  • Publication number: 20050069491
    Abstract: Described are diagnostic and pharmaceutical compositions comprising a microorganism or cell containing a DNA sequence encoding a detectable protein or a protein capable of inducing a detectable signal, e.g. a luminescent or fluorescent protein, and, in a particular embodiment, furthermore (a) DNA sequence(s) encoding (a) protein(s) suitable for tumor therapy and/or elimination of metastatic tumors, e.g. a cytotoxic or cytostatic protein.

  • Publication number: 20050031643
    Abstract: Therapeutic methods and microorganisms therefore are provided. The microorganisms are designed to accumulate in immunoprivileged tissues and cells, such as in tumors and other proliferating tissue and in inflamed tissues, compared to other tissues, cells and organs, so that they exhibit relatively low toxicity to host organisms. The microorganisms also are designed or modified to result in leaky cell membranes of cells in which they accumulate, resulting in production of antibodies reactive against proteins and other cellular products and also permitting exploitation of proliferating tissues, particularly tumors, to produce selected proteins and other products. Methods for making tumor specific antibodies and also methods of making gene products encoded by the microorganism as well as antibodies reactive therewith are provided.

  • Publication number: 20040251425
    Abstract: A mechanical scanning stage for high speed image acquisition in a focused beam system. The mechanical scanning stage preferably is a combination of four stages. A first stage provides linear motion. A second stage, above the first stage, provides rotational positioning. A third stage above the rotational stage is moveable in a first linear direction, and the fourth stage above the third stage is positionable in a second linear direction orthogonal to the first direction. The four stages are responsive to input from a controller programmed with a polar coordinate pixel addressing method, for positioning a specimen mounted on the mechanical stage to allow an applied static focus beam to irradiate selected areas of interest, thereby imaged by collecting signals from the specimen using a polar coordinate pixel addressing method.

  • Publication number: 20030133949
    Abstract: A method for the evaluation of a material to determine whether the material is susceptible to bacterial contamination or colonization comprising providing bacteria which are modified to produce a first detectable signal, exposing the material being evaluated to the bacteria and determining whether the first signal is present determining whether the first signal is present on the material or within the material.

  • Patent number: 6310344
    Abstract: Disclosed is a wire-type corona charger having a wire electrode disposed between ground electrode plates. The wire electrode is supported by the ends of the plurality of wire electrode supporters which are so arranged that their ends have a curvature equal to arcuately-shaped upper edge of the ground electrode plates. The curvature coincides with one of the curvatures of the horizontal axis and the vertical axis of the interior surface of the panel faceplate, while the charger is pivoted along the other curvature of the faceplate. The charger can uniformly charge the photoconductive layer and improves the charging efficiency.

  • Patent number: 5724131
    Abstract: An integrated emission microscope with an emitted radiation detection system for collecting and analyzing radiation from a device under test. A semi-ellipsoidal mirror of high ellipticity directs emitted radiation from the device under test through an aperture to a radiation guide, Which transmits the radiation to spectral analyzer. The device under test may be mounted on a scanning stage. The system permits high spatial resolution selected area spectroscopic analysis, panchromatic imaging, and spectroscopic mapping of the emitted radiation from the device under test.
