Warfarin (Coumadin) is sometimes prescribed as a blood thinner because it is an effective vitamin K antagonist (blocks the formation of vitamin K). The activated partial thromboplastin time (PTT) measures the function of several other clotting factors, found in the intrinsic and common blood clotting pathways.
Etruscans and the early Roman monarchy made several contributions to the Roman republic. The establishment of Rome was through Romulus and Remus. Through legends, they were thought to be abandoned by their uncle, and raised up by a she wolf.
By 500 B.C.E., the Etruscans had also made Rome most important city in the central Italian region of Latium. This enabled it to dominate its close neighbors, the Latins and finally encouraged it to rebel against its masters. Two other factors aided the Romans in their struggle.
