    Hindcast of oil-spill pollution during the Lebanon crisis in the Eastern Mediterranean, July–August 2006 (2011)
    Elsevier
    Details
    Publication Date: 2017-04-04
    Description: MOON (Mediterranean Operational Oceanography Network http://www.moon-oceanforecasting.eu) pro- vides near-real-time information on oil-spill detection (ocean color and SAR) and predictions [ocean fore- casts (MFS and CYCOFOS) and oil-spill predictions (MEDSLIK)]. We employ this system to study the Lebanese oil-pollution crisis in summer 2006 and thus to assist regional and local decision makers in Europe, regionally and locally. The MEDSLIK oil-spill predictions obtained using CYCOFOS high-resolution ocean fields are compared with those obtained using lower-resolution MFS hydrodynamics, and both are validated against satellite observations. The predicted beached oil distributions along the Lebanese and Syrian coasts are compared with in situ observations. The oil-spill predictions are able to simulate the northward movement of the oil spill, with the CYCO- FOS predictions being in better agreement with satellite observations. Among the free MEDSLIK param- eters tested in the sensitivity experiments, the drift factor appears to be the most relevant to improve the quality of the results.
    Description: The paper was produced using the INGV MFS forecasting-sys- tem product and the OC-UCY CYCOFOS forecasting-system prod- ucts. The MODIS satellite data products were processed at the GOS-CNR-ISAC Rome laboratory using the SeaDAS software devel- oped by NASA GSFC, Greenbelt, Maryland, the HDFLook software developed by The Laboratoire d’Optique Atmosphérique, Univer- sity of Lille, France, and the MS2GT tool box developed by the Uni- versity of Colorado. Procedures for oil-spill detection were developed in the ENVI environment. Processed ENVISAT-ASAR data were made available by Telespazio and JRC. Part of this work was carried out with the support of the PRIMI project (ASI Contract No. I/094/06/0) financed by the Italian Space Agency (ASI).

    SigFuge: single gene clustering of RNA-seq reveals differential isoform usage among cancer samples (2014)
    Oxford University Press
    Details
    Publication Date: 2014-08-15
    Description: High-throughput sequencing technologies, including RNA-seq, have made it possible to move beyond gene expression analysis to study transcriptional events including alternative splicing and gene fusions. Furthermore, recent studies in cancer have suggested the importance of identifying transcriptionally altered loci as biomarkers for improved prognosis and therapy. While many statistical methods have been proposed for identifying novel transcriptional events with RNA-seq, nearly all rely on contrasting known classes of samples, such as tumor and normal. Few tools exist for the unsupervised discovery of such events without class labels. In this paper, we present SigFuge for identifying genomic loci exhibiting differential transcription patterns across many RNA-seq samples. SigFuge combines clustering with hypothesis testing to identify genes exhibiting alternative splicing, or differences in isoform expression. We apply SigFuge to RNA-seq cohorts of 177 lung and 279 head and neck squamous cell carcinoma samples from the Cancer Genome Atlas, and identify several cases of differential isoform usage including CDKN2A , a tumor suppressor gene known to be inactivated in a majority of lung squamous cell tumors. By not restricting attention to known sample stratifications, SigFuge offers a novel approach to unsupervised screening of genetic loci across RNA-seq cohorts. SigFuge is available as an R package through Bioconductor.

    A patient with acute pancreatitis and unusual vermiform stools (2014)
    BMJ Publishing Group
    In: Gut
    Details
    Publication Date: 2014-02-05
    Description: Case A 66-year-old woman was admitted with severe pancreatitis of unknown aetiology. Medical history disclosed insulin-dependent diabetes. She was treated conservatively with fluid and electrolyte correction. The patient was haemodynamically stable throughout the disease course. On day 4 she developed a paralytic ileus. Parenteral nutrition was initiated. Gradually, the ileus resolved. Enteral feeding was resumed on day 13 via a nasojejunal feeding tube. Over the following days, the patient developed watery diarrhoea. PCR and cultures failed to demonstrate a microbial cause. Suddenly, at day 21, the patient excreted per anus a 49 cm long vermiform soft strand ( figure 1 ). Question What is your diagnosis? See page 524 for answer Answer From question on page 493 Macroscopically, the excreted strand had a central lumen ( figure 2 ). Histological examination showed a completely necrotic, full-thickness colonic cast. All layers of the bowel wall, including...
