Calcium sulfate and PTFE nonporous barrier for regeneration of experimental bone defects
2008
Made available in DSpace on 2022-04-28T18:55:46Z (GMT). No. of bitstreams: 0 Previous issue date: 2008-06-01 The aim of the study was to evaluate the possibility to obtain guided bone regeneration with two types of physical barriers (calcium sulfate and PTFE nonporous barrier) in surgical defects created in rat parietal bones. In the right parietal bone the calcium sulfate barrier filled out the whole defect and in the left parietal bone the barrier of PTFE was positioned in the floor and externally to the surgical defect. After 7, 14, 30 and 45 days four animals were sacrificed in each period and the bone containing the defects were submitted to the microscopic analysis. The results of the…
In situ observation of new particle formation (NPF) in the tropical tropopause layer of the 2017 Asian monsoon anticyclone - Part 2: NPF inside ice c…
2021
From 27 July to 10 August 2017, the airborne StratoClim mission took place in Kathmandu, Nepal, where eight mission flights were conducted with the M-55 Geophysica up to altitudes of 20 km. New particle formation (NPF) was identified by the abundant presence of nucleation-mode aerosols, with particle diameters dp smaller than 15 nm, which were in-situ-detected by means of condensation nuclei (CN) counter techniques. NPF fields in clear skies as well as in the presence of cloud ice particles (dp > 3 µm) were encountered at upper troposphere–lowermost stratosphere (UTLS) levels and within the Asian monsoon anticyclone (AMA). NPF-generated nucleation-mode particles in elevated concentration…
Dressed emitters as impurities
2021
Dressed states forming when quantum emitters or atoms couple to a photonic bath underpin a number of phenomena and applications, in particular dispersive effective interactions occurring within photonic bandgaps. Here, we present a compact formulation of the resolvent-based theory for calculating atom-photon dressed states built on the idea that the atom behaves as an effective impurity. This establishes an explicit connection with the standard impurity problem in condensed matter. Moreover, it allows us to formulate and settle in a model-independent context a number of properties previously known only for specific models or not entirely formalized. The framework is next extended to the cas…
Multi-sensory approaches to (audio) describing the visual arts
2012
Making art accessible to blind patrons requires the ability to convey explicit and implicit visual messages through non-visual forms. Audio description is often seen as the best way to offer visual texts to blind people; however, one may query whether words alone are sufficient to convey the subtleties of art and to transport the emotional charge such works offer. It is a fact that the dialogue between words and touch may allow these particular “readers” to “see” art in its tangible forms, but perhaps more is needed if one is to give them the opportunity to live the art experience to the full. This article discusses different multi-sensory approaches to making art available to visually impa…
Architectures for autism
2015
Le ricerche condotte sulle malattie degenerative della "terza età", hanno visto negli ultimi anni il gruppo di studio palermitano indagare e proporre soluzioni che vanno dalla stesura di linee guida per la progettazione di Residenze Sanitarie Assistenziali (RSA), alla progettazione esecutiva di architetture residenziali, al recupero e riuso di edilizia già esistente fino alla progettazione dello spazio domestico dedicato e protetto, che oltre a fornire risposte funzionali ne ha anche esaltato il design degli elementi di arredo. A questo ambito di ricerca da circa due anni si è affiancato un nuovo settore di indagine indirizzato sempre alle "minoranze sociali". Research conducted on degenera…
Choosing the Right Antifungal Agent in ICU Patients
2019
Fungi are responsible for around 20% of microbiologically documented infections in intensive care units (ICU). In the last decade, the incidence of invasive fungal infections (IFI), including candidemia, has increased steadily because of increased numbers of both immunocompromised and ICU patients. To improve the outcomes of patients with IFI, intensivists need to be aware of the inherent challenges. This narrative review summarizes the features of routinely used treatments directed against IFI in non-neutropenic ICU patients, which include three classes of antifungals: polyenes, azoles, and echinocandins. ICU patients' pathophysiological changes are responsible for deep changes in the phar…
Adherence to international guidelines for the management of Helicobacter pylori infection among gastroenterologists and gastroenterology fellows in I…
2021
Background: Information on the management of Helicobacter (H.) pylori infection by gastroenterologists and gastroenterology fellows are scarce. We aimed to assess practice of gastroenterologists and gastroenterology fellows and their adherence to guidelines for diagnosis and treatment of H. pylori infection in Italy. Materials and Methods: All gastroenterologists and gastroenterology fellows attending the National Congress of Digestive Diseases - FISMAD were invited to fill-in an on-line questionnaire. The questionnaire included questions on the diagnosis and treatment of H. pylori infection. Results: A total of 279 gastroenterologists and 61 gastroenterology fellows participated to the stu…
Gene therapy with growth factors for periodontal tissue engineering : a review
2011
The treatment of oral and periodontal diseases and associated anomalies accounts for a significant proportion of the healthcare burden, with the manifestations of these conditions being functionally and psychologically debilitating. A challenge faced by periodontal therapy is the predictable regeneration of periodontal tissues lost as a consequence of disease. Growth factors are critical to the development, maturation, maintenance and repair of oral tissues as they establish an extra-cellular environment that is conducive to cell and tissue growth. Tissue engineering principles aim to exploit these properties in the development of biomimetic materials that can provide an appropriate microen…
Effectiveness of training in guideline-oriented biopsychosocial management of low-back pain in occupational health services – a cluster randomized co…
2021
Objective This study aimed to investigate the effectiveness of brief training in the guideline-oriented biopsychosocial management of low-back pain (LBP) in occupational health services using a cluster-randomized design. A small sample of physiotherapists and physicians from the intervention units (N=12) were given three- to seven-day training focusing on the biopsychosocial management of LBP, while professionals in the control units (N=15) received no such training. Methods Eligible patients with LBP, with or without radicular pain, aged 18-65, were invited to participate. A web-based questionnaire was sent to all recruited patients at baseline, three months and one year. The primary outco…
Guided Optical Waves in a Ferroelectric Liquid Crystal Layer: A Birefringence Analysis of Molecular Orientation on the Switching Process
1995
Abstract Guided optical waves are very sensitive to the alteration of optical properties of dielectric media. In this report, we demonstrate the use of guided waves for studying dynamic behavior of ferroelectric liquid crystals. Propagating light in the anisotropic medium suffers a birefringent effect, which causes coupling of p- and s-polarized light. Theoretical calculations, based on the Maxwell equations, successfully describe this phenomena, using a dielectric tensor diagonal in molecular coordinates, which is transformed to the laboratory coordinate system by three Euler angles. The waveguide measurements are able to probe the molecular orientation and movement of the liquid crystal m…
