摘要:
An anode composition for a lithium secondary battery is provided. The anode composition comprises an anode active material, a conductive material, and an acrylonitrile-acrylic acid copolymer with a high molecular weight as a binder. The acrylonitrile-acrylic acid copolymer has a molar ratio of acrylonitrile to acrylic acid of 1:0.01-2. Further provided are a method for preparing the anode composition and a lithium secondary battery using the anode composition. The binder has improved resistance to an electrolyte solution due to its enhanced adhesive strength. In addition, the use of the anode composition prevents the active material layer from being peeled off or separated from a current collector during charge and discharge to achieve improved capacity and cycle life characteristics of the battery.

摘要:
The present invention relates to a biomarker for gastric cancer, CST1 (cysteine proteinase inhibitor, type 2 family), DCC1 (Defective in sister chromatid cohesion homolog 1), IFITM1 (interferon induced transmembrane protein 1) or MELK (maternal embryonic leucine zipper kinase). More particularly, the present invention relates to a diagnostic composition for gastric cancer comprising an agent measuring the expression level of CST1, DCC1, IFITM1 or MELK, a kit comprising the composition, a method for detecting the marker, and a method for screening a therapeutic agent for gastric cancer using the marker.
摘要:
The present invention relates to a method for detecting a colon cancer in a human, comprising the steps of: (a) providing a biological sample from the human; and (b) detecting the level of a ATAD2 nucleic acid or a ATAD2 protein in the biological sample, relative to the level of the ATAD2 nucleic acid or the ATAD2 protein in a control sample from a normal human, wherein an increased level of the ATAD2 nucleic acid or the ATAD2 protein in the biological sample compared to the control sample indicates that the human has the colon cancer. The biomarker of this invention was identified using normal colon tissue, colon cancer tissue and metastatic cancer tissue derived from a colon cancer patient. Therefore, the accuracy and reliability of the present biomarker for colon cancer and/or metastasis are much more significantly improved. In addition, the biomarker of this invention permits to identify and predict colon cancer or metastasis in an accurate manner.
