BACKGROUND In order to increase understanding of how infused cells work, it becomes important to track their initial movement, localization, and engraftment efficiency following transplantation. However, the available in vivo cell tracking techniques are suboptimal. The study objective was to determine the biodistribution of intravenously administered Indium-111 (In-111) oxine labeled human umb...

UNLABELLED Imaging of osteomyelitis and soft-tissue infections can be problematic with currently available agents; bone scans are often false-positive. Indium-111-oxine and 99mTc-HMPAO white blood cell (WBC) scans require ex vivo handling of blood with potential exposure to infectious agents, and 99mTc-antigranulocyte (IgG1) antibodies need 24 hr for final diagnosis. METHODS We investigated t...

An extensive literature has developed in recent years in the field of chelate compounds with special reference to their antimicrobial properties. Thus, for example, the copper chelate of oxine (8-hydroxyquinoline) has been the subject of numerous investigations (Hollingshead, 1956). Thiosemicarbazones (TSC), which are compounds capable of forming chelates, have been investigated by Domagk (1950...

The gravimetric analysis of antimony(III) with oxine (8-quinolinol, Hox) was studied. The amount of antimony left in filtrate and washing solutions was corrected with the results of atomic absorption spectrometry. The weighing form, which had not been conclusive before the present study, was determined to be SbO(ox)(Hox)2. The result (purity of antimony(II) oxide: 99.84 +/- 0.05% (m/m)) of the ...

background: gallium-66 (t1/2= 9.49 h) is an interesting radionuclide that has potential for positron emission tomography (pet) imaging of biological processes in intermediate to slow target tissue uptake. oxine has been labeled with this radioisotope in the form of [66ga]gallium chloride for its possible diagnostic properties. materials and methods: 66ga was produced in the 30 mev cyclotron (cy...

Several studies have been made on the bacteriostatic and fungicidal properties of oxine (8-hydroxyquinoline) and other chelating agents, and it has been suggested that they might act, in part at least, by depriving cells of essential trace metals (Albert, 1951; Martell & Calvin, 1952). In an attempt to determine the trace element requirements of mammalian spermatozoa, White (1955) investigated ...

UNLABELLED Radionuclide therapy remains a promising arsenal against cancer. However, low tumor uptake, high radiation dose to normal organs, and subsequent adverse effects are challenging problems. This study assessed the therapeutic significance of lipid-soluble compounds of (111)In, which passively diffuse through the cell membrane, bind to cytoplasmic components, and remain cell bound until ...

After various earlier attempts with different radiotracers 51chromium and finally ^IndiumoKİne became the tracers of choice for the radiolabeling of human platelets and the subsequent monitoring of in vivo kinetics. Data on clinical application of platelet survival in atherosclerotic vascular disease and a variety of risk factors are presented. Furthermore, a new approach to use nonradioactive ...
