Diagnostic Potential of Pulsed Arterial Spin Labeling In Alzheimer's Disease

open access: yesFrontiers in Neuroscience, 2016
Alzheimer’s disease (AD) is the most common cause of dementia. Although the underlying pathology is still not completely understood, several diagnostic methods are available. Frequently, the most accurate methods are also the most invasive.

ASL-BIDS, the brain imaging data structure extension for arterial spin labeling

open access: yesScientific Data, 2022
Arterial spin labeling (ASL) is a non-invasive MRI technique that allows for quantitative measurement of cerebral perfusion. Incomplete or inaccurate reporting of acquisition parameters complicates quantification, analysis, and sharing of ASL data ...

Intrinsically Mitochondria‐Targeting Nanozyme via Coordination‐Assembly of Natural Quercetin for Cascade Antioxidant Therapy of Cerebral Ischemia‐Reperfusion Injury

open access: yesAdvanced Science, EarlyView.
This study uncovers that quercetin naturally targets mitochondria. By coordinating quercetin with Fe3+, we engineer an ultrasmall cascade nanozyme (MCN) with superoxide dismutase‐catalase activities. MCN crosses the damaged blood–brain barrier, scavenges mitochondrial ROS, prevents mitochondrial DNA leakage, and blocks the cGAS‐STING pathway, thereby ...

Grading of skull base meningiomas by combined perfusion: arterial spin labeling and T2* dynamic susceptibility perfusion

open access: yesThe Egyptian Journal of Radiology and Nuclear Medicine
Background Conventional MRI has no distinction between high- and low-grade meningiomas, which has a crucial for choice of therapeutic plan, especially skull base meningiomas which need more meticulous endoscopy-approached surgery.

Skeletal Muscle Microvascular Flow in Progressive Peripheral Artery Disease Assessment with Continuous Arterial Spin-Labeling Perfusion Magnetic Resonance Imaging

open access: yes, 2010
Objectives We present the novel application of continuous arterial spin- labeling (CASL) magnetic resonance imaging ( MRI) for the measurement of calf muscle perfusion in subjects with progressive peripheral arterial disease (PAD).

Cholesterol Laundry of Cell Membrane and Fatty Liver by Detergent Liposomes to Improve Anti‐Cancer Drug Responsiveness of Patient Liver Tissues

open access: yesAdvanced Science, EarlyView.
Cholesterol‐enriched plasma membranes in hepatocellular carcinoma impede drug penetration. Cholesterol (+)‐liposomes act as membrane‐specific detergents, extracting cholesterol and reducing barrier function without cytotoxicity. Following endocytosis, cholesterol transfers from endosomes to liposomes and is metabolized in the ER.

Additional Role of 3D ASL Perfusion in Skull Base Lesions

open access: yesIndian Journal of Radiology and Imaging
Background Arterial spin labeling (ASL) perfusion imaging is widely used since its main advantage is that no intravenous contrast is needed.

Prediction of early reperfusion from repeated arterial spin labeling perfusion magnetic resonance imaging during intravenous thrombolysis

open access: yes, 2022
S.247-250Background and Purpose There are few in vivo data on the pathophysiology of reperfusion during systemic thrombolysis. We monitored the time course of cerebral perfusion changes in patients during thrombolysis with repeated arterial spin labeling
