  • Publication number: 20240116983
    Abstract: Compounds having activity for lowering parathyroid hormone levels are described. In one embodiment, the compounds are comprised of a contiguous sequence of subunits, X1—X2—X3—X4—X5—X6—X7, wherein the X1 subunit comprises a thiol-containing moiety and the distribution of charge on the X2—X7 subunits provides the desired activity. Methods of using the compounds for treating hyperparathyroidism, bone disease and/or hypercalcemic disorders are also described, and in particular, methods for lowering plasma PTH and serum calcium are provided. The compounds can be used to treat subjects having, for example: primary, secondary or tertiary hyperparathyroidism; hypercalcemia of malignancy; metastatic bone disease; or osteoporosis.

  • Patent number: 7720049
    Abstract: A service broker of telecommunications networks is described herein. According to one embodiment, in response to a telephony call event from a subscriber to be serviced by a plurality of services, for each of the plurality of services, a service description associated with the respective service is examined to identify which of the plurality of service is capable of handling the telephony call event, where the service description semantically describes the respective service. Thereafter, the telephony call event is distributed to one or more of the identified services that are capable of handling the telephony call event, where the telephony call event is processed by the one or more services. Other methods and apparatuses are also described.

  • Publication number: 20040234954
    Abstract: A thin film made of a stiff polymer and having indentations on its surface, and methods of making and using the thin film are disclosed. The surface includes a plurality of indentations, the shape of each indentation corresponding to an outer surface of an imprint moiety, such as an animal, bacterial, or plant cell. The thin film can be mounted on a detector, which can be used to selectively bind to and detect the imprint moiety in a sample, e.g., a biological or environmental sample, at a minimum concentration of as low as 500 to 1000 imprint moieties per milliliter of sample.

  • Patent number: 6486344
    Abstract: The present invention is based on a series of acrylic cross-linking agents containing two or more dehydroalanine moieties (H2C═C(NHCOR′)COOR) per monomer. Monomers of the general structure H2C═C(NHCOCH3)COO(CH2)iOO(CH3CONH) C═CH2 with i=4, 5, and 8 can be polymerized or copolymerized under UV-curing conditions or by simple heating above melting point, leading to cross-linked polymeric materials. When polymerized on metallic surfaces, exceptional adhesion is obtained with no need for additional adhesion enhancers.
