Early intestinal perforation secondary to congenital mesenteric defects

2016

Abstract Gastrointestinal perforation (GIP) in preterm neonates may be idiopathic, due to necrotizing enterocolitis (NEC), or mechanical obstruction. The predominant cause of GIP in the neonatal period is NEC. Differential diagnosis with congenital malformations, including mesenteric defects leading to internal hernias, is mandatory if the onset is early. We describe two newborns with trans-mesenteric herniation resulting in GIP, and we discuss the presence of possible additional risk factors such as prematurity and predisposing vascular disruption in connective tissue disorders (Ehlers-Danlos syndrome), twinning, and use of assisted reproductive technologies. These cases prompted us to rev…

Evolving Conceptualisations of Internationalism in the UK Parliament : Collocation Analyses from the League to Brexit

2020

This chapter explores a historical distant reading strategy of British Parliamentary discourse. It uses historical collocation analyses of ‘internationalism’ and the ‘international’ in the British Hansard Corpus and a selection of Commons and Lords debates concerning British membership in international organisations as it relates to the League of Nations, United Nations, Council of Europe, EEC and Brexit. The collocates that were deemed to be politically significant are grouped in 13 loose semantic fields. This macro-level analysis of long-term trends of discourse is supplemented with an analysis of the said key debates in their historical contexts, including comparisons between the two Hou…

DECAY OF NONLOCALITY DUE TO ADIABATIC AND QUANTUM NOISE IN THE SOLID STATE

2010

We study the decay of quantum nonlocality, identified by the violation of the Clauser-Horne-Shimony-Holt (CHSH) Bell inequality, for two noninteracting Josephson qubits subject to independent baths with broadband spectra typical of solid state nanodevices. The bath noise can be separated in an adiabatic (low-frequency) and in a quantum (high-frequency) part. We point out the qualitative different effects on quantum nonlocal correlations induced by adiabatic and quantum noise. A quantitaive analysis is performed for typical noise figures in Josephson systems. Finally we compare, for this system, the dynamics of nonlocal correlations and of entanglement.

Independent Geometrical Control of Spin and Charge Resistances in Curved Spintronics

2019

Spintronic devices operating with pure spin currents represent a new paradigm in nanoelectronics, with higher energy efficiency and lower dissipation as compared to charge currents. This technology, however, will be viable only if the amount of spin current diffusing in a nanochannel can be tuned on demand while guaranteeing electrical compatibility with other device elements, to which it should be integrated in high-density three-dimensional architectures. Here, we address these two crucial milestones and demonstrate that pure spin currents can effectively propagate in metallic nanochannels with a three-dimensional curved geometry. Remarkably, the geometric design of the nanochannels can b…

An Interview with the Brother, Micheál Ó Nualláin

2015

This interview with Micheál Ó Nualláin, Brian O’Nolan’s brother and the only surviving member of his generation of the family, was conducted on 10 June 2014 in Monkstown, County Dublin. Its purpose was to obtain information about Brian O’Nolan’s private library at the John J. Burns Library, Boston College; the archive being the focal point of this issue of The Parish Review. It was Micheál who sold the last of his brother’s effects to Boston College in May 1997 and therefore he is in a position to answer questions about the purchase of the library, its contents and their provenance, and the reading practices of Brian and Evelyn O’Nolan.To read the article, click Download or View PDF.

Down and out in Italian towns: Measuring the impact of economic downturns on crime

2016

The paper investigates the effect of local economic conditions on crime. The study focuses on Italy’s local labor markets and analyzes the response of crime to the severe slump of 2007-2011. It shows that the downturn led to a significant increase in economic-related offenses that do not require particular criminal skills or tools (namely, thefts).

Neuroblastoma after Childhood: Prognostic Relevance of Segmental Chromosome Aberrations, ATRX Protein Status, and Immune Cell Infiltration

2014

AbstractNeuroblastoma (NB) is a common malignancy in children but rarely occurs during adolescence or adulthood. This subgroup is characterized by an indolent disease course, almost uniformly fatal, yet little is known about the biologic characteristics. The aim of this study was to identify differential features regarding DNA copy number alterations, α-thalassemia/mental retardation syndrome X-linked (ATRX) protein expression, and the presence of tumor-associated inflammatory cells. Thirty-one NB patients older than 10 years who were included in the Spanish NB Registry were considered for the current study; seven young and middle-aged adult patients (range 18-60 years) formed part of the c…

Ehlers-Danlos syndrome type VII: phenotype and genotype

1994

A patient suffering from a severe form of Ehlers-Danlos syndrome is presented (EDS type VII). The presence of bilateral congenital hip dislocation, generalized joint hypermobility and a soft hyperelastic skin with abnormal scarring suggested a specific collagen type I defect. SDS-PAGE analysis of collagens secreted into the medium of fibroblast cultures showed a retarded migration of more than half of the alpha 2(I) chains. CNBr peptide mapping of the HPLC-purified altered chain localized the mutant locus to the N-terminal region of the protein. cDNA analysis of the corresponding gene COL1A2 revealed, in addition to the expected collagen sequence, a transcript missing the entire exon 6. Thi…

Clinical effectiveness and safety of a distraction-rotation knee brace for medial knee osteoarthritis

2015

Abstract Objective Evaluation of the clinical effectiveness and safety of a new custom-made valgus knee brace (OdrA) in medial knee osteoarthritis (OA) in terms of pain and secondary symptoms. Methods Open-label prospective study of patients with symptomatic medial knee OA with clinical evaluation at 6 and 52 weeks (W6, W52). We systematically assessed pain on a visual analog scale (VAS), Knee injury and Osteoarthritis Outcome Score (KOOS), spatio-temporal gait variables, use of nonsteroidal anti-inflammatory drugs (NSAIDs) and analgesic-sparing effects of the brace and tolerance. Mean scores were compared at baseline, W6 and W52 and the effect size (ES) and 95% confidence intervals (95% CI…
