A mixture of eight fatty acids (linoleic, oleic, palmitic, stearic, myristic, elaidic, lauric, and palmitoleic acids) at similar concentrations that have been identified in human amniotic fluid exerts anxiolytic-like effects similar to diazepam in adult Wistar rats through actions at γ-aminobutyric acid-A (GABAA) receptors, but unknown is whether any of these fatty acids exerts a predominant ac...

Fatty acids (C6-C18) found in human amniotic fluid, colostrum, and maternal milk reduce behavioral indicators of experimental anxiety in adult Wistar rats. Unknown, however, is whether the anxiolytic-like effects of fatty acids provide a natural mechanism against anxiety in young offspring. The present study assessed the anxiolytic-like effect of a mixture of lauric acid, myristic acid, palmiti...

Human amniotic fluid and a mixture of eight fatty acids (FAT-M) identified in this maternal fluid (C12:0, lauric acid, 0.9 μ g%; C14:0, myristic acid, 6.9 μ g%; C16:0, palmitic acid, 35.3 μ g%; C16:1, palmitoleic acid, 16.4 μ g%; C18:0, stearic acid, 8.5 μ g%; C18:1 cis, oleic acid, 18.4 μ g%; C18:1 trans, elaidic acid, 3.5 μ g%; C18:2, linoleic acid, 10.1 μ g%) produce anxiolytic-like effects ...

Excess consumption of trans-fatty acid could increase the risk of non-alcoholic steatohepatitis (NASH); however, treatment targeting trans-fatty acid-induced NASH has not been examined. Here we focused on the influence of trans-fatty acid intake on endoplasmic reticulum (ER) stress in hepatocytes, so we investigated the effect of the chemical chaperone 4-phenylbutyric acid (PBA), on trans-fatty...

BACKGROUND Low attention to dairy product consumptions and high intake of junk foods and bakery products might be related to high prevalence of chronic diseases because of their fat content and fatty acid composition. OBJECTIVE In this study we investigated the kind and amount of fatty acid content in Iranian junk foods, dairy, and bakery products. MATERIALS AND METHODS Some common brands o...

alpha-Hydroxy-9-cis-octadecenoic acid, a synthetic fatty acid that modifies the composition and structure of lipid membranes. 2-Hydroxyoleic acid (HOA) generated interest due to its potent, yet nontoxic, anticancer activity. It induces cell cycle arrest in human lung cancer (A549) cells and apoptosis in human leukemia (Jurkat) cells. These two pathways may explain how HOA induces regression of ...

We have recently reported that lipid structure regulates the interaction with membranes, recruitment to membranes, and distribution to membrane domains of heterotrimeric Galphabetagamma proteins, Galpha subunits, and Gbetagamma dimers (J Biol Chem 279:36540-36545, 2004). Here, we demonstrate that modulation of the membrane structure not only determines G protein localization but also regulates ...

2H NMR techniques have recently been developed to determine the complete orientational order profile of lipid bilayers employing lipids containing perdeuteriated palmitic acid [Lafleur, M., Fine, B., Sternin, E., Cullis, P.R., & Bloom, M. (1989) Biophys. J. 56, 1037-1041]. In this work, these techniques have been applied to study order profiles in intact membranes derived from Acholeplasma laid...

Changes in slope of Arrhenius plots for transport can, in some instances, be detected at two different temperatures for cells that have a relatively simple fatty-acid composition in the membrane lipids. These characteristic temperatures correlate with the characteristic temperatures that define changes of state in membrane phospholipids as revealed by the paramagnetic resonance of the spin labe...
