Subject:
aluminum; capillary electrophoresis; endocytosis; humans; hydrodynamics; ions; iron; light scattering; pH; toxicity; transferrin
Abstract:
... Human transferrin (Tf) very tightly binds two ferric ions to deliver iron to cells. Fe(III)₂Tf (Fe₂Tf) binds to the Tf receptor (TfR) at pH 7.4; however, iron-free Tf (apoTf) does not. Iron uptake is facilitated by endocytosis of the Fe₂Tf-TfR complex. Tf can also bind aluminum ions, which cause toxic effects and are associated with many diseases. Since Al(III)₂Tf (Al₂Tf) does not bind to TfR, the ...

Abstract:
... Aluminum toxicity is one of the major soil factors limiting root growth in acidic soils. Because of the increase in organic matter content in the upper few centimeters of soils under no-till systems (NTS), most Al in soil solution may be complexed to dissolved organic C (DOC), thus decreasing its bioavailability. The aim of this study was to evaluate the effects of surface liming on Al speciation ...

Abstract:
... In vitro studies are reported of the behaviour of potassium aluminosilicate inorganic polymers containing 10 wt% Ca(OH)₂, nanostructured calcium silicate and Ca₃(PO₄)₂ exposed to simulated body fluid (SBF). Heating to 600 °C lowers the alkalinity of Ca₃(PO₄)₂-containing samples, but their X-ray powder diffraction characteristics, ²⁷Al, ²⁹Si and ⁴³Ca MAS NMR spectra are unchanged by heating. Exposu ...

Abstract:
... Pretreatment with chemicals such as ethylenediaminetetraacetic acid (EDTA) is often used to improve the analysis of sediment P with solution P-31 nuclear magnetic resonance spectroscopy (³¹P-NMR), but there is a lack of a comprehensive assessment of the methodology. In this study, the effects of EDTA pretreatment on sediment P extracted using a mixture of 0.25 mol L⁻¹ NaOH and 50 mmol L⁻¹ EDTA (Na ...

Bioavailability of P substantially differed among the lakes due to differences in their P loading, as well as in concentrations of aluminum (Al) and its species, and was accompanied by species-specific responses of phytoplankton. We comb ...

For Al at pH 3, sorption was less than the available sorption sites (i.e., the cation exchange capacity) on all three sor ...
