Publication number: 20240077417Abstract: The disclosure relates to a non-dispersive infrared (NDIR) gas sensor which detects the concentration of gas with a simple structure and method by manufacturing an optical waveguide with a gas-permeable polymer material instead of a conventional cavity or chamber type. An optical signal travels through the optical waveguide of gas-permeable polymer by total internal reflection, and the gas naturally penetrates the optical waveguide without the use of separate inlet and outlet openings, so that the optical signal and gas particles come into contact with each other within the optical waveguide. Since the optical signal detected by a photodetector at the other end of the optical waveguide after traveling while contacting the gas particles has properties changed according to the concentration of the gas which they have contacted in the optical waveguide, it is possible to measure the concentration of a specific gas from the detected optical signal.Type: ApplicationFiled: July 11, 2023Publication date: March 7, 2024Applicant: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTEInventors: Jin Hwa RYU, Soocheol KIM, Hyunseok KIM, So Yung PARK, Hoe-Sung YANG, Kang Bok LEE, Kwang-Soo CHO, Kyu Won HAN

Patent number: 8916525Abstract: The present invention relates to TNFR2-TWEAKR fusion protein, more precisely to TNFR2-TWEAKR fusion protein acting as a double-antagonist to TNF-? and TWEAK, known as major causes of autoimmune arthritis which is one of autoimmune diseases. When the composition comprising TNFR2-TWEAKR fusion protein was treated to Th17 cells, the secretion of the inflammatory cytokine IL-17 was reduced but the secretion of the anti-inflammatory cytokine IL-10 generated in Treg cells was increased. Such effect of TNFR2-TWEAKR fusion protein was far greater than that of a single protein such as TNFR2-Fc or TWEAK-Fc. The TNFR2-TWEAKR fusion protein of the present invention has not only excellent treatment effect on arthritis in CIA mouse model not also excellent treatment effect on autoimmune rheumatoid arthritis by increasing the expression of Treg, the immune suppressive cells.Type: GrantFiled: March 18, 2011Date of Patent: December 23, 2014Assignees: Korea Research Institute of Bioscience and Biotechnology, Industry-Academic Cooperation Foundation, The Catholic University of KoreaInventors: Young Woo Park, Ki Won Jo, Srok Ho Yoo, Jung Yu, Dong Jin Kim, Sun-Ha Yoon, Eun Jung Song, Eun Kyung Lee, Jin Mi Oh, Kyu Won Cho, Mi La Cho, Ho Youn Kim, Mi Kyung Park, Hye Jwa Oh, Jin Sil Park, Yun Ju Woo, Jae Kyeong Byun, Jun Geol Ryu
