Effects of the antiarrhythmic and antimyotonic drug mexiletine were studied on two sodium channel mutants causing paramyotonia congenita (R1448H) and an overlap paramyotonic and hyperkalemic paralytic syndrome (M1360V). Channels were expressed in human embryonic kidney cells and studied electrophysiologically, using the whole-cell patch-clamp technique.(More)
BACKGROUND Animal experiments revealed that succinylcholine produced masseter muscle rigidity and activated myotonic discharges despite neuromuscular blockade with a nondepolarizing blocker. These results suggest that either succinylcholine or its metabolites might interfere directly with voltage-operated ion channels of the sarcolemma. The aim of this(More)
1 The effects of 4-Chloro-m-Cresol (4-CmC) were examined on heterologously expressed wild type (WT), Paramyotonia Congenita (R1448H) and Hyperkalemic Periodic Paralysis (M1360V) mutant alpha-subunits of human muscle sodium channels. 2 Block of rested sodium channels caused by 4-CmC was concentration-dependent with an ECR50 of 0.40 mM in WT, 0.45 mM in(More)

An endogenous factor that is able to reduce the fast transient sodium current of excitable cells has been reported to exist in the cerebrospinal fluid (CSF) of multiple sclerosis (MS) patients. This was confirmed with nine clinically definite MS patients in the acute relapse. In order to purify and chemically identify the factor, microconcentration and gel(More)
World Health Organization (WHO) and their partners have agreed to update the data on the occurrence of resistance of influenza A/H1N1 viruses to oseltamivir appearing on the ECDC and EISS websites on a weekly basis (every Thursday afternoon). Data on the ECDC website are for European Union (EU) and European Free Trade Association (EFTA) countries. The WHO(More)
