    Notes: The x-ray emission processes associated with K, L1, and L2,3 chlorine core shell ionization in the CH3Cl molecule have been studied using ab initio molecular orbital methods. The energy and absolute transition rates of XES processes have been calculated. Comparison with atomic calculations is used to identify weak molecular effects. For the Kβ spectrum relaxation terms must be included to obtain good agreement between the calculated and experimental spectra. It is concluded that three transitions are major contributors to the Kβ spectrum. However, a one-center model is adequate to account for the Kα spectrum. Uncertainty regarding the extent of satellite contribution to the experimental L2,3 spectrum and the breakdown of the single particle model has made direct comparison between theory and experiment difficult. New measurements and a more refined theoretical approach beyond the relaxed Hartree–Fock model are desirable. The L2,3 and L1 or Kβ emission spectra provide complementary information for probing the valence electronic structure of the CH3Cl molecule.

    Notes: [Auszug] Cholera, like the vegetable cathartics, evokes a profuse diarrhoea. A previous investigation4 from this laboratory suggested that the diarrhoea of cholera might be due to inhibition of active transport of Na+ ions by intestinal mucosa cells. Subsequently it was reported that such an inhibitor is ...

    Notes: [Auszug] The fluid accumulation factor (FAF) in Vibrio cholerae culture filtrates rapidly loses its effectiveness even if the filtrates are stored at 4 C.

    Notes: [Auszug] Karyotypic analysis of more than 30 retinoblastoma tumours both in our laboratory4 and by Kuznetsova et al.5 has failed to show a high frequency of abnormalities of chromosome 13; in only one case was there a somatic deletion involving the 13ql4 locus. However, Balaban et al.6 found that five of ...

    Notes: [Auszug] B lymphocytes differentiate from pluripotent stem cells in the bone marrow3-4. These cells are probably identical or closely related to haemopoietic stem cells.

    A detailed analysis of chromosomal changes in heritable and non-heritable retinoblastoma (1985)
    Springer
    Human genetics 〈Berlin〉 70 (1985), S. 291-301

    Notes: Summary Full cytogenetic analysis of 27 different retinoblastoma tumors is presented. Gross aneuploidy of chromosome arms 6p and 1q were very common, being observed in 15/27 and 21/27 tumors, respectively. However, we found that chromosome 13 was rarely missing: only 3/27 had a detectable monosomy affecting 13q14. Monosomy of chromosome 13 by small deletion or rearrangement was also not observed in any of 12 retinoblastoma tumor lines analyzed detail at the 300–400 chromosome band level. A novel observation in retinoblastoma was the discovery of non-random translocations at three specific breakpoints, 14q32 (4/12), 17p12 (5/12), and 10q25 (3/12). Genomic rearrangements similar to those described involving C-myc in Burkitt lymphoma 14q+ cells could not be demonstrated in the four 14q+ retinoblastoma lines using molecular techniques, and a probe mapping to the site implicated to have an activating role in lymphoma. These data suggest that there is a target for rearrangement at 14q32 but it is not the same sequence used in some Burkitt lymphomas. Two other breakpoints (2p24 and 8q24) coincided with the mapped position of cellular oncogenes, but also failed to show a molecular rearrangement with the oncogene probes. The breakpoints, 10q25 and 17p12, are constitutional fragile sites which may predispose these regions to act as acceptors of translocations in malignant cells. One line had double minute chromosomes, and was the only one of 16 (6%) tested with the N-myc probe which had an amplification. Different tumors from single patients with multifocal heritable retinoblastoma showed independent karyotype evolution. Unilateral non-heritable tumors exhibited a high level of karyotype stability throughout both in vivo and in vitro growth. The various common patterns of aneuploidy and translocations probably confer an early selective advantage to malignant cells, rather than induce malignant transformation.
