    Crystal structure of the TSP-1 type 1 repeats: a novel layered fold and its biological implication

    por Hu, Ke, Roos, David S., Murray, John M.
    Publicado 2002
    “…The conoid is a 380-nm diameter motile organelle, consisting of fibers wound into a spiral like a compressed spring. FRAP analysis of transgenic T. gondii expressing YFP-α-tubulin reveals that the conoid fibers are assembled by rapid incorporation of tubulin subunits during early, but not late, stages of cell division. …”

    por Dennison, David S.
    Publicado 1965
    “…It is shown that this component is due to a rotation between the stimulus and response loci about the axis of the growing zone, which is probably related to the spiral growth of the cell. The steady-state bending speed is at a maximum value for illumination directions ranging from normal incidence to about 45°. …”

    por Maturana, Humberto R.
    Publicado 1960
    “…However, the mode of ending of the myelin layers at the nodes of Ranvier and the spiral disposition of the myelin layers indicate that myelination of these fibers occurs by a process similar to that of peripheral nerves. …”

    The Fine Anatomy of the Optic Nerve of Anurans—An Electron Microscope Study
  7. 2367
    “…This method is applied to reconstruct images of a numerical phantom as well as magnetic resonance images from experimental spiral imaging data. The results support the theory and demonstrate that the computational load of this method is similar to that of standard gridding, illustrating its practical utility.…”

    Improving Non-Cartesian MRI Reconstruction through Discontinuity Subtraction
  9. 2369
    “…Individual arcs are designed independently and do not fit together in the way that multishot spiral, radial or echo-planar trajectories do. Previously, it was shown that second-order cone optimization problems can be defined for each arc independent of the others, that nulling of zeroth and higher moments can be encoded as constraints, and that individual arcs can be optimized in seconds. …”
