    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.

    Notes: Abstract The penicillin-binding proteins (PBPs) of Mycobacterium smegmatis were studied. Five PBPs ranging in Mr from approx. 114000 to 25000 were detected in the cytoplasmic membrane. The affinities of the PBPs for selected β-lactam antibiotics were determined. Most of the antibiotics bound to PBPs 3 and 4 at low concentrations. A penicillin-susceptible mutant and a cefmetazole-resistant mutant were isolated by selection in vitro. The PBPs of these mutants were identical to those of the parent strain. The affinity of cefmetazole for the individual PBPs was identical in each mutant.

    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.

    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 Mikrogrammengen Fe, Co, Cu und Zn können in wäßrigen Lösungen an Zinn(IV)hydroxidniederschlägen bei pH 4–8 zu mehr als 95% angereichert werden. Sn kann als Bromid leicht abgedampft werden. Dieses Trennverfahren wurde zur emissionsspektrographischen Bestimmung geringer ppm-Verunreinigungen in hochgereinigtem Magnesiummetall angewendet.
    Notes: Summary Microgram quantities of iron, cobalt, copper, and zinc in aqueous solutions can be collected on tin(IV) hydroxide precipitates in greater than 95% yields over the range of pH 4 to 8. Tin is easily removed by evaporation as bromide. This separation technique has been applied to the emission spectrographic determination of low ppm level impurities in high-purity magnesium metal.

    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.
