Patent number: 11680062Abstract: Disclosed are 3,4-methylenedioxyphenylimidazolylethanonexime ether derivatives, a preparation method and use thereof, and a drug for the treatment of Alzheimer's disease, which relates to the technical field of preparation of acetophenone oxime ether compounds. The (Z)-3,4-methylenedioxyphenylimidazolylethanonexime ether derivatives provided by the present disclosure show a significant effect on the inhibition of NO production, with an EC50 of 2.07-5.41 ?mol/L. Compared with the positive control group of quercetin (with an EC50 of 9.56 ?mol/L) and oxiconazole (with an EC50 of 13.5 ?mol/L), the inhibitory effect is stronger without significant cytotoxicity (cell viability >90%), which can be used to prepare drugs for the treatment of Alzheimer's disease.Type: GrantFiled: February 14, 2022Date of Patent: June 20, 2023Assignee: NORTHWEST A & F UNIVERSITYInventors: Jiangjiang Tang, Zhaoyuan Bian, Lanfang Huang, Bo Ren, Ping Xiang, Jinming Gao

Patent number: 8649577Abstract: A method uses a computer and software to measure bone density and structure of the proximal femur of the hip from a volumetric set of images containing pixels representing x-ray attenuation of the subject which are acquired with three-dimensional X-ray imaging devices. The method automatically locates anatomical markers of the hip without operator interaction, automatically positions regions of interest (ROIs) for measurement, automatically determines bone density measures of the ROIs, and automatically reports the results for individual subjects. Bone density measurements of ROIs include the integral bone of the total hip and neck as well as trabecular bone. The method automatically identifies a three-dimensional region-of-interest (ROI) volume which includes the hip, determines a three-dimensional coordinate system referenced to the anatomy of the subject, analyzes the ROI volume to identify voxels in the volume which satisfy defined criteria, and determines a measure of bone structure.Type: GrantFiled: November 27, 2009Date of Patent: February 11, 2014Assignee: Image Analysis, Inc.Inventors: Ben A.
