To test the hypothesis that cerebral capillaries, which share the embroyologic and morphologic characteristics of retinal capillaries, might have the same abnormal permeability in diabetic patients, we investigated the growth hormone response to a small amount of peripherally administered dopamine (1.5 microgram/kg.min). Consistent with the known exclusion of systemic dopamine from brain parenc...

conclusions adherence to the meddiet, according to mds and sofi-mds, may not predict mets components and mets incidence after 3 years of follow-up in iranian adult populations. results after adjusting for potential confounders, neither higher mds nor higher sofi-mds were significantly associated with the mean values of mets components and the risk of metabolic abnormalities incidence after 3 ye...

previous studies had reported that extracellular levels of ascorbic acid have modulatory effects on dopamine receptors. both ascorbic acid and dopamine receptor have an important role in learning and memory processes. however, the central interaction between ascorbic acid and dopamine d2 receptor on spatial learning and memory has not yet been elucidated. all experiments were carried out on mal...

morphine was used as a remedy for the control of diarrhea centuries before it's sedative-analgesic effect was discovered. although several mechanisms have been proposed for the morphine-induced inhibition of gastrointestinal transit (oit), the exact mechanism has not yet been identified. on this basis the possible involvement of the dopaminergic system in morphine-induced inhibition of tra...

the dopamine has been studied theoretically at the b3lyp/6-31g* level were performed in gasphase. we calculated physical parameters like atomic charges, energy (=>), asymmetry parameter(?), chemical shift @iso, dipole moment and isotropic nmr determinant and in this work we usedgaussian 03 at nmr and calculation by using b3lyp methods with 6-31g* basis set.

Abstract Controlled and targeted drug delivery systems consist of a carrier matrix one or more active ingredients. One the roles is to regulate release drug. Uptake, release, differential scanning microcalorimetry (DSC) powder X-ray diffraction (XRD) techniques were used reveal interactions governing dopamine indole from thermoresponsive model polymer gel. The can be completely recovered loaded...

The complex etiology of schizophrenia has prompted researchers to develop clozapine-related multitarget strategies to combat its symptoms. Here we describe a series of new 6-aminomethylbenzofuranones in an effort to find new chemical structures with balanced affinities for 5-HT2 and dopamine receptors. Through biological and computational studies of 5-HT2A and D2 receptors, we identified the re...

Among 27 preclinical carriers of the Huntington disease mutation (PMC), the authors found normal striatal values for MRI volumetry in 88% and for fluorodesoxyglucose PET metabolic index in 67%. Raclopride PET binding potential (RAC-BP) was decreased in 50% and correlated with increases in the product of age and CAG repeat length (p < 0.0005). Dopamine D2 receptor availability measured by RAC-BP...

Recently, adaptively timed, anticipatory changes in hemodynamic responses, independent of neural activity, were described in primate primary visual cortex. Task-related properties of these responses point to a possible link between regional cerebral microcirculation and dopaminergic signaling. In this report, this link is elaborated on the basis of known physiological data and further experimen...
