  • Patent number: 8351701
    Abstract: A method recognizing dice dots comprises the steps: projecting at least one dice with a plurality of different angle light sources; capturing a plurality of images of the dice according to the projecting times of the light sources on the dice; and recognizing dice dots based on the images through calculation methods. When recognized results obtained through the calculation methods are judged same by the recognizing module the dice dots are confirmed and accepted. If the recognized results done through the calculation methods are different, the dice is rolled anew.

  • Patent number: 8232373
    Abstract: The present invention relates to a composition comprising a peptide immunogen useful for the prevention and treatment of Alzheimer's Disease. More particularly, the peptide immunogen comprises a main functional/regulatory site, an N-terminal fragment of Amyloid ? (A?) peptide linked to a helper T cell epitope (Th) having multiple class II MHC binding motifs. The peptide immunogen elicits a site-directed immune response against the main functional/regulatory site of the A? peptide and generate antibodies, which are highly cross-reactive to the soluble A?1-42 peptide and the amyloid plaques formed in the brain of Alzheimer's Disease patients. The antibodies elicited being cross reactive to the soluble A?1-42 peptide, promote fibril disaggregation and inhibit fibrillar aggregation leading to immunoneutralization of the “soluble A?-derived toxins”; and being cross-reactive to the amyloid plaques, accelerate the clearance of these plaques from the brain.

  • Patent number: 7872110
    Abstract: This invention is directed to deimmunized antibodies that are useful as immunotherapeutic drugs against Human Immunodeficiency Virus (HIV) and CD4-mediated autoimmune disorders. More specifically, antibodies expressed by clones, Clone 7 containing the recombinant genes B4DIVHv1/VK1CHO#7, Clone 16 containing the recombinant genes B4DIVHv1/VK1#16, and clone 21 containing the recombinant genes B4DIVHv1/VK1#21, are derived from mouse monoclonal B4 antibody (mAb B4). The antibodies were produced by removing particular murine determinants recognized as foreign by the human immune system. These recombinant antibodies were generated by the chimerization and deimmunization of the Fv region of mouse monoclonal antibody (mAb) B4. For improved safety, the coding sequence may further be mutated to express an aglycosylated IgG1 antibody that is unable to bind complement.

  • Patent number: 7648701
    Abstract: The invention provides peptides comprising a sequence homologous to a portion of the third constant domain of the epsilon heavy chain of IgE, covalently linked to either (1) a carrier protein, or (2) a helper T cell epitope, and optionally to other immunostimulatory sequences as well. The invention provides for the use of such peptides as immunogens to elicit the production in mammals of high titer polyclonal antibodies, which are specific to a target effector site on the epsilon heavy chain of IgE. The peptides are expected to be useful in pharmaceutical compositions, to provide an immunotherapy for IgE-mediated allergic diseases.

  • Publication number: 20090264186
    Abstract: An apparatus for recognizing dice dots includes a dice cup to hold at least one dice, and a light source module and a capturing module located in the dice cup. The light source module generates a plurality of light sources to project to the dice. The capturing module captures images of the dice a number of times according to the light sources projection times to generate a plurality of image information. The image information are sent to a recognizing module which stores a plurality of calculation methods to recognize dice dots according to the image information. When recognized results obtained through the calculation methods are judged same by the recognizing module the dice dots are confirmed and accepted. If the recognized results done through the calculation methods are different, the dice is rolled anew.
