Optimization of 6-hydroxydopamine animal model of early stage Parkinson´s disease for the assessment of neurorestorative therapies
Objective: To optimize a simple unilateral partial 6-hydroxydopamine (6-OHDA) lesion protocol that would produce 40-60% striatal dopamine (DA) depletion with detectable motor deficits and to…The role of striatal dopaminergic terminals in early de novo PD patients with speech impairment
Objective: To assess the role of striatal dopaminergic terminals in early de novo (untreated) Parkinson's disease (PD) patients with impairment of speech. Background: Dopamine has…Effect of dopamine and L-3,4 – dihydroxyphenylalanine in treatment of experimental parkinsonism
Objective: To study effect of dopamine and L-3,4 - dihydroxyphenylalanine in treatment of experimental parkinsonism. Background: Prospects of treatment of Parkinson's disease are also closely…Differential expression of cerebral dopamine neurotrophic factor (CDNF) in the hippocampus and in the striatum of LRRK-2 mutant rat model of Parkinson’s disease
Objective: The objective of our study was to characterize the behavioral phenotype of the transgenic LRRK-2 rat in the context of PD model and to…Increasing placebo response in Parkinson’s disease through apomorphine pre-conditioning
Objective: To see whether a placebo response requires pharmacological pre-conditioning with apomorphine. Background: Placebos have been found to affect the patient's brain in a number…The neurosteroid dehydroepiandrosterone sulfate (DHEAS) reverses the dopaminergic deficiencies in mild hepatic encephalopathy: A possible therapeutic issue for the management of parkinsonism in cirrhotic patients
Objective: In the present study, we describe the changes of the dopaminergic system occurring in the cirrhotic rats and concomitantly we investigated the effect of…Role of dopamine and GABA during subthalamic and pallidal deep brain stimulation: Evidence of dopamine release during subthalamic Deep Brain Stimulation
Objective: We recorded the single-unit activity of striatal cholinergic interneurons of healthy monkeys during high-frequency stimulation (HFS) of the subthalamic nucleus (STN) and globus pallidus…Comparison of DAT scan, cardiac MIBG scintigraphy, and cerebrospinal fluid 5HIAA levels in Parkinsonian syndrome
Objective: To assess the associations of presynaptic dopamine transporter (DAT scan), cardiac 123I-meta-iodobenzylguanidine (MIBG) scintigraphy, and cerebrospinal fluid (CSF) levels of 5-hydroxyindole acetic acid (5HIAA)…AMP kinase regulates ligand-gated K-ATP channels in substantia nigra dopamine neurons
Objective: To characterize the effect of AMP-activated protein kinase (AMPK) on ATP-sensitive K+ (K-ATP) channels on substantia nigra compacta (SNC) dopamine neurons in slices of…Evaluation of regional changes in striatal DAT binding in a progressing Parkinson’s disease (PD) cohort: Lessons for imaging biomarker assessment in disease-modifying therapeutic trials
Objective: To evaluate subregion-dependent striatal changes in dopamine transporter (DAT) binding using 123-I Ioflupane SPECT in PD participants in the Parkinson Progression Marker Initiative (PPMI)…
