  • Publication number: 20230173268
    Abstract: A treatment device that shortens the time period until healing is determined even when a bone defect or a root apex lesion is generated in an apical area. The treatment device includes a file holder, a high-frequency signal generating circuit, and a control circuit. The file holder holds a file to be located in the site to be treated. The high-frequency signal generating circuit passes a high frequency current through the file. The control circuit controls a frequency of the high frequency current to be passed through the file from the high-frequency signal generating circuit. The control circuit controls the frequency of the high frequency current to be passed through the file within a range of 1.001 MHz to 11.700 MHz.

  • Publication number: 20230145941
    Abstract: Provided is a method for producing a high-purity aqueous lithium salt solution, the method allowing filtering aluminum phosphate in a short time. The method for producing a high-purity aqueous lithium salt solution includes: a step of adjusting the pH of a slurry containing a mixture of lithium phosphate and aluminum hydroxide obtained from a first aqueous lithium salt solution being a raw material to a range of 2 to 3 to obtain a precipitate of aluminum phosphate; a step of filtering off and removing the precipitate of aluminum phosphate to obtain a second aqueous lithium salt solution; and a step of purifying the second aqueous lithium salt solution to obtain a high-purity aqueous lithium salt solution.

  • Publication number: 20190353659
    Abstract: An object is to provide a test method for pancreatic cancer, and further to provide a test method for pancreatic cancer capable of detecting pancreatic cancer even at earlier stages. The objects are solved by a method for examining the likelihood of having pancreatic cancer, the method including (1) measuring the amount of at least one anti-carbohydrate antibody selected from the group consisting of anti-3-sialyllactose carbohydrate antibody and anti-(LN)3 carbohydrate antibody in a biological sample obtained from a subject, wherein the anti-3-sialyllactose carbohydrate antibody is an antibody capable of binding to a carbohydrate represented by Neu5Ac? (2?3) Gal? (1?4) Glc or an antibody recognizing the carbohydrate, and wherein the anti-(LN)3 carbohydrate antibody is an antibody capable of binding to a carbohydrate represented by Gal?1?3GlcNAc?1?3Gal?1?4GlcNAc or an antibody recognizing the carbohydrate.
