    Description: Chemical and mineralogical compositions of ferromanganese oxide coatings on rocks dredged from the New England Seamounts, the Sierra Leone Rise and the Mid-Atlantic Ridge near the Equator have been determined in an investigation of regional differences in Atlantic ferromanganese deposits. Most encrustations are clearly of hydrogenous origin, consisting mainly of todorokite and delta MnO2, but several recovered from the equatorial fracture zones may be hydrothermal accumulations. Differences in the chemistry of the water column and in growth rates of the ferromanganese coatings may be important in producing this regional contrast in composition. Fine-scale changes in element abundances within the encrustations indicate that the nature of the substrate has little influence on compositional variations.

    Computational study on excitation, propagation, and two-species-ion-plasma heating due to the ion-Bernstein wave (1986)

    Notes: External excitation, propagation, and ion heating for the ion-Bernstein wave (IBW) are studied for the single-ion and two-ion species plasmas, using particle simulation. It is found that the value of ω/Ωi near the antenna position influences the excitation characteristics of the IBW. The wavelength and group velocity of the propagating IBW agree well with those calculated from the linear dispersion relation. Corresponding to the experiment done with the JIPP T-II-U device [Phys. Rev. Lett. 54, 2339, (1985)], the 3ΩD heating process in the plasma composed of deuterium-like and hydrogen-like ions is investigated. The wave energy is deposited into the bulk and tail of the deuterium-like ions because of third harmonic cyclotron resonance and the bulk of the hydrogen-like ions because of 3/2 ΩH cyclotron subharmonic resonance.The possibility is also discussed that the heating efficiency may not depend on the concentration of the deuterium-like ion in the 3ΩD heating in the actual tokamak experiment.

    The adherence of Eikenella corrodens to guinea pig macrophages in the absence and presence of anti-bacterial antibodies (1987)

    Notes: The interaction of oral bacteria with host cells may play an important role in the pathogenesis of periodontal disease. The purpose of this study was to investigate the adherence mechanism of Eikenella corrodens 1073 to guinea pig peritoneal macrophages in the absence or presence of anti-bacterial antibodies. The first experiments were focused on the mechanism of E. corrodens adherence to macrophages in the absence of antibodies and complements. The adherence was dependent on time, bacterial concentration and pH. The adherence was inhibited by ethylendiaminetetraacetic acid and restored by adding calcium ions. Heating (100°C for 5 min) or protease (trypsin or pronase) treatment of bacterial cells abolished their capacity to adhere to macrophages. The specificity of E. corrodens adherence to macrophages was also proved using a hapten inhibition assay with saccharides. Among the sugars tested, the adherence was sensitive to N-acetyl-D-galactosamine (GalNAc)- and D-galactose (Gal)-containing sugars. GalNAc was the most potent inhibitor, being 10 times greater than Gal. These results suggest that the adherence of E. corrodens to macrophages in the absence of antibodies and complements may require the interaction between bacterial cell surface lectins and GalNAc-like receptors on the surface of macrophages. The second group of experiments was aimed at comparing the adherence mechanism of anti-body-nontreated E. corrodens to macrophages with that of antibody-treated E. corrodens. The adherence of antibody-treated E. corrodens reached a plateau after incubation for 10 min, whereas that of antibody-nontreated E. corrodens reached a plateau after incubation for 30 min. The adherence of antibody-nontreated E. corrodens was completly inhibited by GalNAc, whereas the adherence of antibody-treated E. corrodens was only slightly inhibited by GalNAc. Treatment of macrophages with heat aggregated IgG before incubation with antibody-treated E. corrodens caused an 80% decrease in adherence. These results show that E. corrodens adherence to GalNAc-like receptors on the macrophage surface via bacterial lectin in the absence of antibodies is quite different from the mechanism of E. corrodens adherence to Fc receptors in the presence of bacterial antibodies.

    Notes: Abstract The wavelength dependence and polarization characteristics of the infrared light scattered from an undoped GaAs crystal were investigated in the 90° angle infrared light scattering configuration. The scattering is Rayleigh scattering from scatterers which are always associated with the dislocations, and they are classified into three types,S, L A , andL G scatterers, according to their polarization characteristics. TheS, L A , andL G -scatterers are thought to be small As clusters, large As precipitates and large Ga precipitates, respectively.

    Enhanced production of γ-interferon by therapy with parenteral OK-432 and α-interferon in patients with head and neck cancer (1986)

    Notes: Summary Although the drug OK-432 can induce the release of γ-interferon (IFN-γ), the serum concentrations of IFN-γ produced are very low. We studied the effects of combining OK-432 with α-interferon (IFN-α) on the endogenous production of IFN and the postoperative courses of patients with oral cavity cancers. Forty patients operated on for head and neck cancers were studied. Each patient was given an injection of OK-432 1 week after surgery. Between 10 and 14 days later, a combination of OK-432 and IFN-α was given to assess the effects of the concomitant use of IFN-α on IFN production. In 18 of the 30 patients given a large dose of IFN-α (3 or 5×106 IU/ mg protein), IFN production induced by OK-432 was enhanced. A small dose of IFN-α (7×103 IU) did not enhance the action of OK-432. OK-432 also induced the release of both endogenous IFN-γ and IFN-α, and the production of both types of IFN was enhanced by the concomitant administration of parenteral IFN-α. Next, 50 patients operated on for oral cavity cancers were given OK-432 or a combination of OK-432 and IFN-α for 4 months, and their postoperative courses were followed for 2–5 years. The clinical courses were better in the combined therapy group than in the group given OK-432 alone.
