The potential therapeutic effect of quinic acid evaluated by global gene expression of Streptococcus mutans, the etiological agent of dental caries
No full textLa carie dentale è una malattia ampiamente diffusa che porta a danni a carico dei denti e, se non adeguatamente trattata, alla perdita degli stessi. Una corretta igiene orale e la somministrazione di sostanze in grado di fortificare lo smalto dentale rappresentano delle pratiche comuni nella prevenzione delle lesioni cariose; tuttavia, diverse linee di ricerca su metodi o sostanze in grado di inibire lo sviluppo della carie sono ancora in corso. In particolare, essendo negli ultimi anni aumentata l’attenzione verso i composti naturali, diversi studi sono stati condotti al fine di confermare i benefici effetti che i componenti di alimenti e bevande, in particolare polifenoli, esercitano sulla salute orale.
Lo scopo di questa tesi di dottorato è stato quello di studiare gli effetti dell’ acido chinico (QA) (un composto appartenente alla famiglia dei polifenoloi) sulla espressione genica globale di S. mutans, l'agente eziologico della carie dentale.Dental caries is a costly and widespread disease that leads to dental damage and, finally, to tooth loss. Oral hygiene and fluoride administration are commonly applied to prevent caries lesion formation, however, several research lines on methods or substances inhibiting caries development are still in progress. In recent years, as the attention towards natural compounds is increased in the consumers, several studies have been conducted in order to confirm the beneficial effects that food/beverage components, especially polyphenols, exert on the oral health.
The aim of this doctoral thesis was to study the effects of quinic acid (QA) (a polyphenol compound) on global gene expression of S. mutans, the etiological agent of human dental caries

Journal of Corpora & Discourse Studies
No full textThe Journal of Corpora and Discourse Studies showcases research into language as a vehicle of communication which incorporates the use of corpus techniques. The Journal is highly interdisciplinary in nature, first, in combining discourse analysis with corpus linguistics and, second, in accommodating an ever-increasing number of other disciplines which employ the analysis of spoken or written texts beyond linguistics proper which use corpus techniques to help analyse the texts they employ, including political science, sociology, history, literary criticism, business studies, healthcare, and many more. We particularly welcome papers which address methodological issues concerning the use of corpora in these and other fields. The journal is on-line open-access with the opportunity to store research data on the publisher’s server. The language of publication is English, but we welcome submissions on all other languages. Published by Cardiff University Press. Editor in chief, Alan Partington. Editors, Costas Gabrielatos and Amanda Potts. Reviews editor, Sylivia Jaworska. Technical editor, Jane Johnson. The first issue is planned for July 2018
Get back! Methods for Exploring Discourses of Nostalgia and Nostalgic Discourses Using Corpora
Full text linkNostalgia for something lost (factual or imagined) has shaped nations and continues to shape national self-image and policies. The rhetorical appeal to nostalgia has been blamed for a range of phenomena, from populism to reactionary politics at large, and yet research in psychology has suggested that nostalgising has a beneficial cognitive function. The dissonance between the negative reputation of nostalgia and the science of how it works for us, as a positive and useful emotion, is related to the fact that nostalgia is not a given content, but a situated cultural practice. I here use corpus linguistics methods to pursue the mismatch between the “discourse of nostalgia” and “nostalgic discourses” and to move from expressions that denote nostalgia, to expressions that signal it. This paper reports on the methodological explorations analysing large newspaper corpora and working on the overlaps between the collocational profile of nostalgia and the markers of nostalgic discourse. The aim is to exploit corpus studies’ ability to systematically analyse patterns as a gateway to access nostalgic narratives. Nostalgia is, in fact, intrinsically discursive: it is a story of transformation and it is the story of felt absences in the present compared to an ‘elsewhen’. Understanding the narratives of nostalgia and identifying a typology of nostalgic discursive triggers may offer insights into how this pervasive, powerful and often profitable emotion gains purchase in public discourse
Self-reflexive Journalism. A corpus study of journalistic culture and community in the Guardian.
No full textThis book develops a corpus-assisted approach to the study of self-reflexivity in journalism and examines the ways in which news workers and subsequently, news organizations, choose to promote an identity for themselves and the ideologies that accompany them. Using The Guardian as a case study, the volume draws on its Corpus Assisted Discourse Studies (CADS) to explore ways in which a newspaper can reflect upon itself, including how newspapers conceptualize the role of the media, how they define good vs. bad journalism, what they see as professional values, how they attempt to cement community membership amongst their readers, how they construct and project their overall identity and role as newspapers and also how they see their position within the larger community. A chapter on the book’s methodological framework reflects on critical aspects of CADS, including triangulation, objectivity and subjectivity, total accountability, and replicability. CADS methods are applied in the analysis chapters, with accompanying reflections on what we learn about the strengths and also maybe about some of the limitations of corpus methodology. A summarizing chapter ties these strands together to make the case for a CADS approach to journalism and media studies and look to the future at how the digital age has shaped the journalism landscape. With its focus in extending a CADS approach to other aspects of journalism scholarship, this volume is key reading for graduate students and researchers in corpus linguistics, discourse analysis, media studies, and journalism studies
