An automatic method for kinetics independent spectrometric analysis is proposed in this study. It uses a non-linear calibration model that explores concentration gradients generated by a flow-batch analyser (FBA) for the samples, dye, and the single standard solution. The procedure

Nutrition can affect the hypothalamus-pituitary-adrenal axis. We hypothesized that early administration of parenteral nutrition (PN) during critical illness reduces plasma ACTH and cortisol concentrations and thereby increases the use of corticosteroids. This is a preplanned substudy of a randomized controlled
