Only a few studies mention the existence of tyrosine hydroxylase immunoreactive neurons in the striatum. These neurons are known to be increased following lesion of the dopaminergic nigrostriatal pathway. Recently it has been shown that glial cell line-derived neurotrophic factor treatment was able to increase the number of these neurons in the(More)
PURPOSE Lipid nanocapsules (LNC) entrapping lipophilic complexes of (188)Re ((188)Re(S(3)CPh)(2)(S(2)CPh) [(188)Re-SSS]) were investigated as a novel radiopharmaceutical carrier for internal radiation therapy of malignant gliomas. The present study was designed to evaluate the efficacy of intra-cerebral administration of (188)Re-SSS LNC by means of(More)
The infusion of BDNF and NT-3 into Schwann cell (SC) grafts promotes regeneration of brainstem neurones into the grafts placed in adult rat spinal cord transected at T8 (Xu et al., 1995b). Here, we compared normal SCs with SCs genetically modified to secrete human BDNF, grafted as trails 5 mm long in the cord distal to a transection site and also deposited(More)
Intrastriatal implantation of genetically modified cells synthesizing nerve growth factor (NGF) constitutes one way to obtain a long-term supply of this neurotrophic factor and a neuronal protection against an excitotoxic lesion. We have investigated if NGF-loaded poly(d,l-lactide-co-glycolide) microspheres could represent an alternative to cell(More)
Glial cell line-derived neurotrophic factor (GDNF) offers the possibility to stimulate axonal regeneration of mesencephalic dopaminergic neurons, which are affected in Parkinson's disease. Nevertheless, a safe and efficient GDNF delivery system that may be used in clinical trials is still lacking. In a previous study, we showed that GDNF-releasing(More)
This work aims to prospectively record all primary central nervous system tumors (PCNST), in France, for which histological diagnosis is available. The objectives are to create a national registry and a network to perform epidemiological studies, to implement clinical and basic research protocols, and to harmonize the healthcare of patients affected by(More)
By focusing on rat glioma, we elucidated whether new lipid nanocapsules (LNC) were able to improve anticancer hydrophobic drug bioavailability while also overcoming multidrug resistance. Blank LNCs and LNCs loaded with the antineoplastic agent paclitaxel were formulated by an emulsion inversion phase process. Expression of efflux pumps by rat glioma cells(More)
We report on the safety and feasibility of autologous tumor cell vaccination combined with infusion of granulocyte-macrophage colony-stimulating factor by a programmable pump in the treatment of recurrent malignant gliomas. The programmable pump is a promising tool used to infuse cytokines subcutaneously for vaccination. Our trial enrolled nine patients who(More)
The authors report the case of a 14-month-old baby boy with an epidermoid cyst located entirely within the pons and medulla, without an exophytic component. The lesion was examined by computed tomography and magnetic resonance imaging. The child was operated upon three times after two recurrences of the lesion. A suboccipital, subtonsillar approach was used(More)
BACKGROUND Changes in promoter DNA methylation pattern of genes involved in key biological pathways have been reported in glioblastoma. Genome-wide assessments of DNA methylation levels are now required to decipher the epigenetic events involved in the aggressive phenotype of glioblastoma, and to guide new treatment strategies. RESULTS We performed a(More)
