  • Publication number: 20230241180
    Abstract: There is provided a nucleic acid molecule comprising a nucleotide sequence encoding for a functional factor VIII protein, wherein the portion of the nucleotide sequence encoding for the B domain of the factor VIII protein is between 90 and 111 nucleotides in length and encodes for an amino acid sequence comprising a sequence having at least 85% identity to SEQ ID NO: 4 and which comprises six asparagine residues. Also provided is a functional factor VIII protein, a vector comprising the above nucleic acid molecule, a host cell, a transgenic animal, a method of treating haemophilia, e.g. haemophilia A, and a method for the preparation of a parvoviral gene delivery vector.

  • Patent number: 11406690
    Abstract: The present disclosure provides methods of generating multiplexed genetically modified animals, for example, porcine endogenous retrovirus (PERV)-inactivated pigs. The disclosure also provides methods of improving the birth rate of multiplexed genetically modified animals. In some embodiments, the present closure is concerned with the generation and utilization of porcine cells in which porcine endogenous retroviral (PERV) elements have been inactivated. In sonic embodiments, the PERV-free or PERV-reduced porcine cells are cloned to produce porcine embryos. In some embodiments, the PERV-free or PERV-reduced embryos may be grown into adult swine from which organs and/or tissues may be extracted and used for such purposes as xenotransplantation into non-porcine animals such as humans.

  • Publication number: 20100212748
    Abstract: Systems and methods are provided for detecting and preventing fluid leaks. A rate of flow of a portion of fluid flowing through a fluid distribution network over a period of time is monitored. A determination is made whether the rate of flow of the fluid over the period of time is greater than zero but so low that it indicates a leak in the water pipe. If the rate of flow over the period of time indicates a leak, then the flow of the liquid through the system is stopped and an indication is provided that a leak has been detected.
