In previous studies, cystic fibrosis (CF) fibroblasts were demonstrated to be resistant to the cytotoxic effects of ouabain, dexamethasone, and the sex hormones, dihydrotestosterone, 17beta-estradiol, and progesterone. We now show that CF fibroblasts also exhibit greatly increased resistance to the cytotoxic effects of exogenous dibutyryl cyclic AMP (cAMP),(More)
We are developing a CdZnTe pixel detector with a custom low-noise analog VLSI readout for use in the High-Energy Focusing Telescope (HEFT) balloon experiment, as well as for future space astronomy applications. The goal of the program is to achieve good energy resolution (< 1 keV FWHM @ 60 keV) and low threshold in a sensor with ~500 μm pixels. We have(More)
