    Notes: Summary An analysis of nerve growth factor (NGF) receptor expression and density in human sural nerve biopsies was performed by immunocytochemistry with a murine monoclonal antibody against the human NGF receptor. Quantitative assessment of immunostaining density was made by histospectrophotometry on frozen sections. Although there was enhanced expression of NGF receptor within endoneurium in all patients with clinical neuropathies, expression was highest in nerves with axonal disease, consistent with the proposal that disruption of axon-Schwann cell interactions triggers the reexpression of the NGF receptor. These results with human nerves, together with previous studies with animal models, suggest that NGF and NGF receptor play important roles in the general response to neuronal injury.

    Retention of catechols in capillary electrophoresis with micellar and mixed micellar solutions (1989)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: Zone electrophoresis in capillaries filled with micellar and mixed micellar solutions was examined for the separation of borate-complexed catechols. The mechanism for solute velocity was shown to involve both retention by hydrophobic interaction with the micelles and electrophoretic mobility. Mixed micellar systems involving SDS and SOS surfactants were shown to allow greater selectivity and increased separation efficiency.

    Cross sections and spin polarizations of electrons elastically scattered from oriented molecules (CH3I) (1989)
    Springer

    Notes: Abstract Elastic differential cross sections and spin polarizations for electrons elastically scattered from CH3I are calculated using the independent atom model. Three molecular orientations with respect to the incident electron wavevector are considered — first, the molecule is oriented randomly, second, the electron wave front and molecular bond are parallel, and third, the wavefront and the bond axis are perpendicular. It will be seen to what extent orientational averaging weakens features of the cross section and spin polarization. The calculations show that cross section and spin polarization measurements are a possible tool for determining the degree of molecular orientation. There is no degeneracy betweenI–C andC–I in cross section and spin polarization measurements. The results presented here for 200 eV and 600 eV electrons scattered by CH3I should be considered as a case study and it should be possible to find molecules and electron energies for which even more dramatic differences between the various orientations between the molecules and the electrons can be expected.
