Structural variants of an agonist peptide-major histocompatibility complex (MHC) molecule ligand can show partial agonist and/or antagonist properties. A number of such altered ligands appear to act as pure antagonists. They lack any detectable ability to induce T cell effector function and have been described as unable to induce calcium transients and(More)

Although obliteration of the left ventricular (LV) cavity at end-systole is interpreted as indicative of intraoperative hypovolemia, this relation has not been demonstrated directly. METHODS We continuously monitored the LV(More)
Many previous investigators have utilized mechanical rubbing as a method for examining effects of epithelial removal. In the present study, we examined whether this procedure also affects mast cell integrity in the underlying lamina propria. We isolated bronchial rings from six ferrets, and we found that removal of epithelium by rubbing decreased the total(More)
