Added value of arterial spin labeling magnetic resonance imaging in pediatric neuroradiology: pitfalls and applications

, 2019
Arterial spin labeling is a noninvasive, non-gadolinium-dependent magnetic resonance imaging (MRI) technique to assess cerebral blood flow. It provides insight into both tissue metabolic activity and vascular supply. Because of its non-sensitivity toward

Evaluating Vascular Hemodynamics in Cerebral Proliferative Angiopathy Using Advanced Arterial Spin Labeling MRI

Stroke: Vascular and Interventional Neurology
Cerebral proliferative angiopathy (CPA) is a rare vascular disorder that affects normal blood circulation in the brain. Although the structural changes in CPA can be characterized using standard radiologic modalities, assessing the vascular hemodynamics ...

Hydrogel Adhesives for Gastrointestinal Perforation: Design Principles and Applications

Exploration, EarlyView.
There are few reviews on hydrogel adhesives that comprehensively highlight the design principles, factors affecting adhesion, and applications for gastrointestinal (GI) perforation repair. This review outlines the mainstream design approaches of hydrogel adhesives via covalent and noncovalent molecular interactions, illustrating the underlying adhesive

Bioactive Magnesium Silicate Activating Myocardial Energy Metabolism For Infarcted Myocardium Repair

Exploration, EarlyView.
ABSTRACT The heart is a highly energy‐dependent organ, developing bioenergy‐activating biomaterials to activate myocardial adenosine triphosphate (ATP) production and restore dysregulated energy homeostasis is a promising solution for its functional recovery.

The impact of exercise on cognitive function and brain health across the lifespan: A systematic review

Ibrain, EarlyView.
This systematic review of 37 studies demonstrates that aerobic, resistance, and combined exercise enhance cognitive function and brain health across all ages. Exercise promotes neuroplasticity, upregulates brain‐derived neurotrophic factor (BDNF) and vascular endothelial growth factor (VEGF), and mitigates age‐related cognitive decline, establishing ...

Multimodal MRI and multiomics reveal high‐risk neurophenotype in brain‐gut circuits as therapeutic target for Crohn's disease

Interdisciplinary Medicine, EarlyView.
Through a translational framework combining prospective dual‐center clinical cohorts with dextran sulfate sodium‐induced colitis models, this work integrated advanced neuroimaging, multi‐omics and neuromodulation interventions to redefine the high‐risk neurophenotype as a sustained pathogenic driver rather than a mere phenomenon, proposing brain‐gut ...

Arterial spin-labeling shows cortical collateral flow in the endovascular treatment of vasospasm after post-traumatic subarachnoid hemorrhage

, 2009
We report here on the case of a patient who, 10 days prior to his admission to hospital, had suffered a bicycle accident. He presented with signs of minor dysphasia.
