Lipidomic analysis of surfactant and plasma from horses with asthma and age-matched healthy horses.

Objective: To perform lipidomic analysis of surfactant and plasma from asthmatic and healthy horses.

Animals: 30 horses with clinical signs of asthma and 30 age-matched control horses.

Procedures: Detailed history, physical examination, CBC, and bronchoalveolar lavage fluid (BALF) cytologies were obtained.

Dynamics of DHA and EPA supplementation: incorporation into equine plasma, synovial fluid, and surfactant glycerophosphocholines.

Introduction: Horses with asthma or osteoarthritis frequently receive ω-3 fatty acid supplements. Docosahexaenoic (DHA; 22:6) and eicosapentaenoic (EPA; 20:5) acids are essential ω-3 fatty acid precursors of anti-inflammatory mediators and components of structural glycerophospholipids (GPL) that act as reservoirs of these fatty acids. Analysis of the incorporation of dietary DHA + EPA into GPL pools in different body compartments has not been undertaken in horses.

Lipidomics of the chicken egg yolk: high-resolution mass spectrometric characterization of nutritional lipid families.

While previous studies have characterized the fatty acids and global lipid families of the chicken egg yolk, there have been no publications characterizing the individual lipids in these lipid families. Such an in-depth characterization of egg yolk lipids is essential to define the potential benefits of egg yolk consumption for the supply of structural and anti-inflammatory lipids. Historically, the major focus has been on the cholesterol content of eggs and the potential negative health benefits of this lipid, while ignoring the essential roles of cholesterol in membranes and as a precursor to other essential sterols.
