Abstract Pike-perch Sander lucioperca is a native species originally present in the Black Sea basin of Bosnia and Herzegovina. In the 1990s, it was introduced to the Neretva River and its reservoir system, and since 2009 the species has been recorded in Lake Boračko and Buško Blato Reservoir. The aim of this study is to analyse the distribution of S. lucioperca in Bosnia and Herzegovina based on literature data (1975–2024) and to define areas where the species has been introduced in order to assess the risk of potential invasiveness. The results indicate that S. lucioperca belongs to the high-risk category. Since the same risk ranking has been confirmed in recent studies on aquatic ecosystems in other geographical areas, the conclusion is that pike-perch could soon pose a potential threat to native species and aquatic ecosystems in Bosnia and Herzegovina if mitigation measures are not implemented.

Budući da filmski dijalozi odražavaju šire društvene i kulturne identitete te pridonose diskursu o identitetu unutar filmske umjetnosti, ovo istraživanje nastoji pružiti uvid u složenu interakciju između jezika, identiteta i filmske naracije u filmu Trči, Lola, trči (Lola rennt) redatelja Toma Tykwera iz 1998. godine. Naime, filmski dijalozi u ovome njemačkom, višestruko nagrađivanom filmu pokazuju zanimljivu putanju u kreiranju i oblikovanju identiteta glavnih likova, pri čemu se dijalog ne koristi samo kao narativni mehanizam nego i kao sredstvo za istraživanje i prezentaciju identiteta. Cilj je rada utvrditi kako dijalozi pridonose razvoju narativa te aktivno sudjeluju u konstrukciji kompleksnih identiteta protagonista. Osim toga, analizom pojedinih primjera potkrijepit će se kako jezik koji likovi koriste, njihov izbor riječi, ton te kontekst u kojemu se dijalozi odvijaju služe kao snažni alati u kreiranju identiteta, pri čemu zanimljive ponavljajuće dijaloške sekvence oblikuju specifičan odnos među njima. Ključne riječi: identiteti, filmski dijalozi, likovi, naracija, jezik

Background/Objectives: Syncope is a common clinical occurrence, with neurally mediated and orthostatic types accounting for about 75% of cases. The exact pathophysiological mechanisms remain unclear, with recent evidence suggesting autonomic nervous system damage and a potential infectious etiology. This study aimed to examine the role of infection in the development of syncope and orthostatic hypotension (OH). Methods: The cross-sectional study included 806 patients from the Neurocardiological Laboratory of the Institute for Cardiovascular Diseases “Dedinje”. Patients were divided into three groups: unexplained recurrent syncope (n = 506), syncope with OH during the head-up tilt test (HUTT) (n = 235), and OH without a history of syncope (n = 62). All participants underwent the HUTT, and 495 underwent serological testing for various microorganisms. Data were analyzed using chi-squared tests and binary and multinomial logistic regression. Results: The HUTT was positive in 90.6% of patients with syncope and OH, compared with 61.6% with syncope alone (p < 0.001). Serological testing revealed that 57.85% of syncope patients, 62.9% of syncope with OH patients, and 78% of OH patients had positive IgM antibodies to at least one microorganism. Multivariate analysis indicated that IgM antibodies to Coxsackievirus and Epstein–Barr virus were significant predictors of OH. Conclusions: This study demonstrated a potential association between infections and syncope/OH. Further investigation into the role of infectious agents in autonomic dysfunction is warranted to clarify the underlying mechanisms of syncope and OH.

Abstract The adoption of the United Nations General Assembly Resolution A/RES/78/282, designating 11 July as the International Day of Reflection and Commemoration of the 1995 Srebrenica genocide, embodies a significant effort in combating genocide denial. However, the Resolution generated substantial preemptive and reactive backlash, sparked by a global network of actors committed to revising the history of the 1990s. This article provides a detailed account of the resolution’s contextual history within the UN, as well as an analysis of the geopolitical and ideological underpinnings of Srebrenica genocide denial as a tool of regional nationalist and revisionist agendas. As a salient example, the article explores the coordinated campaign led by Serbia and Republika Srpska to undermine the resolution, utilizing it to mobilize nationalist tropes, discredit international institutions, and reinforce denialist narratives.

Introduction: Aneurysms of brain vessels are life-threatening conditions with various adverse outcomes, some stemming from microsurgical intervention, particularly when major vessel perforators are inadequately protected. The use of endoscopes enhances the approach to aneurysms by providing closer visualization (180–360 degrees) of the local anatomy, potentially reducing accidental damage. To improve visualization and efficiency, a microscope-integrated 45-degree angled microinspection endoscopic tool (QEVO®, Carl Zeiss, OberkochenTM) has been developed and employed in various neurosurgical procedures. Methods: Between 2021 and 2025, 27 brain aneurysms were treated with QEVO® assistance at the Department of Neurosurgery, Clinical Center of the University of Sarajevo. The choice of the videos corresponds to the best image quality in videos and on the microscopic determination of adjacent vessel perforators, which were not adequately seen purely by the surgical microscope in specific cases. Exclusion criteria included cases without a need for QEVO® assistance in perforator visualization, severe brain edema, intraoperative aneurysm rupture, posterior circulation, or low video quality. Results: Case 1 demonstrates an anterior choroidal artery (AchA) aneurysm; Case 2 presents an anterior communicating artery (AcommA) aneurysm; and Case 3 features contralateral middle cerebral artery (MCA) microsurgical clipping with QEVO® assistance. Conclusions: The QEVO® tool significantly improves the visualization of aneurysm–perforator relationships, increasing the likelihood of preserving perforators during standard microsurgical clipping. This innovative approach may reduce surgical complications and enhance patient outcomes, highlighting the tool’s potential as an adjunct in aneurysm microsurgery.

This is the first study of microelement variability in needles of seven natural populations of Picea omorika (Panč.) Purkyně from Serbia. Seven essential, three usefull, and six toxic microelements were analysed by ICP-Spectrometer. Their range was as follows: Mn > Fe > Zn > Al > Na > B > Cu > Ni > Cr > Cd > Co. The microelements Mo, As, Hg, Pb and Se were detected in traces. The amounts of Al, B, Co, Cr and Na were recorded in P. omorika needles for the first time. Among usefull microelements the most abundant was Al, while among toxic it was Cr. The most southern population, Mileševka canyon, had the highest amounts of Zn, Cu, Ni, Co and Cd and the lowest values of B. Discriminant and cluster analyses visualized that this population also showed the greatest separation from all other populations. Further research could usefully explore factors that affect the endangerment of P. omorika in its natural habitats or prevent its natural regeneration.
