Patent number: 12343434Abstract: The disclosure provides a hybrid membrane camouflaged nanomedicine loaded with oxidative phosphorylation inhibitor and preparation method thereof. The nanomedicine comprises an inner core and an outer shell coated on the periphery of the inner core. The inner core is a ROS-responsive drug-loaded nanoparticle, and the drug loaded by the ROS-responsive nanocarrier is an oxidative phosphorylation inhibitor. The outer shell is a hybrid membrane of mitochondrial membrane and cancer cell membrane. The nanomedicines can cross the BBB and reach tumor sites by the homologous targeting of cancer cell membrane, and then they can homologously target and enter mitochondria by the mitochondrial membrane. Subsequently, under the high-level ROS environment of the mitochondria, the ROS responsive drug-loaded nanoparticle releases the oxidative phosphorylation inhibitor due to the swell and degradation of the inner core, so that the safe and efficient targeted GBM therapy is achieved.Type: GrantFiled: May 7, 2022Date of Patent: July 1, 2025Assignee: Henan UniversityInventors: Yan Zou, Yajing Sun, Bingyang Shi, Meng Zheng, Mingcong Hao

Publication number: 20250117959Abstract: Multiple predictions about the position of an object during a time period may each indicate the position of the object at a respective time during the time period. Respective validity indications corresponding to the multiple predictions may each indicate an accuracy of the corresponding prediction. Whether a change has occurred in a distribution of the predictions from a first subset of predictions to a second subset of predictions during the time period may be determined. If the change has occurred, a prediction from the first subset of predictions or the second subset of predictions may be selected, based on the validity of the predictions and/or the detection of a motion, as a best indication of the position of the object.Type: ApplicationFiled: October 4, 2023Publication date: April 10, 2025Applicant: Shanghai United Imaging Intelligence Co., Ltd.Inventors: Benjamin Planche, Ziyan Wu, Meng Zheng, Zhongpai Gao, Abhishek Sharma
