This study investigates the genetic diversity and relatedness among a small local population in Bosnia and Herzegovina. In a genetic research study, a sample of 38 individuals was collected from the village of Vukotići, consisting of 21 male and 17 female subjects. The total genomic DNA was extracted using a modified Miller protocol. The QUANTIFILER DNA identification kit was used to quantify the total human DNA in the sample. The sibship relationship was assessed by computing the likelihood ratio for each of the 15 STR loci in both relatives and non-relatives. Results showed a higher homogeneity of the small local population compared to the mixed population within the larger population. Variability in peak height observed in the genetic analysis was attributed to differences in DNA concentration in the extracted samples. Probability of relatedness among participants in the Vukotići village was found to be low. Central tendency and variability measures revealed valuable insights into sample distribution and variation. The study concludes that CSI=1 and CSI=3 can be used as reliable tools to determine sibship in small local populations without a "gray zone".

Objectives: The global burden of the current severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causing the corona virus disease-19 (COVID-19) is enormous No definitive treatment and prophylactic guidelines for COVID-19 currently exist except for physical distancing and aerial barriers between individuals This work explored the natural compound-binding efficiency of SARS-CoV-2 proteins essential for host cell interaction and infection Methods: The binding activity of artemisinin to SARS-CoV-2 spike glycoprotein (Protein Data Bank (PDB) ID: 6VYB), SARS-CoV-2 main protease (3C-like main protease (3CLpro);PDB ID: 6Y84) and SARS-CoV-2 papain-like protease (PLpro;PDB ID: 6W9C), were tested using in silico methods Moreover, chloroquine and hesperidin were used as the positive control of binding affinity and proven therapeutic effect, respectively Results: The highest affinities for binding to all tested SARS-CoV-2 proteins are observed for hesperidin (-5 8,-10 0, and -8 1 kcal/mol), then for artemisinin (-4 8,-8 3, and -6 0 kcal/mol), and the lowest for chloroquine (-4 1,-8 2, and -4 8 kcal/mol) Artemisinin, hesperidin, and chloroquine had similar positioning toward targeted proteins at specific sites when these interactions were visualized Conclusion: This study shows that artemisinin has the potential to bind and inhibit the SARS-CoV-2 spike protein, the 3CLpro main protease, and PLpro proteinase similar to hesperidin and chloroquine that have been proven as antivirals in previous preclinical and clinical studies
