Influence of Systemic Interleukin-6 on the Inverse Association between Your-Choice American Heart Diet and a 41-Year Mortality Risk from Coronary Heart Disease among Men
Our premise is systemic inflammation measured as plasma interleukin-6 levels medicates the association between whole diet and long-term mortality risk from coronary heart disease independent of genes.

Expanding The Model Of Item Writing Expertise: Cognitive Processes And Requisite Knowledge Structures
An understanding of test takers’ response processes and knowledge structures is used to predict the psychometric properties of the items. This same knowledge of test takers’ responses and knowledge structures is used to construct items that measure specific aspects of the test framework, e.g., reasoning versus problem solving.
