Neurochemical Endpoints to Inform Early‐Stage Trials of Spinocerebellar Ataxia 2 and 3 in a Multisite Setting

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neurochemical levels measured by brain MR spectroscopy (MRS) have been proposed as endpoints for clinical trials in early‐stage spinocerebellar ataxia (SCA) trials. We tested their trial‐readiness by quantifying neurochemicals in three affected brain regions in early‐stage cohorts of SCA2 and SCA3, examining their reproducibility in ...

Structural Parameters of Star Clusters: Signal to Noise Effects

open access: yesOpen Astronomy, 2015
We study the impact of photometric signal to noise on the accuracy of derived structural parameters of unresolved star clusters using MCMC model fitting techniques.

Effect of the environmental parameters on the noise diffusion

open access: yes, 2006
An experimental work was carried out in an open field having 10000 m2 area purified from any noise on 121 survey stations using the central frequencies of 7 different octave bands with a single and double sources of noise. Meteorological parameters such as temperature, humidity, atmospheric pressure, velocity and direction of wind were also taken into ...

T1 Over Squared Proton Density Ratio to Characterize Multiple Sclerosis Lesions

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Differentiating remyelinated from demyelinated lesions in MS remains challenging without histological confirmation. This study introduces the T1‐to‐PD2 ratio (TPR) imaging approach and evaluates its ability to characterize MS lesions alongside other quantitative MRI (qMRI) metrics. Methods Thirty individuals with MS (mean age: 47.5 ±

Does Long‐Term Lower Extremity Strength Training in Adults With Knee Osteoarthritis and Varus Alignment Reduce Knee Joint Loading During Gait?

open access: yesArthritis Care &Research, EarlyView.
Objective We examined whether 18 months of strength training in individuals with knee varus alignment and medial tibiofemoral osteoarthritis (OA) reduced knee joint loads during walking compared to an attention control group. Methods This study was a secondary analysis of a randomized clinical trial that compared the effects of strength training to a ...

White Noises on Different Stokes Components of Six Millisecond Pulsars

open access: yesThe Astrophysical Journal
We presented measurements of jitter noise and radiometer noise for the Stokes parameters I , L , and V in six millisecond pulsars from the International Pulsar Timing Array sample, based on FAST observations.

Discordance Between Systemic Lupus Erythematosus Disease Activity Index Domain Weights and Their Association With Organ Damage Accrual

open access: yesArthritis Care &Research, EarlyView.
Objective Studies of damage accrual in patients with systemic lupus erythematosus (SLE) show associations with disease activity measured by the SLE Disease Activity Index 2000 (SLEDAI‐2K), but these associations are imperfect. SLEDAI scores are powerfully influenced by weightings (1–8) assigned to each domain.

The Effect of Noise Reduction Measures on the Perception of Railway Noise

open access: yes, 2015
The A-weighted sound pressure level is a commonly used quantity to assess the effect of noise reduction measures. However, psychoacoustic variables, in particular loudness, are assumed to better explain perceived annoyance.
