Abstract: The present invention is about bifunctional chelating agents (BCA) conjugated mannosyl human serum albumin (MSA) and its radioisotope labeled compounds for imaging immune system such as macrophages, Kupffer cells, reticuloendothelial system (RES), and lymphatic system. The present invention comprises BCA-MSA conjugates, their radiolabeled compounds, and kits for radiolabeing. The present invention improved radiolabeling procedure, showed higher lymphatic system uptake, and enabled image by positron emission tomography (PET).

Abstract: An active matrix LED display apparatus and a fabrication method thereof are provided. The active matrix LED display apparatus enables to miniaturize pixel by a formation of wiring on bottom layer and an assembly of each block through each eutectic layer into each transistor block receptor and/or each LED block receptor formed according to each color element unit, and to be embodied with high luminance, low power consumption, high reliability and superior optical property by assembling a transistor block having high electron mobility. And the fabricating method of the present invention enables to make efficiently an AM-LED display apparatus at room temperature in a short time by using different shapes of receptor and block depending on the function of a transistor and/or on the color of an LED.

Abstract: A pharmaceutical composition for the treatment of malignant tumors comprising a human p31comet gene encoding protein represented by SEQ ID NO: 3 or 4 as an effective component is provided. The pharmaceutical composition can suppress cancer cell growth, induce apoptosis and kill cells by overexpressing p31comet in the solid malignant tumor cells. Therefore, the pharmaceutical composition can be effectively used for gene therapy.

Abstract: The invention is directed to heterocyclic indene derivatives useful for ?-amyloid plaque imaging, their radiolabeled compounds and their preparation methods. The compounds of the invention are easily labeled with radioisotopes and have high affinities to ?-amyloid depositions, thus they facilitate diagnosis of Alzheimer's disease by imaging the distribution of ?-amyloid depositions.

Abstract: Benzylideneaniline derivatives of formula 1 wherein R1-R5 are independently selected from hydrogen, C1-C4 alkyl and F (at least one of them is F) and each R6-R10 are independently selected from hydrogen, C1-C4 alkyl, OH, OCH3, NH2, NHCH3 and N(CH3)2 (at least one of them is OH, OCH3, NH2, NHCH3 or N(CH3)2) are disclosed. Benzylideneaniline derivatives according to the present invention have high affinity to ?-amyloid plaques. Thus, they can cross the blood-brain-barrier (BBB) and bind to ?-amyloid plaques after administration into the body, making them useful for treatment, prevention, or imaging of Alzheimer's disease.

Abstract: The present invention relates to a novel diaminedithiol derivative or a pharmaceutically acceptable salt thereof; radiorhenium or radiotechneticum complex thereof; a composition for treating liver cancer comprising the radiorhenium complex and lipiodol; and, a preparative kit of the composition for treating liver cancer. In the composition according to the invention, the diaminedithiol derivative is a novel compound in which long chain alkyl groups were introduced to diaminedithiol, capable of forming a radiorhenium or radiotechnetium complex thereof with an ease and leading to stronger van der Waals bonds with lipiodol. As a result, the complex becomes more stable in a medium, lipiodol, whereby the composition of the invention exhibits a high accumulation rate in liver cancer tissue when injected via hepatic artery, thereby capable of achieving an efficient treatment of liver cancer.
