    Due to its extraordinarily high concentration of known relativistic particle accelerators such as pulsar wind nebula, supernova remnants, dense molecular cloud regions, and the supermassive black hole (Sgr A*); the center of the Milky Way galaxy has long been an ideal target for high energy (HE, 0.1-100 GeV) and very high energy ( VHE, 50 GeV-50 TeV) gamma-ray emission. Indeed, detections of Sgr A* and other nearby regions of gamma-ray emission have been reported by EGRET and Fermi-LAT in the HE band, as well as CANGAROO, Whipple, HESS, VERITAS, and MAGIC in the VHE band. Here we report on the results of extended observations of the region with VERITAS between 2010-2014. Due to the visibility of the source for VERITAS in the Northern Hemisphere, these observations provide the most sensitive probe of gamma-ray emission above 2 TeV in one of the most complicated and interesting regions of our home galaxy.

    Photosynthesis powers life on our planet. The basic photosynthetic architecture comprises antenna complexes to harvest solar energy and reaction centers to convert the energy into a stable charge separated state. In oxygenic photosynthesis, the initial charge separation event occurs in the photosystem II reaction center; the only known natural enzyme that uses solar energy to split water. Energy transfer and charge separation in photosynthesis are rapid and have high quantum efficiencies. Recently, nonlinear spectroscopic experiments have suggested that electronic coherence may play a role in energy transfer efficiency in antenna complexes. Here we report the observation of coherence in the photosystem II reaction center by two dimensional electronic spectroscopy. The frequencies of the observed coherences match exciton difference frequencies and/or known vibrational modes of the photosystem II reaction center. These observations raise questions about the possible role of electronic and/or vibrational coheren...

  4. The Universe Observation Center: an educational center devoted to Astronomy in Catalonia

    Fernández, D.

    The Universe Observation Center (in Catalan language, Centre d'Observació de l'Univers, COU) is located in close proximity to the Montsec Astronomical Observatory (Observatori Astronòmic del Montsec, OAM), in eastern Catalonia (Spain). Both centers comprise the Montsec Astronomical Park (Parc Astronòmic Montsec, PAM), managed by the Consorci del Montsec. Montsec Mountain remains the finest location for astronomical observation in Catalonia, as demonstrated by a site-testing campaign conducted by the Astronomy and Meteorology Department of the University of Barcelona. The COU consists of a Central Building (including a permanent exhibition and three classrooms possessing broadband Internet access), the Telescope Park (two astronomical domes equipped with medium-size telescopes, a coelostat for solar observation, and a portable telescope park), the Eye of Montsec (a digital planetarium and, at the same time, an extremely innovative platform for sky observation) and the Garden of the Universe (a tour of the land surrounding the COU, visiting several areas within it). The COU will offer to the Spanish academic community a host of fascinating and unique activities in the fields of astronomy and geology. The Center is open not only to students (from primary school through university), but also to amateur astronomers, people interested in science and the general public.

    The Integrated Ocean Observing System (IOOS) is the U.S. contribution to the Global Ocean Observing System and the Global Earth Observing System of Systems (GEOSS). As the Integrated Ocean Observing System Data Assembly Center (IOOS DAC), the National Oceanic and Atmospheric Administration`s (NOAA) National Data Buoy Center (NDBC) collects data from ocean observing systems and performs quality control on the data. Once the IOOS DAC performs the quality control, it distributes them in real-time: (1) in World Meteorological Organization alphanumeric data formats via the Global Telecommunications System (GTS) that provides instant availability to national and international users (2) in text files via its website (http://www.ndbc.noaa.gov) that provide easy access and use, and (3) in netCDF format via its OPeNDAP/DODS Server (http://dods.ndbc.noaa.gov) that provides higher resolution data than available in WMO alphanumeric or text file formats. The IOOS DAC routinely checks and distributes data from about 200 NDBC stations that include meteorological and oceanographic observations from buoys and coastal stations, water-level estimations from tsunameters (DART), and climate monitoring from buoys (Tropical Atmosphere Ocean array (TAO)). The IOOS DAC operates continuously - 24 hours per day, 7 days per week. In addition to data from NDBC`s platforms, the IOOS DAC applies its scientific expertise and data management and communications capabilities to facilitate partnerships for the exchange and application of data and to coordinate and leverage regional assets and resources from about 350 IOOS Partner stations. The IOOS DAC through its quality control process provides feedback to its partners on the quality of their observation that can lead to improved quality of the observations. The NDBC-IOOS Data Partnerships span the Western Hemisphere with data collection from the Beaufort Sea to the Peru Current, from the International Date Line to the central Atlantic Ocean, and

  6. The Universe Observing Center a modern center to teach and communicate astronomy

    2011-06-01

    The Universe Observing Center is one of the parts of the Parc Astronòmic Montsec (PAM). PAM is an initiative of the Catalan government, through the Consorci del Montsec (Montsec Consortium), to take advantage of the capabilities and potential of the Montsec region to develop scientific research, training and outreach activities, particularly in the field of Astronomy. The choice of the Montsec mountains to install the PAM was motivated by the magnificent conditions for observing the sky at night; the sky above Montsec is the best (natural sky free of light pollution) in Catalonia for astronomical observations. The PAM has two main parts: the Observatori Astronòmic del Montsec (OAdM) and the Universe Observing Center (COU). The OAdM is a professional observatory with an 80-cm catadioptric telescope (Joan Oró Telescope). This telescope is a robotic telescope that can be controlled from anywhere in the world via the Internet. The COU is a large multipurpose center which is intended to become an educational benchmark for teaching and communicate astronomy and other sciences in Catalonia. The management of the COU has three main goals: 1) Teach primary and secondary school students in our Educational Training Camp. 2) Teach university students housing the practical astronomy lectures of the universities. 3) Communicate astronomy to the general public. The COU comprises special areas for these purposes: the Telescopes Park with more than 20 telescopes, a coelostat for solar observations and two dome containing full-automated telescopes. The most special equipment is ``The Eye of Montsec'', with its 12m dome containing a multimedia digital planetarium and a platform for direct observation of the sky and the environment. During 2009 we expect around 10000 visitors in Montsec area to enjoy science with Montsec dark skies and an special natural environment.

  7. ISO observations of the Galactic center Interstellar Medium: ionized gas

    2004-01-01

    (Abridged) We present fine structure and recombination lines observations of the ionized gas toward a sample of 18 sources located within 300 pc of the center of the Galaxy (GC). The fine structure lines from [NII] and [SIII] have been detected in 16 sources. In 10 sources we have even detected the [OIII] 88 $\\mu$m line. The measured N, S and Ne abundances are similar to those measured in the HII regions in the 5-kpc ring and in the nuclei of starburst galaxies. The fine structure lines ratios measured for all the sources can be explained by photo-ionization with an effective temperature of 32000-37000 K and an ionization parameter, $U$, of $-1>\\log U > -3$. The highest excitation is found in the Radio Arc region but there must be more ionizing sources distributed over the Galactic center than the known clusters of massive stars. Most of the clouds are located far from the prominent continuum complexes (Sgr C, B ...). However, it is possible that the clouds are ionized by escaped photons from those complexes....

    The structure of nanoparticles plays a critical role in dictating their material properties. Gold is well known to adopt face-centered cubic (fcc) structure. Herein we report the first observation of a body-centered cubic (bcc) gold nanocluster composed of 38 gold atoms protected by 20 adamantanethiolate ligands and two sulfido atoms ([Au38S2(SR)20], where R=C10H15) as revealed by single-crystal X-ray crystallography. This bcc structure is in striking contrast with the fcc structure of bulk gold and conventional Au nanoparticles, as well as the bi-icosahedral structure of [Au38(SCH2CH2Ph)24]. The bcc nanocluster has a distinct HOMO-LUMO gap of ca. 1.5 eV, much larger than the gap (0.9 eV) of the bi-icosahedral [Au38(SCH2CH2Ph)24]. The unique structure of the bcc gold nanocluster may be promising in catalytic applications.

    We report on the diffuse X-ray emissions from the Galactic center (GCDX) observed with the X-ray Imaging Spectrometer (XIS) on board the Suzaku satellite. The highly accurate energy calibrations and extremely low background of the XIS provide many new facts on the GCDX. These are (1) the origin of the 6.7/7.0keV lines is collisional excitation in hot plasma, (2) new SNR and super-bubble candidates are found, (3) most of the 6.4keV line is fluorescence by X-rays, and (4) time variability of the 6.4keV line is found from the SgrB2 complex.

    We report the Herschel detections of hydrogen fluoride (HF) and para-water (p-H{sub 2}O) in gas intercepting the sight lines to two well-studied molecular clouds in the vicinity of the Sgr A complex: G-0.02-0.07 (the {sup +}50 km s{sup -1} cloud{sup )} and G-0.13-0.08 (the {sup +}20 km s{sup -1} cloud{sup )}. Toward both sight lines, HF and water absorption components are detected over a wide range of velocities covering {approx}250 km s{sup -1}. For all velocity components with V{sub LSR} > -85 km s{sup -1}, we find that the HF and water abundances are consistent with those measured toward other sight lines probing the Galactic disk gas. The velocity components with V{sub LSR} {<=} -85 km s{sup -1}, which are known to trace gas residing within {approx}200 pc of the Galactic center, however, exhibit water vapor abundances with respect to HF at least a factor three higher than those found in the Galactic disk gas. Comparison with CH data indicates that our observations are consistent with a picture where HF and a fraction of the H{sub 2}O absorption arise in diffuse molecular clouds showing Galactic disk-like abundances while the bulk of the water absorption arises in warmer (T {>=} 400 K) diffuse molecular gas for V{sub LSR} {<=} -85 km s{sup -1}. This diffuse Interstellar Medium (ISM) phase has also been recently revealed through observations of CO, HF, H{sup +}{sub 3}, and H{sub 3}O{sup +} absorption toward other sight lines probing the Galactic center inner region.

  12. Beyond active learning: a case study of teaching practices in an occupation-centered curriculum.

    Hooper, Barbara

    2006-01-01

    Although occupation-centered curricula are highly promoted, the teaching processes that convey such designs remain unclear. This case study elucidated occupation-centered teaching practices. Interview and observational data were collected over 8 weeks, and analysis involved coding transcriptions, data matrices, concept maps, journaling, and writing. Participants augmented active learning strategies with strategies that linked course topics to the subject of occupation. The use of linking strategies suggested that: (a) course content was treated as two-tiered; (b) neither content nor instructional processes were inherently occupation-centered; and (c) subject-centered education strengthens social learning theories. Although curricula may appear occupation-centered based on a curriculum description and course content, ultimately "linking opportunities" in the classroom constitute an essential feature that demarcates a program as occupation-centered.

    2017-01-01

    We present observations of 36 GHz Class I methanol masers taken with the Karl G. Jansky Very Large Array (VLA) in the B configuration with the aim of detecting the Zeeman Effect. We targeted several 36 GHz Class I methanol masers associated with supernova remnants (SNRs) toward the Galactic Center. Each source was observed in dual circular polarizations for three hours. The observed spectral profiles of the masers are complex, with several components blended in velocity. In only one case was the Stokes V maser profile prominent enough to reveal a 2-sigma hint of a magnetic field of zBlos = 14.56 +/- 5.60 Hz; we have chosen to express our results in terms of zBlos since the Zeeman splitting factor (z) for 36 GHz methanol masers has not been measured. There are several hints that these spectra would reveal significant magnetic fields if they could be spatially and spectrally resolved.

    2012-01-01

    Sparse aperture masking (SAM) interferometry combined with Adaptive Optics (AO) is a technique that is uniquely suited to investigate structures near the diffraction limit of large telescopes. The strengths of the technique are a robust calibration of the Point Spread Function (PSF) while maintaining a relatively high dynamic range. We used SAM+AO observations to investigate the circumstellar environment of several bright sources with infrared excess in the central parsec of the Galaxy. For our observations, unstable atmospheric conditions as well as significant residuals after the background subtraction presented serious problems for the standard approach of calibrating SAM data via interspersed observations of reference stars. We circumvented these difficulties by constructing a synthesized calibrator directly from sources within the field-of-view. When observing crowded fields, this novel method can boost the efficiency of SAM observations because it renders interspersed calibrator observations unnecessary...

    2011-08-01

    The recently published report of the Carnegie Foundation's National Study of Nursing Education points out significant problems with classroom teaching in schools of nursing. This article suggests Palmer's idea of the subject-centered classroom as a way to transform nursing school classrooms into collaborative learning communities. For Palmer, the subject is the big idea of nursing practice-the nurse-patient/client/family/community relationship-that should take the lead in stimulating inquiry and discussion. The article goes on to describe how teachers can develop and use unfolding case studies to bring the subject to the center of the classroom. By doing so, the classroom becomes a place where students learn a sense of salience, develop their clinical imagination, and begin their formation as professional nurses.

    Hydatidiform moles (HMs) are abnormal human pregnancies with vesicular chorionic villi, imposing two clinical challenges; miscarriage and a risk of gestational trophoblastic neoplasia (GTN). The parental type of most HMs are either diandric diploid (PP) or diandric triploid (PPM). We consecutively collected 154 triploid or near-triploid samples from conceptuses with vesicular chorionic villi. We used analysis of DNA markers and/or methylation sensitive-MLPA and collected data from registries and patients records. We performed whole genome SNP analysis of one case of twinning (PP+PM).In all 154 triploids or near-triploids we found two different paternal contributions to the genome (P1P2M). The ratios between the sex chromosomal constitutions XXX, XXY, and XYY were 5.7: 6.9: 1.0. No cases of GTN were observed. Our results corroborate that all triploid human conceptuses with vesicular chorionic villi have the parental type P1P2M. The sex chromosomal ratios suggest approximately equal frequencies of meiosis I and meiosis II errors with selection against the XYY conceptuses or a combination of dispermy, non-disjunction in meiosis I and meiosis II and selection against XYY conceptuses. Although single cases of GTN after a triploid HM have been reported, the results of this study combined with data from previous prospective studies estimate the risk of GTN after a triploid mole to 0% (95% CI: 0–1,4%).

    Dofetilide is a class III antiarrhythmic used for treating atrial dysrhythmias. Though its adverse effects are well described in routine use, very little is known about dofetilide toxicity in overdose. This is a retrospective case series of consecutive patients reported to our poison center after dofetilide overdose. Twenty-seven cases were included. Seventeen patients were treated at a healthcare facility, and of these, eight were admitted. Twenty-one patients took one extra capsule, four took someone else's medication, one took three extra capsules, and one had a large intentional overdose. Ten patients had co-ingestants reported, including three QT-prolonging agents. No one required cardioversion, defibrillation, CPR, or overdrive pacing. The patient who reported taking 90 times his usual dose in suicide attempt was the only patient to have significant clinical effects. He experienced an 8-beat run of non-sustained ventricular tachycardia, frequent multifocal PVCs, and ventricular bigeminy. He received magnesium sulfate and potassium chloride supplementation. In this series, unintentional small overdoses did not result in significant clinical effects and were often managed successfully at home, despite the fact that information showing a single capsule can cause torsades. This study is limited by its small sample size, retrospective design, and reliance on incomplete information.

    Jatropha curcas L. is an inedible plant belonging to the Euphorbiaceae family that is growing in subtropical zones of all continents. We report a series of 24 cases of poisoning with J. curcas seeds or fruits reported to poison centers in Paris and Marseille between December 2000 and June 2014. Fifteen adults and 9 children ingested J. curcas seeds or fruits. All patients experienced gastrointestinal disorders, within the first hours following ingestion: nausea, vomiting, diarrhea and abdominal pain. Laboratory investigations performed in 10 patients revealed minor abnormalities: CK elevation (8 cases), dehydration (5 cases) with moderate elevation of serum creatinine levels (3 cases), and mildly increased serum bilirubin (8 cases). Complete remission of all clinical signs was observed within 48 hours in the 20 cases for which the outcome was known. Previously published cases of J. curcas poisoning were very similar to ours: As in our series, gastrointestinal disorders were always present. They were sometimes associated with neurological or cardiovascular signs, and hepatic or renal disorders; these were generally interpreted as complications of severe gastroenteritis, although direct toxic effects could not be formally excluded. In most cases, simple supportive measures were sufficient to ensure complete recovery within 24-48 hours. J Curcas poisoning incidence is certainly increasing because the plant is cultivated to produce biodiesel and is now largely present in most subtropical countries. As a consequence, local health professionals should be informed of the toxic properties of this plant.

    The Reformed Teaching Observation Protocol (RTOP; Swada, et al., 2002) has been used by a trained team of On the Cutting Edge (CE) observers to characterize the degree of student-centered teaching in US college and university geoscience classrooms. Total RTOP scores are derived from scores on 25 rubric items used to characterize teaching practices in categories of lesson design, content delivery, student-instructor and student-student interactions. More than 200 classroom observations have been completed by the RTOP team in undergraduate courses at a variety of US institution types (e.g., community colleges, research universities). A balanced mix of early career, mid-career, and veteran faculty are included, and the study examines class sizes ranging from small (large (>80 students). Observations are limited to one class session and do not include laboratories or field activities. Data include RTOP scores determined by a trained observer during the classroom observation and an online survey in which the observed instructors report on their teaching practices. RTOP scores indicate that the observed geoscience classes feature varying degrees of student-centered teaching, with 30% of observed classes categorized as teacher-centered (RTOP scores ≤30), 45% of observed classes categorized as transitional classrooms (RTOP scores 31-49) and 25% are student-centered (RTOP scores ≥ 50). Instructor self-report survey data and RTOP scores indicate that geoscience faculty who have participated in one or more CE professional development event and use the CE website have an average RTOP score of 49, which is significantly higher (> 15 points) than the average score of faculty who have not participated in CE events and have not used the website. Approximately 60% of student-centered classes (those with high RTOP scores) use some traditional lecture nearly every day, but are also are likely to include an in-class activity or group discussion (e.g. Think-Pair-Share).

    Full Text Available One of the important learning objectives of our bachelor course on "Techniques in Decision Support Systems" is to develop understanding of core decision making process in real-life business situations. The conventional teaching methods are unable to explain complexities of real-life business. Although the classroom discussions can be effective to understand general factors, such as opportunity cost, return on investment, etc. affecting business decisions, the effects of factors like dynamic business environment, incomplete information, time pressure etc. can not be truly explained through such simple discussions. In this paper, we describe our experience of adopting student-centered, role-based, case study to deal with this situation. The interactive case-based study not only provided students with experiential learning, but also gave them liberty to test their thoughts. As a result, we observed improved students' learning as well as improved grades. In addition, this approach made classes more dynamic and interesting.

    We present theoretical results on the relationship between the rotational diffusion coefficient of a nanodiamond undergoing Brownian motion and the configuration of nitrogen vacancy centers (NVCs) contained in the particle. Through exact calculations and simulations, we obtain the fluorescence intensity autocorrelation function that is measured in optically detected magnetic resonance experiments conducted at single-particle level. We relate the autocorrelation function to the rotational diffusion coefficient and discuss the influence of different NVC configurations on the outcome of measurements. We believe that our results can be useful in interpreting observations on nanodiamonds that contain multiple nitrogen vacancy centers.

    Case study research is a comprehensive method that incorporates multiple sources of data to provide detailed accounts of complex research phenomena in real-life contexts. However, current models of case study research do not particularly distinguish the unique contribution observation data can make. Observation methods have the potential to reach beyond other methods that rely largely or solely on self-report. This article describes the distinctive characteristics of case study observational research, a modified form of Yin's 2014 model of case study research the authors used in a study exploring interprofessional collaboration in primary care. In this approach, observation data are positioned as the central component of the research design. Case study observational research offers a promising approach for researchers in a wide range of health care settings seeking more complete understandings of complex topics, where contextual influences are of primary concern. Future research is needed to refine and evaluate the approach.

    The Galactic center is an interesting region for high-energy (0.1-100 GeV) and very-high-energy (E > 100 GeV) gamma-ray observations. Potential sources of GeV/TeV gamma-ray emission have been suggested, e.g., the accretion of matter onto the supermassive black hole, cosmic rays from a nearby supernova remnant (e.g. SgrA East), particle acceleration in a plerion, or the annihilation of dark matter particles. The Galactic center has been detected by EGRET and by Fermi/LAT in the MeV/GeV energy band. At TeV energies, the Galactic center was detected with moderate significance by the CANGAROO and Whipple 10 m telescopes and with high significance by H.E.S.S., MAGIC, and VERITAS. We present the results from three years of VERITAS observations conducted at large zenith angles resulting in a detection of the Galactic center on the level of 18 standard deviations at energies above ~2.5TeV. The energy spectrum is derived and is found to be compatible with hadronic, leptonic and hybrid emission models discussed in the ...

    The Galactic center is an interesting region for high-energy (0.1-100 GeV) and very-high-energy (E > 100 GeV) γ-ray observations. Potential sources of GeV/TeV γ-ray emission have been suggested, e.g., the accretion of matter onto the supermassive black hole, cosmic rays from a nearby supernova remnant (e.g., Sgr A East), particle acceleration in a plerion, or the annihilation of dark matter particles. The Galactic center has been detected by EGRET and by Fermi/LAT in the MeV/GeV energy band. At TeV energies, the Galactic center was detected with moderate significance by the CANGAROO and Whipple 10 m telescopes and with high significance by H.E.S.S., MAGIC, and VERITAS. We present the results from three years of VERITAS observations conducted at large zenith angles resulting in a detection of the Galactic center on the level of 18 standard deviations at energies above ∼2.5 TeV. The energy spectrum is derived and is found to be compatible with hadronic, leptonic, and hybrid emission models discussed in the literature. Future, more detailed measurements of the high-energy cutoff and better constraints on the high-energy flux variability will help to refine and/or disentangle the individual models.

  19. Earth Observations to Assess Impact of Hurricane Katrina on John C. Stennis Space Center

    The peril from hurricanes to Space Operations Centers is real and is forecast to continue; Katrina, Rita, and Wilma of 2005 and Charley, Frances, Ivan, and Jeanne of 2004 are sufficient motivation for NASA to develop a multi-Center plan for preparedness and response. As was demonstrated at SSC (Stennis Space Center) in response to Hurricane Katrina, NASA Centers are efficiently activated as local command centers, playing host to Federal and State agencies and first responders to coordinate and provide evacuation, relocation, response, and recovery activities. Remote sensing decision support provides critical insight for managing NASA infrastructure and for assisting Center decision makers. Managers require geospatial information to manage the federal city. Immediately following Katrina, SSC s power and network connections were disabled, hardware was inoperative, technical staff was displaced and/or out of contact, and graphical decision support tools were non-existent or less than fully effective. Despite this circumstance, SSC EOC (Emergency Operations Center) implemented response operations to assess damage and to activate recovery plans. To assist Center Managers, the NASA ASP (Applied Sciences Program) made its archive of high-resolution data over the site available. In the weeks and months after the immediate crisis, NASA supplemented this data with high-resolution, post-Katrina imagery over SSC and much of the affected coastal areas. Much of the high-resolution imagery was made available through the Department of Defense Clear View contract and was distributed through U.S. Geological Survey Center for Earth Resources Observation and Science "Hurricane Katrina Disaster Response" Web site. By integrating multiple image data types with other information sources, ASP applied an all-source solutions approach to develop decision support tools that enabled managers to respond to critical issues, such as expedient access to infrastructure and deployment of resources

  20. Dark matter origin of the gamma ray emission from the galactic center observed by HESS

    Cembranos, J A R; Maroto, A L

    We show that the gamma ray spectrum observed with the HESS array of Cherenkov telescopes coming from the Galactic Center (GC) region and identified with the source HESS J1745-290, is well fitted by the secondary photons coming from dark matter (DM) annihilation over a diffuse power-law background. The amount of photons and morphology of the signal localized within a region of few parsecs, require compressed DM profiles as those resulting from baryonic contraction, which offer $\\sim 10^3$ enhancements in the signal over DM alone simulations. The fitted background from HESS data is consistent with recent Fermi-LAT observations of the same region.

    Ahern, T.; Benson, R.; Trabant, C.

    2009-04-01

    The Incorporated Research Institutions for Seismology (IRIS) is funded by the National Science Foundation (NSF) to operate the facilities to generate, archive, and distribute seismological data to research communities in the United States and internationally. The IRIS Data Management System (DMS) is responsible for the ingestion, archiving, curation and distribution of these data. The IRIS Data Management Center (DMC) manages data from more than 100 permanent seismic networks, hundreds of temporary seismic deployments as well as data from other geophysical observing networks such as magnetotelluric sensors, ocean bottom sensors, superconducting gravimeters, strainmeters, surface meteorological measurements, and in-situ atmospheric pressure measurements. The IRIS DMC has data from more than 20 different types of sensors. The IRIS DMC manages approximately 100 terabytes of primary observational data. These data are archived in multiple distributed storage systems that insure data availability independent of any single catastrophic failure. Storage systems include both RAID systems of greater than 100 terabytes as well as robotic tape robots of petabyte capacity. IRIS performs routine transcription of the data to new media and storage systems to insure the long-term viability of the scientific data. IRIS adheres to the OAIS Data Preservation Model in most cases. The IRIS data model requires the availability of metadata describing the characteristics and geographic location of sensors before data can be fully archived. IRIS works with the International Federation of Digital Seismographic Networks (FDSN) in the definition and evolution of the metadata. The metadata insures that the data remain useful to both current and future generations of earth scientists. Curation of the metadata and time series is one of the most important activities at the IRIS DMC. Data analysts and an automated quality assurance system monitor the quality of the incoming data. This insures data

    Laparoscopic splenectomy (LS) is nowadays considered as the gold standard for most hematological diseases where splenectomy is necessary, but many questions still remain. The aim of this study was to analyze our 5-years experiences consisting of 48 consecutive LS cases in order to assess the optimal approach and the feasibility of the procedure also in malignant diseases and unusual cases such as a primary spleen lymphoma, a big splenic artery aneurism, or a spleen infarct due to a huge pancreatic pseudo-cyst. Forty-eight consecutive patients underwent LS from January 2006 to January 2011 with at least 1-year follow-up. Clinical data and immediate outcome were retrospectively recorded; age, diagnosis, operation time, perioperative transfusion requirement, conversion rate, accessory incision, hospital stay, and complications were analyzed. We had 14 cases of malignant splenic disease, the most frequent malignant diagnosis was non-Hodgkin's lymphoma (12/14, 85.7 %). Splenomegaly (interpole diameter (ID) >20 cm) was observed in 12 cases (25 %) and massive splenomegaly (ID >25 cm) in 3 cases (6.25 %). Conversion to laparotomy occurred in two patients (4.16 %), both associated to uncontrollable bleeding in patients with splenomegaly. Mean operative time was 138 ± 22 min. Mean hospital stay was 4.5 days. Postoperative morbidity rate was 8.8 % for the benign group and 35.7 % in the malignant group. Mortality occurred in 1/48 patients (2.08 %), as a result of overwhelming post-splenectomy infection (OPSI). LS can be performed safely for malignant splenic disease and splenomegaly without any statistically significant increase of morbidity and mortality rate. Conversion rate is increased for massive splenomegaly. LS should be considered as the preferential approach even in patients with malignant disease, splenomegaly, or unusual cases. Massive splenomegaly should be considered as relative contraindication to LS even at experienced centers.

    2015-04-01

    The accumulative burden of a growing non-English speaking minority population and health disparities in the United States demonstrate the urgency of examining occupational therapy practices and defining care that is timely, effective, safe, and patient-centered. In this context, we investigate an occupational therapy episode of care from the perspectives of patient, caregiver, and primary occupational therapy care provider. Treatment sessions were observed and one-on-one semistructured interviews were conducted with the participants. Several themes describing areas of concern in communication and care delivery emerged, including expectations for care, the therapy relationship, professional identity, and pragmatic constraints. The use of untrained interpreters compromised treatment effectiveness and safety. This case highlights potential areas of concern in therapy when working with a diverse patient population. Abundant opportunities exist for occupational therapy to situate itself as an equitable, responsive, valuable, and essential service.

    2016-05-01

    Full Text Available Synthetic cannabinoid use has risen at alarming rates. This case series describes 11 patients exposed to the synthetic cannabinoid, MAB-CHMINACA who presented to an emergency department with life-threatening toxicity including obtundation, severe agitation, seizures and death. All patients required sedatives for agitation, nine required endotracheal intubation, three experienced seizures, and one developed hyperthermia. One developed anoxic brain injury, rhabdomyolysis and died. A significant number were pediatric patients. The mainstay of treatment was aggressive sedation and respiratory support. Synthetic cannabinoids pose a major public health risk. Emergency physicians must be aware of their clinical presentation, diagnosis and treatment.

    Mycetoma is a chronic granulomatous disease. It is classified into eumycetoma caused by fungi and actinomycetoma due to filamentous actinomycetes. Mycetoma can be found in geographic areas in close proximity to the Tropic of Cancer. Mexico is one of the countries in which this disease is highly endemic. In this retrospective study we report epidemiologic, clinical and microbiologic data of mycetoma observed in the General Hospital of Mexico in a 33 year-period (1980 to 2013). A total of 482 cases were included which were clinical and microbiology confirmed. Four hundred and forty four cases (92.11%) were actinomycetomas and 38 cases (7.88%) were eumycetomas. Most patients were agricultural workers; there was a male predominance with a sex ratio of 3:1. The mean age was 34.5 years old (most ranged from 21 to 40 years). The main affected localization was lower and upper limbs (70.74% and 14.52% respectively). Most of the patients came from humid tropical areas (Morelos, Guerrero and Hidalgo were the regions commonly reported). The main clinical presentation was as tumor-like soft tissue swelling with draining sinuses (97.1%). Grains were observed in all the cases. The principal causative agents for actinomycetoma were: Nocardia brasiliensis (78.21%) and Actinomadura madurae (8.7%); meanwhile, for eumycetomas: Madurella mycetomatis and Scedosporium boydii (synonym: Pseudallescheria boydii) were identified. This is a single-center, with long-follow up, cross-sectional study that allows determining the prevalence and characteristics of mycetoma in different regions of Mexico.

    Full Text Available Mycetoma is a chronic granulomatous disease. It is classified into eumycetoma caused by fungi and actinomycetoma due to filamentous actinomycetes. Mycetoma can be found in geographic areas in close proximity to the Tropic of Cancer. Mexico is one of the countries in which this disease is highly endemic. In this retrospective study we report epidemiologic, clinical and microbiologic data of mycetoma observed in the General Hospital of Mexico in a 33 year-period (1980 to 2013.

    The presence of OH (1720 MHz) masers, and the absence of counterparts at 1665/1667 MHz has proved to be a clear diagnostic of shocked molecular gas associated with Galactic supernova remnants. This suggests that shocked molecular gas should be associated with the OH (1720 MHz) masers that have been detected in the circumnuclear disk (CND) and Sgr A East at the Galactic center. In order to test this hypothesis, we observed the H$_2$ 1--0 S(1) and Br $\\gamma$ lines using NICMOS on the HST and UNSWIRF on the AAT, near the regions where OH (1720 MHz) masers are detected in the CND and Sgr A East. We present the distribution of H$_2$ in the North and South lobes of the CND and in Sgr A East. H$_2$ emission accompanies almost all of the maser spots detected at the Galactic center. In particular, we find a striking filamentary structure near the Northwest of the CND and evidence that shocked molecular gas is associated with the 70 \\kms molecular cloud at the Galactic center. We argue that the emission from the CND c...

    The Galactic center has some of the highest stellar densities in the Galaxy and a range of interstellar scattering properties that may aid in the detection of new radio-selected transient events. Here we describe a search for radio transients in the Galactic center using over 200 hours of archival data from the Very Large Array (VLA) at 5 and 8.4 GHz. Every observation of SgrA* from 1985$-$2005 has been searched using an automated processing and detection pipeline sensitive to transients with timescales between 30 seconds and five minutes with a typical detection threshold of $\\sim$100 mJy. Eight possible candidates pass tests to filter false-positives from radio-frequency interference, calibration errors, and imaging artifacts. Two events are identified as promising candidates based on the smoothness of their light curves. Despite the high quality of their light curves, these detections remain suspect due to evidence of incomplete subtraction of the complex structure in the Galactic center, and apparent cont...

    Full Text Available Background/Aim: Solitary rectal ulcer syndrome (SRUS is a benign, chronic defecation disorder with varied presentations. The aim of this study is to summarize the clinical features, endoscopic findings, histological appearance, and treatment strategies associated with SRUS. Patients and Methods: This is a retrospective study of all patients diagnosed with SRUS at the King Faisal Specialist Hospital and Research Centre in Riyadh from January 2003 to December 2013. Cases were identified using the Department of Pathology database. Data were obtained from medical records that included clinical manifestation, endoscopic findings, and histopathological features. Results: Twenty patients were identified. The mean age was 42.5 years (±18.5 and 55% were females. Most of the patients presented with bleeding per rectum (85%, constipation (75%, and straining (50%, with a mean symptom duration of 26.7 months. The most common associated factors identified were constipation (75%, history of rectal surgery (25%, digital rectal manipulation (20%, and rectal prolapse (20%. Endoscopic findings included a single ulcer (50% and multiple ulcers (30%; 55% had a polypoidal appearance. On histopathology, there was surface ulceration (95%, fibrosis of the lamina propria (60%, distorted architecture (55%, and muscle hypertrophy with increased mucin production (50%. Patients were treated conservatively and none required surgery. Conclusion: SRUS is a rare disorder with variable clinical presentations. Stool softeners, a high fiber diet in addition to topical mesalamine, and biofeedback proved to be effective in this patient population.

  14. Centering the Peripheral: A Case for Poetry in Africa

    Directory of Open Access Journals (Sweden)

    Joseph Muleka

    2014-01-01

    Full Text Available This paper grapples with a frequently asked question: Is there a case for poetry in Africa? Though not necessarily a polemical rooting for recognition of African oral poetry, the paper stands in contention with assertions that have tended to dismiss the said artworks as non-poetry, while at the same time attempting to confer superiority of the written poetry over the oral. In particular, the paper contests the arguments by some pioneer researchers into African literature that posited that what was usually touted as poetry in Africa did not qualify as true poetry, but rather, simply songs and chants. In an attempt to address the nitty-gritty of this subject the paper tackles the crucial question of what constitutes poetry and whether there is a significant difference between a song and a poem. The paper employs the theory of ethno-poetics which takes interest in the aesthetic components and poetic structuring of oral poems. Ethnopoetics gives guidelines on how to organize an oral text in lines to render its fullest charge of texture: rhythm, nuance, phrasing and other components that allow full poetic meaning. It is intended that the poetic restructuring will particularly help realize the poetic qualities in African poetic works. Besides, the paper also tries to popularize “narrato-centric” approach, an application we used earlier during a discussion on theory in the study of oral literature. The approach encourages the study of oral literature material that puts emphasis on performance and the dynamics dictating the performer and his role in the performance.

    The observed center-to-limb variation (CLV) of the scattering polarization in different lines of the Second Solar Spectrum can be used to constrain the height variation of various atmospheric parameters, in particular the magnetic fields via the Hanle effect. Here we attempt to model non-magnetic CLV observations of the $Q/I$ profiles of the Ca I 4227 A line recorded with the ZIMPOL-3 at IRSOL. For modeling, we use the polarized radiative transfer with partial frequency redistribution with a number of realistic 1-D model atmospheres. We find that all the standard FAL model atmospheres, used by us, fail to simultaneously fit the observed ($I$, $Q/I$) at all the limb distances ($\\mu$). However, an attempt is made to find a single model which can provide a fit at least to the CLV of the observed $Q/I$ instead of a simultaneous fit to the ($I$, $Q/I$) at all $\\mu$. To this end we construct a new 1-D model by combining two of the standard models after modifying their temperature structures in the appropriate heigh...

    2004-01-01

    We present the first center-to-limb G-band images synthesized from high resolution simulations of solar magneto-convection. Towards the limb the simulations show "hilly" granulation with dark bands on the far side, bright granulation walls and striated faculae, similar to observations. At disk center G-band bright points are flanked by dark lanes. The increased brightness in magnetic elements is due to their lower density compared with the surrounding intergranular medium. One thus sees deeper layers where the temperature is higher. At a given geometric height, the magnetic elements are cooler than the surrounding medium. In the G-band, the contrast is further increased by the destruction of CH in the low density magnetic elements. The optical depth unity surface is very corrugated. Bright granules have their continuum optical depth unity 80 km above the mean surface, the magnetic elements 200-300 km below. The horizontal temperature gradient is especially large next to flux concentrations. When viewed at an ...

    We report the diffuse X-ray emissions from the Sgr A and B regions observed with Suzaku. From the Sgr A region, we found many K-shell transition lines of iron and nickel. The brightest are K alpha lines from FeI, FeXXV and FeXXVI at 6.4 keV, 6.7 keV and 6.9 keV. In addition, K alpha lines of NiI and NiXXVII, K beta of FeI, FeXXV and FeXXVI, and K gamma of FeXXV and FeXXVI are detected for the first time. The center energy of K alpha of FeXXV favors collisional excitation as the origin for this line emission. The ionization temperature determined from the flux ratio of K alpha of FeXXV and FeXXVI is similar to the electron temperature determined from the flux ratio of K alpha and K beta of FeXXV, which are in the range of 5-7 keV. Consequently, the Galactic Center diffuse X-rays (GCDX) are consistent with emission from a plasma nearly in ionization equilibrium. The radio complex Sgr B region also exhibits K alpha lines of FeI, FeXXV and FeXXVI. The 6.7 keV line (FeXXV) map exhibits a local excess at (l,b) = (0...

    Care coordination is a core element of the Patient-Centered Medical Home and requires an effective, well educated nursing staff. A greater understanding of roles and tasks currently being carried out by nurses in primary care is needed to help practices determine how best to implement care coordination and transform into PCMHs. We conducted an observational study of primary care nursing in a Community Health Center by creating a classification schema for nursing responsibilities, directly observing and tracking nurses' work, and categorizing their activities. Ten nurses in eight different practice sites were observed for a total of 61 hours. The vast majority of nursing time was spent in vaccine and medication administration; telephone work; and charting and paper work, while only 15% of their time was spent in activity that was classified broadly as care coordination. Care coordination work appeared to be subsumed by other daily tasks, many of which could have been accomplished by other, lesser trained members of the health care team. Practices looking to implement care coordination need a detailed look at work flow, task assignments, and a critical assessment of staffing, adhering to the principal of each team member working to the highest level of his or her education and license. Care coordination represents a distinct responsibility that requires dedicated nursing time, separate from the day to day tasks in a busy practice. To fully support these new functions, reimbursement models are needed that support such non visit-based work and provide incentives to coordinate and manage complex cases, achieve improved clinical outcomes and enhance efficiency of the health system. This article describes our study methods, data collection, and analysis, results, and discussion about reorganizing nursing roles to promote care coordination.

  1. Infrared observations of the galactic center. I - Nature of the compact sources

    1978-01-01

    Photometry from 1.25 to 12 micrometers and spectrophotometry from 8 to 13 micrometers of the compact sources found in the galactic-center region are reported. In addition, revised 10 and new 20 micrometers maps with 2''.3 resolution are given. The nature of the compact sources is discussed. Some are best identified as stars or star clusters; the brightest source at 2 micrometers is probably a supergiant, and the infrared source near the nonthermal radio source is probably a stellar cluster with density greater than 1 million solar masses/cu pc. Other sources emit most of their luminosity at wavelengths of 10 micrometers and greater; this emission is probably from heated dust. One of the sources is observationally similar to extremely red OH/infrared stars. Other sources have luminosities and linear sizes similar to those of compact H II regions; emission from optically thin silicate dust is seen in these.

    In 2011, we discovered a compact gas cloud ("G2") with roughly three Earth masses that is falling on a near-radial orbit toward the massive black hole in the Galactic Center. The orbit is well constrained and pericenter passage is predicted for early 2014. Our data beautifully show that G2 gets tidally sheared apart due to the massive black hole's force. During the next months, we expect that in addition to the tidal effects, hydrodynamics get important, when G2 collides with the hot ambient gas around Sgr A*. Simulations show that ultimately, the cloud's material might fall into the massive black hole. Predictions for the accretion rate and luminosity evolution, however, are very difficult due to the many unknowns. Nevertheless, this might be a unique opportunity in the next years to observe how gas feeds a massive black hole in a galactic nucleus.

  4. Infrared-excess Source DSO/G2 Near the Galactic Center: Theory vs. Observations

    2015-01-01

    We monitored the Dusty S-cluster object (DSO/G2) during its closest approach to the Galactic Center supermassive black hole in 2014 with ESO VLT/SINFONI. We report on our findings, i.e. ionized-hydrogen emission from the DSO that remains spatially compact before and after the peribothron passage. The detection of DSO/G2 object as a compact single-peak emission line source is in contradiction with the original hypothesis of a core-less cloud that is necessarily tidally stretched, hence producing double-peak emission line profile around the pericentre passage. This strengthens the evidence that the DSO/G2 source is a dust-enshrouded young star. The accretion of material from the circumstellar disc onto the stellar surface can contribute significantly to the emission of Br$\\gamma$ line as well as to the observed large line width of the order of 10 angstroms.

    Since the early work by Ashkin in 1970, optical trapping has become one of the most powerful tools for manipulating small particles, such as micron sized beads or single atoms. The optical trapping mechanism is based on the interaction energy of a dipole and the electric field of the laser light. In atom trapping, the dominant contribution typically comes from the allowed optical transition closest to the laser wavelength, whereas for mesoscopic particles it is given by the bulk polarizability of the material. These two different regimes of optical trapping have coexisted for decades without any direct link, resulting in two very different contexts of applications: one being the trapping of small objects mainly in biological settings, the other one being dipole traps for individual neutral atoms in the field of quantum optics. Here we show that for nanoscale diamond crystals containing artificial atoms, so-called nitrogen vacancy (NV) color centers, both regimes of optical trapping can be observed at the same...

  6. Cosmological evolution of supermassive black holes in galactic centers unveiled by hard X-ray observations.

    2015-01-01

    We review the current understanding of the cosmological evolution of supermassive black holes in galactic centers elucidated by X-ray surveys of active galactic nuclei (AGNs). Hard X-ray observations at energies above 2 keV are the most efficient and complete tools to find "obscured" AGNs, which are dominant populations among all AGNs. Combinations of surveys with various flux limits and survey area have enabled us to determine the space number density and obscuration properties of AGNs as a function of luminosity and redshift. The results have essentially solved the origin of the X-ray background in the energy band below ∼10 keV. The downsizing (or anti-hierarchical) evolution that more luminous AGNs have the space-density peak at higher redshifts has been discovered, challenging theories of galaxy and black hole formation. Finally, we summarize unresolved issues on AGN evolution and prospects for future X-ray missions.

  7. SABRE observations of Pi2 pulsations: case studies

    Bradshaw, E. G.; Lester, M.

    1997-01-01

    The characteristics of substorm-associated Pi2 pulsations observed by the SABRE coherent radar system during three separate case studies are presented. The SABRE field of view is well positioned to observe the differences between the auroral zone pulsation signature and that observed at mid-latitudes. During the first case study the SABRE field of view is initially in the eastward electrojet, equatorward and to the west of the substorm-enhanced electrojet current. As the interval progresses, the western, upward field-aligned current of the substorm current wedge moves westward across the longitudes of the radar field of view. The westward motion of the wedge is apparent in the spatial and temporal signatures of the associated Pi2 pulsation spectra and polarisation sense. During the second case study, the complex field-aligned and ionospheric currents associated with the pulsation generation region move equatorward into the SABRE field of view and then poleward out of it again after the third pulsation in the series. The spectral content of the four pulsations during the interval indicate different auroral zone and mid-latitude signatures. The final case study is from a period of low magnetic activity when SABRE observes a Pi2 pulsation signature from regions equatorward of the enhanced substorm currents. There is an apparent mode change between the signature observed by SABRE in the ionosphere and that on the ground by magnetometers at latitudes slightly equatorward of the radar field of view. The observations are discussed in terms of published theories of the generation mechanisms for this type of pulsation. Different signatures are observed by SABRE depending on the level of magnetic activity and the position of the SABRE field of view relative to the pulsation generation region. A twin source model for Pi2 pulsation generation provides the clearest explanation of the signatures observed Acknowledgements. The authors are grateful to Prof. D. J. Southwood

    Meningococcal meningitis remains a periodical threat in the African meningitis belt. The countries concerned, such as Burkina Faso, provided guidelines for its surveillance, diagnosis, treatment, and prevention during outbreaks. The objective of this study is to assess the quality of the surveillance system and case management during an outbreak in Fada N'Gourma district. A retrospective study of the meningitis outbreak in 2007 was conducted by literature review and interviews of health caretakers across 27 health centers (CSPS) and three units in the regional hospital in the district.We reported all data available about surveillance and case management, and then we compared it with the guidelines of the Ministry of Health. The case definition and notification forms were available in all centers and units. During the outbreak, 861 cases were recorded, but only 89% was notified at the upper level and 87% of notification forms were available. The age is marked on all the forms, while the interval between the onset of symptoms and consultation is noted only in 90.7%. The forms were distributed weekly at the district level. Cerebrospinal fluid (CSF) Gram coloration was performed for a limited number of cases (150/349 samples, 42.9%); it showed Gram-negative diplococcus in 86%. Culture was performed for a limited number of patients (7 cases). According to the results of a central level laboratory study, the outbreak was due to Group A Neisseria meningitidis. The case management guidelines were available in all the centers and units which were supervised during the outbreak. Anti-biotherapy was appropriate in 93.6% of the cases. A shortage of antibiotics (free prepositioning) was observed in 7 centers (23.3%). The mortality rate was 3.5%. This assessment shows an under-notification of cases, despite the existence of a surveillance system and supervision, a weak laboratory contribution in germ identification, appropriate case management, and shortage of antibiotics during

    In this paper, we report radio observations of the Galactic Center magnetar PSR J1745–2900 at six epochs between 2014 June and October. These observations were carried out using the new Shanghai Tian Ma Radio Telescope at a frequency of 8.6 GHz. Both the flux density and integrated profile of PSR J1745–2900 show dramatic changes from epoch to epoch, showing that the pulsar was in its “erratic” phase. On MJD 56836, the flux density of this magnetar was about 8.7 mJy, which was 10 times larger than that reported at the time of discovery, enabling a single-pulse analysis. The emission is dominated by narrow “spiky” pulses that follow a log-normal distribution in peak flux density. From 1913 pulses, we detected 53 pulses whose peak flux densities are 10 times greater than that of the integrated profile. They are concentrated in pulse phase at the peaks of the integrated profile. The pulse widths at the 50% level of these bright pulses were between 0.°2 and 0.°9, much narrower than that of the integrated profile (∼12°). The observed pulse widths may be limited by interstellar scattering. No clear correlation was found between the widths and peak flux density of these pulses and no evidence was found for subpulse drifting. Relatively strong spiky pulses are also detected in the other five epochs of observation, showing the same properties as those detected in MJD 56836. These strong spiky pulses cannot be classified as “giant” pulses but are more closely related to normal pulse emission.

    Its peripheral vein puncture point, safe insertion procedure and high rate of success have made the peripherally inserted central catheter (PICC) a particularly suitable medical device for cancer patients who require long-term intravenous chemotherapy. PICC can help avoid the pain of repeat punctures as well as reduce incidence of cytotoxic drug extravasation-induced phlebitis and tissue necrosis. With PICC, patient activity is not limited, which improves quality of life. This paper reported on complications and subsequent nursing care provided to 400 cancer patients who received PICC in our center between September 2007 and October 2008. A total of 395 cases had successful PICC insertion on the first attempt and 5 cases achieved success immediately following the second insertion attempt (overall success rate: 98.8%). The average catheter dwell-in time was 122 days (range 2-350 days), during which time no patient required repeat puncture. During the insertion process, arrhythmia occurred in 1.5% (6/400), difficult catheter propelling in 3.75% (15/400), and excessive oozing of blood in 0.3% (1/400) of subjects. During the catheter dwell-in period, sensitizing dermatitis occurred in 8% (38/400), mechanical phlebitis in 7.5% (30/400), catheter occlusion in 9.5% (38/400) (including 2% [8/400] complete and 7.5% [30/400] partial occlusions), catheter associated hematogenous infection in 3% (12/400) and venous thrombosis in 2% (8/400) of subjects. All complications were well controlled with active and effective management. In conclusion, the safety of PICC can be maximized and complications reduced when nurses fully evaluate patients prior to their operation, strictly adhere to PICC operating guidelines, detect complications early, and manage problems promptly.

    To provide retrospective, descriptive information on patients with cervical necrotizing fasciitis treated at a single center during the years 1998-2014, and to evaluate the outcome of a newly introduced treatment strategy. Retrospective analysis of clinical data obtained from medical records. Mortality, pre-morbidity, severity of illness, primary site of infection, type of bacteria, time parameters. The observed 3-month mortality was 6/59 (10 %). The most common initial foci of the infection were pharyngeal, dental or hypopharyngeal. The most common pathogen was Streptococcus milleri bacteria within the Streptococcus anginosus group (66 % of the cases). Using a combined treatment with early surgical debridement combined with hyperbaric oxygen treatment, it is possible to reduce the mortality rate among patients suffering from cervical necrotizing fasciitis, compared to the expected mortality rate and to previous historical reports. Data indicated that early onset of hyperbaric oxygen treatment may have a positive impact on survival rate, but no identifiable factor was found to prognosticate outcome.

    2015-01-01

    The traditional medical care system is generally unable to provide the broad health and wellness services needed by many adolescents, especially those from low-income and racial/ethnic minority communities. Using a theoretical framework adapted from Bronfenbrenner's ecological model of multiple influencers, this case study examined how a school-based health center was able to provide a network of connections for adolescents to caring adults within the school and the local community. Contributors to this network were the creation of a student-centered community with access to adolescent-friendly services, providers acting as connectors, and care of the whole adolescent.

  18. Center-to-Limb Variation of Solar Granulation from Partial Eclipse Observations

    2000-08-01

    We have measured the center-to-limb variation (CLV) of parameters describing geometric and photometric statistical properties of the solar granulation at 6708 Å. This work is based on an excellent series of white-light images obtained with the Swedish Vacuum Solar Telescope at Roque de los Muchachos Observatory, La Palma, during the partial solar eclipse of 1994 May 10. The lunar limb profile, which is visible in each frame, was used as a calibration tool for estimating the point-spread function of the combined optical system formed by the atmosphere and the telescope. Before restoration, noise was removed from the images by a novel application of the so-called optimum filter for two-dimensional objects. The latter was optimized in terms of rms error and was constructed from very precise smoothed models of the specific power spectrum of the granulation at each position on the solar disk. The determination of the positions on the solar disk was achieved with high accuracy by matching the position of the Moon's limb in our images to a numerical simulation of the eclipse geometry. The CLV curve of the ΔIrms granular contrast shows one of the steepest gradients among those reported in the literature and quite a high value (9.6%) at the disk center considering that our working wavelength is in the far-red range of the solar spectrum. The elliptical shape of the restored power spectra with ellipticities equal to those expected just from foreshortening proves that radiative transfer effects do not alter the isotropy of the horizontal intensity pattern of the solar granulation, at least up to μ=0.4. The mean wavenumber, k, derived from the two-dimensional power spectra azimuthally integrated along the ellipses amounts to a value of 6.15 Mm-1 at the center of the solar disk and then shows a decrease toward the limb. Apart from the power spectra analysis, a direct statistical study of the granulation size and brightness, based on the image segmentation for defining

    According to the World Meteorological Organization (WMO) Global Atmosphere Watch (GAW) Strategic Plan: 2008-2015 (WMO, 2009a) WMO/GAW pays attention to systematical improvement of the quality of observations at global or regional monitoring sites. To ensure the comparability and compatibility of the measurements worldwide it is essential to maintain a traceability chain to the primary standard in the different laboratories around the world as well as to establish a quality control system. Sulfur hexafluoride (SF6), is reported to be very rare in the atmosphere at the global averaged annual mole fraction of about 7 ppt, it is one of the greenhouse gases regulated by Kyoto protocol and is increasing at a rate of 0.22 ppt yr-1. Development of a working (or transfer) standard with very low concentration of SF6 requires expert technologies and several knowhow of gas metrology. In order to meet the Data Quality Objective (DQO), the KMA has cooperated with the Korea Research Institute of Standards and Science (KRISS), which is the National Metrology Institute in South Korea. So long as the Central Calibration Laboratory (CCL) for SF6 was established, the Korea Meteorological Administration (KMA) is now trying to take another step forward to systematically support GAW stations in improving their traceability and quality system for SF6, thereby making a contribution to the WMO/GAW. Through hosting the World Calibration Center for SF6, which is one of GAW facilities, KMA will contribute to harmonization of the global SF6 observations in the long run. This work performed to demonstrate some measurement results on SF6 which complies with the DQOs and is traceable to the WMO mole fraction scale for SF6. In order to produce a working standard which is traceable to the WMO scale, we developed highly precise method of a Gas Chromatography/Electron Capture Detector (GC/ECD) calibrated against the five cylinders (from NOAA, 2011) of the WMO scale.

  2. Massive vectors and loop observables: the $g-2$ case

    Biggio, Carla; Di Luzio, Luca; Ridolfi, Giovanni

    2016-01-01

    We discuss the use of massive vectors for the interpretation of some recent experimental anomalies. In order for loop observables, such as for example the muon $g-2$, to be finite (and hence to be predictable in terms of a renormalizable Lagrangian) the massive vector must be embedded into a spontaneously broken extended gauge symmetry. The latter, however, typically imposes strong constraints on the mass of the new vector boson and for the muon $g-2$ it basically rules out, barring the case of abelian gauge extensions, the explanation of the discrepancy in terms of a single vector extension of the standard model. We finally comment on the use of massive vectors for $B$-meson decay and di-photon anomalies.

    1997-01-01

    We describe a first attempt to apply adaptive optics to the study of resolved stellar populations in galaxies. Advantages over traditional approaches are (i) improved spatial resolution and point-source sensitivity through adaptive optics, and (ii) use of the near-infrared region, where the peak of the spectral energy distribution for old populations is found. Disadvantages are the small area covered and the need for excellent seeing. We made observations with the ADONIS system at the European Southern Observatory of the peculiar elliptical galaxy NGC 5128; the irregular galaxy IC 5152 (a possible outer member of the Local Group); the Sc galaxy NGC 300 (a member of the Sculptor group); and the Sgr window in the bulge of the Milky Way. These different fields give excellent test cases for the potential of adaptive optics. In the first two cases, we failed to obtain photometry of individual stars, which would have required excellent seeing. For NGC 300 we measured magnitudes for nine individual supergiants (H = ...

    Native Science Field Centers (NSFCs) were created to engage youth and adults in environmental science activities through the integration of traditional Native ways of knowing (understanding about the natural world based on centuries of observation including philosophy, worldview, cosmology, and belief systems of Indigenous peoples), Native languages, and Western science concepts. This paper focuses on the Blackfeet Native Science Field Center, the Lakota Native Science Field Center, and the Wind River Native Science Field Center. One of the long-term, overarching goals of these NSFCs was to stimulate the interest of Native American students in ways that encouraged them to pursue academic and career paths in science, technology, engineering, and mathematics (STEM) fields. A great deal can be learned from the experiences of the NSFCs in terms of effective educational strategies, as well as advantages and challenges in blending Native ways of knowing and Western scientific knowledge in an informal science education setting. Hopa Mountain—a Bozeman, Montana-based nonprofit—partnered with the Blackfeet Community College on the Blackfeet Reservation, Fremont County School District #21 on the Wind River Reservation, and Oglala Lakota College on the Pine Ridge Reservation to cooperatively establish the Native Science Field Centers. This paper presents a profile of each NSFC and highlights their program components and accomplishments.

  5. Relation of people-centered public health and person-centered healthcare management: a case study to reduce burn-out.

    Healthcare management is one practical tool for mediation and implementation of public health into clinical healthcare outcomes and is taken in our case study as an exemplar arena to demonstrate the vital importance of the person-centered approach. Healthcare personnel are frequently at risk for the 'burn-out' syndrome. However, modern measures of burn-out recognize burn-out only at a late stage when it is fully developed. There are no available methods to assess the risk for vulnerability to burnout in healthcare systems. Our aim was therefore to design a complex person-centered model for detection of high risk for burn-out at an early stage, that has been termed 'flame-out'. We accept the observation that decreased personal performance is one crucial expression of burn-out. Low personal performance and negative emotions are strongly related to low self-directedness as measured by the Temperament and Character Inventory (TCI). At the same time, burn-out is characterized by decreased interest and positive emotions from work. Decreased positive emotion is directly related to low self-transcendence as measured by the TCI. Burn-out is also frequently associated with feelings of social alienation or inadequacy of support, which is in turn related to low TCI Cooperativeness. However, high Persistence and Harm Avoidance are predisposing traits for burn-out in healthcare professionals who are often overly perfectionistic and compulsive, predisposing them to anxiety, depression, suicide and burn-out. Hence, people at risk for future burn-out are often highly conscientious over-achievers with intense mixtures of positive and negative emotions. The high demand for perfection comes from both intrinsic characteristics and from features of the social milieu in their psychological climate. Letting go of the unfulfillable desire to be perfect by increasing self-transcendence allows acceptance of the imperfection of the human condition, thereby preventing burn-out and other

    Retrospective investigations of odontomas in Japanese children and one recurrent case were carried out. Thirty-nine cases of odontoma in 38 children were treated in the Paediatric Dentistry Clinic of Niigata University Dental Hospital between September 1979 and December 2002. The patients consisted of 23 males and 15 females and their ages ranged from 1 year 2 months to 14 years old. The chief complaints were delayed tooth eruption in 19 cases (five: primary teeth, 14: permanent teeth), retention of primary teeth in 11, incidentally found on the radiographic examination in eight cases, and swelling of the jaw in one case. Thirty-four cases (87%) were associated with tooth eruption disturbances. The most frequently affected region was the maxillary anterior region. Treatment consisted of surgical removal of odontomas in all cases, after which if the impacted teeth did not erupt, exposure of the crown and/or orthodontic traction was performed. Pathological diagnoses were compound odontoma in 30 cases, complex odontoma (n = 7), and compound and complex odontoma (n = 2). A retrospective study of the radiographs revealed the developing process of odontomas in four cases and odontoma disturbed tooth eruption since the early uncalcified developing stage. A recurrent case was a boy aged 6 years 5 months in whom the first surgical removal of odontoma was performed at the age of 1 year 8 months. Recurrence of an odontoma is very rare, but in very young children odontomas are in the early developing stages, containing uncalcified portions, so it is important to perform periodical observations until the succedaneous teeth erupt.

This multicenter, epidemiological 3-month follow-up study investigates pain management efficacy in Spanish centers using patient satisfaction criteria. 3,414 eligible adult patients (65,6% female with moderate to severe chronic pain from 146 pain centers were included. Patient satisfaction was assessed based onto question 18 of Spanish healthcare barometer-CSI. Pain evolution (Brief Pain Inventory-Short Form (BPI-SF and visual analog scale (VAS, quality of life/EuroQol-5, and pain control expectations fulfillment were also assessed. Mean age was 61.3 years. 64.4% of participating centers employed multidisciplinary pain management approach. After 3 months, mean patient satisfaction was 7.8 (1–10 on the CIS barometer. Medical staff received the highest scores, whereas waiting for tests, appointment request to appointment date time, and waiting times at the center the lowest. Mean pain decreased from 7.4 to 4.0; BPI-SF intensity decreased from 6.5 to 3.8; pain control expectations were met in 78.7% of patients; EuroQoL-5D utility index increased from 0.37 to 0.62, p<0.001, and health status (VAS from 40.6 to 61.9, p<0.001. Chronic pain patients (90% are satisfied with Spanish centers care; 80% had their pain control expectations met. Quality of life improved remarkably: 71% felt moderately to significantly better.

    2002-10-01

    Full Text Available There exists empirical evidence proving that students who are given the freedom to explore areas based on their personal interests, and who are accompanied in their learning by a supportive, understanding facilitator, not only achieve superior academic results but also develop socially and grow personally. However, pure Student-Centered Teaching is more demanding in terms of communication, organization, as well as the provision of learning material. Thus, the basic idea underlying our paradigm is to combine Student-Centered Teaching with eLearning in order to exploit the advantages of the two approaches. We refer to this combined style as Student-Centered eLearning (SCeL. Strongly simplified, the computer takes over the task of providing information, while presence phases can be used for giving the content more meaning by means of transparent, open, respectful and empathic interactions within the group. Our case study indicates that Student-Centered eLearning has the potential of reducing the increased demands of Student-Centered Teaching in the long run, while fully retaining all its benefits, such as deeper learning processes, personal growth, social skills, and a higher degree of flexibility. Furthermore, the maturity for life-long learning is cultivated. In this paper we introduce our concept and derive first hypotheses on the conditions under which our paradigm appears most effective. While potential continuations of our studies are manifold, we intend to employ SCeL in the course of the new curriculum of the medical faculty of GrazUniversity where a Virtual Medical Campus (http://vmc.uni-graz.at is currently being developed.

    2015-12-01

    When hazards are known it is not a question of if but when the disaster shock will happen and it is critical that all relevant observational data, tools and technologies be accessible and integrated by experts and volunteers to provide reliable, timely and actionable information. In this talk NASA's coordinated response to the recent Nepal "Gorkha" will be presented as a case study to highlight the opportunities and challenges. Triggered by a global seismic network and the interpretation by operational, research and response agencies, all available assets were quickly mobilized, charters activated to share data, and information gathered to assess impacts. This included assessing available data from optical and radar-based satellites and global positioning systems to baseline pre-event conditions and distinguish immediate and ongoing changes. Models and maps were generated to identify land deformation and damage proxies for communities, resources and infrastructure. Technologies facilitated national and international collaboration among public and private sector institutions to task satellites and optimize integration and processing of data from vital airborne platforms or ingest relevant new data streams. Crowd-sourced data added to the mix and provided a critical source of ground truth that blended with reports from field teams and those in communities. New levels of situational awareness were achieved through integrated data products and the reliance on relationships and new technologies that allowed for volunteers to analyze results in an unprecedented fashion. The results demonstrated how science aided by emerging technologies is changing our implementation of disaster response.

    The diagnosis of inflammatory breast cancer (IBC) is largely clinical and therefore inherently somewhat subjective. The objective of this study was to evaluate the diagnosis of IBC at two centers in North Africa where a higher proportion of breast cancer is diagnosed as IBC than in the United States (U.S.). Physicians prospectively enrolled suspected IBC cases at the National Cancer Institute (NCI) - Cairo, Egypt, and the Institut Salah Azaiz (ISA), Tunisia, recorded extent and duration of signs/symptoms of IBC on standardized forms, and took digital photographs of the breast. After second-level review at study hospitals, photographs and clinical information for confirmed IBC cases were reviewed by two U.S. oncologists. We calculated percent agreement between study hospital and U.S. oncologist diagnoses. Among cases confirmed by at least one U.S. oncologist, we calculated median extent and duration of signs and Spearman correlations. At least one U.S. oncologist confirmed the IBC diagnosis for 69% (39/50) of cases with photographs at the NCI-Cairo and 88% (21/24) of cases at the ISA. All confirmed cases had at least one sign of IBC (erythema, edema, peau d'orange) that covered at least one-third of the breast. The median duration of signs ranged from 1 to 3 months; extent and duration of signs were not statistically significantly correlated. From the above-mentioned outcomes, it can be concluded that the diagnosis of a substantial proportion of IBC cases is unambiguous, but a subset is difficult to distinguish from other types of locally advanced breast cancer. Among confirmed cases, the extent of signs was not related to delay in diagnosis.

    T-cell or natural killer (NK)-cell posttransplant lymphoproliferative disorder (T-PTLD) is a rare but severe complication after transplant. Here we present the clinicopathological features of a single-center series of nine cases. Additionally, we summarize the clinicopathological findings of 147 cases of T/NK-cell PTLD reported in the literature in an attempt to define subtype-specific characteristics. T/NK-cell PTLD occurs in patients of all ages, usually extranodally, and most frequently after kidney transplant. Organ specific incidence, however, is highest following heart transplant. Approximately one-third of T-cell PTLDs are Epstein-Barr virus (EBV)-related, with peripheral T-cell lymphoma, not otherwise specified (PTCL, NOS) being the most prevalent EBV-associated T-cell PTLD. A male predominance is observed, which is most striking in the EBV(+) group, particularly in PTCL, NOS. With a median posttransplant interval of 72 months, T-cell PTLDs are among the late-occurring PTLDs. Of the most common T-cell PTLDs, anaplastic large cell lymphoma (ALCL) has the best prognosis, whereas PTCL, NOS and hepatosplenic T-cell lymphoma (HSTCL) have the worst prognosis. EBV(+) cases seem to have a longer survival than EBV(-) cases, suggesting a different pathogenetic mechanism.

    Sparse aperture masking (SAM) interferometry combined with Adaptive Optics (AO) is a technique that is uniquely suited to investigate structures near the diffraction limit of large telescopes. The strengths of the technique are a robust calibration of the Point Spread Function (PSF) while maintaining a relatively high dynamic range. We used SAM+AO observations to investigate the circumstellar environment of several bright sources with infrared excess in the central parsec of the Galaxy. For our observations, unstable atmospheric conditions as well as significant residuals after the background subtraction presented serious problems for the standard approach of calibrating SAM data via interspersed observations of reference stars. We circumvented these difficulties by constructing a synthesized calibrator directly from sources within the field-of-view. When observing crowded fields, this novel method can boost the efficiency of SAM observations because it renders interspersed calibrator observations unnecessary. Here, we presented the first NaCo/SAM images reconstructed using this method.

    We report a possible detection of TeV gamma-rays from the Galactic Center by the Whipple 10m gamma-ray telescope. Twenty-six hours of data were taken over an extended period from 1995 through 2003 resulting in a total significance of 3.7 standard deviations. The measured excess corresponds to an integral flux of \\Flux above an energy of $2.8 \\mathrm{TeV}$, roughly 40% of the flux from the Crab Nebula at this energy. The 95% confidence region has an angular extent of about 15 arcmin and includes the position of Sgr A*. The detection is consistent with a point source and shows no evidence for variability.

    2011-12-01

    Services that preserve and enable future access to scientific data are necessary to ensure that the data that are being collected today will be available for use by future generations of scientists. Many data centers, archives, and other digital repositories are working to improve their ability to serve as long-term stewards of scientific data. Trust in sustainable data management and preservation capabilities of digital repositories can influence decisions to use these services to deposit or obtain scientific data. Building on the Open Archival Information System (OAIS) Reference Model developed by the Consultative Committee for Space Data Systems (CCSDS) and adopted by the International Organization for Standardization as ISO 14721:2003, new standards are being developed to improve long-term data management processes and documentation. The Draft Information Standard ISO/DIS 16363, "Space data and information transfer systems - Audit and certification of trustworthy digital repositories" offers the potential to evaluate digital repositories objectively in terms of their trustworthiness as long-term stewards of digital resources. In conjunction with this, the CCSDS and ISO are developing another draft standard for the auditing and certification process, ISO/DIS 16919, "Space data and information transfer systems - Requirements for bodies providing audit and certification of candidate trustworthy digital repositories". Six test audits were conducted of scientific data centers and archives in Europe and the United States to test the use of these draft standards and identify potential improvements for the standards and for the participating digital repositories. We present a case study of the test audit conducted on the NASA Socioeconomic Data and Applications Center (SEDAC) and describe the preparation, the audit process, recommendations received, and next steps to obtain certification as a trustworthy digital repository, after approval of the ISO/DIS standards.

    Fukui et al. (2006) discovered two molecular loops in the Galactic center that are likely created by the magnetic flotation due to the Parker instability. Following the discovery, we present here a detailed study of the two loops based on NANTEN 12CO(J=1-0) and 13CO(J=1-0) datasets. The two loops are located in (l, b) ~ (357, 1) deg. at a velocity range of -20 - -180 km/s with a projected total length of ~ 600 pc and heights of ~250 - 300 pc from the Galactic disk at a distance of 8.5 kpc. They show bright foot points in the 12CO emission in the edges of the loops at b ~ 0.8 - 1.0 deg.. These foot points are characterized by velocity dispersions of 50 - 100 km/s. The loops also show large-scale velocity gradients of ~30 - 50 km/s per ~100 pc. The loops also have counterparts of the HI gas and IRAS emissions. The HI gas with weaker intensity fills the inner part of the loops where there is no significant 12CO and 13CO emission. We estimate total mass and kinetic energy of the loops are ~1.5 - 2.5 x 10^6 Msun a...

    The Fermi Large Area Telescope (LAT) has provided the most detailed view to date of the emission toward the Galactic center (GC) in high-energy γ-rays. This paper describes the analysis of data taken during the first 62 months of the mission in the energy range 1–100 GeV from a 15° × 15° region about the direction of the GC. Specialized interstellar emission models (IEMs) are constructed to enable the separation of the γ-ray emissions produced by cosmic ray particles interacting with the interstellar gas and radiation fields in the Milky Way into that from the inner ∼1 kpc surrounding the GC, and that from the rest of the Galaxy. A catalog of point sources for the 15° × 15° region is self-consistently constructed using these IEMs: the First Fermi-LAT Inner Galaxy Point Source Catalog (1FIG). The spatial locations, fluxes, and spectral properties of the 1FIG sources are presented, and compared with γ-ray point sources over the same region taken from existing catalogs. After subtracting the interstellar emission and point-source contributions a residual is found. If templates that peak toward the GC are used to model the positive residual the agreement with the data improves, but none of the additional templates tried account for all of its spatial structure. The spectrum of the positive residual modeled with these templates has a strong dependence on the choice of IEM.

    Phase-change memory based on Ti0.4Sb2Te3 material has one order of magnitude faster Set speed and as low as one-fifth of the Reset energy compared with the conventional Ge2Sb2Te5 based device. However, the phase-transition mechanism of the Ti0.4Sb2Te3 material remains inconclusive due to the lack of direct experimental evidence. Here we report a direct atom-by-atom chemical identification of titanium-centered octahedra in crystalline Ti0.4Sb2Te3 material with a state-of-the-art atomic mapping technology. Further, by using soft X-ray absorption spectroscopy and density function theory simulations, we identify in amorphous Ti0.4Sb2Te3 the titanium atoms preferably maintain the octahedral configuration. Our work may pave the way to more thorough understanding and tailoring of the nature of the Ti-Sb-Te material, for promoting the development of dynamic random access memory-like phase-change memory as an emerging storage-class memory to reform current memory hierarchy.

    The rapidly escalating cost of health care, including the cost of providing health care benefits, is a significant concern for many employers. In this article, the authors examine a case study of an academic health center that undertook a complete redesign of its health benefit structure to control rising costs, encourage use of its own provider network, and support employee wellness. With the implementation in 2006 of a high-deductible health plan combined with health reimbursement arrangements and wellness incentives, the Penn State Hershey Medical Center (PSHMC) was able to realize significant cost savings and increase use of its own network while maintaining a high level of employee satisfaction. By contracting with a single third-party administrator for its self-insured plan, PSHMC reduced its administrative costs and simplified benefit choices for employees. In addition, indexing employee costs to salary ensured that this change was equitable for all employees, and the shift to a consumer-driven health plan led to greater employee awareness of health care costs. The new health benefit plan's strong focus on employee wellness and preventive health has led to significant increases in the use of preventive health services, including health risk assessments, cancer screenings, and flu shots. PSHMC's experience demonstrates the importance of clear and ongoing communication with employees throughout--before, during, and even after--the process of health benefit redesign.

  8. Analysis of the Service Quality of Medical Centers Using Servqual Model (Case:Shaheed Rahnemoon Hospital

    2007-07-01

    Full Text Available Introduction: Many organizations, especially service oriented ones, relative to their goals and mission, have a special view towards quality phenomena and its management. Methods: This paper analyzes medical service quality in one case; The internal section of Shaheed Rahnemoon Hospital Based on the basis of gap analysis model and Servqual technique. A questionnaire was designed and applied to measure expectations and perceptions of patients and personnel of the hospital. Results: On application of non-parametric statistical tests, we propose certain recommendations. These tests drive on five conceptual dimensions of service quality including intangibility, responsiveness, reliability, assurance and empathy. Results show that patients in this section were satisfied from the service provider’s responsiveness, but there are significant differences between expectations and perceptions in other dimensions. Conclusion: The service quality analysis models are useful for managers of medical centers to distinguish gaps between the two sides of service representation; patients and medical centers personnel. Ultimately, they can reinforce strengths and control weaknesses.

    Childhood-onset cluster headache is an excruciatingly painful and distressing condition. A retrospective study was conducted on charts of patients referring to our Headache Center. Those diagnosed as cluster headache were selected. We identified 11 children (6 males and 5 females). The mean age of cluster headache onset was 10 years (range: 5-16). All children had episodic cluster headache. All children had unilateral orbital pain; 7 patients had throbbing pain, whereas 4 children complained stabbing pain. The mean duration of the attack was 86 minutes (ranging from 30 to 180 minutes). The frequency of episodes was between 1 and 4 per day. All children had the typical cluster headache autonomic features, such as lacrimation, conjunctival injection, ptosis, and nostril rhinorrhea. Steroids showed a good clinical efficacy in interrupting cluster headache recurrence. As symptomatic drugs, acetaminophen as well as ibuprofen were ineffective; indomethacin was effective in 1 case.

  10. Lyme Neuroborreliosis: Preliminary Results from an Urban Referral Center Employing Strict CDC Criteria for Case Selection

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available Lyme neuroborreliosis or “neurological Lyme disease” was evidenced in 2 of 23 patients submitted to strict criteria for case selection of the Centers for Disease Control and Prevention employing a two-tier test to detect antibodies to Borrelia burgdorferi at a single institution. One patient had symptomatic polyradiculoneuritis, dysautonomia, and serological evidence of early infection; and another had symptomatic small fiber sensory neuropathy, distal polyneuropathy, dysautonomia, and serological evidence of late infection. In the remaining patients symptoms initially ascribed to Lyme disease were probably unrelated to B. burgdorferi infection. Our findings suggest early susceptibility and protracted involvement of the nervous system most likely due to the immunological effects of B. burgdorferi infection, although the exact mechanisms remain uncertain.

  11. Observational evidences for the existence of 17.4 keV decaying degenerate sterile neutrinos near the Galactic Center

    CERN Document Server

    Chan, Man Ho

    2010-01-01

    We show that the existence of a degenerate halo of sterile neutrinos with rest mass of 17.4 keV near the Galactic Center can account for both the excess 8.7 keV emission observed by the $Suzaku$ mission and the power needed ($10^{40}$ erg s$^{-1}$) to maintain the high temperature of the hot gas (8 keV) near the Galactic Center. The required decay rate and mixing angle of the sterile neutrinos are $\\Gamma \\ge 5 \\times 10^{-20}$ s$^{-1}$ and $\\sin^22 \\theta \\sim 10^{-3}-10^{-4}$ respectively. These values are consistent with a low reheating temperature in the inflation model, and suggest the exciting possibility that the sterile - active neutrino oscillation can be visible in near future experiments.

  12. Statistical Machines for Trauma Hospital Outcomes Research: Application to the PRospective, Observational, Multi-Center Major Trauma Transfusion (PROMMTT Study.

    Directory of Open Access Journals (Sweden)

    Sara E Moore

    Full Text Available Improving the treatment of trauma, a leading cause of death worldwide, is of great clinical and public health interest. This analysis introduces flexible statistical methods for estimating center-level effects on individual outcomes in the context of highly variable patient populations, such as those of the PRospective, Observational, Multi-center Major Trauma Transfusion study. Ten US level I trauma centers enrolled a total of 1,245 trauma patients who survived at least 30 minutes after admission and received at least one unit of red blood cells. Outcomes included death, multiple organ failure, substantial bleeding, and transfusion of blood products. The centers involved were classified as either large or small-volume based on the number of massive transfusion patients enrolled during the study period. We focused on estimation of parameters inspired by causal inference, specifically estimated impacts on patient outcomes related to the volume of the trauma hospital that treated them. We defined this association as the change in mean outcomes of interest that would be observed if, contrary to fact, subjects from large-volume sites were treated at small-volume sites (the effect of treatment among the treated. We estimated this parameter using three different methods, some of which use data-adaptive machine learning tools to derive the outcome models, minimizing residual confounding by reducing model misspecification. Differences between unadjusted and adjusted estimators sometimes differed dramatically, demonstrating the need to account for differences in patient characteristics in clinic comparisons. In addition, the estimators based on robust adjustment methods showed potential impacts of hospital volume. For instance, we estimated a survival benefit for patients who were treated at large-volume sites, which was not apparent in simpler, unadjusted comparisons. By removing arbitrary modeling decisions from the estimation process and concentrating

  14. Personality traits affect teaching performance of attending physicians: results of a multi-center observational study.

    Directory of Open Access Journals (Sweden)

    Renée A Scheepers

    Full Text Available BACKGROUND: Worldwide, attending physicians train residents to become competent providers of patient care. To assess adequate training, attending physicians are increasingly evaluated on their teaching performance. Research suggests that personality traits affect teaching performance, consistent with studied effects of personality traits on job performance and academic performance in medicine. However, up till date, research in clinical teaching practice did not use quantitative methods and did not account for specialty differences. We empirically studied the relationship of attending physicians' personality traits with their teaching performance across surgical and non-surgical specialties. METHOD: We conducted a survey across surgical and non-surgical specialties in eighteen medical centers in the Netherlands. Residents evaluated attending physicians' overall teaching performance, as well as the specific domains learning climate, professional attitude, communication, evaluation, and feedback, using the validated 21-item System for Evaluation of Teaching Qualities (SETQ. Attending physicians self-evaluated their personality traits on a 5-point scale using the validated 10-item Big Five Inventory (BFI, yielding the Five Factor model: extraversion, conscientiousness, neuroticism, agreeableness and openness. RESULTS: Overall, 622 (77% attending physicians and 549 (68% residents participated. Extraversion positively related to overall teaching performance (regression coefficient, B: 0.05, 95% CI: 0.01 to 0.10, P = 0.02. Openness was negatively associated with scores on feedback for surgical specialties only (B: -0.10, 95% CI: -0.15 to -0.05, P<0.001 and conscientiousness was positively related to evaluation of residents for non-surgical specialties only (B: 0.13, 95% CI: 0.03 to 0.22, p = 0.01. CONCLUSIONS: Extraverted attending physicians were consistently evaluated as better supervisors. Surgical attending physicians who display high levels of

    We present the results of a 55 ks NuSTAR observation of the core of the Coma Cluster. The global spectrum can be explained by thermal gas emission, with a conservative 90% upper limit to non-thermal inverse Compton (IC) emission of 5.1 × 10{sup –12} erg cm{sup –2} s{sup –1} in a 12' × 12' field of view. The brightness of the thermal component in this central region does not allow more stringent upper limits on the IC component when compared with non-imaging instruments with much larger fields of view where claims of detections have been made. Future mosaic NuSTAR observations of Coma will further address this issue. The temperature map shows a relatively uniform temperature distribution with a gradient from the hot northwest side to the cooler southeast, in agreement with previous measurements. The temperature determination is robust given the flat effective area and low background in the 3-20 keV band, making NuSTAR an ideal instrument to measure high temperatures in the intracluster medium.

  16. Applying patient centered approach in management of pulmonary tuberculosis: A case report from Malaysia.

    2011-06-01

    A 24 year university student with history of productive cough was registered as sputum smear confirmed case of pulmonary tuberculosis. During treatment, patient suffered from itchiness associated with anti tuberculosis drugs and was treated with chlorpheniramine (4mg) tablet. Patient missed twenty eight doses of anti tuberculosis drugs in continuation phase claiming that he was very busy in his studies and assignments. Upon questioning he further explained that he was quite healthy after five months and unable to concentrate on his studies after taking prescribed medicines. His treatment was stopped based on clinical improvement, although he did not complete six months therapy. Two major reasons; false perception of being completely cured and side effects associated with anti TB drugs might be responsible for non adherence. Non sedative anti histamines like fexofenadine, citrizine or loratidine should be preferred over first generation anti histamines (chlorpheniramine) in patients with such lifestyle. Patient had not completed full course of chemotherapy, which is preliminary requirement for a case to be classified as "cure" and "treatment completed". Moreover, patient had not defaulted for two consecutive months. Therefore, according to WHO treatment outcome categories, this patient can neither be classified as "cure" or "treatment completed" nor as "defaulter". Further elaboration of WHO treatment outcome categories is required for adequate classification of patients with similar characteristics. Likelihood of non adherence can be significantly reduced by applying the WHO recommended "Patient Centered Approach" strategy. Close friend, class mate or family member can be selected as treatment supporter to ensure adherence to treatment.

    2015-02-01

    Full Text Available In this paper, we address the topic of user-centered design (UCD for cartography, GIScience, and visual analytics. Interactive maps are ubiquitous in modern society, yet they often fail to “work” as they could or should. UCD describes the process of ensuring interface success—map-based or otherwise—by gathering input and feedback from target users throughout the design and development of the interface. We contribute to the expanding literature on UCD for interactive maps in two ways. First, we synthesize core concepts on UCD from cartography and related fields, as well as offer new ideas, in order to organize existing frameworks and recommendations regarding the UCD of interactive maps. Second, we report on a case study UCD process for GeoVISTA CrimeViz, an interactive and web-based mapping application supporting visual analytics of criminal activity in space and time. The GeoVISTA CrimeViz concept and interface were improved iteratively by working through a series of user→utility→usability loops in which target users provided input and feedback on needs and designs (user, prompting revisions to the conceptualization and functional requirements of the interface (utility, and ultimately leading to new mockups and prototypes of the interface (usability for additional evaluation by target users (user… and so on. Together, the background review and case study offer guidance for applying UCD to interactive mapping projects, and demonstrate the benefit of including target users throughout design and development.

    Full Text Available Background: Neoplastic meningitis (NM is a condition characterized by leptomeningeal involvement by metastatic carcinoma. Detection of exfoliated malignant cells in cerebrospinal fluid (CSF due to meningeal metastasis is frequently associated with diverse neurologic presentations. Materials and Methods: In this retrospective study of all cases of NM diagnosed in CSF samples over a 20-year period at a tertiary care referral center, the cytomorphologic features were reviewed. Results: Sixty six cases of NM were identified of which 36 already had an established diagnosis of malignancy while in 30 patients, there was no previously known tumor. The most common known primary in the former group was breast followed by ovary. Single cell pattern, cellular cannibalism, moderate cytoplasm and rounded nuclei were seen in breast and lung tumors. Papillary architecture and cytoplasmic vacuolation were seen in the ovarian primaries. Melanin pigment was seen in malignant melanoma. Conclusion: CSF cytology is an important tool for diagnosis of NM. Cytomorphologic features helped in diagnosis and for prediction of the primary site. Correct identification of this condition is important as it has therapeutic and prognostic implications.

    Landsat data have been produced, archived, and distributed by the U.S. Geological Survey (USGS) since 1972. Scientists and users rely on these data for historical study of land surface change, but shoulder the burden of post-production processing to create applications-ready data sets. In compliance with guidelines established through the Global Climate Observing System, USGS has embarked on production of higher-level Landsat data products to support land surface change study. Terrestrial variables such as surface reflectance and land surface temperature will be offered as Climate Data Records (CDR). Derivations of spectral indices from surface reflectance are also produced, to further ease user application in land remote sensing science. Higher level products, such as leaf area index, burned area extent, snow covered area, and surface water extent representing Essential Climate Variables (ECV) will be available soon.

    Complexity theory has been adopted by a number of studies as a benchmark to investigate the performance of socio-technical systems, especially those that are characterized by relevant cognitive work. However, there is little guidance on how to assess, systematically, the extent to which a system is complex. The main objective of this study is to carry out a systematic analysis of a SAMU (Mobile Emergency Medical Service) Medical Regulation Center in Brazil, based on the core characteristics of complex systems presented by previous studies. The assessment was based on direct observations and nine interviews: three of them with regulator of emergencies medical doctor, three with radio operators and three with telephone attendants. The results indicated that, to a great extent, the core characteristics of complexity are magnified) due to basic shortcomings in the design of the work system. Thus, some recommendations are put forward with a view to reducing unnecessary complexity that hinders the performance of the socio-technical system.

    We present radio images within 30$''$ of Sgr A* based on recent VLA observations at 34 GHz with 7.8 microJy sensitivity and resolution $\\sim88\\times46$ milliarcseconds (mas). We report 44 partially resolved compact sources clustered in two regions in the E arm of ionized gas that orbits Sgr A*. These sources have size scales ranging between ~50 and 200 mas (400 to 1600 AUs), and a bow-shock appearance facing the direction of Sgr A*. Unlike the bow-shock sources previously identified in the near-IR but associated with massive stars, these 34 GHz sources do not appear to have near-IR counterparts at 3.8 $\\mu$m. We interpret these sources as a candidate population of photoevaporative protoplanetary disks (proplyds) that are associated with newly formed low mass stars with mass loss rates ~10^{-7} - 10^{-6} solar mass per year and are located at the edge of a molecular cloud outlined by ionized gas. The disks are externally illuminated by strong Lyman continuum radiation from the ~100 OB and WR massive stars dist...

    Eight spontaneous pulmonary tumors (four bronchiolar tubular adenomas, two bronchiolar adenocarcinomas, two squamous-cell carcinomas) occurred in a total of 54 adult tree shrews (Tupaia belangeri) of the GPC colonies between 1978 and 1994. The adenomas and adenocarcinomas consisted of tubularly or trabecularly arranged cuboidal to cylindrical cells interspersed with some PAS-positive goblet cells, thus resembling the epithelial lining of respiratory bronchioles of tree shrews. The two squamous-cell carcinomas probably originated from the pulmonary alveoles. Three more pulmonary tumors (one small-cell carcinoma, one bronchial adenoma, one squamous-cell carcinoma) developed in 409 adult callitrichids of the GPC colonies during the same period, and one more bronchial adenoma was observed in a common marmoset (Callithrix jacchus) of another colony located in Göttingen. With regard to the adenomas and squamous-cell carcinomas, a similar cellular origin with the three shrews is assumed. The small-cell carcinoma possibly developed from the bronchial epithelium, provided a pathogenesis parallel to that of human small-cell carcinoma is suggested. Four of the tree shrew pulmonary adenomas/adenocarcinomas and the small-cell Ca were macroscopically visible as yellowish-grey nodules of 1 mm x 1 mm to 15 mm x 15 mm diameter, predominantly involving the main lobes (2 x right main lobes, 2 x left main lobes, 1 x all lobes). The pulmonary tumors of the other animals were below macroscopical detectability.

    An analysis on 83 cases of posthemiplegic omalgia (shoulder pain) shows that the pathogenesis of the pain is closely related to the improper passive movement at the early stage of hemiplegia (62.7%). The large range of passive movement is a dangerous factor leading to omalgia. In the study of upper extremity complications, the incidence of shoulder-hand syndrome is relatively high (42.2%), and it is often accompanied by hand swelling (83.1%). The authors suggest that painless movement of the shoulder joint should be limited in a range of 90-120 degrees, massage be carried out immediately after acupuncture, and the affected upper extremity be moved passively during the needle retention. This therapeutic method is definitely effective for pasthemiplegic omalgia.

    Mouse fibroblast cell line NIH3T3 cells were labeled with the heavy metal (silver and gold) and observed intracellular structure under an X-ray microscope. Microtubules, Golgi apparatus and early endosomes of NIH3T3 cells were stained with immuno-gold nanoparticles, and immuno-staining was intensified by silver or gold enhancement procedure. Using a transmission soft X-ray microscope beamline (BL12) at Ritsumeikan University SR center, we observed immuno-stained NIH3T3 cells with several wavelengths just below and above oxygen edge ({lambda} = 2.32 nm). Using this method, cytoskeleton (microtubules) and organelles (Golgi apparatus and early endosomes) were successfully imaged with high resolution. Thus, immuno-gold silver and gold enhancement technique is useful for specific labeling of intracellular structure under an X-ray microscope.

    Galaxy observations and N-body cosmological simulations produce conflicting dark matter halo density profiles for galaxy central regions. While simulations suggest a cuspy and universal profile (UDP) of this region, the majority of observations favor variable profiles with a core in the center. In this paper, we investigate the convergency of standard N-body simulations, especially in the cusp region, following the approach proposed by (Baushev, 2015). We simulate the well known Hernquist model using the SPH code Gadget-3 and consider the full array of dynamical parameters of the particles. We find that, although the cuspy profile is stable, all integrals of motion characterizing individual particles suffer strong unphysical variations along the whole halo, revealing an effective interaction between the test bodies. This result casts doubts on the reliability of the velocity distribution function obtained in the simulations. Moreover, we find unphysical Fokker-Planck streams of particles in the cusp region.

    A situation is described of suddenly erupting conflict in an interdisciplinary meeting of psychiatric hospital staff. The conflict is related to the systemic impact of recent changes in psychiatric hospital practice. The observed affect and interpersonal dynamics are reviewed in the context of different conceptual frameworks. These include Maslow's hierarchy of needs model, the group focal conflict paradigm and the concept of scapegoating. The use and integration of these three approaches toward understanding affectively laden administrative conflict are discussed. Specific reference is made to the utilization of such understanding in developing leadership skills in a multi-disciplinary mental health setting.

    Full Text Available Information centers are duly obliged to move in line with their parent organizations’ goals and missions in creating knowledge. In the age of information and communication revolution, and in a knowledge-based economy, organizations that are involved in creation of knowledge have an important role in communication and diffusion of knowledge. In the mean time, libraries and information centers change from being mere depository sources to knowledge institutions. The current research aimed to study the present state of knowledge management infrastructures of the Regional Information Center for Science and Technology (RICeST as a national and regional information center. The statistic population of this study was consisted of 87 staff. Data was collected by means of questionnaires, observation and interviews. The results showed the required infrastructure for KM activities were almost there, among different aspects of which, budgeting had a better situation in the institution under study. In regards with establishment of knowledge management, RICeST was paying more attention to information and communication technology and knowledge network via applications such as the Internet and extranets. Another fact was that in the RICeST, emphasis was on learning and on human resources as the substantial sources in creation of knowledge. Among other aspects, “organizational culture” was in a lower state compared with other aspects in the RICeST.

    1992-10-01

    Degenerative joint disease of the tarsi was diagnosed in 20 of 24 Holstein bulls with tarsal lameness at 2 artificial insemination centers from 1975 to 1987. Each of the 2 centers housed about 100 bulls/yr. Of the 24 bulls with tarsal lameness, 22 were from the artificial insemination center designated as A, and 2 were from the center designated as B. Examination of the housing and management procedures revealed that center A had concrete floors with cuboidal-shaped yards, whereas center B had deep sand flooring, with long, narrow yards. The only other difference between the 2 centers was that center A used 1- and 2-year-old bulls as teasers for older, heavier bulls to mount, whereas center B used bulls that were at least 6 years old to withstand the stress placed on their hind limbs by the weight of bulls undergoing semen collection. Radiographic lesions of tarsi of bulls from both centers ranged from distention of the tibiotarsal joint pouch to hypertrophic degenerative osteoarthritis of the distal, intertarsal, and tarsometatarsal joints. It was concluded that the concrete flooring and the semen collecting practices were responsible for the high prevalence of tarsal lameness and degenerative joint disease of the tarsi in bulls housed at center A.

    As one of the most active volcano in the earth, Mount Merapi is periodically erupted and it is considered as a natural disaster for the surrounding area. Kabupaten Sleman as one of the nearest location to this mount has to be always prepared to this disaster. The local government already set three different groups of region, in which potentially affected by Mount Merapi eruption, called KRB I, KRB II, and KRB III. Region KRB III is the closest area to the mount crater and most often affected by the eruption disaster. Whenever KRB III is affected, people live in that area usually being transfer to the next region set that is KRB II. The case presented in this paper is located at the KRB II region, which is the second closest region to the mount crater. A humanitarian distribution system has to be set in this region, since usually this region is became the location of shelters for KRB III population whenever a ‘big’ eruption is happened. A mathematical model is proposed in this paper, for determining the location of distribution center, vehicle route, and the amount of goods delivered to each customer. Some numerical illustration are presented in order to know the behavior of the proposed model.

    Progressively transformed germinal centers (PTGC), a lymph node process unfamiliar to most otolaryngologists, is a morphological variant of reactive lymphofollicular hyperplasia of lymph nodes. Immunoglobulin (Ig)G4-related disease (IgG4-RD) is a newly identified condition, characterized by hyper-IgG4-γ-globulinemia and mass-forming or hypertrophic lesions associated with infiltration of IgG4(+) plasma cells in the affected organs. Recently, a case study of PTGC was reported that fulfilled the diagnostic criteria of IgG4-RD (IgG4(+) PTGC) [1]. A 68-year-old male was referred to our hospital with swelling in the left submandibular region. Palpation revealed swollen lymph nodes, the largest of which measured 5cm in diameter. (18)F-fluorodeoxyglucose (FDG)-positron emission tomography/computed tomography identified lymphadenopathy with high (18)F-FDG uptake in the left submandibular region. We strongly suspected malignant lymphoma, and excisional biopsy of the submandibular lymph node was performed under general anesthesia. Pathological findings were consistent with IgG4(+) PTGC, and serological examination demonstrated elevated levels of IgG4. These findings were consistent with IgG4-RD. The patient did not have systemic lesions; therefore, he has not undergone corticosteroid therapy. IgG4(+) PTGC should be considered as a differential diagnosis for cervical lymphadenopathy by otolaryngologists as well as pathologists.

    Research service cores at academic health centers are important in driving translational advancements. Specifically, biostatistics and research design units provide services and training in data analytics, biostatistics, and study design. However, the increasing demand and complexity of assigning appropriate personnel to time-sensitive projects strains existing resources, potentially decreasing productivity and increasing costs. Improving processes for project initiation, assigning appropriate personnel, and tracking time-sensitive projects can eliminate bottlenecks and utilize resources more efficiently. In this case study, we describe our application of lean six sigma principles to our biostatistics unit to establish a systematic continual process improvement cycle for intake, allocation, and tracking of research design and data analysis projects. The define, measure, analyze, improve, and control methodology was used to guide the process improvement. Our goal was to assess and improve the efficiency and effectiveness of operations by objectively measuring outcomes, automating processes, and reducing bottlenecks. As a result, we developed a web-based dashboard application to capture, track, categorize, streamline, and automate project flow. Our workflow system resulted in improved transparency, efficiency, and workload allocation. Using the dashboard application, we reduced the average study intake time from 18 to 6 days, a 66.7% reduction over 12 months (January to December 2015).

    The following case study describes an ergonomics intervention program, designed and implemented by an occupational therapist (OT), which included principles of participatory ergonomics, had full support of management and administration, and addressed the work, worker, and environment. The ergonomics program took place in the Sterile Processing Center (SPC) of a 398 bed, mid-western hospital. The SPC was responsible for the collection, sterilization, and reassembling of hospital surgical equipment. The 30 employees of the SPC were vulnerable to injury, having experienced 19 in only two years (of the 19 injuries, 9 were WMSD or ergonomics-related injuries). Over a two and a half year period, the OT and SPC manager conducted ergonomic evaluations, implemented employee training, designed a new SPC department, and modified work processes and equipment. In the year following the training and changes, the SPC staff experienced no injuries. Because of it's success, the program is continuing on a quarterly basis to ensure new problems are addressed quickly, new processes or equipment are evaluated, and new staff are properly trained.

    The characteristics of the post-noon aurora observed at Antarctic Zhongshan station on June 12, 1999, were discussed and analyzed. In the condition of the magnetic activity is not large(Kp≈l), for post-noon 630. 0 nm emissions, the total fluxes of soft precipitating particles were increasing from 10:50 UT to 13:35 UT and were decreasing from 13 :35 UT to 18 :00 UT in almost monotonous way. Away from noon, the 557. 7 nm emissions increased gradually from 10 :50 UT to 17 :10 UT. The behaviors of the precipitat- ing particles for exciting 630. 0 nm aurora and 557. 7 nm aurora were quite different. The peak intensity of 630. 0 nm and 557. 7 nm emissions appeared at about 13:35 UT and 15:40 UT respectively, the time differ- ence of two peaks is about 2 h. The energy of precipitating electrons remained fairly steady until 15:00 UT when it rose dramatically.

    Full Text Available Vertex and p-center problems are two well-known types of the center problem. In this paper, a p-center problem with uncertain demand-weighted distance will be introduced in which the demands are considered as fuzzy random variables (FRVs and the objective of the problem is to minimize the maximum distance between a node and its nearest facility. Then, by introducing new methods, the proposed problem is converted to deterministic integer programming (IP problems where these methods will be obtained through the implementation of the possibility theory and fuzzy random chance-constrained programming (FRCCP. Finally, the proposed methods are applied for locating bicycle stations in the city of Tabriz in Iran as a real case study. The computational results of our study show that these methods can be implemented for the center problem with uncertain frameworks.

    2012-01-01

    Data from the Fermi-LAT reveal two large gamma-ray bubbles, extending 50 degrees above and below the Galactic center, with a width of about 40 degrees in longitude. The gamma-ray emission associated with these bubbles has a significantly harder spectrum (dN/dE E-2) than the IC emission from electrons in the Galactic disk, or the gamma-rays produced by decay of pions from proton-ISM collisions. The bubbles are spatially correlated with the hard-spectrum microwave excess known as the WMAP haze; the edges of the bubbles also line up with features in the ROSAT X-ray maps at 1.5 - 2 keV. We further discovered arge cocoon structures in Fermi gamma-ray data, which is presumably produced by relativistic large scale jets. I will summarize observational evidence of the Fermi bubbles and cocoons, including features of polarization and rotation measure of the bubble edges. The bubbles have sharp edges in gamma-ray, X-ray, and polarized microwave emission. I'm going to argue that these Galactic gamma-ray bubbles are ongoing shocks (instead of a stable structure), and were most likely created by some large episode of energy injection in the Galactic center, such as past accretion events onto the central massive black hole, or a nuclear starburst in the last ˜10 Myr.

  6. Extension of centered hydrodynamical schemes to unstructured deforming conical meshes : the case of circles

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available In a prior work [CEMRACS10], a curvilinear bi-dimensional finite volume extension of Lagrangian centered schemes GLACE [GLACE] on unstructured cells, whose edges are parameterized by rational quadratic Bézier curves was proposed and we showed numerical results for this scheme. Now, we extend the EUCCLHYD scheme [EUCCLHYD] to these cells. To simulate flows with evolving large deformations, we write a formalism allowing the time evolution of the conic parameter. As an example, this allows an edge changing from an ellipse segment to a hyperbolic one. In this framework, we consider the case of a mesh whose edges are circle segments with non fixed centers. We show that this formalism extends also the previous work [GLACE CIRCLE] (which is equivalent to [CEMRACS10] when conic edges are all circles. This is a necessary first step toward general conical deformation. Dans un travail précédent [CEMRACS10], une extension volume fini bi-dimensionnelle curviligne du schéma Lagrangien centré GLACE [GLACE] sur des cellules non structurées dont les bords sont paramétrés par des courbes de Bézier quadratiques rationnelles a été proposée. Maintenant, nous proposons une extension du schéma EUCCLHYD [EUCCLHYD] à ce type de cellules et pour lequel nous montrons quelques résultats numériques. Pour pouvoir suivre un écoulement subissant de grandes variations de forme, nous écrivons un formalisme qui permet l’évolution en temps du paramètre de chaque conique. Ainsi, un bord de maille peut d’un segment d’ellipse devenir en cours de calcul un segment d’hyperbole. Dans ce cadre, nous considérons le cas particulier d’un maillage dont les bords de cellules sont des arcs de cercle avec des centres non fixes. Nous montrons que ce formalisme constitue également une extension directe d’un travail précédent [GLACE CIRCLE] (qui équivaut à [CEMRACS10] dans le cas où les bords coniques sont tous des cercles.

    Hesham A. Baraka

    2015-03-01

    The objective of this paper was to introduce a new technique that can support decision makers in the call centers industry to evaluate, and analyze the performance of call centers. The technique presented is derived from the research done on measuring the success or failure of information systems. Two models are mainly adopted namely: the Delone and Mclean model first introduced in 1992 and the Design Reality Gap model introduced by Heeks in 2002. Two indices are defined to calculate the performance of the call center; the success index and the Gap Index. An evaluation tool has been developed to allow call centers managers to evaluate the performance of their call centers in a systematic analytical approach; the tool was applied on 4 call centers from different areas, simple applications such as food ordering, marketing, and sales, technical support systems, to more real time services such as the example of emergency control systems. Results showed the importance of using information systems models to evaluate complex systems as call centers. The models used allow identifying the dimensions for the call centers that are facing challenges, together with an identification of the individual indicators in these dimensions that are causing the poor performance of the call center.

    Utilizing electronic data capture (EDC) systems in data collection and management allows automated validation programs to preemptively identify and correct data errors. For our multi-center, prospective study we chose to use TeleForm, a paper-based data capture software that uses recognition technology to create case report forms (CRFs) with similar functionality to EDC, including custom scripts to identify entry errors. We quantified the accuracy of the optimized system through a data audit of CRFs and the study database, examining selected critical variables for all subjects in the study, as well as an audit of all variables for 25 randomly selected subjects. Overall we found 6.7 errors per 10,000 fields, with similar estimates for critical (6.9/10,000) and non-critical (6.5/10,000) variables – values that fall below the acceptable quality threshold of 50 errors per 10,000 established by the Society for Clinical Data Management. However, error rates were found to widely vary by type of data field, with the highest rate observed with open text fields. PMID:24709056

    The purpose of this retrospective study was to investigate treatment options for orbital floor fractures at a Level 1 Trauma Center in Southern California. A review of 45 cases of isolated orbital floor fractures treated at the University of California at Irvine between February 2004 and April 2007 was done. Patients were retrospectively analyzed for gender, age, mechanism of injury, associated facial injuries, presenting symptoms, method of treatment, and postoperative complications. Thirty-six male patients and nine female patients were treated. Motor vehicle collision (26/45) was the most common cause of injury, and the mean age of the patients was 35.5 years (range: 15-81 years). Ecchymosis surrounding the orbital tissue was the most common presentation (38/45). Diplopia was present in 8 of 45 patients, with 1 patient requiring urgent decompression for retrobulbar hematoma. Forty-three patients underwent surgical repair; 40 underwent transconjunctival approach with lateral canthotomy; 17 underwent reconstruction with porous polyethylene Medpor (Porex Surgical, Inc., College Park, GA.); and 26 underwent reconstruction with a titanium mesh plate. Immediate postoperative complications included 12 patients with infraorbital numbness, 3 with diplopia, 1 with cellulitis, and 1 with ectropion with a subcilliary approach. Average timing of surgery of our study was 4.94 days (range, 1-20 days). Orbital floor fracture management has changed significantly over the past few decades with the introduction of new internal fixation methods and new materials for reconstructing orbital floor defects. Recommendations for surgical intervention on orbital floor fractures mostly depend on clinical examination and imaging studies. Consequences of inadequate repair of orbital floor fractures can lead to significant facial asymmetry and visual problems. Both porous polyethylene and titanium plates are effective tools for reconstructing the orbital floor. Our review demonstrates that

    2014-06-01

    Full Text Available This paper examined customers’ perceived importance and performance of shopping center ambience on the examples of the Mercator shopping center and Sad Novi Bazaar shopping center in Novi Sad, Serbia. The shopping center ambience was examined through exterior and interior attributes. It was found that a number of them are very important to customers and their shopping behavior. According to the present research, the most important exterior attributes are: address and location, parking availability, congestion and traffic, exterior display windows and entrances. The most important interior attributes are: cleanliness, temperature, merchandise, lighting, music, scents, absence of tobacco smoke, width of aisles and P.A. usage. The paper also provided information for two studied shopping centers with ambience attributes that performed well or not and everything was presented on the importance-performance grids, which can serve managers as guidelines for further development.

    Background:Although primary hypophysitis is not uncommon,a granulomatous etiology of hypophysitis is relatively rare.Radiological and diagnostic characteristics of several isolated cases have been described to date.However,to the best of our knowledge,surgical treatment of eight cases of granulomatous hypophysitis confirmed by histopathology has not yet been reported.Methods:A retrospective study was performed to review cases of granulomatous hypophysitis from November 2003 to November 2013 in our neurosurgical department.Only eight out of 1345 operations were diagnosed with granulomatous hypophysitis.Results:The cohort included two men and six women.The most common manifestations reported were headache,fatigue and polyuria.All six female patients presented with either menstrual disorders or amenorrhea.Seven of eight patients suffered polyuria.Two patients suffered bitemporal hemianopsia.One was accompanied with eosinophilic granuloma of the skull.Prolactin levels were increased in six patients,four of them were noted to have thyroid axis imbalances,one was noted to be deficient in the gonadotropin axis and two were deficient in the adrenal axis.The lesion demonstrated homogenous enhancement and an abnormally thickened pituitary stalk.A histological diagnosis of granulomatous hypophysitis was established in all eight patients,who were treated surgically.Characteristic granulomas formed by epithelioid histiocytes and multinucleated giant cells were observed.Conclusions:Pure glucocorticoid therapy is less effective than surgical intervention and has not been recommended for the treatment of granulomatous hypophysitis.Although replacement therapy can relieve associated symptoms,we conclude surgical intervention,particularly minimally invasive surgery via a transsphenoidal approach,to be mandatory in establishing a diagnosis and reducing the size of the inflammatory mass.Adjuvant corticosteroids therapy is recommended.

  14. Thirty Years of Data Management for Earth Observations at the National Snow and Ice Data Center (NSIDC)

    Over the past 30 years the National Snow and Ice Data Center (NSIDC) has managed data in a way that directly or indirectly supports earth observations. NSIDC's Distributed Active Archive Center (DAAC) supports the cryospheric missions of the NASA Earth Observing System's satellites. The new Cooperative Data and Information System (CADIS), joint with NCAR and UCAR, supports the (largely) NSF funded Arctic Observing Network (AON). Indirectly, NSIDC supports the Global Climate Observing System and other Earth monitoring efforts by archiving data that contribute to their missions. Some simple truths about observing systems emerge from our long history of storing and serving their data. They include: New instruments have to be "backward compatible" with old. A few long, continuous, records are at least as valuable as numerous sporadic new short records from a number of PIs or satellite programs, even if the short records are more precise. International collaborations are essential for building networks and for establishing data sharing protocols. Examples of currently active NSIDC affiliations include International Polar Year Data Coordination Service of ICSU (International Council for Science), the International Permafrost Association, the World Glacier Monitoring Service, and the Joint WMO-IOC Commission for Oceanography and Maritime Meteorology (JCOMM) for the Global Sea Ice Data Bank. While some observations are useful on their own (like sea ice or snow extent) many are only informative when combined with other like or contrasting observations in some way. It is difficult to get funding for developing higher level or integrative products like atlases, climatologies, near-real-time data streams, or even data on the same grid or in the same format, but these are some of NSIDC's most used data sets. They include the first global assembly of data and information on frozen ground (CAPS), Environmental Atlases for arctic meteorology, oceanography, and sea ice; and passive

    The Fermi Large Area Telescope (LAT) has opened the way for comparative studies of cosmic rays (CRs) and high-energy objects in the Milky Way (MW) and in other, external, star-forming galaxies. Using 2 yr of observations with the Fermi LAT, Local Group galaxy M31 was detected as a marginally extended gamma-ray source, while only an upper limit has been derived for the other nearby galaxy M33. We revisited the gamma-ray emission in the direction of M31 and M33 using more than 7 yr of LAT Pass 8 data in the energy range 0.1{--}100 {GeV}, presenting detailed morphological and spectral analyses. M33 remains undetected, and we computed an upper limit of 2.0× {10}-12 {erg} {{cm}}-2 {{{s}}}-1 on the 0.1{--}100 {GeV} energy flux (95% confidence level). This revised upper limit remains consistent with the observed correlation between gamma-ray luminosity and star formation rate tracers and implies an average CR density in M33 that is at most half of that of the MW. M31 is detected with a significance of nearly 10σ . Its spectrum is consistent with a power law with photon index {{Γ }}=2.4+/- {0.1}{stat+{syst}} and a 0.1{--}100 {GeV} energy flux of (5.6+/- {0.6}{stat+{syst}})× {10}-12 {erg} {{cm}}-2 {{{s}}}-1. M31 is detected to be extended with a 4σ significance. The spatial distribution of the emission is consistent with a uniform-brightness disk with a radius of 0.°4 and no offset from the center of the galaxy, but nonuniform intensity distributions cannot be excluded. The flux from M31 appears confined to the inner regions of the galaxy and does not fill the disk of the galaxy or extend far from it. The gamma-ray signal is not correlated with regions rich in gas or star formation activity, which suggests that the emission is not interstellar in origin, unless the energetic particles radiating in gamma rays do not originate in recent star formation. Alternative and nonexclusive interpretations are that the emission results from a population of millisecond pulsars

    Skin color is important to people in many societies. In this descriptive cross-sectional study, the causes of skin disorders in patients presenting for consultation over a period of 5 years were assessed and identified. A total of 4,510 dyschromia cases were recorded, representing 9% of the total number of patients attending for consultations at the Dermatology Center of Abidjan over this period. Pigmentation disorders were more often found in female patients (53.56%; sex ratio female:male=1.44) and were predominant in patients 20--30 years old (50%). All socio-professional categories were represented. However, students and service professionals (hairdressers, dressmakers, traders and switchboard operators) represented 50% of the patients with pigmentation disorders. Hyperchromia was common (48.49%) and was found in exposed areas of the skin. Most of the pigmentation disorders (60.94%) were of post-inflammation origin. Vitiligo was the most frequent etiology of systemic or endocrine dyschromia (92.63%). Among the hereditary pigmentation disorders, pigmented naevus was the most commonly found (41.5%). Dyschromic chemical eruptions appeared most frequently in the form of fixed pigmented erythema (84.55%). This study demonstrates that pigmentation disorders are still a frequent reason for consultation due to their distressing consequences.

    The XMM-Newton observatory is a cornerstone mission of the European Space Agency (ESA) Horizon 2000 program. This spacecraft, the largest ever flown by ESA for a scientific program, was launched on December 10, 1999, carrying a payload funded by ESA member states and the USA (NASA). The scientific payload comprises three CCD imaging cameras (European Photon Imaging Cameras, EPIC), sensitive in the 0.1-15 keV band, and two Reflecting Grating Spectrometers (RGS), sensitive in the 0.3-2.1 keV band, and characterized by a resolving power E/ΔE = 100 to 800. The X-ray instruments are complemented by an Optical Monitor, sensitive in the 150-650nm band, which allows simultaneous multiwavelength monitoring of celestial sources. The XMM-Newton observational program is determined on the bases of the proposals sent in response to Announcement of Opportunities, and selected by peer review panels. The XMM-Newton Science Archive (XSA) contains all the science data of all the performed observations. Its user interface (http:xmm.vilspa.esa.es/xsa) allows a user to retrieve them after the 1-year proprietary period has expired. Calibration observations are normally not covered by proprietary rights; their data being therefore public. Target of Opportunity and Discretionary Time observations have a 6-months proprietary period. For each archived observation, the XSA stores Observation Data Files (ODF) and Pipeline Processing System (PPS) products, if available, as well as the XMM-Newton EPIC serendipitous catalogue, the OM source catalogue and the Slew Survey Source Catalogue (see the catalogues documentation at http://xmm.esac.esa.int/xsa). The ODF comprises raw telemetry files, reformatted in FITS format, and contains uncalibrated information. The PPS products are a collection of top-level, validated scientific and cross-correlation products, routinely generated by the Science Survey Center, University of Leicester, UK (http://xmmssc-www.star.le.ac.uk).

    AIM: To identify the clinical features and outcomes of infrequently reported leptomeningeal carcinomatosis (LMC) of gastric cancer.METHODS: We analyzed 54 cases of cytologically con- firmed gastric LMC at four institutions from 1994 to 2007.RESULTS: The male-to-female ratio was 32:22, and the patients ranged in age from 28 to 78 years (median,48.5 years). The majority of patients had advanced disease at initial diagnosis of gastric cancer. The clinical or pathologic tumor, node and metastasis stage of the primary gastric cancer was Ⅳ in 38 patients (70%).The median interval from diagnosis of the primary malignancy to the diagnosis of LMC was 6.3 mo, ranging between 0 and 73.1 mo. Of the initial endoscopic findings for the 45 available patients, 23 (51%) of the patients were Bormann type Ⅲ and 15 (33%) patients were Bormann type Ⅳ. Pathologically, 94% of cases proved to be poorly differentiated adenocarcinomas.Signet ring cell component was also observed in 40% of patients. Headache (85%) and nausea/vomiting (58%) were the most common presenting symptoms of LMC. A gadolinium-enhanced magnetic resonance imaging was conducted in 51 patients. Leptomeningeal enhancement was noted in 45 cases (82%). Intrathecal (IT) chemotherapy was administered to 36 patientsprimarily methotrexate alone (61%), but also in combination with hydrocortisone/± Ara-C (39%). The median number of IT treatments was 7 (range, 1-18). Concomitant radiotherapy was administered to 18 patients,and concomitant chemotherapy to seven patients. Seventeen patients (46%) achieved cytological negative conversion. Median overall survival duration from the diagnosis of LMC was 6.7 wk (95% CI: 4.3-9.1 wk). In the univariate analysis of survival duration, hemoglobin,IT chemotherapy, and cytological negative conversion showed superior survival duration ( P = 0.038, P = 0.010, and P = 0.002, respectively). However, in our multivariate analysis, only cytological negative conversion was predictive of

    Full Text Available Aim: To investigate endocrinologic and endometrial factors in cases of recurrent abortions. Material and Method: In cases of recurrent abortions, clinical and ultrasonographic features, genetic, anatomic and immunologic factors, hormonal profiles and endometrial samplings were assessed. Chromosomal abnormalities and uterine anomalies were excluded. Results: In 8 (14% of 57 cases with recurrent abortions, there were low progesterone levels. In 1 (1.75% case there was a high androgen level. In 2 (3.5% cases there was hyperprolactinemia and in another 2 (3.5% cases there were high insulin levels. In 4 (7% cases two scores of OGTT were high. In 51 cases where endometrial sampling was performed, only one (1.75% case had delayed endometrial development. Discussion: We conclude that recurrent abortions have a complex etiology related to endocrinologic and endometrial factors.

    Sjouwerman, L O

    2008-01-01

    We present Very Large Array (VLA) radio interferometry observations of the 1720 MHz OH masers in the Galactic Center (GC). Most 1720 MHz OH masers arise in regions where the supernova remnant Sgr A East is interacting with the interstellar medium. The majority of the newly found 1720 MHz OH masers are located to the northeast, independently indicating and confirming an area of shock interaction with the +50 km/s molecular cloud (M-0.02-0.07) on the far side of Sgr A East. The previously known bright masers in the southeast are suggested to be the result of the interaction between two supernova remnants, instead of between Sgr A East and the surrounding molecular clouds as generally found elsewhere in the Galaxy. Together with masers north of the circumnuclear disk (CND) they outline an interaction on the near side of Sgr A East. In contrast to the interaction between the +50 km/s cloud and Sgr A East, OH absorption data do not support a direct interaction between the CND material and Sgr A East. We also prese...

    2016-10-05

    Zika virus (ZIKV) and chikungunya virus (CHIKV) cocirculate throughout much of the tropical Western Hemisphere; however, few cases of coinfection with these two pathogens have been reported. Herein, we describe three cases of ZIKV-CHIKV coinfection detected at a single center in Ecuador: a patient who developed symptoms on postoperative day 5 from an orthopedic procedure, a woman who had traveled to Ecuador for fertility treatment, and a woman who was admitted for Guillain-Barré syndrome and had ZIKV and CHIKV detected in serum and cerebrospinal fluid. All cases were diagnosed using a multiplex real-time reverse transcription polymerase chain reaction, and ZIKV viremia was detected as late as 16 days after symptom onset. These cases demonstrate the varied clinical presentation of ZIKV-CHIKV coinfections as well as the importance of multiplexed arboviral testing for these pathogens.

  5. Being a case manager for persons with borderline personality disorder: perspectives of community mental health center clinicians.

    Nehls, N

    2000-02-01

    The scope of case management has expanded to include persons with chronic, nonpsychotic disorders, in particular, persons diagnosed with borderline personality disorder. Despite more widespread use, literature about case management for persons with this disorder is limited. To address this gap in knowledge, a study of the day-to-day experiences of case managers who care for persons with borderline personality disorder was conducted. Seventeen community mental health center case managers gave their informed consent to participate in individual, in-depth interviews. The interviews were analyzed using an interpretive phenomenological research approach. The analysis showed a pattern of monitoring self-involvement. The case managers monitored themselves in terms of expressing concern and setting boundaries. These shared practices highlight a central and unique component of being a case manager for persons with borderline personality disorder, that is, the case manager's focus of attention is on self. By focusing on the self, case managers seek to retain control of the nature of the relationship. The author asserts that the matter to be resolved is not to determine whether retaining or relinquishing control is better, but rather, how best to help practitioners maintain a helpful relationship over time with persons who have borderline personality disorder. In an effort to accomplish this goal, questions about current helping practices and suggestions for working collaboratively with persons who have this diagnosis are provided.

    Full Text Available Lately, Internet constitutes a major tool for transactions in every aspect and supports innovative marketing policies. Broadband Internet has become “the key to success” for businesses, as it offers various advantages and benefits through Internet marketing (e-marketing policies. In Greece, mountainous areas are usually covered with snow during winter months; so, skiing centers have become an important asset for winter tourism. The Internet evolution and the development of network infrastructure enhance marketing policies for winter tourism activities. This paper studies the use of marketing policies in Greek skiing centers through the Internet, such as promotional activities, website interactivity, accommodation & entertainment information, online weather forecast, guest book, etc Therefore, the paper aims to optimize and evaluate skiing centers in Greece, qualitatively and quantitatively according to e-marketing policies used as criteria, based on the multicriteria method of PROMETHEE II and further to classify them in groups. Finally we identify and describe the optimum group of skiing centers to be used as a model with enhanced customer communication services.

  14. Technology Transfer Challenges: A Case Study of User-Centered Design in NASA's Systems Engineering Culture

    The Upper Stage (US) section of the National Aeronautics and Space Administration's (NASA) Ares I rocket will require internal access platforms for maintenance tasks performed by humans inside the vehicle. Tasks will occur during expensive critical path operations at Kennedy Space Center (KSC) including vehicle stacking and launch preparation activities. Platforms must be translated through a small human access hatch, installed in an enclosed worksite environment, support the weight of ground operators and be removed before flight - and their design must minimize additional vehicle mass at attachment points. This paper describes the application of a user-centered conceptual design process and the unique challenges encountered within NASA's systems engineering culture focused on requirements and "heritage hardware". The NASA design team at Marshall Space Flight Center (MSFC) initiated the user-centered design process by studying heritage internal access kits and proposing new design concepts during brainstorming sessions. Simultaneously, they partnered with the Technology Transfer/Innovative Partnerships Program to research inflatable structures and dynamic scaffolding solutions that could enable ground operator access. While this creative, technology-oriented exploration was encouraged by upper management, some design stakeholders consistently opposed ideas utilizing novel, untested equipment. Subsequent collaboration with an engineering consulting firm improved the technical credibility of several options, however, there was continued resistance from team members focused on meeting system requirements with pre-certified hardware. After a six-month idea-generating phase, an intensive six-week effort produced viable design concepts that justified additional vehicle mass while optimizing the human factors of platform installation and use. Although these selected final concepts closely resemble heritage internal access platforms, challenges from the application of the

    Tumescence at the Three Sisters volcanic center began sometime between summer 1996 and summer 1998 and was discovered in April 2001 using interferometric synthetic aperture radar (InSAR). Swelling is centered about 5 km west of the summit of South Sister, a composite basaltic-andesite to rhyolite volcano that last erupted between 2200 and 2000 yr ago, and it affects an area ∼20 km in diameter within the Three Sisters Wilderness. Yearly InSAR observations show that the average maximum displacement rate was 3–5 cm/yr through summer 2001, and the velocity of a continuous GPS station within the deforming area was essentially constant from June 2001 to June 2004. The background level of seismic activity has been low, suggesting that temperatures in the source region are high enough or the strain rate has been low enough to favor plastic deformation over brittle failure. A swarm of about 300 small earthquakes (Mmax = 1.9) in the northeast quadrant of the deforming area on March 23–26, 2004, was the first notable seismicity in the area for at least two decades. The U.S. Geological Survey (USGS) established tilt-leveling and EDM networks at South Sister in 1985–1986, resurveyed them in 2001, the latter with GPS, and extended them to cover more of the deforming area. The 2001 tilt-leveling results are consistent with the inference drawn from InSAR that the current deformation episode did not start before 1996, i.e., the amount of deformation during 1995–2001 from InSAR fully accounts for the net tilt at South Sister during 1985–2001 from tilt-leveling. Subsequent InSAR, GPS, and leveling observations constrain the source location, geometry, and inflation rate as a function of time. A best-fit source model derived from simultaneous inversion of all three datasets is a dipping sill located 6.5 ± 2.5 km below the surface with a volume increase of 5.0 × 106 ± 1.5 × 106m3/yr (95% confidence limits). The most likely cause of tumescence is a pulse of

  16. ALMA Observations of the Galactic Center: SiO Outflows and High Mass Star Formation Near Sgr A

    2013-01-01

    Using ALMA observations of the Galactic center with a spatial resolution of 2.61" x 0.97 ", we detected 11 SiO (5-4) clumps of molecular gas in the within 0.6pc (15") of Sgr A*, interior of the 2-pc circumnuclear molecular ring. Three SiO (5-4) clumps closest to Sgr A* show the largest central velocities of approximately 150 kilometers per second and broadest asymmetric linewidths with total linewidths FWZI approximately 110-147 kilometers per second. Other clumps are distributed mainly to the NE of the ionized minispiral with narrow linewidths of FWHM approximately 11-27 kilometers per second. Using CARMA data, LVG modeling of the broad velocity clumps, the SiO (5-4) and (2-1) line ratios constrain the column density N(SiO) approximately 10(exp 14) per square centimeter, and the H2 gas density n(sub H2) = (3-9) x 10(exp 5) per cubic centimeter for an assumed kinetic temperature 100-200K. The SiO (5-4) clumps with broad and narrow linewidths are interpreted as highly embedded protostellar outflows, signifying an early stage of massive star formation near Sgr A* in the last 104 years. Additional support for the presence of YSO outflows is that the luminosities and velocity widths lie in the range detected from protostellar outflows in star forming regions in the Galaxy. Furthermore, SED modeling of stellar sources along the N arm show two YSO candidates near SiO clumps supporting in-situ star formation near Sgr A*. We discuss the nature of star formation where the gravitational potential of the black hole dominates. In particular, we suggest that external radiative pressure exerted on self-shielded molecular clouds enhance the gas density, before the gas cloud become gravitationally unstable near Sgr A*.

    Under Power Development Plan 2015, Thailand has to diversify its heavily gas-fired electricity generation. The main owner of electricity transmission grids is responsible to implement several coal-fired power plants with clean coal technology. To environmentally handle and economically transport unprecedented quantities of sub-bituminous and bituminous coal, a coal center is required. The location of such facility is an important strategic decision and a paramount to the success of the energy plan. As site selection involves many criteria, Fuzzy Analytical Hierarchy Process or Fuzzy-AHP is applied to select the most suitable location among three candidates. Having analyzed relevant criteria and the potential alternatives, the result reveals that engineering and socioeconomic are important criteria and Map Ta Phut is the most suitable site for the coal center.

    2008-09-01

    The organizational structures of academic health centers (AHCs) vary widely, but they all exist along a continuum of integration--that is, the degree to which the academic and clinical missions operate under a single administrative and governance structure. This author provides a brief overview of the topic of AHC integration, including the pros and cons of more integrated or less integrated models. He then traces the evolution of the University of Florida (UF) Health Science Center, which was created in the 1950s as a fully integrated AHC and which now operates under a more distributed management and governance model. Starting as a completely integrated AHC, UF's Health Science Center reached a time of maximal nonintegration (or dys-integration) in the late 1990s and at the beginning of this decade. Circumstances are now pushing the expanding clinical and academic enterprises to be more together as they face the challenges of market competition, federal research budget constraints, and reengineering clinical operations to reduce costs, enhance access, and improve quality and patient safety. Although formal organizational integration may not be possible or appropriate for any number of legal or political reasons, the author suggests that AHCs should strive for "functional integration" to be successful in the current turbulent environment.

    The academic health center information environment is saturated with information of varying quality and overwhelming quantity. The most significant challenge is transforming data and information into knowledge. The University of Cincinnati Medical Center's (UCMC) focus is to develop an information architecture comprising data structures, Web services, and user interfaces that enable individuals to manage the information overload so that they can create new knowledge. UCMC has accomplished much of what is reported in this article with the help of a four-year Integrated Advanced Information Management Systems (IAIMS) operation grant awarded by the National Library of Medicine in 2003. In the UCMC vision for knowledge management, individuals have reliable, secure access to information that is filtered, organized, and highly relevant for specific tasks and personal needs. Current applications and tool sets will evolve to become the next generation knowledge management applications or smart digital services. When smart digital services are implemented, silo applications will disappear. A major focus of UCMC's IAIMS grant is research administration. Testing and building out existing and new research administration applications and digital services is underway. The authors review UCMC's progress and results in developing a software architecture, tools, and services for research administration. Included are sections on the evolution to full integration, the impact of the work at UCMC to date, lessons learned during this research and development process, and future plans and needs.

    2015-01-01

    The origin of irradiation and fluorescence of the 6.4 keV bright giant molecular clouds surrounding Sgr A*, the central supermassive black hole of our Galaxy, remains enigmatic. Testing the theory of a past active period of Sgr A* requires X-ray polarimetry. In this paper, we show how modern imaging polarimeters could revolutionize our understanding of the Galactic Center. Through Monte Carlo modeling, we produce a 4-8 keV polarization map of the Galactic Center, focusing on the polarimetric signature produced by Sgr B1, Sgr B2, G0.11-0.11, Bridge E, Bridge D, Bridge B2, MC2, MC1, Sgr C3, Sgr C2, and Sgr C1. We estimate the resulting polarization, include polarized flux dilution by the diffuse plasma emission detected toward the GC, and simulate the polarization map that modern polarimetric detectors would obtain assuming the performances of a mission prototype. The eleven reflection nebulae investigated in this paper present a variety of polarization signatures, ranging from nearly unpolarized to highly pola...

    Case series Patients: Female, 10 • Female, 15 Final Diagnosis: Secondary hemophagocytic lymphohistiocytosis Symptoms: Arthralgia • CNS manifestations • fever • pancytopenia • rash Medication: — Clinical Procedure: — Specialty: Hematology Objective: Rare co-existence of disease or pathology Background: Hemophagocytic lymphohistiocytosis (HLH) in the background of systemic lupus erythematosus (SLE) is rare. Inability to discriminate between these two entities may be fatal for the patient. Here we report two cases of SLE with secondary HLH, one of which manifested HLH as the initial presentation, and the significance of HLH’s timely diagnosis. Case Report: We describe two cases of SLE secondarily affected by HLH, which were diagnosed by various laboratory parameters and detection of profoundly reduced NK cell activity by using flow cytometry. Both our cases on investigation showed hyperferritinemia, hypertriglyceridemia, hypofibrinogenemia, and marked reduction or complete absence of NK cell activity. Conclusions: Association of secondary HLH with SLE is rare, and when it occurs, differentiating it from lupus flare requires a high degree of suspicion and awareness of this association. Both have overlapping clinical features, but HLH is characterized by hyperferritinemia, hypofibrinogenemia, hypertriglyceridemia, and a decrease in erythrocyte sedimentation rate (ESR) and NK cell activity unlike SLE. Therefore, early diagnosis of HLH in the background of SLE facilitates timely selection of an appropriate treatment modality to prevent fatal complications. PMID:27733745

    Full Text Available Introduction & Background: Benign lesions are very common in breast. The most important consideration for physicians is to differentiate benign processes from malignant ones .Hence the clinicians and radi-ologists both wish to differentiate them even before surgical procedures. The Iranian Center for Breast Cancer linked to Jahad Daneshgahi Center is a referral place for patients with breast complaints. Patients & Methods: Retrospective study of sonographic findings of 111 patients with benign patho-logic diagnosis revealed 72.1% accuracy for sonogra-phy in diagnosing benign masses. In 31 cases (27.9%, the sonographic diagnosis was incorrect. Among the different benign lesions, the most common lesions were cysts, fibradenomas, and fibrocystic changes with respective sonographic accuracy of 100%, 90%, and 62.5%. Results: It shows that sonography has a high sensitiv-ity for diagnosis of benign breast lesions and this sen-sitivity is higher in cysts and fibradenomas which are the most common benign pathologies of breast. Conclusion: As a result, in this center sonography is an imaging modality for evaluating benign breast le-sion especially in young patients with dense breasts and palpable masses. Its unique role in diagnosis of the cysts is valuable especially to avoid repeated biopsies.

    BACKGROUND Hemophagocytic lymphohistiocytosis (HLH) in the background of systemic lupus erythematosus (SLE) is rare. Inability to discriminate between these two entities may be fatal for the patient. Here we report two cases of SLE with secondary HLH, one of which manifested HLH as the initial presentation, and the significance of HLH's timely diagnosis. CASE REPORT We describe two cases of SLE secondarily affected by HLH, which were diagnosed by various laboratory parameters and detection of profoundly reduced NK cell activity by using flow cytometry. Both our cases on investigation showed hyperferritinemia, hypertriglyceridemia, hypofibrinogenemia, and marked reduction or complete absence of NK cell activity. CONCLUSIONS Association of secondary HLH with SLE is rare, and when it occurs, differentiating it from lupus flare requires a high degree of suspicion and awareness of this association. Both have overlapping clinical features, but HLH is characterized by hyperferritinemia, hypofibrinogenemia, hypertriglyceridemia, and a decrease in erythrocyte sedimentation rate (ESR) and NK cell activity unlike SLE. Therefore, early diagnosis of HLH in the background of SLE facilitates timely selection of an appropriate treatment modality to prevent fatal complications.

    Full Text Available Introduction. At the Department of Minimally Invasive Upper Digestive Surgery of the Hospital for Digestive Surgery in Belgrade, hybrid minimally invasive esophagectomy (hMIE has been a standard of care for patients with resectable esophageal cancer since 2009. As a next and final step in the change management, from January 2015 we utilized total minimally invasive esophagectomy (tMIE as a standard of care. Objective. The aim of the study was to report initial experiences in hMIE (laparoscopic approach for cancer and analyze surgical technique, major morbidity and 30-day mortality. Methods. A retrospective cohort study included 44 patients who underwent elective hMIE for esophageal cancer at the Department for Minimally Invasive Upper Digestive Surgery, Hospital for Digestive Surgery, Clinical Center of Serbia in Belgrade from April 2009 to December 2014. Results. There were 16 (36% middle thoracic esophagus tumors and 28 (64% tumors of distal thoracic esophagus. Mean duration of the operation was 319 minutes (approximately five hours and 20 minutes. The average blood loss was 173.6 ml. A total of 12 (27% of patients had postoperative complications and mean intensive care unit stay was 2.8 days. Mean hospital stay after surgery was 16 days. The average number of harvested lymph nodes during surgery was 31.9. The overall 30-day mortality rate within 30 days after surgery was 2%. Conclusion. As long as MIE is an oncological equivalent to open esophagectomy (OE, better relation between cost savings and potentially increased effectiveness will make MIE the preferred approach in high-volume esophageal centers that are experienced in minimally invasive procedures.

    Full Text Available Abstract   Distribution of goods and services in cities is of utmost importance. Selecting appropriate venues for different service centers in a city not only enables the citizens to access these services much more easily, but also reduces the traffic load caused by trips made to reach them. Unfortunately, the lack of a correct urban planning has led to inappropriate formation of many cities around the world in terms of the locations assumed for different service centers. Since the private sector has been given the responsibility to construct most of these centers, changing their current locations may be restricted due to legal obligations. Therefore, it seems necessary for the government to construct new service centers with high competitive facilities to attract customers and to compete with those built by the private sector. In this paper, the selection of appropriate locations to construct new service centers has been studied. Such locations have been selected in a way to fulfill goals such as rapid and easy accessibility for the customers and reduction of traffic drawbacks caused by the related trips. In this regard, a model for service centers with restricted capacity has been designed and a parallel simulated annealing algorithm has been proposed to solve it. Finally, the proposed algorithm has been utilized to locate the health centers around the city of Isfahan and its efficiency has been investigated. The findings highlight the accuracy and speed of the proposed algorithm in location of the health centers of Isfahan.

    We developed a computerised test to evaluate unilateral spatial neglect (USN) using a touchscreen display, and estimated the spatial and temporal patterns of visual search in USN patients. The results between a viewer-centered USN patient and a stimulus-centered USN patient were compared. Two right-brain-damaged patients with USN, a patient without USN, and 16 healthy subjects performed a simple cancellation test, the circle test, a visuomotor search test, and a visual search test. According to the results of the circle test, one USN patient had stimulus-centered neglect and a one had viewer-centered neglect. The spatial and temporal patterns of these two USN patients were compared. The spatial and temporal patterns of cancellation were different in the stimulus-centered USN patient and the viewer-centered USN patient. The viewer-centered USN patient completed the simple cancellation task, but paused when transferring from the right side to the left side of the display. Unexpectedly, this patient did not exhibit rightward attention bias on the visuomotor and visual search tests, but the stimulus-centered USN patient did. The computer-based assessment system provided information on the dynamic visual search strategy of patients with USN. The spatial and temporal pattern of cancellation and visual search were different across the two patients with different subtypes of neglect.

    Full Text Available Abstract Introduction Nasopharyngeal cancer commonly manifests with cervical lymphadenopathy, recurrent epistaxis and progressive nasal obstruction. Neuro-ophthalmic and otologic manifestations can also occur. Isolated otologic presentations of nasopharyngeal cancer are rare and the diagnosis of nasopharyngeal cancer may not be foremost in the list of differentials. Case presentation We present the case of a 29-year-old Nigerian woman with bilateral conductive hearing loss and tinnitus after air travel. There were no other symptoms. The persistence of the symptoms after adequate treatment for otitic barotrauma necessitated re-evaluation, which led to a diagnosis of nasopharyngeal cancer. Conclusion Isolated otologic manifestations of nasopharyngeal cancer are rare in regions with low incidence of the disease. There is a need for it to be considered as a possible differential in patients presenting with bilateral serous otitis media.

    Full Text Available Structural and qualitative evaluation of Revised National Tuberculosis Control Programme (RNTCP is important to determine actual status of the programme in the field settings and to uncover the concealed gaps. The present cross-sectional study assessed the infrastructural facilities and quality of services provided through microscopy and directly observed treatment (DOT centers at Nanded city of Maharashtra. The investigator made on spot observation on the activities at microscopy and DOT centers and assessed the infrastructural facilities using an observational checklist. Expert microbiologist cross checked the microscopy report done by the laboratory technicians. It revealed that retrieval mechanism was not functioning in more than half of the DOT centers. Only 5 DOT providers were trained in RNTCP. Stock of sputum containers, methylene blue, and carbol fuchsin was found to be inadequate at some microscopy centers. Half of the laboratory technicians reported high false positive result in spite of being trained. Improvement of infrastructural and logistic support along with the refreshing training for the workers are needed for effective implementation of RNTCP.

    Recent floods along the Atlantic and Gulf seaboards and elsewhere in the world before Katrina had demonstrated the complexity of public health impacts including trauma; fires; chemical, sewerage, and corpse contamination of air and water; and diseases. We realized that Louisiana's vulnerability was exacerbated because forty percent of the state is coastal zone in which 70% of the population resides. Ninety percent of this zone is near or below sea level and protected by man-made hurricane-protection levees. New Orleans ranked among the highest in the nation with respect to potential societal, mortality, and economic impacts. Recognizing that emergency responders had in the past been unprepared for the extent of the public health impacts of these complex flooding disasters, we created a multi-disciplinary, multi-campus research center to address these issues for New Orleans. The Louisiana Board of Regents, through its millennium Health Excellence Fund, awarded a 5-year contract to the Center in 2001. The research team combined the resources of natural scientists, social scientists, engineers, and the mental health and medical communities. We met annually with a Board of Advisors, made up of federal, state, local government, and non-governmental agency officials, first responders and emergency managers. Their advice was invaluable in acquiring various datasets and directing aspects of the various research efforts. Our center developed detailed models for assessment and amelioration of public health impacts due to hurricanes and major floods. Initial research had showed that a Category 3 storm would cause levee overtopping, and that most levee systems were unprotected from the impacts of storm-induced wave erosion. Sections of levees with distinct sags suggested the beginnings of foundation and subsidence problems. We recognized that a slow moving Cat 3 could flood up to the eaves of houses and would have residence times of weeks. The resultant mix of sewage, corpses

    Full Text Available Nebulized colistin (NC is used for the treatment of pneumonia due to multidrug-resistant Gram-negative bacteria. In this one-year case-control study, our objective was to evaluate the effect of NC on the ventilator circuit (VC components. The case group consisted of 25 mechanically-ventilated patients who received NC, while the control group was 25 mechanically-ventilated patients who did not receive NC. Respiratory therapists inspected the VC every 4 hrs and whenever a ventilator alarm was reported. The VC component was changed if the alarm did not subside after necessary measures were performed. Patients from both groups were treated at the adult ICU in King Hussein Cancer Center (KHCC. In the case group, 22(88% patients required changing at least one of the circuit components (flow sensor, exhalation membrane, or nebulizer kit. The median number of changes (range per patient of the flow sensor, exhalation membrane, and nebulizer kit were: 2(1-3, 2(1-6, and 1(1-2, respectively. Large amounts of white crystals, which resembled the colistin powder, were reported on the replaced VC components. The flow sensor was changed in 2 control patients, but white crystals were absent. Crystals obtained from one case subject were confirmed to be colistin by chromatographic mass spectroscopy. Further studies are needed to evaluate the effect of crystal formation on the efficacy of NC and clinical outcomes.

    Full Text Available Abstract Introduction A retropharyngeal abscess is a potentially life-threatening infection in the deep space of the neck, which can compromise the airway. Its management requires highly specialized care, including surgery and intensive care, to reduce mortality. This is the first case of a gas-forming abscess reported from this region, but not the first such report in the literature. Case presentation We present a case of a 16-month-old Yoruba baby girl with a gas-forming retropharyngeal abscess secondary to fish bone foreign body with laryngeal spasm that was managed in the recovery room. We highlight specific problems encountered in the management of this case in a resource-challenged center such as ours. Conclusion We describe an unusual presentation of a gas-forming organism causing a retropharyngeal abscess in a child. The patient's condition was treated despite the challenges of inadequate resources for its management. We recommend early recognition through adequate evaluation of any oropharyngeal injuries or infection and early referral to the specialist with prompt surgical intervention.

    Full Text Available At the infant-toddler center, the rituals of transition that mark children’s arrival and going home times offer interesting kaleidoscopes for the study of interactive dynamics with the associated meanings and implicit educational models. Numerous pedagogical studies have investigated the meanings of these events, for the most part drawing on the monocultural model of classical attachment theory to analyze interactions between adults and children. Far less research has approached these rituals using triadic, systemic and intercultural categories of analysis in order to explore not only educators’ actions but also what is going on in their minds. In this paper, we discuss examples from a recent study on rituals of transition in the multicultural context of an infant toddler center, combining description of the timing, behaviors and interactive styles of children and adults, with analysis of the thoughts and representations of the educators.

    Healthcare in America continues to be of paramount importance, and one of the most highly debated public policy issues of our time. With annual expenditures already exceeding $2.4 trillion, and yielding less than optimal results, it stands to reason that we must turn to promising tools and solutions, such as information technology (IT), to improve service efficiency and quality of care. Presidential addresses in 2004 and 2008 laid out an agenda, framework, and timeline for national health information technology investment and development. A national initiative was long overdue. This report we show that advancements in both medical technologies and information systems can be capitalized upon, hence extending information systems usage beyond data collection to include administrative and decision support, care plan development, quality improvement, etc. In this paper we focus on healthcare services for palliative patients. We present the development and preliminary accounts of a successful initiative in the Medical Center of Central Georgia where footprints information technology was modified and integrated into the hospital's palliative care service and existing EMR systems. The project provides evidence that there are a plethora of areas in healthcare in which innovative application of information systems could significantly enhance the care delivered to loved ones, and improve operations at the same time..

    The offer of "integrative oncology" is one option for clinics to provide safe and evidence-based complementary medicine treatments to cancer patients. As known from merger theories, corporate culture and integration models have a strong influence on the success of such integration. To identify relevant corporate culture aspects that might influence the success in two highly visible integrative oncology clinics, we interviewed physicians, nurses, practitioners, and managers. All interviews (11 in a German breast cancer clinic and 9 in an integrative medicine cancer service in the USA) were audio-recorded, transcribed and analyzed with content analysis. According to the theoretical framework of mergers, each clinic selected a different integration type ("best of both worlds" and "linking"). Nonetheless, each developed a similar corporate culture that has a strong focus on research and safe and evidence-based treatments, and fosters a holistic and patient-centered approach. Structured communication within the team and with other departments had high relevance. Research was highlighted as a way to open doors and to facilitate a more general acceptance within the hospital. Conventional physicians felt unburdened by the provision of integrative medicine service but also saw problems in the time required for scheduled treatments, which often resulted in long waiting lists.

    Full Text Available Abstract Background Behavioral health services for children and adolescents in the U.S. are lacking in accessibility, availability and quality. Evidence-based interventions for emotional and behavioral disorders can improve quality, yet few studies have systematically examined their implementation in routine care settings. Methods Using quantitative and qualitative data, we evaluated a multi-faceted implementation strategy to implement cognitive-behavioral therapy (CBT for depressed adolescents into two publicly-funded mental healthcare centers. Extent of implementation during the study's duration and variables influencing implementation were explored. Results Of the 35 clinicians eligible to participate, 25 (71% were randomized into intervention (n = 11 or usual care (n = 14. Nine intervention clinicians completed the CBT training. Sixteen adolescents were enrolled in CBT with six of the intervention clinicians; half of these received at least six CBT manually-based sessions. Multiple barriers to CBT adoption and sustained use were identified by clinicians in qualitative interviews. Conclusion Strategies to implement evidence-based interventions into routine clinical settings should include multi-method, pre-implementation assessments of the clinical environment and address multiple barriers to initial uptake as well as long-term sustainability.

    Renal transplantation has become an effective form of treatment for end-stage renal failure. Unfortunately, as a consequence of immunological and nonimmunological pathogenic mechanisms, chronic allograft nephropathy is responsible for the loss of a large proportion of kidney grafts after several years and return to dialysis. We have reported herein our 24 years of experience with second kidney transplantations. Of 1,302 kidney transplantations between January 1983 and June 2007 performed in our transplantation center, 100 were second transplantations. Kidney retransplantation was performed in 74 men and 26 women of overall mean age of 35.4 +/- 12.6 years. Cadaveric donor grafts were transplanted in 92 patients, whereas the remaining 8 were living-related donor kidneys. At 1, 5, and 10 years after kidney transplantation, patient survival rates were 100%, 96%, and 92%, respectively, whereas graft survival rates were 85%, 72%, and 53%, respectively. Immunosuppressive therapy included induction therapy with polyclonal anti-lymphocyte antibodies (ALG/ATG) or (starting from 1999) monoclonal anti CD 25 antibody. Our results demonstrated good outcomes for kidney retransplantations with allocation based on anti- HLA antibody identification together with induction immunosuppression.

    Acquired hemophilia A (AHA) is a rare bleeding disorder caused by the autoantibody directed against factor VIII in patients without previous history of a bleeding disorder. We retrospectively analyzed the characteristics and outcomes of 49 patients with AHA diagnosed in our center from February 1994 to October 2012. Twenty-four patients with acute bleeding episodes were treated with prothrombin complex concentrate (PCC) at a relative low dose of 30 to -50 U/kg/d and achieved good outcomes without any adverse reaction. Corticosteroids alone or in combination with cyclophosphamide were used as the first-line therapy to eradicate the inhibitors. In 39 evaluable patients, 35 (89.7%) achieved complete remission (CR). This study demonstrates that when bypassing agents such as recombinant activated factor VII and activated PCCs are not affordable or available, low dose PCC is effective and safe to control acute bleeding in patients with AHA. First-line therapy achieved good outcomes with a CR rate of 89.7%.

    Purpose: An evaluation of dose-response relationship and an attempt to define predictive factors. Methods and Materials: A total of 137 cases of painful vertebral hemangioma irradiations (101 patients). Fraction dose (fd) varied from 2 to 15 Gy (123 fractionated and 14 radiosurgical treatments), and total dose (TD) from 8 to 30 Gy (111 cases irradiated with fd of 2 GY to TD of 24 Gy). We evaluated pain relief, changes in analgesic requirements, and reossification. Results: Means of pain relief 1, 6, 12, and 18 months after radiotherapy (defined as a decrease of primary pain level expressed in percent) were 60.5%, 65.4%, 68.3%, and 78.4%, respectively. Proportion of patients with no need for analgesics and patients using tramadol were 39%, 40%, 44%, 57%, and 20%, 17%, 22%, and 11% in these times. The proportion of patients experiencing complete/partial pain relief changed from 36/48% 1 month, to 64/22% 1.5 years after radiotherapy. No impact of radiotherapy on reossification was found. The positive impact of fd and TD increase for analgesics uptake reduction and pain relief was found. An increase of the fd by 1 Gy results in 27% chance of analgesics uptake reduction and 3.8% reduction of pain, whereas 14% analgesics uptake reduction and 2.2% of pain reduction in case of the TD. The predictive factors improving results were found: female gender, older age, better performance states (the chance of the lower analgesic treatment decreases over 2.5 times in comparison to the higher Zubrod degree), bigger Hb concentration, shorter symptoms duration and lower analgesics uptake before radiotherapy. Conclusions: The obtained data support the efficacy of radiotherapy in improving pain secondary to vertebral hemangioma, with the degree of pain amelioration being related to increasing fd and TD. The positive predictive factors were defined: female gender, older age, better performance status, increased Hb concentration, shorter symptoms duration, and lower analgesics uptake

    Laparoscopic radical prostatectomy is considered the first treatment of choice for local prostate cancer due to its minimal invasion advantage. To further achieve the goal of minimal invasion, single port laparoscopic radical prostatectomy has been developed to minimize the complications associated with puncture tracks. The aim of this study was to illustrate the technique for single port laparoscopic radical prostatectomy and evaluate its efficacy and safety. We reported 8 cases of radical prostatectomy with excellent early outcome carried out in Shanghai Changzheng Hospital from June 2009 to August 2009 using a home-made multiple instrument access port and adding an additional small incision at McBumey point.

    Full Text Available Abstract Background Following the demise of Jordan's King Hussein bin Talal to cancer in 1999, the country's Al-Amal Center was transformed from a poorly perceived and ineffectual cancer care institution into a Western-style comprehensive cancer center. Renamed King Hussein Cancer Center (KHCC, it achieved improved levels of quality, expanded cancer care services and achieved Joint Commission International accreditation under new leadership over a three-year period (2002–2005. Methods An exploratory case research method was used to explain the rapid change to international standards. Sources including personal interviews, document review and on-site observations were combined to conduct a robust examination of KHCC's rapid changes. Results The changes which occurred at the KHCC during its formation and leading up to its Joint Commission International (JCI accreditation can be understood within the conceptual frame of the transformational leadership model. Interviewees and other sources for the case study suggest the use of inspirational motivation, idealized influence, individualized consideration and intellectual stimulation, four factors in the transformational leadership model, had significant impact upon the attitudes and motivation of staff within KHCC. Changes in the institution were achieved through increased motivation and positive attitudes toward the use of JCI continuous improvement processes as well as increased professional training. The case study suggests the role of culture and political sensitivity needs re-definition and expansion within the transformational leadership model to adequately explain leadership in the context of globalizing health care services, specifically when governments are involved in the change initiative. Conclusion The KHCC case underscores the utility of the transformational leadership model in an international health care context. To understand leadership in globalizing health care services, KHCC

    BACKGROUND: Acute pancreatitis is a relatively rare but po-tentially lethal complication after transarterial chemotherapy. This study aimed to review the complications such as acute pancreatitis after transarterial chemotherapy with or without embolization for hepatocellular carcinoma. METHODS: A total of 1632 patients with hepatocellular car-cinoma who had undergone transarterial chemoembolization from January 2000 to February 2014 in a single-center were reviewed retrospectively. We investigated the potential com-plications of transarterial chemoembolization, such as acute pancreatitis and acute pancreatitis-related complications. RESULTS: Of the 1632 patients with hepatocellular carcinoma who had undergone 5434 transarterial chemoembolizations, 1328 were male and 304 female. The median age of these pa-tients was 61 years. Most (79.6%) of the patients suffered from HBV-related hepatocellular carcinoma. The median tumor size was 5.2 cm. Of the 1632 patients, 145 patients underwent transarterial chemoembolization with doxorubicin elut-ing bead, making up a total of 538 episodes. The remaining patients underwent transarterial chemoembolization with cisplatin. Seven (0.4%) patients suffered from acute pancre-atitis post-chemoembolization. Six patients had chemoembo-lization with doxorubicin and one had chemoembolization with cisplatin. Patients who received doxorubicin eluting bead had a higher risk of acute pancreatitis [6/145 (4.1%) vs 1/1487 (0.1%), P CONCLUSIONS: Acute pancreatitis after transarterial chemo-embolization could result in serious complications, especially after treatment with doxorubicin eluting bead. Continuation of current treatment with transarterial chemoembolization after acute pancreatitis is feasible providing the initial attack is completely resolved.

    Background No definitive conclusions have been drawn from the available data about the utilization of extracorporeal membrane oxygenation (ECMO) to treat severe acute respiratory distress syndrome (ARDS). The aim of this study was to review our center’s experience with ECMO and determine predictors of outcome from our Chinese center. Material/Methods We retrospectively analyzed a total of 23 consecutive candidates who fulfilled the study entry criteria between January 2009 and December 2015. Detailed clinical data, ECMO flow, and respiratory parameters before and after the introduction of ECMO were compared among in-hospital survivors and nonsurvivors; factors associated with mortality were investigated. Results Hemodynamics and oxygenation parameters were significantly improved after ECMO initiation. Thirteen patients survived to hospital discharge. Univariate correlation analysis demonstrated that APACHE II score (r=−0.463, p=0.03), acute kidney injury (r=−0.574, p=0.005), membrane oxygenator replacement (r=−0.516, p=0.014) and total length of hospital stay (r=0.526, p=0.012) were significantly correlated with survival to hospital discharge, and that the evolution of the levels of urea nitrogen, platelet, and fibrinogen may help to determine patient prognosis. Sixteen patients referred for ECMO from an outside hospital were successfully transported to our institution by ambulance, including seven transported under ECMO support. The survival rate of the ECMO-transport group was comparable to the conventional transport or the non-transport group (both p=1.000). Conclusions ECMO is an effective alternative option for severe ARDS. APACHE II score on admission, onset of acute kidney injury, and membrane oxygenator replacement, and the evolution of levels of urea nitrogen, platelet, and fibrinogen during hospitalization may help to determine the in-hospital patient prognosis. By establishing a well-trained mobile ECMO team, a long-distance, inter

    Full Text Available Introduction: The universal target under the Millennium Development Goals (MDGs is to reduce the worldwide burden of tuberculosis (TB 2015, and we wanted to evaluate development in TB control by assessment of the time trend in incidence and death rate in Tabriz, Iran. Methods: This was a retrospective trend analysis of the data have been recorded in East Azerbaijan State TB center during 10 years. Data were related to patients have been registered for treatment under the directly observed treatment, short-course (DOTS strategy from 2001 to 2011. Results: In total, 3283 TB patients were treated under DOTS strategy during 2001-2011. Males constituted 55.0% of subjects. The risk was the highest among the productive age group (15-44 years. About 61.0% of cases had pulmonary, and 78.0% of pulmonary TB patients were found to be the sputum smear positive than 46.0% of them were new sputum smear positive, and 2.0% of them were relapse. On average, for sputum smear positive, TB cases from 2005 to 2011; the treatment success rate was 87.3%; the cure rate was 80.2%; the treatment failure rate was 0.5% and death rate was 10.3%. In general, the TB incidence rate for all TB cases was decreased from 11.9-8.1 a 100000 population and the smear-positive pulmonary TB incidence rate were decreased from 4.7 to 4.1 a 100000 population in eastern Azerbaijan province during 2001-2011. Conclusion: In general, we had a decrease in the incidence rate for all of TB cases. In addition, we had a fall in cure rate and had an increase in drug side effects rate in this year that can be because of elevated old people ratio and high death rate by other indirect causes and lack of regular visits and medications taking according to the treatment protocol.

    BACKGROUND Magnetic resonance enterography (MRE) has become the modality of choice in assessment of patients with Crohn’s disease (CD). We aimed to present our experience on 300 patients with CD who underwent MRE during the first 30 months after setting up MRE for the first time in a referral center in Iran. METHODS Patients with a definite diagnosis of CD based on either ileocolonoscopy or histopathological studies were included in the final report and categorized into four phenotypes of inactive, active, stricturing, and penetrating disease. RESULTS This was a case series study on 300 patients with known CD out of 594 referred subjects. The most prevalent phenotype was inactive observed in 162 (54.0%) patients followed by stricturing in 44 (14.7%), active in 40 (13.3%), penetrating in 27(9%), and active on chronic in 27 (9%) cases. The number of referred patients increased from 51 cases in the first 6 months to 165 in the last 6 months. CONCLUSION This study presents the first report on the application of MRE in Iran as superb modality for management of CD. The growing number of referred patients indicates that MRE has been successful in addressing the most critical concerns of clinicians on determining the dominant disease phenotype. PMID:27957290

    Relapsing polychondritis (RP) is an autoimmune disorder characterized by inflammation in cartilaginous structures including the ears, noses, peripheral joints, and tracheobronchial tree. It rarely involves the central nervous system (CNS) but diagnosis of CNS complication of RP is challenging because it can present with varying clinical features. Herein we report 3 cases of relapsing polychondritis involving CNS with distinct manifestations and clinical courses. The first patient presented with rhombencephalitis resulting in brain edema and death. The second patient had acute cognitive dysfunction due to limbic encephalitis. He was treated with steroid pulse therapy and recovered without sequelae. The third patient suffered aseptic meningitis that presented as dementia, which was refractory to steroid and immune suppressive agents. We also reviewed literature on CNS complications of RP.

    Full Text Available Abstract Background Pulmonary tuberculosis (TB is a major health problem worldwide. Detection of the most infectious cases of tuberculosis – sputum smear-positive pulmonary cases – by passive case finding is an essential component of TB control. The district of Sidoarjo in East Java reported a low case detection rate (CDR of 14% in 2003. We evaluated the diagnostic process for TB in primary health care centers (PHC in Sidoarjo district to assess whether problems in identification of TB suspects or in diagnosing TB patients can explain the low CDR. Methods We performed interviews with the staff (general nurse, TB worker, laboratory technician, and head of health center of the 25 PHCs of Sidoarjo district to obtain information about the knowledge of TB, health education practices, and availability of support services for TB diagnosis. The quality of the laboratory diagnosis was examined by providing 10 slides with a known result to the laboratory technicians for re-examination. Results Eighty percent of the nurses and 84% of the TB workers knew that cough >3 weeks can be a symptom of TB. Only 40% of the nurses knew the cause of TB, few could mention complications of TB and none could mention the duration of infectiousness after start of treatment. Knowledge of TB workers was much better. Information about how to produce a good sputum sample was provided to TB suspects by 76% of the nurses and 84% of the TB workers. Only few provided all information. Fifty-five percent of the 11 laboratory technicians correctly identified all positive slides as positive and 45% correctly identified 100% of the negative slides as negative. All TB workers, one general nurses and 32% of the laboratory technicians had received specific training in TB control. There has been no shortage of TB forms and laboratory materials in 96% of the PHCs. Conclusion The quality of the diagnostic process for TB at PHC in Sidoarjo district should be improved on all levels

    In ethylenediaminetetraacetic acid (EDTA)-dependent pseudothrombocytopenia (PTCP), automated platelet counts are lower than actual counts because of EDTA-induced aggregation. Factors contributing to the incidence of EDTA-PTCP are unknown, and no study has assessed the prognosis of EDTA-PTCP patients. This retrospective study assessed characteristics in EDTA-PTCP patients and matched controls to determine differences in prognosis. A retrospective case-control study was designed. From the University of Tokyo Hospital database, we identified patients diagnosed with EDTA-PTCP between 2009 and 2012, and performed 1:2 case:control matching for age and sex. A control group of sex- and age-matched patients was selected at random from the same database. We investigated differences in the frequency of complications, medication history, and blood transfusion history between the groups at the time of blood collection. Prognosis was evaluated using multivariate Cox regression analysis adjusting for age, sex, autoimmune disease, liver disease, and malignant tumor. We identified 104 EDTA-PTCP patients and 208 matched controls. The median age was 69.0 years (interquartile range: 54-76), with men comprising 51%. EDTA-PTCP patients had a higher frequency of malignant tumor and a lower frequency of hypertension and diabetes than controls. After adjustment for background factors, prognosis of EDTA-PTCP patients was significantly poorer than controls (hazard ratio, 11.8; 95% confidence intervals, 2.62-53.54). In conclusion, EDTA-PTCP patients had higher mortality, and EDTA-PTCP may need to be recognized as an indicator of worse prognosis.

    Objective: To investigate application of cardiopulmonary resuscitation (CPR) measures within the golden minutes in Europe. Methods: The collected data belong to the patients with cardiac arrest that have been recorded in patients’ protocol logbook at the Emergency Clinic. During the 2010-2011 in the Emergency Center of the CUCK in Prishtina have been treated a total of 269 patients with cardiac arrest, of whom 159 or 59.1% have been treated in 2010, and 110 patients or 40.9% in 2011. Cardiac arrest cases were present during all days of the week, but most frequently cases have been reported on Monday with 32.0% of cases, and on Friday with 24.5% of cases. All patients with cardiac arrest have been treated with physiological solution. Results: In 245 or 91.1% patients adrenaline has been applied; in 64 or 23.8% amiodarone has been applied; in 12 or 4.5% cases atropine has been applied, 11 or 4.1% of cases were treated with NaHCO3; 7 or 2.6% of cases were treated with lidocaine; and 6 or 2.2% of cases were treated with dopamine. All survivors from cardiac arrest have received appropriate medical assistance within 10 minutes from attack, which implies that if cardiac arrest occurs near an health care institution (with an opportunity to provide the emergent health care) the rate of survival is higher. Conclusions: Anti-arrhythmic drugs as with vasopressors, the evidence that anti-arrhythmic drugs are of benefit in cardiac is limited. No anti-arrhythmic drug given during human cardiac arrest has been shown to increase survival to hospital discharge, although amiodarone has been shown to increase survival to hospital admission after shock-refractory VF/VT. There are no data on the use of amiodarone for shock-refractory VF/VT when single shocks are used. Despite the lack of human long-term outcome data, the balance of evidence is in favour of the use of some anti-arrhythmic drugs for the management of arrhythmias in cardiac arrest.

    The summary. On the basis of geodynamic model of the forced relative displacement of the centers of mass of the core and the mantle of the Earth the secular variations of a gravity and heights of some gravimetry stations on a surface of the Earth have ben studied. At the account of secular drift of the center of mass of the Earth which on our geodynamic model is caused by the unidirectional drift of the core of the Earth relatively to the mantle, the full explanation is given to observable secular variations of a gravity at stations Ny-Alesund (Norway), Churchill (Canada), Medicine (Italy), Sayowa (Antarctica), Strastburg (France), Membach (Belgium), Wuhan (China) and Metsahovi (Finland). Two new methods of determination of secular drift of the center of mass of the Earth, alternative to classical method of a space geodesy are offered: 1) on the basis of gravimetry data about secular trends of a gravity at the stations located on all basic regions of the Earth; 2) on the basis of the comparative analysis of altimetry and coastal data about secular changes of sea level also in basic regions of ocean. 1. Secular drift of the center of mass of the core and the center of mass of the Earth. A secular drift of the center of mass of the Earth to the North relatively to special center O on an axis of rotation of the Earth for which the coefficient of third zonal harmonic J3' = 0, has been predicted in the author work [1]. A drift in a direction to a geographical point (pole P) 70°0 N and 104°3 E has been established for the first time theoretically - as a result of the analysis of the global directed redistribution of masses of the Earth, explaining the observed secular drift of the pole of an axis of rotation of the Earth and not tidal acceleration of its axial rotation [2]. In [1] velocity of drift it has been estimated in 1-2 cm/yr. For specified center O the figure of a planet is as though deprived of pure-shaped form (J3' = 0). And in this sense the point O can be

    Full Text Available Objective: To analyze the perioperative outcome of the first 190 cases of robot-assisted laparoscopic radical prostatectomy performed at our center from July 2006 to December 2010. Materials and Methods: Operative and recovery data for men with localized prostate cancer undergoing robot-assisted radical prostatectomy at our center were reviewed. All surgeries were performed using the 4-arm da Vinci-S surgical robot. Preoperative data included age, body mass index (BMI, prostate specific antigen (PSA level, prostate weight, biopsy Gleason score and TNM staging, while operative and recovery data included total operative time, estimated blood loss, complications, hospital stay and catheter time. These parameters were evaluated for the safety and efficacy of this procedure in our center. Results: The mean age of our patients was 65 ± 1.2 years. The mean BMI was 25.20 ± 2.88 and the median PSA was 14.8 ng/ml. Majority of our patients belonged to clinical stage T2 (51.58%. The mean total operative time was 166.44 ± 11.5 min. Six patients required conversion to open procedure and there was one rectal injury. The median estimated blood loss was 302 ± 14.45 ml and the median duration of hospital stay was 4 days. The overall margin positivity rate was 12.63%. Conclusion: Despite our limited robotic surgery experience, our perioperative outcome and complication rate is comparable to most contemporary series. Robot-assisted laparoscopic prostatectomy (RALP is easy to learn and provides the patient with the benefits of minimally invasive surgery with minimal perioperative morbidity.

    Full Text Available Background and Design: Bullous pemphigoid (BP is a chronic, autoimmune, subepidermal blistering disease. The aim of this study was to determine the clinico-epidemiologic data’s of patients diagnosed as BP in our clinic and compare these data with other studies in our country and in the world. Material and Method: We researched the documents of BP cases diagnosed by clinical and histopathological examinations from January 2009 to January 2013, retrospectively. We evaluated clinical and dermographical characteristics of all patients such as age, sex, existence of oral mucosal lesions, association of pruritus, duration of disease, presence of triggering factors, features of skin lesions, results of direct immunofluorescence (DIF investigation, drug intake, recurrence and mortality rates and causes of detected mortality. Results: Of the 29 patients included in the study %48,3 were female, %51,7 were male. The average age was 70,17 and the mean duration of disease was 15.41 months. In five cases oral mucosal involvement and in 24 cases pruritus was detected. Drugs in three cases and malignity in one case were assessed as triggering factors. The results of DIF investigation revealed the linear IgG and C3 deposition at the dermoepidermal junction in 12 cases, C3 deposition in 10 cases. The initial treatment was topical corticosteroid in 11, tetracycline and nicotinamide combination in six, systemic corticosteroid in 10 individuals. After initial therapy recurrence appeared in 7 patients in one year. Mortality during hospitalization was observed in 2 cases. Conclusions: We presented the clinical and epidemiological features of patients diagnosed as BP in our clinics in the last three years. Because of having different ethnical originated, heterogeneous population of our city, we believe that our investigation will contribute to having opinion about epidemiology of BP in our country. Nevertheless, prospective, long term and multicentre studies based on

    Full Text Available Taking into consideration satisfied customer as necessary for business maintenance, companies are trying to discover determinants which have the biggest influence on their consumer satisfaction. Here are presented two factors that have influence on consumer satisfaction in shopping centers: quality of shopping and corporate social responsibility. In this research, each of these factors had six elements. The results of the regression analysis are that “Value for money in stores” (beta=0.387, p=0.000 has the greatest impact on satisfaction when shopping quality performance is concerned, and that “Retailer support for (national/local cultural and sport events“ (beta=0.333, p<0.001 has the greatest impact on satisfaction in the case of CSR performance. Further analysis showed the difference in consumer perception of corporate social responsibility, depending on their occupation and level of education. It is also important to mention that consumers with environment and empathic concern have higher scores perception of CSR. However, there is not statistically important difference in consumer perception of shopping quality in shopping centers

    Full Text Available This paper illustrates how our development team has used some information technologies to let physicians obtain an instant abnormal laboratory result report for critical patient care services. We have implementeda healthcare message alerting system (HMAS on a healthcare short message service (HSMS engine and the distributed healthcare-oriented service environment (DiHOSE in the National Taiwan University Hospital (NTUH. The HSMS engine has a general interface for all applications which could easily send any kind of alerting messages. Fundamentally, the DiHOSE uses HL7 standard formats to process the information exchange behaviors and can be flexibly extended for reasonable user requirements. The disease surveillance subsystem is an integral part of NTUH new hospital information system which is based on DiHOSE and the disease surveillance subsystem would send alerting messages through the HSMS engine. The latest cell phone message alerting subsystem, a case study, in NTUH proved that the DiHOSE could integrate the user required functions without much work. We concluded that both HSMS and DiHOSE can generalize and extend application demands efficiently.

    Full Text Available Objective: Idiopathic chronic eosinophilic pneumonia (ICEP is a rare eosinophilic lung disorder with an unknown etiology and is characterized by subacute or chronic respiratory and general symptoms, alveolar and/or peripheral eosinophilia, and the accumulation of eosinophils in the lungs. We aimed to present diagnostic test results and follow-up outcomes of 17 patients who were diagnosed with ICEP in our hospital in light of literature. Methods: Between 2008 and 2013, we examined 17 cases of ICEP. We evaluated clinical and laboratory findings together with the long-term follow-up data. Results: The patients had a mean age of 40.8 years at presentation, and the female/male ratio was 0.8. The most common symptoms were cough (94%, shortness of breath (76%, and high fever (35%. Bronchoalveolar lavage eosinophil percentages of the patients ranged from 3% to 80%. Nine (53% patients experienced recurrence. Six patients were maintained on low dose steroid due to repeating relapses. Among these patients, 7 (77.7% had a total IgE level of above 500/IU/mL. Conclusion: Relapses are common in ICEP after the withdrawal of corticosteroid treatment or during dose reduction. We point out the importance of the close monitoring of patients for identifying relapse. A higher total IgE level during diagnosis may serve as a predictor of recurrence.

    Full Text Available Acute ischemic stroke (AIS due to thrombo-embolic occlusion in the cerebral vasculature is a major cause of morbidity and mortality in the United States and throughout the world. Although the prognosis is poor for many patients with AIS, a variety of strategies and devices are now available for achieving recanalization in patients with this disease. Here, we review the treatment options for cerebrovascular thromboembolic occlusion with a focus on the evolution of strategies and devices that are utilized for achieving endovascular clot extraction. In order to demonstrate the progression of this treatment strategy over the past decade, we will also present a single-center case series of AIS patients treated with endovascular thrombectomy.

    Longitudinal sleeve gastrectomy (LSG) has been validated for the treatment of morbid obesity. However, treatment failures can appear several months after SG. Additional malabsorptive surgery is generally recommended in such cases. The objective of the present study was to evaluate the outcomes of repeat SG (re-SG) relative to first-line SG. This was a retrospective study included 15 patients underwent re-SG after failure of first-line SG (i.e. University Hospital, France; Public Practice). These patients were matched (for age, gender, body mass index and comorbidities) 1:2 with 30 patients having undergone first-line SG. The efficacy criteria comprised intra-operative data and postoperative data. The overall study population comprised 45 patients. The re-SG and first-line SG groups did not differ significantly in terms of median age (p = NS). The median BMI was similar in the two groups (43 kg/m(2) vs. 42.3 kg/m(2), p = NS). The two groups were similar in terms of the prevalence of comorbidities. The mean operating time was longer in the re-SG group (116 vs. 86 min; p ≤ 0.01). The postoperative complication rate was twice as high in the re-SG group (p = 0.31). Two patients in the re-SG group developed a gastric fistula (p = 0.25) and one of the latter died. At 12 months, the Excess Weight Loss was 66% (re-SG group) and 77% (first-line SG group) (p = 0.05). Re-SG is feasible but appears to be associated with a greater risk of complications. Nevertheless, re-SG can produce results (in terms of weight loss), equivalent to those obtained after first-line SG.

    Full Text Available Background and purpose : Penile fracture is the rupture of the corpus cavernousum due to trauma to the erect penis , which has various background etiologies in different countries according to their habits. The aim of this study was to determine and evaluate the frequency, etiologies and complications of penile fracture in our geographic area.Material and Methods : This analytical-cross sectional study was performed via census sampling among men referred to Sh. Beheshti Hospital of Babol Medical University during 1995 to 2004. Data were analyzed by Chi-Square, Fisher`s exact and T-test using SPSS release 12.Results : 84 patients with penile fracture (mean age of 18.1 years were studied. The frequency was higher in single patients (78% than married ones. The most important complaint of patients with penile fracture was penile pain (36%, hematoma (30%, and penile swelling (12%. Background factors were manipulation of erect penis (74%, sexual intercourse (18% trauma to erect pennies (8%. Urethral ruptures were seen in 8% of all patients with feacture. There were significant differences between urethral rupture and background etiologies (P=0.000 and marrital status (p=0.000 as 90% of the cases were single patient, referred to hospital due to manipulation of erect pennies (P=0.000.Conclusion : High frequency of penile manipulation among young boys in the study area in comparison with other studies results in penile fracture but subsequent urethral rupture was uncommon among men. Better and earlier diagnosis of penile fracture is related to determination of background etologies in the patients.

    Paederus sp. is a beetle belonging to Staphylinidae family and Coleoptera order. Its distribution is worldwide, especially in hot climates. Over 600 species of Paederus are known, approximately 50 are able to cause an irritant contact dermatitis. When the beetle is accidentally crushed on the skin, it releases pederin, a potent toxin with vesicating action. In Europe, only anecdotical cases of Paederus sp. dermatitis have been reported. Since 1993, we have observed approximately 25 patients with suspected Paederus sp. dermatitis. In 9 the clinical diagnosis was confirmed because Paederus fuscipes were found. The case list includes 6 males and 3 females, ages ranging from 6 to 53 years (mean age: 26.3 years). Six patients presented with one lesion and 3 with 2 lesions. Eyelids (3 patients), shoulders (3), neck (2), cheek (1), breast (1), back (1) and calf (1) were involved. All patients showed erythema, 2 oedema, 2 blisters, 1 vesicles, 1 pustules and 1 crusts. In the patient with pustules, bacteriological examinations were negative. A biopsy was carried out in 4 patients. In the early stages, spongiosis with exocytosis of neutrophils was observed. Vesicles with neutrophils and necrosis of the epidermis were typical of the advanced stage. Oedema of the dermis and a mixed infiltrate, with eosinophils, neutrophils and lymphocytes, in the papillary and upper reticular dermis, were also observed. Direct immunofluorescence was negative in all patients. Paederus sp. should also be considered in temperate climates as a possible aetiological agent in cases of acute dermatitis.

    The detection of gamma-rays from the source HESS J1745-290 in the Galactic Center (GC) region with the H.E.S.S. array of Cherenkov telescopes in 2004 is presented. After subtraction of the diffuse gamma-ray emission from the GC ridge, the source is compatible with a point-source with spatial extent less than 1.2'(stat.) (95% CL). The measured energy spectrum above 160 GeV is compatible with a power-law with photon index of 2.25 +/- 0.04(stat.) +/- 0.10 (syst.) and no significant flux variation is detected. These measurements are discussed in the framework of dark matter annihilation. It is found that the bulk of the VHE emission must have non-dark-matter origin. Loose constraints on the velocity-weighted annihilation cross section are derived assuming the presence of an astrophysical non-dark-matter gamma-ray contribution.

    Direct conversion of methane to value-added chemicals remains a challenge from both scientific and industrial points of view. In 1993, Wang et al. reported that methane can be transformed into aromatics on Mo/HZSM-5 catalysts under non-oxidative condition.1 Although remarkable progress has been made in the studies of the methane dehydroaromatization (MDA) reaction since that time, the reaction mechanism is still being debated,2 mainly due to the lack of understanding of the active center on Mo/HZSM-5 catalysts.3 It has been hypothesized that molybdenum may migrate into zeolitic channels and anchor on Brönsted acid sites during the synthesis. However, it is unclear whether the active molybdenum species are small crystallites or isolated exchanged species.

    Full Text Available To analyze the occurrence, risk factors, treatment and prognosis of postoperative pleural effusion after spinal deformity correction surgery.The clinical and imaging data of 3325 patients undergoing spinal deformity correction were collected from the database of our hospital. We analyzed the therapeutic process of the 28 patients who had postoperative pleural effusion, and we identified the potential risk factors using logistic regression.Among the 28 patients with postoperative pleural effusion, 24 (85.7% suffered from hemothorax, 2 (7.1% from chylothorax, and 2 (7.1% from subarachnoid-pleural fistula. The pleural effusion occurred on the convex side in 19 patients (67.9%, on the concave side in 4 patients (14.3%, and on both sides in 4 patients (14.3%. One patient with left hemothorax was diagnosed with kyphosis. The treatment included conservative clinical observation for 5 patients and chest tube drainage for 23 patients. One patient also underwent thoracic duct ligation and pleurodesis. All of these treatments were successful. Logistic regression analysis showed that adult patients(≥18 years old, congenital scoliosis, osteotomy and thoracoplasty were risk factors for postoperative pleural effusion in spinal deformity correction surgery.The incidence of postoperative pleural effusion in spinal deformity correction surgery was approximately 0.84% (28/3325, and hemothorax was the most common type. Chest tube drainage treatment was usually successful, and the prognosis was good. Adult patients(≥18 years old, congenital scoliosis, and had undergone osteotomy or surgery with thoracoplasty were more likely to suffer from postoperative pleural effusion.

    Observations performed at the solar telescope-spectroheliograph, which has continuously automatically operated at MAS MAO RAS, were analyzed. Measurements of the activity index in the Ca II K line, which were performed according to the program of synoptic observations, are presented. The development of the solar flares observed at the center and on the wings of the Ca II K line was compared with observations in the X-ray and radio bands. It was shown that the time variations in the intensity in the 1-8 Å range according to the Geostationary Orbiting Environmental Satellites' (GOES) data and in the Ca II K line are close to each other and that the total X-ray flux and Ca II K intensity amplitude substantially correlate during the entire flare.

    A prospective protocol for treatment of malignant inoperable bowel obstruction was implemented at Grenoble University Hospital Center for 4 years. All 80 episodes of obstruction resulted from peritoneal carcinomatosis and none could expect another treatment cure. The protocol comprised three successive stages. Stage I included treatment for 5 days with a corticosteroid, antiemetic, anticholinergic, and analgesic. Stage II provided a somatostatin analogue if vomiting persisted. After 3 days, Stage III provided a venting gastrostomy. Obstruction relief with symptom control was obtained by medical treatment in 29 cases and symptom control occurred alone in an additional 32 cases. Ten patients were relieved by venting gastrostomy. Symptom control without permanent nasogastric tube (NGT) placement occurred in 72 episodes (90%). Eight patients with refractory vomiting were obliged to continue the NGT until death. Fifty-eight obstruction episodes (73%) were controlled in 10 days or less. Median time before gastrostomy was 17 days. Median survival was 31 days. This series suggests that a staged protocol for the treatment of inoperable malignant bowel obstruction is highly effective in relieving symptoms. A subgroup experiences relief of obstruction using this approach.

    2008-01-01

    We present lunar occultation observations obtained in August 2006 with the recently demonstrated burst mode of the ISAAC instrument at the ESO VLT. The results presented here follow the previously reported observations carried out in March 2006 on a similar but unrelated set of sources. Interstellar extinction in the inner regions of the galactic bulge amounts to tens of magnitudes at visual wavelengths. As a consequence, the majority of sources in that area are poorly studied and large numbers of potentially interesting sources such as late-type giants with circumstellar shells, stellar masers, infrared stars, remain excluded from the typical investigations which are carried out in less problematic regions. Also undetected are a large numbers of binaries. By observing LO events in this region, we gain the means to investigate at least a selected number of sources with an unprecedented combination of sensitivity and angular resolution. The LO technique permits to achieve mas resolution with a sensitivity of K...

    Full Text Available Most cases of sporadic primary hyperparathyroidism present disturbances in a single parathyroid gland and the surgery of choice is adenomectomy. Conversely, hyperparathyroidism associated with multiple endocrine neoplasia type 1 (hyperparathyroidism/multiple endocrine neoplasia type 1 is an asynchronic, asymmetrical multiglandular disease and it is surgically approached by either subtotal parathyroidectomy or total parathyroidectomy followed by parathyroid auto-implant to the forearm. In skilful hands, the efficacy of both approaches is similar and both should be complemented by prophylactic thymectomy. In a single academic center, 83 cases of hyperparathyroidism/ multiple endocrine neoplasia type 1 were operated on from 1987 to 2010 and our first surgical choice was total parathyroidectomy followed by parathyroid auto-implant to the non-dominant forearm and, since 1997, associated transcervical thymectomy to prevent thymic carcinoid. Overall, 40% of patients were given calcium replacement (mean intake 1.6 g/day during the first months after surgery, and this fell to 28% in patients with longer follow-up. These findings indicate that several months may be needed in order to achieve a proper secretion by the parathyroid auto-implant. Hyperparathyroidism recurrence was observed in up to 15% of cases several years after the initial surgery. Thus, long-term follow-up is recommended for such cases. We conclude that, despite a tendency to subtotal parathyroidectomy worldwide, total parathyroidectomy followed by parathyroid auto-implant is a valid surgical option to treat hyperparathyroidism/multiple endocrine neoplasia type 1. Larger comparative systematic studies are needed to define the best surgical approach to hyperparathyroidism/multiple endocrine neoplasia type 1.

    Most cases of sporadic primary hyperparathyroidism present disturbances in a single parathyroid gland and the surgery of choice is adenomectomy. Conversely, hyperparathyroidism associated with multiple endocrine neoplasia type 1 (hyperparathyroidism/multiple endocrine neoplasia type 1) is an asynchronic, asymmetrical multiglandular disease and it is surgically approached by either subtotal parathyroidectomy or total parathyroidectomy followed by parathyroid auto-implant to the forearm.

    Class I methanol masers are collisionally pumped and are generally correlated with outflows in star-forming sites in the Galaxy. Using the Very Large Array in its A-array configuration, we present a spectral line survey to identify methanol J={4}-1\\to {3}0E emission at 36.169 GHz. Over 900 pointings were used to cover a region 66‧ × 13‧ along the inner Galactic plane. A shallow survey of OH at 1612, 1665, 1667, and 1720 MHz was also carried out over the area covered by our methanol survey. We provide a catalog of 2240 methanol masers with narrow line-widths of ˜1 km s-1, spatial resolutions of ˜ 0\\buildrel{\\prime\\prime}\\over{.} 14× 0\\buildrel{\\prime\\prime}\\over{.} 05, and rms noises ˜20 mJy beam-1 per channel. Lower limits on the brightness temperature range from 27,000 to 10,000,000 K, showing that the emission is of non-thermal origin. We also provide a list of 23 OH (1612), 14 OH (1665), 5 OH (1667), and 5 OH (1720 MHz) masers. The origin of such a large number of methanol masers is not clear. Many methanol masers appear to be associated with infrared dark clouds, though it appears unlikely that the entire population of these masers traces the early phase of star formation in the Galactic center.

    We present position-velocity strip maps of the Galactic Center region in the CO J=7-6 and J=4-3 transitions observed with the Antarctic Submillimeter Telescope and Remote Observatory (AST/RO) located at Amundsen-Scott South Pole Station. Emission from the two rotational transitions of 12^CO was mapped at b=0 deg for 3.5 deg > l > -1.5 deg, on a 1' grid with a FWHM beamsize of 58'' at 806 GHz and 105'' at 461 GHz. Previous observations of CO J=4-3 (Martin et al., in preparation) and CI (Ojha et al. 2001) emission from this region show that these lines are distributed in a manner similar to CO J=1-0 (Stark et al. 1987); the (CO J=4-3)/(CO J=1-0) line ratio map is almost featureless across the entire Galactic Center region. In contrast, the CO J=7-6 emission from the Galactic Center is strongly peaked toward the Sgr A and Sgr B molecular complexes. A Large Velocity Gradient (LVG) analysis shows that aside from the two special regions Sgr A and Sgr B, the photon-dominated regions within a few hundred parsecs of t...

    AIM: To identify the risk factors for, and to report the microbiological findings and clinical outcomes of, severe microbial keratitis (MK). METHODS: This was a retrospective study of all cases of presumed MK admitted to a tertiary referral center over a 2-year period (September 2001 to August 2003). Data recorded included demographic data, details relating to possible risk factors, results of microbiological studies, clinical findings at presentation, and clinical and visual outcomes. RESULTS: Ninety patients were admitted with a diagnosis of presumed MK during the study period. The mean age of patients was 45 +\\/- 32 years, and the male to female ratio was 47:43 (52.2%:47.7%). Predisposing risk factors for MK included contact lens wear (37; 41.1%), anterior segment disease (19; 21.1%), ocular trauma (13; 14.4%), systemic disease (5; 5.6%), and previous ocular surgery (1; 1.1%). Cultured organisms included gram-negative bacteria (17; 51.5%), gram-positive bacteria (11, 33.3%), acanthamoeba (2; 6.1%), and fungi (1; 3%). Visual acuity improved significantly after treatment [mean best-corrected visual acuity (+\\/-standard deviation) at presentation: 0.76 (+\\/-0.11); mean best-corrected visual acuity at last follow-up: 0.24 (+\\/-0.07); P < 0.001]. Secondary surgical procedures were required in 18 (20%) cases, and these included punctal cautery (1; 1.1%), tissue glue repair of corneal perforation (2; 2.2%), tarsorrhaphy (9; 9.9%), Botulinum toxin-induced ptosis (1; 1.1%), penetrating keratoplasty (3; 3.3%), and evisceration (2; 2.2%). CONCLUSIONS: Contact lens wear remains a significant risk factor for severe MK. MK remains a threat to vision and to the eye, but the majority of cases respond to prompt and appropriate antimicrobial therapy.

    (Abridged) We present the first Laser Guide Star Adaptive Optics (LGS-AO) observations of the Galactic center. LGS-AO has dramatically improved the quality, robustness, and versatility with which high angular resolution infrared images of the Galactic center can be obtained with the W. M. Keck II 10-meter telescope. Specifically, Strehl ratios of 0.7 and 0.3 at L'[3.8 micron] and K'[2.1 micron], respectively, are achieved in these LGS-AO images. During our observations, the infrared counterpart to the central supermassive black hole, Sgr A*-IR, showed significant infrared intensity variations, with observed L' magnitudes ranging from 12.6 to 14.5 mag. The faintest end of our L' detections, 1.3 mJy (dereddened), is the lowest level of emission yet observed for this source by a factor of 3. No significant variation in the location of SgrA*-IR is detected as a function of either wavelength or intensity. Near a peak in its intensity, we obtained the first measurement of SgrA*-IR's K'-L' color (3.0 +- 0.2 mag, obs...

    Cancrum oris is a gangrenous stomatitis arising from a periodontal infection and leading to severe soft tissue and bone destruction. The pathology involves numerous factors including local thrombosis, vascularitis, necrotizing gingivitis, immunodeficiency, Gram negative and anaerobic infection. It is usually a disease of infants and malnourished children in tropical areas often occurring after a debilitating disease like measles [3]. Burkitt lymphoma is a highly aggressive non-Hodgkin lymphoma first described by Burkitt in 1958 in African children from areas holoendemic for malaria. It is the first cancer of African child [6]. The association between Burkitt lymphoma and cancrum oris is non common. We report in the present study three cases of this association at the Academic Hospital Yalgado Ouedraogo of Ouagadougou. This association poses a problem of late diagnosis with difficulties in therapeutic management.

    Full Text Available Monitoring surface water velocity during flood events is a challenging task. Techniques based on deploying instruments in the flow are often unfeasible due to high velocity and abundant sediment transport. A low-cost and versatile technology that provides continuous and automatic observations is still not available. LSPIV (large scale particle imaging velocimetry is a promising approach to tackle these issues. Such technique consists of developing surface water velocity maps analyzing video frame sequences recorded with a camera. In this technical brief, we implement a novel LSPIV experimental apparatus to observe a flood event in the Tiber river at a cross-section located in the center of Rome, Italy. We illustrate results from three tests performed during the hydrograph flood peak and recession limb for different illumination and weather conditions. The obtained surface velocity maps are compared to the rating curve velocity and to benchmark velocity values. Experimental findings confirm the potential of the proposed LSPIV implementation in aiding research in natural flow monitoring.

    2013-01-01

    We have created 0.3--10 keV, 13 year, unabsorbed luminosity lightcurves for 528 X-ray sources in the central 20' of M31. We have 174 Chandra observations spaced at ~1 month intervals thanks to our transient monitoring program, deeper observations of the M31 nucleus, and some public data from other surveys. We created 0.5--4.5 keV structure functions (SFs) for each source, for comparison with the ensemble structure function of AGN. We find 220 X-ray sources with luminosities > ~1E+35 erg/s that have SFs with significantly more variability than the ensemble AGN SF, and are likely X-ray binaries (XBs). A further 30 X-ray sources were identified as XBs using other methods. We therefore have 250 probable XBs in total, including ~200 new identifications. This result represents great progress over the ~50 XBs and ~40 XB candidates previously identified out of the ~2000 X-ray sources within the D_25 region of M31; it also demonstrates the power of SF analysis for identifying XBs in external galaxies. We also identify...

    2016-01-01

    Full Text Available Background: Patients with significant bilateral carotid artery stenosis requiring urgent cardiac surgery have an increased risk of stroke and death. The optimal management strategy remains inconclusive, and the available evidence does not support the superiority of one strategy over another. Materials and Methods: A number of noninvasive strategies have been developed for minimizing perioperative stroke including continuous real-time monitoring of cerebral oxygenation with near-infrared spectroscopy (NIRS. The number of patients presenting with this combination (bilateral significant carotid stenosis requiring urgent cardiac surgery in any single institution will be small and hence there is a lack of large randomized studies. Results: This case series describes our early experience with NIRS in a select group of patients with significant bilateral carotid stenosis undergoing urgent cardiac surgery (n = 8. In contrast to other studies, this series is a single surgeon, single center study, where the entire surgery (both distal ends and proximal ends was performed during single aortic clamp technique, which effectively removes several confounding variables. NIRS monitoring led to the early recognition of decreased cerebral oxygenation, and corrective steps (increased cardiopulmonary bypass flow, increased pCO 2 , etc., were taken. Conclusion: The study shows good clinical outcome with the use of NIRS. This is our "work in progress," and we aim to conduct a larger study.

    We report a case of a 45-year-old woman in whom an abnormality was identified by an examination when she was 42 years old. Breast ultrasonography revealed a cyst in the C area of the left breast. Ultrasonography performed 3 years later showed a mass lesion, 1 cm in diameter, in the C area of the left breast. Contrast-enhanced magnetic resonance imaging (MRI) showed a mass shadow. Core needle biopsy was performed, and the pathological diagnosis was mucinous carcinoma. Partial excision of the breast and sentinel lymph node biopsy were performed. The final histopathological diagnosis was mucinous carcinoma( pure type, estrogen receptor[ ER][ +], progesterone receptor[ PgR][ +], human epidermal growth factor receptor-2[ HER2][ 0], Ki67[ 10%], T1N0M0, stage I). One year after the operation, no signs of recurrence or metastasis have been observed. It was difficult to ascertain the presence of a lesion as the patient experienced pregnancy and childbirth during serial observations. An early diagnosis was made by imaging techniques such as consecutive ultrasonography, owing to which we were able to treat the patient early. The findings of this case emphasize the need for serial imaging studies.

    2004-01-01

    Objective: To observe the therapeutic effects of Qi Jie Granule (芪竭颗粒) on chronic pelvic inflammation. Method: The therapeutic effect, T-lymphocytic subgroups and indexes of blood rheology were observed when 102 cases of chronic pelvic inflammation in the treatment group were treated with Qi Jie Granule, and another 70 cases were treated with Qian Jin Pian as the controls. Results: The total effective rate was 96.08% in the treatment group, but 84.29% in the control group with a significant difference between the two groups (P<0.01). Qi Jie Granule was also found effective in improving blood viscosity and regulating T-lymphocytic subgroups, and the difference before and after the treatment was also very significant (P<0.05 or P<0.01). Conclusion: The nature of chronic pelvic inflammation is qi deficiency and blood stasis in accordance with the theory of traditional Chinese medicine (TCM). As a drug that is indicated for chronic pelvic inflammation, its mechanism may be related to the improved blood circulation, accelerated inflammatory absorption and regulated immune function.

    2005-05-01

    The main aim of this article is to examine and review the usage of forests for the purpose of tourism in Turkey with the case study of Antalya-Belek. The use and conversion of forest lands is central to tourism development. Land use change is responsible for the majority of the negative environmental impacts of tourism on natural resources. Worldwide, forests and coastal zones are converted for the construction of tourist facilities. The rapid emergence of mass tourism development in Turkey, encouraged without considering protection and sustainable use of natural and cultural resources, has resulted in serious problems in forest areas. This paper is particularly concerned with land use change in forests (or deforestation) created by the allocation of forest lands to build tourist facilities. In Belek, a tourism center located in Antalya province's coastal areas and the fastest growing destination of the country, all tourist facilities have been established in forest lands under the status of conservation forest. Today, the Belek Conservation Forest is under severe pressure from tourism.

    Lloyd, David; Dykes, Jason

    2011-12-01

    Working with three domain specialists we investigate human-centered approaches to geovisualization following an ISO13407 taxonomy covering context of use, requirements and early stages of design. Our case study, undertaken over three years, draws attention to repeating trends: that generic approaches fail to elicit adequate requirements for geovis application design; that the use of real data is key to understanding needs and possibilities; that trust and knowledge must be built and developed with collaborators. These processes take time but modified human-centred approaches can be effective. A scenario developed through contextual inquiry but supplemented with domain data and graphics is useful to geovis designers. Wireframe, paper and digital prototypes enable successful communication between specialist and geovis domains when incorporating real and interesting data, prompting exploratory behaviour and eliciting previously unconsidered requirements. Paper prototypes are particularly successful at eliciting suggestions, especially for novel visualization. Enabling specialists to explore their data freely with a digital prototype is as effective as using a structured task protocol and is easier to administer. Autoethnography has potential for framing the design process. We conclude that a common understanding of context of use, domain data and visualization possibilities are essential to successful geovis design and develop as this progresses. HC approaches can make a significant contribution here. However, modified approaches, applied with flexibility, are most promising. We advise early, collaborative engagement with data – through simple, transient visual artefacts supported by data sketches and existing designs – before moving to successively more sophisticated data wireframes and data prototypes.

    Full Text Available With the entrepreneurship mission incorporated into the education and research missions of universities, their role in the economic and social development in societies has increased. Thus, subjects revolving around academic entrepreneurship and knowledge commercialization have drawn the attention of many researchers and politicians in different countries in the world. In Iran, too, the knowledge commercialization phenomenon is in its prime and is in its early stages of taking shape and development. Therefore, this paper aims to identify obstacles and solutions in the commercialization of university research in Iran. The qualitative research method has been used in the form of a case study. The research data collection tools consist of semi-structured interviews. As a compliment of data collection tools, some evidence and documents were also studies. The research statistical population includes all the individuals engaged in knowledge commercialization in the University of Tehran. Twenty six interviews were conducted before data saturation reached. The results of the qualitative research indicate that the organizational, environmental/institutional and internal university research commercialization impeding factors are critical obstacles in the Small Business Development Center (SBDC of the University of Tehran and policy makers should devise proper strategies in light of these factors.

    Expanded clinical experience with patients taking antiangiogenic compounds has come with increasing recognition of the renal adverse effects. Because renal histology is rarely sought in those patients, the renal consequences are underestimated. Antiangiogenic-treated-cancer patients, who had a renal biopsy for renal adverse effects from 2006 to 2013, were included in the current study. Clinical features and renal histologic findings were reviewed. Our cohort was 100 patients (58 women) with biopsy-proven kidney disease using anti-vascular endothelial growth factor (VEGF) therapy with a mean age of 59.8 years (range, 20-85 yr). Patients were referred for proteinuria, hypertension, and/or renal insufficiency. Kidney biopsy was performed 6.87 ± 7.18 months after the beginning of treatment. Seventy-three patients experienced renal thrombotic microangiopathy (TMA) and 27 patients had variable glomerulopathies, mainly minimal change disease and/or collapsing-like focal segmental glomerulosclerosis (MCN/cFSGS). MCN/cFSGS-like lesions developed mainly with tyrosine-kinase inhibitors, whereas TMA complicated anti-VEGF ligand. Thirty-one percent of TMA patients had proteinuria up to 1 g/24 h. Half of TMA cases are exclusively renal localized. Pathologic TMA features are intraglomerular exclusively. MCN/cFSGS glomeruli displayed a high abundance of KI-67, but synaptopodin was not detected. Conversely, TMA glomeruli exhibited a normal abundance of synaptopodin-like control, whereas KI-67 was absent. Median follow-up was 12 months (range, 1-80 mo). Fifty-four patients died due to cancer progression. Hypertension and proteinuria resolved following drug discontinuation and antihypertensive agents. No patient developed severe renal failure requiring dialysis. Drug continuation or reintroduction resulted in a more severe recurrence of TMA in 3 out of 4 patients requiring maintenance of anti-VEGF agents despite renal TMA. In conclusion, TMA and MCN/cFSGS are the most

    The aim of the study was to investigate the clinical features of systemic lupus erythematous (SLE) complicated with Evans syndrome (ES). We conducted a retrospective case-control study to compare the clinical and laboratory features of age- and gender-matched lupus patients with and without ES in 1:3 ratios. In 5724 hospitalized SLE patients, we identified 27 (0.47%, 22 women and 5 men, average age 34.2 years) SLE patients complicated with ES. Fifteen patients (55.6%) presented with hematologic abnormalities initially, including 6 (22.2%) cases of isolated ITP, 4 (14.8%) cases of isolated AIHA, and 5 (18.5%) cases of classical ES. The median intervals between hematological presentations the diagnosis of SLE was 36 months (range 0-252). ES developed after the SLE diagnosis in 4 patients (14.8%), and concomitantly with SLE diagnosis in 8 patients (29.6%). Systemic involvements are frequently observed in SLE patients with ES, including fever (55.6%), serositis (51.9%), hair loss (40.7%), lupus nephritis (37%), Raynaud phenomenon (33.3%), neuropsychiatric (33.3%) and pulmonary involvement (25.9%), and photosensitivity (25.9%). The incidence of photosensitivity, hypocomplementemia, elevated serum IgG level, and lupus nephritis in patients with ES or without ES was 25.9% vs 6.2% (P = 0.007), 88.9% vs 67.1% (P = 0.029), 48.1% vs 24.4% (P = 0.021), and 37% vs 64.2% (P = 0.013), respectively. Twenty-five (92.6%) patients achieved improvement following treatment of glucocorticoids and immunosuppressants as well as splenectomy, whereas 6 patients experienced the relapse and 1 patient died from renal failure during the follow-up. ES is a relatively rare complication of SLE. Photosensitivity, hypocomplementemia, and elevated serum IgG level were frequently observed in ES patients, but lupus nephritis was less observed. More than half of patients presented with hematological manifestation at onset, and progress to typical lupus over months to years. Therefore

    Prostatic adenocarcinoma is the commonest solid malignancy seen in Omani elderly males 60-80 years of age. The Gleason grade is the most widely used grading system for prostatic carcinoma and is recommended by the World Health Organization. A peer review was carried out at the Pathology Department of Sultan Qaboos University Hospital (SQUH), Oman, to assess the quality of reporting at the center. The aim of this study was to determine inter-observer variation among 7 pathologists working at a tertiary care center in Oman. A total of 47 consecutive prostatic biopsies were interdependently reviewed by seven pathologists and the results obtained were compared with each other and the original diagnosis. This peer review indicated a fair inter-observer agreement (0.482) among 7 pathologists in the department, with fair to moderate agreement when the results were compared to the reported diagnosis, comparable to the published literature. Dual and sub-specialty reporting are being instituted to improve the performance in this vital aspect of pathology.

    Full Text Available Guillain-Barré Syndrome (GBS can be triggered by gastrointestinal or respiratory infections, including influenza. During the 2009 influenza A (H1N1 pandemic in the United States, monovalent inactivated influenza vaccine (MIV availability coincided with high rates of wildtype influenza infections. Several prior studies suggested an elevated GBS risk following MIV, but adjustment for antecedent infection was limited.We identified patients enrolled in health plans participating in the Vaccine Safety Datalink and diagnosed with GBS from July 2009 through June 2011. Medical records of GBS cases with 2009-10 MIV, 2010-11 trivalent inactivated influenza vaccine (TIV, and/or a medically-attended respiratory or gastrointestinal infection in the 1 through 141 days prior to GBS diagnosis were reviewed and classified according to Brighton Collaboration criteria for diagnostic certainty. Using a case-centered design, logistic regression models adjusted for patient-level time-varying sources of confounding, including seasonal vaccinations and infections in GBS cases and population-level controls.Eighteen confirmed GBS cases received vaccination in the 6 weeks preceding onset, among 1.27 million 2009-10 MIV recipients and 2.80 million 2010-11 TIV recipients. Forty-four confirmed GBS cases had infection in the 6 weeks preceding onset, among 3.77 million patients diagnosed with medically-attended infection. The observed-versus-expected odds that 2009-10 MIV/2010-11 TIV was received in the 6 weeks preceding GBS onset was odds ratio = 1.54, 95% confidence interval (CI, 0.59-3.99; risk difference = 0.93 per million doses, 95% CI, -0.71-5.16. The association between GBS and medically-attended infection was: odds ratio = 7.73, 95% CI, 3.60-16.61; risk difference = 11.62 per million infected patients, 95% CI, 4.49-26.94. These findings were consistent in sensitivity analyses using alternative infection definitions and risk intervals for prior

    Objective: To conduct a descriptive analysis on 31 cases of children with floating elbow who were attended at our clinic between 1994 and 2009, and to review the literature relating to this topic. Methods: Data were obtained through examining the medical records. The following variables were used: age, gender, side, mechanism, type of fracture, classification, treatment and complications. Results: Twenty-four patients (77.4%) were male and seven (22.6%) were female. The mean age was 8.5 (± 3.2) years, ranging from one to 14 years. The left side was predominantly affected (67.7%). The commonest injury mechanism was a fall from a height (74.2%). All the supracondylar fractures were Gartland type III. Distal radius fractures alone, of Salter-Harris type II, were diagnosed in 22 patients (71%). Open fractures occurred in 22 cases (71%). Closed reduction and application of a plaster cast for a closed fracture of the distal radius was performed in two patients (6.45%). Simultaneous conservative treatment for two fractures was not used. Sixteen supracondylar fractures (54.8%) were fixed using crossed wires, at 90° to each other, and in 14 cases (45.16%), an intramedullary wire was used together with another wire introduced through the lateral epicondyle at 45°. The following complications were observed: deformed consolidation (10%), nerve injuries (6%), compartment syndrome (3%) and pin path infection (16%). Conclusions: This is an uncommon injury that in most cases results from high-energy trauma. Surgical treatment for both fractures is recommended by most authors. Ulnar nerve injuries were correlated with the fixation method, but no neurological injuries were triggered by the initial trauma. PMID:27027045

    2002-10-01

    On October 21, 2002, the Minister of Foreign Affairs of the Republic of Chile, Mrs. María Soledad Alvear and the ESO Director General, Dr. Catherine Cesarsky , signed an Agreement that authorizes ESO to establish a new center for astronomical observation in Chile . This new center for astronomical observation will be for the Atacama Large Millimeter Array (ALMA) , the largest ground based astronomical project for the next decades. On this occasion, Minister Alvear stated that "we want to have ALMA working as soon as possible, which will constitute a pride not only to Chilean scientists but for the whole country and in particular, for the community of the Antofagasta Region" . ESO Director General Cesarsky said that "signing this agreement between the Government of Chile and ESO is a historical step in the astronomical collaboration between Chile and ESO and it will allow Chile to host, once again, a project of worldwide interest and impact" . ALMA is a joint project on equal basis between ESO and AUI (Associated Universities, Inc.). These organizations represent the scientific interests of Europe on one side and the United States with Canada on the other side. Chilean astronomers are closely involved with the project and 10% of the observing time will be reserved for Chilean science. ALMA will be built in the Andes, on the Plateau of Chajnantor (see the Chajnantor Photo Gallery ), 5000 metres above sea level and 60 km East of the town of San Pedro de Atacama. The array will be comprised of 64 antennas with unprecedent sensitivity and angular resolution that will allow studying the origin of galaxies, stars and planets, opening new horizons for astronomy, and being able to observe galaxies across the universe where stars are being formed. The agreement now signed between ESO and the Government of the Republic of Chile recognizes the interest that the ALMA Project has for Chile, as it will deepen and strengthen the cooperation in scientific and technological matters

    Full Text Available In this article it has been carried out an approach to resilience and affectivity as key elements to socio-educational intervention. Its theoretical and qualitative research are based on the intervention of the educator and his ability as a resilience tutor within a center for unaccompanied migrant children. From a qualitative perspective, participant observation and 9 interviews held with 3 female and 6 male educators had been used. The analysis and interpretation of the results show some evidences linked to the detection of risk factors and protection, characteristics of the educational intervention in the reception phase, and the environment as key issues in the period of representation and relation, and finally on the socio-educative bases of the resilience teaching action. Some of the conclusions take in account the results of this investigation are the following: resilience shares with education a key factor such as the importance of the quality of the human environment and the interactions manifested within this last one, and as an educational bond is created, there is a space for its own stimulation. It is also set out the necessity of continuing with the research within this field linked to the resilience and the social education.

    The second Wind Forecast Improvement Project (WFIP2) is a DOE and NOAA funded public-private partnership whose goal is to improve NWP model forecast skill for turbine-height winds in regions with complex terrain. WFIP2 partners include DOE National Laboratories (PNNL, ANL, NREL, LLNL), NOAA Laboratories (ESRL, ARL), Vaisala Inc., NCAR, the University of Notre Dame and University of Colorado, and the Bonneville Power Administration. A core element of WFIP2 is an 18 month field program located in the Pacific Northwest, focusing on the Columbia River Gorge and Basin in eastern Oregon and Washington states, with instrument deployment occurring in the summer and autumn of 2015. The approach taken is to collect an extensive set of new meteorological observations, especially within the atmospheric boundary layer, use these to observe and understand relevant atmospheric processes, develop and test new model physical parameterization schemes, and ultimately transfer these improved models to NOAA/NWS operations and to the wider meteorological community. Observing systems that will be deployed for WFIP2 include: 11 wind profiling radars 17 sodars 5 wind profiling lidars 4 scanning lidars 4 radiometers 10 microbarographs ceilometer 28 sonic anemometers Numerical models that are being used for WFIP2 are WRF-based models including the NOAA RAP (Rapid Refresh) and High Resolution Rapid Refresh (HRRR), as well as the NAM and GFS. Science issues that are being addressed include gap flow, mountain waves, mountain wakes, convective storm outflows, the mix-out of stable cold pools, and boundary layer turbulence profiling. An overview of WFIP2 will be given with an emphasis on the suite of instrumentation deployed and their observational capabilities. Several case studies of interesting meteorological events from the first several months of the field program will be presented, including comparisons with model forecasts.

    Project management education programmes are often proposed in higher education to give students competences in project planning (Gantt's chart), project organizing, human and technical resource management, quality control and also social competences (collaboration, communication), emotional ones (empathy, consideration of the other, humour, ethics), and organizational ones (leadership, political vision, and so on). This training is often given according a training-by-project type of learning with case studies. This article presents one course characterized by a pedagogical organization based upon Knowledge Management (KM) concepts: knowledge transfer and construction throughout a learning circle and social interactions. The course is supported by a rich and complex tutor organization. We have observed this course by using another KM method inspired from KADS with various return of experience formalized into cards and charts. Our intention is, according to the model of Argyris and Sch\\"on (Smith, 2001), to gai...

    Mycobacterium ulcerans infection is the third most important mycobacterial infection in the world. It has been described in many different countries including French Guiana. The diagnosis of M. ulcerans infection by culture is often difficult because culture is hard to perform in endemic areas and their sensitivity is not reliable. As a result the diagnosis of this infection is often delayed. However, molecular methods are now available to diagnose rapidly infections by M. ulcerans and distinguish it from other mycobacteria. We report three cases of skin infection due to M. ulcerans observed in French Guiana. Diagnosis was initially made by polymerase chain reaction and was confirmed later by culture (in two patients) and inoculation to mice (in one patient). A faster diagnosis of M. ulcerans infection should lead to a better prognosis of this infection.

    A great dust storm occurred in Tehran on 2 June 2014 and caused severe damage to properties and involved loss of human life. From the visual evidence available, it can be regarded as a case of haboob. As a lower latitude phenomenon, its occurrence in Tehran was unprecedented in the last 50 years. This paper aims to present a detailed analysis of the weather conditions, the pathways by which dust particles were ingested by the haboob, as well as the impact of the urban boundary layer on the intensity and propagation of the dust storm. Using numerical simulation carried out by the WRF-Chem model and various observational techniques, the coupling of a low-level small-scale deformation field with a lower-tropospheric cold pool produced by precipitating mid-tropospheric clouds is identified as the main process involved in shaping this rare dust storm.

Furthermore, several complementary medical approaches remained ineffective. In the long run, only an Iberis amara drug combination relieved pain sufficiently. The drug is registered in Germany for the indications irritable bowel syndrome and dyspepsia. The multi-target approach of this combination drug may account for the effectiveness under these fundamentally different pathophysiological conditions. No serious undesired effects have been described in the use of this drug for other indications and none were observed in this case.Keywords: Iberis amara combination, early dumping syndrome, late dumping syndrome

    Spulber, Mariana; Schlick, Shulamith

    2010-06-03

    We present electron spin resonance (ESR) experiments that describe the interaction of beta-cyclodextrin (beta-CD) with spin adducts of three spin traps: 5,5-dimethyl-1-pyrroline N-oxide (DMPO), N-tert-butyl-alpha-phenylnitrone (PBN), and 2-methyl-2-nitrosopropane (MNP). The focus was on spin adducts of oxygen-centered radicals trapped by DMPO and PBN and on carbon-centered radical adducts trapped by MNP. The radicals were generated by reaction with hydroxyl radicals and the spin adducts studied were DMPO/OH and PBN/OH, MNP/CH(2)COOH generated in CH(3)COOH, and MNP/CF(2)COOH in CF(2)HCOOH. Di-tert-butyl nitroxide ((CH(3))(3)C)(2)NO (DTBN) was also detected in experiments with MNP as the spin trap. A range of interactions of the spin adducts and DTBN with beta-CD was identified. The presence of beta-CD led to significant stabilization of DMPO/OH and PBN/OH but to a negligible effect on the (14)N hyperfine splitting of the adducts, a(N), indicating that the N-O group is outside the beta-CD cavity. An increase of a(N) was detected for DTBN and MNP/CH(2)COOH in CH(3)COOH in the presence of beta-CD, a result we assigned to bonding at the rim of the host. Experiments with methylated beta-CD (Me beta-CD) provided support for this conclusion. A different type of complexation was detected for DTBN and MNP/CF(2)COOH in CF(2)HCOOH: for specific host concentrations both "in" and "out" species were detected. We suggest that the hydrophobicity of the fluorinated adduct leads to insertion of the adduct inside the host cavity. Calculation of the association constant K(a) indicated the competition between DTBN and the adduct for inclusion in the host. For MNP as spin trap, the two nitroxide radicals (adduct and DTBN) have the same type of interaction with the host: at the rim in acetic acid, and inside the host cavity in CF(2)HCOOH. Experiments with DTBN in the absence of the spin trap and of adducts illuminated the effect of the local polarity and of the pH on the hyperfine

    Objective: To study the effect of tacrolimus (Prograf, FK506) in preventing renal allograft rejection. Methods: The curative effect, therapy index, toxicity and side effects of FK506 were observed in 294renal transplant recipients among whom 268 received FK506 24 h after the operation and the other 26 with cyclosporine (CsA) developed acute rejection after transplantation and were given FK506 to replace methylprednisolone (MP) when the latter did not result. All the patients were given oral mycophenolate mofetil (MMF, 1.0 g/d) and meticorten (Pred, 30 mg/d) 24 h later after operation. Results: In the 268 recipients previously mentioned, the incidence of acute rejection was 10. 45%, glycometabolism disorder 9.33%, nervous system disturbance 1.59%, liver function abnormality 2.99%, nephrotoxicity 1.87%, gastrointestinal disorder 17. 5%, cytomegalovirus (CMV) viremia 2.99%, and non-CMV pulmonary infection 1. 59%(4/268), with 1 fatal case for cerebral hemorrhage with normal allograft function and another 2 non-fatal cases in which function loss resulted in removal of the allografts. The blood trough concentrations of FK506were between 5 and 20μg/L. In the 26 cases of steroid-resistant rejection, 23 (88. 46%, 23/26) were reversed and the rest 3 required plasma exchange and application of OKT3 before recovery. Conclusion: As a safe and effective immunosuppressant, FK506 can reduce the incidence of allograft rejection in kidney transplant recipients with little side effects or toxicity, which is particularly applicable in patients with steroid-resistant rejection or CsA nephrotoxicity. Attention should to be paid to glycometabolism disorder due to FK506, however, the long-term effects of FK506 need further investigation.

    AIM: To analyze 67 cases of splenic abscess in a medical center of Taiwan during a period of 19 years.METHODS: From January 1986 to December 2004, a total of 67 patients with splenic abscess were enrolled for the retrospective study. The clinical characteristics,underlying diseases, organism spectra, therapeutic methods, APACHE Ⅱ scores, and mortality rates were analyzed.RESULTS: There were 41 males and 26 females with the mean age of 54.1± 14.1 years. Multiple splenic abscesses (MSA) account for 28.4% and solitary splenic abscess in 71.6% of the patients. Twenty-six of sixtyseven patients (35.8%) had extrasplenic abscesses, with leading site of liver (34.6%). Microbiological cultures were positive in 58 patients (86.6%), with 71.8% in blood culture and 93.5% in abscess culture. Gram negative bacillus (GNB) infection predominated (55.2%),with leading pathogen ofKlebsiella pneumoniae (22.4%),followed by gram positive coccus (GPC) infection (31%).Splenectomy was performed in 26 patients (38.8%),percutaneous drainage or aspiration in 21 (31.3%),and antibiotic therapy alone in 20 patients (29.9%).Eventually, 12 of 67 patients expired (17.9 %). By statistics, spleen infected with GNB was likely to develop multiple abscesses compared with infection with GPC(P=0.036). Patients with GNB infection (P= 0.009) andmultiple abscesses (P= 0.011) experienced a higher mortality rate than patients with GPC infection and solitary abscess. The mean APACHE Ⅱ score of 12 expired patients (16.3 ±3.2) was significantly higher than that of the 55 survivals (7.2 ± 3.8) (P< 0.001).CONCLUSION: MSA, GNB infection, and high APACHEⅡ scores are poor prognostic factors. Early surgical intervention should be encouraged when these risk factors are present.

    The pentalogy of Cantrell (PC) was first described in 1958. It includes five anomalies: a deficiency of the anterior diaphragm, a midline supraumbilical abdominal wall defect, a defect in the diaphragmatic pericardium, various congenital intracardiac abnormalities, and a defect of the lower sternum. Five patients showing the PC spectrum are reported. The report presents the prenatal diagnosis, the postnatal course, and the patients' outcome at a tertiary care center from June 2001 to May 2012. A literature review and the management plan for this group of patients also are discussed. All patient data were obtained via electronic medical records retrospectively after approval by the institutional review board at the home institution. The patients in the study were three males and two females. For all of the patients, a prenatal diagnosis had been determined. The mean gestational age at delivery was 36.6 weeks. One patient had associated cranial and spine malformations. All the patients had associated congenital heart disease but a normal karyotype. Four of the five patients died in the first year of life. The ages at death ranged from 0 to 259 days (mean, 46.2 ± 51.8 days). The patients who did not survive had withdrawal of care due to increased morbidity, associated complications, or parental wishes. The pentalogy of Cantrell is a wide spectrum of associations. Patients with the complete PC together with complex congenital heart disease or extracardiac malformations may have a poor prognosis. Incomplete PC cases may have a better outcome based on associated anomalies. Prenatal counseling plays a very important role in the decision-making process for the families and has a significant impact on the postnatal management. A multidisciplinary team approach is essential for successful postpartum outcomes.

    Full Text Available Rosai-Dorfman disease (RDD is a nonmalignant histiocytic disorder of unknown origin that is extremely rare. By immunohistochemistry, the RDD cells are characteristically S-100 positive and CD1a negative. Emperipolesis is a common histopathological finding, although not specific for RDD. Lymph node and cutaneous manifestations are most frequent, but diverse organs can be affected. The clinical course is unpredictable regardless of treatment. Here, we present a series of 8 cases presenting lymph node and/or cutaneous lesions. Lymph node involvement was seen in diverse regions, including mediastinal and retroperitoneal. The treatment response to steroids was diversified, and the chemotherapy response was disappointing. Associated autoimmune diseases (Sjögren syndrome and antiphospholipid syndrome were observed in 2 patients. Regardless of therapy modality, these patients exhibited a favorable prognosis in a follow-up duration that ranged from 15 to 80 months.

  17. RADIOGRAPHIC OBSERVATIONS ON THE USE OF TWO DIFFERENT REGENERATION MATERIALS IN A SINGLE SUBJECT: CASE STUDY

    Full Text Available Two infrabony defects (i.e. defects in tooth supporting bone that extend into the body of the bone in different sites in the same individual were treated surgically. Tissue regeneration was incorporated into the surgical procedures using a different material in each site (oxidized cellulose mesh and bioglass. The post surgical radiographic appearance showed increasing calcification in both sites that was not complete even at 15 months after placement. The radiographic appearance of both sites was similar but calcification was observed above the crest of alveolar bone in the oxidized cellulose mesh site that was not present with bioglass site. As calcification did not appear to be complete by 15 months after placement and it did not resemble true bone in either site it would appear that the regenerative process was not yet complete by this time. Bone regeneration may therefore progress slowly over a protracted period of time after placement. Some evidence is present that oxidized cellulose mesh may have enhanced regenerative capacity by comparison to other synthetic bone regeneration materials such as hydroxyapatite and bioglass. No conclusions could be drawn from this single case study and further work is necessary to confirm and investigate these observations more fully.

    Acne is divided into the patterns of wind and heat in the lung meridian and accumulation of dampness and heat. Forty cases of acne were treated by acupuncture plus herbal drugs (acupuncture and drug group, A) and 30 cases were treated by simple acupuncture as the control group (acupuncture group, B). The results showed basic cure in 31 cases, remarkable effect in 5 cases, effect in 3 cases, failure in 1 case and the total effective rate of 97.5% in Group A, and basic cure in 16 cases, remarkable effect in 6 cases, effect in 3 cases, failure in 5 cases and the total effective rate of 83.3% in Group B. There was no significant difference ( P > 0.05 ) in the therapeutic effect and there was a significant difference (P < 0. 01 ) in the curative rate in the two groups. The therapeutic effect was obviously better in Group A than in Group B.

    The Trifid nebula (M20) is a well-known prominent optical HII region trisected by bands of obscuring dust lanes and excited by an O7.5 star HD 164492A. Previous near-IR, mid-IR and radio continuum observations of the cluster of stars at the center of the Trifid nebula indicated circumstellar disks associated with hot stars with envelopes that are photoionized externally by the UV radiation from the hot central star, HD 164492A. Using WFPC2 of the HST, we present evidence of a resolved proplyd in H$\\alpha$ and [SII] line emission from a stellar source emitting cool dust emission. Using UKIRT, an infrared observation of the stellar source with a proplyd indicates a late F -- mid G spectral type. We also note a remarkable complex of filamentary and sheet-like structures which appear to arise from the edge of a protostellar condensation. These observations are consistent with a picture in which the bright massive star HD 164492A is responsible for the photoevaporation of protoplanetary disks of other less-massive...

    Full Text Available Residents of the rural and remote area always having limitations on accessing properly required service providers. In such condition, the establishment of rural health centers equipped with telehealth, and also the use of GIS for optimal site selection to the centers, would play an important role in facilitating the achievement of quality health services in desired time factor. This study intended to find the optimal sites for building the Rural Health Centers Equipped with remote health facilities in, Khorramabad City, using GIS. During the pilot study, we identified few effective locating criteria and sub-criteria for rural health centers equipped with telehealth, the priorities was also determined in that descriptive study. Further, we prepared a special layer for each criterion on the site selection, and by integrating such layers based on specified rules and patterns, about the spatial analysis , (like distance and density analysis were done. For such methods, we used Arc Map, Arc Catalog and Arc toolbox environments of Arc GIS (version 9.3. Finally, a map was prepared that indicated the possibility of appropriateness for establishing the centers in the study area. Considering a large number of areas, the research team selected the areas which were the appropriate location for build rural health centers which could be equipped with Telehealth.

    The objective of this study was to describe the clinical and immunological characteristics of maternal autoimmune-mediated fetal congenital heart block (CHB) in a cohort of pregnant women from an autoimmune disease pregnancy clinic. This is a retrospective observational study of all women presenting with CHB in our autoimmune disease pregnancy clinic from January 1997 to December 2014. In addition, perinatal outcome is also described. Fourteen patients accounting for 18 fetuses with CHB were identified. The median age was 32.5 years (range, 22-40). Seven (50 %) patients had Sjögren's syndrome, and the remaining seven were asymptomatic carriers of autoantibodies. All patients had anti-Ro/SSA antibodies, and 11/13 (85 %) had anti-La/SSB antibodies. The median gestational age at the time of CHB was 22 weeks (range 18-28). Complete third degree CHB was detected in 12 (67 %). Seven cases of CHB were treated with dexamethasone, two with ritodrine, and one with the association of dexamethasone, ritodrine, and terbutaline. In 9 (50 %) cases that presented with, or developed, very poor prognosis factors, such as a ventricular rate below 50-55 bpm and/or the presence of fetal hydrops, parents opted for the termination of pregnancy, after dedicated counseling. Finally, there were nine newborns (seven males [78 %]) with median age at delivery of 37 weeks (range, 32-39). A definitive epicardial pacemaker was placed in six newborns, four of them within 2 weeks of life. CHB is a severe complication related to maternal anti-Ro/SSA and anti-La/SSB antibodies. Our results confirm previous data showing that therapy is ineffective, and most of the surviving patients will require neonatal pacemaker.

    Full Text Available Abstract This report describes a case of rectal cancer with endoscopically observable white nodules caused by distal intramural lymphatic spread. A 57-year-old female presented to our hospital with frequent diarrhea and hemorrhoids. Computed tomography showed bilateral ovarian masses and three hepatic tumors diagnosed as rectal cancer metastases, and also showed multiple lymph node involvement. The patient was preoperatively diagnosed with stage IV rectal cancer. Colonoscopy demonstrated that primary rectal cancer existed 15 cm from the anal verge and that there were multiple white small nodules on the anal side of the primary tumor extending to the dentate line. Biopsies of the white spots were performed, and they were identified as adenocarcinoma. The patient underwent Hartmann’s procedure because of the locally advanced primary tumor. The white nodules were ultimately diagnosed as being caused by intramural lymphatic spreading because lymphatic permeation was strongly positive at the surrounding area. Small white nodules near a primary rectal cancer should be suspected of being intramural spreading. Endoscopic detection of white nodules may be useful for the diagnosis of distal intramural spread.

    Large and moderate tsunamis generate atmospheric internal gravity waves that are detectable using ionospheric monitoring. Indeed tsunamis of height 2cm and more in open ocean were detected with GPS (Rolland et al. 2010). We present a new method to retrieve the tsunami height from GPS-derived Total Electron Content observations. We present the case of the Mw 7.8 Haida Gwaii earthquake that occured the 28 october 2012 offshore the Queen Charlotte island near the canadian west coast. This event created a moderate tsunami of 4cm offshore the Hawaii archipelago. Equipped with more than 50 receivers it was possible to image the tsunami-induced ionospheric perturbation. First, our forward model leading to the TEC perturbation follows three steps : (1) 3D modeling of the neutral atmosphere perturbation by summation of tsunami-induced gravity waves normal modes. (2) Coupling of the neutral atmosphere perturbation with the ionosphere to retrieve the electron density perturbation. (3) Integration of the electron density perturbation along each satellite-station ray path. Then we compare this results to the data acquired by the Hawaiian GPS network. Finally, we examine the possibility to invert the TEC data in order to retrieve the tsunami height and waveform. For this we investigate the link between the height of tsunamis and the perturbed TEC in the ionosphere.

    Breast cancer is the most common type of non-skin cancer in women. 2D mammography is a screening tool to aid in the early detection of breast cancer, but has diagnostic limitations of overlapping tissues, especially in dense breasts. 3D mammography has the potential to improve detection outcomes by increasing specificity, and a new 3D screening tool with a 3D display for mammography aims to improve performance and efficiency as compared to 2D mammography. An observer study using human studies collected from was performed to compare traditional 2D mammography with this new 3D mammography technique. A prior study using a mammography phantom revealed no difference in calcification detection, but improved mass detection in 2D as compared to 3D. There was a significant decrease in reading time for masses, calcifications, and normals in 3D compared to 2D, however, as well as more favorable confidence levels in reading normal cases. Data for this current study is currently being obtained, and a full report should be available in the next few weeks.

    Full Text Available Abstract Background Epstein-Barr virus (EBV has been shown to be associated with gastric cancer. However, inconsistent findings have been reported regarding the distribution of EBV infected cells (in normal gastric epithelium vs. intestinal metaplastic cells vs. in neoplastic cells and the characteristics of EBV-associated gastric cancer. Lymph node positive EBV-associated gastric cancer has not been systematically studied. The aims of this study were to evaluate EBV-associated gastric cancer, to assess the distribution of EBV infected cells including all positive lymph nodes, and to define the characteristics of EBV-associated gastric cancer. Design The study included primary gastric cancer patients who underwent surgical resection with no preoperative treatment at M.D. Anderson Cancer Center between 1987 and 2006. Formalin-fixed paraffin-embedded tissue from these resection specimens were assessed for EBV by in situ hybridization, the gold standard for EBV detection in tissue. EBV status was analyzed along with clinicopathologic parameters including age, gender, tumor type, lymph node status, and pathologic stage of the tumor. Results Among 235 patients, 12 had intranuclear expression of EBV. EBV staining was seen only in tumor cells and no detectable EBV was observed in normal gastric mucosa, intestinal metaplasia or stromal cells. Eight of 12 patients with EBV-associated gastric cancer had regional lymph node metastasis. Of note, metastatic tumor cells in all of the involved lymph nodes of these 8 cases contained EBV. The epidemiologic data showed 11 of the 12 patients with EBV-associated gastric cancer were men, ranging in age from 54 to 78 years (mean age, 60 years; median age, 62.1 years. The age distribution for non-EBV associated gastric cancer patients ranged from 21 to 93 years (mean age, 67 years; median age, 66.4 years. Conclusion Our study demonstrated that EBV is present exclusively in gastric cancer cells. The detection of EBV in

    Several mental health public networks in Brazil focus on the participation of a plurality of actors in different collective methods of analysis and co-management of services in order to ensure improved efficiency and greater democratization of social relations. It is clear that the analysis of the effectiveness of these collectives is often done at the expense of the social relations of power they help produce. In other words, it is as if the participatory nature of the devices immediately ensure their democratic potential and their positive impact on the recovery of the users involved.Research is presented that seeks to understand the point of view of the actors involved and to determine whether or not collective spaces for the organization of mental health services contribute to the democratization of social relations that is, the construction of individual and collective capacities for debate, decision and public action. What and how people living with serious mental disorders are protagonists in the design of service and in the struggle for quality public services and how this is involved in their recovery? The research is drawn from an organizational ethnography carried out over nearly one year in Campinas, Brazil in 2012. The research focuses on a case study in a psychosocial care center (CAPS) housing for people living with serious mental disorders. To consolidate the internal validity of the case study, three collecting data techniques were applied: the shadowing over 17 institutionalize methods or devices involved in the organization of services of the CAPS, analysis of documents and forty-seven personal interviews with users, managers and workers. This article focuses on the data from the observation of one of these devices deliberation involving users, the user's assembly, as well as interviews with 15 of these participants. The results highlight how peer exchanges, emerging in the assembly of users and the convivencia space lead to collective

    We present a study of a typical explosive event (EE) at subarcsecond scale witnessed by strong non-Gaussian profiles with blue- and redshifted emission of up to 150 km s{sup –1} seen in the transition region Si IV 1402.8 Å, and the chromospheric Mg II k 2796.4 Å and C II 1334.5 Å observed by the Interface Region Imaging Spectrograph (IRIS) at unprecedented spatial and spectral resolution. For the first time an EE is found to be associated with very small-scale (∼120 km wide) plasma ejection followed by retraction in the chromosphere. These small-scale jets originate from a compact bright-point-like structure of ∼1.''5 size as seen in the IRIS 1330 Å images. SDO/AIA and SDO/HMI co-observations show that the EE lies in the footpoint of a complex loop-like brightening system. The EE is detected in the higher temperature channels of AIA 171 Å, 193 Å, and 131 Å, suggesting that it reaches a higher temperature of log T = 5.36 ± 0.06 (K). Brightenings observed in the AIA channels with durations 90-120 s are probably caused by the plasma ejections seen in the chromosphere. The wings of the C II line behave in a similar manner to the Si IV'S, indicating close formation temperatures, while the Mg II k wings show additional Doppler-shifted emission. Magnetic convergence or emergence followed by cancellation at a rate of 5 × 10{sup 14} Mx s{sup –1} is associated with the EE region. The combined changes of the locations and the flux of different magnetic patches suggest that magnetic reconnection must have taken place. Our results challenge several theories put forward in the past to explain non-Gaussian line profiles, i.e., EEs. Our case study on its own, however, cannot reject these theories; thus, further in-depth studies on the phenomena producing EEs are required.

    Full Text Available OBJECTIVES. The aim of this study was to quantify the level of health related quality of life and burnout in a call centers sample of precarious workers. METHODS. An observational study was carried out in Italy. A self-reported anonymous questionnaire was administered to temporary workers in order to estimate burn-out and quality of life levels. RESULTS. 227 questionnaires were collected. 78% of the sample was female and the mean age was 35.48 years (SD = 9.91. Among the participants, 40% were smokers, 42% regularly drinkers, 65% changed the body weight (more than 5 kg, in 1 year. The mental component score (MCS was significantly better in subject that have a regularly life style, for example in those no change their body weight (p = 0.001, sleep more than 7 hours (p = 0.018 and followed a diet (p = 0.035. The DP (depersonalization is significant higher in former smokers (p = 0.031, in underweight subjects (p = 0.025 and in the group that have a precarious employment of over 2 years (p = 0.013. CONCLUSIONS. This investigation shows that in this particular category of atypical workers depressive symptoms and quality of life were lower than the general population. It is important to underline that the interpretation of the results is limited partly by the observational character of the study.

    Jet production in PbPb collisions at a nucleon-nucleon center-of-mass energy of 2.76 TeV was studied with the CMS detector at the LHC, using a data sample corresponding to an integrated luminosity of 6.7 inverse microbarns. Jets are reconstructed using the energy deposited in the CMS calorimeters and studied as a function of collision centrality. With increasing collision centrality, a striking imbalance in dijet transverse momentum is observed, consistent with jet quenching. The observed effect extends from the lower cut-off used in this study (jet transverse momentum = 120 GeV/c) up to the statistical limit of the available data sample (jet transverse momentum approximately 210 GeV/c). Correlations of charged particle tracks with jets indicate that the momentum imbalance is accompanied by a softening of the fragmentation pattern of the second most energetic, away-side jet. The dijet momentum balance is recovered when integrating low transverse momentum particles distributed over a wide angular range relative to the direction of the away-side jet.

Assuming the $\\eta J\\psi$ signal is from a hadronic transition of the $\\psi(4040)$, the fractional transition rate is determined to be ${\\cal B}(\\psi(4040)\\to \\eta J\\psi)=(5.2\\pm 0.5\\pm 0.2\\pm 0.5)\\times 10^{-3}$, where the first, second, and third errors are statistical, systematic, and the uncertainty from the $\\psi(4040)$ resonant parameters, respectively. The production of $e^{+}e^{-} \\to \\pi^0 J\\psi$ is searched for, but no significant signal is observed, and ${\\cal B}(\\psi(4040)\\to \\pi^0 J\\psi) < 2.8 \\times 10^{-4}$ is obtained at the 90% confidence level.

    Objective: To observe the clinical therapeutic effect of acupuncture plus Chinese herbal medicines for ankylosing spondylitis (AS). Methods: A total of 80 cases of AS patients were evenly and randomly divided into treatment group and control group. In treatment group, patients were treated with acupuncture of Jiaji (夹脊EX-B 2) and oral administration of Yishen Tongdu Wan (益肾通督丸,Bolus for Reinforcing the Kidney and Dredging Governor Vessesl) and those of control group treated with oral administration of Sulfasalazin (0.5 g, twice daily). Before and after treatment, the thoracic-dilaion scale, Schober test, Bath ankylosing spondylitis disease activity index (BASDAI), Bath ankylosing spondylitis functional index (BASFI), erythrocyte sedimentation rate (ESR) and C-reaction protein (CRP) were detected separately. Results: After 6 months of treatment, of the both 40 cases in treatment and control groups, 27 (67.5%) and 13 (32.5%) were improved remarkably, 11 (27.5%) and 16 (40.0%) effective, and 2 (5.0%) and 11 (27.5%) failed, with the effective rates being 95.0% and 72.5% separately. The therapeutic effect of treatment group was significantly superior to that of control group (P<0.05). After treatment, the thoracic-dilaion scale and Schober test values increased significantly (P<0.05), while BASDAI, BASFI, ESR and CRP lowered considerably (P<0.01, P<0.05). Comparison between two groups indicated that after treatment, the decreased values of BASDAI, BASFI, ESR and CRP of treatment group were significantly lower than those of control group (P<0.01), while those of the thoracic-dilaion scale and Schober test of treatment group were significantly higher than those of control group (P<0.05, P<0.01). Results displayed that both acupuncture combined with Chinese drugs and Sulfasalazin could lower BASDAI, BASFI, ESR and CRP, raise the thoracic-dilaion scale and Schober test values considerably in AS patients, and the therapeutic effect of combined acupuncture and

    The aerosol index (AI) from the Total Ozone Mapping Spectrometer (TOMS) satellite and meteorological parameters from National Center for Environmental Prediction and the National Center for Atmospheric Research (NCEP/NCAR) reanalysis datasets were used to examine seasonal dust cases in northern Saudi Arabia. Considering all seasons, winter has the fewest dust cases, whereas summer has the most dust cases. Synoptically, surface high-pressure systems in the eastern and western regions are important for the occurrence of dust cases over the northern Arabian Peninsula. When the eastern high pressure prevails, the effects of the Indian low-pressure system on the Arabian Peninsula are weakened or become nonexistent. The extension of the western high-pressure system toward the southeast provides an opportunity for a low-pressure system over Southeast Africa to connect with the Indian low-pressure system, which increases the width of the low-pressure trough and affects the Arabian Peninsula by increasing the amount of dust over the region. At 850 hPa, the weather systems typically rotate clockwise between winter and autumn. In winter, cyclonic systems prevail in the northern region, while anticyclonic systems prevail in the south. The systems are oriented toward the northeast in spring, the west in summer, and the southeast in autumn. Moreover, northern cyclones at 500 hPa shrink as they move northward and the maximum wind speed at 250 hPa decreases from winter to summer. Furthermore, the case study confirms that a change in the relative strength of the pressure systems and a change in the orientation of the isobars (contours) affect the amount of dust over the area. When the orientation of the isobar (contour) lines become strictly north to south or east to west, the amount of dust decreases and vice versa.

    In order to establish guidelines for categorization of acute leukemia, marrow histology, special stains, and electron microscopy were performed in 100 adult leukemia cases. Differential counts for each stain were performed, and the results were combined with those obtained by electron microscopy for final classification. Myeloid (non-lymphoid) leukemia was most common (83 cases), and there were 13 lymphoid cases, two cases of erythroleukemia, and two undifferentiated leukemias. Histologic studies of marrow particles revealed significant admixtures of lymphocytes, plasma cells, and abnormal erythroid elements, particularly in acute myelomonocytic leukemia. Interpretations of cytochemical results were confirmed by ultrastructural studies in 90% of the cases. Clinically significant discrepancies between cytochemical and ultrastructural interpretations were rarely found. Only two myeloid and five lymphoid cases did not mark typically with any cytochemical stain. The single most reliable special stain was the periodic acid-Schiff stain, whereas the stain most difficult to interpret was the alpha-naphthyl acetate esterase stain. Sudan black stain was particularly helpful in demonstrating Auer rods. Five of six cases unclassified by cytochemistry were categorized by electron microscopy. Although patterns of cytochemical staining were delineated for each type of leukemia, significant intragroup variation in cytochemical reactions was recognized. This study indicates that ultrastructural examination should be routinely used for categorization of cases with equivocal cytochemical findings and for analysis of unclassified cases.

    Full Text Available Our society is on the brink of health care system reorganization and implementation of new medical technology. Hospitals have to be a core component of the medical revolution so they have to be prepared for the upcoming leap in their development. If Poland wants to be a pioneer in providing new medical solutions, the current ineffective system has to be changed. The necessary action should be taken to deal with the financial problems Polish hospitals have faced for over 20 years. The current structure of hospitals - SPZOZ, is old-fashioned and cannot adapt to a turbulent social and economic environment. The hospitals should be commercialized and restructured. Being capitalized companies will give incentives and new tools to deal with financial problems. The article presents an example of the commercialized hospital in Łańcut. We make the observations that commercialization increases: a hospital’s profitability, its employment productivity, its capital investment spending and leverage. The case proves that the transformation of hospitals to capital companies proposed by the Ministry of Health may be an appropriate approach and it does work once a reasonable management board is in charge. However, the legal structure alteration should be treated as the first step in the overall restructuring process. The article highlights the problem of managers of Polish hospitals who do not only struggle with financial shortages, but barely know which business model they should follow after commercialization to successfully run the restructuring process. Having examined the LMC the authors are crafting a prelude to the overall research on already commercialized hospitals to find an appropriate business model.

  1. Identification of the origin of chromosomal aberrations by laser microdissection: Double minutes observed in two cases derive from different chromosomes

    Single copies of tiny chromosome fragments appearing as double minutes were observed in high frequency in amniotic fluid cultures of two mothers who underwent prenatal testing because of advanced age. In case 1, the minutes were C band and NOR negative, while in case 2 they were C band positive, NOR negative. In both cases centromeric DNA sequences were detected on double minutes by fluorescence in situ hybridization (FISH) using all human centromeric probe (ONCOR). We applied the laser microdissection method to diagnose the origin of double minutes. The diagnostic procedures consisted of microdissection of double minutes from single cells, polymerase chain reaction (PCR) amplification of the dissected DNA and subsequent FISH using PCR products as a probe pool on metaphase chromosomes from the patient`s amniocytes and fibroblasts from a karyotypically normal newborn. Using this strategy we observed strong FISH signals on double minutes and centromeres of a D and G group chromosome in case 1 amniocyytes, while in case 2 the signal was present on double minutes and a C group chromosome centromere. Hybridization of amniocyte chromosome spreads with centromeric {alpha}-satellite probes for the candidate chromosomes 13/21 and 14/22 (ONCOR) in case 1 revealed FISH signals on double minutes only with the 13/21 probe. In case 2, {alpha}-satellite probes for candidate chromosomes 10 and 12 (ONCOR) were used, and only the probe for chromosome 12 hybridized to double minutes. With the laser microdissection method we were thus able to diagnose and confirm that the double minutes observed in human amniocytes derived from centromeres of chromosomes 13/21 in case 1, and from centomeres of chromosome 12 in case 2. This demonstrates the utility of laser microdissection for identification of chromosomal abnormalities of unknown origin.

    We have carried out 12CO(J =2-1) and 12CO(J =3-2) observations at spatial resolutions of 1.0-3.8 pc toward the entirety of loops 1 and 2 and part of loop 3 in the Galactic center with NANTEN2 and ASTE. These new results revealed detailed distributions of the molecular gas and the line intensity ratio of the two transitions, R3-2/2-1. In the three loops, R3-2/2-1 is in a range from 0.1 to 2.5 with a peak at ~ 0.7 while that in the disk molecular gas is in a range from 0.1 to 1.2 with a peak at 0.4. This supports that the loops are more highly excited than the disk molecular gas. An LVG analysis of three transitions, 12CO J =3-2 and 2-1 and 13CO J =2-1, toward six positions in loops 1 and 2 shows density and temperature are in a range 102.2 - 104.7 cm-3 and 15-100 K or higher, respectively. Three regions extended by 50-100 pc in the loops tend to have higher excitation conditions as characterized by R3-2/2-1 greater than 1.2. The highest ratio of 2.5 is found in the most developed foot points between loops 1 an...

    Full Text Available Introduction. Ectopic lymphoid neogenesis and the presence of IgG4-positive plasmacytes have been confirmed in chronic inflammatory sclerosing diseases. This study aims to investigate hip synovial tissues of ankylosing spondylitis (AS patients for IgG4-positive plasma cells and ectopic lymphoid tissues with germinal centers (GCs. Methods. Synovial samples were collected from 7 AS patients who received total hip replacement and were evaluated using immunohistochemistry for the presence of CD20+ B-cells, CD3+ T-cells, CD21+ follicular dendritic cells (FDC, and CD38+ plasma cells. Furthermore, immunoglobulin G (IgG and IgG4, IgA, IgM, and complement components C3d and C4d in synovia were evaluated. Both synovial CD21+ FDCs and IgG4-producing plasmacytes were analyzed. Results. All seven patients had severe fibrosis. Massive infiltrations of lymphocytes were found in 5 out of 7 patients’ synovia. Ectopic lymphoid tissues with CD21+ FDC networks and IgG4-positive plasma cells were observed coincidentally in two patients’ synovia. Conclusion. The pathophysiological mechanism of AS patients’ hip damage might be related to the coincidental presence of ectopic lymphoid tissue with FDCs network and IgG4-positive plasma cells identified here for the first time in AS patients’ inflamed synovial tissue.

    Investigating the environment of the massive black hole SgrA* at the center of the Galaxy requires the highest angular resolution available to avoid source confusion and to study the physical properties of the individual objects. GCIRS7 has been used as wavefront and astrometric reference. Our studies investigate, for the first time, its properties at 2&10um using VLTI/AMBER and MIDI. We aim at analyzing the suitability of IRS7 as an IF-phase-reference for the upcoming generation of dual-field facilities at optical interferometers. We observed with (R~30) and 50m (proj.) baseline, resulting in 9 and 45mas resolution for NIR and MIR, resp. The first K-band fringe detection of a GC star suggests that IRS7 could be marginally resolved at 2um, which would imply that the photosphere of the supergiant is enshrouded by a molecular and dusty envelope. At 10um, IRS7 is strongly resolved with a visibility of approximately 0.2. The MIR is dominated by moderately warm (200 K), extended dust, mostly distributed outsid...

    It has been hypothesized that the relatively rare autosomal dominant Alzheimer disease (ADAD) may be a useful model of the more frequent, sporadic, late-onset AD (LOAD). Individuals with ADAD have a predictable age at onset and the biomarker profile of ADAD participants in the preclinical stage may be used to predict disease progression and clinical onset. However, the extent to which the pathogenesis and neuropathology of ADAD overlaps with that of LOAD is equivocal. To address this uncertainty, two multicenter longitudinal observational studies, the Alzheimer Disease Neuroimaging Initiative (ADNI) and the Dominantly Inherited Alzheimer Network (DIAN), leveraged the expertise and resources of the existing Knight Alzheimer Disease Research Center (ADRC) at Washington University School of Medicine, St. Louis, Missouri, USA, to establish a Neuropathology Core (NPC). The ADNI/DIAN-NPC is systematically examining the brains of all participants who come to autopsy at the 59 ADNI sites in the USA and Canada and the 14 DIAN sites in the USA (eight), Australia (three), UK (one) and Germany (two). By 2014, 41 ADNI and 24 DIAN autopsies (involving nine participants and 15 family members) had been performed. The autopsy rate in the ADNI cohort in the most recent year was 93% (total since NPC inception: 70%). In summary, the ADNI/DIAN NPC has implemented a standard protocol for all sites to solicit permission for brain autopsy and to send brain tissue to the NPC for a standardized, uniform and state-of-the-art neuropathologic assessment. The benefit to ADNI and DIAN of the implementation of the NPC is very clear. The NPC provides final "gold standard" neuropathological diagnoses and data against which the antecedent observations and measurements of ADNI and DIAN can be compared.

    Full Text Available A tortuous common carotid artery poses a high risk of injury during tracheotomy. Preoperative diagnosis is therefore important to avoid serious complications. We found four cases of tortuous common carotid artery during an anatomical dissection course for students. The first case was a 91-year-old woman who had bilateral tortuous common carotid arteries without arteriosclerosis. Case 2 was a 78-year-old woman who had bilateral tortuous common carotid arteries without arteriosclerosis. Case 3 was an 86-year-old woman who died from bladder cancer and who also had a right tortuous common carotid artery without arteriosclerosis. Case 4 was an 89-year-old woman who had bilateral tortuous common carotid arteries and a tortuous brachiocephalic artery with severe arteriosclerosis. Case 4 was also examined using computed tomography to evaluate the arteriosclerosis. Computed tomography revealed severe calcification of the vascular wall, which was confirmed in the aortic arch and origins of its branches. In all four cases, the tortuosity was located below the level of the thyroid gland. Based on prior study results indicating that fusion between the carotid sheath and visceral fascia was often evident at the level of the thyroid gland, we speculated that the major region in which tortuosity occurs is at the same level or inferior to the level of the thyroid gland.

  8. Dynamics of center-periphery patterns in knowledge networks - the case of China's biotech science and technology system

    Hennemann, Stefan; Liefner, Ingo

    2011-01-01

    Science and technology systems - and their epistemic communities - are usually hierarchical and composed of a number of strong, large, leading organizations, along with a number of smaller and less influential ones. Moreover, these hierarchical patterns have a spatial structure: the leading organizations are concentrated in a few places, creating a science and technology center, whereas the majority of locations are peripheral. In the example of biotech research in China, we found dynamic changes in center-periphery patterns. These results are based on a network analysis of evolving co-authorship networks from 2001 to 2009 that were built combining national and international databases. Therefore, our results are not only relevant for evaluating the spatial structure and dynamics in the Chinese biotech system and its integration into the global knowledge network, but also revive a discussion on persistence and processes of change in the systems theory for sciencebased industries.

    1090 cases of child epilepsy were divided randomly into two groups: the treatment group (930 cases treated with anti-epilepsy capsules) and the control group (160 cases treated with luminal). The results showed that in the treatment group, 534 cases were markedly effective, 241 effective, 96 improved, 46 ineffective, and 13 aggravated, with a total effective rate of 83.33%; while in the control group, 64 cases were markedly effective, 19 effective, 38 improved, 29 ineffective, and 10 aggravated, with a total effective rate of 51.88%. The treatment group showed an obviously higher total effective rate than that in the control group (P<0.01). After treatment, cases in the two groups all had lower frequency of epilepsy attacks and shorter duration of each attack as compared with that before treatment (P<0.01), but the situation was obviously better in the treatment group. The anti-epilepsy capsules had very good effect on various types of epilepsy, especially on autonomic epilepsy and on epilepsies due to wind, phlegm, or terror as differentiated in TCM. After treatment, the recovery rate shown by EEG examination was 54.3% in the treatment group, while 38.4% in the control group, the former being obviously higher than the latter (P<0.01).

    To investigate the pregnancy outcome of the fetuses with trisomy 18, we studied 123 cases of trisomy 18 who were born at our hospital from 1993 to 2009. Among them, 95.9% were diagnosed with trisomy 18 prenatally. Prenatal ultrasound findings showed fetal growth restriction in 77.2%, polyhydramnios in 63.4% and congenital heart defects in 95.1%. For 18 cases, cesarean section (C-section) was chosen, and for 75 cases, transvaginal delivery was chosen. Premature delivery occurred in 35.5%. Stillbirths occurred in 50 cases (40.7%). Fetal demise before onset of labor occurred in 30 cases and fetal demise during labor occurred in 20 cases which was 26.7% of vaginal deliveries. Among the 73 live-born infants, the survival rate for 24 h, 1 week, 1 month and 1 year were 63%, 43%, 33% and 3%. The median survival time was 3.5 days. There was no significant difference between the survival time of C-section and that of vaginal delivery. However, for the births involving breech presentation, the survival time of C-section was significantly longer than that of vaginal delivery. When the fetus is diagnosed with trisomy 18, the parents have to make many choices. These findings constitute critical information in prenatal counseling to the couples whose fetuses have been found to have trisomy 18, especially when they choose palliative approaches in the perinatal management.

    Many healthcare organizations using Lean are becoming interested in the Patient and Family Centered Care Methodology and Practice (PFCC M/P). We suggest that integrating the two approaches can accelerate the pace of improvement and provide a powerful mechanism to keep the patient and family as the primary focus of improvement activities. We describe the two approaches and note the ways in which they are complementary. We then discuss the ways in which integrating the PFCC M/P adds value to patients, families, providers, and organizations and accelerates transformation. Finally, we suggest ways to implement PFCC M/P within Lean healthcare organizations.

    We report the histological finding of complete closure of the anterior capsulotomy window in 2 cases. The cases were successfully treated with surgery after neodymium:YAG laser anterior capsulotomy failed. Histology and immunohistochemistry were performed to determine the pathogenesis. Histology revealed the presence of elongated, fibroblast-like lens epithelial cells in association with extracellular matrix accumulation, which were positive for collagen types, fibronectin, and osteopontin. The cells were labeled with anti-alpha-smooth muscle actin antibody. The finding indicates that phenotypic modulation in lens epithelial cell to contractile cell type and accumulation of matrix are involved in closure of the anterior capsulotomy window.

    Paignon, A; Desrichard, O; Bollon, T

    2004-03-01

    This article proposes a connectionist model of the social learning theory developed by Bandura (1977). The theory posits that an individual in an interactive situation is capable of learning new behaviours merely by observing them in others. Such learning is acquired through an initial phase in which the individual memorizes what he has observed (observation phase), followed by a second phase where he puts the recorded observations to use as a guide for adjusting his own behaviour (reproduction phase). We shall refer to the two above-mentioned phases to demonstrate that it is conceivable to simulate learning by observation otherwise than through the recording of perceived information using symbolic representation. To this end we shall rely on the formalism of ecological neuron networks (Parisi, Cecconi, & Nolfi, 1990) to implement an agent provided with the major processes identified as essential to learning through observation. The connectionist model so designed shall implement an agent capable of recording perceptive information and producing motor behaviours. The learning situation we selected associates an agent demonstrating goal-achievement behaviour and an observer agent learning the same behaviour by observation. Throughout the acquisition phase, the demonstrator supervises the observer's learning process based on association between spatial information (input) and behavioural information (output). Representation thus constructed then serves as an adjustment guide during the production phase, involving production by the observer of a sequence of actions which he compares to the representation stored in distributed form as constructed through observation. An initial simulation validates model architecture by confirming the requirement for both phases identified in the literature (Bandura, 1977) to simulate learning through observation. The representation constructed over the observation phase evidences acquisition of observed behaviours, although this phase

    Case rate payments combined with utilization monitoring may have the potential to improve the quality of care by reducing over and under-treatment. Thus, a national managed care organization introduced case rate payments at one multi-site radiation oncology provider while maintaining only fee-for-service payments at others. This study examined whether the introduction of the payment method had an effect on radiation fractions administered when compared to clinical guidelines. The number of fractions of radiation therapy delivered to patients with bone metastases, breast, lung, prostate, and skin cancer was assessed for concordance with clinical guidelines. The proportion of guideline-based care ascertained from the payer's claims database was compared before (2011) and after (2013) the payment method introduction using relative risks (RR). After the introduction of case rates, there were no significant changes in guideline-based care in breast, lung, and skin cancer; however, patients with bone metastases and prostate cancer were significantly more likely to have received guideline-based care (RR = 2.0 and 1.1, respectively, pcase rate payments, while the over-treatment rate remained steady at 9%, with no significant change (p = 0.20). These findings suggest that the introduction of case rate payments did not adversely affect the rate of guideline-based care at the provider examined. Additional research is needed to isolate the effect of the payment model and assess implications in other populations.

    Aim: Ear reconstruction is a challenge for plastic and reconstructive surgeons. The ear requires sufifcient skin coverage and a three-dimensional (3D) cartilage framework. In this paper, the authors present their 10-year experience in microtia reconstruction using tissue expansion and an autogenous rib cartilage framework.Methods: Ear reconstruction was performed in 3 operative stages. During the ifrst procedure, a 50-80 mL kidney or cylinder-shaped expander was implanted deep to the subcutaneous fascia of the retroauricular mastoid region. Over a period of 3-5 months, the expander was iflled to a ifnal volume of 80-110 mL. In the next operation, the retroauricular fascia was eliminated or reserved following expander removal, and the autogenous costal cartilage framework was placed below the expanded skin lfap. At the third and ifnal stage, the earlobe transposition, tragus construction and conchal deepening were performed.Results:A total of 165 patients (166 ears) were reconstructed using tissue expansion and an autogenous rib cartilage framework. Complications included hematomas in 3 cases, expander exposure in 8 cases, cartilage exposure in 6 cases, infection and cartilage resorption in 2 cases, exposure of steel wire in 4 cases, and aseptic seroma in 2 cases. Follow-up ranging from 3 months to 5 years showed that 159 patients were satisifed with the reconstructed ear including size, location, projection, convolution, skin-colour matching, symmetry with opposite ear.Conclusion:Expansion of the retroauricular skin and fascia can provide sufifcient non-hair-bearing skin and tissue for coverage of a three-dimensional costal cartilage framework. Avoidance and prompt treatment of complications are advised in order to obtain a satisfactory reconstruction of the ear.

    Full Text Available The present paper deals with a bond graph procedure to design graphical observers for fault detection purpose. First of all, a bond Graph approach to build a graphical proportional observer is shown. The estimators’ performance for fault detection purpose is improved using a residual sensitivity analysis to actuator, structural and parametric faults. For uncertain bond graph models in linear fractional transformation LFT, the method is extended to build a graphical proportional-integralPI observer more robust to the presence of parameter uncertainties. The proposed methods allows the computing of the gain matrix graphically using causal paths and loops on the bond graph model of the system. As application, the method is used over a hydraulic system. The simulation results show the dynamic behavior of system variables and the performance of the developed graphical observers

    Full Text Available Background: Growth hormone deficiency (GHD in adults is associated with a cluster of cardiovascular risk factors that may contribute to an increased mortality for cardiovascular disease. In children, relatively few studies have investigated the effect of GHD and replacement therapy on cardiac performance and metabolic abnormalities that may place them at a higher risk of cardiovascular disease (CVD at an early age. Aim: This study was aimed to assess the left ventricular function, lipid profile, and degree of insulin resistance in Egyptian children with GHD before and after 1 year of GH replacement therapy. Settings and Design: Prospective case-control study, single-center study. Materials and Methods: Thirty children with short stature due to GHD were studied in comparison to 20 healthy age- and sex-matched children. All subjects were subjected to history, clinical examination, auxological assessment, and echocardiography to assess the left ventricular function. Blood samples were collected for measuring IGF-1, lipid profile (Total, LDL, HDL cholesterol, triglyceride, and atherogenic index (AI, fasting blood sugar, and fasting insulin levels. In addition, basal and stimulated GH levels were measured in children with suspected GHD. Statistical Analysis Used: Student′s t-test was used for parametric data, and the Mann-Whitney U-test was used for non-parametric data. Results: Total, LDL cholesterol, triglyceride, AI, and insulin were significantly higher in children with GHD than in healthy controls at baseline. After 12 months of GH replacement therapy, total, LDL cholesterol, triglyceride, AI and insulin were significantly decreased, while homeostatic model assessment for insulin resistance index (HOMA-IR was significantly increased compared to both pre-treatment and control values. At baseline, the left ventricular mass (LVM and left ventricular mass index (LVMi were significantly lower in GHD children than in controls. After 12 months of GH

    This research explores the social factors influencing hospital physicians' initial adoption of duloxetine hydrochloride, with a focus on colleague interactions. The study analyzes archival data compiled by the National Health Insurance Research Database of Taiwan to examine how the prescribing decisions made by psychiatrists' colleagues influence the likelihood of the psychiatrists' initial prescription. The results show that the adoption ratio of a physician's colleagues in a medical center is positively associated with the likelihood of a physician's adoption of the new drug. Specifically, colleague groups with similar and longer tenure as well as similar and older age have significantly positive effects. Colleague groups with the same and different gender also have positive effects. In summary, tenure and age, rather than gender, are vital sources of heterogeneous colleague interactions.

    2014-12-01

    Full Text Available Introduction: Critical thinking is rational and sound thinking that involves investigation and review of opinions followed by actions and decision-making based on reasons with accurate and rational results. In our modern, complex world, we encounter multiple changes and competition in society, especially when it comes to using the latest technology; society must progress in this trend. Medical science is not exempt in this regard, considering that critical thinking is necessary in fulfilling its goals. This research aims to investigate the physicians’ critical thinking and patient satisfaction level in the Tabriz Sina Treatment and Educational Center.Methods: This study is both descriptive and analytical, and the statistical population involves all physicians and the patients of the Tabriz Sina Treatment and Educational Center in 2013. About 30 physicians and 170 patients were selected randomly, and data were collected using the Watson and Glaser critical thinking questionnaire, as well as the Mogimi and Ramazan patient satisfaction questionnaire. The data were then analyzed by Pearson correlation and regression analysis. Results: The results showed that there was a significant and positive relationship between critical thinking and patient satisfaction in all dimensions except identification. Changes in critical thinking dimensions also changed patient satisfaction. The regression test showed that the critical thinking independent variable effect on the dependent variable was 0.558, which indicated a relatively strong correlation between these variables.Conclusion: Although the critical thinking of the physicians and medical staff is important in patient satisfaction, there is no progress towards these goals in the health system. Healthcare authorities should try to empower critical thinking in order to achieve organizational goals.

    Full Text Available Abstract Introduction Pubic osteomyelitis should be suspected in athletic individuals with sudden groin pain, painful restriction of hip movements and fever. It is an infrequent and confusing disorder, which is often heralded by atypical gait disturbance and diffuse pain in the pelvic girdle. The most common pathogen is Staphylococcus aureus but, on occasions, efforts to identify infectious agents sometimes prove negative. Pubic osteomyelitis due to Streptococcus viridans has not been reported previously in the literature. Case presentation We describe the case of a fit 24-year-old athlete, who had a wisdom tooth extracted 2 weeks prior to the presentation, which could have served as a port of entry and predisposed the patient to transient bacteraemia. Conclusion S. viridans is well known for causing infective endocarditis of native damaged heart valves, but to the best of the authors' knowledge it has not been reported previously as a cause of pubic osteomyelitis. We believe that this case should alert physicians to the association between dental procedures and osteomyelitis of the pubis secondary to S. viridans.

    Full Text Available The Council for Scientific and Industrial Research (CSIR transportable Light Detection And Ranging (LIDAR was used to collect data over Durban (29.9°S, 30.9°E during 20–23 November 2012. Aerosol measurements have been carried out in the past over Durban; however, no cloud measurements using LIDAR have ever been performed. Therefore, this study further motivates the continuation of LIDAR for atmospheric research over Durban. Low level clouds were observed on 20–22 November 2012 and high level clouds were observed on 23 November 2012. The low level cloud could be classified as stratocumulus clouds, whereas the high level clouds could be classified as cirrus clouds. Low level cloud layers showed high extinction coefficients values ranging between 0.0009 and 0.0044 m−1, whereas low extinction coefficients for high level clouds were observed at values ranging between 0.000001 and 0.000002 m−1. Optical depth showed a high variability for 20 and 21 November 2012. This indicates a change in the composition and/or thickness of the cloud. For 22 and 23 November 2012, almost similar values of optical depth were observed. Cloud-Aerosol LIDAR and Infrared Pathfinder Satellite Observations (CALIPSO revealed high level clouds while the CSIR LIDAR could not. However, the two instruments complement each other well to describe the cloudy condition.

Atmospheric suspended particles (aerosols) have significant radiative and environmental impacts, affecting human health, visibility and climate. Therefore, they are regulated by air quality standards worldwide, and monitored by regional observation networks. Satellite observations vastly improve the horizontal and temporal coverage, providing daily distributions. Aerosols are currently estimated using aerosol optical depth (AOD) retrievals, a quantitative measure of the extinction of solar radiation by aerosol scattering and absorption between the point of observation and the top of the atmosphere. Even though remarkable progresses in aerosol modeling by chemistry-transport models (CTM) and measurement experiments have been made in recent years, there is still a significant divergence between the modeled and observed results. However, AOD retrievals from satellites remains a highly challenging task mostly because it depends on a variety of different parameters such as cloud contamination, surface reflectance contributions and a priori assumptions on aerosol types, each one of them incorporating its own difficulties. Therefore, comparisons between CTM and observations are often difficult to interpret. In this presentation, we will discuss comparisons between regional modeling (CHIMERE CTM) over Mexico and satellite observations obtained by the POLDER instrument embarked on PARASOL micro-satellite. After a comparison of the model AOD with the retrieved L2 AOD, we will present an alternative

    Background: The study was to explore the causes of high inpatient expenditure through analyzing the distribution characteristics as well as the influence factors of high inpatient expenditure cases during 3 years within a Grade-A tertiary hospital through various aspects and multiple angles, thus identifying the major influence factors for high medical expenditure to develop further research. Methods: We retrospectively studied 2041 inpatient cases which cost more than RMB 100,000 Yuan per case in a Grade-A tertiary hospital from 2013 to 2015. We analyzed the compositions of the medical cost to evaluate the major factors that cause the high inpatient expenditure. All the data and materials were collected from medical record system, and the statistical methods included t-test, variance of analysis, and multivariate linear regression. Results: The average cost of the 2,041 cases was RMB 152,173 Yuan for medicines and materials of medical costs, which respectively accounted for 33.03% and 32.32% of the total cost; and the average length of hospital stay was 28.39 days/person. Diseases of skeletal and muscular system, circulatory system, and tumor were the top three disease categories of high inpatient expenditure, which accounted for 39.00%, 33.46%, and 18.03%, respectively. Complications, criticality of the disease, gender of the patients, the occurrence of death, and the excessive length of hospital stay all had great impacts on average medical expenditure, while age, hospital infection, and surgery showed no significant impact on average medical cost. Conclusions: The main factors for high inpatient expenditure included the inadequate use of high-value medicines and materials, lacking cost control measures within the hospital, the excessive length of hospital stay for inpatients, and the unnecessary treatment for the patients.

  9. REFLECTIVE PRACTICE THROUGH JOURNAL WRITING AND PEER OBSERVATION: A Case Study

    2014-10-01

    Full Text Available Journal writing and Peer Observation in an educational context have become popular techniques, with several different types of applications. They have now been used quite widely in both language teaching and in teacher training. However, despite its reported advantages in both teaching and research, there are not many Peer Observation and Diary studies available based on the writing of experienced language teachers. The Teacher participants maintain Journal writing and Peer Observation as a means of reflective practice. They consider these practices as a mirror, which reflects the teacher’s own image as a practioner. The post-reflection discussion reveals that the teacher participants believe in reflective practice as an effective means of self-evaluation and of developing sensitivity to students’ learning. This paper examines Peer Observation and journal writing of two teachers working on the same language programme in terms of a variety of topic headings, and suggests that reflective practice can be a useful tool for both classroom research and teachers’ professional development.

    Simultaneous Swift and Fermi observations of gamma-ray bursts (GRBs) offer a unique broadband view of their afterglow emission, spanning more than 10 decades in energy. We present the sample of X-ray flares observed by both Swift and Fermi during the first three years of Fermi operations. While bright in the X-ray band, X-ray flares are often undetected at lower (optical), and higher (MeV to GeV) energies. We show that this disfavors synchrotron self-Compton processes as the origin of the observed X-ray emission. We compare the broadband properties of X-ray flares with the standard late internal shock model, and find that in this scenario, X-ray flares can be produced by a late-time relativistic (gamma greater than 50) outflow at radii R approximately 10(exp 13) - 10(exp 14) cm. This conclusion holds only if the variability timescale is significantly shorter than the observed flare duration, and implies that X-ray flares can directly probe the activity of the GRB central engine.

    2016-09-01

    The current work focuses on improving volcanic ash forecasts by integrating satellite observations of ash into the Lagrangian transport and dispersion model, HYSPLIT. The accuracy of HYSPLIT output is dependent on the accuracy of the initialization: the initial position, size distribution, and amount of ash as a function of time. Satellite observations from passive infrared, IR, sensors are used both to construct the initialization term and for verification. Space-based lidar observations are used for further verification. We compare model output produced using different initializations for the 2008 eruption of Kasatochi in the Aleutian Islands. Simple source terms, such as a uniform vertical line or cylindrical source above the vent, are compared to initializations derived from satellite measurements of position, mass loading, effective radius, and height of the downwind ash cloud. Using satellite measurements of column mass loading of ash to constrain the source term produces better long-term predictions than using an empirical equation relating mass eruption rate and plume height above the vent. Even though some quantities, such as the cloud thickness, must be estimated, initializations which release particles at the position of the observed ash cloud produce model output which is comparable to or better than the model output produced with source terms located above and around the vent. Space-based lidar data, passive IR retrievals of ash cloud top height, and model output agree well with each other, and all suggest that the Kasatochi ash cloud evolved into a complex three-dimensional structure.

    The possible short gamma-ray burst (GRB) observed by {\\it Fermi}/GBM in coincidence with the first gravitational wave (GW) detection, offers new ways to test GRB prompt emission models. Gravitational wave observations provide previously unaccessible physical parameters for the black hole central engine such as its horizon radius and rotation parameter. Using a minimum jet launching radius from the Advanced LIGO measurement of GW~150914, we calculate photospheric and internal shock models and find that they are marginally inconsistent with the GBM data, but cannot be definitely ruled out. Dissipative photosphere models, however have no problem explaining the observations. Based on the peak energy and the observed flux, we find that the external shock model gives a natural explanation, suggesting a low interstellar density ($\\sim 10^{-3}$ cm$^{-3}$) and a high Lorentz factor ($\\sim 2000$). We only speculate on the exact nature of the system producing the gamma-rays, and study the parameter space of a generic Bl...

    The issue of seat belt use in middle- and low-income countries is strongly evident and has as a result higher rates of fatalities and seriously injured on the roads. The first systematic field research of the seat belt use while driving was carried out in Bosnia and Herzegovina, in 2011-2012. Research methodology consisted of two mutually conditioned parts (observation and self-reported behavior). Specific features of the methodology used are in the relationship between the observed and interviewed drivers which enabled the analysis of their observed and self-reported behavior while driving. The logistic regression method was used in this work to make the analysis of the influence of personal human characteristics (gender, age, education, exposure) and vehicles' characteristics (age) on the observed and self-reported driving behavior, from the point of view of seat belt use while driving. The influence of the listed factors on driving behavior, depending on road type (urban or rural), was given special attention in the analysis. The paper shows that certain factors do not have the same impact on driving behavior, in various conditions. Based on results from this study, it will be possible to define certain critical groups of road users and the way in which they must be addressed in order to increase the seat belt wearing rate.

    Objective. To compare peer teaching in a medical and a pharmacy clinical teaching unit and to provide suggestions for future research in pharmacy near-peer teaching. Methods. This exploratory observational study used principles of ethnographic methodology for data collection and analysis. Observations were collected in a large downtown teaching hospital. An average of 4-6 hours per day were spent observing a team of medical trainees from the Faculty (School) of Medicine in the general internal medicine (unit for two weeks, followed by a team of pharmacy trainees in an ambulatory hemodialysis (HD) unit for two weeks. Data was collected through field notes and informal interviews that were audiotaped and subsequently transcribed. Data was interpreted by the observer and reviewed weekly by two impartial pharmacists. Results. Five major themes emerged: (1) influence of peer teaching hierarchy; (2) educational distance between peer learners and teachers; (3) effect of the clinical teaching unit size on peer learning; (4) trainees’ perception of their teaching role in the clinical teaching unit; and (5) influence of daily schedule and workload on peer teaching. As opposed to pharmacy, a hierarchy and pyramidal structure of peer teaching was observed in medical experiential training. There appeared to be no effect of educational distance on near peer teaching; however, perception of teaching role and influence of daily schedule affected near-peer teaching. Conclusion. Through initial comparisons of medical and pharmacy clinical teaching units, this study provides a reflection of elements that may be necessary to successfully implement near-peer teaching in pharmacy experiential training. Future studies in this area should assess learning outcomes and participant satisfaction, preceptor workload, and impact on patient care. PMID:27756922

    @@ Auditory hallucinosis, a kind of hallucinations in sensory disturbance, is very common in psychopathic clinic. Patients with this disorder could hear sounds of different variety or nature in the absence of any appropriate external stimulus. It is especially true in patients with schizophrenia, organic psychonosema,and alcoholic psychonosema. At present, the neuroleptic agents are often used to relieve auditory hallucinosis during treatment of the mental disease,and there is not a therapy that is effective in treating auditory hallucinosis. With electro-acupuncture, the authors have treated 30 cases of auditory hallucinosis with satisfactory results. A report follows.

    Background Numerous studies have developed a "severity score" or "risk index" for short-term mortality associated with coronary artery bypass grafting (CABG). Due to the different distribution of disease types, the number of valve surgeries in the US and Europe is relatively small. Thus, a risk-scoring system for valve surgeries was developed later and used less than that for the CABG surgery. We retrospectively reviewed 5128 cases of heart valve replacement, to quantitatively assess the risk factors for hospital mortality, and establish risk models for the hospital mortality of cardiac valve replacement patients.Methods A total of 1549 cases of aortic valve replacement, 2460 cases of mitral valve replacement, and 1119 cases of combined aortic valve and mitral valve replacement that were recorded from January 2005 to December 2009 in the cardiac surgery database at Beijing Anzhen Hospital were selected for this study. The cases were randomly assigned to a indicators were selected as possible influencing factors for hospital mortality. Single-factor analysis was performed to screen these factors, and then multi-factor analysis was used to determine the risk factors for hospital mortality in the three surgeries and to establish risk models.Results In the multi-factor analysis, age, body surface area, etiology, cardiopulmonary bypass time, preoperative cardiothoracic ratio, cardiac functional classification, and preoperative creatinine were risk factors for aortic valve replacement. Etiology, preoperative history of heart failure, cardiopulmonary bypass time, preoperative cardiothoracic ratio, and preoperative left ventricular end systolic diameter were risk factors for mitral valve replacement. Age, body mass index, cardiopulmonary bypass time, and cardiac function classification were risk factors for combined aortic valve and mitral valve replacement. The risk models showed good predictive ability (Hosmer-Lemeshow test: P=0.981 in the model for aortic valve

    Intracranial mesenchymal chondrosarcoma is very rare, only 14 cases being reported in Europe and in the United States of America. Recently we experienced a case in which the follow-up indicating computed tomograms (CT) demonstrated interesting data on the radiosensitivity of this tumor. The patient, a 14-year-old female was admitted to our hospital with the complaint of left hemiplegia which had gradually progressed. CT revealed an area spreading upward from the right median base of the skull and consisted of two components showing (A) a density as high as that of calcium and (B) a density higher than that of surrounding brain tissue, but much lower than that of calcium. Temporoparietal craniotomy was performed to resect approximately one-half of the tumor. Histological finding revealed mesenchymal chondrosarcoma. The component-A was though to be a cartilaginous tissue, and-B to be an undifferentiated mesenchymal tissue. Postoperative irradiation of 7,000 rad was initiated. The effect of radiotherapy as seen on computed tomograms is as follows, (1) decrease in the volume of the tumor by 26%, (2) decrease in density and enhancement of the area which is considered to be the undifferentiated mesenchymal cells, (3) mild reduction of the area which is considered to be the caltilaginous tissue, and (4) a very high density of the entire tumor similar in degree to that of the bone one year later. These results suggested that radiotherapy is effective for this tumor.

    Objective: To compare the therapeutic effect of abdominal acupuncture plus body acupuncture and simple body acupuncture in treatment of scapulohumeral periarthritis. Methods: 68 cases of scapulohumeral periarthritis patients were randomly divided into abdominal acupuncture plus body acupuncture (AABA) group (n= 36) and simple body acupuncture (BA) group (n=32). In AABA group, abdominal acupuncture points used were Zhongwan(CV 12), Shangqu (KI 17) (on the healthy side) and Huaroumen-sanjiao (on the affected side); and body acupoints employed were Jianyu (LI 15), Jianliao(TE 14), Binao (LI 14), Quchi (LI 11), Waiguan (TE 5) and Hegu (LI 4) on the affected side. In BA group, the body acupoints used were the same to those mentioned above. The acupuncture needles were retained for 20 min. Acupuncture treatment was given once daily, with 10 sessions being a therapeutic course and the interval between two courses being one week. 2 courses of treatment were conducted altogether. Results: Following 2 courses of treatment, in AABA and BA groups, 6 (16.7%) and 1 (3.1%) cases were cured, 19 (52.8%) and 12 (37.5%) had remarkable improvement, 11 (30.6%) and 17 (53.1%) had improvement, 0 and 2 (6.25%) had no effect respectively. There was a significant difference between two groups in the therapeutic effect (P<0.05) .Conclusion: The therapeutic effect of abdominal acupuncture plus body acupuncture is superior to that of simple body acupuncture in treatment of scapulohumeral periarthritis.

    This paper provides an overview of Systems Engineering as it is applied in a conceptual design space systems department at the National Aeronautics and Space Administration (NASA) Marshall Spaceflight Center (MSFC) Advanced Concepts Office (ACO). Engineering work performed in the NASA MFSC's ACO is targeted toward the Exploratory Research and Concepts Development life cycle stages, as defined in the International Council on Systems Engineering (INCOSE) System Engineering Handbook. This paper addresses three ACO Systems Engineering tools that correspond to three INCOSE Technical Processes: Stakeholder Requirements Definition, Requirements Analysis, and Integration, as well as one Project Process Risk Management. These processes are used to facilitate, streamline, and manage systems engineering processes tailored for the earliest two life cycle stages, which is the environment in which ACO engineers work. The role of systems engineers and systems engineering as performed in ACO is explored in this paper. The need for tailoring Systems Engineering processes, tools, and products in the ever-changing engineering services ACO provides to its customers is addressed.

    The study of neighborhood characteristics and their effects on individuals has become an area of increasing attention by scholars from various disciplines in developed countries. Although there are various methods to study neighborhoods and their impact on human populations, one of the most used is the Systematic Social Observation -Observación Sistemática de Vecindarios (OSV), in Spanish-because it allows the collection of information about various features of the physical, social, environmental and economic characteristics of neighborhoods. The purpose of this article is to (i) briefly present some research on neighborhood effects influential in the U.S., ii) describe how they Systematic Social Observation was designed and implemented in the city of Santiago, Chile, iii) discuss some facilitators and obstacles of the implementation process and, finally iv) list possible contributions and limitations this approach would offer the profession of social work in Chile.

    Full Text Available When processing satellite altimetry data for Mean Sea Surface (MSS modelling in coastal environments many problems arise. The degradation of the accuracy of the Sea Surface Height (SSH observations close to the coastline and the usually irregular pattern and variability of the sea surface topography are the two dominant factors which have to be addressed. In the present paper, we study the statistical behavior of the SSH observations in relation to the range from the coastline for many satellite altimetry missions and we make an effort to minimize the effects of the ocean variability. Based on the above concepts we present a process strategy for the homogenization of multi satellite altimetry data that takes advantage ofweighted SSH observations and applies high degree polynomials for the adjustment and their uniffcation at a common epoch. At each step we present the contribution of each concept to MSS modelling and then we develop a MSS, a marine geoid model and a grid of gravity Free Air Anomalies (FAA for the area under study. Finally, we evaluate the accuracy of the resulting models by comparisons to state of the art global models and other available data such as GPS/leveling points, marine GPS SSH’s and marine gravity FAA’s, in order to investigate any progress achieved by the presented strategy

    We present observations of a new phenomenon in pulsating white dwarf stars: large-amplitude outbursts at timescales much longer than the pulsation periods. The cool (Teff = 11,010 K), hydrogen-atmosphere pulsating white dwarf PG 1149+057 was observed nearly continuously for more than 78.8 d by the extended Kepler mission in K2 Campaign 1. The target showed 10 outburst events, recurring roughly every 8 d and lasting roughly 15 hr, with maximum flux excursions up to 45% in the Kepler bandpass. We demonstrate that the outbursts affect the pulsations and therefore must come from the white dwarf. Additionally, we argue that these events are not magnetic reconnection flares, and are most likely connected to the stellar pulsations and the relatively deep surface convection zone. PG 1149+057 is now the second cool pulsating white dwarf to show this outburst phenomenon, after the first variable white dwarf observed in the Kepler mission, KIC 4552982.

    We have developed a tool for measuring the evolutional stage of the space weather regional warning centers using the approach of the innovative evolution starting from the perspective presented by Figueiredo (2009, Innovation Management: Concepts, metrics and experiences of companies in Brazil. Publisher LTC, Rio de Janeiro - RJ). It is based on measuring the stock of technological skills needed to perform a certain task that is (or should) be part of the scope of a space weather center. It also addresses the technological capacity for innovation considering the accumulation of technological and learning capabilities, instead of the usual international indices like number of registered patents. Based on this definition, we have developed a model for measuring the capabilities of the Brazilian Study and Monitoring Program Space Weather (Embrace), a program of the National Institute for Space Research (INPE), which has gone through three national stages of development and an international validation step. This program was created in 2007 encompassing competence from five divisions of INPE in order to carry out the data collection and maintenance of the observing system in space weather; to model processes of the Sun-Earth system; to provide real-time information and to forecast space weather; and provide diagnostic their effects on different technological systems. In the present work, we considered the issues related to the innovation of micro-processes inherent to the nature of the Embrace program, not the macro-economic processes, despite recognizing the importance of these. During the development phase, the model was submitted to five scientists/managers from five different countries member of the International Space Environment Service (ISES) who presented their evaluations, concerns and suggestions. It was applied to the Embrace program through an interview form developed to be answered by professional members of regional warning centers. Based on the returning

    As the number of refugees rises, medical care for refugees, asylum seekers and people with unclear residence status becomes a priority task for our health system. While access to health care is restricted for these groups of people in many German states, Hamburg provides unrestricted access to healthcare for refugees by handing out health insurance cards on arrival. Daily practice shows, however, that adequate medical care is still not always easy to achieve. In this case series we demonstrate that barriers to health care still exist on many levels. We discuss these barriers and further propose strategies to improve and to secure access to adequate health care.

    Full Text Available Service quality plays an important role in health care systems since hospitals are responsible for people's lives. This study presents an effective approach for evaluating and comparing service qualities of four hospitals. Service quality consists of different attributes and many of them are intangible and difficult to measure. Therefore, we propose a fuzzy method to resolve the ambiguity of the concepts, which are associated with human judgments. SERVQUAL model is used to evaluate the respondents' judgments of service quality and multi attribute decision making approach is implemented for the comparison among hospitals. The paper use analytical hierarchy process (AHP for obtaining criteria weight and TOPSIS for ranking the cases.

    A 74-year-old man was hospitalized due to hematemesis. Upper gastrointestinal endoscopy revealed a very large and dark red mass in the cardiac region of the stomach that extended from the upper esophagus. A biopsy specimen showed hemorrhagic tissue and no malignant cells. The tumor-like region ulcerated at 5 days after the administration of intravenous lansoprazole at a dose of 30 mg twice a day and resolved with scar formation at 2 months after a change to oral rabeprazole at a dose of 10 mg/day.We diagnosed the patient with gastroesophageal submucosal hematoma. Gastroesophageal submucosal hematoma is a rare complication. In this case, we could follow the process of its disappearance by endoscopy.

    Full Text Available Purpose: Focal nodular hyperplasia (FNH, a benign hepatic tumor with ill-defined etiology, has been increasingly reported in children treated for extra-hepatic malignancies. Serial imaging or biopsy may be needed when survivors present with liver lesions. This study aims to review the literature, compare them with our institution’s cohort and propose a less invasive diagnostic imaging modality for FNH utilizing Magnetic resonance imaging (MRI with gadoxetate disodium. Methods: We reviewed 13 case reports/series published over the last 20 years and compared them to our retrospective review of 16 childhood cancer survivors (CCS found to have liver lesions on various imaging studies. Several patients underwent biopsy for diagnosis. Results: No specific generalizations could be made in terms of which specific chemotherapeutic agents cause FNH. Seven out of 11 patients underwent radiotherapy and/or hematopoietic stem cell transplant. Additionally, 36% (4/11 had been treated for neuroblastoma. From the literature review, the use of MRI with gadoxetate disodium was difficult to evaluate. Imaging was mainly accomplished using ultrasound, computerized tomography and MRI with gadolinium. The results were often indeterminate and resulted in biopsy in 6 cases in our institution. In contrast, 5 patients underwent initial MRI with gadoxetate disodium, which confirmed the diagnosis of FNH. Conclusion: CCS have an increased risk of developing liver lesions. Consistent with previously published literature, patients exposed to radiotherapy or cytoreductive agents used for hematopoietic stem cell transplants appeared to be at higher risk. A significant proportion (36%, 4/11 of our patients with FNH was previously treated for neuroblastoma. With the introduction of MRI with gadoxetate disodium, imaging may be a viable alternative to biopsy.

    Aim. Large food bits can get stuck in the esophagus and must be removed by endoscopy. In some cases, this can be difficult or unsafe. We describe a new and safe treatment for such patients. Materials and Methods. 100 consecutive patients were referred to Akershus University Hospital with impacted food in the esophagus. In 36 patients (36%), the food passed spontaneously. In 59 (92%) of the remaining 64 patients, the food was removed by endoscopic intervention. In the last five patients, endoscopic removal was judged difficult or unsafe. These patients received the new treatment: one capsule Creon 10000 IU dissolved in 30 mL of Coca-Cola administered by a nasooesophageal tube four times daily for 2-3 days. Results. Of the 59 patients treated with endoscopic procedure, complications occurred in four (7%): three bleedings and one perforation of the esophagus. In five patients treated with Coca-Cola and Creon, the food had either passed or was soft after 2-3 days and could easily be removed. Conclusion. The treatment of choice of impacted food in the esophagus is endoscopic removal. In cases where this is difficult, we recommend treatment with Coca-Cola and Creon for 2-3 days before complications occur.

    Noma (Cancrum oris) is a gangrenous stomatitis arising from a periodontal infection and leading to severe soft tissue and bone destruction. The pathology involves numerous factors including local thrombosis, vascularitis, necrotizing gingivitis, immunodeficiency, gram negative and anaerobic infection. It is usually a disease of infants and malnourished children in tropical areas often occurring after a debilitating disease like measles. Recently, cases have been reported in adults especially elderly patients or during immunodeficiency states. Reconstructive surgery is often necessary to deal with destruction and sequel but is rarely accessible in developing countries. We report one case of noma (cancrum oris) in an HIV seropositive patient at the National Hospital in Bobo-Dioulasso. The noma was inaugural of AIDS in a 40 years old labourer coming back from Ivory Coast and no major opportunistic infection was associated. The course was fulminant leading to extensive facial gangrene with recurrent bacterial infections. The disease was fatal in this depressive, malnourished and diarrhoeic patient despite local surgical treatment, prolonged antibiotherapy and supportive care. Pathogenic mechanisms, management and preventive issues are discussed.

    Full Text Available Introduction: Public healthcare system in India suffers from poor performance mainly due to the severe shortage and high absenteeism of healthcare providers. The performance is further affected due to low productivity and competencies of the already existing healthcare providers. While management training (with a special focus on human resource issues to address the shortage to healthcare providers has gained some importance in recent past, there has been a very limited focus on how to use the exiting workforce effectively. With this backdrop, training health providers in issues pertaining to team effectiveness becomes very crucial. The case study discusses some of the dimensions of team building, as well as processes involved in performance improvement including problem identification, prioritization, and problem-solving process as demonstrated by health system improvement teams (HSIT′s. Materials and Methods: HSIT′s have been constituted and are functional at 238 secondary level facilities in Rajasthani. The case writer interacted with five HSIT′s from two districts in Rajasthan. We were able to speak to about four to five members from each team for all the five facilities. The information for the case was gathered in two ways. The first was use of an instrument on team building that was given to each member of the team to gauge their individual perception about various team building aspects. The second was with the help of group discussions that were done with all the team members for each all the five teams. All those who were present and willing to be part of the discussion were given instruments and were included in group discussions. As this was an exploratory case study, the sample size was small and, therefore, the findings from group discussion and instruments have been presented together without any quantification of the data. Results: The findings of the case study indicate moderate team empowerment. While HSIT′s were clear

    The most common form of Myasthenia gravis (MG) is due to anti-acetylcholine receptor (AChR) antibodies and is frequently associated with thymic pathology. In this review, we discuss the immunopathological characteristics and molecular mechanisms of thymic follicular hyperplasia, the effects of corticosteroids on this thymic pathology, and the role of thymic epithelial cells (TEC), a key player in the inflammatory thymic mechanisms. This review is based not only on the literature data but also on thymic transcriptome results and analyses of pathological and immunological correlations in a vast cohort of 1035 MG patients without thymoma. We show that among patients presenting a thymic hyperplasia with germinal centers (GC), 80 % are females, indicating that thymic follicular hyperplasia is mainly a disease of women. The presence of anti-AChR antibodies is correlated with the degree of follicular hyperplasia, suggesting that the thymus is a source of anti-AChR antibodies. The degree of hyperplasia is not dependent upon the time from the onset, implying that either the antigen is chronically expressed and/or that the mechanisms of the resolution of the GC are not efficiently controlled. Glucocorticoids, a conventional therapy in MG, induce a significant reduction in the GC number, together with changes in the expression of chemokines and angiogenesis. These changes are likely related to the acetylation molecular process, overrepresented in corticosteroid-treated patients, and essential for gene regulation. Altogether, based on the pathological and molecular thymic abnormalities found in MG patients, this review provides some explanations for the benefit of thymectomy in early-onset MG patients.

    Full Text Available Abstract Background We address the goal of curating observations from published experiments in a generalizable form; reasoning over these observations to generate interpretations and then querying this interpreted knowledge to supply the supporting evidence. We present web-application software as part of the 'BioScholar' project (R01-GM083871 that fully instantiates this process for a well-defined domain: using tract-tracing experiments to study the neural connectivity of the rat brain. Results The main contribution of this work is to provide the first instantiation of a knowledge representation for experimental observations called 'Knowledge Engineering from Experimental Design' (KEfED based on experimental variables and their interdependencies. The software has three parts: (a the KEfED model editor - a design editor for creating KEfED models by drawing a flow diagram of an experimental protocol; (b the KEfED data interface - a spreadsheet-like tool that permits users to enter experimental data pertaining to a specific model; (c a 'neural connection matrix' interface that presents neural connectivity as a table of ordinal connection strengths representing the interpretations of tract-tracing data. This tool also allows the user to view experimental evidence pertaining to a specific connection. BioScholar is built in Flex 3.5. It uses Persevere (a noSQL database as a flexible data store and PowerLoom® (a mature First Order Logic reasoning system to execute queries using spatial reasoning over the BAMS neuroanatomical ontology. Conclusions We first introduce the KEfED approach as a general approach and describe its possible role as a way of introducing structured reasoning into models of argumentation within new models of scientific publication. We then describe the design and implementation of our example application: the BioScholar software. This is presented as a possible biocuration interface and supplementary reasoning toolkit for a larger

    Background: In patients with nonvalvular atrial fibrillation (NVAF), embolic stroke is thought to be associated with left atrial appendage (LAA) thrombi. The WATCHMAN LAA Occlusion Device has been shown to be noninferior to conventional oral anticoagulation with warfarin for stroke prevention in patients with NVAF. This study aimed to evaluate the procedural feasibility, safety and 12-month outcomes of the WATCHMAN LAA Occlusion Device in NVAF patients with high risk for stroke in China. Methods: The clinical data of 106 NVAF patients, who were consecutively underwent LAA closure with the WATCHMAN Device between April 2014 and May 2015, were collected. Patients were followed up at 1, 3, 6, and 12 months after discharge. A transesophageal echocardiograph was performed at 45 days after implantation and repeated in case of an unexpected event during the follow-up period. Results: This study included 106 NVAF patients with a mean age of 64.2 ± 8.6 years (ranging from 50 to 88 years), and the mean CHA2DS2-VASc score of all patients was 3.6 ± 1.6 (ranging from 2 to 9). Among those 106 NVAF patients, 100 (94.3%) patients were implanted with the device successfully. The procedural success rate was 94.3% (100/106), and the occlusion rate was 100.0% (100/100). There were one tamponade, one ischemic stroke, and eight minor pericardial effusions during hospitalization. During 12-month follow-up period, two patients developed a thrombus layer on the device that resolved with additional anticoagulation: one with visible device-thrombus experienced transient ischemic stroke, and one had a hemorrhagic stroke. There were no deaths in this study. The overall survival rate was 100.0%, and nonmajor adverse event rate was 95.0% (95/100). In this study, the expected annual rate of ischemic stroke risk in these patients according to the CHA2DS2-VASc score was 4.0%, while the observed ischemic stroke rate was 2.0% per year. Conclusions: LAA closure with the WATCHMAN Device was feasible

    Full Text Available A focus of the Arctic Research of the Composition of the Troposphere from Aircraft and Satellites (ARCTAS mission was examination of bromine photochemistry in the spring time high latitude troposphere based on aircraft and satellite measurements of bromine oxide (BrO and related species. The NASA DC-8 aircraft utilized a chemical ionization mass spectrometer (CIMS to measure BrO and a mist chamber (MC to measure soluble bromide. We have determined that the MC detection efficiency to molecular bromine (Br2, hypobromous acid (HOBr, bromine oxide (BrO, and hydrogen bromide (HBr as soluble bromide (Br was 0.9±0.1, 1.06+0.30/−0.35, 0.4±0.1, and 0.95±0.1, respectively. These efficiency factors were used to estimate soluble bromide levels along the DC-8 flight track of 17 April 2008 from photochemical calculations constrained to in situ BrO measured by CIMS. During this flight, the highest levels of soluble bromide and BrO were observed and atmospheric conditions were ideal for the space-borne observation of BrO. The good agreement (R2 = 0.76; slope = 0.95; intercept = −3.4 pmol mol−1 between modeled and observed soluble bromide, when BrO was above detection limit (>2 pmol mol−1 under unpolluted conditions (NO<10 pmol mol−1, indicates that the CIMS BrO measurements were consistent with the MC soluble bromide and that a well characterized MC can be used to derive mixing ratios of some reactive bromine compounds. Tropospheric BrO vertical column densities (BrOVCD derived from CIMS BrO observations compare well with BrOTROPVCD from OMI on 17 April 2008.

    We report on the implantation of boron in individual, electrically contacted germanium nanowires with varying diameter and present a technique that monitors the electrical properties of a single device during implantation of ions. This method gives improved access to study the dynamic annealing ability of the nanowire at room temperature promoted by its quasi-one-dimensional confinement. Based on electrical data, we find that the dopant activation efficiency is nontrivially diameter dependent. As the diameter decreases, a transition from a pronounced dynamic-annealing to a radiation-damage dominated regime is observed.

    The all-sky camera data obtained in Barentsburg (Spitsbergen Archipelago) are compared with specific features of electron and ion precipitations on the DMSP F18 satellite during its flight within the camera field of view on December 15, 2012. Before arriving at the cusp from the mantle side, the satellite detects two outbursts of precipitating particles. The burst of mantle precipitations far from the cusp is observed simultaneously in both ionic and electronic components. In the ionosphere related to the satellite, no auroras are detected, which is likely due to the low intensity of the flux of precipitating electrons and their low energy (80 eV). Near the cusp, a more intensive burst of precipitations of higher-energy electrons (140 eV) is accompanied by an almost complete "locking" of ions. This burst of mantle precipitations is related to the faint luminous structure in the ionosphere. The ion locking is indicative of the accelerating potential difference in the force tube, which is based on the glowing region. The luminous structure is an element of the so-called "polewar moving auroral forms," which is related in the literature to the reconnection in the daytime magnetopause. The possible relation of the observed phenomena to the reconnected magnetic force tubes, which drift from the cusp in the antisolar direction, is also confirmed by the dispersion of ionic precipitations, i.e., an increase in ion energy as the satellite approaches to the cusp.

    We present the results of a search for dwarf novae (DNe) in globular clusters (GCs). It is based on the largest available homogeneous sample of observations, in terms of the time span, number of observations and number of clusters. It includes 16 Galactic GCs and yielded two new certain DNe: M55-CV1 and M22-CV2. All previously known systems located in our fields were recovered, too. We surveyed M4, M5, M10, M12, M22, M30, M55, NGC 288, NGC 362, NGC 2808, NGC 3201, NGC 4372, NGC 6362, NGC 6752, omega Cen (NGC 5139) and 47 Tuc (NGC 104). The discovery of two DNe, namely M55-CV1 and M22-CV2, was already reported by Kaluzny et al. (2005) and Pietrukowicz et al. (2005), respectively. In the remaining 14 GCs we found no certain new DNe. Our result raises the total number of known DNe in the Galactic globular clusters to 12 DNe, distributed among 7 clusters. Our survey recovered all three already known erupting cataclysmic variables (CVs) located in our fields, namely M5-V101, M22-CV1, and V4 in the foreground of M3...

    An intense activity of ripples during the nighttime was observed in airglow images over São João do Cariri (36.5° W, 7.4° S) on 10 October 2004 which lasted for two hours. Those ripples appeared simultaneously with the crossing of a mesospheric front and medium scale gravity waves. The ripples occurred ahead of the mesospheric front and their phase front were almost parallel to the phase of the mesospheric front and were almost perpendicular to the phase front of the gravity wave. Using wind measurements from a meteor radar located at São João do Cariri and simultaneous vertical temperature profiles from the TIMED/SABER satellite, on the night of the events and within the imager field of view, the atmospheric background environment in the mesosphere and lower thermosphere (MLT) was investigated in order to understand the instability process that caused the appearance of the ripples. Dynamic and convective instabilities have been pointed out as responsible for creation of ripples in the MLT. The observed ripples were advected by the neutral wind, they occurred into a region with negative lapse rate of the potential temperature and the Richardson number was negative as well. According to these characteristics, the ripple structures could be generated in the MLT region due to the predominance of convective instability.

    The environmental risk assessment of the veterinary pharmaceutical ivermectin is receiving significant attention. This paper assesses the capacity of the MS{center_dot}3 soil microcosm as a tool for targeting the environmental impact assessment of veterinary drugs, using ivermectin as model. Two screening MS{center_dot}3 were performed using different European soils; one with a soil collected in an agricultural station near to Madrid, Spain and a second with a soil collected in a farm area close to York, UK. Soils were fortified with ivermectin at the following ranges: 0.01-10 mg kg{sup -}1 and 0.1-100 mg kg{sup -}1 in the Madrid and York studies, respectively. The effects on earthworms, plants and soil microorganisms were assessed in the Madrid soil. Toxicity tests on aquatic organisms (algae, cladocerans and in vitro fish cell line RTLW1) were also conducted with the leachates. No effects were observed in earthworms and plants at any tested concentration; reduction in the respiration rate (< 5%) of soil microorganisms was detected. Earthworm/soil bioconcentration factors decreased with the increase in soil concentrations and were higher for the York soil. Effects on daphnids were observed in tested leachates; based on measured levels of ivermectin in the leachates an EC50 of about 0.5{mu}gL{sup -}1 can be estimated. Comparisons based on toxicity data and equilibrium partitioning confirmed that the main risk is expected to be related to the high sensitivity of cladocerans. The results confirm that MS{center_dot}3 systems are cost-effective tools for assessing the impact of veterinary pharmaceuticals when applied to agricultural land, as previously demonstrated for antimicrobials.

    Objective. Unusual manifestations are occasionally encountered in Langerhans cell histiocytosis and may be a source of confusion. The objective of this study was to determine the frequency of occurrence of the unusual manifestations in our case material. Design and patients. Thirty-four children, average age 4.4 years (range 3 months to 16 years) with 262 skeletal lesions of biopsy-proven Langerhans cell histiocytosis (LCH) were retrospectively reviewed to determine the frequency of occurrence of unusual manifestations defined either as an atypical location of a skeletal lesion or an atypical radiographic appearance of the lesion. Results. Twenty-four unusual lesions were found in this retrospective review. Among these were epiphyseal lesions, transphyseal lesions, extracranial `button` sequestra, posterior vertebral arch lesions, dural extension of vertebral lesions, and fluid-fluid levels. The finding of fluid-fluid levels has not previously been described in the radiologic literature. Involvement of unusual sites included clavicles and small bones of the hands and feet. Conclusions. Radiographic, computed tomographic, and magnetic resonance imaging of LCH yield a variety of unusual manifestations. Recognition of these varied appearances of LCH may prevent confusion of such appearances with other pathologic processes. When the unusual manifestation occurs as the initial finding of the disease, LCH should be included in the differential diagnosis. (orig.) With 7 figs., 10 refs.

    Enactment of scientific inquiry in classroom has attracted a great attention of science educators around the world. In this study, we examined two competent teachers' (one Grade 9 chemistry teacher and one Grade 4 science teacher) enactment of scientific inquiry in selected teaching units to reveal the characteristics of enacted inquiry at different grade levels by analyzing lesson sequence videos. The coding schemes for enacted inquiry consist of ontological properties and instructional practices. Pre-topic and post-topic teacher interviews and the two teachers' responses to a questionnaire were adopted to identify the factors influencing teacher's enactment. The results indicate that the two case teachers' enactment involved a range of inquiry activities. The enacted inquiry at fourth-grade level covered all the inquiry elements, tending to engage students in the whole procedure of inquiry. The ninth-grade chemistry class placed emphasis on the elements "making plans" to solve problems in authentic context. Important factors influencing the enactment include teacher's understanding about scientific inquiry, textbooks, assessment, students and resource. Implications for inquiry enactment and instruction improvement have been provided.

    Full Text Available Traditionally, Live High-Train High (LHTH interventions were adopted when athletes trained and lived at altitude to try maximising the benefits offered by hypoxic exposure and improving sea level performance. Nevertheless, scientific research has proposed that the possible benefits of hypoxia would be offset by the inability to maintain high training intensity at altitude. However, elite athletes have been rarely recruited as an experimental sample, and training intensity has almost never been monitored during altitude research. This case study is an attempt to provide a practical example of successful LHTH interventions in two Olympic gold medal athletes. Training diaries were collected and total training volumes, volumes at different intensities, and sea level performance recorded before, during and after a 3-week LHTH camp. Both athletes successfully completed the LHTH camp (2090 m maintaining similar absolute training intensity and training volume at high-intensity (> 91% of race pace compared to sea level. After the LHTH intervention both athletes obtained enhancements in performance and they won an Olympic gold medal. In our opinion, LHTH interventions can be used as a simple, yet effective, method to maintain absolute, and improve relative training intensity in elite endurance athletes.

    1 Hz GPS data recorded by the GNSS network of the Consejeria de Agricultura y Agua of the Murcia Region during the Mw 5.1 Lorca earthquake on May 11th 2011 is used as a test case. A Precise Point Positioning (PPP) approach is applied to analyse the earthquake-induced motion of the station LORC, located close to the epicenter. The results are validated using a conventional Double Differences (DD) processing. After applying sidereal and regional filters, the detected transient motion is about 20 millimeters in each component and clearly above noise level. The results from the two different processings are compared in view of the accuracy and applicability. The PPP approach described here can potentially be used for real-time analysis e.g. based on NTRIP streaming data. It may be used to set up an early warning system, as well as to gain real-time knowledge of ongoing earthquakes, extending the already-existing seismic information obtained from classical measurements.

    The asymptotic giant branch (AGB) stars X Her and TX Psc have been imaged at 70 and 160 microns with the PACS instrument onboard the Herschel satellite, as part of the large MESS (Mass loss of Evolved StarS) Guaranteed Time Key Program. The images reveal an axisymmetric extended structure with its axis oriented along the space motion of the stars. This extended structure is very likely to be shaped by the interaction of the wind ejected by the AGB star with the surrounding interstellar medium (ISM). As predicted by numerical simulations, the detailed structure of the wind-ISM interface depends upon the relative velocity between star+wind and the ISM, which is large for these two stars (108 and 55 km/s for X Her and TX Psc, respectively). In both cases, there is a compact blob upstream whose origin is not fully elucidated, but that could be the signature of some instability in the wind-ISM shock. Deconvolved images of X Her and TX Psc reveal several discrete structures along the outermost filaments, which coul...

    To introduce and emphasize the clinical and radiological findings of three talar body fatigue stress fractures in competitive athletes. Clinical and radiographic skeletal records of 24,562 athletes taken between 1962 and 2002 were retrospectively reviewed. Among these, 6851 files related to acute foot and ankle injuries or chronic post-traumatic sequelae were found. There were 925 (3.76%) stress fatigue fractures selected from the whole collection. Among these there were three cases (0.32%) of talar body stress fractures diagnosed in elite female gymnasts 15 - 17 years old. The negative first radiograph become positive 4-6 weeks later. Scintigraphy was positive at an early stage and consistent for the diagnosis. CT and MRI gave positive results 1-2 weeks after the beginning of symptoms which were always greatly diagnostic. The sports medicine literature lacks reports of talar body fatigue stress fractures. The poor initial sensitivity of radiography makes it problematic to establish an early diagnosis. A wise combination of scintigraphy, CT and MRI has therefore to be relied upon. Familiarity with this rare location for a stress fracture may prevent delayed diagnosis and long-lasting damage, both of which are important factors in competitive athletes. (orig.)

    The aim of this study was to qualitatively assess the disturbances of lived time in individuals with multiple drug dependencies. The research was conducted at Monar-Markot Center for Humanitarian Aid in Roznowice (Poland) in 2014 through direct, non-disguised observational study in a therapeutic community setting. Overall, 10 clients with multiple drug dependencies forming a newcomers group participated in. They previously abstained from usage for negligible periods of time. The measurements included participant observation of collective time regimes at the center; group discussions; written accounts by clients; Zimbardo Time Perspective Inventory; semi-structured interviews. It was found that the clients experienced difficulties in following a strict therapeutic temporal regime, and they also showed a concomitant need to accelerate time as it passed. They also suffered an unpleasant domination by traumatic past within lived time. Their time horizons appeared significantly shortened and their planning capacity impaired, while a distant (dissociated) future was fantasized about in a realistic manner. Altogether, their disturbances of lived time consisted of the propensity to overemphasize their past dimensions at the expense of their future, while a gap between a close and a distant future appeared.

    Orography is a well-known source of gravity and inertia-gravity waves in the atmosphere. Other sources, such as convection, are also known to be potentially important but the large amplitude of orographic waves over Scandinavia has generally precluded the possibility to study such other sources experimentally in this region. In order to better understand the origin of stratospheric gravity waves observed by the VHF radar ESRAD (Esrange MST radar) over Kiruna, in Arctic Sweden (67.88 N, 21.10 E), observations have been compared to simulations made using the Weather Research and Forecasting model (WRF) with and without the effects of orography and clouds. This case study concerns gravity waves observed from 00:00 UTC on 18 February to 12:00 UTC on 20 February 2007. We focus on the wave signatures in the static stability field and vertical wind deduced from the simulations and from the observations as these are the parameters which are provided by the observations with the best height coverage. As is common at this site, orographic gravity waves were produced over the Scandinavian mountains and observed by the radar. However, at the same time, southward propagation of fronts in the Barents Sea created short-period waves which propagated into the stratosphere and were transported, embedded in the cyclonic winds, over the radar site.

    The 13th Gravitational Wave Data Analysis Workshop took place in San Juan, Puerto Rico on the 19-22 January 2009. This annual event has become the established venue for presenting and discussing new results and techniques in this crucial subfield of gravitational wave astronomy. A major attraction of the event is that scientists working with all possible instruments gather to discuss their projects and report on the status of their observations. The Center for Gravitational Wave Astronomy at the University of Texas at Brownsville, USA (a National Aeronautics and Space Administration University Research Center and a National Science Foundation Center for Research Excellence in Science and Technology) jointly with the National Astronomy and Ionosphere Center (which operates the Arecibo Observatory) were the proud sponsors of the gathering this time. As in previous years, GWDAW13 was well attended by more than 100 participants from over 10 countries worldwide As this issue is going to press GEO, LIGO and VIRGO are undergoing new scientific runs of their instruments with the LIGO detectors holding the promise of increasing their operational sensitivity twofold as compared with the observations finished a couple of years ago. This new cycle of observations is a major milestone compared to the previous observations which have been accomplished. Gravitational waves have not been observed yet, but the instrumental sensitivity achieved has started producing relevant astrophysical results. In particular, very recently (Nature, 20 August 2009) a letter from the LIGO Scientific Collaboration http://www.ligo.org and the VIRGO Collaboration http://www.virgo.infn.it has set the most stringent limits yet on the amount of gravitational waves that could have come from the Big Bang in the gravitational wave frequency band where current gravitational wave detectors can observe. These results have put new constraints on the physical characteristics of the early universe. The proximity

    AIM: The aims of this study were to make an inventory of the disease in Ireland, to acquire better knowledge of the relationship between genetic makeup and phenotypic ocular presentation and, finally, through literature review and personal experience, to establish clear guidelines on best practice in the management of children with this rare condition both in terms of screening and follow-up. METHODS: All patients who attended the dermatology and genetic clinic in Our Lady\\'s Hospital for Sick Children, Crumlin, with incontinentia pigmenti (IP) were contacted and invited to attend the eye clinic for ocular assessment. Children who were already attending the ophthalmic services before commencement of the study had their charts reviewed for assessment. RESULTS: 11 of 19 patients agreed to attend the clinic for ocular assessment. Of these patients, nine had genetic testing. The mean age of the patients at the examination was 8 years (3 months to 29 years). In 10 patients, IP was the result of a spontaneous mutation, whereas the condition was inherited from an affected mother in one patient. Of the 11 patients with IP, 5 have visually significant ocular findings (47%). We describe the case history of four of these children briefly to outline the severity of this condition. CONCLUSION: Our patients had a significant percentage of ocular abnormalities (47%). We have outlined an examination schedule for patients with and without retinal pathology and recommend fluorescein angiography in patients with retinal pathology to fully determine the extent of ischaemia. Like other studies, early treatment with peripheral retinal photocoagulation to reduce the risk of retinal detachment is recommended in this study.

In our opinion, LHTH interventions can be used as a simple, yet effective, method to maintain absolute, and improve relative training intensity in elite endurance athletes. Key PointsElite endurance athletes, with extensive altitude training experience, can maintain similar absolute intensity during LHTH compared to sea level.LHTH may be considered as an effective method to increase relative training intensity while maintaining the same running/walking pace, with possible beneficial effects on sea level performance.Training intensity could be the key factor for successful high-level LHTH camp.

    Aerosol particles are regularly transported over long distances impacting air quality, health, weather and climate thousands of kilometers downwind of the source. During transport, particle properties are modified thereby changing the associated impact on the radiation budget. Although mineral dust is of key importance for the climate system many questions such as the change of the dust size distribution during long-range transport, the role of wet and dry removal mechanisms, and the complex interaction between mineral dust and clouds remain open. In June/July 2013, the Saharan Aerosol Long-range Transport and Aerosol-Cloud-Interaction Experiment (SALTRACE: http://www.pa.op.dlr.de/saltrace) was conducted to study the transport and transformation of Saharan mineral dust. Besides ground-based lidar and in-situ instruments deployed on Cape Verde, Barbados and Puerto Rico, the DLR research aircraft Falcon was equipped with an extended aerosol in-situ instrumentation, a nadir-looking 2-μm wind lidar and instruments for standard meteorological parameters. During SALTRACE, five large dust outbreaks were studied by ground-based, airborne and satellite measurements between Senegal, Cape Verde, the Caribbean, and Florida. Highlights included the Lagrangian sampling of a dust plume in the Cape Verde area on 17 June which was again measured with the same instrumentation on 21 and 22 June 2013 near Barbados. Between Cape Verde and Barbados, the aerosol optical thickness (500 nm) decreased from 0.54 to 0.26 and the stratification of the dust layers changed significantly from a rather homogenous structure near Africa to a 3-layer structure with embedded cumulus clouds in the Caribbean. In the upper part of the dust layers in the Caribbean, the aerosol properties were similar to the observations near Africa. In contrast, much more variability in the dust properties was observed between 0.7 and 2.5 km altitude probably due to interaction of the mineral dust with clouds. In our

    Three cases of Epstein-Barr virus (EBV)-negative post-transplant lymphoproliferative disease that occurred 6 to 8 years after renal transplantation are reported. The patients respectively had gastric mucosa-associated lymphoid tissue lymphoma, gastric diffuse large B-cell lymphoma, and atypical Burkitt lymphoma. Absence of EBV in the tissue samples was demonstrated by both in situ hybridization for EBV early RNA and polymerase chain reaction for EBV DNA. Patients were treated with reduction in immunosuppression and combined chemotherapy plus an anti-CD20 monoclonal antibody, rituximab. Despite the reduction in immunosuppression, patients had stable renal functions without loss of graft functions. The patient with atypical Burkitt lymphoma had an abnormal karyotype, did not respond to treatment completely, and died due to disease progression. The other patients are still alive and in remission 5 and 3 years after diagnosis, respectively. EBV-negative post-transplant lymphoproliferative diseases are usually late-onset and are reported to have poor prognosis. Thus, reduction in immunosuppression is usually not sufficient for treatment and more aggressive approaches like rituximab with combined chemotherapy are required.

  7. Invasive amebiasis and ameboma formation presenting as a rectal mass: An uncommon case of malignant masquerade at a western medical center

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    A 54-year-old man presented with rectal pain and bleeding secondary to ulcerated, necrotic rectal and cecal masses that resembled colorectal carcinoma upon colonoscopy. These masses were later determined to be benign amebomas caused by invasive Entamoeba histolytica, which regressed completely with medical therapy. In Western countries, the occurrence of invasive protozoan infection with formation of amebomas is very rare and can mistakenly masquerade as a neoplasm. Not surprisingly, there have been very few cases reported of this clinical entity within the United States. Moreover, we report a patient that had an extremely rare occurrence of two synchronous lesions, one involving the rectum and the other situated in the cecum. We review the current literature on the pathogenesis of invasive E. Histolytica infection and ameboma formation, as well as management of this rare disease entity at a western medical center.

    The setting for this case study is the Dolph Briscoe, Jr. Library, University of Texas Health Science Center at San Antonio, a health sciences campus with medical, dental, nursing, health professions, and graduate schools. During 2008-2009, major renovations to the library building were completed including office space for a faculty development department, multipurpose classrooms, a 24/7 study area, study rooms, library staff office space, and an information commons. The impetus for changes to the library building was the decreasing need to house collections in an increasingly electronic environment, the need for office space for other departments, and growth of the student body. About 40% of the library building was remodeled or repurposed, with a loss of approximately 25% of the library's original space. Campus administration proposed changes to the library building, and librarians worked with administration, architects, and construction managers to seek renovation solutions that meshed with the library's educational mission.

    Normal-pressure hydrocephalus is an almost curable disease, but the results of management are still not encouraging owing to the deceptive nature of the disease and its sensitivity to treatment. This has made the management of the disease controversial. The following self-documented report clarifies this. I have reported my experience in a scientific manner so that my colleagues can understand thoroughly certain facts related to intracranial hypertension. Achieving the optimal adjustment of the valve is a real challenge. I describe in detail the adjustment criteria I discovered. I believe that the use of biofeedback waves are almost the best way to make a proper adjustment of the valve, that is, if waves come from this machine and show increased tension of the facial muscles (high spiky waves) the valve adjustment has to be reduced without risking overdrainage. I have been observing my symptoms in some detail, which led me to a better understanding of the clinical pictures related to cerebrospinal fluid changes. I hope that uncovering my story can help with further research and improve management in this important and interesting field.

    Context. Measuring star formation at a local scale is important to constrain star formation laws. Yet, it is not clear whether and how the measure of star formation is affected by the spatial scale at which a galaxy is observed. Aims. We want to understand the impact of the resolution on the determination of the spatially resolved star formation rate (SFR) and other directly associated physical parameters such as the attenuation. Methods. We have carried out a multi-scale, pixel-by-pixel study of the nearby galaxy M33. Assembling FUV, Halpha, 8, 24, 70, and 100 micron maps, we have systematically compared the emission in individual bands with various SFR estimators from a resolution of 33 pc to 2084 pc. Results. We have found that there are strong, scale-dependent, discrepancies up to a factor 3 between monochromatic SFR estimators and Halpha+24 micron. The scaling factors between individual IR bands and the SFR show a strong dependence on the spatial scale and on the intensity of star formation. Finally, str...

    The purpose of this study was to describe how teamwork that effectively engaged patients and families, manifested itself in an acute rural care setting in order to inform the development of teamwork skills. One hundred and forty participants were included in the study representing providers, patients, family, hospital and clinical support personnel, education specialists and students. Using a modified grounded theory approach, and informed by activity theory, observational field notes and interview transcripts were analyzed. Through the analysis of 343 events of providers interacting with, or exchanging information about, patients, three patterns of teamwork emerged that facilitated patient-engaged care: uniprofessional, multiprofessional and interprofessional. The data indicated that providers navigated between these patterns, as well as others, throughout their workday. Providers should be skilled in applying the construct of situation awareness in order to adopt a pattern of teamwork that best facilitates patient-engaged care. Interventions that can enhance teamwork should focus on: valuing the perspectives of others; developing relational competence and resilience; employing reflective learning and shared decision-making skills; and incorporating principles of change theory for both individuals and systems.

    We have mapped the emission-line flux distributions and ratios as well as the gaseous kinematics of the inner 450 pc radius of the Seyfert 1 galaxy Mrk 766 using integral field near-IR J- and Kl-band spectra obtained with the Gemini nifs at a spatial resolution of 60 pc and velocity resolution of 40 km/s. Emission-line flux distributions in ionized and molecular gas extend up to ~ 300 pc from the nucleus. Coronal [S IX]{\\lambda}1.2523{\\mu}m line emission is resolved, being extended up to 150 pc from the nucleus. At the highest flux levels, the [Fe II]{\\lambda}1.257{\\mu}m line emission is most extended to the south-east, where a radio jet has been observed.The emission-line ratios [Fe II]{\\lambda}1.2570{\\mu}m/Pa{\\beta} and $H_2${\\lambda}2.1218{\\mu}m/Br{\\gamma} show a mixture of Starburst and Seyfert excitation; the Seyfert excitation dominates at the nucleus, to the north-west and in an arc-shaped region between 0.2" and 0.6" to the south-east at the location of the radio jet.

    We have mapped the gaseous kinematics and the emission-line flux distributions and ratios from the inner ~680pc radius of the Seyfert 1 galaxy Mrk79, using two-dimensional (2D) near-IR J- and Kl-band spectra obtained with the Gemini instrument NIFS at a spatial resolution of ~100pc and velocity resolution of ~40km/s. The molecular hydrogen flux distribution presents two spiral arms extending by ~700pc, one to the north and another to the south of the nucleus, with an excitation indicating heating by X-rays from the central source. The low velocity dispersion (sigma~50km/s) and rotation pattern supports a location of the H2 gas in the disk of the galaxy. Blueshifts observed along the spiral arm in the far side of the galaxy and redshifts in the spiral arm in the near side, suggest that the spiral arms are feeding channels of H2 to the inner 200pc. From channel maps along the H2 l2.1218um emission-line profile we estimate a mass inflow rate of ~4E-3 M_Sun/year, which is one order of magnitude smaller than the m...

    Objective:To identify the clinical manifestations of hump nosed viper envenomation and to recognize the available treatment methods to prevent complications.Methods: Descriptive observational study involving a series of1 543 patients admitted with hump nosed viper bite to 5 major hospitals in Sri Lanka was conducted. Data collection was done consecutively during February1990 and February2008. ExceptHypnale, identification of the biting snake was made by the corresponding author after visual examination of the dead or live snakes, which were brought to hospital.Results: Sixty seven(4.34%) patients developed systemic effects and two (0.1%) patients died due to effects of envenomation or complications of treatment. Systemic effects varied from coagulopathy, nephropathy to some neurological manifestations. Fifty nine (3.8%) patients had only coagulopathy and they received either, intravenous isotonic saline to ensure adequate urine out put i.e.0.5 mL/kg /hour or15 mL/kg of fresh frozen plasma(FFP). None of the patients that had coagulopathy developed renal failure. Contamination of the sample by mildly venomous species ofHypnale may have contributed to the low incidence of systemic complications.Conclusions: It is likely that early hydration with normal saline orFFP can prevent acute renal failure. FFP showed a tendency for early correction of coagulopathy. Role of FFP in hump nosed viper envenomation is worth studying in randomized double blind controlled clinical trials.

  20. Satellite observations of aerosol transport from East Asia to the Arctic: three case studies

    2010-11-01

    Full Text Available Vertical profiles of aerosols obtained with the CALIOP lidar onboard CALIPSO are used in conjunction with the GEOS-Chem chemical transport model and NOAA's HYSPLIT trajectory model to document three aerosol export events from East Asia to the Arctic that occurred in the year 2007. During each of these events CALIOP sampled the pollution plumes multiple times over periods of five to seven days. Meridional transport to the Arctic was rapid, taking 3–4 days and was accompanied by net diabatic heating of ~5 °C/day and precipitation in its ascending stage. Once in the Arctic transport was nearly isentropic with slow subsidence and radiative cooling at a rate of 1–1.5 °C/day. We find close agreement between modeled and observed plume in terms of length, altitude, thickness and, within the measurement uncertainties, extinction coefficient. In one event the satellite algorithm misclassifies the aerosol layer as ice clouds as a result of the relatively high depolarization ratio (0.06, likely caused by a somewhat high dust component in the aerosol mixture. The misclassification is more severe at daytime (67% of layers are misclassified than at nighttime (32%. The two most intense export events occurred in early spring within a three-week time span and are strongly related to a persisting blocking anticyclone that was located in the NW Pacific. Using 500 hPa geopotential height anomalies of these two events along with several others in 2007–2009 we develop a meteorological index that captures 40–60% of the variance of Asian transport events to the Arctic in winter and spring.

    Full Text Available istSOS (Istituto scienze della Terra Sensor Observation Service is an implementation of the Sensor Observation Service standard from Open Geospatial Consortium (OGC. The development of istSOS started in 2009 in order to provide a simple implementation of the Sensor Observation Service (SOS standard for the management, provision and integration of hydro-meteorological data collected in Canton Ticino (Southern Switzerland. istSOS is entirely written in Python and is based on reliable open source software like PostgreSQL/PostGIS and Apache/mod_wsgi. The authors during this presentation want to illustrate the latest software enhancements together with a real case in a production environment. Latest software enhancement includes the development of a RESTful service and of a Web-based graphical user interface that allows hydrologists a better interaction with measurements. This includes the ability of new services creation, addition of new sensors and relative metadata, visualization and manipulation of stored observations, registration of new measures and setting of system properties like observable properties and data quality codes. The study will show a real case application of the system for the provision of data to interregional partners and to a hydrological model for lake level forecasting and flooding hazard assessment. The hydrological model uses a combination of WPS (Web Processing Service and SOS for the generation of model input data. This system is linked with a dedicated geo-portal used by the civil protection for the management, alert and protection of population and assets of the Locarno area (Verbano Lake flooding. Practical considerations and technical issues will be presented and discussed.

    One-step apexification using mineral trioxide aggregate (MTA) has been reported as an alternative treatment modality with more benefits than the use of long-term calcium hydroxide for teeth with open apex. However, orthograde placement of MTA is a challenging procedure in terms of length control. This case series describes the sequence of events following apical extrusion of MTA into the periapical area during a one-step apexification procedure for maxillary central incisor with an infected immature apex. Detailed long-term observation revealed complete resolution of the periapical radiolucent lesion around the extruded MTA. These cases revealed that direct contact with MTA had no negative effects on healing of the periapical tissues. However, intentional MTA overfilling into the periapical lesion is not to be recommended.

    2013-01-01

    Objective Repetitive transcranial magnetic stimulation (rTMS) can enhance the excitement of the brain through adjusting the biological activities of the cerebral cortex and has wide biological effects, making it one basic mechanism of therapy for depression. In the treatment of unipolar depressive disorder, almost in every treatment method, hypomanic and manic shifts can be observed. There is still a lack of data regarding manic and hypomanic symptoms triggered by rTMS applications. Method We describe four cases with unipolar depression in which high-frequency rTMS over the left dorsolateral prefrontal cortex applied as an add-on antidepressive strategy may have induced a hypomanic episode. Results In these cases, 25 Hz rTMS combined with antidepressants may have contributed to the occurrence of hypomanic symptoms. Conclusion Using an intensive methodology of rTMS may induce hypomanic or manic symptoms. PMID:23618105

    Sensor inquirers cannot understand comprehensive or accurate observation capability information because current observation capability modeling does not consider the union of multiple sensors nor the effect of geospatial environmental features on the observation capability of sensors. These limitations result in a failure to discover credible sensors or plan for their collaboration for environmental monitoring. The Geospatial Environmental Observation Capability (GEOC) is proposed in this study and can be used as an information basis for the reliable discovery and collaborative planning of multiple environmental sensors. A field-based GEOC (GEOCF) information representation model is built. Quintuple GEOCF feature components and two GEOCF operations are formulated based on the geospatial field conceptual framework. The proposed GEOCF markup language is used to formalize the proposed GEOCF. A prototype system called GEOCapabilityManager is developed, and a case study is conducted for flood observation in the lower reaches of the Jinsha River Basin. The applicability of the GEOCF is verified through the reliable discovery of flood monitoring sensors and planning for the collaboration of these sensors. PMID:27999247

    Full Text Available Our retrospective study assessed the effects of treatment of early stage ONFH with extracorporeal shock wave therapy. 335 patients (528 hips were treated with shockwave therapy in our institution. Each patient underwent two sessions. The hips were divided into two groups according to whether the lateral pillar of the femoral head (LPFH was preserved: LPFH and non-LPFH groups. Patients were followed up at 3, 6, and 12 months after the treatment. Most of the patients (83.9% hips demonstrated pain reduction and improved mobility of the treated joint (visual analogue scale score, P=0.00006; Harris hip score, P=0.00091. During the follow-up period, 16 hips failed following femoral head collapse and required hip arthroplasty (2 hips in LPFH group and 14 hips in non-LPFH group. The lesion size decreased after ESWT. However, the differences were statistically not significant (LPFH group, P=0.091; non-LPFH group, P=0.087. A significant reduction in bone marrow edema was observed after treatment (LPFH group, P=0.007; non-LPFH group, P=0.016. High-energy extracorporeal shock wave therapy resulted in considerable improvement in early stage ONFH, which can effectively relieve pain and improve the function of the hip.

    Abell 2256 is one of the best known examples of a galaxy cluster hosting large-scale diffuse radio emission that is unrelated to individual galaxies. It contains both a giant radio halo and a relic, as well as a number of head-tail sources and smaller diffuse steep-spectrum radio sources. The origin of radio halos and relics is still being debated, but over the last years it has become clear that the presence of these radio sources is closely related to galaxy cluster merger events. Here we present the results from the first LOFAR Low band antenna (LBA) observations of Abell 2256 between 18 and 67 MHz. To our knowledge, the image presented in this paper at 63 MHz is the deepest ever obtained at frequencies below 100 MHz in general. Both the radio halo and the giant relic are detected in the image at 63 MHz, and the diffuse radio emission remains visible at frequencies as low as 20 MHz. The observations confirm the presence of a previously claimed ultra-steep spectrum source to the west of the cluster center w...

    Near-infrared (NIR) spectra that have an angular resolution of ~ 0.15 arcsec are used to examine the stellar content of the central regions of the nearby elliptical galaxy Maffei 1. The spectra were recorded at the Subaru Telescope, with wavefront distortions corrected by the RAVEN Multi-Object Adaptive Optics science demonstrator. The Ballick-Ramsey C_2 absorption bandhead near 1.76 microns is detected, and models in which 10 - 20% of the light near 1.8 microns originates from stars of spectral type C5 reproduce this feature. Archival NIR and mid-infrared images are also used to probe the structural and photometric properties of the galaxy. Comparisons with models suggest that an intermediate age population dominates the spectral energy distribution between 1 and 5 microns near the galaxy center. This is consistent not only with the presence of C stars, but also with the large HBeta index that has been measured previously for Maffei 1. The J-K color is more-or-less constant within 15 arcsec of the galaxy cen...

    Full Text Available The impacts of haze emphasized significance of hazards for human activities and importance of observations of aerosol vertical distribution. This study aimed to analyze the aerosol vertical distribution during a haze case at temporal and spatial aspects, using space-borne and ground-based Lidar observations over Jinhua Basin, Zhejiang province, as well as the Hybrid Single-Particle Lagrangian Integrated Trajectory (HSPLIT model and optical situ monitoring at Jinhua site. The results highlight three pollution peaks above the surface located in the upper and lower boundary layer in Jinhua Basin. The trajectory analysis shows the pollutants inside and outside the planetary boundary layer from different sources. Planetary boundary layer height (PBLH obtained from the space-borne Lidar observations was compared with that from ground-based Lidar observations. The absolute error between the two instruments is about 0.193 km. It is illustrated that the space-borne Lidar is an effective instrument for obtaining regional aerosol pollution in vertical section. Pollution transport near the ground is closely related with the terrain condition.

    Full Text Available Background: Breast cancer is now the most common cancer in many parts of India and the incidence varies from 12 to 31/100000, and is rising. Locally advanced breast cancer (LABC accounts for 30 - 35% of all cases of breast cancers in India. LABC continues to present a challenge and imposes a major health impact in our country. Materials and Methods: We carried out a analysis of our LABC patients who received neoadjuvant chemotherapy (NACT at our hospital over a 10-year period, from January 1995 to December 2004. We analyzed the response to NACT, disease-free survival (DFS, and overall survival (OS. Results: Patients with stages IIIA, IIIB, and IIIC were included. LABC comprised of 26.24% (609 patients of new patients. One hundred and twenty-eight (31.1% patients received NACT. Median age was 48 years and estrogen receptor was positive in 64%. Chemotherapy protocol was an FEC (5-Fluorouracil, Epirubicin, Cyclophosphamide regimen in the following doses: Cyclophosphamide 600 mg/m2, 5-FU 600 mg/m2, and Epirubicin 75 mg/m2 given every three weeks, six doses, followed by modified radical mastectomy (MRM and locoregional radiotherapy. The overall response rate (complete response (CR + partial response (PR was 84.4%, clinical CR (cCR was 13.3% and pathological CR (pCR was 7.8%. Median DFS and OS were 33 and 101 months, respectively. The disease-free survival (DFS and overall survival (OS at five years were 41 and 58%, respectively. Conclusions: This study analyzes the outcome in patients who received NACT, in the largest number of LABC patients from a single center in India, and our results are comparable to the results reported from other centers.

    The effectiveness of using an Ensemble Square Root Filter (EnSRF) to assimilate real Doppler radar observations on convective scale is investigated by applying the technique to a case of squall line on 12 July 2005 in midwest Shandong Province using the Weather Research and Forecasting (WRF) model. The experimental results show that: (1) The EnSRF system has the potential to initiate a squall line accurately by assimilation of real Doppler radar data. The convective-scale information has been added into the WRF model through radar data assimilation and thus the analyzed fields are improved noticeably. The model spin-up time has been shortened, and the precipitation forecast is improved accordingly. (2) Compared with the control run, the deterministic forecast initiated with the ensemble mean analysis of EnSRF produces more accurate prediction of microphysical fields. The predicted wind and thermal fields are reasonable and in accordance with the characteristics of convective storms. (3) The propagation direction of the squall line from the ensemble mean analysis is consistent with that of the observation, but the propagation speed is larger than the observed. The effective forecast period for this squall line is about 5-6 h, probably because of the nonlinear development of the convective storm.

    We present the results of observations of blazar PKS 1510-089 with the Herschel Space Observatory PACS and SPIRE instruments, together with multiwavelength data from Fermi/LAT, Swift, SMARTS and SMA. The source was found in a quiet state, and its far-infrared spectrum is consistent with a power-law with a spectral index of alpha ~ 0.7. Our Herschel observations were preceded by two 'orphan' gamma-ray flares. The near-infrared data reveal the high-energy cut-off in the main synchrotron component, which cannot be associated with the main gamma-ray component in a one-zone leptonic model. This is because in such a model the luminosity ratio of the External-Compton and synchrotron components is tightly related to the frequency ratio of these components, and in this particular case an unrealistically high energy density of the external radiation would be implied. Therefore, we consider a well-constrained two-zone blazar model to interpret the entire dataset. In this framework, the observed infrared emission is asso...

    We present the results of observations of blazar PKS 1510-089 with the Herschel Space Observatory PACS and SPIRE instruments, together with multiwavelength data from Fermi/LAT, Swift, SMARTS, and Submillimeter Array. The source was found in a quiet state, and its far-infrared spectrum is consistent with a power law with a spectral index of α ~= 0.7. Our Herschel observations were preceded by two "orphan" gamma-ray flares. The near-infrared data reveal the high-energy cutoff in the main synchrotron component, which cannot be associated with the main gamma-ray component in a one-zone leptonic model. This is because in such a model the luminosity ratio of the external-Compton (EC) and synchrotron components is tightly related to the frequency ratio of these components, and in this particular case an unrealistically high energy density of the external radiation would be implied. Therefore, we consider a well-constrained two-zone blazar model to interpret the entire data set. In this framework, the observed infrared emission is associated with the synchrotron component produced in the hot-dust region at the supra-parsec scale, while the gamma-ray emission is associated with the EC component produced in the broad-line region at the sub-parsec scale. In addition, the optical/UV emission is associated with the accretion disk thermal emission, with the accretion disk corona likely contributing to the X-ray emission.

    Many poisoned patients may only require a period of observation after their exposure. There are limited data describing the use of observation units for managing poisoned adult and pediatric patients. We performed a retrospective review of all patients reported to the ToxIC Case Registry between January 1, 2012 and December 31, 2013. Eligible patients included those who received a bedside consultation by a medical toxicologist and whose care was provided in an observation unit, or those who were admitted under the care of a medical toxicologist in an observation unit. A total of 15,562 poisonings were reported to the registry during the study period, of which 340 (2.2 %) involved patients who were cared for in an observation unit. Of these patients, 22.1 % were 18 years of age or younger, and the remaining 77.9 % were greater than 18 years of age. The most common reason for exposure was the intentional ingestion of a pharmaceutical agent in both adult (30.2 %) and pediatric patients (36.0 %). Alcohols (ethanol) (24.9 %), opioids (20.0 %), and sedative-hypnotics (17.7 %) were the most common agent classes involved in adult patient exposures. The most common agent classes involved in pediatric exposures were antidepressants (12.0 %), anticonvulsants (10.7 %), and envenomations (10.7 %). In adult patients, the most common signs and symptoms involved the nervous system (52.0 %), a toxidrome (17.0 %), or a major vital sign abnormality (14.7 %). In pediatric patients, the most common signs and symptoms involved the nervous system (53.3 %), a toxidrome (21.3 %), or a major vital sign abnormality (17.3 %). The results of this study demonstrate that a wide variety of poisoned patients have been cared for in an observation unit in consultation with a board-certified medical toxicologist. Patterns for the reasons for exposure, agents responsible for the exposure, and toxicological treatments will continue to evolve. Further study is needed to identify

    Very little is known about visual functional recovery following long-term naltrexone administration in opioid-dependent patients. In the present study, a portable event-related potential (ERP) working system was utilized to collect and record ERP in opioid-dependent patients and normal controls in visual half-field testing. In addition, the influence of long-term sustained naltrexone release on the visual nervous system was observed in opioid-dependent patients. Results revealed a significant main group effect in reaction time to visual signal stimulations. The reaction time of normal controls was shortest, but longest in opioid-dependent patients. The reaction time of long-term sustained naltrexone release group and compulsory detoxification group was similar to normal controls. A significant main group effect was also observed in P100 latency, and P100 latency in normal controls and the compulsory detoxification group was significantly decreased compared with the opioid-dependent patients. P100 amplitude at the Oz-electrode resulted in a significant main group effect. In particular, normal controls exhibited significant differences compared with long-term sustained release naltrexone and compulsory detoxification groups. These findings demonstrated that long-term sustained naltrexone release effectively ameliorated optic center function and improved visual sensitivity and reactions in opioid-dependent patients.

    A rare case of canine hepatozoonosis in a mongrel dog with para-clinico-pathological observations has been reported. The study included detailed haemato-biochemical changes at two stages, i.e. before treatment and after treatment with adopted therapy. Before therapy, blood picture revealed normocytic hypochromic anaemia and neutrophilic leucocytosis with variable counts of platelets. Thirty-seven percent of neutrophils were found infected with gametocytes of Hepatozoon canis. Following treatment, further decrease in haemoglobin value with a relative increase in lymphocyte count was seen. Biochemically, increase in alkaline phosphatase, blood urea nitrogen and creatinine levels along with hyperproteinemia was seen. The 14 days chemotherapy did not bring a respite for the dog and the level of parasitaemia was 33% after the treatment. The alkaline phosphatase and creatinine level further rose up following therapy with sulphadiazine and clindamycin. Continual study is required to explain the best possible therapeutic combination to deal H. canis.

    Non-thermal radiation has been predicted within bow shocks around runaway stars by recent theoretical works. We present X-ray observations towards the runaway stars $\\zeta$ Oph (Chandra and Suzaku) and BD+433654 (XMM-Newton) to search for the presence of non-thermal X-ray emission. We found no evidence of non-thermal emission spatially coincident with the bow shocks, nonetheless, diffuse emission is detected in the vicinity of $\\zeta$ Oph. After a careful analysis of its spectral characteristics we conclude that this emission has a thermal nature with a plasma temperature of $T \\approx 2 \\times10^{6}$ K. The cometary shape of this emission seems to be in line with recent predictions of radiation-hydrodynamic models of runaway stars. The case of BD+433654 is puzzling as non-thermal emission has been reported in a previous work for this source.

    Neurocognition and social cognition are the core deficits influencing social outcomes in patients with schizophrenia. These deficits are present in the prodromal phase, throughout the illness and in first-degree relatives. They are considered in the framework of neurodevelopmental or neurodegenerative models as well as candidates for endophenotypes of schizophrenia. Four clinical cases with patients reflecting different cognitive profiles were chosen to demonstrate heterogeneity of cognitive biases and their influence on social function in vivo. The patients had undergone a number of neurocognitive and social cognitive measures. Better functioning was observed in patients with less affected domains of emotional processing and theory of mind, while neurocognitive statuses were incongruent to levels of social functioning. Further investigation on large samples concerning capacity for empathy and its role in social functioning is needed.

    We have searched for 1980-1988 Solar Maximum Mission gamma-ray spectrometer data for transient emission on timescales from hours to approximately 12 days of broad gamma-ray lines at energies approximately 400 keV, which were reported by the High Energy Astronomy Observatory (HEAO) 1 and SIGMA experiments from two sources lying toward the Galactic center. The lines have been interpreted as the product of the annihilation of positrons in pair plasmas surrounding the black hole candidate 1E 1740.7-2942 and the X-ray binary 1H 1822-371. Our results from a combined exposure of approximately 1.5 x 10(exp 7)s provide no convincing evidence for transient emission of this line on any timescale between approximately 9 hr and approximately 1 yr. Our 3 sigma upper limits on the line flux during approximately 12 day intervals are characteristically 4.8 x 10(exp -3) photon/sq cm/s, while for approximately 1 day intervals our 3 sigma upper limits are characteristically 4.9 x 10(exp -3) photon/sq cm/s. These results imply a duty cycle of less than 1.3% for the transient line measured from 1H 1822-371 during a approximately 3 week interval in 1977 by HEAO 1, and a duty cycle of less than or = 0.8% for the transient line detected in 1990 and 1992 from 1E 1740.7-2942 on approximately 1 day timescales by SIGMA.

  7. Observer's observables. Residual diffeomorphisms

    2016-01-01

    We investigate the fate of diffeomorphisms when the radial gauge is imposed in canonical general relativity. As shown elsewhere, the radial gauge is closely related to the observer's observables. These observables are invariant under a large subgroup of diffeomorphisms which results in their usefulness for canonical general relativity. There are, however, some diffeomorphisms, called residual diffeomorphisms, which might be "observed" by the observer as they do not preserve her observables. The present paper is devoted to the analysis of these diffeomorphisms in the case of the spatial and spacetime radial gauges. Although the residual diffeomorphisms do not form a subgroup of all diffeomorphisms, we show that their induced action in the phase space does form a group. We find the generators of the induced transformations and compute the structure functions of the algebras they form. The obtained algebras are deformations of the algebra of the Euclidean group and the algebra of the Poincar\\'e group in the spat...

  8. The Role of Large-Coherent-Eddy Transport in the Atmospheric Surface Layer Based on CASES-99 Observations

    The analysis of momentum and heat fluxes from the Cooperative Atmosphere-Surface Exchange Study 1999 (CASES-99) field experiment is extended throughout the diurnal cycle following the investigation of nighttime turbulence by Sun et al. (J Atmos Sci 69:338-351, 2012). Based on the observations, limitations of Monin-Obukhov similarity theory (MOST) are examined in detail. The analysis suggests that strong turbulent mixing is dominated by relatively large coherent eddies that are not related to local vertical gradients as assumed in MOST. The HOckey-Stick Transition (HOST) hypothesis is developed to explain the generation of observed large coherent eddies over a finite depth and the contribution of these eddies to vertical variations of turbulence intensity and atmospheric stratification throughout the diurnal cycle. The HOST hypothesis emphasizes the connection between dominant turbulent eddies and turbulence generation scales, and the coupling between the turbulence kinetic energy and the turbulence potential energy within the turbulence generation layer in determining turbulence intensity. For turbulence generation directly influenced by the surface, the HOST hypothesis recognizes the role of the surface both in the vertical variation of momentum and heat fluxes and its boundary effect on the size of the dominant turbulence eddies.

    Full Text Available istSOS (Istituto scienze della Terra Sensor Observation Service is an implementation of the Sensor Observation Service (SOS standard from the Open Geospatial Consortium. The development of istSOS started in 2009 in order to provide a simple implementation of the SOS for the management, provision and integration of hydro-meteorological data collected in Canton Ticino (Southern Switzerland. istSOS is an Open Source, entirely written in Python and based on reliable software like PostgreSQL/PostGIS and Apache/mod_wsgi. This paper illustrates the latest software enhancements, including a RESTful Web service and a Web-based graphical user interface, which enable a better and simplified interaction with measurements and SOS service settings. The robustness of the implemented solution has been validated in a real-case application: the Verbano Lake Early Warning System. In this application, near real-time data have to be exchanged by inter-regional partners and used in a hydrological model for lake level forecasting and flooding hazard assessment. This system is linked with a dedicated geoportal used by the civil protection for the management, alert and protection of the population and the assets of the Locarno area. Practical considerations, technical issues and foreseen improvements are presented and discussed.

    2005-01-01

    Using XMM-Newton we have obtained the first X-ray observation covering a complete orbit of the longest period polar, V1309 Ori. The X-ray light curve is dominated by a short, bright phase interval with EPIC pn count rates reaching up to 15 cts/sec per 30 sec resolution bin. The bright phase emission is well described by a single blackbody component with kT_bb = (45 +- 3) eV. The absence of a bremsstrahlung component at photon energies above 1 keV yields a flux ratio F_bb/F_br > 6700. This represents the most extreme case of a soft X-ray excess yet observed in an AM Herculis star. The bright, soft X-ray emission is subdivided into a series of individual flare events supporting the hypothesis that the soft X-ray excess in V1309 is caused by accretion of dense blobs. In addition to the bright phase emission, a faint, hard X-ray component is visible throughout the binary orbit with an almost constant count rate of 0.01 cts/sec. Spectral modelling indicates that this emission originates from a complex multi-temper...

  11. From observation to understanding: Approach to analysis of wear mechanisms, Case of RCCAs and CRDM latch arms

    Component wear can affect the ability of a component to fulfill its required function. For a designer or user, it is reasonable to expect possible wear occurrence as soon as parts are in relative motion. It is less obvious to extend this possibility to motions with small or very small amplitudes and loads. However, it has to be admitted that such cases exist. It then becomes imperative to determine the wear mechanisms so that the lifetime of the components and the optimum date of their replacement can be predicted or the degradation can be remedied. For this purpose, standard and widely accepted practice is to carry out simulator tests. Through examples of wear from nuclear reactor components such as the RCCAs (Rod Cluster Control Assembly) and the CRDM (Control Rod Drive Mechanism) latch arms, an approach for understanding the wear mechanisms and controlling their effects can be undertaken. Cases of wear have been observed on real-life parts, but the first simulator tests have shown deviations from in-reactor behaviour. Comparative examination of the wear facies of actual parts which have operated in reactor or simulators, both control rods and CRDM latch arms, was the key starting point for a new analytical approach, incorporating the formulation of wear mechanism hypotheses which can account for the observed facies. Expert assessment thus highlighted the importance of the environment by revealing that the wear featured a large component linked to friction-assisted corrosion. By including this tribo-corrosion aspect, it became possible to reach understanding of the mechanisms and account for the wear observed in reactor and on simulators. Further well-controlled simulator tests then made it possible to verify the importance of the tribo-corrosion processes in a pressurized water medium. Analysis of the physical chemical behaviour of the original materials (austenitic stainless steel) also explains why these surface modifications limit or remedy wear

    Objective To research on the epidemiological characteristics of the prehospital cases in Zigong emergency rescue center. Methods We retrospectively analyzed the database of prehospital cases in Zigong emergency rescue center in 2009. And reviewed the prehospital disease spectrum, gender composition, age structure, the circadian and seasonal distribution, and the outcomes of these cases. Results A total of 4 588 prehospital victims in Zigong emergency rescue center were enrolled. In the study, six leading diseases were injury, poisoning and certain other consequences due to external causes (45. 6%), diseases of the circulatory system (15. 0%), diseases of the respiratory system (6. 3%), diseases of the nervous system (6. 0%), mental and behavioral disorders (5. 6%), and diseases of the digestive system (4. 9%). Male patients were more than female patients (P<0. 05). The proportion of the aged and the middle-aged was significantly larger than that of young population in the same districts (P<0. 05), and the occurrence of prehospital care usually peaked at 15:40 (F<0. 05). Prehospital care had a higher incidence in winter (P<0. 05), and the outcome of prehospital cases was mainly in hospital and in observation ward. The proportion of deaths was 3. 8%. Conclusion We can allocate emergency resources reasonably in prehospital care, and promote the ability of rescuing in order to meet people's medical demands on the basis of the epidemiological study in our city.%目的 研究自贡市急救中心院前急救流行病学特征.方法 回顾性分析2009年度自贡市急救中心出诊的院前急救数据,研究院前急救疾病谱及性别、年龄构成,并分析时刻及季节分布特点,描述院前急救转归.结果 2009年度自贡市急救中心院前急救共4 588例,排前6位疾病依次为损伤、中毒和外因的某些其他后果(45.6%),循环系统疾病(15.0%),呼吸系统疾病(6.3%),神经系统疾病(6.0%),精神和行为障碍(5.6

    We present results from eight months of Green Bank Telescope 8.7 GHz observations and nearly 18 months of Swift X-ray telescope observations of the radio magnetar SGR J1745–2900. We tracked the radio and X-ray flux density, polarization properties, profile evolution, rotation, and single-pulse behavior. We identified two main periods of activity. The first is characterized by approximately 5.5 months of relatively stable evolution in radio flux density, rotation, and profile shape, while in the second these properties varied substantially. Specifically, a third profile component emerged and the radio flux also became more variable. The single pulse properties also changed, most notably with a larger fraction of pulses with pulse widths ∼5–20 ms in the erratic state. Bright single pulses are well described by a log-normal energy distribution at low energies, but with an excess at high energies. The 2–10 keV flux decayed steadily since the initial X-ray outburst, while the radio flux remained stable to within ∼20% during the stable state. A joint pulsar timing analysis of the radio and X-ray data shows a level of timing noise unprecedented in a radio magnetar, though during the time covered by the radio data alone the timing noise was at a level similar to that observed in other radio magnetars. While SGR J1745–2900 is similar to other radio magnetars in many regards, it differs by having experienced a period of relative stability in the radio that now appears to have ended, while the X-ray properties evolved independently.

    Data Center facilities, prevalent in many industries and institutions are essential to California's economy. Energy intensive data centers are crucial to California's industries, and many other institutions (such as universities) in the state, and they play an important role in the constantly evolving communications industry. To better understand the impact of the energy requirements and energy efficiency improvement potential in these facilities, the California Energy Commission's PIER Industrial Program initiated this project with two primary focus areas: First, to characterize current data center electricity use; and secondly, to develop a research ''roadmap'' defining and prioritizing possible future public interest research and deployment efforts that would improve energy efficiency. Although there are many opinions concerning the energy intensity of data centers and the aggregate effect on California's electrical power systems, there is very little publicly available information. Through this project, actual energy consumption at its end use was measured in a number of data centers. This benchmark data was documented in case study reports, along with site-specific energy efficiency recommendations. Additionally, other data center energy benchmarks were obtained through synergistic projects, prior PG&E studies, and industry contacts. In total, energy benchmarks for sixteen data centers were obtained. For this project, a broad definition of ''data center'' was adopted which included internet hosting, corporate, institutional, governmental, educational and other miscellaneous data centers. Typically these facilities require specialized infrastructure to provide high quality power and cooling for IT equipment. All of these data center types were considered in the development of an estimate of the total power consumption in California. Finally, a research ''roadmap'' was developed

    We present survey data of six NH3 (J, K) = (1, 1), (2, 2), (3, 3), (4, 4), (5, 5), and (6, 6) lines, simultaneously observed with the Tsukuba 32 m telescope, in the main part of the central molecular zone of the Galaxy. The total number of on-source positions was 2655. The three lower transitions were detected with S/N > 3 at 2323 positions (93% of all the on-source positions). Among 2323, the S/N 's of (J, K) = (4, 4), (5, 5), and (6, 6) exceeded 3.0 at 1426(54%), 1150(43%), and 1359(51%) positions, respectively. Simultaneous observations of the lines enabled us to accurately derive intensity ratios with less systematic errors. Boltzmann plots indicate that there are two temperature components: cold (˜20 K) and warm (˜100 K). Typical intensity ratios of Tmb(2, 2)/Tmb(1, 1), Tmb(4, 4)/Tmb(2, 2), Tmb(5, 5)/Tmb(4, 4), and Tmb(6, 6)/Tmb(3, 3) were 0.71, 0.45, 0.65, and 0.17, respectively. These line ratios correspond to the diversity of the rotational temperature, which results from mixing of the two temperature components.

    1995-12-01

    During the 15 years that the U.S. Environmental Protection Agency (EPA) has supported university-based research centers, there have been many changes in mission, operating style, funding level, eligibility, and selection process. Even the definition of the term {open_quotes}research center{close_quotes} is open to debate. Shifting national priorities, political realities, and funding uncertainties have powered the evolution of research centers in EPA, although the agency`s basic philosophy on the purpose and value of this approach to research remains essentially unchanged. Today, EPA manages 28 centers, through the Office of Exploratory Research. These centers are administered under three distinct programs. Each program has its own mission and goals which guide the way individual centers are selected and operated. This paper will describe: (1) EPA`s philosophy of reserach centers, (2) the complicated history of EPA research centers, (3) coordination and interaction among EPA centers and others, (4) opportunities for collaboration, and (5) plans for the future.

    2012-02-01

    PURPOSE: To describe cases of postoperative endophthalmitis in the European Society of Cataract & Refractive Surgeons (ESCRS) study of the prophylaxis of endophthalmitis, compare characteristics of unproven cases and cases proven by culture or polymerase chain reaction, and compare the characteristics with those in other reported series. SETTING: Twenty-four ophthalmology units in Austria, Belgium, Germany, Italy, Poland, Portugal, Spain, Turkey, and the United Kingdom. METHODS: Univariable and multivariable logistic regression models were used to analyze data for statistical association of signs and symptoms in cases with proven or unproven endophthalmitis. Specific data describing characteristics of the cases were compared between the 2 types of cases. RESULTS: Data from 29 endophthalmitis cases were analyzed. Swollen lids and pain were statistically associated with proven cases of endophthalmitis on univariable regression analysis. Multivariable analysis indicated that swollen lids and an opaque vitreous were associated with proven cases. Five cases of endophthalmitis occurred in the cefuroxime-treated groups. No case of streptococcal infection occurred in the cefuroxime-treated groups. However, cases of infection due to streptococci showed striking differences in visual acuity and were associated with earlier onset. Characteristics in the 29 cases parallel results in previous studies, such as the Endophthalmitis Vitrectomy Study, although the addition of a control group in the ESCRS study elicited additional findings. CONCLUSION: Swollen lids, pain, and an opaque vitreous were statistically associated with proven endophthalmitis cases in the ESCRS study.

    The Polo-like kinase (Plk) family comprises four cell cycle serine/threonine kinases, Plk1-4. Among these, Plk1 has been most thoroughly characterized; it contains a conserved kinase domain and a C-terminal docking site for S/T-phosphorylated proteins (polo-box domain, PBD). Polo-like kinases are deregulated in oncogenesis and therefore constitute a therapeutic target for cancer. A high throughput screening campaign was carried out by the Pittsburgh Molecular Library Screening Center (PMLSC), using a fluorescence polarization assay with recombinant Plk1-PBD to monitor the inhibition of binding of an optimal phosphopeptide substrate motif with recombinant Plk1-PBD. Screening of 97,090 small molecule library samples provided by the NIH Small Molecule Repository distributed by DPI Galapagos led to 11 confirmed hits. The Pittsburgh MLSCN Chemistry Core selected one of the structurally most tractable hits, SID 861574, for chemical hit-to-probe development. A broad chemistry program was initiated that developed new strategies for 6-amino- and 6-hydroxy uracil synthesis as well as acylanilides, and generated a total of 70 analogs. Out of 46 analogues tested, none, nor the resynthesized hit, showed affinity to Plk1-PBD in the follow up assays. In contrast, re-assays of the original screening materials displayed activities similar to the original HTS assay. We ultimately concluded that an impurity in the commercial material led to the positive screening artifact. This case study highlights our development of a synthesis of 6-position functionalized uracil analogs, but also illustrates the importance of careful quality and compound stability monitoring of screening collections.

    Full Text Available Brittany H Eghaneyan,1 Katherine Sanchez,2 Diane B Mitschke2 1Department of Psychiatry, UT Southwestern Medical Center, Dallas, TX, USA; 2School of Social Work, The University of Texas at Arlington, Arlington, TX, USA Background: The collaborative care model is a systematic approach to the treatment of depression and anxiety in primary care settings that involves the integration of care managers and consultant psychiatrists, with primary care physician oversight, to more proactively manage mental disorders as chronic diseases, rather than treating acute symptoms. While collaborative care has been shown to be more effective than usual primary care in improving depression outcomes in a number of studies, less is known about the factors that support the translation of this evidence-based intervention to real-world program implementation. The purpose of this case study was to examine the implementation of a collaborative care model in a community based primary care clinic that primarily serves a low-income, uninsured Latino population, in order to better understand the interdisciplinary relationships and the specific elements that might facilitate broader implementation. Methods: An embedded single-case study design was chosen in order to thoroughly examine the components of one of several programs within a single organization. The main unit of analysis was semi-structured interviews that were conducted with seven clinical and administrative staff members. A grounded theory approach was used to analyze the interviews. Line-by-line initial coding resulted in over 150 initial codes, which were clustered together to rebuild the data into preliminary categories and then divided into four final categories, or main themes. Results: Four unique themes about how the implementation of a collaborative care model worked in this setting emerged from the interviews: organizational change, communication, processes and outcomes of the program, and barriers to

  6. Chronological observation in early radiation myelopathy of the cervical spinal cord; Gadolinium-enhanced MRI findings in two cases

    Energy Technology Data Exchange (ETDEWEB)

    Hirota, Saeko; Yoshida, Shoji; Soejima, Toshinori (Hyogo Medical Center for Adults, Akashi (Japan)) (and others)

    Gd-enhanced MR images of two patients with clinically and histopathologically diagnosed chronic progressive radiation myelitis (CPRM) were observed chronologically. One of them had had nasopharyngeal cancer and received radiotherapy at a dose of 100 Gy to the C1-2 level of the spinal cord. She developed CPRM 25 months after the termination of radiotherapy. The other had had malignant lymphoma originating from the tonsil and received chemoradiotherapy. The dose delivered to her cervical spinal cord was 40 Gy, and she developed CPRM 30 months later. Gd-enhanced MRI in the early phase revealed a small crescent-shaped nidus with or without a very small central nonenhanced area in both cases. Enhancement was not great. At that time, patients noticed only the inability to perceive pain and temperature or paresthesia in the opposite side. In a few months, MRI revealed a much more strongly enhanced and larger nidus with enlargement of a central nonenhanced area accompanied by long segmental cord enlargement. The patients' neurological symptoms had also progressed, with hemiparesis developing, for example. (author).

    1984-04-01

    Two cases of acinic cell carcinoma arising in the glossopalatine glands were examined with the electron microscope by means of conventional thin sectioning and freeze-fracturing. Light and electron microscopic observation revealed that the tumors consisted of three types of cells: serous-type, ductlike, and vacuolated cells. Serous-type cells had numerous secretory granules, some of which were discharged into the intercellular spaces. Ductlike cells were smaller, usually lacked secretory granules, and were similar to intercalated duct cells. Vacuolated cells had electron-opaque vacuoles in the cytoplasm. Our findings supported the hypothesis that acinic cell carcinoma may represent a neoplasm of multipotential duct cells which have differentiated mainly into granulated serous cells. Freeze-fracture images of this tumor revealed that tight junctions were composed of ten or more interlinked strands with elongation of basal frontier strands. These findings suggested that the junctional morphology of the tumor resembled that of developing salivary glands and was associated with the degree of cellular differentiation.

    @@Repeated respiratory tract infection is a frequently-occurring disease during childhood. At present, western medicine doctors generally adopt anti-infectives and immunomodulators to treat the disease, while traditional Chinese medicine doctors mainly administer decoction of Chinese herbs. The authors treated 46 cases of repeated respiratory tract infection from March 1990 to April 1996 by applying mild-moxibustion over points on the back with satisfactory therapeutic results. A report follows. Clinical Data All the 86 cases were outpatients in our hospital with duration of common cold for over 10 days and characterized by relapse of respiratory tract infection. There were over 7-time relapse of respiratory tract infection on each case within a year. Eighty-six cases were randomly divided into treatment group (46 cases) and control group (40 cases). Of the 46 cases in the treatment group, 22 were boys and 24 girls. 17 cases (36.9%) were 6 months to 4 years old, 18 (39.1%) 4 to 6 years, and 11 (23.9%) 6 to 12 years. Among the 40 cases in the control group, 19 cases were boys and 21 girls.

    We study the correlations between center vortices and Abelian monopoles for SU(3) gauge group. Combining fractional fluxes of monopoles, center vortex fluxes are constructed in the thick center vortex model. Calculating the potentials induced by fractional fluxes constructing the center vortex flux in a thick center vortex-like model and comparing with the potential induced by center vortices, we observe an attraction between fractional fluxes of monopoles constructing the center vortex flux. We conclude that the center vortex flux is stable, as expected. In addition, we show that adding a contribution of the monopole-antimonopole pairs in the potentials induced by center vortices ruins the Casimir scaling at intermediate regime.

    A preliminary study was conducted to explore techniques and to develop and calibrate methodologies that combine inferences from field and remote sensing data to quantify temporal and spatial variations in lake physical parameters, and to examine their effects on primary productivity, and carbon sequestration rates in artificial lakes. The Case II waters of Lake Nasser (6000 km2) in southern Egypt were used as a test site. The construction of the Aswan High Dam in the 1960's has had major impacts on the landscape in southern Egypt. It gave rise to Lake Nasser, an extensive (capacity: 1.6 x 1011 m3, length: 500 km, average width: 12 km, average depth 30m) reservoir in southern Egypt and northern Sudan. In this study, we analyzed temporal (1980-2004) satellite images acquired over Lake Nasser to investigate spatial and temporal variations in aquatic parameters (e.g., chlorophyll and suspended matter) across the lake, and to test the usefulness of a variety of sensors and algorithms typically used for studies of larger water systems for this specific site. The investigated datasets include Moderate Resolution Imaging Spectroradiometer (MODIS), Sea-viewing Wide Field-of-view Sensor (SeaWiFS), and Coastal Zone Color Scanner (CZCS). The following patterns were identified. First, we detected a general enrichment in chlorophyll and in suspended matter upstream compared to the downstream and in the tributaries (Khors) compared to the main channel. This observation is consistent with the reported variations in sediment thickness along the length of the Lake. Thick deposits of up to 25 m were reported at the 2nd Cataract some 350 km south of the Aswan High Dam compared to 1m thick deposits in the vicinity of the Dam. Second, we observed a general and progressive increase in suspended matter and chlorophyll content in the autumn consistent with patterns of annual flooding which carry excess silt, clay, and nutrients. Future work will focus on 1) characterizing trends in carbon

    Grassland ecosystem is critical for survival of herbivores and plays an important role in conservation and management of wildlife. These habitats are widely studied for various issues, including biodiversity, biomass assessment, carrying capacity, etc. Woody species ingression in grasslands is one such important aspect that needs critical attention in protected area as this leads to shrinking of grasslands habitat. This study presents a case of Ronda grassland in Kanha National Park - a well-known protected area in India, known for its herbivore diversity and hard-ground Barasingha (Rucervus duvaceli branderi), in particular. Long-term satellite observation for five decades was carried out to understand spatio-temporal changes. Declassified Corona satellite data, aerial photographs along with satellite datasets in the subsequent period were utilised for this study. The study revealed that 88 ha (16% of Ronda and surrounding) have been ingressed during 1962-2011, in and around Ronda grassland of Kanha National Park. Rates of ingression on linear transects were found to be 60-120 m per decade. Field studies and NDVI analysis along the edge of grassland pixels as well as inside region using 1972 as baseline data, indicated woody vegetation replacing area of grassland. It was noted that Butea monosperma is invading more than other species in Ronda grassland, particularly along the stream where moisture availability is higher. Grassland habitats in Kanha are thus shrinking and thus leading to reduction in the area available for herbivore population which has increased in recent years. This can lead to severe impact on carrying capacity of these grasslands.

Clinical research has shown that the capsule has a good curative effect on chronic gastritis related to pyrolic Helicobacterium. Among the 53 cases in the treatment group, clinical observation showed cure in 6 cases, obvious effect in 18 cases, effect in 24 cases, no effect on 5 cases, with a total effective rate of 90.5%. Of the 50 cases in the control group, cure was found in 5 cases, obvious effect in 13 cases, effect in 20 cases, no effect in 12 cases, the total effective rate being 76%. The total effective rate in the treatment group was higher than that in the control group. The rate of eliminating pyrolic Helicobacterium in the treatment group was 66.04%, similar to that in the control group. In a follow-up visit 6 months later, the recurrence rate in the treatment group was 13.33%, obviously lower than that of 41.66% in the control group.
