Combination of Delipidized High Density Lipoprotein with Lipids

Combination of delipidized high density lipoprotein with lipids.

A method has been developed for combining lipids in vitro with delipidized high density lipoprotein (apo-HDL) by mixing a concentrated petroleum ether solution of lipids with an aqueous solution of apo-HDL. When a mixture of plasma lipids was used, combination of phospholipids and cholesterol was observed in amounts comparable with those present in native HDL; triglycerides and cholesterol este...

Influence of menopause on high density lipoprotein-cholesterol and lipids.

It has been generally accepted that high density lipoprotein cholesterol (HDL-C) level decreases with menopause in women. However, recent reports show different results. There is very little data concerning perimenopausal women. To verify these findings, lipids and lipoprotein(a) [Lp(a)] levels were compared among pre-, peri- and postmenopausal women of similar mean ages. Postmenopausal women h...

Biosynthesis of high density lipoprotein by chicken liver: conjugation of nascent lipids with apoprotein A1

To study the assembly of newly synthesized lipids with apoprotein A1, we administered [2-3H]glycerol to young chickens and determined the hepatic intracellular sites of lipid synthesis and association of nascent lipids with apoprotein A1. [2-3H]glycerol was rapidly incorporated into hepatic lipids, reaching maximal levels at 5 min, and this preceded the appearance of lipid radioactivity in the ...

High density Lipoprotein; What to Measure: Quality or Quantity?

Effect of moderate exercise on serum lipids in young men with low high density lipoprotein cholesterol.

Fifty-five healthy, sedentary, nonsmoking, and nonobese 24- to 26-year-old men who had low plasma concentrations of high density lipoprotein (HDL) cholesterol were selected for a study of the effect of short-term exercise on plasma lipid and lipoprotein concentrations. The participants were randomized into two groups. Of these, 28 were assigned to a 9-week program of submaximal aerobic exercise...
