AB  - The rapid escalation of plastic waste accumulation presents a significant threat of the modern world, demanding an immediate solution. Over the last years, utilization of the enzymatic machinery of various microorganisms has emerged as an environmentally friendly asset in tackling this pressing global challenge. Thus, various hydrolases have been demonstrated to effectively degrade polyesters. Plastic waste streams often consist of a variety of different polyesters, as impurities, mainly due to wrong disposal practices, rendering recycling process challenging. The elucidation of the selective degradation of polyesters by hydrolases could offer a proper solution to this problem, enhancing the recyclability performance. Towards this, our study focused on the investigation of four bacterial polyesterases, including DaPUase, IsPETase, PfPHOase, and Se1JFR, a novel PETase-like lipase. The enzymes, which were biochemically characterized and structurally analyzed, demonstrated degradation ability of synthetic plastics. While a consistent pattern of polyesters’ degradation was observed across all enzymes, Se1JFR stood out in the degradation of PBS, PLA, and polyether PU. Additionally, it exhibited comparable results to IsPETase, a benchmark mesophilic PETase, in the degradation of PCL and semi-crystalline PET. Our results point out the wide substrate spectrum of bacterial hydrolases and underscore the significant potential of PETase-like enzymes in polyesters degradation.

AB  - Nonsteroidal anti-inflammatory drugs (NSAIDs) alleviate inflammation and pain through the inhibition of cyclooxygenase (COX) enzymes. Besides these widely recognized therapeutic utilizations, NSAIDs have been reported to display moderate antimicrobial activity and enhance antimicrobial efficacy when administered in combination with commercial antimicrobial drugs. In the present study, we designed novel potential antimicrobial agents by linking some NSAIDs (ibuprofen, flurbiprofen, and naproxen) to various azole rings (pyrazole, imidazole, triazole, and benzimidazole) via hydrazone functionality. The hydrazone linker was introduced into the chemical scaffold of the title molecules by the reaction between hydrazides obtained from NSAIDs and in-house synthesized azole-carrying benzaldehydes. The structures of the target compounds were elucidated by a combination of spectral methods. The NOESY spectra and stereochemical analyses performed using DFT method confirmed the presence of the target molecules as a mixture of E(C=N)-E(N-N)-synperiplanar and E(C=N)-E(N-N)-antiperiplanar conformers in DMSO-d6 solution. 1H and 13C NMR chemical shift values in DMSO were calculated using the GIAO method and compared with the experimental NMR data. Finally, some derivatives were demonstrated to inhibit Candida albicans filamentation and/or bacterial communication system known as quorum sensing. For COX inhibitor-azole hybrids with antimicrobial potency, naproxen appeared to be the most appropriate NSAID, while bulky benzimidazole was not found as a preferable azole ring.

AB  - Astrocytes are the main homeostatic cells in the central nervous system, with the unique ability to transform from quiescent into a reactive state in response to pathological conditions by reacquiring some precursor properties. This process is known as reactive astrogliosis, a compensatory response that mediates tissue damage and recovery. Although it is well known that SOX transcription factors drive the expression of phenotype-specific genetic programs during neurodevelopment, their roles in mature astrocytes have not been studied extensively. We focused on the transcription factors SOX2 and SOX9, shown to be re-expressed in reactive astrocytes, in order to study the reactivation-related functional properties of astrocytes mediated by those proteins. We performed an initial screening of SOX2 and SOX9 expression after sensorimotor cortex ablation injury in rats and conducted gain-of-function studies in vitro using astrocytes derived from the human NT2/D1 cell line. Our results revealed the direct involvement of SOX2 in the reacquisition of proliferation in mature NT2/D1-derived astrocytes, while SOX9 overexpression increased migratory potential and glutamate uptake in these cells. Our results imply that modulation of SOX gene expression may change the functional properties of astrocytes, which holds promise for the discovery of potential therapeutic targets in the development of novel strategies for tissue regeneration and recovery.

AB  - 22q11.2 deletion syndrome (22q11.2DS), the most frequent microdeletion syndrome in humans, is related to a high risk of developing neurodevelopmental disorders. About 95% of patients with 22q11.2DS have speech and language impairments. Global articulation, story generation, and verbal memory tests were applied to compare articulatory characteristics of speech sounds, spontaneous language abilities, and immediate verbal memory between four groups of Serbian-speaking children: patients with 22q11.2DS, children with clinical presentation of 22q11.2DS that do not have the microdeletion, children with non-syndromic congenital heart defects, and their peers with typical speech–sound development. The obtained results showed that children with this microdeletion have impaired articulation skills and expressive language abilities. However, we did not observe weaker receptive language skills and immediate verbal memory compared to healthy controls. Children with 22q11.2DS should be considered a risk category for the development of speech–sound pathology and expressive language abilities. Since speech intelligibility is an instrument of cognition and adequate peer socialization, and language impairment in school-aged children with 22q11DS might be an indicator of increased risk for later psychotic symptoms, patients with 22q11.2 microdeletion should be included in a program of early stimulation of speech–language development immediately after diagnosis is established.

New concept for treatment of glycogen storage disease Ib and diabetes mellitus type 2: small molecule compounds able to adjust glucose level through binding glucose-6-phospate translocase (GlucoAdjust)

AB  - GlucoAdjust project aims to solve fast-growing health challenges important for the society,
namely it will focus on discovery of new treatments for one rare disease glycogen storage
disease type Ib (GSD Ib) and one common disease diabetes mellitus type 2 (DM type 2). We
propose a completely new concept based on the identification of small molecule (SM)
compounds able to directly bind to glucose-6-phospate translocase (G6PT) and thus fine-tune
glucose level. To tackle these challenges, an interdisciplinary international team will screen large
library of SMs combining in silico and in vitro approaches and identify SMs that directly bind to
G6PT. SMs able to stabilize G6PT and increase its function thus correcting hypoglycemia are
potential drugs for GSD Ib. On the other hand, SMs that inhibit G6PT may be used to induce
hypoglycemia in DM type 2 treatment. To obtain highly functional results of testing SMs in vitro,
human hepatocyte models for GSD Ib and DM type 2 as well as controls will be developed
(differentiated from human healthy and GSD Ib iPSC and diabetic adipose stem cells). For the
first time, whole transcriptome of human GSD Ib hepatocytes will be used to delineate molecular
processes disturbed due to G6PT deficiency. As a result, RNA hallmarks of GSD Ib phenotype will
be determined and used for evaluation of SMs’ effect in both models. To be efficient for GSD Ib,
SMs will have to revert GSD Ib phenotype into normal. The key to discover satisfactorily
effective, yet sufficiently mild inhibitor for DM type 2 will be to avoid hallmarks representing
GSD Ib phenotype. Thus, a revolutionary concept of using GSD Ib as a model of hypoglycemia to
better optimize DM type 2 treatment is proposed here. Results will be openly disseminated to
make a wide scientific, educational, social and economic impacts. GlucoAdjust anticipates
innovative results with a potential to be further translated into drugs able to improve lives of
people with GSD Ib and DM type 2 worldwide.

library of SMs combining in silico and in vitro approaches and identify SMs that directly bind to
G6PT. SMs able to stabilize G6PT and increase its function thus correcting hypoglycemia are
potential drugs for GSD Ib. On the other hand, SMs that inhibit G6PT may be used to induce
hypoglycemia in DM type 2 treatment. To obtain highly functional results of testing SMs in vitro,
human hepatocyte models for GSD Ib and DM type 2 as well as controls will be developed
(differentiated from human healthy and GSD Ib iPSC and diabetic adipose stem cells). For the
first time, whole transcriptome of human GSD Ib hepatocytes will be used to delineate molecular
processes disturbed due to G6PT deficiency. As a result, RNA hallmarks of GSD Ib phenotype will
be determined and used for evaluation of SMs’ effect in both models. To be efficient for GSD Ib,
SMs will have to revert GSD Ib phenotype into normal. The key to discover satisfactorily
effective, yet sufficiently mild inhibitor for DM type 2 will be to avoid hallmarks representing
GSD Ib phenotype. Thus, a revolutionary concept of using GSD Ib as a model of hypoglycemia to
better optimize DM type 2 treatment is proposed here. Results will be openly disseminated to
make a wide scientific, educational, social and economic impacts. GlucoAdjust anticipates
innovative results with a potential to be further translated into drugs able to improve lives of
people with GSD Ib and DM type 2 worldwide.",

AB  - Antimicrobial resistance is a global threat, leading to an alarming increase in the prevalence of bacterial infections that can no longer be treated with available antibiotics. The World Health Organization estimates that by 2050 up to 10 million deaths per year could be associated with antimicrobial resistance, which would equal the annual number of cancer deaths worldwide. To overcome this emerging crisis, novel anti-bacterial compounds are urgently needed. There are two possible approaches in the fight against bacterial infections: a) targeting structures within bacterial cells, similar to existing antibiotics; and/or b) targeting virulence factors rather than bacterial growth. Here, for the first time, we provide a comprehensive overview of the key steps in the evaluation of potential new anti-bacterial and/or anti-virulence compounds. The methods described in this review include: a) in silico methods for the evaluation of novel compounds; b) anti-bacterial assays (MIC, MBC, Time-kill); b) anti-virulence assays (anti-biofilm, anti-quorum sensing, anti-adhesion); and c) evaluation of safety aspects (cytotoxicity assay and Ames test). Overall, we provide a detailed description of the methods that are an essential tool for chemists, computational chemists, microbiologists, and toxicologists in the evaluation of potential novel antimicrobial compounds. These methods are cost-effective and have high predictive value. They are widely used in preclinical studies to identify new molecular candidates, for further investigation in animal and human trials.

AB  - In contrast to humans, zebrafish have a remarkable ability to regenerate their hearts after injury, while both humans and zebrafish efficiently repair the wounded skeletal muscle. Common players in these two processes might represent potential targets for the development of efficient therapies to stimulate human heart to regenerate after injury. We identified ankrd1a expression to be upregulated in both regenerating zebrafish hearts and in repairing skeletal muscle. Its mammalian homolog ANKRD1/CARP encodes a stress responsive cardiac ankyrin repeat protein involved in transcriptional regulation, sarcomere assembly and mechanosensing. Using a TgBAC(ankrd1a:EGFP) line, we showed that activation of ankrd1a in cryoinjured heart is restricted to border zone cardiomyocytes, implicating this gene in dedifferentiation and proliferation of regenerating cardiomyocytes. After stab wound injury of skeletal muscle expression of the fluorescent reporter was observed from 3 dpi, when new EGFP-positive muscle cells emerged inside the injury zone. At later time points, EGFP-positive myofibers were visible in the deeper tissue layers, concomitant with active repair of the injured tissue. In cryoinjured skeletal muscle, strong activation of ankrd1a was also observed in myofibers adjacent to the injury, and in those on uninjured side. Detection of the transgene in both newly formed myofibers that invade the wound and in the apparently uninjured tissue surrounding the injury suggests the role of ankrd1a in skeletal muscle tissue repair and adaptive processes in uninjured myofibers surrounding the injury site. Our results implicate ankrd1a in zebrafish muscle regeneration, repair and remodeling, promoting it as an attractive target for translational studies, as a player in muscle healing and as a sensor of stressed muscle.

AB  - Echinococcus, tapeworms of the Taeniidae family, can infect humans and animals and cause
serious, even lethal disease. Global population genetics data suggests that disease presentation,
severity, immune response, as well as relative host susceptibility and resistance to infection
depend on the species, genotype and haplotype. The species of significant clinical relevance in
Europe are E. granulosus, the causative agent of cystic echinococcosis (CE) and E. multilocularis,
which causes the most severe disease, alveolar echinococcosis (AE). Analysis of the population
genetics of Echinococcus is an ongoing effort in some parts of Europe, while the Balkans
represent a significant knowledge gap. This project aims to comprehensively survey the entire
transmission cycle consisting of intermediate and definitive animal hosts and the environment
using sample processing and analytical methods which have been standardized, validated and
harmonized at the EU level to obtain high quality population genetics data via mitochondrial gene
(cox1 and nad1) sequencing and characterization of the EmsB microsatellite from single eggs,
worms and protoscolices. As a main novelty, comprehensive Echinococcus population genetics
data, through a survey of underexplored reservoirs with a high transmission capacity to humans,
will be systematized and graphically displayed through an interactive bioinformatics database,
WormProfiler, with a user interface tailored to physicians and veterinarians. The impact of the
project is the translation of population genetics data to physicians and veterinarians, key
stakeholders for transmission prevention to facilitate education of the public and raise awareness
of echinococcosis. The project should provide the insight into the genetic diversity of
Echinococcus and identification of transmission foci, as well as a software supported framework
for systematic surveillance and future development of targeted transmission control actions to
reduce echinococcosis case burden.

AB  - Introduction: Lipid nanovesicles associated with bioactive phytochemicals from spruce needle homogenate (here called nano-sized
hybridosomes or nanohybridosomes, NSHs) were considered.
Methods: We formed NSHs by mixing appropriate amounts of lecithin, glycerol and supernatant of isolation of extracellular vesicles
from spruce needle homogenate. We visualized NSHs by light microscopy and cryogenic transmission electron microscopy and
assessed them by flow cytometry, dynamic light scattering, ultraviolet–visual spectroscopy, interferometric light microscopy and liquid
chromatography–mass spectrometry.
Results: We found that the particles consisted of a bilayer membrane and a fluid-like interior. Flow cytometry and
interferometric light microscopy measurements showed that the majority of the particles were nano-sized. Dynamic light
scattering and interferometric light microscopy measurements agreed well on the average hydrodynamic radius of the
particles Rh (between 140 and 180 nm), while the concentrations of the particles were in the range between 1013 and
1014/mL indicating that NSHs present a considerable (more than 25%) of the sample which is much more than the yield of
natural extracellular vesicles (EVs) from spruce needle homogenate (estimated less than 1%). Spruce specific lipids and
proteins were found in hybridosomes.
Discussion: Simple and low-cost preparation method, non-demanding saving process and efficient formation procedure suggest that
large-scale production of NSHs from lipids and spruce needle homogenate is feasible.
Plain Language Summary: Cells shed into their exterior nanoparticles (here referred to as extracellular vesicles – EVs) that
are free to move, reach distant cells and are taken up by them. As they carry bioactive constituents, EVs may have important
impact on the recipient cells. The mechanisms of EV formation and mediation can be employed in designing therapeutic,
prophylactic and diagnostic methods for various medical issues. EVs can be harvested from biological samples; however,
their yield is small,12 and there are potential side effects. Artificial vesicles – liposomes – have high yield; however, in vivo,
they can be degraded before reaching the target and their reproducibility is yet insufficient. In order to combine advantages of
both types of nanoparticles, we have composed nanohybridosomes (NSHs) from soya lecithin, water and supernatant of
isolation of EVs from spruce needle homogenate, visualized them by cryogenic electron microscopy and characterized them
with respect to their size, concentration and protein/nucleic acid content. We have applied a recently developed interferometric light microscopy to determine the hydrodynamic radius and the concentration of EVs. We found that the majority of
composed particles are nano-sized and that they enclose more than 25% of the incoming volume of liquid, which is considerably more than about 1% that can be harvested by isolation of EVs from spruce needle homogenate by (ultra)
centrifugation

AB  - The discovery and engineering of novel biocatalysts capable of depolymerizing polyethylene terephthalate (PET) have gained significant attention since the need for green technologies to combat plastic pollution has become increasingly urgent. This study focuses on the development of novel substrates that can indicate enzymes with PET hydrolytic activity, streamlining the process of enzyme evaluation and selection. Four novel substrates, mimicking the structure of PET, were chemically synthesized and labeled with fluorogenic or chromogenic moieties, enabling the direct analysis of candidate enzymes without complex preparatory or analysis steps. The fluorogenic substrates, mUPET1, mUPET2, and mUPET3, not only identify enzymes capable of PET breakdown but also differentiate those with exceptional performance on the polymer, such as the benchmark PETase, LCCICCG. Among the substrates, the chromogenic p-NPhPET3 stands out as a reliable tool for screening both pure and crude enzymes, offering advantages over fluorogenic substrates such as ease of assay using UV–vis spectroscopy and compatibility with crude enzyme samples. However, ferulic acid esterases and mono-(2-hydroxyethyl) terephthalate esterases (MHETases), which exhibit remarkably high affinity for PET oligomers, also show high catalytic activity on these substrates. The substrates introduced in this study hold significant value in the function-based screening and characterization of enzymes that degrade PET, as well as the the potential to be used in screening mutant libraries derived from directed evolution experiments. Following this approach, a rapid and dependable assay method can be carried out using basic laboratory infrastructure, eliminating the necessity for intricate preparatory procedures before analysis.

The fluorogenic substrates, mUPET1, mUPET2, and mUPET3, not only identify enzymes capable of PET breakdown but also differentiate those with exceptional performance on the polymer, such as the benchmark PETase, LCCICCG. Among the substrates, the chromogenic p-NPhPET3 stands out as a reliable tool for screening both pure and crude enzymes, offering advantages over fluorogenic substrates such as ease of assay using UV–vis spectroscopy and compatibility with crude enzyme samples. However, ferulic acid esterases and mono-(2-hydroxyethyl) terephthalate esterases (MHETases), which exhibit remarkably high affinity for PET oligomers, also show high catalytic activity on these substrates. The substrates introduced in this study hold significant value in the function-based screening and characterization of enzymes that degrade PET, as well as the the potential to be used in screening mutant libraries derived from directed evolution experiments. Following this approach, a rapid and dependable assay method can be carried out using basic laboratory infrastructure, eliminating the necessity for intricate preparatory procedures before analysis.",

AB  - SalmonellaEnteritidis is the most commonly reported pathogen for foodborne illness outbreaks in both underdeveloped and developed regions. S. Enteritidis biofilms, which form on various food contact surfaces, are resistant to conventional physical and chemical cleaning and disinfection procedures routinely used in food processing. The aim of this study was to identify novel, industrially applicable enzymes that are active against S. Enteritidis biofilms. We describe the properties and anti-biofilm activity of heterologously expressed β-glucosidase B derived from the environmental strain Microbacterium sp. BG28 (BglB-BG28) collected from gills of bream fish. The enzyme inhibited adhesion and the early stages of biofilm formation in clinical isolates of S. Enteritidis. At a concentration of 200 μg/mL, BglB-BG28 effectively reduced biofilm formation, by decreasing biofilm biomass by 50% and metabolic activity within biofilms by 80%. The enzyme reduced the formation of air-liquid biofilms on various surfaces, including plastic, glass and metal, as observed by fluorescence microscopy. BglB-BG28 inhibited biofilm formation in Escherichia coli, another important food pathogen that also forms cellulose-rich biofilms. Using o-NPG as substrate, the enzyme showed activity at temperatures up to 50 °C and in a pH range between 4 and 8, high tolerance to sodium chloride and glucose, and compatibility with nonionic detergents. Importantly, no toxicity was observed in the model system Caenorhabditis elegans even at an enzyme concentration of 1 mg/mL. These results suggest that the β-glucosidase BglB-BG28 is a promising candidate for the development of a new enzyme-based disinfection protocol that can be used in food processing facilities.

AB  - During 2024, IMGGE researchers will continue exploring following areas:
- human molecular genetics and genomics,
- microbiology and ecology of microorganisms,
- plant molecular biology.
IMGGE researchers will focus on studying molecular mechanisms responsible for the
occurrence of selected rare and non-contagious diseases, as well as on identification of
molecular markers important for diagnosis, prognosis, therapy and prevention. Disease
modeling methodology will be developed using in vitro model systems (2D and 3D primary and
permanent cell lines, induced pluripotent stem cells) and in vivo model systems that include
different animal models. These stydies will aim at discovering the causes of the disease,
identifying new therapeutic targets, testing new therapeutics as well as individual response to
existing therapeutics.
During 2024, the existing IMGGE collection of microorganisms will be further expanded with
new isolates (industrial microorganisms, clinically relevant pathogens, and bacteriophages), and
IMGGI collaborators will devote themselves to studying the antimicrobial and antiviral potential
and application of new isolates, as well as mechanisms of resistance and virulence. The
genomes of selected microorganisms will be sequenced and analyzed to identify new genes of
interest, e.g. producers of bioactive proteins, enzymes and biosynthetic pathways.
Metagenomes of selected environmental or clinical samples will also be sequenced and
analyzed in order to study the biological diversity of complex communities of microorganisms.
When it comes to the molecular biology of plants, the response mechanisms of different model
organisms to abiotic and biotic stress will further be investigated. IMGGE researchers will
analyze the role of different proteins in maintaining cell homeostasis (eg LEA) and genome
stability (Ustilago maydis). The genomes, epigenomes and proteomes of the muscat flower will
be sequenced in order to study the response to stress.

AB  - Here, an artificial intelligence (AI)-based approach was employed to optimize the production of electrospun scaffolds for in vivo wound healing applications. By combining polycaprolactone (PCL) and poly(ethylene glycol) (PEG) in various concentration ratios, dissolved in chloroform (CHCl3) and dimethylformamide (DMF), 125 different polymer combinations were created. From these polymer combinations, electrospun nanofiber meshes were produced and characterized structurally and mechanically via microscopic techniques, including chemical composition and fiber diameter determination. Subsequently, these data were used to train a neural network, creating an AI model to predict the optimal scaffold production solution. Guided by the predictions and experimental outcomes of the AI model, the most promising scaffold for further in vitro analyses was identified. Moreover, we enriched this selected polymer combination by incorporating antibiotics, aiming to develop electrospun nanofiber scaffolds tailored for in vivo wound healing applications. Our study underscores three noteworthy conclusions: (i) the application of AI is pivotal in the fields of material and biomedical sciences, (ii) our methodology provides an effective blueprint for the initial screening of biomedical materials, and (iii) electrospun PCL/PEG antibiotic-bearing scaffolds exhibit outstanding results in promoting neoangiogenesis and facilitating in vivo wound treatment.

AB  - The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), responsible for the COVID-19 pandemic, has been evolving rapidly causing emergence of new variants and health uncertainties. Monitoring the evolution of the virus was of the utmost importance for public health interventions and the development of national and global mitigation strategies. Here, we report national data on the emergence of new variants, their distribution, and dynamics in a 3-year study conducted from March 2020 to the end of January 2023 in the Republic of Serbia. Nasopharyngeal and oropharyngeal swabs from 2,398 COVID-19-positive patients were collected and sequenced using three different next generation technologies: Oxford Nanopore, Ion Torrent, and DNBSeq. In the subset of 2,107 SARS-CoV-2 sequences which met the quality requirements, detection of mutations, assignment to SARS-CoV-2 lineages, and phylogenetic analysis were performed. During the 3-year period, we detected three variants of concern, namely, Alpha (5.6%), Delta (7.4%), and Omicron (70.3%) and one variant of interest—Omicron recombinant “Kraken” (XBB1.5) (<1%), whereas 16.8% of the samples belonged to other SARS-CoV-2 (sub)lineages. The detected SARS-CoV-2 (sub)lineages resulted in eight COVID-19 pandemic waves in Serbia, which correspond to the pandemic waves reported in Europe and the United States. Wave dynamics in Serbia showed the most resemblance with the profile of pandemic waves in southern Europe, consistent with the southeastern European location of Serbia. The samples were assigned to sixteen SARS-CoV-2 Nextstrain clades: 20A, 20B, 20C, 20D, 20E, 20G, 20I, 21J, 21K, 21L, 22A, 22B, 22C, 22D, 22E, and 22F and six different Omicron recombinants (XZ, XAZ, XAS, XBB, XBF, and XBK). The 10 most common mutations detected in the coding and untranslated regions of the SARS-CoV-2 genomes included four mutations affecting the spike protein (S:D614G, S:T478K, S:P681H, and S:S477N) and one mutation at each of the following positions: 5′-untranslated region (5’UTR:241); N protein (N:RG203KR); NSP3 protein (NSP3:F106F); NSP4 protein (NSP4:T492I); NSP6 protein (NSP6: S106/G107/F108 - triple deletion), and NSP12b protein (NSP12b:P314L). This national-level study is the most comprehensive in terms of sequencing and genomic surveillance of SARS-CoV-2 during the pandemic in Serbia, highlighting the importance of establishing and maintaining good national practice for monitoring SARS-CoV-2 and other viruses circulating worldwide.

The samples were assigned to sixteen SARS-CoV-2 Nextstrain clades: 20A, 20B, 20C, 20D, 20E, 20G, 20I, 21J, 21K, 21L, 22A, 22B, 22C, 22D, 22E, and 22F and six different Omicron recombinants (XZ, XAZ, XAS, XBB, XBF, and XBK). The 10 most common mutations detected in the coding and untranslated regions of the SARS-CoV-2 genomes included four mutations affecting the spike protein (S:D614G, S:T478K, S:P681H, and S:S477N) and one mutation at each of the following positions: 5′-untranslated region (5’UTR:241); N protein (N:RG203KR); NSP3 protein (NSP3:F106F); NSP4 protein (NSP4:T492I); NSP6 protein (NSP6: S106/G107/F108 - triple deletion), and NSP12b protein (NSP12b:P314L). This national-level study is the most comprehensive in terms of sequencing and genomic surveillance of SARS-CoV-2 during the pandemic in Serbia, highlighting the importance of establishing and maintaining good national practice for monitoring SARS-CoV-2 and other viruses circulating worldwide.

AB  - Spinal muscular atrophy (SMA) is the prevalent genetic cause of childhood mortality.  Pioneering treatments yield utmost advantages only within the presymptomatic phase,  underlining the medical and ethical significance of newborn screening. 
In 2022, the Centre for Human Molecular Genetics initiated a pilot study of the newborn  screening for SMA, working closely alongside the University Children’s Hospital Tirsova  and Association SMA Serbia. The aim was to lay the foundation for the implementation  of statewide newborn screening for SMA in Serbia by conducting screening for ~8000  infants from the Obstetrics and Gynaecology Clinic Narodni Front over the course of a  year. In the subsequent year, we expanded the initiative to include another maternity  hospital located outside Belgrade, introducing sample shipment via postal services and  extending screening accessibility to a greater number of infants. 
In the initial year, 6 950 newborns underwent testing, revealing SMA in two unrelated  infants. Subsequently, an older sibling of the first newborn, although asymptomatic at  the time, was also tested at the age of 16 months, and SMA diagnosis was confirmed  in this child as well. All three children received therapeutic interventions in <1 month  from birth. To date, they have exhibited no signs of SMA, and there have been no false 
negative outcomes among the newborns who tested negative during the screening. In
the second year, an additional 5 000 newborns underwent testing. As frontrunners in this field in Serbia, we orchestrated harmonized efforts across  various tiers of healthcare, established screening and diagnostic algorithms and  follow-up protocols. Our extensive efforts were primarily aimed at elevating awareness  among all stakeholders about the critical importance of early disease detection.  In this transformative journey, we transitioned from being isolated individuals and  visionaries who championed a singular idea to an entire community and nation that now  acknowledges the paramount significance of newborn screening. As a result, a total of  11 950 infants underwent testing during the 17-month pilot project, culminating in the  rapid incorporation of newborn screening for SMA into the national screening program,  effective as of September 14th 2023. 
Timely detection and treatment can transform SMA into a manageable condition, and  there is substantial evidence supporting its inclusion in state-wide screening programs.

AB  - Antimicrobial resistance (AMR) and air pollution have been identified as one of the most
serious threats to human health worldwide. The scarce data demonstrating their
interdependence indicates a need to obtain evidence from a broader global area, especially
from regions exposed to high air pollution. Considering that Serbia is a country struggling with
excessive antibiotics use and misuse, a high percentage of multidrug-resistant bacterial isolates,
and poor air quality, the Serbian capital Belgrade has been recognized as an interesting
research model for the effects of air pollution on the airborne transmission of AMR. After
optimization of air sampling and DNA extraction protocol, the air samples will be collected at
nine locations in the Belgrade metropolitan area selected according to air pollution level during
four seasons. The state-of-the-art shotgun metagenomic sequencing and bioinformatic analysis
of obtained sequences will provide information about microbial community composition of
airborne metagenomes. In addition, sequenced airborne metagenomes will be analyzed for the
abundance and diversity of resistomes (antibiotic and biocide/metal resistance genes) and
mobilomes using several databases and tools. Correlation analyses will offer us insight into the
effect of air pollution and seasonal variations on abundance and diversity of airborne
pathogens, resistome and mobilome in the Belgrade metropolitan area. In-depth approach of
the AirPollRes project will provide the first insights into intersection of AMR and air pollution in
the Belgrade metropolitan area, which is highly vulnerable to these health threats. As the
AirPollRes is a pioneering project in this field, the expected short-term impact is the
introduction of routine monitoring of pathogenic microbes and resistance determinants in the
air in Belgrade, while the longer-term impact will be reflected in the improvement of human
and animal health, allowing for a longer life with higher quality.

AB  - Dysregulated expression of the long non-coding RNA MALAT1 has been implicated in the pathogenesis and progression of a variety of cancers, including hematological malignancies, but it has been poorly investigated in chronic lymphocytic leukemia (CLL). In this study, the expression of MALAT1 was measured using a quantitative reverse-transcriptase polymerase chain reaction in the peripheral blood mononuclear cells of 114 unselected, newly diagnosed CLL patients in order to analyze its association with clinical, laboratory, and molecular patients’ characteristics at diagnosis, as well as its prognostic relevance. MALAT1 was found to be upregulated in CLL patients in comparison to healthy controls, and expression levels were not related to age, leukocyte, lymphocyte and platelet count, serum β2-microglobulin, and IGHV somatic hypermutational status. On the other hand, high MALAT1 expression was associated with several favorable prognostic markers (high hemoglobin, low serum lactate dehydrogenase, earlier clinical stages, CD38-negative status), but also with unfavorable cytogenetics. Furthermore, an association between high MALAT1 levels and longer time to first treatment and overall survival in IGHV-unmutated CLL subtype was observed. In summary, our results imply that high MALAT1 expression at diagnosis may be a predictor of better prognosis and point to MALAT1 expression profiling as a candidate biomarker potentially useful in clinical practice.

AB  - Global plastic waste accumulation has become omnipresent in public discourse and the focus of scientific research. Ranking as the sixth most produced polymer globally, polyurethanes (PU) significantly contribute to plastic waste and environmental pollution due to the toxicity of their building blocks, such as diisocyanates. In this study, the effects of PU on soil microbial communities over 18 months were monitored revealing that it had marginal effects on microbial diversity. However, Streptomyces sp. PU10, isolated from this PU-contaminated soil, proved exceptional in the degradation of a soluble polyester-PU (Impranil) across a range of temperatures with over 96% degradation of 10 g/L in 48 h. Proteins involved in PU degradation and metabolic changes occurring in this strain with Impranil as the sole carbon source were further investigated employing quantitative proteomics. The proposed degradation mechanism implicated the action of three enzymes: a polyester-degrading esterase, a urethane bond-degrading amidase and an oxidoreductase. Furthermore, proteome data revealed that PU degradation intermediates were incorporated into Streptomyces sp. PU10 metabolism via the fatty acid degradation pathway and subsequently channelled to polyketide biosynthesis. Most notably, the production of the tri-pyrrole undecylprodigiosin was confirmed paving the way for establishing PU upcycling strategies to bioactive metabolites using Streptomyces strains.

abstract = "Global plastic waste accumulation has become omnipresent in public discourse and the focus of scientific research. Ranking as the sixth most produced polymer globally, polyurethanes (PU) significantly contribute to plastic waste and environmental pollution due to the toxicity of their building blocks, such as diisocyanates. In this study, the effects of PU on soil microbial communities over 18 months were monitored revealing that it had marginal effects on microbial diversity. However, Streptomyces sp. PU10, isolated from this PU-contaminated soil, proved exceptional in the degradation of a soluble polyester-PU (Impranil) across a range of temperatures with over 96% degradation of 10 g/L in 48 h. Proteins involved in PU degradation and metabolic changes occurring in this strain with Impranil as the sole carbon source were further investigated employing quantitative proteomics. The proposed degradation mechanism implicated the action of three enzymes: a polyester-degrading esterase, a urethane bond-degrading amidase and an oxidoreductase. Furthermore, proteome data revealed that PU degradation intermediates were incorporated into Streptomyces sp. PU10 metabolism via the fatty acid degradation pathway and subsequently channelled to polyketide biosynthesis. Most notably, the production of the tri-pyrrole undecylprodigiosin was confirmed paving the way for establishing PU upcycling strategies to bioactive metabolites using Streptomyces strains.",

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  - Biofilm-associated infections are the main cause of biomaterial implant failure today. The increasing prevalence of antibiotic-resistant pathogens often results in the only solution of implant movement, with serious consequences for patients. Recently, various antimicrobial agents have been recognized as a promising strategy to prevent biofilm formation on implant surfaces. Quorum sensing (QS) plays a central role in the control of bacterial virulence and biofilm formation. The use of quorum quenching (QQ) enzymes to target QS is therefore a promising innovative approach for the development of enzyme-based antivirulence therapeutics, which represent a potential solution to combat infections caused by multidrug-resistant pathogens. This study aimed to characterize the novel YtnP lactonase from the clinical isolate Stenotrophomonas maltophilia 6960 and to investigate its potential to combat the virulence of multidrug-resistant (MDR) Pseudomonas aeruginosa MMA83.

AB  - Infections caused by multidrug-resistant pathogens are one of the biggest challenges facing the healthcare system today. Quorum quenching (QQ) enzymes have the potential to be used as innovative enzyme-based antivirulence therapeutics to combat infections caused by multidrug-resistant pathogens. The main objective of this research was to describe the novel YtnP lactonase derived from the clinical isolate Stenotrophomonas maltophilia and to investigate its antivirulence potential against multidrug-resistant Pseudomonas aeruginosa MMA83. YtnP lactonase, the QQ enzyme, belongs to the family of metallo-β-lactamases. The recombinant enzyme has several advantageous biotechnological properties, such as high thermostability, activity in a wide pH range, and no cytotoxic effect. High-performance liquid chromatography analysis revealed the activity of recombinant YtnP lactonase toward a wide range of N-acyl-homoserine lactones (AHLs), quorum sensing signaling molecules, with a higher preference for long-chain AHLs. Recombinant YtnP lactonase was shown to inhibit P. aeruginosa MMA83 biofilm formation, induce biofilm decomposition, and reduce extracellular virulence factors production. Moreover, the lifespan of MMA83-infected Caenorhabditis elegans was prolonged with YtnP lactonase treatment. YtnP lactonase showed synergistic inhibitory activity in combination with gentamicin and acted additively with meropenem against MMA83. The described properties make YtnP lactonase a promising therapeutic candidate for the development of next-generation antivirulence agents.

AB  - Ubiquitous post-consumer plastic waste is often physically mixed combining recalcitrant petroleum-based plastics with bioplastics, forming (petro-bio)plastic streams. Finding appropriate end-of-life (EoL) strategies for mixed (petro-bio)plastic waste is highly pertinent in achieving environmental protection, sustainability for plastic value chain industries including recyclers and government policy makers worldwide. The presence of bioplastic mixed in with polyethylene terephthalate (PET) or other petroleum-based plastic streams poses a substantial drawback to mechanical recycling and strongly impedes the development of sustainable EoL routes. Here, we present a model system for the sustainable management of mixed (petro-bio)plastic waste, demonstrating a biotechnological route through synergy-promoted enzymatic degradation of PET–representing petrochemical polyester plastic–mixed with thermoplastic starch (TPS)–as a model bioplastic. Leaf-branch compost cutinase (LCCICCG) and commercial amylase (AMY) deliver effective depolymerization of this mixed (petro-bio)plastic material, with subsequent bio-upcycling of the mixed waste stream into bacterial nanocellulose (BNC) by Komagataeibacter medellinensis. Compared to LCCICCG and AMY, the LCCICCG/AMY combined treatment synergistically produced a 2.6- and 4.4-fold increase in enzymatic decomposition at 70 °C in four days, respectively, yielding sugars and terephthalic acid (TPA) as the main depolymerization building blocks. Bio-upcycling of post-enzymatic degradation hydrolysates resulted in a high BNC yield of 3 g L−1 after 10 days. This work paves the way for sustainable management routes for challenging mixed recalcitrant plastic and bioplastic waste and prepares opportunities for its participation in the circular production of sustainable eco-polymers.

AB  - The objective of this study was to identify the requirements needed for selling dairy products through e-commerce, as well as current gaps and challenges that exist for small scale dairy processors (SSDPs), and need to be addressed in order to comply with those requirements. A mixed method research design was used for training needs assessment. Qualitative (in-depth interview with 7 online platform representatives (OPRs)) and quantitative approach (survey questionnaire with 58 SSDPs) were conducted. Interview transcripts were coded and codes were grouped into seven themes. Hierarchical cluster analysis was applied to 146 answers from 58 SSDPs. They were divided into 4 clusters. Mean sums of responses between clusters were compared by Mann-Whitney U test. OPRs suggested that SSDPs should be provided with tools and resources to help them achieve food safety and quality targets, as well as practical knowledge and skills. They reported that it is crucial to find a solution for the cold chain transportation, for maintaining consistent product quality. Survey results showed that SSDPs use kitchen equipment (79.3%) and kitchen cleaning products (81.0%) for dairy processing. In total, 43.1% process raw milk and only 24.1% have product label on the package. Only members of cluster 3 and 4 sell their products online (73.7% and 90.0%, respectively), mostly using their own social media platforms (57.9% and 60.0%, respectively), transporting products to end buyers by themselves in hand refrigerators (47.4% and 70.0%, respectively). By analyzing the differences among clusters of SSDPs, trainings can be tailored to the characteristics and knowledge gaps of each group.

In total, 43.1% process raw milk and only 24.1% have product label on the package. Only members of cluster 3 and 4 sell their products online (73.7% and 90.0%, respectively), mostly using their own social media platforms (57.9% and 60.0%, respectively), transporting products to end buyers by themselves in hand refrigerators (47.4% and 70.0%, respectively). By analyzing the differences among clusters of SSDPs, trainings can be tailored to the characteristics and knowledge gaps of each group.",
