  • Patent number: 6200302
    Abstract: Devices and methods are disclosed for the percutaneous administration of a composition to a desired in vivo location. The composition comprises a biologically active substance and a pharmaceutically acceptable carrier. The pharmaceutically acceptable carrier is preferably non-solid and a polymer, which is preferably capable of being transformed into a gel, thus allowing timed-released delivery of the substance. A preferred use for this invention is to provide local delivery of biologically active substances for the prevention of restenosis following angioplasty or other blood vessel injury.

  • Patent number: 6187044
    Abstract: Compositions and methods are disclosed for filling prostheses for implantation into human soft tissue. The compositions comprise at least one nonionic surfactant, such as a polysorbate, which can be provided to fill a physiologically compatible shell or containment sac of the prosthesis. The liquid compositions of the present invention have a relatively high viscosity and are quickly absorbed from body tissues, metabolized and excreted with no known adverse effect. The compositions can be injected into the physiologically compatible shell either before, during or after the surgical implantation procedure.

  • Patent number: 6120287
    Abstract: An orthodontic force measuring apparatus includes a dental replica which includes a first tooth replica and a second tooth replica. The first tooth replica is moveable relative to the second tooth replica. The apparatus also includes an orthodontic appliance secured to both the first tooth replica and the second tooth replica of the dental replica. The apparatus further includes a force measuring device operatively coupled to the first tooth replica. The force measuring device is configured so as to measure force exerted on the first tooth replica by the orthodontic appliance. A method of measuring orthodontic force is also disclosed.

  • Patent number: 6116070
    Abstract: Described are unique prosthesis systems including superplastically-formed prosthetic elements, and methods and an apparatus for forming such elements. A preferred dental prosthesis system includes at least two osseointegrated fixtures, abutments attached to the fixtures, a bar member interconnecting the abutments, and a prosthesis detachably connected to the bar member, wherein the prosthesis includes a superplastically-formed metal element having a surface conforming to the bar member and abutments, a resin denture base attached to the metal element, and artificial teeth mounted on the resin denture base. The preferred prosthetic components are prepared by superplastic forming under temperature conditions which are repeatedly cycled above and below the transformation temperature of the metal being formed.

  • Patent number: 6090590
    Abstract: Non-template 3' nucleotide addition to a transcript is reduced by transcribing a transcript from a template comprising an ultimate and/or penultimate 5' ribose having a C'2 substituent such as methoxy, which reduces non-template 3' nucleotide addition to the transcript. The methods are shown to be applicable to a wide variety of polymerases, including Taq, T7 RNA polymerase, etc.

  • Patent number: 6046036
    Abstract: Described are DNA-repair fusion proteins of multiple, complementary DNA repair proteins and having the activity of each protein, and related polynucleotides and vectors. The proteins, when expressed in cells, e.g., hematopoietic cells, increase the survival rate of the cells when contacted with chemotherapeutic agents. Also described are transgenic animal models wherein these proteins are expressed in essentially all cells of the animal. Such animal models are useful for instance in testing chemotherapeutic agents.
