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.
If you arenât sure, youâre not alone. Though there are millions of flex-fuel vehicles (FFVs) on the road, many owners arenât aware they have one. FFVs look just like regular vehicles, with one major difference: they can run on either gas or E85 (a blend of 85 percent ethanol and 15 percent gasoline).
