Excessive fragmentation is the property of small oligomers where collisional energy within a smaller number of oscillators dissipates through extensive fragmentation. The procedures discussed in this report are unified into a singular strategy using an ion trap mass spectrometer with the sensitivity expected for electron multiplier detection. Although a small set of structures have been discussed, the
Characterization of Properties and Transglycosylation Abilities of Recombinant α-Galactosidase from Cold-Adapted Marine Bacterium Pseudoalteromonas KMM 701 and Its C494N and D451A Mutants
(α-PsGal) from the cold-adapted marine bacterium Pseudoalteromonas sp. KMM 701, and its mutants D451A and C494N, were studied in terms of their structural, physicochemical, and catalytic properties. Homology models of the three-dimensional α-PsGal structure, its activecenter, and complexes with D-galactose were constructed for identification of functionally important amino acid residues in the active site
Compositions for therapeutic or diagnostic use in connection with bacterial infections containing as an active constituent the structural element, preferably in terminal position:
A process for the therapeutic treatment of mammals including man, comprising administering to the mammal an active amount of such a composition. A process for identification or quantification of such structural element in native biological ma'arial from mammals including man, comprising using antibodies, the generation of which has been initiated by such composition. A process for the identification of bacterial acceptor structures (pili, syn. fimbriae) recognizing the described structural element, comprising using this recognition. A process for purifying acceptor structures of bacteria, comprising using for the purification the affinity between such structural element and the corresponding acceptor structures on the bacteria. A method of diagnosing mammals including man in regard to proneness to bacterial infection involving such receptor structure, comprising generating anti- bodies against said receptor structure and recording the reaction of said antibodies and cells from the mammal.

Die Erfindung betrifft ein Präparat zur Applikation von Wirkstoffen in Form kleinster, insbesondere mit einer membranartigen Hülle aus einer oder wenigen Lagen amphiphiler Moleküle bzw. mit einer amphiphilen Trägersubstanz versehenen Flüssigkeitströpfchen, insbesondere zum Transport des Wirkstoffes in und durch natürliche Barrieren und Konstriktionen wie Häute und dergleichen. Das Präparat weist einen Gehalt einer randaktiven Substanz auf, der bis zu 99 Mol.-% des Gehaltes dieser Substanz entspricht, durch den der Solubilisierungspunkt der Tröpfchen erreicht wird. Das Präparat eignet sich zur nichtinvasiven Verabreichung von Antidiabetica, insbesondere von Insulin. Die Erfindung betrifft außerdem ein Verfahren zur Herstellung solcher Präparate.
A nanoscale self-aggregate having a unique high order structure was obtained by preparing a nanoscale self-aggregate having an oligosaccharide in the saccharide chain.
The present invention is a nanoscale self-aggregate comprising an O-glycoside type oligolipid having a structure represented by the general formula (1) shown below.
(In the formula, G represents an oligosaccharide radical composed from two to thirty bonded monosaccharides, and R represents a hydrocarbon group containing six to twenty-five carbon atoms.) This nanoscale self-aggregate assumes the shape of micro double helical fiber shaped aggregates, micro helical disk shaped aggregates, nanoscale tubular aggregates and microfiber shaped aggregates.
