Multiple blood flow measurements before and after carotid artery stenting via phase-contrast magnetic resonance imaging: An observational study. [PDF]

PLoS ONE, 2018
After carotid artery stenting, the procurement of information about blood flow redistribution among brain-feeding arteries and its time trend is essential to understanding a patient's physiological background and to determine their care regimen. Cerebral

Regulation of KCa2.3 andendothelium-dependent hyperpolarization (EDH) in the rat middle cerebral artery: the role of lipoxygenase metabolites and isoprostanes [PDF]

, 2014
Background and Purpose. In rat middle cerebral arteries, endothelium-dependent hyperpolarization (EDH) is mediated by activation of calcium-activated potassium(KCa) channels specifically KCa2.3 and KCa3.1.

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

Distal anterior cerebral artery aneurysm with bilateral fetal posterior cerebral arteries and trifurcation of anterior cerebral artery

Indian Journal of Pathology and Microbiology, 2020
Developmental vascular anomalies of brain are non-modifiable risk factors for the development of aneurysms and are prone for rupture. We report one such association in a 44-year-old gentleman who succumbed to subarachnoid hemorrhage (SAH) secondary to ruptured distal anterior cerebral artery aneurysm associated with vascular anomalies in the anterior ...

Posterior Cerebral Artery [PDF]

, 2011
From the caudal division of ICA arises the PcomA from which posteriorly develops progressively the PCA, and anteriorly and caudally a connection with BA. Later in evolution in the majority of the cases the connection of the PcomA with the PCA (also called pars carotica) regresses or becomes hypoplastic, while in the connection of the BA with the PCA ...

Middle Cerebral Artery [PDF]

, 2011
The middle cerebral artery (MCA) arises in the embryogenesis as the latest branch from the cranial division of the ICA and develops to the largest artery supplying a large part of the cerebral hemispheres and basal ganglia. The development of the MCA correlates with the great extension of the cortical mantle in the mammal (Kier 1974).

Mitochondrial regulation of NADPH oxidase in hindlimb unweighting rat cerebral arteries.

PLoS ONE, 2014
Exposure to microgravity results in post-flight cardiovascular deconditioning and orthostatic intolerance in astronauts. Vascular oxidative stress injury and mitochondrial dysfunction have been indicated in this process.

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.
