    Riassunto Negli ultimi anni abbiamo assistito a un fiorire di novità cliniche e scientifiche sulla celiachia (CE), ma forse la novità più importante che influenzerà il futuro della ricerca e della clinica in questo campo riguarda la storia naturale della malattia. Per molti anni si è creduto che la predisposizione genetica e l’esposizione al glutine fossero necessarie e sufficienti allo sviluppo della CE. Studi recenti, però suggeriscono che la perdita di tolleranza al glutine possa apparire in qualsiasi momento della vita a seguito di altri elementi. Inoltre, diversi fattori ambientali conosciuti per il loro ruolo nell’influenzare la composizione della microflora intestinale sono anche stati considerati legati allo sviluppo della CE. Tra questi fattori sono inclusi la modalità di parto, la dieta dell’infante e l’uso di antibiotici. A tutt’oggi, nessuno studio longitudinale di ampia scala ha determinato se e come la composizione del microbioma e il suo profilo metabolomico possano influenzare la perdita di tolleranza al glutine e il successivo sviluppo della CE in soggetti geneticamente predisposti. In questo articolo descriviamo uno studio prospettico, multicentrico e longitudinale su infanti a rischio per la CE che utilizzerà diverse tecniche per approfondire il ruolo che il microbioma intestinale ha durante i primi passaggi dello sviluppo della malattia autoimmune.

    Pannus formation is a fundamental event in the pathogenesis of rheumatoid arthritis and its hypervascularisation seems to be crucial to the development of joint damage. High-resolution greyscale ultrasonography is a safe, quick, and inexpensive imaging tool that allows an accurate detection of even minimal morphostructural changes in patients with rheumatoid arthritis, including joint effusion, thickening of synovial membrane and bone erosions. More recently, power Doppler sonography has proved to be a reliable tool for semiquantitative assessment of the vascularity of the synovial tissue. The contrast-enhanced power Doppler sonography seems to be a helpful adjunct in assessing synovitis and the therapeutic response to the different therapies in patients with rheumatoid arthritis. The aim of this radiological vignette was to show a representative example of use of power Doppler sonography with contrast agent in assessing rheumatoid synovitis.

    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 independent prognostic impact of diabetes mellitus (DM) and prediabetes mellitus (pre-DM) on survival outcomes in patients with chronic heart failure has been investigated in observational registries and randomized, clinical trials, but the results have been often inconclusive or conflicting. We examined the independent prognostic impact of DM and pre-DM on survival outcomes in the GISSI-HF (Gruppo Italiano per lo Studio della Sopravvivenza nella Insufficienza Cardiaca-Heart Failure) trial. We assessed the risk of all-cause death and the composite of all-cause death or cardiovascular hospitalization over a median follow-up period of 3.9 years among the 6935 chronic heart failure participants of the GISSI-HF trial, who were stratified by presence of DM (n=2852), pre-DM (n=2013), and non-DM (n=2070) at baseline. Compared with non-DM patients, those with DM had remarkably higher incidence rates of all-cause death (34.5% versus 24.6%) and the composite end point (63.6% versus 54.7%). Conversely, both event rates were similar between non-DM patients and those with pre-DM. Cox regression analysis showed that DM, but not pre-DM, was associated with an increased risk of all-cause death (adjusted hazard ratio, 1.43; 95% CI, 1.28-1.60) and of the composite end point (adjusted hazard ratio, 1.23; 95% CI, 1.13-1.32), independently of established risk factors. In the DM subgroup, higher hemoglobin A1c was also independently associated with increased risk of both study outcomes (all-cause death: adjusted hazard ratio, 1.21; 95% CI, 1.02-1.43; and composite end point: adjusted hazard ratio, 1.14; 95% CI, 1.01-1.29, respectively). Presence of DM was independently associated with poor long-term survival outcomes in patients with chronic heart failure. URL: http://www.clinicaltrials.gov.

    Our aim was to describe the incidence and predictors of stroke in patients who have heart failure without atrial fibrillation (AF). We pooled 2 contemporary heart failure trials, the Controlled Rosuvastatin in Multinational Trial Heart Failure (CORONA) and the Gruppo Italiano per lo Studio della Sopravvivenza nell'Insufficienza cardiaca-Heart Failure trial (GISSI-HF). Of the 9585 total patients, 6054 did not have AF. Stroke occurred in 165 patients (4.7%) with AF and in 206 patients (3.4%) without AF (rates 16.8/1000 patient-years and 11.1/1000 patient-years, respectively). Using Cox proportional-hazards models, we identified the following independent predictors of stroke in patients without AF (ranked by χ(2) value): age (hazard ratio, 1.34; 95% confidence interval, 1.18-1.63 per 10 years), New York Heart Association class (1.60, 1.21-2.12 class III/IV versus II), diabetes mellitus treated with insulin (1.87, 1.22-2.88), body mass index (0.74, 0.60-0.91 per 5 kg/m(2) up to 30), and previous stroke (1.81, 1.19-2.74). N-terminal pro B-type natriuretic peptide (available in 2632 patients) was also an independent predictor of stroke (hazard ratio, 1.31; 1.11-1.57 per log unit) when added to this model. With the use of a risk score formulated from these predictors, we found that patients in the upper third of risk had a rate of stroke that approximated the risk in patients with AF. A small number of demographic and clinical variables identified a subset of patients who have heart failure without AF at a high risk of stroke. © 2015 American Heart Association, Inc.

    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.

    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.

    1998-10-23

    Java Analysis Studio is a desktop data analysis application aimed primarily at offline analysis of high-energy physics data. The goal is to make the application independent of any particular data format, so that it can be used to analyze data from any experiment. The application features a rich graphical user interface (GUI) aimed at making the program easy to learn and use, but which at the same time allows the user to perform arbitrarily complex data analysis tasks by writing analysis modules in Java. The application can be used either as a standalone application, or as a client for a remote Java Data Server. The client-server mechanism is targeted particularly at allowing remote users to access large data samples stored on a central data center in a natural and efficient way.

    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.

    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.

    1999-04-01

    We implemented a studio General Chemistry program as part of a school mandate to replace large lectures in all first-year courses by small studio classes (maximum of 60 students) that integrate the class, recitation, and laboratory experience. Hallmarks of this approach include focusing on the student as a problem solver and facilitating cooperative learning via group interactions. Approximately 900 students take two semesters of General Chemistry: 750 engineering students take a Chemistry of Materials course that adopted this approach in 1996 and the remaining 150 students take General Chemistry for science majors. Five instructors have been involved with the latter course during the last two years. Starting in 1996, these courses meet in two general chemistry suites that we designed to accommodate 60 students each in a studio classroom setting. Each suite is fully equipped for computer-assisted instruction in both the classroom and the adjoining laboratories.

    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.

    Digital technology in the recording industry has evolved and expanded, allowing it to be widely available to the public at a significantly lower cost than in previous years. Due to this fact, numerous home studios are either being built inside or converted from bedrooms, dens, and basements. Hobbyists and part-time musicians that typically do not have the advantage of a large recording budget operate the majority of these home studios. Along with digital equipment, acoustic treatment has become more affordable over the years giving many musicians the ability to write, record, and produce an entire album in the comfort of their own home without having to sacrifice acoustical quality along the way. Three separate case studies were conducted on rooms with various sizes, applications, and budgets. Acoustical treatment such as absorption, diffusion, and bass trapping were implemented to reduce the effects of issues such as flutter echo, excessive reverberation, and bass build-up among others. Reactions and subjective comments from each individual studio owner were gathered and assessed to determine how effective home studios can be on a personal and professional level if accurately treated acoustically.

  10. Binding of GID1 to DELLAs promotes dissociation of GAF1 from DELLA in GA dependent manner.

    Gibberellins (GAs) are important phytohormones for plant growth and development. DELLAs are members of the plant-specific GRAS protein family and act as repressors of GA signaling. DELLAs are rapidly degraded in the presence of GAs. GA-GID1-DELLA complexes are recognized and ubiquitinated by the SCF(SLY) complex. The sleepy1 (sly1) F-box mutant exhibits dwarfism and low-germination phenotypes due to high accumulation of DELLAs. Overexpression of GID1 in the sly1 mutant partially rescues these phenotypes without degradation of DELLAs suggesting that proteolysis independent regulation of DELLAs exists in GA signaling. But the molecular mechanisms of non-proteolytic regulation of DELLA are largely unknown. Recently we identified a DELLA binding transcription factor, GAI-ASSOCIATED FACTOR1 (GAF1). GAF1 also interacts with co-repressor TOPLESS RELATED (TPR) in nuclei. DELLAs and TPR act as coactivator and corepressor of GAF1, respectively. GAs converts the GAF1 complex from transcriptional activator to repressor via degradation of DELLAs. The overexpression of ΔPAM, lacking of DELLAs binding region of GAF1, partially rescue dwarf phenotypes of GA deficient or GA insensitive mutant. In this study, we investigate the relationship between non-proteolytic regulation of DELLAs and GA signaling via DELLA-GAF1 complex using modified yeast two-hybrid system.

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

    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.

  12. CS-Studio Scan System Parallelization

    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.

    DELLA proteins are transcriptional regulators present in all land plants which have been shown to modulate the activity of over 100 transcription factors in Arabidopsis, involved in multiple physiological and developmental processes. It has been proposed that DELLAs transduce environmental information to pre-wired transcriptional circuits because their stability is regulated by gibberellins (GAs), whose homeostasis largely depends on environmental signals. The ability of GAs to promote DELLA degradation coincides with the origin of vascular plants, but the presence of DELLAs in other land plants poses at least two questions: what regulatory properties have DELLAs provided to the behavior of transcriptional networks in land plants, and how has the recruitment of DELLAs by GA signaling affected this regulation. To address these issues, we have constructed gene co-expression networks of four different organisms within the green lineage with different properties regarding DELLAs: Arabidopsis thaliana and Solanum lycopersicum (both with GA-regulated DELLA proteins), Physcomitrella patens (with GA-independent DELLA proteins) and Chlamydomonas reinhardtii (a green alga without DELLA), and we have examined the relative evolution of the subnetworks containing the potential DELLA-dependent transcriptomes. Network analysis indicates a relative increase in parameters associated with the degree of interconnectivity in the DELLA-associated subnetworks of land plants, with a stronger effect in species with GA-regulated DELLA proteins. These results suggest that DELLAs may have played a role in the coordination of multiple transcriptional programs along evolution, and the function of DELLAs as regulatory 'hubs' became further consolidated after their recruitment by GA signaling in higher plants.

    2015-08-21

    Gibberellins (GA) are some of the most important phytohormones involved in plant development. DELLA proteins are negative regulators of GA signaling in many plants. In this study, the full-length cDNA sequences of three DELLA genes were cloned from Artemisia annua. Phylogenetic analysis revealed that AaDELLA1 and AaDELLA2 were located in the same cluster, but AaDELLA3 was not. Subcellular localization analysis suggested that AaDELLAs can be targeted to the nucleus and/or cytoplasm. Real-time PCR indicated that all three AaDELLA genes exhibited the highest expression in seeds. Expression of all AaDELLA genes was enhanced by exogenous MeJA treatment but inhibited by GA3 treatment. Yeast two-hybrid assay showed that AaDELLAs could interact with basic helix-loop-helix transcription factor AaMYC2, suggesting that GA and JA signaling may be involved in cross-talk via DELLA and MYC2 interaction in A. annua.

    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.

  13. 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.

  14. DELLA genes restrict inflorescence meristem function independently of plant height.

    2017-08-21

    DELLA proteins associate with transcription factors to control plant growth in response to gibberellin (1) . Semi-dwarf DELLA mutants with improved harvest index and decreased lodging greatly improved global food security during the 'green revolution' in the 1960-1970s (2) . However, DELLA mutants are pleiotropic and the developmental basis for their effects on plant architecture remains poorly understood. Here, we show that DELLA proteins have genetically separable roles in controlling stem growth and the size of the inflorescence meristem, where flowers initiate. Quantitative three-dimensional image analysis, combined with a genome-wide screen for DELLA-bound loci in the inflorescence tip, revealed that DELLAs limit meristem size in Arabidopsis by directly upregulating the cell-cycle inhibitor KRP2 in the underlying rib meristem, without affecting the canonical WUSCHEL-CLAVATA meristem size regulators (3) . Mutation of KRP2 in a DELLA semi-dwarf background restored meristem size, but not stem growth, and accelerated flower production. In barley, secondary mutations in the DELLA gain-of-function mutant Sln1d (4) also uncoupled meristem and inflorescence size from plant height. Our work reveals an unexpected and conserved role for DELLA genes in controlling shoot meristem function and suggests how dissection of pleiotropic DELLA functions could unlock further yield gains in semi-dwarf mutants.During gibberellic acid signalling, DELLAs restrict the size of the shoot apical meristem by targeting the cell cycle regulator KRP2. The roles of DELLAs in the shoot apical meristem and stem growth can be genetically uncoupled in Arabidopsis and barley.

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

    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.

    The Vanderbilt Institute for Clinical and Translational Research implemented the “Studio” Program in 2007 to bring together experts to provide free, structured, project-specific feedback for medical researchers. Studios are a series of integrated, dynamic, and interactive roundtable discussions that bring relevant research experts from diverse academic disciplines together to focus on a specific research project at a specific stage. Vanderbilt’s Clinical and Translational Science Award supports the program, which is designed to improve the quality and impact of biomedical research. In this article, the authors describe the program’s design, and they provide an evaluation of its first four years. After an investigator completes a brief online studio application, a studio “manager” reviews the request, assembles a panel of 3 to 6 experts (research faculty from multiple disciplines), and circulates the pre-review materials electronically. Investigators can request one of seven studio formats: hypothesis generation, study design, grant review, implementation, analysis and interpretation, manuscript review, or translation. A studio moderator leads each studio session, managing the time (90 minutes) and discussion to optimize the usefulness of the session for the investigator. Feedback from the 157 studio sessions in the first four years has been overwhelmingly positive. Investigators have indicated that their studios have improved the quality of their science (99%; 121/122 responses), and experts have reported that the studios have been a valuable use of their time (98%; 398/406 responses). To achieve the health goals of the 21st century, researchers from multiple disciplines must bridge their differences and together address the challenging problems that face us. -- The Institute of Medicine, 20011 PMID:22722360

  2. Color studio in crisis: embracing change

    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.

    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

    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.

  15. Fruit Growth in Arabidopsis Occurs via DELLA-Dependent and DELLA-Independent Gibberellin Responses[W][OA

    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.

    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

    2012-05-01

    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.

    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.

  20. DELLA protein function in growth responses to canopy signals.

    PubMed

    Djakovic-Petrovic, Tanja; de Wit, Mieke; Voesenek, Laurentius A C J; Pierik, Ronald

    2007-07-01

    Plants can sense neighbour competitors through light-quality signals and respond with shade-avoidance responses. These include increased shoot elongation, which enhances light capture and thus competitive power. Such plant-plant interactions therefore profoundly affect plant development in crowded populations. Shade-avoidance responses are tightly coordinated by interactions between light signals and hormones, with essential roles for the phytochrome B photoreceptor [sensing the red:far red (R:FR) ratio] and the hormone gibberellin (GA). The family of growth-suppressing DELLA proteins are targets for GA signalling and are proposed to integrate signals from other hormones. However, the importance of these regulators has not been studied in the ecologically relevant, complex realm of plant canopies. Here we show that DELLA abundance is regulated during growth responses to neighbours in dense Arabidopsis stands. This occurs in a R:FR-dependent manner in petioles, depends on GA, and matches the induction kinetics of petiole elongation. Similar interactions were observed in the growth response of seedling hypocotyls and are general for a second canopy signal, reduced blue light. Enhanced DELLA stability in the gai mutant inhibits shade-avoidance responses, indicating that DELLA proteins constrain shade-avoidance. However, using multiple DELLA knockout mutants, we show that the observed DELLA breakdown is not sufficient to induce shade-avoidance in petioles, but plays a more central role in hypocotyls. These data provide novel information on the regulation of shade-avoidance under ecologically important conditions, defining the importance of DELLA proteins and GA and unravelling the existence of GA- and DELLA-independent mechanisms.

    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.

    2017-05-01

    The implementation of daylighting strategies in buildings is a common aspect in architecture. However, due to the availability of inexpensive electricity, natural lighting strategies became insignificant, and been overlooked by designers. With the current concern over rapid increment on electricity cost, many designers now try to revitalized daylighting strategies in buildings. This includes educational buildings. In Malaysian cases, it is a norm that universities; especially during lecture and studio sessions, used artificial lighting throughout the day. Definitely, this is not parallel with the “green” aim made by the Government in the Malaysian Plan. Therefore, this paper aims to explore the impact of daylight strategies for educational studios in universities, by maximising the penetration of natural daylight into the space towards creating a more green-conducive studio. The paper review literature about the types, criteria and benefits of daylight strategies. This paper also presented a pilot study that has been performed in one university in Perak, Malaysia, by selecting architectural studios as the main subject.

  17. uVis Studio: an integrated development environment for visualization

    NASA Astrophysics Data System (ADS)

    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.

    2013-04-01

    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.

  12. 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.

    2014-03-01

    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.

  18. Bridging the gap between building science and design studios

    SciTech Connect

    Papamichael, Konstantinos; Pal, Vineeta

    2002-02-06

    Design studios and building science courses have been conducted independent of each other, mainly due to a lack of tools that allow quick and easy consideration of building science criteria, such as comfort and energy requirements, during the design process. Existing tools are not user-friendly and their use requires significant effort in gaining familiarity with the input requirements, understanding the modeling assumptions and interpreting the output. This paper is about the Building Design Advisor (BDA), an evolving computer-based tool intended to bridge the gap between design studios and building science considerations by addressing the above-mentioned limitations of existing tools. BDA allows automatic preparation of input files to multiple simulation tools while the user is working in a CAD environment. BDA automatically activates the relevant simulation tools when the user selects performance parameters to be computed and provides the results in a graphical form, allowing comparison of multiple design options with respect to multiple performance criteria. The paper includes considerations for the use of the BDA in the design studio and ends with a description of the current development efforts and future plans.

    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.

  7. 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.

    The Colorado School of Mines (CSM) has taught its first-semester introductory physics course using a hybrid lecture/Studio Physics format for several years. Based on this previous success, over the past 18 months we have converted the second semester of our traditional calculus-based introductory physics course (Physics II) to a Studio Physics format. In this talk, we describe the recent history of the Physics II course and of Studio at Mines, discuss the PER-based improvements that we are implementing, 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), failure rates, and exam scores. We also report on recent attempts to involve students in the department's Senior Design program with our course. Our ultimate goal is to construct one possible model for a practical and successful transition from a lecture course to a Studio (or Studio-like) course.

  8. 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

  13. 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.

  14. Lifting DELLA Repression of Arabidopsis Seed Germination by Nonproteolytic Gibberellin Signaling1[C][W][OPEN

    PubMed Central

    Ariizumi, Tohru; Hauvermale, Amber L.; Nelson, Sven K.; Hanada, Atsushi; Yamaguchi, Shinjiro; Steber, Camille M.

    2013-01-01

    DELLA repression of Arabidopsis (Arabidopsis thaliana) seed germination can be lifted either through DELLA proteolysis by the ubiquitin-proteasome pathway or through proteolysis-independent gibberellin (GA) hormone signaling. GA binding to the GIBBERELLIN-INSENSITIVE DWARF1 (GID1) GA receptors stimulates GID1-GA-DELLA complex formation, which in turn triggers DELLA protein ubiquitination and proteolysis via the SCFSLY1 E3 ubiquitin ligase and 26S proteasome. Although DELLA cannot be destroyed in the sleepy1-2 (sly1-2) F-box mutant, long dry after-ripening and GID1 overexpression can relieve the strong sly1-2 seed dormancy phenotype. It appears that sly1-2 seed dormancy results from abscisic acid (ABA) signaling downstream of DELLA, since dormant sly1-2 seeds accumulate high levels of ABA hormone and loss of ABA sensitivity rescues sly1-2 seed germination. DELLA positively regulates the expression of XERICO, an inducer of ABA biosynthesis. GID1b overexpression rescues sly1-2 germination through proteolysis-independent DELLA down-regulation associated with increased expression of GA-inducible genes and decreased ABA accumulation, apparently as a result of decreased XERICO messenger RNA levels. Higher levels of GID1 overexpression are associated with more efficient sly1 germination and increased GID1-GA-DELLA complex formation, suggesting that GID1 down-regulates DELLA through protein binding. After-ripening results in increased GA accumulation and GID1a-dependent GA signaling, suggesting that after-ripening triggers GA-stimulated GID1-GA-DELLA protein complex formation, which in turn blocks DELLA transcriptional activation of the XERICO inhibitor of seed germination.

  15. Auxin acts independently of DELLA proteins in regulating gibberellin levels.

    PubMed

    Reid, James B; Davidson, Sandra E; Ross, John J

    2011-03-01

    Shoot elongation is a vital process for plant development and productivity, in both ecological and economic contexts. Auxin and bioactive gibberellins (GAs), such as GA1, play critical roles in the control of elongation, along with environmental and endogenous factors, including other hormones such as the brassinosteroids. The effect of auxins, such as indole-3-acetic acid (IAA), is at least in part mediated by its effect on GA metabolism, since auxin up-regulates biosynthesis genes such as GA 3-oxidase and GA 20-oxidase and down regulates GA catabolism genes such as GA 2-oxidases, leading to elevated levels of bioactive GA 1. In our recent paper, we have provided evidence that this action of IAA is largely independent of DELLA proteins, the negative regulators of GA action, since the auxin effects are still present in the DELLA-deficient la cry-s genotype of pea. This was a crucial issue to resolve, since like auxin, the DELLAs also promote GA 1 synthesis and inhibit its deactivation. DELLAs are deactivated by GA, and thereby mediate a feedback system by which bioactive GA regulates its own level. However, our recent results, in themselves, do not show the generality of the auxin-GA relationship across species and phylogenetic groups or across different tissue types and responses. Further, they do not touch on the ecological benefits of the auxin-GA interaction. These issues are discussed below as well as the need for the development of suitable experimental systems to allow this process to be examined.

    DELLA proteins and phytohormone gibberellin act together to control convergence point of plant development. A gibberellin-bound nuclear receptor that interacts with the N-terminal domain of DELLA proteins is required for gibberellin induced degradation of DELLA proteins. N-terminal DELLA domain includes two conserved motifs: DELLA and VHYNP. However, their respective functions remain unclear. Meanwhile, the identification and detection of several bioactive gibberellins from the more than 100 gibberellin metabolites are overwhelmingly difficult for their similar structures. Using in vitro biochemical approach, our work demonstrates for the first time that the synthetic GAI N-terminal DELLA domain peptides have similar bioactive function as the expressed protein to interact with AtGID1a receptor. Furthermore, our results reveal that DELLA motif is vitally important region and DELLA segment is essentially required region to recognize AtGID1a receptor. Finally, based on bioactive GA-dependent of the interaction between AtGID1a and DELLA protein, we generated a new method that could identify and detect bioactive GAs accurately and rapidly with surface plasmon resonance assays.

    Engaging communities in research increases its relevance and may speed the translation of discoveries into improved health outcomes. Many researchers lack training to effectively engage stakeholders, whereas academic institutions lack infrastructure to support community engagement. In 2009, the Meharry-Vanderbilt Community-Engaged Research Core began testing new approaches for community engagement, which led to the development of the Community Engagement Studio (CE Studio). This structured program facilitates project-specific input from community and patient stakeholders to enhance research design, implementation, and dissemination. Developers used a team approach to recruit and train stakeholders, prepare researchers to engage with stakeholders, and facilitate an in-person meeting with both. The research core has implemented 28 CE Studios that engaged 152 community stakeholders. Participating researchers, representing a broad range of faculty ranks and disciplines, reported that input from stakeholders was valuable and that the CE Studio helped determine project feasibility and enhanced research design and implementation. Stakeholders found the CE Studio to be an acceptable method of engagement and reported a better understanding of research in general. A tool kit was developed to replicate this model and to disseminate this approach. The research core will collect data to better understand the impact of CE Studios on research proposal submissions, funding, research outcomes, patient and stakeholder engagement in projects, and dissemination of results. They will also collect data to determine whether CE Studios increase patient-centered approaches in research and whether stakeholders who participate have more trust and willingness to participate in research.

    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.

  2. OpenStudio: A Platform for Ex Ante Incentive Programs

    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.

    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.

    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.

    Problem Engaging communities in research increases its relevance and may speed the translation of discoveries into improved health outcomes. Many researchers lack training to effectively engage stakeholders, whereas academic institutions lack infrastructure to support community engagement. Approach In 2009, the Meharry-Vanderbilt Community-Engaged Research Core began testing new approaches for community engagement, which led to the development of the Community Engagement Studio (CE Studio). This structured program facilitates project-specific input from community and patient stakeholders to enhance research design, implementation, and dissemination. Developers used a team approach to recruit and train stakeholders, prepare researchers to engage with stakeholders, and facilitate an in-person meeting with both. Outcomes The research core has implemented 28 CE Studios that engaged 152 community stakeholders. Participating researchers, representing a broad range of faculty ranks and disciplines, reported that input from stakeholders was valuable and that the CE Studio helped determine project feasibility and enhanced research design and implementation. Stakeholders found the CE Studio to be an acceptable method of engagement and reported a better understanding of research in general. A tool kit was developed to replicate this model and to disseminate this approach. Next Steps The research core will collect data to better understand the impact of CE Studios on research proposal submissions, funding, research outcomes, patient and stakeholder engagement in projects, and dissemination of results. They will also collect data to determine whether CE Studios increase patient-centered approaches in research and whether stakeholders who participate have more trust and willingness to participate in research.

    In this study, we explore the strategic self-regulatory and motivational characteristics of students in studio-mode physics courses at three universities with varying student populations and varying levels of success in their studio-mode courses. We survey students using questions compiled from several existing questionnaires designed to measure students' study strategies, attitudes toward and motivations for learning physics, organization of scientific knowledge, experiences outside the classroom, and demographics. Using a person-centered approach, we utilize cluster analysis methods to group students into learning profiles based on their individual responses to better understand the strategies and motives of algebra-based studio physics students. Previous studies have identified five distinct learning profiles across several student populations using similar methods. We present results from first-semester and second-semester studio-mode introductory physics courses across three universities. We identify these five distinct learning profiles found in previous studies to be present within our population of introductory physics students. In addition, we investigate interactions between these learning profiles and student demographics. We find significant interactions between a student's learning profile and their experience with high school physics, major, gender, grade expectation, and institution. Ultimately, we aim to use this method of analysis to take the characteristics of students into account in the investigation of successful strategies for using studio methods of physics instruction within and across institutions.

    In response to canopy shade, plant vegetative structures elongate to gain access to light. However, the mechanism that allows a plastic transcriptional response to canopy shade light is not fully elucidated. Here we propose that the activity of PIF4, a key transcription factor in the shade signalling network, is modulated by the interplay between the BBX24 transcriptional regulator and DELLA proteins, which are negative regulators of the gibberellin (GA) signalling pathway. We show that GA-related targets are enriched among genes responsive to BBX24 under shade and that the shade-response defect in bbx24 mutants is rescued by a GA treatment that promotes DELLA degradation. BBX24 physically interacts with DELLA proteins and alleviates DELLA-mediated repression of PIF4 activity. The proposed molecular mechanism provides reversible regulation of the activity of a key transcription factor that may prove especially relevant under fluctuating light conditions.

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

    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.

    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.

    Arabidopsis De-etiolated 1 (DET1) is one of the key repressors that maintain the etiolated state of seedlings in darkness. The plant hormone gibberellic acid (GA) also participates in this process, and plants deficient in GA synthesis or signaling show a partially de-etiolated phenotype in darkness. However, how DET1 and the GA pathway work in concert in repressing photomorphogenesis remains largely unknown. In this study, we found that the abundance of DELLA proteins in det1-1 was increased in comparison with that in the wild-type plants. Mutation in DET1 changed the sensitivity of hypocotyl elongation of mutant seedlings to GA and paclobutrazol (PAC), an inhibitor of GA synthesis. However, we did not find obvious differences between det1-1 and wild-type plants with regard to the bioactive GA content or the GA signaling upstream of DELLAs. Genetic data showed that removal of several DELLA proteins suppressed the det1-1 mutant phenotype more obviously than GA treatment, indicating that DET1 can regulate DELLA proteins via some other mechanisms. In addition, a large-scale transcriptomic analysis revealed that DET1 and DELLAs play antagonistic roles in regulating expression of photosynthetic and cell elongation-related genes in etiolated seedlings. Taken together, our results show that DET1 represses photomorphogenesis in darkness in part by reducing the abundance of DELLA proteins. Copyright © 2015 The Author. Published by Elsevier Inc.

  18. The DELLA-CONSTANS Transcription Factor Cascade Integrates Gibberellic Acid and Photoperiod Signaling to Regulate Flowering.

    Gibberellin (GA) and photoperiod pathways have recently been demonstrated to collaboratively modulate flowering under long days (LDs). However, the molecular mechanisms underlying this collaboration remain largely unclear. In this study, we found that GA-induced expression of FLOWERING LOCUS T (FT) under LDs was dependent on CONSTANS (CO), a critical transcription factor positively involved in photoperiod signaling. Mechanistic investigation revealed that DELLA proteins, a group of crucial repressors in GA signaling, physically interacted with CO. The DELLA-CO interactions repressed the transcriptional function of CO protein. Genetic analysis demonstrated that CO acts downstream of DELLA proteins to regulate flowering. Disruption of CO rescued the earlier flowering phenotype of the gai-t6 rga-t2 rgl1-1 rgl2-1 mutant (dellap), while a gain-of-function mutation in GA INSENSITIVE (GAI, a member of the DELLA gene) repressed the earlier flowering phenotype of CO-overexpressing plants. In addition, the accumulation of DELLA proteins and mRNAs was rhythmic, and REPRESSOR OF GA1-3 protein was noticeably decreased in the long-day afternoon, a time when CO protein is abundant. Collectively, these results demonstrate that the DELLA-CO cascade inhibits CO/FT-mediated flowering under LDs, which thus provide evidence to directly integrate GA and photoperiod signaling to synergistically modulate flowering under LDs. © 2016 American Society of Plant Biologists.

    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.

    The phytohormone gibberellin and the DELLA proteins act together to control key aspects of plant development. Gibberellin induces degradation of DELLA proteins by recruitment of an F-box protein using a molecular switch: a gibberellin-bound nuclear receptor interacts with the N-terminal domain of DELLA proteins, and this event primes the DELLA C-terminal domain for interaction with the F-box protein. However, the mechanism of signalling between the N- and C-terminal domains of DELLA proteins is unresolved. In the present study, we used in vivo and in vitro approaches to characterize di- and tri-partite interactions of the DELLA protein RGL1 (REPRESSOR OF GA1-3-LIKE 1) of Arabidopsis thaliana with the gibberellin receptor GID1A (GIBBERELLIC ACID-INSENSITIVE DWARF-1A) and the F-box protein SLY1 (SLEEPY1). Deuterium-exchange MS unequivocally showed that the entire N-terminal domain of RGL1 is disordered prior to interaction with the GID1A; furthermore, association/dissociation kinetics, determined by surface plasmon resonance, predicts a two-state conformational change of the RGL1 N-terminal domain upon interaction with GID1A. Additionally, competition assays with monoclonal antibodies revealed that contacts mediated by the short helix Asp-Glu-Leu-Leu of the hallmark DELLA motif are not essential for the GID1A–RGL1 N-terminal domain interaction. Finally, yeast two- and three-hybrid experiments determined that unabated communication between N- and C-terminal domains of RGL1 is required for recruitment of the F-box protein SLY1. PMID:21323638

  19. 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.

  3. 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.

    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.

    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.

    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. Copyright © 2014 Elsevier Ltd. All rights reserved.

    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

    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

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

    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.

  11. JUB1 suppresses Pseudomonas syringae-induced defense responses through accumulation of DELLA proteins

    ABSTRACT Phytohormones act in concert to coordinate plant growth and the response to environmental cues. Gibberellins (GAs) are growth-promoting hormones that recently emerged as modulators of plant immune signaling. By regulating the stability of DELLA proteins, GAs intersect with the signaling pathways of the classical primary defense hormones, salicylic acid (SA) and jasmonic acid (JA), thereby altering the final outcome of the immune response. DELLA proteins confer resistance to necrotrophic pathogens by potentiating JA signaling and raise the susceptibility to biotrophic pathogens by attenuating the SA pathway. Here, we show that JUB1, a core element of the GA - brassinosteroid (BR) - DELLA regulatory module, functions as a negative regulator of defense responses against Pseudomonas syringae pv. tomato DC3000 (Pst DC3000) and mediates the crosstalk between growth and immunity.

    DELLA proteins positively regulate nitrogen deficiency-induced anthocyanin accumulation through directly interaction with PAP1 to enhance its transcriptional activity on anthocyanin biosynthetic gene expressions. Plants can survive a limiting nitrogen supply by undergoing adaptive responses, including induction of anthocyanin production. However, the detailed mechanism is still unclear. In this study, we found that this process was impaired and enhanced, respectively, by exogenous GA3 (an active form of GAs) and paclobutrazol (PAC, a specific GA biosynthesis inhibitor) in Arabidopsis seedlings. Consistently, the nitrogen deficiency-induced transcript levels of several key genes involved in anthocyanin biosynthesis, including F3'H, DFR, LDOX, and UF3GT, were decreased and enhanced by exogenous GA3 and PAC, respectively. Moreover, the nitrogen deficiency-induced anthocyanin accumulation and biosynthesis gene expressions were impaired in the loss-of-function mutant gai-t6/rga-t2/rgl1-1/rgl2-1/rgl3-1 (della) but enhanced in the GA-insensitive mutant gai, suggesting that DELLA proteins, known as repressors of GA signaling, are necessary for fully induction of nitrogen deficiency-driven anthocyanin biosynthesis. Using yeast two-hybrid (Y2H) assay, pull-down assay, and luciferase complementation assay, it was found that RGA, a DELLA of Arabidopsis, could strongly interact with PAP1, a known regulatory transcription factor positively involved in anthocyanin biosynthesis. Furthermore, transient expression assays indicated that RGA and GAI could enhance the transcriptional activities of PAP1 on its downstream genes, including F3'H and DFR. Taken together, this study suggests that DELLAs are necessary regulators for nitrogen deficiency-induced anthocyanin accumulation through interaction with PAP1 and enhancement of PAP1's transcriptional activity on its target genes. GA-DELLA-involved anthocyanin accumulation is important for plant adaptation to nitrogen deficiency.

    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

    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.

    The Colorado School of Mines (CSM) has taught its first-semester introductory physics course using a hybrid lecture/Studio Physics format for several years. Over the past year we have converted the second semester of our calculus-based introductory physics course (Physics II) to a Studio Physics format, starting from a traditional lecture-based format. In this paper, we document the early stages of this conversion in order to better understand which features succeed and which do not, and in order to develop a model for switching to Studio that keeps the time and resource investment manageable. We describe the recent history of the Physics II course and of Studio at Mines, discuss the PER-based improvements that we are implementing, 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), solicited student comments, failure rates, and exam scores.

    2016-05-01

    Speech-language pathologists have long used technology for the clinical measurement of the speaking voice, but present research shows that vocal pedagogues and voice students are becoming more accepting of technology in the studio. As a result, the equipment and technology used in singing voice studios by speech-language pathologists and vocal pedagogues are changing. Although guides exist regarding equipment and technology necessary for developing a voice laboratory and private voice studio, there are no data documenting the current implementation of these items and their perceived effectiveness. This study seeks to document current trends in equipment used in voice laboratories and studios. Two separate surveys were distributed to 60 vocologists and approximately 300 student singers representative of the general singing student population. The surveys contained questions about the inventory of items found in voice studios and perceived effectiveness of these items. Data were analyzed using descriptive analyses and statistical analyses when applicable. Twenty-six of 60 potential vocologists responded, and 66 student singers responded. The vocologists reported highly uniform inventories and ratings of studio items. There were wide-ranging differences between the inventories reported by the vocologist and student singer groups. Statistically significant differences between ratings of effectiveness of studio items were found for 11 of the 17 items. In all significant cases, vocologists rated usefulness to be higher than student singers. Although the order of rankings of vocologists and student singers was similar, a much higher percentage of vocologists report the items as being efficient and effective than students. The historically typical studio items, including the keyboard and mirror, were ranked as most effective by both vocologists and student singers. Copyright © 2016 The Voice Foundation.

    This article presents an innovative model for interprofessional community-oriented learning. The Engagement Studios model involves a partnership between community organizations and students as equal partners in conversations and activities aimed at addressing issues of common concern as they relate to the social determinants of health. Interprofessional teams of students from health and non-health disciplines work with community partners to identify priority community issues and explore potential solutions. The student teams work with a particular community organization, combining their unique disciplinary perspectives to develop a project proposal, which addresses the community issues that have been jointly identified. Approved proposals receive a small budget to implement the project. In this paper we present the Engagement Studios model and share lessons learned from a pilot of this educational initiative.

    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.

  2. Inferring Caravaggio's studio lighting and praxis in The calling of St. Matthew by computer graphics modeling

    2010-02-01

    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

    Although not yet truly 'comprehensive', modern mass spectrometry-based experiments can generate quantitative data for a meaningful fraction of the human proteome. Importantly for large-scale protein expression analysis, robust data pipelines are in place for identification of un-modified peptide sequences and aggregation of these data to protein-level quantification. However, interoperable software tools that enable scientists to computationally explore and document novel hypotheses for peptide sequence, modification status, or fragmentation behavior are not well-developed. Here, we introduce mzStudio, an open-source Python module built on our multiplierz project. This desktop application provides a highly-interactive graphical user interface (GUI) through which scientists can examine and annotate spectral features, re-search existing PSMs to test different modifications or new spectral matching algorithms, share results with colleagues, integrate other domain-specific software tools, and finally create publication-quality graphics. mzStudio leverages our common application programming interface (mzAPI) for access to native data files from multiple instrument platforms, including ion trap, quadrupole time-of-flight, Orbitrap, matrix-assisted laser desorption ionization, and triple quadrupole mass spectrometers and is compatible with several popular search engines including Mascot, Proteome Discoverer, X!Tandem, and Comet. The mzStudio toolkit enables researchers to create a digital provenance of data analytics and other evidence that support specific peptide sequence assignments.

    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.

    A technical principle about construction of virtual studio has been proposed where orientation tracker and telemeter has been used for improving conventional BETACAM pickup camera and connecting with the software module of the host. A model of virtual camera named Camera & Post-camera Coupling Pair has been put forward, which is different from the common model in computer graphics and has been bound to real BETACAM pickup camera for shooting. The formula has been educed to compute the foreground frame buffer image and the background frame buffer image of the virtual scene whose boundary is based on the depth information of target point of the real BETACAM pickup camera's projective ray. The effect of real-time consistency has been achieved between the video image sequences of the master of ceremonies or players and the CG video image sequences for the virtual scene in spatial position, perspective relationship and image object masking. The experimental result has shown that the technological scheme of construction of virtual studio submitted in this paper is feasible and more applicative and more effective than the existing technology to establish a virtual studio based on color-key and image synthesis with background using non-linear video editing technique.

    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.

    Plant development requires coordination among complex signaling networks to enhance plant’s adaptation to changing environments. The transcription regulators DELLAs, originally identified as repressors of phytohormone gibberellin (GA) signaling, play a central role in integrating multiple signaling activities via direct protein interactions with key transcription factors. Here, we showed that DELLA was mono-O-fucosylated by a novel O-fucosyltransferase SPINDLY (SPY) in Arabidopsis thaliana. O-fucosylation activates DELLA by promoting its interaction with key regulators in brassinosteroid (BR)- and light-signaling pathways, including BRASSINAZOLE-RESISTANT1 (BZR1), PHYTOCHROME-INTERACTING-FACTOR3 (PIF3), and PIF4. Consistently, spy mutants displayed elevated responses to GA and BR, and increased expression of common target genes of DELLAs, BZR1 and PIFs. Our study revealed that SPY-dependent protein O-fucosylation plays a key role in regulating plant development. This finding has broader importance as SPY orthologs are conserved from prokaryotes to eukaryotes, suggesting that intracellular O-fucosylation may regulate a wide range of biological processes in diverse organisms.

    Maintenance of the inward transport of potassium (K) by roots is a critical step to ensure K-nutrition for all plant tissues. When plants are grown at low external K concentrations a strong enhancement of the activity of the AtHAK5 transporter takes place. In a recent work, we observed that the gai-1 mutant of Arabidopsis thaliana, which bears an altered function version of a DELLA regulatory protein, displays reduced accumulation of AtHAK5 transcripts and reduced uptake of Rubidium, an analog for K. In this Addendum we discuss some hypotheses and uncertainties regarding how DELLAs could contribute to the control of K uptake under those conditions. We advance the idea that, following K-restriction, there is a zone and tissue specific regulation of DELLAs by gibberellins through a pathway that likely involves ethylene. According to this model in the epidermis of non-apical zones, DELLAs repress transcription factors that promote AtHAK5 accumulation.

  12. 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 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.

    This case study explores the influence of the healthcare design studio experience on students' short-term professional goals as measured through rates of healthcare-related certification and internship/employment. The value and relevance of interior design is evident in the healthcare design sector. However, interior design students may not perceive this value if it is not communicated through their design education. Students' experience in the design studio plays a crucial role in determining career choices, and students may be more committed to career goals when there is clear connection between major coursework and professional practice. The authors compared healthcare-related certification and internship/employment levels between two student cohorts in a capstone undergraduate interior design healthcare design studio course. The first cohort was led by the existing curriculum. The second cohort was led by the revised curriculum that specifically aimed at encouraging students to commit to healthcare-related design practice. When measured at 3 months from graduation, the second cohort, led by the revised curriculum, saw a 30% increase in Evidence-based Design Accreditation and Certification exam pass rates and a 40% increase in healthcare-related internship/employment. The challenge of interior design education is to instill in emerging professionals not only professional competence but also those professional attitudes that will make them better prepared to design spaces that improve quality of life, particularly in healthcare environments. The results exceeded the project goals, and so this could be considered a promising practice for courses focused on healthcare design education.

    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.

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.

    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.

    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.

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 Mass Spec Studio package was designed to support the extraction of hydrogen-deuterium exchange and covalent labeling data for a range of mass spectrometry (MS)-based workflows, to integrate with restraint-driven protein modeling activities. In this report, we present an extension of the underlying Studio framework and provide a plug-in for crosslink (XL) detection. To accommodate flexibility in XL methods and applications, while maintaining efficient data processing, the plug-in employs a peptide library reduction strategy via a presearch of the tandem-MS data. We demonstrate that prescoring linear unmodified peptide tags using a probabilistic approach substantially reduces search space by requiring both crosslinked peptides to generate sparse data attributable to their linear forms. The method demonstrates highly sensitive crosslink peptide identification with a low false positive rate. Integration with a Haddock plug-in provides a resource that can combine multiple sources of data for protein modeling activities. We generated a structural model of porcine transferrin bound to TbpB, a membrane-bound receptor essential for iron acquisition in Actinobacillus pleuropneumoniae. Using mutational data and crosslinking restraints, we confirm the mechanism by which TbpB recognizes the iron-loaded form of transferrin, and note the requirement for disparate sources of restraint data for accurate model construction.

    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

    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.

    2015-01-01

    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

    Gli obbiettivi di questo studio sono stati: 1) lo studio della variabilità delle dimensioni cocleari in relazione all'età e al grado di ipoacusia; 2) calcolare la lunghezza dell'elettrodo dell'impianto cocleare richiesta per ottenere l'angolo ideale d'inserzione profonda di 270°. 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. La seguente equazione è stata adottata per calcolare la Lunghezza di un elettrodo rettilineo che segue la parete esterna della scala timpani necessaria per ottenere l'angolo ideale di inserzione profonda di 270° (LIC): [Formula: see text]. Secondo i nostri risultati alla nascita la coclea è completamente sviluppata e ha già raggiunto le dimensioni dell'adulto. Il Grado di ipoacusia non influenza la Lunghezza (L) e il Volume (V) della coclea, mentre può influenzare la sua altezza (H

    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.

    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.

    Background As presented in the introduction paper, three sets of differentially regulated genes were found after the analysis of the chicken infection data set from EADGENE. Different methods were used to interpret these results. Results GOTM, Pathway Studio and Ingenuity softwares were used to investigate the three lists of genes. The three softwares allowed the analysis of the data and highlighted different networks. However, only one set of genes, showing a differential expression between primary and secondary response gave significant biological interpretation. Conclusion Combining these databases that were developed independently on different annotation sources supplies a useful tool for a global biological interpretation of microarray data, even if they may contain some imperfections (e.g. gene not or not well annotated).

    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.

    The use of interactive engagement strategies to improve learning in introductory physics is not new, but have not been used as often for upper-division physics courses. We describe the development and implementation of a Studio Optics course for upper-division physics majors at Kansas State University. The course adapts a three-stage Karplus learning cycle and other elements to foster an environment that promotes learning through an integration of lecture, laboratories, and problem solving. Some of the instructional materials are described. We discuss the evaluation of the course using data collected from student interviews, a conceptual survey, an attitudinal survey, and the instructor's reflections. Overall, students responded positively to the new format and showed modest gains in learning. The instructor's experiences compared favorably with the traditional course that he had taught in the past.

    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.

    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

    OBJECTIVE--To examine the role of serum cholesterol in acute myocardial infarction in a population of patients with no history of coronary heart disease and to establish the nature of this association, the degree of risk, and the possible interaction between serum cholesterol and other major risk factors for acute myocardial infarction. DESIGN--Case-control study. SETTING--90 hospitals in northern, central, and southern Italy. PATIENTS--916 consecutive cases of newly diagnosed acute myocardial infarction and 1106 hospital controls admitted to hospital with acute conditions not related to known or suspected risk factors for coronary heart disease. DATA COLLECTION--Data were collected with a structured questionnaire and blood samples were taken by venepuncture as soon as possible after admission to hospital from cases and controls. Blood cholesterol concentrations were available for 614 cases and 792 controls. RESULTS--After adjustment by logistic regression for sex, age, education, geographical area, smoking status, body mass index, history of diabetes and hypertension, and family history of coronary heart disease the estimated relative risks of acute myocardial infarction for quintiles of serum cholesterol (from lowest to highest) were 2.3 (95% confidence interval (CI) 1.6 to 3.4), 3.1 (95% CI 2.1 to 4.6), 4.1 (95% CI 2.8 to 6.0), and 5.2 (95% CI 3.5 to 7.7). The estimated relative risk across selected covariates increased from the lowest to the highest quintile of serum cholesterol particularly for men, patients under 55 years of age, and smokers. When the possible interaction of known risk factors with serum cholesterol was examined, smoking habits, diabetes, and hypertension had approximately multiplicative effects on relative risk. CONCLUSIONS--This study indicates that serum cholesterol was an independent risk factor for acute myocardial infarction. This association was linear, with no threshold level. Moreover, there was a multiplicative effect between cholesterol and other major risk factors on the relative risk of acute myocardial infarction. PMID:8011413

    STUDY OBJECTIVE--The study aimed to investigate the relationship between years since stopping smoking and the risk of acute myocardial infarction. DESIGN--This was a hospital based, multicentre, case-control study conducted in Italy between September 1988 and June 1989 within the framework of the GISSI-2 clinical trial. SETTING--Over 80 coronary care units in various Italian regions participated. SUBJECTS--A total of 916 incident cases of acute myocardial infarction, below age 75 years, and with no history of ischaemic heart disease, and 1106 control subjects admitted to the same hospitals for acute, non-neoplastic, cardiovascular or cerebrovascular conditions that were not known or suspected to be related to cigarette smoking took part in the study. MAIN OUTCOME MEASURES AND RESULTS--Measures were relative risk (RR) estimates of acute myocardial infarction according to the time since stopping smoking and adjusted for identified potential confounding factors. Compared with never smokers, the multivariate RRs were 1.6 (95% confidence interval (CI) 0.8,3.2) for subjects who had given up smoking for one year; 1.4 (95% CI 0.9,2.1) for those who had stopped for two to five years; 1.2 (95% CI 0.7,2.1) for six to 10 years; and 1.1 (95% CI 0.8,1.8) for those who had not smoked for over 10 years. The estimated RR for current smokers was 2.9 (95% CI 2.2,3.9). The risks of quitters were higher for heavier smokers and those below age 50 years, while no difference emerged in relation to the duration of smoking, sex, and other risk factors for myocardial infarction. CONCLUSIONS--These results indicate that there is already a substantial drop in the risk of acute myocardial infarction one year after stopping. The risk in ex-smokers, however, seemed higher (although not significantly) than that of those who had never smoked, even more than 10 years after quitting. This could support the existence of at least two mechanisms linking cigarette smoking with acute myocardial infarction--one involving thrombogenesis or spasms that occurs over the short term, and another involving atherosclerosis that is a long term effect.

    Studies performed before the introduction of fibrinolysis showed that a low heart rate variability (HRV) is associated with higher mortality in post-myocardial infarction (MI) patients. We evaluated whether HRV adds information relevant to risk stratification in patients treated with fibrinolysis as well. From 24-hour ECG recordings obtained at discharge in patients treated with recombinant tissue-type plasminogen activator or streptokinase, we measured several time-domain indexes of HRV: standard deviation (SDNN), root-mean-square of successive differences (RMSSD), and number of RR interval increases > 50 ms ("NN50+"). The prognostic value of HRV for total and cardiovascular mortality was assessed. Of 567 patients with valid recordings, 52 (9.1%) died during the 1000 days of follow-up, 44 (7.8%) of cardiovascular causes. All indexes of low HRV were able to identify patients (16% to 18% of total population) with a higher total mortality (20.8% to 24.2% versus 6.0% to 6.8%, depending on index used). The independent predictive value of low HRV was confirmed by the adjusted analysis with the following relative risks: NN50+, 3.5 (95% CI, 1.9 to 6.7); SDNN, 3.0 (95% CI, 1.55 to 5.9); and RMSSD, 2.8 (95% CI, 1.5 to 5.3). Advanced age, previous MI, Killip class at entry, and use of digitalis were also independent predictors. Similar data were obtained for cardiovascular mortality. Time-domain indexes of HRV retain their independent prognostic significance even in post-MI patients of all ages treated with fibrinolysis.

    Clinical and epidemiological studies support the hypothesis that ischaemic cardiovascular diseases are consistently associated with psychological, social and behavioural factors. Nevertheless, the joint effect of clinical characteristics and psychological variables in determining the prognosis of acute myocardial infarction survivors has been seldom investigated. In the framework of the GISSI-2 trial, the impact of psychological factors on 6-month mortality and their interaction with clinical features was included as an ad hoc research project. Overall, 2449 patients were evaluated, 63 of whom died during the study period. All patients undertook a self-administered questionnaire (Cognitive Behavioural Assessment Hospital Form), investigating 16 psychological dimensions relative to three areas (state variables, vital exhaustion, trait variables). The impact of psychological variables on prognosis and their interaction with clinical variables were investigated by using a tree-growing technique (RECursive Partitioning and AMalgamation-RECPAM) applied to survival analysis. This statistical method allowed the identification of three separate classes, characterized by different prognoses: Class I (presence of vital exhaustion), Class II (concomitance of no vital exhaustion, depression and low levels of anxiety) and Class III (all other patients). After adjusting for the clinical variables, Class I was associated with an intermediate prognosis (hazard ratio [HR] = 2.2; 95% confidence intervals [CI], 1.2-4.0) and Class II to the worst (HR = 3.2; 95% CI = 1.6-6.2), as compared to Class III. High levels of neuroticism and extroversion were associated with a better prognosis. When clinical and psychological variables were simultaneously investigated by RECPAM, Type A behaviour was shown to be an important risk predictor among patients with better clinical conditions, i.e. those eligible for exercise test (HR = 2.6, 95% CI = 1.2-5.5). Finally, a striking difference in the impact of the most predictive clinical variables (exercise test ineligibility, late and early ventricular failure) was found among patients with and without vital exhaustion. This study shows that acute myocardial infarction survivors are heterogeneous with respect to 6-month mortality according to their psychological profile. More important, the impact of these variables appears comparable to that of very well known clinical risk predictors. The availability of a large study population, together with the use of innovative statistical techniques, allowed us to identify subgroups of patients for whom the joint action of clinical and psychological characteristics has been clearly documented. This suggests the need for incorporating psychological evaluation in the care of acute myocardial infarction patients.

    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.

    To examine the role of serum cholesterol in acute myocardial infarction in a population of patients with no history of coronary heart disease and to establish the nature of this association, the degree of risk, and the possible interaction between serum cholesterol and other major risk factors for acute myocardial infarction. Case-control study. 90 hospitals in northern, central, and southern Italy. 916 consecutive cases of newly diagnosed acute myocardial infarction and 1106 hospital controls admitted to hospital with acute conditions not related to known or suspected risk factors for coronary heart disease. Data were collected with a structured questionnaire and blood samples were taken by venepuncture as soon as possible after admission to hospital from cases and controls. Blood cholesterol concentrations were available for 614 cases and 792 controls. After adjustment by logistic regression for sex, age, education, geographical area, smoking status, body mass index, history of diabetes and hypertension, and family history of coronary heart disease the estimated relative risks of acute myocardial infarction for quintiles of serum cholesterol (from lowest to highest) were 2.3 (95% confidence interval (CI) 1.6 to 3.4), 3.1 (95% CI 2.1 to 4.6), 4.1 (95% CI 2.8 to 6.0), and 5.2 (95% CI 3.5 to 7.7). The estimated relative risk across selected covariates increased from the lowest to the highest quintile of serum cholesterol particularly for men, patients under 55 years of age, and smokers. When the possible interaction of known risk factors with serum cholesterol was examined, smoking habits, diabetes, and hypertension had approximately multiplicative effects on relative risk. This study indicates that serum cholesterol was an independent risk factor for acute myocardial infarction. This association was linear, with no threshold level. Moreover, there was a multiplicative effect between cholesterol and other major risk factors on the relative risk of acute myocardial infarction.

    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.

    To make a further quantitative assessment of the relationship between cigarette smoking and the risk of myocardial infarction, a multicentric case-control study was conducted in Italy between September 1988 and June 1989 within the framework of the GISSI-2 trial. 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 proportions of nonfatal acute myocardial infarctions (AMI) in Italy attributable to cigarette smoking, body mass, serum cholesterol level, hypertension, diabetes, and family history of AMI (attributable risks, AR) were estimated using data from a case-control study on 614 incident cases of AMI before age 75 with no history of ischemic heart disease and 792 control subjects admitted to the same hospitals where cases were identified for acute, nonneoplastic, cardio- or cerebrovascular conditions not known or suspected to be related to cigarette smoking. The study was conducted between September 1988 and June 1989 within the framework of the GISSI-2 clinical trial. We assumed a multiplicative model and thus the risk attributable to several factors combined is not the sum of those attributable to the single factors. Overall the AR of smoking was 49%, and for cholesterol, body mass, family history of AMI, hypertension, and diabetes the AR were 49, 16, 14, 13, and 6%, respectively. Together these factors explained 85% of AMI cases. Though differences emerged for each single factor, the proportion of AMI explained by the six factors together was approximately the same for both sexes, while these factors accounted for 97% of AMI cases before age 50 (and smoking alone for 70%) and for 80% after age 50. This study confirms that interventions on well-defined risk factors could, in principle, lead to the avoidance of the great majority of myocardial infarctions in this population (i.e., about 80% before age 75 and about 95% before age 50).

    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.

    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 study aimed to investigate the relationship between years since stopping smoking and the risk of acute myocardial infarction. This was a hospital based, multicentre, case-control study conducted in Italy between September 1988 and June 1989 within the framework of the GISSI-2 clinical trial. Over 80 coronary care units in various Italian regions participated. A total of 916 incident cases of acute myocardial infarction, below age 75 years, and with no history of ischaemic heart disease, and 1106 control subjects admitted to the same hospitals for acute, non-neoplastic, cardiovascular or cerebrovascular conditions that were not known or suspected to be related to cigarette smoking took part in the study. Measures were relative risk (RR) estimates of acute myocardial infarction according to the time since stopping smoking and adjusted for identified potential confounding factors. Compared with never smokers, the multivariate RRs were 1.6 (95% confidence interval (CI) 0.8,3.2) for subjects who had given up smoking for one year; 1.4 (95% CI 0.9,2.1) for those who had stopped for two to five years; 1.2 (95% CI 0.7,2.1) for six to 10 years; and 1.1 (95% CI 0.8,1.8) for those who had not smoked for over 10 years. The estimated RR for current smokers was 2.9 (95% CI 2.2,3.9). The risks of quitters were higher for heavier smokers and those below age 50 years, while no difference emerged in relation to the duration of smoking, sex, and other risk factors for myocardial infarction. These results indicate that there is already a substantial drop in the risk of acute myocardial infarction one year after stopping. The risk in ex-smokers, however, seemed higher (although not significantly) than that of those who had never smoked, even more than 10 years after quitting. This could support the existence of at least two mechanisms linking cigarette smoking with acute myocardial infarction--one involving thrombogenesis or spasms that occurs over the short term, and another involving atherosclerosis that is a long term effect.

    The relationship between expression of a negative regulator of GA signal transduction (RGL2) belonging to the DELLA gene family and repression of Arabidopsis seed germination has been studied (Lee S, Cheng H, King KE, Wang W, He Y, Hussain A, Lo J, Harberd NP, Peng J [2002] Genes and Development 16: 646-658). There is one DELLA gene (LeGAI) present in tomato (Lycopersicon esculentum Mill.), which is expressed in both vegetative and reproductive tissues. During germination of wild-type tomato seed, there was no decline in the expression of LeGAI in either the embryo or the endosperm. Rather, LeGAI transcripts increased in these tissues following imbibition and remained high during and following germination. A similar increase in LeGAI transcripts occurred in the endosperm and embryo of GA-treated gib-1 mutant seed during and following germination. Likewise in soybean (Glycine max) seed, there was no decline in the expression of two DELLA genes in the radicle before or after germination. Upon reexamination of RGL2 in Arabidopsis seeds, a decline in its expression was noted but only after radicle emergence, i.e. after germination had been completed. Taken together, these data are consistent with GA-induced down-regulation of DELLA genes not being a prerequisite for germination of tomato, soybean, and Arabidopsis seeds.

    Background Plant viral infections disturb defense regulatory networks during tissue invasion. Emerging evidence demonstrates that a significant proportion of these alterations are mediated by hormone imbalances. Although the DELLA proteins have been reported to be central players in hormone cross-talk, their role in the modulation of hormone signaling during virus infections remains unknown. Results This work revealed that TMV-Cg coat protein (CgCP) suppresses the salicylic acid (SA) signaling pathway without altering defense hormone SA or jasmonic acid (JA) levels in Arabidopsis thaliana. Furthermore, it was observed that the expression of CgCP reduces plant growth and delays the timing of floral transition. Quantitative RT-qPCR analysis of DELLA target genes showed that CgCP alters relative expression of several target genes, indicating that the DELLA proteins mediate transcriptional changes produced by CgCP expression. Analyses by fluorescence confocal microscopy showed that CgCP stabilizes DELLA proteins accumulation in the presence of gibberellic acid (GA) and that the DELLA proteins are also stabilized during TMV-Cg virus infections. Moreover, DELLA proteins negatively modulated defense transcript profiles during TMV-Cg infection. As a result, TMV-Cg accumulation was significantly reduced in the quadruple-DELLA mutant Arabidopsis plants compared to wild type plants. Conclusions Taken together, these results demonstrate that CgCP negatively regulates the salicylic acid-mediated defense pathway by stabilizing the DELLA proteins during Arabidopsis thaliana viral infection, suggesting that CgCP alters the stability of DELLAs as a mechanism of negative modulation of antiviral defense responses.

    Identification and characterization of a semi-dwarfing gene ds-3 encoding a mutant DELLA protein regulating plant height through gibberellin signaling pathway. Lodging is one of the most important factors causing severe yield loss in oilseed rape. Utilization of semi-dwarf varieties has been proved the most effective way to increase lodging resistance and yield in many crops. To develop semi-dwarf germplasm in oilseed rape, we identified a semi-dwarf mutant ds-3 which showed a reduced response to phytohormones gibberellins (GAs). Genetic analysis indicated the dwarfism was controlled by a single semi-dominant gene, ds-3. The DS-3 gene was mapped to a genomic region on chromosome C07, which is syntenic to the region of a previously identified semi-dwarf gene ds-1 (BnaA06.RGA). In this region, DS-3 (BnaC07.RGA) gene was identified to encode a DELLA protein that functions as a repressor in GA signaling pathway. A substitution of proline to leucine was identified in ds-3 in the conserved VHYNP motif, which is essential for GA-dependent interaction between gibberellin receptor GID1 and DELLA proteins. Segregation analysis in the F2 population derived from the cross between ds-1 and ds-3 demonstrated that BnaA06.RGA displayed a stronger effect on plant height than BnaC07.RGA, indicating that different RGA genes may play different roles in stem elongation. In addition to BnaA06.RGA and BnaC07.RGA, two more RGA genes (BnaA09.RGA and BnaC09.RGA) were identified in the Brassica napus (B. napus) genome. Reverse-transcription polymerase chain reaction (RT-PCR) and yeast two-hybrid (Y2H) assays suggest that both BnaA09.RGA and BnaC09.RGA are transcribed in leaves and stems and can mediate GA signaling in vivo. These genes represent potential targets for screening ideal semi-dwarfing alleles for oilseed rape breeding.

    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.

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.

    The objectives of this ethnographic study were to understand the effect of an integrated arts studio on the lives of the participants including the impact of social isolation, stigma and discrimination, and to study the importance of consumer perspective in the design and implementation of the program. Methods included the use of semi-structured in-depth interviews, participant-observation, journal keeping, and document review with twenty individuals. Ten participants self identified as having mental illnesses, and their diagnoses were varied in severity and description; the other ten participants reported no mental illnesses. A key finding of the study was that art making provided participants the opportunity to build new identities and roles, and that through engagement in mutually meaningful activity, in this case making art, a community of artists developed. Art was also seen as a bridge creating access to the larger community. These findings add further evidence for the power of art making as a practical strategy to affect the health of individuals living with psychiatric disabilities as well as the communities in which they reside.

    The study of temperature and air flow for natural ventilation system has been investigated numerically. A finite element model for studio apartment was developed with the aim of achieving detail energy allocation in the real buildings during the transient process in the walls and internal air. A tool of computational fluid dynamics (CFD) is employed to assist the process. In the tropical regions most of the energy is consumed by the heating, cooling and ventilation appliances. Therefore, the optimize ventilation system will be a suitable and valid option for the saving of energy from the household sector to increase cooling performance and ensuring thermal comfort as well. A mathematical exploration is carried out on full scale dwelling and small scale model and indication is given on the relevance of such a comparison. Calculations are carried out with household heat sources for calm and windy period, but without any human. As expected, for windy periods, the wind is the main driving force behind the internal air flow. However, in calm periods for unsteady flow the internal airflow looks like more complexes through observation.

    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.

    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.

    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 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.

    Artists Bob and Louise McCall in their Paradise Valley, Arizona studio, in front of "Celebrating One Hundred Years of Powered Flight 1903-2003." The mural was created to celebrate the achievements of Wilbur and Orville Wright and to commemorate a century of powered flight. Many of the epic flights represented in the painting took place in the skies over NASA Dryden Flight Research Center. An equally important goal of this celebration is to encourage the values that have characterized 100 years of aviation history: ingenuity, inventiveness, persistence, creativity and courage. These values hold true not just for pioneers of flight, but also for all pioneers of invention and innovation, and they will remain an important part of America's future. "Celebrating One Hundred Years of Powered Flight, 1903-2003", documents many significant achievements in aeronautics and space flight from the dawn of powered flight to the present. Historic aircraft and spacecraft serve as the backdrop, highlighting six figures representing the human element that made these milestones possible. These figures stand, symbolically supported by the words of Wilbur Wright, "It is my belief that flight is possible…" The quote was taken from a letter written to his father on September 3rd, 1900, announcing Wilbur's intention to make "some experiments with a flying machine" at Kitty Hawk, North Carolina. "This year, Bob is helping us commemorate the Centennial of Flight with a beautiful mural slated for placement in our Dryden Flight Research Center that documents the history of flight from the Wright Flyer to the International Space Station. We should all take note, I think, that in the grand scheme of things, one hundred years is a very short period of time. In that blink of an eye we've gone from Kitty Hawk to Tranquility Base and now look forward to our rovers traversing the surface of Mars.

    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

    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.

    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.

    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.

    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.

  8. Chromosomenindividualität or Entmischung? The debate between Paolo Della Valle and Edmund B. Wilson.

    2015-01-01

    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.

    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%).

    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.

    Тhe sensitivity to cadmium (Cd) stress of two near-isogenic wheat lines with differences at the Rht-B1 locus, Rht-B1a (tall wild type, encoding DELLA proteins) and Rht-B1c (dwarf mutant, encoding modified DELLA proteins), was investigated. The effects of 100 μM CdCl2 on plant growth, pigment content and functional activity of the photosynthetic apparatus of wheat seedlings grown on a nutrient solution were evaluated through a combination of PAM chlorophyll fluorescence, oxygen evolution, oxidation-reduction kinetics of P700 and 77 K fluorescence. The results showed that the wheat mutant (Rht-B1c) was more tolerant to Cd stress compared to the wild type (Rht-B1a), as evidenced by the lower reductions in plant growth and pigment content, lower inhibition of photosystem I (PSI) and photosystem II (PSII) photochemistry and of the oxygen evolution measured with Clark-type and Joliot-type electrodes. Furthermore, the enhanced Cd tolerance was accompanied by increased Cd accumulation within mutant plant tissues. The molecular mechanisms through which the Rht-B1c mutation improves plant tolerance to Cd stress involve structural alterations in the mutant photosynthetic membranes leading to better protection of the Mn cluster of oxygen-evolving complex and increased capacity for PSI cyclic electron transport, protecting photochemical activity of the photosynthetic apparatus under stress. This study suggests a role for the Rht-B1c-encoded DELLA proteins in protective mechanisms and tolerance of the photosynthetic apparatus in wheat plants exposed to heavy metals stress.

    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.

    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.

    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.

    RIASSUNTO. Scopo. È noto come l'anoressia nervosa (AN) e il disturbo dello spetto autistico (ASD) condividano alcuni tratti, come la rigidità mentale e l'attenzione per i dettagli, che potrebbero essere diffusi a livello familiare. Questo studio ha lo scopo di confrontare la distribuzione di tratti autistici in genitori con figlie affette da disturbo alimentare ED (anoressia - AN o bulimia nervosa - BN) con genitori appartenenti a un gruppo di controllo. Metodi. Sono stati coinvolti 40 genitori con figlie affette da disturbo alimentare (60% con anoressia, 40% con bulimia nervosa) e 33 genitori di controllo. Tutti i genitori hanno compilato questionari specifici riguardanti il quoziente di spettro autistico (AQ) e le stime cognitive (CET). Inoltre, sono stati somministrati EAT-26 e SCL-90-R al fine di escludere la presenza di disturbi psichiatrici o alimentari nel gruppo sperimentale. Risultati. Le analisi su AQ mostrano una differenza tra i due gruppi per un tratto autistico specifico, evidenziando una riduzione significativa dell'attenzione per i dettagli nel gruppo sperimentale (ED), in particolare nei genitori di figlie affette da AN. Discussione. Questi dati suggeriscono una preferenza per un'elaborazione globale delle informazioni nei genitori AN in contrasto a quanto trovato in pazienti con AN. La presenza di aspetti depressivi, ansiosi e di disturbi alimentari è stata esclusa nei genitori nel gruppo sperimentale tramite SCL-90-R e EAT-26. Infine, la capacità di prendere decisioni, misurata dal CET, è stata esclusa dalle nostre analisi. Conclusione. Nei genitori con figlie affette da AN emerge una peculiare preferenza per un'elaborazione cognitiva globale, suggerendo il ruolo dell'attenzione per i dettagli come nuovo fattore da considerare nelle valutazione cliniche di pazienti con AN e nei loro familiari. Considerando i limiti dello studio, ulteriori approfondimenti in merito sono necessari.

    2014-12-01

    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 hermaphroditic Arabidopsis, the phytohormone gibberellin (GA) stimulates stamen development by opposing the DELLA repression of B and C classes of floral homeotic genes. GA can promote male flower formation in cucumber (Cucumis sativus L.), a typical monoecious vegetable with unisexual flowers, and the molecular mechanism remains unknown. Here we characterized a DELLA homolog CsGAIP in cucumber, and we found that CsGAIP is highly expressed in stem and male flower buds. In situ hybridization showed that CsGAIP is greatly enriched in the stamen primordia, especially during the hermaphrodite stage of flower development. Further, CsGAIP protein is located in nucleus. CsGAIP can partially rescue the plant height, stamen development and fertility phenotypes of Arabidopsis rga-24/gai-t6 mutant, and ectopic expression of CsGAIP in wide-type Arabidopsis results in reduced number of stamens and decreased transcription of B class floral homeotic genes APETALA3 (AP3) and PISTILLATA (PI). Our data suggest that monoecious CsGAIP may inhibit staminate development through transcriptional repression of B class floral homeotic genes in Arabidopsis.

    Caciofiore della Sibilla is a speciality ewes' milk cheese traditionally manufactured in a foothill area of the Marche region (Central Italy) with a crude extract of fresh young leaves of Carlina acanthifolia All. subsp. acanthifolia as a coagulating agent. The fungal dynamics and diversity of this speciality cheese were investigated throughout the manufacturing and 20-day ripening process, using a combined PCR-DGGE approach. The fungal biota of a control ewes' milk cheese, manufactured with the same batch of milk coagulated with a commercial animal rennet, was also monitored by PCR-DGGE, in order to investigate the contribution of the peculiar vegetable coagulant to the fungal diversity and dynamics of the cheese. Based on the overall results collected, the raw milk and the dairy environment represented the main sources of fungal contamination, with a marginal or null contribution of thistle rennet to the fungal diversity and dynamics of Caciofiore della Sibilla cheese.

    Rht-B1c, allelic to the DELLA protein-encoding gene Rht-B1a, is a natural mutation documented in common wheat (Triticum aestivum). It confers variation to a number of traits related to cell and plant morphology, seed dormancy, and photosynthesis. The present study was conducted to examine the sequence variations of Rht-B1c and their functional impacts. The results showed that Rht-B1c was partially dominant or co-dominant for plant height, and exhibited an increased dwarfing effect. At the sequence level, Rht-B1c differed from Rht-B1a by one 2kb Veju retrotransposon insertion, three coding region single nucleotide polymorphisms (SNPs), one 197bp insertion, and four SNPs in the 1kb upstream sequence. Haplotype investigations, association analyses, transient expression assays, and expression profiling showed that the Veju insertion was primarily responsible for the extreme dwarfing effect. It was found that the Veju insertion changed processing of the Rht-B1c transcripts and resulted in DELLA motif primary structure disruption. Expression assays showed that Rht-B1c caused reduction of total Rht-1 transcript levels, and up-regulation of GATA-like transcription factors and genes positively regulated by these factors, suggesting that one way in which Rht-1 proteins affect plant growth and development is through GATA-like transcription factor regulation.

    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.

    Drought is responsible for considerable yield losses in agriculture due to its detrimental effects on growth. Drought responses have been extensively studied, but mostly on the level of complete plants or mature tissues. However, stress responses were shown to be highly tissue and developmental stage specific, and dividing tissues have developed unique mechanisms to respond to stress. Previously, we studied the effects of osmotic stress on dividing leaf cells in Arabidopsis (Arabidopsis thaliana) and found that stress causes early mitotic exit, in which cells end their mitotic division and start endoreduplication earlier. In this study, we analyzed this phenomenon in more detail. Osmotic stress induces changes in gibberellin metabolism, resulting in the stabilization of DELLAs, which are responsible for mitotic exit and earlier onset of endoreduplication. Consequently, this response is absent in mutants with altered gibberellin levels or DELLA activity. Mitotic exit and onset of endoreduplication do not correlate with an up-regulation of known cell cycle inhibitors but are the result of reduced levels of DP-E2F-LIKE1/E2Fe and UV-B-INSENSITIVE4, both inhibitors of the developmental transition from mitosis to endoreduplication by modulating anaphase-promoting complex/cyclosome activity, which are down-regulated rapidly after DELLA stabilization. This work fits into an emerging view of DELLAs as regulators of cell division by regulating the transition to endoreduplication and differentiation.

    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.

    Drought is responsible for considerable yield losses in agriculture due to its detrimental effects on growth. Drought responses have been extensively studied, but mostly on the level of complete plants or mature tissues. However, stress responses were shown to be highly tissue and developmental stage specific, and dividing tissues have developed unique mechanisms to respond to stress. Previously, we studied the effects of osmotic stress on dividing leaf cells in Arabidopsis (Arabidopsis thaliana) and found that stress causes early mitotic exit, in which cells end their mitotic division and start endoreduplication earlier. In this study, we analyzed this phenomenon in more detail. Osmotic stress induces changes in gibberellin metabolism, resulting in the stabilization of DELLAs, which are responsible for mitotic exit and earlier onset of endoreduplication. Consequently, this response is absent in mutants with altered gibberellin levels or DELLA activity. Mitotic exit and onset of endoreduplication do not correlate with an up-regulation of known cell cycle inhibitors but are the result of reduced levels of DP-E2F-LIKE1/E2Fe and UV-B-INSENSITIVE4, both inhibitors of the developmental transition from mitosis to endoreduplication by modulating anaphase-promoting complex/cyclosome activity, which are down-regulated rapidly after DELLA stabilization. This work fits into an emerging view of DELLAs as regulators of cell division by regulating the transition to endoreduplication and differentiation. PMID:22535421

    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

    Multiple input multiple output (MIMO) measurements were performed with a chirp sounder with a switched antenna array at the transmitter and eight parallel receiver channels with 96-MHz bandwidth at 2.25 GHz in TV studios and 240-MHz bandwidth at 2.38 GHz inside buildings. MIMO capacity was estimated from the data with linear and circular arrays with array sizes 2 by 2, 4 by 4, and 6 by 8. Mean capacity estimates for 30-dB signal-to-noise ratio for both line of sight and obstructed line of sight were on the order of 11-31 b/s/Hz for the 2 by 2 to 4 by 4 antenna configurations and for the 6 by 8 directional antenna measurements a median capacity of 50 b/s/Hz. This is an increase of 20 b/s/Hz from the 4 by 4 omnidirectional antenna array indicating diversity gain as well as an increase due to the number of antennas.

    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.

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

    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.

    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.

    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.

    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

    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.

Many of the epic flights represented in the painting took place in the skies over NASA Dryden Flight Research Center. An equally important goal of this celebration will be to encourage the values that have characterized 100 years of aviation history: ingenuity, inventiveness, persistence, creativity and courage. These values hold true not just for pioneers of flight, but also for all pioneers of invention and innovation, and they will remain an important part of America's future. "Celebrating One Hundred Years of Powered Flight, 1903-2003", documents many significant achievements in aeronautics and space flight from the dawn of powered flight to the present. Historic aircraft and spacecraft serve as the backdrop, highlighting six figures representing the human element that made these milestones possible. These figures stand, symbolically supported by the words of Wilbur Wright, "It is my belief that flight is possible…" The quote was taken from a letter written to his father on September 3rd, 1900, announcing Wilbur's intention to make "some experiments with a flying machine" at Kitty Hawk, North Carolina.

    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.

    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

    To evaluate the impact of the CCSEP on care home staff in two care settings for older people in one nursing home and one residential home. Care homes provide personal care and accommodation for older people. The English Dementia Strategy aims to improve the quality of service provision for people with dementia. This includes specific mention of improving the quality of life in care homes and as such includes objectives related to developing the workforce knowledge and skills. The Ladder to the Moon Culture Change Studio Engagement Programme (CCSEP) is a staff training approach based on the Positive Psychology framework that uses theatre- and film-based activities. This study used a wait-list controlled design. However, the data analysis plan was amended to reflect difficulties in data collection, and a quasi-experimental case study approach was consequently utilised. Outcome measures for staff attitudes and beliefs were as follows: Sense of Competence in Dementia Care Staff; Approaches to Dementia Questionnaire; Job Satisfaction Index; Brief Learning Transfer System Inventory; and Scale of Positive and Negative Experience. The Quality of Interaction Schedule (QUIS) was used to observe changes in staff-resident interaction. Fifty staff in two care homes completed the questionnaires and forty-one undertook formal CCSEP training. In Home A (nursing home), there was no significant change in any of the measures. In Home B (residential home), the QUIS showed an increase in positive interactions post intervention; a significant increase in the Building Relationship subscale of Sense of Competence; and a significant increase in staff sense of hopefulness towards people with dementia. The Brief Learning Transfer System Inventory showed a significant decrease post-intervention. The intervention did not significantly affect the happiness or job satisfaction of care home staff. The results of this study provide tentative evidence about the efficacy of this staff training

    DELLA proteins, consisting of GA INSENSITIVE, REPRESSOR OF GA1-3, RGA-LIKE1 (RGL1), RGL2, and RGL3, are central repressors of gibberellin (GA) responses, but their molecular functions are not fully understood. We isolated four DELLA-interacting RING domain proteins, previously designated as BOTRYTIS SUSCEPTIBLE1 INTERACTOR (BOI), BOI-RELATED GENE1 (BRG1), BRG2, and BRG3 (collectively referred to as BOIs). Single mutants of each BOI gene failed to significantly alter GA responses, but the boi quadruple mutant (boiQ) showed a higher seed germination frequency in the presence of paclobutrazol, precocious juvenile-to-adult phase transition, and early flowering, all of which are consistent with enhanced GA signaling. By contrast, BOI overexpression lines displayed phenotypes consistent with reduced GA signaling. Analysis of a gai-1 boiQ pentuple mutant further indicated that the GAI protein requires BOIs to inhibit a subset of GA responses. At the molecular level, BOIs did not significantly alter the stability of a DELLA protein. Instead, BOI and DELLA proteins are targeted to the promoters of a subset of GA-responsive genes and repress their expression. Taken together, our results indicate that the DELLA and BOI proteins inhibit GA responses by interacting with each other, binding to the same promoters of GA-responsive genes, and repressing these genes.

    Not so long ago the occasional story would be told in the news that someone with a fascination for all things medical had spent months or even years masquerading as a doctor in a large and anonymous hospital. No doubt the absence of such stories today is due to heightened security and vigilance, partly as a result of the realization among hospital…

    The Tempio della Consolazione in Todi (16th cent.) has always been one of the most significant symbols of the Umbrian landscape. Since the first times after its completion (1606) the structure has exhibited evidences of instability, due to foundation subsiding and/or seismic activity. Structural and geotechnical countermeasures have been undertaken on the Tempio and its surroundings from the 17th century until recent times. Until now a truly satisfactory analysis of the overall deformation and attitude of the building has not been performed, since the existing surveys record the overhangs of the pillars, the crack pattern or the subsidence over limited time spans. Describing the attitude of the whole church is in fact a complex operation due to the architectural character of the building, consisting of four apses (three polygonal and one semicircular) covered with half domes, which surround the central area with the large dome. The present research aims to fill the gap of knowledge with a global study based on geomatic techniques for an accurate 3D reconstruction of geometry and attitude, integrated with a historical research on damage and interventions and a geotechnical analysis. The geomatic survey results from the integration of different techniques: GPS-GNSS for global georeferencing, laser scanning and digital photogrammetry for an accurate 3D reconstruction, high precision total station and geometric leveling for a direct survey of deformations and cracks, and for the alignment of the laser scans. The above analysis allowed to assess the dynamics of the cracks occurred in the last 25 years by a comparison with a previous survey. From the photographic colour associated to the point cloud was also possible to map the damp patches showing on the domes intrados, mapping their evolution over the last years.

    Non-bonded interaction forces play crucial roles in molecular recognition and binding in biological systems. However, it is difficult for traditional methods to automatically calculate and batch the non-bonded energy at the residue level. In recent years, many studies have focused on non-bonded interactions and developed tools to calculate and analyze such interactions. In this study, we present a highly automated approach for the calculation of non-bonded energy. Our strategy invoked protocols relevant to non-bonded interactions within Discovery Studio 2.0 (DS2.0, Accelrys Inc.) bottom module using Perl script, and determined the direct command line operation of calculating non-bonded interaction energy batches without accessing the graphical interface of DS. This approach extended the DS2.0 module and was applied to a recent study of complex structure analysis.

    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.

    The aim of this study was to evaluate the prognostic significance of the pressure-rate product (PRP) obtained during exercise stress testing and of its change from rest to maximal exercise (dPRP) in a population of survivors of acute myocardial infarction treated with thrombolytic agents. Survivors of acute myocardial infarction (n = 6251) from the GISSI-2 database, who underwent a maximal symptom-limited exercise test with either bicycle ergometer or treadmill, were followed up for 6 months. PRP and dPRP values were dichotomized (21,700, 11,600, respectively) and analyzed in a multivariate Cox model individually and simultaneously with other ergometric variables. Six-month mortality rate was 0.8% in the high PRP group and 2.0% in the low PRP group. Low PRP was an independent predictor of 6-month mortality rate (relative risk [RR] 1.97, 95% confidence interval [CI] 1.24 to 3.13). Patients with low dPRP had mortality rates higher than patients with high dPRP (2.1% vs 0.8%). At the multivariate analysis, low dPRP showed negative predictive value (RR 1.97, 95% CI 1.23 to 3.16). A further multivariate analysis was performed with PRP and dPRP, also adjusting for low work capacity, abnormal systolic blood pressure response to exercise, and symptomatic-induced ischemia. The results showed that low work capacity, low PRP, and symptomatic exercise-induced ischemia were still significantly associated with higher 6-month mortality rate (P =.04,.02, and.05; RR = 1.68, 1.71, and 1.78 respectively). PRP is a predictive index to assess prognosis in survivors of acute myocardial infarction treated with thrombolytic agents able to perform an exercise test after acute myocardial infarction, but its usefulness appears to be limited, considering that these patients were at low risk.

    The rice (Oryza sativa) DELLA protein SLR1 acts as a repressor of gibberellin (GA) signaling. GA perception by GID1 causes SLR1 protein degradation involving the F-box protein GID2; this triggers GA-associated responses such as shoot elongation and seed germination. In GA-insensitive and GA biosynthesis mutants, SLENDER RICE1 (SLR1) accumulates to high levels, and the severity of dwarfism is usually correlated with the level of SLR1 accumulation. An exception is the GA-insensitive F-box mutant gid2, which shows milder dwarfism than mutants such as gid1 and cps even though it accumulates higher levels of SLR1. The level of SLR1 protein in gid2 was decreased by loss of GID1 function or treatment with a GA biosynthesis inhibitor, and dwarfism was enhanced. Conversely, overproduction of GID1 or treatment with GA(3) increased the SLR1 level in gid2 and reduced dwarfism. These results indicate that derepression of SLR1 repressive activity can be accomplished by GA and GID1 alone and does not require F-box (GID2) function. Evidence for GA signaling without GID2 was also provided by the expression behavior of GA-regulated genes such as GA-20oxidase1, GID1, and SLR1 in the gid2 mutant. Based on these observations, we propose a model for the release of GA suppression that does not require DELLA protein degradation.

    The Comunity Health Centre (CHC) primary care model is a team-based health care delivery model intended to provide comprehensive and continuous medical care to patients within a defined community. The CHC, Case della Salute in Italian, model was introduced in the Emilia-Romagna Region in 2010. We present updated data on the implementation on the CHC Case della Salute primary care model in the Emilia-Romagna Region. There are 67 operating CHCs in Emilia-Romagna (update March 2015); 26 small (39%), 24 medium (36%) and 17 large (25%). Since 2011 the number of operating CHCs has increased by 60%, reaching 55% of the target planned CHCs (n. = 122). There is, on average, one running CHC per 66.524 inhabitants. 16% of total general practitioners (GPs) and 8.4% of total family paediatricians working in Emilia-Romagna have their practice in CHCs. CHCs offer primary and specialist integrated care, prevention services, health education and social care. Although preliminary results suggest CHCs have fostered primary care's quality and efficiency, more research is needed to assess their impact on improving clinical, social and economic outcomes.

    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

    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.

  12. Lateral organisation in nineteenth-century studio photographs is influenced by the direction of writing: a comparison of Iranian and Spanish photographs.

    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.

    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.

    In the work is analysed a sequential control system of a machine for separating and grouping work pieces for processing. Whereas, the area of the considered problem is related with verification of operation of an actuator system of an electro-pneumatic control system equipped with a PLC controller. Wherein to verification is subjected the way of operation of actuators in view of logic relationships assumed in the control system. The actuators of the considered control system were three drives of linear motion (pneumatic cylinders). And the logical structure of the system of operation of the control system is based on the signals flow graph. The tested logical structure of operation of the electro-pneumatic control system was implemented in the Automation Studio software of B&R company. This software is used to create programs for the PLC controllers. Next, in the FluidSIM software was created the model of the actuator system of the control system of a machine. To verify the created program for the PLC controller, simulating the operation of the created model, it was utilized the approach of integration these two programs using the tool for data exchange in the form of the OPC server.

    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.

    Historical Building Information Modeling (H-BIM) has been widely documented in literature and is becoming more popular with government bodies, who are increasingly choosing to make its use mandatory in public procurements and contracts. Although the system seems to be one of the best approaches for managing data and driving the decision-making process, several difficulties arise due to the amount of effort required in the initial phases, when the data derived from a geometrical survey must be converted into parametric elements. Moreover, users must decide on a "level of geometrical simplification" a long time in advance, and this inevitably leads to a loss of geometrical data. From this perspective, our research describes a procedure to optimize the workflow of information for existing artefacts, in order to achieve a "lean" H-BIM. In this article, we will analyse two aspects: the first relates to the level of accuracy in a digital model created from the two different point clouds achieved from laser scanner and form images, while the second concerns the conversion of this information into parametric elements (Building Object Models- BOMs) that need to have specific characteristics. The case study we are presenting is the "Ponte Giorgini" ("Giorgini Bridge") in Castiglione della Pescaia (Grosseto - Italy).

    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.

    Eutrophication in the Palude della Rosa, in the Lagoon of Venice, results from agricultural runoff giving rise to a seasonal cycle of proliferation and subsequent decomposition of the green alga Ulva rigidaduring the summer months, with a dramatic fall in oxygen levels. A survey of the meiofauna at 42 stations in the Palude in December 1991 showed that there were two distinct associations of nematodes and total meiofauna (nematodes plus copepods), one associated with that part of the Palude where Ulvaattains a high biomass, and another where Ulvabiomass is low or absent. Species characteristic of the Ulvaregion include nematodes of the genus Diplolaimellaand copepods of the genus Tisbe, both of which are known from elsewhere to be associated with decaying plant material and implicated in the decomposition process. In the Ulvaregion both diversity (as evidenced from k-dominance curves) and species composition (using non-metric MDS) varied considerably from season to season, associated with the seasonal cycle of growth and decay of Ulva, but diversity and species composition were more stable seasonally in the non- Ulvaregion. For the copepods alone, differences between the Ulvaand non- Ulvaregions were not as evident and species composition in both regions changes seasonally in the same way, although diversity was only reduced markedly in the summer at the Ulvastations. We conclude that it is not only likely that the Ulvacycle controls seasonal changes in meiobenthic community composition, but in turn the meiobenthic community has some control over the Ulvacycle.

    In this paper we report a scheme of low-cost, small-size differential electrical converter to change analog trigger signals into digital trigger signals. This converter successfully resolves the incompatibility between the digital trigger mode of NI (National Instruments) data acquisition card PCI 5105 in Measurement Studio development environment for a demodulator and the requirement from instability of spectra of fiber Bragg grating (FBG) sensors. The instability is caused by intrinsic drifts of FFP-TF inside this high speed demodulator. The obtained results of frequency response about the converter have clearly demonstrated that this method is effective when the frequency of trigger signal is less than 3,000 Hz. This converter can satisfy the current requirements of demodulator based on FFP-TF, since mostly actual working scanning frequency of FFP-TF is less than 1,000 Hz. This method may be recommended to resolve similar problems for other NI customers who have developed their data acquisition system based on Measurement Studio.
