    Notes: Zusammenfassung Im Skelett vonKatsuwonus pelamis kommt vereinzelt ein blaugrünes Pigment vor, dessen Verteilung im Endoskelett beschrieben wird. Das Pigment kann mit saurem Methanol extrahiert und in Chloroform übergeführt werden. Die saure Methanollösung des Pigments zeigt Absorptionsmaxima bei 680–690 und 370 mµ, die Chloroformlösung bei 660 und 380 mµ. Sowohl trockene Filme des Pigments als auch die Chloroformlösung geben eine positive Gmelinsche Reaktion, und der oxydierte, in ammoniakalischem Äthanol gelöste Zinkkomplex des Pigments zeigt im ultravioletten Licht eine intensive rote Fluoreszens und Absorptionsmaxima bei 590 und 640 mµ. Das Pigment besitzt somit die Eigenschaften eines Bilitrientetrapyrrol und ähnelt weitgehend dem Biliverdin.

    Notes: [Auszug] As there appears to be little information available on the control of wheat midge, it may perhaps be worth recording the following observations. In late June it was observed that the midge population in the nursery plots of wheat at the Cereal Station, Ballinacurra, Co. Cork, was very high. ...

    Notes: Zusammenfassung Die blauen ozeanischen Cirripedien,Lepas fascicularis, speichern Karotinoide in Eiern, Eingeweiden und den meisten übrigen Geweben in den folgenden ungefähren Konzentrationen: 5:2:1 mg/100 g. In jeder Art von Gewebe ist Astaxanthin das Hauptkarotinoid, welches meist in Form des blauen Chromproteins vorliegt. Kleinere Mengen von Karotin und etwas mehr Xanthophylle kommen in den Eingeweiden, nicht aber in den reifen Eiern vor.

    Notes: Abstract The variation in yield and the dose-response for chromatid aberration types following x-irradiation of Schistocerca gregaria embryo cells is described. Marked variations in yield are found for all aberration types during the G2 and latter part of S stages of interphase. Only gaps appear to follow similar curves, other aberration types having unique patterns of response. The dose exponents for the various chromatid aberration types are similar to, but lower than, those reported for other organisms. Chromatid “breaks” appear to have a dose exponent greater than 1.0 — a fact which is in conformation with the exchange hypothesis. The chromosome radiosensitivity of this organism is similar to that reported for other organisms.

    Notes: Abstract Irradiation of embryo cells of Schistocerca gregaria in the two hours before mitotic anaphase produces a characteristic series of responses. An apparently insensitive stage is followed by the production of “stickiness” and side-arm bridges and finally by mitotic delay. Mitotic delay is complete at doses as low as 25 R. It is argued that “stickiness’ is due to a generalised physiological process and that side-arm bridges are due to a localised exchange of discrete sub-units of the chromatid. These conclusions are based upon the kinetics of appearance and dose-response and a comparison of haploid and diploid cells in a haplo-diploid mosaic embryo.

    Notes: Abstract Irradiation of Schistocerca gregaria embryo cells during the S and G2 stages of interphase produces the same general classes of chromatid aberration as have been seen in organisms, such as Vicia faba, which have been used widely in radiocytological work. In addition, however, a series of intrachange aberrations has been found which is novel. In order to account for these Revell's exchange hypothesis has been extended to include the involvement of isolocus primary lesions. The exchange-type hypothesis is preferred because it can more readily accomodate the whole spectrum of aberrations found.

    The relationship between DNA value and chromosome volume in the coleopteran genus Dermestes (1969)
    Springer
    Chromosoma 27 (1969), S. 130-144 
    Details

    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Abstract DNA values and chromosome volumes were determined for six species of the coleopteran genus Dermestes which have very similar karyotypes. Large differences in DNA value occur which give no indication of a geometric series. DNA value is approximately proportional to chromosome volume, indicating that the DNA differences lie in the chromosomes. Evidence from the variation in volume of the sex chromosomes, along with the DNA values, cannot be interpreted in terms of a chromosome model with a variable number of strands. DNA values are often at variance with the taxonomic grouping of species within the genus.
