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  - The homemade, porous carbon material, thermolysis prepared from Novolac phenol-formaldehyde resin, in situ modified with Co3O4 nanoparticles and mixed with single-wall carbon nanotubes, was used in selective sensing of prominent antioxidant α-lipoic acid (LA). XRD, SEM and EIS measurements were used for characterization of material composition, structure, morphology and improved conductivity. The quantification of LA at TPCo3O4&SWCNTCPE was done by a square-wave voltammetric technique in BR buffer solution at pH 6. The linear working range was recorded from 2 to 100 μM of LA and the proposed electrode material was successfully applied in the determination of LA in dietary supplements.

AB  - Type of the wood used for the aging highly influences the quality of alcoholic beverages. In this research we explored the potential of cyclic voltammetry (CV) and differential pulse voltammetry (DPV) to establish fingerprints characteristic for each wood and to enable determining the type of the wood used in the aging process. Eleven different wood samples were used to prepare three different types of spirits during 15 months. The highest extraction rate was obtained during the first month, while further aging was followed with almost constant amount of extracted polyphenols. Black locust, myrobalan plum, and mulberry extracts were discriminated from the spirits aged in oak and wild cherry wood when statistical analysis was applied. Although clear classification of all samples was not achieved, this long term study demonstrated a potential of both CV and DPV for differentiating wood species used in the aging, hence in the quality control of spirits. © 2020 Elsevier Ltd

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.

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  - Iron oxide nanoparticles (IONP) with different distinctive morphologies (spherical, cubic, flower-like and needles) were utilized for modification of screen-printed carbon electrodes (SPCE) to be used for synthetic organic dye degradation by an electrochemical approach. This platform was implemented for removal of the synthetic organic dye, Reactive Black 5 (RB5) in aqueous solution. Modified SPCE with spherically shaped IONP (IONS) had the highest dye removal efficiency. Thus, IONS were then used for surface decoration of the most common carbon-based materials (graphene, graphene oxide, carboxylated graphene, graphene nanoribbons, graphene nanoplatelets, single- and multi-wall carbon nanotubes), and the nanocomposites formed were deposited on the electrode surfaces. Using IONS/graphene composite (IONS@GN) for electrode modification resulted in the best effect. Removal of RB5 with this electrode was 51% better in comparison with bare SPCE, reducing the time required for complete dye degradation from 61 to 30 min Using IONS-modified SPCE, total RB5 removal occurred in 51 min, improving the performance by 16% over that of bare SPCE. The effects determined, i.e., the best IONP morphology and best type of carbon-based material for nanocomposite formation to enhance RB5 removal will provide guidelines for further modifications of SPCE with nanomaterials and nanocomposites, for application of this electrochemical approach in the degradation of organic pollutants. © 2020 The Author(s).

AB  - In order to ensure high food quality, one of the prime importance is the detection and quantification of histamine, well known marine food poison. In this work, we constructed novel electrochemical biosensor for the detection of histamine based on gold nanoparticles decorated on manganese dioxide (Au/MnO2) and used for modification of screen-printed carbon electrode (Au/MnO2@SPCE). The constructed sensor was then used for the estimation of histamine content in a single drop. Materials used in this study were synthesized and characterized using HR-TEM, XRPD and electrochemical methods. The amperometric detection method was optimized and, under selected operating parameters (supporting electrolyte pH 6, working potential of 1 V), the proposed sensor possesses linear working range from 0.3 µM to 5.1 µM, with a detection limit of 0.08 µM. The effect of selected interferences was investigated and it was found that the developed approach offers accurate, precise, selective, fast and reproducible quantification of histamine using only one drop of the sample. In the end, this work stands as a proof-of-concept of the modified electrodes and electrochemical detection as a promising and prospective approach for the applications in real-time monitoring of the food quality.

AB  - Herein, we proposed a novel approach and state-of-the-art technology for the improvement of the materials and enzyme immobilization at the electrode surface and construction of impedimetric glucose biosensor. We silanized titanium dioxide nanoparticles using (3-aminopropyl)triethoxysilane (APTES), for the preparation of cross-linked material nanoparticles, with carboxylic graphene. The silanization of titanium dioxide nanoparticles and an increase in electron shuttle was proven feasible when this composite was able to achieve about 30% higher current than non-silanized material. The proposed approach was used for the modification of the printed three-electrode system and the development of the impedimetric glucose biosensor. The material morphology and electrochemical characteristics were confirmed by spectroscopic and electrochemical methods. The present combination effectively modified the electrode surface and serve as a promising basis for the construction of Point-of-Care devices. Developed biosensor possesses wide operating linear range toward glucose detection from 50 µmol to 1000 µmol, with the limit of detection of 24 µmol. Finally, negligible interference effect and application in the real sample indicate that the proposed mechanism can be successfully applied to the assessment of glucose level in only one drop of real sample.

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.

AB  - Dual-modality contrast agents (DMCA), such as radiolabeled magnetic nanoparticles, have attracted significant attention in diagnostic applications due to their potency for the timely and accurate diagnosis of diseases. The hemocompatibility of a candidate DMCA with human blood is essential for the investigation of its application in vivo. In this respect, here we focused on the evaluation of the hemocompatibility of a new DMCA, that is based on iron oxide nanoparticles (i.e. Fe3O4 magnetite), with human red blood cells (RBCs). The specific iron oxide nanoparticles are surface functionalized with 2,3-dicarboxypropane-1,1-diphosphonic acid (-DPD) and radiolabeled with gallium-68 (68Ga), resulting in 68Ga-DPD-Fe3O4. RBCs of five healthy individuals are incubated at room temperature for 120 min without and with 68Ga-DPD-Fe3O4 at concentrations 0.1 and 1.0 mg/ml. Optical microscopy (OM) and atomic force microscopy (AFM) are employed to assess detailed information on the overall morphological and geometrical characteristics of the entire cell at the microscopic (10−6 m) level and on the membrane morphology at the nanoscopic (10−9 m) level. In addition, a standard hematology analyzer (HA) is used to obtain complete blood count information. At the microscopic level, the combined OM, AFM and HA data revealed that the overall shape/size characteristics of RBCs were preserved upon incubation with 68Ga-DPD-Fe3O4. However, at the nanoscopic level, the AFM results revealed two different kinds of local deconstructions of the RBCs membrane, termed holes and ulcer-like abnormalities, that were observed in both the DMCA-free and DMCA-incubated samples.

On the contrary, ulcer-like abnormalities exhibited two statistically significant differences upon incubation with the 68Ga-DPD-Fe3O4 DMCA. First, increased percentage of RBCs having at least one ulcer-like abnormality; in DMCA-incubated samples 78.6 ± 11.6% for CDMCA = 0.1 mg/ml and 80.4 ± 11.1% for CDMCA = 1.0 mg/ml, while in DMCA-free samples 61.2 ± 8.4% prior to and 63.6 ± 13.5% after incubation. Second, increased number of ulcer-like abnormalities per RBC; in DMCA-incubated samples 4.26 ± 0.62 for CDMCA = 0.1 mg/ml and 3.99 ± 0.97 for CDMCA = 1.0 mg/ml, while in DMCA-free samples 2.84 ± 0.54 prior to and 2.98 ± 0.50 after incubation. The combined OM, AFM and HA results prove fair hemocompatibility of the 68Ga-DPD-Fe3O4 DMCA with human RBCs, thus documenting its potential use in imaging applications.

abstract = "Dual-modality contrast agents (DMCA), such as radiolabeled magnetic nanoparticles, have attracted significant attention in diagnostic applications due to their potency for the timely and accurate diagnosis of diseases. The hemocompatibility of a candidate DMCA with human blood is essential for the investigation of its application in vivo. In this respect, here we focused on the evaluation of the hemocompatibility of a new DMCA, that is based on iron oxide nanoparticles (i.e. Fe3O4 magnetite), with human red blood cells (RBCs). The specific iron oxide nanoparticles are surface functionalized with 2,3-dicarboxypropane-1,1-diphosphonic acid (-DPD) and radiolabeled with gallium-68 (68Ga), resulting in 68Ga-DPD-Fe3O4. RBCs of five healthy individuals are incubated at room temperature for 120 min without and with 68Ga-DPD-Fe3O4 at concentrations 0.1 and 1.0 mg/ml. Optical microscopy (OM) and atomic force microscopy (AFM) are employed to assess detailed information on the overall morphological and geometrical characteristics of the entire cell at the microscopic (10−6 m) level and on the membrane morphology at the nanoscopic (10−9 m) level. In addition, a standard hematology analyzer (HA) is used to obtain complete blood count information. At the microscopic level, the combined OM, AFM and HA data revealed that the overall shape/size characteristics of RBCs were preserved upon incubation with 68Ga-DPD-Fe3O4. However, at the nanoscopic level, the AFM results revealed two different kinds of local deconstructions of the RBCs membrane, termed holes and ulcer-like abnormalities, that were observed in both the DMCA-free and DMCA-incubated samples. Holes did not exhibit any statistically significant difference upon incubation with the 68Ga-DPD-Fe3O4 DMCA. On the contrary, ulcer-like abnormalities exhibited two statistically significant differences upon incubation with the 68Ga-DPD-Fe3O4 DMCA. First, increased percentage of RBCs having at least one ulcer-like abnormality; in DMCA-incubated samples 78.6 ± 11.6% for CDMCA = 0.1 mg/ml and 80.4 ± 11.1% for CDMCA = 1.0 mg/ml, while in DMCA-free samples 61.2 ± 8.4% prior to and 63.6 ± 13.5% after incubation.

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  - 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  - 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 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.

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  - Magnetic nanoparticle (MNP)-mediated hyperthermia (MH) coupled with radiation therapy (RT) is a novel approach that has the potential to overcome various practical difficulties encountered in cancer treatment. In this work, we present recommendations for the in vitro and in vivo testing and application of the two treatment techniques. These recommendations were developed by the members of Working Group 3 of COST Action TD 1402: Multifunctional Nanoparticles for Magnetic Hyperthermia and Indirect Radiation Therapy (“Radiomag”). The purpose of the recommendations is not to provide definitive answers and directions but, rather, to outline those tests and considerations that a researcher must address in order to perform in vitro and in vivo studies. The recommendations are divided into 5 parts: (a) in vitro evaluation of MNPs; (b) in vitro evaluation of MNP-cell interactions; (c) in vivo evaluation of the MNPs; (d) MH combined with RT; and (e) pharmacokinetic studies of MNPs. Synthesis and characterization of the MNPs, as well as RT protocols, are beyond the scope of this work.

AB  - Nuclear medicine is a branch of medicine that uses radiation to provide infor¬mation about the functioning of a person’s specific tissue/organs or to treat a disease. Radiolabeled nanoparticles (NPs) represent a new class of agents with a great potential for nuclear medicine applications. The key advantage of using radiolabeled NPs is that a very small amount can be used to obtain information of great importance.1 They may be used to detect and characterize disease, to deliver relevant therapeutics, and to monitor the therapeutic effect as well. Furthermore radiotracer-based imaging either using single-photon emission computed tomog¬raphy (SPECT) or positron emission tomography (PET) is particularly suited in the study of pharmacokinetic/pharmacodynamic parameters of nanomaterials and determination of their optimal nanodimensional architecture for tissue/organ re¬generation. Measuring radiation from radioactive tracers attached to NPs has been demonstrated to be a highly sensitive and specific method that allows accurate quantification, without limits to tissue penetration in any organ. Nuclear imaging approaches are highly suitable for detection, as they offer a high detection sensitiv¬ity at high temporal and spatial resolutions, requiring a radionuclide concentration of around 10−10 M at the site of interest.Nanoparticulate agents typically demonstrate pharmacokinetic behavior differ¬ent from that of small molecules2 and provide flexible platforms for integration of multiple functional entities, including targeting ligands, multiple types of contrast materials, and/or therapeutics. In contrast to traditional compounds used for radio¬pharmaceutical preparation, nanomaterials have an immense available surface area per unit of volume and tunable optical, electronic, magnetic, and biological proper¬ties. Generally, they can be tailored to meet the needs of specific applications and engineered to have different physicochemical properties that affect in vivo biodis¬tribution: sizes, shapes, chemical compositions, surface chemical characteristics, and hollow or solid structures.3 Efficient diagnosis/radiotherapy is provided through passive targeting based on the enhanced permeability and retention (EPR) effect and/or active targeting through the incorporation of a targeting moiety on an NP. Nontargeted NPs can accumulate in tumors, as the tumor vasculature is usually leaky and without lymphatic drainage. Active targeting is achieved by functionalizing the NPs surface with suitable vectors, including peptides, antibodies, and other biomolecules, which recognize characteristic epitopes at the surface of the diseased cells.Radiolabeled antibodies may effectively target even single cancer cells in circula¬tion5 or small cancer cell clusters,6 thereby enabling a more specific radiation dose delivery, preventing damage to healthy tissues.

The key advantage of using radiolabeled NPs is that a very small amount can be used to obtain information of great importance.1 They may be used to detect and characterize disease, to deliver relevant therapeutics, and to monitor the therapeutic effect as well. Furthermore radiotracer-based imaging either using single-photon emission computed tomog¬raphy (SPECT) or positron emission tomography (PET) is particularly suited in the study of pharmacokinetic/pharmacodynamic parameters of nanomaterials and determination of their optimal nanodimensional architecture for tissue/organ re¬generation. Measuring radiation from radioactive tracers attached to NPs has been demonstrated to be a highly sensitive and specific method that allows accurate quantification, without limits to tissue penetration in any organ. Nuclear imaging approaches are highly suitable for detection, as they offer a high detection sensitiv¬ity at high temporal and spatial resolutions, requiring a radionuclide concentration of around 10−10 M at the site of interest.Nanoparticulate agents typically demonstrate pharmacokinetic behavior differ¬ent from that of small molecules2 and provide flexible platforms for integration of multiple functional entities, including targeting ligands, multiple types of contrast materials, and/or therapeutics. In contrast to traditional compounds used for radio¬pharmaceutical preparation, nanomaterials have an immense available surface area per unit of volume and tunable optical, electronic, magnetic, and biological proper¬ties. Generally, they can be tailored to meet the needs of specific applications and engineered to have different physicochemical properties that affect in vivo biodis¬tribution: sizes, shapes, chemical compositions, surface chemical characteristics, and hollow or solid structures.3 Efficient diagnosis/radiotherapy is provided through passive targeting based on the enhanced permeability and retention (EPR) effect and/or active targeting through the incorporation of a targeting moiety on an NP. Nontargeted NPs can accumulate in tumors, as the tumor vasculature is usually leaky and without lymphatic drainage. Active targeting is achieved by functionalizing the NPs surface with suitable vectors, including peptides, antibodies, and other biomolecules, which recognize characteristic epitopes at the surface of the diseased cells.Radiolabeled antibodies may effectively target even single cancer cells in circula¬tion5 or small cancer cell clusters,6 thereby enabling a more specific radiation dose delivery, preventing damage to healthy tissues.",

AB  - Thirty days before expected time of parturition, 20 Holstein cows were divided into −Cr and +Cr groups. From day 25 before parturition (BP) up to day 30 after parturition (AP), +Cr cows received 10 mg of Cr (chromium-enriched yeast) daily. Muscle and adipose tissue samples were taken at days −30, −10, +7 and +10 related to parturition, when body condition score (BCS) was also determined. Hepatic tissue samples were taken at days −10 and +7. Tissue samples were used for determination of the insulin signalling pathway protein expressions. Intravenous glucose tolerance test (IVGTT) was performed at days −28, −7, +10 and +30. Milk yield was recorded during first 14 weeks AP. Milk composition was obtained at days 7 and 28 AP. At day 10 BP, protein content of β-subunit of insulin receptor (IRβ) was significantly higher (p ˂ 0.05) in muscle, and phosphorylation of insulin receptor substrate 1 at serine 307 (pIRS-1 Ser307) was significantly lower (p ˂ 0.05) in hepatic tissue of +Cr group. After parturition, pIRS-1 Ser307 was significantly lower in muscle tissue at days 7 and 28 (p ˂ 0.05 and p ˂ 0.001, respectively), while phosphorylation of Akt at serine 473 (pAkt Ser473) was significantly higher (p ˂ 0.01) in hepatic tissue at day 7 AP in +Cr group. Chromium had opposite effect on insulin kinetics during IVGTTs obtained BP and AP. Insulin secretion was significantly reduced at day 7 BP and significantly enhanced at day 10 AP, when NEFA concentration was also significantly increased. Milk yield and ECM value were depressed in +Cr group. DMI and BCS were significantly enhanced in +Cr group at day 7 BP. In conclusion, chromium modulates insulin signalling pathway in dairy cows, but targeted signalling molecules are different in antepartal then post-partal period, probably due to duration of exposure to chromium and different energy status between those periods.

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  - Magnetic nanoparticles (MNPs) are of immense interest for diagnostic and therapeutic applications in medicine. Design and development of new iron oxide-based MNPs for such applications is of rather limited breadth without reliable and sensitive methods to determine their levels in body tissues. Commonly used methods, such as ICP, are quite problematic, due to the inability to decipher the origin of the detected iron, i.e. whether it originates from the MNPs or endogenous from tissues and bodily fluids. One of the approaches to overcome this problem and to increase reliability of tracing MNPs is to partially substitute iron ions in the MNPs with Er. Here, we report on the development of citric add coated (Fe,Er)(3)O-4 nanopartides and characterization of their physico-chemical and biological properties by utilization of various complementary approaches. The synthesized MNPs had a narrow (6-7 nm) size distribution, as consistently seen in atomic pair distribution function, transmission electron microscopy, and DC magnetization measurements. The particles were found to be superparamagnetic, with a pronounced maximum in measured zero-field cooled magnetization at around 90 K. Reduction in saturation magnetization due to incorporation of 1.7% Er3+ into the Fe3O4 matrix was clearly observed. From the biological standpoint, citric acid coated (Fe,Er)(3)O-4 NPs were found to induce low toxicity both in human cell fibroblasts and in zebrafish (Danio rerio) embryos. Biodistribution pattern of the MNPs after intravenous administration in healthy Wistar rats was followed by the radiotracer method, revealing that Y-90-labeled MNPs were predominantly found in liver (7533% ID), followed by lungs (16.70% ID) and spleen (2.83% ID). Quantitative agreement with these observations was obtained by ICP-MS elemental analysis using Er as the detected tracer. Based on the favorable physical, chemical and biological characteristics, citric add coated (Fe,Er)(3)O-4 MNPs could be further considered for the potential application as a diagnostic and/or therapeutic agent. This work also demonstrates that combined application of these techniques is a promising tool for studies of pharmacokinetics of the new MNPs in complex biological systems. (C) 2017 Elsevier B.V.

The particles were found to be superparamagnetic, with a pronounced maximum in measured zero-field cooled magnetization at around 90 K. Reduction in saturation magnetization due to incorporation of 1.7% Er3+ into the Fe3O4 matrix was clearly observed. From the biological standpoint, citric acid coated (Fe,Er)(3)O-4 NPs were found to induce low toxicity both in human cell fibroblasts and in zebrafish (Danio rerio) embryos. Biodistribution pattern of the MNPs after intravenous administration in healthy Wistar rats was followed by the radiotracer method, revealing that Y-90-labeled MNPs were predominantly found in liver (7533% ID), followed by lungs (16.70% ID) and spleen (2.83% ID). Quantitative agreement with these observations was obtained by ICP-MS elemental analysis using Er as the detected tracer. Based on the favorable physical, chemical and biological characteristics, citric add coated (Fe,Er)(3)O-4 MNPs could be further considered for the potential application as a diagnostic and/or therapeutic agent. This work also demonstrates that combined application of these techniques is a promising tool for studies of pharmacokinetics of the new MNPs in complex biological systems. (C) 2017 Elsevier B.V.
