Hemolytic-uremic syndrome. Hemolytic-uremic syndrome (or haemolytic-uraemic syndrome), abbreviated HUS, is a disease characterized by a triad of hemolytic anemia (anemia caused by destruction of red blood cells), acute kidney failure (uremia), and a low platelet count (thrombocytopenia). It predominantly, but not exclusively, affects children.
Marco Polo (1254-1324) was a Venetian merchant believed to have journeyed across Asia at the height of the Mongol Empire. He first set out at age 17 with his father and uncle, traveling overland along what later became known as the Silk Road.
He was released in 1299, became a wealthy merchant, married, and had three children. He died in 1324 and was buried in the church of San Lorenzo in Venice. Marco Polo was not the first European to reach China (see Europeans in Medieval China), but he was the first to leave a detailed chronicle of his experience. This book inspired Christopher Columbus and many other travellers.
