The purpose of this study was to examine the effect of 0-50 micromol/L trans-10, cis-12 conjugated linoleic acid (CLA) and cis-9, trans-11 CLA isomers on lipid and glucose metabolism in cultures of differentiating 3T3-L1 preadipocytes. Specifically, we investigated the effects of 6 d of CLA treatment on the following: 1) (14)C-glucose and (14)C-oleic acid incorporation and esterification into l...

The palladium(II) complexes trans-[PdCl(L)(PPh3)2]Cl, 5, and cis-[PdI2(L)PPh3], 7, (L = benzoxazol-2-ylidene) have been synthesized by treatment of the complexes trans-[PdX2(PPh3)2] (4: X = Cl, 6: X = I) with 2-(trimethylsiloxy)phenyl isocyanide 1, and subsequent hydrolysis of the Si-O bond. The crystal structures of 5 and 7∗CH2Cl2 were established by X-ray diffraction. NMR and IR studies indic...

OBJECTIVE To determine the effects of 2 conjugated linoleic acid (CLA) isomers (cis-9, trans-11 and trans-10, cis-12) on synthesis of prostaglandin (PG) E(2) and F(2α) and expression of prostaglandin H synthase-2 (PGHS-2) of adult and fetal bovine endometrial epithelial cells in vitro. SAMPLE Primary cultures of endometrial epithelial cells obtained from 4 adult cows and 4 fetal bovine carcas...

This study reports, for the first time, chemical composition and biological activity of essential oil from Brazilian Cymbopogon densiflorus flowers. Thirty compounds were identified by gas chromatography coupled with mass spectrometry (GC/MS), corresponding to 95 % total an chromatogram obtained chromatography-flame ionization detection (GC-FID ). The was mainly composed cis-p-mentha-1(7),8-die...

background: reactive oxygen species (ros) have important role in the etiology and pathogenesis of rheumatoid arthritis (ra). we investigated the effect of conjugated linoleic acids (clas) and vitamin e on lipid peroxidation. methods: in a randomized, double-blind placebo, controlled, clinical trial 87 patients with active ra were enrolled. they were divided into 4 groups, received one of the fo...

The synthesis, characterization, and cytotoxicity of eight new platinum(IV) complexes having the general formula cis,cis,trans-[Pt(NH(3))(2)Cl(2)(O(2)CNHR)(2)] are reported, where R = tert-butyl (4), cyclopentyl (5), cyclohexyl (6), phenyl (7), p-tolyl (8), p-anisole (9), 4-fluorophenyl (10), or 1-naphthyl (11). These compounds were synthesized by reacting organic isocyanates with the platinum(...

Thirty lactating dairy cows were used in a 3 × 3 Latin-square design to investigate the effects of a raw or extruded blend of linseed and wheat bran (70:30) on plasma and milk fatty-acids (FA). Linseed diets, containing 16.6% linseed blend on a dry-matter basis, decreased milk yield and protein percentage. They decreased the proportions of FA with less than 18 carbons in plasma and milk and res...

The ratio of cis and all-trans lycopene (LYC) in human and animal tissues exceeds that in foods. The basis for this difference remains unknown, although differences in their stability, transport, and metabolism have been suggested. Here, we systematically compared the digestive stability, efficiency of micellarization, and uptake and intracellular stability of cis and all-trans isomers of LYC a...

Fullerenes are reactive as dienophiles in Diels–Alder reactions. Their distinctive molecular shape and properties result interesting sometimes elusive reaction patterns. Herein, to contribute the understanding of fullerene reactivity, we evaluate energies reactions for cycloadditions C60, C70, IC60MA with anthracene (Ant), by means DFT computational analysis vacuum solution. The methods used sh...

1. Propetamphos is an organophosphorus compound. Technical grade propetamphos consists of 4 isomers, 2 geometric (cis and trans) isomers and 2 optical (Sand R-)isomers. The cis form predominates as the active ingredient, usually exceeding 90% w/w of the technical material. From analogy with the chiral separation of propetamphos-oxon, cis-propetamphos is a racemate of equal proportions of the Sa...
