Abstract:
PURPOSE: A refrigerator door guard assembly structure, capable of convenient attachment and detachment, is provided to efficiently and conveniently attach and detach a door guard by supplying the visual information about the assembly spot of the door guard. CONSTITUTION: A refrigerator door guard assembly structure(300) comprises an assemblage groove and an assembling protrusion(320a). The assemblage groove is formed in the inner surface of both sides of the refrigerator door. The upper side of the assemblage groove is formed in an arc shape. The assembling protrusion is formed on the outer side of the door guard. The assembling protrusion comprises a vertical face formed on a curved face.
Abstract:
The present invention relates to hyaluronic acid-based hydrogel including a cell differentiating agent or a cell activity inducing material and produced using cucurbituril and polyamine, a cell treatment-assisting composition including the hydrogel, a cell treating composition including the hydrogel including a cell differentiating agent or a cell activity inducing material and mesenchymal stem cells, and a cell treatment-assisting composition including the hyaluronic acid-based hydrogel produced using cucurbituril and polyamine. Another purpose of the present invention relates to a cell treatment composition including the hydrogel and mesenchymal stem cells. The hyaluronic acid-based hydrogel provided in the present invention plays a role as a supplementary material for supporting stem cells which expresses a treatment material used as a cell treatment agent so as to promote the secretion of the treatment material and increase cell survival rates, so that the treatment effects of the cell treatment agent can be maximized. Accordingly, the hyaluronic acid-based hydrogel can be widely used to develop a cell treatment agent which exhibits improved effects.
Abstract:
A manufacturing method of a nano structure using self-assembled block copolymer is provided to easily form a nano structure on a metal surface. A manufacturing method of a nano structure using self-assembled block copolymer comprises the following steps: a step for forming a metal thin film on a substrate(a); a step for treating a surface of the metal thin film using oxygen plasma(b); a step for neutralizing the surface of the metal thin film(c); a step for coating a block copolymer on the surface(d); and a step for forming a self-assembled nano structure by annealing and exposing the block copolymer(e).
Abstract:
PURPOSE: An anticancer stem cell medicine is provided to have an excellent anticancer effect compared with the existing drug, thereby being used effectively for treatment of various solid cancers and metastatic cancers. CONSTITUTION: A DNA cassette includes the respective nucleic acid sequence for coding dodecameric TRAIL (TNF related apoptosis inducing ligand) and suicide gene. A recombinant expression vector comprises the DNA cassette. The recombinant expression vector is derived from adenovirus. The recombinant adenovirus is made by the recombinant expression vector. The host cell is transfected with the recombinant adenovirus. The anticancer medicine contains the host cell.
