  • Publication number: 20210040478
    Abstract: The present invention provides methods for retaining and expressing physiologically active substances in a target tissue-specific-manner, by administering the physiologically active substances to target submucous tissue. Specifically, the present inventors demonstrated that, when physiologically active substances were directly administered into submucous tissues without using a carrier, the physiologically active substances were effectively and safely retained at the administration sites over long periods without loss and diffusion, and produced the effect acting in a reservoir-like fashion. The physiologically active substances administered as described above were demonstrated to produce the therapeutic effect without having an influence on organs other than the administered organ.

  • Patent number: 10871115
    Abstract: When atmospheric pressure (Pa) which varies according to altitude is higher than a predetermined pressure threshold (Path) during idle operation in which catalyst warm-up request is issued, an intake pressure is controlled, through a throttle valve (19), to an intake pressure at which an intake air amount required to promote the warm-up of a catalyst converter (26) is obtained. When the atmospheric pressure (Pa) is lower than the predetermined pressure threshold (Path), the intake pressure is controlled, through a throttle valve (19), to an intake pressure (Pa?Pb) at which a differential pressure (Pb) required by a brake booster (8) is obtained. Accordingly, negative pressure in the brake booster (8) can be secured while promoting the warm-up of the catalyst during the idle operation.
