (HMGB1, a RAGE ligand) in the serum of stroke patients, we hypothesized that soluble RAGE (sRAGE) increase in serum after ischemic and hemorrhagic stroke and that the levels ...

Non‐Invasive Photoacoustic Cerebrovascular Monitoring of Early‐Stage Ischemic Strokes In Vivo

Advancement of science
Early‐stage stroke monitoring enables timely intervention that is crucial to minimizing neuronal damage and increasing the extent of recovery. By monitoring collateral circulation and neovascularization after ischemic stroke, the natural recovery process

Hydergine effect on cerebral circulation in cerebrovascular disease

Journal of the Neurological Sciences, 1971
Abstract 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, 2003
SummaryBackground:  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.

Studies on Improved Model for Cerebrovascular Blood Circulation

2001
For the elastic cavity model adopted in the existing cerebrovascular hemodynamics analyzers was too simple, we developed the improved model for cerebrovascular blood circulation to describe more exactly the physiologic nature of both sides cerebrovascular blood circulation and the relation between them (Willis Circle).

[Cerebrovascular circulation in patients with oligomenorrhea].

Akusherstvo i ginekologiia, 1993
Brain 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 ...
