True Protein-General Information. True protein, as the name implies, is the actual amount of protein in milk, while the former standard, crude protein, is derived from the nitrogen content in milk.Crude protein over evaluates the amount of protein in milk because it includes non-protein nitrogen.The new Federal Milk Marketing Orders, which went into effect January 1, 2000, pay for protein on a true-protein scale instead of the crude-protein scale that had been used previously in many parts of the country.rude protein over evaluates the amount of protein in milk because it includes non-protein nitrogen.

In adults, a diameter of 2.1 cm/m2 has been considered the upper normal range in ascending aorta. Transthoracic echocardiography suffices to quantify maximum aortic root and proximal ascending aorta diameters when the acoustic window is adequate.
Normal Aorta. An aneurysm is a swelling of the aorta, the main blood vessel of the body. The aorta begins just above the heart and rises straight up in the front of the chest (ascending aorta) toward the top of the body. At that level, it takes a turn, called the aortic arch, toward the back of the body.
