Immersive virtual reality (IVR) can heighten presence and enable active, embodied interaction in realistic 3D environments, which has been associated with potential benefits in physics education. This article presents a comprehensive review of immersive virtual reality implementation in physics education at both school and university levels. The analysis included 34 studies indexed in Scopus and ERIC, published between January 1, 2018, and June 1, 2025. Methodologically, this review followed a PRISMA approach. IVR implementations for physics learning were assessed, topic-aligned activity types were summarized, and associated opportunities and challenges were documented. Findings indicate that IVR can support physics learning by providing complementary visualizations, optimizing cognitive load, enabling haptic learning, saving time, and fostering collaborative inquiry. Conversely, the most frequent potential IVR challenges include discomfort, unreliable interaction, orchestration issues, relatively high costs, and significant extraneous cognitive load.

Wildlife–vehicle collisions (WVCs) represent a growing safety, ecological, and economic challenge, with direct consequences for human lives, material damage, and biodiversity conservation. In the Federation of Bosnia and Herzegovina, systematic analyses that link traffic accidents caused by collisions with wildlife are lacking. This research identifies high-risk locations of WVCs and applies geospatial analysis to the main roads of the Federation of Bosnia and Herzegovina. The analysis is based on official police reports documenting 14,169 traffic accidents between 2021 and 2023, of which 104 cases (0.73%) were classified as animal-related. Although species were not specified in the reports, these accidents predominantly occurred in areas where wildlife crossings are expected, and thus are treated as potential wildlife–vehicle collisions. The results indicate a concentration of WVCs in nine municipalities, with eight critical road segments identified on main roads. Additional analyses explored the relationship between collisions, road infrastructure (bridges, tunnels), and ecological features of habitats (Emerald Network, Natura 2000, Red List of FBiH, IUCN). Based on the findings, it can be concluded that spatially targeted prevention is essential, with priority given to infrastructural measures (wildlife overpasses, fencing, signage) and strategic measures (improved databases, continuous monitoring, and integration into spatial planning). The obtained results provide a foundation for policies that simultaneously enhance traffic safety and contribute to the protection of wildlife populations.

BACKGROUND Acute hyperglycemia is frequently observed in patients presenting with acute coronary syndromes and is considered a marker of metabolic and neurohormonal stress. However, its prognostic significance relative to chronic glycemic status remains incompletely understood, particularly in patients with non-ST-segment elevation myocardial infarction (NSTEMI). Glycated hemoglobin (HbA1c) reflects long-term glycemic control but may not adequately capture acute metabolic derangements occurring during myocardial ischemia. Stress hyperglycemia reflects a transient metabolic response to acute illness mediated by counter-regulatory hormones, systemic inflammation, and increased hepatic gluconeogenesis, and does not necessarily indicate pre-existing insulin resistance or chronic dysglycemia. Recent studies suggest that stress-related hyperglycemia indices may better reflect short-term risk, yet comparative data in NSTEMI populations remain limited. AIM To determine whether admission stress hyperglycemia indices are associated with early mortality in patients with non-ST elevation myocardial infarction. METHODS This prospective, single-center observational study consecutively enrolled 171 patients admitted with confirmed NSTEMI. Stress hyperglycemia was assessed using the stress hyperglycemia ratio (SHR) and the admission glucose-to-chronic glycemia ratio (ACGR), calculated from admission plasma glucose and HbA1c values obtained at hospital presentation. Patients were categorized according to established HbA1c thresholds. Clinical, laboratory, and echocardiographic data were systematically collected. All patients were followed for three months after discharge. The primary endpoint was the occurrence of major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, or urgent coronary revascularization. The secondary endpoint was all-cause mortality. Discriminatory performance was evaluated using receiver operating characteristic (ROC) curve analysis. Multivariable logistic regression models were constructed to assess the independent and incremental prognostic value of stress hyperglycemia indices before and after adjustment for established clinical and echocardiographic predictors. RESULTS During the three-month follow-up period, 88 MACE and 25 deaths were recorded. HbA1c categories were not significantly associated with all-cause mortality or MACE. In contrast, admission glucose levels, SHR, and ACGR were significantly higher in non-survivors than in survivors. No significant differences in HbA1c were observed between outcome groups. Stress hyperglycemia indices demonstrated modest discriminatory ability for predicting mortality and showed greater discrimination than HbA1c in ROC analyses. In multivariable models, both SHR and ACGR remained independently associated with early mortality after adjustment for demographic, clinical, and echocardiographic variables, whereas no independent association with the composite MACE endpoint was observed. ROC-derived thresholds used for survival analyses were exploratory and have not been externally validated. CONCLUSION In patients with NSTEMI, stress hyperglycemia indices assessed at hospital admission are independently associated with early mortality, whereas chronic glycemic status shows limited prognostic relevance. These indices appear to reflect acute systemic stress and metabolic instability and may provide clinically useful information for early risk stratification during the initial phase of hospitalization, particularly when comprehensive echocardiographic assessment is not yet available.

As a part of the Gene Bank of the Republic of Srpska, within the Institute of Genetic Resources, University of Banja Luka, field collections of autochhthonous fruit and grape varieties serve as a valuable resource for diverse scientific research, experimental studies, measurements, and long-term monitoring. In ripening season of 2024, we counducted research on traditional autochthonous apple varieties. From field collections, we selected 3 apple accsessions with good yield potential, for sampling. The apple varieties included in this study were Bjeličnik, Vidovka žuta and Kanada Švabica.  After color analyses was done, we concucted analyses of antioxidant potential in samples. Methods used for color were the LAB digital color positioning system and for antioxidant potential, it was determined using the DPPH free radical sequencing method. Results showed that EC50 value of 18.60 mg/mL places 'Vidovka žuta' at the top of the studied varieties for antioxidant potential. 'Bjeličnik' is interesting variety in the pomology of Republika Srpska, named for its characteristic pale, almost white skin (EC50 =24.19 mg/mL). Kanada švabica showed EC50 of 31.87 mg/mL, and suggests a lower relative antioxidant potency compared to 'Vidovka žuta' and 'Bjeličnik'. Color showed that Bjeličnik is also significantly lighter than the others, confirming its phenotype as the "white" apple of the collection. Yellowness (b*) indicated that Vidovka žuta and Kanada švabica are statistically similar in their yellow intensity, while Bjeličnik is significantly less yellow. Traditional apples are a rich source of dietary antioxidants. The high uniformity in 'Bjeličnik' and the superior potency of 'Vidovka žuta' justify their use in breeding programs targeting increased functional value in modern apple cultivars.

This translational synthesis highlights the potential role of obesity-induced low-grade chronic inflammation in modulating clinical outcomes among patients with spondyloarthritis (SpA). Obesity transforms adipose tissue into a pro-inflammatory endocrine organ, where hypertrophic adipocytes release adipokines such as leptin alongside cytokines including TNF-α and IL-6, potentially contributing to macrophage polarization toward an M1 phenotype and activating NF-κB signaling pathways. This systemic immunometabolic priming may lower activation thresholds at the enthesis—the primary pathological site in SpA—potentially amplifying IL-23/IL-17 axis activity via Th17 bias, innate-like lymphocyte responses, and stromal–immune crosstalk under mechanical stress. Clinically, patients with SpA and obesity have been reported to demonstrate heightened disease activity (BASDAI, ASDAS), impaired function (BASFI), accelerated radiographic progression (syndesmophytes, enthesophytes), and diminished biologic response rates, potentially attributable to pharmacokinetic alterations (e.g., subtherapeutic TNF inhibitor levels) and pharmacodynamic resistance. Multisystem comorbidities, including non-alcoholic fatty liver disease, cardiovascular events, metabolic syndrome, sleep disturbances, and depression, further exacerbate morbidity and diminish quality of life. Therapeutic implications emphasize obesity as a modifiable disease modifier. Weight loss interventions, including hypocaloric diets, anti-inflammatory regimens (e.g., Mediterranean diet), multicomponent exercise, GLP-1 receptor agonists, and bariatric surgery, have been associated with reductions in inflammatory biomarkers, improved remission rates (MDA, DAPSA), and prolonged drug survival by restoring adipokine balance and disrupting mechano-inflammatory loops. Future randomized controlled trials should prioritize long-term evaluations of integrated multidisciplinary strategies that combine metabolic optimization with immunomodulatory therapies, addressing adherence challenges through psychological support and patient-tailored protocols, while elucidating dose–response relationships for GLP-1RAs and exercise in diverse SpA subtypes to establish precision management paradigms that mitigate cardiometabolic burden and improve holistic outcomes.
