Abstract
Background: Many researches have been conducted on islet cells' transplantation for a definitive treatment of diabetes mellitus type1. As the viability of the islets is the most important factor in predicting the transplantation prognosis, we have designed a study to isolate rat's islets. The aim of the study was to assess the viability of the islets at different stages and suggest the best transplantation time.
Methods: Pancreatic islets were isolated from male rats (250-300gr) by standard surgical procurement followed by intraductal HBSS distension, chopping and digestion with collagenase (type V). After being centrifuged for 3 times, the islets were then hand-picked and incubated in 37oC with RPMI 1640 media for 6 days. Each well contained 35-45 islets. Viability of islets was assessed by 2 independent investigators, giving score 0-2 to the color of islets under florescent microscope after Propidium iodide/Acridine orange staining at 6 times: just after the incubation, 24h, 48h, 3rd day, 5th and 6th day.
Results: The viability of the islet cells was gradually increased after the incubation as we had the most viability rate after the second day, while it decreased after this period and reached the least rate on the 5th and 6th day.
Conclusion: The islets' viability increased following the cell culture after the isolation procedure, as they have the best condition for transplantation after 48 hours. As the islets’ viability is the most critical point in transplantation, further studies evaluating the effects of different interventions on viability is needed.

Abstract
Background: Glucose metabolism impairment may occur during some pregnancies especially of advanced age and history of previous gestational diabetes and may result in hazardous consequences both for mother and neonate.
Methods: The present study as a case-control was conducted on 420 referred pregnant women to Shiraz hospitals that involve 70 diabetic patients and 350 non-diabetic women. Data analyzed by analysis of variance and χ square for univariate and logistic regression for multivariate analysis.
Results: From 70 diabetic patients 22(31.4%) afflicted with overt diabetes as well as 48 (68.6%) gestational diabetes. Gestational diabetes history (OR=23.14), hydramnious (OR=13.26), glucosuria at 3rd trimester (OR=11.49), family history of diabetes (OR=4.09) and age (OR=1.03) were the most important risk factors for gestational diabetes, respectively. History of macrosomia in previous pregnancies (OR=18.83) and history of previous cesarean section (OR=11.96) were the most important predictors for overt diabetes.
Conclusion: In view of several threatening consequences of diabetes during pregnancy, screening for diabetes especially in mothers with gestational diabetes history and family history of diabetes is essential in order to control and prevention of these outcomes in mother and neonate.

Abstract
Background: Gestational diabetes in on of common complications of pregnancy which has different complications for fetus and mother. Aim of present study was to review the effect of six weeks aqua training in second trimester of pregnancy on visfatin and glucose tolerance of gestational diabetic women.
Methods: In this semi experimental research 24 gestational diabetic mothers who recourse to hafez clinic of shiraz city which were in 23- 24 week of pregnancy select as sample and divided in two groups of 12 persons of aqua training and control. Aqua training group trained aqua trainings 6 weeks, 3 sessions per week and 45 minutes per session. In this period of the time control group has just their daily activities. For measure the research variables fasting blood sample gathered from antecubital vein in pretest and post test.
Results: Six weeks aqua training in second trimester of pregnancy has significant effect on increase of visfatin and decrease of glucose tolerance of gestational diabetic women (p=0.001).
Conclusion: It seems that for improvement of visfatin levels and glucose tolerance of gestational diabetic women can use six weeks aqua training in second trimester of pregnancy.

Abstract
Background: The prevalence of type 2 diabetes is rapidly increasing in the world. As a result of this disease, long-term insulin resistance develops, as a result of which pancreatic beta cells are destroyed and disappear, as a result insulin is not released. Recently, a protein called lipasin, which is responsible for signaling the liver to beta cells, has been discovered, and previous reports have shown that lipasin/betatrophin increases pancreatic β cell proliferation. Therefore, the aim of this study was to investigate the effect of eight weeks of high intensity interval training (HIIT) and endurance training on lipasin gene expression in rats with type 2 diabetes.
Methods: The study was performed on 25 Wistar rats with a mean weight of 160±10 g and age of 8 weeks. After induction of diabetes, the rats were randomly divided into three groups of 6: control and endurance and HIIT. And exercise was performed for eight weeks (5 sessions per week). QRT-PCR technique was used to evaluate changes in hepatic lipasin gene expression.
Results: The present study showed that after eight weeks of endurance training and HIIT, the expression of lipasin gene in the liver of rats in the training group increased significantly compared to the control group (P = 0.037); Also, a significant negative correlation was observed between lipasin gene expression and insulin resistance index in the exercise group compared to the control group (r = -0.605, P = 0.037).
Conclusion: It seems that performing eight weeks of endurance training and HIIT, by increasing the expression of lipasin gene can increase beta cells in diabetic patients and may be an effective non-pharmacological intervention to reduce the symptoms of this disease.
