This thesis develops a mesoscopic technique based on the numerical concepts of Lattice Boltzmann Method (LBM) to simulate blood flow in microvessels. The central theme of the thesis is to simulate the two- dimensional elastic deformation of Red Blood Cells (RBCs), and stream- ing under various types of loadings in the systemic microvessels. Two types of elastic deformation of RBCs that arise from the RBC-plasma and RBC- RBC interaction have been studied by using the most common Two-Dimensional LBM abbreviated as the D2Q9-LBM model. Since the model cannot handle the deformation of the cell inde

Hemoglobin is an oxygen binding protein in erythrocytes. Hemoglobin is composed of four polypeptide chains. During the fetal stage the type of hemoglobin called fetal hemoglobin (HbF) dominates. After birth HbF is replaced by adult hemoglobin (HbA). HbF persists in concentrations less than 1%. Elevated concentration of HbF in adults exists in different conditions, Talassemi for example. When the uterus is damaged and the fetus doesn’t feel well its blood can pass the placenta barrier and enter the blood stream of the mother. A venous blood sample from the mother is analyzed to determine the st

Many attempts have been made to quantify cardiac output using both invasive and non-invasive techniques. The results have generally been poorly reproducible and comparisons of techniques have yielded highly variable values. A single breath inert gas method was used in the study, since it offers several advantages over previous methods, chiefly its speed of measurement, and the controlled manner in which it is performed. The method observes the uptake of a semi-soluble inert gas (Freon-22) with respect to an insoluble marker, and calculates cardiac output (pulmonary flow) from the slope of the

Blood flow is an important measurement in the diagnosis of cardiovascular diseases – the main cause of death globally. Cardiovascular diseases are often associated with atherosclerosis, which is a condition that causes the narrowing of arteries due to a buildup of lipids on the wall of the arterial vessels. Atherosclerosis occurring in the upper or lower limbs (referred to as peripheral arterial diseases) may lead to heart attack, stroke or severe health complications. Early detection of peripheral arterial diseases will enable primary prevention, and thus a reduction in morbidity, mortality a

Polymorphisms of platelet glycoproteins (GPs) are frequently targets for anti-platelet antibodies. At least 19 antigenic polymorphisms have been identified on platelet GPs. Antibodies against the HPA-lb polymorphism (a Leu to Pro switch at amino acid residue 33 of the IIIa sub-unit of GP IIb/Illa) have been attributed to as much as 90% of all cases of neonatal alloimmune thrombocytopenic purpura and posttransfusion purpura in caucasians. The HPA-lb polymorphism has also been equivocally associated with coronary artery disease, particularly early onset (<60 years of age) myocardial infarction.

The possibilities of the method of computerized capillaroscopy for studying the structure of the capillaries of the skin of the hands after exposure to temperature are considered. With local frostbite, there is a lack of sensitivity and insufficient expression of blood vessels, their blanching caused by constriction. The capillaroscopic picture is relatively normal, however, some characteristic changes can be observed: the blood flow slows down, external thinning of the vessel walls is observed, the capillaries are somewhat deformed, some of them empty.

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, not yet completely understood. The purpose of this work is to provide a novel method to analyze, understand and mimic blood behaviour in microcirculation. The main objective is to develop a methodology to quantify and characterize RBC aggregates and hence enhance the current understanding of the no

The glycaemic index (GI) is a measurement used to classify foods according to their potential for raising blood glucose levels.

Rapid analysis methods (in vitro) are being developed and evaluated worldwide, and in many cases the values obtained have correlated well with the G

Motivation: Red blood cells (RBCs) are the most common cells in the blood due to their high concentration. The RBC has a deformable membrane enclosing a jelly-like fluid known as the cytosol. For many years, the dynamics of RBCs has attracted growing interest both numerically and experimentally in various fields of research on biological systems. Owing to their high deformability, RBCs exhibit complex dynamic behaviours in micro-vessels where Reynolds numbers (Re) are less than unity (Re < 1).

Correlation of computed estimates of PAP to actual measurements showed that these equations were greater than 92% accurate within 1.84 mmHg. In addition, while the RDP-PAP relationships were wholly dependent on FV, it was shown t

A new lattice-Boltzmann finite-element method is used to simulate large numbers of deformable red blood cells and platelets in suspension for the investigation of stress-mediated platelet-deposition mechanisms in blood. The coupled lattice-Boltzmann finite-element method provides the novel ability to simulate hundreds of realistic and deformable red blood cells and produce continuum-scale physics at physiologic hematocrit and low arterial-shear rates. The new method is developed and shown to produce single red blood cell deformation consistent with experimental results in flow chambers. Simu

Venous thromboembolism (VTE) is a significant preventable complication that causes morbidity and mortality not only in hospitalised patients, but also in healthy individuals. Pharmacological and mechanical prophylactic methods are available. Pharmacological methods, although are effective in reducing the incidence of VTE, the bleeding risk associated with their use is a major drawback. Besides pharmacological methods, clinical practice guidelines also recommend the use of mechanical methods (NICE, 2010b). The rationale for using mechanical methods is to increase venous return and decrease the

ABSTRACTBackground: Determination of blood loss can be a crucial factor at surgical procedures, especially when the amount of blood is small and mixed with other fluids. The existing methods to measure this are still not supported with evidence enough.Aim: To validate the accuracy of the HemoCue® system (HemoCue, Ängelholm, Sweden) at estimation of blood loss in a setup where blood is mixed with saline and saliva.Materials and methods: The haemoglobin concentration of defibrinated horse blood was measured using the haematology analysers Hemocue® 201+ and Hemocue Plasma/Low Hb Photometer.

Many medical therapies, such as thermal tumor detection and hypothermia cancer treatments, utilize heat transfer mechanisms of the body. The focus of this work is the development and experimental validation of a method to simultaneously estimate thermal conductivity, volumetric specific heat, and perfusion of in-vivo tissue. The heat transfer through the tissue was modeled using a modified Pennes' equation. Using a least-squares parameter estimation method with regularization, the thermal properties could be estimated from the temperature response to the known applied heat flux. The method was

One is only for thick blood vessels, and another is for thick-and-fine blood vessels. The thick blood vessels are easy one and fine blood vessels are the hard one for the vessels extraction algorithm. First we extract thick blood vessels and calculate accuracy. Then conduct the thick-and-fine blood vessels extraction algorithm and accuracy bases on the thick blood vessels extraction algorithm. At least, we compare the difference in accuracy and picture betwee

Compared to other diseases, cardiovascular disease is difficult to detect by the general public since it is less obvious symptoms. In other words, Cardiovascular disease is a major disease can not be ignored. How to diagnose and prevent cardiovascular disease, blood pressure is considered as an important indicator. However, conduct of blood pressure measurements needs medi
