Endothelium‐derived dopamine modulates EFS‐induced contractions of human umbilical vessels

Pharmacology Research & Perspectives, 2020
Electrical field stimulation (EFS) induces contractions of both snake aorta and human umbilical cord vessels (HUCV) which were dependent on the presence of the endothelium.

A quantum chemical approach representing a new perspective concerning agonist and antagonist drugs in the context of schizophrenia and Parkinson's disease.

PLoS ONE, 2019
Schizophrenia and Parkinson's disease can be controlled with dopamine antagonists and agonists. In order to improve the understanding of the reaction mechanism of these drugs, in this investigation we present a quantum chemical study of 20 antagonists ...

Apo-ghrelin receptor (apo-GHSR1a) Regulates Dopamine Signaling in the Brain

Frontiers in Endocrinology, 2014
The orexigenic peptide hormone ghrelin is synthesized in the stomach and its receptor growth hormone secretagogue receptor (GHSR1a) is expressed mainly in the central nervous system (CNS).

The Pharmacologic Treatment of Stuttering and Its Neuropharmacologic Basis

Frontiers in Neuroscience, 2020
Stuttering is a DSM V psychiatric condition for which there are no FDA-approved medications for treatment. A growing body of evidence suggests that dopamine antagonist medications are effective in reducing the severity of stuttering symptoms.

Effects of dopamine antagonists on receptive fields of brisk cells and directionally selective cells in the rabbit retina

Journal of Neuroscience, 1984
The effects of dopamine antagonists on the extracellularly recorded activity of ON- and OFF-center brisk ganglion cells and ON-OFF directionally selective ganglion cells in the rabbit retina were investigated.

New information of dopaminergic agents based on quantum chemistry calculations

Scientific Reports, 2020
Dopamine is an important neurotransmitter that plays a key role in a wide range of both locomotive and cognitive functions in humans. Disturbances on the dopaminergic system cause, among others, psychosis, Parkinson’s disease and Huntington’s disease ...

Pharmacological Evidence That Dopamine Inhibits the Cardioaccelerator Sympathetic Outflow via D2-Like Receptors in Pithed Rats

Journal of Pharmacological Sciences, 2013
It has been suggested that N,N-di-n-propyl-dopamine (dopamine analogue) decreased heart rate in rats through stimulation of dopamine receptors. Nevertheless, the role of prejunctional dopamine D1/2-like receptors or even α2-adrenoceptors to mediate ...

Hemichorea after hypoglycemic episodes with negative MRI findings in an elderly woman with poorly controlled type 2 diabetes mellitus: a case report

BMC Neurology, 2019
Background Diabetic chorea appears during the course of poorly-controlled diabetes. While chorea associated with diabetes mellitus usually occurs during hyperglycemic episodes, hypoglycemia can also cause diabetic chorea. Brain magnetic resonance imaging
