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  - Antimicrobial resistance (AMR) has developed as
one of the top 10 global public health threats
facing humanity. As the nosocomial bacterial
strains are being increasingly resistant to most
clinically available antibiotics, there is a constant
need for exploration of new substances
that could kill them or inhibit their growth, or
alternatively inhibit some of their essential virulence
factors to counteract the lack of new antibacterials
and the rise of antibiotic resistance,
plants could represent a potential solution.
Plants produce a variety of bioactive secondary
metabolites that could be used to fuel the future
discovery pipeline. Aim of the present study was
to examine inhibitory activity of the supercritical
extract of J. communis L. green pseudofructus
(7SCO2) against the growth, biofilm production
and several virulence factors of significant nosocomial
bacterial pathogens. The extract was
obtained by fractional extraction with supercritical
CO2, and the qualitative and quantitative
analysis was performed using the GC-FID/MS
method. Clinical isolates of Pseudomonas aeruginosa,Acinetobacter baumannii, Staphylococcus
aureus (methicillin-sensitive-MSSA and methicillin-
resistant - MRSA), Enterococcus faecalis, and
Klebsiella pneumoniae, as well as their antibiotic
resistance profiles, were obtained from the Clinical
Hospital Centre “Dr Dragiša Mišović Dedinje”.
Minimum inhibitory concentrations (MICs) of
the 7SCO2 were determined by broth-microdilution
method. Examination of the anti-adhesive
effect of the extract was carried out using the
spectrophotometric method. The pyocyanin
production of Pseudomonas aeruginosa was determined
by the method described by Rampioni
et al. Most significant findings of this study
are potent antivirulence activity of the 7SCO2
against P. aeruginosa through the inhibition of
pyocyanin production. In addition, the biofilm
production of A. baumannii was inhibited by the
7SCO2 in concentration 50 μg/mL. Finally, notable
antivirulence activity of the 7SCO2 against
E. faecalis and S. aureus was detected, since it
significantly inhibited collagen and laminin adhesion
of these pathogens.

AB  - Alterations in gut microbiota and deregulation
of the gut immune system are recognized
as important events in autoimmune diseases.
The knowledge about the important role of anaerobic
gut bacteria that produce short-chain
fatty acids (SCFAs), in the regulation of intestinal
barrier and immune response made a way
for the development of microbiota-based interventions.
Our research aimed to isolate the
strains with the potential to produce SCFAs,
from healthy volunteer fecal material, and to
test their effects on IL-8 production in the culture
of intestinal epithelial cells (Caco2) as an in
vitro system imitating initial intestinal inflammation,
the effects on the expression of neuronal
activity-regulated genes of Caenorhabditis
elegans, and the effect on the development
of experimental autoimmune encephalomyelitis
(EAE), a mouse model of multiple  sclerosis.
Three isolated butyric acid (BA)-producing
strains, and three acetic acid (AA)-producing
strains diminished the production of IL-8 in Caco-
2 cells treated with IL-1β/TNF-α. Further, all
BA-producing strains stimulated the expression
of important neuro-related genes in C. elegans.
Based on the strongest effects in these
assays an isolate identified as Faecalimonas sp.
NGB245 strain was further tested in EAE model.
The oral treatment of EAE-induced mice with
this strain for 16h per day for 15 days resulted
in alleviated daily clinical scores, maximal
clinical scores, and the duration of the illness
in comparison to the effect of media used for
strain cultivation. These results point to the potential
of NGB245 to modify the gut-brain axis
opening the field for future development of microbiota-
based therapy for the diseases associated
with immune response dysfunctions.

AB  - Skin microbiome emerged as an important
factor which can balance tissue repair process
and wound healing. Recent evidence suggest
that intracellular bacterial localization could be
associated with the aberrant healing observed
in patients with chronic wounds, while therapeutics
targeting intracellular bacteria remain
limited. Probiotic lactobacilli and their bioactive
lysates (postbiotics) are well known for their role
in maintenance of gut epithelial homeostasis.
Hence, in this study we focused to understand
the mechanisms of cutaneous response to fourteen
postbiotics derived from different lactobacilli
to reduce intracellular Staphylococcus aureus
colonization and promote healing. Latilactobacillus
curvatus BGMK2-41 demonstrated the
most efficient capability to reduce intracellular infection by S. aureus in keratinocytes in vitro and
infection of human skin explants. Reduction of
bacterial number was followed by upregulation
of the expression of antimicrobial response
genes. Furthermore, BGMK2-41 postbiotic treatment
stimulates keratinocyte migration in vitro
and increases expression of anti-inflammatory
cytokine IL-10, promotes wound closure and
strengthens the epidermal barrier via upregulation
of tight junction proteins in a human ex vivo
wound model. Altogether, this study provided
evidence that postbiotics could stimulate fortification
of epithelial barrier to suppress dissemination
of intracellular pathogens which can be
used as a novel approach to treat dermatologic
and wound healing disorders associated with
persistent infections.

31294207). One interesting class of compounds
responsible for the aggregation of lactic
acid bacteria is aggregation factors—surface
high-molecular-weight proteins rich in threonine
and lysine (PMID: 30027759). Recently,
our research group discovered a new strain of
Streptococcus thermophilus in the mountainous
regions of Serbia, exhibiting an aggregation
phenotype. Aggregation phenotype was confirmed
visually and using microscopy. Complete
genome of Agg+ strain was sequenced using
NGS and a gene encoding a potential aggregation
factor, which was named aggS was identified.
The predicted threonine (12.5%) and lysine
(10.5%) rich protein contains 2367 amino acids,
with an average molecular weight of 255986.63
Da. AggS also contains two cysteine residues,whereas previously well-described aggregation
factors of this type did not contain any cysteine
residues. The predicted protein includes an
N-terminal YSIRK-like signal sequence and an
LPXTG cell wall anchor domain. It has 6 Mucin
binding domain repeats alternating with 6 Mub
B2-like domain repeats. Additionally, we found a
region resembling an ice-binding domain. Given
that these bacteria endure prolonged periods of
low temperatures, it can be speculated that this
surface membrane protein also helps the bacteria
withstand freezing. The fact that the alignment
using BLASTp revealed AggS to be most
closely related to an uncharacterised protein
from the genome of Lactococcus garvieae, along
with the discovery of a transposase gene sequence
upstream of the gene, suggests that the
aggregation factor was likely acquired through
horizontal gene transfer. We plan to clone it into
a shuttle vector and investigate the aggregation
phenotype using a heterologous expression system
in Lactococcus lactis, as well as explore its
other functions.

25 NGPs with confirmed safe status and potential
probiotic potential were screened in C. elegans

with ability to upregulate expression of genes
involved in neurotransmiting are further tested
in EAE (an animal model for MS) and CUMS depression

AB  - The increasing production and utilization of
synthetic polymers in the textile industry over
the past five decades has raised concerns about
the environmental impact of the industry. The
recalcitrant nature of synthetic fibers hampers
the biodegradation of these textiles in the environment
and leads to the accumulation of textile
waste. Effective solutions for recycling and proper
disposal of textile waste are lacking, however,
the use of microorganisms and enzymes has
emerged as a promising approach. The genus
Streptomyces has been well studied as a producer
of different hydrolytic enzymes, several of which
have found use in industrial settings as well. As
an integral part of the soil microbiome, Streptomyces
species have been shown to interact with
different textile materials in soil and may play a
role in the degradation of these materials. This
study aimed to examine the interaction of Streptomyces
sp. R1, isolated from the rhizosphere of
Cotinus coggygria, with polyamide/polyurethane
textile, and identify potential enzymes involved in the biodegradation of synthetic textiles. The
degradation of the textile was tested in liquid
cultures (minimal salt medium) and model compost,
bio-augmented with Streptomyces sp. R1
for 4 months. After the incubation, morphological,
and changes in the functional groups of the
textiles were analysed using scanning electron
microscopy (SEM) and Fourier transform infrared
spectroscopy (FTIR). The surface of the textile
showed noticeable cracks and fissures after
4 months of burial in the bioaugmented model
compost, alongside changes in the functional
groups of the polyamide/polyurethane textile,
which indicates biodegradation of the synthetic
fibers. Searching the genome of Streptomyces sp.
R1, several enzymes involved in the degradation
of synthetic polymers were identified, including
an esterase homologous to highly efficient plastic
degrading depolymerases. Overall, the results
presented here indicate Streptomyces sp. R1 has
the potential for synthetic textile degradation
and bioremediation.

AB  - The rapid emergence and spread of multidrug-

healthcare challenge. One common cause of
resistance and/or tolerance to antibiotics is
biofilms, a complex communities of bacteria
embedded in a self-produced matrix. Biofilm
formation and maturation are regulated by
quorum sensing, a cell density-dependent communication
system that relies on the synthesis,
diffusion, and detection of small signaling molecules
- autoinducers (AIs). Quorum quenching
(QQ) enzymes that cut Ais emerged as a promising
strategy for persistent bacterial infections.
However, a significant drawback for the use of
QQ enzymes as therapeutics is their poor stability
and efficacy in vivo. Since one of the major
health issues linked to biofilm development is
persistent wound infections, our goal was to
improve enzyme properties by immobilizing it
on a natural biopolymer to make it suitable for
use as a wound dressing. The best candidate for immobilization was YtnP lactonase from Bacillus
paralicheniformis ZP1, as in concentrations
higher than 25 μg/mL it improved the survival of
Pseudomonas aeruginosa PAO1-infected zebrafish,
rescuing 80% of embryos. When combined
with tobramycin or gentamicin, the survival
rate of zebrafish embryos increased to 100%.
Purified YtnP lactonase at a concentration of 1
mg was immobilized on 10 mg of polymer disks
by crosslinking with glutaraldehyde. Specific
modifications of the polymer were also made to
eliminate the use of glutaraldehyde, which is a
skin irritant. In in vivo experiments on a murine
chronic wound model, immobilized enzyme
inhibited biofilm development, cleared already
formed biofilms, and overall improved wound
healing. These results provide a foundation for
the development of advanced wound dressings
that will prevent infection development in
wounds and enable proper therapy for infected

AB  - The formation of biofilms by foodborne pathogens
is a constant challenge in the food industry,
leading to an increased risk of contamination and
compromising food safety. Many of the chemicals
commonly used for sanitation in the food industry
are unable to remove biofilms, are harmful
to surfaces and can be toxic. The effectiveness
of disinfectants can be improved using enzymes
that specifically target biofilm components such
as exopolysaccharides, extracellular DNA, or proteins.
In this study we investigated the potential
of glycoside hydrolases originating from the
gill microbiota of freshwater fish to control biofilm
formation in the most common foodborne
pathogens. We demonstrated that β-glucosidase
from Microbacterium sp. BG28 (BglB-BG28) effectively
inhibits cellulose-rich biofilms formed by
Salmonella enteritidis, S. typhimurium, S. infantis,
and Escherichia coli. When these bacteria were cultivated overnight with 200 μL/mL enzyme, up
to 80% less biofilm was formed. By fluorescence
microscopy, we visualised the inhibition of biofilms
on plastic, glass and aluminium, materials
commonly used in the food industry. When used
as a pre-treatment, BglB-BG28 increased the
bactericidal efficacy of Oxicid®S, a commercially
available surface disinfectant. Its effectiveness at
temperatures up to 50 °C and in a pH range from
4 to 8 together with compatibility with non-ionic
detergents and high tolerance to sodium chloride
and glucose give BglB-BG28 advantages in
harsh and diverse industrial environments. Importantly,
no toxicity to Caenorhabditis elegans
was observed at enzyme concentrations of up
to 1 mg/ml. Overall, these results demonstrate
the suitability of the β-glucosidase BglB-BG28 for
the formulation of a novel enzyme-based disinfectant
to be used in food processing facilities.

on plastic, glass and aluminium, materials
commonly used in the food industry. When used
as a pre-treatment, BglB-BG28 increased the
bactericidal efficacy of Oxicid®S, a commercially
available surface disinfectant. Its effectiveness at
temperatures up to 50 °C and in a pH range from
4 to 8 together with compatibility with non-ionic
detergents and high tolerance to sodium chloride
and glucose give BglB-BG28 advantages in
harsh and diverse industrial environments. Importantly,
no toxicity to Caenorhabditis elegans
was observed at enzyme concentrations of up
to 1 mg/ml. Overall, these results demonstrate
the suitability of the β-glucosidase BglB-BG28 for
the formulation of a novel enzyme-based disinfectant
to be used in food processing facilities.",

AB  - Acinetobacter baumannii is considered one of
the greatest threats to public health on a global
scale. This Gram-negative pathogen causes
severe infections, mostly of nosocomial origin,
with a high mortality rate. In recent years, the
rapid increase in the emergence and spread of
antibiotic resistance in A. baumannii has significantly
limited the effective therapeutic options
against infections caused by this bacterium.
The last-line antibiotics used in the treatment
of multidrug-resistant (MDR) A. baumannii
are carbapenems, tigecycline and polymyxins.
However, resistance to these antibiotics is
steadily increasing, especially to carbapenems,
leading to an extensively drug-resistant (XDR)
and even pandrug-resistant (PDR) phenotype
of A. baumannii. In 2021, the European Centre
for Disease Prevention and Control (ECDC) reported
that resistance of Acinetobacter spp. to
carbapenems reached 50% or more, mostly in
Southern and Eastern European countries. Although
the Western Balkans is a part of this region,
detailed studies on the epidemiology and
antibiotic resistance of A. baumannii are mainly
limited to Serbia and Croatia. In most cases, carbapenem
resistance in A. baumannii is due to
the production of carbapenemases, in particular
b-lactamases belonging to the class D known
as oxacillinases. The studies from the Western
Balkan countries revealed that besides the intrinsic
blaOXA-51-like gene, the most prevalent
acquired oxacillinase gene was the blaOXA-
24-like followed by the blaOXA-23-like, while
the blaOXA-58-like and metallo- b-lactamase
blaNDM-1 genes were less common. Although
significantly lower compared to carbapenem-resistant,
the number of A. baumannii isolates resistant
to tigecycline and colistin is on a continual
rise in the Western Balkans. As worldwide,
the main mechanism conferring tigecycline resistance
to A. baumannii from the Western Balkans
was overexpression of efflux pumps. Also,
the majority of reported alternations leading to
colistin resistance in A. baumannii were found in
the pmrCAB operon, which is responsible for the
modification of the colistin target, LPS.

AB  - Fungal infections, once considered a rare disease,
have become an everyday problem in modern
societies, posing major challenges to global
health. It is estimated that more than one billion
people are affected by fungal infections and 1.6
million people succumb to these diseases every
year. Of the 600 species of fungi capable of causing
infections in humans, species of the genus
Candida cause more than 85% of infections, especially
C. albicans, which has become a serious
threat to human health in immunocompromised
and immunosuppressed individuals. Unfortunately,
the current arsenal of clinical drugs relies
on only four classes of approved drugs (polyenes,
azoles, echinocandins and allylamines), which
are only partially effective, resulting in incomplete
eradication of the fungal infection. In
addition, the serious side effects, ranging from
systemic or organ-specific toxicity to poor bioavailability
and low activity, significantly hamper
the clinical use of antifungals. These problems
call for new effective and safe antifungal agents,but also for appropriate preclinical models to accurately
study potential adverse effects on the
human population and test their efficacy against
fungal infections. In this sense, zebrafish (Danio
rerio) embryos have become one of the most
powerful preclinical animal models in infection
biology and drug discovery, offering the unique
opportunity to simultaneously monitor the safety
and efficacy of the applied molecule in real
time. With the aim of providing a preclinical platform
for the identification of new safe antifungal
drugs to effectively control C. albicans infection,
we comprehensively tested the toxicity of 13
clinical antifungal drugs in the zebrafish embryo
model. The 21 toxicity endpoints, including
survival, teratogenicity, cardiotoxicity and hepatotoxicity,
were evaluated and compared with
adverse effects described in rats and humans. Of
the clinical drugs, the efficacy of fluconazole and
voriconazole was evaluated in the zebrafish - C.
albicans model of systemic and wound biofilm
infection.

AB  - Osteosarcoma (OS) is a highly aggressive primary malignant bone tumor that most commonly affects children, adolescents, and young adults. The standard treatment for OS consists of surgical resection and chemotherapy, whereas radiation therapy is recommended for the unresectable tumor. Due to its easy metastasis and recurrence, the 5-year overall survival rate is only 66.5 %. Thus, there is a critical need to recognize the molecular mechanisms underlying OS development and pathogenesis. Traditionally, two-dimensional (2D) cells are widely used in cancer biology and pre-clinical studies. However, 2D models are unable to mimic cell–cell and cell-extracellular matrix interactions which are crucial for adequate cellular function. Three-dimensional (3D) model systems are able to recapitulate key features of human cancer and are recognized as a promising platform for fundamental and translational research. In the present work, we established an osteosarcoma 3D model based on alginate microbeads and studied the effect of combined treatment with doxorubicin (Doxo), widely used chemotherapeutic, and quercetin (Quer), a plant pigment with anticancer properties, on OS model systems.

AB  - Development of novel, effective, and safe anti-tumor drugs is still a slow and cumbersome process, which is often attributed to weaknesses of current preclinical assays and low correlation of the preclinical in vitro and in vivo data with the results obtained in clinical trials. Consequently, there is a clear need for development of more reliable in vitro three dimensional (3D) tumor models, which will capture key features of the in vivo tumor cell microenvironment and provide drug testing results relevant for human patients. The aim of the project “Biomimetic tumor engineering to enhance drug discovery – BioengineeredTumor” funded by the Science Fund of the Republic of Serbia is to develop 2 novel, simple and robust 3D models for cultures of carcinoma and osteosarcoma cells by applying systematic and integrated methodology to comprehensively define the key model components. In specific, the aim is to use different human and animal cancer cell lines in conjunction with alginate-based biomaterials as artificial extracellular matrices imitating tumor environments and to cultivate the obtained constructs in perfusion bioreactors providing enhanced transport of nutrients, gases and biochemical signals to the cells as well as adequate levels of hydrodynamic shear stresses. Thus, the strategic goal is to establish an adaptable platform suited to the use by scientists without technical expertise for long-term in vitro studies of cancer cells for applications in anti-cancer drug discovery and validation, development of personalized medical treatments, and cancer research.

AB  - Pseudomonas aeruginosa is a Gram-negative
pathogen responsible for frequent hospital-acquired
infections of the bloodstream, the respiratory
tract, and the urinary tract. Quorum
quenching enzymes are recognized as an alternative
antivirulence approach targeting pathogenic
bacteria. The efficacy of YtnP lactonase in
reducing the virulence of P. aeruginosa MMA83
in vivo using Caenorhabditis elegans as a model
system was investigated. The recombinant YtnP
lactonase exhibits no cytotoxicity, demonstrated
by its lack of harmful effects on both the
immortalized human HaCaT cell line and two
strains of C. elegans (AU37 and N2 wild-type). In
a toxin-mediated killing liquid assay, the survival
rates of C. elegans AU37 mutant and N2 wildtype
strains infected with the clinical isolate P.
aeruginosa MMA83 significantly increased when
pre-treated with YtnP lactonase, compared to
untreated controls. Considering that virulence
factors expression is regulated by quorum sensing
(QS) signaling it is hypothesized that YtnP
lactonase prolongs the life span of C. elegans
by downregulating the QS and expression of
virulence factors of MMA83. The protective effects
of YtnP lactonase against MMA83-induced
pathogenicity in C. elegans, coupled with its absence
of cytotoxicity, position YtnP lactonase as
a promising prophylactic agent with antivirulence
properties.

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  - Recognizing that metal ions play an important role in modifying the pharmacological properties of known organic-based drugs, the present manuscript addresses the complexation of the antifungal agent voriconazole (vcz) with the biologically relevant silver(I) ion as a strategy for the development of new antimycotics. The synthesized silver(I) complexes with vcz were characterized by mass spectrometry, IR, UV–Vis and NMR spectroscopy and single-crystal X-ray diffraction analysis. The crystallographic results showed that complexes {[Ag(vcz)(H2O)]CH3SO3}n (1), {[Ag(vcz)2]BF4}n (2) and {[Ag(vcz)2]PF6}n (3) have polymeric structures in the solid state, in which silver(I) ions have a distorted tetrahedral geometry. On the other hand, DFT calculations revealed that the investigated silver(I) complexes 1–3 in DMSO exist as linear [Ag(vcz-N2)(vcz-N19)]+ (1a), [Ag(vcz-N2)(vcz-N4)]+ (2a) and [Ag(vcz-N4)2]+ (3a) species, respectively. The evaluated complexes showed an enhanced anti-Candida activity compared to the parent drug with minimal inhibitory concentration (MIC) values in the range of 0.02–1.05 μM. In comparison with vcz, the corresponding silver(I) complexes showed better activity in prevention hyphae and biofilm formation of C. albicans, indicating that they could be considered as promising agents against Candida that significantly inhibit its virulence. Also, these complexes are much better inhibitors of ergosterol synthesis in the cell membrane of C. albicans at the concentration of 0.5 × MIC. This is also confirmed by a molecular docking, which revealed that complexes 1a – 3a showed better inhibitory activity than vcz against the sterol 14α-demethylase enzyme cytochrome P450 (CYP51B), which plays a crucial role in the formation of ergosterol.

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  - 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.

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  - 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.

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  - 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.

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.
