Eosinophils and neutrophils are closely related, terminally differentiated cells that in vitro undergo constitutive cell death by apoptosis. The onset of apoptosis in both cell types can be delayed by hemopoietins and inflammatory mediators. Although there have been a number of reports demonstrating that glucocorticoids (in particular dexamethasone)(More)
Phagocyte recognition, uptake, and nonphlogistic degradation of neutrophils and other leukocytes undergoing apoptosis promote the resolution of inflammation. This study assessed the effects of anti-inflammatory glucocorticoids on this leukocyte clearance mechanism. Pretreatment of "semimature" 5-day human monocyte-derived macrophages (M phi) for 24 h with(More)
Neutrophil apoptosis, determined after 20 h in culture using standard criteria and shedding of cell surface CD16 (Fc gamma RIII), is dramatically inhibited, in a concentration-dependent manner, by the cAMP analogs, dibutyryl-cAMP and 8-Br-cAMP, and the adenylyl cyclase activator, forskolin. Furthermore, the stable receptor-directed PGD2 mimetic, ZK 118.182,(More)

This study emerging from profound consideration of the basis of vectorcardiography reveals a new electric model of the heart, the starting point for a computer programme of which only the principle is described. Noting inadequacies of vectorcardiography linked to necessary but possibly excessive simplifications, the author suggests a solution based only on(More)
