We report the discovery of pressure-induced superconductivity in an antiferromagnet CeIrSi 3 , which lacks inversion symmetry tetragonal crystal structure. The Néel temperature T N = 5.0 K at ambient pressure decreases monotonically with increasing pressure, and becomes zero about 2.5 GPa. Superconductivity appears a wide region from 1.8 GPa to 3.5 GPa, relatively large superconduting transition sc 1.6 upper critical field H c2 (0) 11.1 indicating heavy-fermion superconductivity.

Background Nephrotic syndrome is the most common cause of chronic glomerular disease in children. Most these patients develop steroid-sensitive nephrotic (SSNS), but loci conferring susceptibility to childhood SSNS are mainly unknown. Methods We conducted a genome-wide association study (GWAS) Japanese population; 224 with and 419 adult healthy controls were genotyped using Affymetrix Japonica Array discovery stage. Imputation for six HLA genes ( HLA-A , -C, -B -DRB1 -DQB1 -DPB1 ) was on...

Single crystals of LaIrSi 3 and CeIrSi were grown by the Czochralski pulling method in a tetra-arc furnace magnetic superconducting properties, together with superconductivity CeIr 1- x Co Si , clarified measuring electrical resistivity, specific heat, susceptibility, magnetization de Haas–van Alphen (dHvA) effect. From results dHvA experiment for Fermi surface is found to split into two surfaces due spin–orbit interaction arising from non-centrosymmetric crystal structure, which are...

We studied the pressure-induced superconductor CeIrSi$_3$ with non-centrosymmetric tetragonal structure under high pressure. The electrical resistivity and ac heat capacity were measured in same run for sample. critical pressure was determined to be $P_{\rm c}$ = 2.25 GPa, where antiferromagnetic state disappears. $C_{\rm ac}$ shows both superconducting transitions at pressures close c}$. On other hand, region is extended of up about 3.5 maximum transition temperature $T_{\rm sc}$ 1.6 K...

C3 glomerulonephritis (C3GN) is a recently described disease that related to membranoproliferative (MPGN). We retrospectively compared the frequencies, clinical characteristics, treatment modalities, and outcomes of C3GN MPGN in cohort Japanese children.Children who were pathologically diagnosed with (type I or III) our hospital divided into two groups based on immunofluorescence imaging renal biopsies: children induced by classical complement pathway activation (classical MPGN) C3GN.Of 14...

CO2 responsiveness of the cerebral circulation has been measured in baboons before, during, and after halothane-induced hypotension. At a systolic blood pressure (BP) 60 mmHg, C02 was abolished, but maintained at higher levels BP. After hypotension, returned to control values. Autoregulation BP increases induced by intravenous noradrenaline impaired when perfusion during hypotensive period had below 30-40 mmHg. It is concluded that hypotension commonly employed clinically, may be absent. The...

We carried out the de Haas–van Alphen (dHvA) experiment of an antiferromagnet CeCoGe 3 and its reference compound LaCoGe without inversion symmetry in tetragonal crystal structure. The detected dHvA branches are similar between two compounds. All well explained by results energy band calculations. There exist three types compenstated Fermi surfaces. Each surface is found to consist surfaces, which characteristic structure symmetry. main branch possess relatively large cyclotron mass m c *...
