Patent number: 11971340Abstract: The present disclosure provides a method for predicting a lattice defect in a metal-organic framework (MOF) membrane. The method comprises acquiring a number n of a ligand during preparation of the MOF membrane, and acquiring a theoretical number m of connections formed between a core secondary building unit and a surrounding secondary building unit; setting a number of collisions of the ligand with the core secondary building unit and the surrounding secondary building unit; and calculating an expected value of a number of connections formed on lattices based on a collision probability, wherein the number of collisions is 1 or 2.Type: GrantFiled: October 31, 2023Date of Patent: April 30, 2024Assignee: NANJING TECH UNIVERSITYInventors: Gongping Liu, Guozhen Liu, Wanqin Jin

Publication number: 20200057062Abstract: A use of an enhancer of rudimentary homolog (ERH) or a fragment thereof, in the preparation of a reagent for monitoring drug efficacy for rheumatoid arthritis, is provided. 35 proteins as candidate ACPA-negative RA autoantigens, 8 proteins as candidate autoantigens for predicting disease activity, and 6 proteins as candidate autoantigens for predicting treatment effect were screened by hybridizing high density protein chips with RA serum. Of the 6 proteins as candidate autoantigens for predicting treatment effect, one autoantigen, ERH, can successfully determine the effect of drug treatment on RA, and the AUC for predicting efficacy may be up to 0.733.Type: ApplicationFiled: November 15, 2017Publication date: February 20, 2020Inventors: Xuan ZHANG, Wenxiu MO, Yongzhe LI, Chaojun HU, Guozhen LIU, Lijun WU
