Metabolic relationships among the plasma lipoproteins

Plasma lipoproteins in fish.

Isolation of plasma lipoproteins

Lipoproteins were isolated from plasma of man, dog, rabbit, rat, and chicken by ultracentrifugation in continuous density gradients using the B14 titanium and B15 titanium zonal rotors. Both the VLDL and the LDL of human plasma were separated easily from the HDL and from the other more plentiful plasma proteins by centrifugation for only 1 or 2 hr in the B14 or B15 rotor, respectively. Satisfac...

Relationships between the proton nuclear magnetic resonance properties of plasma lipoproteins and cancer.

We conducted a comprehensive investigation of the origin of nuclear magnetic resonance (NMR) lineshape variability of plasma lipids among healthy individuals and those with cancer. The methyl and methylene resonances of lipid in human plasma, whose linewidths have been reported to correlate with the presence of malignancy, are composed of the overlapping resonances of "mobile" protons from the ...

Evaluation of plasma lipids and lipoproteins in patients with psoriasis

Psoriasis is an epidermal disease characterized by chronic relapsing papillon squamous erythematous plaques which may develop in the skin of elbows, knees and extensor surfaces. The cause of psoriasis is unknown. The primary etiologic factor may be related to excessive uncontrolled synthesis is resulting from changes in (1) the function of growth factors ( EGF),(2) presence of proto- oncogenes,...

Plasma lipoproteins in normal and preeclamptic pregnant women

Background: Preeclampsia is one of the most common complications of pregnancy. It is the cause of high morbidity and mortality for mothers and fetuses, especially in developing countries. The etiology of preeclampsia is unknown. One of the hypothesis on pathophysiology of preeclampsia is dyslipidemia. The aim of this study was to determine maternal plasma levels of lipoproteins in patients with...
