  • Patent number: 8619704
    Abstract: The present invention relates to a power saving in a wireless local area network including a plurality of access points providing at least one mobile station in each access point cell boundary with access service, the mobile station transits between an active mode and an idle mode. The power saving method includes grouping the access points into at least one paging group with a paging group boundary; determining if the a mobile station is in the idle mode in which the mobile station switches between an awake state and a doze state every predetermined time interval, or the active mode in which the mobile station is in the awake mode; and if the mobile station is in the idle mode enabling an idle handoff which occurs only when the mobile station crosses the paging group boundary. In the present invention, the handoff occurs when the mobile terminal crosses the paging group boundary but not the access point cell in the idle mode, resulting in reduction of power consumption.

  • Patent number: 8617546
    Abstract: Provided is an anticancer agent which comprises an anti-PD-1 antibody or an anti-PD-L1 antibody as an active ingredient, functioning to reverse the unresponsiveness of iNKT cells in which anergy has been induced by administration with an iNKT cell ligand. The anti-PD-1 or anti-PD-L1 antibody blocks the PD-1/PD-L1-mediated signaling pathway not only to prevent the iNKT cell ligand-induced iNKT cell anergy, but also to reverse the unresponsiveness of already anergic iNKT cells to produce cytokines. In addition, the anti-PD1 or anti-PD-L1 antibody ensures the potent anti-tumor activity of iNKT cells as demonstrated by a significant reduction in the number of metastatic nodules in B16F10 melanoma metastasis models in vivo. Collectively, the anticancer agent can be very useful in the treatment of cancer, particularly metastatic cancer.

  • Patent number: 8586099
    Abstract: The present invention relates to a method for preparing a bone graft substitute using bovine bone, and more particularly to a method for preparing a safe bone graft substitute which does not have the risk of infection with bovine spongiform encephalopathy, the method comprising treating bovine bone with sodium hypochlorite and treating the treated bone at a high temperature of more than 600° C. The bone graft substitute does not cause an immune response, because it is prepared by effectively removing lipids and organic substances from bovine bone having a structure very similar to that of the human bone. Also, it has excellent osteoconductivity, and is free of prion, and thus it does not have the risk of infection with bovine spongiform encephalopathy. According to the disclosed invention, the bone graft substitute having such advantages can be prepared in a simple manner.
