Abstract: In a non-limiting embodiment, there is provided a pharmaceutical composition for prevention and/or treatment of uremic pruritus comprising an IL-31 antagonist as an active ingredient.

Abstract: An air-fuel mixing and delivery apparatus for an internal combustion engine is situated to be shielded from exposure to water or mud during travel of a vehicle, to protect fuel system components such as a fuel injector. In the air-fuel mixing and delivery apparatus, an air-intake port, a throttle body, and an air cleaner are arranged substantially linearly and extending rearwardly above a main body of the internal combustion engine, toward the rear of the vehicle. A fuel injector is positioned on the side of the throttle body, below a seat of the vehicle. The apparatus may include a fuel pump operatively attached to the throttle body as well as a fuel injector, so that the apparatus can be compactly consolidated. Optionally, a pressure regulator may also be attached to the throttle body.

Abstract: A motorcycle, such as a scooter-type motorcycle, includes an engine main body. The engine main body is non-swingably supported by a frame at a location under a seat. A transmission case is swingably supported by the engine main body. A rear wheel is attached to the transmission case and hence swingable relative to the frame. A fuel system is provided atop the engine main body, and hence is not swingably relative to the frame. The engine main body has cylinder bores which are spaced across the width of the motorcycle. The cylinder bores are tilted upwardly and forwardly, so as to create a space below a forward portion of the engine main body. A fuel tank has a rear portion disposed below the forward portion of the engine main body.
