Red blood cell (RBC) aggregation and its influence on non-Newtonian nature of blood in microvasculature

Influence of Graded Alterations of Red Blood Cell Aggregation on in Vivo Blood Flow Resistance

Effect of Thyroid Dysfunctions on Blood Cell Count and Red Blood Cell Indice

Abstract Background Thyroid hormones have a crucial role in metabolism and proliferation of blood cells. Thyroid dysfunction induces different effects on blood cells such as anemia, erythrocytosis leukopenia, thrombocytopenia, and in rare cases causes’ pancytopenia. It also alter RBC indices include MCV, MCH, MCHC and RDW. Thus this study attempted to evaluate effect of hypo & hyperthyroi...

Detection and characterization of red blood cell (RBC) aggregation with photoacoustics

Red blood cells (RBCs) aggregate in the presence of increased plasma fibrinogen and low shear forces during blood flow. RBC aggregation has been observed in deep vein thrombosis, sepsis and diabetes. We propose using photoacoustics (PA) as a non-invasive imaging modality to detect RBC aggregation. The theoretical and experimental feasibility of PA for detecting and characterizing aggregation wa...

Influence of non-Newtonian viscosity of blood on microvascular impairment.

The present research investigated the role of blood viscosity on flow within a microvascular network to identify the conditions of blood flow stagnation. When the yield stress of blood was less than 0.005 Pa, there were no stagnant regions in the microvasculature. However, when the yield stress increased to 0.05 Pa, stagnant or reduced flow areas began to appear, which grew and expanded rapidly...

Reduced expression of CD47 during murine red blood cell (RBC) senescence and its role in RBC clearance from the circulation.

BACKGROUND Almost 2 percent of murine blood red blood cells (RBCs) are destroyed each day and are replaced by fresh RBCs generated through the process of erythropoiesis. RBCs to be destroyed are phagocytosed by macrophages in the reticuloendothelial system, especially in the spleen. CD47 molecules on RBCs may regulate the susceptibility of RBC to destruction by phagocytosis because its recognit...
