Safety is an important dimension of access to green space. When parks are perceived as
unsafe, people are unlikely to derive the health and community benefits from them. In this study…

To investigate the usefulness of 18F-FP-CIT PET for assessing the severity of Parkinson’s
disease (PD) at various clinical stages, 41 patients with PD were divided into early (…

Advances in radionuclide tracers have allowed for more accurate imaging that reflects the
actions of numerous neurotransmitters, energy metabolism utilization, inflammation, and …

Background Genome-wide association studies have identified more than 30 Alzheimer’s
disease (AD) risk genes, although the detailed mechanism through which all these genes are …

Background Plasma glial fibrillary acidic protein (GFAP) has emerged as a promising biomarker
in neurological disorders, but further evidence is required in relation to its usefulness for …

A biological research framework to define Alzheimer’ disease with dichotomized biomarker
measurement was proposed by National Institute on Aging–Alzheimer’s Association (NIA–AA…

We revisit the standard methodology for evaluating proximity to urban services and recommend
enhancements to address existing limitations. Existing approaches often simplify their …

… Prior to the emission scan, a low-dose CT transmission scan was performed for attenuation
correction. The brain emission scan was acquired between 45 and 55 min after intravenous …

Amyloid β protein oligomer (AβO) has been found to be a crucial biomarker of Alzheimer’s
disease (AD). Exploring an accurate detection method of AβO is of great significance for early …

… Scans were performed with a Siemens Biography 64 PET/CT (Siemens, Germany) in
three-dimensional mode. A CT transmission scan was first performed for attenuation correction. …
