BACKGROUND/OBJECTIVES Korean ordinary diets are referred to be good for human health in worldwide. However it is uncertain whether they provide microminerals enough for growth and health of teenagers. A main purpose of this study was to identify micromineral contents in school meals. MATERIALS/METHODS The fifty cuisines were collected from elementary schools and middle schools in Gyeongnam ar...

BACKGROUND & OBJECTIVES Relationship of trace elements with obesity and diabetes is complex, alterations in their metabolism can be induced by the diseases and their complications. To study the role of the trace elements in diabetes and obesity, serum trace elements levels (Cr, Se, Fe, Zn, Cu and Mn) were measured in obese women with or without diabetes as well as healthy women. Further, correl...

Concentrations of some heavy metals (Fe, Zn, Cu, Mn and Cr) in liver of pike (Esox lucius L., 1758) and its endoparasite [Raphidascaris acus (Bloch, 1779)] inhabiting Işikli Lake (Turkey) were analyzed using atomic absorption spectrophotometry. Only Fe and Zn were detected in R. acus and liver of fish, while levels of Cu, Mn and Cr were below detection limit (<0.028). The Fe and Zn level in R. ...

Metallic iron (Fe) is often reported as a reducing agent for environmental remediation. There is still controversy as to whether Fe plays any significant direct role in the process of contaminant reductive transformation. The view that Fe is mostly a generator of reducing agents (e.g. H, H2 and Fe) and Fe oxyhydroxides has been either severely refuted or just tolerated. The tolerance is based o...

A growth experiment with 108 lambs (breed: German Merino Landsheep) was carried out to examine the effect of gender, body weight (BW) and feeding intensity on the deposition of Fe, Zn, Cu and Mn in the empty body (whole animal minus contents of the gastrointestinal tract and bladder). The lambs (50% female and 50% male animals) were fed at three feeding levels ('low', 'medium' and 'high' by var...

an experiment was conducted in the experimental field of seed and plant improvement institute in karaj for three consecutive cropping seasons, 2001-2003, to study the effects of eight different fertilizer treatments including some microelements on grain yield and protein content of a bread wheat cultivar pishtaz. the experiment was in a rcbd with three replications.eight fertilizer treatments w...

In a 36-d experiment, 32 pigs were depleted of Zn (24 d) using a soy-isolate (basal) diet (17 mg/kg of Zn) and then fed the basal diet (12 d) supplemented with 45 mg/kg of Zn from ZnSO4 (purified zinc sulfate dry powder, ZnSO4.nH2O) or from a Zn amino acid chelate (ZnAAC) to study the effectiveness of these dietary Zn sources in restoring serum and soft tissue Zn concentrations. Concurrently, n...

The quality of edible seeds for human and animal nutrition is crucially dependent on high zinc (Zn) and iron (Fe) seed concentrations. The micronutrient bioavailability is strongly reduced by seed phytate that forms complexes with seed cations. Superior genotypes with increased seed Zn concentrations had been identified, but low micronutrient seed levels often prevail when the plants are grown ...

We describe the intracellular distributions of nine essential elements (P, S, Cl, K, Ca, Mn, Fe, Cu, and Zn) found in cardiomyocytes imaged using synchrotron X-ray induced fluorescence. Cardiomyocytes were isolated from rat hearts, flash frozen on Si(3)N(4) windows, freeze-dried, and imaged with approximately 300 nm spatial resolution. Distinct longitudinal patterns in cardiomyocytes were most ...

Zinc represents the most effective and economic corrosion protection especially for steel base materials. Improved corrosion resistance can be achieved by alloying zinc with small amounts (around 1 Yo) of transition metal elements like Co, Ni and Fe. Zn-Fe and Zn-Co alloys containing up to 1.5 Yo of the transition metal were plated using an alkaline and acidic electrolyte respectively. Zn-Ni al...
