  • Patent number: 12357434
    Abstract: A maxilla holder includes a base plate and a connecting member. One end of the connecting member is connected with the base plate which extends along a pre-designed occlusal plane while the other end of the connecting member includes at least two supporting portions. With the supporting portions abutting against the cranium, the base plate is positioned so that the maxilla is located in a pre-planned position once it is moved onto the base plate.

  • Publication number: 20250135048
    Abstract: A fibroblast activation protein (FAP) compound or salt is provided with albumin dual-binding function. It is a new target FAP molecule, comprising a payload group, a linker group and a FAP binding group. The linker group has an architecture selected from four architectures to connect to the payload group and the FAP binding group to form the FAP compound. The target FAP molecule has the biological activity of binding to albumin in blood and that of binding to FAP protein. The present invention is combined with radioactive nuclide Lu-177, Ac-225, Ga-67 or In-111 for long-circulation FAP targeting in the body. Higher accumulation in expressing FAP tumors is achieved, and the accumulation time of inhibitors in tumors is prolonged. The present invention allows radioactivity to act in the tumor for a long time, thereby reducing the radioactivity concentration or reducing the frequency of radioactive inhibitor administration to inhibit tumor growth.

  • Publication number: 20250072944
    Abstract: A bone fixation assembly includes a bone plate, a first bone screw and a second bone screw. The first and second bone screws penetrate through two holes respectively. The first bone screw has a left-handed thread while the second bone screw has a right-handed thread. With different thread directions of the bone screws, the bone screws are hard to be loosened so that broken bones are fixed firmly. Accordingly, size of the bone plate is able to be reduced for miniaturization.

  • Patent number: 10991422
    Abstract: High-efficiency control technology for non-volatile memory. A non-volatile memory has single level cells (SLCs) and multiple level cells (e.g., MLCs or TLCs) and is controlled by a controller. According to the controller at the device end, a host allocates a system memory to provide a host memory buffer (HMB). The controller at the device end uses the HMB to buffer write data issued by the host, and then flushes the write data from the HMB to multi-level cells of the non-volatile memory without passing single level cells of the non-volatile memory to reduce write amplification problems due to the frequent use of the single-level cells.

  • Patent number: 10719272
    Abstract: Multi-channel accessing of non-volatile memory. A controller uses three kinds of tables to manage cross-channel accessing areas and, accordingly, to access the non-volatile memory through multiple channels. Each cross-channel accessing area includes M storage units, where M is an integer greater than 1. For each cross-channel accessing area, the first table marks whether there is a need for storage unit substitution and points to substitution information. The substitution information is stored in the second table and the third table. For each cross-channel accessing area marked in the first table, the second table stores M bits corresponding to M storage units of the marked cross-channel accessing area for substitution indication, and related substitute storage unit indication is stored in the third table.
