Natural Killer Subset Changes and Vascular Endothelial Growth Factor‐A Plasma Profile in Progressive Supranuclear Palsy: The NKscape Study

open access: yesMovement Disorders, EarlyView.
Abstract Background Emerging evidence implicates neuroinflammation in progressive supranuclear palsy (PSP) pathophysiology, with elevated cyto‐chemokines suggesting natural killer (NK) cell involvement. Methods We characterized peripheral NK in PSP (N = 11) versus Parkinson's disease (PD, N = 10) and healthy controls (HC, N = 8) at both ...

Progression of Motor and Cognitive Functions in Isolated REM Sleep Behavior Disorder: A 7‐Year Prospective Matched Cohort Study

open access: yesMovement Disorders, EarlyView.
Abstract Background Although clinical markers (eg, motor and cognitive impairment) in isolated rapid eye movement sleep behavior disorder (iRBD) are associated with faster phenoconversion, their longitudinal trajectory patterns (linear or nonlinear) remain unclear.

Multi‐Targeting Ligands as Prospective Therapeutics for Alzheimer's Disease, a Prevalent Neurodegenerative Disorder: Mechanistic Insights, Emerging Targets and Drug Discovery Campaigns

open access: yesMedicinal Research Reviews, EarlyView.
ABSTRACT Alzheimer's disease (AD) is a debilitating neurodegenerative condition characterized by progressive cognitive impairment, memory deterioration, and neuronal dysfunction. Its complex pathophysiology involves multiple interlinked processes, including amyloid‐β (Aβ) aggregation, tau hyperphosphorylation, oxidative stress, neuroinflammation ...

Imaging Venous Transit Time and Blood–Brain Barrier Permeability of the Deep Brain

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Imaging of venous vessels with advanced pulse sequences allows the assessment of important hemodynamic parameters. Previous work has measured venous transit time (VTT) and blood–brain barrier (BBB) water permeability in cortical tissue.

Ultrafast fMRI Detects Age‐Related Changes in Harmonics of Cardiac Pulsations in the Brain at 7 T

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Aging impacts pulsatility of blood vessels in the brain, reflecting vascular health. Resolving characteristics of cardiac pulsatility requires faster acquisitions than traditional fMRI. An ultrafast fMRI method was developed and applied to sample several harmonics of cardiac pulsations at 7 T.

Quantifying Cardiac, Respiratory, and Low Frequency Components of CSF Motion From fMRI Inflow Effects

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Cerebrospinal fluid (CSF) flow oscillations have emerged as a potentially important marker related to brain clearance, but their acquisition often relies on specialized imaging MRI sequences. The purpose of this work was to enable quantitative assessment of CSF flow associated with cardiac, respiratory, and low‐frequency cycles using ...
