On the Move: Constructing, Rethinking, Narrating Identities

Social, cultural, political, technological and economic changes, such as globalization, migratory processes and cross-border population mobility, are key forces of transformation which have affected the notions of \u201chome\u201d, \u201cfamily\u201d and \u201cSelf\u201d. Identities are \u201con the move\u201d: they move across space and time, interact and undergo transformation. Identities are also discursively (re)produced, transformed, and destructed. This essay introduces the collection and its contents, putting the notion of identity - approached from different angles - into a unifying perspective

Use of coagulant spray glue (Glubran 2) for aerostatic purposes in pulmonary parenchyma resections in pigs: a preliminary study

BACKGROUND: The aim of our study was to test the aerostatic validity of a cyan-acrylic glue (Glubran 2), applied by means of a spray catheter, on an experimental pig model. MATERIALS AND METHODS: 15 young pigs were divided into three study groups of 5 based on surgical techniques: (1) atypical pulmonary resection with mechanical suturing and reinforcement with continuous suturing; (2) resection of the pulmonary parenchyma with a cold scalpel, followed by local application of Glubran 2; (3) atypical pulmonary resection with mechanical suturing followed by application of Glubran 2. RESULTS: The mean aerostasis time was calculated at 3.5 +/- 1.26 s. The histopathological analysis did not show any particular differences when comparing the effects of the treatments carried out with Glubran 2 spray glue and the standard treatments. No statistically significant differences were recorded in the short- and medium-term survival of pigs treated with Glubran 2 compared with the respective control groups. CONCLUSIONS: The application of Glubran 2 spray on wounds caused by pulmonary resections in pigs proved to have a rapid and effective influence for the purposes of aerostasis without significant differences in air losses and survivals

Experimental evidence for bounds on quantum correlations

We implemented the experiment proposed by Cabello [arXiv:quant-ph/0309172] to test the bounds of quantum correlation. As expected from the theory we found that, for certain choices of local observables, Cirel'son's bound of the Clauser-Horne-Shimony-Holt inequality ($2\sqrt{2}$) is not reached by any quantum states.Comment: RevTex style, 4 pages, 4 figures, to appear on PRL with minor revisio

Results of low energy background measurements with the Liquid Scintillation Detector (LSD) of the Mont Blanc Laboratory

The 90 tons liquid scintillation detector (LSD) is fully running since October 1984, at a depth of 5,200 hg/sq cm of standard rock underground. The main goal is to search for neutrino bursts from collapsing stars. The experiment is very sensitive to detect low energy particles and has a very good signature to gamma-rays from (n,p) reaction which follows the upsilon e + p yields n + e sup + neutrino capture. The analysis of data is presented and the preliminary results on low energy measurements are discussed

Hyperspectral remote sensing for light pollution monitoring

industries. In this paper we introduce the results from a remote sensing campaign performed in September 2001 at night time. For the first time nocturnal light pollution was measured at high spatial and spectral resolution using two airborne hyperspectral sensors, namely the Multispectral Infrared and Visible Imaging Spectrometer (MIVIS) and the Visible InfraRed Scanner (VIRS-200). These imagers, generally employed for day-time Earth remote sensing, were flown over the Tuscany coast (Italy) on board of a Casa 212/200 airplane from an altitude of 1.5-2.0 km. We describe the experimental activities which preceded the remote sensing campaign, the optimization of sensor configuration, and the images as far acquired. The obtained results point out the novelty of the performed measurements and highlight the need to employ advanced remote sensing techniques as a spectroscopic tool for light pollution monitoring

Her2 signaling and breast cancer stem cells: The bridge behind her2-positive breast cancer aggressiveness and therapy refractoriness

HER2 overexpression/amplification occurs in 15–20% of breast cancers (BCs) and identifies a highly aggressive BC subtype. Recent clinical progress has increased the cure rates of limited-stage HER2-positive BC and significantly prolonged overall survival in patients with advanced disease; however, drug resistance and tumor recurrence remain major concerns. Therefore, there is an urgent need to increase knowledge regarding HER2 biology and implement available treatments. Cancer stem cells (CSCs) represent a subset of malignant cells capable of unlimited self-renewal and differentiation and are mainly considered to contribute to tumor onset, aggressiveness, metastasis, and treatment resistance. Seminal studies have highlighted the key role of altered HER2 signaling in the maintenance/enrichment of breast CSCs (BCSCs) and elucidated its bidirectional communication with stemness-related pathways, such as the Notch and Wingless/β-catenin cascades. d16HER2, a splice variant of full-length HER2 mRNA, has been identified as one of the most oncogenic HER2 isoform significantly implicated in tumorigenesis, epithelial-mesenchymal transition (EMT)/stemness and the response to targeted therapy. In addition, expression of a heterogeneous collection of HER2 truncated carboxy-terminal fragments (CTFs), collectively known as p95HER2, identifies a peculiar subgroup of HER2-positive BC with poor prognosis, with the p95HER2 variants being able to regulate CSC features. This review provides a comprehensive overview of the current evidence regarding HER2-/d16HER2-/p95HER2-positive BCSCs in the context of the signaling pathways governing their properties and describes the future prospects for targeting these components to achieve long-lasting tumor control
