  • Patent number: 6190830
    Abstract: An imaging member, such as a negative-working printing plate, can be prepared using a hydrophilic heat-sensitive imaging layer comprised of a hydrophilic heat-sensitive, crosslinked vinyl polymer containing recurring organoonium groups. The imaging member can also include a photothermal conversion material such as carbon black or an infrared radiation absorbing dye. The heat-sensitive polymer has recurring units containing an organoammonium, organophosphonium or organosulfonium group that reacts to provide increased oleophilicity (ink receptivity) in response to heat. Heat is preferably generated by laser irradiation in the IR region of the electromagnetic spectrum. The heat-sensitive polymer is considered “switchable” in response to heat. The imaging member can be used in printing methods without the usual wet processing steps.

  • Patent number: 6190836
    Abstract: A method of repairing defects on masks includes the step of providing a coating on the mask to prevent damage to clear regions of the mask from laser ablation splatter, laser ablation caused quartz pitting, laser deposition staining, and FIB caused gallium staining. The coating is a metal, a polymer, or a carbon material. The coating is formed on clear regions of the mask as well as either over or under the light absorbing material of the mask. A coating comprising a thin copper layer significantly improves imaging with the ion beam while protecting clear regions of the mask from FIB stain. A coating formed of a photosensitive polymer is used to etch opaque defects. While wanted opaque regions adjacent an opaque defect are also etched in this etch step, these created clear defects are then repaired in a subsequent FIB deposition step while a copper coating protects adjacent clear regions from FIB stain.

  • Patent number: 6190844
    Abstract: High performance radiographic films exhibit visually adaptive contrast when imaged in radiographic imaging assemblies comprising an intensifying screen on both sides. These films have at least two silver halide emulsions (preferably tabular grains) on each side of a film support, and the emulsion closest to the film support on each side includes chemistry to control crossover. In addition, the films can be rapidly processed to provide the desired image whereby the upper scale contrast is at least 1.2 times the lower scale contrast. Thus, dense objects can be better seen at the higher densities of the radiographic image without any adverse sensitometric changes in the lower scale densities. These films have greater dynamic range that allows them to be scanned and digitized to correct for under- or over-exposure.

  • Patent number: 6190859
    Abstract: An inactivated dengue virus vaccine to immunize and protect humans against dengue fever is described. The vaccine is based on dengue viruses which have been propagated to high titers in suitable cells, purified and inactivated under conditions which destroy infectivity but preserve immunogenicity, a high level of which is demonstrated in animal models. Uses of the inactivated dengue virus for detecting antibodies to dengue and kits therefor are also described.

  • Patent number: 6190860
    Abstract: The present invention provides recombinant polypeptides derived from CMV glycoprotein gB and truncated fragments thereof which contain at least one epitope which is immunologically identifiable with one encoded by the CMV genome. The complete characterization of the gB protein, including the identity of glycoprotein gp55, permits the production of polypeptides which are useful as standards or reagents in diagnostic tests and/or as components of vaccines. This invention provides recombinant polypeptides and recombinant polynucleotides encoding these polypeptides wherein a neutralizing epitope of gB is localized within gp55.

  • Patent number: 6190862
    Abstract: This invention relates to the identification, purification and detection of a new infectious viral agent in arthropods, especially shrimps. The virus is named as WSBV (Baculovirus associated with white spot syndrome). Two WSBV genomic DNA libraries were constructed and based upon the sequence of one of the cloned WSBV DNA fragments, a WSBV specific primer set for PCR to detect the WSBV infection in penaeid shrimps has been developed. The results of the present invention provide an effective diagnostic tool for screening WSBV infection in animal host organisms, in particular shrimps, to prevent the further spread of this viral disease.

  • Patent number: 6190865
    Abstract: A method of characterizing a nucleic acid molecule is disclosed. The method comprises synthesizing DNA in the presence of a reaction mixture comprising a nucleic acid template, a primer molecule, an enzyme that extends the primer so that a DNA molecule may be synthesized, four canonical deoxynucleoside triphosphates and at least one non-canonical deoxynucleoside triphosphate. The non-canonical deoxynucleoside triphosphate is incorporated into the synthesized DNA in place of a portion of only one canonical deoxynucleoside triphosphate. The synthesized DNA is treated with an N-glycosylase that excises a base portion of the non-canonical deoxynucleoside triphosphate from the synthesized DNA. The DNA is then treated in such a manner that the phosphodiester backbone of the DNA is broken at the abasic site, thus creating at least two DNA fragments. The fragments are separated according to size.

  • Patent number: 6190870
    Abstract: Tumor cells, particularly carcinoma cells, are separated from peripheral blood by magnetic sorting. The tumor cells are magnetically labeled with antibodies directed to tissue specific antigens, preferably cytoplasmic proteins. Labeling for cytoplasmic antigens is accomplished first permeabilizing, then fixing the cells. The cells are separated on a magnetic matrix. The number of tumor cells in the enriched fraction is used to calculate the number of tumor cells present in a patient hematopoietic sample.

  • Patent number: 6190871
    Abstract: The invention features immunoreagents which neutralize the Human Immunodeficiency Virus Type 1 (HIV-1) by binding to a novel conserved epitope of the HIV-1 gp120. These immunoreagents exhibit a broad neutralizing effect upon HIV attachment to host cells, and are therefore useful in the detection, prevention, amelioration and treatment of HIV disease, primarily AIDS (Acquired Immunodeficiency Syndrome) and ARC (AIDS Related Complex). More particularly, the invention relates to novel human monoclonal antibodies selectively reactive to a conserved conformation dependent determinant of the HIV-1 gp120, derivatives thereof, cell lines that produce these antibodies, and the use of the monoclonal antibodies and their derivatives for the detection, prevention, amelioration and treatment of HIV related disease.
