    Notes: Summary Experimental allergic myositis (EAM) was produced in SJL/J mice by inoculation with the myosin B fraction of the rabbit skeletal muscle, and the pathological changes were quantified. The myosin B fraction contains actin, myosin, tropomyosin and many other proteins, and has been known to induce severe EAM in guinea pigs. In the present model, macrophages and CD4+ lymphocytes predominated among the infiltrating cells. On the surface of muscle fibers and in the regions of cell infiltration deposition of the immunoglobulin G (IgG) and complement factor 3 was observed. EAM was transferred to normal mice by injecting the serum IgG of EAM. Depleting the recipients of complement before the transfer resulted in less-severe pathological changes. Morphologically, the EAM IgG showed an affinity for the nuclei, myofilaments, sarcolemma and blood vessels of mouse skeletal muscle. Biochemically EAM IgG contained antibodies against myosin, actin, troponin, M protein and other muscle proteins. These results indicated that IgG and complement play important roles in this model.

    Notes: Summary The occurrence is reported of acute myositis in a man with meningoencephalitis due to toxoplasmosis. The ultrastructure and immunohistochemistry of a muscle biopsy of the patient were investigated. Toxoplasma organisms were not found in the muscle biopsy. The perivascular inflammatory cells in the muscle were mainly CD4+ T cells and the inflammatory cells in and around the muscle fibres were chiefly macrophages. Expression of major histocompatibility complex class I and II antigens was observed in the infiltrating cells and endothelial cells of the blood vessels. A small proportion of the infiltrating cells expressed interferon-γ. A possible role of the immune mechanism in the evolution of myositis is discussed.

    Epitaxial relations between in situ superconducting YBa2Cu3O7−x thin films and BaTiO3/MgAl2O4/Si substrates (1990)
    [S.l.] : American Institute of Physics (AIP)

    Notes: In situ superconducting YBa2Cu3O7−x films with Tc0 up to 87 K and Jc, 77 K up to 6×104 A/cm2 were prepared on Si substrates with MgAl2O4 and BaTiO3 double-buffer layers. The epitaxial relations between various layers were established by transmission electron microscopy. The MgAl2O4 layer is heavily faulted. The subsequent BaTiO3 layer stops most of the faults, provides a template for the YBa2Cu3O7−x growth, and partially screens off the stress due to different thermal expansion coefficients. The microstructure of the YBa2Cu3O7−x layer is very similar to that of the films deposited directly on SrTiO3, exhibiting a homogeneous heavily faulted single-crystal-like structure free from secondary phases and grain boundaries. The slight degradation of the transport properties is attributed to residual thermal stress.

    Notes: Time-resolved photoconductivity measurements with subnanosecond time resolution are applied to study the electric field profile in amorphous silicon solar cells in the range from 0.3 V forward to 0.8 V reverse bias. The method is used for a comparison of state-of-the art devices with different junction design. Optical and electrical contributions to the device performance are discussed and the limitations in improving the performance by use of a-SiC:H window layers are pointed out.

    Space-charge distribution and trapping kinetics in amorphous silicon solar cells (1992)

    Notes: Using electron time-of-flight experiments we have determined the electric field profile and the electron transport efficiency in amorphous silicon solar cells. In optimized devices we find a correlation between the space-charge distribution and the trapping behavior at the p-i junction, indicating that charged defects in the space-charge region determine both, the electric field distribution and the trapping kinetics. From their capture cross section the charged states are identified as positively charged dangling bonds.

    New compositional and optical data for antimonian and bismuthian varieties of hemusite from Japan (1991)

    Description / Table of Contents: Zusammenfassung Neue chemische und optische Daten für antimon- und bismuthführende Hemusite auf epithermalen Au-Ag-Cu Lagerstätten in Japan werden vorgelegt. Die empirische Formel für die antimon-führende Varietät aus der Iriki-Mine ist: (Cu5.83Fe0.14Ag0.01)Σ5.98Mo1.03(Sn0.54Sb0.41Te0.03Bi0.02)Σ1.00 (S7.85Se0.15)Σ8.00, und die der Sb-Bi Varietät aus der Kawazu Mine ist: (Cu5.84Fe0.14Ag0.01)Σ5.99M01.03(Sn0.82Sb0.11Bi0.l0Te0.04)Σ1.07 (S7.80Se0.12)Σ7.92. Die theoretische Formel von Hemusit ist Cu+ 4Cu2+ 2Mo4+Sn4+S8, während die wahrscheinlichere Formel für den Hemusit von Iriki Cu+ 4Cu2+ 1.5Mo4+Sn4+ 0.5Sb5+ 0.5S8, mit Sb5+ an der Stelle von Sn4+, das(SbS4)3− Tetraeder bildet, wie zu erwarten ist, unter der Voraussetzung, da♭ das Metall zu Schwefelverhältnis 1 und die Struktur sphaleritähnlich ist. Bi3+ kann jedoch nicht in dieser Weise untergebracht werden, und das führt zu einem Mangel an (S + Se) für den Hemusit von Kawazu. Die Reflektions-Spektren beider Minerale werden mit denen des Wolfram-Equivalents von Hemusit (Kiddcreekit) verglichen. Die Beziehung zwischen Hemusitsensu stricto und diesen jetzt beschriebenen Varietäten wird auf der Basis einfacher und gekoppelter chemischer Substitution diskutiert. Auf dieser Basis werden Schlüsse auf die Valenz von Sb, Bi Mo und Cu in der Hemusit-Struktur gezogen.
    Notes: Summary New compositional and optical data are reported for antimonian and antimonianbismuthian varieties of hemusite from epithermal Au-Ag-Cu deposits in Japan. The empirical formula for the antimonian variety, from the Iriki mine is: (Cu5.83Fe0.14Ag0.01)Σ5.98Mo1.03(Sn0.54Sb0.41Te0.03Bi0.02)Σ1.00(S7.85Se0.15)Σ8.00, and that of the Sb-Bi variety from the Kawazu mine is: (Cu5.84Fe0.14Ag0.01)Σ5.99Mo1.03(Sn0.82Sb0.11Bi0.l0Te0.04)Σ1.07(S7.80Se0.12)Σ7.92. The theoretical formula of hemusite is Cu+ 4Cu2+ 2MO4+Sn4+S8, whilst the most probable formula of the Iriki hemusite is Cu+ 4.5CU2+ 1.5Mo4+Sn4+ 0.5Sb5+ 0.5S8, with Sb5+ substituting for Sn4+ and forming (SbS4)3− tetrahedra as might be expected, given that the metal to sulphur ratio is 1, and given the sphalerite-like structure of the mineral. However Bi3+ cannot be so accommodated, resulting in a deficiency in (S + Se) for Kawazu hemusite. Reflectance spectra for both are compared with those of the tungsten analogue (compositional) of hemusite, kiddcreekite. The relationship between hemusitesensu stricto and these newly reported varieties is discussed in terms of simple and coupled chemical substitutions, and inferences are drawn on the valency of Sb, Bi, Mo and Cu in the hemusite structure.

    Notes: Summary The density of 5-HT1A binding using3H-8-hydroxy-2-(di-n-propylamino) tetralin (8-OH-DPAT) as binding ligand, was studied in human frontal cortex of suicide victims and normal controls who died due to medical disease or accidentally. There was no difference in the maximum number of binding site (Bmax) or Kd (an inverse measure of affinity) of 5-HT1A receptor binding sites between normal controls and the entire group of suicide victims. However, nonviolent suicides had significantly higher Bmax (22—25%) compared to both controls and violent suicides. A negative correlation between age and Bmax of 5-HT1A binding sites was found in male controls but not in female controls or suicide victims. This relationship was less apparent among the male controls over age 60.

    Notes: Abstract A case of acute myopathy was observed in the course of treatment of respiratory failure with mechanical ventilation combined with prolonged neuromuscular blockade and administration of corticosteroids. A muscle biopsy revealed degeneration of muscle fibres. Electron microscopy showed loss of thick filaments as well as nemaline rods, vacuoles and cytoplasmic bodies. The mitochondria were increased in number, many harbouring paracrystalline inclusions, which were hitherto unknown in this condition.
