An apparatus for measuring skin permeable gas, which can be used to obtain clinical information by noninvasive and bloodless operations and are useful for in-home medical care and health management. The device for collecting skin permeable gas includes a cylindrical member including a spiral groove, a cover disposed on the upper surface of the cylindrical member, a gas-introducing section connected to the cover, a gas delivery section connected to the cover, and a sealing member for sealing the groove of the cylindrical member and for maintaining air contained in the groove at a predetermined temperature. After components in the air maintained at a predetermined temperature are analyzed, the sealing member is detached from the cylindrical member and the cylindrical member from which the sealing member is detached is then brought into intimate contact with skin of a subject to collect the skin permeable gas.

The hypoglycemic agent contains an organic zinc(II) complex having as a ligand a compound selected among aminoalkylpyridines, bis-optically active amino acids, bisaminoalkylcarboxylic acids, oligopeptides, oligopseudopeptides, di-substituted aminocarboxylic acids, α- and β-hydroxycarboxylic acids, vitamins, glutamine derivatives, etc.
摘要:
To provide a screening method for an apoptosis-suppressing substance or an apoptosis-promoting substance, the application of which substances to pharmaceuticals or diagnostic drugs are expected, also to provide an apoptosis-suppressing substance or an apoptosis-promoting substance, since Bcl-2 family having apoptosis-suppressing or -promoting activities is deeply involved in many diseases.To attain the above object, VDAC-liposomes, an indicator substance such as fluorescent-labeled cytochrome c or isotope-labeled sucrose etc. capable of passing through VDAC (voltage-dependent anion channel), and a subject substance are incubated, and then concentration changes in the indicator substance, inside and outside the VDAC-liposomes before and after the incubation, are detected in order to estimate presence or absence of the apoptosis-suppressing activity or -promoting activity of the subject substance.

摘要:
A negative resistance field-effect element that is a negative differential resistance field-effect element capable of achieving negative resistance at a low power supply voltage (low drain voltage) and also enabling securement of a high PVCR is formed on its InP substrate 11 having an asymmetrical V-groove whose surface on one side is a (100) plane and surface on the other side is a (011) plane with an InAlAs barrier layer (12) that has a trench (TR) one of whose opposed lateral faces is a (111) A plane and the other of which is a (331) B plane. An InGaAs quantum wire (13) that has a relatively narrow energy band gap is formed at the trench bottom surface as a high-mobility channel. An InAlAs modulation-doped layer (20) having a relatively wide energy band gap is formed on the quantum wire as a low-mobility channel. A source electrode (42) and a drain electrode (43) each in electrical continuity with the quantum wire (13) constituting the high-mobility channel through a contact layer (30) and extending in the longitudinal direction of the quantum wire (13) as spaced from each other, and a gate electrode (41) provided between the source electrode (42) and the drain electrode (43) to face the low-mobility channel (20) through an insulating layer or a Schottky junction, are provided. Owing to the foregoing configuration, a very narrow-width quantum wire whose lateral confinement size can, without restriction by the lithographic technology limit, be made 100 nm or less is usable as a high-mobility channel, whereby there can be obtained a negative resistance field-effect element that develops a negative characteristic at a low power supply voltage and enables securement of a high PVCR.
摘要:
An anilide is reacted with an acylating agent by using as a catalyst a tri(perfluoroalkane sulfonate) compound of any of the elements belonging to groups 3 to 5 and groups 13 to 15 in periods 4 to 6 of the periodic table, thereby bonding an acyl group to the benzene ring. Thus, ketoaniline derivatives, which are useful as physiologically active compounds or intermediates in synthesizing the same, are synthesized in high reaction yield by catalytic acylation.

摘要:
An electrode plate of a sample plate is set on the body of an electrophoretic apparatus, while a plug is inserted into a migration high voltage line connection hole and connected to a high-tension distribution cable. Each well of a base plate is inserted into a through hole of a well guide and further press-fit and engaged into a cavity of an electrode plate, for fixing the base plate to the electrode plate. Thereafter a sample is introduced into each well of the base plate and an end of a capillary column is dipped into each well for applying a migration voltage and electrophoretically injecting the sample into the capillary column.
