AB  - The effects of Zn-doping on the dielectric behavior and electrical properties of bulk alpha-Fe2O3 have been studied. X-ray diffraction analysis revealed the presence of two phases in all samples: hematite and spinel ZnFe2O4, with the amount of spinel phase increasing with increasing Zn content. Scanning electron microscopy analysis combined with energy dispersive X-ray spectroscopy showed that the Zn-bearing phase occurred in the form of individual spinel ZnFe2O4 grains in a hematite matrix. DC conductivity was measured in the temperature range 25-225°C (298-498 K). Impedance spectroscopy measurements in the same temperature range were carried out in the frequency range 100Hz to 10 MHz. Increase in the Zn content resulted in increased electrical conductivity and higher values of the dielectric constant. The resistance and capacitance of grains and grain boundaries were analyzed by modeling the experimental results using an equivalent circuit.

AB  - In radionuclide therapy, the importance of 90Y as a beta-emitting radionuclide is increasing rapidly. The properties of the 90Y-labeled antimony trisulfide colloid (Sb2S3) were compared with the 99mTc-labeled one. Labeling efficiencies reached >96% and >97% for 90Y- and 99mTc-labeled colloids respectively. Both preparations were stable for 72 h in saline and 1% albumin solution. Filtration analysis showed that more than 94% of total 90Y radioactivity is associated with the colloidal particles smaller than 20 nm, while more than 90% of 99mTc radioactivity is associated with the particles retained on the filter with a 20 nm pore size. 90Y-labeled colloids showed high labeling efficiency, stability and potency for clinical use.

AB  - 99mTc-MIBI is a promising radiopharmaceutical for myocardial perfusion imaging agent, but it has also shown good results in identifying several types of tumors, such as breast, lung and thyroid cancers. It is a lipophilic, cationic technetium (1) complex. In this paper a complete study on the synthesis of 2-metohy-isobutyl-isonitrile (MIBI) as well as a formulation of a lyophilized kit for labeling with 99mTc is presented. Investigation on effective factors as well as finding out the optimum parameters to obtain the highest labelling efficiency and radiochemical purity of 99mTc-MIBI complex were performed. The radiochemical purity of the labelled preparation was high (>95%). Biodistribution study performed in health male Wistar rats showed satisfactory biokinetics results. 99mTc-MIBI was accumulated in sufficient amount into the hearth tissue for myocardial perfusion imaging. MIBI in kit formulation was found to be stable and also safe for administration.

AB  - Radiolabelling of antibodies depends on a number of factors including the chemical characteristics of the nuclide and the techniques employed for its incorporation into protein. For preliminary research we used model system and investigate the influence of different factors affecting labelling. Obtained results were successfully used for further radiolabelling of antibodies with different trivalent metals.
