Abstract: A method for determining pregnancy in a ruminant includes measuring an expression level of molecules induced in response to IFN-? in mucosal epithelial cells using a sample containing the mucosal epithelial cells, and determining pregnancy in the test ruminant animal by comparing the expression level with an expression level of the molecules in corresponding mucosal epithelial cells of a non-pregnant ruminant animal of the same species.

Abstract: A transportation device including first and second tray portions which are stacked relative to each other, first and second transportation openings included in the first and second tray portions, respectively, and a transportation path for a material which is formed between the first and second transportation openings. The first tray portion includes a first movable tray portion which can be displaced, the second tray portion includes a second movable tray portion which can be displaced. The first movable tray portion and the second movable tray portion are configured move between a tray position where the first and second movable tray portions form a tray member for transporting the material and a housing position where the tray portions form a housing configuring member by closing the first and second transportation openings which are exposed in the tray position.

Abstract: Disclosed is a method for constructing a nucleus-implanted egg, a parthenogenetic embryo and for producing a parthenogenetic mammal each having 2 haploid genome sets originating in mammalian ova, and provides methods of constructing a nucleus-implanted egg having a haploid genome set derived from primitive ovarian follicle egg (ng ovum) and a haploid genome set from MII phase (second meiosis metaphase) egg (fg ovum), a parthenogenetic embryo and a parthenogenetic mammal, including steps (1) introducing ng ovum into a nucleus-deleted deleted germinal vesicle stage (GV) egg, developing the obtained egg to MII phase by in vitro maturing and culturing to prepare a first nucleus-implanted egg, and (2) extracting MII phase chromosome from the first nucleus-implanted egg and introducing it into other fg ovum to prepare a second nucleus-implanted egg, wherein a ng or fg ovum from which an imprinted gene undergoing epigenetic modification during sperm generation is used.

Abstract: The present invention is to provide a method for constructing a nucleus-implanted egg, a parthenogenetic embryo and for producing a parthenogenetic mammal each having 2 haploid genome sets originating in mammarian ova, and provides methods of constructing a nucleus-implanted egg having a haploid genome set derived from ng ovum and a haploid genome set from fg ovum, a parthenogenetic embryo and a parthenogenetic mammal, which includes the steps of (1) introducing a primitive ovarian follicle egg (ng ovum) into a nucleus-deleted egg in a germinal vesicle stage (GV stage egg) and then developing them to MII phase (second meiosis metaphase) by in vitro maturing and culturing to prepare a first nucleus-implanted egg, and (2) extracting MII phase chromosome from said first nucleus-implanted egg and introducing it into other MII phase egg (fg ovum) to prepare a second nucleus-implanted egg, wherein ovum from which an imprinted gene that undergoes gene modification posteriori during the generation of sperm is deleted
