SuMMAry – Introduction. Ocular microvascular changes can be related to kidney deterioration in chronic kidney disease (CKd). We aimed to identify the association between retino-choroidal parameters and kidney deterioration in diabetics and non-diabetics. Methods. The study group consisted of CKd patients (cross-sectional study) with arterial hypertension with different stages of CKd. Complete eye examination was completed with optical coherence tomography angiography (OCtA) scans of the macular region. According to the value of glomerular filtration rate (gfr) and albuminuria, patients were divided into groups: low gfr (<60ml/min) and high gfr (>60ml/min) and CKd patients without albuminuria and CKd with micro or macroalbuminuria. Results. One hundred and six eyes of 106 chronic kidney disease patients were evaluated. The mean retinal thickness in gfr <60 ml/min group was 275,73±9,65 micron (µ), whereas in a gfr >60 ml/min group was 274,36±10,77 µ. OCtA showed lower deep vascular density (dvd) in CKd with albuminuria versus CKd without albuminuria group (p < 0.001). Albuminuria was inversely related to choroidal and retinal thickness measures of superficial (Svd) and dvd. Conclusions. CKd is associated with retinal diluting and decreasing kidney function with reduction of retinal and choroidal vascular density.

It is shown that locally asymptotically stable equilibria of planar cooperative or competitive maps have basin of attraction \begin{document}$ \mathcal{B} $\end{document} with relatively simple geometry: the boundary of each component of \begin{document}$ \mathcal{B} $\end{document} consists of the union of two unordered curves, and the components of \begin{document}$ \mathcal{B} $\end{document} are not comparable as sets. The boundary curves are Lipschitz if the map is of class \begin{document}$ C^1 $\end{document} . Further, if a periodic point is in \begin{document}$ \partial \mathcal{B} $\end{document} , then \begin{document}$ \partial\mathcal{B} $\end{document} is tangential to the line through the point with direction given by the eigenvector associated with the smaller characteristic value of the map at the point. Examples are given.

ISSN 2620-0406 Citation: Šikman, M. M, & Grujić, M. (2021). Relationship of AntiMoney Laundering Index with GDP, financial market development, and Human Development Index. NBP. Nauka, bezbednost, policija, 26(1), 21–33. doi:10.5937/nabepo26-29725 Abstract: Money laundering has a direct impact, among other things, on the economic development of a country. The aim of this research is to determine the correlation between money laundering and economic development expressed through GDP, as well as between financial market development (FDI) and the Human Development Index (HDI). The results of the research show that there was a significant relationship between the observed variables, i.e. that there is a relation of the Anti-Money Laundering Index (AMLI) on GDP, financial market development and the HDI. Namely, given that medium-strong links between the observed variables have been established, it can be claimed that there is reason to believe that “copying the behaviour” of a certain country in the fight against money laundering can further develop the financial market, influence human development or an increase in GDP per capita. In particular, a decrease in the AMLI was expected to increase the FDI (R2 = 0.2601). A decrease in the AMLI was expected to increase the HDI (R2 = 0.5747). In that way, financial institutions are directly affected, which negatively relates to economic and political stability.

This paper presents an empirical verification of the effectiveness and usefulness of investment diversification using the main stock exchange indices and Bitcoin. The objective is to determine the effects applying the Markowitz portfolio optimization theory, i.e., the advantages of applying the modern portfolio theory for institutional investors. The research offers an answer to the following question: what are the advantages and disadvantages of using Bitcoin in portfolio optimization? The paper contributes to the representation of the reach and limitations of the modern portfolio theory for institutional investors. The conclusion is that rational behaviour of institutional investors requires consideration of portfolio optimization using the Markowitz model, because it is possible to create portfolios which, on the basis of historical returns, provide desired returns alongside certain risks. The methodology includes the analysis of high frequency data, i.e., daily trading data were used. The results indicate that the use of the Markowitz portfolio selection method, with all its limitations, is desirable, possible and applicable, but that it entails serious flaws in the sense of neglecting transaction costs, foreign exchange differences and the real value in the stock market. The results of the research show that Bitcoin is a good source of diversification in a portfolio that contains traditional financial instruments both for the risk-averse investor as well as for those investors who have a greater appetite for risk. The conclusion is that rational behavior of institutional investors requires consideration of investing in Bitcoin using the Markowitz model. However, given the high degree of volatility, investors should be very careful when making decisions about including Bitcoin in the portfolio.

Cardiovascular diseases are known to be treated with anticoagulants lifelong. Warfarin is one of the most commonly used medications for anticoagulation despite causing serious side effects in some patients. Different single nucleotide polymorphisms (SNPs) that have a role in the cytochrome P450 system can also affect the metabolism, as well as dosing, of warfarin. The purpose of this review is to look into the prevalence of this SNP in the past research and screen for possible correlations with age, place of origin, family history of cardiovascular and cerebrovascular diseases, or other medical conditions possibly present in various populations. In total, 20 scientific articles falling under the inclusion criteria were reviewed and found usable, and the rest of the cases will be highly beneficial in the upcoming years to determine the role of the recently discovered CYP4F2 rs2108622 variant, as well as the previously known CYP2C9 and VKORC1 SNPs, in the variance of warfarin dose requirement. These findings may also point researchers in the right direction for qualifying and validating these genetic variants for use as GBs (genomic biomarkers) in the clinical and medical practice of treatment with warfarin.

There is no doubt that examples from folklore have useful, functional and aesthetic value in music teaching, and that it is preferable to use them for educational purposes. Selected examples of folk songs from Montenegro have their own frame and way of musical thinking, which is not always adaptable to musical didactics in terms of notation standards. However, they are adapted and still show that folk songs can be interpolated into the system of music education. From the selected examples of folk songs from Bosnia and Herzegovina, only a small number of examples can be used for illustration, but not for solving specific elements. The notation of Bosnian sevdalinka often contains a series of passing tones that are the result of freedom of interpretation, as well as unresolved metro-rhythmic elements that are not compatible with elementary notation standards.
