    The Relation of Actinium to Uranium (1923)

    Notizen: [Auszug] AT present the most likely view of the origin of the actinium series is that uranium II undergoes a dual change in which about 96 per cent, of atoms form ionium and the radium series, and the remainder form uranium Y, the product of which, proto-actinium, is the parent of the actinium series. ...

    The Isotopes of Lead (1923)
    [s.l.] : Nature Publishing Group
    Nature 112 (1923), S. 619-620

    Thema: Biologie , Chemie und Pharmazie , Medizin , Allgemeine Naturwissenschaft , Physik
    Notizen: [Auszug] IT was suggested by the writer in 1912 that the end-products of the uranium and thorium disintegration series should differ in atomic weight from that of common lead, which chemically they closely resemble. As the atomic weights of these products, determined experimentally later by Richards and ...

    A Calculation of the Atomic Weights of Isotopes (1923)
    [s.l.] : Nature Publishing Group

    Details
    ISSN: 1476-4687

    Thema: Biologie , Chemie und Pharmazie , Medizin , Allgemeine Naturwissenschaft , Physik
    Notizen: [Auszug] SOME months ago, when engaged on a study of radioactive disintegration series, the results of which appeared in the October issue of the Philosophical Magazine, I was able to formulate simple rules from radioactive data which enabled me to calculate a list of the atomic weights of the principal ...

    The absence of circulating immune complexes in patients with ankylosing spondylitis (1981)
    Springer
    Rheumatology international 1 (1981), S. 107-109 
    Details
    ISSN: 1437-160X
    Schlagwort(e): Complexes ; Ankylosing spondylitis
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Medizin
    Notizen: Summary Sera from 50 patients with well-defined ankylosing spondylitis were examined for circulating immune complexes using both a C1q binding (fluid phase) assay and a Raji cell assay. No more than five of the patients assessed had circulating immune complexes by either one of these techniques and none were positive in both. This result is in contrast to the high prevalence in sera from unselected patients with rheumatoid arthritis and systemic lupus used as positive controls.

    A comparison of patients with seropositive and seronegative rheumatoid arthritis (1983)
    Springer
    Rheumatology international 3 (1983), S. 47-48 
    Details
    ISSN: 1437-160X
    Schlagwort(e): Rheumatoid ; Clinical ; Seropositive ; Radiological ; Seronegative
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Medizin
    Notizen: Summary It has recently been suggested that a subpopulation of patients with rheumatoid arthritis, diagnosed on clinical, radiologic and pragmatic grounds, but with negative rheumatoid factor tests, represents a clinical entity quite distinct from that of seropositve rheumatoid arthritis. We have studied 60 sequentially presenting patients, 30 of whom were selected because they were seronegative, and 30 selected because they were seropositive in regard to IGM rheumatoid factor. The only major differences detected between the two groups on ‘blind’ assessment were a greater tendency to deformity, a greater degree of erosion and the presence of subcutaneous nodules in the seropositive group. Seronegative and seropositive rheumatoid arthritis appear to have very similar clinical features, but differing degrees of severity.

    Need for the Redetermination of the Atomic Weights, of Uranium, Thorium, and Radium (1924)
    [s.l.] : Nature Publishing Group
    Nature 114 (1924), S. 717-718 
    Details
    ISSN: 1476-4687
    Quelle: Nature Archives 1869 - 2009
    Thema: Biologie , Chemie und Pharmazie , Medizin , Allgemeine Naturwissenschaft , Physik
    Notizen: [Auszug] IT is known that the atomic weights of such radio-elements as have been determined experimentally agree approximately with those to be expected on radioactive theory, and also that small unexplained discrepancies appear when the actual instead of the approximate values are considered. The ...
