Absolute measurements of the radiolytic yield of Fe3+ in a ferrous sulphate dosimeter formulation (6 mM Fe2+), with a 20 keV x-ray monoenergetic beam, are reported. Dose-rate suppression of the radiolytic yield was observed at dose rates lower than and different in nature to those previously reported with x-rays. We present evidence that this effect is most likely to be due to recombination of free radicals radiolytically produced from water. The method used to make these measurements is also new and it provides radiolytic yields which are directly traceable to the SI standards system...

Two Fricke-based absorbed dose to water standards for HDR Ir-192 dosimetry, developed independently by the LCR in Brazil and the NRC in Canada have been compared. The agreement in the determination of the dose rate from a HDR Ir-192 source at 1 cm in a water phantom was found to be within the k=1 combined measurement uncertainties of the two standards: D<sub>NRC</sub>/D<sub>LCR</sub> = 1.011, standard uncertainty = 2.2 %. The dose-based standards also agreed within the uncertainties with the manufacturer's stated dose rate value, which is traceable to a national standard of air kerma...

BACKGROUND: Iron food fortification and oral iron formulations are frequently limited by poor absorption, resulting in the widespread use of high-dose oral iron, which is poorly tolerated. METHODS: We evaluated novel iron-denatured whey protein (Iron-WP) microspheres on reactive oxygen species (ROS) and viability in gut epithelial (HT29) cells. We compared iron absorption from Iron-WP versus equimolar-dose (25 mg elemental iron) ferrous sulphate (FeSO4) in a prospective, randomised, cross-over study in fasting volunteers (n = 21 per group) dependent on relative iron depletion (a ferritin level ≤/>30 ng/mL)...

BACKGROUND: Approximately 600 million children of preschool and school age are anaemic worldwide. It is estimated that at least half of the cases are due to iron deficiency. Point-of-use fortification of foods with micronutrient powders (MNP) has been proposed as a feasible intervention to prevent and treat anaemia. It refers to the addition of iron alone or in combination with other vitamins and minerals in powder form, to energy-containing foods (excluding beverages) at home or in any other place where meals are to be consumed...

Iron is implicated in age-related macular degeneration (AMD). The aim of this study was to see if long-term, experimental iron administration with aging modifies retinal and choroidal structures and expressions of iron handling proteins, to understand some aspects of iron homeostasis. Male Wistar rats were fed with ferrous sulphate heptahydrate (500mg/kg body weight/week, oral; elemental iron availability: 20%) from 2 months of age onward until they were 19.5 month-old. At 8, 14 and 20 months of age, they were sacrificed and serum and retinal iron levels were detected by HPLC...

Micronutrient deficiencies result in irreversible physical and cognitive consequences. Fortification of flour is widely applied to address micronutrient deficiencies, but vitamin losses can occur during the storage of fortified products. This work aimed at assessing the combined influence of different factors on vitamin A retention and the oxidative status of wheat flours: storage duration (up to 6months), temperature during storage, relative humidity within storage facilities, type of packaging (oxygen-permeable or not), and premix composition (with or without ferrous sulphate)...

Metronidazole is administered in an inactive form then activated to its cytotoxic form within the hydrogenosome of trichomonads. Two hydrogenosomal proteins, pyruvate ferredoxin oxidoreductase (PFOR) and ferredoxin, play a critical role in the reductive activation of metronidazole. The expression of these proteins and other hydrogenosomal proteins are likewise positively regulated by iron. In the present study, the effect of iron on minimal lethal concentration (MLC) of metronidazole on in vitro cultured Trichomonas vaginalis(T...

This study examined the bioavailability of iron contained in microencapsulated ferric saccharate in a rat model of iron deficiency anaemia. Three groups of male Sprague-Dawley rats with induced iron deficiency anaemia were subsequently treated with a control Fe-deficient diet (2-6 mg Fe/Kg of diet) with or without the addition of 10 mg Fe/Kg of diet (in form of ferrous sulphate or microencapsulated ferric saccharate) for 2 weeks. The bioavailability of microencapsulated ferric saccharate was examined by measuring body weight gain, feed efficiency and reticulocyte parameters, and compared with the bioavailability of ferrous sulphate...

The oxidation potential of iron fortified goat and cow milks and casein phosphopeptides obtained from each species of milk was determined using malondialdehyde as an oxidation product marker. There was a reduction in oxidation when iron was 'bound' to milk or peptides compared to free ferrous sulphate in solution. However, goat milk produced significantly lower amounts of malondialdehyde of 0.46±0.04μgMDA/ml after 3days at 30°C compared to the blank of 1.25±0.16μgMDA/ml. The goat peptides produced non-significantly different levels of malondialdehyde compared to the blank containing no ferrous sulphate...

Numerous iron-containing preparations are available on the market; these vary in dosage, salt, chemical state of iron (ferric or ferrous) and in the iron delivery process (immediate or prolonged-release). Tardyferon® is a prolonged-release tablet containing 80 mg ferrous sulphate. The formulation has recently been modified; changes to the excipients which constitute the inert formulation matrix have allowed a decrease in tablet size for easier swallowing. The aim of this multicenter open-label study was to characterize the serum pharmacokinetics of iron in non-pregnant women aged 23-45 years with iron deficiency anaemia (IDA) following single oral administration of 160 mg Tardyferon® under fasting conditions...

Recent studies have shown that the pyrolysis of biomass combined with clay can result in both lower cost and increase in plant yields. One of the major sources of nutrients for pasture growth, as well as fuel and building materials in Tibet is yak dung. This paper reports on the initial field testing in a pasture setting in Tibet using yak dung, biochar, and attapulgite clay/yak dung biochars produced at ratios of 10/90 and 50/50 clay to dung. We found that the treatment with attapulgite clay/yak dung (50/50) biochar resulted in the highest pasture yields and grass nutrition quality...
