To elucidate effect of chemical reagents addition on growth of aquatic plants in restoration of aquatic ecosystem, Spirodela polyrrhiza (L.) Schleid was used to evaluate its physiological responses to excess iron (Fe(3+)) and copper (Cu(2+)) in the study. Results showed that accumulation of iron and copper both reached maximum at 100 mg L(-1) iron or copper after 24 h short-term stress, but exc...

Electronic states of iron ion complexes in human blood from patients with melanoma have been investigated by electron paramagnetic resonance (EPR). The measurements were performed at liquid nitrogen temperature (77 K) on an X-band EPR spectrometer. Numerous types of iron paramagnetic centers have been identified. In several kinds of protein complexes exemplified by methemoglobin, transferrin or...

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 ...

BACKGROUND: Management of nutrients, especially nitrogen, in order to have economic production, maintain sustainable agriculture and provide food security, is considered to have an important priority. OBJECTIVES: Current study was conducted to evaluate effect of different level of nitrogen fertilizer and vermicompost on quantitative and qualitative traits of w...

Background: The nature of inheritance and type gene action governing nutritional traits are complex, hence a better understanding the factors that contribute to overall grain quality rice will lay foundation for developing new breeding selection strategies combining high with yield. present investigation was carried out understand yield in rice. Methods: Crosses were effected ten parents dialle...

The hawthorn fruits have been used as food and medicine for centuries. In the present study, pulp and seed extract of Crataegus elbursensis Rech. F. fruits belonging to the family Rosaceae and native of northern part of Iran were evaluated for the polyphenol contents, antiradical, antioxidant, and antibacterial activities. The total phenolic, flavonoid, and anthocyanin contents of methanolic pu...

The manganese concentration levels in three recombinant ferritins were greater Ferritin releases iron to cells for bio-synthetic proteins or enzymes that utilize iron(5, 6). Ferritin can use a threephase tunnel (X, Y, Z) on the protein shell as a affinity column (GE healthcare) according to the manufacturer's instruction. Heme iron polypeptide for the treatment of iron deficiency anemia in non-...

abstractbackground and objectives the oilseeds after cereal, the world's second largest food supply make up. environmental stress has always been one of the most important factors reducing crop yield and production are gone and counter or reduce the effects of stress as a useful strategy to increase the quality and quantity of the products has been considered. flooding conditions are said ...

studies on the genes contributing to the seed filling in chickpea and its protein content might be valuable in engineering plants with seeds of a higher nutritional value. a gene of interest is phosphoenolpyruvate carboxykinase (pepck), encoding a protein with a substantial role in the gluconeogenesis pathway. in the present study, the protein content (percentage) was measured in a number of cu...
