Anti-Atherosclerotic Effect of a Polyphenol-Rich Ingredient, Oleactiv
2018
The development of nutraceutical ingredients has risen as a nutritional solution for health prevention. This study evaluated the effects of Oleactiv®, an ingredient developed for the prevention of atherogenesis, in hypercholesterolemic hamsters. Oleactiv® is a polyphenol-rich ingredient obtained from artichoke, olive and grape extracts as part of fruit and vegetables commonly consumed within the Mediterranean diet. A total of 21 Golden Syrian hamsters were divided into three groups. The standard group (STD) was fed a normolipidemic diet for 12 weeks, while the control group (CTRL) and Oleactiv® goup (OLE) were fed a high-fat diet. After sacrifice, the aortic fatty streak area (AFSA), plasma…
The Participation of the Complement System in Atherosclerotic Vascular Disease
1991
Atherosclerosis is a vascular disease of large and medium-sized arteries wherein the tunica intima becomes thickened due to lipid accumulation, mostly cholesterol and its esters, smooth muscle cell proliferation, and increased deposition of connective tissue matrix. A major risk factor in the development of this disease is hypercholesterolemia arising from elevated levels of low density lipoproteins (LDL). The earliest recognizable lesion, which may be a precursor to the fibrofatty plaque, is the fatty streak. It is predominantly composed of monocyte-derived macrophage foam cells, i.e. cells ladened with intracellular lipid droplets. Hence, a fundamental aspect of atherogenesis is the insud…
