BACKGROUND The use of fresh red blood cells (RBCs) is recommended for critically ill patients and patients undergoing surgery, although there is no conclusive evidence that this is beneficial. In this follow-up study, the short-term and the long-term recovery of irradiated, leukoreduced RBCs transfused after either a short storage (SS) or a long storage (LS) period were compared. By consecutive...

BACKGROUND Intraoperative cell salvage (ICS), hereby referred to 'mechanical red cell salvage', has been widely used and proven to be an effective way to reduce or avoid the need for allogeneic red blood cells (RBCs)transfusion and its associated complications in surgeries involving major blood loss. However, little is known about the influence of this technique on the functional state of salva...

Shapes and volume fractions (number and volume) of the red blood cells (RBCs) are important indicators for checking the patient cases. Microcytes, macrocytes, Elliptocytosis, oblate, and prolate are different RBCs shapes related to the blood diseases. The structure, the volume and the number of RBCs cell have direct effects on the electrical characteristics of RBCs. Many mathematical algorithms...

Hemolytic anemia in sickle disease involves both intravascular and extravascular destruction of erythrocytes. Since the latter presumably involves the reticuloendothelial system, we have examined interactions between sickle erythrocytes and macrophages. In erythrophagocytosis assays, 18.9 +/- 7.2% of human marrow macrophages ingest sickle RBCs, while only 3.1 +/- 2.1% ingest normal RBCs. This a...

In healthcare systems, one of the important actions is related to perishable products such as red blood cells (RBCs) units that its consumption management in different periods can contribute greatly to the optimality of the system. In this paper, main goal is to enhance the ability of medical community to organize the RBCs units’ consumption in way to deliver the unit order timely with a focus ...

We have evaluated senescence related changes in canine red blood cells (RBCs) using the biotinylation system, where RBCs are labeled in vivo with biotin at the beginning of their life span, and retrieved from circulation on immobilized avidin at the end of their life span. This approach avoids the controversial use of density gradient centrifugation to collect presumably old RBCs. Furthermore, ...

Poly(2-dimethylamino-ethylmethacrylate) (PDMAEMA) is a cationic polymer when dissolved in a 7.4 pH fluid. Owing to its ionic nature, this polycation interacts with the negatively charged cell membrane surface of red blood cells (RBCs). The electrostatic self-assembly of PDMAEMA on RBCs membrane can be employed for inducing the formation of a polymeric shield camouflaging blood group antigens on...
