Semaphorins, originally identified as axon guidance facto s in the nervous system, play integral roles in organogenesis. Here, we demonstrate a critical involvement of Sema6D in cardiac morphogenesis. Ectopic expression of Sema6D o RNA interference against Sema6D induces expansion or narrowing of the ventricular chamber, respectively, during chick embryonic(More)
Cardiac chamber formation involves dynamic changes in myocardial organization, including trabeculation and expansion of the compact layer. The positional cues that regulate myocardial patterning, however, remain unclear. Through ligation of the Plexin-A1 receptor, the transmembrane-type semaphorin Sema6D regulates endocardial cell migration. Here, we(More)
Originally identified as axon guidance molecules, semaphorins are now known to be widely expressed mediators that play significant roles in immune responses and organ morphogenesis. However, not much is known about the signaling pathways via which they exert their organ-specific effects. Here we demonstrate that Sema4A, previously identified as an activator(More)
To evaluate real-world outcomes of PCI in unselected individuals using sirolimus-eluting (SESs) or paclitaxel-eluting stents (PESs) in a single-center randomized trial. Eight hundred consecutive patients (919 lesions) with coronary artery disease were randomized to receive SES or PES implantation. In-hospital, mid-term, and 1-year clinical and(More)
BACKGROUND  Mechanical reperfusion has proven to be an unquestionably superior treatment strategy over that of thrombolytic therapy in patients with acute coronary syndrome (ACS). Excimer laser coronary angioplasty (ELCA) is a unique revascularization device that has a lytic effect on thrombus, in addition to its debulking effect on the atherosclerotic(More)
Atmospheric Data Collection Lidar (ADCL) of the Center for Environmental Remote Sensing (CEReS), Chiba University, is a multi-wavelength lidar system designed for measuring tropospheric aerosols and clouds with ancillary data from ground-based aerosol measurement instruments. In this paper, we report on the concept of aerosol and cloud retrieval based on(More)
OBJECTIVES The aim of this study was to compare the ability of conventional versus computed tomography angiography (CTA) to predict procedural success and 30-min wire crossing rates in percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) lesions. BACKGROUND Coronary CTA can be used to assess the morphology of CTO lesions. METHODS(More)
