摘要:
Stress is exerted to the SiC crystal in the region, in which the carriers of a SiC semiconductor device flow, to change the crystal lattice intervals of the SiC crystal. Since the degeneration of the conduction bands in the bottoms thereof is dissolved, since the inter-band scattering is prevented from causing, and since the effective electron mass is reduced due to the crystal lattice interval change, the carrier mobility in the SiC crystal is improved, the resistance of the SiC crystal is reduced and, therefore, the on-resistance of the SiC semiconductor device is reduced.
摘要:
Immunization of human antibody-producing transgenic mice, which have been created using genetic engineering techniques, with AILIM molecule as an antigen resulted in various human monoclonal antibodies capable of binding to AILIM and capable of controlling a variety of biological reactions (for example, cell proliferation, cytokine production, immune cytolysis, cell death, induction of ADCC, etc.) associated with AILIM-mediated costimulatory signal (secondary signal) transduction. Furthermore, it has been revealed that the human monoclonal antibody is effective to treat and prevent various diseases associated with AILIM-mediated costimulatory signal transduction, being capable of inhibiting the onset and/or advancement of the diseases.

5,11-dihydrodibenzo[b,e][1,4]oxazepine derivatives of the following general formulae and analogs thereof have a calcium channel-antagonistic effect and they are effective in treating and preventing intestinal diseases such as abnormal motor function of digestive tracts, particularly, irritable bowel syndrome:
摘要:
A method and system for pneumatically driving a pump for an artificial heart is disclosed which can pump blood as approximate as possible to the natural heart without increasing the capacity of any pressure tank. A compensation drive pressure which compensates for the drop of the drive pressure is additionally applied to the pump whenever the drive pressure is applied to the pump.

A method for producing a regenerative organ germ for transplantation includes using regenerative organ germ for transplantation ensuring continuity with a recipient after transplantation and facilitating transplantation procedures. A method for producing a regenerative organ germ provided with a guide for transplantation includes preparing a regenerative organ germ by closely contacting a first cell mass, which substantially consists of mesenchymal cells, and a second cell mass, which substantially consists of epithelial cells, culturing these cell masses within a support, and inserting the guide into the regenerative organ germ.

The ultrasonic-transducer mounting structure includes: a housing including: a body part which is formed into a hollow cylindrical shape and is provided at its front surface with a transmission surface allowing an ultrasonic wave to pass therethrough and is designed to accommodate an ultrasonic transducer therein; and plural connection pieces provided to a side surface of the body part; and a holder fixed to a rear surface of a bumper and designed to hold the housing such that the transmission surface of the housing is exposed via an opening of the bumper. The holder includes plural reception pieces to which the plural connection pieces are detachably coupled respectively. The plural reception pieces are fixed to the rear surface of the bumper to surround the opening.

A method for producing a regenerative hair follicle germ for transplantation, in which a color of hair that grows after transplantation is controlled, includes preparing a first cell mass containing mesenchymal cells; preparing a second cell mass containing epithelial cells; preparing a cell mass containing pigment stem cells; binding the cell mass containing the pigment stem cells to at least one among the first cell mass and the second cell mass, and closely contacting the first cell mass and the second cell mass, at least one of which has been bound to the cell mass containing the pigment stem cells, and culturing them within a support.
摘要:
A first cell mass substantially containing only either one of mesenchymal cells or epithelial cells and a second cell mass substantially containing only the other one of the cells are positioned in contact with each other inside a support carrier which can maintain a condition of cell contact; and cultured to obtain a tooth having a specific cell placement. Preferably, after the culturing, the support carrier having both cell masses is cultured with kidney cells.

摘要:
The object of the present invention is to provide a method for restoring the alveolar bone of a mammal with a missing tooth.The present invention provides a method for restoring the alveolar bone in a mammal with a missing tooth comprising a step of transplanting a regenerated tooth unit to the said missing site. The regenerated tooth unit is characterized in that it has a periodontal tissue portion in addition to a tooth crown portion.
