The metabotropic glutamate 2/3 receptor agonist LY379268 counteracted ketamine-and apomorphine-induced performance deficits in the object recognition task, but not object location task, in rats.

Only registered users can translate articles

Experimental evidence indicates that the non competitive N-methyl-d-aspartate (NMDA) receptor antagonist ketamine and the mixed dopamine (DA) D1/D2 receptor agonist apomorphine induce schizophrenia-like symptoms in rodents, including cognitive deficits. Activation of Group II metabotropic glutamate

Electrophysiologic and hemodynamic effects of apomorphine in dogs.

Only registered users can translate articles

Apomorphine is a dopamine receptor agonist used as an emetic, for Parkinson's disease, and for treating erectile dysfunction. This study was conducted to monitor cardiovascular function in dogs given the standard emetic dose (0.05 mg/kg) or 10 times that. Measurements were made during baseline and

A single report of hemiplegic arm stretching related to yawning: further investigation using apomorphine administration.

Only registered users can translate articles

We observed a stroke patient with an infarct of the internal capsule interrupting the pyramidal tract who stretched his hemiplegic arm during spontaneous and apomorphine-induced yawning. The putative mechanism by which yawning can induce the paradoxical motor response of the plegic arm in the

Systematic and detailed analysis of behavioural tests in the rat middle cerebral artery occlusion model of stroke: Tests for long-term assessment.

Only registered users can translate articles

In order to test therapeutics, functional assessments are required. In pre-clinical stroke research, there is little consensus regarding the most appropriate behavioural tasks to assess deficits, especially when testing over extended times in milder models with short occlusion times and small lesion

"Apraxia of eyelid opening" induced by levodopa therapy and apomorphine in atypical parkinsonism (possible progressive supranuclear palsy): a case report.

Only registered users can translate articles

We report a female patient in whom so-called apraxia of eyelid opening (AEO) developed after the onset of possible progressive supranuclear palsy (National Institute of Neurological Disorders and Stroke criteria) and the introduction of antiparkinsonian medications including levodopa. Although

Chronic metformin treatment improves post-stroke angiogenesis and recovery after experimental stroke.

Only registered users can translate articles

Metformin is currently the first-line treatment drug for type 2 diabetes. Metformin is a well-known activator of AMP-activated protein kinase (AMPK). In experimental studies, metformin has been shown to exert direct vascular effects by increasing vascular endothelial growth factor expression and

Apomorphine rescues reactive oxygen species-induced apoptosis of fibroblasts with mitochondrial disease.

Only registered users can translate articles

Mitochondrial disease is a genetic disorder in which individuals suffer from energy insufficiency. The various clinical phenotypes of mitochondrial disease include Leigh syndrome (LS), myopathy encephalopathy lactic acidosis and stroke-like episodes (MELAS). Thus far, no curative treatment is

Intracerebral transplantation of HLA-homozygous human iPSC-derived neural precursors ameliorates the behavioural and pathological deficits in a rodent model of ischaemic stroke

Only registered users can translate articles

Objectives: Human-induced pluripotent stem cells (hiPSCs) are a promising cell source for treating ischaemic stroke. Although autologous hiPSCs provide the advantage of avoiding immune rejection, their practical limitations, such as

Intra-arterial Administration of Human Umbilical Cord Blood Derived Cells Inversed Learning Asymmetry Resulting From Focal Brain Injury in Rat.

Only registered users can translate articles

Background: Focal brain injury is a leading cause of serious disability significantly worsening patients' quality of life. Such damage disrupts the existing circuits, leads to motor, and cognitive impairments as well as results in a functional asymmetry. To date, there is still no therapy to

Siagoside selectively attenuates morphological and functional striatal impairments induced by transient forebrain ischemia in rats.

Only registered users can translate articles

OBJECTIVE Transient forebrain ischemia induced in rats by the four-vessel occlusion method is known to produce severe neural damage in the hippocampus and striatum and a behavioral syndrome the major symptom of which is a working memory deficit. Recent evidence suggests that monosialogangliosides

Erythropoietin protects dopaminergic neurons and improves neurobehavioral outcomes in juvenile rats after neonatal hypoxia-ischemia.

Only registered users can translate articles

Brain injury as a result of hypoxia-ischemia remains a common cause of morbidity and mortality in neonates. No effective therapy is currently available. The hematopoietic cytokine erythropoietin (Epo) provides neuroprotection in many adult models of brain injury and is currently being investigated

Dl-3-n-butylphthalide, a natural antioxidant, protects dopamine neurons in rotenone models for Parkinson's disease.

Only registered users can translate articles

In the absence of a cure for Parkinson's disease, development of preventive medications for this devastating disease is particularly encouraged. Dl-3-n-butylphthalide (NBP), an established natural antioxidant for clinical stroke treatment in China, can reportedly reduce beta-amyloid-induced neuronal

Stereochemistry in clinical medicine: a neurological perspective.

Only registered users can translate articles

Stereoisomers are compounds that have identical sets of atoms configured in the same positions but are arranged differently spatially. Approximately 25% of contemporary drugs are marketed and used as racemates (i.e., as equimolar mixtures of stereoisomers). This may have major clinical implications,

[Effect of selective activation and blockade of the central dopaminergic system on the course of the early post-traumatic period].

Only registered users can translate articles

Acute experiments on white rats traumatized according to Kenon demonstrated that the central administration of the dopamine receptor agonist apomorphine led a reduction in mortality rates and an increase in stroke and heart indices. The latter was due to the significant activation of the

Free radical scavengers: chemical concepts and clinical relevance.

Only registered users can translate articles

Free radicals are involved in the pathology of many CNS disorders, like Parkinson's disease, Alzheimer's disease, or stroke. This discovery lead to the development of many radical scavengers for the clinical treatment of neurodegenerative diseases. In this review, the different chemical concepts for
