Abstract

The biological effects of oxidized LDL (oxLDL) may contribute to initiation and progression of the atherosclerotic process, and the association between cardiovascular disease and oxidation of LDL has been largely demonstrated. The objectives of this study were to establish the reference values of oxidative stress biomarkers in a young healthy Spanish population to determine the concentration of oxLDL and its relationship with lipid profile and with these biomarkers. oxLDL, F(2)-isoprostanes, protein carbonyls (PC), and 8-hydroxy-2'-deoxyguanosine (8-OHdG) were determinate by ELISA in 72 healthy subjects. Antioxidant enzymes, superoxide dismutase (SOD), glutathione peroxidase (GPx), and glutathione reductase (GR) were carried out on a Hitachi 912 analyzer; lipid profile were assayed using automated systems (Cobas 711, Roche Diagnostics). All statistics were analyzed by using SPSS for Windows 15.0. SPSS Inc, Chicago, IL, USA. (Normal mean reference values): oxLDL (63.23 +/- 16.23 U/L), (Male/Female 68.06 +/- 17.69/58.39 +/- 13.6 U/L), F(2)-isoprostanes (2.26 +/- 0.9 microg/g creatinine), PC (0.34 +/- 0.15 nmol/mg), 8-OHdG (23.27 +/- 10.58 ng/ml), SOD (931.97 +/- 271.09 U/g Hb), GR (46.56 +/- 11.68 U/L), GPx (27.58 +/- 6.89 U/gHb ...Continue Reading

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.
