Abstract: A strain sensor may have a conductive elastic yarn including a first fiber having a predetermined length and a shape of a fiber yarn and a second fiber having electrical conductivity and a sheet shape. The strain sensor may have a pair of wiring members electrically connected to both ends of the conductive elastic yarn. The conductive elastic yarn, with the second fiber wrapped around the first fiber, is twisted in a coil shape.

Abstract: The present disclosure relates to an organic electroluminescent compound, a plurality of host materials, and an organic electroluminescent device comprising the same. By comprising the compound according to the present disclosure or by comprising a specific combination of compounds according to the present disclosure as a plurality of host materials, it is possible to produce an organic electroluminescent device having improved driving voltage, luminous efficiency, and/or lifetime properties compared to the conventional organic electroluminescent devices.

Abstract: The present disclosure relates to a plurality of host materials comprising a first host material comprising a compound represented by formula 1, and a second host material comprising a compound represented by formula 2, and an organic electroluminescent device comprising the same. By comprising a specific combination of compounds as host materials, it is possible to provide an organic electroluminescent device having lower driving voltage, higher luminous efficiency, higher power efficiency, and/or superior lifespan characteristics compared to conventional organic electroluminescent devices.

Abstract: The present invention provides a chimeric antigen receptor and natural killer cells expressing the same, and particularly, a chimeric antigen receptor (CAR) which includes an intracellular signaling domain including the whole or a portion of an OX40 ligand (CD252), thereby having excellent effects of increasing anticancer activity of immune cells, and immune cells expressing the same.

Abstract: A cloth for mattress including a knitted fabric that is knitted from blended yarns contains flame retardant rayon fibers, modacrylic fibers, polyimide fibers, and low-melting polyester fibers. The cloth for mattress can be obtained by producing blended yarns containing the flame retardant rayon fibers, the modacrylic fibers, the polyimide fibers, and the low-melting polyester fibers, and producing a knitted fabric by knitting the blended yarns. The cloth for mattress has excellent flame retardancy, ensures easy handling when used to cover a mattress, is resistant to pilling without reducing the strength of the blended yarns, and is also safe for contact with the human body.

Abstract: Disclosed is an ophthalmic drug delivery system intended for insertion into an eye, the ophthalmic drug delivery system containing: a carrier comprising crosslinked hyaluronic acid; and a drug loaded in the carrier. Also disclosed is a method for producing an ophthalmic drug delivery system, the method comprising steps of: preparing a first solution containing hyaluronic acid and water; preparing a second solution containing 1,4-butanediol diglycidyl ether (BDDE) and water; sterilizing the first solution and the second solution separately; preparing a third solution by mixing the sterilized first solution and second solution together; and polymerizing the hyaluronic acid by incubating the third solution.

Abstract: Provided is a pharmaceutical combination comprising an antibody specific for CD19 and a natural killer cell, and a treatment method using the same. Such a pharmaceutical combination is capable of exhibiting synergistic therapeutic effects on a malignant tumor of B-cell origin such as non-Hodgkin's lymphoma, chronic lymphocytic leukemia, and/or acute lymphoblastic leukemia.

Abstract: The present invention provides a chimeric antigen receptor and natural killer cells expressing the same, and particularly, a chimeric antigen receptor (CAR) which includes an intracellular signaling domain including the whole or a portion of an OX40 ligand (CD252), thereby having excellent effects of increasing anticancer activity of immune cells, and immune cells expressing the same.
