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.
The aorta should be imaged in B mode from the diaphragm. A Grey scale image of the aorta at the largest diameter, noting intraluminal echoes, should be obtained. The maximal AP and Transverse Diameter are measured in the Proximal, Mid and Distal abdominal aorta. The maximal AP and Transverse diameters should be measured in the origin of the iliac arteries and if an aneurysm is seen then the scan should be extended to include the common , internal and external iliac arteries .
