Publication number: 20150072416Abstract: According to the present invention, when nicotinamide is added in a culture process for producing pluripotent stem cells from human differentiated cells, it can increase the efficiency of reprogramming and can significantly reduce the time required for induction of reprogramming. It was verified that nicotinamide inhibits the induction of senescence and oxidative stress in the reprogramming process and increases cell proliferation and mitochondrial activity to effectively improve culture conditions for induction of reprogramming. Particularly, the present invention will contribute to optimizing a process of producing induced pluripotent stem cells from a small amount of patient-specific somatic cells obtained from various sources, and thus it will significantly improve a process of developing clinically applicable personalized stem cell therapy agents and new drugs and will facilitate the practical application of these agents and drugs.Type: ApplicationFiled: April 26, 2013Publication date: March 12, 2015Applicant: Korea Research Institute of Bioscience and BiotechInventors: Yee Sook Cho, Myung Jin Son, Mi Young Son

Patent number: 8785015Abstract: Disclosed are an electrolyte for a secondary battery, and a secondary battery including the same, the electrolyte including an electrolyte salt; an electrolyte solvent; and a compound generating heat through oxidation at voltages higher than drive voltage of a cathode, wherein the compound can decompose or evaporate electrolyte components by oxidation heat, thereby causing gas generation. Also, the compound is included in an internal pressure increase accelerant for a battery. Upon overcharge, since a compound subjected to oxidation at voltages higher than normal drive voltage of a cathode generates heat, electrolyte components can be decomposed or evaporated, thereby generating gas by the oxidation heat. Accordingly, it is possible to operate a safety means of a battery, without using an internal pressure increasing material directly generating gas through oxidation at overcharge voltage as the electrolyte additive, and thus to improve the overcharge safety of a secondary battery.Type: GrantFiled: May 15, 2008Date of Patent: July 22, 2014Assignee: LG Chem, Ltd.Inventors: Mi Young Son, Jeong-Ju Cho, Hochun Lee, Joomi Jeon, Sunghoon Yu
