Polyunsaturated fatty acid (PUFA) rich micro-algal oil was tested in vitro and compared with fish oil for antiproliferative properties on cancer cells in vitro. Oils derived from Crypthecodinium cohnii, Schizochytrium sp. and Nitzschia laevis, three commercial algal oil capsules, and menhaden fish oil were used in cell viability and proliferation tests with human colon adenocarcinoma Caco-2 cells. With these tests no difference was found between algal oil and fish oil. The nonhydrolysed algal oils and fish oil showed a much lower toxic effect on cell viability, and cell proliferation in Caco-2 cells than the hydrolysed oils and the free fatty acids (FFAs). Eicosapentaenoic acid (EPA; C20:5n-3) and docosahexaenoic acid (DHA; C22:6n-3) were used as samples for comparison with the tested hydrolysed and nonhydrolysed oils. The hydrolysed samples showed comparative toxicity as the free fatty acids and no difference between algal and fish oil. Oxidative stress was shown to play a role in the antiproliferative properties of EPA and DHA, as alpha-tocopherol could partially reverse the EPA/DHA-induced effects. The results of the present study support a similar mode of action of algal oil and fish oil on cancer cells in vitro, in spite of their different PUFA content.

The discharge of oil-laden wastewater from industrial processes and the frequent occurrence of oil spills pose severe threats to the ecological environment and human health. Membrane materials with special wettability have garnered attention for their ability to achieve efficient oil-water separation by leveraging the differences in wettability at the oil-water interface. These materials are characterized by their simplicity, energy efficiency, environmental friendliness, and reusability.

Enhanced inflammatory and immune responses have been observed in patients with major depressive disorder, pointing to anti-inflammatory substances as potential seeds for developing novel antidepressants. Omega-3 polyunsaturated fatty acid metabolites, such as resolvin D and E series, maresins, and protectins (collectively known as specialized pro-resolving mediators) demonstrate anti-inflammatory effects. This study examined the antidepressant-like effects of maresin-1 (MaR1) on lipopolysaccharide (LPS)-induced depression-like behaviors in mice.

Atopic dermatitis (AD), also known as eczema, is a chronic or relapsing inflammatory skin disease characterized by repeated exacerbations and remissions. Here, we investigated the effects of squid phospholipids (PLs) extracted from Todarodes pacificus on AD. The composition of squid PLs was analyzed using thin-layer chromatography and high-performance liquid chromatography, and the effects of PLs on AD were investigated using a rat paw edema model and an AD-like mouse model (NC/Nga mice).
