Patent number: 5663317Abstract: The invention provides nucleic acids encoding one or more hyper-invasive genes within the hil locus (hyper-invasion locus) or fragments thereof, methods for making attenuated microorganisms and identifying such hyper-invasive nucleic acids as well as mutant microorganisms wherein one or more hyper-invasive genes within the hil locus are modified to attenuate the invasive phenotype of the microorganism. The methods of the invention utilize conditions which repress invasiveness in an otherwise invasive microorganism. The method comprises mutating an invasive microorganism to form a plurality of mutant microorganisms. The thus formed mutants are exposed to conditions which repress invasiveness of the parental invasive microorganism. At least one mutant microorganism is then detected which exhibits an increase in invasiveness as compared to the parental invasive microorganism.Type: GrantFiled: September 1, 1994Date of Patent: September 2, 1997Assignee: The Board of Trustees of the Leland Stanford Jr. Univ.Inventors: Stanley Falkow, Catherine A.

Patent number: 5631167Abstract: Improved assay methods utilizing stable, enzymatically triggered chemiluminescent 1,2-dioxetanes with improved water solubility are provided. Assays are performed by a capsule chemistry analytical assay method wherein fluid capsules comprising discrete aqueous segments containing either a chemiluminescent dioxetane reagent or an activating agent separated by an oil-based isolating fluid are flowed through a conduit, and subsequently reacted to produce light.The improvement comprises using a dioxetane substituted with two or more water-solubilizing groups disposed on the dioxetane structure to provide the chemiluminescence. Compositions comprising such a dioxetane, a non-polymeric surfactant enhancer and optionally a fluorescer, provide enhanced chemiluminescence and eliminate the problem of reagent carryover when used in assays performed on capsule chemistry analytical systems.Type: GrantFiled: July 31, 1995Date of Patent: May 20, 1997Assignees: Bayer Corporation, Board of Governors Wayne State Univ.Inventors: Robert F.

Patent number: 5628630Abstract: A method of designing a skeletal implant comprises measuring the width, height, and elastic modulus of the bone to be implanted, generating a macro-design of the implant based on the width and height of the bone, and determining a micro-design for the implant, based on the measured elastic modulus, to ensure that strain in the bone is kept in a range to promote bone growth and to minimize bone resorption, during functional loading. For threaded implants, the shape of the thread is chosen so that bone strain adjacent the threaded attachment surface of the implant is between about 100 and 3000 microstrain. A device for implanting into the existing bone and for attaching a dental prosthesis thereto has a crest portion, a base portion, and a configuration for securing the base portion to the existing bone.Type: GrantFiled: December 15, 1994Date of Patent: May 13, 1997Assignee: Univ. of Alabama at BirminghamInventors: Carl F.

Patent number: 5623423Abstract: An MPEG-2 decoder circuit achieves smaller circuit area, and hence lower cost, by using circuitry, including ROMs, designed to implement residue arithmetic to calculate discrete cosine transforms in a pipelined or iterative fashion. A variable-length decoder based on ROM-like PLAs parses the stream of data to separate audio from video data and to direct the necessary operations on the data elements. The decoder and data flow through the system are controlled by a conditional MOVE processor, which is implemented as a data memory.Type: GrantFiled: December 12, 1994Date of Patent: April 22, 1997Assignee: Univ. of TexasInventor: G.

Patent number: 5622946Abstract: Texaphyrins are provided for use as radiation sensitizers. Advantageous properties of texaphyrins for use as a radiation sensitizer include: i) a low redox potential which allows radiation-induced hydrated electrons to flow to texaphyrin rather than neutralizing hydroxyl radicals, allowing hydroxyl radicals to cause cellular damage, ii) a relatively stable texaphyrin radical that reacts readily to covalently modify neighboring molecules causing further cellular damage, iii) intrinsic biolocalization, and iv) indifference to the presence or absence of O.sub.2. These properties allow texaphyrins to be particularly effective for treating the hypoxic areas of solid neoplasms. Methods of treatment for an individual having a neoplasm or atheroma include the use of a texaphyrin as a radiation sensitizer and as an agent for photodynamic tumor therapy, or the use of a texaphyrin for internal and for external ionizing radiation. Novel texaphyrins are provided.Type: GrantFiled: May 10, 1995Date of Patent: April 22, 1997Assignees: Pharmacyclics, Inc., Board of Regents, Univ. of Tex. Sys.Inventors: Jonathan L.
