Refractive index maps and membrane dynamics of human red blood cells parasitized by Plasmodium falciparum
Parasitization by malaria-inducing Plasmodium falciparum leads to structural, biochemical, and mechanical modifications to the host red blood cells (RBCs). To study these modifications, weExpand

Measurement of red blood cell mechanics during morphological changes
The human red blood cell (RBC) membrane, a fluid lipid bilayer tethered to an elastic 2D spectrin network, provides the principal control of the cell’s morphology and mechanics. These properties, inExpand

High-resolution three-dimensional imaging of red blood cells parasitized by Plasmodium falciparum and in situ hemozoin crystals using optical diffraction tomography
Abstract. We present high-resolution optical tomographic images of human red blood cells (RBC) parasitized by malaria-inducing Plasmodium falciparum (Pf)-RBCs. Three-dimensional (3-D) refractiveExpand

Occurrence of Extended-Spectrum β-Lactamases in Members of the Genus Shigella in the Republic of Korea
ABSTRACT A nationwide survey was carried out in Korea to assess the prevalence of Shigella strains producing extended-spectrum β-lactamases (ESBLs). From 1991 to 2002, 5,911 clinical strains wereExpand

Measurement Techniques for Red Blood Cell Deformability: Recent Advances
Human red blood cells (RBCs) or erythrocytes have remarkable deformability. Upon external forces, RBCs undergo large mechanical deformation without rupture, and they restore to original shapes whenExpand

Measurement of the nonlinear elasticity of red blood cell membranes.
The membranes of human red blood cells (RBCs) are a composite of a fluid lipid bilayer and a triangular network of semiflexible filaments (spectrin). We perform cellular microrheology using theExpand

Light scattering of human red blood cells during metabolic remodeling of the membrane.
We present the light scattering properties of individual human red blood cells (RBCs). We show that both the RBC static and dynamic scattering signals are altered by adenosine 5'-triphosphateExpand
