This research was conducted to evaluate effect of potassium and iron fertilizers on agro-physiological traits affected different irrigation regime of corn in Shahryar (Tehran province, central of Iran) via a split-split plots arrangement based on randomized complete blocks design with three replications during 2015. The main plot included different irrigation regime (Normal irrigation and stop ...

In June 2007 sediment cores were collected in Alaminos Canyon, Gulf of Mexico across a series of seismic data profiles indicating rapid transitions between the presence of methane hydrates and vertical gas flux. Vertical profiles of dissolved sulfate, chloride, calcium, magnesium, and dissolved inorganic carbon (DIC) concentrations in porewaters, headspace methane, and solid phase carbonate con...

Methylmercury has been thought to be produced predominantly by sulfate-reducing bacteria in anoxic sediments. Here we show that in circumneutral pH sediments (Clear Lake, CA) application of a specific inhibitor of sulfate-reducing bacteria at appropriate concentrations typically inhibited less than one-half of all anaerobic methylation of added divalent mercury. This suggests that one or more a...

Laver belongs to the genius of Porphyra and is the most valuable seaweed in the aqua-culture industry. It contains higher iron than many other plant foods. The bioavailability of iron from laver was evaluated in a rat hemoglobin regeneration assay. Reagent-grade ferrous sulfate was used as the reference standard, and the relative biological value (RBV) for laver was expressed as a percentage of...

We assessed the clinical response and side effects of Ferrous sulfate (FS) and Iron polymaltose complex (IPC) in 118 children with Iron deficiency anemia (IDA). Subjects were randomized to receive therapy with either oral IPC (Group A, n=59) or oral FS (Group B, n=59); all were given elemental iron in three divided doses of 6 mg/kg/day. One hundred and six children could be followed up; 53 in e...

The lignocellulosic wastes produced in food industries are suitable raw materials for the production of biological products. In this study, the solid state fermentation of Aspergillus flavus on lignocellulosic wastes was evaluated for microbial protein production. The fraction of the full factorial method was applied for experiment design and process optimization. The results analysis was perfo...

The concentration of the iron-chelating agent, desferrioxamine (Desferal), that just inhibits iron entry into HeLa cells is also the concentration that inhibits DNA synthesis. As a first step in clarification of the mechanism whereby iron may partake in DNA synthesis, we have partially characterized several of the intracellular iron-binding sites. Most cytoplasmic iron appears to be bound to a ...
