Metropolis simulations of Met-Enkephalin with solvent-accessible area parameterizations [PDF]

open access: yes, 2003
We investigate the solvent-accessible area method by means of Metropolis simulations of the brain peptide Met-Enkephalin at 300$ K$. For the energy function ECEPP/2 nine atomic solvation parameter (ASP) sets are studied. The simulations are compared with

Effects of Long-term antipsychotic treatment on enkephalin-immunoreactive neurons in rats perinatally treated with phencyclidine [PDF]

open access: yesMedicinski Podmladak, 2023
Introduction: Schizophrenia is a chronic mental illness that affects 1% of the world's population. The phencyclidine animal model of schizophrenia is based on the glutamate theory of the development of schizophrenia.

Characteristic Temperatures of Folding of a Small Peptide [PDF]

open access: yes, 1997
We perform a generalized-ensemble simulation of a small peptide taking the interactions among all atoms into account. From this simulation we obtain thermodynamic quantities over a wide range of temperatures.

Enkephalin as a Pivotal Player in Neuroadaptations Related to Psychostimulant Addiction

open access: yesFrontiers in Psychiatry, 2018
Enkephalin expression is high in mesocorticolimbic areas associated with psychostimulant-induced behavioral and neurobiological effects, and may also modulate local neurotransmission in this circuit network.

Exposure to exogenous enkephalins disrupts reproductive development in the Eastern lubber grasshopper, Romalea microptera (Insecta: Orthoptera). [PDF]

open access: yesPLoS ONE, 2012
Enkephalins play a major role in reproductive physiology in crustaceans; however their role in reproductive development in insects is largely unknown. We investigated the effect of exposure to exogenous leucine-enkephalin (Leu-Enk), methionine-enkephalin

Effect of met-enkephalin on chromosomal aberrations in the lymphocytes of the peripheral blood of patients with multiple sclerosis

open access: yesBiomolecules & Biomedicine, 2014
Endogenious opiod met-enkephalin throughout previous research manifested cytoprotective and anti-inflammatory effects. Previous research suggests that met-enkephalin has cytogenetic effects.

Cocaine Reduces the Neuronal Population While Upregulating Dopamine D2-Receptor-Expressing Neurons in Brain Reward Regions: Sex-Effects

open access: yesFrontiers in Pharmacology, 2021
Addiction to cocaine is associated with dysfunction of the dopamine mesocortical system including impaired dopamine-2 receptor (D2r) signaling. However, the effects of chronic cocaine on neuronal adaptations in this system have not been systematically ...

Distinct forms of synaptic inhibition and neuromodulation regulate calretinin positive neuron excitability in the spinal cord dorsal horn [PDF]

open access: yes, 2016
The dorsal horn (DH) of the spinal cord contains a heterogenous population of neurons that process incoming sensory signals before information ascends to the brain.

Synthetic Analogue of Leu-Enkephalin Prevents Endothelial Dysfunction in vitro

open access: yesОбщая реаниматология, 2018
The purpose of the study was to determine the efficacy of a synthetic leu-enkephalin stabilized analogue to prevent damage of endothelial cells monolayer in vitro caused by serum samples from septic shock patients.Materials and methods.
