Previous observations suggested that there may be an association between elevated serum copper (Cu) levels and post-partum depression (PPD). In this study, we examined Zn and Cu levels in women with completed pregnancies who had a history of PPD and compared them to women who did not have depression, and to women who reported having been depressed, but without a history of PPD. Cu levels were s...

Background: Anzali wetland has been subjected to high levels of pollution due to contamination from several industrial sites in addition to agricultural chemicals. Mussels have been widely used for monitoring pollution in aquatic ecosystems, because they, as filter feeders, bioaccumulate pollutants. Therefore we decided to evaluate Anodonta cygnea for its application as a bio-monitor for copp...

A copper/zinc superoxide dismutase (Cu,Zn-SOD) cDNA was cloned from the hepatopancreas of giant freshwater prawn Macrobrachium rosenbergii using reverse transcription-polymerase chain reaction (RT-PCR) by degenerate primers. Both 3'- and 5'-regions were isolated by the rapid amplification of cDNA ends method. Analysis of nucleotide sequence revealed that the Cu,Zn-SOD cDNA clone consists of 845...

Concentrations of particulate phytochelatin, a metal-binding peptide produced by eukaryotic phytoplankton, ranged from 2 to 50 pmol (g Chl a)-’ in samples collected from small harbors in southeastern New England. Although there was no obvious relationship between phytochelatin and total Cu concentrations, phytochelatin varied systematically with free Cu concentrations [Cu*+]. Transects in which...

in the present investigation flocculation of dissolved cu, zn, pb, ni and mn in a series of mixtures with salinities ranging from 1.5 to 9.5% during mixing of talar river water with the caspian sea water was studied. the flocculation trend of zn (87.22%) >mn (45.31%) >pb (39.09%) >cu (36.58%)>ni (12.70%) indicates that cu, zn, pb and mn have non-conservative behavior and ni has relatively conse...

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 (fdr)...

this study was carried out to determination of in vitro binding capacity of organic (wheat and barley) and inorganic (perlite) sources for mn, zn, cu, and fe. for this reason wheat and barley were analyzed chemically for moisture, protein, ash, and ether extract, total carbohydrate, ndf, adf, adl, crude fiber, viscosity, cellulose, and total dietary fiber. the in vitro mineral binding capacity ...

objective(s):to evaluate the effect of trinitroglycerin (tng) as nitric oxide donor agent on serum copper (cu) and zinc (zn) levels and liver enzymes in balb/c mice infected with leishmania major (l. major) mrho/ir/75/er. materials and methods: inbred female mice were divided into three groups: healthy group (uninfected naive mice), control group (infected with l. major), and test group (l. maj...

Three experiments were conducted to evaluate the effects of increasing dietary Cu and Zn on weanling pig performance. Diets were fed in 2 phases: phase 1 from d 0 to 14 postweaning and phase 2 from d 14 to 28 in Exp. 1 and 2 and d 14 to 42 in Exp. 3. The trace mineral premix, included in all diets, provided 165 mg/kg of Zn from ZnSO(4) and 16.5 mg/kg of Cu from CuSO(4). In Exp. 1, treatments we...

Organic amendments often represent a source of trace metals (TMs) in soils, which may partly leach into the groundwater. The objectives of this study were (1) to validate Hydrus-2D for modeling the transport of Zn and Cu in an Alfisol amended with pig slurry (PS) by comparing numerical simulations and experimental field data, and (2) to model the next 50 years of TM movements under scenarios of...
