Introduction: Colorectal cancer is the third most common tumor which causes high percentage of mortality in the general population. Etiologic factors which cause this disease are various, while diagnostic methods involve very complex protocols from detection of tumor markers to a combination of endoscopic and imaging methods. Goal: To determine the number of patients suffering from colon cancer for a period of two years and with endoscopic methods to verify and localize the tumor and its spread. Histopathological determination of the tumor type. Determine the concentration of CEA and CA 19-9 in the serum. Depending on the tumor location asses its progression, severity and extent by radiological imaging methods. Material and Methods: The study was prospective and retrospective, performed at the Gastroenterohepatology Clinic of the Clinical Center of Sarajevo University. During the two-year follow-up, 91 patients were hospitalized underwent endoscopy, targeted biopsy and histologically proven adenocarcinoma of the colon in which a pathologist determined grade of the cancers. Samples were eosin stained and underwent pathological histological analyzes. All patients according to tumor localization underwent CT scan and MRI of the rectum and pelvis. Results: The most common location of the cancer regardless of sex was in the recto sigmoid colon. Prevalence of colorectal cancer spread to other organs was not related to location. No significant dependence of the localization of the tumor by gender was found (p-value = 0.313). Ca 19-9 had the highest value in localization of tumors in the rectum. There was no statistically significant difference in age between men and women. The largest number of patients has adenocarcinoma grade 2 and the localization at the rectum. Conclusion: The combination of laboratory parameters (CEA and CA 19-9) with endoscopic and radiological imaging methods is essential in diagnosis of colorectal cancer and assessment of the process progression. There is a need to impose additional diagnostic parameters to detect the disease at an earlier stage.

The purpose of this study was to identify the effects of warm-up strategies on countermovement jump performance. Twenty-nine male college football players (age: 19.4 ± 1.1 years; body height: 179.0 ± 5.1 cm; body mass: 73.1 ± 8.0 kg; % body fat: 11.1 ± 2.7) from the Tuzla University underwent a control (no warm-up) and different warm-up conditions: 1. general warm-up; 2. general warm-up with dynamic stretching; 3. general warm-up, dynamic stretching and passive stretching; 4. passive static stretching; 5. passive static stretching and general warm-up; and, 6. passive static stretching, general warm-up and dynamic stretching. Countermovement jump performance was measured after each intervention or control. Results from one way repeated measures ANOVA revealed a significant difference on warm-up strategies at F (4.07, 113.86) = 69.56, p < 0.001, eta squared = 0.72. Bonferonni post hoc revealed that a general warm-up and a general warm-up with dynamic stretching posted the greatest gains among all interventions. On the other hand, no warm-up and passive static stretching displayed the least results in countermovement jump performance. In conclusion, countermovement jump performance preceded by a general warmup or a general warm-up with dynamic stretching posted superior gains in countermovement jump performance.

Perforation of the colonic diverticulum is a common reason for emergency laparotomy, especially in older people but is rare in the younger population. While perforation of the sigmoid diverticulum is very common, perforation of the ascending colonic diverticulum is a very rare event. For this reason, the divereticulitis is usually discovered unexpectedly at surgery for suspected appendicitis.

UDK 582.711.714:577.164.2           543.42:577.164.2 Vitamin C or ascorbic acid content has been determinated by spectrophotometric method and titrimetric method in flowers of some Bosnian hawthorns (Crataegus L). species. Spectrophotometric method used in this study was based on the kinetic reaction between Vitamin C and methylene blue. Measurements were carried out at absorption maximum, λmax= 665 nm. We found that the lowest content of vitamin C was 617.07 mg/100 g of dry sample in flowers of the C. microphylla, and the highest level of Vitamin C was found in the C. monogyna (1104 mg/100 g of dry sample) flowers. Recoveries of the results obtained by the spectrophotometric method were 94 % - 100% with relative standard deviation (RSD) values from 4.5% – 6.7 %. Obtained results shown that flowers of investigated Crataegus L. species are good source of vitamin C.

Scientific publishing is the ultimate product of scientist work. Number of publications and their quoting are measures of scientist success while unpublished researches are invisible to the scientific community, and as such nonexistent. Researchers in their work rely on their predecessors, while the extent of use of one scientist work, as a source for the work of other authors is the verification of its contributions to the growth of human knowledge. If the author has published an article in a scientific journal it cannot publish the article in any other journal h with a few minor adjustments or without quoting parts of the first article, which are used in another article. Copyright infringement occurs when the author of a new article with or without the mentioning the author used substantial portions of previously published articles, including tables and figures. Scientific institutions and universities should,in accordance with the principles of Good Scientific Practice (GSP) and Good Laboratory Practices (GLP) have a center for monitoring,security, promotion and development of quality research. Establish rules and compliance to rules of good scientific practice are the obligations of each research institutions,universities and every individual-researchers,regardless of which area of science is investigated. In this way, internal quality control ensures that a research institution such as a university, assume responsibility for creating an environment that promotes standards of excellence, intellectual honesty and legality. Although the truth should be the aim of scientific research, it is not guiding fact for all scientists. The best way to reach the truth in its study and to avoid the methodological and ethical mistakes is to consistently apply scientific methods and ethical standards in research. Although variously defined plagiarism is basically intended to deceive the reader’s own scientific contribution. There is no general regulation of control of scientific research and intellectual honesty of researchers which would be absolutely applicable in all situations and in all research institutions. A special form of plagiarism is self-plagiarism. Scientists need to take into consideration this form of plagiarism, though for now there is an attitude as much as their own words can be used without the word about plagiarism. If the authors cite their own research facilities already stated then they should be put in quote sand cite the source in which it was published. Science should not be exempt from disclosure and sanctioning plagiarism. In the fight against intellectual dishonesty on ethics education in science has a significant place. A general understanding of ethics in scientific research work in all its stages had to be acquired during the undergraduate course and continue to intensify. It is also important ethical aspect of the publishing industry,especially in small and developing economies,because the issuer has an educational role in the development of the scientific community that aspires to relish so. In this paper author describe his experiences in discovering of plagiarism as Editor-in-Chief of three indexed medical journals with presentations of several examples of plagiarism recorded in countries in Southeastern Europe.

Due to demographic change, more elderly people have the need to preserve and support mobility by car despite age-related functional limitations. Since accidents by the elderly are primarily caused by age related limitations, and not by careless or irresponsible behavior, it may be beneficial to detect driving impairing conditions. The presented review gives an overview of technologies to detect driving impairing conditions like drowsiness and stress or excessive demand. A comparison of the approaches to detect these conditions suggests that a combination of approaches is the most feasible method. However, there are still few systems that focus on the elderly.

Aim To describe characteristics and outcome of mechanically ventilated patients admitted to three newly established intensive care units (ICU) in Bosnia-Herzegovina and Serbia for 2009 H1N1 influenza infection. Methods The retrospective observational study included all mechanically ventilated adult patients of three university-affiliated hospitals between November 1, 2009 and March 1 2010 who had 2009 H1N1 influenza infection confirmed by real-time reverse transcriptase-polymerase-chain-reaction (RT-PCR) from nasopharyngeal swab specimens and respiratory secretions. Results The study included 50 patients, 31 male (62%), aged 43 ± 13 years. Median time from hospital to ICU admission was 1 day (range 1-2). Sixteen patients (30%) presented with one or more chronic medical condition: 8 (16%) with chronic lung disease, 5 (10%) with chronic heart failure, and 3 (6%) with diabetes mellitus. Thirty-two (64%) were obese. Forty-eight patients (96%) experienced acute respiratory distress syndrome (ARDS), 28 (56%) septic shock, and 27 (54%) multiorgan failure. Forty-five patients (90%) were intubated and mechanically ventilated, 5 received non-invasive mechanical ventilation, 7 (14%) high-frequency oscillatory ventilation, and 7 (14%) renal replacement therapy. The median duration of mechanical ventilation was 7 (4-14) days. Hospital mortality was 52%.

UDK 595.384.1:591.134(282.249 Neretva) Specimens of white-clawed crayfish have been cought during from May to August 2011. The specimens were fished out from the tributaries of the river Neretva: Neretvica, Sistica and Kraljuscica. The study was done on 100 m of waterstream, where an unequal numbers of individuals was determined. 31 individuals was found in river Neretvica, 10 individuals in river Sistica and 4 in river Kraljuscica. Different hydromorphological characteristics of the waterstream have largely contributed to the different population abundance of this crayfish. Morphometric analysis included six parameters: (TL) total length [cm], (W) weight (gr), (ARL) carapace length [cm], (CPW) carapace width [cm], (ROL) rostrum length [cm], (ROW) rostrum width [cm], (CLL) claws length [cm] and (TEL) tail length [cm]. Total body length of the white- clawed crayfish varied from 4.3 to 8. 6cm, while the individual with maximum length was found in river Neretvica. Weight of the individuals varied from 5g to 26g. Weight is the parameter with the highest coefficient of variation where differences in weight were found in the individuals of equal length. According to the shape (length and width) of the rostrum, crayfish from river Neretvica and Kraljuscica had higher similarity than recripocally than with the individuals cought in river Sistica (isosceles triangle). The connection between body length and carapax width had been determined by linear regression, as well as the connection between body length and claws length. Condition index values are higher in males than in females and the male domination was express in all three watercourses, as well as in the overall sample (28males and 17 females).

Sažetak Glavna uloga uzemljenja jeste da odvede struje kvara u zemlju, te da unutar elektroenergetskog postrojenja obezbijedi sigurnost osoblju i opremi za vrijeme kvarova u sistemu. Odvođenje struje sa uzemljivača rezultira nastankom strujnog polja u njegovoj blizini. Postavljanje podzemnih metalnih objekata u zoni utjecaja strujnog polja uzemljivača po pravilu dovodi do iznošenja potencijala. U radu je sa posebnom pažnjom analizirana problematika iznošenja potencijala preko čeličnih cjevovoda koji su ukopani u blizini uzemljivača trafostanica. Analize su provedene na primjerima jednoslojnog i dvoslojnog tla.
