Abstract: Background: Acute pancreatitis is one of the most serious complications of ERCP. Early diagnosis of post ERCP pancreatitis helps physicians to provide intensive care and possible medical treatment as early as possible. Trypsinogen-2 in urine is a good diagnostic and prognostic marker of acute pancreatitis. Objectives: To evaluate the diagnostic value of urinary trypsinogen-2 dipstick test for early diagnosis of post ERCP pancreatitis. Methods: A total of 37 patients with obstructive jaundice were tested with the urinary trypsinogen-2 dipstick test and serum levels of amylase and lipase before ERCP and 6 hours after ERCP. Results: Post ERCP pancreatitis was diagnosed in 6 (16%) of 37 patients. The sensitivity, specificity, positive predictive value and negative predictive value of urinary trypsinogen-2 dipstick test at 6 hours after ERCP were 100%, 97%, 86%, 100% respectively. At the cutoff level (130 U/L) for lipase, the positive predictive value and negative predictive value all were (100%), however, the positive predictive value and negative predictive value for amylase levels at cutoff (122 U/L) were 60%, 100% respectively. Serum lipase level was the best test for diagnosing post ERCP pancreatitis followed by the urinary trypsinogen-2 dipstick test. Conclusions: The urinary trypsinogen-2 dipstick test can be used as a rapid and easy test for early diagnosis of post ERCP pancreatitis with high sensitivity and specificity.

Abstract: The aim of the present study is to determine the diagnostic usefulness of the measurement of the telomerase activity and DNA electrical properties in peripheral blood from Hepatocellular Carcinoma (HCC) and chronic liver disease. In 10 patients with HCC, 13 with chronic hepatitis C and 7 healthy individuals, we measured peripheral blood telomerase activity by using the telomerase PCR ELISA assay. We examined its sensitivity and specificity in HCC, chronic HCV and its significance in comparison with other tumor markers. Telomerase activity was detected in peripheral blood of 80% hepatocellular carcinoma, 15% of chronic hepatitis C patients and absent in control group. A clear correlation between the incident of increased telomerase activity and that of elevated AFP is evident. The dielectric results indicated that the studied DNA has a dielectric dispersion in the frequency range used. The increase in the electrical conductivity and relaxation time for HCC and chronic disease could be attributed to the increased surface charge density of the DNA macromolecule. It is concluded that detection of telomerase activity in peripheral blood in combination with measurement dielectric dispersion of DNA could increase the accuracy diagnosis of HCC and improve the judgment on its prognosis.

Abstract: The purpose of this study is to determine the relative importance of factors that attract university students to the accounting profession in Lebanon using Theory of Planned Behavior. The significance of this study is based on the previous research which has shown that “intrinsic factors” (attitude toward the behavior) and “parental influence” (subjective norms) are significant predictors of career choice of accounting students. Using a very large judgmental sample from business students focusing on accounting, the researchers in this study constructed a reliable and valid instrument having one item measuring intention to pursue accounting career in Lebanon, four items measuring self efficacy, another four items measuring social influence (subjective norms) and five items measuring attitude and behavioral beliefs. The multiple regression analysis retained “Subjective Norms” in the model and removed “Beliefs and Attitude towards Accountant and CPA”, “Self Efficacy”, and “Perceived Behavioral Control”. The current study showed that path analysis was not an acceptable fit of data. All predictors (paths) except the direct effect between “Subjective Norms” and “intention to pursue accounting career in Lebanon” should be deleted from the model. Findings of this study support that Hypothesis 1—Subjective Norms (perceived social pressure to become or not become CPA) will be a significant positive predictor of intention to Pursue a CPA Career. Furthermore, the current study provided implications for policy making and for further research.

Journal of Geographic Information System (JGIS) , 2015, DOI: 10.4236/jgis.2015.74032
Abstract: Urban growth is a global phenomenon mainly driven by the overpopulation growth particularly in developing countries like Egypt. Pattern and extent of urban growth could be monitored and modelled on a spatial and temporal dimension. GIS and remote sensing data along with other thematic maps were used to analyze the urban growth, pattern and extent in the last century in one of the biggest governorates at the heart of the Nile Delta of Egypt. Both spatial and temporal analyses enabled to identify the pattern of urban growth and subsequently project the nature of future growth. However, the overall urban growth in the last century was 12 times the original built up areas in 1910; the third stage from 1950 to 1972 was the highest stage of urban growth with 124% increase of the built-up area. The dominant pattern of urban growth was linear along highways and railways with majority to the North, North East and North West directions. The study developed a spatial model to project urban growth by 2027, indicating that urban growth in the Menofya Governorate would be continued at the same directions with the same pattern with an estimated increase of 33%. The study provided an understanding of the controlling factors which drove the urban growth along this long time.

Abstract: Background: Bacterial infection in cirrhotic patients is a fatal complication. The high incidence of bacterial infections in those patients may be related to several alterations in the defensive mechanisms against infections and increased intestinal permeability with bacterial translocation. Aim: To evaluate the role of portal hypertension (PH) in predicting the occurrence of bacterial infections in decompensated cirrhosis. Patients and Methods: In this retrospective cohort study, 99 patients—56 males and 43 females, with decompensated liver cirrhosis were included. Diagnosis of liver cirrhosis was based on clinical, laboratory and ultrasonographic examinations. Patients were classified according to the presence of bacterial infection into patients with infection—Group 1, and those without infection—Group 2. Laboratory, abdominal US and upper endoscopic data for all patients were collected. Logistic regression analysis was done to detect the independent factors for prediction of bacterial infection. Results: The mean age of patients was 50.5 ± 14.2 years. Bacterial infection was found in 41 patients (41.4%) and no infection in 58 patients (58.6%). Infected patients showed statistically significant higher values in the level of bilirubin, PT and Child-Pugh score (P value = 0.000) and lower values in the level of albumin, total serum protein and PC than those without infection (P value = 0.006, 0.000 and 0.000 respectively). Portal vein diameter (PVD) and splenic diameter (SD) showed statistically significant higher values in infected patients than in those without infection (P value = 0.028 and 0.000 respectively), also infection was more significantly prevalent in patients with varices than those without varices (P value = 0.000). The independent predictors for bacterial infection were: the age, total serum bilirubin, serum albumin, PT, PC, child score, PVD, SD and the presence of varices. Conclusion: Presence of varices (as a complication of PH) is an independent risk factor for the development of bacterial infection in decompensated cirrhotic patients and reduction of PH by any way could decrease this fatal complication.

Journal of Power and Energy Engineering (JPEE) , 2017, DOI: 10.4236/jpee.2017.55002
Abstract: The present work is based on the comparative study between “Blade-Element- Momentum” (BEM) analysis and “Computational-Fluid-Dynamics” (CFD) analysis of small-scale horizontal axis wind turbine blade. In this study, the pitch is considered as fixed and rotor speed is variable. Firstly, the aerodynamic characteristics of three different specialized airfoils were analyzed to get optimum design parameters of wind turbine blade. Then BEM was performed with the application of the open source wind turbine design and performance computation software Q-Blade v0.6. After that, CFD simulation was done by Ansys CFX software. Here, k-ω “Shear-Stress-Transport” (SST) model was conducted for three-dimensional visualization of turbine performance. However, the best coefficient of performance was observed at 6o angle of attack. At this angle of attack, in the case of BEM, the highest coefficient of performance was 0.47 whereby CFD analysis, it was 0.43. Both studies showed good performance prediction which was a positive step to accelerate the continuous revolution in wind energy sector.

Abstract: The environmental problems described as the devastation of natural balance is one of the most important problems in theworld today. For the solution of this problem, there are two basic axels mentioned. The first axel whose basic reference is theenvironmental protecting is an approach suggesting removing the specific pollution that appears as an environmental problem.The most important approach for this is sustainable development approach.The other axel for the solution of the environmental problems is the radical ecology approach suggesting an altogetherparadigm change from the current production and consumption forms. Deep ecology is accepted in the radical ecology actionsand admits that the man has perceived the nature as a tool and this is the base of environmental problems, and it suggests abiocentric paradigm for the solution.Norwegian Philosopher Arne Naess, the father of Deep ecology, firstly talked about the deep-shallow ecology in “theconference about the future of the third world” in Bükre in 1972. In his article published in 1973 “The Shallow and the Deep,Long-Range Ecology Movements: A Summary”, he brought up the differences between the deep and shallow ecologies anddetermined the principles of deep ecology, and in his article published in 1986 “The Deep Ecological Movement: SomePhilosophical Aspects”, he explained these principles in details. This article in which the differences between the deep and shallowapproaches to the basic environmental problems were expressed is very important for summarizing the basic arguments of deepecologists and bringing up the perspectives developed on the sources of environmental problems.Naess was considering the shallow ecology as protective-environmental action developed for the health and welfare of peoplein developed countries and thinking that there is a struggle against pollution and running out of sources under the shallow ecologyconcept. Also, the shallow ecology has intensified on the first effects of environmental crisis. The shallow ecology considered tohave a human centered opinion has thought the nature as a lifeless thing and has been giving the man the right of ruling thenature. It gives the value of a tool to the nature. So, the shallow ecology has been considered as a type of “intellectual despotism”.Yet, the deep ecology has believed the need of deep changes.As mentioned, the deep ecology refuses the human centered dualism separating nature and man, and considers man andnature as a whole. According to it, nature isn’t the gathering of things independent from each other, but actions net at

Abstract: Despite progressive improvement in treating major depressive disorder (MDD), it remains mostly unresponsive to one antidepressant medication. Zinc is a brain highly abundant trace metal, a brain derived neurotrophic factor (BDNF) inducer, a modulator of synaptic plasticity and potent suppressor of the NMDA receptors. We proposed that co-administration of zinc with the antide-pressants may represent a valuable regimen to improve the efficacy of these drugs. This work has been implemented to evaluate the behavioral changes of acute and sub-acute co-administration of zinc with Paroxtine in mice. Methods: The animals were injected intra-peritoneal with either Paroxtine (20 mg/kg) which was a selective serotonin reuptake inhibitor (SSRI), zinc sulfate (30 mg/kg) or Paroxtine in combination with zinc for one day and one week (once daily). The pattern of the animal behavior was assessed in the forced swim test (FST). Results and Discussion: The behavioral patterns of the animals in the FST include immobility, swimming and climbing. Successful antidepressant should decrease the immobility time with either increase in swimming and/or climbing behavior based on the drug pharmacological activity. Our results revealed a significant decrease of immobility and increase of swimming behavior indicating serotonin-dependent pharmacological activity of Paroxtine or zinc alone as well as in the animals treated with zinc in combination with Paroxtine. There was no significant difference in the animals’ behavior between acute and sub-acute treatment with zinc or even upon its addition to paroxetine. Our data support the concept that co-administration of zinc may provide further antidepressant activity. Zinc may offer additional clinical value particularly in geriatric patients or other populations where zinc level has shown dramatic decrease.

Abstract: Background and aims: CD64 [Fc gamma receptor 1 (FcγRI)] is a promising biomarker used in predicting severe bacterial infection. The study was designed to assess their level in all stages of HBV infection and in chronic HCV infection before and after treatment with direct acting antiviral therapy as a possible biomarker of inflammation. Patients and methods: A case-control study was conducted, 50 patients with different disease stages of HBV infection (10 acute, 15 chronic hepatitis, 15 liver cirrhosis (LC) and 10 with hepatocellular carcinoma (HCC)), twenty patients with chronic HCV and 15 as a control group. Laboratory and imaging studies were evaluated. The levels of CD64 expressions in peripheral blood and CD64 Index were measured for all patients by flowcytometry using fluorescein isothiocyanate (FITC)-conjugated anti-CD64 monoclonal antibody. Results: The levels of CD64 expressions in peripheral blood and CD64 index were significantly higher in patients with HBV and HCV than in control group (P value = 0.01, 0.01 and 0.000, 0.000 respectively). They were increased significantly with disease progression in patients with HBV infection, acute hepatitis B infection showed the highest values. Their levels were significantly decreased in patients with HCV infection post treatment than before treatment. Conclusions: The levels of CD64 expressions in peripheral blood and CD64 index are considered good biomarkers of inflammation in viral hepatitis both B and C and could detect disease progression and also suppression of inflammation after antiviral therapy.
