  • Publication number: 20220072045
    Abstract: Contemplated treatments and methods produce substantially increased quantities of memory T-cells and a persistent immune response by subcutaneous and/or subdermal co-administration of (1) a vector comprising a recombinant nucleic acid that encodes a cancer associated epitope, a cancer specific epitope, and/or a neoepitope, (2) an immune stimulating cytokine, and (3) a checkpoint inhibitor. Most typically, the co-administration is performed at substantially the same location, preferably within 1-21 days from each other, and the vector is an adenoviral expression vector, for example, included in a viral particle such as an AdV5 virus with a deletion of the E2b gene.

  • Patent number: 9072669
    Abstract: The preparation of Pleurotus tuber-regium polysaccharide functionalized nano-selenium hydrosol with anti-tumor activity includes the following steps: 1) at normal temperature and under normal pressure, adding a Vitamin C solution to an aqueous solution of Pleurotus tuber-regium polysaccharides, and mixing uniformly; 2) adding dropwise a selenium dioxide solution or a selenite solution to the solution while mixing uniformly; and 3) adding water to the solution to a pre-determined volume, to obtain a Pleurotus tuber-regium polysaccharide functionalized nano-selenium hydrosol when the red color of the product is no longer deepened. The polysaccharides are used to control the particle size of nano-selenium, to obtain functionalized nano-elemental selenium with high anti-tumor activity and low toxicity. The anti-tumor activity of the biologically active molecule polysaccharides and the physiological effect of nano-selenium are combined, and a synergistic anti-tumor effect is achieved.

  • Publication number: 20140135481
    Abstract: The present invention describes the preparation and use of biologically and immunologically active humanized monoclonal antibodies to Shiga toxin, a toxin associated with HC and the potentially life-threatening sequela HUS transmitted by strains of pathogenic bacteria. The present invention describes how these humanized antibodies may be used in the treatment or prevention of Shiga toxin induced diseases. One aspect of the invention is the humanized monoclonal antibody which binds Shiga toxin where the constant regions are IgG1-kappa and the variable regions are murine in origin. Yet another aspect of the invention is expression vectors and host cells transformed with such vectors which express the humanized monoclonal antibodies of the present invention.

  • Patent number: 8372958
    Abstract: The present invention encompasses monoclonal and chimeric antibodies that bind to lipoteichoic acid of Gram positive bacteria. The antibodies also bind to whole bacteria and enhance phagocytosis and killing of the bacteria in vitro and enhance protection from lethal infection in vivo. The mouse monoclonal antibody has been humanized and the resulting chimeric antibody provides a previously unknown means to diagnose, prevent and/or treat infections caused by gram positive bacteria bearing lipoteichoic acid. This invention also encompasses a peptide mimic of the lipoteichoic acid epitope binding site defined by the monoclonal antibody. This epitope or epitope peptide mimic identifies other antibodies that may bind to the lipoteichoic acid epitope. Moreover, the epitope or epitope peptide mimic provides a valuable substrate for the generation of vaccines or other therapeutics.

  • Publication number: 20110283948
    Abstract: A pet water feeder comprising a first container having a main body and a threaded neck portion, a base portion defining a reservoir and having an inlet portion and an adaptor. The adaptor comprises a first engaging portion for engaging with the threaded neck portion and a second engagement portion for engaging with the inlet portion. This pet water feeder provides a useful choice to the pet loving public and save the environment because staple water bottles, such as soft drink bottles, mineral water bottles, distilled water bottles, or a juice container, could be used with the adaptor to form a pet water feeder, thereby alleviating the need of custom made water bottles.
