NeuroImage, 2020 Cerebral artery segmentation plays an important role in the direct visualization of the human brain to obtain vascular system information. On ultra-high field magnetic resonance imaging, cerebral arteries appearing hyperintense on T1 weighted (T1w ...

The Proteome of Mouse Cerebral Arteries [PDF]
Journal of Cerebral Blood Flow & Metabolism, 2014 The cerebral vasculature ensures proper cerebral function by transporting oxygen, nutrients, and other substances to the brain. Distribution of oxygenated blood throughout the neuroaxis takes place at the level of the circle of Willis (CW). While morphologic and functional alterations in CW arteries and its main branches have been reported in ...

Particularities of the imagistic diagnosis of the cervical-cerebral arteries dissection. Flow-splitter dissection [PDF]
Romanian Journal of Neurology, 2010 Background: Dissection of the cervical-cerebral arteries is an important cause of stroke in all age groups, specifically in younger population. Dissection of the cervical-cerebral arteries is produced by rupture of the intima and media layers, leading to

Vascularization of the Alouatta belzebul brain base [PDF]
Pesquisa Veterinária Brasileira, 2020 : We studied the arterial circle in the brain of five specimens of the Alouatta belzebul primate. The material had the arterial system perfused (water at 40°C), injected with stained latex (Neoprene 650), fixed in aqueous formaldehyde solution (10%) and ...

Cerebral Oxygenation in Arterial Hypoxia [PDF]
, 1976 Pronounced increases in CBF occur in arterial hypoxia (see, for example Kety and Schmidt 1948, Cohen et al. 1967). The mechanisms of this hyperemia have never been clarified but it has been postulated that a decreased extracellular pH is responsible. The following evidence has been quoted in favour of this hypothesis. First, pronounced increases in CBF

Asymmetries of total arterial supply of cerebral hemispheres do not exist
Heliyon, 2019 Background: Total blood supply to an organ, or its part, is proportional to its function. The aim of this project was to investigate whether there is a lateralisation of total functions of cerebral hemispheres by determining differences in the arterial ...

Expressional changes in cerebrovascular receptors after experimental transient forebrain ischemia.
PLoS ONE, 2012 BackgroundGlobal ischemic stroke is one of the most prominent consequences of cardiac arrest, since the diminished blood flow to the brain results in cell damage and sometimes permanently impaired neurological function.
