- To understand the biology and evolution of ruminants, the cattle genome was sequenced to about sevenfold coverage. The cattle genome contains a minimum of 22,000 genes, with a core set of 14,345 orthologs shared among seven mammalian species of which 1217 are absent or undetected in noneutherian (marsupial or monotreme) genomes. Cattle-specific evolutionary breakpoint regions in chromosomes have a higher density of segmental duplications, enrichment of repetitive elements, and species-specific variations in genes associated with lactation and immune responsiveness. Genes involved in metabolism are generally highly conserved, although five metabolic genes are deleted or extensively diverged from their human orthologs. The cattle genome sequence thus provides a resource for understanding mammalian evolution and accelerating livestock genetic improvement for milk and meat production.

- We report the sequence and analysis of the 814-megabase genome of the sea urchin Strongylocentrotus purpuratus, a model for developmental and systems biology. The sequencing strategy combined whole-genome shotgun and bacterial artificial chromosome (BAC) sequences. This use of BAC clones, aided by a pooling strategy, overcame difficulties associated with high heterozygosity of the genome. The genome encodes about 23,300 genes, including many previously thought to be vertebrate innovations or known only outside the deuterostomes. This echinoderm genome provides an evolutionary outgroup for the chordates and yields insights into the evolution of deuterostomes.

- Schizophrenia is a severe mental disorder with a lifetime risk of about 1%, characterized by hallucinations, delusions and cognitive deficits, with heritability estimated at up to 80%(1,2). We performed a genome-wide association study of 3,322 European individuals with schizophrenia and 3,587 controls. Here we show, using two analytic approaches, the extent to which common genetic variation underlies the risk of schizophrenia. First, we implicate the major histocompatibility complex. Second, we provide molecular genetic evidence for a substantial polygenic component to the risk of schizophrenia involving thousands of common alleles of very small effect. We show that this component also contributes to the risk of bipolar disorder, but not to several non-psychiatric diseases.

- OBJECTIVES: The true incidence of symptomatic deep venous thrombosis (DVT) and pulmonary embolism (PE) in patients undergoing laparoscopic radical prostatectomy is unknown. Our aim was to determine the incidence of symptomatic DVT and PE and the risk factors for these complications. METHODS: Fourteen surgeons from 13 referral institutions from both Europe and the United States provided retrospective data for all 5951 patients treated with laparoscopic radical prostatectomy (LRP), with or without robotic assistance, since the start of their institution's experience. Symptomatic DVT and PE within 90 d of surgery were regarded as venous thromboembolism (VTE). DVT was diagnosed mostly by Doppler ultrasound or contrast venography and PE by lung ventilation/perfusion scan or chest computed tomography or both. Statistical analysis included evaluation of incidence of symptomatic DVT and PE and risk factors as determined by exact methods and logistic regression. RESULTS: Of 5951 patients in the study, 31 developed symptomatic VTE (0.5%; 95% confidence interval [CI], 0.4%, 0.7%). Among patients with an event, 22 (71%) had DVT only, 4 had PE without identified DVT, and 5 had both. Two patients died of PE. Prior DVT (odds ratio [OR]=13.5; 95%CI, 1.4, 61.3), current tobacco smoking (OR=2.8; 95%CI, 1.0, 7.3), larger prostate volume (OR=1.18; 95%CI, 1.09, 1.28), patient re-exploration (OR=20.6; 95%CI, 6.6, 54.0), longer operative time (OR=1.05; 95%CI, 1.02, 1.09), and longer hospital stay (OR=1.05; 95%CI, 1.01, 1.09) were associated with VTE in univariate analysis. Neoadjuvant therapy, body mass index, surgical experience, surgical approach, pathologic stage, perioperative transfusion, and heparin administration were not significant predictors. CONCLUSIONS: The incidence of symptomatic VTE after LRP is low. These data do not support the administration of prophylactic heparin to all patients undergoing LRP, especially those without risk factors for VTE.
