Abstract Number ‐ 54: First Fully Automated Robotic Transcranial Doppler Optimization of Cerebral Blood Flow During Cardiac Revascularization Surgery

open access: yesStroke: Vascular and Interventional Neurology, 2023
Introduction Current technologies including EEG and near infrared pulse oximetry for non‐invasive monitoring of cerebral blood flow during cardiac surgery have proven inadequate for perioperative stroke risk mitigation. Cerebral arterial flow velocity is

A simple deep breathing test reveals altered cerebral autoregulation in type 2 diabetic patients [PDF]

open access: yes, 2018
Aims/hypothesis: Patients with diabetes mellitus have an increased risk of stroke and other cerebrovascular complications. The purpose of this study was to evaluate the autoregulation of cerebral blood flow in diabetic patients using a simple method that

Single‐Cell RNA Seq in Sydenham Chorea Shows B Cell HLA‐DR/DQ Upregulation and Plasma Cell Proteasomal Activation

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT The pathogenesis of Sydenham chorea remains unclear. We report a 10‐year‐old girl presenting with subacute chorea and mild carditis following Streptococcal throat infection. Single‐cell RNA sequencing on 30,794 peripheral immune cells from the patient and two sex‐matched controls revealed nine immune cell clusters.

Pulmonary consequences of experimentally induced stroke: differences between global and focal cerebral ischemia

open access: yesFrontiers in Physiology
IntroductionCerebral ischemia leads to multiple organ dysfunctions, with the lungs among the most severely affected. Although adverse pulmonary consequences contribute significantly to reduced life expectancy after stroke, the impact of global or focal ...

Use of real-time phase-contrast MRI to quantify the effect of spontaneous breathing on the cerebral arteries

open access: yesNeuroImage, 2022
Quantification of the effect of breathing on the cerebral circulation provides a better mechanistic understanding of the brain's circulatory system and is important in the early diagnosis of certain neurological diseases. However, conventional cine phase-

Analysis of the Changes in the Oxidation of Brain Tissue Cytochrome-c-Oxidase in Traumatic Brain Injury Patients during Hypercapnoea A Broadband NIRS Study [PDF]

open access: yes, 2011
Using broadband near-infrared spectroscopy (NIRS) and cerebral micro-dialysis (MD), we investigated cerebral cellular metabolism and mitochondrial redox states, following hypercapnoea in 6 patients with traumatic brain injury (TBI).

Moyamoya Disease and the Risk of Parkinson's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Moyamoya disease (MMD) is a rare cerebrovascular disorder characterized by the progressive narrowing of arteries at the base of the brain, forming abnormal collateral vascular networks. While vascular parkinsonism is noted in MMD, its link to Parkinson's disease (PD) has not been explored.

A time-invariant visco-elastic windkessel model relating blood flow and blood volume [PDF]

open access: yes, 2009
The difference between the rate of change of cerebral blood volume (CBV) and cerebral blood flow (CBF) following stimulation is thought to be due to circumferential stress relaxation in veins (Mandeville, J.B., Marota, J.J.A., Ayata, C., Zaharchuk, G ...

Change in Cognition Following Ischaemic Stroke

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Cognitive decline can occur following ischaemic stroke. How cognition changes over time and associations with cognitive change are poorly understood. This study aimed to explore these issues over 2 years following ischaemic stroke.

Postishemic Cerebral Function and Blood Flow

open access: yesОбщая реаниматология, 2005
The impact of massive blood loss on cerebral blood flow-function relationships was studied in rats in the postis-chemic period. Anxiety was examined in the raised cross-shaped labyrinth.
