The effects of eicosapentaenoic acid (EPA) and a new dihydropyridine calcium antagonist isradipine on plasma cholesterol free fatty acids (FFA) and erythrocytes have been studied in 48 cholesterol-fed rabbits after 3-month experiment. EPA had no statistically significant reduction of total cholesterol, FFA but showed the accumulation of cholesterol in plasma and altered morphological and functional properties of erythrocytes. Isradipine revealed a dose-dependent reduction of hypercholesterolemia. levels of FFA in plasma and improved functions of erythrocytes. In this way EPA may be suitable for dietary treatment of atherosclerosis, while isradipine may be used for therapy of patients with an antisclerotic vascular system and hyperlipidemia.

Aspartate (Asp) metabolism-mediated antioxidant functions have important implications for neonatal growth and intestinal health; however, the antioxidant mechanisms through which Asp regulates the gut microbiota and influences RIP activation remain elusive. This study reports that chronic oxidative stress disrupts gut microbiota and metabolite balance and that such imbalance is intricately tied to the perturbation of Asp metabolism. Under normal conditions, in vivo and in vitro studies reveal that exogenous Asp improves intestinal health by regulating epithelial cell proliferation, nutrient uptake, and apoptosis.
