Background: Artemia urmiana are small crustaceans that because of its non-selective filter feeder pattern potentially may absorb high level of heavy metals through their living environment. In this study, the effects of different levels of cadmium and copper on survival, catalase activity and metals bioconcentration rates in A. urmiana nauplii have been investigated. Methods: The research wa...

the demand for low fat snacks is increasing. there are different methods to produce low fat fried products. one of these methods is coating. in this study effect of carrageenan, oil temperature and frying time, on oil uptake of fried products (chips and strips) has been evaluated. samples were deep fried in frying oil (palm olein) at 160, 175 and 190 ºc. in order to evaluate the effect of fryin...

fertilizers usually enhance potassium (k) content and other naturally occurring radioactive materials in agricultural fields that eventually enter the human food chain through plants. in this study, pot-grown rice plants planted in soil that is relatively high in natural radioactive content was used to estimate the individual influence of fertilizer applications on the uptake of 226ra, 232th, a...

Positron emission tomography (PET) imaging using 2-deoxy-2-[F-18]fluoro-D-glucose (FDG) has proven valuable in the diagnosis, staging and restaging for many cancers. However, its application for liver cancer has remained limited owing in part to the relatively high background uptake of the tracer in the liver plus the significant variability of the tumor specific uptake in liver cancer among pa...

The interaction between sodium and calcium, magnesium and calcium and the combined effect of sodium, magnesium and calcium was observed on the growth and ion uptake of Hippophae rhamnoides L. The results demonstrated that an addition of sodium with calcium, (set a, Na 2.5 + Ca 5 mM) showed prominent increase in fresh weight of roots and shoots. The dry weight (average) of roots decreased an...

fifteen kinds of local wetland plants in taihu lake region of china were investigated on their respective growth conditions, biomass allocations and nutrient uptake capacities. the test plants were cultured in 3 l nutrient solutions for 28 days with nh4 +-n, no3 --n and p concentrations of 38.5, 132.8 and 10 mg/l, respectively. mean species total biomass ranged from 1.2-21.6 g/plant with a...

nitrate and ammonium forms of nitrogen are being applied to improve plant growth and uptake of other nutrients. given that the effect of application of different nitrate to ammonium ratios accompanied by other fertilizers (i.e. fe, mn and zn) has not been studied on wheat growth as well as uptake of fe, mn and zn, three glasshouse pot studies were conducted with factorial arrangement of treatme...
