%e report muon spin rotation measurements on the antiferromagnetic heavy-fermion superconductor UPd2A13 in the superconductin state. The Lpndon penetration depth is found to be approximately isotropic, A~(0) = 4800~500 and A~~(0) = 4500~500 A. The~+ Knight shift behavior below T, indicates that local moment magnetism and superconductivity are carried by different electron substrates of 5f character, one of which involves the heavy qnasiparticles. For the latter a nearly isotropic magnetic susceptibility g = 1.7 & 10 emu/mole can be estimated. PACS numbers: 74.70.Tx, 75.30.Mb, 76.75.+i The large variations in the ground state properties

The treatment of vertical bone defects caused by severe periodontal disease requires the regeneration of periodontal tissue. Although various bone substitutes have been clinically applied to vertical bone defect correction, the evaluation of these materials in periodontal tissue remains incomplete. The purpose of this study was to examine the bone regeneration abilities of various bone substitutes including Cytrans, Cerasorb, Neobone and Bio-Oss in a 3-wall bone defect animal model. All of these bone substitutes showed a similar healing ability to periodontal ligament and cementum. However, Cytrans showed the fastest bone healing ability compared with the other materials at 4 weeks post-transplantation. In addition, the recruitment of osteoclasts and endothelial cells was observed in Cytrans grafts at 4 weeks, but only detected at 8 weeks in the other materials. These results suggest that Cytrans promotes faster bone healing by inducing bone remodeling and angiogenesis.
