Though the U.S. Congress outlawed the African slave trade in 1808, the domestic trade flourished, and the slave population in the U.S. nearly tripled over the next 50 years. By 1860 it had reached nearly 4 million, with more than half living in the cotton-producing states of the South.
a focus of T2 hyperINTENSITY means that the signal from that area has different tissue characteristics compared to normal brian tissue. Usually this is due to an increased water content of the tissue.Pathological tissue usually has more water than normal brain so this is a good type to scan to pick this up.however it does not reveal any information about what it is although the site and pattern of abnormality does.sually this is due to an increased water content of the tissue.

The measurement of total iron binding in the same specimen may facilitate the clinician's ability to distinguish between low serum iron levels caused by iron deficiency from those related to inflammatory neoplastic disorders. The assay for iron measures the amount of iron which is bound to transferrin. The total iron binding capacity (TIBC) measures the amount of iron that would appear in blood if all the transferrin were saturated with iron. It is an indirect measurement of transferrin concentrations but expressed as an iron measurement. To obtain the percent saturation, the serum iron is divided by the TIBC which gives the actual amount of saturated transferrin. The percent saturation is low in iron deficiency and high in iron storage diseases.
