- Abstract
Beeswax is one of the most important products for the well-being of bee colonies. The wax glands of young worker bees produce beeswax, which serves as a building material for honeycomb construction. Beekeepers using hives with mobile frames mainly utilize local beeswax to make foundations. Any paraffin addition represents adulteration, resulting in a high degree of contamination. During the preparation of re-used beeswax, losses during the process may instigate producers to add cheaper, wax-like substances like paraffin and tallow. This article presents a systematic investigation of the quality of beeswax foundation from six major producers in Vojvodina, Serbia, by applying the classic analytical procedure for the determination of selected physicochemical parameters and instrumental gas chromatography coupled with mass spectrometry (GC–MS) and Fourier transform infrared attenuated total reflection (FTIR–ATR) spectroscopy techniques. FTIR–ATR detected possible paraffin and beef tallow in 72 foundation sheet samples. This technique was complemented with GC–MS. This analysis revealed that paraffin content ranged between 19.75 and 85.68%, while no tallow was detected over the two-year period. Two sheets from each manufacturer were placed into wired Langstroth–Ruth frames and placed in beehives. The construction, based on built cells, was monitored every 24 h. Evaluating newly inserted sheets proved that without quality nectar, there is no intensive building, regardless of adulteration. [ABSTRACT FROM AUTHOR] more...

Malta, a country renowned for its honey, has not been extensively mentioned in studies based on honey. In addition to many parameters, the collection period affects honey quality, precisely due to the different floral composition that exists during a certain season. Therefore, the significance of this study refers to the provision of data on honey from Malta collected during the autumn, spring, and summer seasons. Melissopalynological analysis, determination of physicochemical parameters, and the use of analytical chromatographic methods enabled detailed analysis of this honey. Principal component analysis (PCA) provided the differentiation of Maltese honey depending on the harvest season. Lotus pollen, followed by Eucalyptus, predominated in all honey samples. Characteristic compounds for summer honey were pinocembrin, galangin, kaempferol, chrysin, p-hydroxybenzoic acid, vanillic acid and maltotriose, while quercetin 3-O-galactoside, ferulic acid, ellagic acid, protocatechuic acid, luteolin 7-O-glucoside and melibiose were specific for autumn honey. A higher amount of p-coumaric acid, genistein, catechin, as well as the content of many sugars were found in spring samples. To the best of our knowledge, this is the first scientific work dealing with a detailed chemical analysis of Maltese honey more...

Beech -- Environmental aspects ,Soil erosion -- Research ,Forestry research ,Forest soils -- Research ,Earth sciences - Abstract
Forests in Europe are currently not endangered by soil erosion. However, this can change with climate change or with intensified forest management practices. Using a newly established network of plots in beech forests across Europe, the aims of this study were to (i) distinguish soil properties and erodibility indices in relation to bedrock, (ii) determine geochemical properties and organic carbon ([C.sub.org]) influencing erodibility, and (iii) assess the effect of soil depth on erodibility indices. Seventy-six soil samples from 20 beech forests were collected in 11 countries to quantify soil properties influencing erodibility indices: clay ratio, modified clay ratio, sodium adsorption ratio, and oxides ratio. The results indicate that the dominant soil properties, determined by bedrock, that correlate with forest soil erodibility indices are [C.sub.org], pH, electrical conductivity, calcium and sodium ions concentrations, total water-soluble cations, and the percentage of sand. According to the tested indices, soil susceptibility to erosion follows the order granite > andesite > sandstone > quartzite > limestone. Deeper soil horizons on granite are more susceptible to erosion than surface horizons are, but this is not the case for soils on limestones. In conclusion, forest management should consider the predisposition of different soil types to erosion. Key words: bedrock, environmental change, texture, organic matter, geochemistry, CLIMO COST Action. Les forets europeennes ne sont pas presentement menacees par l'erosion des sols. Cela pourrait cependant changer a cause des changements climatiques ou de l'intensification des pratiques d'amenagement forestier. En utilisant un reseau de parcelles echantillons etablies recemment dans des hetraies a travers l'Europe, cette etude visait les objectifs suivants : (i) distinguer les proprietes du sol et les indices d'erodabilite en relation avec la nature du substrat rocheux; (ii) determiner les proprietes geochimiques qui influencent l'erodabilite et (iii) evaluer l'effet de la profondeur du sol sur l'alternance des proprietes geochimiques et des indices d'erodabilite. Soixante- seize echantillons de sol provenant de 20 hetraies ont ete preleves dans 11 pays pour quantifier la texture et les proprietes physico-chimiques du sol. Quatre indices d'erodabilite ont ete utilises : le ratio d'argile, le ratio d'argile modifie, le ratio d'adsorption du sodium (Na) et le ratio d'oxydes. Les resultats indiquent que les proprietes du sol sont fortement influencees par le substrat rocheux et cette influence est plus grande que celle des autres facteurs abiotiques. Les plus importantes proprietes du sol qui sont correlees avec les indices d'erodabilite des sols forestiers sont : le carbone organique ([C.sub.org]), le pH, la conductivite electrique, les concentrations en ions calcium et Na, les cations hydrosolubles totaux et le pourcentage de sable. Selon les indices testes, l'erodabilite du sol suit la sequence suivante : granite > andesite > gres > quartzite > calcaire. Les indices montrent que cette sequence est accentuee en fonction de la profondeur dans le profil de sol. Les horizons les plus profonds sur les substrats rocheux granitiques sont plus erodables que les horizons de surface alors que ce n'est pas le cas des sols situes sur du calcaire. En conclusion, l'amenagement forestier devrait tenir compte des predispositions des differents types de sols a l'erosion.

- Abstract
Polyphenolic compounds are of great interest in today’s science. Naturally, they occur in plants and other sources in many different forms. Their wide range of biological activity has attracted the attention of the scientific community. One of the sources of phenolic compounds is stinging nettle (Urtica dioica L.), a common plant in almost all parts of the world. A long tradition of utilization and an interesting chemical profile make this plant a fascinating and extensive object of study. The chemical profile also allows this plant to be used as a food and a pigment source in the food, pharmaceutical, and cosmetic industries. Previously conducted studies found phenolic acids and polyphenolic compounds in root, stalk, and stinging nettle leaves. Different extraction techniques were usually used to isolate them from the leaves. Obtained extracts were used to investigate biological activity further or formulate different functional food products. This study aimed to collect all available knowledge about this plant, its chemical composition, and biological activity and to summarize this knowledge with particular attention to polyphenolic compounds and the activity and mechanisms of their actions. more...

- Abstract
Ethnopharmacological relevance: Acute coronary syndrome (ACS) represents a group of diseases that are the result of reduced blood flow to the heart. There are natural products, based on mushrooms, used traditionally in the treatment of cardiovascular diseases. Aim of the study: Assessment of the potential protective effect of L. betulinus mushroom against therapy-induced DNA damage in lymphocytes of patients with ACS in relation to the phytochemical properties of the mushroom. Materials and methods: The study included 30 ACS patients and 30 healthy controls. The genotoxic potential of acetone and ethanol extract of L. betulinus was evaluated using the comet assay. The contents of minerals were determined by inductively coupled plasma optical emission spectrometry. Determination of sugars and organic acids was performed using a DIONEX ICS 3000 DP liquid chromatography system. Analysis of fatty acids was performed at Focus GC coupled with PolarisQ mass spectrometer. The total phenolic and flavonoid contents in the mushroom extracts were measured using spectrophotometric methods. The qualitative and quantitative content of polyphenolic compounds was investigated by the UHPLC-DADMS/MS method. Results: The comet assay showed that both mushroom extracts did not increase the level of DNA damage in the lymphocytes of healthy individuals, while they significantly decreased the %DNA damage and genetic damage index (p < 0.0005) in the therapy-induced lymphocytes of patients. The mushroom was very rich in phytochemical composition. The results showed that the most abundant components in the mushroom were phosphorus, potassium, sodium, sulfur, and calcium among minerals and glucose, fructose, galactose, sorbitol, and turanose among carbohydrates. Among organic acids were present in higher concentrations malic, citric, and maleic acids, while among fatty acids, the most abundant were trans-linoleic, cis-oleic, palmitic, docosahexaenoic and eicosadienoic acids. The results showed more...

Fragile X syndrome (FXS) is caused by the full mutation in the FMR1 gene on the Xq27.3 chromosome region. It is the most common monogenic cause of autism spectrum disorder (ASD) and inherited intellectual disability (ID). Besides ASD and ID and other symptoms, individuals with FXS may exhibit sleep problems and impairment of circadian rhythm (CR). The Drosophila melanogaster models of FXS, such as dFMR1
B55 , represent excellent models for research in the FXS field. During this study, sleep patterns and CR in dFMR1B55 mutants were analyzed, using a new platform based on continuous high-resolution videography integrated with a highly-customized version of an open-source software. This methodology provides more sensitive results, which could be crucial for all further research in this model of fruit flies. The study revealed that dFMR1B55 male mutants sleep more and can be considered weak rhythmic flies rather than totally arrhythmic and present a good alternative animal model of genetic disorder, which includes impairment of CR and sleep behavior. The combination of affordable videography and software used in the current study is a significant improvement over previous methods and will enable broader adaptation of such high-resolution behavior monitoring methods.

ACUTE kidney failure ,GUT microbiome ,ANIMAL mortality ,ENERGY metabolism ,HEART diseases - Abstract
Sepsis-induced multiple organ dysfunction arises from the highly complex pathophysiology encompassing the interplay of inflammation, oxidative stress, endothelial dysfunction, mitochondrial damage, cellular energy failure, and dysbiosis. Over the past decades, numerous studies have been dedicated to elucidating the underlying molecular mechanisms of sepsis in order to develop effective treatments. Current research underscores liver and cardiac dysfunction, along with acute lung and kidney injuries, as predominant causes of mortality in sepsis patients. This understanding of sepsis-induced organ failure unveils potential therapeutic targets for sepsis treatment. Various novel therapeutics, including melatonin, metformin, palmitoylethanolamide (PEA), certain herbal extracts, and gut microbiota modulators, have demonstrated efficacy in different sepsis models. In recent years, the research focus has shifted from anti-inflammatory and antioxidative agents to exploring the modulation of energy metabolism and gut microbiota in sepsis. These approaches have shown a significant impact in preventing multiple organ damage and mortality in various animal sepsis models but require further clinical investigation. The accumulation of this knowledge enriches our understanding of sepsis and is anticipated to facilitate the development of effective therapeutic strategies in the future.

L-ascorbic acid represents one of the most potent antioxidant, photoprotective, anti-aging, and anti-pigmentation cosmeceutical agents, with a good safety profile. However, the main challenge is the formulation of stable topical formulation products, which would optimize the penetrability of L-ascorbic acid through the skin. The aim of our research was to evaluate the performance of ascorbyl palmitate on the skin, incorporated in creams and emulgels (2%) as carriers, as well as to determine the impact of its incorporation into liposomes on the penetration profile of this ingredient. Tape stripping was used to study the penetration of ascorbyl palmitate into the stratum corneum. In addition, the sensory and textural properties of the formulations were determined. The liposomal formulations exhibited a better penetration profile (p < 0.05) of the active substance compared to the non-liposomal counterpart, leading to a 1.3-fold and 1.2 fold-increase in the total amount of penetrated ascorbyl palmitate in the stratum corneum for the emulgel and cream, respectively. Encapsulation of ascorbyl palmitate into liposomes led to an increase in the adhesiveness and density of the prepared cream and emulgel samples. The best spreadability and absorption during application were detected in liposomal samples. The obtained results confirmed that liposomal encapsulation of ascorbyl palmitate improved dermal penetration for both the cream and emulgel formulations. [ABSTRACT FROM AUTHOR] more...

The aim of this study was to determine fatty acid and soluble sugar profiles of the grape seed flour originated from non-fermented dried pomace of international and autochthonous grape varieties in order to estimate their potential nutritional value. The grape seed flours were obtained from the grapes harvested in technological maturity. It has been shown that grape seed flours contained significant quantities of unsaturated fatty acids (UFAs), especially linoleic fatty acids, whose content ranged from 61.15 - 83.47 %. Oleic acid mostly contributed to the content of monounsaturated fatty acids, while the stearic acid was the most abundant saturated fatty acid (SFA). Among polyunsaturated fatty acids, mainly ω-6 FAs, were the most represented. The tested grape seed flours had the high UFA/SFA ratio (3.63- 11.09), low atherogenicity (0.04-0.13) and thrombogenicity (0.16-0.47) indices. Fifteen different sugars were found in analysed samples with the total concentration ranging from 40588 to 91319 mg/kg seed with fructose and glucose as the most abundant. Principal component analysis based on the content of FAs and soluble sugars revealed unique composition of the seed flour of Prokupac variety. These findings indicate that the tested grape seed flours is a good source of nutritionally valuable FAs and sugars that can play an important role in the formulation of a new functional food products.

The mushroom industry should implement green extraction technologies; however, there is not enough information on the differences between these techniques expressed as the chemical composition of the resulting extract. In this study, selected types of green extraction techniques (GETs) were used on Chaga (Inonotus obliquus) (Fr.) Pilát from Serbia (IS) and Mongolia (IM) to examine the differences that would enable the composition-based technology choices in the mushroom supplement industry. Subcritical water extraction (SWE), microwave-assisted (MW) extraction, and ultrasonic-assisted extraction (VAE) were used to prepare the extracts. SWE was performed at two different temperatures (120 and 200 °C), while 96% ethanol, 50% ethanol, and water were used for MW and VAE. The yield, the content of total phenols, total proteins, and carbohydrates, qualitative and quantitative analysis of phenolic compounds, carbohydrates, including α- and β- and total glucans, and fatty acids, were determined in the obtained extracts. SWE resulted in a significantly higher yield, total polysaccharide, and glucan content than any other technique. Glucose was the most dominant monosaccharide in the SWE samples, especially those extracted at 200 °C. The MW 50% EtOH extracts showed the highest yield of total phenols. Among the tested phenolic compounds, chlorogenic acid was the most dominant. SWE can be recommended as the most efficient method for extracting commercially important compounds, especially glucans and phenols. [ABSTRACT FROM AUTHOR] more...

- Abstract
A diversity of factors, led by lithology, weathering, and erosion processes, plays a significant role in the formation and future of badland terrains. Then on previous observations it can be concluded that surface flow processes are the first trigger of erosion and that intense soil erosion combined with rapid and deep weathering are tightly connected to high erosion rates. Since climate change presents a global issue that gains increasing attention and due to the complexity of the interactions and processes that are a part of general badlands origin and evolution, a weathering experiment on badland sediments from China was conducted. Explaining temporal changes, the impact of different precipitation types and its durations of exposure on sediments during weathering processes, as well as its impact on leachate ions behaviour are the aims behind this experiment. Red clayey siltstone and mudstone badland sediments selected for the laboratory experiment were organized in four sets that included three different samples, making a total of 12 treated samples. Based on field climate data, in laboratory conditions samples were exposed to rain, acid rain, snow, and acid snow through fifteen daily cycles. Leachate was collected after each cycle and its volume, pH, electrical conductivity (EC), and ion concentrations were measured and analysed from the leachate. Changes occurring on the surface of the sample were observed through photographs taken at the end of each cycle. Based on obtained results it can be said that the main differences occur when comparing rain and snow treatments generally. Temporal, cyclic changes were, to a certain extent, noticed through sediment decay. More importantly, durations of sediment exposure to precipitation proved to be crucial for weathering processes of tested siltstones and mudstones, having exclusion and ionic forces - ion exchange chromatography as dominant chemical processes. more...

- Abstract
The aim of the study was the comparative analysis of degradation of wheat straw lignin by white-rot fungi and its implications on the efficiency of enzymatic hydrolysis of holocellulose. Peroxidases were found to be predominantly responsible for lignin degradation, even though high laccase activities were detected, especially in the initial stages of fungal culturing. The studied fungal species showed various ability to degrade lignin in wheat straw, which further affected the release of reducing sugars during enzymatic saccharification. The highest rate of lignin, hemicelluloses and cellulose degradation was noticed in the sample pretreated with Irpex lacteus. Among all the tested species, only Ganoderma resinaceum was found as a suitable lignin degrader, with 2-fold higher hydrolysis yield (51.1 ± 4.7%) than in the control. A key mechanism that enhances convertibility of carbohydrates is the selective lignin removal from biomass. Operating time, holocellulose loss and unpredictable fungal response to culturing conditions are the main challenges in fungal pretreatment of lignocellulosic feedstock. more...

- Abstract
In this study we compared materials from less investigated badland sites in Turkey and China. Critical composition in badland material is the presence and ratio of the clay and silt size particles, clay mineralogy and presence of mobile ions, especially anions. In analyzed materials the presence of smectite governed the formation of surface crust. Surface cracks enabled ion leaching and became preferential paths from sediment movement. Critical composition in badland material is the presence and ratio of the clay and silt size particles and poor sorting. Sulphate and carbonate ions proved to be crucial for surface processes on these materials. Summarizing results it can be concluded that erodibility of badland lithologies is a combination of clay type, silt content and ion concentration. more...

- Abstract
Stinging nettle (SN) is an extraordinary plant from the Urticaceae botanical family. It is well-known and widely used in food and folk medicine to treat different disorders and diseases. This article aimed to study the chemical composition of SN leaves extracts, i.e., polyphenolic compounds and vitamins B and C, because many studies ascribed high biological potency to these compounds and their significance in the human diet. Besides the chemical profile, the thermal properties of the extracts were studied. The results confirmed presence of many polyphenolic compounds and vitamins B and C. It also showed that the chemical profile closely correlated with the applied extraction technique. The thermal analysis showed that analyzed samples were thermally stable up to about 160 °C. Thermal degradation of samples UAE, MAE, and MAC took place in four steps, and sample SE in three steps. Altogether, results confirmed the presence of health-beneficial compounds in stinging nettle leaves and indicated the possible application of its extract in pharmaceutical and food industries as both a medicinal and food additive. more...

- Abstract
The dual controlled release of emulgels makes them efficient drug delivery systems of increasing interest. The framework of this study was to incorporate selected L-ascorbic acid derivatives into emulgels. From the formulated emulgels, the release profiles of actives were evaluated considering their different polarities and concentrations, and consequently their effectiveness on the skin via a long-term in vivo study that lasted for 30 days was determined. Skin effects were assessed by measuring the electrical capacitance of the stratum corneum (EC), trans-epidermal water loss (TEWL), melanin index (MI) and skin pH. In addition, the sensory and textural properties of emulgel formulations were compared with each other. The changes in the rate of the release of the L-ascorbic acid derivatives were monitored using the Franz diffusion cells. The obtained data were statistically significant, and indicated an increase in the degree of hydration of the skin and skin whitening potential, while no significant changes in TEWL and pH values were detected. The consistency, firmness and stickiness of the emulgels were estimated by volunteers applying the established sensory evaluation protocol. In addition, it was revealed that the difference in hydrophilic/lipophilic properties of L-ascorbic acid derivatives influenced their release profiles without changing their textural characteristics. Therefore, this study highlighted emulgels as L-ascorbic acid suitable carrier systems and one of the promising candidates as novel drug delivery systems. more...

- Abstract
The aim of this study was to find the chemical parameters for the differentiation of plum cultivars grown along the fjord areas of Western Norway and Eastern Norway, having specific agroclimatic conditions. Chemical analysis of the fruits confirmed the contents of 13 quantified elements, 22 sugar compounds, 11 organic acids, 19 phenolic compounds, and antioxidant activity in 68 plum cultivars. Dominated contents were noted for nitrogen (with the maximum mean value of 3.11%), potassium (8055.80 mg/kg), and phosphorous (7878.88 mg/kg). Averagely, the highest level of sugars was determined for glucose (244.46 g/kg), fructose (197.92 g/kg), sucrose (208.25 g/kg), and sorbitol (98.02 g/kg), organic acids for malic acid (24.06 g/kg), and for polyphenol compounds were 5-O-caffeoylquinic acid (66.31 mg/kg), and rutin (58.06 mg/kg). Applied principal component analysis has been useful for distinguishing the plum cultivars from three areas in Norway where copper, iron, potassium, magnesium, manganese, and sodium; sucrose, ribose, maltose, and raffinose; p-hydroxybenzoic acid, rutin, ferulic acid, kaempferol 7-O-glucoside, p-coumaric acid, and 5-Ocaffeoylquinic acid were the most influential. In regard to human health and future breeding work that will have the aim to produce functional food with high health-related compounds, the plum cultivar ‘Mallard’ should be underlined due to the high level of elements, ‘Valor’ due to high sugar content, ‘Helgøyplomme’ due to content of organic acids, and ‘Diamond’ due to the content of phenolic compounds. more...

- Abstract
Usled modernog načina života ljudi provode oko 90 % vremena u zatvorenim prostorijama, kao što su kuće/stanovi, kancelarije, automobili itd. Prašina je sve prisutna u svim pomenutim sredinama i nalazi se kao čestice suspendovane u vazduhu ili istaložena na površinama. Čestice prašine se mogu lako udahnuti i mogu da oštete respiratorni sistem i pluća. Pored toga, čestice prašine akumuliraju hemikalije iz zatvorenih prostorija i predstavljaju važan put izlaganja ljudi tim jedinjenjima. U kućnoj prašini se mogu naći ftalati, policiklični aromatični ugljovodonici i ostala poluisparljiva jedinjenja. Ftalati se često koriste kao plastifikator u proizvodnji polivinil hlorida (PVC-a) i predmeta opšte upotrebe kao što su građevinski materijal, dečije igračke i nameštaj, ali i u proizvodnji podnih obloga, veštačke kože, lepkova, tepiha, maziva, cevi, žica, sredstava za čišćenje kuće, proizvoda za negu tela (fiksatori mirisa, proizvodi za negu kože, pene i šamponi) i ambalaže za namirnice. Primena ftalata zavisi od njihove molekulske mase. Ftalati male molekulske mase, kao što su di-metil-ftalat (DMP), di-etil-ftalat (DEP), di-propil-ftalat (DPP), di-izobutil-ftalat (DiBP), di-n-butil ftalat (DBP), di-n-pentil-ftalat (DNPP) i benzil- butil-ftalat (BBP), se koriste u rastvaračima, lepkovima, voskovima, mastilu, lekovima, kozmetici i insekticidima.Visokomolekulski ftalati, kao di-2-etilheksil-ftalat (DEHP), di- ciklo-heksil-ftalat (DCHP) i di-izo-nonil-ftalat (DiNP), su plastifikatori u PVC proizvodima i predmetima od opšte upotrebe. Estri ftalata su povezani sa velikim brojem zdravstvenih problema kod ljudi. Pre svega, ftalati deluju kao endokrini disruptori i doprinose stvaranju varijacija u reprodukcionom sistemu kao što su opadanje broja spermatozoida, oštećenje DNK u spermatozoidima, prevremeni razvoj dojki i promena u reproduktivnim hormonima. Ftalati utiču na pojavu astme, alergija i poremećaja funkcije nervnog sistema. Pored toga, DEHP je okarakterisan kao 2b kancerogena more...

- Abstract
The topography and morpho-anatomical characteristics of floral nectaries and the chemical analysis of nectar have been studied in seven pear cultivars with different susceptibility to Erwinia amylovora. The susceptible cultivar Williams, the moderately resistant cultivars Bella di guigno, Poire de Cure and the low susceptible cultivar Alexander Lucas originated from Pyrus communis, while highly resistant cultivars Chojuro and Nijisseiki from P. pyraster and Kieffer as interspecies hybrid P. communis × P. pyraster were included in this experiment and studied for the first time. Large differences in size and structure of the nectaries were observed in these seven pear cultivars. The epidermal cells were with cuticle being more or less striated in Alexander Lucas, Kieffer and Williams. Resistant cultivars had a narrow, elongated cell shape of epidermal cells while those susceptible had an isodiametric. Stomata were mesomorphic in all cultivars except in Poire de Cure and Williams, being slightly xeromorphic since they were situated in deep hollows. Guard cells of the modified stomata were much larger in resistant cultivars. Hypanthium cells were larger in resistant compared to susceptible cultivars. The most abundant sugars were glucose, fructose, sorbitol and sucrose in nectar of all studied pear cultivars. The resistant cultivars (Chojuro, Kieffer and Nijisseiki) had a ~2-fold higher level of sorbitol and galactose, ~2.2-fold higher isomaltose, ~2.7-fold turanose, ~3.35-fold maltose, ~4.4-fold melibiose and ~12.7-fold higher melesitose compared to susceptible cultivars. The sum of quantified phenolic acids varied from 0.049 (Williams) up to 4.074 µg CAE/mL (Kieffer), while flavonoid glycosides levels ranged from 1.224 (Williams) up to 11.686 µg RE/mL (Nijisseiki). In the nectar of the resistant cultivars, rutin, apigetrin, together with patuletin and luteolin glycosides were detected but not in susceptible cultivars, which could be considered as the markers of resist more...

Degradation and detoxification efficiency of high concentrations of commercially available reactive textile dye Reactive Black 5 solution (40, 80, 200, 500, 1000 mg L-1), were studied. Advanced oxidation processes in water falling film based dielectric barrier discharge as a non-thermal plasma reactor were used. For the first time, this reactor was used for the treatment of high concentrations of organic pollutants such as reactive textile dye Reactive Black 5 in water. Solution of the dye is treated by plasma as thin water solution film that is constantly regenerated. Basically, the reactor works as a continuous flow reactor and the electrical discharge itself takes place at the gas-liquid interphase. The dye solution was recirculated through the reactor with an applied energy density of 0-374 kJ L-1. Decolorization efficiency (%) was monitored by UV-VIS spectrophotometric technique. Samples were taken after every recirculation (~ 22 kJ L-1) and decolorization percent was measured after 5 min and 24 h of plasma treatment. The efficiency of degradation (i.e. mineralization) and possible degradation products were also tracked by determination of the chemical oxygen demand (COD) and by ion chromatography (IC). Initial toxicity and toxicity of solutions after the treatment were studied with Artemia salina test organisms. Efficiency of decolorization decreased with the increase of the dye concentration. Complete decolorization, high mineralization and non-toxicity of the solution ( more...

In this study, we tested the methanolic and acetonic extracts of the edible speciesMeripilus giganteusfor their medicinal properties. Here, we present the chemical composition, as well as the antimicrobial, antioxidant, antidiabetic, neuroprotective, and cytotoxic activities, of the aforementioned extracts. The chemical composition of the extracts was analyzed with high-performance liquid chromatography coupled with diode-array detection and tandem mass spectrometry. The studied extracts contained 13 minerals, 23 polyphenols, 11 organic acids, and 22 carbohydrates. Antimicrobial activity was tested by applying the microdilution assay, and the results ranged from 0.002 to 20 mg/mL. Antioxidant activity was studied with the DPPH assay (half-maximal inhibitory concentration = 673.42 and 712.31 μg/mL for the methanolic and acetonic extracts, respectively) and the reducing power assay (range, 0.042-0.099 μg/mL). Total phenolic content was determined as 4.86 mg gallic acid equivalents (GAE)/g for the methanolic extract and 5.06 mg GAE/g for the acetonic extract. The antidiabetic effect of the extracts was explored with the α-amylase and α-glucosidase assays, and the results ranged from 30.66% to 38.67% and from 11.06% to 17.08%, respectively. The neuroprotective properties ofM. giganteusextracts were studied using the acetylcholinesterase inhibition assay, with results ranging from 4.54% to 9.31%. Cytotoxic activity was tested by applying the microtetrazolium assay, with results ranging from 196.24 to 322.83 μg/mL. Although some assays proved relatively limited activities of theM. giganteusextracts studied, they can still be considered as natural sources of bioactive compounds without side effects. more...

- Abstract
У индустријској зони града Ковина налазe се фабрике које се баве производњом алкохола и сточног квасца, хране за кућне љубимце, сечењем и завршном обрадом челика, производњом шприцева и амбалаже за вакцине и лекове, као и највећа на Балкану фарма печурака. Поред тога, на 11 km од Ковина је рудник који угаљ вади са дна језера које је повезано са Дунавом, и представља јединствену подводну експлоатацију угља на свету. Упркос наведеним бројним делатностима које могу имати утицаја на квалитет површинских вода, нема лабораторије која се бави њиховим мониторингом. Стога је циљ овог рада прелиминарна карактеризација степена оптерећења површинских вода укупно присутним и специфичним, најзаступљенијим угљоводоничним загађујућим супстанцама. Узорци коришћени у раду узети су током новембра 2022. године, са пет репрезентативних локација на подручју Ковина (слика 1). Након одређивања основних параметара (табела 1), воде су анализиране применом стандардне методе ASTM D1252-06 [1], како би се утврдиле вредности хемијске потрошње кисеоника (ХПК). У циљу специфицирања најзаступљенијих угљоводоничних загађујућих супстанци, примењена је екстракција узорака вода помоћу трихлорметана. Добијени екстракти су након сушења и концентровања хроматографски пречишћени и анализирани на гасном хроматографу Agilent 7890A GC куплованом са квадруполним масеним детектором Agilent 5975C. Четири од пет анализираних узорака показују вредности ХПК карактеристичне за класу III површинских вода (табела 1; [2]). Најзаступљeнија специфична угљоводонична једињења у свим узорцима су n-алкани (слика 1). Нижи n-алкани са мање од 20 угљеникових атома су присутни само у траговима, што указује да ове воде углавном нису изложене загађењу сировом нафтом, дизелом или керозином. У три узорка (Дунавац, Шљункара и Црна Бара), CPI вредности за цео опсег n-алкана (С16- С34), као и за и више (С25-С34) и ниже (С15-С20, са изузетком Шљункаре) n-алканске хомологе су ниже или блиске 1, што уз n-алканске максимуме у опсегу С24-С26 указује на допринос органске супстанце акватичних макрофита, бактерија, васкуларних биљака и маховина рода Sphagnum [3]. Присуство нижих n-алкана (С15-С20) карактерише алге и бактерије, док се доминација непарних нижих хомолога у узорку Шљункара може повезати за цијанобактеријама. У узорицима Канал и Поњавица CPI вредности за цео опсег n-алкана (С16-С34), као и за више хомологе (С25-С34) веће су од 1, што уз n-алкански максимум у узорку Канал на С27 указује на допринос виших сувоземних биљака. Међутим поред наведених природних извора идентификованих n-алкана, треба истаћи да веома сличне n-алканске расподеле имају моторна уља, теже фракције уља за ложење и течни производи пиролизе лигнита. Од посебног значаја је и резултат да је у екстракту узорка воде са локације Поњавица доминантно једињење елементарни сумпор (слика 1), што се може повезати са великом количином муља у којем преовлађују аноксични услови, услед чега су фаворизовани редукциони хемијски/биохемијски процеси. Резултати прелиминарног истраживања показују да је неопходно наставити континуално и знатно детаљније истраживање предметних вода, како би се предупредило њихово даље загађење и негативан утицај на живи свет у њима, као и на подземне воде и земљиште у непосредној околини. Постерска презентација представљена је на 9. симпозијуму Хемија и заштита животне средине ENVIROCHEM2023 са међународним учешћем у Кладову, Србија у периоду од 04. до 07. јуна 2023. године. more...

In this study, we have investigated the chemical composition and bioactive properties of methanolic and acetonic extracts of the edible mushroomLaetiporus sulphureus. Chemical characterization of the extracts was done with HPLC-DAD-MS/MS method. The results revealed that the most abundant components in both extracts were potassium among minerals, chlorogenic acid among polyphenols, malic acid among organic acids, and glucose among carbohydrates. Antimicrobial activity of the extracts was studied by applying the microdilution assay, and the results were in the range of 0.310–20mg/mL. Antioxidant activity was tested with DPPH and the reducing power assay. IC50 values in the DPPH assay were 769.440 and 730.840μg/mL for methanolic and acetonic extracts, respectively. The results of the reducing power assay ranged from 0.010 to 0.048. The total phenolic content was also determined; in the methanolic extract, it was 5.510mg GA/gand in the acetonic, 4.140mg GA/g. The α-amylase and α-glucosidase inhibition assays were used to determine the antidiabetic activity of extracts, and the results were in the ranges of 30.180–37.730% and 14.310–21.340%, respectively. The neuroprotective activity of extracts was tested using the acetylcholinesterase inhibition assay, and the results ranged from 3.640 to 8.840%. The cytotoxic activity was studied using the microtetrazolium assay and the IC50 values ranged between 211.590 and 362.770μg/mL. This study indicates thatL. sulphureuscan be considered an edible mushroom with a high nutritional and functional value. more...
