Animal Models of Nociception [PDF]
The study of pain in awake animals raises ethical, philosophical, and technical problems. We review the ethical standards for studying pain in animals and emphasize that there are scientific as well as moral reasons for keeping to them. Philosophically, there is the problem that pain cannot be monitored directly in animals but can only be estimated by ...

A review on hydrogen sulfide: Is it pro-nociceptive or anti-nociceptive?
Pain is sensed by the activation of painful nociceptors in the periphery or by pain mediators, such as bradykinin, serotonin, histamine, and prostaglandin, released from the damaged tissue, afferent transmission to the medulla spinalis, and by trans- mission stages to the high centers over the dorsal horn. Pain, which was seen as only a warning sign in

Pain detection with bioimpedance methodology from 3-dimensional exploration of nociception in a postoperative observational trial [PDF]
Although the measurement of dielectric properties of the skin is a long-known tool for assessing the changes caused by nociception, the frequency modulated response has not been considered yet.

Capsaicin, Nociception and Pain [PDF]
Capsaicin, the pungent ingredient of the hot chili pepper, is known to act on the transient receptor potential cation channel vanilloid subfamily member 1 (TRPV1). TRPV1 is involved in somatic and visceral peripheral inflammation, in the modulation of nociceptive inputs to spinal cord and brain stem centers, as well as the integration of diverse ...

Optogenetics and photopharmacology in pain research and therapeutics
Pain afflicts billions of people worldwide, who suffer especially from long-term chronic pain. This gruelling condition affects the nervous system at all levels: from the brain to the spinal cord, the Dorsal Root Ganglia (DRG) and the peripheral fibres ...

The ankyrin repeat domain of the TRPA protein painless is important for thermal nociception but not mechanical nociception. [PDF]
The Drosophila TRPA channel Painless is required for the function of polymodal nociceptors which detect noxious heat and noxious mechanical stimuli. These functions of Painless are reminiscent of mammalian TRPA channels that have also been implicated in ...

Mechanisms underlying cardiac pain are of major importance in cardiovascular medicine. In this review we address a fundamental clinical and experimental aspect. In particular neural circuitry involved justify a stepwise involvement of central structures responsible of reflex adjustments initiated by peripheral ischemia that can be associated with pain ...

Leptin and fractalkine: novel subcutaneous cytokines in burn injury
Burn injury is a pathology underpinned by progressive and aberrant inflammation. It is a major clinical challenge to survival and quality of life. Although the complex local and disseminating pathological processes of a burn injury ultimately stem from ...

Divergent modulation of nociception by glutamatergic and GABAergic neuronal subpopulations in the periaqueductal gray [PDF]
The ventrolateral periaqueductal gray (vlPAG) constitutes a major descending pain modulatory system and is a crucial site for opioid-induced analgesia. A number of previous studies have demonstrated that glutamate and GABA play critical opposing roles in

Background: Sensory neurons play an essential role in almost all pain conditions, and have recently been classified into distinct subsets on the basis of their transcriptomes. Here we have analysed alterations in dorsal root ganglia (DRG) gene expression
