AB  - Due to the similar chemical properties of Ni2+ and Co2+, several dozens of adsorptive stripping voltammetric (AdSV) methods have been developed for their simultaneous determination. The question was would there be some benefits if a stripping method made for simultaneous determination of Ni2+ and Co2+ will be optimized for the determination of only one of them (Ni2+). It was found that the optimized method has for an order of magnitude lower LOQ (1.89×10−10 M), an order of magnitude lower influence of Co2+, and the applicability of one calibration line for four orders of magnitude of Ni2+ concentration. The influence of some common anions and cations has been examined. The developed method was successfully applied for nickel content determination in real samples. The suitability of the developed method for the determination of Co2+ from the same solution in the second run, upon optimizations of deposition potential and time, was also explored. The LOQ obtained for Co2+ (3.61×10−11 M) is almost two orders of magnitude lower than LOQ of the method for simultaneous determination of both cations and, its LOD and LOQ are among few lowest obtained by AdSV methods for Co2+ determination. The developed method for Ni2+ and Co2+ determination from the same solution in two successive runs has significantly better analytical performances than the starting method for their simultaneous determination in one run.

AB  - We present the green, highly atom-economical, solid-state silica gel-catalyzed synthesis of polysubstituted 1,4- and 1,2-dihydropyridines (DHPs) from commercially available materials, amines and ethyl propiolate. The DHP skeleton was assembled by heating the reactants and silica gel in a closed vessel. Aliphatic amines provided 1,4-isomers as the main or only DHP products, but the reactions of aromatic amines yielded a mixture of 1,4- and 1,2-isomers. To the best of our knowledge, this is the first example of the formation of a 1,2-DHP structure by the reaction of an amine with propiolic ester. Addition of 1 mass percent of H2SO4 to silica gel shifted the product distribution to 1,4-DHP as the main or the only isomer obtained. Experimental and theoretical analyses led to the identification of two key intermediates en route to DHPs and the explanation of the observed regioisomeric ratios. 1,2-DHPs show blue-cyan fluorescence in MeOH with the quantum yield Φ = 0.10–0.22 relative to quinine sulfate Φ = 0.58 and 1,4-DHPs show blue-violet fluorescence with Φ = 0.09–0.81.

AB  - Heterocyclic pharmacophores such as thiazole and quinoline rings have a significant role in medicinal chemistry. They are considered privileged structures since they constitute several Food and Drug Administration (FDA)-approved drugs for cancer treatment. Herein, we report the synthesis, in silico evaluation of the ADMET profiles, and in vitro investigation of the anticancer activity of a series of novel thiazolyl-hydrazones based on the 8-quinoline (1a–c), 2-quinoline (2a–c), and 8-hydroxy-2-quinolyl moiety (3a–c). The panel of several human cancer cell lines and the nontumorigenic human embryonic kidney cell line HEK-293 were used to evaluate the compound-mediated in vitro anticancer activities, leading to [2-(2-(quinolyl-8-ol-2-ylmethylene)hydrazinyl)]-4-(4-methoxyphenyl)-1,3-thiazole (3c) as the most promising compound. The study revealed that 3c blocks the cell-cycle progression of a human colon cancer cell line (HCT-116) in the S phase and induces DNA double-strand breaks. Also, our findings demonstrate that 3c accumulates in lysosomes, ultimately leading to the cell death of the hepatocellular carcinoma cell line (Hep-G2) and HCT-116 cells, by the mechanism of autophagy inhibition.

AB  - Serotonin receptors modulate numerous behavioral and neuropsychological processes. Therefore, they are the target for the action of many drugs, such as antipsychotics, antidepressants, antiemetics, migraine remedies, and many others. The 5-HT1A receptors have been involved in the pathogenesis and treatment of anxiety and depression and represent a promising target for new drugs with reduced extrapyramidal side effects. In most antidepressants, a piperazine-based structural motif can be identified as a common moiety. Here we describe the synthesis, pharmacological, and in silico characterization of a novel arylpiperazines series with excellent 5-HT1A affinity. The final compounds, 4a, 8a, and 8b, were selected according to predictions of in silico pharmacokinetics, docking analysis, and molecular dynamics in conjunction with physical properties, and metabolic stability. The accentuated molecules could serve as a lead compound for developing 5-HT1A drug-like molecules for depression treatment.

AB  - In this study,we conducted a comprehensive investigation of newly synthesized fullerene derivatives developed for potential application in perovskite solar cells (PSCs). We explored three novel dihydrofuran-fused C60 fullerene derivatives (13, 14, and 15) that we respecifically designed to enhance solubility and interaction with the substrate, fluorine-dopedtinoxide (FTO). A comparative analysis was performed, with reference to the widely used phenyl-C61-butyric acid methyl ester (PCBM) and compound 12, from which 13, 14, and 15 are derived, to assess the impact of sugar units on materials properties.The synthesized compounds demonstrated significant solubility in common organic solvents, a critical factor in their potential application in wet-processed PSCs. Our investigation included electrochemical property analysis, thin film deposition, surface characterization, and electrochemical impedance spectroscopy (EIS). EIS measurements unveiled key in sights into charge transfer properties at the electrode/electrolyte interface, making the compounds attractive candidates for electron transport layers (ETLs) in PSCs.

AB  - The widespread abuse of traditional antibiotics has led to a global rise in antibiotic-resistant bacteria, which give in return unprecedented health risks. Therefore, there is a large and urgent need for the development of new, smart antibacterial agents able to efficiently kill or inhibit bacterial growth. In this study, we investigated the antibacterial activity of S, N-doped Graphene Quantum Dots (GQDs) as a light-triggered antibacterial agent. Gamma irradiation was employed as a tool to achieve one-step modification of GQDs in the presence of L-cysteine amino acid as a source of heteroatoms. X-ray Photoelectron Spectroscopy (XPS), nuclear magnetic resonance (NMR), and zeta potential measurements provided the necessary data to clarify the structure of modified dots and verify the introduction of both S- and N-atoms in GQDs structure, but also severe changes in the aromatic, sp2 domains. Namely, γ-irradiation caused a bonding of S atoms in 1.14 at.% mainly as thiol groups, and N in 1.81 at.% as amino groups, but sp2 contribution in GQD structure was lowered from 63.00 to 4.86 at.%, as measured in dots irradiated at a dose of 200 kGy. Fluorescence quenching measurements showed that L-cysteine-modified dots are able to bind to human serum albumin. The antibacterial activity of GQDs combined with 1 and 6 h of blue light (470 nm) irradiation was tested against 8 bacterial strains. GQD-cys-25 sample provided the best results, with minimum inhibitory concentration (MIC) as low as 125 μg/mL against S. aureus, E. faecalis, and E. coli after only 1 h of blue light exposure.

AB  - Banana allergy is often associated with the pollen and latex allergies, which led us to the  hypothesis that some yet unidentified banana allergen could provide a basis of the latex-pollen-fruit syndrome. S-adenosyl-L-homocysteine hydrolase (SAHH) was recently identified in the literature as a novel plant allergen. This study aimed to assess the allergenic potential of the naturally occurring banana SAHH (nSAHH) and its recombinant homolog produced in E. coli (rSAHH). nSAHH showed IgE reactivity with a serum pool of twelve banana-allergic persons,
while rSAHH displayed IgE reactivity in ten out of the twelve tested patients. Five linear B-cell epitopes were identified on the rSAHH surface, exhibiting ≥ 90 % sequence homology with relevant plant SAHH allergens. Our findings have elucidated SAHH as a novel plant panallergen, underlying the cross-reactivity between plant derived food and respiratory allergens, confirming our initial hypothesis.

AB  - Using quantum chemistry calculations and analysis of crystal structures from the
Cambridge Structural Database (CSD), three types of hydrogen bonds, NH/O, O1/HO
(hydrogen bond of a coordinated oxygen atom), and O2/HO (hydrogen bond of a noncoordinated oxygen atom) between different metal ion complexes of amino acids and a
free water molecule were studied. Octahedral cobalt(III) [1] and nickel(II), square
pyramidal copper(II), square planar copper(II), palladium(II), and platinum(II)
complexes were investigated at M06L-GD3/def2-TZVPP level, and interaction energies
were calculated using basis set superposition error (BSSE) corrected values. The NH/O
hydrogen bond of a doubly positive complex has an interaction energy of -16.9 kcal/mol.
For singly positive complexes, NH/O hydrogen bonds are weaker, from -8.3 to -12.1
kcal/mol strong, while for neutral complexes their values are the weakest, from -5.2 to -
7.2 kcal/mol. In neutral complexes with O1/HO, interaction energies are from -2.2 to -
5.1 kcal/mol, while interactions in singly negatively charged complexes are stronger,
from -6.9 to 8.2 kcal/mol. Neutral complexes also have weaker O2/HO hydrogen bonds,
from -3.7 to -5.0 kcal/mol, than the singly negatively charged systems, which have
interaction energy values from -8.0 to -9.0 kcal/mol. Therefore, the results of quantum
chemistry calculations showed that the strongest hydrogen bond is the NH/O, followed
by O1/HO, and lastly, O2/HO interaction. The results also show a strong influence of
the complex charge on the interaction energy. Other factors that influence the interaction
energy to a smaller extent are metal oxidation number, coordination number, and metal
atomic number. In the crystal structures from the CSD search, the d distributions for
copper(II) and cobalt(III) amino acid complexes are in good agreement with the quantum
chemistry results.

abstract = "Using quantum chemistry calculations and analysis of crystal structures from the
Cambridge Structural Database (CSD), three types of hydrogen bonds, NH/O, O1/HO
(hydrogen bond of a coordinated oxygen atom), and O2/HO (hydrogen bond of a noncoordinated oxygen atom) between different metal ion complexes of amino acids and a
free water molecule were studied. Octahedral cobalt(III) [1] and nickel(II), square
pyramidal copper(II), square planar copper(II), palladium(II), and platinum(II)
complexes were investigated at M06L-GD3/def2-TZVPP level, and interaction energies
were calculated using basis set superposition error (BSSE) corrected values. The NH/O
hydrogen bond of a doubly positive complex has an interaction energy of -16.9 kcal/mol.
For singly positive complexes, NH/O hydrogen bonds are weaker, from -8.3 to -12.1
kcal/mol strong, while for neutral complexes their values are the weakest, from -5.2 to -
7.2 kcal/mol. In neutral complexes with O1/HO, interaction energies are from -2.2 to -
5.1 kcal/mol, while interactions in singly negatively charged complexes are stronger,
from -6.9 to 8.2 kcal/mol. Neutral complexes also have weaker O2/HO hydrogen bonds,
from -3.7 to -5.0 kcal/mol, than the singly negatively charged systems, which have
interaction energy values from -8.0 to -9.0 kcal/mol. Therefore, the results of quantum
chemistry calculations showed that the strongest hydrogen bond is the NH/O, followed
by O1/HO, and lastly, O2/HO interaction. The results also show a strong influence of
the complex charge on the interaction energy. Other factors that influence the interaction
energy to a smaller extent are metal oxidation number, coordination number, and metal
atomic number. In the crystal structures from the CSD search, the d distributions for
copper(II) and cobalt(III) amino acid complexes are in good agreement with the quantum
chemistry results.",

of the high content of bioactive compounds such as dietary fiber, sugars, phenolic
compounds, and minerals. Plum production in Norway is located in the fjord districts of the
In most cases, levels of nutrients are altered by the genotype, cultivation techniques and preharvest
conditions. Therefore, the aim of this work was to investigate influence of
geographical and botanical origin on chemical composition of organic cultivated Norwegian
plum fruits. Besides aroma, fruit color and firmness, sugar content is one of the main traits
that influence fruit taste and one of the main benchmarks. A total of eight sugars and two
sugar alcohols were quantified in 30 investigated plum samples. The most abundant sugar in
all tested samples was glucose, followed by fructose and sucrose. Significant differences in
the content of sugars and sugar alcohols were found among the examined samples. In
investigated plum, 24 mineral elements were determined. Four macro-elements were
quantified in larger amounts: potassium, phosphorus, magnesium, and calcium. Dominant
mineral in all investigated plums was K (10922 45002 mg kg-1). The contents of toxic
elements (mercury, lead, arsenic, and cadmium) were below the limit of quantification
(allowable concentration). These findings could be useful as a reference for selecting the
plum and cultivar breeding for each location.

AB  - Honey is very complex natural substance consisted of sugars, water, and other compounds in smaller quantities such as proteins (enzymes), organic acids, vitamins, minerals, phenolics, and a large variety of volatile compounds. Discriminating the honeys according to botanical and/or geographical origin may be possible according to their characteristic constituents including organic acids profile. These acids are related to the colour and flavour of honey and its chemical properties such as acidity, pH and electrical conductivity. Honey is deceptively acidic, as the high sugar content tends to mask the acidity in the taste. Citric acid among other acids, is present in honey in moderate amount but it's presence could be potentially used as marker for authenticity control [1].

Fraudulent addition of compounds in honey sets a necesity to establish the natural level of the specific substances, and subsequently determine when this level is exceeded, indicating adulteration. Citric acid can be added to decrease pH in adulterated honey where normal pH levels have been exceeded. Also increased citrate concentration in honeys could be a result of addition of invert syrup to honey. Therefore there is a need for a method to determine citrate content in honey quickly and efficiently1. In current work a method for determination of organic acids profile in honey using ion chromatography with conductometric detection (IC-CD) without prior separation of compounds and chemical derivatization was developed. This approach for citric acid determination is characterized by LOD and LOQ values of 0.05 and 0.20 mg/L, respectively. Low RSD Sy/x value and r2 level of 0.9999 indicates a good regression model. Trueness of method was confirmed by good recoveries (108%, 104% and 95% for spiked levels 75%, 100% and 125%, respectively), while precision was confirmed by HorRat value (0.30) less than 2 [2].

AB  - Rhenium complexes merit particular attention in the area of metallodrug design due to
rhenium’s broad spectrum of oxidation states and consequently, the possibility to design
compounds of great structural diversity [1,2]. Thus, the synthesis, chemical characterization,
and antitumor activity in vitro of the six Re(V) complexes are described. Novel compounds
were obtained via reaction of [ReOCl3(PPh3)2] with corresponding ligands (pyridine-2-
carboxylic acid, 3-methylpyridine-2-carboxylic acid, 6-methylpyridine-2-carboxylic acid, 2,3-
pyridinedicarboxylic acid, 2,5-pyridinedicarboxylic acid, and 2,6-pyridinedicarboxylic acid) in
acetonitrile or dichloromethane/methanol at 78 °C for 3h. The complexes were fully
characterized using NMR, IR, MS, and elemental analysis. Results of X-ray diffraction analysis
for three of these compounds confirmed the proposed octahedral geometry with bidentate
coordinated ligands, via both oxygen and nitrogen atoms. The antiproliferative effect was
determined by MTT assay. All complexes expressed moderate to low cytotoxic potential.
Complex with pyridine-2-carboxylic acid showed dose-dependent cytotoxic potential,
particularly toward triple-negative breast adenocarcinoma cells MDA-MB-231 and pancreatic
adenocarcinoma cells PANC-1. Drug combination studies in PANC-1 cells with that complex
and Verapamil hydrochloride (VRP) showed a slight arrest of the cell cycle in the S phase and
also increase its antiproliferative potential.

extensively investigated as potential anticancer agents due to possibility of modulation of their
intracellular accumulation and respective anticancer mechanism of action [1,2]. In recent years
we have explored the anticancer activity of a variety of ruthenium(II)-arene complexes with
dppz based ligands and some of them demonstrated remarkable cytotoxic activity [3].
Following these studies here we present a series of Ru(II)-arene complexes with the general
formula [(η6-arene)Ru(dppz-R)Cl]PF6, where arene fragment was benzene, toluene or pcymene and R was -NO2, -Me or -COOMe with aim to study influence of both of half-sandwich
Ru(II)-arene fragments and the variation of dppz ligands on improvement of the therapeutic
potential of those complexes. All compounds were fully characterized by physico-chemical
methods. The anticancer activity of dppz ligands and respective Ru complexes was assessed
against MDA-MB-231, HCT116 and CT26 cancer cell lines and healthy MRC5 lung
fibroblasts. In vivo efficacy of lead Ru-dppz complex revealed significantly reduction of tumor
burden in mice with colorectal cancers without inducing liver and kidney toxicity. Thus, all the
results indicated that introducing appropriate dppz into ruthenium-arene scaffold was a
promising strategy for developing potent antitumor agents.

AB  - The use of truffles in food is based mainly on the addition of artificial flavors, aiming to achieve an intense aroma in the products. As truffle is a natural product with nutritional and functional properties, it is important to find an optimal method for truffle storage. As the microbiota contribute to truffle aroma, the bacterial and yeast compositions in the rhizosphere and fruiting body of the truffle and the impact of different freezing methods on the volatile profile of the truffle Tuber aestivum during 90 days of the storage were determined. Bacteria and yeasts isolates were identified using 16s rRNA and 18s rRNA. The effect of freezing truffles at -20°C and -80°C with and without previous dipping in liquid N2 on the volatile compounds was observed using GC/MS. The results demonstrated that the isolated bacteria belonged to the phylum Proteobacteria, Firmicutes and Actinobacteria, and the identified species mainly belonged to Firmicutes, genus Bacillus sp. Isolated yeasts were identified as Cryptococcus sp., Debaromyces hanseinii, Candida fermentati and Rhodotorula mucilaginosa. The GC/MS analysis revealed that frozen truffle samples were richer in the compounds 2-butanone, 2-methyl-butanal, methanethiol and 2-butanol after freezing or during storage. The content of DMS, acetaldehyde, 3-octanone, ethanol, and 2-methyl-1-propanol significantly decreased immediately after freezing. Overall, the gained results indicated that freezing of truffles as a preservation method had profound effects on the volatile compounds, while previous dipping in liquid N2 showed no significant impact on the volatile profile of truffle Tuber aestivum. © 2023 University of Belgrade - Faculty of Agriculture.

AB  - The mobility of chemical elements in the soil-orchid system has been poorly studied. The aim of this study is to evaluate the uptake and mobility of several trace (Li, Ba, Sr, Ag, Hg, and B) and macronutrients (Ca, Mg, and K) in the orchid Anacamptis morio (L.) R.M.Bateman, Pridgeon & M.W.Chase from soils in western Serbia. The sampling sites are characterized by three different bedrock types—cherts, limestones, and serpentines, which are the source of the significant chemical differences in the elemental status of the soil and plant tissues. The four-step Community Bureau of Reference sequential extraction procedure was used to determine the distribution of fractions and predict their potential phytoavailability. The orchid and soil samples were analyzed for total elemental content analysis using ICP-OES. The greatest potential for plant availability was determined for Ba and Sr, representing about 80% of the total soil content. More than 40% of Li in the soils was found to be potentially phytoavailable. Significant correlations were found between the total content of Li, B, and Sr in soils. Between 38 and 60% of Li content and more than 80% of Ba and Sr content were determined to be potentially phytoavailable by sequential analysis. The highest bioconcentration factor (> 1) was determined in the case of B and Sr for all orchid organs, while translocation factor for Li was highest in tubers and leaves. The studied elements were mainly stored in tubers and roots, indicating the exclusion strategy of A. morio as a metal tolerance mechanism. The data obtained showed significant differences in metal content in soils and plants originating from sites with different parent materials, suggesting that bedrock type and associated soil properties are important factors that determine chemical element mobility and uptake.

AB  - There are ten million people in the world who have Parkinson’s disease. The most potent
medicine for Parkinson’s disease is levodopa (L-DOPA). However, long-term consumption of L-DOPA
leads to the appearance of side effects, as a result of which the control and monitoring of its concentrations are of great importance. In this work, we have designed a new electrochemical sensor for
detecting L-DOPA using a carbon paste electrode (CPE) modified with Eu2O3@Cr2O3 composite
nanoparticles. Rare earth elements, including Eu, are increasingly used to design new electrode
nanocomposites with enhanced electrocatalytic properties. Europium has been considered a significant lanthanide element with greater redox reaction behavior. We conducted a hydrothermal
synthesis of Eu2O3@Cr2O3 and, for the first time, the acquired nanoparticles were used to modify
CPE. The proposed Eu2O3@Cr2O3/CPE electrode was investigated in terms of its electrocatalytic
properties and then used to develop an analytical method for detecting and quantifying L-DOPA.
The proposed sensor offers a wide linear range (1–100 µM), high sensitivity (1.38 µA µM−1
cm−2
) and
a low detection limit (0.72 µM). The practical application of the proposed sensor was investigated by
analyzing commercially available pharmaceutical tablets of L-DOPA. The corresponding results indicate
the excellent potential of the Eu2O3@Cr2O3/CPE sensor for application in real-time L-DOPA detection

detecting L-DOPA using a carbon paste electrode (CPE) modified with Eu2O3@Cr2O3 composite
nanoparticles. Rare earth elements, including Eu, are increasingly used to design new electrode
nanocomposites with enhanced electrocatalytic properties. Europium has been considered a significant lanthanide element with greater redox reaction behavior. We conducted a hydrothermal
synthesis of Eu2O3@Cr2O3 and, for the first time, the acquired nanoparticles were used to modify
CPE. The proposed Eu2O3@Cr2O3/CPE electrode was investigated in terms of its electrocatalytic
properties and then used to develop an analytical method for detecting and quantifying L-DOPA.
The proposed sensor offers a wide linear range (1–100 µM), high sensitivity (1.38 µA µM−1
cm−2
) and
a low detection limit (0.72 µM). The practical application of the proposed sensor was investigated by
analyzing commercially available pharmaceutical tablets of L-DOPA. The corresponding results indicate
the excellent potential of the Eu2O3@Cr2O3/CPE sensor for application in real-time L-DOPA detection",

AB  - In this investigation, samples of SrGd2O4 doped with different Yb3+ (2, 4, 6 at.%) ions and constant Ho3+ (1 at.%) and Bi3+ (2 at.%) concentrations were prepared. The sol-gel method with glycine as a fuel and citric acid as a chelator was chosen for sample preparation. All samples were heated in the furnace for 1.5 h at 500 °C and then thermally treated for 2.5 h at 1000 °C. The pure orthorhombic lattice of SrGd2O4, space group Pnma, was revealed by X-ray diffraction (XRD) (JCPDS Card No.:01-072-6387). Transmission electron microscopy (TEM) discovered agglomerated clusters of spherical particles measuring around 150 nm in size. Including Bi3+ ions into the structure influenced the morphology of the sample showing fine packing of pyramidal-shaped nanoparticles. The uniform distribution of constitutive elements in the samples was confirmed by energy dispersive spectroscopy (EDS). Up-conversion emission properties were evaluated from photoluminescent emission spectra and intensity dependence on excitation power after excitation at 976 nm. Dominant green (550 nm), red (671 nm), and infrared (758 nm) 5F4, 5S2 → 5I8, 5F5 → 5I8, 5F4, 5S2 → 5I7 transition emissions, respectively, are detected in all samples. The sample co-doped with Bi3+ showed the most intense photoluminescent emission.

AB  - The aim of this research was to investigate for the first-time photocatalytic degradation of methylene blue over SrGd2O4 powders co-doped with constant Er3+ (0.5 at.%) and different Yb3+ (1, 2.5 and 5 at.%) concentrations. Samples were successfully prepared via sol-gel assisted combustion method. They exhibit photoluminescence properties which are manifested as red emission at 661 nm (4F9/2 → 4I15/2) and two green emissions at 551 and 523 nm (4S3/2 → 4I15/2 and 2H11/2 → 4I15/2). X-ray Powder Diffraction pattern proved that all samples crystallize as a pure orthorhombic phase. Scanning electron microscopy was used for morphology characterization and it revealed the existence of porous agglomerated round-shaped particles. Energy dispersive X-ray spectroscopy showed the presence of dopant ions and even distribution of all constituting elements. To calculate the energy band gap, UV-VIS diffuse reflectance spectroscopy was performed and a value of 4.3 eV was obtained, as well as the four additional values from the bands at lower energies. Photocatalytic degradation of methylene blue was monitored using UV-VIS absorption spectroscopy. Obtained results were promising since after 4 h of exposure to the simulating Sun irradiation, more than 50% of the starting dye concentration was mineralized.

AB  - In this investigation, samples of strontium-gadolinium-oxide (SrGd2O4) doped with different Yb3+ (2, 4 and 6 at%) and constant Ho3+ (1 at%) contents and co-doped with Bi3+ (2 at%) were prepared using the glycine-assisted sol–gel method. The pure orthorhombic SrGd2O4 phase, space group Pnma, was revealed using X-ray diffraction in all samples. Transmission electron microscopy discovered agglomerated clusters of spherical particles measuring approximately 150 nm in size. The inclusion of Bi3+ ions into the structure influenced the morphology since the formation of larger grains was observed, with sizes reaching up to ∼1.7 μm. The uniform distribution of all constitutive elements was confirmed by energy-dispersive X-ray spectroscopy. In all samples, up-conversion emission spectra revealed two dominant green (540 and 550 nm), red (671 nm), and infrared (758 nm) emission lines, due to the 5F4,5S2→5I8, 5F5→5I8, and 5F4,5S2 → 5I7 transitions, respectively. The sample co-doped with Bi3+ showed the most intense photoluminescent emissions, shorter luminescence decay, and the highest quantum yield. Additionally, a significant decrease in the energy band gap value was detected using diffuse reflectance spectroscopy for this sample. Methylene blue was used as a test pollutant to investigate its photocatalytic efficiency under simulated sunlight irradiation. The results show that Bi3+ co-doping deteriorates the photocatalytic efficiency of the SrGd2O4:Yb3+/Ho3+ phase by reducing hydroxyl radical formation.

AB  - Varroa destructor is a parasitic mite responsible for the loss of honey bee (Apis mellifera) colonies. This study aimed to find a promising marker in honey for the bee colony infestation level using fluorescence spectroscopy and biochemical analyses. We examined whether the parameters of the honey samples’ fluorescence spectra and biochemical parameters, both related to proteins and phenolics, may be connected with the level of honey bee colonies’ infestation. The infestation level was highly positively correlated with the catalase activity in honey (r = 0.936). Additionally, the infestation level was positively correlated with the phenolic spectral component (r = 0.656), which was tentatively related to the phenolics in honey. No correlation was found between the diastase activity in honey and the colonies’ infestation level. The results indicate that the catalase activity in honey and the PFC1 spectral component may be reliable markers for the V. destructor infestation level of the colonies. The obtained data may be related to the honey yield obtained from the apiaries.

AB  - Microplastics is abundant in the environment, food and beverages and get ingested by humans. Its complex interplay with proteins lead to formation of corona. Tightly bound proteins represent hard corona, while weaker binding partners are found in soft corona. Separation of hard and soft corona of allergenic proteins of shrimps, eggs and cow’s milk, tropomyosin (TPM), ovalbumin (OVA) and beta-lactoglobulin (BLG) and identification of binding partners by proteomics was aim of our study.
Allergenic proteins were purified from egg white, shrimps and cow’s milk. Binding to polyethylene terephthalate microplastics (PET) (70-100 m) was probed at pH 7 for purified allergens and egg white proteins. After establishment of binding equilibrium, soft and hard corona were separated and analyzed by SDS PAGE, followed by identification of bound proteins by nanoLC-HRMS. Binding of all allergenic proteins was observed in both soft and hard corona. Soft corona contains exclusively intact, full length OVA, TPM and BLG. Hard corona is enriched for truncated OVA and oligomers of TPM. OVA fragments are partially or fully enfolded and have higher level of exposed hydrophobic patches resulting in higher affinity for PET microplastics. In comparison to OVA and TPM, hard corona of BLG is less abundant under similar conditions. BLG is compact globular protein with lower level of exposed hydrophobic patches in comparison to ovalbumin and tropomyosin. In hard corona, trace amounts of contaminating alfa-lactalbumin become enriched. In the presence of egg white protein extract OVA forms both SC and HC on microplastics, being the dominant protein of hard corona (with ovotransferrin). Lysozyme and ovomucin are present only in hard corona. Both proteins are known for their strong bioactivity and represent a small fraction of total egg white proteins.
Our results show that allergenic proteins form hard corona on PET microplastics. Among egg white proteins, minor proteins such as lysozyme and ovomucin become enriched. Denaturing effect of strong binding to microplastics may change functional characteristics of allergens and bioactive proteins of foods and should be further investigated in functional assays.

abstract = "Microplastics is abundant in the environment, food and beverages and get ingested by humans. Its complex interplay with proteins lead to formation of corona. Tightly bound proteins represent hard corona, while weaker binding partners are found in soft corona. Separation of hard and soft corona of allergenic proteins of shrimps, eggs and cow’s milk, tropomyosin (TPM), ovalbumin (OVA) and beta-lactoglobulin (BLG) and identification of binding partners by proteomics was aim of our study.
Allergenic proteins were purified from egg white, shrimps and cow’s milk. Binding to polyethylene terephthalate microplastics (PET) (70-100 m) was probed at pH 7 for purified allergens and egg white proteins. After establishment of binding equilibrium, soft and hard corona were separated and analyzed by SDS PAGE, followed by identification of bound proteins by nanoLC-HRMS. Binding of all allergenic proteins was observed in both soft and hard corona. Soft corona contains exclusively intact, full length OVA, TPM and BLG. Hard corona is enriched for truncated OVA and oligomers of TPM. OVA fragments are partially or fully enfolded and have higher level of exposed hydrophobic patches resulting in higher affinity for PET microplastics. In comparison to OVA and TPM, hard corona of BLG is less abundant under similar conditions. BLG is compact globular protein with lower level of exposed hydrophobic patches in comparison to ovalbumin and tropomyosin. In hard corona, trace amounts of contaminating alfa-lactalbumin become enriched. In the presence of egg white protein extract OVA forms both SC and HC on microplastics, being the dominant protein of hard corona (with ovotransferrin). Lysozyme and ovomucin are present only in hard corona. Both proteins are known for their strong bioactivity and represent a small fraction of total egg white proteins.
Our results show that allergenic proteins form hard corona on PET microplastics. Among egg white proteins, minor proteins such as lysozyme and ovomucin become enriched. Denaturing effect of strong binding to microplastics may change functional characteristics of allergens and bioactive proteins of foods and should be further investigated in functional assays.
