Conductometric study of erythrocytes during centrifugation. II. Erythrocyte deformability
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1995Erythrocyte deformability was studied by continuous reading of sediment conductance during centrifugation. The decrease in sediment conductivity during centrifugation reflects erythrocyte deformation in the pellet. The degree of erythrocyte deformation depends on the duration of centrifugation and the magnitude of centripetal acceleration.

Erythrocyte deformability and disease
Trends in Biochemical Sciences, 1982Abstract For human erythrocytes to endure their continual passage through the circulation for 120 days, they must remain deformable and flexible. Here we discuss the factors which may be responsible for premature cell death in some diseases.

Deformation of erythrocytes by trypanosomes
Experimental Cell Research, 1965The movements of Trypanosoma brucei are briefly described. The deformation of mouse erythrocytes by this organism is illustrated and the magnitude of the deforming force calculated.

Erythrocytes deformability and diabetes
Clinical Hemorheology and Microcirculation, 1983A large scale study of the erythrocyte deformability in diabetes is presented. The initial filtration flow rate method is used on diluted (white blood cells reduced) RBC suspensions. The rigidity index thus obtained, IR, is largely insensitive to the filter plugging.

Erythrocyte deformability and erythrocyte aggregation in preeclampsia.
Clinical hemorheology and microcirculation, 2001One of the features of preeclampsia is impaired blood rheology due to altered erythrocyte aggregation and erythrocyte deformability. We investigated these two parameters which affect the viscosity of blood, along with serum and intraerythrocytic magnesium concentrations, immunoglobulin titres and fibrinogen concentration in 12 preeclamptic women ...

Physico-chemical factors of erythrocyte deformability
Biorheology, 1985The aim of this study is to assess the role of different physicochemical factors on the deformability measurements by using the initial filtration flow rate method, and to differentiate between the membrane or internal origin of some rigidity changes. The deformability is maximum for the physiological pH value and it decreases sharply for hypotonic and

Reduced Erythrocytic Deformability in Megaloblastic Anemia
American Journal of Clinical Pathology, 1976Ten patients with megaloblastic anemia had erythrocytes with reduced deformability. The mean half-life for erythrocyte filtration was 9.89 minutes in these patients, compared with 5,20 minutes in controls. The half-life was inversely related to the hemoglobin concentration. After adequate vitamin replacement therapy filtrability improved significantly.

Erythrocyte Deformation in Human Muscular Dystrophy
Science, 1974Erythrocytes from patients with congenital muscular dystrophy exhibit dramatic surface deformation when observed with a scanning electron microscope. A similar alteration, but one affecting a smaller proportion of cells, occurs in the case of female carriers of the sex-linked Duchenne dystrophic condition.

Microscopic investigation of erythrocyte deformation dynamics
Biorheology: The Official Journal of the International Society of Biorheology, 2006The understanding of erythrocyte deformation under conditions of high shear stress and short exposure time is central to the study of hemorheology and hemolysis within prosthetic blood contacting devices. A combined computational and experimental microscopic study was conducted to investigate the erythrocyte deformation and its relation to transient ...
