Publication number: 20240145426Abstract: A bonding structure and a power device. The bonding structure includes a first power unit and at least two bonding wires. At least one end of the bonding wire is connected to the first power unit through bonding. Projections that are of lead paths of the at least two bonding wires and that are on a preset plane have at least one intersection point. Spatial cross wire bonding is performed on the bonding wires, so that lead paths of the bonding wires form an angle with each other, thereby weakening electromagnetic force between the bonding wires.

Publication number: 20220175957Abstract: CNS metastases are a major cause of cancer deaths with few therapeutic options for treatment. Monoclonal anti-body-based therapy is one of the most successful therapeutic strategies for cancer; however, its efficacy is limited against CNS metastases due to insufficient CNS delivery. Here, we show significantly improved antibody delivery to the CNS using novel timed-release nanocapsules that encapsulate individual antibodies within a crosslinked phosphorylcholine polymer and gradually release cargo through hydrolysable crosslinkers. A single course of rituximab (RTX) nanocapsule treatment elevates RTX levels in the CNS by nearly 10-fold compared to native RTX. We improved control of CNS metastases in a murine xenograft model of non-Hodgkin lymphoma; moreover, using a xenograft humanized BLT mouse model, lymphomas were eliminated with a single course of RTX nanocapsule treatment. This approach is useful for treatment of cancers with CNS metastases and is generalizable for delivery of any antibody to the CNS.Type: ApplicationFiled: February 19, 2020Publication date: June 9, 2022Applicant: The Regents of the University of CaliforniaInventors: Masakazu Kamata, Irvin S.Y.

Patent number: 11253483Abstract: A method for intracellular delivery of single proteins or other cargo molecules by encapsulation within nanocapsules formed by interfacial polymerization of one or more types of monomers and selected protease cleavable cross-linkers is provided. The thin positively charged capsules are readily brought into the cytosol of target cells by endocytosis. The capsules are degraded by the action of endogenous proteases or co-delivered proteases on the cross-linkers releasing the functional cargo unaltered. The cross-linkers can be adapted to be cleavable by specific enzymes selected from available intracellular enzymes within the target cell or co-delivered or self-cleaving when the cargo itself is a protease. The nanocapsules produced by the methods have been shown to have long-term stability, high cell penetration capability, low toxicity and efficient protease-modulated specific degradability without affecting cargo protein function.Type: GrantFiled: August 26, 2019Date of Patent: February 22, 2022Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Yi Tang, Zhen Gu, Yunfeng Lu, Ming Yan, Anuradha Biswas, Guoping Fan

Publication number: 20200405823Abstract: Alcohol intoxication causes serious diseases, whereas current treatments are mostly supportive and unable to remove alcohol efficiently. Upon alcohol consumption, alcohol is sequentially oxidized to acetaldehyde and acetate by the endogenous alcohol dehydrogenase and aldehyde dehydrogenase, respectively. We disclose a hepatocyte-mimicking antidote for alcohol intoxication through the co-delivery of the nanocapsules of alcohol oxidase (AOx), catalase (CAT), and aldehyde dehydrogenase (ALDH) to the liver, where AOx and CAT catalyze the oxidation of alcohol to acetaldehyde, while ALDH catalyzes the oxidation of acetaldehyde to acetate. Administered to alcohol-intoxicated mice, the antidote rapidly accumulates in the liver and enables a significant reduction of the blood alcohol concentration. Moreover, blood acetaldehyde concentration is maintained at an extremely low level, significantly contributing to liver protection.Type: ApplicationFiled: March 29, 2019Publication date: December 31, 2020Applicant: The Regents of the University of CaliforniaInventors: Yunfeng Lu, Cheng Ji, Duo Xu, Hui Han

Publication number: 20200323786Abstract: Growth factors are of great potential in regenerative medicine. However, their clinical applications are largely limited in by short in vivo half-lives and a narrow therapeutic window. Thus, a robust controlled release system remains an unmet medical need for growth-factor-based therapies. A nanoscale controlled release system (degradable protein nanocapsule) is provided via in-situ polymerization on growth factor. The release rate can be finely tuned by engineering the surface polymer composition. Improved therapeutic outcomes are achieved with the growth factor nanocapsules, as illustrated in spinal cord fusion mediated by bone morphogenetic protein-2 (BMP-2) nanocapsules.Type: ApplicationFiled: May 24, 2017Publication date: October 15, 2020Applicants: THE REGENTS OF THE UNIVERSITY OF CALIFORNIA, THE UNIVERSITY OF SOUTHERN CALIFORNIA, TIANJIN UNIVERSITYInventors: Yunfeng Lu, Jeffrey C.
