In this study, the YBa2Cu3O6+x samples at temperatures 200 and 300°C, as the value of x ( the oxygen content in 0the basal plane)  increased under nearly thermodynamical equilibrium condition, the structure changed from the well- known tetragonal (T) to a mixed-phase (T+OII) region (orthorhombicII phase is a superstructure). This mixed-phase region suggests a first order T/OII phase transition ...

background research in the area of herbal psychopharmacology has clearly improved in recent decades. self-administration of herbal medicines has been the most popular therapeutic alternative to standard medicine. objectives since the extract of echium amoenum exhibits an anxiolytic effect, the aim of this study is to evaluate the anxiolytic and hypnotic effects in mice of the aqueous and ethano...

in present paper, dynamic behavior and control of a fluidized bed reactor for polyethylene production has been considered. a double active sites model for ziegler-natta catalysts is used for simulation of polymerization reaction. hydrodynamic behavior of the bed is modeled using a two phase model including bubble and emulsion phases in which bubble phase has plug flow pattern with differentiall...

How do humans and other animals accomplish coordinated movements? How are novel combinations of limb joints rapidly assembled into new behavioral units that move together in in-phase or anti-phase movement patterns during complex movement tasks? A neural central pattern generator (CPG) model simulates data from human bimanual coordination tasks. As in the data, anti-phase oscillations at low fr...

cyclizine (1-benzhydryl-4-methyl-piperazine, cas 82-92-8, cyc, i), a piperazine derivative, belongs to h1 antihistamine group of drugs that shows such pharmacological properties as anti-inflammatory, anti-allergic and anti-platelet effects, similar to other h1-receptor antagonists. in this study, two new tolyl and cumene derivatives of i (1-ethyl-4-[(p-isopropylphenyl) (p-tolyl) methyl]-piperaz...

Background: Growth factors play a major part in wound healing in many tissues including the periodontium. Transforming growth factor-β1 (TGF-β1) is one of these factors present in the gingival crevicular fluid. In addition, it is considered as one of the most important anti-inflammatory cytokines. Interleukin-1β is a proinflammatory cytokine that presents itself in gingival inflammation and the...

Objective: This study was aimed to examine the antinociceptive and anti-inflammatory effects of Urtica dioica leaf extract in animal models. Materials and Methods: Hydroalcoholic extract of the plant leaves was prepared by percolation method. Male Swiss mice (25-35 g) and male Wistar rats (180-200 g) were randomly distributed in control, standard drug, and three experimental groups (n=6 in each...

Modified cellulose acetate (CA) membranes were prepared by dissolving the polymers in a mixture of acetone (AC) and N, N dimethylacetamide (DMAc) (70:30) solvent and deionized (DI) water was used in the coagulation bath. The introduction of polyethylene glycol (PEG) additive and TiO2 nanoparticles (NPs) into the casting solution has changed the structures of the resulting membranes during the p...

Background: Plasma medicine is an innovative and emerging field used in a broad range of medical conditions. Objective: The present study focused on consumption, documentation pattern and traceability of plasma-derived medicines in a teaching and referral hospital. Method: A two-step study was conducted from October to December 2015. During the first phase, the patient records receiving plasm...
