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…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…Andrograholide protect microglial activation via inhibiting mitochondrial ROS generation and NLRP3 inflammasome activation in in-vitro and in-vivo model of Parkinson’s disease
Objective: Parkinson's disease (PD) is a distressing neurodegenerative disorder effecting nearly 2-3% of the total population greater than 65 years old . Several mechanisms have…A single nigral injection of human ENGRAILED-1 induces long-lasting behavior benefit in an experimental primate model of Parkinson Disease
Objective: Evaluate the efficacy of a single nigral injection of human ENGRAILED-1 (hEN1) in a recognized chronic MPTP macaque model. Background: EN1 homeoprotein has been…Assessment of neuronal morphology to determine the differential susceptibility to Parkinson’s disease using MPTP in two genetically distinct mice strains
Objective: To delineate the contribution of neuronal-dendritic structure in the substantia nigra and striatum, in conferring differential susceptibility to Parkinson’s disease, using two genetically distinct…Neuroprotective actions of red propolis extract and formononetin in a rat model of Parkinson’s disease
Objective: To evaluate the effects of the hydroalcoholic extract of red propolis (HERP) and one of its major compounds, formononetin (FN), against the motor symptoms…Substantia Nigra (SN) Hyperechogenicity as seen in Transcranial Sonography (TCS) is a reliable disease progression marker from Stage I to Stage II in Early Onset Parkinson’s Disease (EOPD)
Objective: To test the hypothesis that SN hyperechogenicity seen in transcranial sonography (TCS) can be used as a reliable disease progression marker from stage I…Micro structural Changes in Substantia Nigra are associated with Severity of Parkinson’s Disease.
Objective: The aim of this study was to apply diffusion tensor imaging (DTI) to evaluate atrophy of the Substantia Nigra pars compacta (SNc), the pathological…
