From Polymers to Membranes: Elastic Properties of Red Blood Cells
Recently experiments have been conducted to investigate the behavior of live human red blood cells under optical forces generated using both linearly and circularly polarized light [1, 2]. These experiments have shown that a normal human RBC, which has a biconcave disk shape, approximately 8 μm in diameter, deforms into a folded shape upon being placed in an optical trap; the trapped RBC subseq...
متن کاملFusion of Human Red Blood Cell Membranes
The ability of the parainfluenza group of viruses to induce cell fusion with the production of polykaryocytes and heterokaryons of animal cells has been well documented (1, 2, 3, 4) . Much of the interest in cell fusion in recent years has centered on cell hybrids with nuclei of different species occupying the same cell . Such hybrid cells have proved useful for studies of nuclear-cytoplasmic r...
متن کاملHypoxic Vasodilation by Red Blood Cells
Red blood cells (RBCs) have been ascribed an essential role in matching blood flow to local metabolic demand during hypoxic vasodilation. The vasodilatory function of RBCs evidently relies on the allosteric properties of hemoglobin (Hb), which couple the conformation of Hb to tissue oxygen tension (PO2) and thereby provide a basis for the graded vasodilatory activity that is inversely proportio...
متن کاملSingle scattering by red blood cells.
A highly diluted suspension of red blood cells (hematocrit 0.01) was illuminated with an Ar or a dye laser in the wavelength range of 458-660 nm. The extinction and the angle-resolved intensity of scattered light were measured and compared with the predictions of Mie theory, the Rayleigh-Gans approximation, and the anomalous diffraction approximation. Furthermore, empirical phase functions were...
متن کاملLight scattering by multiple red blood cells.
The interaction of light with multiple red blood cells was systematically investigated by the finite-difference time-domain method (FDTD). The simulations showed that the lateral multiple scattering between red blood cells is very weak and that the polarization has an almost insignificant influence on the distribution of the scattered light. The numerical results of the FDTD method were compare...
