Manganese-enhanced magnetic resonance imaging depicts brain activity in models of acute and chronic pain: a new window to study experimental spontaneous pain? (2017)
Journal Article

Application of functional imaging techniques to animal models is vital to understand pain mechanisms, but is often confounded by the need to limit movement artefacts with anaesthesia, and a focus on evoked responses rather than clinically relevant sp...

Inhibitory effects of aspirin-triggered resolvin D1 on spinal nociceptive processing in rat pain models (2016)
Journal Article

Background Harnessing the actions of the resolvin pathways has the potential for the treatment of a wide range of conditions associated with overt inflammatory signalling. Aspirin-triggered resolvin D1 (AT-RvD1) has robust analgesic effects in behav...

Robust anti-nociceptive effects of MAG lipase inhibition in a model of osteoarthritis pain (2016)
Journal Article

BACKGROUND AND PURPOSE: Chronic pain is often a symptom of knee osteoarthritis (OA) for which current analgesics are either inadequate, or are associated with serious side effects. The endocannabinoid system may offer alternative targets for pain-rel... Read More about Robust anti-nociceptive effects of MAG lipase inhibition in a model of osteoarthritis pain.
