Effect of lanthanum on red blood cell deformability

Biorheology: The Official Journal of the International Society of Biorheology, 2007
Prior reports describing the effects of lanthanum (La 3+ ) on red blood cells (RBC) have focused on the effects of this lanthanide on cell fusion or on membrane characteristics (e.g., ion movement across membrane, membrane protein aggregation); the present study explores its rheological and ...

Abnormal Blood Flow and Red Blood Cell Deformability in Severe Malaria

Parasitology Today, 2000
Obstruction of the microcirculation plays a central role in the pathophysiology of severe malaria. Here, Arjen Dondorp and colleagues describe the various contributors to impaired microcirculatory flow in falciparum malaria: sequestration, rosetting and ...

Red Blood Cell Deformability in Renal Failure

Nephron, 2008
Red blood cell deformability was measured in 74 cases of renal failure and diabetic nephropathy by means of a modified nuclepore membrane filter method. Low red blood cell deformability was observed in a certain proportion of the patients. In cases of renal failure only weak correlation was found between reduced red blood cell deformability and BUN as ...

Effect of pH on red blood cell deformability

Pflügers Archiv - European Journal of Physiology, 2000
The effect of pH on the red blood cell (RBC) deformability, which is a consequence of a change of cell membrane elastic properties is studied experimentally. With the intention to reduce the effects on deformability of cell geometry and cytoplasmic viscosity, we measured the deformability of the cells with the same volume at various pH of cell ...

Deformability of isolated red blood cell membranes

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1982
We have used a laser diffraction method (ektacytometry) to directly measure the membrane component of red cell deformability, without contributions from either cell geometry or internal viscosity. This technique was validated by subjecting resealed erythrocyte ghosts to manipulations previously shown to increase the membrane shear modulus.

Analysis of Red Blood Cell Deformation in a Microfluidic Device

ASME 2010 First Global Congress on NanoEngineering for Medicine and Biology, 2010
In this work, a microfluidics system to investigate the flow behaviour of red blood cells (RBCs) in a microcirculation-mimicking network of PDMS microchannels with thickness comparable to cell size is presented.

Hemoglobin Binding to the Red Blood Cell (RBC) Membrane Is Associated with Decreased Cell Deformability

International Journal of Molecular Sciences
The deformability of red blood cells (RBCs), expressing their ability to change their shape as a function of flow-induced shear stress, allows them to optimize oxygen delivery to the tissues and minimize their resistance to flow, especially in ...

Unit-to-unit variability in the deformability of red blood cells

Transfusion and Apheresis Science, 2020
In blood banking practice, the storage duration is used as the primary criterion for inventory management, and usually, the packed red blood cells (PRBC) units are supplied primarily according to first-in-first-out (FIFO) principle. However, the actual functionality of individual PRBC units is mostly ignored.

Influence of contrast media on red blood cell deformability

Clinical Hemorheology and Microcirculation, 2008
Iodinated contrast media (CM) are widely used in diagnostic imaging and therapeutic interventional procedures of everyday clinical practice and are associated with multiple hemodynamic and hemorheological effects. The purpose of our work was to investigate the red blood cell (RBC) rheological properties after in vivo administration of low-osmolar or ...

Red Blood Cells and Their Deformability

1981
In the previous chapter we studied the flow properties of blood. In this chapter we turn our attention to the red blood cells. Red blood cells are the gas exchange units of animals. They deliver oxygen to the tissues of all organs, exchange with CO2, and return to the lung to unload CO2 and soak up O2 again.
