Previous studies of reentrant arrhythmias in the heart have been performed in computer models and tissue experiments. We hypothesized that confluent monolayers of cardiac cells can provide a simple, controlled, and reproducible experimental model of reentry. Neonatal rat ventricular cells were cultured on 22-mm-diameter coverslips and stained with the voltage-sensitive dye RH-237. Recordings of...

Catheter ablation of AF effective treatment option for symptomatic patients. The long-term efficacy however not very well studied nor health consumption before after an atrial fibrillation.

This study describes a multiplex PCR assay developed for the detection of Staphylococcus aureus enterotoxin types: SEA, SEB, SEC, SED, and SEE presented in the literature as classical. The method was then used to analyse the presence of genes encoding these enterotoxins in .S aureus strains isolated from raw milk. A total of 237 raw milk samples were used in the study and 77 (32.5%) of them wer...
