Application of the "two-slit" photometric technique to the measurement of microvascular volumetric flow rates.
Abstract In vitro studies of red cell suspensions flowing through glass tubes were performed to provide additional details on the empirical relationship between red cell velocity measured by the… Expand

The goal of elucidating the biophysical and physiological basis of pressure–flow relations in the microcirculation has been a recurring theme since the first observations of capillary blood flow in… Expand
Leukocyte-endothelium adhesion: microhemodynamics in mesentery of the cat.
The effects of leukocyte-endothelium adhesion on microhemodynamics were studied in cat mesentery under control conditions and following tissue suffusion with the chemotactic agent… Expand
Leukocyte margination and deformation in mesenteric venules of rat.
White blood cell (WBC) margination and rolling were studied in venules (20-60 microns in diameter) in rat mesentery to examine the relationship between WBC rolling velocity (Vwbc), flux (Fwbc,… Expand
Composition of the endothelial glycocalyx and its relation to its thickness and diffusion of small solutes.
The endothelial glycocalyx is well endowed with the glycosaminoglycans (GAGs) heparan sulfate, chondroitin sulfate and hyaluronan. The current studies aimed to assess the relative contributions of… Expand

We study the mechanics of WBC–EC adhesion in shear flow using a two-dimensional model of an elastic ring adhered to an incompressible fluid as the cell interior. Expand
Inflammation- and ischemia-induced shedding of venular glycocalyx.
Alterations in the composition of the glycocalyx of venular endothelium in postcapillary venules (rat mesentery) were explored in models of inflammation and ischemia-reperfusion injury. Lectins were… Expand
Capillary recruitment in response to tissue hypoxia and its dependence on red blood cell deformability.
The effect of reduced red blood cell (RBC) deformability on microvessel recruitment attendant to a reduction in tissue PO2 was studied in rat cremaster muscle using indicator-dilution techniques.… Expand
In vivo measurements of "apparent viscosity" and microvessel hematocrit in the mesentery of the cat.
Abstract The arteriovenous (A-V) distribution of microvessel hematocrit (Hmicro) was determined throughout successive microvascular divisions in cat mesentery from in vivo measurements of optical… Expand
Microvascular hemodynamics during systemic hemodilution and hemoconcentration.
Measurements of intravascular pressure, red blood cell (RBC) velocity, and microvessel hematocrit (Hctmicro) were made in arterioles and venules of the cat mesenteric microvasculature during systemic… Expand
