Endothelium-dependent constriction in mouse pial arterioles was demonstrated by testing contractile responses before and after endothelial injury. All responses were monitored at the same site as the injury. Injury was produced in vivo by exposing an arteriole on the brain surface to the beam of a 6-mW helium-neon laser after first sensitizing the microvascular bed to the laser energy by inject...

Introduction: Peripheral and central nerve injuries cause chronic neuropathic pain in many injured people besides motor disability. Exercise, as a behavioral and non-pharmacological treatment, has beneficial effects on people’s general health both for healthy and sick people. Therefore, this study was conducted to examine the effects of exercise on neuropathic pain induced by chronic cons...

Treatment of neuropathic pain is still a major challenge because of its noresponsiveness to most available pharmacotherapy. Curcumin has been reported to play an active role in the treatment of various neurological disorders, such as neuropathic pain. In this study, the role of curcumin has been evaluated in pain behavioral responses of chronic Constriction injury (CCI) in rat. In this experime...

Background Chronic orofacial pain conditions such as trigeminal neuropathic pain, reflex sympathetic dystrophy of the face, and temporomandibular pain disorders are debilitating pain conditions. They are known to respond poorly to treatment including opioids in human patients. There is a pressing need to better understand the mechanisms of these chronic orofacial pain conditions so that new and...
