Abstract: A sprayed coating having a multilayer structure including a lower layer made a sprayed coating containing a rare earth oxide, and a surface layer made of another sprayed coating containing a rare earth fluoride and/or a rare earth oxyfluoride, the multilayered sprayed coating having a volume resistivity at 23° C. and a volume resistivity at 200° C., the volume resistivity at 23° C. being 1×109 to 1×1012 ?·cm, and a temperature index of the volume resistivities defined by the ratio of the volume resistivity at 200° C. to the volume resistivity at 23° C. being 0.1 to 10.

Abstract: An object of the present invention is to provide a method for detecting a colorectal tumor, and particularly advanced adenoma and early cancer, by using a component contained in stool as an indicator. Provided is a method for detecting colorectal tumor using a marker gene, comprising: (A) a step for extracting RNA contained in stool collected from a subject, (B) a step for measuring the amount of RNA derived from a marker gene present in the RNA obtained in step (A), and (C) a step for comparing the amount of RNA derived from the marker gene measured in step (B) with preset threshold values for each type of marker gene; wherein, the marker gene is creatine kinase B (CKB) gene.

Abstract: An object of the present invention is to provide a method of detecting an inflammatory bowel disease, and particularly ulcerative colitis, by using a component contained in fecal matter as an indicator. Namely, the present invention provides a method for detecting ulcerative colitis comprising: (A) a step of extracting RNA contained in fecal matter collected from a subject, (B) a step of measuring the amount of RNA derived from a marker gene in the RNA obtained in step (A), and (C) a step of comparing the amount of the RNA derived from the marker gene measured in step (B) with a preset threshold value, wherein the marker gene is one or more types of genes selected from the group consisting of COX-2 gene, B2M gene, MMP-7 gene, Snail gene, CD45 gene and CEA gene.
