Wax esters are esters of long-chain fatty acids and long-chain fatty alcohols which are of considerable commercial importance and are produced on a scale of 3 million tons per year. The oil from the jojoba plant (Simmondsia chinensis) is the main biological source of wax esters. Although it has a multitude of potential applications, the use of jojoba oil is restricted, due to its high price. In...

The plasma membrane lipid composition in Li 210 murine leukemia cells was dependent upon the type of fat fed to the host animal. Plasma membranes prepared from cells grown in animals fed 16% sunflower oil contained 39% saturated, 14% monoenoic, and 41% polyenoic fatty acids. In contrast, those from cells grown in mice fed 16% coconut oil contained 39% saturated, 31% monoenoic, and 23% polyenoic...

In this study, catalysts for fatty acid methyl esters (FAME or biodiesel) synthesis with K2CO3 as the active component on an alumina/silica support were synthesized using the sol–gel method, which was followed by drying the “dense” wet gels with supercritical carbon dioxide to obtain the aerogels. The prepared catalysts were characterized by XRD analysis, FTIR spectroscopy and N2 physisorption ...

It has been suggested that the formation of cytoplasmic lipid droplets may produce an artifact and be responsible for the differences in membrane physical properties detected in lipid-modified cells using fluorescence polarization or spin label probes. To investigate this, the electron spin resonance spectra of lipid droplets isolated from the cytoplasm of L1210 leukemia cells were compared wit...

The phenolic antioxidants 2,6-ditertiary-butyl paracresol (DBPC) (also known as butylated hydroxytoluene (BHT)) and 2,6-ditertiary-butyl phenol (DBP) are the two most common oxidation inhibitors added to the electrical insulating (transformer) oil and mineral oil based lubricants. The typical recommended value of DBPC and DBP in fresh electrical insulating oil is approximately 0.3% by weight. T...

Modulation of myelopoiesis by three synthetic muramyl peptides was investigated in vivo. Two adjuvant-active compounds (N-acetylmuramyl dipeptide [MDP] and MDP-butyl-ester) elicited significant responses in DBA/2 mice characterized by a rise in the level of monocyte-macrophage colony-stimulating activity in serum, a proliferation of multipotential stem cells in the bone marrow, and an expansion...

Background: Restricted intakes of saturated and trans-fatty acids and replacement with poly or monounsaturated fatty acids are emphasized in healthy diets. This study evaluates the effects of a six-month consumption of canola oil compared to sunflower oil on lipid profile and anthropometric parameters of people affected by dyslipidemia. Methods: This randomized controlled trial was condu...

A voltammetric electronic tongue to classify five different types of edible oil samples is described in this study. The standard three-electrode configuration composes the sensor array: gold electrode, platinum electrode and saturated calomel electrode. Using cyclic voltammetric measurement, respectively, on five different types of edible oil samples (peanut oil, corn oil, soybean oil, sesame o...

The present study was performed to evaluate the effects of dietary n-3 and n-6 long-chain PUFA (LC-PUFA) on clinical outcome in a porcine model on early aortic vascular prosthetic graft infection (AVPGI). A total of eighty-four pigs were randomised to a 35 d dietary treatment with 10 % (w/w) fish oil (rich in n-3 LC-PUFA), sunflower oil (rich in n-6 LC-PUFA) or animal fat. After 3 weeks of diet...

Artificial diets prepared with wheat germ, soybean protein, dextrosol, potato starch, sucrose, cellulose, soybean or sunflower oil, and vitamin solution for rearing Nezara viridula (L.) and Euschistus heros (Fabricius) were tested under controlled temperature (25 +/- 1 degrees C), RH (60 +/- 10%), and photophase (14h). Three diets were tested and compared with the natural diet privet [soybean a...
