  • Patent number: 8618072
    Abstract: The present invention relates to a composition comprising a Ninjurin1 expression or activity inhibitor for the prevention and treatment of inflammatory disease. Ninjurin1 protein is specifically expressed in macrophages around blood vessels, increases cell-cell adhesion and cell-matrix adhesion, increases expressions of Wnt7b (Wingless-type MMTV integration site family, member 7B) and Ang2 (angiopoietin-2), but reduces expression of Ang1 to induce apoptosis of vascular endothelial cells. In addition, Ninjurin1 protein is up-regulated when inflammation is induced and induces iNOS expression as well as increased NO generation. Therefore, the Ninjurin1 protein expression or activation inhibitor can be effectively used as an active ingredient of a composition for the prevention and treatment of inflammatory disease.

  • Patent number: 8599809
    Abstract: In the wireless mesh network including a sender, a receiver, and a plurality of access points disposed between the sender and the receiver, available transmission paths between the sender and the receiver are determined; transmission expected values are calculated for the transmission paths; and a transmission path having a minimum transmission expected value is set as an actual transmission path. The transmission expected value is a sum of expected transmission counts, which is a reciprocal of multiplication of forward transmission success rate and backward transmission success rate of a communication link between the nodes disposed on the transmission paths. When an access point can transmit a packet concurrently with another access point, the expected transmitted count is reduced by half.
