  • Patent number: 10603351
    Abstract: In one aspect, the invention provides methods for preferentially killing target proliferating cells in a host, such as cancer cells, by infecting host tissues with two or more strains of virus. The strains of virus may be selected to provide a synergistic and symbiotic effect, involving a contemporaneous lytic infection in the target proliferating cells. In selected embodiments, the viruses are selected so that expression of a first virulence factor in proliferating cells infected with the first virus increases the lytic effect of the second virus; and, expression of the second virulence factor in proliferating cells infected with the second virus increases the lytic effect of the first virus. The genomes of the first and second viruses may be selected so that they are incompatible for recombination between the viral genomes in cells of the host.

  • Publication number: 20140052480
    Abstract: An insurance claim report generating system includes an interactive voice response (IVR) system, a voice recognition server, and a voice activated database (VAD) device. The IVR system receives telephone calls from remote devices, delivers audio scripts having prompts directed by both templates and data received from the remote devices. The IVR system receives dual-tone, multi-frequency (DTMF) information and human voice information in response to the prompts. The voice recognition server generates text from the human voice information using a dictionary of insurance relevant terms. The VAD device receives first digital information from the IVR system and second digital information from the voice recognition server. The first digital information is derived from the DTMF information, and the second digital information is derived from the human voice information. The VAD device generates an insurance claim report from at least some of the first or second digital information.

  • Patent number: 8282917
    Abstract: The present invention provides mutant viruses with a decreased ability to block nuclear transport of mRNA or protein in an infected cell which are attenuated in vivo. The mutant viruses of the present invention may also be capable of triggering the anti-viral systems of normal host cells while remaining sensitive to the effects of these systems. The present invention further provides for the use of the mutant viruses in a range of applications including, but not limited to, as therapeutics for the treatment of cancer and infections, as vaccines and adjuvants, as viral vectors, and as oncolytic and cytolytic agents for the selective lysis of malignant or infected cells.

  • Patent number: 8227440
    Abstract: The present invention relates to therapeutic use of Myxoma virus. Myxomas virus can selectively infect cells that have a deficient innate anti-viral response, including cells that are not responsive to interferon and can be used to treat diseases characterized by the presence of such cells, including cancer.

  • Patent number: 8147822
    Abstract: The present invention is directed to a method of reducing the viability of a tumor cell involving administering a virus that is not a common human pathogen to the tumor cell. Preferably, the virus exhibits differential susceptibility, in that normal cells are not affected by the virus. This differential susceptibility is more pronounced in the presence of interferon. The tumor cell is characterized by having low levels, or no, PKR activity, or as being PKR?/?, STAT1?/? or both PKR?/? and STAT1?/?. The virus is selected from the group consisting of Rhabdovirus and picornavirus, and preferably is vesicular stomatitis virus (VSV) or a derivative thereof.

  • Publication number: 20110044937
    Abstract: The invention provides methods for treating tumours, such as solid tumours, in a host. The methods may involve infecting the tumour with an amount of one or more strains of oncolytic virus. The virus will generally be selected to be effective to cause a lytic infection of tumour cells within the tumour. In various embodiments, the host neutrophil response to the lytic infection may be modulated, so that during the course of the lytic infection, the host has an initial neutrophil response and a secondary neutrophil response, these two responses being different in some material respect. For example, the secondary neutrophil response may mediate a greater degree of apoptotic killing of tumour cells than does the initial neutrophil response.
