AB  - Resurrection plant Ramonda serbica Panc. survives desiccation for a long period and fully recovers metabolic functions already within one day upon watering [1]. Besides osmotic stress, desiccation provokes the accelerated generation of reactive oxygen species. The aim of our study was obtaining more insight into the mechanisms of desiccation tolerance in R. serbica by TMT labelled comparative quantitative proteomics of hydrated (HL) and desiccated leaves (DL). After de novo transcriptome analysis, 189456 transcripts with 189003 unigenes were annotated with seven common databases. Proteomic analysis allowed for the relative quantification of 895 different protein groups, 321 with a statistically significant difference in abundance between FL and DL. Among them, 25% referred to chloroplast and almost the same percentage were associated with desiccation and oxidative stress. Almost all differentially abundant proteins related to photosynthetic processes were down-regulated in DL, while those required for protein translation were more abundant in HL. Within differentially abundant proteins involved in antioxidative defence, the levels of enzymes involved in ascorbate-glutathione cycle, peroxiredoxins, Fe and Mn superoxide dismutase (SOD) were all reduced in DL, while germin-like proteins, three Cu/Zn SOD isoforms and polyphenol oxidases were more abundant in DL compared with HL. The protein family with the highest number of members showing the greatest accumulation upon desiccation comprised twenty different late embryogenesis abundant proteins (LEAPs), similarly as found by differential transcriptomic analysis. Taken together, our results imply a key role of LEAPs and Cu/Zn SOD in protective mechanism against desiccation in R. serbica, that may have significant implications on drought-related studies of crops grown in arid areas. This work was supported by the Science Fund of the Republic of Serbia (PROMIS project LEAPSyn-SCI, grant number 6039663). M.V. wishes to acknowledge the support of COST Action BM1405 for approving STSM in Padua during 2017 and 2018.

AB  - A method using modified QuEChERS (Quick, Easy, Cheap, Effective, Rugged, Safe) without clean-up step based on the sample dilution approach followed by the liquid chromatography coupled with the tandem mass spectrometry (LC-MS/MS) has been established for determination of 179 pesticide residues in cabbage and rice samples. Two different LC columns were used and their sensitivity was investigated regarding the sample volume. Evaluation of the matrix effect in context of sample dilution and applied extraction solvents was investigated. The method was validated according to Document SANTE/12682/2019. For cabbage samples, recoveries were 70–120% for concentration level of 5 μg/kg; and 70–115% for concentration level of 50 μg/kg; precision RSDr <17%; limits of detection and quantification were in the ranges of 0.4–5.5 and 1.2–16.7 μg/kg, respectively. For rice samples, recoveries were 70–109% for 10 μg/kg concentration; 70–115% for 100 μg/kg concentration; precision RSDr <14%, while limits of detection and quantification were in the ranges of 0.5–4.2 and 1.5–12.7 μg/kg, respectively.

AB  - Polyethylene terephthalate (PET) is widely used material and as such became highly enriched in nature. It is generally considered inert and safe plastic, but due to the recent increased efforts to break-down PET using biotechnological approaches, we realized the scarcity of information about structural analysis of possible degradation products and their ecotoxicological assessment. Therefore, in this study, 11 compounds belonging to the group of PET precursors and possible degradation products have been comprehensively characterized. Seven of these compounds including 1-(2-hydroxyethyl)-4-methylterephthalate, ethylene glycol bis(methyl terephthalate), methyl bis(2-hydroxyethyl terephtahalate), 1,4-benzenedicarboxylic acid, 1,4-bis[2-[[4-(methoxycarbonyl)benzoyl]oxy]ethyl] ester and methyl tris(2-hydroxyethyl terephthalate) corresponding to mono-, 1.5-, di-, 2,5- and trimer of PET were synthetized and structurally characterized for the first time. In-silico druglikeness and physico-chemical properties of these compounds were predicted using variety of platforms. No antimicrobial properties were detected even at 1000 μg/mL. Ecotoxicological impact of the compounds against marine bacteria Allivibrio fischeri proved that the 6 out of 11 tested PET-associated compounds may be classified as harmful to aquatic microorganisms, with PET trimer being one of the most toxic. In comparison, most of the compounds were not toxic on human lung fibroblasts (MRC-5) at 200 μg/mL with inhibiting concentration (IC50) values of 30 μg/mL and 50 μg/mL determined for PET dimer and trimer. Only three of these compounds including PET monomer were toxic to nematode Caenorhabditis elegans at high concentration of 500 μg/mL. In terms of the applicative potential, PET dimer can be used as suitable substrate for the screening, identification and characterization of novel PET-depolymerizing enzymes.

AB  - Non-covalent selenium–selenium interactions between selenium-containing organic molecules were studied in crystal structures from the Cambridge Structural Database and by high-level quantum chemical calculations. Se⋯Se contacts in the crystal structures were analyzed, and the most frequent patterns were identified and used to design the model systems for quantum chemical calculations. The strongest calculated Se⋯Se interaction (ΔECCSD(T)/CBS = −2.31 kcal mol−1) was identified in the model system with a mutual parallel orientation of interacting molecules. In the crystal structures, this orientation of molecules is predominant. In the geometry with the σ-hole bonding, the interaction is somewhat weaker (ΔECCSD(T)/CBS = −2.13 kcal mol−1). NCI analysis showed that Se⋯Se interaction in the most stable geometries is further enhanced by hydrogen bonding of Se–H⋯Se or C–H⋯Se type. The results of energy decomposition analysis (SAPT) calculations revealed that the nature of the Se⋯Se interaction is predominantly dispersive with a strong electrostatic contribution. The results of the energy decomposition analysis also suggest that the electrostatic component has a crucial role in defining the geometry of selenium–selenium interactions due to their directional nature.

AB  - Background: Diazepam belongs to the group of 1,4-benzodiapines. It is used for the treatment of anxiety, convulsions and as a muscle relaxant. The presence of 4,5-azomethine group enables its electrochemical detection.

Introduction: A screen-printed electrode modified with antimony film was used for the determination of diazepam in pharmaceutical preparations

Methods: Electrode modification was done by ex-situ deposition of antimony on commercially available screen-printed electrode. Parameters affecting the electroanalytical response of the sensor, such as deposition potential, deposition time, and antimony concentration, were examined and optimized. The modified electrode showed enhanced electroactivity for diazepam reduction compared to unmodified electrode. Under optimal conditions, linear sweep voltammetry was used for the determination of analyte.

Results: The sensor showed linear dependence in the range from 0.5 to 10 μmol/L, the correlation coefficient was 0.9992. The limit of detection was 0.33 μmol/L, corresponding limit of quantification was 1.08 μmol/L. Modification enabled determination of diazepam in the presence of oxygen. 

Conclusion: The modified electrode was used for the determination of diazepam in tablets. Results confirmed the applicability of the electrochemical sensor.

AB  - The electrochemical characterization of sertraline at gold electrode was examined by cyclic voltammetry measurements (CV) in pH 8.4 bicarbonate buffer. Then Au electrode was evaluated for the quantitative determination of sertraline using square wave voltammetry (SWV). To enhance the sensitivity during the drug determination, (2-hydroxypropyl)-β-cyclodextrin (HPβCD) and β-cyclodextrin (βCD) inclusion complexes were employed. Using the proposed SWV technique, the anodic current peak was linear within a concentration range of 0.1–0.5 µM with a limit of detection (LOD) of 2.0 × 10–8 M and a limit of quantification (LOQ) of 6.7 × 10–8 M. In the case of inclusion complex of the sertraline with HPβCD, a good linearity range of 0.1–0.9 µM was obtained with a LOD of 2.6 × 10–8 M and a LOQ of 8.8 × 10–8 M. The gold electrode revealed the same linearity range for inclusion complex of the sertraline with βCD with a LOD and a LOQ being 2.6 × 10–8 and 8.6 × 10–8 M, respectively. Comparing the regression equations, it can be concluded that the sensitivity in the presence of inclusion complex can be up to 5 times higher. The applicability of the developed method was confirmed by the analysis of this drug in pharmaceutical formulation and in human serum spiked with sertraline standard. The comparison to HPLC method was successfully performed.

AB  - The light-transmitting measurements at the 655 nm wavelength have been performed through starch-coated cobalt ferrite ferrofluids synthesized by well-established synthetic methods, i.e., coprecipitation, mechanochemical, ultrasonically assisted coprecipitation, microemulsion, and microwave-assisted hydrothermal syntheses, exposed to an external magnetic field of 200–400 mT. The investigated samples can be divided into the two groups. The first is where the samples showed higher rate of agglomeration and sedimentation effects. The group of samples synthesized by microemulsion, microwave-assisted hydrothermal method, and mechanochemical method showed less pronounced rate of chain formation. Such measurements present good method for the preliminary selection of possible magnetic resonance imaging (MRI) contrast agents between differently synthesized ferrite suspensions.

AB  - Electronic interactions in donor-π-linker-acceptor systems with barbituric acid as an electron acceptor and possible electron donor were investigated to screen promising candidates with a push–pull character based on experimental and quantum chemical studies. The tautomeric properties of 5-benzylidenebarbituric acid derivatives were studied with NMR spectra, spectrophotometric determination of the pKa values, and quantum chemical calculations. Linear solvation energy relationships (LSER) and linear free energy relationships (LFER) were applied to the spectral data - UV frequencies and 13C NMR chemical shifts. The experimental studies of the nature of the ground and excited state of investigated compounds were successfully interpreted using a computational chemistry approach including ab initio MP2 geometry optimization and time-dependent DFT calculations of excited states. Quantification of the push–pull character of barbituric acid derivatives was performed by the 13CNMR chemical shift differences, Mayer π bond order analysis, hole-electron distribution analysis, and calculations of intramolecular charge transfer (ICT) indices. The results obtained show, that when coupled with a strong electron-donor, barbituric acid can act as the electron-acceptor in push–pull systems, and when coupled with a strong electron-acceptor, barbituric acid can act as the weak electron-donor.

AB  - High amounts of toxic textile dyes are released into the environment due to coloring and wastewaters treatment processes' inefficiency. To remove dyes from the environment and wastewaters, researchers focused on applying immobilized enzymes due to mild reaction conditions and enzyme nontoxicity. Laccases are oxidases with wide substrate specificity, capable of degradation of many different dye types. Laccase from Streptomyces cyaneus was expressed on the surface of Saccharomyces cerevisiae EBY100 cells. The specific activity of surface-displayed laccase was increased by toluene-induced lysis to 3.1 U/g of cell walls. For cell wall laccase immobilization within hydrogel beads, alginate was modified by dopamine using periodate oxidation and reductive amination and characterized by UV–Vis, FTIR, and NMR spectroscopy. Cell wall laccase was immobilized within alginate and dopamine-alginate beads additionally cross-linked by oxygen and laccase. The immobilized enzyme's specific activity was two times higher using dopamine-alginate compared to native alginate beads, and immobilization yield increased 16 times. Cell wall laccase immobilized within dopamine-alginate beads decolorized Amido Black 10B, Reactive Black 5, Evans Blue, and Remazol Brilliant Blue with 100% efficiency and after ten rounds of multiple-use retained decolorization efficiency of 90% with Evans Blue and 61% with Amido Black.

AB  - The aim of research was to determine polyphenols bioaccessibility and antioxidant properties of thermally-treated skimmed goat milk enriched with sunflower bee-collected pollen through in vitro digestion. HPLC analysis confirmed that pollen-enriched milk contained flavonols as the main phenolic fraction (80.7–76.2%) followed by phenolic acids (14.2–17.4%). Among individual compounds quercetin-3-O-glucoside (155.1–197.2 μg/L) and p-coumaric acid (29.5–30.7 μg/L) were the main quantified flavonols and phenolic acids, respectively. After digestion of milk/pollen sample, total polyphenols recovery was 30.71% with higher phenolic acids recovery (40.1%) compared to flavonols (28.3%) indicating strong interactions between caprine milk casein micelles and pollen polyphenols. Applied antioxidant assays (phosphomolybdenum, ABTS•+scavenging activity and ferrous-ion-chelating capacity) have confirmed complexity of prepared product- it had high ability to quench ABTS•+ radicals and to form chelating complexes with Fe2+ ions. Digestion provoked 20% reduction in total antioxidant capacity compared to the initial sample. TTSG milk/pollen powder could be good functional ingredient. © 2021 Elsevier Ltd

AB  - Helichrysum italicum (Roth) G. Don fil., Asteraceae, possesses numerous secondary plant metabolites with a wide range of biological activities. Yet, data on the potential of supercritical fluid extraction (SFE) in their isolation are scarce. This study provides analyses of the chemical profiles of extracts obtained by SFE with or without ethanol as a cosolvent using GC-FID, GC-MS, HPLC, and UHPLC-MS techniques. Among the compounds with proven biological activity identified, the presence of arzanol was confirmed. In the next step, the integrated process of supercritical fluid extraction and impregnation was applied to deliver active compounds to cotton gauze and polypropylene fabric for possible topical applications. The analytical procedures results showed a considerable affinity of both textile materials for incorporating active components present in the H. italicum. The study indicated the high-pressure techniques applied as very efficient in the isolation of bioactive components from H. italicum and their adsorption on selected carriers.

AB  - Different Schiff base complexes have biological activities that make them suitable for drug design. The biological properties of tetradentate Schiff base copper(II) complexed with N,N′-bis(acetylacetone)propylenediimine have been studied. The cytotoxic activity towards Caco-2 cells were determined by MTT, Anexin V and PI apoptosis assays. N,N′-bis(acetylacetone)propylenediimine-copper(II) showed the anti-cancer and anti-proliferative properties by inducing apoptosis in Caco-2 cells. A comparison of the cytotoxic activity of this compound with cisplatin shows that it is more effective on the colorectal cancer cell line Caco-2. The binding capacity and interaction of N,N′-bis(acetylacetone)propylenediimine-copper(II) with HSA were systemically investigated by in vitro fluorescence spectroscopy, CD spectroscopy, and in silico molecular docking study. Furthermore, in vitro and in silico interaction studies indicated that the complex binds to HSA through a static quenching mechanism without changes in protein conformation. The calculated number of binding sites was in line with molecular docking studies. The obtained Ka value suggests that the compound can be released from the protein in target cells. The tetradentate Schiff base copper(II) complex exhibited in vitro biological activities against cancer epithelial cells, which depend on the molecular structure of the complex, causing apoptosis, and the complex can bind to the protein drug carrier in circulation to the target tissue.

AB  - Background: Diazepam belongs to the group of 1,4-benzodiapines. It is used for the treatment of anxiety, convulsions and as a muscle relaxant. The presence of 4,5-azomethine group enables its electrochemical detection.Introduction: A screen-printed electrode modified with antimony film was used for the determination of diazepam in pharmaceutical preparationsMethods: Electrode modification was done by ex-situ deposition of antimony on commercially available screen-printed electrode. Parameters affecting the electroanalytical response of the sensor, such as deposition potential, deposition time, and antimony concentration, were examined and optimized. The modified electrode showed enhanced electroactivity for diazepam reduction compared to unmodified electrode. Under optimal conditions, linear sweep voltammetry was used for the determination of analyte.Results: The sensor showed linear dependence in the range from 0.5 to 10 μmol/L, the correlation coefficient was 0.9992. The limit of detection was 0.33 μmol/L, corresponding limit of quantification was 1.08 μmol/L. Modification enabled determination of diazepam in the presence of oxygen. Conclusion: The modified electrode was used for the determination of diazepam in tablets. Results confirmed the applicability of the electrochemical sensor.

AB  - Lipids play an essential role in platelet functions. It is known that polyunsaturated fatty acids play a role in increasing platelet reactivity and that the prothrombotic phenotype plays a crucial role in the occurrence of major adverse cardiovascular events. The ongoing increase in cardiovascular diseases’ incidence emphasizes the importance of research linking lipids and platelet function. In particular, the rebound phenomenon that accompanies discontinuation of clopidogrel in patients receiving dual antiplatelet therapy has been associated with changes in the lipid profile. Our many years of research underline the importance of reduced HDL values for the risk of such a rebound effect and the occurrence of thromboembolic events. Lipids are otherwise a heterogeneous group of molecules, and their signaling molecules are not deposited but formed “on-demand” in the cell. On the other hand, exosomes transmit lipid signals between cells, and the profile of such changes can be monitored by lipidomics. Changes in the lipid profile are organ-specific and may indicate new drug action targets.

AB  - BACKGROUND: Pectin is a complex polysaccharide, present in fresh and processed food as an additive, which also serves as an important source of fiber. In this work, the aim was to investigate in-vitro application of apple pectin as a possible antimicrobial, antioxidant and prebiotic agent for growth of bacteria selected from human milk and infant feces, as well as standard strains Lactobacillus rhamnosus and Bifidobacterium bifidum.
METHODS : All the bacteria isolated from the milk of mothers of preterm and term-born infants, bacteria from infant feces and standard strains were tested for fermentation of apple pectin as the main carbohydrate in selective broth media.
RESULTS: An increase in the growth of bacteria Bifidobacteria, Lactobacillus, and a consortium of bacteria selected from human milk and infant feces was noticed after pectin fermentation. It was found that pectin has a positive impact on the increase of the antioxidant capacity in all the tested samples. A high correlation was achieved, comparing electrochemical with spectrophotometric methods. Antimicrobial tests showed that pectin and fermentation products have slight or no influence at all on the growth of standard strains of Escherichia coli, Staphylococcus aureus and Candida albicans.
CONCLUSIONS: The results showed the importance of pectin as an antioxidant and its impact on the development of potential probiotic microbiota in mothers and infants. The study indicated a new potential application of pectin as a supplement in infant food.

AB  - Polyethylene terephthalate (PET) is widely used material and as such became highly enriched in nature. It is generally considered inert and safe plastic, but due to the recent increased efforts to break-down PET using biotechnological approaches, we realized the scarcity of information about structural analysis of possible degradation products and their ecotoxicological assessment. Therefore, in this study, 11 compounds belonging to the group of PET precursors and possible degradation products have been comprehensively characterized. Seven of these compounds including 1-(2-hydroxyethyl)-4-methylterephthalate, ethylene glycol bis(methyl terephthalate), methyl bis(2-hydroxyethyl terephtahalate), 1,4-benzenedicarboxylic acid, 1,4-bis[2-[[4-(methoxycarbonyl)benzoyl]oxy]ethyl] ester and methyl tris(2-hydroxyethyl terephthalate) corresponding to mono-, 1.5-, di-, 2,5- and trimer of PET were synthetized and structurally characterized for the first time. In-silico druglikeness and physico-chemical properties of these compounds were predicted using variety of platforms. No antimicrobial properties were detected even at 1000 μg/mL. Ecotoxicological impact of the compounds against marine bacteria Allivibrio fischeri proved that the 6 out of 11 tested PET-associated compounds may be classified as harmful to aquatic microorganisms, with PET trimer being one of the most toxic. In comparison, most of the compounds were not toxic on human lung fibroblasts (MRC-5) at 200 μg/mL with inhibiting concentration (IC50) values of 30 μg/mL and 50 μg/mL determined for PET dimer and trimer. Only three of these compounds including PET monomer were toxic to nematode Caenorhabditis elegans at high concentration of 500 μg/mL. In terms of the applicative potential, PET dimer can be used as suitable substrate for the screening, identification and characterization of novel PET-depolymerizing enzymes.

AB  - Pure and Cr-doped hematite (α-(Fe1-xCrx)2O3, x = 0, 0.026, 0.039, 0.085 or 0.135) nanorods were prepared by a simple co-precipitation and calcination method. Influence of different levels of Cr doping on the change of properties of long and thin pure hematite nanorods was investigated. Cr3+-for-Fe3+ substitution in the crystal structure of hematite was proved by measuring a gradual contraction of the unit cell and a gradual decrease of the hyperfine magnetic field by increasing the Cr molar fraction. Cr doping induced an increase in the width and thickness of hematite nanorods, as well as a decrease in the overall surface area. Low temperature 57Fe Mössbauer spectroscopy showed that the Morin transition in hematite was suppressed by Cr doping to temperatures below 80 K. Magnetic measurements confirmed the suppression of the Morin transition in Cr-doped hematite down to 5 K. Infrared spectra of Cr-doped hematite samples showed shifts of IR bands by Cr3+-for-Fe3+ substitution. Optical properties of α-Fe2O3 nanorods changed significantly by Cr doping – the absorption edge was shifted to higher wavelengths, accompanied by a greater absorption in the visible range and narrowed direct and indirect optical band gaps. The improved visible light photocatalytic activity of hematite nanorods in the heterogeneous photo-Fenton process by moderate Cr doping was measured, which can be attributed to the modifications in electronic structure and optical properties.

Kvantifikacija selena u uzorcima tkiva vrste Rattus norvegicus suplementirane nano-selenom

AB  - Selen je mikroelement od velikog značaja za ljudsko zdravlje. Ima ulogu u biološkim procesima poput inhibiranja procesa apoptoze, pravilnog funkcionisanja imunskog sistema i drugih. Brojne studije pokazale su da nedostatak ovog elementa može biti povezan sa kardiovaskularnim poremećajima, određenim tipovima malignih oboljenja, degeneracijom hrskavice zgloba (disk), disfunkcijom štitaste žlezde i drugih. Takođe je utvrđeno da nedostatak selena može negativno uticati na razvoj embriona.
Mnoge studije su pokazale da jedinjenja selena mogu biti toksična. Toksičnost selena ne zavisi samo od unete količine, već i od njegovog hemijskog oblika. Studije na životinjama pokazale su da je neorganski selen otrovniji od selenata i elementarnog selena. Uticaj toksičnosti određenih elemenata se ispituje na životinjama. U laboratorijama se najčešće koriste miševi i pacovi kao modeli životinja za biomedicinska istraživanja. Oni imaju dosta sličnosti sa ljudima u pogledu anatomije i fiziologije. Pacovi, miševi i ljudi imaju otprilike oko 30,000 gena, a od toga oko 95% su zajednički za sve tri vrste.
Nano-selen predstavlja elementarni selen, oksidacionog stanja 0, koji je reda veličine 20-60 nm. Nano-selen privlači dosta pažnje zahvaljujući visokoj bioraspoloživosti i nižoj toksičnosti u odnosu na druge oblike Se. Koristi se kao sredstvo za hemoprevenciju, kao antioksidans i dr. Cilj ovog rada bio je kvantifikacija akumuliranog selena u različitim uzorcima solidnih tkiva i krvi odraslih ženki miševa vrste Rattus norvegicus i transplacentalnog prelaza na tkivo fetusa.
