Abstract: A muscular atrophy-inducing agent containing, as an active ingredient, a hypometabolism-inducing substance selected from the group consisting of 3-iodothyronamine (T1AM), [D-Ala2,D-Leu5] enkephalin (DADLE), 5?-adenosine monophosphate (5?-AMP), and hydrogen sulfide (H2S), and a method for preventing or treating muscular hypertrophy; and a method for shrinking facial muscle are proposed. The muscular atrophy study model can provide a study model for an economic muscular atrophy study by using a hypometabolism-inducing substance which can be mass-produced, has an effect which may be usefully used by verification for screening of a drug for preventing or treating muscular atrophy, and can be usefully used as a compositions for preventing or treating muscular hypertrophy and a composition for facial muscle shrinkage through the muscular atrophy effect.

Abstract: The present invention relates to a method for manufacturing a polyimide-powder composite separator using water and a polyimide-powder composite separator manufactured by the method, and is environmentally friendly since an organic solvent is not used in the overall process of manufacturing the composite separator and has advantageous effects in terms of time, cost, and manufacturing process since a high temperature/high pressure environment is not required.

Abstract: The present invention relates to a pickering emulsion composition using polyimide particles and a method for preparing the same. The pickering emulsion stabilized by the polyimide particles according to the present invention has a very stable dispersed phase and does not cause flocculation, creaming, coalescence and phase separation even after a long time, and has an advantage of being capable of forming both an oil-in-water type emulsion and a water-in-oil type emulsion. Further, the polyimide particles used in the present invention can be synthesized in a simple manner and have partial wettability without the surface treatment and pH control so that they can be easily used for the emulsion stabilization.

Abstract: A conductive hydrogel includes: a first monomer; a second monomer; a crosslinking agent; a photoinitiator; a wetting agent; an electrolyte; and deionized water, wherein the first monomer is a 3-sulfopropyl acrylate potassium salt, and the second monomer is acrylic acid. The conductive hydrogel has high adhesivity, conductivity and moisture-retaining capacity and low skin irritancy compared to conventional hydrogels because it has the optimum composition ratio.
