High pulse pressure impairs cerebral artery endothelial function in young, but not old, mice

open access: yesExperimental Gerontology, 2023
One of the hallmarks of vascular aging is increased pulse pressure. This elevated pulse pressure is associated with deleterious effects on cerebral vascular function; however, it is unknown if age modulates the susceptibility to high pulse pressure.

Cerebral Arterial Fenestrations [PDF]

open access: yesInterventional Neuroradiology, 2014
Arterial fenestrations are an anatomic variant with indeterminate significance. Given the controversy surrounding fenestrations we sought their prevalence within our practice along with their association with other cerebrovascular anomalies. We retrospectively reviewed 10,927 patients undergoing digital subtraction angiography between 1992 and 2011 ...

Altered endothelin receptor expression and affinity in spontaneously hypertensive rat cerebral and coronary arteries. [PDF]

open access: yesPLoS ONE, 2013
BACKGROUND: Hypertension is associated with arterial hyperreactivity, and endothelin (ET) receptors are involved in vascular pathogenesis. The present study was performed to examine the hypothesis that ET receptors were altered in cerebral and coronary ...

Functional Arterial Anatomy of the Brain

open access: yesStroke: Vascular and Interventional Neurology, 2022
The basic patterns of the cerebral arteries development are highly conserved across vertebrates. Historical and recent studies based on human embryos, comparative anatomy, and cerebral angiographies allowed us to better understand the embryological ...

Cerebral artery segmentation based on magnetization-prepared two rapid acquisition gradient echo multi-contrast images in 7 Tesla magnetic resonance imaging

open access: yesNeuroImage, 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 ...

Posterior Cerebral Artery Infarction From Middle Cerebral Artery Infarction [PDF]

open access: yesArchives of Neurology, 2005
While it is known that posterior cerebral artery (PCA) infarction may simulate middle cerebral artery (MCA) infarction, the frequency and localization of this occurrence are unknown.To determine the frequency of PCA infarction mimicking MCA infarction and the territory of the PCA most commonly involved in this simulation.We studied 202 patients with ...

Male-female differences in upregulation of vasoconstrictor responses in human cerebral arteries. [PDF]

open access: yesPLoS ONE, 2013
BACKGROUND AND PURPOSE: Male-female differences may significantly impact stroke prevention and treatment in men and women, however underlying mechanisms for sexual dimorphism in stroke are not understood.

Posterior arterial circle of Willis anatomic variations and coronary artery dominance: is there a correlation?

open access: yesAutopsy and Case Reports, 2011
Anatomic variations and anomalies in the arteries from the circle of Willis or the heart are common, sometimes even more common than the classic morphology.

Vascularization of the Alouatta belzebul brain base [PDF]

open access: yesPesquisa 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 ...
