    Notes: Die rot-grüne Koalition hat die Eckpunkte der geplanten Gesundheitsreform 2000 bekanntgegeben. Die Kassen sollen künftig eine wichtigere Rolle bei der Honorarverteilung spielen. Denn die ärztliche Selbstverwaltung habe eine gerechte Verteilung der Geldmittel bislang nicht zustande gebracht, so Bundesgesundheitsministerin Andrea Fischer. Ob die Kassen dazu imstande und willens sind? Besser wäre es, eine Demokratisierung der KVen voranzutreiben. Dr. Jürgen Fischer, BDR-Vorsitzender, über die Vorstellungen, die der BDR in die laufende Diskussion einbringt.

    Notes: Summary In this paper duality theory is used to derive an algorithm for the solution of the discrete linearL p approximation problem (for 1〈p〈2). This algorithm turns out to be similar to existing iteratively reweighted least squares algorithms, but can be shown to be globally andQ-superlinearly convergent.

    Sulphur- and nitrogen-containing volatile components of kohlrabi (Brassica oleracea var.gongylodes L.) (1992)
    Springer

    Description / Table of Contents: Summary Volatiles from the edible part of kohlrabi (Brassica oleracea var.gongylodes) were isolated by means of a dynamic headspace sampling device and separated by capillary gas chromatography. For identification samples were subjected to element-specific detection (Flame photometric and nitrogen-phosphorus detectors) and mass spectral analyses. Major volatile products are: 3-methylthiopropyl, 4-methylthiobutyl and allyl isothiocyanate. The two corresponding organic cyanides 3-methylthiopropyl and 4-methylthiobutyl cyanides and dimethyl, trimethyl and tetramethyl disulphides are also present in higher amounts.n-Nonenal, (E)-2-hexenal, (E,E)-2,4-heptadienal and some isothiocyanates of unknown structure appear in the volatile fraction as minor constituents. The sulphur- and nitrogen-containing components could be related to the enzymic cleavage (myrosinase) of glucosinolates, naturally occurring precursors in brassica plants. Some of the volatile products possess antimicrobial and antithyroid effects and have been identified in different plants of the cruciferae family. The possible role of the isothiocyanates, cyanides, sulphides and aldehydes to the flavour of kohlrabi is discussed.
    Notes: Zusammenfassung Die flüchtigen Inhaltsstoffe des Kohlrabi (Brassica oleracea var.gongylodes L.) wurden mittels der dynamischen Kopfraum-Technik isoliert und anschligßend gaschromatographisch aufgetrennt. Unter Anwendung elementspezifischer Detektoren (FPD, NPD) und Massenspektrometrie erfolgte deren Identifizierung. Zu den Hauptkomponenten gehören: 3-Methylthiopropyl-,4-Methylthiobutyl- und Allyrisothiocyanat. Die beiden korrespondierenden organischen Cyanide 3-Methylthiopropyl- und 4-Methylthiobutyl-cyanid sowie Dimethyldisulfid, Dimethyltrisulfid und Dimethyl-tetrasulfid erscheinen ebenfalls in gröσBeren Mengen. In geringerer Konzentration treten nochn-Nonenal, (E)-2-Hexenal, (E,E)-2,4-Heptadienal und einige Isothiocyanate unbekannter Struktur in den Extrakten auf. Die schwefel- und stickstoffhaltigen Komponenten sind auf die enzymatische Spaltung (Myrosinase) der inBrassica-Arten vorhandenen Glucosinolate zurückzuführen. Einige der identifizierten Stoffe zeigen antimikrobielle und antithyroide Eigenschaften und wurden in verschiedenen Cruziferenarten nachgewiesen. Die mögliche Bedeutung der Isothiocyanate, Cyanide, Sulfide und Aldehyde für das Kohlrabiaroma wird diskutiert.

    Correction of aerosol influence in Landsat 5 Thematic Mapper data (1994)

    Notes: Abstract The influence of aerosols in the visible and near infrared part of the electromagnetic spectrum was studied by simulations of Landsat 5 Thematic Mapper measurements. The radiative transfer model used is based on the matrix-operator-method and was applied to different surface types, represented by specific spectral albedo values. On the basis of a single scattering approach for atmospheric correction, an algorithm was developed to correct for the influences of aerosols, air molecules and athmospheric trace gases on Thematic Mapper measurements above land surfaces using additional measurements above nearby located ocean surfaces to estimate the optical properties. The optical thickness of a cloud-free atmosphere has therefore been varied in the model for different aerosol types and surface reflectances.

    Hepatocellular metabolic change after orthotopic liver transplantation in rats (1991)

    Notes: Abstract The hepatocellular metabolic change after liver transplantation following 2 hr cold ischemia was investigated. Of 55 orthotopic liver transplantations in male Wistar rats, 47 animals were sacrificed at 3 hr, and 1, 2, 7 and 30 days to determine hepatic metabolite levels, in the form of adenine nucleotides, lactate and glycogen. Using the other 8 recipients, biochemical examinations were done at 1, 3, 5, 7, 30 and 60 days and metabolic levels estimated at 60 days. The SGOT and SGPT levels decreased gradually after a remarkable increase on the first postoperative day, while the alkaline phosphatase level revealed a peak value at 30 days. All levels recovered to within the normal range in 60 days. The total adenine nucleotide level reached the normal range within 3 hr following the blood reflow and remained at a normal level thereafter. However, all the metabolic levels apart from total adenine nucleotides deteriorated to reach their worst level at 7 days. The results of this investigation indicate that the posttransplanted deterioration of metabolic levels were possibly caused by the imperfect oxygenation due to cellular edema after blood reflow. However, the levels of these metabolites recovered within 60 days after transplantation.

    Role of vindesine in induction chemotherapy in locally-advanced non-small-cell lung cancer (1998)

    Topics: Medicine
    Notes: Abstract Locally advanced non-small-cell lung cancer (NSCLC) in most cases is not curable at the present time. Owing to the local extent of the tumor, the rate of complete resections is low and, therefore, survival in these patients is poor. For this reason, induction chemotherapy is being investigated in patients expected to have a poor prognosis after standard surgery and radiotherapy. The rationale for induction chemotherapy is to increase the rate of complete resections and achieve early elimination of micrometastases. Clinical investigations have reported an improvement of survival in stage III NSCLC after induction chemotherapy by using different combinations of cytotoxic drugs. Vindesine ranks among the most active single agents in this disease and has been part of a number of combination regimens in induction chemotherapy. The combination of mitomycin, vindesine or vinblastine and cisplatin has produced encouraging results in several studies, indicating a possible improvement of survival in stage III NSCLC, although its superiority to other combinations yet has to be demonstrated.

    Notes: Abstract cDNA clones encoding cysteine proteinases from cotyledons of germinated seeds of Vicia sativa L. have been obtained by means of PCR. Degenerate oligonucleotide primers were designed according to conserved amino acid regions of known cysteine proteinases. The deduced amino acid sequences of the cDNA clones encoding VSCYSPR1 and VSCYSPR2 display strong homology to cysteine proteinases of the so called papain superfamily. Northern analyses revealed developmentally regulated expression of both the mRNAs in germinating seeds. The transcripts were shown to be products of two distinct single genes, each exhibiting structural polymorphisms as exposed in few nucleotide substitutions.

    Nonvagal origin of galanin-containing nerve terminals innervating striated muscle fibers of the rat esophagus (1998)

    Notes: Abstract  We investigated the origin of galanin-positive nerve fibers on motor endplates in rat esophagus using anterograde 1,1′-dioleyl-3,3,3′,3′-tetramethylindocarbocyanine methane sulfonate (DiI) tracing from the nucleus ambiguus combined with galanin immunocytochemistry and calcitonin gene-related peptide immunocytochemistry. To demonstrate spatial relationships of galanin-positive nerve fibers to vagal and enteric nerve fibers on motor endplates, we combined galanin immunocytochemistry with calcitonin gene-related peptide immunostaining for labeling of vagal terminals, and vasoactive intestinal peptide immunoreactivity and NADPH-diaphorase histochemistry for demonstration of enteric nerve fibers. Within fine varicose nerve fibers, galanin was colocalized with vasoactive intestinal peptide and NADPH-diaphorase to a high degree and turned out to be completely separated from calcitonin gene-related peptide-positive or anterogradely DiI-labeled vagal motor terminals. These results indicate that the enteric nervous system is the most important and possibly the only source of galanin-positive nerve terminals on motor endplates in rat esophagus. Galanin may be, in addition to nitric oxide and vasoactive intestinal peptide, a mediator of the enteric coinnervation of striated muscle in this organ.
