Volumetric alterations in the hippocampal subfields of subjects at increased risk of dementia.
Maria-Eleni Dounavi, Elijah Mak, Katie Wells, Karen Ritchie, Craig W Ritchie, Li Su, John T O' Brien
Mar 16, 2020
The hippocampus is one of the first regions to demonstrate atrophy during the prodromal stage of Alzheimer's disease. Volumetric analysis of its individual subfields could provide biomarkers with higher sensitivity than whole...

Power, false discovery rate and Winner's Curse in eQTL studies.
Investigation of the genetic architecture of gene expression traits has aided interpretation of disease and trait-associated genetic variants; however, key aspects of expression quantitative trait loci (eQTL) study design and...
Improving outcomes in high-risk, nonmetastatic renal cancer
High-risk, localized renal cancer is associated with recurrence rates of up to 75% at 10 years. The outcomes of patients at this disease stage depend on optimal patient stratification, surgical management and systemic therapy...
The Strange Use of דגל in Song of Songs 5
