Polyunsaturated Fatty Acids and Their Correlations with Parameters of Oxidative/Antioxidant Potential of the Blood and Lipoprotein-Associated Phospholipase A2 in Coronary Atherosclerosis.

We studied serum content of some polyunsaturated fatty acids and their correlations with parameters of oxidative stress (FORT), antioxidant protection (FORD), lipoprotein-associated phospholipase A2 (LP-PLA2), and serum level of LPO products in male patients with coronary atherosclerosis. The mass fraction of polyunsaturated fatty acids and FORD were lower, while LP-PLA2, FORT, and concentration of LPO products were higher than in the control group (conventionally healthy men). Negative correlations of medium strength of polyunsaturated fatty acids with inflammation markers and oxidative stress were revealed, which can indicate that the decrease in polyunsaturated fatty acids content is associated with enhanced generation of free radicals, and consequently with increased risk of early atherosclerosis development.

Associations of Osteocalcin, Osteoprotegerin, and Calcitonin with Inflammation Biomarkers in Atherosclerotic Plaques of Coronary Arteries.

We studied associations of osteocalcin, osteoprotegerin, and calcitonin with markers of inflammation in atherosclerotic plaques in coronary arteries and assessed the influence of these biomolecules on calcification of atherosclerotic plaques. The initial stage of calcification of atherosclerotic plaques is characterized by activation of inflammatory processes, which is seen from increased levels of proinflammatory biomarkers (IL-6, IL 8, TNF-α, and IL-1β). Progressive calcification of atherosclerotic plaques is accompanied by insignificant accumulation of calcitonin and osteoprotegerin.
