Vitamin C (ascorbic acid) is a water-soluble vitamin and essential for collagen, carnitine and neurotransmitter biosynthesis. Naproxen sodium is propionic acid derivative and anti-inflammatory non-steroid agent. The aim of the study was to assess genotoxicity of selected medicaments and their possible effects on genetic material using Allium bioassay. The treatment of onion bulbs with fresh solutions of Naproxen Sodium (Nalgesin S®) and Vitamin C was performed using selected concentrations (550, 825 µg/ml and 250, 500, 1000 µg/ml respectively) in 72 hours time period. Control group was also set up.The microscopic parameters (mitotic index and chromosomal aberrations) of Allium root tips as well as the frequency of aberrant mitotic phases were analyzed. Both medicaments (vitamin C and Naproxen Sodium) caused increased frequency of abnormal mitosis when compared to control group.

We investigate the global character of the difference equation of the form xn+1=f(xn,xn−1),n=0,1,…\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$x_{n+1} = f(x_{n}, x_{n-1}),\quad n=0,1, \ldots $$\end{document} with several period-two solutions, where f is increasing in all its variables. We show that the boundaries of the basins of attractions of different locally asymptotically stable equilibrium solutions or period-two solutions are in fact the global stable manifolds of neighboring saddle or non-hyperbolic equilibrium solutions or period-two solutions. As an application of our results we give the global dynamics of three feasible models in population dynamics which includes the nonlinearity of Beverton-Holt and sigmoid Beverton-Holt types.

The primary aim of this article is to identify antecedents of firm's success in specific circumstances of the New economy. Many researchers have tried to answer the question "Why do some firms persistently outperform others?". One of the most dominant view on this issue is a resource based view (RBV) or resource-based theory (RBT). According to this theory, sources of competitive advantage begin with the notion that differences in performance are fundamentally due to the distinctive resources and capabilities that are valuable, rare, inimitable and non-substitutable. Information technology as a resource of the company has the increasing importance for the researches and managers. Research on the information technology (IT) value within organizations and firms' IT capabilities have expanded over the past decade. IT capability is defined as the existence of IT infrastructure, IT knowledge and IT operations within company. The purpose of this paper is to analyse the interaction impact of IT capability and firms' innovation on business performance. The study uses survey data from managers and structural equation modelling to assess the relationships between IT capability, firm's innovation and business performance. This study finds that both IT capability and innovation capability play important role in achieving greater business performance. The findings indicate that managers should focus on development of the IT function within company, taking into account importance of IT investment as well as IT knowledge, and promotion of innovativeness.

Gastroschisis is an isolated structural anomaly rarely associated with other life-threatening anomalies. The most common associated gastrointestinal anomalies are intestinal atresia, Meckel's diverticulum and intestinal duplications. Intestinal atresia occurs in 10-15% of gastroschisis cases. [1] We herein report a case of gastroschisis with concomitant type III b jejuno-ileal atresia with perforation of the proximal dilated segment of jejunum with congenital short bowel successfully treated by primary anastomosis and primary abdominal closure.

BackgroundFunctional transcanial Doppler ultrasound (fTCD) is a convenient approach to examine cerebral blood flow velocity (CBFV) in major cerebral arteries.MethodsIn this study, the anterior cerebral artery (ACA) was insonated on both sides, that is, right ACA (R-ACA) and left ACA (L-ACA). The envelope signals (the maximum velocity) and the raw signals were analyzed during cognitive processes, i.e. word-generation tasks, geometric tasks and resting state periods separating each task. Data which were collected from 20 healthy participants were used to investigate the changes and the hemispheric functioning while performing cognitive tasks. Signal characteristics were analyzed in time domain, frequency domain and time-frequency domain.ResultsSignificant results have been obtained through the use of both classic/modern methods (i.e. envelope/raw, time and frequency/information-theoretic and time-frequency domains). The frequency features extracted from the raw signals highlighted sex effects on cerebral blood flow which revealed distinct brain response during each process and during resting periods. In the time-frequency analysis, the distribution of wavelet energies on the envelope signals moved around the low frequencies during mental processes and did not experience any lateralization during cognitive tasks.ConclusionsEven if no lateralization effects were noticed during resting-state, verbal and geometric tasks, understanding CBFV in ACA during cognitive tasks could complement information extracted from cerebral blood flow in middle cerebral arteries during similar cognitive tasks (i.e. sex effects).

The rapid advancements in information and communications technologies (ICT) and the increasing number of smart things shift an old-fashioned healthcare system to a model better suited for a population of the 21st century. New healthcare approaches based on Internet of Things (IoT)/Internet of Medical Things (IoMT) powered systems make health monitoring, diagnostics and treatment more personalized, timely and convenient, enabling a global approach to the healthcare system infrastructure development. Commercial systems in this area exist in various forms but usually do not fit the general patient needs, and those that do are usually economically unacceptable due to the high operational and development costs. Do It Yourself (DIY) healthcare, including mobile applications and consumer medical devices, nowadays is the top healthcare trend. Therefore, this paper, based on well-known low-cost technologies, presents a DIY IoMT solution for observing human vital parameter as well as environmental factors affecting health.

In addition to analysing the constitutional and normative framework of local self-government in Bosnia and Herzegovina, the paper aims to establish normative and other shortcomings of the existing system of local self-government. It also offers proposals for improving its efficiency and quality, bringing it in line with the best existing European practices. The paper presents and critically assesses the status of local self-government in the three constitutional units of Bosnia and Herzegovina, namely the Federation of Bosnia and Herzegovina, the Srpska Republic, and the Brčko District.

Introduction: The aim of this paper was to evaluate the managerial knowledge and skills of mid-level managers – medical doctors in Medical center of the Canton Sarajevo.Methods: A cross-sectional study of the mid-level managers in the Medical center of the Canton Sarajevo was conducted using an originally developed questionnaire for self-assessment of managerial knowledge and skills. The respondents answered each of the questions using a 5-point Likert scale. Apart from the quantitative section, the respondents could present their observations concerning the educational needs in the health care system.Results: Almost 40% of the respondents said that the process of assessing health care needs is not conducted. No statistical significance was observed in the responses according to the length of service in a managerial position. In total, 41% of the respondents were not sure whether a plan exists, even though the development of these plans should be a principal managerial responsibility in the quality management. Managers who were longer in the position reported no plans for corrective actions. This result was in contrast with the answers obtained from the managers who were in the position for a shorter period. In addition, 91% of the respondents said that they regularly discuss problems with their employees.Conclusions: Self- assessment and assessment of managerial competencies should be regular activities in a health care organization, in order to monitor the knowledge and skills, as well as to make the development plans. The results of this study could serve as the basis for planning and developing the health management education in the Canton Sarajevo.

Invasive breast cancer is a heterogeneous disease. The analysis of one or a group of specific gene expression profiles may not be enough to understand molecular activities in cancer cells. Therefore, a method which gives us the opportunity to compare similar up and down regulated gene expression profiles, is needed. The main purpose of our work is to sort the extreme high and low expressed genes and extract, compare and cluster them. Expression profiles of 598 samples of invasive breast cancer and 48 samples of normal tissue have been analysed to create a new algorithm called Extreme Gene Expression Family (EGEF). The EGEF algorithm sorted, grouped and compared the highest and the lowest expressed genes (n = 100). According to the hierarchical clustering result, dense and light memberships of gene families are detected. The resulting analysis allows us to predict which genes would show similar expression signatures in invasive breast cancer and to us to recognize specific biological activities and processes. EGEF algorithm can be used to detect expression signatures in other cancers and biological processes.

Robots are more and more leaving our labs and entering natural interaction settings, such as homes, care facilities, factories, kindergartens, museums, and many more. In the HRI research community, we are aware of all the challenges involved in studying autonomously behaving agents "in the wild". In order "not to go wild" we want to discuss best practices as well as pitfalls in studying robots in natural interaction settings. Specifically, we want to focus on challenges in the development of systems for everyday usage in peoples' homes and on challenges in evaluating these systems in the wild, especially with regard to long-term interaction. We want to discuss and explore common and new methodological approaches to study HRI outside the lab, and collect recommendations for fellow researchers. In tandem, we want to reflect our visions for the "new era of socially capable robots" and how we as robot developers and researchers imagine them to integrate into the fabrics of our everyday life.
