The C family G-protein-coupled receptors contain members that sense amino acid and extracellular cations, of which calcium-sensing receptor (CASR) is the prototypic extracellular calcium-sensing receptor. Some cells, such as osteoblasts in bone, retain responsiveness to extracellular calcium in CASR-deficient mice, consistent with the existence of another(More)
Bcl-2 family members have long been known to control permeabilization of the mitochondrial membrane during apoptosis, but involvement of these proteins in lysosomal membrane permeabilization (LMP) was not considered until recently. The aim of this study was to investigate the mechanism underlying the release of lysosomal proteases to the cytosol seen during(More)
We studied post-mortem 9 nonsmokers' lungs and 9 smokers' lungs as well as 14 surgical smokers' lungs to examine the possible relationship of the number of alveolar attachments with airways inflammation and with lung function. Alveolar attachments are the alveolar walls radially attached to the small airways, and any discontinuity or rupture of these(More)
Parenteral tetracycline, one of the most commonly used agents for producing pleurodesis, is no longer available because of stricter regulations governing the manufacturing process. The objective of this project was to determine whether minocycline, a tetracycline derivative, is an effective sclerosant in an experimental model in rabbits. We also studied the(More)
Destruction of alveolar walls is considered by most observers to be the most important part in the definition of emphysema, yet it has never been precisely defined and quantitated. We therefore attempted to devise a reliable microscopic technique to quantitate alveolar destruction that would be both sensitive to disease and easy to perform. Using a(More)
Insufflated talc is probably the most effective agent for creating a pleurodesis both in the clinical situation and in animals. However, the insufflation of talc requires an invasive procedure such as thoracoscopy or thoracotomy. Recently, there have been reports that talc in a slurry was effective in the clinical situation. The objective of this project(More)
Bcl-2 protein family members function either to promote or inhibit programmed cell death. Bcl-2, typically an inhibitor of apoptosis, has also been demonstrated to have pro-apoptotic activity (Cheng, E. H., Kirsch, D. G., Clem, R. J., et al. (1997) Science 278, 1966-1968). The pro-apoptotic activity has been attributed to the cleavage of Bcl-2 by caspase-3,(More)
Three cases of adenocarcinoma of the lung manifesting as acute pericardial effusion with tamponade are presented and the medical literature concerning this unusual manifestation of extracardiac malignancy is reviewed. We have found 22 cases of carcinoma and 4 cases of sarcoma. Of the carcinomas, 14 of 19 (74%) with known primary are pulmonary and 13 of 18(More)
Diverticulosis of the bronchial wall was found in patients not only with, but also without, chronic obstructive lung disease; it appeared to start as submicroscopic depressions and dilatations of the ducts of the bronchial gland on the mucosal surface. Multiple depressions and dilatations fused to form a diverticulum which herniated between and through the(More)
