- چکیده:
- چکیده انگلیسی: In this study, the effectiveness of training close reading has been evaluated on reducing exam anxiety (reducing Social Credit, cognitive barriers and tension mode) of female students in the 8th grade. The research method was an experimental type. The statistical population of the research was female students of the 5th district of Tehran who was studying at the eighth grade during 2016-2017. The research sample included 40 students who were selected by cluster sampling method and they were randomly replaced in two groups. The fundamental techniques of close reading were trained to the experimental group in 8 sessions, while, the control group did not receive these trainings during this period. Then, anxiety exam was taken from the experimental group and controlling the anxiety of the above exam after the test. The results analyzed by using covariance analysis test (ANCOVA). Results showed that there was a significant difference (P≤0.05) between the experimental and control groups. Therefore, using close reading can lead to the reduction in exam anxiety.

- چکیده:
- چکیده انگلیسی: Cystic fibrosis-associated liver disease (CFLD) is an important aspect of cystic fibrosis (CF), which manifests with various signs and symptoms. Lack of specific examinations for CFLD have made the diagnostic process of the disease time-consuming, and the disease is often identified after severe progress. Finding the associations between the outcomes of various clinical, biochemical, and sonography examinations could help specialists identify the disease in a timely manner. This review study aimed to determine the correlations between the outcomes of various diagnostic approaches based on the current literature. According to the literature, some studies have reported correlations between various diagnostic approaches, while other studies have reported no associations in this regard. This discrepancy could be due to the various manifestations associated with CF.

- چکیده:
- چکیده انگلیسی: Introduction: Cystic fibrosis is one of the most common autosomal recessive diseases that affects sweat glands and mucosa. CF is a hereditary disease with annual incidence of about 2500 new cases in United Kingdom. Insulin-like growth factor-1 (IGF-1) and insulin-like growth factor binding protein-3 levels decrease in CF. The aim of this study was to assess the role of growth peptides in patients with CF.
Method: We searched PubMed, Google scholar, IranMedex, and Scientific Information Database (SID) in September 2012 to April 2014. We included clinical studies with available abstracts and full texts that were in English or Persian languages. Manual searching was conducted within the reference lists of articles. Two reviewers independently applied eligibility criteria, assessed quality, and extracted data.
Result: The earliest study was published in 1997 and the most recent one was in 2014. Study participants were adults in 3 studies (20%) and 12 studies (80%) were conducted in children. Patients with CF have lower levels of IGF-1 and there is a significant correlation between IGF-1 levels and growth index in patients with CF.
Conclusions: IGF-1 decreases in children with CF and might be the cause of poor growth and low body mass index in these children.- انتشار مقاله: 06-11-1393

- چکیده:
- چکیده انگلیسی: Introduction: Hepatopulmonary syndrome (HPS) is known as a chronic liver disease associated with severe pulmonary deoxygenation due to intrapulmonary vascular vasodilation. Although liver transplantation is accepted as a main treatment of HPS, identifying effective drugs for recovery of HPS can be effective in postponing the transplantation and decreasing the mortality rate of patients before the transplantation. In this study we briefly reviewed the pathogenesis of HPS and also systematically reviewed the current pharmacological treatment of HPS.
Method: Pubmed, Scopus, and Google scholar were searched for the relevant English language clinical and experimental articles about the medications used in the treatment of HPS.
Results: A total of 38 articles were included in this study which mostly resulted in decreasing NOS expression, NO production, endothelin-1 activation, intrapulmonary angiogenesis and increasing oxygenation.
Conclusion: Various drugs have been proposed in treatment of HPS but more large controlled trial studies, is necessary to determine the exact efficacy of each drugs for HPS recovery.- انتشار مقاله: 16-11-1392

- چکیده:
- چکیده انگلیسی: A novel rice-husk-silica supported n-propyl bipyridinium chloride (RHPrBPCl) has been prepared. Due to the basicity of RHPrBPCl, it was decided to evaluate its catalytic activity in the one-pot preparation of tetrahydrobenzo[b]pyran, dihydropyrano[3,2-c]chromene and dihydropyrano[4,3-b]pyran derivatives. The catalyst was characterized by FT-IR, SEM and TGA analyses. This methodology offers several advantages including easy work-up procedure, high yields of the products, short reaction times, recyclable catalyst and green reaction medium.

- چکیده انگلیسی: In the present study, application of porous acidic catalyst functionalized with an imidazole
ionic liquid ([SBA-Im]HSO4) as a phase transfer catalyst for the facile preparation of benzyl
thiocyanates and azides in water has been described. The catalyst has been characterized by
Fourier transform infrared spectroscopy (FT-IR), scanning electron microscope (SEM), transmission
electron microscopy (TEM), thermogravimetric analysis (TGA) and derivative thermogravimetric
analysis (DTG). The polymeric phase transfer catalyst, easily recovered by simple
filtration, shows no appreciable loss of activity when recycled several times.- انتشار مقاله: 04-03-1397

- چکیده:
- چکیده انگلیسی: The methodology involves preparing polyvinyl sulfuric acid as a solid acid by simple mixing of
polyvinyl alcohol with chlorosulfonic acid in CH2Cl2 at room temperature. The catalytic ability of
the solid acid was investigated for the facile conversion of benzylic alcohols to the unsymmetrical
ethers with aliphatic alcohols in the presence of the solid acid. Results show that the solid acid is
an appropriate catalytic agent for these condensation reactions. The silica was also extracted from
low-cost rice husk and the amorphous silica gel nanoparticles were prepared with sol- gel method.
The polyvinyl sulfuric acid was supported on nano rice husk silica. Then the catalytic effect of this
system was investigated for synthesis of unsymmetrical ethers which consisted of a combination of
high acidic power for this solid acid and high- surface area of nanoparticles. Results show that totally
catalytic effect of polyvinyl sulfuric acid supported on nano silica is more suitable than polyvinyl
sulfuric acid. The reason for this is in its ability to produce the end products in shorter reaction times
while having high isolated yields.- انتشار مقاله: 26-02-1396
