ALPPS Improves Resectability Compared with Conventional Two-stage Hepatectomy in Patients with Advanced Colorectal Liver Metastasis : Results from a Scandinavian Multicenter Randomized Controlled Trial (LIGRO Trial)

Objective: The aim of the study was to evaluate if associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) could increase resection rates (RRs) compared with two-stage hepatectomy (TSH) in a randomized controlled trial (RCT). Background: Radical liver metastasis resection offers the only chance of a cure for patients with metastatic colorectal cancer. Patients with colo

Geospatial data integration and visualisation using Linked Data

Geospatial data are increasingly available nowadays, and this leads to more analyses and visualisation of geospatial data from several sources. To enable this, we need homogenous data as well as proper integration methods. Geospatial data integration has been a longstanding research topic for decades, and this paper discusses the utilisation of Linked Data technology stack to alleviate the geospat

Risk Analysis and Management of IT Systems: Practice and Challenges

Risk analysis is important for safety-critical IT systems and services, both in public and private organizations. However, the actual practices and the challenges of risk analysis in these contexts have not been fully explored. This paper investigates the current practices of risk analysis by an interview-based investigation. This study investigates several factors of the risk analysis process, e.Risk analysis is important for safety-critical IT systems and services, both in public and private organizations.

Evolution of the Vertebrate Pax4/6 Class of Genes with Focus on Its Novel Member, the Pax10 Gene

Themembers of the paired box (Pax) family regulate key developmental pathways inmanymetazoans as tissue-specific transcription factors. Vertebrate genomes typically possess nine Pax genes (Pax1–9), which are derived from four proto-Pax genes in the vertebrate ancestor that were later expanded through the so-called two-round (2R) whole-genome duplication. A recent study proposed that pax6a genes of

Identification of tumor margins using diffuse reflectance spectroscopy with an extended-wavelength spectrum in a porcine model

OBJECTIVE: A novel extended-wavelength diffuse reflectance spectroscopy (EWDRS) technique is being developed for future clinical non-invasive tumor margin delineation. In this study, the ability of EWDRS to identify the margins of pigmented skin lesions in an in vivo pig model was evaluated.MATERIALS AND METHODS: Extended-wavelength diffuse reflectance spectroscopy recordings (350-1550 nm) were ma

Revisiting the Origin of the Vertebrate Hox14 by Including Its Relict Sarcopterygian Members

Bilaterian Hox genes play pivotal roles in the specification of positional identities along the anteroposterior axis. Particularly in vertebrates, their regulation is tightly coordinated by tandem arrays of genes [paralogy groups (PGs)] in four gene clusters (HoxA-D). Traditionally, the uninterrupted Hox cluster (Hox1-14) of the invertebrate chordate amphioxus was regarded as an archetype of theve

The origin of bmp16, a novel Bmp2/4 relative, retained in teleost fish genomes

Background: Whole genome sequences have allowed us to have an overview of the evolution of gene repertoires. The target of the present study, the TGFβ superfamily, contains many genes involved in vertebrate development, and provides an ideal system to explore the relationships between evolution of gene repertoires and that of developmental programs.Results: As a result of a bioinformatic survey of

Co-orthology of Pax4 and Pax6 to the fly eyeless gene: molecular phylogenetic, comparative genomic, and embryological analyses

The functional equivalence of Pax6/eyeless genes across distantly related animal phyla has been one of central findings on which evo-devo studies is based. In this study, we show that Pax4, in addition to Pax6, is a vertebrate ortholog of the fly eyeless gene (and its duplicate, twin of eyeless [toy] gene, unique to Insecta). Molecular phylogenetic trees published to date placed the Pax4 gene outs

The Imprinted NPAP1 Gene in the Prader–Willi Syndrome Region Belongs to a POM121-Related Family of Retrogenes

We have recently shown that the human Nuclear pore-associated protein (NPAP1)/C15orf2 gene encodes a nuclear pore-associated protein. This gene is one of several paternally expressed imprinted genes in the genomic region 15q11q13. Because the Prader–Willi syndrome is known to be caused by the loss of function of paternally expressed genes in 15q11q13, a phenotypic contribution of NPAP1 cannot be e

Saltatory Evolution of the Ectodermal Neural Cortex Gene Family at the Vertebrate Origin

The ectodermal neural cortex (ENC) gene family, whose members are implicated in neurogenesis, is part of the kelch repeat superfamily. To date, ENC genes have been identified only in osteichthyans, although other kelch repeat-containing genes are prevalent throughout bilaterians. The lack of elaborate molecular phylogenetic analysis with exhaustive taxon sampling has obscured the possible link of

The African coelacanth genome provides insights into tetrapod evolution

The discovery of a living coelacanth specimen in 1938 was remarkable, as this lineage of lobe-finned fish was thought to have become extinct 70 million years ago. The modern coelacanth looks remarkably similar to many of its ancient relatives, and its evolutionary proximity to our own fish ancestors provides a glimpse of the fish that first walked on land. Here we report the genome sequence of the

Habitat filtering determines the functional niche occupancy of plant communities worldwide

How the patterns of niche occupancy vary from species-poor to species-rich communities is a fundamental question in ecology that has a central bearing on the processes that drive patterns of biodiversity. As species richness increases, habitat filtering should constrain the expansion of total niche volume, while limiting similarity should restrict the degree of niche overlap between species. Here,

Factors affecting outcomes following pelvic exenteration for locally recurrent rectal cancer

Background: Pelvic exenteration for locally recurrent rectal cancer (LRRC) is associated with variable outcomes, with the majority of data from single-centre series. This study analysed data from an international collaboration to determine robust parameters that could inform clinical decision-making. Methods: Anonymized data on patients who had pelvic exenteration for LRRC between 2004 and 2014 we

Time-resolved inner-shell photoelectron spectroscopy : From a bound molecule to an isolated atom

Due to its element and site specificity, inner-shell photoelectron spectroscopy is a widely used technique to probe the chemical structure of matter. Here, we show that time-resolved inner-shell photoelectron spectroscopy can be employed to observe ultrafast chemical reactions and the electronic response to the nuclear motion with high sensitivity. The ultraviolet dissociation of iodomethane (CH3I
