    Notizen: Abstract Pick’s disease (PD) is characterized by severe neuronal loss and gliosis in a frontotemporal lobar distribution, often associated with Pick bodies and ballooned neurons. Abnormal tau metabolism has been implicated in the pathogenesis of PD; however, the underlying mechanism of neuronal degeneration remains poorly understood. Evidence from other neurodegenerative diseases has suggested that DNA damage and apoptosis may play a major role in cellular degeneration and death. In the present study, an in situ nucleotidyl transferase assay (ISNTA) was used to identify DNA fragmentation in three cases of classical PD with Pick bodies and ballooned neurons, and two PD “variants”, one with ballooned neurons only and the other without Pick bodies or ballooned neurons. In all cases large numbers of ISNTA-positive neurons were present in anatomic regions having obvious degenerative changes (neuronal atrophy and loss, gliosis, cytoplasmic inclusions) by conventional histology. There was no clear association between neuronal DNA fragmentation and the presence of structural abnormalities such as Pick bodies or ballooned cytoplasm. ISNTA-positive glia were present in both cortex and subcortical white matter. Morphologic evidence of apoptosis was not detected in either neurons or glial cells. We suggest that DNA fragmentation in PD and probably other neurodegenerative disorders most likely specifies a population of potentially vulnerable cells in which both cell death and repair mechanisms have been activated. It is likely that only a very small number of these vulnerable cells at a given time will proceed to cell death; however, it is uncertain whether this occurs by apoptosis or some other mechanism.

    Capillary gel electrophoresis of nucleic acids in pluronic F127 copolymer liquid crystals (1999)
    Springer
    Chromatographia 49 (1999), S. S65

    ISSN: 1612-1112

    Notizen: Summary The liquid crystalline gel phases of solutions of Pluronic F127, a triblock copolymer, were recently introduced as an alternative to disordered solutions of random coil polymers as replaceable media for capillary gel electrophoresis (CGE). Pluronic F127, from BASF, is a copolymer of poly(ethylene oxide) and poly(propylene oxide) with the approximate formula (EO)106 (PO)70 (EO)106. Polymer chains aggregate into spherical micelles in aqueous solutions, with poly(propylene oxide) chains creating a hydrophobic core surrounded by brushes of hydrated poly(ethylene oxide) tails. Crowding at high concentrations promotes ordering of micelles. Solutions in the range of about 14–24 % polymer are self-supporting, gel-like cubic liquid crystals at 25–30°C, but when cooled they become low viscosity liquids that are easily loaded into capillaries. This article reviews applications of Pluronic F127 media for capillary gel electrophoresis separations of nucleic acids of several types including oligonucleotides, double stranded DNA fragments, and supercoiled plasmid DNAs.
