A total of 104 elderly were included in the longitudinal clinical study and were attributed to the diabetes group (n = 30) and the non-diabetic group (n = 29). Both groups were involved in the aquatic exercise (nine exercises; 3 sets x 1-minute duration each; linear intensity and frequency measured twice a week) for 12 weeks.

The existing therapies for MS are only partially effective and are associated with undesirable side effects. Low-level laser therapy (LLLT) has been clinically used to treat inflammation, and to induce tissue healing and repair processes.

Male Wistar rats received saline or saline containing CG administered into the pleural cavity, and some rats also received NAC (20 mg/kg) subcutaneously and/or AuNP administered into the pleural cavity immediately after surgery. Four hours later, the rats were sacrificed and pleural exudates obtained for evaluation of cytokine levels and myeloperoxidase activities.

Wistar rats performed 21 d of exercise on a treadmill at different intensities and were exposed to ultrasound in the presence or absence of AuNPs. The overuse model promoted behavioral changes and increased creatine kinase, superoxide dismutase and glutathione peroxidase activity, as well as the levels of superoxide, nitrotyrosine, nitric oxide, thiobarbituric acid reactive substance, carbonyl, tumor necrosis factor α and interleukin-6.

When the intensity of exercise fluctuates between mild and moderate, it improves the status of reduction-oxidation balance in the brain and induces neuroplasticity. However, intense exercise can oxidize the brain and impair neurological function.

Studies have shown an exacerbated increase in proinflammatory markers during and after muscle injury. In this way, interventions that reduce inflammatory activation appear to be of great interest in muscle injury therapy. Thus, the preset study evaluated the effect of low-intensity pulsed ultrasound (LIPUS) and dimethylsulfoxide (DMSO) on the proinflammatory molecules in an animal model of traumatic muscle injury.

It has been demonstrated that reactive oxygen species (ROS) formation and oxidative damage markers are increased after muscle damage. Recent studies have demonstrated that low-level laser therapy (LLLT) modulates many biochemical processes mainly those related to reduction of muscular injures, increment of mitochondrial respiration and ATP synthesis, as well as acceleration of the healing process. The objective of the present investigation was to verify the influence of LLLT in some parameters of muscular injury, oxidative damage, antioxidant activity, and synthesis of collagen after traumatic muscular injury.
