Nigral microvasculature imaging in Parkinson’s disease
Objective: The goal of this work is to image the microvasculature of the midbrain, in particular the substantia nigra in Parkinson’s disease (PD) patients using…Lack of Toll-like receptor 4 is associated with accumulation of alpha-synuclein in the midbrain Parkinson’s disease mice.
Objective: In this study we aimed to investigate the potential role of Toll-like receptor 4 (TLR4) in mediating both the dopaminergic neuron loss and alpha-synuclein (alpha-SYN)…Neurovascular and immune determinants of selective vulnerability of dopaminergic neurons in Parkinson’s Disease
Objective: We aimed to investigate the contribution of glial cells activation and immune cells infiltration in the selective vulnerability of dopaminergic neurons within the midbrain…The effect of short-term treadmill exercise in the alpha-synuclein preformed fibril rat model of Parkinson’s disease
Objective: To determine how treadmill exercise impacts behavior and Parkinson-related pathology in the alpha-synuclein (a-syn) preformed fibril (PFF) model. Background: Exercise is often recommended by…Burden of COVID-19 among patients with Parkinson’s disease and associated clinical outcomes: Evidence from a meta-analysis
Objective: To understand the burden of covid-19 among patients with Parkinson’s disease and associated clinical outcomes. Background: COVID-19 has affected millions of patients around the…Machine Learning (ML) Prediction of Parkinson’s Disease (PD) Risk and Nigral Neuron Density
Objective: To investigate associations between nigral neuron density and ML-based PD risk prediction. Background: Early identification of persons at high risk for developing PD is…Digenic R1441G-LRRK2 and Parkin mutations in Parkinson’s Disease: first clinicopathological case report.
Objective: To report a clinicopathological case of digenic PD with R1441G- LRRK2 and PRKN mutations. Background: Digenic inheritance of R1441G-LRRK2 and PRKN mutation is extremely…Compartment-specific blockade of dopamine uptake in nigrostriatal pathway reveals role for nigral dopamine function in movement frequency in open-field
Objective: Inhibition of tyrosine hydroxylase activity in the substantia nigra (SN) produces a significant reduction in locomotor motor activity commensurate with decreased dopamine (DA) content…Automatic Detection of Nigrosome Degeneration in Susceptibility-Weighted MRI for Computer-Aided Diagnosis of Parkinson’s Disease Using Machine Learning
Objective: Automatize the detection of ‘swallow-tail’ appearance in substantia nigra dopaminergic neurons using MRI for more robust tests on Parkinson’s disease (PD) diagnosis. Background: Differential…Investigating Substantia Nigra Damage using Fully Automated Segmentation of Neuromelanin MRI in Early Parkinson’s Disease
Objective: Development of reliable imaging biomarkers of dopaminergic cell neurodegeneration is crucial to facilitate therapeutic drug trials in Parkinson's disease (PD). Neuromelanin-sensitive (NM) MRI techniques…
