Frontiers in Molecular Neuroscience, 2018 The adaptation to chronic stress is highly variable across individuals. Resilience to stress is a complex process recruiting various brain regions and neurotransmitter systems. The aim of this study was to investigate the involvement of endogenous opioid

eLife, 2021 Functional interactions between G protein-coupled receptors are poised to enhance neuronal sensitivity to neuromodulators and therapeutic drugs. Mu and delta opioid receptors (MORs and DORs) can interact when overexpressed in the same cells, but whether ...

Journal of Biological Chemistry, 1983 Enkephalin convertase, an enkephalin-synthesizing carboxypeptidase present in adrenal medulla chromaffin granules, has also been detected in brain and pituitary. To determine whether these three carboxypeptidase activities represent the same enzyme, we purified and characterized enkephalin convertase from adrenal medulla, whole brain, and whole ...

Neurobiology of Disease, 2001 Opioid receptor-binding autoradiography was used as a way to map sites of altered opioid transmission in a rat model of l-DOPA-induced dyskinesia. Rats with unilateral 6-hydroxydopamine lesions of the nigrostriatal pathways sustained a 3-week treatment ...

Effective Sampling in the Configurational Space by the Multicanonical-Multioverlap Algorithm
, 2006 We propose a new generalized-ensemble algorithm, which we refer to as the multicanonical-multioverlap algorithm. By utilizing a non-Boltzmann weight factor, this method realizes a random walk in the multi-dimensional, energy-overlap space and explores ...

The organisation of spinoparabrachial neurons in the mouse [PDF]
, 2015 The anterolateral tract (ALT), which originates from neurons in lamina I and the deep dorsal horn, represents a major ascending output through which nociceptive information is transmitted to brain areas involved in pain perception.

RELEASE OF VASOPRESSIN BY ENKEPHALIN [PDF]
British Journal of Pharmacology, 1978 Leu‐enkephalin, its stable analogue [D‐Ala2‐D‐Leu5]‐enkephalin and the C‐fragment of lipotropin (β endorphin) injected intravenously in the rat produced anti‐diuretic responses which were inhibited reversibly by naloxone. It was shown for Leu‐enkephalin that injection into the cerebral ventricles was at least ten times more effective than intravenous ...

Striatal Neuropeptides Enhance Selection and Rejection of Sequential Actions
Frontiers in Computational Neuroscience, 2017 The striatum is the primary input nucleus for the basal ganglia, and receives glutamatergic afferents from the cortex. Under the hypothesis that basal ganglia perform action selection, these cortical afferents encode potential “action requests.” Previous

Frontiers in Medicine, 2021 Background: Chronic pruritus affects up to 70% of patients with immune-mediated hepatobiliary disorders. Antagonists of the μ-opioid receptor (MOR) and agonists of the κ-opioid receptor (KOR) are used to treat hepatic itch, albeit with limited success ...

Chemistry &Biodiversity, EarlyView.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.
