  • Patent number: 8878006
    Abstract: The present invention relates generally to the field of molecular biology and concerns a method for enhancing plant yield-related traits relative to control plants. More specifically, the present invention concerns a method for enhancing yield related traits in plants relative to control plants, by modulating, preferably increasing, expression in the roots of a plant, of a nucleic acid sequence encoding a 2-cysteine peroxiredoxin (2-Cys PRX); or by modulating expression of a nucleic acid encoding an ANN polypeptide in a plant. The present invention also concerns plants having modulated, preferably increased, expression in the roots, of a nucleic acid sequence encoding a 2-Cys PRX, or having modulated expression of a nucleic acid encoding an ANN polypeptide, which plants have enhanced yield-related traits relative to control plants. The invention also provides constructs useful in the methods of the invention.

  • Publication number: 20140100286
    Abstract: There is provided a composition including a veratric acid for preventing or treating inflammatory diseases. The veratric acid of the present invention has an excellent effect of inhibiting production of nitric oxide, an excellent activity of inhibiting production of IL-1? as a pro-inflammatory cytokine, and an excellent effect of inhibiting phosphorylation of MAPK, NF-?B, GSK-3?, and c-Raf in a macrophage cell stimulated by a stimulation factor that causes an inflammatory reaction. Thus, it can be used for development of medicines for treating inflammatory diseases which can be caused by excessive inflammatory reactions. Further, the veratric acid of the present invention does not induce toxicity to cells and is stable in the body. Thus, it can be used as a material of a health functional food capable of preventing or improving inflammatory diseases.

  • Patent number: 8585022
    Abstract: An apparatus for generating microbubbles in water from a mixed fluid in which a gas and a liquid are mixed. The apparatus includes a cylindrical body which includes an inlet coupled to a hose, an outlet, and a cylindrical space section defined therein. The diameter of the space section is greater than each diameter of the inlet and the outlet. An inner container member is fixed in the space section such that a tubular passage is formed. A circular first collision section is provided on the inner container member. The mixed fluid that has been introduced through the inlet collides against the first collision section and is thus stirred. An ā€œLā€ shaped second collision section is provided on the inner corner of the body adjacent to the outlet. The mixed fluid that has passed through the passage collides against the second collision section and is thus stirred.

  • Publication number: 20130020567
    Abstract: A thin film transistor may include a passivation layer formed of a metal-containing conductive material. The thin film transistor includes: a gate electrode; a gate insulating layer positioned on the gate electrode; a channel layer positioned on the gate insulating layer; a source electrode and a drain electrode which are in contact with the channel layer while being spaced apart from each other; and a passivation layer including a metal-containing conductive material and positioned on the channel layer while being spaced apart from each of the source electrode and the drain electrode. The passivation layer serves to prevent transmission of light, oxygen, water and/or impurities into the channel layer and to improve the electrical characteristics of the thin film transistor.

  • Publication number: 20020121858
    Abstract: The present invention relates to a short wavelength ZnO light emitting device and the manufacturing method thereof, which forms materials of p-type by doping Zn on InP, deposits a thin layer of ZnO on an upper surface of the doped layer and forms a p-n junction, thereby obtaining a stable crystal structure and enhances the effectiveness. The short wavelength ZnO light emitting device comprises a Zn doped InP layer of p-type formed by doping Zn on a substrate of InP and then replacing In with Zn; and a ZnO layer deposited on the Zn doped InP substrate whereby a forward bias voltage is applied to the doped InP and the ZnO layers, which are doped Zn, thereby obtaining a light emitting characteristic of short wavelength. A ZnO-based semiconductor light emitting device can be used as a blue and purple light source, and is expected to have more excellent characteristics in displays.
