    Notizen: A laboratory experiment examined the effects of applying decision support system (DSS) technology to decision making in ill-structured problem environments under varying information conditions. Marketing executives participated in the experiment which investigated the effects of DSS availability, DSS training, and data availability on dependent variables that included: (1) the number of alternatives considered by a subject during decision making, (2) the period of time spent by a subject to complete the decision-making process, (3) the subject's perceived confidence in the decisions he or she had made, (4) the amount of data considered by a subject's during decision making, (5) the individual subject's decision processing, and (6) the subject's performance overall. Our results indicate that all three factors significantly affect the number of alternatives considered by subjects during the decision-making process. We therefore suggest that DSS training be coordinated with decision training in order to realize the potential of DSSs as described in the DSS literature.

    Beschreibung / Inhaltsverzeichnis: Résumé Avec un taux de réussite de près de 70%, la transplantation de foie est reconnue comme étant la méthode thérapeutique des stades terminaux en pathologie hépatique, en particulier chez l'enfant où les indications sont parfois mieux définies que chez l'adulte. Le facteur limitant reste cependant la disponibilité en donneur de foie chez l'enfant. Actuellement la principale indication de transplantation hépatique en pédiatrie est l'atrésie biliaire extrahépatique. Les autres pathologies pédiatriques bénéficiames de cette technique sont représentées par des pathologies chroniques et obstructives du foie, les tumeurs primitives du foie, des pathologies métaboliques telles que le déficit en alpha-1-antitryspine, la maladie de Wilson, le syndrome de Criggler-Najjar et la tyrosinémie, ainsi que les insuffisances hépatiques aiguës d'origine virale ou toxique. La transplantation de foie n'est plus seulement une technique expérimentale mais elle est devenue une thérapeutique en elle-même. Ceci résulte en grande partie de l'amélioration des techniques chirurgicales, des soins pré-, peret postopératoires et des thérapeutiques immunosuppressives par la cyclosporin.
    Kurzfassung: Resumen El transplante hepático se ha convertido en una modalidad terapeutica aceptada para el tratamiento de pacientes con enfermedad terminal hepática. La supervivencia al año es alrededor del 70 porciento. Esta modalidad terapeútica es más aceptada en pacientes pediátricos en quienes las indicaciones están mejor definidas que en los adultos. El factor limitante continúa siendo la disponibilidad de hígados pediátricos. Actualmente la indicación principal para este procedimiento en niños es la atresia de vias biliares. Otras enfermedades tratadas por esta modalidad son las enfermedades hepáticas crónicas obstructivas, las malignidades primarias hepáticas, varios trastornos producidos por fallas congénitas del metabolismo como la deficiencia alfa1 antitripsina, la enfermedad de Wilson, el síndrome de Crigler-Najjar y la tirosinemia y el fallo hepático agudo o subagudo causado por agentes virales o hepatotóxicos. El paso del transplante hepático de un procedimiento experimental a una modalidad terapeútica aceptada ha sido el resultado de adelantos en la técnica operatoria, el manejo perioperatorio, y el mayor uso de la ciclosporina.
    Notizen: Abstract Liver transplantation has become the accepted mode of therapy for the patient with end-stage liver disease, with a 1-year success rate of approximately 70%. This is particularly true in the child in whom the indications are sometimes more clear cut than in the adult patient. The limiting factor to transplantation, however, remains the availability of suitable pediatric donor livers. Presently, the major indication for pediatric liver transplantation is extrahepatic biliary atresia. Other diseases in the pediatric patient treatable by this modality are chronic obstructive liver diseases, primary tumors of the liver, and a variety of metabolic disorders such as alpha-1-antitrypsin deficiency, Wilson's disease, Crigler-Najjar syndrome, and tyrosinemia, as well as acute and subacute hepatic failure resulting from viral or toxin insult. Liver transplantation is no longer an experimental procedure but now is an accepted therapy. This has resulted in large part because of improved surgical techniques, perioperative management, and immunosuppressive therapy with cyclosporin.

    Notizen: [Auszug] SIR-In Conrad Lichtenstein's otherwise excellent short comment on tumour induction by Agrobacterium tumefaciens1, he omitted to mention the biological context of the bacterium. Wounding is a prerequisite for tumour formation, the basis for which is that wounded cells release inducers, such as ...

    Notizen: Summary Injection of low-viscosity resin was used to identify in situ functional blood vessels at the margins of developing regional myocardial infarcts. The ventral interventricular branch (VIB) of the left coronary artery was occluded for 0–240 min in 20 isolated perfused rabbit hearts. After perfusion fixation with glutaraldehyde, resin was injected into the coronary arteries—that injected into the VIB contained dispersed lead dioxide and that injected into the remainder of the heart contained Fat Red 7B dye. This allowed macroscopic and microscopic identification of functional blood vessels. Following transmural freeze fracture, left ventricles were examined using back-scattered electron imaging in a scanning electron microscope. Close to 60% of capillaries in nonischemic myocardium allowed the passage of resin. Thirty minutes of ischemia produced a hyperemic increase to 80%–90% in the proportion of filled vessels. After 60 min, however, a severe reperfusion defect corresponding to the “no-reflow” phenomenon had developed, with virtually all vessels collapsed and 〈10% functional. Among the structurally normal myocytes adjacent to the infarct margin there was a significant reduction (to 30%–40%) in the proportion of functional capillaries. This was due to groups of dilated vessels which were not accessible to arterial supply. Although these marginal “low-flow” regions were of small volume at any one point in time, they seem likely to contribute to the progression of ischemic necrosis, and are probably nonfunctional due to the compression of their venous drainage traversing the infarct.

    Notizen: Summary During test baking, the wheat line QT2870, bred from a rye-derived parent, Kavkaz, and having the pedigree Kavkaz/Timgalen//3*Oxley, showed excessive dough stickiness when slightly overmixed. Conventional quality tests on QT2870 and three commercial varieties did not show any major differences which could explain this dough stickiness. However, resistogram data for QT2870 were considerably different from those for the other cultivars. The curves for QT2870 had lower breaking points and sharper curve angles, indicating that it had a lower tolerance to high speed mixing than the other varieties. Dough stickiness and a lack of mixing tolerance are likely to be major problems limiting the use of rye-derived parents in Australian bread wheat breeding programmes.

    Notizen: Abstract Color vision abnormalities indicated by the Farnsworth-Munsell 100-hue Color Vision Tests (FM-100) were analyzed by computer to better characterize and group congenital and acquired color vision disorders and to help establish statistically significant diagnostic criteria. Standard evaluation of the FM-100 is by axis and error score calculations. A method has been established for computer-averaging many tests from patients with the same color abnormalities determined by history, standard FM-100 and Nagel anomaloscope. The computer calculated an average error score and standard deviation for each of the 85 color caps. Every time a new patient was evaluated for color vision abnormality, his score was compared with averaged tests with common diagnoses, by calculating distance scores. The averaged test with the lowest distance score consistently tended to coincide with the diagnosis. An analysis of 130 FM-100 color tests found technician-calculated error scores to be incorrect, although usually minor, in 40% of the tests. The computer-calculated axes agreed well with the technician's estimates. The distance scores predicted the diagnosis accurately 89% of the time. Many errors were due to the small number of protanopes averaged and inability to distinguish trichromats from dichromats.

    Notizen: Summary A series of safe, simple and single-staged reconstructions following radical resection of maxillary antral carcinomas with soft tissue involvement is presented. These reconstructions were performed using free triple-folded latissimus dorsi myocutaneous flaps revascularised via the facial vessels. This technique can be safely used in irradiated patients and, when indicated, allows for the administration of early postoperative radiotherapy, thus improving the potential cure rate. Advantages and disadvantages of the technique are discussed.
