To investigate the underlying mechanisms of C18 fatty acids (stearic acid, oleic acid, linoleic acid and α-linolenic acid) on mast cells, we measured the effect of C18 fatty acids on intracellular Ca(2+) mobilization and histamine release in RBL-2H3 mast cells. Stearic acid rapidly increased initial peak of intracellular Ca(2+) mobilization, whereas linoleic acid and α-linolenic acid gradually ...

The presence of medium-chain fatty acids in dietary fatty acid as well as the triacylglycerol structure may influence the absorption and lymphatic transport of fatty acids. We compared the lymphatic transport and recovery of fatty acids from four intragastrically administered fats based on rapeseed oil and decanoic acid in two rat models of normal absorption and malabsorption, respectively. The...

I . The fatty acid compositions of the plasma cholesteryl esters, phospholipids, triglycerides and unesterified fatty acids were determined in three sheep at various times after they had been given intra-abomasal infusions of emulsions of linseed oil, maize oil or linoleic acid. 2. The concentrations of linolenic acid or linoleic acid in the plasma triglycerides began to increase 1.5 h after in...

The article analyzes changes in the fatty acid composition of spring rapeseed represented by Trapper and Siberian varieties after their treatment with «Huminatrin» «Beres-8». cultivated region was studied gas-liquid chromatography. contains 19 acids a chain length 12 to 24 carbon atoms. preparations containing humic caused different reactions varieties. variety showed decrease oil content proce...

milk and dairy products are in diet almost every day. milk fat contains 70% of saturated fatty acids which can cause an increase in total and low-density lipoprotein cholesterol, and the risk of cardiovascular diseases. therefor, modification of fat composition at dairy products such as yoghurt seems necessary. walnut has high amount of essential fatty acids, anti oxidants and other beneficial ...

Radioiodinated fatty acids have been proposed as agents for use in heart imaging. Previous studies in experimental animals and humans using 131I-oleic acid of low specific activity were marginally successful. Higher specific activity compounds offer potential improvement for use as imaging agents for normal myocardium. Methods for preparation of high specific activity, radioiodinated fatty acid...

Lipid extract and fatty acid composition of cane molasses and yeasts (Saccharomyces cerevisiae M-300A and Saccharomyces uvarum IZ-1904) grown in molasses medium were determined. In molasses, linoleic acid was found in higher levels (around 42%) and was followed by palmitic, oleic and linolenic acids. The lipid extract varied from 1.02 to 3.13 gkg. In yeasts, the level of lipid extract varied fr...

The purpose of this research was to characterize an olive core collection using some agronomic characters and simple sequence repeat (SSR) markers and to determine SSR markers associated with the content of fatty acids in olive oil. SSR marker analysis demonstrated the presence of a high amount of genetic variation between the olive cultivars analyzed. A UPGMA dendrogram demonstrated that olive...

In the present intervention study we compared the effects of alpha-linolenic acid with those of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) on platelet aggregation in vitro and ex vivo in healthy non-institutionalized elderly subjects. We also compared the effects of alpha-linolenic acid on platelet aggregation in elderly subjects with those in younger volunteers. During a run-in...

Human red cell membrane Ca2+-stimulatable, Mg2+-dependent adenosine triphosphatase (Ca2+-ATPase) activity and its response to thyroid hormone have been studied following exposure of membranes in vitro to specific long-chain fatty acids. Basal enzyme activity (no added thyroid hormone) was significantly decreased by additions of 10(-9)-10(-4) M-stearic (18:0) and oleic (18:1 cis-9) acids. Methyl...
