AB  - The digestion stability of allergen pairs, tropomyosin, TM (fish and seafood allergen), and myosin light chain, MLC (chicken meat allergen) is compared among vertebrates and invertebrates in raw and cooked food matrix under standardized simulated in vitro gastrointestinal (GI) digestion. SDS-PAGE followed by multiple TM and MLC-specific antibodies in semidry WB revealed pepsin resistance of invertebrate TMs (abalone, oyster, shrimp) under diet-relevant conditions (raw, cooked). Vertebrate TMs (chicken, pork, beef) were less stable to digestion except that the raw chicken TM was observed pepsin resistant (not diet-relevant). Vertebrate (chicken) MLC was thermally stable. A new 28 kDa protein bound to anti-MLC antibody in cooked chicken and pork; could be the aggregates of MLC. Raw shrimp MLC showed pepsin resistance among invertebrates. A good correlation was observed between combined resistance of TM and MLC to GI digestion following the diet-relevant thermal treatment and reported protein allergenicity among vertebrates and invertebrates.

AB  - Triclosan (TCS) is a polychlorinated phenoxy phenol (PCPPs) used as a disinfectant and a broad-spectrum antibacterial and antifungal agent in personal hygiene products. TCS easily forms diphenyl ethers and dioxins, which are persistent organic pollutants.This work used a double approach for the TSC sensing: a) screen-printed (SPE) electrochemical platform for on-site application, modified with lanthanum iron oxide and graphitic carbon nitride composite (LaFeO3/Fe2O3@g-C3N4/SPE); and b) carbon paste electrode (CPE), modified with the same material and used in laboratory conditions. Linear range from 0.1 μM to 10 μM, the limit of detection (LOD) of 29 nM and the limit of quantification (LOQ) of 91 nM were obtained for CP electrode in BRBS pH 8. SPE showed the best analytical parameters in BRBS at pH 3, with a linear range from 0.3 μM to 7 μM, LOD of 0.09 μM and LOQ of 0.28 μM. Furthermore, the influence of potential interferents was investigated and proven to be negligible. Determination of TSC was performed to estimate the environmental impact of this compound as well as the practical usefulness of the proposed sensor in the real sample analysis, confirmed with a HPLC analysis.

AB  - Stable, water-soluble titanium complexed with mandelic acid was used as a precursor for titanium phosphorus double oxide obtained in hydrothermal conditions in the presence of phosphoric acid. Surprisingly, hydrolysis of organic complexes provided a microstructured sphere with narrow size distribution, low aggregation and a small fraction of morphological irregularities. Obtained microspheres had a complex structure comprised of flakes, whose size could be manipulated with temperature conditions. Samples were found to be electrochemically active against sulcotrione, a well-recognized herbicide. Electrochemical sensors based on the synthesized microspheres were successfully adapted for natural water reservoir analysis and exhibited low levels of detection of 0.61 µM, limit of quantification of 1.86 µM, wide dynamic linear range from 2 to 200 µM, good selectivity, excellent reproducibility and in-time stability.

AB  - Bisphenol A (BPA) is an organic pollutant that is widely spread in waterbody with effluents as a result of its extensive use in the plastics industry. It posses to the class of compounds that are endocrine disruptors and has a great negative impact on living organisms. Therefore, the progress in development of green technology for BPA removal from the aquatic media is crucial for environmental protection. This paper presents BPA removal by electrochemical oxidation on SnO2-MWCNT (tin dioxide-multi walled carbon nanotube) nanocomposite anode. The nanocomposite was structural and morphological characterized by X-ray powder diffraction and transmission electron microscopy. Electrochemical properties of the SnO2-MWCNT anode were investigated using cyclic voltammetry, linear sweep voltammetry and electrical impedance spectroscopy. The electrochemical behavior of anodes toward BPA in sodium sulfate solutions has shown that BPA is oxidized by indirectly mechanism via hydroxyl radicals (verified by quenching tests). Electrolysis of BPA has been done in galvanostatic regime at current densities 2.5, 5.0, 10.0, 15.0 and 20.0 mA cm−2 in 0.1 M sodium sulfate supported electrolyte pH 4.0. Complete degradation of BPA was accomplished after 5 h of electrolysis at a current density of 20 mA cm−2. The proposed electrochemical technology using a low-cost SnO2-MWCNT electrode is promising for wastewater BPA removal.

AB  - Considering the health-benefits of berry fruits consumption and increased market demands for food authenticity
as one of the most important quality assurances, phenolic profiling by high-performance thin layer chroma-
tography and ultra-high-performance liquid chromatography hyphenated with mass spectrometry was combined
with multivariate analysis for phytochemical characterization and intercultivar discrimination of cultivated
berry seeds. The phenolic profiles of 45 berry seeds from nine genuine Serbian cultivated fruit species (straw-
berry, raspberry, blackberry, black currant, blueberry, gooseberry, cape gooseberry, chokeberry, and goji berry)
revealed a good differentiation according to botanical origin. In order to determine biomarkers responsible for
the classification, a total of 103 phenolic compounds were identified, including 53 phenolic acids and their
derivatives, 26 flavonoids and 24 glycosides. Biomarkers derived from the phenolic profile of berry seeds proved
to be a powerful tool in the authentication of botanical origin, and may be useful in detection of frauds in berry-
based seed-containing product.

AB  - Gamma irradiation provides an alternative pathway to conventional gold nanoparticle synthesis because it is simple, fast, and economical. Here, we employed gamma irradiation at low doses (1–20 kGy) to obtain gold nanoparticles (Au NPs) anchored onto graphene oxide (GO) sheets. GO was selected as a suitable platform for the nucleation and growth of Au NPs because of its large surface area and good dispersibility in water due to the presence of polar oxygen-containing functional groups in its structure. Gamma irradiation at all the applied doses led to the reduction of chloroauric acid and the formation of evenly distributed Au NPs at the GO surface, simultaneously causing the reduction of GO and partial restoration of the graphene structure. As-prepared Au NPs have predominately spheric shapes and the smallest nanoparticles were reported for the dose of 1 kGy. The increase in the irradiation dose caused either the growth of larger particles (5 and 10 kGy) or the broad distribution of particles’ sizes (20 kGy). All samples showed a temperature increase upon exposure to 800 nm laser and photothermal efficiency was the highest for the sample prepared at 20 kGy.

AB  - MiR-21 and miR-375 have been reported as dysregulated in prostate cancer (PCa) in
multiple previous studies. Still, variable or even opposing data for the expression of these microRNAs
in PCa were found, and their potential biomarker properties remain elusive. In an attempt to clarify
their significance as PCa biomarkers, as well as to compare different types of specimens as a source
of relevant microRNAs, we used plasma and matching plasma-derived exosomes from patients with
PCa and patients with benign prostatic hyperplasia (BPH). Plasma and exosomes were obtained
from 34 patients with PCa and 34 patients with BPH, and their levels of expression of miR-21 and
miR-375 were determined by RT-qPCR. We found no significant difference in the level of expression
of these microRNAs in plasma and exosomes between patients with PCa and BPH. The level of
exosomal miR-21 was elevated in PCa patients with high serum PSA values, as well as in patients
with aggressive PCa, while for plasma samples, the results remained insignificant. For miR-375, we
did not find an association with the values of standard prognostic parameters of PCa, nor with cancer
aggressiveness. Therefore, our results support the potential prognostic role of exosomal miR-21
expression levels in PCa.

AB  - To minimize the impact of artificial food colouring (e.g., in drinks) on health, chemical dyes are increasingly replaced by natural 
ones. C-phycocyanin (C-PC), hexameric light-harvesting phycobiliprotein from cyanobacteria Artrhorspira platensis, has been 
proposed as an alternative. The intensive blue colour of C-PC arises from phycocyanobilin (PCB), the covalently attached 
tetrapyrrole chromophores. The presence of PCB chromophores gives C-PC a broad range of bioactive effects (antioxidant, 
anticancer, and immunomodulatory ones), substantially increasing their potential for applications in the food industry. However, 
C-PC issensitive to temperature, and its colour significantly diminishes by thermal treatment, limiting its use in the food industry. 
Hence, improving C-PC stability is the major challenge for successful application in food and beverage colouring. It is well 
known that binding small, high-affinity ligands significantly improve protein stability. Therefore, selecting food-derived ligands 
(such as vitamins, polyphenols, sugars, etc.) with the ability to bind C-PC firmly could be a promising strategy to increase the
C-PC stability and preserve its colour, which should increase its application potential in the food industry.
The main aim of this study is to characterize the binding of selected food-derived ligands (including quercetin, coenzyme Q10, 
gallic acid, vanillic acid, vanillin, resveratrol, glucose, fructose, sucrose, vitamin K, menthol, and dihydrolipoic acid) to C-PC 
by standard spectroscopic methods (UV/VIS absorption spectroscopy, spectrofluorimetry, and CD spectroscopy). Quercetin has
the strongest binding affinity to C-PC (Ka~3.7x105 M-1
), and its effects on C-PC structure and stability have been further 
investigated. CD spectroscopy revealed that quercetin induces stabilization of the protein secondary structure under simulated 
physiological conditions, while the conformation of the PCB chromophore is altered upon quercetin binding. Furthermore, 
quercetin binding increases the thermal stability of C-PC. 
Overall, our study revealed the ability of high-affinity, food-derived ligands to increase the stability of C-PC, which may enhance 
its application potential in the food industry.

AB  - : Post-translational modifications (PTMs) are covalent changes occurring on amino acid side
chains of proteins and yet are neglected structural and functional aspects of protein architecture. The
objective was to detect differences in PTM profiles that take place after roasting using open PTM
search. We conducted a bottom-up proteomic study to investigate the impact of peanut roasting on
readily soluble allergens and their PTM profiles. Proteomic PTM profiling of certain modifications
was confirmed by Western blotting with a series of PTM-specific antibodies. In addition to inducing
protein aggregation and denaturation, roasting may facilitate change in their PTM pattern and relative
profiling. We have shown that Ara h 1 is the most modified major allergen in both samples in terms
of modification versatility and extent. The most frequent PTM was methionine oxidation, especially
in roasted samples. PTMs uniquely found in roasted samples were hydroxylation (Trp), formylation
(Arg/Lys), and oxidation or hydroxylation (Asn). Raw and roasted peanut extracts did not differ
in the binding of IgE from the serum of peanut-sensitised individuals done by ELISA. This study
provides a better understanding of how roasting impacts the PTM profile of major peanut allergens

One of the key characteristics of contemporary competencies is interdisciplinarity, that is, extension beyond the framework of traditional school subjects, whereby children acquire knowledge that allows them to actively fulfill their civic roles. Inter-subject competencies as defined by the Law on Primary Education and Upbringing in Serbia include a responsible attitude towards the environment (Law on Primary Education and Upbringing, 2021). Therefore, responsible environmental behavior is one of the desired outcomes of the process of education. Likewise, it is an indicator of the wider construct referred to in the literature as environmental literacy.

AB  - C-phycocyanin (C-PC), the major protein of cyanobacteria Arthrospira platensis, is a blue
pigment that primarily transfers energy during photosynthesis.It has diverse
biotechnological applications since it can be used in nutraceutical, cosmetics,
pharmaceutical industries, and biomedical research.Its intensive blue colour and strong
antioxidant activity give C-PC significant potential to replace synthetic colourants in the
food industry. However, thermal treatment of food has detrimental effects on C-PC colour
due to sensitivity to higher temperatures; therefore,the application of this natural colourant
in food and other products is limited. Hence, improving C-PC stability is the major
challenge for successful application in food and beverages colouring. In the light of this,we
aim to investigate the thermal stability of C-PC in the presence of selected sugars (glucose,
fructose and sucrose), commonly used in the food industry. Ex-situabsorption
spectrophotometryshowed that 18% solution (w/v) of glucose, sucrose and fructose at pH
7,upon incubation at 65℃, exhibit 91.4, 52.9 and 52.5% of colour preservation,
respectively.In situ fluorescence measurements revealed that free C-PC has a melting point
of 55.4°C, while the presence of glucose and sucrose increases the melting point of C-PC
to 64.4 and 61.4°C, respectively. On the other hand, fructose does not significantly
influence the C-PC melting point. These results show that the thermal stability ofthe CPCsolution is substantially increased in the presence of sugars, while the type of sugar
significantly determines the extent of the stabilisation effect. Overall, our study provides
the strategy for enhancing the application potential of C-PC as natural food colourant,
providing a food product with vivid blue colour and substantial antioxidant activities.

AB  - Fotosintetski fikobilinski proteini (PBP) cijanobakterija (modro-zelene alge) i crvenih algi sve se više koriste u industriji hrane (živopisna boja) i biomedicini (snažna bioaktivna svojstva). Jedinstvena fizičko-hemijska svojstva PBP pre svega potiču od neproteinskog dela molekula, tj. kovalentno vezanih (jedna ili više) tetrapirolnih fikobilinskih hromofora. Ovi obojeni proteini poseduju obećavajući potencijal da zamene sintetičke kolorante u prehrambenoj industriji. Međutim, neophodni termalni tretmani hrane bi imali štetan efekat na strukturu ovih proteina, samim tim i na njihovu boju, što značajno ograničava primenu ovih proteina u industrijske svrhe.

abstract = "Fotosintetski fikobilinski proteini (PBP) cijanobakterija (modro-zelene alge) i crvenih algi sve se više koriste u industriji hrane (živopisna boja) i biomedicini (snažna bioaktivna svojstva). Jedinstvena fizičko-hemijska svojstva PBP pre svega potiču od neproteinskog dela molekula, tj. kovalentno vezanih (jedna ili više) tetrapirolnih fikobilinskih hromofora. Ovi obojeni proteini poseduju obećavajući potencijal da zamene sintetičke kolorante u prehrambenoj industriji. Međutim, neophodni termalni tretmani hrane bi imali štetan efekat na strukturu ovih proteina, samim tim i na njihovu boju, što značajno ograničava primenu ovih proteina u industrijske svrhe.

AB  - Еколошки проблеми са којима се сусреће наша земља су бројни, а последице деградације животне средине одражавају се на здравље и квалитет живота грађана. У том контексту, питање еколошког образовања и васпитања и еколошке писмености добија све већи значај. У овом пилот-истраживању испитана је могућност за примену међународног инструмента за одређивање нивоа еколошке писмености Middle School Environmental Literacy Survey (MSELS) на популацију ученика завршних разреда основне школе у Србији. Овај инструмент мери еколошку писменост кроз четири компоненте: еколошко знање, афективни однос према животној средини, когнитивне вештине и проеколошко понашање, са одговарајућим супкомпонентама. Садржај инструмента анализиран је у контексту програма наставе и учења за предмете Биологија и Грађанско васпитање, као и образовних стандарда за крај обавезног образовања за наставни предмет Биологија. У истраживању је коришћен анкетни метод, а за анализу података примењена је дескриптивна статистика. Подаци су прикупљени на узорку ученика седмог разреда основне школе (N=111) са територије Београда. Уз то, одржани су разговори са ученицима у пет групних интервјуа ради провере јасноће садржаја инструмента. Установљено је да је примена овог инструмента примерена по више основа: 1) инструмент је добро теоријски утемељен; 2) инструмент је заснован на целовитом приступу мерењу еколошке писмености; 3) инструмент је адекватан са становишта програма наставе и учења нашег образовног система и 4) инструмент има солидне метријске карактеристике. Поузданост инструмента у целини је ,87. Највиши скор испитани ученици остварили су на компоненти афективног односа према животној средини, у односу на остале мерене компоненте, као и у односу на две државе са којима поредимо добијене резултате (САД, Грчка). Најнижи скор забележен је на скали основних еколошких знања, и закључено је да ученици нису у потпуности овладали знањима која су предвиђена образовним стандардима у настави биологије.

AB  - The environmental issues that our country is faced with are numerous, while the consequences of environmental degradation affect the health and the quality of life of our citizens. In this context, the issue of environmental education and environmental literacy is gaining momentum. In the present pilot research we examined the possibility of applying an international instrument for determining the level of environmental literacy, the Middle School Environmental Literacy Survey (MSELS), on a population of students in the higher grades of elementary school in Serbia. This instrument measures the environmental literacy using four components: environmental knolwedge, environmental affect, cognitive skills, and environmental behavior, together with corresponding sub-components. The content of the instrument was analyzed in the context of Biology and Civic education curricula as well as educational standards for the end of compulsory education for the subject Biology. Survey method was used in the research, while the data were analyzed using descriptive statistics. The data were collected on a sample of the seventh-grade elementary school students (N=111) from the territory of Belgrade. In addition, five group interviews were conducted with the students to check the clarity of the content of the instrument. The researchers established that the implementation of this instrument is adequate on several grounds: 1) the instrument is well-grounded in theory; 2) the instrument is based on a comprehensive approach to environmental literacy measurement; 3) the instrument is adequate in terms of the teaching and learning program in our education system and 4) the instrument has solid metric features. An overall reliability of the instrument is ,87. The respondents had the highest score in the component of affective attitudes towards environment, relative to other measured components, as well as relative to two countries used for comparing the results (USA, Greece). The lowest score was identified on the scale of the basic environmental knowledge, and the conclusion is that students did not fully master the knowledge envisaged in the educational standards for Biology lessons. The main disadvantage of the instrument is the time required for filling it out due to the amount of the content.

AB  - Нови корона вирус (SARS CoV-2) је нови инфективни агенс за хуману популацију и веома је брзо детектован у великом броју земаља. Брзо ширење, одсуство имунитета на овај вирус и одсуство поузданих тестова за детекцију вируса у тренутку избијања пандемије су болест изазвану овим вирусом брзо претворили у здравствени и друштвени проблем највишег приоритета на глобалном нивоу. Иако су највеће биотехнолошке компаније убрзано почеле са развојем и масовном производњом дијагностичких тестова и вакцина, њихова доступност у тренуцима највеће потражње је и даље недовољна, а цене истих су лимитирајући фактор за бољу контролу болести и ширења пандемије. Тестови имају и своја ограничења, посебно када су у питању антигенски тестови, тако да се и даље ради на унапређењу осетљивости истих. У фокусу наших истраживања је развој дијагностичких и серолошких тестова за COVID-19. Дијагностички тестови детектују делове вируса: генетског материјала вируса , односно протеинске компоненте вируса. Серолошки тестови који детектују присуство антитела на протеине вируса. Важна компенента ових тестова је рекомбинанто произведен протеин. Истраживачки тим Хемијског факултета је до сада произвео рекомбинантне протеине шиљка и нуклеокапсида за потребе развоја серолошког теста и N протеин високе чистоће на великој скали за потребе добијања специфичких антитела и развоја антигенског теста. Добијена високо специфична поликлонска антитела на N протеин вируса из имунизованих животиња, биће употребљена за дизајн основног сендвич ЕЛИСА теста за детекцију SARS CoV-2 вируса на бази препознавања N-протеина вируса.  Oчекује се даље унапређење осетљивости теста применом различитих техника, као што су имобилисана специфична антитела на принципу имуноафинитетног ЕЛИСА теста што ће омогућити хватање вирусних антигена у хуманим телесним течностима попут крви, урина и пљувачке, и њихово даље концентрисање, што са једне стране повећава могућност за тачан резултат а са друге стране шири репертоар врсте узорака.

AB  - RT-PCR remains the primary method of diagnosing SARS-CoV-2. Serological diagnosis of COVID-19 is simple and does not require complex techniques and equipment, rendering it suitable for rapid detection and massive screening. However, serological tests cannot confirm SARS-CoV-2, and results will be false negative when antibody concentrations fall below detection limit. Serological testing is important method for diagnosis of severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) infection. Antigen-based tests show high specificity, but sensitivity is relatively low. For development and further improvement of both serological and antigen-based tests, availability of recombinantly producted SARS CoV-2 antigens is needed and during the periods of high demend in the pandemic, it was a limited factor both for research and diagnostic tests production by national producers of tests. Nucleocapsid (N) protein is the most abundant virus derived protein and strong immunogen. We aimed to find its efficient, low-cost production. SARS-CoV-2 recombinant fragment of nucleocapsid protein (rfNP; 58-419 aa) was expressed in E. coli in soluble form, purified and characterized biochemically and immunologically. Purified rfNP has secondary structure of full-length recombinant N protein, with high percentage of disordered structure (34.2%) and of beta-sheet (40.7%). rfNP was tested in immunoblot using sera of COVID-19 convalescent patients. Cost-effective approach for soluble recombinant N protein fragment production was developed, with reliable IgG and IgM antibodies detection of SARS-CoV-2 infection. ELISA was optimized with sera of RT-PCR confirmed positive symptomatic patients and healthy individuals. IgG detection sensitivity was 96% (47/50) and specificity 97% (67/68), while IgM detection was slightly lower (94% and 96.5%, respectively). Application of serological ELISA for seropositivity detection in 200 allergic children in comparison to non-allergic did not show a bias towards any of the tested groups.  Furthermore, we have optimized production of rfNP at a large scale to raise specific antibodies to N-protein in rabbit and mice and develop an in house ELISA for quantification of N protein in biological fluids. Test was clinically validated in 200 PCR positive patients and showed a sensitivity of around 50%.

AB  - The accurate diagnosis of people with suspected infection with the SARS-CoV-2 is
essential to curb the global spread of COVID-19. The presence of SARS-CoV-2 can be
detected by RT-PCR (it detects RNA of the virus) or by the presence of viral antigens in
biological fluids in ELISA or similar techniques using antibodies developed in animals.
The aim of the study was the establishment of a quantitative polyclonal sera-based test for
routine measurement of the concentration of SARS CoV-2 nucleocapsid protein using
absorbance measurement in a standard 96-well microtiter plate. For the purposes of the test
development, recombinant N protein was produced and used for the production of mice
and rabbit antisera. Produced antisera were purified and titer was determined. High-affinity
polyclonal N-protein specific antisera were used for N-protein specific ELISA test
development. The test is based on mice polyclonal sera adhered to microtiter plate bottom
for the capture of the N protein from the specimen. Various concentrations of the
recombinant N-protein were used to generate a standard curve for protein quantification.
The N-protein bound to the mice antibodies was detected with rabbit polyclonal sera and
anti-rabbit antibody coupled to an enzyme that provides spectrophotometric measurement.
We have successfully developed the prototype ELISA for the quantification of N-protein
with the detection limit being in the range of ng/mL. The average LOD value for the
prototype ELISA was determined to be 9.2 ng/mL, while the average LOQ value was
10.2 ng/mL. We have demonstrated that produced polyclonal antisera are suitable for the
detection of N-protein with affinity and specificity similar to, or better than commercial
antibodies. Furthermore, the prototype ELISA can be used with satisfactory confidence for
quantification of the N-protein in protein-rich samples, similar to human sera.

AB  - Nakon skoro tri godine od pojave SARS-CoV-2 virusa u kineskom gradu Vuhanu, koji se veoma brzo proširio i na ostatak sveta, izazivajući najgoru pandemiju još od kraja Prvog svetskog rata i tzv. Španske groznice, zahvaljujući biomedicinskim istraživanjima, danas raspolažemo širokim spektrom vakcina protiv COVID-19. Vakcine protiv COVID-19 uključuju tradicionalne - inaktivirane vakcine, kao i vektorske vakcine i mRNA vakcine koje predstavljaju novu generaciju vakcina i platformu za mnoga istraživanja i proizvodnju drugih proizvoda zasnovanih na mRNA tehnologiji. Takođe, raspolažemo i brojnim serološkim testovima, kako za kvalitativnu tako i za semi-kvantitativnu i kvantitativnu analizu. Navedeni testovi u kratkom vremenskom roku daju rezultate koji mogu biti iskorišćeni u dijagnostici, praćenju kontakata i za epidemiološke studije.
Ova studija je rađena u Institutu za virusologiju, vakcine i serume "Torlak", u Odseku za naučno-istraživački rad i ima za cilj da pokaže mogućnost primene antigena SARS-CoV-2 virusa, proizvedenih rekombinantnom tehnologijom, u praćenju SARS-CoV-2 specifičnog imunskog odgovora. U urađenim istraživanjima korišćen je receptor vezujući domen (engl. receptor-binding domain, RBD) spike (S) proteina SARS-CoV-2.

abstract = "Nakon skoro tri godine od pojave SARS-CoV-2 virusa u kineskom gradu Vuhanu, koji se veoma brzo proširio i na ostatak sveta, izazivajući najgoru pandemiju još od kraja Prvog svetskog rata i tzv. Španske groznice, zahvaljujući biomedicinskim istraživanjima, danas raspolažemo širokim spektrom vakcina protiv COVID-19. Vakcine protiv COVID-19 uključuju tradicionalne - inaktivirane vakcine, kao i vektorske vakcine i mRNA vakcine koje predstavljaju novu generaciju vakcina i platformu za mnoga istraživanja i proizvodnju drugih proizvoda zasnovanih na mRNA tehnologiji. Takođe, raspolažemo i brojnim serološkim testovima, kako za kvalitativnu tako i za semi-kvantitativnu i kvantitativnu analizu. Navedeni testovi u kratkom vremenskom roku daju rezultate koji mogu biti iskorišćeni u dijagnostici, praćenju kontakata i za epidemiološke studije.
Ova studija je rađena u Institutu za virusologiju, vakcine i serume "Torlak", u Odseku za naučno-istraživački rad i ima za cilj da pokaže mogućnost primene antigena SARS-CoV-2 virusa, proizvedenih rekombinantnom tehnologijom, u praćenju SARS-CoV-2 specifičnog imunskog odgovora. U urađenim istraživanjima korišćen je receptor vezujući domen (engl. receptor-binding domain, RBD) spike (S) proteina SARS-CoV-2.

AB  - The accumulation of microplastics in marine organisms is an emerging concern. Due to trophic transfer, the
safety of seafood is under investigation in view of the potential negative effects of microplastics on human health.
In this study, market samples of Manila clams (Ruditapes philippinarum) from South Korea were segregated into
two groups of considerably different size (p < 0.05), namely small clams with shell length of 40.69 ± 3.97 mm,
and large clams of shell length 51.19 ± 2.86 mm. Comparative profiling of the number, size, shape, and polymer
type of microplastics were performed using μFTIR imaging and Nile red staining. Overall, μFTIR detected only
1559 microplastics while 1996 microplastics were counted based on staining from 61 Manila clams (30 small and
31 large), leading to an overestimation of 18 to 75 %. Comparable microplastics concentration, based on μFTIR,
were observed at 2.70 ± 1.66 MP/g or 15.64 ± 9.25 MP/individual for the small samples, and 3.65 ± 1.59 MP/g
or 41.63 ± 16.90 MP/individual for the large ones (p > 0.05). Particle diameters of 20–100 μm was the most
dominant, accounting for 44.6 % and 46.5 % of all microplastics from the small and large groups, respectively.
Particles, with a circularity (resemblance to a circle) value between 0.6 and 1.0, were the most prevalent, fol-
lowed by fragments and fibers. At least 50 % of microplastics from the small and large samples were polystyrene,
making it the most abundant polymer type. Despite the substantial difference in the size of the animals, only a
weak to moderate correlation was observed between microplastics content and the physical attributes of the
clams such as shell length and weight, (soft) tissue weight, and total weight (Spearman's coefficient < 0.5). The
estimated intake of microplastics by the Korean population was 1232 MP/person/year via small clams, 1663 MP/
person/year via large clams, and 1489 MP/person/year via clams independent of size.
