The composition of the plasma lipoproteins is continuously modified during their intravascular metabolism, as a result of a dynamic exchange and net transfer of lipids between particles or between particles and cells. Specialized proteins, the plasma lipid transfer proteins, facilitate the transfer and exchange of phospholipids, cholesteryl esters, and triglycerides between the lipoproteins. Al...

The plasma lipid transfer proteins mediate the transfer and exchange of phospholipids and neutral lipids between the plasma lipoproteins. The cholesteryl ester transfer protein (CETP) and the phospholipid transfer protein (PLTP) are members of the lipid transfer/lipopolysaccharide binding gene family. The CETP contains binding sites for cholesteryl ester and triglycerides and probably acts by a...

© 2008 Elsevier. All rights reserved. The pentavalent Tc-99m dimercaptosuccinic acid (Tc99m (V) DMSA, Tc(V)-DMSA) radiotracer has become more widely used. The accumulation of Tc(V)-DMSA in tumors was first reported in 1981 [1], and this tracer has subsequently been shown to localize in a variety of tumors [2,3]. Tc(V)-DMSA has also been used to depict abscesses and other inflammatory lesions [4...

Evidence has been accumulating for the selective localization of radioactive plasma proteins in tumors. A number of clinical studies have shown that plasma proteins labeled with Il31 can be utilized for localization of hepatic metastases as well as primary cerebral neoplasms."'0"' Studies on localization of radioactive plasma proteins in animal tumors have been carried out by Babson and Winnick...
