Abstract: A method for operating magnetic body particles that is for fixing a target substance in a liquid sample to the surface of the magnetic body particles; and a device for operating magnetic body particles that is used for said method. The magnetic body particles are particles to which a target substance can be fixed selectively. In this method, in a state where a liquid sample, the magnetic body particles, and a magnetic solid body that has a larger particle diameter than that of the magnetic body particle are made to coexist in a container, the magnetic body particles are moved together with the magnetic solid body within the liquid sample by operating a magnetic field from outside the container. By this operation, the target substance can be fixed selectively to the surface of the magnetic body particles.

Abstract: Human or humanized tissues and organs suitable for transplant are disclosed herein. Gene editing of a host animal provides a niche for complementation of the missing genetic information by donor stem cells. Editing of a host genome to knock out or disrupt genes responsible for the growth and/or differentiation of a target organ and injecting that animal at an embryo stage with donor stem cells to complement the missing genetic information for the growth and development of the organ. The result is a chimeric animal in which the complemented tissue (human/humanized organ) matches the genotype and phenotype of the donor. Such organs may be made in a single generation and the stem cell may be taken or generated from the patient's own body. As disclosed herein, it is possible to do so by simultaneously editing multiple genes in a cell or embryo creating a “niche” for the complemented tissue.

Abstract: Multi-carbon compounds such as ethanol, n-butanol, sec-butanol, isobutanol, tert-butanol, fatty (or aliphatic long chain) alcohols, fatty acid methyl esters, 2,3-butanediol and the like, are important industrial commodity chemicals with a variety of applications.
