Montazeri, Ali; Torkan, Behnaz; Omidvari, Sepideh

2007-04-04

The Edinburgh Postnatal Depression Scale (EPDS) is a widely used instrument to measure postnatal depression. This study aimed to translate and to test the reliability and validity of the EPDS in Iran. The English language version of the EPDS was translated into Persian (Iranian language) and was used in this study. The questionnaire was administered to a consecutive sample of 100 women with normal (n = 50) and caesarean section (n = 50) deliveries at two points in time: 6 to 8 weeks and 12 to 14 weeks after delivery. Statistical analysis was performed to test the reliability and validity of the EPDS. Overall 22% of women at time 1 and 18% at time 2 reported experiencing postpartum depression. In general, the Iranian version of the EPDS was found to be acceptable to almost all women. Cronbach's alpha coefficient (to test reliability) was found to be 0.77 at time 1 and 0.86 at time 2. In addition, test-rest reliability was performed and the intraclass correlation coefficient was found to be 0.80. Validity as performed using known groups comparison showed satisfactory results. The questionnaire discriminated well between sub-groups of women differing in mode of delivery in the expected direction. The factor analysis indicated a three-factor structure that jointly accounted for 58% of the variance. This preliminary validation study of the Iranian version of the EPDS proved that it is an acceptable, reliable and valid measure of postnatal depression. It seems that the EPDS not only measures postpartum depression but also may be measuring something more.

The U.S. Department of Energy originally created the National Analytical Management Program (NAMP) to help coordinate its analytical capabilities and to address national needs in technology and resources. In support of this mission, the NAMP established a subcommittee to promote training and education in radiochemistry to avert the predicted loss in expertise. In cooperation with the U.S. Environmental Protection Agency and university partners, the NAMP developed a series of two-hour webinar presentations by experts on different topics relevant to radiochemistry. These webinars are intended to be of interest to those already in the workforce who may need a refresher course or a better understanding of specific radiochemistry topics. The live webinars include slides presentation, and engage the attendees by giving them the opportunity to ask questions during the live event through the web-cast interface. Certificates may be given for attendance during the live webinar. The success of these webinars relies not only on the presenters who are internationally recognized experts but also on how we promote them: we advertised them through a dedicated web site, social networks or flyers. Another important point is that they are free are accessible online in 2 formats: audio-video recording and pdf files. Recorded and archived versions comprise a library vital to future generations of radio-chemists and scientists interested in radiochemistry. The first webinar, An Overview of Actinide Chemistry, was presented on April 20, 2012. The overwhelmingly positive feedback from participants clearly demonstrates that the NAMP webinars are making a difference by providing unique educational opportunities in radiochemistry.

Calibration and performance testing of electronic personal dosimeters (EPD)

International Nuclear Information System (INIS)

Banaga, H.A.

2008-04-01

In modern radiation protection practices, active personal dosimeters are becoming absolutely necessary operational tools for satisfying the ALARA principle. The aim of this work was to carry out calibration and performance testing of ten electronic personal dosimeters (EPD) used for the individual monitoring. The EPDs were calibrated in terms of operation radiation protection quantity, personal dose equivalent, Hp (10). Calibrations were carried out at three of x-ray beam qualities described in ISO 4037 namely 60, 100 and 150 kV in addition to Cs-137 gamma ray quality. The calibrations were performed using polymethylmethacrylate (PMMA) phantom with dimensions 20*20*15 cm 3 . Conversion coefficient Hp (10)/K air for the phantom was also calculated. The response and linearity of the dosimeter at the specified energies were also tested. The EPDs tested showed that the calibration coefficient ranged from 0.60 to 1.31 and an equivalent response for the specified energies that ranged from 0.76 to 1.67. The study demonstrated the possibility of using non standard phantom for calibrating dosimeters used for individual monitoring. The dosimeters under study showed a good response in all energies except the response in quality 100 kV. The linearity of the dosimeters was within ±15%, with the exception of the quality 100 kV where this limit was exceeded.(Author)

A proposal for rational thorium utilization: thorims-nes

International Nuclear Information System (INIS)

Kurukawa, K.; Erbay, L. B.

1997-01-01

In this study, a globally applicable system depending on a new philosophy has been introduced for solving the problems connected with nuclear safety, ratio-waste, anti-nuclear proliferation and terrorism and public/institutional acceptance and economy. This rational thorium breeding fuel-cycle system named as THORIMS-NES (Thorium Molten- Salt Nuclear Energy Synergetics ) appears to be particularly promising and can be the way of nuclear power development. THORIMS-NES depends on three principles: I. Thorium utilization, II. Application of molten-fluoride fuel technology and III. Separation of fissile producing breeders and power producing reactors. Thorium fuel cycle has benefit on the reduction of trans-U elements and for recycling fuels produced by all kinds of military, research and industrial reactors. A system for the realization of THORIMS-NES has been introduced by the explanation of connections/relations between facilities. In this study, the status of countries/groups working on Th and Th fuel cycle has been summarized. Additionally, the resultant announcement of the International Conference on Thorium Molten Salt Reactor Development (8-11 April, 1997, Santa Monica) has been mentioned to present the cooperation of scientists and engineers for the realization of THORIMS-NES

Underlying persistent psychological difficulties have been found to moderate potential adverse effects of maternal postpartum depression (PPD) on parenting and infant development. The authors examined whether mothers presenting postpartum depressive symptoms showed higher levels of personality pathology and more insecure state of mind regarding attachment compared to nondepressed mothers. Participants (N = 85) were assessed with the Edinburgh Postnatal Depression Scale (EPDS), the Present State Examination, the Adult Attachment Interview, and the Structured Clinical Interview for DSM-IV Axis II. Mothers with high EPDS scores were more likely to have a preoccupied insecure state of mind and to have personality disorder compared with mothers scoring below clinical cutoff. Furthermore, multiple regression analysis showed that personality disorder and AAI classification were independently related to EPDS score, and that these two factors together accounted for 48% of the variance in EPDS score. Findings are discussed in terms of heterogeneity in PPD populations and underline the importance of examining potential coexisting psychological difficulties when studying PPD.

Recubrimientos sol-gel obtenidos por deposición electroforética (EPD sobre metales

Castro, Y.

2000-12-01

Full Text Available Sol-gel process is a suitable method for the production of glass-like coatings onto metals, acting as barrier against oxidation and providing an increased resistance to corrosion. Hybrid and inorganic coatings of different compositions have been used for coating several metals by using techniques like dipping, spin-coating and spraying. Although these methods lead to good properties the final coatings are restricted by the thin thickness (up to 2 μm, thus limiting the application range. Electrophoretic deposition (EPD is considered a highly versatile technique for producing homogeneous thicker coatings. The aim of this work deals with the preparation of coatings onto metals by EPD from hybrid silica sols (TEOS, MTES and from colloidal silica suspensions where the hybrid sols constitute the suspending medium. Both the solutions and the suspensions have been studied in terms of viscosity, density and conductivity. Furthermore, the physical parameters associated to EPD, such as deposition time and current density, have been also studied, taking into account the additional contribution to the layer formed by EPD occurring by dipping during withdrawal. The coatings obtained by dipping and by EPD have been characterised by perfilometry and optical microscopy.

El proceso sol-gel es un método de gran interés para la producción de películas vítreas sobre metales, que actúan como barrera protectora frente a la oxidación y aumentan su resistencia a la corrosión. Se han obtenido recubrimientos inorgánicos e híbridos de distintas composiciones sobre distintos metales usando técnicas como inmersión, centrifugado y pulverización. Aunque estos métodos proporcionan recubrimientos con buenas propiedades los espesores obtenidos son bajos (inferiores a 2 mm, lo que limita sus posibilidades de aplicación. La deposición electroforética (EPD se perfila como una técnica de gran versatilidad para la obtención de recubrimientos homogéneos de

Electrochemical behaviour of silica basic hybrid coatings deposited on stainless steel by dipping and EPD

International Nuclear Information System (INIS)

Castro, Y.; Duran, A.; Damborenea, J.J.; Conde, A.

2008-01-01

The aim of this work is the characterisation of the corrosion behaviour of stainless steel (AISI 304) substrates coated by dipping and electrophoretic deposition (EPD) from a sol-gel basic sol. Particulate silica sols (labelled NaSi) were prepared by basic catalysis from ethyltriethoxysilane (TEOS), methyltriethoxysilane (MTES) and sodium hydroxide. Coatings between 2 and 10 μm were prepared by using concentrated and diluted sols by dipping and EPD process and the corrosion behaviour of the coated substrates were studied through potentiodynamic and impedance spectroscopy measurements (EIS). Potentiodynamic studies of coatings produced by dipping reveal a strong dependence of the protective properties with the concentration of the sol. This behaviour was confirmed by EIS showing that only the coatings obtained from concentrated sol present enough protective properties. On the contrary, EPD coatings prepared from diluted NaSi sol showed an excellent corrosion resistance, maintaining a pure capacitive behaviour for long periods of immersion. EPD deposition is thus proposed as a good alternative method for obtaining thicker and denser coatings with good protective properties from dilute and stable sols

Highlights: • A bio-ceramic n-MAO/EPD coating was prepared by combined MAO and EPD technique. • The precipitates of Ca/P compound are formed on the surface samples during immersion. • The n-MAO/EPD coating with HA dense structure has a favorable anti-corrosion effect. • Two degradation mechanism models for the n-MAO and n-MAO/EPD coating were proposed. - Abstract: The bio-ceramic composite coatings have been fabricated on ZK60 magnesium (Mg) alloy to improve its bio-corrosion resistance in a simulated body fluid (SBF). Firstly, micro-arc oxidation coatings (n-MAO coating) with the addition of zirconium oxide (ZrO{sub 2}) and cerium oxide (CeO{sub 2}) nano-particles were prepared by MAO technique on ZK60Mg alloy in alkaline electrolyte. Secondly, nano-hydroxyapatite (HA) was deposited on the surface of n-MAO coatings by using electrophoretic deposition (EPD) technique. The degradation behavior of the coated samples was investigated by means of immersion tests and electrochemical impedance spectroscopy (EIS) in the SBF at 36.5 ± 0.5 °C. The variation of phase composition, surface and cross-section morphology of coatings at different immersion stages were analyzed by X-ray diffraction (XRD) and scanning electron microscopy (SEM), respectively. The results showed that the precipitation layer with biological activity formed on the surface of coated samples during the SBF immersion, which can inhibit Mg alloys from degrading effectively. The n-MAO/EPD composite coating with HA dense structure has a favorable anti-corrosion effect compared to the n-MAO coating. Degradation mechanism model of the corrosion process at different corrosion stages for two kinds of coatings were proposed. The long-term corrosion protection of the n-MAO/EPD composite coating was governed significantly by the synergistic effect of phase composition stability and micro structural integrity.

Surface free energy of TiC layers deposited by electrophoretic deposition (EPD)

Gorji, Mohammad Reza; Sanjabi, Sohrab

2018-01-01

In this study porous structure coatings of bare TiC (i.e. 20 nm, 0.7 µm and 5/45 µm) and core-shell structures of TiC/NiP synthesized through electroless plating were deposited by EPD. Room temperature surface free energy (i.e. γs) of TiC and TiC/NiP coatings were determined via measuring contact angles of distilled water and diiodemethane liquids. The effect of Ni-P shell on spreading behavior of pure copper on porous EPD structures was also investigated by high temperature wetting experiments. According to the results existence of a Ni-P layer around the TiC particles has led to roughness (i.e. at least 0.1 µm), and porosity mean length (i.e. at least 1 µm) increase. This might be related to various sizes of TiC agglomerates formed during electroless plating. It has been observed that room temperature γs changed from 44.49 to 54.12 mJ.m-2 as a consequence of particle size enlargement for TiC. The highest and lowest (67.25 and 44.49 mJ.m-2) γs were measured for TiC nanoparticles which showed 1.5 times increase in surface free energy after being plated with Ni-P. It was also observed that plating Ni-P altered non-spreading (θs > 100 o) behavior of TiC to full-spreading ((θs 0o)) which can be useful for preparation of hard coatings by infiltration sintering phenomenon. Zeta potential of EPD suspensions, morphology, phase structure and topography of as-EPD layers were investigated through Zetasizer, field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD) and atomic force microscopy (AFM) instruments respectively.

Highlights: • Adding CeO{sub 2}/ZrO{sub 2} nano-particles to modify the properties of n-MAO coating. • A bio-ceramic n-MAO/EPD composite coating was prepared by two-step methods. • The n-MAO/EPD composite coating with HA has a favorable anti-corrosion effect. - Abstract: A bio-ceramic composite coating was fabricated on ZK60 magnesium (Mg) alloy using combined micro-arc oxidation (MAO) with electrophoretic deposition (EPD) technique. The MAO coating as the basal layer was produced in alkaline electrolyte with (n-MAO coating) and without (MAO coating) the addition of CeO{sub 2} and ZrO{sub 2} nano-particles, respectively. A hydroxyapatite (HA) coating as the covering layer was deposited on the n-MAO coating to improve the biological properties of the coating (n-MAO/EPD composite coating). The morphology and phase composition of three treated coatings were investigated by scanning electron microscope (SEM) and X-ray diffraction (XRD). The corrosion resistance of these coatings was evaluated with potentiodynamic polarization tests and immersion tests in simulated body fluid (SBF) at 36.5 ± 0.5 °C. The XRD spectra showed that the CeO{sub 2} and ZrO{sub 2} peaks can be collected in the n-MAO coating, and HA particles exists in the n-MAO/EPD composite coating. The results of corrosion tests indicated that the n-MAO/EPD composite coating owned increased bioactivity and long-term protective ability compared with the MAO coating and the n-MAO coating. Thus Mg alloy coated with the n-MAO/EPD composite coating should be more suited as biodegradable bone implants.

Sánchez Prieto, Sebastián; Da Silva, Antonio; Rodriguez Polo, Oscar; Parra Espada, Pablo; Gutierrez Molina, Oscar; Fernandez Salgado, Javier

Solar Orbiter is the next heliospheric mission sponsored by ESA. The launch is planned for 2017 and it will be as close as 0.28 AU from the Sun. One of the instruments for Solar Orbiter is the Energetic Particle Detector (EPD) responsible for measuring energies from 2 keV to 200 MeV/n. EPD consists of four detectors, Electron Proton Telescope (EPT), High Energy Telescope (HET), SupraThermal Electrons, Ions, & Neutrals (STEIN), and Suprathermal Ion Spectrograph (SIS), plus the Instrument Control Unit called ICU. The Space Research Group of the University of Alcalá in Spain is the responsible for developing the ICU. In this work we present the development status of the ICU after the Critical Design Review. We also address the planned activities for the next year including the development of the Engineering and Qualification Model (EQM) and Flight Model (PM). Special focus is paid to the software and verification & validation activities.

Splicing Factor Prp8 Interacts With NES(AR) and Regulates Androgen Receptor in Prostate Cancer Cells.

Wang, Dan; Nguyen, Minh M; Masoodi, Khalid Z; Singh, Prabhpreet; Jing, Yifeng; O'Malley, Katherine; Dar, Javid A; Dhir, Rajiv; Wang, Zhou

2015-12-01

Androgen receptor (AR) plays a pivotal role in the development of primary as well as advanced castration-resistant prostate cancer. Previous work in our lab identified a novel nuclear export signal (NES) (NES(AR)) in AR ligand-binding domain essential for AR nucleocytoplasmic trafficking. By characterizing the localization of green fluorescence protein (GFP)-tagged NES(AR), we designed and executed a yeast mutagenesis screen and isolated 7 yeast mutants that failed to display the NES(AR) export function. One of those mutants was identified as the splicing factor pre-mRNA processing factor 8 (Prp8). We further showed that Prp8 could regulate NES(AR) function using short hairpin RNA knockdown of Prp8 coupled with a rapamycin export assay in mammalian cells and knockdown of Prp8 could induce nuclear accumulation of GFP-tagged AR in PC3 cells. Prp8 expression was decreased in castration-resistant LuCaP35 xenograft tumors as compared with androgen-sensitive xenografts. Laser capture microdissection and quantitative PCR showed Prp8 mRNA levels were decreased in human prostate cancer specimens with high Gleason scores. In prostate cancer cells, coimmunoprecipitation and deletion mutagenesis revealed a physical interaction between Prp8 and AR mainly mediated by NES(AR). Luciferase assay with prostate specific antigen promoter-driven reporter demonstrated that Prp8 regulated AR transcription activity in prostate cancer cells. Interestingly, Prp8 knockdown also increased polyubiquitination of endogenous AR. This may be 1 possible mechanism by which it modulates AR activity. These results show that Prp8 is a novel AR cofactor that interacts with NES(AR) and regulates AR function in prostate cancer cells.

The results of the Independent Orbiter Assessment (IOA) of the Failure Modes and Effects Analysis (FMEA) and Critical Items List (CIL) are presented. The IOA effort first completed an analysis of the Electrical Power Distribution and Control (EPD and C)/Remote Manipulator System (RMS) hardware, generating draft failure modes and potential critical items. To preserve independence, this analysis was accomplished without reliance upon the results contained within the NASA FMEA/CIL documentation. The IOA analysis of the EPD and C/RMS hardware initially generated 345 failure mode worksheets and identified 117 Potential Critical Items (PCIs) before starting the assessment process. These analysis results were compared to the proposed NASA Post 51-L baseline of 132 FMEAs and 66 CIL items.

Full Text Available The article performs a Critical Study of the Discourse of a fragment of the video “Narconovelas- Movimiento ciudadano #noen3caines” (Garcia & Cartagena, 2013 which gives an account of the citizens’ initiative Noen3caínes. In this initiative citizens question the media, and what it constitutes as a social response. The general objective is to interpret the social response called Noen3Caínes, from the meanings that are proposed in the video analysis. Noen3Caínes had concrete effects on the advertisement of the TV series of RCN in Colombia “Tres Caínes”. At least 13 brands withdrew their advertising thanks to public pressure from the Internet because they considered that his image was not akin to that proposal on television, a matter which has no precedent in the history of the media in Colombia.

Full Text Available Abstract Background Abstractor training is a key element in creating valid and reliable data collection procedures. The choice between in-person vs. remote or simultaneous vs. sequential abstractor training has considerable consequences for time and resource utilization. We conducted a web-based (webinar abstractor training session to standardize training across six individual Cancer Research Network (CRN sites for a study of breast cancer treatment effects in older women (BOWII. The goals of this manuscript are to describe the training session, its participants and participants' evaluation of webinar technology for abstraction training. Findings A webinar was held for all six sites with the primary purpose of simultaneously training staff and ensuring consistent abstraction across sites. The training session involved sequential review of over 600 data elements outlined in the coding manual in conjunction with the display of data entry fields in the study's electronic data collection system. Post-training evaluation was conducted via Survey Monkey©. Inter-rater reliability measures for abstractors within each site were conducted three months after the commencement of data collection. Ten of the 16 people who participated in the training completed the online survey. Almost all (90% of the 10 trainees had previous medical record abstraction experience and nearly two-thirds reported over 10 years of experience. Half of the respondents had previously participated in a webinar, among which three had participated in a webinar for training purposes. All rated the knowledge and information delivered through the webinar as useful and reported it adequately prepared them for data collection. Moreover, all participants would recommend this platform for multi-site abstraction training. Consistent with participant-reported training effectiveness, results of data collection inter-rater agreement within sites ranged from 89 to 98%, with a weighted average of

1988-01-01

The results of the Independent Orbiter Assessment (IOA) of the Failure Modes and Effects Analysis (FMEA) and Critical Items List (CIL) are presented. The IOA effort first completed an analysis of the Electrical Power Distribution and Control/Electrical Power Generation (EPD and C/EPG) hardware, generating draft failure modes and potential critical items. To preserve independence, this analysis was accomplished without reliance upon the results contained within the NASA FMEA/CIL documentation. The IOA results were then compared to the NASA FMEA/CIL baseline with proposed Post 51-L updates included. A resolution of each discrepancy from the comparison was provided through additional analysis as required. The results of that comparison is documented for the Orbiter EPD and C/EPG hardware. The IOA product for the EPD and C/EPG analysis consisted of 263 failure mode worksheets that resulted in 42 potential critical items being identified. Comparison was made to the NASA baseline which consisted of 211 FMEA and 47 CIL items.

Bringing a Global Issue Closer to Home: The OSU Climate Change Webinar Series

Science.gov (United States)

Jentes Banicki, J.; Dierkes, C.

2012-12-01

When people think about the effects of climate change, many will still picture that iconic lone polar bear clinging to a shrinking iceberg in Antarctica. But many don't realize that the impacts that we will face here at home could also be severe, directly affecting the food we eat, the health we have, and the natural environments we appreciate. To help better explain and ultimately localize those impacts for Great Lakes residents, 10 departments within Ohio State University partnered in 2009 to create the Global Change, Local Impact webinar series. The monthly series brings in experts from around the Great Lakes region to discuss issues and impacts we will encounter regionally as our climate changes. Originally designed as a small series for Ohioans, the series has broadened to focus on Great Lakes-related issues, with more than 4,500 attendees representing 500 organizations in governmental agencies, academia, non-profit groups, private industry, and the legislature from around the country. Over the past two years, the OSU Climate Team expanded its educational reach by partnering with external groups like the Centers for Disease Control and Prevention, Great Lakes Regional Water Program, National Oceanic and Atmospheric Administration, and the Great Lakes Sea Grant Network to help deliver the most knowledgeable experts and resources for each Great Lake-focused climate topic and archive those resources on its www.changingclimate.osu.edu web site. As a result of these collaborative efforts, participants say the webinars are one of their primary resources for climate-related research information in the region, with 80-90% polled saying they use this information as an unbiased resource to help not only understand how climate change could affect local concerns like public health, agriculture, and infrastructure, but what they in their vocations and daily lives can do to prepare for it. For scientists and practitioners, this series serves as the perfect low carbon venue

1996-11-01

A double blind study was made on a group of 35 children, 8 of whom were allergic to Grass and 27 allergic to Pteronyssinus and Farinae Dermatophagoides. We verified the efficacy and tolerability of a new immunotherapy called E.P.D. (Enzyme Potentiated Desensitization). This particular immunotherapy consists in an intradermal injection of a mix made up of an allergic solution at extremely low doses and an enzyme, beta-glucuronidase. The vaccine is administered once a year, two weeks before pollen peaks for children with seasonal allergies and two times a year, in February and November, for children with non-seasonal allergies (Dermatophagoides). The results, statistically analyzed on the basis of a symptoms score, showed good clinical efficacy in patients affected by both seasonal and non-seasonal allergies. Due to the clinical effectiveness, easy administration and excellent tolerability of the immunotherapy, E.P.D. is particularly suited for treating or reducing allergic symptoms in allergic children.

Comparative analysis of seven viral nuclear export signals (NESs reveals the crucial role of nuclear export mediated by the third NES consensus sequence of nucleoprotein (NP in influenza A virus replication.

Directory of Open Access Journals (Sweden)

Nopporn Chutiwitoonchai

Full Text Available The assembly of influenza virus progeny virions requires machinery that exports viral genomic ribonucleoproteins from the cell nucleus. Currently, seven nuclear export signal (NES consensus sequences have been identified in different viral proteins, including NS1, NS2, M1, and NP. The present study examined the roles of viral NES consensus sequences and their significance in terms of viral replication and nuclear export. Mutation of the NP-NES3 consensus sequence resulted in a failure to rescue viruses using a reverse genetics approach, whereas mutation of the NS2-NES1 and NS2-NES2 sequences led to a strong reduction in viral replication kinetics compared with the wild-type sequence. While the viral replication kinetics for other NES mutant viruses were also lower than those of the wild-type, the difference was not so marked. Immunofluorescence analysis after transient expression of NP-NES3, NS2-NES1, or NS2-NES2 proteins in host cells showed that they accumulated in the cell nucleus. These results suggest that the NP-NES3 consensus sequence is mostly required for viral replication. Therefore, each of the hydrophobic (Φ residues within this NES consensus sequence (Φ1, Φ2, Φ3, or Φ4 was mutated, and its viral replication and nuclear export function were analyzed. No viruses harboring NP-NES3 Φ2 or Φ3 mutants could be rescued. Consistent with this, the NP-NES3 Φ2 and Φ3 mutants showed reduced binding affinity with CRM1 in a pull-down assay, and both accumulated in the cell nucleus. Indeed, a nuclear export assay revealed that these mutant proteins showed lower nuclear export activity than the wild-type protein. Moreover, the Φ2 and Φ3 residues (along with other Φ residues within the NP-NES3 consensus were highly conserved among different influenza A viruses, including human, avian, and swine. Taken together, these results suggest that the Φ2 and Φ3 residues within the NP-NES3 protein are important for its nuclear export function

NES consensus redefined by structures of PKI-type and Rev-type nuclear export signals bound to CRM1.

Güttler, Thomas; Madl, Tobias; Neumann, Piotr; Deichsel, Danilo; Corsini, Lorenzo; Monecke, Thomas; Ficner, Ralf; Sattler, Michael; Görlich, Dirk

2010-11-01

Classic nuclear export signals (NESs) confer CRM1-dependent nuclear export. Here we present crystal structures of the RanGTP-CRM1 complex alone and bound to the prototypic PKI or HIV-1 Rev NESs. These NESs differ markedly in the spacing of their key hydrophobic (Φ) residues, yet CRM1 recognizes them with the same rigid set of five Φ pockets. The different Φ spacings are compensated for by different conformations of the bound NESs: in the case of PKI, an α-helical conformation, and in the case of Rev, an extended conformation with a critical proline docking into a Φ pocket. NMR analyses of CRM1-bound and CRM1-free PKI NES suggest that CRM1 selects NES conformers that pre-exist in solution. Our data lead to a new structure-based NES consensus, and explain why NESs differ in their affinities for CRM1 and why supraphysiological NESs bind the exportin so tightly.

Social participation in young people with nonepileptic seizures (NES): A qualitative study of managing legitimacy in everyday life.

Science.gov (United States)

Karterud, Hilde Nordahl; Haavet, Ole Rikard; Risør, Mette Bech

2016-04-01

This qualitative study explored social participation in young people with nonepileptic seizures (NES), particularly how legitimacy of illness is managed in everyday life. Young people with NES, all female and aged between 14 and 24 years (N=11), were interviewed and followed up over a 14-month period. The transcripts were analyzed using thematic analysis. Four main themes were elaborated: 1) Delegitimizing experiences from families, schoolteachers, colleagues, and employers were part of everyday life. 2) Fear of being exposed to delegitimizing events resulted in the young people trying to conceal the diagnosis; for some, this resulted in isolation from all social arenas, apart from their closest relationships. 3) Support from close relationships was protective against delegitimization and contributed towards greater social participation. 4) Perceiving NES as a legitimate disorder contributed to increased social participation. We found a relationship between legitimacy of illness experienced by the participants and the extent to which they either participated or retreated socially. Those who had an illness perception that was personally meaningful experienced their condition as being more legitimate and participated more socially. Copyright © 2016 Elsevier Inc.

Géochimie des résines et asphaltènes Geochernistry of Resins and Asphaltenes

2006-11-01

Full Text Available Les produits lourds des huiles brutes (résines et asphaltènes jouent un rôle important dans la genèse et l'accumulation du pétrole, ainsi que dans la mise en production par des méthodes conventionnelles ou par récupération assistée. Les asphaltènes et résines sont considérés ici comme des fragments de kérogène, avec une structure d'ensemble comparable : ils peuvent constituer des intermédiaires dans la genèse de l'huile brute par dégradation thermique du kérogène. De plus, la pyrolyse des asphaltènes séparés à partir d'un pétrole biodégradé peut produire de nouveaux hydrocarbures saturés qui reproduisent la fraction saturée primitive, détruite par la dégradation ; on peut ainsi disposer d'un nouvel outil pour corréler ce type d'huiles brutes. Les produits lourds semblent défavorisés par rapport aux hydrocarbures, dans la migration de la roche-mère vers le réservoir, où les résines et asphaltènes sont proportionnellement moins abondants. La structure physique des asphaltènes et résines dans les pétroles, et en particulier l'existence d'une macrostructure du type micelles ou agrégats, est probablement responsable de la viscosité élevée des huiles lourdes. Une meilleure connaissance de cette macrostructure pourrait suggérer de nouvelles méthodes pour diminuer la viscosité et améliorer la récupération des huiles lourdes. The heavy constituents of crude oil (resins and asphaltenes play an important role in generation and accumulation of petroleum, and also in production by conventional and enhanced oil recovery processes. Asphaltenes and resins are considered here as small fragments of kerogen, with a comparable overall structure: they may act as intermediate compounds in oil generation by thermal breakdown of kerogen. Furthermore, pyrolysis of asphaltenes separated from a degraded crude oil is able to generate a new saturated hydrocarbon fraction which duplicates the original one, now degraded

We sought to examine the concordance of two suicidal ideation items from the Patient Health Questionnaire-9 (PHQ-9) and the Edinburgh Postnatal Depression Scale (EPDS), to evaluate the prevalence of suicidal ideation among pregnant women, and to assess the co-occurrence of suicidal ideation with antepartum depressive symptoms. A cross-sectional study was conducted among 1,517 pregnant women attending prenatal care clinics in Lima, Peru. Item 9 of the PHQ-9 assesses suicidal ideation over the last 14 days while item 10 of the EPDS assesses suicidal ideation in the past 7 days. The two suicidal ideation items have a high concordance rate (84.2 %) but a moderate agreement (the Cohen's kappa = 0.42). Based on the PHQ-9 and the EPDS, 15.8 and 8.8 % of participants screened positive for suicidal ideation, respectively. Assessed by the PHQ-9, 51 % of participants with suicidal ideation had probable depression. In prenatal care clinics, screening for suicidal ideation is needed for women with and without depressive symptoms. Future studies are needed to identify additional predictors of antepartum suicidality, determine the appropriate duration of reporting period for suicidal ideation screening, and assess the percentage of individuals with positive responses to the two suicidal ideation items at high risk of planning and attempting suicide.

Les scènes hivernales dans la peinture du Siècle d'or hollandais

Directory of Open Access Journals (Sweden)

Martine Tabeaud

2010-10-01

Full Text Available Les scènes d'hiver connaissent leur apogée au Siècle d'or hollandais. En se focalisant sur les représentations de la neige et du froid, il est possible de voir s'il existe un lien entre ces tableaux et le climat de l'époque, voire une concomitance entre les types d'hiver réels et peints. Le succès de ces scènes d'hiver aidant, il apparaît que nombre de peintres ont fait fi du climat de l'époque et ont réalisé des scènes de genre hivernales, au point de créer une véritable imagerie. C'est ainsi que la rudesse des hivers de la période froide du Petit Âge Glaciaire a globalement disparu dans les représentations au profit d'hivers festifs.The winter scenesare at their optimum during the Dutch Golden Age. When one focuses on the winter and coldness representations, one might wonder if the paintings and the real weather are correlated. If they are, do the paintings genuinely show how the weather was when they were painted? As the winter scenes became appreciated, the painters started to paint without taking into account the real weather. Eventually they painted genre scenes of the winter time and almost developed a series of winter scenes' image. Therefore the unusual rough coldness of the Little Ice Age winters has generally disappeared of the paintings, joyful winter scenes being preferred.

Full Text Available Dans cet article nous proposons des modèles de structures chimiques de kérogènes et d'asphaltènes de roche. Nous avons choisi de représenter les kérogènes appartenant aux trois types classiques de matières organiques aux stades d'évolution suivants : - début de la diagenèse sensu-stricto; - début de la catagenèse (formation de l'huile; - fin de la catagenèse (formation du gaz. Les asphaltènes représentés correspondent à la phase de formation de l'huile. Nous avons tenu compte des données d'analyse obtenues sur des échantillons naturels : analyse élémentaire, microscopie électronique, RMN 13C, thermogravimétrie, analyse fonctionnelle, dégradation par pyrolyse. Afin d'obtenir une représentation chimique ayant une valeur statistique suffisante, nous avons choisi une masse moléculaire de 25 000 environ, identique pour les trois kérogènes au début de la diagenèse, et une masse de 8000 environ pour les asphaltènes associés. Nous avons ensuite dessiné à l'échelle moléculaire les structures correspondantes. This paper proposes models for the chemical structures of kerogens and asphaltenes from rocks. The kerogens belonging to the three conventional types of organic matter are represented in the following stages of evolution: (1 beginning of diagenesis sensu stricto,(2 beginning of catagenesis (formation of oil, and (3 end of catagenesis (formation of gas. The asphaltenes represented here correspond to the phase of oil formation. Models are based on analytical data obtained on natural samples, i. e. elemental analysis, electron microscopy, 13C NMR, thermogravimetry, functional analysis and pyrolysis. To get enough statistical value for the chemical modelling, a same molecular mass of about 25 000 was chosen for the three kerogens at the beginning of diagenesis. A molecular mass of about 8000 was chosen for the related asphaltenes. The chemical structures were then constructed at the molecular scale.

Full text: Multi-Walled Carbon Nano tubes (MWCNT) were deposited onto Indium-Tin-Oxide (ITO)-coated glass substrates by introducing the use of Electrophoretic Deposition (EPD) as the method. The Multi-Walled Carbon Nano tubes (MWCNT) were dispersed ultrasonically in ethanol and sodium hydroxide (NaOH) to form stable suspension. The addition of Sodium Hydroxide in ethanol can stabilize the suspension, which was very important step before the deposition take place. Two substrates of Indium-Tin-Oxide(ITO)-coated glass placed in parallel facing each other (conductive side) into the suspension. The deposition occurs at room temperature, which the distance fixed at 1 cm between both electrodes and the voltage level applied was fixed at 400 V, respectively. The deposition time also was fixed at 30 minutes. The deposited ITO-Glass with Multi-Walled Carbon Nano tubes (MWCNT) will be characterized using Scanning Electron Microscope (SEM), Atomic Force Microscope (AFM), and Raman Microscope. The images of SEM shows that the Multi -Walled Carbon Nano tubes (MWCNT) were distributed uniformly onto the surface of ITO-Glass. The deposited ITO-Glass with Multi-Walled Carbon Nano tubes (MWCNT) could be the potential material in various practical applications such as field emission devices, fuel cells, and super capacitors. Electrophoretic deposition (EPD) technique was found to be an efficient technique in forming well distribution of Multi-Walled Carbon Nano tubes (MWCNT) onto ITO-Glass substrates, as proved in characterization methods, in which the optimum conditions will play the major role.

Full Text Available La multiplicité des introductions ou translocations de poissons, mollusques ou crustacés s'est largement amplifiée dans les dernières décennies et s'est accompagnée de multiples introductions d'agents pathogènes dans les hydrosystèmes naturels. L'analyse de la diversité des sources de ces agents pathogènes montre que certaines voies sont encore largement sous-évaluées aujourd'hui. L'amélioration apportée aux méthodologies et aux techniques d'identification a récemment permis un progrès spectaculaire dans la traçabilité des agents pathogènes et dans l'analyse de leurs introductions. Elle apporte, en partie, les clarifications nécessaires pour tenter de faire le bilan des introductions mais pose nettement le problème du seuil de perception de l'intrus. Une revue de la littérature a permis de recenser environ une centaine d'introductions relativement récentes d'agents pathogènes dans les hydrosystèmes naturels européens. Les caractères biologiques lato sensu favorables à la naturalisation des agents pathogènes introduits sont présentés. La diversité et la non-prédictibilité des impacts consécutifs à ces introductions sont ensuite détaillées à la lumière des études de terrain et de l'écologie théorique de la relation hôte-pathogène. Un cadre conceptuel d'analyse de risque est succinctement délimité pour évaluer ces introductions et des recommandations sont proposées.

Size and molecular weight determination of polysaccharides by means of nano electrospray gas-phase electrophoretic mobility molecular analysis (nES GEMMA).

Size, size distribution and molecular weight (MW) determination of nanoparticles and that are for example large polymers, are of great interest and pose an analytical challenge. In this context, nano electrospray gas-phase electrophoretic mobility molecular analysis (nES GEMMA) is a valuable tool with growing impact. Separation of single-charged analytes according to their electrophoretic mobility diameter (EMD) starting from single-digit EMDs up to several hundred nm diameters is possible. In case of spherical analytes, the EMD corresponds to the dry nanoparticle size. Additionally, the instrument is capable of number-based, single-particle detection following the recommendation of the European Commission for nanoparticle characterization (2011/696/EU). In case an EMD/MW correlation for a particular compound class (based on availability of well-defined standards) exists, a nanoparticle's MW can be determined from its EMD. In the present study, we focused on nES GEMMA of linear and branched, water-soluble polysaccharides forming nanoparticles and were able to obtain spectra for both analyte classes regarding single-charged species. Based on EMDs for corresponding analytes, an excellent EMD/MW correlation could be obtained in case of the branched natural polymer (dextran). This enables the determination of dextran MWs from nES GEMMA spectra despite high analyte polydispersity and in a size/MW range, where classical mass spectrometry is limited. EMD/MW correlations based on linear (pullulans, oat-ß-glucans) polymers were significantly different, possibly indicating challenges in the exact MW determination of these compounds by, for example, chromatographic and light scattering means. Despite these observations, nES GEMMA of linear, monosaccharide-based polymers enabled the determination of size and size-distribution of such dry bionanoparticles. © 2018 The Authors.

2006-11-01

Full Text Available The adsorption isotherms for phenol and 4-chlorophenol from water onto asphaltenes flocculated in bulk and asphaltenes deposited on silica were established by frontal analysis chromatography at 293, 298, 303, and 308 K. The adsorption was more important with asphaltenes flocculated in bulk and corresponded to a Freundlich isotherm mechanism. The high adsorbed amount of phenols suggests possible migration of phenols through the loose asphaltene structure. Isotherms observed with the silica coated by asphaltenes showed that adsorption occurs in two stages corresponding probably to two different organizations of solute molecules at the surface. Les isothermes d'adsorption du phénol et du 4-chlorophénol en solution dans l'eau sur des asphaltènes floculés en masse et sur des asphaltènes déposés sur de la silice ont été déterminés par analyse chromatographique frontale à 293, 298, 303 et 308 K. L'adsorption sur des asphaltènes floculés en masse était la plus importante avec des isothermes correspondant à un mécanisme de Freundlich. La quantité élevée de phénols adsorbés suggère une migration possible des molécules du phénol à travers la structure peu compacte des asphaltènes. Les isothermes observés dans le cas de silice tapissée d'asphaltènes ont montré que l'adsorption se produit en deux étapes correspondant probablement à deux organisations différentes des molécules de soluté à la surface.

[CHU Habib-Bourguiba, Service de radiotherapie oncologique, Sfax (Tunisia)

2010-01-15

Purpose: The objective of this work was the study of in vivo dosimetry performed in a series of 54 patients receiving total body irradiation (T.B.I.) at the Salah-Azaiz Institute of Tunis since 2004. In vivo dosimetry measurements were compared to analytically calculated doses from monitor units delivered. Patients and method: The irradiation was conducted by a linear accelerator (Clinac 1800, Varian, Palo Alto, USA) using nominal X-rays energies of 6 MV and 18 MV, depending on the thickness of the patient at the abdomen. The dose was measured by semi-conductors p-type E.P.D.-20. These diodes were calibrated in advance with an ionization chamber 'P.T.W. Farmer' type of 0.6 cm{sup 3} and were placed on the surface of plexiglas phantom in the same T.B.I. conditions. A study of dosimetric characteristics of semi-conductors E.P.D.-20 was carried out as a function of beam direction and temperature. Afterwards, we conducted a comparative analysis of doses measured using these detectors during irradiation to those calculated retrospectively from monitor units delivered to each patient conditioned by T.B.I.. Results: Experience showed that semi-conductors are sensitive to the angle of beam radiation (0-90 degrees) and the temperature (22-40 Celsius degrees). The maximum variation is respectively 5 and 7%, but in our irradiation conditions these correction factors are less than 1%. The analysis of the results of the in vivo dosimetry had shown that the ratio of the average measured doses and analytically calculated doses at the abdomen, mediastinum, right lung and head are 1.005, 1.007, 1.0135 and 1.008 with a standard deviation 'type A' respectively of 3.04, 2.37, 7.09 et 4.15%. Conclusion: In vivo dosimetry by semi-conductors is in perfect agreement with dosimetry by calculation. However, in vivo dosimetry using semiconductors is the only technique that can reflect the dose actually received instantly by the patient during T.B.I. given the many factors

Full Text Available The asphaltene interactions in model solutions were studied using a technique based on the electrical conductivity measurement. Interactions with n-heptane, resins, surfactants, water, phenol and NaCI were investigated. The conclusions drawn from this study confirmed previous opinions on aggregation mechanism of asphaltenes in solutions. They confirmed also the interpretation of asphaltene behaviour in terms of colloidal solution theories. Les interactions des asphaltènes avec leur environnement moléculaire dans des solutions modèles ont été étudiées par la mesure de la conductivité électrique de ces solutions. Les interactions avec le n-heptane, des résines, des tensioactifs, l'eau, le phénol et le chlorure de sodium ont été explorées. Les conclusions tirées de cette étude ont confirmé certaines hypothèses faites sur les mécanismes d'agrégation des asphaltènes en solution, en particulier dans le cadre de la théorie des solutions colloïdales.

Aim: To reevaluate the psychometric characteristics of the Malay version of the Edinburgh Postnatal Depression Scale among a sample of postpartum Malay women attending the Bakar Bata Health Center in Alor Setar, Kedah, North West of Peninsular Malaysia. Materials and methods: 64 women between 4 to 12 weeks postpartum were recruited for there validation study. They were given questionnaires on socio-demography, the 21-item Malay version of the Beck Depression Inventory II (BDI-II) and the 10-item Malay version of the Edinburgh Postnatal Depression Scale (EPDS). All the participants were later interviewed using the Hamilton Depression Rating Scale (HDRS-17) and the Composite International Diagnostic Interview (CIDI). All diagnoses were made based on the Tenth Edition of the International Classification of Diseases (ICD-10) Results: 9 women (14.1%) were diagnosed to have significant depression (7 mild depressive episodes and 2 moderate depressive episodes according to ICD-10). EPDS was found to have good internal consistency (Cronbach alpha =0.86) and split half reliability (Spearman split half coefficient = 0.83). The instrument also showed satisfactory discriminant and concurrent validity as evidenced by the statistically significant difference in EPDS scores between the depressed group and their non-depressed counterparts (Mann Whitney U test: 2 tailed p value Depression Scale in identifying postpartum depression among recently delivered Malay women attending the Bata Bata Health Center in Alor Setar, Kedah, North West of Peninsular Malaysia.

The effect of PTFE addition was investigated for the electrophoretic deposition (EPD) of hydrous ruthenium oxide electrodes. Mechanical stability of electrode layers, together with deposition yield, was enhanced by using hydrous ruthenium oxide/PTFE dispersions. High supercapacitor performance was obtained for the electrodes prepared with 2% PTFE and 10% water. When PTFE content was higher, the rate capability became poor with low electronic conductivity; higher water content than 10% resulted in non-uniform depositions with poor cycleability and power capability. When electrodes were heat treated at 200 deg. C for 10 h, the specific energy was as high as 17.6 Wh/kg based on single electrode (at 200 W/kg); while utilizable energy was lower with heat treatment time of 1 and 50 h, due to the high resistance and gradual crystallization, respectively. With PTFE addition and heat treatment at 200 deg. C for 10 h, the specific capacitance was increased by 31% (460 → 599 F/g at ca. 0.6 mg/cm 2 ) at 10 mV/s, and the deposition weight was increased up to 1.7 mg/cm 2 with initial capacitance of 350 F/g

Cryo-scanning electron microscopy has confirmed the system inhomogeneity. A two phase system was clearly highlighted. The flocculation process was followed during n-heptane addition by scattering measurements and microscopy observations. Small angle X-ray scattering (SAXS appears as a powerful tool for non-fractionated systems, as crude oil or other heavy derivatives. Density fluctuations were observed for a vacuum residue. L'industrie pétrolière est souvent confrontée a des problèmes industriels importants liés, entre autre, à la présence d'une forte concentration d'asphaltènes dans les fluides traités. Une meilleure connaissance de la composition de ces molécules et de l'évolution de leur structure colloïdale en solution ou dans leur milieu naturel est d'une grande importance pour mieux comprendre les mécanismes mis en jeu, et ainsi, pouvoir agir et limiter les problèmes rencontrés. Les asphaltènes correspondent à la fraction insoluble dans le n-heptane. Les molécules solubilisées dans l'alcane sont appelées maltènes et peuvent à leur tour être fractionnées par chromatographie en phase liquide; on obtient alors trois nouvelles fractions appelées résines, aromatiques et saturées. La plupart des travaux de recherche réalisés sur ces molécules complexes concernent la détermination de la composition chimique obtenue à l'aide de diverses techniques d'analyse telles la spectroscopie infrarouge et la résonance magnétique nucléaire. En revanche, peu d'informations sur la macrostructure colloïdale des asphaltènes sont disponibles dans la littérature. La détermination de la masse moléculaire a été le premier objectif : plusieurs méthodes, comme l'osmométrie à tension de vapeur, ont été appliquées. La conclusion principale de ces déterminations est la grande

Full Text Available Lorsque les larves de Monogènes (oncomiracidiums établissent leur premier contact avec l'hôte, cela correspond à un changement fondamental dans leur mode de vie. La disparition de quelques structures sensorielles et l'acquisition de nouvelles en témoignent ; mais il existe certainement d'autres types de changements encore inconnus au niveau du système nerveux. Le développement larvaire lui-même, à ce moment là, est initié par des facteurs eux aussi inconnus. Nos connaissances du rôle des facteurs de l'environnement sur la vie des stades parasites juvéniles et adultes sont très limitées. Chez Entobdella soleae, parasite cutané de la Sole, il existe une réponse comportementale au changement de concentration d'oxygène ; chez l'adulte d'Encotyllabe caballeroi, chez qui des yeux se développent chez les post-larves, une réponse nette à la lumière existe. Les yeux persistants que l'on trouve chez d'autres Monogènes adultes, doivent avoir un rôle plus subtil dans le comportement. Le courant d'eau peut influencer le choix du site de fixation ou le développement dissymétrique du hapteur chez les Polyopisthocotylea, mais chez Entobdella soleae, parasite cutané, c'est le premier contact, et non une réponse au courant d'eau qui est déterminant dans l'orientation, la locomotion et éventuellement la migration. Ce contact est aussi certainement important dans la locomotion de certains parasites branchiaux comme Tetraonchus monenteron. L'attraction par des phéromones n'a pas été démontrée chez les Monogènes et l'environnement turbulent de la plupart d'entre eux rend ce mode de communication peu adapté. Cependant, les relations particulières entre E. soleae et son hôte poisson plat procurent une situation où ce phénomène serait possible et avantageux. Bien que les hormones des hôtes apparaissent jouer un rôle dans la biologie de la reproduction des hématophages comme les Polystomes, la démonstration exp

Clinical research professionals are faced with decreased funding and increased workloads; innovative methods of professional development programs are necessary to accommodate these factors. This study evaluated the feasibility, perceived satisfaction, and value of using webinars to educate clinical research professionals on reporting adverse events commonly experienced in pediatric oncology clinical trials. The setting incorporated synchronous web-based educational technology. Constructivist learning provides the theoretical framework for this study. Participants evaluated the professional development program at 2 time points: (a) at the conclusion and (b) 4 to 6 weeks afterward, using survey method. Synchronous webinars were both economical and effective in educating clinical research professionals across institutional sites. Participants reported exceptionally high levels of satisfaction with the accessibility, scope, quality, and interactivity of the professional development program. The vast majority of participants reported that the education would assist with reporting adverse events in pediatric oncology clinical trials and this perception persisted into clinical practice. Although the results of this study were intended to guide future educational efforts of the Children's Oncology Group, they may also apply to other cooperative groups.

Rôle des bactéries sulfurogènes dans la corrosion du fer Involvment of Sulfidogenic Bacteria in Iron Corrosion

2006-12-01

Full Text Available Cet article fait le point sur les connaissances concernant l'implication des bactéries sulfurogènes dans la corrosion des aciers au carbone. Après la description de quelques cas récents tirés de l'industrie pétrolière, la physiologie des bactéries sulfurogènes qui jouent le rôle principal dans le mécanisme de la corrosion anaérobie d'origine bactérienne est examinée. La participation des bactéries productrices d'H2S à la constitution de biofilms est une condition importante à la manifestation des phénomènes de corrosion. Les différentes hypothèses de mécanismes décrites par la littérature sont passées en revue. Indépendamment du rôle physicochirnique joué par les sulfures de fer, non couvrants, bons conducteurs électriques, il en ressort que l'acidification résultant du métabolisme cellulaire est un facteur crucial, non seulement en termes d'électrochimie, mais également en termes de croissance microbienne. L'acidification métabolique explique vraisemblablement la fourniture des ions ferreux pour le micro-organisme dans un environnement chargé d'ions sulfures et finalement la persistance de son activité physiologique dans un micro environnement riche en H2S. The involvement of sulfidogenic bacteria in the corrosion of carbon steel is reviewed. After a brief description of some recent cases drawn from the petroleum industry, the physiology of the sulfidogenic bacteria which plays the most important role in the mechanism of anaerobic bacterial corrosion is examined. The involvement of H2S-producing bacteria to the biofilm formation is a prerequisite for biocorrosion. The hypothetical mechanisms described in the literature are reviewed. Regardless of the physicochemical role played by iron sulfides, which have been shown to be non-covering and to have good properties of electric conductivity, the acidification arising from cellular metabolism has been found to be an important parameter, not only in terms of

Full Text Available This paper presents the results of asphaltene precipitation and deposition during lean gas injection, CO2 injection and natural depletion in reservoir conditions. In addition, the effect of variations in operating pressure, injection gas concentration and production rate on asphaltene precipitation and deposition were investigated. The severity of asphaltene deposition was found to be more pronounced in lean gas injection in comparison with CO2 injection and natural depletion. Increasing the flow rate in natural depletion experiments showed a considerable increase in asphaltene deposition, and consequently permeability reduction in the core matrix. Moreover, more asphaltene deposition was observed along the porous media in the gas injection experiments when the gas mol percent of the mixture was increased. Cet article présente les résultats d’une étude de la précipitation et du dépôt d’asphaltènes qui peuvent se produire lors d’une injection de gaz pauvre, d’une injection de CO2 ou d’une déplétion naturelle en conditions de réservoir. En outre, les effets de la pression de fonctionnement, de la concentration en gaz injecté et du débit de production sur la précipitation et le dépôt d’asphaltènes ont été étudiés. Il a été constaté que l’importance du dépôt d’asphaltènes est plus prononcée dans le cas d’une injection de gaz pauvre comparativement à une injection de CO2 ou à une déplétion naturelle. Une augmentation du débit au cours d’expériences de déplétion naturelle a montré un accroissement considérable du dépôt d’asphaltènes et, en conséquence, une réduction de perméabilité au sein de la matrice poreuse. Par ailleurs, un dépôt d’asphaltènes plus important a été observé au cours des expériences d’injection de gaz lorsque la concentration molaire gazeuse dans le mélange était augmentée.

Stripple, Haakan; Uppenberg, Stefan

2010-09-15

Environmental aspects are today highly important issues in the transport sector especially from a society perspective. Most likely, our society is facing considerable changes in the transport sector due to changes in the energy/environmental situation in the future. Strategic decisions concerning the development of the transport sector must be based on solid facts concerning both the transport infrastructure and the transport traffic on the infrastructure. The transport infrastructure is often complex and difficult to analyse but of great interest in a society perspective. In this project, we have performed a comprehensive view of a modern railway infrastructure system including the traffic on the infrastructure. A Life Cycle Assessment (LCA) methodology has been used for the study and several LCA models of the railway system have been designed. Due to the complexity of the models, several general railway component models have been developed. The component models can then be integrated to form a large model of an entire railway system. The component models (sub-models) are: 'Railway track foundation model', 'Railway track model', 'Railway electric power and control system model', 'Railway tunnel model', 'Railway bridge model', 'Railway passenger station and freight terminal model', 'Passenger and freight train model including train operation'. The LCA models have then been used to analyse the environmental performance of the Bothnia Line and to develop Environmental Product Declarations (EPDs) for the Bothnia Line

In all cases, microemulsions are depicted with the occurrence of Winsor type systems, WI, WII and WIll. Remarkable variations in the diagrams are observed with molecular structural changes of zwitterionic amphiphiles. Interionic distances effects are obtained in the WI and WIll phases, suggesting a polar head surface change, while the HLB factor implies the appearance of differently ordered structures. The nature of the substituent covalently bonded on phosphorus can be used as a molecular probe to check the hydrophilicity of amphionics. Analyses of phases behaviors under various salinity and temperature conditions are also described, and attempts are made to rationalize these variations through the molecular parameters of the surfactants. On the basis of these results, an analysis can be made to optimize the structural parameters of surfactants for use as additives in tertiary oil-recovery processes.

In the present investigation, the three composite powders were prepared by sol–gel synthesis and its phase purity was analyzed by Powder X-ray diffraction (XRD method. Further, the performance of the deposited coatings was assessed by scanning electron microscopy (SEM coupled with energy dispersive X-ray analysis (EDAX, scratch resistance test. The electrochemical properties of the composite coatings were analyzed by Potentiodynamic (Tafel polarization and electrochemical impedance spectroscopy (EIS studies. From the results, we observed that the corrosion resistance behavior of the different composite coated metallic substrate exhibited divergent corrosion resistance nature than blank Ti–6Al–4V. Of all these coatings on Ti–6Al–4V, the composite made up of, ZrO2/TiO2 has pronounced corrosion resistance behavior in Ringer’s solution when compared to others. This behavior is due to the presence of strong adherent coating owing to the existence of uniform deposition on Ti–6Al–4V.

Composite coatings of Hydroxyapatite (HA) with ceramics, polymers and metals are used to modify the surface structure of implants. In this research, HA/TiO2 composite coating was fabricated by electrophoretic deposition (EPD) on 316 stainless steel substrate. HA/TiO2 composite coatings with 5, 10 and 20 wt.% of TiO2, deposited at 40 V and 90 s as an optimum condition. The samples coated at this condition led to an adherent, continuous and crack-free coating. The influence of TiO2 content was studied by performing different characterization methods such as scanning electron microscopy (SEM), energy dispersive x-ray spectroscopy (EDS), corrosion resistance in simulated body fluid (SBF), coating's dissolution rate in physiological solution and bond strength to the substrate. The results showed that the higher amount of TiO2 in the composite coating led to increase in bond strength of coating to stainless steel substrate from 3 MPa for HA coating to 5.5 MPa for HA-20 wt.% TiO2 composite coating. In addition, it caused to reduction of corrosion current density of samples in the SBF solution from 18.92 μA/cm2 for HA coating to 6.35 μA/cm2 for HA-20 wt.% TiO2 composite coating.

In addition, it caused to reduction of corrosion current density of samples in the SBF solution from 18.92 μA/cm2 for HA coating to 6.35 μA/cm2 for HA-20 wt.% TiO2 composite coating.

OBJECTIVE: To evaluate the accuracy of the Edinburgh Postnatal Depression Scale (EPDS) and 3 subscales for identifying postpartum depression among primiparous adolescent mothers. METHODS: Mothers enrolled in a randomized controlled trial to prevent postpartum depression completed a psychiatric diagnostic interview and the 10-item EPDS at 6 weeks, 3 months, and 6 months postpartum. Three subscales of the EPDS were assessed as brief screening tools: 3-item anxiety subscale (EPDS-3), 7-item depressive symptoms subscale (EPDS-7), and 2-item subscale (EPDS-2) that resemble the Patient Health Questionnaire-2. Receiver operating characteristic curves and the areas under the curves for each tool were compared to assess accuracy. The sensitivities and specificities of each screening tool were calculated in comparison with diagnostic criteria for a major depressive disorder. Repeated-measures longitudinal analytical techniques were used. RESULTS: A total of 106 women contributed 289 postpartum visits; 18% of the women met criteria for incident postpartum depression by psychiatric diagnostic interview. When used as continuous measures, the full EPDS, EPDS-7, and EPDS-2 performed equally well (area under the curve >0.9). Optimal cutoff scores for a positive depression screen for the EPDS and EPDS-7 were lower (≥9 and ≥7, respectively) than currently recommended cutoff scores (≥10). At optimal cutoff scores, the EPDS and EPDS-7 both had sensitivities of 90% and specificities of >85%. CONCLUSIONS: The EPDS, EPDS-7, and EPDS-2 are highly accurate at identifying postpartum depression among adolescent mothers. In primary care pediatric settings, the EPDS and its shorter subscales have potential for use as effective depression screening tools. PMID:24344102

Le droit étatique mexicain et les populations indigènes : fonction de reconnaissance ou fonction d’intégration Mexican State law and indigenous populations: recognition function or integration function

Full Text Available L’articulation de l’État, du droit et de la réalité indigène au Mexique pose le problème de la reconnaissance. La reconnaissance de populations indigènes qui se distinguent du reste de la population mexicaine mais qui aspirent à être incluses de plein droit dans une notion d’État forcément renouvelée. En effet, le cadre constitutionnel mexicain accorde difficilement une place aux populations indigènes et reflète le tiraillement entre une conception unitaire de l’État et du droit étatique et une réalité multiculturelle de plus en plus présente et exigeante d’une inclusion explicite de la diversité. Le droit étatique est perçu comme un lieu privilégié de reconnaissance, il est également perçu comme un instrument de revendication. Pour les populations indigènes, le droit positif peut opérer la réconciliation, cependant ce droit étatique semble bel et bien avoir des limites face aux attentes légitimes d’un secteur important de la population.The way in which the State, the Law and the indigenous reality are articulated in Mexico involves the question of their recognition; the recognition of indigenous people, who are different in certain aspects from the rest of the population, but who want to be included with full rights in a definition of the State that has to be renewed. As a matter of fact, Mexican Constitution does not completely grant a place to indigenous people, this a document does not solve the tension between a unitary conception of the State and State law, and a multicultural reality that actually demands a bigger and more explicit recognition. State Law is seen by indigenous people as the main instrument of recognition, and it is also seen as a vindication instrument; they are looking for their recognition, they try to get it and to achieve reconciliation through the law. However, State law seems to have serious limits when faced with the rightful expectations of this important part of population.

2008-01-01

To describe the stability of radiation survey meters (RSMs) and electronic pocket dosemeters (EPDs), we examined 28 EPDs and 24 RSMs: 12 used NaI(Tl) scintillation RSMs and 12 used Geiger-Muller (GM) RSMs. We used simple methods for the relative calibration of the 24 RSMs and 28 EPDs. The RSM and EPD measurements were compared with a calibrated RSM and EPD (reference: traceable from the national standard of exposure) using a homemade measurement device to maintain the reproducibility of the measurements with reference radiation sources (i.e. 137 Cs, 90 Sr and 67 Ga). The response of RSMs and EPDs, especially after prolonged use, should be checked periodically. In particular, GMRSMs that have been in use for many years have very low sensitivity and poor reproducibility. Our simple method for the relative calibration of RSMs and EPDs was shown to be effective for quality assurance purposes in checking RSMs and EPDs. We recommend regular checks and calibration for sustained performance of RSMs and EPDs. (authors)

Chávez-Valdez, Alejandra; Boccaccini, Aldo R.

2012-01-01

This review summarizes emerging developments in the field of alternating current (AC) and pulsed direct current (DC) electrophoretic deposition (EPD) in aqueous or organic media. Numerous applications of AC-EPD are discussed including two major groups of investigations: (i) AC-EPD to suppress water hydrolysis at high voltages in inorganic (ceramic) coatings and (ii) AC-EPD for deposition of biological entities. The deposition, purification and manipulation of carbon nanotubes and nanoparticles by AC-EPD to form specific arrays, for development of sensors and other electronic devices and the application of AC-EPD as method for separation of particles according to their shape or size are also presented. Other applications reviewed relate to the fabrication by AC-EPD of toxic gas sensors from oxides and superconducting layers. The main materials being examined by AC-EPD are inorganic, including carbon nanotubes, TiO 2 nanoparticles, Al 2 O 3 , Si, SnO 2 , ZnO and WO 3 and biological entities, e.g. bacteria cells. For pulsed EPD, the applications reviewed are divided in pulsed current and pulsed voltage EPD. Among the applications of pulsed EPD, the formation of thick films from aqueous suspensions without water decomposition, the fabrication of multilayer and composite materials and the size-selective deposition of ceramic nanoparticles are the most important investigated to date, based on the quality of the coatings and deposits obtained and their relevance for applications.

Colbach Nathalie

2000-07-01

Full Text Available On a beaucoup parlé, lors de l’examen des demandes d’autorisation de mise en culture de variétés transgéniques de colza, des risques d’hybridation interspécifique du colza avec les crucifères sauvages, et d’introgression de transgènes dans les espèces adventices [1, 2]. Les flux de gènes intraspécifiques ont moins attiré l’attention du grand public; ils sont pourtant bien plus probables. Les transgènes peuvent être disséminés dans le temps, par l’intermédiaire de repousses de colza apparaissant dans les cultures suivant les variétés transgéniques, à cause de la perte d’une partie des graines produites par les cultures de colza avant ou pendant la récolte [3, 4], et dans l’espace, par l’intermédiaire de semences et de pollen disséminés par le vent ou d’autres vecteurs tels que les oiseaux ou les insectes [5-8]. Les semences dispersées peuvent produire directement des repousses de colza dans des champs voisins, tandis que le pollen peut transmettre le transgène en fécondant des plantes de colza présentes dans ces autres champs. Ce flux de gènes peut être à l’origine de différents problèmes tels que l’apparition de repousses de colza résistantes aux herbicides, difficiles à éliminer lorsqu’il s’agit d’un transgène de résistance à un herbicide, ou la pollution de récoltes de colza classique par le transgène, quelle que soit sa nature, et l’impossibilité d’écouler ces récoltes dans une filière « non-OGM ». Il est donc apparu nécessaire et urgent de mieux évaluer ce risque et d’identifier les moyens de le maîtriser. Les premiers éléments de réponse ont été donnés par les plates-formes « plantes transgéniques » des instituts techniques [9, 10]; cependant, ces plates-formes sont limitées dans le temps et l’espace et il n’est pas possible d’y rendre compte de la variabilité régionale des systèmes de culture et de leurs effets sur le devenir des

2018-04-01

In this study, we developed an autodetection technique for the equatorial plasma depletions (EPDs) and their occurrence and depletion amplitudes based on in situ electron density measurements gathered by Swarm A satellite. For the first time, comparisons are made among the detected EPDs and their amplitudes with the loss of Global Positioning System (GPS) signal of receivers onboard Swarm A, and the Swarm Level-2 product, Ionospheric Bubble Index (IBI). It has been found that the highest rate of EPD occurrence takes place generally between 2200 and 0000 magnetic local time (MLT), in agreement with the IBI. However, the largest amplitudes of EPD are detected earlier at about 1900-2100 MLT. This coincides with the moment of higher background electron density and the largest occurrence of GPS signal loss. From a longitudinal perspective, the higher depletion amplitude is always witnessed in spatial bins with higher background electron density. At most longitudes, the occurrence rate of postmidnight EPDs is reduced compared to premidnight ones; while more postmidnight EPDs are observed at African longitudes. CHAMP observations confirm this point regardless of high or low solar activity condition. Further by comparing with previous studies and the plasma vertical drift velocity from ROCSAT-1, we suggest that while the F region vertical plasma drift plays a key role in dominating the occurrence of EPDs during premidnight hours, the postmidnight EPDs are the combined results from the continuing of former EPDs and newborn EPDs, especially during June solstice. And these newborn EPDs during postmidnight hours seem to be less related to the plasma vertical drift.

Predictability of summer extreme precipitation days over eastern China

Li, Juan; Wang, Bin

2017-08-01

Extreme precipitation events have severe impacts on human activity and natural environment, but prediction of extreme precipitation events remains a considerable challenge. The present study aims to explore the sources of predictability and to estimate the predictability of the summer extreme precipitation days (EPDs) over eastern China. Based on the region- and season-dependent variability of EPDs, all stations over eastern China are divided into two domains: South China (SC) and northern China (NC). Two domain-averaged EPDs indices during their local high EPDs seasons (May-June for SC and July-August for NC) are therefore defined. The simultaneous lower boundary anomalies associated with each EPDs index are examined, and we find: (a) the increased EPDs over SC are related to a rapid decaying El Nino and controlled by Philippine Sea anticyclone anomalies in May-June; (b) the increased EPDs over NC are accompanied by a developing La Nina and anomalous zonal sea level pressure contrast between the western North Pacific subtropical high and East Asian low in July-August. Tracking back the origins of these boundary anomalies, one or two physically meaningful predictors are detected for each regional EPDs index. The causative relationships between the predictors and the corresponding EPDs over each region are discussed using lead-lag correlation analyses. Using these selected predictors, a set of Physics-based Empirical models is derived. The 13-year (2001-2013) independent forecast shows significant temporal correlation skills of 0.60 and 0.74 for the EPDs index of SC and NC, respectively, providing an estimation of the predictability for summer EPDs over eastern China.

People with cognitive disabilities have difficulties in accomplishing everyday tasks. Electronic planning devices (EPDs) may compensate for the gap between a person's capacity and everyday challenges. However, the devices are not always used as intended. Despite that, cognitive assistive technology has been investigated in several studies, knowledge regarding when and what makes adults decide to use EPDs is incomplete. The aim was to explore the subjective experiences of people with cognitive disabilities in relation to the use of EPDs. A qualitative approach was applied with a qualitative content analysis. Twelve respondents were interviewed with support from a study specific guide. A model representing the respondents' experiences in the use of EPDs, comprising one theme, Possibility to master my daily life, four categories, Degree of fit to my needs, I am aware of my cognitive disability, I get help to structure my everyday life and The EPD improves my volition and ten subcategories, was developed. EPDs allow people with cognitive disabilities the possibility to deal with daily challenges; those who find EPDs beneficial tend to use them. EPDs can help people with cognitive disabilities in organisation, managing time and improve volition.

The tight junction protein Z O-2 has several functional nuclear export signals

International Nuclear Information System (INIS)

Gonzalez-Mariscal, Lorenza; Ponce, Arturo; Alarcon, Lourdes; Jaramillo, Blanca Estela

2006-01-01

The tight junction (TJ) protein ZO-2 changes its subcellular distribution according to the state of confluency of the culture. Thus in confluent monolayers, it localizes at the TJ region whereas in sparse cultures it concentrates at the nucleus. The canine sequence of ZO-2 displays four putative nuclear export signals (NES), two at the second PDZ domain (NES-0 and NES-1) and the rest at the GK region (NES-2 and NES-3). The functionality of NES-0 and NES-3 was unknown, hence here we have explored it with a nuclear export assay, injecting into the nucleus of MDCK cells peptides corresponding to the ZO-2 NES sequences chemically coupled to ovalbumin. We show that both NES-0 and NES-3 are functional and sensitive to leptomycin B. We also demonstrate that NES-1, previously characterized as a non functional NES, is rendered capable of nuclear export upon the acquisition of a negative charge at its Ser369 residue. Experiments performed injecting at the nucleus WT and mutated ZO-2-GST fusion proteins revealed the need of both NES-0 and NES-1, and NES-2 and NES-3 for attaining an efficient nuclear exit of the respective amino and middle segments of ZO-2. Moreover, the transfection of MDCK cells with full-length ZO-2 revealed that the mutation of any of the NES present in the molecule was sufficient to induce nuclear accumulation of the protein

The American Society for Microbiology (ASM) has a history of providing a wide range of faculty development opportunities. Recently, ASM developed the Science Teaching Fellows Program (STF) for early career biologists and postdoctoral students to explore student-centered teaching and develop the skills needed to succeed in positions that have a significant teaching component. Participants were selected to STF through a competitive application process. The STF program consisted of a series of six webinars. In preparation for each webinar, participants completed a pre-webinar assignment. After each webinar, fellows practiced what they learned by completing a post-webinar assignment. In a survey used to assess the impact of STF, participants reported greater knowledge of the webinar-based instructional topics and a sense of being part of an educational community and were more confident about varied teaching methods.

A new way of controlling NesCOPOs (nested cavity doubly resonant OPO) for faster and more efficient high resolution spectrum measurement

Science.gov (United States)

2018-02-01

Optical Parametric Oscillator (OPO) is a well-known solution when wide tunability in the mid-infrared is needed. A specific design called NesCOPO (Nested Cavity doubly resonant OPO) is currently integrated in the X-FLR8 portable gas analyzer from Blue Industry and Science. Thanks to its low threshold this OPO can be pumped by a micro-chip nanosecond YAG (4 kHz repetition rate and a 30 GHz bandwidth). To achieve very high resolution spectra (10 pm of resolution or better), the emitted wavelength has to be finely controlled. Commercial Wavemeter do not meet price and compactness required in the context of an affordable and portable gas analyzer. To overcome this issue, Blue first integrated an active wavelength controller using multiple tunable Fabry-Perot (FP) interferometers. The required resolution was achieved at a 10 Hz measurement rate. We now present an enhanced Wavemeter architecture, based on fixed FP etalons, that is 100 times faster and 2 times smaller. We avoid having FP `blind zones' thanks to one source characteristic: the knowledge of the FSR (Free Spectral Range) of the OPO source and thus, the fact that only discrete wavelengths can be emitted. First results are displayed showing faster measurement for spectroscopic application, and potential future improvement of the device are discussed.

Factor structure of the Japanese version of the Edinburgh Postnatal Depression Scale in the postpartum period.

Directory of Open Access Journals (Sweden)

Chika Kubota

Full Text Available BACKGROUND: The Edinburgh Postnatal Depression Scale (EPDS is a widely used screening tool for postpartum depression (PPD. Although the reliability and validity of EPDS in Japanese has been confirmed and the prevalence of PPD is found to be about the same as Western countries, the factor structure of the Japanese version of EPDS has not been elucidated yet. METHODS: 690 Japanese mothers completed all items of the EPDS at 1 month postpartum. We divided them randomly into two sample sets. The first sample set (n = 345 was used for exploratory factor analysis, and the second sample set was used (n = 345 for confirmatory factor analysis. RESULTS: The result of exploratory factor analysis indicated a three-factor model consisting of anxiety, depression and anhedonia. The results of confirmatory factor analysis suggested that the anxiety and anhedonia factors existed for EPDS in a sample of Japanese women at 1 month postpartum. The depression factor varies by the models of acceptable fit. CONCLUSIONS: We examined EPDS scores. As a result, "anxiety" and "anhedonia" exist for EPDS among postpartum women in Japan as already reported in Western countries. Cross-cultural research is needed for future research.

1996-01-01

The aim of this study was to evaluate the efficacy and safety of enzyme-potentiated desensitization (EPD) in children with asthma. Twenty asthmatic children (14 males and 6 females; median age: 8.5 years) were included in the study. They had positive skin tests to Dermatophagoides pteronyssinus (Dpt), no history of other allergy and had suffered from asthma for at least two years. The children were examined before starting the trial, at the first EPD dose, after 8 weeks, at the second EPD dose and 3 months after the second EPD dose. Blood samples for PRIST and RAST were drawn before the first and at the second EPD dose, and at the last follow-up. Conjunctival provocation tests (CPT) and skin test endpoint determinations were performed with dilutions of a freeze-dried Dpt extract (10-100,000 SQ-U/ml) at the start of the trial and at the last follow-up. Parents kept a diary record of the days with asthma and daily drug usage. The children were randomized to receive either two intradermal placebo injections or the active material with an 8-week interval (November 1991 and January 1992). Ten children received EPD and 10 children placebo. The intradermal injection of EPD (0.05 ml) contained 0.01 ml of beta-glucuronidase (40 Fishman units) and 0.04 ml of a mixture of inhalant allergens (1 Noon unit). The placebo injection consisted of buffer solution only. The EPD-treated children had significantly fewer days with asthma (p = 0.00000). In addition, the EPD-treated children used significantly less medication for the management of asthma attacks (p = 0.00000). At the start of the trial, three out of 10 children in the EPD group and two out of 10 in the placebo group reacted only to the highest dose of allergen used in the CPT (100,000 SQ/ml) (NS). At the last follow-up, the threshold dose in the CPT was 100,000 SQ/ml or more in nine out of 10 children in the EPD group and in four out of 10 children of the placebo group (p = 0.0349). At the last follow-up, one child in the

Modélisation de la combustion de fuels lourds prenant en compte la dispersion des asphaltènes Modeling Heavy Fuel-Oil Combustion (While Considering Or Including Asphaltene Dispersion

Directory of Open Access Journals (Sweden)

Full Text Available Divers modèles, ayant pour but de prédire le taux d'imbrûlés solides lors de la combustion du fuel lourd, ont été mis au point dans le passé. Les paramètres entrant en ligne de compte sont le plus souvent les teneurs en résidus lourds hydrocarbonés (asphaltènes précipités au pentane ou à l'heptane et carbone Conradson et en métaux : c'est le cas des modèles Exxon et Shell développés respectivement en 1979 et 1981. D'autres modèles tiennent compte, en plus de la composition du fuel, de son mode d'atomisation, de son mode de diffusion dans le foyer et de la cinétique de combustion : on peut citer les travaux du Laboratoire Energie du MIT publiés en 1986. Néanmoins, ces facteurs ne sont pas les seuls à intervenir : l'expérience a montré que l'état de dispersion des asphaltènes peut jouer également un grand rôle, notamment dans le cas d'installations de combustion à injection mécanique, pour lesquelles la dispersion des gouttelettes n'est pas aussi fine que pour des installations munies d'une injection assistée par la vapeur. Cette influence de la dispersion des asphaltènes sur la combustion a été mise en évidence dans le passé par l'utilisation d'additifs dispersants et également par la combustion de fuels lourds constitués par dilution d'asphaltes précipités au pentane avec un gas-oil de cracking catalytique de raffinerie (LCO. Ce sont ces fuels que l'on a considérés dans la présente étude. L'effet de ce facteur dispersion n'a pas été quantifié jusqu'alors, la difficulté étant de définir une grandeur mesurable représentant la répartition des agglomérats d'asphaltènes. Dans cette étude, on a essayé en un premier temps de faire une approche fractale de la répartition des asphaltènes à partir de clichés (préparés par la société Total, cette méthode ayant déjà été utilisée avec succès pour décrire des structures d'aspects comparables. Malheureusement, on s'est heurté à des

High frequency electromagnetic fields emitted from digital cellular telephones (cell phones) occasionally cause abnormally high values (wrong dosages) on electronic pocket dosimeters (EPD). Electric field strength distribution around the cell phone transmitting 1.5GHz band with a maximum power of 0.8 W was analyzed by using an isotropic probe with tri-axial dipole antennas. Five kinds of EPDs were exposed to the fields for 50s under four kinds of configurations relative to the cell phone. The electric field distribution expanded around the antenna and had a maximum strength level of 36.5 {+-} 0.30 V/m. The cell phone gave rise to a wrong dosage of four EPDs out of five. The electromagnetic susceptibility of the EPD was higher in the section where the semiconductor detector or electric circuit boards were implanted. The maximum value of wrong dosage was 1283{mu} Sv. The distance preventing electromagnetic interference differed in each EPD and ranged from 2.0cm to 21.0cm. The electromagnetic immunity levels of the EPDs were distributed from 9.2V/m to a value greater than 35V/m. The EPDs displayed wrong dosage during exposure, while they recovered their normal performance after the cell phone ceased transmitting. The electromagnetic immunity levels of the EPDs were either equal to or greater than the IEC-standard. The immunity levels should be enhanced greater than the IEC-standard from the standpoint of radiation protection.

Electric field strength distribution around the digital cellular telephone (cell phone) transmitting 1.5GHz band was analyzed by using an isotropic probe. Five types of electronic pocket dosimeters (EPDs) were exposed to the fields for 50sec under four kinds of configurations relative to the cell phone. The field distribution expanded around the antenna and had a maximum strength level of 36.5±0.3V/m. The cell phone caused abnormally high values (wrong dosages) to four EPDs out of five due to electromagnetic interference. Three out of the four EPDs exceeded the upper limits of dose range depending on the configurations, and the maximum value of wrong dosage among the EPDs was 1,283 μSv. The minimum distance preventing electromagnetic interference (protection distance) differed with each EPD and ranged from 2.0cm to 21.0cm. The electromagnetic immunity levels of EPD-1, 2, 3, 4 and 5 were 13.3, ≥35, ≥32, 9.2 and ≥35 V/m, respectively. Although the immunity levels were either equal to or greater than the IEC-standard level, those of the EPDs should be enhanced greater than the IEC-standard from the standpoint of radiation protection.

Esophageal transit scintigraphy (ETS) and esophagography have long been used to evaluate patients with achalasia. The objectives of our study were to evaluate the efficacy of endoscopic pneumatic dilatation (EPD) as treatment for Koreans with achalasia and to determine which findings from ETS and esophagography predict successful treatment of achalasia. Patients with achalasia who were treated by EPD between April 2002 and January 2012 were recruited. We defined the success of EPD as 6 months or more of clinical remission without symptoms or a decrease in the Eckardt scores by at least two points and a total Eckardt score not exceeding 3. We reviewed the percentage of maximum scintigraphic activity retained in the esophagus at 30 s (R 30) and the post-PD rate of reduction of R 30 ((Pre R 30 - Post R 30)/Pre R 30 × 100) by ETS. Possible predictive factors determined by ETS and esophagography were analyzed. Our study included 53 eligible patients. The median symptom score (Eckardt score) was 5 (4-8). R 30 and T 1/2 were, respectively, 61.8 % and 38.5 min before EPD and 20 % and 4.19 min after EPD. Successful EPD was achieved for 40 of 53 (75.47 %) patients. Age (≥40, p = 0.027) and post-PD rate of reduction of R 30 (>20 %, p = 0.003) were best prognostic indicators of clinical success. There were no perforations related to EPD. Older age and a post-PD rate of reduction of R 30 were strongly associated with better outcomes. Examination with ETS before and after EPD can be used to objectively assess a patient's short-term response to EPD.

To describe daily time management in adults with and without mental disability and to examine differences in the level of their daily time management; to describe the possessions and use of electronic planning devices (EPDs) in activities and how environmental factors influence the use of EPDs in adults with mental disability. In a descriptive and cross-sectional design, 32 participants using EPDs and a matched comparison group of 32 healthy adults was recruited. Time-Self rating scale measuring daily time management was adapted for adults. A study specific questionnaire was applied to collect data on five ICF environmental factors. Rasch modelling, descriptive and non-parametric statistics were applied. Time-S has acceptable psychometric properties for use on adults with mental disability. People with mental disability and low level of daily time management who use advanced EPDs are more influenced by environmental factors. The study group perceived that encouragement and support from professionals as well as services influence their use of EPDs. Time-S can safely be used for people with mental disability. EPDs do not fully compensate the needs of the target-group. Prescribers need to give considerations to this and therefore they should be provided with more knowledge about this matter. Implications for Rehabilitation The Time-S can be applied for measuring daily time management in adults. Adults with mental disability provided with EPDs are not fully compensated in daily time management. Professional support and encouragement as well as backing from the services are important factors for the use of EPDs. Because the smart phones are not prescribed as assistive technology, the need for help from professionals to facilitate daily life is stressed. Therefore, the professionals should be provided with more knowledge about the use of EPDs.

We sought to measure angiographic renal frame counts (RFC), as a quantitative angiographic assessment of renal blood flow, to evaluate microvascular compromise due to atheroembolism associated with RAS. Atheroembolism associated with renal artery stenting (RAS) has been implicated as a cause for worsening renal function following successful intervention. Use of a distal embolic protection device (EPD) during RAS has been shown to be safe with debris capture in a high percentage of cases. However, objective benefit for renal function with EPD has been difficult to demonstrate. A control group of 30 consecutive patients (33 kidneys) who underwent RAS without EPD were compared with 33 consecutive patients (33 kidneys) who underwent RAS with EPD using RFC measurement. The prestent and poststent mean RFC for the control group was 30.4 ± 12.1 vs. 23.7 ± 9.9 (P = 0.002) and for the EPD group it was 42.6 ± 12.6 vs. 28.3 ± 9.2 (P renal blood flow, manifested by a greater reduction of the RFC (Δ RFC) 14.2 ± 15.2 vs. 6.7 ± 11.7 (P = 0.03) compared with the control group. The use of an EPD was associated with a much larger improvement in renal blood flow (lower RFC) following RAS. This suggests that EPD's may be effective in preventing renal atheroembolic injury and that a controlled trial measuring the impact of EPD's on renal blood flow following RAS should be performed.

Postnatal depression affects a significant number of parents; however, its co-occurrence in mothers and fathers has not been studied extensively. Identifying predictors and correlates of postnatal depressive symptoms can help develop effective interventions. Questionnaires on several socio-demographic and psychosocial factors were administered to 276 couples within two weeks after birth. Depressive symptoms in mothers and fathers were assessed using the Edinburgh Postnatal Depression Scale (EPDS). After calculating the correlation coefficient between mothers and fathers' EPDS scores, univariate and multivariate linear regression analyses were performed to identify significant correlates of postnatal depressive symptoms in mothers and fathers. Prevalence of maternal and paternal postnatal depressive symptoms was 15.9% (EPDS>12) and 5.4% (EPDS>10), respectively. There was a moderate positive correlation between mothers and fathers' EPDS scores (r=.30, pparental stress was the strongest predictor for maternal and paternal postnatal depressive symptoms. Pregnancy- and birth-related distress and partners' EPDS scores were also associated with depressive symptoms in both parents. Relationship satisfaction was only inversely related with fathers' EPDS scores, while mothers' EPDS scores were additionally associated with critical life events, history of childhood violence, and birth-related physiological complaints. Since information about participation rates (those who declined) is unavailable, we cannot rule out sampling bias. Further, some psychosocial factors were assessed using single items. Since co-occurrence of depressive symptoms in mothers and fathers is high, developing and evaluating postnatal depression interventions for couples may be beneficial. Interventions to reduce parenting stress may help prevent parental postnatal depression. Copyright © 2015 Elsevier B.V. All rights reserved.

Feasibility of the electrophoresis deposition (EPD) technique for homogeneous and adhesive deposition of DyF3 particles on the Nd-Fe-B-type particles was studied, and coercivity enhancement in the diffusion-treated Nd-Fe-B-type particles deposited with DyF3 by EPD was investigated. HDDR-treated Nd12.5Fe80.6B6.4Ga0.3Nb0.2 particles were deposited with DyF3 particles by EPD. More homogeneous and adhesive deposition of DyF3 particles on the surface of Nd-Fe-B particles was made by the EPD with respect to conventional dip-coating, and this led to more active and homogeneous diffusion of Dy. More profound coercivity enhancement was achieved in the diffusion-treated Nd-Fe-B-type particles deposited with DyF3 by EPD compared to dip-coated particles.

Baicalein (BCL) possesses high pharmacological activities but low solubility and stability in the intestinal tract. This study aimed to probe the potential of nanoemulsions (NEs) consisting of hemp oil and less surfactants in ameliorating the oral bioavailability of BCL. BCL-loaded NEs (BCL-NEs) were prepared by high-pressure homogenization technique to reduce the amount of surfactants. BCL-NEs were characterized by particle size, entrapment efficiency (EE), in vitro drug release, and morphology. Bioavailability was studied in Sprague-Dawley rats following oral administration of BCL suspensions, BCL conventional emulsions, and BCL-NEs. The obtained NEs were ~90 nm in particle size with an EE of 99.31%. BCL-NEs significantly enhanced the oral bioavailability of BCL, up to 524.7% and 242.1% relative to the suspensions and conventional emulsions, respectively. BCL-NEs exhibited excellent intestinal permeability and transcellular transport ability. The cytotoxicity of BCL-NEs was documented to be low and acceptable for oral purpose. Our findings suggest that such novel NEs and preparative process provide a promising alternative to current formulation technologies and suitable for oral delivery of drugs with bioavailability issues.

Evaluation of the Edinburgh Post Natal Depression Scale using Rasch analysis

2006-01-01

Background The Edinburgh Postnatal Depression Scale (EPDS) is a 10 item self-rating post-natal depression scale which has seen widespread use in epidemiological and clinical studies. Concern has been raised over the validity of the EPDS as a single summed scale, with suggestions that it measures two separate aspects, one of depressive feelings, the other of anxiety. Methods As part of a larger cross-sectional study conducted in Melbourne, Australia, a community sample (324 women, ranging in age from 18 to 44 years: mean = 32 yrs, SD = 4.6), was obtained by inviting primiparous women to participate voluntarily in this study. Data from the EPDS were fitted to the Rasch measurement model and tested for appropriate category ordering, for item bias through Differential Item Functioning (DIF) analysis, and for unidimensionality through tests of the assumption of local independence. Results Rasch analysis of the data from the ten item scale initially demonstrated a lack of fit to the model with a significant Item-Trait Interaction total chi-square (chi Square = 82.8, df = 40; p < .001). Removal of two items (items 7 and 8) resulted in a non-significant Item-Trait Interaction total chi-square with a residual mean value for items of -0.467 with a standard deviation of 0.850, showing fit to the model. No DIF existed in the final 8-item scale (EPDS-8) and all items showed fit to model expectations. Principal Components Analysis of the residuals supported the local independence assumption, and unidimensionality of the revised EPDS-8 scale. Revised cut points were identified for EPDS-8 to maintain the case identification of the original scale. Conclusion The results of this study suggest that EPDS, in its original 10 item form, is not a viable scale for the unidimensional measurement of depression. Rasch analysis suggests that a revised eight item version (EPDS-8) would provide a more psychometrically robust scale. The revised cut points of 7/8 and 9/10 for the EPDS-8 show high

The Edinburgh Postnatal Depression Scale (EPDS) may not be a uniformly valid postnatal depression (PND) screen across populations. We evaluated the performance of a Chinese translation of 10-item (HK-EPDS) and six-item (HK-EPDS-6) versions in post-partum women in Singapore. Chinese-speaking post-partum obstetric clinic patients were recruited for this study. They completed the HK-EPDS, from which we derived the six-item HK-EPDS-6. All women were clinically assessed for PND based on Diagnostic and Statistical Manual, Fourth Edition-Text Revision criteria. Receiver-operator curve (ROC) analyses and likelihood ratio computations informed scale cutoff choices. Clinical fitness was judged by thresholds for internal consistency [α ≥ 0.70] and for diagnostic performance by true-positive rate (>85%), false-positive rate (≤10%), positive likelihood ratio (>1), negative likelihood ratio (internal consistency was 0.84. At 13 or more cutoff, the true-positive rate was 86.7%, false-positive rate 3.3%, positive likelihood ratio 26.4, negative likelihood ratio 0.14, AUC 94.4% and effect size 0.81. For the HK-EPDS-6, internal consistency was 0.76. At 8 or more cutoff, we found a true-positive rate of 86.7%, false-positive rate 6.6%, positive likelihood ratio 13.2, negative likelihood ration 0.14, AUC 92.9% and effect size 0.98. The HK-EPDS (cutoff ≥13) and HK-EPDS6 (cutoff ≥8) are fit for PND screening for general population post-partum women. The brief six-item version appears to be clinically suitable for quick screening in Chinese speaking women. Copyright © 2013 Wiley Publishing Asia Pty Ltd.

Understanding differences in dose-equivalents reported by passive and electronic personal dosemeters

Full text: In a number of challenging environments, clients occasionally double badge with electronic personal dosemeters (EPDs) to ensure day-to-day management of their employees personal dose-equivalent while using passive (in our case Luxel or InLight) dosemeters for monthly monitoring for approved results for dose record keeping. In some cases there have been significant differences in the cumulative doses recorded by the EPDs and the passive dosemeters. In these circumstances the passive dosemeters usually report a higher dose than the EPD by up to a factor of two, though more commonly 1.3. In this paper we describe the differences seen between EPD and passive dosemeters (in a number of countries). We then examine the possible causes for such discrepancies by comparison with published response function data available for the EPDs and Landauer dosemeters. We have undertaken a number of experiments comparing directly a number of EPDs and passive dosemeter response to a variety of energy and complex angular geometries where the two types of dosimeter have been exposed at the same time. Recommendations will be made on the appropriate use of double badging in difficult environments and interpretation of the results. (author)

Electronic personal dosimeters (EPDs) based on solid state detectors have widely been used but some deficiencies in their response in pulsed radiation beams have been reported. Nowadays, there is not an international standard for pulsed X-ray beams for calibration or type testing of dosimeters. Irradiation conditions for testing the response of EPDs in both the constant potential and pulsed X-ray beams were established in CDTN. Three different types of EPDs were tested in different conditions in similar ISO and IEC X-ray qualities. Results stressed the need of performing additional checks before using EPDs in constant potential or pulsed X-rays. (author)

Optimal management of night eating syndrome: challenges and solutions

Full Text Available Suat Kucukgoncu, Margaretta Midura, Cenk Tek Department of Psychiatry, Yale University, New Haven, CT, USA Abstract: Night Eating Syndrome (NES is a unique disorder characterized by a delayed pattern of food intake in which recurrent episodes of nocturnal eating and/or excessive food consumption occur after the evening meal. NES is a clinically important disorder due to its relationship to obesity, its association with other psychiatric disorders, and problems concerning sleep. However, NES often goes unrecognized by both health professionals and patients. The lack of knowledge regarding NES in clinical settings may lead to inadequate diagnoses and inappropriate treatment approaches. Therefore, the proper diagnosis of NES is the most important issue when identifying NES and providing treatment for this disorder. Clinical assessment tools such as the Night Eating Questionnaire may help health professionals working with populations vulnerable to NES. Although NES treatment studies are still in their infancy, antidepressant treatments and psychological therapies can be used for optimal management of patients with NES. Other treatment options such as melatonergic medications, light therapy, and the anticonvulsant topiramate also hold promise as future treatment options. The purpose of this review is to provide a summary of NES, including its diagnosis, comorbidities, and treatment approaches. Possible challenges addressing patients with NES and management options are also discussed. Keywords: night eating, obesity, psychiatric disorders, weight, depression

Aim: To assess the prognostic value of 64-section multidetector computed tomography (MDCT) to predict follow-up myocardial dysfunction and functional recovery after reperfusion therapy in patients with acute myocardial infarction (MI) as defined by echocardiography. Materials and methods: After reperfusion therapy for acute MI, 71 patients underwent two-phase contrast-enhanced MDCT and follow-up echocardiography. MDCT findings were compared with echocardiographic findings using kappa statistics. The areas under the receiver operating characteristic curves (AUCs) and the odds ratios (ORs) of early perfusion defects (EPD), delayed enhancement (DE), and residual perfusion defects (RPD) for predicting follow-up myocardial dysfunction and functional recovery were calculated on a segmental basis. Results: The presence of transmural EPD (EPD TM ) or RPD showed good agreement (k = 0.611 and 0.658, respectively) with follow-up myocardial dysfunction, while subendocardial EPD (EPD sub ) or subendocardial DE (DE sub ) showed fair agreement with follow-up myocardial dysfunction (k = 0.235 and 0.234, respectively). The AUC of RPD (0.796) was superior (p TM (0.761) and DE TM (0.771). The presence of EPD TM , DE TM , and RPD were significant, independent positive predictors of follow-up myocardial dysfunction (OR = 6.4, 1.9, and 9.8, respectively). EPD TM was a significant, independent negative predictor of myocardial functional recovery (OR = 0.13). Conclusion: Abnormal myocardial attenuation on two-phase MDCT after reperfusion therapy may provide promising information regarding myocardial viability in patients with acute MI.

An investigation undertaken into a sample of 1,115 five-year old children attending kindergartens in the city of Córdoba (Argentina) is described. The investigation aimed at establishing the prevalence and distribution of dental caries by socioeconomic level. Research showed that the prevalence of caries had decreased 55.0% in relation to the 1973 figure, while the proportion of children with healthy teeth was 26.7% greater. The frequency and seriousness of the caries increased as the child's social position declined. At the highest socioeconomic level NES I = entrepreneurial and managerial bourgeoisie), the rates of caries were significantly lower than those at the lowest socioeconomic level (NES III = typical proletariat, nontypical proletariat and sub-proletariat) presenting dmf-t of 0.8 and 2.7, and dmf-s of 0.9 and 4.9, respectively. In NES III, the dmf-t main components were decayed and missing teeth, while in NES I filled teeth were the main components. The proportion of children with no experience of caries was 63.1% in NES I and 11.5% in NES III. Inversly, the rate dental health was higher in NES I (8.8) than in NES III (5.1). The cost per child required for the restorative treatment in approximately two and a half times greater in NES III than in NES I. Considering the sample as a whole the expenditure required for NES III would be more than ten times higher than that required for NES I.(ABSTRACT TRUNCATED AT 250 WORDS)

Buxton, Eric C

2014-02-12

To evaluate and compare pharmacists' satisfaction with the content and learning environment of a continuing education program series offered as either synchronous or asynchronous webinars. An 8-lecture series of online presentations on the topic of new drug therapies was offered to pharmacists in synchronous and asynchronous webinar formats. Participants completed a 50-question online survey at the end of the program series to evaluate their perceptions of the distance learning experience. Eighty-two participants completed the survey instrument (41 participants from the live webinar series and 41 participants from the asynchronous webinar series.) Responses indicated that while both groups were satisfied with the program content, the asynchronous group showed greater satisfaction with many aspects of the learning environment. The synchronous and asynchronous webinar participants responded positively regarding the quality of the programming and the method of delivery, but asynchronous participants rated their experience more positively overall.

To evaluate the incidence and impact of early post-chemoradiation (cRT) 'pseudoprogression' (PsPD) amongst glioblastoma multiforme (GBM) patients treated with the current standard of care – 60 Gy conformal radiotherapy with concurrent low-dose temozolomide, followed by six cycles of high-dose temozolomide (the 'Stupp protocol'). Clinical notes and radiology reports for GBM patients treated as per the Stupp protocol were reviewed. PsPD was defined as apparent radiological progression on the first post-cRT scan, with further imaging within 3 months being stable or improving, while true early progression (ePD) was confirmed by continued progression in the subsequent 3 months following the first post-cRT scan. Of the 68 patients evaluated, 14 (21%) and 27 (40%) experienced PsPD and ePD, respectively; 3/14 (21%) patients experiencing PsPD and 14/27(52%), ePD were symptomatic for progression on first post-cRT follow-up (P = 0.096 for difference). Median survival for patients with ePD, PsPD and neither were 10.4, 27.4 and 13.0 months, respectively (P = 0.003 for ePD vs. PsPD, P = 0.19 for neither vs. PsPD groups). These data confirm a significant incidence of PsPD in post-cRT GBM patients, associated with improved median survival compared with those with neither ePD nor PsPD (not statistically significant). It appears likely that PsPD actually represents tumour response, conflicting with the traditional notion that increase in lesion size on contrast-enhanced imaging represents disease progression. Early post-cRT imaging should thus be interpreted with caution. Accompanying clinical symptoms are more commonly associated with ePD, but do not reliably distinguish PsPD from ePD.

Full Text Available In this research work the original 45S5 bioactive glass (BG was modified by introducing zinc and/or strontium oxide (6% mol in place of calcium oxide. Sr was added for its ability to stimulate bone formation, Zn for its role in bone metabolism, antibacterial properties and anti-inflammatory effect. The glasses were produced by means of melting and quenching process. SEM and XRD analyses evidenced that Zr and Sr introduction did not modify the glass structure and morphology, while compositional analysis (EDS demonstrated the effective addition of these elements inside the glass network. Bioactivity test in simulated body fluid (SBF up to one month evidenced a reduced bioactivity kinetics for Zn-doped glasses. Doped glasses were combined with chitosan to produce organic/inorganic composite coatings on stainless steel AISI 316L by electrophoretic deposition (EPD. Two EPD processes were considered for coating development, namely direct current EPD (DC-EPD and alternating current EPD (AC-EPD. The stability of the suspension was analysed and the deposition parameters were optimized. Tape and bending tests demonstrated a good coating-substrate adhesion for coatings containing 45S5-Sr and 45S5-ZnSr glasses, while the adhesion to the substrate decreased by using 45S5-Zn glass. FTIR analyses demonstrated the composite nature of coatings and SEM observations indicated that glass particles were well integrated in the polymeric matrix, the coatings were fairly homogeneous and free of cracks; moreover the AC-EPD technique provided better results than DC-EPD in terms of coating quality. SEM, XRD analyses and Raman spectroscopy, performed after bioactivity test in SBF solution, confirmed the bioactive behaviour of 45S5-Sr containing coating, while coatings containing Zn exhibited no hydroxyapatite formation.

El estudio reveló que, respecto a 1973, la prevalencia de caries disminuyó el 55,0%, en tanto que la proporción de niños con dientes sanos fue mayor en el 26,7%. La frecuencia y severidad de la caries aumentó a medida que descendía la ubicación social del niño. En el nivel económicosocial más alto (NES I = burguesías empresarial y gerencial, los índices de caries fueron significativamente menores que en el nivel económicosocial más bajo (NES III = proletariado típico, proletariado no típico y subproletariado: ceo-d de 0,8 y 2,7 y ceo-s de 0,9 y 4,9, respectivamente. En el NES III, los principales componentes del ceo-d fueron dientes cariados y con extracción indicada, mientras que en el NES I fueron los dientes obturados. La proporción de niños sin experiencia de caries fue del 63,1% en el NES I y del 11,5% en el NES III. Inversamente, el índice de salud bucal resultó más alto en el NES I (8,8 que en el NES III (5,1. El gasto demandado por niño para el tratamiento restaurativo es aproximadamente dos veces y media más alto en el NES III que en el NES I. Considerando toda la muestra, el gasto en el NES III resultaría más de diez veces superior al del NES I. Se concluye que la programación de la atención odontológica privilegiando a los niños del NES III, que son los de mayor riesgo de enfermar, puede contribuir a contrarrestar los desniveles en el estado de salud bucal.Descrevem-se os resultados de uma pesquisa feita sobre uma amostra de 1.115 pré-escolares (5 anos de jardins de infância da cidade de Córdoba (Argentina com o objetivo de estabelecer a prevalência e distribuição da cárie dental segundo o nível socioeconómico.

Objective: To investigate the Value of embolic protection device (EPD)in renal artery stenting (RAS)for the patients with normal renal function. Methods: Total 24 patients (26 renal arteries) suffering from renal artery stenosis with normal serum creatinine were divided into two groups: EPD group (n12)and non-EPD group (n=12). Serum creatinine was calculated and analized statistically between the two groups, 1 month and 6months after stenting respectively, and followed by comparisons taking inside of each group and between both groups. Results: Serum creatinine of the EPD and non-EPD groups before, 1 month and 6 month after stenting were(99.18 ± 18.26) μmol/L, (101.73 ± 12.65) μmol/L, (96.82 ± 15.81) μmol/L and (100.18 ± 19.81) μmol/L, (107.36 ± 29.49) μmol/L, (127.64 ± 88.05) μmol/L, respectively; showing no significant difference inside each group individually (P>0.05), and also no statistically significant difference between the two groups (P>0.05). Conclusion: For the patients suffering from renal artery stenosis with normal serum creatinine, application of EPD may have no impact on renal function. Further evaluation is needed. (authors)

The Empirical Phase Diagram (EPD) technique is a vector-based multidimensional analysis method for summarizing large data sets from a variety of biophysical techniques. It can be used to provide comprehensive preformulation characterization of a macromolecule’s higher-order structural integrity and conformational stability. In its most common mode, it represents a type of stimulus-response diagram using environmental variables such as temperature, pH, and ionic strength as the stimulus, with alterations in macromolecular structure being the response. Until now EPD analysis has not been available in a high throughput mode because of the large number of experimental techniques and environmental stressor/stabilizer variables typically employed. A new instrument has been developed that combines circular dichroism, UV-absorbance, fluorescence spectroscopy and light scattering in a single unit with a 6-position temperature controlled cuvette turret. Using this multifunctional instrument and a new software system we have generated EPDs for four model proteins. Results confirm the reproducibility of the apparent phase boundaries and protein behavior within the boundaries. This new approach permits two EPDs to be generated per day using only 0.5 mg of protein per EPD. Thus, the new methodology generates reproducible EPDs in high-throughput mode, and represents the next step in making such determinations more routine. PMID:22447621

A comparison of a new multinomial stopping rule with stopping rules of fleming and gehan in single arm phase II cancer clinical trials

Full Text Available Abstract Background Response rate (RR alone may be insensitive to drug activity in phase II trials. Early progressive disease (EPD could improve sensitivity as well as increase stage I stopping rates. This study compares the previously developed dual endpoint stopping rule (DESR, which incorporates both RR and EPD into a two-stage, phase II trial, with rules using only RR. Methods Stopping rules according to the DESR were compared with studies conducted under the Fleming (16 trials or Gehan (23 trials designs. The RR hypothesis for the DESR was consistent with the comparison studies (ralt = 0.2, rnul = 0.05. Two parameter sets were used for EPD rates of interest and disinterest respectively (epdalt, epdnul: (0.4, 0.6 and (0.3, 0.5. Results Compared with Fleming, the DESR was more likely to allow stage two of accrual and to reject the null hypothesis (Hnul after stage two, with rejection being more common with EPD parameters (0.4, 0.6 than (0.3, 0.5. Compared with Gehan, both DESR parameter sets accepted Hnul in 15 trials after stage I compared with 8 trials by Gehan, with consistent conclusions in all 23 trials after stage II. Conclusions The DESR may reject Hnul when EPD rates alone are low, and thereby may improve phase II trial sensitivity to active, cytostatic drugs having limited response rates. Conversely, the DESR may invoke early stopping when response rates are low and EPD rates are high, thus shortening trials when drug activity is unlikely. EPD parameters should be chosen specific to each trial.

Evaluation of the Edinburgh Post Natal Depression Scale using Rasch analysis

2006-06-01

Full Text Available Abstract Background The Edinburgh Postnatal Depression Scale (EPDS is a 10 item self-rating post-natal depression scale which has seen widespread use in epidemiological and clinical studies. Concern has been raised over the validity of the EPDS as a single summed scale, with suggestions that it measures two separate aspects, one of depressive feelings, the other of anxiety. Methods As part of a larger cross-sectional study conducted in Melbourne, Australia, a community sample (324 women, ranging in age from 18 to 44 years: mean = 32 yrs, SD = 4.6, was obtained by inviting primiparous women to participate voluntarily in this study. Data from the EPDS were fitted to the Rasch measurement model and tested for appropriate category ordering, for item bias through Differential Item Functioning (DIF analysis, and for unidimensionality through tests of the assumption of local independence. Results Rasch analysis of the data from the ten item scale initially demonstrated a lack of fit to the model with a significant Item-Trait Interaction total chi-square (chi Square = 82.8, df = 40; p Conclusion The results of this study suggest that EPDS, in its original 10 item form, is not a viable scale for the unidimensional measurement of depression. Rasch analysis suggests that a revised eight item version (EPDS-8 would provide a more psychometrically robust scale. The revised cut points of 7/8 and 9/10 for the EPDS-8 show high levels of agreement with the original case identification for the EPDS-10.

The objective of this study was to evaluate the contraceptive efficacy and clinical performance of a Nestorone subdermal implant (NES) in the postpartum period. NES (n = 100) and Copper T intrauterine device (T-Cu; n = 100) acceptors initiated contraception at 8 weeks postpartum and were followed at monthly intervals during the first year and at 3-month intervals thereafter. Pregnancy rates, breastfeeding performance, infant growth, bleeding pattern, and side effects were assessed. Blood and milk NES concentration were measured. No pregnancy occurred in 2195 and 2145 woman-months of NES implant and T-Cu use, respectively. No effect of NES on lactation and infant growth and no serious adverse events were observed. Lactational amenorrhea was significantly longer in NES users (353 +/- 20 days) than in T-Cu users (201 +/- 11 days). More NES users (55.8%) experienced prolonged bleedings than did T-Cu users (36.2%). Concentrations of NES in breast milk ranged between 54-135 pmol/liter. The Nestorone implant is a highly effective contraceptive, safe for breastfed infants because the steroid is inactive by the oral route.

The relationships between postpartum depression and demographic characteristics, social support, marital relationship, negative and passive acceptance of the mother role, and parenting behavior were examined in 215 mothers who live in Tokyo, Japan, and who have a child less than 1 year old. Social support from husbands or friends and marital relationship were found to be significantly related to the Edinburgh Postnatal Depression Scale (EPDS) score. Although negative and passive acceptance of the mother role was also related to the EPDS score and neglectful parenting behavior, it was not found to be related to aggressive parenting behavior. The correlation between EPDS score and neglectful or aggressive parenting behavior was also significant, with aggressive parenting behavior more strongly related to the EPDS score.

Assessment of the Effectiveness of Ectomycorrhizal Inocula to Promote Growth and Root Ectomycorrhizal Colonization in Pinus patula Seedlings Using the Most Probable Number Technique

Directory of Open Access Journals (Sweden)

Manuel Restrepo-Llano

2014-01-01

Full Text Available The aim of this study was to evaluate the response of Pinus patula seedlings to two inocula types: soil from a Pinus plantation (ES and an in vitro produced inoculum (EM. The most probable number method (MPN was used to quantify ectomycorrhizal propagule density (EPD in both inocula in a 7-order dilution series ranging from 100 (undiluted inoculum to 10−6 (the most diluted inoculum. The MPN method allowed establishing differences in the number of infective ectomycorrhizal propagules’ density (EPD (ES=34 per g; EM=156 per g. The results suggest that the EPD of an inoculum may be a key factor that influences the successfulness of the inoculation. The low EPD of the ES inoculum suggests that soil extracted from forest plantations had very low effectiveness for promoting root colonization and plant growth. In contrast, the high EPD found in the formulated inoculum (EM reinforced the idea that it is better to use proven high quality inocula for forest nurseries than using soil from a forestry plantation.

[What the patient's history tells us about their nonepileptic seizures].

2014-10-01

The aetiology of "psychogenic" non-epileptic seizures (NES) remains poorly understood and the differentiation of NES from epilepsy can be a difficult. In the first part of this review article we focus on recent insights into the neurobiological underpinnings of NES. We summarise a number of studies demonstrating the importance of abnormalities of emotion regulation in patients with NES. Evidence for abnormal emotion regulation comes from both self-report and experimental studies of pre-conscious cognitive processes. These studies show that NES are not the only manifestation of abnormal mental processing in these patients and that excessive social threat avoidance and emotional dysregulation are also evident between seizures and may therefore contribute to disability beyond the seizures themselves. In the second part of this review, we describe the findings of a number of studies, which have examined differences between the communication behaviour of patients with NES and those with epilepsy. We argue, that, whilst these studies initially aimed to help clinicians with the differential diagnosis of NES and epilepsy, close sociolinguistic analysis of patient's talk can also provide clues about the aetiology of NES. We conclude that the interaction of patient with NES with the doctor can be interpreted as a manifestation of avoidance and a demonstration of helplessness perhaps intended to secure active support from the doctor. In the third part of this review, we suggest that a close reading of a transcript of the interaction between a patient with NES and her doctor (and perhaps attentive listening to how patients' talk about themselves and their disorder) can yield clues to the causes of NES in individual cases.

BACKGROUND: Screening for postnatal depression using the Edinburgh Postnatal Depression Scale (EPDS) has been widely recommended and implemented in primary care, although little is known about how acceptable it is to women. AIM: To explore the acceptability to women of postnatal screening by health visitors with the EPDS. DESIGN OF STUDY: Qualitative interview study. SETTING: Postnatal patients from 22 general practices within the area of Oxford City Primary Care Group. METHOD: Thirty-nine postnatal women from a purposive sample were interviewed, chosen on the basis of different general practices, EPDS results at eight weeks and eight months postnatal, and whether 'listening visits' were received. The interviews were analysed using the constant comparative method. RESULTS: Just over half of the women interviewed found screening with the EPDS less than acceptable, whatever their postnatal emotional health. The main themes identified were problems with the process of screening and, in particular, the venue, the personal intrusion of screening and stigma. The women interviewed had a clear preference for talking about how they felt, rather than filling out a questionnaire. CONCLUSION: For this sample, routine screening with the EPDS was less than acceptable for the majority of women. This is of concern, as universal screening with the EPDS for the detection of postnatal depression is already recommended and widespread in primary care. PMID:14601337

This study aimed to assess the psychometric properties and diagnostic accuracy of the EPDS in a sample of Iranian women.Methods: Using stratified sampling 262 postpartum women (2 weeks-3 months after delivery were selected from urban and rural health center in the city of Isfahan. They were interviewed using EPDS and Hamilton depression rating scale (HDRS. Data were assessed using factor analysis, diagnosis analysis of receiver operating characteristic (ROC curve, Cronbach's alpha and Pearson correlation coefficient.Results: The age of then participants ranged 18-45 years (26.6±5.1. Based on a cut-off point of >13 for HDRS, 18.3% of the participants. The overall reliability (Cronbach's alpha of EPDS was 0.79. There was a significant correlation (r2=0.60, P value<0.01 between EPDS and HDRS. Two factor analysis showed that anhedonia and depression were two explanatory factors. At a cut-off point12 the sensitivity of the questionnaire was 78% (95% CI: 73%-83% and its specificity was 75% (95% CI: 72%-78%. Conclusion: The Persian version of the EPDS showed appropriate psychometric properties diagnostic accuracy index. It can be used by health system professionals for detection, assessment and treatment for mothers with post partum depression.

Objective We sought to evaluate the psychometric properties of two widely used screening scales: the Patient Health Questionnaire (PHQ-9) and Edinburgh Postnatal Depression Scale (EPDS) among pregnant Peruvian women. Methods This cross-sectional study included 1,517 women receiving prenatal care from February 2012 to March 2013. A structured interview was used to collect data using PHQ-9 and EPDS. We examined reliability, construct and concurrent validity between two scales using internal consistency indices, factor structures, correlations, and Cohen’s kappa. Results Both scales had good internal consistency (Cronbach’s alpha > 0.8). Correlation between PHQ-9 and EPDS scores was fair (rho=0.52). Based on exploratory factor analysis (EFA), both scales yielded a two-factor structure. EFA including all items from PHQ-9 and EPDS yielded four factors, namely, “somatization”, “depression and suicidal ideation”, “anxiety and depression”, and “anhedonia”. The agreement between the two scales was generally fair at different cutoff scores with the highest Cohen’s kappa being 0.46. Conclusions Both the PHQ-9 and EPDS are reliable and valid scales for antepartum depression assessment. The PHQ-9 captures somatic symptoms, while EPDS detects depressive symptoms comorbid with anxiety during early pregnancy. Our findings suggest simultaneous administration of both scales may improve identification of antepartum depressive disorders in clinical settings. PMID:24766996

Establishing a coherent and replicable measurement model of the Edinburgh Postnatal Depression Scale.

The 10-item Edinburgh Postnatal Depression Scale (EPDS) is an established screening tool for postnatal depression. Inconsistent findings in factor structure and replication difficulties have limited the scope of development of the measure as a multi-dimensional tool. The current investigation sought to robustly determine the underlying factor structure of the EPDS and the replicability and stability of the most plausible model identified. A between-subjects design was used. EPDS data were collected postpartum from two independent cohorts using identical data capture methods. Datasets were examined with confirmatory factor analysis, model invariance testing and systematic evaluation of relational and internal aspects of the measure. Participants were two samples of postpartum women in England assessed at three months (n = 245) and six months (n = 217). The findings showed a three-factor seven-item model of the EPDS offered an excellent fit to the data, and was observed to be replicable in both datasets and invariant as a function of time point of assessment. Some EPDS sub-scale scores were significantly higher at six months. The EPDS is multi-dimensional and a robust measurement model comprises three factors that are replicable. The potential utility of the sub-scale components identified requires further research to identify a role in contemporary screening practice. Copyright © 2018 The Authors. Published by Elsevier B.V.

Streamlining environmental product declarations: a stage model

Lefebvre, Elisabeth; Lefebvre, Louis A.; Talbot, Stephane; Le Hen, Gael

2001-02-01

General public environmental awareness and education is increasing, therefore stimulating the demand for reliable, objective and comparable information about products' environmental performances. The recently published standard series ISO 14040 and ISO 14025 are normalizing the preparation of Environmental Product Declarations (EPDs) containing comprehensive information relevant to a product's environmental impact during its life cycle. So far, only a few environmentally leading manufacturing organizations have experimented the preparation of EPDs (mostly from Europe), demonstrating its great potential as a marketing weapon. However the preparation of EPDs is a complex process, requiring collection and analysis of massive amounts of information coming from disparate sources (suppliers, sub-contractors, etc.). In a foreseeable future, the streamlining of the EPD preparation process will require product manufacturers to adapt their information systems (ERP, MES, SCADA) in order to make them capable of gathering, and transmitting the appropriate environmental information. It also requires strong functional integration all along the product supply chain in order to ensure that all the information is made available in a standardized and timely manner. The goal of the present paper is two fold: first to propose a transitional model towards green supply chain management and EPD preparation; second to identify key technologies and methodologies allowing to streamline the EPD process and subsequently the transition toward sustainable product development

Nonepileptic seizures (NES) apparently look like epileptic seizures, but are not associated with ictal electrical discharges in the brain. NES constitute one of the most important differential diagnoses of epilepsy. They have been recognized as a distinctive clinical phenomenon for centuries, and video/electroencephalogram monitoring has allowed clinicians to make near-certain diagnoses. NES are supposedly unrelated to organic brain lesions, and despite the preponderance of a psychiatric/psychological context, they may have an iatrogenic origin. We report a patient with NES precipitated by levetiracetam therapy; in this case, NES was observed during the disappearance of epileptiform discharges from the routine video/electroencephalogram. We discuss the possible mechanisms underlying NES with regard to alternative psychoses associated with the phenomenon of the forced normalization process.

This study aimed to probe the potential of nanoemulsions (NEs consisting of hemp oil and less surfactants in ameliorating the oral bioavailability of BCL. BCL-loaded NEs (BCL-NEs were prepared by high-pressure homogenization technique to reduce the amount of surfactants. BCL-NEs were characterized by particle size, entrapment efficiency (EE, in vitro drug release, and morphology. Bioavailability was studied in Sprague-Dawley rats following oral administration of BCL suspensions, BCL conventional emulsions, and BCL-NEs. The obtained NEs were ~90 nm in particle size with an EE of 99.31%. BCL-NEs significantly enhanced the oral bioavailability of BCL, up to 524.7% and 242.1% relative to the suspensions and conventional emulsions, respectively. BCL-NEs exhibited excellent intestinal permeability and transcellular transport ability. The cytotoxicity of BCL-NEs was documented to be low and acceptable for oral purpose. Our findings suggest that such novel NEs and preparative process provide a promising alternative to current formulation technologies and suitable for oral delivery of drugs with bioavailability issues.

2007-01-01

Neurological and cognitive aspects of adolescent psychotic disorders are understudied. The authors assessed 19 adolescents with psychosis and 16 healthy comparison subjects using the Neurological Evaluation Scale (NES) and age-appropriate Wechsler intelligence quotient (IQ) scales. NES scores were highest and IQ scores were lowest among subjects with psychosis. Subjects with psychosis did not demonstrate age-related decreases in NES score. The combination of NES and IQ scores predicted both the presence of psychosis and psychiatric diagnosis. There were no relationships between medication status and either NES or IQ scores. These results support a broadly conceived neurodevelopmental formulation of adolescent psychotic disorders.

Several controlled clinical trials have shown that specific immunotherapy (SIT) using incremental injections of allergens can be effective in the treatment of allergic rhinitis and asthma. Nevertheless, the risk of side effects have led to some recommended limitations of SIT. Enzyme-potentiated desensitization (EPD) is a proposed method for immunotherapy with very low doses of mixed allergens plus beta-glucuronidase enzyme, for which irrelevant or no side effects have been claimed. The aim of this study was to determine the clinical efficacy of EPD in the treatment of pollinosis. A double-blind placebo-controlled trial of EPD among 20 patients sensitive to Parietaria and grass pollen was performed. All patients recorded daily symptom scores for nine months following a single intradermal injection of EPD or buffered saline received in February. Symptoms recorded were nasal itching and obstruction, sneezing, rhinorrhea, itchy eyes and excessive tear production. Moreover, total and specific lgE were measured and CD3+, CD4+ and CD8+ peripheral blood lymphocytes were counted at different times. In the same period, ten additional subjects, with an allergic clinical profile similar to the subjects admitted to the double-blind trial, were studied in an open clinical trial in order to evaluate the effects of EPD without enzyme using a mixture of allergens. Symptom scores were higher in the placebo group (p < 0.001), with a similar level of significance for both global symptom score and for each individual symptom. Active-treated patients had a significant post-treatment increase in the mean percentage of T-CD8+ peripheral blood cells and a significant post-seasonal decrease in the mean percentage of Parietaria specific lgE. On the contrary, placebo-treated patients had a borderline significant post-seasonal decrease in the mean percentage of CD8+ circulating cells and a significant seasonal increase in the mean percentage of Parietaria specific lgE with no significant post

Personal radiation monitoring is a basic procedure to verify the compliance to regulatory requirements for radiological protection. Electronic personal dosimeters (EPD) based on solid state detectors have largely been used for personnel monitoring; including for pulsed radiation beams where their responses are not well known and deficiencies have been reported. In this work, irradiation conditions for testing the response of EPDs in both continuous and pulsed X-ray beams were studied to be established in a constant potential Seifert-Pantak and in a medical Pulsar 800 Plus VMI X-ray machines. Characterization of X-ray beams was done in terms of tube voltage, half-value layer, mean energy and air kerma rate. A Xi R/F Unfors solid state dosimeter used as reference for air kerma measurements was verified against a RC-6 and 10X6-6 Radical ionization chambers as far its metrological coherence. Rad-60 RADOS, PDM- 11 Aloka and EPD MK2 Thermo electron EPDs were selected to be tested in terms of relative intrinsic error and energy response in similar to IEC RQR, IEC RQA and ISO N reference radiations. Results demonstrated the reliability of the solid state Xi R/F Unfors dosimeter to be as reference dosimeter although its response was affected by heavily filtered beams. Results also showed that relative intrinsic errors in the response of the EPDs in terms of personal dose equivalent, Hp(10), were higher than the requirement established for continuous beams. In pulsed beams, some EPDs showed inadequate response and high relative intrinsic errors. This work stressed the need of performing additional checks for EPDs, besides the limited 137 Cs beam calibration, before using them in pulsed X-ray beams. (author)

Mental health problems among women of reproductive age group contribute to 7% of Global Burden of Diseases of women of all ages. Purpose of this study was to determine the prevalence and correlates of antenatal depression among pregnant women in Anuradhapura, Sri Lanka, and to explore the factor structure of EPDS. Pregnant women with gestational age of 24-36 weeks and residing in Anuradhapura district, Sri Lanka were recruited to the study using a two stage cluster sampling procedure. Sinhalese version of Edinburgh Post Partum Depression Scale (EPDS) and an interviewer administered questionnaire was use to collect data. A cut off value of 9 was used for the Sinhalese version of EPDS. A total of 376 pregnant women were studied. Median EPDS score among pregnant women was 5 (IQR 2-8). Prevalence of antenatal depression in this study sample was 16.2% (n = 61). Thought of self harming (item number 10) was reported by 26 pregnant women (6.9%). None of the socio-demographic factors were associated with depression in this study sample. Having heart burn was significantly associated with depressive symptoms (p = 0.041). Sri Lankan version of EPDS showed a two factor solution. Anxiety was not emerged as a separate factor in this analysis. Prevalence of antenatal depression in Anuradhapura, Sri Lanka was relatively low. Anxiety was not emerged as a separate factor in the Sinhalese version of the EPDS.

To examine the safety and efficacy of the SpiderFX embolic protection device (EPD) in the below-the-knee (BTK) circulation in patients with critical limb ischemia (CLI). A single-center retrospective review was performed to identify patients with CLI and single-vessel runoff in whom the SpiderFX EPD was used in the BTK circulation. Technical success and device-related complications were the primary endpoints. Retrieval of macroscopic debris in the EPD, 1-year freedom from major adverse limb events (MALEs), and 30-day perioperative death were also evaluated. A major amputation, surgical bypass, endovascular thrombectomy, or endovascular thrombolysis was considered a MALE. Thirty-six patients (21 men; mean age, 75.8 y) treated between 2008 and 2013 had endovascular revascularization with use of the SpiderFX EPD in the BTK circulation. The SpiderFX EPD was successfully deployed in all cases; the technical success rate of revascularization was 100%. Two minor and zero major complications were observed related to the SpiderFX. Two MALEs, a major amputation and a subsequent surgical bypass, were observed in the cohort. All MALEs occurred within 1 year of treatment (1-y freedom from MALE rate, 90%). Debris was retrieved in the SpiderFX device in 47% of patients. The use of the SpiderFX EPD in the BTK circulation in patients with CLI is safe and frequently retrieves debris. Copyright © 2014 SIR.

Su, Y; Zhitomirsky, I

2013-02-14

The electrophoretic deposition (EPD) method has been developed for the fabrication of MnO(2)-multiwalled carbon nanotube (MWCNT) films for application in electrochemical supercapacitors (ESs). For MWCNT applications, which depend on electrical conductivity, it is challenging to achieve dispersion and EPD of pristine MWCNT and avoid defects due to chemical treatment or functionalization. An important finding was the possibility of efficient dispersion and controlled EPD of MWCNT using calconcarboxylic acid (CCA). Moreover, the use of CCA allowed efficient dispersion of MnO(2) in concentrated suspensions and EPD of MnO(2) films. The comparison of the experimental data for chromotrope FB (CFB) and CCA and chemical structures of the molecules provided insight into the mechanism of CCA adsorption on MnO(2). The fabrication of stable suspensions of MnO(2) nanoparticles containing MWCNT, and controlled codeposition of both materials is a crucial aspect in the EPD of composites. The new approach was based on the use of CCA as a charging and dispersing agent for EPD of MnO(2) nanoparticles and MWCNT. The deposition yield measurements at various experimental conditions and Fourier transform infrared spectroscopy data, coupled with results of electron microscopy, thermogravimetric, and differential thermal analysis provided evidence of the formation of MnO(2)-MWCNT composites. The electrochemical testing results and impedance spectroscopy data showed good capacitive behavior of the composite films and the beneficial effect of MWCNTs.

:Depression may occur in teenager pregnant women. The use of a validated tool for screening depression is highly recommended. The Edinburgh postnatal depression scale (EPDS) is a screening tool for depression used in women during the postnatal period and pregnancy. However, the EPDS has not been validated in teenager pregnant women. Therefore, we sought to validate a Spanish translated Mexican version of the EPDS in a population of teenager pregnant women. One hundred and twenty teenager pregnant women attending routine prenatal consultations in a public hospital in Durango City, Mexico participated in the study. All participants submitted a revised Spanish translated Mexican version of the EPDS and were examined by a psychiatrist to evaluate the presence of depression by using DSM-IV criteria. Of the 120 teenager pregnant women studied, 2 had major depression and 25 had minor depression according to the DSM-IV criteria. The optimal EPDS cut-off for screening combined major and minor depression in teenager pregnant women was 8/9. At this threshold, we found a sensitivity of 70.4%, a specificity of 84.9%, a positive predictive value of 47.6%, a negative predictive value of 91.0%, and an area under the curve of 0.81 (95% confidence interval: 0.56-1.07). The EPDS can be used for screening depression in Mexican teenager pregnant women whenever a cut-off score of 8/9 is used.

New generation of ''legal'' dosemeters

International Nuclear Information System (INIS)

Fletcher, R.

1991-01-01

In the early 1980s research at the National Radiological Protection Board in the UK proved the feasibility of using solid state electronics in an entirely new dosimetry technology - capable of reaching right down into the low energy photon ranges, and able to detect beta radiation. In 1988 the NRPB undertook a joint venture with Siemens Plessey Controls to develop a marketable personal dosemeter meeting full Health and Safety Executive approval as a ''legal'' instrument. The Electronic Personal Dosemeter (EPD) was thus conceived, and will reach the pre-production stage early this year. The EPD makes use of state-of-the-art silicon integrated circuit technology, with a custom amplifier and microprocessor system. The liquid crystal display continuously shows the accumulated short-term penetrating dose in terms of the Hp (10) unit, and can also show superficial dose and dose rates. Because the EPD must be continuously powered, the custom lithium battery was commissioned to ensure a minimum service interval of 12 months. The EPD is the size and weight of a small pocket pager. Although dose data can be read directly from the EPD, a comprehensive data management system is needed to effect real-life use in industry. The EPD thus communicates by infra-red link to a reader unit which interfaces an IBM-compatible PC, allowing authorized personnel to read the dose memories and perform dose alarm threshold settings.

1988-01-01

The results of the Independent Orbiter Assessment (IOA) of the Failure Modes and Effects Analysis (FMEA) and Critical Items List (CIL) are presented. The IOA effort first completed an analysis of the Orbital Maneuvering System (OMS) hardware and Electrical Power Distribution and Control (EPD and C), generating draft failure modes and potential critical items. To preserve independence, this analysis was accomplished without reliance upon the results contained within the NASA FMEA/CIL documentation. The IOA results were then compared to the proposed Post 51-L NASA FMEA/CIL baseline. This report documents the results of that comparison for the Orbiter OMS hardware. The IOA analysis defined the OMS as being comprised of the following subsystems: helium pressurization, propellant storage and distribution, Orbital Maneuvering Engine, and EPD and C. The IOA product for the OMS analysis consisted of 284 hardware and 667 EPD and C failure mode worksheets that resulted in 160 hardware and 216 EPD and C potential critical items (PCIs) being identified. A comparison was made of the IOA product to the NASA FMEA/CIL baseline which consisted of 101 hardware and 142 EPD and C CIL items.

Integrated topology for an aircraft electric power distribution system using MATLAB and ILP optimization technique and its implementation

Science.gov (United States)

Madhikar, Pratik Ravindra

The most important and crucial design feature while designing an Aircraft Electric Power Distribution System (EPDS) is reliability. In EPDS, the distribution of power is from top level generators to bottom level loads through various sensors, actuators and rectifiers with the help of AC & DC buses and control switches. As the demands of the consumer is never ending and the safety is utmost important, there is an increase in loads and as a result increase in power management. Therefore, the design of an EPDS should be optimized to have maximum efficiency. This thesis discusses an integrated tool that is based on a Need Based Design method and Fault Tree Analysis (FTA) to achieve the optimum design of an EPDS to provide maximum reliability in terms of continuous connectivity, power management and minimum cost. If an EPDS is formulated as an optimization problem then it can be solved with the help of connectivity, cost and power constraints by using a linear solver to get the desired output of maximum reliability at minimum cost. Furthermore, the thesis also discusses the viability and implementation of the resulted topology on typical large aircraft specifications.

This study examined the association between a single nucleotide polymorphism in the hydroxysteroid (11-beta) dehydrogenase 1 gene and neuroticism, as well as the possible mediatory role of neuroticism in the association between the polymorphism and postpartum depressive symptoms. 769 women received questionnaires containing the Edinburgh Postnatal Depression Scale (EPDS) at six weeks postpartum and demographic data at pregnancy week 17 and 32 and at six weeks postpartum, as well as the Swedish universities Scales of Personality at pregnancy week 32. Linear regression models showed an association between the GG genotype and depressive symptoms. When neuroticism was introduced in the model, it was associated with EPDS score, whereas the association between the GG genotype and EPDS became borderline significant. A path analysis showed that neuroticism had a mediatory role in the association between the polymorphism and EPDS score. The use of the EPDS, which is a self-reporting instrument. Neuroticism was associated with the polymorphism and had a mediatory role in the association between the polymorphism and postpartum depression. This finding elucidates the genetic background of neuroticism and postpartum depression. Copyright © 2016 Elsevier B.V. All rights reserved.

2003-04-01

To determine the rate of depression in a group of postpartum Nigerian women and to validate the Edinburgh Postnatal Depression Scale (EPDS) in this group. Between April and August 2000, all postpartum women who remained in the maternity ward for up to 7 days, and those who attended the postnatal clinics of Nnamdi Azikiwe University Teaching Hospital were recruited. Translated local language versions of the EPDS and the Zung Self-Rating Depression Scale were used to screen the subjects. A structured interview schedule was adapted from the depression section of the Composite International Diagnostic Interview and affective module of the ICD-10 Symptom Check List to assess screened subjects. The total rejection rate was 23%, with 225 women participating in the study. Twenty-four subjects (10.7%) had depression. At the optimal cut-off score of 9, the EPDS had a sensitivity of 0.75, and specificity of 0.97. The EPDS clearly distinguished between depressed and non-depressed postpartum mothers (t = 7.63, P < 0.001, df = 222). Because of its brevity and acceptability, it is recommended that the EPDS be used in routine postnatal screening.

Altered Dynamic Postural Control during Step Turning in Persons with Early-Stage Parkinson’s Disease

Directory of Open Access Journals (Sweden)

Jooeun Song

2012-01-01

Full Text Available Persons with early-stage Parkinson’s disease (EPD do not typically experience marked functional deficits but may have difficulty with turning tasks. Studies evaluating turning have focused on individuals in advanced stages of the disease. The purpose of this study was to compare postural control strategies adopted during turning in persons with EPD to those used by healthy control (HC subjects. Fifteen persons with EPD, diagnosed within 3 years, and 10 HC participated. Participants walked 4 meters and then turned 90°. Dynamic postural control was quantified as the distance between the center of pressure (COP and the extrapolated center of mass (eCOM. Individuals with EPD demonstrated significantly shorter COP-eCOM distances compared to HC. These findings suggest that dynamic postural control during turning is altered even in the early stages of PD.

Curcumin nanoemulsions (Cur-NEs) were developed with various surfactant concentrations by using high pressure homogenization and finally applied to the commercial milk system. Characterization of Cur-NEs was performed by measuring the droplet size and polydispersity index value at different Tween 20 concentrations. The morphology of the Cur-NEs was observed by confocal laser scanning microscopy and transmission electron microscopy. Antioxidant activity and in vitro digestion ability were tested using 2,2-diphenyl-1-picrylhydrazyl, 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt, pH-stat method, and thiobarbituric acid reactive substances assays. Cur-NEs were found to be physically stable for 1 mo at room temperature. The surfactant concentration affects particle formation and droplet size. The mean droplet size decreased from 122 to 90 nm when surfactant concentration increased 3 times. Cur-NEs had shown an effective oxygen scavenging activity. Cur-NEs-fortified milk showed significantly lower lipid oxidation than control (unfortified) milk and milk containing curcumin-free nanoemulsions. These properties make Cur-NEs suitable systems for the beverage industry. © 2016 Institute of Food Technologists®

Night eating among veterans with obesity.

Science.gov (United States)

Dorflinger, Lindsey M; Ruser, Christopher B; Masheb, Robin M

2017-10-01

The obesity rate is higher among veterans than the general population, yet few studies have examined their eating behaviors, and none have examined the presence of night eating and related comorbidities. This study examines night eating syndrome (NES) among veterans seeking weight management treatment, and relationships between NES and weight, insomnia, disordered eating, and psychological variables. The sample consisted of 110 veterans referred to a weight management program at VA Connecticut Healthcare System. More than one out of ten veterans screened positive for NES, and one-third screened positive for insomnia. Most individuals screening positive for NES also screened positive for insomnia. Night eating was associated with higher BMI, and with higher scores on measures of binge eating, emotional overeating, and eating disorder symptomatology. Veterans screening positive for NES were also significantly more likely to screen positive for depression and PTSD. When controlling for insomnia, only the relationships between night eating and binge and emotional eating remained significant. Those screening positive for PTSD were more likely to endorse needing to eat to return to sleep. Findings suggest that both NES and insomnia are common among veterans seeking weight management services, and that NES is a marker for additional disordered eating behavior, specifically binge eating and overeating in response to emotions. Additional studies are needed to further delineate the relationships among NES, insomnia, and psychological variables, as well as to examine whether specifically addressing NES within behavioral weight management interventions can improve weight outcomes and problematic eating behaviors.

In this study we aimed to investigate the prevalance and clinical correlations of night eating syndrome (NES) in a sample of psychiatric outpatients. Four hundred thirthy three consecutive psychiatric out-patients older than 18years were evaluated in the outpatient clinics using clinical interview according to the DSM-IV with regard to psychiatric diagnosis. Participants were also screened for presence of NES utilizing both clinical interview and self report based on Night Eating Questionnaire (NEQ) instruments. Sociodemographic and clinical features such as age, gender, education level, socioeconomic level and body mass index (BMI) were also recorded. The Body Shape Questionnaire (BSQ) and the Symptom Checklist-90 Revised (SCL-90R) were administered. Based on the proposed diagnostic criteria of the NES via utilizing clinical interview method, 97 (32 male, 65 female) of the sample met diagnostic criteria for NES. The point prevalence of NES was 22.4%. No statistically significant differences were found between the two groups in terms of age, gender, marital status, education and BMI. The patients with NES had higher NEQ, BSQ and SCL-90R subscale scores than patients without NES. Prevalance of depressive disorder, impulse control disorder, and nicotine dependency was higher among patients with NES. No differences were found with regard to the medication (antipsychotics, antidepressants and mood stabilizers). Night eating syndrome is prevalent among psychiatric outpatients and associated with depression, impulse control disorder, and nicotine dependency. Body dissatisfaction and higher symptom severity are also other risk factors for the development of NES. Copyright © 2014 Elsevier Inc. All rights reserved.

Electrophoretic display (EPD) is a non-luminous type display using electrophoresis of particles dispersing in a solvent. This kind of display is particularly good at displaying like printing matters. By micro-encapsulating the dispersion medium, a realization of the thin and flexible display device become possible. Further, an EPD (MC-EPD) using a microencapsulated suspension is a forceful candidate for realizing digital paper in the future. In this paper, principle and characteristics of the EPD are explained and application to rewritable sheet (MC-EPS) is introduced. MC-EPS is a rewritable sheet-like display formed by coating a flexible base material such as a polymer film or paper with microcapsules and applying an electric field from external. As an electrostatic latent image formation technique in the electro photography field can be applied as a voltage impression method, the development of the special writing equipment is unnecessary.

Noise enhanced stability effect in a metastable system with two different kinds of time delays and cross-correlated noises

International Nuclear Information System (INIS)

Jia Zhenglin; Mei Dongcheng

2011-01-01

We numerically investigate the influences of the time delay τ simultaneously existing in both the deterministic and fluctuating forces, the time delay τ r existing only in the fluctuating force and the cross-correlation strength λ on the enhancement of the mean first-passage time (MFPT) as a function of the additive D and the multiplicative α noise intensities in a metastable system. The results indicate that both the multiplicative and additive noises can induce the noise-enhanced stability (NES) effect. An increase of λ can enhance or weaken the NES effect induced by the additive noise, depending on the value of τ. However, it weakens the NES effect induced by the multiplicative noise with a suppression of the effect of λ caused by increasing τ. The τ-induced critical behavior on both NES effects can be observed, i.e. an increase of τ can enhance or restrain the NES effects induced by the two kinds of noises. With an increase of λ and τ, MFPT versus D shows a transition from one peak to two peaks and finally one peak, implying the multiple NES effect caused by λ and τ. An increase of τ r can enhance the NES effect induced by the additive noise and weaken the NES effect induced by the multiplicative noise.

A new surface fractal dimension for displacement mode shape-based damage identification of plate-type structures

Science.gov (United States)

Shi, Binkai; Qiao, Pizhong

2018-03-01

Vibration-based nondestructive testing is an area of growing interest and worthy of exploring new and innovative approaches. The displacement mode shape is often chosen to identify damage due to its local detailed characteristic and less sensitivity to surrounding noise. Requirement for baseline mode shape in most vibration-based damage identification limits application of such a strategy. In this study, a new surface fractal dimension called edge perimeter dimension (EPD) is formulated, from which an EPD-based window dimension locus (EPD-WDL) algorithm for irregularity or damage identification of plate-type structures is established. An analytical notch-type damage model of simply-supported plates is proposed to evaluate notch effect on plate vibration performance; while a sub-domain of notch cases with less effect is selected to investigate robustness of the proposed damage identification algorithm. Then, fundamental aspects of EPD-WDL algorithm in term of notch localization, notch quantification, and noise immunity are assessed. A mathematical solution called isomorphism is implemented to remove false peaks caused by inflexions of mode shapes when applying the EPD-WDL algorithm to higher mode shapes. The effectiveness and practicability of the EPD-WDL algorithm are demonstrated by an experimental procedure on damage identification of an artificially-induced notched aluminum cantilever plate using a measurement system of piezoelectric lead-zirconate (PZT) actuator and scanning laser Doppler vibrometer (SLDV). As demonstrated in both the analytical and experimental evaluations, the new surface fractal dimension technique developed is capable of effectively identifying damage in plate-type structures.

Visual Attention to Pictorial Food Stimuli in Individuals With Night Eating Syndrome: An Eye-Tracking Study.

Science.gov (United States)

Baldofski, Sabrina; Lüthold, Patrick; Sperling, Ingmar; Hilbert, Anja

2018-03-01

Night eating syndrome (NES) is characterized by excessive evening and/or nocturnal eating episodes. Studies indicate an attentional bias towards food in other eating disorders. For NES, however, evidence of attentional food processing is lacking. Attention towards food and non-food stimuli was compared using eye-tracking in 19 participants with NES and 19 matched controls without eating disorders during a free exploration paradigm and a visual search task. In the free exploration paradigm, groups did not differ in initial fixation position or gaze duration. However, a significant orienting bias to food compared to non-food was found within the NES group, but not in controls. A significant attentional maintenance bias to non-food compared to food was found in both groups. Detection times did not differ between groups in the search task. Only in NES, attention to and faster detection of non-food stimuli were related to higher BMI and more evening eating episodes. The results might indicate an attentional approach-avoidance pattern towards food in NES. However, further studies should clarify the implications of attentional mechanisms for the etiology and maintenance of NES. Copyright © 2017. Published by Elsevier Ltd.

To acquire highly efficient and cost-effective fuel cells, numerous research works have been carried out to the development low cost and excellent performance of electrocatalysts. In this paper, a solution-based electrophoretic deposition (EPD) technique for fabrication of Pt-based catalyst layers is studied. Nanographitic flake coatings used as catalyst support for sputtered platinium (Pt) were fabricated via the electrophoretic deposition (EPD) of dispersed nanographitic flakes in isopropyl alcohol. Magnesium nitrate hexahydrate (MNH) was used as an additive binder in the EPD process. Subsequently, the platinium particles were deposited by a direct sputtering on the fabricated nanographitic flake coatings.

Electrophoretic deposition (EPD) is attracting increasing attention as an effective technique for the processing of biomaterials, specifically bioactive coatings and biomedical nanostructures. The well-known advantages of EPD for the production of a wide range of microstructures and nanostructures as well as unique and complex material combinations are being exploited, starting from well-dispersed suspensions of biomaterials in particulate form (microsized and nanoscale particles, nanotubes, nanoplatelets). EPD of biological entities such as enzymes, bacteria and cells is also being investigated. The review presents a comprehensive summary and discussion of relevant recent work on EPD describing the specific application of the technique in the processing of several biomaterials, focusing on (i) conventional bioactive (inorganic) coatings, e.g. hydroxyapatite or bioactive glass coatings on orthopaedic implants, and (ii) biomedical nanostructures, including biopolymer–ceramic nanocomposites, carbon nanotube coatings, tissue engineering scaffolds, deposition of proteins and other biological entities for sensors and advanced functional coatings. It is the intention to inform the reader on how EPD has become an important tool in advanced biomaterials processing, as a convenient alternative to conventional methods, and to present the potential of the technique to manipulate and control the deposition of a range of nanomaterials of interest in the biomedical and biotechnology fields.

This report presents the results of a laboratory assessment of the performance of a new type of personal dosimeter. The Electronic Personal Dosimeter, or EPD, was developed jointly by the National Radiological Protection Board and Siemens Plessey Controls Limited, both of the United Kingdom. Twenty pre-production units of the EPD and a reader were purchased by Ontario Hydro for the assessment. The tests were conducted jointly by Ontario Hydro's Health and Safety Division and AECL Research's Chalk River Laboratories (CRL), with funding from the Candu Owner's Group. A total of 26 tests were conducted, divided between Ontario Hydro and AECL. The test results were compared with the relevant requirements of three standards. In general, the performance of the EPD was found to be quite acceptable. It met most of the relevant requirements of the three standards and most of the design specifications. However, the following deficiencies were found: slow response time; sensitivity to high-frequency EMF; poor resistance to dropping; and an alarm that is not loud enough. In addition, the response of the EPD to low-energy beta rays may be too low for some applications. There were serious problems with the reliability of operation of the pre production EPDs used in these tests. 9 refs., 34 tabs., 20 figs

The Savannah River Site`s groundwater monitoring program. Third quarter 1990

Energy Technology Data Exchange (ETDEWEB)

1991-05-06

The Environmental Protection Department/Environmental Monitoring Section (EPD/EMS) administers the Savannah River Site`s (SRS) Groundwater Monitoring Program. During third quarter 1990 (July through September) EPD/EMS conducted routine sampling of monitoring wells and drinking water locations. EPD/EMS established two sets of flagging criteria in 1986 to assist in the management of sample results. The flagging criteria do not define contamination levels; instead they aid personnel in sample scheduling, interpretation of data, and trend identification. The flagging criteria are based on detection limits, background levels in SRS groundwater, and drinking water standards. All analytical results from third quarter 1990 are listed in this report, which is distributed to all site custodians. One or more analytes exceeded Flag 2 in 87 monitoring well series. Analytes exceeded Flat 2 for the first since 1984 in 14 monitoring well series. In addition to groundwater monitoring, EPD/EMS collected drinking water samples from SRS drinking water systems supplied by wells. The drinking water samples were analyzed for radioactive constituents.

Electrophoretic deposition of PEEK-TiO 2 composite coatings on stainless steel

KAUST Repository

Seuß, Sigrid

2012-03-01

Electrophoretic deposition (EPD) has been successfully used to deposit composite coatings composed of polyetheretherketone (PEEK) and titanium dioxide (TiO 2) nanoparticles on 316L stainless steel substrates. The suspensions of TiO2 nanoparticles and PEEK microparticles for EPD were prepared in ethanol. PEEK-TiO 2 composite coatings were optimized using suspensions containing 6wt% PEEK-TiO 2 in ethanol with a 3:1 ratio of PEEK to TiO 2 in weight and by applying a potential difference of 30 V for 1 minute. A heat-treatment process of the optimized PEEK-TiO 2 composite coatings was erformed at 335°C for 30 minutes with a heating rate of 10°Cmin -1 to densify the deposits. The EPD coatings were microstructurally evaluated by scanning electron microscopy (SEM). It was demonstrated that EPD is a convenient and rapid method to fabricate PEEK/TiO 2 coatings on stainless steel which are interesting for biomedical applications. © (2012) Trans Tech Publications, Switzerland.

Full Text Available Abstract Background Edinburgh Postnatal Depression Scale (EPDS is an important screening instrument that is used routinely with mothers during the postpartum period for early identification of postnatal depression. The purpose of this study was to validate the Greek version of EPDS along with sensitivity, specificity and predictive values. Methods 120 mothers within 12 weeks postpartum were recruited from the perinatal care registers of the Maternity Departments of 4 Hospitals of Heraklion municipality, Greece. EPDS and Beck Depression Inventory-II (BDI-II surveys were administered in random order to the mothers. Each mother was diagnosed with depression according to the validated Greek version of BDI-II. The psychometric measurements that were performed included: two independent samples t-tests, One-way analysis of variance (ANOVA, reliability coefficients, Explanatory factor analysis using a Varimax rotation and Principal Components Method. Confirmatory analysis -known as structural equation modelling- of principal components was conducted by LISREL (Linear Structural Relations. A receiver operating characteristic (ROC analysis was carried out to evaluate the global functioning of the scale. Results 8 (6.7% of the mothers were diagnosed with major postnatal depression, 14 (11.7% with moderate and 38 (31.7% with mild depression on the basis of BDI-II scores. The internal consistency of the EPDS Greek version -using Chronbach's alpha coefficient- was found 0.804 and that of Guttman split-half coefficient 0.742. Our findings confirm the multidimensionality of EPDS, demonstrating a two-factor structure which contained subscales reflecting depressive symptoms and anxiety. The Confirmatory Factor analysis demonstrated that the two factor model offered a very good fit to our data. The area under ROC curve AUC was found 0.7470 and the logistic estimate for the threshold score of 8/9 fitted the model sensitivity at 76.7% and model specificity at 68

Few studies are available on the effectiveness of screening tools such as the Edinburgh Postnatal Depression Scale (EPDS) in pregnancy or the extent to which such tools may identify women with mental disorders other than depression. We therefore aimed to investigate the mental health characteristics of pregnant women who screen positive on the EPDS. Consecutive women receiving antenatal care in primary care clinics (from November 2006 to July 2011) were invited to complete the EPDS in week 16 of pregnancy. All women who scored above 11 (screen positive) on the EPDS and randomly selected women who scored below 12 (screen negative) were invited to participate in a psychiatric diagnostic interview. 2,411 women completed the EPDS. Two hundred thirty-three women (9.7%) were screened positive in week 16, of whom 153 (66%) agreed to a psychiatric diagnostic interview. Forty-eight women (31.4%) were diagnosed with major depressive disorder according to DSM-IV criteria, 20 (13.1%) with bipolar disorder, 93 (60.8%) with anxiety disorders (including 27 [17.6%] with obsessive-compulsive disorder [OCD]), 8 (5.2%) with dysthymia, 18 (11.8%) with somatoform disorder, 3 (2%) with an eating disorder, and 7 (4.6%) with current substance abuse. Women who screened positive were significantly more likely to have psychosocial risk factors, including being unemployed (χ(2)(1) = 23.37, P ≤.001), lower educational status (χ(2)(1)= 31.68, P ≤ .001), and a history of partner violence (χ(2)(1) = 10.30, P ≤ 001), compared with the women who screened negative. Use of the EPDS early in the second trimester of pregnancy identifies a substantial number of women with potentially serious mental disorders other than depression, including bipolar disorder, OCD, and eating disorders. A comprehensive clinical assessment is therefore necessary following use of the EPDS during pregnancy to ensure that women who screen positive receive appropriate mental health management. © Copyright 2014

Fisher, R.E.; Boyd, G.A.; Breed, W.S.

1991-01-01

The National Energy Strategy Environmental Model (NESEAM) has been developed to project emissions for the National Energy Strategy (NES). Two scenarios were evaluated for the NES, a Current Policy Base Case and a NES Action Case. The results from the NES Actions Case project much lower emissions than the Current Policy Base Case. Future enhancements to NESEAM will focus on fuel cycle analysis, including future technologies and additional pollutants to model. NESEAM's flexibility will allow it to model other future legislative issues. 7 refs., 4 figs., 2 tabs

Herein we described the synthesis of siRNA-NES (nuclear export signal) peptide conjugates by solid phase fragment coupling and the application of them to silencing of bcr/abl chimeric gene in human chronic myelogenous leukemia cell line K562. Two types of siRNA-NES conjugates were prepared, and both sense strands at 5' ends were covalently linked to a NES peptide derived from TFIIIA and HIV-1 REV, respectively. Significant enhancement of silencing efficiency was observed for both of them. siRNA-TFIIIA NES conjugate suppressed the expression of BCR/ABL gene to 8.3% at 200 nM and 11.6% at 50 nM, and siRNA-HIV-1REV NES conjugate suppressed to 4.0% at 200 nM and 6.3% at 50 nM, whereas native siRNA suppressed to 36.3% at 200 nM and 30.2% at 50 nM. We could also show complex of siRNA-NES conjugate and designed amphiphilic peptide peptideβ7 could be taken up into cells with no cytotoxicity and showed excellent silencing efficiency. We believe that the complex siRNA-NES conjugate and peptideβ7 is a promising candidate for in vivo use and therapeutic applications.

Correlation between Gas Bubble Formation and Hydrogen Evolution Reaction Kinetics at Nanoelectrodes.

Chen, Qianjin; Luo, Long

2018-04-17

We report the correlation between H 2 gas bubble formation potential and hydrogen evolution reaction (HER) activity for Au and Pt nanodisk electrodes (NEs). Microkinetic models were formulated to obtain the HER kinetic information for individual Au and Pt NEs. We found that the rate-determining steps for the HER at Au and Pt NEs were the Volmer step and the Heyrovsky step, respectively. More interestingly, the standard rate constant ( k 0 ) of the rate-determining step was found to vary over 2 orders of magnitude for the same type of NEs. The observed variations indicate the HER activity heterogeneity at the nanoscale. Furthermore, we discovered a linear relationship between bubble formation potential ( E bubble ) and log( k 0 ) with a slope of 125 mV/decade for both Au and Pt NEs. As log ( k 0 ) increases, E bubble shifts linearly to more positive potentials, meaning NEs with higher HER activities form H 2 bubbles at less negative potentials. Our theoretical model suggests that such linear relationship is caused by the similar critical bubble formation condition for Au and Pt NEs with varied sizes. Our results have potential implications for using gas bubble formation to evaluate the HER activity distribution of nanoparticles in an ensemble.

2012-01-01

Cognitive reserve is invoked to explain the protective effects of education and cognitively-stimulating activities against all-cause dementia and Alzheimer’s disease (AD). For non-native English speakers (n-NES), speaking English may be a cognitive activity associated with lower dementia risk. We hypothesized that n-NES have lower risk of incident dementia/AD and that educational level might modify this relationship. Participants took part in the Einstein Aging Study (Bronx, NY), a longitudinal study of aging and dementia. All (n = 1779) spoke fluent English and self-reported birthplace and whether English was their first language. n-NES additionally reported mother tongue, age of English acquisition, and current percentile-use of a non-English language. Nested Cox proportional hazards models progressively adjusted for gender, race, education, and immigrant and marital status estimated hazard ratios (HR) for incident dementia/AD as a function of n-NES status. 390 (22%) participants were n-NES. 126 incident dementia cases occurred during 4174 person-years of follow-up (median 1.44; range 0–16); 101 individuals met criteria for probable/possible AD. There was no statistically-significant association between n-NES status and incident dementia in the fully-adjusted model (HR 1.26; 95% CI 0.76–2.09; p = 0.36). Results were similar for AD. Stratification of education into three groups revealed increased risk of dementia for n-NES with ≥16 years of education (HR 3.97; 95% CI 1.62–9.75; p = 0.003). We conclude that n-NES status does not appear to have an independent protective effect against incident dementia/AD, and that n-NES status may contribute to risk of dementia in an education-dependent manner.

2016-12-01

The prevalence of night-eating syndrome (NES) and depression is increasing worldwide. Although nurses, in particular, are exposed to work in an environment of irregular eating, shift work, and stressful settings, limited research exist. In fact, the prevalence of NES among Korean nurses has never been reported. The aim of this study was to determine the prevalence of NES as well as the association between NES and severity of self-reported depressive symptoms among South Korean female nurses. The Korea Nurses' Health Study, following the protocols of the Nurses' Health Study led by the Harvard University, collected data on Korean female nurses. Survey responses from 3617 participants were included, and 404 responses were analyzed in this cross-sectional study using propensity score matching. Descriptive, Spearman's and Cramer's correlations, propensity score matching, and multivariable ordinal logistic regression were conducted as statistical analysis. The prevalence of both NES and self-reported depressive symptoms among Korean female nurses were higher compared with nurses in prior studies. Nurses with NES were 1.65 times more likely to have greater severity of depressive symptoms than those without NES (95% confidence interval [1.19-2.10], odds ratio = 1.65) after adjusting for covariates including sociodemographic characteristics, health behavioural factors, and shift work. This study suggests significant association between NES and the severity of self-reported depressive symptoms among Korean female nurses after adjusting for covariates. Policy makers and hospital managers need to develop strategies to reduce depression and NES among nurses for enhancement of nurses' mental and physical health as well as for improvement of care quality.

Integration of Geometrical and Material Nonlinear Energy Sink with Piezoelectric Material Energy Harvester

Directory of Open Access Journals (Sweden)

Ye-Wei Zhang

2017-01-01

Full Text Available This paper presents a novel design by integrating geometrical and material nonlinear energy sink (NES with a piezoelectric-based vibration energy harvester under shock excitation, which can realize vibration control and energy harvesting. The nonlinear spring and hysteresis behavior of the NES could reflect geometrical and material nonlinearity, respectively. Two configurations of the piezoelectric device, including the piezoelectric element embedded between the NES mass and the single-degree-of-freedom system or ground, are utilised to examine the energy dissipated by damper and hysteresis behavior of NES and the energy harvested by the piezoelectric element. Similar numerical research methods of Runge-Kutta algorithm are used to investigate the two configurations. The energy transaction measure (ETM is adopted to examine the instantaneous energy transaction between the primary and the NES-piezoelectricity system. And it demonstrates that the dissipated and harvested energy transaction is transferred from the primary system to the NES-piezoelectricity system and the instantaneous transaction of mechanical energy occupies a major part of the energy of transaction. Both figurations could realize vibration control efficiently.

Full Text Available Francesca Anzellotti, Raffaella Franciotti, Holta Zhuzhuni, Aurelio D'Amico, Astrid Thomas, Marco Onofrj Department of Neuroscience and Imaging, Aging Research Centre, Gabriele d'Annunzio University Foundation, Gabriele d'Annunzio University, Chieti, Italy Abstract: Nonepileptic seizures (NES apparently look like epileptic seizures, but are not associated with ictal electrical discharges in the brain. NES constitute one of the most important differential diagnoses of epilepsy. They have been recognized as a distinctive clinical phenomenon for centuries, and video/electroencephalogram monitoring has allowed clinicians to make near-certain diagnoses. NES are supposedly unrelated to organic brain lesions, and despite the preponderance of a psychiatric/psychological context, they may have an iatrogenic origin. We report a patient with NES precipitated by levetiracetam therapy; in this case, NES was observed during the disappearance of epileptiform discharges from the routine video/electroencephalogram. We discuss the possible mechanisms underlying NES with regard to alternative psychoses associated with the phenomenon of the forced normalization process. Keywords: nonepileptic seizures, forced normalization, levetiracetam, behavioral side effects

Effects of linear and nonlinear time-delayed feedback on the noise-enhanced stability phenomenon in a periodically driven bistable system

International Nuclear Information System (INIS)

Jia, Zheng-Lin; Mei, Dong-Cheng

2011-01-01

We investigate numerically the effects of time delay on the phenomenon of noise-enhanced stability (NES) in a periodically modulated bistable system. Three types of time-delayed feedback, including linear delayed feedback, nonlinear delayed feedback and global delayed feedback, are considered. We find a non-monotonic behaviour of the mean first-passage time (MFPT) as a function of the delay time τ, with a maximum in the case of linear delayed feedback and with a minimum in the case of nonlinear delayed feedback. There are two peculiar values of τ around which the NES phenomenon is enhanced or weakened. For the case of global delayed feedback, the increase of τ always weakens the NES phenomenon. Moreover, we also show that the amplitude A and the frequency Ω of the periodic forcing play an opposite role in the NES phenomenon, i.e. the increase of A weakens the NES effect while the increase of Ω enhances it. These observations demonstrate that the time-delayed feedback can be used as a feasible control scheme for the NES phenomenon

The empirical phase diagram (EPD) is a colored representation of overall structural integrity and conformational stability of macromolecules in response to various environmental perturbations. Numerous proteins and macromolecular complexes have been analyzed by EPDs to summarize results from large data sets from multiple biophysical techniques. The current EPD method suffers from a number of deficiencies including lack of a meaningful relationship between color and actual molecular features, difficulties in identifying contributions from individual techniques, and a limited ability to be interpreted by color-blind individuals. In this work, three improved data visualization approaches are proposed as techniques complementary to the EPD. The secondary, tertiary, and quaternary structural changes of multiple proteins as a function of environmental stress were first measured using circular dichroism, intrinsic fluorescence spectroscopy, and static light scattering, respectively. Data sets were then visualized as (1) RGB colors using three-index EPDs, (2) equiangular polygons using radar charts, and (3) human facial features using Chernoff face diagrams. Data as a function of temperature and pH for bovine serum albumin, aldolase, and chymotrypsin as well as candidate protein vaccine antigens including a serine threonine kinase protein (SP1732) and surface antigen A (SP1650) from S. pneumoniae and hemagglutinin from an H1N1 influenza virus are used to illustrate the advantages and disadvantages of each type of data visualization technique.

2012-12-01

Equine periodontal disease (EPD) is a common and painful condition, the aetiology and pathology of which are poorly understood. To characterise the histopathological lesions associated with EPD, the skulls of 22 horses were assessed grossly for the presence of periodontal disease, and a standard set of interdental tissues taken from each for histopathological examination. Histological features of EPD included ulceration and neutrophilic inflammation of the gingival epithelium. Mononuclear and eosinophilic inflammation of the gingival lamina propria and submucosa was commonly present irrespective of the presence or degree of periodontal disease. Gingival hyperplasia was present to some degree in all horses, and was only weakly associated with the degree of periodontal disease. In all horses dental plaque was present at the majority of sites examined and was often associated with histological evidence of peripheral cemental erosion. Bacteria (including spirochaetes in four horses) were identified in gingival samples by Gram and silver impregnation techniques and were significantly associated with the presence of periodontal disease. This is the first study to describe histological features of EPD, and the first to identify associated spirochaetes in some cases. Histological features were variable, and there was considerable overlap of some features between the normal and diseased gingiva. Further investigation into the potential role of bacteria in the pathogenesis and progression of EPD is warranted. Copyright © 2012 Elsevier Ltd. All rights reserved.

[Effect of paternity leave on maternal postpartum depression].

The aim of this study was to explore the role of the paternity leave in the appearance of the maternal postpartum depression. Fifty-one couples took part in the whole study. Between the second and the fifth day after the childbirth, the mother completed the Edinburgh Postnatal Depression Scale (EPDS), which measures the symptoms of depression and the Multidimensional Scale of Perceived Social Support (MSPSS) which measures the social support the mother has become. The father completed the EPDS. Two months and then the second time four months after the childbirth, the mother received the EPDS, the MSPSS, and questionnaires measuring the temperament of the baby, the maternal skills, the feeling of being a mother and the quality of life postpartum. In order to evaluate the paternal involvement, the father completed the EPDS and questions about paternal skills and involvement. The paternity leave seemed not to have any consequences on the results at the EPDS or other questionnaires. However, lack of paternal involvement was a significant predictor of the intensity of the depressive symptoms of the mothers. It is not the presence of the father wich seems important to take into account for detection and the traitement of postpatum depression but his participation in the care of the baby.

Full Text Available Le but de cette étude est la connaissance qualitative et quantitative des composés dégagés lors de la décomposition thermique sous vide de quelques échantillons de kérogènes appartenant à deux lignées différentes. La principale technique utilisée est la spectrométrie de masse, appuyée sur des études préliminaires par thermogravi métrie et analyse élémentaire. Une adaptation particulière de l'appareillage et une mise au point de la méthode d'étalonnage permettent de doser les quatre composés minéraux les plus abondants et de donner une représentation des composés organiques. Cette étude montre que les composés formés au cours du chauffage comprennent, pour tous les kérogènes étudiés, des composés oxygénés et soufrés (CO, H2O, SH2, SOJ libérés principalement dans l'intervalle de température 200-400° C, et des composés hydrocarbonés, plus abondants, dans l'intervalle 300-500° C. On commente dans cet article l'origine supposée de ces composés; la formation de S02 au cours de la pyrolyse est particulièrement mal connue. On remarque que le rapport H2O/C02 peut être un critère de distinction des deux lignées de kérogènes étudiés. La distinction observée sur les produits hydrocarbonés nécessitera des recherches complémentaires pour être utilisée avec plus de sûreté. The aim of this investigation is to obtain a qualitative and quantitative understanding of the compounds given off during the vacuum thermal decomposition of several kerogen samples from two different lines. The main technique used is mass spectrometry, based on prior investigations by thermogravimetry and element onalysis. The equipment was specially adapted and a calibration method was developed for titrating the four most abundant minerai compounds and for representing the organic compounds. This investigation shows that the compounds formed during heating include, for oil the kerogens examined, oxygen-and sulfur

Involvement of extracellular factors in maintaining self-renewal of neural stem cell by nestin.

Nestin knockout leads to embryonic lethality and self-renewal deficiency in neural stem cells (NSCs). However, how nestin maintains self-renewal remains uncertain. Here, we used the dosage effect of nestin in heterozygous mice (Nes+/-) to study self-renewal of NSCs. With existing extracellular signaling in vivo or in vitro, nestin levels do not affect proliferation ability or apoptosis when compared between Nes+/- and Nes+/+ NSCs. However, self-renewal ability of Nes+/- NSCs is impaired when plated at a low cell density and completely lost at a clonal density. This deficiency in self-renewal at a clonal density is rescued using a medium conditioned by Nes+/+ NSCs. In addition, the Akt signaling pathway is altered at low density and reversed by conditioned medium. Our data show that secreted factors contribute toward maintaining self-renewal of NSCs by nestin, potentially through Akt signaling.

Night eating syndrome: How to treat it?

Directory of Open Access Journals (Sweden)

Thisciane Ferreira Pinto

Full Text Available Summary Night eating syndrome (NES is characterized by caloric intake ≥ 25% of total daily after dinner and/or by two or more weekly nocturnal awakenings accompanied by food ingestion. Causes of NES are not entirely clear and seem to involve a desynchronization between the circadian rhythms of food ingestion and sleep, resulting in a delayed pattern of food intake. Estimates of the prevalence of NES in the general population are around 1.5%, and although much higher frequencies have been described in obese individuals, a causal relationship between NES and obesity is not clearly established. Since the first NES reports, several treatment modalities have been proposed, although, in many cases, the evidence is still insufficient and there is no consensus on the ideal approach. In order to conduct a critical review of proposed treatments for NES since its original description, a systematic search of articles published in journals indexed in Medline/Pubmed database in the period 1955-2015 was performed. Seventeen articles addressing non-pharmacological and pharmacological therapies met the selection criteria. Based on the articles analyzed, we conclude that serotonergic agents and psychological interventions, particularly cognitive behavioral therapy, have been shown to be effective for the treatment of NES. A combination of non-pharmacological and pharmacological therapies must be considered in future studies on the treatment of these patients.

Agomelatine Efficacy in the Night Eating Syndrome

Directory of Open Access Journals (Sweden)

Walter Milano

2013-01-01

Full Text Available Night eating syndrome (NES is a nosographic entity included among the forms not otherwise specified (EDNOS in eating disorders (ED of the DSM IV. It is characterized by a reduced food intake during the day, evening hyperphagia, and nocturnal awakenings associated with conscious episodes of compulsive ingestion of food. Frequently, NES patients show significant psychopathology comorbidity with affective disorders. This paper describes a case report of an NES patient treated with agomelatine, an antidepressant analogue of melatonin, which acts by improving not only the mood but also by regulating sleep cycles and appetite. After three months of observation, the use of Agomelatine not only improved the mood of our NES patient (assessed in the HAM-D scores but it was also able to reduce the night eating questionnaire, by both reducing the number of nocturnal awakenings with food intake, the time of snoring, the minutes of movement during night sleep (assessed at polysomnography, and the weight (−5.5 kg and optimizing blood glucose and lipid profile. In our clinical case report, agomelatine was able both to reduce the NES symptoms and to significantly improve the mood of our NES patient without adverse side effects during the duration of treatment. Therefore, our case report supports the rationale for further studies on the use of Agomelatine in the NES treatment.

Impuretés et systèmes corrélés. Des chaînes aux cuprates supraconducteurs

Impurities and correlated systems Discovery of high TC superconductors has opened the new field of strongly correlated fermions physics. In these compounds, mostly transition metal oxides, strong correlations between electrons affect sharply their electronic properties. In order to determine accurately these correlations and their possible link with superconductivity, we study the effect of local defects such as non magnetic impurities. In fact, in the more simple case of insulating spin chains and ladders, these impurities induce a staggered magnetism in their neighborhood which reveals the underlying electronic correlations. Similar effects are observed in high TC superconductors, using local probes such as nuclear magnetic resonance. These observations allow to get a better understanding of both normal and superconducting state of these oxides, both full of surprises. La découverte des supraconducteurs à haute température critique a ouvert la voie à une nouvelle physique, celle des fermions fortement corrélés. Dans ces systèmes, le plus souvent des oxydes de métaux de transition, les fortes corrélations entre électrons affectent profondément leurs propriétés électroniques et induisent de nouveaux états originaux : liquides de spins, supraconductivité, etc. Pour mesurer ces corrélations et ainsi déterminer leur lien éventuel avec la supraconductivité, nous proposons d'étudier l'effet de défauts ponctuels tels que des impuretés non magnétiques. En effet, dans le cas plus simple de chaînes ou d'échelles de spin isolantes, ces impuretés induisent dans leur voisinage immédiat un magnétisme alterné révélateur des corrélations électroniques. Des effets semblables sont observés dans les supraconducteurs à haute température critique, grâce à des sondes locales comme la résonance magnétique nucléaire. Ces observations permettent de mieux comprendre à la fois l'état normal et supraconducteur de ces oxydes, tous deux riches en

Full Text Available Abstract Objectives 1 to evaluate the role of the pediatrician in detecting postnatal depression (PD symptoms by the Edinburgh Postnatal Depression Scale (EPDS; 2 to detect factors increasing the risk of PD and, 3 to assess the importance of scores gained from fathers' questionnaire. Methods we surveyed 1122 mothers and 499 fathers who were assessed using the EPDS during the first well-child visit. After 5 weeks, high scoring parents, completed a second EPDS. High scoring parents were examined by a psychiatrist who had to confirm the PD diagnosis. Results 26.6% of mothers and 12.6% of fathers at the first visit, 19.0% of mothers and 9.1% of fathers at the second visit, gained scores signaling the risk of PD. Four mothers and two fathers had confirmed PD diagnosis. Younger maternal age, non-Italian nationality and low socio-economic condition were related to higher EPDS scores. Conclusion PD is common in the average population. Using a simple and standardized instrument, pediatricians are able to detect parents with higher risk of suffering from PD.

1991-05-06

The Environmental Protection Department/Environmental Monitoring Section (EPD/EMS) administers the Savannah River Site's (SRS) Groundwater Monitoring Program. During third quarter 1990 (July through September) EPD/EMS conducted routine sampling of monitoring wells and drinking water locations. EPD/EMS established two sets of flagging criteria in 1986 to assist in the management of sample results. The flagging criteria do not define contamination levels; instead they aid personnel in sample scheduling, interpretation of data, and trend identification. The flagging criteria are based on detection limits, background levels in SRS groundwater, and drinking water standards. All analytical results from third quarter 1990 are listed in this report, which is distributed to all site custodians. One or more analytes exceeded Flag 2 in 87 monitoring well series. Analytes exceeded Flat 2 for the first since 1984 in 14 monitoring well series. In addition to groundwater monitoring, EPD/EMS collected drinking water samples from SRS drinking water systems supplied by wells. The drinking water samples were analyzed for radioactive constituents.

Binge-eating disorder (BED) as a distinct eating disorder category and night eating syndrome (NES) as a form of Other Specified Feeding or Eating Disorders were recently included in the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). This study sought to investigate the prevalence of BED and NES and associations with various forms of nonnormative eating behavior and psychopathology in prebariatric patients. Within a consecutive multicenter registry study, patients in 6 bariatric surgery centers in Germany were recruited. Overall, 233 prebariatric patients were assessed using the Eating Disorder Examination and self-report questionnaires. Assessment was unrelated to clinical procedures. Diagnostic criteria for full-syndrome BED and NES were currently met by 4.3% and 8.2% of prebariatric patients, respectively. In addition, 8.6% and 6.9% of patients met subsyndromal BED and NES criteria, respectively. Co-morbid BED and NES diagnoses were present in 3.9% of patients. In comparison to patients without any eating disorder symptoms, patients with BED and NES reported greater emotional eating, eating in the absence of hunger, and more symptoms of food addiction. Moreover, differences between patients with BED and NES emerged with more objective binge-eating episodes and higher levels of eating concern, weight concern, and global eating disorder psychopathology in patients with BED. BED and NES were shown to be prevalent among prebariatric patients, with some degree of overlap between diagnoses. Associations with nonnormative eating behavior and psychopathology point to their clinical significance and discriminant validity. Copyright © 2015 American Society for Bariatric Surgery.

Highlights: ► We found the putative nuclear export signal motif within human NANOG homeodomain. ► Leucine-rich residues are important for human NANOG homeodomain nuclear export. ► CRM1-specific inhibitor LMB blocked the potent human NANOG NES-mediated nuclear export. -- Abstract: NANOG is a homeobox-containing transcription factor that plays an important role in pluripotent stem cells and tumorigenic cells. To understand how nuclear localization of human NANOG is regulated, the NANOG sequence was examined and a leucine-rich nuclear export signal (NES) motif ( 125 MQELSNILNL 134 ) was found in the homeodomain (HD). To functionally validate the putative NES motif, deletion and site-directed mutants were fused to an EGFP expression vector and transfected into COS-7 cells, and the localization of the proteins was examined. While hNANOG HD exclusively localized to the nucleus, a mutant with both NLSs deleted and only the putative NES motif contained (hNANOG HD-ΔNLSs) was predominantly cytoplasmic, as observed by nucleo/cytoplasmic fractionation and Western blot analysis as well as confocal microscopy. Furthermore, site-directed mutagenesis of the putative NES motif in a partial hNANOG HD only containing either one of the two NLS motifs led to localization in the nucleus, suggesting that the NES motif may play a functional role in nuclear export. Furthermore, CRM1-specific nuclear export inhibitor LMB blocked the hNANOG potent NES-mediated export, suggesting that the leucine-rich motif may function in CRM1-mediated nuclear export of hNANOG. Collectively, a NES motif is present in the hNANOG HD and may be functionally involved in CRM1-mediated nuclear export pathway.

Miller, Renée L; Pallant, Julie F; Negri, Lisa M

2006-03-24

Postnatal depression has received considerable research and clinical attention, however anxiety and stress in the postpartum has been relatively ignored. Along with the widespread use of the Edinburgh Postnatal Depression Scale (EPDS), depression has become the marker for postnatal maladjustment. Symptoms of anxiety tend to be subsumed within diagnoses of depression, which can result in anxiety being minimized or overlooked in the absence of depression. Some researchers have identified the need to distinguish between postnatal depression and anxiety, and to discern cases where depression and anxiety co-exist. The aim of this study was to assess the prevalence of postnatal distress using the EPDS and the Depression Anxiety Stress Scales (DASS-21). As part of a larger cross-sectional study, the EPDS and DASS-21 were administered to a convenience sample of 325 primiparous mothers, who ranged in age from 18 to 44 years (M = 32 years). Recruited through mother's groups and health centres in Melbourne Australia, inclusion was limited to mothers whose babies were aged between 6 weeks and 6 months. Analyses included comparisons between the classifications of women according to the EPDS and the DASS-21, and an exploration of the extent to which the EPDS identified anxious-depressed women. The EPDS identified 80 women (25%) as possibly depressed (using a cut-off of over 9), of which the DASS-21 corroborated 58%. In the total sample, 61 women (19%) were classified by the DASS-21 to be depressed. Using broader criteria for distress, it was revealed by the DASS-21 that a further 33 women (10%) showed symptoms of anxiety and stress without depression. A total of 41 women (13%) had symptoms of anxiety either in isolation or in combination with depression. The DASS-21 identified 7% of the sample as being both anxious and depressed. This at-risk sub-group had higher mean EPDS and DASS-depression scores than their depressed-only counterparts. The prevalence of anxiety and stress in

Full Text Available 1 Abstract 1.1 Background Suicide is a leading cause of perinatal maternal deaths in industrialised countries but there has been little research to investigate prevalence or correlates of postpartum suicidality. The Edinburgh Postnatal Depression Scale is widely used in primary and maternity services to screen for perinatal depressive disorders, and includes a question on suicidal ideation (question 10. We aimed to investigate the prevalence, persistence and correlates of suicidal thoughts in postpartum women in the context of a randomised controlled trial of treatments for postnatal depression. 1.2 Methods Women in primary care were sent postal questionnaires at 6 weeks postpartum to screen for postnatal depression before recruitment into an RCT. The Edinburgh Postnatal Depression Scale (EPDS was used to screen for postnatal depression and in those with high levels of symptoms, a home visit with a standardised psychiatric interview was carried out using the Clinical Interview Schedule-Revised version (CIS-R. Other socio-demographic and clinical variables were measured, including functioning (SF12 and quality of the marital relationship (GRIMS. Women who entered the trial were followed up for 18 weeks. 1.3 Results 9% of 4,150 women who completed the EPDS question relating to suicidal ideation reported some suicidal ideation (including hardly ever; 4% reported that the thought of harming themselves had occurred to them sometimes or quite often. In women who entered the randomised trial and completed the EPDS question relating to suicidal ideation (n = 253, suicidal ideation was associated with younger age, higher parity and higher levels of depressive symptoms in the multivariate analysis. Endorsement of 'yes, quite often' to question 10 on the EPDS was associated with affirming at least two CIS-R items on suicidality. We found no association between suicidal ideation and SF-12 physical or mental health or the EPDS total score at 18 weeks. 1

Full Text Available This work deals with the design and experiment of a cubic nonlinear energy sink (NES for horizontal vibration mitigation of a bridge cable. Modal analysis of horizontal linear modes of the cable is experimentally performed using accelerometers and displacement sensors. A theoretical simplified 2-dof model of the coupled cable-NES system is used to analytically design the NES by mean of multi-time scale systems behaviours and detection its invariant manifold, equilibrium and singular points which stand for periodic and strongly modulated regimes, respectively. Numerical integration is used to confirm the efficiency of the designed NES for the system under step release excitation. Then, the prototype system is built using geometrical cubic nonlinearity as the potential of the NES. Efficiency of the prototype system for mitigation of horizontal vibrations of the cable under for step release and forced excitations is experimentally demonstrated.

Long-term follow-up and risk factors of persistent post-partum depression (PPD) are fairly unknown compared with its prevalence in the developing countries. In this study, we did a follow-up measure of PPD and examined the factors, which were associated with PPD 1-year post-partum. Our sample comprised of 34 women. Depressive symptoms were assessed by the Edinburgh post-natal depression scale (EPDS) 6 weeks post-partum, and women with scores >12 on this scale was categorised as depressed. Personality disorders were determined at the same occasion by means of the Structured Clinical Interview for DSM-III-R personality disorders (SCID-II). One year post-partum EPDS was completed. The rate of PPD 1-year post-partum was 32.4%, and it was unrelated to age at assessment, primiparity, number of children, employment status, economical status and educational level. Women depressed 1-year post-partum had significantly higher basal scores of EPDS and more often also a diagnosis of any axis II disorder; and specifically dependent and obsessive-compulsive personality disorders. In our sample, the predictors of 1-year post-partum PPD were having higher basal score of EPDS and the existence of a personality disorder. This study suggests that women with PPD, scoring high in the EPDS scale 6 weeks post-partum and having a personality disorder, run a higher risk for depression at 1-year follow-up.

Eight (8) mol% yttria stabilized zirconia (YSZ), an electrolyte material for solid oxide fuel cell (SOFC), has been deposited onto porous non-conducting NiO-YSZ substrate using electrophoretic deposition technique (EPD) from a stable non-aqueous suspension of YSZ. Normally, EPD cannot be performed on a non-conducting substrate, but, in this present study, YSZ particulate film has been successfully deposited on a non-conducting NiO-YSZ substrate following two different EPD approaches:(a) using a conducting metallic plate on the reverse side of the porous NiO-YSZ anode substrate and (b) using a conducting polymer coated NiO-YSZ substrate. The deposited films are then formed dense coatings of 5-15 μm after sintering at 1400℃ for 6 h in air. Surface and cross-sectional morphologies of green and sintered films deposited by different EPD approaches are investigated using SEM. La 0.65 Sr 0.3 MnO 3 (LSM), a cathode for SOFC, is then screen-printed onto the electrolyte layer of such sintered half cells (anode+electrolyte) prepared by both the above approaches to construct SOFC single cells. A maximum output power density of 0.37 W.cm -2 is obtained using single cells prepared by conducting metallic plate assisted EPD compared to that of 0.73 W.cm -2 for polymer coated at 800℃ using H 2 as fuel and O 2 as oxidant.

Compact wireless control network protocol with fast path switching

Directory of Open Access Journals (Sweden)

Yasutaka Kawamoto

2017-08-01

Full Text Available Sensor network protocol stacks require the addition or adjustment of functions based on customer requirements. Sensor network protocols that require low delay and low packet error rate (PER, such as wireless control networks, often adopt time division multiple access (TDMA. However, it is difficult to add or adjust functions in protocol stacks that use TDMA methods. Therefore, to add or adjust functions easily, we propose NES-SOURCE, a compact wireless control network protocol with a fast path-switching function. NES-SOURCE is implemented using carrier sense multiple access/collision avoidance (CSMA/CA rather than TDMA. Wireless control networks that use TDMA prevent communication failure by duplicating the communication path. If CSMA/CA networks use duplicate paths, collisions occur frequently, and communication will fail. NES-SOURCE switches paths quickly when communication fails, which reduces the effect of communication failures. Since NES-SOURCE is implemented using CSMA/CA rather than TDMA, the implementation scale is less than one-half that of existing network stacks. Furthermore, since NES-SOURCE’s code complexity is low, functions can be added or adjusted easily and quickly. Communication failures occur owing to changes in the communication environment and collisions. Experimental results demonstrate that the proposed NES-SOURCE’s path-switching function reduces the amount of communication failures when the communication environment changes owing to human movement and others. Furthermore, we clarify the relationships among the probability of a changing communication environment, the collision occurrence rate, and the PER of NES-SOURCE.

The objectives of this study were: (1) to examine Composite International Diagnostic Interview (CIDI) period prevalence and comorbidity for depression and anxiety disorder in a cohort of women assessed during the first 6-8 months postpartum and (2) to examine the benefits of combining the Edinburgh Postnatal Depression Scale (EPDS) with a simple "interval symptom" question to optimize screening postpartum. Women aged over 18 (N = 1,549) were assessed during late pregnancy and reviewed at approximately 2, 4, and 6-8 months postpartum using the EPDS and an "interval symptom" question. The latter asked about any depressive symptoms in the interval since the last EPDS. Women who scored >12 on the EPDS and/or positive on the "interval symptom" question were then administered the CIDI. A further 65 randomly selected women that screened negative were also administered the CIDI. Loss to postnatal follow-up was very significant, and returns rates were inconsistent across the three postnatal time points. Almost 25% of those who screened positive did not complete a CIDI. For screen-positive status, a total of 314 (24.4%) of those that returned questionnaires (N = 1,289) screened positive at least once across the 6- to 8-month interval. Of these, 79 were lost to follow-up; thus, 235 (74.8%) completed a CIDI. In this group, 34.7% had been positive both on the EPDS and the "interval" question, 15.9% on the EPDS alone, and 49.4% on the "interval" question alone. For the CIDI diagnosis and estimated 6- to 8-month period CIDI prevalence, among those 235 women who screened positive and completed a CIDI, 67.2% met the criteria for a CIDI diagnosis, as did 16.9% of those who screened negative. The breakdown in CIDI diagnoses in the 235 women was 32.8% major depression (± anxiety disorder); 26.4% minor depression alone; and 8.1% with a primary anxiety disorder (approximately half with minor depression). Put another way, 20.4% of these women had an anxiety disorder

In this study, we fabricated and fully characterized a new type of polystyrene (PS) cell-culture platform containing nanoengineered surfaces (NES), referred to as a nano Petri dish, which can be used at the transition stage of basic cell–NES interaction studies for clinical applications. Nano-injection molding in this study was used for the mass production of the nano Petri dish having nanopore arrays. The effects of processing parameters of the injection molding on the replication quality of the nanopore arrays were quantitatively evaluated by means of design of experiments based on the Taguchi method. This allowed efficient and reliable cell culture studies by providing large numbers of the same dishes, in addition to removing the fixation step of the NES plates inside the cell-culture container. Physical, chemical and mechanical properties of the NES, as well as cell behavior including attachment and proliferation of human osteosarcoma MG-63 cells on the NES, were then characterized, with and without the oxygen plasma surface treatment.

Zika Virus Disrupts Phospho-TBK1 Localization and Mitosis in Human Neuroepithelial Stem Cells and Radial Glia

Full Text Available The mechanisms underlying Zika virus (ZIKV-related microcephaly and other neurodevelopment defects remain poorly understood. Here, we describe the derivation and characterization, including single-cell RNA-seq, of neocortical and spinal cord neuroepithelial stem (NES cells to model early human neurodevelopment and ZIKV-related neuropathogenesis. By analyzing human NES cells, organotypic fetal brain slices, and a ZIKV-infected micrencephalic brain, we show that ZIKV infects both neocortical and spinal NES cells as well as their fetal homolog, radial glial cells (RGCs, causing disrupted mitoses, supernumerary centrosomes, structural disorganization, and cell death. ZIKV infection of NES cells and RGCs causes centrosomal depletion and mitochondrial sequestration of phospho-TBK1 during mitosis. We also found that nucleoside analogs inhibit ZIKV replication in NES cells, protecting them from ZIKV-induced pTBK1 relocalization and cell death. We established a model system of human neural stem cells to reveal cellular and molecular mechanisms underlying neurodevelopmental defects associated with ZIKV infection and its potential treatment.

We examined serotonin transporter (SERT) binding affinity using single photon emission computed tomography (SPECT) in patients with major depressive disorder (MDD) and night eating syndrome (NES). There are similarities between MDD and NES in affective symptoms, appetite disturbance, nighttime awakenings, and, particularly, response to selective serotonin reuptake inhibitors (SSRIs). Six non-depressed patients with NES and seven patients with MDD underwent SPECT brain imaging with 123I-ADAM, a radiopharmaceutical agent selective for SERT sites. Uptake ratios of 123I-ADAM SERT binding were obtained for the midbrain, basal ganglia, and temporal lobe regions compared to the cerebellum reference region. Patients with NES had significantly greater SERT uptake ratios (effect size range 0.64-0.84) in the midbrain, right temporal lobe, and left temporal lobe regions than those with MDD whom we had previously studied. Pathophysiological differences in SERT uptake between patients with NES and MDD suggest these are distinct clinical syndromes.

The alkaline massif of Banhadao, located near Cerro Azul, State of Parana, southern Brazil, occupies an area of about 8 Km 2 and is constituted by three magnetic associations: a group of mesocratic to leucocratic coarse nepheline syenites (NeS) (melanite NeS, NeS I, and light reddish and grey varieties of NeS II); a second group of medium to fine-grained ultrabasic to basic rocks (phlogopite melteigites and petrologically related malignites and feldspar-melanite ijolites); and a group of fine-grained to aphanitic phonolotic dikes, cutting NeS. The rocks of the complex are miaskitic, showing low concentrations of trace elements (V, Th and mainly REE), lack of rare metal silicates, and relative abundance of apatite and sphene. NeS are distinguished by a differentiation trend in which highly differentiated end members are enriched in alkalis and Al 2 O 3 , with decrease in MgO, FeO (total), CaO and TiO 2 . The less differentiated melanite-rich rocks show higher concentrations in Zr, Nb, Y and V. Phlogopite melteigites and associated rocks show the highest contents of MgO, FeO (total), CaO and TiO 2 , and the lowest concentration of alkalis and Al 2 O 3 ; they are significantly enriched in Ba and are the only rocks with detectable amounts of Ni, Cu and Cr. The phonolites are chemically similar to NeS. The Banhadao rocks were probably formed during successive intrusions of two different magmas types. The source of NeS and phonolites was probably a nephelinitic magma, while phlogopite melteigites and related rocks were probably derived from an alkali-enriched ferromagnesian magna. Both parent magmas probably derived by melting of rocks of the lower crust or upper mantle. (author) [pt

The Savannah River Site's Groundwater Monitoring Program: Second quarter 1992

1992-10-07

The Environmental Protection Department/Environmental Monitoring Section (EPD/EMS) administers the Savannah River Site's (SRS) Groundwater Monitoring Program. During second quarter 1992, EPD/EMS conducted extensive sampling of monitoring wells. EPD/EMS established two sets of criteria to assist in the management of sample results. The flagging criteria do not define contamination levels; instead, they aid personnel in sample scheduling, interpretation of data, and trend identification. Since 1991, the flagging criteria have been based on the federal Environmental Protection Agency (EPA) drinking water standards and on method detection limits. A detailed explanation of the current flagging criteria is presented in the Flagging Criteria section of this document. Analytical results from second quarter 1992 are listed in this report.

Full Text Available Abstract Background The ETS family transcription factor ESE-1 is often overexpressed in human breast cancer. ESE-1 initiates transformation of MCF-12A cells via a non-transcriptional, cytoplasmic process that is mediated by a unique 40-amino acid serine and aspartic acid rich (SAR subdomain, whereas, ESE-1's nuclear transcriptional property is required to maintain the transformed phenotype of MCF7, ZR-75-1 and T47D breast cancer cells. Results To map the minimal functional nuclear localization (NLS and nuclear export (NES signals, we fused in-frame putative NLS and NES motifs between GFP and the SAR domain. Using these GFP constructs as reporters of subcellular localization, we mapped a single NLS to six basic amino acids (242HGKRRR247 in the AT-hook and two CRM1-dependent NES motifs, one to the pointed domain (NES1: 102LCNCALEELRL112 and another to the DNA binding domain (DBD, (NES2: 275LWEFIRDILI284. Moreover, analysis of a putative NLS located in the DBD (316GQKKKNSN323 by a similar GFP-SAR reporter or by internal deletion of the DBD, revealed this sequence to lack NLS activity. To assess the role of NES2 in regulating ESE-1 subcellular localization and subsequent transformation potency, we site-specifically mutagenized NES2, within full-length GFP-ESE-1 and GFP-NES2-SAR reporter constructs. These studies show that site-specific mutation of NES2 completely abrogates ESE-1 transforming activity. Furthermore, we show that exclusive cytoplasmic targeting of the SAR domain is sufficient to initiate transformation, and we report that an intact SAR domain is required, since block mutagenesis reveals that an intact SAR domain is necessary to maintain its full transforming potency. Finally, using a monoclonal antibody targeting the SAR domain, we demonstrate that the SAR domain contains a region accessible for protein - protein interactions. Conclusions These data highlight that ESE-1 contains NLS and NES signals that play a critical role in

This paper seeks to advance previous work including the effects of nuclear elastic scattering (NES) on fusion-product transport. We have found that NES may dominate the slowing-down process for high-temperature, advance-fuel plasmas which burn Cat.D or D- 3 He. A modified version of the Monte Carlo fusion product transport code, MCFRM, was used to evaluate the effects of NES on discrete fusion-product orbits in the FRM

Context: Combinations of testosterone (T) and nestorone (NES; a nonandrogenic progestin) transdermal gels may suppress spermatogenesis and prove appealing to men for contraception. Objective: The objective of the study was to determine the effectiveness of T gel alone or combined with NES gel in suppressing spermatogenesis. Design and Setting: This was a randomized, double-blind, comparator clinical trial conducted at two academic medical centers. Participants: Ninety-nine healthy male volunteers participated in the study. Interventions: Volunteers were randomized to one of three treatment groups applying daily transdermal gels (group 1: T gel 10 g + NES 0 mg/placebo gel; group 2: T gel 10 g + NES gel 8 mg; group 3: T gel 10 g + NES gel 12 mg). Main Outcome Variable: The main outcome variable of the study was the percentage of men whose sperm concentration was suppressed to 1 million/ml or less by 20–24 wk of treatment. Results: Efficacy data analyses were performed on 56 subjects who adhered to the protocol and completed at least 20 wk of treatment. The percentage of men whose sperm concentration was 1 million/ml or less was significantly higher for T + NES 8 mg (89%, P male range throughout the treatment period. Adverse effects were minimal in all groups. Conclusion: A combination of daily NES + T gels suppressed sperm concentration to 1 million/ml or less in 88.5% of men, with minimal adverse effects, and may be further studied as a male transdermal hormonal contraceptive.

Regulated nucleocytoplasmic transport of proteins is central to cellular function and dysfunction during processes such as viral infection. Active protein trafficking into and out of the nucleus is dependent on the presence within cargo proteins of intrinsic specific modular signals for nuclear import (nuclear localization signals, NLSs) and export (nuclear export signals, NESs). Rabies virus (RabV) phospho (P) protein, which is largely responsible for antagonising the host anti-viral response, is expressed as five isoforms (P1–P5). The subcellular trafficking of these isoforms is thought to depend on a balance between the activities of a dominant N-terminal NES (N-NES) and a distinct C-terminal NLS (C-NLS). Specifically, the N-NES-containing isoforms P1 and P2 are cytoplasmic, whereas the shorter P3–P5 isoforms, which lack the N-NES, are believed to be nuclear through the activity of the C-NLS. Here, we show for the first time that RabV P contains an additional strong NLS in the N-terminal region (N-NLS), which, intriguingly, overlaps with the N-NES. This arrangement represents a novel nuclear trafficking module where the N-NLS is inactive in P1 but becomes activated in P3, concomitant with truncation of the N-NES, to become the principal targeting signal conferring nuclear accumulation. Understanding this unique switch arrangement of overlapping, co-regulated NES/NLS sequences is vital to delineating the critical role of RabV P protein in viral infection. PMID:22700958

About 24.1% of pregnant women suffer from at least 1 anxiety disorder, 8.5% of whom suffer specifically from generalized anxiety disorder (GAD). GAD is often associated with major depressive disorder (MDD). During the perinatal period, the presence of physical and somatic symptoms often makes differentiation between depression and anxiety more challenging. To date, no screening tools have been developed to detect GAD in the perinatal population. We investigated the psychometric properties of the GAD 7-item Scale (GAD-7) as a screening tool for GAD in pregnant and postpartum women. Two hundred and forty perinatal women (n = 155 pregnant and n = 85 postpartum) referred for psychiatric consultation were enrolled. On the day of initial assessment, all women completed the GAD-7 and the Edinburgh Postnatal Depression Scale (EPDS). Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition-based diagnoses were made by experienced psychiatrists. Scores from the GAD-7 and EPDS were compared with the clinical diagnoses to evaluate the psychometric properties of the GAD-7 and EPDS when used as a screening tool for GAD. The GAD-7 yielded a sensitivity of 61.3% and specificity of 72.7% at an optimal cut-off score of 13. Compared with the EPDS and the EPDS-3A subscale, the GAD-7 displayed greater accuracy and specificity over a greater range of cut-off scores and more accurately identified GAD in patients with comorbid MDD. Our findings suggest that the GAD-7 represents a clinically useful scale for the detection of GAD in perinatal women.

Full Text Available Structures and phenomena occurring during the heat treatment of cornstarch. The structure of cornstarch and the modifications induced during the heat treatments are presented in this review. Current knowledge indicate that the starch granules are semi-crystalline entities composed mainly by amylose and amylopectin, undergoing deep reorganizations during the heat treatments. Gelatinization, glass transitions, relaxation phenomena, retrogradation and the formation of amylose-lipids complexes are the major phenomena involved in these reorganisations, and are the basis of changes of the techno-functional properties of cornstarch-based products during their heat treatment. La rhizosphère est le volume du sol situé au voisinage immédiat des racines des plantes et qui se caractérise par la présence d'exsudats racinaires (rhizodépôts. Ces exsudats sont utilisés par la microflore endémique en tant que signaux chimiques en plus d'être un substrat nutritif disponible pour la croissance et le développement de ces microorganismes dans la rhizosphère. Certaines de ces bactéries du sol, appelées PGPRs (Plant Growth Promoting Rhizobacteria, sont capables de coloniser les racines ou bien encore la rhizosphère, mais à la différence des autres bactéries rhizosphériques elles ont, en retour, un effet bénéfique sur la plante. Cet effet bénéfique peut être direct, ou indirect. La promotion directe de la croissance est le résultat du pouvoir d'acquisition des nutriments ou de la stimulation des hormones de la plante. D'autres mécanismes indirects, mais le plus souvent liés à la croissance des plantes, sont impliqués dans la réduction/suppression des pathogènes des plantes. Cet article décrit les différents mécanismes mis en jeu par les PGPRs dans leur environnement naturel pour influencer favorablement la croissance et la santé des plantes.

Full Text Available Abstract Background Information on clinical acceptability is needed when making cost-utility decisions about health screening implementation. Despite being in use for two decades, most data on the clinical acceptability of the Edinburgh Postnatal Depression Scale (EPDS come from qualitative reports, or include relatively small samples of depressed women. This study aimed to measure acceptability in a survey of a relatively large, community sample with a high representation of clinically depressed women. Methods Using mail, telephone and face-to-face interview, 920 postnatal women were approached to take part in a survey on the acceptability of the EPDS, including 601 women who had screened positive for depression and 245 who had received DSM-IV diagnoses of depression. Acceptability was measured on a 5-point Likert scale of comfort ranging from "Not Comfortable", through "Comfortable" to "Very Comfortable". Results The response rate was just over half for postal surveys (52% and was 100% for telephone and face-to-face surveys (432, 21 and 26 respondents for postal, telephone and face-to-face surveys respectively making 479 respondents in total. Of these, 81.2% indicated that screening with the EPDS had been in the range of "Comfortable" to "Very Comfortable". The other 18.8 % rated screening below the "Comfortable" point, including a small fraction (4.3% who rated answering questions on the EPDS as "Not Comfortable" at the extreme end of the scale. Comfort was inversely related to EPDS score, but the absolute size of this effect was small. Almost all respondents (97% felt that screening was desirable. Conclusion The EPDS had good acceptability in this study for depressed and non-depressed women. Women's views on the desirability of postnatal depression screening appear to be largely independent of personal level of comfort with screening. These results should be useful to policy-makers and are broadly supportive of the Edinburgh Postnatal

Effects of nuclear elastic scattering (NES) on the slowing down of charged fusion products in a typical deuterium plasma and the burn dynamics of ignited Cat-D and DD 3 He plasmas are investigated. A time-dependent multigroup method is used to take into account the effect of finite (non-zero) slowing-down time as well as the discrete nature of NES. It is shown that adequate treatment of the slowing-down process, especially consideration of NES and slowing-down time delay, is essential for an accurate prediction of the dynamic behavior and thermal instability of the plasmas. NES accelerates the temporal plasma behavior and enhances the thermal instability, leading to 20∼30 keV increase in the critical temperature. (author)

Nuclear Export Signal Masking Regulates HIV-1 Rev Trafficking and Viral RNA Nuclear Export.

HIV-1's Rev protein forms a homo-oligomeric adaptor complex linking viral RNAs to the cellular CRM1/Ran-GTP nuclear export machinery through the activity of Rev's prototypical leucine-rich nuclear export signal (NES). In this study, we used a functional fluorescently tagged Rev fusion protein as a platform to study the effects of modulating Rev NES identity, number, position, or strength on Rev subcellular trafficking, viral RNA nuclear export, and infectious virion production. We found that Rev activity was remarkably tolerant of diverse NES sequences, including supraphysiological NES (SNES) peptides that otherwise arrest CRM1 transport complexes at nuclear pores. Rev's ability to tolerate a SNES was both position and multimerization dependent, an observation consistent with a model wherein Rev self-association acts to transiently mask the NES peptide(s), thereby biasing Rev's trafficking into the nucleus. Combined imaging and functional assays also indicated that NES masking underpins Rev's well-known tendency to accumulate at the nucleolus, as well as Rev's capacity to activate optimal levels of late viral gene expression. We propose that Rev multimerization and NES masking regulates Rev's trafficking to and retention within the nucleus even prior to RNA binding. HIV-1 infects more than 34 million people worldwide causing >1 million deaths per year. Infectious virion production is activated by the essential viral Rev protein that mediates nuclear export of intron-bearing late-stage viral mRNAs. Rev's shuttling into and out of the nucleus is regulated by the antagonistic activities of both a peptide-encoded N-terminal nuclear localization signal and C-terminal nuclear export signal (NES). How Rev and related viral proteins balance strong import and export activities in order to achieve optimal levels of viral gene expression is incompletely understood. We provide evidence that multimerization provides a mechanism by which Rev transiently masks its NES peptide

The US Bureau of Labor estimates that there will be an 18% increase in geoscience jobs between 2008 and 2018 in the United States, and demand for geoscientists is expected to rise worldwide as scientists tackle global challenges related to resources, hazards and climate. At the same time, the geoscience workforce is aging, with approximately half of the current workforce reaching retirement age within the next 10-15 years. A new generation of geoscientists must be ready to take the reins. To support this new generation, AGI’s geoscience workforce outreach programs were designed to help retain geoscience students through their degree programs and into careers in the field. These resources include support for early-career professional development and career planning. AGI’s GeoConnection Network for the Geosciences provides a venue for informal dissemination of career information and professional resources. The network links Web 2.0 platforms, including a Facebook page, YouTube Channel and Twitter feed, to build a robust geoscience community of geoscientists at all stages of their careers. Early-career geoscientists can participate in GeoConnection to network with other scientists, and to receive information about professional development and job opportunities. Through GeoConnection packets, students can join professional societies which will assist their transition from school to the workplace. AGI’s member societies provide professional development course work, field trips, career services, interviewing opportunities, and community meetings. As part of the GeoConnection Network, AGI hosts informational webinars to highlight new workforce data, discuss current affairs in the geosciences, and to provide information about geoscience careers. Between December 2009 and August 2010, AGI hosted 10 webinars, with more than 300 total participants for all the webinars, and 5 additional webinars are planned for the remainder of the year.

Borna disease virus (BoDV), which has a negative-sense, single-stranded RNA genome, causes persistent infection in the cell nucleus. The nuclear export signal (NES) of the viral nucleoprotein (N) consisting of leucine at positions 128 and 131 and isoleucine at positions 133 and 136 overlaps with one of two predicted binding sites for the viral phosphoprotein (P). A previous study demonstrated that higher expression of BoDV-P inhibits nuclear export of N; however, the function of N NES in the interaction with P remains unclear. We examined the subcellular localization, viral polymerase activity, and P-binding ability of BoDV-N NES mutants. We also characterized a recombinant BoDV (rBoDV) harboring an NES mutation of N. BoDV-N with four alanine-substitutions in the leucine and isoleucine residues of the NES impaired its cytoplasmic localization and abolished polymerase activity and P-binding ability. Although an alanine-substitution at position 131 markedly enhanced viral polymerase activity as determined by a minigenome assay, rBoDV harboring this mutation showed expression of viral RNAs and proteins relative to that of wild-type rBoDV. Our results demonstrate that BoDV-N NES has a dual function in BoDV replication, i.e., nuclear export of N and an interaction with P, affecting viral polymerase activity in the nucleus.

This study aims to evaluate occurrence, size, composition, and clinical significance of embolized debris during superficial femoral artery atherectomy using all commercially available atherectomy devices. Distal athero/thromboembolic events (DATE) are a universal phenomenon in lower extremity atherectomy procedures (LEAPs) due to the sheer volume of atheroma and the thrombus burden in peripheral arterial disease. Some of these events can be clinically significant. We prospectively gathered clinical and histopathological data on all commercially available atherectomy devices by using embolic protection devices (EPD) in every case. After intervention, the contents of EPD were examined both microscopically and macroscopically. Data from 59 consecutive patients undergoing LEAP were analyzed. DATE occurred 100% of the time. The composition of particulate debris varied with the device used. Grossly visible agglomerated debris was captured by the filter in the majority of patients 54/59 (91.5%). Clinically significant debris, defined by the Preventing Lower Extremity Distal Embolization Using Embolic Filter Protection registry as particle diameter > 0.2 cm, was found in 33/59 (56%) patients. The size of captured debris particles ranged from 0.1 to 2.4 mm. While DATE occurred in all patients, clinically significant DATE occurred in 56% patients undergoing LEAP regardless of the atherectomy device. In spite of a large fraction of the clinically significant debris occurring on our routine dual antiplatelet regimen, no patient suffered an amputation. Although DATE was prevented by the use of EPD in all 59 cases, more data are needed to determine whether the use of EPD translates into a long-term clinical benefit. Use of EPD and optimal thromboprophylaxis should be considered in patients, especially in the setting of compromised distal runoff. PMID:27867291

Official dosimetry with individual electronic dosemeters - the concept in Germany

2005-01-01

Full text: Presently, in Germany passive dosemeters (film batches, RPL, TLD) are used for the official individual monitoring of occupational exposed personal. The application of electronic individual dosemeters (EPD) is carried out mainly for the operative radiation protection control particularly in nuclear power engineering companies, big hospitals und research centres. This means in such institutions double monitoring exists - legally and operatively. A crucial advantage of EPD compared to passive dosemeter is the possibility to adapt the monitoring period to the working time in the control area, e.g. a job related monitoring is available. Germany started a project for an optimized implementation of EPD into the official dosimetry. Objective of the project whose results will be described in the paper is the harmonization of radiation protection of companies workers and outside workers concerning the record of individual and job related exposures. The approval of the EPD by the Federal and Laender authorities as an official dosimetric system demands the implementation of special requirements concerning the data acquisition, data transfer and data evaluation. These issues are focuses of the Federal research project, supervised by the Federal Office for Radiation Protection (BfS) and performed by the Gesellschaft fuer Anlagen- und Reaktorsicherheit (GRS), Cologne to develop a concept in the first stage.

[Early post-partum discharges: benefits, disadvantages and implementation methodology].

Berkane, N

2015-02-01

Early post-partum discharges (EPD) are a hot topic. Already widely practised in many European countries this procedure, was promoted by the government for a decade, requested by representatives of Midwive organisations, desired by some patients, but also criticized by the Academy of Medicine. Well organized and with an obligatory control and follow-up, EPD could help with the management of the shortage of maternity beds and hence increase the satisfaction of the patients. The procedure could even be a way to effectively implement a town-hospital network, something, which has many other benefits. However this procedure is not without potential dangers: lower quality of care, financial risks for the department, and especially a significant increase of the workload of the hospital staff. The main objective of this paper is to detail the benefits and disadvantages of EPD for maternities and to propose an organizational basis if EPD is the procedure of choice. A participatory methodology is essential when using this procedure, due to the important participation of different categories of staff involved in hospital discharge (administrative, medical and paramedical staff) and to exclude complications when certain specifications are not followed or misunderstood.

Several predictors of postpartum mood have been identified in the literature, but the role of maternal expectations in postpartum mental health remains unclear. The aim of this study was to identify whether maternal expectations during the postpartum hospital stay predict adjustment and depressive symptoms at 6 weeks postpartum. The sample included 233 first-time mothers recruited from the postpartum unit of a Midwestern hospital. Participants completed measures of maternal expectations and depressive symptoms (EPDS) at Time 1 (2 d postpartum) and completed EPDS and an Emotional Adjustment Scale (BaM-13) at Time 2 (6 weeks postpartum). A conditional relationship between the expectation that an infant's behavior will reflect maternal skill and Time 2 outcomes (BaM-13 and EPDS) was found, such that endorsing this belief predicted increased depression and poorer adjustment in those with higher (but not lower) Time 1 EPDS scores. Time 2 BaM-13 scores were also negatively predicted by expectations of self-sacrifice and positively predicted by expectations that parenthood would be naturally fulfilling. The expectations that new mothers hold about parenting soon after delivery are predictive of emotional adjustment in the early postpartum period, suggesting a role for discussion of expectations in future preventive strategies.

In this work, the coating of 3-D foam-like glass-ceramic scaffolds with a bioactive mesoporous glass (MBG) was investigated. The starting scaffolds, based on a non-commercial silicate glass, were fabricated by the polymer sponge replica technique followed by sintering; then, electrophoretic deposition (EPD) was applied to deposit a MBG layer on the scaffold struts. EPD was also compared with other techniques (dipping and direct in situ gelation) and it was shown to lead to the most promising results. The scaffold pore structure was maintained after the MBG coating by EPD, as assessed by SEM and micro-CT. In vitro bioactivity of the scaffolds was assessed by immersion in simulated body fluid and subsequent evaluation of hydroxyapatite (HA) formation. The deposition of a MBG coating can be a smart strategy to impart bioactive properties to the scaffold, allowing the formation of nano-structured HA agglomerates within 48 h from immersion, which does not occur on uncoated scaffold surfaces. The mechanical properties of the scaffold do not vary after the EPD (compressive strength ~19 MPa, fracture energy ~1.2 × 10(6) J m(-3)) and suggest the suitability of the prepared highly bioactive constructs as bone tissue engineering implants for load-bearing applications.

Electronic personal dosimeter heralds a revolution in legal dosimetry

The Electronic Personal Dosimeter (EPD) developed by Siemens Plessey Controls and the UK's national Radiological Protection Board is approaching the pre-production stage. It provides ''legal'' dosimetry and all the features of a personal alarming dosimeter. The EPD uses solid state semiconductor detectors for gamma and beta radiation and has a dose threshold of about 1μ Sv, with a low energy gamma range down to 20 KeV. It has a multi function liquid crystal display for instant readout and audible and visual alarms. Two separates dose stores are maintained. Short term dose for tactical management and long term dose for approved dosimetry service record keeping. The latter can be reset only by an approved dosimetry service and is maintained on a search memory disk which can be read even if the EPD is destroyed. (UK)

Full Text Available De nombreuses publications font l'état de l'action négative du cadmium (Cd++ sur la vitellogenèse chez les poissons. Le mécanisme d'action de ce métal n'étant pas clairement établi, une étude a été entreprise afin de déterminer si l'effet du cadmium passait par une action sur l'activité biologique du récepteur des oestrogènes de la truite arc-en-ciel (rtER. Cette étude a été réalisée dans un système de levures recombinantes, exprimant de manière stable rtER, et dans des hépatocytes de truite en culture primaire. Dans la levure, rtER activé par l'oestradiol (E2 contrôle spécifiquement l'expression d'un gène rapporteur codant pour l'enzyme ß-Galactosidase. Une concentration en Cd++ de 10 µM diminue de 45 % l'expression stimulée par l'oestradiol du gène rapporteur dans les levures recombinantes. De même, dans les hépatocytes, l'expression du gène de la vitellogénine (VTG, gène sous le contrôle positif de E2, est diminuée de 65 %. Le cadmium n'affecte pas la liaison de E2 à son récepteur et seule l'activité hormonodépendante est affectée par ce métal. Les résultats de cette étude montrent que l'effet négatif du cadmium sur l'action de l'oestradiol passe vraisemblablement par une action directe de ce métal sur la fonction de transactivation hormono-dépendante de rtER.

Popular Literature Discourses in Athenian Suburbia: The Northern Suburbs Les banlieues nord d’Athènes dans les discours littéraires populaires

Full Text Available Suburbia, home to a life-style many people aspire to, could be seen as a marriage between urban and countryside life, and, as such, it should be seen as a vital arena for interdisciplinary research on the urban-rural paradigm. This paper explores the ways whereby discourses on what is stereotypically seen as posh northern Athens suburban culture (Voreia Proastia are represented in popular literature. The main argument is that Voreia Proastia suburban culture could be seen as positioned on an urban/countryside continuum. This is grounded on the simple reason that, both at the speech level and in terms of lifestyle, it encompasses features of urban and rural worlds, the former associated with the “new-poor” or “elegant poverty” people, the latter with the “new-rich”.Les zones périurbaines donnent lieu à un train de vie auquel aspirent de nombreuses personnes, étant donné qu’elles semblent marier la vie urbaine et la vie rurale. De ce fait, ces zones constituent un domaine essentiel pour la recherche interdisciplinaire sur le paradigme urbain-rural. Cet article cherche à examiner les manières selon lesquelles les discours associés aux banlieues nord d’Athènes (Voreia Proastia, considérées de manière stéréotypée comme chics, sont repris par la littérature populaire. A travers l’analyse de cette appropriation, nous tentons de comprendre leur signification sociale. L’argument principal avancé ici est que la culture suburbaine de Voreia Proastia se positionne sur un continuum entre l’urbain et le rural pour la simple raison qu’au niveau des pratiques langagières et des styles de vie, elle englobe à la fois des caractéristiques du monde urbain, associé aux « nouveaux pauvres » ou à la « pauvreté élégante », et du monde rural, associé aux « nouveaux riches ».

" Blaming, shaming, humiliation": Stigmatising medical interactions among people with non-epileptic seizures.

Robson, Catherine; Lian, Olaug S

2017-01-01

Background : People with non-epileptic seizures (NES) describe challenging relationships with health professionals, and explain negative interactions as common and expected. Despite these difficulties, little is known about how people with NES experience difficult healthcare encounters. Methods : Using a thematic discourse analysis approach, we analysed the free-text survey responses of 135 people with NES and asked: what kind of challenges do people living with this condition encounter when interacting with health professionals, and how do they experience the consequences of difficult interactions? We explore their experiences by interpreting the latent meaning of participants' texts from a social-constructionist perspective on health and illness. Results : The overarching narrative depicts a fundamental breakdown in patient-provider relationships. According to our data, the negative experiences of study participants emerge from more than practitioners' lack of awareness of NES and access to information about the condition - to the extent that it is available. In examining the challenges people with NES encounter when interacting with health professionals, their main experiences centre on blame and humiliation. When exploring their experiences, theories of stigma serve as a useful theoretical framework. Conclusions : Normative judgements arising from psychogenic understandings of NES are stigmatising and restrict professional displays of respectful (patient-centred) care. Those with the condition depict being negatively stereotyped, illegitimated and held morally culpable by health professionals. Perceived to lack medical, moral and credible status, participants describe practitioners who treat them with disrespect, and some recount conduct that defies all ethical and professional obligations and standards. These encounters can have wide-ranging adverse consequences for patients: emotionally, physically, and for their future healthcare. The quality of healthcare

This study aims to determine the lowest effective of three Nestorone (NES)/estradiol (E2) transdermal gel doses to ensure ovulation suppression in 90-95% of cycles. This was a randomized, open-label, three-treatment-period cross-over study to evaluate the effects of NES/E2 transdermal gel on ovulation inhibition, suppression of follicular growth and pharmacokinetic parameters. The doses were low (1.5 mg NES/0.5 mg E2), medium (3.0 mg NES/1.0 mg E2) and high (4.5 mg NES/1.5 mg E2). Participants applied gel daily to a fixed area on the abdomen for 21 consecutive days. They were interviewed regarding their experiences using the gel. Eighteen participants were randomized; 16 completed the study. Median NES C(max) values for low, medium and high dose groups at day 21 were 318.6 pmol/L, 783.0 pmol/L and 1063.8 pmol/L, respectively. Median maximum follicular diameter was higher with the lowest dose with 16.2 mm versus 10.0 and 10.4 mm with the medium and high doses, respectively. Among adherent participants, ovulation was inhibited in all dose groups, except for one participant in the medium dose (6.7%) that had luteal activity and an ultrasound image suggestive of a luteinized unruptured follicle. There were few reports of unscheduled bleeding, with more episodes reported for the lower dose. Adverse events were mild, and no skin irritation was reported from gel application. While all three doses blocked ovulation effectively and were evaluated as safe and acceptable, the medium dose was considered the lowest effective dose based on a more adequate suppression of follicular development. Further development of this novel contraceptive delivering NES and E2 is warranted and has potential for improved safety compared to ethinyl-estradiol-based methods. Copyright © 2015 Elsevier Inc.

Conservation priorities in a biodiversity hotspot: analysis of narrow endemic plant species in New Caledonia.

Directory of Open Access Journals (Sweden)

Adrien S Wulff

Full Text Available New Caledonia is a global biodiversity hotspot facing extreme environmental degradation. Given the urgent need for conservation prioritisation, we have made a first-pass quantitative assessment of the distribution of Narrow Endemic Species (NES in the flora to identify species and sites that are potentially important for conservation action. We assessed the distributional status of all angiosperm and gymnosperm species using data from taxonomic descriptions and herbarium samples. We characterised species as being NES if they occurred in 3 or fewer locations. In total, 635 of the 2930 assessed species were classed as NES, of which only 150 have been subjected to the IUCN conservation assessment. As the distributional patterns of un-assessed species from one or two locations correspond well with assessed species which have been classified as Critically Endangered or Endangered respectively, we suggest that our distributional data can be used to prioritise species for IUCN assessment. We also used the distributional data to produce a map of "Hotspots of Plant Narrow Endemism" (HPNE. Combined, we used these data to evaluate the coincidence of NES with mining activities (a major source of threat on New Caledonia and also areas of conservation protection. This is to identify species and locations in most urgent need of further conservation assessment and subsequent action. Finally, we grouped the NES based on the environments they occurred in and modelled the habitat distribution of these groups with a Maximum Entropy Species Distribution Model (MaxEnt. The NES were separable into three different groups based primarily on geological differences. The distribution of the habitat types for each group coincide partially with the HPNE described above and also indicates some areas which have high habitat suitability but few recorded NES. Some of these areas may represent under-sampled hotspots of narrow endemism and are priorities for further field work.

Analysis of the nuclear localization signal of TRF1 in non-small cell lung cancer

Full Text Available Several studies revealed a similar down-regulation of telomeric repeat binding factor 1 (TRF1 in tumors. We have previously reported the TRFl expression levels were down-regulation in non-small cell lung cancer (NSCLC. The regulation of TRFl localization is proposed to be important for the function and expression. The nuclear localization signal (NLS and nuclear export signal (NES are often important clues to localization of protein. The objective of the present study was to investigate the NLS and NES of TRFl in NSCLC patients. Thirty (30 patients with NSCLCs had undergone radical operations in The First Affiliated Hospital, College of Medicine, Zhejiang University. DNA sequences of NLSs and NESs were amplified by PCR. The PCR products were analyzed by DNA sequencing. There were four NLSs of the TRFl protein, including two monopartite and two bipartite NLSs. The NLSs sequences were included in 337KKERRVGTPQSTKKKKESRR356. The exon 8 and exon 9 of TRFl DNA were covered the NLS sequences. The sequences of predicted NESs were 11WMLDFLCLSL86 and 174NLLKLQALAV183, respectively. The exon 1, exon 3 and exon 4 of TRFl were covered the NES sequences. In NSCLCs, there was no a mutation, deletion, or substitution in NLS and NES of TRFl. We conclude that the NLS and NES sequences in NSCLCs patients did not have mutations. Down-expression of TRFl does not indicate gene mutation of NLS and NES in NSCLCs.

In this study, a nanoemulsion (NE) system was investigated for intravenous delivery of lipophilic and venous irritant drugs. NEs were prepared to deliver diallyl trisulfide (DT) for systemic therapy of bacterial and fungal infection, egg phospholipid was chosen as the main emulsifier, and two co-emulsifiers were also incorporated, including Poloxamer 188 (P188) and Solutol HS 15 (S15). Soybean oil was used as the dispersed phases, forming stable DT NEs with small particle sizes. The venous irritation of DT NEs was evaluated by in vitro human umbilical cord endothelial cells (CRL 1730) compatibility model with the intracellular adenosine triphosphate (ATP) and guanosine triphosphate (GTP) concentrations as the indices. The intracellular ATP and GTP reduction changed with the incorporation of a variety of co-emulsifiers, which varied in a free DT concentration-dependent manner. It was deduced that the free DT concentrations of NEs containing co-emulsifiers were determined by the partition coefficient of DT between oil and surfactant buffer solution. In conclusion, NE was an appropriate delivery system for lipophilic and venous irritant drug, and optimization of the composition of emulsifiers was an effective method to alleviate the venous irritation of DT NEs.

Highlights: • Obtaining nano-crystalline magnesium titanium oxide powders by solar physical vapor deposition (SPVD) process. And using these nano-powders to obtain thick films on conducting substrates by electrophoretic deposition (EPD). • SPVD is a core innovative, original and environmentally friendly process to prepare nano-materials in a powder form. • Sintered thick films exhibited dielectric constant, ε{sub r} ∼18.3 and dielectric loss, tan δ ∼0.0012 at 1 MHz, which is comparable to the values reported earlier. • New contributions to the pool of information on the preparation of nano-structured MgTiO{sub 3} thick films at low temperatures. • A considerable decrease in synthesis temperature of pure MgTiO{sub 3} thick film was observed by the combination of SPVD and EPD. - Abstract: A novel combination of solar physical vapor deposition (SPVD) and electrophoretic deposition (EPD) that was developed to grow MgTiO{sub 3} nanostructured thick films is presented. Obtaining nanostructured MgTiO{sub 3} thick films, which can replace bulk ceramic components, a major trend in electronic industry, is the main objective of this work. The advantage of SPVD is direct synthesis of nanopowders, while EPD is simple, fast and inexpensive technique for preparing thick films. SPVD technique was developed at CNRS-PROMES Laboratory, Odeillo-Font Romeu, France, while the EPD was performed at University of Aveiro – DeMAC/CICECO, Portugal. The nanopowders with an average crystallite size of about 30 nm prepared by SPVD were dispersed in 50 ml of acetone in basic media with addition of triethanolamine. The obtained well-dispersed and stable suspensions were used for carrying out EPD on 25 μm thick platinum foils. After deposition, films with thickness of about 22–25 μm were sintered in air for 15 min at 800, 900 and 1000 °C. The structural and microstructural characterization of the sintered thick films was carried out using XRD and SEM, respectively. The

Full Text Available Postnatal maternal depression (PND is a significant risk factor for infant mental health. Although often targeted alongside other factors in perinatal home-visiting programs with vulnerable families, little impact on PND has been observed.This study evaluates the impact on PND symptomatology of a multifocal perinatal home-visiting intervention using psychologists in a sample of women presenting risk factors associated with infant mental health difficulties.440 primiparous women were recruited at their seventh month of pregnancy. All were future first-time mothers, under 26, with at least one of three additional psychosocial risk factors: low educational level, low income, or planning to raise the child without the father. The intervention consisted of intensive multifocal home visits through to the child's second birthday. The control group received care as usual. PND symptomatology was assessed at baseline and three months after birth using the Edinburgh Postnatal Depression Scale (EPDS.At three months postpartum, mean (SD EPDS scores were 9.4 (5.4 for the control group and 8.6 (5.4 for the intervention group (p = 0.18. The difference between the mean EPDS scores was 0.85 (95% CI: 0.35; 1.34. The intervention group had significantly lower EPDS scores than controls in certain subgroups: women with few depressive symptoms at inclusion (EPDS <8: difference = 1.66 (95%CI: 0.17; 3.15, p = 0.05, adjusted for baseline EPDS score, women who were planning to raise the child with the child's father: difference = 1.45 (95%CI: 0.27; 2.62, p = 0.04 (adjusted; women with a higher educational level: difference = 1.59 (95%CI: 0.50; 2.68 p = 0.05 (adjusted.CAPEDP failed to demonstrate an overall impact on PND. However, post-hoc analysis reveals the intervention was effective in terms of primary prevention and in subgroups of women without certain risk factors.

Although a number of studies have examined the factor structure of the Edinburgh Postnatal Depression Scale (EPDS) in predominately White or African American samples, no published research has reported on the factor structure among Hispanic women who reside in the United States. The current study examined the factor structure of the EPDS among Hispanic mothers in the United States. Among 220 Hispanic women, drawn from a pediatric primary care setting, with an infant aged 0 to 10 months, 6 structural models guided by the empirical literature were evaluated using confirmatory factor analysis. Results supported a 2-factor model of depression and anxiety as the best fitting model. Multigroup models supported the factorial invariance across women who completed the EDPS in English and Spanish. These findings provide initial support for the 2-factor structure of the EPDS among Hispanic women in the United States. © 2014 Wiley Periodicals, Inc.

The electrophoretic deposition (EPD) is recognized as the most versatile technique for processing particulate materials, due to low cost, deposition in minutes and forming of pieces with complex geometry shapes. In this work an experimental setup for the simultaneous conformation of 16 ceramic tubes by EPD was built. Bimodal submicron Yttria-stabilized zirconia particles were deposited into graphite electrodes, after suitably adjusting the rheological characteristics of the suspension in isopropanol. After graphite burning and YSZ sintering at 1500 deg C, the ceramic tubes were characterized by X-ray diffraction, scanning probe microscope, impedance spectroscopy and electrical response as a function of oxygen content. Small dense one end-closed ceramic tubes, fully stabilized in the cubic phase, were successfully obtained by the EPD technique, showing the ability of that technique for processing large quantities of tubular solid electrolytes with electrical response to different amounts of oxygen according to the Nernst law (author)

We have developed two types of new small, light, electronic personal dosemeters (EPDs) which can be used for dose management of workers at nuclear power plants without additional dosemeters. The one is a card size dosemeter to measure gamma exposure dose and the other is a multi sensor dosemeter to measure gamma, beta and neutron dose respectively. With direct reading, alarm and instant readout, these EPDs have ruggedness and if failure happens, memory readout facility can read dose data in the dosemeter. These dosemeters have enough performance characteristics and reliability for use as a dose record dosemeter. The gamma dosemeter has a lightweight credit card size body to reduce workers' burden of wearing it. The multi sensor dosemeter has four hetero junction silicon detectors that detect gamma, beta, thermal and fast neutron respectively and it is smaller and lighter than conventional alarm dosemeters presently used at nuclear power plant. Thermal neutron detector has thin Boron layer deposited on silicon surface and fast neutron detector has polyethylene radiator in front of silicon wafer. These dosemeters with a rechargeable battery can operate more than 15 hours continuously. The data transmission can be made with radiofrequency wave in area smaller than 30 cm distance between dosemeter and readout system. These dosemeters were introduced into Tokai nuclear power plant on October 1997, Tsuruga nuclear power plant on December 1997 of Japan Atomic Power Company and have been operating satisfactorily. At now these EPD have been used as secondary dosemeters. The performance characteristics comparison between EPD and film badge(FB) have been continuing to assure EPD suitable for use as a primary dosemeter. Near future Japco will abolish FB and establish the radiation control system based on the electronic personal dosemeters as a dose record dosemeter. (author)

Heterogeneity of postpartum depression: a latent class analysis

Science.gov (United States)

2016-01-01

Summary Background Maternal depression in the postpartum period confers substantial morbidity and mortality, but the definition of postpartum depression remains controversial. We investigated the heterogeneity of symptoms with the aim of identifying clinical subtypes of postpartum depression. Methods Data were aggregated from the international perinatal psychiatry consortium Postpartum Depression: Action Towards Causes and Treatment, which represents 19 institutions in seven countries. 17 912 unique subject records with phenotypic data were submitted. We applied latent class analyses in a two-tiered approach to assess the validity of empirically defined subtypes of postpartum depression. Tier one assessed heterogeneity in women with complete data on the Edinburgh postnatal depression scale (EPDS) and tier two in those with postpartum depression case status. Findings 6556 individuals were assessed in tier one and 4245 in tier two. A final model with three latent classes was optimum for both tiers. The most striking characteristics associated with postpartum depression were severity, timing of onset, comorbid anxiety, and suicidal ideation. Women in class 1 had the least severe symptoms (mean EPDS score 10·5), followed by those in class 2 (mean EPDS score 14·8) and those in class 3 (mean EPDS score 20·1). The most severe symptoms of postpartum depression were significantly associated with poor mood (mean EPDS score 20·1), increased anxiety, onset of symptoms during pregnancy, obstetric complications, and suicidal ideation. In class 2, most women (62%) reported symptom onset within 4 weeks postpartum and had more pregnancy complications than in other two classes (69% vs 67% in class 1 and 29% in class 3). Interpretation PPD seems to have several distinct phenotypes. Further assessment of PPD heterogeneity to identify more precise phenotypes will be important for future biological and genetic investigations.

Night eating syndrome (NES) is characterized by evening hyperphagia and/or nocturnal ingestion. The main objective of this study was to assess the percentage of students complying with symptoms and behaviors consistent with the diagnostic criteria for NES, and explore its association with body mass index (BMI), dietary habits, physical activity, smoking status, and sleep patterns, among a sample of college students. A cross-sectional survey was conducted among a sample of 413 undergraduate students, mean age of 20.6 ± 1.68 SD, at Central Michigan University. Students completed an online survey including demographic information and the Night Eating Diagnostic Questionnaire (NEDQ) and Pittsburgh Sleep Quality Index Questionnaire (PSQI). Participants were grouped based on self-reporting of the presence and frequency of night eating-related symptoms and behaviors related to the diagnostic criteria for NES as follows: normal, mild night eater, moderate night eater, and full-syndrome night eater. Pearson's Chi-squared, Student's t test, and Wilcoxon rank-sum test were used to test the association between students with and without any night eating behavior in relation to BMI, lifestyle variables, and sleep duration/quality. Results showed that the proportion of students complying with symptoms and behaviors consistent with full-syndrome of NES was 1.2%. There were no significant differences between students complying with symptoms and behaviors consistent with any level of NES and those without any night eating behavior regarding BMI, eating habits, physical activity, and smoking status. NES was significantly related to sleep duration (P = 0.023). Students complying with symptoms consistent with any level of NES reported shorter sleep time and had higher total PSQI score (6.73 ± 4.06) than students without the syndrome (5.61 ± 2.61) (P = 0.007). Although the percentage of students complying with full-syndrome NES was relatively low in our student sample

Stability of Mixed-Strategy-Based Iterative Logit Quantal Response Dynamics in Game Theory

Zhuang, Qian; Di, Zengru; Wu, Jinshan

2014-01-01

Using the Logit quantal response form as the response function in each step, the original definition of static quantal response equilibrium (QRE) is extended into an iterative evolution process. QREs remain as the fixed points of the dynamic process. However, depending on whether such fixed points are the long-term solutions of the dynamic process, they can be classified into stable (SQREs) and unstable (USQREs) equilibriums. This extension resembles the extension from static Nash equilibriums (NEs) to evolutionary stable solutions in the framework of evolutionary game theory. The relation between SQREs and other solution concepts of games, including NEs and QREs, is discussed. Using experimental data from other published papers, we perform a preliminary comparison between SQREs, NEs, QREs and the observed behavioral outcomes of those experiments. For certain games, we determine that SQREs have better predictive power than QREs and NEs. PMID:25157502

2002-04-01

Full Text Available Abstract Background This survey's objective was to provide planning information by examining utilization patterns, health outcomes and costs associated with existing practices in the management of postpartum women and their infants. In particular, this paper looks at a subgroup of women who score ≥ 12 on the Edinburgh Postnatal Depression Survey (EPDS. Methods The design is cross-sectional with follow-up at four weeks after postpartum hospital discharge. Five Ontario hospitals, chosen for their varied size, practice characteristics, and geographic location, provided the setting for the study. The subjects were 875 women who had uncomplicated vaginal deliveries of live singleton infants. The main outcome measures were the EPDS, the Duke UNC Functional Social Support Questionnaire and the Health and Social Services Utilization Questionnaire. Results EPDS scores of ≥ 12 were found in 4.3 to 15.2% of otherwise healthy women. None of these women were being treated for postpartum depression. Best predictors of an EPDS score of ≥ 12 were lack: of confident support, lack of affective support, household income of Conclusions Primary care physicians, midwives, and public health nurses need to screen for depression at every opportunity early in the postpartum period. A mother's expression of undue concern about her own or her baby's health may be predictive of postpartum depression. Flexible, mother-focused support from community providers may decrease the prevalence of postpartum depression.

Cataphoretic assembly of cationic dyes and deposition of carbon nanotube and graphene films.

Su, Y; Zhitomirsky, I

2013-06-01

Cathodic electrophoretic deposition (EPD) method has been developed for the fabrication of thin films from aqueous solutions of crystal violet (CV) dyes. The films contained rod-like particles with a long axis oriented perpendicular to the substrate surface. The proposed deposition mechanism involved cataphoresis of cationic CV(+) species, base generation in the cathodic reactions, and charge neutralization at the electrode surface. The assembly of rod-like particles was governed by π-π interactions of polyaromatic CV molecules. The deposition kinetics was studied by quartz crystal microbalance. CV dyes allowed efficient dispersion of multiwalled carbon nanotubes (MWCNTs) and graphene in water at relatively low CV concentrations. The feasibility of cathodic EPD of MWCNT and graphene from aqueous suspensions, containing CV, has been demonstrated. The deposition yield was investigated at different CV concentrations and deposition voltages. The relatively high deposition yield of MWCNT and graphene indicated that CV is an efficient dispersing, charging, and film forming agent for EPD. Electron microscopy data showed that at low CV concentrations in MWCNT or graphene suspensions and low deposition voltages, the films contained mainly MWCNT or graphene. The increase in the CV concentration and/or deposition voltage resulted in enhanced co-deposition of CV. The EPD method developed in this investigation paves the way for the fabrication of advanced nanocomposites by cathodic electrodeposition. Copyright © 2013 Elsevier Inc. All rights reserved.

Highlights: {center_dot} HA/TiO{sub 2} coating were prepared by a MAO and EPD technique. {center_dot} The NaOH electrolyte solution containing HA particles is employed. {center_dot} MAO and EPD treatment enhances the corrosion resistance and bioactivity of titanium. - Abstract: In situ composite coating of hydroxyapatite (HA)/TiO{sub 2} were produced on titanium (Ti) substrate by micro-arc oxidation coupled with electrophoretic deposition (MAO and EPD) technique with different concentrations of HA particles in the 0.2 M NaOH electrolyte solution. The surface morphology and chemical composition of the hybrid coating were effected by HA concentration. The amount of HA particles incorporated into coating layer increased with increasing HA concentration used in the electrolyte solution. The corrosion behavior of the coating layer in simulated body fluids (SBF) was evaluated using a potentiodynamic polarization test. The corrosion resistance of the coated sample was increased compared to the untreated Ti sample. The in vitro bioactivity assessment showed that the MAO and EPD treated Ti substrate possessed higher apatite-forming ability than the untreated Ti. Moreover, the apatite-forming ability had a positive correlation with HA concentration. In addition, the cell behavior was also examined using cell proliferation assay and alkaline phosphatase ability. The coating formed at HA concentration of 5 g/L exhibited the highest cell ability.

The Night Eating Syndrome (NES) is a disorder characterized by the clinical features of morning anorexia, evening hyperphagia, and insomnia with awakenings followed by nocturnal food ingestion. The core clinical feature appears to be a delay in the circadian timing of food intake. The diagnosis and early treatment of NES may represent an important means of prevention for obesity. Aims. The aim of the present study was to determine the vulnerability to develop NES between a clinical sample of patients with psychiatric disorders and a non clinical sample. We investigated a possible relation between stress and a dysfunctional eating behaviors as NES. Methods. The Night Eating Questionnaire (NEQ) has been administered to 147 psychiatric outpatients and to 531 subjects attending the University of L'Aquila. The NEQ is a questionnaire used to evaluate the prevalence of NES. The sample has been also evaluated through the Stress-related Vulnerability Scale (SVS) to measure both perceived stress and social support. Results. The 8.2% of patients scored above the diagnostic cut-off of the NEQ, compared to the 2.1% in the sample of healthy subjects. The majority of patients who had shown NEQ>25 had a diagnosis of major depressive disorder (MDD). The total scores on the NEQ were strongly associated with the SVS total score and especially with the "lack of social support" subscale. Conclusions. This study shows the increased vulnerability of NES in the sample of psychiatric patients compared to the sample of healthy subjects. The study further confirms the strong association between perceived stress, social support, altered eating behaviors and obesity.

Full Text Available Un échantillonnage systématique des principaux affleurements des séries carbonatées néogènes de Sainte Croix (Iles Vierges a permis de préciser leur extension stratigraphique. C'est ainsi que la section-type de la formation Kingshill, qui avait été récemment attribuée au Miocène supérieur, est désormais datée du Miocène moyen d'après son riche contenu faunistique en foraminifères planctoniques et nannofossiles calcaires. Les diverses mesures pétrophysiques effectuées dans des niveaux d'environnement de dépôts différents (plate-forme, pente, bassin tendent à prouver que de bonnes porosités et perméabilités, donc de bons réservoirs, pourraient être trouvées dans des séries de pentes ou de fond de bassins associés à des plates-formes carbonatées. Systematic sampling of the main outcrops of Neogene carbonate series on Saint Croix, Virgin Islands, has enabled their stratigraphic extension to be determined. In this way, the Kingshill formation type section, which has recently been attributed to the late Miocene, is henceforth dated from the middle Miocene according to planktonic foraminifers and calcareous nannofossils. The different petrophysical measurements made in strata originated from different depositional environments (shelf, slope, basin tend to prove that good porosities and permeabilities, hence good reservoirs, might be found in slope or basin-bottom series associated with carbonate banks.

2018-01-04

NLSdb is a database collecting nuclear export signals (NES) and nuclear localization signals (NLS) along with experimentally annotated nuclear and non-nuclear proteins. NES and NLS are short sequence motifs related to protein transport out of and into the nucleus. The updated NLSdb now contains 2253 NLS and introduces 398 NES. The potential sets of novel NES and NLS have been generated by a simple 'in silico mutagenesis' protocol. We started with motifs annotated by experiments. In step 1, we increased specificity such that no known non-nuclear protein matched the refined motif. In step 2, we increased the sensitivity trying to match several different families with a motif. We then iterated over steps 1 and 2. The final set of 2253 NLS motifs matched 35% of 8421 experimentally verified nuclear proteins (up from 21% for the previous version) and none of 18 278 non-nuclear proteins. We updated the web interface providing multiple options to search protein sequences for NES and NLS motifs, and to evaluate your own signal sequences.

2016-04-21

The importance of natural environments (NEs) for physical activity (PA) has been studied extensively. However, there is scant evidence to explain the motivational processes underlying the NE-PA relation. The aim of this study was to investigate the NE-PA relation using an ecological framework, focusing on perception of NEs, childhood experiences and possible intra- and inter-individual mediators. Data were retrieved from a cross-sectional survey among 2168 adults from all over Norway. In addition, the coverage of NEs by municipalities was retrieved from national registers. Logistic regression showed that, unlike the self-reported proximity to NEs, higher ratings of perceived supportiveness of NEs for PA predicted participation in NE-based PA for at least 60 min/week or 150 min/week, before and after controlling for socio-demographic characteristics. Reporting frequent experiences in nature during childhood was also an important predictor of higher levels of NE-based PA. Furthermore, a mediational analysis showed that the effect of both predictors was mediated by "feelings about nature" and "social networks". These findings indicate that to encourage the use of local NE for PA, not only should environmental perceptions be taken into account, positive feelings towards nature alongside opportunities to share activity in nature with others should also be promoted.

Morbilliviruses, which belong to the Mononegavirales, replicate its RNA genome in the cytoplasm of the host cell. However, they also form characteristic intranuclear inclusion bodies, consisting of nucleoprotein (N), in infected cells. To analyze the mechanisms of nucleocytoplasmic transport of N protein, we characterized the nuclear localization (NLS) and nuclear export (NES) signals of canine distemper virus (CDV) N protein by deletion mutation and alanine substitution of the protein. The NLS has a novel leucine/isoleucine-rich motif (TGILISIL) at positions 70-77, whereas the NES is composed of a leucine-rich motif (LLRSLTLF) at positions 4-11. The NLS and NES of the N proteins of other morbilliviruses, that is, measles virus (MV) and rinderpest virus (RPV), were also analyzed. The NLS of CDV-N protein is conserved at the same position in MV-N protein, whereas the NES of MV-N protein is located in the C-terminal region. The NES of RPV-N protein is also located at the same position as CDV-N protein, whereas the NLS motif is present not only at the same locus as CDV-N protein but also at other sites. Interestingly, the nuclear export of all these N proteins appears to proceed via a CRM1-independent pathway

We sought to determine the type of personality disorder cluster associated with patients with nonepileptic psychogenic seizures (NES) compared with that of patients with epileptic seizures (ES). Consecutive adult patients admitted for video/EEG monitoring found to have NES were compared with a simultaneously admitted patient with confirmed epilepsy. Personality was assessed using the Structured Clinical Interview for DSM-IV-TR Axis II Personality Disorders. Personality disorders were then divided into personality clusters described in the DSM-IV-TR: A = paranoid, schizotypal, schizoid; B = borderline, histrionic, antisocial, narcissistic; or C = avoidant, dependent, obsessive-compulsive. Thirteen of 16 patients with NES and 12 of 16 patients with ES met criteria for personality disorders. Patients with NES were more likely to meet criteria for a personality disorder in Cluster A or B, compared with patients with ES, who were more likely to have Cluster C personality disorders (chi(2) test, P=0.007). We propose that the personality traits of patients with NES contribute to the development of nonepileptic psychogenic seizures. However, the large proportion of patients with ES with Cluster C personality disorders was unexpected, and further, for the patients with epilepsy, the direction of the association of their personality traits with the development of epilepsy is unknown.

Full Text Available Laura A Berner,1 Kelly C Allison2 1Department of Psychology, Drexel University, 2Department of Psychiatry, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA, USA Abstract: Night eating syndrome (NES is a form of disordered eating associated with evening hyperphagia (overeating at night and nocturnal ingestions (waking at night to eat. As with other forms of disordered eating, cognitive and behavioral treatment modalities may be effective in reducing NES symptoms. This review presents evidence for a variety of behavioral treatment approaches, including behavioral therapy, phototherapy, behavioral weight loss treatment, and cognitive-behavioral therapy. A more detailed overview of cognitive-behavioral therapy for NES is provided. All of these studies have been case studies or included small samples, and all but one have been uncontrolled, but the outcomes of many of these approaches are promising. Larger randomized controlled trials are warranted to advance NES treatment literature. With the inclusion of NES in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5 as a “Feeding or Eating Disorder Not Elsewhere Classified,” more sophisticated, empirically-supported, behaviorally-based treatment approaches are much needed.

1995-12-31

The Hong Kong Environmental Protection Department (EPD) is currently operating an air quality monitoring network in the territory. There are nine monitoring stations, each with air quality monitoring equipment, meteorological instruments and a data logger. Five minute averaged data are transmitted through telephone lines to the central computer at the EPD Air Laboratory and are also stored in the data logger on site, as backup. At present, the EPD releases its air quality measurements to the public via monthly and special press releases, and annual reports.

Full Text Available This study investigated the electrophoretic deposition (EPD of the natural polymer zein combined with bioactive glass (BG particles. Through the deposition of various BG compositions, namely 45S5 BG and Cu-doped BG, this work sought to demonstrate the ability of the films to potentiate the formation of hydroxyapatite (HA in contact with simulated body fluid (SBF. Following incubation in SBF, the physical and chemical surface properties of the EPD films were evaluated using different characterization techniques. The formation of HA at the surface of the coatings following immersion in SBF was confirmed using Fourier transform infrared spectroscopy (FTIR. The results demonstrated HA formation in all coatings after seven days of immersion in SBF. Coating morphology and degradation of the zein films were characterized using environmental scanning electron microscopy (ESEM. The results confirmed EPD as a very convenient room temperature technique for production of ion releasing, bioactive, and antibacterial coatings for potential application in orthopedics.

The Hong Kong Environmental Protection Department (EPD) is currently operating an air quality monitoring network in the territory. There are nine monitoring stations, each with air quality monitoring equipment, meteorological instruments and a data logger. Five minute averaged data are transmitted through telephone lines to the central computer at the EPD Air Laboratory and are also stored in the data logger on site, as backup. At present, the EPD releases its air quality measurements to the public via monthly and special press releases, and annual reports. However, as public awareness of air pollution problems has increased, there has been an urgent need for timely and simpler information about air pollution levels. The development and operation of an Air Pollution Index (API) system has addressed that need. This presentation discusses the API computation, the information and advice released to the general public and how they can access the API information. Some API results are also presented. (author)

In this study, the nano-Co_3O_4 films (NCOFs) have been prepared by a one-step cathodic electrophoretic deposition (C-EPD) in aqueous solutions with micro-additive polyethylenimine at ambient temperature and pressure for oxide film-based supercapacitors. The phase composition and morphology of the NCOFs were studied by X-ray diffraction (XRD) and focused ion beam scanning electron microscope (FIB-SEM), respectively. In addition, the deposition kinetics of nano-Co_3O_4 particles using C-EPD process were investigated in detail. The electrochemical capacitance behaviors of the NCOFs electrode were analyzed by cyclic voltammetry, galvanostatic charge–discharge studies, and electrochemical impedance spectroscopy in 2 M KOH solution. The electrochemical experiments revealed that the highest capacitance of 233.6 F g"−"1 at 0.5 A g"−"1, 93.5 % of which still be maintained after 2000 charge–discharge cycles. These findings suggested the potential application of the NCOFs prepared by C-EPD in the electrochemical supercapacitors.

INPRO provides for: • Development of global and regional nuclear energy evolution scenarios and visions to inform national policy development and collaboration among Member States; • Improved understanding of practical steps in transitions to regionally and globally sustainable NESs; • Improved understanding of innovations in technical and institutional features of NES that support transition to sustainable NES; • Holistic assessment of proposed and planned NES to assure that the stated objective of sustainability is rigorously measureable using a defensible consensus approach; and • Communication of insights gained through INPRO activities, and other subjects of direct shared interest to sustainable nuclear energy development, to all involved and interested stakeholders through the INPRO Dialogue Forum. All INPRO activities combined seek to develop a structured holistic approach to assessment and dynamic analysis of NES sustainability. This, together with consideration of both innovative technology and institutional arrangements, may potentially lead to improved understanding of the approach to globally sustainable nuclear energy systems

We previously found that androgen receptor (AR) activity mediates two effects of T in adult male mice: reduction of anxiety-like behaviors and dampening of the hypothalamic-pituitary-adrenal response to stress. To determine whether brain ARs mediate these effects, we used the Cre/loxP technology seeking to disable AR throughout the central nervous system (CNS). Female mice carrying the floxed AR allele (ARlox) were crossed with males carrying cre recombinase transgene controlled by the nestin promoter (NesCre), producing cre in developing neurons and glia. Among male offspring, four genotypes resulted: males carrying ARlox and NesCre (NesARko), and three control groups (wild types, NesCre, and ARlox). Reporter mice indicated ubiquitous Cre expression throughout the CNS. Nevertheless, AR immunocytochemistry in NesARko mice revealed efficient knockout (KO) of AR in some brain regions (hippocampus and medial prefrontal cortex [mPFC]), but not others. Substantial AR protein was seen in the amygdala and hypothalamus among other regions, whereas negligible AR remained in others like the bed nucleus of the stria terminalis and dorsal periaqueductal gray. This selective KO allowed for testing the role of AR in hippocampus and mPFC. Males were castrated and implanted with T at postnatal day 60 before testing on postnatal day 90-100. In contrast with males with global KO of AR, T still modulated anxiety-related behavior and hypothalamic-pituitary-adrenal activity in NesARko males. These results leave open the possibility that AR acting in the CNS mediates these effects of T, but demonstrate that AR is not required in the hippocampus or mPFC for T's anxiolytic effects.
