    Chronic inflammation plays a pivotal role in the development of renal disease. Circadian sleep-wake rhythm is disturbed in renal disease. Awareness of other disturbed rhythms, such as inflammation processes, can affect the treatment of patients with renal disease. Knowledge of possibly related circadian misalignment of the cytokines erythropoietin (EPO), Insulin Growth Factor-1 (IGF-1) and interleukins (IL) however is limited. We therefore performed an observational study. The objective of this study was to characterize levels of EPO, IGF-1 and inflammation markers IL-6 and TNF-α, related to renal function. The study population consisted of patients with various degrees of renal function, admitted to our hospital. During 24 hours, blood of 28 subjects with various degrees of renal function was collected every 2 hours. The patients were stable, not acutely ill and they were waiting for a procedure, such as elective surgery. Circadian parameters of EPO, IGF-1, IL-6 and TNF-α were measured in serum and were correlated with glomerular filtration rate (GFR) and Hb, using Pearson correlations. Although diurnal variations in EPO level were found in 15 out of 28 patients, the curves did not show a consistent phase. The presence of an EPO rhythm was not related to GFR. No diurnal rhythm could be detected for IGF-1, IL-6 and TNF-α. Mean levels of IGF-1 were correlated inversely to mean levels of EPO (p=0.03). When divided based on GFR and Hb subjects with GFR 10-30 ml/min and lower Hb had the highest IGF-1 levels (p=0.02). A relationship between Il-6, TNF-α and EPO or GFR was not found. The existence of a circadian (mis)alignment of EPO, IGF-1, IL-6 and TNF-α was not found. The association between high IGF-1 and low Hb suggests that EPO and IGF-1 have an alternating role, dependent on GFR, in stimulating erythropoiesis. These results could have consequences for the treatment of anemia.

    The misuse of microdoses of performance enhancing drugs like erythropoietin (EPO) constitutes a major challenge in doping analysis. When injected intravenously, the half-life of recombinant human EPO (rhEPO) like epoetin alfa, beta, and zeta is only a few hours and hence, the window for direct detection of rhEPO in urine is small. In order to investigate the detection window for rhEPO directly in blood and urine with a combined affinity chromatography and lateral flow immunoassay (EPO WGA MAIIA), we recruited nine healthy people who each received six intravenously injected microdoses (7.5 IU/kg) of NeoRecormon (epoetin beta) over a period of three weeks. Blood and urine samples were collected in the days following the injections and analyzed with EPO WGA MAIIA as well as the current validated methods for rhEPO; isoelectric focusing (IEF) and sarcosyl polyacrylamide gel electrophoresis (SAR-PAGE). For samples collected 18 h after a microdose, the sensitivity of the EPO WGA MAIIA assay was 100% in plasma and 87.5% in urine samples at the respective 98% specificity threshold levels. In comparison, the sensitivity in plasma and urine was 75% and 100%, respectively, with IEF, and 87.5% in plasma and 100% in urine when analyzed with SAR-PAGE. We conclude that EPO WGA MAIIA is a sensitive assay for the detection of rhEPO, with the potential of being a fast, supplemental screening assay for use in doping analysis.

    Full Text Available Job stress can be caused by organizational factors and non-organizational factors. In the organizational factor, the dimensions of organizational design affect the job-stress level. This happens because the organizational design determines how the organization or company will run its process. One of the non-organizational factors that cause stress is the personality type of the employees. This research will be examined the variables of organizational design and the personality type which affect the employee's stress level in the company. It suggests that employees' perception to the dimensions of organizational design significantly and positively affect the level of employees' work stress along with their personality type. In this case, those dimensions are formalization-authority, specialization, environment, work load-type of work, centralization-number of workers. The personality type is only considered as minor factor. Abstract in Bahasa Indonesia : Stres kerja dapat disebabkan oleh faktor-faktor organisasional maupun faktor-faktor non organisasional. Dimensi-dimensi disain organisasi memberikan pengaruh terhadap tingkat stres kerja. Hal ini terjadi disebabkan karena disain organisasi yang menentukan bagaimana sutau organisasi atau perusahaan menjalankan prosesnya. Salah satu faktor non organisasional yang dapat menyebabkan stres ialah tipe kepribadian dari karyawan. Di dalam penelitian ini akan diuji variabel-variabel disain organisasional dan tipe kepribadian yang mempengaruhi tingkat stres kerja karyawan di dalam perusahaan. Penelitian menyimpulkan bahwa persepsi karyawan terhadap dimensi-dimensi disain organisasional dan tipe kepribadiannya secara signifikan dan positif mempegaruhi tingkat stres kerja karyawan. Dalam hal ini, beberapa dimensi tersebut ialah formalisasi-wewenang, spesialisasi, lingkungan, beban kerja-tipe pekerjaan, sentralisasi-jumlah pekerja. Sementara itu tipe kepribadian merupakan faktor yang minor. Kata kunci: disain

  6. The EPOS ICT Architecture

    Jeffery, Keith; Harrison, Matt; Bailo, Daniele

    2016-04-01

    The EPOS-PP Project 2010-2014 proposed an architecture and demonstrated feasibility with a prototype. Requirements based on use cases were collected and an inventory of assets (e.g. datasets, software, users, computing resources, equipment/detectors, laboratory services) (RIDE) was developed. The architecture evolved through three stages of refinement with much consultation both with the EPOS community representing EPOS users and participants in geoscience and with the overall ICT community especially those working on research such as the RDA (Research Data Alliance) community. The architecture consists of a central ICS (Integrated Core Services) consisting of a portal and catalog, the latter providing to end-users a 'map' of all EPOS resources (datasets, software, users, computing, equipment/detectors etc.). ICS is extended to ICS-d (distributed ICS) for certain services (such as visualisation software services or Cloud computing resources) and CES (Computational Earth Science) for specific simulation or analytical processing. ICS also communicates with TCS (Thematic Core Services) which represent European-wide portals to national and local assets, resources and services in the various specific domains (e.g. seismology, volcanology, geodesy) of EPOS. The EPOS-IP project 2015-2019 started October 2015. Two work-packages cover the ICT aspects; WP6 involves interaction with the TCS while WP7 concentrates on ICS including interoperation with ICS-d and CES offerings: in short the ICT architecture. Based on the experience and results of EPOS-PP the ICT team held a pre-meeting in July 2015 and set out a project plan. The first major activity involved requirements (re-)collection with use cases and also updating the inventory of assets held by the various TCS in EPOS. The RIDE database of assets is currently being converted to CERIF (Common European Research Information Format - an EU Recommendation to Member States) to provide the basis for the EPOS-IP ICS Catalog.

    2002-04-01

    Drotrecogin alfa (Xigris, recombinant activated protein C) is an anticoagulant developed and launched by Eli Lilly & Co for the treatment of sepsis [333781], [339372], [430133], [436271]. The FDA and the EMEA accepted the brand name Xigris for drotrecogin alfa in June 2001. This trade name had been proposed by Lilly in place of the previous brand name, Zovant, which was deemed unacceptable by the EMEA due to concerns that the name could be confused with hospital-based drugs [412512]. Filings for sepsis were made in the US, EU and Australia in February 2001 [398514], [447870] and in March 2001, the US FDA assigned drotrecogin alfa Priority Review status [403435]. The FDA extended the action date from July 27 to October 27, 2001 for completion of its review of the biologics license application (BLA) for drotrecogin alfa to assess further supplementary data submitted by Lilly [412512]. At the October 16, 2001 meeting (postponed from September 12), the FDA Advisory Committee on Anti-Infective Drugs split 10 to 10 over whether to recommend approval [425873], [425940]. In late October 2001, Lilly received an approvable letter from the FDA for the treatment of severe sepsis. Approval was contingent upon successful negotiation of labeling, agreement on post-approval clinical trials, and successful completion of manufacturing inspections [427301]. In November 2001, the FDA approved drotrecogin alfa for the reduction of mortality in adult patients with severe sepsis who have a high risk of death [430133]; the product was launched onto the US market days later [436271]. Following the FDA committee's split decision in October 2001, Credit Suisse First Boston, which expected mid-2002 approval but with restrictive labeling, revised its predictions from $1.265 billion in 2004 sharply downwards to $543 million [425929].

    2017-04-01

    EPOS is now in IP (implementation phase) after a successful PP (preparatory phase). EPOS consists of essentially two components, one ICS (Integrated Core Services) representing the integrating ICT (Information and Communication Technology) and many TCS (Thematic Core Services) representing the scientific domains. The architecture developed, demonstrated and agreed within the project during the PP is now being developed utilising co-design with the TCS teams and agile, spiral methods within the ICS team. The 'heart' of EPOS is the metadata catalog. This provides for the ICS a digital representation of the TCS assets (services, data, software, equipment, expertise…) thus facilitating access, interoperation and (re-)use. A major part of the work has been interactions with the TCS. The original intention to harvest information from the TCS required (and still requires) discussions to understand fully the TCS organisational structures linked with rights, security and privacy; their (meta)data syntax (structure) and semantics (meaning); their workflows and methods of working and the services offered. To complicate matters further the TCS are each at varying stages of development and the ICS design has to accommodate pre-existing, developing and expected future standards for metadata, data, software and processes. Through information documents, questionnaires and interviews/meetings the EPOS ICS team has collected DDSS (Data, Data Products, Software and Services) information from the TCS. The ICS team developed a simplified metadata model for presentation to the TCS and the ICS team will perform the mapping and conversion from this model to the internal detailed technical metadata model using (CERIF: a EU recommendation to Member States maintained, developed and promoted by euroCRIS www.eurocris.org ). At the time of writing the final modifications of the EPOS metadata model are being made, and the mappings to CERIF designed, prior to the main phase of (meta

    The European Plate Observing System (EPOS) is integrating geoscientific information concerning earth movements in Europe. We are approaching the end of the PP (Preparatory Project) phase and in October 2014 expect to continue with the full project within ESFRI (European Strategic Framework for Research Infrastructures). The key aspects of EPOS concern providing services to allow homogeneous access by end-users over heterogeneous data, software, facilities, equipment and services. The e-infrastructure of EPOS is the heart of the project since it integrates the work on organisational, legal, economic and scientific aspects. Following the creation of an inventory of relevant organisations, persons, facilities, equipment, services, datasets and software (RIDE) the scale of integration required became apparent. The EPOS e-infrastructure architecture has been developed systematically based on recorded primary (user) requirements and secondary (interoperation with other systems) requirements through Strawman, Woodman and Ironman phases with the specification - and developed confirmatory prototypes - becoming more precise and progressively moving from paper to implemented system. The EPOS architecture is based on global core services (Integrated Core Services - ICS) which access thematic nodes (domain-specific European-wide collections, called thematic Core Services - TCS), national nodes and specific institutional nodes. The key aspect is the metadata catalog. In one dimension this is described in 3 levels: (1) discovery metadata using well-known and commonly used standards such as DC (Dublin Core) to enable users (via an intelligent user interface) to search for objects within the EPOS environment relevant to their needs; (2) contextual metadata providing the context of the object described in the catalog to enable a user or the system to determine the relevance of the discovered object(s) to their requirement - the context includes projects, funding, organisations

  13. Methods in ALFA Alignment

    CERN Document Server

    Melendez, Jordan

    2014-01-01

    This note presents two model-independent methods for use in the alignment of the ALFA forward detectors. Using a Monte Carlo simulated LHC run at \\beta = 90m and \\sqrt{s} = 7 TeV, the Kinematic Peak alignment method is utilized to reconstruct the Mandelstam momentum transfer variable t for single-diractive protons. The Hot Spot method uses fluctuations in the hitmap density to pinpoint particular regions in the detector that could signal a misalignment. Another method uses an error function fit to find the detector edge. With this information, the vertical alignment can be determined.

    Full Text Available Alfa, also known as Stipa tenacissimaI or “halfa”, is grown in North Africa and south Spain. Due to its short fiber length, paper made from alfa pulp retains bulk and takes block letters well. In this study alfa was evaluated for bleached pulp production. Two cellulose pulps with different chemical compositions were pulped by a conventional kraft process. One sample was taken from the original alfa material and another from alfa that had been pretreated by diluted acid. The pulp produced from the pretreated alfa was bleached by the elemental-chlorine-free sequences DEPD and DEDP. The yield, Kappa number, brightness, and α- cellulose content of bleached and unbleached pulps were evaluated. The results showed that during the chemical pulping process, treated alfa cooked more easily than the original alfa. The treated alfa pulp also showed very good bleaching, reaching a brightness level of 94.8% ISO with a yield of 93.6% at an α-cellulose content 96.8(% with a DEDP bleaching sequence, compared to 83.2% ISO brightness level, 92.8% yield, and 95.1% α-cellulose content for bleached pulp with a DEPD bleaching sequence. Therefore, this alfa material could be considered as a worthwhile choice for cellulosic fiber supply.

    FIN-EPOS consortium is a joint community of Finnish national research institutes tasked with operating and maintaining solid-earth geophysical and geological observatories and laboratories in Finland. These national research infrastructures (NRIs) seek to join EPOS research infrastructure (EPOS RI) and further pursue Finland's participation as a founding member in EPOS ERIC (European Research Infrastructure Consortium). Current partners of FIN-EPOS are the University of Helsinki (UH), the University of and Oulu (UO), Finnish Geospatial Research Institute (FGI) of the National Land Survey (NLS), Finnish Meteorological Institute (FMI), Geological Survey of Finland (GTK), CSC - IT Center for Science and MIKES Metrology at VTT Technical Research Centre of Finland Ltd. The consortium is hosted by the Institute of Seismology, UH (ISUH). The primary purpose of the consortium is to act as a coordinating body between various NRIs and the EPOS RI. FIN-EPOS engages in planning and development of the national EPOS RI and will provide support in EPOS implementation phase (IP) for the partner NRIs. FIN-EPOS also promotes the awareness of EPOS in Finland and is open to new partner NRIs that would benefit from participating in EPOS. The consortium additionally seeks to advance solid Earth science education, technologies and innovations in Finland and is actively engaging in Nordic co-operation and collaboration of solid Earth RIs. The main short term objective of FIN-EPOS is to make Finnish geoscientific data provided by NRIs interoperable with the Thematic Core Services (TCS) in the EPOS IP. Consortium partners commit into applying and following metadata and data format standards provided by EPOS. FIN-EPOS will also provide a national Finnish language web portal where users are identified and their user rights for EPOS resources are defined.

    Gene doping--or the abuse of gene therapy--will continue to threaten the sports world. History has shown that progress in medical research is likely to be abused in order to enhance human performance. In this review, we critically discuss the progress and the risks associated with the field of erythropoietin (EPO) gene therapy and its applicability to EPO gene doping. We present typical vector systems that are employed in ex vivo and in vivo gene therapy trials. Due to associated risks, gene doping is not a feasible alternative to conventional EPO or blood doping at this time. Nevertheless, it is well described that about half of the elite athlete population is in principle willing to risk its health to gain a competitive advantage. This includes the use of technologies that lack safety approval. Sophisticated detection approaches are a prerequisite for prevention of unapproved and uncontrolled use of gene therapy technology. In this review, we present current detection approaches for EPO gene doping, with a focus on blood-based direct and indirect approaches. Gene doping is detectable in principle, and recent DNA-based detection strategies enable long-term detection of transgenic DNA (tDNA) following in vivo gene transfer.

    The construction of seismological community services for the European Plate Observing System Research Infrastructure (EPOS) is by now well under way. A significant number of services are already operational, largely based on those existing at established institutions or collaborations like ORFEUS, EMSC, AHEAD and EFEHR, and more are being added to be ready for internal validation by late 2017. In this presentation we focus on a number of issues related to the interaction of the community of users with the services provided by the seismological part of the EPOS research infrastructure. How users interact with a service (and how satisfied they are with this interaction) is viewed as one important component of the validation of a service within EPOS, and certainly is key to the uptake of a service and from that also it's attributed value. Within EPOS Seismology, the following aspects of user interaction have already surfaced: - user identification (and potential tracking) versus ease-of-access and openness Requesting users to identify themselves when accessing a service provides various advantages to providers and users (e.g. quantifying & qualifying the service use, customization of services and interfaces, handling access rights and quotas), but may impact the ease of access and also shy away users who don't wish to be identified for whatever reason. - service availability versus cost There is a clear and prominent connection between the availability of a service, both regarding uptime and capacity, and its operational cost (IT systems and personnel), and it is often not clear where to draw the line (and based on which considerations). In connection to that, how to best utilize third-party IT infrastructures (either commercial or public), and what the long-term cost implications of that might be, is equally open. - licensing and attribution The issue of intellectual property and associated licensing policies for data, products and services is only recently gaining

    2015-04-01

    After the successful completion of the EPOS Preparatory Phase, the community of European Research Infrastructures in Seismology is now moving ahead with the build-up of the Thematic Core Service (TCS) for Seismology in EPOS, EPOS-Seismology. Seismology is a domain where European-level infrastructures have been developed since decades, often supported by large-scale EU projects. Today these infrastructures provide services to access earthquake waveforms (ORFEUS), parameters (EMSC) and hazard data and products (EFEHR). The existing organizations constitute the backbone of infrastructures that also in future will continue to manage and host the services of the TCS EPOS-Seismology. While the governance and internal structure of these organizations will remain active, and continue to provide direct interaction with the community, EPOS-Seismology will provide the integration of these within EPOS. The main challenge in the build-up of the TCS EPOS-Seismology is to improve and extend these existing services, producing a single framework which is technically, organizationally and financially integrated with the EPOS architecture, and to further engage various kinds of end users (e.g. scientists, engineers, public managers, citizen scientists). On the technical side the focus lies on four major tasks: - the construction of the next generation software architecture for the European Integrated (waveform) Data Archive EIDA, developing advanced metadata and station information services, fully integrate strong motion waveforms and derived parametric engineering-domain data, and advancing the integration of mobile (temporary) networks and OBS deployments in EIDA; - the further development and expansion of services to access seismological products of scientific interest as provided by the community by implementing a common collection and development (IT) platform, improvements in the earthquake information services e.g. by introducing more robust quality indicators and diversifying

    Amateur astronomers prime the public to be more interested, receptive, and excited about space science, missions, and programs. Through recent research and targeted programs, amateur astronomy outreach is being increasingly recognized by professional astronomers, educators, and other amateurs as a valued and important service. The Night Sky Network program, administered by the ASP, is the first nationwide research-based program specifically targeted to support outreach by amateur astronomers. This Network of trained and informed amateur astronomers can provide a stimulating introduction to your EPO programs as Network members share the night sky with families, students, and youth groups.

  2. Lessons learned from IRIS EPO program evaluations

    2012-12-01

    Evaluating the overall impact of EPO programs that include activities ranging from formal education through broad public outreach, is a complex issue. The impact of education activities targeted at narrowly defined audiences is generally easier to quantify than the national impact of outreach activities conducted by a relatively small program. For educational activities, our approach has been to leverage the best-practices identified through research and to continuously assess the individual elements internally with the intention of making improvements based on the data generated and the existing research. By constructing our elements on the best practices identified by the research community we feel that internal formative evaluation is a valid means to determine if an activity is effective, particularly when the results are compared to similar programs. For example, effective practices of professional development are well documented in the literature. As a result, this allows us to shape our programs and our evaluations to monitor elements that have been identified as key by the educational research community. Further, such actions allow us to avoid allocating significant resources with the intention of pinning down direct causal relationships between our programs and consumers, when similar interventions (conducted by others) have already shown such relationships. Ongoing review by an EPO advisory committee also provides regular oversight of program impact. While we find internal and external formative evaluation extremely useful in shaping the program and documenting its impact, we also recognize the value of a summative evaluation process.

Subjects and methods: A randomized, double-blind, two-sequence, crossover study was conducted. Subjects were randomly assigned to receive a single dose, that is, 4,000 IU, of the test or comparator epoetin alfa. After 4 weeks, all subjects received the alternative formulation. The primary PK parameters, maximum observed concentration (Cmax and area under the curve extrapolated to infinity (AUCinf, were calculated with the serum erythropoietin (EPO concentrations from blood samples collected for 144 h after dosing. The reticulocyte, hematocrit, hemoglobin and red blood cell counts were measured up to 312 h as PD markers. The primary PD parameters, maximum observed effect (Emax and area under the effect curve (AUEC, were obtained from the baseline-corrected reticulocyte count. The serum EPO concentration and the reticulocyte count were used to assess the concentration–response relationship. The tolerability and immunogenicity profiles were assessed together. Results: Forty-two subjects completed the study. The mean EPO concentration–time profiles were comparable between the two formulations. The geometric mean ratios (90% CI of the Cmax and AUCinf were 0.908 (0.843–0.978 and 1.049 (0.999–1.101, respectively, both of which were within the regulatory range of 0.80–1.25. Additionally, the PD and tolerability profiles were similar between the two

    The 1990-2010 period in professional cycling is labeled by some as the epo epidemic. Surprisingly, performance enhancement by epo and blood doping is not that clear-cut for endurance athletes, leading to the question whether doping indeed strongly influenced cyclists' performances from the 1990s onwards.

    Full Text Available Abstract Background Gonadotrophins are routinely administered in assisted reproductive technology (ART treatment protocols. Recombinant human follicle-stimulating hormone (r-hFSH; follitropin alfa and recombinant human luteinizing hormone (r-hLH; lutropin alfa can be administered individually or in a fixed combination. The ability to vary the FSH to LH dose ratio in a single injection without compromising the bioactivity of either gonadotrophin or generating losses of active principle is important for physicians and patients alike. Methods This study investigated whether follitropin alfa (GONAL-f (R, as lyophilized powder for reconstitution or solution from the GONAL-f (R (filled-by-mass [FbM] Prefilled Pen, could be used to reconstitute Pergoveris TM (follitropin alfa/lutropin alfa 150 IU/75 IU lyophilized powder. In Ratio Groups 1 and 2, the r-hFSH:r-hLH ratio was 3:1; in Ratio Groups 3 and 4, the ratios of r-hFSH:r-hLH were 5:1 and 8:1, respectively. The protein content and bioactivity of each mixed solution were evaluated. The r-hFSH and r-hLH content was determined using reverse-phase high performance liquid chromatography. The biological activity of r-hFSH and r-hLH was assessed using the Steelman-Pohley and Van Hell in vivo bioassays in rats, respectively. Results Follitropin alfa/lutropin alfa 150 IU/75 IU lyophilized powder could be successfully mixed with follitropin alfa 75 IU FbM solution that was either reconstituted from lyophilized powder or injected directly from the prefilled pen to create solutions with ratios of r-hFSH and r-hLH from 3:1 to 8:1. The measured content of r-hFSH and r-hLH corresponded favourably with the target protein content in Ratio Groups 1–4. The in vivo target and measured bioactivity of r-hFSH and r-hLH were also closely matched in all Ratio Groups. Conclusion Follitropin alfa lyophilized powder or solution can be accurately mixed with follitropin alfa/lutropin alfa 150 IU/75 IU lyophilized powder to

    The Absolute Luminosity For ATLAS (ALFA) experiment was designed to accurately measure the luminosity of the intersecting proton beams at the ATLAS interaction point [1]. However, the ALFA experiment has shifted its primary purpose from luminosity measurement to elastic and inelastic proton collisions. This change was the result of difficulty in fitting parameters in the region governed by Coulomb scattering. The operational principle for luminosity measurement with ALFA relied on detecting elastic proton collisions, so the detector is suited to its role in proton collision measurements. The ALFA detector consists of several sensitive components, including the main detector (MD), overlap detectors (ODs) and trigger tiles. A diagram of the ALFA detector is shown in Figure 1. The main detector is composed of layers of 0.5 × 0.5 mm2 cross section scintillating fibres with an active area of 0.48 × 0.48 mm2, which are directed diagonally across the detector with 64 fibres in each layer. The 20 total layers ar...

    European Plate Observation System - EPOS is a long-term plan to facilitate integrated use of data, models and facilities from mainly distributed existing, but also new, research infrastructures for solid Earth Science. In EPOS Preparatory Phase were integrated the national Research Infrastructures at pan European level in order to create the EPOS distributed research infrastructures, structure in which, at the present time, Romania participates by means of the earth science research infrastructures of the national interest declared on the National Roadmap. The mission of EPOS is to build an efficient and comprehensive multidisciplinary research platform for solid Earth Sciences in Europe and to allow the scientific community to study the same phenomena from different points of view, in different time periods and spatial scales (laboratory and field experiments). At national scale, research and monitoring infrastructures have gathered a vast amount of geological and geophysical data, which have been used by research networks to underpin our understanding of the Earth. EPOS promotes the creation of comprehensive national and regional consortia, as well as the organization of collective actions. To serve the EPOS goals, in Romania a group of National Research Institutes, together with their infrastructures, gathered in an EPOS National Consortium, as follows: 1. National Institute for Earth Physics - Seismic, strong motion, GPS and Geomagnetic network and Experimental Laboratory; 2. National Institute of Marine Geology and Geoecology - Marine Research infrastructure and Euxinus integrated regional Black Sea observation and early-warning system; 3. Geological Institute of Romania - Surlari National Geomagnetic Observatory and National lithoteque (the latter as part of the National Museum of Geology) 4.

  12. The Doppler paradigm and the APEX-EPOS-ORANGE quandary

    1995-01-01

    The experimental detection of the sharp lines of the (e + e - ) Puzzle is viewed as a struggle against Doppler broadening. Gedanken experiments which are realistic in zeroth order of detail are analyzed to show that the ORANGE and EPOS/I geometries select narrower slices of a Doppler broadened line than spherically inclusive (APEX and EPOS/II -like) apparati. Roughly speaking, the latter require event-by-event Doppler reconstruction simply to regain an even footing with the former. This suggests that APEX' or EPOS/II's coincident pair distributions must be statistically superior to those of EPOS/I or ORANGE in order to support a comparable inference about sharp structure. Under such circumstances, independent alternative data is invaluable. Therefore, a corroboration of Sakai's 330.1 keV ( + or e - bombardments of U and Th targets could prove crucial

  14. ALFA: an automated line fitting algorithm

    Science.gov (United States)

    Wesson, R.

    2016-03-01

    I present the automated line fitting algorithm, ALFA, a new code which can fit emission line spectra of arbitrary wavelength coverage and resolution, fully automatically. In contrast to traditional emission line fitting methods which require the identification of spectral features suspected to be emission lines, ALFA instead uses a list of lines which are expected to be present to construct a synthetic spectrum. The parameters used to construct the synthetic spectrum are optimized by means of a genetic algorithm. Uncertainties are estimated using the noise structure of the residuals. An emission line spectrum containing several hundred lines can be fitted in a few seconds using a single processor of a typical contemporary desktop or laptop PC. I show that the results are in excellent agreement with those measured manually for a number of spectra. Where discrepancies exist, the manually measured fluxes are found to be less accurate than those returned by ALFA. Together with the code NEAT, ALFA provides a powerful way to rapidly extract physical information from observations, an increasingly vital function in the era of highly multiplexed spectroscopy. The two codes can deliver a reliable and comprehensive analysis of very large data sets in a few hours with little or no user interaction.

    Combination therapy of Interferon alfa and ribavirin in chronic hepatitis C has well documented cutaneous adverse effects. Most interesting of these has been reported on hair physiology. This study was conducted to determine the frequency and pattern of adverse effects involving hair in patients receiving combination of interferon alfa 2a and ribavirin for chronic hepatitis C. The study was conducted in Department of Dermatology, Division of Medicine Shaikh Zayed Hospital. Thirty Eight patients who completed treatment with interferon alfa (3 MIU subcutaneously thrice weekly) and 1200 mg ribavirin daily for 24 weeks were enrolled in this single-center study. The patient's response and examination finding particularly regarding involvement of hair was noted on a Proforma. Thirty Two out of thirty eight (84%) patients noted adverse effects involving hair. The most frequent was diffuse hair loss and occurred in 27 patients (71%). Hypertrichosis of eyelashes (trichomegaly) and eyebrows (synophyrs) was observed in 18 (47%) and 16 (42%) patients respectively. Graying of hair was noted in 4 patients (11%), while discoloration of moustache hair was seen in 2 patients (5%). Epilation at the site of subcutaneous injection was noted in 10 patients (26%). Alopecia areata was reported in 2 patients (5%). It is concluded that adverse effects involving hair are frequent and varied (hair loss to excess hair growth) during combination therapy with Interferon alfa-2a and Ribavirin for chronic hepatitis C.

    Highlights: • New anti-human EPOR antibody confirms full-length EPOR expression in breast cancer cells. • Proliferation of breast cancer cells is not affected by rhEPO treatment in vitro. • EPOR knockdown impairs proliferation of ERa positive breast cancer cells. • EPOR knockdown reduces AKT phosphorylation and ERa activity. - Abstract: The main function of Erythropoietin (EPO) and its receptor (EPOR) is the stimulation of erythropoiesis. Recombinant human EPO (rhEPO) is therefore used to treat anemia in cancer patients. However, clinical trials have indicated that rhEPO treatment might promote tumor progression and has a negative effect on patient survival. In addition, EPOR expression has been detected in several cancer forms. Using a newly produced anti-EPOR antibody that reliably detects the full-length isoform of the EPOR we show that breast cancer tissue and cells express the EPOR protein. rhEPO stimulation of cultured EPOR expressing breast cancer cells did not result in increased proliferation, overt activation of EPOR (receptor phosphorylation) or a consistent activation of canonical EPOR signaling pathway mediators such as JAK2, STAT3, STAT5, or AKT. However, EPOR knockdown experiments suggested functional EPO receptors in estrogen receptor positive (ERα + ) breast cancer cells, as reduced EPOR expression resulted in decreased proliferation. This effect on proliferation was not seen in ERα negative cells. EPOR knockdown decreased ERα activity further supports a mechanism by which EPOR affects proliferation via ERα-mediated mechanisms. We show that EPOR protein is expressed in breast cancer cells, where it appears to promote proliferation by an EPO-independent mechanism in ERα expressing breast cancer cells

    One of the most important issues regarding a pan-European distributed large scale research infrastructure is the setting up of its legal and governance structure as this will shape the very operation of the undertaking, i.e. the decision-making process, the allocation of tasks and resources as well as the relationship between the different bodies. Ensuring long-term operational services requires a robust, coherent and transparent legal and governance framework across all of the EPOS TCS (Thematic Core Services) and ICS (Integrated Core Services) that is well aligned to the EPOS global architecture. The chosen model for the EPOS legal entity is the ERIC (European Research Infrastructure Consortium). While the statutory seat of EPOS-ERIC will be in Rome, Italy, most of the services will be hosted in other countries. Specific agreements between EPOS-ERIC and the legal bodies hosting EPOS services will be implemented to allow proper coordination of activities. The objective is to avoid multiple agreements and, where possible, to standardize them in order to reach a harmonized situation across all services. For the governance careful attention will be paid to the decision-making process, the type of decisions and the voting rights, the definition of responsibilities, rights and duties, the reporting mechanisms, as well as other issues like who within a TCS represents the service to the 'outside' world or who advices the TCS on which subjects. Data policy is another crucial issue as EPOS aims to provide interdisciplinary services to researchers interested in geoscience, including access to data, metadata, data products, software and IT tools. EPOS also provides access to computational resources for visualization and processing. Beyond the general principles of Open Access and Open Source the following questions have to be addressed: scope and nature of data that will be accepted; intellectual property rights in data and terms under which data will be shared; openness and

    EPOS brings together European nations and combines solid Earth science infrastructures and their associated data and services together with the scientific expertise into one integrated delivery system for solid Earth science. By improving and facilitating the integration, access, use, and re-use of solid Earth science data, data products, services and facilities EPOS is developing a holistic, sustainable, multidisciplinary research platform to provide coordinated access to harmonized and quality controlled data from diverse Earth science disciplines, together with tools for their use in analysis and modelling. EPOS has been designed with the vision of creating a single distributed pan-European infrastructure for solid Earth science to support a safe and sustainable society. In accordance with this scientific vision, the EPOS mission is to integrate the diverse and advanced European Research Infrastructures for solid Earth relying on new e-science opportunities to monitor and unravel the dynamic and complex Earth System. EPOS is presently in its implementation phase, which consists of the EPOS IP project and the legal establishment of EPOS-ERIC. The EPOS Implementation Phase builds on the achievements of the successful EPOS Preparatory Phase project. The EPOS implementation phase will last from 2015 to 2019. The key objectives of the project are: implementing Thematic Core Services (TCS), the domain-specific service hubs for coordinating and harmonizing national resources/plans with the European dimension of EPOS; building the Integrated Core Services (ICS) to provide a novel research platform to different stakeholders; designing the access to distributed computational resources (ICS-D); ensuring sustainability and governance of TCS and EPOS-ERIC. Here we present the activities planned for the implementation phase focusing on the TCS, the ICS and on their interoperability. We will present and discuss the data and service provision focusing on the data, data

    A new collaboration among the NASA Science Mission Directorate (SMD) Astrophysics EPO community is to engage girls in science who do not self-select as being interested in science, through the library setting. The collaboration seeks to (i) improve how girls view themselves as someone who knows about, uses, and sometimes contributes to science, and (ii) increase the capacity of EPO practitioners and librarians (both school and public) to engage girls in science. As part of this collaboration, we are collating the research on audience needs and best practices, and SMD EPO resources, activities and projects that focus on or can be recast toward engaging girls in science. This ASP article highlights several available resources and individual projects, such as: (i) Afterschool Universe, an out-of-school hands-on astronomy curriculum targeted at middle school students and an approved Great Science for Girls curriculum; (ii) Big Explosions and Strong Gravity, a Girl Scout patch-earning event for middle school aged girls to learn astronomy through hands-on activities and interaction with actual astronomers; and (iii) the JWST-NIRCAM Train the Trainer workshops and activities for Girl Scouts of USA leaders; etc. The NASA Astrophysics EPO community welcomes the broader EPO community to discuss with us how best to engage non-science-attentive girls in science, technology, engineering, and mathematics (STEM), and to explore further collaborations on this theme.

    Full Text Available OBJECTIVES: Transfusion of allogeneic blood is still common in orthopedic surgery. This analysis evaluates from the perspective of a German hospital the potential cost savings of Epoetin alfa (EPO compared to predonated autologous blood transfusions or to a nobloodconservationstrategy (allogeneic blood transfusion strategyduring elective hip and knee replacement surgery. METHODS: Individual patients (N = 50,000 were simulated based on data from controlled trials, the German DRG institute (InEK and various publications and entered into a stochastic model (Monte-Carlo of three treatment arms: EPO, preoperative autologous donation and nobloodconservationstrategy. All three strategies lead to a different risk for an allogeneic blood transfusion. The model focused on the costs and events of the three different procedures. The costs were obtained from clinical trial databases, the German DRG system, patient records and medical publications: transfusion (allogeneic red blood cells: €320/unit and autologous red blood cells: €250/unit, pneumonia treatment (€5,000, and length of stay (€300/day. Probabilistic sensitivity analyses were performed to determine which factors had an influence on the model's clinical and cost outcomes. RESULTS: At acquisition costs of €200/40,000 IU EPO is cost saving compared to autologous blood donation, and cost-effective compared to a nobloodconservationstrategy. The results were most sensitive to the cost of EPO, blood units and hospital days. CONCLUSIONS: EPO might become an attractive blood conservation strategy for anemic patients at reasonable costs due to the reduction in allogeneic blood transfusions, in the modeled incidence of transfusion-associated pneumonia andthe prolongedlength of stay.

    Full Text Available Human erythropoietin is mainly recognized for its hematopoietic function; however, by binding to its receptor (EpoR, it can activate different signaling pathways as STAT, PI3K, MAPK and RAS to increase cellular differentiation or provide neuroprotective effects, among others. A recombinant human erythropoietin variant with low glycosylation and without hematopoietic effect (EpoL was purified from skimmed goat milk. Recombinant human erythropoietin (Epo was obtained from CHO cell line and used as control to compare EpoL effects. Neuroprotection studies were performed in PC12 cells and rat hippocampal slices. Cells were pretreated during 1 h with EpoL or Epo and exposed to oxidative agents (H2O2 or FCCP; cell viability was assayed at the end of the experiment by the MTT method. Hippocampal slices were exposed to 15 min of oxygen and glucose deprivation (OGD and the neuroprotective drugs EpoL or Epo were incubated for 2 h post-OGD in re-oxygenated medium. Cell cultures stressed with oxidative agents, and pretreated with EpoL, showed neuroprotective effects of 30% at a concentration 10 times lower than that of Epo. Moreover, similar differences were observed in OGD ex vivo assays. Neuroprotection elicited by EpoL was lost when an antibody against EpoR was present, indicating that its effect is EpoR-dependent. In conclusion, our results suggest that EpoL has a more potent neuroprotective profile than Epo against oxidative stress, mediated by activation of EpoR, thus EpoL represents an important target to develop a potential biopharmaceutical to treat different central nervous system pathologies related to oxidative stress such as stroke or neurodegenerative diseases.

    2017-01-01

    The ALFA_CTPIN module has been designed in response to increased internal processing time of the Central Trigger Processor (CTP) of the ATLAS experiment which resulted in reducing time left to the ALFA detector to deliver its own triggers to the CTP within specified latency. Accelerated extraction of ALFA triggers from encoded signals and the possibility to perform local triggers processing by this module allowed ALFA to contribute to global triggering of the ATLAS detector. A huge number of implemented scalers and flexibility in defining triggers processing criteria make also from this module a very attractive tool for in-depth analysis of properties of the LHC beam.

    A method for the routine determination of alpha-emitting plutonium in urine is described. In evolving this procedure various techniques for concentrating, purifying and electro depositing plutonium were compared, and these investigations are summarized. In the procedure finally adopted, urine is wet-ashed and the residue dissolved in hydrochloric acid. Plutonium (IV) is co-precipitated with iron cupferride from this solution and extracted into chloroform. After evaporation of the chloroform, the residue is oxidized, dissolved in hydrochloric acid and the iron extracted into di-isopropyl ether. The aqueous phase containing the plutonium is evaporated and dissolved in an acid ammonium sulphate solution from which the plutonium is electrodeposited onto stainless steel. Quantitative recoveries are obtained over the electrodeposition stage and on overall recovery of 84 {+-} 7%. The electrodeposited plutonium is counted with a solid-state (silicon junction diode) detector in a counter developed for this purpose. The low inherent background of this type of counter is effectively reduced still further by counting only those alpha particles with energy in the 4.2 - 5.4 MeV range. The good resolution which can be obtained with thin electrodeposited sources of plutonium enables this narrow channel to be used with only small losses in counting efficiency. By counting over this restricted energy range, the blank activity arising from reagents and incomplete removal of alpha-emitting contaminants in urine is also reduced by a factor of two, to just over 0.01 pc/24-h sample. The limit of detection with this method is about 0.025 pc of Pu{sup 239}.

  6. Epo receptors are not detectable in primary human tumor tissue samples.

    Full Text Available Erythropoietin (Epo is a cytokine that binds and activates an Epo receptor (EpoR expressed on the surface of erythroid progenitor cells to promote erythropoiesis. While early studies suggested EpoR transcripts were expressed exclusively in the erythroid compartment, low-level EpoR transcripts were detected in nonhematopoietic tissues and tumor cell lines using sensitive RT-PCR methods. However due to the widespread use of nonspecific anti-EpoR antibodies there are conflicting data on EpoR protein expression. In tumor cell lines and normal human tissues examined with a specific and sensitive monoclonal antibody to human EpoR (A82, little/no EpoR protein was detected and it was not functional. In contrast, EpoR protein was reportedly detectable in a breast tumor cell line (MCF-7 and breast cancer tissues with an anti-EpoR polyclonal antibody (M-20, and functional responses to rHuEpo were reported with MCF-7 cells. In another study, a functional response was reported with the lung tumor cell line (NCI-H838 at physiological levels of rHuEpo. However, the specificity of M-20 is in question and the absence of appropriate negative controls raise questions about possible false-positive effects. Here we show that with A82, no EpoR protein was detectable in normal human and matching cancer tissues from breast, lung, colon, ovary and skin with little/no EpoR in MCF-7 and most other breast and lung tumor cell lines. We show further that M-20 provides false positive staining with tissues and it binds to a non-EpoR protein that migrates at the same size as EpoR with MCF-7 lysates. EpoR protein was detectable with NCI-H838 cells, but no rHuEpo-induced phosphorylation of AKT, STAT3, pS6RP or STAT5 was observed suggesting the EpoR was not functional. Taken together these results raise questions about the hypothesis that most tumors express high levels of functional EpoR protein.

    EPOS Thematic Core Service ANTHROPOGENIC HAZARDS (TCS AH) aims to integrate distributed research infrastructures (RI) to facilitate and stimulate research on anthropogenic hazards (AH) especially those associated with the exploration and exploitation of geo-resources. The innovative element is the uniqueness of the integrated RI which comprises two main deliverables: (1) Exceptional datasets, called "episodes", which comprehensively describe a geophysical process; induced or triggered by human technological activity, posing hazard for populations, infrastructure and the environment, (2) Problem-oriented, bespoke services uniquely designed for the discrimination and analysis of correlations between technology, geophysical response and resulting hazard. These objectives will be achieved through the Science-Industry Synergy (SIS) built by EPOS WG10, ensuring bi-directional information exchange, including unique and previously unavailable data furnished by industrial partners. The Episodes and services to be integrated have been selected using strict criteria during the EPOS PP. The data are related to a wide spectrum of inducing technologies, with seismic/aseismic deformation and production history as a minimum data set requirement and the quality of software services is confirmed and referenced in literature. Implementation of TCS AH is planned for four years and requires five major activities: (1) Strategic Activities and Governance: will define and establish the governance structure to ensure the long-term sustainability of these research infrastructures for data provision through EPOS. (2) Coordination and Interaction with the Community: will establish robust communication channels within the whole TCS AH community while supporting global EPOS communication strategy. (3) Interoperability with EPOS Integrated Core Service (ICS) and Testing Activities: will coordinate and ensure interoperability between the RIs and the ICS. Within this modality a functional e

    An important outcome of the 4-year Preparatory Phase of the ESFRI project European Plate Observing System (EPOS) was the development and first implementation of the EPOS Demonstrator by the project's ICT Working Group 7. The Demonstrator implements the vertical integration of the three-layer architectural scheme for EPOS, connecting the Integrated Core Services (ICS), Thematic Core Services (TCS) and the National Research Infrastructures (NRI). The demonstrator provides a single GUI with central key discovery and query functionalities, based on already existing services by the seismic, geologic and geodetic communities. More specifically the seismic services of the Demonstrator utilize webservices and APIs for data and discovery of raw seismic data (FDSN webservices by the EIDA Network), events (Geoportal by EMSC) and analytical data products (e.g., hazard maps by EFEHR via OGC WMS). For geologic services, the EPOS Demonstrator accesses OneGeology Europe which serves the community with geologic maps and point information via OGC webservices. The Demonstrator also provides access to raw geodetic data via a newly developed universal tool called GSAC. The Demonstrator itself resembles the future Integrated Core Service (ICS) and provides direct access to the end user. Its core functionality lies in a metadata catalogue, which serves as the central information hub and stores information about all RIs, related persons, projects, financial background and technical access information. The database schema of the catalogue is based on CERIF, which has been slightly adapted. Currently, the portal provides basic query functions as well as cross domain search. [www.epos.cineca.it

    2017-04-01

    The European Plate Observing System (EPOS) aims to create a pan-European infrastructure for solid Earth science to support a safe and sustainable society. The main vision of the European Plate Observing System (EPOS) is to address the three basic challenges in Earth Science: (i) unravelling the Earth's deformational processes which are part of the Earth system evolution in time, (ii) understanding geo-hazards and their implications to society, and (iii) contributing to the safe and sustainable use of geo-resources. The mission of EPOS-Norway is therefore in line with the European vision of EPOS, i.e. monitor and understand the dynamic and complex Earth system by relying on new e-science opportunities and integrating diverse and advanced Research Infrastructures for solid Earth science. The EPOS-Norway project started in January 2016 with a national consortium consisting of six institutions. These are: University of Bergen (Coordinator), NORSAR, National Mapping Authority, Geological Survey of Norway, Christian Michelsen Research and University of Oslo. EPOS-N will during the next five years focus on the implementation of three main components. These are: (i) Developing a Norwegian e-Infrastructure to integrate the Norwegian Solid Earth data from the seismological and geodetic networks, as well as the data from the geological and geophysical data repositories, (ii) Improving the monitoring capacity in the Arctic, including Northern Norway and the Arctic islands, and (iii) Establishing a national Solid Earth Science Forum providing a constant feedback mechanism for improved integration of multidisciplinary data, as well as training of young scientists for future utilization of all available solid Earth observational data through a single e-infrastructure. Currently, a list of data, data products, software and services (DDSS) is being prepared. These elements will be integrated in the EPOS-N data/web-portal, which will allow users to browse, select and download

  14. The EPOS Vision for the Open Science Cloud

    Science.gov (United States)

    Jeffery, Keith; Harrison, Matt; Cocco, Massimo

    2016-04-01

    Cloud computing offers dynamic elastic scalability for data processing on demand. For much research activity, demand for computing is uneven over time and so CLOUD computing offers both cost-effectiveness and capacity advantages. However, as reported repeatedly by the EC Cloud Expert Group, there are barriers to the uptake of Cloud Computing: (1) security and privacy; (2) interoperability (avoidance of lock-in); (3) lack of appropriate systems development environments for application programmers to characterise their applications to allow CLOUD middleware to optimize their deployment and execution. From CERN, the Helix-Nebula group has proposed the architecture for the European Open Science Cloud. They are discussing with other e-Infrastructure groups such as EGI (GRIDs), EUDAT (data curation), AARC (network authentication and authorisation) and also with the EIROFORUM group of 'international treaty' RIs (Research Infrastructures) and the ESFRI (European Strategic Forum for Research Infrastructures) RIs including EPOS. Many of these RIs are either e-RIs (electronic-RIs) or have an e-RI interface for access and use. The EPOS architecture is centred on a portal: ICS (Integrated Core Services). The architectural design already allows for access to e-RIs (which may include any or all of data, software, users and resources such as computers or instruments). Those within any one domain (subject area) of EPOS are considered within the TCS (Thematic Core Services). Those outside, or available across multiple domains of EPOS, are ICS-d (Integrated Core Services-Distributed) since the intention is that they will be used by any or all of the TCS via the ICS. Another such service type is CES (Computational Earth Science); effectively an ICS-d specializing in high performance computation, analytics, simulation or visualization offered by a TCS for others to use. Already discussions are underway between EPOS and EGI, EUDAT, AARC and Helix-Nebula for those offerings to be

    EPOS - the European Plate Observing System - is the ESFRI infrastructure serving the need of the solid Earth science community at large. The EPOS mission is to create a single sustainable, and distributed infrastructure that integrates the diverse European Research Infrastructures for solid Earth science under a common framework. Thematic Core Services (TCS) and Integrated Core Services (Central Hub, ICS-C and Distributed, ICS-D) are key elements, together with NRIs (National Research Infrastructures), in the EPOS architecture. Following the preparatory phase, EPOS has initiated formal steps to adopt an ERIC legal framework (European Research Infrastructure Consortium). The statutory seat of EPOS will be in Rome, Italy, while the ICS-C will be jointly operated by France, UK and Denmark. The TCS planned so far cover: seismology, near-fault observatories, GNSS data and products, volcano observations, satellite data, geomagnetic observations, anthropogenic hazards, geological information modelling, multiscale laboratories and geo-energy test beds for low carbon energy. In the ERIC process, EPOS and all its services must achieve sustainability from a legal, governance, financial, and technical point of view, as well as full harmonization with national infrastructure roadmaps. As EPOS is a distributed infrastructure, the TCSs have to be linked to the future EPOS ERIC from legal and governance perspectives. For this purpose the TCSs have started to organize themselves as consortia and negotiate agreements to define the roles of the different actors in the consortium as well as their commitment to contribute to the EPOS activities. The link to the EPOS ERIC shall be made by service agreements of dedicated Service Providers. A common EPOS data policy has also been developed, based on the general principles of Open Access and paying careful attention to licensing issues, quality control, and intellectual property rights, which shall apply to the data, data products

    With greater and greater emphasis on the inclusion of a public engagement component in all government-supported research funding, many members of the DPS are finding it difficult to find sufficient time and funding to develop a wide-reaching and effective E/PO program. NASA's Office of Space Science, over the last five years, has built a Support Network to assist its funded scientists to establish partnerships with local and/or national science formal or informal education organizations, who are anxious to connect with and use the expertise of space scientists. The OSS Support Network consists of four theme-based 'Forums,' including the Solar System Exploration (SSE) Forum, specifically designed for working with planetary scientists, and seven regional 'Brokers-Facilitators' who are more familiar with partnership and other potential avenues for involvement by scientists. The services provided by the Support Network are free to both the scientists and their potential partners and is not limited to NASA-funded scientists. In addition to its assistance to space scientists, the Support Network is involved in a number of other overarching efforts, including support of a Solar System Ambassador Program, a Solar System Educator Program, Space Place (web and e-mail science products for libraries and small planetariums and museums), an on-line Space Science Resource Directory, annual reports of Space Science E/PO activity, identifying and filling in 'holes' and 'over-populations' in a solar system E/PO product matrix of grade level versus product versus content, research on product effectiveness, and scientific and educational evaluation of space science products. Forum and Broker-Facilitator contact information is available at http://spacescience.nasa.gov/education/resources/ecosystem/index.htm. Handouts with additional information will be available at the meeting.

    The participant countries in EPOS embody a wide range of world-class laboratory infrastructures ranging from high temperature and pressure experimental facilities, to electron microscopy, micro-beam analysis, analogue modeling and paleomagnetic laboratories. Most data produced by the various laboratory centres and networks are presently available only in limited "final form" in publications. Many data remain inaccessible and/or poorly preserved. However, the data produced at the participating laboratories are crucial to serving society's need for geo-resources exploration and for protection against geo-hazards. Indeed, to model resource formation and system behaviour during exploitation, we need an understanding from the molecular to the continental scale, based on experimental data. This contribution will describe the plans that the laboratories community in Europe is making, in the context of EPOS. The main objectives are: • To collect and harmonize available and emerging laboratory data on the properties and processes controlling rock system behaviour at multiple scales, in order to generate products accessible and interoperable through services for supporting research activities. • To co-ordinate the development, integration and trans-national usage of the major solid Earth Science laboratory centres and specialist networks. The length scales encompassed by the infrastructures included range from the nano- and micrometer levels (electron microscopy and micro-beam analysis) to the scale of experiments on centimetre sized samples, and to analogue model experiments simulating the reservoir scale, the basin scale and the plate scale. • To provide products and services supporting research into Geo-resources and Geo-storage, Geo-hazards and Earth System Evolution. If the EPOS Implementation Phase proposal presently under construction is successful, then a range of services and transnational activities will be put in place to realize these objectives.

    The approach to earthquake prediction by geophysical, geochemical and hydrological measurements is a long and winding road. Nevertheless, the results show a progress in that field (e.g. Kobe). This progress is also a result of a new generation of measuring equipment. SARAD has developed a versatile measuring system (EPOS1) based on experiences and recent results from different research groups. It is able to record selected parameters suitable to earthquake prediction research. A micro-computer system handles data exchange, data management and control. It is connected to a modular sensor system. Sensor modules can be selected according to the actual needs at the measuring site. (author)

    2011-12-01

    My "day job" is numerical modeling of the interiors of the terrestrial planets, but I have also done EPO projects for the last 17 years while at the Lunar and Planetary Institute. These range from single, hour long talks in classrooms or astronomy clubs, to week-long summer workshops for teachers and librarians, and even semester-long programs, along with a number of curriculum development projects. EPO projects are a great way to help develop both the next generation of scientists and, more importantly, of scientifically literate citizens and taxpayers. Here are a few lessons learned along the way in the school of hard knocks. (1) An engaging delivery style is even more important in EPO presentations than it is in college lectures or conference presentations. Emphasize a few key concepts rather than numerous facts, and keep the jargon out. Good analogies can go a long way towards explaining a concept to any age group. I teach the role of size in planetary cooling by first asking students how long it takes to cook food of various sizes (a hamburger, roast beef, turkey). (2) If you will be working with a group of students for more than one class period, classroom friendly activities strengthen the learning process. Such activities do not need to be elaborate - when teaching about the Moon, I sometimes assign students to take their parents outside at night and show them how to find lava flows on the Moon. Teachers usually need to have classroom activities that are aligned to state or national teaching standards. Fortunately, many effective, standards-aligned activities already exist, so you don't need to reinvent the wheel. For a useful listing of planetary science and astronomy activities, see the LPI website www.lpi.usra.edu/education/resources/ (3) Although EPO work can be personally rewarding, it is not always well rewarded in a professional context, and it can be difficult to find the time and financial resources to sustain major projects.

    The European Plate Observing System (EPOS) has a scientific vision and approach aimed at creating a pan-European infrastructure for Earth sciences to support a safe and sustainable society. To follow this vision, the EPOS mission is integrating a suite of diverse and advanced Research Infrastructures (RIs) in Europe relying on new e-science opportunities to monitor and understand the dynamic and complex Earth system. To this goal, the EPOS Preparatory Phase has designed a long-term plan to facilitate integrated use of data and products as well as access to facilities from mainly distributed existing and new research infrastructures for solid Earth Science. EPOS will enable innovative multidisciplinary research for a better understanding of the Earth's physical processes that control earthquakes, volcanic eruptions, ground instability and tsunami as well as the processes driving tectonics and Earth surface dynamics. Through integration of data, models and facilities EPOS will allow the Earth Science community to make a step change in developing new concepts and tools for key answers to scientific and socio-economic questions concerning geo-hazards and geo-resources as well as Earth sciences applications to the environment and to human welfare. Since its conception EPOS has been built as "a single, Pan-European, sustainable and distributed infrastructure". EPOS is, indeed, the sole infrastructure for solid Earth Science in ESFRI and its pan-European dimension is demonstrated by the participation of 23 countries in its preparatory phase. EPOS is presently moving into its implementation phase further extending its pan-European dimension. The EPOS Implementation Phase project (EPOS IP) builds on the achievements of the successful EPOS preparatory phase project. The EPOS IP objectives are synergetic and coherent with the establishment of the new legal subject (the EPOS-ERIC in Italy). EPOS coordinates the existing and new solid Earth RIs within Europe and builds the

  7. Managing anemia with epoetin alfa in patients with rectal cancer

    International Nuclear Information System (INIS)

    2005-01-01

    Background. Anemia is one of the most challenging problems in clinical oncology due to its high prevalence among the patients with malignant diseases. The purposes of our study were: (1) to assess the potential of epoetin alfa therapy to prevent the decline in Hb concentrations that typically accompanies chemotherapy/ radiotherapy (ChT/RT) of the patients with rectal cancer; (2) to test the hypothesis that the use of epoetin alfa significantly reduces the transfusion requirements in the patients with rectal cancer treated with ChT/RT after surgery, and (3) to evaluate the safety profile of the administration of epoetin alfa in the clinical setting. Methods. Sixty patients who underwent surgery for rectal cancer were prospectively enrolled. Group A consisted of 39 patients with Hb concentrations ≤13 g/dl at the start of ChT/RT following surgery, and group B of 17 patients with Hb concentrations ≥13 g/dl at the start of ChT/RT following surgery, but whose Hb concentrations fell below 13 g/dl during the ChT/RT protocol. The starting dose of epoetin alfa in both groups was 10,000 IU subcutaneously (sc) three times a week (tiw). The following major parameters were evaluated: (1) change in Hb concentrations relative to the baseline as measured at 4-week intervals, (2) allogenic blood transfusion requirements in relation to Hb concentrations, and (3) incidence and severity of adverse events and their potential relationship to epoetin alfa administration. Results. The study protocol was completed in 56/60 patients. In group A, a statistically significant increase in Hb concentration (p<0.001) was observed after the first 4 weeks of epoetin alfa treatment compared to the baseline values, with the mean increase of Hb concentration of 1.97 g/dl ± 0.91 g/dl and Hb concentrations remained significantly increased through the whole study (p=0.0017).

    Treatment with peginterferon alfa and ribavirin produces a sustained virologic response (SVR) in approximately 60% of hepatitis C virus (HCV)-infected patients. Alternate options are needed for patients who relapse or do not respond to therapy. This prospective, international, multicenter, open-label study evaluated efficacy and safety of peginterferon alfa-2b (1.5 microg/kg/wk) plus weight-based ribavirin (800-1400 mg/day) in 2333 chronic HCV-infected patients with significant fibrosis/cirrhosis whose previous interferon alfa/ribavirin therapy failed. Patients with undetectable HCV-RNA at treatment week (TW) 12 received 48 weeks of therapy; patients with detectable HCV-RNA at TW12 could enter maintenance studies at TW18; 188 patients with low/detectable HCV-RNA at TW12 continued therapy at the investigator's request. Overall, 22% of the patients attained SVR (56% with undetectable HCV-RNA and 12% with low/detectable HCV-RNA at TW12). SVR was better in relapsers (38%) than nonresponders (14%), regardless of previous treatment, and in patients previously treated with interferon-alfa/ribavirin (25%) than peginterferon alfa-ribavirin (17%). Predictors of response in patients with undetectable HCV-RNA at TW12 were genotype (2/3 vs 1, respectively; odds ratio [OR] 2.4; P 600,000 IU/mL; OR, 1.4; P = .0223). These factors plus previous treatment and response were overall predictors of SVR. Safety was similar among fibrosis groups. Peginterferon alfa-2b plus weight-based ribavirin is effective and safe in patients who failed interferon alfa/ribavirin therapy. Genotype, baseline viral load, and fibrosis stage were predictors of response.

    EPOS has been designed with the vision of creating a pan-European infrastructure for solid Earth science to support a safe and sustainable society. In accordance with this scientific vision, the EPOS mission is to integrate the diverse and advanced European Research Infrastructures for solid Earth science relying on new e-science opportunities to monitor and unravel the dynamic and complex Earth System. EPOS will enable innovative multidisciplinary research for a better understanding of the Earth's physical and chemical processes that control earthquakes, volcanic eruptions, ground instability and tsunami as well as the processes driving tectonics and Earth's surface dynamics. To accomplish its mission, EPOS is engaging different stakeholders, not limited to scientists, to allow the Earth sciences to open new horizons in our understanding of the planet. EPOS also aims at contributing to prepare society for geo-hazards and to responsibly manage the exploitation of geo-resources. Through integration of data, models and facilities, EPOS will allow the Earth science community to make a step change in developing new concepts and tools for key answers to scientific and socio-economic questions concerning geo-hazards and geo-resources as well as Earth sciences applications to the environment and human welfare. A long-term integration plan is necessary to accomplish the EPOS mission. EPOS is presently in its implementation phase further extending its pan-European dimension. The EPOS Implementation Phase builds on the achievements of the successful EPOS Preparatory Phase project and consists of two key activities: the legal establishment of the EPOS-ERIC and the EPOS IP project. The EPOS implementation phase will last from 2015 to 2019. Key objectives of the project are: implementing Thematic Core Services (TCS), the domain-specific service hubs for coordinating and harmonizing national resources/plans with the European dimension of EPOS; building the Integrated Core

    My report as Summer Student is in two parts. In the first part I report about my attendance to the run of the ALFA detector to test different collimation schemas and find a new way to get rid of the background. The second part is about the measurement of the resolution of the ALFA detector and comparing the real data with the Monte-Carlo (MC) simulations. First of all I tried to be more familiar with ROOT, worked on understanding the code used to access to the data in the trees inside the Ntuples, plotting histograms,… This was done using old Ntuples which contain MC data.

    EPOS (the ELBE POsitron Source) is a running project to build an intense, bunched positron beam for materials research. It makes use of the bunched electron beam of the ELBE radiation source (Electron Linac with high Brilliance and low Emittance) at the Research Centre Dresden-Rossendorf (40 MeV, 1 mA). ELBE has unique timing properties, the bunch length is <5 ps and the repetition time is 77 ns. In contrast to other Linacs made for Free Electron Lasers (e.g., TTF at DESY, Hamburg), ELBE can be operated in full cw-mode, i.e., with an uninterrupted sequence of bunches. The article continues an earlier publication. It concentrates on details of the timing system and describes issues of radiation protection

    A modification of the sensitive agar diffusion method was developed for macro-scale determination of alfa-amylase. The proposed modifications lower costs with the utilisation of starch as substrate and agar as supporting medium. Thus, a standard curve was built using alfa-amylase solution from Aspergillus oryzae, with concentrations ranging from 2.4 to 7,500 U.mL-1. Clear radial diffusion zones were measured after 4 hours of incubation at 20 °C. A linear relationship between the logarithm of...

    WG4 - "EPOS Geodetic Data and Other Geodetic Data" is the Working Group of the EPOS project in charge of defining and preparing the integration of the existing Pan-European Geodetic Infrastructures that will support European Geosciences, which is the ultimate goal of the EPOS project. The WG4 is formed by representatives of the participating EPOS countries (23) but it is also open to the entire geodetic community. In fact, WG4 also already includes members from countries that formally are not integrating EPOS in this first step. The geodetic component of EPOS (WG4) is dealing essentially with Research Infrastructures focused on continuous operating GNSS (cGNSS) in the current phase. The option of concentrating the efforts on the presently most generalized geodetic tool supporting research on Solid Earth was decided in order to optimize the existing resources. Nevertheless, WG4 will continue to pursue the development of tools and methodologies that permit the access of the EPOS community to other geodetic information (e.g., gravimetry). Furthermore, although the focus is on Solid Earth applications, other research and technical applications (e.g., reference frames, meteorology, space weather) can also benefit from the efforts of WG4 EPOS towards the optimization of the geodetic resources in Europe. We will present and discuss the plans for the implementation of the thematic and core services (TCS) for geodetic data within EPOS and the related business plan. We will focus on strategies towards the implementation of the best solutions that will permit to the end-users, and in particular geo-scientists, to access the geodetic data, derived solutions, and associated metadata using transparent and uniform processes. Five pillars have been defined proposed for the TCS: Dissemination, Preservation, Monitoring, and Analysis of geodetic data plus the Support and Governance Infrastructure. Current proposals and remaining open questions will be discussed.

    Clear cell renal cell carcinoma (ccRCC) is the most common subtype of renal carcinomas. There is great interest to know the molecular basis of the tumor biology of ccRCC that might contribute to a better understanding of the aggressive biological behavior of this cancer and to identify early biomarkers of disease. This study describes the relationship among proliferation, survival, and apoptosis with the expression of key molecules related to tumoral hypoxia (hypoxia-inducible factor (HIF)-1α, erythropoietin (EPO), vascular endothelial growth factor (VEGF)), their receptors (EPO-R, VEGFR-2), and stearoyl desaturase-1 (SCD-1) in early stages of ccRCC. Tissue samples were obtained at the Urology Unit of the J.R. Vidal Hospital (Corrientes, Argentina), from patients who underwent radical nephrectomy for renal cancer between 2011 and 2014. Four experimental groups according to pathological stage and nuclear grade were organized: T1G1 (n = 6), T2G1 (n = 4), T1G2 (n = 7), and T2G2 (n = 7). The expression of HIF-1α, EPO, EPO-R, VEGF, VEGFR-2, Bcl-x L , and SCD-1 were evaluated by immunohistochemistry, Western blotting, and/or RT-PCR. Apoptosis was assessed by the TUNEL in situ assay, and tumor proliferation was determined by Ki-67 immunohistochemistry. Data revealed that HIF-1α, EPO, EPO-R, VEGF, and VEGF-R2 were overexpressed in most samples. The T1G1 group showed the highest EPO levels, approximately 200 % compared with distal renal tissue. Bcl-x L overexpression was concomitant with the enhancement of proliferative indexes. SCD-1 expression increased with the tumor size and nuclear grade. Moreover, the direct correlations observed between SCD-1/HIF-1α and SCD-1/Ki-67 increments suggest a link among these molecules, which would determine tumor progression in early stages of ccRCC. Our results demonstrate the relationship among proliferation, survival, and apoptosis with the expression of key molecules related to tumoral hypoxia (HIF-1α, EPO, VEGF), their

    The commonalities between the ALICE and FAIR experiments and their computing requirements led to the development of large parts of a common software framework in an experiment independent way. The FairRoot project has already shown the feasibility of such an approach for the FAIR experiments and extending it beyond FAIR to experiments at other facilities[1, 2]. The ALFA framework is a joint development between ALICE Online- Offline (O2) and FairRoot teams. ALFA is designed as a flexible, elastic system, which balances reliability and ease of development with performance using multi-processing and multithreading. A message- based approach has been adopted; such an approach will support the use of the software on different hardware platforms, including heterogeneous systems. Each process in ALFA assumes limited communication and reliance on other processes. Such a design will add horizontal scaling (multiple processes) to vertical scaling provided by multiple threads to meet computing and throughput demands. ALFA does not dictate any application protocols. Potentially, any content-based processor or any source can change the application protocol. The framework supports different serialization standards for data exchange between different hardware and software languages.

    Following the European Plate Observing System (EPOS) project vision aimed at creating a pan-European infrastructure for Earth sciences to support science for a more sustainable society, we are working on the integration of Near-Fault Observatories (NFOs). NFOs are state of the art research infrastructures consisting of advanced networks of multi-parametric sensors continuously monitoring the chemical and physical processes related to the common underlying earth instabilities governing active faults evolution and the genesis of earthquakes. Such a methodological approach, currently applicable only at the local scale (areas of tens to few hundreds of kilometres), is based on extremely dense networks and less common instruments deserving an extraordinary work on data quality control and multi-parameter data description. These networks in fact usually complement regional seismic and geodetic networks (typically with station spacing of 50-100km) with high-density distributions of seismic, geodetic, geochemical and geophysical sensors located typically within 10-20 km of active faults where large earthquakes are expected in the future. In the initial phase of EPOS-IP, seven NFO nodes will be linked: the Alto Tiberina and Irpinia Observatories in Italy, the Corinth Observatory in Greece, the South-Iceland Seismic Zone, the Valais Observatory in Switzerland, Marmara Sea GEO Supersite in Turkey (EU MARSite) and the Vrancea Observatory in Romania. Our work is aimed at establishing standards and integration within this first core group of NFOs while other NFOs are expected to be installed in the next years adopting the standards established and developed within the EPOS Thematic Core Services (TCS). The goal of our group is to build upon the initial development supported by these few key national observatories coordinated under previous EU projects (NERA and REAKT), inclusive and harmonised TCS supporting the installation over the next decade of tens of near

    Participation in outreach events is an easy way for scientists to get involved with E/PO and reach many people with minimal time commitment. At the Lunar and Planetary Institute (LPI) in Houston, Texas, the E/PO team holds Sky Fest outreach events several times a year. These events each have a science content theme and include several activities for children and their parents, night sky viewing through telescopes, and scientist presentations. LPI scientists have the opportunity to participate in Sky Fest events either by helping lead an activity or by giving the scientist presentation (a short lecture and/or demonstration). Scientists are involved in at least one preparation meeting before the event. This allows them to ask questions, understand what activity they will be leading, and learn the key points that they should be sharing with the public, as well as techniques for effectively teaching members of the public about the event topic. During the event, each activity is run by one E/PO specialist and one scientist, enabling the scientist to learn about effective E/PO practices from the E/PO specialist and the E/PO specialist to get more science information about the event topic. E/PO specialists working together with scientists at stations provides a more complete, richer experience for event participants. Surveys of event participants have shown that interacting one-on-one with scientists is often one of their favorite parts of the events. Interviews with scientists indicated that they enjoyed Sky Fest because there was very little time involved on their parts outside of the actual event; the activities were created and/or chosen by the E/PO professionals, and setup for the events was completed before they arrived. They also enjoyed presenting their topic to people without a background in science, and who would not have otherwise sought out the information that was presented.

    Animals respond to hypoxia by increasing synthesis of the glycoprotein hormone erythropoietin (Epo) which in turn stimulates the production of red blood cells. The gene encoding Epo has been recently cloned in teleost fishes such as the pufferfish Takifugu rubripes (fugu) and zebrafish (Danio rerio). It has been shown that the transcription levels of Epo in teleost fishes increase in response to anemia or hypoxia in a manner similar to its human ortholog. However, the cis-regulatory element(s) mediating the hypoxia response of Epo gene in fishes has not been identified. In the present study, using the human hepatoma cell line (Hep3B), we have identified and characterized a hypoxia response element (HRE) in the fugu Epo locus. The sequence of the fugu HRE (ACGTGCTG) is identical to that of the HRE in the human EPO locus. However, unlike the HRE in the mammalian Epo locus, which is located in the 3' region of the gene, the fugu HRE is located in the 5' flanking region and on the opposite strand of DNA. This HRE is conserved in other teleosts such as Tetraodon and zebrafish in a similar location. A 365-bp fragment containing the fugu HRE was able to drive GFP expression in the liver of transgenic zebrafish. However, we could not ascertain if the expression of transgene is induced by hypoxia in vivo due to the low and variable levels of GFP expression in transgenic zebrafish. Our investigations also revealed that the Epo locus has experienced extensive rearrangements during vertebrate evolution. Copyright © 2010 Elsevier B.V. All rights reserved.

    In the course of examination of the positron and positron-electron pair emission from heavy ion collisions at the Coulomb barrier, the research groups EPOS I and ORANGE have found a number of line structures in the measured positron energy and cumulative pair energy spectra which up to present could not be fully explained, as theoretical interpretations so far remain inconsistent in some respects. For clarification, further measurements have been made at the completely new designed EPoS II spectrometer. Reproducibility of the lines is possible at a high level of statistical significance.

    Full Text Available Hideo Orimo Division of Metabolism and Nutrition, Department of Biochemistry and Molecular Biology, Nippon Medical School, Tokyo, Japan Abstract: Hypophosphatasia (HPP is an inherited systemic bone disease that is characterized by bone hypomineralization. HPP is classified into six forms according to the age of onset and severity as perinatal (lethal, perinatal benign, infantile, childhood, adult, and odontohypophosphatasia. The causative gene of the disease is the ALPL gene that encodes tissue-nonspecific alkaline phosphatase (TNAP. TNAP is expressed ubiquitously, and its physiological role is apparent in bone mineralization. A defect in bone mineralization can manifest in several ways, including rickets or osteomalacia in HPP patients. Patients with severe forms suffer from respiratory failure because of hypoplastic chest, which is the main cause of death. They sometimes present with seizures due to a defect in vitamin B6 metabolism resulting from the lack of alkaline phosphatase activity in neuronal cells, which is also lethal. Patients with a mild form of the disease exhibit rickets or osteomalacia and a functional defect of exercise. Odontohypophosphatasia shows only dental manifestations. To date, 302 mutations in the ALPL gene have been reported, mainly single-nucleotide substitutions, and the relationships between phenotype and genotype have been partially elucidated. An established treatment for HPP was not available until the recent development of enzyme replacement therapy. The first successful enzyme replacement therapy in model mice using a modified human TNAP protein (asfotase alfa was reported in 2008, and subsequently success in patients with severe form of the disease was reported in 2012. In 2015, asfotase alfa was approved in Japan in July, followed by in the EU and Canada in August, and then by the US Food and Drug Administration in the USA in October. It is expected that therapy with asfotase alfa will drastically change

    Early experience with the operation of the ALFA detectors in the LHC environment has shown significant beam-induced heating. Comprehensive studies on the effects of heating with a spare detector module have furthermore revealed that heating effects could be disastrous in the case of the larger beam intensities foreseen for higher luminosity. A temporary solution was implemented and kept the detectors below the critical temperature in 2012. In LS1 all ALFA stations have been removed from LHC and are undergoing an upgrade of the geometry of Roman Pots to minimize the impedance losses. When the stations were re-installed ~4 m distance was added between them to gain level arm in the angular measurement between the stations. The updated geometry of the Roman Pot, together with a system to improve the internal heat transfer and an air cooling system, is expected to keep the temperatures of ALFA detectors below critical limits throughout the LHC Run2 and first results from the performance in 2016 will be presented. ...

    The ALFA detector system (Absolute Luminosity For ATLAS) aims for measuring the absolute LHC luminosity with high precision by using pp-scattering under small angles. Scintillating fibers tracking detectors are positioned 240 m from LHC interaction point 1 inside Roman Pots at millimeter distance from the LHC beam axis. The detectors consist of layers of 64 scintillating square fibers of 500 µm size in a U-V configuration. The layers are staggered 10 times to improve the spatial resolution to about 30 micrometers. A total of 11680 scintillating fibers are read out on the 8 ALFA detectors through 184 Multi Anode Photomultiplier Tubes, MAPMTs, of type Hamamatsu R7600-00-M64, 64 channels. Each detector has dedicated scintillating trigger tiles read out by 8 mm Hamamatsu Photomultiplier Tubes (R7400P and R9880U-110) via clear fibers. The gain of the MAPMTs differs up to a factor 3 inside a MAPMT and an additional factor 2 between different MAPMTs. For compensation, ALFA has developed a front-end electronic based...

    EPOS-IP WP10 - "GNSS Data & Products" is the Working Package 10 of the European Plate Observing System - Implementation Phase project in charge of implementing services for the geo-sciences community to access existing Pan-European Geodetic Infrastructures. WP10 is currently formed by representatives of participating European institutions but in the operational phase contributions will be solicited from the entire geodetic community. In fact, WP10 also includes members from other institutions/countries that formally are not participating in the EPOS-IP but will be key players in the future services to be provided by EPOS. Additionally, several partners are also key partners at EUREF, which is also actively collaborating with EPOS. The geodetic component of EPOS is dealing essentially with implementing an e-infrastructure to store and disseminate the continuous GNSS data from existing Research Infrastructures. Present efforts are on developing geodetic tools to support Solid Earth research by optimizing the existing resources. However, other research and technical applications (e.g., reference frames, meteorology, space weather) can also benefit in the future from the optimization of the geodetic resources in Europe. We present and discuss the status of the implementation of the thematic and core services (TCS) for GNSS data within EPOS and the related business plan. We explain the tools and web-services being developed towards the implementation of the best solutions that will permit to the end-users, and in particular geo-scientists, to access the geodetic data, derived solutions, and associated metadata using a transparent and standardized processes. We also detail the different DDSS (Data, Data-Products, Services, Software) that will be made available for the Operational Phase of EPOS, which will start to be tested and made available during 2017 and 2018.

  9. The Use of Soluble Transferrin Receptor in the Detection of rHuEPO abuse in Sports

    Full Text Available Erythropoietin (EPO increases the number of circulating erythrocytes and muscle oxygenation. The recombinant forms of EPO have indiscriminately been used by athletes, mainly in endurance sports to increase their erythrocytes concentration, thus generating a better delivery of oxygen to the muscle tissue. The administration of recombinant human erythropoietin (rHuEPO except for therapeutic use was prohibited by the International Olympic Committee (IOC and its unauthorized use considered as doping. In the last few years, a number of studies using parameters indicative of accelerated erythropoiesis have investigated a number of indirect methods for the detection of rHuEPO abuse. No single indirect marker has been found that can satisfactorily demonstrated rHuEPO misuse. Soluble transferrin receptor (sTfR is a new marker of iron status and erythropoietic activity. It has been included in multivariable blood testing models for the detection of performance enhancing EPO abuse in sports. Indirect markers of altered erythropoiesis give reliable evidence of current or discontinued rHuEPO usage. This review describes the physical, biological and pharmacokinetic properties of endogenous EPO and its recombinant form. It also discusses the available strategies for the detection of rHuEPO abuse in sports, involving the use of sTfR concentration directly or in mathematical multivariate models.

    Brain Erythropoietin (EPO), an important neurotrophic factor and neuroprotective factor, was found to be associated with aging. Studies found EPO expression was significantly decreased in the hippocampus of aging rat compared with that of the youth. But mechanisms of the decline of the brain EPO during aging remain unclear. The present study utilized a d-galactose (d-gal)-induced aging model in which the inducement of aging was mainly oxidative injury, to explore underlying mechanisms for the decline of brain EPO in aging rats. d-gal-induced aging rats (2months) were simulated by subcutaneously injecting with d-gal at doses of 50mg·kg(-1), 150mg·kg(-1) and 250mg·kg(-1) daily for 8weeks while the control group received vehicle only. These groups were all compared with the aging rats (24months) which had received no other treatment. The cognitive impairment was assessed using Morris water maze (MWM) in the prepared models, and the amount of β-galactosidase, the lipid peroxidation product malondialdehyde (MDA) level and the superoxide dismutase (SOD) activity in the hippocampus was examined by assay kits. The levels of EPO, EPOR, p-JAK2 and hypoxia-inducible factor-2α (HIF-2α) in the hippocampus were detected by western blot. Additionally, the correlation coefficient between EPO/EPOR expression and MDA level was analyzed. The MWM test showed that compared to control group, the escape latency was significantly extended and the times of crossing the platform was decreased at the doses of 150mg·kg(-1) and 250mg·kg(-1) (paging rats, the expressions of EPO, EPOR, p-JAK2, and HIF-2αin the brain of d-gal-treated rats were significantly decreased (paging could result in the decline of EPO in the hippocampus and oxidative stress might be the main reason for the decline of brain EPO in aging rats, involved with the decrease of HIF-2α stability.

    2007-01-01

    To assess worldwide development of nanotechnology, this paper compares the numbers and contents of nanotechnology patents in the United States Patent and Trademark Office (USPTO), European Patent Office (EPO), and Japan Patent Office (JPO). It uses the patent databases as indicators of nanotechnology trends via bibliographic analysis, content map analysis, and citation network analysis on nanotechnology patents per country, institution, and technology field. The numbers of nanotechnology patents published in USPTO and EPO have continued to increase quasi-exponentially since 1980, while those published in JPO stabilized after 1993. Institutions and individuals located in the same region as a repository's patent office have a higher contribution to the nanotechnology patent publication in that repository ('home advantage' effect). The USPTO and EPO databases had similar high-productivity contributing countries and technology fields with large number of patents, but quite different high-impact countries and technology fields after the average number of received cites. Bibliographic analysis on USPTO and EPO patents shows that researchers in the United States and Japan published larger numbers of patents than other countries, and that their patents were more frequently cited by other patents. Nanotechnology patents covered physics research topics in all three repositories. In addition, USPTO showed the broadest representation in coverage in biomedical and electronics areas. The analysis of citations by technology field indicates that USPTO had a clear pattern of knowledge diffusion from highly cited fields to less cited fields, while EPO showed knowledge exchange mainly occurred among highly cited fields

    2000-01-01

    Epoxidised palm oil (EPO) resin can be cured by ultraviolet (UV) radiation either by radical, cationic or hybrid system. Cationic curing system has been chosen in this study due to the fact that epoxy groups present in EPO can be utilised directly to form crosslinking. Curing was done by means of a 20 cm wide UV IST machine with the conditions of 7.5 A current and 4 m/min conveyor speed. Sulphonium and ferrocenium salts were used as cationic photoinitiator. A formulations study was performed on the selected grades of EPO with other materials. These include types and concentration of photoinitiator, monomers, concentration of EPO and post-cure. The properties of the cured film such as pendulum hardness, percentage of gel content and tensile strength were determined. It was found that triarylsulphonium hexafluorophosphate has a very low solubility in EPO. Addition of vinyl ether monomer to the formulation did not enhance pendulum hardness and gel content of the cured films. It is also found that the post cure temperature has no significant effect on the cured film

    Electrolytic plasma processes (EPP) can be used for cleaning, metal-coating, carburizing, nitriding, and oxidizing. Electrolytic plasma oxidizing (EPO) is an advanced technique to deposit thick and hard ceramic coatings on a number of aluminum alloys. However, the EPO treatment on Al-Si alloys with a high Si content has rarely been reported. In this research, an investigation was conducted to clarify the effects of silicon contents on the EPO coating formation, morphology, and composition. Cast hypereutectic 390 alloys (∼ 17% Si) and hypoeutectic 319 alloys (∼ 7% Si) were chosen as substrates. The coating morphology, composition, and microstructure of the EPO coatings on those substrates were investigated using scanning electron microscopy (SEM) with energy dispersive X-ray (EDX) analysis and X-ray diffraction (XRD). A stylus roughness tester was used for surface roughness measurement. It was found that the EPO process had four stages where each stage was corresponding to various coating surface morphology, composition, and phase structures, characterised by different coating growth mechanisms

  15. Mass spectrometric analysis of EPO IEF-PAGE interfering substances in nitrile examination gloves.

    Direct detection of doping with recombinant erythropoietins (rhEPO) is accomplished by isoelectric focusing (IEF) or sodium dodecylsulfate (SDS) polyacrylamide gel electrophoresis (PAGE). In a recent publication, Lasne et al. (Electrophoresis 2011, 32, 1444) showed that improper use of nitrile examination gloves during sample collection, sample preparation, and IEF-PAGE may lead to distorted or absent EPO IEF-profiles. In order to clarify which substances are responsible for this observation, a mass spectrometric study on water extractable compounds found in nitrile gloves was performed. Several substance classes were shown to be present, among them polyethylene glycols (PEG), anionic and nonionic surfactants, as well as alcohol ethoxylates and plasticizers. It could be demonstrated that alkylbenzenesulfonates, the main category of detectable anionic detergents, and among them sodium dodecylbenzenesulfonate (SDBS) and its homologs, are the prime reason for the interference of nitrile gloves with EPO IEF-PAGE.

    The European Plate Observing System (EPOS) aims to create a pan-European infrastructure for solid Earth science to support a safe and sustainable society. The main vision of the European Plate Observing System (EPOS) is to address the three basic challenges in Earth Sciences: (i) unravelling the Earth's deformational processes which are part of the Earth system evolution in time, (ii) understanding the geo-hazards and their implications to society, and (iii) contributing to the safe and sustainable use of geo-resources. The mission of EPOS is to monitor and understand the dynamic and complex Earth system by relying on new e-science opportunities and integrating diverse and advanced Research Infrastructures in Europe for solid Earth Science. EPOS will enable innovative multidisciplinary research for a better understanding of the Earth's physical and chemical processes that control earthquakes, volcanic eruptions, ground instability and tsunami as well as the processes driving tectonics and Earth's surface dynamics. EPOS will improve our ability to better manage the use of the subsurface of the Earth. Through integration of data, models and facilities EPOS will allow the Earth Science community to make a step change in developing new concepts and tools for key answers to scientific and socio-economic questions concerning geo-hazards and geo-resources as well as Earth sciences applications to the environment and to human welfare. EPOS has now started its Implementation Phase (EPOS-IP). One of the main challenges during the implementation phase is the integration of multidisciplinary data into a single e-infrastructure. Multidisciplinary data are organized and governed by the Thematic Core Services (TCS) and are driven by various scientific communities encompassing a wide spectrum of Earth science disciplines. These include Data, Data-products, Services and Software (DDSS), from seismology, near fault observatories, geodetic observations, volcano observations

    2016-04-01

    The EPOS-IP WP10 - "GNSS Data & Products" is the Working Package of the EPOS-IP project in charge of implementing the necessary services in order that the geo-sciences community can access the existing Pan-European Geodetic Infrastructures. The WP10 is formed by representatives of the participating institutions (10) but it is also open to the entire geodetic community. In fact, WP10 also includes members from other institutions/countries that formally are not participating in the EPOS-IP. During the EPOS-IP project, the geodetic component of EPOS (WP10) is dealing essentially with Research Infrastructures focused on continuous operating GNSS (cGNSS). The option of concentrating the efforts on the presently most generalized geodetic tool supporting research on Solid Earth was decided in order to optimize the existing resources. Furthermore, although the focus is on Solid Earth applications, other research and technical applications (e.g., reference frames, meteorology, space weather) can also benefit from the efforts of WP10 towards the optimization of the geodetic resources in Europe. We will present and discuss the plans for the implementation of the thematic and core services (TCS) for GNSS data within EPOS and the related business plan. We will focus on strategies towards the implementation of the best solutions that will permit to the end-users, and in particular geo-scientists, to access the geodetic data, derived solutions, and associated metadata using transparent and uniform processes. The collaboration with EUREF is also an essential component of the implementation plan.

    2016-04-01

    Drotrecogin alfa was a landmark drug for treatment of severe sepsis, yet little is known about how it was adopted and de-adopted during its 10-year period of availability. We used hospitalization data on fee-for-service Medicare beneficiaries from 2002 to 2011 to characterize trends in the use of drotrecogin alfa in the United States. Drotrecogin alfa use peaked at 5.87 per 1000 severe sepsis hospitalizations in 2003 and then steadily declined to 0.94 administrations per 1000 severe sepsis hospitalizations in 2010. Large teaching hospitals were more likely to use drotrecogin alfa than small, nonteaching hospitals. The addition of "add-on payments" to hospitals for using drotrecogin alfa in 2002 was associated with significantly increased use (P publication of international sepsis guidelines with favorable drotrecogin alfa recommendations (in 2004 and 2008) nor the publication of a clinical trial focused on drotrecogin alfa (in 2005) were associated with consistent changes use (P > .05). Drotrecogin alfa use declined over time, with marked changes in use associated with drug-specific financial incentives but not the publication of clinical practice guidelines or clinical trials.

  19. Pathophysiology of hypophosphatasia and the potential role of asfotase alfa.

    Science.gov (United States)

    2016-01-01

    Hypophosphatasia (HPP) is an inherited systemic bone disease that is characterized by bone hypomineralization. HPP is classified into six forms according to the age of onset and severity as perinatal (lethal), perinatal benign, infantile, childhood, adult, and odontohypophosphatasia. The causative gene of the disease is the ALPL gene that encodes tissue-nonspecific alkaline phosphatase (TNAP). TNAP is expressed ubiquitously, and its physiological role is apparent in bone mineralization. A defect in bone mineralization can manifest in several ways, including rickets or osteomalacia in HPP patients. Patients with severe forms suffer from respiratory failure because of hypoplastic chest, which is the main cause of death. They sometimes present with seizures due to a defect in vitamin B6 metabolism resulting from the lack of alkaline phosphatase activity in neuronal cells, which is also lethal. Patients with a mild form of the disease exhibit rickets or osteomalacia and a functional defect of exercise. Odontohypophosphatasia shows only dental manifestations. To date, 302 mutations in the ALPL gene have been reported, mainly single-nucleotide substitutions, and the relationships between phenotype and genotype have been partially elucidated. An established treatment for HPP was not available until the recent development of enzyme replacement therapy. The first successful enzyme replacement therapy in model mice using a modified human TNAP protein (asfotase alfa) was reported in 2008, and subsequently success in patients with severe form of the disease was reported in 2012. In 2015, asfotase alfa was approved in Japan in July, followed by in the EU and Canada in August, and then by the US Food and Drug Administration in the USA in October. It is expected that therapy with asfotase alfa will drastically change treatments and prognosis of HPP.

    I worked on the ALFA project, which has the aim to measure the total cross section in PP collisions as a function of t, the momentum transfer by measuring the scattering angle of the protons. This measurement is done for all available energies; so far 7, 8 and 13 TeV. There are many analysis steps and we have focused on enhancing the signal-to-noise ratio. First of all I tried to be more familiar with ROOT, worked on understanding the code used to access to the data, plotting histograms, then cutting-off background.

    Full Text Available A modification of the sensitive agar diffusion method was developed for macro-scale determination of alfa-amylase. The proposed modifications lower costs with the utilisation of starch as substrate and agar as supporting medium. Thus, a standard curve was built using alfa-amylase solution from Aspergillus oryzae, with concentrations ranging from 2.4 to 7,500 U.mL-1. Clear radial diffusion zones were measured after 4 hours of incubation at 20 °C. A linear relationship between the logarithm of enzyme activities and the area of clear zones was obtained. The method was validated by testing α-amylase from barley at the concentrations of 2.4; 60; 300 and 1,500 U.mL-1. The proposed method turned out to be simpler, faster, less expensive and able to determine on a macro-scale α-amylase over a wide range (2.4 to 7,500 U.mL-1 in scientific investigation as well as in teaching laboratory activities.Modificações foram propostas ao método sensível de difusão em ágar para a macrodeterminação de alfa-amilase. As modificações propostas diminuem os custos, com a utilização de amido como substrato e ágar como meio solidificante. Assim, foi construída uma curva padrão utilizando uma solução de alfa-amilase de Aspergillus oryzae com concentrações variando de 2,4 a 7.500 U.mL-1. Em seguida, as zonas claras de difusão radial foram mensuradas depois de 4 horas de incubação a 20 °C. Foi obtida uma relação linear entre o logaritmo da atividade enzimática e os diâmetros das zonas claras. O método foi validado utilizando-se soluções de alfa-amilase de cevada nas concentrações de 2,4; 60; 300 e 1.500 U.mL-1. O método tornou-se mais simples, rápido, com baixo custo e passível de ser utilizado para macrodeterminação de alfa-amilase em ampla faixa (2,4 a 7.500 U.mL-1 na investigação científica e para fins didáticos em aulas práticas.

    Full Text Available Abstract Background and Aims Erythropoietin (EPO is a glycoprotein hormone which is required to regulate the production of red blood cells. Deficiency of EPO is known to cause anemia in chronically infected renal patients and they require regular blood transfusion. Availability of recombinant EPO has eliminated the need for blood transfusion and now it is extensively used for the treatment of anemia. Glycosylation of erythropoietin is essential for its secretion, stability, protein conformation and biological activity. However, maintenance of human like glycosylation pattern during manufacturing of EPO is a major challenge in biotechnology. Currently, Chinese hamster ovary (CHO cell line is used for the commercial production of erythropoietin but this cell line does not maintain glycosylation resembling human system. With the trend to eliminate non-human constituent from biopharmaceutical products, as a preliminary approach, we have investigated the potential of human hepatoma cell line (Huh-7 to produce recombinant EPO. Materials and methods Initially, the secretory signal and Kozak sequences was added before the EPO mature protein sequence using overlap extension PCR technique. PCR-amplified cDNA fragments of EPO was inserted into mammalian expression vector under the control of the cytomegalovirus (CMV promoter and transiently expressed in CHO and Huh-7 cell lines. After RT-PCR analysis, ELISA and Western blotting was performed to verify the immunochemical properties of secreted EPO. Results Addition of secretory signal and Kozak sequence facilitated the extra-cellular secretion and enhanced the expression of EPO protein. Significant expression (P Conclusion Huh-7 cell line has a great potential to produce glycosylated EPO, suggesting the use of this cell line to produce glycoproteins of the therapeutic importance resembling to the natural human system.

    Within power-generating plants, the transfer and conversion of heat energy of very large quantity are carried out in the process of energy conversion, accordingly the importance of heat exchangers is very high. Heretofore, multi-tube heat exchangers have been used mostly, but Alfa-Laval group developed the heat exchanger with very high efficiency to incorporate it effectively into a power-generating plant. In this plate type heat exchanger, the heat transfer efficiency is very high, and the quantity of stagnation is small as it is compact, consequently it is suitable to the secondary cooling for power-generating plant or the heat exchange of high-priced liquid heat media such as heavy water. Originally, plate type heat exchangers were used for food and chemical industries, therefore the prevention of mixing two liquids, sanitary construction, and corrosion resistance were required. Then they were adopted in iron and steel industry, and large thermal load, large heat transfer area and corrosion resistance to sea water were required. They were adopted in a nuclear power plant for the first time in 1964. In this heat exchanger, channels are formed with corrugated metal sheets, and titanium, stainless steels, Incoloy, Hastelloy and others are used as occasion demands. The Alfa-Laval heat exchangers and their features are explained. (Kako, I.)

    In recent years, there are growing trends in using vegetables oil as raw materials in resin production. Development of new products from palm oil derivatives such as epoxidised palm oil (EPO) is of particular interest to this country. The compatibility of EPO with cycloaliphatic diepoxide allows the development of a wide range of radiation curable formulations by cationic photoinitiators. Curing was done by means of a 20 cm wide IST UV, machine with the conditions of 7.5A current and 4 m/min conveyor speed. Sulphonium and ferrocenium salts were used as the cationic photoinitiators. A study was formulated to compromise the investigation of various effects on the cured film properties. These effects include; types and concentration of photoinitiators, formulating ratios, reactive diluents, photosensitizers and postcuring conditions. The effects on the gel fraction, pendulum hardness, tensile strength and elongation at break were investigated. The results showed that 30% of EPO was the maximum value that can be used in the formulation. It was also found that triarylsulphonium hexafluorophosphate has a very low solubility in EPO

    Alginates are the most employed biomaterials for cell encapsulation due to their abundance, easy gelling properties and apparent biocompatibility. However, as natural polymers different impurities including endotoxins, proteins and polyphenols can be found in their composition. Several purification protocols as well as different batteries of assays to prove the biocompatibility of the alginates in vitro have been recently developed. However, little is known about how the use of alginates with different purity grade may affect the host immune response after their implantation in vivo. The present paper investigates the long-term functionality and biocompatibility of murine erythropoietin (EPO) secreting C2C12 cells entrapped in microcapsules elaborated with alginates with different properties (purity, composition and viscosity). Results showed that independently of the alginate type employed, the animals presented elevated hematocrit levels until day 130, remaining at values between 70-87%. However, histological analysis of the explanted devices showed higher overgrowth around non-biomedical grade alginate microcapsules which could be directly related with higher impurity content of this type of alginate. Although EPO delivery may be limited by the formation of a fibrotic layer around non-biomedical grade alginate microcapsules, the high EPO secretion of the encapsulated cells together with the pharmacodynamic behaviour and the angiogenic and immune-modulatory properties of EPO result in no direct correlation between the biocompatibility of the alginate and the therapeutic response obtained.

    1990-11-01

    Two years ago the Bonn Electron Stretcher Accelerator ELSA came into operation. Although the control system proved to be a valuable tool for operating the machine, there did not exist any high level application software dealing with beam diagnostics, orbit measurement and closed orbit correction. To cover these main fields of machine physics, a new program 'EPOS' was implemented on top of the existing control system. EPOS integrates data aquisition, beam diagnostics, digitial signal processing and automation of measurement and control in one interactive environment. The system is equipped with a new, easy to use programming language for machine physics and data analysis. EPOS is based on X-windows and can generate high quality diagrams and printouts for all kinds of measured or simulated data. The design and implementation of EPOS is sketched in this document. Its functionality is demonstrated by performing automatic measurements of the ELSA tune with high precision. By using a special method for error correction, the obtained precision can be increased by approximately two orders of magnitude, compared to standard Fourier analysis techniques. The resulting tune values for standard ELSA operating modes are discussed in detail. (orig.) [de

    The Exploration Systems Mission Directorate, Directorate Integration Office conducts analog field test activities, such as Desert Research and Technology Studies (DRATS), to validate exploration system architecture concepts and conduct technology demonstrations. Education and Public Outreach (EPO) activities have been a part of DRATS missions in the past to engage students, educators, and the general public in analog activities. However, in 2010, for the first time, EPO was elevated as a principal task for the mission and metrics were collected for all EPO activities. EPO activities were planned well in advance of the mission, with emphasis on creating a multitude of activities to attract students of all ages. Web-based and social media interaction between August 31 and September 14, 2010 resulted in 62,260 DRATS Flickr views; 10,906 views of DRATS videos on YouTube; 1,483 new DRATS Twitter followers; and a 111% increase in DRATS Facebook fan interactions. Over 7,000 outreach participants were directly involved in the DRATS 2010 analog mission via student visitations at both the integrated dry-runs prior to the field mission and during the field mission; by participating in live, interactive webcasts and virtual events; and online voting to determine a traverse site as part of the NASA initiative for Participatory Exploration (PE).

    EPOS, the European Plate Observing System, is a long-term plan to facilitate the integrated use of data, data products, software and services, available from distributed Research Infrastructures (RI), for solid Earth science in Europe. Indeed, EPOS integrates a large number of existing European RIs belonging to several fields of the Earth science, from seismology to geodesy, near fault and volcanic observatories as well as anthropogenic hazards. The EPOS vision is that the integration of the existing national and trans-national research infrastructures will increase access and use of the multidisciplinary data recorded by the solid Earth monitoring networks, acquired in laboratory experiments and/or produced by computational simulations. The establishment of EPOS will foster the interoperability of products and services in the Earth science field to a worldwide community of users. Accordingly, the EPOS aim is to integrate the diverse and advanced European Research Infrastructures for solid Earth science, and build on new e-science opportunities to monitor and understand the dynamic and complex solid-Earth System. One of the EPOS Thematic Core Services (TCS), referred to as Satellite Data, aims at developing, implementing and deploying advanced satellite data products and services, mainly based on Copernicus data (namely Sentinel acquisitions), for the Earth science community. This work intends to present the technological enhancements, fostered by EPOS, to deploy effective satellite services in a harmonized and integrated way. In particular, the Satellite Data TCS will deploy five services, EPOSAR, GDM, COMET, 3D-Def and MOD, which are mainly based on the exploitation of SAR data acquired by the Sentinel-1 constellation and designed to provide information on Earth surface displacements. In particular, the planned services will provide both advanced DInSAR products (deformation maps, velocity maps, deformation time series) and value-added measurements (source model

    EMSO (European Multidisciplinary Seafloor and water-column Observatory, http://www.emso-eu.org) and EPOS (European Plate Observing System, https://www.epos-ip.org) are pan-European Research Infrastructures (RIs) in the ESFRI 2016 Roadmap. EMSO has recently become an ERIC (European Research Infrastructure Consortium), whilst EPOS application is in progress. Both ERICs will be hosted in Italy and the "Representing Entity" is INGV. EMSO consists of oceanic environment observation systems spanning from the Arctic through the Atlantic and Mediterranean, to the Black Sea for long-term, high-resolution, real-time monitoring of natural and man-induced processes such as hazards, climate, and marine ecosystems changes to study their evolution and interconnections. EPOS aims at creating a pan-European infrastructure for solid Earth science to support a safe and sustainable society. EPOS will enable innovative multidisciplinary research for a better understanding of Earth's physical and chemical processes controlling earthquakes, volcanic eruptions, ground instability, tsunami, and all those processes driving tectonics and Earth's surface dynamics. Following the conclusion of their Preparatory Phases the two RIs are now in their Implementation Phase still supported by the EC through the EMSODEV and EPOS-IP projects, both run by dedicated Project Management Offices at INGV with sound experience in EU projects. EMSODEV (H2020 project, 2015-2018) involves 11 partners and 9 associate partners and aims at improving the harmonization among the EMSO ERIC observation systems through the realization of EMSO Generic Instrument Modules (EGIMs), and a Data Management Platform (DMP) to implement interoperability and standardization. The DMP will provide access to data from all EMSO nodes, providing a unified, homogeneous, infrastructure-scale and user-oriented platform integrated with the increased measurement capabilities and functions provided by the EGIMs. EPOS IP (H2020 project, 2015

    An open-label, single-dose, randomized, two-period, crossover study comparing the pharmacokinetics of factor VIII activity in plasma (FVIII:C) after administration of an albumin-free presentation of moroctocog alfa (test) and moroctocog alfa manufactured using the previous technique (reference) was conducted in 30 (25 evaluable) male subjects who had severe hemophilia A (FVIII:C < 1 IU/dL). Blood samples were collected for 48 h after administration of each dose. C was assayed using a chromogenic substrate assay. The FVIII:C pharmacokinetic parameters were calculated using noncompartmental analysis. The presentations would be bioequivalent if the 90% confidence limits of the ratio of the geometric mean values of AUC inf and recovery fell within the interval of 80-125%. The bioequivalence criteria were met. A total of 10 treatment-related adverse events were observed in a total of nine subjects. All were mild and none was determined to be related to administration of study medication. © 2018 The Authors.

    This abstract presents the collaboration between the European Collaborative Data Infrastructure (EUDAT) and the pan-European infrastructure for solid Earth science (EPOS) which draws on the management of scientific data sets through a reciprocal support agreement. EUDAT is a Consortium of European Data Centers and Scientific Communities whose focus is the development and realisation of the Collaborative Data Infrastructure (CDI), a common model for managing data spanning all European research data centres and data repositories and providing an interoperable layer of common data services. The EUDAT Service Suite is a set of a) implementations of the CDI model and b) standards, developed and offered by members of the EUDAT Consortium. These EUDAT Services include a baseline of CDI-compliant interface and API services - a "CDI Gateway" - plus a number of web-based GUIs and command-line client tools. On the other hand,the EPOS initiative aims at creating a pan-European infrastructure for the solid Earth science to support a safe and sustainable society. In accordance with this scientific vision, the mission of EPOS is to integrate the diverse and advanced European Research Infrastructures for solid Earth Science relying on new e-science opportunities to monitor and unravel the dynamic and complex Earth System. EPOS will enable innovative multidisciplinary research for a better understanding of the Earth's physical and chemical processes that control earthquakes, volcanic eruptions, ground instability and tsunami as well as the processes driving tectonics and Earth's surface dynamics. Through the integration of data, models and facilities EPOS will allow the Earth Science community to make a step change in developing new concepts and tools for key answers to scientific and socio-economic questions concerning geo-hazards and geo-resources as well as Earth sciences applications to the environment and to human welfare. To achieve this integration challenge and the

    Erythropoietin (EPO) may protect the nervous system of animals against aging damage, making it a potential anti-aging drug for the nervous system. However, experimental evidence from natural aging nerve cell models is lacking, and the efficacy of EPO and underlying mechanism of this effect warrant further study. Thus, the present study used long-term cultured primary nerve cells to successfully mimic the natural aging process of nerve cells. Starting on the 11th day of culture, cells were treated with different concentrations of recombinant human erythropoietin (rhEPO). Using double immunofluorescence labeling, we found that rhEPO significantly improved the morphology of long-term cultured primary nerve cells and increased the total number of long-term cultured primary cells. However, rhEPO did not improve the ratio of nerve cells. A 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was used to measure nerve cell activity and showed that rhEPO significantly improved the activity of long-term cultured primary nerve cells. Moreover, Annexin V-fluorescein isothiocyanate (FITC)/propidium iodide (PI) double immunofluorescence labeling flow cytometry revealed that rhEPO reduced the apoptotic rate of long-term cultured primary nerve cells. Senescence-associated β-galactosidase (SA-β-gal) immunohistochemistry staining showed that rhEPO significantly reduced the aging rate of long-term cultured primary nerve cells. Immunochemistry revealed that rhEPO enhanced intracellular superoxide dismutase (SOD) activity and glutathione (GSH) abundance and reduced the intracellular malondialdehyde (MDA) level. In addition, this effect depended on the dose, was maximized at a dose of 100 U/ml and was more pronounced than that of vitamin E. In summary, this study finds that rhEPO protects long-term cultured primary nerve cells from aging in a dose-dependent manner. The mechanism of this effect may be associated with the enhancement of the intracellular anti

    Full Text Available This paper focuses on the experimental investigation of the mechanical properties of the Alfas natural building stone. Two series of uniaxial compression tests and indirect tensile tests (Brazilian tests were performed in order to determine the uniaxial compressive strength and the indirect tensile strength respectively. Different sets of cylindrical specimens and circular discs were prepared by varying their geometry in order to examine the size effect on the respective strength values. Also, the size effect was investigated with respect to the calculated intact rock modulus and Poisson’s ratio. All specimens were prepared by following the ISRM suggested methods and the load was applied using a stiff 1600 kN MTS hydraulic testing machine and a 500 kN load cell. Strain was measured using biaxial 0/90 stacked rosettes appropriately attached on each specimen.

    Full Text Available Erythropoietin (EPO and its cell surface receptor (EPOR are essential for erythropoiesis; can modulate non-erythroid target tissues; and have been reported to affect the progression of certain cancers. Basic studies of EPOR expression and trafficking, however, have been hindered by low-level EPOR occurrence, and the limited specificity of anti-EPOR antibodies. Consequently, these aspects of EPOR biology are not well defined, nor are actions of polycythemia- associated mutated EPOR alleles. Using novel rabbit monoclonal antibodies to intracellular, PY- activated and extracellular EPOR domains, the following properties of the endogenous hEPOR in erythroid progenitors first are unambiguously defined. 1 High- Mr EPOR forms become obviously expressed only when EPO is limited. 2 EPOR-68K plus -70K species sequentially accumulate, and EPOR-70K comprises an apparent cell surface EPOR population. 3 Brefeldin A, N-glycanase and associated analyses point to EPOR-68K as a core-glycosylated intracellular EPOR pool (of modest size. 4 In contrast to recent reports, EPOR inward trafficking is shown (in UT7epo cells, and primary proerythroblasts to be sharply ligand-dependent. Beyond this, when C-terminal truncated hEPOR-T mutant alleles as harbored by polycythemia patients are co-expressed with the wild-type EPOR in EPO-dependent erythroid progenitors, several specific events become altered. First, EPOR-T alleles are persistently activated upon EPO- challenge, yet are also subject to apparent turn-over (to low-Mr EPOR products. Furthermore, during exponential cell growth EPOR-T species become both over-represented, and hyper-activated. Interestingly, EPOR-T expression also results in an EPO dose-dependent loss of endogenous wild-type EPOR's (and, therefore, a squelching of EPOR C-terminal- mediated negative feedback effects. New knowledge concerning regulated EPOR expression and trafficking therefore is provided, together with new insight into mechanisms via

    The "European Plate Observing System - Implementation Phase" (EPOS IP, 2014-2019) project is about building a pan-European infrastructure for accessing solid Earth science data. This ambitious plan started in 2002 already with a Conception Phase and continued by an EPOS PP (Preparatory Phase, 2010-2014) where about 20 partners joined the project. The current EPOS IP project includes 47 partners plus 6 associate partners from 25 countries from all over Europe and several international organizations (ORFEUS, EMSC, EUREF). However, the community contributing to the EPOS integration plan is larger than the official partnership of EPOS IP project, because more countries are represented by the international organizations and because within each country there are several research institutions involved. The list of Data, Data Products, Services and Software (DDSS) provided by individual institutions, consortia or organizations which will become part of the EPOS system are currently collected in document called DDSS Master Table. There are 10 work packages (WP8-WP17) creating the Thematic Core Services (TCS) always grouped by a specific topic: Seismology, Near Fault Observatories, GNSS Data and Products, Volcano Observations, Satellite Data, Geomagnetic Observations, Anthropogenic Hazards, Geological Information and Modelling, Multi-scale laboratories and Geo-Energy Test Beds for Low Carbon Energy. Each of this group declared a list of DDSS elements which are about to be implemented. Currently there are about 455 DDSS elements in the DDSS Master Table. These DDSS elements are of different maturity and about 122 are declared by TCS groups to be ready for implementation which means that the data are well described with metadata, following the standards specific for their domain and, in the best case, with some services allowing their access already. The DDSS elements differ by its complexity as well. The DDSS Master Table serves as an overview of the DDSS elements and

    Recent work has exploited pulsar survey data to identify temporally isolated, millisecond-duration radio bursts with large dispersion measures (DMs). These bursts have been interpreted as arising from a population of extragalactic sources, in which case they would provide unprecedented opportunities for probing the intergalactic medium; they may also be linked to new source classes. Until now, however, all so-called fast radio bursts (FRBs) have been detected with the Parkes radio telescope and its 13-beam receiver, casting some concern about the astrophysical nature of these signals. Here we present FRB 121102, the first FRB discovery from a geographic location other than Parkes. FRB 121102 was found in the Galactic anti-center region in the 1.4 GHz Pulsar Arecibo L-band Feed Array (ALFA) survey with the Arecibo Observatory with a DM = 557.4 ± 2.0 pc cm –3 , pulse width of 3.0 ± 0.5 ms, and no evidence of interstellar scattering. The observed delay of the signal arrival time with frequency agrees precisely with the expectation of dispersion through an ionized medium. Despite its low Galactic latitude (b = –0.°2), the burst has three times the maximum Galactic DM expected along this particular line of sight, suggesting an extragalactic origin. A peculiar aspect of the signal is an inverted spectrum; we interpret this as a consequence of being detected in a sidelobe of the ALFA receiver. FRB 121102's brightness, duration, and the inferred event rate are all consistent with the properties of the previously detected Parkes bursts.

    The American Astronomical Society, with organizations active in EPO, has launched professional-development workshops and a community of practice to help improve early-career astronomers' ability to communicate effectively. Called “Astronomy Ambassadors,” the program provides mentoring and training for participants, from advanced undergraduates to beginning faculty. By learning to implement effective EPO strategies, Ambassadors become better teachers, meeting presenters, and representatives of our science to the public and government. Because young astronomers are a more diverse group than those who now do most outreach, they help the astronomy community present a more multicultural and gender-balanced face to the public, enabling underserved groups to see themselves as scientists. Ambassadors are given a library of outreach activities and materials, including many developed by cooperating organizations such as the ASP, plus some that have been created by Andrew Fraknoi specifically for this program.

    Spinal cord injury is a rare disease with an incidence about 40 cases per million population in the USA. The most common reasons are traffic accidents, falls, violence and sports. A 53-year-old male patient presented with an incomplete tetraparesis as a result of a spinal cord injury after the accident. It was not possible to treat him with steroids because he was out of the therapeutic time period of 8 hours when he presented to the hospital. The main problem of spinal cord injuries is the secondary injury caused by inflammation and swelling of the spinal cord. To avoid this, the patient was experimentally treated with erythropoietin (EPO) intrathecal and EPO, granulocyte-colony-stimulating factor and vitamin C subcutaneous after his initial spinal cord relief surgery. These drugs might be able to relieve this secondary reaction but were never applied for this indication in human before. This study shows that it could be a promising treatment for spinal cord injuries with potential therapeutic benefits.

    The Astronomy Camp for Girl Scout Leaders is an education and public outreach (E/PO) program offered by the science team of the Near-InfraRed Camera (NIRCam) for NASA's 6.5-meter James Webb Space Telescope (JWST). Since 2003, astronomy graduate students have helped design and lead biannual "Train the Trainer” workshops for adults from the Girl Scouts of the USA (GSUSA), engaging these trainers in the process of scientific inquiry and equipping them to host astronomy-related activities at the troop level. These workshops have helped revise the national GSUSA badge curriculum and directly benefitted thousands of young girls of all ages, not only in general science and math education but also in specific astronomical and technological concepts relating to JWST. To date, nine graduate students have become members of NIRCam's E/PO team. They have developed curriculum and activities used to teach concepts in stellar nucleosynthesis, lookback time, galaxy classification, etc. They have also contributed to the overall strategic approach and helped lead more general activities in basic astronomy (night sky, phases of the Moon, the scale of the Solar System and beyond, stars, galaxies, telescopes, etc.) as well as JWST-specific research areas in extrasolar planetary systems and cosmology, to pave the way for girls and women to understand the first images from JWST. The resulting experience has empowered these students to propose and to develop their own E/PO programs after graduation as postdocs and young faculty. They also continue as part of NIRCam's growing worldwide network of 160 trainers teaching young women essential STEM-related concepts using astronomy, the night sky environment, applied math, engineering, and critical thinking. NIRCam and its E/PO program are funded by NASA under contract NAS5-02105.

    The Solar Dynamics Observatory (SDO) Education and Public Outreach (E/PO) program began as a series of discrete efforts implemented by each of the instrument teams and has evolved into a well-rounded program with a full suite of national and international programs. The SDO E/PO team has put forth much effort in the past few years to increase our cohesiveness by adopting common goals and increasing the amount of overlap between our programs. In this paper, we outline the context and overall philosophy for our combined programs, present a brief overview of all SDO E/PO programs along with more detailed highlight of a few key programs, followed by a review of our results up to date. Concluding is a summary of the successes, failures, and lessons learned that future missions can use as a guide, while further incorporating their own content to enhance the public's knowledge and appreciation of NASA?s science and technology as well as its benefit to society.

    A composite micelle of ionic complex encapsulated into poly(ethylene glycol)-poly(d,l-lactide) (PEG-PLA) di-block copolymeric micelles was used for protein drug delivery to improve its pharmacokinetic performance. In this study, recombinant human erythropoietin (rhEPO, as a model protein) was formulated with lysine into composite micelles at a diameter of 71.5 nm with narrow polydispersity indices (PDIs < 0.3). Only a trace amount of protein was in aggregate form. The zeta potential of the spherical micelles was ranging from -0.54 to 1.39 mv, and encapsulation efficiency is high (80 %). The stability of rhEPO was improved significantly in composite micelles in vitro. Pharmacokinetic studies in rats showed significant, enhanced plasma retention of the composite micelles in comparison with native rhEPO. Areas under curve (AUCs) of the rhEPO released from the composite micelles were 4.5- and 2.3-folds higher than those of the native rhEPO and rhEPO-loaded PEG-PLA micelle, respectively. In addition, the composite micelles exhibited good biocompatibility using MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay with human embryonic kidney (HEK293T) cells. All these features are preferable for utilizing the composite micelles as a novel protein delivery system.

    Full Text Available Erythropoietin (Epo and vascular growth factor (VEGF are known to be involved in the regulation of cellular activity when oxygen transport is reduced as in anaemia or hypoxic conditions. Because it has been suggested that Epo could play a role in skeletal muscle development, regeneration, and angiogenesis, we aimed to assess Epo deficiency in both normoxia and hypoxia by using an Epo-deficient transgenic mouse model (Epo-TAgh. Histoimmunology, ELISA and real time RT-PCR did not show any muscle fiber atrophy or accumulation of active HIF-1 but an improvement of microvessel network and an upregulation of VEGFR2 mRNA in Epo-deficient gastrocnemius compared with Wild-Type one. In hypoxia, both models exhibit an upregulation of VEGF120 and VEGFR2 mRNA but no accumulation of Epo protein. EpoR mRNA is not up-regulated in both Epo-deficient and hypoxic gastrocnemius. These results suggest that muscle deconditioning observed in patients suffering from renal failure is not due to Epo deficiency.

    EPOS Thematic Core Service ANTHROPOGENIC HAZARDS (TCS AH) aims to create new research opportunities in the field of anthropogenic hazards evoked by exploitation of georesources. TCS AH, based on the prototype built in the framework of the IS-EPOS project (https://tcs.ah-epos.eu/), financed from Polish structural funds (POIG.02.03.00-14-090/13-00), is being further developed within EPOS IP project (H2020-INFRADEV-1-2015-1, INFRADEV-3-2015). TCS AH is designed as a functional e-research environment to ensure a researcher the maximum possible freedom for in silico experimentation by providing a virtual laboratory in which researcher will be able to create own workspace with own processing streams. The unique integrated RI is: (i) data gathered in the so- called "episodes", comprehensively describing a geophysical process, induced or triggered by human technological activity, which under certain circumstances can become hazardous for people, infrastructure and the environment and (ii) problem-oriented, specific high-level services, with the particular attention devoted to methods analyzing correlations between technology, geophysical response and resulting hazard. Services to be implemented are grouped within six blocks: (1) Basic services for data integration and handling; (2) Services for physical models of stress/strain changes over time and space as driven by geo-resource production; (3) Services for analysing geophysical signals; (4) Services to extract the relation between technological operations and observed induced seismic/deformation; (5) Services to quantitative probabilistic assessments of anthropogenic seismic hazard - statistical properties of anthropogenic seismic series and their dependence on time-varying anthropogenesis; ground motion prediction equations; stationary and time-dependent probabilistic seismic hazard estimates, related to time-changeable technological factors inducing the seismic process; (6) Simulator for Multi

    2009-01-01

    In order to determine the experimental cross sections for the observed physics processes, an estimation of the absolute luminosity is needed. In fact a careful study of “well known” processes will be one of the first steps of the LHC experiments as it can provide possible signatures of new physics which consist in deviations with respect to the Standard Model (SM) predictions. The methodologies for luminosity monitoring and total cross section estimation at the LHC will be reviewed in this talk along with the dedicated detectors of the ATLAS experiment. ATLAS will make extensive usage of the detectors in the forward region each one with a different task: LUCID (LUminosity measurement using Cherenkov Integrating Detector) is a system of 40 (2 x 20) Cherenkov tubes, surrounding the beam pipe at about 17 m from the interaction region. It will be able to monitor the collision-by-collision luminosity by detecting and counting the number of charged particles coming from the impact point. ALFA (Absolute Luminosi...

  3. PI3 kinase is important for Ras, MEK and Erk activation of Epo-stimulated human erythroid progenitors

    Directory of Open Access Journals (Sweden)

    Schmidt Enrico K

    2004-05-01

    Full Text Available Abstract Background Erythropoietin is a multifunctional cytokine which regulates the number of erythrocytes circulating in mammalian blood. This is crucial in order to maintain an appropriate oxygen supply throughout the body. Stimulation of primary human erythroid progenitors (PEPs with erythropoietin (Epo leads to the activation of the mitogenic kinases (MEKs and Erks. How this is accomplished mechanistically remained unclear. Results Biochemical studies with human cord blood-derived PEPs now show that Ras and the class Ib enzyme of the phosphatidylinositol-3 kinase (PI3K family, PI3K gamma, are activated in response to minimal Epo concentrations. Surprisingly, three structurally different PI3K inhibitors block Ras, MEK and Erk activation in PEPs by Epo. Furthermore, Erk activation in PEPs is insensitive to the inhibition of Raf kinases but suppressed upon PKC inhibition. In contrast, Erk activation induced by stem cell factor, which activates c-Kit in the same cells, is sensitive to Raf inhibition and insensitive to PI3K and PKC inhibitors. Conclusions These unexpected findings contrast with previous results in human primary cells using Epo at supraphysiological concentrations and open new doors to eventually understanding how low Epo concentrations mediate the moderate proliferation of erythroid progenitors under homeostatic blood oxygen levels. They indicate that the basal activation of MEKs and Erks in PEPs by minimal concentrations of Epo does not occur through the classical cascade Shc/Grb2/Sos/Ras/Raf/MEK/Erk. Instead, MEKs and Erks are signal mediators of PI3K, probably the recently described PI3K gamma, through a Raf-independent signaling pathway which requires PKC activity. It is likely that higher concentrations of Epo that are induced by hypoxia, for example, following blood loss, lead to additional mitogenic signals which greatly accelerate erythroid progenitor proliferation.

    The current European Pharmacopoeia (Ph. Eur.) texts for Interferon (IFN)-alfa-2 include a nonspecific photometric protein assay using albumin as calibrator and a highly variable cell-based assay for the potency determination of the protective effects. A request was expressed by the Official Medicines Control Laboratories (OMCLs) for improved methods for the batch control of recombinant interferon alfa-2 bulk and market surveillance testing of finished products, including those formulated with Human Serum Albumin (HSA). A HPLC method was developed at the Medical Products Agency (MPA, Sweden) for the testing of IFN-alfa-2 products. An initial collaborative study run under the Biological Standardisation Programme (BSP; study code BSP039) revealed the need for minor changes to improve linearity of the calibration curves, assay reproducibility and robustness. The goal of the collaborative study, coded BSP071, was to transfer and further validate this improved HPLC method. Ten laboratories participated in the study. Four marketed IFN-alfa-2 preparations (one containing HSA) together with the Ph. Eur. Chemical Reference Substance (CRS) for IFN-alfa-2a and IFN-alfa-2b, and in-house reference standards from two manufacturers were used for the quantitative assay. The modified method was successfully transferred to all laboratories despite local variation in equipment. The resolution between the main and the oxidised forms of IFN-alfa-2 was improved compared to the results from the BSP039 study. The improved method even allowed partial resolution of an extra peak after the principal peak. Symmetry of the main IFN peak was acceptable for all samples in all laboratories. Calibration curves established with the Ph. Eur. IFN-alfa-2a and IFN-alfa-2b CRSs showed excellent linearity with intercepts close to the origin and coefficients of determination greater than 0.9995. Assay repeatability, intermediate precision and reproducibility varied with the tested sample within acceptable

    Recombinant human erythropoietin (rHuEpo) can improve human performance and is therefore frequently abused by athletes. As a result, the World Anti-Doping Agency (WADA) introduced the Athlete Biological Passport (ABP) as an indirect method to detect blood doping. Despite this progress, challenges remain to detect blood manipulations such as the use of microdoses of rHuEpo. Forty-five whole-blood transcriptional markers of rHuEpo previously derived from a high-dose rHuEpo administration trial were used to assess whether microdoses of rHuEpo could be detected in 14 trained subjects and whether these markers may be confounded by exercise (n = 14 trained subjects) and altitude training (n = 21 elite runners and n = 4 elite rowers, respectively). Differential gene expression analysis was carried out following normalisation and significance declared following application of a 5% false discovery rate (FDR) and a 1.5 fold-change. Adaptive model analysis was also applied to incorporate these markers for the detection of rHuEpo. ALAS2, BCL2L1, DCAF12, EPB42, GMPR, SELENBP1, SLC4A1, TMOD1 and TRIM58 were differentially expressed during and throughout the post phase of microdose rHuEpo administration. The CD247 and TRIM58 genes were significantly up- and down-regulated, respectively, immediately following exercise when compared with the baseline both before and after rHuEpo/placebo. No significant gene expression changes were found 30 min after exercise in either rHuEpo or placebo groups. ALAS2, BCL2L1, DCAF12, SLC4A1, TMOD1 and TRIM58 tended to be significantly expressed in the elite runners ten days after arriving at altitude and one week after returning from altitude (FDR > 0.059, fold-change varying from 1.39 to 1.63). Following application of the adaptive model, 15 genes showed a high sensitivity (≥ 93%) and specificity (≥ 71%), with BCL2L1 and CSDA having the highest sensitivity (93%) and specificity (93%). Current results provide further evidence that

    Hopkinsville, Kentucky was the largest town in the region of maximum totality for the 21 August 2017 Solar Eclipse, and transformed itself into “Eclipseville” with extensive media attention. Here we give 2 on-the-ground reports on education and public outreach (E/PO) activities from Hopkinsville. One of us (TD) partnered with the Kentucky Division of Emergency Management (KYEM) and was in the Hopkinsville VIP area, and the other (GC) led a series of E/PO events at the Hopkinsville Church of Ss. Peter & Paul, which were nationally advertised in diocesan newspapers. In addition, both of us were interviewed extensively by local and national media before the event. Pre-event planning by KYEM extended for over a year, and culminated in a 6-hour, 12 July 2017 Tabletop Exercise (TTX) run by FEMA. This face-to-face workshop drew over 250 participants, including Kentucky’s Lt. Governor, health and public safety officials at the state-level and from the 21 Kentucky counties in the path of totality, mayors and convention-bureau officials from the affected KY towns, the KY National Guard, the U.S. Depts. of Health and Human Services, Homeland Security, and Transportation, the National Weather Service, the U.S. Coast Guard for riverboat traffic, the U.S. Forest Service, the American Red Cross, representatives from ATT, Verizon and Sprint, and representatives from local universities—it was the largest TTX in Kentucky’s history. Here, we report on E/PO feedback we assembled from the VIP and parochial sites, including the most frequently asked questions, which types of answers seemed to be most effective, and how actual events compared with the large-crowd preparations and planning.

Il a utilise la micro-autoradiographie a l'aide de thymidine tritiee pour determiner la vitesse de synthese dans des cultures en couche unique. Les experiences ont montre que: 1. Le nombre des cellules synthetisant l'ADN n'est pas influence par les particules ac et les rayons X, pour les doses utilisees pendant l'experience. 2. Les deux types de rayonnements ont pour effet de reduire la vitesse de synthese de l'ADN dans les cellules irradiees. 3. Une dose determinee de l'un des deux types de rayonnements a pour effet de ramener la vitesse de synthese dans toutes les cellules a une fraction constante de la vitesse observee pour les cellules non irradiees. 4. La vitesse de synthese de l'ADN est reduite a 37% de sa valeur initiale a 37% (1/e) par une dose d'environ 25 {alpha}/p{sup 2} ou par une dose de rayons X de 14 000 rad pour les cultures de fibroblastes de souris. Pour les cultures de cellules HeLa, il faut une dose d'environ 90 000 rads pour reduire la vitesse de synthese de l'ADN a 37% de sa valeur initiale. 5. Le ralentissement de la synthese se manifeste au plus tard une demi-heure apres l'irradiation ; il peut etre immediat. Les indications donnees au point 4 ci-dessus permettent de calculer approximativement la forme de la cible; si l'on admeto qu'elle est cylindrique, elle semble avoir pour dimensions environ 16 A dans un sens et 16 000 A dans l'autre; c'est donc un long filament mince, d'un poids moleculaire d'environ 5 * 10{sup 7}, dans les experiences faites sur les fibroblastes de souris. Dans les experiences faites sur les cellules HeLa, le volume des cibles donne un poids moleculaire de 10{sup 7} environ. Les resultats concordent avec l'opinion selon laquelle la cible pourrait etre la structure type de l'ADN (ou eventuellement de la molecule de nucleoproteine etant donne le poids moleculaire eleve dans l'un des deux cas).

We hypothesize that therapy with dornase alfa will be safe and well tolerated in the preterm population with no worsening of symptoms, oxygen requirement, or need for respiratory support. Prospective, randomized, blinded, pilot study comparing adjunctive treatment with dornase alfa to sham therapy. In addition to standard care, infants were randomized to receive dornase alfa 2.5 mg nebulized via endotracheal tube (ETT) every 12 hr for 7 days or sham therapy. ETT secretion gram stain and culture and chest X-ray (CXR) findings were evaluated. Respiratory support data were downloaded from the ventilator. Fourteen infants developed VAPI between 2012 and 2014; 11 enrolled in the study. Six received dornase alfa and five received sham therapy. Average gestational age at birth was 25 weeks and age at study entry was 31 days. There were no differences in demographics, ETT white blood cell count (WBC), CXR, or mean airway pressure (MAP) between the two groups. There was a trend towards decreased oxygen requirement (FiO2) in the treatment group that did not reach statistical significance. No side effects were observed in the treatment group. Treatment with dornase alfa is safe and treated infants had some improvement in FiO 2 requirement but no improvement in MAP. A larger randomized trial is needed to evaluate the efficacy of this therapy. Pediatr Pulmonol. 2017; 52:787-791. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

    One of the goals of procurement is to establish a competitive price, while e-procurement utilises electronic commerce to identify potential sources of supply, to purchase goods and services, to exchange contractual information and to interact with suppliers. Extensive academic work has been extensively devoted to e-procurement in diverse industries. However, applying e-procurement in the healthcare sector remains unexplored. It lacks an efficient e-procurement mechanism that will enable hospitals and healthcare suppliers to electronically exchange contractual information, aided by the technologies of optimisation and business rules. The development and deployment of e-procurement requires a major effort in the coordination of complex interorganisational business process. This article presents an e-procurement optimised system (EPOS) for the healthcare marketplace, a complete methodological approach for deploying and operating such system, as piloted in public and private hospitals in three European countries (Greece, Spain and Belgium) and suppliers of healthcare items in the fourth country (Italy). The efficient e-procurement mechanism that EPOS suggests enables hospitals and pharmaceutical and medical equipment suppliers to electronically exchange contractual information.

Although erythropoietin (EPO has a protective role in a wide range of organs and cells during ischemia and after trauma, it has been recently discovered that EPO is not tissue-protective in the common β subunit receptor (βCR knockout mouse. The protective capacity of EPO in tissue is mediated via a heteroreceptor complex comprising both the erythropoietin receptor (EPOR and βCR. However, proof of coexpression of these heterogenic receptors in regenerating skin after burns is still lacking.Methods: To understand the role of nanosized recombinant human erythropoietin (rhEPO in wound healing, we investigated the effects of subcutaneous injections of EPO on skin regeneration after deep second-degree scalding injuries. Our aim was to determine if joint expression of EPOR and βCR is a prerequisite for the tissue-protective effect of rhEPO. The efficiency in wound regeneration in a skin scalding injury mouse model was examined. A deep second-degree dermal scald injury was produced on the backs of 20 female Balb/c mice which were subsequently randomized to four experimental groups, two of which received daily subcutaneous injections of rhEPO. At days 7 and 14, the mice were sacrificed and the effects of rhEPO were

    Women are outnumbered by men in geosciences senior research positions, but what is the situation if we consider large pan-European Research Infrastructures? With this contribution we want to show an analysis of the role of women in the implementation of the European Plate Observing System (EPOS): a planned research infrastructure for European Solid Earth sciences, integrating national and transnational research infrastructures to enable innovative multidisciplinary research. EPOS involves 256 national research infrastructures, 47 partners (universities and research institutes) from 25 European countries and 4 international organizations. The EPOS integrated platform demands significant coordination between diverse solid Earth disciplinary communities, national research infrastructures and the policies and initiatives they drive, geoscientists and information technologists. The EPOS architecture takes into account governance, legal, financial and technical issues and is designed so that the enterprise works as a single, but distributed, sustainable research infrastructure. A solid management structure is vital for the successful implementation and sustainability of EPOS. The internal organization relies on community-specific Working Packages (WPs), Transversal WPs in charge of the overall EPOS integration and implementation, several governing, executive and advisory bodies, a Project Management Office (PMO) and the Project Coordinator. Driven by the timely debate on gender balance and commitment of the European Commission to promote gender equality in research and innovation, we decided to conduct a mapping exercise on a project that crosses European national borders and that brings together diverse geoscience disciplines under one management structure. We present an analysis of women representation in decision-making positions in each EPOS Working Package (WP Leader, proxy, legal, financial and IT contact persons), in the Boards and Councils and in the PMO

    The mission of EPOS is to monitor and understand the dynamic and complex Earth system by relying on new e-science opportunities and integrating diverse and advanced Research Infrastructures in Europe for solid Earth Science. EPOS will enable innovative multidisciplinary research for a better understanding of the Earth's physical and chemical processes that control earthquakes, volcanic eruptions, ground instability and tsunami as well as the processes driving tectonics and Earth's surface dynamics. Through integration of data, models and facilities EPOS will allow the Earth Science community to make a step change in developing new concepts and tools for key answers to scientific and socio-economic questions concerning geo-hazards and geo-resources as well as Earth sciences applications to the environment and to human welfare. EPOS, during its Implementation Phase (EPOS-IP), will integrate multidisciplinary data into a single e-infrastructure. Multidisciplinary data are organized and governed by the Thematic Core Services (TCS) and are driven by various scientific communities encompassing a wide spectrum of Earth science disciplines. These include Data, Data-products, Services and Software (DDSS), from seismology, near fault observatories, geodetic observations, volcano observations, satellite observations, geomagnetic observations, as well as data from various anthropogenic hazard episodes, geological information and modelling. In addition, transnational access to multi-scale laboratories and geo-energy test-beds for low-carbon energy will be provided. TCS DDSS will be integrated into Integrated Core Services (ICS), a platform that will ensure their interoperability and access to these services by the scientific community as well as other users within the society. This requires dedicated tasks for interactions with the various TCS-WPs, as well as the various distributed ICS (ICS-Ds), such as High Performance Computing (HPC) facilities, large scale data storage

    TCS AH is based on IS-EPOS Platform. The Platform facilitates research on anthropogenic hazards and is available online, free of charge https://tcs.ah-epos.eu/. The Platform is a final product of the IS-EPOS project, founded by the national programme - POIG - which was implemented in 2013-2015 (POIG.02.03.00-14-090/13-00). The platform is a result of a joint work of scientific community and industrial partners. Currently, the development of TCS AH is carried under EPOS IP project (H2020-INFRADEV-1-2015-1, INFRADEV-3-2015). Platform is an open virtual access point for researchers and Ph. D. students interested in anthropogenic seismicity and related hazards. This environment is designed to ensure a researcher the maximum possible liberty for experimentation by providing a virtual laboratory, in which the researcher can design own processing streams and process the data integrated on the platform. TCS AH integrates: data and specific high-level services. Data gathered in the so-called "episodes", comprehensively describing a geophysical process, induced or triggered by human technological activity, which, under certain circumstances can become hazardous for people, infrastructure and the environment. 7 sets of seismic, geological and technological data were made available on the Platform. The data come from Poland, Germany, UK and Vietnam, and refer to underground mining, reservoir impoundment, shale gas exploitation and geothermal energy production. The next at least 19 new episodes related to conventional hydrocarbon extraction, reservoir treatment, underground mining and geothermal energy production are being integrated within the framework of EPOS IP project. The heterogeneous multi-disciplinary data (seismic, displacement, geomechanical data, production data etc.) are transformed to unified structures to form integrated and validated datasets. To deal with this various data the problem-oriented services were designed and implemented. The particular attention

    The European Plate Observing System project is currently approaching the end of year two of its four-year Implementation Phase 2015-18 (EPOS-IP). Under the Horizon 2020 Programme INFRADEV-3, the EPOS cyberinfrastructure is being established as an ERIC (European Research Infrastructure Consortium) and encompasses the implementation of both the EPOS Integrated Core Services (ICS) for solid Earth Science and a multitude of EPOS Thematic Core Services (TCS). During year two, a basic set of ICS and TCS services was developed and implemented, so that in October 2017 the validation phase (year 3) of EPOS is ready to be launched. Up to now, various TCS-Elements have integrated different Service Providers (SD) that are delivering Data, Data Products, Services and Software (DDSS) to their specific scientific community. As one of the 29 awardees of the EC grant, the German Research Center for Geosciences (GFZ) plays an important role in the implementation of EPOS and its Thematic and Integrated Core Services. The presented poster will give an overview of GFZ's participation in the work of nine technical EPOS Work Packages (WP7 ICS Development, WP8 Seismology, WP11 Volcano Observations, WP12 Satellite Data, WP13 Geomagnetic Observations, WP14 Anthropogenic Hazards, WP15 Geological Information and Modelling, WP16 Multi-Scale Laboratories and WP17 Geo Energy Test Beds) as well as in four administrative EPOS Work Packages (WP2 Communication, WP3 Harmonization, WP4 Legal & Governance, and WP5 Financial).

    Full text: Tumor hypoxia, particularly in anemia, increases the risk of distant metastases and decreases survival. However, the benefits of stimulating erythropoiesis to supraphysiological levels are unclear. This study examines the effect of darbepoetin alfa (DEPA) on tumor oxygenation and the response to therapeutic radiation (XRT) in rats with initially normal hematocrit. R3230 adenocarcinoma was transplanted into the flank of female Fisher 344 rats. Starting on Day 4 post transplant, the rats received DEPA 3 μg/kg or normal saline sc tiw. At 3 weeks post transplant, pO2 was measured and the tumor excised, or the tumor was irradiated. pO2 was determined using an optical microprobe. In histologic studies, rats were injected with pimonidazole prior to sacrifice, and the tumors excised and stained with an antibody to pimonidazole (PIMO). Extent/intensity of staining was assessed by 3 observers and averaged to yield an IHC score. Rats ± DEPA with tumors 7 -12mm diameter were randomised to receive 32 Gy in 4 bid doses or sham irradiation. Tumor diameters in the 4 groups (±DEPA x ±XRT, total n=41) were measured by calipers. Failure was defined by the tumor reaching 15mm in diameter and used to generate Kaplan-Meier curves. Hematocrit at transplant averaged 45% (n=104) versus 67% in the DEPA-treated rats (n=18, p<0.0001) and 44% in the control animals (n=21.) Median pO2 in the DEPA-treated rats vs. controls did not differ significantly (17 vs. 13 mm Hg, p=0.10.) However, the fraction of tumor pO2 measurements <10mm Hg in the DEPA-treated rats was lower (21% vs. 37%, p=0.046.) IHC score was also less in the DEPA group (p=0.03.) XRT significantly improved failure-free survival (p<0.0001.) While the addition of DEPA to either the XRT or control groups did not significantly increase survival, the trend in both cases favored the DEPA-treated groups. In this tumor, treatment with DEPA improves oxygenation. However, no significant enhancement in radioesponsiveness by DEPA

    Erythropoietin (EPO) is a cytokine known to have effective cytoprotective action in the brain, particularly in ischemic, traumatic, inflammatory, and neurodegenerative conditions. We previously reported the neuroprotective effect of a low sialic form of EPO, Neuro-EPO, applied intranasally in rodent models of stroke or cerebellar ataxia and in a non-transgenic mouse model of Alzheimer's disease (AD). Here we analyzed the protective effect of Neuro-EPO in APPSwe mice, a reference transgenic mouse model of AD. Mice were administered 3 times a day, 3 days in the week with Neuro-EPO (125, 250 μg/kg) intranasally, between 12 and 14 months of age. Motor responses, general activity, and memory responses were analyzed during and after treatment. The deficits in spontaneous alternation, place learning in the water-maze, and novel object recognition observed in APPSwe mice were alleviated by the low dose of Neuro-EPO. Oxidative stress, neuroinflammation, trophic factor levels, and a synaptic marker were analyzed in the hippocampus or cortex of the animals. The increases in lipid peroxidation or in GFAP and Iba-1 contents in APPSwe mice were significantly reduced after Neuro-EPO. Activation of intrinsic and extrinsic apoptotic pathways was analyzed. The increases in Bax/Bcl-2 ratio, TNFα, or Fas ligand levels observed in APPSwe mice were reduced by Neuro-EPO. Finally, immunohistochemical and ELISA analyses of Aβ1-42 levels in the APPSwe mouse cortex and hippocampus showed a marked reduction in Aβ deposits and in soluble and insoluble Aβ1-42 forms. This study therefore confirmed the neuroprotective activity of EPO, particularly for an intranasally deliverable formulation, devoid of erythropoietic side effects, in a transgenic mouse model of AD. Neuro-EPO alleviated memory alterations, oxidative stress, neuroinflammation, apoptosis induction, and amyloid load in 14-month-old APPSwe mice.

    Over the past two years, the Incorporated Research Institutions for Seismology Education and Public Outreach (EPO) program has sought to increase the evaluation rigor of its programs and products. Specifically we sought to make evaluation an integral part of our work; enabling staff to demonstrate why we do the activities we do, enhancing the impact or our products/programs, and empowering staff to make evidence-based claims. The Collaborative Impact Analysis Method (Davis and Scalice, 2015) was selected as it allowed us to combine staff's knowledge of programs, audiences and content with the expertise of an outside evaluation expert, through consultations and a qualitative rubric assessing the initial state of each product/program's evaluation. Staff then developed action plans to make improvements to the programs over time. A key part of the initial action plans has been the collection and analysis of new evaluation data. The most frequently used tools were surveys as they were relatively straightforward to implement and analyze, and could be adapted for different situations. Examples include: brand awareness, value of booth interactions, assessing community interest in a data app, and user surveys of social media and specific web pages. Other evaluation activities included beta testing of new software, and interviews with students and faculty involved in summer field experiences. The surveys have allowed us to document increased impact in some areas, to improve the usability of products and activities, and to provide baseline impact data. The direct involvement of staff in the process has helped staff appreciate the value of evaluation, but there are also challenges to this approach. Since many of the surveys are developed and conducted by EPO staff, rather than being primarily handled by the evaluator, the process takes considerably more staff time to implement. We are still determining how to best manage and present the data and analysis; our current approach

    Alfa leaves are important renewable raw materials in Tunisia where they are used basically in handcrafts and paper industry. Sumac is also an abundant species in Tunisia known for its high tannin content and is basically used in traditional medicine. To valorize these natural resources, we studied, for the first time, the possibility of making insulating panels based on alfa fibres and sumac tannins based adhesive. Firstly, alfa leaves were treated with an alkali solution as it is one of the standard procedures commonly used in the paper industry to extract cellulosic fibres. Mercerization effects were studied by characterizing fibres thermal properties and fibres surface morphology. Secondly, the sumac tannin based resin was formulated and characterized. Finally, the insulating panel was elaborated and characterized by determining its thermal conductivity. The thermal gravimetric analysis results show improvement in the thermal stability of fibres after alkali treatment. Environmental Scanning Electron Microscopy showed changes on treated alfa surface which could promote the fibre-matrix adhesion. The reactivity of sumac tannins to formaldehyde test (Stiasny number) showed the possible use of sumac tannins in wood adhesive formulation. Thermomechanical analysis and strength analysis of sumac tannin/hexamin based resin highlighted acceptable bonding properties. The thermal conductivity measurement showed an average value equal to 0.110 W/m K.

    The overproduction and stagnation of purulent mucus impair mucociliary clearance and exacerbate the symptoms of chronic rhinosinusitis (CRS). There is a clinical need for effective topical mucolytic agents to facilitate removal of mucus and improve postoperative outcomes. The effects of xylitol (5%) and dornase alfa (1 mg/mL) on mucus and mucus crusts were investigated. Viscoelasticity and viscosity of wet mucus derived from 30 CRS patients was measured with a plate rheometer. Postoperative dried mucus crust dissolution was measured by examining peripheral transparency, central transparency, and border definition of treated crust samples from 17 CRS patients. Xylitol and dornase alfa reduced wet mucus viscoelasticity at a frequency of 0.1 Hz significantly more than the saline control. Treatments also produced significantly lower viscosities than saline at a shear rate of 10 and 100 seconds -1 . Xylitol and dornase alfa significantly decreased mucus crust border definition relative to saline. Xylitol and dornase alfa may be efficacious mucolytics, encouraging the breakdown of postoperative mucus crusts and the reduction of viscoelasticity and viscosity of wet mucus. In vivo study is required to evaluate the potential of these agents in treating recalcitrant CRS. © 2017 ARS-AAOA, LLC.

    2011-06-01

    The dynamic behavior of aluminum nanoparticle-fluorinated acrylic (AlFA) composite materials has been explored under high strain rates. Cylindrical pellets of the AlFA composite materials were mounted onto copper sabots and impacted against a rigid anvil at velocities between 100 and 400 m/s utilizing a Taylor gas gun apparatus to achieve strain rates on the order of 104 /s. A framing camera was used to record the compaction and reaction events that occurred upon contact of the pellet with the anvil. Under both open air and vacuum environments the AlFA composites demonstrated high reactivity suggesting that the particles are primarily reacting with the fluorinated matrix. We hypothesize, based upon the compaction history of these materials, that reaction is initiated when the oxide shells on the aluminum nanoparticles are broken due an interparticle contact deformation process. We have investigated this hypothesis through altering the particle loading in the AlFA composites as well as impact velocities. This data and the corresponding trends will be presented in detail.

There are three commercially available enzyme replacement therapy (ERT products for the treatment of GD type 1 (GD1: imiglucerase, velaglucerase alfa, and taliglucerase alfa. Imiglucerase and velaglucerase alfa are produced in different mammalian cell systems; imiglucerase requires postproduction deglycosylation to expose terminal α-mannose residues, which are required for mannose receptor-mediated uptake by target macrophages. These steps are critical to the success of ERT for the treatment of visceral and hematologic manifestations of GD. Taliglucerase alfa is the first US Food and Drug Administration-approved plant-cell-expressed recombinant human protein, using carrot root cell cultures. Furthermore, it does not require postproduction glycosidic modifications.

    EPO-018B, a synthetic peptide-based erythropoiesis stimulating agent (ESA), is mainly designed for treatment of anemia caused by chronic renal failure and chemotherapy against cancer. It overcomes the deficiencies of currently approved ESA, including the frequent administration of temperature-sensitive recombinant protein and anti-EPO antibody-mediated pure red cell aplasia (PRCA). This study was designed to evaluate the potential chronic toxicity of EPO-018B. Subcutaneous administration doses were designed as 0, 0.2, 1 and 10 mg/kg for six months for 160 rats (20/gender/group) and 0, 0.3, 3 and 20 mg/kg for nine months for 32 monkeys (4/gender/group) once every three weeks. The vehicles received the same volume of physiological saline injection. All animals survived to the scheduled necropsies after six weeks (for rats) and fourteen weeks (for monkeys) recovery period, except for the two high-dose female rats and two high-dose male monkeys, which were considered related to the increased RBCs, chronic blood hyperviscosity and chronic cardiac injury. EPO-018B is supposed to be subcutaneously injected once every month and the intended human therapeutic dose is 0.025 mg/kg. The study findings at 0.2 mg/kg for rats and 0.3 mg/kg for monkeys were considered to be the study NOAEL (the no observed adverse effect level), which were more than ten times the intended human therapeutic dose. Higher doses caused adverse effects related to the liver toxicity, cardiotoxicity, appearance of neutralizing antibodies of EPO-018B and the decrease of serum glucose and cholesterol. Most treatment-induced effects were reversible or revealed ongoing recovery upon the discontinuation of treatment. The sequelae occurred in rats and monkeys were considered secondary to exaggerated pharmacology and would less likely occur in the intended patient population. As to the differences between human beings and animals, the safety of EPO-018B need to be further confirmed in the future clinical

    2017-04-01

    EPOS, the European Plate Observing System, is an ESFRI infrastructure serving the needs of the solid Earth science community as a whole. EPOS promotes the use of multidisciplinary solid Earth data to improve the understanding of physical and chemical processes controlling earthquakes, volcanic eruptions, tsunamis as well as those driving tectonics and surface dynamics. The EPOS mission is to create a single, sustainable, and distributed infrastructure that integrates the diverse European research infrastructures for solid Earth science under a common framework with the final goal of delivering a suite of domain-specific and multidisciplinary data, products, and services in one single and integrated platform. Addressing ethics issues is a relevant challenge for any initiative, program or project dealing with scientific data and products provision, access to services for scientific purposes and communication with different stakeholders, including industry and society at large. In examining the role of EPOS on openly and freely delivering scientific data and products to diverse stakeholders including but not limited to scientists, we are looking at ethical issues associated with the use and re-use of these data and products possibly leading to a malevolent use and/or misuse of the data with implications on, for example, national security, environmental protection and risk communication. Moreover, EPOS is aware that the research promoted by the use of data delivered through its platform can have a profound influence on the environment, human health and wellbeing, economic development, and other facets of societies. We know there is nothing intrinsically bad about openly and freely delivering scientific data, as it serves as a tool for leveraging researches leading to solutions for a responsible management of Earth's resources and mitigation of natural hazards. However, we must evaluate the effects of such a data provision and feel the obligation to adopt a responsible

    Full Text Available Abstract Background Activated drotrecogin alfa (human activated protein C, rhAPC, is produced by recombinant DNA technology, and purports to improve clinical outcomes by counteracting the inflammatory and thrombotic consequences of severe sepsis. Controversy exists around the clinical benefits of this drug and an updated economic study that considers this variability is needed. Methods A systematic literature review was performed using Medline, Embase and the International Network of Agencies for Health Technology Assessment (INAHTA databases to determine efficacy, safety and previous economic studies. Our economic model was populated with systematic estimates of these parameters and with population life tables for longer term survival information. Monte Carlo simulations were used to estimate the incremental cost-effectiveness ratios (ICERs and variance for the decision analytic models. Results Two randomized clinical trials (RCTS of drotrecogin alfa in adults with severe sepsis and 8 previous economic studies were identified. Although associated with statistical heterogeneity, a pooled analysis of the RCTs did not show a statistically significant 28-day mortality benefit for drotrecogin alfa compared to placebo either for all patients (RR: 0.93, 95% CI: 0.69, 1.26 or those at highest risk as measured by APACHE II ≥ 25 (RR: 0.90, 95% CI: 0.54, 1.49. Our economic analysis based on the totality of the available clinical evidence suggests that the cost-effectiveness of drotrecogin alfa is uncertain ( Conclusion The evidence supporting the clinical and economic attractiveness of drotrecogin alfa is not conclusive and further research appears to be indicated.

    Addressing Ethics issues is nowadays a relevant challenge for any initiative, program or project dealing with scientific data and products provision, access to services for scientific purposes and communication with different stakeholders, including society. This is corroborated by the evidence that Ethics has very high priority in EU funded research. Indeed, all the activities carried out under Horizon 2020 must comply with ethical principles and national, Union and international legislation. This implies that "For all activities funded by the European Union, Ethics is an integral part of research from beginning to end, and ethical compliance is seen as pivotal to achieve real research excellence." Here, we present the experience of EPOS, a public pan-European research infrastructure. EPOS aims at integrating data, data products, services and software (DDSS) for solid Earth science generated and provided by monitoring networks, observing systems and facilities belonging to European countries. EPOS fosters the integrated use of multidisciplinary solid Earth data to improve the understanding of physical and chemical processes controlling earthquakes, volcanic eruptions, tsunamis as well as those driving tectonics and surface dynamics. The EPOS integration plan will make significant contributions to understanding and mitigating geo-hazards, yielding data for hazard assessment, data products for engaging different stakeholders, and services for training, education and communication to society. Numerous national research infrastructures engaged in EPOS are deployed for the monitoring of areas prone to geo-hazards and for the surveillance of the national territory including areas used for exploiting geo-resources. The EPOS community is therefore already trained to provide services to public (civil defence agencies, local and national authorities) and private (petroleum industry, mining industry, geothermal companies, aviation security) stakeholders.

    With continuous progress on scientific research, a large amount of datasets has been and will be produced. The data access and sharing along with their storage and homogenization within a unique and coherent framework is a new challenge for the whole scientific community. This is particularly emphasized for geo-scientific laboratories, encompassing the most diverse Earth Science disciplines and typology of data. To this aim the "Multiscale Laboratories" Work Package (WP16), operating in the framework of the European Plate Observing System (EPOS), is developing a virtual platform of geo-scientific data and services for the worldwide community of laboratories. This long-term project aims at merging the top class multidisciplinary laboratories in Geoscience into a coherent and collaborative network, facilitating the standardization of virtual access to data, data products and software. This will help our community to evolve beyond the stage in which most of data produced by the different laboratories are available only within the related scholarly publications (often as print-version only) or they remain unpublished and inaccessible on local devices. The EPOS multi-scale laboratory platform will provide the possibility to easily share and discover data by means of open access, DOI-referenced, online data publication including long-term storage, managing and curation services and to set up a cohesive community of laboratories. The WP16 is starting with three pilot cases laboratories: (1) rock physics, (2) palaeomagnetic, and (3) analogue modelling. As a proof of concept, first analogue modelling datasets have been published via GFZ Data Services (http://doidb.wdc-terra.org/search/public/ui?&sort=updated+desc&q=epos). The datasets include rock analogue material properties (e.g. friction data, rheology data, SEM imagery), as well as supplementary figures, images and movies from experiments on tectonic processes.

    2016-04-01

    Coherently with the EPOS vision aimed at creating a pan-European infrastructure for Earth Sciences supporting research for a more sustainable society, we are working on the integration of NFOs and services implementation facilitating their data and products discovery and usage. NFOs are National Research Infrastructures (NRI) consisting of advanced networks of multi-parametric sensors continuously monitoring the chemical and physical processes related to the common underlying Earth instabilities governing active faults evolution and the genesis of earthquakes. These infrastructures will enable advancements in understanding of earthquakes generation processes and associated ground shaking due to their high-quality near-source multidisciplinary data. In EPOS-IP seven NFOs are going to be linked: 1) the Altotiberina and 2) Irpinia Observatories in Italy, 3) Corinth in Greece, 4) South-Iceland Seismic Zone, 5) Valais in Switzerland, 6) Marmara Sea (GEO Supersite) in Turkey and 7) Vrancea in Romania. EPOS-IP aims to implement integrated services from a technical, legal, governance and financial point of view. Accordingly, our first effort within this first core group of NFOs will be establishing legal governance for such a young community to ensure a long-term sustainability of the envisaged services including the full adoption of the EPOS data policy. The establishment of a Board including representatives of each NFO formally appointed by the Institutions supporting the NRI is a basic requirement to provide and validate a stable governance mechanism supporting the initiatives finalised to the services provision. Extremely dense networks and less common instruments deserve an extraordinary work on data quality control and description. We will work on linking all the NFOs in a single distributed network of observatories with instrumental and monitoring standards based on common protocols for observation, analysis, and data access and distributed channels. We will rely on

    A survey of community college STEM faculty, administered by the NASA SMD Higher Education Working Group (HEWG), was administered in fall 2012 in an effort to document the demographic make-up and views of community college faculty who teach NASA science-related STEM courses in astronomy, physics, Earth science, and engineering. Nearly half of respondents reported that less than 10% of students in their classroom are “STEMward bound” and indicated the need for STEM resources that can relate science course content and be relevant to the daily life of their students. A number of respondents also noted a new or renewed emphasis on outreach activities within the community served by their institution as part of their job description. The survey suggests specific directions and ways that the NASA SMD EPO forum can support two-year college stakeholders.

    The SOFIA and SIRTF EPO Programs have partnered with the Conceptual Astronomy and Physics Education Research (CAPER) Team in designing, evaluating, and facilitating an online program for K-12 teachers to experience multiwavelength astronomy. An aggressive approach to online course design and delivery has resulted in a highly successful learning experience for teacher-participants. Important aspects of the Invisible Universe Online will eventually be used as a part of SOFIA's Airborne Ambassadors Program for pre-flight training of educators. The Invisible Universe Online is delivered via WebCT through the Montana State University National Teacher Enhancement Network (http://btc.montana.edu/). Currently in its fourth semester, the course has served 115 K-12 teachers. This distance learning online class presents our search for astronomical origins and provides an enhanced understanding of how astronomers use all energies of light to unfold the secrets of the universe. We cover the long chain of events from the birth of the universe through the formation of galaxies, stars, and planets by focusing on the scientific questions, technological challenges, and space missions pursuing this search for origins. Through textbook and internet readings, inquiry exploration with interactive java applets, and asynchronous discussions, we help our students achieve the following course goals: develop scientific background knowledge of astronomical objects and phenomena at multiple wavelengths; understand contemporary scientific research questions related to how galaxies formed in the early universe and how stars and planetary systems form and evolve; describe strategies and technologies for using non-visible wavelengths of EM radiation to study various phenomena; and integrate related issues of astronomical science and technology into K-12 classrooms. This course is being developed, evaluated, and offered through the support of SOFIA and SIRTF EPO Programs, two NASA infrared missions

    2014-12-01

    For the 2009 International Year of Astronomy, the then-existing NASA Origins Forum collaborated with the Astronomical Society of the Pacific (ASP) to create a series of monthly "Discovery Guides" for informal educator and amateur astronomer use in educating the public about featured sky objects and associated NASA science themes. Today's NASA Astrophysics Science Education and Public Outreach Forum (SEPOF), one of a new generation of forums coordinating the work of NASA Science Mission Directorate (SMD) EPO efforts—in collaboration with the ASP and NASA SMD missions and programs--has adapted the Discovery Guides into "evergreen" educational resources suitable for a variety of audiences. The Guides focus on "deep sky" objects and astrophysics themes (stars and stellar evolution, galaxies and the universe, and exoplanets), showcasing EPO resources from more than 30 NASA astrophysics missions and programs in a coordinated and cohesive "big picture" approach across the electromagnetic spectrum, grounded in best practices to best serve the needs of the target audiences. Each monthly guide features a theme and a representative object well-placed for viewing, with an accompanying interpretive story, finding charts, strategies for conveying the topics, and complementary supporting NASA-approved education activities and background information from a spectrum of NASA missions and programs. The Universe Discovery Guides are downloadable from the NASA Night Sky Network web site at nightsky.jpl.nasa.gov. We will share the Forum-led Collaborative's experience in developing the guides, how they place individual science discoveries and learning resources into context for audiences, and how the Guides can be readily used in scientist public outreach efforts, in college and university introductory astronomy classes, and in other engagements between scientists, students and the public.

    The participant countries in EPOS embody a wide range of world-class laboratory infrastructures ranging from high temperature and pressure experimental facilities, to electron microscopy, micro-beam analysis, analogue modeling and paleomagnetic laboratories. Most data produced by the various laboratory centres and networks are presently available only in limited "final form" in publications. As such many data remain inaccessible and/or poorly preserved. However, the data produced at the participating laboratories are crucial to serving society's need for geo-resources exploration and for protection against geo-hazards. Indeed, to model resource formation and system behaviour during exploitation, we need an understanding from the molecular to the continental scale, based on experimental data. This contribution will describe the work plans that the laboratories community in Europe is making, in the context of EPOS. The main objectives are: - To collect and harmonize available and emerging laboratory data on the properties and processes controlling rock system behaviour at multiple scales, in order to generate products accessible and interoperable through services for supporting research activities. - To co-ordinate the development, integration and trans-national usage of the major solid Earth Science laboratory centres and specialist networks. The length scales encompassed by the infrastructures included range from the nano- and micrometer levels (electron microscopy and micro-beam analysis) to the scale of experiments on centimetre sized samples, and to analogue model experiments simulating the reservoir scale, the basin scale and the plate scale. - To provide products and services supporting research into Geo-resources and Geo-storage, Geo-hazards and Earth System Evolution.

  7. Defining an EPOR- regulated transcriptome for primary progenitors, including Tnfr-sf13c as a novel mediator of EPO- dependent erythroblast formation.

    Directory of Open Access Journals (Sweden)

    Seema Singh

    Full Text Available Certain concepts concerning EPO/EPOR action modes have been challenged by in vivo studies: Bcl-x levels are elevated in maturing erythroblasts, but not in their progenitors; truncated EPOR alleles that lack a major p85/PI3K recruitment site nonetheless promote polycythemia; and Erk1 disruption unexpectedly bolsters erythropoiesis. To discover novel EPO/EPOR action routes, global transcriptome analyses presently are applied to interrogate EPO/EPOR effects on primary bone marrow-derived CFUe-like progenitors. Overall, 160 EPO/EPOR target transcripts were significantly modulated 2-to 21.8-fold. A unique set of EPO-regulated survival factors included Lyl1, Gas5, Pim3, Pim1, Bim, Trib3 and Serpina 3g. EPO/EPOR-modulated cell cycle mediators included Cdc25a, Btg3, Cyclin-d2, p27-kip1, Cyclin-g2 and CyclinB1-IP-1. EPO regulation of signal transduction factors was also interestingly complex. For example, not only Socs3 plus Socs2 but also Spred2, Spred1 and Eaf1 were EPO-induced as negative-feedback components. Socs2, plus five additional targets, further proved to comprise new EPOR/Jak2/Stat5 response genes (which are important for erythropoiesis during anemia. Among receptors, an atypical TNF-receptor Tnfr-sf13c was up-modulated >5-fold by EPO. Functionally, Tnfr-sf13c ligation proved to both promote proerythroblast survival, and substantially enhance erythroblast formation. The EPOR therefore engages a sophisticated set of transcriptome response circuits, with Tnfr-sf13c deployed as one novel positive regulator of proerythroblast formation.

    Laboratory facilities are an integral part of Earth Science research. The diversity of methods employed in such infrastructures reflects the multi-scale nature of the Earth system and is essential for the understanding of its evolution, for the assessment of geo-hazards and for the sustainable exploitation of geo-resources. In the frame of EPOS (European Plate Observing System), the Working Package 16 represents a developing community of European Geoscience Multi-scale laboratories. The participant and collaborating institutions (Utrecht University, GFZ, RomaTre University, INGV, NERC, CSIC-ICTJA, CNRS, LMU, C4G-UBI, ETH, CNR*) embody several types of laboratory infrastructures, engaged in different fields of interest of Earth Science: from high temperature and pressure experimental facilities, to electron microscopy, micro-beam analysis, analogue tectonic and geodynamic modelling and paleomagnetic laboratories. The length scales encompassed by these infrastructures range from the nano- and micrometre levels (electron microscopy and micro-beam analysis) to the scale of experiments on centimetres-sized samples, and to analogue model experiments simulating the reservoir scale, the basin scale and the plate scale. The aim of WP16 is to provide two services by the year 2019: first, providing virtual access to data from laboratories (data service) and, second, providing physical access to laboratories (transnational access, TNA). Regarding the development of a data service, the current status is such that most data produced by the various laboratory centres and networks are available only in limited "final form" in publications, many data remain inaccessible and/or poorly preserved. Within EPOS the TCS Multi-scale laboratories is collecting and harmonizing available and emerging laboratory data on the properties and process controlling rock system behaviour at all relevant scales, in order to generate products accessible and interoperable through services for supporting

In a special run with $\\beta^*=90$ m beam optics corresponding to an integrated luminosity of 80 $\\text{mb}^{-1}$ the differential elastic cross section is measured in the range from $-t=0.0025\\text{ GeV}^2$ to $-t=0.38\\text{ GeV}^2$. The total cross section $\\sigma(pp\\rightarrow X)$ is extracted using the Optical Theorem by extrapolation of the differential elastic cross section to $t=0\\text{ GeV}^2$. Prospects for diffractive measurements using ALFA to detect the intact proton(s) is also discussed.

    A middle-aged man was admitted to the ED because of nausea and vomiting, abdominal distention and fainting. A blood analysis revealed high levels of serum amylase and lipase, confirming a diagnosis of acute pancreatitis. The history showed that the patient had self-administered a single dose of pegylated interferon alfa-2b and ribavirin daily for 7 days for chronic hepatitis C. The medications were stopped and his condition gradually improved. In agreement with the literature and the Naranjo algorythm result, pegylated interferon alfa-2b is associated with acute pancreatitis. Identification of a few signs and symptoms is the first 'signal' in preventing a serious drug-induced adverse event.

    The Climate Discovery Exhibit at the National Center for Atmospheric Research (NCAR) Mesa Lab provides an exciting conceptual outline for the integration of several EPO activities with other well-established NCAR educational resources and programs. The exhibit is organized into four topic areas intended to build understanding among NCAR's 80,000 annual visitors, including 10,000 school children, about Earth system processes and scientific methods contributing to a growing body of knowledge about climate and global change. These topics include: 'Sun-Earth Connections,' 'Climate Now,' 'Climate Past,' and 'Climate Future.' Exhibit text, graphics, film and electronic media, and interactives are developed and updated through collaborations between NCAR's climate research scientists and staff in the Office of Education and Outreach (EO) at the University Corporation for Atmospheric Research (UCAR). With funding from NCAR, paleoclimatologists have contributed data and ideas for a new exhibit Teachers' Guide unit about 'Climate Past.' This collection of middle-school level, standards-aligned lessons are intended to help students gain understanding about how scientists use proxy data and direct observations to describe past climates. Two NASA EPO's have funded the development of 'Sun-Earth Connection' lessons, visual media, and tips for scientists and teachers. Integrated with related content and activities from the NASA-funded Windows to the Universe web site, these products have been adapted to form a second unit in the Climate Discovery Teachers' Guide about the Sun's influence on Earth's climate. Other lesson plans, previously developed by on-going efforts of EO staff and NSF's previously-funded Project Learn program are providing content for a third Teachers' Guide unit on 'Climate Now' - the dynamic atmospheric and geological processes that regulate Earth's climate. EO has plans to collaborate with NCAR climatologists and computer modelers in the next year to develop

    Full Text Available Nanocellulose (NC were extracted from the Moroccan Alfa plant (Stipa tenacissima L. and characterised. These Alfa cellulosic nanoparticles were used as reinforcing phase to prepare bionanocomposite films using carboxymethyl cellulose as matrix. These films were obtained by the casting/evaporation method. The crystallinity of NC was analysed by X-ray diffraction, the dimension of NC by atomic force microscopy, molecular interactions due to incorporation of NC in carboxymethyl cellulose (CMC matrix were supported by Fourier transforms infrared (FTIR spectroscopy. The properties of the ensuing bionanocomposite films were investigated using tensile tests, water vapour permeability (WVP study and thermogravimetric analysis. With the progress of purification treatment of cellulose, the crystallinity is improved compared to the untreated fibres; this can be explained by the disappearance of the amorphous areas in cellulose chain of the plant. Consequently, the tensile modulus and tensile strength of CMC film increased by 60 and 47%, respectively, in the bionanocomposite films with 10 wt% of NC, and decrease by 8.6% for WVP with the same content of NC. The NC obtained from the Moroccan Alfa fibres can be used as a reinforcing agent for the preparation of bionanocomposites, and they have a high potential for the development of completely biodegradable food packaging materials.

    To demonstrate, using human factors engineering (HFE), that a redesigned, pre-filled, ready-to-use, pre-asembled follitropin alfa pen can be used to administer prescribed follitropin alfa doses safely and accurately. A failure modes and effects analysis identified hazards and harms potentially caused by use errors; risk-control measures were implemented to ensure acceptable device use risk management. Participants were women with infertility, their significant others, and fertility nurse (FN) professionals. Preliminary testing included 'Instructions for Use' (IFU) and pre-validation studies. Validation studies used simulated injections in a representative use environment; participants received prior training on pen use. User performance in preliminary testing led to IFU revisions and a change to outer needle cap design to mitigate needle stick potential. In the first validation study (49 users, 343 simulated injections), in the FN group, one observed critical use error resulted in a device design modification and another in an IFU change. A second validation study tested the mitigation strategies; previously reported use errors were not repeated. Through an iterative process involving a series of studies, modifications were made to the pen design and IFU. Simulated-use testing demonstrated that the redesigned pen can be used to administer follitropin alfa effectively and safely.

    Full Text Available Background: Biofeedback is a technique in which people are trained to improve their health by learning to control certain internal bodily processes that normally occur involuntarily. Various studies in the past have shown usefulness of Alfa electroencephalographic (EEG biofeedback in the alleviation of anxiety symptoms. Though most of the psychiatric centers in the armed forces have this facility, not much work has been done in our setup to assess its efficacy in the management of anxiety. Hence this study was undertaken. Materials and Methods: This study was carried out in a multispecialty Command Hospital by enrolling 100 patients with psychiatric diagnosis from both inpatient and outpatient services. The anxiety level was assessed clinically and by using Hamilton Anxiety Scale and Taylor′s Manifest Anxiety Scale. One group of 50 patients was treated with Alfa EEG biofeedback sessions only, 5 times in a week for 8 weeks, along with specific pharmacotherapy. The other group was treated with appropriate dose of anxiolytics. The anxiety level was reassessed after 4 weeks and 8 weeks. Results: The response was better for mixed anxiety and depressive disorder with pharmacotherapy than with the biofeedback, but female patients showed better response with EEG biofeedback. Conclusion: In the short term, Alfa EEG biofeedback therapy is almost as efficacious as pharmacological intervention in the management of anxiety symptoms, and relatively more useful in females.

    Novel raft forming systems incorporating curcumin-Eudragit® EPO solid dispersions were developed to prolong the gastric residence time and provide for a controlled release therapy of curcumin to treat gastric ulcers. The solid dispersions of curcumin with Eudragit® EPO were prepared by the solvent evaporation method at various ratios to improve the solubility and the dissolution of curcumin. The optimum weight ratio of 1:5 for curcumin to Eudragit® EPO was used to incorporate into the raft forming systems. The raft forming formulations were composed of curcumin-Eudragit® EPO solid dispersions, sodium alginate as a gelling polymer and calcium carbonate for generating divalent Ca(2+) ions and carbon dioxide to form a floating raft. All formulations formed a gelled raft in 1min and sustained buoyancy on the 0.1N hydrochloric acid (pH 1.2) surface with a 60-85% release of curcumin within 8h. The curative effect on the acetic acid-induced chronic gastric ulcer in rats was determined. The curcumin raft forming formulations at 40mg/kg once daily showed a superior curative effect on the gastric ulcer in terms of the ulcer index and healing index than the standard antisecretory agent: lansoprazole (1mg/kg, twice daily) and a curcumin suspension (40mg/kg, twice daily). These studies demonstrated that the new raft forming systems containing curcumin solid dispersions are promising carriers for a stomach-specific delivery of poorly soluble lipophilic compounds.

    1997-01-01

    Hematologic effects of granulocyte colony-stimulating factor (G-CSF) and erythropoietic (EPO) combination after priming intensive chemotherapy in the treatment of female breast carcinoma are presented. In a previous group treated with G-CSF alone, 36% of patients became anemic and to be transfused for correction of their anemia. To the present study consecutive patients with different stages of breast carcinoma were admitted. All were given priming intensive chemotherapy (epirubicin 150 m/m 2 and cyclophosphamide 1300 mg/m 2 ) followed by subcutaneous application of G-CSF at a dose of 5 μg/kg/day and EPO 250 IU/kg/day. In cases where leucocyte counts dropped below 1 x 10 9 /dm 3 and hemoglobin level fell to 85 g/dm 3 administration of growth factors was started. The therapy was stopped when normal leukocyte count reached 4 x 10 9 /dm 3 for G-CSF and hemoglobin level rose to 115 g/dm 3 for EPO. Our results show significant difference between MNC/Tl (min.), CD34 + cells/μl (min.), CFU-GM/ml (min.), BFU-E/ml (min) and MNC/μl (max.), CD34 + cells/μl (max.), CFU-GM/ml (max.), BFU-E/ml (ml) p + cells/μl, 23.4-fold for CFU-GM/ml and 28.7-fold increase for BFU-E/ml. Side effects were minimal, no infectious complications occurred, body temperature did not rise over 3 grad C and no corrections of anemia were needed. It is concluded that the administration of G-CSF plus EPO combination following intensive chemotherapy reduces hematologic toxicity and induces large amount of hemopoietic progenitors suitable for autologous transplantation in women with breast carcinoma.

  2. Practicing IEF-PAGE of EPO: the impact of detergents and sample application methods on analytical performance in doping control.

    Reichel, Christian

    2010-01-01

    Electrophoretic techniques, namely isoelectric focusing polyacrylamide gel electrophoresis (IEF-PAGE) and sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) are key techniques used for confirming the doping-related abuse of recombinant erythropoietins and analogs. IEF-PAGE is performed on horizontal slab-gels with samples applied to the surface of the gel. Different sample application techniques can be employed, but application pieces and applicator strips are most frequently used. However, defective application pieces cause lane streaking during IEF of erythropoietin (EPO), which is especially pronounced in the acidic region of the gel. The effect is due to an incompatibility of the substance used for enhancing the wettability of the cellulose-based commercial product and is batch-dependent. A detailed mass spectrometric study was performed, which revealed that defective sample application pieces (bought between 2007 and 2010) contained a complex mixture of alcohol ethoxylates, alcohol ethoxysulfates, and alkyl sulfates (e.g. SDS). Anionic detergents, like the sulfates contained in these application pieces, are in general incompatible with IEF. Alternative application techniques proved partly useful. While homemade pieces made of blotting paper are a good alternative, the usage of applicator strips or shims is hampered by the risk of leaking wells, which lead to laterally diffused samples. Casting IEF-gels with wells appears to be the best solution, since sustained release of retained proteins from the application pieces can be avoided. Edge effects do not occur if wells are correctly filled with the samples. The evaluation of EPO-profiles with defects is prohibited by the technical document on EPO-analytics (TD2009EPO) of the World Anti-Doping Agency (WADA). Copyright © 2010 John Wiley & Sons, Ltd.

    Full Text Available We present here a novel conjugated aptamer-gold nanoparticle (Apt-AuNPs fluorescent probe and its application for specific detection of recombinant human erythropoietin-α (rHuEPO-α. In this nanobiosensor, 12 nm AuNPs function as both a nano-scaffold and a nano-quencher (fluorescent energy acceptor, on the surface of which the complementary sequences are linked (as cODN-AuNPs and pre-hybridized with carboxymethylfluorescein (FAM-labeled anti-rHuEPO-α aptamers. Upon target protein binding, the aptamers can be released from the AuNP surface and the fluorescence signal is restored. Key variables such as the length of linker, the hybridization site and length have been designed and optimized. Full performance evaluation including sensitivity, linear range and interference substances are also described. This nanobiosensor provides a promising approach for a simple and direct quantification of rHuEPO-α concentrations as low as 0.92 nM within a few hours.

    2010-01-01

    Background Gain-of-function of erythropoietin receptor (EPOR) mutations represent the major cause of primary hereditary polycythemia. EPOR is also found in non-erythroid tissues, although its physiological role is still undefined. Methodology/Principal Findings We describe a family with polycythemia due to a heterozygous mutation of the EPOR gene that causes a G→T change at nucleotide 1251 of exon 8. The novel EPOR G1251T mutation results in the replacement of a glutamate residue by a stop codon at amino acid 393. Differently from polycythemia vera, EPOR G1251T CD34+ cells proliferate and differentiate towards the erythroid phenotype in the presence of minimal amounts of EPO. Moreover, the affected individuals show a 20-fold increase of circulating endothelial precursors. The analysis of erythroid precursor membranes demonstrates a heretofore undescribed accumulation of the truncated EPOR, probably due to the absence of residues involved in the EPO-dependent receptor internalization and degradation. Mutated receptor expression in EPOR-negative cells results in EPOR and Stat5 phosphorylation. Moreover, patient erythroid precursors present an increased activation of EPOR and its effectors, including Stat5 and Erk1/2 pathway. Conclusions/Significance Our data provide an unanticipated mechanism for autosomal dominant inherited polycythemia due to a heterozygous EPOR mutation and suggest a regulatory role of EPO/EPOR pathway in human circulating endothelial precursors homeostasis.

    In the past two decades plants have emerged as a valuable alternative for the production of pharmaceutical proteins. Since N-glycosylation influences functionality and stability of therapeutic proteins, the plant N-glycosylation pathway should be humanized. Here, we report the transient magnICON(®) expression of the erythropoietin fusion protein (EPO-Fc) in Nicotiana benthamiana plants that produce multi-antennary N-glycans without the plant-specific β1,2-xylose and α1,3-fucose residues in a stable manner (Nagels et al., 2011). The EPO-Fc fusion protein consists of EPO with a C-terminal-linked IgG-Fc domain and is used for pulmonary delivery of recombinant EPO to patients (Bitonti et al., 2004). Plant expressed EPO-Fc was quantified using a paramagnetic-particle chemiluminescent immunoassay and shown to be active in vitro via receptor binding experiments in HEK293T cells. Mass spectrometry-based N-glycan analysis confirmed the presence of multi-antennary N-glycans on plant-expressed EPO-Fc. The described research is the next step towards the development of a production platform for pharmaceutical proteins in plants. Copyright © 2012 Elsevier B.V. All rights reserved.

  7. Federal STEM Policy and Politics and Their Impact on Astronomy EPO: Reflections and Provocations

    2015-11-01

    The federal government invests more than $3 billion each year across its various units in supporting STEM education and outreach. Efforts in recent years to understand and better coordinate these investments have resulted in considerable pushback, particularly those efforts that aimed at consolidation and elimination of programs deemed ineffective or duplicative. While initial plans to streamline federal STEM education were defeated, many agencies nonetheless saw cuts and elimination, and a high-level effort to coordinate STEM education at the cross-agency level is now gaining steam (CoSTEM: Committee on Science, Technology, Engineering, and Mathematics Education). What do all of these developments mean for education and public outreach in astronomy and related fields? How should this community operate within the opportunities and threats that CoSTEM might pose? Former director of the National Academy of Science's Board on Science Education, and now director of the Center for Research on Lifelong STEM Learning, Martin Storksdieck, reflected on past and recent developments from the perspective of a close observer, and from the perspective of someone who has been involved in astronomy education research and evaluation for nearly 20 years. Shelley Canright, Senior Advisor for Education Integration at the NASA Office of Education, shared her insights and perspectives with respect to CoSTEM and EPO, in particular from co-chairing the Federal Coordination in Science, Technology, Engineering, and Mathematics Education (FC-STEM) group.

    The Caltech Tectonics Observatory (TO) is an interdisciplinary center, focused on geological processes occurring at the boundaries of Earth's tectonic plates (http://www.tectonics.caltech.edu). Over the past year, the TO has made a major effort to develop an Education and Public Outreach (EPO) program. Our goals are to (1) stimulate the interest of students and the general public in Earth Sciences, particularly in the study of tectonic processes, (2) inform and educate the general public about science in the context of TO discoveries and advancements, and (3) provide opportunities for graduate students, postdocs, and faculty to do outreach in the local K-12 schools. We have hosted local high school students and teachers to provide them with research experience (as part of Caltech’s “Summer Research Connection”); participated in teacher training workshops (organized by the local school district); hosted tours for local elementary school students; and brought hands-on activities into local elementary and middle school classrooms, science clubs, and science nights. We have also led local school students and teachers on geology field trips through nearby parks. In addition, we have developed education modules for undergraduate classes (as part of MARGINS program), and have written educational web articles on TO research (http://www.tectonics.caltech.edu/outreach). The presentation will give an overview of these activities and their impact on our educational program.

    The Caltech Tectonics Observatory (TO) is an interdisciplinary center, focused on geological processes occurring at the boundaries of Earth's tectonic plates (http://www.tectonics.caltech.edu). Over the past four years, the TO has made a major effort to develop an Education and Public Outreach (EPO) program. Our goals are to (1) inspire students to learn Earth Sciences, particularly tectonic processes, (2) inform and educate the general public about science in the context of TO discoveries, and (3) provide opportunities for graduate students, postdocs, and faculty to do outreach in the local K-12 schools and community colleges. Our work toward these goals includes hosting local high school teachers and students each summer for six weeks of research experience (as part of Caltech's "Summer Research Connection"); organizing and hosting an NAGT conference aimed at Geoscience teachers at community colleges; participating in teacher training workshops (organized by the local school district); hosting tours for K-12 students from local schools as well as from China; and bringing hands-on activities into local elementary, middle, and high school classrooms. We also lead local school students and teachers on geology field trips through nearby canyons; develop education modules for undergraduate classes (as part of MARGINS program); write educational web articles on TO research (http://www.tectonics.caltech.edu/outreach/highlights/), and regularly give presentations to the general public. This year, we started providing content expertise for the development of video games to teach Earth Science, being created by GameDesk Institute. And we have just formed a scientist/educator partnership with a 6th grade teacher, to help in the school district's pilot program to incorporate new national science standards (NSTA's Next Generation Science Standards, current draft), as well as use Project-Based Learning. This presentation gives an overview of these activities.

    The observations of the Atmospheric Imaging Assembly aboard the Solar Dynamics Observatory (SDO-AIA) are expected to be groundbreaking within the field of heliophysics. To properly promote and explain the data produced by AIA, it is important that an innovative EPO effort be put forth. This has led to the development of "The AIA Solar Learning Center” (SLC), an inquiry-based educational website geared towards teaching about AIA and the Sun in general. The goal of the SLC is to provide K-12 students, teachers, parents, and homeschoolers with information and education about the Sun, primarily through hands-on activity modules that explain different aspects of our nearest star and the methods of observing it. While each module ultimately aims to impart information about the Sun or some related physical process, the activities also range across a host of different disciplines, including geology, chemistry, history, music, and art. In order to make the content applicable and accessible, activities are tailored to multiple difficulty levels, catering to different age groups. There is also a strong push towards facilitating teachers; activities are designed to fulfill specific teaching standards, and a host of additional teaching material is provided, including lesson plans and powerpoint presentations. Ultimately, the SLC aims to make science and the Sun inviting and accessible. The "Meet the Scientists” page will provide pictures and personal bios of participating scientists. Students will have the opportunity to interactively ask solar-related questions. There is even a host of lighter fare, such as a solar music playlist and links to relevant Facebook pages.

    2015-01-01

    FAIR is a new, unique international accelerator facility for the research with antiprotons and ions. It is being built at the GSI Darmstadt in Hesse, Germany. The commonalities between the ALICE and FAIR experiments and their computing requirements led to the development of a common software framework in an experiment independent way; ALFA (ALICE-FAIR framework). ALFA is designed for high quality parallel data processing and reconstruction on heterogeneous computing systems. It provides a data transport layer and the capability to coordinate multiple data processing components. ALFA is a flexible, elastic system which balances reliability and ease of development with performance by using a message based multi-processing in addition to multi-threading. The framework allows for usage of heterogeneous computing architectures by offloading (portions of code are accelerated on the device) or natively (where the full program is executed on the device ).

    The release of corifollitropin alfa simplifies daily injections of short-acting recombinant follicular stimulating hormone (rFSH), and its widely-used protocol involves short-acting gonadotropins supplements and a fixed GnRH antagonist regimen, largely based on follicle size. In this study, the feasibility of corifollitropin alfa without routine pituitary suppression was evaluated. A total of 288 patients were stimulated by corifollitropin alfa on cycle day 3 following with routine serum hormone monitoring and follicle scanning every other day after 5 days of initial stimulation, and a GnRH antagonist (0.25 mg) was only used prophylactically when the luteinizing hormone (LH) was ≧ 6 IU/L (over half of the definitive LH surge). The incidence of premature LH surge (≧ 10 IU/L) was 2.4% (7/288) before the timely injection of a single GnRH antagonist, and the elevated LH level was dropped down from 11.9 IU/L to 2.2 IU/L after the suppression. Two hundred fifty-one patients did not need any antagonist (87.2% [251/288]) throughout the whole stimulation. No adverse effects were observed regarding oocyte competency (fertilization rate: 78%; blastocyst formation rate: 64%). The live birth rate per OPU cycle after the first cryotransfer was 56.3% (161/286), and the cumulative live birth rate per OPU cycle after cyrotransfers was 69.6% (199/286). Of patients who did and did not receive GnRH antagonist during stimulation, no significant difference existed in the cumulative live birth rates (78.4% vs. 68.3%, p = 0.25). The results demonstrated that the routine GnRH antagonist administration is not required in the corifollitropin-alfa cycles using a flexible and hormone-depended antagonist regimen, while the clinical outcome is not compromised. This finding reveals that the use of a GnRH antagonist only occasionally may be needed.

    Full Text Available The release of corifollitropin alfa simplifies daily injections of short-acting recombinant follicular stimulating hormone (rFSH, and its widely-used protocol involves short-acting gonadotropins supplements and a fixed GnRH antagonist regimen, largely based on follicle size.

    Several studies have reported that low doses of interferon can delay the development of hepatocellular carcinoma (HCC) and progression of chronic hepatitis C. We investigated the incidence of clinical events among participants of the Evaluation of PegIntron in Control of Hepatitis C Cirrhosis (EPIC)3 program. Data were analyzed from an open-label randomized study of patients with chronic hepatitis C who had failed to respond to interferon alfa plus ribavirin. All patients had compensated cirrhosis with no evidence of HCC. Patients received peginterferon alfa-2b (0.5 μg/kg/week; n=311) or no treatment (controls, n=315) for a maximum period of 5 years or until 98 patients had a clinical event (hepatic decompensation, HCC, death, or liver transplantation). The primary measure of efficacy was time until the first clinical event. There was no significant difference in time to first clinical event among patients who received peginterferon alfa-2b compared with controls (hazard ratio [HR], 1.452; 95% confidence interval [CI]: 0.880-2.396). There was no decrease in the development of HCC with therapy. The time to disease progression (clinical events or new or enlarged varices) was significantly longer for patients who received peginterferon alfa-2b compared with controls (HR, 1.564; 95% CI: 1.130-2.166). In a prospectively defined subanalysis of patients with baseline portal hypertension, peginterferon alfa-2b significantly increased the time to first clinical event compared with controls (P=.016). There were no new safety observations. Maintenance therapy with peginterferon alfa-2b is not warranted in all patients and does not prevent HCC. However, there is a potential clinical benefit of long-term suppressive therapy in patients with preexisting portal hypertension. Copyright © 2011 AGA Institute. Published by Elsevier Inc.

    Full Text Available Objectve. The Rh-hemolytic disease can lead to a late anemia by hemolytic and hyporigenerative mechanism. We compared the effectiveness of rHuEPO in two care protocols that differ for doses of rHuEPO administrated and for timing of administration. Methods. A cohort of 14 neonates was investigated. The neonates were treated with two different protocols. Protocol A: a dose of 200 U/kg/day of rHuEpo administered subcutaneously starting from the end of the second week of life; Protocol B: a dose of 400 U/kg/day of rHuEpo administered subcutaneously starting from the end of the first week of life. Results. The hematocrit values in the protocol A group decreased during treatment (32,5% vs 25,2%, whereas the hematocrit value in protocol B group remained almost stable (38,7% vs 42,8%. The mean numbers of platelets remained stable in both groups while neutrophils increased in protocol A group and decreased in protocol B (p<0,05. Reticulocyte count increased during treatment in both groups, although only in protocol B group it was statistically significative (p<0,05. Conclusions. Our results suggest a similar efficacy between the two treatment protocols. Increasing doses of rHuEPO do not seem enhancing their effectiveness and the incidence of side effects.

    B2SAFE is the EUDAT service for moving and replicating data between sites and storage systems for different purposes. The goal of B2SAFE is to keep the data from a repository safe by replicating it across different geographical and administrative zones according to a set of well-defined policies. It is also a way to store large volumes of data permanently at those sites which are providing powerful on-demand data analysis facilities. In particular, B2SAFE operates on the domain of registered data where data objects are referable via persistent identifiers (PIDs). B2SAFE is more than just copying data because the PIDs must be carefully managed when data objects are moved or replicated. The EUDAT B2SAFE Service offers functionality to replicate datasets across different data centres in a safe and efficient way while maintaining all information required to easily find and query information about the replica locations. The information about the replica locations and other important information is stored in PID records, each managed in separate administrative domains. The B2SAFE Service is implemented as an iRODS module providing a set of iRODS rules or policies to interface with the EPIC handle API and uses the iRODS middleware to replicate datasets from a source data (or community) centre to a destination data centre. The definition of the dataset(s) to replicate is flexible and up to the communities using the B2SAFE service. While the B2SAFE is internally using the EPIC handle API, communities have the choice to use any PID system they prefer to assign PIDs to their digital objects. A reference to one or more EUDAT B2SAFE PIDs is returned by the B2SAFE service when a dataset is replicated. The presentation will introduce the problem space of B2SAFE, presents the achievements that have been made during the last year for enabling communities to make use of the B2SAFE service, demonstrates a EPOS use cases, outlines the commonalities and differences between the policies

    The Earth Forum Education and Public Outreach (EP/O) community has long interacted to better their practice as a community as well as individually. Working together to share knowledge and grow, they function as a community of practice. In 2009, NASA designed and implemented an online workspace in hopes of promoting the communities continued interactions. This study examines the role of an online workspace component of a community in the work of a community of practice. Much has been studied revealing the importance of communities of practice to organizations, project success, and knowledge management and some of these same successes hold true for virtual communities of practice. Study participants were 75 Education and Public Outreach community members of NASA's Science Mission Directorate Earth Forum. In this mixed methods study, online workspace metrics were used to track participation and a survey completed by 21 members was used to quantify participation. For a more detailed analysis, 15 community members (five highly active users, five average users, and five infrequent users) selected based on survey responses, were interviewed. Finally, survey data was gathered from seven online facilitators to understand their role in the community. Data collected from these 21 community members and five facilitating members suggest that highly active users (logging into the workspace daily), were more likely to have transformative experiences, co-create knowledge, feel ownership of community knowledge, have extended opportunities for community exchange, and find new forms of evaluation. Average users shared some similar characteristics with both the highly active members and infrequent users, representing a group in transition as they become more engaged and active in the online workspace. Inactive users viewed the workspace as having little value, being difficult to navigate, being mainly for gaining basic information about events and community news, and as another demand

    Full Text Available Many cereal straws have been used as raw materials for the preparation of microcrystalline cellulose (MCC. These raw materials were gradually replaced with wood products; nevertheless about 10% of the world overall pulp production is obtained from non-wood raw material. The main interest in pulp made from straw is that it provides excellent fibres for different industries with special properties, and that it is the major available source of fibrous raw material in some geographical areas. The aim of the present work was to characterize microcrystalline cellulose prepared from alfa fibers using the hydrolysis process. The products obtained are characterized with FTIR spectroscopy and X-ray powder diffraction. As a result, FTIR spectroscopy is an appropriate technique for studying changes occurred by any chemical treatment. The spectrum of alfa grass stems shows the presence of lignin and hemicelluloses. However, the cellulose spectrum indicates that the extraction of lignin and hemicellulose was effective. The X-ray analysis indicates that the microcrystalline cellulose is more crystalline than the source material.

    Plants are a promising alternative for the production of biotherapeutics. Manufacturing in-planta adds plant specific glycans. To understand immunogenic potential of these glycans, we developed a validated method to detect plant specific glycan antibodies in human serum. Using this assay, low prevalence of pre-existing anti-plant glycan antibodies was found in healthy humans (13.5%) and in glucocerebrosidase-deficient Gaucher disease (GD) patients (5%). A low incidence (9% in naïve patient and none in treatment experienced patients) of induced anti-plant glycan antibodies was observed in GD patients after up to 30 months replacement therapy treatment with taliglucerase alfa, a version of human glucocerebrosidase produced in plant cells. Detailed evaluation of clinical safety and efficacy endpoints indicated that anti-plant glycan antibodies did not affect the safety or efficacy of taliglucerase alfa in patients. This study shows the benefit of using large scale human trials to evaluate the immunogenicity risk of plant derived glycans, and indicates no apparent risk related to anti-plant glycan antibodies.

    To observe change of binding activity of HIF-1 with erythropoietin (EPO) hypoxia response element (HRE) in the hippocampus of mice preconditioned to hypoxia and explore relationship between the changes and the preconditioning. The hippocampus was removed from mice exposed to hypoxia for 0 run (control group), 1 run (H1 group) and 4 runs(H4 group). Electrophoretic mobility shift assays (EMSA), chromatin immunoprecipitation (ChIP)and real time PCR were used to detect the change of activity of HIF-1 on HRE of EPO. Both in vitro and in vivo binding tests showed that the HIF-1 DNA-binding activities were increased in group H1 and markedly increased in group H4. The increase of HIF-1 and HRE of EPO binding activities is thought be involved in hypoxic preconditioning.

    Full Text Available Patients treated with recombinant human Epo demonstrate an improvement in insulin sensitivity. We aimed to investigate whether CNTO 530, a novel Epo receptor agonist, could affect glucose tolerance and insulin sensitivity. A single administration of CNTO 530 significantly and dose-dependently reduced the area under the curve in a glucose tolerance test in diet-induced obese and diabetic mice after 14, 21, and 28 days. HOMA analysis suggested an improvement in insulin sensitivity, and this effect was confirmed by a hyperinsulinemic-euglycemic clamp. Uptake of 14C-2-deoxy-D-glucose indicated that animals dosed with CNTO 530 transported more glucose into skeletal muscle and heart relative to control animals. In conclusion, CNTO530 has a profound effect on glucose tolerance in insulin-resistant rodents likely because of improving peripheral insulin sensitivity. This effect was observed with epoetin-α and darbepoetin-α, suggesting this is a class effect, but the effect with these compounds relative to CNTO530 was decreased in duration and magnitude.

    A poor response to erythropoiesis-stimulating agents such as darbepoetin alfa has been associated with adverse outcomes in patients with diabetes mellitus, chronic kidney disease, and anemia; whether this is also true in heart failure is unclear. We performed a post hoc analysis of the RED-HF trial (Reduction of Events by Darbepoetin Alfa in Heart Failure), in which 1008 patients with systolic heart failure and anemia (hemoglobin level, 9.0-12.0 g/dL) were randomized to darbepoetin alfa. We examined the relationship between the hematopoietic response to darbepoetin alfa and the incidence of all-cause death or first heart failure hospitalization during a follow-up of 28 months. For the purposes of the present study, patients in the lowest quartile of hemoglobin change after 4 weeks were considered nonresponders. The median initial hemoglobin change in nonresponders (n=252) was -0.25 g/dL and +1.00 g/dL in the remainder of patients (n=756). Worse renal function, lower sodium levels, and less use of angiotensin-converting enzyme inhibitors or angiotensin receptor blockers were independently associated with nonresponse. Although a low endogenous erythropoietin level helped to differentiate responders from nonresponders, its predictive value in a multivariable model was poor (C statistic=0.69). Nonresponders had a higher rate of all-cause death or first heart failure hospitalization (hazard ratio, 1.25; 95% confidence interval, 1.02-1.54) and a higher risk of all-cause mortality (hazard ratio, 1.30; 95% confidence interval, 1.04-1.63) than responders. A poor response to darbepoetin alfa was associated with worse outcomes in heart failure patients with anemia. Patients with a poor response were difficult to identify using clinical and biochemical biomarkers. URL: https://www.clinicaltrials.gov.

    Primary erythroid progenitors can be expanded by the synergistic action of erythropoietin (Epo), stem cell factor (SCF) and glucocorticoids. While Epo is required for erythropoiesis in general, glucocorticoids and SCF mainly contribute to stress erythropoiesis in hypoxic mice. This ability of normal

    Accurate whole-brain segmentation, or brain extraction, of magnetic resonance imaging (MRI) is a critical first step in most neuroimage analysis pipelines. The majority of brain extraction algorithms have been developed and evaluated for adult data and their validity for neonatal brain extraction, which presents age-specific challenges for this task, has not been established. We developed a novel method for brain extraction of multi-modal neonatal brain MR images, named ALFA (Accurate Learning with Few Atlases). The method uses a new sparsity-based atlas selection strategy that requires a very limited number of atlases 'uniformly' distributed in the low-dimensional data space, combined with a machine learning based label fusion technique. The performance of the method for brain extraction from multi-modal data of 50 newborns is evaluated and compared with results obtained using eleven publicly available brain extraction methods. ALFA outperformed the eleven compared methods providing robust and accurate brain extraction results across different modalities. As ALFA can learn from partially labelled datasets, it can be used to segment large-scale datasets efficiently. ALFA could also be applied to other imaging modalities and other stages across the life course.

    Full Text Available Introdução: Talassemia alfa é uma síndrome associada à redução da síntese de cadeias de globina do tipo alfa. A gravidade das manifestações clínicas está relacionada com a quantidade de globinas produzida e a estabilidade das cadeias beta presentes em excesso. A talassemia alfa mínima resulta da deleção de apenas um dos quatro genes a (-α/αα. Clinicamente apresenta anemia leve com microcitose ou ausência de anemia, sendo o diagnóstico realizado por meio de visualização da hemoglobina (Hb H por eletroforese alcalina em acetato de celulose ou por identificação de inclusões celulares de Hb H coradas pelo azul de crezil brilhante. Objetivo: Avaliar portadores de talassemia alfa e seus respectivos progenitores, correlacionando perfil hematológico e presença de Hb H, utilizando procedimentos laboratoriais clássicos em três diferentes amostragens. Discussão e conclusão: Os dados obtidos mostram que a presença de Hb H, indicativo de talassemia alfa, pode não ser confirmada em uma análise posterior. Entre os fatores que podem influenciar no não aparecimento de Hb H em pessoa comprovadamente com talassemia alfa está a deficiência de ferro. A talassemia alfa está associada a defeitos envolvendo os genes codificadores da cadeia alfa, mas também pode estar relacionada com desbalanciamento temporário na expressão dos genes globina, diminuição de alfa ou aumento de beta, o que poderia explicar o aparecimento de tetrâmeros de cadeia beta (Hb H, sugerindo diagnóstico de talassemia alfa mínima.Introduction: Alpha thalassemia is a syndrome with associated with the reduction of alpha globin chain synthesis.

    The High-Resolution Imaging Science Experiment’s E/PO has fielded several online citizen science projects. Our efforts are guided by HiRISE E/PO’s philosophy of providing innovative opportunities for students and the public to participate in the scientific discovery process. HiRISE Clickworkers, a follow-on to the original Clickworkers crater identification and size diameter marking website, provides an opportunity for the public to identify & mark over a dozen landform feature types in HiRISE images, including dunes, gullies, patterned ground, wind streaks, boulders, craters, layering, volcanoes, etc. In HiRISE Clickworkers, the contributor views several sample images showing variations of different landforms, and simply marks all the landform types they could spot while looking at a small portion of a HiRISE image. Contributors then submit their work & once validated by comparison to the output of other participants, results are then added to geologic feature databases. Scientists & others will eventually be able to query these databases for locations of particular geologic features in the HiRISE images. Participants can also mark other features that they find intriguing for the HiRISE camera to target. The original Clickworkers website pilot study ran from November 2000 until September 2001 (Kanefsky et al., 2001, LPSC XXXII). It was among the first online Citizen Science efforts for planetary science. In its pilot study, we endeavored to answer two questions: 1) Was the public willing & able to help science, & 2) Can the public produce scientifically useful results? Since its inception over 3,500,000 craters have been identified, & over 350,000 of these craters have been classified. Over 2 million of these craters were marked on Viking Orbiter image mosaics, nearly 800,000 craters were marked on Mars Orbiter Camera (MOC) images. Note that these are not counts of distinct craters. For example, each crater in the Viking orbiter images was counted by about 50

    The Johns Hopkins University Applied Physics Laboratory (JHU/APL) is the home to hundreds of scientists and engineers, all involved in research, design and implementation of space missions. Many of these people actively seek out ways to raise awareness and interest in the local community by visiting schools, giving public lectures and supporting events held at the laboratory. During the past few years, APL has begun to foster a number of firm partnerships with organizations to further these community opportunities and provide a test bed for both formal and informal education activities through the Space Department E/PO office One of our ongoing partnerships is with the Maryland Science Center in Baltimore. A continual challenge faced by museums is how to stay current and allow visitors to experience the immediacy and excitement of scientific discovery. To help meet these challenges, the Maryland Science Center houses "SpaceLink", the Nation's first space, science and astronomy update center. Part media center, part discovery room, and part newsroom, the exhibit is a multi-purpose Professional Development Site for educators and a "classroom of the future" for K 12 students. APL scientists and- engineers regularly support SpaceLink's flexible programming, including scientist in residence, monthly credited seminars for educators (Teachers' Thursdays), a menu of Classroom Programs on request, Distance Learning Teacher Presentations, and special Live Events to highlight mission milestones and space-related anniversaries. This allows the guest scientists and engineers to interact directly with the public. These events also compliment the APL exhibits housed at the Science Center. JHU/APL offers an exciting environment for the study of applications in space by hosting the annual Maryland Summer Center for Space Science sponsored by the Maryland State Department of Education. Rising 6t h and 7t h grade students learn to harness the power of technology and keep pace with

    Although an erythropoiesis-stimulating agent (ESA) is most frequently administered intravenously for treatment of anemia in patients with chronic kidney disease who are on dialysis, few studies have compared the efficacy of different intravenous (i.v.) dosing schedules. This multicenter, phase IIIb, open-label, controlled study randomized 289 stable hemodialysis patients to continue with conventional dosing of i.v. epoetin alfa or darbepoetin, or to switch to once-weekly i.v. epoetin alfa at the same cumulative weekly starting dose, to maintain hemoglobin levels at 11.0-13.0 g/dL, and within 1.0 g/dL of the baseline value. Hemoglobin levels and ESA doses were recorded every 4 weeks for 28 weeks. Hemoglobin levels fell significantly and ESA doses increased significantly between baseline and week 28 (mean of week 16-28 values) in the once-weekly epoetin alfa group, compared with the conventional treatment group (phemoglobin levels between the groups was 0.73 g/dL (greater than the threshold for therapeutic equivalence of 0.5 g/dL). The changes between groups from baseline was significant at all time points for hemoglobin levels (0.36, 0.46, 0.81, 0.87, 0.78, 0.62 and 0.49 g/dL) and from week 12 for ESA dose (718.5, 1,326.5, 1,732.0, 1,839.7 and 1,959.1 IU/week; p=0.005). Hemoglobin was maintained at the target level in 78% and 84% of patients on conventional dosing, and 67% and 64% of those on once-weekly epoetin alfa in the intention-to-treat (p=0.1) and per protocol (p=0.016) populations, respectively. This study did not show therapeutic equivalence of once-weekly i.v. epoetin alfa with conventional dosing regimens.

    Race has been shown to be a factor in the response to therapy for hepatitis C virus (HCV) infection, and limited data suggest that ethnic group may be as well; however, Latinos and other ethnic subpopulations have been underrepresented in clinical trials. We evaluated the effect of Latino ethnic background on the response to treatment with peginterferon alfa-2a and ribavirin in patients infected with HCV genotype 1 who had not been treated previously. In a multicenter, open-label, nonrandomized, prospective study, 269 Latino and 300 non-Latino whites with HCV infection received peginterferon alfa-2a, at a dose of 180 microg per week, and ribavirin, at a dose of 1000 or 1200 mg per day, for 48 weeks, and were followed through 72 weeks. The primary end point was a sustained virologic response. We enrolled Latinos whose parents and grandparents spoke Spanish as their primary language; nonwhite Latinos were excluded. Baseline characteristics were similar in the Latino and non-Latino groups, although higher proportions of Latino patients were 40 years of age or younger, had a body-mass index (BMI, the weight in kilograms divided by the square of the height in meters) of more than 27 or more than 30, and had cirrhosis. The rate of sustained virologic response was higher among non-Latino whites than among Latinos (49% vs. 34%, PLatino whites at week 4 (P=0.045) and throughout the treatment period (PLatino or non-Latino background was an independent predictor of the rate of sustained virologic response in an analysis adjusted for baseline differences in BMI, cirrhosis, and other characteristics. Adherence to treatment did not differ significantly between the two groups. The numbers of patients with adverse events and dose modifications were similar in the two groups, but fewer Latino patients discontinued therapy because of adverse events. Treatment with peginterferon alfa-2a and ribavirin for 48 weeks resulted in rates of sustained virologic response among patients

    2017-10-01

    ALICE (A Large Ion Collider Experiment) is a heavy-ion detector designed to study the physics of strongly interacting matter (the Quark-Gluon Plasma at the CERN LHC (Large Hadron Collider). ALICE has been successfully collecting physics data in Run 2 since spring 2015. In parallel, preparations for a major upgrade of the computing system, called O2 (Online-Offline), scheduled for the Long Shutdown 2 in 2019-2020, are being made. One of the major requirements of the system is the capacity to transport data between so-called FLPs (First Level Processors), equipped with readout cards, and the EPNs (Event Processing Node), performing data aggregation, frame building and partial reconstruction. It is foreseen to have 268 FLPs dispatching data to 1500 EPNs with an average output of 20 Gb/s each. In overall, the O2 processing system will operate at terabits per second of throughput while handling millions of concurrent connections. The ALFA framework will standardize and handle software related tasks such as readout, data transport, frame building, calibration, online reconstruction and more in the upgraded computing system. ALFA supports two data transport libraries: ZeroMQ and nanomsg. This paper discusses the efficiency of ALFA in terms of high throughput data transport. The tests were performed with multiple FLPs pushing data to multiple EPNs. The transfer was done using push-pull communication patterns and two socket configurations: bind, connect. The set of benchmarks was prepared to get the most performant results on each hardware setup. The paper presents the measurement process and final results - data throughput combined with computing resources usage as a function of block size. The high number of nodes and connections in the final set up may cause race conditions that can lead to uneven load balancing and poor scalability. The performed tests allow us to validate whether the traffic is distributed evenly over all receivers. It also measures the behaviour of

    The main objective of the "Shale gas exploration and exploitation induced risks - SHEER" project (Horizon 2020, call LCE 16-2014) is to develop a probabilistic methodology to assess and mitigate the short- and the long-term environmental risks associated with the exploration and exploitation of shale gas. To this end, the SHEER project makes use of a large amount of heterogeneous data of various types. This data, from different disciplines of science e.g. geophysical, geochemical, geological, technological, etc., must be homogenized, harmonized and made accessible exclusively for all project participants. This requires to develop an over-arching structure for high-level multidisciplinary data integration. The bespoke solution is provided by Thematic Core Service Anthropogenic Hazards (TCS AH) developed in the framework of European Plate Observing System Program (https://tcs.ah-epos.eu/, infrastructural projects IS-EPOS, POIG.02.03.00-14-090/13-00 and EPOS IP, H2020-INFRADEV-1-2015-1). TCS AH provides virtual access to a comprehensive, wide-scale and high quality research infrastructure in the field of induced seismicity and other anthropogenic hazards evoked by exploration and exploitation of geo-resources. TCS AH is designed as a functional e-research environment to ensure a researcher the maximum possible freedom for experimentation by providing a virtual laboratory flexible to create own workspace for processing streams. A data-management process promotes the use of research infrastructure in novel ways providing an access to (i) data gathered in the so-called "episodes", comprehensively describing a geophysical process, induced or triggered by human technological activity, which under certain circumstances can become hazardous for people, infrastructure and the environment, (ii) problem-oriented, specific services, with the particular attention devoted to methods analyzing correlations between technology, geophysical response and resulting hazards, (iii) the

    Full Text Available Pompe disease is a rare severe hereditary disease caused by excessive glycogen storage in organs and target tissues due to the acid α-glucosidase gene mutation. Infantile and adult Pompe disease is characterized by involvement of cardiovascular, respiratory and muscular systems in the pathological process. The only specific method of treating Pompe disease is enzyme replacement therapy (intravenous administration of recombinant human acid glucosidase, the effectiveness whereof depends on the time the therapy started. Since such a therapy was introduced into practice, Pompe disease mortality decreased by 79%. 6 children with infantile Pompe disease were observed and treated at the cardiovascular care unit of the Scientific Center of Children’s Health in 2011‑2014. The article presents a clinical case demonstrating capabilities of diagnosing infantile Pompe disease in Russia and effective application of alglucosidase alfa in 4-month-old child.

    Objective: To investigate the role of relevant cytokines in the development and pathogenesis of aplastic anemia. Methods: Plasma GM-CSF, IL-2, TPO (with RIA) and EPO (with CLIA) contents were measured in 100 patients (acute 43, chronic 57) with aplastic anemia and 50 controls. Complete blood count was also performed in all these subjects. Results: The peripheral RBC, WBC, platelet counts and GM-CSF contents were significantly lower in the patients with aplastic anemia than those in the controls (P<0.05), while the IL-2, EPO and TPO contents were significantly higher in the patients (P<0.05). GM-CSF contents were positively correlated with the WBC numbers. EPO contents were negatively correlated with the RBC counts and TPO contents were correlated (negatively) with the platelet counts. Conclusion: There was correlationship between each blood elements (WBC, RBC, platelet) and its corresponding cytokine (GS-CSF, EPO, TPO respectively). IL-2 contents were not correlated with WBC counts. (authors)

    Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) both have a role to play in follicular development during the natural menstrual cycle. LH supplementation during controlled ovarian stimulation (COS) for assisted reproductive technology (ART) is used for patients with hypogonadotropic hypogonadism. However, the use of exogenous LH in COS in normogonadotropic women undergoing ART is the subject of debate. The aim of this study was to investigate characteristics of infertile women who received the 2:1 formulation of follitropin alfa and lutropin alfa (indicated for stimulation of follicular development in women with severe LH and FSH deficiency) in German clinical practice. A 3-year, multicentre, open-label, observational/non-interventional, post-marketing surveillance study of women (21-45 years) undergoing ART. Primary endpoint: reason for prescribing the 2:1 formulation of follitropin alfa and lutropin alfa. Secondary variables included: COS duration/dose; oocytes retrieved; fertilization; clinical pregnancy; ovarian hyperstimulation syndrome (OHSS). In total, 2220 cycles were assessed; at least one reason for prescribing the 2:1 formulation was given in 1834/2220 (82.6%) cycles. Most common reasons were: poor ovarian response (POR) (39.4%), low baseline LH (17.8%), and age (13.8%). COS: mean dose of the 2:1 formulation on first day, 183.1/91.5 IU; mean duration, 10.8 days.

    Surgical audit is an essential task for the estimation of postoperative outcome and comparison of quality of care. Previous studies on surgical audits focused on short-term outcomes, such as postoperative mortality. We propose a surgical audit evaluating long-term outcome following colorectal cancer surgery. The predictive model for this audit is designated as 'Estimation of Postoperative Overall Survival for Colorectal Cancer (EPOS-CC)'. Thirty-one tumor-related and physiological variables were prospectively collected in 889 patients undergoing elective resection for colorectal cancer between April 2005 and April 2007 in 16 Japanese hospitals. Postoperative overall survival was assessed over a 5-years period. The EPOS-CC score was established by selecting significant variables in a uni- and multivariate analysis and allocating a risk-adjusted multiplication factor to each variable using Cox regression analysis. For validation, the EPOS-CC score was compared to the predictive power of UICC stage. Inter-hospital variability of the observed-to-estimated 5-years survival was assessed to estimate quality of care. Among the 889 patients, 804 (90%) completed the 5-years follow-up. Univariate analysis displayed a significant correlation with 5-years survival for 14 physiological and nine tumor-related variables (p model for the prediction of survival. Risk-adjusted multiplication factors between 1.5 (distant metastasis) and 0.16 (serum sodium level) were accorded to the different variables. The predictive power of EPOS-CC was superior to the one of UICC stage; area under the curve 0.87, 95% CI 0.85-0.90 for EPOS-CC, and 0.80, 0.76-0.83 for UICC stage, p < 0.001. Quality of care did not differ between hospitals. The EPOS-CC score including the independent variables age, performance status, serum sodium level, TNM stage, and lymphatic invasion is superior to the UICC stage in the prediction of 5-years overall survival. This higher accuracy might be explained by the

    Easy, efficient and comprehensive access to data, data products, scientific services and scientific software is a key ingredient in enabling research at the frontiers of science. Organizing this access across the European Research Infrastructures in the field of seismology, so that it best serves user needs, takes advantage of state-of-the-art ICT solutions, provides cross-domain interoperability, and is organizationally and financially sustainable in the long term, is the core challenge of the implementation phase of the Thematic Core Service (TCS) Seismology within the EPOS-IP project. Building upon the existing European-level infrastructures ORFEUS for seismological waveforms, EMSC for seismological products, and EFEHR for seismological hazard and risk information, and implementing a pilot Computational Earth Science service starting from the results of the VERCE project, the work within the EPOS-IP project focuses on improving and extending the existing services, aligning them with global developments, to at the end produce a well coordinated framework that is technically, organizationally, and financially integrated with the EPOS architecture. This framework needs to respect the roles and responsibilities of the underlying national research infrastructures that are the data owners and main providers of data and products, and allow for active input and feedback from the (scientific) user community. At the same time, it needs to remain flexible enough to cope with unavoidable challenges in the availability of resources and dynamics of contributors. The technical work during the next years is organized in four areas: - constructing the next generation software architecture for the European Integrated (waveform) Data Archive EIDA, developing advanced metadata and station information services, fully integrate strong motion waveforms and derived parametric engineering-domain data, and advancing the integration of mobile (temporary) networks and OBS deployments in

    Congenital nephrotic syndrome of the Finnish type (CNF) is due to NPHS1 mutation and is responsible for a variety of urinary protein losses. We report the case of a 4-month-old girl with a particularly severe form (proteinuria approximately 150 g/l) of CNF. She developed severe non-regenerative anaemia requiring bi-monthly blood transfusions despite daily EPO (600 UI/kg) and iron supplementation. Epoetin pharmacokinetics revealed a urinary loss of 27% of the given dose within the first 24 h after IV injection. However, plasma levels remained increased after 24 h (228 UI/l). Plasma transferrin and transcobalamin levels were undetectable. Atransferrinaemia and atranscobalaminaemia seem to be responsible for disturbed erythropoiesis.

    Where does space begin? How far is the Moon? How far is Mars? How does our dynamic star, the Sun, affect its family of planets? All of these questions relate to exploration of our Solar System, and are also part of the Education/Public Outreach (E/PO) Program for NASA’s CINDI project, a space weather mission of opportunity. The Coupled Ion Neutral Dynamics Investigation has been flying aboard the US Air Force Communication/Navigation Outage Forecast System (C/NOFS) satellite in the upper atmosphere of the Earth since April 2008. The Earth’s ionosphere, the part of the atmosphere CINDI studies, is also in space. The CINDI E/PO program uses this fact in lessons designed to help students in middle schools and introductory astronomy classes develop a sense of their place in space. In the activity "How High is Space?" students’ start by building an 8-page scale model of the Earth’s atmosphere with 100 km/page. The peak of Mount Everest, commercial airplanes, and the tops of thunderheads all appear at the bottom of the first page of the model, with astronaut altitude -where space begins- at the top of the same sheet of paper. In "Where Would CINDI Be?" the idea of scale is further developed by modeling the Earth-Moon system to scale first in size, then in distance, using half of standard containers of play dough. With a lowest altitude of about 400 km, similar to that of the International Space Station and orbiting Space Shuttle, CINDI is close to the Earth when compared with the nearly thousand times greater distance to the Moon. Comparing and combining the atmosphere and Earth-Moon system models help reinforce ideas of scale and build student understanding of how far away the Moon actually is. These scale models have also been adapted for use in Family Science Nights, and to include the planet Mars. In this presentation, we will show how we use CINDI’s scale modeling activities and others from our broader space sciences E/PO program in formal and informal

    Tofacitinib is an oral Janus kinase inhibitor that is effective for the treatment of rheumatoid arthritis and shows encouraging therapeutic effects in several other autoimmune diseases. A prominent adverse effect of tofacitinib therapy is the increased risk of viral infections. Despite its advanced stage of clinical development, the modes of action that mediate the beneficial and adverse effects of tofacitinib in autoimmune diseases remain unclear. Interferon alfa (IFNα) produced by plasmacytoid dendritic cells (PDCs) is critically involved in the pathogenesis of many systemic autoimmune diseases and in immunity to viral infections. Using in vitro culture models with human cells, we studied the effects of tofacitinib on PDC survival and IFNα production, and on arthrogenic and antiviral effects of IFNα. Tofacitinib inhibited the expression of antiapoptotic BCL-A1 and BCL-XL in human PDC and induced PDC apoptosis. TLR7 stimulation upregulated the levels of antiapoptotic Bcl-2 family members and prevented the induction of PDC apoptosis by tofacitinib. However, tofacitinib robustly inhibited the production of IFNα by toll like receptor-stimulated PDC. In addition, tofacitinib profoundly suppressed IFNα-induced upregulation of TLR3 on synovial fibroblasts, thereby inhibiting their cytokine and protease production in response to TLR3 ligation. Finally, tofacitinib counteracted the suppressive effects of IFNα on viral replication. Tofacitinib inhibits PDC survival and IFNα production and suppresses arthrogenic and antiviral effects of IFNα signaling. Inhibition of the IFNα pathway at 2 levels may contribute to the beneficial effects of tofacitinib in autoimmune diseases and explain the increased viral infection rates observed during tofacitinib treatment.

    Full Text Available Ayse Seyhan, Baris AtaDivision of Reproductive Endocrinology and Infertility, Department of Obstetrics and Gynecology, McGill University, Montreal, QC, CanadaAbstract: Corifollitropin alfa is a synthetic recombinant follicle-stimulating hormone (rFSH molecule containing a hybrid beta subunit, which provides a plasma half-life of ∼65 hours while maintaining its pharmocodynamic activity. A single injection of corifollitropin alfa can replace daily FSH injections for the first week of ovarian stimulation for in vitro fertilization. Stimulation can be continued with daily FSH injections if the need arises. To date, more than 2500 anticipated normoresponder women have participated in clinical trials with corifollitropin alfa. It is noteworthy that one-third of women did not require additional gonadotropin injections and reached human chorionic gonadotropin criterion on day 8. The optimal corifollitropin dose has been calculated to be 100 µg for women with a body weight ≤ 60 kg and 150 µg for women with a body weight >60 kg, respectively. Combination of corifollitropin with daily gonadotropin-releasing hormone antagonist injections starting on stimulation day 5 seems to yield similar or significantly higher numbers of oocytes and good quality embryos, as well as similar ongoing pregnancy rates compared with women stimulated with daily rFSH injections. Stimulation characteristics, embryology, and clinical outcomes seem consistent with repeated corifollitropin-stimulated assisted reproductive technologies cycles. Multiple pregnancy or ovarian hyperstimulation syndrome rates with corifollitropin were not increased over daily FSH regimen. The corifollitropin alfa molecule does not seem to be immunogenic and does not induce neutralizing antibody formation. Drug hypersensitivity and injection-site reactions are not increased. Incidence and nature of adverse events and serious adverse events are similar to daily FSH injections. Current trials do not

    A randomized, double-blind, multinational, phase 3 study was conducted comparing the efficacy and safety of peginterferon lambda-1a (Lambda)/ribavirin (RBV)/telaprevir (TVR) vs. peginterferon alfa-2a (Alfa)/RBV/TVR in patients with chronic hepatitis C virus (HCV) genotype-1 (GT-1) infection. Patients (treatment-naïve or relapsers on prior Alfa/RBV treatment) were randomly assigned in a 2:1 ratio to receive Lambda/RBV/TVR or Alfa/RBV/TVR. Total duration of treatment was either 24 or 48 weeks (response-guided treatment), with TVR administered for the first 12 weeks. The primary endpoint was the proportion of patients who achieved a sustained virologic response at post treatment week 12 (SVR12), which was tested for noninferiority of Lambda/RBV/TVR. A total of 838 patients were enrolled, and 617 were treated; 411 and 206 patients received Lambda/RBV/TVR and Alfa/RBV/TVR, respectively. The majority of patients were treatment-naïve, with HCV GT-1b and a high baseline viral load (≥800,000 IU/mL). Less than 10% of patients had cirrhosis (Lambda, 7.5%; Alfa, 6.8%). Lambda/RBV/TVR did not meet the criterion for noninferiority (lower bound of the treatment difference interval was -12.3%); the SVR12 in all patients (modified intent-to-treat) was 76.2% in the Lambda arm and 82.0% in the Alfa arm. Overall, the frequency of adverse events in each arm was comparable (Lambda, 91.7%; Alfa, 97.1%). As expected based on the safety profile of the 2 interferons, there were more hepatobiliary events observed in the Lambda arm and more hematologic events in the Alfa arm. In this comparison of Lambda/RBV/TVR and Alfa/RBV/TVR in patients who were treatment-naïve or had relapsed on prior Alfa/RBV treatment, Lambda failed to demonstrate noninferiority based on SVR12 results. Treatment with Lambda/RBV/TVR was associated with a higher incidence of relapse. More patients discontinued Lambda/RBV/TVR treatment during the first 4 weeks of study treatment, mainly due to hepatobiliary

    The study objective was to compare the efficacy and safety of peginterferon lambda-1a combined with ribavirin/daclatasvir (Lambda/RBV/DCV), versus peginterferon alfa-2a combined with ribavirin/telaprevir (Alfa/RBV/TVR), in patients chronically infected with hepatitis C virus (HCV), genotype 1b. This was a prospective, randomized, open-label, phase 3 study (NCT01718158) in adults (aged ≥18 years) who were treatment naïve or prior relapsers to peginterferon alfa/ribavirin therapy. The primary endpoint was sustained virologic response at post-treatment follow-up week 12 (SVR12). Patients were randomized in a 2:1 ratio to receive 24 weeks of Lambda/RBV/DCV or response-guided 24 or 48 weeks of Alfa/RBV/TVR. Overall, 440 patients were treated (294 with Lambda/RBV/DCV; 146 with Alfa/RBV/TVR). The proportion of patients achieving SVR12 was 88.8% in the Lambda/RBV/DCV arm and 70.5% in the Alfa/RBV/TVR arm (difference between arms: 18.3%; 95% confidence interval: 9.9-25.7; P Lambda/RBV/DCV group had fewer rash-related adverse events (AEs), cytopenic abnormalities, flu-like symptoms, serious AEs, and discontinuations due to AEs, but more liver abnormalities than those in the Alfa/RBV/TVR group. In conclusion, treatment with Lambda/RBV/DCV led to higher SVR12 rates and a more favorable safety profile than Alfa/RBV/TVR in patients with chronic HCV, genotype 1b infection.

    Full Text Available Abstract Background Self-administration of recombinant human follicle-stimulating hormone (r-hFSH can be performed using injection pen devices by women undergoing assisted reproductive technology procedures. The objective of this study was to explore the use of the prefilled follitropin alfa pen in routine assisted reproductive technology procedures in Germany. Methods This prospective, observational study was conducted across 43 German IVF centres over a period of 1.75 years. Patients who had used the prefilled follitropin alfa pen in the current or a previous cycle of controlled ovarian stimulation completed a questionnaire to assess their opinions of the device. Results A total of 5328 patients were included in the study. Of these, 2888 reported that they had previous experience of daily FSH injections. Significantly more patients reported that less training was required to use the prefilled follitropin alfa pen than a syringe and lyophilized powder (1997/3081 [64.8%]; p Conclusions In this questionnaire-based survey, routine use of the prefilled follitropin alfa pen was well accepted and associated with favourable patient perceptions. Users of the pen found it easier to initially learn how to use, and subsequently use, than other injection methods. In general, the prefilled follitropin alfa pen was the preferred method for self-administration of gonadotrophins. Together with previous findings, the results here indicate a high level of patient satisfaction among users of the prefilled follitropin alfa pen for daily self-administration of r-hFSH.

    WIN-R (Weight-based dosing of pegINterferon alfa-2b and Ribavirin) was a multicenter, randomized, open-label, investigator-initiated trial involving 236 community and academic sites in the United States, comparing response to pegylated interferon (PEG-IFN) alfa-2b plus a flat or weight-based dose of ribavirin (RBV) in treatment-naive patients with chronic hepatitis C and compensated liver disease. Patients were randomized to receive PEG-IFN alfa-2b at 1.5 microg/kg/week plus flat-dose (800 mg/day) or weight-based-dose RBV (800 mg/day for weight 85-105 kg, or 1400 mg/day for >105- or =65 kg was the primary end point. Low SVR rates have been reported among African American individuals, in whom there is a preponderance of HCV genotype 1. This subanalysis of WIN-R was conducted to evaluate the efficacy of weight-based dosing among African American individuals with genotype 1 infection enrolled in the trial. Of 362 African American patients in the primary efficacy analysis, 188 received RBV flat dosing and 174 received weight-based dosing. SVR rates were higher (21% versus 10%; P = 0.0006) and relapse rates were lower (22% versus 30%) in the weight-based-dose group than in the flat-dose group. Safety and rates of drug discontinuation were similar between the 2 groups. Weight-based dosing of RBV is more effective than flat dosing in combination with PEG-IFN alfa-2b in African American individuals with HCV genotype 1. Even with weight-based dosing, response rates in African American individuals are lower than reported in other ethnic groups.

    2009-02-01

    Full Text Available Abstract Background Lactic acid bacteria of the genus Lactobacillus and Bifidobacterium are one of the most important health promoting groups of the human intestinal microbiota. Their protective role within the gut consists in out competing invading pathogens for ecological niches and metabolic substrates. Among the features necessary to provide health benefits, commensal microorganisms must have the ability to adhere to human intestinal cells and consequently to colonize the gut. Studies on mechanisms mediating adhesion of lactobacilli to human intestinal cells showed that factors involved in the interaction vary mostly among different species and strains, mainly regarding interaction between bacterial adhesins and extracellular matrix or mucus proteins. We have investigated the adhesive properties of Lactobacillus plantarum, a member of the human microbiota of healthy individuals. Results We show the identification of a Lactobacillus plantarum LM3 cell surface protein (48 kDa, which specifically binds to human fibronectin (Fn, an extracellular matrix protein. By means of mass spectrometric analysis this protein was identified as the product of the L. plantarum enoA1 gene, coding the EnoA1 alfa-enolase. Surface localization of EnoA1 was proved by immune electron microscopy. In the mutant strain LM3-CC1, carrying the enoA1 null mutation, the 48 kDa adhesin was not anymore detectable neither by anti-enolase Western blot nor by Fn-overlay immunoblotting assay. Moreover, by an adhesion assay we show that LM3-CC1 cells bind to fibronectin-coated surfaces less efficiently than wild type cells, thus demonstrating the significance of the surface displaced EnoA1 protein for the L. plantarum LM3 adhesion to fibronectin. Conclusion Adhesion to host tissues represents a crucial early step in the colonization process of either pathogens or commensal bacteria. We demonstrated the involvement of the L. plantarum Eno A1 alfa-enolase in Fn-binding, by studying

    2017-04-01

    The European volcanological community contributes to implementation of European Plate Observing System (EPOS) by making operational an integrated platform to guarantee a seamless access to the data provided by the European Solid Earth communities. To achieve this objective, the Volcano Observations Work Package (WP11) will implement a Thematic Core Services (TCS) which is planned to give access to the data and services provided by the European Volcano Observatories (VO) and some Volcanological Research Institutions (VRI; as university departments, laboratories, etc.); both types are considered as national research infrastructures (RI) over which to build the TCS. Currently, the networks on European volcanoes consist of thousands of stations or sites where volcanological parameters are continuously or periodically measured. These sites are equipped with instruments for geophysical (seismic, geodetic, gravimetric, electromagnetic), geochemical (volcanic plumes, fumaroles, groundwater, rivers, soils), environmental observations (e.g. meteorological and air quality parameters), as well as various prototypal monitoring systems (e.g. Doppler radars, ground based SAR). In Europe also operate laboratories for sample analysis (rocks, gases, isotopes, etc.), and almost continuous analysis of space-borne data (SAR, thermal imagery, SO2 and ash), as well as high-performance computing centres. All these RIs provide high-quality information (observations) on the current status of European volcanoes and the geodynamic background of the surrounding areas. The implementation of the Volcano Observations TCS is addressing technical and management issues, both considering the current heterogeneous state of the art of the volcanological research infrastructures in Europe. Indeed, the frame of the VO and VRI is now too fragmented to be considered as a unique distributed infrastructure, thus the main effort planned in the frame of the EPOS-IP is focused to create services aimed at

    Turoctocog alfa (NovoEight(®)) is a human recombinant coagulation factor VIII (rFVIII) for the treatment of patients with hemophilia A. To evaluate the pharmacokinetics of turoctocog alfa in all age groups across clinical trials. Data from previously treated patients with severe hemophilia A (FVIII activity level of ≤ 1%) with no history of FVIII inhibitors, in a non-bleeding state, were included. The pharmacokinetics were assessed following a wash-out period and a subsequent single intravenous 50 IU kg(-1) dose of turoctocog alfa. Blood was sampled during a 48-h period postdose. Standard pharmacokinetic (PK) parameters were estimated on the basis of plasma FVIII activity vs. time (PK profiles) with non-compartmental methods. Furthermore, a population PK analysis was conducted. Data from 76 patients (aged 1-60 years) enrolled globally across six clinical trials were included, totaling 105 turoctocog alfa PK profiles. Single-dose PK results 3-6 months after the first dose of turoctocog alfa were comparable with the results obtained after the first dose. Similar PK characteristics were shown for different lots and strengths of the drug product. Overall, area under the plasma concentration (activity) curve from administration to infinity (AUC) and t1(/2) tended to increase with increasing age, with lower AUC and shorter t(1/2) being seen in children than in adolescents and adults. The PK profiles of turoctocog alfa and other commercially available plasma-derived FVIII and rFVIII products were similar in all age groups. The PK characteristics of turoctocog alfa have been thoroughly studied, and shown to be consistent over time, reproducible between different lots and strengths of drug product, and similar to those observed for other FVIII products. © 2014 International Society on Thrombosis and Haemostasis.

    Three educational experiences are presented in this paper on the development of national and regional networks to incorporate renewable energy in curricular programmes. IASEE-Argentina, established in 1990 as the National Section of IASEE, the International Association for Solar Energy Education, was designated in 1993 as the Education Working Group of ASADES, the Argentine Association of Solar Energy. It holds annual meetings to coincide with the ASADES conference. Arquisur is a regional network established by Architectural Faculties of State Universities within the Mercosur Region, covering Argentina, southern Brazil, Paraguay and Uruguay, to promote exchange and development between the 19 faculties involved. A Working Group set up by Arquisur with members from four countries developed the programme for short post-graduate courses on bioclimatic design and rational energy use in buildings, which has been given in Argentina and Uruguay. Alfa-Built, a project supported by the European Union for promoting academic exchange in the field of energy efficient building is also introduced. This paper presents the development and initial results of these educational experiences. (author)

    We studied 13 patients with chronic myeloid leukemia and autoimmune hemolytic anemia induced by interferon alfa. They underwent tests for immune protein detection and characterization of IgG subclasses in RBCs by direct antiglobulin test (PAD) and the microplate technique. Also they were applied ELISA test for quantifying immunoglobulins in the red blood cells. It was detected the presence of IgG and C3 in 53.84 % of cases, IgG alone in 23.07 % and in 15.38 % were identified IgG and IgA autoantibodies. In 11 patients the presence of IgG1 was showed and also in one case the subclass IgG3 autoantibodies was identified. The ELISA detected antibodies at concentrations of 183 IgG molecules per erythrocyte in a patient with negative PAD. In high-grade hemolysis patients, it was found a concentration of autoantibodies between 1 500 and 3 180 molecules of IgG per erythrocyte, while in low-grade hemolysis patients it behaved between 183 and 1 000 molecules. There was a negative correlation between Hb and plasma haptoglobin values with the number of IgG molecules per erythrocyte and a positive correlation between the latter with the reticulocyte count

    Two patients experienced episodes of acute pancreatitis shortly after starting treatment with interferon alfa-2b (IFN-alpha) for a chronic hepatitis C infection. The first patient was a 40-year-old man who developed acute pancreatitis after 15 weeks of treatment with 3 MU IFN-alpha subcutaneously (SC) 3 times weekly and 1200 mg ribavirin. After disappearance of symptoms and normalization of laboratory values, oral intake of solid foods and IFN-alpha therapy were restarted. Within hours, a relapse of acute pancreatitis occurred. A rechallenge with IFN-alpha 4 days later was followed by a prompt increase in serum lipase level, and IFN-alpha therapy was discontinued. The second patient was a 38-year-old man who developed acute pancreatitis 2 hours after SC administration of 5 MU IFN-alpha. Ultrasound endoscopy showed sludge in the gallbladder. The patient was rechallenged 5 weeks later with 3 MU IFN-alpha SC. Although serum amylase and lipase levels increased after readministration of IFN-alpha, treatment was continued. The patient was readmitted 2 weeks later with severe abdominal pain, and IFN-alpha administration was discontinued. Considering the temporal relationship between the start of IFN-alpha treatment and development of acute pancreatitis, the absence of other clear etiologic factors for acute pancreatitis, disappearance of symptoms after discontinuation of IFN-alpha, and positive reactions to rechallenge, IFN-alpha is the most probable cause for development of acute pancreatitis in these patients.

  4. LHC Report: special run with de-squeezed beams for ATLAS/ALFA and TOTEM

    Helmut Burkhardt for the LHC team

    2015-01-01

    The main high-luminosity proton-proton run of the LHC is complemented by one week per year of special proton-proton runs. The special runs are performed with larger beam sizes at the interaction points to allow the forward physics experiments, TOTEM and ATLAS/ALFA, the chance to make precise measurements of protons as they emerge from collisions at small angles.   In standard high-luminosity operation, the beams are squeezed to give small beam sizes at the interaction points to maximise the collision rates. The “squeeze” takes place at top energy and the beam size at the centre of ATLAS (IP1) and CMS (IP5) is reduced from 66 micrometres at the top of the ramp to 18 micrometres before colliding beams are established. Protons that avoid the fate of an inelastic collision but yet still interact – in elastic or diffractive events – are scattered and emerge in the forward direction. The reduction in beam size has a side effect of increasing the an...

Specific antidotes to NOACs are under development. Idarucizumab (aDabi-Fab, BI 655075 is a novel humanized mouse monoclonal antibody that binds dabigatran and reverses its anticoagulant effect. In a recent Phase III study (Reversal Effects of Idarucizumab on Active Dabigatran, a 5 g intravenous infusion of idarucizumab resulted in the normalization of dilute thrombin time in 98% and 93% of the two groups studied, with normalization of ecarin-clotting time in 89% and 88% patients. Two other antidotes, andexanet alfa (PRT064445 and ciraparantag (PER977 are also under development for reversal of NOACs. In this review, we discuss commonly encountered management issues with NOACs such as periprocedural management, laboratory monitoring of anticoagulation, and management of bleeding. We review currently available data regarding specific antidotes to NOACs with respect to pharmacology and clinical trials.Keywords: novel oral anticoagulant, dabigatran, idarucizumab, reversal

    2015-12-01

    Increasingly, geographically diverse organizations, like NASA's Science Mission Directorate Education and Public Outreach personnel (SMD EPO), are looking for ways to facilitate group interactions in meaningful ways while limiting costs. Towards this end, of particular interest, and showing great potential are communities of practice. Communities of practice represent relationships in real-time between and among people sharing a common practice. They facilitate the sharing of information, building collective knowledge, and growing of the principles of practice. In 2010-11, SMD EPO established a website to support EPO professionals, facilitate headquarters reporting, and foster a community of practice. The purpose of this evaluation is to examine the design and use of the workspace and the value created for both individual community members and SMD EPO, the sponsoring organization. The online workspace was launched in 2010-11 for the members of NASA's SMDEPO community. The online workspace was designed to help facilitate the efficient sharing of information, be a central repository for resources, help facilitate and support knowledge creation, and ultimately lead to the development of an online community of practice. This study examines the role of the online workspace component of a community in the work of a community of practice. Much has been studied revealing the importance of communities of practice to organizations, project success, and knowledge management and some of these same successes hold true for virtual communities of practice. Additionally, we look at the outcomes of housting the online community for these past years in respect to knowledge building and personal and organizational value, the affects on professional dvelopment opportunities, how community members have benefited, and how the workspace has evolved to better serve the community.

    Local creativity and artistry is a powerful resource that enhances education programs and helps us generate excitement for science within our communities. In celebration of the 2016 Solar Eclipse, the National Solar Observatory (NSO) and its Daniel K Inouye Solar Telescope (DKIST) project were pleased to engage with students across Maui County, Hawai`i, via the 2016 Maui Eclipse Art Contest. With the help of the Maui Economic Development Board and the University of Hawai'is Institute for Astronomy, we solicited art entries from all K-12 schools in Maui County approximately 6 months prior to the eclipse. Along with divisional prizes, a grand prize was selected by a panel of local judges, which was subsequently printed on 25,000 solar eclipse viewing glasses and distributed to all Maui students. We found that the impact of a locally-sourced glasses design cannot be understated. Overall, the success of this program relied upon reaching out to individual teachers, supplying educational flyers to all schools, and visiting classrooms. On the day of the eclipse, all of the art entries were prominently displayed during a community eclipse viewing event at Kalama Beach Park in Kihei, HI, that was co-hosted by NSO and the Maui Science Center. This eclipse art contest was integral to making local connections to help promote science education on Maui, and we suggest that it could be adapted to the solar community's EPO activities for the upcoming 2017 Great American Solar Eclipse.

    Presence of autoantibodies to alfa-fodrin was investigated in patients with Sjögren's syndrome (n = 61), Hashimoto thyroiditis (n = 27), Sjögren's syndrome associated with Hashimoto thyroiditis (n = 31) and in healthy persons (n = 77). In each group, level of alfa-fodrin antibodies was higher than in the controls. There was no significant difference in their presence either between patients with Hashimoto thyroiditis with or without Sjögren's syndrome, or-in IgA isotype-between Sjögren's and Hashimoto thyroiditis patients. Correlation was found between the level of IgG alfa-fodrin and anti-thyroglobulin antibodies. Based on these findings, fodrin can be associated with both endocrine and exocrine glandular secretion. Antibodies to alfa-fodrin might have a role in the pathogenesis of Hashimoto thyroiditis concerning the "final common effectory pathway", secretion. Alfa-fodrin antibodies can be good markers of secretory disorders. Assessment of these autoantibodies might help the diagnosis and follow-up of patients with impaired secretory capability of not only autoimmune origin.

    Full Text Available Background: Despite the availability of a  large number of treatments for multiple sclerosis with various targets, these treatments are not always effective. According to the literature, experimental studies have shown a  significant decrease in tumor necrosis factor alfa (TNF-α with the use of extracorporeal photochemotherapy. Aim: To assess changes in TNF-α in patients with multiple sclerosis during treatment with transimmunization. Materials and methods: The study recruited 13 adult patients with multiple sclerosis. Serum TNF-α was measured by immunochemiluminescence analysis (IMMULITE 1000, Siemens. The patients were treated by transimmunization, i.e. a  modified photopheresis. Two hours before the procedure, Ammifurin (8-methoxypsoralene was administered to all the patients, then their mononuclear cells were isolated under PBSC protocol with Haemonetics MCS+ cell separator. Thereafter, mononuclear cells were irradiated with ultraviolet for 90  minutes and incubated for 20 hours at 37 °С. The next day the cells were re-infused to the patients. The procedure was performed 2  times per week for 6  months, then once per 4  months. Results: Before transimmunization, mean TNF-α level in adult patients with multiple sclerosis was 9.958±0.812  pg/mL (normal, below 8.1 pg/mL. After transimmunization, its level was 6.992±0.367  pg/mL (р<0.05. Conclusion: Ultraviolet irradiation of peripheral blood monocytes with their subsequent incubation (transimmunization led to a 30% decrease of serum TNF-α in patients with multiple sclerosis. This indicates a suppressive effect of transimmunization on TNF-α. Hence, in patients with multiple sclerosis transimmunization exerts an anti-inflammatory effect.

    Introduction Increasing use of factor Xa (FXa) inhibitors necessitates effective reversal agents to manage bleeding. Andexanet alfa, a novel modified recombinant human FXa, rapidly reverses the anticoagulation effects of direct and indirect FXa inhibitors. Objective To evaluate the ability of andexanet to reverse anticoagulation in vitro and reduce bleeding in rabbits administered edoxaban. Materials and methods In vitro studies characterized the interaction of andexanet with edoxaban and its ability to reverse edoxaban-mediated anti-FXa activity. In a rabbit model of surgically induced, acute hemorrhage, animals received edoxaban vehicle+andexanet vehicle (control), edoxaban (1 mg/kg)+andexanet vehicle, edoxaban+andexanet (75 mg, 5-minute infusion, 20 minutes after edoxaban), or edoxaban vehicle+andexanet prior to injury. Results Andexanet bound edoxaban with high affinity similar to FXa. Andexanet rapidly and dose-dependently reversed the effects of edoxaban on FXa activity and coagulation pharmacodynamic parameters in vitro. In edoxaban-anticoagulated rabbits, andexanet reduced anti-FXa activity by 82% (from 548±87 to 100±41 ng/ml; P<0.0001), mean unbound edoxaban plasma concentration by ~80% (from 100±10 to 21±6 ng/ml; P<0.0001), and blood loss by 80% vs. vehicle (adjusted for control, 2.6 vs. 12.9 g; P = 0.003). The reduction in blood loss correlated with the decrease in anti-FXa activity (r = 0.6993, P<0.0001) and unbound edoxaban (r = 0.5951, P = 0.0035). Conclusion These data demonstrate that andexanet rapidly reversed the anticoagulant effects of edoxaban, suggesting it could be clinically valuable for the management of acute and surgery-related bleeding. Correlation of blood loss with anti-FXa activity supports the use of anti-FXa activity as a biomarker for assessing anticoagulation reversal in clinical trials. PMID:29590221

    To evaluate the cost-effectiveness of dibotermin alfa compared with autologous iliac crest bone graft (ICBG) for patients undergoing single level lumbar interbody spinal fusion in a UK hospital setting. An individual patient data (IPD) meta-analysis of six randomized controlled clinical trials and two single arm trials compared dibotermin alfa on an absorbable collagen implantation matrix (ACIM) (n = 456) and ICBG (n = 244) on resource use, re-operation rates, and SF-6D (Short form 6-dimension) health utility (total N = 700). Failure-related second surgery, operating time, post-operative hospital stay, and quality-adjusted life years (QALYs) derived from the IPD meta-analysis were included as inputs in an economic evaluation undertaken to assess the cost-effectiveness of dibotermin alfa/ACIM versus ICBG for patients undergoing single level lumbar interbody spinal fusion. A four year time horizon and the United Kingdom (UK) National Health Service (NHS) and Personal Social Services (PSS) perspective was adopted in the base case, with sensitivity analyses performed to gauge parameter uncertainty. In the base case analysis, patients treated using dibotermin alfa/ACIM (12 mg pack) accrued 0.055 incremental QALYs at an incremental cost of £ 737, compared with patients treated with ICBG. This resulted in an incremental cost-effectiveness ratio (ICER) of £ 13,523, indicating that at a willingness-to-pay threshold of £ 20,000, dibotermin alfa/ACIM is a cost-effective intervention relative to ICBG from the NHS and PSS perspective. In a UK hospital setting, dibotermin alfa/ACIM is a cost-effective substitute for ICBG for patients who require lumbar interbody arthrodesis.

    Full Text Available Background/Purpose: The long-acting corifollitropin alfa is comparable to FSH in terms of pregnancy outcomes in normal responders and poor responders. Corifollitropin alfa has never been studied in polycystic ovary syndrome (PCOS patients because of concerns of excessive ovarian stimulation and ovarian hyperstimulation syndrome (OHSS. The purpose of the study was to evaluate if corifollitropin alfa can be used in PCOS patients. Methods: Forty PCOS patients who were going to undergo in vitro fertilization were enrolled in this study. A single injection of corifollitropin alfa was administered on cycle day 2 or day 3. From stimulation day 8 onwards, daily FSH was administered until the day of final oocyte maturation. Cetrorelix was administered from stimulation day 5 to prevent premature LH surge. Final oocyte maturation was triggered by: acetate. All embryos were cryopreserved and replaced in subsequent cycles. Results: All 40 patients were subjected to oocyte retrieval, and none developed moderate or severe ovarian hyperstimulation syndrome (0%, 95% CI 0–0.088. For each patient, an average of 23.4 (±7.4; 95% CI 21.0–25.7 oocytes were retrieved and a mean of 11.7 (±6.4; 95% CI 9.6–13.8 embryos were frozen. Mean serum estradiol level on the day of GnRHa triggering was 7829.9 pg/ml (±3297; 95% CI 6775–8885. The cumulated ongoing pregnancy rate after 3 frozen-thawed embryo transfers was 75.0% (95% CI 61.6%–88.4%. Conclusion: The results suggest that corifollitropin alfa/GnRH antagonist protocol can be used in PCOS patients, in combination with GnRHa triggering and embryo cryopreservation.

Walaupun assumsi yang berkembang itu dapat dimaklumi, namun keyakinan tersebut tentu saja tidak sepenuhnya benar. Karena meskipun terdapat sekelompok orang Islam yang berbuat radikal, akan tetapi mayoritas Muslim justru bertentangan dengan mereka. Lagi pula, jika dicermati secara mendalam, sesungguhnya Islam sama sekali tidak mentolerir tindakan radikal. Ia adalah agama kasih sayang yang sangat mendodrong penganutnya untuk berbuat baik terhadap orang lain, termasuk kepada orang-orang non-Muslim. Artikel ini menawarkan beberapa upaya strategis dalam mengantisipasi dan menanggulangi bahaya radikalisme-terorisme.

    Background Peginterferon alfa-2a (40 kDa) is currently administered using a prefilled syringe. The peginterferon alfa-2a disposable autoinjector is a new safety-engineered device designed to facilitate injection and reduce the risk of needlestick injuries. The analysis of two open-label Phase I trials evaluated the pharmacokinetics, successful administration, and tolerability of peginterferon alfa-2a when using the autoinjector. The studies were performed to support the filing and registration of the autoinjector device. Methods In trial 1, 50 healthy adult subjects received one 180 μg dose of peginterferon alfa-2a via the autoinjector. Serial blood samples were collected predose, up to 336 hours following drug administration, and at follow-up (28 ± 3 days post-dosing) for noncompartmental pharmacokinetic analysis. Trial 2 randomized 60 adult patients with chronic hepatitis C to 180 μg peginterferon alfa-2a once weekly by the autoinjector or prefilled syringe for 3 weeks followed by the alternative device (prefilled syringe or autoinjector, respectively) for 3 weeks. Patients also received ribavirin. Administration by the devices was evaluated under direct observation by a study staff member and by patient subjective assessment. Results In trial 1, following a single dose of peginterferon alfa-2a, the maximum plasma concentration was 16.1 ± 5.3 ng/mL (mean ± standard deviation), and area under the concentration time curve (0–168 hours) was 1996 ± 613 ng · hour/mL, similar to that reported using a vial/syringe or prefilled syringe. In trial 2, few patients showed handling difficulties with either device. Generally, patients were observed to be more satisfied and confident, followed instructions better, and successfully initiated injection with the autoinjector versus the prefilled syringe. Patients reported the autoinjector to be more convenient and easier to use. No pain or discomfort was experienced using the autoinjector. The autoinjector safety profile

    Full Text Available Correlations between angiotensin-converting enzyme (ACE genotype (I/I, I/D, D/D, disease severity at baseline and response to enzyme replacement therapy (ERT were assessed in the Pompe disease Late-Onset Treatment Study (LOTS. No correlations were observed between ACE genotype and disease severity at baseline. However, D/D patients appeared to have a reduced response to alglucosidase alfa treatment than I/I or I/D patients, suggesting that ACE polymorphisms may influence the response to alglucosidase alfa treatment and warrants further investigation.

    Pegylated interferon-lambda-1a (Lambda), a type III interferon (IFN) in clinical development for the treatment of chronic HCV infection, has shown comparable efficacy and an improved safety profile to a regimen based on pegylated IFN alfa-2a (alfa). To establish a mechanistic context for this improved profile, we investigated the ex vivo effects of Lambda and alfa on cytokine and chemokine release, and on expression of IFN-stimulated genes (ISGs) in primary human hepatocytes and peripheral blood mononuclear cells (PBMCs) from healthy subjects. Our findings were further compared with changes observed in blood analysed from HCV-infected patients treated with Lambda or alfa in clinical studies. mRNA transcript and protein expression of the IFN-λ-limiting receptor subunit was lower compared with IFN-α receptor subunits in all cell types. Upon stimulation, alfa and Lambda induced ISG expression in hepatocytes and PBMCs, although in PBMCs Lambda-induced ISG expression was modest. Furthermore, alfa and Lambda induced release of cytokines and chemokines from hepatocytes and PBMCs, although differences in their kinetics of induction were observed. In HCV-infected patients, alfa treatment induced ISG expression in whole blood after single and repeat dosing. Lambda treatment induced modest ISG expression after single dosing and showed no induction after repeat dosing. Alfa and Lambda treatment increased IP-10, iTAC, IL-6, MCP-1 and MIP-1β levels in serum, with alfa inducing higher levels of all mediators compared with Lambda. Overall, ex vivo and in vivo induction profiles reported in this analysis strongly correlate with clinical observations of fewer related adverse events for Lambda vs those typically associated with alfa. © 2014 John Wiley & Sons Ltd.

    The Pulsar Arecibo L-band Feed Array (PALFA) Survey uses the ALFA 7-beam receiver to search both inner and outer Galactic sectors visible from Arecibo (32° ≲ ℓ ≲ 77° and 168° ≲ ℓ ≲ 214°) close to the Galactic plane (|b| ≲ 5°) for pulsars. The PALFA survey is sensitive to sources fainter and more distant than have previously been seen because of Arecibo's unrivaled sensitivity. In this paper we detail a precursor survey of this region with PALFA, which observed a subset of the full region (slightly more restrictive in ℓ and |b| ≲ 1°) and detected 45 pulsars. Detections included 1 known millisecond pulsar and 11 previously unknown, long-period pulsars. In the surveyed part of the sky that overlaps with the Parkes Multibeam Pulsar Survey (36° ≲ ℓ ≲ 50°), PALFA is probing deeper than the Parkes survey, with four discoveries in this region. For both Galactic millisecond and normal pulsar populations, we compare the survey's detections with simulations to model these populations and, in particular, to estimate the number of observable pulsars in the Galaxy. We place 95% confidence intervals of 82,000 to 143,000 on the number of detectable normal pulsars and 9000 to 100,000 on the number of detectable millisecond pulsars in the Galactic disk. These are consistent with previous estimates. Given the most likely population size in each case (107,000 and 15,000 for normal and millisecond pulsars, respectively), we extend survey detection simulations to predict that, when complete, the full PALFA survey should have detected 1000{sub −230}{sup +330} normal pulsars and 30{sub −20}{sup +200} millisecond pulsars. Identical estimation techniques predict that 490{sub −115}{sup +160} normal pulsars and 12{sub −5}{sup +70} millisecond pulsars would be detected by the beginning of 2014; at the time, the PALFA survey had detected 283 normal pulsars and 31 millisecond pulsars, respectively. We attribute the deficiency in normal pulsar

A single electro-gene transfer of an RNA- and codon-optimized mEPOopt gene into skeletal muscle resulted in a 3- to 4-fold increase of mEPO production sustained for >1 year and triggered a significant increase in hematocrit and hemoglobin without causing adverse effects. mEPO expression and hematologic levels were significantly lower when using comparable amounts of the wild type (mEPOwt) gene and only marginal effects were induced by mEPOΔCpG lacking intragenic CpG dinucleotides, even at high pDNA amounts. Corresponding with these observations, in vitro analysis of transfected cells revealed a 2- to 3-fold increased (mEPOopt) and 50% decreased (mEPOΔCpG) erythropoietin expression compared with mEPOwt, respectively. RNA analyses demonstrated that the specific design of the transgene sequence influenced expression levels by modulating transcriptional activity and nuclear plus cytoplasmic RNA amounts rather than translation. In sum, whereas CpG depletion negatively interferes with efficient expression in postmitotic tissues, mEPOopt doses <0.5 μg were sufficient to trigger optimal long-term hematologic effects encouraging the use of sequence-optimized transgenes to further reduce effective pDNA amounts.

    Full Text Available Enzyme replacement therapy (ERT with elosulfase alfa is the only approved therapy in Japan for patients with Morquio A syndrome, a lysosomal storage disorder inherited in an autosomal recessive fashion. The experience with ERT in severely affected, non-ambulatory patients has not been reported in previous studies. This case report describes clinical evidence for the 1-year efficacy and safety of ERT with elosulfase alfa in a severely affected, non-ambulatory, 47-year-old patient with Morquio A syndrome who needs intensive respiratory management. ERT with elosulfase alfa was well tolerated in this patient. Because of the possibility of potential hypersensitivity adverse events, special attention is needed when using ERT in patients with respiratory disorders. However, under the appropriate management of specialists, the patient in this case report showed significant respiratory improvement after starting ERT, and abdominal bloating was improved by gas evacuation. In addition, the patient was able to lift up her arms, reach behind her back, and move her legs slightly, and she recovered her grip strength. Her hearing loss improved and she could hear without a hearing aid. This report shows that ERT with elosulfase alfa can be used with appropriate respiratory care in patients with severe respiratory dysfunction.

    Hypogonadotropic hypogonadism (HH) in men results in insufficient testicular function and deficiencies in testosterone and spermatogenesis. Combinations of human chorionic gonadotropin (hCG) and recombinant follicle-stimulating hormone (recFSH) have been successful in the treatment of HH. Corifollitropin alfa is a long-acting FSH-analog with demonstrated action in women seeking infertility care. The aim of this study was to investigate the efficacy and safety of corifollitropin alfa combined with hCG to increase testicular volume and induce spermatogenesis in men with HH. This was a Phase III, multi-center, open-label, single-arm trial of corifollitropin alfa in azoospermic men aged 18 to 50 years with HH. After 16 weeks of pretreatment of 23 subjects with hCG alone, 18 subjects with normalized testosterone (T) levels who remained azoospermic entered the 52-week combined treatment phase with hCG twice-weekly and 150 μg corifollitropin alfa every other week. The increase in testicular volume (primary efficacy endpoint) and induction of spermatogenesis resulting in a sperm count ≥1 × 10 6 /mL (key secondary efficacy endpoint) during 52 weeks of combined treatment were assessed. Safety was evaluated by the presence of anti-corifollitropin alfa antibodies and the occurrence of adverse events (AEs). Mean (±SD) testicular volume increased from 8.6 (±6.09) mL to 17.8 (±8.93) mL (geometric mean fold increase, 2.30 [95% CI: 2.03, 2.62]); 14 (77.8%) subjects reached a sperm count ≥1 × 10 6 /mL. No subject developed confirmed anti-corifollitropin alfa antibodies during the trial. Treatment was generally well tolerated. Corifollitropin alfa 150 μg administrated every other week combined with twice-weekly hCG for 52 weeks increased testicular volume significantly, and induced spermatogenesis in >75% of men with HH who had remained azoospermic after hCG treatment alone.

    Erythropoiesis-stimulating agents (ESAs) are often used in treatment of patients with chemotherapy-induced anemia. Many studies have demonstrated an improved hemoglobin (Hb) response when ESA is combined with intravenous iron supplementation and a higher effectiveness of intravenous iron over traditional oral iron formulations. A new formulation of oral sucrosomial iron featuring an increased bioavailability compared to traditional oral formulations has recently become available and could provide a valid alternative to those by intravenous (IV) route. Our study evaluated the performance of sucrosomial iron versus intravenous iron in increasing hemoglobin in anemic cancer patients receiving chemotherapy and darbepoetin alfa, as well as safety, need of transfusion, and quality of life (QoL). The present study considered a cohort of 64 patients with chemotherapy-related anemia (Hb >8 g/dL iron deficiency, scheduled to receive chemotherapy and darbepoetin. All patients received darbepoetin alfa 500 mcg once every 3 weeks and were randomly assigned to receive 8 weeks of IV ferric gluconate 125 mg weekly or oral sucrosomial iron 30 mg daily. The primary endpoint was to demonstrate the performance of oral sucrosomial iron in improving Hb response, compared to intravenous iron. The Hb response was defined as the Hb increase ≥2 g/dL from baseline or the attainment Hb ≥ 12 g/dL. There was no difference in the Hb response rate between the two treatment arms. Seventy one percent of patients treated with IV iron achieved an erythropoietic response, compared to 70% of patients treated with oral iron. By conventional criteria, this difference is considered to be not statistically significant. There were also no differences in the proportion of patients requiring red blood cell transfusions and changes in QoL. Sucrosomial oral iron was better tolerated. In cancer patients with chemotherapy-related anemia receiving darbepoetin alfa, sucrosomial oral iron provides

    2008-07-01

    Full Text Available A deficiência de alfa-1 antitripsina é um distúrbio genético de descoberta recente e que ocorre com freqüência comparável à da fibrose cística. Resulta de diferentes mutações no gene SERPINA1 e tem diversas implicações clínicas. A alfa-1 antitripsina é produzida principalmente no fígado e atua como uma antiprotease. Tem como principal função inativar a elastase neutrofílica, impedindo a ocorrência de dano tecidual. A mutação mais freqüentemente relacionada à doença clínica é o alelo Z, que determina polimerização e acúmulo dentro dos hepatócitos. O acúmulo e a conseqüente redução dos níveis séricos de alfa-1 antitripsina determinam, respectivamente, doença hepática e pulmonar, sendo que esta se manifesta principalmente sob a forma de enfisema de aparecimento precoce, habitualmente com predomínio basal. O diagnóstico envolve a detecção de níveis séricos reduzidos de alfa-1 antitripsina e a confirmação fenotípica. Além do tratamento usual para doença pulmonar obstrutiva crônica, existe atualmente uma terapia específica com infusão de concentrados de alfa-1 antitripsina. Essa terapia de reposição, aparentemente segura, ainda não teve a eficácia clínica definitivamente comprovada, e o custo-efetividade também é um tema controverso e ainda pouco abordado. Apesar da sua importância, não existem dados epidemiológicos brasileiros a respeito da prevalência da doença ou da freqüência de ocorrência dos alelos deficientes. O subdiagnóstico também tem sido uma importante limitação tanto para o estudo da doença quanto para o tratamento adequado dos pacientes. Espera-se que a criação do Registro Internacional de Alfa-1 venha a resolver essas e outras importantes questões.Alpha-1 antitrypsin deficiency is a recently identified genetic disease that occurs almost as frequently as cystic fibrosis. It is caused by various mutations in the SERPINA1 gene, and has numerous clinical

    Full Text Available Telinga berdenging atau dikenal dalam bahasa medis sebagai tinitus, banyak dikeluhkan sebagai suatu bising atau bunyi yang muncul di kepala tanpa adanya rangsangan dari luar. Adapun keluhan yang dialami ini seperti bunyi mendengung, mendesis, menderu, atau berbagai variasi bunyi yang lain. Tinitus bukanlah penyakit atau sindroma, tapi hanya merupakan gejala yang mungkin berasal dari satu atau sejumlah kelainan. Sebetulnya suara yang terdengar oleh telinga tersebut belum tentu bersifat kelainan atau patologis. Jika orang sehat yang terbukti telinganya normal, berada dalam ruang kedap (anehoic chamber, maka ia akan dapat mendengar berbagai macam suara yang berasal dari berbagai organ tubuhnya sendiri yang memang bekerja setiap saat, contohnya: pernapasan, kontraksi jantung, dan aliran darah. Kenyataannya, dalam kehidupan sehari-hari, suasana yang memungkinkan suara fisiologis atau normal tersebut terdengar oleh seseorang sangat jarang tercipta dan bahkan dalam kamar yang sunyi di malam hari sekalipun. Hal ini dikarenakan, bunyi masking dari lingkungan dengan berintensitas bunyi sekitar 25 – 30 dB. Tinitus baru menjadi gejala jika suara organ tubuh intensitasnya melebihi bunyi masking lingkungan tadi. Tinitus kerap diderita terutama orang pada kelompok usia pertengahan dan usia tua. Menurut data statistic dari pusat kesehatan di Amerika, sekitar 32% orang dewasa pernah mengalami tinitus pada suatu saat tertentu dalam hidupnya, dan 6 % nya sangat menganggu dan cukup sulit disembuhkan. Di Inggris, 17% populasi juga memiliki masalah tinitus. Sayangnya di Indonesia belum ada data statistic yang memadai, namun berdasarkan pengalaman empiris, penderita tinitus cukup banyak dan sering ditemui di tempat praktek, klinik, maupun rumah sakit. Meski tinitus bukanlah keadaan yang membahayakan, munculnya gejala ini pada hampir kebanyakan orang sangat mengganggu dan sering mempengaruhi kualitas hidup dan pekerjaannya.

    Full Text Available Energi dapat berubah dari satu bentuk ke bentuk yang  lainnya, perubahannya sering mempengaruhi lingkungan dan udara yang kita hirup dengan berbagai cara. Energy kimia dalam bahan bakar fosil diubah menjadi energy panas, mekanik, atau listrik melalui pembakaran dan  ini sebagai penghasil polutan terbesar. Dan dengan demikian pembangkit listrik, kendaraan bermotor, dan kompor adalah penyebab utama terjadinya polusi udara.  Polutan yang dikeluarkan biasanya dikelompokan menjadi  hidrokarbon (HC, nitrogen oksida (NOx, dan  karbon monoksida (CO. Polutan yang dihasilkan pada pembakaran fosil merupakan faktor terbesar terjadinya asap, hujan asam,  pemanasan global dan perubahan iklim.   The conversion of energy from one form to another often affects the environment and the air we breath in many ways. Pollutants are emitted as the chemical energy in fossil fuels is converten to thermal, mechanical, or electrical energy via combustion, and thus power plants, motor vehicles, and even stoves take the blame for air pollution, and  the pollutants released by the vehicles are usually grouped as hydrocarbons (HC, nitrogen oxides (NOx, and carbon monoxide (CO. Pollutans emitted during the combustion of fossil fuels are responsible for smog, acid rain, and global warming and climate change.

    Standards, Options and Recommendations for the use of recombinant erythropoietin (epoietin alpha and beta darbepoietin alpha, EPO) in the management of anaemia in oncology for patient undergoing radiotherapy - UPDATE 2003. Context. - 'The Standards, Options and Recommendations' (SOR) project, started in 1993, is a collaboration between the Federation of French Cancer Centres (FNCLCC), the twenty French cancer centres, and specialists from French public universities, general hospitals and private clinics. The main objective is the development of clinical practice guidelines to improve the quality of health care and the outcome of cancer patients. The methodology is based on a literature review and critical appraisal by a multidisciplinary group of experts, with feedback from specialists in cancer care delivery. Objectives. - To update the Standards, Options and Recommendations clinical practice guidelines for the use of recombinant erythropoietin (epoietin alpha and beta darbepoietin-alpha, EPO) in the management of anaemia in oncology for patient undergoing radiotherapy. Methods. - The working group identified the questions requiring up-dating from the previous guideline. Medline and Embase were searched using specific search strategies from January 1999 to October 2002. Literature monitoring was performed to identify randomized clinical trials published between October 2002 to November 2003. In addition several Internet sites were searched in October 2002. Results. - There is no standard attitude for use of rHuEPO in patients undergoing radiotherapy. There is no evidence to support use of rHuEPO in patients with ENT cancer receiving radiotherapy alone. In patients undergoing curative radiotherapy, it is recommended to correct anaemia under 10 g/dL using transfusion rather than rHuEPO. When the haemoglobin concentration is between 12 g/dL and 14 g/dL initial use of rHuEPO can be an option under certain conditions for radio-chemotherapy if the risk of anaemia is

    This study aimed to compare the outcomes of controlled ovarian stimulation (COS) with corifollitropin alfa versus daily recombinant follicle-stimulating hormone (rRFSH) or highly purified human menopausal gonadotropin (HP-HMG) in patients undergoing in vitro fertilization (IVF) cycles based on gonadotropin-releasing hormone (GnRH) antagonist protocols. The primary endpoints were total number of oocytes and mature oocytes. This retrospective study looked into 132 controlled ovarian stimulation cycles from IVF or oocyte cryopreservation performed in a private human reproduction center between January 1 and December 31, 2014. Enrollment criteria: women aged 0.05). There were no significant differences in fertilization (76.9% vs. 76.8%, p=1.0), biochemical pregnancy (66.7% vs. 47.2%, p=0.1561) or embryo implantation rates (68.7% vs. 50%, p=0.2588) between the groups using corifollitropin alfa and rFSH or HMG, respectively. Corifollitropin alfa seems to be as effective as rFSH or HP-HMG when used in the first seven days of ovulation induction for patients undergoing assisted reproduction in GnRH antagonist protocols.

    Hemophilia A represents up to 80% of all hemophilia cases in China. In patients with this condition, bleeding can be prevented and controlled by administering clotting factor VIII (FVIII). Since their initial availability, recombinant FVIII products have undergone several iterations to enhance their safety. Moroctocog alfa albumin-free cell culture (AF-CC) is among the third generation of recombinant FVIII products and received regulatory approval in China in August 2012. The present study characterizes the single-dose pharmacokinetic parameters of FVIII activity (FVIII:C) after administration of moroctocog alfa (AF-CC) in male Chinese patients with hemophilia A. This multicenter, open-label, single-dose study enrolled 13 male Chinese patients diagnosed with severe hemophilia A (FVIII:C hemophilia A. The pharmacokinetic profile in older patients was similar to that previously reported with recombinant FVIII products in studies with a predominantly white population; younger patients had reduced exposure to FVIII:C. The single doses of moroctocog alfa (AF-CC) were well tolerated; 2 cases of transient, low-titer FVIII inhibitor development were observed. ClinicalTrials.gov identifier: NCT02461992.

    Full Text Available Penelitian mengenai penggunaan asam sitrat sebagai agen pengikat alami masih relatif sedikit. Oleh karena itu penelitian ini difokuskan pada pengaruh jumlah asam sitrat dan suhu pengempaan terhadap sifat papan partikel bambu, termasuk ketahanannya terhadap serangan rayap kayu kering. Bahan penelitian adalah partikel bambu petung. Komposisi kimia bahan baku bambu diuji untuk kadar ekstraktif, holoselulosa, lignin, dan alfa selulosa. Faktor pada penelitian ini adalah jumlah asam sitrat (0 - 40% berdasarkan berat kering udara partikel dan suhu pengempaan (200 oC dan 220 oC. Sifat fisika dan mekanika papan partikel diuji berdasarkan standar pengujian JIS A 5908. Analisis menggunakan Fourier transform infrared spectroscopy (FTIR juga dilakukan untuk mengetahui perubahan gugus ester pada berbagai jumlah asam sitrat dan suhu pengempaan. Pengujian ketahanan terhadap serangan rayap kayu kering juga dilakukan dengan menghitung nilai pengurangan berat dan mortalitas rayap setelah 6 minggu. Hasil pengujian menunjukkan bahwa interaksi kedua faktor berpengaruh nyata terhadap nilai pengembangan tebal, penyerapan air, modulus elastisitas dan modulus patah. Intensitas gugus C=O yang ditunjukkan pada puncak 1720 cm-1 semakin bertambah besar seiiring dengan semakin banyaknya jumlah asam sitrat, yang menyebabkan kekuatan perekatan dan stabilitas dimensi papan partikel menjadi semakin kuat. Kondisi optimum pada penelitian ini adalah papan partikel dengan penambahan jumlah asam sitrat 20 % pada suhu pengempaan 200 oC dengan kualitas yang dapat memenuhi standar JIS A 5908 tipe 8. Penambahan asam sitrat dapat meningkatkan mortalitas rayap kayu kering secara nyata. Penambahan 20 % asam sitrat pada suhu pengempaan 200 oC menghasilkan nilai pengurangan berat 0,9 % dan mortalitas rayap 57 %.

    Full Text Available CORELATION BETWEEN ISLAM AND ECONOMY. This paper aims to identifies about the correlation between economic and Islam. Islam is the perfect religion that governs all things in life, including the economy. This is evident with the concept of  well-being which is described in the al-Quran and Sunnah. Basically the goal of every human life is to prosper, although humans make sense of  well- being with a different perspective. Most understand economics assume that welfare is the welfare of  earthly material. But to make sense of well-being with the term al-Falah, is meaning holistic wellbeing and balance between material and spiritual dimensions. al-Quran and Sunnah have taught that the human being will be achieved if  living in balance between material and spiritual. This is because human life does not just stop in the life of this world, but there is still a second life that will be faced by humanity in the hereafter, and well-being will be achieved with the truth is that people can balance the needs of the world and the hereafter, and that is what is taught in Islamic economics. Keywords: Islam, Economy, Prosperity. Tulisan ini bertujuan untuk menjelasakn tentang korelasi antara ekonomi  dan  Islam.  Islam  adalah  agama  yang  sempurna  yang mengatur segala hal dalam kehidupan ini, termasuk juga ekonomi. Hal ini terbukti dengan konsep kesejahteraan yang dipaparkan dalam al-Quran dan Sunnah. Pada dasarnya tujuan hidup setiap manusia adalah untuk mencapai kesejahteraan, meskipun manusia memaknai kesejahteraan dengan perspektif  yang berbeda-beda. Sebagian besar paham ekonomi menganggap bahwa kesejahteraan adalah kesejahteraan material duniawi. Namun Islam memaknai kesejahteraan dengan istilah  Falah  yang  berarti  kesejahteraan  holistik  dan  seimbang antara dimensi material dan spiritual. Al-Quran dan Sunnah telah mengajarkan bahwa kesejahteraan akan tercapai jika manusia menjalani hidup secara seimbang antara material dan

Media in democracy is a public sphere to communi-cation and makes relation, and a same time as public arena to gain information. But, media also could not release from streotypes and tendency that usually bring of interest, either the owner or ideology. It is meaning media can not released from perspective distorsion, values bias and take a side. Media also effective to become propaganda instrument for a political interest and an ideology. It is seen like how media in US, for example, stereotype of Islam in discourses contradiction and glob-al interest opposition. Then, Islam dominantly identified as doctrine teaches radicalism, fundamen-talism and terorism. Thus, it is often be justification for US to operate the military mission in the name of democracy. Tak dipungkiri pers atau media menjadi salah satu pilar bagi demokrasi. Media dalam demokrasi adalah sebagai ruang bagi publik berkomunikasi dan berinteraksi, sekaligus sarana publik mem-peroleh informasi tentang banyak hal. Namun, media juga tak bisa dilepaskan dari stereotip dan kecenderungan-kecenderungan, yang biasanya membawa kepentingan, baik pemilik maupun ide-ologi. Media karenanya tak lepas dari distorsi perspektif, bias nilai dan berpihak. Media juga efektif menjadi alat propaganda bagi sebuah kepentingan politik dan ideologi, seperti bagaimana media di negara Amerika, misalnya, menstereotipkan Islam dalam analisis pertentangan wacana dan kepent-ingan global. Sehingga, dominan Islam diidentikkan dengan sematan sebagai ajaran yang mengajarkan radikalisme, fundamentalisme dan terorisme.

    Full Text Available Menjadi seorang musisi tidak sekedar bermain musik atau menyanyi saja. Ada jenjang-jenjang yang akan dilewatidalam dunia musik, yang pada akhirnya setiap musisi dihadapkan kepada tanggung jawab dalam dunia tersebut. Di jaman ini, jika jenjang seorang musisi sudah tahap profesional, maka musik dan bisnis merupakan hal yang tidak terpisahkan. Jadi tidak heran jika ada banyak orang yang memimpikan untuk berkarier dalam bidang musik, bahkan telah men1adicita-cita sejak kecil.Jadi penting bagi musisi gerejawi benar-benar "mengkotakkan dirinya" terhadap persepsi yang dianut oleh musisi sekuler, bukan mencampurkannya. Hal ini sangat esensial, karena musisi gerejawi bukan melayani manusia melainkan oleh anugerah Tuhan dipercayakan pekerjaan ini. Dengan demikian pelayanan sebagai musisi gerejawi tidak tercemar oleh persepsi dari dunia musik sekuler. Selain itu musisi gerejawi dapat merefleksikan Tuhan yang disembahnya kepada dunia sekuler, karena tujuan dari semua yang dilakukannya adalah untuk kemuliaan nama Tuhan.

    Stark, Simon Holm; Hansen, Jørgen Beck

    The elastic $pp$ scattering data analyzed in this thesis was taken at the LHC with the ALFA detector at $\\sqrt{s}=8\\text{ TeV}$ with a $\\beta^*=1\\text{ km}$ collision optics which gave access to the Coulomb-Nuclear-Interference region. An improved procedure was used to fit the observed number of elastic events as a function of the four-momentum transfer with a simulation based on theoretical expectations including experimental effects. The data can not exclude any of the investigated parametrizations for the modulus of the nuclear amplitude. The fit results for the total $pp$ cross section, $\\sigma_\\text{tot}$, and the ratio of the real to imaginary forward elastic scattering amplitude, $\\rho$, are: \\begin{align*} \\sigma_\\text{tot} &= 99.1\\pm 0.3 \\text{ (stat.)}\\pm1.6\\text{ (syst.)} \\text{ mb}\\;,\\\\ \\rho &= 0.166\\pm0.017\\text{ (stat.)}\\pm0.019\\text{ (syst.)}\\;, \\end{align*} which are in agreement with previous measurements.

    Matrix metalloproteinases (MMPs) are important enzymes in tissue turnover and various inflammatory processes. In this study, it was evaluated whether serum MMP-8 can predict the response to adjuvant interferon alfa-2b (IFN-α) therapy in patients with operated high-risk cutaneous melanoma. Pre......-treatment sera from 460 patients with stage IIB-IIIC melanoma were analyzed for MMP-8. The patients were randomized after surgery to adjuvant IFN-α for 12 or 24 months (n = 313) or observation only (n = 147). The median serum MMP-8 level was used to classify the patients into a low MMP-8 (n = 232) and a high MMP......-8 (n = 228) group. In the high MMP-8 subgroup, IFN-α therapy significantly improved relapse-free survival (RFS). RFS was 36.8 months in patients with high MMP-8 levels receiving IFN-α therapy, whereas RFS for those with high MMP-8 levels with observation only was 10.6 months (P = 0.027). Median...

    Behçet's disease (BD) involves multisystem vasculitis of unknown origin. Ocular manifestations of BD mostly include bilateral panuveitis and retinal vasculitis, which are very challenging to treat. Interferon alfa-2a (IFN) has been recently introduced for treating refractory Behçet uveitis, mainly in Germany and Turkey. Nonetheless, there is so far no consensus about the ideal treatment regimen of IFN for Behçet uveitis. We report our experience of IFN treatment in five Korean BD patients with refractory uveitis. All patients complained of oral ulcers; one patient had a positive pathergy test and 2 showed the presence of HLA-B51. Immunosuppressive agents used prior to IFN treatment included cyclosporine and methotrexate. The IFN treatment was commenced with a dose of 6-9 MIU/day for 7 days, adjusted according to individual ocular manifestations, tapered down to 3 MIU three times in a week, and then discontinued. All patients showed positive response to IFN treatment; 50% of them showed complete response without additional major ocular inflammation during the follow-up period. Other BD symptoms also improved after IFN treatment in most cases. After treatment, the relapse rate and the required dose of oral corticosteroid were decreased in most cases, showing a significant steroid-sparing effect. However, the visual acuity was not improved in most cases due to irreversible macular sequelae. Despite the small sample size of this study, we suggest that, in Korean patients, IFN is an effective treatment modality for BD uveitis as was observed in German and Turkish patients.

    Full Text Available El Parque Nacional Los Cardones ubicado en la provincia de Salta protege las ecorregiones de Puna, Monte y Pastizal Altoandino Nublado de la Yungas. Nuestro objetivo es evaluar la diversidad alfa y beta de artrópodos en las ecorregiones del Parque. Se muestrearon tres sitios en cada ecorregión utilizando Pit-fall y G-Vac. Se calcularon estimadores no paramétricos de riqueza de especies, la diversidad entre ecorregiones se comparó a través de los “perfiles de diversidad” y “números efectivos de especies”, se analizó el recambio de especies y la complementariedad entre las ecorregiones y sitios de una misma ecorregión. Se registraron 469 spp/morfoespecies, la diversidad en el Parque fue alta, siendo mayor en los Pastizal Altoandino Nublado, y la más baja en la Puna. El inventario llegó al 81% de completitud. El recambio de especies entre ecorregiones fue alto, de esa manera los diferentes ambientes del Parque contribuyen a conservar la diversidad regional de artrópodos. Las ensambles de artrópodos en sitios de una misma ecorregión mostraron mayor similitud entre sí que con sitios más distantes. Se pudo reconocer tres grupos de artrópodos (arañas, dípteros e himenópteros que son diversos y abundantes, los que podrían ser utilizados en futuros estudios como grupos focales.

    Mice experiments have established an important role for interferon regulatory factor (IRF) family members in hematopoiesis. We wanted to study the expression of interferon regulatory factor 4 (IRF4) in various hematologic disorders, especially chronic myeloid leukemia (CML), and its association with response to interferon alfa (IFN-alpha) treatment in CML. Blood samples from various hematopoietic cell lines, different leukemia patients (70 CML, 29 acute myeloid leukemia [AML], 10 chronic myelomonocytic leukemia [CMMoL], 10 acute lymphoblastic leukemia, and 10 chronic lymphoid leukemia patients), and 33 healthy volunteers were monitored for IRF4 expression by reverse transcriptase polymerase chain reaction. Then, with a focus on CML, the IRF4 level was determined in sorted cell subpopulations from CML patients and healthy volunteers and in in vitro-stimulated CML cells. Furthermore, IRF4 expression was compared in the CML samples taken before IFN-alpha therapy and in 47 additional CML samples taken during IFN-alpha therapy. IRF4 expression was then correlated with cytogenetic response to IFN-alpha. IRF4 expression was significantly impaired in CML, AML, and CMMoL samples. The downregulation of IRF4 in CML samples was predominantly found in T cells. In CML patients during IFN-alpha therapy, a significant increase in IRF4 levels was detected, and this was also observed in sorted T cells from CML patients. The increase seen during IFN-alpha therapy was not due to different blood counts. In regard to the cytogenetic response with IFN-alpha, a good response was associated with high IRF4 expression. IRF4 expression is downregulated in T cells of CML patients, and its increase is associated with a good response to IFN-alpha therapy. These data suggest IRF4 expression as a useful marker to monitor, if not predict, response to IFN-alpha in CML.

    Recent immigrant high school students were successfully engaged in learning about Sun-Earth connections through a partnership with the NASA SDO Extreme-Ultraviolet Variability Experiment (EVE) project. The students were enrolled in a pilot course as part of the Math, Engineering and Science Achievement MESA) program. For many of the students, this was the only science option available to them due to language limitations. The English Language Learner (ELL) students doubled their achievement on a pre- and post-assessment on the content of the course. Students learned scientific content and vocabulary in English with support in Spanish, attended field trips, hosted scientist speakers, built and deployed space weather monitors as part of the Stanford SOLAR project, and gave final presentations in English, showcasing their new computer skills. Teachers who taught the students in other courses noted gains in the students' willingness to use English in class and noted gains in math skills. The MESA-EVE course won recognition as a Colorado MESA Program of Excellence and is being offered again in 2007-08. The course has been broken into modules for use in shorter after-school environments, or for use by EVE scientists who are outside of the Boulder area. Other EVE EPO includes professional development for teachers and content workshops for journalists.

    This was a retrospective data analysis to evaluate the treatment response to enzyme replacement therapy (ERT) with Velaglucerase alfa using whole-body magnetic resonance imaging (MRI). A baseline and follow-up MRI were performed on 18 Gaucher Type 1 patients at an interval of 11.6 months. The MRI score systems determined the Bone-Marrow-Burden (BMB) score, the Düsseldorf-Gaucher score (DGS), and the Vertebra-Disc-Ratio (VDR). The Severity Score Index Type 1 (GD-DS3) was also assessed. The baseline MRI medians were: BMB, 7.00; DGS, 3.00; and VDR: 1.70; while, the follow-up MRI medians were: BMB, 7.00; DGS, 3.00; and VDR: 1.73. The baseline GD-DS3 median was 2.40 (BMB excl.: 0.50) and the follow-up median was 2.00 (BMB excl.: 0.50). There was weak statistical significance with the Wilcoxon signed-rank test for the DGS (p=0.034) and GD-DS3 (p=0.047) between both MRIs. Velaglucerase alfa therapy is a effective long-term treatment for Gaucher Type 1 patients who are newly diagnosed or switching therapies. Measurements with whole-body MRI and an objective scoring system were reliable tools for detecting early stage bone marrow activity. Further research is needed to evaluate the "Booster-Effect" of Velaglucerase alfa therapy in Gaucher skeletal disease. Copyright © 2015 Elsevier Inc. All rights reserved.

    In the frame of the program of the Institute for Radiation Protection of ENEA, related to the evaluation of dose from radon and thoron progeny, an alpha spectrometer for the continuous air monitoring (CAM type) of radon and thoron has been realized. The constructive characteristics of the device are here presented together with energy and efficiency calibration. The device allows, by means of a screen type diffusion battery and a filter, to determinate the single radioactivity of each radionuclide of the progeny selecting them in relation to their diffusive behaviour (dichotomous particle size selection). The three-count filter method has been employed to measure the concentrations of {sup 218}Po, {sup 214}Pb and {sup 214}Bi in air. Radon and thoron effective doses using a dosimetric, instead of an epidemiologic approach, will be then evaluated. [Italian] Presso l'Istituto per la Radioprotezione, nell'ambito del programma di valutazione di dose da radon e' stato progettato e realizzato uno spettrometro alfa per il monitoraggio continuo in aria (CAM) della progenie del radon e del toron. Le caratteristiche costruttive dello strumento permettono, tramite l'utilizzo di batterie a diffusione a reti, di determinare l'attivita' individuale della progenie per diverse dimensioni granulometriche in particolare per la frazione attaccata e non al particolato amosferico con un taglio granulometrico di qualche nanometro. E' stato inoltre applicato un metodo spettrometrico a tre conteggi per il calcolo delle concentrazioni individuali della progenie del radon, {sup 218}Po, {sup 214}Pb and {sup 214}Bi, effettuando un conteggio alfa di {sup 218}Po e due conteggi alfa di {sup 214}Po. Tale informazione consentira' una valutazione della dose di radon utilizzando il modello dosimetrico in alternativa a quello epidemiologico.

    Sight-threatening eye involvement is a serious complication of Behçet's disease. Extraocular complications such as arthritis, vascular occlusive disorders, mucocutaneous lesions, and central-nervous-system disease may lead to morbidity and even death. We designed a prospective study in newly diagnosed patients without previous eye disease to assess whether prevention of eye involvement and extraocular manifestations, and preservation of visual acuity are possible with combination treatments with and without interferon alfa-2b. Patients were randomly assigned 3 million units interferon alfa-2b subcutaneously every other day for the first 6 months plus 1.5 mg colchicine orally daily and 1.2 million units benzathine penicillin intramuscularly every 3 weeks (n=67), or colchicine and benzathine penicillin alone (n=68). The primary endpoint was visual-acuity loss. Analysis was by intention to treat. Significantly fewer patients who were treated with interferon had eye involvement than did patients who did not receive interferon (eight vs 27, relative risk 0.21 [95% CI 0.09-0.50], p<0.001). Ocular attack rate was 0.2 (SD 0.62) per year with interferon therapy and 1.02 (1.13) without interferon therapy (p=0.0001). Visual-acuity loss was significantly lower among patients treated with interferon than in those without interferon (two vs 13, relative risk 0.13 [95% CI 0.03-0.60], p=0.003). Arthritis episodes, vascular events, and mucocutaneous lesions were also less frequent in patients treated with interferon than in those not receiving interferon. No serious side-effects were reported. Therapy with interferon alfa-2b, colchicine, and benzathine penicillin seems to be an effective regimen in Behçet's disease for the prevention of recurrent eye attacks and extraocular complications, and for the protection of vision.

    Full Text Available Rapid change of environment is an external force that causes the organization to transform. Fundamentally, the main purpose of the transformation is to change the organizational structure to be more flexible and competitive with fewer hierarchial levels, managers, and employees. The transformation needs to be radical, causing resistance from the organization's members. Their resistance can cause the transformation to fail, therefore organization must find ways to lessen this resistance. First, organization must learn about the diversity of its members' cultures and values. Second, organization must build its own organizational culture which can support the success of the transformation, by communicating it with the members of the organization. To support organizational culture building efforts, it needs changes in human resources practices, especially recruitment and selection. Abstract in Bahasa Indonesia : Perubahan yang cepat dalam lingkungan merupakan kekuatan eksternal yang mengakibatkan transformasi dalam sebuah organisasi. Pada dasarnya, tujuan utama dari transformasi tersebut adalah merubah struktur organisasi agar menjadi lebih fleksibel dan mampu bersaing, dengan tingkat structural yang sedikit, serta jumlah manajer dan karyawan yang lebih kecil. Transformasi tersebut harus menyeluruh, dan hal ini dapat menyebabkan resistensi dari para anggota organisasi yang memperhambat perubahan tersebut. Resistensi itu bisa menyebabkan perubahan tersebut batal, oleh karena itu organisasi harus mencari jalan untuk mengurangi hambatan-hambatan tersebut. Pertama, organisasi harus belajar keanekaragaman dari budaya dan nilai anggotanya. Kedua, organisasi harus mengembangkan budaya organisasi sendiri melalui komunikasi yang baik dengan anggotanya. Untuk mendukung usaha mengembangkan budaya organisasi, harus ada perubaban pada kebijakan sumber daya manusia, terutama dalam rekrutmen dan seleksi karyawan.

    2002-01-01

    Full Text Available Perlawanan kaum petani sudah lama terjadi dalam konteks sejarah hubungan antara si kaya dan si miskin dan antara kaum petani dan negara. Persoralannya selalu bahwa negara, aparat keamanan dan pemilik modal telah mengambil alih secara paksa surplus ekonomi dari petani. Mereka bekerja sama dalam aksi penyerobotan tanah petani, pendirian perkebunan-perkebunan dan dalam menghadapi gerakan protes petani. Negara bukan hanya menghadapi gerakan perlawanan petani dengan represi-represi fisik. Secara sistematis negara juga melakukan propaganda dengan menciptakan gambaran-gambaran yang unfavourable tentang petani pelaku penjarahan dalam berbagai representasi wacana. Dalam batas tertentu, media massa justru memperkuat kecenderungan ini dengan menonjolkan dimensi kekerasan, pemberontakan dan anarkisme dalam mewacanakan aksi-aksi penjarahan petani.

    Full Text Available Dengue virus merupakan salah satu virus anggota dari famili Flaviviridae yang sejak tahun 1956 telah dikenal dapat menimbulkan demam dengue maupun demam berdarah dengue (DBD. Penyakit yang ditularkan oleh nyamuk Aedes aegypti ini diperkirakan telah menjangkiti pada selatar 50-100 juta manusia dengan 500.000 kasus di antaranya dalam manifestasi yang ganas yang dikenal sebagai dengue haemorrhagic fever dan dengue shock syndrome dan 25.000 di antaranya berakibat fatal (meninggal. Saat ini pengembangan vaksin merupakan salah satu solusi yang diharapkan dapat menekan penyebaran penyakit tersebut. E (envelope merupakan salah satu bagian dari protein struktural virus yang sangat penting dalam pengembangan vaksin, yaitu sebagai badan yang memproduksi antibodi netralisasi untuk protein. Non-struktural protein l juga telah diketahui sebagai salah satu komponen penting dalam pengembangan vaksin oleh karena kemampuannya untuk dapat diekspresi pada permukaan sel yang diinfeksi yang dapat menjadi target untuk immune cytolisis. Ada dua pendekatan yang digunakan dalam memproduksi suatu vaksin dengue, yaitu: a. Vaksin hidup yang telah dilemahkan (live attenuated vaccine: b. Vaksin hasil rekayasa (engineered vaccine. Penelitian terhadap vaksin DENV baik rekombinan maupun non-rekombinan yang didasarkan pada uji virus telah dilakukan secara terus-menerus baik pada monyet dan manusia. Sampai saat ini telah dikembangkan sejumlah kandidat vaksin DENV yang berdasar pada tetravalent virus dengue, yaitu a. vaksin konvensional, b. vaksin dengue rekombinan berdasar pada flavivirus, c. vaksin intertypic chimeric, d. vaksin chimerivac, e. vaksin dengue rekombinan menggunakan vector non-ftavivirus dan f. vector adenovirus. Namun demikian, sampai sekarang belum ada vaksin yang siap digunakan untuk menangkal infeksi ke empat serotype virus dengue, sehingga masih diharapkan untuk pengembangan virus lebih lanjut.   Kata kunci: Aedes aegypti, dengue virus, vaksin dengue.

    Full Text Available El coeficiente alfa de Cronbach es el modo más habitual de estimar la fiabilidad de pruebas basadas en Teoría Clásica de los Test. En dicha estimación, los investigadores usualmente omiten informar intervalos de confianza para el coeficiente, un aspecto no solo recomendado por los especialistas, sino también requerido explícitamente en las normas editoriales de algunas revistas especializadas. Esta situación puede atribuirse a que los métodos de estimación de intervalos de confianza son poco conocidos, además de no estar disponibles al usuario en los programas estadísticos más populares. Así, en este trabajo se presenta un programa desarrollado dentro del sistema estadístico ViSta que permite calcular intervalos de confianza basados en el enfoque clásico y mediante la técnica bootstrap. Se espera promover la inclusión de intervalos de confianza para medidas de fiabilidad, facilitando el acceso a las herramientas necesarias para su aplicación. El programa es gratuito y puede obtenerse enviando un mail de solicitud al autor del trabajo.Cronbach's alpha coefficient is the most popular way of estimating reliability in measurement scales based on Classic Test Theory. When estimating it, researchers usually omit to report confidence intervals of this coefficient, as it is not only recommended by experts, but also required by some journal's guidelines. This situation is because the different methods of estimating confidence intervals are not well-known by researchers, as well as they are not being available among the most popular statistical packages. Therefore, this paper describes a computer program integrated into the ViSta statistical system, which allows computing confidence intervals based on the classical approach and using bootstrap technique. It is hoped that this work promotes the inclusion of confidence intervals of reliability measures, by increasing the availability of the required computer tools. The program is free and

    Full Text Available Abstract: Sufism in the eras of globalization and information often faces considerable challenges. The function and role of religion in modern life have in some aspects diminished, including sufism because it is claimed to have played no or less role in resolving problems nor stimulating social change. As one of Islamic traditions, sufism makes ihsan as its essential teaching. By this concept, sufism encourages humans to pray to God wholeheartedly. Sufism is now required to show its own existence and function by making fundamental contribution for modern life, an era which differ socio-culturally from the one when sufism firstly emerged. Sufism thus needs to adapt itself to the changes in the era of information and globalization so that it will remain relevant and suitable for human progress. Sufism needs to release itself from its exclusivism and to avoid being trapped in its own logic, namely speculative-trancendentalism Abstrak: Tasawuf di era globalisasi dan informasi seperti saat ini tengah menghadapi tantangan yang sangat berat. Kehidupan modern sudah sampai pada taraf tidak lagi mempercayai fungsi dan peran agama, termasuk di dalamnya tasawuf, sebagai ‘sesuatu’ yang dapat memberikan solusi bagi perubahan sosial. Sebagai manifestasi paripurna dari ajaran Islam, tasawuf berintikan pada konsep Ihsān yang mengajarkan untuk beribadah kepada Sang Pencipta secara ikhlas. Untuk menunjukkan eksistensinya, tasawuf dituntut peran aktifnya secara konstruktif-solutif terhadap berbagai kebutuhan manusia modern yang amat berbeda dengan setting maupun struktur masyarakat pada saat tasawuf “dilahirkan” pada zamannya. Tasawuf dituntut untuk memerlukan “baju” baru di era informasi yang kerap berubah ini, agar tetap realible dan suitable dengan kemajuan zaman. Hal itu dapat dilakukan dengan berusaha “keluar” dari eksklusifismenya dengan meminjam tradisi filsafat analitik pasca positivisme dan tradisi eksistensialis serta dinamika filsafat

    Full Text Available O colesteatoma adquirido da orelha média causa erosão óssea, com altas taxas de morbidade e mortalidade. O TNF-alfa (TNF-alfa lambda uma das principais citocinas envolvidas neste processo. OBJETIVO: Avaliar o papel do TNF-alfa na reabsorsão óssea e a ação dele no colesteatoma. MATERIAL E MÉTODOS: Foi realizado um levantamento e uma revisão crítica da literatura. RESULTADOS: Todos os autores estudados concordam com a importância do TNF-alfa no processo de reabsorção óssea presente no colesteatoma e com o grau de destruição observado. Diferentes trabalhos demonstraram que o TNF-alfa é capaz de provocar erosão óssea, através de diferentes vias de ação. Ele pode estimular a diferenciação e a maturação dos osteoclastos ou, ainda, agir na matriz óssea expondo-a à ação dos osteoclastos. Existe a possibilidade de inibir a ação do TNF-alfa, diminuindo seus efeitos e prevenindo a perda óssea em doenças como a artrite reumatóide. Não existe, entretanto, trabalhos específicos em colesteatoma. Não existe consenso sobre a sua localização. Estas diferenças, provavelmente, ocorrem devido à distribuição dos receptores. CONCLUSÃO: O TNF-alfa, presente no colesteatoma promove a reabsorsão óssea, juntamente com outras citocinas (RANKL e IL-1, estando relacionado com a presença de complicações.Cholesteatoma may cause bone erosion, with high morbidity and mortality rates. Tumor Necrosis Factor -Alpha (TNF-a is one of the main cytokines involved in this process. Our goal was to evaluate the role of TNF-a in Bone Resorption and its effect on cholesteatoma.

    This work aims at realizing an optimal hydrolysis of pretreated Alfa fibers (Stipa tenacissima) through the use of enzymes produced from Talaromyces thermophilus AX4, namely β-d-glucosidase and xylanase, by a solid state fermentation process of an agro-industrial waste (wheat bran supplemented with lactose). The carbon source was firstly selected and the optimal values of three other parameters were determined: substrate loading (10g), moisture content (85%) and production time (10days); which led to an optimized enzymatic juice. The outcome was then supplemented with cellulases of T. reesei and used to optimize the enzymatic saccharification of alkali-pretreated Alfa fibers (PAF). The maximum saccharification yield of 83.23% was achieved under optimized conditions (substrate concentration 3.7% (w/v), time 144h and enzyme loading of 0.8 FPU, 15U CMCase, 60U β-d-glucosidase and 125U xylanase).The structural modification of PAF due to enzymatic saccharification was supported by the changes of morphologic and chemical composition observed through macroscopic representation, FTIR and X-Ray analysis.

    The ATLAS experiment with the ALFA sub-detector, provides a unique opportunity to measure elastic proton--proton scattering at the LHC at a centre-of-mass energy of $\\sqrt{s} = 7$ TeV, that has never been reached before. The ALFA detector is a tracking detector housed in Roman Pots, which makes it possible to measure elastically scattered protons down to very small scattering angles. From the proton tracks, measured during a LHC fill with special $\\beta^{*} = 90$ m beam optics, the differential elastic cross-section as a function of the four-momentum transfer squared $t$ is determined, and the total hadronic cross-section $\\sigma_\\text{tot}$, the nuclear slope parameter $B$ and further derived quantities are extracted by utilizing the optical theorem. The total hadronic cross-section is a fundamental parameter of strong interaction depending on the centre-of-mass energy. It has been measured for more than 50 years at different energies and accelerators, where a rise with energy was observed. A newly developed...

    The objective of this observational study was the early evaluation of the impact, a week after the first administration of epoetin alfa 40000 U once weekly and i.v. dose of 62.5 mg sodium ferric gluconate for seven days in improving hemoglobin levels in cancer patients affected by mild/moderate or severe anemia during chemotherapy. Twenty patients affected by solid tumors who received epoetin alfa 40000 U once weekly and daily i.v. sodium ferric gluconate for one week were evaluated: 90% of the patients showed hemoglobin increase, with a median level of hemoglobin increase of 0.73 g/L from baseline, and 50% of them showing a hemoglobin increase > 1 gr/L. The treatment was well tolerated and no adverse event was observed. The early increase of hemoglobin level from baseline is interesting and suggestive for the possibility of achieving an adequate hemoglobin level with a short-term treatment. It is still necessary to further explore the real need of iron supplementation to maintain adequate erythropoiesis prior and during epoetin therapy

Dengan kompetensi-kompetensi tersebut diharapkan siswa dapat memiliki kemampuan menerima, mengelola, dan memanfaatkan pengetahuan yang diperolehnya untuk bertahan hidup dalam keadaan yang selalu berubah dan kompetitif. Latihan berpikir, merumuskan dan memecahkan masalah serta mengambil kesimpulan akan membantu siswa untuk mengembangkan pemikirannya atau intelegensinya. Dengan demikian, semakin banyak siswa berlatih memecahkan masalah matematis maka akan semakin mengerti dan berkembang cara berpikirnya. Kemahiran siswa dalam memecahkan masalah matematis, dipengaruhi oleh kemampuannya dalam memahami matematika. Kemampuan bernalar berperan penting dalam memahami matematika. Bernalar secara matematis merupakan suatu kebiasaan berpikir, dan layaknya suatu kebiasaan, maka penalaran semestinya menjadi bagian yang konsisten dalam setiap pengalaman-pengalaman matematis siswa. Dari pengalaman-pengalaman awal siswa belajar materi matematika, penting bagi guru untuk membantu siswa memahami bahwa penegasan-penegasan harus selalu mempunyai alasan. Komunikasi matematis berperan penting pada proses pemecahan masalah. Melalui komunikasi ide bisa menjadi objek yang dihasilkan dari sebuah refleksi, penghalusan, diskusi, dan pengembangan. Proses komunikasi juga membantu dalam proses pembangunan makna dan pempublikasian ide. Ketika para siswa ditantang untuk berpikir dan bernalar tentang matematika dan mengomunikasikan hasil pikiran mereka secara lisan atau dalam bentuk tulisan, sebenarnya mereka sedang belajar menjelaskan dan meyakinkan.

    Near Fault Observatories (NFOs) are innovative research infrastructures based on dense, state of the art networks of multi-parametric sensors that continuously monitor the underlying Earth instability processes over a broad time interval. They aim at understanding the physical/chemical processes responsible for earthquakes and faulting and tracking their evolution over time by enabling advancements in ground shaking prediction. EPOS-IP is aimed at contributing in creating and harmonizing data and products distributors from seven NFOs, operating on different tectonic regimes and different areas of Europe. They include plate boundary systems at South Iceland Seismic Zone, the Marmara Sea and the Corinth rift. In mountain settings, NFOs monitor the Alto Tiberina and Irpinia faults in the Apennine mountain range, the Valais region in the Alps, and the Vrancea fault in the Carpathian Mountains. They monitor diverse faulting mechanisms (strike-slip, normal and thrust), high to low angle faults, shallow and deep faults, as well as regions with fast and slow strain rate accumulation. The focus of the observatories varies, ranging from small- to large-scale seismicity and includes the role of different parameters such as fluid playing in fault initiation, the internal structure of fault systems, site effects and derived processes such as earthquake generated landslides and tsunamis. In response to their specific objectives, the NFOs operate a diverse set of monitoring instrumentation using seismic, deformation, strain, geochemical and electromagnetic equipment. Since NFO methodological approach is based on extremely dense networks and less common instruments deserving multi-parameter data description, a main goal of this group is to build inclusive and harmonised services supporting the installation over the next decade of tens of near-fault observatories monitoring active faults in different tectonic environments in Europe. The NFO Thematic Core Service (TCS) relies on

    Taliglucerase alfa is a β-glucosidase enzyme replacement therapy (ERT) approved in the US and other countries for the treatment of Gaucher disease (GD) in adults and is approved in pediatric and adult patients in Australia and Canada. It is the first approved plant cell-expressed recombinant human protein. A Phase 3, multicenter, open-label, 9-month study assessed safety and efficacy of switching to taliglucerase alfa in adult and pediatric patients with GD treated with imiglucerase for at least the previous 2years. Patients with stable disease were offered taliglucerase alfa treatment using the same dose (9-60U/kg body weight) and regimen of administration (every 2weeks) as imiglucerase. This report summarizes results from 26 adult and 5 pediatric patients who participated in the trial. Disease parameters (spleen and liver volumes, hemoglobin concentration, platelet count, and biomarker levels) remained stable through 9months of treatment in adults and children following the switch from imiglucerase. All treatment-related adverse events were mild or moderate in severity and transient in nature. Exploratory parameters of linear growth and development showed positive outcomes in pediatric patients. These findings provide evidence of the efficacy and safety profile of taliglucerase alfa as an ERT for GD in patients previously treated with imiglucerase.

    Anecdotal reports suggest that the currently approved dosing interval of agalsidase alfa (0.2 mg/kg/2 weeks) for Fabry disease treatment is too long. This randomised, double-blind, placebo-controlled, crossover study investigated three altered dosing intervals. 18 Fabry patients received three agalsidase alfa dosing schedules, each for four weeks (A: 0.2 mg/kg∗2 weeks, B: 0.1 mg/kg/week, C: 0.2 mg/kg/week). Health state, pain levels, sweat volume and latency and plasma and urinary globotriaosylceramide levels were recorded throughout the study. No significant differences were found among the schedules for the primary efficacy outcome of self-assessed health state, or for pain scores. A trend toward increased sweat volume on QSART testing, and reduced urine globotriaosylceramide concentration were seen with treatment schedule C. Agalsidase alfa was safe and well tolerated with all schedules. In conclusion, the primary analyses did not find weekly infusions of agalsidase alfa to be statistically better than the approved dosing schedule however the data indicates that further studies with more patients over a longer period are required to more accurately determine the optimum dose and schedule.

    EPIC-3 is a prospective, international study that has demonstrated the efficacy of PEG-IFN alfa-2b plus weight-based ribavirin in patients with chronic hepatitis C and significant fibrosis who previously failed any interferon-alfa/ribavirin therapy. The aim of the present study was to assess FibroTest (FT), a validated non-invasive marker of fibrosis in treatment-naive patients, as a possible alternative to biopsy as the baseline predictor of subsequent early virologic (EVR) and sustained virologic response (SVR) in previously treated patients. Of 2312 patients enrolled, 1459 had an available baseline FT, biopsy, and complete data. Uni- (UV) and multi-variable (MV) analyses were performed using FT and biopsy. Baseline characteristics were similar as in the overall population; METAVIR stage: 28% F2, 29% F3, and 43% F4, previous relapsers 29%, previous PEG-IFN regimen 41%, high baseline viral load (BVL) 64%. 506 patients (35%) had undetectable HCV-RNA at TW12 (TW12neg), with 58% achieving SVR. The accuracy of FT was similar to that in naive patients: AUROC curve for the diagnosis of F4 vs F2=0.80 (p<0.00001). Five baseline factors were associated (p<0.001) with SVR in UV and MV analyses (odds ratio: UV/MV): fibrosis stage estimated using FT (4.5/5.9) or biopsy (1.5/1.6), genotype 2/3 (4.5/5.1), BVL (1.5/1.3), prior relapse (1.6/1.6), previous treatment with non-PEG-IFN (2.6/2.0). These same factors were associated (p ≤ 0.001) with EVR. Among patients TW12neg, two independent factors remained highly predictive of SVR by MV analysis (p ≤ 0.001): genotype 2/3 (odds ratio=2.9), fibrosis estimated with FT (4.3) or by biopsy (1.5). FibroTest at baseline is a possible non-invasive alternative to biopsy for the prediction of EVR at 12 weeks and SVR, in patients with previous failures and advanced fibrosis, retreated with PEG-IFN alfa-2b and ribavirin.

    This prospective, multicenter, community-based and academic-based, open-label, investigator-initiated, U.S. study evaluated efficacy and safety of pegylated interferon (PEG-IFN) alfa-2b plus a flat or weight-based dose of ribavirin (RBV) in adults with chronic hepatitis C. Patients (n = 5027) were randomly assigned to receive PEG-IFN alfa-2b 1.5 microg/kg/week plus flat-dose (800 mg/day) or weight-based (800-1400 mg/day) RBV for 48 weeks (patients with genotype 1, 4, 5, or 6) and for 24 or 48 weeks (genotype 2/3 patients). Primary end point was sustained virologic response (undetectable [<125 IU/mL] serum hepatitis C virus RNA at 24-week follow-up). Sustained virologic response, but not end-of-treatment, rates were significantly higher with weight-based than with flat-dose RBV (44.2% versus 40.5%; P = 0.008). Sustained virologic response rates by intention-to-treat analysis were 34.0% and 28.9%, respectively, in genotype 1 patients (P = 0.005) and 31.2% and 26.7%, respectively, in genotype 1 patients with high baseline viral load (P = 0.056). In genotype 2/3 patients, rates were not significantly different (61.8% and 59.5%, respectively) regardless of treatment duration. Besides greater hemoglobin reductions with weight-based RBV, safety profiles were similar across RBV dosing groups, including the 1400-mg/day group. PEG-IFN alfa-2b plus weight-based RBV is more effective than flat-dose RBV, particularly in genotype 1 patients, providing equivalent efficacy across all weight groups. RBV 1400 mg/day is appropriate for patients 105 to 125 kg. For genotype 2/3 patients, 24 weeks of treatment with flat-dose RBV is adequate; no evidence of additional benefit of extending treatment to 48 weeks was demonstrated.

METHODS: The data on 152 eligible patients, from 16 CF reference centers, that answered the medical questionnaires and performed laboratory tests at baseline (T0, and at six (T2 and 12 (T4 months after dornase alfa initiation, were analyzed. Three age groups were assessed: six to 11, 12 to 13, and >14 years. Pulmonary tests, airway microbiology, emergency room visits, hospitalizations, emergency and routine treatments were evaluated. Student's t-test, chi-square test and analysis of variance were used when appropriated. RESULTS: Routine treatments were based on respiratory physical therapy, regular exercises, pancreatic enzymes, vitamins, bronchodilators, corticosteroids, and antibiotics. In the six months prior the study (T0 phase, hospitalizations for pulmonary exacerbations occurred in 38.0, 10.0 and 61.4% in the three age groups, respectively. After one year of intervention, there was a significant reduction in the number of emergency room visits in the six to 11 years group. There were no significant changes in forced expiratory volume in one second (VEF1, in forced vital capacity (FVC, in oxygen saturation (SpO2, and in Tiffenau index for all age groups. A significant improvement in Shwachman-Kulczychi score was observed in the older group. In the last six months of therapy, chronic or intermittent colonization by P. aeruginosa was detected in 75.0, 71.4 and 62.5% of the studied groups, respectively, while S. aureus colonization was identified in 68.6, 66.6 and 41.9% of the cases. CONCLUSIONS: The treatment with dornase alfa promoted the maintenance of pulmonary function parameters and was associated with a significant reduction of emergency room visits due to pulmonary exacerbations in the six to 11 years age group, with better clinical scores in the >14 age group, one

    Full Text Available Abstrak Latar Belakang: Epistaksis merupakan suatu kondisi klinis yang sering ditemui dan dapat terjadi pada semua umur dengan banyak variasi penyebabnya. Salah satu faktor risiko yang diduga ikut berperan dalam terjadinya epistaksis adalah hipertensi. Tujuan: Menjelaskan hubungan antara epistaksis dengan hipertensi. Tinjauan Pustaka: Hipertensi diduga tidak menyebabkan epistaksis secara langsung, tapi memperberat episode epistaksis. Mengendalikan tekanan darah sebagai salah satu faktor risiko, akan menurunkan insiden terjadinya epistaksis. Di ruang gawat darurat, pemberian obat anti hipertensi diberikan sebelum atau bersamaan dengan manajemen epistaksis itu sendiri. Kesimpulan: Terdapat hubungan antara epistaksis dengan hipertensi yang berlangsung lama dan adanya hipertrofi ventrikel kiri. Kata kunci : Hipertensi, kegawatdaruratan, penatalaksanaan epistaksis. Abstract Background: Epistaxis is a common clinical problem in all age groups with varied etiological factors. Hypertension has been suggested as a risk factor in epistaxis case. Purpose: To explain relationship between epistaxis and hypertension. Review: It has been suggested that hypertension does not cause epistaxis directly, but hypertension prolongs the episode of epistaxis when it does occur. The controlling for blood pressure as a risk factor will be decreased the incidencies of epistaxis. In emergency rooms, high blood pressure is usually treated before or in parallel with the management of epistaxis. Conclusion: There was an association between epistaxis and long duration of hypertension in adult and left ventricle hypertrophy. Key words : Hypertension, emergency case, management of epistaxis.
