The effects of 2,5-di-tert-butylhydroquinone (TBQ) on cardiac muscle contractility were investigated using cardiac preparations from the right ventricle of the rat. In saponin-skinned preparations, TBQ (50 and 100 microM) did not significantly affect the maximal isometric Ca2+-activated force or the

Cellular Ca(2+) waves are understood as reaction-diffusion systems sustained by Ca(2+)-induced Ca(2+) release (CICR) from Ca(2+) stores. Given the recently discovered sensitization of Ca(2+) release channels (ryanodine receptors; RyRs) of the sarcoplasmic reticulum (SR) by luminal SR Ca(2+), waves could
