Relationship Between Neurologic Symptoms and Signs and FMR1 Genotype in Premutation Carriers

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Objectives Fragile X‐associated Tremor/Ataxia Syndrome (FXTAS) is the most severe late‐onset condition caused by a premutation in the FMR1 gene, characterized by expanded CGG triplet repeats of 55–200. Clinical presentations of FXTAS, including gait ataxia, kinetic tremor, cognitive decline, and rare Parkinsonism, are linked to ...

RNA Sequencing Resolves Cryptic Pathogenic Variants in Mitochondrial Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Mitochondrial diseases are the most common inherited metabolic disorders, characterized by pronounced clinical and genetic heterogeneity that complicates molecular diagnosis. Although DNA‐based sequencing approaches have become standard in genetic testing, up to half of patients remain without a definitive diagnosis.

Distribution Strategy of Wind Farm Active Power and Its Implementation

Kongzhi Yu Xinxi Jishu, 2013
Currently, average distribution is generally adopted for the active power control instruction of wind farms. If the wind speed differs much among wind turbines in the wind farm, the output active power of the wind farm may as well differ much from the ...

The Impact of Limiting Reactive Power Flows on Active Power Losses in Lighting Installations

Energies
Road lighting is one of the most important services provided by public entities. Entities providing such a service are interested in providing it with the lowest possible financial outlays. When planning modernization, unfortunately, one forgets about hidden operating costs, which are caused by, among others, the flow of reactive energy in the circuit.

Ofatumumab in Myelin Oligodendrocyte Glycoprotein Antibody–Associated Disease: A Comparison With Rituximab

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To evaluate the efficacy and safety of ofatumumab in patients with myelin oligodendrocyte glycoprotein antibody–associated disease (MOGAD), and compare it with rituximab. Methods We conducted a single–center, observational study including 22 MOGAD patients treated with ofatumumab and 21 treated with rituximab.
