We examined whether the radioisotope labeling procedure can be replaced by a simple calculation of RCM from the values of venous blood hematocrit and plasma volume, using an empirical factor (Ratio f) equal to the mean ratio between whole-body and venous hematocrit. A retrospective study was ...

Red blood cells (RBCs) constitute ∼40% of the volume of blood. They are deformable biconcave disks that preferentially flow in the center of vessels, rather than near the wall, leaving a plasma-rich zone of 2 to 6 μm near the endothelial layer (Phibbs, 1968, Blackshear et al., ...
The white blood cell/platelet fraction we analysed for the correction was comprised of both white blood cells and platelets at a ratio of 1:19 and was analysed in its entirety. Thus it is not known what level of cytokines came from either white blood cells or platelets alone. To correct f...
The “pump-leak” model of Tosteson and Hoffman (1960) presented an elegant and simple paradigm for regulation of red blood cell (RBC) cation content and volume. It emphasised the importance of a specific, ouabain-sensitive, Na+/K+ pump, driven by ATP, a
Circadian clocks coordinate mammalian behavior and physiology enabling organisms to anticipate 24-hour cycles. Transcription-translation feedback loops are thought to drive these clocks in most of mammalian cells. However, red blood cells (RBCs), which d
Conclusion Incorporation of the pre-transfusion Hb value in the calculation of RBC transfusion volume may achieve the desired Hb threshold and hence reduce the need for further transfusion.doi:10.1136/archdischild-2014-307384.813Mohammed Bahari

Evaluated parameters are the red blood cell number (RBC) per µL blood, hemoglobin (Hb) in mmol/L, hematocrit (HCT) in %, mean cell volume (MCV) in fL, mean cell hemoglobin (MCH) in fmol of Hb monomers and mean corpuscular hemoglobin concentration (MCHC) in mmol/L. Fo...
Calculation of Mean Cell Volumes at Various Osmolalities For the analysis of these experiments, it was useful to be able to estimate the MCHC of cell populations at various osmolalities. These estimations were performed by assuming that the cells behaved as osmometers and changed their water conte...
