Objective: Stem cells could be defined as cell with an extraordinary capacity for self-renewal and the ability to differentiate into different cell types. The aim of this study is to examine students' opinion about the use of stem cells as health technologies in disease treatment and radical life extension. Method: Prospective cross-sectional study was conducted as a questionnaire, which was filled anonimly and voluntarily. Results: In this study 655 respondents have participated, with an average age 21.9±}1.8 years. High percentage distribution was concluded with most of the statements, with especially positive attitude towards the preservation of stem cells for their own treatment (84.2%), and treatment of their families (85.4%). Dominantly neutral attitude was expressed according to a statement about the reliability of stem cells and doubts about their implementation.(49.4%).There was no statistically significant difference in students' opinion between different faculties. Conclusion: It is important to evaluate students' opinion because it can obtain information on how the respondents agree with the potential implementation of health technology in the future and, accordingly, whether it is justified to continue further research. We should be more dedicated to informing students in the future, and this type of research should be implemented on a wider population to obtain the relevant results and perform more reliable conclusion.

The aim of the study was to determine the presence of risk factors for developing hypertension in the University of Belgrade student population whose faculties do not provide the opportunity to learn about these factors. A cross-sectional study was conducted during November and December 2015 at the Faculty of Mechanical Engineering, the Faculty of Electric Engineering and the Faculty of Law. The respondents filled in a questionnaire, which was approved by the Ethics Committee for bio-medical research from the Faculty of Pharmacy. The study included 487 students. 56.7% were male students. Most of the respondents studied Law (210), followed by Mechanical Engineering (168) and Electrical Engineering (109). 75.8% of respondents consumed salty snacks, while 34.5% of them changed their habits of consuming snacks during the examination period. Fish was consumed less than once a week by 39.8% of the respondents, whereas 19.9% of them consumed candies every day. 63.9% consumed fast food. Energy drinks were not consumed by the majority (52.2%), while 22.4% only consumed them before an exam. The research results indicated the presence of reversible risk factors in the examined student population. In order to prevent the development of hypertension in the elderly population and reduce the number of risk factors present, it is necessary to develop educational programs for proper diet and adequate intake of food groups.

By using the methods of multi-criteria analysis it is possible to make decisions which have significant influence on companies' business. The aim of this paper is to evaluate different suppliers using the integrated model that recognizes a combination of fuzzy AHP (Analytical Hierarchy Process) and the COPRAS method. Based on six criteria, the expert team was formed to compare them, so determination of their significance is being done with fuzzy AHP method. Expert team also compares suppliers according to each criterion and on the base of triangular fuzzy numbers. Based on their inputs, COPRAS method is used to estimate potential solutions. Suggested model accomplishes certain advantages in comparison with previously used traditional models which were used to make decisions about evaluation and choice of supplier. It is vital to make the right decision when selecting a supplier, because the optimal choice ensures lower cost and higher quality of the product itself, and therefore more competitiveness in the market.

The aim of this study was to determine the distribution of κ-casein (κ-CN) and β-lactoglobulin (β-Lg) genotypes in the autochtonous (Busha) and dairy (Holstein-Friesian, HF) cattle breeds with PCR-RFLP (polymerase chain reaction restriction fragment length polymorphism). For the amplification of κ-CN and β-Lg gene fragments specific primers were used. After digestion with specific endonucleases genotypes were determined for both genes in 18 Busha and 19 HF cows. The results showed that κ-CN gene was represented with the AA genotype in 31.58 % HF cows, AB in 52.63 % cows, whilst the genotype BB was found in 15.79 % cows only. Among the examined Busha cattle 44.44 % cows had AA genotype and 55.56 % genotype AB for κ-CN. As for β-Lg gene in HF breed, AA genotype was found in 26.31 % cows, AB in 63.16 % and BB in 10.53 % cows. In Busha cows the following genotypes were established for β-Lg gene: AA in 44.44 % cows and AB in 55.56 %, whilst BB genotype was not found. These results indicate that Busha cows had a higher presence of A allelic forms of both genes (k-CN and β-lactoglobulin) than HF cows.

INTRODUCTION Turner syndrome is a chromosomal abnormality where all or a part of one of the X chromosomes is absent or it has other abnormalities. Besides characteristic abnormalities of short stature and infertility, women with Turner syndrome have increased risks for tumors of the central nervous system, especially meningioma and an otologic disease. Meningioma involving the middle ear is extremely rare, and this condition has never been published in association with Turner syndrome. CASE REPORT We present an otologic manifestation associated with other abnormalities in a patient with Turner syndrome and discuss diagnosis and possible treatment options. CONCLUSION Multidisciplinary team approach is essential in these patients in order to evaluate their vulnerability and define therapeutic priorities.

Summary Introduction. Turner syndrome is a chromosomal abnormality where all or a part of one of the X chromosomes is absent or it has other abnormalities. Besides characteristic abnormalities of short stature and infertility, women with Turner syndrome have increased risks for tumors of the central nervous system, espe- cially meningioma and an otologic disease. Meningioma involv- ing the middle ear is extremely rare, and this condition has never been published in association with Turner syndrome. Case Report. We present an otologic manifestation associated with other abnormalities in a patient with Turner syndrome and discuss diagnosis and possible treatment options. Conclusion. Multidis- ciplinary team approach is essential in these patients in order to

One of the most important health problems of today's society is hypokinesia accompanied by obesity. The assumption is that reduced physical activity has a large negative impact on the school population. The problem of reduced commitment and involvement of pupils in extracurricular activities is increasingly evident in recent times, which results in a number of negative health effects on the human body of an individual. This study comprised a group of older school children from first to fourth year of high school in Pale. The total sample consisted of 127 female pupils aged 15 to 18 years. As a way of gathering the required information we used an anonymous questionnaire of open type in order to collect information about student involvement in extracurricular sports activities. The survey was conducted in November 2012 and all the pupils voluntarily participated in the study. Based on the survey results have been obtained the necessary information to reflect the relative lack of physical activity, of the studied population. Of the total sample of female pupils, the survey confirmed that only about 22% are physically active pupils. The alarming are the results which showed that with the increasing age of pupils they are less physically active, and in the higher years is evident negative trend in physical activity (sports).
