Chronic exposure to dopamine agonists affects the integrity of striatal D2 receptors in Parkinson's patients

open access: yesNeuroImage: Clinical, 2017
We aimed to investigate the integrity and clinical relevance of striatal dopamine receptor type-2 (D2R) availability in Parkinson's disease (PD) patients. We studied 68 PD patients, spanning from early to advanced disease stages, and 12 healthy controls.

Dopamine modulation via memristive schematic [PDF]

open access: yesarXiv, 2017
In this technical report we present novel results of the dopamine neuromodulation inspired modulation of a polyaniline (PANI) memristive device excitatory learning STDP. Results presented in this work are of two experiments setup computer simulation and physical prototype experiments.

Dopamine agonists and the risk of cardiac-valve regurgitation.

open access: yesNew England Journal of Medicine, 2007
BACKGROUND Case reports and echocardiographic studies suggest that the ergot-derived dopamine agonists pergolide and cabergoline, used in the treatment of Parkinson's disease and the restless legs syndrome, may increase the risk of cardiac-valve ...

The enteric nervous system : new developments and emerging concepts [PDF]

open access: yes, 2011
The enteric nervous system (ENS) is an integrative neuronal network, organized in two ganglionated plexuses, myenteric and submucosal, composed of neurons and enteric glial cells, controlling the activity of the smooth muscle of the gut, mucosal ...

Agonist-Antagonist Pouch Motors: Bidirectional Soft Actuators Enhanced by Thermally Responsive Peltier Elements [PDF]

open access: yes
In this study, we introduce a novel Mylar-based pouch motor design that leverages the reversible actuation capabilities of Peltier junctions to enable agonist-antagonist muscle mimicry in soft robotics. Addressing the limitations of traditional silicone-based materials, such as leakage and phase-change fluid degradation, our pouch motors filled with ...

Dopamine D-3 receptors regulate GABA(A) receptor function through a phospho-dependent endocytosis mechanism in nucleus accumbens [PDF]

open access: yes, 2006
The dopamine D-3 receptor, which is highly enriched in nucleus accumbens (NAc), has been suggested to play an important role in reinforcement and reward.
