Effects of long-term aerobic activity on plasma levels of apelin and omentin in rats

Background: Apelin and omentin are adipose tissue-secreted hormones and affect the metabolism. Objective: The aim of this study was to investigate the effects of long-term aerobic activity with different intensities on plasma levels of apelin and omentin in female rats. Methods: This experimental study was conducted on 60 Sprague-Dawley female rats (2-month-old) in laboratory affiliated to Shiraz University of Medical Sciences during 2014. Blood samples were taken from15 rats in the pre-test group to measure the variables of interest. The remaining rats were divided into three groups based on treadmill speed (12, 14, and 16 m/min). After a single 45-min session of treadmill running, blood samples were taken. Data were analyzed using two-way ANOVA. Findings: The plasma levels of apelin and omentin were not significantly different between the three post-test groups. But the difference between the pre-test group and the post-test groups was statistically significant. Conclusion: With regards to the results, adipokines response (apelin and omentin) to a singlesession exercise is not the same and the secretion of each one occurs at a specific intensity and duration threshold of sports activity. Keywords: Exercise, Adipokines, Apelin, Omenti

Management of Medication Error Reporting in HIV/AIDS Patients

Background: One of the most frequent medical mistakes that lower patient safety and mortality is medication errors in HIV/AIDS patients. A structured reporting system is necessary for the efficient avoidance of these kinds of mistakes. In order to discover parameters influencing the management of medication mistake reporting in HIV-infected patients, the current research was carried out. Methods: The current research is an example of an applied study that was carried out between 2010 and 2019 utilizing a hybrid (quantitative-qualitative) methodology. First, the primary factors impacting the management of medication mistake reporting in HIV positive patients were collected from a study of the research literature and 35 interviews with experts in the area of treating HIV patients, and a research questionnaire was created utilizing them. Using the Lawshe approach, the questionnaire was sent to and collected from 31 experts in order to assess its content validity. SPSS23 was then used to determine the questionnaire's reliability, which resulted in a Cronbach's alpha value of 0.920. 400 workers who treated HIV/AIDS patients provided information for the data collection. Exploratory factor analysis was used to analyze the data, together with SPSS23 and Lisrel software. Results: Four factors were found to be important in managing medication mistake reporting in HIV patients, including organizational factors (18 variables), person factors (9 variables), educational factors (10 variables), and communication factors (6 variables). The management of medication mistake reporting in HIV patients was impacted most and least by personal and educational variables, with factor loadings of 0.784 and 0.754, respectively. Conclusion: It is preferable to concentrate on individual variables (employee-related hurdles, fear of the repercussions of reporting, and others' reactions) rather than addressing all four aspects at once in order to manage medication mistake reporting in HIV positive patients (managers, colleagues, patients).  Managers, policymakers, specialists from behavioral disease counseling centers, and attending physicians should pay greater attention to both the individual (application and development of the integrated HIV management system)

Loss reduction planning in electric distribution networks of Iran until 2025

In this paper, a loss reduction planning in electric distribution networks is presented based on the successful experiences in distribution utilities of IRAN and some developed countries. The necessary technical and economical parameters of planning are calculated from related projects in IRAN. Cost, time, and benefits of every sub-program including seven loss reduction approaches are determined. Finally, the loss reduction program, the benefit per cost, and the return of investment in optimistic and pessimistic conditions are introduced

Loss reduction experiences in electric power distribution companies of Iran

The experiences of the loss reduction projects in electric power distribution companies (EPDCs) of Iran are presented. The loss reduction methods, which are proposed individually by 14 EPDCs, corresponding energy saving (ES), Investment costs (IC), and loss rate reductions are provided. In order to illustrate the effectiveness and performance of the loss reduction methods, three parameters are proposed as energy saving per investment costs (ESIC), energy saving per quantity (ESPQ), and investment costs per quantity (ICPQ). The overall ESIC of 14 EPDC as well as individual average and standard deviation of the EISC for each method is presented and compared. In addition, the average and standard deviation of the ESPQs and ICPQs for the loss reduction methods, individually, are provided and investigated. These parameters are useful for EPDCs that intend to reduce the electric losses in distribution networks as a benchmark and as a background in the planning purposes
