BACKGROUND High levels of circulating fibroblast growth factor 23 (FGF23) are associated with chronic kidney disease (CKD) progression and high mortality. In the Phosphate Reduction Evaluation of FGF23 in Early CKD Treatment (PREFECT) study, we assessed the effect of reducing intestinal phosphate absorption using lanthanum carbonate on FGF23 levels in normophosphatemic patients with CKD stage 3...
Phosalone, malathion and diazinon were analyzed in corn oil using solid phase extraction (SPE)with lanthanum silicate as a new solid sorbent followed by gas chromatography with nitrogenphosphorus detection (GC-NPD). The efficiency of different eluents (methanol, dichloromethane,ethyl acetate, dichloromethane — ethyl acetate (1:1) and ethyl acetate — methanol (1:1)) werecompared for elution of o...
In this article, adsorption of some amino acids and their complexation with lanthanum(III) ion on carbon nanotube (MWCNT) by using of three relations Langmuir, Freundlich and Temkin isotherms was investigated. From this relations, Freudlich and Temkin relations predict good equilibrium diagram in isotherm condition. We could compute the theoretical constants by excel software. By considering th...

La(21)Ru(9+x)In(5-x) (Pearson symbol tI140) is isotypic to the filled Y(3)Rh(2)-type structure, from which it can be derived through an ordered substitution at two sites. One of the square-prismatic sites (site symmetry ..m) is occupied by a mixture of Ru and In atoms and one of the square-antiprismatic sites (4/m..) is fully occupied by In atoms.

New complexes of coumarin-3-carboxylic acid (HCCA) with holmium [Ho(III)] and erbium [Er(III)] were synthesized and their structures and spectral properties were investigated by elemental analysis, IR, Raman and NMR measurements. According to the experimental data of the complexes, their formulae and geometries have been suggested. Vibrational frequencies, IR intensities and Raman activities as...
