  • Publication number: 20240125804
    Abstract: The present invention relates to a pharmaceutical composition for preventing or treating neurodegenerative diseases comprising a COX2 acetylating agent as an active ingredient and, more particularly, to a pharmaceutical composition for preventing or treating neurodegenerative diseases comprising, as an active ingredient, a COX2 acetylating agent which exhibits an effect of inhibiting the deposition of amyloid-? in brain neurons, reducing excessive neuroinflammatory responses, and increasing the phagocytosis of amyloid-? in microglial cells. The pharmaceutical composition for preventing or treating neurodegenerative diseases comprising the COX2 acetylating agent as an active ingredient has the effects of alleviating neuroinflammation by promoting COX2 acetylation in neurons and secreting specialized pro-resolving mediators (SPMs) and thus, can be very useful in the development of a preventive or therapeutic agent for neurodegenerative diseases.

  • Patent number: 11651114
    Abstract: A method for designing a magnetic plate allowing magnetic particles contained in magnetic ink distributed at different densities includes estimating a distribution of the magnetic particles allowing the magnetic ink to be spread, estimating forms of magnetic field applying the magnetic force to the magnetic particles in order for the magnetic ink to be spread in a desired magnetic printing pattern within the printing layer, obtaining adjustment factors of the magnetic plate corresponding to the estimated forms of the magnetic field by using a model for which deep learning or machine learning has been performed using design conditions including at least one of an upper surface structure of the magnetic plate and a magnetization property of the magnetic plate and obtaining a parameter for the magnetic plate configured to form the magnetic printing pattern based on the obtained adjustment factors.

  • Patent number: 11024726
    Abstract: The present disclosure provides a skyrmion diode using skyrmions as information carriers. The skyrmion diode includes a magnetic body and a conductive body. The magnetic body has a skyrmion which is used as information carrier. The conductive body is disposed on or under the magnetic body. The conductive body includes a Dzyaloshinskii-Moriya interaction (DMI) region and a defect region. The DMI region is provided to induce DMI in a region of the magnetic body corresponding to the DMI region by the spin-orbit coupling of the conductive body and magnetic moments of the magnetic body. The defect region is provided to prevent the DMI from being induced in a region of the magnetic body corresponding to the defect region.
