Solution‐Processed Two‐Dimensional Indium Oxide on Sodium‐Embedded Alumina for Reconfigurable Optoelectronic Synaptic Transistors

Advanced Functional Materials, EarlyView.
Wafer‐scale two‐dimensioanl In2Se3 oxidized into InOx on sodium‐embedded beta‐alumina enables multifunctional reconfigurable electronics. Sodium ions accumulate within distinct spatial distribution under drain‐controlle and gate‐controlled operation. Drain‐control operation gives controllability of ultraviolet‐driven optoelectronic synaptic conductance

Inhibition of voltage-gated sodium channels by sumatriptan bioisosteres

Frontiers in Pharmacology, 2015
Voltage-gated sodium channels are known to play a pivotal role in perception and transmission of pain sensations. Gain-of-function mutations in the genes encoding the peripheral neuronal sodium channels, hNav1.7-1.9, cause human painful diseases.

Gain of function mutants: Ion channels and G protein-coupled receptors [PDF]

, 2000
Many ion channels and receptors display striking phenotypes for gain-of-function mutations but milder phenotypes for null mutations. Gain of molecular function can have several mechanistic bases: selectivity changes, gating changes including constitutive

An Edible H2O2 Biosensor for Gastrointestinal Metabolites and Peroxidase Enzyme Quantification

Advanced Healthcare Materials, EarlyView.
We present an edible biosensor for gastric fluid analysis that integrates a caffeic acid–horseradish peroxidase redox system into an edible electrolyte‐gated transistor. The device enables rapid, low‐volume detection of H2O2 and, with minimal modification, metabolites and enzyme activity in simulated gastrointestinal conditions.

Na(V)1.5 sodium channel window currents contribute to spontaneous firing in olfactory sensory neurons [PDF]

, 2014
Olfactory sensory neurons (OSNs) fire spontaneously as well as in response to odor; both forms of firing are physiologically important. We studied voltage-gated Na+ channels in OSNs to assess their role in spontaneous activity.

Coaxially Electrospun Myocardial dECM‐ Based Nanofibrous Scaffolds Demonstrate Enhanced Cardiomyocyte Biocompatibility

Advanced Healthcare Materials, EarlyView.
Our coaxial electrospinning system is capable of incorporating decellularized myocardial extracellular matrix in a core‐sheath configuration, creating nanofibrous scaffolds. These scaffolds, in turn, support the maintenance of functional cardiomyocytes adhered to the surface of these bioactive scaffolds.

Breaking the pain barrier: how suzetrigine and selective sodium channel blockers are reshaping the future of opioid-free analgesia

Quality in Sport
Introduction: Pain is a complex clinical challenge, with opioids traditionally used despite the risks of dependency and overdose. The need for safer alternatives has led to growing interest in voltage-gated sodium channels, particularly NaV1.7, NaV1.8 ...

In vivo spatiotemporal control of voltage-gated ion channels by using photoactivatable peptidic toxins

Nature Communications, 2022
Photoactivable toxins targeting ion channels have great potential to control cell activity. Here the authors report HwTxIV-Nvoc, a UV light-cleavable and photoactivatable peptide that targets voltage-gated sodium channels; they validate this in cells ...
