Background: learning style of students is one of the most important factors which influences on student learning. Some negative effects on nursing student learning can be observed as a result of imbalance between it and teaching methods. Using appropriate methods of teaching and determination of student learning styles can facilitate their leaning. Hence, this study aims to identify the most common learning styles of nursing students in Iran.
Materials and Methods: The Iranian databanks including Magiran, SID, Medlib and Iran Medex are searched for relevant published articles from March 21, 1991 till July 2012. For searching international databases, English transcriptions of Iran were used. The Persian search terms that were equivalent from their English words included Learning styles, nursing students and the Kolb learning style. It is noted that this review research only includes studies that are based on the Kolb's theory and researches that discuss other learning styles are excluded from the review process.
Results: Research articles that were based on the Kolb's theory of learning styles in entire of Iran has been collected and investigated. In all studies, learning styles of nursing students in several cities were searched for determining four styles of the Kolb's theory (Accommodating, Absorbent, Divergent and Convergent). The Convergent and Absorbing styles were dominant ones in the nursing students. These styles were ranged from 28.9% to 54.2% and 29.9% to 53.8%, respectively.
Conclusions: In order to enhance students learning more attention are required to different learning styles. It is recommended the teachers shall attract more attentions in students' learning style and use appropriate teaching methods.

Objective: Guidelines have recommended that structured programs to support fungal peritonitis in cancer patients should be introduced. The role of fungi in causing peritonitis is rare, but fungal peritonitis has high morbidity and mortality. The abdominal fullness may be secondary to the fungi accumulation of peritoneal fluid. The isolation of fungi, particularly Candida from peritoneal fluid samples in patients with cancer near abdominal region is an increasingly common occurrence that creates a hypothesis about the role of fungi as a pathogen or an innocent bystander in the disease process.
Methods: In this paper all the relevant papers about analysis of clinical signs, diagnosis and management fungal peritonitis in cancer patients particularly cancers near abdominal region were reviewed. An extensive search of texts published during 1950-2012 was undertaken by using identified key words and index terms.
Results: It seems that tumor-related local factors permit fungi to cross the gut wall and enter the peritoneum, and consequently the growth of fungi, inflammation and weakening of the immune system occurs in peritonitis. Due to the lack of specific clinical signs and difficulty of isolation of pathogenic organisms from clinical specimen treatment is very difficult.
Discussion: In malignant patients with inflammation of peritoneum, examination of peritoneal fluid for the fungal element (direct microscopic exam and culture) is necessary.

Introduction: Non-alcoholic fatty liver is one of the most prevalent digestive diseases in the world and its prevalence is increasing rapidly. The objective of this study was to compare the treatment effect of pioglitazone and metformin on fatty liver.
Materials and methods: This double blinded clinical trial study was performed in 2012 among patients referring to gastrointestinal clinics in the city of Ilam. 105 non-alcoholic fatty liver patients were selected and participated in this study. Patients were randomly divided into two groups of metformin and pioglitazone. Using double blinded clinical trial, one group was treated by pioglitazone (30 mg daily) and the other by metformin (500 mg daily) both for 3 months. Then using sonography, the severity of fatty liver was compared in the two groups.
Results: Multivariable logistic regression showed that there was no significant difference between the effect of pioglitazone and metformin on the treatment of fatty liver (p=0.92). There was a significant difference between severity of fatty liver and BMI before treatment (p<0.004) but it was not confirmed after the treatment. There was also a significant difference between the severity of fatty liver and gender before treatment (p<0.003) but it was not confirmed after treatment. There was a negative significant relationship between age and the treatment effect of metformin but not in the pioglitazone group.
Conclusions: Both pioglitazone and metformin had a notable effect on the treatment of fatty liver solely while there was no significant difference between their effectiveness. The effectiveness of metformin was higher among males compared to that of pioglitazone.

A novel, simple and more sensitive spectrophotometric procedure has been developed for the determination of Brilliant blue FCF and Carmoisine in food samples by an aqueous two-phase system (ATPS). After extraction, the absorbance values were measured at 527 and 632 nm for Carmoisine and Brilliant blue FCF, respectively. The effects of different parameters such as, polyethylene glycol (type and amount), pH, salt (type and amount), and temperature were investigated and optimum conditions were established. Linear calibration curves were obtained in the range of 0.1-120 ng mL-1 and 0.2-260 ng mL-1for Carmoisine and Brilliant blue FCF, respectively. Under optimum conditions, detection limit based on three times the standard deviation of the blank (3Sb) was 0.014 ng mL-1 for Carmoisine and 0.017 ng mL-1 for Brilliant blue FCF. The relative standard deviation (RSD) at concentration level of 30 ng mL-1 was 3.17% and 1.87% for Carmoisine and Brilliant blue FCF, respectively. The method was successfully applied to the determination of target analytes in spiked samples with satisfactory results.
