In Vivo Regulation of the μ Opioid Receptor: Role of the Endogenous Opioid Agents

open access: yesMolecular Medicine, 2013
It is well known that genotypic differences can account for the subject-specific responses to opiate administration. In this regard, the basal activity of the endogenous system (either at the receptor or ligand level) can modulate the effects of ...

The Effect of Exogenously Applied Dicarboxylic Acids (Photon) on the Maize (Zea mays) Metabolite Profile

open access: yesChemistry &Biodiversity, Volume 22, Issue 11, November 2025.
ABSTRACT Maize is an important crop worldwide with approximately 1200 million tons consumed and a market size worth $143 billion. Environmental stress influence production of crops and mitigating these ensures optimum production. Dicarboxylic acids are known as emulsifying agents that mitigate various stresses in plants.

Nitrous Oxide: Mechanism of Its Antinociceptive Action [PDF]

open access: yes, 1995
Nitrous oxide (N2O) is an anesthetic gas known to produce an analgesic effect at sub-anesthetic concentrations. This analgesic property of N2O can be clinically exploited in a broad range of conditions where pain relief is indicated.

μ‐Opioid Receptor Dynamics in the Parameningeal Tissue During Migraine Attacks

open access: yesAnnals of Neurology, Volume 98, Issue 4, Page 777-787, October 2025.
Objective The possible impact of meningeal μ‐opioid receptor (μOR) binding in migraine remains unknown. This study investigated μOR availability in the cranial parameninges involved in migraine initiation via nociceptor activation. Methods We used positron emission tomography with [11C] carfentanil, and measured μOR availability in meninges and ...

Simulated Annealing with Tsallis Weights - A Numerical Comparison

open access: yes, 1997
We discuss the use of Tsallis generalized mechanics in simulated annealing algorithms. For a small peptide it is shown that older implementations are not more effective than regular simulated annealing in finding ground state configurations. We propose a

Generalized-ensemble simulations of spin systems and protein systems

open access: yes, 2001
In complex systems such as spin systems and protein systems, conventional simulations in the canonical ensemble will get trapped in states of energy local minima.

Met-enkephalins in patients with inflammatory bowel diseases

open access: yesAdvances in Medical Sciences, 2011
Opioid peptides provide a link between the neuroendocrine and immune systems. They modify the inflammatory process through their effect on the synthesis and secretion of cytokines and on the proliferation of leukocytes to the inflammatory lesion. The evaluation analyzed changes in free met-enkephalin concentration values in the serum and colon mucosal ...

Activation of µ-opioid receptors inhibits calcium-currents in the vestibular afferent neurons of the rat through a cAMP dependent mechanism

open access: yesFrontiers in Cellular Neuroscience, 2014
Opioid receptors are expressed in the vestibular endorgans (afferent neurons and hair cells) and are activated by the efferent system, which modulates the discharge of action potentials in the vestibular afferent neurons (VANs).
