“Prostaglandin E(2) (PGE(2)) is a key mediator of exaggerated pain sensation during inflammation. Drugs targeting the PGE(2) pathway by global inhibition of cyclooxygenases are well established
in the treatment of inflammatory pain, but also cause significant unwanted effects. Enzymes downstream of the cyclooxygenases, or prostaglandin receptors are candidate targets possibly enabling therapeutic intervention with potentially fewer side effects. Among the PGE(2) receptors, the EP1 subtype has repeatedly been proposed as a promising target for treatment of inflammatory hyperalgesia. However its involvement in sensitization at specific (peripheral or central) sites has not been thoroughly investigated. Here, we have used mice deficient in the EM receptor (EP1(-/-)) to address this issue. EP1(-/-) mice showed normal mechanical and heat sensitivity during baseline conditions. Local subcutaneous PGE(2) injection into one hindpaw, caused thermal and mechanical sensitization in wild-type mice and EP1 mice. Thermal sensitization in EP1(-/-) mice was less than in wild-type mice while no significant difference was seen for mechanical sensitization. Injection of PGE(2) into the subarachnoid space of the lumbar spinal cord, resulted in a similar mechanical
sensitization in EP1(-/-) mice and in wild-type mice, while a tendency towards reduced reaction to noxious heat stimulation was observed in EP1(-/-) mice. These results support a major contribution of EP1 selleck chemical receptors to peripheral heat sensitization, but only a minor role in mechanical sensitization and in spinal heat sensitization by PGE(2). After local subcutaneous zymosan A injection, EP1(-/-) mice showed indistinguishable mechanical and heat sensitization compared with wild-type mice. Taken together, these results suggest that peripheral EP1 receptors contribute significantly to inflammation induced heat pain sensitization while evidence for a contribution to central sensitization
was not obtained. (C) 2011 Elsevier Ireland Ltd. All rights reserved.”
“Attention and executive SNS-032 research buy functions show strong associations with slow gait and falls in seniors and have been shown to be amenable to cognitive remediation. However, cognitive remediation as a strategy to improve mobility has not been investigated.
Using a randomized single-blind control design, 24 sedentary older adults (exercise less than or equal to once weekly and gait velocity < 1 m/s) were randomly assigned to an 8-week computerized cognitive remediation program or wait-list. Primary outcome was change in gait velocity during normal pace and “”walking while talking”" conditions. We also compared the proportion of improvers (velocity change >= 4 cm/s) in each group.
The 10 participants who completed cognitive remediation improved gait velocity from baseline during normal walking (68.2 +/- 20.0 vs 76.5 +/- 17.9 cm/s, p = .
