Discovery and Treatment of Action Potential‐Independent Myotonia in Hyperkalemic Periodic Paralysis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Hyperkalemic periodic paralysis (hyperKPP) is characterized by attacks of transient weakness. A subset of hyperKPP patients suffers from transient involuntary contraction of muscle (myotonia). The goal of this study was to determine mechanisms causing myotonia in hyperKPP.

Quantitative Iron Measurements in the Basal Ganglia of NBIA Patients Using QSM: Insights From a Tertiary Center

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neurodegeneration with brain iron accumulation (NBIA) comprises rare genetic disorders characterized by predominantly extrapyramidal symptoms and iron deposition in the basal ganglia. Conventional magnetic resonance imaging (MRI) detects qualitative changes but cannot accurately quantify iron accumulation. Quantitative susceptibility

[Cu3(C6Se6)]n: The First Highly Conductive 2D π–d Conjugated Coordination Polymer Based on Benzenehexaselenolate

Advanced Science, 2019
Nanocrystals of a 2D π–d conjugated copper bis(diselenolene) coordination polymer (Cu‐BHS, BHS = benzenehexaselenolate) are synthesized via a simple homogeneous reaction between cupric ions and benzenehexaselenol (H6BHS).

Surface and bulk components of electrical conductivity in the (presumably special topological) Kondo insulator SmB6 at lowest temperatures

, 2014
Samarium hexaboride (SmB6) has recently been considered to be a topological Kondo insulator (TKI), the first strongly correlated electron system to exhibit topological surface conduction states.

Kondo insulator SmB6 under strain: surface dominated conduction near room temperature [PDF]

, 2017
SmB6 is a strongly correlated mixed-valence Kondo insulator with a newly discovered surface state, proposed to be of non-trivial topological origin. However, the surface state dominates electrical conduction only below T* ~ 4 K limiting its scientific ...

Nerve Excitability in Asymptomatic Carriers and Amyotrophic Lateral Sclerosis Patients With C9orf72

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective We investigated the effects of C9orf72 mutation carriership on peripheral nerve excitability in asymptomatic individuals from families with a history of C9orf72 amyotrophic lateral sclerosis (ALS) and patients. Methods We included 47 asymptomatic individuals from families with a history of C9orf72 ALS, of whom 23 were carriers (C9 ...

New Insights into the Development and Morphogenesis of the Cardiac Purkinje Fiber Network: Linking Architecture and Function

Journal of Cardiovascular Development and Disease, 2021
The rapid propagation of electrical activity through the ventricular conduction system (VCS) controls spatiotemporal contraction of the ventricles. Cardiac conduction defects or arrhythmias in humans are often associated with mutations in key cardiac ...
