Screening For The Genetic Defect

Genetic screening in countries such as the United States is performed only as a research procedure. In Europe, genetic screening has been accepted in certain countries as a routine medical procedure. It is of note that only one gene, the cardiac sodium channel, has been identified and thus may only account for a small percentage of inherited Brugada syndrome. A second locus has been identified on chromosome 3 but the gene has not been isolated. We recommend sequencing the whole of the cDNA for cardiac sodium channel. This is necessary as over 60 mutations have already been identified in the sodium channel to be responsible for Brugada syndrome. It is recommended that all of the exons be amplified from genomic DNA. The sequencing primers are available online in GenBank.

Getting Started With Dumbbells

The use of dumbbells gives you a much more comprehensive strengthening effect because the workout engages your stabilizer muscles, in addition to the muscle you may be pin-pointing. Without all of the belts and artificial stabilizers of a machine, you also engage your core muscles, which are your body's natural stabilizers.
