AB  - Maple syrup, a popular natural sweetener has a high content of sucrose, whose consumption is linked to different health issues such as obesity and diabetes. Hence, within this paper, the conversion of sucrose to prebiotics (fructo-oligosaccharides, FOS) was proposed as a promising approach to obtaining a healthier, value-added product. Enzymatic conversion was optimized with respect to key experimental factors, and thereafter derived immobilized preparation of fructosyltransferase (FTase) from Pectinex® Ultra SP-L (FTase-epoxy Purolite, 255 IU/g support) was successfully utilized to produce novel functional product in ten consecutive reaction cycles. The product, obtained under optimal conditions (60 ◦C, 7.65 IU/mL, 12 h), resulted in 56.0% FOS, 16.7% sucrose, and 27.3% monosaccharides of total carbohydrates, leading to a 1.6-fold reduction in caloric content. The obtained products` prebiotic potential toward the probiotic strain Lactobacillus plantarum 299v was demonstrated. The changes in physico-chemical and sensorial characteristics were esteemed as negligible.

AB  - Providing structural information on drug-like compounds is a significant step in efforts to develop innovative drugs with balanced solubility, cell permeability and target binding. In this paper, a new cyclohexane-5-spirohydantoin tethered with a 4‑tert-butylbenzoyl group was synthesized and its crystal structure was determined using the single crystal X-ray diffraction. The Hirshfeld surface analysis was used to gain a preliminary insight into the proportion and nature of the intermolecular interactions in the crystal structure, while their quantitative description is further presented in terms of a systematic analysis of dimeric motifs representing different recognition modes. A combination of N–H∙∙∙O and C(sp3)–H∙∙∙O hydrogen bonds, C(sp3)–H∙∙∙π, lone-pair∙∙∙π and π∙∙∙π stacking interactions links the molecules into a bilayer having two carbonyl O atoms exposed to the exterior. Further stacking of the bilayers occurs through C(sp3)–H∙∙∙O hydrogen bonds involving these O atoms as acceptors, C(sp3)–H∙∙∙π and π∙∙∙π stacking interactions between the phenyl groups. The molecular electrostatic potential surface map reveals that the carbonyl O atoms of the hydantoin ring and the phenyl ring are electrophilic centers, while the N1–H1 group is a nucleophilic center. The calculated HOMO and LUMO energies were used to semiquantitatively estimate the global reactivity descriptors suggesting the soft nature of the molecule.

AB  - Pesticides used in coffee cultivation may remain behind and pose a risk to humans even after various processing stages of coffee beans (washing, drying, roasting, and grinding). In addition to pesticides applied to battle pests and diseases, mepiquat formation occurs during roasting. A comprehensive LC-MS/MS and GC-MS/MS multi-residue screening approach to determine pesticides in coffee was used in this study. Residues were extracted using the QuEChERS method and analyzed using multiple reaction monitoring (MRM) mass spectrometry after chromatographic separations. Good linearity (r2˃0.9919), recovery (80.2–118%), and RSD (≤19%) were obtained for the procedure including sample preparation and both instrumental techniques. Nine residues were identified as commonly present in coffee samples collected from supermarkets in Serbia. The human intake risk of pesticides was categorized and prioritized using the matrix ranking scheme. Also, health risk assessment was conducted by calculating acute and chronic hazard indices. Multi-residues were present in 79.2% of samples, whereas mepiquat chloride (88.9%) and permethrin (81.9%) were the most detected residues. Risk ranking classified mepiquat chloride, permethrin, and methiocarb sulfone in a high-risk group. On the other hand, the human health risk assessment indicated no risks in the short- and long-term and no cumulative chronic risk.

AB  - This study focuses on the development of bioactive materials using environmentally friendly techniques, renewable, biocompatible, and biodegradable polysaccharide, as well as natural bioactive compounds (NBCs) found in plant extracts. First, cornstarch aerogels with a porosity of 86 % and a specific surface area of 225 m2/g were produced via supercritical CO2- assisted drying. Further, thymol, citronellol, carvacrol, and eugenol were incorporated into the aerogels by supercritical CO2- assisted impregnation, which allowed variation in loadings of NBCs (12.8–17.6 %). Interaction between cornstarch aerogels and NBCs determined impregnation rate, pore wall thickness (in the range 18–95 nm), liquid absorption capacity (from 265 to 569 %), dehydration mass loss, and release in phosphate-buffered saline. Controlled release of NBCs was maintained over a 3-day period. Moreover, impregnated aerogels showed a significant antioxidant effect with the highest value for DPPH radical inhibition of 25.5 % determined for the aerogels impregnated with eugenol. Notable antimicrobial activity against tested Gram-negative bacteria, Gram-positive bacteria, and fungi was also observed, being the highest for thymol-loaded aerogel with the diameter of the inhibition zones of up to 37.5 mm. This work shows a promising green approach for the production of bioactive two-component starch-based materials for potential applications in skin infection treatment.

AB  - This study present estimation of the thermodynamic parameters and the influence of ionic activity coefficient on the thermodynamic equilibrium constant of adsorption of phosphates on fly ash. The adsorption was conducted over a wide range of initial phosphate concentrations at different pH values pH = (3; 7; 10). The adsorption results were treated using the Langmuir, Freundlich and Sips adsorption isotherms, which provide information about the maximum adsorption capacity. The Langmuir and Sips isotherms were a satisfactory fit to the adsorption data, especially at pH = 3, with an acceptable regression coefficient over the entire concentration range, Langmuir (r2 = 0.9737) and Sips (r2 = 0.9969). The estimated maximum phosphate sorption capacity of fly ash was 6.21 ± 0.68 (mmol·g−1) according to Langmuir and 4.19 ± 0.16 (mmol·g−1) according to the Sips model, at pH = 3.0. However, there is no data in the published literature for estimating the thermodynamic parameters of the phosphate adsorption process using thermodynamic models for activity coefficients. Novel approach of this paper was determination of the thermodynamic equilibrium constant and Gibbs free energy, using the Pitzer ion-interaction model to predict the nature of adsorption. The Pitzer-ion interaction model was used for the mixed ionic systems, taking into consideration the effect of other present ions besides phosphates in the equilibrium solution resulting from fly ash desorption. The procedure for comprehensive estimation of the ion activity coefficient at maximum adsorption capacity and the dimensionless thermodynamic equilibrium constant using Langmuir's and Sips's constants was presented. The calculated value of the phosphate activity coefficient in the equilibrium solution was γH = 0.7003 ± 0.0027 and the converted molar activity coefficient was γH = 0.6903 ± 0.0027. The estimated values of Gibbs free energy were: ΔGL = −6.788 ± 0.521 kJ·mol−1 based on Langmuir equilibrium constant and ΔGa = −7.707 ± 0.527 kJ·mol−1 based on activity and thermodynamic equilibrium constant. According to Sips model, the adsorption process is even more spontaneous, with the Gibbs free energy calculated using the phosphate activity coefficient and the thermodynamic equilibrium constant, ΔGa = −9.707 ± 0.617 kJ·mol−1. Consideration of the ionic activity coefficient is particularly important for large, charged adsorbates at higher concentrations, as the absolute difference in free energy for adsorption is app. 12 %. The scientific contribution is reflected in obtaining the necessary and more accurate information for the improvement of adsorption processes and possibly for the upgrading of fly ash in overall wastewater treatment technology.

Asymmetric bidentate coordination of the carboxylato ligands and skew trapezoidal structures are assumed for
the synthesized complexes. In vitro anticancer activity of the synthesized diphenyltin(IV) complexes was evaluated against three human: MCF-7 (breast adenocarcinoma), A375 (melanoma), HCT116 (colorectal carcinoma),
and three mouse tumor cell lines: 4T1 (breast carcinoma), B16 (melanoma), CT26 (colon carcinoma) using MTT
and CV assays. The IC50 values fall in the range from 0.1 to 3.7 μM. Flow cytometric analysis and fluorescent
microscopy suggest that complex 1 induces caspase-dependent apoptosis followed with strong blockade of cell
division in HCT116 cells. Since complex 1 showed ROS/RNS scavenging potential mentioned cytotoxicity was
not connected with oxidative stress.

AB  - The syntheses of Ag-based nanoparticles (NPs) with the assistance of plant extracts have been shown to be environmentally benign and cost-effective alternatives to conventional chemical syntheses. This study discusses the application of Paliurus spina-christi, Juglans regia, Humulus lupulus, and Sambucus nigra leaf extracts for in situ synthesis of Ag-based NPs on cotton fabric modified with citric acid. The presence of NPs with an average size ranging from 57 to 99 nm on the fiber surface was confirmed by FESEM. XPS analysis indicated that metallic (Ag0) and/or ionic silver (Ag2O and AgO) appeared on the surface of the modified cotton. The chemical composition, size, shape, and amounts of synthesized NPs were strongly dependent on the applied plant extract. All fabricated nanocomposites exhibited excellent antifungal activity against yeast Candida albicans. Antibacterial activity was significantly stronger against Gram-positive bacteria Staphylococcus aureus than Gram-negative bacteria Escherichia coli. In addition, 99% of silver was retained on the samples after 24 h of contact with physiological saline solution, implying a high stability of nanoparticles. Cytotoxic activity towards HaCaT and MRC5 cells was only observed for the sample synthetized in the presence of H. lupulus extract. Excellent antimicrobial activity and non-cytotoxicity make the developed composites efficient candidates for medicinal applications.

AB  - This study explores the impact of sodium periodate oxidation time (30min, 60min, or 120min) and alginate coating on the capillarity of jute fabrics. Raw jute fabric exhibits a rapid increase in capillary rise height (h) over time, reaching 72mm at 1200s. Fabrics oxidized for 30, 60, and 120min show significantly lower h values of 19, 18, and 28mm at 1200s, respectively, which can be ascribed to the oxidation process itself. Precisely, oxidation-induced conversion of hydroxyl
groups of cellulose (the main constituent of jute fiber) to aldehyde groups contributed to the fabric reduced affinity for water, hence negatively affecting its capillarity. Approximately 47% and 55% lower h values of fabrics oxidized for 30 and 60min compared to that oxidized for 120min can be explained by their lower weight loss after oxidation as well as less pronounced liberation of elementary fibers. Oxidized fabrics characterized by low capillarity can be used for the manufacturing of packaging materials, outdoor gear, and protective covers for crops. To expand jute fabric applications in biocarpet engineering, that is, to obtain polysaccharide-based supports, raw and oxidized jute fabrics were treated with a 1% sodium alginate solution. At 1200s, oxidized fabrics coated with alginate exhibited 4.3–5.8 times higher h values compared to solely oxidized counterparts. The diffusion coefficients of oxidized fabrics coated with alginate increase up to 35% with prolonged oxidation, emphasizing the oxidation impact on alginate binding.

AB  - This study presents an innovative approach for the reuse and recycling of waste material, brewer’s spent grain (BSG) for
creating a novel green biocatalyst. The same BSG was utilized in several consecutive steps: initially, it served as a substrate
for the cultivation and production of laccase by a novel isolated fungal strain, Coriolopsis trogii 2SMKN, then, it was reused
as a carrier for laccase immobilization, aiding in the process of azo dye decolorization and fnally, reused as recycled BSG
for the second successful laccase immobilization for six guaiacol oxidation, contributing to a zero-waste strategy. The novel
fungal strain produced laccase with a maximum activity of 171.4 U/g after 6 days of solid-state fermentation using BSG
as a substrate. The obtained laccase exhibited excellent performance in the decolorization of azo dyes, both as a free and
immobilized, at high temperatures, without addition of harmful mediators, achieving maximum decolorization efciencies
of 99.0%, 71.2%, and 61.0% for Orange G (OG), Congo Red, and Eriochrome Black T (EBT), respectively. The immobilized
laccase on BSG was successfully reused across fve cycles of azo dye decolorization process. Notably, new green biocatalyst
outperformed commercial laccase from Aspergillus spp. in the decolorization of OG and EBT. GC-MS and LC-MS revealed
azo-dye degradation products and decomposition pathway. This analysis was complemented by antimicrobial and phytotoxicity tests, which confrmed the non-toxic nature of the degradation products, indicating the potential for safe environmental
disposal.

abstract = "This study presents an innovative approach for the reuse and recycling of waste material, brewer’s spent grain (BSG) for
creating a novel green biocatalyst. The same BSG was utilized in several consecutive steps: initially, it served as a substrate
for the cultivation and production of laccase by a novel isolated fungal strain, Coriolopsis trogii 2SMKN, then, it was reused
as a carrier for laccase immobilization, aiding in the process of azo dye decolorization and fnally, reused as recycled BSG
for the second successful laccase immobilization for six guaiacol oxidation, contributing to a zero-waste strategy. The novel
fungal strain produced laccase with a maximum activity of 171.4 U/g after 6 days of solid-state fermentation using BSG
as a substrate. The obtained laccase exhibited excellent performance in the decolorization of azo dyes, both as a free and
immobilized, at high temperatures, without addition of harmful mediators, achieving maximum decolorization efciencies
of 99.0%, 71.2%, and 61.0% for Orange G (OG), Congo Red, and Eriochrome Black T (EBT), respectively. The immobilized
laccase on BSG was successfully reused across fve cycles of azo dye decolorization process. Notably, new green biocatalyst
outperformed commercial laccase from Aspergillus spp. in the decolorization of OG and EBT. GC-MS and LC-MS revealed
azo-dye degradation products and decomposition pathway. This analysis was complemented by antimicrobial and phytotoxicity tests, which confrmed the non-toxic nature of the degradation products, indicating the potential for safe environmental
disposal.",

AB  - Polymer composites based on unsaturated polyester resin (UPR) and reinforced with particles based on unmodified/modifiedplant provenance biosilica particles were synthesized and characterized. An unsaturated polyester resin was obtained fromwaste poly (ethylene terephthalate (PET). Biosilaca particles are made from rice husk biomass. The surface of the producedsilica particles was modified using three different silanes: 3-trimethoxysilylpropyl methacrylate (MEMO), trimethoxyvinylsilane (TMEVS), and 3-aminopropyltrimethoxysilane (APTMS). The microhardness test method was used to investigatethe mechanical properties of synthesized composite material with variations in dwell times and applied loads. Optimization ofcomposite microhardness value prediction in function of synthesized parameters (type of modification of silica particles) andmeasurement parameters (applied loads and dwell times) was done using the method of response surface methodology (RSM)regression analysis. The maximal microhardness values (0.459 GPa) were obtained of type modification of silica particles withvinyl with 80% confidence for 120 experimental variables. This method can be used to choose the optimal dwell time and loadfor comparison of measurements between different composite materials and to enable the choice of the material in terms ofoptimization of the quality of reinforcement and quality of interphase determined by surface modification.

Nakon 48-časovne hidrolize u dobijenim hidrolizatima je određivan sadržaj heksoza i pentoza. Sadržaj lignina smanjen je za 40% tokom tretmana plazmom u trajanju od 30 minuta u etanolu. U slučaju vode razgrađeno je 20% lignina pri istoj dužini tretmana. Međutim, produžavanjem dužine tretmana na 60 minuta u vodi postignuta je značajna delignifikacija, smanjenjem sadržaja lignina za 50% u odnosu na netretiranu biomasu. Dodatno produžavanje tretmana plazmom na 90 minuta nije dovelo do povećanja stepena delignifikacije. Prinosi šećera ostvareni nakon hidrolize su u skladu sa delignifikacijom, pri čemu je najveći prinos postignut nakon plazma tretmana u etanolu tokom 30 minuta, odnosno u vodi tokom 60 minuta. Primenom kombinovanog plazma tretmana moguće je razgraditi lignin i olakšati prodor enzima do ugljeno-hidratne komponente lignoceluloze pri atmosferskim uslovima, bez upotrebe jakih kiselina, baza ili organskih rastvarača. Upotrebom navedenih zelenih rastvarača smanjuje se potreba za dodatnim koracima prečišćavanja tretirane biomase, a i naknadne faze enzimske hidrolize i fermentacije su značajno jednostavnije.

AB  - Due to the depletion of fossil fuel sources and the issues posed by climate change, there is an increasing demand for renewable and sustainable fuel alternatives. Biofuels are a viable replacement for fossil fuels since they are made from renewable biomass. Degradation and valorization of renewable biomass start in the biorefinery with the main goal of producing biofuels and biochemicals in a more sustainable way. Lignocellulosic biomass (LB) presents one of the most abundant feedstocks for low-carbon fuel production. Enzymes belonging to cellulase, xylanase, pectinase, laccase, amylase, and lipase are utilized for biomass degradation and for the biofuels production. The emphasis of this chapter will be on the smart degrading enzymes designed to produce the two low-carbon biofuels, bioethanol and biodiesel, which are mostly used in the industrial sector. The technological development of commercial enzymes involved in biofuel and chemical production is also discussed.

AB  - Engineered wood products along with advanced processing and fabrication are pushing the limits of modern wood construction. Innovative concepts and applications facilitate the development of a new generation of structural systems. However, capacities of such systems are often governed by capabilities of the connections. This paper presents the experimental results with numerical and analytical models of angle brackets for prediction of load bearing capacity, stiffness, and ductility.
Three types of metal brackets in beam-column connections have been investigated and their performance has been studied in various loading arrangements. Detailed finite-element models of each connection have been developed to gain insights into their behavior. An analytical approach is also adopted to represent the connections. Comparison with test data suggests that
the models can reproduce results with good accuracy. The findings confirm feasibility of implementing ductile connections in practical mass timber structures.

AB  - Kopriva (Urtica dioica) je samonikla biljka bogata flavonoidima, karotenoidima, fitosterolima,
terpenima. Ima izuzetan farmaceutski potencijal zbog svojih antiinflamatornih, antioksidativnih i
diuretskih svojstava. Koristi se u ishrani, kao caj ili u formi suvih ili tecnih ekstrakta. U cilju
pobiljšanja karakteristika, bioraspoloživosti i stabilnosti ekstrakata, koriste se ekstrakcije ekološki
prihvatljivim rastvaracima, zeleni fizicki tretmani i fermentacija probiotickim bakterijama. Zeleni
rastvaraci kao što su voda, etanol i biokompatibilni eutekticke tecnosti su pogodni za dobijanje
ekstrakata u skladu sa principima održivog razvoja. Inovativni fizicki tretmani kao netermalni
tretman plazmom mogu obezbediti bolju ekstrakciju i mikrobiološku stabilnost posebno vodenih
ekstrakata. Takode, fermentacije bakterijama, kao što je Ligilactobacillus salivarius, mogu da
metabolišu jedinjenja prisutna u ekstraktima i biotransformišu glikozide, tanine i lignane u biološki
aktivnije oblike.
U radu smo ispitivali rast i antioksidativnu aktivnost vodenih ekstrakata cveta koprive dobijenih uz
tretman netermalnom plazmom i potom fermentaciju sa L. salivarius. Ispitali smo rast L. salivarius
u medijumima sa razlicitim udelom vodenog ekstrata cveta koprive i Man Rogosa Šarp (MRS) bujona
koji je koristi kao standardni mikrobiološki medijum za kultivaciju bakterija mlecne kiseline.
Antioksidativna aktivnost dobijenih ekstrakata je ispitana DPPH metodom, pre i nakon fermentacije.
L. salivarius je pokazao najbolji rast (11 log CFU/ml) u ekstraktima obogacenim sa 25% MRS. Potom
je je ispitivan rast L. salivarius u plazma tretiranom vodenom ekstraktu koprive sa 25% MRS. Nakon
tretmana netermalnom plazmom od 3 min i naknadne fermentacije ovih ekstrakata, postignut je rast
od 9 log CFU/ml i porast antioksidativne aktivnosti od 27% DPPH metodom. Uocen je pozitivan
kombinovani efekat netermalne plazme i fermentacije na povecanje antioksidativne aktivnosti,
posebno pri kracim tretmanima netermalnom plazmom. Rezultati rada ukazuju na mogucnost
primene zelenih tretmana i fermentacije za dobijanje proizvoda ekstrakta cveta koprive obogacenih
sa L. salivarius. Plazma tretman može uticati i na mikrobiološki sastav vodenih ekstrakata, kao
važnog aspekta za primenu u prehrambenoj i farmaceutskoj industriji.

abstract = "Kopriva (Urtica dioica) je samonikla biljka bogata flavonoidima, karotenoidima, fitosterolima,
terpenima. Ima izuzetan farmaceutski potencijal zbog svojih antiinflamatornih, antioksidativnih i
diuretskih svojstava. Koristi se u ishrani, kao caj ili u formi suvih ili tecnih ekstrakta. U cilju
pobiljšanja karakteristika, bioraspoloživosti i stabilnosti ekstrakata, koriste se ekstrakcije ekološki
prihvatljivim rastvaracima, zeleni fizicki tretmani i fermentacija probiotickim bakterijama. Zeleni
rastvaraci kao što su voda, etanol i biokompatibilni eutekticke tecnosti su pogodni za dobijanje
ekstrakata u skladu sa principima održivog razvoja. Inovativni fizicki tretmani kao netermalni
tretman plazmom mogu obezbediti bolju ekstrakciju i mikrobiološku stabilnost posebno vodenih
ekstrakata. Takode, fermentacije bakterijama, kao što je Ligilactobacillus salivarius, mogu da
metabolišu jedinjenja prisutna u ekstraktima i biotransformišu glikozide, tanine i lignane u biološki
aktivnije oblike.
U radu smo ispitivali rast i antioksidativnu aktivnost vodenih ekstrakata cveta koprive dobijenih uz
tretman netermalnom plazmom i potom fermentaciju sa L. salivarius. Ispitali smo rast L. salivarius
u medijumima sa razlicitim udelom vodenog ekstrata cveta koprive i Man Rogosa Šarp (MRS) bujona
koji je koristi kao standardni mikrobiološki medijum za kultivaciju bakterija mlecne kiseline.
Antioksidativna aktivnost dobijenih ekstrakata je ispitana DPPH metodom, pre i nakon fermentacije.
L. salivarius je pokazao najbolji rast (11 log CFU/ml) u ekstraktima obogacenim sa 25% MRS. Potom
je je ispitivan rast L. salivarius u plazma tretiranom vodenom ekstraktu koprive sa 25% MRS. Nakon
tretmana netermalnom plazmom od 3 min i naknadne fermentacije ovih ekstrakata, postignut je rast
od 9 log CFU/ml i porast antioksidativne aktivnosti od 27% DPPH metodom. Uocen je pozitivan
kombinovani efekat netermalne plazme i fermentacije na povecanje antioksidativne aktivnosti,
posebno pri kracim tretmanima netermalnom plazmom. Rezultati rada ukazuju na mogucnost
primene zelenih tretmana i fermentacije za dobijanje proizvoda ekstrakta cveta koprive obogacenih
sa L. salivarius. Plazma tretman može uticati i na mikrobiološki sastav vodenih ekstrakata, kao
važnog aspekta za primenu u prehrambenoj i farmaceutskoj industriji.",

AB  - In this work, we present a two-phase electro-magneto-fluid dynamics (EMFD) model that merges electromagnetics and fluid dynamics. The model is suitable for use in computational fluid dynamics (CFD) software and was incorporated into OpenFOAM® after deriving appropriate equations that bypassed certain limitations of the software. Currently, there is a lack of even single-phase EMFD models that can be incorporated in CFD software, while simpler models from electrohydrodynamics (EHD) and magnetohydrodynamics (MHD) are being implemented, though they have certain approximations that can limit their applicability. We conclude that the derived EMFD model is applicable and show its quality by implementing it and analyzing the results. We use cases with a droplet and the electrospinning process for verification. The drop deformations obtained were closer to analytical predictions than in the literature for two EHD models, but some oscillations were observed. We compared one simulation to the prediction of an analytical equation from MHD, and good agreement was shown. Finally, we simulate the electrospinning process, and the results were very close to the analytical predictions. We conclude that the implementation can be used for both EHD and MHD cases.

AB  - The function of immune complexes in rheumatoid arthritis (RA) is related to their composition and size. Using dynamic light scattering (DLS), we investigated the link between the RA circulating immune complex (CIC) particles’ size and the CIC immunoglobulin level. In this study, 30 RA patients and 30 healthy individuals were included. IgA, IgG, and IgM were found in all analyzed CICs, but more IgA and IgG were found in RA than in control CICs. In both control and RA CICs, DLS detected 50 particles that differed in size and clustered around two size groups: with a 7.5–164 nm radius and with a 342–1718 nm radius. An increased level of IgA in RA CICs, compared to control ones, was associated with more than 50% of CIC particles. In RA, compared to the control, a higher number of CICs with 28.2 nm, 531 nm, 712 nm, and 1718 nm particles and a lower number of CICs with 78.8 nm particles were detected. This particle distribution pattern did not reflect the changes in the CIC immunoglobulin level. Thus, RA elevated CIC IgA was linked with all these particles (except the 1718 nm particle), the IgM increase was linked with 43.8 nm and 712 nm particles, and the IgG increase was linked with the 712 nm particle only. This study provides the very first data on the association between CIC particles’ size, CIC immunoglobulin level, and RA. It opens the possibility that the size of CICs determined by DLS can be used as a criterion in RA diagnosis or monitoring after a large-scale study confirmation.

AB  - The electrokinetic properties of materials give useful insight into the behavior of surfaces in contact with liquids and other compounds and their quantification is a powerful tool to predict their behavior during further processing and application, especially in textile materials. In this work, we perform a comparative analysis of influence of the two most common selective oxidative protocols for viscose (regenerated cellulose) fabrics on subsequent functionalization with chitosan, and cellulose fabrics’ electrokinetic properties, zeta potential in a pH range of approx. 3–10, and isoelectric point (IEP). For oxidation before deposition of chitosan, sodium periodate and 2,2,6,6-tetramethylpiperidine-1-oxy radical (TEMPO) were used. The content of functional groups in oxidized cellulose fabric (carboxyl and carbonyl groups) was determined by titration methods, while amino functional groups’ availability in samples with chitosan was determined using the CI acid orange 7 dye absorption method. This study reveals that the periodate oxidation (PO) of cellulose is more effective for binding chitosan onto material, which gave rise to higher availability of amino groups onto cellulose/chitosan material, which also influenced the shift in zeta potential curve towards positive values at a pH below 5. Analysis of a relationship between zeta potential increase at pH 4.4 and amino groups’ amount measured using absorption of CI acid orange 7 dye at pH 4.4 revealed dependency that can be fitted linearly or exponentially, with the latter providing the better fit (R2 = 0.75).

AB  - Population growth, urbanization, industry, floods, and agriculture globally degrade groundwater in river plains, necessitating action for its quality assessment and management. Hence, a comprehensive methodology, including hydrogeochemical facies (Piper, Gibbs), irrigation indices (SAR, Wilcox), entropy-weighted water quality index (EWQI), positive matrix factorization (PMF), and Monte Carlo simulation of source-specific health risks was used in this study to analyze groundwater in the Morava river plain (Serbia). The results revealed a prevalent Ca–Mg–HCO3 groundwater type, influenced by water–rock interactions. Although groundwater was found suitable for irrigation, only 66.7 % of the samples were considered drinkable. Agricultural activities, natural processes, and municipal wastewater were identified as primary pollution sources. The incremental lifetime cancer risk (ILCR) and hazard index (HI) threshold exceedance for adults and children ranged from 8.5 % to 39 % of the samples, with arsenic identified as the most risk-contributing contaminant. These findings provide valuable insights for researchers studying groundwater vulnerability in river plains.

AB  - This study proposes synthesis and evaluation of gelatin-/alginate-based hydrogel scaffolds reinforced with titanium dioxide (TiO2) nanoparticles which, through their combination with allantoin, quercetin, and caffeic acid, provide multi-target therapy directed on all phases of the wound healing process. These scaffolds provide the simultaneous release of bioactive agents and concurrently support cell/tissue repair through the replicated structure of a native extracellular matrix. The hydrogel scaffolds were synthesized via a crosslinking reaction using EDC as a crosslinker for gelatin. Synthesized hydrogel scaffolds and the effect of TiO2 on their properties were characterized by structural, mechanical, morphological, and swelling properties, and the porosity, wettability, adhesion to skin tissue, and simultaneous release features. The biocompatibility of the scaffolds was tested in vitro on fibroblasts (MRC5 cells) and in vivo (Caenorhabditis elegans) in a survival probe. The scaffolds revealed porous interconnected morphology, porosity of 88.33 to 96.76%, elastic modulus of 1.53 to 4.29 MPa, full hydrophilicity, favorable skin adhesivity, and biocompatibility. The simultaneous release was investigated in vitro indicating dependence on the scaffold’s composition and type of bioactive agents. The novel scaffolds designed as multi-target therapy have significant promise for improved wound healing in a beneficial and non-invasive manner.

AB  - INTRODUCTION: Inflammation  process  in  human  body  can  lead  to  many serious inflammation-related  diseases. Hence, there are urge to find better solution for the treatment of the inflammation processes. Solution can be found in application  ofpoly(methacrylicacid)  hydrogels  which  have  potential  for  targeted  delivery  and  controlled  release  of drugs. These pH-sensitive hydrogelscan swell at the pH values between 5 and 8,and release drug in the process. So,taking into account that pH value at the inflammation site is around 6, these hydrogels are materials of choice. It  is  very  important thatthe system  for  controlled  releasebe  prepared  through mild  and  non-toxic  conditions  in order to preserve bioactivity of the drug andkeep good impact on environment. Enzymes are good candidates for eco-friendly preparation of hydrogels, because these greensubstancescan initiate polymerisation of various monomers. 
EXPERIMENTAL (or Materials and Methods):In this study, hydrogels based on poly(methacrylic acid) were prepared through  eco-friendly  method  by  using enzyme/hydrogen  peroxide(HP)/ascorbic  acid(AA)as  initiator.  Two  groupsof the samples were prepared: in the first group peroxidase isolated from potato peel waste (with activity of 0.8 IU) was used in the initiation system, whereas in the second group peroxidase isolated from soya bean coats (with activity of 0.8  IU) was  employed  in  the  initiation  system.  The  amounts  of HPand AAin  both  series  were  40  μL  and  10  mg, respectively.Anti-inflammatory drugs,dexamethasone(5 mg/mL)and diclofenac(4.5 mg/mL)were encapsulated in the first and the second group of the PMAA samples, respectively. Anti-inflammatory  effect of the PMAA hydrogels  with encapsulated drugs were tested on the Bovine Chondrocytes cells.
RESULTS  AND  DISCUSSION:Results  showed  that  the  level  of  pro-inflammatory  mediators  NO  and  IL-8  decreased. The PCR analysis showed that the proinflammatory TNα, IL-6 genesexpression level decreased, the matrix catabolism MMP1and MMP3 genesexpression level decreased and the fibrotic COL2 and ACAN genes expression level increased.
CONCLUSIONS:The studyshowed that the PMAA hydrogels have anti-inflammatory effect and have potential for treatment of the inflammation processes.
