Omega-3 Polyunsaturated Fatty Acids (PUFAs): Emerging Plant and Microbial Sources, Oxidative Stability, Bioavailability, and Health Benefits-A Review.

The omega-3 (n-3) polyunsaturated fatty acids (PUFAs) eicosapentaenoic acid (EPA) and docosahexaenoic (DHA) acid are well known to protect against numerous metabolic disorders. In view of the alarming increase in the incidence of chronic diseases, consumer interest and demand are rapidly increasing for natural dietary sources of n-3 PUFAs. Among the plant sources, seed oils from chia (), flax (), and garden cress () are now widely considered to increase α-linolenic acid (ALA) in the diet.

Ascorbyl stearate stimulates cell death by oxidative stress-mediated apoptosis and autophagy in HeLa cervical cancer cell line in vitro.

In this study, Asc-s was evaluated for anti-cancer effect using cervical cancer cells (HeLa). Results determine that Asc-s treatment-induced dose-dependent inhibition of proliferation of HeLa cells and induced apoptosis. Flow-cytometry analysis shows Asc-s treatment-induced accumulation of cells at sub-G0/G1 stage of cell cycle and induced apoptosis as confirmed by DAPI, propodium iodide, and acridine staining in HeLa cells.

Ascorbyl stearate and ionizing radiation potentiate apoptosis through intracellular thiols and oxidative stress in murine T lymphoma cells.

Ascorbyl stearate (Asc-s) is a derivative of ascorbic acid with better anti-tumour efficacy compared to its parent compound ascorbic acid. In this study, we have examined radio-sensitizing effect of Asc-s in murine T cell lymphoma (EL4) cells at 4 Gy. Asc-s and radiation treatment reduced cell proliferation, induced apoptosis in a dose dependent manner by arresting the cells at S/G2-M phase of cell cycle.

Celecoxib, a COX-2 inhibitor, synergistically potentiates the anti-inflammatory activity of docosahexaenoic acid in macrophage cell line.

Background: The anti-inflammatory properties of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA) and non-steroidal anti-inflammatory drugs overlap in many ways. The aim of this study was to examine the individual and synergetic anti-inflammatory effects of celecoxib, EPA and DHA in RAW-264.7 cell line.

Medium-chain triglycerides and monounsaturated fatty acids potentiate the beneficial effects of fish oil on selected cardiovascular risk factors in rats.

Fish oil (FO) rich in eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) is known to reduce the risk of cardiovascular diseases (CVDs). Little information is known regarding the influence of lipid composition in the background diet on the modulatory effect of FO supplementation on CVDs. The present study was designed to investigate the influence of various background dietary lipids and FO on selected cardiovascular risk factors in rats.

Anti-platelet activity of water dispersible curcuminoids in rat platelets.

Curcuminoids are active principle of turmeric with plethora of health beneficial properties. In this study, we have evaluated for the first time the effect of water dispersible curcuminoids on rat platelet aggregation. Curcuminoids (10-30 µg/mL) significantly inhibited platelet aggregation induced by agonists viz.

Modulatory effect of α-linolenic acid-rich garden cress (Lepidium sativum L.) seed oil on inflammatory mediators in adult albino rats.

Vegetable oils containing α-linolenic acid (ALA; 18 : 3n-3) have been shown to modulate the functions of immunocompetent cells. The aim of the present study was to understand the modulatory effect of ALA-rich garden cress (Lepidium sativum L.) seed oil (GCO) on lipid composition, spleen lymphocyte (SL) proliferation and inflammatory mediator production by peritoneal macrophages (PMΦ) in rats.
