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.
In 509 BCE with the exit of the last Etruscan king, Tarquin the Elder, the Roman people were presented with a unique opportunity, an opportunity that would eventually have an immense impact on the rest of Europe for centuries to come: the chance to create a new government, a republic.
