  • Publication number: 20150132285
    Abstract: The present invention provides a method of making a proteinase-engineered cancer vaccine for treating a cancer patient, especially for cancer patient at advanced/metastatic stage. The cancer vaccine comprises dead cancer cells with unbroken plasma membrane wherein the extracellular proteins and extracellular portion of membrane proteins are cleaved by proteinase digestion. The cancer vaccine may be derived from cancer cell lines or patients' cancer cells. The present invention provides a method of treating a cancer patient by administrating an effective amount of the cancer vaccine to the patient. In a clinical trial with 35 cancer patients, the cancer vaccine therapy brings cancer-free lives (no detectable tumor, micro tumor or cancer cells after treatment) back to 40% of these patients. The cancer vaccine therapy for the first time brings the promise of cure to this deadly disease.

    Abstract: Techniques are provided for allowing a user to create a document processing job (e.g., a print job, a scan job, a copy job, fax job) at a mobile device instead of at a document processing device, such as a printer, scanner, or copier. A cloud service interacts with the mobile device to retrieve job settings data from the mobile device. The cloud service generates a job identifier, associates the job identifier with job settings associated with the job settings data, and sends the job identifier to the mobile device, which displays the job identifier to the user. The user later enters the job identifier at the document processing device, which, in turn, uses the job identifier to request the job settings from the cloud service. The cloud service identifies the job settings based on the job identifier and sends the job settings to the document processing device.

  • Patent number: 8017110
    Abstract: A process for damaging and maintaining damage to the nucleic acids of pathogens such as white blood cells, bacteria and viruses which may be contained in blood or blood components. This process comprises adding to the blood or blood component containing pathogens an effective amount of riboflavin, and exposing the fluid to light of an appropriate wavelength to damage the nucleic acid of the pathogen and to substantially maintain the damage to the pathogenic nucleic acids to allow for subsequent transfusion into a recipient.

  • Patent number: 7960175
    Abstract: It is an object of the present invention to provide an immunodeficient animal capable of generating human-derived lymphoid cells, a human-derived lymphoid cell, and a method for producing a human antigen-specific antibody. The means for solving the aforementioned object is: an immature immunodeficient mammal into which human-derived hematopoietic precursor cells have been transplanted, and which is able to generate said human-derived hematopoietic cells or immunocompetent cells; and a method for producing a human-derived antibody, which is characterized in that it comprises recovering immunocompetent cells from the above-described mammal, culturing the immunocompetent cells, and collecting a human-derived antibody from the obtained culture product.

  • Publication number: 20100317054
    Abstract: The present invention relates to the cloning, identification and characterization of the unique and entire genomic sequences encoding new porcine DC-SIGN and LSECtin proteins, including the novel nucleotide sequences of the full-length cDNA and genes of both pDC-SIGN gene and pLSECtin. Also provided are the nucleic acid molecules encoding newly discovered porcine ICAM-3 isoforms from porcine monocyte-derived dendritic cells and the use thereof. Specifically, the invention is drawn to an isolated nucleic acid molecule comprising a nucleotide sequence encoding one or more of porcine DC-SIGN, porcine ICAM-3, porcine LSECtin, a complement of the nucleotide sequence or a functional, defined portion of the nucleotide sequence or a protein fusion product linked to a protein that may be of porcine or human origin.

  • Publication number: 20100278789
    Abstract: A method of increasing insulin content in adult islet beta cells is disclosed. The method comprises contacting the adult islet beta cells with an agent capable of down-regulating activity and/or expression of at least one component participating in a NOTCH pathway, the component being up-regulated in beta cell dedifferentiation above a predetermined threshold, thereby increasing the insulin content in adult islet beta cells. Methods of labeling dedifferentiated adult islet beta cells are also disclosed. Cell populations generated using the methods of the present invention and uses thereof are also disclosed.
