Abstract
Background: Peripheral neuropathy is a common complication associated with diabetes mellitus. It has been shown that oxidative stress is an important etiological factor in neuropathy which contributes to its development however, the exact pathophysiology underlying this complication is not fully understood. This study was designed to examine the effect of regular exercise and vitamin C administration on pain threshold in rats. Materials and Methods: In this experimental study, 36 male Wistar rats (220±10 g) were allocated to control and diabetic (control, vitamin C, exercise, and exercise+ vitamin C) groups. Diabetes was induced by the subcutaneous administration of streptozotocin (60 mg/kg). A week after the induction of diabetes, the rats were subjected to swimming training and vitamin C treatment for 8 weeks. At the end of weeks 3, 5, and 8, Tail-Flick test was done on the rats to assess pain threshold. Data were analyzed using SPSS software. Results: Diabetes significantly decreased pain threshold in the rats. Diabetes-induced hyperalgesia was significantly decreased by training and vitamin C. Concurrent effects of training and vitamin C on thermal pain threshold were significantly higher than each of them alone. Conclusion: Regular exercise together with vitamin C administration can be a proper method for preventing thermal hyperalgesia associated with diabetes. Therefore, they can be effective in the treatment and management of pain

Abstract
Background and Aim: Research has shown that social power affects information processing in many ways and can induce powerful movements or gestures. This study aimed to investigate the effect of pretending power gestures on changing the pain threshold of a group of female students.
Methods & Materials: The method of the present study was quasi-experimental with a pre-test post-test design with a control group. The statistical population of this study included all female students of Arak University in the academic year 2016-2017, from which 60 people selected by convenience sampling method, and randomly divided into three groups: high power posing (sitting on a chair and putting your feet on the table, placing your hands behind your head and holding your head up), low power posing (sitting on a chair with your legs together, arms between your legs and bending your head to bottom) and control. Rosenberg self-esteem scale and tourniquet technique with cuff pressure gauge (to measure pain threshold) used to collect data. After the pre-test measurements and two minutes of gestures, the post-test was performed immediately. Data were analyzed using the analysis of covariance.
Ethical Considerations: This study was approved by the ethics committee of Arak University of Medical Sciences (Code: IR.ARAKMU.REC.1399.276).
Results: The results showed that pretending high/low power gesture significantly affects pain threshold; pretending to have a high-power gesture increases the pain threshold, and pretending to have a low-power gesture lowers the pain threshold.
Conclusion: Based on the results, using power gestures as a simple tool in pain situations is recommended for pain management or as a supplement to analgesics.
