Increased Serum Neurofilament Light Chain Levels in Parkinson's Disease Patients Carrying the p.A53T SNCA Mutation: Data from the Parkinson's Progression Markers Initiative Study

open access: yesMovement Disorders, EarlyView.
Abstract Background Serum neurofilament light chain (NfL) levels, a marker of axonal damage, are generally elevated in neurodegenerative conditions, but results in idiopathic Parkinson's disease (iPD) have been inconsistent. The p.A53T SNCA mutation usually leads to a severe form of PD.

Prognosis in Parkinson's Disease: An Individual Patient Data Meta‐Analysis of Six European Incidence Cohorts

open access: yesMovement Disorders, EarlyView.
Abstract Background An accurate understanding of prognosis in Parkinson's disease (PD) is important for patient information provision, personalized treatment, and clinical trial design, but most previous research has been biased towards younger, healthier patients.

Composição volátil dos defeitos intrínsecos do café por CG/EM-headspace Volatile composition of intrinsic defective coffee beans by GC/MS-headspace

open access: yesQuímica Nova, 2009
About 20% of Brazilian raw coffee production is considered inappropriate for exportation. Consequently, these beans are incorporated to good quality beans in the Brazilian market. This by-product of coffee industry is called PVA due to the presence of black (P), green (V) and sour (A) defective beans which are known to contribute considerably for cup ...

Distinct Brain Drivers and Shared Cerebello–Cortical Input in ADCY5 and SGCE Hyperkinetic Movements

open access: yesMovement Disorders, EarlyView.
Resting‐state fMRI and effective connectivity revealed distinct cerebellar–basal ganglia–cortical interactions in ADCY5 (MxMD‐ADCY5) and SGCE (MYC/DYT‐SGCE) related movement disorders. The cerebellum modulated cortex directly in MYC/DYT‐SGCE, but indirectly via basal ganglia‐cerebellar projections in MxMD‐ADCY5, which also showed reduced subthalamic ...

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 ...

Determinação de carbamato de etila em aguardentes de cana por CG-EM Determination of ethyl carbamate in sugar cane spirits by GC-MS

open access: yesQuímica Nova, 2008
A simple, specific and sensitive GC-MS procedure with ion m/z 62 was validated for the determination of ethyl carbamate (EC) in spirits. It exhibited linearity over the concentration of 30 to 600 μg/L with 30 μg/L limit of quantification. EC was detected in 70 of the 71 samples analyzed with levels from 33 to 2609 μg/L (mean level = 893 &

Frequency of ZFHX3‐Mediated Spinocerebellar Ataxia 4 in a US Undiagnosed Ataxia Cohort

open access: yesMovement Disorders, EarlyView.
Abstract Background Spinocerebellar ataxia 4 (SCA4) is a late‐onset dominant ataxia with neuropathy caused by exonic GGC repeat expansion in the ZFHX3 gene thought to originate from a Swedish founder event. The GC‐rich expansion is highly thermodynamically stable, posing challenges for standard clinical genetic testing methods.
