The diabetic dyslipidemia is one of the most important risk factor in the development of coronary artery disease. The low density lipoprotein (LDL)-like nanoemulsions is being used to study the clearance of cholesteryl ester and free cholesterol from intravascular in patients with advanced coronary artery disease and it was shown a higher removal of free cholesterol and higher deposit in vases of this patients. The aim of this study is to analyze the plasma kinetics of both forms of cholesterol(free ad esterified) in type 2 diabetes patients without a previous history of cardiovascular disease.
Hypercholesterolemia is not typical of type 2 diabetes mellitus dyslipidemia, but alterations in LDL may occur related to atherogenesis.Cholesterol exist in two main forms in organism: free cholesterol and the esterified cholesterol. An artificial model to study this two forms of cholesterol is the use of LDL-like nanoemulsion doubly labeled with 14C-cholesteryl esters and 3H- cholesterol. This nanoemulsion is made without protein and when in the intravascular compartment it is able to acquires apolipoproteins from others lipoproteins, such apos A's, C's and E. This model allowed us to use the nanoemulsion particle as a probe to study the lipoproteins receptor binding and the cholesterol esterification process.

A subclass of DIABETES MELLITUS that is not INSULIN-responsive or dependent (NIDDM). It is characterized initially by INSULIN RESISTANCE and HYPERINSULINEMIA; and eventually by GLUCOSE INTOLERANCE; HYPERGLYCEMIA; and overt diabetes. Type II diabetes mellitus is no longer considered a disease exclusively found in adults. Patients seldom develop KETOSIS but often exhibit OBESITY.
The time period before the development of symptomatic diabetes. For example, certain risk factors can be observed in subjects who subsequently develop INSULIN RESISTANCE as in type 2 diabetes (DIABETES MELLITUS, TYPE 2).
A severe type of hyperlipidemia, sometimes familial, that it is characterized by the elevation of both plasma CHYLOMICRONS and TRIGLYCERIDES contained in VERY-LOW-DENSITY LIPOPROTEINS. Type V hyperlipoproteinemia is often associated with DIABETES MELLITUS and is not caused by reduced LIPOPROTEIN LIPASE activity as in HYPERLIPOPROTEINEMIA TYPE I .
A subtype of DIABETES MELLITUS that is characterized by INSULIN deficiency. It is manifested by the sudden onset of severe HYPERGLYCEMIA, rapid progression to DIABETIC KETOACIDOSIS, and DEATH unless treated with insulin. The disease may occur at any age, but is most common in childhood or adolescence.
A type of diabetes mellitus that is characterized by severe INSULIN RESISTANCE and LIPODYSTROPHY. The latter may be generalized, partial, acquired, or congenital (LIPODYSTROPHY, CONGENITAL GENERALIZED).
