Red Blood Cell Aggregation Characterization: Quantification and Modeling Implications of Red Blood Cell Aggregation at Low Shear Rates
Red blood cells (RBCs) are the most abundant cells in human blood, representing 40 to 45% of the blood volume (hematocrit). These cells have the particular ability to deform and bridge together to form aggregates under very low shear rates. The theory and mechanics behind aggregation are, however, …

Red blood cell pathophysiology : comparative and diagnostic aspects
… the haemolytic anaemia. Since black rhinoceros red blood cells were shown to be susceptible to oxidative stress, the first stage of the work focused on the characterisation of the hexose monophosphate shunt in these cells. Results were compared to human red blood cells. To determine how these …

Studies on the nature of red blood cell hemolysis on storage and the nature of the red blood cell membrane acetylcholinesterase
… view that the acetylcholinesterase (AChE) of the red blood cells (RBC) is concerned with the maintenance of the integrity of the cells Anderson and Pethica (9) have reported that in stored citrated blood, the release of RBC ^ChE seemed to coincide with the onset of hemolysis. In vivo (10, 11) and …

Nonlinear Dynamical Analysis Of Microvascular Red Blood Cell Flow
Microvascular red blood cell (RBC) flow is an enormously complex and dynamically variable process. Variations appear as temporal fluctuations within vessels, and spatially, along or between vessels in a network. These variations occur on many different time scales and highlight microcirculatory …

Automatic red blood cell counting based on particle area
In medical area, red blood cell (RBC) counting and analysis contributes important information in pathological diagnosis regarding disease such as anemia and low level of hemoglobin concentration. Normally the blood sample is processed in laboratory using hematology analyzer and blood smear is …

Studies on the red blood cell membranes and their acetylcholinesterace
"For a better understanding of the question of the structure and the properties of the RBC membranes, investigations on the localization and the nature of association of the ACHE molecules on them could be quite profitable . It was therefore decided to carry on some investigations along these …

Functional Investigation of Genetic Determinants of Red Blood Cell Traits
… thousands of genetic loci associated with blood cell traits. However, the identification and interpretation of candidate causal variants and genes remain challenging. With increasing power to detect genetic associations, many loci reveal multiple statistically independent signals, which - …

Microfluidic devices for analysis of red blood cell mechanical properties
Decreased deformability of human red blood cells (RBCs) is both a cause of disease and biomarker for disease (1). To traverse blood capillaries, the biconcave disk-shaped RBC must deform dramatically, since the diameter of the unconstrained RBC is larger than that of the capillaries. If the RBC …

Homeostasis and volume regulation in the Plasmodium falciparum infected red blood cell
… homeostasis of Plasmodium falciparum infected red blood cells, namely how infected cells retain their integrity for the duration of the parasite asexual reproduction cycle. The volume and shape changes of infected cells were measured and characterized at femtolitre resolution throughout the …

Application of PEPT to track a single labelled red blood cell in vitro
… interest. Apart from these applications, we explored the possibility that PEPT could also be applied to the tracking of a red blood cell. As the progress of this feasibility study remained only at the preliminary stage, this thesis seeks to describe the main factors which would be involved in …

Identification of malaria parasite-infected red blood cell aptamers by inertial microfluidics SELEX
… of infection where parasites develop within red blood cells (RBCs). Infected RBCs can adhere to the host microvasculature, triggering inflammatory responses in affected organs that contribute to the pathophysiology of life threatening cerebral malaria and pregnancy-associated malaria. The …

The relevance of red blood cell deformability in the pathophysiology of blood disorders
Red blood cells (RBCs) play a crucial role in delivering oxygen to the body tissues. During the 120 days of their lifespan, average RBCs would circulate for approximately 500,000 times and undergo repeated deformations in small blood capillaries and splenic cords. Increased RBC clearance in the …

The Effect of Red Blood Cell Velocity on Oxygenation Measurements using Resonance Raman Spectroscopy
… have demonstrated that exposure of oxygenated red blood cells to laser illumination may result in photo-induced displacement of oxygen from hemoglobin. In this study, an in vitro model was used to evaluate the relationship between this photo-induced effect and the red blood cell velocity. A …

Development of a protocol to examine red blood cell functional adaptations to intermittent hypoxia
… effects of intermittent hypoxia (IH) on human red blood cell (RBC) physiology. While IH contributes to conditions such as sleep apnea and cardiovascular disease, its direct impact on RBC function remains poorly characterized. The protocol isolates IH exposure as an independent variable and …

Perioperative Allogenic Red Blood Cell Transfusion: Available Guidance and Audit of Appropriateness in Liver Resection
Red blood cells are commonly administered during the perioperative period, however our understanding of available guidance informing transfusion decisions as well as appropriateness of current practice is not well understood. Blood transfusions are associated with post-operative morbidity and …

The Effect of a PUFA Diet on Human Red Blood Cell Levels of 2, 3-DPG
<p>Fasting blood was collected at weekly intervals and the level of 2,3-DPG of the red blood cell was determined in 15 male subjects age 28 to 57 with serum cholesterol levels greater than 250 mg%. A lactovegetarian diet containing no cholesterol, a high level of dietary fiber and a P/S ratio of …
