Cerebral oxygen extraction across different exercise intensities: Role of arterial PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_2}}}$

Experimental Physiology, EarlyView.
Abstract Stability in cerebral oxygen extraction fraction (OEF) is typically determined by alterations in cerebral blood flow (CBF). At rest, arterial partial pressure of carbon dioxide (PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$) and OEF exhibit a strong inverse relationship owing to the powerful influence of PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$

The Correlations of Clinical Outcomes and Vascular Morphology With Infarct Patterns in Middle Cerebral Arterial Occlusion

Brain and Behavior, Volume 16, Issue 2, February 2026.
For stroke caused by large vessel occlusion in M1 segment of middle cerebral artery (MCA), a tortuous and long M1 segment of contralateral MCA (cMCA) correlates with the onset of borderzone infarct. In those with a less tortuous cMCA‐M1 segment, a thin and short M1 segment correlates with large infarct.

[Moyamoya disease].

Der Radiologe, 2005
Moyamoya disease is an idiopathic progressive vasculopathy characterized by slowly progressive narrowing involving the distal internal carotid artery and the proximal circle of Willis. Collateral vessels develop to compensate for the slowly progressive stenosis.
