A new fluoride releasing resin-ionomer cement was used for bonding of gallium alloy restorations in vitro. Etching, priming, and fluoride releasing resin-ionomer cement were used in the experimental group (ARG), prior to placement of the gallium alloy restorations. Three different controls were used: gallium alloy only (G), no etching, fluoride releasing resin-ionomer cement, gallium alloy (RG)...

Gallium-67 citrate has long been used for imaging of infection and inflammation. Although gallium-67 uptake due to silicone implants and silicone injections has been previously reported in the literature, very few cases are documented. We report a case of increased gallium-67 uptake in the buttocks in a patient who previously received silicone injections in the buttocks, to reemphasize silicone...

background: in addition to determining the exact tumor location and its geometric features, an increase of the effective tumor atomic number will enhances the chance in treating the tumoral cells under suitable radiation. in the present study, we assessed metrezoate-labeled gallium transmission in burkett lymphatic cells. materials and methods: human burkitt lymphatic cells were grown in cultur...

Electropolymerization of novel gallium Schiff-base complexes results in conducting metallopolymers containing either coordinatively saturated or unsaturated gallium metal centers. Depending on the chemical coordination of the metal centers, the embedded metal ions can act as seed points for the direct growth of size-controlled gallium sulfide nanoparticles in a conducting polymer, yielding a hy...

The structurally well-defined intermetallic compounds PdGa and Pd3Ga7 constitute suitable catalysts for the selective hydrogenation of acetylene. The surface properties of PdGa and Pd3Ga7 were characterized by X-ray photoelectron spectroscopy, ion scattering spectroscopy and CO chemisorption. Catalytic activity, selectivity and long-term stability of PdGa and Pd3Ga7 were investigated under diff...

Glucan particles (GPs) are hollow, porous 3-5 μm microspheres derived from the cell walls of Baker's yeast (Saccharomyces cerevisiae). The 1,3-β-glucan outer shell provides for receptor-mediated uptake by phagocytic cells expressing β-glucan receptors. GPs have been used for macrophage-targeted delivery of a wide range of payloads (DNA, siRNA, protein, small molecules, and nanoparticles) encaps...

Combination chemotherapy forms the backbone of cancer treatment. There is a need for new drug combinations for the treatment of mantle cell lymphoma (MCL). Herein, we show that gallium maltolate, a novel gallium compound, synergizes with bortezomib, a proteasome inhibitor, to induce cell death in MCL Granta cells. Cells exposed to either agent displayed caspase-3 activation, a loss of mitochond...

The reasons why aminoglycosides are bactericidal have not been not fully elucidated, and evidence indicates that the cidal effects are at least partly dependent on iron. We demonstrate that availability of iron markedly affects the susceptibility of the facultative intracellular bacterium Francisella tularensis strain SCHU S4 to the aminoglycoside gentamicin. Specifically, the intracellular dep...

The melting point of gallium (29.7646 °C) is a defining thermometric fixed point of the International Temperature Scale of 1990 (ITS-90). Realization of this melting point is performed using a fixedpoint cell containing high-purity (≥99.999 99 wt. % pure) gallium. A 30 kg single lot of gallium (99.999 9956 wt. % pure) constituting Standard Reference Material (SRM) 1751 was evaluated, and certif...
