Fundoplicatio sec. Nissen videolaparoscopica e metaplasia intestinale in esofago: osservazioni preliminari

2005

The aim of this preliminary study conducted in a few cases was the retrospective evaluation of the effects of laparoscopic Nissen fundoplication on oesophageal intestinal metaplasia. Seventy-seven patients with hiatal hernia underwent digital videofluorography, endoscopy with biopsies, motility studies and 24-h oesophageal pH-monitoring. On the basis of the results of the diagnostic procedures and considering the patients' ages and response to proton-pump inhibitor treatment, 8 patients underwent laparoscopic Nissen fundoplication; in 5 cases intestinal metaplasia was present at histopathological examination. Two of these had Barrett's oesophagus at endoscopy and intestinal metaplasia was a…

Coherent neutrino scattering

2009

We present a microscopic model for coherent pion production off nuclei induced by neutrinos. This model is built upon a model for single nucleon processes that goes beyond the usual Delta dominance by including non resonant background contributions. We include nuclear medium effects: medium corrections to Delta$ properties and outgoing pion absortion via an optical potential. This results in major modifications to cross sections for low energy experiments when compared with phenomenological models like Rein-Sehgal's.

Frequency-specific network activity predicts bradykinesia severity in Parkinson’s disease

2021

Highlights • Parallel subnetworks are affected in bradykinesia. • The primary motor and the premotor cortex are common nodes with task-specificity. • Beta activity decreases, gamma activity increases with improvement of bradykinesia. • Subthalamic stimulation reduces beta, increases gamma power in ipsilateral cortex. • Subnetworks act with frequency-specific oscillations.

Advanced microscopy analysis of the micro-nanoscale architecture of human menisci

2019

AbstractThe complex inhomogeneous architecture of the human meniscal tissue at the micro and nano scale in the absence of artefacts introduced by sample treatments has not yet been fully revealed. The knowledge of the internal structure organization is essential to understand the mechanical functionality of the meniscus and its relationship with the tissue’s complex structure. In this work, we investigated human meniscal tissue structure using up-to-date non-invasive imaging techniques, based on multiphoton fluorescence and quantitative second harmonic generation microscopy complemented with Environmental Scanning Electron Microscopy measurements. Observations on 50 meniscal samples extract…

Interlinkages between operational conditions and direct and indirect greenhouse gas emissions in a moving bed membrane biofilm reactor

2016

Nitrous oxide (N2O) can be emitted during wastewater treatment contributing to the global warming due to its high global warming potential,. During the last ten years, several efforts have been provided to improve knowledge on: key mechanisms, operating factors and influent features affecting the N2O production/emission. However, the knowledge on the investigated issues is not completely mature. Indeed, in terms of mathematical modelling, literature shows that a reliable model has not yet been established due to the huge data set required and the complexity of the mechanistic models indicated as the most accurate. In this work, the first attempt to perform a multiregression analysis is pres…

THE ROLE OF ACCOUNTABILITY WITHIN A ZERO WASTE STRATEGY: EVIDENCES FROM A SICILIAN SMALL MUNICIPALITY

2017

Building a sustainable city model comprising an integrated waste management system has become an indispensable choice, also in the light of increasingly stringent regulatory constraints. The core point of the paper is the implementation of a zero waste strategy in a small municipality in Sicily. Given that only the unceasing participation of citizens may ensure the persistence over time of such a policy, accountability process works letting citizens approach directly the end-results of their ongoing good practices. By building up a SD model framed by a DPM chart, it is possible to figure out how disclosure of public saving resulting from the decreasing amount of waste piled up in the landfi…

THE IMPACT OF TAX COMPETITION AND HARMONISATION IN THE EU IN RELATION TO FISCAL OPTIMISATION

2018

Fiscal competition and harmonisation are topical issues and the controversy generated by preferences for one or the other is due to the effects they generate in the economies of the EU member states. The practice of tax competition to a smaller or larger extent by some of the Member States is often identified with tax optimisation practices. Thus, in the economies of developed or emerging countries, the effects are both on the labour market, in the collection of indirect taxes (VAT or excise duties), but also in the transfer of profits versus transfer prices. The European fora are working hard for the uniformity of European legislation, but also to determine the governments of the Member St…

Corporate social irresponsibility: review and conceptual boundaries

2017

PurposeThe purpose of this paper is to carry out a review of the academic literature about corporate social irresponsibility (CSIR) highlighting aspects that help us to define socially irresponsible behaviour and its relationship with socially responsible behaviour.Design/methodology/approachThrough a Boolean search of studies related to terms of irresponsibility undertaken from 1956 to October 2016, the authors develop a review of the literature focussing on the main perspectives used for defining the term of CSIR.FindingsThe paper provides a framework of three main dimensions for understanding the differences in the literature that defines CSIR: who defines irresponsible behaviour, an imp…
