TRYptophan-COntaining Non-Cationizable Opioid PeptideS (TRYCONCOPS): A new paradigm for opioid peptides

open access: yes, 2014
Despite of the current availability of new synthetic drugs, morphine and the other alkaloids found in the opium poppy plant still represent the drugs of choice for the relief of serious pain caused by cancer or other maladies. However, long-term usage is

Effects of chronic treatment with atypical neuroleptics on the biosynthesis and release of opioid peptides in guinea-pig ileum

open access: yes, 1985
The guinea-pig ileum myenteric plexus is known to contain opioid peptides, which can be released by electric stimulation at high frequency. Haloperidol, a classic neuroleptic drug, increases the biosynthesis and release of endogenous opioid peptides from

Pre‐anaesthetic risk assessment and management of dogs with myxomatous mitral valve disease: a spectrum of care narrative review

open access: yesJournal of Small Animal Practice, EarlyView.
Myxomatous mitral valve disease, an acquired valvular degeneration, is the most common cardiac disorder in dogs, affecting approximately 10% of dogs in primary care veterinary practice. Dogs with myxomatous mitral valve disease frequently require anaesthesia for routine procedures.

Morphine and opioid peptides selectively inhibit the non-cholinergically mediated neurogenic contraction of guinea-pig isolated bronchial muscle

open access: yes, 1990
The experiments examine the actions of morphine and opioid peptides on the responses evoked by electrical field stimulation or by acetylcholine (ACh) and substance P (SP) in guinea-pig bronchial strip chain. Electrical field stimulation evoked a biphasic

Use of liquid platelet‐rich fibrin (liquid PRF) in temporomandibular joint disorders: A narrative review with clinical recommendations

open access: yesPeriodontology 2000, EarlyView.
Abstract Aim This narrative review aimed to gather evidence from comparative and non‐comparative clinical studies to assess: (1) whether the administration of liquid platelet‐rich fibrin (liquid PRF) provides any clinical benefits for managing temporomandibular disorders (TMD), and if so, based on comparative clinical studies, (2) whether it offers ...

Antagonism in opioid peptides: The role of conformation

open access: yes, 2004
The availability of new, highly selective antagonists, in the field of opioid peptides and of other pain peptides, is important both for a better understanding of the interaction of the receptors with their ligands and for their practical relevance.

Therapeutic potential of spexin in diabetic neuropathy: Insights from in vitro and in vivo models

open access: yesExperimental Physiology, EarlyView.
Abstract The present study investigated the therapeutic potential of spexin (SPX) on both in vitro and in vivo models of diabetic neuropathy (DN). A total of 40 male BALB/c mice were randomly allocated into four experimental groups (n = 10 per group): a normoglycaemic control, an untreated DN group and two SPX treatment groups (DN+SPX‐12.5 and DN+SPX ...
