Zinc protoporphyrin (ZnPP) is a normal metabolite that is formed in trace amounts during heme biosynthesis. The final reaction in the biosynthetic pathway of heme is the chelation of iron with protoporphyrin. During periods of iron insufficiency or i

Background: The hepatic iron concentration (HIC) is widely used in clinical practice and in research; however, data on the variability of HIC among biopsy sites are limited. One aim of the present study was to determine the variability of HIC within

Given the widespread interest in antioxidant nutrients, we have developed a new procedure that will permit the automated determination of plasma ascorbic acid (AA) concentration with a Roche Fara centrifugal analyzer. After the deproteinization of pl

Increased zinc protoporphyrin/heme (ZPP/H) ratio has been used in pediatrics to screen for iron deficiency and lead poisoning. This study was conducted to determine whether common hereditary hemoglobin disorders (alpha- and beta-thalassemia traits, h

Nutrition is a developing facet of patient care that can be enhanced by appropriate laboratory support. The importance of the laboratory is underscored by the growing interest and appreciation for marginal malnutrition that can only be diagnosed by b

Most nutrition laboratory testing relies on serum concentrations of ingested nutrients, their coenzymes, proteins, or lipids. Alternatively, functional tests measure a specific physiological process or biochemical reaction. We compared these two appr

This instrumental method for total urinary nitrogen (TUN) is based on the principle of gas-phase chemiluminescence. Results correlate well with measurements of TUN by the Kjeldahl method, which has long provided the means to calculate nitrogen balanc

Clinical investigations of laser photobioactivation, or biostimulation, might be differently designed and more fruitful if knowledge of basic biochemical mechanisms were better understood. In this investigation, biochemical events identified as respo

Zinc protoporphyrin (ZPP) is a normal metabolite that accumulates at trace amounts in erythrocytes during hemoglobin synthesis. In states of inadequate iron delivery to developing red cells, excess ZPP forms as a by-product of the heme biosynthetic p
