    Spectrin and ankyrin in brain (1983)

    Notes: Further similarity between mammalian erythrocyte spectrin and pig brain spectrin has been demonstrated by (a) formation of hybrid molecules with brain α-chains and erythrocyte β-chains and by (b) identification of an ankyrin protein in brain membranes. Hybrid spectrin molecules prepared from brain α-chains and erythrocyte β-chains were visualized by low-angle rotary shadowing as double-stranded rods (dimers) 100 nM in length. 125I-labeled brain α-chain that was hybridized with erythrocyte β-subunit acquired ability to bind to ankyrin sites on erythrocyte membranes. 125I-labeled brain α-chain bound only to β-subunits of erythrocyte and brain spectrin following transfer of these polypeptides to nitrocellulose paper from sodium dodecyl sulfate (SDS) gels. Thus brain spectrin and mammalian erythrocyte spectrin have shared functional sites involved in association of their subunits. Additional evidence for similarity of brain and erythrocyte membranes is the finding of a 210,000 Mr membrane protein in brain that cross-reacts with erythrocyte ankyrin and has a water-soluble domain of 72,000 Mr that is produced by protease digestion. The 72,000 Mr domain of brain ankyrin has been isolated by affinity chromatography on erythrocyte spectrin-Sepharose, and was demonstrated to bind directly to erythrocyte and brain spectrin. The brain 72,000 Mr fragment has distinct peptide maps from the erythrocyte 72,000 Mr ankyrin fragment and thus is not a result of erythrocyte contamination.

    The cytoskeleton of murine leukemia virus (MuLV)-infected mouse fibroblasts as observed under varying conditions of formaldehyde fixation (1983)
    New York, NY : Wiley-Blackwell

    Notes: Mouse fibroblasts chronically infected with Moloney murine leukemia virus (MuLV) were fixed using variable amounts of formaldehyde, then examined by indirect immunofluorescence light microscopy. Several antisera were employed to detect both external and internal antigens associated with the cells, eg, MuLV gp70, tubulin, vimentin, and actin. Our results indicate that the cell membranes could be partially permeabilized to IgG molecules directed against the three cytoskeletal antigens only after 3.7%, but not 1%, formaldehyde treatment. Complete permeabilization was achieved by subsequent acetone treatment of cells after 3.7% formaldehyde fixation. In such cells, normal-appearing cytoskeletal networks of microtubules and intermediate filaments were observed. Stress fibers were also seen; however, they appeared less numerous and thinner than those of uninfected mouse fibroblasts. Further, a significant amounts of F-actin fluorescence was localized in granules in the cytoplasm of infected cells. Similar observations were made using JLS-V9 mouse cells chronically infected with 334C virus, another MuLV. These results taken together suggest that subtle differences exist in the organization of actin within MuLV-infected and uninfected mouse fibroblasts.

    Tracer diffusion in methanol, 1-butanol and 1-octanol from 298 to 433 K (1983)

    Notes: Diffusion coefficients of argon, krypton, xenon, methane, carbon tetrachloride and the tetraalkyltins (methyl through butyl) were measured in methanol, 1-butanol and 1-octanol over the temperature range 298 to 433 K. With temperature-dependent solvent diameters fitted from the tracer diffusivity of one of the solutes, a rough-hard-sphere theory predicts well the observed tracer diffusivity over the solvent density range in which hard-sphere computer simulations are available. The Wilke-Chang correlation predicts diffusion coefficients in the higher alcohols with an average error of 80% and a maximum error of 200%. A correlation of the form Dμp/T = A where p and A depend on solute and solvent size is more successful giving an average error of 7% and a maximum error of 24%.

    Moving boundary problems in simple shapes solved by isotherm migration (1983)

    Notes: The Modified Isotherm Migration Method (MIMM) is developed for solving one-dimensional Stefan-type problems of multifront propagation in slabs, cylinders and spheres with a boundary condition of the third kind (radiation-type boundary condition). The method is illustrated for all three geometries with applications to the thawing of ice and to the freezing of a 50-50 dispersion of tetradecane in water, a system in which two freezing fronts propagate simultaneously.

    Serial homologies of the motor neurons of the dorsal intersegmental muscles of the cockroach, Periplaneta americana (L.) (1983)
    New York, NY : Wiley-Blackwell

    Notes: The types and locations of serially homologous motor neurons of the dorsal muscles in the cockroach Periplaneta americana remain rather constant regardless of the various adaptations of their muscles or the fusion of ganglia. However, the size and number of neurons do vary according to the development of the muscles they innervate. Neurons in four distinctive locations, two ipsisegmental and two antesegmental, innervate the dorsal longitudinal (DL) muscles in most segments. One of the ipsisegmental neurons (DLC) is common to all of the DL muscles of a segment and probably has a modulatory function. The dorsal oblique (DO) muscles of most segments have neurons in two antesegmental positions. One of these, an antesegmental, contralateral neuron, innervates both DO and DL muscles in each segment and is also probably modulatory. One neuron (DOC) of the prothoracic ganglion is the principal exception to the constancy of these serially homologous neurons. This neuron appears to be homologous to the DLC neurons of other segments but innervates the DO rather than the DL muscles.

    An optical method for investigating the microwave absorption characteristics of DNA and other biomolecules in solution (1983)
    New York, NY [u.a.] : Wiley-Blackwell
    Bioelectromagnetics 4 (1983), S. 21-42

    Topics: Biology , Physics
    Notes: Direct determination of the microwave absorption characteristics of biological molecules in solution by an optical heterodyne technique is described. A visibly transparent sample is irradiated in a spatially nonuniform manner with pulsed microwaves, and the spatial variation in temperature increase measured by detecting the phase chirp impressed on a single-frequency He—Ne laser beam passing through the heated region. Results for several liquids and solutions such as water, methanol, various saline solutions, and solutions of DNA and DNA sodium salt in water are described. Where direct comparison is possible the results agree very well with published values. A significant increase in the absorption of DNA solutions compared with pure water has been observed that is consistent with microwave absorption by the longitudinal mode of the double helix.

    Notes: Details are given of the computational method used to obtain an accurate solution of the equations describing two-dimensional natural convection in a square cavity with differentially heated side walls. Second-order, central difference approximations were used. Mesh refnement and extrapolation led to solutions for 103≤Ra≤10 6 which are believed to be accurate to better than 1 per cent at the highest Rayleigh number and down to one-tenth of that at the lowest value.
