  • Publication number: 20240132621
    Abstract: Disclosed herein an isolated neutralizing antibody, which is capable of specifically binding to chitinase-3-like protein-1 (YKL-40) and uses thereof. The neutralizing antibody can further conjugate with a metal chelator to form an antibody complex. Further, labeling the antibody complex with a radioactive metal nuclide results in formation of a radioactive antibody complex, which can be used as a contrast agent and treatment for YKL-40 over-expression-related diseases. The radioactive antibody complex can specifically bind to YKL-40, and can be used for diagnosis and the preparation of the use of the treatment for cancers related to YKL-40 over-expression.

  • Patent number: 7432866
    Abstract: Disclosed is an antenna device having a substrate, an antenna element for transceiving a wireless signal, an antenna signal feeding line for feeding the wireless signal, and an ion-implanted resonant pattern, which includes a first coupling pattern implanted in the substrate by an Ion-implantation process and a second coupling pattern formed at a position corresponding to the first coupling pattern with a predetermined distance therebetween, formed at an adjacent position with respect to the antenna element. As the antenna element transceives the wireless signal of the predetermined radiation frequency and generates an induction voltage, the first coupling pattern and the second coupling pattern each generates a coupled induction voltage and a capacitance therebetween, hence forming a resonance with the antenna element.
