Background: The application of nano-particles (NPs) in various industries is growing. Since their toxicity is not clearly understood, they can cause adverse effects on the environment. The aim of this study was to evaluate the histopathological effects of iron oxide nano-particles on the small intestine of common carp, Cyprinus carpio. Methods: Four experimental treatments were designed (15 ...
A type of iron-bound protein was isolated from Clostridium botulinum by a modification of the method used for isolating ferredoxin from C. pasteurianum. This method involved acetone and diethylaminoethyl cellulose treatments followed by ammonium sulfate fractionation. The protein exhibited maximal absorption in the ultraviolet region near 260 mmu. Portions of the isolated iron protein were sepa...
Anaerobic digestion requires a balanced availability of micro-nutrients with ideal growth conditions to reach optimal organic degradation and biogas production. Iron is the most abundant of the essential metals in an anaerobic digester and its mobility has a strong impact on microorganisms through its own bioavailability, but also through its influence on the bioavailability of other metals. Mo...
The present study aimed to investigate the effects of root surface iron plaque on the uptake kinetics of arsenite and arsenate by excised roots of rice (Oryza sativa) seedlings. The results demonstrated that the presence of iron plaque enhanced arsenite and decreased arsenate uptake. Arsenite and arsenate uptake kinetics were adequately fitted by the Michaelis-Menten function in the absence of ...
holy basil (ocimum sanctum) is one of the important medicinal plant belongs to lamiaceae family. in order to evaluate the effect of foliar application of iron on iron and chlorophyll contents and photosynthetic parameters of holy basil, an experiment was conducted at research farm of department of horticultural science, shahid chamran university of ahvaz based on randomized complete block desig...
A new phosphate-binding agent which does not cause any severe side effects in vivo was developed by modifying a crosslinked dextran with polynuclear iron(III)oxide-hydroxide. Its particle size ranges from 150 to 300 microns, and the iron content was about 18% by dry weight. The oxidation state of iron was characterized by ESCA and Mössbauer spectroscopy. The maximum phosphate binding capacity o...
Sucroferric oxyhydroxide (VELPHORO) is a polynuclear iron-based phosphate binder recently approved for the treatment of hyperphosphataemia in patients with chronic kidney disease (CKD). As a number of the available phosphate binders do not provide the optimal combination of good efficacy, adequate tolerability and low pill burden, sucroferric oxyhydroxide constitutes a promising alternative. Am...
Application of humic acid as an organic acid derived from humus and other natural resources along with iron could be beneficial to overcoming, at least in part, the nutrients deficiencies in the grapes. In order to evaluate the effects of humic acid and iron on fruit yield and concentration of nutrient elements in the leaf of grape, a factorial experiment based on a randomized complete block de...
In order to use the “Trinidad de Guedes" phosphorite (TGP) as a supplement of calcium and phosphorus in animals, its concentrations of heavy metals were determined and their deposition was analyzed in broilers. Toxic elements were determined using atomic absorption spectrophotometry. The mean levels of heavy metals found in TGP were 82.5 mg/kg lead (Pb), 7.2 mg/kg cadmium (Cd), 1056.9 mg/kg man...
