    Antibodies to brain tissue in sera of schizophrenic patients (1993)
    Springer
    European archives of psychiatry and clinical neuroscience 242 (1993), S. 314-317 
    Details
    ISSN: 1433-8491
    Keywords: Schizophrenia ; Pathogenesis ; Autoimmune disease

    Topics: Medicine
    Notes: Summary The sera of 30 patients suffering from schizophrenia (DSM III) and 30 neurological controls were tested for antibrain antibodies in a blind indirect immunofluorescence assay. We found IgG- and IgM-binding in the sera of 22 patients, but only 4 out of the 30 age- and sex-matched controls. The binding was mainly directed to neurons from the frontal cortex and septal area, areas, which are regarded as important in the development of schizophrenic illness. These preliminary data are presented, to encourage other immunological studies in schizophrenia research.

    T-lymphocyte subpopulations in schizophrenic patients (1990)
    Springer
    European archives of psychiatry and clinical neuroscience 239 (1990), S. 283-284

    Topics: Medicine
    Notes: Summary T-lymphocyte subpopulations were examined in the peripheral blood of 30 acute schizophrenic patients and compared with 30 age- and sex-matched patients with non-inflammatory neurological diseases. Significant increases in the numbers of Pan-T and T-helper cells were found in schizophrenic patients compared to the controls. The interindividual variability of values in the group of schizophrenic patients was greater than in the group of neurological patients.

    Computer-aided interpretation of mass spectra using databases with spectra and structures. I. Structure searchesDedicated to Professor Dr H. Budzikiewicz on the occasion of his 60th birthday. (1993)
    Chichester : Wiley-Blackwell
    Biological Mass Spectrometry 28 (1993), S. 198-206

    Notes: For databases containing spectra and structures of the reference compounds, structural descriptors (‘fragments’) have been derived that are used for structure searches in the databases. The 190 fragments have been defined according to the contents of the Wiley/NBS Mass Spectral Database and to fragmentation behaviour. A search for structures with defined fragments (absence or presence of certain fragments) retrieves certain classes of compounds. An application for checking a reference spectrum is discussed. A search for structures similar to a target structure has been developed to be used in cases where a structure can be proposed for the unknown compound. The most closely related structures existing in the database will be selected, the respective spectra often being the key for interpretation or structure elucidation, as illustrated by an example.

    Computer-aided interpretation of mass spectra by a combination of library search with principal component analysis (1990)
    New York, NY : Wiley-Blackwell
    Rapid Communications in Mass Spectrometry 4 (1990), S. 159-162 
    Details
    ISSN: 0951-4198
    Keywords: Chemistry ; Analytical Chemistry and Spectroscopy

    Topics: Physics
    Notes: The mass spectral set comprising the “hitlist” of a library search for spectra similar to that of an unknown is investigated by exploratory data analysis. Principal-component mapping is used to present the “hitlist” as a two-dimensional plot which allows an interactive classification of the unknown and the recognition of erroneous library spectra.

    Influence of crystalline structure and amorphous materials in the depth resolution of sputter etching (1993)
    Chichester [u.a.] : Wiley-Blackwell
    Surface and Interface Analysis 20 (1993), S. 1051-1054

    Notes: The dependence of depth resolution Δz/z on the sputtering angle θ is investigated for three sputter-deposited films: Cr (bee), SiNx (amorphous) and FeCoTb (amorphous). The depth resolution for the Cr system exhibits two maxima at θ = 35° and 45°. These are characteristic for bee textured material but different from fee textured material. The amorphous films show a very weak dependence, if any, owing to the absence of crystallites and crystalline texture. These results are in accordance with channeling theory.

    Effects of rotation and ion incidence angle on sputter depth resolution in thin films of NiFe/Ta (1992)
    Chichester [u.a.] : Wiley-Blackwell

    Notes: In an NiFe/Ta system, interface widths (Δz) are compared for sputter profiles with stationary and rotating sample holder (Zalar rotation). For low sputter angles, the Zalar rotation brings considerable improvements in Δz. For higher sputter angles, the improvement available through Zalar rotation vanishes as self-shadowing due to crystallites with less favorable orientation becomes the dominating rate mechanism. The improvement is further reduced for thinner films much below 1000 Å. For low sputter energies and films 125 Å thick, Zalar rotation has no influence. The limit of depth resolution was 30 Å, which resulted from the substrate-induced roughness of the NiFe/Ta interface. The interface width's maximum near 30° for stationary sputter etching is characteristic of sputter-deposited fcc films.
