    Notizen: Summary Background Lupus erythematosus tumidus (LET), a photosensitive skin disorder with characteristic clinical and histological features, has not been generally accepted as a subset of cutaneous lupus erythematosus (CLE). Objectives To analyse the expression of epidermal surface molecules in skin biopsy specimens from patients with LET and to relate the results to other variants of CLE, such as discoid lupus erythematosus (DLE) and subacute CLE (SCLE). Methods In total, 45 patients with different subtypes of CLE were included in the study, and cryostat sections from primary and ultraviolet (UV) A- and UVB-induced skin lesions were investigated using immunohistochemical methods. Results In contrast to healthy controls, skin lesions of LET showed upregulation of intercellular adhesion molecule-1 (ICAM-1) and histocompatibility class II molecules (HLA-DR), with an expression pattern resembling that seen in DLE and SCLE. Furthermore, staining with a monoclonal antibody against 27E10, a distinct marker for cell activation and differentiation, revealed intense focal or band-like labelling of all epidermal layers independent of the type of lesion. Conclusions Expression of epidermal surface molecules such as ICAM-1, HLA-DR and 27E10 is equally upregulated in primary and UV-induced lesions of patients with LET, DLE and SCLE. These results support our recent clinical findings that LET represents a distinct subset of CLE with a similar immunopathomechanism rather than a different disease.

    Treatment with allyl alcohol selects specifically for mutants of Clostridium acetobutylicum defective in butanol synthesis (1986)
    Oxford, UK : Blackwell Publishing Ltd
    FEMS microbiology letters 36 (1986), S. 0 
    Details
    ISSN: 1574-6968
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Biologie
    Notizen: Abstract Treatment of Clostridium acetobutylicum with allyl alcohol allowed the selection of mutants which were unable to produce n-butanol, whereas the synthesis of acetone and ethanol was unaffected. Enzymatic investigations revealed that all mutant strains were devoid of butyraldehyde dehydrogenase or showed a very low activity of this enzyme as compared to the wild type.

    Notizen: Abstract A short review of the methods of preparation of magnetite anodes and the physico-chemical properties of Fe3O4 is followed by experimental results using chlorine evolution as a test reaction. Problems arising in the operation of composite magnetite-titanium structures are considered.

    The role of electrode structure and surface texture in the performance of gas evolving electrodes (1979)
    Springer
    Journal of applied electrochemistry 9 (1979), S. 765-775 
    Details
    ISSN: 1572-8838
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Chemie und Pharmazie , Elektrotechnik, Elektronik, Nachrichtentechnik
    Notizen: Abstract The literature on gas-evolving electrodes is reviewed. Cell voltage measurements are reported for an undivided cell in NaOH at 70° C in which the cathode was mild steel plate, mild steel mesh or composites of both these materials. The anode was Ni-plated mild steel sheet or mesh. Variation in the structure of one electrode, leaving the other unchanged allowed changes in overvoltage to be measured. It is shown that substantial voltage reductions can be obtained using multiplex electrode structures and that these are mainly explicable in terms of specific surface areas. Sheet electrodes are seen to be more efficient than mesh ones on this basis however. It is shown that sheet electrodes with very high specific surface areas show significantly higher overvoltages than electrodes of low specific area and this surprising result is interpreted in terms of bubble entrapment.

    A multi-purpose microprocessor-based electrochemical apparatus (1978)
    Springer
    Journal of applied electrochemistry 8 (1978), S. 437-443

    ISSN: 1572-8838
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Chemie und Pharmazie , Elektrotechnik, Elektronik, Nachrichtentechnik
    Notizen: Abstract A microprocessor-linked programmable calculator instrument is described. Current-voltage readings taken at predetermined intervals of time can be read, stored and passed to the calculator where they may be processed to yield Tafel slope data, ohmic drops, areas under curves (for cyclic voltammetry) or used in open-circuit decay calculations. The results may also be fed to a paper-tape punch for storage or graphplotting using a larger computer.

    Current efficiency losses in indirect electrochemical processing (1979)
    Springer
    Journal of applied electrochemistry 9 (1979), S. 777-782 
    Details
    ISSN: 1572-8838
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Chemie und Pharmazie , Elektrotechnik, Elektronik, Nachrichtentechnik
    Notizen: Abstract The various reasons for current efficiency losses in indirect electrochemical processing are considered. Using the Cr(VI) oxidation ofo-toluene sulphonamide as a model, it is shown that accretion of organic residues is an important factor contributing to current efficiency losses. Other evidence is provided to suggest that film formation on the electrode surface acts selectively to promote oxygen evolution rather than Cr(III) re-oxidation.
