    Monostotische kraniale Form bei einem Fall von Plasmozytose (1974)
    Springer
    Acta neurochirurgica 30 (1974), S. 309-318 
    Details

    Description / Table of Contents: Summary A case of solitary cranial plasmacytoma is described and a short review is provided concerning comparable cases in the literature. In the author's opinion the absence of pathological x-ray and laboratory findings does not suffice over a long period of time to prove the existence of a true solitary plasmacytoma. The authors have considered the possibility of using isotope diagnosis in addition. Furthermore abdominal plasmacytoma must be excluded. In the author's opinion the diagnosis of a true solitary plasmacytoma depends first and foremost, on a follow-up of at least 5 years without any signs of the development of a new focus or of biochemical changes. The prognosis of the monostotic form of plasmacytoma of the skull is favourable after extirpation and/or radiation therapy.
    Notes: Zusammenfassung Es wird ein Fall von solitärer kranialer Plasmozytose beschrieben und eine kurze Übersicht über vergleichbare Fälle der Literatur gegeben. Nach Ansicht der Autoren genügt das Fehlen von röntgenologischen und labormäßigen pathologischen Befunden nicht, um langfristig die Existenz eines echten solitären Plasmozytoms zu beweisen. Es wird deshalb gefordert, zusätzlich von den Möglichkeiten der Isotopendiagnostik Gebrauch zu machen. Außerdem müssen Weichteilplasmozytome ausgeschlossen werden. Erst eine Nachkontrolle von wenigstens 5 Jahren ohne Nachweis neuer Herdbildungen und biochemischer Veränderungen spricht nach Ansicht der Verfasser für ein wirklich solitäres Plasmozytom. Die Prognose der monostotischen Form des Plasmozytoms des Schädels ist nach Exstirpation und/oder Bestrahlung günstig.

    Etudes des sélénophènes mono et bisubstitués par Résonance Magnétique de 1H et de 13C (1974)

    Description / Table of Contents: Proton and carbon magnetic resonance spectra of mono-and disubstituted selenophenes are investigated. The proton chemical shifts are discussed in terms of magnetic anisotropy and electric field effects of the substituents, with a view to studying the conformational equilibrium of the carbonyl group. π Electronic charges, computed by the PPP method, are correlated with the proton and carbon chemical shifts. The coupling constants between 13C and 1H (1, 2 or 3 bonds) and 13C—77Se are shown to be good structural parameters and a set of substituent additivity constants is calculated.
    Notes: Une série de sélénophènes mono- et bisubstitués est étudiée en résonance de 1H et 13C. Les déplacements chimiques protoniques sont analysés en termes d'effets d'anisotropie et de champ électrique des substituants et utilisés à une discussion des équilibres conformationnels. Les relations entre δ1H et δ13C et les charges π calculées par la méthode PPP sont examinées. Les couplages 1J(13C—H), nJ(13C ∼ H) et 1J(13C—77Se) se révèlent de bonnes caractéristiques structurales et des relations d'additivité sont dégagées pour δ13C.

    Crystallite structure of cellulose (1974)
    New York : Wiley-Blackwell
    Journal of Polymer Science: Polymer Chemistry Edition 12 (1974), S. 1349-1374

    Notes: The crystallite structure of cellulose has been elucidated through analyses of the degradations of model compounds by gel-permeation chromatography. These compounds include single crystals of cellulose triacetate, regenerated cellulose from single crystals, precipitated celluloses from solutions, and commercial regenerated cellulose. The corresponding distribution profiles are found to follow the Keller transformation, which is a characteristic behavior of the folded crystals of synthetic polymers. It is also found that the leveling-off DP of cellulose is a first-order approximation of the corresponding fold length. A detailed folding chain model for the regenerated cellulose was constructed, and the various aspects of the structure are discussed. The kinetic data and the degradation products of native celluloses were also analyzed and found to obey the ruling of the chain fold model but not the conventional fringe-micellar model. In addition, an iodine-staining experiment pinpoints a minimum of 1.5% of true amorphous material; this is in quantitative agreement with the conformation analysis for the six-fold helical β-loop bonds. It is therefore suggested that the same chain-fold conformation is applicable to the native polymer. The hydrolysis of cellulose is found to be composed of a triple mode of degradation, i.e., a first-order random scission at the folds, a zero-order peeling reaction at the ends of the crystallites, and a first-order random scission on the lateral surfaces of the cellulose.
