Structural Carotid Atherosclerosis and Mild Behavioral Impairment: A Cross‐Sectional Study in a Community‐Dwelling Population

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Mild behavioral impairment (MBI) is a late‐life neuropsychiatric syndrome proposed as an early clinical manifestation of neurodegenerative disease. Vascular pathology contributes to late‐life cognitive and behavioral changes; however, its relationship with MBI remains insufficiently characterized.

Orbital Lymphatic Malformations Are Associated With Intracranial Vascular Anomalies

The Laryngoscope, EarlyView.
In this retrospective series, all seven patients with orbital lymphatic malformations had intracranial vascular anomalies consistent with cerebrofacial venous metameric syndrome and hotspot PIK3CA variants identified through tissue‐based sequencing. Five patients treated with alpelisib experienced symptom improvement within 6 months.

Mass Spectrometry Imaging–Guided Proteomics, an Emerging Frontier in Spatial Biology

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Spatial heterogeneity is a defining feature of tissue organization, yet conventional proteomic analysis provides limited information about the spatial origins of identified proteins. Spatially guided proteomics addresses this limitation by using tissue imaging techniques to select regions of interest (ROIs) for localized analysis by liquid ...

JAK2 Variant and Parkinsonian Syndromes: Coincidence or Pathophysiological Link?

Movement Disorders Clinical Practice, EarlyView.
Abstract Background JAK2 variants are a hallmark of myeloproliferative neoplasms (MPNs), including polycythemia vera and essential thrombocythemia. These disorders are often associated with thrombotic and inflammatory complications. From a movement disorder perspective, chorea is a rare but well‐recognized neurological occurrence in this context ...

Lewy Body Disease Across Aging: Clinical and Neuropathological Correlates in a Population Brain Bank

Movement Disorders, EarlyView.
Abstract Background Lewy body disease (LBD) is defined by neuronal α‐synuclein pathology, but how Braak‐staged LBD relates to mixed neuropathology and clinical manifestations within a single population‐based cohort remains incompletely characterized. This is especially relevant in cohorts enriched for younger individuals, which may better inform real ...

QQ‐Based Oxygen Extraction Fraction (OEF) Mapping in Mouse Brain: Initial Experience

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Oxygen extraction fraction (OEF) is a vital biomarker of cerebral oxygen metabolism and tissue viability. A novel OEF mapping method, QQ, which combines quantitative susceptibility mapping (QSM) and quantitative blood oxygen level‐dependent (qBOLD) (QSM + qBOLD = QQ), has demonstrated promise in detecting disease‐related OEF ...

Whole‐Brain Cerebral Microvascular Pulsatility Imaging Using Dynamic pCASL MRI With Segmented Stack‐of‐Stars Golden‐Angle Radial Acquisition

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop an efficient dynamic pseudo‐continuous arterial spin labeling (pCASL) MRI technique for whole‐brain microvascular flow pulsatility imaging. Methods The proposed technique combines pCASL with a segmented stack‐of‐stars golden‐angle radial acquisition.

In Vivo Dynamic D2O‐MRI for Quantifying Apparent CSF Water Renewal Across Ventricular and Extraventricular Compartments

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose The choroid plexus has long been regarded as the principal source of cerebrospinal fluid (CSF), yet this view remains unresolved. We developed a dynamic indirect D2O MRI approach to quantify regional apparent CSF water renewal in vivo in rats at 9.4 T.

Accelerated Motion‐Compensated Diffusion‐Weighted pCASL Using Subspace Low‐Rank Reconstruction for Quantification of BBB Water Exchange and Permeability

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop an accelerated motion‐compensated diffusion‐weighted pseudo‐continuous arterial spin labeling (MCDW‐pCASL) method using a spatial subspace low‐rank reconstruction method for efficient quantification of blood–brain barrier (BBB) water exchange (kw) and permeability (PSw).
