Abstract

Red blood cells (RBCs) are an essential component of blood. A method to include the particulate nature of blood is introduced here with the goal of studying circulation in large‐scale realistic vessels. The method uses a combination of the Lattice Boltzmann method (LBM) to account for the plasma motion, and a modified molecular dynamics scheme for the cellular motion. Numerical results illustrate the quality of the model in reproducing known rheological properties of blood as much as revealing the effect of RBC structuring on the wall shear stress, with consequences on the development of cardiovascular diseases. magnified image

We set out to ascertain the numbers of fetal cells that enter the maternal blood stream during pregnancy. Samples of 15-16 ml of whole blood were collected from 225 women--mostly 10-18 weeks pregnant--and then processed by charge flow separation, a novel method based on free flow electrophoresis in

Background: Nucleated red blood cells (NRBC) in blood specimens compromise the automated white blood cell (WBC) count on most hematology analyzers. This makes it necessary to correct the WBC count by subtracting separately counted NRBC by manual microscopy. In addition, it is clinically important to
