In 1996, Duke Children's Hospital was in serious trouble. Its $11 million annual operating loss had forced administrators to make cutbacks. As a result, some caregivers felt that the quality of care had deteriorated. Parents' complaints were on the rise. Frustrated staff members were quitting. In this article, Jon Meliones, DCH's chief medical director, candidly describes how his debt-ridden ho...
متن کاملClostridial iron-sulphur proteins.
Iron-sulfur proteins are ubiquitous catalysts of a wide range of biological reactions, and are particularly abundant in clostridia which lack the ability to synthesize hemes. The development of research on these metalloproteins has therefore been strongly associated with biochemical investigations of clostridial metabolism. Major breakthroughs in the field, from the first isolation of an iron-s...
متن کاملSulphur Dioxide Exposure
Bronchoalveolar lavage (BAL) which has not previously been used in investigating the effect of sulphur dioxide (SO2) on the human lung was performed on 12 subjects before and after controlled chamber exposure with SO2 for 20 minutes. BAL fluid 24 hours after exposure with 10 mg S02/m3 (4 ppm, 10 subjects) showed increased alveolar macrophage activity as judged by an increase in lysozyme positiv...

متن کاملSulphur isotope geochemistry
Ab&r&-Sulphur isotope abundances of thirty-nine specimens of seventeen meteorites are reported. The resultril show again the remarkable constancy of the sulphur isotope ratios for meteorites of all types. However, differences in the SBa/Sa* ratios of 0.4 %a would appear to be significant. The Ssz/P4 ratio for meteorites is discussed as a possible base level from which fr~tion&tion in the earth’...
