Endogenous opioid systems alterations in pain and opioid use disorder

Frontiers in Systems Neuroscience, 2022
Decades of research advances have established a central role for endogenous opioid systems in regulating reward processing, mood, motivation, learning and memory, gastrointestinal function, and pain relief.

Anti‐Inflammatory and Antibacterial Properties of Curcuma longa Extract Against Helicobacter pylori

Molecular Nutrition &Food Research, EarlyView.
This study explored the effects of Curcuma longa extract (CLE) against H. pylori infection. CLE contained 18 chemical compounds and completely inhibited growth of H. pylori Sydney strain 1 (SS1) in vitro. In infected mice with H. pylori SS1, oral administration of CLE successfully eradicated H.

Electroacupuncture attenuates retinal ischemia/reperfusion injury by protecting the outer blood-retina barrier via enkephalins activate delta opioid receptor

World Journal of Acupuncture - Moxibustion
Objectives: Retinal ischemia-reperfusion (RIR) injury results in irreversible visual impairments. The disruption of the outer blood-retinal barrier (OBRB) is a major ocular pathogenic process that RIR injury affects.

Neuropeptide Profiles of Mammalian Male Genital Tract: Distribution and Functional Relevance in Reproduction

Frontiers in Veterinary Science, 2022
Neuropeptides are secretory peptides characterized by small chains of amino acids linked by peptide bonds. They are majorly found in some mammalian neurons and glial cells, where they modulate a variety of physiological homeostasis.

The distribution and functions of the enkephalins. [PDF]

Journal of Histochemistry & Cytochemistry, 1980
The enkephalins are two pentapeptides with pharmacological properties similar to narcotic drugs. These peptides are widely distributed in the central nervous system. The basal ganglia contain particularly high concentrations of enkaphalins. In the caudate nucleus ultrastructural studies show that enkephalin is contained within synaptic vesicles ...

N‐Geranylated Amino Acid Surfactants with Low Critical Micelle Concentrations from Abundant, Naturally Derived Starting Materials

ChemistryOpen, EarlyView.
Cleaning Up Surfactants: Realising critical micelle concentrations lower than sodium dodecyl sulfate with sustainable surfactants prepared from amino acids and naturally occurring aldehydes. In this work, a simple method for the preparation of N‐alkylated amino acid surfactants in 1–2 steps is reported.

Quality Control Strategies for Differentiation of Kalanchoe Species

Phytochemical Analysis, EarlyView.
ABSTRACT Kalanchoe species products are commercially available in local markets and by internationally accessible online retailers and may exhibit quality issues because of misidentification from similar common names and anatomical similarities among related species used as feedstock. This study proposes an approach using UPLC‐MS/MSE and HPTLC, coupled

Asthma induced by enkephalin. [PDF]

BMJ, 1980
A total of 291 diabetics were studied to see whether an asthmatic reaction was associated with facial flushing induced by chlorpropamide and alcohol. Of these patients, 191 reported facial flushing, of whom 12 reported breathlessness as well. Of these 12, five also described wheezing, and respiratory function tests showed them to have asthma.

Electroacupuncture as a treatment for suspected trigeminal nerve‐mediated head‐shaking in 42 horses

Equine Veterinary Education, EarlyView.
Summary Background Electroacupuncture (EA) has been used successfully as a treatment for trigeminal nerve‐mediated head‐shaking (TMHS) in a small case series, but results from a larger number of cases are lacking. Objectives To retrospectively investigate the effectiveness of EA as a treatment for horses with TMHS.

Interactions of the opioid and cannabinoid systems in reward: Insights from knockout studies

Frontiers in Pharmacology, 2015
The opioid system consists of three receptors, mu, delta, and kappa, which are activated by endogenous opioid peptides (enkephalins, endorphins and dynorphins). The endogenous cannabinoid system comprises lipid neuromodulators (endocannabinoids), enzymes
