BACKGROUND Transfusion of blood at the limits of approved storage time is associated with lower red blood cell (RBC) post-transfusion recovery and hemolysis, which increases plasma cell-free hemoglobin and iron, proposed to induce endothelial dysfunction and impair host defense. There is noted variability among donors in the intrinsic rate of storage changes and RBC post-transfusion recovery, y...
The cell in Image BCI-01 is a nucleated red blood cell (RBC). Although nucleated RBCs do not normally appear in the peripheral blood of an adult, it is not unexpected in this patient’s condition owing to hematopoietic bone marrow stress. Nucleated RBCs are immature erythrocytes that still retain their nucleus. The cell in this image is typical of those most often seen in the peripheral blood of...
In order to determine the conditions under which monocytes are able to destroy red cells coated with antibody in vitro in the presence of fluid-phase IgG, human peripheral blood monocytes and red cells coated with IgG anti-D antibody were incubated in media containing lgG (neat serum or medium containing 1000 tg/ml of purified IgGI). Although phagocytosis was markedly inhibited in media contain...
We present a novel optical methodology including both instrumentation and theory aimed at retrieving the full viscoelastic information of cell membrane material properties. Red blood cells (RBC) are chosen for this study because of their simple structure, which consists of a bi-layer cell membrane supported by a cytoskeleton enclosing a homogeneous fluid. The full complex modulus of RBC in term...
background: anemia is common throughout the world, remarkably in developing countries. our aim is to calculate normal hemoglobin and other hematological indices in southwest of iran. materials and methods: a random selection of 500 healthy males and 500 healthy females was done in the age group of 13 to 65 years. a complete blood count (cbc) was performed in all participants. results: hemoglobi...
BACKGROUND Folate has been shown to play a complex but unclear role in carcinogenesis, with some studies showing that low folate intake protects against early carcinogenesis while high folate intake promotes advanced carcinogenesis. Other studies have shown that high folate is associated with decreased breast cancer risk and overall survival, yet others found no such association.This study ther...
We suggest that Diffuse Correlation Spectroscopy (DCS) measurements of tissue blood flow primarily probe relative red blood cell (RBC) motion, due to the occurrence of multiple sequential scattering events within blood vessels. The magnitude of RBC shear-induced diffusion is known to correlate with flow velocity, explaining previous reports of linear scaling of the DCS "blood flow index" with t...
INTRODUCTION Folate deficiency is assessed by serum and red blood cell folate measurements. Nevertheless, no consensus for the lower limit of serum folate reference values exists. We investigated the appropriate use of RBC folate to detect folate deficiency and the relationship between serum and RBC folate and with other parameters such as vitamin B12 and homocysteine in order to propose serum ...
this study was conducted to evaluate the effect of prebiotic short saccharomyces cerevisiae yeast cell wall (ycw) on growth , nutrition and survival rates , blood indices of rainbow trout (oncorhynchus mykiss) were studied . 600 pieces of salmon with an average weight of (1 ± 20) g 4 treatments and 3 replications (each replication 50 pieces of fish) groups. treatments 1, 2, 3 and 4, respectivel...
