The invention encompasses methods for increasing genetic progress in livestock, and for genetic dissemination, including the use of amniocentesis to obtain fetal amniocytes for use in genomic evaluation and cloning.

The present invention provides a preparation method for an anti-porcine reproductive and respiratory syndrome cloned pig, comprising: transferring CRISPR/Cas9 targeting vectors and CD163 gene homologous recombination modification vectors into fibroblasts of a pig to obtain positive clone cells, a seventh exon of porcine endogenous CD163 gene being replaced with a eleventh exon of human CD163-L1 gene, so that the positive clone cells are incapable of mediating invasions of PRRSV; taking the positive cell as nuclear transfer donor cells and oocytes as nuclear transfer recipient cells to obtain a cloned embryo by adopting a somatic cell nuclear transfer technology; and impregenating a pig by transferring the cloned embryo into the uterus of the pig, to obtain a cloned pig.

The invention provides methods for reprogramming somatic cells to generate multipotent or pluripotent cells. Such methods are useful for a variety of purposes, including treating or preventing a medical condition in an individual. The invention further provides methods for identifying an agent that reprograms somatic cells to a less differentiated state.

The disclosure relates to a method of reprogramming one or more somatic cells, e.g., partially differentiated or fully/terminally differentiated somatic cells, to a less differentiated state, e.g., a pluripotent or multipotent state. In further embodiments the invention also relates to reprogrammed somatic cells produced by methods of the invention, to uses of said cells, and to methods for identifying agents useful for reprogramming somatic cells.

Apicomplexan parasites or red blood cells infected with apicomplexan parasites are administered to an animal in combination with a delayed death agent that initially allows parasite replication but subsequently kills the apicomplexan parasites. This allows the elicitation of an immune response by the animal while preventing the parasites producing a serious infection of the animal. The apicomplexan parasites may be malaria or babesia parasites. The delayed death agent may be a tetracycline class antibiotic, a macrolide antibiotic or a lincosamide antibiotic.

An organ for transplantation having a kidney, a ureter, and a urinary bladder and an organ structure in which a first ureter, a first urinary bladder, a second ureter and a second urinary bladder are sequentially connected to a kidney can produce urine and excrete the produced urine, and thus is useful for transplantation.

The invention encompasses methods for increasing genetic progress in livestock, and for genetic dissemination, including the use of amniocentesis to obtain fetal amniocytes for use in genomic evaluation and cloning.

The object of the present invention is to provide a test method using a novel administration method of an extract from inflamed tissues inoculated with vaccinia virus or a preparation containing the extract. It has been demonstrated that by sustainedly administering an extract from inflamed tissues inoculated with vaccinia virus or a preparation containing the extract by using a continuous administration device according to the present invention, a comparable effect is exerted at a very low dose compared with conventional administration methods such as oral administration. Therefore, the present invention can provide a test method using animals requiring less burden on a researcher, a treatment of patient at a low dose, and the like.

The present invention relates to expression cassettes and vectors comprising Alzheimer's disease-related genes and a cell line transformed by the disclosed expression cassettes and vectors, and more specifically, the expression cassettes according to the present invention comprise amyloid precursor protein (APP), Tau protein, and presenilin-1 (PS1) genes associated with Alzheimer's disease so that mutant genes thereof can be simultaneously expressed. Additionally, the present invention relates to a cell line transformed by the disclosed expression cassettes or vectors comprising APP, Tau protein, and PS1 genes, and further, to an animal model transformed by the vectors or cell line.

A marker for predicting pressure ulcer development, selected from the group consisting of interleukin (IL)-1, vascular endothelial growth factor (VEGF)-C, plasminogen activator inhibitor (PAI)-1, and heat-shock protein (HSP) 90.
