The growth inhibitory effects of gallium on a murine and human B-cell line were studied using two different serum-free culture systems: (a) ferric citrate medium containing 500 microM iron and (b) transferrin medium containing 5 micrograms/ml of iron-saturated transferrin (0.125 microM iron). For the human cell line in ferric citrate medium, 50% growth inhibition achieved in the presence of tra...

Z. Naturforsch. 56 b, 458^462 (2001); received April 4, 2001 Gallium(III) and Gallium(II) Amides, Gallium Amino Complexes, Gallium Coordination The reaction of /V,/V-di('butyl)-ethane1,2-diamine with NaH followed by anhydrous GaCl3 (molar ratios 1:2 :1) gives mainly an insoluble bis(diamido)gallium chloride together with a low yield (28%) of a soluble monocyclic dichlorogallium-[2-('butylamino)...

the solvent extraction of gallium from a concentrated jajarm bayer process liquor containing 164.90 g/l of na2o, 86.70 g/l of al2o3 and 106.02 ppm of gallium was investigated using 10 vol.% kelex100, a 7-alkyl substituted-8 hydroxyquinoline as an extractant, 10 vol.% etanol as a modifier and kerosene as a diluent. at (vo :va = 1.0:1.0) organic to aqueous phase ratio and at room temperature, 93....

Gallium maltolate, tris(3-hydroxy-2-methyl-4H-pyran-4-onato)gallium (GaM), is an orally active gallium compound for therapeutic use. It is moderately soluble in water (10.7 +/- 0.9 mg/mL at 25 composite functionC) with an octanol partition coefficient of 0.41+/-0.08. The molecule is electrically neutral in aqueous solution at neutral pH; a dilute aqueous solution (2.5 x10-(-5) M) showed little ...

*Author for correspondence:rajan. [email protected] Aims: Increased 18F-flurodeoxyglucose uptake within active brown adipose tissue (BAT) on an 18F-flurodeoxyglucose PET/CT study is a known pitfall that has been well described in the literature. We have noted a similar phenomenon occurring in gallium-67 studies performed on neonates, which introduces an undesirable element of complexity when ev...

When cultured in a defined citrate medium supplemented with 1 mM gallium (III) Pseudomonas fluorescens ATCC 13525 experienced a lag phase of 40 h with no apparent diminution in cellular yield. Following initial uptake of the metal-ligand complex, gallium was secreted in the spent fluid. This lag phase was abolished either by inoculating the medium with gallium adapted cells or by inclusion of i...

introduction: despite widespread use of 67gallium for lymphoma evaluation, timing of imaging after injection is a matter of controversy and to the extent of our knowledge no direct comparison has been made between early and delayed gallium images. we aimed to compare 24 and 48 hours post injection planar gallium imaging for evaluation of lymphoma recurrence. methods: 255 patients suspicious of...

gallium extraction from jajarm bayer process liquor (jajarm, iran) was investigated using microemulsions. also the behavior of aluminum was studied as an impurity. kelex100 (4-ethyl, 1-methyl, 7-octyl, 8-hydroxyquinoleine), iso-decanol and n-butanol, and kerosene were used as the surfactant, co-surfactant, and oil phase, respectively. ternary phase diagrams were produced using various co-surfac...

UNLABELLED Accurate staging of Hodgkin's disease (HD) and non-Hodgkin's lymphoma (NHL) is important for treatment management. In this study, the utility of 2-[18F]fluoro-2-deoxy-D-glucose (FDG) whole-body PET was evaluated as an imaging modality for initial staging or restaging of 7 HD and 11 NHL patients. METHODS Whole-body PET-based staging results were compared to the patient's clinical st...
