Abstract: The present invention provides a peptide represented by formula (I) of X1-Leu-X2-Leu-X3 wherein X1 represents Glu or Asp, X2 represents His, Lys or Arg, X3 represents Asp or Glu, with Glu, Asp, Leu, His, Lys and Arg being respectively glutamic acid, aspartic acid, leucine, histidine, lysine and arginine; or a pharmaceutically acceptable salt thereof; a composition for the treatment or prevention of at least one selected from cartilage damage and arthritis, containing the same peptide or a pharmaceutically acceptable salt thereof as an active ingredient; and a composition containing the same peptide or a pharmaceutically acceptable salt thereof and TGF?1.

Abstract: Disclosed herein is a hair iron having upper and lower casings, a heat generating unit and a hinge connection unit. The hinge connection unit includes a hinge box secured to either of the upper and lower casings. First and second movable members each having a hinge shaft are provided in the hinge box, and move between a hinge coupling position and a hinge releasing position. An elastic member is elastically provided between the first and second movable members, and exerts an elastic force so that the hinge shaft moves to the hinge releasing position. A hinge-coupling retaining means is manipulated on an outside of the hinge box to move the hinge shaft to the hinge coupling position and simultaneously retain the hinge shaft in the hinge coupling position. A hinge-shaft connection lug is provided on a remaining one of the upper and lower casings, and has a hinge hole.

Abstract: Disclosed is a method of preparing high crystalline nanoporous titanium dioxide photocatalyst, capable of preparing the high crystalline nanoporous titanium dioxide photocatalyst in mass production through a simply synthesis method using an ultrasonification. The method includes the steps of (a) mixing a titanium precursor and a surfactant in a first solvent and performing a sol-gel reaction; (b) maturing a reactant obtained through the sol-gel reaction for 15 hours to 25 hours; (c) filtering the matured reactant and washing the matured reactant; (d) primarily drying the washed reactant at a temperature of 20° C. to 50° C. to obtain titanium sediments; (e) mixing the titanium sediments in a second solvent and performing an ultrasonification with respect to the mixed solution for 10 minutes to 120 minutes; and (f) secondarily drying the mixed solution, which has been subject to the ultrasonification, at a temperature of 15° C. to 45° C. to obtain titanium dioxide photocatalytic particles.

Abstract: Disclosed is a method of preparing high crystalline nanoporous titanium dioxide, in which the high crystalline nanoporous titanium dioxide, which is harmless to the human body and self-purified through the decomposition of organic matters, is prepared in mass production at the room temperature through a simply synthesis method. The method includes the steps of (a) mixing a titanium precursor and a surfactant in a solvent and performing a sol-gel reaction at a room temperature; (b) maturing a reactant obtained through the sol-gel reaction at the room temperature; (c) filtering the matured reactant and washing the matured reactant; and (d) drying the washed reactant to obtain titanium dioxide having nanopores.

Abstract: The present invention relates to a method for preparing anatase-type titanium dioxide (TiO2) nanoparticles, the method comprising the steps of: uniformly mixing titanium n-butoxide and cetyltrimethyl ammonium salt (CTAS) in water; subjecting the mixture to hydrothermal treatment at a temperature of 60˜120° C.; and collecting anatase-type titanium dioxide nanoparticles produced by the hydrothermal treatment and drying the collected nanoparticles. According to the present invention, anatase-type titanium dioxide nanoparticles having excellent crystallinity can be easily prepared in large amounts by a simple process without needing heat treatment.

Abstract: Disclosed herein is a portable folding type hairstyling tool. The hairstyling tool includes a casing unit which also serves as a handle, and a hairstyling unit which is inserted into or unfolded from the casing unit to be used by pivoting. The hairstyling unit includes an electric heating part for applying heat to the hair, and the casing unit includes a power source. The hairstyling unit has a rotary switch around a hinge part, thus allowing power to be supplied to the electric heating part by a power source only when the hairstyling unit is unfolded from the casing unit.

Abstract: The present invention provides a peptide comprising an amino acid sequence of SEQ ID NO: 1, a variant thereof and a pharmaceutically acceptable salt thereof. A novel peptide of the present invention, a variant thereof and a pharmaceutically acceptable salt thereof are effective for treating and/or preventing degenerative disc diseases, treating body organ fibrosis, treating cancer and/or treating glomerulosclerosis, and are effective for the inhibition of TGF-beta1 signaling.
