Tartary buckwheat and common buckwheat plants were grown on the field in natural conditions at high elevation. Tartary buckwheat plants were foliarly treated with Se and S (126 μM for each element). Seeds were collected and sown to obtain the progeny of Se-and S- treated plants. Concentration of Se was measured in these plants. Concentration of Se in all plant parts was similar in control and S treated plants. The concentration of Se was the highest in plants from seeds grown on Se treated plants in roots and leaves. It is shown that Se treatments in previous generation affected Se concentration in the progeny of Tartary buckwheat. Results also showed that in untreated plants, Se concentration was higher in Tartary comparing to common buckwheat in roots and seeds.  Key words: Tartary buckwheat, selenium, sulphur Navadna in tatarska ajda sta uspevali na njivi na visoki nadmorski visini. Tatarsko ajdo smo listno skropili s selenom in žveplom (126 μM za vsak element). Na koncu rastne sezone smo na rastlinah zbrali semena in jih naslednje leto posejali. Na ta nacin smo dobili potomce s Se in S obravnavanih rastlin. V teh rastlinah smo merili koncentracijo Se. Koncentracija Se pri tatarski ajdi je bila v vseh rastlinskih delih podobna pri kontrolnih rastlinah in rastlinah, zrastlih iz semen, obravanavanih s S. Najvisjo koncentracijo Se v listih in koreninah so imele rastline, zrasle iz semen, nabranih na rastlinah, listno skropljenih s Se. Rezultati kažejo, da se obravnavanje s Se v prvi generaciji izrazi v vecji koncentraciji Se v potomkah teh rastlin pri tatarski ajdi. Izsledki raziskav so prav tako pokazali, da je koncentracija Se v kontrolnih rastlinah v koreninah in semenih visja pri tatarski ajdi v primerjavi z navadno ajdo.  Kljucne besede: tatarska ajda, selen, žveplo

Introduction: Various risk factors contribute to the occurrence of acute myocardial infarction as the most serious type of ischemic heart disease and the leading cause of sudden death worldwide. Aim of the Study: The aim of this study was to assess the frequency of changeable and unchangeable risk factors in patients with acute myocardial infarction in the Republic of Srpska. Patients and Methods: This cross-sectional study included patients treated for acute myocardial infarction at the University Clinical Center of Banja Luka, in the period from January 1st to December 31st, 2011. The patients were from the municipalities of Banja Luka and Laktaši. We analyzed the following risk factors: hypertension, total cholesterol values, diabetes, increased body weight and obesity, smoking, family history and physical inactivity. Results: Out of 273 patients, the majority were male (64%), and there was a statistically significant difference between age and sex (p <0.01) of the respondents. The most common risk factor for both genders was hypertension (70.1%), while the least frequent risk factor was diabetes mellitus (25.6%). Smokers and ex-smokers accounted for 58.1%, with a statistical significance between men and women (p <0.01). The average BMI in both genders was in the overweight category (27.69 kg / m2). A positive family history was found in almost half of the respondents (49.4%), with a statistically significant difference between age groups and family history (p = 0.036). Conclusion: Acute myocardial infarction mainly affects men in their sixties, while women are averagely affected nine years later than men. The number one risk factor for both genders is hypertension. Given the large impact of risk factors on the occurrence of acute myocardial infarction, priority must be given to the prevention and control of the aforementioned, especially in the primary health care.

, ABSTRACT Introduction: Traumatic flail chest is segment of the chest wall, which is caused by multiple fractures or by separation of bone structures (at least three sequential broken ribs or separated into two fracture lines). These injuries are mainly seen in polytrauma patients. Aim of the Study: Our aim is to show the therapeutic benefits of surgical treatment (operative stabilization) of the flail chest. Patients and Methods: We retrospectively analyzed patients who underwent surgery at the Clinic of Thoracic Surgery, University Clinical Centre of the Republic of Srpska, Banja Luka, in the period from 01. 12. 1997 - 04. 06. 2016. Results: 50 patients with traumatic flail chest with average age of 47.42 years were surgically treated in the twenty-year period at the Clinic of Thoracic Surgery, University Clinical Centre of the Republic of Srpska, Banja Luka. The average length of a hospital stay was 15 days. Survival rate in the operated group was 91.43%. Conclusion: If conservative measures such as internal stabilization, the use of analgesics, antibiotics, oxygen therapy and airway toilet does not lead to stabilization of respiratory function, surgical chest wall stabilization is necessary.

Introduction: Spinal column represents a strong and flexible body axis. It is consisted of vertebrae which are connected by the intervertebral disk and solid fibrous joints. Aim of the Study: To ascertain whether or not and to what extent foraminotomy affects the final outcome of lumbar herniated disc surgery. Patients and Methods: This retrospective study analyzed 71 patients who were operated at the Clinic of Neurosurgery in Banja Luka, in the period from 2009 to 2016. Extirpation of disc was performed in 41 respondents, while in 30 patients, a nerve root was further alleviated, along with the extirpation of disc. All patients were operated under the same conditions. Results: There was no statistically significant difference in the age of women and men who underwent classical discectomy and foraminotomy. There was a statistically significant difference in the disc protrusion and extrusion in patients who underwent conventional discectomy and those who underwent foraminotomy, along with conventional discectomy. There was no statistically significant difference in diagnosis in respondents who underwent conventional discectomy and those who underwent foraminotomy, along with conventional discectomy. There was statistically significant difference in the severity of pain in patients who underwent conventional discectomy and those who underwent foraminotomy, along with conventional discectomy. There was a statistically significant difference in clinical recovery, where the findings were in favor of the respondents who underwent foraminotomy, compared to the respondents who did not. Discussion: The treatment of this syndrome is complex, multidisciplinary and with problematic success, and in cases when the operation is performed, the results are not as good as in the primary operation. Conclusion: The results of this study show that the patients who underwent foraminotomy during the operation of prolapsed lumbar disc have a clinically better result.

Introduction: Drug-induced liver injury (DILI) is a rare but potentially life threatening adverse drug reactions. DILI may mimic pathophysiology or histopathologic features of an acute or chronic liver disease, and they may be indistinguishable from those of other causes of liver injuries. Liver can be affected directly, in a dose-dependent manner, or idiosyncratically, independently of the dose, and therefore unpredictably developed. Methods: In this special article we provided results given in the articles published in PubMed in the period 2006-2016. The search was made based on the most frequent reported drugs inducing liver injuries, diagnostic assessment, monitoring and outcomes of DILI. Results: The true incidence of DILI still remains unknown but the incidence of up to 14 cases per 100,000 inhabitants/year has been most frequently reported. Antimicrobial agents, analgesics, hipolipemics and antiepileptics are the most common drugs causing DILI. Conclusion: Although several biomarkers have been found through analytical tests, none of them have been able to display enough specificity and sensitivity in DILI diagnosis. Therefore, diagnostic assessment of DILI is still based on clinical examination, pharmacological treatment history, current RUCAM criteria, and liver function laboratory test.

Introduction: Controlling the presence of contaminants or harmful substances in milk and dairy products provides early detection of risks since their presence, even in legally permitted concentration, increases the risk of damaging human health, especially children's health, such as allergic manifestations, and they can have potentially toxic, carcinogenic and genotoxic effects. Aim of the Study: The aim is to determine the frequency of the presence of contaminants in samples of milk and dairy products in the Republic of Srpska from 2010 to 2012 (metals, radionuclides, aflatoxins and residues of antibiotics and pesticides), and especially to point out their public health significance because of possible health risks. The aim of the paper is to emphasize the need for monitoring all the other contaminants in milk and dairy products specified in regulations. Material and Methods: The frequency of the presence of contaminants in the samples of milk and dairy products (n= 407) was determined on the basis of legally prescribed methodology of sampling, chemical analyses and preparation of expert opinion on food safety in accordance with current food regulations. Descriptive statistical indicators were used (a number of the samples, minimum and maximum concentrations). Chi square test (χ2) of contingency was used for testing the significance of differences in presence of contaminants and residues analyzed and recommended by regulations in samples of milk and dairy products. Results: The results of public health research of contaminants in samples of milk and dairy products indicate that no health defective food samples were determined at tested parameters - metals, radionuclides, aflatoxins, and residues of antibiotics and pesticides. A statistically significant number of samples examined on heavy metal content (83.29% or 339 samples) was determined comparing to the number of samples examined on the other contaminants and residues recommended by regulations in milk and dairy products (χ2=1000.776, p<0.001) Conclusion: The data obtained can serve as a basis for further analysis in the context of milk and dairy product sample monitoring. Although samples of milk and dairy products are safe, a long-term exposure to residues of harmful substances results in cumulative effect and damage health, meaning that each early detection of food risk found through continuous controls has a public health significance for preservation and promotion of population health in the Republic of Srpska.

We present a calculation of the lattice thermal conductivity of Si-Ge nanowires (NWs), based on solving the Boltzmann transport equation by the Monte Carlo method of sampling the phonon mean free paths. We augment the previous work with the full phonon dispersion and a partially diffuse momentum-dependent specularity model for boundary roughness scattering. We find that phonon flights are comprised of a mix of long free flights over several $\ensuremath{\mu}\mathrm{m}$ interrupted by bursts of short flights, resulting in a heavy-tailed distribution of flight lengths, typically encountered in L\'evy walk dynamics. Consequently, phonon transport in Si-Ge NWs is neither entirely ballistic nor diffusive; instead, it falls into an intermediate regime called superdiffusion where thermal conductivity scales with the length of the NW as $\ensuremath{\kappa}\ensuremath{\propto}{L}^{\ensuremath{\alpha}}$ with the exponent of length dependence $\ensuremath{\alpha}\ensuremath{\approx}0.33$ over a broad range of wire lengths $10\phantom{\rule{4pt}{0ex}}\mathrm{nm}lLl10\phantom{\rule{4pt}{0ex}}\ensuremath{\mu}\mathrm{m}$ regardless of diameter and roughness. We conclude that thermal conductivity in Si-Ge alloy NWs is length dependent up to $10 \ensuremath{\mu}\mathrm{m}$ and therefore can be tuned for thermoelectric applications.

The objective of this paper is to present new and simple mathematical approach to deal with uncertainty transformation for fuzzy to random or random to fuzzy data. In particular we present a method to describe fuzzy (possibilistic) distribution in terms of a pair (or more) of related random (probabilistic) events, both fixed and variable. Our approach uses basic properties of both fuzzy and random distributions, and it assumes data is both possibilistic and probabilistic. We show that the data fuzziness can be viewed as a non uniqueness of related random events, and prove our Uncertainty Balance Principle. We also show how Zadeh’s fuzzy-random Consistency Principle can be given precise mathematical meaning. Various types of fuzzy distributions are examined and several numerical examples presented.
