Journal ArticleDOI
Genetic Ancestry of the Extinct Javan and Bali Tigers
Hao-Ran Xue,Nobuyuki Yamaguchi,Carlos Driscoll,Yu Han,Gila Kahila Bar-Gal,Yan Zhuang,Ji H. Mazak,David W. Macdonald,Stephen J. O'Brien,Shu-Jin Luo +9 more
TL;DR: The close phylogenetic relationship among Sunda tiger subspecies suggests either recent colonization across the islands, or else a once continuous tiger population that had subsequently isolated into different island subspecies, and supports the hypothesis that the Sumatran tiger is the closest living relative to the extinct Javan and Bali tigers.
Journal ArticleDOI
The influence of immediate knee flexion on blood loss and other parameters following total knee replacement
R. J. Napier,D. Bennett,J. McConway,R. K. Wilson,A. M. Sykes,E. Doran,Stephen J. O'Brien,D. E. Beverland +7 more
TL;DR: Post-operative knee flexion may offer a simple and cost-effective way to reduce blood loss and transfusion requirements following total knee replacement.
Book ChapterDOI
Bacteria: Other Pathogenic Enterobacteriaceae – Enterobacter and Other Genera
TL;DR: The authors review the general characteristics and links to food contamination along with associated clinical signs of Enterobacteriaceae species and comment on current laboratory-based methodologies used for isolation, identification, and subtyping.
Journal Article
The promise of comparative genomics in mammals : Genome
Stephen J. O'Brien,Marilyn Menotti-Raymond,William J. Murphy,William G. Nash,Johannes Wienberg,Roscoe Stanyon,N. G. Copeland,Nancy A. Jenkins,James E. Womack,Jennifer A. Marshall Graves +9 more
TL;DR: Comparative genetic assessment expands the utility of dense genetic maps of human, mouse, and rat genomes in gene discovery, in functional genomics, and in tracking the evolutionary forces that sculpted the genome organization of modern mammalian species.
Journal ArticleDOI
Characterization of Staphylococcus aureus isolated from dairy animals in Ireland.
TL;DR: Staphylococcus aureus was isolated from bovine, ovine and caprine milk and milk filters from 78 dairy production holdings supplying the farmhouse cheese sector in Ireland, using standard culture methods to study the distribution of genes encoding staphylitiscal enterotoxins and toxic shock syndrome toxin.
