Effects of the intraoperative application of dexmedetomidine on hemodynamics and cerebral oxygen metabolism of patients with cerebrovascular malformations

open access: yesBIO Web of Conferences, 2017
Circulatory stability of patients with cerebrovascular malformations during the surgery is critical to their prognosis. Anesthesia-induced intubation, tumor separation, clamping and other operations may cause severe fluctuations in blood pressure and ...

Eyeballing stroke: Blood flow alterations in the eye and visual impairments following transient middle cerebral artery occlusion in adult rats

open access: yesCell Transplantation, 2020
Middle cerebral artery occlusion in rodents remains a widely used model of ischemic stroke. Recently, we reported the occurrence of retinal ischemia in animals subjected to middle cerebral artery occlusion, owing in part to the circulatory juxtaposition ...

Computational Analysis of Cardiovascular Hemodynamics [PDF]

open access: yes, 2012
The human body requires a complex circulatory system to supply nutrients to, and to remove metabolic waste products from, its tissues. Given this primary purpose, circulatory function is closely related to the hemodynamic characteristics of blood vessels.

HEMODYNAMIC MECHANISMS OF CLINICAL EFFECTS OF CYCLIC STAY OF A HUMAN IN NORMOBARIC HYPOXIC ENVIRONMENT

open access: yesМедицинский вестник Юга России, 2016
Purpose: in order to assess the adaptive hemodynamic responses formed in humans during cyclic stay (daily, for 2 hours, 15 sessions in total) in normobaric hypoxic gaseous environment with oxygen content in nitrogen of 15% (NHGE-15).Materials and methods:

High‐Resolution MRI Revealed Different Etiology‐Specific Associations With Cerebral Infarction in Adult Moyamoya Vasculopathy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective High‐resolution MRI enables detailed assessment of intracranial vessel wall pathology in moyamoya vasculopathy. We aimed to classify adult moyamoya vasculopathy etiologies using high‐resolution MRI and to examine subtype‐specific associations between high‐resolution MRI features and ischemic infarction.
