As the major iron storage protein, ferritin stores and releases iron for maintaining the balance of iron in fauna, flora, and bacteria. We present an investigation of the morphology and iron loading of ferritin (from equine spleen) using aberration-corrected high angle annular dark field scanning transmission electron microscopy. Atom counting method, with size selected Au clusters as mass stan...

In a high mountain lake and catchment area, a natural process of phosphorus enrichment is observed, induced by the iron-cycle. Investigations focus on the speciation of P and Fe in iron and manganese rich oxidic mineral crusts formed at the surface of rock pebbles. Iron and phosphorus are spatially associated although they are not forming iron phosphate minerals. While Fe and P K edge XAS spect...

OBJECTIVE To describe the frequency of anemia and iron, zinc, copper and magnesium deficiencies among Mexican adolescents in the probabilistic survey ENSANUT 2006. MATERIALS AND METHODS The sample included 2447 adolescents aged 12 to 19 y. Capillary hemoglobin and venous blood samples were collected to measure the concentrations of ferritin, sTFR, CRP, zinc, iron, copper and magnesium. Logist...

Ninety, day old broiler chicks were arranged into 5X3X6 pattern to investigate the effect of exclusion of Cobalt, Iron and Copper from the mineral mixture. Five dietary groups (T1 to T5) were assigned basal diets containing 2800 kcal ME/kg and 22% CP (Starter) and 20% (Finisher) for a total duration of 6 weeks. The chicks in T1 were fed commercial mineral mixture, T2 were supplemented with mine...

Natural products with important therapeutic properties are known to be produced by a variety of soil bacteria, yet the ecological function of these compounds is not well understood. Here we show that phenazines and other redox-active antibiotics can promote microbial mineral reduction. Pseudomonas chlororaphis PCL1391, a root isolate that produces phenazine-1-carboxamide (PCN), is able to reduc...

The purpose of this study is twofold: to examine macro (calcium, magnesium, and phosphorus) and trace mineral (iron) concentration in oriental supplements (OS), and to define OS prevalence in elite athletes. Participants of this study were 928 varsity athletes (male: 680, female: 248) with 23 sports types. Recent 3-month dietary supplements (DS) and OS practice was surveyed during training peri...

BACKGROUND Use of illicit drugs induces multiple nutrient deficiencies. Drug habit, sexual practice and socioeconomic factors influence the nutrient profile of drug dependent subjects. The literature on this issue is still insufficient. This study has tested the hypothesis that illicit drug use and lifestyle impair mineral status. To test this hypothesis, 253 men multiple drug users of age 18-4...

Influence of mineral water from Trenčianske Teplice (drinkable source) on lipid peroxidation processes was determined in model situations under in vitro conditions using the brain tissue. The central nervous system was selected because it is especially sensitive to the radical-induced damage. In addition, there is a high content of polyunsaturated fatty acids in the brain which has a low antiox...

As more data are accumulated it becomes increasingly evident that great variations exist in the mineral content of different samples of the same foodstuff. Only when a large number of samples from different parts of the country have been analyzed will it be possible to approximate the probable mineral content of our diet. With the data now available it is difficult to draw any safe conclusion a...
