  • Publication number: 20210328229
    Abstract: Proposed is an iridium alloy catalyst having reversible catalytic activity for an oxygen evolution reaction (OER), a hydrogen evolution reaction (HER), and a hydrogen oxidation reaction (HOR) by including an iridium alloy including iridium (Ir) and nickel (Ni). The iridium alloy catalyst according to the present disclosure is rapidly converted to an iridium alloy catalyst in an oxide form and an iridium alloy catalyst in a metallic form according to applied voltage by controlling its crystallinity. Thus, even in case an oxide layer is formed after the OER, the oxidation layer disappears during the HER and HOR and the properties of an iridium metal catalyst remain, thereby maintaining HER/HOR performance.

  • Publication number: 20210231669
    Abstract: The present invention relates to a method for diagnosing pancreatic cancer using methionyl-tRNA synthetase (MRS). When used as a pancreatic cancer marker, MRS has a significantly higher level of diagnostic accuracy than conventional pancreatic cancer markers such as CEA; thus, analyzing the expression status of methionyl-tRNA synthetase (MRS) in pancreatic cells has the effect of clearly determining the presence or absence of pancreatic cancer, and said effect is likewise exhibited even in the cells that have been determined to be atypical cells by a general staining technique, and thus can be very useful in the diagnosis of pancreatic cancer.

  • Publication number: 20200376003
    Abstract: The present invention relates to a gallstone solubilizing agent, comprising ursodeoxycholic acid (UDCA) or a pharmaceutically acceptable salt thereof; omega-3 fatty acid; and an excipient, the gallstone solubilizing agent resulting in a process which prevents cholesterol gallstones from being formed or causes cholesterol gallstones to be dissolved, a pharmaceutical composition comprising the same, and a health functional food composition comprising the same. A pharmaceutical composition prepared to have UDCA and omega-3 fatty acid at an optimal content ratio allows cholesterol to remain in a dissolved state without forming crystals, and thus results in a process which prevents cholesterol gallstones from being formed or causes cholesterol gallstones to be dissolved, thereby exhibiting increased effects of preventing or treating cholesterol gallstones.
