AB  - The content of combustible elements in solid mineral fuels (carbon, hydrogen, etc.) are very important, since they most directly affect the heat value. It should be noted that the fuel heat value depends on many other constituents, such as ash and moisture. In this paper, special attention has been paid to carbon content. In solid mineral fuels, carbon is found alone or bound in the form of various compounds. One of them is mineral carbonate compounds bound as carbonate carbon, which originates from absorbed CO2 from atmosphere. Determination of carbonate carbon content of solid mineral fuels was performed by standard gravimetric method (according to ISO 925: 2019), and newly developed instrumental method, using thermogravimetric analyzer LECO TGA 701. Comparison of obtained experimental results was done. Four types of coal, Kolubara lignite, Kostolac lignite, brown coal, and control coal sample were included in experimental analysis. In addition, moisture in the samples was also determined using analytical method and inspected using LECO TGA 701 thermogravimetric analyzer, as well as total carbon content using the LECO CHN 628 elemental analyzer. An analysis and comparison of the obtained results was performed, and comments and conclusions are presented. The experiments were done in the department for fuel characterization, Laboratory for Thermal Engineering and Energy, Institute of Nuclear Sciences Vinca.

AB  - Two new Schiff base cobalt(III) ([Co(LH)Cl2], 1) and nickel(II) ([Ni(LH)ClO4], 2) complexes with a diimine-dioxime ligand, (4,9-diaza-3,10-diethyl-3,9-dodecadiene-2,11-dione bis oxime (LH2)), were synthesized and characterized. The compounds were obtained in MeOH from corresponding metal salts and LH2 in molar ratio 1:1 and further characterized by mass spectrometry, IR spectroscopy, electrochemistry, and elemental analysis. Previously reported copper(II) analog ([Cu2(LH)2]·(ClO4)2, 3) was joined to 1 and 2, and the three metal analogs, 1–3, were further investigated in terms of their electrochemical behavior. Binding studies of the complexes with deoxyribonucleic acid (DNA) and human serum albumin (HSA) were carried out using both spectrophotometric and electrochemical methods. All three complexes exhibit binding affinity towards the DNA chain through intercalative interactions. The binding reaction with HSA showed for 1 and 3 decrease in the peak current obtained in the case of complexes before the addition of HSA, while the Ni complex–HSA possesses the same electroactivity as starting complex. The cytotoxicity of LH2 as well as its metal complexes, and cisplatin were evaluated on CT-26 mouse colon carcinoma and human LS174T cancer cell lines employing MTT assay. The copper(II) complex exhibited very promising anticancer activity compared with cisplatin.

AB  - Different phosphates and phosphonates have shown excellent coating ability toward magnetic nanoparticles, improving their stability and biocompatibility which enables their biomedical application. The magnetic hyperthermia efficiency of phosphates (IDP and IHP) and phosphonates (MDP and HEDP) coated Fe3O4 magnetic nanoparticles (MNPs) were evaluated in an alternating magnetic field. For a deeper understanding of hyperthermia, the behavior of investigated MNPs in the non-alternating magnetic field was monitored by measuring the transparency of the sample. To investigate their theranostic potential coated Fe3O4-MNPs were radiolabeled with radionuclide 177Lu. Phosphate coated MNPs were radiolabeled in high radiolabeling yield (> 99%) while phosphonate coated MNPs reached maximum radiolabeling yield of 78%. Regardless lower radiolabeling yield both radiolabeled phosphonate MNPs may be further purified reaching radiochemical purity of more than 95%. In vitro stabile radiolabeled nanoparticles in saline and HSA were obtained. The high heating ability of phosphates and phosphonates coated MNPs as sine qua non for efficient in vivo hyperthermia treatment and satisfactory radiolabeling yield justifies their further research in order to develop new theranostic agents. © 2021, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.

AB  - Purpose Recent studies with doxycycline as adjuvant therapy to conventional chemotherapy have shown promising results in cancer therapy. The current study aimed to examine the capability of 177Lu-labeled tetracycline ligand, doxycycline hyclate, to use as an anticancer agent.Materials and methods Doxycycline was radiolabeled with beta-emitting radioisotope 177Lu. Complex formation and its interaction with DNA were investigated electrochemically. Binding of 177Lu-doxycycline to CT 26 cell line was done. Biodistribution of 177Lu-doxycycline was examined in healthy Wistar rats and CT26 colon carcinoma tumor-bearing mice by i.v. and i.p. administration, respectively.Results Doxycycline hyclate was successfully radiolabeled with 177Lu in high radiolabeling yield (>99%). The radiolabeled complex was stable in vitro in saline and human serum over 72 h. Non-radioactive Lu-doxycycline complex formation was demonstrated electrochemically as well. Intercalative interactions of the doxycycline and Lu-doxycycline with DNA were proved using simultaneously spectrophotometric and electrochemical methods. The binding of the radiolabeled complex with plasma proteins was 4.0 ± 0.4%. The partition coefficient showed the lipophilic nature of the complex similar to the free ligand. The binding curve demonstrates binding from 0.1 nM concentrations of 177Lu-doxycycline, with half-binding estimated ∼100 nM. Biodistribution studies of 177Lu-doxycycline in CT26 colon tumor-bearing mice showed a satisfactory accumulation rate in the tumor (2.88 ± 0.85% ID/g) 3 h after intraperitoneal injection. Both the hepatobiliary system and the urinary system were prominent as excretory routes of the radiolabeled complex.Conclusion Considering obtained results, 177Lu-doxycycline complex, due to its excellent electrochemical and biological characteristics, with emphasis on the binding ability to DNA via intercalative interaction as well as significant accumulation in the tumor, is suitable for further in vivo studies to investigate its potential use in cancer treatment.

AB  - This work presents advanced electrochemical platform based on screen printed diamond electrode (SPDE) system for the single drop “point-of-care” testing. Proposed approach was applied for the quantification of doxorubicin hydrochloride (DOX) in biological fluids and pharmaceutical product. Using a single drop (~30 μL) of the tested solution at the electrode surface, DOX showed high electroactivity over a wide range of pHs. In these conditions, single oval shaped, well-defined and pH dependent oxidation peak was observed in the potential range from 0.5 V to 1.3 V. In the reverse scan, two cathodic peaks, were noted – around 0.3 V and – 0.5 V. Similarly, first reduction peak was pH dependent, while second one was independent in the studied range. Experimental conditions for DOX quantification were optimized and natures of the electrode reactions were investigated. Working linear range obtained for DOX detection was from 0.1 to 2.5 μM. Diffusion controlled electrode reaction reveal long life time of the proposed electrode as well high potential for practical application. Developed procedure was successfully applied for the DOX analysis in biological fluids – urine and pharmaceutical formulation. Obtained results clearly indicated that given procedure can be easily implemented for pharmaceutical control and medical analysis, in both, laboratory and field conditions. © 2021 Elsevier B.V.

In the reverse scan, two cathodic peaks, were noted – around 0.3 V and – 0.5 V. Similarly, first reduction peak was pH dependent, while second one was independent in the studied range. Experimental conditions for DOX quantification were optimized and natures of the electrode reactions were investigated. Working linear range obtained for DOX detection was from 0.1 to 2.5 μM. Diffusion controlled electrode reaction reveal long life time of the proposed electrode as well high potential for practical application. Developed procedure was successfully applied for the DOX analysis in biological fluids – urine and pharmaceutical formulation. Obtained results clearly indicated that given procedure can be easily implemented for pharmaceutical control and medical analysis, in both, laboratory and field conditions. © 2021 Elsevier B.V.",

AB  - Liposomes are promising drug's delivery systems due to decreased toxicity of the liposome-encapsulated drug, but wider clinical application requires their more efficient tumor targeting with uptake, controlled drug release and higher shelf life. The unique metabolic characteristics of cancer cells based on higher demand for energy and therefore increased glucose utilization were exploited in the design of glucose modified liposomes (GML) with the aim to provide increased tumor targeting via glucose transporters and increased ability of drug delivery into tumor cells. Tumor accumulating potential of GML and non-glucose liposomes (NGL) were investigated on CT26 and LS174T tumor-bearing mice by simple and reliable radiotracer method using 177Lu as radioactive marker. Both liposomes, GML and NGL were radiolabeled in high radiolabeling yield, showing high in vitro stability in biological media, as the main prerequisite for the biodistribution studies. Tumors displayed significantly better accumulation of 177Lu-GML with the maximum uptake 6 h post-injection (5.8 ± 0.2%/g in LS174T tumor and 5.1 ± 0.5%/g in CT26 tumor), compared to negligible uptake of 177Lu-NGL (0.6 ± 0.1%/g in LS174T tumor and 0.9 ± 0.2%/g in CT26 tumor). Results of comparative biodistribution studies of 177Lu-NGL and 177Lu-GML indicate that increased accumulation of GML is enabled by glucose transporters and subsequent endocytosis, resulting in their prolonged retention in tumor tissues (up to 72 h). Direct radiolabeling of liposomes with 177Lu may be used not only for biodistribution studies using radiotracking, but also for cancer treatment. © 2021 Elsevier B.V.

AB  - Enhanced degradation of organic dye was achieved using two different kinds of waste materials: waste tire granules and spent sealed radioactive sources. Waste tire granules were used as raw material for the production of waste tire char (WTC), which was further utilized as an adsorbent matrix for synergetic adsorption/irradiation degradation of organic dye. The spent radioactive sources were radiographic sealed sources that originate from the industry which generate the high energy radiation. Methylene Blue (MB) was used as an organic model compound. Synthesized WTC has turbostratic structure, irregular shaped particles and developed mesoporous surface. Complete degradation of 0.02 dm3 of 100 mg dm−3 MB solution, having WTC dose of 1.25 g dm−3, was achieved with delivered doze of only 60 Gy. The applied doses were 100 times smaller than those presented in the literature. Degradation pathway was determined: OH radicals that originate from radiolysis of water and from the surface of WTC played the crucial role in the radiocatalytic degradation of MB. Breakage of the aromatic ring of MB appeared by the scission of the double C‒S+˭C bond as a result of the attack of OH species on adsorbed and electronically reorganized MB molecule. © 2020 Elsevier B.V.

AB  - Micro–sized multivesicular liposomes were prepared, radiolabeled with 177Lu, and tested in vitro and in vivo to evaluate the potential of 177Lu–labeled micro liposomes in radiosynoviorthesis (RSO) therapy. A standard reverse–phase procedure of liposome preparation with a lipid mixture of DPPC: CHOL (80:20%) was used for the synthesis. TEM and fluorescence microscopy imaging were performed to determine the size, shape, and structure of the prepared liposomes. Both measurements are in good agreement while TEM micrographs additionally indicate to a large multivesicular inner structure of prepared liposomes. A simple and straightforward procedure was used for liposome radiolabeling with 177Lu, a well–known and commonly used radionuclide in radiotherapy with favorable properties, that can be exploited in RSO therapy. Radiolabeled 177Lu–liposomes were tested in vitro for stability and then injected into the knee joints of Wistar rats where liposome in vivo behavior was followed up to 30 days post injection. Results from both ex vivo biodistribution and in vivo imaging studies presented a high stability and retention (>94 %ID) of 177Lu–micro liposomes in the synovial liquid for the entire observation period. Leakage of free 177Lu or 177Lu–liposomes from the synovial fluid has not been detected, indicating to a possible application of 177Lu–liposomes in radiosynoviorthesis (RSO) therapy.

AB  - Small glucose-modified liposomes (GMLs) were loaded with magnetic Fe3O4 nanoparticles (MNPs) and fluorescein using a standard thin layer preparation procedure and a varying lipid/MNPs ratio. The liposomes were characterized with TEM and DLS measurements, and MNPs encapsulation rate was determined using ICP-OES. Prepared liposomes were stored at 5 °C for 30 days and subsequently exposed to an external magnetic field (20 mT) with varying exposure times (2‒20 min), at room temperature. The release of fluorescein from GMLs induced by the magnetic field exposures was quantified, showing a high release rate (25‒85%) depending on the concentration of MNPs in GMLs. EPR measurements were conducted during the liposomes storage period in order to provide semi-quantitative information of possible MNPs oxidation from Fe3O4 to Fe2O3 inside the liposomes, impacting MNPs magnetic properties. In contrast to the MNPs water dispersion, no significant change in the EPR signal of MNPs encapsulated inside GMLs was detected over the course of 30 days. The data presented in this study indicate that GMLs loaded with MNPs maintain a high stability for prolonged periods of time and that this delivery system may be used for magnetically assisted controlled drug release.

AB  - Combined radionuclide therapy with magnetic nanoparticles-mediated hyperthermia has been under research focus as a promising tumor therapy approach. The objective of this study was to investigate the potential of 131I-radiolabeled superparamagnetic iron oxide nanoparticles (SPIONs) prepared as the ~40 nm flower-shaped structures with excellent heating efficiency (specific absorption rate at H0 = 15.9 kA∙m−1 and resonant frequency of 252 kHz was 123.1 W∙g−1) for nano-brachytherapy of tumors. 131I-radiolabeled CC49 antibody attached to SPIONs via reactive groups of 3-aminopropyltriethoxysilane (APTES) provided specificity and long-lasting localized retention after their intratumoral application into LS174T human colon adenocarcinoma xenografts in NOD-SCID mice. The results demonstrate feasibility and effectiveness of magnetic hyperthermia (HT), radionuclide therapy (RT) and their combination (HT + RT) in treating cancer in xenograft models. Combined therapy approach induced a significant (p < 0.01) tumor growth suppression in comparison to untreated groups presented by the tumor volume inhibitory rate (TVIR): 54.38%, 68.77%, 73.00% for HT, RT and HT + RT, respectively in comparison to untreated group and 48.31%, 64,62% and 69,41%, respectively, for the SPIONs-only injected group. Histopathology analysis proved the necrosis and apoptosis in treated tumors without general toxicity. Obtained data support the idea that nano-brachytherapy combined with hyperthermia is a promising approach for effective cancer treatment.

The objective of this study was to investigate the potential of 131I-radiolabeled superparamagnetic iron oxide nanoparticles (SPIONs) prepared as the ~40 nm flower-shaped structures with excellent heating efficiency (specific absorption rate at H0 = 15.9 kA∙m−1 and resonant frequency of 252 kHz was 123.1 W∙g−1) for nano-brachytherapy of tumors. 131I-radiolabeled CC49 antibody attached to SPIONs via reactive groups of 3-aminopropyltriethoxysilane (APTES) provided specificity and long-lasting localized retention after their intratumoral application into LS174T human colon adenocarcinoma xenografts in NOD-SCID mice. The results demonstrate feasibility and effectiveness of magnetic hyperthermia (HT), radionuclide therapy (RT) and their combination (HT + RT) in treating cancer in xenograft models. Combined therapy approach induced a significant (p < 0.01) tumor growth suppression in comparison to untreated groups presented by the tumor volume inhibitory rate (TVIR): 54.38%, 68.77%, 73.00% for HT, RT and HT + RT, respectively in comparison to untreated group and 48.31%, 64,62% and 69,41%, respectively, for the SPIONs-only injected group. Histopathology analysis proved the necrosis and apoptosis in treated tumors without general toxicity. Obtained data support the idea that nano-brachytherapy combined with hyperthermia is a promising approach for effective cancer treatment.",

AB  - Novel theranostic nanoplatform is expected to integrate imaging for guiding and monitoring of the tumor therapy with great therapeutic efficacy and fewer side effects. Here we describe the preparation of a multifunctional 99mTc–bisphosphonate–coated magnetic nanoparticles (MNPs) based on Fe3O4 and coated with two hydrophilic bisphosphonate ligands, i.e., methylene diphosphonate (MDP) and 1–hydroxyethane-1,1- diphosphonate (HEDP). The presence of the bisphosphonates on the MNPs surface, enabled their biocompatibility, colloidal stability and successful binding of the radionuclide. The morphology, size, structure, surface charge and magnetic properties of obtained bisphosphonate–coated Fe3O4 MNPs were characterized by transmission electron microscopy, X–ray powder diffraction, dynamic light scattering, laser Doppler electrophoresis, Fourier transform infrared spectroscopy and vibrating sample magnetometer. The specific power absorption values for Fe3O4–MDP and Fe3O4–HEDP were 113 W/g and 141 W/g, respectively, indicated their heating ability under applied magnetic field. Coated MNPs were radiolabeled with 99mTc using stannous chloride as the reducing agent in a reproducible high yield (95% for Fe3O4–MDP and 97% for Fe3O4–HEDP MNPs) and were remained stable in saline and human serum for 24 h. Ex vivo biodistribution studies presented significant liver and spleen uptake in healthy Wistar rats after intravenous administration at all examined time points due to the colloidal nature of both 99mTc–MNPs. Results of scintigraphy studies are in accordance with ex vivo biodistribution studies, demonstrating high in vivo stability of radiolabeled MNPs and therefore results of both methods were proved as accurate information on the biodistribution profile of investigated MNPs. Overall, in vitro and in vivo stability as well as heating ability, indicate that biocompatible radiolabeled bisphosphonate magnetic nanoparticles exhibit promising potential as a theranostic nanoagent. © 2019 Elsevier B.V.

AB  - It was reported that novel O,O′-diethyl-(S, S)-ethylenediamine-N,N′-di-2-(3-cyclohexyl) propanoate dihydrochloride (DE-EDCP) displayed in vitro antiproliferative activity on several human and mouse cancer cell lines, which was comparable to that of the prototypical anticancer drug cisplatin. In order to reveal its toxicity profile, acute and repeated-dose toxicity studies were performed in Naval Medical Research Institute (NMRI) Han mice. The intravenous LD50 values of DE-EDCP were found to be 95.3 and 101.3 mg/kg body weight in female and male mice, respectively. In the subacute toxicity study, DE-EDCP was administered intravenously at the doses of 15, 25, and 40 mg/kg/day for a period of 28 days. There were no adverse effects on general condition, growth, feed and water consumption, and hematological parameters. There was a significant increase in urea and alanine aminotransferase in female mice and aspartate aminotransferase and alkaline phosphatase in both genders in 40 mg/kg/day dose-treated group. The histopathological changes confined to the liver and kidney, but in other organs were not found. Satellite group revealed that changes in the kidney and liver were less pronounced, suggesting their reversibility. Interactions with DNA could also be of importance for understanding DE-EDCP toxic side effects. Hyperchromic effect obtained with ultraviolet–visible, suggested electrostatic interactions between DE-EDCP and calf thymus DNA. The toxicity testing of DE-EDCP was conducted to predict human outcomes. © The Author(s) 2018.

AB  - Development of a complex based on iron oxide nanoparticles (IONPs) for diagnosis and dual magnetic hyperthermia/radionuclide cancer therapy accomplishing high yields of radiolabeling and great magnetic heat induction is still a challenge. We report here the synthesis of citric acid, poly(acrylic acid) (PAA) and poly(ethylene glycol) coated IONPs and their labeling with three radionuclides, namely, technetium (99mTc), yttrium (90Y), and lutetium (177Lu), aiming at potential use in cancer diagnosis and therapy. Polyol-synthesized IONPs are a flowerlike structure with 13.5 nm spherically shaped cores and 24.8 nm diameter. PAA-coated nanoparticles (PAA@IONP) showed the best characteristics such as easy radiolabeling with very high yields (&gt;97.5%) with all three radionuclides, and excellent in vitro stabilities with less than 10% of radionuclides detaching after 24 h. Heating ability of PAA@IONP in an alternating external magnetic field showed intrinsic loss power value of 7.3 nH m2/kg, which is one of higher reported values. Additionally, PAA@IONP itself presented no significant cytotoxicity to the CT-26 cancer cells, reaching IC50 at 60 μg/mL. However, under the external magnetic field, they show hyperthermia-mediated cells killing, which correlated with the magnetic field strength and time of exposure. Since PAA@IONP are easy to prepare, biocompatible, and with excellent magnetic heat induction, these nanoparticles radiolabeled with high-energy beta emitters 90Y and 177Lu have valuable potential as agent for dual magnetic hyperthermia/radionuclide therapy, while radiolabeled with 99mTc could be used in diagnostic imaging.

AB  - The adsorption properties of two zeolite types, faujasite (NaY, ZnY, CoY) and LTA-4A zeolite (NaA, ZnA, CoA), towards technetium were studied in batch static experiments. The Si/Al ratio, acidity, dealumination, chargebalance cations of zeolite, contact time and temperature determined the adsorption efficiency. The maximum removal efficiency of 98.8% and Kdvalue (2.06 × 10−4 cm3 g−1) was achieved using CoY (zeolite type Y). The kinetics of technetium adsorption followed the pseudo-second order model. The TcO2adsorption is mainly due to the hydrogen bonds between protons of the zeolitic structural OH groups (Bronsted acid center) and oxygen from the TcO2−.

AB  - Radiolabeled magnetic nanoparticles (MNPs) coated with hydrophilic phosphate ligands, i.e., imidodiphosphate (IDP) and inositol hexaphosphate (IHP), were developed as multifunctional agents to localize both radioactivity and magnetic energy at a tumor site. The coating of MNPs with phosphates made them biocompatible, increased their colloidal stability and allowed binding of the radionuclide Y-90 to the available functional groups on the surface of the MNPs. IDP and IHP have not hitherto been used for the coating of MNPs and the results of this study of the functionalized MNPs showed that the phosphate groups influenced the modification of the surface of MNPs. Characterization of the MNPs was performed using X-ray powder diffraction, transmission electron microscopy, Fourier transform infrared spectroscopy, dynamic light scattering and laser Doppler electrophoresis. The specific power absorption values obtained for MNPs (46.95-80.76 W g(-1)) in different physiological media indicated their possible application in hyperthermia treatment. Both types of coated MNPs were Y-90-labeled in a reproducible high yield ( GT 98%). In vitro studies of Y-90-MNPs in saline and human serum showed their high stability after 72 h. The biodistribution pattern of the MNPs after intravenous administration to healthy Wistar rats was followed by the radiotracer method, revealing that Y-90-Fe3O4-IDP and Y-90-Fe3O4-IHP MNPs were predominantly found in the liver (85.21% ID and 86.22% ID), followed by the spleen (9.23% ID and 8.82% ID) and the lungs (1.53% ID and 1.53% ID). The results of this comprehensive study showed that radiolabeled biocompatible phosphate magnetic complexes hold great promise for therapeutic uses combining magnetic hyperthermia and radiotherapy.

AB  - Two different types of magnetic nanoparticles (MNPs) were synthesized in order to compare their efficiency as radioactive vectors, Fe3O4-Naked (80 +/- 5 nm) and polyethylene glycol 600 diacid functionalized Fe3O4 (Fe3O4-PEG600) MNPs (46 +/- 0.6 nm). They were characterized based on the external morphology, size distribution, and colloidal and magnetic properties. The obtained specific power absorption value for Fe3O4-PEG600 MNPs was 200 W/g, indicated their potential in hyperthermia based cancer treatments. The labeling yield, in vitro stability and in vivo biodistribution profile of Y-90-MNPs were compared. Both types of MNPs were Y-90-labeled in reproducible high yield ( GT 97%). The stability of the obtained radioactive nanoparticles was evaluated in saline and human serum media in order to optimize the formulations for in vivo use. The biodistribution in Wistar rats showed different pharmacokinetic behaviors of nanoparticles: a large fraction of both injected MNPs ended in the liver (14.58%ID/g for Y-90-Fe3O4-Naked MNPs and 19.61%ID/g for Y-90-Fe3O4-PEG600 MNPs) whereas minor fractions attained in other organs. The main difference between the two types of MNPs was the higher accumulation of Y-90-Fe3O4-Naked MNPs in the lungs (12.14%ID/g vs. 2.00%ID/g for Y-90-Fe3O4-PEG600 MNPs) due to their in vivo agglomeration. The studied radiolabeled magnetic complexes such as Y-90-Fe3O4-PEG600 MNPs constitute a great promise for multiple diagnostic-therapeutic uses combining, for example, MRI-magnetic hyperthermia and regional radiotherapy.

AB  - (99)Technetium is one of the largest components of nuclear waste material. In aqueous solutions Tc-99 is present as the pertechnetate oxoanion, (TcO4-)-Tc-99, which is highly soluble and mobile in groundwater under oxidizing conditions, thus posing a major environmental concern. In this study, a series of organo-modified bentonite clay samples was tested as adsorbents for the removal of radioactive (TcO4-)-Tc-99 from aqueous solution at room temperature. The influence of the hexadecyl trimethylammonium (HDTMA)/bentonite ratio on the adsorption ability of the organobentonites was investigated. It was found that the adsorbent in which the exchangeable cations were only partially substituted with HDTMA showed very low affinity toward pertechnetate. On the other hand, the adsorbents in which the HDTMA loading exceeded the cation exchange capacity (CEC) value had high efficiency. The behavior of such adsorbents was best described by a Freundlich isotherm, while for the sample in which the HDTMA loading was equal to the CEC, the linear adsorption isotherm was the most appropriate. The difference in adsorption performance of several adsorbents was discussed from the point of view of the interlayer arrangement of the HDTMA. The kinetics of pertechnetate adsorption on HDTMA-bentonites was tested and analyzed using different surface reaction- and diffusion-based kinetic models. For all the investigated adsorbents, the most appropriate kinetic model was the pseudo-second-order kinetics model. The obtained adsorption capacities were and HDTMA-bentonites with HDTMA loadings exceeding CEC value should be regarded as very promising adsorbents for the remediation of Tc-99 polluted waters.

AB  - The diimine dioxime ligand, 3,3-(1,4-butanediyl-dinitrilo)bis-2-pentanone, 2,2-dioxime (LH2), containing a N-4 donor set was prepared by the Schiff base condensation of 2-hydroxyimino-3-pentanone and 1,4-diaminobutane in two ways: in a protic and in an aprotic solvent. A higher yield of the (LH2) imine was obtained when the synthesis was performed using a protic solvent (C2H5OH) instead of aprotic benzene (78 and 30 %, respectively). The Cu(II) metal complex of diimine dioxime was synthesized in CH3OH from the perchlorate salt of LH2 in a 1:1 mole ratio. The isolated complex was characterized by the elemental analysis, IR spectroscopy and cyclic voltammetry. The structure of [Cu-2(LH)(2)](ClO4)(2) was determined by single-crystal X-ray diffraction analysis.

AB  - In this thesis, the synthesis of four compounds from classes of diimine-dioximes have been given, and additionally after their reduction four compounds from classes of diamine-dioximes have been obtained, which have not been so far known in the literature.The synthesis of all four diimine-dioximes have been performed in a protic solvent (CH3OH or C2H5OH), at reflux or at room temperature, under nitrogen atmosphere, and optionally in the presence of a catalytic amount of CH3COOH. The synthesis in an aprotic solvent (benzene) has been performed for only two diimine-dioximes. After reduction of the corresponding diimine-dioximes with NaBH4 in C2H5OHanh, diamine-dioximes have been obtained.All obtained compounds have been characterized by elemental analysis, electronic absorption and IR spectroscopy, 1H and 13C NMR spectroscopy.Synthesized diamino-dioximes form complexes with radioactive isotope 99mTc. They contain four nitrogen atoms with free electron pairs and therefore act as electron donors in coordinating links with 99mTc (V). Because of this property, it have been examined whether the synthesized complexes with diamino-dioximes and 99mTc (V) may be used in the SPECT diagnostic nuclear medicine. For this purposes the following activities have been carried out: the labelling diamino-dioximes with 99mTc (V), the determination of the yield of labeled compounds, the determination of the stability of formed complexes, the determination of lipophilicity and protein binding of labeled compounds and biological monitoring of distribution (biodistribution) in experimental animals.Compounds from the class of diimine-dioximes easily form complexes with transition metals, and therefore with Cu(II).

AB  - Sorption of radioactive 99Tc-pertechnetate onto activated carbon prepared
from pinecones was investigated. The parameters of contact time and Tc-99
concentration were varied. It was established that the sorption half-life, t1/2,
was very short ~ 2.2 min, thus making this sorbent an excellent candidate
for immediate pollution remediation, which is very important in the case of
nuclear accidents. The kinetic data were found to follow closely the pseudosecond-
order (PSO) kinetic model. Boyd model established the sorption
dependence only on film diffusion. The partitioning/distribution coefficient,
Kd, attained was 2729 cm3 g-1. The equilibration time was 3 h at room
temperature (T=298 K).

AB  - The structure of binuclear Cu(II) complex containing double oximato
bridges was determined by the single-crystal X-ray diffraction analysis.
Copper is five-coordinated with perchlorato anion present at the borderline
of semi-coordination. Comparison with the structurally related diiminedioxime
Cu(II) complexes revealed the influence of the weak
Cu···O(perchlorate) interaction on the geometry of the metallocycle.

AB  - Two novel diamine dioxime ligands, 4,7-diaza-3,8-diethyldecane-2,9-dione bis oxime (3) and 4,9-diaza-3,10-diethyldodecane-2,11-dione bis oxime (5), were synthesized in order to develop new brain perfusion imaging agents, based on 99mTc(V)-complexes. The synthesis involved condensation of 2-hydroxyimino-3-pentanone with appropriate diamine in protic solvent which afforded the bis imine adducts. Subsequent reduction of imine functional groups yielded a diastereoisomeric mixture of 3 and 5. UVvisible, IR, 1H NMR, 13C NMR and elemental analysis were used to characterize the structures of the synthesized compounds. 99mTc-complexes of both diamine dioximes were prepared and radiolabeling conditions optimized to give the maximum yield. Physicochemical parameters of the labeled complexes as well as and their biodistribution in rats were investigated. Both compounds (3 and 5) formed 99mTc-complexes with a net charge of zero, determined by electrophoresis. The resultant lipophilic 99mTc-complexes of 3 and 5 were readily formed at pH similar to 9.0 within 10?min at room temperature with yields of 90% and 95%, respectively. The 99mTc-3 complex was found to be stable within 1 similar to h, while 99mTc-5 was stable for a few hours. A significant brain uptake of 99mTc-3 (2.1% injected dose) and 99mTc-5 (1.8% injected dose) complexes, 2?min after injection, is in accordance with their lipophilicity. The present study suggests that both ligands are promising candidates as new 99mTc-based brain-imaging agents. Copyright (c) 2012 John Wiley and Sons, Ltd.
