TL;DR: The n-3 to n-6 fatty acid ratio determined the immunoregulatory potential of intravenous fat emulsions in vivo and both n- 3 and n- 6 fatty acids were immunosuppressive when applied as the main polyunsaturated fatty acid sources.
Abstract: BACKGROUND The immune system is reported to be influenced by polyunsaturated fatty acids. Therefore, immunoregulation caused by intravenous fat emulsions with different n-3 to n-6 fatty acid ratios was studied in an in vivo model. METHODS Experimental rat heart allotransplantation served as a defined immunologic challenge. Twenty percent emulsions of safflower oil (n-3 to n-6 = 1:370), fish oil (n-3 to n-6 = 7.6:1), and soybean oil (n-3 to n-6 = 1:6.5), and a 1:1 mixture of safflower oil and fish oil (n-3 to n-6 = 1:2.1) were continuously infused (9 g of fat per kg of body weight per day) after transplantation until complete rejection. The prolongation of graft survival, an accepted parameter of immunosuppression, was assessed. Beyond that, cytokine release by mitogen-stimulated peripheral-blood mononuclear cells (PBMCs) from animals exsanguinated on day 4 after transplantation was evaluated. RESULTS The mean rejection time was 7.8 days in the sham-infused saline control group and 6.7 days in the safflower- and fish-oil-mixture group (oil control group). Continuous infusion of soybean oil prolonged the graft survival time to 10.4 days, fish oil to 12.3 days, and safflower oil to 13.3 days. PBMC alpha-tumor necrosis factor release was significantly reduced in the fish-oil group (51.9 +/- 13.0 pg/10(6) PBMCs vs 70.8 +/- 10.9 pg/10(6) PBMCs [controls], p < .004). Interleukin-6 release was diminished in both the fish-oil group (22.2 +/- 13.6 pg/10(6) PBMCs vs 40.7 +/- 8.3 pg/10(6) PBMCs [controls], p < .002) and the safflower-oil group (28.4 +/- 6.9 pg/10(6) PBMCs, p < .002). CONCLUSIONS The n-3 to n-6 fatty acid ratio determined the immunoregulatory potential of intravenous fat emulsions in vivo. Both n-3 and n-6 fatty acids were immunosuppressive when applied as the main polyunsaturated fatty acid sources. PBMC cytokine release was significantly reduced in these groups. The more balanced the n-3 to n-6 ratios, the less immunosuppressive the fat emulsion. There was no immunosuppressive effect at an n-3 to n-6 ratio of 1:2.1.

TL;DR: In this article, the use of ozonized vegetable oils as pour point depressant for neat biodiesel was evaluated, and it was shown that they are effective in reducing the pour point of biodiesel prepared from sunflower oil, soybean oil, and rapeseed oil.

TL;DR: An evaluation of thiobarbituric acid (TBA) as an agent for the measurement of fat oxidation was made by the application of several empirical procedures to animal and vegetable fats as mentioned in this paper.
Abstract: An evaluation of thiobarbituric acid (TBA) as an agent for the measurement of fat oxidation was made by the application of several empirical procedures to animal and vegetable fats. An extraction procedure was used for removing the products of oxidation. The reaction with TBA was conducted in a boiling water bath to produce a red color, which was then estimated spectrophotometrically. Fats stored at −20, 0, 72, and 100°F. (−29, −18, 22, and 38°C.) and fats oxidized by the active oxygen method (A.O.M.) and by ultraviolet irradiation were examined. It was found that the TBA test might be of value in following the course of oxidation of cottonseed oil and soybean oil in the A.O.M. apparatus. Higher TBA values were obtained for soybean oil than cottonseed oil at comparable peroxide values. This is of interest because of the greater tendency of soybean oil to develop oxidized flavors. The volatile reaction products of oxidation were collected in toluene, and a comparison of the TBA values at comparable peroxide values of lard, cottonseed and soybean oils showed that the soybean oil volatiles developed the greatest intensity of color.

TL;DR: The transesterification procedure of triacylglycerides from soybean oil to give biodiesel was adapted to semi-micro laboratory scale as an additional experimental technique of nucleophilic acyl substitution for undergraduate courses in Chemistry and related areas as discussed by the authors.
Abstract: The transesterification procedure of triacylglycerides from soybean oil (in natura and waste oil) to give biodiesel was adapted to semi-micro laboratory scale as an additional experimental technique of nucleophilic acyl substitution for undergraduate courses in Chemistry and related areas.
