Duchenne muscular dystrophy (DMD) is characterized by progressive muscle necrosis. One of the major challenges for prescribing physical rehabilitation exercises for DMD patients is associated with the lack of a thorough knowledge of dystrophic muscle responsiveness to exercise. This study aims to understand the relationship between myogenic regulation, inflammation and oxidative stress parameters, and disease progression induced by downhill running in the skeletal muscle of an experimental model of DMD.

Methods: A total of 24 male Wistar rats were distributed into the following groups, as follows: Group 1-Control (CTRL; n = 8); Group 2-Sleep deprivation (PS; n = 8): the animals were submitted to Paradoxical Sleep deprivation for 96 h and Group 3-Recovery (R; n = 8): the animals were submitted to sleep loss for 96 h, followed by a period of 96 h without any intervention. The following parameters were evaluated: microscopic analysis, immunohistochemistry for Caspase-3, Ki-67, and COX-2 and gene expression of cytochrome C, TNF-α, and Interleukins 6, 10.

The aim of this study was to evaluate if paradoxical sleep deprivation is able to induce tissue degeneration, inflammatory activity and apoptosis in the submandibular gland of rats. A total of 24 male Wistar rats were distributed into the following groups: group 1-control (CTRL; n = 8): the animals were not submitted to any procedures; group 2-sleep deprivation (PS; n = 8): the animals were submitted to paradoxical sleep deprivation for 96 h and group 3-recovery (R; n = 8): the animals were submitted to sleep deprivation for 96 h, followed by a period of 96 h without any intervention. The following parameters were evaluated: histopathological analysis, immunohistochemistry for Ki-67, COX-2 and cleaved caspase-3 and gene expression of TNF-α, Interleukin 6 (IL-6), Interleukin 10 (IL-10) and cytochrome C by real-time PCR.
