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

open access: yesExperimental 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${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$

Extremely Rare Breakdown of the Moyamoya Vessels Resulting in Intraventricular Hemorrhage after Direct Bypass Surgery in a Pediatric Patient with Moyamoya Disease

open access: yes, 2020
Revascularization surgery is established for both ischemic and hemorrhagic moyamoya disease (MMD), although hemorrhagic complication is a serious problem especially in adult MMD patients showing postoperative hyperperfusion.

Calcium‐activated chloride channels in pericytes and their role in regulating organ blood flow

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Pericytes are microvascular mural cells with diverse roles. Contractile pericytes directly regulate local perfusion, while non‐contractile pericytes coordinate upstream vascular contractility via propagating electrical signals.

SECONDARY AND TERTIARY PROFILAXY OF THE MOYAMOYA DISEASE IN CHILDHOOD CASE PRESENTATION [PDF]

open access: yes, 2018
The Moyamoya syndrome (also known as the Moyamoya disease) consists of a series of malformations and congenital modifications of the cerebral arteries and occlusions and narrowing of the terminal carotid artery bifurcation. The term Moyamoya comes from

Diseases associated with moyamoya disease or moyamoya syndrome as well as extracerebral vascular manifestations

open access: yes, 2020
Hintergrund: Bei der Moyamoya-Erkrankung handelt es sich um eine neurovaskuläre Erkrankung, die mit progredienten Stenosierungen der intrakraniellen Anteile der Arteria carotis interna und ihrer Äste und der Bildung eines Kollateralnetzes einhergeht ...

The collateral circulation in pediatric moyamoya disease [PDF]

open access: yes, 2021
Purpose: The descriptions of collateral circulation in moyamoya have so far been a mixture of topography-based and vessels' source-based analyses. We aimed to investigate the anatomy and systematize the vascular anastomotic networks in pediatric moyamoya

Noncontrast MRI Assessment of Oxygen Metabolism in Human Calf Muscles Using VSASL and ANN‐Based GESSE

open access: yesNMR in Biomedicine, Volume 39, Issue 10, October 2026.
Workflow (Steps 1–4): Both MBF and MOEF maps were registered to a T2‐weighted fat‐suppressed structural image using rigid or affine transformations in 3D Slicer. The gastrocnemius, soleus, and tibialis anterior muscles were segmented in 3D volumes, and the resulting segmentations were used as masks to propagate to all parameter maps to extract regional

Early Impact of Childhood Opportunity on Neurocognitive Outcomes in Sickle Cell Disease

open access: yesPediatric Blood &Cancer, Volume 73, Issue 9, September 2026.
ABSTRACT Introduction Neurocognitive impairment is a well‐recognized complication of sickle cell disease (SCD) that begins early in childhood and persists across development. While cerebrovascular injury contributes substantially to risk, neurocognitive deficits are also observed in children without overt or silent cerebral infarctions, suggesting ...

Posture‐Related Regional Homogeneity Abnormalities in Cerebral Small Vessel Disease: A Multi‐Position MRI Study

open access: yesCNS Neuroscience &Therapeutics, Volume 32, Issue 9, September 2026.
Patients with CSVD showed higher upright ReHo in anterior cingulate gyrus (ACG) than NCs, and supine‐upright comparison revealed widespread ReHo alterations. Upright ACG ReHo and posture‐related ReHo changes in the hippocampus, putamen, and calcarine cortex were associated with poorer cognition and greater CSVD burden, suggesting that upright imaging ...
