    Notes: A new measuring system using an optical fiber and a position sensing photodetector was developed to measure a three-dimensional distribution of a magnetic force. A steel ball attached to a cantilever made of an optical fiber generated force in a magnetic field. The displacement of the ball due to the force was detected by a position-sensing photodetector with the capability of detecting two-directional coordinates of the position. By scanning the sensing system in a magnetic field, we obtained distributions of two-directional component of the magnetic force vector. The component represents the gradient of a squared magnetic field. The usefulness of the system for measuring the magnetic field distribution in a narrow clearance and for evaluating superconducting machine components such as magnetic bearings was verified experimentally.

    Measurement of superconducting characteristics of high Tc materials by the magnetic force sensing system (1993)

    Notes: A magnetic force sensing system using a highly sensitive force sensor was developed to measure the two-dimensional distribution of superconducting properties of high Tc materials. A probing tip made of a small piece of magnetized material was mounted on a cantilever scanned over superconducting surfaces. Magnetic properties of the superconductor generated force on the tip and the force was measured by an optical displacement sensor. Two kinds of YBCO superconductor were examined by the measuring system in order to compare their repulsive force and shielding characteristics. Two-dimensional distribution of repulsive force due to the Meissner effect of YBCO, which was fabricated by the melt powder melt growth (MPMG) process, showed evident nonuniformity which is attributed to the nonuniformity of chemical composition of the material. Although the MPMG materials are capable to be used as a magnetic shield, they have much larger residual flux than the materials fabricated by the solid phase reaction process.

    Successful Treatment of Rapidly Progressive Lupus Nephritis Associated with Anti-MPO Antibodies by Intravenous Immunoglobulins (1999)

    Notes: Abstract: We report a case of systemic lupus erythematosus (SLE) associated with crescentic glomerulonephritis and myeloperoxidase-specific anti-neutrophil cytoplasmic antibodies (MPO-ANCA). A 34-year-old Japanese female patient diagnosed with SLE developed rapidly progressive renal failure and nephrotic syndrome. Haemodialysis was required to restore renal function. Methylprednisolone pulse therapy followed by plasmapheresis did not suppress the progression of renal failure, so she was treated with high-dose intravenous immunoglobulin (IV-IG) therapy, which was well tolerated and effectively prevented renal failure. A renal biopsy showed diffuse proliferative lupus nephritis (WHO classification IVc) with predominant crescent formation and scant subendothelial immune deposits. These findings indicate that, in addition to lupus nephritis, which usually results from the deposition of circulating or locally formed immune complexes, MPO-ANCA may be involved in the pathogenesis of crescentic glomerulonephritis. Furthermore, we propose that IV-IG is an effective therapy for MPO-ANCA-related renal crisis in lupus nephritis.

    Plant regeneration from protoplasts of Iris hollandica Hort. (1999)

    Notes: Abstract The effects of glucose concentrations, different sugars and combinations of 2,4-D and kinetin on cell division and colony formation were examined in cultures of protoplasts isolated enzymatically from suspension cultures of Iris hollandica N6 medium supplemented with 1 mg/l 2,4-D, 1 mg/l kinetin, 200 mg/l casein hydrolysate, 250 mg/l proline, 0.3– 0.5 M glucose and 20 g/l agarose was suitable for cell division and colony formation. When colonies formed were transferred to hormone-free MS medium, many shoots were induced. In addition, when induced shoots were transferred to MS medium with 1 mg/l NAA, root induction was observed. A plant regeneration system from protoplasts of I. hollandica was thus established.
