  • Patent number: 10596095
    Abstract: A method for moisturizing skin using P-113 peptide, which comprises administering to the skin of a subject a composition containing a P-113 peptide, wherein the P-113 peptide comprises the sequence of SEQ ID NO: 1. P-113 peptide is hypoallergenic and non-cytotoxic, which means it does not cause harms or allergies to the skin and can be used as an ingredient of cosmetic products. The P-113 peptide fragment has moisture absorption and moisture retention effects, therefore it can be formulated with other ingredients of moisturizing cosmetic products, enhancing the moisturizing effect of other moisturizing ingredients. In addition, the P-113 peptide fragment is capable of inhibiting the production of MMP-9 and thus decreases collagen degradation, thereby achieving the anti-wrinkle and anti-aging effects. The cosmetic disclosed herein comprises not only the peptide, but also active ingredients of cosmetic products and essence liquid formulations.

  • Publication number: 20100305152
    Abstract: The shikimate pathway links metabolism of carbohydrates to biosynthesis of aromatic compounds, which is an attractive target for the rational drug and herbicide design because it is essential in algae, higher plants, bacteria, and fungi, but absent from mammals. Thus, the present invention provides a method of inhibiting the growth of bacteria or fungi, especially Helicobacter pylori, through inhibiting enzymes in the shikimate pathway.

  • Patent number: 7812431
    Abstract: A leadframe includes a die pad and a plurality of leads corresponding to the die pad. The die pad for supporting a die is formed with a plurality of sides, each of the sides having at least one recess portion and at least one protrusion portion. The leads are substantially coplanar to the die pad. The leads include a plurality of first leads and a plurality of second leads. The first leads extend into the recess portions respectively, and the second leads are aligned with the protrusion portions. The length of the first leads is greater than that of the second leads. The length of wires electrically connecting the die to the leads or the die pad can be adjusted by the sides of the leadframe with the recess portion and the protrusion portion having a dimension corresponding to the leads, so as to save the manufacture cost of the leadframe.
