  • Publication number: 20130295678
    Abstract: In one embodiment, a test strip for testing for cholesterol-related blood analytes in whole blood includes a red blood cell separation layer, the red blood cell separation layer separating red blood cells from a blood sample applied to the test strip as the blood sample flows downward through the red blood cell separation layer. The test strip further includes a reaction layer receiving the blood sample from the red blood cell separation layer, the reaction layer including POE-POP-POE block copolymer, a surfactant, and a reflectivity changing reactant, the POE-POP-POE block copolymers solubilizing essentially only non-LDL cholesterol analytes, the non-LDL cholesterol analytes reacting with the reflectivity changing reactant in order to change a reflectivity of the blood sample.

  • Publication number: 20130023553
    Abstract: Provided are methods for reducing the addiction potential and/or reducing one or more CNS-side effects related to the administration of an opioid analgesic drug by administering the opioid analgesic drug in the form of an oligomeric polyethylene glycol conjugate compound. The compounds provided demonstrate notably reduced potential for substance abuse, and possess altered pharmacokinetic profiles relative to the opioid agonists alone, but are not subject to the risk of physical tampering that allows for the recovery and abuse of the opioid agonist associated with certain alternative delivery formulations.
