  • Patent number: 8563711
    Abstract: The present invention relates to a nucleic acid aptamer which can specifically recognize and bind to pancreatic cancer cells or tissues. The nucleic acid aptamer can bind specifically only to pancreatic cancer cells or tissues without binding to normal pancreatic cancer tissue, and thus can be effectively used as a composition for diagnosing and treating pancreatic cancer. In addition, the nucleic acid aptamer can detect not only the terminal pancreatic cancer cell line Capan-1, but also the early pancreatic cancer cell line Panc-1, and thus can be used for early diagnosis of pancreatic cancer, thereby contributing to increasing the survival rate of pancreatic cancer patients.

    Abstract: A method of making Y-type hexagonal ferrite and an antenna using the same are provided. Y-type hexagonal ferrite includes a base ferrite composed of iron oxide, barium carbonate and cobalt oxide, and silicate glass ranging from 0.5 to 5 weight percent added to 100 weight percent of base ferrite. An antenna apparatus includes a magnetic carrier and an antenna pattern formed thereon. The magnetic carrier is formed of such Y-type hexagonal ferrite, and the antenna pattern resonates in a specific frequency band when electric power is supplied. To fabricate the Y-type hexagonal ferrite, a calcination process is performed in which iron oxide, barium carbonate and cobalt oxide are combined into base ferrite at a given calcination temperature after being mixed. A sintering process is performed to sinter the base ferrite and the silicate glass at a given sintering temperature which is lower than the calcination temperature after adding the silicate glass to the base ferrite.
