IMPORTANCE We observed a significant correlation between cerebrospinal fluid (CSF) levels of tau proteins and α-synuclein, but not β-amyloid 1-42 (Aβ1-42), and lower concentration of CSF biomarkers, as compared with healthy controls, in a cohort of entirely untreated patients with Parkinson disease (PD) at the earliest stage of the disease studied so far.(More)
Improved symptomatic and disease-modifying treatments are needed for Parkinson's disease (PD). Although significant advances have been made in the understanding of PD etiology, the translation of these discoveries into novel transformative therapies has been limited as a result of systemic challenges in PD drug development. Preclinical testing lacks clear(More)
Therapeutic development in Parkinson's disease is hampered by the paucity of well-validated biomarkers that can assist with diagnosis and/or tracking the progression of the disease. Since its inception, the Michael J Fox Foundation for Parkinson's Research has invested heavily in biomarker research and continues to prioritize discovery and development(More)
The development of biomarkers to predict the progression of Parkinson’s disease (PD) from its earliest stage through its heterogeneous course is critical for research and therapeutic development. The Parkinson’s Progression Markers Initiative (PPMI) study is an ongoing international multicenter, prospective study to validate biomarkers in drug-naïve PD(More)
Prediction of epidemics such as Foot and Mouth Disease (FMD) is a global necessity in addressing economic, political and ethical issues faced by the affected countries. In the absence of precise and accurate spatial information regarding disease dynamics, learning-based predictive models can be used to mimic latent spatial parameters so as to predict the(More)
Currently many commercial buildings are not continuously monitored for energy consumption, especially small buildings which constitute 90% of all such buildings. However, readily available data from the electric meters can be used for monitoring and analyzing energy consumption. Efficient utilization of available historical data (from these meters) can(More)
In this paper we build a model of market competition among religious denominations, using a framework that involves incomplete contracts and the production of club goods. We treat denominations akin to multinational enterprises, which decide which countries to enter based on local market conditions and their own " productivity. " The model guides us in(More)
BACKGROUND As in other therapeutic areas, clinical studies in Parkinson's disease (PD) face significant recruitment challenges. However, qualitative surveys suggest that individuals with PD are willing to participate in clinical research. The Michael J. Fox Foundation therefore established Fox Trial Finder in 2011 to facilitate connection between PD(More)
