    The frequency of renal vascular lesions (RVL) and their relevance in the progression of renal damage were evaluated by the Pathology Group of the "Gruppo Italiano per lo Studio della Nefrite Lupica" (GISNEL). Of 285 patients with lupus nephritis collected from 20 nephrology centers in Italy and classified according to World Health Organization (WHO) criteria, 79 cases (27.7%) with RVL were identified and classified as follows: (1) lupus vasculopathy (n = 27); (2) hemolytic-uremic syndrome/thrombotic thrombocytopenic purpura (HUS/TTP) malignant hypertension-like lesions (n = 24); (3) vasculitis (n = 8); (4) arterio-arteriosclerosis (n = 20). At the time of renal biopsy, patients with RVL had mean serum creatinine levels significantly higher than patients without RVL (201.8 +/- 195.9 mumol/L [2.2 +/- 2.2 mg/dL] v 108.1 +/- 108.0 mumol/L [1.2 +/- 1.2 mg/dL]; P less than 0.01). Hypertension was more frequent in patients with RVL than in those without (68.4% v 30.5%; P less than 0.01). The probability of kidney survival assessed according to the Kaplan-Meier method at 5 and 10 years was, respectively, 74.3% +/- 5.9% and 58.0% +/- 8.9% in patients with RVL, compared with 89.6% +/- 2.7% and 85.9% +/- 3.7% in patients without RVL. However, the two groups did not differ significantly as regards overall survival, the probability of survival at 5 and 10 years being 86.5% +/- 4.5% and 78.8% +/- 6.6% in patients with RVL and 92.2% +/- 2.2% and 83.3% +/- 4.4% in patients without RVL.(ABSTRACT TRUNCATED AT 250 WORDS)

    The Gruppo Italiano per lo Studio della Sopravvivenza nell'Infarto Miocardico-Heart Failure (GISSI-HF) study reported benefits of n-3 fatty acid (FA) treatment on cardiovascular (CV) events, but the effects of treatment on a putative CV disease risk factor, the red blood cell (RBC) n-3 FA level (the omega-3 index), have not been examined in this context. We hypothesized that treatment with prescription omega-3 acid ethyl esters (O3AEE) would increase the omega-3 index to the proposed cardioprotective value of 8%. RBCs were collected from a subset of patients participating in the GISSI-HF study (n=461 out of 6975 randomized), at baseline and after 3 months of treatment with either an olive oil placebo or O3AEE (1 g/d). RBC FA levels were expressed as a percentage of total FA. Patients also reported their typical olive oil and fish intakes. RBC oleic acid levels were directly correlated with reported frequency of olive oil consumption, and the omega-3 index was correlated with reported fish intake (P for trends <0.001 for both). After treatment, the omega-3 index increased from 4.8±1.7% to 6.7±1.9% but was unchanged in the placebo group (4.7±1.7 to 4.8±1.5%) (P<.0001 for changes between groups). At 3 months, more patients reached the proposed target omega-3 index level of 8%-12% in the treated vs placebo group (22.6% vs. 1.3%, P<.0001), however, what omega-3 index levels were ultimately achieved after four years in this trial are unknown.

    2006-12-01

    In the Fall of 2005 we began offering a calculus-based first-year, two-course introductory physics sequence using the studio format, based on Workshop Physics[1] by P. Laws etal. We will recount our experiences in introducing a workshop-based physics course at a large Canadian university from the initial push to the final implementation. In particular, we will discuss the details of our curriculum and what modifications were made to align our Studio Physics I&II courses with the currently existing lecture courses. This involved, among other things, adapting some of our first-year physics laboratory experiments in optics and electricity and magnetism to the workshop format. We will also discuss the myriad of obstacles that were encountered along the way. The results of before-and-after FCI testing for the first two offerings of Studio Physics I will also be presented along with student feedback from course evaluations. And finally, we will elaborate on our plans for the future.

    RIASSUNTO. Scopo. Descrivere il management di un paziente con malattia di Marchiafava-Bignami (MBD) associata a lesioni frontali corticali, senza sintomi specifici al primo accesso in Pronto Soccorso, e insorgenza tardiva di sintomi psichiatrici atipici. Metodi. Descriviamo il caso di un paziente di 44 anni con storia di abuso cronico di alcol, a cui è stata diagnosticata la MBD. Risultati. La risonanza magnetica ha evidenziato lesioni nello splenio e corpo del corpo calloso e lesioni bilaterali della corteccia frontale. Il paziente ha sviluppato sintomi psichiatrici atipici a insorgenza tardiva, che sono risultati essere resistenti alle terapie farmacologiche impostate. Discussione. Il caso che descriviamo sembra supportare le attuali, ma ancora scarse evidenze che descrivono il coinvolgimento corticale nella MBD, suggerendone l'associazione con una prognosi peggiore. I sintomi psichiatrici possono risultare difficili da trattare a causa della resistenza alle terapie. Conclusione. Il coinvolgimento di psichiatri, radiologi e neurologi secondo un approccio di consultazione-liaison si è dimostrato di fondamentale importanza per la diagnosi e l'impostazione della terapia adeguata al paziente.

  11. Mission interactive scenarion studio for autonomous spacecraft

    NASA Technical Reports Server (NTRS)

    Starbird, T. W.; Lin, I.; Ko, A.

    2003-01-01

    We propose building a Studio enabling the use of diverse existing mission activity and scenario patterns, the creation of new ones, and the modeling of their effects using existing modeling tools. The core of the Studio is a component-based Type Library, which captures years of mission adaptation patterns in various forms. The Studio works as a content server to capture the developed adaptation knowledge for reuse and provides bridging into different mission uplink implementations, including the Mission Data System [l] (MDS) state/goal machinery. Various activities can be coordinated, controlled, and reused through the Studio's component interface to establish and model a mission scenario. A special component Factory mechanism will be in place to facilitate the adaptation of projects into the Studio. The architecture of the Studio reflects and enforces a division of knowledge and actions into three parts: Model, Controller, Viewer. The Model contains information about (a proposed version of) the spacecraft and mission. The Controller contains logic for constructing scenarios of mission activities. The information in the Model and Controller is principally in the form of reusable patterns. A Viewer can be a simple or complex software system. For example, Apgen [2,3] is one possible viewer, MDS is another. A 3-tiered infrastructure is used for the Studio, reflecting the Model, Controller, Viewer architecture [4,5]. The Studio is useful in pre-phase A of a project by enabling spacecraft design options to be played against desired mission scenarios. In later design phases of a project, the construction and modeling of more detailed scenarios is supported by the Studio.

    2013-01-01

    Physics Studio teaching was recently introduced at an international and multicultural academic program of a U.S. university in Panama. The results of introducing and implementing studio-style teaching on the conceptual understanding of calculus-based introductory physics have been measured by comparing before and during studio implementation. The research was carried on over the last five years in different semesters. The measurement tool was the Force Concept Inventory. The initial learning stage of the incoming diverse students has been found to be at a significantly lower level than generally reported in the U.S. The normalized gain in conceptual understanding was significantly larger than in the former traditional system, and has become consistent in the last semesters. Multicultural aspects that may affect the entry level and performance enhancement are discussed.

  7. CS-Studio Scan System Parallelization

    SciTech Connect

    Kasemir, Kay; Pearson, Matthew R

    2015-01-01

    For several years, the Control System Studio (CS-Studio) Scan System has successfully automated the operation of beam lines at the Oak Ridge National Laboratory (ORNL) High Flux Isotope Reactor (HFIR) and Spallation Neutron Source (SNS). As it is applied to additional beam lines, we need to support simultaneous adjustments of temperatures or motor positions. While this can be implemented via virtual motors or similar logic inside the Experimental Physics and Industrial Control System (EPICS) Input/Output Controllers (IOCs), doing so requires a priori knowledge of experimenters requirements. By adding support for the parallel control of multiple process variables (PVs) to the Scan System, we can better support ad hoc automation of experiments that benefit from such simultaneous PV adjustments.

  8. Fruit growth in Arabidopsis occurs via DELLA-dependent and DELLA-independent gibberellin responses.

    PubMed

    Fuentes, Sara; Ljung, Karin; Sorefan, Karim; Alvey, Elizabeth; Harberd, Nicholas P; Østergaard, Lars

    2012-10-01

    Fruit growth and development depend on highly coordinated hormonal activities. The phytohormone gibberellin (GA) promotes growth by inducing degradation of the growth-repressing DELLA proteins; however, the extent to which DELLA proteins contribute to GA-mediated gynoecium and fruit development remains to be clarified. Here, we provide an in-depth characterization of the role of DELLA proteins in Arabidopsis thaliana fruit growth. We show that DELLA proteins are key regulators of reproductive organ size and important for ensuring optimal fertilization. We demonstrate that the seedless fruit growth (parthenocarpy) observed in della mutants can be directly attributed to the constitutive activation of GA signaling. It has been known for >75 years that another hormone, auxin, can induce formation of seedless fruits. Using mutants with complete lack of DELLA activity, we show here that auxin-induced parthenocarpy occurs entirely through GA signaling in Arabidopsis. Finally, we uncover the existence of a DELLA-independent GA response that promotes fruit growth. This response requires GIBBERELLIN-INSENSITIVE DWARF1-mediated GA perception and a functional 26S proteasome and involves the basic helix-loop-helix protein SPATULA as a key component. Taken together, our results describe additional complexities in GA signaling during fruit development, which may be particularly important to optimize the conditions for successful reproduction.

  19. City Scale Modeling with OpenStudio

    SciTech Connect

    2016-08-12

    Assessing the impact of energy efficiency technologies at a district or city scale is of great interest to local governments, real estate developers, utility companies, and policymakers. This paper describes a flexible framework that can be used to create and run district and city scale building energy simulations. The framework is built around the new OpenStudio City Database (CityDB). Building footprints, building height, building type, and other data can be imported from public records or other sources. Missing data can be inferred or assigned from a statistical sampling of other datasets. Once all required data is available, OpenStudio Measures are used to create starting point energy models and to model energy efficiency measures for each building. Together this framework allows a user to pose several scenarios such as 'what if 30% of the commercial retail buildings added rooftop solar' or 'what if all elementary schools converted to ground source heat pumps' and then visualize the impacts at a district or city scale. This paper focuses on modeling existing building stock using public records. However, the framework is capable of supporting the evaluation of new construction, district systems, and the use of proprietary data sources.

    Walker, La Tonya Nicole; Malczynski, Leonard A.

    2014-02-01

    DYNAMO is a computer program for building and running 'continuous' simulation models. It was developed by the Industrial Dynamics Group at the Massachusetts Institute of Technology for simulating dynamic feedback models of business, economic, and social systems. The history of the system dynamics method since 1957 includes many classic models built in DYANMO. It was not until the late 1980s that software was built to take advantage of the rise of personal computers and graphical user interfaces that DYNAMO was supplanted. There is much learning and insight to be gained from examining the DYANMO models and their accompanying research papers. We believe that it is a worthwhile exercise to convert DYNAMO models to more recent software packages. We have made an attempt to make it easier to turn these models into a more current system dynamics software language, Powersim © Studio produced by Powersim AS2 of Bergen, Norway. This guide shows how to convert DYNAMO syntax into Studio syntax.

  2. Color studio in crisis: embracing change

    NASA Astrophysics Data System (ADS)

    Smith, Dianne

    2002-06-01

    Teaching color to students of architecture and design within the higher education sector is becoming more of a luxury than of core business. With increasing financial demands, reduced resources, and increasing student numbers, educators are required to think laterally to cater for change without sacrificing learning objectives. This paper raises some of the issues involved in the educative climate within one Australian university setting. Using a reflective narrative, educational objectives are defined, the implementation of new modes of 'teaching' as a means of coping with higher student numbers and reduced staffing and technical resources are described, and the outcomes in terms of student learning over an eight year period are critiqued. Institutional management policy is forcing the educator to re-evaluate the value of the traditional studio, and the intensive 'hands- on' interactive approach that traditionally is integral to such an approach. As curriculum development involves not only theory and project work, the classroom culture, the physical environment and the University and School context need to be addressed. Generic skills, in association with professional knowledge and skills, should be addressed, and therefore, opportunities for teaching a traditionally studio-based subject on-line as a computer based unit would appear to be limited. This discussion aims to pose questions, as well as reflecting upon successes and failures in this area of education within the University context. There is a need to embrace the contextual demands while ensuring that the student knowledge of color , and the joy of discovering its characteristics in practice, are not sacrificed but enhanced.

  10. DELLA proteins regulate arbuscule formation in arbuscular mycorrhizal symbiosis.

    Floss, Daniela S; Levy, Julien G; Lévesque-Tremblay, Véronique; Pumplin, Nathan; Harrison, Maria J

    2013-12-17

    Most flowering plants are able to form endosymbioses with arbuscular mycorrhizal fungi. In this mutualistic association, the fungus colonizes the root cortex and establishes elaborately branched hyphae, called arbuscules, within the cortical cells. Arbuscule development requires the cellular reorganization of both symbionts, and the resulting symbiotic interface functions in nutrient exchange. A plant symbiosis signaling pathway controls the development of the symbiosis. Several components of the pathway have been identified, but transcriptional regulators that control downstream pathways for arbuscule formation are still unknown. Here we show that DELLA proteins, which are repressors of gibberellic acid (GA) signaling and function at the nexus of several signaling pathways, are required for arbuscule formation. Arbuscule formation is severely impaired in a Medicago truncatula Mtdella1/Mtdella2 double mutant; GA treatment of wild-type roots phenocopies the della double mutant, and a dominant DELLA protein (della1-Δ18) enables arbuscule formation in the presence of GA. Ectopic expression of della1-Δ18 suggests that DELLA activity in the vascular tissue and endodermis is sufficient to enable arbuscule formation in the inner cortical cells. In addition, expression of della1-Δ18 restores arbuscule formation in the symbiosis signaling pathway mutant cyclops/ipd3, indicating an intersection between DELLA and symbiosis signaling for arbuscule formation. GA signaling also influences arbuscule formation in monocots, and a Green Revolution wheat variety carrying dominant DELLA alleles shows enhanced colonization but a limited growth response to arbuscular mycorrhizal symbiosis.

    2012-09-01

    The Colorado School of Mines (CSM) has taught its first-semester calculus-based introductory physics course (Physics I) using a hybrid lecture/Studio Physics format since the spring of 1997. Starting in the fall of 2007, we have been converting the second semester of our calculus-based introductory physics course (Physics II) to a hybrid lecture/Studio Physics format, beginning from a traditional lecture/lab/recitation course. In this paper, we document the stages of this transformation, highlighting what has worked and what has not, and the challenges and benefits associated with the switch to Studio Physics. A major goal in this study is to develop a method for secondary implementations of Studio physics that keeps the time and resource investments manageable. We describe the history of Studio at CSM and characterize our progress via several metrics, including pre/post Conceptual Survey of Electricity and Magnetism (CSEM) scores, Colorado Learning About Science Survey scores (CLASS), exam scores, failure rates, and a variety of qualitative observations. Results suggest that Studio has increased student performance and satisfaction despite an aggressive expansion of class sizes in the past few years. Gains have been concentrated mostly in problem-solving skills and exam performance (as opposed to conceptual survey gains), in contrast to what has sometimes been seen in other studies.

  13. Modeling lift operations with SASmacr Simulation Studio

    NASA Astrophysics Data System (ADS)

    Kar, Leow Soo

    2016-10-01

    Lifts or elevators are an essential part of multistorey buildings which provide vertical transportation for its occupants. In large and high-rise apartment buildings, its occupants are permanent, while in buildings, like hospitals or office blocks, the occupants are temporary or users of the buildings. They come in to work or to visit, and thus, the population of such buildings are much higher than those in residential apartments. It is common these days that large office blocks or hospitals have at least 8 to 10 lifts serving its population. In order to optimize the level of service performance, different transportation schemes are devised to control the lift operations. For example, one lift may be assigned to solely service the even floors and another solely for the odd floors, etc. In this paper, a basic lift system is modelled using SAS Simulation Studio to study the effect of factors such as the number of floors, capacity of the lift car, arrival rate and exit rate of passengers at each floor, peak and off peak periods on the system performance. The simulation is applied to a real lift operation in Sunway College's North Building to validate the model.

  14. Xerox Color Systems Studio: developing customer-research relationships

    NASA Astrophysics Data System (ADS)

    Buckley, Robert R.; Adams, Ann D.

    1993-08-01

    Researching color documents and the systems that produce them requires a new kind of laboratory, unlike the ones we are accustomed to working in. With this in mind, Xerox has created a 1700 square-foot Color Systems Studio at the Xerox Webster Research Center. The Studio is designed to provide an environment in which researchers and customers can meet to coexplore the requirements for color documents in the workplace. Involving customers is a key feature of the studio and its investigations into the ecology of color documents. Creation of this new research environment is based on the premise that color documents cannot be separated from the context in which they are created and used. The Studio is a 'living' lab equipped with up-to-date computer platforms, networks and printers. This makes it possible to assemble complete document systems, from creation to printing, using a mix of commercially available and experimental equipment. In this environment, researchers can study not only the performance of individual components, but the work process itself. This paper will describe the reasoning that led to the creation of the Color Systems Studio and our early experiences with it.

    OpenStudio development efforts have been focused on providing Application Programming Interfaces (APIs) where users are able to extend OpenStudio without the need to compile the open source libraries. This paper will discuss the basic purposes and functionalities of the core libraries that have been wrapped with APIs including the Building Model, Results Processing, Advanced Analysis, UncertaintyQuantification, and Data Interoperability through Translators. Several building energy modeling applications have been produced using OpenStudio's API and Software Development Kits (SDK) including the United States Department of Energy's Asset ScoreCalculator, a mobile-based audit tool, an energy design assistance reporting protocol, and a portfolio scale incentive optimization analysismethodology. Each of these software applications will be discussed briefly and will describe how the APIs were leveraged for various uses including high-level modeling, data transformations from detailed building audits, error checking/quality assurance of models, and use of high-performance computing for mass simulations.

    This paper presents several case studies of rapidly implemented, audience-specific applications for whole building energy modeling and standards analysis. By tailoring each application to the audience and the task at hand, the required learning curve for new users was greatly reduced. Each case study used OpenStudio, the U.S. Department of Energy's middleware software development kit (SDK). OpenStudio provides an easy interface to the EnergyPlus whole building simulation engine, while extending its capability and providing higher-level functionality such as software interoperability, standards, analysis, and optimization. Each case study is unique in the technology employed to interface with OpenStudio as well as the methods used for user interaction and data presentation. Four case studies are presented.

    Kansas State University converted its introductory biology course, previously taught as an audio-tutorial (A-T), to a studio format in 1997. We share with others information about the process involved and present assessment data for the studio format course that address 1) student exam performance in A-T and studio; 2) student course grades in A-T and studio; 3) student and instructor perceptions and attitudes for A-T and studio; 4) student performance in subsequent biology courses for A-T and studio; and 5) gains in student learning for the studio course and other traditional lecture/lab courses. Collectively, these measures demonstrate that the studio format is as effective as or more effective (for some measures) than the A-T approach and traditional approaches in providing an effective learning environment. We discuss the issues involved in comparing course formats. PMID:18519615

    High-performance buildings require an integrated design approach for all systems to work together optimally; systems integration needs to be incorporated in the earliest stages of design for efforts to be cost and energy-use effective. Building designers need a full-featured software framework to support rigorous, multidisciplinary building simulation. An open source framework - the OpenStudio Software Development Kit (SDK) - is being developed to address this need. In this paper, we discuss the needs that drive OpenStudio's system architecture and goals, provide a development status report (the SDK is currently in alpha release), and present a brief case study that illustrates its utility and flexibility.

    The Colorado School of Mines (CSM) teaches its first-year calculus-based introductory physics courses (Physics I and Physics II) using a hybrid of lecture and Studio physics. This model was first implemented in Physics I in 1997, and was established in Physics II in the fall of 2007. In this talk, we highlight the stages of the transformation from traditional to Studio, highlighting what has worked and what has not, and describing methods for assessment and evaluation. Results suggest that Studio has increased student performance and satisfaction despite an aggressive expansion of class sizes in the past few years. Gains have been concentrated mostly in problem-solving skills and exam performance (as opposed to conceptual survey gains), in contrast to what has sometimes been seen in other studies. Most recently, we as a department have been capitalizing on our successes with Studio physics to take a leadership role in disseminating advanced educational methods throughout CSM, both vertically (into upper division physics courses) and horizontally (into various departments outside of physics). We will briefly describe progress so far.

  7. uVis Studio: an integrated development environment for visualization

    Pantazos, Kostas; Kuhail, Mohammad A.; Lauesen, Soren; Xu, Shangjin

    2013-01-01

    A toolkit facilitates the visualization development process. The process can be further enhanced by integrating the toolkits in development environments. This paper describes how the uVis toolkit, a formula-based visualiza- tion toolkit, has been extended with a development environment, called uVis Studio. Instead of programming, developers apply a Drag-Drop-Set-View-Interact approach. Developers bind controls to data, and the Studio gives immediate visual feedback in the Design Panel. This is a novel feature, called What-You-Bind-Is-What- You-Get. The Studio also provides Modes that allow developers to interact and view the visualization from the end-user's perspective without switching workspace, and Auto-Completion; a feature of the Property Grid that provides suggestions not only for the formula language syntax but also for the tables, the table elds and the relationships in the database. We conducted a usability study with six developers to evaluate if the Studio and its features enhance cognition and facilitate the visualization development. The results show that developers appreciated the Drag-Drop-Set- View-Interact approach, the What-You-Bind-Is-What-You-Get, the Auto-Completion and the Modes. Several usability problems were identified, and some suggestions for improvement include: new panels, better presentation of the Modes, and better error messages.

  11. A Framework for Daylighting Optimization in Whole Buildings with OpenStudio

    SciTech Connect

    2016-08-12

    We present a toolkit and workflow for leveraging the OpenStudio (Guglielmetti et al. 2010) platform to perform daylighting analysis and optimization in a whole building energy modeling (BEM) context. We have re-implemented OpenStudio's integrated Radiance and EnergyPlus functionality as an OpenStudio Measure. The OpenStudio Radiance Measure works within the OpenStudio Application and Parametric Analysis Tool, as well as the OpenStudio Server large scale analysis framework, allowing a rigorous daylighting simulation to be performed on a single building model or potentially an entire population of programmatically generated models. The Radiance simulation results can automatically inform the broader building energy model, and provide dynamic daylight metrics as a basis for decision. Through introduction and example, this paper illustrates the utility of the OpenStudio building energy modeling platform to leverage existing simulation tools for integrated building energy performance simulation, daylighting analysis, and reportage.

    OpenStudio is a free, open source Software Development Kit (SDK) and application suite for performing building energy modeling and analysis. The OpenStudio Parametric Analysis Tool has been extended to allow cloud-based simulation of multiple OpenStudio models parametrically related to a baseline model. This paper describes the new cloud-based simulation functionality and presents a model cali-bration case study. Calibration is initiated by entering actual monthly utility bill data into the baseline model. Multiple parameters are then varied over multiple iterations to reduce the difference between actual energy consumption and model simulation results, as calculated and visualized by billing period and by fuel type. Simulations are per-formed in parallel using the Amazon Elastic Cloud service. This paper highlights model parameterizations (measures) used for calibration, but the same multi-nodal computing architecture is available for other purposes, for example, recommending combinations of retrofit energy saving measures using the calibrated model as the new baseline.

    Sommario INTRODUZIONE: Valutare l'impatto diagnostico della Isterosonografia Tridimensionale (ISG 3D) nello studio della cavità uterina in donne con sanguinamento anomalo (SUA) rispetto all'ecografia transvaginale (ETV) e all'isterosonografia bidimensionale (ISG 2D), particolarmente per l'identificazione di neoformazioni a sviluppo endocavitario della superficie endometriale e della parete uterina. MATERIALI E METODI: Ventiquattro pazienti affette da SUA sono state incluse nello studio. Ciascuna di esse é stata sottoposta ad ETV, ISG e ISG 3D durante la medesima seduta. Le acquisizioni 3D sono state ottenute con tecnica free-hand in fase di massima replezione idrica della cavità. Tutte le pazienti sono state valutate con isteroscopia entro 10 giorni dall'ecografia. Considerando l'esame isteroscopico come reference standard, sono stati calcolati i valori di sensibilità, specificità, valore predittivo positivo (VPP), valore predittivo negativo (VPN) ed accuratezza delle tre metodiche. RISULTATI: L'isteroscopia ha dimostrato la presenza di lesioni endocavitarie in 21/24 pazienti (87,5%). Nelle restanti pazienti l'esame isteroscopico è risultato negativo. ETV, ISG 2D ed ISG 3D hanno mostrato rispettivamente sensibilità del 76% (16/21), 90% (19/21), 100% (21/21); specificità del 100% (3/3), 100% (19/19), 100% (21/21); VPP del 100%, 100%, 100%; VPN del 37%, 60%, 100%; accuratezza 76%, 90%, 100%. L'ISG 3D ha consentito una completa identificazione dei rapporti delle lesioni con la cavità uterina e con la parete endometriale. CONCLUSIONI: L'ISG 3D è una metodica con maggiore sensibilità nella definizione delle lesioni della cavità uterina rispetto all'ISG 2D ed all'ETV. Se questi dati preliminari saranno confermati da studi piú ampi, ISG 3D potrebbe essere proposta come alternativa all'isteroscopia eseguita a soli fini diagnostici.

    RIASSUNTO. Introduzione. La depressione maggiore (MD) e l'osteoporosi sono malattie ad alta prevalenza nel genere femminile, associate a morbosità e mortalità. Sebbene alcuni studi abbiano dimostrato un'associazione tra MD, ridotta densità minerale ossea (BMD) e osteoporosi, non sono stati chiariti i meccanismi causali. Lo stile di attaccamento insicuro è stato messo in relazione con la patogenesi e il decorso di malattie croniche come la MD e le malattie cardiovascolari. Obiettivo di questo studio pilota è esplorare la relazione tra MD e BMD. Si ipotizza che lo stile di attaccamento possa agire da mediatore. Metodi. Il campione è formato da 101 donne in menopausa, 49 con MD e 52 controlli sani. La diagnosi di MD è stata formulata con l'intervista clinica e la Beck Depression Inventory. Lo stile di attaccamento è stato esplorato usando il Relationship Questionnaire, la BMD con la Mineralometria Ossea Computerizzata con tecnica DXA (Dual energy X-ray Absorptiometry). Risultati. L'analisi univariata ha mostrato che le donne con MD avevano valori di BMD inferiori rispetto ai controlli sani. Nelle analisi di regressione multipla la MD non è emersa come predittore significativo di ridotta BMD. Lo stile di attaccamento insicuro "preoccupato" è risultato un predittore significativo di ridotta BMD in tutti i siti scheletrici misurati con la DXA: colonna vertebrale lombare (p=0,008) e segmenti femorali: "femoral neck" (p=0,011), "total hip" (p=0,002). Conclusioni. Questo è il primo studio che esplora il possibile ruolo di MD e stile di attaccamento sulla BMD. Lo stile di attaccamento è risultato un predittore di ridotta BMD, indipendentemente dalla MD. L'attaccamento insicuro potrebbe avere un ruolo nella patogenesi dell'osteoporosi anche indipendente dalla MD. Se questi risultati saranno confermati, gli interventi terapeutici focalizzati sullo stile di attaccamento potrebbero contribuire al miglioramento della comorbilità psichiatrica e medica legata all'osteoporosi.

  16. Presence of Staphylococcus aureus on university dance studio floors and barres: a preliminary investigation.

    PubMed

    Unsworth, Desiree A; Russell, Jeffrey A; Martiny, Adam C

    2014-01-01

    Staphylococcus aureus (S. aureus) is a bacterium associated with various infectious diseases. Not only has the bacterium been detected in sports environments, the reported incidences of S. aureus infections have steadily increased in athletic teams. However, in spite of similarities between sports and dance facilities, to our knowledge no previous study has examined the presence of this bacterium in the dance environment. We hypothesized that S. aureus would be present in a university's dance studios, and that it would be extant in higher concentrations inside versus outside the studios. Using common microbiological culturing methods, samples were gathered from floors and barres in three studios of a single university, as well as from outside floors and railings near the studios and a conference room used by dancers. Confirming our hypothesis, we detected S. aureus in every dance studio sample (0.03 to 0.38 cfu/cm 2 ). Supporting our second hypothesis, we found that average S. aureus concentrations from the three studios were significantly higher compared to both outside and conference room samples (P ≤ 0.001). The latter two locations did not yield any S. aureus concentrations. Control samples developed as expected. The results of this study suggest that S. aureus bacteria are common on the flooring and barres of university dance studios, with the bacterial concentrations possibly dependent on the hours of usage of these surfaces. Whether the presence of S. aureus in dance studios presents a health risk to dancers should be studied further.

  9. Arabidopsis CBF3 and DELLAs positively regulate each other in response to low temperature

    PubMed Central

    Zhou, Mingqi; Chen, Hu; Wei, Donghui; Ma, Hong; Lin, Juan

    2017-01-01

    The C-repeat binding factor (CBF) is crucial for regulation of cold response in higher plants. In Arabidopsis, the mechanism of CBF3-caused growth retardation is still unclear. Our present work shows that CBF3 shares the similar repression of bioactive gibberellin (GA) as well as upregulation of DELLA proteins with CBF1 and -2. Genetic analysis reveals that DELLAs play an essential role in growth reduction mediated by CBF1, -2, -3 genes. The in vivo and in vitro evidences demonstrate that GA2-oxidase 7 gene is a novel CBF3 regulon. Meanwhile, DELLAs contribute to cold induction of CBF1, -2, -3 genes through interaction with jasmonate (JA) signaling. We conclude that CBF3 promotes DELLAs accumulation through repressing GA biosynthesis and DELLAs positively regulate CBF3 involving JA signaling. CBFs and DELLAs collaborate to retard plant growth in response to low temperature. PMID:28051152

  11. A Pivotal Role of DELLAs in Regulating Multiple Hormone Signals.

    PubMed

    Davière, Jean-Michel; Achard, Patrick

    2016-01-04

    Plant phenotypic plasticity is controlled by diverse hormone pathways, which integrate and convey information from multiple developmental and environmental signals. Moreover, in plants many processes such as growth, development, and defense are regulated in similar ways by multiple hormones. Among them, gibberellins (GAs) are phytohormones with pleiotropic actions, regulating various growth processes throughout the plant life cycle. Previous work has revealed extensive interplay between GAs and other hormones, but the molecular mechanism became apparent only recently. Molecular and physiological studies have demonstrated that DELLA proteins, considered as master negative regulators of GA signaling, integrate multiple hormone signaling pathways through physical interactions with transcription factors or regulatory proteins from different families. In this review, we summarize the latest progress in GA signaling and its direct crosstalk with the main phytohormone signaling, emphasizing the multifaceted role of DELLA proteins with key components of major hormone signaling pathways.

  12. Exploring the Physics of Music with Temperament Studio

    NASA Astrophysics Data System (ADS)

    Durfee, Dallin; Colton, John

    2016-03-01

    The physics of waves, resonance, harmonics, and beats has determined how musical instruments are tuned, and has even affected the kinds of music written in different time periods. The laws of physics make it impossible for any fixed scale to have perfect consonance for all chords in all keys, and as a result, various musical scales, or temperaments, have been developed and used throughout history. The study of musical temperament is a rich application of wave physics. It ties several principles together in a context which can be very motivating for students. Furthermore, the topic is accessible to students in introductory classes. We have developed an open source application called Temperament Studio which allows students to explore musical temperament and to hear and measure the effects predicted by wave physics.

  13. OpenStudio: A Platform for Ex Ante Incentive Programs

    SciTech Connect

    Roth, Amir; Brackney, Larry; Parker, Andrew; Beitel, Annette

    2016-08-26

    Many utilities operate programs that provide ex ante (up front) incentives for building energy conservation measures (ECMs). A typical incentive program covers two kinds of ECMs. ECMs that deliver similar savings in different contexts are associated with pre-calculated 'deemed' savings values. ECMs that deliver different savings in different contexts are evaluated on a 'custom' per-project basis. Incentive programs often operate at less than peak efficiency because both deemed ECMs and custom projects have lengthy and effort-intensive review processes--deemed ECMs to gain confidence that they are sufficiently context insensitive, custom projects to ensure that savings are claimed appropriately. DOE's OpenStudio platform can be used to automate ex ante processes and help utilities operate programs more efficiently, consistently, and transparently, resulting in greater project throughput and energy savings. A key concept of the platform is the OpenStudio Measure, a script that queries and transforms building energy models. Measures can be simple or surgical, e.g., applying different transformations based on space-type, orientation, etc. Measures represent ECMs explicitly and are easier to review than ECMs that are represented implicitly as the difference between a with-ECM and without-ECM models. Measures can be automatically applied to large numbers of prototype models--and instantiated from uncertainty distributions--facilitating the large scale analysis required to develop deemed savings values. For custom projects, Measures can also be used to calibrate existing building models, to automatically create code baseline models, and to perform quality assurance screening.

    Ogni trattamento, medico e chirurgico, della paralisi facciale è finalizzato al recupero della simmetria facciale statica e dinamica. La tossina botulinica di tipo A può essere utilizzata nei pazienti affetti da paralisi del nervo facciale, sottoposti in precedenza a chirurgia primaria, al fine di ridurre la residua asimmetria facciale e le progressive ipercinesie controlaterali al lato affetto, che caratterizzano tali soggetti. Sono stati inclusi nel nostro studio sei pazienti (1 maschio e 5 femmine) affetti da paralisi del nervo facciale monolaterale secondaria a diverse cause, classificata secondo la scala di House-Brackmann in grado III e IV. I pazienti inclusi nello studio sono stati sottoposti in precedenza a trattamento chirurgico riabilitativo specifico per la paralisi facciale stessa; successivamente ciascuno di essi è stato trattato con 50 unità di tossina botulinica di tipo A a livello del lato non affetto del volto, al fine di ridurre le ipercinesie muscolari ed aumentare l’asimmetria e l’abilità muscolare del volto. L’età media dei soggetti era di 44,5 anni. I pazienti sono stati esaminati a 7, 14, 30, 60, 90 e 120 giorni dopo il trattamento con tossina botulinica. Lo studio dimostra la riduzione delle ipercinesie controlaterali alla paralisi facciale ed il miglioramento della simmetria del volto nei pazienti sottoposti precedentemente a trattamento chirurgico primario per la riabilitazione del nervo facciale stesso. Tutti i pazienti si sono dimostrati soddisfatti del trattamento con tossina botulinica di tipo A.

    RIASSUNTO. Scopo. I deficit delle funzioni esecutive (FE) sono frequentemente osservati nei disturbi dello spettro dell'autismo (ASD) e nel disturbo da deficit di attenzione con iperattività (ADHD). Lo scopo di questo studio è quello di valutare e confrontare le funzioni esecutive metacognitive ed emozionali/motivazionali di bambini con ASD e ADHD, sia fra di loro che con un gruppo di controllo. Metodi. Il campione è costituito da un totale di 58 soggetti, di cui 17 con ASD senza disabilità intellettiva, 18 con ADHD-manifestazione combinata e 23 con sviluppo tipico, abbinati per genere, età cronologica e livello intellettivo. Le valutazioni hanno riguardato alcune aree del funzionamento esecutivo, nello specifico pianificazione, flessibilità mentale, generatività e inibizione della risposta, che rappresentano sia le funzioni esecutive metacognitive sia quelle emozionali/motivazionali. Risultati. I risultati hanno rilevato un'ampia sovrapposizione delle disfunzioni esecutive nei due gruppi clinici con ASD e ADHD, e non sono stati indicativi della presenza di due profili realmente distinti del funzionamento esecutivo. Tuttavia, nell'ADHD è stato trovato un deficit più severo nell'inibizione della risposta prepotente (funzione emozionale/motivazionale). Conclusioni. I risultati del nostro studio sono parzialmente in accordo con quelli della letteratura. Ulteriori ricerche con gruppi più numerosi potranno chiarire più approfonditamente quali punti di forza e debolezza, nell'ampio spettro delle funzioni esecutive, differenzino fra loro le prestazioni di persone con ASD e ADHD.

  20. Maize DELLA proteins dwarf plant8 and dwarf plant9 as modulators of plant development.

    PubMed

    DELLA proteins are nuclear-localized negative regulators of gibberellin signaling found ubiquitously throughout higher plants. Dominant dwarfing mutations of DELLA proteins have been primarily responsible for the dramatic increases in harvest index of the 'green revolution'. Maize contains two genetic loci encoding DELLA proteins, dwarf plant8 (d8) and dwarf plant 9 (d9). The d8 gene and three of its dominant dwarfing alleles have been previously characterized at the molecular level. Almost 20 years after the initial description of the mutant, this investigation represents the first molecular characterization of d9 and its gibberellin-insensitive mutant, D9-1. We have molecularly, subcellularly and phenotypically characterized the gene products of five maize DELLA alleles in transgenic Arabidopsis. In dissecting the molecular differences in D9-1, a critical residue for normal DELLA function has been uncovered, corresponding to E600 of the D9 protein. The gibberellin-insensitive D9-1 was found to produce dwarfing and, notably, earlier flowering in Arabidopsis. Conversely, overexpression of the D9-1 allele delayed flowering in transgenic maize, while overexpression of the d9 allele led to earlier flowering. These results corroborate findings that DELLA proteins are at the crux of many plant developmental pathways and suggest differing mechanisms of flowering time control by DELLAs in maize and Arabidopsis.

  1. Uncovering DELLA-Independent Gibberellin Responses by Characterizing New Tomato procera Mutants.

    Gibberellin (GA) regulates plant development primarily by triggering the degradation/deactivation of the DELLA proteins. However, it remains unclear whether all GA responses are regulated by DELLAs. Tomato (Solanum lycopersicum) has a single DELLA gene named PROCERA (PRO), and its recessive pro allele exhibits constitutive GA activity but retains responsiveness to external GA. In the loss-of-function mutant pro(ΔGRAS), all examined GA developmental responses were considerably enhanced relative to pro and a defect in seed desiccation tolerance was uncovered. As pro, but not pro(ΔGRAS), elongation was promoted by GA treatment, pro may retain residual DELLA activity. In agreement with homeostatic feedback regulation of the GA biosynthetic pathway, we found that GA20oxidase1 expression was suppressed in pro(ΔGRAS) and was not affected by exogenous GA3. In contrast, expression of GA2oxidase4 was not affected by the elevated GA signaling in pro(ΔGRAS) but was strongly induced by exogenous GA3. Since a similar response was found in Arabidopsis thaliana plants with impaired activity of all five DELLA genes, we suggest that homeostatic GA responses are regulated by both DELLA-dependent and -independent pathways. Transcriptome analysis of GA-treated pro(ΔGRAS) leaves suggests that 5% of all GA-regulated genes in tomato are DELLA independent.

  7. DELLA proteins modulate Arabidopsis defences induced in response to caterpillar herbivory

    PubMed Central

    Bede, Jacqueline C.

    2014-01-01

    Upon insect herbivory, many plant species change the direction of metabolic flux from growth into defence. Two key pathways modulating these processes are the gibberellin (GA)/DELLA pathway and the jasmonate pathway. In this study, the effect of caterpillar herbivory on plant-induced responses was compared between wild-type Arabidopsis thaliana (L.) Heynh. and quad-della mutants that have constitutively elevated GA responses. The labial saliva (LS) of caterpillars of the beet armyworm, Spodoptera exigua, is known to influence induced plant defence responses. To determine the role of this herbivore cue in determining metabolic shifts, plants were subject to herbivory by caterpillars with intact or impaired LS secretions. In both wild-type and quad-della plants, a jasmonate burst is an early response to caterpillar herbivory. Negative growth regulator DELLA proteins are required for the LS-mediated suppression of hormone levels. Jasmonate-dependent marker genes are induced in response to herbivory independently of LS, with the exception of AtPDF1.2 that showed LS-dependent expression in the quad-della mutant. Early expression of the salicylic acid (SA)-marker gene, AtPR1, was not affected by herbivory which also reflected SA hormone levels; however, this gene showed LS-dependent expression in the quad-della mutant. DELLA proteins may positively regulate glucosinolate levels and suppress laccase-like multicopper oxidase activity in response to herbivory. The present results show a link between DELLA proteins and early, induced plant defences in response to insect herbivory; in particular, these proteins are necessary for caterpillar LS-associated attenuation of defence hormones.

  13. A consideration on physical tuning for acoustical coloration in recording studio

    NASA Astrophysics Data System (ADS)

    Shimizu, Yasushi

    2003-04-01

    Coloration due to particular architectural shapes and dimension or less surface absorption has been mentioned as an acoustical defect in recording studio. Generally interference among early reflected sounds arriving within 10 ms in delay after the direct sound produces coloration by comb filter effect over mid- and high-frequency sounds. In addition, less absorbed room resonance modes also have been well known as a major component for coloration in low-frequency sounds. Small size in dimension with recording studio, however, creates difficulty in characterization associated with wave acoustics behavior, that make acoustical optimization more difficult than that of concert hall acoustics. There still remains difficulty in evaluating amount of coloration as well as predicting its acoustical characteristics in acoustical modeling and in other words acoustical tuning technique during construction is regarded as important to optimize acoustics appropriately to the function of recording studio. This paper presents a example of coloration by comb filtering effect and less damped room modes in typical post-processing recording studio. And acoustical design and measurement technique will be presented for adjusting timbre due to coloration based on psycho-acoustical performance with binaural hearing and room resonance control with line array resonator adjusted to the particular room modes considered.

    2016-06-01

    This article describes a new open source scientific workflow system, the TimeStudio Project, dedicated to the behavioral and brain sciences. The program is written in MATLAB and features a graphical user interface for the dynamic pipelining of computer algorithms developed as TimeStudio plugins. TimeStudio includes both a set of general plugins (for reading data files, modifying data structures, visualizing data structures, etc.) and a set of plugins specifically developed for the analysis of event-related eyetracking data as a proof of concept. It is possible to create custom plugins to integrate new or existing MATLAB code anywhere in a workflow, making TimeStudio a flexible workbench for organizing and performing a wide range of analyses. The system also features an integrated sharing and archiving tool for TimeStudio workflows, which can be used to share workflows both during the data analysis phase and after scientific publication. TimeStudio thus facilitates the reproduction and replication of scientific studies, increases the transparency of analyses, and reduces individual researchers' analysis workload. The project website ( http://timestudioproject.com ) contains the latest releases of TimeStudio, together with documentation and user forums.

    2016-01-01

    Negli anni recenti in molti paesi europei si è dimostrata una crescente incidenza della pancreatite acuta (AP), ed alcuni studi indicano un aumento di rischio di AP nei pazienti diabetici. Questo studio è pertanto finalizzato a valutare il decorso clinico della AP nei pazienti diabetici. Sono stati studiati tutti i pazienti curati in reparto chirurgico per una diagnosi di AP identificando come pazienti diabetici quelli che all’anamnesi hanno confermato essere affetti da diabete di tipo 1 o di tipo 2 prima di essere ricoverati per AP. I pazienti ricoverati per AP, ed arruolati nello studio sono stati 963, e tra essi vi erano 87 (9%) diabetici. Tra questi ultimi erano più numerosi quelli portatori di calcolosi biliare quale causa della pancreatite (46% vs 32%). Nella maggioranza dei casi il decorso della AP è stato di gravità moderata, ma comunque nel 10,3% dei pazienti con diabete il decorso della malattia è stato moderatamente grave, e nel 12,7% decisamente grave. Non sono state osservate differenze nella mortalità da AP in entrambi i gruppi. Insufficienza sistemica è stata osservata più frequentemente nel gruppo dei diabetici di tipo 2 (5,4%) e 23,1% in quelli di tipo 2, a fronte del 5,1% dei pazienti non diabetici, con differenze statisticamente non significative. In conclusione l’incidenza della AP nei pazienti diabetici aumenta con l’età, ed è più spesso correlata con la calcolosi biliare. In questo gruppo di pazienti in decorso clinico è èiù frequentemente grave, con insufficienza sistemica nei diabetici di tipo 1.

  14. Mysteries of attraction: Giovanni Pico della Mirandola, astrology and desire.

    PubMed

    Rutkin, H Darrel

    2010-06-01

    Although in his later years Giovanni Pico della Mirandola (1463-1494) vehemently rejected astrology, he earlier used it in a variety of ways, but primarily to provide further evidence for positions to which he had arrived by other means. One such early use appears in his commentary on his friend Girolamo Benivieni's love poetry, the Canzone d'amore, of 1486-1487. In the passages discussed here, Pico presents an intensive Platonic natural philosophical analysis based on a deep astrologically informed understanding of human nature as he attempts to explain a perennial question, namely, why one person is attracted to a certain person (or people), and another to others. I will place this discussion of the mysteries of attraction and desire in historical perspective by tracing Pico's changing relationship to astrology during the course of his short but passionate life, and in historiographic perspective by revising Frances Yates's still influential views concerning Pico's contribution to Renaissance thought and his relationship with Marsilio Ficino.

  15. DELLA proteins regulate expression of a subset of AM symbiosis-induced genes in Medicago truncatula.

    The majority of the vascular flowering plants form symbiotic associations with fungi from the phylum Glomeromycota through which both partners gain access to nutrients, either mineral nutrients in the case of the plant, or carbon, in the case of the fungus. (1) The association develops in the roots and requires substantial remodeling of the root cortical cells where branched fungal hyphae, called arbuscules, are housed in a new membrane-bound apoplastic compartment. (2) Nutrient exchange between the symbionts occurs over this interface and its development and maintenance is critical for symbiosis. Previously, we showed that DELLA proteins, which are well known as repressors of gibberellic acid signaling, also regulate development of AM symbiosis and are necessary to enable arbuscule development. (3) Furthermore, constitutive overexpression of a dominant DELLA protein (della1-Δ18) is sufficient to induce transcripts of several AM symbiosis-induced genes, even in the absence of the fungal symbiont. (4) Here we further extend this approach and identify AM symbiosis genes that respond transcriptionally to constitutive expression of a dominant DELLA protein and also genes that do respond to this treatment. Additionally, we demonstrate that DELLAs interact with REQUIRED FOR ARBUSCULE DEVELOPMENT 1 (RAD1) which further extends our knowledge of GRAS factor complexes that have the potential to regulate gene expression during AM symbiosis.

  16. DELLA proteins are common components of symbiotic rhizobial and mycorrhizal signalling pathways

    Legumes form symbiotic associations with either nitrogen-fixing bacteria or arbuscular mycorrhizal fungi. Formation of these two symbioses is regulated by a common set of signalling components that act downstream of recognition of rhizobia or mycorrhizae by host plants. Central to these pathways is the calcium and calmodulin-dependent protein kinase (CCaMK)–IPD3 complex which initiates nodule organogenesis following calcium oscillations in the host nucleus. However, downstream signalling events are not fully understood. Here we show that Medicago truncatula DELLA proteins, which are the central regulators of gibberellic acid signalling, positively regulate rhizobial symbiosis. Rhizobia colonization is impaired in della mutants and we provide evidence that DELLAs can promote CCaMK–IPD3 complex formation and increase the phosphorylation state of IPD3. DELLAs can also interact with NSP2–NSP1 and enhance the expression of Nod-factor-inducible genes in protoplasts. We show that DELLA is able to bridge a protein complex containing IPD3 and NSP2. Our results suggest a transcriptional framework for regulation of root nodule symbiosis. PMID:27514472

    Legumes develop symbiotic interactions with rhizobial bacteria to form nitrogen-fixing nodules. Bacterial Nod factors (NFs) and plant regulatory pathways modulating NF signalling control rhizobial infections and nodulation efficiency. Here we show that gibberellin (GA) signalling mediated by DELLA proteins inhibits rhizobial infections and controls the NF induction of the infection marker ENOD11 in Medicago truncatula. Ectopic expression of a constitutively active DELLA protein in the epidermis is sufficient to promote ENOD11 expression in the absence of symbiotic signals. We show using heterologous systems that DELLA proteins can interact with the nodulation signalling pathway 2 (NSP2) and nuclear factor-YA1 (NF-YA1) transcription factors that are essential for the activation of NF responses. Furthermore, MtDELLA1 can bind the ERN1 (ERF required for nodulation 1) promoter and positively transactivate its expression. Overall, we propose that GA-dependent action of DELLA proteins may directly regulate the NSP1/NSP2 and NF-YA1 activation of ERN1 transcription to regulate rhizobial infections. PMID:27586842

    Regulation of plant height, one of the most important agronomic traits, is the focus of intensive research for improving crop performance. Stem elongation takes place as a result of repeated cell divisions and subsequent elongation of cells produced by apical and intercalary meristems. The gibberellin (GA) phytohormones have long been known to control stem and internodal elongation by stimulating the degradation of nuclear growth-repressing DELLA proteins; however, the mechanism allowing GA-responsive growth is only slowly emerging. Here, we show that DELLAs directly regulate the activity of the plant-specific class I TCP transcription factor family, key regulators of cell proliferation. Our results demonstrate that class I TCP factors directly bind the promoters of core cell-cycle genes in Arabidopsis inflorescence shoot apices while DELLAs block TCP function by binding to their DNA-recognition domain. GAs antagonize such repression by promoting DELLA destruction and therefore cause a concomitant accumulation of TCP factors on promoters of cell-cycle genes. Consistent with this model, the quadruple mutant tcp8 tcp14 tcp15 tcp22 exhibits severe dwarfism and reduced responsiveness to GA action. Altogether, we conclude that GA-regulated DELLA-TCP interactions in inflorescence shoot apex provide a novel mechanism to control plant height.

    Purpose The aim of this paper is to demonstrate fundamental photographic techniques and standardized views in oculoplastic disease and surgery outside of a photographic studio. Methods A Canon EOS 60D digital single lens reflex (DSLR) camera, which was fitted with a Canon EF-S 60 mm USM macro lens, was used to photograph the subject. A Canon MR-14EX Macro Ringlite was used to illuminate the subject. Informed written consent was obtained for publication of the photographs used in this study. The photographs were taken in an ophthalmology clinic using standardized photographic settings at various magnification ratios. The magnification ratios were recalibrated and adjusted to accommodate the smaller sensor size in-line with standardized medical photography guidelines. Results We present a series of core views for various oculoplastic and orbital disease presentations. Conclusions It is possible to capture quality standardized digital photographs in a busy clinical environment without the need for a dedicated photographic studio.

  1. Dynamic regulation of cortical microtubule organization through prefoldin-DELLA interaction.

    2013-05-06

    Plant morphogenesis relies on specific patterns of cell division and expansion. It is well established that cortical microtubules influence the direction of cell expansion, but less is known about the molecular mechanisms that regulate microtubule arrangement. Here we show that the phytohormones gibberellins (GAs) regulate microtubule orientation through physical interaction between the nuclear-localized DELLA proteins and the prefoldin complex, a cochaperone required for tubulin folding. In the presence of GA, DELLA proteins are degraded, and the prefoldin complex stays in the cytoplasm and is functional. In the absence of GA, the prefoldin complex is localized to the nucleus, which severely compromises α/β-tubulin heterodimer availability, affecting microtubule organization. The physiological relevance of this molecular mechanism was confirmed by the observation that the daily rhythm of plant growth was accompanied by coordinated oscillation of DELLA accumulation, prefoldin subcellular localization, and cortical microtubule reorientation.

    We explored the working methods of the Italian Baroque master Caravaggio through computer graphics reconstruction of his studio, with special focus on his use of lighting and illumination in The calling of St. Matthew. Although he surely took artistic liberties while constructing this and other works and did not strive to provide a "photographic" rendering of the tableau before him, there are nevertheless numerous visual clues to the likely studio conditions and working methods within the painting: the falloff of brightness along the rear wall, the relative brightness of the faces of figures, and the variation in sharpness of cast shadows (i.e., umbrae and penumbrae). We explored two studio lighting hypotheses: that the primary illumination was local (and hence artificial) and that it was distant solar. We find that the visual evidence can be consistent with local (artificial) illumination if Caravaggio painted his figures separately, adjusting the brightness on each to compensate for the falloff in illumination. Alternatively, the evidence is consistent with solar illumination only if the rear wall had particular reflectance properties, as described by a bi-directional reflectance distribution function, BRDF. (Ours is the first research applying computer graphics to the understanding of artists' praxis that models subtle reflectance properties of surfaces through BRDFs, a technique that may find use in studies of other artists.) A somewhat puzzling visual feature-unnoted in the scholarly literature-is the upward-slanting cast shadow in the upper-right corner of the painting. We found this shadow is naturally consistent with a local illuminant passing through a small window perpendicular to the viewer's line of sight, but could also be consistent with solar illumination if the shadow was due to a slanted, overhanging section of a roof outside the artist's studio. Our results place likely conditions upon any hypotheses concerning Caravaggio's working methods and

    The SCALE-UP studio physics class involves the physical redesign of a classroom to encourage more collaborative interactions and student-centered teaching, an approach shown to increase student learning on several different measures. However, research into the contextual issues involved in implementing a studio course using the SCALE-UP model remains limited. The research presented here explores the impact of situational factors on the implementation and maintenance of a research-based instructional innovation in a large research university. The specific focus of this investigation was the development and implementation of a studio version of an introductory physics course sequence at a large research university in the southeast United States using the SCALE-UP model. Interview, observation, and artifact data (including documents and Email conversations), collected over a period of two years, were analyzed. Using the Teacher Centered Systemic Reform framework, the data were analyzed to develop themes describing forces that both encouraged and restricted the growth of this studio course. Influential forces operated at the classroom, department, university, and broad cultural levels. The results demonstrate the importance of considering the specific nature of innovations implemented and their alignment with desired learning goals and outcomes. The importance of faculty collegiality emerges as a critical departmental force, as does administrative intervention at the department and university level. Broader, societal conversations related to improving undergraduate science education also provided important contextual framing for the change effort studied. The findings highlight important factors to contemplate when undertaking similar change efforts and recommendations from this study are offered for consideration.

  4. Piero della Francesca's Sky in The Dream of Constantine

    The recent restoration of the frescoes by Piero della Francesca in the Church of San Francesco in Arezzo has made to appear on the background of the scene of Constantine's dream a number of stars. They are clearly painted with the intention to illustrate a sort of "natural" sky. In 2001 Anna Maria Maetzke recognized in a group of stars the constellation of the Ursa Minor, but so far no further study has been carried on to find any relation between the painted and the true sky. In this paper I show the existence of more constellations in the fresco, which are hardly detectable due to the mirror representation of the starry sky. Such a mirror image, as the Universe was seen from the outside, has a Greek origin and this kind of representation was introduced in Western Europe not only in celestial globes but also in star maps. This discovery leads to consider that Piero had at his disposal either a globe or a map which he reproduced on the fresco. My hypothesis is that a star map might be supplied to Piero by the astronomer Regiomontanus who was in Italy since 1461 following the Cardinal Bessarion in his journey from Wien to Rome. In 1463, Cardinal Bessarion was named papal legate to Venice and in July of the same year he leaved Rome together with Regiomontanus to reach Ferrara and Venice. The road to Venice crossed Umbria nearby Sansepolcro, Piero's birthplace not far from Arezzo. The trip took more than two weeks due to a stop before crossing the Apennines because the plague in Ferrara. Bessarion and Regiomontanus might have met Piero who was painting the cycle of frescoes in Arezzo and supplied him with a star map. Unfortunately, due to the lack of the horizon and any right line in the scene it is not possible to detect the latitude of the place corresponding to the painted sky.

  5. The research-design interaction: lessons learned from an evidence-based design studio.

    As evidence-based design (EBD) emerges as a model of design practice, considerable attention has been given to its research component. However, this overshadows another essential component of EBD-the change agent, namely the designer. EBD introduced a new skill set to the practitioner: the ability to interact with scientific evidence. Industry sources suggest adoption of the EBD approach across a large number of design firms. How comfortable are these designers in integrating research with design decision making? Optimizing the interaction between the primary change agent (the designer) and the evidence is crucial to producing the desired outcomes. Preliminary to examining this question, an architectural design studio was used as a surrogate environment to examine how designers interact with evidence. Twelve students enrolled in a healthcare EBD studio during the spring of 2009. A three-phase didactic structure was adopted: knowing a hospital, knowing the evidence, and designing with knowledge and evidence. Products of the studio and questionnaire responses from the students were used as the data for analysis. The data suggest that optimization of the research-design relationship warrants consideration in four domains: (1) a knowledge structure that is easy to comprehend; (2) phase-complemented representation of evidence; (3) access to context and precedence information; and (4) a designer-friendly vocabulary.

    The concept of connected learning proposes that youth leverage individual interest and social media to drive learning with an academic focus. To illustrate, we present in-depth case studies of Ryan and Sam, two middle-school-age youth, to document an out-of-school intervention intended to direct toward intentional learning in STEM that taps interest and motivation. The investigation focused on how Ryan and Sam interacted with the designed elements of Studio STEM and whether they became more engaged to gain deeper learning about science concepts related to energy sustainability. The investigation focused on the roles of the engineering design process, peer interaction, and social media to influence youth interest and motivation. Research questions were based on principles of connected learning (e.g., self-expression, lower barriers to expertise, socio-technical supports) with data analyzed within a framework suggested by discursive psychology. Analyzing videotaped excerpts of interactions in the studio, field notes, interview responses, and artifacts created during the program resulted in the following findings: problem solving, new media, and peer interaction as designed features of Studio STEM elicited evidence of stimulating interest in STEM for deeper learning. Further research could investigate individual interest-driven niches that are formed inside the larger educational setting, identifying areas of informal learning practice that could be adopted in formal settings. Moreover, aspects of youth's STEM literacy that could promote environmental sustainability through ideation, invention, and creativity should be pursued.

    2017-01-01

    Fruit growth depends on highly coordinated hormonal activities. The phytohormone gibberellin (GA) promotes growth by triggering degradation of the growth-repressing DELLA proteins; however, the extent to which such proteins contribute to GA-mediated fruit development remains to be clarified. Three new plum genes encoding DELLA proteins, PslGAI, PslRGL and PslRGA were isolated and functionally characterized. Analysis of expression profile during fruit development suggested that PslDELLA are transcriptionally regulated during flower and fruit ontogeny with potential positive regulation by GA and ethylene, depending on organ and developmental stage. PslGAI and PslRGL deduced proteins contain all domains present in typical DELLA proteins. However, PslRGA exhibited a degenerated DELLA domain and subsequently lacks in GID1–DELLA interaction property. PslDELLA–overexpression in WT Arabidopsis caused dramatic disruption in overall growth including root length, stem elongation, plant architecture, flower structure, fertility, and considerable retardation in development due to dramatic distortion in GA-metabolic pathway. GA treatment enhanced PslGAI/PslRGL interaction with PslGID1 receptors, causing protein destabilization and relief of growth-restraining effect. By contrast, PslRGA protein was not degraded by GA due to its inability to interact with PslGID1. Relative to other PslDELLA–mutants, PslRGA–plants displayed stronger constitutive repressive growth that was irreversible by GA application. The present results describe additional complexities in GA-signalling during plum fruit development, which may be particularly important to optimize successful reproductive growth. PMID:28076366

    Obiettivo: Identificare le diagnosi infermieristiche ed i quadri teorici utilizzati nelle unità neonatali attraverso una revisione della letteratura. Metodo: Per effettuare questo studio sono stati usati database come Cinahl, Medline e Lilacs. I descrittori usati sono: "Diagnosi infermieristica" AND "Modelli, Infermieristici" OR "Teoria infermieristica" AND "Infante" OR "Neonato". La ricerca era limitata agli arti- coli pubblicati dal 2000 al novembre 2013. Venivano selezionati soltanto gli studi scritti in inglese, spagnolo, portoghese e italiano. Risultati: Nella revisione della letteratura sono state identificate due tassonomie e sei impor- tanti quadri teorici. Le diagnosi infermieristiche più frequentemente individuate sono: intol- leranza alle attività, ridotta ventilazione spontanea, modello di respirazione inefficace, rischio di aspirazione, ritardo nella crescita e nello sviluppo, allattamento al seno inefficace, modello di alimentazione infantile inefficace, ipertermia/ipotermia, rischio di infezione, alterazione dell’integrità cutanea, interruzione dei processi familiari, rischio di compromissione della genitorialità, rischio di riduzione dell’attaccamento. Sono state identificate diagnosi appli- cabili alla sfera psico-sociale genitoriale che consentivano una valutazione integrale del neonato, compresa la famiglia. Conclusioni: Le diagnosi infermieristiche consentono agli infermieri che lavorano nelle unità neonatali l’opportunità di gestire efficacemente il processo assistenziale, nonché la disponibilità dei dati necessari per il continuo miglioramento della qualità nella cura infer- mieristica. L'utilizzo di un unico modello o di più modelli di riferimento costituisce un modo per aiutare l'agire professionale.

  9. New reactions of germylenes with ketones and assessment of studio general chemistry

    NASA Astrophysics Data System (ADS)

    Sweeder, Ryan David

    New reaction modes of germylenes with ketones are presented. The germylene, Ge[CH(SiMe3)2]2 (1), will undergo reversible [4+2] addition with alkyl or aryl phenones to form a conjugated triene. Anthraquinone or 1,4-naphthylquinone will undergo a similar triene formation, but an insertion by a second molecule of 1 yields a product stable to reversion. In these cases, the second equivalent of germylene acts as a trap for the initially formed conjugated triene. A similar germylene, Ge[N(SiMe3)2]2 ( 2), reacts in analogous fashion with anthraquinone or 1,4-naphthylquinone indicating that it too engages in an equilibrium with phenones. The equilibrium for 2 with phenones lies heavily toward free 2 and phenone as no triene is detected via UV/Vis or NMR spectroscopies. Successful catalytic hydrogenation of the conjugate triene formed from the reaction of 1 with benzophenone is also presented. Other non-phenone ketones react with 1 via either CH or OH insertion. Three acetyl-containing ketones (acetone, butanone and cyclopropyl methyl ketone) have been observed to undergo CH insertion with 1 in the presence of one equivalent of MgCl2. The absence of MgCl 2 yields apparent OH insertion into the enol tautomer of the ketone. All secondary ketones examined undergo OH insertion even in the presence of MgCl2. The development, assessment and a description of a studio version of general chemistry are presented. This new course was implemented in the Fall 2002 semester at the University of Michigan. Content-based interviews focusing on equilibrium indicated that the students from the studio course had a better understanding of the underlying principles of equilibrium than their non-studio counterparts. The students enrolled in the studio course also gave more non-prompted explanations for a chemical reaction demonstrated during the interview, suggesting that they were more capable of transferring their chemical knowledge to new systems.

    The DELLA family of transcription regulators functions as master growth repressors in plants by inhibiting phytohormone gibberellin (GA) signaling in response to developmental and environmental cues. DELLAs also play a central role in mediating cross-talk between GA and other signaling pathways via antagonistic direct interactions with key transcription factors. However, how these crucial protein–protein interactions can be dynamically regulated during plant development remains unclear. Here, we show that DELLAs are modified by the O-linked N-acetylglucosamine (O-GlcNAc) transferase (OGT) SECRET AGENT (SEC) in Arabidopsis. O-GlcNAcylation of the DELLA protein REPRESSOR OF ga1-3 (RGA) inhibits RGA binding to four of its interactors—PHYTOCHROME-INTERACTING FACTOR3 (PIF3), PIF4, JASMONATE-ZIM DOMAIN1, and BRASSINAZOLE-RESISTANT1 (BZR1)—that are key regulators in light, jasmonate, and brassinosteroid signaling pathways, respectively. Consistent with this, the sec-null mutant displayed reduced responses to GA and brassinosteroid and showed decreased expression of several common target genes of DELLAs, BZR1, and PIFs. Our results reveal a direct role of OGT in repressing DELLA activity and indicate that O-GlcNAcylation of DELLAs provides a fine-tuning mechanism in coordinating multiple signaling activities during plant development.

    The DELLA family of transcription regulators functions as master growth repressors in plants by inhibiting phytohormone gibberellin (GA) signaling in response to developmental and environmental cues. DELLAs also play a central role in mediating cross-talk between GA and other signaling pathways via antagonistic direct interactions with key transcription factors. However, how these crucial protein-protein interactions can be dynamically regulated during plant development remains unclear. Here, we show that DELLAs are modified by the O-linked N-acetylglucosamine (O-GlcNAc) transferase (OGT) SECRET AGENT (SEC) in Arabidopsis.

    The project Exploring Science in the Studio at California College of the Arts (CCA), one of the oldest and most influential art and design schools in the country, pursues ways to enable undergraduate students to become scientifically literate problem-solvers in a variety of careers and to give content and context to their creative practices. The two main branches of this National Science Foundation-funded project are a series of courses called Science in the Studio (SitS) and the design of the Mobile Units for Science Exploration (MUSE) system, which allow instructors to bring science equipment directly into the studios. Ongoing since 2010, each fall semester a series of interdisciplinary SitS courses are offered in the college's principal areas of study (architecture, design, fine arts, humanities and sciences, and diversity studies) thematically linked by Earth and environmental science topics such as water, waste, and sustainability. Each course receives funding to embed guest scientists from other colleges and universities, industry, or agriculture directly into the studio courses. These scientists worked in tandem with the studio faculty and gave lectures, led field trips, conducted studio visits, and advised the students' creative endeavors, culminating in an annual SitS exhibition of student work. The MUSE system, of fillable carts and a storage and display unit, was designed by undergraduate students in a Furniture studio who explored, experimented, and researched various ways science materials and equipment are stored, collected, and displayed, for use in the current and future science and studio curricula at CCA. Sustainable practices and "smart design" underpinned all of the work completed in the studio. The materials selected for the new Science Collection at CCA include environmental monitoring equipment and test kits, a weather station, a stream table, a rock and fossil collection, and a vertebrate skull collection.

    Medical photography is an important part of the medical file and is widely used in medical communication, especially in our discipline. His practice has to be the most standardized and reproducible as possible, which distinguishes it from artistic photography. Photography fix the light reflecting from a subject, so surgeon have to control of the light source in any environment. In the absence of dedicated studio, using external cobra or ring flashes with special diffusers allow the surgeon to have light sources adapted to the different conditions encountered in daily practice.

In this system, ArcGIS SDE9.1 is applied as the spatial data engine, and the system was a synthetic management software developed with Visual Studio visualization procedures development tools. As the pipeline update function of the system has the phenomenon of slower update and even sometimes the data lost, to ensure the underground pipeline data can real-time be updated conveniently and frequently, and the actuality and integrity of the underground pipeline data, we have increased a new update module in the system developed and researched by ourselves. The module has the powerful data update function, and can realize the function of inputting and outputting and rapid update volume of data. The new developed module adopts Visual Studio visualization procedures development tools, and uses access as the basic database to storage data. We can edit the graphics in AutoCAD software, and realize the database update using link between the graphics and the system. Practice shows that the update module has good compatibility with the original system, reliable and high update efficient of the database.

    The development of a cross-platform, programmable integrated development environment (IDE), MeTA Studio, specifically tailored but not restricted to computational chemists working in the area of quantum chemistry with an emphasis on handling large molecules is presented. The IDE consists of a number of modules which include a visualizer and a programming and collaborative framework. The inbuilt viewer assists in visualizing molecules, their scalar fields, manually fragmenting a molecule, and introduces some innovative but simple techniques for handling large molecules. These include a simple Find language and simultaneous multiple camera views of the molecule. Basic tools needed to handle collaborative computing effectively are also included opening up new vistas for sharing ideas and information among computational chemists working on similar problems. MeTA Studio is an integrated programming environment that provides a rich set of application programming interfaces (APIs) which can be used to easily extend its functionality or build new applications as needed by the users.

    High stress is a prevalent problem in the worksite. To reduce stress, improve productivity, reduce absenteeism, and lower healthcare costs, many companies offer exercise classes or stress management programmes. Although physical activity is an important component of stress management, few worksites have integrated physical activity into their comprehensive stress reduction programmes. The purpose of this single-arm pilot project was to examine the potential effectiveness of an integrated exercise (studio cycling) and cognitive-behavioural stress management programme. Eighty-four adults, 75% female, mostly aged 40+ years, participated in an integrated 12-week cycling studio and cognitive-behavioural stress management programme. Participants experienced a significant and clinically meaningful reduction on the Perceived Stress Scale (p < 0.01), rating of current stress level and confidence to manage stress at the programme's end and at a 1-month follow-up. Participants also reported having significantly improved overall health, improved nutritional habits, higher physical activity level, greater confidence in their ability to follow a healthy diet, higher spiritual well-being, improved sleep, receiving more support for maintaining healthy living and improved quality of life at the completion of the 12-week programme and 1-month follow-up. These findings provide further support for an integrated exercise and stress management programme.

    Fox Studios partnered with the U.S. Department of Energy (DOE) to develop and implement solutions to retrofit two production stages and one of its central cooling plants, to reduce energy consumption by at least 30% as part of DOE’s Commercial Building Partnerships (CBP) Program. Although this case study reports expected savings arising from proposed design recommendations for a unique building type and the unusual load characteristics associated with its use, the EEMs implemented for the central plant are applicable to any large campus, office and higher education facility. The intent is that by making the energy-efficiency measures (EEMs) set that were assessed as cost-effective from this project applicable to a larger number of buildings on the campus Fox Studios will be able to implement an integrated campus-wide energy strategy for the long term. The significant challenges for this project in the design phase included identifying how to assess and analyze multiple system types, develop a coherent strategy for assessment and analysis, implement the measurement and verification activities to collect the appropriate data (in terms of capturing ‘normal’ operating characteristics and granularity) and determine the best approach to providing cooling to the site buildings based on the nature of existing systems and the expected improvement in energy performance of the central cooling plant. The analytical framework adopted provides a blueprint for similar projects at other large commercial building campuses.

    Introduzione. Attualmente sono pochi gli studi che indagano la capacità empatica nella popolazione infermieristica. Obiettivo di questo studio è analizzare la capacità empatica degli infermieri che prestano servizio in area medica in relazione a genere, età, formazione e anzianità di servizio. Materiali e metodi. Lo studio è di tipo descrittivo-osservazionale, su un campione di 60 infermieri. Lo strumento utilizzato per la valutazione dell’empatia è la scala di valutazione JSPE (versione HP) costituita da 20 item, in cui gli intervistati indicano il loro accordo o disaccordo con una scala Likert a 7 punti. Il range di valori possibili è da 20 a 140: il punteggio più alto corrisponde a una maggiore capacità empatica. Il questionario ha dimostrato la validità e l'affidabilità della versione italiana del JSPE con un coefficiente alfa di Cronbach di 0,85. Il punteggio Il livello di significatività statistica accettato è pari a P ≤ 0,05. Risultati. La media della capacità empatica dei professionisti intervistati è risultata di 104/140. Dai dati analizzati, emerge che con l’aumentare degli anni di servizio alla professione si verifica una diminuzione dell’empatia così come il permanere nello stesso reparto provoca una diminuzione empatica. Inoltre è emersa una maggiore empatia degli infermieri della neurologia rispetto alla medicina generale. Conclusioni. Lo studio evidenzia come i professionisti abbiano necessità di incrementare la capacità empatica soprattutto col trascorrere degli anni di esercizio alla professione. Probabilmente come meccanismo di difesa, il professionista tende a proteggersi dal coinvolgimento emotivo, favorendo le attività di natura più tecnico-gestuale, piuttosto che relazionale.

  10. The DELLA Protein SLR1 Integrates and Amplifies Salicylic Acid- and Jasmonic Acid-Dependent Innate Immunity in Rice1

    Gibberellins are a class of tetracyclic plant hormones that are well known to promote plant growth by inducing the degradation of a class of nuclear growth-repressing proteins, called DELLAs. In recent years, GA and DELLAs are also increasingly implicated in plant responses to pathogen attack, although our understanding of the underlying mechanisms is still limited, especially in monocotyledonous crop plants. Aiming to further decipher the molecular underpinnings of GA- and DELLA-modulated plant immunity, we studied the dynamics and impact of GA and DELLA during infection of the model crop rice (Oryza sativa) with four different pathogens exhibiting distinct lifestyles and infection strategies. Opposite to previous findings in Arabidopsis (Arabidopsis thaliana), our findings reveal a prominent role of the DELLA protein Slender Rice1 (SLR1) in the resistance toward (hemi)biotrophic but not necrotrophic rice pathogens. Moreover, contrary to the differential effect of DELLA on the archetypal defense hormones salicylic acid (SA) and jasmonic acid (JA) in Arabidopsis, we demonstrate that the resistance-promoting effect of SLR1 is due at least in part to its ability to boost both SA- and JA-mediated rice defenses. In a reciprocal manner, we found JA and SA treatment to interfere with GA metabolism and stabilize SLR1. Together, these findings favor a model whereby SLR1 acts as a positive regulator of hemibiotroph resistance in rice by integrating and amplifying SA- and JA-dependent defense signaling. Our results highlight the differences in hormone defense networking between rice and Arabidopsis and underscore the importance of GA and DELLA in molding disease outcomes. PMID:26829979

    Experimental results have shown that the high harmonic fast wave (HHFW) at 30 MHz can provide substantial plasma heating and current drive for the NSTX spherical tokamak operation. However, the present antenna strap design rarely achieves the design goal of delivering the full transmitter capability of 6 MW to the plasma. In order to deliver more power to the plasma, a new antenna strap design and the associated coaxial line feeds are being constructed. This new antenna strap design features two feedthroughs to replace the old single feed-through design. In the design process, CST Microwave Studio has been used to simulate the entire new antenna strap structure including the enclosure and the Faraday shield. In this paper, the antenna strap model and the simulation results will be discussed in detail. The test results from the new antenna straps with their associated resonant loops will be presented as well.

    Third spaces are in-between places where teacher-student scripts intersect, creating the potential for authentic interaction and a shift in what counts as knowledge. This paper describes a unique community-university initiative: a third space storefront classroom for postsecondary students in professional education programs, which also functions as a community art studio for the surrounding neighborhood. This approach to professional education requires an innovative combination of theory, methods, and materials as enacted by the professionals involved and performed by the students. This storefront classroom utilizes collaborative and inclusive instructional practices that promote human and community development. It facilitates the use of innovative instructional strategies including art making and participatory dialogue to create a liminal learning space that reconfigures professional education. In researching the effectiveness of this storefront classroom, we share the voices of students who have participated in this third space as part of their coursework to underscore these principles and practices.

    As part of the NAHB Research Center Industry Partnership, Southface partnered with TaC Studios, an Atlanta-based architecture firm specializing in residential and light commercial design, on the construction of a new test home in Atlanta, GA, in the mixed humid climate. This home serves as a residence and home office for the firm's owners, as well as a demonstration of their design approach to potential and current clients. Southface believes the home demonstrates current best practices for the mixed-humid climate, including a building envelope featuring advanced air sealing details and low density spray foam insulation, glazing that exceeds ENERGY STAR requirements, and a high performance heating and cooling system. Construction quality and execution was a high priority for TaC Studios and was ensured by a third party review process. Post-construction testing showed that the project met stated goals for envelope performance, an air infiltration rate of 2.15 ACH50. The homeowners wished to further validate whole house energy savings through the project's involvement with Building America and this long-term monitoring effort. As a Building America test home, this home was evaluated to detail whole house energy use, end use loads, and the efficiency and operation of the ground source heat pump and associated systems. Given that the home includes many non-typical end use loads including a home office, pool, landscape water feature, and other luxury features not accounted for in Building America modeling tools, these end uses were separately monitored to determine their impact on overall energy consumption.

    Negli ultimi anni, alcuni chirurghi hanno cercato di rendere sempre meno invasiva la procedura della colecistectomia videolaparoscopica, riducendo il calibro degli strumenti. Nel nostro studio si vogliono dimostrare i vantaggi nell’utilizzo di strumenti miniaturizzati (con diametro di 3mm), comparandoli con la colecistectomia laparoscopica realizzata con strumenti da 5mm. I parametri analizzati nello studio sono: la durata dell’intervento, la durata della degenza, il dolore postoperatorio, le complicanze ed il risultato estetico. Lo studio si basa su una casistica personale di 114 pazienti trattati in un periodo di 12 mesi. Tutti i pazienti sono stati trattati per calcolosi sintomatica della colecisti o per poliposi della colecisti. In 102 pazienti si è trattato di colecistectomia minilaparoscopica e in 12 colecistectomia laparoscopica con strumenti da 5mm o perchè presentavano un eccessivo spessore delle pareti della colecisti che rendeva difficoltosa la presa sull’organo con strumenti di 3mm, o perchè presentavano calcoli lungo la via biliare principale e si rendeva quindi necessario eseguire una colangiografia intraoperatoria. L’esecuzione della tecnica minilaparoscopica richiede particolari accorgimenti per superare piccole difficoltà tecniche in rapporto alla maggiore flessibilità degli stumenti di ridotto calibro e all’impossibilità di applicare clips metalliche con i trocars da 3mm. E’ necessario legare con filo di sutura il dotto cistico mediante nodi intracorporei e coagulare l’arteria cistica con corrente monopolare. La durata dell’intervento risulta in media di 47 minuti per la colecistectomia con strumenti da 5mm e di 50 minuti per la colecistectomia minilaparoscopica. La degenza media è stata di 49 ore per la colecistectomia con strumenti da 5mm e di 18 ore per la colecistectomia minilaparoscopica; 73 pazienti sono stati dimessi lo stesso giorno dell’intervento. Il dolore post operatorio è risultato inferiore nei pazienti

Per raccogliere i dati riguardanti le ossa temporali sono stati inclusi nello studio 241 pazienti (482 ossa temporali) che hanno ricevuto una Tomografia Computerizzata a alta risoluzione (HRCT) dell'orecchio nel nostro Policlinico Universitario tra il 2003 e il 2008; i pazienti sono stati divisi in 3 Gruppi: 97 (194 orecchie) aventi una ipoacusia neurosensoriale severa o profonda bilaterale (Gruppo A), 70 (140 orecchie) aventi una ipoacusia neurosensoriale moderata bilaterale (Gruppo B), 74 pazienti (148 orecchie) senza ipoacusia neurosensoriale o mista (gruppo C). In ciascuno dei 3 gruppi, sono stati identificati 5 sottogruppi in base all'età: 1) sottogruppo 1: soggetti ≤ 5 anni, 2) sottogruppo 2: soggetti da 6 a 10 anni; 3) sottogruppo 3: pazienti da 11 a 15 anni, 4) sottogruppo 4: pazienti da 16 a 20 anni, 5) sottogruppo 5: soggetti >; 20 anni. Sono stati misurati la lunghezza della coclea (L), l'altezza della coclea (H), il diametro del lume del giro basale (BTLD) e il Volume della coclea (V). Il Test di Mann-Whitney è stato utilizzato per verificare l'ipotesi alternativa che a livello di queste dimensioni esiste una differenza statisticamente significativa tra i differenti gruppi e sottogruppi.

    KEY MESSAGE : We reported the cloning of a rose DELLA gene. We obtained transgenic Pelargonium lines overexpressing this gene which presented several phenotypes in plant growth, root growth, flowering time and number of inflorescences. Control of development is an important issue for production of ornamental plant. The plant growth regulator, gibberellins (GAs), plays a pivotal role in regulating plant growth and development. DELLA proteins are nuclear negative regulator of GA signalling. Our objective was to study the role of GA in the plant architecture and in the blooming of ornamentals. We cloned a rose DELLA homologous gene, RoDELLA, and studied its function by genetic transformation of pelargonium. Several transgenic pelargonium (Pelargonium × domesticum 'Autum Haze') lines were produced that ectopically expressed RoDELLA under the control of the 35S promoter. These transgenic plants exhibited a range of phenotypes which could be related to the reduction in GA response. Most of transgenic plants showed reduced growth associated to an increase of the node and branch number. Moreover, overexpression of RoDELLA blocked or delayed flowering in transgenic pelargonium and exhibited defects in the root formation. We demonstrated that pelargonium could be used to validate ornamental gene as the rose DELLA gene. RoDELLA overexpression modified many aspects of plant developmental pathways, as the plant growth, the transition of vegetative to floral stage and the ability of rooting.

Ninety hospitals in various Italian Regions participated. 916 cases of acute myocardial infarction with no history of ischaemic heart disease and 1106 controls admitted to hospital for acute conditions not related to known or suspected risk factors for ischaemic heart disease were studied. Relative risks (RR) and 95% confidence intervals (CI) of myocardial infarction according to various measures of tobacco smoking, were adjusted for identified potential confounding factors using multiple logistic regression. Compared to lifelong non-smokers, the RR was 1.3 (95% CI 1.0 to 1.9) for ex-smokers, 2.0 (95% CI 1.4 to 2.9) for current smokers of less than 15 cigarettes per day, 3.1 (95% CI 2.2 to 4.2) for 15-24 cigarettes per day and 4.9 (95% CI 3.4 to 7.1) for 25 or more cigarettes per day. No trend in risk was evident for the duration, the RR being around 3 for subsequent categories. There was a significant interaction between smoking and age. Below the age 45, smokers of 25 or more cigarettes per day had a 33 times higher risk than non-smokers, compared to 7.5 at in the age group 45-54, 4.4 between the ages 55-64 and 2.5 at the age of 65 or over. The risk estimates were higher in women (RR for > or = 25 cigarettes per day = 10.1), in subjects in the lowest cholesterol tertile (RR = 11.9), with no history of diabetes (RR = 6.8), hypertension (RR = 9.5), no family history ischaemic heart disease (RR = 9.1) and low body mass index (RR = 9.3). The importance of smoking is confirmed as a cause of acute myocardial infarction: about 50% of all nonfatal infarctions in this Italian population could be attributable to cigarette smoking.(ABSTRACT TRUNCATED AT 250 WORDS)

    The relationship between frequency of consumption of eleven indicator foods (milk, meat, liver, carrots, green vegetables, fruit, eggs, ham, fish, cheese and alcohol) and serum cholesterol was investigated in the comparison group of a case-control study of acute myocardial infarction conducted in Italy. Data were collected on 792 subjects from various Italian regions, admitted to hospital for acute conditions unrelated to any known or potential risk factor for myocardial infarction or to long-term modifications in diet. No statistically or epidemiologically meaningful relationship emerged between serum cholesterol level and frequency of consumption of any of these foods. Cholesterol levels rose according to increasing consumption tertiles for most of the indicator foods considered. Higher values for the higher tertile of consumption were observed for meat, ham and eggs, but also for fruit, carrots and green vegetables. However, correlation coefficients between frequency of consumption of various food items and serum cholesterol level were uniformly low for all food items considered, ranging between -0.09 (for milk) and 0.19 (for ham). Although a more comprehensive diet history may lead to different indications, the present data are not suggestive of any major influence of long-term frequency of consumption of a few selected indicator foods on serum cholesterol levels.

    The relationship between physical activity and acute myocardial infarction (AMI) was examined in a case-control study conducted in Italy in 1988 to 1989 within the framework of the GISSI-2 trial of streptokinase versus alteplase and heparin versus no heparin in the treatment of AMI. A total of 916 case patients admitted to coronary care units from various Italian regions for AMI were interviewed. Control subjects were 1106 patients admitted to the same network of hospitals for a broad spectrum of acute diseases not related to known or potential risk factors for myocardial infarction. Among various types of physical activity (occupational activity, walking, stair climbing, and sport and leisure-time physical activity), occupational physical exercise emerged as the most protective. Multivariate odds ratios (ORs) were 1.4 (95% confidence interval (CI), 1.0 to 2.0) and 1.6 (95% CI, 1.2 to 2.1) for the two lowest levels of occupational physical activity. The trends of increasing risk with decreasing activity were consistent, although less strong, when other types of activity were considered. The protection conveyed by occupational physical activity was similar across various strata of sex, age, education, smoking habits, and diabetes, and was not explained by serum cholesterol, body weight, or hypertension. This study therefore confirms that low physical activity is an indicator of subsequent risk of AMI.

    The relationship between coffee consumption and acute myocardial infarction (AMI) was analyzed using data from a case-control study conducted in 1988 to 1989 within the framework of the GISSI-2 trial on streptokinase versus alteplase and heparin versus no heparin in the treatment of AMI. A total of 801 male patients with AMI and 792 control subjects who were hospitalized in several Italian regions for diseases unrelated to known or potential risk factors for cardiovascular diseases were included. Compared with coffee nondrinkers, the multivariate relative risks (RRs), after allowance for age, education, body mass index, smoking habits, alcohol consumption, family history of AMI, cholesterol level, history of diabetes, and hypertension, were 0.8 (95% confidence interval (CI), 0.5 to 1.2) for consumption of one cup/d, 1.3 (95% CI, 0.9 to 2.0) for two cups/d, 1.8 (95% CI, 1.1 to 2.7) for three cups, 2.5 (95% CI, 1.5 to 4.1) for four cups, and 2.6 (95% CI, 1.6 to 4.2) for five cups or more. The trend in risk with dose was statistically significant (P < 0.001). Duration of coffee consumption was not associated with the risk of AMI. The RRs for daily coffee consumption were elevated across strata of various covariates, including age, smoking habits, cholesterol level, diabetes, and hypertension, with a particularly elevated (although not significantly heterogeneous) estimate in patients younger than 50 years (RR, 5.7; 95% CI, 3.0 to 10.9 for four or more cups/d). The RR in patients who drank four or more cups of coffee per day and were current smokers was 8.1 (95% CI, 5.1 to 13.0), suggesting an unfavorable effect on the combination of cigarette smoking and high coffee intake on the risk of AMI.

    One hundred and sixty-nine severely demented patients were tested in a multicenter study with the short version of the Severe Impairment Battery which was translated into Italian with the purpose of adapting and validating it for an Italian population. Patients were enrolled in Italian geriatric centers participating in the Study Group on Aging Brain of the Italian Society of Gerontology and Geriatrics. Following thorough clinical and instrumental examinations, they were evaluated with the Mini Mental State Examination, the Clinical Dementia Rating, the Severe Impairment Battery (SIB), the Gottfries-Bråne-Steen Rating Scale for Dementia, the Activity of Daily Living index, and the Bedford Alzheimer Nursing Severity scale (BANS.s). The inter-rater reliability of the SIB was highly significant for the total score and its subtests; test-retest reliability showed the same significance in all items. Also concurrent validity, performed comparing the total SIB score with the total BANS.s score, was significant. The short Italian version of the SIB proved to be a very reliable tool for the evaluation of severely demented patients; it has the advantage of being easy to administer, it evaluates more cognitive domains that, are typically assessed in dementia, and has a wide enough range of scores to detect even small differences in the examined abilities.

    Dissemination of Della Robbia glazed terracotta in the Marche (Italy) region started from the third decade of the 16th century. Numerous altarpieces, some of which no longer exist, document this artistic production. The protagonists of this diffusion phase were two of Andrea Della Robbia's sons, Marco (Fra Mattia) and Francesco (Fra Ambrogio). This paper shows the results of the scientific investigations carried out on constitutive materials of different altarpieces located in South Marche belonging to the Fra Mattia's production: the Coronation of Virgin between Saints Rocco, Sebastian, Peter martyr and Antonio abbot, dated back to 1527-1530, located in the collegiate church of S. Maria Assunta in Montecassiano; the Annunciation, dated back to 1520, placed in the church of S. Maria del Soccorso in Arcevia; the fragmentary Crowned Madonna and saints altarpiece, probably realized after 1531, today preserved in Civic Museum of Ripatransone. The first altarpiece was made in Montecassiano using two different assembling or production techniques: the external part of the lunette and the pillar strips are made of glazed polychrome terracotta, while the altar step and the internal part are an interesting and uncommon example of polychrome painted terracotta. The provenance of the glazed Arcevia altarpiece is not clear yet: some historians hypothesize a local manufacture of Fra Mattia and some others a Roman or Florentine production. The remaining parts of Ripatransone altarpiece are partially glazed and partially not coated perhaps because they were unfinished and not yet painted. Clay body samples collected from the above mentioned altarpieces were investigated using different analytical techniques (OM, XRD, XRF, PIXE) to point out differences in chemical and mineralogical composition and to determine if the altarpieces were made by using local raw clay materials or other clays from Tuscany or Campania as in the Della Robbia previous production. A comparison has also been

    This article reports on an exploratory research project to evaluate the usefulness or otherwise of real-time visual feedback in the singing studio. The primary purpose of the work was not to optimize the technology for this application, but to work alongside teachers and students to study the impact of real-time visual feedback technology use on the students' learning experiences. An action research methodology was used to explore the benefit of real-time displays over an extended period. The experimental phase of the work was guided by a Liaison Panel of teachers and academics in the areas of singing, pedagogy, voice science, speech therapy, and linguistic science. Qualitative data were collected from eight students working with two professional singing teachers. The teachers and students acted as co-researchers under the action research paradigm. Teachers and students alike kept journals of their teaching and learning experiences. Singing lessons were observed regularly by the research team, coded for teacher and student behaviors, and all co-researchers were interviewed at the mid- and endpoint of the project. The use of technology had a positive impact on the learning process, and this is evidenced through case study data.

    An observational study of 2 years was promoted by the Italian Association for Cutaneous Ulcers (AIUC) in order to monitor the epidemiology of leg ulcers, the trend of healing and the more frequent therapeutic approaches in lower limb ulcers. Fifty-nine sites in 14 different Italian regions involved in the study, with 1333 enrolled patients (1163 patients fully evaluated and followed up for 9 months). A prevalence of females (62%) was observed with a mean age of 70 years and a high rate of hypertension (62%), diabetes (38%) and obesity (29%). Venous ulcer was most frequent (55%), followed by mixed (25%) and diabetic (8·3%) ulcers. Basically, all patients received a local therapy (LT) (compression and advanced local therapies), while 63% of patients have an associated systemic pharmaceutical treatment. Ulcer healing rates progressively increased throughout the study and despite the type of observational study does not allow conclusions on the treatment, it was observed that the patients receiving additional systemic drugs were associated with a more rapid acceleration of healing rates of ulcers compared to LT alone (3 months: 39·7% versus 29·2%; 6 months: 62·0% versus 47·0%; 9 months: 74·7% versus 63·8%). In particular, the Studio Ulcere Vascolari (SUV) study showed that a combination treatment with sulodexide and compression therapy allows for a greater increase in the healing rates in venous ulcers.

    Digital cameras are of increasing significance for professional applications in photo studios where fashion, portrait, product and catalog photographs or advertising photos of high quality have to be taken. The eyelike is a digital camera system which has been developed for such applications. It is capable of working online with high frame rates and images of full sensor size and it provides a resolution that can be varied between 2048 by 2048 and 6144 by 6144 pixel at a RGB color depth of 12 Bit per channel with an also variable exposure time of 1/60s to 1s. With an exposure time of 100 ms digitization takes approx. 2 seconds for an image of 2048 by 2048 pixels (12 Mbyte), 8 seconds for the image of 4096 by 4096 pixels (48 Mbyte) and 40 seconds for the image of 6144 by 6144 pixels (108 MByte). The eyelike can be used in various configurations. Used as a camera body most commercial lenses can be connected to the camera via existing lens adaptors. On the other hand the eyelike can be used as a back to most commercial 4' by 5' view cameras. This paper describes the eyelike camera concept with the essential system components. The article finishes with a description of the software, which is needed to bring the high quality of the camera to the user.

    As part of the NAHB Research Center Industry Partnership, Southface partnered with TaC Studios, an Atlanta-based architecture firm specializing in residential and light commercial design, on the construction of a new test home in Atlanta, GA in the mixed humid climate. This home serves as a residence and home office for the firm's owners, as well as a demonstration of their design approach topotential and current clients. Southface believes the home demonstrates current best practices for the mixed-humid climate, including a building envelope featuring advanced air sealing details and low density spray foam insulation, glazing that exceeds ENERGY STAR requirements, and a high performance heating and cooling system. Construction quality and execution was a high priority for TaCStudios and was ensured by a third party review process. Post-construction testing showed that the project met stated goals for envelope performance, an air infiltration rate of 2.15 ACH50. The homeowners wished to further validate whole house energy savings through the project's involvement with Building America and this long-term monitoring effort. As a Building America test home, this homewas evaluated to detail whole house energy use, end use loads, and the efficiency and operation of the ground source heat pump and associated systems. Given that the home includes many non-typical end use loads including a home office, pool, landscape water feature, and other luxury features not accounted for in Building America modeling tools, these end uses were separately monitored todetermine their impact on overall energy consumption.

    Paladino, Laura C.

    A pilgrim on the trails of the Earth: that's how Gerbertus appears to us in the years preceding his pontificate as well in those, brief and intense, in which he was Pope. An ardent pilgrim of faith moved at the same time by vast intellectual interests that allowed him to come into contact with the most important schools of the time, of any cultural tradition; a pilgrim full of love, willing to transmit the enormous heritage of faith and knowledge of which he was custodian. The presence of the illustrious Benedictine is not explicitly documented in the Abbey of San Michele della Chiusa, but the signs of its cultural and ideological influence are evident both in historical memory as in the artistical vestiges of the Sacra: we investigate here, this presence, authoritative, original and versatile, to outline another aspect, still little investigated, of the lesson of Gerbert, monk, scientist, teacher and pastor.

    The electromagnetic field simulation software package CST MICROWAVE STUDIO (MWS) was used to compute the cold-test parameters - frequency-phase dispersion, on-axis impedance, and attenuation - for a traveling-wave tube (TWT) slow-wave circuit. The results were compared to experimental data, as well as to results from MAFIA, another three-dimensional simulation code from CST currently used at the NASA Glenn Research Center (GRC). The strong agreement between cold-test parameters simulated with MWS and those measured experimentally demonstrates the potential of this code to reduce the time and cost of TWT development.

    Sommario INTRODUZIONE: La fisiologia articolare dell’articolazione temporo-mandibolare (ATM) può essere esaminata sia dal punto di vista clinico che strumentale. La diagnostica per immagini ha da tempo contribuito con la risonanza magnetica (RM) e anche con la radiografia (Rx) e la tomografia computerizzata (TC) all’analisi della morfologia dei capi articolari e della cinetica condilare. L’esame duplex-ecodoppler è una metodica di largo impiego nello studio delle strutture in movimento in particolar modo a livello delle strutture del sistema vascolare. MATERIALI E METODI: È stata utilizzata un’apparecchiatura Toshiba APLIO SSA-770A, con l’uso di tecnica duplex-ecodoppler multi display, che consente la visualizzazione contemporanea dell’immagine ecografica e dei segnali Doppler utilizzando una sonda lineare del tipo phased array con cristalli trasduttori funzionanti ad una frequenza fondamentale di 6 MHz per gli spettri Doppler pulsati e 7.5 MHz per l’imaging ecografico. Sono stati esaminati nel Dipartimento di Scienze Radiologiche, Oncologiche e Anatomo-patologiche dell’Università “Sapienza” di Roma, 30 pazienti del reparto di Ortognatodonzia dell’Istituto di Odontoiatria della stessa Università. RISULTATI: Nei pazienti normali si è ottenuta un’alternanza regolare degli spettri Doppler, mentre nei soggetti con disfunzioni del complesso condilo-meniscale, si è persa la regolarità della sommatoria degli spettri di Fourier, con altezze incostanti in relazione a spostamenti irregolari del complesso condilo-meniscale. CONCLUSIONI: L’esame ecodoppler si è dimostrato, in tutti i pazienti, capace di discriminare quelli normali dai patologici e tra questi ultimi ha permesso di identificare gli aspetti più significativi delle patologie disfunzionali.

    As an independent satellite campus, The University of Michigan-Flint (UM-Flint) is a typical, small four-year, primarily undergraduate, institution, having just passed an enrollment of 8000 students in fall 2011. Astronomy courses are offered under the physics program, which itself is part of the Department of Computer Science, Engineering, and Physics. In this poster, we present a timeline for how astronomy course offerings have evolved from four separate lecture/lab courses to a single survey-style class. We plan to offer this survey course in a studio model inspired by our introductory physics courses. This presents a format that is manageable by a small program with very limited resources and also makes use of learning strategies that have been successful in teaching introductory physics. We present some of these proposed learning strategies and invite community input on potential changes and avenues for improvement. In addition to the new studio format for the course, the university also leases time from the local planetarium. We present a sample of the labs that utilize the unique environment of the planetarium, and associated learning goals.

    The estimation of genetic linkage maps is a key component in plant and animal research, providing both an indication of the genetic structure of an organism and a mechanism for identifying candidate genes associated with traits of interest. Because of this importance, several computational solutions to genetic map estimation exist, mostly implemented as stand-alone software packages. However, the estimation process is often largely hidden from the user. Consequently, problems such as a program crashing may occur that leave a user baffled. THREaD Mapper Studio (http://cbr.jic.ac.uk/threadmapper) is a new web site that implements a novel, visual and interactive method for the estimation of genetic linkage maps from DNA markers. The rationale behind the web site is to make the estimation process as transparent and robust as possible, while also allowing users to use their expert knowledge during analysis. Indeed, the 3D visual nature of the tool allows users to spot features in a data set, such as outlying markers and potential structural rearrangements that could cause problems with the estimation procedure and to account for them in their analysis. Furthermore, THREaD Mapper Studio facilitates the visual comparison of genetic map solutions from third party software, aiding users in developing robust solutions for their data sets.

    La Torre dei Venti domina l’angolo Sud Ovest del cortile della Pigna (nell'area dei Musei Vaticani), ed è inclusa negli ambienti dell'Archivio Segreto Vaticano. Non è aperta al pubblico, ma è universalmente nota per la fama che da oltre quattrocento anni la circonda, legata alle vicende della riforma Gregoriana del calendario. La meridiana tracciata da padre Egnazio Danti (1536-1586) nella torre dei Venti, fu visitata anche da Gregorio XIII, probabilmente il 21 marzo 1581 come suppone il padre Stein, per convincersi dell'anticipo ormai arrivato a dieci giorni dell'equinozio di primavera sulla data che il concilio di Nicea aveva fissato al 21 marzo per il computo pasquale. La ricognizione astrometrica del febbraio-marzo 2009 fatta dall'autore viene qui presentata.

    Considerata la necessità di elaborare un sistema di rotazione nei reparti di Chirurgia che venga incontro alle necessità degli studenti, abbiamo ideato questo studio prospettico presso la Facoltà di Medicina e Psicologia di “Sapienza, Università di Roma”. Nella nostra Istituzione, gli studenti del terzo anno del corso di laurea di Medicina e Psicologia trascorrono un periodo di 2 mesi presso il reparto di Chirurgia Generale per prepararsi all’esame di Semeiotica Medico-Chirurgica. Spesso i feedback di tale esperienza riportano una certa insoddisfazione, soprattutto per la scarsità dell’attività pratica al letto del paziente. Pertanto, abbiamo deciso di confrontare cinque modelli per stabilire il migliore approccio in termini di apprendimento e soddisfazione degli studenti. 28 studenti sono stati coinvolti nello studio e divisi in cinque gruppi (da A ad E). Il Gruppo A ha eseguito una rotazione standard così come prevista dall’ordine degli studi, 5 accessi in reparto seguiti dal proprio tutor. Gli studenti del gruppo B hanno frequentato il reparto una volta la settimana, arrivando dopo la visita della mattina, trascorrendo un’ora con il tutor ed il resto della mattina con gli specializzandi. Il gruppo C è stato diviso in piccoli gruppi, ciascuno assegnato per 2 volte all’ambulatorio chirurgico, 2 volte in reparto (standard) e 2 volte al servizio di preospedalizzazione. Gli studenti del gruppo D hanno frequentato il reparto una volta la settimana arrivando la mattina presto, trascorrendo 2 ore con il tutor ed il resto della mattina con gli specializzandi. Il gruppo E è stato diviso in 2 gruppi, ciascuno assegnato 3 volte al reparto (standard) e 3 volte alla sala operatoria. Ciascuno studente ha completato un questionario con 20 item di semeiotica all’inizio ed alla fine dello studio per valutare la progressione dell’apprendimento, ed un questionario finale di valutazione della soddisfazione. I risultati hanno dimostrato come tutti i gruppi

    Cangrande della Scala, Prince of Verona (Italy), died suddenly shortly after his triumph in the battle of Treviso (July 18, 1329). Thus, in the frame of a multidisciplinary paleo-pathological study, we carried out a multielemental analysis on the Prince's tissue specimens, including hair, liver, muscle, and bone, in order to characterize a multitissue profile of metallic elements in a nobleman of the 14th century. Biological specimens were analyzed by inductively coupled plasma-mass spectrometry. We were able to rule out arsenic poisoning as the primary cause of death. High levels of gold and silver in both hair and liver samples were probably due to prolonged contact of the mummy with precious metals in the funeral garments. High lead concentrations in both liver and bone tissue can be traced back to the ingestion of contaminated food and alcoholic beverages. Most of the essential elements were in the normal range of values for contemporary living people. The low arsenic and chromium levels in the Prince's tissues as compared to modern people would be suggestive of raised concentrations of both the elements in the present era, which are likely due to industrial pollution.

    Cellulose, which can be converted into numerous industrial products, has important impacts on the global economy. It has long been known that cellulose synthesis in plants is tightly regulated by various phytohormones. However, the underlying mechanism of cellulose synthesis regulation remains elusive. Here, we show that in rice (Oryza sativa), gibberellin (GA) signals promote cellulose synthesis by relieving the interaction between SLENDER RICE1 (SLR1), a DELLA repressor of GA signaling, and NACs, the top-layer transcription factors for secondary wall formation. Mutations in GA-related genes and physiological treatments altered the transcription of CELLULOSE SYNTHASE genes (CESAs) and the cellulose level. Multiple experiments demonstrated that transcription factors NAC29/31 and MYB61 are CESA regulators in rice; NAC29/31 directly regulates MYB61, which in turn activates CESA expression. This hierarchical regulation pathway is blocked by SLR1-NAC29/31 interactions. Based on the results of anatomical analysis and GA content examination in developing rice internodes, this signaling cascade was found to be modulated by varied endogenous GA levels and to be required for internode development. Genetic and gene expression analyses were further performed in Arabidopsis thaliana GA-related mutants. Altogether, our findings reveal a conserved mechanism by which GA regulates secondary wall cellulose synthesis in land plants and provide a strategy for manipulating cellulose production and plant growth.

    At the beginning of the twentieth century, the Italian cytologist Paolo Della Valle developed a theory of instable chromosomes (teoria dei cromosomi labili). He radically criticized the so-called Sutton-Boveri hypothesis (Martins and Martins, Genetics and Molecular Biology, 22:261-271, 1999), focusing on numerical constancy in the species and individuality. On the basis of bibliographical review and personal observations, he maintained that the chromosomes were neither stable bodies, nor permanent structures, but transitory cellular materials, resulting from the periodical rearrangement of the chromatin during the cell division. German and English-speaking biologists reacted. The paper shows some content of the argumentations used by Thomas H. Montgomery and especially Edmund B. Wilson. The discussion was characterized by the same data which is interpretedby different scholars in different ways. And the point is that no one of them had the decisive test to demonstrate his own point of view. Wilson simply invoked on his behalf a certain 'common sense', defending at least a 'high degree of constancy'. The debate waned along with the reception of Morgan's chromosome theory of heredity, but only the advent of molecular biology definitively stated the nature of chromosomes as permanent structures of the cell.

    RIASSUNTO. La schizofrenia colpisce circa l'1% della popolazione e rappresenta un grave disturbo mentale con un notevole impatto anche sul funzionamento sociale, lavorativo e sulle attività della vita quotidiana. Le persone con schizofrenia hanno un tasso di mortalità superiore di 2-2,5 rispetto a quello della popolazione generale. La non aderenza ai farmaci antipsicotici è uno dei più importanti fattori di rischio per le ricadute e le ospedalizzazioni, sia nei pazienti con disturbo cronico sia al primo episodio, e conseguentemente contribuisce all'aumento dei costi sanitari. Gli antipsicotici atipici LAI possono migliorare l'aderenza al trattamento contribuendo a diminuire i tassi di ricaduta nei pazienti affetti da schizofrenia fin dall'esordio. Gli obiettivi primari nella gestione dei pazienti schizofrenici sono diretti, non solo alla riduzione dei sintomi nel breve termine, ma anche al mantenimento fisico e della funzionalità mentale, migliorando la qualità della vita e promuovendo il recupero del paziente. Scopo. Proporre un modello integrato, basato sulle evidenze, che fornisca un algoritmo efficace per il recupero del paziente schizofrenico e indagare l'efficacia e la sicurezza degli antipsicotici LAI nel trattamento, nel mantenimento, nella prevenzione delle ricadute e nella recovery dei pazienti affetti da schizofrenia. Metodi. Dopo un'accurata analisi di letteratura abbiamo identificato, raccolto e analizzato gli elementi qualificanti per un'ottimale gestione del paziente schizofrenico, definendo un modello di gestione e selezione delle alternative terapeutiche. Conclusioni. Il modello di gestione della schizofrenia proposto potrebbe consentire un migliore recupero funzionale del paziente grazie alla scelta di iniziare il percorso terapeutico, fin dalle prime fasi del disturbo soprattutto se in giovane età e al primo episodio, con un farmaco atipico LAI. All'interno dei farmaci antipsicotici atipici la formulazione LAI rappresenta una scelta

    In the past decade, academic screening centers have been created in many universities worldwide. Most of these screening centers are organized as core facilities that accept projects from both within their organization and from external users in order to maximize staff and instrument usage. The Max Planck Institute of Molecular Cell Biology and Genetics in Dresden, Germany, also created such a screening facility named the Technology Development Studio (TDS). The mission of the facility is to provide cell based screening services focused on high resolution confocal imaging. The acquisition of high resolution images allows the mathematical description of cells with image analysis to a high degree of precision. This precision in turn allows classifying phenotypes accurately and compare different cellular treatments to discover underlying mechanisms.

    Sommario INTRODUZIONE: La ricchezza della componente vascolare dei tumori ginecologici influenza le caratteristiche dell'imaging diretto, utilizzando metodiche che evidenziano la componente macrovascolare delle lesioni (color e power Doppler), e di quello indiretto, mediante somministrazione di mezzi di contrasto (MdC) per lo studio del microcircolo e della perfusione interstiziale. Lo scopo di questo lavoro è di valutare l'aggiunta di informazioni diagnostiche fornite dalla valutazione ecografica con MdC nello studio delle lesioni ovariche. MATERIALI E METODI: Abbiamo valutato 72 lesioni annessiali in 61 pazienti con lesioni ovariche di incerta interpretazione mediante somministrazione di 4,8 ml di MdC ecoamplificatore di II generazione. Per ogni lesione, abbiamo valutato la morfologia basale, quella contrastografica e le curve intensità/tempo. RISULTATI: La valutazione post-contrasto confrontata con la basale non ha apportato informazioni aggiuntive morfovascolari in 8 pazienti (13,1%); in 38 pazienti (62,3%) ha apportato informazioni senza modifiche del comportamento clinico; in 15 soggetti (24,6%) ha apportato elementi che hanno modificato il comportamento clinico. Le lesioni maligne presentavano valori di tempo massimo di enhancement significativamente minori (11,9 ± 3,1 s vs 19,8 ± 4,0 s p < 0,01) e intensità di picco massimo significativamente maggiore (24,7 ± 4,2 dB vs 17,8 ± 3,3 dB p < 0,01) rispetto alle lesioni benigne. CONCLUSIONI: La CEUS consente di migliorare la confidenza diagnostica nelle lesioni liquide corpuscolate in cui l'indagine convenzionale non risulta dirimente, proponendosi nella diagnosi differenziale di un limitato numero di lesioni complesse, in alternativa a TC ed RM. Le informazioni ottenute influenzano tuttavia il successivo iter diagnostico e terapeutico in una limitata percentuale di casi (24,6%).

    Diego Velázquez's Las meninas (1656) has been called by some art experts "the most important painting of the 17th century," "a theology of painting," and even "the world's greatest painting"; it has been the subject of intensive study. The work depicts a complex scene in the Alcázar palace of King Philip IV of Spain, and includes mirror reflections of the king and queen, apparently standing in place of the viewer, as well as the artist himself standing before an enormous canvas on an easel. Nevertheless, questions remain about the studio and the proper viewing configuration: Is the artist looking toward the perspectivally correct position of the viewer in the museum space (center of projection), outside the picture space? Does the perspectivally correct position correspond to the locations of the king and queen seen reflected in the mirror? Is the bright illumination on the king and queen (as revealed in the mirror) consistent with the lighting in the tableau itself? We addressed these questions in a new way: by building a full computer graphics model of the figures and tableau as well as the viewer's space outside the painting. In our full model, the painting itself is represented as a translucent window onto which the picture space is projected toward the center of projection, that is, the viewer. Our geometric and (new) lighting evidence confirm Janson's and Snyder's contention that the plane mirror on the back wall reflects the other side of the large painting depicted within the tableau, not the king and queen themselves in the studio. We believe our computer graphics synthesis of both the tableau within the painting and the viewer's space in the real world is the first of its kind to address such problems in the history of art.

    A new active learning introductory gemology studio course with a lab component has been created at Queensborough Community College with the support of NSF TUES grant. Various pedagogical techniques that have shown efficacy at 4-year colleges have been implemented and adopted to improve student learning and course retention as well as to stimulate their interest in science and in STEM careers. The course covered broad range of STEM topics central to the gemology curriculum, including concepts from geology, mineralogy, physics and chemistry. Lectures and labs were linked. Students' misconceptions were addressed via guided laboratory activities in a studio-learning environment. The course used peer-based learning and problem solving by creating student groups that discussed observations and measurements. Discussion groups were required to observe, synthesize, and evaluate data for presentations. The goal was to empower student learning and peer-based teaching and to recruit early career, often non-STEM students, to earth science. Students were often prompted to engage in self-reflections on their learning. In this presentation we will present the analysis of the evaluation of the course and its impact on community college students. Some of the evaluation tools we have used are pre- and post- knowledge surveys, science attitude and belief surveys as well as a Geological Interest instrument. Parallel sections of traditionally taught lecture-only courses (taught by the same instructor) were utilized as a control group in the analysis. The pedagogical implications of the analysis on instruction and course design will be discussed as well.

    As part of the NAHB Research Center Industry Partnership, Southface partnered with TaC Studios, an Atlanta based architecture firm specializing in residential and light commercial design, on the construction of a new test home in Atlanta, GA in the mixed-humid climate. This home serves as a residence and home office for the firm's owners, as well as a demonstration of their design approach to potential and current clients. Southface believes the home demonstrates current best practices for the mixed-humid climate, including a building envelope featuring advanced air sealing details and low density spray foam insulation, glazing that exceeds ENERGY STAR requirements, and a high performance heating and cooling system. Construction quality and execution was a high priority for TaC Studios and was ensured by a third party review process. Post construction testing showed that the project met stated goals for envelope performance, an air infiltration rate of 2.15 ACH50. The homeowner's wished to further validate whole house energy savings through the project's involvement with Building America and this long-term monitoring effort. As a Building America test home, this home was evaluated to detail whole house energy use, end use loads, and the efficiency and operation of the ground source heat pump and associated systems. Given that the home includes many non-typical end use loads including a home office, pool, landscape water feature, and other luxury features not accounted for in Building America modeling tools, these end uses were separately monitored to determine their impact on overall energy consumption.

    In 2012 a manuscript was rediscovered in the Biblioteca dell'Archiginnasio of Bologna, titled Libro degli infermi dell'Arciconfraternita di S. Maria della Morte. It is the record of incoming patients of one for the main hospitals of the city, devoted exclusively to the sick poor and not just to the poor, called Santa Maria della Morte, compiled by a young student assistant (astante) for the period 1558-1564. I publish here a transcription of a portion of this Libro pertaining to the year 1560. My introduction situates the manuscript within the context of the history of early modern Italian hospitals, describes the organization of the hospital of Santa Maria della Morte based on archival sources of the period, and finally highlights the connections between surgical and anatomical education and the internal organization of the hospital.

    The phytohormone gibberellin (GA) has long been known to regulate the growth, development, and life cycle progression of flowering plants. However, the molecular GA-GID1-DELLA mechanism that enables plants to respond to GA has only recently been discovered. In addition, studies published in the last few years have highlighted previously unsuspected roles for the GA-GID1-DELLA mechanism in regulating growth response to environmental variables. Here, we review these advances within a general plant biology context and speculate on the answers to some remaining questions. We also discuss the hypothesis that the GA-GID1-DELLA mechanism enables flowering plants to maintain transient growth arrest, giving them the flexibility to survive periods of adversity.

    This study examines the geochemical and mineralogical variations in the ferruginous mineralisations that crop out within Grotta della Monaca, which is considered to be the most striking and best known example of a prehistoric iron mine-cave from the southern Apennines (Calabria, Italy). Previous archaeological research identified three local and distinct ancient exploitation phases of these ferruginous mineralisations: (1) an Upper Palaeolithic phase; (2) a Late Neolithic phase; and (3) a post-Medieval phase. These materials, which have various forms of complex mineralogical admixtures and range in colour from yellow-orange to red and darker brown shades, mainly consist of iron oxides/hydroxides (essentially goethite and lepidocrocite), which are often mixed with subordinate and variable amounts of other matrix components (carbonates, sulphates, arsenates, silicates and organic matter). Such ferruginous mineralisations generally correspond to geochemically heterogeneous massive dyke/vein/mammillary/stratiform facies that are exposed within the local caves along open fractures and inclined bedding planes and that partially cover cave wall niches/notches/pockets and ceiling cupolas/holes. Selected samples/sub-samples are analysed through a multi-technique approach with a handheld portable X-ray Fluorescence, X-ray Diffraction, micro-Raman and Fourier Transform Infrared spectroscope (both conventional and attenuated total reflection), which is combined with subsequent multivariate statistical analysis of the elemental concentration data. The geochemical and mineralogical results are used to individualise similar compositional clusters. As expected, the identified groups, each of which has very specific geochemical-mineralogical "fingerprints" and spatial distributions, enable us to identify the sampled ferruginous mineralisations. These specific mineral resources can be compared to similar raw materials that are found in other neighbouring archaeological sites, with

    The Monte della Stella is a 1131~m high mountain, belonging to the range separating the Alento Valley from the Tyrrhenian Sea, south of the city of Agropoli in Italy. At 1030~m over the sea-level, a large, isolated outcrop of the bedrock is present. This rock is well known to local people and called the ``Preta 'ru Mulacchio'', expression meaning in the local dialect ``The Bastard Child Rock''. The ``Preta'' is basically composed by three rocks that were originated along of natural reasons from a single block of arenite in its upper part and of a rough conglomerate in the lower one: between the three rocks, two galleries (thereafter F and G) were thus formed. However, it is easy to see that the ``Preta'' was deeply modified by human intervention: large stones were wedged in exact position between the three original blocks or positioned as a cover. We found that F gallery has an astronomical azimuth of 359 deg and G gallery of 240 deg. Inside the measurement precision (1 deg), the galleries are thus respectively oriented to the meridian and to the sunset of the winter solstice. Furthermore, modern folklore associated to the rock seems to remind very ancient fertility rites. From a statistical analysis of the alignments and an archaeological study of the complex, we conclude that ``Preta 'ru Mulacchio'' is most probably a monument, dated to an epoch presently unknown but possibly preceding the Greek colonization of Cilento, built in order to determine with a high precision the winter solstice because of cerimonial reasons, probably connected with fertility rites.

    Plants protect themselves from the harmful effects of pathogens by resistance and tolerance. Disease resistance, which eliminates pathogens, can be modulated by bacterial type III effectors. Little is known about whether disease tolerance, which sustains host fitness with a given pathogen burden, is regulated by effectors. Here, we examined the effects of the Xanthomonas effector protein XopDXcc8004 on plant disease defenses by constructing knockout and complemented Xanthomonas strains, and performing inoculation studies in radish (Raphanus sativus L. var. radiculus XiaoJinZhong) and Arabidopsis plants. XopDXcc8004 suppresses disease symptoms without changing bacterial titers in infected leaves. In Arabidopsis, XopDXcc8004 delays the hormone gibberellin (GA)-mediated degradation of RGA (repressor of ga1-3), one of five DELLA proteins that repress GA signaling and promote plant tolerance under biotic and abiotic stresses. The ERF-associated amphiphilic repression (EAR) motif-containing region of XopDXcc8004 interacts with the DELLA domain of RGA and might interfere with the GA-induced binding of GID1, a GA receptor, to RGA. The EAR motif was found to be present in a number of plant transcriptional regulators. Thus, our data suggest that bacterial pathogens might have evolved effectors, which probably mimic host components, to initiate disease tolerance and enhance their survival.

    Vegetation and climate during the last ice age and the Last Glacial Maximum (LGM, ∼23,000-19,000 cal BP) were considerably different than during the current interglacial (Holocene). Cold climatic conditions and growing ice-sheets during the last glaciation radically reduced forest extent in Europe to a restricted number of so-called ;refugia;, mostly located in the southern part of the continent. On the basis of paleobotanical analyses the Euganian Hills (Colli Euganei) in northeastern Italy have previously been proposed as one of the northernmost refugia of temperate trees (e.g. deciduous Quercus, Tilia, Ulmus, Fraxinus excelsior, Acer, Abies alba, Fagus sylvatica, Carpinus and Castanea) in Europe. In this study we provide the first quantitative, vegetation independent summer air temperature reconstruction for Northern Italy spanning the time ∼31,000-17,000 cal yr BP, which covers the coldest periods of the last glacial, including the LGM and Heinrich stadials 1 to 3. Chironomids preserved in a lake sediment core from Lago della Costa (7m a.s.l.), a small lake at the south-eastern edge of the Euganean Hills, allowed quantitative reconstruction of Full and Late Glacial summer air temperatures using a combined Swiss-Norwegian temperature inference model based on chironomid assemblages from 274 lakes. Chironomid and pollen evidence from Lago della Costa derives from finely stratified autochthonous organic gyttja sediments, which excludes major sediment mixing or reworking. After reconstructing paleo-temperatures, we address the question whether climate conditions were warm enough to permit the local survival of temperate tree species during the LGM and whether local expansions and pollen-inferred contractions of temperate tree taxa coincided with chironomid-inferred climatic changes. Our results suggest that chironomids at Lago della Costa have responded to major climatic fluctuations such as temperature decreases during the LGM and Heinrich stadials. The

    "I CAMMINI DELLA REGINA" (The Via Regina Paths) is an Interreg project funded within the transnational cooperation program between Italy and Switzerland 2007-2013. The aim of this project is the preservation and valorization of the cultural heritage linked to the walking historically paths crossing, connecting and serving the local territories. With the approach of leveraging the already existing tools, which generally consist of technical descriptions of the paths, the project uses the open source geospatial technologies to deploy innovative solutions which can fill some of the gaps in historical-cultural tourism offers. The Swiss part, and particularly the IST-SUPSI team, has been focusing its activities in the realization of two innovative solutions: a mobile application for the survey of historical paths and a storytelling system for immersive cultural exploration of the historical paths. The former, based on Android, allows to apply in a revised manner a consolidated and already successfully used methodology of survey focused on the conservation of the historical paths (Inventory of historical traffic routes in Switzerland). Up to now operators could rely only on hand work based on a combination of notes, pictures and GPS devices synthesized in manually drawn maps; this procedure is error prone and shows many problems both in data updating and extracting for elaborations. Thus it has been created an easy to use interface which allows to map, according to a newly developed spatially enabled data model, paths, morphological elements, and multimedia notes. When connected to the internet the application can send the data to a web service which, after applying linear referencing and further elaborating the data, makes them available using open standards. The storytelling system has been designed to provide users with cultural insights embedded in a multimedial and immersive geospatial portal.

    The phytohormone gibberellin (GA) regulates various developmental processes in plants such as germination, greening, elongation growth, and flowering time. DELLA proteins, which are degraded in response to GA, repress GA signaling by inhibitory interactions with PHYTOCHROME-INTERACTING FACTOR (PIF) family transcription factors. How GA signaling is controlled downstream from the DELLA and PIF regulators is, at present, unclear. Here, we characterize GNC (GATA, NITRATE-INDUCIBLE, CARBON-METABOLISM INVOLVED) and GNL/CGA1 (GNC-LIKE/CYTOKININ-RESPONSIVE GATA FACTOR1), two homologous GATA-type transcription factors from Arabidopsis thaliana that we initially identified as GA-regulated genes. Our genetic analyses of loss-of-function mutants and overexpression lines establish that GNC and GNL are functionally redundant regulators of germination, greening, elongation growth and flowering time. We further show by chromatin immunoprecipitation that both genes are potentially direct transcription targets of PIF transcription factors, and that their expression is up-regulated in pif mutant backgrounds. In line with a key role of GNC or GNL downstream from DELLA and PIF signaling, we find that their overexpression leads to gene expression changes that largely resemble those observed in a ga1 biosynthesis mutant or a pif quadruple mutant. These findings, together with the fact that gnc and gnl loss-of-function mutations suppress ga1 phenotypes, support the hypothesis that GNC and GNL are important repressors of GA signaling downstream from the DELLA and PIF regulators.

  19. Did Georges de la Tour use optical projections while painting Christ in the Carpenter"s Studio?

    Stork, David G.

    2005-03-01

    Recently it has been theorized that some painters as early as 1420 used concave mirrors (and, later, converging lenses) to project real inverted images onto their supports which they then traced and painted over. We consider a specific painting adduced as evidence for this bold theory, the Lorainnese Baroque master Georges de la Tour"s Christ in the carpenter"s studio (1645). We perform analyses of the reflections and shadows -- "cast" shadows and "form" shadows -- to infer the source(s) of illumination. We find compelling evidence that this source is the candle flame depicted within the painting and held by Christ. We find it implausible that the source is direct solar illumination, which has the intensity demanded by the projection theory, or artificial illumination as hypothesized by theory proponents. Similar analyses of several other paintings by de la Tour uniformly support the conclusion that the illumination is small and artificial within the space of the tableau (i.e., a candle), not extremely powerful illumination from outside the tableau. We created a very simple computer graphics model to test and illustrate part of our conclusions. Our research is the first application of technical shadow analysis to the question whether artists as early as the 15th century used optical projections when painting. Careful reading of the historical record of de la Tour"s working methods supports our technical results and extend the growing image analytic methods and historical sources rebutting the theory.

    At the operational level, the number of investigational new drugs or candidates for development per dollar spent in research, and the number of patents per year are highly integrated measures of productivity and, thus, difficult to influence at the individual or lab level. Hence, different metrics are needed to assess and thereby improve productivity in research at the individual and group level. This review centers on a case study, including over 70 interviews, in a research department of a global pharmaceutical company as well as over 40 interviews in contract research organizations (CROs) and 5 in small biotechnology firms. For each lab, its value adding process was plotted according to lean six sigma methods and appropriate metrics were defined. We suggest a strong focus on short feedback loops in research as an indicator for efficiency. Our results reveal two categories of activities: creativity-driven ones and process-driven ones, both discussed with respect to the methodology used. The fundamental differences in nature of these activities require different sets of metrics to assess them. On the basis of these metrics, different organizational forms can be derived to achieve a lean research structure: innovation studios and process factories, respectively.

    A pedoarchaeological study was carried out in the archaeological site "Piani della Corona", located on a wide terrace at 500 m a.s.l. along the southwestern coast of Calabria, in southern Italy. The archaeological excavations exhumed an extensive settlement related to old to medium Bronze Age phases and traces of late Neolithic human colonization. On the basis of archaeological finds the pedostratigraphic succession can be partly dated. It consists of soils with variable features and andic properties, which include yellowish-brown (in places more reddish), deep argillic (Bt) horizons with variable amounts of clay coatings in pores and dark brown infillings of soil material rich in organic matter, in places overlaid by thin, severely truncated, brown to dark brown, organic-mineral (A) horizons. These layers include late Neolithic ceramic artefacts (Diana style facies) and typical incineration burials found in biconical vases, that can be referred to 6500-5000 years BP. The prehistoric layers are widely overlaid and strongly superimposed by a paleosurface of the early to medium Bronze age. This surface is affected by many pole holes left by large rectangular, apsidal wooden huts (not preserved), ploughed furrows, excavated cisterns, ditches and trenches, often filled by organic-rich dark brown material. Also hearths with charcoal remains, burials, vases and other diagnostic ceramic fragments occur. The upper portion of the pedostratigraphic succession consists of thicker brown A horizons, that appear cyclically ploughed during historical times (archaeologically not well dated as a consequence of their reworking for agricultural practices), with abrupt irregular boundaries often entering the underlying horizons. Micromorphological observations confirmed the presence of clay coatings within pores of Bt horizons, showing that they represent relict features (i.e. related to inactive illuvial processes, at present), as often fragmented and with smooth-banded to grainy

    The Passo della Morte block-slide covers a relative large area in the Carnic Alps, along the left side of the Tagliamento River, between Forni di Sotto and Ampezzo (N-E of Italy). The high seismicity and the presence of the landslide increase the risk associated to the interest area. Moreover the large volume of material involved in the landslide (a few million of cubic meters), the presence of important infrastructure such as the road and two tunnels which cross the landslide, as well as the presence of the Tagliamento River that flow at the foot of the landslide, make the area very vulnerable. This study concerns with the western part of the Deep Seated Gravitational Slope Deformation (DSGSD). It focuses on the potential instability of a rock slope (crossed by road tunnels) and its connection with the DSGSD activity. The main objectives of this study are: monitoring the rock mass movement, studying the seismic site effect and defining the stratigraphic and geological characteristics of involved materials. Two vibration sensors have been installed inside the potential landslide: a short-period seismometer and a piezoelectric transducer. The microseismic activity recorded by the sensors has been analyzed, with particular regard to periods characterized by rapid changes in recorded seismic signals, and then correlated with the precipitation trend to evaluate the existence of a possible correlation between these phenomena. The microseismic activity study has highlighted the existence of a close link between microseisms and acoustic emissions recorded respectively by the seismometer and by the piezoelectric transducer. In addition, the comparison with the rainfall pattern has shown a direct relationship between different rainfall events and the sharp increase of microseismic activity detected by the two instruments. The correlation is good, even if acoustic emissions appear to be more sensitive than microseisms to short duration and low intensity rainfall events. The

    Eight centuries of the history of art and of Padua's scientific and technological culture deposited on the stones and frescoes of its Palace of Law ("Palazzo della Ragione") make this great work of urban architecture a part of the city's collective identity. This "palimpsest", legible only to a restricted circle of specialists, should be accessible to a vaster public interested in understanding this object symbol of local culture. The project planned for interactive exploration on the web is a series of digital models, employing tomographic-endoscopic visualizations and, in future, multi-resolution images. The various models devised allow the visitor to superimpose the Palace's current conditions on the various transformations undergone over the centuries. Similarly, comparisons can be made between the astrological fresco cycle with maps of the heavens, cosmological hypotheses, ancient and contemporary astrological treatises, and the related exchange of knowledge between the Orient and the Occident.

    The new occurrence of the bryozoan Zoobotryon verticillatum Della Chiaje, 1822 is herein recorded in multiple places throughout Azores archipelago. Where introduced, this species has caused important ecological and economical damage and therefore is regarded as invasive. In the Azores, no detrimental effects have yet been noted. The species is so far restricted to marinas (Horta, Faial Island; Vila Franca do Campo, São Miguel Island) and a natural coastal pool located near a secondary harbour (Lajes do Pico, Pico Island). A total of 29 colonies were counted during a specific survey conducted in August 2008 in the marina of Horta. The distribution of the species throughout the eastern and central island groups denotes a wide dispersion area and offers control or eradication measures a low probability of success together with the lack of harbour management practices that could effectively prevent the arrival, settlement and dispersal of non-native species transported by human-assisted means.

    Riassunto. Lo scopo di questo studio è quello di valutare i costi dei farmaci (con particolare riferimento alle terapie con farmaci biologici) utilizzati nella terapia di conversione in una popolazione non selezionata di pazienti affetti da carcinoma del colon-retto in stadio avanzato, al fine di ottenere una resezione epatica R0. In questa rassegna sono stati selezionati i report completi e gli aggiornamenti di tutti gli studi clinici randomizzati (di fase II e fase III) che confrontassero almeno 2 regimi di terapia con farmaci biologici in prima linea in pazienti affetti da carcinoma del colon-retto in stadio avanzato di malattia. I costi dei farmaci sono stati ricavati dalla nostra Farmacia Ospedaliera e sono espressi in euro (€). Il nostro studio inizia con la valutazione di 683 abstract. 48 tria sono stati considerati adeguati per una successiva analisi. Una valutazione più approfondita ha portato all'esclusione di 37 trial, lasciando alla valutazione finale 11 studi clinici randomizzati (3 trial di fase II, per un totale di 522 pazienti, e 8 studi di fase III, per un totale di 7191 pazienti). I costi dei farmaci utilizzati nella terapia di conversione aumentano con la sostituzione del 5-fluorouracile con la capecitabina e, in misura maggiore, con l'introduzione degli agenti biologici. In questo lavoro sono presentati due punti chiave. Primo, i costi degli agenti farmacologici utilizzati nei regimi di prima linea a base di agenti biologici più comunemente utilizzati nel trattamento del carcinoma del colon-retto in stadio avanzato sono molto variabili. Secondo, i dati di efficacia dei regimi pubblicati, in termini di tassi di resezione, dipendono dalla selezione dei pazienti, dalle caratteristiche del tumore e dal tipo di schema di terapia.

    Two important factors that influence customer satisfaction in large supermarkets or hypermarkets are adequate parking facilities and short waiting times at the checkout counters. This paper describes the simulation analysis of a large supermarket to determine the optimal levels of these two factors. SAS Simulation Studio is used to model a large supermarket in a shopping mall with car park facility. In order to make the simulation model more realistic, a number of complexities are introduced into the model. For example, arrival patterns of customers vary with the time of the day (morning, afternoon and evening) and with the day of the week (weekdays or weekends), the transport mode of arriving customers (by car or other means), the mode of payment (cash or credit card), customer shopping pattern (leisurely, normal, exact) or choice of checkout counters (normal or express). In this study, we focus on 2 important components of the simulation model, namely the parking area, the normal and express checkout counters. The parking area is modeled using a Resource Pool block where one resource unit represents one parking bay. A customer arriving by car seizes a unit of the resource from the Pool block (parks car) and only releases it when he exits the system. Cars arriving when the Resource Pool is empty (no more parking bays) leave without entering the system. The normal and express checkouts are represented by Server blocks with appropriate service time distributions. As a case study, a supermarket in a shopping mall with a limited number of parking bays in Bangsar was chosen for this research. Empirical data on arrival patterns, arrival modes, payment modes, shopping patterns, service times of the checkout counters were collected and analyzed to validate the model. Sensitivity analysis was also performed with different simulation scenarios to identify the parameters for the optimal number the parking spaces and checkout counters.

    In questo lavoro gli autori hanno valutato la possibilità di diagnosticare l’insufficienza venosa cronica cerebro-spinale (CCSVI) nei pazienti affetti da sindrome di Meniére resistente alle terapie mediche. Da aprile 2013 al luglio 2014 sono stati valutati 140 pazienti, 85 femmine, 55 maschi di età compresa tra 32 a 68 anni, con un’età media di 46 aa, affetti da sindrome di Meniere clinicamente definita secondo i criteri AAO 1995. I pazienti sono stati sottoposti ad un esame eco-colordoppler delle vene del collo e dei vasi venosi intracranici secondo il metodo di Zamboni. L’esame è stato eseguito anche in 100 pazienti sani, non affetti da malattia neurologica o audiovestibolare, di età simile a quella dei pazienti arruolati nello studio. L’incidenza della CCSVI, diagnosticata secondo il protocollo sviluppato dal Prof. Zamboni, nei pazienti con sindrome di Meniere è stata del 90%, con una presenza di lesioni più gravi sul lato interessato in casi unilaterali. Nella popolazione di controllo sono state rilevate anomalie compatibili con la CCSVI in soli tre pazienti (3%) comunque asintomatici. Vi è un’alta incidenza di CCSVI nei pazienti con malattia di Meniere clinicamente definita, in una percentuale tale da mettere in dubbio un evento casuale, soprattutto data la bassa prevalenza nel gruppo di controllo.

    La stipsi grave da rallentato transito è stata negli ultimi anni definitivamente riconosciuta come una condizione potenzialmente chirurgica, e nuove varianti tecniche sono state proposte in alternativa alla colectomia totale con ileo-retto anastomosi con l’obiettivo di minimizzare il rapporto rischi-benefici per il paziente. In quest’ottica la colectomia subtotale con anastomosi ceco-rettale (SCCRA) rappresenta nella nostra esperienza una valida alternativa, riducendo, a parità di efficacia, l’incontinenza e l’urgency postoperatoria, grazie alla preservazione della valvola ileo-cecale e del reservoir cecale. Tuttavia, a fronte di una buona percentuale di successi, legati soprattutto al miglioramento della selezione dei pazienti, la chirurgia della stipsi da rallentato transito presenta tuttora un non trascurabile numero di insuccessi e di complicanze tardive, spesso imprevedibili, e correlate alle varianti tecniche adottate. Nello specifico caso della SCCRA, la preservazione di un segmento colico verosimilmente malfunzionante (il ceco) è stata imputata come possibile causa di recidiva di stipsi cosiccome origine di complicanze chirurgiche tardive (distensione cecale, volvolo). L’obiettivo di questo studio è di analizzare in maniera critica le complicanze tardive di SCCRA, esaminando i rischi specifici della procedura per identificare possibili misure di prevenzione. A tal fine sono stati valutati i dati di 43 pazienti aderenti al follow-up sottoposti a SCCRA presso il nostro Istituto. Sono stati inclusi i pazienti sottoposti a re-intervento per complicanza tardiva chiaramente correlata a SCCRA presso il nostro centro. Sono state identificate 3 complicanze tardive (7%): una distensione cecale, un volvolo ileo-cecale, un volvolo ileale. Tutti i pazienti sono stati trattati chirurgicamente con successo. Solo nel primo caso è stata identificata una evidente condizione predisponente: la presenza di una defecazione ostruita non risolta associata ad un

    Anoectochilus roxburghii (Wall.) Lindl. (Orchidaceae) is an endangered medicinal plant in China, also called “King Medicine”. Due to lacking of sufficient nutrients in dust-like seeds, orchid species depend on mycorrhizal fungi for seed germination in the wild. As part of a conservation plan for the species, research on seed germination is necessary. However, the molecular mechanism of seed germination and underlying orchid-fungus interactions during symbiotic germination are poorly understood. In this study, Illumina HiSeq 4000 transcriptome sequencing was performed to generate a substantial sequence dataset of germinating A. roxburghii seed. A mean of 44,214,845 clean reads were obtained from each sample. 173,781 unigenes with a mean length of 653 nt were obtained. A total of 51,514 (29.64%) sequences were annotated, among these, 49 unigenes encoding proteins involved in GA-GID1-DELLA regulatory module, including 31 unigenes involved in GA metabolism pathway, 5 unigenes encoding GID1, 11 unigenes for DELLA and 2 unigenes for GID2. A total of 11,881 genes showed significant differential expression in the symbiotic germinating seed sample compared with the asymbiotic germinating seed sample, of which six were involved in the GA-GID1-DELLA regulatory module, and suggested that they might be induced or suppressed by fungi. These results will help us understand better the molecular mechanism of orchid seed germination and orchid-fungus symbiosis. PMID:26694378

    Low, but not freezing temperatures are a major factor limiting plant vegetative growth and development. It is not clear what signaling mechanism is used to limit plant growth in response to chronic low temperatures, thus it is important to continue to isolate and characterize genes whose activity/expression correlate well with cold responses. In this study, a novel GASA gene was isolated from Glycine soja and named GsGASA1. Quantitative real-time PCR analysis indicated that GsGASA1 expression responded to exogenous gibberellic acid (GA) and abscisic acid (ABA) treatments. Compared with wild-type plants under long-term cold treatment, the constitutive expression of GsGASA1 in transgenic Arabidopsis plants enhanced the inhibition of root elongation, while also increasing the transcript levels of RGL2 and RGL3, two of five DELLA genes in Arabidopsis. DELLA is a class of transcriptional regulators in GA signaling pathway restraining plant growth. Our results imply that GsGASA1 participates in chronic cold-induced root growth inhibition with the accumulation of DELLA genes. Lastly, a subcellular localization study using a yellow fluorescent protein (YFP) fusion protein indicated that GsGASA1 was localized to the plasma membrane, cytoplasm and nucleus.

    During the last restoration (2008-2011) of the polychrome terracotta altarpiece called Coronation of Virgin between Saints Rocco, Sebastian, Peter martyr and Antonio abbot, located in the collegiate church of S. Maria Assunta in Montecassiano (Macerata, Italy), scientific investigations were carried out to acquire detailed information about the painting technique. The identification of materials allowed a correct restoration. The altarpiece is almost entirely realized by Marco della Robbia (Fra Mattia), dates back to the first half of the XVI century and represents an interesting example of painted terracotta produced by using two different techniques: glazed polychrome terracotta and the "cold painting" technique. The characterization of the samples' material constituents was obtained by analysing the cross-sections and the fragments by different techniques (optical, SEM-EDS and ATR-FTIR microscopy as well as GC-MS), as the real nature of a component is often difficult to assess with one single technique. The optical microscope examination of paint cross-sections shows the presence of many layers, indicating the complexity of the paint stratigraphic morphologies. The original polychromy of della Robbia's masterpiece is constituted of cinnabar, red lake, red lead, orpiment, red ochre, lead white, lead tin yellow, green earth and raw umber. Two different types of gilding technique have been distinguished. The first one presents a glue mordant, and the second one shows an oil mordant composed by a mixture of red lead, red ochre, cinnabar and orpiment. The GC-MS analysis allowed the characterisation of linseed oil and a mixture of animal glue and egg as binding media stratigraphically located by the use of ATR-FTIR mapping microscopy. The analytical results of the painted terracotta integrated investigations show that original technique adopted is characterised by the application of pigments in an oil-binding medium directly applied on the substrates, probably treated

    The incorporation of virtual engineering into dentistry and the digitization of information are providing new perspectives and innovative alternatives for dental treatment modalities. The use of digital surface scanners with surgical planning software allows for the combination of the radiographic, prosthetic, surgical, and laboratory fields under a common virtual scenario, permitting complete digital treatment planning. In this article, the authors present a clinical case in which a guided implant surgery was performed based on a complete digital surgical plan combining the information from a cone beam computed tomography scan and the virtual simulation obtained from the 3Shape TRIOS intraoral surface scanner. The information was imported to and combined in the 3Shape Implant Studio software for guided implant surgery planning. A surgical guide was obtained by a 3D printer, and the surgical procedure was done using the Biohorizons Guided Surgery Kit and its protocol.

    Vegetation and climate during the Last Glacial Maximum (LGM) were considerably different than during the current interglacial (Holocene). In Europe large areas north of 40°N were entirely covered by continental ice-sheets and widespread permafrost, with temperatures around 10-20°C lower than at present, whereas further south aridity and temperatures 7-10°C cooler than today occurred. Cool climatic conditions and growing ice-sheets during the LGM radically reduced forest extent and diversity in Europe to a restricted number of so-called "refugia", mostly located in the southern part of the continent. The Euganian Hills in northeastern Italy are supposed to be one of the northernmost refugia of thermophilous mixed oak forest species (e.g. deciduous Quercus, Tilia, Ulmus, Fraxinus excelsior, Acer, Carpinus, Castanea) as well of some temperate mesophilous species (e.g. Fagus sylvatica, Abies alba) in Europe. In this study we present the first European chironomid-based quantitative temperature reconstruction for the LGM and address the question whether climate conditions were warm enough to permit the local survival of Quercetum mixtum species between ca. 31'000-17'000 cal yr BP. Chironomids preserved in a lake sediment core from Lago della Costa (7m a.s.l.), a lake on the border of the Euganean Hills in northeastern Italy, allowed quantitative reconstruction of Full and Late Glacial July air temperatures using a combined Swiss-Norwegian temperature inference model based on chironomid assemblages from 274 lakes. Our results suggest that July air temperatures never fell below 10°C which are considered necessary for forest growth. In general, mild climatic conditions prevailed between ca. 31'000-17'000 cal yr BP with temperatures ranging from ca. 11°C to 15.7°C. The expansion of thermophilous trees such as Quercus, Tilia, Ulmus, Fraxinus excelsior, Acer, Carpinus, Castanea (Quercetum mixtum) between ca. 30'000-23'000 cal yr BP can most likely be explained by climate

    Previously, it was shown that MAFIA (solutions of Maxwell's equations by the Finite Integration Algorithm), a three-dimensional simulation code, can be used to produce accurate cold-test characteristics including frequency-phase dispersion, interaction impedance, and attenuation for traveling-wave tube (TWT) slow-wave structures. In an effort to improve user-friendliness and simulation time, a model was developed to compute the cold-test parameters using the electromagnetic field simulation software package CST MICROWAVE STUDIO (MWS). Cold-test parameters were calculated for several slow-wave circuits including a ferruled coupled-cavity, a folded waveguide, and a novel finned-ladder circuit using both MWS and MAFIA. Comparisons indicate that MWS provides more accurate cold-test data with significantly reduced simulation times. Both MAFIA and MWS are based on the finite integration (FI) method; however, MWS has several advantages over MAFIA. First, it has a Windows based interface for PC operation, making it very user-friendly, whereas MAFIA is UNIX based. MWS uses a new Perfect Boundary Approximation (PBA), which increases the accuracy of the simulations by avoiding stair step approximations associated with MAFIA's representation of structures. Finally, MWS includes a Visual Basic for Applications (VBA) compatible macro language that enables the simulation process to be automated and allows for the optimization of user-defined goal functions, such as interaction impedance.

    2008-02-01

    Computer graphics models of tableaus in paintings provide a principled and controlled method for exploring alternate explanations of artists' praxis. We illustrate the power of computer graphics by testing the recent claim that Georges de la Tour secretly built an optical projector to execute Christ in the carpenter's studio, specifically that he traced projected images in two "exposures," with the illuminant in a different position in each. The theory's originator adduces as evidence his informal impressions that the shadows and highlights in the depicted image imply that the illuminant is in positions other than that of the depicted candle. We tested this projection claim by creating a computer graphics model of the tableau and adjusting the location of the model's illuminants so as to reproduce as closely as possible the pattern of shadows and highlights in the depicted scene. We found that for one "exposure" the model illuminant was quite close to the depicted candle, rather than in the position demanded by the projection theory. We found that for the other "exposure" no single illuminant location explained all highlights perfectly but the evidence was most consistent with the illuminant being in the location of the candle. Our simulation evidence therefore argues against the projection theory for this painting, a conclusion that comports with those from earlier studies of this and other paintings by de la Tour. We conclude with general lessons and suggestions on the use of computer graphics in the study of two-dimensional visual art.

    The direction of reading has been found to have a significant effect upon aesthetic preference, with left-to-right readers showing a preference for stimuli with a rightward directionality while right-to-left readers prefer stimuli with a leftward directionality. This study looks at a large set of posed, studio photographs to study the cultural interaction between direction of reading and lateral organisation, comparing a corpus of 735 nineteenth-century photographs from Iran (right-to-left reading) with a similar corpus of 898 photographs from Spain (left-to-right readers). Five separate types of composition were studied: linear ordering, usually by height; couples; individuals posing by a chair; individuals posing by a table; and portraits. Lateral preferences were found for all five types of photograph, with the lateral organisation of Iranian photographs being the reverse of that in the Spanish photographs. These data provide support for the influence of direction of reading upon aesthetic organisation in naturalistically produced photographs.

    Social parasites exhibit several characteristics that allow them to exploit their host species efficiently. The smaller size of parasite species is a trait commonly found in ants. In this work, we investigated several aspects of the reproductive biology of Acromyrmex ameliae De Souza, Soares & Della Lucia, a recently discovered parasite of Acromyrmex subterraneus subterraneus Forel. Sexuals of A. ameliae are substantially smaller than those from host species. Parasite queens laid significantly less worker eggs than host queens and inhibit sexual production of the host. The sex ratio of parasite species is highly female biased. Interestingly, we have observed parasite coupling on the laboratory, inside the nests and in the ground, opening the possibility to use controlled mating to study genetic approaches of parasitism in the ants.

    Non-contact measurements can be effectively used in civil engineering to assess the variation of structural performance with time. In the last decades this approach has received considerable interests from researchers working in the field of structural health monitoring (SHM). Indeed, non-contact measurements are very attractive because it is possible to perform non intrusive and non destructive investigations even being at a significant distance from the targets. Within this context, contactless measurements of the tie-rod vibrations in the Santa Maria della Consolazione Temple in Todi (Italy) are presented in this paper. In particular, laser vibrometer and radar interferometer measurements are used to estimate natural frequencies and mode shapes. This information is crucial to obtain the tensile axial force in the tie-rods, which can be used as an indicator of structural integrity or possible failure. Furthermore, a novel approach is proposed where drones (Unmanned Aerial Vehicles) can be successfully used to improve the effectiveness and the accuracy of the experimental activities.

    Integration and harmonization of large spatial data sets is not only since the introduction of the spatial data infrastructure INSPIRE a big issue. The process of extracting and combining spatial data from heterogeneous source formats, transforming that data to obtain the required quality for particular purposes and loading it into a data store, are common tasks. The procedure of Extraction, Transformation and Loading of data is called ETL process. Geographic Information Systems (GIS) can take over many of these tasks but often they are not suitable for processing large datasets. ETL tools can make the implementation and execution of ETL processes convenient and efficient. One reason for choosing ETL tools for data integration is that they ease maintenance because of a clear (graphical) presentation of the transformation steps. Developers and administrators are provided with tools for identification of errors, analyzing processing performance and managing the execution of ETL processes. Another benefit of ETL tools is that for most tasks no or only little scripting skills are required so that also researchers without programming background can easily work with it. Investigations on ETL tools for business approaches are available for a long time. However, little work has been published on the capabilities of those tools to handle spatial data. In this work, we review and compare the open source ETL tools GeoKettle and Talend Open Studio in terms of processing spatial data sets of different formats. For evaluation, ETL processes are performed with both software packages based on air quality data measured during the BÄRLIN2014 Campaign initiated by the Institute for Advanced Sustainability Studies (IASS). The aim of the BÄRLIN2014 Campaign is to better understand the sources and distribution of particulate matter in Berlin. The air quality data are available in heterogeneous formats because they were measured with different instruments. For further data analysis

    StormCenter Communications is involved in innovative technology development to enhance decision making between NOAA NWS, FEMA and the State of Texas Governor’s Division of Emergency Management (GDEM). The approach that we are using will enable us to leverage the production of LIVE and recorded programs that can focus on raising climate literacy in schools, in public and in the workforce. Through strong data and technology networks such as the ESIP Federation, we are able to collect, produce and deliver interesting and engaging content to a wide audience in order to clarify any climate misconceptions that may exist. No longer does distance have to be a barrier for connecting science with society. It is time to connect scientists with teachers and students, decision makers and the public. The EVTT is a 46-inch multi-touch plasma screen capable of displaying earth and space imagery along with GIS layers and real-time data in order to improve decision making. The visual displays have helped citizens better understand the Earth as a system. Combining the EVTT with StudioEarth(R) is expected to enable vast improvements in decision making and improved climate literacy. Schools can connect to StudioEarth® to introduce students to NASA and NOAA scientists who are directly involved in studying the climate and how it is changing. We are also part of the ESIP Federation network opening the doors to a large number of scientists who are studying our changing Earth. Stories can be produced to introduce the students to the scientist and their work and animations and model output can be used during LIVE question and answer sessions. For organizations connected to Internet2, StudioEarth® has an Internet2 connection to move large amounts of data and information as we have located our facilities on the campus of UMBC in Baltimore. Through innovative approaches to improved communications, StormCenter is focused on providing quality science content to enhance decision making

    In questo studio osservazionale retrospettivo abbiamo confrontato le complicanze post-operatorie tardive e precoci di pazienti affetti da malattia emorroidaria con prolasso circonferenziale (P4-E4 secondo la classificazione PATE 2000) sottoposti ad intervento chirurgico con tecnica Milligan-Morgan (variante laser a fibre ottiche) e con tecnica PPH-Stapler. Nello studio sono stati inclusi 160 pazienti sottoposti a trattamento chirurgico tra gli anni 2001 e 2007. Il gruppo A è composto da 80 pazienti (50 maschi; 30 femmine; età media di 39; range 23-57 anni) trattati con tecnica Milligan-Morgan (variante laser a fibre ottiche); il gruppo B composto da 80 pazienti (58 maschi; 22 femmine; età media di 40; range 23-60 anni) trattati con tecnica PPH-Stapler. Le complicanze precoci sono state eventi trombotici (6 casi in M-M vs 1 in PPH) e ritenzione urinaria (13 MM vs 5 PPH) senza casi di sepsi. Le complicanze tardive invece sono state: sanguinamento occasionale del 13.5 % nel gruppo M-M vs 10 % nel gruppo PPH; incontinenza alla defecazione 2.5 % (M-M-group) vs 5% (PPH-group) con p < 0.1; dolore persistente 2.5 % (MM) vs 5 % (PPH) con p < 0.1; soiling 18.75 % (MM) vs 0 % (PPH) con p < 0.001; eventi ricorrenti 5 % nel gruppo PPH vs 0 % in M-M (p < 0.05); residuo di malattia 7.5 % nel gruppo M-M vs 0 % in PPH con p < 0.01. In conclusione, dai nostri dati osservati, la tecnica PPHStapler risulta essere più indicata della tecnica Milligan- Morgan per il trattamento chirurgico del prolasso emorroidario nonostante possa essere seguita da gravi complicanze con una specifica indicazione però nella malattia emorroidaria con prolasso circonferenziale tipo P4- E4. Nella malattia emorroidaria con uno o più noduli invece, crediamo sia più indicato un trattamento chirurgico con tecnica Milligan-Morgan (variante laser a fibre ottiche).

    Verranno presentati i risultati preliminari di uno studio sistematico delle distribuzioni di energia spettrale (SED) di un campione statisticamente significativo di alcune centinaia di AGN (sia di tipo 1 che di tipo 2) selezionati dalla survey XMM-COSMOS. La vasta mole di dati disponibili sull'intero spettro elettromagnetico permette di calcolare le SED medie per diversi intervalli di redshift e luminosita'. Una stima affidabile della SED e' di fondamentale importanza per il calcolo della luminosita' bolometrica e quindi per lo studio della fisica dei processi di accrescimento su SMBH, per la loro evoluzione con il tempo cosmico.

  8. Characterization of the procera tomato mutant shows novel functions of the SlDELLA protein in the control of flower morphology, cell division and expansion, and the auxin-signaling pathway during fruit-set and development.

    procera (pro) is a tall tomato (Solanum lycopersicum) mutant carrying a point mutation in the GRAS region of the gene encoding SlDELLA, a repressor in the gibberellin (GA) signaling pathway. Consistent with the SlDELLA loss of function, pro plants display a GA-constitutive response phenotype, mimicking wild-type plants treated with GA₃. The ovaries from both nonemasculated and emasculated pro flowers had very strong parthenocarpic capacity, associated with enhanced growth of preanthesis ovaries due to more and larger cells. pro parthenocarpy is facultative because seeded fruits were obtained by manual pollination. Most pro pistils had exserted stigmas, thus preventing self-pollination, similar to wild-type pistils treated with GA₃ or auxins. However, Style2.1, a gene responsible for long styles in noncultivated tomato, may not control the enhanced style elongation of pro pistils, because its expression was not higher in pro styles and did not increase upon GA₃ application. Interestingly, a high percentage of pro flowers had meristic alterations, with one additional petal, sepal, stamen, and carpel at each of the four whorls, respectively, thus unveiling a role of SlDELLA in flower organ development. Microarray analysis showed significant changes in the transcriptome of preanthesis pro ovaries compared with the wild type, indicating that the molecular mechanism underlying the parthenocarpic capacity of pro is complex and that it is mainly associated with changes in the expression of genes involved in GA and auxin pathways. Interestingly, it was found that GA activity modulates the expression of cell division and expansion genes and an auxin signaling gene (tomato AUXIN RESPONSE FACTOR7) during fruit-set.

    Ethylene plays an important role in organ growth. In Arabidopsis, ethylene can inhibit root elongation by stabilizing DELLA proteins. In previous work, it was found that ethylene suppressed cell expansion in rose petals, and five unisequences of DELLA genes are induced by ethylene. However, the mechanism of transcriptional regulation of DELLA genes by ethylene is still not clear. The results showed that the expression of RhGAI1 was induced in both ethylene-treated and ETR gene-silenced rose petals, and the promoter activity of RhGAI1 was strongly induced by RhEIN3-3 in Arabidopsis protoplasts. What is more, RhEIN3-3 could bind to the promoter of RhGAI1 directly in an electrophoretic mobility shift assay (EMSA). Cell expansion was suppressed in RhGAI1-Δ17-overexpressed Arabidopsis petals and promoted in RhGAI1-silenced rose petals. Moreover, in RhGAI1-silenced petals, the expression of nine cell expansion-related genes was clearly changed, and RhGAI1 can bind to the promoter of RhCesA2 in an EMSA. These results suggested that RhGAI1 was regulated by ethylene at the transcriptional level, and RhGAI1 was a direct target of RhEIN3-3. Also, RhGAI1 was shown to be involved in cell expansion partially through regulating the expression of cell expansion-related genes. Furthermore, RhCesA2 was a direct target of RhGAI1. This work uncovers the transcriptional regulation of RhGAI1 by ethylene and provides a better understanding of how ethylene regulates petal expansion in roses.

  10. The Tomato (Solanum Lycopersicum cv. Micro-Tom) Natural Genetic Variation Rg1 and the DELLA Mutant Procera Control the Competence Necessary to Form Adventitious Roots and Shoots

    2012-01-01

    Despite the wide use of plant regeneration for biotechnological purposes, the signals that allow cells to become competent to assume different fates remain largely unknown. Here, it is demonstrated that the Regeneration1 (Rg1) allele, a natural genetic variation from the tomato wild relative Solanum peruvianum, increases the capacity to form both roots and shoots in vitro; and that the gibberellin constitutive mutant procera (pro) presented the opposite phenotype, reducing organogenesis on either root-inducing medium (RIM) or shoot-inducing medium (SIM). Mutants showing alterations in the formation of specific organs in vitro were the auxin low-sensitivity diageotropica (dgt), the lateral suppresser (ls), and the KNOX-overexpressing Mouse ears (Me). dgt failed to form roots on RIM, Me increased shoot formation on SIM, and the high capacity for in vitro shoot formation of ls contrasted with its recalcitrance to form axillary meristems. Interestingly, Rg1 rescued the in vitro organ formation capacity in proRg1 and dgtRg1 double mutants and the ex vitro low lateral shoot formation in pro and ls. Such epistatic interactions were also confirmed in gene expression and histological analyses conducted in the single and double mutants. Although Me phenocopied the high shoot formation of Rg1 on SIM, it failed to increase rooting on RIM and to rescue the non-branching phenotype of ls. Taken together, these results suggest REGENERATION1 and the DELLA mutant PROCERA as controlling a common competence to assume distinct cell fates, rather than the specific induction of adventitious roots or shoots, which is controlled by DIAGEOTROPICA and MOUSE EARS, respectively.

    The paper shows the results of a diagnostics survey, based on the ground penetrating radar (GPR), seismic tomography and microtremor horizontal-to-vertical ratio (HVSR) method, to understand the causes of some static instability problems affecting the Church of San Francesco della Scarpa in Lecce (Apulia region, Southern Italy). The prospecting falls within the more general framework of a diagnostic investigation campaign for the restoration of the monument. This study case points out the great effectiveness of the employed diagnostic methods, when used in an integrated way, for detecting cracks and inhomogeneities in the inner structure of masonry building elements [1-2]. With regard to GPR prospecting, in order to better evidence the micro-fracture, a new algorithm, based on a clutter removal technique, has been used. In particular, it removes various unwanted signals such as cross talk, initial ground reflection and antenna ringing. Moreover, seismic tomographies provided complementary information on the mediocre state of conservation of some load bearing structures of the church. Finally, HVSR method allowed to study the relationship between decay patterns, instability problems and seismic response of the monument.

    Executive Summary The objective of this study was to develop a “Virtual Design Studio (VDS)”: a software platform for integrated, coordinated and optimized design of green building systems with low energy consumption, high indoor environmental quality (IEQ), and high level of sustainability. This VDS is intended to assist collaborating architects, engineers and project management team members throughout from the early phases to the detailed building design stages. It can be used to plan design tasks and workflow, and evaluate the potential impacts of various green building strategies on the building performance by using the state of the art simulation tools as well as industrial/professional standards and guidelines for green building system design. Engaged in the development of VDS was a multi-disciplinary research team that included architects, engineers, and software developers. Based on the review and analysis of how existing professional practices in building systems design operate, particularly those used in the U.S., Germany and UK, a generic process for performance-based building design, construction and operation was proposed. It distinguishes the whole process into five distinct stages: Assess, Define, Design, Apply, and Monitoring (ADDAM). The current VDS is focused on the first three stages. The VDS considers building design as a multi-dimensional process, involving multiple design teams, design factors, and design stages. The intersection among these three dimensions defines a specific design task in terms of “who”, “what” and “when”. It also considers building design as a multi-objective process that aims to enhance the five aspects of performance for green building systems: site sustainability, materials and resource efficiency, water utilization efficiency, energy efficiency and impacts to the atmospheric environment, and IEQ. The current VDS development has been limited to energy efficiency and IEQ performance, with particular focus

    Santa Maria della Palomba's Sanctuary was built in XV century on a pre-existing medioeval crypt, in a splendid landscape situation, on the front looking south of the ravine on which stands Matera, integrating in a wonderful way underground and sub divo building; in fairly following time one important cycle of frescoes renewed decoration of underground church. In the long run, felt the building into decay, structures and frescoes were flooded and damaged; so that from 1980 were executed important restoration works, realizing ventilation canals under the floor of hypogeic church, in which were incorporated heating pipes, joined to solar thermic panels, wanting to determine the thermo-hygrometric optimum conditions for conservation. Almost thirty years after, willing restorate the frescoes, it was necessary to caracterize completely and objectively physical existing conditions. So was used an integrated mix of some non-invasive sensing techniques: - internal and external high resolution Sanctuary's measurement, using laser scanner 3D, in WebGIS ambient, so as to specify, in particular, whether dimensional data of non accessible parts (thickness of rock-bank, morphology and way of lying down of fracture lines), whether consistence state of frescoes; - thermo-hygrometrical sensing of surfaces, using infrared thermography, during a time of two weeks, in correspondence of many storm, so that to establish the relation between eventual atmospherical conditions variations and changes in conditions of surfaces; - continuous sensing of condition of surfaces, by means of thermo-hygrometrical and temperature sounds; - continuous sensing of operating temperature, by means of a globothermometer; all these tools were linked in a net with a data logger, and informations were transmitted using Web to computer in the office of the Society responsible for the procedure. Remote sensing integrated system proved high liability, allowing many important functions : - to georefer all data

    Negli ultimi cinquanta anni siamo stati testimoni di una straordinaria rivoluzione della conoscenza e comprensione della nostra stella grazie alla nascita dell'Eliosismologia, lo studio delle oscillazioni solari. Analogamente a ciò che accade nella Terra durante i terremoti, anche l'interno del Sole è pervaso continuamente da onde sismiche che provocano piccole oscillazioni, ovvero deformazioni della fotosfera. Le oscillazioni sono la manifestazione di diversi processi che avvengono all'interno della struttura del Sole e le frequenze sismiche dei modi osservati e misurati sulla superficie sono legate direttamente ai parametri fisici degli strati interni attraversati dalle onde sismiche. Lo studio delle oscillazioni rappresenta, quindi, l'unico metodo diretto per studiare la struttura e la dinamica interna del Sole. In questo articolo verranno illustrate le caratteristiche generali delle oscillazioni solari e verranno presentati i risultati importanti e i progressi notevoli raggiunti grazie all'Eliosismologia.

    With respect to food safety, many works have studied the effectiveness of self-monitoring plans of food companies, designed using the Hazard Analysis and Critical Control Point (HACCP) method. On the other hand, indepth research has not been made concerning the adherence of the plans to HACCP standards. During our research, we evaluated 116 self-monitoring plans adopted by food companies located in the territory of the Local Health Authority (LHA) of Foggia, Italy. The general errors (terminology, philosophy and redundancy) and the specific errors (transversal plan, critical limits, hazard specificity, and lack of procedures) were standardized. Concerning the general errors, terminological errors pertain to half the plans examined, 47% include superfluous elements and 60% have repetitive subjects. With regards to the specific errors, 77% of the plans examined contained specific errors. The evaluation has pointed out the lack of comprehension of the HACCP system by the food companies and has allowed the Servizio di Igiene degli Alimenti e della Nutrizione (Food and Nutrition Health Service), in its capacity as a control body, to intervene with the companies in order to improve designing HACCP plans.

    Introduzione. I dati statistici per il 2015 parlano di un peggioramento generale delle condizioni di vita e di salute della popolazione in Italia. Le possibili ricadute chiamano l’infermiere ad un coinvolgimento in tema di disuguaglianze nella salute. Lo studio è stato realizzato con lo scopo di valutare quanto gli infermieri conoscono e percepiscono la correlazione fra le condizioni di salute della popolazione e le iniquità di sistema. Metodo. E’ stato condotto uno studio esplorativo attraverso un aggiornamento bibliografico rispetto a precedenti lavori e la somministrazione di questionari a campioni di convenienza di professionisti e studenti di infermieristica e valutazione dei risultati secondo la prospettiva del mixed method. Risultati. La bibliografia infermieristica presente sul piano quantitativo è molto limitata. Il questionario fornisce risposte utili alla valutazione della percezione delle disuguaglianze nella salute in termini di equità orizzontale e verticale. Conclusioni. La conoscenza delle disuguaglianze nella salute non può essere al margine dei lavori scientifici e della stessa letteratura professionale. E’ necessario ridurre il divario fra gli aspetti valoriali propri della professione, che riverberano nella percezione delle iniquità esistenti, e l’assunzione piena del sapere correlato ai determinanti socio-economici della salute e della malattia.

    Sommario INTRODUZIONE: È stata valutata prospetticamente la variabilità interosservatore relativamente alla diagnosi di alterazioni focali della parete vescicale tra due operatori con diverso livello di esperienza. MATERIALI E METODI: Due operatori con diverso livello di esperienza in ecografia hanno esaminato indipendentemente nella stessa sessione 87 pazienti consecutivi (età media 68 anni; range 33–80; 75 maschi; 15 donne) sottoposti successivamente a cistoscopia entro 1–2 giorni. Prima dell’inizio dello studio la metodologia di studio è stata standardizzata. Il grado di accordo sulla presenza, sede, dimensioni e numero delle alterazioni parietali della vescica è stato calcolato con il metodo della Kw. RISULTATI: Il grado più elevato di accordo (k = 1) è stato raggiunto relativamente alla presenza delle alterazioni parietali, mentre un accordo sostanziale è stato ottenuto per le dimensioni (k = 0.78), numero (k = 0.72) e sede (k = 0.62). CONCLUSIONI: In questo studio la differenza di esperienza tra due operatori non è emersa nella diagnostica delle alterazioni parietali della vescica anche in ragione di una metodologia standardizzata di studio.

    Una delle principali e più temute complicanze della resezione anteriore di retto è stata ed è la deiscenza anastomotica. Solitamente, sia essa una scelta di principio od a discrezione del chirurgo operatore, viene confezionata una ileostomia laterale di sicurezza con lo scopo di prevenire tale circostanza. Scopo di tale studio è stato quello di investigare circa la utilità della stomia laterale di sicurezza quale strumento di prevenzione della deiscenza anastomotica, mettendo a paragone il decorso post-operatorio dei paziente con e senza stomia laterale. Le evidenze hanno portato alla conclusione che il confezionamento della stomia laterale di sicurezza è fattore di protezione non tanto dell’evento deiscenza anastomotica in senso stretto, quanto delle complicanze e della evoluzione clinica della stessa, vedasi ad esempio tasso di ricorrenza di deiscenza/quadro clinico in corso di deiscenza/ tempi di degenza, pur rendendosi necessario sottolineare l’assenza di significatività statistica nel tasso di mortalità nei due gruppi in studio. Cosi detto appare dunque sinottico affermare che il confezionamento di ileostomia laterale di sicurezza in corso di resezione anteriore di retto non determina una diretta azione sull’evento “deiscenza anastomotica” né “morte”, purtuttavia modifica certamente in positivo il decorso clinico ed evolutivo dell’evento “deiscenza anastomotica”.

Riassunto Introduzione Le mappe tematiche consentono una più rapida ed immediata lettura delle differenze geografiche nella distribuzione di dati riferiti ad un territorio specifico. Lo scopo dello studio è mostrare, per la prima volta, l’applicazione di alcuni strumenti statistici e cartografici, nell’analisi dell’uso dei farmaci nella popolazione pediatrica di una regione italiana e valutare le differenze intra-regionali. Metodi Per valutare il tipo di distribuzione geografica delle prescrizioni, sono stati calcolati i tassi di prevalenza standardizzati (punteggi-z) a livello di ASL, Distretti Sanitari e Comuni. Per valutare la correlazione con le ospedalizzazioni è stato usato il coefficiente di correlazione di Pearson; per valutare l’esistenza di autocorrelazione spaziale è stato usato l’indice I di Moran. Tramite l’uso della statistica G di Getis-Ord sono stati identificati cluster di aree ad alto e basso livello di prevalenza. Infine con un modello di regressione logistica è stata stimata la probabilità di ricevere almeno una prescrizione nel corso dell’anno per tutti i pazienti inclusi nello studio. Risultati Con l’uso delle mappe è possibile vedere che le prescrizioni non sono correlate con lo stato di salute della popolazione, ma sono correlate con l’attitudine prescrittiva del pediatra. Questo è confermato anche dal modello di regressione logistica costruito per stimare la probabilità di ricevere almeno una prescrizione considerando come variabili indipendenti l’età, il sesso, la prevalenza di ricoveri nel distretto di residenza, l’attitudine prescrittiva del pediatra, la classe di età del pediatra e la durata della convenzione del pediatra con l’Azienda Sanitaria Locale (ASL). Conclusioni Gli interventi primari per razionalizzare l’uso degli antibiotici in et

    Within the realm of evaluating self-monitoring plans, developed based on the Hazard Analysis and Critical Control Points (HACCP) method and adopted by food companies, little research has been done concerning the quality of the plans. The Servizio di Igiene degli Alimenti e della Nutrizione (Food and Nutrition Health Service) of the Local Health Authority of Foggia, Italy, has conducted research with the aim to adopt a system of indexes and indicators for the qualitative evaluation of HACCP plans. The critical areas considered were the following: simplicity, specificity, feasibility and adherence. During the period from January 2004 to June 2005, the evaluation grid was used in examining 250 HACCP self-monitoring plans of food companies. For the analysis of the determining factor four groups were considered, with reference to HACCP self-monitoring plans designed: group 1 - with the aid of a qualified team; group 2 - with the aid of an unqualified team; group 3 - with the aid of an unqualified expert; group 4 – without the aid of an expert. The mean values of the measures elaborated decrease towards insufficiency moving from group 1 to group 4. In particular, collaboration by teams of unqualified experts brought about drafting unacceptable HACCP plans on the levels of specificity and adherence, with respect to the HACCP method. The method proposed of the analysis of the indexes and indicators beginning with an evaluation sheet can also help the individual company to better adjust contribution by internal or external professionals to the company.

    RiassuntoLo scopo dello studio è quello di verificare l’incidenza del timore postoperatorio ai movimenti nei pazienti sottoposti ad artroplastica totale del ginocchio (TKA) e di determinare l’associazione di questo timore con i provvedimenti da adottare. Lo studio prospettico riguarda 78 pazienti sottoposti ad TKA primaria per osteoartrite. L’incidenza di timore al movimento è stata detenninata con l’uso della Tampa Scale of Kinesiophobia (TSK). I pazienti sono stati valutati in tre fasi temporali: 2 settimane. 4 settimane e 6 mesi dopo l’intervento chirurgico. In tutte e tre le fasi sono stati valutati il dolore e l’entità della flessione, mentre l’aspetto funzionale è stato preso in considerazione soltanto sei mesi dopo l’intervento, secondo la Oxford knee score 1. Il timore al movimento è stato registrato in 17 pazienti (21,8%). Quelli con maggiore entità di timore hanno dimostrato di conseguire risultati significativamente meno buoni in termini di dolore, grado di flessione e funzionalità rispetto a quelli con limitata paura. Miglioramento del dolore e della flessione sono stati progressivamente conseguiti nel tempo in entrambi i gruppi, ma i risultati migliori vengono raggiunti nel gruppo con minore paura al movimento. Lo studio ha dimostrato che la paura postoperatoria alla motilità si associa significativamente con il dolore, l’entità della flessione e la funzionalità del ginocchio. Altri Autori haImo rilevato che il timore preoperatorio alla motilità del ginocchio fa prevedere limitazioni funzionali postoperatorie. In conclusione il timore della motilità si rileva in una significativa proporzione dei pazienti dopo TKA e si associa con gonalgia, e minore flessione e funzionalità, e dunaue questa paura rappresenta un richio di scarsi risultati dopo artroplastica totale del ginocchio.

    La prevalenza mondiale del diabete nel 2000 è stata stimata essere del 2.8% con una previsione del 4.4% nel 2030. A causa della neuropatia e dei processi ischemici che ne derivano, i pazienti diabetici sono purtroppo predisposti all’insorgenza di infezioni a carico del piede con un rischio di amputazione molto elevato. A tal proposito, un trattamento rapido ed efficace del processo necrotizzante impedirebbe complicanze maggiori e la stessa amputazione. Il nostro studio consiste in un’analisi retrospettiva condotta su 20 pazienti atta a valutare l’efficacia del sostituto dermico autologo bioingegnerizzato (Hyalograft 3D Autograft) in associazione alla V.A.C (vacuum assisted closure) Therapy per il trattamento delle ulcere diabetiche, rispetto ai metodi sinora impiegati. I pazienti selezionati, a seconda del trattamento eseguito, sono stati suddivisi in due gruppi omogenei di dieci pazienti ciascuno. Il gruppo controllo è stato trattato con il metodo standard, ovvero con debridment chirurgico e innesti cutanei autologhi, mentre il gruppo studio è stato trattato con il metodo in analisi. La raccolta dei dati ha suggerito come l’impiego combinato del sostituto dermico bioingegnerizzato e della pressione negativa determini, rispetto al gruppo controllo, un aumento della percentuale di guarigione, una riduzione del tasso di recidiva di lesioni anche estese e una maggiore ripresa della deambulazione autonoma. In conclusione, la nostra analisi ha evidenziato un metodo sicuro, affidabile e competitivo per il trattamento di ampie lesioni necrotizzanti del piede diabetico. Anche se ulteriori valutazioni sono necessarie, crediamo fortemente che l’associazione del derma bioingegnerizzato e della pressione negativa possa condurre ad una rapida ed efficace guarigione delle ulcere, migliorando la qualità della vita del paziente diabetico.

    Background. Gli ambienti di apprendimento clinico sono definiti come una rete di fattori interagenti nel contesto, in grado di influenzare gli esiti dell’apprendimento degli studenti. La soddisfazione degli studenti è considerata un indicatore del raggiungimento degli esiti dell’apprendimento ed è determinante a partire dalla prima esperienza di tirocinio. Scopo. Analizzare l’esperienza di apprendimento clinico degli studenti infermieri del primo anno di corso dopo il primo tirocinio clinico ed identificare i principali determinanti della soddisfazione degli studenti. Metodo. Lo studio osservazionale è stato realizzato in cinque sedi universitarie italiane del Corso di Laurea in Infermieristica. 420 studenti hanno compilato la versione italiana della “Clinical Learning Environment, Supervision and plus Nurse Teacher (CLES+T) scale” al termine del primo tirocinio clinico. Risultati. I punteggi medi assegnati alle dimensioni della scala variano da 4.02 (clima di apprendimento) a 3.30 (relazione di tutorato). La maggior parte degli studenti è soddisfatto della propria esperienza di tirocinio (75.6%), ma sono emerse differenze in relazione alle diverse sedi di tirocinio clinico. Discussione. I principali determinanti della soddisfazione sono lo stile di leadership del coordinatore infermieristico e l’integrazione teoria-pratica nella relazione fra tutor clinico, universitario e studente. Conclusioni. I risultati dello studio contribuiscono alla comprensione della prima esperienza di tirocinio degli studenti. Tuttavia, sono necessarie ulteriori ricerche per determinare le variabili organizzative specifiche e i modelli tutoriali in grado di aumentare la soddisfazione degli studenti, per sviluppare strategie formative basate sull’integrazione tra tutor universitari e guide di tirocinio.

    Scopo. La valutazione della formazione accademica è diventata fondamentale nell'Unione Europea da quando il Processo di Bologna ha incoraggiato tutte le università europee a raggiungere elevati standard di qualità nella formazione. Anche se diversi studi sono stati condotti sulla qualità della formazione negli studenti di infermieristica, pochi hanno esplorato questa tematica dalla prospettiva degli studenti. Lo scopo di questo studio è stato di descrivere l'esperienza della qualità formativa negli studenti del corso di laurea in infermieristica. Metodo. E’ stato utilizzato il metodo fenomenologico per studiare 55 studenti (età media 24 anni; 73% donne) che frequentavano il corso di laurea in infermieristica in tre università del centro Italia. Risultati. Dall'analisi fenomenologica sono emersi i seguenti cinque temi: 1) Qualità dei docenti: capacità di insegnamento, preparazione, sensibilità per gli studenti, autodisciplina; 2) Integrazione teoria-pratica e comunicazione tra l'insegnamento e l'area clinica; 3) gestione generale e organizzazione del corso; 4) la qualità delle infrastrutture: biblioteche, aule, tecnologie dell'informazione, servizi, amministrazione, comunicazione; e 5) tutorato clinico: umanità, relazioni e capacità del tutor clinico di guidare e supportare lo studente. Conclusione. I risultati di questo studio forniscono una comprensione nuova e più approfondita sul significato della qualità della formazione negli studenti di infermieristica. Gli studenti ritenevano che la qualità della formazione consistesse nella sensibilità dei docenti verso i loro problemi e nell’umanità, capacità interpersonali, guida e supporto dei tutor cli.

    Da una presa visione del messaggio mediatico, riguardo alla figura infermieristica, il ruolo e l’evoluzione che la professione ha avuto negli anni, restano sconosciuti ai non addetti ai lavori. L’obiettivo della ricerca è definire come l’immagine dell’infermiere è descritta dai media. Metodo: analisi di articoli di due quotidiani (a tiratura locale e nazionale) in merito a numero di articoli riguardante la professione, posizione dell’articolo, argomento (malasanità, truffe/reati, lavoro/tagli, riconoscimenti/elogi). A questo è seguita un’integrazione con analisi di quotidiani on line, utilizzando parole chiave. Analisi dei medical drama televisivi, relativamente a presenza, competenze, relazione con medico e paziente, aspetti sociali, contesto di cura in cui opera, impatto sul benessere della persona ed eventuali aspetti etico-deontologici. Risultati: su circa trecento articoli relativi all’ambito della salute, trentanove parlano di infermieri; cinque di questi hanno rilevanza da prima pagina. Il 39% degli articoli parla di truffe/reati, il 19% lavoro/tagli, il 15% malasanità. Dai quotidiani on line emerge un 66% di articoli relativi a truffe/reati. Nei format televisivi alla figura si porge poca attenzione, con competenze generiche a qualsiasi figura diversa da quella medica; quasi esclusivamente di sesso femminile, rispecchia stereotipi considerati di genere. Discussione: da entrambi i media presi in esame emerge una figura poco professionale; nello specifico della televisione, la figura dell’infermiere non ha una precisa identità ed è relegata a un ruolo di debolezza, riscontrabile nel contesto lavorativo e privato.

    L’eventualità di un’emorragia intraoperatoria è la complicanza più temuta nel corso di una surrenectomia laparoscopica. Tale rischio diventa ancora più importante nel caso in cui siano presenti anomalie anatomiche rappresentate da duplicità della Vena Cava Inferiore (VCI) e da anomali confluenze delle vene surrenali. Tale riscontro, osservato nel caso descritto, ha fornito lo spunto per uno studio sull’incidenza di dette anomalie e sulle metodiche utili a prevenire la complicanza emorragica. Una donna di 39 anni è giunta alla nostra osservazione a causa di una neoformazione non funzionante del surrene destro andata incontro ad un lento ma progressivo accrescimento volumetrico. Tale neoformazione era stata riconosciuta a distanza di tempo nel corso di controlli clinici e strumentali praticati per una Poliposi Familiare del Colon, sottoposta in altra sede a Proctocolectomia Restorativa circa 8 anni prima. Già in quell’epoca era stata documentata una duplicità congenita della VCI associata ad altre anomalie vascolari e viscerali. Nel corso della surrenectomia laparoscopica, dopo aver clippato e sezionato la vena surrenalica alla sua confluenza cavale, è stata riconosciuta una seconda vena con sbocco nella vena renale destra; anch’essa trattata in modo analogo e con esito favorevole. La presenza di una duplice VCI, pur essendo un reperto piuttosto raro, è divenuta di più frequente riscontro con la diffusione di tecniche di diagnostica per immagini sempre più elaborate, in particolare l’AngioTC. La presenza di tali anomalie può rendere problematiche alcune manovre di radiologia interventistica quali il posizionamento di un filtro cavale o il cateterismo selettivo di una vena surrenalica. È però in ambito chirurgico che la duplicità della VCI può causare i maggiori inconvenienti, rappresentati da un possibile danno vascolare. La maggior parte degli Autori ritiene in proposito indispensabile un valido studio per immagini preoperatorio quale

    Sommario INTRODUZIONE: Scopo del presente lavoro è effettuare un’analisi preliminare retrospettiva di una nuova tecnica ad immagini, la TC ad ultrasuoni, utilizzata per determinare l’estensione della massa neoplastica mammaria, prima di decidere un’eventuale asportazione chirurgica. MATERIALI E METODI: Nel periodo compreso tra agosto 2007 e giugno 2008, 41 donne con diagnosi di tumore mammario hanno avuto una stadiazione della neoplasia usando la TC ad ultrasuoni. In seguito le pazienti sono state sottoposte a risonanza magnetica con mezzo di contrasto del seno per evidenziare ulteriori aree di estensione tumorale, la presenza di linfoadenopatie del cavo ascellare, di multifocalità e di bilateralità, che avrebbero potuto compromettere l’intervento chirurgico. Entrambe le tecniche sono state poi comparate per confrontarne l’accuratezza. RISULTATI: L’accuratezza della nuova tecnica, la TC ad ultrasuoni è stata del 68%, mentre quella della risonanza magnetica del 54%. L’incremento dell’accuratezza della diagnosi che ne è derivato è stato del 14% (2–28%). La TC ad ultrasuoni non appare, pertanto, inferiore alla risonanza magnetica. CONCLUSIONI: È necessario un ulteriore studio per meglio valutare la capacità e le prospettive di questa nuova tecnica nella fase pre-operatoria.

    Il sinus pilonidali (SP) è una patologia comune che colpisce in genere la popolazione giovane e localizzandosi nella regione intergflutea. Per la sua cura sono state utilizzate tecniche conservative e descritte diverse tecniche chirurgiche, queste ultime consistenti in chiusura primaria dell’escissione chirurgica, la marsupializzazione e le chiusura con flap della breccia chirurgica. Il presente studio si propone di valutare l’efficacia di un metodo chirurgico. La casistica si riferisce a 151 pazienti sottoposti a trattamento chirurgico tra Gennaio 2007 e Settembre 2014, che vengono suddivisi per età, sesso, durata dell’intervento e della degenza postoperatoria, oltre alle complicanze (deiscenze ed infezioni della ferita), recidive e domensioni pel pezzo operatorio. L’età media dei pazienti affetti da sinus pilonidalis si aggira tra i 14 ed i 66 anni (media 25,18). In 105 pazienti (69,5% del totale) si è proceduto a chiusura primaria della ferita, ed il 46 (30,5% del totale) si è adottata la tecnica tension-free. Non si sono osservate differenze statistiche tra i gruppi rispetto all’età, al sesso, alla durata dell’intervento ed a quella della degenza postoperatoria. Solo 9 pazienti operati con chiusura primaria (8,6%) e 3 pazienti (6,5%) operati con tecnica tension-free hanno presentato una recidiva postoperatoria. In 17 pazienti (7,9%) si è osservata la deiscenza della ferita, di cui 15 (14,3%) tra quelli trattati con chiusura primitive e 2 (4,3%) in quelli trattati con tecnica tension- free. Il 16 pazienti (10.6%) è stata osservata la formazione postoperatoria di sieroma o di infezione. In conclusione la tecnica tension free si dimostra metodo altrettanto efficace della chiusura primitiva.

    Il nostro studio ha lo scopo di confrontare gli eventi clinici ed i dati laboratoristici postoperatori di pazienti anziani coronaropatici con disfunzione ventricolare sinistra, sottoposti a rivascolarizzazione miocardica chirurgica eseguita con o senza ausilio della circolazione extracorporea. Studi recenti hanno evidenziato i vantaggi dell’intervento a cuore battente nei pazienti anziani, riportando una riduzione della morbidità postoperatoria e della disfunzione di organo. Tuttavia questi studi non analizzano l’impatto della disfunzione ventricolare sinistra sugli eventi postoperatori precoci e tardivi nei pazienti ad alto rischio. Abbiamo esaminato retrospettivamente 90 pazienti di età superiore ai 75 anni, con frazione di eiezione preoperatoria < 50%, sottoposti a bypass aortocoronarico, senza altre procedure cardiochirurgiche associate, tra Gennaio 2000 e Luglio 2009 presso il nostro Centro. I pazienti sono stati divisi in 2 gruppi: pazienti operati senza ausilio della circolazione extracorporea (a cuore battente) e pazienti operati con l’ausilio della circolazione extracorporea (a cuore fermo). Abbiamo confrontato I livelli sierici postoperatori degli enzimi CK, CK-MB e troponina T, indici di danno miocardico, e gli eventi cerebrovascolari. La mortalità intraospedaliera totale era del 2% (2 pazienti su 90) e simile in entrambi i gruppi (p=0.8336). I livelli medi di troponina T a 6, 24, 48 ore dopo l’intervento erano significativamente più bassi nei pazienti operati a cuore battente (p=0.0001; p=0.0021; p=0.0070). Non c’era una differenza statisticamente significativa nei 2 gruppi in termini di sopravvivenza (p=0.0764) e di eventi cerebrovascolari (p=0.3016) nell’immediato postoperatorio ed a 10 anni. I nostri risultati dunque mostrano che il non utilizzo della circolazione extracorporea nei pazienti ad alto rischio determinerebbe una più bassa incidenza di danno miocardico; tuttavia ciò sembra non influenzare a lungo termine la sopravvivenza

    The Venus transit on the Solar disc was for the first time observed in 1639, using "modern" instruments, by Gassendi. Yet since the following transit, an effect was perceived which modified Venus and Sun profiles at the moments of the first and second visual contact between the two celestial bodies. This effect was called "gutta nigra", i.e. black drop. Horn d'Arturo was widely interested in studies on the vision and on its effects on astronomical observations. In the following paper, he suggested what probably was the first correct explanation of the black drop effect. As stated on the Dictionary of Scientific Biography (ad vocem), Horn "clarified the effect on vision, especially in the astigmatic eye, of the suture of the eye lens and the formation of the so-called black drop".

    This paper focuses on the motives and long-term effects of the momentous decision to build a world-class biomedical research laboratory, the International Center for Chemical Microbiology, at the Istituto Superiore di Sanità in Rome, rather than develop domestic production of penicillin to meet the needs of a destitute postwar Italy. An institutionalist approach will provide a richer vision of the intersections of scientific and national political history in postwar Italy and the Cold War. The Center failed in its modernising mission due to an insular mentality producing an 'enclosure effect' against the State, the healthcare system and the pharmaceutical industry. The absence of a scientific base together with an economic policy of 'liberal protectionism' that placed premiums on import tariffs and the licensing of foreign products explains the path dependency of the pharmaceutical industry during the postwar years and its demise in the 1960s.

    L’obiettivo del nostro studio è la valutazione della strategia chirurgica più idonea nei casi di LABC (Locally Advanced Breast Cancer) in condizioni di ulcerazione e sanguinamento. La diagnosi clinica del LABC prevede nella maggior parte dei casi una massa mammaria estesa associata ad edema, eritema, retrazione e sanguinamento, dolore, superficie cutanea irregolare e coinvolgimento linfonodale. L’intervento chirurgico di scelta per le forme T3-T4 è la mastectomia radicale che rappresenta un trattamento adeguato per il controllo locale della patologia. In caso di forme localmente avanzate e ulcerate, pur essendo forme inoperabili, l’exeresi chirurgica si rende necessaria per una bonifica locale. La presenza di fenomeni di ulcerazione e sanguinamento non rende possibile avviare un trattamento chemioterapico neoadiuvante ed è necessario eseguire interventi chirurgici palliativi. Il trattamento chirurgico stesso richiede mutilazioni ampie ed associate procedure di chirurgia plastica. Spesso per l’estensione della malattia ed il sovvertimento del corpus mammae durante l’exeresi chirurgica della mammella, la sezione su zone esenti da neoplasia non consente la chiusura immediata dei lembi. Abbiamo considerato, su un campione di 288 pazienti affette da carcinoma mammario, 11 donne con forme avanzate fra T4a e T4c (3.8%). E’ stata posta indicazione a trattamento chirurgico perché pazienti provenienti dal Pronto Soccorso con anemizzazione per neoplasie avanzate ulcerate e sanguinanti, non candidabili in prima istanza a chemioterapia neoadiuvante citoriduttiva. Le procedure adoperate per la ricostruzione della mammella sono state in 2 pazienti la rotazione di un lembo muscolo cutaneo, in 4 casi un innesto cutaneo prelevato dalla coscia, in 4 casi è stata utilizzata una matrice dermica biologica - sostituto cutaneo (INTEGRA) che è stata poi sostituita con un successivo innesto cutaneo a distanza di circa 20-30 giorni. Sono state osservate recidive in 2 casi

    . La TEP alla 18 FDG, grazie all’uso della metodica qualitativa e quantitativa nell’analisi della lesione, è stata molto utile nello svelarne la natura. Veniva pertanto eseguita una surrenalectomia sinistra per via laparoscopica. L’esame istologico per entrambe le lesioni era in favore di feocromocitoma, Pass score 0. Nella fase post-operatoria la paziente veniva trattata con idrocortisone a dosi decrescenti fino ad un dosaggio giornaliero di 30 mg in associazione a 50 mg di fludrocortisone. Questo caso clinico dimostra ancora una volta la possibilità di falsi negativi da parte di tecniche di imaging funzionale specifiche. In questa esperienza, la TEP alla 18 FDG è stata molto utile. La RMN ha senza dubbio mostrato un valore incontestabile. In questa paziente non è stata trovata nessuna mutazione germinale a carico dei geni RET, VHL, SDHx.

    Scopo. L’obiettivo primario dello studio è implementare e utilizzare uno strumento validato per misurare il fenomeno delle dimissioni difficili, che possa supportare il personale infer- mieristico nella programmazione della dimissione del paziente ricoverato nei reparti di Geria- tria e Medicina. Gli obiettivi secondari sono: - Sperimentare l’utilizzo dell’indice di BRASS - Studiare le caratteristiche della popolazione a rischio di dimissione difficile Metodo. studio osservazionale prospettico per misurare il fenomeno delle dimissioni difficili attraverso l’implementazione dell’indice di BRASS nei reparti di Geriatria e Medicina dell’Ospedale di Rovigo Ulss 18, al fine di studiare le caratteristiche della popolazione a rischio di dimissione difficile. Risultati. In un campione di 165 pazienti il 42,4% (70) era rispettivamente a rischio alto e medio di dimissione difficile, mentre il 15,2% (25) era a basso rischio. La media dei punteggi BRASS era di 18,76. Il 37,6% dei pazienti ad alto rischio erano ricoverati in Geriatria, mentre in Medicina i pazienti si concentrano maggiormente nella classe medio rischio. Conclusioni. Lo studio ha permesso di misurare il fenomeno delle dimissioni difficili classi- ficando i pazienti nei gruppi di rischio. L’analisi delle dimissioni protette ha fatto emergere la congruenza tra punteggio BRASS e caratteristiche del campione. Lo strumento non richiede tempi di compilazione lunghi, è di supporto al processo decisionale dell’infermiere perché rileva la necessità di creare un percorso strutturato sulla dimissione del paziente, in modo sistematico e programmato, evitando la dispersione di informazioni importanti al fin di garantire la continuità assistenziale.

    Il trattamento dell’iperparatiroidismo primario è quasi esclusivamente chirurgico e consiste nell’esplorazione sistematica delle quattro ghiandole con asportazione di quella( e) patologica(e). Le più moderne tecniche di diagnosi (ecotomografia, scintigrafia 99 mTc sestamibi), migliorando le possibilità di individuare la ghiandola responsabile della malattia, consentono l’esecuzione di tecniche miniinvasive quando vi è concordanza tra i risultati delle due tecniche, ma la sensibilità di tali indagini è inficiata dalle ectopie ghiandolari, da paratiroidi intratiroidee, da malattia multighiandolare o dalla contemporanea presenza di malattie tiroidee. Il presente studio illustra una nuova tecnica di imaging scintigrafico intraoperatorio ed indaga sulla sua possibilità di migliorare la localizzazione intraoperatoria della paratiroide patologica. A tal fine, 5 pazienti sono state sottoposte a tale metodica, tutte trattate con paratiroidectomia previa esplorazione completa delle quattro ghiandole con tecnica tradizionale, con monitoraggio intraoperatorio del paratormone. Alla tecnica convenzionale è stato aggiunto l’impiego della gamma camera intraoperatoria. Abbiamo valutato la concordanza dei risultati di tale esame con i dati dell’esplorazione chirurgica e con il dosaggio intraoperatorio del paratormone. In tutte e 5 le pazienti si è osservata una perfetta concordanza tra la localizzazione della ghiandola patologica con la scintigrafia intraoperatoria e l’esplorazione chirurgica, ed il dosaggio intraoperatorio del paratormone ha confermato i dati. Anche il follow-up ad un mese ha confermato l’eradicazione della malattia. La gamma camera intraoperatoria sembra quindi poter migliorare le possibilità di localizzazione della ghiandola responsabile dell’iperparati-roidismo primario, favorendo l’impiego di tecniche mini-invasive e migliorando i risultati dinanzi a casi “difficili”.

    Nonostante i significativi vantaggi della chirurgia laparoscopica rispetto a quella laparotomica, essa era considerata controindicata per le donne gestanti. Attualmente si confrontano opinioni contrastanti riguardo alla sicurezza durante la gestazione della chirurgia laparoscopica, specie se nell’ultimo trimestre. Lo scopo di questo studio è quello di valutare la fattibilità della chirurgia laparoscopica in donne gestanti in caso di addome acuto analizzando retrospettivamente la casistica della pazienti ricoverate tra il gennaio 1995 ed il gennaio 2013 presso l’Emergency Department della Cerrahpasa Medical Faculty. Sono stati pertanto analizzati tutti i dati clinici riguardanti le gestanti sottoposte a chirurgia laparoscopica, comprese le cartelle cliniche, gli interventi eseguiti, i reperti anatomopatologici, e le informazioni riguardanti il parto. Nella casistica sono rientrate 14 donne gravide (in media alla 19,2° settimana di gestazione, distribuite tra 9 e 33 settimane), di cui 11 sottoposte ad appendicectomia laparoscopica, 2 a colecistectomia laparoscopica ed 1 per scopi diagnostici. In media il parto si è espletato alla 37,4° settimana di gestazione (tra la 35° e la 40° settimana). Due pazienti hanno avuto un parto prematuro, ma in nessune dei casi si sono verificate complicazioni durante le manovre laparoscopiche, e cioè danni all’utero, morti fetali o mortalità materna. Si conclude che la chirurgia laparoscopica può essere effettuata nel corso di tutti i trimestri della gravidanza, con il possibile vantaggio di una utile diagnosi differenziale in caso di dolori addominali acuti durante la gravidanza, e diminuzioni delle morti fetali dovute a ritardi diagnostici, e che tempi chirurgici più brevi riducono gli effetti negativi sulla madre e sul feto.

    L’identificazione della reale sede del tutmore è essenziale per la formulazione di un adatto algoritmo nei cancri localizzati distalmente nel colon-retto (CTC). In questo studio è stata indagata l’efficacia della localizzazione di tumori distali del colon-retto di quattro metodologia: la colonscopia, la TAC, l’imaging della RMN, e la PET con fluoro-18-desossi-glicosio tomografia computerizzata (CT), analizzando retrospettivamente le cartelle cliniche di 156 pazienti affetti, Fluorodeoxyglucose -positron emission tomography scan da tumore del colon-sigma, della giunzione retto sigmoidea e del retto sottoposti a trattamento chirurgico. Per quanto riguarda l’accuratezza delle quattro metodologie essa è risultata simile: 74% per la clolonscopia, 67% per la TAC, 75% per la RMN e 74% con la PET. La colonscopia è risultata meno sensibile nei tumori retto-sigmoidei (33%) mentre la TAC è risultata meno sensibile (26%) e la RMN meno specifica (33%) per i tumori del retto. In conclusione, confermando l’importanza di poter localizzare correttamente i tumori distali del colon retto al fine di determinare le strategia più accurate del trattamento, le indagini preoperatorie non forniscono dati di adeguata accuratezza per i tumori colon rettali distali, e solo l’uso combinato di esse può accrescere il risultato cercato.

    I tumori metastatici in genere hanno una cattiva prognosi, con sopravvivenza breve e raramente sono candidabili al trattamento chirurgico. Nel caso dei carcinomi differenziati della tiroide, la prognosi è solitamente migliore, grazie alla possibilità di un approcio multidisciplinare e soprattutto al trattamento radiometabolico dei secodarismi, dopo l’asportazione del tumore primitivo. Il caso presentato riguarda una donna di 65 anni, che è giunta alla nostra osservazione per una tumefazione mandibolare, risultata successivamente una metastasi da carcinoma follicolare della tiroide, a partenza da un voluminoso gozzo cervico-mediastinico normofunzionante, con ulteriori secondarismi a livello polmonare. Dopo un accurato studio pre-operatorio la Paziente è stata sottoposta a resezione della mandibola sinistra con ricostruzione mediante una protesi metallica e a tiroidectomia totale. Successivamente è stata trattata con quattro cicli di terapia radiometabolica con buona risposta. La Paziente è viva, senza ulteriore progressione di malattia a un follow-up di quarantasei mesi. Anche nei casi di tumori differnziati della tiroide in fase metastatica, l’opzione chirurgica va presa in considerazione per consentire alle terapie complementari di migliorare la prognosi in termini di sopravvivenza.

    L’innesto osseo è essenziale nella terapia chirurgica della labiopalatoschisi (LPS), ma i tempi di osteogenesi ed integrazione ossea nella sede ricevente possono procrastinare i successivi interventi di ortodonzia. Nel nostro studio è stata valutata la capacità della PRP (platelet-rich plasma) associata al trapianto osseo nel diminuire il tempo d’attesa e la durata del trattamento ortodontico in una coorte di 8 bambini, confrontandola con 8 controlli sottoposti a semplice innesto osseo. I risultati hanno mostrato come i soggetti sottoposti a trapianto osseo + PRP abbiano avuto la possibilità di essere sottoposti ad un trattamento ortodontico più precoce (155 giorni vs 298) e più breve (295 giorni vs 356) rispetto al gruppo di controllo. Inoltre nel gruppo di controllo si sono verificate con maggiore frequenza complicanze post-chirurgiche (quali fistole oro-nasali, disturbi periodontali, malattie dentali, perdita di spessore, massa o trabecolatura ossea) rispetto al gruppo sottoposto a PRP. Perciò l’associazione della PRP (platelet-rich plasma) al trapianto osseo è una metodica che sembra associarsi ad una diminuzione statisticamente significativa dei tempi di integrazione ossea nei pazienti affetti da LPS, con conseguente anticipazione della ortodonzia e miglioramento degli outcome chirurgici.

    Il riscontro di un incidentaloma surrenalico comporta un approfondimento diagnostico rivolto da un lato a chiarire la natura della lesione e nello stesso tempo ad accertare la presenza di una attività endocrina subclinica. Quest’ultima molto spesso è caratterizzata da una sindrome metabolica nella quale sono presenti Ipertensione arteriosa, Diabete Mellito di tipo 2 ed Obesità. Tali manifestazioni cliniche, indotte da una alterata secrezione cortisolica, configurano quindi una Sindrome di Cushing subclinica (SCS) nella quale, con il passare del tempo può verificarsi una compromissione della funzione cardiaca nonché un aggravamento del DM e dell’obesità. L’attuale orientamento di fronte ad una SCS, pur oggetto di dibattito, è a favore della surrenectomia laparoscopica (SL), anche in rapporto ai favorevoli risultati della terapia chirurgica nei confronti del trattamento medico. Gli Autori alla luce dell’esperienza personale su 26 casi di SL effettuati in un periodo di 6 anni, riportano i loro risultati in merito alla casistica generale e in particolare nei casi in cui era riconoscibile una SCS. Scopo del lavoro: verificare nel tempo se la SL ha comportato una normalizzazione dell’alterata secrezione cortisolica e un miglioramento della sindrome metabolica associata. Nell’arco temporale gennaio 2009-gennaio 2015 presso il Reparto di Chirurgia Generale A del Policlinico Universitario di Monserrato sono state effettuate 26 SL in 5 maschi e 21 femmine di età media di 53 anni. Le indicazioni alla SL comprendevano 11 incidentalomi, 7 sindromi di Cushing, 5 lesioni sospette per metastasi e 3 sindromi di Conn. Le SL sono state portate a termine in 22 casi (percentuale di conversione 15%), la durata media dell’intervento è stata di 162 minuti (range 65- 225) Nessuna mortalità e complicanze pari all’11%.

    Lo stress ossidativo gioca un ruolo importante nella patogenesi delle malattie neoplastiche. La prolidasi è un costituente della matrice metalloproteinasica, gioca un ruolo maggiore nel metabolismo del collagene, nell’accrescimento cellulare e nel rimodellamento strutturale. Una elevata attività prolidasica è stata dimostrata in molti casi di carcinomi. Lo scopo del presente studio è quello di indagare sull’attività sierica della prolidasi, dello stato ossidativo (TOS) ed antiossidativo (TAS) totale, e di valutare il loro rapporto con lo stadio del tumore, delle metastasi linfonodali e della massa neoplastica in pazienti con carcinoma mammario. Per lo studio sono state arruolate 35 pazienti con carcinoma della mammella e 40 soggetti di controllo. Sono stati rilevati i livelli di TAS, TOS e dell’attività prolidasica, calcolando gli indici di stress ossidativo (OSI). Come risultato i livelli di TOS, di OSI e dell’attività prolidasica sono risultati significativamente più elevati nelle pazienti con carcinoma mammario rispetto al gruppo di controllo (rispettivamente (P < 0.001, P < 0.001, P = 0.002). I livelli di TAS sono risultati significativamente inferiori nelle pazienti con carcinoma mammario rispetto al gruppo di controllo (P = 0,016). Sono stati rilevate correlazioni positive tra attività prolidasica, ed i livelli di TOS e di OSI con lo stadio tumorale, le metastasi linfoniodali e le dimensioni del tumore. Negativa è risultata la correlazione tra i livelli di TAS e le dimensioni del tunore, ma nessuna correlazione tra i livelli di TAS e lo stadio del tumore, come pure con l’infiltrazione linfonodale. Si conclude che l’elevata attività prolidasica del siero e lo stress ossidativo possono associarsi col carcinoma mammario. L’accresciuta attività prolidasica può essere messa in relazione con lo stadio e la prognosi del carcinoma mammario.

    Lo studio è finalizzato al rilevamento degli effetti del lauromacroglo, un agente sclerosante, sul tessuto tiroideo del coniglio, utilizzando 12 conigli divisi in due gruppi di sei ciascuno. Nel gruppo di studio è stato iniettato nel tessuto tiorideo 0,1 ml di lauromacrogolo, ed in quello di controllo lo stesso volume di soluzione fisiologica. Al controllo postoperatorio sono stati valutati il tasso di FT3, FT4, TSH, la presenza di aderenze e le differenze istopatologiche dei tessuti tiroidei. Non sono risultate differenza significative nel livelli di FT3, FT4, TSH (p>0,05) ma i livelli di , la presenza di aderenze e le differenze istopatologiche dei tessuti tiroidei. Ai controlli i valori di FT3, FT4 ed TSH non sono risultati significativamente differenti (p>0,05), mentre i livelli di FT3 sono stati significativamente differenti all’interno dei due gruppi (p=0,20). Non sono state riscontrate differenze macroscopicamente significative delle aderenze postoperatorie (p>0,05), ma flogosi e fibrosi sono risultate istologicamente più elevate nel gruppo di studio (p=0,003). Due sono i risultati importanti dello studio: la differenza non signifcativa dei test di funzione tiroidea tra i due gruppi, suggerendo che il lauromacrogol può essere usato con sicurezza senza rischi di ipo- o ipertiroidismo; la valutazione istopatologica su modello Erlich-Hunt ha dimostrato che flogosi e fibrosi sono significativamente accresciute nel gruppo di studio, indicando che il lauromacrogol più essere usato efficacemente e con sicurezza per il trattamento dei noduli tiroidei per provocare fibrosi, senza significative aderenze peritiroidee e differenze della funzione.

    Sommario INTRODUZIONE: L'artrite Idiopatica giovanile (AIG) determina alterazioni a carico della testa condilare dell'articolazione temporomandibolare (ATM). Nell'esordio oligo-articolare (OA) l'interessamento dell'ATM viene spesso trascurato perchè può essere asintomatico. Lo scopo di questo studio è quello di valutare la presenza di versamento intrarticolare (V) dell'ATM, mediante esame ecografico (US), nelle fasi precoci di malattia. MATERIALE E METODI: Sono stati studiati 68 bambini (57 bambine e 11 bambini, di età compresa tra 9,1 e 16, anni, età media: 11,02 ± 4,2 mesi) con AIG ad esordio OA. I pazienti (pz) erano sintomatici quando uno dei quattro sintomi seguenti era presente: 1) dolore ricorrente (a riposo o durante il movimento di apertura della bocca); 2) presenza di scrosci articolari; 3) presenza di limitazione nell'apertura della bocca; 4) locking intermittente. US è stato eseguito su entrambe le ATM sia in fase statica che dinamica, mediante ecografo General Electric (LOGIQ7) con sonda lineare (8,5 MHz) posizionata lungo l'asse maggiore del ramo condilare. Il V era presente quando lo spessore della capsula articolare era ≥1,5 mm. RISULTATI: 46/68 (68%) hanno presentato V a carico delle ATM; in 16 (35%) il V era bilaterale. 2/46 con V erano sintomatici, mentre in 44 non erano presenti sintomi. CONCLUSIONI: Questi dati suggeriscono che un'alta percentuale di bambini e giovani adulti con AIG ad esordio OA, nella fase iniziale della malattia, presenta un interessamento flogistico delle ATM anche in assenza di sintomi. L'US, non invasivo e facilmente ripetibile, ci offre importanti informazioni sul coinvolgimento articolare delle ATM ed è risultato utile nella diagnosi all'esordio.

Le caratteristiche cliniche e di laboratorio possono non essere utili per distinguere tra recidiva di AR e sovrapposizione di SA. Il ruolo della risonanza magnetica (RM) è stata descritto in diversi studi. Il nostro obiettivo è quello di valutare il ruolo della ecografia (US). Materiali e Metodi. Negli ultimi 4 anni sono stati eseguiti 31 esami di risonanza magnetica della mano e del polso nel sospetto di SA come complicanza di AR. È stata utilizzata una risonanza magnetica da 1.5 T (Siemens Symphony, Erlangen, Germania) con protocollo standardizzato, che comprendeva la somministrazione di mezzo di contrasto; è stata eseguita anche un'ecografia con power Doppler utilizzando un ecografo Philips IU22. RISULTATI: Sono stati analizzati undici punti (secondo lo studio di Graif) per ogni esame di RM e di US. Alla RM il versamento articolare (37,5% di recidiva AR vs 100% sovrapposizioni di SA) e l'edema dei tessuti molli (25% vs 100%) erano indicativi di SA. Anche ecograficamente il versamento articolare (31.3% di AR recidiva 73,3% vs sovrapposizione di SA) e l'edema dei tessuti molli (12,5% vs 60%) erano indicativi di SA. CONCLUSIONE: I nostri risultati confermano che il versamento articolare e l'edema dei tessuti molli sono suggestivi per sovrapposizione di SA e che la RM è più sensibile nella loro valutazione. Anche se l'US è meno sensibile della RM, essa è importante nel guidare procedure invasive e nella valutazione dei pazienti che non possono essere sottoposti a RM.

    RIASSUNTO. Scopo. Lo scopo di questo studio è stato quello di investigare l'influenza della probabilità di suicidio, con le sue caratteristiche sociodemografiche, e di procurare i dati per la prevenzione del suicidio tra le guardie di sicurezza privata che lavorano in condizioni di stress, essendo a contatto ininterrottamente con eventi negativi e traumatici di vita durante il loro lavoro. Metodi. Hanno partecipato allo studio 200 guardie di sicurezza privata e 200 persone dell'Università di Ankara. Per raccogliere i dati sono stati utilizzati un questionario riguardante le condizioni sociodemografiche dei partecipanti, la Suicide Probability Scale (SPS) e la Brief Symptom Inventory (BSI). Risultati. Genere, stato civile, stipendio, credenze religiose, vivere una situazione di pericolo di vita, passato di tentativi di suicidio, fumare e non avere una malattia cronica hanno causato statisticamente una differenza significativa sui punteggi di SPS tra il gruppo di guardie di sicurezza privata e quello di controllo. In aggiunta, c'è stata una correlazione positiva statisticamente significativa tra i punteggi totali delle sottoscale di SPS e quelli di BSI. Conclusioni. Allo stesso modo degli agenti di polizia e dei gendarmi, le guardie di sicurezza privata sono ad alto rischio di commettere e tentare il suicidio trovandosi in condizioni stressanti di lavoro e anche soffrendo del trauma secondario. È necessario che essi siano consapevoli della propria tendenza al suicidio e avere controlli psichiatrici regolari.

    Dopo il ripristino della circolazione sanguigna e dell’ossigenazione possono verificarsi gravi danni locali e sistemici ai tessuti temporaneamente ischemici, noti come danni da riperfusione. Lo scopo di questo studio è stato quello di indagare sui possibili effetti protettivi della melatonina nei confronti dei danni sistemici da riperfuzione nel tessuto epatico a seguito dell’occlusione dell’aorta sottorenale. Per questo studio sono stati impiegati un totale di 21 ratti Wistar-albini di sesso maschile, suddivisi in tre gruppi: I gruppo – laparotomia e contemporanea dissezione dell’aorta infrarenale; II gruppo – somministrazione intraperitoneale di circa 1 ml di fisiologica al 0,9% di NaCl 30’ prima e dopo l’operazione di occlusione. Dopo la laparotomia e sua dissezione, l’aorta sottorenale è clampata per 30’ e quindi riabitata al circolo di riperfusione per 2 ore; III gruppo – 30’ prima del clampaggio dell’aorta sottorenale è stata somministrata la malatonina, seguita dal clampaggio aortico per 30’ e un periodo di riperfusione di 2 ore. Sono stati quindi dosati i tassi sierici di aspartate aminotransferasi, alanine aminotransferasi, and lattato dehydrogenase, risultati significativamente più elevate nei gruppi II e III rispetto al gruppo I di controllo. Gli esami di laboratorio sono tornati ai livelli normali nel III gruppo dopo il trattamento. Sebbene si sia avuto un decremento del tasso sierico di IL-1β, IL-6, IL-18, TNF-α, e IFN- γ nel gruppo trattato con melatonina, questo decremento ha assunto valore statisticamente significativo per i livelli sierici di IL- 18, TNF-α, e IFN- γ in paragone con quanto osservato nel II gruppo. I tassi sierici dello stato totale di antiossidanti tissutali (TOC) e dell’indice di stress ossidativo dei tessuti (OSI) sono risultati diminuiti e quelli della capacità antiossidante (TAC) risultano accresciuti dalla melatonina. Il risultato di questo studio suggerisce effetti antiossidanti della

    Gli amartomi cistici retrorettali (Tailgut cysts) sono rare lesioni dello spazio presacrale che avendo rischio intrinseco di trasformazione maligna e recidiva sono normalmente trattate mediante asportazione chirurgica anche nel caso in cui siano asintomatiche. Negli ultimi vent’anni si sta affermando il trattamento mediante accesso addominale laparoscopico per la sua migliore esposizione delle strutture della pelvi e la sua minore invasività. In questo caso clinico presentiamo il trattamento del più grande amartoma cistico retrorettale asportato laparoscopicamente fino ad ora riportato in letteratura. Essendo nella maggior parte dei casi asintomatici, la diagnosi degli amartomi cistici retrorettali è spesso incidentale durante una visita medica di routine. Nel successivo studio è particolarmente indicata la RM per orientare la scelta dell’approccio chirurgico data la sua maggiore risoluzione nei tessuti molli e nella determinazione dell’invasività locale. La trasformazione maligna di queste lesioni si stima possa avvenire nel 14,1% dei casi, per questo l’exeresi chirurgica è la terapia di scelta. Tra i differenti approcci la tecnica transaddominale laparoscopica, se eseguita da chirurghi esperti nella chirurgia pelvica laparoscopica, garantisce la migliore visualizzazione degli organi pelvici e una minore morbidità. A causa del rischio di rottura e insemenzamento l’approccio laparoscopico non dovrebbe essere utilizzato in caso di sospetta malignità della lesione cistica. Il nostro caso corrobora la validità del trattamento laparoscopico degli amartomi cistici retrorettali, anche quando possiedono dimensioni considerevoli. Lo studio preo-peratorio è quindi cruciale per determinare la possibile malignità della lesione ed eseguire in tal caso un approccio laparotomico.

    La colite ulcerosa (UC) è una delle maggiori forme di colonpatia infiammatoria cronica recidivante. La capacità di identificare tipo, gravità e sensibilità alla terapia su parametri di laboratorio è da tempo oggetto di ricerca degli studi clinici. Lo scopo di questo studio è quello di accertare la relazione tra la viscosità del plasma (PV), l’attività della malattia e la risposta al trattamento medico. Lo studio si è svolto su 105 pazienti con UC e 42 volontari sani. I prelievi di sangue sono stati utilizzati per valutare la viscosità del plasma (PV), la velocità di eritrosedimentazione (ESR), la proteina C-reattiva ultrasensibile (hs-CRP), il D-dimero e il fibrinogeno. I pazienti con UC sono stati raggruppati in relazione al grado di attività flogistica (cioè 59 attivi e 46 in remissione). La PV è risultata più elevata in quelli con UC attiva rispetto a quella dei soggetti in remissione o nei soggetti sani. È risultata significativamente più elevata sia nei casi di UC refrattaria al trattamento steroideo rispetto a quelli sensibili (p< 0.001), e nelle UC rafrattarie alla ciclosrporina rispetto a quelli sensibili (p= 0.003). Con l’aumento della PV nei pazienti affetti da UC sono risultati significativamente associati il punteggio del SCCAI (Increased Simple Clinical Colitis Activity Index), dell’EGS (Endoscopic Grading Scale) e del HAD (Histological Disease Activity (HAD). Si conclude che la PV è un marker utile per la previsione di sensibilità al trattamento sterorideo e con ciclosporina nei pazienti con UC attiva. Potrebbe essere rimpiazzata dalla ESR e dalla hs-CRP come misura della risposta in fase acuta in quanto sufficientemente sensibile. Questi risultati possono essere utili per l’identificazione dei pazienti con UC attiva da destinare alla colectomia.

    RIASSUNTO. Scopo. Nella riabilitazione psichiatrica il piano di trattamento individuale può essere formulato a partire da strumenti che offrano una valutazione multidimensionale del paziente. Il lavoro si propone di analizzare il rapporto tra gravosità (distress degli operatori) e stile di recupero (integration e sealing over) dalla patologia psicotica. Ipotizzando che esso influenzi il carico gestionale, lo studio si pone l'ulteriore obiettivo di acquisire maggiori elementi che indirizzino la formulazione di piani terapeutico-riabilitativi più efficaci. Metodi. Lo studio è stato condotto presso un centro diurno psichiatrico, struttura semi-residenziale dei servizi psichiatrici del Sistema Sanitario Nazionale in Italia. 45 pazienti reclutati sono stati valutati mediante la Neuropsychiatric Inventory (NPI - versione italiana) e la Integration/Sealing Over Scale (ISOS - versione italiana), nell'arco di tre mesi (marzo-giugno 2014). Risultati. Nel campione esaminato è emerso che la disinibizione, l'irritabilità e l'apatia sono i sintomi che provocano maggiore distress negli operatori, in senso assoluto. Inoltre, i risultati indicano che depressione e ansia recano un grado maggiore di distress nei pazienti sealer. Discussione e conclusione. Gli aspetti della disinibizione, dell'irritabilità e dell'apatia sono risultati più gravosi per gli operatori in quanto richiedono maggiore coinvolgimento nella relazione terapeutica. Sintomi ansiosi e depressivi risultano più gravosi nel gruppo dei sealer, segnalando minore tenuta della negazione della psicosi. I dati osservati sembrano provare che conoscere, differenziare e approfondire i diversi aspetti dello stile di recupero di ciascun paziente consente di stimare l'impegno gestionale fin dalla presa in carico e di ridurre il distress e il rischio di burnout degli operatori.

    A versatile resource program was developed for diffusion tensor image (DTI) computation and fiber tracking. The software can read data formats from a variety of MR scanners. Tensor calculation is performed by solving an over-determined linear equation system using least square fitting. Various types of map data, such as tensor elements, eigenvalues, eigenvectors, diffusion anisotropy, diffusion constants, and color-coded orientations can be calculated. The results are visualized interactively in orthogonal views and in three-dimensional mode. Three-dimensional tract reconstruction is based on the Fiber Assignment by Continuous Tracking (FACT) algorithm and a brute-force reconstruction approach. To improve the time and memory efficiency, a rapid algorithm to perform the FACT is adopted. An index matrix for the fiber data is introduced to facilitate various types of fiber bundles selection based on approaches employing multiple regions of interest (ROIs). The program is developed using C++ and OpenGL on a Windows platform.

    In this pilot study, aimed at exploring the feasibility of a large-scale trial of low-dose aspirin in polycythaemia vera (PV), 112 PV patients (42 females, 70 males. aged 17-80 years) were selected for not having a clear indication for, or contraindication to, aspirin treatment and randomized to receive oral aspirin (40 mg/d) or placebo. Follow-up duration was 16 +/- 6 months. Measurements of thromboxane A2 production during whole blood clotting demonstrated complete inhibition of platelet cyclooxygenase activity in patients receiving aspirin. Aspirin administration was not associated with any bleeding complication. Within the limitations of the small sample size, this study indicates that a biochemically effective regimen of antiplatelet therapy is well tolerated in patients with polycythaemia vera and that a large-scale placebo-controlled trial is feasible.

  14. Imagination in harmony with science: Spectral analysis as a practical pedagogic tool in the voice studio

    NASA Astrophysics Data System (ADS)

    Rundus, Katharin Elaine

    Traditionally, voice teachers have relied on intuition and imagination to impart technical information to their students. Spectral analysis, generated on a personal computer, is now available, affordable and accessible to the twenty-first century voice teacher. These programs provide several acoustical functions using frequency, intensity and time to provide technical information about the human singing voice. This paper advocates the use of this technology as a supplemental and supporting strategy in addition to the traditional pedagogic modes of metaphor and intuition. To begin, the paper examines the acoustical principles that reflect beautiful singing and are necessary to an understanding of spectral analysis. Several figures are used that graphically explain the source-filter theory of vowels and how it is affected by the constant manipulation of a closed-open tube like the human vocal tract. Nine functions of Real Analysis (a spectral analysis program in real time manufactured by Tiger DRS, Inc.) are then examined and explained in relation to the singing voice. The paper goes on to outline a systematic vocal pedagogy in eight parts that can be used in harmony with spectral analysis, portrayed in an octagonal spiral figure. In the fourth chapter, this systematic vocal pedagogy is then integrated with spectral analysis to suggest a holistic and artistic method to use this technology. In a table format, several singing behaviors are identified, both negative and positive; training solutions using Real Analysis functions are outlined for each behavior. The paper concludes by pointing out that this technology is valuable because it teaches teachers about their own voice in a scientific manner and allows them to share this quantifiable information with their students. Furthermore, twenty-first century students are accepting of and eager for new technologies as they learn about their voices. This new technology does not change the traditional goals of voice training, but can be an essential tool for voice teachers as they work with their students to create beautiful singing.

    Il caso clinico che vi presentiamo riguarda la straordinaria localizzazione intra-addominale di un sinovial-sarcoma. Questo tumore dei tessuti molli generalmente interessa le piccole e grandi articolazioni. Sono state descritte altre localizzazioni a livello intra-addominale e retroperitoneale. La nostra paziente si ricovera per una tumefazione dolente dell’addome, alla TC addome si evidenzia una voluminosa massa intra-addominale che comprime e disloca i parenchimi e visceri circostanti e che affiora ai tessuti più superficiali della parete addominale. La biopsia eco-guidata della lesione, insieme allo studio immunoistochimico, permette di porre la diagnosi di sinovial-sarcoma. La paziente viene candidata ad un trattamento chemioterapico a scopo neoadiuvante. Per il sopraggiungere di anemizzazione da sanguinamento della neoplasia, valutata anche la risposta parziale al trattamento sistemico, si pone indicazione all’intervento chirurgico. La massa con peduncolo vascolare maggiore costituito dai vasi gastroepiploici di destra, viene completamente asportata. L’esame definitivo conferma la diagnosi di Sinovial-Sarcoma bifasico. L’indagine genetica condotta sul campione conservato in formalina non ha permesso, a causa della difficoltà di estrarre ed amplificare un quantitativo adeguato di RNA, di identificare la traslocazione (X; 18) (p 11.2; q 11.2) specifica del Sinovial-Sarcoma. La paziente è stata dimessa dopo un decorso clinico regolare. Il follow-up ad un anno non ha mostrato ripresa di malattia ma dopo 18 mesi alla TC torace-addome di rivalutazione si evidenzia la ripresa di malattia a livello intra-addominale e la presenza di metastasi polmonari bilaterali.

    Scopo: la dignità della persona assistita e il rispetto per quest’ultima sono aspetti imprescindibili della professione infermieristica. Sviluppare un sapere esperto è possibile qualora il professionista sanitario interpreti il proprio ruolo come soggetto coinvolto in maniera empatica. Lo scopo di questo studio è capire cosa influenzi la dignità degli assistiti attraverso i loro vissuti al fine di comprendere come offrire assistenza umanizzante. Metodo: l’indagine è stata condotta nell’ospedale di Valcamonica, su un campione di 20 soggetti, qui ricoverati nell’agosto 2015, corrispondenti a predefiniti criteri d’inclusione. Come strumento è stata utilizzata un’intervista semistrutturata attraverso domande funzionali al quesito di ricerca. Risultati: la dignità è considerata una caratteristica intrinseca in ogni essere umano. La maggior parte degli intervistati percepisce la dignità come mantenuta, durante il ricovero ospedaliero. I fattori che possono influenzarla sono riassumibili in tre categorie: fattori legati al comportamento del personale sanitario, all’ambiente ospedaliero ed alle condizioni dell’assistito. Conclusioni: la dignità è un concetto ad oggi astratto e nebuloso; ciò nonostante è qualcosa di cui ogni essere umano ha consapevolezza e sa quanto sia importante salvaguardarla. L’ambiente ospedaliero di per sé alienante e le condizioni di fragilità e dipendenza che spesso accompagnano la malattia possono ledere la dignità. Un comportamento corretto e disponibile da parte di chi assiste è ciò che più aiuta a mantenerla; l’approccio clinico che tiene conto solo della malattia e non dell’individualità della persona è inadeguato per ogni tipologia di assistito.

    INTRODUZIONE. In Italia negli ultimi anni l’aumento della sopravvivenza della popolazione ha comportato il cambiamento dello stato di salute, che vede l’incremento nella prevalenza delle patologie croniche (Osservatorio, 2011). L’ospedale, riservato alla fase acuta delle patologie, si integra necessariamente con le cure primarie. La continuità assume particolare rilevanza per la cura, assistenza e riabilitazione della persona assistita, così come l’appropriato utilizzo delle diverse tipologie di offerta socio sanitaria assistenziale e riabilitativa. OBIETTIVO. Al San Gerardo di Monza, nell’ambito della riabilitazione del paziente post-acuto, si analizza la fase che intercorre tra la dimissione prevista dall’ospedale e la data di accettazione presso gli istituti di riabilitazione. E’ possibile quantificare i tempi di attesa? L’ allocazione delle persone assistite è appropriata? Scopo dello studio osservazionale descrittivo è accertare la distribuzione dei giorni di attesa. Inoltre si ipotizza il ricorso all’Assistenza Domiciliare Integrata e a soluzioni innovative. Obiettivi sono la diminuzione delle giornate di degenza inappropriate e l’utilizzo delle risorse in modo congruo. RISULTATI. Delle 1083 persone in attesa di riabilitazione il 55% (652), a cui sono associate 4505 giornate “inappropriate”, è stato dimesso dall’ospedale oltre i tempi previsti. CONCLUSIONI. L’utilizzo dell’assistenza domiciliare, vantaggiosa per l’ospedale, può essere utilizzata solo per una minoranza di pazienti e in modo diseconomico. Per abbattere la totalità delle giornate, una soluzione innovativa può essere l’istituzione di posti letto a basso costo. E dato che la maggioranza dei casi sono solo ad alta complessità assistenziale ma a bassa intensità clinica potrebbero essere letti gestiti da infermieri.

    OBIETTIVI: descrivere, nella ASL 21 di Legnago (VR), l'andamento di alcuni indicatori sanitari tra il 2009, anno precedente all'avvio di un progetto triennale per la gestione integrata dell'assistenza al paziente con diabete mellito di tipo 2, e il 2012, ultimo anno del progetto. DISEGNO: studio longitudinale trasversale ripetuto. SETTING E PARTECIPANTI: tutti i pazienti diabetici di tipo 2 della ASL 21, identificati nei database aziendali (in base a esenzioni per patologia, accessi al servizio diabetologico, consumo di farmaci antidiabetici e strisce per la determinazione della glicemia) e nelle cartelle cliniche dei medici di famiglia. PRINCIPALI MISURE DI OUTCOME: numero di test diagnostici e di follow-up erogati, consumo di farmaci, prestazioni specialistiche, accessi al pronto soccorso, ricoveri e mortalità. RISULTATI: nonostante un calo generalizzato (-3,1%) nei test erogati dalla ASL 21 ai suoi assistititi nel periodo 2009-2012, l'analisi ha documentato un marcato aumento per gli esami previsti nella gestione del diabete, quali curve da carico glicemico (+104,3%), emoglobina glicata (+19,0%) e microalbuminuria (+296,1%). I soggetti identificati come diabetici sono aumentati da 8.084 nel 2009 (5,2%) a 9.221 nel 2012 (5,9%). Sono stati osservati aumenti nella prevalenza di pazienti visitati presso un servizio diabetologico (dal 22,6% al 39,0%), nonché negli utilizzatori di metformina (dal 28,0% al 37,5%), insuline (dal 13,5% al 18,3%) e incretine (dall'1,4% al 9,0%). Il consumo di sulfaniluree è, invece, calato (dal 49,9% al 40,8%), come anche l'erogazione di alcune prestazioni specialistiche, gli accessi al pronto soccorso e i ricoveri, mentre il tasso di mortalità è rimasto stabile (29,6 decessi x1.000/anno). CONCLUSIONE: durante il periodo di implementazione del progetto sembra essersi verificato un aumento della sensibilità diagnostica e una maggiore presa in carico del paziente diabetico. Anche se la natura osservazionale dello studio non consente

    Observing Solar eclipses at the totality path limits allows to measure solar diameter variations and lunar ephemerides corrections with an accuracy of a few hundredths of arcsecond. After a review of secular variations of solar diameter, presenting the eclipses of Rome 1567, London 1715, and New York City 1925, we present the current research on this topic and the phenomena occurring on the edges of the totality path. For the forthcoming eclipses, the location of observers must be chosen after calculations of limits and simulations of bead appearances and timings. We present our example in Valoria La Buena (Spain) for the 3 October, 2005 eclipse. Small unfiltered refracting telescopes, equipped with projection screen are recommended for standard observations, in order to avoid artificial reduction in the observed solar diameter due to filtering effects. Preliminary data reductions on eclipses of 1995 India and 1998 Caribbean, and on 2004 Venus Transit are also presented.

    "Nudge, or nudging, refers to a policy approach inspired by behavioral sciences: it promotes the conducts identified as desirable by regulators without applying prohibition and coercion. This approach has gained a lot of momentum in the domain of health policies. Policy strategies based on behavioral insights appear ideal as to implementing healthier life styles and public health programs while minimizing compliance costs: from organ donation to food choices, from fighting obesity and chronic diseases to screening policies. Nudging, however, is not exempt from problems, especially in the sector of health, where individual free and informed consent constitutes a founding principle. Cancer screening programs, and especially breast cancer population tests, represent an interesting example for nudging strategies which have been widely applied but have also raised serious criticisms. Despite having been widely adopted by health systems, from the United States to the European Union, breast cancer screening programs keep raising debates about their actual impact on reducing mortality, risks of overdiagnosing and unnecessary or harmful treatments. In challenging the validity of screening programs, these controversies also affect their efficacy. Nudging has therefore been seen as a potentially useful tool in increasing participation, even though the extent of its actual impact remains ambiguous and problematic. For nudging to represent a relevant, powerful policy instrument its legitimacy requirements need to be identified. These concern the "right place" of behavioral-based measures within the traditional regulatory framework. The "right place" of nudging in science-based policies is part of a broader rethinking of what is democracy in "knowledge-based societies", namely through which procedures democratic institutions validate and legitimize their normative choices depending on uncertain and controversial knowledge."

    INTRODUZIONE. Lo stress occupazionale è una delle principali cause di malattie professionali e di assenze da lavoro e genera costi sanitari e sociali molto elevati; la comprensione del problema è stata l'obiet- tivo di numerosi studi. Monitorare lo stress negli infermieri può essere uno strumento per chi ha la responsabilità della gestione delle risorse umane nel sistema sanitario. La ricerca infermieristica italiana si è occupata solo marginalmente di stress lavorativo infermieristico. Gli obiettivi di questo studio sono dunque: stimare la prevalenza di stress tra gli infermieri di tre ospedali, in modo da disporre di dati epidemiologici per valutare la necessità di interventi di prevenzione e di trattamento del fenomeno; analizzare eventuali fattori di rischio e fattori protettivi in modo da progettare interventi preventivi mirati.

    La finalità dello studio è quella di cercare di determinare i parametri indicativi di malignità paragonando caratteristiche demografiche e aspetti di benignità o malignità dei loro noduli determinati sui referti anatomo-patologici dopo tiroidectomia in pazienti con citologia FNAB sospetta per neoplasia follicolare. Lo studio è stato condotto su 152 casi di sospetto carcinoma follicolare in base ai risultati della FNAB. Sono stati presi in considerazione l’età, l’eventuale esposizione a radiazioni, livelli sierici di TSH ed i dati ecografici riguardo al numero, diametro, struttura interna, ecogenicità, caratteristiche dei margini, eventuale presenza di alone e di micro calcificazioni interne. Sono stati anche considerati i rilievi scintigrafici dei noduli. L’età media dei pazienti era 48,14 anni (da 20 a 71); 25 (16,5%) di sesso maschile e 127 (83,5%) femminile. La natura maligna era prevalente tra i pazienti con TSH di livello superiore al normale, che non ai livelli normali o inferiori. La presenza di calcificazioni intranodulari [rapporto differenziale: 3,1; 95% di intervallo di confidenza: 1,3-7,4], aumento della vascolarizzazione intranodulare [rapporto differenziale: 14,7; 95% di intervallo di confidenza: 1,4-147,7], assenza di segni di alone [rapport differenziale: 0,1; 95% di intervallo di confidenza: 0,04-0,8], e margini non ben definiti [rapport differenziale: 0,1; 95% di intervallo di confidenza: 0,49-0,3] erano i dati statisticamente significativi più comuni nei casi di malignità. Su questi dati si può concludere che su basi cliniche e su parametri ecografici è possibile fare previsioni sulla malignità di noduli tiroidei di natura indeterminata, ricordando che l’indagine ecografica è un mezzo semplice, facile e di scarso costo nella diagnostica dei noduli tiroidei.

    Il significato prognostico delle micrometastasi nel linfonodo sentinella nelle pazienti affette da carcinoma della mammella è ancora ampiamente dibattuto. Anche se, in assenza di univoche linee guida, nella pratica clinica la linfadenectomia ascellare in queste pazienti non viene più eseguita di routine. Abbiamo condotto uno studio retrospettivo su 746 patienti affette da carcinoma invasivo della mammella con linfonodi ascellari negativi, sottoposte a chirurgia conservativa o a mastectomia totale con biopsia del linfonodo sentinella. Le pazienti in cui è stata diagnostica la presenza di micrometastasi del linfonodo sentinella sono state considerate in due diversi gruppi. In un primo gruppo, trattato con linfadenectomia ascellare totale è stata valutata l’incidenza di metastasi a carico dei rimanenti linfonodi ascellari. Un secondo gruppo non ha ricevuto alcun trattamento aggiuntivo dell’ascella e le pazienti sono state seguite con controlli periodici clinico strumentali. In entrambi i gruppi è stata valutata l’incidenza di eventuali recidive ascellari. All’esame istologico estemporaneo ed al successivo esame istologico definitivo del linfonodo sentinella, in 51 pazienti (6,83%) sono state evidenziate micrometastasi, in 8 pazienti (1,07%) erano presenti cellule tumorali isolate. Quindici di queste pazienti sono state sottoposte a linfadenectomia ascellare totale. Solo in 2 casi (13,33%) sono state ritrovate metastasi a carico dei rimanenti linfonodi ascellari. Quarantaquattro pazienti non hanno ricevuto alcun trattamento aggiuntivo dell’ascella. In queste pazienti nessuna recidiva ascellare è stata registrata durante un follow-up medio di 65,3±9,65 mesi (range 42-78 mesi). Sulla base dei risultati ottenuti in questo studio ed in linea con alcuni recenti trials randomizzati si ci sentiamo di concludere che la linfadenectomia ascellare può essere evitata nei casi con micrometastasi nel linfonodo sentinella. Una sua eventuale indicazione può essere

    Scopo. Determinare la prevalenza di cyberstalking tra gli infermieri italiani e valutare il livello di ansia e depressione nelle vittime. Metodo. Da aprile a settembre 2014 è stato condotto uno studio multicentrico trasversale in un campione di infermieri italiani (n=997) utilizzando il questionario “Cyberstalking” per analizzare il fenomeno del cyberstalking. Ai partecipanti, che si sono autodefinite vittime di cyberstalking, è stato chiesto anche di compilare gli strumenti “Beck Depression Inventory” e “State-Trait Anxiety Inventory” per valutare, rispettivamente, i livelli di depressione ed ansia. Risultati. La prevalenza di cyberstalking tra gli infermieri italiani è risultata pari al 23.3%. Il 42.7% ha dovuto cambiare il proprio stile di vita e lavorativo. Il cyberstalker era prevalentemente di sesso maschile (52%) e, nel 49% dei casi, era un paziente. Le vittime hanno riferito moderati livelli di ansia (media=28.4, SD=23.2) e depressione (media=92.7, SD=18.3); i risultati hanno mostrato un aumento dei livelli di depressione negli infermieri esperti nell’utilizzo del computer, gestori di siti web o blog, e una correlazione negativa tra il livello di ansia e gli infermieri esperti (r = -0.264). Conclusioni. Il cyberstalking è un fenomeno che si riscontra frequentemente tra gli infermieri. Il rapporto infermiere - paziente gioca un ruolo centrale nello sviluppo del fenomeno e le vittime hanno riferito disordini correlati allo stress che influenzano la vita lavorativa. Questi risultati preliminari potrebbero sensibilizzare, i dirigenti ospedalieri, la politica e i centri antiviolenza al fine di sviluppare strategie risolutive a sostegno delle vittime.

    La pratica, universalmente riconosciuta, della ricerca e biopsia del linfonodo sentinella nella stadiazione dei tumori ha evidenziato una serie di situazioni anatomiche e fisiologiche che hanno consentito una più approfondita conoscenza del comportamento del flusso linfatico nel soggetto sano e nel paziente affetto da neoplasia. In particolar modo abbiamo concentrato la nostra attenzione sulle pazienti sottoposte a ricerca linfoscintigrafica del linfonodo sentinella in vista di interventi chirurgici per carcinoma mammario; abbiamo valutato statisticamente la sede in cui è stato reperito il LS e nell’eventualità di drenaggio in sedi anomale il percorso del flusso linfatico. Si è fatto riferimento, per questo studio, alla casistica del Dipartimento di Scienze Chirurgiche dell’Università La Sapienza di Roma maturata negli ultimi 2 anni. Lo scopo del nostro studio è stato quello di valutare statisticamente la sede del linfonodo sentinella, le possibilità di flussi linfatici in direzione non usuale e in questi casi dove, quando e perché. Ne sono emersi riscontri degni di analisi critica e considerazioni oggetto del presente lavoro.

    Costruito per chiara volontà del papa 70 anni dopo il caso Galileo, lo Gnomone Clementino è un grande telescopio solare che non fa uso di lenti a 92 anni dall’invenzione del cannocchiale. Queste due caratteristiche basterebbero da sole a giustificare l’interesse verso questo strumento. L’astronomia meridiana è alla base dell’astrometria e dell’astrofisica moderna. Lo Gnomone Clementino sta oggi all’astronomia, come il veliero “Amerigo Vespucci” sta alla Marina Italiana. E’ possibile svolgere ogni genere di osservazione e studio su questo strumento, e dal 2002 vi tengo lezioni teorico-pratiche del corso di Storia dell’Astronomia e La Terra nel Sistema Solare della Sapienza, Università di Roma, Facoltà di Lettere e Filosofia. Questo testo aggiunge alcuni tasselli alla ricerca storica sulla meridiana, appoggiandosi, com’è naturale, sulle spalle di giganti che mi hanno preceduto in questi studi. In particolare la misura dell’azimut della meridiana, ed il suo inquadramento tra gli strumenti simili ed alcuni studi di astrometria sui dati del 1701-1703 di Bianchini, che sono apparsi fin’ora soltanto su riviste specializzate ed in Inglese vengono qui proposti in Italiano e semplificati, per valorizzare sempre più questa straordinaria opera d’arte e di scienza.

Le SED sono state modellate utilizzando sia templates empirici di quasar di tipo I (Elvis et al. 1994; Richards et al. 2006) con diversi livelli di estinzione, sia un modello teorico (Fritz et al. 2006) in grado di vincolare i parametri fisici piu` importanti del toro stesso (ad esempio, lo spessore ottico del toro, l'angolo con cui viene osservata la sorgente e il covering factor). Per ciascuna sorgente del campione si e` stimata la luminosita` bolometrica nucleare (10^45-10^47 erg/s) e la correzione bolometrica k_(bol,2-10 keV), definita come il rapporto tra la luminosita` bolometrica e la luminosita` misurata in banda 2-10 keV. Infine, si evidenzia come l'utilizzo dei dati MIPS a 70 e 160 micron sia importante nel vincolare ulteriormente il modello di toro e, di conseguenza, nel fornire una migliore stima della luminosita` infrarossa e bolometrica.

    2016-06-01

    Over the past few decades, a growing body of evidence demonstrates that students learn best in engaging, interactive, collaborative, and inquiry-based environments. However, most college science classes are still taught with traditional methods suggesting the existing selection of research-based instructional materials has not widely transformed undergraduate education. SCALE-UP is a renovated pedagogy and classroom environment that has achieved a greater impact than most, used extensively throughout the United States and abroad. SCALE-UP is not a simple collection of lesson plans or a textbook that can be easily adopted, and instead instructors are encouraged to customize main pedagogical principles to their unique instructional situation. This flexibility along with promotion of instructor autonomy may have assisted its spread. This paper uses case studies of five successful secondary implementations in the United States to examine how instructors gather information about reform, create a curriculum, and achieve sustained use. Many people learned about research-based resources that formed the composite of their curricula through interpersonal connections. Time constraints and misunderstandings between developers and instructors limited which resources were chosen and how they were used. Once instructors created a "working form" of the curriculum, three out of five instructors did not make significant changes. This could lead to the preservation of a more conservative curriculum. Implications include that disseminators should articulate core principles of the reform that should be retained to uphold the integrity of the reform as well as the areas where adopters have flexibility to innovate. Strategically involving other secondary users in the dissemination process could facilitate important interpersonal exchanges that could provide an additional layer of support for faculty.

    Sommario INTRODUZIONE: Valutare l’utilità dell’eco-color Doppler (CDU) dei vasi epiaortici nei pazienti con vertigine periferica da causa sconosciuta. MATERAILI E METODI: Centocinquantasei pazienti (gruppo studio; 42 uomini e 114 donne; età media 61,86 ± 14,14) e 161 pazienti (gruppo controllo; 80 uomini e 81 donne; età media 62,31 ± 13,69) sono stati sottoposti a CDU dei vasi epiaortici. Sono stati valutati i seguenti parametri: presenza di placche ateromasiche a livello dell’arteria carotide (CA) comune e/o interna; spessore medio intimale (IMT) della CA comune; picco di velocità sistolica (PSV) e indice di resistenza (RI) a livello delle arterie vertebrali (VA).Sono stati utilizzati test parametrici (T-test) e non parametrici (Mann–Whitney U-test e Kolmogorov–Smirnov test). È stata eseguita un’analisi di regressione logistica per fornire un odds ratio indice di grandezza del rischio di vertigine. Sono state considerate variabili indipendenti (età, sesso), fattori di rischio vascolare (ipercolesterolemia, diabete, ipertensione) e variabili CDU (IMT, placche, PSV e RI). RISULTATI: Placche ed IMT > 1 mm sono stati trovati in 31 (19,8%) e 98 (62,8%) pazienti del gruppo di studio e in 43 (26,7%) e 125 (77,6%) pazienti del gruppo controllo. I test statistici, applicati a PSV e RI, non hanno dimostrato differenze significative (p-valore > 0,05). Alla regressione logistica le vertigini sono risultate associate ad età, sesso, ipercolesterolemia, diabete, ipertensione e IMT (p < 0,01), mentre placche, PSV ed RI non erano fattori significativi (p > 0,05). DISCUSSIONE: IMT è la sola variabile CDU significativamente associata alla vertigine, specialmente nelle classi di età inferiore (35-45 e 45-55) del gruppo studio.

    Introduzione: Per divenire dei professionisti qualificati, gli studenti infermieri sperimentano diverse esperienze di tirocinio clinico. L’opinione dello studente può essere considerata un indicatore della qualità dell’insegnamento e una percezione positiva dell’esperienza di tirocinio si correla strettamente ad un apprendimento efficace. La scala CLES+T (Clinical Learning Environment and Supervision plus Nurse Teacher) è lo strumento psicometrico “gold standard” per valutare la qualità dell’ambiente di apprendimento clinico. Scopo: Valutare la qualità dell’ambiente di apprendimento clinico mediante la scala (CLES+T) ed evidenziare significative correlazioni inerenti le caratteristiche degli studenti, del modello tutoriale e dell’ambiente clinico. Metodo: Il 4 marzo 2013, durante una convocazione plenaria, è stata somministrata la scala CLES+T ai 242 studenti del 2° e 3° anno del Corso di Laurea in Infermieristica di Modena (Università di Modena e Reggio Emilia). Tutti i risultati sono stati statisticamente analizzati (Test della mediana). Risultati: Tutti i valori mediani si sono attestati ad un livello “4” (scala di Likert). La valutazione ottenuta dallo studente al termine del tirocinio clinico è l’unica variabile statisticamente correlata ai punteggi della scala, più il voto è basso peggiore risulta la valutazione dell’esperienza di tirocinio. In base all’opinione degli studenti le aree cliniche pediatriche e critiche hanno valutazioni più elevate. Conclusioni: Le valutazioni degli studenti erano uniformemente positive ed erano correlate al voto finale di tirocinio. Un clima di apprendimento positivo è stato considerato molto importante in questo studio. Questi risultati suggeriscono che un ambiente di apprendimento clinico favorevole e non ostile può influenzare gli esiti dell’apprendimento degli studenti. Concludiamo affermando che la scala CLES+T può essere uno strumento utile per esplorare il clima in tutte le

    Si intende qui descrivere il sistema di sorveglianza sugli effetti sulla salute (SpoTT) dell'inquinamento ambientale nelle aree circostanti l'inceneritore di Torino. SPoTT ha 3 linee di attività: 1. monitoraggio epidemiologico degli effetti a breve termine attraverso analisi temporali e misura della correlazione tra livelli giornalieri di emissioni dell'impianto e andamento degli eventi individuati dagli archivi dei dimessi (SDO), di pronto soccorso e di mortalità; sono coinvolti coloro che nel 2013-2018 risiedevano nell'area di ricaduta delle emissioni; 2. sorveglianza epidemiologica degli effetti a lungo termine, stimando tassi standardizzati di mortalità e morbosità; a ogni soggetto è attribuito il valore stimato di esposizione cumulato nel tempo caratteristico della residenza anagrafica; le informazioni sulla salute sono reperite dagli archivi SDO, di mortalità e dai certificati di assistenza al parto; sono studiati due decenni pre-post l'avvio dell'impianto: 2003-2012 e 2013-2022; 3. monitoraggio biologico con misurazione pre-post di metalli, PCDD/F, PCB, OH-IPA; sono coinvolti 196 residenti esposti e 196 di controllo di 35-69 anni, campionati a caso dalle anagrafi comunali; sono effettuate misure di funzionalità endocrina e respiratoria, pressione arteriosa, rischio cardiovascolare; l'esposizione cumulativa sarà stimata per ciascuna persona campionata integrando l'indirizzo di residenza, il tempo di permanenza in ciascun indirizzo e i dati ricavati dai modelli di ricaduta; sarà costituita una biobanca per future indagini di laboratorio; sono coinvolti anche 20 allevatori e i lavoratori dell'impianto. Una quarta linea di attività, non descritta in questo articolo, riguarda il monitoraggio della salute dei lavoratori addetti all'impianto. SPoTT è il primo studio in Italia su inceneritori e salute che adotta un disegno di studio longitudinale di adeguata potenza sia per i residenti sia per i lavoratori. I primi risultati sono attesi nel corso del 2016.

    Il mesotelioma peritoneale cistico è un tumore raro. Si tratta di un tumore benigno, che tuttavia va incontro a recidive locali post-chirurgiche in oltre il 50% dei casi. È proprio a seguito di recidive ricorrenti che si possono determinare trasformazioni maligne di questa neoplasia, come descritto in Letteratura. Nel Giugno del 2004 un paziente di 73 anni è giunto presso la nostra struttura con una tumefazione addominale causa di dolore gravativo: si trattava di una massa di 16 cm, la cui struttura, agli esami strumentali (ecografia, TC con m.d.c. e RMN), appariva pluricistica. Attraverso una laparotomia mediana si è provveduto alla sua rimozione e il paziente è stato dimesso in VIII giornata post-operatoria senza complicanze. L’esame istologico, corredato da studio immunoistochimico e di microscopia elettronica, ha consentito di porre diagnosi di mesotelioma peritoneale pluricistico in trasformazione maligna. D’accordo con gli oncologi, in considerazione della scarsa efficacia dei trattamenti adiuvanti e della scarsità dei dati riportati in Letteratura sull’argomento, si è deciso di sottoporre il paziente unicamente ad uno stretto follow-up, con esecuzione di ecografia addominale ogni sei mesi e TC addominale ogni anno. Ad oggi, dieci anni dopo il trattamento, il paziente, di 83 anni, gode di un discreto stato di salute e non si sono verificate riprese o recidive di malattia, né locali, né a distanza. Oltre al fatto di essere risultato maligno alla sua prima manifestazione e non dopo ripetute recidive, il caso presenta altre particolarità: il mesotelioma peritoneale cistico, infatti, solitamente colpisce soggetti di sesso femminile (con un rapporto F:M di 4,5:1) ad un’età media di 60 anni, mentre il caso descritto riguarda un soggetto di sesso maschile di 73 anni. La nostra osservazione dimostra la possibilità che il mesotelioma peritoneale vada incontro a trasformazioni maligne già alla sua prima manifestazione e non esclusivamente dopo

    The purpose of this work is to obtain the curve of rotation of the Milky Way, to map the spiral structure of the Galaxy and to determine its integral mass. This is done through the study of the galactic neutral hydrogen concentration. We used the radio telescope Salsa Onsala Vale',a 2.3 m diameter parabolic dish, built by the Onsala Space Observatory at the Chalmers University of Technology in Sweden. Theutilized data are referred to several observations performed between December 22nd 2011 and January 6th 2012. For the data processing, the software SalsaJ was used. The result of this study confirms that the rotation velocity of the Galaxy, far away from the galactic center, does not decrease, but remains almost the same. The distribution of the neutral hydrogen is not uniform: it is concentrated in filamentary structures which are considered an evidence of the Milky Way spiral structure.

    Dating the crucifixion on friday 3 April 33, when, at sunset a partially eclipsed Moon rised allows to interprete the speech of Saint Peter (Acts 2:20=Joel 3:4) on the day of Pentecost as including an account of this eclipse, as fulfillment of the Scriptures. Few minutes later the apparition of a third star of medium magnitude stated the beginning of the sabbatical rest: before that time Jesus has been buried, wrapped into the shroud. The observations of the equinoctial moonrise from the Mount of Olives on September 2013 are strongly in favour of the hypotehsis of possible observation of the lunar eclipse of 33 AD by Jewish people, as well as the sunrises observed from the Temple Institute terrace in Southern-East Jerusalem demonstrated that this eclipse could have been seen from Jerusalem. The depression of the horizon and the refraction allow to see Sun and Moon more than 1 degree below the geometrical horizon in the azimuthal direction ranging from 90 to 116, prologing to 16 minutes the duration of the partial lunar eclipse observed in 33AD. Texts of Matthew, Mark and Cyrillus of Jerusalem are also commented.

    Sommario INTRODUZIONE: All’ecografia con Mezzo di Contrasto (CEUS) dei tumori secondari epatici si evidenzia spesso un alone periferico ipervascolare, che non ha corrispondenza sull’immagine ecografica di base e non è ancora stato caratterizzato istologicamente. Lo scopo dello studio è di caratterizzare tale alone al fine di determinare se sia necessario includerlo nel volume di necrosi pianificato. MATERIALI E METODI: Questo studio prospettico ha incluso 25 pazienti inviati per terapia termo-ablativa di tumori secondari epatici. Prima del trattamento tutti i pazienti sono stati sottoposti a CEUS. Il diametro maggiore della lesione è stato determinato: pre-contrasto, durante la fase arteriosa e durante la fase venosa portale. I diametri delle lesioni pre e post-contrasto sono stati confrontati mediante il test di Turkey–Kramer. Due campioni bioptici sono stati prelevati con ago 21-gauge e analizzati istologicamente: 1) uno dalla zona centrale del tumore e 2) uno dall’alone periferico ipervascolare, identificato alla CEUS solamente nella fase arteriosa. RISULTATI: Il diametro massimo medio delle lesioni è risultato (±deviazione standard): 2,67 ± 1,2 cm pre-contrasto; 3,50 ± 1,4 cm in fase arteriosa; 2,71 ± 1,2 cm in fase venosa. La differenza media tra il diametro massimo pre-contrasto e in fase arteriosa è risultata di 0,84 ± 0,45cm (p<0,0001). All’esame istologico, 24/25 campioni (96%) hanno dimostrato flogosi senza evidenza di tumore microscopico. DISCUSSIONE: L’alone ipervascolare periferico è costituito da infiltrato infiammatorio, non da tessuto tumorale. Esistono evidenze in letteratura che l’infiammazione cronica promuova la neovascolarizzazione e la produzione di fattori di crescita per le cellule neoplastiche. Sembra quindi opportuno includere completamente l’alone ipervascolare periferico evidente alla CEUS nel volume di termo-ablazione.

    Scopo di questo studio è quello di valutare i test di funzione tiroidea per indagare se una soluzione di Povidone- Iodine (PI) al 10%, che usiamo nella diluizione 1/5 con 0,9% NaCl in area addominale durante interventi puliti- contaminati, contaminati e sporchi in caso di idatidosi in organi parenchimatosi, al fine di evitare la formazione di ascessi e la disseminazione, raggiunge la circolazione sistemica. In questo studio sono stati inclusi 7 uomini e 6 donne in maniera prospettica. L’età media era di 33,69 (± 13.49). Preoperatoriamente ed al terzo giorno postoperatorio sono stati dosati i livelli ormonali di TSH, T3 libero (FT3) e T4 libero (FT4). È stata presa nota della quantità di PI usata per ogni paziente. Dall’analisi statistica non sono risultati valori significativamente differenti tra il preoperatorio ed il postoperatorio relativamente al livello degli ormoni tiroidei (preTSH vs postTSH: p= 0.984; preFT3 vs postFT3: p= 0.101; preFT4 vs postFT4: p=0.146). Così si è dimostrato che la dose di PI usata è efficace e non entra, o quanto meno a livello piuttosto basso, nella circolazione sistemica. I pazienti in cui tale procedura è stata usata non sono andati incontro in questa nostra esperienza ad ascessi addominali o aderenze intestinali. Raccomnadiamo dunque l’uso di queste dosi suggerite di PI in caso di perforazioni intestinali o ascessi, o in caso di possibile rischio di disseminazione in area intraaddominale di cisti idatidee.

Scopo del nostro studio è stato valutare il ruolo dell’ecografia nella diagnosi differenziale di dolore addominale in un reparto di medicina interna. Materiali e metodi: Abbiamo condotto un’analisi retrospettiva di 248 ecografie addominali eseguite per dolore addominale nel nostro centro. Per ogni esame, sono stati registrati i dati inseriti nel modulo di richiesta e i reperti ecografici che potevano essere considerati correlati a dolore addominale. Risultati: In 105 pazienti (42%) l’ecografia dell’addome ha rilevato un reperto ecografico rilevante ed è stata quindi considerata positiva. Un’alta percentuale di pazienti era anziana (>65 anni, 52%) e grande anziana (>80 anni, 24%): questi soggetti avevano percentuale significativamente maggiore di esami ecografici positivi. La percentuale di indagini positive non è risultata significativamente diversa tra quelle eseguite per dolore addominale localizzato e non localizzato. Specifiche localizzazioni di dolore addominale erano associate a determinati reperti ecografici, come masse epatiche, masse ovariche e calcolosi renale, mentre dolore addominale non localizzato era associato a reperti ecografici di versamento liquido addominale e anse intestinali distese da fluido. DISCUSSIONE: Un’alta percentuale di indagini ecografiche ha identificato condizioni che potrebbero causare dolore addominale. Il valore diagnostico dell’ecografia addominale è stato maggiore in pazienti anziani e grandi anziani. Quando viene richiesta un’ecografia addominale, l’esame dovrebbe sempre essere valutato nell’ambito nel contesto clinico. Il clinico dovrebbe essere consapevole della grande potenzialità dell’ecografia addominale nella diagnosi delle diverse cause di

    Sommario SCOPO: L'appendicite acuta è una delle urgenze chirurgiche addominali più comuni. Se non trattata, può rapidamente progredire verso complicanze severe, quali la perforazione e la peritonite. Spesso i chirurghi optano per un intervento chirurgico precoce anche in caso di diagnosi solo probabile, con il rischio di eseguire una quota importante di appendicectomie inutili. Lo scopo dello studio è di analizzare la nostra esperienza con la diagnosi integrata clinico-ultrasonografica dell'appendicite acuta. MATERIALI E METODI: Durante il periodo gennaio 1999-dicembre 2006 1447 pazienti sono stati sottoposti a valutazione clinica, a conta leucocitaria, dosaggio della proteina C reattiva ed ecografia addominale. È stata utilizzata la tecnica ecografia di compressione graduale, con sonda ad alta frequenza. RISULTATI: È stata formulata diagnosi ecografica di appendicite acuta in 368 pazienti (25%). Ulteriori 8 pazienti sono stati operati sulla base del solo giudizio clinico. Abbiamo osservato 7 casi di falsi positivi ecografici. In 1079 (75% del totale) pazienti è stato espresso un giudizio diagnostico negativo per appendicite acuta: in 173 di essi (12%) è stata formulata una diagnosi diversa. I restanti 906 pazienti sono stati sottoposti a controllo clinico fino alla risoluzione della sintomatologia, senza alcuna complicanza. I nostri risultati hanno dimostrato una sensibilità dell'ecografia del 98%, una specificità del 99%, un valore predittivo positivo del 98% e un valore predittivo negativo del 99%. L'accuratezza diagnostica globale è stata del 99%. CONCLUSIONI: La diagnosi integrata (clinica, di laboratorio ed ecografica) dell'appendicite acuta consente una diagnosi sicura, con risparmio di risorse evitando il ricorso ad appendicectomie inutili.

    Le ernie giganti sono rare nei Paesi sviluppati ed ancora più raramente sono associate ad altre ernie della parete addominale, come un’ernia inguinale controlaterale o un’ernia ombelicale. La presenza di più difetti di parete facilità il riposizionamento in addome del contenuto di una voluminosa ernia inguinale senza compromettere la funzionalità cardiorespiratoria, ma il rischio di intasamento o strozzamento intestinale negli altri orifizi erniari aumenta. In letteratura non esistono opinioni convergenti se riparare simultaneamente o in maniera sequenziale, cioè in maniera distanziata nel tempo, le diverse ernie di parete, quando sono associate ad un’ernia gigante. Riportiamo in questo lavoro il caso clinico di un uomo di 60 anni, italiano, che si recò nel nostro ambulatorio di chirurgia lamentando da molti anni la presenza di un’ernia inguinale gigante associata ad un’ernia inguinale controlaterale ed un’ernia ombelicale. Il paziente alla visita presentava difficoltà di deambulazione, ma non riferiva disturbi di canalizzazione. Aveva diverse comorbidità e tra queste quella più importante era una insufficienza respiratoria severa. Dopo un accurato studio cardiologico, respiratorio e metabolico il paziente fu sottoposto a riparazione delle ernie a partire da quella gigante, in maniera sequenziale ed in anestesia spinale secondo la tecnica di Lichtenstein. L’ernia ombelicale fu riparata per ultima con tecnica diretta, senza protesi, ed anch’essa in anestesia spinale. Il decorso operatorio fu regolare dopo i tre interventi e non si ebbe alcuna complicanza respiratoria, cardiologica né di canalizzazione. In conclusione riteniamo che nei pazienti con importanti comorbidità la riparazione di un’ernia gigante associata ad altre ernie di parete debba avvenire in maniera sequenziale, monitorando con attenzione la canalizzazione e soprattutto il progressivo adattamento dei visceri in addome attraverso la palpazione degli orifizi erniari.

    Scopo. Descrivere l'immagine dell'infermiere delineata da uno dei principali quotidiani nazionali. Metodo. Studio retrospettivo condotto attraverso l'analisi degli articoli pubblicati nel periodo compreso tra il 1906 e il 2005 sul quotidiano nazionale “La Stampa”. Risultati.Dall'analisi dei 2017 articoli sono emerse 11 categorie tematiche. Gli articoli a maggior occorrenza sono stati quelli relativi alla tematica “cronaca”, che hanno registrato un importante incremento a partire dalla seconda metà degli anni '80, seguiti da “condizioni di lavoro”, che hanno mostrato massima diffusione a partire dagli anni '90. Gli articoli a minore occorrenza, invece, sono stati quelli riguardanti “estetica” e “concorsi”. Oltre la metà degli articoli inerenti la “carenza infermieristica” riferivano di disservizi da essa provocati. La quasi totalità degli articoli relativi a casi di “malasanità” evidenziava l'inadeguata assistenza erogata dagli infermieri con un trend di pubblicazione omogeneo a partire dagli anni '50. Gli articoli categorizzati nella tematica “carenza infermieristica”, “innovazione”, e “formazione”, hanno avuto la loro massima diffusione a partire dagli anni '90. Conclusioni. L'analisi condotta attraverso gli articoli apparsi sul quotidiano “La Stampa” ha consentito di leggere la storia della professione infermieristica come travagliata, fatta di conquiste professionali ottenute con lotte, rivendicazioni e innumerevoli cambiamenti, sia di tipo organizzativo che in ambito formativo, anche se gli articoli esaminati non sempre hanno contribuito a far apprezzare la professione per i suoi reali contenuti e contributi forniti al miglioramento della salute nella popolazione.

    Functional breads constitute an interesting alternative as vehicle of new essential fatty acids sources. The aim of this study was to improve the fatty acids (FA) profile of bakery products, producing breads with low saturated fatty acid (SFA) content and with high polyunsaturated fatty acid (PUFA) content, through partial substitution of wheat flour by other ingredients (soy flour, flax flour, and wheat bran) and to analyze the effect of this change on the technological, rheological, and sensorial characteristics of breads. Flaxseed flour (FF), soybeans flour (SF), or wheat bran (WB) was used to replace 50, 100, and 150 g kg−1 of wheat flour (WF) in breads. FF or SF produced a decrease in monounsaturated and SFA and an increase of PUFA in these breads. Furthermore, breads replaced with FF presented considerable increase in the content of n3 FA, while, SF or WB contributed to rise of linoleic and oleic FA, respectively. The substitution percentage increase of FF, SF, or WB to formulation produced changes in the colour, rheological, textural, and technological characteristics of breads. This replacement resulted in improved lipid profile, being breads with 50 g kg−1 SF, the better acceptance, baking features, and enhanced fatty acid profile. PMID:25478592

    The aim of statistical analyses in cluster investigations is to estimate the probability that the aggregation of cases could be due to chance. As a result of several statistical problems - including the post-hoc nature of the analysis and the subjective nature of implied multiple comparisons - this cannot be carried out with any certainty. In cluster investigations, expert opinion should carry much more weight than P-values, which are exceedingly difficult to interpret.

    Lo scopo dello studio è stato valutare l’incidenza di complicanze correlate alla calcolosi della colecisti in pazienti in lista d’attesa per l’intervento di colecistectomia e quantificare le implicazioni economiche di quest’attesa in termini di costi sanitari relativi agli esami ematochimici, strumentali, alla degenza, all’intervento chirurgico e alle terapie somministrate. La popolazione oggetto dello studio è stata di 86 pazienti, 39 uomini e 47 donne, inseriti in lista d’attesa per intervento chirurgico di colecistectomia in un periodo compreso fra aprile 2007 e aprile 2010. Di tali pazienti sono stati raccolti dati anagrafici, la durata del tempo d’attesa, dettagli sugli accessi in PS ed eventuali ricoveri durante l’attesa, esami e terapie eseguite, il tipo di intervento chirurgico effettuato e i giorni di degenza. È stato fatto uno studio comparativo di natura economica tra tre gruppi di pazienti: A: asintomatici durante l’attesa, B: complicati ma non operati in urgenza, C: complicati e operati in regime d’urgenza. Utilizzando il tariffario regionale delle prestazioni di assistenza specialistica ambulatoriale e quello delle prestazioni di assistenza ospedaliera per acuti erogate in regime di ricovero diurno abbiamo stimato che un singolo paziente complicato ma non operato in regime d’urgenza abbia determinato un ingente spesa per il sistema sanitario ( gruppo B: circa 3513,2 €) circa 1.9 volte in più se paragonata a un paziente che durante l’attesa non abbia sviluppato complicanze ( gruppo A: circa 1.849,4 €) o 1.36 volte in più di un paziente precocemente operato in regime d’urgenza (gruppo c: circa 2.584,6 €).

    La pancreatite rimane ad oggi la maggiore complicanza dell’ERCP nonostante numerose misure tese alla sua prevenzione siano state proposte negli anni. La sua incidenza è del 3.5% e raggiunge in alcune serie di casi anche il 25%; solitamente è lieve-moderata nel 90%. La stratificazione dei pazienti in base al grado di rischio è necessaria per destinare i casi più complessi a centri di terzo livello presenti nel territorio; per far questo, un’analisi dei possibili fattori di rischio è stata originariamente proposta da Freeman ed è poi stata modificata dall’ESGE sulla base dei contributi dei singoli centri, con importanti modifiche. Il presente studio analizza l’incidenza di pancreatite post- ERCP in un centro di terzo livello analizzando, sulla scorta dei fattori di rischio proposti, l’aderenza dei dati. Negli anni 2012-2013, 492 pazienti sono stati sottoposti ad ERCP da due esperti endoscopisti. Secondo le classificazioni di Freeman e Cotton sono state osservate 14 PEP (2.8%), di cui 6 lievi, 4 moderate e 4 severe. È stata condotta un’analisi multivariata che ha evidenziato come fattori di rischio l’elevato numero di tentativi di incannulamento della via biliare e l’iniezione di mezzo di contrasto nel dotto pancreatico; sono risultati fattori protettivi l’early pre-cut e il fallimento della procedura con la sua interruzione. Nella discussione sono state inoltre brevemente analizzate le varie misure profilattiche, quali il posizionamento di protesi pancreatiche e l’utilizzo dei FANS. È interessante notare come i nostri risultati rafforzino gli ultimi orientamenti nel management dell’ERCP, circa l’utilizzo della tecnica di incannulamento filo-guidato e del pre-cut; questi infatti riducono il numero di tentativi di incannulamento ed il conseguente trauma alla papilla promuovendo un incannulamento biliare selettivo e prevenendo l’iniezione di mezzo di contrasto nel dotto pancreatico.

    Il presente studio raffronta due gruppi di pazienti affetti da adenocarcinoma dolo-rettale, sottoposti rispettivamente a colectomia con tecnica open e a videolaparoscopia, mettendone in luce benefici e svantaggi. Si tratta di un’analisi retrospettiva: dal gennaio 2003 e il dicembre 2006 sono stati reclutati 54 pazienti; di questi 26 operati in laparotomia e 28 in laparoscopia. Per la chirurgia laparotomica la durata media dell’intervento è stata di 177.9 minuti (tempo chirurgico) e di 280.4 minuti (tempo di sala operatoria con un minimo di 110 ed un massimo di 360 minuti, con significative differenze in rapporto al tipo di chirurgia effettuata e la storia clinica del paziente. Per la chirurgia laparoscopica la durata media è stata di 293 minuti (range 135-520), con significative differenze dipendenti dalla porzione di intestino asportata. Il raffronto delle due tecniche chirurgiche, laparotomica versus lapsroscopica, ha rivelato alcune differenze. La durata della resezione è stata maggiore per la laparoscopia se confrontata con la tecnica tradizionale. Entrambi gli approcci rappresentano tecniche convenienti, sicure ed oncologicamente corrette. La laparoscopia mostra maggiori vantaggi in termini di controllo del dolore, assenza di estese cicatrici, riscontro di laparoceli e di degenza post operatoria comparata con la tecnica laparotomica.

    Sebbene la tecnica Mesh Plug rappresenti una procedura di indubbia efficacia nel trattamento dell’ernia inguinale, tuttora permangono dubbi in relazione alla storia naturale del plug. In particolare, il plug può andare incontro a coartazione (shrinkage) con formazione di un “meshoma” responsabile di una sintomatologia dolorosa cronica. Più raramente, il plug può migrare e provocare erosione delle strutture anatomiche circostanti. Nel passato sono stati proposti alcuni devices per cercare di risolvere il problema della migrazione; nessuno di questi, tuttavia, ha raggiunto la popolarità dei plug conici o a forma di fiore. Il presente lavoro riporta i risultati di uno studio pilota condotto con l’impiego di un nuovo device tridimensionale, il NeT Plug & Patch. I risultati dopo 12 mesi di follow-up, hanno dimostrato una ridotta incidenza di dolore postoperatorio e cronico, senza rischio di migrazione. Inoltre è stata registrata una compliance soddisfacente sia dei pazienti che degli operatori. La protesi NeT Plug & Patch ha dimostrato di poter realizzare un’ernioplastica semplice ed efficace per la riparazione dell’ernia inguinale.

    In 1972 Ente Nazionale Idrocarburi sponsored a program to holographically record the images of Venetian sculptural treasures for archival purposes. At Laboratorio San Gregorio, where the initial holography took place, G. Musumeci and K. Hempel suggested an experiment to determine whether the concentrated beam from the ruby holographic laser could ablate black-patina crusts from decaying marble. Initial success of a laser-divestment test on a Palazzo Ducale capital launched a search for funding to enable a full-scale laser-conservation demonstration. Later, at a Caltech reunion one of the author's physics professors (Carl Anderson, the discoverer of mu mesons and the positron), noting the prominence of the Venice Film Festival suggested our approaching the motion picture industry. Many years earlier Anderson's Caltech classmate, Frank Capra, had supported the research that led to the discovery of cosmic-ray-generated antimatter on Pikes Peak. (After Caltech, Capra had become a director at Columbia Studios.) Anderson's chance comment led to an introduction to producer Jack Warner at a festival screening of his "A Clockwork Orange" in Asolo. He and his friends contributed US$5000 toward the laser conservation of a marble relief of "The Last Supper" in the Porta della Carta of Venice. This work was conducted in 1980 under the direction of Arch. G. Calcagno. In 1981 it was found that the granite veneer or the newly completed Warner Center Tower had been stained during transit from the quarry. The Venice laser successfully restored the veneer, thereby returning the Warner Brothers' favor.

    Introduzione: La competenza è un elemento fondamentale quando si misura la capacità di infer- mieri o studenti di fornire assistenza infermieristica, ma non vi è consenso su ciò che realmente sia la competenza. Questo studio si propone di indagare i significati e i modelli di competenza infermieristica. Metodo: L’overview delle revisioni della letteratura e delle concept analysis è stata effettuata attraverso una ricerca su Pubmed, Cinahl e PsychINFO dal gennaio 2005 a settembre 2014, che includeva parole chiave come: Modello di competenza; Competenza professionale; Competenza infermieristica; Competenza. Risultati: Sono stati inclusi un totale di 14 articoli, provenienti dalla letteratura infermieristica sia in ambito formativo che clinico. È stato possibile individuare alcuni temi comuni negli arti- coli inclusi: la descrizione dei determinanti di competenza; la confusione intorno al concetto di competenza; la carenza nella valutazione delle competenze; la carenza nell’operazionalizzare il concetto di competenza. Conclusioni: I risultati forniscono una panoramica che, arricchita dalla letteratura proveniente dagli studi organizzativi, costituiscono la base concettuale di un modello integrato di compe- tenza infermieristica. Ulteriore ricerca empirica è necessaria per verificare le assunzioni teoriche.

    Introduzione. Secondo l'Organizzazione Mondiale della Sanità (OMS) le cadute e i danni ad esse correlati sono una problematica prioritaria per i sistemi sanitari e sociali in Europa e nel mondo, soprattutto tenendo conto del rapido accrescersi dell'aspettativa di vita. Scopo: Obiettivo del presente studio è descrivere incidenza, cause e modalità di caduta nell’Azienda Sanitaria Locale Cuneo 1 (ASL CN1) in seguito all’accorpamento del 2008. Metodo: L’indagine si articola in due fasi: 1. definizione dell'atteso sulla base di letteratura ed altre realtà comparabili; 2. analisi del contesto realizzata attraverso esame delle schede di segnalazione delle cadute compilate tra 1 Luglio 2010 - 30 Giugno 2011. Risultati: L’incidenza delle cadute nel periodo in esame è dello 0.8% e nel 69% dei casi la causa è rappresentata dai fattori intrinseci, seguiti da quelli estrinseci (7.4%), organizzativi (5.4%) e quelli legati a difficoltà comunicative interprofessionali (3.1%). Conclusioni: Data l'eziologia multifattoriale delle cadute, l'approccio più efficace per ridurne l'incidenza è quello multidimensionale; si comprende quindi l'importanza di un'azione simultanea su tre livelli: organizzativo, staff/comunicazione e paziente.

    Microalbuminuria is a prognostic marker of cardiovascular disease and is related to metabolic syndrome (MetS). For this purpose, the authors examined the relationship of low grade albuminuria to MetS, using 4 current definitions and a MetS score. They studied 6650 consecutive, nondiabetic, hypertensive patients with normal microalbumin excretion. MetS was defined by Adult Treatment Panel III, American Heart Association, World Heart Organization, International Diabetes Federation criteria, and MetS Gruppo Italiano per lo Studio della Streptochinasi nell'Infarcto Miocardico (GISSI) score. Urine microalbumin concentration was measured after a 24-hour urine collection by immunonephelometry. By all definitions, hypertensive patients with MetS had higher microalbumin levels. Significantly higher microalbumin levels were observed as the number of metabolic components rose. After adjustment for systolic blood pressure, the strength of this association was reduced to a nonsignificant level. Microalbumin levels, within normal range, are increased in patients with MetS, irrespective of the definition criteria.

    OBIETTIVI: valutare e quantificare l'esposizione umana al mercurio (Hg) ed esplorare i fattori chiave che influenzano la contaminazione nelle popolazioni residenti in prossimità della Rada di Augusta, un'area a elevato rischio ambientale a causa degli effetti degli sversamenti incontrollati di Hg da parte di uno dei più grandi impianti cloro-soda d'Europa. DISEGNO: un campione di residenti nei comuni di Augusta, Priolo e Melilli (Sicilia orientale) è stato selezionato per lo studio di biomonitoraggio umano. Un questionario dettagliato è stato somministrato a ogni partecipante per raccogliere informazioni anagrafiche sulle abitudini di vita e alimentari. I livelli di Hg in sangue e capelli, usati come traccianti di esposizione a metilmercurio, sono stati messi in relazione al consumo di pesce locale. Il contenuto di Hg nelle urine è stato utilizzato per esplorare eventuali esposizioni atmosferiche a Hg inorganico. Una regressione lineare multivariata è stata applicata con l'obiettivo di esplorare i fattori che influenzano l'esposizione umana al Hg. L'approccio tossicocinetico è stato impiegato al fine di calcolare la dose settimanale provvisoria tollerabile ( provisional tolerable weekly intake, PTWI) e di predire le concentrazioni di Hg attese nel sangue degli individui con una dieta alimentare basata esclusivamente su pesce locale.
