“An increased use of bio fuels would contribute to sustainable development by reducing greenhouse-gas emissions and the use of non-renewable resources. Lignocellulosic biomass, including agricultural AZD6094 inhibitor and forestry residues instead of traditional feedstock (starch crops), could prove to be an ideally inexpensive and abundantly available source of sugar for fermentation into transportation fuels. Cellulose, accessible surface area, protection by lignin, and sheathing by hemicelluloses all contribute to the resistance of cellulose in biomass to hydrolysis for the conversion to fuels. Our research had as objective the reduction of lignin by supercritical fluid extraction process by choosing optimal 432 Parameters of extractant, extraction time, pressure and temperature adapted on plant material used. Tests of lignin extraction with supercritical CO2 in laboratory facilities
were performed on cobs and corn stalks. Parameters were followed biomass size ( smaller than 2.35 mm, 2.35 to 3.5 mm), the influence of the type of solvent (methanol and butanol) and co solvent concentration (50-100%). The best results were obtained in extraction with methanol / water 50% v / v. Research is part see more of the ERA IB 6001, international project.”
“The present study was designed to determine ANG peptide content [ANG I, ANG II, ANG( 1-7)], ACE2 mRNA, and the immunocytochemical
distribution of ANG-(1-7) and ACE2 in the uteroembryonic unit during early and late gestation in Sprague-Dawley rats and in a rat model of pregnancy-induced hypertension, the reduced uterine perfusion pressure (RUPP) model. At early pregnancy ANG-(1-7) and ACE2 staining were localized in the primary and secondary decidual zone and luminal and glandular epithelial cells. During late gestation, ANG-(1-7) and ACE2 staining was visualized in the labyrinth placenta and amniotic and yolk sac epithelium. Uterine ANG https://www.selleckchem.com/products/srt2104-gsk2245840.html II concentration at early pregnancy was significantly decreased by 21-55% in the implantation and interimplantation sites compared with virgin rats, whereas ANG-(1-7) levels were maintained at prepregnancy levels. At late gestation, uterine concentrations of ANG I and ANG II were significantly increased (30% and 25%, respectively). In RUPP animals, ANG-(1-7) concentration is significantly reduced in the uterus (181 +/- 16 vs. 372 +/- 74 fmol/g of tissue) and placenta (143 +/- 26 vs. 197 +/- 20 fmol/g of tissue). ACE2 mRNA increased in the uterus of early pregnant compared with virgin rats, yet within the implantation site it was downregulated. At late pregnancy, ACE2 mRNA is elevated by 58% in the uterus and decreased by 59% in RUPP animals.
