Correlation of rheoencephalography and laser Doppler flow: a rat study

open access: yesJournal of Electrical Bioimpedance, 2016
Measuring brain electrical impedance (rheoencephalography) is a potential technique for noninvasive, continuous neuro-monitoring of cerebral blood flow autoregulation in humans.

Cerebral blood flow autoregulation is impaired in schizophrenia [PDF]

open access: yes, 2017
Patients with schizophrenia have a higher risk of cardiovascular diseases and higher mortality from them than does the general population; however, the underlying mechanism remains unclear.

Impaired endothelial function of the retinal vasculature in hypertensive patients [PDF]

open access: yes, 2004
<p><b>Background and Purpose:</b> Arterial hypertension constitutes a central factor in the pathogenesis of stroke. We examined endothelial function of the retinal vasculature as a model of the cerebral circulation.</p> <p ...

Non‐Invasive Multidimensional Capacitive Sensing for In Vivo Traumatic Brain Injury Monitoring

open access: yesAdvanced Materials Technologies, EarlyView.
Single‐electrode, multidimensional capacitive sensors noninvasively assess cerebral autoregulation and compliance for traumatic brain injury monitoring. ABSTRACT Traumatic brain injury (TBI) is a major cause of death and disability, but invasive intracranial pressure (ICP) monitoring is risky, and current non‐invasive methods lack the resolution and ...

From the Gut to the Brain: Microplastic‐Associated Neurovascular Dysfunction and Implications for Stroke Risk

open access: yesAdvanced Science, EarlyView.
Chronic oral exposure to microplastics may disrupt gut microbiota homeostasis and intestinal barrier integrity, potentially engaging the gut–brain axis and systemic inflammatory responses. These alterations may be associated with impaired blood–brain barrier function, cerebral microvascular dysfunction, and enhanced endothelial inflammation, pro ...

Cerebral Autoregulation Real-Time Monitoring

open access: yesPLOS ONE, 2016
Cerebral autoregulation is a mechanism which maintains constant cerebral blood flow (CBF) despite changes in mean arterial pressure (MAP). Assessing whether this mechanism is intact or impaired and determining its boundaries is important in many clinical settings, where primary or secondary injuries to the brain may occur.

Cerebral Perfusion and Cerebral Autoregulation after Cardiac Arrest [PDF]

open access: yesBioMed Research International, 2018
Out of hospital cardiac arrest is the leading cause of death in industrialized countries. Recovery of hemodynamics does not necessarily lead to recovery of cerebral perfusion. The neurological injury induced by a circulatory arrest mainly determines the prognosis of patients after cardiac arrest and rates of survival with a favourable neurological ...

Disruption of the Blood–Brain Barrier Predicts Progression of Cerebral Small Vessel Disease White Matter Hyperintensities

open access: yesAnnals of Neurology, EarlyView.
Objective The objective of this study was to test if blood–brain barrier (BBB) disruption, detected using dynamic susceptibility contrast (DSC) imaging, would predict progression of white matter hyperintensities (WMHs) over the subsequent year in patients with chronic cerebrovascular disease. Methods The study included patients with a history of stroke

Tenecteplase Versus Alteplase for First‐Pass Reperfusion in Basilar Artery Occlusion Stroke Thrombectomy

open access: yesAnnals of Neurology, EarlyView.
Objective The first‐pass effect (FPE), defined as excellent reperfusion after a single attempt, is associated with improved outcomes in large vessel occlusion stroke. We evaluated whether intravenous tenecteplase (TNK) compared with alteplase (TPA) increases the likelihood of FPE in basilar artery occlusion (BAO).

METHOD FOR DETERMINING THE UPPER LIMIT OF CEREBRAL AUTOREGULATION IN RATS

open access: yesФармация и фармакология (Пятигорск), 2018
The main objective of the phenomenon of cerebral autoregulation is to maintain a constant cerebral blood flow rate with changes in systemic arterial pressure in the range of 50 mmH up to 150 Mmhg.
