Patent number: 11599694Abstract: A method for assessing fatigue damage and a fatigue life based on a crystal plastic welding process model. According to the new method, consideration is given to the effects of the crystal slip system and the polycrystal plastic strain on the welding process performance of the material. A welding process damage and fatigue life assessment model is established on the mesoscopic scale. The effect of microscopic characterizations of materials on the welding process performance, as well as on the fatigue damage and life of welded joints, can be studied from the mesoscopic point of view. The relationship between the welding process and the evolution of the material performance can be determined by the macro-mesoscopic coupling calculation model to further determine the effect and degree of welding processes on the fatigue damage and life of materials.Type: GrantFiled: May 15, 2020Date of Patent: March 7, 2023Assignee: SICHUAN UNIVERSITYInventors: Qingyuan Wang, Hong Zhang, Yongjie Liu, Chong Wang, Lang Li, Chao He

Publication number: 20120088247Abstract: A pathway for the metabolism of tamoxifen is identified including the activity of at least 2 different isoforms of UGY2B7. This pathway includes isozymes of CYP3A which convert tamoxifen (TAM) to N-desmethyl-TAM, which is then converted to endoxifen by the action of CYP2D6. Once formed, endoxifen may be degraded by at least one isozyme of UGT2B7. Patients that have highly active isoforms of CYP2D6 and slow acting isoforms of UGT2B7 accumulate high levels of endoxifen and are good candidates for treatment with tamoxifen. Also disclosed are methods for screening patients with a high likelihood of benefiting from treatment with tamoxifen. These methods include testing patients for various alleles of genes known to be involved in tamoxifen metabolism and treating patients accordingly.Type: ApplicationFiled: February 23, 2010Publication date: April 12, 2012Applicant: Indian University Research & Technology CorporatioInventors: David Flockhart, Zeruesenay Desta, Anne Nguyen, Todd Skaar, Lang Li
