With the growing issues of food spoilage, microbial resistance, and high mortality caused by cancer, the aim of this study was to evaluate T. zygis essential oil (TZEO) as a potential solution for these challenges. Here, we first performed GC/MS analysis which showed that the tested TZEO belongs to the linalool chemotype since the abundance of linalool was found to be 38.0%. Antioxidant activity assays showed the superiority of TZEO in neutralizing the ABTS radical cation compared to the DPPH radical. The TZEO was able to neutralize 50% of ABTS•+ at the concentration of 53.03 ± 1.34 μg/mL. Antimicrobial assessment performed by employing disc diffusion and minimal inhibitory concentration assays revealed TZEO as a potent antimicrobial agent with the highest inhibition activity towards tested gram-negative strains. The most sensitive on the treatment with TZEO was Enterobacter aerogenes showing an MIC 50 value of 0.147 ± 0.006 mg/mL and a MIC 90 value of 0.158 ± 0.024 mg/mL. Additionally, an in situ analysis showed great effects of TZEO in inhibiting gram-negative E. coli, P. putida, and E. aerogenes growing on bananas and cucumbers. Treatment with the TZEO vapor phase in the concentration of 500 μg/mL was able to reduce the growth of these bacteria on the food models to the extent > 90%, except for E. coli growth on the cucumber, which was reduced to the extent of 83.87 ± 4.76%. Furthermore, a test on the antibiofilm activity of the tested essential oil revealed its biofilm prevention effects against Salmonella enterica which forms biofilms on plastic and stainless-steel surfaces. Performed tests on the TZEO effects towards cell viability showed no effects on the normal MRC-5 cell line. However, the results of MTT assay of TZEO effects on three cancer cell lines (MDA-MB-231, HCT-116, and K562) suggest that TZEO exerted the strongest effects on the inhibition of the viability of MDA-MB-231 cells, especially after long-term treatment in the highest concentration applied with reducing the viability of the cells to 57%. Additionally, results of NBT and Griess assays suggest that TZEO could be a convenient candidate for future testing for developing novel antitumor therapies.

Introduction/purpose: This paper presents the transformation of the current, classical approach to teaching. Online platforms enable students with and without disabilities to follow classes without hindrance during the lecture period. After the lecture, they are allowed to view video and presentation materials. The main advantage of this way of teaching is the possibility of attending classes from any location and from any device; it is only important to be connected to the Internet. Methods: Full integration with the already existing Faculty Information System has been performed. The paper describes a new approach to teaching and illustrates the expected benefits of online teaching. The platforms used in this integration are Microsoft Azure, Microsoft Office 365 Admin, Microsoft Teams, Microsoft Stream and Microsoft SharePoint. Results: The result of the test of work with students showed that by introducing a system for online teaching, we directly affect the improvement and quality of teaching. Conclusion: Considering all the results, it can be concluded that the transition to the online way of teaching allows end listeners a comprehensive transfer of knowledge as well as re-listening to the same. This model can be used for an unlimited number of users in all Institutions, regardless of whether the field of activity of these Institutions is of educational origin.

Objectives: The goal of this study was to examine the antioxidant activity of Viscum album L. (VA, European mistletoe) extract (VAE) and to investigate whether VAE could provide protection against chlorpyrifos-induced hepatotoxicity. Methods: Male Wistar albino rats were divided into five groups and treated two times per week during four weeks: I group without treatment served as control; II, IV and V group were treated with chlorpyrifos (CPF, 35 mg/kg b.w) via gavage; III and IV group received a higher dose of VAE (350 mg/kg b.w); and V group received a lower dose of VAE (175 mg/kg b.w) intraperitoneally. The extract was obtained by ultrasound-assisted extraction. HPLC-DAD analysis was performed to investigate the chemical composition of the extract, and antioxidant assays to determine its antioxidant activities. Biochemical parameters, antioxidant enzyme activities in liver tissue, and histopathology were also determined. Results: The VAE caused significant decrease in glucose, TC, TG, albumins, AST, and ALT compared to CPF-treated rats. The cotreatment with VAE also significantly recovered the antioxidative system parameters (SOD, CAT, GSH-Px, GR, and GST) and alleviated some histopathological changes caused by CPF. Conclusions: Our data revealed that the simultaneous VAE administration modulated the negative changes induced by CPF. This study suggests that VAE could be useful in providing protection against hepatotoxicity and oxidative stress due to its antioxidative properties.

The aim of this study was to evaluate the antioxidant, antibiofilm, antimicrobial (in situ and in vitro), insecticidal, and antiproliferative activity of Cupressus sempervirens essential oil (CSEO) obtained from the plant leaf. The identification of the constituents contained in CSEO was also intended by using GC and GC/MS analysis. The chemical composition revealed that this sample was dominated by monoterpene hydrocarbons α-pinene, and δ-3-carene. Free radical scavenging ability, performed by using DPPH and ABTS assays, was evaluated as strong. Higher antibacterial efficacy was demonstrated for the agar diffusion method compared to the disk diffusion method. The antifungal activity of CSEO was moderate. When the minimum inhibitory concentrations of filamentous microscopic fungi were determined, we observed the efficacy depending on the concentration used, except for B. cinerea where the efficacy of lower concentration was more pronounced. The vapor phase effect was more pronounced at lower concentrations in most cases. Antibiofilm effect against Salmonella enterica was demonstrated. The relatively strong insecticidal activity was demonstrated with an LC50 value of 21.07% and an LC90 value of 78.21%, making CSEO potentially adequate in the control of agricultural insect pests. Results of cell viability testing showed no effects on the normal MRC-5 cell line, and antiproliferative effects towards MDA-MB-231, HCT-116, JEG-3, and K562 cells, whereas K562 cells were the most sensitive. Based on our results, CSEO could be a suitable alternative against different types of microorganisms as well as suitable for the control of biofilms. Due to its insecticidal properties, it could be used in the control of agricultural insect pests.

The use of medicinal herbs can mitigate oxidative stress-induced diabetic complications and organ failure. This study investigated hepato- and reno-protective effects of methanol extract of Centaurium erythraea Rafn (CEE) in STZ-diabetic rats pre-treated (2 weeks) and/or post-treated (4 weeks) with CEE (orally, 100 mg/kg/day). Both CEE treatments markedly improved liver and kidney functionality in diabetic rats observed as reduced aspartate and alanine aminotransferase activities and decreased creatinine and blood urea nitrogen levels. CEE pre-treatment reduced the level of glycosylated proteins in diabetic liver more efficiently than post-treatment. Lowered levels of lipid peroxidation, DNA damage and protein glutathionylation, elevated ratio of reduced to oxidized glutathione, and mitigated disturbance of antioxidant enzyme activities reflected the antioxidant effect of CEE in diabetic liver and kidney. Although CEE pre-treatment was more effective, the obtained results indicate that both treatments protect the liver and kidney from oxidative damage by boosting the endogenous antioxidant defense system.

Scaffolding biomaterials are gaining great importance due to their beneficial properties for medical purposes. Targeted biomaterial engineering strategies through the synergy of different material types can be applied to design hybrid scaffolding biomaterials with advantageous properties for biomedical applications. In our research, a novel combination of the bioactive agent Manuka honey (MHo) with 2-hydroxyethyl methacrylate/gelatin (HG) hydrogel scaffolds was created as an efficient bioactive platform for biomedical applications. The effects of Manuka honey content on structural characteristics, porosity, swelling performance, in vitro degradation, and in vitro biocompatibility (fibroblast and keratinocyte cell lines) of hybrid hydrogel scaffolds were studied using Fourier transform infrared spectroscopy, the gravimetric method, and in vitro MTT biocompatibility assays. The engineered hybrid hydrogel scaffolds show advantageous properties, including porosity in the range of 71.25% to 90.09%, specific pH- and temperature-dependent swelling performance, and convenient absorption capacity. In vitro degradation studies showed scaffold degradability ranging from 6.27% to 27.18% for four weeks. In vitro biocompatibility assays on healthy human fibroblast (MRC5 cells) and keratinocyte (HaCaT cells) cell lines by MTT tests showed that cell viability depends on the Manuka honey content loaded in the HG hydrogel scaffolds. A sample containing the highest Manuka honey content (30%) exhibited the best biocompatible properties. The obtained results reveal that the synergy of the bioactive agent, Manuka honey, with 2-hydroxyethyl methacrylate/gelatin as hybrid hydrogel scaffolds has potential for biomedical purposes. By tuning the Manuka honey content in HG hydrogel scaffolds advantageous properties of hybrid scaffolds can be achieved for biomedical applications.

Relations among Jews and Gentiles in Kosovo and Metohija between the Two World Wars: From Autocentrism to Assimilation The period between the two world wars in Kosovo and Metohija (1918-1941) was a peak period of legal protection, economic development, national and political self-positioning, educational and cultural emancipation, and general progress of the local Jewish community. The local Sephardic community, dedicated to tradition, enriched by the presence of the most progressive Ashkenazi newcomers, and surrounded by the Islamic and Christian majority populations in the private and public arena, strived to access the broader, more general framework of modern societal trends. Encouraged by examples from the immediate surroundings, by the national Yugoslav framework and the more developed Jewish municipalities within the state, through daily and varied interaction with neighbors and institutional contact, a metamorphosis of the local Jewish community was enabled. Internal changes were partially conditioned by intensifying relations with the non-Jewish communities. They mostly accompanied these relations and were their inevitable outcome. Parallel to the development of increasingly diverse and more frequent contacts which were pursued in order to self-develop, to maintain and improve interethnic relations, at the social level there erupted elements of interethnic intolerance based on political, religious or economic grounds. Antisemitism strained and, alongside other factors (internal tightness, popular mentality, national tradition, religious differences), additionally complicated and halted closer cooperation. Besides these disagreements, integration into Yugoslav society was complete, especially among the young generation, but only in extraordinary conditions did it end in assimilation, which was exclusively enabled by the newly arrived Jews coming from other, more open and more cosmopolitan environments. This paper will show and elaborate on numerous examples of private and social collaboration between Kosovo-Metohijan Jews and other nations in the given chronological framework that were, above all, of wider importance for regional development and establishing civilizational heritage. Relacje Żydów ze społecznością nieżydowską w Kosowie i Metochii między dwiema wojnami światowymi – od autocentryzmu do asymilacji Okres między dwiema wojnami światowymi w Kosowie i Metochii (1918-1941) to ważna epoka ochrony prawnej, rozwoju gospodarczego, samostanowienia narodowo-politycznego, emancypacji edukacyjno-kulturowej i ogólnego rozwoju tamtejszej społeczności żydowskiej. Wierna tradycji lokalna społeczność sefardyjska, wzbogacona o wpływy bardziej postępowych przybyszów aszkenazyjskich i otoczona w większości przez ludność islamską i chrześcijańską, w sferze prywatnej i publicznej aspirowała do wejścia na szerszą, ogólną ścieżkę współczesnych ruchów społecznych. Zachęcona przykładami z najbliższego otoczenia – ze strony narodów jugosławiańskich i bardziej rozwiniętych społeczności żydowskich w kraju, poprzez codzienne różnorodne obcowanie z sąsiadami i poprzez kontakty instytucjonalne, lokalna społeczność żydowska uległa metamorfozie. Zmiany wewnętrzne były częściowo uwarunkowane intensyfikacją stosunków ze światem nieżydowskim, z reguły podążały za tymi stosunkami i były ich nieuniknionym skutkiem. Równolegle z rozwojem coraz bardziej zróżnicowanych i częstszych kontaktów budujących, utrzymujących i poprawiających relacje międzyetniczne, na płaszczyźnie społecznej pojawiały się elementy nietolerancji międzyetnicznej, wynikającej z kontekstu politycznego, religijnego i ekonomicznego. Antysemityzm, oprócz kilku innych czynników (zamknięcie wewnętrzne, mentalność mieszkańców, tradycja ludowa, różnice wyznaniowe), dodatkowo obciążał i wstrzymywał jeszcze ściślejszą współpracę. Mimo tych sprzeczności integracja ze społeczeństwem jugosłowiańskim, zwłaszcza wśród młodego pokolenia, była pełna, ale tylko w wyjątkowych przypadkach kończyła się asymilacją, wyłącznie wśród nowo przybyłych Żydów, pochodzących z innych, bardziej otwartych i kosmopolitycznych środowisk. W artykule zostaną przedstawione i omówione liczne przykłady prywatnej i społecznej współpracy Żydów z Kosowa i Metochii z innymi narodami w podanych ramach chronologicznych, które miały przede wszystkim szersze znaczenie dla rozwoju regionalnego i postępu cywilizacyjnego.

Cisplatin (Cis-diamminedichloroplatinum II, CP) is an important chemotherapeutic agent, useful in the treatment of several cancers, but with several side effects such as nephrotoxicity. The present study investigated the possible protective effect of selenium (Se) against CP-induced oxidative stress in the rat kidneys. Male Wistar albino rats were injected with a single dose of cisplatin (7 mg CP/kg b.m., i.p.) and selenium (6 mg Se/kg b.m, as Na2SeO3, i.p.), alone or in combination. The obtained results showed that CP increased lipid peroxidation (LPO) and decreased reduced glutathione (GSH) concentrations, suggesting the CP-induced oxidative stress, while Se treatment reversed this change to control values. Acute intoxication of rats with CP was followed by statistically significant decreased activity of antioxidant defense enzymes: superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px), glutathione reductase (GR) and glutathione-S-transferase (GST). Treatment with Se reversed CP-induced alterations of antioxidant defense enzyme activities and significantly prevented the CP-induced kidney damage.

V italijanskih in agleških glasbenozgodovinskih virih iz druge polovice sedemnajstega stoletja srečujemo ime Giovanni Sebenico, ki se omenja kot zelo dober tenorist, kot orglavec, »maestro di capella« in končno kot skladatelj dveh oper. Ker je Sebenico živel določen čas v Benetkah in ker so najstarejši poznani podatki o njem iz tega mesta, so seveda vsi poznejši leksikografi mislili, da gre pač za skladatelja, ki je rojen v Benetkah. Vendar pa, kot se bo še nadalje pokazalo, pojma »Benetke« ni jemati ozko in tako ni treba misliti, da se nanaša na mesto tega imena. Tolmačiti ga je kot izraz, ki vključuje celo področje, in to tako današnje pokrajine tega imena kot ozemlje, ki je v tistem času bilo pod oblastjo Beneške republike.

Hydroxyapatite (HAp) has been the main protagonist in the quest for an ideal biomaterial for regenerative medicine over the last half a century. To control its properties, this material has commonly been doped with chemical elements other than its natural stoichiometric constituents: Ca, O, P, and H. Here, we report on the first analysis of the biological response to germanium-doped hydroxyapatite (Ge-HAp). Cytotoxicity, osteogenic differentiation induction, and colony formation potential were measured on dental pulp stem cells, while the antimicrobial effect was assessed against Gram-negative Escherichia coli , Gram-positive methicillin-resistant Staphylococcus aureus (MRSA), and Candida albicans. All analyses were run in comparison to Ge-free HAp. Cell viability was inversely dependent on the nanoparticle concentration and incubation time. Adding Ge to HAp reduced cell viability relative to HAp after 24–72 h incubation periods, but the effect was reversed after longer incubations, when the viability of cells treated with low doses of Ge-HAp exceeded that of HAp-treated cells and became comparable with control culture. Both HAp and Ge-HAp induced mineral formation in the cell culture, but the effect was more pronounced for Ge-HAp. Likewise, relative to both control cells and cells exposed to HAp, Ge-HAp upregulated the expression of all three osteogenic markers analyzed, namely, alkaline phosphatase, RUNX2, and osteocalcin, exerting the key influence on osteogenesis in its early, differentiation stage. The colony formation capacity of stem cells, however, was impaired by HAp and even more so by Ge-HAp. The antimicrobial effect was dependent on the microorganisms tested. Thus, whereas the antimicrobial activity was absent against E. coli , it was evident against MRSA and C. albicans. While the antibacterial activity against MRSA was weakened by the addition of Ge to HAp, the antimycotic activity against C. albicans was intensified with the addition of Ge. These findings demonstrate a significant potential of Ge-doped HAp nanoparticles in regenerative medicine due to their pronounced biocompatibility, osteoinductivity, and antimicrobial activity.
