    Repolarization is the return of the ions to their previous resting state, which corresponds with relaxation of the myocardial muscle

    Isn't systole contraction not relaxation? Diastole is relaxation.

    Gene Therapy is where you try and alter someones DNA in order to bring about some benefit to the individual, whether that be alleviating symptoms of say Cystic Fibrosis or upping your EPO levels as seen in the pre-release article.

    Usually done by getting a virus, altering its DNA/RNA and using it to 'infect' the human cell and so alter the human cells DNA inserting the desired gene.
