Stability of serum high-density lipoprotein-microRNAs for preanalytical conditions

MicroRNAs and High-Density Lipoprotein Cholesterol Metabolism.

MicroRNAs (miRNAs) are small non-protein-coding RNAs that negatively regulate gene expression. They bind to the 3'-untranslated region of specific mRNAs and inhibit translation or promote mRNA degradation. Dyslipidemia/hyperlipidemia is a well-accepted risk factor for the development of atherosclerosis. The pathogenesis factors involved in lipid abnormalities are being examined extensively, and...

Serum High Density Lipoprotein Cholesterol

High -density lipoprotein cholesterol as a predictor for diabetes mellitus

Background: Diabetes is a prevalent chronic disease around the world. To evaluate risk of diabetes comprehensively, we developed a score model for the risk prediction with HDL-C as a protective factor. Methods: We extracted physical examination data of 2728 individuals. The data contain 18 demographic and clinical variables. To identify the statistical significant feature variables, the backwa...

Stability of discoidal high-density lipoprotein particles

Motivated by experimental and numerical studies revealing that discoidal high-density lipoprotein (HDL) particles may adopt flat elliptical and nonplanar saddle-like configurations, it is hypothesized that these might represent stabilized configurations of initially unstable flat circular particles. A variational description is developed to explore the stability of a flat circular discoidal HDL...

Study of Serum Paraoxonase and High Density Lipoprotein Fractions in Diabetes

Objective: Significant alteration in lipid profile and antioxidant system occurs in response to diabetes mellitus (DM). Paraoxonase (PON) is a family of three enzymes PON1, PON2 and PON3 associated with high density lipoprotein (HDL). The HDL in human plasma consists of two main sub-fractions HDL2C and HDL3C. We studied the HDL subclasses and HDL associated enzyme paraoxonase with respect to di...
