... the energy homeostasis system. In typical westernized diets, ω-6 polyunsaturated fatty acids (PUFAs) vastly exceed the amount of ω-3 PUFAs, with ω-6/ω-3 ratios ranging from 10:1 to 25:1. ω-6 PUFAs, such as arachidonic acid (AA), have ... effects and increase obesity.

... Dietary intervention involving omega-3 polyunsaturated fatty acids (ω-3 PUFAs) has emerged as a potential treatment. However, research investigating the relationship between ω-3, ω-6 PUFAs, and ω-6 to ω-3 ratio with inflammatory biomarkers remains controversial. Methods To investigate the correlation between the intake of ω-3 and ω-6 PUFAs and the ratio ...

In this study, soft ω-continuity and soft ω s -continuity are introduced as two new classes of soft functions, and several characterizations of these concepts are given.It is proven that soft ω-continuity is weaker than soft continuity and that soft ω s -continuity lies strictly between soft ω-continuity and soft semi-continuity.Sufficient conditions are introduced for the equivalence between soft ω s -continuity and soft ω-continuity, as well as that between soft ω s -continuity and soft semi-continuity.Furthermore, composition ...
