    Notes: We have studied laser-induced-fluorescence (LIF) spectra of SiO+ produced by laser ablation of a Si wafer in oxygen ambient gas. Emission from neutral and ionic species of Si atoms and SiO molecules is also studied in the laser-induced plasma plume. The optimum oxygen pressure for the formation of molecular ions is found to be ∼120 mTorr. The rotational temperature of SiO+ ions shows rapid thermalization toward room temperature within 20 μs. © 1997 American Institute of Physics.

    Electron spin-polarized alkaline-earth ions produced by multiphoton ionization (2002)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: We propose two realistic schemes for producing electron spin-polarized alkaline-earth ions. One of the schemes is based on one-photon resonant two-photon ionization via fine structure manifolds of triplet states, while the other is based on one-photon resonant one-photon ionization. For both schemes we find that the ionization must take place from a triplet state to produce spin-polarized photoions. Photoions produced from a singlet state are always unpolarized regardless of the laser polarization and a magnetic sublevel from which ionization takes place. We carry out specific analysis for both schemes with Sr atoms, and find 85%–90% and 66% polarizations for the former and the latter schemes, respectively, if the wavelengths and polarizations of lasers are judiciously chosen. In particular, if all the produced photoions are in the ground s state, we find an exact one-to-one correspondence between the spin-polarization of photoions and ejected photoelectrons. © 2002 American Institute of Physics.

    Regional metamorphic belts of the Japanese Islands (1997)
    Oxford, UK : Blackwell Publishing Ltd
    The @island arc 6 (1997), S. 0 
    Details
    ISSN: 1440-1738

    Topics: Geosciences
    Notes: Abstract An overview of the regional metamorphic belts of Japan is given in the context of the tectonic evolution of the Japanese Islands. The Japanese Islands were situated on an active margin of the Eurasian continent or its constituent landmass before their assembly during the Phanerozoic. The Japanese Islands are composed mainly of metamorphosed and unmetamorphosed accretionary complexes, granitoids and their effusive equivalents that were formed by the Cordilleran-type orogeny. The metamorphic belts are regarded essentially as a deep-seated portion of an accretionary complex. In spite of continuous subduction of oceanic plates beneath the continents, these orogenic rocks were formed quite episodically, as evidenced by discontinuous matrix ages of the accretionary complexes and a striking concentration of isotopic ages of the granitoids. A systematic along-arc age shift of Cretaceous large-scaled granitic magmatism and regional metamorphism suggests a tectonic control such as ridge subduction, which triggered the episodic orogeny. A tectonic model based on the paired metamorphic belts, combined with the non-steady tectonic control, works well to explain this magmatism and metamorphism in a single arc-trench system as a continental margin process. However, the juxtapositional process of the paired metamorphic belts is still a problem. Two possible cases, namely transcurrent displacement and back-arc overthrusting are discussed.

    Along-arc lateral variation of Rb−Sr and K−Ar ages of Cretaceous granitic rocks in Southwest Japan (1990)
    Springer
    Contributions to mineralogy and petrology 104 (1990), S. 381-389

    Notes: Abstract Cretaceous granitic rocks were emplaced over a distance of 700 km along arc in Southwest Japan. Rb−Sr and K−Ar ages of a major group of these granitic rocks, with ilmenite series ore mineralogy, were examined. Rb−Sr whole rock ages of 92.8±4.0 Ma and Rb−Sr and K−Ar biotite ages of 80–88 Ma were obtained on one group of these granitic rocks from Kamo-Sera area of central Hiroshima Prefecture. The K−Ar ages of various minerals, combined with the Rb−Sr whole-rock age, give a smooth cooling curve, which suggests a 5 to 10 Ma time-lag between intrusion and cooling at 300° C for the Cretaceous granitic rocks. The Rb−Sr whole-rock and Rb−Sr/K−Ar biotite ages of these granitic rocks become younger eastward along the Southwest Japan arc, and the time-lag between the two systems remains constant at 5 to 10 Ma over the entire area. The along-arc age variation does not support the genetical relationship of the Cretaceous granitoids with steady-state subduction. The Cretaceous granitic province at the eastern margin of Eurasian continent was, at least partly, formed by an episodic event such as ridge subduction.

    Late ontogenetic development of adenosine A1 receptor coupling to associated G-proteins in guinea pig cerebellum but not forebrain (1990)

    Notes: Abstract The ontogenetic profile of [3H]forskolin and [3H]cyclohexyladenosine ([3H]CHA) binding sites in guinea pig forebrain and cerebellum was investigated. G-protein interactions of these binding sites were also examined by analyzing 5′-guanylylimidodiphosphate (Gpp(NH)p) interactions with [3H]CHA and [3H]forskolin binding. In forebrain, similar binding characteristics of [3H]CHA and [3H]forskolin binding are observed between the developmental stages E36 (the earliest time point studied) through to adult (P28, the latest time point studied), although transient increased binding of both ligands is observed just prior to birth. Scatchard analysis of binding isotherms reveal that this transient rise just prior to birth is due to an increase in the number of binding sites (Bmax) with little or no change in receptor affinity (Kd) In contrast, in cerebellum both [3H]CHA and [3H]forskolin binding remains at a relatively low level until just prior to birth when a dramatic increase of binding of both ligands is observed which continues to increase up to P28. Scatchard analysis of binding isotherms reveal that such changes in binding of both ligands are largely due to increases in Bmax and not Kd, although Scatchard analysis of [3H]CHA binding to cerebellar E51 membranes reveals an absence of higher affinity [3H]CHA binding sites. Gpp(NH)p did not affect [3H]forskolin binding. Gpp (NH)p displacement profiles of [3H]CHA binding reveal a maximum (adult) inhibition of [3H]CHA binding (approximately 80% displacement) at all time points (E36 through P28) in forebrain membranes, but not in cerebellar membranes. In cerebellum, displacement of [3H]CHA binding by Gpp(NH)p is much greater after birth than before birth. These results suggest that in cerebellum, but not in forebrain, postnatal coupling of adenosine A1 receptors to associated G-proteins is much more extensive than in the pre-natal period. The extent of this inferred coupling may also coincide with the ontogenetic appearance or presence of [3H]forskolin binding sites.

    Notes: Summary Human duodenal endocrine cells reactive with antibodies to cholecystokinin (CCK) 33 (10–20) and/or gastrin 34 (1–15) were studied by a combination of immunohistochemical and electron-microscopic methods. By immunohistochemistry, three types of endocrine cells were distinguished in human duodenal mucosa, i.e., those only positive for only CCK, those positive for both CCK and gastrin and those only positive for only gastrin. Ultrastructurally, the first cell type is characterized by many secretory granules with an eccentric dense core (mean diameter; 271+-74 nm). The second cell type, which was less frequent than the other two, has ultrastructural features that resemble type-I cells. The last cell type was composed of two types of cells containing small secretory granules identical to those of IG cells (mean diameter; 171+-31 nm) or large secretory granules indistinguishable from those of I cells (mean diameter; 286+-50 nm).

    Notes: Abstract A newly generated monoclonal antibody, YB-2, reacts simultaneously with Y (Fucα1→2Galβ1→4[Fucα1→3]GlcNAcβ), Leb (fucα1→2Galβ1→3[Fucα1→4]GlcNAcβ) and H type 2 (Fucα1→2Galβ1→4GlcNAcβ) antigens (Jpn J Cancer Res 1993: 84; 641-8). Since these antigens have been reported to be expressed strongly in malignant colorectal tissues, we investigated the usefulness of this antibody as an immunochemical tool for diagnosis of colorectal cancer. The rate of positive staining with YB-2 antibody in colorectal carcinoma (n=101), adenoma (n=26) and normal tissues (n=25) was 95.0, 50.0 and 12.0%, respectively. The specimens with negative staining were restricted in Dukes' A patients but 75% of Dukes' C patients were strongly positive. The intensity of positive staining with YB-2 antibody was also significantly related to the clinico-pathological features such as the depth of invasion, metastasis, histological types and tumor location. Moreover, the 5-year survival in patients whose tumors were positive with YB-2 antibody was found to be significantly low. Therefore, YB-2 antibody could be useful for immunodiagnosis and, possibly, immunotherapy of colorectal carcinoma.
