  • Publication number: 20240132021
    Abstract: An apparatus for controlling a discharge pressure of a fluid includes: a pump configured to suck the fluid through an inlet or to discharge the sucked fluid through an outlet; a distributor connected to the pump and to an injection nozzle provided by a sensor and configured to distribute the fluid discharged from the pump to the sensor; and a controller. The controller is configured to control the pump to operate selectively in accordance with detection of contamination of the sensor and to control operation of the distributor to be forcibly delayed during operation of the pump such that the fluid distributed to the sensor, when detected as being contaminated, is controlled to reach a selected required discharge pressure of different required discharge pressures selected in accordance with water amount information and a degree of contamination of the sensor.

  • Patent number: 11571460
    Abstract: The present invention relates to a composition including melittin as an active ingredient for removing an M2-type tumor-associated macrophage (TAM), and more specifically, the present invention relates to a composition exhibiting an effect of selectively suppressing only M2-type tumor-associated macrophages among tumor-associated macrophages. The composition according to the present invention only suppresses M2-type tumor-associated macrophages without affecting M1-type tumor-associated macrophages or cancer cells, thus exhibiting anti-cancer and metastasis suppressing effects by blocking angiogenesis through control of the microenvironment of cancer cells, while reducing the side-effects of existing anti-cancer effects.

  • Patent number: 11484601
    Abstract: The present invention relates to a melittin-anticancer drug conjugate in which melittin and an anticancer drug are conjugated, and to a method of preparing a melittin-anticancer drug conjugate by connecting melittin and an anticancer drug. A conjugate of the present invention is an anticancer material for targeting M2-type tumor-associated macrophages (TAM) and exhibits an excellent effect of selectively selecting M2-type tumor-associated macrophages (TAM), and thus may be used for a use of drug delivery for targeting M2-type tumor-associated macrophages.

  • Publication number: 20220204939
    Abstract: The present invention relates to: a method for preparing a stem cell culture solution which contains growth factors and cytokines and is obtained by culturing, in a serum-free medium, mesenchymal stem cells cultured in a medium containing human platelet lysates (hPLs); and a cosmetic composition using the stem cell culture solution. When the method for preparing a mesenchymal stem cell culture solution obtained from mesenchymal stem cells cultured in an hPL-containing medium is used, it is possible to obtain a mesenchymal stem cell culture solution which has a higher amount of cytokines and growth factors than that of a mesenchymal stem cell culture solution obtained from mesenchymal stem cells cultured in an FBS-containing medium, and has excellent efficacy in the promotion of human dermal fibroblast proliferation, collagen synthesis, elastin synthesis, inhibition of melanin synthesis, and hair growth.
