Arterial elasticity, endothelial function and intracranial vascular health: A multimodal MRI study

Journal of Cerebral Blood Flow and Metabolism, 2020
Vascular dysfunctions, including arterial stiffness and endothelial dysfunction, are prevalent in hypertensive subjects. We aimed to study their relations to subclinical intracranial vascular health in this study.

Reduction of leukocyte microvascular adherence and preservation of blood-brain barrier function by superoxide-lowering therapies in a piglet model of neonatal asphyxia [PDF]

, 2019
Background: Asphyxia is the most common cause of brain damage in newborns. Substantial evidence indicates that leukocyte recruitment in the cerebral vasculature during asphyxia contributes to this damage. We tested the hypothesis that superoxide radical (

Chlamydia pneumoniae in atherosclerotic middle cerebral artery [PDF]

, 2001
Background and Purpose—Atherosclerotic middle cerebral arteries are frequent sites of thrombosis, leading to stroke. Previous studies have suggested a role for Chlamydia pneumoniae in the pathogenesis of atherosclerosis.

Influence of 100% and 40% oxygen on penumbral blood flow, oxygen level, and T2*-weighted MRI in a rat stroke model [PDF]

, 2011
Accurate imaging of the ischemic penumbra is a prerequisite for acute clinical stroke research. T2* magnetic resonance imaging (MRI) combined with an oxygen challenge (OC) is being developed to detect penumbra based on changes in blood deoxyhemoglobin ...

Use of Batroxobin in Central and Peripheral Ischemic Vascular Diseases: A Systematic Review

Frontiers in Neurology, 2021
Background and Purpose: The mechanism of action of Batroxobin included the decomposition of the fibrinogen to fibrin degradation products (FDPs) and D-dimer and mobilization of endothelial cells to release endogenous nt-PA and to promote thrombolysis ...

CEREBRAL ARTERIAL DISEASE IN CHILDREN [PDF]

American Journal of Roentgenology, 1971
Sixty-one of 176 children under the age of 14 years, who suffered an acute hemiplegia, underwent angiographic studies of the cranial vessels. This hemiplegia was not related to any intracranial mass lesion, infection, cardiac or hematologic abnormality.

What went wrong? The flawed concept of cerebrospinal venous insufficiency [PDF]

, 2013
In 2006, Zamboni reintroduced the concept that chronic impaired venous outflow of the central nervous system is associated with multiple sclerosis (MS), coining the term of chronic cerebrospinal venous insufficiency ('CCSVI'). The diagnosis of 'CCSVI' is

Arterial Stiffness and Cerebral Small Vessel Disease

Frontiers in Neurology, 2018
Background and Objective: Studies on relations between arterial stiffness and full spectrum of radiological features of cerebral small vessel disease (CSVD) are scarce. We aim to investigate the association of arterial stiffness with lacunes, white matter hyperintensities (WMH), microbleeds (CMBs), dilated perivascular spaces (PVS), and brain atrophy ...

Cerebral vasoreactivity in response to a headof-bed position change is altered in patients with moderate and severe obstructive sleep apnea [PDF]

, 2018
Obstructive sleep apnea (OSA) can impair cerebral vasoreactivity and is associated with an increased risk of cerebrovascular disease. Unfortunately, an easy-to-use, non-invasive, portable monitor of cerebral vasoreactivity does not exist. Therefore, we
