    On the developmental dependence between Cyanophora paradoxa and Cyanocyta korschikoffiana in symbiosis (1982)
    Springer
    Planta 155 (1982), S. 190-192 
    Details
    ISSN: 1432-2048
    Keywords: Cyanobacteria ; Cyanocyta ; Cyanophora ; Endosymbiosis ; Regulation (development)

    Topics: Biology
    Notes: Abstract The prokaryote Cyanocyta korschikoffiana was isolated from the eukaryote Cyanophora paradoxa. The synthesis of several thylakoid proteins in these cyanelles is influenced by light and darkness and is sensitive to cycloheximide, the inhibitor of the eukaryotic host's translation. The possibility of a direct coordination between the translations of the host and of the cyanelles is discussed.

    Description / Table of Contents: Zusammenfassung Auf der Basis von 3822 Cholecystektomien, die entsprechend einer einheitlichen Technik ohne Cholangiomanometrie und -skopie mit ergänzender Papilloplastik vorgenommen wurden, erfolgt eine restrospektive Analyse. Der Analyse liegen zwei randomisierte Stichproben von je 237 Patienten aus dem Zeitraum von 1970–1977 zugrunde. 96% der Patienten sind beschwerdefrei oder deutlich gebessert. 4%. geben nachuntersuchungswürdige Beschwerden mit kolikartigen Schmerzattacken an. In der Hälfte der Fälle kann eine organische Ursache außerhalb der Gallenwege nachgewiesen werden.
    Notes: Summary In a study founded on two random samples of 237 patients each from 1970–1977, 96% of the patients have had no complaints or they have felt much better after simple cholecystectomy. Retrospective analysis of 3822 patients with a standardized simple cholecystectomy with papilloplasty and without cholongiometry and cholangioscopy shows that only 4% have attacks of pain in the right side of the upper abdomen. In half of the cases an organic reason was found which had no connection with the bile duct.

    On the centre-to-limb variation and latitude dependence of the asymmetry and wavelength shift of the solar line λ 5576 (1982)
    Springer
    Solar physics 79 (1982), S. 3-18

    Notes: Abstract Low noise photoelectric measurements of the line profile of the g = 0 Fe line gl 5576.097 combined with determinations of the wavelength shift of its centre calibrated by use of an I 2 absorption tube are reported. Measurements taken at various limb distances (1.0 ≤ cos ϑ ≤ 0.2) and along 4 different diameters of the Sun are used to investigate the behaviour of the line asymmetry (C-shape) and wavelength shift of the line centre as functions of cos ϑ and of latitude and to search for possible pole-equator differences. An accuracy of approx. 0.8 mÅ r.m.s. is achieved for the determination of the centre of the solar line relative to the iodine lines and of 0.3 mÅ to 1 mÅ r.m.s. for the relative variations of the C-shape. The analysis shows a significant difference between the limb-effect curves along polar and equatorial diameters for cos ϑ ≤ 0.4 and changes of the C-shape for 0.9 ≥ cos ϑ ≥ 0.6 with a rather strong indication of a latitude dependence of the C-shape. This latitude dependence may account for the so-called ‘ears’ observed by Howard et al. (1980) who used the well-known Doppler compensator method which integrates the line asymmetry from the line wings to the core.

    Chloroplastenreduktion inEuglena gracilis durch heterotrophe Ernährung mit Glucose im Licht (1981)
    Springer
    Protoplasma 106 (1981), S. 317-327 
    Details
    ISSN: 1615-6102
    Keywords: Chlorophyll-protein-complex ; Chloroplast differentiation ; Euglena gracilis ; Glucose
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary In order to investigate the chloroplast reduction inEuglena gracilis, strain z during heterotrophic nutrition, the changes induced by glucose on the cellular amounts of chlorophyll, protein and carbohydrates are analysed as well as the variations of the size of chloroplasts and of the molecular composition of the thylakoids. At the 6th hour of the cell-cycle autotrophically cultured and with a light-dark-change of 14∶10 hours synchronizedEuglena gracilis was transferred to permanent light together with application of glucose (1%) (= photoheterotrophic conditions) or to permanent light only (= autotrophic conditions). After 5, 96, 120 or 144 hours intact chloroplasts were isolated, osmotically shocked and their thylakoids degraded stepwise by addition of sodium-deoxycholate. The proteins of the resulting three membrane-fractions were separated electrophoretically. The amount of the chlorophyll-protein-complexes was determined. After 140 hours photoheterotrophic nutrition the cellular amounts of chlorophyll and protein are diminished, in comparison with autotrophic cultivation, especially the content of the chlorophyll-protein-complex CP II decreases, which is related to the light-harvesting-complex, whereas the chlorophyll-protein-complex CP I—the monomer of the reaction centers of photosystem I—is unaffected.

    Hemmung der lichtabhängigen Chloroplastenentwicklung etiolierterEuglena gracilis durch Glucose (1980)

    Notes: Summary In order to examine the inhibitory effect of heterotrophic nutrition on the regreening of etiolatedEuglena gracilis, strain Z, the organisms were cultivated in the light in the presence of glucose or carbon dioxide as carbon source. After about 120 hours of illumination the chlorophyll and carbohydrate contents per cell of the photoheterotrophically cultivatedEuglena differs significantly from that of autotrophically grown cells. Mainly in so far as the addition of glucose diminishes the number and size of the chloroplasts per cell and the amount of the chlorophyll-protein-complex CP II in the thylakoids, whereas the amount of the chlorophyll-protein-complex CP I is not influenced.
