Simultaneous Comparison of Many Triphasic Defibrillation Waveforms

Biphasic defibrillation waveforms are now accepted as being more effective at terminating ventricular fibrillation (VF) than monophasic waveforms. If two phases are better than one, this naturally leads to the hypothesis that additional phases improve efficacy. This study tests the hypothesis by adding one additional phase. We examined the efficacy of 18 different triphasic waveforms simultaneously

zpl, a new gene in drosophila required for neurogenesis

zpl (zip-like) gene mutant embryos showed the cuticular defect with alternative denticle rows and a hole from head to abdomen. zpl mutants also caused the overgrowth of neural cells and axons both in CNS and PNS as well as the wrong pathway of neural fasciculation and the disappearance of hypophysis, as shown by whole mount embryos stained with antibody against HRP and MAb-22C10. Genetic analysis has provided evidence that zpl, located in the right arm of the second chromosome (between 75 and 102 genetic map units), is a new gene closely related to the zip gene
