The interior surface is heparin-coated and there is no purge system. We implanted the device into six sheep to ascertain in-vivo haemodynamic(More)
Hypercarbia is a common complication of respiratory failure, and the technique of "permissive hypercapnia" is used to ventilate individuals with increased peak airway pressures on mechanical ventilators, resulting in elevated arterial PCO2. We studied the effects of hypercarbia on cultured bovine aortic and main pulmonary artery endothelial cell surface(More)
Time-lapse cinematography was used to investigate the movement of confronting populations of human mammary epithelium and stromal cells (fibroblasts). Epithelial cell islands from fibroadenomas and from normal lacteal secretions completely excluded the fibroblasts, and individual cell territories were maintained even in dense cultures. Electron microscopy(More)
