A Teledentistry system for the second opinion

2014

In this paper we present a Teledentistry system aimed to the Second Opinion task. It make use of a particular camera called intra-oral camera, also called dental camera, in order to perform the photo shooting and real-time video of the inner part of the mouth. The pictures acquired by the Operator with such a device are sent to the Oral Medicine Expert (OME) by means of a current File Transfer Protocol (FTP) service and the real-time video is channeled into a video streaming thanks to the VideoLan client/server (VLC) application. It is composed by a HTML5 web-pages generated by PHP and allows to perform the Second Opinion both when Operator and OME are logged and when one of them is offline.

HCI for biomedical decision-making: From diagnosis to therapy.

2020

Abstract Human-Computer Interaction (HCI) plays a fundamental role in the design of software oriented towards clinical decision-making tasks. Currently, physicians have to deal with an ensemble of systems and software tools in the clinical environment, such as clinical Decision Support Systems (CDSSs), Electronic Health Records (EHRs), Picture Archiving and Communication Systems (PACSs). Moreover, additional platforms aim at collaborative work particularly in telemedicine, where rehabilitation technologies and conversational agents can support the healthcare professionals.

Imaging synaptic zinc release in living nervous tissue

2001

Zinc enriched neurons have a pool of synaptic vesicles which contain free or loosely-bound zinc ions. The movement of the vesicular zinc ions into the synaptic clefts has been previously studied by microdialysis, fluorescence postmortem staining for zinc and radioactive zinc isotope. In this study the zinc fluorescence probe N-6-metoxy-p-toluensulfonamide quinoline (TSQ) has been applied as a tracer of synaptic release of zinc ions. This fluorochrome permeates cell membranes and when exposed to living brain slices gives rise to a staining pattern similar to that seen with autometallography. In the living brain slices, fluorescence emission persists after exposure to calcium saturated ethyle…

The Public-Key-Infrastructure of the Radiological Society of Germany.

2005

Pretty Good Privacy (PGP) encoding is based on the Public-Key-Procedure and permits the safe transmission of medical data. Furthermore it allows the use of an electronic signature provided that keys used belong to the key owner and that the key owner's identity is guaranteed by a trusted third party. Under the auspices of the Radiological Society of Germany (Deutsche Rontgengesellschaft, DRG) its IT-Working Group (Arbeitsgemeinschaft fur Informationstechnik, @GIT) built up an appropriate Certification Authority including the required Public-Key-Infrastructure. These @GIT certified PGP keys allow the legal use of telemedicine in Germany. Digital signatures based to those certified keys corre…

Abstract Ultrasound enhances the rate of reductive cleavage of the C6–oxygen bond of sesquiterpene enonelactones. trans-Eudesmanolides 1c–1g, cis-eudesmanolides 2a–2c, and trans-guaianolides 4a–4d react with Zn in acetic acid–H2O under sonochemical conditions to afford the corresponding sesquiterpene acids 3a–3g and 5a–5d, respectively in good yields. Starting from 5d two natural guaianes 1α,7α,10αH-guaian-4,11-dien-3-one (6) and hydrocolorenone (7) have been prepared in good yields through a straightforward sequence.

ChemInform Abstract: Ultrasound-Assisted Reductive Cleavage of Sesquiterpene γ- Enonelactones.

2010

Abstract Ultrasound enhances the rate of reductive cleavage of the C 6 -oxygen bond of several cis - and trans - sesquiterpene γ-enonelactones. Interestingly ultrasound overrides the stereoelectronic requirements for the reductive cleavage of the most usually occurring sesquiterpene trans -lactones.

La enseñanza monumentalista y utilitarista de las causas de la biodiversidad y de las estrategias para su conservación: un estudio sobre la transposi…

2015

Este trabajo estudia la presencia y complejidad en el tratamiento de las causas de la biodiversidad y de las razones para su conservación que realizan manuales escolares de la Educación Secundaria de España. Para ello, se determinó el ámbito conceptual y axiológico que define la comunidad de expertos, se examinó el tratamiento propuesto en el currículo español y se analizaron 50 manuales escolares (27 de la Educación Secundaria Obligatoria –ESO – y 30 del Bachillerato). Los resultados mostraron que el proceso de transposición didáctica vuelve monumentalista la enseñanza de la biodiversidad, ya que olvida las razones de su existencia, y se enriquece de connotaciones biologicistas y utilitari…

La stereotomia nella cattedra di Architettura statica di Carlo Giachery

2014

La scuola di architettura di Palermo, sin dalla sua fondazione nel 1779, con la creazione della cattedra di Architettura civile affidata a Giuseppe Venanzio Marvuglia, era divenuta inevitabilmente il luogo di verifica e talvolta di esplorazione dei temi legati alla pratica professionale e, quindi, all’arte del costruire. Giachery, Professore di Architettura statica e civile dal 1837 al 1865, è il primo ad avvertire, da docente, la crisi profonda del sistema didattico della scuola di architettura di Palermo isterilita dalla ricerca di astratte idealità neoclassiche e straniatasi dal processo evolutivo della cultura architettonica europea dopo la morte dei “maestri” Marviglia e Gentile. Secon…
