  • Publication number: 20230270790
    Abstract: Amyotrophic lateral sclerosis (ALS) is a life-threatening neurodegenerative disease characterized by the progressive loss of motor neurons. Muse cells are endogenous reparative pluripotent-like stem cells distributed to various tissues. Once intravenously injected, such cells, upon sensing sphingosine-1-phosphate produced by damaged cells, settle selectively on damaged sites, and after homing, can exhibit multiphase effects including natural differentiation into tissue-protecting and tissue-reconstructing cells. In the present invention, with G93A-Tg mice serving as an ALS model, human Muse cells injected intravenously successfully homed into the lumbar cord, mainly at the pia mater and the lower white matter, and expressed glial-like forms and GFAP. Meanwhile, no such homing or differentiation was observed in the case of human mesenchymal stem cells (MSCs), and, rather, MSCs were found distributed to the lungs.

  • Patent number: 11722052
    Abstract: A control method, a controller, and a control system including a converter and the controller are provided to improve load responsiveness of control by the converter. The converter has a primary circuit that includes a voltage generation circuit for generating a square wave and a resonant circuit for converting a waveform of the generated square wave, and a secondary circuit that is electromagnetically coupled to the primary circuit and that generates an induced electromotive force. The controller controls the voltage generation circuit by a control target power factor. To implement power factor-based control, the controller controls the voltage generation circuit, based on a derived power factor derived from an active power and an apparent power relevant to the resonant circuit in the primary circuit or a derived power factor derived from a phase of the primary circuit.

  • Publication number: 20230144545
    Abstract: The present invention provides an inflammatory pulmonary disease agent capable of effectively preventing and/or treating an inflammatory pulmonary disease, and specifically relates to a prophylactic and/or therapeutic agent for an inflammatory pulmonary disease containing, as an active ingredient, an antibody or an antibody fragment having antigen-binding activity for an S100A8/A9 heterodimer. The inflammatory pulmonary disease can be effectively prevented and/or treated by blocking interaction between S100A8/A9 and a group of receptors therefor. Specifically, the inflammatory pulmonary disease can be effectively prevented and/or treated by: blocking interaction between S100A8/A9 and RAGE, which is a receptor therefor, to suppress: the expression of NF-?B, which is a transcription factor present downstream of RAGE and induces the expression of various inflammatory cytokines; the proliferation of activated fibroblasts; and the differentiation of activated fibroblasts into myofibroblasts.
