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 ...
