BackgroundHuman lactate formation is typically attributed to hypoxia, but it may actually be due to the influence of norepinephrine. MethodsA lactate gradient was measured from the first few drops of blood obtained after application of a lancet to a finger pad. However, the blood needed to be carefully obtained according to this protocol. ResultsThe measured lactate gradient was surprisingly large in some circumstances, and was not correlated with any of the other measured parameters such as oxygen or carbon dioxide blood levels. There were hints in the data that the lactate gradient seemed to be influenced by sympathetic noradrenergic nervous system activity. ConclusionsThe lactate gradient is relatively easily obtainable, and may reflect conditions causing enhanced sympathetic activity.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
