Abstract: Provided is a use of a compound represented by Formula (I) or a nitrogen oxide, solvate, metabolite, pharmaceutically acceptable salt, or prodrug thereof in the preparation of medicament.

Abstract: A camera includes an always on circuit including a motion or other sensor and/or communications module that are always provided with electrical power, and a sleep circuit including an imaging module configured to activate and provide power to components of the sleep circuit only intermittently and based on a signal from the always on circuit. The communications module can send a notification that the motion sensor has detected motion before or during a start up time period when the imaging module is not ready to capture image data. The communications module can receive a signal while components of the sleep circuit are in a low power mode indicating that a user has activated an application via which the user can request image data from the imaging module, and in response the imaging module can be activated to be in an operational state.

Abstract: A soft tissue simulator for magnetic resonance imaging and a method for simulated testing are disclosed. The simulator includes a base for supporting a soft tissue or organ sample, an indenter, a pneumatic cylinder and an air source. The pneumatic cylinder is separated into a first chamber and a second chamber. The air source includes a pneumatic generation source and a reversing valve having a first air outlet and a second air outlet which are respectively connected to the first and second chambers. The reversing valve is used to control compressed air to enter the first or second chamber to control the movement of the indenter. The indenter is controlled to have a periodic or unidirectional movement, to simulate the movement of a human organ or soft tissue. The simulator can used for the measurement of physical characteristics of soft tissue based on magnetic resonance imaging.
