Population satiety with trace elements (TE) is a problem that is widely discussed in nutrition science. For optimal nutrition, the form of TE eaten in food is very important. Organic forms of TE in nutrition are appropriate as human metabolism has adapted to these kinds of nutrients during species evolution. ...

The Biwabik Iron Formation is a approximately 1.9 billion year-old sequence of iron-rich sedimentary rocks that was metamorphosed at its eastern-most extent by approximately 1.1 billion year-old intrusions of the Duluth Complex. The metamorphic recrystallization of iron-formation locally produced iron-rich amphiboles and other fibrous iron-silicate minerals. The presence of these ...

Deferiprone is only a second-line option for the treatment of iron overload. The convenience of oral intake does not compensate for the lack of evidence concerning effects on morbidity and/or mortality. In contrast, deferoxamine, an injectable product, has proven clinical efficacy. However, seven years after initial marketing of deferiprone, its ...

Ferritins are iron-storage proteins involved in the regulation of free iron levels in the cells. Arabidopsis thaliana AtFer1 ferritin, one of the best characterized plant ferritin isoforms to date, strongly accumulates upon treatment with excess iron, via a nitric oxide-mediated pathway. However other environmental factors, such as exposure to oxidative ...

Iron deficiency and iron deficiency anemia continue to be significant public health problems worldwide. While supplementation and fortification have been viable means to improve iron nutriture of the population in developed countries, they may be less successful in developing regions for a number of reasons, including complexities in distribution and ...

The assessment of dietary zinc intakes is an important component of evaluating the risk of zinc deficiency in populations, and for designing appropriate food-based interventions, including fortification, to improve zinc intakes. The prevalence of inadequate zinc intakes can describe the relative magnitude of the risk of zinc deficiency in the ...

Exotic slugs have become serious pests of canola, at establishment, in Southern Australian high-rainfall cropping zones. Slugs were monitored using relatively inexpensive 300 mm x 300 mm terracotta tiles acting as refuges. An investigation was made of the effects of the time of application of chelated iron baits on the ...

BACKGROUND: Anemia is a significant public health problem among schoolchildren in Vietnam. Food fortification is considered one of the most sustainable long-term strategies to control iron-deficiency anemia in Vietnam. The success of a food-fortification program depends on the choice of the food vehicle. OBJECTIVES: The aim of the present study ...

(+)-Pisatin, the major phytoalexin of pea (Pisum sativum L.), is believed to be synthesized via two chiral intermediates, (-)-7,2'-dihydroxy-4',5'-methylenedioxyisoflavanone [(-)-sophorol] and (-)-7,2'-dihydroxy-4',5'-methylenedioxyisoflavanol [(-)-DMDI]; both have an opposite C-3 absolute configuration to that found at C-6a in (+)-pisatin. The expression of isoflavone reductase (IFR), which converts 7,2'-dihydroxy-4',5'-methylenedioxyisoflavone (DMD) to (-)-sophorol, sophorol ...

Iron deficiency is one of the leading risk factors for disability and death worldwide, affecting an estimated 2 billion people. Nutritional iron deficiency arises when physiological requirements cannot be met by iron absorption from diet. Dietary iron bioavailability is low in populations consuming monotonous plant-based diets. The high prevalence of ...

The dietary constituents that may act, in the broadest sense, as co-factors to enable bacterial enteropathogens to replicate in gastrointestinal environments are still largely unknown. Recent work has demonstrated that certain non-nutritional components of food, such as the catecholamines, can contribute to the ability of Gram-negative pathogens to replicate in ...

Food and nutrition professionals provide medical nutrition therapy for patients with kidney stones. If the stones contain oxalate or the patient has been diagnosed with hyperoxaluria, reduction of dietary oxalate may be appropriate. Differences in oxalate values for a single food may be due to analytical methods, and/or biological variation ...

The ferroportin polymorphism SLC40A1 Q248H (exon 6, cDNA 744G-->T; Gln248His) occurs in persons of sub-Saharan African descent with and without iron overload, and is associated with elevated serum ferritin concentrations (SF). However, the risk of iron overload associated with Q248H has not been defined. We tabulated previously reported Q248H allele ...

The bioavailability (relative bioavailability value; RBV) of iron compounds relative to ferrous sulfate has proven useful in ranking the potential of iron compounds for food fortification. The efficacy of iron-fortified foods however depends on the absolute iron absorption from the fortified food and not on the RBV of the iron ...

Inadequate dietary intake, often combined with an infection can lead to malnutrition that often manifest as growth failure or deficiency of essentials nutrients including iron leading to iron deficiency anaemia. In an effort to investigate diet in relation to nutrition status of children, diet and dietary intake were investigated in ...

Zinc fortification is considered a potentially useful strategy for the control of zinc deficiency, but the success of such intervention programs depends on the population's access to and consumption of zinc-fortified foods and adequate absorption of zinc from these foods. The latter issue has been assessed by a variety of ...

The availability of iron limits primary productivity and the associated uptake of carbon over large areas of the ocean. Iron thus plays an important role in the carbon cycle, and changes in its supply to the surface ocean may have had a significant effect on atmospheric carbon dioxide concentrations over ...

Taking into account the strong iron competition in the rhizosphere and the high affinity of pyoverdines for Fe(III), these molecules are expected to interfere with the iron nutrition of plants, as they do with rhizospheric microbes. The impact of Fe-pyoverdine on iron content of Arabidopsis thaliana was compared with that ...

To develop an algorithm to predict the percentage non-heme iron absorption based on the foods contained in a meal (wholemeal cereal, tea, cheese, etc.). Existing algorithms use food constituents (phytate, polyphenols, calcium, etc.), which can be difficult to obtain. A meta-analysis of published studies using erythrocyte incorporation of radio-isotopic iron ...

Zerovalent iron (Fe(0), ZVI) has drawn great interest as an inexpensive and effective material to promote the degradation of environmental contaminants. A focus of ZVI research is to increase degradation kinetics and overcome passivation for long-term remediation. Halide ions promote corrosion, which can increase and sustain ZVI reactivity. Adding chloride ...

In a previous study, antler bone chemical composition was found to differ between base and tip. If such variation is in part due to the physiological effort made to grow the antler, composition trends should differ between antlers from deer population differing in mineral or food availability, or body reserves. ...

Since n-octanol, a long-chain alkanol, presents a configuration similar to that of carbohydrates and lipids, the lipophilicity and absorptivity of organic medicines may be assessed from their distribution coefficients between octanol and water. n-octanol is used as a model of biomembrane. This strategy has been used in order to define ...

Naturally occurring and chemically modified ribonucleosides have interesting bioactive effects. Dietary ribonucleosides are ingested mainly as nucleoproteins and are converted in the course of intestinal digestion to monomeric compounds. Different bioactive effects of dietary ribonucleosides have been described, including the ability to enhance gut growth and maturation and to increase ...

Monodisperse crystalline zero-valent iron, iron-nickel, iron-palladium nanowires were synthesised using template-directed electrodeposition methods. Prior to nanowire fabrication, alumina nanotemplates with controlled pore structure (e.g. pore diameter and porosity) were fabricated by anodising high purity aluminium foil in sulphuric acid. After fabrication of alumina nanotemplates, iron, iron-nickel and iron-palladium nanowires were ...
