Abstract: The present disclosure relates to a Mitochondria-Associated endoplasmic reticulum Membrane (MAM)-specific fluorescence calcium sensor and the use thereof. The present disclosure can surmount the limitations of a conventional technique in that verification of calcium migration through MAM requires separate measurements of calcium ion concentrations within ER and mitochondria and situational explanations of the phenomena, and can directly measure concentrations in the paths through which calcium ions move to exclude influences on calcium ion changes through numerous different calcium ion channels existing in mitochondria, thereby providing a convenient and accurate MAM-specific calcium ion sensor.

Abstract: The present invention relates to a highly efficient aptamer complex comprising a branched DNA and an aptamer, and a pharmaceutical use thereof. More specifically, the aptamer complex of the present invention relates to a highly efficient aptamer complex including a Y-shaped DNA as the branched DNA and using vascular endothelial growth factor (VEGF) as a target molecule. The aptamer complex of the present invention and a pharmaceutical composition comprising the same as an active ingredient are expected to be widely used in the medical field since the binding efficiency with the target molecule is more remarkable than that of the conventional aptamer.

Abstract: An electronic device is disclosed. The electronic device comprises: a first plate including a first planar region facing a first direction; a second plate comprising a second planar region facing a second direction opposite to the first direction; a housing including a side member surrounding an inner space between the first plate and the second plate; a display disposed between the first plate and the second plate and viewed through the first plate; and an antenna module disposed between the display and the second plate and configured to emit electromagnetic waves to the outside of the housing. The antenna module comprises: an antenna substrate including a first surface facing the first plate, a second surface facing the second plate, and a third surface facing the inner surface of the side member; and a wireless communication circuit disposed on the first surface of the antenna substrate. The antenna substrate comprises: a first antenna adjacent to the first surface or formed on the first surface; a second antenna adjacent to the second surface or formed on the second surface; and a third antenna formed between the first antenna and the second antenna. The first antenna is formed at a first distance from the third surface, the second antenna is formed at a second distance from the third surface, and the third antenna may be formed at a third distance that is greater than the first distance and the second distance from the third surface. Various other embodiments inferred from the present specification are also possible.

Abstract: The present invention relates to a fluorene derivative or a pharmaceutically acceptable salt thereof, a preparation method therefor, and a pharmaceutical composition comprising the same as an effective ingredient for preventing or treating HCV-related disease. A fluorene derivative according to the present invention is identified to exhibit an antiviral performance against not only HCV, but also highly against HCV mutants, particularly double mutants and thus can be used in a pharmaceutical composition for prevention or treatment of HCV-caused liver disease, such as acute hepatitis C, chronic hepatitis C, liver cirrhosis, hepatocellular cancer, etc., particularly, liver disease caused by mutants of HCV. The derivative can be useful in a pharmaceutical composition for prevention or treatment of HCV-related liver disease by which the problem of resistant mutation against conventional therapeutic agents is solved.

Abstract: The present invention relates to a real-time voice recognition apparatus equipped with an application-specific integrated circuits (ASIC) chip and a smartphone, capable, by using one smartphone and one ASIC chip and without using a cloud computer, of assuring personal privacy, and, due to a short delay time, enabling real-time conversion of voice input signals into text for output. When one DRAM chip is optionally added to the real-time voice recognition apparatus, the number of neural network layers is increased thereby significantly improving accuracy of conversion of voice input signals into text.
