TL;DR: This research presents a novel probabilistic approach to estimating the response of the immune system to laser-spot assisted, 3D image analysis of central nervous system injury.
Journal ArticleDOI
Elevated plasma non-esterified fatty acid levels and insulin secretion in non-diabetic relatives of type 2 diabetic patients.
TL;DR: High non‐esterified fatty acid (NEFA) levels impair glucose‐stimulated insulin secretion from islets derived from non‐diabetic Zucker rats that are genetically predisposed to diabetes.
