- Comparative analysis of multiple genomes in a phylogenetic framework dramatically improves the precision and sensitivity of evolutionary inference, producing more robust results than single-genome analyses can provide. The genomes of 12 Drosophila species, ten of which are presented here for the first time (sechellia, simulans, yakuba, erecta, ananassae, persimilis, willistoni, mojavensis, virilis and grimshawi), illustrate how rates and patterns of sequence divergence across taxa can illuminate evolutionary processes on a genomic scale. These genome sequences augment the formidable genetic tools that have made Drosophila melanogaster a pre-eminent model for animal genetics, and will further catalyse fundamental research on mechanisms of development, cell biology, genetics, disease, neurobiology, behaviour, physiology and evolution. Despite remarkable similarities among these Drosophila species, we identified many putatively non-neutral changes in protein-coding genes, non-coding RNA genes, and cis-regulatory regions. These may prove to underlie differences in the ecology and behaviour of these diverse species.

- Here we report a high-quality draft genome sequence of the domestic dog (Canis familiaris), together with a dense map of single nucleotide polymorphisms (SNPs) across breeds. The dog is of particular interest because it provides important evolutionary information and because existing breeds show great phenotypic diversity for morphological, physiological and behavioural traits. We use sequence comparison with the primate and rodent lineages to shed light on the structure and evolution of genomes and genes. Notably, the majority of the most highly conserved non-coding sequences in mammalian genomes are clustered near a small subset of genes with important roles in development. Analysis of SNPs reveals long-range haplotypes across the entire dog genome, and defines the nature of genetic diversity within and across breeds. The current SNP map now makes it possible for genome-wide association studies to identify genes responsible for diseases and traits, with important consequences for human and companion animal health.

- AIMS: Both retroperitoneal pelvic packing and primary angioembolization are widely used to control haemorrhage related to pelvic fractures. It is still unknown which protocol is the safest. The primary aim of this study is to compare survival and complications of pelvic packing and angioembolization in massive haemorrhage related to pelvic fractures.METHODS: Patients with haemodynamically unstable pelvic fractures were quasi-randomized to either pelvic packing (PACK) or angiography (ANGIO) using the time of admission as separator. Physiological markers of haemorrhage, time to intervention, procedure/surgical time, transfusion requirements, complications and early mortality were recorded and analyzed.RESULTS: 29 patients were randomized to PACK and 27 patients to ANGIO. The Injury Severity Score (ISS) in the ANGIO group was lower than in the PACK group (43±7 vs 48±6) (p<0.01). The median time from admission to angiography for the ANGIO group was 102min (range 76-214), and longer than 77min (range 43-125) from admission to surgery for the PACK group (p<0.01). The procedure time for the ANGIO group was 84min (range 62-105); while the surgical time was 60min (range 41-92) for the PACK group (p<0.001). The ANGIO group received 6.4 units packed red blood cells (range 4-10) in the first 24h after angiography. The PACK group required 5.2 units (range 3-10) in the first 24h after leaving the operating theatre (p=0.124). 9 patients in the ANGIO group underwent pelvic packing for persistent bleeding. 6 patients in the PACK group required pelvic angiography after pelvic packing for ongoing hypotension following packing (p=0.353). 5 patients in the ANGIO group died (2 from exsanguination), while 4 in the PACK group died (none from exsanguination) (p=0.449). Complications occurred without differences in both groups.CONCLUSIONS: Compared with angioembolization, pelvic packing has shorter time to intervention and surgical time. Thus pelvic packing is the more rapid treatment of severe pelvic trauma than pelvic angioembolization. It is suitable for patients with haemodynamic instability at centers where the interventional radiology staff is not in-house at all times.REGISTRATION: ClinicalTrials.gov (NCT02535624) and ISRCTN registry (ISRCTN91713422).
