Aim
Atrial fibrillation is the most common persistent cardiac arrhythmia, and it is not well controlled by present drugs. Because some resin acids open voltage‐gated potassium channels and reduce neuronal excitability, we explored the effects of the resin acid isopimaric acid (IPA) on action potentials and ion currents in cardiomyocytes.
Methods
Spontaneously beating mouse atrial HL‐1 cells were...
We demonstrate for the first time 85nm gate length enhancement and depletion mode InSb quantum well transistors with unity gain cutoff frequency, fT, of 305 GHz and 256 GHz, respectively, at 0.5V VDS, suitable for high speed, very low power logic applications. The InSb transistors demonstrate 50% higher unity gain cutoff frequency, fT, than silicon NMOS transistors while consuming 10 times less active...
Abstract. An understanding of very complex natural systems can often only be achieved through detailed studies of systems with a reduced complexity. Thus, de novo design of proteins allows the study of fundamental forces determining protein folding and stability, as well as protein-protein interactions, by analyses of protein models of structural motifs. In addition, de novo design may lead to new...
