Method of preparing iodine seed for treating eye disease or cancer, and iodine seed prepared thereby
Patent number: 9421282Abstract: The present invention provides a technique for adsorbing I-125 on a support for treating cancer and a method of preparing an I-125 seed using the same. Since a method of preparing iodine according to the present invention uses an intermediate having phosphate-based, oxalate-based, or arsenate-based anions introduced thereinto, the intermediate has a substitution effect of iodine 3 to 5 times higher than that of a typically used intermediate having chlorine anions introduced thereinto. According to the substitution effect, control of a radiation dose may be possible during the manufacturing of an iodine seed and an iodine seed may be prepared within a shorter period of time. Also, since an amount of residual radioactive iodine may be decreased as a result of a large amount of adsorption, an amount of radioactive iodine (I-125) waste may be decreased, and the effect thereof may be also high environmentally.Type: GrantFiled: February 12, 2013Date of Patent: August 23, 2016Assignee: Korea Atomic Energy Research InstituteInventors: Kang Hyuk Choi, Kwang Jae Son, Jin-Hee Lee, Sung-Soo Nam, Sun Ju Choi -

The treating can involve ion-exchanging ionic polymeric membrane foulants with non-fouling soluble ionic species that can be removed by polymeric membrane.Type: ApplicationFiled: May 8, 2014Publication date: February 5, 2015Inventors: Brian C. Speirs, Bruce K. Bartlett, Amitava Sarkar, Olusola B. Adeyinka

Publication number: 20150034556Abstract: A method and apparatus for removing soluble silica efficiently from accompanied water, produced from wells containing calcium ion, soluble silica, and sulfate ion, and not clogging a reverse osmosis membrane in the reverse osmosis membrane treatment process after that, includes adding a magnesium salt to mix with the accompanied water under alkaline conditions to produce insoluble silica and calcium sulfate. A microfiltration (MF) membrane treatment process includes treating a first reaction solution obtained in said magnesium salt adding process, with a microfiltration membrane to separate insolubilized silica and calcium sulfate by filtration. An acid adding process includes adding an acid to and mixing with filtrate obtained in the MF membrane treatment process to render a pH value of the filtrate on the range from 5 to 9 and a negative Langeliar saturation index.Type: ApplicationFiled: October 14, 2014Publication date: February 5, 2015Applicant: JFE ENGINEERING CORPORATIONInventors: Shigeki Fujiwara, Eri Watanabe, Yohei Tomida, Koji Fuchigami, Takeshi Tsuji, Yasuhiro Minamizato, Yasuto Ando, Yoshitaka Moriyama

Publication number: 20150027950Abstract: A method is described to treat atherosclerosis by extracorporeally treating a patient's blood. A patient's blood is treated extracorporeally using a moiety that targets an antigen in the blood. The moiety facilitates removal of the blood antigen. The cleansed blood is then returned to the patient.Type: ApplicationFiled: March 19, 2013Publication date: January 29, 2015Inventor: Mitchell S. Felder

Publication number: 20150027949Abstract: A method for removing nitrate ions from a solution is presented. The method includes providing a polymer comprising a protonated amine moiety and an anion derived from an acid having a pKa value greater than about 1. The method further includes contacting the polymer with the solution to bind at least a portion of the nitrate ions in the solution with the polymer, and form a polymer-nitrate complex. The method furthermore includes separating at least a portion of the polymer-nitrate complex from the solution.Type: ApplicationFiled: July 26, 2013Publication date: January 29, 2015Applicant: General Electric CompanyInventors: Hongchen Dong, Larry Neil Lewis, Stephen Robert Vasconcellos
