One is about the dissociation of the metabolic sensitivity to insulin from endothelial nitric oxide (NO) release and its vascular protective effects, and the other is on the specificity of the assay of blood nitrates (both 15N-labeled and unlabeled) as indices of NO generation.

In regards to the first issue, recent work by the Accili Laboratory, commented on by Kearney (3), report data on the dissociation between …
