Simultaneous QSM and metabolic imaging of the brain using SPICE [PDF]

Magnetic Resonance in Medicine, 2017
PurposeTo map brain metabolites and tissue magnetic susceptibility simultaneously using a single three‐dimensional 1H‐MRSI acquisition without water suppression.MethodsThe proposed technique builds on a subspace imaging method called spectroscopic imaging by exploiting spatiospectral correlation (SPICE), which enables ultrashort echo time (TE)/short ...

Imaging the Centromedian Thalamic Nucleus Using Quantitative Susceptibility Mapping

Frontiers in Human Neuroscience, 2020
The centromedian (CM) nucleus is an intralaminar thalamic nucleus that is considered as a potentially effective target of deep brain stimulation (DBS) and ablative surgeries for the treatment of multiple neurological and psychiatric disorders.

PLXDC2 siRNA‐Mediated Intervention Attenuates Microglial Senescence Through cGAS‐STING Signaling

Advanced Science, EarlyView.
PLXDC2 was identified as a microglial target in Parkinson's disease through human and mouse single‐cell analyses. Ferritin‐armed biomimetic nanovesicles delivered PLXDC2 siRNA, deferoxamine, and CeO2 nanoparticles across the blood–brain barrier, reducing cGAS‐STING activation, iron burden, oxidative stress, and senescence in microglia, thereby ...

Serum Chitotriosidase Links to Activated Glia at Chronic Active Lesion Rims in Multiple Sclerosis Brain

Annals of Neurology, EarlyView.
Objective The objective of this study was to explore the association between 18 kDa translocator protein (TSPO)‐positron emission tomography (PET)–measurable glial activation and serum chitotriosidase (CHIT1) in people with multiple sclerosis (pwMS), and its expression in postmortem MS brain tissue.
