  • Patent number: 8828173
    Abstract: Reversibly and irreversibly-linking amino-polysiloxanes, methods of making such amino-polysiloxanes, and systems and methods of using such amino-polysiloxanes for the containment and/or remediation of a release and/or spill of a crude oil, a petroleum product and/or a chemical is described. Gels and/or emulsions formed from the combination and/or contacting of such an amino-polysiloxane with these materials can be used to recover these oils or chemicals while allowing the amino-polysiloxane to be recovered and reused to clean up or contain additional materials. Such amino-polysiloxanes can be used as well for the selective uptake of one component of liquid mixtures when such mixtures contain more and less lipophilic components. Methods of making and using adhesive and sealants containing such amino-polysiloxanes are described.

  • Patent number: 8816095
    Abstract: Disclosed are molecules and their synthesis, for use in blocking gated ion channels such as voltage-gated sodium channels (VGSCs) and prostate voltage sodium channels (PVSCs). These inhibitors have superior blocking efficacy, for instance in displacing the radioligand [3H]-Batrachotoxin-B ([3H]-BTX-B) that binds to site 2 of a VGSC. The molecules of the invention comprise a moiety which increases the binding affinity of molecules for the protein binding site in prostate cancer cells (PCs), and which is also fluorescent. In one embodiment the invention molecules are an inhibition system that can be used to target over-abundant or hyperactive VGSCs selectively in pain, epilepsy or prostate cancer, inhibiting the proliferation of PCs. The fluorescent moiety also facilitates screening, tracking, and pharmacodynamic studies of the drug in a biological system both in vitro and in vivo.

  • Publication number: 20140178296
    Abstract: The present invention is in the fields of drug delivery, cancer treatment and diagnosis and pharmaceuticals. This invention provides a method of making antibody- or antibody fragment-targeted immunoliposomes for the systemic delivery of molecules to treat and image diseases, including cancerous tumors. The invention also provides immunoliposomes and compositions, as well as methods of imaging various tissues. The liposome complexes are useful for encapsulation of imaging agents, for example, for use in magnetic resonance imaging. The specificity of the delivery system is derived from the targeting antibodies or antibody fragments.

  • Publication number: 20140134564
    Abstract: A dental arch bar system includes upper and lower dental arch bars having movable transverse arms and ligature connectors. Fasteners secure the transverse arms to a subject's maxilla and mandible. Ligatures are secured around upper and lower ligature connectors to achieve intermaxillary fixation. A method is also disclosed for using the arch bar system to achieve intermaxillary fixation by securing the arch bars against opposing dental arches with ligature connectors of the upper and lower arch bar generally aligned. In some embodiments, a single dental arch bar is utilized and one or more ligature connectors (such as screws) are fixed directly in the bone of the opposite jaw. Ligatures then are secured to arch bar ligature connectors and the opposing ligature connectors.

  • Publication number: 20140121485
    Abstract: A device contains individually controllable sites for electrochemically monitoring an analyte in interstitial fluid of a user. The sites include a conductive pattern attached at a first and second ends thereof to electrode material in a closed-circuit configuration for receiving a first predetermined voltage applied thereto in order to thermally ablate a stratum corneum of a user's skin to access the interstitial fluid and form an open-circuit configuration including first and second portions of the electrode material that are electrically isolated from each other; a sensing area deposited on at least one of the first and second portions of the electrode material; and a measuring component for receiving individual measurement data from the sensing area in response to a second predetermined voltage applied to the open circuit configuration. The individual measurement data is indicative of an amount of the analyte in the interstitial fluid.
