Abstract
Gastric Cancer (GC) is one of the most dangerous malignancies in the world. This study aims to evaluate the relationship between miR-146a and miR-155 in patients with H. pylori infections with GC compared to H. pylori-infected patients and healthy subjects. Forty patients with H. pylori and GC positive diagnoses and 40 patients with H. pylori positive and GC negative diagnoses, and 40 healthy persons were selected. The expression of miR-146a and miR-155 genes in the whole blood was examined using qRT-PCR. Moreover, ROC curves were drawn to represent the sensitivity and specificity of miR-146a and miR-155 expression as biomarkers. The results showed the expression of miR-146a and miR-155 in the whole blood of patients with H. pylori and GC positive diagnoses are significantly higher than in healthy individuals and are non-significantly enhanced compared to H. pylori positive and GC negative. Also, the results stated miR-146a and miR-155 expression in the whole blood of patients who are H. pylori positive and GC negative are significantly increased compared to healthy individuals. Furthermore, the ROC curve analysis of miR-146a and miR-155 RNA level demonstrated the two miRNAs have an appropriate sensitivity and specificity for diagnostic goals. In conclusion, H. pylori infection may increase the expression of miR-146a and miR-155 in patients with H. pylori and GC positive diagnoses, which can be effective in the curbing the progression of GC. For this reason, up-regulation of miR-146a and miR-155 along with H. pylori infection might contribute to the pathogenesis of GC, and also can be suggested as biomarkers for GC diagnosis and treatment.

Abstract
BACKGROUND & AIM Cell-based therapy utilizing mesenchymal stem cells (MSCs) is currently being investigated as a therapeutic agent for chronic wounds. There is no evidence regarding effectiveness of the spray and local transfer of this cellular product in diabetic wound healing. Accordingly, the present study, using clinical, pathological and biometric parameters, investigated the effectiveness of the spray of these cells in the healing of diabetic wounds in rats. METHODS Three days after the induction of diabetes (50 mg/kg single dose of streptozotocin) a circular excision was created on the back of rats. Diabetic rats were divided into two groups (n=21): Control and WJ-MSCs group. Sampling of the studied groups was performed on days 7, 14 and 21 after wounding. Histological, ultrasound imaging of dermis and epidermis in the wound area for thickness and density measurement and skin elasticity were evaluated. RESULTS Our results on days 7, 14, and 21 after wounding showed that the wound closure, thickness and density of new epidermis and dermis, as well as skin elasticity in healed wound were significantly higher in WJ-MSCs group compared to the Control group. CONCLUSION Application of WJ-MSCs suspension spray on the wound area can accelerate healing in diabetic wounds. Our findings may potentially provide a helpful therapeutic strategy for patients with a diabetic wound.

Abstract
Introduction: The efficiency of stem cell isolation, culture, and biological characterization techniques for treatment is facing serious challenges. The purpose of this study was to provide a protocol for isolation and culture of three types of mesenchymal stem cells (MSCs) derived from the human placenta, amniotic membrane, and umbilical cord with high efficiency used for cell therapy. Methods: During this experimental laboratory study, 10 complete placenta samples were prepared from cesarean section mothers. The protocol for isolation and culture of mesenchymal cells from the placenta tissue, umbilical cord, and amniotic membrane was enzymatically optimized. The morphological features of mesenchymal cells were investigated using an inverted microscope and their biological features were measured using flow cytometry. The differentiation potential of the cells was evaluated by measuring their differentiation capacity into osteocytes and adipocytes. The absorption and reflectance features of the cells were recorded by optical spectroscopy. Finally, the data were statistically analyzed. Results: The expression of CD44, CD73, CD90 and CD29 markers in human placenta tissue-derived cells was significant. CD14, CD34 and CD45 markers were not expressed or were slightly expressed. These cells were highly viable and successfully differentiated into osteocytes and adipocytes. MSCs absorbed more light than visible light by showing light absorption peaks at wavelengths of about 435 and 550 nm. Conclusion: The protocol used in this study for isolation and culture of human placenta tissue-derived MSCs had significant efficiency for the production of MSCs for use in cell therapy and tissue engineering.

Abstract
OBJECTIVE Alcoholic hepatitis (AH) is a type of alcoholic liver disorder caused by overconsumption of alcohol. The involvement of several transcription factors (TF), as the main regulators of disease related gene expression has been documented previously. However, despite the importance of analysis of gene regulatory network for understanding the molecular basis in any disease, so far, there is no report on construction of such network for AH in human. MATERIALS AND METHODS Here, we used microarray analysis to construct a rather complete gene regulatory network and used it to predict TFs and pathways that affected by this disease. RESULTS Ten TFs were shown to undergo significant alteration in AH. These TFs are AR, EGR1, MYC, TCF4, ATF3, JUN, FOXO3, STAT1, HIF1A and EOMES, where ATF3, TCF4 and MYC are the new TFs with a role in AH. Comparisons of gene expression profile of patients with those of healthy persons indicates 820 differentially expressed (DE) genes. Network analysis indicates that, these ten TFs regulate expression of 516 DE genes (out of 820 genes), by 1057 interactions. Furthermore, we report pathways that significantly affected by these ten TFs. CONCLUSIONS These results may contribute to our limited understanding of the molecular basis of AH.
