PROBLEMS TO BE SOLVED BY THE INVENTIONTo provide aqueous solutions of conophylline and/or conophyllidine; methods for purifying conophylline and/or conophyllidine from the aqueous solutions; methods for producing the aqueous solutions, water-soluble compositions containing conophylline and/or a conophyllidine useful for food compositions or pharmaceutical compositions or methods for preparing the same; as well as food compositions or pharmaceutical compositions containing the water-soluble compositions.MEANS OF SOLVING THE PROBLEMSIt has been found that conophylline and/or conophyllidine can be efficiently extracted from a plant producing conophylline and/or conophyllidine with an acidic aqueous solution having a pH equal to or less than 4. The extract thus obtained, i.e., aqueous solution of conophylline, and/or conophyllidine is useful for production of, for instance, food compositions, pharmaceutical compositions, etc.
Abstract:
A microscope includes a photon source which sequentially generates sets of quantum-mechanically entangled photons including at least two photons, a lens which focuses a set of photons, an actuator which varies a relative distance between a focal position of the lens and a specimen with a minute displacement, a detector detecting photons transmitted through or scattered by the specimen, and a counter counting coincidence detections of n-numbers of photons with the detector during a gating time which is set so that a rate that a number of photons detected during thereof belong to a single set of quantum-mechanically entangled photons exceeds a predetermined rate depending on the varied relative distance.
Abstract:
A beam scanning antenna has the following structure: A primary radiator and a flat wave collector are disposed between metal plates, and input and output portions are provided on one of the metal plates. In the wave collector, a plurality of strip-shaped electrodes substantially parallel to one another in the direction of travel of electromagnetic waves is disposed on one principal surface of a substrate made of a material whose dielectric constant can be changed by an electrostatic field, and on the other principal surface, an counter electrode being strip-shaped or formed on a substantially entire area of the surface is disposed so as to be opposed to the strip-shaped electrodes.
Abstract:
The present invention relates to isolated polypeptides having aminopeptidase activity and isolated nucleic acid sequences encoding the polypeptides. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the nucleic acid sequences as well as methods for producing and using the polypeptides.
Abstract:
An indole derivative represented by formula (1), ##STR1## wherein A is a group ##STR2## wherein R.sup.10 is hydrogen or lower alkyl, dotted lines may optionally be present, and R.sup.1 -R.sup.9 represents various substitutional groups. The compound (1) exhibits a positive inotropic action on cardiac muscle, an anti-arrhythmic action, and a vasodilation action without increasing the heart rate. A heart affection therapeutic agent comprising this compound as an effective component is extremely effective for treating heart failures and arrhythmia.
Abstract:
A plasmid and a DNA fragment each of which contains a gene for tetracycline resistance derived from a glutamic acid-producing coryneform bacterium, and a coryneform bacterium containing said DNA fragment. The gene for tetracycline resistance derived from a glutamic acid-producing coryneform bacterium is a useful selective marker in effecting the breeding of a glutamic acid-producing coryneform bacterium by genetic recombination. Using the plasmid, the DNA fragment or the coryneform bacterium of the present invention, breeding of the glutamic acid-producing coryneform bacterium can be easily and effectively conducted by means of recombinant DNA technique.
Abstract:
The purpose of the present invention is to provide a better intestine immunomodulator. The intestine immunomodulator of the present invention comprises bacterial cells or a bacterial component of a Lactobacillus paracasei K71 strain having an international deposit No.: FERM BP-11098 as an active ingredient. Preferably, the intestine immunomodulator is used to facilitate production of secretory immunoglobulin A or to activate natural killer cells.
Abstract:
A prescribed virtual person was created for allowing a real person (user) in the actual world to pretend to be the virtual person (virtual person) and act as the virtual person when acting on a network and registered in a database 12a of a financial institution 7 for enabling the user to make shopping or the like as the virtual person with an electronic certificate issued by the financial institution 7 for the virtual person when pretending to be the virtual person and acting on the network, and the address of the virtual person necessary as the destination of a purchased article was set to a nearby convenience store. When acting on the network as the virtual person, cookies are rendered easily acceptable as compared with the case of the real person.
