  • Patent number: 8716230
    Abstract: The inventors examined the role of MK in experimental autoimmune encephalomyelitis, which is a human model for multiple sclerosis. As a result, they discovered that MK has the effect of inhibiting regulatory T cells, and that the autoimmune mechanism induced by type 1 helper T cells can be suppressed by inhibiting MK expression or its activity, thereby increasing the number of regulatory T cells. Furthermore, it was found that diseases associated with the functional disorder of regulatory T cells can be treated with the administration of an inhibitor that inhibits MK expression or activity.

  • Publication number: 20140013232
    Abstract: Provided is a presentation system in which data communication is performed between presenter-side viewing terminal with which a presenter views a slide image prepared in advance to make a presentation; and an audience-side viewing terminal with which an audience views the slide image, whereby the slide image designated at the presenter-side viewing terminal is displayed on the audience-side viewing terminal. The presentation system includes an audience-side portable terminal that receives an input operation by the audience. Upon receipt of the input operation by the audience, the audience-side portable terminal stores memo information indicating a content of the input operation; obtains a slide ID used to identify the slide image being displayed on the audience-side viewing terminal; and records the memo information in association with the slide ID.

  • Publication number: 20110313819
    Abstract: Provided is a business management system that performs a business management of a plurality of stores in a collective manner. The system includes a first terminal device, a second terminal device, and a management server. The first terminal device sets a time at which a first operation is inputted by a visitor via an input device installed in the store as a visiting time, and generates a visitor number for sequentially leading the visitor while associating the visitor number with the visiting time. The second terminal device inputs the visitor number and a preset second operation. The management server obtains a service time (a time period from a service start time till a service end time) and a waiting time (a time period from the visiting time till the service start time), and aggregates the service time and the waiting time on a time-series basis for each store.
