The present invention provides an abrasive treatment technique capable of planarizing at an extremely high rate silicon carbide, which is thermally and chemically extremely stable and for which it is extremely difficult to efficiently perform an abrasive treatment. The present invention is a polishing slurry for silicon carbide wherein the polishing slurry includes a suspension liquid in which the pH thereof is 6.5 or more and manganese dioxide particles are suspended. The polishing slurry for silicon carbide is preferably a suspension in which manganese dioxide particles are suspended in an aqueous solution allowed to have a redox potential falling in a range enabling manganese to be present as manganese dioxide. The redox potential V of the polishing slurry preferably falls within the range specified by the following formula representing a relation between V and pH, pH being a variable: 1.014 - 0.591 pH ‰¤ V ‰¤ 1.620 - 0.0743 pH

摘要:
The present invention addresses the problem of identifying a biomarker of renal failure, said biomarker being available from urine or blood, and fluctuating from an early stage than glomerular filtration rate and serum creatinine level, and thus developing a technique for diagnosing early stage kidney failure. A method for analyzing the blood, plasma, serum or urine of a renal failure suspected subject comprises a step of measuring the concentration of a pair of D-form and L-form of at least one amino acid selected from the amino acid group consisting of [D-serine] and [L-serine], etc., contained in the blood, plasma, serum or urine of the subject, and calculating, as an pathological index of the subject, the ratio of the D-form concentration to the L-form concentration or the percentage of the D-form concentration relative to the total concentration of the D-form and L-form.
摘要:
[Problem to be Solved] To develop a technique in which NK cells having a high cytotoxic activity can be prepared with high purity from hematopoietic precursor cells without using a serum or feeder cells of an animal. [Solution] A method for expanding NK cells includes the steps of expanding hematopoietic precursor cells under a single culturing condition using a medium supplemented with IL-15, SCF, IL-7 and Flt3L, and differentially inducing the cells obtained in the expanding step into NK cells under a culturing condition using a medium supplemented with IL-2. A pharmaceutical composition contains the NK cells prepared by the method for expanding NK cells of the present invention. The pharmaceutical composition of the present invention is used for treating an infectious disease and/or a cancer.
