Characterizing Cutaneous α‐Synuclein Deposition and Seeding Activity in Parkinson's Disease Subtypes

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Cutaneous phosphorylated α‐synuclein (p‐syn) and α‐synuclein seeding activity are promising biomarkers for Parkinson's disease (PD), but their clinical value remains uncertain due to disease heterogeneity. This study evaluates these two biomarkers in PD patients to inform phenotype‐specific diagnosis and disease severity assessment ...

Decontamination of Sludgelike Uranium-Bearing Wastes: Decontamination Feasibility Judgment Using Radon Emanation Coefficients and Development of Decontamination Methods [PDF]

open access: yesJournal of Nuclear Science and Technology, 2008
It is difficult to decontaminate sludgelike uranium-bearing wastes by wet methods, such as employing nitric acid for selective uranium dissolution. This is because these uranium-bearing wastes have very small pores inside which uranium is deposited, and the decontamination liquid cannot get inside the pores and so cannot dissolve the uranium.

Baseline Neuroinflammation Stratifies TSPO‐PET Response to Disease‐Modifying Therapy in Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To investigate which baseline clinical and imaging characteristics best predict TSPO‐PET‐measurable reduction in glial activation following treatment of multiple sclerosis (MS), to utilize this information for designing more efficient biomarker‐based clinical trials targeting glial activation.

Evaluation of Radionuclides Concentration in Natural Samples Used in Viral Industry

open access: yesJournal of Scientific Research in Science
The radiological control of naturally occurring radioactive materials (NORMs) in industries such as mining is governed by several regulations. To determine the activity concentrations of long-lived natural radionuclides — such as 238U, 226Ra, 232Th and ...

Natural Frequencies of Levodopa‐Induced Dyskinesia in Parkinson's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Abnormal involuntary movements, known as dyskinesias, are common complications of levodopa treatment in patients with Parkinson's disease and can significantly impair quality of life. The underlying pathophysiology remains unclear, and current therapeutic options are limited.
