The cellular toxicity of nanoparticles that were capped with a bilayered ligand was studied using an up-converting (UC) phosphor material as a representative nanoparticle (NP). The results indicate that although UC NPs are known to be nontoxic, the toxicity of the NPs depends strongly on ligand coordination conditions, in addition to the other commonly known parameters such as size, structure, ...

Oleate content is important for the nutritional value and oxidative stability of soybean [Glycine max (L.) Merr.] seed oil. Response to selection for higher oleate content depends on its heritability in breeding populations, and correlated responses of other fatty acid and agronomic traits to selection for oleate content depend on their genetic correlations with oleate. The objective of this st...

BACKGROUND Several translational studies have identified the differential role between saturated and unsaturated fatty acids at cardiovascular level. However, the molecular mechanisms that support the protective role of oleate in cardiovascular cells are poorly known. For these reasons, we studied the protective role of oleate in the insulin resistance and in the atherosclerotic process at cell...

The incorporation of cholesteryl oleate and triolein into phospholipid vesicles was studied in cosonicated mixtures of 94 weight % egg phosphatidylcholine and 6 weight % neutral lipid (0-6% triolein and 6-0% cholesteryl oleate). 13C NMR spectroscopy was used to quantitate both neutral lipids in vesicles containing 90% isotopically substituted [carbonyl-13C]cholesteryl oleate and [carbonyl-13C]t...

The association between metabolic diseases and the risk of developing cancer is emerging. However, the impact of long pentraxin-3 (PTX3) on dyslipidemia-associated tumor metastasis remains unknown. In this study, we found that oleate induced PTX3 expression and secretion through the activation of Akt/NF-κB pathway in head and neck squamous cell carcinomas (HNSCCs). The activation of NF-κB was e...

A membrane-bound oleyl coenzyme A desaturase from maturing Carthumus tinctorius seeds specifically catalyzed the conversion of oleyl-CoA to linoleyl-CoA. Any modification of the substrate, that is, a trans double bond, a shift in the position of the cis double bond, chain length, and the substitution of acyl carrier protein for CoA as the thioester moiety resulted in complete loss of activity. ...

A chiral amino acid-based monomeric and polymeric surfactant, sodium oleyl-L-leucylvalinate) (L-SOLV) and poly(sodium oleyl-L-leucylvalinate) (poly-L-SOLV) were synthesized and used for chiral separations in micellar electrokinetic chromatography (MEKC). Poly-L-SOLV was used successfully in the separation of various enantiomers of neutral, acidic, and basic analytes such as 1,1'-bi-2-napthol, 1...

There are specific phorbol ester receptors on cardiac myocytes which may be identical with the calcium/phospholipid-dependent protein kinase (protein kinase C). Incubation of enzymatically dissociated rat cardiac myocytes with biologically active phorbol esters (such as 40phorbol-12,13-dibutyrate and 12-O-tetradecanoyl phorbol13-acetate) leads to a timeand concentration-dependent loss of jS-adr...

During the progression of Mycoplasma hominis cultures from the early logarithmic phase to the stationary phase of growth, the total phospholipid content of the cell membranes decreased. Measurement of the amount of the various phospholipids during the growth cycle showed that a decrease in the phosphatidylglycerol (PG) content, accompanied by an increase in the phosphatidic acid content, occurr...
