The soluble transferrin receptor as a marker of iron homeostasis in normal subj...
Brandâo, M.; Oliveira, J.; Bravo, F.; Reis, J.; Garrido, I.; Porto, G.Background and Objectives. The soluble transferrin receptor (sTfR) is a clinical marker of erythropoietic activity, also used in the diagnosis of iron deficiency. In the present paper we explore the meaning of this parameter in normal physiological conditions of iron homeostasis and in the setting of iron overload due to hereditary hemochromatosis (HH). Design and Methods. Reference values for sTfR were establi...
Influence of Cellular Density on Determination of EC50 in Microalgal Growth Inh...
Moreno-Garrido, I.; Lubián, L. M.; Soares, A. M. V. M.Growth inhibition tests for copper were carried out on four marine microalgal species: Chlorella autotrophyca, Nannochloris atomus (Chlorophyceae), Phaeodactylum tricornutum (Bacillariophyceae), and Isochrysis aff. galbana (Primnesiophyceae). The test initial cellular densities were reduced to 50 and 10% from the recommended initial cellular density in most of standardized assays. OECD test protocol (originally...
