Introduction: Aging is a natural, irreversible physiological process that depends on genetic, environmental, and lifestyle factors. Many physiological, biological, psychological, and other factors play a major role. According to the World Health Organization, falls are the second leading cause of unintentional injury death in the world and represent a major global public health problem. Falls are most commonly caused by intrinsic and extrinsic risk factors. A comprehensive assessment of fall risk is critical to the development of effective fall prevention programs. The screening protocol is brief, easy to use, and multifactorial and allows the identification of risk factors for falls. The aim of this study is to investigate the importance of the presence of risk factors in the home environment and the impact on increasing the risk of falls in people in the third age. Methods: The study was conducted in the municipality of Podgorica. 109 elderly people from urban and rural areas were included in the study using the snowball method. The instruments used in our study are a standardized checklist for assessing risk factors in the home environment, inside and outside the home (HASSAT), and a self-assessment scale of one’s own concern about a possible falls efficacy scale international. The survey was conducted from the end of October to the end of November 2023. Results: There is a statistically significant difference in social and physical activities of daily living in the area of concern about falling. When analyzing the overall result of the fear of falling scale in relation to gender, a significant statistical difference is found. The analysis of the individual rooms in relation to the age of the respondents shows that there is a significant statistical difference. Conclusion: The results obtained show that the high risk of falling is present in all rooms of the home environment for people in their 3rd year of life and that fear of falling increases with age.

A country's logistics performance, gauged aptly, can influence not just the business outcomes of individual enterprises but also shape the nation's holistic logistics efficacy. This study delves into an examination of logistics standards in European Union (EU) countries, viewed through the lens of the Logistics Performance Index (LPI) as reported by the World Bank. The primary focus is on the LPI data for 2023, with a subsequent exploration of the EU’s performance trajectory from 2007 to 2018. The findings illuminate that specific EU countries consistently uphold superior logistics proficiency, while striving for advancements. Beyond these front runners, many EU countries manifest commendable logistics outcomes, positioning themselves favorably on the global stage.

Introduction: Basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) are the most common skin malignancies in the heterogeneous group of non-melanoma skin cancer (NMSC). Due to increasing incidence these tumours remain significant health problem worldwide. Methods: We conducted retrospective analysis to evaluate the incidence of primary BCCs and SCCs in our institution from 2003 to 2022, and to correlate it with available clinical data. Results: We noticed that the incidence of NMSC increased between 2018 and 2022 (p<0.01). Among 1570 patients diagnosed with NMSC, BCC represented 77.9% of cases. BCC was constantly more common type of NMSC with statistically significant difference in the period from 2003-2005 and in the period from 2017- 2022 (p<0.01). Nodular subtype of the BCC was the most common, affecting primarily face. Superficial BCC occurred most commonly on trunk (p<0.01), affecting younger patients than the other histological subtypes (mean age 61.29±13.47 years (p<0.01). High-risk BCCs in men were more common on face and scalp (p<0.05). BCCs were predominantly smaller tumours (<2 cm) in contrast to SCCs with highest incidence in pT2-pT4 group (p<0.01). SCC patients were older (mean age 72.89±9.7) than BCC patients (mean age 65.15±12.80) (p<0.01). Conclusion: In order to improve prevention strategies and prevent further increase in incidence, there is need to develop current and exact registries of these malignancies, especially separately BCC and SCC.

Introduction: The diagnosis of coronavirus disease 2019 (COVID-19) disease is necessary for the further treatment of patients with the present symptoms, and molecular diagnostics is considered the gold standard. However, it is already known that patients with symptoms of the disease can have a negative test due to various factors. The purpose of this study is to evaluate the laboratory parameters in patients with symptoms of COVID-19 infection who have both positive and negative test results. Methods: The study included 101 samples from patients who tested positive for COVID-19 and 101 samples from patients who tested negative, both groups presenting symptoms of COVID-19. Data on the complete blood count, the absolute values of the differential blood count, and the D-dimer values were collected from the samples that were taken. Using blood count data, neutrophil-to-lymphocyte ratios, platelet-to-lymphocyte ratios, and systemic immune-inflammatory index (SII) were calculated. Results: Based on the examination and research, a significant increase and change in the values of inflammatory indices and D-dimer were determined. In addition to the increase of these values above the reference value, a positive correlation was confirmed between the inflammation index value and the D-dimer value. Conclusion: COVID-19-negative patients with characteristic symptoms of COVID-19 had higher values of lymphocytes and the determination of platelets and SII in these patients can be added to the diagnostic algorithm.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the rapidly evolving RNA virus behind the COVID-19 pandemic, has spawned numerous variants since its 2019 emergence. The multifunctional NSP14 enzyme, possessing exonuclease and mRNA capping capabilities, serves as a key player. Notably, single and co-occurring mutations within NSP14 significantly influence replication fidelity and drive variant diversification. This study comprehensively examines 120 co-mutations, 68 unique mutations, and 160 conserved residues across NSP14 homologs, shedding light on their implications for phylogenetic patterns, pathogenicity, and residue interactions. Quantitative physicochemical analysis categorizes 3953 NSP14 variants into three clusters, revealing genetic diversity. This research underscores the dynamic nature of SARS-CoV-2 evolution, primarily governed by NSP14 mutations. Understanding these genetic dynamics provides valuable insights for therapeutic and vaccine development.

Otvoreni obrazovni sadržaji su značajan i opravdan predmet interesovanja visokoškolskih biblioteka, a posebno nakon pojave globalne pandemije COVID-19, koja je prouzrokovala brojne promjene u sistemu visokoškolskog obrazovanja, kojima su se visokoškolske biblioteke morale prilagoditi, kako bi nastavile davati potrebnu značajnu podršku naučnoistraživačkom i obrazovnom procesu na visokoškolskim institucijama. S tim u vezi, cilj ovoga istraživanja je utvrditi u kojoj mjeri visokoškolske biblioteke Univerziteta u Sarajevu pružaju usluge povezane sa otvorenim obrazovnim sadržajima, koje su, prema mišljenju bibliotekara, prednosti uvođenja takvih usluga i kako se iste mogu dodatno unaprijediti u postpandemijskom okruženju. Rezultati istraživanja pokazuju da anketirane biblioteke nude određene usluge povezane sa otvorenim obrazovnim sadržajima, ali i da u uvođenju takvih oblika usluga bibliotekari nailaze na izvjesne prepreke, u vezi s kojima se posebno izdvajaju sigurna i dugoročna pohrana otvorenih obrazovnih sadržaja, te neprepoznavanje značajne uloge visokoškolskih bibliotekara u inicijativama otvorenih obrazovnih sadržaja.

Background Plant-beneficial bacterial inoculants are of great interest in agriculture as they have the potential to promote plant growth and health. However, the inoculation of the rhizosphere microbiome often results in a suboptimal or transient colonization, which is due to a variety of factors that influence the fate of the inoculant. To better understand the fate of plant-beneficial inoculants in complex rhizosphere microbiomes, composed by hundreds of genotypes and multifactorial selection mechanisms, controlled studies with high-complexity soil microbiomes are needed. Results We analysed early compositional changes in a taxa-rich natural soil bacterial community under both exponential nutrient-rich and stationary nutrient-limited growth conditions (i.e. growing and stable communities, respectively) following inoculation with the plant-beneficial bacterium Pseudomonas protegens in a bulk soil or a wheat rhizosphere environment. P. protegens successfully established under all conditions tested and was more abundant in the rhizosphere of the stable community. Nutrient availability was a major factor driving microbiome composition and structure as well as the underlying assembly processes. While access to nutrients resulted in communities assembled mainly by homogeneous selection, stochastic processes dominated under the nutrient-deprived conditions. We also observed an increased rhizosphere selection effect under nutrient-limited conditions, resulting in a higher number of amplicon sequence variants (ASVs) whose relative abundance was enriched. The inoculation with P. protegens produced discrete changes, some of which involved other Pseudomonas . Direct competition between Pseudomonas strains partially failed to replicate the observed differences in the microbiome and pointed to a more complex interaction network. Conclusions The results of this study show that nutrient availability is a major driving force of microbiome composition, structure and diversity in both the bulk soil and the wheat rhizosphere and determines the assembly processes that govern early microbiome development. The successful establishment of the inoculant was facilitated by the wheat rhizosphere and produced discrete changes among other members of the microbiome. Direct competition between Pseudomonas strains only partially explained the microbiome changes, indicating that indirect interactions or spatial distribution in the rhizosphere or soil interface may be crucial for the survival of certain bacteria.

Background: Optical coherence tomography (OCT) is a biomarker of neuroaxonal loss in multiple sclerosis (MS). Objective: The objective was to assess the relative role of OCT, next to magnetic resonance imaging (MRI) and serum markers of disability in MS. Methods: A total of 100 patients and 52 controls underwent OCT to determine peripapillary retinal nerve fiber layer (pRNFL) and ganglion cell-inner plexiform layers (GCIPL). Serum neurofilament light chain (sNfL), total lesion volume (TLV), and brain parenchymal fraction (BPF) were also assessed. The associations of OCT with disability were examined in linear regression models with correction for age, vision, and education. Results: In patients, pRNFL was associated with the Symbol Digit Modalities Test (SDMT; p = 0.030). In the multivariate analysis including sNfL and MRI measures, pRNFL (β = 0.19, p = 0.044) and TLV (β = −0.24, p = 0.023) were the only markers associated with the SDMT. pRNFL (p < 0.001) and GCIPL (p < 0.001) showed associations with the Expanded Disability Status Scale (EDSS). In the multivariate analysis, GCIPL showed the strongest association with the EDSS (β = −0.32, p < 0.001) followed by sNfL (β = 0.18, p = 0.024). Conclusion: The associations of OCT measures with cognitive and physical disability were independent of serum and brain MRI markers of neuroaxonal loss. OCT can be an important tool for stratification in MS, while longitudinal studies using combinations of biomarkers are warranted.

Abstract Unfounded—conspiracy and health—beliefs about COVID-19 have accompanied the pandemic worldwide. Here, we examined cross-nationally the structure and correlates of these beliefs with an 8-item scale, using a multigroup confirmatory factor analysis. We obtained a two-factor model of unfounded (conspiracy and health) beliefs with good internal structure (average CFI = 0.98, RMSEA = 0.05, SRMR = 0.04), but a high correlation between the two factors (average latent factor correlation = 0.57). This model was replicable across 50 countries (total N = 13,579), as evidenced by metric invariance between countries (CFI = 0.96, RMSEA = 0.06, SRMS = 0.07) as well as scalar invariance across genders (CFI = 0.98, RMSEA = 0.04, SRMS = 0.03) and educational levels (CFI = 0.98, RMSEA = 0.04, SRMS = 0.03). Also, lower levels of education, more fear of COVID-19, and more cynicism were weakly associated with stronger conspiracy and health beliefs. The study contributes to knowledge about the structure of unfounded beliefs, and reveals the potential relevance of affective (i.e., fear of COVID-19) and cognitive (i.e., cynicism) factors along with demographics, in endorsing such beliefs. In summary, we obtained cross-cultural evidence for the distinctiveness of unfounded conspiracy and health beliefs about COVID-19 in terms of their structure and correlates.

New 1,2,3-triazolo(thieno)stilbenes were synthesized as mixtures of isomers and efficiently photochemically transformed to their corresponding substituted thienobenzo/naphtho-triazoles in high isolated yields. The resulting photoproducts were studied as acetyl- (AChE) and butyrylcholinesterase (BChE) inhibitors without or with interconnected inhibition potential of TNF-α cytokine production. The most promising anti-inflammatory activity was shown again by naphtho-triazoles, with a derivative featuring 4-pentenyl substituents exhibiting notable potential as a cholinesterase inhibitor. To identify interactions between ligands and the active site of cholinesterases, molecular docking was performed for the best potential inhibitors. Additionally, molecular dynamics simulations were employed to assess and validate the stability and flexibility of the protein–ligand complexes generated through docking.

Heavy metals as environmental pollutants can have natural or anthropogenic origin. To determine the river sediment pollution status, it is crucial to have appropriate reference samples, free of anthropogenic impact, and natural reference samples should be used wherever and whenever possible. The collection of reference samples should be performed in the vicinity of the research area in a place that belongs to the same geological environment and is undisturbed by human activity. The main purpose of this study was to compare concentrations of heavy metals from different rivers with background values to show that the usage of natural background values is the best option when assessing pollution status, but also to underline that the natural background values have to correspond to the analyzed sediments. In this study, 5 river sediments from Sava, 17 from Great War Island (GWI), 11 from Danube, 24 from Tisa, 47 from Tamiš, and 11 from Timok were evaluated relative to reference samples from the Sava and Tisa Rivers. The results indicate that geological origin has a strong influence on the content of heavy metals in river sediments, primarily regarding concentrations of Ni and Co. Furthermore, Tamiš, Tisa, Sava, and Danube sediments are under strong anthropogenic influence.

AbstractEducation plays a key role in the development of human civilisation. Learning and teaching methods are still evolving and undergoing numerous changes as a result of scientific knowledge and revolutionary ideas of stakeholders in the education system, and the development of advanced technologies. We are all familiar with traditional ways of learning wherein educational process is conducted in such a way that the focus is primarily on content. Jan Amos Komensky, the alpha and omega of education science, laid out the class-subject-lesson traditional education system and designed, as early as the 17th century, the school as an institution capable of meeting the mass educational demands of the time. Because these traditional methods use repetition and memorisation of information as the principal means of acquiring knowledge, students are unable to develop their critical thinking, problem-solving and decision-making skills. In the 21st century, teaching should be focused on the effective cooperation between teachers and students who are actively participating in the teaching process, because such an approach ensures the training of innovative individuals who go on to become qualified professionals and responsible citizens, thus creating a more affluent and safer society in general. This paper provides an overview of the important characteristics of modern schools, as well as some modern teaching strategies. Keywords: modern teaching strategies, quality of teaching, teaching--- SažetakObrazovanje ima ključnu ulogu u razvoju ljudske civilizacije. Metode učenja i poučavanja još uvijek se neprestano razvijaju i prolaze kroz brojne promjene zahvaljujući znanstvenim spoznajama, revolucionarnim idejama osoba uključenih u obrazovni sustav kao i razvoju naprednih tehnologija. Svi smo dobro upoznati s tradicionalnim načinima učenja u kojima se obrazovanje provodi tako da je fokus usmjeren na sadržaj. Jan Amos Komensky, alfa i omega pedagoške znanosti, tvorac razredno-predmetno-satnoga tradicionalnog sustava obrazovanja, već je u 17. stoljeću osmislio školu kao instituciju primjerenu zahtjevima tadašnjega vremena za masovnim obrazovanjem. Budući da te tradicionalne metode koriste ponavljanje i pamćenje informacija kao temeljni način stjecanja znanja, učenici ne razvijaju svoje kritičko razmišljanje, vještine rješavanja problema i donošenja odluka. Nastava u 21. stoljeću treba biti usmjerena na učinkovitu suradnju nastavnika i učenika koji su aktivno uključeni u nastavni proces jer takav pristup osigurava osposobljavanje inovativnih pojedinaca koji postaju kvalitetni stručnjaci i odgovorni građani te na takav način stvaraju bogatije i sigurnije društvo u cjelini. U ovom radu dan je pregled bitnih obilježja suvremene škole, kao i nekih suvremenih nastavnih strategija.Ključne riječi: kvaliteta nastave, nastava, suvremene nastavne strategije
