BACKGROUND Infants with severe intraventricular-periventricular hemorrhage (IVH) have higher absolute nucleated red blood cell counts (aNRBC) at birth (a marker of intrauterine hypoxia) than controls. Periventricular leukomalacia (PVL) is known to be associated with prenatal and postnatal events. Whether PVL is also linked to intrauterine hypoxia is unknown. OBJECTIVES To test the hypothesis ...

background: the development of anti-red blood cell alloantibodies remains a major problem in transfusion of blood in thalassemia major patients. also, autoantibodies can result in clinical hemolysis and difficulty in cross-matching blood. we studied the frequency of red blood cell alloimmunization and autoimmunization among thalassemia patients who received regular transfusions in ilam province...

Background: Intraventricular hemorrhage (IVH) is one of the most serious complications of premature deliveries, especially in very low birth weight (VLBW) newborns. The current study compared the number of nucleated red blood cells (NRBCs) in newborns with and without IVH.Methods: This cross-sectional study was carried out on 109 VLBW neonates who were referred to the Neonatal Intensive C...

PURPOSE To assess, in an in vitro model of acute hematoma, whether hemoglobin immobilization by clot and red cell membrane aging can account for the T2 shortening usually attributed to deoxyhemoglobin. METHODS Clotted and heparinized blood samples were packed (100% hematocrit). The apparent magnetization transfer rate (AMTR), T1 and T2 relaxation rates of the samples, and images with a volunt...
