The aim of this study was to compare the efficacy and retention rates of three biologics (abatacept, tocilizumab, and etanercept) after switching from first-course anti-TNF monoclonal antibody therapy. We performed a retrospective multicenter study of 89 patients who underwent second-course biologic therapy for 52 weeks after switching from first-course(More)
SUMMARY An emitter coupled logic (ECL) compatible low-power GaAs 8 : 1 multiplexer (MUX) and 1 : 8 demultiplexer (DEMUX) for 10-Gb/s optical communication systems has been developed. In order to decrease the power consumption and to maximize the timing margin, we estimated the power consumption for direct-coupled FET logic (DCFL) and source-coupled FET(More)
