  • Publication number: 20240408140
    Abstract: The present invention relates to enhancing the anticancer function of a natural killer (NK) cell through the regulation of an antioxidant mechanism and confirms that, in comparison to a conventional NK cell, anticancer activity is enhanced in an NK cell having increased antioxidant activity due to the removal of the keap 1 gene or due to having been cultured in a medium containing an antioxidant material, and can thus be useful as a composition for preventing, treating, or alleviating cancer.

  • Patent number: 10976614
    Abstract: A method of manufacturing a stretched display panel includes: cutting the TFT substrate to a desired size; cutting the color filter substrate; forming an open-circuit line for open-circuiting a portion defined between a horizontal pixel line that is located at an end of the TFT substrate and another horizontal pixel line adjacent thereto in order to prevent electrical noise due to the horizontal pixel lines being introduced into the end of the TFT substrate exposed from the pixel exposure portion; and forming a reinforcement seal for covering the pixel exposure portion using a reinforcement material in order to prevent occurrence of short circuit due to introduction of foreign matter into a gap defined between the horizontal pixel line and the other horizontal pixel line and at the same time to increase rigidity of the pixel exposure portion.

  • Patent number: 10611858
    Abstract: According to the present invention, there is provided a method for preparing low molecular weight amorphous polypropylene. In contrast to the prior art in which amorphous polypropylene is prepared by injecting an internal donor and an external donor upon preparing a primary catalyst, the present invention enables easier preparation of low molecular weight amorphous polypropylene and a copolymer thereof by simply mixing a primary catalyst with an alkylaluminum-based co-catalyst without injecting an internal donor, upon preparing a primary catalyst, and an external donor, upon polymerization. According to the present invention, the primary catalyst has superior reactivity with hydrogen, as chain transfer agent, allowing for preparation of low molecular weight amorphous polypropylene even under low hydrogen pressures and low-pressure driving conditions.
