  • Patent number: 11946031
    Abstract: Provided is yarn for a cell culture scaffold. The yarn for a cell culture scaffold according to an exemplary embodiment of the present invention includes slitting yarn produced by cutting a compressed nanofiber web to a predetermined width. Accordingly, by creating microenvironments suitable for migration, proliferation and differentiation of cells, cell viability may be enhanced and cells may be three-dimensionally proliferated. In addition, a scaffold according to the present invention has a mechanical strength sufficient for prevention of disruption of the scaffold which occurs during cell culture, such that cells may be stably proliferated. Further, the scaffold according to the present invention uses slitting yarn formed of the compressed nanofiber web, thereby having pores with various sizes, and therefore cell proliferation and cell viability may be enhanced by creation of an extracellular matrix-like environment.

  • Publication number: 20240073416
    Abstract: The present invention relates to an apparatus and method for encoding and decoding an image by skip encoding. The image-encoding method by skip encoding, which performs intra-prediction, comprises: performing a filtering operation on the signal which is reconstructed prior to an encoding object signal in an encoding object image; using the filtered reconstructed signal to generate a prediction signal for the encoding object signal; setting the generated prediction signal as a reconstruction signal for the encoding object signal; and not encoding the residual signal which can be generated on the basis of the difference between the encoding object signal and the prediction signal, thereby performing skip encoding on the encoding object signal.

  • Publication number: 20230096789
    Abstract: A new use of hydroxyurea for preventing, alleviating, or treating systemic inflammatory response syndrome or sepsis is disclosed. Hydroxyurea can control the activity of neutrophils that are immune cells involved in inflammatory mechanisms, and thus can protect an individual from side effects or conditions caused by systemic inflammatory responses which can occur due to exposure to microorganisms such as bacteria or viruses. Thus, a pharmaceutical composition containing hydroxyurea as an active ingredient can prevent, alleviate, or treat systemic inflammatory response syndrome or sepsis in an individual and ultimately can remarkably increase the survival rate of the individual. The composition may be effective in preventing, alleviating, or treating neutrophilia which can occur when exposed to microorganisms such as bacteria or viruses, wherein the viruses include viruses for therapeutic purposes, such as oncolytic viruses as well as pathogenic viruses such as influenza virus or coronavirus.
