AB  - J. nigra leaf contains mixture of various pharmacologically active compounds and it is assumed that they may have the potential radioprotective effect. The purpose of this work was to predict radioprotective doses by correlating changes in organ distribution of radiopharmaceuticals with extract dose levels and rat body weight using response surface methodology (RSM) based on a second-order polynomial equation. The extract was administered daily by oral gavage to rats at dose of 6.9, 10.3, or 13.7 mg kg−1 body weight (bw) day−1 for 10 days. On the eleventh day, 0.1 ml of the one radiopharmaceutical (Na99mTcO4, 99mTc-dimercaptosuccinic acid and 99mTc-tin colloid) was injected into the tail vein. The statistical parameters: the coefficient of determination (0.81–0.95), the coefficient of variation (3.05–11.1), the adequate precision (8.82–19.12) and the mean relative percentage deviation (± 2.3–8.2) were indicated the precision and reliability of RSM. Using RSM, the predicted daily dose of leaf extract ranging from 11.19 to 11.99 mg kg−1 bw may be considered as an optimal daily radiopotective dose for protection of organs from radiation in cases of planned radiation exposures.

AB  - As an alternative to classical brachytherapy, intratumoral injection of radionuclide-labeled nanoparticles (nanobrachytherapy, NBT) has been investigated as a superior delivery method over an intravenous route for radionuclide therapy of solid tumors. We created superparamagnetic iron oxide nanoparticles (SPIONs) coated with meso-1,2-dimercaptosuccinic acid (DMSA) and radiolabeled with Lutetium-177 (177Lu), generating 177Lu-DMSA@SPIONs as a potential antitumor agent for nanobrachytherapy. Efficient radiolabeling of DMSA@SPIONS by 177Lu resulted in a stable bond with minimal leakage in vitro. After an intratumoral injection to mouse colorectal CT-26 or breast 4T1 subcutaneous tumors, the nanoparticles remained well localized at the injection site for weeks, with limited leakage. The dose of 3.70 MBq/100 µg/50 µL of 177Lu-DMSA@SPIONs applied intratumorally resulted in a high therapeutic efficacy, without signs of general toxicity. A decreased dose of 1.85 MBq/100 µg/50 µL still retained therapeutic efficacy, while an increased dose of 9.25 MBq/100 µg/50 µL did not significantly benefit the therapy. Histopathology analysis revealed that the 177Lu-DMSA@SPIONs act within a limited range around the injection site, which explains the good therapeutic efficacy achieved by a single administration of a relatively low dose without the need for increased or repeated dosing. Overall, 177Lu-DMSA@SPIONs are safe and potent agents suitable for intra-tumoral administration for localized tumor radionuclide therapy

AB  - In the last decades, self-heating magnetic nanoparticles (MNPs) were engineered and investigated for magnetic hyperthermia (MH) and other applications such as catalysis and chemical synthesis. To be applied as nanoheaters for in vivo MH in cancer therapy, MNPs should have high heating efficiency expressed by Intrinsic Loss Power (ILP). One of the requirements for in vivo applications of MNPs is their non-toxicity. Hence, the most investigated MNPs for MH are based on iron oxides (magnetite and maghemite), which are non-toxic or slightly toxic. This work aimed to apply thepolyol-mediated protocol to engineer mixed Zn1-xMnxFe2O4 and analyze their heating abilities. To obtain a series of Zn1-xMnxFe2O4 samples with a specific nominal composition, the initial components, salts of Zn, Mn and Fe, were mixed in the appropriate stoichiometric ratio. The deviation from the target stoichiometry and the formation of samples with polyvalent ions and possibly vacancies were determined after ICP analysis. By analyzing TEM micrographs, we found that the change in the chemical composition does not affect the morphology. Multicore flower-like nanostructures with a size in the range of 47-63 nm were obtained. They consist of many cores (crystallites or nanoparticles) with a size of \textasciitilde10 nm. The samples show good colloidal stability, which is significant for their medical applications. Magnetization measurements in different DC fields showed that the samples are superparamagnetic at 300K and that the saturation magnetization values are in the range of \textasciitilde59-73 emu/g. The hyperthermic efficiency of the synthesized samples was tested in an external ac field of 252 kHz and a field strength of 15.9 kA/m. Significantly different values were obtained for the ILP parameter (in units nHm2/Kg): 5.77 (Zn0.098Mn0.447Fe2.455O4) ˃ 3.22 (Mn0.624Fe2.376O4) ˃ 2.04 (Zn0.182Mn0.344Fe2.474O4) ˃ 1.36 (Zn0.309Mn0.240Fe2.451O4) ˃ 1.01 (Zn0.394Mn0.138Fe2.468O4) ˃ 0.34 (Zn0.640Fe2.360O4). To explain the values of the ILP parameter, additional research is required, which includes the analysis of the influence of local defects and cation distribution on the magnetism of the investigated nanostructures. Also, significantly high ILP values indicate that some samples can be selected and further tested for in vitro/in vivo applications.

AB  - A series of MgxFe3-xO4 (x=0, 0.1, 0.2, 0.4, 0.6, 0.8, and 1) magnetic nanoparticles (MNP) were synthesized by a two-step procedure, a co-precipitation method followed by hydrothermal treatment in a microwave field. The MNP are single-core, with crystallite size gradually decreasing from 15.5(3) up to 2.5(3) nm with an increase ofx. TEM images show pseudospherical log-normally distributed particles with an average particle diameter of 19.8 nm and a polydispersity index of 26.1% for magnetite. The particle diameter decreases with the increase of magnesium (x) in the formula unit. The colloidal stability of MNP was achieved by their surface modification with citric acid (CA), oleic acid (OA) and polyethylene glycol (PEG). The cytotoxic activity of uncoated and coated Mg0.6Fe2.4O4 was tested against target malignant cells (HeLa, LC174, A549) and normal MRC5 cells. The investigated MNP show moderate cytotoxic activity against the tested malignant cells in vitro. In contrast, MNP didn’tshow any significant cytotoxic effect against normal cells. HeLa cells exhibited the highest susceptibility among the malignant cells. Mg0.6Fe2.4O4@OA show good cytotoxic activity against all examined malignant cells, significantly higher than other tested MNP. It can be seen that Mg0.6Fe2.4O4@PEG show a lower cytotoxic activity compared to all analyzed MNP. A direct method was used for labeling with radionuclide 90Y, which involves incubation of MNP with 90Y at a certain temperature and time. The labeling yield of the 90Y-coated MNP was determined by analyzing the radiochemical purity after labeling. 90YMg0.2Fe2.8O4@PEG were labeled in high yield (100%), while the yield for 90YMg0.2Fe2.8O4@CA was 83%. In vitro stability of 90Y-coated MNP at room temperature in physiological solution and human serum was monitored within 72 h from the moment of labeling by determining the radiochemical purity of ITLC-SG by radio chromatographic method. The stability of 90Y-Mg0.2Fe2.8O4@PEG was about 97%, while 90Y-Mg0.2Fe2.8O4@CA stability was 73%. The results of this study indicate that radiolabeled surface-modified (Mg, Fe)3O4 can be used as vectors in radionuclide therapy of malignant diseases.

AB  - Nanomaterials are intensively researched both from the fundamental aspect due to new properties at the nanoscale, as well as the aspect of their application in many areas of technology. Magnetic nanoparticles (MNPs) are being tested for use in the diagnosis and therapy of diseases. A new field of medicine, Magnetic nanomedicine is primarily based on the application of MNPs as drug carriers, diagnostic agents in Magnetic Resonance Imaging (MRI) and heat generators in magnetic hyperthermia. Among nanoparticles, magnetic nanoplatforms based on iron oxides for cancer diagnosis and therapy (Cancer nanomedicine) are the most researched and clinically tested. This study presents the results of research into the physicochemical properties of iron oxide nanoparticles prepared by the polyol route, as well as their testing for potential applications as agents in magnetic hyperthermia (MH) and radionuclide carriers (vectors) for the diagnosis and therapy of malignant diseases. Multicore iron oxide structures synthesized by the "polyol" method represent clusters of single-core nanoparticles or crystallites. The dimensions of the single core particles are \textasciitilde13.5 nm, while the nanoflowers formed by clustering are \textasciitilde25 nm, depending on the applied synthesis parameters. For targeted medical applications, nanoflowers are coated with different ligands in order to increase colloidal stability and biocompatibility. The best results were by coating MNPs with polyacrylic acid (PAA). The multifunctionality of nanoflowers was investigated by measuring their hyperthermic efficiency for applications in magnetic hyperthermia and radiolabeling with diagnostic (99mTc) and therapeutic radionuclides (177Lu, 90Y). In addition to traditional methods of cancer therapy (surgery, radiotherapy, and chemotherapy), new ways of therapy such as MH are constantly being developed. MH is a therapy based on the property of MNPs that when placed in an alternating (AC) magnetic field, transform the electromagnetic energy of the field into heat. When located inside a tumor, MNPs can locally generate a temperature of 42-46 °C and destroy cancer cells by heat. The hyperthermic efficiency of MNPs is expressed through the Intrinsic Loss Power (ILP) parameter. The measured ILP was 7.3 nHm2/kg which is considered one of the higher reported values found in the literature for iron oxides. Nanoflowers were radiolabeled with 99mTc, 177Lu, and 90Y radionuclides. The in vitro stability of radiolabeling was investigated. Good in vitro stability indicates that the formed radioactive particles can be used simultaneously for bi-modal cancer therapy (MH and radionuclide therapy) or for MH therapy and diagnostics (theranostics), in the case of labeling with 99mTc.

abstract = "Nanomaterials are intensively researched both from the fundamental aspect due to new properties at the nanoscale, as well as the aspect of their application in many areas of technology. Magnetic nanoparticles (MNPs) are being tested for use in the diagnosis and therapy of diseases. A new field of medicine, Magnetic nanomedicine is primarily based on the application of MNPs as drug carriers, diagnostic agents in Magnetic Resonance Imaging (MRI) and heat generators in magnetic hyperthermia. Among nanoparticles, magnetic nanoplatforms based on iron oxides for cancer diagnosis and therapy (Cancer nanomedicine) are the most researched and clinically tested. This study presents the results of research into the physicochemical properties of iron oxide nanoparticles prepared by the polyol route, as well as their testing for potential applications as agents in magnetic hyperthermia (MH) and radionuclide carriers (vectors) for the diagnosis and therapy of malignant diseases. Multicore iron oxide structures synthesized by the "polyol" method represent clusters of single-core nanoparticles or crystallites. The dimensions of the single core particles are \textasciitilde13.5 nm, while the nanoflowers formed by clustering are \textasciitilde25 nm, depending on the applied synthesis parameters. For targeted medical applications, nanoflowers are coated with different ligands in order to increase colloidal stability and biocompatibility. The best results were by coating MNPs with polyacrylic acid (PAA). The multifunctionality of nanoflowers was investigated by measuring their hyperthermic efficiency for applications in magnetic hyperthermia and radiolabeling with diagnostic (99mTc) and therapeutic radionuclides (177Lu, 90Y). In addition to traditional methods of cancer therapy (surgery, radiotherapy, and chemotherapy), new ways of therapy such as MH are constantly being developed. MH is a therapy based on the property of MNPs that when placed in an alternating (AC) magnetic field, transform the electromagnetic energy of the field into heat. When located inside a tumor, MNPs can locally generate a temperature of 42-46 °C and destroy cancer cells by heat.

AB  - Juglansnigraleaf is a source of health-promoting biologically active compounds and used in traditional
medicine. Can we predict theradioprotective dose level of plant extracts based on modeling change
biodistribution of radiopharmaceuticals by response surface methodology (RSM)? The present study aimed
to the effects of J. nigra leaf extract oral intake on the biodistribution of 99mTc-radiopharmaceutical in
healthy rats and to formulate a mathematical model that will associate the changes in radioactivity in organ
with dose levels of extract and body mass of rats. The extract was administered daily by oral gavage to rats at
dose levels of 6.9, 10.3, or 13.7 mg kg-1 body weight (bw) day-1 for 10 days. On the eleventh day, 0.1 ml
(approximately 148 kBq) of the 99mTc-dimercaptosuccinic acid (DMSA) was injected into the tail vein. The
organs of interest were isolated and radioactivity in each organ was counted by a gamma counter with a NaI
(Tl) detector. After treatment of rats with the extract, there was a statistically significant decrease (p<0.05) in
the uptake of 99mTc-DMSA (%ID/organ) in the kidneys compared to controls.The RSM model based on the
second-order polynomial equation was apply to correlate changes in radioactivity in kidney with dose levels of
extract and body mass of rats.The statistical significance of RSM as well as independent variables and their
interactions were estimated by ANOVA (Analysis of variance). The F-value (265) and p-value (< 0,001)
demonstrated that the developed model has statistical significance at the confidence level of 95%. The R2
values (0.987) proved a good fit by the second-order polynomial equation, while relatively low values of the
CV (0.69) indicated the remarkable precision and reliability of the model. The low value of mean relative
percent deviation (0.4) between the experimental data and the predicted radioactivity of kidney obtained by
RSM showed that RSM was suitable for modeling the change biodistributionof radiopharmaceutical.
Modeling data provided evidence that the radioactivityof kidney statistically depended dose levels of extract
and statistically not depended of body mass of rats. RSM gave the minimum predicted value of radioactivity
of kidney 59%, which corresponded to minimum dose levelof 11.18 mg kg-1and minimum body massof 130 g.
RSM showed that extracts of J. nigraleaf kidney system protectionat doses higher than 11.18 mg kg-1. These
results suggest the potential use minimal dose level of J. nigraleaf extract as a radioprotector in cases of
planned radiation exposures.

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.

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.

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, determination of their electronic configuration and geometry. Also, Density Functional Theory (DFT) can predict EPR parameters and explain them more profoundly. 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. Within this paper hyperfine coupling constants of d and f metal complexes with BH4 - ligands have been determined by DFT calculations, and analyzed in detail. 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  - Novel methods of cancer therapy are constantly being investigated since the current approach heavily relies on the use of non-specific and toxic chemotherapy agents. Ideally, a drug used for cancer therapy would specifically target tumor sites or rather bind specifically with cancer cells. The way to achieve this is by targeting cancer cell specific receptors or receptors present in abnormally high counts at the surface. Rapid proliferation of cancer cells is fueled by large amounts of energy that is in turn produced by abnormal glucose uptake. Because of this high energy/glucose demand, cancer cells exhibit an abnormally high glucose receptor (GLUTs) count on their surface, compared to normal, healthy cells. We have utilized this glucose dependency to create glucose modified liposomes (Glucosomes) that are specifically bound by cancer cells. Glucosomes can be used to transport different substances, either hydrophilic or hydrophobic, and can therefore deliver any type of drug to cancer cells, increasing its efficiency. Another important aspect to consider is the controlled release of the drug being transported in order to maximize therapeutic efficiency. Controlled release can be achieved by utilizing different internal or external influences. In our study, we have used standard Fe3O4 magnetic nanoparticles to load glucosomes and induce their controlled opening via an external magnetic field. By applying an external magnetic field, the magnetic nanoparticles start heating up and transferring this thermal energy to the surrounding lipid bilayer, causing its perturbation and opening of the glucosome. Our study has found that controlled release can be achieved with high efficiency while the chemical stability of the Fe3O4 nanoparticles stays practically intact. Using EPR spectroscopy, we have shown that Fe3O4 nanoparticles remain trapped within the lipid bilayer and are essentially protected from oxidation that would diminish their magnetic properties. Since magnetic Fe3O4 nanoparticles are lodged well within the lipid bilayer no thermal damage can be caused to the drug being transported within the glucosome bilayer, making this a viable controlled release cancer targeting drug delivery system.

AB  - Radiolabelled superparamagnetic iron oxide nanoparticles (SPIONs) are a promising nanomaterial for the development of dual radiation/hyperthermia cancer therapy. To that purpose, flower-shaped SPIONs with an exceptional heating capability were synthesised and coated with citrate, dextran or (3-aminopropyl)triethoxysilane. Both non-coated and coated SPIONs were nontoxic to CT-26 mouse colon cancer cells up to 1.0 mg ml−1 in vitro. In an oscillating magnetic field, citrate-coated SPIONs (CA/SPIONs) displayed the highest heating rate (SAR ∼ 253 W g−1) and the strongest hyperthermia effects against CT-26 cells. Labelling of the CA/SPIONs by the 90Y radionuclide, emitting β− radiation with an average/maximum energy of 0.94/2.23 MeV, and deep tissue penetration generated 90Y-CA/SPIONs intended for the therapy of solid tumours. However, intravenous injection of 90Y-CA/SPIONs in CT-26 xenograft-bearing mice resulted in low tumour accumulation. On the contrary, intratumoural injection resulted in long-term retention at the injection site. A single intratumoural injection of 0.25 mg CA/SPIONs followed by 30-min courses of magnetic hyperthermia for four consecutive days caused a moderate antitumour effect against CT-26 and 4T1 mouse tumour xenografts. Intratumoural application of 1.85 MBq/0.25 mg 90Y-CA/SPIONs, alone or combined with hyperthermia, caused a significant (P ≤ 0.01) antitumour effect without signs of systemic toxicity. The results confirm the suitability of 90Y-CA/SPIONs for monotherapy or dual magnetic hyperthermia-radionuclide nanobrachytherapy (NBT) of solid tumours.

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  - Iron oxide-based magnetic nanoparticles (MNPs) are promising candidates for dual radiation and magnetic hyperthermia cancer therapy (MHT). Although iron oxide nanoparticles are currently approved by FDA for imaging purposes and for the treatment of anaemia, magnetic nanoparticles designed for the efficient magnetic hyperthermia cancer treatment must respond to specific physicochemical properties in terms of magneto-energy conversion, heat dose production, surface chemistry and aggregation state. In the past few decades, these requirements have boosted the development of a new generation of MNPs specifically aimed for MHT. Between various synthesis pathways, specific assembly of small nanoparticles into flower-shaped structures, achieved in polyol-mediated synthesis opened new avenues for MNPs hyperthermia cancer treatment. High heat generation in MHT was most-probably a consequence of the specific organization and agglomeration of individual cores inside each particle and their interaction in external alternating magnetic field. When we add to that, low cytotoxicity, the possibility of surface modification and further functionalization, then polyol-prepared MNPs emerge as one of the best candidates for combined cancer therapy. In our recent studies, we have coated magnetic nanoflowers prepared by polyol-mediated synthesis with various organic ligands (citric acid, polyethylene glycol, (3- aminopropyl)triethoxysilane) and successfully radiolabelled them with high-energy beta emitters 90Y, 177Lu and 131I, as well as gamma emitter 99mTc, which can be used both as therapeutic and diagnostic agents. Finally, we have successfully applied these magnetic nanoconstructs in combined magnetic hyperthermia-radionuclide nanobrachytherapy of CT-26 mouse colon and 4T1 metastatic mouse breast tumours.

AB  - Juglans nigra L. (Black walnut) green husk contains a variety of useful chemical compounds with numerous health benefits. However, the biological effects of these compounds are not fully known. The aim of this research was to evaluate the effect of the extracts from J. nigra green husks on the biodistribution of the sodium pertechenetate (Na99mTcO4). The extract was orally administered to the healthy Wistar rats (male, 1-month-old, weighing 89.4±3.4g) at single doses of 13.7 mg/kg/day by gavage for 10 days. On the eleventh day, 0.1 ml (approximately 148 kBq) of the Na99mTcO4 was injected into the tail vein. Rats were sacrificed at different time intervals and the radioactivity in the organs of interest was measured in a gamma counter with a NaI (Tl) detector. The percentage of radioactivity per organ (%ID/organ) was calculated. The organ uptake of the Na99mTcO4 in an additional control group of animals was also studied. The results obtained showed an alteration in the organ uptake of Na99mTcO4 in rats treated with extract. The radiopharmaceutical Na99mTcO4 is generally distributed throughout the vasculature and interstitial fluid and is concentrated in the stomach, intestinal tract, thyroid and salivary glands. After treatment of rats with the extract, there was a statistically significant decrease (p<0.05) in the uptake of Na99mTcO4 (%ID/organ) in the thyroid, heart, kidneys, liver and colon, and an increase in intestinal uptake compared to controls. These results are associated with properties of the chemical compounds present in the J. nigra extract. We assume that the compounds from the extract J. nigra could promote physiological modifications in these organs and alter the biodistribution of Na99mTcO4 in the treated animals. Although these research studies were performed in animals, the findings suggest that caution should be exercised while interpreting the results of Na99mTcO4 based nuclear medicine examinations in patients using J. nigra extract from green husk.

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  - The combination of two imaging modalities in a single agent has received increasing attention during the last few years, since its synergistic action guarantees both accurate and timely diagnosis. For this reason, dual-modality contrast agents (DMCAs), such as radiolabeled iron oxide (namely Fe3O4) nanoparticles, constitute a powerful tool in diagnostic applications. In this respect, here we focus on the synthesis of a potential single photon emission computed tomography/magnetic resonance imaging (SPECT/MRI) DMCA, which consists of Fe3O4 nanoparticles, surface functionalized with 2,3-dicarboxypropane-1,1-diphosphonic acid (DPD) and radiolabeled with 99mTc, [99mTc]Tc-DPD-Fe3O4. The in vitro stability results showed that this DMCA is highly stable after 24 h of incubation in phosphate buffer saline (~92.3% intact), while it is adequately stable after 24 h of incubation with human serum (~67.3% intact). Subsequently, [99mTc]Tc-DPD-Fe3O4 DMCA was evaluated in vivo in mice models through standard biodistribution studies, MR imaging and gamma-camera imaging. All techniques provided consistent results, clearly evidencing noticeable liver uptake. Our work documents that [99mTc]Tc-DPD-Fe3O4 has all the necessary characteristics to be a potential DMCA.

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  - 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  - A series of Fe3-xGdxO4 (x = 0, 0.1, 0.2) nanoparticles with an average diameter of around 8 nm were prepared by the coprecipitation method and coated by citric acid (CA). The nanoparticles show superparamagnetic behavior at room temperature and transition to a blocked state, at a temperature from ~ 89 K to ~ 213 K, depending on Gd concentration. The saturation magnetization of Fe3-xGdxO4 tended to drop for samples with a higher content of Gd. High colloidal stability is mandatory in medical applications of magnetic nanoparticles, and here we demonstrate a new procedure for its improvement. A colloidal sample of Fe3O4@CA was mechanically milled, after which dynamic light scattering and zeta potential measurements were used to monitor the hydrodynamic size and colloidal stability of the acquired suspensions. After 90 min of milling, the average hydrodynamic diameter decreased by 40%, and size distribution changed from polymodal to monomodal, while the negative zeta potential increased from − 30.5 mV to − 52.8 mV. Additionally, Fe2.80Gd0.20O4@CA nanoparticles were embedded in human serum albumin to produce magnetic microspheres (MMS), which could be used as a drug delivery platform. FE-SEM images showed that magnetic nanoparticles form clusters within MMS. © 2021, The Author(s), under exclusive licence to Springer-Verlag GmbH, DE part of Springer Nature.

AB  - S-Adenosyl-L-Homocysteine (AdoHcy) is a crucial pathological factor in homocysteine-associated disorders. We developed an impedimetric approach for single drop S-Adenosyl-L-Homocysteine detection, based on S-Adenosyl-L-Homocysteine hydrolase (SAH), produced in the prokaryotic expression system (E. coli) by recombinant DNA technology, immobilized on citrate acid-coated gallium oxyhydroxide dispersed over single-walled carbon nanotubes (CA/GaO(OH)@SWCNT). The proposed biosensor offers detection of AdoHcy, with a limit of detection (LOD) of 0.17 μM. with operating linear range from 1 to 44 μM. The remarkable stability of gallium oxyhydroxide crystal was further improved by citric acid coating and its optical, electrical and physical anisotropy was skipped using SWCNTs.

We developed an impedimetric approach for single drop S-Adenosyl-L-Homocysteine detection, based on S-Adenosyl-L-Homocysteine hydrolase (SAH), produced in the prokaryotic expression system (E. coli) by recombinant DNA technology, immobilized on citrate acid-coated gallium oxyhydroxide dispersed over single-walled carbon nanotubes (CA/GaO(OH)@SWCNT). The proposed biosensor offers detection of AdoHcy, with a limit of detection (LOD) of 0.17 μM. with operating linear range from 1 to 44 μM. The remarkable stability of gallium oxyhydroxide crystal was further improved by citric acid coating and its optical, electrical and physical anisotropy was skipped using SWCNTs.",

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  - The goal of this work was to develop green electrode material that unites all advantages of domestic made, synthesized porous carbon powder and ceria dioxide nanoparticles known due to exceptional catalytic properties. Thermal decomposition of Novolac phenol-formaldehyde resin and cerium sulfate resulting in producing a high-performance CeO2 porous carbon material highly sensitive to dopamine (DA) electrooxidation. Morphological and structural characteristics of the material were determined by SEM and XRD measurements, while electrochemical characterization was performed by EIS and CV. The sensitivity of DA determination on the proposed CeO2-doped carbon material was enhanced by adding multi-wall carbon nanotubes to finally prepare a mixture for a specific carbon paste electrode (TPCeO2&MWCNT@CPE). SWV technique was used for quantification of dopamine in Britton-Robinson buffer pH 6 in the concentration range of 0.5-100 μM of DA, with the detection limit of 0.14 μM and quantification limit of 0.44 μM. Good selectivity overstudied bioactive compounds enables the successful and efficient application of the proposed electrode and developed an analytical procedure for the determination of dopamine in spiked urine samples.
