Turning Slowly Predicts Future Diagnosis of Parkinson's Disease: A Decade‐Long Longitudinal Analysis

open access: yesAnnals of Neurology, EarlyView.
Objective Wearable technology allows accurate measurement of turning while walking, with cross‐sectional studies indicating that difficulty turning presents even in preclinical phases of Parkinson's disease. The aim of our study was to quantify rate of change of turning performance in a cohort of older adults, and test whether turning decline can ...

Enhanced Resolution in EPR Spectroscopy Using para‐Hydrogen Matrices

open access: yesAngewandte Chemie International Edition, EarlyView.
We demonstrate the advantageous properties of solid para‐hydrogen (p‐H2) matrices for electron paramagnetic resonance (EPR) spectroscopy by investigating the 2,2,6,6‐tetramethylpiperidinyloxyl (TEMPO) radical and an in situ generated P‐centered mono‐radical.
