An animal model to study iron availability from human diets

An animal model to study iron availability from human diets.

1. The retention of ferric- and ferrous-iron was determined in guinea-pigs and monkeys using 55Fe and 59Fe. 2. The bioavailability of Fe from two typical Indian diets based on rice and wheat was determined in humans and monkeys using a 59Fe tracer and whole-body counting. 3. The retention ratio, ferric-Fe; ferrous-Fe was 0-90 in guinea-pigs and 0-33 in monkeys, indicating that monkeys absorb fe...

Exposure to Radiofrequency Radiation Emitted from Common Mobile Phone Jammers Alters the Pattern of Muscle Contractions: an Animal Model Study

Introduction: The fast-growing telecommunication and wireless technologies has led to more dependence to these communication devices and higher levels of exposure to electromagnetic radiations propagated by cellular devices and their service towers. To disable signaling in places where silence is valued or where information quarantine measures are required, mobile phone jammers emit radiofreque...

Iron availability from iron-fortified spirulina by an in vitro digestion/Caco-2 cell culture model.

Iron deficiency, one of the most important nutritional problems in the world, can be caused not only by foods deficient in iron but also by poor availability of dietary iron. Iron food fortification in combination with highly available iron from supplements could effectively reduce this deficiency. The aim of this study was to examine the iron availability from iron-fortified spirulina. We have...

Availability of iron from iron-storage proteins to marine phytoplankton

We examined the bioavailability of iron-storage proteins—including representatives of maxiand miniferritins—to various species of marine phytoplankton. Both eukaryotic and prokaryotic species were able to grow rapidly with horse spleen ferritin (HoSF) or deoxyribonucleic acid (DNA)-binding proteins from starved cells (Dps) from Trichodesmium erythraeum as the sole Fe source in the medium. In th...
