In monkeys rendered parkinsonian with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), expression of the dopamine D3 receptor was decreased. However, levodopa-induced dyskinesia (LID), similar to… (More)
The role of the D(3) receptor has remained largely elusive before the development of selective research tools, such as selective radioligands, antibodies, various highly specific pharmacological… (More)
Benefit and motor side effects of l-DOPA in Parkinson's disease have been related to dopamine transmission in the striatum. However, the putative involvement of serotonergic neurons in the… (More)
The therapeutic benefit of L-DOPA is commonly attributed to restoration of dopamine (DA) extracellular levels in the striatum of Parkinsonian patients. However, the loss of efficacy of L-DOPA after… (More)
In animal models of Parkinson's disease (PD), it is postulated that the excessive output from the subthalamic nucleus (STN) plays a critical role. Selective lesions or high frequency electrical… (More)
In Parkinson's disease, experimental studies favour a neuronal hyperactivity of the subthalamic nucleus. We carried out a subthalamic nucleus electrical stimulation in a patient aged 51, suffering… (More)
Progression of superior adjacent segment degeneration (PASD) could possibly be avoided by dynamic stabilization of an initially degenerated adjacent segment (AS). The current study evaluates ex vivo… (More)
A retrospective clinical–radiological study to evaluate the long-term outcome after artificial disc replacement was performed. The objective is to investigate long-term results after implantation of… (More)
PURPOSE
To study bystander demyelination in multiple sclerosis with an experimental in vivo model of toxic demyelination.
METHODS
Toxic demyelinating lesions were created in two monkeys by… (More)
Brain-derived neurotrophic factor (BDNF) belongs to a family of proteins related to nerve growth factor, which are responsible for neuron proliferation, survival and differentiation. A more diverse… (More)
