2. Antibiotics and their different application strategies in controlling the biofilm forming pathogenic bacteriaFazlurrahman Khan, Dung T N Pham, Sandra Oloketuyi, Young-Mog Kim, 2020, pregledni znanstveni članek Opis: Background: The establishment of a biofilm by most pathogenic bacteria has been known as one of the resistance mechanisms against antibiotics. A biofilm is a structural component where the bacterial community adheres to the biotic or abiotic surfaces by the help of Extracellular Polymeric Substances (EPS) produced by bacterial cells. The biofilm matrix possesses the ability to resist several adverse environmental factors, including the effect of antibiotics. Therefore, the resistance of bacterial biofilm-forming cells could be increased up to 1000 times than the planktonic cells, hence requiring a significantly high concentration of antibiotics for treatment.
Methods: Up to the present, several methodologies employing antibiotics as an anti-biofilm, antivirulence or quorum quenching agent have been developed for biofilm inhibition and eradication of a pre-formed mature biofilm.
Results: Among the anti-biofilm strategies being tested, the sub-minimal inhibitory concentration of several antibiotics either alone or in combination has been shown to inhibit biofilm formation and down-regulate the production of virulence factors. The combinatorial strategies include (1) combination of multiple antibiotics, (2) combination of antibiotics with non-antibiotic agents and (3) loading of antibiotics onto a carrier.
Conclusion: The present review paper describes the role of several antibiotics as biofilm inhibitors and also the alternative strategies adopted for applications in eradicating and inhibiting the formation of biofilm by pathogenic bacteria.

3. Antimicrobial susceptibility profile of airborne bacteria and fungi at Owena Market, Osun State, NigeriaGbenga Folorunsho Oginni, Sandra Oloketuyi, Olufunke Chukwu, Janet Odunayo, 2017, izvirni znanstveni članek Opis: Environmental conditions and human activities influence the ubiquity and diversity of microorganisms in the atmosphere thereby acquiring the ability to resist antibiotics which poses serious public threat. Airborne bacteria and fungi isolated using settling plate method from three different points (where kolanuts, meat and onions are sold) at Owena Market, Osun state, Nigeria were assayed for antimicrobial susceptibility using disc diffusion. The microorganisms were identified as Staphylococcus aureus, Bacillus subtilis, Bacillus cereus, Proteus vulgaris, Bacillus megaterium, Alcaligenes spp., Aeromonas spp., Escherichia coli, Micrococcus spp., Streptococcus spp., Mortierella polycephala, Epicoccum nigrum, Alternaria spp., Penicillium chrysogenum, Aspergillus flavus, Acremonium spp., Penicillium oxalicum, Cladosporium cladosporiodes, Rhizopus stolonifer, Stemphylium spp., and Trichoderma spp. About 30% of the bacterial isolates were resistant to the antibacterial agents (antibiotics) and all the bacterial isolates were resistant to at least four or more antibiotics while 18% and 64% of the fungi isolated were susceptible to griseofulvin and ketoconazole, respectively. This study shows that the market environment serves as reservoirs for multiple antibiotic resistant bacteria and fungi capable of causing infectious diseases.

4. A comparative study of nanolaminate CrN/Mo2N and CrN/W2N as hard and corrosion resistant coatingsOrfeo Sbaizero, Marco Lazzarino, Gregor Kapun, Mattia Fanetti, Simone Dal Zilio, Andraž Mavrič, Marco Beltrami, Miha Čekada, 2013, izvirni znanstveni članek Opis: Nanolaminate coatings (NLC) consisting of alternated CrN coupled with either cubic tungsten nitride (β-W2N) or molybdenum nitride (γ-Mo2N) were deposited on cold worked tool steel substrates using reactive DC reactive magnetron sputtering for improved mechanical and corrosion resistance. The CrN/γ-Mo2N and CrN/β-W2N nanolaminate systems were found to perform better than the corresponding single-layer systems, with both mechanical and electrochemical properties improving by decreasing the individual layer thickness from 100 to 5 nm. The CrN/β-W2N NLC combined the high hardness value of W2N with the low corrosion current of CrN. The CrN/γ-Mo2N NLC showed synergistic improvements consisting of both higher hardness and lower corrosion currents with respect to the constituent materials alone. The dependence of mechanical and corrosion properties on the bilayer period is discussed in terms of the grain size, residual stresses and texture of the constituent materials and the nanostructured character of the multilayer architecture.

5. Human Sacrifice: The Scapegoat in Partisan Photographs at the End of the Italian Civil WarMartina Caruso, 2019, samostojni znanstveni sestavek ali poglavje v monografski publikaciji Opis: This essay examines how Partisan self-representation in photography directly participated in the creation of a post-war humanist visual culture embedded in an idea of Christian redemption.

7. Italian Humanist Photography from Fascism to the Cold WarMartina Caruso, znanstvena monografija Opis: Spanning four decades of radical political and social change in Italy, this interdisciplinary study explores photography’s relationship with Italian painting, film, literature, anthropological research and international photography. Evocative and powerful, Italian social documentary photography from the 1930s to the 1960s is a rich source of cultural history, reflecting a time of dramatic change. This book shows, through a wide range of images (some published for the first time) that to fully understand the photography of this period we must take a more expansive view than scholars have applied to date, considering issues of propaganda, aesthetics, religion, national identity and international influences. By setting Italian photography against a backdrop of social documentary and giving it a distinctive place in the global history of photography, this exciting volume of original research is of interest to art historians and scholars of Italian and visual culture studies.
