Disclosed is a composition for forming an injectable hydrogel. The composition includes 1% by weight or less of a graphene-based material and 5% by weight or more of a triblock copolymer. The triblock copolymer may be a copolymer represented by Formula 1: wherein n is an integer from 8 to 540, m is an integer from 16 to 70, and R is H or a vinylcarbonyl group (CH

The present invention relates to identification of Zinc-ZIP8-MTF1 axis that plays an important role to OA (osteoarthritis) pathogenesis process and a novel use thereof. According to the present invention, ZIP8 and MTF1 of the present invention increase in the expression in joint disease induced cells or cartilage tissue, and induce the expression of various matrix-degrading enzymes (e.g., MMP-3, MMP-9, MMP-12, MMP-13 and ADAMTS-5 etc.). In addition, when the expression of ZIP8 or MTF1 is inhibited in cells or tissues of animals (e.g., human, mouse), OA pathogenesis is inhibited. Therefore, the ZIP8 and MTF1 of the present invention may be applied to the diagnosis or prognosis of joint diseases, and may be used for the development of therapeutics for joint diseases using these.

A system, method, and apparatus for delayed optical logic gates based on slow light and enhanced nondegenerate four-wave mixing processes, where a single or multiple delayed optical routers are utilized for dark resonance interactions in which two-color lasers interact with a three-level nonlinear optical medium comprised of two ground states and one excited state through the nondegenerate four-wave mixing processes. The delayed optical logic mechanism is based on combination of single or multiple dark resonance-induced two-photon coherence conversion via slow light phenomenon. The two-photon coherence induced on the ground states is optically detected via nondegenerate four-wave mixing processes. The nondegenerate four-wave mixing generation is enhanced owing to dark resonance or electromagnetically induced transparency. The delayed optical logic gates have potential to keep up ultra-high-bandwidth optical information processing using relatively slow electronic processing devices.
