When using traditional heating under reflux conditions many transition metal-catalyzed C-C and C-X bond forming reactions typically need hours or days to reach completion. Fast and reliable microwave protocols are therefore very much needed for speeding up transformations in the field of homogeneous catalysis, taking into account the advantages of microwave heating – rapid transfer of energy and inverted temperature gradients, by increasing the lifetime of the catalyst, i.e. eliminating the wall effects seen in convetional heating methods.
These results support the use of hSC-CM and MEA technology for preclinical assessment of proarrhythmic risk within the proposed CiPA paradigm, and, more generally, demonstrate that automation of the CM-MEA assay can achieve high reliability and throughput for cardiac risk assessment in vitro.READ MORE
