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.
During the Roman Republic, several dates were given for the founding of the city between 753 BC and 728 BC. Finally, under the Roman Empire, the date suggested by Marcus Terentius Varro, 753 BC, was agreed upon, but in the Fasti Capitolini the year given was 752.
