Children patients with alterative-exudative (gastrointestinal diseases) and allergic inflammation (bronchial asthma) exhibited similar changes in fatty acid composition of erythrocyte and leukocyte membranes. They included accumulation of considerable amounts of eicosapentaenoic acid and decrease in the content of docosahexaenoic acid (long-chain derivative of eicosapentaenoic acid). The accumulation of eicosapentaenoic acid and decrease in the content of docosahexaenoic acid in cell membranes probably play a role in the pathogenesis of chronic inflammatory diseases. It is related to a possible decrease in the formation of anti-inflammatory eicosanoids (series-5 leukotrienes) and protective compounds (resolvins and protectins) from fatty acids and changes in the physicochemical properties of cell membranes.

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).

Introduction: Long-term fasting (LF) activates an adaptative response to switch metabolic fuels from food glucose to lipids stored in adipose tissues. The increase in free fatty acid (FFA) oxidation during fasting triggers health benefits. We questioned if the changes in lipid metabolism during LF could affect lipids in cell membranes in humans.

Recently, the biosynthesis of omega-3 fatty acids (ω3 FAs) in yeast has witnessed significant advancements. Notably, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) play crucial roles in overall human growth, encompassing neurological development, cardiovascular health, and immune function. However, traditional sources of ω3 FAs face limitations such as environmental concerns.

The synthesis of n-3 and n-6 polyunsaturated acids (PUFAs) is associated with physiological functions in mammals, being catalyzed by Δ-5D and Δ-6D desaturases and elongases Elovl-2 and Elovl-5. In this context, we aimed to study the chief kinetic features of PUFA liver anabolism, looking upon (i) the time-dependency for the specific activity of Δ-6D, Δ-5D, Elovl2, Elovl2/5 and Elovl5, using n-3 and n-6 precursors between 0 and 240 min ex vivo in mouse liver.; and (ii) the specific activity-substrate (α-linolenic acid; ALA) concentration responses of Δ-6D in the absence and presence of linoleic acid (LA), arachidonic acid (ARA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), an enzyme regarded as the rate-limiting step in PUFA anabolism.

: Sudden cardiac death (SCD) poses a significant burden on the modern-day public health system; however, while our understanding of the underlying pathophysiology is still evolving and may not be complete, many insights are known and applied every day. Targeted prevention methods are continually being developed and refined. We conducted a systemic review and meta-analysis to identify a blood nutritional biomarker that can predict and screen population groups at high risk for cardiovascular disease mortality (CVD mortality) or SCD.
