A Year of Science

Dear reader, from Fats of Life we wish you Happy Holidays! Another year comes to a close. Hundreds of new studies on polyunsaturated fatty acids have appeared this past year. In this issue of the Fats of Life Newsletter we highlight just four recent studies, nearly drops in the ocean of newly gathered knowledge on

Improving the Response Rate in Migraine Headache Attacks

This article at a glance This study addressed the potential effectiveness of daily EPA/DHA for migraine headaches in adults with chronic migraine also taking low-dose amitriptyline, a drug used for migraine prevention. Participants taking both EPA/DHA and amitriptyline for 2 months reported a major reduction in the frequency of headache attacks. The results of this

DHA – Are Memories Made of This?

This article at a glance The hippocampal-prefrontal cortex (H-PFC) pathway is a neuronal circuit that is central to integrating working memory with contextual information, facilitating executive function, such as making decisions. A recent neuroscience study in the rat reports that enzymatic conversion of DHA may underlie the regulation of synaptic plasticity in the H-PFC pathway.

Antimicrobial Defense Linked to the Hemostatic Response

This article at a glance This study reports that the coagulation of blood leads to the formation of arachidonic acid (AA)-, eicosapentaenoic acid (EPA)- and docosahexaenoic acid (DHA)-derived specialized proresolving mediators (SPMs) that promote microbial clearance. Clotting of human whole blood led to the formation of a distinct cluster of SPMs, namely lipoxin B4, resolvin

The Effect of Macronutrient Composition on Endogenous Long-Chain Polyunsaturated Fatty Acid Status during Weight Loss

This article at a glance The influence on tissue fatty acid composition of three different isocaloric diets  containing carbohydrates with a low glycemic index, carbohydrates with a high glycemic index, or a reduced fat content, respectively, was assessed in overweight-obese adults on a 500 kcal/d-energy restriction in a randomized controlled intervention trial. The study had

The Development of Chemoresistance: A New Immune Cell-Activating Mechanism Involving Uncommon Lipids that Mediate a Stem Cell Response to Genotoxicity

This article at a glance This study identifies the omega-3 polyunsaturated fatty acid hexadecatetraenoic acid (16:4 n-3) as a ligand of GPR120, a receptor studied for its role in regulating inflammation, energy metabolism and satiety. 16:4 n-3, previously identified as a fatty acid released by mesenchymal stem cells following the exposure to platinum-containing chemotherapeutic drugs,

The RvD1/LTB4 Ratio in Saliva – Assessing the Usefulness of an Innovative Biomarker for the Resolution of Inflammation in Vascular Disease.

This article at a glance The potential utility of the ratio of resolvin D1 (RvD1), a pro-resolving lipid mediator derived from DHA, to leukotriene B4 (LTB4), a pro-inflammatory mediator derived from AA, in saliva was determined to predict the level of non-resolving vascular inflammation. The study reports that patients with a higher carotid intima-media thickness
