Differential Progression of Neuroinflammation in Patients with Isolated Rapid‐Eye‐Movement Sleep Behavior Disorder

Movement Disorders, EarlyView.
Abstract Background Neuroinflammation, measured using [11C](R)‐PK11195 positron emission tomography (PET), has been reported in isolated rapid‐eye‐movement sleep behavior disorder (iRBD), but its temporal progression is unknown. Objective The aim was to assess longitudinal progression of neuroinflammation in iRBD patients and its relationship with ...

A Novel High Efficiency Quasi-Resonant Converter

Energies, 2018
In this paper, a new constant-frequency quasi-resonant converter is proposed. Compared with the traditional LLC converter, the proposed converter can effectively reduce the range of the operating frequency.

Temporal Dynamics of Parkinson's Disease Tremor: Clinical and Neuroimaging Insights

Movement Disorders, EarlyView.
Abstract Background Parkinson's disease (PD) is a progressive neurodegenerative disorder clinically defined by three cardinal motor symptoms: bradykinesia, rigidity, and tremor. Although the natural history of bradykinesia and rigidity is well described, the evolution of tremor as the disease progresses remains controversial. Objectives The goal was to

Early and Progressive Spinal Cord Atrophy in Spinocerebellar Ataxia Type 1

Movement Disorders, EarlyView.
Abstract Background Spinocerebellar ataxia type 1 (SCA1) is a rare, autosomal dominant neurodegenerative disorder characterized by progressive cerebellar and brainstem degeneration. Previous studies have shown that spinal cord atrophy is also a key aspect of SCA1 neuropathology.

[18F]Fluorodeoxyglucose positron emission tomography ([18F]FDG PET) Characterizes Neurodegeneration Levels Across the α‐Synucleinopathy Continuum

Movement Disorders, EarlyView.
Abstract Background [18F]Fluorodeoxyglucose positron emission tomography ([18F]FDG PET) represents an endorsed neurodegeneration biomarker in neuronal α‐synucleinopathies. Idiopathic/isolated rapid eye movement (REM) sleep behavior disorder (iRBD) represents a prodromal stage of such disorders.

Seeing Invisible Oligomers: Rethinking α‐Synuclein Pathology Through Proximity Ligation Assay

Movement Disorders, EarlyView.
Abstract Parkinson's disease (PD) and multiple system atrophy are defined by α‐synuclein (αSYN)‐positive inclusions – Lewy bodies (LBs) and glial cytoplasmic inclusions – yet mounting evidence indicates that these inclusions represent only a fraction of disease‐relevant pathology.

LLC Resonant Converter with asymmetric PWM for hold-up time

, 2011
To narrow down the switching frequency variation range of an LLC resonant converter, asymmetric pulse-width modulation (APWM) of the hold-up time is proposed.
