Abstract: Previous studies have provided evidences that, higher accrual profitability obligation in comparison with accrual profitability in each period is associated with lower profitability performance in future periods. These findings were interpreted as an increase in operating accruals adversely affect operating profit in future periods, thus decreasing the profitability of coming period. In this study, we demonstrated that, accrual profitability has no adverse effect on the operating profitability of the next period and lower stability of current accrual profitability to cash profitability in relation with operating profit of the next period lies beneath the stronger correlation between current accrual profitability and cash profitability with net operating assets.

Abstract: Aim of this paper is to study relationship between social alienation and identity status of university students. Methodology of this study is survey. In order to measure social alienation, we use Melvin Seeman’s scale including feelings of powerlessness, social anomie, social isolation, meaninglessness, and Estrangement. We also use identity status EIS2-EOM Test provided by Adams and Benion (1989) to measure identity status. Statistical population of this study includes students of Islamic Azad University. The sample includes 380 students chosen through proportional stratified sampling method based on student’s gender and faculty. Findings of this study show that there is significant correlation between social alienation and identity status of subjects. Average of alienation among males is 48.5 and females’ average is 49.3. This relation is statistically meaningful.  Test  shows that there is significant correlation between identity status and faculty. Rate of this relation in Phi test is 0.38. People with successful identity status who have passed the crisis and got some commitments, they rarely confront with social alienation, they use influential social skills and behave appropriately in anomic situation.

Abstract: Studied area is located in northen Tabriz (Northwest of Iran). Thickness of Triassic sedimentary rocks in this region is 855 meters. The base of these rocks is isocline with Permian units and the top have angular unconformity with Miocene sediments. These sedimentary rocks can be divided into carbonate and terrigenous facies. Based on the microscopic and field studies five facies can be recognize in carbonates. These facies relates to supratidal, intertidal, lagoon, barrier and open marine environmens. Terrigenous part includes massive polymictic carbonate conglomerate. This conglomerate generated in type-scott of braided Rivers.  Based on facies cycle, three sequences are distinguished in this sedimentary record. The lower boundary of the first sequence is SB2 and upper boundary of the third sequence is SB1.

Abstract: Emotion and excitation affections are considered in special times as the cause in commission of a crime among people. In some of these cases, these excitation and emotion undergo profound alternations, so that they become similar to some of the other states. Incitement as one of the mitigating defenses of punishment has a partly long history in common law system. Against, this category hasn’t been considered more in Germanic-roman law system and Islamic religious jurisprudence. Thus, in our law system that composed of Germanic-roman and Islamic law system, you can’t find rules and general doctrines commanding on this excuse in form of comprehensive and formularized. Just some of incitement forms are presumable and extractible as mitigating reasons or improving punishment between formularized laws. Nevertheless, this topic has been placed clearly in different materials in Azerbaijan punishment law. In this paper, first, doctrines and rules commanding on common penalty law and as regards to Iran and Azerbaijan law system will be analyzed and investigated.

Abstract: The purpose of this study was to evaluate the impact of corrective exercises on Max oxygen intake and heart rate indexes in girls (12-15 years old) with scoliosis. 40 girls (12-15 years old) with scoliosis were selected randomly from a guidance school and divided to two groups, 20 in experimental and 20 in control ones. All participants filled out the form to ensure that they had no heart and cardiovascular disease, in order to perform the required tests. After measuring the height and weight of participants, they were familiar with the tests. The pre-test consisted of the scoliosis evaluation, static strength and flexibility of back muscles and range of bending motion. Both groups practiced training programs for four weeks, each week four sessions for an hour and a half. Data were analyzed by paired t and independent t test and chi-square test (chi square). The research results demonstrated that the spinal flexibility and back muscles strength increased in the experimental group after a period of corrective movements, but there was not a significant difference between experimental and control groups. Corrective exercises had a positive impact on the level of the posterior superior iliac spine and there was significant difference between experimental and control groups. Corrective exercises had a positive impact on the shoulders surface, but there was not a significant difference between experimental and control groups. Lateral bending in the subjects of our research was asymmetrical and the results of corrective exercises did not show any significant difference in both groups.

Abstract: The purpose of the present research was to study the effect of motivational self-talk on performance in a force generation task with an emphasis on self-talk belief. 23 participants (23.5 1.9 years old) voluntarily participated in the research. The performance of the participants was measured by a dynamometer under a control and an experimental condition. In the experimental condition (self-talk), the participants uttered “I can do it” before exerting force on the device, while in the control condition no sentence was uttered before the task. Immediately after the test the participants filled out a self-talk belief questionnaire as well as a manipulation check survey. The results showed that self-talk leads to improved performance in the force generation task, but there was no significant relationship between self-talk belief and performance. In general, it seems that self-talk belief is not an important antecedent for the effect of self-talk on performance.

Abstract: The main aim of the study was to evaluate the effective factors on forming and implementing volunteer movement in Hormozghan province. The present research methodology was descriptive-analysis and its statistical community is subjected to the bosses and vice-presidents of the province sport boards with 88 people in this study which questionnaires were divided and then collected among them efficiently. The research tool is an authentic questionnaire using comprehensive references which its reliability and authenticity was based on common methods evaluated as well. To analysis data, the descriptive statistics and inferential statistical (U-Mann Whitney and Friedman test) using Spss 19 were applied in this regard. The results showed that ranking factors subjected to the attraction of people, preserving and maintaining people, educating and developing volunteer movement had priorities from the first to fourth, respectively in the province. Also, it is determined that we can try more tendency towards absorbing volunteers than recruitment, making great relationship between sport officials and volunteers, providing suitable planning to evaluate volunteers activity and participation management to be applicable in implementing effective approaches in the field of volunteer movement. Usually, there must be a strategic approach to make its connection between sport officials in the province (Hormozgan), particularly absorbing factor which it can expand the sport affairs due to the existence of more young forces interested in sport issues assisting to the sport of the province in near future.

Abstract: Background: Basal cell carcinoma is the most common malignant tumor in humans. Some immunohistochemical markers such as P53 gene mutation have been known in the pathogenesis. This study was done to investigate the frequency of immunohistochemical expression and intensity of P53 as a tumor marker and its correlation with other data such as age, sex and anatomical site of the tumor in all histopathological types. Methods: This cross sectional study was done on one hundred basal cell carcinoma specimens. At first the specimens were fixed by formalin, and stained by hematoxylin-eosin. Histopathological types of the tumor were determined. Immunohistochemical expression and intensity of P53 was investigated. Other data such as age, sex and anatomical site of the tumor were collected. Results: The specimens comprised 62 men (62%) and 38 women (38%), ages 22-107 years. Prevalence of P53 expression was 76%. The intensity of the P53 was strong in 70% and weak in 30% of cases. There was not a significant correlation between this marker and other variables (P> 0.05). Conclusions: In total we indicated that P53 mutation may possibly play a role in basal cell carcinoma. Our study does not support a correlation between expression of this marker with gender and anatomical lesion sites. In addition, there was not a significance association between the histopathological types based on the P53 expression and staining intensity of it.

Abstract: The suitability of a specific location for proposed facility operations depends largely on what location factors are selected and evaluated as well as their potential impact on corporate objectives and operations. Facility location problem is a typical Multi Criteria Decision Making (MCDM) problem which involves many conflicting attributes. In this paper we try to tackle this well known problem by combining the Standard Deviation to allocate the weights, then combining the proposed method to Multi-Objective Optimization on the basis of Ratio Analysis (MOORA) technique. An international company's  facility location problem of a new manner is illustrated. The new approach so-called SDV-MOORA is employed to solve the MCDM problem.

Abstract: Various objectives are usually taken into account when projects are analyzed, including economic desirability, technical issues, and environmental and social factors. As the decision maker tries to maximize or minimize outcomes associated with each objective depending on its nature, so a Multi-Criteria Decision Making (MCDM) problem arises. In this article, a new method is developed to assign weights to criteria when there is no preference among them based on the Standard Deviation (SDV) and Multi-Objective Optimization on the basis of Ratio Analysis (MOORA) technique. A MCDM project selection problem found in real-life international company is presented.The new approach so-called SDV-MOORA is employed to solve the MCDM problem.

Abstract: A community based, cross-sectional survey was undertaken on the anthropometric status of Kurmanj, non-pregnant women of childbearing age in the North-eastern of Iran. The main purpose of this investigation was to determine normative anthropometric standards in women of childbearing age. Interviews and anthropometric measurements were completed on 473 non-pregnant women randomly selected and stratified by five year age categories from eight peasant associations. The mean (SD) weight was found to be 46.9(5.3) kg, with 75% weighing less than 50 kg. Women’s height averaged 155.5 cm with nearly 20% under 150 cm. The mean (SD) BMI was 19.4 (1.9) kg/m2 and 35% of the women had a BMI lower than 18.5 kg/m2. Means for all anthropometric measurements fell below the 10th percentile of the standard NCHS reference for women. All anthropometric outcomes were stable across age categories. The relation between these anthropometric measures and adverse health outcomes will require validation.

Abstract: Electronic learning is the future  learning that delivers comprehensive contents to students in comfortable time and conditions chosen by learners needs. Faculty members and expert engineers helping them in using  recent technologies and to stay informed about the latest developments, and transfer what they have learned to new generations of students. Aim of this study was: To establish electronic gate to Alexandria Faculty of Medicine as an alternative or complementary method for teaching both postgraduates and undergraduate medical students. To enhance faculty members and student levels of skills toward integrating e-learning in their teaching.  Design: 3 years Cross sectional descriptive and applied analytical study was used in this study. Subjects: 150 Staff faculty members, 150 postgraduate students as well as 1200 undergraduate medical students were involved in the study. Tools: First year (2010) was stressed on training staff members on online courses by weekly lectures and regular workshops. Second year (2011) was dedicated in creating and applying 21 postgraduate academic and clinical medical on line courses. Third year(2012) was concentrated on online regular exams for 4th, 5th, and 6th medical students together with reapplying postgraduate e-courses after their modification by following the feedback from previous courses.   A structured questionnaire was developed by the researchers in four parts: Part one included information of participants experience in teaching using recent technologies. Part two included participant’s attitudes on the  usefulness of recent  technology. Part three included participant’s (students and professors) supporting electronic learning. Part four feedback (survey) questioner’ prepared by technical support and submitted by postgraduate students after each e-course. Lastly an e-course comprehensive  contents with  was prepared by team of staff members (Professors, Assistants, Lecturers and Demonstrators) in the form of power points, video films, animations, weekly activity(either quiz or assignment) for totally 40 marks i.e. continuous assessment , midterm quiz at 7th week for 20 marks and a final on line exam.at the 15th week for the rest 40%.The on line exams were in the form of multiple choices, true or false and matching. All the resources (contents), quizzes and e-exams were prepared and uploaded by Medical Staff Members with assistance of Technical Support Engineers(Electronic unit team). Our results revealed a high rate of willingness of students(80%) and staff (60%)to use electronic teaching and exams. in terms of convenience, simplicity and saving money of transport and working at the same time of studying (postgraduates more than undergraduates who still need face to face teaching).

Controls losses in Depleted Reservoirs and high-permeability formations using Nanomaterial as a new mud product.

Abstract: Losses of whole mud to subsurface formations is called lost circulation or lost returns.  Lost circulation has historically been one of the primary contributors to high mud costs. Other hole problems such as wellbore instability, stuck pipe and even blowouts have been the result of lost circulation. Besides the obvious benefits of maintaining circulation, preventing or curing mud losses is important to other drilling objectives such as obtaining good quality formation evaluation and achieving an effective primary cement bond on casing. The severity of losses ranges from minor seepage to complete losses with no returns regardless of the technique utilized to cure the problem. Under-balanced drilling with aerated fluids, foams or density-reducing beads has been successful in many areas. Injection of compressed air or nitrogen is usually necessary to accomplish the density reduction needed to achieve under-balanced conditions. Besides minimizing or preventing lost circulation, these techniques are also used to provide enhanced penetration rates and reduce formation damage due to invasion of drilling fluids or filtrate. In this study, novel fluids as Aphron drilling Nano-fluid have three chief attributes that serve to minimize fluid invasion and damage of producing formations. First, the base fluid is very shear thinning and not very thixotropic, exhibiting an extraordinarily high low-shear-rate viscosity (LSRV) and flat gels; the unique viscosity profile is thought to reduce the flow rate of the fluid dramatically upon entering a loss zone. Second, various components in the mud interact to produce micro-gels that help to reduce spurt loss. Finally, very tough and flexible micro-bubbles, called “Aphrons,” create a soft seal within the permeable or fractured formation to reduce losses further. Aphron drilling fluids, which are highly shear-thinning water-based fluids containing stabilized air-filled bubbles (Aphrons), have been applied successfully worldwide to drill depleted reservoirs and other high-permeability formations as well as fracture Granite formations. Based on laboratory determinations, the smallest size for a gas-core Aphron is 25 m. The bubbles smaller than this size are not able to maintain the surfactant-based boundary separating them from the bulk water and thus get dispersed in the continuous water phase. From field study, Aphron ICS mud was used to drill KHA 403 and 404 wells (Yamen) compared to previous wells drilled with a polymer mud. The total volume of Aphron drilling fluid built to drill the reservoir interval was 696m3, and losses incurred totaled 265 m3 into formation fractures. A subsequent well, KHA 404, was drilled in the same area with the APHRON ICS mud, and it experienced no losses of the APHRON ICS mud and even greater production. Hydraulics relative to offset wells drilled with simple water-based polymer muds, it is reported that hole cleaning was substantially improved, even during periods when pump rate had to   be reduced in an effort to mitigate downhole losses, indicating minimal invasion of drilled solids into the fractures drilled.

Abstract: The study designed to evaluate the protective effect of Salvia officinalis (SO) water extract against OVA- induced asthma in mice. The OVA-induced asthmatic mice exhibited significant increase in total leukocytes count, IL-4 and IL-5 levels in bronchoalveolar lavage fluid (BALF) and eosinophils count in (BALF), in addition, to the serum total IgE level. Pathological changes in the lung were evaluated and compared to either treated OVA-challenged SO group or control- Salvia Officinalis oral administered group. Salvia Officinalis extract reduced significantly the number of inflammatory cells and cytokines in the BALF and the level of IgE as compared to OVA-challenged group. Moreover, Salvia Officinalis extract (SO) reduced the eosinophils infiltration in the lung tissue.  These results suggest that Salvia officinalis extract via oral treatment may have anti-inflammatory and immune regulatory effects on bronchial allergic asthma.

Abstract: Bachground: Visfatin is a one of the recently discovered adipokine that has an important pro-inflammatory and catabolic roles in rheumatoid arthritis (RA). Pro-inflammatory cytokines, such as interleukin (IL)-1, IL-6, IL-15, IL-18 and tumor necrosis factor-α (TNF-α), initiate a number of physiological changes that result in the characteristic signs of inflammation. Since inflammation is the major factor leading to structural damage, it is critical to achieve rapid suppression of inflammation to maximize disease control. Objective: to evaluate the role of serum visfatin as a recent pro-inflammatory marker in RA according to the activity scores of disease to assess the possibility of introducing serum visfatin in the diagnosis and monitoring of RA patients and correlate between its serum level and other cytokines (IL-6 and TNF-a) and other laboratory biomarkers. Patients and methods: This study was conducted on a total number of 80 individuals, 60 of them were RA (48 females 80% , 12 males 20%) diagnosed as RA according to the American College of Rheumatology (ACR) / The European League Against Rheumatism (EULAR) 2010 criteria  and 20 healthy subjects as a control (10 females 50%, 10 males 50%). RA patients were classified to 3 groups:Group I (severe RA): 20 RA patients, Group II  (moderate RA): 20 RA patients and Group III (mild RA): 20 RA patients according to clinical evaluation for disease activity assessed using a 28 joint disease activity score, (DAS-28). Blood samples were obtained from patients and controls for CBC and ESR. The sera of patients collected for ELISA estimation of serum visfatin , IL6 and TNF-a. CRP and RF were determined by turbidimetry quantitative method. Results: The comparison between the RA and control groups showed that; the mean serum level of visfatin, Platelets (PLT), ESR, IL6, CRP and RF were significantly higher in RA patients than control group .  The comparison between the mild, moderate and severe RA groups showed that the mean  levels of visfatin and IL-6 were significantly higher in severe RA group than moderate RA group which was significantly higher than mild RA group.   There was a significant positive correlation between  serum visfatin and {IL-6, ESR, CRP,  TNFα and DAS 28} in RA group. Conclusion:  Visfatin has a role in the pathogenesis of RA and could be considered as a disease marker in RA and a marker of radiographic bone damage and hence as a potential therapeutic target for RA. The finding of present study indicate also that serum visfatin and IL-6 might be of a valuable diagnostic value for RA, however the combined diagnosis using serum visfatin , IL-6 and RF test can improve RA diagnosis in early stage. Further studies are needed to determine the possibility of introducing visfatin as a potential therapeutic target especially in early RA to prevent erosions.

Abstract: Bachground: Visfatin is a one of the recently discovered adipokine that has an important pro-inflammatory and catabolic roles in rheumatoid arthritis (RA). Pro-inflammatory cytokines, such as interleukin (IL)-1, IL-6, IL-15, IL-18 and tumor necrosis factor-α (TNF-α), initiate a number of physiological changes that result in the characteristic signs of inflammation. Since inflammation is the major factor leading to structural damage, it is critical to achieve rapid suppression of inflammation to maximize disease control. Objective: to evaluate the role of serum visfatin as a recent pro-inflammatory marker in RA according to the activity scores of disease to assess the possibility of introducing serum visfatin in the diagnosis and monitoring of RA patients and correlate between its serum level and other cytokines (IL-6 and TNF-a) and other laboratory biomarkers.

Abstract:  Background: The severity of joint pain and joint stiffness and their effects on walking variables especially in children who have juvenile rheumatoid arthritis (JRA) are serious and represent functional problems. So, the aim of this study was to investigate the effect of pulsed magnetic field (PMF) on lean muscle mass and fat mass in children with juvenile rheumatoid arthritis. Methods: Thirty children with polyarticular JRA were included in this study. Fifteen children represent control group who treated with therapeutic exercises only and fifteen children represent study group who treated with pulsed magnetic field and therapeutic exercises. Lean muscle mass and fat mass were determined before and after six months of treatment. Results: The current Study showed significant changes in both lean muscle mass and fat mass in study group compared with control group. Pre-treatment results of mean lean muscle mass was 23975.2 8152.21 g. in control group and 24016.26 7864.39 g. in study group. There was no significant difference between both groups which indicate that they were homogenous (p = 0.98). But post-treatment results showed that mean lean muscle mass was 27143.26 8223.52 g. in control group while that of study group was 35755.46 7106.45 g. which was significantly higher than the control group (p = 0.05). Also, pre-treatment results of mean fat mass were 10742.13 5466 g. in control group and 12358.53 6210.27 g. in study group. There was no significant difference between both groups which indicate that they were homogenous (p = 0.45). But post-treatment results showed that mean fat mass was 10008.26 5110.66 g. in control group while that of study group was 6265 3957.92 g. which was statistically significant than the control group (p = 0.03). Conclusion: Pulsed magnetic field together with therapeutic exercises are effective in increasing lean muscle mass and decreasing fat mass in children with polyarticular JRA than therapeutic exercises alone.

Abstract: Purpose: The purpose of this study was to compare the efficacy and safety of two different chemotherapy regimens in the treatment of advanced pancreatic cancer (PC). Material and Methods: Thirty-nine patients with advanced (local advanced and/or metastatic) unresectable pancreatic adenocarcinoma were enrolled in this study and assigned to receive gemcitabine 1000 mg/m2 intravenous infusion (IVI) on days 1 and 8 plus oral (po) capecitabine 825 mg/m2 twice daily, days 1–14 followed by a treatment free interval of seven days (Gem-Cap) or gemcitabine 1000 mg/m2 IVI on days 1 and 8 plus oxaliplatin 130 mg/m2 IVI on day 8 (Gem-Ox). Treatment cycles were repeated every three weeks. The primary study end point was assessment of the overall survival (OS) rate; secondary end points were, assessment of the progression-free survival (PFS) rate, objective response rate (ORR), and treatment toxicity. Results: The median follow up time for all patients was 18 weeks. At the time of final analysis, 35 (89.7%) deaths had occurred. Out of the total 39 patients, there were no complete response (CR), 23.8% in the Gem-Cap arm and 22.2% in the Gem-Ox arm had partial response (PR) while 33.3% and 44.4% had stable disease (SD) respectively. Progressive disease occurred in 42.9% of Gem-Cap arm and in 33.3% of the Gem-Ox arm. Patients assigned to Gem-Ox had apparent but not significant improved overall response rate over Gem-Cap (p=0.759). The 1-year OS rate was 9.52% in the Gem-Cap arm vs. 11.11% in the Gem-Ox arm, (p=0.792). The corresponding median survival time was 18 weeks vs. 17 weeks, respectively (p=0.717). The 1-year PFS rate was 4.76% in the Gem-Cap arm and 8.33% in the Gem-Ox arm, (p=0.715). Median PFS was estimated with 15 weeks and 14 weeks, respectively (p=0.388). Grade 3/4 hematological toxicities were more frequent in the Gem-Cap arm than Gem-Ox arm (28.6% vs. 5.6% respectively, p<0.05). Non-hematological toxicity presented with peripheral neuropathy was more frequent in Gem-Ox arm, p=<0.001, whereas hand-foot syndrome was more in Gem-Cap arm, p=0.001. Conclusion: Although our study had the limitation of being a single center study with a small sample of enrolled patients, our results can conclude that, the advanced pancreatic cancer is a fatal disease. The efficacy of the Gem-Ox regimen in the treatment of advanced PC seems to be similar to Gem-Cap regimen. However, the toxicity profile of the Gem-Ox regimen is different with significantly fewer hematological adverse events and the major side-effects were peripheral neuropathy whereas, the hand-foot syndrome being the main non-hematological toxicity in the Gem-Cap arm. Further multi-centers trials with large number of patient comparing different multi-agents' regimens with different dosage schedules for patients with advanced PC are warranted.

Abstract: Lupus nephritis is known as one of the most serious manifestations of systemic lupus erythematosus (SLE). There is increasing interest in identifying biomarkers to predict flare of lupus nephritis (LN). It is hoped that non-invasive markers of renal disease can be used to predict flares and remission of disease. Recently, two promising biological markers, anti C1q autoantibody, and serum prolactin were addressed as diagnostic and prognostic markers for lupus nephritis. Aim of this study wasto determine the diagnostic and prognostic values of anti-C1q antibodies, and prolactin as simple and easy biological markers for lupus nephritis-two years follow up.Patients and Methods; 60 active SLE patients divided into two groups, group 1;30 patients with active nephritis, and group 2; 30active SLE patientswithout nephritis. All the patients subjected to complete history andphysical examination. The demographic, clinical and laboratory variables and the disease activity index (SLEDAI) were analyzed. Patients with lupus nephritis WHO class III, IV or V received glucocorticoid and cyclophosphamide for induction of remission.  For all the patients, anti C1q, prolactin, anti ds DNA, C3, C4 were measured. Kidney assessment included, urinary sediments, and protein/creatinin ratio, biopsy only for group 1. The length of the follow up was 2 years. Results; the age of the patients, and the duration of the disease were significant higher in-group 1than in group2 (P< 0.001 for both). No significant difference in two groups considering the sex. Prevalence and level of ant C1q, and prolactin were higher in-group 1 than in-group 2 (P<0.001).  Both of them were correlated with the renal score activity at the time of sampling, and at the end of the study. Anti ds DNA did not correlated with the renal activity score. Anti C1q had high sensitivity, and accuracy (86.7%, 0.9) than prolactin (50%, 0.7), versus high specificity of prolactin (100 %). Conclusion: anti-C1q antibodies, and prolactin might be valuable serological biomarkers to reflect kidney involvement and to monitor disease activity of LN.

Abstract: There is a growing awareness of the need for changes in nursing education systems, especially in developing self-learning techniques where the student is an active participant in the learning process. Nursing students are exposed to a vast amount of information and reading material that is very specific, technical, and new to the students, they need to able to link learned facts, concepts and principles with new knowledge in order to make sound rational decisions in practice. Concept mapping, a learning strategy used to understand key concepts and relationships between concepts, has been suggested as a method to plan and evaluate nursing care. The purposes for this study were to (1) Find out whether concept mapping improved students’ learning achievement in an advanced nursing courses within the nursing baccalaureate program; and Identify students’ attitudes towards using concept mapping as a learning tool. Method(s): One-group pretest-posttest quasi-experimental design used with senior-level baccalaureate students (n = 46) students from two classes enrolled in an advanced nursing  course at taif - university in saudi Araba. Students completed questionnaires to self-evaluate their learning and report their satisfaction with concept mapping. Tools were constructed to collect the data, demographic questionnaire, End-of-Training-Concept of Mapping Usage Questionnaire, and End of Semester Concept Map Usage Questionnaire. Results: The experimental data revealed two important results. First, adopting a concept mapping strategy can significantly improve students’ learning achievement compared to using a traditional teaching method. Second, most of the students were satisfied with using concept mapping in advanced nursing courses. Conclusions & Recommendations: This study supported concept mapping as an additional learning strategy and has extended knowledge in the nursing education and also enhance student  interests in learning nursing. Student also thought that concept mapping could be usefully used in other curriculum areas. Further study is recommended to study the relationship between learning style preference and concept mapping as a teaching strategy.

Abstract: Central venous catheter-related blood stream infection (CRBSI) is associated with high rates of morbidity and mortality in critically ill patients. This study was conducted to determine the incidence of central venous catheter-related infections (CRIs) according to different access sites, isolation, identification and determination of the predominant microorganisms involved and to determine the risk factors for infection by statistical analysis of the results to contribute the elaboration of actions to prevent and control blood stream infections and mortality among those patients. A total of 160 adult patients with indwelling central venous catheters hospitalized at intensive care units (ICUs) were enrolled in this study. A total of 640 clinical samples were collected from the patients; 4 different samples collected from each patient: 320 blood samples; 160 (pre-catheterized) and the other 160 (post-catheterization), 160 catheter tips and 160 swabs. The clinical samples were cultured on ordinary media for isolation and identification of the isolated microorganisms. Antibiotic sensitivity was determined by disk diffusion method according to National Committee of Clinical Laboratory Standard 2007 (NCCLS). Microscan automated system was also used for both identification and antimicrobial sensitivity testing. Statistical analysis used SPSS-10 version statistical software. One hundred forty two out of 160 patients (88.75%) suffered from CRIs. Catheter related infections were categorized according to CDC guidelines into Catheter-Related Blood Stream Infection (CR-BSI), Clinical Blood Stream Infection (C-BSI), Bloodstream Infection (BSI), Catheter bacteremia (CB) and Exit Site Infection (ESI), their rates were 23.2%, 8.5%, 47.9%, 2.8 % and 0.7% respectively and 16.9% were mixed infections. Semiquantitative culture was used for CRIs diagnosis. The total number of pathogens was 293 microorganisms were isolated from 261 positive cultures. Out of them 139 (47.4%) were Gram positive bacteria, 136 (46.4%) were Gram negative bacteria and 18 (6.1%) were Fungi. High frequency of microorganisms were isolated from post catheterization blood specimens (80.63%) followed by catheter tip samples (44.3%), swabs (29.4%) and the pre-catheterization blood specimens showed the lowest frequency of isolated microorganisms (6.88%).The isolated microorganisms identified by conventional and semiquantitative methods were belonging to 17 different species. The main etiological Gram positive bacteria was Coagulase negative Staphylococci (CoNS) representing (30.8%) and the main etiological Gram negative bacteria was Klebsiella pneumonia representing (10.6%). Pathogens isolated from CR-BSI were 42 isolates belonging to 13 different species; the most prevalent isolate was CoNS representing (42.9%). Pathogens isolated from C-BSI were 12 isolates belonging to 6 different species, the most prevalent isolate was S. aureus representing (41.7%) while 83 pathogens were isolated from BSI and they were belonging to 14 different species, the most prevalent isolates were CoNS representing (38.6%). Pseudomonas aeruginosa was the microorganism isolated from the single ESI detected in the study. The isolated pathogens from CRIs showed a wide range of antibiotic resistance. The emergence of multi-resistant pathogens in ICUs was highly detected in the present study. The most Gram positive and Gram negative bacteria causing CRIs were sensitive to imipenem and vancomycin. Proper insertion and care of catheters are essential to avoid infection. Education and training of health professionals on the practice of dealing with the CVC is an important tool in preventing and reducing CRIs.

Abstract: Background: The anti-inflammatory and reparative properties of mesenchymal stem cells (MSCs) make them a promising tool for treating inflammatory and immune-mediated disorders. T cell dysfunction is undoubtedly a key feature in the pathogenesis of inflammatory bowel disease (IBD). MSCs suppress proliferation and alloreactivity of T cells, where several signaling molecules contribute to this effect. Galectins, a family of β-galactoside binding proteins, now emerge as a main regulator of MSCs immunomodulatory function. However, whether MSCs can be used for treatment of IBD still remains unclear. Aim: In this study, a dextran sulfate sodium (DSS) - induced colitis model was used to test the effect of infused bone marrow-derived MSCs on immunomodulatory molecules and if they could exert anti-inflammatory effects against experimental colitis.Methods: The study was carried on female albino rats, which were divided into three groups; Group 1 [Control group], Group 2 [Dextran sulfate sodium (DSS)-induced colitis group] and Group 3 [MSCs treated group]. Serum values of pro-inflammatory cytokines [tumor necrosis factor-alpha (TNF-α) and interleukin 6 (IL6)] as well as anti-inflammatory cytokines [interleukin 10 (IL10) and prostaglandin E2 (PGE2)] in the three groups were evaluated quantitatively by enzyme-linked immunosorbent assay (ELISA). Quantitative analysis of galectins 1, 2, 3 and 4 as well as basic fibroblast growth factor (bFGF) gene expression was done by Real Time PCR. Colon sections were stained with hematoxylin and eosin and examined for histopathological changes. Results: DSS-induced colitis group showed similar findings to that of ulcerative colitis in human, including body weight loss, bloody diarrhea, mucosal inflammation and ulceration. PKH26 labeled bone marrow-derived MSCs accumulated in inflamed regions of the colon, mainly in the submucosa and significantly ameliorated the clinical and histopathologic severity of DSS-induced colitis. Pro-inflammatory cytokines (TNF-α and IL6) were significantly lower in MSCs-treated rats compared to DSS-induced colitis rats. On the contrary, anti-inflammatory cytokines IL10, PGE2 and bFGF were significantly higher in MSCs-treated rats compared to DSS-induced colitis rats. Galectin 1 (Gal1), Galectin 2 (Gal2), Galectin 3 (Gal3) and Galectin 4 (Gal4) were significantly higher in MSCs-treated rats compared to DSS-induced colitis rats. Conclusions: Systemic infusion of bone marrow-derived MSCs may exert therapeutic efficacy on acute DSS-induced colitis in rats through their immonumodulatory and anti-inflammatory effects, which demonstrates the feasibility of using bone marrow-derived MSCs to treat IBD. Also the results presented in this study illustrate the involvement of the measured members of the endogenous galectin family (galectins 1, 2, 3 and 4) in the experimental model of colitis. The changes in their levels during inflammation evidenced that they play important role in MSCs immunomodulatory and anti-inflammatory actions.

Abstract: Background: Pseudomonas spp. is one of the most frequent nosocomial pathogen that is often difficult to treat due to a multi-drug resistant pattern to a wide range of antibiotics like carbapenems.  Imipenem-resistant Pseudomonas aeruginosa (IRP) resulting from metallo-b-lactamases has been reported to be an important cause of nosocomial infection and is a critical therapeutic problem worldwide, especially in the case of bacteremia. Objectives: In this work we aimed to detect Carbapenemase and MBL production as well as   molecular detection of bla IMP gene in impenem resistant nosocomial isolates of Pseudomonas spp. Material and Methods:A total number of 150 Pseudomonas isolates were collected from clinical specimens submitted to Ain Shams University microbiology Laboratory for culture and antibiotic susceptibility testing.We used the Imipenem E-test strips to determine the MIC of the IPM resistant isolates .Screening for Carbapenemase and Metallo-β-lactamase was done phenotypically using modified hodge test (MHT) and Imipenem-EDTA Double disk Synergy test (DDST), also molecular detection of blaIMP gene was performed. Results: It was found that 38 out of 150 isolates (25.4%) were resistant to impenem by disc diffusion method which confirmed by E test that showed only 27 out of 150 (18%) were resistant.  Ten Out of 27 isolates (37%) were expressed blaIMP gene. However, The Modified Hodge Test Positive isolates were 13 out of 27 E-test resistant isolates (48.1%). While the DDST   positive isolates were 21 out of 27 (77.8%) of   E-test resistant isolates. Conclusion: Metallo-b-lactamases among imipenem-resistant Pseudomonas   were detected in 37% by PCR. This number might have been higher if other genes were included. Phenotypic tests   could be misleading when testing for metallo-b-lactamases. Polymerase Chain Reaction detection remains the gold standard.

Abstract: Background: Non-pharmacological methods have unique advantages to relieving pain that medications do not have such as giving the patients a more active role in managing their pain. There are many types of non-pharmacological methods that vary amongst heat/cold, distraction, massage and relaxation. Nurses must have a great knowledge of non-pharmacological methods to practice them effectively. In addition, nurses' own attitudes greatly affect the way they treat a patient's pain. This study aimed to evaluate nurses' knowledge, attitudes and practices regarding non-pharmacological pain management in selected hospitals at Makkah El-Mukarmah. Subjects and methods: 120 nurses, males and females working in medical and surgical wards in selected three hospitals at Makkah El-Mukarramah. The data was collected through using a self-administered questionnaire consisting of three parts; a socio-demographic characteristics questionnaire, a nurse's knowledge assessment questionnaire, and a non-pharmacological methods questionnaire. The results show: knowledge and practices were at a satisfactory level. However, the percentage of applied non-pharmacological pain management was low in hospitals because of a lack of time. There was a positive relationship between age, educational level, years of experience, and attendance on training courses with the knowledge and practice and positive relationship between knowledge and practice of the nursing staff regarding non-pharmacological methods. Conclusion: Nurses have a satisfactory level of knowledge and that leads them to have a positive attitude and a high level of efficiency in applying non-pharmacological methods for pain management. Recommendation: This study recommended that efforts to improve application of nondrug interventions should focus on innovative educational strategies, using problem solving to secure support, and development and testing of new delivery methods that require less time from busy staff nurses.

Abstract: Quantitative determination of the total polyphenols and flavonoids of aerial parts of Cotoneaster horizontalis Decne family Rosaceae was performed colorimetrically using Folin-Ciocalteu and aluminum tri-chloride methods respectively. The concentration of total polyphenols expressed as Gallic acid equivalent (GAE) was 14 0.16 mg /g plant extract GAE, while the concentrations of flavonoids and flavonol contents expressed as rutin equivalent (RE) were 6.8 0.76 and 2.2 00 mg /g plant extract RE respectively. HPLC analysis of the total polyphenolic contents of aerial parts of the plant revealed the presence of eight compounds and pyrogallol was the highest concentration compound (1029.57 mg/100g dried plant powder), while HPLC analysis of total flavonoids showed the presence of three flavonoids and luteolin was the major compound (9.20mg/100g dried plant powder).GLC analysis of un-saponifiable matters (USM) of the aerial parts of the plant indicated the presence of n-triacontane (17.11%) , β-sitosterol (8.48%) and α-amyrine (14.35%) as the major hydrocarbon , sterol and triterpene respectively. GLC analysis of fatty acid methyl esters revealed that palmitic acid (12.179%) and oleic acid (54.297%) were the major saturated and unsaturated fatty acids respectively. GLC analysis of mucilage hydrolysate showed that glucose (46.1%) was the major component while fructose (0.34%) was the minor component. GC/MS analysis of the essential oil the leaves of Cotoneaster horizontalis Decne proved that the hydrocarbons represented (3.82%), while oxygenated compounds represented (62.25%). Benzaldehyde (34%) was the major constituent of the total volatile oil composition. The mucilage content of the aerial parts of Cotoneaster horizontalis Decne exhibited both hypoglycemic and anti-dyslipidemic effects at an oral dose of 250 mg/kg body weight (b.wt., p.o.).
