  • Patent number: 11969397
    Abstract: The present invention relates to a composition for preventing or treating transplantation rejection or a transplantation rejection disease, comprising a novel compound and a calcineurin inhibitor. A co-administration of the present invention 1) reduces the activity of pathogenic Th1 cells or Th17 cells, 2) increases the activity of Treg cells, 3) has an inhibitory effect against side effects, such as tissue damage, occurring in the sole administration thereof, 4) inhibits various pathogenic pathways, 5) inhibits the cell death of inflammatory cells, and 6) increases the activity of mitochondria, in an in vivo or in vitro allogenic model, a transplantation rejection disease model, a skin transplantation model, and a liver-transplanted patient, and thus inhibits transplantation rejection along with mitigating side effects possibly occurring in the administration of a conventional immunosuppressant alone.

  • Publication number: 20240135595
    Abstract: The present invention relates to a method and apparatus for encoding a displacement video using image tiling. A method for encoding multi-dimensional data according to an embodiment of the present disclosure may comprise: converting the multi-dimensional data into one or more frames with two-dimensional characteristics; generating one or more frame groups by grouping the one or more frames with pre-configured number units; reconstructing frames belonging to each frame group into a tiled frame; and generating a bitstream by encoding the tiled frame. Here, the tiled frame may be constructed with one or more blocks, and each block may be constructed by rearranging pixels existing at the same location in the frames.
