Arterial Spin Labeling Techniques 2009–2014

Journal of Medical Imaging and Radiation Sciences, 2016
Arterial spin labeling (ASL) techniques have been implemented across a diverse range of clinical and experimental applications. This review aims to evaluate the current feasibility of ASL in clinical neuroradiology based on recent improvements to ASL sequences and highlight areas for potential clinical applications.In December 2014, a literature search

Lattice Structures for Bone Replacement: The Intersection of Bone Biomechanics, Lattice Design, and Additive Manufacturing

Advanced Materials Technologies, EarlyView.
This review outlines how understanding bone's biology, hierarchical architecture, and mechanical anisotropy informs the design of lattice structures that replicate bone morphology and mechanical behavior. Additive manufacturing enables the fabrication of orthopedic implants that incorporate such structures using a range of engineering materials ...

Arterial spin labeling assessment of myometrial perfusion changes in patients with uterine fibroid and its impact on fertility

The Egyptian Journal of Radiology and Nuclear Medicine, 2021
Background Fibroids are the most common uterine tumor in the reproductive age group. These tumors although benign, their relation to infertility is still controversial. The purpose of this study is to assess the fibroid impact on fertility using arterial

Two‐Photon Polymerized Microvascular Environments for Multicellular Modeling of the Blood–Brain Tumor Barrier

Advanced Materials Technologies, EarlyView.
Modeling the blood–brain tumor barrier is challenging due to complex interactions between brain microvasculature and glioma cells. We present two‐photon polymerized 3D micro‐porous capillary‐like structures that support endothelial alignment, cytoskeletal organization, and pericyte‐endothelial‐glioma tri‐cultures.

Physiopathological implications of abnormal Arterial Spin Labeling perfusion in thrombotic microangiopathy

Thrombosis Update, 2021
Thrombotic microangiopathies are a group of clinical syndromes characterized by microangiopathic hemolytic anemia, thrombocytopenia and end-organ damage, which can compromise the central nervous system.

Postoperative Stress Accelerates Atherosclerosis Through Inflammatory Remodeling of the HDL Proteome and Impaired Reverse Cholesterol Transport

Advanced Science, EarlyView.
The study shows that noncardiac surgical inflammation rapidly disrupts HDL function and cholesterol efflux in mice and human patients. Impaired reverse cholesterol transport after surgery drives rapid lipid accumulation, NETosis, and apoptosis within atherosclerotic plaques.

Inhibition of SLC11A1‐Mediated Lysosomal Iron Accumulation in Microglia Promotes Repair Following White Matter Stroke

Advanced Science, EarlyView.
Genetic and pharmacological inhibition of SLC11A1 functioning as an H+/Fe2+ antiporter–mediated lysosomal iron accumulation in microglia promotes lysosomal lumen acidification, increases CTSD expression, enhances lysosomal myelin debris uptake and degradation, and promotes repair following white matter stroke. ABSTRACT White matter stroke (WMS) results

Determination of spin compartment in arterial spin labeling MRI [PDF]

Magnetic Resonance in Medicine, 2010
AbstractA major difference between arterial‐spin‐labeling MRI and gold‐standard radiotracer blood flow methods is that the compartment localization of the labeled spins in the arterial‐spin‐labeling image is often ambiguous, which may affect the quantification of cerebral blood flow.
