  • Publication number: 20240228586
    Abstract: The disclosure relates to the engineering of collagen-binding modification of masked therapeutic agents comprising one or more tumor-associated protease cleavage sites. Upon exposure to tumor-associated proteases in the tumor microenvironment, the polypeptide is cleaved, which unmasks the therapeutic agent, reducing off-target side effects and toxicity associated with systemic administration. Accordingly, aspects of the disclosure relate to a polypeptide comprising a therapeutic agent linked to a masking agent through a linker, wherein the linker comprises one or more tumor-associated protease cleavage sites, and wherein the masking agent blocks the association of the therapeutic agent to its therapeutic target, and further wherein the polypeptide is operatively linked to a collagen binding domain or a tumor-targeting agent.

  • Patent number: 11425644
    Abstract: Apparatuses, methods, and systems are disclosed herein to provide an information processing apparatus and a control method which do not cause a reduction in the output of radio waves when a human body is not approaching. A communication unit communicates with other devices wirelessly, a detection unit detects a physical quantity varying with the approach of an object, and a control unit causes the communication unit to reduce the output of radio waves when the amount of change in physical quantity exceeds a predetermined threshold value. When a predetermined member is in a position to approach a first chassis on which the communication unit and the detection unit are mounted, the control unit compensates for a change in physical quantity detected by the detection unit due to the approach of the member.

  • Patent number: 10228281
    Abstract: In an optical sensor, a detecting part includes detecting elements, and a light-shielding portion providing directional characteristics of light to the detecting elements such that the detecting elements indicate different intensities of light received in a specified direction. A signal processing part has an adjustment value for processing detection signals. The adjustment value is set as follows. Based on information of an inclination angle of a window glass of a vehicle to which the detecting part is attached, from the detecting elements, a detecting element having a directional characteristic of light suitable for the inclination angle is selected. The adjustment value is then set so as to coincide a signal value of a detection signal of the selected detecting element with a target value, when the detecting part is irradiated with light in a predetermined direction in a state where the detecting part is inclined at the inclination angle.

  • Patent number: 8696133
    Abstract: A projection optical system (6) comprises a relay optical system (61), a PBS prism (71), and two projection lenses (81). The image light beam from a DMD (5) enters the PBS prism (71) via the relay optical system (61), is polarization-split there, and is directed to a screen by means of the two projection lenses (81). Displaying an image by means of the DMD (5) is controlled while the polarized states of the light beams produced by the polarization split by means of the PBS prism (71) are controlled. Thereby, a three-dimensionally viewable image and a high-resolution image created by pixel-offset can be projected. Since the relay optical system (61) is provided, the lens backs of the projection lenses (81) can be shortened, and the projection lenses (81) and further the projection optical system (6) can be made compact.
