This study aims to do a morphological and biochemical characterization of selected wild hop populations from the Banja Luka region, as plant material with potential value for introduction into plant selection. Female inflorescences (cones) from seven populations (DKH3, DKH5, DKH6, DKH8, DKH9, DKH10, and DKH11) were sampled in 2018 and 2019. Hop cones were collected in October 2018 and 2019 for morphological characterization, when 50 cones per population were analyzed, and also the cones were collected in mid-September in 2019 for biochemical characterization. Morphological parameters were carried out for: cone length (cm), number of nodes per cone spindle, cone density, and number of seeds per cone, all important agronomic characters in hop production. Also, 27 components of essential oil and 6 components of hop resins were analyzed. Statistical analysis of morphological characteristics was performed by factorial analysis of variance (year × population), and the significance of individual differences was determined by LSD test. The grouping of examined hop populations according to the manifested morphological characteristics was performed by cluster analysis. Statistical analysis for biochemical characteristics was performed by analysis of variance, and the significance of the differences was tested by Tukey’s statistical test. In order to determine similarities between different population multivariant statistical method Principal component analysis (PCA) was applied. According to morphological and biochemical analysis, DKH6 hop population is singled out as the most valuable for hop breeding.

OBJECTIVE Tumors of the brain and spine make up about 20% of all childhood cancers; they are the second most common form of childhood cancer after leukemia. Brain tumors are the most common solid tumor in children. Symptoms depend on a variety of factors, including location of the tumor, age of child, and rate of tumor growth. The aim of study was to present our experience with the diagnosis and treatment of brain tumors in children. PATIENTS AND METHODS The aim of this study is to analyze clinicopathological characteristics, treatments, complications, and outcomes in children with brain tumors. This study is a retrospective analysis of 27 consecutive patients younger than 16 years and hospitalized for surgical treatment of brain tumors. Intracranial hypertension, neurological status, radiological computerized tomography (CT) or magnetic resonance imaging (MRI) findings, tumor localization, type of resection, hydrocephalus treatment, histopathology, complications, and outcome were analyzed. RESULTS Twenty-seven surgeries were performed in patients for brain tumors. There were 9 females and 18 males. The average patient age was 7.8 years. There were 11 (40%) children with astrocytoma; of these, there were 9 (82%) pilocytic astrocytomas and 2 (18%) ordinary histopathological subtypes of high-grade tumors. CONCLUSION As with any cancer, prognosis and long-term survival vary greatly from child to child. Prompt medical attention and aggressive therapy are important for the best prognosis. Continuous follow-up care is essential for a child diagnosed with a brain tumor.

Sport is one of the world’s most important resources and an indispensable part of international culture. Men and women participate in most sports from football, basketball, boxing to extreme sports. The aim of this paper is to research gender equality in many aspects of sport, from equal pay, sponsorship agreements, to scholarships as state support to talented athletes. The paper presents a theoretical framework for defining sport and its significance. The media attitude towards sports is discussed and the symbiosis relationship between sports and the media is emphasized. The focus of the paper is on women in sports and their progress towards gender equality in all sports activities from participation, coaching positions to management. An analysis of the results of the survey was done. The survey was conducted on a representative sample of 201 respondents. The questionnaire was on sports monitoring and key issues on equality in the choice of sports, media attention, equal pay and sponsorship agreements as well as on prejudice against female athletes and career duration and monitoring of women’s football given the growing popularity of the sport.

Perennial plant Mentha pulegium L. (pennyroyal, Lamiaceae) can be found in Europe and Mediterranean. In areas where it thrives, M. pulegium is used in nutrition and as medicinal plant. Essential oil of M. pulegium is also a frequent constituent of foods and fragrances, because of mint‐like odor. Regarding the use of M. pulegium in traditional medicine and nutrition, as well as fact that essential oils are potential sources of bioactive components, this study was conducted to examine the chemical composition of essential oil of M. pulegium wild growing in Bosnia and Herzegovina and its biological activity. The chemical profile testing was made using GC/MS and GC/FID technique. Potential of cholinesterase inhibition was tested by Ellman's assay. The antioxidant activity was tested by DPPH and FRAP assay. The dominant components in analyzed oil were pulegone 54.4 %, p‐menthone 14.0 % and piperitenone 12.8 %. Good antioxidant activity and moderate cholinesterase inhibition potential of tested essential oil indicates to possibility of its use in treatment of diseases related to free radicals, Alzheimer disease and as lipid protecting antioxidant.

ABSTRACT Purpose : To investigate state- and trait-like risk factors leading to childhood eye injuries controlling for the between-subject difference. This study measured socioeconomic, environmental, behavioral, and injury event characteristics to identify eye injury protective and risk factors. Methods : A retrospective case-crossover study including patients aged 0–18 years old (y.o.) with severe eye trauma treated at the Canton Hospital Zenica between 2011 and 2017 was conducted. One case time point was at the time of injury, and two control time points 1 month before the injury and a month before the survey. Results : Of 36 patients meeting the criteria, four were excluded, resulting in 32 cases and 64 controls. The mean age was 10.79 in males (77.8%) and 11 y.o. in females (22.2%). In univariate GEE logistic regression unusual activity had odds of 17.25 (95%CI = 6.97, 42.70), working/chores vs.running activity odds of 6.60 (95%CI = 1.71, 25.46), very active level vs.an intermediate child activity level odds of 5.26 (1/0.19, 95%CI = 1.75, 16.67) no supervision odds of 2.63 (1/0.38, 95%CI = 1.45, 4.76) and less than 7 hours of sleep odds of 4.69 (95%CI = 1.06, 20.77) of sustaining an eye injury. Using the quasi-likelihood approach and QICu as an indicator, the best model yielded odds of getting eye injured = 0.59 + 19.35*engaging in unusual activity+0.21*supervised by an adult person+0.84*playing+3.04*working within the households+0.22*other activity. Conclusions : Giving the best model to predict injuries, the combined strategies of teaching, modifying the environment, and the watchful supervision present a preventive triad that needs to be further explored and encouraged in practice.

Introduction: The incidence of N1 and N2 metastases in relation to the presence of peritumoral lymphovascular infiltration and tumor grade in bronchial carcinoma still remain insufficiently researched areas that could provide valuable guidance. Several studies have shown a statistically significant difference in the occurrence of N1 and N2 metastases in relation to the type and size of the bronchial carcinoma. The relationship between the occurrence of N1 and N2 metastases and the degree of immaturity of the tumor in the bronchial carcinoma remains insufficiently documented. Patients and methods: This study included 331 patients of all ages, both men and women, diagnosed with bronchial carcinoma using various diagnostic procedures. In these patients, surgical treatment was indicated and the anatomical resection was performed. Result: A total of 331 patients were included in the study and N1 metastases were present in 39.88% of cases, while N2 metastases were present in 4.53% of cases with bronchial carcinoma. Peritumoral lymphovascular invasion was present in 37.55% of cases (86 out of 229 patients) with N0 disease, in 55.89% of cases (128 out of 229 patients) with N1 disease, and in 6.55% of cases (15 out of 229 patients) with confirmed N2 disease. Conclusion: The presence of the peritumoral lymphovascular invasion is more often accompanied by metastases in corresponding regional lymph nodes. By calculating the total relative risk, there is almost a 30-fold higher risk of developing metastases in N1 and N2 lymph nodes in the presence of peritumoral lymphovascular invasion.

This paper is part of broader research aimed at determining the relationship between energy performance and energy costs as a part of the operational and life cycle costs in school buildings in the Federation of Bosnia and Herzegovina (FBiH), as exceptionally important social and public buildings. The research was conducted by statistical analysis of data collected from documents of detailed energy audits (DEA) for 185 school buildings in FBiH in relation to construction periods. The paper analyzes the characteristics of buildings such as construction period, building envelope characteristics, climatic conditions, efficiency of installed space heating system, number of users and heating mode. The aim of this research was to determine the energy performance for the existing state and to compare them with the allowable values in accordance with the applicable legal regulations. There is a performance gap between predicted (calculated) and measured (actual) delivered energy for space heating. This research shows poor energy performance and provides a basis for developing strategies and plans to improve energy efficiency. The results of the energy performance of school buildings in the FBiH are the first step towards the development of a model for predicting energy costs.
