Comparison of some physicochemical and pharmacokinetical parameters of Tc-99m-PAH, Tc-99m-MAG(3) and I-131-OIH
(Journal of Radioanalytical and Nuclear Chemistry, 2002)
The purpose of this study was to compare some physicochemical characteristics as well as pharmacokinetic behavior of Tc-99m-PAH as a novel renal agent, with Tc-99m-MAG(3) and (OIH)-O-131. Tc-99m-PAH was prepared from ...
The modulatory effect of estradiol benzoate on superoxide dismutase activity in the developing rat brain
(Brazilian Journal of Medical and Biological Research, 2003)
The sensitivity of copper,zinc (CuZn)- and manganese (Mn)-superoxide dismutase (SOD) to exogenous estradiol benzoate (EB) was investigated in Wistar rats during postnatal brain development. Enzyme activities were measured ...
Apoptotic versus genotoxic potential of antimtumor agents: a concept of duality in unity
(Medical Hypotheses, 2003)
Recent advances in anti-tumor therapy have raised a problem of secondary tumors and tumor resistance. Secondary tumors induced by chemotherapeutic agents as a consequence of primary therapy have poor prognostic outcome. ...
A mean-count-rate meter with adaptive digital signal smoothing
(Instruments and Experimental Techniques, 2006)
Two algorithms for adapting exposures to pulse-arrival rates are briefly described, and examples of their use in radiometers are given.
The effects of microalloying with silicon and germanium on microstructure and hardness of a commercial aluminum alloy
(Journal of the Serbian Chemical Society, 2003)
The effect of small additions of Si and Ge on the microstructure and hardness was investigated during aging of a commercial 2219 aluminum alloy It was found that for the same level of microalloying in alloy 2219SG (containing ...
Densification and crystallization behaviour of colloidal cordierite-type gels
(Journal of the Serbian Chemical Society, 2001)
Three cordierite-type gels were prepared from an aqueous solution of Mg(NO3)(2). a boehmite sol and silica sols of very small particle sizes. The effect of varying the silica particle size on the crystallization and ...
Unidirectional stripping extraction from a cyclotron which accelerates light as well as heavy ions
(Physical Review Special Topics - Accelerators and Beams, 2003)
The VINCY Cyclotron (VINca CYclotron) is a multipurpose machine intended to accelerate light as well as heavy ions. To extract heavy ions with low energy and light ions an extraction system with stripping foil is used. ...
IR laser-induced changes to L-adrenaline-D-hydrogentartrate incorporated in KBr matrices
(Laser Chemistry, 2002)
Changes in the pharmaceutical L-adrenaline-D-hydrogentartrate, incorporated in KBr matrices, induced by a pulsed carbon-dioxide Transversely Excited Atmospheric (TEA) laser, were observed. Modifications of the sample were ...
Effect of curing time on the fraction of Cs-137 from cement matrix
(Annals of Nuclear Energy, 2003)
To assess the safety of disposal of radioactive waste material in concrete, curing conditions and time of leaching radionuclides Cs-137 have been studied. Leaching tests in concrete were carried out in accordance with a ...
Synthesis and settings behavior of alpha-TCP from calcium deficient hyroxyapatite obtained by hydrothermal method
(Journal of Optoelectronics and Advanced Materials, 2007)
The aim of this work is the investigation of alpha-tricalcium-phosphate (alpha-TCP) formation from calcium-deficient hydroxyapatite (CDHAP), synthesized by hydrothermal method from CaCl2, EDTA, NaH2PO4 center dot 2H(2)O ...
