    The Involvement of Kupffer Cells in the Clearance of High Molecular Weight Rat IgA Aggregates in Rats (1990)

    Notizen: In the present study the clearance kinetics and tissue distribution of aggregated 125I-labclled monoclonal rat IgA ([125I] AIgA) of different sizes were studied in rats. Soluble [125I]AIgA disappeared from the circulation in a biphasic manner with an initial rapid distribution half-life (TI) and a second slower half-life (T2). T2 was directly related to the size of the aggregates. High molecular weight [125I]AIgA, containing 10–12 IgA molecules per aggregate ([lgA]10–12). was cleared much faster than low molecular weight aggregates. The main site of clearance was the liver. The larger the size of the AIgA, the more degradation products were found in the circulation. After injection of [[lgA]10–12, non-parenchymal cells (NPC) contained three times more radioactivity than parenchymal cells(PC)(NPC:P ratio 3.06 ± 0.96). Ratios of 0.82 ± 0.0.3 and 0.62 ± 0.12 were observed when [IgA]5–6 and [IgA]2 were injected respectively, suggesting a greater role for Kupffer cells in the clearance of large-sized IgA aggregates. Kupffer cells were shown to be the main cells for localization of large-sized AIgA established by immunohistochemical staining on liver cryostat sections.

    Fatal bleeding from duodenal varices as a late complication of neonatal thrombosis of the inferior vena cava (1992)

    Thema: Medizin
    Notizen: Summary A 21-year-old man was hospitalized with repeated bleeding from the gastrointestinal tract, the cause of which could not be detected by gastroscopy, colonoscopy or arteriography. After the third surgical intervention he died of uncontrollable bleeding. At autopsy, marked and partly ulcerated duodenal varices were found to be the cause of the bleeding. They were part of a collateral circulation that had developed from chronic obstruction of the inferior vena cava, where thrombosis had arisen in association with neonatal renal vein thrombosis. There was consecutive renal infarction which had required a left nephrectomy on the 2nd day after birth.

    Cometabolic degradation of chloroallyl alcohols in batch and continuous cultures (1994)

    Details

    Thema: Biologie , Werkstoffwissenschaften, Fertigungsverfahren, Fertigung
    Notizen: Abstract The biodegradation of chloroallyl alcohols by pure and mixed bacterial cultures was investigated. Only 2-chloroallyl alcohol and cis– and trans–3-chloroallyl alcohol served as growth substrate for pure cultures. The other chloroallyl alcohols could be cometabolically degraded during growth on 2-chloroallyl alcohol. Cometabolic degradation of trichloroallyl alcohol, which was the most recalcitrant congener, by a Pseudomonas strain isolated on 2-chloroallyl alcohol resulted in 60% dechlorination. Efficient degradation of a mixture of chloroallyl alcohols in continuous culture could only be achieved in the presence of a satellite population. The mixed culture degraded 99% of the total chloroallyl alcohols added with 71% chloride release. The culture contained strains with a new catabolic potential. The results indicate the importance of mixed cultures and genetic adaptation for efficient chloroallyl alcohol removal.

    The application of the linearized boltzmann transport equation to low energy atomic collisions in solids (1992)
    Springer
    The European physical journal 88 (1992), S. 63-70 
    Details
    ISSN: 1434-6036
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Physik
    Notizen: Abstract A new method has been developed for the solution of the linearized Boltzmann equation far from thermal equilibrium. The solution has been applied to the interpretation of the slowing down of atoms with kinetic energies of a few hundreds of eV as obtained from measured γ-peak profiles, using the gamma ray induced doppler broadening (GRID) technique. From this solution, lifetimes of nuclear excited states can be extracted. These results are compared with the predictions of other models.

    On some aspects of selfconsistent RPA theory (1991)
    Springer
    The European physical journal 339 (1991), S. 43-50 
    Details
    ISSN: 1434-601X
    Schlagwort(e): 21.60.Ev
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Physik
    Notizen: Abstract The aim of selfconsistent RPA theory is to completely avoid the quasiboson approximation. In order to do this without explicit knowledge of the groundstate wave function a selfconsistent system of equation for the two body density matrix has been set up. For the Lipkin model we solved these equations for two cases(i) quasi spin symmetry is conserved and(ii) quasi spin symmetry is broken. In case(i) we obtain excellent results for the groundstate energies, whereas case(ii) is good only for strong values of the interaction strength. We briefly indicate how our approach can be generalised to the pairing case.

    Excited level lifetime measurements following very low energy nuclear recoils (1992)
    Springer
    Hyperfine interactions 75 (1992), S. 533-542 
    Details
    ISSN: 1572-9540
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Physik
    Notizen: Abstract Using high resolution gamma spectroscopy it is possible to observe Doppler broadening of gamma transitions from excited states which have themselves been populated after emission of gamma photons or other low energy nuclear radiation. This allows the determination of the lifetimes of these intermediate states, providing the time dependence of the recoil velocities is known. Conversely, if the lifetime is well known, this technique may be used to study the recoil process itself (and hence the atomic interaction) at energies of only a few times the lattice binding energy.
