Intercorrelations among plasma high density lipoprotein, obesity and triglycerides in a normal population
The interrelationships among fatness measures, plasma triglycerides and high density lipoproteins (HDL) were examined in 131 normal adult subjects: 38 men aged 27–46, 40 men aged 47–66, 29 women aged 27–46 and...

Effects of estrogens and progestins on high density lipoproteins
High density lipoprotein (HDL) levels are known to be higher in women than in men, and to increase with estrogen use. To assess the effects of estrogens on HDL subspecies, analytic ultracentrifuge measurements...

A comparison of simplified methods for lipoprotein quantification using the analytic ultracentrifuge as a standard
Two simplified methods for quantitative lipoprotein analysis have been calibrated and compared with each other using analytic ultracentrifugation as a standard reference procedure. The first method was the Fri...

Lipid and lipoprotein measurements in a normal adult American population
From a parent population of 774, a subpopulation of 160 normal adults ages 27–66 was randomly selected, 20 from each decade and sex. A detailed comparison was made by analytic ultracentrifugation and complete ...

Subfractionation of Sf 4–105, Sf 4–20 and high density lipoproteins
Subfractionation of the total low density Sf 4–105, the low density Sf 4–20 and high density plasma (or serum) lipoproteins has been accomplished using a cumulative flotation rate procedure. Fractionation employs...

Flotation rates, molecular weights and hydrated densities of the low-density lipoproteins
A method involving three computer programs is described for characterizing the major component of the Sf 0–12 low-density lipoprotein class by its Sf rate, hydrated density and molecular weight. All necessary inf...

Ultracentrifugal isolation of serum chylomicron-containing fractions with quantitation by infrared spectrometry and NCH elemental analysis
An ultracentrifugal method for isolating chylomicron-containing fractions from serum by flotation, using either standard Spinco swinging-bucket rotors or a specially fabricated swinging-bucket rotor, is descri...
