The present study examined the effects of various concentrations (0.1-1.1 ml L-1) of 2-phenoxyethanol, an anesthetic agent, on the stress responses, the hematological parameters and the hepatic enzymes in Siberian sturgeon (Acipenser baerii; Brandt JF, 1869). The results showed that placing Siberian fish in low concentrations of the drug causes deep anesthesia over a longer period in compared ...
Chemical flooding, especially alkaline/surfactant/polymer flooding, is of increasing interest due to the world increasing oil demand. This work shows the aspects of using alkaline/surfactant/polymer as an enhanced oil recovery method in the porous media having a high dead-end pore frequency with various dead-end pore parameters (such as opening, depth, aspect ratio, and orientation). Using glas...
Background: Considerable evidence suggests that oxidative stress affects diabetes mellitus (DM) and contributes to its complications. Vitamin D has been shown to possess antioxidant properties. The aim of this study was to determine the association between serum levels of calcifediol (25-OH-D), an indicator of vitamin D status, and lipid profiles with oxidative stress in patients with type 2 di...
objective: the aim of this study was to estimate the cheminformatics and qualitative structure-activity relationship (qsar) of cinnamaldehyde and eugenol. the effects of cinnamaldehyde and eugenol on the viability, doubling time and adipogenic or osteogenic differentiations of human adipose-derived mesenchymal stem cells (hascs) were also investigated. materials and methods: qsar and toxicity ...
an experiment was conducted to investigate the effect of zinc (zn) supplementation and different concentrations of calcium (ca) and phosphorus (p) in wheat-based diets on the performance, immune responses and bone parameters of broiler chickens. a randomized complete block design with factorial arrangement was used (three concentrations of zn supplementation×two concentrations of dietary ca-p),...
this study was carried out to obtain quantitative relationships between zn in equilibrium solution and that retained by 20 calcareous soils. soils were brought into equilibrium with varying solution concentrations of zn, and the amounts removed from solution were used to check the fit to six adsorption isotherms, namely, freundlich, langmuir, temkin, gunary, two surface langmuir and adjusted fr...
