Key result
VLDL B-apoprotein pool size was positively correlated with flux and negatively correlated with fractional removal rate, indicating expansion is driven by increased input and decreased removal.
Why the study?
What are the relationships between pool size, flux, and removal rate of VLDL B-apoprotein in normolipidemic and hyperlipoproteinemic human subjects?
Observational (n=28)
What are the relationships between pool size, flux, and removal rate of VLDL B-apoprotein in normolipidemic and hyperlipoproteinemic human subjects?
Expansion of VLDL pool size in hyperlipoproteinemia is driven by both increased input and decreased removal, with overweight contributing to expanded pools by decreasing removal.

Supports dual kinetic defects in VLDL expansion; leaves open whether targeting input or removal alters outcomes.
Nestel et al. (1979) conducted an observational in Hyperlipoproteinemia (n=28). Hyperlipoproteinemia and body weight vs. Normolipidemic subjects was evaluated on VLDL B-apoprotein pool size (MA), flux (PRA), and fractional removal rate (KAA). VLDL B-apoprotein pool size was positively correlated with flux and negatively correlated with fractional removal rate, indicating expansion is driven by increased input and decreased removal.
