Noncovalent Interactions between Dopamine and Regular and Defective Graphene
(Wiley VCH Verlag, 2017-08)
The role of noncovalent interactions in the adsorption of biological molecules on graphene is a subject of fundamental interest regarding the use of graphene as a material for sensing and drug delivery. The adsorption of ...
Dopamine modifies oxygen consumption and mitochondrial membrane potential in striatal mitochondria
(Springer, 2010-04)
Dopamine is a neurotransmitter that has been related to mitochondrial dysfunction. In this study, striatal intact mitochondria and submitochondrial membranes were incubated with different dopamine concentrations, and changes ...
Regulation of Dopamine Uptake by Vasoactive Peptides in the Kidney
(Hindawi Publishing Corporation, 2016-08)
Considering the key role of renal dopamine in tubular sodium handling, we hypothesized that c-type natriuretic peptide (CNP) and Ang-(1-7) may regulate renal dopamine availability in tubular cells, contributing to Na+, ...
Dipole moment effects in dopamine/N-doped-graphene systems
(Elsevier Science, 2019-11)
In the present work the effect exerted by N-doping on parameterscharacterizing dopamine adsorption on modified graphene substrate is theoretically studied.Moreover, an analysis of dipole moment properties of dopamine/N-d ...
Inhibitors of 20-hydroxyeicosatetraenoic acid (20-HETE) formation attenuate the natriuretic effect of dopamine
(Elsevier Science, 2012-07)
Endogenous renal dopamine is a major physiological regulator of renal ion transport; however its intracellular signaling pathways are not thoroughly understood. The present study examined the role of 20-hydroxyeicosatetraenoic ...
Selective increase of Nurr1 mRNA expression in mesencephalic dopaminergic neurons of D2 dopamine receptor-deficient mice
(Elsevier, 2000-07)
The orphan nuclear receptor Nurr1 is critical for the survival of mesencephalic dopaminergic precursor neurons. Little is known about the mechanisms that regulate Nurr1 expression in vivo. Other members of this receptor ...
Dopamine in the dorsal hippocampus impairs the late-consolidation of cocaine-associated memory
(Nature Publishing Group, 2014-01)
Cocaine is thought to be addictive because it elevates dopamine levels in the striatum, reinforcing drug-seeking habits. Cocaine also elevates dopamine levels in the hippocampus, a structure involved in contextual conditioning ...
Two-Photon Optical Interrogation of Individual Dendritic Spines with Caged Dopamine
(American Chemical Society, 2013-05)
We introduce a novel caged dopamine compound (RuBi-Dopa) based on ruthenium photochemistry. RuBi-Dopa has a high uncaging efficiency and can be released with visible (blue-green) and IR light in a two-photon regime. We ...
Neutral and zwitterionic dopamine species adsorbed on silver surfaces: A DFT investigation of interaction mechanism
(John Wiley & Sons Inc, 2018-09-27)
Biomolecules nondissociative adsorption on noble metals is a key process in metallic biosensors implying several questions related to the stability and orientation of such molecules. Here, the neurotransmitter dopamine ...
Highly selective determination of dopamine in the presence of ascorbic acid and serotonin at glassy carbon electrodes modified with carbon nanotubes dispersed in polyethylenimine
(American Scientific Publishers, 2008-11)
We report the highly selective and sensitive voltammetric dopamine quantification in the presence of ascorbic acid and serotonin by using glassy carbon electrodes modified with a dispersion of multiwall carbon nanotubes ...
