Base is used broadly in both literal and figurative contexts: the wide base of the pyramid; a party seeking to expand its power base. Basis is used in a nonphysical sense: Healthy scepticism is the basis of all accurate observation (Arthur Conan Doyle).
Omega-3 fats also lower blood pressure and heart rate, improve blood vessel function, and, at higher doses, lower triglycerides and may ease inflammation, which plays a role in the development of atherosclerosis. Several large trials have evaluated the effect of fish or fish oils on heart disease.
Omega-6 (n-6) polyunsaturated fatty acids (PUFA) (e.g., arachidonic acid (AA)) and omega-3 (n-3) PUFA (e.g., eicosapentaenoic acid (EPA)) are precursors to potent lipid mediator signalling molecules, termed âeicosanoids,â which have important roles in the regulation of inflammation.
