There is a lack of information based on clinical data to guide clinical judgement in identifying cases where aggressive canine behaviour could be related to pain. This study aimed to identify clinical themes in cases of aggressive behaviour by dogs in which a relevant painful focus was identified versus a control group with similar initial presenting problems, in which no medical complications ...

Chronic itch in atopic dermatitis is a significant clinical problem with unmet needs. Pain also common symptom of dermatitis. Crisaborole, PDE-4 inhibitor, approved for the treatment mild to moderate The inhibitor appears reduce by activating cAMP-PKA pathway. However, mechanism underlying this antipruritic effect has not fully understood. mouse model was developed repeatedly applying MC903. Cr...

BACKGROUND Our goal is to use gene therapy to alleviate pain by targeting glial cells. In an animal model of facial pain we tested the effect of transfecting the glutamic acid decarboxylase (GAD) gene into satellite glial cells (SGCs) of the trigeminal ganglion by using a serotype 5 adenovector with high tropisms for glial cells. We postulated that GABA produced from the expression of GAD would...

Accumulating evidence indicates that increased generation of reactive oxygen species (ROS) contributes to the development of exaggerated pain hypersensitivity during persistent pain. In the present study, we investigated the antinociceptive efficacy of the antioxidants vitamin C and vitamin E in mouse models of inflammatory and neuropathic pain. We show that systemic administration of a combina...

We hypothesize that changes in motor behavior in individuals with low-back pain are adaptations aimed at minimizing the real or perceived risk of further pain. Through reinforcement learning, pain and subsequent adaptations result in less dynamic motor behavior, leading to increased loading and impoverished sensory feedback, which contribute to cortical reorganization and proprioceptive impairm...

Background: Evidence indicates that neuropathic pain pathogenesis is not confined to changes in the activity of neuronal systems but involves interactions between neurons, inflammatory immune and immune-like glial cells. Substances released from immune cells during inflammation play an important role in development and maintenance of neuropathic pain. It has been found that minocycline suppress...

BACKGROUND EphB receptors and their ephrin-B ligands play an important role in nervous system development, as well as synapse formation and plasticity in the adult brain. Recent studies show that intrathecal treatment with EphB-receptor activator ephrinB2-Fc induced thermal hyperalgesia and mechanical allodynia in rat, indicating that ephrin-B2 in small dorsal root ganglia (DRG) neurons and Eph...

Slack (Slo2.2) is a sodium-activated potassium channel that regulates neuronal firing activities and patterns. Previous studies identified Slack in sensory neurons, but its contribution to acute and chronic pain in vivo remains elusive. Here we generated global and sensory neuron-specific Slack mutant mice and analyzed their behavior in various animal models of pain. Global ablation of Slack le...

Recent behavioral research suggests that empathic behaviors may not be limited to humans and higher-order primates. In mice, pain directed behavior appears to be modulated based on the presence and pain status of a conspecific. However, additional indicators of social attachment have yet to be demonstrated in the mouse model. The present study attempts to determine if mice exhibit additional em...
