Objectives: To study the antioxidant capacity of Murraya koeingii essential oil (MKEO) phytoconstituents Methods: It was determined by using GCMS. The were then exposed to molecular docking studies that targeted dopamine D2 look for neuroprotective effects. highest percentage content constituents selected as ligands and dopamine(6VMS) retrieved from protein data bank, performed Schrodinger soft...

The Density Functional Theory (DFT) and the Natural Bond Orbital (NBO) calculations basedmethod B3LYP/6-31G were carried out to study the interaction of Dopamine with carbon nanotube.The nanotube used in this study, includes 60 C atoms (6, 6) type. Relative and formation energies ofcompounds, Muliken charges, occupancy, the highest occupied molecular orbital (HOMO) and thelowest unoccupied mole...

Midbrain dopamine neurons project densely to the striatum and form so-called dopamine synapses on medium spiny neurons (MSNs), principal neurons in the striatum. Because dopamine receptors are widely expressed away from dopamine synapses, it remains unclear how dopamine synapses are involved in dopaminergic transmission. Here we demonstrate that dopamine synapses are contacts formed between dop...

Direct effects of dopamine on renin release were examined using static incubations and perifusions of rat renal cortical slices. Dopamine (10(-5)M) significantly stimulated renin release compared with control. To determine which receptors are involved in dopamine-elicited renin release, studies were performed with specific dopamine-1 and dopamine-2 receptor agonists and antagonists, as well as ...

Dopamine (dihydroxyphenethylamine) is an organic compound from the family of Catecholamines and Phenylamines plays important role in brain functioning. synthesized by precursors kidneys brain. among essential neurotransmitters brain, which especially involved pleasure reward circuits, motivation, motor controls, functional ability, perception, sexual satisfaction, inhibition milk secretion (lac...

For the first time, an MIP potentiometric sensor based covalent recognition for determination of protonated dopamine is described.

Cocaine primarily exerts its behavioral effects by enhancing dopaminergic neurotransmission, amplifying dopamine-encoded sensorimotor integration. The presumed mechanism for this effect is inhibition of the dopamine transporter, which blocks dopamine uptake and prolongs the duration of dopamine in the extracellular space. However, there is growing evidence that cocaine can also augment dopamine...

Administration of apomorphine and amphetamine induces climbing behavior in mice due to stimulation of brain dopamine receptors. In the present study, the effects of adrenoceptor agonists and antagonists on amphetamine-induced climbing have been investigated. Intraperitoneal (i.p.) injection of different doses of amphetamine (2,4 and 8 mglkg) induced climbing in mice (p<O.OOO 1). The u2- ad...

Although dopamine is implicated in the development of addiction, it is unclear how specific dopamine release patterns are involved with drug seeking. Addictive drugs increase tonic dopamine levels on the order of minutes, as well as phasic dopamine release events that occur on a subsecond time scale. Phasic dopamine release is associated with the initiation of goal-directed behaviors, and has b...
