Semaphorins comprise a large family of phylogenetically conserved secreted and transmembrane glycoproteins, many of which have been implicated in repulsive axon guidance events. The transmembrane semaphorin Sema-1a in Drosophila is expressed on motor axons and is required for the generation of neuromuscular connectivity. Sema-1a can function as an axonal(More)
BACKGROUND Henoch-Schönlein purpura (HSP) is a common IgA-mediated vasculitis in children. The antigenic target for IgA is to be determined. OBJECTIVE To test whether β2-glycoprotein I (β2GPI) is an antigenic target for IgA in childhood HSP, and to evaluate the clinical implications and pathogenic role of such IgA autoantibodies. METHODS The reactivity(More)
Five different crystal forms of recombinant chicken-liver glutathione S-transferase CL 3-3 have been obtained by the vapor-diffusion method. The form A crystals are monoclinic C2, a = 125.56, b = 85.81, c = 52.71 A and beta = 114.64 degrees, and diffract to 4 A resolution. The form B crystals are monoclinic P2(1), a = 105.13, b = 118.54, c = 62.62 A and(More)
The purpose of this study was to estimate the prevalence of mental retardation (MR) in Korea. The study population comprised 1,757 third-grade elementary school children residing in a single school district in Suwon, Korea. We conducted the total population survey for 1,537 children who attended one of 5 schools in the district. For the remaining 220(More)
