T1 Over Squared Proton Density Ratio to Characterize Multiple Sclerosis Lesions

Annals 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 ±

Ecophysiological Responses of White Clover - Hybrid Ryegrass Mixture to Foliar Fertilisation

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2015
The rationale of the study was to check whether the association of hybrid ryegrass with white clover owing a moderate competition capacity, and optimal foliar fertilization will provide high and stable yields by reducing conventional fertilization rates.

Quantitative MRI Uncovers Subtle Cortical Damage in Myelin Oligodendrocyte Glycoprotein Antibody‐Associated Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To determine whether myelin‐sensitive quantitative MRI reveals microstructural abnormalities in normal‐appearing cortex (NACtx) in myelin oligodendrocyte glycoprotein antibody–associated disease (MOGAD), indicating that conventional MRI underestimates remission residual cortical injury.

Stage‐Dependent β‐Synuclein Links MRI and Cognitive Decline in Alzheimer's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Synaptic degeneration drives cognitive decline in Alzheimer's disease (AD), but synaptic biomarkers are scarce. Brain‐enriched β‐synuclein emerged as a synaptic damage marker. We investigated its diagnostic, prognostic, and structural correlates across the AD continuum.

The R3 component of the blink reflex in man: a reflex response induced by activation of high threshold cutaneous afferents.

, 1989
Ten successive experiments were carried out in 10 volunteers to compare the physiological properties of R2 and R3 components of the blink reflex. The electrical activation threshold of the R3 component was found to be significantly higher than that of ...

Optimization control strategy of wide ZVS range and automatic Euler angle for bi-directional wireless power transfer system by TPS

International Journal of Electrical Power & Energy Systems
In this study, a control strategy for broad ZVS operating range and BDWPT system efficiency optimization was created. The matching requirements for using TPS (three phase shift) in a BDWPT system with a double-sided LCC compensated network are ...

Autoimmune Comorbidities as Modifiers of Phenotypic Heterogeneity in Facioscapulohumeral Dystrophy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Facioscapulohumeral dystrophy type 1 (FSHD1) shows clinical heterogeneity that is only partly explained by D4Z4 repeat unit (RU) size. Although immune and inflammatory mechanisms may contribute to disease variability, the prevalence and clinical impact of autoimmune diseases in FSHD remain unclear.
