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.

A Severity‐Agnostic Atrophy Pattern in Spinocerebellar Ataxia Type 3: Volumetrics from ENIGMA‐Ataxia

open access: yesMovement Disorders, EarlyView.
Background Spinocerebellar ataxia type 3 (SCA3) is a rare, inherited neurodegenerative disease characterized by progressive loss of motor coordination. Objectives We undertook a multisite magnetic resonance imaging study to profile the spatial spread of atrophy across the brain, determine whether atrophy preferentially maps onto specific functional ...

From Uncertainty to Pathogenicity: Resolving a CSF1R Variant of Uncertain Significance Using Long‐Read Transcriptomics

open access: yesMovement Disorders, EarlyView.
Abstract Background CSF1R‐related disorder (CSF1R‐RD) is a severe autosomal dominant leukoencephalopathy characterized by progressive cognitive, neuropsychiatric, and motor decline. Although genetic testing is widely available, numerous likely pathogenic variants in CSF1R frequently remain classified as variants of uncertain significance (VUS ...

Design of a LLC Resonant Converter for Powering a PEM Electrolyzer

open access: yesRE&PQJ
This paper proposes the design of a LLC resonant converter to supply a proton exchange membrane (PEM) electrolyzer. The PEM requires a low voltage with high current, a reduced output voltage ripple, and an overdamped dynamic behavior of the converter to avoid voltage overshoots.

Structural Insights Into the Function of Leishmania major Adenylosuccinate Lyase

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT One of several intriguing aspects of kinetoplastid biochemistry is the complete dependence on host purines and purine recycling due to the lack of a de novo purine biosynthesis pathway. Adenylosuccinate lyase (ASL, EC 4.3.2.2) is a key enzyme in the purine synthesis pathway responsible for the conversion of adenylosuccinate into adenosine ...

Solvent‐Induced Surface Morphology Probed by NP‐SIMS

open access: yesSurface and Interface Analysis, EarlyView.
ABSTRACT Surface morphology, that is, roughness and molecular arrangement, is known to have an impact on secondary ion mass spectra. The present study examines this issue using nanoprojectile secondary ion mass spectrometry (NP‐SIMS). NP‐SIMS involves bombarding the analyte with individual nanoparticles resolved in space and time and recording the ...
