The importance of the modulation of pain by emotion is now widely recognised. In particular, stress and anxiety, depending on their nature, duration and intensity, can exert potent, but complex, modulatory influences typified by either a reduction or exacerbation of the pain state. Exposure to either acute or chronic stress can increase pain responding

The effect of psychological manipulations on the development of secondary hyperalgesia: a critical review [PDF]
. As central sensitization is believed to contribute to persistent pain and psychological factors are increasingly acknowledged to play a role as well, the question arises of whether psychological factors can modulate the development of central ...

Acute phenobarbital administration induces hyperalgesia: pharmacological evidence for the involvement of supraspinal GABA-A receptors [PDF]
The aim of the present study was to determine if phenobarbital affects the nociception threshold. Systemic (1-20 mg/kg) phenobarbital administration dose dependently induced hyperalgesia in the tail-flick, hot-plate and formalin tests in rats and in the ...

Modulating AMPA receptor-dependent synaptic plasticity: Mechanistic interventions against remifentanil-induced hyperalgesia in reoperative rats – A randomised controlled trial [PDF]
Background and Aims: Intraoperative remifentanil can induce postoperative hyperalgesia. In clinical practice, either unplanned or planned second operations may occur within a short period.

An improved model of heat-induced hyperalgesia--repetitive phasic heat pain causing primary hyperalgesia to heat and secondary hyperalgesia to pinprick and light touch. [PDF]
This study tested a modified experimental model of heat-induced hyperalgesia, which improves the efficacy to induce primary and secondary hyperalgesia and the efficacy-to-safety ratio reducing the risk of tissue damage seen in other heat pain models ...

Neurotrophins and hyperalgesia [PDF]
Nerve growth factor (NGF), a member of the neurotrophin family, is crucial for survival of nociceptive neurons during development. Recently, it has been shown to play an important role in nociceptive function in adults. NGF is up-regulated after inflammatory injury of the skin.

Orthodontic tooth movement elicits alveolar bone remodeling and orofacial pain that is manifested by tooth mechanical hyperalgesia. Nerve growth factor (NGF) is upregulated in periodontium and may modulate tooth mechanical hyperalgesia.

Evaluation of the Effect of (S)-3,4-Dicarboxyphenylglycine as a Metabotropic Glutamate Receptors Subtype 8 Agonist on Thermal Nociception Following Central Neuropathic Pain [PDF]
Study Design In this study, we decided to change the activity of periaqueductal gray (PAG)'s metabotropic glutamate receptors subtype 8 (mGluR8) by means of its specific agonist, (S)-3,4-dicarboxyphenylglycine (DCPG), and by knock downing it with mGluR8 ...

The connection of monocytes and reactive oxygen species in pain. [PDF]
The interplay of specific leukocyte subpopulations, resident cells and proalgesic mediators results in pain in inflammation. Proalgesic mediators like reactive oxygen species (ROS) and downstream products elicit pain by stimulation of transient receptor ...
