Web12. apr 2024 · For the simulation of redox potentials, we focused on the calculation of the reduction potentials. The reduction potential ( E0) can be calculated by the following equation: E0 = −Δ G0 ( t )/ (− nF ), where Δ G0 ( t) is Gibbs free energy change, n is the number of electrons participating in the reaction, and F is Faraday constant. Web23. dec 2011 · We have shown that, during reoxygenation, highly localized, transient waves of elevated [Ca 2+] c diffuse across the myocardium at an average speed of 3.3 µm/s. In 44% of cases, [Ca 2+] c waves of a sufficient intensity preceded mPTP opening, particularly during the first 20 min of reoxygenation.
