Methods to Investigate the Deformability of RBC During Malaria

Frontiers in Physiology, 2020
Despite a 30% decline in mortality since 2000, malaria still affected 219 million subjects and caused 435,000 deaths in 2017. Red blood cells (RBC) host Plasmodium parasites that cause malaria, of which Plasmodium falciparum is the most pathogenic.

Red Blood Cell Oxidative Stress impairs oxygen delivery and induces Red Blood Cell Aging

Frontiers in Physiology, 2014
Red Blood Cells (RBCs) need to deform and squeeze through narrow capillaries. Thus, decreased deformability of RBCs contributes to the elimination of aged or damaged RBCs from the circulation.

Red Blood Cell Shape and Deformability in Patients With COVID-19 Acute Respiratory Distress Syndrome

Frontiers in Physiology, 2022
BackgroundAcute respiratory distress syndrome due to coronavirus disease 2019 (COVID-19) is associated with high mortality. Several studies have reported that the microcirculation responds adequately to hypoxia in COVID-19 patients by increasing oxygen ...

Shear Stress Ameliorates Superoxide Impairment to Erythrocyte Deformability With Concurrent Nitric Oxide Synthase Activation [PDF]

, 2019
The cellular deformability of red blood cells (RBC) is exceptional among mammalian cells and facilitates nutrient delivery throughout the microcirculation; however, this physical property is negatively impacted by oxidative stress.

The Effect of Alkyl Chain Number in Sucrose Surfactant on the Physical Properties of Quercetin-Loaded Deformable Nanoliposome and Its Effect on In Vitro Human Skin Penetration

Nanomaterials, 2018
Non-invasive skin penetration of a drug is increased by an edge activator, which enhances the nanoliposome deformability. The objective of this study was to investigate the role of the alkyl chain number of sucrose surfactants as an edge activator in ...

Application of Artificial Neural Network to the Prediction of Tensile Properties in High-Strength Low-Carbon Bainitic Steels

Metals, 2021
An artificial neural network (ANN) model was designed to predict the tensile properties in high-strength, low-carbon bainitic steels with a focus on the fraction of constituents such as PF (polygonal ferrite), AF (acicular ferrite), GB (granular bainite),

An On-Chip RBC Deformability Checker Significantly Improves Velocity-Deformation Correlation

Micromachines, 2016
An on-chip deformability checker is proposed to improve the velocity–deformation correlation for red blood cell (RBC) evaluation. RBC deformability has been found related to human diseases, and can be evaluated based on RBC velocity through a ...
