  • Patent number: 8329225
    Abstract: The present invention is a method for encapsulating active protein in a polymeric nanocarrier. The instant method employs homogenization at subzero temperatures so that enzyme activity is retained. Enzymes which can be encapsulated by the present method include, for example, antioxidant enzymes and xenobiotic detoxifying enzymes. Encapsulation of an enzyme protects it from protease degradation and increases therapeutic half-life. Advantageously, polymeric nanoparticles of the invention are permeable to enzyme substrates and therefore enzymes encapsulated by the instant method can exert their effect without release from the nanocarrier. Methods for decomposing a reactive oxygen species, protecting against vascular oxidative stress, and detoxifying a xenobiotic are also provided.

  • Patent number: 8206748
    Abstract: A powdery composition for nasal administration, where (1) the composition contains (i) a drug, (ii) a water-absorbing and gel-forming base material such as hydroxypropyl cellulose or hydroxypropylmethyl cellulose and (iii) a water-absorbing and water-insoluble base material such as crystalline cellulose or ?-cellulose, (2) wherein the amount of the water-absorbing and gel-forming base material is about 5-40 wt % based on the total of the water-absorbing and gel-forming base material and the water-absorbing and water-insoluble base material, and (3) wherein the drug is unevenly dispersed more on/in the water-absorbing and water-insoluble base material than on/in the water-absorbing and gel-forming base material.

  • Publication number: 20120156305
    Abstract: The disclosure provides methods for increasing genome stability of an embryonic stem (ES) cell or induced pluripotent stem (iPS) cell, increasing telomere length in an ES or iPS cell, or both, for example by contacting an ES or iPS cell with an agent that increases expression of Zscan4 in the cell. Methods for increasing the genome stability in a population of ES or iPS cells, increasing telomere length in a population of ES or iPS cells, or both, are provided, for example by selecting Zscan4+ ES or iPS cells from the population of ES or iPS cells (which can include both Zscan4+ and Zscan4? ES or iPS cells). Therapeutic methods of using ES or iPS cells expressing Zscan4 are also provided. Further provided are methods of treating cancer by administering a Zscan4 polynucleotide or Zscan4 polypeptide. Also provided are methods of inducing differentiation of isolated ES or iPS cells into germ cells.

  • Patent number: 8202540
    Abstract: The invention relates to superfine microparticles and nanoparticles and a process for their gentle preparation with exclusion of water or minimization of water and/or exclusion of plasticizers and/or reduced temperature load, in which a matrix material is subjected to a high-pressure homogenization process in an anhydrous or water-poor medium and/or at low temperatures, preferably room temperature (20° C.) and in particular below the freezing point of water, which leads to a gentle particle reduction with minimization of the impairment of the chemical stability of the homogenized material.

  • Patent number: 8202544
    Abstract: Non-viral vectors for delivering agents to a site within the body of an animal comprise a biocompatible nanoparticle conjugated to an avidin/biotin complex and a water soluble linear polymer comprising multiple binding sites. The agents to be delivered are conjugated to each of the multiple binding sites, thereby increasing the loading capacity of the system. Where the agents comprise siRNA, each biotin/avidin complex may carry greater than four siRNA. The biocompatible nanoparticle may also comprise a fluorescent dye for in vivo imaging.

  • Publication number: 20120128752
    Abstract: The invention relates to a method of manufacturing multi-phase microparticles. The method comprises dissolving at least three different polymers in a volatile organic solvent to obtain a first solution. The first solution comprises at least two cloud points, wherein the second cloud point is higher than the first cloud point. Viscosity of the first solution and the first and second cloud point are selected such that the at least three different polymers are immiscible with each other in the first solution. The first solution is dispersed into an aqueous continuous phase which comprises a surfactant to obtain an emulsion. The volatile organic solvent is evaporated from the emulsion. The total concentration of the at least three different polymers together in the emulsion before evaporation is below the first cloud point, or is above the first cloud point and below the second cloud point or is above the second cloud point.
