On the assumption that rare earth elements (REEs) are nontoxic, they are being utilized as replacements of toxic heavy metals in novel technological applications. However, REEs are not entirely innocu...Read More
The synthesis and spectroscopic investigation of Pr(3+):YF(3) nanoparticles with nominal concentration between 0.05% and 5 at% Pr(3+) are reported. Pr(3+) emission in the visible range of the spectrum...Read More
The effective interactions and phase behavior of protein solutions under strong electrostatic coupling conditions are difficult to understand due to the complex charge pattern and irregular geometry o...Read More
Acceleration of the Substitution of Silanes with Grignard Reagents by Using either LiCl or YCl(3)/MeLi.

Preparation of porous yttrium oxide microparticles by gelation of ammonium alginate in aqueous solution containing yttrium ions.
Porous Y2O3 microparticles 500 microm in size were obtained, when 1 wt%-ammonium alginate aqueous solution was dropped into 0.5 M-YCl3 aqueous solution by a Pasteur pipette and the resultant gel micro...Read More
Negatively charged globular proteins in solution undergo a condensation upon adding trivalent counterions between two critical concentrations C and C, C...Read More
Effects of intratracheal pretreatment with yttrium chloride (YCl3) on inflammatory responses of the rat lung following intratracheal instillation of YCl3.
We investigated pulmonary clearance of yttrium (Y) and acute lung injury following intratracheal instillation (i.t.) of yttrium chloride (YCl3) in saline- or YCl3-pretreated rats (30 days before the s...Read More
Possibilities to exercise an influence on the biodistribution of a tumor-affine 153Sm-preparation, samarium-153-nitrilotriacetate (NTA), were tested....Read More
Although radioactive yttrium (Y) has been used for medical treatment, little attention has been directed toward the toxicity of Y. We report time-course and dose-related changes in tissue distribution...Read More
Distribution, localization, and pulmonary effects of yttrium chloride following intratracheal instillation into the rat.
Metabolic behavior and pulmonary toxicity of yttrium chloride (YCl3) deposited in the lung was investigated. Yttrium chloride was instilled intratracheally into rats and the time-course and dose-relat...Read More
Preparation of ^9^0YCl"3 radiopharmaceutical precursor for nuclear medicine using technology of centrifugal extractors
Separation of ^9^0Y from a parent solution of ^9^0Sr-^9^0Y in 0.5M nitric acid by two-stage liquid-liquid extraction has been investigated using centrifugal extractors. The extraction agent used was 0...Read More
Optical imaging (OI) techniques such as bioluminescence and fluorescence imaging have been widely used to track diseases in a non-invasive manner within living subjects. These techniques generally req...Read More
Convenient method for the rapid generation of highly active and enantioselective yttrium catalysts for asymmetric hydroamination.
A facile method for the preparation of highly active and enantioselective yttrium precatalysts for asymmetric hydroamination of gem-disubstituted aminoalkenes, from the combination of YCl(3) or YCl(3)...Read More
The efficacy of diethylenetriaminepentaacetate calcium trisodium (CaNa(3)DTPA) in a dose of 34.7 micromol kg(-1) as a function of its route of administration was investigated in rats with a puncture w...Read More
A Straightforward Method for Analysis of Highly Phosphorylated Inositols in Blood Cells by High-Performance Liquid Chromatography
Soluble inositol polyphosphates are found in many cells. The trisphosphate isomers, mainly inositol-1,4,5-trisphosphate, have been extensively studied because of their involvement in signal transducti...Read More
