    Nanoprobe-induced electrostatic lateral quantization in near-surface resonant-tunneling heterostructures (1995)

    Notizen: We report experimental and theoretical evidence for electrostatic lateral confinement induced by a nanoprobe. The lateral confinement is manifest as oscillations of the differential conductance of a near-surface resonant-tunneling heterostructure in air at room temperature. © 1995 American Institute of Physics.

    METHOD FOR EVALUATING THE FILTERABILITY OF WINE AND SIMILAR FLUIDS. (1976)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 41 (1976), S. 0 
    Details
    ISSN: 1750-3841
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Land- und Forstwirtschaft, Gartenbau, Fischereiwirtschaft, Hauswirtschaft , Werkstoffwissenschaften, Fertigungsverfahren, Fertigung
    Notizen: A method for determination of the filterability of wine was developed. The method is based on evaluation of the filtration curve of a wine filtered through a membrane disc 13 mm in diameter, having a pore size of 0.45 micron. Results of the filterability test were found to be related to plant operation. According to the method developed, a wine is ready for membrane filtration the moment that its filterability test indicates that the differential filtered volume remains unchanged for most of the 60 min determination time. A decrease in the differential filtered volume indicates that the wine contains insolubles/microorganisms, and the rate of the decrease should be considered to be proportional to the load on the membrane. This method is not limited to the wine industry, but can be adapted and/or modified for similar applications, i.e., pharmaceuticals, breweries, fine chemicals.

    The Utilization of Glucose and Proline by Culture Forms of Trypanosoma brucei (1972)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 19 (1972), S. 0 
    Details
    ISSN: 1550-7408
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Biologie
    Notizen: Exponentially dividing culture forms of Trypanosoma brucei did not utilize glucose provided in the culture medium. The inclusion of 2-deoxyglucose in the medium had no effect on the growth of the trypanosomes. Glucose could be replaced by proline in the liquid phase of biphasic medium without affecting the doubling time of the organisms. Proline added to the culture medium in this way disappeared during the log phase of growth. Glucose in the culture medium was used by the trypanosomes only when the stationary growth phase had been reached. Lipid accumulated in stationary phase trypanosomes grown in glucose-containing medium, but there was no lipid accumulation in log phase organisms or in those which had been grown in proline-containing medium. Bloodstream trypanosomes transferred to liquid medium rapidly utilized glucose over the first 12 hr of culture, and this was accompanied by an accumulation of free pyruvate in the medium. The rate of glucose utilization fell off over the next 36 hr; this was accompanied by a lowering of free pyruvate in the medium and a rise in the proline oxidase activity of the trypanosomes. The possible biologic significance of proline to trypanosomes developing in the midgut of the tsetse vector is discussed.

    The Effect of Diphenylamine on Terminal Respiration in Bloodstream and Culture Forms of Trypanosoma brucei (1972)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 19 (1972), S. 0 
    Details
    ISSN: 1550-7408
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Biologie
    Notizen: SYNOPSIS. Diphenylamine was shown to be a potent inhibitor of cyanide insensitive respiration in both bloodstream and newly established culture forms of the same isolate of Trypanosoma brucei, with the L-α-glycerophosphate oxidase system having the greatest sensitivity to the inhibitor. The NADH oxidase activity of bloodstream forms was at least twice as sensitive to diphenylamine as the corresponding activity in culture forms, suggesting different routes of NADH oxidation in the 2 forms. The oxidation of L-α-glycerophosphate was inhibited to a similar degree in both culture and bloodstream forms. L-α-glycerophosphate oxidation in bloodstream forms differed from that found in culture forms in that the bloodstream system, unlike that in the culture form, was unable to donate electrons to cytochrome c. In culture form trypanosomes there was a distinct difference in the degree of diphenylamine inhibition on the oxidation of L-α-glycerophosphate, NADH, and succinate, suggesting the participation of separate flavoproteins in the oxidation of these substrates.

    m-Chlorobenzhydroxamic Acid–an Inhibitor of Cyanide-Insensitive Respiration in Trypanosoma brucei (1973)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 20 (1973), S. 0 
    Details

    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Biologie
    Notizen: Cyanide-insensitive respiration of bloodstream and culture forms of T. brucei was inhibited by m-chlorobenz-hydroxamic acid (m-CLAM). The cyanide-sensitive respiration of culture forms of this organism was not affected by m-CLAM. This compound is the 1st really effective inhibitor to be described that acts specifically on the cyanide-insensitive respiration of the T. brucei group of trypanosomes; as such it may be of some importance as a trypanocidal drug.Evidence is adduced which suggests that a branched electron transport chain is present in culture forms of T. brucei and that the cyanide-insensitive terminal oxidase found in these stages is the same as that found in bloodstream forms.
