The aim of the present study was a comparison of radiofrequency bipolar cautery in tonsillectomy use. Methods: This clinical trial study was conducted on 33 patients older than 10 years-old candidate for tonsillectomy. Radiofrequency and Bipolar techniques were performed on the right and left tonsils of each studied patient, respectively. Data on pain, bleeding, operation duration and hardness was collected and analyzed by SPSS software, version 15. P-value less than 0.05 was considered statistically significant. Results: Bleeding volume did not statistically differ between two techniques while for other studied factors, statistically significant differences were observed in favor of radiofrequency method (P<0.05). The mean pain intensity in the Radiofrequency procedures on different days after surgery was significantly lower than that of bipolar cautery (P<0.05). Conclusion: Due to our results, the mean score of post-tonsillectomy pain was significantly less following radiofrequency technique in compare with bipolar technique.

One of the most important factors which is involved in pancreas development and transcription of insulin gene is pancreatic & duodenal homeobox 1 (PDX-1) transcription factor. The goal of this study was to optimize a lentiviral construct, containing pdx-1 gene, to transfect stem cells towards gene therapy of type-1 diabetes. Methods: In this experimental study, first, the pdx-1 gene was multiplied by PCR from pcDNA3.1-pdx-1 and cloned into pTG19-T vector. Then, pdx-1 was subcloned on upstream of IRES-EGFP gene into IRES2-EGFP vector. At the next step, the cloned parts of IRES-EGFP and pdx-1 were isolated and cloned into the lentiviral expression vector pSINTREM in upstream of TRE-CMV gene. After sequencing, final construct was transfected into HEK 293 cells and gene expression of pdx-1 was evaluated using flow cytometry analysis and reverse fluorescent microscopy. Results: Flow cytometry results and inverted fluorescent microscopy observing showed that pdx-1 and GFP genes are expressed in cells transfected with final recombinant construct. Conclusion: Regarding the design of this construct, to ensure long time expression with higher in vivo and in vitro expression efficiency for stem cells and also use of Tet on induced optimized system, it seems that the current construct can be among the best ones to transfect stem cells.
