Introduction: Paraoxon (the neurotoxic metabolite of organophosphorus (OP) insecticide, parathion) exerts acute toxicity by inhibition of acetylcholinesterase (AChE), leading to the accumulation of acetylcholine in cholinergic synapses and hence overstimulation of the cholinergic system. Since, reports on changes in the level of γ- amino butyric acid (GABA) during OP-induced convulsion have bee...

Polynuclear aromatic hydrocarbons (PAHs) from sequestered MV Selendang Ayu oil were biologically available in 2008, 3.6 y after it was spilled along Unalaska Island, Alaska. Thermodynamically driven weathering was the most probable mechanism of organism exposure to PAHs. Alkane and PAH composition in oil changed over time as smaller constituents were preferentially lost, indicative of weatherin...

Chronic ingestion of thermoxidized palm oil causes functional derangement of various tissues. This study was therefore carried out to determine the effect of chronic ingestion of thermoxidized and fresh palm oil diets on intestinal fluid and glucose absorption in rats using the everted sac technique. Thirty Wistar rats were divided into three groups of 10 rats per group. The first group was the...

Rainbow trout were exposed for 72 h to [ 14C]anthracene alone and [ I4C]anthracene in an oil shale retort water. Tissue levels of [I4C]anthracene were analyzed at 24, 48 and 72 h to determine non-steady-state bicconcentration factors (BCFs), and uptake and depuration rates were calculated from anthracene disappearance in exposure waters and metabolite appearance in depuration waters. Uptake rat...

We have developed a rapid sampling technique for animal cells in suspension for the purpose of measuring membrane transport in lymphocytes. The method involves rapid centrifugation of cells through a layer of silicone oil into perchloric acid after incubation periods as short as 4 s. Using this method we have described the uptake of thymidine and the uptake and transport systems of adenosine by...

Oil migration from high oil content almond confections into adjacent chocolate causes changes in product quality. The objective of this study was to quantify the oil migration from almond butter and cream products to dark chocolate. Magnetic resonance imaging (MRI) was used to monitor spatial and temporal changes of liquid lipid content. A multi-slice spin echo pulse sequence was used to acquir...

The effect of fish oil and corn oil supplementation on plasma lipids and lipoproteins and on low density lipoprotein (LDL) oxidation was examined in 20 treated hypertensive subjects. The randomized double-blind crossover study consisted of two 6-week interventions with 4 g/day of a highly purified fish oil or corn oil. Fish oil significantly (-24%, P < 0.01) reduced plasma triglyceride, and inc...

Vacuum heat treatment creates an oxygen-free environment, thus positively effects the properties of wood compared to traditional treatment. Crude tall oil is a non-biocidal preservative, composed resin and fatty acids improves some such as water uptake decay resistance. In this study, dissolved in ethanol (10% 20%) for impregnation fir poplar samples according full cell method, followed by subj...

Optimization of the effect pectin and carboxymethyl cellulose gums on oil uptake, textural properties color changes French fries using response surface methodology

In this study, beech wood was treated in hot oil and in hot air to determine the differences in the effects of the two processes on the physical properties of the wood. Heat treatment was conducted at temperatures of 160, 190, and 220 °C for 2 h at atmospheric pressure. After the heat treatment, various properties of the wood, including mass increase in hot oil treatment (wt% gain), mass loss i...
