The Role of PC-MRI in Neurodegenerative Diseases [PDF]

Geriatrics, Gerontology and Aging
INTRODUCTION: Neurodegenerative diseases, a major public health problem, could have a vascular origin. Phase-contrast magnetic resonance imaging (PC-MRI) enables reliable, non-invasive, and rapid measurements of cerebrospinal fluid (CSF) and blood flows,

Hyperglycaemia does not increase perfusion deficits after focal cerebral ischaemia in male Wistar rats [PDF]

, 2018
Background: Hyperglycaemia is associated with a worse outcome in acute ischaemic stroke patients; yet the pathophysiological mechanisms of hyperglycaemia-induced damage are poorly understood.

Cerebral blood flow regulation and cognitive function: a role of arterial baroreflex function

Journal of Physiological Sciences, 2019
A strict adequate perfusion pressure via arterial baroreflex for the delivery of oxygen to the tissues of the body is well established; however, the importance of baroreflex for cerebral blood flow (CBF) is unclear. On the other hand, there is convincing

Hyperhomocysteinemia induced by excessive methionine intake promotes rupture of cerebral aneurysms in ovariectomized rats. [PDF]

, 2016
BackgroundHyperhomocysteinemia (HHcy) is associated with inflammation and a rise in the expression of matrix metalloproteinase-9 (MMP-9) in the vascular wall.

Sickle Cell Disease and Other Risk Factors for Pediatric Arterial Ischemic Stroke: A Systematic Review and Meta-Analysis [PDF]

Annals of Child Neurology
Purpose The incidence and mortality rates of arterial ischemic stroke (AIS) among pediatric patients have been frequently reported. While pediatric stroke can have multiple severe effects, its risk factors have not been methodically examined.
