Pathogenicity of Mediator Complex Subunit 27 (MED27) in a Neurodevelopmental Disorder with Cerebellar Atrophy

Advanced Science, EarlyView.
MED27 is one of the 26 subunits in the human Mediator complex (MED). Neurodevelopmental disorder‐causing MED27 genetic variants induce instability of MED, leading to disrupted DNA occupancy, altered chromatin interaction, and subsequent transcriptional dysregulation of critical downstream genes, including master regulatory transcription factors ...

MEK1/2 inhibitor U0126, but not nimodipine, reduces upregulation of cerebrovascular contractile receptors after subarachnoid haemorrhage in rats.

PLoS ONE, 2019
Vascular pathophysiological changes after haemorrhagic stroke, such as phenotypic modulation of the cerebral arteries and cerebral vasospasms, are associated with delayed cerebral ischemia (DCI) and poor outcome.

Shear Stress Targeted Delivery of Nitroglycerin to Brain Collaterals Improves Ischaemic Stroke Outcome

Advanced Science, EarlyView.
Shear‐activated nanoparticles carrying nitroglycerin selectively target high‐shear stress collateral vessels during ischaemic stroke, enhancing blood flow to at‐risk brain without systemic side effects. This novel approach significantly improves outcomes in animal models, outperforming conventional nitroglycerin delivery.

Loss of Hepatic Angiotensinogen Attenuates Diastolic Dysfunction in Heart Failure with Preserved Ejection Fraction

Advanced Science, EarlyView.
Increased hepatic angiotensinogen (AGT) abundance leads to cardiac diastolic dysfunction via the AngII‐independent pathway. Liver‐derived AGT is internalized by LRP2 in cardiac endothelial cells, subsequently contributing to myocardial diastolic dysfunction by suppressing microvascular angiogenesis via inhibiting the GATA2/Pim3 pathway.

Anomalies of the Middle Cerebral Artery

Neurologia medico-chirurgica, 2017
There are several anomalies of the middle cerebral artery (MCA) in humans, such as accessory MCA, duplicated MCA, fenestration of MCA, and duplicated origin of MCA. Recently, unfused or twig-like MCA, which indicates MCA trunk occlusion with collateral plexiform arterial network, have been reported.
