Therapy of bacterial urinary tract infections (UTIs) and catheter associated urinary tract infections (CAUTIs) is still a great challenge because of the resistance of bacteria to nowadays used antibiotics and encrustation of catheters. Bacterial cellulose (BC) as a biocompatible material with a high porosity allows incorporation of different materi...
Bacterial infection and their resistance to known antibiotics delays wound healing. In this study, nanochitosan dots (nChiD) produced by gamma irradiation have been encapsulated in bacterial cellulose (BC) polymer matrix to study the antibacterial potentials of these nanocomposites and their possible usage in wound healing treatment (scratch assay)...
Since the pathogenic bacteria biofilms are involved in 70% of chronic infections and their resistance to antibiotics is increased, the research in this field requires new healing agents.
New composite hydrogels were designed as potential chronic wound dressings composed of bacterial cellulose (BC) with chitosan polymer (Chi) – BC-Chi and chitosan n...
Cellulose is a widespread macromolecule in terrestrial environments and a major architectural component of microbial biofilm. Therefore, cellulose might be considered a biosignature that indicates the presence of microbial life. We present, for the first time, characteristics of bacterial cellulose after long-term spaceflight and exposure to simule...
Due to their unique structural properties bacterial cellulose (BC) hydrogels find possible usage in many fields such as cosmetology, food industry, or medicine. In this study, photoactive BC hydrogels are investigated through modifications of their structural, mechanical, and pro-oxidant properties resulting from graphene quantum dots (GQDs) encaps...
Current environmental and energy concerns have led to lignin gaining increased attention in the last decade as a renewable biomass. Due to its structural and functional properties, such as antimicrobial behaviour, biodegradability, biocompatibility and ease of surface modifications, lignin-based materials have gained popularity in the biomedical fi...
Nowadays, it is a great challenge to develop new medicines for treating various infectious diseases. The treatment of these diseases is of utmost interest to further prevent the development of multi-drug resistance in different pathogens. Carbon quantum dots, as a new member of the carbon nanomaterials family, can potentially be used as a highly pr...
The large number of deaths induced by carcinoma and infections indicates that the need for new, better, targeted therapy is higher than ever. Apart from classical treatments and medication, photodynamic therapy (PDT) is one of the possible approaches to cure these clinical conditions. This strategy offers several advantages, such as lower toxicity,...
Carbon quantum dots (CQDs) are well known as a promising therapeutic agent due to their excellent pro-oxidant, antioxidant, antibacterial and anticancer properties under visible light irradiation. This material is easy to produce by several bottom-up or top-down methods. In this study, we used citric acid as starting precursor to synthesize aqueous...
Endowment "Veselin Lucic" of Belgrade University awarded our team for best paper on Belgrade University in field of natural sciences for year 2021.
Due to the increasing number of bacterial infections and the development of resistivity toward antibiotics, new materials and approaches for treatments must be urgently developed. The production of new materials should be ecologically friendly considering overall pollution with chemicals and economically acceptable and accessible to the wide popula...
The increased antibiotic resistance of pathogenic bacteria requires intense research of new wound healing agents. Novel wound dressings should be designed to provide wound disinfection, good moisture, and fast epithelization. In this study, bacterial cellulose (BC) was impregnated with graphene quantum dots (GQDs) for potential use in wound healing...
Regenerative medicine therapy is inspired by current research advances in cellular biology, genetic engineering, synthetic biology, material sciences and so far contributes to the traditional therapy, making resistant diseases curable. Nowadays, chronic wound healing is possible due to cell-based regenerative technologies and recent non-cell therap...
Lignins and lignin-derived compounds are known to have antibacterial properties. The wound healing agents in the form of dressings produce faster skin repair and decrease pain in patients. In order to create an efficient antimicrobial agent in the form of dressing in the treatment of chronic wounds, a composite hydrogel of bacterial cellulose (BC)...
Purpose: Extremely low frequency (ELF) magnetic fields as essential ecological factor may induce specific responses in genetically different lines. The subject of this study was to investigate the impact of ELF magnetic field on fitness components and locomotor activity of five Drosophila subobscura isofemale (IF) lines.
Materials and methods: Each...
Nowadays bacterial resistance to known antibiotics is a serious health problem. In order to achieve more efficient treatment, lately there is an effort to find new substances, such as certain biomaterials, that are non-toxic to humans with antibiotic potential. Lignins and lignin-derived compounds have been proposed to be good candidates for use in...
Spider silk poses excellent mechanical properties, tenacity and elasticity and it has been used as a template for calcite mineralization to improve load bearing strength of osteoconductive calcite. The samples were obtained by mimicking biomineralization for five days in order to follow formation and growth of calcite on the surface of spider silk....
Purpose:
Extremely low frequency (ELF) magnetic fields are essential ecological factors which may induce changes in many organisms. The aim of this study was to examine the effects in Drosophila subobscura exposed for 48 h to ELF magnetic field (50 Hz, 0.5 mT) at different developmental stages.
Materials and methods:
Egg-first instar larvae deve...
The effective population size (Ne) represents the number of individuals that can contribute genes
equal ly to the next generation and is usually smaller then the actual size of a population. The
aims of this study were: (i) to assess the Ne for two Drosophila subobscura populations sampled
from geographically close, but ecologically and topological...
The aim of this research was to examine the temporal patterns of spontaneous locomotor activity in Drosophila subobscura virgin females and males from isofemale lines collected from beech and oak forests and maintained in controlled laboratory conditions for five full-sib inbreeding generations. The flies were monitored in a circular open field are...
The genetic structure of Drosophila subobscura from the Balkan Peninsula was studied with respect to restriction site polymorphism of mitochondrial DNA in populations from the Derventa River Gorge and Sicevo Gorge (Serbia). To investigate the role of cytonuclear interactions in shaping mitochondrial DNA variability in natural populations of this sp...

Background: Some populations of Drosophila subobscura (Collin) inhabit geographically
separate and ecologically distinct habitats of the central Balkans.
Hypothesis: Some of the separate populations were genetically isolated in glacial refugia and
have subsequently diverged, leading to high genetic diversity.
Methods: We sampled five different D. s...
