WebHematocrit, serum ferritin, and unsaturated iron-binding capacity were significantly affected by inflammation while reticulocyte hemoglobin content and other parameters were not. The cut-off value of reticulocyte hemoglobin content for diagnosing iron deficiency anemia was 27.2 pg, with a sensitivity of 87.5% and a specificity of 92.9%. WebOur final model provided valuable insight on target binding-related parameters, such as the Hill coefficient γ (estimated to be 1.6), binding constant K H (estimated to be 1450 µM), and the amount of total hemoglobin R tot (estimated to be 2.13 µmol). As the dose selection of a compound with positive cooperative binding is tricky and ...
