Longitudinal Change of Substantia Nigra Hyperechogenicity in Parkinson’s Disease Cohort
Objective: To analyze whether the size of SN+ is differentially affected depending on disease duration. Secondly to analyze the interaction between a range of clinical…Targeted deep sequencing of brain DNA for detection of somatic point mutations in synucleinopathies
Objective: To detect relevant somatic "point mutations" (single nucleotide variants- SNVs) in brain-derived DNA in synucleinopathies. Background: There is increasing recognition that neurons may harbour…Sequencing of single human nigral dopaminergic neurons for somatic copy number variants
Objective: To detect somatic DNA copy number variants (CNVs) in dopaminergic neurons isolated from human substantia nigra, using shallow whole genome sequencing (WGS). Background: Somatic…The trace of substantia nigra hyperechogenicity: a clinical observation
Objective: To present an empirical observation regarding transcranial ultrasound in movement disorders and scalp sebum smear. Background: Transcranial ultrasound (TUS) detects substantia nigra hyperechogenicity (SN+) in…Transcranial ultrasound in atypical parkinsonism: how reliable is it in real clinical practice? A multi-centre comprehensive study
Objective: To assess real clinical practice usefulness of transcranial ultrasound in atypical parkinsonism differential diagnosis, and to perform a critical analysis of previous literature in…Substantia Nigra Hyperechogenicity in Parkinson’s Disease and Essential Tremor and its Association with Premotor Symptoms of Parkinson’s Disease
Objective: To compare the frequency of Substantia Nigra hyperechogenicity (SN+) in patients with essential tremor (ET) and Parkinson’s disease (PD), to determine the frequency of…Evaluation of nigral neuronal apoptosis during postnatal development and adulthood of mice strains with differential sensitivity to MPTP
Objective: Compare nigral neurons in C57BL/6J, CD-1 and their F1 crossbreds with respect to developmental apoptosis in the nigra during postnatal and to assess MPTP-induced…Caudal posterior substantia nigra iron increases longitudinally in Parkinson’s disease
Objective: To investigate spatial patterns and temporal evolution of substantia nigra (SN) iron accumulation in Parkinson’s disease (PD) using quantitative susceptibility mapping (QSM), an indirect…Evaluating Volume Changes in the Substantia Nigra Pars Compacta (SNc) in Parkinson’s Disease (PD) in a Study-Specific Magnetic Resonance Imaging (MRI) Template
Objective: To characterize the topography of SNc involvement in PD patients using neuromelanin (NM)-sensitive MRI (NM-MRI). Background: PD is characterized by the progressive loss of…Imaging biomarker for progression of motor symptoms in advanced Parkinson’s disease
Objective: The aim of the present study is to clarify correlation between motor deficits and dopaminergic neuronal loss in advanced Parkinson’s disease (PD). Background: Series…
