in order to investigation the effect of different fertilization treatments on nutrient and essential oil contents in dragonhead drug (dracocephalum moldavica l.), an experiment was conducted in the station of agricultural research in urmia on 2008. treatments (nitroxin, barvar phosphate biofertilizer, biosulfur, nitroxin+ barvar phosphate biofertilizer, barvar phosphate biofertilizer + biosulfu...

The major purpose of the present investigation was to study the effects of different concentrations of residual chlorine on serum iron related parameters in rats. Feeding male rats with water containing 80 ppm of residual chlorine daily for 5 days reduced serum levels of ceruloplasmin, copper, iron and hemoglobin by approximately 27%,23%,6% and 4%, respectively. Higher reductions in serum ...

Effect of nano composite films to prolong the shelf life of Iranian beluga caviar was investigated at different concentrations of silver nanoparticles. In this study 38 caviar packs each containing 5 g of caviar were divided into 6 treatments with 3 replicates. The concentrations of 1000, 2000, 3000, 4000, 5000 and 6000 ppm of nanoparticles as well as a nano free pack as control were used. The ...

This study aimed to manipulate the texture and elemental composition of the novel sheaths produced by the iron-oxidizing bacterium Leptothrix in culture by altering components of the medium. When previously isolated strain OUMS1 was cultured in media (pH 7.0 throughout incubation) containing various levels of Si on a rotary shaker at 20 °C and 70 rpm for 14 days, the strain was able to reproduc...

Arbuscular mycorrhizal fungi (AMF) is a fungus that has symbiotic impact on the plant at root system level. The research objective was to evaluate growth of Indigofera zollingeriana produced from inoculation AMF under different fortification and fertigation techniques field scale. A completely randomized design with six treatments five replication were applied for study. were: FD1000, FD2000, F...

BACKGROUND Iron metabolism during pregnancy maintains fetal iron levels at the expense of the mother. The mechanism behind this regulation is still not clear despite recent advances. Here we examine the role of maternal and fetal Hfe, its downstream signaling molecule, hepcidin and dietary iron in the regulation of placental iron transfer. DESIGN AND METHODS Hfe wild-type, knockout and hetero...

zafarabad iron deposit is located northwest of divandareh, in the northern margin of sanandaj-sirjan plutonic-metamorphic zone. the deposit is in lentoid to tubular shape, within a shear zone and occrrued in host rocks of calc-schist and limestone. magnetite with massive, cataclastic and replacement textures are the main phases, while pyrite and other sulfide minerals are found. major and trace...

Octylphenol (OP) is a commercial intermediate used primarily for the production of octylphenol polyethoxylate surfactants. To determine potential reproductive toxicity of OP, a two-generation reproduction study was conducted according to U.S. EPA OPPTS Guideline 870.3800 (draft 1996). Additional measurements were made on retained F2 offspring. OP was administered ad libitum to five groups of ra...
