Novel therapeutic targets for chronic visceral pain in gastrointestinal disorders

British Journal of Pharmacology, EarlyView.
Chronic visceral pain imposes a major clinical challenge in gastroenterology and beyond, profoundly impacting patients' quality of life. However, limited understanding of its complex, multifaceted pathophysiology, encompassing both peripheral and central mechanisms, continues to impede the development of effective management strategies.

Molecular Perspectives for mu/delta Opioid Receptor Heteromers as Distinct, Functional Receptors

Cells, 2014
Opioid receptors are the sites of action for morphine and the other opioid drugs. Abundant evidence now demonstrates that different opioid receptor types can physically associate to form heteromers.

Detection of confinement and jumps in single molecule membrane trajectories

, 2006
We propose a novel variant of the algorithm by Simson et al. [R. Simson, E.D. Sheets, K. Jacobson, Biophys. J. 69, 989 (1995)]. Their algorithm was developed to detect transient confinement zones in experimental single particle tracking trajectories of ...

Cancer pain: current practice and emerging targets

British 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‐

Secondary metabolites isolated from Pinus roxburghii and interpretation of their cannabinoid and opioid binding properties by virtual screening and in vitro studies

Saudi Pharmaceutical Journal, 2018
Pinus roxburghii is highly popular as a potent analgesic and anti-inflammatory agent; however its exact mechanism of action was not fully elucidated. We aimed to interpret the analgesic and anti-inflammatory activity of the total ethanol extract of Pinus

Divergent modulation of nociception by glutamatergic and GABAergic neuronal subpopulations in the periaqueductal gray [PDF]

, 2017
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

Novel Histopathologic Features of Diffuse Blue‐Gray Hyperpigmentation Associated With Kratom Use: A Case Report and Literature Review

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Background Drug‐induced hyperpigmentation accounts for 10%–20% of acquired pigmentary disorders and can be misdiagnosed for other causes such as melasma, post inflammatory changes, or heavy metal deposition. Kratom (Mitragyna speciosa), a Southeast Asian plant with an opioid‐like profile, has been increasingly used in the United States for ...

Physiological and behavioural effects of continuous remifentanil‐xylazine administration in donkeys

Equine Veterinary Journal, EarlyView.
Abstract Background Remifentanil and xylazine are used as continuous infusions to facilitate standing surgery in horses. Their use for this purpose has not been reported in donkeys. Objectives To evaluate the behavioural, sedative, and cardiorespiratory effects of continuous intravenous infusion of remifentanil and xylazine in donkeys. Study Design Non‐

Involvement of Peripheral Beta-Endorphin and MU, Delta, Kappa Opioid Receptors in Electro Acupuncture Analgesia for Prolonged Inflammatory Pain of Rats

European Journal of Inflammation, 2013
Acupuncture is commonly used to relieve chronic pain worldwide. Accumulating evidence shows that peripheral opioid system plays an important role in inhibiting inflammatory pain. This study aimed to investigate the involvement of peripheral opioid system

Effect of intrauterine morphine sulfate exposure on cerebellar histomorphological changes in neonatal mice [PDF]

, 2011
Neurotoxic effects of morphine sulfate in adult cerebellar cortex and neonatal cerebral cortex have been studied in animal models. This study was done to determine the neurotoxic effects of prenatal morphine exposure on the histo morphological changes of
