DAILY VARIATION IN PLASMA-CONCENTRATION OF FENCAMFAMINE AND STRIATAL DOPAMINE-RECEPTORS IN RATS
(Associação Brasileira de Divulgação Científica (ABRADIC), 1994-03-01)
Fencamfamine (FCF) is a psychostimulant drug classified as an indirect dopamine agonist. In the present study we evaluated the daily variation in plasma FCF concentration and in striatal dopamine receptors. Adult male ...
A Cerium Hexacyanoferrate (III) Nanoparticle-modified Carbon Paste Electrode: Voltammetric Characterization and Behavior in the Presence of Dopamine
(2020-07-01)
This study describes a fast and simple methodology for the preparation of Cerium (III) Hexacyanoferrate (II) (CeHCF) nanoparticles (NPs). The NPs were characterized by fourier transform infrared (FTIR), x-ray diffraction ...
Interactions of iron, dopamine and neuromelanin pathways in brain aging and Parkinson’s disease
(Elsevier, 2017-08)
There are several interrelated mechanisms involving iron, dopamine, and neuromelanin in neurons.
Neuromelanin accumulates during aging and is the catecholamine-derived pigment of the dopamine
neurons of the substantia ...
Hemiparkinsonian rats rotate toward the side with the weaker dopaminergic neurotransmission
(ELSEVIER SCIENCE BV, 2008)
Rats with unilateral lesion of the substantia nigra pars compacta (SNpc) have been used as a model of Parkinson`s disease. Depending on the lesion protocol and on the drug challenge, these rats rotate in opposite directions. ...
Copper neurotoxicity is dependent on dopamine-mediated copper uptake and one-electron reduction of aminochrome in a rat substantia nigra neuronal cell line
(BLACKWELL SCIENCE LTD, 2001-04)
The mechanism of copper (Cu) neurotoxicity was studied in the RCSN-3 neuronal dopaminergic cell line, derived from substantia nigra of an adult rat. The formation of a Cu-dopamine complex was accompanied by oxidation of ...
Simultaneous voltammetric detection of ascorbic acid, dopamine and uric acid using a pyrolytic graphite electrode modified into dopamine solution
(ELSEVIER SCIENCE BV, 2008)
Pyrolytic graphite electrodes (PGE) were modified into dopamine solutions using phosphate buffer solutions, pH 10 and 6.5, as supporting electrolyte. The modification process involved a previous anodization of the working ...
Síndrome das pernas inquietas: Diagnóstico e tratamento. Opinião de especialistas Brasileiros
(2007-09-01)
This article contains the conclusions of the November 17-18, 2006 meeting of the Brazilian Study Group of Restless Legs Syndrome (GBE-SPI) about diagnosis and management of restless legs syndrome (RLS). RLS is characterized ...
Electrochemical Properties of Oxo-Manganese Complex Biomimicking Enzyme Active Sites and Its Electrocatalytic Application for Dopamine Determination
(2013-05-08)
This work describes the characterization of the [Mn2 IV,IVO2(terpy)2(H2O)2]4+ complex in aqueous solution by UV-vis spectrophotometry, cyclic voltammetry, and linear sweep voltammetry with a rotating disk electrode. The ...
Activation of D1/5 Dopamine Receptors in the Dorsal Medial Prefrontal Cortex Promotes Incubated-Like Aversive Responses
(Frontiers Media S.A., 2017-10)
It is well established that neurons of the mammalian medial prefrontal cortex (mPFC) modulate different behavioral outputs, including several memory types. This behavioral modulation is, at least in part, under the control ...
