Twenty years after the war (1992-1995) in Bosnia and Herzegovina the country is still very fragile, dysfunctional and continues to face numerous political and socio-economic challenges. Ethnically fragmented and exclusivist approaches to education in Bosnia and Herzegovina are anathema to the development of critical thinking and analytical skills necessary to open young minds, reduce intolerance and question the ethnic status quo narrative (Perry, 2015). This paper will try to present a good example of academic and social successes achieved with students who are attending an English language teacher education program at the University of Sarajevo in the context of challenging teaching and learning environments. The paper will explore the possibilities and challenges for using a critical pedagogy framework and intercultural approach to foreign language education in pre-service teacher education courses that emphasizes reflection, critical thinking, empathy, multiperspectivity along with other aspects of intercultural communicative competences which are integrated in this course.

Fifteen Brassica oleracea L. var. acephala DC accessions were collected and evaluated for their genetic diversity and molecular characteristics using 10 previously developed and used codominant SSR markers. The SSR loci used revealed a total of 51 alleles. The domestic kale varieties were collected locally and the hybrids kales were found in markets. The averages of total heterozygosity (H) and polymorphic information content (PIC) was 0.6774 and 0.6201, respectively. The average number of alleles was 4.2 per locus, where 8 of 10 markers showed high polymorphic information content (PIC), being more than 0.5. The genetic relationships among the populations revealed by Unweighted Pair Group Method with Arithmetic mean (UPGMA), showed a clear clustering into three distinct groups. As expected, all local varieties were separated within two separated clusters, whereas only two domestic varieties shared one cluster with the group of hybrids, indicating similar genetic background shared by domestic and hybrid varieties. These results indicate and confirm the regional and physiological differences between the kale varieties and confirm the SSR marker efficiency for genetic characterization assays.

 merima.ibisevic@untz.ba ABSTRACT: Origanum compactum (Lamiaceae) is an endemic species of oregano from Morocco, and the main components are carvacol and thymol, which are considered to have antimicrobial activity. Essential oils can be unstable, poorly soluble in water and poorly delivered to target cells. The incorporation of essential oils into liposomes can reduce their irritant effect, while at the same time prolonging the action of the preparation itself as well as increasing its effectiveness. The aim of our study was to investigate antimicrobial activity of liposomal and non-liposomal vaginal suppositories, and see if there are any differences in antimicrobial activity. Examination of the antimicrobial activity of vaginal suppositories was examined in the same way as the antimicrobial activity of the essential oil, by the disk diffusion method. There were used standard bacterial strains from ATCC collection: Staphylococcus aureus ( S. aureus ) ATCC 25923, Enterococcus faecalis ( E. faecalis ) ATCC 51299, Escherichia coli ( E. coli ) ATCC 25922, Candida albicans ( C. albicans ) ATCC 10231. Liposomal vaginal suppositories had a smaller inhibition zones probably due to the slower release of active components, but still have an advantage over non-liposomal vaginal suppositories because they reduce the irritating potential of the

Telekia speciosa (Schreb.) Baumg., Asteraceae, is widespread in Eastern and Central Europe and the Balkan Peninsula. Previous phytochemical investigations have revealed T. speciosa as a rich source of sesquiterpene lactone -isoalantolactone, especially in its underground parts. The aim of the present study was to analyze the essential oils from aerial and underground parts of T. speciosa and investigate their antimicrobial activity. Chemical composition of essential oils was determined by GC-FID/MS method leading to the identification of 67 compounds in total, with 15.77 % oxygenated monoterpenes, 7.77 % sesquiterpene hydrocarbons, 49.14 % oxygenated sesquiterpenes, and 12.37 % other compounds from aerial parts, and 3.80 % oxygenated monoterpenes, 3.13 % sesquiterpene hydrocarbons, 90.33 % oxygenated sesquiterpenes from underground parts essential oil. The main components from aerial parts were (E)-nerolidol (11.54 %) and caryophyllene oxide (10.54 %), while isoalantolactone was the predominant component from essential oil underground parts (83.41 %). The minimum inhibitory concentration (MIC), minimum bactericidal/fungicidal concentration of the essential oils were evaluated against six strains of bacteria and two strains of fungus using in vitro microdilution method. Both oils presented antimicrobial properties against pathogens Staphylococcus aureus, Bacilus cereus, Pseudomonas aeruginosa, Escherichia coli, and Candida albicans. Inhibition of growth of tested microorganisms by T. speciosa underground parts essential oil was achieved with MICs ranging from 1.0 to 11.0 mg mL -1 , while MICs of aerial parts essential oil varied from 4.0 to 30.0 mg mL -1 . The obtained results contribute to the knowledge of antimicrobial properties of T. speciosa, which support traditional uses underground parts of the plant.

: The chemistry of complex compounds containing imine ligands is attracting significant attention from research-ers today. In this work, complexes of selected transition metals (Cu, Co, Ni and Fe) with imines based on ninhydrin and amino acids methionine and cysteine were synthesized. FTIR and UV/VIS spectroscopy were used for structural characterization. Antioxidant activity of the complex was analyzed by the FRAP method. The synthesized compounds showed a significant reducing ability, ranging from 221.94 to 756.30 µmol/L. In vitro antimicrobial activity was tested on strains from the ATCC collection. Inhibitory activity against the tested microorganisms was recorded, and the zones of inhibition ranged from 10-24 mm. Preliminary research shows that these compounds have biological potency, but more detailed in vitro and in vivo studies are required for their use.
