Journal ArticleDOI
Metal-carbon fiber composite femoral stems in hip replacements: a randomized controlled parallel-group study with mean ten-year follow-up.
D. Bennett,Janet C. Hill,Janice Dennison,Stephen J. O'Brien,J.L. Mantel,Graham Isaac,David E. Beverland +6 more
TL;DR: The investigational SR71 implant provided increased proximal bone density and reduced distal bone density ten years postoperatively relative to preoperative levels, and the clinical outcomes were similar to those of an all-metal stem at the time of a ten-year follow-up.
Book ChapterDOI
Giant Pandas: Analysis of demographic and genetic trends for developing a captive breeding masterplan for the giant panda
Jonathan D. Ballou,Philip S. Miller,Zhong Xie,Rongping Wei,Hemin Zhang,Anju Zhang,Shiquiang Huang,Shan Sun,Victor A. David,Stephen J. O'Brien,Kathy Traylor-Holzer,Ulysses S. Seal,David E. Wildt +12 more
TL;DR: The International Studbook for the Giant Panda contains detailed life history information on 542 giant pandas that have lived in zoos around the world (Xie & Gipps, 2001) as discussed by the authors.
Journal ArticleDOI
PTCH1 expression at diagnosis predicts imatinib failure in chronic myeloid leukaemia patients in chronic phase
Juan M. Alonso-Dominguez,Jacob Grinfeld,Jacob Grinfeld,Mary Alikian,David Marin,David Marin,Alistair Reid,Alistair Reid,Mustafa Daghistani,Corinne Hedgley,Stephen J. O'Brien,Richard E. Clark,Jane F. Apperley,Jane F. Apperley,Letizia Foroni,Letizia Foroni,Gareth Gerrard +16 more
TL;DR: PTCH1 expression assay showed the adequate sensitivity, specificity and predictive values to predict for IF, and was the most significant predictor in the multivariate analysis compared with Sokal, age and EUTOS.
Journal ArticleDOI
Fatal meningitis due to Moraxella duplex: report of a case with Waterhouse-Friderichsen syndrome.
Journal ArticleDOI
Linkage mapping of the human CSF2 and IL3 genes
Elena I. Frolova,Gregory Dolganov,Ilya Mazo,Dmitzy V. Smirnov,Paul R. Copeland,Claudia Stewart,Stephen J. O'Brien,Michael Dean +7 more
TL;DR: Multipoint linkage analysis permits the placement of the region containing the IL3 and CSF2 structural genes on the recombination-genetic linkage map of chromosome 5q and thereby allows the role of these genes in leukemogenesis to be more critically examined.
