OBJECTIVE Malabsorption is one of the causes of iron deficiency anemia in postmenopausal women. The main objective of this study was to access the frequency of malabsorption in iron deficient anemic postmenopausal women. METHODS A total of 123 postmenopausal women were enrolled in the study. Of these 123 women, 50 were included as 'control group' and 73 patients with comparable severity of an...

Ground water systems dominated by iron- or sulfate-reducing conditions may be distinguished by observing concentrations of dissolved iron (Fe(2+)) and sulfide (sum of H(2)S, HS(-), and S(=) species and denoted here as "H(2)S"). This approach is based on the observation that concentrations of Fe(2+) and H(2)S in ground water systems tend to be inversely related according to a hyperbolic function...

Melioidosis is highly prevalent in Northeast Thailand which is associated with high incidence of Burkholderia pseudomallei present in the soil of this region. B. pseudomallei when present in biofilm becomes resistant to numerous environmental factors and also to certain antibiotics. In this study, we examined the effects of several environmentally relevant factors (salinity, iron, manganese and...

Background and Objectives: In the original in vitro method for evaluation of iron bioavailability using caco-2 cell model, ferritin formation by cells is considered as a functional indicator of both absorption and utilization of iron. However, as iron is measured in the tested material and then ferritin concentration is measured in caco-2 cell lysate, it is almost impossible to have a concrete ...

The objective of the study was to evaluate the iron bioavailability of iron amino acid complex, Availa-Fe compound, as compared to the iron from feed grade ferrous sulfate in weanling piglets. Seventy-two 30-day-old three-way cross piglets, with an average live-weight of 6.41 kg, were randomly allocated into 12 groups of six dietary treatments and two replicates. The control diet (C) included 1...

Introduction: The discovery of ferric hydroxides/oxyhydroxides, jarosites (iron-bearing sulfates thought to have formed via aqueous activity) and other sulfate-bearing minerals in the Meridiani region provides strong evidence that liquid water once flowed on the Martian surface [1-3]. It is suggested that sulfate deposits enriched in iron and mixed iron oxyhydroxide were precipitated form meltw...

The present study was conducted to examine different dietary levels of iron (FeSO4) on some haematological parameters of ship sturgeon, Acipenser nudiventris including red blood cells (RBC), white blood cells (WBCs), differential WBCs, hematocrit (Hct), Hemoglobin (Hb), the mean corpuscular hemoglobin (MCH) and the mean corpuscular hemoglobin concentration (MCHC), the mean corpuscular volume (M...

In a field experiment at Vandenberg Air Force Base (VAFB) designed to mimic the impact of a small-volume release of E10 (10% ethanol and 90% conventional gasoline), two plumes were created by injecting extracted groundwater spiked with benzene, toluene, and o-xylene, abbreviated BToX (No-Ethanol Lane) and BToX plus ethanol (With-Ethanol Lane) for 283 days. We developed a reactive transport mode...

A total of 1110 broiler cockerels were used in three experiments to determine the availability of iron and copper from various sources. A skim milk basal diet was fed in each experiment using chicks maintained in battery brooders beginning at one day of age. Four organic iron compounds (sequestered iron A' and ferric choline chloride in Experiment 1 and sequestered iron B and C in Experiment 2)...

Hepcidin, a peptide hormone, is a key regulator in mammalian iron homeostasis. Increased level of hepcidin due to inflammatory conditions stimulates the ferroportin (FPN) transporter internalization, impairing the iron absorption; clinically manifested as anemia of inflammation (AI). Inhibiting hepcidin-mediated FPN degradation is proposed as an important strategy to combat AI. A systematic app...
