  • Publication number: 20230149326
    Abstract: A pharmaceutical or food composition including alverine, 4-hydroxy alverine, a derivative thereof, or a salt thereof and their uses are disclosed. The composition is useful for preventing, alleviating, or treating muscular weakness-related diseases. When myoblasts are treated with the alverine, 4-hydroxy alverine, derivative thereof, or salt thereof, differentiation into myotubes is promoted. Therefore, the alverine, 4-hydroxy alverine, derivative thereof, or salt thereof can be effectively used in the promotion of differentiation of myoblasts and the prevention, alleviation, or treatment of muscular weakness-related diseases.

  • Publication number: 20210261969
    Abstract: The present invention relates to a pharmaceutical composition for preventing or treating a muscular disease or cachexia, comprising, as an active ingredient, a miRNA located in Dlk1-Dio3 cluster or a variant thereof. In the present invention, it has been found that expression of miRNAs located in the Dlk1-Dio3 cluster is decreased as age increases. In particular, in a case where most of the miRNAs are over-expressed in fully differentiated myotubes, it has been confirmed that the diameter of the myotubes increases. In addition, also in a tumor-induced cachexia mouse model, it has been confirmed that cachexia was improved by inhibiting Atrogin-1 protein. Accordingly, the miRNA located in the Dlk1-Dio3 cluster or a variant thereof can be usefully utilized for the treatment and prevention of an Atrogin-1-dependent muscular disease and cachexia.

  • Patent number: 10019807
    Abstract: A method and device for detecting connected pixels in a two-dimensional (2D) image having a plurality of pixels each having X-Y coordinates may compare an upper-row pixel included in a Yth row with a lower-row pixel included in a Y+1th row depending on a comparison condition, wherein Y is a positive integer, and wherein when a difference in X coordinate between the upper-row pixel and the lower-row pixel is one or less, the upper-row pixel and the lower-row pixel are determined to be positioned adjacent each other, and when the difference in X coordinate is two or more, the upper-row pixel and the lower-row pixel are determined to be spaced apart from each other and update an index map that defines a relationship between index numbers of adjacent pixels depending on the determination to set pixels with the same or associated index number in the same pixel group.
