AB  - Radiation shielding is a crucial precautionary measure in decreasing the dose of exposure medical personnel experience. The physical dimensions of these shields, specifically thickness and shape, are dependent on the type of radiation, energy and specific radioactivity. Currently, the most common radiation shielding equipment is made of lead, tungsten or uranium. Although these heavy metals have favorable shielding properties against ionizing radiation, protective garments such as lead aprons are heavy to wear and can pose significant health risks. Taking this into account, the primary goal of this study is to understand the radiation shielding properties of lead-free polymer geopolymer-polyurethane based composites. The geopolymer was synthesized using an 80%-20% mixture of fly ash and a bio-polyol substrate which was subsequently homogenized using MDI44. As a result, 6 samples of the geopolymer-polyurethane based composites were fabricated of which 5 were 90%-10% compositions between the mixture and varying concentrations of BaSO4 and Bi2O3 respectively. The last sample consisted of the pure fly ash/bio-polyol mixture. XRF and ICP analysis was used to chemically characterize the fly ash. The composite structures were analyzed using XRD, while the microstructural morphology was investigated using SEM techniques. Utilizing an energy-dispersive x-ray spectrometer (EDS), elemental abundance and agglomerating behavior was analyzed for each composite variant. The X-ray attenuation measurements pointed out that the obtained composites have the potential for a design of lead-free protective clothing against X-ray shielding in medical applications.

In order to minimize the harmful effects of ionizing radiation on healthy tissues, the radioprotective properties of plant extracts are intensively researched. J. nigra husk contains a mixture of various pharmacologically active compounds that have an antioxidant effect and which are assumed to have a potential radioprotective effect. In this context, the aim of the work was to evaluate the radioprotective effect of black walnut husk extract. In this study, an experimental model was applied, which was based on the assessment of the effect of the extract on the biodistribution of Tc-99m-radiopharmaceuticals in the organs of experimental animals (rats). Black walnut husk extract led to a decrease in the accumulation of Tc-99m-radiopharmaceutical in certain organs of rats. The results obtained on the basis of the experimental model suggest that it is possible to use black walnut husk extract as a radioprotective agent in cases of planned exposure to ionizing radiation in diagnosticsnuclear medicine.

AB  - Prisustvo radiohemijske nečistoće C u 99mTc-MIBI injekciji utiče na kvalitet skena, jer se radiofarmaceutik nedovoljno nakuplja u organu od interesa, dok je aktivnost okolnih organa i tkiva velika. Zbog toga je i doza zračenja koju prime okolni organi i tkiva iznad propisanih granica. Da bi se obezbedilo da je planirano izlaganje zračenju pacijenata svedeno na minimum, farmakopeja zahteva ispitivanje sadržaja radiohemijske nečistoće C u 99mTc-MIBI injekciji neposredno pre primene radiofarmaceutika u pacijenta. Za ova ispitivanja se koriste metode hromatografije. U radu je predstavljena brza i osetljiva ITLC metoda namenjena za rutinsko ispitivanje sadržaja radiohemijske nečistoće C u 99mTc-MIBI injekciji. ITLC metoda je validirana, a ispitivani su pogodnost sistema, tačnost, preciznost, ponovljivost, specifičnost, limit detekcije, limit kvantifikacije, linearnost, robustnost i osetljivost metode. Dobre "recovery" vrednosti i niska relativna standardna devijacija potvrđuju da je predložena ITLC metoda pogodna za rutinsko određivanje nečistoće C u 99mTc-MIBI u injekciji.
AB  - The European Pharmacopoeia mandates that all radiopharmaceuticals used in nuclear medicine for diagnostic and therapeutic purposes must be of the correct radiochemical and radionuclidic purity and have the correct radioactivity present at the stated time of injection to ensure that the intended radiation exposure of patients is kept to a minimum. These factors have an effect on the overall radiation dose to the patient, as impurities of the radionuclide and/or its chemical composition may affect the biodistribution of the injected radiopharmaceutical and consequently the radiation dose to any one particular organ or the whole body dose. The presence of radiochemical impurity C in 99mTc-MIBI injection affects the quality of the image, because 99mTc-MIBI accumulates insufficiently in the organ of interest, while the activity of the surrounding organs and tissues is high. Therefore, the radiation dose received by the surrounding organs and tissues is above the permitted level. In order to avoid unnecessary irradiation of surrounding organs and tissues, the pharmacopoeia requires examination of the content of radiochemical impurity C immediately before administering of 99mTc-MIBI to the patient. Chromatographic methods are used for these tests. The paper presents a fast and sensitive ITLC method intended for routine examination of the content of radiochemical impurity C in 99mTc-MIBI injection. The ITLC method was validated, and the suitability of the system, accuracy, precision, repeatability, specificity, limit of detection, limit of quantification, linearity, robustness and sensitivity of the method were examined. Good "recovery" values and low relative standard deviation confirm that the proposed ITLC method is suitable for routine determination of impurity C in 99mTc-MIBI in injection.

Radijacioni efekti I-131 na ćelije štitaste žlezde potiču od beta-zračenja koje emituje I-131 tokom radioaktivnog raspada u samoj štitastoj žlezdi jer se I-131 nakon oralne primene nakuplja prvenstveno u štitastoj žlezdi u kojoj ima dugu retenciju. Za efikasnu terapiju, ali u isto vreme u cilju smanjenja izloženosti nepotrebnim dozama, za svakog pacijenta određuje se odgovarajuća doza I-131 koju je neophodno da primi, odnosno primenjuje se tzv. personalizovana terapija.

AB  - The Laboratory for radioisotopes of the Vinča Institute is a unique center in the region with licences of the Ministry of Health of the Republic of Serbia and the Directorate for Radiation and Nuclear Safety and Security of Serbia for the production of radiopharmaceuticals. Sodium iodide (I-131) capsules are radiopharmaceuticals that have been produced for more than 40 years in the Laboratory for Radioisotopes, and are used in the treatment of tumors of thyroid gland, as well as in hyperthyroidism. The radiation effects of I-131 on thyroid cells originate from beta-radiation emitted by I-131 during radioactive decay in the thyroid gland itself because I-131 after oral administration accumulates primarily in the thyroid gland where it has a long retention. For the effective therapy, but at the same time in order to reduce exposure to unnecessary high doses, the appropriate dose of I-131 is determined for each patient, in the so-called personalized therapy. The paper describes the current procedure for the production of I-131 capsules in the Laboratory for Radioisotopes by manually filling the capsules with I-131 solution and the basic requirements for design the system for automating the production of radiopharmaceuticals, which above all must provide adequate protection for the operator from radiation, must be user friendly and computer-controlled.

AB  - Metal complexes with BH4- ligands show extravagant structural and dynamic properties, and possess many important and applicable qualities (potent reducing agents and catalysts, materials for hydrogen storage). Electron paramagnetic resonance (EPR) is very important for the characterization of complex compounds, the determination of their electronic configuration and geometry. Also, Density Functional Theory (DFT) can predict EPR parameters and explain them more profoundly. Hence, in this paper hyperfine coupling constants of d and f metal complexes with BH4- ligands have been determined by DFT calculations, and analyzed in detail. Of particular importance is the analysis and prediction of hyperfine coupling constants for lanthanide complexes with BH4- ligands, given that there is not much data in the literature. Calculations predicted that proton hyperfine coupling constants are very small in the case of complexes of f elements, and are present only due to weak polarization. The increase of covalence and the number of unpaired electrons does not significantly affect the change of constants of BH4- ligands, but only of protons that are bound by σ bonds.

AB  - The rise of innovation in the electrical industry is driven by the controlled design of new materials. The hybrid materials based on magnetite/nanocellulose are highly interesting due to their various applications in medicine, ecology, catalysis and electronics. In this study, the structure and morphology of nanocellulose/magnetite hybrid nanomaterials were investigated. The effect of nanocellulose loading on the crystal structure of synthesized composites was investigated by XRD and FTIR methods. The presented study reveals that the interaction between the cellulose and magnetic nanoparticles depends on the nanocellulose content. Further, a transition from cellulose II to cellulose I allomorph is observed. SEM and EDS are employed to determine the variation in morphology with changes in component concentrations. By the calculation of magnetic interactions between adjacent Fe3+ and Fe2+ ions within composites, it is determined that ferromagnetic coupling predominates.

AB  - Surface modification of magnetic nanoparticles with poly-L-lysine, proline, and tryptophan was used to design potential theranostic agents for the application in cancer diagnosis and radionuclide-hyperthermia therapy. Characterization of bare and functionalized magnetic nanoparticles was performed in detail. The transparency of the examined magnetic nanoparticles was measured in the non-alternating magnetic field for a complete and better understanding of hyperthermia. For the first time amino acid-functionalized magnetic nanoparticles were labeled with theranostic radionuclides 131I and 177Lu. The specific absorption rate (SAR) procured for poly-L-lysine functionalized magnetic nanoparticles (SAR values of 99.7 W/g at H0 = 15.9 kA/m and resonant frequency of 252 kHz) demonstrated their possible application in magnetic hyperthermia. Poly-L-lysine functionalized magnetic nanoparticles labeled with 177Lu showed the highest radiochemical purity (>99.00 %) and in vitro stability in saline and serum (>98.00 % up to 96 h). The in vivo analysis performed after their intravenous administration in healthy Wistar rats presented good in vivo stability for several days. Encouraging results as well as magnetic and radiochemical properties of 177Lu–PLL-MNPs (80 °C) justify their further testing toward the potential use as theranostic agents for diagnostic and combined radionuclide-hyperthermia therapeutic applications.

AB  - The understanding of magnetic properties of metal complexes allow us to predict and design molecules and materials with required characteristics, which can be used to store the informations on quantum level. Molecular magnets, i.e. mononuclear systems with large magnetic anisotropy value are in the focus of interest due to their potential applications in quantum computing. Through the analysis of the factors that determine the magnetic properties of mononuclear complexes, it has been shown that [NiCl3(Hdabco)2] + (dabco=1,4- diazabicyclo[2.2.2]- octane) exhibit very high values of axial splitting parameter, D. The main cause for such a large value lies in interactions between dx2-y2 and dxy metal orbitals. The effects of Jahn-Teller distortion, which act opposed to spin-orbit coupling, are suppressed by the presence of voluminous dabco ligands, which are placed in axial position. Due to the steric hindrance of axial ligands, the chlorine atoms in equatorial plane can not move easily. Magnetic couplings between paramagnetic centers in binuclear complexes can be successfully analyzed using Broken Symmetry (BS) DFT method. The strength of magnetic interactions depends upon the electronic structure and the structure of bridging ligands. The distortions in the bridge region lead to a significant weakening of antiferromagnetic interactions. Detailed examinations have shown that highest values of coupling constants can be observed for complexes of nickel (II) and copper (II) due to the σ interactions between d metal orbitals and p bridging ligand orbitals. Furthermore, the rising number of unpaired electrons per metal center leads to the increase of antiferomagnetic and feromagnetic interactions at the same time. The antagonistic effects cancel each other, causing very small values of coupling constants. Magnetic interactions that are transmitted through the hydrogen bonds strongly depends on the orientation and arrangement of hydrogen bridges. In most examined cases Jahn-Teller distortion is the main cause of the absence of coupling.

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  - 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  - Light-transmitting measurements of white light and a consequentially chosen laser beam of 655 nm propagating through citrate- and oleate-coated CoFe 2 O 4 , FeFe 2 O 4 and MgFe 2 O 4 nanoparticles under the influence of an external magnetic field were presented. New experimental settings were developed for the optical study of ferrites’ behavior in ferrofluid with the applied magnetic field strength within the 30–400 mT range. A magnetic field-induced change of light transmittance occurred and a precipitation of all studied samples was obtained. Optical investigations of ferrofluid suspensions revealed that, contrary to the linear aggregates of colloidal CoFe 2 O 4 and FeFe 2 O 4 , spheroidal aggregates were formed in the case of MgFe 2 O 4 . In all three cases, the surface modification resulted in decreased dipole–dipole interactions between ferrite cores, and thus, less precipitates were noticed. All oleate-coated nanoparticles have demonstrated weaker magnetic responses compared to the citrate-encapsulated samples. The aggregation of nanoparticles potentially increases cytotoxicity. Regarding non-linear clustering of MgFe 2 O 4 suspensions, it can be concluded that its excretion from the organism may likely be easier and faster when used in diagnosis and/or therapy. Therefore, more attention should be paid to the lowly toxic MgFe 2 O 4 regarding its medical application. © 2019

AB  - The advances in nanotechnology are directed towards the development of new theranostic agents based on magnetic nanoparticles that can be used for both cancer detection and treatment. In this study, 2,3-dicarboxypropane-1,1-diphosphonic acid-coated magnetite nanoparticles (Fe3O4-DPD MNPs) were evaluated for their theranostic application using different methods. The magnetic hyperthermia efficiency of the Fe3O4-DPD MNPs was investigated in saline solution with ionic strengths between 0.05 and 1.0 mol dm(-3). For a better understanding of hyperthermia, the behavior of Fe3O4-DPD MNPs under a non-alternating magnetic field was studied, and the transparency of the sample was measured. Furthermore, the radiotracer method using the radionuclides Tc-99m and Y-90 was applied as a reliable and powerful method for evaluating the in vivo behavior of a nanoprobe; a high radiolabeling yield (>93%), in vitro and in vivo stability of the radiolabeled nanoparticles and high heating effect were observed, thus paving the way for the possible theranostic applications of Fe3O4-DPD MNPs.

AB  - In this work we present the synthesis, and experimental and theoretical analysis of a binuclear nickel(II) complex coordinated to a new phthalazine dihydrazone-based ligand. Single-crystal X-ray diffraction analysis of the metal complex shows that the coordination geometry around each nickel(II) atom is distorted octahedral. DFT calculations predict that the magnetic exchange coupling constant of the binuclear nickel(II) complex is predominantly anti-ferromagnetic.

AB  - In present work boron doped diamond (BDD) electrode was applied for studying electrochemical behavior, as well as for quantitative determination of natural alkaloid, tubocurarine (arrow poison/ TUB). Electrochemical behavior was investigated using several organic solvents and aqueous buffers, at different pHs, as supporting electrolytes. After selection of the most appropriate supporting electrolyte and investigation of its electrochemical behavior, analytical procedures for quantitative analysis of TUB were developed in an acetonitrile/methanol (80:20) mixture and in 1 mol L−1 nitric acid, which had linear quantification ranges from 4 × 10−6 to 1 × 10−4 mol L−1 (LOD = 3.07 × 10−6 mol L−1) and 4 × 10−6 to 9 × 10−5 mol L−1 (LOD = 2.45 × 10−6 mol L−1 and 5.28 × 10−7 mol L−1, depending on the selected peak), respectively. The oxidation mechanism of TUB was proposed from the theoretical aspect. Remarkable selectivity and good sensitivity were obtained after the TUB quantification method was optimized, allowing application of the developed method for TUB quantification in biological fluids, with excellent reproducibility, accuracy and precision.

AB  - Doze kalibrator je jedan od osnovnih uređaja u nuklearnoj medicini, koji se koristi za merenje aktivnosti (doza) radiofarmaceutika koji se daju pacijentima bilo u dijagnostičke ili u terapijske svrhe. Aktivnosti gama i beta emitera različitih energija moraju da budu izmerene što tačnije da bi izlaganja ljudi (pacijenata) jonizujućem zračenju bila svedena na najmanji mogući nivo, a da se dobiju klinički značajni rezultati. Početna tačnost kalibratora (nesigurnost 5% ili manje) može se vremenom menjati kao rezultat promene pritiska u jonizacionoj komori ili električnog drifta.

AB  - A dose calibrator is an essential device in a nuclear medicine, utilized for measurement the activity of radiopharmaceuticals administered to patients both for diagnostic and therapeutic purposes. It has to measurethe radioactivity of gamma and beta with different energies precisely for high quality imaging and for applying the right amount of radiation to treat disease. Initial accuracy (uncertainty 5% or less) may change with time as a result of changing pressureof the chamber gas and slow electrical drift. The quality controls should be undertaken on a routine basis to ensure the accuracy and traceability of measurements of the activities of radiopharmaceuticals.The paper presents the results of estimation of uncertainty in the measurement of the activity in the dose calibrator in the Laboratory for radioisotopes. The uncertainty components, that are important for these measurements, are identified and taken into account while estimating the uncertainty of measurement. Understanding the source of uncertainty and using appropriate techniques can minimize inaccurate measurements.

AB  - Using simple optical measurements, the selective spectral behavior of suspended nano-particles of magnetite (Fe3O4) and cobalt-ferrite (CoFe2O4) coated with starch, was observed through switching on/off of external magnetic field. The field strength was varied in the interval 30–300 mT. In these transient regimes, the unexpected and unusually large changes of transmitted light occur. An explanation is suggested, within the model based on ordering of magnetic moments of nano-particles along the lines of magnetic field into magnetic chains and organization of magnetic chains into spatial structure—a quasi-lattice. This fact indicates the possibility of more efficient local heating of nano-particles in the fast changing magnetic field; for instance when taking magnetic nano-particles for therapeutic purposes.

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.

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.",
