Crossed cerebellar diaschisis after stroke detected noninvasively by arterial spin-labeling MR imaging

BMC Neuroscience, 2020
Background As a noninvasive perfusion-weighted MRI technique, arterial spin-labeling (ASL) was becoming increasingly used to evaluate cerebral hemodynamics in many studies.

Improving the Assessment of Breath-Holding Induced Cerebral Vascular Reactivity Using a Multiband Multi-echo ASL/BOLD Sequence

Scientific Reports, 2019
Breath holding (BH) is a viable vasodilatory stimulus for calculating functional MRI-derived cerebral vascular reactivity (CVR). The BH technique suffers from reduced repeatability compared with gas inhalation techniques; however, extra equipment is ...

Location in ASL [PDF]

Sign Language & Linguistics, 2012
Recent work on location variation led us to investigate whether phonetic effects influence the lowering of certain forehead located signs in American Sign Language. We found that signing speed and the location of adjacent signs did affect these forehead signs in ways that conform to general principals of coarticulation.

ASL-LEX: A lexical database of American Sign Language

Behavior Research Methods, 2016
ASL-LEX is a lexical database that catalogues information about nearly 1,000 signs in American Sign Language (ASL). It includes the following information: subjective frequency ratings from 25–31 deaf signers, iconicity ratings from 21–37 hearing non ...

Indoor Particulate Matter From Smoker Homes Induces Bacterial Growth, Biofilm Formation, and Impairs Airway Antimicrobial Activity. A Pilot Study

Frontiers in Public Health, 2020
Background: Particulate matter (PM) air pollution causes deleterious health effects; however, less is known about health effects of indoor air particulate matter (IAP).Objective: To understand whether IAP influences distinct mechanisms in the development

Argininosuccinic aciduria fosters neuronal nitrosative stress reversed by Asl gene transfer

Nature Communications, 2018
Argininosuccinate lyase (ASL) belongs to the hepatic urea cycle detoxifying ammonia, and the citrulline-nitric oxide (NO) cycle producing NO. ASL-deficient patients present argininosuccinic aciduria characterised by hyperammonaemia, multiorgan disease ...

Hemodynamic state of periictal hyperperfusion revealed by arterial spin-labeling perfusion MR images with dual postlabeling delay

eNeurologicalSci, 2018
Background: Magnetic resonance imaging (MRI), including perfusion MRI with arterial spin labeling (ASL) and diffusion-weighted imaging (DWI), are applied in the periictal detection of circulatory and metabolic consequences associated with epilepsy ...
