    Notizen: [Auszug] Some classes of stars, including novae and supernovae, undergo explosive outbursts that eject stellar material into space. In 2002, the previously unknown variable star V838 Monocerotis brightened suddenly by a factor of ∼104. Unlike a supernova or nova, it did not ...

    Notizen: Summary The specific activities of the branched chain amino acyl-tRNA synthetases from the cytosolic and mitochondrial fractions ofN. crassa were low in dormant conidia and increased during germination, reaching a maximum 8 h after inoculation. This stage of development is characterised by high rates of many other cellular activities. The increases in activity of synthetases of both cytosol and mitochondria are inhibited by cycloheximide indicating that they are synthesized on cytoplasmic ribosomes. The mitochondrial synthetases show a stimulation of their specific activity when mitochondrial RNA and protein synthesis are inhibited by either ethidium bromide or chloramphenicol suggesting that a mitochondrial translation product regulates the synthesis of the mitochondrial synthetases. The activities of amino acyl-tRNA synthetases are dependent on energy production. When respiration is uncoupled from oxidative phosphorylation, synthetase specific activities decrease although the activities of other mitochondrial enzymes like NADH-dehydrogenase increase. This phenomenon suggests that more than one mechanism regulates the synthesis of mitochondrial proteins which are formed on cytoplasmic ribosomes. The synthesis of branched chain amino acyl-tRNA synthetases ofNeurospora is neither repressed by their cognate amino acids, nor is there inhibition by the precursors of these amino acids, as has been observed in other amino acyl-tRNA synthetases of various organism includingNeurospora.

    Notizen: Summary ¶ Purpose. In this prospective study the results of multimodal postoperative neuro-imaging were related to the survival of patients with high grade gliomas.  Methods. All 73 patients included underwent microsurgical tumour resection and had postoperative CT and transcranial sonography (TCS) examinations. In addition, 35 of the 73 patients received an early postoperative MRI. Patients were followed up for at least one year.  Findings. At the end of the 7 year study period 56 patients had died. The median survival time was 371 days. Survival rate was significantly higher in patients with anaplastic astrocytomas and inpatients displaying complete tumour resection on MRI (log-rank-test, p〈0.05) or a small postoperative residual tumour bulk on TCS (log-rank-test, p〈0.05). Cox proportional hazards model identified histological tumour grade, postoperative Karnofsky index, complete resection based on MRI and small postoperative residual tumour mass on TCS as independent predictors of survival.  Interpretation. This study demonstrates that early postoperative neuro-imaging has prognostic implications for the survival of patients with high grade gliomas. According to our results postoperative imaging with MRI and TCS is a valuable prognostic with regard to patient survival and should therefore be implemented in postoperative follow-up. It also helps to evaluate the efficacy of adjuvant therapy.

    Notizen: Abstract Eleven strains of obligately purinolytic clostridia have been studied with respect to their assignment to the three type strains of Clostridium acidiurici, C. cylindrosporum, and C. purinolyticum. DNA/DNA-hybridization proved to be the method of choice for differentiation whereas phenotypic characteristics such as spore morphology, substrate spectra, nutritional requirements, product formation, and sensitivity against various antibiotics did not allow unequivocal identification. All strains depended on selenite for growth.

    Notizen: Abstract By preselection of microorganisms which preferentially attack the side chain of cholesterol we have been able to isolate a mutant of Corynebacterium spec. Chol 73 which forms 20-carboxy-pregna-1,4-dien-3-one (BNC) from cholesterol in nearly quantitative yields. The structure of this compound has been established by means of13C NMR-,1H NMR and CD spectroscopy.

    Beschreibung / Inhaltsverzeichnis: Abstract. One particularly predominant current challenge to quantitative management science is the modeling and analysis of competitive actions and reactions. Approaches following the stimulus response paradigm are able to take into account the limited access to a company's internal decision making processes. In the present paper the most significant characteristics of a behavioristic analysis of competitive reactions are described. Furthermore, a stochastic model of competitive reactions by the simultaneous use of several marketing instruments is proposed. The empirical evidence of the model will be demonstrated with POS scanner data on frequently purchased consumer goods.
    Notizen: Zusammenfassung. Eine der vordringlichsten gegenwärtigen Herausforderungen an die quantitative Management-Wissenschaft ist die Modellierung und Analyse von Wettbewerbsaktionen und -reaktionen. Dem begrenzten Zugang zu unternehmensinternen Entscheidungsprozessen kann durch die behavioristische Modellierung des Wettbewerbsverhaltens entsprechend dem Stimulus-Response-Paradigma Rechnung getragen werden. Im vorliegenden Beitrag werden wesentliche Charakteristika der behavioristischen Analyse von Wettbewerbsreaktionen dargestellt. Darüber hinaus wird ein stochastisches Modell der Wettbewerbsreaktion durch den simultanen Einsatz verschiedener Marketinginstrumente vorgestellt. Die empirische Überprüfung des Modells erfolgt anhand eines POS-Scannerdatensatzes für ein Konsumgut des täglichen Bedarfs.
