Journal ArticleDOI
Modifiable factors delaying early discharge following primary joint arthroplasty.
Richard J. Napier,David J. Spence,Owen J. Diamond,Stephen J. O'Brien,T. Walsh,David E. Beverland +5 more
TL;DR: This unit aims to develop improvement in social work provision, with a greater focus on pre-admission discharge planning to reduce the number of delayed discharges and ultimately reduce the cost burden of joint replacement surgery.
Journal ArticleDOI
The fishes of Genome 10K.
Giacomo Bernardi,Edward O. Wiley,Hicham Mansour,Michael R. Miller,Guillermo Ortí,David Haussler,Stephen J. O'Brien,Oliver A. Ryder,Byrappa Venkatesh +8 more
TL;DR: The Genome 10K project aims to sequence the genomes of 10,000 vertebrates, representing approximately one genome for each vertebrate genus, and an additional 100 fishes have been identified for sequencing in the next phase.
Journal ArticleDOI
Molecular Genetic Insights on Cheetah (Acinonyx jubatus) Ecology and Conservation in Namibia
Laurie Marker,Alison J. Pearks Wilkerson,Ronald J. Sarno,Janice S. Martenson,Christian Breitenmoser-Würsten,Stephen J. O'Brien,Warren E. Johnson +6 more
TL;DR: Parentage analyses confirmed several observations based on field studies and verified the successful integration and reproduction of several cheetahs following natural dispersal or translocation, suggesting this is a generally panmictic population.
Journal ArticleDOI
A tumor necrosis factor-α-inducible promoter variant of interferon-γ accelerates CD4+ t cell depletion in human immunodeficiency virus-1-infected individuals
Ping An,David Vlahov,Joseph B. Margolick,John P. Phair,Thomas R. O'Brien,James A. Lautenberger,Stephen J. O'Brien,Cheryl A. Winkler,Cheryl A. Winkler +8 more
TL;DR: A polymorphism, -179G/T, in the promoter of the interferon (IFN)-gamma gene (IFNG) confers differential tumor necrosis factor-alpha (TNF-alpha) inducibility to the IFNG promoter, suggesting that IFNG -179T is a risk factor for AIDS progression, as measured by CD4 cell count.
