Analysis of the volatile components of heated esterified propoxylated glycerols
… esterified propoxylated glycerols (EPGs), EPG-08 oleate and EPG-08 linoleate. Approximately 4 L of each oil sample (triolein, trilinolein, EPG-08 oleate and EPG-08 linoleate) with and without added antioxidants were separately heated in a deep fat fryer at $\rm 190\sp\circ C$ for 12 h each day …

Investigations on the Behaviour and Properties of Different Types of Unilamellar Vesicles
… of vesicles in the case of single chained oleate surfactant and mixed vesicles of catanionic aggregation of oleate with some cationic surfactants, with a focus on the phase behaviour. Aqueous solution of 200 mM Na-oleate was isotropic micellar and was low viscous. Addition of octanol and …

The analysis of the non-volatile components of heated fatty acid esterified propoxylated glycerols
"EPG-08 oleate, triolein, EPG-08 linoleate and trilinolein, with and without antioxidants, were heated separately in a deep-fat-fryer at 190$\sp\circ$C for 12 hr/day until the polymer content was $\ge$ 20%. EPG-08 oleate (modified low-to-noncaloric triacylglycerol (TAG)) reached 20% polymer …

Investigation of Protein-Fatty Acid Interactions in Zein Films
Results suggested that formation of zein-oleate films may involve an initial hydrophilic adsorption of oleic acid onto zein followed by development of hydrophobic associations leading to film structural organization. Results from this study provide new insight on the mechanism for zein-oleic acid …

Structure and Function of HAMLET: Epitopes, Membrane Interactions and Molecular Recognition
… triggered rapid ion fluxes in the presence of oleate, were internalized by tumor cells and caused rapid changes in cell morphology and tumor cell death with comparable efficiency as HAMLET. These findings demonstrate that the gain of tumoricidal activity in HAMLET is due to a loss of tertiary …

Effects of long-chain surfactants, short-chain alcohols and hydrolyzable cations on the Hydrophobic and Hydration Forces
… (TFE), pyridine, CaCl2, MgCl2 and sodium oleate were studied. A Mark IV SFA was used to conduct force measurements between mica surfaces in aqueous solutions of DOAHCl, which is a secondary amine. At 7x10-6M DOAHCl, the mica surfaces were rendered electrically neutral, and net attractive …

The mechanism of HAMLET-induced cell death - cellular signalling, oncogenes and clinical perspectives
… in tumour cell death. Paper III identifies oleate as the functional ligand in HAMLET formation and shows that oleate actively contributes to the induction of the cellular response to HAMLET. Both protein and lipid are needed for HAMLET’s tumoricidal effect, however. Finally, in paper IV we …
