A stable method for routine analysis of oxylipins from dried blood spots using ultra-high performance liquid chromatography–tandem mass spectrometry
In this study, we report the development and validation of a novel system for the quantitation of 21 individual oxylipins from a dried blood spot (DBS) using ultra-high performance liquid chromatography–tandem mass spectrometry (UHPLC–MS/MS) and stable isotope dilution analysis. Linearity and precision of the method were determined and the stabilities of the 12 most abundant oxylipins were tested during 2 months of storage at room temperature, after being spiked into blood and prepared as DBS on PUFAcoatTM paper. Responses were linear across the concentration range analysed for all oxylipins (r2 values ranged from 0.95...

Genetic Variant in the 3′-Untranslated Region of the COX2 Gene Is Associated with Type 2 Diabetes: A Hospital-Based Case-Control Study
In this study, we evaluated rs5275 and rs689466 variants located on the COX-2 gene by PCR-RFLP in 100 T2DM patients and 100 control subjects. The interaction among COX2 variants and T2DM was analyzed using appropriate methods. The both variants were in Hardy–Weinberg equilibrium in patients and controls (p>0.05). A significant association was observed for genotype distribution of COX2 rs5275 site between control and T2DM cases (p=0.042). In a dominant model, the cases who had at least one copy of allele C, were at increased risk of T2DM (p=0.016). We found no significant association for the COX2 rs689466 domain by evalua...

Dietary caprylic acid and ghrelin O-acyltransferase activity to modulate octanoylated ghrelin functions: what is new in this nutritional field?
Publication date: Available online 27 July 2018Source: Prostaglandins, Leukotrienes and Essential Fatty AcidsAuthor(s): Fanny Lemarié, Erwan Beauchamp, Gaëtan Drouin, Philippe Legrand, Vincent RiouxAbstractCaprylic acid (octanoic acid, C8:0) belongs to the class of medium-chain saturated fatty acids (MCFAs). Dairy products and specific oils such as coconut oil are natural sources of dietary caprylic acid. MCFAs display distinct chemico-physical and metabolic properties from those of long-chain saturated fatty acids (LCFAs ≥ 12 carbons) and potential beneficial physiological effects of dietary C8:0 have been studied for...

Dietary n-3 but not n-6 fatty acids down-regulate maternal dyslipidemia induced inflammation: A three-generation study in rats
This study addresses the effects of n-3 and n-6 fatty acids in maternal dyslipidemia induced inflammation over three generation in rats. The detailed protocol for animal feeding and mating is described in the methodology. Placenta and fetal liver were isolated on the eighteenth day of gestation and delivered pups after lactation were kept on their maternal diets. Compared to control and experimental groups, high-fat fed rats (HFL) had a higher level of cytokines and eicosanoids in serum (p < 0.05). Liver and uterine expression of cPLA-2, Cox-2, 5-Lox, EP-1, BLT-1, and ICAM-1 were higher (p < 0.05) in HFL gr...

N-docosahexaenoylethanolamine detected in human breast milk
Conclusion: This is the first demonstration of detectable concentrations of synaptamide in human breast milk. Although the attempt to raise the milk DHA content by omega-3 fatty acid supplementation was not successful in the current study, the positive correlation observed between synaptamide and DHA concentration suggests that synaptamide levels in human milk can be raised by proper omega-3 fatty acid supplementation that is known to increase DHA.

Concentrations of oxidized linoleic acid derived lipid mediators in the amygdala and periaqueductal grey are reduced in a mouse model of chronic inflammatory pain
In this study, we employed a mouse model of chronic inflammatory pain followed by a targeted lipidomic analysis of the animals’ amygdala and periaqueductal grey (PAG) using LC-MS/MS to investigate the effect of chronic inflammatory pain on oxylipin concentrations in these two brain nuclei known to participate in pain sensation and perception. From punch biopsies of these brain nuclei, we detected twelve OXLAMs in both the PAG and amygdala and one arachidonic acid derived mediator, 15-HETE, in the amygdala only. In the amygdala, we observed an overall decrease in the concentration of the majority of OXLAMs detected, while...

Stearidonic Acid Combined with Alpha-Linolenic Acid Improves Lipemic and Neurological Markers in a Rat Model Subject to a Hypercaloric Diet
In this study, we hypothesized that terrestrial plant oils, rich in alpha linolenic acid (ALA) and stearidonic acid (SDA) relative to fish oil, rich in eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), prevent negative effects on cardiovascular and neurological function using a rat model fed a hypercaloric diet. Results showed effects on the FA profile, namely, eicosapentaenoic, EPA, and docosahexaenoic, DHA, levels. There were also effects on neural aspects (cAMP response element-binding protein, CREB, gene expression, at least, doubled) and the pro-inflammatory/anti-inflammatory balance (TNF-α, tumor necrosis ...

Role of metabolic programming in the modulation of microglia phagocytosis by lipids
Publication date: August 2018Source: Prostaglandins, Leukotrienes and Essential Fatty Acids, Volume 135Author(s): A. NadjarAbstractMicroglia phagocytosis is an essential process to maintain lifelong brain homeostasis and clear potential toxic factors from the neuropil. Microglia can engulf cells or part of cells through the expression of specific receptors at their surface and activation of downstream signaling pathways to engulf material. Microglia phagocytosis is finely regulated and is under the dependence of many factors, including environmental cues such as dietary lipids. Yet, the molecular mechanisms implicated are ...
