zno nanoparticles were synthesized by a microwave-assisted chemical method. zno nanostructures were synthesized via a fast reaction between zinc acetate and ammonia at presence citric acid and other effective agents in chemical procedure. nanostructures were characterized by x-ray diffraction , scanning electron microscopy. seed yield and seed quality of safflower grown under drought stress. th...

acute toxicity test on common carp weighing 18 grams and length 12 cm was performed. with concentrations of 0, 2, 5, 10, 20, 40, 60, 80, 100, 200, 400, 600, 800 and 1000 ppm measured at 0, 24, 48 and 96 hours were considered for commercial diesel . processing data using spss software and statistical analysis probit analysis was performed with a confidence level of 95%. the common carp no deaths...

BACKGROUND Hepatitis B is a serious global public health concern. Though a safe and efficacious recombinant vaccine is available, its use in several resource-poor countries is limited by cost. We have investigated the production of Hepatitis B virus surface antigen (HBsAg) using the yeast Pichia pastoris GS115 by inserting the HBsAg gene into the alcohol oxidase 1 locus. RESULTS Large-scale p...

A 36-year-old Chilean woman with depressive disorder was prescribed treatment with lamotrigine starting at a dosage of 25 mg/d and increasing 25 mg per week. When she reached 75 mg/d at the third week, she presented with an acute abdominal skin eruption. She was evaluated in an emergency department and received 1 dose of sodium phosphate betamethasone and dexchlorpheniramine maleate, 5.3 mg, in...

A whole-cell biocatalyst with the ability to induce synergistic and sequential cellulose-degradation reaction was constructed through codisplay of three types of cellulolytic enzyme on the cell surface of the yeast Saccharomyces cerevisiae. When a cell surface display system based on alpha-agglutinin was used, Trichoderma reesei endoglucanase II and cellobiohydrolase II and Aspergillus aculeatu...

in order to evaluate the effect of zeolite application and selenium spraying on some physiological traits and grain yield in medicinal pumpkin (cucurbita pepo l.) under different moisture regimes, a study was conducted in a factorial experiment based on randomized complete block design with three replications during 2010 in takestan at gazvin province, iran. the three levels of irrigation facto...

The Richmond Mine of the Iron Mountain copper deposit contains some of the most acid mine waters ever reported. Values of pH have been measured as low as -3.6, combined metal concentrations as high as 200 g/liter, and sulfate concentrations as high as 760 g/liter. Copious quantities of soluble metal sulfate salts such as melanterite, chalcanthite, coquimbite, rhomboclase, voltaite, copiapite, a...

Background: Sedentary lifestyle and lack of exercise cause cardiovascular diseases metabolic syndrome. Decreased movement in recent decades has caused diseases. Methods: In this research, 35 male Wistar rats weighing 220 ± 20 g were divided into 5 groups (seven each group) by a simple random method. The first second experimental given 100 grams per liter fructose with water for 6 weeks, the thi...
