Detecting Swelling States of Red Blood Cells by “Cell–Fluid Coupling Spectroscopy”
نویسندگان
چکیده
Red blood cells are "shaken" with a holographic optical tweezer array. The flow generated around cells due to the periodic optical forcing is measured with an optically trapped "detector" particle located in the cell vicinity. A signal-processing model that describes the cell's physical properties as an analog filter illustrates how cells can be distinguished from each other.

A Biomechanical Approach for the Study of Deformation of Red Cells in Narrow Capillaries
This model focuses on the behavior of capillary-tissue fluid exchange system when the diameter of the capillary is less than that of red cell. In vivo and in vitro observations indicate that the width of the gap between the red cell and the vessel wall is generally small compared to the radius of the capillary for a single file flow of red cell in narrow vessel, particularly if the vessel diame...

A 68-year-old male, known case of abdominal aortic dissection and recent aortic stent insertion, presented with gross hematuria. The urologists suspected aoro-ureteric fistula and performed open surgery (ureterolysis). Tc-99m labeled red blood cell (99mTc-RBC) scintigraphy was ordered to confirm the diagnosis and localize the possible aorto-ureteric fisula, Considering sustained gros...
متن کاملMathematical Analysis of MHD Flow of Blood in Very Narrow Capillaries (RESEARCH NOTE)
A mathematical model for blood flow in narrow capillaries under the effect of transverse magnetic field has been investigated. It is assumed that there is a lubricating layer between red blood cells and tube wall. The transient flow of the fit red blood cell surrounded by plasma annulus in the narrow capillary is considered. The analysis of fluid flow between red cell and tube wall, when the ce...
