Receptor for advanced glycation end products (RAGE) plays a role in atherosclerosis in diabetics. There are two functional polymorphisms in the promoter of the RAGE gene (-429T/C and -374T/A). The aim of this study was to look for a relationship between the -429T/C and the -374T/A gene polymorphisms of the RAGE gene and the development of coronary artery disease (CAD) in the Slovene population with type 2 diabetes of duration longer than 10 years. One hundred and sixty-eight subjects with diabetes and CAD were compared to 241 diabetic subjects without CAD. The -429T/C and the -374T/A RAGE genotype distributions in patients with CAD (-429T/C: CC: 3%, TC: 31%, TT: 66.0%; -374T/A:AA: 7.7%, TA: 48.2%, TT: 44.1%) were not significantly different from those in patients without CAD (-429 T/C: CC: 1.7%, TC: 26.1%, TT: 72.2%; -374T/A: AA: 11.2%, TA: 43.2%, TT: 45.6%). Our study failed to demonstrate an association between either the -429T/C or the -374T/A gene polymorphism of the RAGE gene and CAD in the Slovene population with type 2 diabetes of duration longer than 10 years.

In order to investigate the contribution of the atrial natriuretic factor (ANF) gene in pathogenesis of essential arterial hypertension (EAH), we analyzed the ScaI gene polymorphism of the ANF gene in a group of children with EAH. Fifty-eight children, aged 8-19 years, with the diagnosis of EAH were included in the association study and were compared to 57 subjects with normal blood pressure (the control group). Arterial hypertension was defined as systolic/diastolic blood pressure higher than the 95th age-gender-height percentile of the adopted reference values. We failed to demonstrate an association between the ScaI ANF gene polymorphism and EAH in childhood (OR = 2; 95% CI 0.9-4.2; p = 0.07), however, we provided evidence of an interaction between the ScaI ANF gene polymorphism and obesity defined as BMI over the 85th percentile (OR = 13.1; 95% CI 1.6-106; p < 0.001).

Mitochondrial DNA polymorphisms were analyzed in of 1,610 randomly chosen adult men from 11 different regions from southeastern Europe (Croatians, Bosnians and Herzegovinians, Serbians, Macedonians and Macedonian Romani). MtDNA HVS-I region together with RFLP sites diagnostic for main Euroasian and African mtDNA haplogroups were typed to determine haplogroup frequency distribution. The most frequent haplogroup in studied populations was H with the exception of Macedonian Romani among whom the most frequent were South Asian (Indian) specific variants of haplogroup M. The multidimensional scaling plot showed two clusters of populations and two outliers (Macedonian Romani and the most distant from mainland Croatian island of Korcula). The first cluster was formed by populations from three Croatian islands (Hvar, Krk and Brac) and the second cluster was formed by Macedonians, Serbians, Croatians from mainland and coast, Herzegovinians, Bosnians, Slovenians, Poles and Russians. The present analysis does not address a precise evaluation of phylogenetic relations of studied populations although some conclusions about historical migrations could be noticed. More extended conclusions will be possible after deeper phylogenetic and statistical analyses.

Dynamics of growth of male children and youths from the Region of Tuzla influenced by some exogenous factors was researched by a corresponding analysis of the sample which included 751 tested individuals, aged from 11 to 17 years. The analysis performed is primarily based on the scientific elaboration of the registered state in two time-points (1996 and 1999) in the tested part of broader population. This research involved the period of four-year aggression on Bosnia and Herzegovina, taking into consideration the fact that the tested persons spent one period of their growth and development in extremely bad wartime living conditions. By quasicanonic correlative analysis it was established that the next factors participated in connection of variables of both sets (initial and final measurements): mother's standard, total mother's and father's standard of living, mother's age and sequence of births participated to some less extent in connection of both sets of variables. Anthropometric variables that had most significant impact of both sets of variables are: length parameters, body mass, width parameters, circumferences had somewhat less impact, while indexes of head and sitting height had the least impact on this connection.

Angiotensin II is the major effector molecule of renin-angiotensin system; its production can be conveniently interrupted by angiotensin-converting enzyme (ACE). Typical plasma levels of ACE accompany the I/D polymorphism; however, a controversy exists as to whether the DD genotype of the ACE polymorphism affects the risk for the development of coronary artery disease (CAD) and to what extent the ACE polymorphism is associated with CAD in different populations. We compared the I/D polymorphism in 212 CAD patients younger than 50 years with 165 healthy control individuals. They were all from the Tuzla region in Bosnia and Herzegovina. Patients with CAD had a higher prevalence of the DD genotype (36.3%) than controls (25.6%). The odds ratio for the ACE DD genotype in CAD patients was 1.7 (95% confidence interval 1.0-2.7; p < 0.05). We may conclude that the D/D genotype of the ACE gene polymorphism is associated with an increased risk for CAD in the Bosnian population.

The project is an international comparative study on risk and protective factors of adolescent health and well-being, with particular focus on youth with immigrant (or refugee) experience. This is a comprehensive study on the quality of life and health outcomes of adolescent youth that looks at group-specific differences within different socio-cultural contexts across six European countries, including those of post-conflict communities. The research project combines both quantitative and qualitative methods, using a common set up across all countries involved with the goal of collecting data on 3500 adolescents that are strictly comparable to allow cross-country analyses. It is particularly aimed at increasing the understanding of acculturation processes of a particularly sensitive population of adolescent refugees and immigrants and of the influence that the interaction of contextual and developmental factors has on their mental health and psychological well-being.
