The collaterome: A novel conceptual framework of systems biology in cerebrovascular disorders

Brain Circulation, 2015
The collaterome is the elaborate neurovascular architecture within the brain that regulates and determines the compensatory ability, response, and outcome of cerebrovascular pathophysiology.

Edaravone attenuates sustained pial arteriolar vasoconstriction independently of endothelial function after unclamping of the abdominal aorta in rabbits [PDF]

Korean Journal of Anesthesiology, 2021
Background Cerebral blood flow (CBF) has direct effects on neuronal function and neurocognitive disorders. Oxidative stress from abdominal aortic surgery is important in the pathophysiology of CBF impairment.

Circulating inflammatory biomarkers are related to cerebrovascular disease in older adults [PDF]

Neurology Neuroimmunology & Neuroinflammation, 2019
This investigation aimed at examining whether circulating inflammatory biomarkers C-reactive protein (CRP), interleukin-6 (IL6), and alpha 1-antichymotrypsin (ACT) were related to cerebrovascular disease (CVD) assessed by MRI.The study included nondemented elderly participants of a community-based, multiethnic cohort, who received baseline MRI scans ...

Arterial Steal to the Penumbra Area in Patients with Acute MCA Occlusion: A Quantitative Angiographic Analysis [PDF]

Neurointervention, 2020
Purpose In acute middle cerebral artery (MCA) occlusion, collateral vessels provide retrograde supply to the occluded territory. We hypothesized that such collateral flow reduces perfusion of the non-occluded donor region (steal effect).

Analysis of the symmetric configuration of the circle of Willis in a series of autopsied corpses [PDF]

Vojnosanitetski Pregled, 2015
Introduction. The forming of the blood vessels network configuration at the base of the brain and interconnecting of blood vessels during the embryogenesis is directly related to the phylogenetic development of the brain and brain structures.
