 Context examples 

Furthermore, this agent dissipates action potential on the bacterial mitochondrial membrane by inducing permeability, thereby leading to respiratory inhibition and subsequent cell death.

(Gentian Violet, NCI Thesaurus)

This results in prolongation of atrial and ventricular action potential duration and refractory periods.

(Ibutilide Fumarate, NCI Thesaurus)

This interaction is involved in the stimulation of Gs protein-dependent signaling, which regulates potassium ion flux, neuronal action potentials, voltage-dependent calcium channel activity and neurotransmitter release.

(Gamma-Amino Butyric Acid Type B Receptor Binding, NCI Thesaurus)

This reversibly stabilizes the membrane and inhibits depolarization, leading to the failure of a propagated action potential and subsequent conduction blockade.

(Dyclonine, NCI Thesaurus)

This antiarrhythmic agent prolongs cardiac action potential duration and effective refractory period due to delayed repolarization without affecting conduction velocity.

(Dofetilide, NCI Thesaurus)

The agent decreases the flow of sodium ions into myocardial tissue, especially on the Purkinje network, during phase 0 of the action potential, thereby decreasing depolarization, automaticity and excitability.

(Lidocaine Hydrochloride, NCI Thesaurus)

It causes direct inhibition of action potentials in myometrial muscle cells.

(Magnesium sulfate, NLM, Medical Subject Headings)

Neuron Conduction Inhibition involves interference with, or restraint of, activities that propagate the transfer of the electrochemical action potential process along nerve fibers away from the cell body.

(Neuron Conduction Inhibition, NCI Thesaurus)

This leads to a reduction in posttetanic potentiation at synapses, an inhibition of repetitive firing of action potentials and ultimately inhibits the spread of seizure activity.

(Phenytoin sodium, NCI Thesaurus)

Neuron Conduction Induction involves initiation of activities that propagate the transfer of the electrochemical action potential process along nerve fibers away from the cell body.

(Neuron Conduction Induction, NCI Thesaurus)
