Abstract
Background: Identifying the problems which exist in clinical education and setting to solve them will lead to the improvement of quality of medical care services. This study was conducted to fulfill this goal. Materials and Methods: In this descriptive–analytic research which was carried out in 2008, the views of the medical trainees and interns, who had at least gone through two major clinical courses at Arak University of Medical Sciences, about the obstacles of clinical education were evaluated. For achieving this purpose, a questionnaire containing 56 questions on 6 problem areas including clinical education spaces, educational facilities, cooperation of health and treatment personnel, clinical assessment and teaching methods, and clinical curriculum design methods was administered. Results: The quality of clinical education in the view of 41% of medical trainees and 48% of interns was seen to be at an average level. Assessment methods of clinical education, on the other hand, were rated as weak by 28.7% of trainees and 32% of interns. Also, 29.3% of trainees and 31.7% of interns evaluated the use of educational spaces to be at a weak level. Additionally, the quality of clinical teaching methods, educational facilities, cooperation of health and treatment personnel, and the design of clinical curriculum were seen at an average level. Conclusion: This study highlighted the importance of determining learning experiences, applying proper teaching methods, conducting continuous generative evaluations, using simulated environments and educational spaces congruent with graduates’ future employment opportunities, and enhancing students’ level of motivation, as effective strategies for the improvement of the quality of medical education.

Abstract
Background: One way of embryo preservation is cryopreservation, but this process may damage and lead to the loss of the embryos, and bring about chromosomal abnormality. This has led researchers to seek techniques for short term preservation of embryos in 0-10 ºC temperatures. The aim of this study was to determine the effect of short time exposure to 4°C temperature on the expression profiles of mono-carboxylic transporter genes 1,2 ,3, and 4(MCT1-4) in 4-cell mouse embryos. Materials and Methods: In this fundamental study, forty 4-cell mouse embryos from NMRI strain were randomly divided into two groups. The first group consisted of fresh 4-cell embryos, and the second group included 4-cell mouse embryos that were exposed to 4°C temperature for 24 hours. After RT-PCR, the samples were electro-phoresised for expressing the MTC1-4 genes. Results: The expression of MCT 1-3 was observed in the first group, but the obtained results did not indicate their expression in the second group. Conclusion: Preservation of 4-cell embryos in 4°C for 24 hours inhibits the expression of MCT 1-3 genes. Keeping embryos in 4°C temperature is not a proper way for their short time preservation.

Abstract
In the Holy Quran, it is stated that “eating honey has healing for people” “Fihe shefaho lenas”. The word “healing” in Quran has not been used about any other food but honey and one Sura in Quran is dedicated to Nahl (bee). This study investigates the importance of honey from the perspective of Quran and medicine. This review article investigated the therapeutic properties of honey from the perspective of Quran and medicine through text analysis and manual and online search. Medicine has proven that honey due to its low moisture, high osmosis, and high acidity inhibits the growth of infectious agents and creates a sterile coat on the wound. Prophet Mohammad said, “Lam yastashfeo almariz bemasale sharbato olasal”, meaning that nothing cures the sick person the way honey does. Studies have shown that honey is effective in strengthening child development and treatment, prevention, and improvement of skin, respiratory, liver, gallbladder, eyes, ears, and nose diseases and cancer. The application of natural honey to healing diabetic and cutaneous ulcers and the topical application of honey to open wounds can accelerate the healing process. Oral administration of dates honey syrup can enhance the natural progression of delivery and womb contractions which decrease the need for cesarean. It can be concluded from the review of the literature that emphasis of Quran on the use of honey in diet and its reference to the healing property of honey for people has not been without a cause. Modern medicine also verifies the curative properties of honey for many diseases.

Abstract
Background: Noticing the practical significance of stem cells, this study was conducted to culture and screen bone marrow mesenchymal stem cells derived from Raf and Hilline chicken strains and investigate the effect of age and race on the morphology and differentiation of the generated cells.
Materials and Methods: In this fundamental study, bone marrow cells from 3 to 25 day-old Raf and Hiline chicken strains were cultured in low glucose DMEM, 10% BFS. Then third passage bone marrow cells of the two strains were compared in terms of morphology, differentiation to bone, cartilage, and adiposity. Data were analyzed through SPSS software.
Results: In culturing Raf chicken derived bone marrow cells, in contrast to Hiline chicken strain, colonization took place and they almost had a better fibroblastic morphology. The results indicated higher yields of differentiation to bone, cartilage, and adipose tissues in Raf chicken derived bone marrow cells than Hiline chicken. These differences were statistically significant. Also, 15 days was the most suitable age for screening the mesenchymal stem cells of chicken.
Conclusion: Screening and proliferation of mesenchymal stem cells from 15-day old Raf chicken bone marrow cells are good resources for differentiation and purification of chicken bone marrow mesenchymal stem cells.

Abstract
Background: Occult hepatitis C virus (HCV) infection is defined as the presence of HCV-RNA in liver or peripheral blood mononuclear cells (PBMCs) in the absence of detectable hepatitis C antibody (anti-HCV) or HCV-RNA in the serum. Although occult HCV infection is less aggressive than classic chronic HCV infection, nevertheless it is important in management of hemodialysis (HD) patients. Occult HCV infection has been described in two different clinical settings: in patients with normal liver enzymes or in patients with abnormal values of liver enzymes. The aim of this study was to detect the occult HCV infection in hemodialysis patients with elevated liver enzymes.
Materials and Methods: This cross sectional study was performed in hemodialysis patients referring to 3 dialysis units in Tehran. In 30 anti-HCV negative HD patients with elevated liver enzymes, presence of HCV-RNA in plasma samples was tested by Reverse Transcriptase-Nested Polymerase Chain Reaction (RT-nested PCR). In cases with negative anti-HCV and plasma HCV-RNA, HCV-RNA was checked in PBMC specimens by RT-nested PCR.
Results: A total of 30 HD patients with mean age 54.4± 14.1years and mean dialysis duration 81.2 ±64.4 months were enrolled in the study. All HD subjects were negative for HCV-RNA in plasma and occult HCV infection with RT-nested PCR method.
Conclusion: Occult HCV infection was rare in HD patients with elevated levels of liver enzymes.

Abstract
Background and Aim Clostridium difficile is the main cause of Antibiotic-Associated Diarrhea (AAD) in the hospital setting. Today, the use of probiotics for the prevention and treatment of AAD and colitis is increasing. In this study, we investigated the effect of probiotic yogurt on the frequency of Clostridium difficile.
Methods and Materials In this randomized clinical trial study, 132 elderly patients admitted to the infectious ward of Vali-e-Asr Hospital in Arak, who were under antibiotic treatment, were randomly divided into two groups, case (yogurt probiotic, 200 mg/d for 8 days) and control group (common yogurt). All patients were trained about the signs of colitis. We evaluated the colitis signs and the presence of Clostridium difficile by Polymerase Chain Reaction (PCR) and compared them between the groups. The obtained data were analyzed with appropriate statistical tests in SPSS V. 16.
Ethical Considerations The Research Ethics Committee of Arak University of Medical Sciences approved this study (Code: 10-165-93). Also, it was registered at the Iranian Registry of Clinical Trials (Code: IRCT2016092229915N1).
Results Clostridium difficile was detected in 4 (6.1%) patients of the case, and 1 (1.5%) patient of the control group, at the beginning of the study. There was no significant difference between the frequency of Clostridium difficile and colitis syndrome between two groups at the end of the study (P>0.05).
Conclusion Probiotic yogurt has no significant effect in reducing the frequency of Clostridium difficile and colitis syndrome in our study.
