Patent number: 11104728Abstract: The present invention relates to an anti-EMAP II antibody or an antigen-binding fragment thereof, a nucleic acid molecule for coding the same, or a preparation method thereof. Also, the present invention provides a method for using the anti-EMAP II antibody or the antigen-binding fragment thereof in preventing, treating or diagnosing EMAP II-mediated diseases, for example, TNF-?-mediated disease or Alzheimer's disease. Furthermore, the present invention provides a method for using the anti-EMAP II antibody or the antigen-binding fragment thereof in detecting or quantifying an EMAP II antigen. The antibody of the present invention may exhibit a more improved antigen-binding capacity compared to existing anti-EMAP antibodies and may treat the TNF-?-mediated disease more effectively.Type: GrantFiled: March 27, 2018Date of Patent: August 31, 2021Assignee: HUB Biotech Co., Ltd.Inventors: Sang Gyu Park, Gook-Jin Kang

Patent number: 11099191Abstract: The purpose of the present invention is to provide: a method for predicting the prognosis for kidney disease for a subject on the basis of the amount of D- and L-amino acids, from a blood sample; and an analysis system that determines prognosis predictions. This purpose is achieved by using at least one amino acid to predict the prognosis for kidney disease, said amino acid being selected from the group consisting of D-serine, D-asparagine, D-proline, D-alanine, D-leucine, D-lysine, D-allo-isoleucine, L-glutamic acid, L-alanine, L-tryptophan, and L-asparagine.Type: GrantFiled: May 17, 2017Date of Patent: August 24, 2021Assignees: Osaka University, Kagami Inc.Inventors: Yoshitaka Isaka, Tomonori Kimura, Keiko Yasuda, Kenji Hamase, Masashi Mita

Patent number: 11099145Abstract: Systems and methods electronic barcoding of particles. The methods comprise: performing operations by a spin coater to spin coat a single layer of particles onto a substrate; performing operations by a heat applicator to apply heat to the substrate so as to evaporate a liquid; and performing operations by at least one material depositor to transform the particles into Electronically Barcoded Particles (“EBPs”). EBPs are fabricated by: coating a portion of each said particle of the particles with a first conductive layer; depositing an insulative layer on the first conductive layer; and/or depositing a second conductive layer on the insulative layer so as to form a parallel plate capacitor on the particle. The parallel plate capacitor is tuned so that the particle has a capacitance that is different than the capacitances of other ones of the electronically barcoded particles.Type: GrantFiled: January 12, 2017Date of Patent: August 24, 2021Assignee: RUTGERS, THE STATE UNIVERSITY OF NEW JERSEYInventor: Mehdi Javanmard

Patent number: 11079376Abstract: The optical analyte detector is a photonic detector that uses a measured wavelength shift to determine the presence of an analyte. An open cell is formed in an optical layer for receiving a sample to be analyzed. A transition metal dichalcogenide monolayer defines a bottom wall of the open cell, and the transition metal dichalcogenide monolayer is formed directly above a microring resonator. A waveguide is positioned adjacent to the open cell, and is spaced apart therefrom by a gap. The waveguide is coupled to the microring resonator, and the transition metal dichalcogenide monolayer is functionalized with an adsorbed layer for detection of a specific analyte. Molecular binding takes place if a sample of the analyte contacts the adsorbed layer, which induces a wavelength shift in light transmitted through the waveguide. The presence of this measured wavelength shift indicates positive detection of the analyte.Type: GrantFiled: November 12, 2020Date of Patent: August 3, 2021Assignee: UNITED ARAB EMIRATES UNIVERSITYInventor: Adel Najar
