BACKGROUND Fatty acids (FA) and their metabolites are closely related to some mechanisms involved in the development of uronephrolithiasis. The aim of this study was to evaluate the relationship between FA composition and type of kidney stones. MATERIAL AND METHODS Abdominal adipose tissue fatty acid methyl esters of 71 men with nephrolithiasis were identified by GC/MS, and the type of kidney s...

Consumption of a Western diet rich in saturated fats is associated with obesity and insulin resistance. In some insulin-resistant phenotypes this is associated with accumulation of skeletal muscle fatty acids. We examined the effects of diets high in saturated fatty acids (Sat) or n-6 polyunsaturated fatty acids (PUFA) on skeletal muscle fatty acid metabolite accumulation and whole-body insulin...

Consumers are increasingly becoming more aware of the relationships between diet and health. The functional–food components of beef and milk fat include ω–3 polyunsaturated fatty acids (PUFA) and conjugated linoleic acid (CLA). Beef typically has high saturated fatty acid content and low PUFA content, but the content of beneficial fatty acids can be increased by dietary manipulation. Dietary li...

Polyunsaturated fatty acids (PUFAs) affect cardiac excitability. Kv7.1 and the β-subunit KCNE1 form the cardiac IKs channel that is central for cardiac repolarization. In this study, we explore the prospects of PUFAs as IKs channel modulators. We report that PUFAs open Kv7.1 via an electrostatic mechanism. Both the polyunsaturated acyl tail and the negatively charged carboxyl head group are req...

In this study, total fatty acid composition of muscle lipids of Cyprinus carpio L. living in Suğla Dam Lake, Altinapa Dam Lake, Eğirdir Lake and Burdur Lake were determined using GC. During this study, for the summer season of July was taken from each region of the land and they were stored in deep-freeze set to -20 degrees until the analysis date. At the end of the analyses, 30 different fatty...

Postprandial plasma insulin concentrations after a single high-fat meal may be modified by the presence of specific fatty acids although the effects of sequential meal ingestion are unknown. The aim of the present study was to examine the effects of altering the fatty acid composition in a single mixed fat-carbohydrate meal on glucose metabolism and insulin sensitivity of a second meal eaten 5 ...

Dietary polyunsaturated fat is known to suppress expression of fatty acid synthase (FAS), a central enzyme in de novo lipogenesis. The sterol regulatory element-binding protein (SREBP) has recently been shown to be involved in this suppression. We previously reported that the first 2.1 kb of the FAS promoter are sufficient for transcriptional induction by a high carbohydrate diet as well as sup...

Owing to the favorable effects of essential fatty acids on human health, a great degree of interest on fatty acid profiles and nutritional quality of fish species have been of interest in the recent years. The present study investigated the lipid content, fatty acid profiles and nutritional quality in nine freshwater fish species from the Ganjiang River in the Yangtze basin, China. Results show...

It has been demonstrated in animal studies that polyunsaturated fatty acids (PUFA) prevent ischemia-induced malignant ventricular arrhythmias, a major cause of sudden cardiac death in humans. To learn how these PUFA, at low micromolar concentrations, exert their antiarrhythmic activity, we studied their effects in vitro on the contractions of isolated cardiac myocytes and the conductances of th...

Polyunsaturated fatty acids (PUFAs), primarily docosahexaenoic acid (DHA) and eicosapentaenoic (EPA), have received worldwide attention in recent years due to an increasing awareness of their uniqueness improving diet human health apparently inevitable shortage global availability. Microbial cell factories are a major solution supplying these precious molecules sufficient amounts providing PUFA...
