Increased mortality at low-volume orthotopic heart transplantation centers: should current standards change?
Annual center volume is an independent predictor of short-term mortality in OHT. These data support reevaluation of the current CMS volume cutoff for OHT, as high-volume centers achieve lower mortality.
Fungal gene expression patterns cannot generally be described by a single type of distribution (bimodal or Zipf's law). One hypothesis to explain this finding might be that gene expression in fungi is highly dynamic, and fine-tuned at the level of transcription not only for individual genes, but also at a global level.
