Bacterial DNA induces myocardial inflammation and reduces cardiomyocyte contractility: role of toll-like receptor 9.

abstract：OBJECTIVE:Jervell and Lange-Nielsen syndrome (JLNS) is a recessively inherited long QT syndrome (LQTS) characterised by profound sensorineural deafness and predisposition to syncope and sudden cardiac death. Mutation analysis has established the presence of mutations in affected individuals in the genes KCNQ1 and KCNE1...

abstract：:An oscillatory current (Ios) can be recorded after depolarising clamps of a given amplitude and duration. To determine whether Ios depends on other currents activated during the clamp, the Ios was investigated in the absence and in the presence of 4-aminopyridine (4-AP) and cesium (Cs). The following results were obta...
