    Treatment with allyl alcohol selects specifically for mutants of Clostridium acetobutylicum defective in butanol synthesis (1986)

    Notes: 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.

    Controlled generation of single photons from a strongly coupled atom-cavity system (1999)

    Notes: Abstract. We propose a new method for the generation of single photons. Our scheme will lead to the emission of one photon into a single mode of the radiation field in response to a trigger event. This photon is emitted from an atom strongly coupled to a high-finesse optical cavity, and the trigger is a classical light pulse. The device combines cavity-QED with an adiabatic transfer technique. We simulate this process numerically and show that it is possible to control the temporal behaviour of the photon emission probability by the shape and the detuning of the trigger pulse. An extension of the scheme with a reloading mechanism will allow one to emit a bit-stream of photons at a given rate.

    Periorbitales Ödem als Initialsymptom eines Lupus erythematodes profundus (1999)

    Description / Table of Contents: Summary Periorbital edema may occur initially or in the course of a wide variety of diseases. One of these diseases is lupus panniculitis, a variant of lupus erythematosus, characterized by firm subcutaneous nodules that may ulcerate with subsequent scar formation. We present a case of lupus panniculitis in which the periorbital edema was the initial manifestation. Knowledge about the differential diagnostic possibilities of periorbital edema as well as the different variants of cutaneous lupus erythematosus is important to reach the correct diagnosis.
    Notes: Zusammenfassung Das periorbitale Ödem ist ein Symptom, das initial oder im Verlauf von Erkrankungen verschiedenster Genese auftreten kann. Eine mögliche Assoziation stellt der Lupus erythematodes profundus dar. Diese Krankheit ist durch subkutane knotige und plattenartige Infiltrate gekennzeichnet, welche zu Ulzerationen und narbigen Einziehungen führen können. Anhand eines Fallberichts wird aufgezeigt, daß ein periorbitales Ödem als Initialsymptom den typischen Hautveränderungen eines Lupus erythematodes profundus vorausgehen kann. Die Kenntnis der möglichen Differentialdiagnosen bei periorbitalem Ödem sowie der unterschiedlichen Varianten eines Lupus erythematodes ist für die Diagnosestellung von entscheidender Bedeutung.

    Genetic variation of an acid phosphatase (Acp-2) in the laboratory rat: Possible homology with mouse AP-1 and human ACP2 (1986)

    Notes: Abstract A genetic locus controlling the electrophoretic mobility of an acid phosphatase in the rat (Rattus norvegicus) is described. The locus, designed Acp-2, is not expressed in erythrocytes but is expressed in all other tissues studied. The product of Acp-2 hydrolyzes a wide variety of phosphate monoesters and is inhibited by l(+)-tartaric acid. Inbred rat strains have fixed either allele Acp-2a or allele Acp-2b. Codominant expression is observed in the respective F1 hybrids. Backcross progenies revealed the expected 1:1 segregation ratio. Possible loose linkage was found between the Acp-2 and the Pep-3 gene loci at a recombination frequency of 0.36±0.06.
