It is unusual to find systemic failure in the absence of liver metastases,[1] although the portosystemic shunting that exists at the anorectal junction does permit hematogenous spread outside the portal circulation to the internal iliac vessels and the cava.
A flexible-fuel vehicle (FFV) or dual-fuel vehicle (colloquially called a flex-fuel vehicle) is an alternative fuel vehicle with an internal combustion engine designed to run on more than one fuel, usually gasoline blended with either ethanol or methanol fuel, and both fuels are stored in the same common tank.
GM identifies its E85 ethanol flex-fuel vehicles with Flex Fuel E85 badges and yellow fuel-filler caps. Ford labels its E85 ethanol flex-fuel models with a tree-and-road logo and a decal reading FFV, for Flexible Fuel Vehicle. The Chryslers, Dodges, and Jeeps display a silver Flex Fuel E85 tag. E85 ethanol flex-fuel vehicles from Mercedes-Benz and Nissan do not carry any special identification.
