  • Publication number: 20240383998
    Abstract: The present disclosure relates to an anti-CD20 asymmetric antibody including a single-chain variable fragment (scFv) on one side and an antigen-binding fragment (Fab) on the other side. Compared to an antibody having a symmetric structure, the asymmetric antibody of the present disclosure effectively activates complements and exhibits significantly improved complement-dependent cytotoxicity (CDC), and thus can be advantageously used as an effective therapeutic agent or therapeutic adjuvant for treating cancer.

  • Publication number: 20240141061
    Abstract: The present disclosure relates to an antibody binding specifically to CD55 or an antigen-binding fragment thereof; and a composition for preventing, treating and/or diagnosing cancer containing the same. The antibody of the present disclosure may be used as an effective therapeutic composition for various CD55-mediated diseases since it shows high binding ability and inhibitory effect for the CD55 protein which promotes tumor growth by inhibiting the complement immune mechanism. In addition, the antibody of the present disclosure may be usefully used as an effective therapeutic adjuvant that fundamentally removes drug resistance and remarkably improves therapeutic responsiveness in various diseases in which resistance to therapeutic agents with CDC (complement-dependent cytotoxicity) as a mechanism of action has been induced due to overexpression of CD55.

  • Patent number: 10247739
    Abstract: The present invention relates to a method for the immunological measurement using a hapten and an antibody binding to the hapten as a reference antibody, and a device for the immunological measurement using the reference antibody. According to the present invention, the method and the device for the immunological measurement can be used in an immunoassay by reflecting surrounding environments, for example, by reflecting a numerical value in a test zone, which is changed by external factors such as temperatures of a sample and a device, an amount and components of an injected sample, variations of the device, and the like, in a reference zone and changing the numerical value in the test zone, and can be useful in minimizing analysis errors due to a low probability of causing a non-specific reaction with a material in the sample.

  • Patent number: 10047648
    Abstract: An oil cooler for a vehicle includes an inflow tank through which a working fluid flows in. An outflow tank is spaced apart from the inflow tank by a predetermined interval and has a discharge hole at one side which faces the inflow tank. A plurality of tubes connect the inflow tank with the outflow tank longitudinally such that the working fluid flows therethrough. A bypass valve is integrally mounted at an outer side of the one end portion of the inflow tank and connected to an inner side of the inflow tank to bypass or flow the working fluid flowed therein into the inflow tank by selectively opening and closing according to a temperature of the working fluid. An outflow pipe has one end mounted to the discharge hole and another end thereof mounted to the bypass valve to connect the outflow tank with the bypass valve.

  • Patent number: 9859617
    Abstract: An antenna methodology where a set of antennas are formed that take the shape of a mobile wireless device and can be integrated into the outer housing of the mobile device. Tuning points are integrated into the design to provide the capability to compensate for hand effects and loading while the mobile device and antenna are touched by the user. The body then becomes a part of the antenna and acts as an anchor for the poles within the matching circuit. These antennas are actively tuned based on detection criteria while dynamically tracking system performance. The structure is based on a loaded loop coupled to an isolated magnetic dipole (IMD) element. The loop is actively tuned according to design rules residing in a processor in the mobile device.

  • Patent number: 9755305
    Abstract: An active antenna and associated circuit topology is adapted to provide active impedance matching and band switching of the antenna using a shared tunable component. Using a shared tunable component, such as a tunable capacitor or other tunable component, the antenna provides a low cost and effective active antenna solution. In certain embodiments, one or more passive components can be further utilized to design band switching of the antenna from a first frequency to a second desired frequency.

  • Patent number: 9692122
    Abstract: An active antenna system and algorithm is described that provides for dynamic tuning and optimization of antenna system parameters for a MIMO system where correlation and isolation between antennas in the system are dynamically altered to provide for greater throughput. As one or multiple antennas are loaded or de-tuned due to environmental changes, corrections to correlation and/or isolation are made by selecting the optimal antenna radiation pattern and by adjusting electrical length and/or reactive loading of transmission lines connecting the antennas. Multiple Isolated Magnetic Dipole (IMD) antennas are co-located and connected with a feed network that can include switches that adjust phase length for transmission lines connecting the antennas. Filtering is integrated into the feed network to improve rejection of unwanted frequencies. Filtering can also be implemented on the antenna structure.
