The uptake of strontium by calcium phosphate phase formed at an elevated pH
(Journal of Radioanalytical and Nuclear Chemistry, 1996)
The sorption of radioactive strontium by poorly crystalline hydroxyapatite (HA) obtained by the transformation of amorphous calcium phosphate (ACP) at initial pH 10.8, was investigated, Morphological analysis, performed ...
Modified pyrophosphate-Tc-99m kit for application in nuclear cardiology
(Journal of Radioanalytical and Nuclear Chemistry, 1998)
A modified Tc-99m(Sn)-pyrophosphate (PyP) kit for the application in nuclear cardiology (radioventriculography, angiocardiography, scintigraphy of blood pool) was developed. Each vial contains 12 mg PyP (Na4P2O7), 4 mg ...
Elucidation of the character of radionuclide concentration changes in the near ground layer of air
(Journal of Radioanalytical and Nuclear Chemistry, 1998)
The Fokker Planck equation was used to analyze the probability of the appearance of radionuclide impulses of any type. Distribution functions for the stationary state and conditions when different factors influence the ...
Stability of fractionated technetium-cold pyrophosphate solution
(Journal of Radioanalytical and Nuclear Chemistry, 1998)
The cold solution of a pyrophosphate kit was prepared and dispensed into 2-ml fractions which were stored at -20 degrees C for one week. The solution was prepared by using two protection methods. The first was nitrogen ...
New Tc-99m-diiodine substituted IDA derivative (DIIODIDA) for hepatobiliary imaging
(Journal of Radioanalytical and Nuclear Chemistry, 1999)
A new diiodine substituted LDA derivative, 2,4-diiodine-6-methyl IDA (DIIODIDA) was synthesized and labeled with Tc-99m. It was established that Tc-99m-DIIODIDA had high radiochemical purity. Biodistribution and influence ...
Technetium-99m labeling of hippuric and p-amino-hippuric acid in the presence of DTPA: Biological and pharmacokinetic evaluation and comparison with Tc-99m-DTPA
(Journal of Radioanalytical and Nuclear Chemistry, 1999)
Tc-99m-Hipp as a modified Tc-99m-DTpA, and Tc-99m-PAH as a new renal agent are developed. Each veal of lyophilised kit contain hippuric (Hipp) or p-aminohippuric acid (PAH), diethyltriaminepentaacetic acid as calciumtrisodium ...
Sorption of hypoiodous acid on activated carbon
(Journal of Radioanalytical and Nuclear Chemistry, 1996)
In spite of good adsorption characteristics of activated carbon for molecular iodine, from water solution, problems arising due to complexity of chemistry of iodine and hydrolysis as well as influences of other relevant ...
Development of RAST assay for determination of anti-Populus canadensis IgE antibodies
(Journal of Radioanalytical and Nuclear Chemistry, 1996)
One of the frequent causes of pollen allergy in our region (Serbia, Yugoslavia) is the pollen of poplar (Populus canadensis). The aim of this study was to form RAST for the determination of specific anti-Populus canadensis ...
Ion-exchange separation of uranium, thorium and plutonium isotopes from environmental samples
(Journal of Radioanalytical and Nuclear Chemistry, 1996)
Radioisotopes of uranium, thorium and plutonium in water, soil and fertilizer samples, have been chemically separated and determined by alpha-spectrometry method. Radiochemical Procedure involving ion-exchange, enabled to ...
Radiopharmaceutical complexes of technetium and tin: Physicochemical and biochemical research
(Journal of Radioanalytical and Nuclear Chemistry, 1999)
The list of the developed Tc-99m-kits in our research center is given, while the whole research work as a basis of Tc-99m scanning agents production is described. Research involved physico-chemical studies of both types ...
