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...

A simple and rapid vortex assisted ionic liquid based liquid-liquid microextraction technique (VALLME) was proposed for preconcentration of trace levels of cadmium. According to this method, the extraction solvent was dispersed into the aqueous samples by the assistance of vortex agitator. Cadmium preconcentration was mediated by chelation with the 8-hydroxyquinoline (oxine) reagent and an IL, ...

The Pb(II) atom in the title compound, [Pb(C(10)H(8)NO)(2)], is chelated by two oxine (2-methyl-quinolin-8-olate) anions in a Ψ-trigonal-bipyramidal geometry; the N atoms occupy the axial sites. The mol-ecule lies about a twofold rotation axis.

BACKGROUND Clinical trials indicate a beneficial effect of intracoronary infusion of progenitor cells on myocardial function in patients with ischemic heart disease. The extent and potential determinants of proangiogenic progenitor cell homing into the damaged myocardium after intracoronary infusion and the underlying mechanisms are still unknown. METHOD AND RESULTS Circulating proangiogenic ...

An incidental finding of absent splenic uptake of autologous, indium-111-oxine-labeled leukocytes in an immunosuppressed renal transplant recipient was documented to be associated with functional asplenia based on absence of technetium-99m-sulfur colloid clearance by a morphologically normal spleen. The patient had recently suffered an episode of disseminated varicella infection that might have...

Thrombocytopenia is a common occurrence (20%) in sick neonates. but the causes have not been well studied. In this report we demonstrate that thrombocytopenia in the neonate is characterized by increased platelet destruction as shown by shortened homologous “In-oxine-labeled platelet life spans. Thirty-one prospectively studied thrombocytopenic neonates were investigated by measuring the “In-la...

introduction: the field of stem cell biology and regenerative medicine is rapidly moving toward translation to clinical practice. stem cell therapy seems to be a new treatment option for some diseases. so, tracking the distribution of stem cells is crucial to their therapeutic use. based on this fact we labeled human mesenchymal stem cells (mscs) with 111in- oxine for the first time in our coun...
