RED BLOOD CELL DEFORMABILITY AND PHYSICAL ACTIVITY [PDF]

Journal of Applied Sports Sciences, 2022
Physical exertion and sport cause changes of different nature and degree (positive or negative, strong, weak, moderate) in blood and blood cells’ biomechanical and fluid properties.

Exercise-induced blood lactate increase does not change red blood cell deformability in cyclists. [PDF]

PLoS ONE, 2013
BACKGROUND: The effect of exercise-induced lactate production on red blood cell deformability and other blood rheological changes is controversial, given heavy-exercise induces biochemical processes (e.g., oxidative stress) known to perturb haemorheology.

THE SPRING VARIATION IN TWO DIMENSIONAL MODELING OF RED BLOOD CELL DEFORMABILITY BASED ON GRANULAR

Spektra: Jurnal Fisika dan Aplikasinya, 2019
The red blood cell membrane has a complex structure and high deformability. Simulation of that complex red blood cell membrane can simpler use granular-based modeling. Red blood cell is modeled consisting of 50 granular particles connected by springs. An

Effect of Magnesium on Red Blood Cell Deformability in Pregnancy

Hypertension in Pregnancy, 2005
Red blood cell (RBC) deformability is an important factor in determining movement of red blood cells through the microcirculation. In preeclampsia and some cases of intrauterine growth restriction (IUGR), RBC deformability and microcirculation are reduced. Magnesium is administered to reduce the risk of seizures.

Monitoring micro-rheological and multi-organ microcirculatory changes in abdominal sepsis in rats – a new approach to analyzing microcirculatory videos [PDF]

Frontiers in Physiology
BackgroundThe hemorheological and microcirculatory aspects of the pathophysiology of sepsis are partially understood and are often controversial in terms of the dynamics, extent, and correlation of parameters.

Quantifying the deformability of malaria-infected red blood cells using deep learning trained on synthetic cells

iScience, 2023
Summary: Several hematologic diseases, including malaria, diabetes, and sickle cell anemia, result in a reduced red blood cell deformability. This deformability can be measured using a microfluidic device with channels of varying width.

Reversibility of red blood cell deformation [PDF]

Physical Review E, 2012
The ability of cells to undergo reversible shape changes is often crucial to their survival. For Red Blood Cells (RBCs), irreversible alteration of the cell shape and flexibility often causes anemia. Here we show theoretically that RBCs may react irreversibly to mechanical perturbations because of tensile stress in their cytoskeleton.
