  • Patent number: 8603519
    Abstract: A preparation is disclosed for producing enhanced blood flow in tissue thus causing beneficial effects such as promoting hair growth on scalp tissue lacking sufficient hair, restoring normal sexual function in males with erectile dysfunction. Specifically, this is a preparation which provides local delivery of the amino acid L-arginine, an important biological precursor to the main substance which is responsible for relaxation of blood vessels permitting enhancement of blood flow. In the preferred embodiments, the L-arginine is provided so that it can be topically applied to the scalp or penis. The preparation also contains an agent which aids in the transfer of L-arginine into the tissue. In the preferred embodiments this agent overcomes the resistance to transfer caused by the high charge density of L-arginine. In the preferred embodiments this means is high ionic strength created by addition of choline chloride, magnesium chloride and sodium chloride.

  • Patent number: 8575268
    Abstract: Disclosed is a thermoplastic resin composition containing a graft material and an organic peroxide group dispersion medium in which the graft material is dispersed. The graft material is obtained by melt-mixing a metal oxide fine particle having an organic peroxide group on the surface and a thermoplastic resin, and has a structure in which the thermoplastic resin is grafted to the metal oxide fine particle. The organic peroxide group on the surface of the metal oxide fine particle is preferably a peroxymonocarbonate group. The organic peroxide group on the surface of the metal oxide fine particle is preferably obtained by reacting a hydroxy group of a silicon oxide fine particle with an amino-modified silane coupling agent, thereby introducing an amino group to the surface of the silicon oxide fine particle, and then reacting the amino group with a compound having an ethylenically unsaturated group and an organic peroxide group.

  • Patent number: 8562836
    Abstract: The present invention relates to synthetic methods for grafting hydrophilic chains onto polymers, particularly hydrophobic polymers such as poly(vinyl chloride) (PVC), poly(vinylidene fluoride) (PVDF), and chlorinated polypropylene (cPP). Resulting polymers include comb polymers which can have a microphase-separated structure of hydrophilic domains provided by the hydrophilic chains. Articles prepared from these comb polymers, particularly derived from PVDF, include membranes for water filtration in which the hydrophilic domains provide a pathway for water transport. PVC can be plasticized by grafting the PVC with hydrophilic chains. In addition, such articles, particularly articles having biomedical applications, can display anti-thrombogenic properties.
