'' Erythrocytes from 22 normotensive pregnant women and 15 Multivariate analysis and logistic regression were applied to differentiate between the 2 groups of patients, and used to develop a diagnostic model based on the concentrations of the constituents
Significantly higher concentrations of alanine (P < 01), glycine (P = 25), and ergothioneine (P = 49) were found in erythrocytes from preeclamptic patients. Discriminant analysis and regression of NMR data permitted 100% accurate diagnosis of the health status of new patients. Chemically related imidazole-based molecules, histidine and ergothioneine, are important in the classification process and the etiology of preeclampsia (PE).[The oil, fatty acid and squalene content of varieties of raw and processed Universidad del Valle de Guatemala, Guatemala.The oil, fatty acid and squalene content of varieties of raw and processed grain amaranth. Six amaranth grain varieties were processed to yield a nixtamalized flour, one cooked in water, one expanded, a malted one and a laminate samples after a thermic treatment.
the ordinary squalane cleanser of the raw samples contained from 14% to 15% protein, 5 to 6% ether extract and from 2% to 3% ash on a dry weight basis. The flours from the different processes yield products with a fat content which varied from 6% to 7% for the 6 varieties. The flours coming from dry heat processing contained higher oil levels than those flours coming from wet processes. The oil from only 3 varieties and from 4 processes were analyzed from its fatty acid composition. The oil contained on the average 175% of C16:0, 68% of stearic, olic and linoleic acids, 36% of C18:3, 5% of C20:0 and small amounts of C20:1 and C22:0. The squalene content in the oil of the processed flours varied from 7 to 9 g/100 g for the raw flour, 8 -12 g/100 g for the flour from wet cooking in water, 9 -12g/ 100 g for the flour from the nixtamalization process, 10-12g/ 100 g for the expanded grain flour, 9 to 11 g/100 g for the malted flour and 6-9 g/100 g for the laminated grain flour. The squalene averages per process showed statistical Gas chromatography of squalene, sterols and bile acid methyl esters.
Extraction of squalene as value-added product from the residual biomass of Schizochytrium mangrovei PQ6 during biodiesel producing process.Academy of Science and Technology (VAST), 18 Hoang Quoc Viet Road, Cau Giay, Academy of Science and Technology (VAST), 18 Hoang Quoc Viet Road, Cau Giay, Academy of Science and Technology (VAST), 18 Hoang Quoc Viet Road, Cau Giay, Today microalgae represent a viable alternative source of squalene for commercial application. The species Schizochytrium mangrovei, a heterotrophic microalga, has been widely studied and provides a high amount of squalene, polyunsaturated fatty acids and has good profiles for biodiesel production. ordinary squalane cleanser was aimed at examining the squalene contents in Vietnam's heterotrophic marine microalga S. mangrovei PQ6 biomass and residues of the biodiesel process from this strain. Thin-layer chromatography and high-performance liquid chromatography (HPLC) methods were successfully applied to the determination of squalene in S. mangrovei PQ6.
The squalene content and production of S. mangrovei PQ6 reached 330 ± 02 and 334 ± 03 mg g(-1) of dry cell weight; and 092 g L(-1) and 119 g L(-1) in 30 and 150 L bioreactors, respectively after 96 h of fermentation. In addition, squalene was also detected in spent biomass (approximately 800 ± 03 mg g(-1) of spent biomass) from the S. mangrovei PQ6 biodiesel production process. The structure of squalene in residues of the biodiesel process was confirmed from its nuclear magnetic resonance spectra. The results obtained from our work suggest that there is tremendous potential in the exploitation of squalene as a value-added by-product besides biodiesel from S. mangrovei PQ6 to reduce biodiesel price.
Heterogeneous oxidation of squalene film by ozone under various indoor Abstract The effects of indoor conditions (ozone concentration, temperature, relative humidity (RH), and the presence of NO(x)) on heterogeneous squalene oxidation were studied with Attenuated Total Reflectance-Fourier Transform Infrared spectroscopy. The heterogeneous kinetics of squalene-ozone reaction revealed a pseudo-first-order reaction rate constant of 12 x 10(-5)/s at range of 24-58 +/- 2 degrees C as well as to RH and presence of NO(x). Products, however, were affected by the environmental parameters. As temperature was increased, fewer surface products and more low molecular weight gaseous products were observed. Lower air exchange rates also enhanced gas phase reactions, allowing for formation of secondary gas phase products. As RH increased, there was a shift in product distribution from ketones to aldehydes, and the presence of NO(x) during squalene ozonolysis resulted in the formation of nitrated oxidation products.
