    Notes: Abstract Mouse monoclonal antibody (mAb) Pgf-II specific for a 72-kDa major cell-surface protein (72K-CSP) derived from Porphyromonas gingivalis OMZ 409 was prepared. Immunoblotting analysis revealed that mAb Pgf-II reacted with 72K-CSP but not with 41-kDa fimbrial subunit protein (41K-fimbrilin) derived from P. gingivalis 381. Electron microscopic observation revealed that P. gingivalis OMZ 409 possessed peritrichous, thin fimbriae on their surface. Immunogold electron microscopy also demonstrated that mAb Pgf-II bound to the 72K-CSP examined with the gold particles arranged along the fibril array originating from the cell surface of the bacteria. These findings suggested that P. gingivalis 72K-CSP was identifiable as another fimbriae (termed Pg-II fimbriae) different from the fimbriae (termed Pg-I fimbriae) composed of a 41K-fimbrilin. Using multipin peptide synthesis technology, 102 sequential overlapping peptides covering the entire 514 amino-acid stretch of Pg-II fimbriae were synthesised. Seven immunodominant regions within Pg-II fimbrial protein molecule, which definitely reacted with the serum of patients with periodontal diseases, were detected.

    Evaluation of three individual glucosyltransferases produced by Streptococcus mutans using monoclonal antibodies (1996)

    Notes: Abstract We previously established murine hybridomas producing a monoclonal antibody monospecific against three glucosyl-transferases (I, SI and S) of Streptococcus mutans which contribute to dental caries formation. Here, we developed a new immunochemical technique (cross-dot system) with which individual levels of glucosyltransferases expressed by S. mutans can be evaluated. We also examined glucosyltransferase production and in vitro artificial plaque formation by a reference strain and several clinical isolates of S. mutans. The findings indicate that the levels of glucosyltransferases produced greatly vary with the cells and the culture medium, and that the cells producing high levels of both glucosyltransferase-SI and glucosyltransferase-I enzymes may possess high in vitro artificial plaque forming ability. We suggest that the cross-dot system will be useful for estimating the cariogenic potential of S. mutans isolates.

    Substrate-assisted laser patterning of indium tin oxide thin films (1999)
    Springer
    Applied physics 69 (1999), S. S875

    Notes: Abstract. Maskless laser patterning of indium tin oxide (ITO) thin films was studied by the use of a diode-pumped Q-switched Nd:YLF laser. The ITO films were sputter-deposited either on lime glass, the standard substrate material for flat panel display applications, or fused quartz so that the efficiency of laser patterning as a function of substrate absorption could be studied. The laser wavelength was varied among infrared (λ=1047 nm), visible (λ=523 nm), and ultraviolet (λ=349 nm and λ=262 nm). It is observed that strong light absorption by the substrate is a crucial requirement for a residue-free patterning of the ITO film. Observations and numerical calculations of the laser-induced surface temperature indicate that material removal occurs via thermal vaporization and that other mechanisms such as photochemical decomposition or spallation can be neglected.

    Description / Table of Contents: Zusammenfassung Ein Versuch zur automatischen Strukturaufklärung organischer Verbindungen durch kernmagnetische Resonanz wurde in folgender Weise unternommen: Zunächst wurden Teilstrukturen ausgewählt, die sich zum Aufbau einer Molekülstruktur eignen. Ein an das Kernresonanzspektrometer angeschlossener Computer liefert die Information über Art und Anzahl der Teilstrukturen. Auf der Grundlage dieser Teilstrukturen und der Molekülformel liefert ein Struktur-Aufbauprogramm die Molekülstruktur. Für 24 nach diesem Verfahren geprüfte, bekannte Verbindungen wurde in 9 Fällen ein eindeutig korrektes Ergebnis erhalten; in 15 Fällen lieferte der Computer mehrere Antworten, darunter auch die jeweils richtige.
    Notes: Summary An attempt to the automated structure elucidation of organic compound was made chiefly by use of NMR as follows: Partial structures which are suitable to construct a molecular structure are selected beforehand. Spectral information afforded by the computer tied into NMR spectrometer designates the number and kind of the partial structures. Then structure building up program constructs the molecular structure(s) based on these designated partial structures and molecular formula. In 24 known compounds examined by this method, one correct structure was given for 9 compounds, and multiple number of answers including an appropriate structure were given for 15 compounds.

    Nitrogen content in feces and the diet of Sika deer on the Boso Peninsula, central Japan (1999)
    Springer
    Ecological research 14 (1999), S. 249-253

    ISSN: 1440-1703
    Keywords: Cervus nippon ; density-dependent limitation ; fecal nitrogen ; rumen nitrogen ; seasonal fluctuation

    Topics: Biology
    Notes: Fecal and rumen nitrogen content of Sika deer (Cervus nippon Temminck 1838) on the Boso Peninsula, central Japan, were analyzed concerning their seasonal fluctuations and local differences at four areas on the Boso Peninsula. The mean fecal nitrogen was high in August and low in February in all the areas. The seasonal variation, however, was relatively small. This may be the result of the following reasons: the Boso deer feed on evergreen broad-leaves containing a high and stable nitrogen content in winter; little snow falls there; and the deer consume foods relatively low in nitrogen in summer. The fecal and rumen nitrogen content in both summer and winter depended on deer density.

    Keywords: distribution constant ; DSC ; powder compact ; Rosin-Rammler particle size distribution ; thermal resistance
    Source: Springer Online Journal Archives 1860-2000

    Notes: Abstract How a DSC result is influenced by the particle size distribution of a powder sample is shown, and a simple and optimal method to be included in a routine DSC analysis (e.g., purity determination) to improve the reliability of the analysis is proposed. In case ofα-Al2O3 powder, most reliable heat capacity data can be obtained by preparing a powder with a self-similar particle size distribution with a distribution constant of 0.7, and by compressing it under a pressure of 1.5 MPa for a duration of 5 min or longer.

    DSC of etched aluminum foils for use in electrolytic capacitors (1997)
    Springer
    Journal of thermal analysis and calorimetry 49 (1997), S. 1305-1314 
    Details
    ISSN: 1572-8943
    Keywords: DSC ; electrolytic capacitors ; etched Al foils ; thermal resistance ; transient state
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract A DSC method for evaluating the surface area of etched Al foils for use in high performance electrolytic capacitors is presented. A linear relationship between the etching degree (effective surface area) and the thermal resistance of the sample is obtained by means of DSC, based on the transient phenomenon. This method using the transient state in DSC measurement is not only novel, but also rapid and simple in evaluating the surface area of an etched aluminum foil. The method is effective even when the Al foil has a naturally oxidized surface.

    Topics: Chemistry and Pharmacology
    Notes: Abstract The previously described method involving the use of transient DSC was applied to pharmaceutical powder compacts and to ceramic powder compacts. The samples were prepared by compressing powders of pentaerythritol tetraacetate and two kinds of alumina powder (differing in particle size distribution) up to a pressure of 20 MPa by using a jig. For pentaerythritol tetraacetate, a linear relationship was obtained between the parameter obtained by DSC and the compaction pressure.
