Numerical simulations of light scattering by a biconcave shaped human red blood cell (RBC) are carried out using the finite-difference time-domain (FDTD) method. A previously developed FDTD code for the study of light scattering by ice crystals is modified for the current purpose and it is validated against Mie theory using a spherically shaped RBC. Numerical results for the angular distributio...
The purpose of this study was to characterize red blood cell (RBC) deformability by iron deficiency. We measured RBC deformability to ektacytometry, a laser diffraction method for determining the elongation of suspended red cells subjected to shear stress. Isotonic deformability of RBC from iron-deficient human subjects was consistently and significantly lower than that of normal controls. In g...
Bi-functional antibodies with the ability to bind two unrelated epitopes have remarkable potential in diagnostic and bio-sensing applications. In the present study, bispecific antibodies that recognize human red blood cell (RBC) and the food borne pathogen Listeria monocytogenes (L. monocytogenes) were engineered. The procedure involves initial reduction of a mixture of anti-RBC and anti-Lister...
Malaria is a disease caused by plasmodium parasites transmitted through the bites of female anopheles-mosquito that infect human red blood cell (RBC). The standard malaria diagnosis based on manual examination thick and thin smear, which heavily depends microscopist experience. This study proposed system can identify life stages falciparum in RBC. image preprocessing process was done illuminati...
Abstract The structural integrity of the host red blood cell (RBC) is crucial for propagation Plasmodium spp . during disease-causing stage malaria infection. To assess stability vivax -infected reticulocytes, we developed a flow cytometry-based assay to measure osmotic within characteristically heterogeneous reticulocyte and P. samples. We find that erythroid decreases erythropoiesis maturatio...
Red blood cell (RBC) traits are routinely measured in clinical practice as important markers of health. Deviations from the physiological ranges are usually a sign of disease, although variation between healthy individuals also occurs, at least partly due to genetic factors. Recent large scale genetic studies identified loci associated with one or more of these traits; further characterization ...
Background: The use of conventional stains including Giemsa, Wright and Leishman have become an essential tool for differential diagnosis of cells in peripheral blood. Aims: The aim of the study was to develop a new combination of Leishman-Giemsa (L&G;) stain for avian blood smears and to compare its efficacy with conventional staining methods. Methods:<...
The YT blood group antigen is located on human red blood cell (RBC) acetylcholinesterase. Wild-type acetylcholinesterase, YT1, has histidine at codon 322, whereas the genetic variant of acetylcholinesterase, YT2, has asparagine. This mutation is located within exon 2 of the ACHE gene, an exon that is present in all alternatively spliced forms of acetylcholinesterase. Therefore, acetylcholineste...
Elevated glucose level and low pH have been shown to increase red blood cell (RBC) rigidity. This increased rigidity has been proposed as one factor which mediates the tumor blood flow (TBF) reduction during hyperglycemia by (a) causing RBC entrapment and hence increasing geometric resistance and (b) increasing viscous resistance to blood flow. However, due to the inability to measure these res...
