Elevated Levels of α-Synuclein Oligomer in the Cerebrospinal Fluid of Drug-Naïve Patients with Parkinson's Disease
Background and Purpose The detection of α-synuclein in the body fluids of patients with synucleinopathy has yielded promising but inconclusive results, in part because of conformational changes ofExpand
Sagittal Abdominal Diameter Is a Strong Anthropometric Measure of Visceral Adipose Tissue in the Asian General Population
OBJECTIVE Finding the anthropometric measure of visceral obesity is essential to clinical practice, because it predicts cardiovascular and metabolic risks. Sagittal abdominal diameter (SAD) has beenExpand
Covalent Modification of Multiwalled Carbon Nanotubes with Imidazolium-Based Ionic Liquids: Effect of Anions on Solubility
Multiwalled carbon nanotubes (MWCNTs) were covalently modified with imidazolium salt-based ionic liquids (ILs). Coupling of acid chloride-functionalized MWCNTs with commercially availableExpand
Non-Motor Off Symptoms in Parkinson's Disease
The aim of this study is to elucidate the clinical spectrum and frequency of non-motor symptoms during off periods (NMOS) in Parkinson's disease (PD) patients with motor fluctuation. We comparedExpand
