Characterizing Erythrocyte Motions In Flowing Blood, Markos Leggas
Characterizing Erythrocyte Motions In Flowing Blood, Markos Leggas
Theses and Dissertations (ETD)
Characterizing the probabilistic motions of cells is a prerequisite for the development of a general model of transport and surface deposition of white cells and platelets (WBC/P). These phenomena differ greatly when red blood cells (RBC) are present at normal levels, but follow convective diffusion in dilute suspensions. A critical need is to understand and characterize dispersion and diffusion as they apply to red cells in suspension flow. The dispersive motions of
0.5-micrometer beads and fluorescently labeled human RBC flowing in dilute (0.003%) and concentrated (25%) RBC suspensions, respectively, were characterized using fluorescence videomicroscopy methods, and times for individual tracer …
Late Effects Of Ionizing Radiation On Normal Microvascular Networks, Vinh Nguyen
Late Effects Of Ionizing Radiation On Normal Microvascular Networks, Vinh Nguyen
Theses and Dissertations (ETD)
Therapeutic doses of ionizing radiation result in changes in the structure and function of microvascular networks in normal tissue. Previously, we reported on the early effects of ionizing radiation on microvascular networks at 3, 7, and 30 days post-irradiation [1-3]. Data from the early time points suggested that ionizing radiation significantly alters the structure and function of microvascular networks and interferes with the normal processes of vessel maturation. Here, we
present our findings on the late effects of ionizing radiation on normal tissue microvasculature at 60, 120, and 180 days post-irradiation. The cremaster muscle of Golden Syrian hamster was locally …
