Search Existing Tissue Requests

The Knight ADRC has supported many investigators at Washington University and at other institutions over the years. We wish to avoid the situation where two investigators study the same research question to avoid duplication of effort and potential conflict. To determine if your topic has already been studied with our resources, please search our database. If you find that your topic or a related topic has been submitted, you may wish to contact the investigator to inquire about their 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 number (e.g. T1004), the full request has been submitted and is either approved, disapproved or in process. If an entry has no ID number, then it represents a submission that has not yet been reviewed. Search terms are applied across an entire requests application including variables not displayed below. A more specific, detailed search may yield better results depending upon your needs.

Project Title: The kinetics of the plasma Aβ biomarkers (Aβ42, Aβ40) in the Adult Children Study (ACS).

Date: December 21, 2021 at 5:02 pm

Request ID: T1402

Aim 1: To measure the levels of Aβ plasma markers (DA and RP for Aβ42, Aβ40) in the ACS cohort.

Aim 2: To identify which demographic (age, family history, ApoE genotype, sex, years of education) hematological (hematocrit, blood cell counts, if available in ACS database) and serum biochemical covariables (creatinine, homocysteine, urea, uric acid, hemoglobin, and serum total proteins, if available

Aim 3: Alternatively, these analysis could be performed at Araclon’s lab if a frozen serum sample would be provided) are significantly associated with the levels of Aβ plasma markers in the ACS cohort. Those statistical significant correlates should be included as potential confounding factors in the multi

Aim 4: To describe the progression of plasma Aβ biomarkers over time in each subject and the variation in the trajectories between subjects in a model adjusted for the relevant confounding factors.
