The effects of the amount of dietary fat and saturation together with cholesterol both on hepatic apolipoprotein A-I gene mRNA levels and on plasma levels of this apolipoprotein were studied in male rats. To achieve these goals, seven groups of male Wistar rats were established: control group (n=5) consuming chow diet; cholesterol group (n=4) fed on a chow diet containing 0.1% (w/w) cholesterol...

Biomarker compounds that derived from early living organisms play an important role in oil and gas geochemistry and exploration since they can record the diagenetic evolution of the parent materials of crude oil and reflect the organic geochemical characteristics of crude oil and source rocks. To offer scientific basis for oil exploration and exploitation for study area, gas chromatography-mass...

Gene expression changes that occur during mesocarp development are a major research focus in oil palm research due to the economic importance of this tissue and the relatively rapid increase in lipid content to very high levels at fruit ripeness. Here, we report the development of a transcriptome-based 105,000-probe oil palm mesocarp microarray. The expression of genes involved in fatty acid (F...

In the article by White et al. (1) we find that the authors prematurely linked the condition of a single coral community to the Deepwater Horizon oil spill, without evaluating other plausible explanations, including the presence of natural oil and gas seeps near the coral, and the potential for underwater landslides to carry seep sediments onto the coral. The single coral location in question, ...

Oil compressibility represents a significant character in reservoir simulation, design of surface facilities and the analysis well tests, specifically for systems below bubble point pressure.
 is not directly measured laboratory. It usually gained indirectly from experimental data recorded PVT reports. The relative volume flash test used to calculate oil at pressures above pressure. At poi...

The essential oil of Rosa damascena Mill. is one of the most valuable and important base material in the flavor and fragrance industry. It has also some medicinal properties. The aim of this study was to determine the correlation between anthocyanin and essential oil content of Damask rose petals in 6 important Damask rose growing in some locations of Iran i.e. Meimand, Layzangan, Shiraz Eram B...

BACKGROUND Rapeseed (Brassica napus L.) is an important oil crop in the world, and increasing its oil content is a major breeding goal. The studies on seed structure and characteristics of different oil content rapeseed could help us to understand the biological mechanism of lipid accumulation, and be helpful for rapeseed breeding. METHODOLOGY/PRINCIPAL FINDINGS Here we report on the seed ult...

The volatile shoot oil o f Coleonema album was found to be composed o f monoterpenes, ses­ quiterpenes and phenylpropanoids. Heterotrophic and photomixotrophic callus cultures were established from green parts o f the plant. A photomixotrophic cell line contained a heteroge­ neous population o f plastids and synthesized an essential oil, which differed qualitatively and quantitatively from the ...
