  • Patent number: 6117648
    Abstract: Blood coagulation factor XII (FXII) is activated using a receptor for globular heads of the complement component Clq. The receptor (gC1qr) is a protein and provides a more faithful in vitro reproduction of the actual FX-II-activating reaction which occurs in living organisms. The protein receptor, gClqR may be obtained in at least substantially pure or isolated form by recombinant genetic engineering techniques or by isolation from animal cell membranes to which the complement component Clq binds. The receptor may be separated, purified, or isolated from cell membranes. The activation of the blood coagulation factor XII may be conducted in: 1) an animal plasma, 2) a reconstituted plasma kallikrein-kinin system, or 3) an at least substantially pure blood coagulation factor XII. The activation with the receptor is preferably conducted in the presence of zinc ions.

  • Patent number: 6103273
    Abstract: A pharmaceutical composition for the treatment of alopecia areata and male pattern baldness is preferably made from boric acid, zinc oxide, and starch. The method of the present invention comprises applying the pharmaceutical composition of the present invention to a person's scalp. The pharmaceutical composition of the present invention can comprise 10 parts by weight starch, 60 parts by weight boric acid, 40 parts by weight zinc oxide, and 500 parts by weight water. The dry ingredients (starch, boric acid, and zinc oxide) are mixed together, then the water is added. The mixture is boiled for 20 minutes, stirring continuously. The mixture will thicken, become smooth, and the final consistency will have minute lumps within the liquid. Preferably, before the pharmaceutical composition of the present invention is applied to the scalp, the bald spots are scrubbed with either pure lamb's wool or a soft-bristled brush made of animal hair. This cleanses the residue from the skin.

  • Patent number: 6100051
    Abstract: A process of microdissection where a tissue sample is conventionally visualized in a microscope. A selectively activatable convex surface is provided, preferably on the periphery at the distal end of a rod. This selectively activatable convex surface when locally activated, typically with a laser through an optic light path in the microscope, provides the activated region with adhesive properties. The tissue sample has at least one portion, which is to be extracted is identified. This identified portion is contacted with a portion of the selectively activatable convex surface on the periphery of the rod. When the convex surface is locally activated, typically by exposure to laser light in the footprint of the desired portion, an adhesive transfer surface on the selectively activatable convex surface is activated which adheres to the desired cells in the footprint of the desired portion.

  • Patent number: 6087088
    Abstract: Novel binding assay techniques have been developed which improve accuracy and sensitivity via accounting for interfering factors. They rely on use, in a simultaneous incubation, of two or more different labels, some of which are used primarily to detect analyte, and others to detect interfering substances originating in the sample. The mathematical relationships between the labels allow corrections that lead to more accurate and sensitive determination of the presence and concentration of the analyte.

  • Patent number: 6063588
    Abstract: This invention provides a method of diagnosing periodontal disease in a subject by detecting elevated concentrations of .beta.-glucuronidase in saliva from the subject. The concentration of .beta.-glucuronidase in the subject's saliva may be determined by adding to a sample of the saliva a substrate for .beta.-glucuronidase and measuring the amount of a product produced by the reaction of .beta.-glucuronidase on the substrate. Also, the concentration of .beta.-glucuronidase in the subject's saliva may be determined by adding to a sample of saliva a labeled antibody specific for .beta.-glucuronidase and measuring the amount of labeled antibody which complexes with .beta.-glucuronidase present in the saliva.

  • Patent number: 6063591
    Abstract: A system is used for determining efficacy of a sterilization cycle. A biological sterilization indicator exhibits fluorescence in response to biological activity which is indicative of bacterial growth in the biological sterilization indicator. The biological sterilization indicator is exposed to the sterilization cycle and is placed in a fluorescence reading apparatus. The fluorescence from the biological sterilization indicator is read to obtain a first fluorescence reading. The fluorescence from the biological sterilization indicator is re-read to obtain a second fluorescence reading. The efficacy of the sterilization cycle is determined based on the first and second fluorescence readings.
