  • Publication number: 20240130892
    Abstract: Glaucoma is a type of eye disease caused by high intraocular pressure (IOP). An increase in IOP causes damage to the appearance and function of the optic nerve and, when left untreated, leads to vision loss. However, once inserted, the conventional aqueous humor drainage devices implanted to control IOP continuously discharge a certain amount of aqueous humor regardless of how high or low the IOP is and thus have difficulty in effectively controlling the IOP. The present disclosure, which has been devised to address the above problems, relates to a novel aqueous humor drainage device for controlling IOP. The aqueous humor drainage device of the present disclosure, which is a double-layer aqueous humor drainage device having a tube made of a shape memory polymer included therein, can control both low IOP and high IOP and thus has an excellent effect of maintaining IOP within a clinically acceptable range.

  • Publication number: 20240082387
    Abstract: The present invention relates to a fusion protein comprising a SARS-CoV-2-derived receptor-binding domain and a nucleocapsid protein, and the use thereof. The fusion protein comprising a coronavirus-derived receptor-binding domain and a nucleocapsid protein is highly applicable to a multivalent vaccine composition having greatly improved in-vivo half-life and remarkably superior efficacy compared to an immunogenic composition comprising only a receptor-binding domain. In particular, the fusion protein can greatly improve the titer of the coronavirus-specific antibody formation and T-cell immune response, and is thus useful for the prevention and treatment of coronaviruses comprising SARS-CoV-2.
