    Spatial Translations and Embodied Bilingualism: Defining the Migrant\u27s Experience from an Architectural Perspective

    As a bilingual writer and architect, my research is practice-based and multidisciplinary. In pulling together theories and practices about Space, Language and the Body, my aim is to develop a notion of Embodied Bilingualism. If the word ‘translate’ is to move something from one place to another, as architectural historian Robin Evans explains, then one needs to understand its pure and unconditional existence as a geometrical construct in the first place in order to fully appreciate the workings of linguistic translation. In this paper, language is considered as an embodied practice, which for the bilingual migrant leads to considerations about translatory motion not only of the body, but also of words. Using the contribution of Henri Poincare to the philosophy of geometry, we will see how the body’s very own capacity of movement contributes to the understanding of the movement of words

    <p>Abstract</p> <p>Background</p> <p>Comprehensive understanding of molecular mechanisms underlying viral infection is a major challenge towards the discovery of new antiviral drugs and susceptibility factors of human diseases. New advances in the field are expected from systems-level modelling and integration of the incessant torrent of high-throughput "-omics" data.</p> <p>Results</p> <p>Here, we describe the Human Infectome protein interaction Network, a novel systems virology model of a virtual virus-infected human cell concerning 110 viruses. This <it>in silico </it>model was applied to comprehensively explore the molecular relationships between viruses and their associated diseases. This was done by merging virus-host and host-host physical protein-protein interactomes with the set of genes essential for viral replication and involved in human genetic diseases. This systems-level approach provides strong evidence that viral proteomes target a wide range of functional and inter-connected modules of proteins as well as highly central and bridging proteins within the human interactome. The high centrality of targeted proteins was correlated to their essentiality for viruses' lifecycle, using functional genomic RNAi data. A stealth-attack of viruses on proteins bridging cellular functions was demonstrated by simulation of cellular network perturbations, a property that could be essential in the molecular aetiology of some human diseases. Networking the Human Infectome and Diseasome unravels the connectivity of viruses to a wide range of diseases and profiled molecular basis of Hepatitis C Virus-induced diseases as well as 38 new candidate genetic predisposition factors involved in type 1 <it>diabetes mellitus</it>.</p> <p>Conclusions</p> <p>The Human Infectome and Diseasome Networks described here provide a unique gateway towards the comprehensive modelling and analysis of the systems level properties associated to viral infection as well as candidate genes potentially involved in the molecular aetiology of human diseases.</p

    Epstein-Barr virus nuclear antigen 3A protein regulates CDKN2B transcription via interaction with MIZ-1

    The Epstein-Barr virus (EBV) nuclear antigen 3 family of protein is critical for the EBV-induced primary B-cell growth transformation process. Using a yeast two-hybrid screen we identified 22 novel cellular partners of the EBNA3s. Most importantly, among the newly identified partners, five are known to play direct and important roles in transcriptional regulation. Of these, the Myc-interacting zinc finger protein-1 (MIZ-1) is a transcription factor initially characterized as a binding partner of MYC. MIZ-1 activates the transcription of a number of target genes including the cell cycle inhibitor CDKN2B. Focusing on the EBNA3A/MIZ-1 interaction we demonstrate that binding occurs in EBV-infected cells expressing both proteins at endogenous physiological levels and that in the presence of EBNA3A, a significant fraction of MIZ-1 translocates from the cytoplasm to the nucleus. Moreover, we show that a trimeric complex composed of a MIZ-1 recognition DNA element, MIZ-1 and EBNA3A can be formed, and that interaction of MIZ-1 with nucleophosmin (NPM), one of its coactivator, is prevented by EBNA3A. Finally, we show that, in the presence of EBNA3A, expression of the MIZ-1 target gene, CDKN2B, is downregulated and repressive H3K27 marks are established on its promoter region suggesting that EBNA3A directly counteracts the growth inhibitory action of MIZ-1

    This article focuses on a few episodes in the life of Countess Adelaide del Vasto, regent of the county of Calabria and of Sicily, as recounted by her principal biographer Orderic Vitalis. In his chronicle, the Norman monk highlights the theme of poisoning by women in power.Cet article dĂ©crit quelques Ă©pisodes de la vie de la comtesse AdĂ©laĂŻde del Vasto, rĂ©gente de comtĂ© de Calabre et de Sicile, telle qu’elle nous a Ă©tĂ© transmise par son principal biographe, Orderic Vital.

    Event-Driven User-Centric Middleware for Energy Efficient Buildings and Public Spaces

    In this work, the design of an event-driven user-centric middleware for monitoring and managing energy consumption in public buildings and spaces is presented. The main purpose is to increase the energy efficiency, reducing consumption, in buildings and public spaces. To achieve this, the proposed service-oriented middleware has been designed to be event based, also exploiting the user behaviours patterns of the people who live and work into the building. Furthermore, it allows an easy integration of heterogeneous technologies in order to enable a hardware independent interoperability between them. Moreover, a Heating Ventilation and Air Conditioning (HVAC) control strategy has been developed and the whole infrastructure has been deployed in a real-world case study consisting of a historical building. Finally the results will be presented and discusse
