Previous transcriptome-wide association studies (TWAS) have identified breast cancer risk genes by integrating data from expression quantitative loci and genome-wide association studies (GWAS), but analyses of breast cancer subtype-specific associations have been limited. In this study, we conducted a TWAS using gene expression data from GTEx and summary statistics from the hitherto largest GWAS meta-analysis conducted for breast cancer overall, and by estrogen receptor subtypes (ER+ and ER−). We further compared associations with ER+ and ER− subtypes, using a case-only TWAS approach. We also conducted multigene conditional analyses in regions with multiple TWAS associations. Two genes, STXBP4 and HIST2H2BA, were specifically associated with ER+ but not with ER− breast cancer. We further identified 30 TWAS-significant genes associated with overall breast cancer risk, including four that were not identified in previous studies. Conditional analyses identified single independent breast-cancer gene in three of six regions harboring multiple TWAS-significant genes. Our study provides new information on breast cancer genetics and biology, particularly about genomic differences between ER+ and ER− breast cancer.

Although around the globe numerous studies have been conducted on the nutritional composition of blueberry/bilberry and its effect on human health, very little is known about the fruit in Bosnia and Herzegovina. This is the first report regarding the physical and chemical characteristics of the cultivated highbush blueberry and bilberry harvested in the same climatic conditions in Bosnia and Herzegovina. In this paper we present the physical weight and chemical soluble solids content, total sugars, titratable acidity, pH, and total phenols properties of the wild bilberry Vaccinium myrtillus L. and cultivated highbush-'Earliblue', 'Bluegold', 'Bluecrop', 'Goldtraube'-blueberry Vaccinium corymbosum L. . Among the highbush blueberry cultivars, 'Bluegold' 2.07-2.11 g and 'Bluecrop' 2.08-2.11 g had the highest weight. 'Bluecrop' had the highest soluble solids content 13.3-13.7 °Brix and total sugars 9.73%?9.94% , but the lowest content of titratable acidity 0.70-0.72 g/100 g , which was highest in 'Goldtraube' 0.92-0.93 g/100 g . This cultivar also had the highest content of total phenols 289-309 mg gallic acid equivalent/100 g of fresh weight . In the case of wild bilberry, the following values were obtained: average weight 0.28-0.32 g, soluble solids content 11.1-11.3 °Brix, total sugars 7.23%-7.37%, titratable acidity 0.99%-1.02%, and total phenols 431-455 mg/100 g. Blueberry and wild bilberry also had a fairly uniform pH 3.2-3.6 . All samples had a valuable composition and so it is advisory to expand their production in Bosnia and Herzegovina in order to increase their consumption.

The steady increase in electricity demand has led to more installed generation capacity in wind farms, which, due to the stochastic nature of their production, may have characteristic and non-standard responses to some occurrences in the grid. The power output from the wind farm changes constantly, depending on the wind speed, so the impact of the network on the wind farm will inversely vary depending on the moment of the short circuit and the wind farm operating mode, since the values of currents and voltages in these fault systems depend on the power flows. Although wind power is known to contribute to the short circuit current / power at the point of its connection, this paper focuses on the response of the wind farm to short circuits in the network and the impact of these phenomena on the grid-wind relation. The aim of the paper is to determine the worst type of short circuit for wind turbine operation in the distribution system.

Breast cancer is one of the major causes of mortality in women worldwide. The most aggressive breast cancer subtypes are human epidermal growth factor receptor-positive (HER2+) and triple-negative breast cancers. Therapies targeting HER2 receptors have significantly improved HER2+ breast cancer patient outcomes. However, several recent studies have pointed out the deficiency of existing treatment protocols in combatting disease relapse and improving response rates to treatment. Overriding the inherent actions of the immune system to detect and annihilate cancer via the immune checkpoint pathways is one of the important hallmarks of cancer. Thus, restoration of these pathways by various means of immunomodulation has shown beneficial effects in the management of various types of cancers, including breast. We herein review the recent progress in the management of HER2+ breast cancer via HER2-targeted therapies, and its association with the programmed death receptor-1 (PD-1)/programmed death ligand-1 (PD-L1) axis. In order to link research in the areas of medicine and mathematics and point out specific opportunities for providing efficient theoretical analysis related to HER2+ breast cancer management, we also review mathematical models pertaining to the dynamics of HER2+ breast cancer and immune checkpoint inhibitors.

Before even opening the book, Democracy by Decree: Prospects and Limits of Imposed Consociational Democracy in Bosnia and Herzegovina captures the reader’s attention with its intriguing and provocative title. But what author Adis Merdzanovic delivers in its pages is equally engaging. Merdzanovic illustrates how the consociational power-sharing arrangements in Bosnia and Herzegovina were imposed by the international community following the wars in the 1990s, rather than genuinely initiated from inside a country, and have, perhaps unsurprisingly, largely failed.

The Internet of Things (IoT) is a concept of the modern, interconnected world. Over 50 billion devices, globally-connected, make up the largest network that is stepping towards the fourth industrial revolution, and which will significantly change the system of values and business systems. In the world of heterogeneous communication technologies, choosing the optimal one is a challenge for system architects, which is not an easy task often. The paper presents a comparative analysis of widespread communication technologies in the domain of IoT, and the conclusions presented based on the performed analysis, provide a better insight into the choice of the optimal solution depending on the problem domain and therefore better quality of solutions based on the concept of IoT.

Temperature-stable dissolving film eliminates cold-chain storage and successfully immunizes mice sublingually and buccally. A novel, thin-film platform that preserves live viruses, bacteria, antibodies, and enzymes without refrigeration for extended periods of time is described. Studies with recombinant adenovirus in an optimized formulation that supports recovery of live virus through 16 freeze-thaw cycles revealed that production of an amorphous solid with a glass transition above room temperature and nitrogen-hydrogen bonding between virus and film components are critical determinants of stability. Administration of live influenza virus in the optimized film by the sublingual and buccal routes induced antibody-mediated immune responses as good as or better than those achieved by intramuscular injection. This work introduces the possibility of improving global access to a variety of medicines by offering a technology capable of reducing costs of production, distribution, and supply chain maintenance.

Introduction: Ramadan is the holy month of Muslims including fasting sometimes more than 20 hours. Even diabetes patients can be exempted from fasting it has been shown that almost 80% of diabetes type 2 patients intend and do fasting. To avoid acute complications during fasting, different recommendations on diabetes management are available. Considering the fact that there are more than 226 thousand diabetics in Bosnia and Herzegovina, it is important to provide structured support and healthcare service to those who are practicing fast during Ramadan. Aim: To evaluate knowledge, practice and attitudes of physicians treating diabetes (diabetologists and endocrinologists) in Bosnia and Herzegovina regarding management of diabetes in fasting patients during Ramadan. Methods: A 32 questions survey has been developed, validated and disseminated to the 27 specialists treating diabetes in Bosnia and Herzegovina through online form examining demographic characteristics, current practices and attitudes and knowledge on diabetes management during Ramadan. Results: All surveyed physicians deal with patients who are fasting during Ramadan. The majority of surveyed physicians 23 (85,2%) proactively initiate a discussion about planned fasting. More than 63,0% are following their experience and only 18,5% ADA/EASD guidelines on diabetes management during Ramadan. There are no significant differences between gender of the physicians, place of work and specialization when it comes to specific knowledge related to treatment guidelines, but some differences are observed. Conclusion: Although overall physicians` knowledge of diabetes management during Ramadan is satisfying there is opportunity in additional specialized education and measures introduction into the practice in order to improve treatment outcomes and standards of care.

This paper presents a data visualization method in 3D space that includes actual positions, volumes and space relations of the chunks of data that are being visualized. Data that is being visualized is real-time information provided by the smart warehouse management system about packages distributed on pallet places within a warehouse. Three different visualizations are shown: qualitative, quantitative and cumulative. The method is graded for the time needed to determine the location of all pallet places that fulfill searched criteria and getting the exact value of searched information for each pallet place. Challenges in presenting this data and interacting with resulting visualizations are discussed. It is concluded that showing actual positions of chunks of data greatly increases the speed of acquiring searched values and positions at the same time for outliers but has issues with clusters and multiple types of queried data.
