Patents by Inventor Steven D. Weitman

Steven D. Weitman has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6939686
    Abstract: A method of using Raman imaging microscopy to evaluate drug actions in living cells is disclosed. Specifically the invention describes the methods of using Raman imaging microscopy to detect drug uptake, distribution, binding, and metabolism in a single cell, and to study drug pharmacokinetics at the cellular level. The method involves measuring the Raman image of both the drug and the cell. Control images and post-treatment images of the cell were studied. Ratio images were calculated and the requisite information was obtained from a study of the intensity of the bright areas in the ratio images.
    Type: Grant
    Filed: December 31, 2003
    Date of Patent: September 6, 2005
    Assignee: Southwest Research Institute

  • Publication number: 20040018181
    Abstract: The present invention provides compositions and methods for inhibiting the proliferation of cancer cells and for the treatment of tumors with antagonists of the binding of ligands to the extracellular domain of MUC1, such binding being related to an oncogenic function of MUC1, and by compositions that downregulate the expression of MUC1.

  • Patent number: 4792449
    Abstract: This invention relates to a method for administering drugs. In particular a lipophilic drug is solubilized by a food, such as chocolate, and admixed with an oil-based carrier. The lipid soluble drug is thus conveyed to the gastrointestinal tract. Because this type of food is digested readily, the drug is absorbed as intended, and the dose is not subject to day-to-day variations.
