Abstract:
A process for efficiently producing a polysaccharide from coffee beans or/and a coffee extraction residue. Use of these has not received attention because of difficulty in decomposing these. The process, which is for producing a polysaccharide from coffee beans or/and a coffee extraction residue, comprises: a step (a) in which the coffee beans or/and coffee extraction residue are reduced to particles having a diameter of 10.0 µm to 5.0 mm; a step (b1) in which after the step (a), the particles are heated at 50-100°C in the presence of a dilute alkali; a step (c1) in which after completion of the step (b1), cellulase is caused to act thereon; a step (b2) in which after the step (c1), a heat treatment is conducted at 120°C or higher in the presence of a dilute alkali; and a step (c2) in which after the step (b2), cellulase is caused to act thereon.
Abstract:
CD166 is a cell adhesion molecule belonging to an immunoglobulin superfamily that is expressed in an excessive amount on the tumor surface. If an monoclonal antibody specifically binding to the CD166 is obtained, it becomes possible to suppress growth of tumor cells, detect the cells, and supply a therapeutic drug thereto specifically. However, because the CD166 proteins are very similar to each other among mammals, it was not possible to obtain an antibody to human CD166, by immunizing, for example, mice with the human CD166. The antibody was prepared by immunizing mice with a purified avian CD 166 protein. The antibody was found to be adsorbed on human and mouse CD166 proteins in vitro as well as in vivo and to have an action to suppress tumor growth in mice.
Abstract:
An aggregate of carbon-based fine structures in which a plurality of carbon-based fine structures are collected, wherein respective carbon-based fine structures are oriented in the same direction. The above aggregate of carbon-based fine structures is an aggregate of a plurality of carbon-based fine structures in a state they are pulled by one another with strong interaction, and has such a length that allows the improvement of the handeability and workability thereof.
Abstract:
An objective of the present invention is to provide the cytolethal distending toxin (CDT) of C . hyointestinalis and polynucleotides encoding it, and novel methods for detection of C . hyointestinalis using the cdt genes. The present inventors focused on the cytolethal distending toxin (CDT) of Campylobacter bacteria, and detected the cdt genes of a Campylobacter -like bacterium isolated from an enteritis patient in Thailand. The present inventors discovered a bacterial strain whose cdtB gene was amplified by common primers in C. jejuni , C. coli, and C . fetus, but not by multiplex PCR that can specifically detect the cdtA , cdtB , and cdtC genes of the three bacterial species. The bacterial strain was identified as C . hyointestinalis by 16S rRNA gene analysis. Furthermore, the entire nucleotide sequence of the cdt genes was determined by genome walking upstream and downstream of the cdtB gene.

Abstract:
The present invention provides an organometallic complex having a high quantum efficiency even in a polymer thin film as a emitting material for organic electroluminescent (EL) element. The present invention relates to an organoiridium complex for an organic electroluminescent element represented by the following Formula; wherein a C-N ligand including two atomic groups (A 1 , A 2 ), and a β-diketone) ligand in line symmetry having two tert-butyl-substituted phenyl groups are coordinated with an iridium atom. The organoiridium complex of the present invention has a high quantum efficiency even in a polymer thin film with respect to green to yellow electroluminescence.
(In the aforementioned Formula, R 1 , R 2 , and R 3 are each a tert-butyl group or a hydrogen atom, and have at least one tert-butyl group; they may bond each other to thereby form a saturated hydrocarbon ring, when having two tert-butyl groups; A 1 , A 2 are each an unsaturated hydrocarbon ring, at least one is a single ring, and at least one is a heterocyclic ring.)
