  • Patent number: 8106012
    Abstract: The present invention provides methods for predicting an effectiveness of apheresis therapy on patients with dilated cardiomyopathy, which include adding, for example, sera or such collected from patients to 18-day-old chicken fertile eggs and measuring the left ventricular ejection fraction of the eggs. High reproducibility was achieved by using urethane as an anesthetic agent for the chicken fertile eggs, maintaining the eggs in incubation sand at 40° C. during measurement, and using an ultrasonic probe with a frequency of 10 MHz or more. When the left ventricular ejection fraction is less than 90%, apheresis therapy is likely to be effective. Indeed, it has been clinically demonstrated that the apheresis therapy is successful when the left ventricular ejection fraction is improved to 90% or more by the therapy.

  • Publication number: 20110281351
    Abstract: Disclosed is a process for producing an artificial tissue, which comprises a step of providing a liquid flow control member and a mesh member in a flow path through which a cell culture liquid comprising at least one type of animal cells, a collagen-binding cell growth factor and an extracellular matrix component is circulated and cultured to accumulate the extracellular matrix molecule and the animal cells on the surface of the liquid flow control member at a high density, thereby forming a high-density cultured tissue, wherein the liquid flow control member and the mesh member are so arranged in the flow path that these members are in contact with each other or in proximity to each other, and wherein the mesh member is arranged on the back side of the liquid flow control member relative to the direction of the liquid flow. Also disclosed is an artificial tissue produced by the process.

  • Publication number: 20110195091
    Abstract: When ELISA antibody titer dropped in chickens intramuscularly inoculated with an oil vaccine, recombinant HA and NP antigens prepared using gene recombinant technology were orally administered in combination with synthetic oligo CpG as a mucosal adjuvant to the chickens. Even when the immune response induced with the oil vaccine was impaired, the antibody titer was re-induced by orally administering the recombinant HA and NP antigens, and synthetic CpG-ODN in combination.

  • Publication number: 20110159507
    Abstract: Disclosed is a method for detecting the drug effects of DNA methylation inhibitors that detects the drug sensitivity of gene-expressing cells to DNA methylation inhibitors based on gene expression of a transcription factor (PU. 1) and/or gene expression of metallothionein (MT) that participates in differentiation to neutrophil and monocyte lines or based on DNA methylation in the metallothionein (MT) gene promotor region. Hematopoietic tumors can be treated effectively and specifically after predicting the effects of DNA methylation inhibitors on the hematopoietic tumor cells of myelodysplastic syndrome, acute myelocytic leukemia (AML), and other hematopoietic organ diseases, so therapeutic results are improved.

  • Publication number: 20100267047
    Abstract: Since FIV-vaccinated cats produce antibodies against FIV, distinguishing them from FIV-infected cats is difficult by serological diagnostic methods using FIV and FIV-derived substances. The present invention enables tests for determining the presence or absence of a FIV vaccination history in a cat by detecting antibodies that are produced as a result of vaccination of a cat with an FIV vaccine, but not as a result of FIV infection. Using the methods of the present invention, whether an anti-FIV antibody-positive cat is infected with FIV or has been vaccinated can be conveniently distinguished.
