Dopamine concentration abnormalities in the body can cause various disorders and diseases such as Parkinson's, Tourette's syndrome, depression. In this study, graphene oxide (GO) was combined with Fe3O4 to sensitively selectively detect dopamine. The performance evaluated by cyclic voltammetry (CV) differential pulse (DPV) methods. results of testing CV on solution [Fe(CN)6] showed that a modif...
Chemical investigation of the methanol crude extract dried flower buds Syzygium aromaticum (Myrtaceae) resulted in isolation seven known compounds; oleanolic acid (1), lignoceric (2), β-sitosterol (3), heneicosanoic (4), 5-hydroxy-7-methoxy-2-methylchromone (5), 5-hydroxy-7-methoxy-2,8-dimethylchromone (6) and vanillin (7). Their structures were elucidated using one-dimensional NMR spectroscopy...
A brain dopamine receptor that modulates phosphatidylinositol (PI) metabolism via the activation of phospholipase Cbeta (PLCbeta) has been described previously. The present study aims to define the downstream signaling cascade initiated by the PI-linked dopamine receptor. Incubation of rat brain frontal cortical slices with 6-chloro-7,8-dihydroxy-3-methyl-1-(3-methylphenyl)-2,3,4,5-tetrahydro-1...
Psychiatric disorders are one of the most common health problems among different communities including Iran. According to the latest national-width survey, the prevalence of psychiatric disorders among Iranian general population is 23.44% by (1). Therefore, psychotropics, which are prescribed by psychiatrists, other specialists, and general practitioners, are among the most popular and best-sel...
While the work of several groups has shown the neuroprotective effects of nicotine in vitro, evidences for the same effects in vivo are controversial, mainly regarding neuroprotection in experimental models of Parkinson's disease. In this context, we investigated the capability of various systemic administration schedules of nicotine to prevent the loss of striatal dopamine levels produced by p...
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...
introduiction: this study aimed to investigate the protective effects of 12-week voluntary exercise using a running wheel on the striatum dopaminergic neurons against 6-hydroxydopamine lesions in rats. materials and method: twenty five rats were divided into three groups including healthy, parkinson and training-parkinson. the training groups were housed in individual cages geared with running...
Pituitary adenylate cyclase-activating polypeptide (PACAP) rescues dopaminergic neurons from neurodegeneration and improves motor changes induced by 6-hydroxy-dopamine (6-OHDA) in rat parkinsonian models. Recently, we investigated the molecular background of the neuroprotective effect of PACAP in dopamine (DA)-based neurodegeneration using rotenone-induced snail and 6-OHDA-induced rat models of...
Quinoline based new Schiff bases were synthesized from 3-Actyl 4-Hydroxy Quinolin-2-(1H)-one and screened their antibacterial antifungal activity. The 4-hydroxy-3-(1-((4-picolin-2-yl)imino)ethyl)quinolin-2-(1H)-one(L1),4-hydroxy-3-(1-((5-picolin-2-yl)imino)ethyl)quinolin-2(1H)-one(L2),4-hydroxy-3-(1-((6-picolin-2-yl)-imino)ethyl)quinolin-2(1H)-one(L3) 4-hydroxy-3-(1-((3-nitro-4-picolin-2-yl)imi...
