• C-4 sterol demethylation enzymes distinguish bacterial and eukaryotic sterol synthesis [Microbiology]

  Sterols are essential eukaryotic lipids that can be preserved as steroids in sedimentary rocks for billions of years. Because eukaryotes are the predominant modern day producers of these lipids, fossilized sterols are used as geological biomarkers for the presence of specific eukaryotes in ancient e more

• Tocilizumab for the treatment of severe steroid-refractory acute graft-versus-host disease of the lower gastrointestinal tract

  Steroid-refractory (SR) acute gastrointestinal (GI) graft-versus-host disease (GVHD) is associated with significant mortality in allogeneic hematopoietic cell transplantation recipients. We retrospectively evaluated the efficacy of tocilizumab for the treatment of SR biopsy-proven acute lower GI GVH more

• The window of improved neonatal respiratory compliance after rescue antenatal steroids

  To evaluate whether premature infants delivered ≤7 days after rescue antenatal steroid treatment (ideal treatment) have increased passive respiratory compliance compared to those delivered >7 days after treatment (remote treatment). Secondary analysis of a randomized trial of rescue antenatal steroi more
