This study was carried out to investigate the effect of different cooking techniques applied meats on total CLAs, cis-9,trans-11-CLA (c9,t11-CLA) and trans-10,cis-12-CLA (t10,c12-CLA). . In study, four methods such as boiling, frying, baking grilling were meat samples taken from bovine carcasses. raw cooked samples, CLA, cis-9, trans-11 trans-10, cis-12 isomer amounts examined in Gas Chromatogr...

This study compared the growth inhibitory effects of pure conjugated linoleic acid (CLA) isomers [cis(c)9,c11-CLA, c9,trans(t)11-CLA, t9,t11-CLA, and t10,c12-CLA] on human colon cancer cell lines (Caco-2, HT-29 and DLD-1). When Caco-2 cells were incubated up to 72 h with 200 microM, each isomer, even in the presence of 10% fetal bovine serum (FBS), cell proliferation was inhibited by all CLA is...

The c9,t11-18:2 isomer of conjugated linoleic acid (c9,t11-CLA) represents the main dietary CLA form with putative health benefits. Whereas CLA intake influences the tissue CLA concentration, little is known about the association between dietary CLA and the CLA content of plasma lipid fractions. This study was designed to document fasting and nonfasting plasma c9,t11-CLA concentrations in a pop...

The effects of dietary conjugated linoleic acid (CLA) on lipid concentrations and fatty acid composition of various tissues were studied in young chicks. From 7 days of age, a total of 160 chicks were divided into 4 groups, placed into 4 pens per group (10 birds per pen) and fed one of four experimental diets containing 6% tallow (TO 6%), 4% tallow plus 2% CLA (TO 4%-CLA 2%), 2% tallow plus 4% ...

There is no consensus about the effects of conjugated linoleic acid (CLA) on lipid metabolism, especially in animals fed a high-fat diet. Therefore, the objective of the present study was to evaluate the incorporation of CLA isomers into serum, liver and adipose tissue, as well as the oxidative stress generated in rats refed with high-fat diets after a 48 hour fast. Rats were refed with diets c...

BACKGROUND & OBJECTIVES Conjugated linoleic acid (CLA) reduces fat deposition in the body, but the mechanism of action is not clear. The present study was conducted to investigate the effects of CLA on body fat metabolism. Since milk fat is the best natural source of dietary CLA, intervention of non-fat milk constituents on CLA treatment was also investigated. METHODS Diets containing CLA (1%...

We reviewed the literature regarding the effects of conjugated linoleic acid (CLA) preparations enriched in specific isomers, cis9, trans11-CLA (c9, t11-CLA) or trans10, cis12-CLA (t10, c12-CLA), on tumorigenesis in vivo and growth of tumor cell lines in vitro. We also examined the potential mechanisms by which CLA isomers may alter the incidence of cancer. We found no published reports that ex...

Our aim was to assess the effect of two isomers of conjugated linoleic acids (CLA), cis-9,trans-11-CLA (c9,t11-CLA) and trans-10,cis-12-CLA (t10,c12-CLA), on glucose metabolism and hepatic expression of NR4A receptors, key transcription factors regulating gluconeogenesis. ApoE-deficient mice were fed isocaloric, isonitrogenous westernized diets enriched with c9,t11-CLA, t10,c12-CLA or linoleic ...

Conjugated linoleic acid (CLA) reduces body fat reserves, and reduces atherogenesis and type II diabetes in animal experiments. It has been reported that CLA have isomeric-specificity, such as c9, t11 CLA with anticancer activity. The antiproliferative effects of two isomers of CLA (c9, t11-CLA, t9, t11-CLA) and their mixture on the human colon adenocarcinoma cell line Caco-2 were investigated ...

The objective of this experiment was to determine the effects of dietary lipid source with or without the addition of CLA on bacon composition and quality. Forty-eight barrows at a beginning BW of 55 kg +/- 2.2 were fed 1 of 6 diets for 56 d. These diets consisted of: 1) normal corn (NC), 2) NC + 1.25% CLA-60 oil (NC + CLA), 3) high-oil corn (HOC), 4) HOC + 1.25% CLA-60 oil (HOC-CLA), 5) NC + c...
