Background: Boron and gadolinium are among the nuclides that hold a unique property of being a neutron capture therapy agent. Neutron beams have often a considerable portion of gamma rays with fast neutrons. Gamma rays, as beam contaminants, can cause considerable damage to normal tissues even if such tissues do contain high boron concentrations. Materials and Methods: The modification of radio...

In this issue of the Netherlands Journal of Medicine, Kampen et al. describe a patient with a hepatic angiosarcoma resulting from exposure to Thorotrast. Thorotrast was developed in 1928 and used as a radiocontrast agent in the period 1930 to 1960. Thorotrast is a colloidal solution containing the naturally occurring radionuclide Thorium. Thorotrast particles are deposited in the reticulo-endot...

"4f hybridization and band dispersion in gadolinium thin films and compounds"

Gadolinium-based contrast agents are increasingly being used in magnetic resonance imaging. These agents can improve the contrast in images and provide information about function and metabolism, increasing both sensitivity and specificity. We describe the gadolinium-based contrast agents that have been approved for clinical use, detailing their main characteristics based on their chemical struc...

In neutral media, reactions of gadolinium ethylenediaminetetraacetates with phosphorous acid result in the formation of the mixed-ligand polymeric complex K3n[Gd(EDTA)(HPO3)]n·7nH2O () and dimeric complex Na6[Gd2(EDTA)2(HPO3)2]·2.5NaCl·21H2O () (H4EDTA = ethylenediaminetetraacetic acid) in warm solution. Further substitution with citric acid gives the monomeric gadolinium citrate with EDTA (NH4...

Since thermoelectrics are an important way to produce electricity from waste heat, the thermoelectric properties of gadolinium copper telluride, GdCuTe2, together with the doped compounds gadolinium samarium copper telluride, Gd1-xSmxCuTe2, and gadolinium dysprosium copper telluride, Gd1-xDyxCuTe2, with x = 0.02 and x = 0.05 were investigated. Upon doping, a decrease in thermal conductivity and...

The electrical and magnetic properties were measured on polycrystalline samples of niobium diselenide intercalated with gadolinium atoms. dependences the resistance temperature point to a predominantly phonon scattering mechanism for charge carriers, while concentration are determined by increasing interstitial Gd x NbSe 2 (0≤ x≤0.33) studied in range 2-350 K fields up 70 kOe. Based results stu...

To develop an estimation method of gadolinium magnetic resonance imaging (MRI) contrast agents, the effect of concentration of Gd compounds on the ESR spectrum of nitroxyl radical was examined. A solution of either 4-oxo-2,2,6,6-tetramethylpiperidine-N-oxyl (TEMPONE) or 4-hydroxy-2,2,6,6-tetramethylpiperidine-N-oxyl (TEMPOL) was mixed with a solution of Gd compound and the ESR spectrum was reco...

The current study aims to explore how the gadolinium (Gd)-based contrast agent (GBCA) Omniscan® enhanced cell viability of murine fibroblasts. The results of scanning electron microscopy showed that Omniscan® can precipitate in cell culture media and deposit on cell membranes. Energy-dispersive X-ray analysis and Fourier-transform infrared spectroscopy demonstrated the presence of Gd and phosph...
