Electron diffraction from phospholipids – an approximate correction for dynamical scattering and tests for a correct phase determination
Autor: D. L. Dorset, J. N. Turner, M. P. McCourt, W. F. Tivol
Publikováno v: Journal of Applied Crystallography. 26:778-786
An approximate experimental correction of electron diffraction intensities from an epitaxically crystallized phospholipid bilayer for dynamical scattering is described. This correction, which is useful for certain low-angle centrosymmetric data sets,

Dynamical scattering and electron crystallography - ab initio structure analysis of copper perbromophthalocyanine
Autor: W. F. Tivol, Douglas L. Dorset, J. N. Turner
Publikováno v: Acta Crystallographica Section A Foundations of Crystallography. 48:562-568
Electron diffraction intensity data were collected at 1200 kV from thin epitaxically oriented crystals of copper perbromophthalocyanine (C32Br16CuN8) in a projection down molecular columns. Measured cell constants for the projection with cmm symmetry

Regulation of receptor-mediated shape change in astroglial cells
Autor: William Shain, A. Fiero, D. Bausback, J. N. Turner, V. Madelian
Publikováno v: Glia. 5:223-238
Activation of adenylate cyclase in astroglial cells in culture results in a rapid change in cell shape that appears to occur by the active movement of cytoplasm from peripheral cell regions to the perinuclear space with processes being formed along r

Attachment of astroglial cells to microfabricated pillar arrays of different geometries
Autor: A M, Turner, N, Dowell, S W, Turner, L, Kam, M, Isaacson, J N, Turner, H G, Craighead, W, Shain
Publikováno v: Journal of biomedical materials research. 51(3)
We studied the attachment of astroglial cells on smooth silicon and arrays of silicon pillars and wells with various widths and separations. Standard semiconductor industry photolithographic techniques were used to fabricate pillar arrays and wells i
