Introduction: 2,4-Diaminobutyric acid (2,4-DABA) is an excitatory amino acid with neurotoxic, hepatotoxic, and potentially carcinogenic effects, found in aquatic ecosystems with a tendency to accumulate in plants and animals. Due to its potential impact on development, its embryotoxicity is being studied. Zebrafish (Danio rerio), with high homology to the human genome, serve as an excellent model for studying development and developmental abnormalities. Objective: To investigate the effect of 2,4-DABA on proteins crucial for zebrafish eye development using molecular docking. Methods: Proteome screening was conducted using the FINDSITEcomb software, selecting 1119 proteins based on homology, tissue specificity, and expression timing. Six proteins that met the criteria were analyzed using molecular docking in the AutoDock Vina program. Results: The interaction of the fzd8a protein with 2,4-DABA showed the lowest Gibbs free energy value of -4.6 kCal/mol, while the interaction with the pbx4 protein had the highest value of -3.4 kCal/mol. A similarity was observed in the amino acid sequence of proteins that bind to 2,4-DABA, particularly in those containing an -SH group. Conclusion: 2,4-DABA may affect eye structure development in zebrafish by interacting with proteins throughout the entire development period. The results of in silico analyses provide a basis for further in vivo research, which should be conducted on live embryos to confirm these findings.

Introduction/Aim: Procaine is a local anesthetic from the amino ester group that blocks voltage-gated sodium channels. Since it can cross the placenta in its ionized form, its potential impact on embryonic development is of concern. Zebrafish, which have a significant degree of homology with the human genome, allow for the study of cardiovascular system development with reliable extrapolation to humans. Investigation of the effects of procaine on key proteins involved in zebrafish heart development using molecular docking. Methods: First, a screening of the interaction between procaine and the entire human proteome was performed using FINDSITEcomb software. Based on significant interactions with a high degree of analysis precision, 113 proteins were selected. Using the ZFIN database, the degree of homology between the selected human proteins and zebrafish proteins, tissue specificity, and expression timing were determined. Nine proteins met all the criteria: kcnh6a, kcnh7, kcnh5a, kcnh2a, psen2, rbfa, and zfpl1, and were further investigated through molecular docking in the AutoDock Vina program. Results: Most of the proteins were highly expressed during the blastula stage. Docking results showed that the scn1laa protein and procaine had the lowest Gibbs free energy value (-6 kCal/mol), while the zfp11 protein had the highest value (-4.4 kCal/mol). Procaine binding to the tested proteins revealed similar amino acid sequences within the same protein family. Conclusion: Procaine interacts with proteins involved in zebrafish heart development under in silico conditions. Further analyses on live embryos are needed to complement these findings.

Myocardial infarction (MI) is a serious cardiovascular disease and the primary cause of mortality, with a complex etiopathology. Identifying the genetic basis of myocardial infarction (MI) is essential for developing personalized medical treatments. This study examined the possible association between polymorphisms in the methylenetetrahydrofolate reductase (MTHFR) gene and MI. In the study, 120 patients with MI and 120 age-and-sex-matched controls were genotyped for C677T and A1298C MTHFR polymorphisms by the allele-specific or amplification refractory mutation systempolymerase chain reaction (ARMS-PCR). In the case of the C677T polymorphism, the T/T and C/T genotypes were associated with a significantly increased risk of MI under the dominant genetic model (odds ratio (OR)=2.060; P=0.006). Although there was no significant association between the A1298C variant and MI, this polymorphism was linked to a higher level of creatinine in MI patients (P<0.002). A similar association was observed for the C677T polymorphism (P=0.003). An A-T haplotype represented an increased risk for MI (OR=1.630; P=0.014), whereas the A-C haplotype had a protective role (R=0.517; P=0.002). These findings indicate that C677T MTHFR polymorphism is strongly associated with and increased risk of MI, making it a potential genetic risk factor and a possible predictor of MI.

In medieval Bosnia, the existence of a unified legal code that defined the legal principles, duties, and obligations of the parties involved in a particular dispute was not recorded. One of the most significant relationships in the history of medieval Bosnia was the relationship between the ruler and the nobility. The rights and obligations of the nobles in relation to the ruler in the medieval Bosnian state were defined through the institution of "faithful service" on one side and "noble faith" on the other. Simply put, as long as the nobles faithfully served the ruler, they were secure and their possessions were protected. This article focuses on instances of treason against the ruler and the judicial body responsible for investigating charges and delivering judgments according to established legal customs. The nobles mentioned in the Bosnian charters played a role in defining the relationship between the ruler and the respective noble, as did members of the hierarchy of the Bosnian Church. The Bosnian Church was a religious institution formed in the territory of Bosnia after the displacement of the Catholic diocese in the mid-13th century and was first mentioned in the 1320s. It was considered a heretical movement by the Roman Church, and its followers were excommunicated. It was accepted by the Bosnian ruling dynasty of Kotromanić and by the majority of noble families. From the perspective of neighboring states, the hierarchy of this church was considered to be the authority characterized by exceptional moral values. The aim of this article is to provide the research results regarding the role of the head (djed) of the Bosnian Church in determining the culpability of Bosnian nobles during the 14th and 15th centuries.

This study aims to assess and monitor the health of an urban protected area by analyzing the levels of persistent organic pollutants (POPs) and mercury (Hg) in soil and sediments. Based on the results, the detected concentrations of organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), and Hg are above the threshold maximum values for soils, and the prescribed target values for sediments. In the investigated protected area PCBs pose a very high ecological risk. The presence of 16 priority PAHs in analyzed soils and sediments poses a moderate to high cancer risk and Hg poses a considerable health risk to children. The research suggests that preserving urban protected areas is crucial for environmental and urban sustainability. In urban environments these areas should be evaluated in terms of their environmental, eco-geochemical, economic, and socio-cultural dimensions. The value of the existence of this natural oasis lies in its aesthetic and psycho-hydrological impact, local climate regulation, residential isolation, and significant art-architectural and horticultural shaping. The connection between eco-geochemical and management practices, planning, and urban green spaces policy should become an adopted innovation in the cities in the future.

Since the 1960s, the rapid advancement of information technology (IT) infrastructure has been covered by the innovation of new electronic devices. This progress has not only accelerated industrial growth but also enhanced the quality of human life. Modern electronic devices are highly advanced and contain numerous components. Traditionally, Sn-Pb solder alloys have been the preferred choice due to their many advantages, such as ease of use, low melting point, favorable working conditions, good ductility, and excellent wetting properties on copper and its alloys. However, due to the toxic effects of lead on both health and the environment, limit the use of lead. As a result, the development of lead-free solder alternatives has been a focus for the past thirty years. To investigate new solder materials extensively, it's crucial to understand phase diagrams, phase equilibria, and melting points. Thermodynamic calculations and modeling are key in producing a consistent dataset and predicting thermodynamic properties. Muggianu Model and Model Toop were used to calculate the thermodynamic properties of Al-Ga-Sn liquid alloys. The predicted values were compared with the calculated results of the General Solution Model, and published experimental data confirm that the models are both accurate and practical.

: This study explores the accessibility of critical infrastructures (CRITIS) in urban planning, focusing on the City of Sarajevo. CRITIS, essential for societal functioning, encompasses diverse services vital to social, economic, political, health, educational, and administrative systems. The authors leverage geographic information system (GIS) tools to construct an accessibility model for Sarajevo, analysing the spatial availability of critical functions. Six groups of CRITIS indicators, composed of 29 CRITIS elements, were used in the derivation of critical infrastructure accessibility index. The methodological framework was based on implementation of network GIS analysis, interpolation method (IDW) and GIS multi-criteria analysis, which could be applicable to similar research studies. Local communities concentrated in the strict urban core (Ferhadija, Baščaršija) have the best accessibility of CRITIS, while peripheral local communities with a large area, such as Mošćanica and Reljevo, have the lowest. Results suggest a zonal categorization of the urban area, providing valuable insights for spatial planning and future urban development management. The study reveals that the highest value of CRITIS accessibility doesn't necessarily align with the most densely populated areas at local community level.

Background: Radical surgical resection for pancreatic head carcinoma offers a chance for cure but unfortunately is only available to a limited number of patients. For a significant number of patients, palliative surgery remains the only option. The question of the most effective approach for patients with borderline resectable pancreatic head carcinoma (BRPHC) remains unresolved. Objective: The aim of the study was to compare the morbidity and mortality following R1 duodenocephalic pancreatectomy and double palliative bypass to explore the most optimal surgical treatment for patients with BRPHC. Methods: Our retrospective cohort study included 64 patients with BRPHC who underwent surgery from 2012 to 2019, with postoperative follow-up for three years. Morbidity and mortality parameters were examined based on the type of surgical treatment: R1 duodenocephalic pancreatectomy or palliative double bypass. Chi-square test, univariate regression, and Kaplan-Meier analysis were used as basic statistical methods in the analysis of the results. Results: Patients undergoing R1 duodenocephalic pancreatectomy had a 3.69 times higher risk of developing biliary leak (p=0.039; 95%CI:1.066, 1.181) and shorter survival compared to those undergoing palliative double bypass (p=0.022). No statistically significant association was found between the type of surgical procedure and other postoperative complications. Conclusion: Our study suggests that the double palliative bypass procedure may be a better option than R1 resection for patients with BRPHC.

Background: Colorectal cancer (CRC) is the third most common malignancy and the second leading cause of cancer-related deaths worldwide. Studies often consider colon and rectal cancers together. The combination of CA 19-9 and CEA markers is used to improve diagnostic accuracy, but there are no reports on the use of this combination as a prognostic predictor for CRC. The study by Kamada et al. was the first to use the "tumor marker index" (TMI), the geometric mean of normalized CEA and CA 19-9 in CRC, demonstrating the prognostic capabilities of this novel marker. However, it is not known how the preoperative value of TMI compares and fits into the current system of prognostic factors for preoperative prediction of overall survival (OS) and disease-free survival (DFS). Objective: The aim was to investigate the significance of preoperatively determined TMI in predicting three-year overall survival (3Y-OS) and three-year disease-free survival (3Y-DFS) in patients with stage III adenocarcinoma of the upper and middle rectum. Methods: Our retrospective cohort study included 93 patients who underwent open anterior resection of the rectum between January 2015 and December 2020. Optimal cut-off values of the markers were determined by ROC analysis. Statistical analysis was performed using IBM SPSS Statistics 22 and R 4.4.0. Results: Patients with TMI ≥1.0158 had a statistically significantly higher likelihood of mortality within three years (p=0.012). Patients with TMI ≥0.979 had a statistically significantly higher likelihood of disease-free survival of less than three years (p=0.003). Compared to CEA and CA 19-9, TMI had the highest AUC for predicting 3Y-OS (0.740, p=0.020) and 3Y-DFS (0.780, p=0.012). Adding TMI to other predictors increased the AUC for predicting both 3Y-OS (from 0.748 to 0.853) (p=0.001) and 3Y-DFS (from 0.711 to 0.850) (p=0.001). Conclusion: Our study confirmed previous findings on the usefulness of preoperative TMI as a prognostic marker, further expanding knowledge about its accuracy by comparing and combining it with established prognostic factors, including CEA and CA 19-9.

The contemporary demographic development of Bosnia and Herzegovina is a very active topic in academic, but also in wider political and public discourses, particularly in the context of increased depopulation trends. Distinctly negative processes in the natural change and net migration are the result of post-war and transitional circumstances, as well as the socio-economic status of the country. Demographic disparities conditioned by a complex social background (economic, social, political, cultural and environmental factors) are often the subject of geographic research in this area, however, few studies have resulted in a comprehensive demographic categorization of municipalities and cities in Bosnia and Herzegovina, which would be the first step in detection precise causes of demographic regression. Demographic categorization of municipalities on the basis of as many available demographic indicators as possible is a useful instrument in planning, through which concrete revitalization measures can be created primarily aimed at reducing polarization effects in development and depopulation of continuously deprived regions. This study used demographic data from the last 2013 population census, as well as those from more recent publications of national and entity statistical agencies. Special focus is placed on the index of total population change, population density, vital index, ageing coefficient and share of highly educated population. These indicators were analysed from the aspect of regional disparities, whereby special categories of municipalities and cities were created for each of them, in relation to how favourable is local demographic situation. In the second phase, their multi-criteria data integration was carried out, which more clearly indicate the general level of demographic development of individual municipalities/cities.

Remote sensing plays a vital role in analyzing urban changes. In this regard, various datasets collected from satellites today serve as a foundation for decision-makers and urban planners. This study compares the Normalized Difference Vegetation Index (NDVI) and the Normalized Difference Built-up Index (NDBI) as indicators for the creation of surface heat islands. Using Landsat 8 OLI/TIRS C2 L2 images, spatial correlations between land surface temperature (LST) were examined for August 2013, 2019 and 2023. Urban heat islands (UHI) are a contemporary phenomenon and increasingly common in large urban areas compared to surrounding, less populated areas. With the advancement in remote sensing, it is possible to adequately determine the spatial differentiation and prevalence of urban heat islands (UHI). The study is based on Landsat 8 satellite image sets for the Sarajevo basin in August 2013, 2019 and 2023, which were used to analyze LST, NDVI, and NDBI indices. This work indicates a relationship between LST and NDVI but varies depending on the analyzed year. Normalized Difference Built-up Index (NDBI) serves as a suitable indicator for surface UHI effects and can be used as an indicator to assess its spatial distribution within a larger urban environment.

The global trend of incorporating students with disabilities into mainstream education is on the rise, a phenomenon observed in countries like Macedonia and Bosnia and Herzegovina. However, the attitudes of parents with typically developing children play a pivotal role in shaping the educational journey of students with special needs within regular school systems. This study aims to delve into the level of sensitization among parents of typically developing students concerning their peers with diverse developmental disabilities in Macedonia and Bosnia and Herzegovina. Data for this investigation were collected through a survey comprising 10 questions, each offering 3/4 possible responses. The sample size includes 90 parents of typically developing students attending regular schools across North Macedonia and Bosnia and Herzegovina. Thematic analysis of survey results unveils challenges and barriers in the inclusive education process, shedding light on parental sensitization. This exploration identifies specific issues and proposes potential solutions to enhance the inclusivity of the education system. The identified issues emphasize the necessity for targeted interventions and proactive measures to raise awareness among parents, fostering a more supportive and inclusive educational environment. By suggesting plausible solutions, this study contributes to the ongoing discourse on inclusive education, serving as a foundation for further research and practical initiatives.

Background: Prior to 2012, the mesentery was perceived as a fragmented structure, lacking distinct functional and anatomical characteristics, and was merely considered part of other digestive organs. Dr. J. Calvin Coffey's in 2012 in his study redefined the mesentery as a distinct organ with a clearly defined anatomical and histological structure, although its specific function remains under investigation. The continuous structure and unique tissue properties of the mesentery classify it as the 78th independent organ in the human body. Insights into mesenteric adipose tissue have enhanced our understanding of normal metabolic processes and disease etiology, impacting health significantly. Experimental and clinical research highlights the vital roles of visceral adipose tissue, influencing neighboring organ function. The interaction within the brain-gut-liver axis is illuminated by the newfound functions of mesenteric adipose tissue, emphasizing its independent organ status. Objective: This study aims to evaluate the latest findings on the structure and function of the mesentery, focusing on visceral-mesenteric adipose tissue, and assess its role as a new organ in the brain-gut-liver axis. Methods: A comprehensive analysis of clinical and experimental studies on the mesentery's structure and function was conducted, focusing on recent discoveries regarding mesenteric adipose tissue and its role in the brain-gut-liver axis. Results and Discussion: Recent research has revealed the mesentery's unique functions, particularly in mesenteric adipose tissue. Mesenteric adipose tissue plays a crucial role in metabolic functions and influences disease onset. It acts as a vital link in the brain-gut-liver axis, directly influencing hepatic metabolism and disorders such as metabolic syndrome. Conclusion: Scientific evidence confirms the mesentery's anatomical and functional specificities, solidifying its status as the 78th independent organ in the human body. It serves as a crucial link in the brain-mesentery-small intestine-liver axis, impacting health and disease. Ongoing research holds promise for advancing our understanding of pathophysiological mechanisms and treatment approaches for metabolic syndrome and other chronic diseases.
