Cocaine and amphetamine‑regulated transcript (CART) is a neuropeptide that can protect brains against ischemic injury. The aim of the present study was to investigate the effects of the CART within ischemic stroke and it possible mechanism. The expression levels of dopamine (DA) and CART in ischemic
Serum dopamine-beta-hydroxylase (DBH) activity was measured in 34 patients with acute cerebrovascular disease. The serum level of DBH activity showed its highest value soon after the onset of stroke and then gradually decreased over the next few days. After reaching its lowest level, the DBH
BACKGROUND
Stroke has a huge impact, leaving more than a third of affected people with lasting disability and rehabilitation remains a cornerstone treatment in the National Health Service (NHS). Recovery of mobility and arm function post-stroke occurs through re-learning to use the affected body
The effect of focal photothrombotic stroke on the distribution of D1 dopamine receptor (D1R) sites was examined in different cortical areas of rat brain with quantitative receptor autoradiography using [3H]SCH23390 as a ligand. Unilateral cortical stroke was located in the primary somatosensory
1. The relaxant effects of dopamine (DA) on the intrarenal arteries obtained from 6 month old stroke-prone spontaneously hypertensive rats (SHRSP) and age-matched Wistar-Kyoto (WKY) rats were pharmacologically investigated in vitro. 2. DA (10(-7)-3 x 10(-5) mol/L) produced endothelium-independent
Hemispatial neglect following right-hemisphere stroke is a common and disabling disorder, for which there is currently no effective pharmacological treatment. Dopamine agonists have been shown to play a role in selective attention and working memory, two core cognitive components of neglect. Here,
Dopamine-beta-hydroxylase (DBH) activity was higher in the serum, the mesenteric artery and the cerebral cortex of 4-week-old stroke-prone spontaneously hypertensive rats (SHRSP), and lower in the nucleus tractus solitarii than it was in spontaneously hypertensive rats (SHR).
Cerebral dopamine neurotrophic factor plays a critical role in repairing and maintaining healthy neurons in pathological conditions such as stroke. However, the association between cerebral dopamine neurotrophic factor expression and stroke has only recently been investigated in Many researches that discourse the treatment of prolactinomas with dopamine agonists (DA) provide data about pituitary tumor apoplexy of some prolactinomas. Therefore, DA are listed as risk factors for apoplexy of prolactinomas. The authors wish to explore the percentage (frequency) of pituitary
Dopamine is a key modulator of striatal function and learning, and may improve motor recovery after stroke. Seven small trials of dopamine agonists after stroke have provided equivocal evidence of the clinical effectiveness of dopamine agonists in improving motor Data on the relationship between idiopathic Parkinson's disease (IPD) and stroke are conflicting. In this study, we examined the frequency of IPD in stroke patients registered in the Maastricht Stroke Registry. With the use of three different search strategies, we found eight individuals with IPD
Functional recovery after a stroke is important for patients' quality of life. Not only medical care during the acute phase, but also rehabilitation during the chronic phase after a stroke is important. However, the mechanisms underlying functional recovery, particularly the chronic phase after
The dopamine-releasing and depleting substance amphetamine (AMPH) can make cortical neurons susceptible to damage, and the prevention of hyperthermia, seizures and stroke is thought to block these effects. Here we report a 2-day AMPH treatment paradigm which affected only interneurons in three
Dopamine release into the extracellular space was measured with in vivo electrochemical detection in the ipsilateral and contralateral striata in Mongolian gerbils that suffered a stroke after acute unilateral carotid artery ligations. A sevenfold increase in the dopamine signal occurred within 15
Astrocyte-mediated neuroinflammation plays a critical role in ischemic stroke-induced secondary cerebral injury. Previous studies have suggested that the dopamine D2 receptor (DRD2) acts as a key target in regulating the neuroinflammatory response. However, the underlying molecular mechanisms are
