    Role of the MT-MTOC complex in determination of the cellular locomotory unit inDictyostelium (1985)

    Notes: Summary The microtubule inhibitors, ethyl-N-phenylcarbamate (EPC) and thiabendazole (TB), which disrupt cytoplasmic microtubules and induce giant cells inDictyostelium (Kitanishi et al. 1984), were found to induce the occurrence of multiple microtubule organizing centers (MTOCs) in these giant cells. Probing was done by indirect immunofluorescence using monoclonal anti-α-tubulin. The nuclear DNA content of the giant cells increased in parallel with an increase in the number of MTOCs, as shown by microspectrophotometory of cells stained with the fluorescent DNA stain DAPI (4′,6-diamidino-2-phenylindole). Shortly after the inhibitors were removed, the MTOCs of the giant cell formed multiple mitotic spindles or synchronously reconstituted numerous cytoplasmic MT-networks. These events apparently reflected the cell-cycle dependent activities of the MTOCs at the time the inhibitors were removed. When multiple spindles were formed, numerous cytoplasmic MT-networks became organized subsequent to the breakdown of the spindles. In either case, reconstitution of the cytoplasmic MT-networks was followed by apparently normal cytokinesis resulting in the production of many daughter cells each containing a single MT-MTOC complex. The evidence suggested the possible mechanism of the induction of multiple MTOCs, and implied that the MT-MTOC complex is significant in the cytokinesis ofDictyostelium by determining the cell locomotory unit.

    Dictyostelium MTOC: Structure and linkage to the nucleus (1985)

    Notes: Summary The microtubule organizing center (MTOC) was isolated fromDictyostelium discoideum to investigate the fine structure of the components as the first step in clarifying its molecular organization and function. The isolation protocol was designed to preserve microtubules bound to the MTOC by using indirect immunofluorescence employing anti-α-tubulin. After cell lysis with Triton X-100, the MTOCs were isolated in association with the nucleus by centrifugation in a microtubule-stabilizing buffer. The MTOC was found to be bound to the nucleus via an electron-dense fibrous structure, and this linkage could not be destroyed by KI, KCl, or sonication. We named this complex composed of microtubules, MTOC, and the anchor the MTOC-complex. Negative staining of the isolated MTOC-complex revealed that distinct vesicles decorated with 11-nm tacks were associated with microtubules radiating from the MTOC. Fine filaments, 4–5 nm wide, were also present close to the MTOC, aligned parallel to the microtubules. The three-dimensional profile of the central core of the MTOC, examined by transmission electron microscopy of serial thin sections of the isolated MTOC fraction supplemented by a microcomputer analysis, was concluded to be a matchbox-like cuboid (180 × 210 × 370 nm) of 15 layers. We propose that theDictyostelium MTOC is the structural domain of a more complicated unit composed of 1. MTOC, 2. microtubules, and 3. a firm fibrous linkage connecting the MTOC to the nucleus, with the MTOC core being a multilayered cuboid, associated with nodules and surrounded by amorphous electron-dense material including peculiar vesicles with 11 nm-tacks. The possible functions of these domains are discussed.

    Rheo-optical studies of high polymers. XVII. Time-temperature superposition of time-dependent birefringence for high-density polyethylene (1970)

    Notes: The strain-optical coefficient and relaxation modulus were simultaneously measured for high-density polyethylene at various temperatures ranging from 12 to 100°C. Not only horizontal but also vertical shifts were necessary to obtain smooth master curves by the application of time-temperature superposition. However, the relaxation modulus decreases with rising temperature while the strain-optical coefficient increases. This behavior indicates that the variation of the relaxation modulus and the strain-optical coefficient with time can not be explained by a decrease in crystallinity with rising temperature since a decrease in crystallinity usually causes a decrease in the strain-optical coefficient with time can not be explained by a decrease in crystallinity with rising temperature since a decrease in crystallinity usually causes a decrease in the strain-optical coefficient. It was emphasized that another explanation should be sought for the vertical shift in the time-temperature superposition of the time-dependence curves of the relaxation modulus and the strain-optical coefficient at various temperatures. The master curve of the strain-optical coefficient at various temperatures. The master curve of the strain-optical coefficient or the optical distribution function of relaxation times determined from it serve to distinguish the type and thermal history of the polyethylene.

    Rheo-optical studies of high polymers. XVIII. Significance of the vertical shift in the time-temperature superposition of rheo-optical and viscoelastic properties (1970)
    New York : Wiley-Blackwell
    Journal of Polymer Science Part A-2: Polymer Physics 8 (1970), S. 1211-1225

    Notes: To determine the true reason for the increase in birefringence and the decrease in relaxation modulus for high-density polyethylene with rising temperature, changes in crystalline structure as well as in thermal, viscoelastic, and rheo-optical properties with temperature were measured, by several techniques, including DSC, DLI, infrared dichroism, x-ray diffraction, and NMR. The values for degree of crystallinity obtained from the DSC fusion curve, density, and infrared absorbances coincide very well and show almost no divergence till about 80°C. The optical vertical shift factor pT can be related to the ratio of the orientation function for the crystal c axis at an arbitrary temperature to that at the references temperature, fε/fε0. The mechanical vertical shift factor bT, on the other hand, is associated with the temperature dependence of the mobile fraction, as determined by NMR measurements, but not with variations in degree of crystallinity.
