  • Publication number: 20060287231
    Abstract: The present invention relates to therapeutic applications of kallikreins and compositions containing them for treating, preventing and/or ameliorating cancers, especially epithelial cancers, such as ovarian, breast and cervical cancer.
    Type: Application

  • Patent number: 6636623
    Abstract: A system and method for rapidly detecting cells associated with malignancy and disease using molecular marker compartmentalization includes an optical tomography (OT) or a flow optical tomography (FOT) instrument capable of producing various optical projection images (or shadowgrams) containing accurate density information from a cell or cells labeled with tagged molecular probes or stains, a computer and software to analyze and reconstruct the projection images into a multi-dimensional data set, and automated feature collection and object classifiers. The system and method are particularly useful in the early detection of cancers such as lung cancer using cells from sputum or cheek scrapings and cervical/ovarian cancer using a cervical scraping, and the system can be used to detect rare cells in specimens including blood.
    Type: Grant
    Filed: May 14, 2002
    Date of Patent: October 21, 2003
    Assignee: VisionGate, Inc.
    Inventors: Alan C. Nelson, Robert W. Webster, Chee-Wui Chu
  • Patent number: 6591003
    Abstract: Three dimensional reconstruction of an object of interest moving at a constant velocity. The object of interest is centered. The object of interest is imaged with optical point sources located at multiple projection angles around the object of interest, in cooperation with opposing time delay and integration (TDI) image sensors located at a distance from the objects of interest such that there is no focal plane within the objects of interest during imaging. Each of the TDI sensors has a line transfer rate synchronized to the constant velocity of the objects of interest.
