Search DIAN Data Resource Requests

In order to avoid the situation where two investigators study the same research question, please search our database to determine if your topic has already been studied. If you find that your topic or a related topic has already been submitted, you may wish to contact the investigator to inquire about his/her findings to determine how you might proceed. You may wish to collaborate or modify your request to avoid overlap. The results below reflect requests made since online requests have been accepted. As such, not all fields will have data as certain information, such as aims, were not collected until recently. If an entry has been assigned an ID # (e.g. DIAN-D1004), the full request has been submitted and is either approved, disapproved or in process.

Title:Evaluation of longitudinal trajectories of novel CSF markers of neuronal injury/neuroinflammation

Date of Request:09/13/2017



Aim 1:Perform cross-sectional and longitudinal analyses of clinical, cognitive, structural imaging and biochemical changes according to estimated age of symptomatic onset for standard CSF biomarkers (tau, ptau, and Aβ42) as well as novel ones (VILIP-1, Ng, SNAP-25, YKL-40) in order to evaluate the rate of change of the novel CSF biomarkers as a function of baseline estimated age of symptomatic onset

Date of Request:3/8/2017


Aim 1:To generate a mathematical model explaining onset and progression of PD, CTE and other related neurological conditions as a consequence of CNS trauma

Aim 2:Generate a tentative mathematical rubric for analyzing individual CSF protein biomarker concentrations with existing data pool from ongoing and published research studies

Aim 3:Generate a more comprehensive explaination regarding onset and progression of neurodegenerative conditions merging principles of neuroscience, neuropathology, statistical thermodynamics, kinetics and equilibrium
