A computer bezel includes a bezel body, a light-guide structure mounted to the bezel body, and two light sources mounted on the bezel body. In the case of recording, the moving image recordingplayback device sequentially outputs a plurality of image frames that constitute the moving image at a predetermined frame rate and, of the plurality of image frames, wholly records image frames at intervals of a predetermined number of frames and partly records each of the other image frames, onto at least one recording medium. It also comprises a switching valve mechanism for switching the air supplied to the pump. The projection is disposable in a first position with the distal portion of the axial cavity and the distal end of the first extension is disposed in a non-expanded orientation. A rotating tool extension is at least partially inserted within the liner. In a related aspect, the invention provides a method for treating or preventing HCV infection in a patient, comprising administering to the patient an effective amount of an agent, composition, or construct of the invention as described herein.
