A theoretical study was performed to evaluate the defersirox potency to chelate aluminum (Al) and gallium (Ga) as the toxic metals in biological systems. Deferasirox as an important class of chelators, which binds to the metallic center with the ratio of 1:2, is used to remove the toxic metals in the case of iron overload disease. The effects of water and DMSO as the solvent on the electronic n...

Gallium-67 citrate is known to localize within inflammatory sites. Gallium-67 scanning is used for the evaluation of lung inflammation (i.e. alveolitis) during interstitial lung diseases. We investigated 27 patients with cryptogenetic fibrosing alveolitis (n = 17) and hypersensitivity pneumonitis (n = 10) using gallium-67 lung scanning and lung function tests (forced vital capacity, diffusing c...

The novel antimicrobial gallium is a nonredox iron III analogue with bacteriostatic and bactericidal properties, effective for the treatment of Pseudomonas aeruginosa in vitro and in vivo in mouse and rabbit infection models. It interferes with iron metabolism, transport, and presumably its homeostasis. As gallium exerts its antimicrobial effects by competing with iron, we hypothesized that it ...

Synthetic zeolites were dissolved in nitric acid, and the resulting solution used as a coprecipitant for the preconcentration of trace amounts of gallium in water samples prior to determination by electrothermal atomic absorption spectrometry (ETAAS). The gallium preconcentration conditions and the ETAAS measurement conditions were optimized. Gallium was quantitatively concentrated with the zeo...

A novel XRF sample preparation method was investigated to quantify the concentration of gallium in plutonium metal and minimize the possibility of contaminating the instrument with radioactive material. To prepare homogenous specimens and to add an internal standard, the plutonium must first be dissolved. The currently established method then entails removing the plutonium by chromatography and...

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...

Metallic gallium dissolves slowly in dilute mineral acids but rapidly in aqua regia and concentrated sodium hydroxide. In its compounds, the valency is +3. Its oxygen compounds resemble those of aluminum in that there are highand lowtemperature forms of Ga2O3 and two hydroxides, Ga(OH)3 and GaO·OH. Substances which lower the hydrogen ion concentration throw down a white gelatinous precipitate f...

The device library in the standard circuit simulator (SPICE) lacks a gallium nitride based high-electron-mobility-transistor (GaN-HEMT) model, required for design and verification of power-electronic circuits. This paper shows that GaN-HEMTs can be modeled by selected equations from MOSFET LEVEL 3 model SPICE. A method is proposed extraction SPICE parameters these equations. parameter-extractio...
