Vertical root fracture in endodontically treated teeth: A review of 25 cases
2001
Abstract Objective: We sought to examine the clinical conditions under which 25 endodontically treated teeth underwent vertical root fracture (VRF) and to relate this condition to the time elapsed from endodontic treatment to fracture. Study Design: This was a retrospective study in which we reviewed 25 case histories of patients with postendodontic VRF and studied the effect of various pretreatment and posttreatment factors as they related to VRF. Results And Conclusions: The mean time to VRF was 54 months; this was not significantly influenced by the presence or absence of prior restoration or by the presence or absence of a crown fitting. The use of a prefabricated, cylindrical, cemented…
Hsp60, a Novel Target for Antitumor Therapy: Structure-Function Features and Prospective Drugs Design
2013
Heat shock protein 60 kDa (Hsp60) is a chaperone classically believed to be involved in assisting the correct folding of other mitochondrial proteins. Hsp60 also plays a role in cytoprotection against cell stressors, displaying for example, antiapoptotic potential. Despite the plethora of studies devoted to the mechanism of Hsp60's function, especially in prokaryotes, fundamental issues still remain unexplored, including the definition of its role in cancer. Key questions still unanswered pertain to the differences in structure-function features that might exist between the well-studied prokaryotic GroEL and the largely unexplored eukaryotic Hsp60 proteins. In this article we discuss these …

Classification of Sound Scenes and Events in Real-World Scenarios with Deep Learning Techniques
2021
La clasificación de los eventos sonoros es un campo de la audición por computador que se está volviendo cada vez más interesante debido al gran número de aplicaciones que podrían beneficiarse de esta tecnología. A diferencia de otros campos de la audición por computador relacionados con la recuperación de información musical o el reconocimiento del habla, la clasificación de eventos sonoros tiene una serie de problemas intrínsecos. Estos problemas son la naturaleza polifónica de la mayoría de las grabaciones de sonido ambiental, la diferencia en la naturaleza de cada sonido, la falta de estructura temporal y la adición de ruido de fondo y reverberación en el proceso de grabación. Estos prob…
Fenomeni di polarizzazione in rivelatori Al/CdTe/Pt per spettroscopia X e gamma
2014
L’uso dei rivelatori a semiconduttore ha avuto, negli anni, un’importanza strategica nella spettroscopia X e gamma (1 keV – 2 MeV), con eccellenti risultati sia in applicazioni mediche che astrofisiche. L’imaging medicale (mammografia, tomografia computerizzata), il monitoraggio ambientale (radiazione di fondo), rivelatori da piano focale per telescopi X in astrofisica e sistemi di fluorescenza a raggi X nei Beni Culturali ne rappresentano alcune importanti applicazioni. I rivelatori a semiconduttore hanno trovato largo impiego grazie alle loro interessanti proprietà soprattutto se confrontate con i sistemi di rivelazione tradizionali (a gas e scintillatori); un migliore rapporto segnale-ru…
Związki duchowości z potraumatycznym rozwojem u kobiet po mastektomii – mediacyjna funkcja poczucia sensu życia
2020
Celem prezentowanych analiz było zbadanie relacji między wymiarami duchowości i poczucia sensu życia a potraumatycznym rozwojem u kobiet po mastektomii, a także określenie charakteru mediacyjnej funkcji poczucia sensu życia w relacjach duchowości i potraumatycznego rozwoju. Badaniami objęto 127 kobiet po operacyjnym leczeniu piersi z powodu nowotworu piersi, zrzeszonych w klubach „Amazonki” (M = 61,32 roku; SD = 10,28). W badaniach użyto następujących metod: Kwestionariusz Samoopisu, Inwentarz Potraumatycznego Rozwoju oraz Kwestionariusz Poczucia Sensu Życia. Analizy ujawniły dodatnie korelacje między duchowością, poczuciem sensu życia i potraumatycznym rozwojem oraz zróżnicowane związki mi…
Development of novel probes for enterovirus B group to study uncoating and infection
2016
Enterovirus B group (EV-B) viruses are important human pathogens which cause a variety of diseases from mild respiratory illnesses to more severe acute infections such as myocarditis and meningitis. EV-Bs have also been associated with chronic infections and autoimmune diseases such as type I diabetes. Because of their significance, better and more accurate methods are necessary to track and visualize viruses in vitro and in vivo. This thesis focus on the development of novel probes to label viruses site-specifically and track infection in vitro. First, we established a covalent conjugation between gold nanocluster markers and EV-B viruses. We were able to visualize through electron microsc…
Les dictionnaires de poche français-italien, italien-français (1710-2005)
2008
Les termes de poche ou de tascabile ont plusieurs synonymes, en français : portatif, abrégé, petit; en italien : portatile, compendiato, piccolo, compatto. L’utilisation de ces mots dépend de la date de publication des ouvrages. Les « portatifs » ou « poche » se définissent par rapport aux dictionnaires existants auxquels on les compare. Dans l’état actuel de nos recherches, on a pu dénombrer 283 dictionnaires de poche italien / français de 1710 à 2005. Les dictionnaires de spécialité existent aussi en poche, même si leur nombre est plutôt réduit (4% environ du total). Les périodes de plus grande publication correspondent, pendant le XIXe siècle, au premier Empire napoléonien, à la Monarchi…
Smoking a Dangerous Addiction: A Systematic Review on an Underrated Risk Factor for Oral Diseases
2021
Despite growing knowledge of the adverse effects of cigarette smoking on general health, smoking is one of the most widely prevalent addictions around the world. Globally, about 1.1 billion smokers and over 8 million people die each year because of cigarette smoking. Smoking acts as a source for a variety of oral and systemic diseases. Various periodontal issues such as increased pocket depth, loss of alveolar bone, tooth mobility, oral lesions, ulcerations, halitosis, and stained teeth are more common among smokers. This systematic review was conducted according to the guidelines from PRISMA, and research articles were retrieved from the Web database sources on 31 May 2021. The quality of …
Prior oral conditions in patients undergoing heart valve surgery
2017
Background Patients scheduled for heart valve surgery should be free of any oral infectious disorders that might pose a risk in the postoperative period. Few studies have been made on the dental conditions of such patients prior to surgery. The present study describes the most frequent prior oral diseases in this population group. Material and Methods A prospective, observational case-control study was designed involving 60 patients (30 with heart valve disease and 30 controls, with a mean age of 71 years in both groups). A dental exploration was carried out, with calculation of the DMFT (decayed, missing and filled teeth) index and recording of the periodontal parameters (plaque index, gin…
