Abstract
Musculoskeletal research should synergistically investigate bone and muscle to inform approaches for maintaining mobility and to avoid bone fractures. The relationship between sarcopenia and osteoporosis, integrated in the term 'osteosarcopenia', is underscored by the close association shown between these two conditions in many studies, whereby one entity emerges as a predictor of the other. In a recent workshop of Working Group (WG) 2 of the EU Cooperation in Science and Technology (COST) Action 'Genomics of MusculoSkeletal traits Translational Network' (GEMSTONE) consortium (CA18139), muscle characterization was highlighted as being important, but currently under-recognized in the musculoskeletal field. Here, we summarize the opinions of the Consortium and research questions around translational and clinical musculoskeletal research, discussing muscle phenotyping in human experimental research and in two animal models: zebrafish and mouse.

Abstract
BACKGROUND CYP3A5 enzyme encoded by CYP3A5 is important for drug metabolism in gut and liver, whereas P-glycoprotein by ABCB1, is an ATP-dependent drug efflux pump which exports endo- and exogenous substances outside the cell. Aim: The study was to assess the prevalence of CYP3A5 alleles: *1, *2, *3, *4, *6 and *7, and C and T of ABCB1 in Poles, Belarusians and Bosnians and to compare it with the data reported from other European populations. Subjects and methods: Overall, 511 unrelated healthy subjects from Poland (n = 239), Belarus (n = 104) and Bosnia and Herzegovina (n = 168) were included in this study. Allele frequencies and statistical parameters (AMOVA version 2.9.3) were determined. Results: In Poles, Belarusians and Bosnians the *3 allele of CYP3A5 was the most common, and wild-type allele *1, were: 5.8%, 1.6% and 2.1%, respectively. Allele *2 was very rare, and alleles *4, *6 and *7 were not detected. For the populations mentioned above, the ABCB1 allele C was: 48.1%, 51.4%, 52.4%, respectively. CONCLUSION In compared populations, the distribution of CYP3A5 variants but not ABCB1, differed significantly. Alleles *4, *6 and *7 of CYP3A5 did not occur or occurred rarely.

Abstract
Background Lipids and lipoproteins are significantly involved in maintaining structural and functional components of the human brain and neurons, but their role in the development of Alzheimer's disease (AD) and vascular dementia (VD) remains unclear. Objective The aim of the present study was to explore the differences in the standard and novel lipid profile parameters in patients with AD and VD, stratified by the degree of cognitive impairment (CI). Methods Present study included 66 patients with AD, 50 patients with VD, and 60 control subjects. For an evaluation of the global cognitive function the Montreal Cognitive Assessment (MoCA) test was used. In order to distinguish patients with VD from those with AD the Hachinski ischemic score was used. Plasma total cholesterol (TC), high-density lipoprotein -cholesterol (HDL-C), and triglycerides (TG) levels were determined using standard enzymatic colorimetric techniques, whereas the Friedewald formula was used to calculate low-density lipoprotein-cholesterol (LDL-C) levels. The non-traditional lipid indices such as TG/HDL-C, TC/HDL-C, and LDL-C/HDL-C ratio were separately calculated. The differences between the groups were analyzed with the Kruskal Wallis test followed by the Mann-Whitney test or with ANOVA followed by the Tuckey posthoc test. Results Results of the conducted study have found that the patients in AD group with moderate CI and patients in AD group with severe CI exhibited significantly lower levels of serum TC, TG, LDL-C, VLDL-C, Non- HDL-C, atherogenic index, TG/HDL-C, TC/HDL-C and LDL-C/HDL-C compared to cognitively normal control subjects. Moreover, patients in VD group with severe and moderate CI had significantly lower level of TG compared to control group of subjects. Our results have also shown that patients in AD group with moderate CI had significantly lower level of TC, TG, LDL-C, Non-HDL-C, atherogenic index, TG/HDL-C, TC/HDL-C compared to VD patients with moderate CI. In addition, patients in AD group with severe CI had significantly lower level of TC, LDL-C, Non-HDL-C and TC/HDL-C compared to VD patients with severe CI. Conclusion The results of this study have shown dysregulation of lipid metabolism in AD and VD patients with different degree of CI. In both moderate and in severe CI, patients with AD had lower levels of majority of standard and novel lipid parameters compared to patients with VD. Further larger prospective studies are required to elucidate the accuracy of standard and novel lipid parameters in the assessment of different degree of CI in AD and VD.

Abstract
Background: Conflicting data exist on traditional lipid profiles in patients with Alzheimer’s disease (AD) and vascular dementia (VD), whereas scarce number of studies evaluated non-traditional lipid profiles in patients with AD and VD. Studies have shown that ethnic background may affect lipid profile. Objective: The aim of the present study was to conduct comparative assessment of traditional and non-traditional lipid profiles in Bosnian patients with AD and VD. Methods: A controlled, cross-sectional study was performed with 66 patients with AD, 50 patients with VD, and 60 control subjects. The Montreal Cognitive Assessment (MoCA) test was used for an evaluation of the global cognitive function. The Hachinski ischemic score was used to distinguish patients with VD from those with AD. Plasma total cholesterol (TC), high-density lipoprotein -cholesterol (HDL-C), and triglycerides (TG) levels were determined using standard enzymatic colorimetric techniques, whereas the Friedewald formula was used to calculate low-density lipoprotein-cholesterol (LDL-C) levels. The non-traditional lipid indices such as TG/HDL-C, TC/HDL-C, and LDL-C/HDL-C ratio were separately calculated. The differences between the groups were analyzed with ANOVA followed by the Tuckey posthoc test or with the Kruskal Wallis test followed by the Mann-Whitney test. Results: Results of the present study have shown that patients in AD group had significantly lower level of TC, TG, LDL-C, VLDL-C, Non-HDL-C and significantly lower atherogenic index compared to the control group (CG) and compared to the VD patients. Significant difference in values of TG and VLDL-C was observed between VD and the CG, whereas no significant difference in values of TC, LDL-C, atherogenic index and Non-HDL-C was observed between these two groups. Our results have also shown that TG/HDL-C, TC/HDL-C, and LDL-C/HDL-C ratios were significantly lower in AD patients compared to the VD and CG. Moreover, TG/HDL-C ratio was significantly lower in VD compared to the CG. However, a significant difference in TC/HDL-C and LDL-C/HDL-C was not observed between VD and the CG. Conclusion: Based on the results of the present study it can be deduced that there is a difference in traditional and non-traditional lipid profiles between AD and VD patients of Bosnian descent. Obtained results suggest that lipids are decreased in AD and in VD to a certain extent. However, since there is an inconsistence in literature whether there is an association between cholesterol and cognition, large prospective studies are required to elucidate this controversy.

Abstract
A synoptic overview of scientific methods applied in bone and associated research fields across species has yet to be published. Experts from the EU Cost Action GEMSTONE ("GEnomics of MusculoSkeletal Traits translational Network") Working Group 2 present an overview of the routine techniques as well as clinical and research approaches employed to characterize bone phenotypes in humans and selected animal models (mice and zebrafish) of health and disease. The goal is consolidation of knowledge and a map for future research. This expert paper provides a comprehensive overview of state-of-the-art technologies to investigate bone properties in humans and animals - including their strengths and weaknesses. New research methodologies are outlined and future strategies are discussed to combine phenotypic with rapidly developing -omics data in order to advance musculoskeletal research and move towards "personalised medicine".

Abstract
Musculoskeletal research has been enriched in the past ten years with a great wealth of new discoveries arising from genome wide association studies (GWAS). In addition to the novel factors identified by GWAS, the advent of whole-genome and whole-exome sequencing efforts in family based studies has also identified new genes and pathways. However, the function and the mechanisms by which such genes influence clinical traits remain largely unknown. There is imperative need to bring multidisciplinary expertise together that will allow translating these genomic discoveries into useful clinical applications with the potential of improving patient care. Therefore "GEnomics of MusculoSkeletal traits TranslatiOnal NEtwork" (GEMSTONE) aims to set the ground for the: 1) functional characterization of discovered genes and pathways; 2) understanding of the correspondence between molecular and clinical assessments; and 3) implementation of novel methodological approaches. This research network is funded by The European Cooperation in Science and Technology (COST). GEMSTONE includes six working groups (WG), each with specific objectives: WG1-Study populations and expertise groups: creating, maintaining and updating an inventory of experts and resources (studies and datasets) participating in the network, helping to assemble focus groups defined by phenotype, functional and methodological expertise. WG2-Phenotyping: describe ways to decompose the phenotypes of the different functional studies into meaningful components that will aid the interpretation of identified biological pathways. WG3 Monogenic conditions - human KO models: makes an inventory of genes underlying musculoskeletal monogenic conditions that aids the assignment of genes to GWAS signals and prioritizing GWAS genes as candidates responsible for monogenic presentations, through biological plausibility. WG4 Functional investigations: creating a roadmap of genes and pathways to be prioritized for functional assessment in cell and organism models of the musculoskeletal system. WG5 Bioinformatics seeks the integration of the knowledge derived from the distinct efforts, with particular emphasis on systems biology and artificial intelligence applications. Finally, WG6 Translational outreach: makes a synopsis of the knowledge derived from the distinct efforts, allowing to prioritize factors within biological pathways, use refined disease trait definitions and/or improve study design of future investigations in a potential therapeutic context (e.g. clinical trials) for musculoskeletal diseases.

Abstract
Purpose Vitamin D3 (vit-D3) is a potent immunomodulator with anti-inflammatory and antioxidative properties. We used streptozotocin (STZ)-induced rat model of diabetes (DM) to evaluate the effects of vit-D3. We measured serum biochemical parameters, interleukin-17 (IL-17), osteocalcin (OC), malondialdehyde (MDA), and immune cell count on the 21st day of experiment. Method A total of 24 Wistar rats were randomly divided into three groups. Each group had eight rats. During the 1st day of the experiment, the control group was injected intraperitoneally with citrate buffer, while STZ group and STZ + vit-D3 group were injected by a single i.p. dose (35 mg/kg) of STZ dissolved in citrate buffer (pH 4,5; 0,1 M). Vitamin D3 was applied via oral gavage once daily to the STZ + vit-D3 group for a total period of 14 days, starting from the 7th day of the experiment. Results STZ rats showed a significant reduction in OC and an increase in MDA and IL-17 serum concentrations compared to the control rats. We also observed a significant STZ-associated decrease in the number of lymphocytes and a significant increase in monocyte and eosinophil number. Oral treatment with vit-D3 to STZ-induced diabetic rats significantly increased OC and decreased MDA serum levels. Furthermore, vit-D3 treatment resulted in a good regulation of hematopoiesis such as increase in the number of segmented granulocytes and lymphocytes and a reduction in the number of monocytes and eosinophils. Conclusion Vit-D3 treatment has important therapeutic effects; among many others it can attenuate oxidative stress and ameliorate the hyperglycemic state in the STZ-induced rat diabetic model, which is promising for further clinical trials.

Abstract
BACKGROUND Cerebrospinal levels of isoprostanes (IsoPs) have been established as biomarkers of oxidative stress in Alzheimer's disease (AD) and vascular dementia (VD). The value of peripheral levels in the diagnostics of these diseases is less conclusive. The aim of this study was to determine serum 8-iso-prostaglandin-F2alpha (8-iso-PGF2α) levels in Bosnian AD and VD patients and to establish whether there is an association between 8-iso-PGF2α serum concentration and cognitive impairment (CI) in patients with dementia. SUBJECTS AND METHODS Serum levels of 8-iso-PGF2α were measured by enzyme immunoassay method in AD (n=30) and VD patients (n=30) and control subjects (CG, n=30). The AD and VD group were further stratified according to the level of CI. RESULTS The serum 8-iso-PGF2α levels were significantly higher in the AD (74.00 pg/mL) and VD groups (38.00 pg/mL) compared to the CG (17.50 pg/mL). A significant difference in serum 8-iso-PGF2α levels between patients with moderate and severe CI was not established in either AD or VD. CONCLUSION Serum 8-iso-PGF2α proved to be a good biomarker in AD and VD, however it cannot be recommended for the differentiation of moderate and severe CI.

Abstract
Introduction: Poor glycemic control, assessed by higher glycated hemoglobin (HbA1c) levels, is associated with greater risk of diabetic complications. Aim: The aim of this study was to assess the association of triglyceride - to - HDL cholesterol (TG/HDL-C) ratio and triglyceride glucose (TyG) index with HbA1c and to evaluate their potential role as predictors of glycemic control in patients with diabetes mellitus type 2 (DM2). Patients and methods: This cross-sectional study was conducted in Health Center Banovici and included a total of 113 patients with DM2 classified according to their HbA1c values in two groups: DM2 HbA1c <7% - DM2 patients with good glycemic control (n=39) and DM2 HbA1c ≥7% - DM2 patients with poor glycemic control (n=74). Anthropometric, biochemical parameters and blood pressure values were measured, while TG/HDL-C ratio and TyG index were calculated. Results: TG/HDL-C ratio and TyG index were significantly higher in DM2 HbA1c≥7% compared to DM2 HbA1c<7% group (p=0.003 and p<0.001; respectively). Both TG/HDL-C ratio and TyG index were positively associated with HbA1c levels (Rho=0.29; p=0.002; Rho=0.37; p<0.001; respectively). In linear regression analysis TG/HDL-C ratio and BMI, and also TyG index and BMI were significantly independently associated with HbA1c even after controlling for age, gender, diabetes duration and smoking. When we stratified patients according to BMI values, independent association between TG/HDL-C ratio and HbA1c remained significant only in normal weight subjects (OR 0.21; 95%CI: 0.05-0.37; β=0.65; p=0.017), while independent association between TyG index and HbA1c remained significant only in overweight and obese subjects (OR 0.063; 95%CI: 0.01- 0.12; β=0.24; p =0.027). Conclusion: TG/HDL-C ratio might be a useful predictor of glycemic control in normal weight, and TyG index in overweight and obese patients with DM2.

Abstract
Introduction: Hypertension is significantly contributing to global mortality and morbidity and has been identified as the most important modifiable risk factor for early development of cardiovascular diseases (CVD). Aim: The aim of this study was to investigate the efficacy of different combinations of antihypertensive therapy on blood pressure, arterial stiffness and peripheral resistance in patients with essential hypertension using the brachial oscillometric ambulatory blood pressure monitor. Methods: This study was designed as an observational, prospective, multi centric study conducted in eight primary care centers of the Health Center of Canton Sarajevo during the period of six months. The study included 655 participants, both genders, aged between 30 and 75, who were diagnosed with hypertension according to the ESC/ESH guidelines. Participants were divided into six treatment groups based on the hypertensive drug therapy they were using; lisinopril, losartan or valsartan alone or in combination with hydrochlorothiazide (A, B and C group respectively) or combination of lisinopril, losartan or valsartan with/without hydrochlorothiazide together with amlodipine (D, E and F respectively). The participants were monitored at baseline, after 3 and 6 months (1st and 2nd follow-up). Brachial oscillometric ambulatory blood pressure monitor was used for measuring systolic (SBP), diastolic (DBP), pulse pressure (PP), pulse wave velocity (PWV) and peripheral resistance (PR). Results: SBP, DPB, PP, and PWV significantly decreased from baseline to 2nd follow-up in all treatment groups. The mean reductions in SBP were from -11.7 (95%CI; 9.3- 14.1) to -23.2 (95%CI; 18.3-28.1) mmHg and DBP reductions varied from -5.5 (95%CI; 3.9- 7.1) to -13.4 (95%CI; 7.7-19.1) mmHg. PWV decreased in all treatment groups (from -3.3% to -8.2%). Treatment regiment was not associated with significant differences in SBP, DBP, PP or PWV reductions or their values measured at 2nd follow-up. Peripheral resistance significantly decreased only in group C (p=0.011), group D (p=0.009) and group F (p=0.027). Conclusion: These data suggest that lisinopril/lisinopril + hydrochlorothiazide, losartan/losartan + hydrochlorothiazide and valsartan/valsartan + hydrochlorothiazide alone or in combination with amlodipine are equally effective and well tolerated for the reduction of both systolic and diastolic blood pressure and improve arterial stiffness in patients with essential hypertension.

Abstract
Previous research suggested that several genetic polymorphisms are associated with increased risk of ischaemic stroke (IS) in young adults. However, the predictive biomarkers of IS in young adults are still unclear. Our aim was to assess the contribution of modifiable and genetic factors in IS in young adults. In total, 40 stroke patients and 40 healthy controls aged 20 to 50 years were recruited. Data on modifiable factors were collected, then participants were genotyped for seven SNPs linked to thrombophilia: ACE rs1799752, PAI-1 rs1799889, APOE rs1412 and rs429358, FV rs6025 and rs1800595, and FII rs62623459. Significantly increased risk factors: hypertension and dyslipidaemia in stroke patients compared with the controls: 50.0 % vs 27.5 % and 75.0 % vs 40.0% (P = 0.039 and P = 0.002, respectively) were observed. Stroke patients compared with controls did not differ in distribution of ACE, APOE, FV, and FII variants. The 4G4G homozygotes of the PAI-1 gene were significantly more prevalent in stroke patients compared to the controls: 42.5 % vs 17.5 %, (P = 0.033). In the group with the small vessel occlusion subtype of stroke, statistically significant overrepresentation of 4G4G homozygotes and frequency of the 4G allele compared with controls: 57.1 % vs 17.5 % and 0.7 vs 0.45 (P = 0.026 and P = 0.03, respectively) were observed. Independent predictors of stroke incident were: dyslipidaemia (OR (95% CI) = 4.2 (1.4-12.4)) and 4G4G genotype (OR (95% CI) = 3.9 (1.1-13.7)). These results confirm the contribution of dyslipidaemia and 4G4G genotype in the increased risk of IS in young Bosnian adults.

Abstract
Introduction Symptomatic and etiopathologic heterogeneity of schizophrenia (SCH) and bipolar disorder (BD) can be adequately addressed using a dimensional approach to psychopathology, as well as interpreting physiological properties and markers as predictors of disease onset and relapse. Risk factors, genetic and environmental, are likely to modify the neurobiological processes characteristic of certain physiological processes that manifest to a greater degree of overlapping symptoms. One of the most common laboratory tests in psychiatric patients is a standard laboratory blood test. It gives us an insight into the general somatic condition of the patient. It assesses the ability to transport oxygen to tissues and carbon dioxide back to the lungs via erythrocytes (RBC) and hemoglobin (HGB) as their most important constituents, and is also an indicator of iron status and blood oxygenation. Aim Schizophrenia (SCH) and bipolar disorder (BD) are psychiatric disorders whose complex etiology and pathogenesis are still far from known. A correlation between red blood cell abnormalities and these diseases has been recognized in some studies. One of the most common laboratory tests in psychiatric patients is a standard laboratory blood test. However, so far there is a small number of published papers that relate to the relationship between laboratory parameters of blood and the aim of this paper is to reveal more light in this subject. Methods The research was done as an observational prospective clinical study that has evaluated different physiological and pathological parameters in patients with BD and SCH over a two-year period. A total of 159 patients with schizophrenia, 61 patients diagnosed with bipolar disorder and 82 healthy subjects participated in this study. Results At baseline, BD compared to SCH patients had higher mean lymphocyte count (2,6±0,7 vs. 2,0±0,6x109; p=0,006) and haemoglobin concentration (146,8±12,2 vs. 140,2±14,7 g/L; p=0,03), and significantly lower red cell distribution width (13,6±2,2 vs. 14,7±1,8%; p=0,008). In both BD and SCH patients there was a significant number of patients with low red blood cells count and low haemoglobin concentration, and high MCH and MCHC at baseline and at 3 and 6 months of follow up. Conclusions The finding that SCH as well as BD differed from controls with respect to red blood cells, hemoglobin, lymphocytes, and average platelet count was consistent with previous findings and could be understood as a qualitative measure in the evaluation of this sample. The fact that no association with other parameters was found, as well as an association with the diagnosis, does not exclude that these associations can be found in larger samples.

Abstract
Introduction: Although many predictive tools have already been developed, efforts are still proceeding to identify a reliable biomarker to predict the prognosis of the patients with acute heart disorders. Objectives: The aim was to evaluate the role of renal injury biomarkers (serum cystatin C, serum and urine interleukin-18, IL-18) and heart failure biomarkers (plasma B-type natriuretic peptide, BNP) in the prediction of the postdischarge requirement of renal replacement therapy (RRT) and/or 6-month mortality in patients with acute heart disorders. Patients and Methods: In patients diagnosed with acute heart disorders (acute heart failure [AHF] and/or acute coronary syndrome [ACS]) and admitted to the intensive care units, baseline clinical parameters, renal and cardiac biomarkers were determined. Patients were followed up for 6 months. The composite outcome was the postdischarge requirement of RRT and/or 6-month mortality. Results: Of 120 patients, 5.8% continued RRT after discharge. The 6-month mortality was 20%. Cox logistic regression analysis showed that urine IL-18 (P=0.021), plasma BNP (P=0.046), Acute Physiology and Chronic Health Evaluation (APACHE) II score (P=0.002), and left ventricular diastolic dysfunction (P=0.045) were independent predictors of the postdischarge requirement of RRT and/or 6-month mortality. For predicting RRT and/or 6-month mortality, using urine IL-18 cutoff value of 29.1 pg/mL showed 66.7% sensitivity and 67.7% specificity (area under the curve, AUC 0.70, P=0.003), while using plasma BNP cutoff value of 881.6 pg/mL showed 66.7% sensitivity and 70.8% specificity (AUC 0.76, P<0.001). Conclusion: Urine IL-18 and plasma BNP are independently predictive for the postdischarge requirement of RRT and/or 6-month mortality in patients with acute heart disorders.

Abstract
OBJECTIVES Although Dual-energy X-ray Absorptiometry (DXA) is gold standard for osteoporosis diagnosis, several reports have shown discordant T-score values measured by Quantitative Computed Tomography (QCT) and DXA especially in obese subjects, but it is still not clear whether BMD measurement by two modalities is affected by overall obesity or central obesity in postmenopausal females. Therefore, the aims of this study were to compare BMD and T-scores by DXA and QCT and to evaluate whether these two osteoporosis assessment modalities yield different T-score values in postmenopausal females with obesity and central obesity. METHODS This cross-sectional study enrolled 44 postmenopausal females, referred for osteoporosis screening. Anthropometric indices (BMI-body mass index, WC-waist circumference and ICOindex of central obesity) were measured and females underwent an assessment of bone mineral density by DXA and QCT. RESULTS Lumbar Spine (LS) T-score values were observed to be significantly lower by DXA compared to qCT in females with BMI >25 kg/m2, (-1.9±1.5 vs. -2.3±1.2; p=0.039), in females with WC>88 cm(-1.9±1.5 vs. -2.4±1.2; p=0.008) and in females with ICO>0.5(-1.96±1.4 vs. -2.5±1.2; p=0.004). However, in normal-weight females and in those without central obesity, LS T-scores by DXA were not different than qCT. DXA at lumbar spine and proximal femur revealed osteoporosis in 47.7% and 11.4% respectively, while QCT detected osteoporosis in 61.4% of females (p<0.001). Measures of central obesity; ICO and WC were not associated with QCT bone mineral density (BMD) (r=0.14 and r=0.21, respectively), but were positively associated with both DXALS BMD (r=0.29 and r=0.31; p<0.05) and DXA proximal femur BMD (r=0.41 and r=0.44; p<0.01). CONCLUSION Our results suggest that obesity is associated with lower T-scores by DXA compared to QCT. Caution is needed when assessing osteoporosis status in obese postmenopausal females. However, further studies with larger sample size are needed to confirm the findings.

Aim: To assess the utility of gamma-glutamyl transferase (GGT) and C-reactive protein (CRP) in predicting troponin elevation in patients with acute coronary syndrome. Patients: The total of 119 patients were divided into troponin-positive (n = 61) and troponin-negative (n = 58) patients. Results: CRP cut-off value ≥13.4 mg/l had the sensitivity of 68.1% and specificity of 62.5%, while the GGT cut-off value ≥61.5 IU/l had the sensitivity of 66.0% and specificity of 62.0% and combined use of both CRP and GGT had 71.4% sensitivity and 69.6% specificity in predicting troponin increase in acute coronary syndrome patients. Conclusion: GGT might be used as an adjuvant marker for risk assessment patients who present with chest pain and are suspected to have acute coronary syndrome.

Abstract
Due to inconsistent results of APOE variants in the survival of pregnancy we investigated the potential relationship of APOE rs7412 and rs429358 with pregnancy loss (PL) in Bosnian women. We enrolled 154 women with PL. The minimum week of miscarriage was 6, while the maximum was 28. As a control group, an equal number of mothers with at least one live-born child was included. All women were recruited from the Institution of Health Protection of Women and Motherhood in Sarajevo, Bosnia and Herzegovina. Genotyping was performed by real- time PCR at the Department of General Pharmacology and Pharmacoeconomics, Pomeranian Medical University. The prevalence of genotypes E2/E3, E2/E4, E3/E3, E3/E4, E4/E4 in the group with and without PL were: 14.3 %, 1.3 %, 70.8 %, 12.3 %, 1.3 %, and 13.6 %, 1.3 %, 70.1 %, 14.3 %, 0.7 %, respectively. The frequency of the E4/E4 genotype in women with 1-2 and 3-4 PL compared to women without PL did not differ significantly between those three groups (P value = 0.0712). The frequencies of alleles ԑ2, ԑ3, ԑ4 in the group with and without PL were: 6.8 %, 85.1 %, 8.1 % and 7.5 %, 84.1 %, 8.4 %, respectively, and did not differ significantly. We conclude that our study does not confirm rs7412 and rs429358 as a potential risk factor for PL in the studied group. To elucidate the relationship between PL and variants of the APOE gene, studies with a larger sample size and placental histomorphology and genetic diagnosis are required.

Abstract
Introduction Several analysis for different population conclude that endothelial plasminogen activator inhibitor 1 gene polymorphism, -675 ID, 4G/5G PAI-1 (ref SNP ID: rs1799889, also described as rs34857375, has merged into rs1799762) may increase risk of pregnancy loss (PL). However, there is a disagreement as to the association 4G allele with pregnancy loss. Aim Therefore, we decided to investigate the -675 ID, 4G/5G PAI-1 as a potential genetic factor linked to PL in European and worldwide populations. A systematic review of the scientific literature was conducted with the use of the PubMed and Scopus electronic databases (1991-present), using the following search terms: pregnancy loss, miscarriage, genetic risk of thrombophilia, rs1799889 PAI-1 gen, 4G/5G PAI-1 gene polymorphism, PAI-1 gene locus 4G/5G polymorphism. Results Among European populations, the statistically significant association between 4G allele and recurrent PL only in Czechs and Bulgarian women was found (p<0.002 and p=0.018, respectively); while, among populations outside Europe in Iranian, Tunisian and Turkish women (each p<0.001). Conclusions We concluded, that both in Europe and elsewhere in the world, the high frequency of 4G allele in population, is not unambiguously linked with the risk of pregnancy loss.

Abstract
The relationship between genetic risk factors of thrombophilia and pregnancy loss (PL) is being discussed. The focus has been on F5 1691G>A, F2 20210G>A, and MTHFR 677C>T polymorphisms that may predispose women to microthrombosis during the stages of embryo implantation and placentation. Although, the frequencies of these polymorphisms were reported in different populations, such studies have not yet been performed in Bosnian population. In this study, we determined the prevalence of F5 G>A (rs6025), F2 G>A (rs1799963) and MTHFR C>T (rs1801133) polymorphisms in Bosnian women. A total of 154 women with PL, mean age 33 (±5.4) years, were enrolled in the study. As a control group, 154 mothers [mean age 31.4 (±6.7) years] with at least one live-born child were included. We used real-time polymerase chain reaction (PCR) to determine the frequencies of F5 G>A and F2 G>A genotypes, and PCR-restriction fragment length polymorphism (RFLP) for analyzing MTHFR C>T genotypes. The frequency of heterozygotes for F5 and F2 was significantly higher in women with venous thrombosis (VT) compared to women without VT (p = 0.047 and p = 0.001, respectively). There was no significant difference in the distribution of MTHFR genotypes and alleles between these two groups. In addition, we observed no significant differences in the genotype and allele frequencies between the group with PL and control group, for all investigated polymorphisms. The allele frequencies for 1691A (F5), 20210A (F2), and 677T (MTHFR) reported in this study are consistent with the data obtained for other European countries, however, we were not able to confirm the association between the three polymorphisms and PL in Bosnian women.

Abstract
BACKGROUND The ε2, ε3 and ε4 alleles of APOE gene have been associated with several diseases in different populations. Data on the frequency of alleles are used in both a clinical and evolutionary context. Although the data on frequency of these alleles are numerous, there are no reports for the population of Bosnia and Herzegovina. AIM To estimate the frequency of APOE alleles in a healthy Bosnian population and compare it to data for other European populations. SUBJECTS AND METHODS Overall, 170 unrelated Bosnian subjects (108 female and 62 male), aged 53.0 (±5.0) years were included in this study. Genotypes were determined by real-time PCR. RESULTS In our group the prevalence of heterozygotes E2/E3, E2/E4 and E3/E4 was 20.6%, 3.5% and 12.9%, respectively, while the prevalence of homozygotes E2/E2, E3/E3, E4/E4 was 0.6%, 61.2% and 1.2%, respectively, with a mean frequency of ε2, ε3 and ε4 alleles of 12.6%, 78.0% and 9.4%, respectively. CONCLUSIONS In studied European populations we observed a linear, gradually increasing trend in the frequency of ε4 allele from South to North (Pearson's test 0,7656, p value <0.00001), and the Bosnian population fits into this pattern perfectly.

Abstract
Introduction: Renalase is a protein secreted in kidneys and considered as a blood pressure modulator. High rates of hypertension and its regulation in patients on hemodialysis demands search for potential cause and treatment. The aim of this study was to determine the genotype and allele frequencies of renalase gene rs2576178 polymorphism in population from Bosnia and Herzegovina. Also, the objective of present study was to find the possible association between renalase gene rs2576178 polymorphism and hypertension in patients on hemodialysis. Material and Methods: The genotype of renalase gene rs2576178 polymorphism was determined in 137 participants (100 patients on hemodialysis and 37 controls), using polymerase chain reaction (PCR) and subsequent cleavage with MspI restriction endonuclease. Genotype and allele frequencies were assessed for Hardy-Weinberg equilibrium using a Chi-squared test. The value of P<0.05 was considered as statistically significant. Results: Comparison of genotype distribution and allele frequency in participants on hemodialysis with and without hypertension, and healthy control showed no statistical difference. Conclusion: The results of the study suggest that renalase gene rs2576178 polymorphism is not a factor that influences blood pressure in patients on hemodialysis.

Abstract
Exercise training may increase production of free radicals and reactive oxygen species in different ways. The training type and intensity may influence free radicals production, which leads to differences in oxidative stress status between athletes, but the results of the previous studies are incosistent. The aim of our study was to estimate oxidative stress status in elite athletes engaged in different sport disciplines. The study included 39 male highly skilled professional competitors with international experience (2 Olympic players): 12 wrestlers, 14 soccer players and 13 basketball players in whom we determined the levels of advanced oxidation protein products (AOPP) and malondialdehyde (MDA), as markers of oxidative stress and the total antioxidative capacity (ImAnOX) using commercially available assay kits. The mean AOPP concentration was not significantly different between soccer players, wrestler and basketball players (60.0 ± 23.0 vs. 68.5 ± 30.8 and 80.72 ± 29.1 μmol/L respectively). Mean ImAnOX concentration was not different between soccer players (344.8 ± 35.6 μmol/L), wrestlers (342.5 ± 36.2 μmol/L) and basketball players (347.95 ± 31.3 μmol/L). Mean MDA concentration was significantly higher in basketball players (1912.1 ± 667.7 ng/mL) compared to soccer players (1060.1 ± 391.0 ng/mL, p=0.003). In spite of this fact, oxidative stress markers levels were increased compared to referral values provided by the manufacturer. Type of sports (soccer, wrestler or basketball) have no impact on the levels of oxidative stress markers. Elite sports engagement is a potent stimulus of oxidative stress that leads to the large recruitment of antioxidative defense. Oxidative stress status monitoring followed by appropriate use of antioxidants is recommended as a part of training regime.

Abstract
BACKGROUND Venous thrombosis (VT) affects 1-2 out of 10(3) individuals each year. Mutations of 1691G > A FV gene, 20210G > A PT gene and 677C > T gene MTHFR are common in Europe and increase the risk of venous thrombosis. To the authors' knowledge, this is the first report on the prevalence of these mutations in the general population of Bosnia and Herzegovina. AIM The aim of this study was to simultaneously analyse main VT associated polymorphisms and compare the results with those published for other European populations. DATA SOURCES Electronic databases including Medline and Embase were searched from 1995 to December 2013. SUBJECTS AND METHODS The subjects of the study consisted of 100 unrelated healthy people from Bosnia and Herzegovina (82 female and 18 male). The mean age of the cohort was 58.8 (± 10.7) years. PCR-RFLP was used for measurement of allele frequencies. RESULTS All three SNPs were found to be polymorphic, with allele frequencies of 6.0%, 6.0% and 37.5% for 1691A FV, 20210A PT and 677T MTHFR, respectively. CONCLUSION Further studies on larger cohorts with an adequate female-to-male ratio are necessary to confirm a high prevalence of hereditary thrombophilia in the Bosnian population.

Abstract
Studies that investigated an association between asymmetric dimethylarginine (ADMA) and glycated haemoglobin (HbA1c) in type 2 diabetes mellitus (T2DM) have given discordant results. The aim of this study was to determine and compare serum ADMA concentration in patients with T2DM and healthy controls, and to assess correlation between ADMA and HbA1c in patients with T2DM. Serum ADMA concentration was determined by ELISA method with the use of ADMA ® - ELISA kit (DLD Diagnostics, Hamburg, Germany) and HbA1c levels were determined by an immunoturbidimetric method in 60 patients with T2DM and 60 healthy individuals matched for age and sex. Results have shown that mean serum ADMA concentration was significantly higher in T2DM patients (1.54±0.06 μmol/L) compared to mean serum ADMA concentration (0.62±0.02 μmol/L; p<0.0001) in healthy subjects. A significant, positive, correlation between serum ADMA concentration and HbA1c levels was observed (r=0.494; p<0.01) in T2DM patients. Our results suggest that there is an association between endothelial dysfunction and glycaemic control in type 2 diabetes mellitus. Possible explanation for obtained results may be oxidative stress that is increased in conditions of hyperglycaemia and it also promotes endothelial dysfunction. Larger, longitudinal studies are required that will evaluate relation between metabolic abnormalities and increased ADMA levels in patients with type 2 diabetes mellitus.

Abstract
The aim of the study was to detect prevalence of MBL2 exon 1 (codons 52, 54 and 57) genetic polymorphism in postmenopausal women in Bosnia and Herzegovina and its possible role as genetic risk factor for susceptibility to occurrence of osteoporosis in this study group. Also, we investigated association between MBL serum concentrations and osteoporosis in postmenopausal women. Genetic codons' variations were determined by PCR-RFLP and MBL in serum was measured by ELISA method in 75 postmenopausal women (37 with osteoporosis and 38 apparently healthy, non-osteoporotic women serving as a control). Serum MBL levels were not significantly different between osteoporosis and control group (492 (37-565.1) and 522.6 (477-559.4) ng/mL respectively, p=0.206). Genotype frequencies were not significantly different (p=0.997) between the studied groups of postmenopausal women. Genotype frequencies A/A, A/0 and 0/0 in osteoporosis group were 0.576; 0.405; 0.018 and in control group 0.562; 0.412; 0.026, respectively. Frequencies of A and 0 allele were 0.78 and 0.22 in osteoporosis and 0.77 and 0.23 in control group. The results do not suggest association of functional polymorphism of MBL2 gene and MBL serum concentration with osteoporosis in postmenopausal females.

Abstract
Recent evidence has demonstrated the role of CCR5Δ32 in a variety of human diseases: from infectious and inflammatory diseases to cancer. Several studies have confirmed that genetic variants in chemokine receptor CCR5 gene are correlated with susceptibility and resistance to HIV infection. A 32-nucleotide deletion within the CCR5 reading frame is associated with decreased susceptibility to HIV acquisition and a slower progression to AIDS. Mean frequency of CCR5Δ32 allele in Europe is approximately 10%. The highest allele frequency is observed among Nordic populations (about 12%) and lower in the regions of Southeast Mediterranean (about 5%). Although the frequency of CCR5Δ32 was determined in numerous European populations, there is a lack of studies on this variant in the Bosnia and Hercegovina population. Therefore, the aim of our study was to assess the frequency of CCR5Δ32 allele in the cohort of Bosniaks and compare the results with European reports. CCR5Δ32 was detected by sequence-specific PCR in a sample of 100 healthy subjects from Bosnia and Herzegovina (DNA collected 2011-2013). Mean age of the cohort being 58.8 (± 10.7) years, with 82% of women. We identified 17 heterozygotes and one mutant homozygote in study group, with mean ∆32 allele frequency of 9.5%. CCR5∆32 allele frequency among Bosniaks is comparable to that found in Caucasian populations and follows the pattern of the north-southern gradient observed for Europe. Further studies on larger cohorts with adequate female-to-male ratio are necessary.

Abstract
The utility of procollagen type 1 N-terminal propeptide (P1NP) in the management of metabolic bone diseases remains a subject of debate since the reference ranges are not rigorously established and fail to account for many of the preanalytical variables. We aimed to establish reference intervals for P1NP level in healthy and osteoporotic postmenopausal females stratified by age, body mass index and menopausal duration. We also aimed to assess the relationship between P1NP and BMD. This cross-sectional study enrolled 183 postmenopausal females who were divided in osteoporosis group (N=93) and control group (N=90) with preserved bone mass based on BMD assessed by DXA. In the osteoporosis group median P1NP was significantly higher (51.7 ng / mL; 95%CI 43.2-53.7) compared to control group (38.9 ng/mL; 95%CI 34.2-43.9)(p<0.01). After controlling for age, BMI and years since menopause, there was significant inverse association between BMD and P1NP at the femoral neck (r=-0.18), total hip (r=-0.207) and lumbar spine (r=-0.236). There was no significant difference in P1NP concentration across quartiles of age in postmenopausal females. P1NP was significantly lower in obese postmenopausal females with preserved bone mass compared to normal weight and overweight females in control and in osteoporosis group. In conclusion, we showed that P1NP is inversely associated with BMD even after controlling for age, BMI and years since menopause. Although, P1NP is significantly higher in postmenopausal females with osteoporosis compared to postmenopausal females with preserved bone mass its low specificity does not warrant its utility is diagnosing osteoporosis.

Abstract
OBJECTIVES The purpose of this study was to determine endothelin (ET)-1 and nitric oxide (NO) serum concentration levels at baseline and after 1 year of peritoneal dialysis (PD) treatment. A further aim was to evaluate the association between ET-1 and NO with parameters of echocardiography and the common carotid artery (CCA) ultrasound, and to assess their impact on cardiovascular remodeling. We also aimed to evaluate the influence of dialysis adequacy and residual renal function (RRF) on cardiovascular remodeling. METHODS This study included 40 PD patients in whom we measured serum ET-1 and NO concentrations, echocardiography and CCA ultrasound parameters. RESULTS ET-1 decreased and NO serum concentration levels increased (p < 0.01) after 12 months of PD treatment compared to baseline values. Left ventricular (LV) hypertrophy was observed in 77.5% of patients at baseline with significant reduction in LV mass index (LVMI), CCA intima media thickness (IMT) and plaque score after 12 months of PD treatment (p < 0.001). The dialysis adequacy and RRF were significantly associated with LVMI and CCA IMT after 12 months on PD. CONCLUSION In our study, ET-1 significantly decreased while NO increased during PD treatment and both were independently related to the cardiovascular remodeling parameters in PD patients.

Abstract
Factor V is the liver-synthesized multidomain glycoprotein encoded by a gene localised on chromosome 1q23. The point mutation 1691G>A in this gene results in formation of an altered protein of V Factor resistant to activated protein C (APC) cleavage. This mutation alone is the most frequent cause of inborn thrombophilia and the most widely acknowledged genetic risk factor for venous thrombosis in a Caucasian population. This study was designed to provide the first estimate of the frequency of the allele 1691A FV in the Bosnian female population. The 1691G>A FV mutation was examined by polymerase chain reaction-restriction fragment length polymorphism, in a group of 67 women, mean age of 58.6 years with no history of cardiovascular incident. Our findings revealed an absence of the mutated allele 1691A FV in the studied group. This is the first report on the 1691G>A FV mutation in a population from Bosnia and Herzegovina. Further research is needed to establish prevalence of the mutated allele in the population from Bosnia and Herzegovina.

Abstract
Serum thyreoglobulin (Tg) and whole body scintigraphy (I-131 WBS) have been used to detect recurrent and metastatic thyroid cancers postoperatively. However, discordant results of Tg measurement and 131I WBS have been reported. Negative 131I WBS and a positive Tg test are usually found, but less common occurrence of positive 131I WBS and a negative Tg test has also been demonstrated in a small but significant number of cases. Therefore, the aim of the study was to retrospectively analyse patients with positive 131I WBS after total thyreoidectomy and again 1 year after the radioactive iodine. There were 52 patients included in the study. Four weeks after surgery, during which thyroid hormone treatment was not introduced, each patient received an ablative dose of 131I. The evaluation of the WBS was qualitative and considered positive if thyroid remnant, lymphatic node or metastasis were detected. WBS and serum Tg was measured 12 months after 131I ablation with thyroid hormone suppression. We considered positive any Tg level above the sensitivity values and negative if lower than this level. Tg levels were related to the existence of a positive scan or a negative one. In our 52 WBS positive patients concordant positive Tg levels were observed in 42 patients while in 10 patients we found a negative Tg levels after the surgery. After 1-year follow-up, out of initially 42 concordant patients 8 patients showed remaining concordant positive Tg and WBS values. Discordant results were observed in 13 patients (4 patients were Tg- and WBS+ while 9 patients were Tg+ and WBS-). In the majority of patients (50%) remained with concordant results but changed from Tg+ and WBS+ to Tg- and WBS-. Diagnostic WBS is an additional valuable tool, besides Tg levels, in the follow up of patients after total thyreoidectomy.

Abstract
Endothelial dysfunction is associated with diabetic micro- and macroangiopathy as well as with the decline in creatinine clearance. It has been suggested that endothelial dysfunction presents in patients (pts) on continuous ambulatory peritoneal dialysis (CAPD). The objective of this study was to examine the plasma biomarkers of endothelial dysfunction and their association with IMT of carotid arteries in diabetic and non-diabetic patients on CAPD. This study included 37 CAPD pts (25 with type II diabetes and 12 non-diabetic pts) mean age 59.2 years ± 2.48. Plasma von Willebrand factor (vWF) activity, serum albumin, glucose, total cholesterol, triglycerides and lipoprotein (a) levels, as well as serum level of homocysteine, parathyroid hormone (PTH) in plasma and microalbuminuria was determined. Ultrasound examination of carotid arteries was performed in all patients by measured bilateral intima-media thickness of carotid artery (CIMT). Mean IMT value was significantly higher in type 2 DM patients (0.86 ± 0.04 mm) compared to non-diabetic patients (0.52 ± 0.06 mm) on peritoneal dialysis (p<0.0001). There was also a significant difference in lipids /triglycerides and Lp (a)/, procoagulation (fibrinogen, von Wilebrand factor, factor VIII) and inflammatory markers (CRP) level between type 2 DM and non-diabetic CAPD patients. A stepwise multiple regression analysis revealed that log triglycerides and factor VIII were independent factors for the IMT. The results of this research impose that diabetic type 2 CAPD patients have developed systemic alteration of endothelial function and higher risk of cardiovascular complications compared to non-diabetic CAPD patients.

Abstract
This study investigated whether serum C-reactive protein (CRP) concentration is increased in patients with type 1 diabetes mellitus with a normal body mass index (BMI) and whether BMI, glycated haemoglobin (HbA1c) and CRP are correlated in patients with type 1 diabetes. High-sensitivity CRP was determined by immunonephelometry and HbA1c by an immunoturbidimetric method in 30 patients with type 1 diabetes and 30 healthy individuals matched for age, sex and BMI. Median serum CRP concentration in patients with type 1 diabetes (1.34 mg/L) was significantly higher than healthy individuals (0.2 mg/L; p<0.0001). Positive correlation between CRP and BMI was observed (rho=0.598; p<0.0001), but no significant correlation was observed between CRP and HbA1c (rho=0.285; p=NS) in patients with type 1 diabetes. Increased CRP levels in type 1 diabetes patients do not appear to be associated with glycaemic control, and may reflect low-grade inflammation associated with atherosclerosis, as well as activation of innate immune activity.

Abstract
The advent of multicellular organisms was accompanied by the development of short- and long-range chemical signalling systems, including those provided by the nervous and endocrine systems. In turn, the cells of these two systems have developed mechanisms for interacting with both adjacent and distant cells. With evolution, such mechanisms have diversified to become integrated in a complex regulatory network, whereby individual endocrine and neuro-endocrine cells sense the state of activity of their neighbors and, accordingly, regulate their own level of functioning. A consistent feature of this network is the expression of connexin-made channels between the (neuro)hormone-producing cells of all endocrine glands and secretory regions of the central nervous system so far investigated in vertebrates. This review summarizes the distribution of connexins in the mammalian (neuro)endocrine systems, and what we know about the participation of these proteins on hormone secretion, the life of the producing cells, and the action of (neuro)hormones on specific targets. The data gathered since the last reviews on the topic are summarized, with particular emphasis on the roles of Cx36 in the function of the insulin-producing beta cells of the endocrine pancreas, and of Cx40 in that of the renin-producing juxta-glomerular epithelioid cells of the kidney cortex. This article is part of a Special Issue entitled: The Communicating junctions, composition, structure and characteristics.

Abstract
Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system (CNS). It is characterized by loss of myelin, the fatty tissue that surrounds and protects nerve fibres allowing them to conduct electrical impulses. Recent data indicate that oxidative stress (OS) plays a major role in the pathogenesis of multiple sclerosis (MS). The aim of this study was to estimate level of serum total antioxidative capacity in patients with multiple sclerosis. Our cross-sectional study included 33 patients with MS and 24 age and sex matched control subjects. All our patients had a Poser criteria for definite diagnostic categories of multiple sclerosis. Serum total antioxidant capacity (TAC) was measured by quantitative colorimetric determination, using Total antioxidant Capacity-QuantiCromAntioxidant Assay Kit (BioAssay systems, USA; DTAC-100). Mean serum TAC in multiple sclerosis group of patients was 119.2 mM Trolox equivalents and was significantly lower (p<0.001) compared to the control group of subjects (167.1 mM Trolox equivalents). Our results showed that oxidative stress plays an important role in pathogenesis of multiple sclerosis. This finding, also, suggests the importance of antioxidants in diet and therapy of MS patients.

Abstract
Antiresorptive agents are widely used to treat osteoporosis. Both reduction in bone turnover and increase in BMD may be necessary to decrease the fracture risk. The aim of the study was to evaluate the effects of aledronate on bone turnover markers and bone mineral density in postmenopausal women with osteoporosis. The study involved a group of 56 postmenopausal women with osteoporosis treated with alendronate (70 mg) weekly at the Institute of Nuclear Medicine Clinical Center University of Sarajevo during a 12-months period. Bone mineral density (BMD) at lumbar spine and proximal femur and bone turnover markers (serum β-CrossLaps, urinary N-telopeptides of type I collagen (NTx), total serum alkaline phosphatase (AP) and serum osteocalcin) were measured at baseline and after 12 months of the treatment with aledronate. BMD values significantly increased both at lumbar spine by 13.46% and proximal femur by 21.96% during the study period (-3.12±0.24 vs. -2.7±0.19 and -2.55±0.2 vs. -1.99±0.19 respectively; p<0.001). Bone turnover markers significantly decreased during the study period; C-terminal telopeptides of type I collagen fragment (β-CrossLaps) 49.0% (0.51±0.05 vs.0.26±0.028 ng/mL), NTX 33.4% (48.3±4.9 vs.32.15±3.25 nMBCE/mM Cr), AP 24.3% (81.1±5.2 to 61.43±5.2 IU/L) and serum osteocalcin by 29.7% (34.3±2.65 to 24.1±1.36 ng/mL)(p<0.001). Alendronate treatment increased BMD and reduced the level of bone turnover markers. Therefore, the treatment with aledronate during 12 months period can be recommended in postmenopausal women with osteoporosis.

Abstract
AIM To develop a rat model of myocardial infarction induced by isoproterenol (ISO). We investigated a type of histological myocardial changes and cardiac troponin I (TnI) kinetic. METHODS The study has used adult, male, Wistar strain rats. Rats were distributed in ISO and control groups. Rats treated with ISO were divided into groups according to the time of cTnI and myocardial lesion analyses: ISO I (30'), ISO II (60'), ISO III (120') and ISO IV (240'). We determined cTnI (Life Diagnostics Inc. West Chester PA, USA) in the serum by ELISA method. We performed histological analysis on the specimens of left ventricular wall stained by hematoxillin-eosin (HE) method. RESULTS The first statistically significant rise of cTnI was noted 30 minutes after the ISO administration. There was no statistically significant difference between cTnI mean values among the ISO groups. Observed myocardial histological changes were time dependent. CONCLUSIONS This model can be suitable for cardioprotective and cardiotoxicity supstance investigations followed by cTnI measurement in blood. The similarity between induced myocardial lesion on animal model in our study and human myocardial lesion in ischemia give us sufficient impulse for further preclinical researches of new cardiac markers.

Abstract
AIM To estimate the effects of forced repeated swimming stress on BNP serum levels in rats. METHODS Adult male Wistar rats weighting between 280-330 g were divided into two groups: control group (n = 8) and stress group (n = 8). Rats in the stress group were exposed to forced swimming stress daily, for 7 days. The rats were forced to swim in plastic tanks (90 cm wide, 120 cm deep) containing tap water (temperature ca. 25 degrees C). The depth of water was 40 cm. Duration of each swimming session progressively increased from 10 minutes on the first day to 40 minutes on days 6 and 7. Rats were sacrificed and blood was drawn from abdominal aorta for BNP analysis immediately after the last swimming session. B-type natriuretic serum level was determined by ELISA method using RAT BNP-32 kit (Phoenix Pharmaceutical Inc.). RESULTS There was no statistically significant difference between mean BNP serum level in the stress group after the swimming period (0.81 +/- 0.14 ng/ml) as compared to the unstressed group of rats (0.8 +/- 0.08 ng/ml). After the swimming period mean body weight slightly decreased in the stress group in comparison with values before stress period (296.3 g vs. 272.8 g), but this difference was not statistically significant. The stress period had no influence on food intake in the stress rat group. CONCLUSION The workload consisting of 40-minutes long swimming session is not sufficient to provoke BNP release from myocardium in rats.

Abstract
AIM To assess the association between total homocysteine (tHcy) and traditional and nontraditional risk factors in patients with atherosclerotic vascular disease (ASVD). METHODS This cross-sectional study included 99 ASVD patients and 40 control subjects in whom we determined lipid profile, high sensitivity C-reactive protein (hsCRP), uric acid (UA) and tHcy. RESULTS The median tHcy concentration was significantly higher in ASVD group compared to the controls ((18.7(13.65-24.45) vs. 11.48 (10.03-14.2) micromol/L (p < 0.001)). Mean serum cholesterol, low-density lipoprotein cholesterol levels (LDLc) and atherogenic index were significantly lower, while mean serum UA concentration was significantly higher in hyperhomocysteinemic compared to normohomocysteinemic ASVD patients and control subjects. In hyperhomocysteinemic ASVD patients a significant negative correlation between serum logtHcy and cholesterol (r = -0.32), LDLc (r = -0.24), very-low-density lipoprotein cholesterol (VLDLc) (r = -0.295) and atherogenic index (r = -0.25) was observed. In normo-homocysteinemic ASVD patients serum logtHcy was significantly positively correlated with UA (r = 0.46) and hsCRP (r = 0.383). Multivariate linear regression analysis revealed that serum logtHcy was independently positively associated only with UA in normohomocysteinemic ASVD patients. CONCLUSION The results of our study have shown that the association between tHcy and traditional and non-traditional risk factors depends on tHcy serum level. It was observed a negative association between serum tHcy and lipids in hyperhomocysteinemic ASVD patients. On the other hand, in ASVD patients with serum tHcy levels within the reference range a positive independent association between serum tHcy and UA might reflect an underlying elevated tension of redox stress.

Abstract
The aim of this study was to assess echocardiographic changes in female patients with untreated dysfunctional thyroid states and whether the therapy aimed to normalize the thyroid dysfunction could lead to improvement in cardiac systolic and diastolic function. The study included 90 female subjects who performed control of thyroid hormonal status at the Institute of Nuclear Medicine at the University of Sarajevo Clinics Centre and who previously were untreated for the thyroid functional disorders. The study sample was divided in three groups based on the thyroid hormones levels: a) hyperthyroid group (n= 30) b) hypothyroid group (n=30) and c) euthyroid (control). Echocardiography measurements were performed on commercially available Toshiba, SSH 140. Before the therapy no statistically significant differences in the peak early and late mitral inflow velocities (E/A) values between the study groups was observed, but the mean left ventricular ejection fraction (LVEF) in hypothyroid group was significantly lower (58.30+/-1.05) compared to control (64.96+/-0.71) and hyperthyroid group (64.69+/-1.31) (p<0.001). In hypothyroid group we found significant increase in mean LVEF (58.30+/-1.05 vs. 64.95+/-0.86, p<0.01) and E/A (1.06+/-0.07 vs. 1.17+/-0.08; p=0.01) values after the normalization of thyroid hormone status.Thyroid dysfunctional states were not associated with impaired diastolic function, probably due to the short duration of thyroid dysfunction and timely and successful conversion therapy. Systolic function however was significantly reduced in hypothyroid patients but subsequently improved after the adequate therapy. Early diagnostic approach in patients with thyroid dysfunctional states is important for avoidance of cardiac complications that accompany these disorders.

Abstract
Alzheimer;s disease (AD) is a multifactorial disease but its aetiology and pathophisiology are still not fully understood. Epidemiologic studies examining the association between lipids and dementia have reported conflicting results. High total cholesterol has been associated with both an increased, and decreased, risk of AD and/or vascular dementia (VAD), whereas other studies found no association. The aim of this study was to investigate the serum lipids concentration in patients with probable AD, as well as possible correlation between serum lipids concentrations and cognitive impairment. Our cross-sectional study included 30 patients with probable AD and 30 age and sex matched control subjects. The probable AD was clinically diagnosed by NINCDS-ADRDA criteria. Serum total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and triglyceride (TG) levels were determined at the initial assessment using standard enzymatic colorimetric techniques. Low-density lipoprotein cholesterol (LDL-C) and very low density lipoprotein cholesterol (VLDL-C) levels were calculated. Subjects with probable AD had significantly lower serum TG (p<0,01), TC (p<0,05), LDL-C (p<0,05) and VLDL-C (p<0,01) compared to the control group. We did not observe significant difference in HDL-C level between patients with probable AD and control subjects. Negative, although not significant correlation between TG, TC and VLDL-C and MMSE in patients with AD was observed. In the control group of subjects there was a negative correlation between TC and MMSE but it was not statistically significant (r = -0,28). Further studies are required to explore the possibility for serum lipids to serve as diagnostic and therapeutic markers of AD.

Abstract
The evolution of homocysteine (Hcy) changes after acute myocardial infarction is still not elucidated. Serum Hcy concentration has been shown to increase between acute and convalescent period after myocardial infarction and stroke. Also a decrease in serum Hcy during acute phase was observed. It is still not clear whether the Hcy is a culprit or an innocent bystander in cardiovascular diseases. Addressing the discrepancies in Hcy changes in patients with acute myocardial infarction might give insight in Hcy role in cardiovascular diseases and offer implications both for the clinical interpretation and patients risk stratification. The aim of the study was to evaluate serum Hcy concentration changes during early post myocardial infarction. The study included 55 patients with AMI from the Clinics for Heart Diseases and Rheumatism at University of Sarajevo Clinics Centre. For Hcy analysis blood was collected on day 2 and 5 after the AMI onset. Serum Hcy concentration was determined quantitatively with fluorescent polarisation immunoassay on AxSYM system. Cluster analysis revealed two groups of AMI patients with different trends of serum Hcy changes. Increase in serum Hcy concentration was observed in 33 (60,0%) patients (AMI 1 group), while in 22 (40,0%) patients a decrease was observed (AMI 2 group). On day 2, patients in AMI 2 group had significantly higher mean Hcy concentration compared to AMI 1 group of patients (15,27+/-0,96 and 11,59+/-0,61 micromol/L p<0,05). On day 5, no significant difference in mean Hcy level between AMI 1 and AMI 2 group of patients was observed (14,86+/-1,1 vs. 12,75+/-0,74 micromol/L respectively). Significant differences between AMI 1 and AMI 2 patients were observed in VLDLC levels and CK-MB activity on day 2. Patients in AMI 1 group had significant increase in platelets count from day 2 to day 5 (230,1+/-11,6 vs. 244,2+/-11,0; p<0,05). Our study of serial Hcy changes in patients with AMI revealed two different patterns of Hcy changes in early post infarction period which might reflect two distinct populations of AMI patients. Although further research is necessary, possible explanation for the observed findings could be a different genetic background, vitamin and oxidative status of patients with AMI.

Abstract
We investigated serum concentration of C-reactive protein (CRP) and measures of adiposity in 30 patients with type 2 diabetes mellitus (15 male, 15 female) and 30 age and sex-matched apparently healthy subjects. CRP concentration was determined by laser nephelometry (BN II Analyzer) and CardioPhase high-sensitivity CRP (DADE BEHRING) was used as reagent which consists of polystyrene particles coated with mouse monoclonal antibodies to CRP. Results have shown that serum CRP concentration in patients with type 2 diabetes mellitus was statistically significantly higher compared to control group of healthy subjects (p<0,05). Body mass index (BMI) correlated significantly with serum concentration of CRP in patients with type 2 diabetes mellitus (r=0.614; p<0.001). Statistically significant positive correlation was also found between waist to hip ratio and serum CRP concentration in patients with type 2 diabetes mellitus (r=0.426; p<0.05). Elevated serum CRP concentration in patients with type 2 diabetes mellitus is probably caused by the presence of chronic low-grade inflammation in these patients. It is possible that determined increase of CRP concentration reflects activation of innate immune system components in patients with type 2 diabetes mellitus. Implications of established association between measures of adiposity and serum CRP level in type 2 diabetes mellitus remain unclear.

Abstract
The aim of this study was to investigate the role of inducible nitric oxide synthase (iNOS) in gentamicin-induced acute tubular necrosis in rats using the iNOS inhibitor L-N6-(1-iminoethyl) lysine (L-NIL). Wistar rats, both sexes (n=18), were equally divided into three groups. Gentamicin group received intraperitoneally (i.p.) gentamicin in 0.9 % NaCl at a dose of 80 mg/kg/day for five consecutive days. L-NIL+gentamicin group received L-NIL at a dose of 3 mg/kg i.p. 36, 24 and 12 h before first dose of gentamicin. Control group received 0.9 % NaCl i.p. for five consecutive days at the equal volume as gentamicin group. Griess reaction was used for determination plasma level of NO. Semiquantitative histological analysis was used for the evaluation of kidney damage level. The plasma NO level and the level of kidney damage were statistically higher in gentamicin group in comparison to the control group (p=0.046). Application of L-NIL prior to gentamicin led to certain decrease in the plasma level of NO as well as in the level of kidney damage. Application of L-NIL, prior to gentamicin administration, did not provide complete protective effects of L-NIL on the kidney, which was demonstrated on kidney sections. The lack of anticipated protective effect of L-NIL on kidney tissue might be explained with the fact that we have used L-NIL prior but not during/after gentamicin administration. It would be necessary to examine the effects of L-NIL administration not only before, but as well during and possibly after the administration of gentamicin.

Abstract
Metabolic syndrome is a group of factors which increase the risk for development of diabetes, cardiovascular diseases and includes insulin resistance, abdominal adiposity, hyperlipidemia, hypertension and other disorders. Changes in prothrombotic and proinflammatory markers have been observed. Aim of this study was to asses the concentration of fibrinogen and other humoral markers of metabolic syndrome in type 2 diabetic patients. 77 patients both sexes, age 46-83 years have been included. Based on ATP III criteria patients were divided in two groups. Group I - diabetic patients with metabolic syndrome and Group II - diabetic patients without metabolic syndrome. Each group was divided in two subgroups, males and females. The plasma concentration of fibrinogen and humoral markers of metabolic syndrome (triglycerides, cholesterol and glucose) have been evaluated. There were 49.4% patients out of total who met the criteria for metabolic syndrome. Patients in Group I weight in average more then the patients in Group II. Average systolic and diastolic blood pressure values were in all groups and subgroups higher than recommended. Humoral markers of metabolic syndrome were significantly higher (p<0.05) in Group I (triglycerides 2.7+/-0,2 mmol/L, total cholesterol 6.0+/-0.2 mmol/L) compared to Group II (triglycerides up to 1,7 mmol/L, total cholesterol in serum up to 5,2 mmol/L ). Concentration of glucose in both groups was significantly higher compared to referral values. Average plasma fibrinogen concentration was 4.0+/-0.1 g/Lwithout significant differences between Group I and II. Females from Group I had significantly higher fibrinogen concentration (p=0.003) then the males from the same group (females 4.4+/-0.2 g/L vs. males 3.7+/-0.1 g/L). There was no difference in fibrinogen concentration between female and male patients in Group II. Fibrinogen plasma concentration is elevated in all type 2 diabetic patients without significant differences between subjects with or without metabolic syndrome.
