摘要:
It is intended to provide a regenerable cell in which a desired chromosome has been deleted, a method for producing the cell, and a gene cassette and a kit to be used for the method. More particularly, it is intended to obtain an individual corresponding pluripotent stem cell easily and simply. More specifically, it is intended to efficiently establish a cell, tissue or organ that can be a donor for treating a disease without causing immune rejection response, without newly obtaining and establishing a stem cell such as ES cell from the individual, and without using an ovum as a material. It was achieved by a gene cassette in which not two recombinase recognition sites in a cis orientation are inserted, but one recombinase recognition site or two recombinase recognition sites in an opposite orientation is/are inserted and a marker gene is connected, and by application of the gene cassette to a cell fusion technique.

In 2D photonic crystals, cavities having a heightened Q factor are made available, wherein combining the high Q cavities with waveguides affords channel add/drop filters having high resolution. In a cavity constituted by a point defect within a 2D photonic crystal, the 2D photonic crystal is configured by an arrangement, in a two-dimensional lattice of points defined in a slab (1), of low-refractive-index substances (2) having a low refractive index relative to the slab (1) and being of identical dimension and shape. The point defect (4) contains a plurality of three or more lattice points that neighbor one another, and in these lattice points no low-refractive-index substances (2) are arranged; therein the low-refractive-index substance (2) that should be arranged to correspond to at least one of the lattice points nearest the point defect (4) is arranged displaced by a predetermined distance from that lattice point.

A system of this invention includes terminals (51, 61) each of which makes a display device display a visualized image on the basis of visualized image data, and a main Web server (11) which is connected to the terminals (51, 61) via a network (1000), assigns a visualization job ID used to identify a visualization job to a visualization request from the terminal (51, 61) in response to that visualization request, manages the visualization job by associating visualized image data with the visualization job ID, displays selectable visualization jobs, visualized images of which are being displayed on any of the terminals (51, 61), on the display device of the terminal (51, 61) to prompt the user to select a desired visualization job, acquires visualized image data associated with the visualization job ID selected by the user, and controls to transmit the visualized image data to the terminal (51, 61).
摘要:
A method of the present invention, for producing an aromatic iodine compound, includes the step of causing an iodizing agent, and an aromatic compound whose nucleus has one or more substituent groups and two or more hydrogen atoms, to react with each other under the presence of a certain ether compound. This realizes such a method of producing an aromatic iodine compound that position selectivity in iodizing reaction of an aromatic compound is improved.
摘要:
A method of producing an induced pluripotent stem cell includes introducing into a somatic cell one or more non-viral expression vectors. The vectors include one or more of an Oct family gene, a Klf family gene, a Sox family gene, a Myc family gene, a Lin family gene, and Nanog gene. The somatic cell is then cultured in a medium that supports pluripotent stem cells. At least a portion of the one or more introduced non-viral expression vectors is not substantially integrated in the chromosome.
