KCNJ4 variants disrupt inward‐rectifier potassium channel function and cause refractory epilepsy

Epilepsia, EarlyView.
Abstract Objective Epilepsy is a common neurological disorder with a strong genetic basis, most frequently arising from ion channel dysfunction. Although multiple inwardly rectifying potassium (Kir) channels have been implicated in epileptogenesis, the contribution of KCNJ4, which encodes the Kir2.3 channel, has not previously been established in human

Neonatal developmental and epileptic encephalopathy with movement disorder and arthrogryposis: A shared phenotype across brain‐expressed sodium channelopathies

Epilepsia, EarlyView.
Abstract Objective Neonatal developmental and epileptic encephalopathy with movement disorder and arthrogryposis (NDEEMA) represents the most severe end of the gain‐of‐function (GOF) SCN1A disorder spectrum. Sporadic cases of congenital arthrogryposis have also been reported in individuals with SCN2A‐, SCN3A‐, and SCN8A‐related developmental and ...

Robust conversion of singlet spin order in coupled spin-1/2 pairs by adiabatically switched RF-fields

, 2016
We propose a robust and highly efficient NMR technique to create singlet spin order from longitudinal spin magnetization in coupled spin-1/2 pairs and to perform backward conversion (singlet order)$\to$magnetization.

Cardiac remodeling and arrhythmia in a mouse model of Depdc5 haploinsufficiency

Epilepsia, EarlyView.
Abstract Objective Some ion channel genes linked to developmental and epileptic encephalopathy (DEE) are also linked to cardiac arrhythmia, leading to the hypothesis that predisposition to cardiac arrhythmias may contribute to the complex disease presentation of DEE and possibly to the mechanism of sudden unexpected death in epilepsy.

Membrane potential hyperpolarization: a critical factor in acrosomal exocytosis and fertilization in sperm within the female reproductive tract

Frontiers in Cell and Developmental Biology
Hyperpolarization of the membrane potential (Em), a phenomenon regulated by SLO3 channels, stands as a central feature in sperm capacitation—a crucial process conferring upon sperm the ability to fertilize the oocyte.

Zero field optical magnetic resonance study of phosphorus donors in 28-silicon

, 2018
Donor spins in silicon are some of the most promising qubits for upcoming solid-state quantum technologies. The nuclear spins of phosphorus donors in enriched silicon have among the longest coherence times of any solid-state system as well as ...

An n‐of‐1 gene‐directed drug repurposing trial for an ultrarare genetic condition

Epilepsia, EarlyView.
Abstract Objective Gain‐of‐function (GoF) variants in the KCNC1 potassium channel subunit gene (Kv3.1) cause motor/cognitive delays and hypotonia and have been associated with seizures. Fluoxetine has inhibitory effects on Kv3.1. However, open‐label nonrandomized administration is insufficient to guide clinical decision‐making in ultrarare conditions ...

Para‐hydrogen enrichment and hyperpolarization

Concepts in Magnetic Resonance Part A, 2006
AbstractThis article begins with general considerations about enrichment of hydrogen gas into its para isomer (corresponding to nuclear spins in the singlet state); this is a necessary condition to obtain hyperpolarization from transfer of the relevant population excess.

WONOEP XVII appraisal: The role of the extracellular matrix in epilepsy

Epilepsia, EarlyView.
Abstract The extracellular matrix (ECM) is composed of proteoglycans and glycoproteins that regulate the external environment surrounding neurons, glia, and the vascular system. The ECM is vital for maintaining the structure and function of the brain and also acts as a reservoir for various signaling molecules and neurotransmitters, modulating synaptic

Cardiovascular Applications of Hyperpolarized MRI [PDF]

Current Cardiovascular Imaging Reports, 2011
Many applications of MRI are limited by an inherently low sensitivity. Previous attempts to overcome this insensitivity have focused on the use of MRI systems with stronger magnetic fields. However, the gains that can be achieved in this way are relatively small and increasing the magnetic field invariably leads to greater technical challenges.
