We have previously shown [B. Illek, H. Fischer, G. F. Santos, J. H. Widdicombe, T. E. Machen, and W. W. Reenstra, Am. J. Physiol. 268 (Cell Physiol. 37): C886-C893, 1995] that genistein, a tyrosine kinase inhibitor, activates the cystic fibrosis transmembrane conductance regulator (CFTR) chloride channel in NIH/3T3 cells that have been stably transfected(More)
Recent studies have demonstrated that several compounds with diverse structures can activate wild-type cystic fibrosis transmembrane conductance regulator (CFTR) by non-receptor-mediated mechanisms. Some of these compounds have been shown to enhance cAMP-dependent activation of DeltaF508-CFTR. This study was undertaken to compare the mechanisms by which(More)
The microenvironment of cancer plays a very critical role in the survival, proliferation and drug resistance of solid tumors. Here, we report an interesting, acidic cancer microenvironment-mediated dissolution-induced preferential toxicity of ZnO nanocrystals (NCs) against cancer cells while leaving primary cells unaffected. Irrespective of the size-scale(More)
We have carried out perfusion studies on hydropenic and bicarbonate-loaded rats to provide direct in vivo observations on bicarbonate accumulation in the short loops of Henle. Analysis of early distal tubular fluid was made during bicarbonate-free saline perfusion from the end proximal to the early distal site, documenting accumulation of "new" bicarbonate.(More)
Studies have been carried out in awake chronically cannulated adrenalectomized rats subjected to steroid replacement protocols. Our objective was to determine the effects of mineralocorticoid or glucocorticoid or combined replacement on acid-base composition of the extracellular fluid compartment in response to an acute ammonium chloride acid load. We(More)
Statistical issues relating to data analysis of re-collection micropuncture experiments are presented. In the presence of significant animal-treatment interaction, namely, differential response of each animal at different levels of the treatment, the conventional paired or unpaired t testing would not be entirely appropriate. Accordingly, two analysis of(More)
To test the assumption that students who have completed other clerkships are likely to perform better in internal medicine, the authors undertook a prospective study of 160 senior students from two classes. Groups of students with little or no senior clerkship experience before their internal medicine clerkship were compared with groups of students who had(More)
