Background In this study, a two-step processing method (hydrothermal liquefaction followed by catalytic upgrading) was used to produce upgraded bio-oil. A comprehensive screening analysis of algal species, including four microalgae and four macroalgae, was conducted to bridge the gap between previous accounts of microalgae and macroalgae hydrothermal liquefaction and the upgrading process of th...

three hundred twin births from a hospital in tehran, iran have been analyzed for seasonal variation at birth and physical measurements. the results show that the highest twinning rates for mm (5.61), ff (7.73) and mf (5.36) were seen in april, january and september, respectively. the four physical measurements at birth showed non-significant differences among the male and female twins, but mm a...

a experiment was lay out in order to evaluate the effects  of different biofertilizers on yield and yield components of maize at the lorestan provience, iran. the experiment was a factorial design with three replications. treatments were three nitrogen biofrtilizers (nitrokara (n1), o4 (n2), o6 (n3) and control (n4)) and three phosphate biofrtilizers (phosphate barvar2 (p1), biozarr (p2), mc1+p...

studies show that any complications including hemorrhage, lack of blood supply, lack of oxygen supply, and death of cells in a tissue, will have a clear effect on electrical properties of that tissue. thus, by measuring impedance of a set of tissues, potential problems of the damaged tissue may be found. since electrical impedance is closely related to the measuring frequency, obviously, every ...

Molecular distillation technology has been adopted to obtain a bio-oil fraction rich in carboxylic acids and ketones. This unique bio-oil fraction was then upgraded with a La-promoted solid acid catalyst. Three washing pretreatments were used to prepare catalysts A, B, and C, with the intention of reducing the amounts of residual sulfuric acid. Model reactions were used to estimate their cataly...

Administration of bio-tea (1.71 ml/kg) to normal albino mice caused hypoglycemia after 30 min which reached to maximum after 2 hr with a significant decrease in blood sugar level (BSL) and became normal beyond 8 hr. In alloxan-induced diabetic albino mice, repeated treatments of bio-tea for 3 days (five doses) brought about a significant fall in mean BSL. Continuous decrease in BSL was observed...

Palladized biomass of Desulfovibrio vulgaris (Bio-Pd(0)) reduced Cr(VI) to Cr(III) at an initial rate four-fold higher than chemically-prepared Pd(0) metal. Optimal Cr(VI) reduction by suspended BioPd(0) occurred at pH 3, whereas pH did not affect the rate of Cr(VI) reduction by Bio-Pd(0) immobilized in agar beads. The rate of Cr(VI) reduction was concentration-dependent below 300 μmol dm−3, an...

Endothelial cell (EC) dedifferentiation in relation to neovascularization is a poorly understood process. In this report, we addressed the role of Wnt signaling in the mechanisms of neovascularization in adult tissues. Here, we show that a low-dose of 6-bromoindirubin-3'-oxime (BIO), a competitive inhibitor of glycogen synthase kinase-3β, induced the stabilization of β-catenin and its subsequen...

introduction: birth weight is one of the important sanitary indices in evaluating the prenatal care all over the world. the purpose of this research was to determine the relationship between the bio-environmental characteristics of mothers with infant’s birth weight. materials and methods: in corrolation study, first, all newborn babies in hospitals and maternity centers khuzestan between farwa...

We demonstrated that reductive degradation of hexahydro-1,3,5-trinitro-1,3,5-triazine (Royal Demolition Explosive, RDX) can be enhanced by bio-reduced iron-bearing soil minerals (IBSMs) using Shewanella putrefaciens CN32 (CN32). The highest rate constant was obtained by bio-reduced lepidocrocite (0.1811 h-1) during RDX degradation, followed by magnetite (0.1700 h-1), green rust (0.0757 h-1), he...
