A portable suction device for removing liquid from an engine includes a plastic tank including a pump aperture for enabling removal of air or gases from the tank and a receiving aperture for receiving a liquid or gas from an engine. Examples of the elongated element include a shaft, such as a guidewire. An actuator arm is coupled to each trunnions, outside the casing. The present invention also is drawn to methods of determining whether a test agent is a carcinogen by measuring protein synthesis or post-translational modifications from mammalian cells treated with the test agent compared with mammalian cells treated with a known carcinogen.
