  • Publication number: 20180064766
    Abstract: The present invention relates to a composition for preventing or treating of colitis comprising Lactobacillus sakei K040706 as an active ingredient. More particularly, the present invention relates to a pharmaceutical composition or a food composition for preventing or treating colitis comprising Lactobacillus sakei K040706 (Accession No: KCCM11472P) as an active ingredient. Since Lactobacillus sakei K040706 of the present invention is capable of enhancing immune function such as increasing intestinal NO production ability and reducing the damage of intestinal tissue, Lactobacillus sakei K040706 may be useful for improving and treating colitis.

  • Patent number: 9536992
    Abstract: A method includes providing a semiconductor structure. The semiconductor structure includes a first transistor region, a second transistor region and a silicon dioxide layer on the first transistor region and the second transistor region. A layer of a high-k dielectric material is deposited on the silicon dioxide layer. A layer of a first metal is formed over the second transistor region. The layer of first metal does not cover the first transistor region. After the formation of the layer of the first metal, a layer of a second metal is deposited over the first transistor region and the second transistor region. A first annealing process is performed. The first annealing process initiates a scavenging reaction between the second metal and silicon dioxide from a portion of the silicon dioxide layer on the first transistor region. After the annealing process, a ferroelectric transistor dielectric is formed over the first transistor region.
