BACKGROUND Multiplex bead array assays permit simultaneous cytometric quantitation of multiple cytokines in solution by capturing these to spectrally distinct beads. Because several manufacturers offer reagents to quantitate the same cytokines on a single instrument, a comparison should be made to determine whether these kits yield similar data and whether(More)
OBJECTIVE To determine whether neutrophil depletion could eradicate intestinal bacterial translocation in bum-injured rats. DESIGN Prospective, randomized, controlled study. SETTING University research laboratory. SUBJECTS Adult male Sprague-Dawley rats. INTERVENTIONS The rats were intravenously administered a rabbit anti-rat neutrophil antibody(More)
CD146 is a well described homotypic adhesion molecule found on endothelial cells and a limited number of other cell types. In cells from the peripheral circulation, CD146 has also been reported to be on activated lymphocytes in vitro and in vivo. The function associated with CD146 expression on lymphoid cells is unknown and very little information is(More)
To define gene expression profiles that occur during the initial activation of human innate immunity, we administered intravenous endotoxin (n = 8) or saline (n = 4) to healthy subjects and hybridized RNA from blood mononuclear cells (0, 0.5, 6, 24, 168 h) or whole blood (0, 3, 6, 24, 168 h) to oligonucleotide probe arrays. The greatest change in(More)
The finding of angiogenic and vasculogenic cells in the peripheral circulation may have profound effects on the course of a variety of diseases ranging from cancer to cardiovascular disease. These cells are ascribed to be endothelial in nature and are generally referred to as circulating endothelial cells if mature or as endothelial progenitor cells if(More)
BACKGROUND In canine models, transfused older stored red blood cells (RBCs) hemolyze in vivo resulting in significantly increased intravascular cell-free hemoglobin (CFH) and non-transferrin-bound iron (NTBI). During canine bacterial pneumonia with septic shock, but not in controls, older stored RBCs were associated with significantly increased lung injury(More)
