Iron (Fe) loaded solid lipid nanoparticles (SLN's) were formulated using stearic acid and iron absorption was evaluated in vitro using the cell line Caco-2 with intracellular ferritin formation as a marker of iron absorption. Iron loading was optimised at 1% Fe (w/w) lipid since an inverse relation was observed between initial iron concentration and SLN iron incorporation efficiency. Chitosan (...

A variety of compounds which bind to Fe have substantial reductions in absorption when co-administered with Fe compounds. The binding of both Fe2+ and Fe3+ ions to pteroylmonoglutamic acid and the pteroylmonoglutamate dianion was examined in vitro. In dimethylsulphoxide (DMSO) alone, pteroylmonoglutamate formed a 2:1 (pteroylmonoglutamate:Fe3+ ion) complex. However, in DMSO-aqueous Bis-Tris buf...

I . Iron absorption from rice-containing meals was measured by red cell utilization of radioactive Fe in sixty-six voluntcer multiparous Jndian women. 2. In all the studies salt added during the cooking process wiis used as the carrier for supplemental inorganic Fe and ascorbic acid. 3. Intrinsic Fe in the rice and supplementary inorganic Fe were absorbed to the same extent, with a wide range o...

detected with sodium dodecyl sulphate/polyacrylamide slab gels. This material, which has an apparent mol.wt. of at least 500000, is stained by the periodic acid/Schiff reagent. Preliminary studies show that galactose is incorporated into this substance most rapidly in the early stages of culture (0-36h) and again after fusion has occurred (6096 h). Other workers have reported that the large, ex...

Protein fractions that bind retinol were isolated from the cytosol, nucleosol and chromatin of the oviduct magnum of laying hens. The proteins isolated from the three sources showed similar elution profiles on chromatography through Sephadex G-75 and G-50 columns, and comparable mobility during electrophoresis on sodium dodecyl sulphate/polyacrylamide gels. Their molecular weights were calculat...

The aim of this study is to investigate the effects different rates N, Mg and Fe applications on mineral content parsley leaves. experiment was carried out in a greenhouse according randomized plot design with three replications. Seven dose treatments were designed as 130, 160, 190, 220, 250, 280 310 kg per ha N ammonium nitrate (33% N), 40, 80, 120, 200, 240 magnesium sulphate (16% MgO) 8, 16,...

Pre-photosynthetic niches were meagre with a productivity of much less than 10(-4) of modern photosynthesis. Serpentinization, arc volcanism and ridge-axis volcanism reliably provided H(2). Methanogens and acetogens reacted CO(2) with H(2) to obtain energy and make organic matter. These skills pre-adapted a bacterium for anoxygenic photosynthesis, probably starting with H(2) in lieu of an oxyge...

BACKGROUND Gastrointestinal irritability can deter pregnant women from starting or continuing prenatal multivitamin supplementation. In a previous study, suboptimal tolerability was observed among pregnant women taking a large tablet (18 mm x 8 mm x 8 mm) multivitamin with high elemental iron content (60 mg as ferrous fumarate). The objective of the present study was to compare rates of adheren...

Amyloid fibrils were isolated by extraction in water from the livers and spleens of four patients who had died of monoclonal, light-chain (AL)-type, systemic amyloidosis and one with reactive systemic, amyloid A protein (AA)-type amyloidosis. Each fibril preparation contained 1-2% by weight of glycosaminoglycan (GAG) which was tightly associated with the fibrils and not just co-isolated from th...
