Red blood cell deformability in multiple myeloma
Clinical Hemorheology and Microcirculation, 2018The aim of this study was the evaluation of the erythrocyte deformability in multiple myeloma (MM). We enrolled 29 MM patients and we evaluated, on fasting venous blood, the erythrocyte deformability, expressed as elongation index, and examined using the diffractometric method.

Assessing red blood cell deformability from microscopy images using deep learning.
Lab on a Chip, 2021Red blood cells (RBCs) must be highly deformable to transit through the microvasculature to deliver oxygen to tissues. The loss of RBC deformability resulting from pathology, natural aging, or storage in blood bags can impede the proper function of these

Effect of pH on red blood cell deformability
Pflügers Archiv - European Journal of Physiology, 2016The 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 ...

Analyzing Red Blood Cell-Deformability Distributions
Blood Cells, Molecules, and Diseases, 2002Red blood cells (RBCs) must deform to pass the smallest capillaries of the microcirculation. Available techniques for measuring RBC deformability often provide an indication of the mean deformability. The latter may be decreased either by a slight overall deformability reduction or by the presence of a small fraction of rigid cells.

Deformation of Red Blood Cells in Capillaries
Science, 1969The shapes of red blood cells in capillary blood vessels are reinterpreted from observations of human red cells. The parachute or umbrella shape often observed is not an axisymmetric shape as formerly assumed, but is the basic biconcave disk shape of the red cell with the upstream end flattened by the pressure gradient.

Red Blood Cell Deformability in Sepsis
American Journal of Respiratory and Critical Care Medicine, 1998Abstract The microcirculatory disturbances in sepsis have prompted micropore bulk-filtration studies of red blood cell (RBC) mechanical behavior (i.e., deformability). However, these prior reports may not solely reflect RBC behavior because of possible white blood cell (WBC) occlusion of the filter pores.

Red blood cell deformability and the prostaglandins
Prostaglandins, 1973Abstract The effects of Prostaglandin E 1 and Prostaglandin E 2 on the deformability of the human red blood cell have been studied using the glass micropipette method. In the range of concentrations 10 −13 to 10 −5 M, neither PGE 1 nor PGE 2 alters the red cell deformability.

Elastic deformations of red blood cells
Journal of Biomechanics, 1977Abstract Large, elastic deformations of red blood cells are computed on the basis of an assumed model of the red blood cell membrane which includes the elasticity of the membrane under tensions in its own plane and the bending elasticity. The analysis is based on a variational principle implemented by a finite element method.

Red blood cell deformability and protein adsorption on red blood cell surface
American Journal of Physiology-Heart and Circulatory Physiology, 1984Effects of protein and NaCl concentrations in plasma on red blood cell (RBC) deformability were studied using fresh human blood and a 5-microns Nuclepore filtration test. The protein and salt concentrations were varied by diluting the plasma with saline and adding crystalline NaCl to the fluids, respectively.
