Temperature-dependent model of human cardiac sodium channel
Cardiac sodium channels are integral membrane proteins whose structure is not known at atomic level yet and their molecular kinetics is still being studied through mathematical modeling. This study has focused on adapting an existing model of cardiac Na channel to analyze molecular kinetics of channels at 9-37°C. Irvine et al developed a Markov model for Na channel using Neuronal Network Model ...

متن کاملEvidence for developmental changes in sodium channel inactivation gating and sodium channel block by phenytoin in rat cardiac myocytes.
The voltage-dependent properties of the voltage-activated sodium channel were studied in neonatal (1-2-day-old) and adult rat ventricular cardiac myocytes using the whole-cell variation of the patch-clamp technique (16 degrees C, [Na]i = 15 mM, [Na]o = 25 mM). The voltage dependence of the sodium conductance-membrane potential relation was similar in both neonatal and adult myocytes except for ...
متن کاملCalixmexitil: Calixarene-based Cluster of Mexiletine with Amplified Anti-myotonic Activity as A Novel Use-dependent Sodium Channel Blocker
Mexiletine as the first choice drug in myotonia treatment is a chiral sodium channel blocker clinically used in its racemic form. The phenolic structure of this drug, prompted us to design its novel calix[4]arene-based cluster in a chalice-shaped structure. Therefore, the present study reports the synthesis and in-vitro anti-myotonic activity of the chalice-shaped cluster of mexiletine...
