In particular, these include novel cationic lipids and nucleic acid-lipid particles that provide efficient encapsulation of nucleic acids and efficient delivery of the encapsulated nucleic acid to cells in vivo. The compositions of the present invention are highly potent, thereby allowing effective knock-down of a specific target protein at relatively low doses. In addition, the compositions and methods of the present invention are less toxic and provide a greater therapeutic index compared to compositions and methods previously known in the art.

  • Patent number: 8394393
    Abstract: A composite material containing polymeric nanofibers, themselves containing NO-donor molecules, imbibed with an elastomer matrix is permeable to both water and gas so that dissociation reactions in the presence of water releases NO gas in a sustained manner. The NO-donor nanofibers may be formed by synthesizing acceptable NO-donor molecules, blending such molecules in solution with PVP, PCL or PVAc, electrospinning the blend at relatively high voltage for form fiber mats, applying PDMS rubber to the fiber mat and crosslinking it. The resulting NO-releasing electrospun fiber composite may be used in medical devices such as catheters, stents, or vascular grafts, with the purpose of releasing nitric oxide within a controlled rate and for a sustained period of time, as well as other known medical applications for NO.

  • Publication number: 20130059000
    Abstract: A process for making hemoglobin based oxygen carrier (HBOC) containing pharmaceutical composition suitable for oral delivery and the composition formed thereby are described. There are three exemplary composition configurations which include (1) hemoglobin-loaded nanoparticles solution, (2) enteric-coated hemoglobin capsules and (3) enteric-coated hemoglobin tablets. To facilitate the bioavailability and bio-compatibility of hemoglobin, intestinal absorption enhancers are added in each of the HBOC formulations. Protective layers ensure delivery of an intact hemoglobin structure in intestinal tract without degradation in the stomach. The HBOC formulations may be used for preventive or immediate treatment of high altitude syndrome (HAS) or for treatment of hypoxic conditions including blood loss, anemia, hypoxic cancerous tissue, and other oxygen-deprivation disorders.
