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.
Before discussing about this topic of enlarged aorta, letâs tackle first the aortaâs main function in our body. Aorta is the largest artery in the heart. The function of the aorta carries oxygenated blood from the heart passing through the left ventricle, passing the chest, to the belly or abdomen and the pelvis. Atherosclerosis â it is known as the hardening of the arteries of the heart. 2  This is the most common cause of enlarged aorta for it will damage mainly the arteries. 3  Injury â sudden force applied which can damage the arteries in specified body parts like the chest and abdomen such as a vehicle accident.
