Red cell aplasia in children is a condition characterised by failure of erythropoiesis, with normal production of white blood cells and platelets. The disorder is either acquired or constitutional (congenital or inherited). The constitutional disorder is usually permanent, while the acquired variety is often transient, and thereby differs from adult pure red cell aplasia. As the treatment and p...

Fructose diphosphate and the triose phosphates are known to accumulate in red blood cells when they metabolize glucose at high rates due to the presence of orthophosphate. This has led to the suggestion that either glyceraldehyde phosphate dehydrogenase or glycerate phosphate kinase is rate-limiting under these conditions. However, the present work shows, by a study of isotope mixing rates and ...

Because of the breakdown of malaria control programs, the constant emergence of drug resistant parasites, and, possibly, climatic changes malaria poses a major problem for the developing countries. In addition, because of the speed of international travel it is being seen with increasing frequency as an imported disease in non-tropical countries. This update explores recent information about th...

Studies during the last three decades have enabled the development of detailed molecular insights into the structural basis of altered function in various inherited red cell membrane disorders. This review highlights our current understanding of molecular and mechanistic insights into various inherited red cell membrane disorders involving either altered membrane structural organization (heredi...

The past two decades have witnessed increased scrutiny regarding efficacy and risk of the once unquestioned therapy of red blood cell (RBC) transfusion. Simultaneously, a variety of changes have been identified within the RBC and storage media during RBC preservation that are correlated with reduced tissue oxygenation and transfusion-associated adverse effects. These alterations are collectivel...

It has been well documented that shear forces effective above a certain magnitude under flow conditions causes damage in blood cells. This damage ranges from slight morphological alteration to the destruction of red blood cells (RBC). The hemolytic trauma to RBC can easily be detected by measuring free hemoglobin level in plasma, however there are no standardized protocols to quantitate subhemo...

T HE APPEARANCE of antigens during cell maturation or cell differentiation can be studied by the demonstration of red cell isoantigens during red cell development. It has been demonstrated that red cell isoantigens are present on normoblasts of all stages of development, including dividing forms.1’2 These findings suggested that the appearance of red cell isoaritigens occurs in an early stage o...

Detection of ABO blood groups through agglutination is the basis of pre-transfusion testing. However, weak agglutination reactions may be obtained with reagent antibodies and are a result of weak expression of A and B antigens on red blood cell surface which may cause a discrepancy in blood group typing. Here, we report a donor which showed discrepancy between red blood cells (forward) and seru...
