  • Publication number: 20210093678
    Abstract: The present invention relates to an Agathobaculum sp. strain having prophylactic or therapeutic effects on autism spectrum disorders, and use thereof. When the intestinal microorganism Agathobaculum sp. strain of the present invention was orally administered to valproic acid (VPA)-induced autism model mice and BTBR autism model mice, the effects of remarkably improving autism spectrum disorders including repetitive behaviors, hyperactivity, social deficiency and cognitive/memory dysfunction of the mice were observed, as compared with a non-treated control. Accordingly, it may be usefully applied to foods, drugs, or feeds for preventing or treating autism spectrum disorders, and thus is very useful in the relevant industries.

  • Publication number: 20190314425
    Abstract: The present disclosure relates to an Akkermansia muciniphila strain having a prophylactic or therapeutic effect on a degenerative brain disease and uses thereof. Since the Akkermansia muciniphila strain, the intestinal microorganism of the present disclosure, shows an effect of improving movement control and cognitive abilities as well as memory in an animal model having a degenerative brain disease such as Parkinson's disease and Alzheimer's disease, it can be useful in the prevention or treatment of brain diseases including Alzheimer's disease, Parkinson's disease, mild cognitive impairment, etc. In addition, it was confirmed in the present disclosure that compared to the Akkermansia muciniphila strain cultured in a mucin-containing medium, that cultured in a mucin-free medium showed a remarkable effect of improving hyperlipidemia, fatty liver, obesity, and hyperglycemia induced in a mouse model by high-fat diet when administered orally (in vivo).

  • Patent number: 9464737
    Abstract: Proposed are an eco-friendly high pressure hose fabric and an eco-friendly high pressure hose using the same. The eco-friendly high pressure hose fabric includes a textile woven from a polypropylene-based fiber, a first coating layer formed on one surface of the textile, a second coating layer formed on the other surface of the textile to extend longer than the length of the textile, a resin adhesive layer formed over the entirety of the top surface of the first coating layer and the top surface of the second coating layer extending longer than the length of the textile, and a film layer formed on the top surface of the resin adhesive layer to correspond to the length of the second coating layer. Ends of the second coating layer, the resin adhesive layer and the film layer, which extend longer than the length of the textile and are stacked on one another, form an extended portion of the fabric.

  • Publication number: 20060205305
    Abstract: A fabric structure and its manufacturing method are disclosed. The fabric structure is weaved by wefts and warps which are crossed with each other, and each of wefts and warps has a double ply structure in which yarns thereof are contacted in a length direction. The fabric structure gives more excellent mechanical strength and better flexibility than a conventional one. Relatively thicker reinforced weft and warp are repeatedly inserted and weaved among common wefts and warps so as to form repeatedly protruded rectangular patterns on the surface of the fabric structure. The patterns increase a surface friction, thereby preventing accidents caused by slippery of the surface of the fabric structure.

  • Publication number: 20030064647
    Abstract: The present invention relates to a tarpaulin using resin composition for press-coating and a preparation method thereof. The tarpaulin comprises a polypropylene woven fabric layer prepared by weaving polypropylene multifilament yarn; and a resin composition layer which is press-coated on either or both sides of said polypropylene woven fabric layer, wherein the resin composition is obtained by melt-kneading ethylene-propylene copolymer and ethylene-octene random copolymer or styrene-ethylene-butene block copolymer. The tarpaulin of the present invention as obtained by using a resin composition for press-coating is flexible, light and recyclable. Because the tarpaulin of the present invention has an excellent mechanical strength, it is suitable for use as an industrial material.
