influence of arbuscular mycorrhizal fungi (amf) (glomus etunicatum, g. intraradices and glomus versiforme) and external phosphorus supplement (8 and 35 mg p kg-1 soil) on leaf p, zn, cu and fe nutrition of 4-month-old tea(camellia sinensis) was studied in an glass house pot experiment. the highest leaf p concentration (up to 59.43% increase) was found in g. versiforme inoculated seedlings gro...

Root-zone temperatures (RZT) in relation to Cu and Zn uptake and tissue accumulation, and to total biomass, in potato plants (Solanum tuberosum L. var. Spunta) were studied. Using five different plastic mulches (no cover, transparent polyethylene, white polyethylene, coextruded white-black polyethylene, and black polyethylene) resulted in significantly different RZT (16, 20, 23, 27, and 30 degr...

We developed a new method of fabricating a divalent copper ion (Cu(2+)) modified DNA thin film on a glass substrate and studied its magnetic properties. We evaluated the coercive field (Hc), remanent magnetization (Mr), susceptibility (χ), and thermal variation of magnetization with varying Cu(2+) concentrations [Cu(2+)] resulting in DNA thin films. Although thickness of the two dimensional DNA...

objective: the appropriate choice of a contraceptive method has been a major issue in reproductive health research. cu t intrauterine device (cu t iud) has been introduced as one of the most effective contraceptive methods in the world, however, the relationship between prior use of cu t iud and secondary infertility has not been evaluated in iran. to examine the association of cu t-380a iud an...

the feasibility of kaolinite used as a low-cost adsorbent for the removal of pb(ii), zn(ii) and cu(ii) from aqueous solutions was investigated. during the removal process, batch technique was used, and the effects of heavy metal concentration and contact time on adsorption efficiency at ph of 4.5, under a constant temperature of 20?1 ?c were studied. the experimental results were analyzed using...

BACKGROUND The altered levels of some essential trace elements and antioxidant minerals have been observed in diabetic patients. OBJECTIVES The aim of the present study was to compare the concentrations of essential trace elements, copper (Cu), zinc (Zn), and iron (Fe) in the serum of patients who have type 2 diabetes mellitus (T2DM) with those of their non-diabetic first-degree relatives (FD...

Soil aggregates were prepared from a bulk soil collected from paddy soil in the Taihu Lake region and aluminum (Al) dissolution, solution pH changes during copper (Cu(2+)) sorption were investigated with static sorption and magnetic stirring. Kinetics of Cu(2+) sorption and Al dissolution were also studied by magnetic stirring method. No Al dissolution was observed until Cu(2+) sorption was gre...

Results from experiments investigating Cu metabolism in ruminants indicate that Cu is involved in lipid metabolism. Copper supplementation ranging from 10 to 40 mg of Cu/kg of DM to high-concentrate finishing diets decreased subcutaneous adipose tissue deposition and decreased cholesterol concentrations but increased unsaturated fatty acid composition of LM. Serum norepinephrine tended to be gr...

In the present study, the growth of Chrysanthemum coronarium L. and Sorghum sudanense L. and their copper accumulation were studied using hydroponic experiments. Results showed that the root elongation, dry biomass yield, and chlorophyll content in both plant species decreased significantly with the increasing level of Cu in solution. The concentrations of Cu in the two plants increased greatly...

In a study of diet and early breast cancer, blood plasma copper has been analyzed by Proton Induced X-ray Emission analysis as both total copper (P-Cu) and that ultrafiltrable from plasma (P-edu-Cu) through membranes with a cut-off at molecular mass 10,000 after equilibration with disodium ethylene diamine tetraacetic acid (EDTA) at 4 degrees C. Ceruloplasmin (P-cer) was also measured using nep...
