Gallium 67 citrate was evaluated with conventional scanning and emission computed tomography (CT) scanning as a method of pretreatment staging of the intrathoracic, especially mediastinal, spread of lung cancer. Of 31 patients with tumours of various histological types, the isotope was concentrated in the primary lesion in all but one. In 10 out of 12 patients who underwent surgical exploration...

Introduction: The increasing sophistication of the industries requiring optical thin films from unconventional materials calls for alternative fabrication methods. Thin film for use in broadband and narrowband filtering applications, including dense wavelength division multiplexing (DWDM), optical amplification, switching, modulation of light signals, grating based devices, infrared light trans...

A structural transformation induced by optical impulse excitation of only a few mJ/cm fluence affecting the nanoscale surface melt layer of gallium at a ZnSe–gallium interface leads to a fast, substantial and fully reversible change in reflectivity of up to 50%. Recovery occurs within a few ls after excitation is withdrawn and less than 1 ls at temperatures more than 4 K below gallium s melting...

Nanobacteria, 100-fold smaller than common bacteria, have been purported to exist in urine, and by precipitating calcium and other minerals into carbonate apatite around themselves, induce the formation of surrounding kidney stones. Nanobacteria-like structures have also been shown in blood, within arteries, aortic aneurysms, and cardiac valves. Gallium has antibiotic properties to iron-depende...

The electrical conductivity of solid and molten Li2S04 —Ag,S0 4 has been measured for different concentration values. Density measurements of molten Li2S04 , Ag2S04 and equimolar (Li, Ag) 2S0 4 show that the system can be considered ideal. The equivalent conductivity of molten (Li, Ag) 2S0 4 can be calculated from the conductivities of the pure salts by assuming that the cations are moving in g...

Tuberculosis peritonitis is a rare manifestation of extrapulmonary tuberculosis. The results of gallium-67 scintigraphy of three patients with tuberculosis peritonitis were reviewed to assess its usefulness in the diagnosis of this condition. Tuberculosis peritonitis was associated with diffuse or focal abdominal localization and decreased hepatic accumulation of gallium-67. These gallium-67 sc...

  Introduction: Although PET scanning using F-18[FDG] is considered the superior radiotracer for tumnor imaging, Gallium-67 is still in use for some malignancies such as lymphoma and hepatoma. One of the strategies to improve the diagnostic accuracy of Gallium is to perform SPECT which is reported to be more sensitive compared to planar imaging. In this study we compa...

purpose: to describe a patient with eyelid sarcoidosis. case report: a 54 year-old patient was referred for an eyelid mass from 6 months ago.excisional biopsy showed inflammatory granuloma with tuton gaint cells. chest radiograph demonstrated bilateral hilar adenopathy, increased absorption on gallium scan was noted and bronchoalveolar lavage confirmed a diagnosis of sarcoidosis. treatment with...

the hybrid molten/solid in2o3 - 30-48 wt.% bi2o3 oxide materials were studied with respect to their transport properties. the conductivities, oxygen ion transport numbers and oxygen permeation fluxes have been measured by using the four-probe dc, volumetric measurements of the faradaic efficiency and gas flow techniques, respectively. we show that the oxygen permeability of the hybrid molten/so...
