Abstract: A light reflecting body includes a base containing a resin material and a calcium carbonate and includes a metal layer on the surface of the base. The resin material is selected from a polyester resin composition, a polyarylate resin composition, and a mixed resin composition thereof. The calcium carbonate has a BET specific surface area of 1 to 15 m2/g, a pore distribution curve determined by mercury porosimetry that the top of a peak representing interparticle void size is in a pore size range of 0.1 to 1.0 ?m, a particle size distribution determined by using an electron microscope that the proportion of particles having a particle size of 0.1 ?m or less is 10% or less of the calcium carbonate, and the residue on a sieve having a mesh size of 45 ?m after wet sieving of the calcium carbonate is 0.1% or less.

Abstract: The present invention aims to provide a nucleic acid molecule having improved stability in serum and capable of exhibiting a gene expression regulation function after transfer into the cell. A cyclic nucleic acid molecule represented by the following formula (A): wherein each symbol is as described in the DESCRIPTION can be synthesized easily at a low cost, and can inhibit the translation of a protein encoded by the gene.

Abstract: A method of readily detecting or differentiating rheumatoid arthritis, which has so far been diagnosed in a comprehensive manner based on various tests and clinical symptoms, and a method of readily and objectively estimating the stage of disease and the degree of dysfunction with regard to rheumatoid arthritis are provided. The detection and differentiation of rheumatoid arthritis are performed by measuring the levels of L-PGDS in a sample such as a body fluid such that the measurement value is used as an index. Further, the stage of disease or the degree of dysfunction of a rheumatoid arthritis patient is determined using the measurement value as an index.
