1. The effect of alpha-2A adrenergic receptor (ADRA2A) genetic polymorphisms on the depth of sedation of dexmedetomidine: a genetic observational pilot study
Abstract Background: The genetic polymorphisms of the alpha-2A adrenergic receptor (ADRA2A), which plays a significant role in sedation, anxiety relief, and antinociception, particularly in dexmedetomidine, may differ in the degree of sedation. This study aimed to investigate the effect of the genetic polymorphisms of ADRA2A (rs11195418, rs1800544, rs248451

2. Electrical stimulation of the posterior insular cortex induces opioid and cannabinoid-dependent antinociception and regulates glial cells in the spinal cord
RESUMO JUSTIFICATIVA E OBJETIVOS: Metade dos pacientes com dor neuropática são refratários aos tratamentos. A estimulação elétrica do córtex insular (EECI) posterior modula circuitos sensoriais e nociceptivos. Assim, este estudo avaliou os efeitos de uma faixa de frequências de EECI como tratamento em modelo animal de dor neuropática. MÉTODOS: Ra

3. Antinociceptive local effect of the combination of dexketoprofen trometamol and chlorhexidine gluconate in a formalin test: an additive effect
ABSTRACT A drug delivery system (DDS) with analgesic and antibacterial properties would be desirable for the local control of post-operatory pain and the prevention for surgical site infection (SSI). The objective of the present study was to evaluate the antinociceptive effect of the combination between dexketoprofen trometamol (DXT) and chlorhexidine glucon

4. Treatment with ascorbic acid and α-tocopherol modulates oxidative-stress markers in the spinal cord of rats with neuropathic pain
Vitamin E (vit. E) and vitamin C (vit. C) are antioxidants that inhibit nociception. The effect of these vitamins on oxidative-stress markers in the spinal cord of rats with chronic constriction injury (CCI) of the sciatic nerve is unknown. This study investigated the effect of intraperitoneal administration of vit. E (15 mg·kg-1·day-1) and vit. C (30 mg·

5. A spider derived peptide, PnPP-19, induces central antinociception mediated by opioid and cannabinoid systems
Abstract Background Some peptides purified from the venom of the spider Phoneutria nigriventer have been identified as potential sources of drugs for pain treatment. In this study, we characterized the antinociceptive effect of the peptide PnPP-19 on the central nervous system and investigated the possible involvement of opioid and cannabinoid systems in i

6. Possible mechanisms of antinociception of methanol extract of Melastoma malabathricum leaves
ABSTRACT Melastoma malabathricum L., Melastomaceae, has been traditionally used to relieve diverse pain-related ailments. The objectives of the present study were to determine the antinociceptive activity of methanol extract of M. malabathricum leaves and to elucidate the possible mechanisms of antinociception involved using various rats' models. The extract

7. Antinociceptive effect of semi-purified petroleum ether partition of Muntingia calabura leaves
ABSTRACT Muntingia calabura L., Muntingiaceae, is a medicinal plant for various pain-related diseases. The aims of the present study were to determine the antinociceptive profile and to elucidate the possible mechanisms of antinociception of petroleum ether partition obtained from crude methanol extract of M. calabura leaves using various animal models. The

8. Central release of nitric oxide mediates antinociception induced by aerobic exercise
Nitric oxide (NO) is a soluble gas that participates in important functions of the central nervous system, such as cognitive function, maintenance of synaptic plasticity for the control of sleep, appetite, body temperature, neurosecretion, and antinociception. Furthermore, during exercise large amounts of NO are released that contribute to maintaining body h

9. Acute stress-induced antinociception is cGMP-dependent but heme oxygenase-independent
Endogenous carbon monoxide (CO), which is produced by the enzyme heme oxygenase (HO), participates as a neuromodulator in physiological processes such as thermoregulation and nociception by stimulating the formation of 3′,5′-cyclic guanosine monophosphate (cGMP). In particular, the acute physical restraint-induced fever of rats can be blocked by inhibiti

10. Antinociceptive and anti-inflammatory activities of an aqueous extract of Chiliotrichum diffusum
The flowers of the Chiliotrichum diffusum (G. Forst.) Kuntze, Asteraceae, have long been used in traditional medicine and rituals. In this study, the anti-inflammatory and antinociceptive activities of a decoction of the flowers were evaluated and a phytochemical analysis was performed by HPLC-DAD. In order to evaluate the antinociceptive activity, the aceti

11. Atividade antinociceptiva e anti-inflamatória do sesquiterpeno nerolidol em camundongos. / Antinociceptive and anti-inflammatory activities of the sesquiterpeno nerolidol in mice.
Nerolidol, an acyclic sesquiterpene found as the major component in several essential oils, has antineoplastic, antimicrobial and antileishmanial activities, however its action in painful processes has never been studied. This study investigated the antinociceptive and anti-inflammatory activities of nerolidol in experimental pain and inflammation models in

12. Involvement of NK-1 receptors of the basolateral and central nuclei of the amygdala in the defensive behavior of rats / Participação dos receptores NK-1 dos núcleos basolateral e central da amígdala no comportamento defensivo de ratos
A substantial body of evidence obtained in the last decade demonstrated that the Substance P (SP) is an important mediator of the affective and emotional behaviors. SP is a pro-aversive compound when microinjected within the dorsal periaqueductal gray (dPAG). These effects are mediated by the type 1 neurokininergic receptors (NK-1), since the defensive behav
