Efecto de una dosis de lidocaína y ketamina sobre el consumo intraoperatorio de opioides en pacientes sometidas a cirugía ginecológica electiva bajo anestesia general. Estudio piloto aleatorizado y controlado con placebo [PDF]

open access: yes, 2016
Background and goal of study: there is evidence that perioperative intravenous ketamine and lidocaine reduce postoperative pain, postoperative opioids consumption, shortens hospital stay and accelerates intestinal function recovery.

Nociceptin attenuates the escalation of oxycodone self-administration by normalizing CeA-GABA transmission in highly addicted rats. [PDF]

open access: yes, 2020
Approximately 25% of patients who are prescribed opioids for chronic pain misuse them, and 5 to 10% develop an opioid use disorder. Although the neurobiological target of opioids is well known, the molecular mechanisms that are responsible for the ...

Cancer pain: current practice and emerging targets

open access: yesBritish Journal of Pharmacology, EarlyView.
Cancer pain (CP) arises from a complex interplay between the tumour and its microenvironment. Many patients experience a mixed pain phenotype that encompasses nociceptive, neuropathic and neuroinflammatory mechanisms, and vary across tumour type and disease stage. Despite decades of intensive research, the mainstay of cancer pain treatment is still non‐

The Regulatory Mechanisms and Therapeutic Potential of MicroRNAs: From Chronic Pain to Morphine Tolerance

open access: yesFrontiers in Molecular Neuroscience, 2018
Chronic pain, including cancer-related pain, is a pain condition often caused by inflammation or dysfunctional nerves. Chronic pain treatment poses a significant health care challenge, where opioids especially morphine are widely used and patients often ...

Surgical excision of melanomas in the anal region and reconstruction of the anus in 11 horses

open access: yesEquine Veterinary Education, EarlyView.
Summary This case report describes the surgical excision of large perianal and perineal melanomas, and reconstruction of the anus in 11 grey horses. Four horses had a history of painful defaecation or urination due to extensive tumours. Seven horses had no clinical signs at the time of admission but had rapidly growing nodules around the anus with ...

Dopamine D4 receptor counteracts morphine-induced changes in M opioid receptor signaling in the striosomes of the rat caudate putamen. [PDF]

open access: yes, 2015
Morphine is one of the most potent analgesic drugs used to relieve moderate to severe pain. After long-term use of morphine, neuroadaptive changes in the brain promotes tolerance, which result in a reduced sensitivity to most of its effects with ...

Surgical removal of a perirectal melanoma through sphincterotomy and rectal wall resection in a horse

open access: yesEquine Veterinary Education, EarlyView.
Summary Melanomas are among the most frequent neoplasms in grey horses. Deep perirectal melanomas, however, are uncommon and challenging to excise due to their proximity to the peritoneal reflection. This report describes the successful standing removal of a large (16 × 8 × 6 cm) perirectal melanoma firmly adherent to the dorsal rectal wall in a 19 ...

Measuring ligand efficacy at the mu-opioid receptor using a conformational biosensor. [PDF]

open access: yes, 2018
The intrinsic efficacy of orthosteric ligands acting at G-protein-coupled receptors (GPCRs) reflects their ability to stabilize active receptor states (R*) and is a major determinant of their physiological effects.
