Background: Pseudomonas aeruginosa is an opportunistic pathogen and a major cause of nosocomial infections. The aim of this study was to evaluate the frequency and determine the antimicrobial resistance in clinical strains of Pseudomonas aeruginosa isolated from different parts of Tehran hospitals in 2013.
Methods: In this cross-sectional study, during the six-month period, 180 samples were collected from different parts of eight hospitals in Tehran using of targeted sampling of the Modal Instance type. Biochemical tests were performed to identify the species and level of antibiotic-resistant in studied isolates by Kirby-Bauer disk diffusion susceptibility test protocol. The Chi-Square test was used for statistical analysis under the IBM SPSS 22 software.
Results: The 159 isolates of Pseudomonas aeruginosa (111 males and 48 females) were identified of 180 clinical samples. Strains isolated from wound (%44/1) and urine (%29/8) had the highest frequency. Also %97.5 of strains were hemolytic and only %2.5 were non- hemolytic (gamma hemolytic). The %88 of the isolates were resistant to at least one or more of an antibiotic. The Most antibiotic resistance was observed against cefotaxime (%62.9) and Aztreonam (%60.4) and %70 of strains were multiple drug resistance (MDR).
Conclusion: In this study, Pseudomonas aeruginosa strains showed the lowest resistance to imipenem that the antibiotic may be recommended as the main treatment option. The high prevalence of multidrug resistant strains, is a serious warning.

Abstract
Introduction: Cardiovascular diseases are the leading cause of morbidity, mortality and disability around the world. Education based on training models such as the health belief model is one of the most basic methods of prevention of diseases. The present study was conducted to determine the impact of teacher education based on the HBM model on promoting knowledge, attitude and performance of students in prevention of cardiovascular diseases.
Method: This interventional study was conducted on 78 first grade high school teachersand 467 of their students in the city of Dehloran during 2013-2014. Teachers were divided into two groups of intervention (n=41) and control (n=37) and students were also divided into two groups of intervention (n=249) and control (n=218). Intervention group teachers participated in 6 planned educational sessions based on the HBM model using teaching aids. Teachers completed questionnaires after 3 months and students after 6 months. Data was analyzed by SPSS software through descriptive tests, paired-t test and independent t-test.
Findings: The perceived benefits structure significantly changed for teachers in the prevention of cardiovascular disease (p <0.01). The performance of intervention group students significantly changed in prevention of cardiovascular diseases.
Conclusion: Educational intervention can be used as an effective factor in reducing risk factors of cardiovascular diseases in teachers and students through the HBM model from low ages.

Scleroderma- one of the important autoimmune diseases- leads to death of endothelial cells as one of the early events of this disease. The lack of repair after the loss of endothelial cells is observed in these patients and although, its cause has remained unknown. The development of effective treatments for many rheumatoid diseases requires a better understanding of the pathophysiological mechanisms involved in the disease. Because of physiological and anatomical and developmental differences between human and other species, a proper scleroderma animal model which represent all aspects of the disease has not been generated yet. So, making a patient-based system to mimic a developmental defect and evaluating its probable repair mechanism is considered as a necessity. For this reason, the development of a model system which can be an evaluation of molecular and developmental defects and also explain the possible repair mechanism, would be considered as a requirement. Like other studies, using patient-specific cell as a limitless source, could provide new hope for development of novel therapeutic approaches for patient with scleroderma.

Background: One of the most common foot problems is flat foot, which causes pain in the leg complex and postural control deficits. One way to treat flat foot is the use of therapeutic insoles. Insoles can change the distribution of load through the foot and ankle and decrease pain. The aim of this study was to (1) comparing dynamic balance of individuals with flat feet and healthy subjects (2) investigating the effect of insoles on dynamic balance in people with flat feet.
Methods: The participants in this study were 20 patients with flat foot and 20 healthy volunteers. The Star Excursion Balance Test was used to assess the dynamic balance. Analysis of variance (ANOVA) was used to determine any significant differences.
Results: The results showed that people with flat foot achievement in the Star Excursion Balance Test was significantly lower than healthy controls. In present study, use of therapeutic insoles in flat feet subjects, cause a significant increase in the scores of Star Excursion Balance Test (p<0.05).
Conclusion: The decrease of medial longitudinal arch imposed inappropriate distribution of stresses on the plantar fascia, joints and ligaments of the foot and ankle structures and thus will cause postural dysfunction in people with flat feet. Immediately after using therapeutic insole, dynamic balance will improve

Background: Apelin is a novel adipokine that is closely related with insulin resistance and type 2 diabetes. The purpose of the study was to determine the effects of progressive resistance training on plasma concentrations of plasma apelin and insulin resistance in middle-aged men with type 2 diabetes.
Methods: twenty seven types 2 diabetic men selected as subjects and were randomly assigned into two exercise (n=15 aged 46.40 ± 3.02 yrs) and control (n=12 aged 45.06 ± 3.86 yrs) groups. Resistance exercise training was done for 8 weeks (3 days/week, intensity: 30- 70% 1RM) for experimental group. Before and after exercise plasma apelin level, insulin,
glucose and insulin resistance (HOMA-IR) after a 12-h fasting was measured. Following the second blood sampling, data analysis was performed and p<0.05 was considered significant.
Results: Finding showed that plasma apelin, insulin levels, HOMA-IR, fasting blood glucose (FBG) have significant changes in the exercise group compared to pre-exercise and control groups (p≤0.05).
Conclusion: It seems that low to moderate intensity resistance exercise training has significant effect on the amount of plasma apelin and insulin resistance in type 2 diabetic men. Apelin level may be effective to improve insulin resistance and glycemic control in type 2 diabetic men.

Background: due to widespread applications of nanoparticles in biomedicine and biotechnology and their effects on human health, the present study was conducted to determine the cytotoxic effect of CuO nanoparticles on serum biochemical parameters and liver histopathological changes of NMRI mice. Methods: In this experimental study, forty two female NMRI mice were randomly divided into six groups (n=7): four experimental groups, one sham group and one control group. The experimental mice on days 3 and 12 of pregnancy received CuO nanoparticle with concentrations 300, 400, 500, 600 mg/kg intraperitoneally. After mentioned treatment, blood samples were collected and serum biochemical parameters were analyzed. On day 17 of pregnancy, mice were dissection and liver for histopathological evaluation were stained with hematoxylin and eosin. Results: Histopathological studies demonstrated dose-dependent changes in mice liver treated with CuO nanoparticles compared to control group. Some changes include congestion, necrosis, inflammatory cell infiltration, degeneration vacuoles were observed after exposure to different doses of CuO nanoparticles. The serum levels of ALT, AST, ALP and LDH enzymes increased significantly in a dose dependent manner as compared to the control group. Conclusion: The results of this study demonstrate that exposure to different doses of CuO nanoparticles can lead to irreversible damage to the liver and increased serum enzymes in NMRI mice.
