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.
The Etruscans, being heavily influenced by the Greeks, also introduced the Greek alphabet, thus introducing Greek influence into Roman culture. In fact, Roman nobles during this period would send their sons to be educated in Etruscan schools much as they would later send their sons to Greece for an education.
