This biographical note details Anna Bayerová's (1853-1924) activities as the first female Austro-Hungarian health officer in 1878 to1918 occupied Bosnia and Herzegovina (BH). Anna Bayerová is known as a heroine of Czech feminism and the 'first Czech female physician', though she only practised in the Czech lands from 1913 to 1916. In 1891, Bayerová was enrolled as the first Austro-Hungarian female health officer and assigned to treat Muslim women in the district of Tuzla, Bosnia. She pursued this mission for the first three months of 1892, had herself transferred to Sarajevo in the summer, and soon thereafter quitted the service. Her biographers point to a series of political and personal motivations to abandon her mission in Bosnia, which, from the viewpoint of Czech feminists, included fulfilling her professional duties in an exemplary way. She spent most of her professional life as a physician in Switzerland and did not request Austrian recognition of her medical degree until 1913. Bayerová died in Prague in 1924. Conclusion. Bayerová, partly for political reasons and partly due to her panic-fuelled fear of catching tuberculosis, quitted her role as the first Austro-Hungarian female health officer in BH soon after her arrival in 1892.

Apoptosis, as a well-studied process of a programmed cell death, is essential for the maintenance of cell homeostasis and integrity of organisms. This process occurs normally during development and aging and it is a balance of the sustainability of the tissue cell population. In addition, apoptosis also occurs as a defensive mechanism such as an immune response or after cell damage as a consequence of a pathological condition or the action of harmful agents. Apoptotic activation tends to be less responsive with aging, causing accumulation of non-functional cells and pathological changes such are degenerative diseases or tumor transformation. This overview aims to provide summarized facts about different approaches of apoptosis research, targeting and regulation in tumors especially in leukemic cells as a way of pharmacological manipulation with a potential therapeutic benefit.

Taxus baccata L., yew, is dioecious, small to medium-sized evergreen tree, native to Europe, Africa and Asia, but it is cultivated worldwide because of its ornamental features. It is long known that all parts of yew (except for aril) are toxic, due to the alkaloid taxine. Nevertheless, some parts of yew tree can be used to treat cancer and as antimicrobial agents. Unlike its antibacterial properties, antifungal activity of T. baccata is poorly investigated. In this research, antifungal activity of yew methanolic and aqueous extracts was tested against Candida albicans ATCC 10231, Aspergillus brasiliensis ATCC 16404, and Ascosphaera apis MUCL 30769, through the agar well diffusion method. Leaves, bark and reproductive structures extracts were prepared separately for male and female plants. Unlike the aqueous, methanolic extracts caused variable degree of fungal growth inhibition. The strongest inhibition was observed in the activity of the aril extract against A. brasiliensis and C. albicans, with the activity of the male bark extract against A. apis following close. Considering the emerging multidrug resistance in C. albicans, an interesting finding is the inhibition of this species by all tested methanolic extracts, which is significantly stronger in comparison to the inhibition by standard antimycotic solution. According to the available data, male reproductive structures of this species were not tested earlier for their antifungal activity, and our study showed high level of antifungal activity of methanolic microstrobili extract.           

Humans are exposed to a cocktail of heavy metal toxicants in the environment. Though heavy metals are detrimental, there is a lack of information on the toxicity of mixtures. In this study, two common heavy metals, lead and cadmium, were introduced individually and as mixtures to HL-60 and JURKAT cell lines for 24 hours. The study established that exposures to these two heavy metals induced cytotoxic and genotoxic effects on both cell lines. Also, cadmium exhibited a higher cytotoxic and genotoxic potential than lead. The cytotoxicity data of single metals were used to determine the mixtures interaction profile by using the effect additivity method. Metal mixtures showed synergistic effect in HL-60 cells and antagonistic effect in JURKAT cells, compared to individual metals. The combined effects should be considered in the risk assessment of heavy metal co-exposure and potency.

Recent studies investigating the evolution of genome size diversity in ferns have shown that they have a distinctive genome profile compared with other land plants. Ferns are typically characterized by possessing medium‐sized genomes, although a few lineages have evolved very large genomes. Ferns are different from other vascular plant lineages as they are the only group to show evidence for a correlation between genome size and chromosome number. In this study, we aim to explore whether the evolution of fern genome sizes is not only shaped by chromosome number changes arising from polyploidy but also by constraints on the average amount of DNA per chromosome. We selected the genus Asplenium L. as a model genus to study the question because of the unique combination of a highly conserved base chromosome number and a high frequency of polyploidy. New genome size data for Asplenium taxa were combined with existing data and analyzed within a phylogenetic framework. Genome size varied substantially between diploid species, resulting in overlapping genome sizes among diploid and tetraploid spleenworts. The observed additive pattern indicates the absence of genome downsizing following polyploidy. The genome size of diploids varied non‐randomly and we found evidence for clade‐specific trends towards larger or smaller genomes. The 578‐fold range of fern genome sizes have arisen not only from repeated cycles of polyploidy but also through clade‐specific constraints governing accumulation and/or elimination of DNA.

Next Generation Sequencing (NGS) has become powerful tool in molecular oncology. It allows multiparallel targeted sequencing that enables comprehensive assessment of tumor heterogeneity. Detection of mutations in colorectal cancer (CRC) and non-small cell lung cancer (NSCLC) defines patients diagnosis, therapy and prognosis. Multiple genes, their somatic mutations to be precise, carry different degrees of importance for any of these stages. Ion AmpliSeq™ Colon and Lung Cancer Research Panel v2, which was used in this study, allows detection of hotspot mutations on 22 genes in a single reaction. Droplet digital PCR (ddPCR) has a unique advantage in low frequency mutation detection and it has been used as a validation method for mutations that were detected with NGS. It has high sensitivity and enables accurate detection of mutant allele in a background of abundant wild type alleles. For this study 35 samples of CRC and NSCLC were sequenced and same samples were analysed on ddPCR for KRAS, NRAS, EGFR and BRAF genes. All processed samples were successfully sequenced and had average base coverage >500X. NGS sequencing proved itself to be cost effective, has shorter turnaround time and is highly sensitive. Out of 35 samples, 25 had genetic alterations, while 10 samples are reported as wild type but were still tested on ddPCR as controls. In three samples low frequency somatic mutations were detected by NGS and verified using ddPCR, which leads us to conclusion that ddPCR is a good tool for verification of somatic mutations in CRC and NSCLC.

This study was designed on the analysis of the mtDNA polymorphisms in three ethnic populations of Tuzla Canton of Bosnia and Herzegovina (Bosniaks, Croats and Serbs). The main aim of this study was to analyze the influences of the maternal gene flow on the genetic profile of the analyzed populations. The analysis of mtDNA variation based on relevant restriction fragment length polymorphisms (RFLP) in combination with HVSI variations of the control region (for detection of subhaplogroups of the haplogroup U) enabled the identification of the typical of the Western-Eurasian haplogroups (H, I, J, T, W, U, HV, HVO, K, V, and X), African/Near East lineages N1a and Asian haplogroup M. Our results suggest that mitochondrial gene pool of the three main ethnic groups of Tuzla region was shaped by influences of early and late migration routes which marked the settlement process of the Balkans. The effects of different migration directions are illustrated by the distribution of important indicators of the Late Glacial expansion (U5a), postglacial re-colonisation of Europe from glacial refuges of southwestern European (H, V, U5b1), central-eastern European Plain (U4), Italian Peninsula (U5b3) and neolithic expansion (U3, N1a, J and T). Our data can indicate a common genetic history, origin, as well as a similar contribution of the parental and maternal gene flow on genetic structure of the three main ethnic populations of modern Bosnia and Herzegovina.

It is widely accepted that understanding the heterogeneity of a population is important in assessment of the vulnerability of a conservation unit (Frankham et al., 2002). Standard measures such as estimation of heterozygosity, deviations from Hardy–Weinberg equilibrium, effective population size, inbreeding coefficients are widely used. Minor, but very important elements of these measures are allelic diversity, effective number of alleles and allelic richness which characterize the extent of genetic diversity. Allelic diversity (An) represents an average number of alleles per locus determined by direct count. When more than one locus is considered, it is calculated as a number of alleles averaged over loci expressed as k/l where k is the total number of alleles determined at all the observed loci and l is the number of loci (Frankham et al., 2002). The effective number of alleles (Ae) is a measure that shows the number of alleles required to ensure the same level of heterozygosity under the assumption of balanced allele frequency and low influence of rare alleles. It is expressed as 1/Σpi 2

The purpose of this study was to compare unenhanced MR angiography with contrast-enhanced MR angiography and visualisation of renal arteries with its segment branches using both techniques. We performed renal MRA on 22 patients using a 1.5T MRI unit. For renal MRA, a three dimensional balanced type steady-state free precession (SSFP) sequence (Time-SLIP, Canon) was used with respiratory gating and conventional CE-MRA sequnce (upisati tačan naziv). For analysis, two radiologists independently evaluated the visual quality of the axial images and axial maximum intensity projection images (MIP) of Time SLIP and CE MRA. Visualisation of aorta and main stem of the renal arteries were satisfactory on both techniques, and there was no statistically significant difference. The score of segmental renal artery appeared superior with Time-SLIP and showed a statistically significant difference (P<0.05). Visualisation of segmental renal arteries, interlobar renal arteries and kidneys parenchyma was significantly superiorwith Time-SLIP technique. We compared visualisation of renal arteries and its branches using unenhanced MRA, Time-SLIP, in comparison with contrast-enhanced MRA. Although it is slightly time-consuming and its clinical utility is necessary to further investigate, unenhanced MRA provides superior visualization of peripheral branches even in this study. Further improvement of the technique would make it even more sensitive in detecting small vessel abnormalities and it is promising for clinical use.

INTRODUCTION: Diseases of the locomotor system or musculoskeletal disease are on the rise, mainly due to the ageing of the population but also due to lifestyle changes. Those are the main cause of chronic pain and disability in the modern world. Thanks to the achievements of modern medicine, in patients with advanced osteoarthritis of the hip or knee it is possible to replace the diseased joint with an endoprosthesis, with very good long-term results related to pain reduction and function improvement. The aim of this study is to examine are there any differences in the quality of people's life before and after implantation of total knee endoprosthesis. RESPONDENTS AND RESEARCH METHODS: There were 30 subjects of both genders with knee joint disease enrolled in the study, who were treated with the surgical course at the Orthopedics clinic and the traumatology of the UKCS by implanting a total endoprosthesis, from the beginning of April until the end of October 2018. As an instruments of this research are used standardized SF-36 questionnaire for assessing the quality of life and overall health status and a modified questionnaire on the socio-demographic characteristics of the respondents. RESULTS: Patients after implantation of total knee endoprosthesis have a better quality of life, i.e. statistical significance at physical function level (P = 0.0001), role limits due to physical problems (P = 0.0001), social functions (p = 0.0001), energy or vitality (P = 0.0001), pain (p = 0.0001), limitations of the role due to emotional problems (P = 0.0001), and emotional prosperity (P = 0.0001) and general health (P = 0.004). CONCLUSIONS: The quality of life of patients was worse before the period after the total knee endoprosthesis, where statistically significant improvement was demonstrated.

This work follows the recent discovery of a zinc-bearing Egyptian blue (EB) pigment widely used for the production of the early medieval mural paintings cycle in Santa Maria foris portas Church at Castelseprio (Lombardy Region, Italy). The inclusion of zinc in the synthesis of EB has been studied for the first time trying to evaluate whether its addition could be casual or deliberate. Historical reconstructions of the pigment have been carried out with a special focus on the use of zinc besides copper, using the different production methods. The influence of zinc on the pigment’s NIR photoluminescence and VIS-NIR reflectance has been characterized using FORS spectroscopy, X-ray diffraction, optical microscopy, and scanning electron microscopy-energy dispersive X-ray spectroscopy. A comparison of the production methods including salt-flux, solid-state, and Zn-rich syntheses showed that the solid-state synthesis results in particularly efficient NIR photoluminescence and VIS-NIR reflectance. Modern replicas were compared with an ancient sample in order to understand the zinc environment inside the structure of the Zn-enriched EB. Zn was found to be concentrated in a glass-based matrix surrounding cuprorivaite crystals, the main mineral associated with the EB pigment, and not included in a hypothetical Zn-doped cuprorivaite with formula CaCu1−xZnxSi4O10. The Zn-rich synthesis opens up the possibility of producing EB from brass and demonstrates that EB used in Castelseprio’s mural paintings could have been produced in this way. The relationship between the microstructure and the NIR photoluminescence of cuprorivaite-like pigments is of interest also for applications in modern and future technologies.

Currently, blockchain technology has been widely used due to its support of transaction trust and security in next generation society. Using Internet of Things (IoT) to mine makes blockchain more ubiquitous and decentralized, which has become a main development trend of blockchain. However, the limited resources of existing IoT cannot satisfy the high requirements of on-demand energy consumption in the mining process through a decentralized way. To address this, we propose a decentralized on-demand energy supply approach based on microgrids to provide decentralized on-demand energy for mining in IoT devices. First, energy supply architecture is proposed to satisfy different energy demands of miners in response to different consensus protocols. Then, we formulate the energy allocation as a Stackelberg game and adapt backward induction to achieve an optimal profit strategy for both microgrids and miners in IoT. The simulation results show the fairness and incentive of the proposed approach.
