Genotoxic effects of inorganic molecule dipotassium-trioxohydroxytetrafluorotriborate, K2(B3O3F4OH), a promising new therapeutic for the epidermal changes treatment, have been evaluated. In vitro analysis included evaluation of genotoxic and cytotoxic potential of K2(B3O3F4OH) in concentrations of 0.01, 0.02, 0.05 and 0.06 mg/mL applying cytokinesis-block micronucleus cytome assay in human lymphocyte culture. With the increase of concentration the frequency of micronuclei elevated but the differences were not significant. Also, there were no significant differences among the frequencies of nuclear buds and nucleoplasmic bridges between controls and treated cultures. Nuclear division index and nuclear division cytotoxycity index values did not reveal significant cytotoxic effect of K2(B3O3F4OH). In vivo genotoxic effects were analyzed on BALB/c mice applying reticulocytes micronucleus assay. K2(B3O3F4OH) was administrated intraperitoneally in final concentrations of 10, 20, 50 and 55 mg/kg. Significant decrease of reticulocytes ratio and increase of micronuclei frequencies against pre-treatments were found for both sampling periods of 48 and 72 hours of the highest applied concentration. This study confirmed that K2(B3O3F4OH) is not genotoxic in tested concentrations in vitro as well as in concentrations lower than 55 mg/kg in vivo. This study presents a reliable basis for further pre-clinical and potential clinical investigations.

The aim of this study was to investigate the distribution of specific phenotypes in patients with lung diseases as well as their eventual association with the risk of developing lung diseases. For this purpose 2777 patients with lung diseases and 2778 healthy individuals from all over Kosova were examined for the appearance of the following selected phenotypes: ear lobe free (ELF)/ear lobe attached, normal chin (NC)/cleft chin, tongue roller (TR)/non roller, hand clasping right thumb over (HC)/hand clasping left thumb over, righthanded (RH)/lefthanded. In addition, the blood group from ABO system and the presence or absence of the Rhesus factor asphenotypical markers were observed. The results obtained show significant differences between control and lung disease patients for NC (p ≤ 0.05) and TR (p ≤ 0.005) as well as for blood groups AB (p ≤ 0.05) and O (p ≤ 0.005). These results point to eventually increased levels of genetic load as a result of the increased homozygosity in some gene loci causing an increased frequency of some recessive phenotypes in patients with lung diseases. Together with the specific associations observed, these preliminary findings could serve as a basis for further in depth investigations with respect to the types of lung diseases, occupational exposure and dietary habits, and thus is expected to contribute to an understanding of predispositions and susceptibility to lung diseases.

Introduction: Progressive pseudorheumatoid dysplasia (PPD) is an autosomal recessive genetic disorder reported to be caused by gene alterations of the Wnt1-inducible signaling pathway protein 3 corresponding gene (WISP3) located on chromosome position 6q22.  Up to date, there is only a handful of WISP3 mutations identified in Europe, whereas most mutations are identified in Asia and Middle East.  According to our knowledge, this is the first report of genetic dissection of WISP3 associated with spondyloepiphyseal dysplasia tarda from Bosnia and Herzegovina. Based on clinical examination findings (general manifestations, physical examination, characteristics of their bones on X-ray and laboratory results), an index patient was directed to WISP3 genotyping for confirmation of suspected diagnosis of PPD.Methods: DNA was extracted from peripheral blood leukocytes. All 5 exons and their exon-intron boundaries of the WISP3 gene were amplified by polymerase chain reaction (PCR) and sequenced by Sanger method. Segregation analysis was done to confirm the familial carrier status.Results: A missense mutation (C223G) - homozygous T to G transition at c.667 in exon 4 was identified in index patient. This mutation changed codon CAG to TAG and resulted in a subsequent change of the cysteine to glycine codon. Same mutation was observed in both parents in heterozygous form confirming the familial segregation.Conclusion: Due to its nature, the identified mutation C223G in exon 4 in WISP3 gene is the most probably causative for PPD in described patient. Here we describe the PCR based method for genotyping of specific mutation in WISP3 gene. The identification of this mutation might be a valuable addition to a regional databases on rare genetic variant although a functional analysis should be performed to explain its pathological effect.

Mitochondrial DNA (mtDNA) variations were analyzed in a sample of 245 individuals of Bosnian-Herzegovinian population from the area of Northeastern Bosnia (also known as Tuzla region). Haplogroup affiliation was determined using RFLP method (Restriction Fragment Length Polymorphism) analyzing haplogroup-specific markers of mtDNA coding region, characteristic for the main Western-Eurasian haplogroups. Additional analyses of two sequenced hypervariable segments (HVSI and HVSII) of mtDNA control region were performed in order to identify U subhaplogroups. The study revealed that 95.51% of the analyzed individuals belonged to the typical Western-Eurasian haplogroups: H, I, J, K, T U, V, W or X. The most frequent haplogroup in the analyzed population was the haplogroup H (52.65%) which, due to its increased frequency, represents a marking haplogroup of the population of Northeastern Bosnia. The results of intergroup genetic analysis showed that Bosnian-Herzegovinian population is genetically closer to previously studied populations of Herzegovinians (part of Bosnia and Herzegovina), Slovenians and Croats in relation to other neighboring populations located in Southeastern Europe. Our study also suggests that population genetic structure of Tuzla region is dominated by mutations that are classified as "Paleolithic". These mutations were probably brought to the area of northeastern Bosnia through waves of prehistoric and historic migrations, but the impact of any pre-Neolithic, Neolithic or some "later" migrations, with a slightly lower contribution to the genetic structure of this population, also cannot be neglected.

Being a crossroad of many ancient and recent historical migrations, Bosnia and Herzegovina (B&H) represents unique spot of multicultural and social diversity. The main aim of this study was to assess genetic structure of three local populations of mountain area from central part of B&H using mtDNA HVS-1 as an informative marker for population genetics studies. A 444 bp HVS-1 segment of control region of mtDNA extracted from buccal swabs was PCR amplified and sequenced. Haplotype and nucleotide diversity, average number of nucleotide differences, AMOVA and pairwise FST based on mtDNA haplotype and haplogroup frequencies were calculated. NJ tree was constructed based on pairwise FST results. Tajima’s D was calculated to evaluate population demographic status.

There are two major theories for inheritance of Rh blood group system: Fisher - Race theory and Wiener theory. Aim of this study was identifying frequency of RHDCE alleles in Bosnian - Herzegovinian population and introduction of this method in screening for Rh phenotype in B&H since this type of analysis was not used for blood typing in B&H before. Rh blood group was typed by Polymerase Chain Reaction, using the protocols and primers previously established by other authors, then carrying out electrophoresis in 2-3% agarose gel. Percentage of Rh positive individuals in our sample is 84.48%, while the percentage of Rh negative individuals is 15.52%. Inter-rater agreement statistic showed perfect agreement (K=1) between the results of Rh blood system detection based on serological and molecular-genetics methods. In conclusion, molecular - genetic methods are suitable for prenatal genotyping and specific cases while standard serological method is suitable for high-throughput of samples.

Diversity of nuclear microsatellite markers were analyzed in a reference sample of the population of northeast Bosnia and Herzegovina. 437 samples taken from unrelated individuals were processed and three samples of paternity proof were shown. Detection effectiveness profile of the research, points to a valid choice of method of extraction, amplification and genotyping short tandem repeat (STR) loci with PowerPlextm16 kit. Genetic analysis of allelic variants of the 15 STR loci PowerPlextm16 kit detected 17 samples determined as rare allelic variants or microvariants. Samples were divided into 15 different allelic variants at 7 different loci, and are: in locus D7S820, D16S539, D3S1358, D18S51, PENTA D, PENTA E and in locus vWA. Genetic analysis of mutations in cases of paternity determined three examples of single-step mutations in the loci FGA, Penta D and D3S1358. Genetic analysis of observed STR loci detected three allelic variant of genotype combination 7/10/11.3 in locus D7S820 Type II. Population genetic analysis of STR loci in a representative sample of the population of northeast Bosnia and Herzegovina included the application of the assessment tests of within-population genetic diversity and interpopulation diversity, as well as genetic differentiation between populations: North-eastern Bosnia and Herzegovina (BH) and BH general reference, then the Croatian population, Macedonian, Serbian and Slovenian. Based on the result analysis of specific forensic parameters, it can be assumed that the most informative marker is PENTA E for population genetic analysis and forensic testing in the population of northeast Bosnia and Herzegovina. Research results fit regional STR database of this part of Europe.

MtDNA variations, determined in terms of mtDNA haplogroups, were analyzed, the sample consisted of the human population of Bosnia and Herzegovina from the teritory of the Tuzla region. The analysis included a total of 245 mtDNA samples (kin unrelated individuals). Determination of mtDNA haplogroups was studied by using haplogroup-specific PCR-RFLP markers of a coding region of mtDNA. We observed that 95.11% of investigated individuals in the Tuzla region belong to the Western-Euroasian mtDNA haplogroups: H, V, T, I, J, K, U, X, W. The impact of migratory activities on the population structure of the Tuzla region was estimated by analysis within- and of intergroup genetic differences (index of genetic specificities, pairwise FST analysis and exact-p test) of indigenous and migrant categories (recent, internal, and historical). The analysis showed that a significant demographic influence on the genetic structure of indigenous people was exerted by the category of recent migrants only.
