Vaccenic and elaidic acid modify plasma and splenocyte membrane phospholipids and mitogen-stimulated cytokine production in obese insulin resistant JCR:LA-cp ratsDownload
This study assessed the long-term effects of dietary vaccenic acid (VA) and elaidic acid (EA) on plasma and splenocyte phospholipid (PL) composition and related changes in inflammation and splenocyte phenotypes and cytokine responses in obese/insulin resistant JCR:LA-cp rats. Relative to lean...
Vaccenic acid suppresses intestinal inflammation by increasing the endocannabinoid anandamide and non-cannabinoid signaling molecules in a rat model of the metabolic syndromeDownload
Jacome-Sosa, Miriam, Proctor, Spencer D., Field, Catherine J., Vacca, Claudia, Nelson, Randy C., Mangat, Rabban, Reaney, Martin J., Curtis, Jonathan M., Banni, Sebastiano, Diane, Abdoulaye, Piomelli, Daniele, Igarash, Miki, Vine, Donna F., Shen, Jianheng
Vaccenic acid (VA), the predominant ruminant-derived trans fat in the food chain, ameliorates hyperlipidemia, yet mechanisms remain elusive. We investigated whether VA could influence tissue endocannabinoids (ECs) by altering the availability of their biosynthetic precursor, arachidonic acid...
Vaccenic acid (VA) is a ruminant-derived trans-fat and precursor of conjugated linoleic acid (CLA). The objective of the present study was to explore the effects of VA on immune function in a model of the metabolic syndrome, JCR:LA-cp rats. Lean (2:1 mix of +/cp and +/+) and obese (cp/cp) rats,...
Understanding postprandial inflammation and its relationship to lifestyle behaviour and metabolic diseasesDownload
Postprandial hyperlipidemia with accumulation of remnant lipoproteins is a common metabolic disturbance associated with atherosclerosis and vascular dysfunction, particularly during chronic disease states such as obesity, the metabolic syndrome and, diabetes. Remnant lipoproteins become attached...
Separation and quantitation of apolipoprotein B48 and other apolipoproteins by dynamic sieving capillary electrophoresisDownload
Apolipoprotein-B-48 is a structural protein exclusively associated with post-prandial lipoproteins (chylomicrons). Apolipoprotein B-48 would be a useful marker to monitor the kinetics of chylomicrons in vivo, however, its quantitation is limited because of a low concentration in plasma and lack...
Catheterization of the intestinal lymph trunk in neonatal pigs is a technique allowing for the long-term collection of large quantities of intestinal (central) efferent lymph. Importantly, the collection of central lymph from the intestine enables researchers to study both the mechanisms and...
Over the past 20 years, a growing amount of evidence supports the role of microbes and an imbalanced microbiota in inflammatory bowel disease (IBD). While many reviews have been written on the microbiota in IBD, few have considered how they fulfil the Koch's postulates. In this review, we...
Insulin and testosterone are associated with elevated intestinal secretion of lipids and lipoproteins in a rodent model of the metabolic and polycystic ovary syndromeDownload
The metabolic syndrome is highly associated with the incidence of Polycystic Ovary Syndrome (PCOS). The metabolic aberrations of insulin resistance and hyperandrogenemia have been proposed to contribute to the development of dyslipidemia and increased Cardiovascular Disease (CVD) risk in PCOS....
Increased hypolipidemic benefits of cis-9, trans-11 conjugated linoleic acid in combination with trans-11 vaccenic acid in a rodent model of the metabolic syndrome, the JCR:LA-cp ratDownload
Background Conjugated linoleic acid (cis-9, trans-11 CLA) and trans-11 vaccenic acid (VA) are found naturally in ruminant-derived foods. CLA has been shown to have numerous potential health related effects and has been extensively investigated. More recently, we have shown that VA has...
Improving beef hamburger quality and fatty acid profiles through dietary manipulation and exploitation of fat depot heterogeneityDownload
Background Hamburger is the most consumed beef product in North America, but lacks in nutritional appeal due to its high fat content and high proportion of saturated fatty acids (SFA). Objectives of the present study were to improve the FA profiles of hamburgers made with perirenal fat (PRF) and...
