Publication number: 20240125804Abstract: 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.Type: ApplicationFiled: December 22, 2023Publication date: April 18, 2024Inventors: Jae-Sung BAE, Hee Kyung Jin, Ju Youn Lee, Seung Hoon Han

Patent number: 11024726Abstract: 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.Type: GrantFiled: November 15, 2019Date of Patent: June 1, 2021Assignee: UNIST (Ulsan National Institute of Science and Technology)Inventors: Ki Suk Lee, Dae Han Jeong, Hee Sung Han, Nam Kyu Kim
