    AS the Digital Video fad sweeps China, the in-phrase on the Internet, in fashion magazines, on campus, and amongst the young generation is "did you DV today?" The word DV has transcended its original meaning to become a kind of lifestyle. When Starbucks and Italo Calvino first entered China, they were regarded as ultimate status symbols, until they became ubiquitous. This is the case with DV: as

    Full Text Available Pervasive advertising and marketing efforts promote consumer market digital video (DV format camcorders as the ideal acquisition technology for Internet video production. A shared digital nature and simple interconnections between cameras and computers using IEEE1394/FireWire/i.Link® format digital cabling do suggest a natural affinity between DV and Internet production. However, experience with Web delivery reveals numerous obstacles associated with consumer-friendly camcorder design and feature sets that can severely compromise Internet streaming video quality. This paper describes the various features in consumer and industrial grade DV camcorder designs that lead to unnecessary image quality loss, and what must be done to avoid such loss. Conventional video production techniques that can lead to quality loss regardless of the camera technology used are also identified. A number of recommendations are offered that will help the videographer in an educational or production environment adapt to Internet limitations.

    Full Text Available Dengue virus (DV is the causal pathogen of dengue fever, which is one of the most rapidly spread mosquito-borne disease worldwide and has become a severe public health problem. Currently, there is no specific treatment for dengue; thus, a vaccine would be an effective countermeasure to reduce the morbidity and mortality. Although, the chimeric Yellow fever dengue tetravalent vaccine has been approved in some countries, it is still necessary to develop safer, more effective, and less costly vaccines. In this study, a DNA vaccine candidate pVAX1-D1ME expressing the prME protein of DV1 was inoculated in BALB/c mice via intramuscular injection or electroporation, and the immunogenicity and protection were evaluated. Compared with traditional intramuscular injection, administration with 50 μg pVAX1-D1ME via electroporation with three immunizations induced persistent humoral and cellular immune responses and effectively protected mice against lethal DV1 challenge. In addition, immunization with a bivalent vaccine consisting of pVAX1-D1ME and pVAX1-D2ME via electroporation generated a balanced IgG response and neutralizing antibodies against DV1 and DV2 and could protect mice from lethal challenge with DV1 and DV2. This study sheds new light on developing a dengue tetravalent DNA vaccine.

  6. Minimum dV for Targeted Spacecraft Disposal

    Bacon, John

    2017-01-01

    The density scale height of the Earth's atmosphere undergoes significant reduction in the final phases of a natural decay. It can be shown that for most realistic ballistic numbers, it is possible to exploit this effect to amplify available spacecraft dV by using it at the penultimate perigee to penetrate into higher drag regions at final apogee. The drag at this lower pass can more effectively propel a spacecraft towards the final target region than applying the same dV direct Hohmann transfer at that final apogee. This study analyzes the potential use of this effect-- in combination with small phasing burns--to calculate the absolute minimum delta-V that would be required to reliably guide a spacecraft to any specified safe unoccupied ocean region as a function of ballistic number, orbit inclination, and initial eccentricity. This calculation is made for controllable spacecraft in several orbit inclinations and eccentricities with arbitrary initial LAN and ArgP one week before final entry, under three-sigma atmospheric perturbations. The study analyzes the dV required under varying levels of final controllable altitude at which dV may be imparted, and various definitions of the length and location of a "safe" disposal area. The goal of such research is to improve public safety by creating assured safe disposal strategies for low-dV and/or low-thrust spacecraft that under more traditional strategies would need to be abandoned to a fully random decay.

    DV UMa is an eclipsing dwarf nova with an orbital period of ˜2.06 hr, which lies just at the bottom edge of the period gap. To detect its orbital period changes, we present 12 new mid-eclipse times by using our CCD photometric data and archival data. The latest version of the O-C diagram, combined with the published mid-eclipse times in quiescence, and spanning ˜30 years, was obtained and analyzed. The best fit to those available eclipse timings shows that the orbital period of DV UMa is undergoing a cyclic oscillation with a period of 17.58(+/- 0.52) years and an amplitude of 71.1(+/- 6.7) s. The periodic variation most likely arises from the light-travel-time effect via the presence of a circumbinary object, because the required energy to drive the Applegate mechanism is too high in this system. The mass of the unseen companion was derived as {M}3\\sin i\\prime =0.025(+/- 0.004) {M}⊙ . If the third body is in the orbital plane (i.e., i\\prime =i=82\\buildrel{\\circ}\\over{.} 9) of the eclipsing pair, this would indicate it is a brown dwarf. This hypothetical brown dwarf is orbiting its host star at a separation of ˜8.6 au in an eccentric orbit (e = 0.44).

    The salt-tolerant green alga Dunaliella has remarkable capability to survive in some extreme environments such as nitrogen starvation, which makes Dunaliella be a proper model for mining novel genes on nitrogen uptake or assimilation. In this study, a glutamine synthetase (GS) gene DvGS2 with amino acid identity of 72% to other homologous GS proteins, was isolated and characterized from Dunaliella viridis. Phylogenetic comparison with other GSs revealed that DvGS2 occupied an independent phylogenetic position. Expressional analysis in D. viridis cells under nitrogen starvation confirmed that DvGS2 increased its mRNA level in 12h. Subcellular localization study and functional analysis in a GS-deficient Escherichia coli mutant proved that DvGS2 was a chloroplastic and functional GS enzyme. In order to investigate the potential application of DvGS2 in higher plants, the transgenic studies of DvGS2 in Arabidopsis thaliana were carried out. Results showed that the transgenic lines expressed the DvGS2 gene and demonstrated obviously enhanced root length (29%), fresh weight (40%-48% at two concentrations of nitrate supplies), stem length (21%), leaf size (39%) and silique number (44%) in contrast with the wild-type Arabidopsis. Furthermore, the transgenic lines had higher total nitrogen content (35%-43%), total GS activity (39%-45%) and soluble protein concentration (23%-24%) than the wild type. These results indicated that the overexpression of DvGS2 in A. thaliana resulted in higher biomass and the improvement of the host's nitrogen use efficiency.

    To overcome the disadvantage of multilateral ranging method, consider the location algorithm applied realistic environment,based on the characteristics of DV-Hop, an improved three-dimensional localization algorithm was proposed. The algorithm not only transplants DV-Hop localization algorithm from two dimensions to three-dimensional space outside,also taking into account the algorithm beacon node topology and hops on the localization accuracy, and a Multicollinearity-Based 3D DV-Hop Algorithm(MCB3D DV-Hop) was proposed.

    A beacon node selection scheme and a DV-Hop localization algorithm based on hop weighted are proposed to improve the positioning performance in this paper. First of all, by setting a threshold value of signal propagation hop,the beacon nodes whose propagation hop are fewer are retained. Then,a beacon node optimization is followed to eliminate unfavourable beacon nodes which are approximately in a line to avoid positioning failure. Besides, based on the relationship between distance estimation error and signal propagation hop derived from Friis model,the hop weighted localization algorithm is obtained. It uses the signal propagation hop as the weighted factors to modify the positioning result that gained through maximum likelihood estimation, which reduces the effect on positioning accuracy brought by distance estimation error. The simulation results show that the proposed method can improve the positioning accuracy by 3% ~5%.%针对DV-Hop定位算法中距离估计误差对定位结果的影响,提出了一种信标节点优选方案和跳数加权DV-Hop定位算法.首先通过设定跳数阈值,保留跳数较少的信标节点,然后剔除近似在一条直线上的信标节点,完成信标节点优选,避免未知节点无法定位的情形.此外,利用Friis模型推导出距离估计误差与信号传播跳数之间的映射关系,采用传播跳数作为加权因子对定位结果进行了修正.仿真结果表明该算法降低了距离估计误差对定位精度的影响,提高了定位精度.

    A lot of key problems need to be studied and solved in the field of WSN,and node self-localization is one of them. In numerous localization algorithms,DV-hop is popular with discussion or referenced localization algorithm,but it takes the results of hops multiplied by network average jumps as the actual distance between the nodes, while the accuracy of calculating the average every hop distance,the character of network, the node density, topology structure,etc are major factors which influence the positioning accuracy of DV-Hop algorithm. We put forward an improved DV-Hop algorithm, area division based semi-auto DV-Hop localization algorithm (ADBSA DV-Hop). Several ideas were employed to improve DV-Hop, including semi-auto average size of per hop acquirement,area division, and sticking to border. ADBSA DV-Hop was simulated on MATLAB platform, to compare with DV-Hop. Experiment indictes that ADBSA DV-Hop performs better than DV-Hop,and competently meets the localization requirement of sticking to border.%在WSN领域中有很多亟待研究和解决的关键问题,节点的自我定位是其中之一.在众多定位算法中,DV-HOP是广受讨论或引用的定位算法,但该算法使用跳数乘以网络平均跳距来代替节点间的实际距离,而平均每跳距离的计算精确度与网络的性状、节点密度、拓扑结构等有很大关系,直接影响到DV-HOP算法的定位精度.针对DV-Hop算法这一缺陷,从半自动获取平均每跳距离、划分定位区域和对边缘区域采用坐标贴边三个角度,提出命名为ADBSA DV-Hop的改进的DV-HOP算法.在MATLAB平台上对ADBSA DV-Hop算法与DV-Hop算法进行了对比仿真实验,结果表明,ADBSA DV-Hop算法运行性能好于DV-Hop算法,尤其满足贴边定位情景的需要.

    Mud gas logging has been commonly used in oil industry and continental scientific drilling to detect mainly hydrocarbon gases from the reservoir formation. Quick analysis of the gas provides almost real-time information which is critical to evaluate the formation and, in particular, safety of drilling operation. Furthermore, mud gas monitoring complements the lack of core or fluid samples particularly in a deep hole, and strengthen interpretations of geophysical logs. In scientific ocean drilling, on the other hand, mud gas monitoring was unavailable in riserless drilling through the history of DSDP and ODP, until riser drilling was first carried out in 2009 by D/V Chikyu. In IODP Exp 319, GFZ installed the same system with that used in continental drilling aboard Chikyu. High methane concentrations are clearly correlated with increased wood content in the cuttings. The system installation was, however, temporary and gas separator was moved during the expedition for a technical reason. In 2011, new mud gas monitoring system was installed aboard Chikyu and was used for the first time in Exp 337. The gas separator was placed on a newly branched bypass mud flow line, and the gas sample was sent to analysis unit equipped with methane carbon isotope analyzer in addition to mass spectrometer and gas chromatograph. The data from the analytical instruments is converted to depth profiles by calculating the lag effects due to mud circulation. Exp 337 was carried out from July 26 to Sep 30, 2011, at offshore Shimokita peninsula, northeast Japan, targeting deep sub-seafloor biosphere in and around coal bed. Data from the hole C0020A, which was drilled to 2466 mbsf with riser drilling, provided insights into bio-geochemical process through the depth of the hole. In this presentation, we show the design of Chikyu's new mud gas monitoring system, with preliminary data from Exp 337.

    Full Text Available The secure location of node is significant in the WSN (Wireless Sensor Networks of the troop frontier defence system. The wormhole attack is a big threat in the secure location. The credibility of the beacon node was used to determine the malicious nodes produced by wormhole attack in the WSN. The estimated method of multibeacon nodes was adopted to improve DV-HOP algorithm after excluding the malicious nodes. In this paper, we compared the basic DV-HOP algorithm and the improved DV-HOP algorithm in the coverage percentage and the error of network localization by simulating. The simulation results indicate that the improved DV-HOP algorithm makes the localization coverage percentage can reach 90% on a certain scale of the network, and it makes the error percentage lower when the number of beacons is different.

    This paper describes DV3D, a Vistrails package of high-level modules for the Ultra-scale Visualization Climate Data Analysis Tools (UV-CDAT) interactive visual exploration system that enables exploratory analysis of diverse and rich data sets stored in the Earth System Grid Federation (ESGF). DV3D provides user-friendly workflow interfaces for advanced visualization and analysis of climate data at a level appropriate for scientists. The application builds on VTK, an open-source, object-oriented library, for visualization and analysis. DV3D provides the high-level interfaces, tools, and application integrations required to make the analysis and visualization power of VTK readily accessible to users without exposing burdensome details such as actors, cameras, renderers, and transfer functions. It can run as a desktop application or distributed over a set of nodes for hyperwall or distributed visualization applications. DV3D is structured as a set of modules which can be linked to create workflows in Vistrails. Figure 1 displays a typical DV3D workflow as it would appear in the Vistrails workflow builder interface of UV-CDAT and, on the right, the visualization spreadsheet output of the workflow. Each DV3D module encapsulates a complex VTK pipeline with numerous supporting objects. Each visualization module implements a unique interactive 3D display. The integrated Vistrails visualization spreadsheet offers multiple synchronized visualization displays for desktop or hyperwall. The currently available displays include volume renderers, volume slicers, 3D isosurfaces, 3D hovmoller, and various vector plots. The DV3D GUI offers a rich selection of interactive query, browse, navigate, and configure options for all displays. All configuration operations are saved as Vistrails provenance.

In other words, the character of message exchange between the nodes was introduced to detect the wormhole attacks in this paper. Time property and space property were used to define the valid beacon nodes, along with encryption and authentication mechanisms to resist against the node-tampering attack in the communication process. Finally, the nodes were located securely. The simulation results show that, in hostile environment, the proposed mechanism has a high probability to detect the wormhole attacks, and the relative localization error can be reduced by 63% or so.

    This study reports the cloning and characterization of a novel human phosphatidic acid phosphatase type 2 isoform cDNAs (PAP2d) from the foetal brain cDNA library. The PAP2d gene is localized on chromosome 1p21.3. It contains six exons and spans 112 kb of the genomic DNA. By large-scale cDNA sequencing we found two splice variants of PAP2d, PAP2d_v1 and PAP2d_v2. The PAP2d_v1 cDNA is 1722 bp in length and spans an open reading frame from nucleotide 56 to 1021, encoding a 321aa protein. The PAP2d_v2 cDNA is 1707 bp in length encoding a 316aa protein from nucleotide 56-1006. The PAP2d_v1 cDNA is 15 bp longer than the PAP2d_v2 cDNA in the terminal of the fifth exon and it creates different ORF. Both of the proteins contain a well-conserved PAP2 motif. The PAP2d_v1 is mainly expressed in human brain, lung, kidney, testis and colon, while PAP2d_v2 is restricted to human placenta, skeletal muscle, and kidney. The two splice variants are co-expressed only in kidney.

    We present six new BVR{sub c}I{sub c} CCD light curves of a short-period RS CVn binary DV Psc obtained in 2010-2012. The light curve distortions change on both short and long timescales, which is explained by two starspots on the primary component. Moreover, five new flare events were detected and the flare ratio of DV Psc is about 0.082 flares per hour. There is a possible relation between the phases (longitude) of the flares and starspots for all of the available data of late-type binaries, which implies a correlation of the stellar activity of the spots and flares. The cyclic oscillation, with a period of 4.9 ± 0.4 yr, may result from the magnetic activity cycle, identified by the variability of Max. I-Max. II. Until now, there were no spectroscopic studies of chromospheric activity indicators of the H{sub β} and H{sub γ} lines for DV Psc. Our observations of these indicators show that DV Psc is active, with excess emissions. The updated O – C diagram with an observing time span of about 15 yr shows an upward parabola, which indicates a secular increase in the orbital period of DV Psc. The orbital period secularly increases at a rate of dP/dt = 2.0×10{sup –7} days yr{sup –1}, which might be explained by the angular momentum exchanges or mass transfer from the secondary to primary component.

It is based on state of the art and well maintained Python modules, among which ObsPy plays an important role. To our knowledge, it is officially used for continuous monitoring at least in three notable places: the Observatory of the Piton de la Fournaise volcano (OVPF, France), the Auckland Volcanic Field (New Zealand) and on the South Napa earthquake (Berkeley, USA). It is also used by many researchers to process archive data, e.g. focussing on fault zones, intraplate Europe, geothermal exploitations or Antarctica. We first present the general working of MSNoise, originally written in 2010 to automatically scan data archives and process seismic data in order to produce dv/v time series. We demonstrate that its modularity provides a new potential to easily test new algorithms for each processing step. For example, to experiment new methods of cross-correlation (done by default in the frequency domain), stacking (default is linear stacking, averaging), or dt/t or dv/v estimation (default is moving window cross-spectrum "MWCS", so-called "doublet"), etc. Finally, we present the last major evolution of MSNoise, from a "single workflow: data archive to dv/v" to a framework system that allows plugins and modules to be developed and integrated into the MSNoise ecosystem. Examples of plugins in development such as continuous PPSD (à la McNamarra & Buland) or continuous RSAM/SSAM (Endo & Murray, Stephens) will be presented.

    Naphthalene degrading bacterial consortium (DV-AL) was developed by enrichment culture technique from sediment collected from the Alang-Sosiya ship breaking yard, Gujarat, India. The 16S rRNA gene based molecular analyzes revealed that the bacterial consortium (DV-AL) consisted of four strains namely, Achromobacter sp. BAB239, Pseudomonas sp. DV-AL2, Enterobacter sp. BAB240 and Pseudomonas sp. BAB241. Consortium DV-AL was able to degrade 1000 ppm of naphthalene in Bushnell Haas medium (BHM) containing peptone (0.1%) as co-substrate with an initial pH of 8.0 at 37°C under shaking conditions (150 rpm) within 24h. Maximum growth rate and naphthalene degradation rate were found to be 0.0389 h(-1) and 80 mg h(-1), respectively. Consortium DV-AL was able to utilize other aromatic and aliphatic hydrocarbons such as benzene, phenol, carbazole, petroleum oil, diesel fuel, and phenanthrene and 2-methyl naphthalene as sole carbon source. Consortium DV-AL was also efficient to degrade naphthalene in the presence of other pollutants such as petroleum hydrocarbons and heavy metals.

    DV-Hop 算法中,平均每跳距离是影响定位精度的因素之一。针对平均每跳距离带来的定位误差,对锚节点和未知节点的平均每跳距离进行了改进和优化。首先引入遗传算法计算锚节点的平均每跳距离;然后利用跳数小于等于3的锚节点的平均每跳距离加权处理未知节点的平均每跳距离,减少平均每跳距离带来的误差。仿真结果表明,在不增加硬件开销的基础上,改进算法能够有效提高算法的定位精度,并且具有较好的稳定性。%The average per-hop distance is one of the factors which affect the positioning accuracy in DV-Hop algorithm.Aiming at positioning errors caused by the average distance per hop,the average distance per hop of anchor nodes and unknown nodes have been improved and optimized in this paper.First,the average per hop distance of anchor nodes is computed by introducing genetic algorithm;Then the average distance per hop of the unknown node is weighted by using the average distance per hop of anchor nodes which hop count is less than or equal to 3 to reduce errors caused average distance per hop.Ultimately the accuracy of positioning is improved.Simulation results show that without additional hardware cost,the improved algorithm can effectively improve the positioning accuracy of the algorithm and has good stability.

    2004-01-01

    We present high-speed, three-colour photometry of the faint eclipsing cataclysmic variables XZ Eri and DV UMa. We determine the system parameters through two techniques: first, timings of the eclipse contact phases of the white dwarf and bright-spot using the derivative of the light curve; and secondly, a parameterized model of the eclipse fitted to the observed light curve by chi-squared minimisation. For both objects, we prefer the latter method, as it is less affected by photon noise and rapid flickering. For XZ Eri we obtain a mass ratio q = 0.1098 +/- 0.0017 and an orbital inclination i = 80.16 +/- 0.09 degrees. For DV UMa we derive figures of q = 0.1506 +/- 0.0009 and i = 84.24 +/- 0.07 degrees. The secondary star in XZ Eri has a very low mass Mr/Msun = 0.0842 +/- 0.0024, placing it close to the upper limit on the mass of a brown dwarf.

  16. Orchestrating A/P and D/V guidance - A Wnt/Netrin tale.

    2016-01-01

    While ample information was gathered in identifying guidance cues and their downstream mediators, very little is known about how the information from multiple extracellular cues is intracellularly to generate normal patterning. Netrin and Wnt signaling pathways play key roles in normal development as well as in malignancies. In C. elegans, as in vertebrates, dorso-ventral (D/V) graded distributions of UNC-6/Netrin and antero-posterior (A/P) graded distributions of Wnts provide instructive polarity information to guide cells and axons along their respective gradients. In this commentary, I will discuss recent findings demonstrating that these 2 signaling pathways also function redundantly to regulate polarity orthogonal to the axis of their gradation. Thus, Wnt signaling components contribute to D/V polarity, while Netrin signaling components contribute to A/P polarity and their joint action collaboratively governs migratory transitions from one axis to the other. These findings pave the way to unraveling broader roles of Wnt and Netrin signaling pathways, roles that are masked due to their redundant nature, and provide a conceptually novel view of how antero-posterior and dorso-ventral guidance mechanisms are orchestrated to establish polarity in multiple biological processes.

    Full Text Available The node localization technology of wireless sensor networks is essential and prerequisite to many applications, which it is one of the important support technologies for wireless sensor networks. The node localization is to get the position information of blind node by using location information of few known nodes and some special mechanisms. This paper primarily investigates a kind of target localization technology based on the improved DV-Hop algorithm in wireless sensor networks. We firstly compute the distances measured by RSSI and the mean value of one-hop distance. Then we can use the differences between the mean and the actual distance to get the error correction between the total distance and average one-hop distance. Replace trilateration with hybrid localization of MIN-MAX and weighted least square method. Finally, simulation experiment results show the improved algorithm can effectively carry out the network localization, thus has a certain of practical value

    2013-01-01

    Aiming at the problem that the ranging error of DV-HOP algorithm gets greater as the distance of beacon away from the unknown node,a weighted hyperbolic positioning DV-HOP algorithm is proposed based on triangle inequality.On the basis of calculating distance between beacons and distance between unknown nodes and singlehop beacons,the algorithm takes advantage of triangle inequality to constrain the distance between unknown nodes and multi-hop beacons for the purpose of reducing ranging error.Besides,in order to reduce the influence of ranging error on positioning accuracy,a weight which is inversely proportional to the distance is introduced into the hyperbolic positioning.The simulation experiments show that the proposed algorithm is stable,reliable and achievable.Compared with original DV-HOP and related improved DV-HOP,positioning accuracy respectively increased by 13% and 7% under the same conditions.%针对DV-HOP算法中信标距未知节点越远其测距误差越大的问题,提出了一种基于三角不等式的加权双曲线定位DV-HOP算法.该算法在计算信标间的距离和未知节点到一跳信标距离的基础上,利用三角不等式对未知节点到多跳信标的距离进行约束,以减小测距误差.在双曲线定位过程中引入一个与距离成反比的权值,以降低测距误差对节点定位精度的影响.仿真实验表明,在相同的条件下,与DV-HOP及相关改进算法相比,定位精度分别提高了13%和7%以上,且稳定可靠、易于实现.

    Full Text Available The overexpression of the algal glutamine synthetase (GS gene DvGS1 in Arabidopsis thaliana resulted in higher plant biomass and better growth phenotype. The purpose of this study was to recognize the biological mechanism for the growth improvement of DvGS1-transgenic Arabidopsis. A series of molecular and biochemical investigations related to nitrogen and carbon metabolism in the DvGS1-transgenic line was conducted. Analysis of nitrogen use efficiency (NUE-related gene transcription and enzymatic activity revealed that the transcriptional level and enzymatic activity of the genes encoding GS, glutamate synthase, glutamate dehydrogenase, alanine aminotransferase and aspartate aminotransferase, were significantly upregulated, especially from leaf tissues of the DvGS1-transgenic line under two nitrate conditions. The DvGS1-transgenic line showed increased total nitrogen content and decreased carbon: nitrogen ratio compared to wild-type plants. Significant reduced concentrations of free nitrate, ammonium, sucrose, glucose and starch, together with higher concentrations of total amino acids, individual amino acids (glutamate, aspartate, asparagine, methionine, soluble proteins and fructose in leaf tissues confirmed that the DvGS1-transgenic line demonstrated a higher efficiency of nitrogen assimilation, which subsequently affected carbon metabolism. These improved metabolisms of nitrogen and carbon conferred the DvGS1-transgenic Arabidopsis higher NUE, more biomass and better growth phenotype compared with the wild-type plants.

    [1] We develop a global-scale P wave velocity model (LLNL-G3Dv3) designed to accurately predict seismic travel times at regional and teleseismic distances simultaneously. The model provides a new image of Earth's interior, but the underlying practical purpose of the model is to provide enhanced seismic event location capabilities. The LLNL-G3Dv3 model is based on ∼2.8 millionP and Pnarrivals that are re-processed using our global multiple-event locator called Bayesloc. We construct LLNL-G3Dv3 within a spherical tessellation based framework, allowing for explicit representation of undulating and discontinuous layers including the crust and transition zone layers. Using a multiscale inversion technique, regional trends as well as fine details are captured where the data allow. LLNL-G3Dv3 exhibits large-scale structures including cratons and superplumes as well numerous complex details in the upper mantle including within the transition zone. Particularly, the model reveals new details of a vast network of subducted slabs trapped within the transition beneath much of Eurasia, including beneath the Tibetan Plateau. We demonstrate the impact of Bayesloc multiple-event location on the resulting tomographic images through comparison with images produced without the benefit of multiple-event constraints (single-event locations). We find that the multiple-event locations allow for better reconciliation of the large set of direct P phases recorded at 0–97° distance and yield a smoother and more continuous image relative to the single-event locations. Travel times predicted from a 3-D model are also found to be strongly influenced by the initial locations of the input data, even when an iterative inversion/relocation technique is employed.

    Molecular-orbital calculations for materials design such as alloys, ceramics, and coordination compounds are now possible for experimentalists. Molecuar-orbital calculations for the interpretation of chemical effect of spectra are also possible for experimentalists. The most suitable molecular-orbital calculation method for these purpose is the DV-Xa method, which is robust in such a way that the calculation converges to a result even if the structure of the molecule or solid is impossible in the pressure and temperature ranges on earth. This book specially addresses the methods to design novel materials and to predict the spectralline shape of unknown materials using the DV-Xa molecular-orbital method, but is also useful for those who want to calculate electronic structures of materials using any kind of method.

By analyzing two independent dv1 alleles we demonstrate that this phenotype is caused by mutations in a member of the kinesin-14A subfamily, a class of C-terminal, minus-end directed microtubule motors. Further analysis demonstrates that defects in early spindle assembly are rare, but that later stages of spindle organization promoting the formation of finely focu...

    Directory of Open Access Journals (Sweden)

    Steven L Levine

    Full Text Available In recent years, corn rootworm (CRW-resistant maize events producing two or more CRW-active Bt proteins have been commercialized to enhance efficacy against the target pest(s by providing multiple modes of action (MoA. The maize hybrid MON 87411 has been developed that produces the CRW-active Cry3Bb1 Bt protein (hereafter Cry3Bb1 and expresses a RNAi-mediated MoA that also targets CRW. As part of an environmental risk assessment for MON 87411, the potential for an interaction between the CRW-active DvSnf7 RNA (hereafter DvSnf7 and Cry3Bb1 was assessed in 12-day diet incorporation bioassays with the southern corn rootworm (SCR, Diabrotica undecimpunctata howardi. The potential for an interaction between DvSnf7 and Cry3Bb1 was evaluated with two established experimental approaches. The first approach evaluated each substance alone and in combination over three different response levels. For all three response levels, observed responses were shown to be additive and not significantly different from predicted responses under the assumption of independent action. The second approach evaluated the potential for a fixed sub-lethal concentration of Cry3Bb1 to decrease the median lethal concentration (LC50 of DvSnf7 and vice-versa. With this approach, the LC50 value of DvSnf7 was not altered by a sub-lethal concentration of Cry3Bb1 and vice-versa. In addition, the potential for an interaction between the Cry3Bb1 and DvSnf7 was tested with Colorado potato beetle (CPB, Leptinotarsa decemlineata, which is sensitive to Cry3Bb1 but not DvSnf7. CPB assays also demonstrated that DvSnf7 does not alter the activity of Cry3Bb1. The results from this study provide multiple lines of evidence that DvSnf7 and Cry3Bb1 produced in MON 87411 have independent action.

    Full Text Available An irradiation program DV50 was carried out from 2002 to 2006 in the OSIRIS material testing reactor (CEA-Saclay center to assess the pressure vessel steel toughness curve for a fast neutron fluence (E > 1 MeV equivalent to a French 900-MWe PWR lifetime of 50 years. This program allowed the irradiation of 120 specimens out of vessel steel, subdivided in two successive irradiations DV50 n∘1 and DV50 n∘2. To measure the fast neutron fluence (E > 1 MeV received by specimens after each irradiation, sample holders were equipped with activation foils that were withdrawn at the end of irradiation for activity counting and processing. The fast effective cross-sections used in the dosimeter processing were determined with a specific calculation scheme based on the Monte-Carlo code TRIPOLI-3 (and the nuclear data ENDF/B-VI and IRDF-90. In order to put vessel-steel experiments at the same standard, a new dosimetric interpretation of the DV50 experiment has been performed by using the Monte-Carlo code TRIPOLI-4 and more recent nuclear data (JEFF3.1.1 and IRDF-2002. This paper presents a comparison of previous and recent calculations performed for the DV50 vessel-steel experiment to assess the impact on the dosimetric interpretation.

Further analysis demonstrates that defects in early spindle assembly are rare, but that later stages of spindle organization promoting the formation of finely focused spindle poles are strongly dependent on Dv1. Anaphase is error-prone in dv1 lines but not severely so, and the majority of cells show normal chromosome segregation. Live-cell imaging of wild type and mutant plants carrying CFP-tagged β-tubulin confirm that meiosis in dv1 lines fails primarily at the pole-sharpening phase of spindle assembly. These data indicate that plant kinesin-14A proteins help to enforce bipolarity by focusing spindle poles and that this stage of spindle assembly is not required for transition through the spindle checkpoint but improves the accuracy of chromosome segregation.

    The clinical picture of catatonia includes impressive motor phenomena, such as rigidity, dyskinesia, festination, negativism, posturing, catalepsy, stereotypies and mannerisms, along with affective (e. g. aggression, anxiety, anhedonism or emotional lability) and behavioral symptoms (e.g. mutism, autism, excitement, echolalia or echopraxia). In English speaking countries seven catatonia rating scales have been introduced, which are widely used in clinical and scientific practice. In contrast, only one validated catatonia rating scale is available in Germany so far. In this paper, we introduce the German version of the Northoff catatonia rating scale (NCRS-dv). The original English version of the NCRS consists of 40 items describing motor (13 items), affective (12 items) and behavioral (15 items) catatonic symptoms. The NCRS shows high internal reliability (Crombachs alpha = 0.87), high interrater (r = 0.80-0.96) and high intrarater (r = 0.80-0.95) reliability. Factor analysis of the NCRS revealed four domains: affective, hyperactive or excited, hypoactive or retarded and behavior with individual eigenvalues of 8.98, 3.61, 2.98 and 2.82, respectively, which explained 21.5 %, 9.3 %, 7.6 % and 7.2 % of variance, respectively. In conclusion, the NCRS-dv represents a second validated instrument which can be used by German clinicians and scientists for the assessment of catatonic symptoms.

    无线传感器网络节点定位算法的精度多依赖于信标节点的密度,但信标节点成本高,约为普通节点的100倍以上,为了降低定位的成本,提出了一种基于移动信标和DV-Hop的无线传感器网络节点定位算法(MBWDV-Hop).该算法在DV-Hop定位算法的基础上,利用一个移动的信标节点在网络中按预定的路径移动并不断地广播自己的位置信息,形成多个虚拟信标,未知节点记录到每个虚拟信标的跳数,并采用加权处理的方法计算平均跳距及其与各虚拟信标的距离,最后利用三边测量法计算未知节点的位置信息,实现节点精确定位.由于只采用一个移动信标,降低了定位的成本和布网的复杂度.最后通过仿真证明算法可以提高定位精度,降低定位成本,提高了定位的效率.%The precision of localisation algorithm for wireless sensor networks mostly relies on the density of beacon node, but the beacon node is very expensive, approximately more than 100 times of the ordinary node. In order to curtail the cost of localisation, we propose a kind of WSN localisation algorithm based on mobile beacon and DV-Hop (MBWDV-Hop). In this algorithm, on the basis of DV-Hop localisation algorithm, a mobile beacon node is used to move around the network according to destined path and to broadcast continually the messages with regard to its own localisation, and this forms a lot of virtual beacons in network. The unknown node records the number of hops from each virtual beacon and uses weighedprocessing method to calculate the average of one-hop distance and the distances between it itself and each virtual beacon. At the end, trilateration method is used to calculate the position information of the unknown node to achieve accurate localisation of the node. Since only one mobile beacon is used in this algorithm, the cost of localisation and the complexity of network deployment can be reduced. Simulation result demonstrates that

    通过分析传统 DV-Hop 定位算法在对无线传感器网络中节点分布随机性方面的不足,提出了一种改进算法。该算法采用最小均方误差准则代替方差或偏差,求得平均每跳距离。为了体现各信标节点对未知节点的影响程度不同,采用反距离加权法来处理平均每跳距离。实验结果表明,在没有增加原算法复杂度和成本的前提下,定位精度有了一定提高,该算法是一种简单实用的改进定位算法。%An improved algorithm was proposed by analyzing the deficiencies of traditional DV-Hop algorithm in terms of ran-dom distribution, which owns improvements over two aspects.Firstly, instead of variance or deviation, the average one-hop dis-tance is estimated by minimum mean-squared error criterion (MMSE).Secondly, in order to reflect the different effects of each beacon node on unknown nodes, inverse distance weighting method is adopted to deal with the average one-hop distance.Improved algorithm is simulated on MATLAB platform , and the results show that the positioning accuracy is improved on the condition of no increasing complexity and cost.The improved algorithm is a simple and practical algorithm.

    Background and Methodology There is a continuing need to express new insect control compounds in transgenic maize against western corn rootworm, Diabrotica virgifera virgifera (LeConte) (WCR). In this study three experiments were conducted to determine cross-resistance between the new insecticidal DvSnf7 dsRNA, and Bacillus thuringiensis (Bt) Cry3Bb1; used to control WCR since 2003, with field-evolved resistance being reported. Laboratory susceptible and Cry3Bb1-resistant WCR were evaluated against DvSnf7 dsRNA in larval diet-incorporation bioassays. Additionally, the susceptibility of seven field and one field-derived WCR populations to DvSnf7 (and Cry3Bb1) was assessed in larval diet-overlay bioassays. Finally, beetle emergence of laboratory susceptible and Cry3Bb1-resistant WCR was evaluated with maize plants in the greenhouse expressing Cry3Bb1, Cry34Ab1/Cry35Ab1, or DvSnf7 dsRNA singly, or in combination. Principal Findings and Conclusions The Cry3Bb1-resistant colony had slight but significantly (2.7-fold; PIRM tool against WCR that will increase the durability of these Bt proteins. These results also illustrate the importance of using appropriate bioassay methods when characterizing field-evolved resistant WCR populations. PMID:28060922

    This paper presents a regional climate system model RCM-CLM-CN-DV and its validation over Tropical Africa. The model development involves the initial coupling between the ICTP regional climate model RegCM4.3.4 (RCM) and the Community Land Model version 4 (CLM4) including models of carbon-nitrogen dynamics (CN) and vegetation dynamics (DV), and further improvements of the models. Model improvements derive from the new parameterization from CLM4.5 that addresses the well documented overestimation of gross primary production (GPP), a refinement of stress deciduous phenology scheme in CN that addresses a spurious LAI fluctuation for drought-deciduous plants, and the incorporation of a survival rule into the DV model to prevent tropical broadleaf evergreens trees from growing in areas with a prolonged drought season. The impact of the modifications on model results is documented based on numerical experiments using various subcomponents of the model. The performance of the coupled model is then validated against observational data based on three configurations with increasing capacity: RCM-CLM with prescribed leaf area index and fractional coverage of different plant functional types (PFTs); RCM-CLM-CN with prescribed PFTs coverage but prognostic plant phenology; RCM-CLM-CN-DV in which both the plant phenology and PFTs coverage are simulated by the model. Results from these three models are compared against the FLUXNET up-scaled GPP and ET data, LAI and PFT coverages from remote sensing data including MODIS and GIMMS, University of Delaware precipitation and temperature data, and surface radiation data from MVIRI and SRB. Our results indicate that the models perform well in reproducing the physical climate and surface radiative budgets in the domain of interest. However, PFTs coverage is significantly underestimated by the model over arid and semi-arid regions of Tropical Africa, caused by an underestimation of LAI in these regions by the CN model that gets exacerbated

  1. Identification of an eccentricity in the date/time metadata of a PAL MiniDV recording.

    2008-11-01

    A Phase-Alternation Line (PAL) Mini Digital Video (MiniDV) recording and camcorder were provided by the Law Society of Singapore for forensic examination. During visual analyses of the submitted recording and a test recording produced on the submitted camcorder, the number of occurrences of each unique date/time stamp varied from the nominal value of 25 frames (the frame rate per second of PAL recordings), within a range of +/-3 frames. This embedded date/time information is recorded in the digital bit stream along with the video and audio information and can be optionally displayed during playback. These visual observations prompted detailed analyses of the digital metadata of the recordings which consisted of locating the portions of the bit stream associated with the date/time information, and then identifying their redundancy characteristics, data structure, and encoding protocol. Automated scripts were developed using digital data analysis software to locate, extract, convert, and count all of the unique date/time stamps, and to provide an easily-viewable output of the results. The application of the scripting process to both the submitted tape and the test recording produced on the submitted camcorder revealed that the date/time information on each exhibited a nonstandard but consistent timing pattern, which confirmed the visual observations and provided evidence that the submitted recording was consistent with having been produced on the submitted camcorder.

    MON 87411 maize, which expresses DvSnf7 RNA, was developed to provide an additional mode of action to confer protection against corn rootworm (Diabrotica spp.). A critical step in the registration of a genetically engineered crop with an insecticidal trait is performing an ecological risk assessment to evaluate the potential for adverse ecological effects. For MON 87411, an assessment plan was developed that met specific protection goals by characterizing the routes and levels of exposure, and testing representative functional taxa that would be directly or indirectly exposed in the environment. The potential for toxicity of DvSnf7 RNA was evaluated with a harmonized battery of non-target organisms (NTOs) that included invertebrate predators, parasitoids, pollinators, soil biota as well as aquatic and terrestrial vertebrate species. Laboratory tests evaluated ecologically relevant endpoints such as survival, growth, development, and reproduction and were of sufficient duration to assess the potential for adverse effects. No adverse effects were observed with any species tested at, or above, the maximum expected environmental concentration (MEEC). All margins of exposure for NTOs were >10-fold the MEEC. Therefore, it is reasonable to conclude that exposure to DvSnf7 RNA, both directly and indirectly, is safe for NTOs at the expected field exposure levels. Copyright © 2016 The Author(s).

    The honey bee (Apis mellifera L.) is the most important managed pollinator species worldwide and plays a critical role in the pollination of a diverse range of economically important crops. This species is important to agriculture and historically has been used as a surrogate species for pollinators to evaluate the potential adverse effects for conventional, biological, and microbial pesticides, as well as for genetically engineered plants that produce pesticidal products. As part of the ecological risk assessment of MON 87411 maize, which expresses a double-stranded RNA targeting the Snf7 ortholog (DvSnf7) in western corn rootworm (Diabrotica virgifera virgifera), dietary feeding studies with honey bee larvae and adults were conducted. Based on the mode of action of the DvSnf7 RNA in western corn rootworm, the present studies were designed to be of sufficient duration to evaluate the potential for adverse effects on larval survival and development through emergence and adult survival to a significant portion of the adult stage. Testing was conducted at concentrations of DvSnf7 RNA that greatly exceeded environmentally relevant exposure levels based on expression levels in maize pollen. No adverse effects were observed in either larval or adult honey bees at these high exposure levels, providing a large margin of safety between environmental exposure levels and no-observed-adverse-effect levels.

    The primary accomplishment of the JOI Cooperative Agreement with DOE/NETL in this quarter was the preparation of tools and measurement systems for deployment, testing and use on ODP Leg 204, which will study hydrate deposits on Hydrate Ridge, offshore Oregon. Additional accomplishments were related to the postcruise evaluation of tools and measurements systems used on ODP Leg 201 along the Peru margin from January through March, 2002. The operational results from the use of the Pressure Core Sampler (PCS) tool and the PCS Gas Manifold on ODP Leg 201 are evaluated in this progress report in order to prepare for the upcoming deployments on ODP Leg 204 in July, 2002. The PCS was deployed 17 times during ODP Leg 201 and successfully retrieved cores from a broad range of lithologies and sediment depths along the Peru margin. Eleven deployments were entirely successful, collecting between 0.5 and 1.0 meters of sediment at greater than 75% of hydrostatic pressure. The PCS gas manifold was used in conjunction with the Pressure Core Sampler (PCS) throughout ODP Leg 201 to measure the total volume and composition of gases recovered in sediment cores associated with methane gas hydrates. The FUGRO Pressure Corer (FPC), one of the HYACE/HYACINTH pressure coring tools, was also deployed on the D/V JOIDES Resolution during ODP Legs 201 to field-test this coring system at three shallow-water sites located offshore Peru. The field-testing of these tools provides a corollary benefit to DOE/NETL at no cost to this project. The testing of these tools on the D/V JOIDES Resolution was negotiated as part of a cooperative agreement between JOI/ODP and the HYACINTH partners. The DVTP, DVTP-P, APC-methane, and APC-Temperature tools (ODP memory tools) were used extensively during ODP Leg 201. The data obtained from the successful deployments of these tools is still being evaluated by the scientists and engineers involved in this testing; however, preliminary results are presented in this

    The primary accomplishments of the JOI Cooperative Agreement with DOE/NETL in this quarter were the deployment of tools and measurement systems for testing on ODP Leg 201, which is intended to study hydrate deposits on the Peru margin as part of other scientific investigations. Additional accomplishments were related to the continuing evolution of tools and measurements systems in preparation for deployment on ODP Leg 204, Hydrate Ridge, offshore Oregon in July 2002. The design for PCS Gas Manifold was finalized and parts were procured to assemble the gas manifold and deploy this system with the Pressure Core Sampler (PCS) tool on ODP Leg 201. The PCS was deployed 17 times during ODP Leg 201 and successfully retrieved cores from a broad range of lithologies and sediment depths along the Peru margin. Eleven deployments were entirely successful, collecting between 0.5 and 1.0 meters of sediment at greater than 75% of hydrostatic pressure. The PCS gas manifold was used in conjunction with the Pressure Core Sampler (PCS) throughout ODP Leg 201 to measure the total volume and composition of gases recovered in sediment cores associated with methane hydrates. The results of these deployments will be the subject of a future progress report. The FUGRO Pressure Corer (FPC), one of the HYACE/HYACINTH pressure coring tools, and two FUGRO engineers were deployed on the D/V JOIDES Resolution during ODP Legs 201 to field-test this coring system at sites located offshore Peru. The HYACINTH project is a European Union (EU) funded effort to develop tools to characterize methane hydrate and measure physical properties under in-situ conditions. The field-testing of these tools provides a corollary benefit to DOE/NETL at no cost to this project. The opportunity to test these tools on the D/V JOIDES Resolution was negotiated as part of a cooperative agreement between JOI/ODP and the HYACINTH partners.

    During International Ocean Discovery Program (IODP) expeditions, shipboard-generated data provide the first insights into the cored sequences. The natural gamma radiation (NGR) of the recovered material, for example, is routinely measured on the ocean drilling research vessel DV JOIDES Resolution. At present, only total NGR counts are readily available as shipboard data, although full NGR spectra (counts as a function of gamma-ray energy level) are produced and archived. These spectra contain unexploited information, as one can estimate the sedimentary contents of potassium (K), thorium (Th), and uranium (U) from the characteristic gamma-ray energies of isotopes in the 40K, 232Th, and 238U radioactive decay series. Dunlea et al. [2013] quantified K, Th and U contents in sediment from the South Pacific Gyre by integrating counts over specific energy levels of the NGR spectrum. However, the algorithm used in their study is unavailable to the wider scientific community due to commercial proprietary reasons. Here, we present a new MATLAB algorithm for the quantification of NGR spectra that is transparent and accessible to future NGR users. We demonstrate the algorithm's performance by comparing its results to shore-based inductively coupled plasma-mass spectrometry (ICP-MS), inductively coupled plasma-emission spectrometry (ICP-ES), and quantitative wavelength-dispersive X-ray fluorescence (XRF) analyses. Samples for these comparisons come from eleven sites (U1341, U1343, U1366-U1369, U1414, U1428-U1430, U1463) cored in two oceans during five expeditions. In short, our algorithm rapidly produces detailed high-quality information on sediment properties during IODP expeditions at no extra cost. Dunlea, A. G., R. W. Murray, R. N. Harris, M. A.

    The primary accomplishments of the JOI Cooperative Agreement with DOE/NETL in this quarter were (1) the preliminary postcruise evaluation of the tools and measurement systems that were used during ODP Leg 204 to study hydrate deposits on Hydrate Ridge, offshore Oregon from July through September 2002; and (2) the preliminary study of the hydrate-bearing core samples preserved in pressure vessels and in liquid nitrogen cryofreezers, which are now stored at the ODP Gulf Coast Repository in College Station, TX. During ODP Leg 204, several newly modified downhole tools were deployed to better characterize the subsurface lithologies and environments hosting microbial populations and gas hydrates. A preliminary review of the use of these tools is provided herein. The DVTP, DVTP-P, APC-methane, and APC-Temperature tools (ODP memory tools) were used extensively and successfully during ODP Leg 204 aboard the D/V JOIDES Resolution. These systems provided a strong operational capability for characterizing the in situ properties of methane hydrates in subsurface environments on Hydrate Ridge during ODP Leg 204. Pressure was also measured during a trial run of the Fugro piezoprobe, which operates on similar principles as the DVTP-P. The final report describing the deployments of the Fugro Piezoprobe is provided in Appendix A of this report. A preliminary analysis and comparison between the piezoprobe and DVTP-P tools is provided in Appendix B of this report. Finally, a series of additional holes were cored at the crest of Hydrate Ridge (Site 1249) specifically geared toward the rapid recovery and preservation of hydrate samples as part of a hydrate geriatric study partially funded by the Department of Energy (DOE). In addition, the preliminary results from gamma density non-invasive imaging of the cores preserved in pressure vessels are provided in Appendix C of this report.

The primary objectives of Phase 2 were to sample and characterize methane hydrates using the systems and capabilities of the D/V JOIDES Resolution during IODP Expedition 311, to enable scientists the opportunity to establish the mass and distribution of naturally occurring gas and gas hydrate at all relevant spatial and temporal scales, and to contribute to the DOE methane hydrate research and development effort. The goal of the work was to provide expanded measurement capabilities on the JOIDES Resolution for a dedicated hydrate cruise to the Cascadia continental margin off Vancouver Island, British Columbia, Canada (IODP Expedition 311) so that hydrate deposits in this region would be well characterized and technology development continued for hydrate research. IODP Expedition 311 shipboard activities on the JOIDES Resolution began on August 28 and were concluded on October 28, 2005. The statement of work for this project included three primary tasks: (1) research management oversight, provided by JOI; (2) mobilization, deployment and demobilization of pressure coring and core logging systems, through a subcontract with Geotek Ltd.; and, (3) mobilization, deployment and demobilization of a refrigerated container van that will be used for degassing of the Pressure Core Sampler and density logging of these pressure cores, through a subcontract with the Texas A&M Research Foundation (TAMRF). Additional small tasks that arose during the course of the research were included under these three primary tasks in consultation with the DOE

    The primary accomplishments during the first quarter were to mobilize materials and supplies to meet the deployment schedule for equipment and activities, as proposed under the DOE/NETL cooperative agreement with JOI, with initial testing and use of specialized tools and equipment on Ocean Drilling Program (ODP) Leg 201. As a requirement of the award, two copies of a technical feasibility report entitled ''Preliminary Evaluation of Existing Pressure/Temperature Coring Systems'' were delivered to DOE/NETL on October 22, 2001. The report was written to provide a discussion of the availability and compatibility of the four existing pressure coring devices in existence. Most of these systems are available for use by JOI/ODP aboard the D/V JOIDES Resolution, via purchase, lease, modification, etc. and the proposed capabilities to upgrade existing devices or systems for use on other platforms. In addition, the report provided a discussion of the compatibility of each existing coring device in conjunction with the use of the other coring devices, such as the advanced piston coring (APC) system used by ODP. Based on an evaluation of the JOI report, the DOE/NETL Program Manager William Gwilliam provided a ''Go'' decision to JOI for the further development of the ODP Pressure Coring System (PCS) and PCS Gas Manifold. During the reporting period negotiations were conducted with various potential subcontractors and vendors to establish the specific cost-sharing arrangements and work breakdown necessary to definitize the terms of the DOE/NETL cooperative agreement with JOI. The discussions were communicated with the DOE/NETL Program Manager, William Gwilliam, to keep NETL closely informed about events as this project evolved. A series of meetings were also held with ODP engineers, technical staff, and to plan for the implementation of the various tasks outlined in the JOI proposal to DOE for deployment during ODP Legs 201 and 204.

  17. A safe vaccine (DV-STM-07 against Salmonella infection prevents abortion and confers protective immunity to the pregnant and new born mice.

    Full Text Available Pregnancy is a transient immuno-compromised condition which has evolved to avoid the immune rejection of the fetus by the maternal immune system. The altered immune response of the pregnant female leads to increased susceptibility to invading pathogens, resulting in abortion and congenital defects of the fetus and a subnormal response to vaccination. Active vaccination during pregnancy may lead to abortion induced by heightened cell mediated immune response. In this study, we have administered the highly attenuated vaccine strain DeltapmrG-HM-D (DV-STM-07 in female mice before the onset of pregnancy and followed the immune reaction against challenge with virulent S. Typhimurium in pregnant mice. Here we demonstrate that DV-STM-07 vaccine gives protection against Salmonella in pregnant mice and also prevents Salmonella induced abortion. This protection is conferred by directing the immune response towards Th2 activation and Th1 suppression. The low Th1 response prevents abortion. The use of live attenuated vaccine just before pregnancy carries the risk of transmission to the fetus. We have shown that this vaccine is safe as the vaccine strain is quickly eliminated from the mother and is not transmitted to the fetus. This vaccine also confers immunity to the new born mice of vaccinated mothers. Since there is no evidence of the vaccine candidate reaching the new born mice, we hypothesize that it may be due to trans-colostral transfer of protective anti-Salmonella antibodies. These results suggest that our vaccine DV-STM-07 can be very useful in preventing abortion in the pregnant individuals and confer immunity to the new born. Since there are no such vaccine candidates which can be given to the new born and to the pregnant women, this vaccine holds a very bright future to combat Salmonella induced pregnancy loss.

    Full Text Available The article presents results of specialized processing of the deep seismic profile along a part of Reference Profile 3-DV which crosses the Aldan-Stanovoi shield in the meridian direction and goes across its buried northern slope. The study is aimed at determining frequency-energy characteristics of the seismic wave field which are related to physical conditions of geological features of the crust. Based on analysis and interpretation of the dynamic profiles, it is possible to reveal and contour the Archean cores of consolidation of the Aldan shield and its buried continuation that is covered by sediments of the Middle Lena monocline and to input new facts in the proposed geodynamic model showing formation of the crust in the south-eastern segment of the North Asian craton.

  2. Concentration profiles for fine and coarse sediments suspended by waves over ripples: An analytical study with the 1-DV gradient diffusion model

    CERN Document Server

    2010-01-01

    Field and laboratory measurements of suspended sediments over wave ripples show, for time-averaged concentration profiles in semi-log plots, a contrast between upward convex profiles for fine sand and upward concave profiles for coarse sand. Careful examination of experimental data for coarse sand shows a near-bed upward convex profile beneath the main upward concave profile. Available models fail to predict these two profiles for coarse sediments. The 1-DV gradient diffusion model predicts the main upward concave profile for coarse sediments thanks to a suitable $\\beta$(y)-function (where $\\beta$ is the inverse of the turbulent Schmidt number and y is the distance from the bed). In order to predict the near-bed upward convex profile, an additional parameter {\\alpha} is needed. This parameter could be related to settling velocity ($\\alpha$ equal to inverse of dimensionless settling velocity) or to convective sediment entrainment process. The profiles are interpreted by a relation between second derivative of ...

  3. Ventralization of an indirect developing hemichordate by NiCl₂ suggests a conserved mechanism of dorso-ventral (D/V) patterning in Ambulacraria (hemichordates and echinoderms).

    One of the earliest steps in embryonic development is the establishment of the future body axes. Morphological and molecular data place the Ambulacraria (echinoderms and hemichordates) within the Deuterostomia and as the sister taxon to chordates. Extensive work over the last decades in echinoid (sea urchins) echinoderms has led to the characterization of gene regulatory networks underlying germ layer specification and axis formation during embryogenesis. However, with the exception of recent studies from a direct developing hemichordate (Saccoglossus kowalevskii), very little is known about the molecular mechanism underlying early hemichordate development. Unlike echinoids, indirect developing hemichordates retain the larval body axes and major larval tissues after metamorphosis into the adult worm. In order to gain insight into dorso-ventral (D/V) patterning, we used nickel chloride (NiCl₂), a potent ventralizing agent on echinoderm embryos, on the indirect developing enteropneust hemichordate, Ptychodera flava. Our present study shows that NiCl₂ disrupts the D/V axis and induces formation of a circumferential mouth when treated before the onset of gastrulation. Molecular analysis, using newly isolated tissue-specific markers, shows that the ventral ectoderm is expanded at expense of dorsal ectoderm in treated embryos, but has little effect on germ layer or anterior-posterior markers. The resulting ventralized phenotype, the effective dose, and the NiCl₂ sensitive response period of Ptychodera flava, is very similar to the effects of nickel on embryonic development described in larval echinoderms. These strong similarities allow one to speculate that a NiCl₂ sensitive pathway involved in dorso-ventral patterning may be shared between echinoderms, hemichordates and a putative ambulacrarian ancestor. Furthermore, nickel treatments ventralize the direct developing hemichordate, S. kowalevskii indicating that a common pathway patterns both larval and adult

    Objective To analyze the influencing factors of velocity during removal of virus in human immunoglobulin for intra-venous injection(IVIG) by DV50 nanofiltration. Methods The turbidity and concentration of bulk of IVIG were determined by tur-bidimeter and densimeter respectively. Five batches of bulks with similar concentrations and different turbidities, as well as five batches of bulks with similar turbidities and different concentrations, were subjected to nanofiltration by using the filter elements of the same batch, and the mean velocity was calculated. Another five batches of bulks with similar turbidities and concentrations were sub-jected to nanofiltration by using the filter elements of different batches, and the mean velocity was calculated. Results The mean velocity decreased with the increasing turbidity of bulk, while showed no linear relationship to the concentration. The mean velocity of nanofil-tration by using various filter elements showed significant difference. Conclusion The turbidity of product showed a cer-tain influ-ence, while the concentration showed no significant difference,on velocity. However, the filter element showed significant influence on velocity. The study provided a reference to controlling the velocity during removal of virus by nanofiltration and improv-ing the pro-duction procedure of IVIG.%目的 分析DV50纳米过滤去除静注入免疫球蛋白(Human immunoglobulin for intravenous injection,IVIG)病毒时流速的影响因素.方法 分别采用浊度仪、密度仪检测IVIG原液的浊度及浓度,随机选取5批浓度相近、浊度不同的IVIG原液及5批浊度相近、浓度不同的IVIG原液,分别经同一批号纳米滤芯过滤,计算平均流速;随机选取5批浊度、浓度相近的IVIG 原液,经不同批号的纳米滤芯过滤,计算平均流速.结果 随着制品浊度的升高,平均流速逐渐降低;制品浓度与平均流速不呈线性对应关系;不同批号的纳米滤芯,纳米平

    Full Text Available During the Integrated Ocean Drilling Program (IODP Expedition 331 at the Iheya North hydrothermal system in the Mid-Okinawa Trough by the D/V Chikyu, we conducted microbiological contamination tests of the drilling and coring operations. The contamination from the drilling mud fluids was assessed using both perfluorocarbon tracers (PFT and fluorescent microsphere beads. PFT infiltration was detected from the periphery of almost all whole round cores. By contrast, fluorescent microspheres were not detected in hydrothermally active core samples, possibly due to thermal decomposition of the microspheres under high-temperature conditions. Microbial contamination from drilling mud fluids to the core interior subsamples was further characterized by molecular-based evaluation. The microbial 16S rRNA gene phylotype compositions in the drilling mud fluids were mainly composed of sequences of Beta- and Gammaproteobacteria, and Bacteroidetes and not archaeal sequences. The phylotypes that displayed more than 97% similarity to the sequences obtained from the drilling mud fluids were defined as possible contaminants in this study and were detected as minor components of the bacterial phylotype compositions in 13 of 37 core samples. The degree of microbiological contamination was consistent with that determined by the PFT and/or microsphere assessments. This study suggests a constructive approach for evaluation and eliminating microbial contamination during riser-less drilling and coring operations by the D/V Chikyu.

    The effects of the specific blockers of the inward Na-current --lidocaine and tetrodotoxin (TTX) were studied with microelectrode technique on the spontaneously beating strips of the mouse sinoauricular (SA) area. Lidocaine (25 microM) and TTX (25 pM) increased the duration of the peak of the action potentials (AP) of true pacemaker cells by extending the plateau phase (phase 2 or APD 20), slowing the dV/dt max from 2.6 +/- 0.8 V/s (n = 25) to 1.4 +/- 0.3 V/s (n = 5, p lidocaine concentration. The experimental data fully meted to Hill equation. The lidocaine threshold concentration was 20 microM. The lidocaine effective concentration which decreased dV/dt max by 50% (EC50) was 35 microM. The TTX (25 microM) exposure decreased the dV/dt max from 1.6 V/s to 0.8 V/s and DD velocity slowed by 49%. It should be noted that TTX also increased the duration of APD20. Our data show that dV/ dt max of the true pacemaker cells was reduced by 35-45% after exposure to TTX and lidocaine. This fact confirms the involvement of Na-current in the generation of the upstroke true pacemaker cells AP.

    Volkov, D. V.

    Q. Dmitry Vasilyevich, could you tell me, please, what was your path into theoretical physics, how did you become a theoretician, and was this accidental or was there any specific cause. A. I was born in Leningrad. When I was 16 years old and when I was studying in the 8th grade, the Great Patriotic War began. I was evacuated from Leningrad. These were very difficult years for young people. In this period I came to work on a collective farm and in a military factory. After that I was drafted into the army and took part as a soldier in the war on the Karelian front, above the polar circle. When the war began with Japan, I participated in military action on the Far Eastern front. I want to say that the war had a considerable influence on my attitude to life. In my generation the war created a feeling of responsibility for the country. After the war we carried over the same ideology into civilian life. When the question of a choice of profession arose, many of us thought about how we might be useful to our country. During all the war years I dreamed about going into science, because already in school I was attracted especially to the exact sciences: mathematics and physics. After the demobilization I entered Leningrad State University, in the faculty of physics. At that time prominent scientists such as V.A. Fock and T.P. Kravets were teaching there. The lectures of T.P. Kravets were distinguished by his ability to link the study material with personal moments. He taught us that physics is created by living people and he spoke much about his teacher Lebedev. From the first days Kravets infected us with a deep love for science, and for physics in particular. Aside from that, I listened to the lectures of V.I. Smirnov, whose widely known multi-volume works were specially intended for theoretical physicists, and, in fact, formed the basis of our whole education. We learned a lot from other mathematicians of his school: O.A. Ladyzhenskaya, M.I. Petrashen. In the final year I received a profound training in the specialization of theoretical physics thanks to the excellent teacher L.E. Gurevich. There were also other teachers, which I remember to this time with thankfulness…

    Using dispersion corrected density functional theory (DFT+D), the interaction of Vanadium adatom and cluster with divacancy (555-777) defective graphene sheet has been studied elaborately. We explore the prospect of hydrogen storage on V{sub 4} cluster adsorbed divacancy graphene system. It has been observed that V{sub 4} cluster (acting as a catalyst) can dissociate the H{sub 2} molecule into H atoms with very low barrier energy. We introduce the spillover of the atomic hydrogen throughout the surface via external mediator gallane (GaH{sub 3}) to form a hydrogenated system.

    Full Text Available This article centres around the Czechoslovakian perception of holiday travel to Yugoslavia in the 1920s with particular attention to the typology of Czech tourists. It has been shown that travel to Yugoslavia was very popular among the middle classes who had enough time and money. The wealthier classes preferred France. The main selling points travel agents and hotel owners used to promote travel to Yugoslavia were affordability, service targeted to Czechs and Pan-slavism. The idea of a mutual Slavonic tradition had been in existence since the 19th century. Evidence would seem to show that the most significant factor for repeat travel was affordability. Conservative Czech tourists remained loyal guests of Yugoslavia during the 1920s and 1930s.

Velký počet veteránů z druhé světové války způsobil významné změny v přístupu k pohybovým aktivitám osob se zdravotním postižením. Toto později vedlo k oddělení korektivní fyzioterapie od aplikované tělesné výchovy v roce 1952. Adapted physical education in the U. S. has evolved from medical, corrective gymnastics. The original influence of Swedish gymnastics was passed on to American Universities via Hartwig Nissen (1855–1924, Nils Posse (1862–1895 and William Skarstrom (1896–1951. The first American leaders of corrective gymnastics were Lillian Curtis Drew and Louisa Lippitt. The corrective approach was the philosophy of physical education for students with special needs from the 1920 till the 1950. Leaders of APE in that era were Charles Lowman (1879–1977, George Stafford (1894–1968 and Josephine Rathbone (1899–1989. They very closely cooperated with physical therapists. A great number of World War II veterans influenced the major changes in sport for people with disabilities. World War II significantly changed the approach to physical activities for people with disabilities, which led to the separation of corrective physical therapy and adapted physical education in 1952.

    Full Text Available The general character of the memory of the contemporary witnesses and the fact that nearly no Christian samizdat of the 1960s has been preserved do not allow to offer a closer look to the topics discussed by the priests released from prison with their friends. We can only offer it through the witness of one of them, Antonín Mandl (1917–1972. His work from 1965 to 1967 is only a voice of an individual, but we can suppose that it echoes a broader debate, in which the experience of the earlier years has been confronted both with the contemporary form of the Czechoslovak society ruled by the Communist totalitarian regime and with the results of the Vatican Council II. The paper focuses on Mandl’s answer to the following three questions: In the relation to the Communism, is it proper to choose opposition, or collaboration? How should the priesthood in the contemporary society look like? What are the major axioms of Christian life, pastoral work and evangelisation?

    2002-09-30

    The primary accomplishment of the JOI Cooperative Agreement with DOE/NETL in this quarter was the deployment of tools and measurement systems on ODP Leg 204 to study hydrate deposits on Hydrate Ridge, offshore Oregon from July through September, 2002. During Leg 204, we cored and logged 9 sites on the Oregon continental margin to determine the distribution and concentration of gas hydrates in an accretionary ridge and adjacent slope basin, investigate the mechanisms that transport methane and other gases into the gas hydrate stability zone (GHSZ), and obtain constraints on physical properties of hydrates in situ. A 3D seismic survey conducted in 2000 provided images of potential subsurface fluid conduits and indicated the position of the GHSZ throughout the survey region. After coring the first site, we acquired Logging-While-Drilling (LWD) data at all but one site to provide an overview of downhole physical properties. The LWD data confirmed the general position of key seismic stratigraphic horizons and yielded an initial estimate of hydrate concentration through the proxy of in situ electrical resistivity. These records proved to be of great value in planning subsequent coring. The second new hydrate proxy to be tested was infrared thermal imaging of cores on the catwalk as rapidly as possible after retrieval. The thermal images were used to identify hydrate samples and to map estimate the distribution and texture of hydrate within the cores. Geochemical analyses of interstitial waters and of headspace and void gases provide additional information on the distribution and concentration of hydrate within the stability zone, the origin and pathway of fluids into and through the GHSZ, and the rates at which the process of gas hydrate formation is occurring. Bio- and lithostratigraphic description of cores, measurement of physical properties, and in situ pressure core sampling and thermal measurements complement the data set, providing ground-truth tests of inferred physical and sedimentological properties. Among the most interesting preliminary results are: (1) the discovery that gas hydrates are distributed through a broad depth range within the GHSZ and that different physical and chemical proxies for hydrate distribution and concentration give generally consistent results; (2) evidence for the importance of sediment properties for controlling the migration of fluids in the accretionary complex; (3) geochemical indications that the gas hydrate system at Hydrate Ridge contains significant concentrations of higher order hydrocarbons and that fractionation and mixing signals will provide important constraints on gas hydrate dynamics; and (4) the discovery of very high chlorinity values that extend for at least 10 mbsf near the summit, indicating that hydrate formation here must be very rapid.

    Gel Permeation Chromatography (GPC) was used to analyze poly(arylene ether phosphine oxide)s whose backbones were identical except for the ketone content and placement. These samples were exposed to low Earth orbit environment (predominantly atomic oxygen) on space shuttle flights. The materials and their unexposed controls were then characterized by GPC to investigate the effect of atomic oxygen on the molecular weight distributions. Analysis of the soluble portion of the samples revealed that there was significant loss of high molecular weight species. The presence of insoluble material also suggested that crosslinking was induced by the atomic oxygen exposure and that this very likely occurred at the high molecular weight portion of the molecular weight distribution.

At the EGS/EUG/AGU meeting in Nice, France in April, Leg 204 Co-chiefs Anne Trehu and Gerhard Bohrmann, as well as ODP scientists Charlie Paull, Erwin Suess, and Jim Kennett, participated in a press conference on hydrates. The well-attended press conference entitled ''Gas Hydrates: Free methane found and controversy over the 'hydrate gun''' led to stories in Nature on-line and BBC radio, among others. There were six (6) oral and fifteen (15) poster presentations on ODP Leg 204 hydrate science at the EGS/AGU/EUG Meeting in Nice, France on April 6-11, 2003. This was a very strong showing at a meeting just over six month following the completion of the drilling cruise and highlighted many of the results of the leg, including the results obtained with instruments and equipment funded under this cooperative agreement. At the AAPG annual meeting in Salt Lake City, UT on May 11-14, 2003, Anne Trehu gave an oral presentation about the scientific results of Leg 204, and Frank Rack presented a poster outlining the operational and technical accomplishments. Work continued on analyzing data collected during ODP Leg 204 and preparing reports on the outcomes of Phase 1 projects as well as developing plans for Phase 2.

    The primary accomplishments of the JOI Cooperative Agreement with DOE/NETL in this quarter were that: (1) Leg 204 scientific party members presented preliminary results and operational outcomes of ODP Leg 204 at the American Geophysical Union Fall meeting, which was held in San Francisco, CA; and, (2) a report was prepared by Dr. Gilles Guerin and David Goldberg from Lamont-Doherty Earth Observatory of Columbia University on their postcruise evaluation of the data, tools and measurement systems that were used for vertical seismic profiling (VSP) experiments during ODP Leg 204. The VSP report is provided herein. Intermediate in scale and resolution between the borehole data and the 3-D seismic surveys, the Vertical Seismic Profiles (VSP) carried during Leg 204 were aimed at defining the gas hydrate distribution on hydrate ridge, and refining the signature of gas hydrate in the seismic data. VSP surveys were attempted at five sites, following completion of the conventional logging operations. Bad hole conditions and operational difficulties did not allow to record any data in hole 1245E, but vertical and constant offset VSP were successful in holes 1244E, 1247B and 1250F, and walk-away VSP were successfully completed in holes 1244E, 1250F and 1251H. Three different tools were used for these surveys. The vertical VSP provided the opportunity to calculate interval velocity that could be compared and validated with the sonic logs in the same wells. The interval velocity profiles in Holes 1244E and 1247B are in very good agreement with the sonic logs. Information about the Leg 204 presentations at the AGU meeting are included in a separate Topical Report, which has been provided to DOE/NETL in addition to this Quarterly Report. Work continued on analyzing data collected during ODP Leg 204 and preparing reports on the outcomes of Phase 1 projects as well as developing plans for Phase 2.

    The primary accomplishments of the JOI Cooperative Agreement with DOE/NETL in this quarter were the implementation of a scientific ocean drilling expedition to study marine methane hydrates along the Cascadia margin, in the NE Pacific as part of Integrated Ocean Drilling Program (IODP) Expedition 311 using the R/V JOIDES Resolution and the deployment of all required equipment and personnel to provide the required services during this expedition. IODP Expedition 311 shipboard activities on the JOIDES Resolution began on August 28 and were concluded on October 28, 2005. New ODP Pressure Coring System (PCS) aluminum autoclave chambers were fabricated prior to the expedition. During the expedition, 16 PCS autoclaves containing pressure cores were X-rayed before and after depressurization using a modified Geotek MSCL-P (multi-sensor core logger-pressure) system. These PCS cores were density scanned using the MSCL-V (multi-sensor core logger-vertical) during depressurization to monitor gas evolution. The MSCL-V was set up in a 20-foot-long refrigerated container provided by Texas A&M University through the JOI contract with TAMRF. IODP Expedition 311 was the first time that PCS cores were examined before (using X-ray), during (using MSCL-V gamma density) and after (using X-ray) degassing to determine the actual volume and distribution of sediment and gas hydrate in the pressurized core, which will be important for more accurate determination of mass balances between sediment, gas, gas hydrate, and fluids in the samples collected. Geotek, Ltd was awarded a contract by JOI to provide equipment and personnel to perform pressure coring and related work on IODP Expedition 311 (Cascadia Margin Gas Hydrates). Geotek, Ltd. provided an automated track for use with JOI's infrared camera systems. Four auxiliary monitors showed infrared core images in real time to aid hydrate identification and sampling. Images were collected from 185 cores during the expedition and processed to provide continuous core temperature data. The HYACINTH pressure coring tools, subsystems, and core logging systems were mobilized to Astoria, Oregon. Both HYACINTH pressure coring tools, the HRC (HYACE Rotary Corer) and the FPC (Fugro Pressure Corer) were mobilized and used during the expedition. Two HYACINTH engineers supervised the use of the tools and five good pressure cores were obtained. Velocity, density and X-ray linear scanning data were collected from these cores at near in situ pressure using the MSCL-P system. Dr. Barry Freifeld from Lawrence Berkeley National Laboratory provided an X-ray source and detector for X-ray imaging of pressure cores and helped Geotek with the design and mobilization of the MSCL-P system. Pressure core handling, transfer, and logging was performed in a refrigerated 20-foot container supplied by Geotek, Ltd. After scanning, the pressure cores were stored for on-shore analysis in aluminum barrels. Additional studies were conducted at the Pacific Geoscience Center (PGC), where a shore based laboratory was established after Expedition 311.

    The primary accomplishments of the JOI Cooperative Agreement with DOE/NETL in this quarter were that: (1) follow-up logging of pressure cores containing hydrate-bearing sediment; and (2) opening of some of these cores to establish ground-truth understanding. The follow-up measurements made on pressure cores in storage are part of a hydrate geriatric study related to ODP Leg 204. These activities are described in detail in Appendices A and B of this report. Work also continued on developing plans for Phase 2 of this cooperative agreement based on evolving plans to schedule a scientific ocean drilling expedition to study marine methane hydrates along the Cascadia margin, in the NE Pacific as part of the Integrated Ocean Drilling Program (IODP) using the R/V JOIDES Resolution.

    The primary activities accomplished during this quarter were continued efforts to develop plans for Phase 2 of this cooperative agreement based on the evolving operational planning for IODP Expedition 311, which will use the JOIDES Resolution to study marine methane hydrates along the Cascadia margin, offshore Vancouver Island. IODP Expedition 311 has been designed to further constrain the models for the formation of marine gas hydrate in subduction zone accretionary prisms. The objectives include characterizing the deep origin of the methane, its upward transport, its incorporation in gas hydrate, and its subsequent loss to the seafloor. The main attention of this expedition is on the widespread seafloor-parallel layer of dispersed gas hydrate located just above the base of the predicted stability field. In a gas hydrate formation model, methane is carried upward through regional sediment or small-scale fracture permeability, driven by the tectonic consolidation of the accretionary prism. The upward moving methane is incorporated into the gas hydrate clathrate as it enters the methane hydrate stability zone. Also important is the focusing of a portion of the upward methane flux into localized plumes or channels to form concentrations of near-seafloor gas hydrate. The amount of gas hydrate in local concentrations near the seafloor is especially important for understanding the response of marine gas hydrate to climate change. The expedition includes coring and downhole measurements at five sites across the Northern Cascadia accretionary prism. The sites will track the history of methane in an accretionary prism from (1) its production by mainly microbiological processes over a thick sediment vertical extent, (2) its upward transport through regional or locally focused fluid flow, (3) its incorporation in the regional hydrate layer above the BSR or in local concentrations at or near the seafloor, (4) methane loss from the hydrate by upward diffusion, and (5) methane oxidation and incorporation in seafloor carbonate, or expulsion to the ocean. This expedition builds on the previous Cascadia gas hydrate drilling of ODP Leg 146 and on more recent ODP Leg 204 off Oregon. Important experiments being considered for DOE/NETL funding as part of the JOI cooperative agreement include, (1) Logging-While-Drilling/Measurements-While-Drilling (LWD/MWD), (2) Pressure Core Sampling (PCS/HYACINTH) of gas hydrate, and fluid recovery under in situ conditions, (3) X-ray CT logging of whole cores under in situ conditions, and (4) Infrared thermal imaging of whole round cores to map temperature variations resulting from the presence of hydrate. Preliminary budget estimates have been made for each of these tasks and discussions are ongoing with DOE/NETL program managers to develop a final plan that can be implemented within the constraints of the available funding and logistical considerations.

Finalmente algunas luces de las reflexiones de Kart Barth (§ 5 y de Walter Kasper (§ 6, y la necesidad de una adecuada 'hermenéutica magisterial' (§7. Con esta iluminación, se enfrenta la necesaria complementariedad de los pronunciamientos del Vaticano I y Vaticano II acerca de lo definitivo y lo relativo en el magisterio eclesial (§ 8 y un ejemplo de la Declaración de la Congregación para la Doctrina de la Fe Dominus lesus, sobre la unicidad y la universalidad salvífica de Jesucristo y de la Iglesia (§ 9. Finalmente una recapitulación conclusiva (§ 10. El Magisterio es un servicios, la Iglesia y a la revelación de Dios, que en Cristo se ha automanifestado como plenitud. Siempre deberá ser pensado y ejercitado en una espiritualidad de la comunión eclesial, en una admirable concordia entre fieles y pastores, fruto de la acción del Espíritu. La 'irreformabilidad' de las verdades esenciales en la Iglesia no significa que sean 'irreformulables'. Hay un margen de reformulación que no es irrelevante, aunque esta reformulación no puede tener sentido contrario. Eso significa escuchar devotamente, custodiar celosamente y explicar fielmente lo trasmitido, como lo recordaba el Vaticano II en la constitución sobre la revelación divina. Es un servicio no un dominio, un ministerio no un poder. Y en compañía de todo el pueblo creyente, con el sentido de la fe y otros servicios a la transmisión de la revelación. Se trata de la convicción profunda que Cristo, por la fuerza del Espíritu, sigue vivo y presente en la Iglesia Dios.In order to address the theme of definitive affirmations and the relative in the ecclesial Magisterium, the author will attempt, firstly, to examine the need for a discernment of what pluralism, both absolute and relative, is (1, and then to say a few words about theology and the Magisterium, at the service of the transmission of Christian revelation (2. Afterwards, the theme of the Magisterium as a task of the entire Church will be treated (3, and its understanding (misunderstanding in a globalized world (4. Finally, the author will offer some illuminating thoughts from the reflections of Karl Barth (5 and of Walter Kasper (6 and the necessity of an adequate "Magisterial hermeneutic" (7. With this insight, the necessary complementarity of the pronouncements of Vatican I and Vatican II regarding the definitive and the relative in the ecclesial Magisterium will be explored (8. The author will present an example from the Declaration of the Congregation for the Doctrine of the Faith Domínus lesus, on the unicity and the salvific universality of Jesús Christ and of the Church (9. Finally, the author will formúlate a conclusive summary. (10 The Magisterium is a service to the Church and to the revelation of God, who, in Christ, has manifested Himself as fullness. It must always be a process of thought, and exercised, within a spírituality of ecclesial communion, in an admirable agreement between faithful and pastors, fruit of the action of the Spirit. The "irreformability" of the essential truths in the Church does not mean that they are "unreformable". There is a margin of reformulation that is not irrelevant, although this reformulation cannot have a contrary sense. That means listeníng devoutedly, guarding scrupulously, and explaining faithfully what is transmitted, as Vatican reminds us in the Constitution on Divine Revelation. It is a service rather than a dominión, a ministryaná not a power, conducted in company with the whole believing people, with the sense of faith and other services in the transmission of revelation. In short, the author will be examining nothing less that the profound conviction that Christ, by the strength of the Spirit, continúes to live and be present in the Church of God.

    A novel anionic waterborne polyurethane-based fluorescent dye WPU-DV26 was synthesized by incorporating the molecular structure of disperse violet 26 (DV26) into the polyurethane chain. The structure of WPU-DV26 was confirmed by means of Fourier transform infrared spectroscopy and UV–vis absorption analysis. Comparing to the UV–vis spectrum of DV26, WPU-DV26 showed a hypsochromic shift from the absorption maxima of 518, 558, 609 nm to 510, 548, 586 nm, respectively. WPU-DV26 can form stable latex in water. The number average molecular weight and its distribution index, and average latex particle size for WPU-DV26 were determined to be 2.33×10{sup 4}, 1.36 and 80 nm, respectively. The improved thermal stability of WPU-DV26 can be attributed to the embedded anthraquinone unit of DV26. It was found that both the intensity and stability of the fluorescence of WPU-DV26 latex were improved significantly compared with those of DV26. -- Highlights: ► A waterborne polyurethane-based polymeric dye was synthesized. ► The fluorescence intensity of WPU-DV26 emulsion was enhanced greatly compared with that of DV26. ► The fluorescence stability of WPU-DV26 emulsion was fine not only for long term storage but also for fluorescence quencher.

    2015-07-01

    Full Text Available Dengue virus (DV infection is the most prevalent mosquito-borne viral disease and its manifestation has been shown to be contributed in part by the host immune responses. In this study, pathogen recognition receptors, Toll-like receptor (TLR 2 and TLR6 were found to be up-regulated in DV-infected human PBMC using immunofluorescence staining, flow cytometry and Western blot analyses. Using ELISA, IL-6 and TNF-α, cytokines downstream of TLR2 and TLR6 signaling pathways were also found to be up-regulated in DV-infected PBMC. IL-6 and TNF-α production by PBMC were reduced when TLR2 and TLR6 were blocked using TLR2 and TLR6 neutralizing antibodies during DV infection. These results suggested that signaling pathways of TLR2 and TLR6 were activated during DV infection and its activation contributed to IL-6 and TNF-α production. DV NS1 protein was found to significantly increase the production of IL-6 and TNF-α when added to PBMC. The amount of IL-6 and TNF-α stimulated by DV NS1 protein was reduced when TLR2 and TLR6 were blocked, suggesting that DV NS1 protein is the viral protein responsible for the activation of TLR2 and TLR6 during DV infection. Secreted alkaline phosphatase (SEAP reporter assay was used to further confirm activation of TLR2 and TLR6 by DV NS1 protein. In addition, DV-infected and DV NS1 protein-treated TLR6-/- mice have higher survivability compared to DV-infected and DV NS1 protein-treated wild-type mice. Hence, activation of TLR6 via DV NS1 protein could potentially play an important role in the immunopathogenesis of DV infection.

    Domestic violence (DV) is a major public problem affecting 30% of women over 16. Three quarters of victims have violence to the head and neck, and therefore the role of the dentist is paramount in DV identification. Only one-third of dental schools in the UK include DV in their curricula and there is a need to introduce effective education for the…

    Research is lacking on differing perspectives regarding custody cases involving domestic violence (DV). In a survey of judges, legal aid attorneys, private attorneys, DV program workers, and child custody evaluators (n = 1,187), judges, private attorneys, and evaluators were more likely to believe that mothers make false DV allegations and alienate their children. In response to a vignette, evaluators and private attorneys were most likely to recommend joint custody and least likely to recommend sole custody to the survivor. Legal aid attorneys and DV workers were similar on many variables. Gender, DV knowledge, and knowing victims explained many group differences.

    2013-01-01

    We interviewed 12 Jordanian women who had experienced domestic violence (DV) and were receiving assistance at the Jordanian Women's Union (JWU). Our aim was to explore the history and factors supporting attainment of freedom from DV. Narratives revealed themes of DV toward girls; forced marriage; physical, psychological, or sexual abuse before and during marriage; and escalation and enduring DV. Escaping from DV required family and JWU support. In the context of a strongly patriarchal, religious society, we observed a process of resolution by shifting cultural values and themes of empowerment, with an undercurrent of suffering blamed on inequalities in the legal process.

    This study examined the associations of exposure to spousal violence in the family and personal and peer attitudes with dating violence (DV) perpetration among high school students in Port-au-Prince, Haiti. Participants were 342 high school students in Grades 10 to 12 who stated that they had ever been on a date. Multiple linear regression methods were used to examine correlates of the scale of DV perpetration. Findings showed that personal acceptance of DV mediated the association between exposure to wife-perpetrated and husband-perpetrated spousal violence in the family and DV perpetration for girls. Boys who were exposed to husband-perpetrated spousal violence in the family had significantly higher levels of psychological DV perpetration than those who were not. Contrary to expectations, exposure to wife-perpetrated spousal violence in the family was negatively associated with psychological and physical/sexual DV perpetration by boys, after controlling for other factors. Overall, perceived peer tolerance of DV was more strongly associated with DV perpetration than personal tolerance of DV, and was the only significant correlate of psychological DV perpetration for girls. Perceived peer attitudes also moderated the association between boys' exposure to spousal violence in the family and DV perpetration. Implications for future research and policy are discussed.

    For the purification plant Koerkwitz (Baltic Sea area, Germany) an autonomous hybrid power supply system was developed and installed using the regenerative energy sources sun and wind. The realized energy management is furthermore prepared for the additional installation of a bio-gas plant. For the final realization stage of self-supporting portion of more than 80% is expected. Surplus energy is fed to the public grid. Main components of the installed plant are a 250 kWp solar generator and a 300 kW wind converter. For the energy conversion three in parallel connected inverters are installed in a master/slave mode. An efficiency optimization is obtained by Maximum-Power-Point controlling and automatic switching on and off under partial load operation. The whole process control is performed by an energy management system which consists of a command caculator, central compact programmable controllers and local data acquisition devices for subsystems. The plant was started up in September, 1993 and is operating since that time without problems. (orig.)

    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.

    To examine whether combining the dichotomous assessment of the a-wave and the ductus venosus (DV) pulsatility index for veins (PIV) measurement improves first-trimester screening performance. Retrospective study performed at the University Hospital of Tuebingen based on singleton pregnancies that underwent first-trimester screening including DV flow assessment. In each case, the risk of trisomy 21 was calculated based on maternal age, fetal nuchal translucency, and DV flow either as dichotomous classification of the a-wave, as measurement of the DV PIV, or both. There were 5280 euploid fetuses and 127 fetuses with trisomy 21. The DV a-wave was reversed in 2.3% and 66.1% in the euploid and trisomy 21 cases, respectively. The DV PIV measurements were above the 95th percentile in 8.3% and 77.2% the euploid and trisomy 21 cases, respectively. For a false positive rate of 3%, the detection rate for trisomy 21 based on maternal age, fetal NT, and DV flow is about 87% irrespective of whether DV is examined as a continuous or dichotomous variable. The combination of both resulted in a small decrease at 3% false positive rate. Assessment of the DV a-wave and the DV PIV result in similar DRs. Combining these two approaches does not appear to improve their individual screening performance. © 2017 John Wiley & Sons, Ltd. © 2017 John Wiley & Sons, Ltd.

    Full Text Available Introduction: Pregnancy in adolescents and domestic violence (DV are worldwide problems. Their prevalence is influenced by cultural factors. Objectives: To characterize pregnant adolescents and their sexual partners, and to determine the prevalence of psychological, physical and sexual DV. Methodology: Cross-sectional study of 406 Colombian pregnant teenagers. Socio-demographic data were collected, and the scales “Are you being abused?” and “Abuse Assessment Screen” were applied. The former identifies domestic violence by the partner, and the latter, DV at any moment, the last year or during pregnancy. Results: Age: 16.5 ± 1.5 years, 92.9 % were in late adolescence, average years of schooling: nine; 50 % dropped out from school when they became pregnant; 70 % depended on their parents, both before and after pregnancy. DV by the partner: 7.1 %; physical DV: 6.7 %; psychological DV: 3.7 %; sexual DV: 2.2 %. DV by partner/husband/other person: 12.4 %; physical or emotional abuse by partner/another person: 21.7 %; fear from the partner: 3.4 %. There was significant association between alcohol consumption by the partner every weekend and DV. Conclusion: Frequency of DV against pregnant adolescents is high and alcohol consumption by the partner is an important risk factor for it.

    We estimated the diameters below which 50% and 90% of the volume of droplets exist (Dv50 and Dv90, respectively) of 1 oil-based (Permanone 30-30) and 2 water-based (AquaReslin, Aqua-K-Othrine) antievaporant aerosols (with the Film Forming Aqueous Spray Technology [FFAST]) using Teflon- and magnesium oxide (MgO)-coated slides and determined whether the aging of the droplets on the slides (up to 60 min) exhibited any significant effect on Dv50 and Dv90 calculations. There were no significant differences in either Dv50 or Dv90 estimates on MgO-coated slides at 0 min and 60 min for all 3 products tested. On Teflon-coated slides, the only product that showed significant difference between 0 min and 60 min in both Dv50 and Dv90 estimates was Aqua-K-Othrine, perhaps due to a difference in formulation components. Specifically, both values corresponding to Dv50 and Dv90 at 60 min decreased by approximately 50% when compared to the values at 0 min. For the other 2 products, AquaReslin and Permanone, aging of droplets on Teflon up to 60 min did not have any significant effect on Dv50 and Dv90 values. To further investigate the behavior of Aqua-K-Othrine droplets on Teflon-coated slides we observed the droplets immediately after spraying and at 10-min intervals under different conditions of temperature and humidity. The majority of the shrinkage occurred within the 1st 10 min after impaction on the slides under all conditions tested. So in most field situations where slides are read several hours or days after collection, this shrinkage would not be observed. The MgO-coated slides should be the preferred field method for sampling droplets of Aqua-K-Othirne with the FFAST antievaporant technology.

    Domestic violence (DV) is reported by 40% of married women in India and associated with substantial morbidity. An operational research definition is therefore needed to enhance understanding of DV epidemiology in India and inform DV interventions and measures. To arrive at a culturally-tailored definition, we aimed to better understand how definitions provided by the World Health Organization and the 2005 India Protection of Women from Domestic Violence Act match the perceptions of behaviors constituting DV among the Indian community. Between September 2012 and January 2013, 16 key informant interviews with experts in DV and family counseling and 2 gender-concordant focus groups of lay community members were conducted in Pune, India to understand community perceptions of the definition of DV, perpetrators of DV, and examples of DV encountered by married women in Pune, India. Several key themes emerged regarding behaviors and acts constituting DV including 1) the exertion of control over a woman’s reproductive decision-making, mobility, socializing with family and friends, finances, and access to food and nutrition, 2) the widespread acceptance of sexual abuse and the influences of affluence on sexual DV manifestations, 3) the shaping of physical abuse experiences by readily-available tools and the presence of witnesses, 4) psychological abuse for infertility, dowry, and girl-children, and 5) the perpetration of DV by the husband and other members of his family. Findings support the need for a culturally-tailored operational definition that expands on the WHO surveillance definition to inform the development of more effective DV intervention strategies and measures.

    2015-01-01

    The establishment of dorsoventral (DV) axis in the Drosophila embryo relies on the Toll/Dorsal signaling pathway. The transcription factor Dorsal acts downstream of Toll forming a nuclear gradient that determines different cell fates along the DV axis. The formation of the DV axis has been studied in two other holometabolous insects, the bee- tle Tribolium and the wasp Nasonia. However, the role of Toll signaling has not been addressed in the more basally branching hemimetabolous insects. Her...

    Nanoparticulate delivery systems for vaccine adjuvants, designed to enhance targeting of secondary lymphoid organs and activation of APCs, have shown substantial promise for enhanced immunopotentiation. We investigated the adjuvant activity of synthetic oligonucleotides containing CpG-rich motifs linked to the sucrose polymer Ficoll, forming soluble 50-nm particles (DV230-Ficoll), each containing >100 molecules of the TLR9 ligand, DV230. DV230-Ficoll was evaluated as an adjuvant for a candidate vaccine for anthrax using recombinant protective Ag (rPA) from Bacillus anthracis. A single immunization with rPA plus DV230-Ficoll induced 10-fold higher titers of toxin-neutralizing Abs in cynomolgus monkeys at 2 wk compared with animals immunized with equivalent amounts of monomeric DV230. Monkeys immunized either once or twice with rPA plus DV230-Ficoll were completely protected from challenge with 200 LD50 aerosolized anthrax spores. In mice, DV230-Ficoll was more potent than DV230 for the induction of innate immune responses at the injection site and draining lymph nodes. DV230-Ficoll was preferentially colocalized with rPA in key APC populations and induced greater maturation marker expression (CD69 and CD86) on these cells and stronger germinal center B and T cell responses, relative to DV230. DV230-Ficoll was also preferentially retained at the injection site and draining lymph nodes and produced fewer systemic inflammatory responses. These findings support the development of DV230-Ficoll as an adjuvant platform, particularly for vaccines such as for anthrax, for which rapid induction of protective immunity and memory with a single injection is very important.

    This qualitative study explores whether individuals working within the domestic violence (DV) field in the United States have utilized a human rights framework and identifies potential benefits of this framework. Using the critique and experiences of women of color as a focal point, data were gathered through interviews with key individuals working with national and regional DV and human rights organizations. This article focuses on challenges within the mainstream DV movement and how a human rights approach could potentially ameliorate some of these concerns by supporting a more holistic approach to DV and increasing coalition building and community engagement.

    Domestic violence (DV) is prevalent among women in India and has been associated with poor mental and physical health. We performed a systematic review of 137 quantitative studies published in the prior decade that directly evaluated the DV experiences of Indian women to summarise the breadth of recent work and identify gaps in the literature. Among studies surveying at least two forms of abuse, a median 41% of women reported experiencing DV during their lifetime and 30% in the past year. We noted substantial inter-study variance in DV prevalence estimates, attributable in part to different study populations and settings, but also to a lack of standardisation, validation, and cultural adaptation of DV survey instruments. There was paucity of studies evaluating the DV experiences of women over age 50, residing in live-in relationships, same-sex relationships, tribal villages, and of women from the northern regions of India. Additionally, our review highlighted a gap in research evaluating the impact of DV on physical health. We conclude with a research agenda calling for additional qualitative and longitudinal quantitative studies to explore the DV correlates proposed by this quantitative literature to inform the development of a culturally tailored DV scale and prevention strategies.

    Reciprocal signalling and gene expression play a cardinal role during pathogen-host molecular interactions and are prerequisite to the maintenance of balanced homeostasis. Gene expression repertoire changes during rickettsial infection and glutathione-S-transferases (GSTs) were among the genes found up-regulated in Rickettsia-infected Dermacentor variabilis. GSTs are well known to play an important part in cellular stress responses in the host. We have cloned two full-length GSTs from D. variabilis (DvGST1 and DvGST2). Comparison of these two DvGST molecules with those of other species indicate that DvGST1 is related to the mammalian class theta and insect class delta GSTs, while DvGST2 does not seem to fall in the same family. Northern blotting analyses revealed differential expression patterns, where DvGST1 and DvGST2 transcripts are found in the tick gut, with DvGST2 transcripts also present in the ovaries. Both DvGST transcripts are up-regulated upon tick feeding. Challenge of fed adult ticks with Escherichia coli injection showed decreased transcript amounts compared with ticks injected with phosphate-buffered saline (sham) and naïve ticks.

    Full Text Available Ductus venosus (DV has a pivotal role in the fetal circulation. It serves as a conduit connecting the fetal umbilical and portal venous system with the inferior vena cava (IVC. The absence of DV is an uncommon anomaly. In case of agenesis of DV, the umbilical vein joins the fetal systemic venous circulation via the intra-hepatic or extra-hepatic route. We report a case of absent DV with associated anomaly diagnosed in the first trimester using three-dimensional (3D colour Doppler.

  6. Human apolipoprotein A-I is associated with dengue virus and enhances virus infection through SR-BI.

    Directory of Open Access Journals (Sweden)

    Yujia Li

    Full Text Available Diseases caused by dengue virus (DV infection vary in severity, with symptoms ranging from mild fever to life threatening dengue hemorrhage fever (DHF and dengue shock syndrome (DSS. Clinical studies have shown that significant decrease in the level of lipoproteins is correlated with severe illness in DHF/DSS patients. Available evidence also indicates that lipoproteins including high-density lipoprotein (HDL and low-density lipoprotein (LDL are able to facilitate cell entry of HCV or other flaviviruses via corresponding lipoprotein receptors. In this study, we found that pre-incubation of DV with human serum leads to an enhanced DV infectivity in various types of cells. Such enhancement could be due to interactions between serum components and DV particles. Through co-immunoprecipitation we revealed that apolipoprotein A-I (ApoA-I, the major protein component in HDL, is associated with DV particles and is able to promote DV infection. Based on that observation, we further found that siRNA knockdown of the scavenger receptor class B type I (SR-BI, the cell receptor of ApoA-I, abolished the activity of ApoA-I in enhancement of DV infection. This suggests that ApoA-I bridges DV particles and cell receptor SR-BI and facilitates entry of DV into cells. FACS analysis of cell surface dengue antigen after virus absorption further confirmed that ApoA-I enhances DV infection via promoting initial attachment of the virus to cells. These findings illustrate a novel entry route of DV into cells, which may provide insights into the functional importance of lipoproteins in dengue pathogenesis.

    The yellowing strain of Soybean dwarf virus (SbDV-YS) causes yellowing and yield loss in common bean (Phaseolus vulgaris). The most effective control is achieved through breeding for resistance. An indeterminate climbing cultivar with a white seed coat, 'Oofuku', is resistant to SbDV-YS in inoculation tests. We crossed 'Oofuku' with an elite cultivar, 'Taisho-Kintoki', which is SbDV-YS-susceptible, determinate dwarf with a red-purple seed coat, and performed amplified-fragment-length polymorphism analysis of F3 lines. From nucleotide sequences of the resistant-specific fragments and their flanking regions, we developed five DNA markers, of which DV86, DV386, and DV398 were closely linked to Sdvy-1, a resistance gene. Using the markers, we developed 'Toiku-B79' and 'Toiku-B80', the near-isogenic lines (NILs) incorporating Sdvy-1 in the background of 'Taisho-Kintoki'. The NILs had similar growth habit, maturity date and seed shape to those of 'Taisho-Kintoki'. The quality of boiled beans was also similar, except that the NILs had more seed coat cracking than 'Taisho-Kintoki'. The NILs showed no SbDV-YS infection in inoculation tests. We suggest that Sdvy-1 is a useful source of SbDV-YS resistance in common bean.

    Physicians have been called on to identify victims of domestic violence (DV) and sexual abuse (SA). Few data exist, however, on the prevalence of DV and SA in physicians themselves or on the personal or professional sequelae of such experiences. We determined the reported lifetime prevalence of DV and SA among women physicians and the personal characteristics, health-related factors, and work-related factors associated with these forms of abuse. We used data from the Women Physicians' Health Study, a large (n = 4501 respondents), nationally distributed questionnaire study that included questions on DV and SA histories, personal characteristics, and psychiatric, medical, and work-related histories. We compared the characteristics of women physicians with and without histories of DV or SA. The logistic models indicate that women physicians reporting DV histories (3.7% of the population) were significantly (p suicide attempts, substance abuse, current or past cigarette smoking, severe daily stress at home, chronic fatigue syndrome, and DV experienced by their mothers. Women physicians reporting SA histories (4.7% of the population) were significantly more likely to be younger than 60 years, identify themselves as homosexual or bisexual, to have specialized in psychiatry, obstetrics and gynecology, or emergency medicine, and to report histories of depression, suicide attempts, eating disorders, and fair or poor perceived health status. Although the reported lifetime prevalence of DV and SA among women physicians is below other reported figures, such experiences are associated with medical and psychiatric difficulties that could negatively affect them personally and professionally.

    2015-05-01

    To examine the impact that domestic violence (DV) has on hindering the success of urban migrants in Peru and any association with maternal depression, impaired parenting, social capital, and child development. This was a cross-sectional study consisting of structured interviews with 97 mothers and their school-aged children in El Porvenir, a predominantly migrant area of the city of Trujillo, Peru. Data collection occurred in February-June 2011. Proven tools previously validated for use in Spanish were used to assess the following variables: maternal depression, social capital, domestic violence, parenting behaviors, child socioemotional development, and child cognitive development. Correlational, multiple regression, tests of interaction, and indirect/mediator models were used for analysis. Sixty-five percent of women reported currently experiencing DV. DV strongly predicted depression (P social capital (P < 0.01), engaged in fewer caregiving activities (P < 0.05), had less maternal energy (P < 0.05), and were less warm (P < 0.05). DV was associated with internalizing behaviors in children (P < 0.01), with impaired parenting partially mediating this relationship. DV compromises women's mental health and parenting ability. High rates of DV among urban migrants affect the whole community by hindering employment potential and reducing trust among community members. Interventions targeting DV-related variables (e.g., substance abuse and limited job opportunities for men) could reduce the deleterious effects of DV on urban migrant communities across Latin America.

    Yang, Shaobin; Li, Sinan; Tang, Shuwei; Shen, Ding; Dong, Wei; Sun, Wen

    2017-04-01

    The interaction between inserted/adsorbed Na and the structures of pristine and defective bilayer graphene (BLG) with Stone-Wales (SW), mono-vacancy (MV) and divacancy (DV) defects have been investigated by the first-principles calculations. The computational results show that the intercalation of Na in the interlayer of BLG with DV defects is more energetically favorable than Na adsorption on the surface. The lower formation energies of Na adsorption/intercalation on/in the BLG with DV defect reflect a stronger attraction between Na and DV defects compared with MV and SW defects. A significant charge transfer occurs from Na to near graphene layer(s) of BLG. The adsorption and intercalation of Na not only induce more significant structural distortion into the upper layer graphene with SW defect but also spin polarization for MV and DV defects. The results of migration energy barriers show that Na prefers to diffuse toward the DV site, and the diffusion outward the DV site is more difficult in comparison with the SW and MV defects. As a consequence, more Na atoms would be trapped in the region of the DV defect, leading to larger capacity than SW and MV defects.

    The purpose of this study was to compare the domestic violence (DV) rate identified with simple direct questioning to a historical cohort of patients receiving routine emergency department (ED) care. One thousand ED charts of female patients were retrospectively reviewed. Each patient in the prospective cohort was asked five DV specific questions. The historical cohort revealed a DV prevalence rate of 0.4%. The prospective study group of 302 patients identified 11 (3.6%) patients who admitted to acute DV on direct questioning. Ten of these patients accepted help. Twenty (6.6%) were identified as probable DV and 12 (4%) admitted to past violence. The total number of victims of DV, past, present, and probable was 43 (14.2%). This increase in detection from 0.4% (4/1000) to 14.2% (43/302) is significant at p patients refused to participate in the DV specific questions. The conclusion of the study indicated that the use of simple, direct questioning significantly improves the detection rate of DV in the ED.

    2015-09-01

    Dengue virus (DV) infection demonstrates an intriguing virus-induced intracellular membrane alteration that results in the augmentation of major histocompatibility complex (MHC) class I-restricted antigen presentation. As oppose to its biological function in attracting CD8(+) T-cells, this phenomenon appears to facilitate the immune evasion. However, the molecular events that attribute to the dysregulation of the antigen presenting mechanism (APM) by DV remain obscure. In this study, we aimed to characterize the host cell APM upon infection with all serotypes of whole DV. Cellular RNA were isolated from infected cells and the gene expressions of LMP2, LMP7, TAP1, TAP2, TAPBP, CALR, CANX, PDIA3, HLA-A and HLA-B were analyzed via quantitative PCR. The profiles of the gene expression were further validated. We showed that all four DV serotypes modulate host APM at the proteasomal level with DV2 showing the most prominent expression profile.

  13. Custody evaluators' beliefs about domestic violence allegations during divorce: feminist and family violence perspectives.

    2011-05-01

    Approximately, 20% of divorcing couples in the United States require judicial intervention to reach a custody agreement. In such cases, courts often call on child custody evaluators to conduct comprehensive evaluations and recommend custody agreements and services that meet children's best interests. Estimates suggest that allegations of domestic violence (DV) are raised and substantiated in about 75% of these cases. Custody evaluators are thus in a position to ensure that divorcing parents with DV receive effective services and enter into safe custody agreements. They are also in a position to minimize or deny the seriousness of DV and its relevance to custody decisions. The present study uses grounded theory methods to examine how custody evaluators' theoretical perspectives on DV and beliefs about custody disputes in the context of DV are related to their evaluation process and recommendations.

    2012-01-01

    Following the success of the audio video standard (AVS) for 2D video coding, in 2008, the China AVS workgroup started developing 3D video (3DV) coding techniques. In this paper, we discuss the background, technical features, and applications of AVS 3DV coding technology. We introduce two core techniques used in AVS 3DV coding: inter-view prediction and enhanced stereo packing coding. We elaborate on these techniques, which are used in the AVS real-time 3DV encoder. An application of the AVS 3DV coding system is presented to show the great practical value of this system. Simulation results show that the advanced techniques used in AVS 3DV coding provide remarkable coding gain compared with techniques used in a simulcast scheme.

  15. Expression patterns indicate that BMP2/4 and Chordin, not BMP5-8 and Gremlin, mediate dorsal-ventral patterning in the mollusk Crassostrea gigas.

    Science.gov (United States)

    Tan, Sujian; Huan, Pin; Liu, Baozhong

    2016-12-16

    Though several bilaterian animals use a conserved BMP2/4-Chordin antagonism to pattern the dorsal-ventral (DV) axis, the only lophotrochozoan species in which early DV patterning has been studied to date, the leech Helobdella robusta, appears to employ BMP5-8 and Gremlin. These findings call into question the conservation of a common DV patterning mechanism among bilaterian animals. To explore whether the unusual DV patterning mechanism in H. robusta is also used in other lophotrochozoan species, we investigated the expression of orthologous genes in the early embryo of a bivalve mollusk, Crassostrea gigas. Searching of the genome and phylogenetic analysis revealed that C. gigas possesses single orthologs of BMP2/4, Chordin, and BMP5-8 and no Gremlin homolog. Whole mount in situ hybridization revealed mRNA localization of BMP2/4 and Chordin on the opposite sides of embryos, suggesting the potential involvement of a BMP2/4-Chordin antagonism in DV patterning in this species. Furthermore, universal BMP5-8 expression and the absence of a Gremlin homolog in the C. gigas genome called into question any major contribution by BMP5-8 and Gremlin to early DV patterning in this species. Additionally, we identified seven genes showing asymmetric expression along the DV axis, providing further insight into DV patterning in C. gigas. We present the first report of a Chordin gene in a lophotrochozoan species and of the opposite expression of BMP2/4 (dorsal) and Chordin (ventral) along the D/V axis of a lophotrochozoan embryo. The findings of this study further the knowledge of axis formation in lophotrochozoan species and provide insight into the evolution of the animal DV patterning mechanism.

  16. A method to identify early ventricular dysfunction using resting gated blood pool scans (GBPS) in patients with coronary artery disease (CAD)

    1984-01-01

    To determine the sensitivity of regional 1st and 2nd time derivative (1DV, 2DV) images to assess ventricular function (VF) in CAD, the resting GBPS of 8 normal patients (pts) and 20 pts with CAD who had coronary angiography and contrast ventriculography (CV) were analyzed. The 1DV and 2DV of the systolic time-activity curve were determined for each left ventricular pixel in the GBPS. These values were displayed as functional images that were reviewed by three readers to determine the presence of regional abnormalities. No regional abnormalities were seen in the conventional GBPS or 1DV or 2DV images of the 8 normal pts. Regional GBPS and DV image abnormalities were seen in all 10 pts with CAD and abnormal wall motion by CV. The DV image abnormalities were in the distribution of 18/22 coronary arteries (CA) with greater than or equal to50% stenoses; 2 of these regions showed normal wall motion by CV and conventional GBPS. DV images were abnormal in 2/8 CAs without significant stenoses. In addition, regional DV image abnormalities were present in 9 of 10 pts with CAD who had normal wall motion and global ejection fraction by both CV and resting GBPS. These 10 pts showed regional abnormalities in the distribution of 13/15 CAs with significant stenoses and 2/15 CAs without such stenoses. The results suggest that time derivative functional images derived from resting GBPS provide a more sensitive means for detecting regional left ventricular dysfunction than several other current methods, especially in pts with mild CAD.

    2013-05-01

    We have performed first-principles calculations to study the chemical functionalization of the BN graphene with divacancy (DV) defect by 12 different transition metal (TM) atoms, including Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Pt, and Au. The results indicate that the DV defect can assist the adsorption of TM atoms on BN graphene. Moreover, some impurity bands are induced within the band gap of DV-BN graphene, leading to the modification of its electronic properties in various ways. Interestingly, Ti- and Co-adsorbed DV-BN graphenes are found to possess ferromagnetic characteristic, while antiferromagnetic state is preferred for V-, Mn-, and Fe-functionalized DV-BN graphenes, and the paramagnetic state is the ground state for Sc-, Cr-, Ni-, Cu, Zn-, Pt-, and Au-decorated DV-BN graphenes. Finally, aiming at evaluating the potential of these functionalized BN graphenes in hydrogen storage, we study their interaction with H2 molecules. It is found that the dispersed Sc, V, and Cr on DV-BN graphene are able to adsorb up to three H2 molecules as strongly as 0.25-0.58 eV/H2, suggesting that the three nanomaterials may be suitable candidates for hydrogen storage.

    Parents' childhood experiences of trauma may influence their reports of their children's behavior, and this may be particularly true when children are also traumatized. The present study proposed and tested a matched trauma hypothesis, positing that compared to parents without a childhood history of witnessing domestic violence (DV), parents with a childhood history of witnessing DV may report their children's trauma-related symptomatology differently following children's exposure to DV. Of 137 included parents (M age = 32 years; 93% mothers), 81 reported witnessing childhood DV (matched group), whereas 56 reported no childhood DV exposure (nonmatched comparison group). All parents reported on their 3- to 6-year-old children's dissociation and posttraumatic stress symptoms following children's DV exposure. An analysis of covariance controlling for parental life stress, dissociation symptoms, and other childhood traumatic events revealed that parents who witnessed childhood DV reported significantly fewer child dissociation symptoms than comparison parents. No difference was found for parents' reports of children's posttraumatic stress symptoms. Exploratory analyses on a subsample of children with teacher reports of child dissociation symptoms (n = 75) revealed that the strength of the association between parent and teacher reports of dissociation symptoms was moderated by matched versus nonmatched group membership. Findings suggest the importance of considering a parent's history of trauma when using parents as informants for children's trauma symptoms.

    We have performed first-principles calculations to study the chemical functionalization of the BN graphene with divacancy (DV) defect by 12 different transition metal (TM) atoms, including Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Pt, and Au. The results indicate that the DV defect can assist the adsorption of TM atoms on BN graphene. Moreover, some impurity bands are induced within the band gap of DV-BN graphene, leading to the modification of its electronic properties in various ways. Interestingly, Ti- and Co-adsorbed DV-BN graphenes are found to possess ferromagnetic characteristic, while antiferromagnetic state is preferred for V-, Mn-, and Fe-functionalized DV-BN graphenes, and the paramagnetic state is the ground state for Sc-, Cr-, Ni-, Cu, Zn-, Pt-, and Au-decorated DV-BN graphenes. Finally, aiming at evaluating the potential of these functionalized BN graphenes in hydrogen storage, we study their interaction with H{sub 2} molecules. It is found that the dispersed Sc, V, and Cr on DV-BN graphene are able to adsorb up to three H{sub 2} molecules as strongly as 0.25–0.58 eV/H{sub 2}, suggesting that the three nanomaterials may be suitable candidates for hydrogen storage.

    Full Text Available Background: In India, women are not keen to seek formal help to solve the issue of domestic violence (DV. Aim and objectives: Current study attempted to understand the profile of women who sought or availed institutional help (legal/counselling services etc. to address DV. Material and methods: Data were collected from sixty women aged between 18 years and 50 who faced domestic violence from their husbands. Results: Most of the respondents were young, unemployed and not well educated. They faced physical, emotional & verbal, sexual and economic types of violence from husbands and husbands’ family members. Their children also witnessed DV. Perceived causes for DV were; husbands’ exposure on their parental violence, psychoactive substance abuse, dissatisfied sexual life, extra marital relationships in husbands and influence of other wife-beating family members. Most of them felt that DV as their fate and had attempted suicide. Even though many of them received legal help; many felt that, legal help was not adequate in addressing DV. Conclusion: Importance of mental health approach to address DV has been discussed.

    Despite the occurrence of encouraging political and social changes in the past few years, many beliefs about women's role in intimate relationships persist, influencing their response to domestic violence (DV). This study aims to analyze the influence of recent policies against DV in Portugal, concerning particularly intimate partner violence against women and their perceptions about the victimization process. Two samples of women (n = 126 each) reporting an aggressive act allegedly perpetrated by the current or former male partner were interviewed with a hiatus of 5 years (before and after some most relevant policy updates). Results suggest a positive influence of the recent policies against DV. Many significant and encouraging changes were found in the more recent women sample (S2) relatively to the first sample (S1) regarding their information, awareness, perceptions, and attitudes toward DV. They seem to show less tolerance and endurance to DV, placing responsibility on the offender, as well as seem more empowered to report. In S2, there was a decrease in the acceptance of violent behaviors as normal and of reasons to explain violence; the fears, shame, and helplessness about DV; the elapsed time between the beginning of the abuse and its report; and the prevalence of more severe types of physical abuse. In S2, there was an increase on the acknowledgment of DV as a crime, the number of reports in cases without cohabitation, the report of psychological abuses, and the feeling of safety and assurance while reporting.

    Populations of at least 20 asteroid species on the Northeast Pacific Coast have recently experienced an extensive outbreak of sea-star (asteroid) wasting disease (SSWD). The disease leads to behavioral changes, lesions, loss of turgor, limb autotomy, and death characterized by rapid degradation ("melting"). Here, we present evidence from experimental challenge studies and field observations that link the mass mortalities to a densovirus (Parvoviridae). Virus-sized material (i.e., <0.2 μm) from symptomatic tissues that was inoculated into asymptomatic asteroids consistently resulted in SSWD signs whereas animals receiving heat-killed (i.e., control) virus-sized inoculum remained asymptomatic. Viral metagenomic investigations revealed the sea star-associated densovirus (SSaDV) as the most likely candidate virus associated with tissues from symptomatic asteroids. Quantification of SSaDV during transmission trials indicated that progression of SSWD paralleled increased SSaDV load. In field surveys, SSaDV loads were more abundant in symptomatic than in asymptomatic asteroids. SSaDV could be detected in plankton, sediments and in nonasteroid echinoderms, providing a possible mechanism for viral spread. SSaDV was detected in museum specimens of asteroids from 1942, suggesting that it has been present on the North American Pacific Coast for at least 72 y. SSaDV is therefore the most promising candidate disease agent responsible for asteroid mass mortality.

    Cytogenetic and DNA molecular analyses have been carried out in 3 wheat introgression lines (ILs; CS×V58, CS×V59, and CS×V60) derived from Triticum aestivum cv. 'Chinese Spring' (CS) × Dasypyrum villosum(Dv) intergeneric hybridization. All lines, which showed several phenotypic differences compared to CS, had the same chromosome number (2n = 42) and structure as CS, and neither chromosomes nor chromatin from Dv were apparently added to their complement. However, Feulgen/DNA cytophotometry showed that there was more nuclear DNA in the lines than in the parental wheat (by 1.85%, 2.76%, and 1.26% in CS×V58, CS×V59, and CS×V60, respectively). Molecular investigation indicated the presence of Dv DNA in the ILs. AFLP analysis of genomic DNA from the ILs, CS, and Dv detected a total of 120 polymorphic bands, of which 7 (5.8%) were present in some or all the ILs and Dv but were absent in CS. PCR amplification, sequence analysis of amplicons, and Southern blot hybridization confirmed the presence of Dv-specific sequences in each of the ILs. These results indicate cryptic introgression of Dv DNA sequences into the genome of the ILs. Some implications of this finding are discussed. Copyright © 2011 S. Karger AG, Basel.

    To assess the value of ductus venosus pulsatility index for veins (DV PIV) in screening for aneuploidies at 11-13 weeks' gestation. Fetal DV PIV was measured in singleton pregnancies undergoing first-trimester screening for aneuploidies. In euploid (n = 44,756) and aneuploid (202 cases of trisomy 21, 72 cases of trisomy 18 and 30 cases of trisomy 13) fetuses, DV PIV was best described by a mixture model of distributions. Performance of screening for aneuploidies by DV PIV alone and in combination with fetal nuchal translucency (NT) thickness and serum free β-hCG and PAPP-A was estimated. In euploid pregnancies there was a bimodal distribution of DV PIV with a dominant crown-rump length (CRL)-dependent part, accounting for around 97% of cases in Caucasians and around 93% in Afro-Caribbeans, and a smaller CRL-independent distribution. In aneuploidies the dominant part was the CRL-independent distribution, which accounted for around 85% cases of trisomies 21 and 18 and 70% of cases of trisomy 13. In screening for trisomy 21 by maternal age, NT and biochemistry at a risk cutoff of 1 in 100, the detection rate was 89.7% and false positive rate was 2.74%; with addition of DV PIV, the values were 93.5 and 1.63%, respectively. Measurement of DV PIV improves the performance of first-trimester combined test for aneuploidies. Copyright © 2012 S. Karger AG, Basel.

    Data virtualization (DV) refers to a set of data stores that enable users to query, access, and manipulate data in a unified, abstracted, and encapsulated manner regardless of data location. Apart from reducing data movement, this system provides a unified, abstracted, real-time, and encapsulated view of information for query purposes. Through its provision of live, virtual data in a timely manner, the DV technique can overcome the obstacles faced by organizations and companies as a result of using other data integration techniques. The systematic planning for the period that precedes DV deployment enables organizations to avoid many challenges related to manageability, usability, data quality, and performance. DV requirements are among the most significant and challenging aspects of a DV project. In this study, an approach has been developed to gather and manage the requirements of a DV design model as an initial step in developing such projects. Expert methods are reviewed to validate and evaluate the proposed approach in terms of usability and related components; the results of this review demonstrate that the applied approaches benefit DV development projects.

  6. Pathogenesis of malaria revisited.

    2012-11-01

    Plasmodium falciparum malaria claims 1 million lives around the globe every year. Parasitemia can reach remarkably high levels. The developing parasite digests hemoglobin and converts the waste product to hemozoin alias malaria pigment. These processes occur in a vesicular compartment named the digestive vacuole (DV). Each parasitized cell releases one DV upon rupture. Myriads of DVs thus gain entry into the blood, but whether they trigger pathobiological events has never been investigated. We recently discovered that the DV membrane simultaneously activates the two major enzyme cascades in blood, complement and coagulation. Activation of both is known to occur in patients with severe malaria, so discovery of the common trigger has large consequences. The DV membrane but not the merozoite has the capacity to spontaneously activate the alternative complement and intrinsic clotting pathway. Ejection of merozoites and the DV into the bloodstream, therefore, results in selective opsonization and phagocytosis of the DV, leaving merozoites free to invade new cells. The DV membrane furthermore has the capacity to assemble prothrombinase, the key convertase of the intrinsic clotting pathway. The dual capacity of the DV to activate both complement and coagulation can be suppressed by low-molecular-weight dextran sulfate. This agent protects experimental animals from the detrimental consequences, resulting from intravenous application of purified DVs. Phagocytosis of DVs not only deploys PMN away from merozoites, but also drives the cells into a state of functional exhaustion. This may be one reason for the enhanced susceptibility of patients with severe malaria toward systemic bacterial infections. Together, these findings indicate that the DV may represent a hitherto unrecognized, important determinant of parasite pathogenicity.

  7. DEPOSITION VELOCITY ESTIMATION WITH THE GENII V2 SOFTWARE

    In 2010, the Department of Energy (DOE) Chief of Nuclear Safety and Office of Health, Safety and Security (HSS), with the support of industry experts in atmospheric sciences and accident dose consequences analysis, performed detailed analyses of the basis for the dry deposition velocity (DV) values used in the MACCS2 computer code. As a result of these analyses, DOE concluded that the historically used default DV values of 1 centimeter/second (cm/s) for unfiltered/unmitigated releases and 0.1 cm/s for filtered/mitigated releases may not be reasonably conservative for all DOE sites and accident scenarios. HSS recently issued Safety Bulletin 2011-02, Accident Analysis Parameter Update, recommending the use of the newly developed default DV, 0.1 cm/s for an unmitigated/unfiltered release. Alternatively site specific DV values can be developed using GENII version 2 (GENII v2) computer code. Key input parameters for calculating DV values include surface roughness, maximum wind speed for calm, particle size, particle density and meteorological data (wind speed and stability class). This paper will include reasonably conservative inputs, and a truncated parametric study. In lieu of the highly-conservative recommended DV value (0.1cm/s) for unmitigated/unfiltered release, GENII v2 has been used to justify estimated 95th percentile DV values. Also presented here are atmospheric dilution factors ({chi}/Q values) calculated with the MACCS2 code using the DV values form GENII v2, {chi}/Q values calculated directly with GENII v2, and a discussion of these results compare with one another. This paper will give an overview of the process of calculating DV with GENII v2 including a discussion of the sensitivity of input parameters.

    Dengue is one of the most important mosquito-borne viral diseases. In past years, although considerable effort has been put into the development of a vaccine, there is currently no licensed dengue vaccine. In this study, we constructed DNA vaccines that carried the prM-E-NS1 genes of dengue virus serotype 1 (DV1) with or without the granulocyte-macrophage colony-stimulating factor (GM-CSF) gene, an attractive DNA vaccine adjuvant. Immunization with the plasmid pCAG-DV1/E/NS1, which expresses viral prM-E-NS1, or the bicistronic plasmid pCAG-DV1-GM, which co-expresses viral prM-E-NS1 and GM-CSF, resulted in long-term IgG response, high levels of splenocyte-secreted interferon-γ and interleukin-2, strong cytotoxic T lymphocyte activity and sufficient protection in the DV1-challenged mice. This suggested that both humoral and cellular immune responses were induced by the immunizations and that they played important roles in protection against the DV1 challenge. Interestingly, the magnitude, quality and protective capacity of the immune responses induced by immunization with pCAG-DV1/E/NS1 or pCAG-DV1-GM seemed stronger than those induced by pCAG-DV1/E (expressing viral prM-E alone). Taken together, we demonstrated that prM/E plus NS1 would be a suitable solution for the development of a DNA vaccine against DV.

  9. RIG-I, MDA5 and TLR3 synergistically play an important role in restriction of dengue virus infection.

    Directory of Open Access Journals (Sweden)

    A M A Nasirudeen

    Full Text Available Dengue virus (DV infection is one of the most common mosquito-borne viral diseases in the world. The innate immune system is important for the early detection of virus and for mounting a cascade of defense measures which include the production of type 1 interferon (IFN. Hence, a thorough understanding of the innate immune response during DV infection would be essential for our understanding of the DV pathogenesis. A recent application of the microarray to dengue virus type 1 (DV1 infected lung carcinoma cells revealed the increased expression of both extracellular and cytoplasmic pattern recognition receptors; retinoic acid inducible gene-I (RIG-I, melanoma differentiation associated gene-5 (MDA-5 and Toll-like receptor-3 (TLR3. These intracellular RNA sensors were previously reported to sense DV infection in different cells. In this study, we show that they are collectively involved in initiating an effective IFN production against DV. Cells silenced for these genes were highly susceptible to DV infection. RIG-I and MDA5 knockdown HUH-7 cells and TLR3 knockout macrophages were highly susceptible to DV infection. When cells were silenced for only RIG-I and MDA5 (but not TLR3, substantial production of IFN-β was observed upon virus infection and vice versa. High susceptibility to virus infection led to ER-stress induced apoptosis in HUH-7 cells. Collectively, our studies demonstrate that the intracellular RNA virus sensors (RIG-I, MDA5 and TLR3 are activated upon DV infection and are essential for host defense against the virus.

  10. zen and the art of phenotypic maintenance: canalization of embryonic dorsal-ventral patterning in Drosophila.

    Gavin-Smyth, Jackie; Ferguson, Edwin L

    2014-01-01

    We recently uncovered a novel genetic mechanism that generates the phenotypic uniformity, or canalization, of BMP signaling and cell fate specification during patterning of the dorsal-ventral (D/V) axis in D. melanogaster embryos. We went on to show that other wild-type Drosophila species lack this canalizing genetic circuitry and, consequently, have non-robust D/V patterning. In this review, we propose molecular mechanisms that may give rise to stereotyped BMP signaling, and we identify an additional species that could have decanalized D/V patterning. Extension of these analyses could in turn help explain why canalization is not a universal necessity for species survival.

    2013-07-01

    In this study, domestic violence (DV) in five African refugee background communities post-settlement in Perth, Australia, is investigated-specifically, the interrelationship between experiences of DV, and changed and changing gender and family roles and responsibilities. The participatory qualitative design utilized in-depth interviews with 54 members of the Somalian, Sierra Leonean, Ethiopian, Liberian and Sudanese Communities, and focus groups with 24 professionals who support them. Three key dimensions of this interrelationship are discussed: "male loss of the breadwinner role and status," "financial independence," and "mismatch between formal response and expectations." The importance of understanding experiences of DV within the context of cultural transition is highlighted here.

    The aim of this study was to assess the relationship between the intra-cyclic variation of the horizontal velocity (dv) and the velocity of the 4 competitive swimming techniques in young swimmers. 45 young swimmers performed a set of maximal 4 × 25 m (freestyle, backstroke, breaststroke and butterfly stroke) swims with in water start. A speed-meter cable was attached to the swimmer's hip. The dv and the swimming velocity were analyzed. Within-subject tests presented significant variations in the dv based on the swimming technique. Post-hoc test revealed significant differences across all pair-wised swimming techniques (Pswimming velocity in all swimming techniques (0.24 ≤ R(2) ≤ 0.51). As a conclusion, there is a non-linear relationship where the increase of swimming velocity leads to a decrease of dv in young competitive swimmers. © Georg Thieme Verlag KG Stuttgart · New York.

    Schacht, Rebecca L; Dimidjian, Sona; George, William H; Berns, Sara B

    2009-01-01

    Guidelines for addressing domestic violence (DV) in couple therapy have been published, but reports of whether therapists routinely follow these suggestions are few. A national survey of 620 couple therapists randomly selected from American Association for Marriage and Family Therapy members was conducted in 2000 to assess therapists' strategies for assessing DV and selecting a treatment modality when violence is discovered. Less than 4% of respondents indicated consistently following key published guidelines for DV screening (universal screening using separate interviews and questionnaires). A minority indicated that they consider the victim's safety as a factor in treatment modality selection. DV may be under-identified by couple therapists and therapists may be using conjoint therapy with couples for whom such therapy is contraindicated because of relationship violence.

    An in situ forming hydrogel obtained by crosslinking of amino functionalized hyaluronic acid derivatives with divinylsulfone functionalized inulin (INU-DV) has been here designed and characterized. In particular two hyaluronic acid derivatives bearing respectively a pendant ethylenediamino (EDA) portion (HA-EDA) and both EDA and octadecyl pendant groups (HA-EDA-C18) were crosslinked through an azo-Michael reaction with INU-DV. Gelation time and consumption of DV portions have been evaluated on hydrogel obtained using HA-EDA and HA-EDA-C18 derivatives with a concentration of 3% w/v and a ratio 80/20 w/w respect to the crosslinker INU-DV. The presence of pendant C18 chains improves mechanical performances of hydrogels and decreases the susceptibility to hyaluronidase hydrolysis. Bovine chondrocytes, encapsulated during crosslinking, sufficiently survive and efficiently proliferate until 28 days of analysis.

    2017-01-01

    Dating violence (DV) is now recognized as an important public health issue. Prevention and intervention programs are being implemented in school contexts. Such initiatives aim to raise awareness among potential victims and offenders as well as among peer bystanders and offer adequate interventions following disclosure. Yet, a major challenge remains as teenagers may not disclose their victimization or may not feel self-efficient to deal with DV if they witness such violence. As such, teen DV remains largely hidden. A representative sample of 8 194 students (age 14–18) in the province of Quebec, Canada was used to explore teenagers’ self-efficacy to reach out for help or to help others in a situation of DV victimization and perpetration. Analyses are conducted to identify possible correlates of self-efficacy in terms of socio-demographic variable (sex, age) and a history of child sexual abuse and dating victimization. Implications for prevention and support strategies are discussed.

    For improving the localisation accuracy of range-free node algorithm, we introduce a kind of improved algorithm which is based on quantum genetic algorithm (QGA) aiming at the DV-Hop algorithm. Using the estimated distance between nodes and the position of anchor nodes, in third stage of DV-Hop algorithm the QGA is employed to correct the estimated position derived from DV-Hop. The binary-quantum-coding, quantum rotate gate and mutation algorithm are used to update the individuals. Simulation results show that the improved algorithm is stable in performance and can get global optimal solution, and makes the obvious decrease in location error of DV-Hop.%为了提高非测距节点定位算法的定位精度,针对DV-Hop算法提出一种基于量子遗传算法的改进算法.利用节点间的估计距离和锚节点的位置,在DV-Hop算法的第三阶段采用量子遗传算法校正DV-Hop得到的估算位置,采用二进制量子编码和量子旋转门以及变异处理更新个体.仿真结果表明,改进的算法性能稳定,能找到全局最优解,并使DV-Hop的定位误差明显下降.

    The disturbance vicariance hypothesis (DV) has been proposed to explain speciation in Amazonia, especially its edge regions, e. g. in eastern Guiana Shield harlequin frogs (Atelopus) which are suggested to have derived from a cool-adapted Andean ancestor. In concordance with DV predictions we studied that (i) these amphibians display a natural distribution gap in central Amazonia; (ii) east of this gap they constitute a monophyletic lineage which is nested within a pre-Andean/western clade; (...

  13. Displacement ventilation and passive cooling strategies

    Energy Technology Data Exchange (ETDEWEB)

    Carew, P.; Bekker, B. [PJCarew Consulting, Cape Town (South Africa)

    2009-07-01

    Displacement ventilation (DV) is widely used a passive cooling strategy because it requires less air supply for cooling compared to conventional mixing ventilation (MV). DV introduces air at low level and low velocity, and at high supply air temperature, usually around 18 degrees C. The slightly cooler air runs along the floor of a room until it reaches a heat load. The heat load induces a plume of warmer air that rises due to lower density. This induces stratification in room temperature with the occupied area of the room. The air near the ceiling is continually exhausted to prevent a build up of warm air into the occupied zone. This paper demonstrated the impacts of using DV in comparison to MV on the peak capacity, size and humidity levels associated with various passive cooling strategies, informed by the ASHRAE DV guidelines. A generic office building in Johannesburg, South Africa, was used as a model. The paper illustrated the extent to which DV can be used as a passive cooling strategy in spaces that were previously considered as having too high a heat load when calculated using MV system guidelines. A comparison of DV and MV also highlighted the risk of over-design when conventional MV guidelines are used to design cooling sources for DV applications. The DV was shown to significantly lower the amount of supply air needed to serve a room's heat load when compared to MV at the same temperatures. This reduction in air supply impacts the feasibility of using passive cooling strategies in evaporative cooling, 2-stage evaporative cooling, thermal storage and air to ground heat exchangers. However, passive cooling strategies are unlikely to be widely implemented until design guidelines are created by organizations such as ASHRAE. 8 refs., 2 tabs., 15 figs.

    Domestic violence (DV) has significant health impacts for victims and their families. Despite evidence that routine screening increases the identification of DV and opportunities for support; routine screening is uncommon in Australian emergency departments (EDs). This study explored ED clinicians' level of support for DV screening; current screening practices; and perceived barriers and readiness to screen prior to a pilot intervention. Census survey of 76 ED clinicians. A number of questionnaire items were generated through a review of the literature, with readiness to screen for DV assessed through the short version of the Domestic Violence Healthcare Provider Scale [1]. The confidential and anonymous online survey was hosted on the Qualtrics platform. Descriptive and comparative statistical analysis was performed using IBM SPSS version 22. Most clinicians supported screening for DV in the ED. In the absence of protocols, 72.3% (n=55) of clinicians reported currently engaging in case-based screening, which preferenced women with physical injury. The majority did not always feel comfortable screening for DV (79.7% n=59) and reported they had received insufficient training for this role (88.7% n=55). Lower perceived self-efficacy and fear of offending were statistically associated with discomfort or negative beliefs about DV enquiry (p=<0.05). Emergency department clinicians reported feeling ill-equipped and under-prepared to inquire about and respond to DV. These findings provide valuable insight about the training and support needs of ED clinicians prior to the commencement of routine screening in EDs. Copyright © 2017. Published by Elsevier Ltd.

    Background Domestic violence (DV) is not only a devastating societal problem, but also a severe medical and mental health problem worldwide. Our previous study has shown that perpetrators were with higher prevalence of self-reported symptoms than that of controls. This study based on our former large scale population-based samples is aimed to further explore the correlations between the symptoms and psychosocial factors of the perpetrators with DV. It was helpful to provide some insight into possible strategies for clinicians to reduce the symptoms of the perpetrators with DV in China.Methods From our former population-based epidemiological samples, 1098 households with a history of DV in preceding year, 318 perpetrators with DV were randomly selected. Face-to-face interviews were conducted. Symptom Checklist-90 (SCL-90) was administrated to check and classify the symptoms of perpetrators, Eysenck's personality questionnaire(EPQ), trait coping style questionnaire (TCSQ), life events scale (LES) and social supporting rating scale (SSRS) were administrated to evaluate the psychosocial factors of perpetrators. The correlation analysis was used to analyze the relationships between the symptoms and psychosocial factors of perpetrators of DV. Results The global and all subscale scores of SCL-90 were significantly positively correlated with EPQ-N, negative TCSQ and negative LES scores (P<0.01). The global score of SCL-90 was negatively correlated with both objective and subjective SSRS (P<0.01). The negative LES and negative TCSQ were significantly positively correlated with EPQ-N (P <0.01). Negative TCSQ was significantly positively correlated with negative LES and negatively correlated with subjective SSRS (P<0.01).Conclusions The self-reported symptoms of perpetrators with DV were strongly correlated with their psychosocial factors, such as the neurotic personality, negative coping style, more negative life events and less subjective social supports.

    2012-03-01

    This article reviews research, policy and programming in Australia, Canada and the US on the child welfare response to EDV. The review draws on searches of standard research databases, interviews with researchers and practitioners, and the authors' own research. Although EDV is underreported, across studies 7% to 23% of youths in general population surveys experienced EDV, 36-39% of youth in DV cases have witnessed the violence, and 45-46% of primary caregivers in child maltreatment investigations have experienced DV. Mandatory reporting can increase the number of cases that come to the attention of child welfare, but without resources for training and programming can lead to inappropriate reports, lack of referral for further assessment, and strains on the child welfare system. Improving the child welfare response to EDV can include collaboration between child welfare workers and DV advocates; increased training on screening for DV; new protocols on DV; and dedicated DV staffing within child welfare agencies. In recent years, policy and program attention to EDV has also been embedded within broader national efforts to protect children from violence and maltreatment. Differential response models that eschew investigation in favor of assessment and service delivery hold promise for families with DV. Empirical data are limited, but current research and practice experience suggest that child welfare agencies seeking to improve the response to EDV should collaborate with other disciplines involved with preventing and responding to DV, seek resources to support training and programming, consider methods that avoid stigmatizing parents, and build in a program evaluation component to increase knowledge about effective practice.

    In this paper, we propose a new localization algorithm and improve the DV-Hop algorithm by using a differential error correction scheme that is designed to reduce the location error accumulated over multiple hops. This scheme needs no additional hardware support and can be implemented in a distributed way. The proposed method can improve location accuracy without increasing communication traffic and computing complexity. Simulation results show the performance of the proposed algorithm is superior to that of the DV-Hop algorithm.

    Full Text Available Integration and display of results from multiple neuroimaging modalities (e.g. MRI, MEG, EEG relies on display of a diverse range of data within a common, defined coordinate frame. DataViewer3D (DV3D is a multi-modal imaging data visualization tool offering a cross-platform, open-source solution to simultaneous data overlay visualization requirements of imaging studies. While DV3D is primarily a visualization tool, the package allows an analysis approach where results from one imaging modality can guide comparative analysis of another modality in a single coordinate space. DV3D is built on Python, a dynamic object-oriented programming language with support for integration of modular toolkits, and development of cross-platform software for neuroimaging. DV3D harnesses the power of the Visualization Toolkit (VTK for 2D and 3D rendering, calling VTK's low level C++ functions from Python. Users interact with data via an intuitive interface that uses Python to bind wxWidgets, which in turn calls the user's operating system dialogs and graphical user interface tools. DV3D currently supports NIfTI-1, ANALYZE™ and DICOM formats for MRI data display (including statistical data overlay. Formats for other data types are supported. The modularity of DV3D and ease of use of Python allows rapid integration of additonal format support and user development. DV3D has been tested on Mac OSX, RedHat Linux and Microsoft Windows XP. DV3D is offered for free download with an extensive set of tutorial resources and example data.

  6. Authentication of digital video evidence

    In response to a requirement from the United States Postal Inspection Service, the Technical Support Working Group tasked The Johns Hopkins University Applied Physics Laboratory (JHU/APL) to develop a technique tha will ensure the authenticity, or integrity, of digital video (DV). Verifiable integrity is needed if DV evidence is to withstand a challenge to its admissibility in court on the grounds that it can be easily edited. Specifically, the verification technique must detect additions, deletions, or modifications to DV and satisfy the two-part criteria pertaining to scientific evidence as articulated in Daubert et al. v. Merrell Dow Pharmaceuticals Inc., 43 F3d (9th Circuit, 1995). JHU/APL has developed a prototype digital video authenticator (DVA) that generates digital signatures based on public key cryptography at the frame level of the DV. Signature generation and recording is accomplished at the same time as DV is recorded by the camcorder. Throughput supports the consumer-grade camcorder data rate of 25 Mbps. The DVA software is implemented on a commercial laptop computer, which is connected to a commercial digital camcorder via the IEEE-1394 serial interface. A security token provides agent identification and the interface to the public key infrastructure (PKI) that is needed for management of the public keys central to DV integrity verification.

    This cross-sectional study was performed to determine (1) whether female victims of domestic violence (DV) are more likely to use the 911 system than nonvictims (NVs) and (2) whether DV and NVs call 911 for different reasons so that 911 may be used as a screening tool for abuse. The study was performed in an academic adult urban emergency department (ED). Ambulatory female patients presenting to the ED were studied. Eligible patients were administered a brief survey by trained research assistants. Questions included (1) history of DV, (2) relationship of assailant to victim, (3) chief complaint, and (4) use of the 911 system. Records of 911 calls were obtained by patient's address. Four hundred sixty-one women were enrolled in the study. One hundred seven (23%) reported a history of DV. Intimate partners accounted for 67.2% of assailants. DV victims were more likely to be single and younger (P domestic dispute (1.4 v0.5 calls, P = .007; 11.7 v6.1 calls, P = .0003). Victims and nonvictims did not differ in the number of nondomestic dispute calls (8.4 v6.2 calls; P = .15). DV victims were more likely to access the 911 system and call for domestic disturbances compared with nonvictims. 911 calls may serve as an indicator of ongoing abuse and may identify women at risk, providing a potential opportunity for intervention.

    To assess patient ratings of comfort alone and in front of children with 5 domestic violence (DV) screening questions designed with less graphic language compared with questions about other sensitive issues. A sample of mothers (n = 200), including a small sample of Spanish-speaking women, were recruited from community locations. Mothers rated their perceptions of comfort for answering 13 sensitive issue screening questions (including sexual risk, substance abuse, depression, and DV questions). Logistic regression was performed to analyze participants' characteristics with respect to summary comfort scores. In addition, 40 mothers were asked to talk about their comfort in answering the DV questions. These interviews were audiotaped and analyzed. Mothers preferred to answer all questions alone. Comfort with answering the DV screening questions in front of their children was higher than comfort with sexual risk or depression questions and was similar to comfort with substance abuse questions. Latina mothers had more discomfort with the DV questions than other ethnicities. Although mothers were more comfortable with answering sensitive questions alone than in the presence of children, this may not be feasible in busy offices. General DV questions may be appropriate to ask in front of children as an initial screen.

    High vein density (D(V)) evolution in angiosperms represented a key functional transition. Yet, a mechanistic account on how this hydraulic transformation evolved remains lacking. We demonstrate that a consequence of producing high D(V is that veins must become very small to fit inside the leaf, and that angiosperms are the only clade that evolved the specific type of vessel required to yield sufficiently conductive miniature leaf veins. From 111 species spanning key divergences in vascular plant evolution, we show, using analyses of vein conduit evolution in relation to vein packing, that a key xylem innovation associated with high D(V) evolution is a strong reduction in vein thickness and simplification of the perforation plates of primary xylem vessels. Simple perforation plates in the leaf xylem occurred only in derived angiosperm clades exhibiting high D(V) (> 12 mm mm(-2)). Perforation plates in the vessels of other species, including extant basal angiosperms, consisted of resistive scalariform types that were associated with thicker veins and much lower D(V). We conclude that a reduction in within-vein conduit resistance allowed vein size to decrease. We suggest that this adaptation may have been a critical evolutionary step that enabled dramatic D(V) elaboration in angiosperms.

    Background Greater neck strength and activating the neck muscles to brace for impact are both thought to reduce an athlete's risk of concussion during a collision by attenuating the head's kinematic response after impact. However, the literature reporting the neck's role in controlling postimpact head kinematics is mixed. Furthermore, these relationships have not been examined in the coronal or transverse planes or in pediatric athletes. Hypotheses In each anatomic plane, peak linear velocity (DV) and peak angular velocity (Dv) of the head are inversely related to maximal isometric cervical muscle strength in the opposing direction (H1). Under impulsive loading, DV and Dv will be decreased during anticipatory cervical muscle activation compared with the baseline state (H2). Study Design Descriptive laboratory study. Methods Maximum isometric neck strength was measured in each anatomic plane in 46 male and female contact sport athletes aged 8 to 30 years. A loading apparatus applied impulsive test forces to athletes' heads in flexion, extension, lateral flexion, and axial rotation during baseline and anticipatory cervical muscle activation conditions. Multivariate linear mixed models were used to determine the effects of neck strength and cervical muscle activation on head DV and Dv. Results Greater isometric neck strength and anticipatory activation were independently associated with decreased head DV and Dv after impulsive loading across all planes of motion (all P\\.001). Inverse relationships between neck strength and head DV and Dv presented moderately strong effect sizes (r = 0.417 to r = 0.657), varying by direction of motion and cervical muscle activation. Conclusion In male and female athletes across the age spectrum, greater neck strength and anticipatory cervical muscle activation (“bracing for impact”) can reduce the magnitude of the head's kinematic response. Future studies should determine whether neck strength contributes to the observed sex and

  14. The Rise of Flowering Plants and Land Surface Physics: The Cretaceous and Eocene Were Different

    The Cretaceous and Eocene have served as the poster children of past greenhouse climates. One difference between the two time periods is that angiosperms (flowering plants) underwent a major diversification and rise to dominance during the mid-Cretaceous to Paleocene. Flowering plants differ from all other living and fossil plants in having significantly higher rates of transpiration and photosynthesis, which in modern leaves correlate with the density of venation (Dv), a feature that can be measured directly from fossils. This increase in Dv, coupled with an increase in the abundance of angiosperms, is thought to have had major impact on the climate system. This is, in part, because transpiration plays an important role in determining the ratio of sensible to latent heat flux from the land surface and in determining precipitation rate in regions such as the equatorial rainforest. Analysis of Dv in fossil leaves indicates two phases of increase in transpiration rate for angiosperms during the Cretaceous-Paleocene. The oldest known angiosperms (Aptian-early Albian) have a low Dv characteristic of extant and fossil ferns and gymnosperms. At this time angiosperms are low-stature plants of minor importance in terms of relative abundance and diversity (<5%). The first phase of Dv increase occurs during the Late Albian to Cenomanian, where average Dv is 40% greater than that of conifers and ferns, and maximum Dv reaches levels characteristic of many trees from the temperate zone. This first phase coincides with the first local dominance of angiosperms, the first occurrence of moderate to large angiosperm trees (up to 1 m in diameter) , and the first common occurrence of angiosperms in the Arctic. The second phase of Dv increase occurs during the Maastrichtian to Paleocene, where average Dv reaches levels characteristic of modern tropical forests and maximum Dv reaches the level found in highly productive modern vegetation. This second phase coincides with the rise to

    Dating violence (DV) has emerged as a major concern among youth with links to substance use, injuries, and death. The emergency department (ED) provides an opportunity for violence screening and prevention interventions. Additional data are needed regarding antecedents of DV versus non-dating violence (NDV; e.g., acquaintance, stranger) to develop ED-based violence interventions for youth. Participants were 575 patients screening positive for past 6-month drug use in an urban ED who completed timeline follow-back aggression modules at baseline and 6- and 12-months, indicating event-specific antecedents of violence. Multi-level logistic regressions using event-level data, nested by individual and time (i.e. baseline, 6- and 12-month assessment intervals), were used to examine antecedents of DV vs. NDV. Post-hoc analyses examined substance use×reasons and gender interactions. Prescription sedative/opioid misuse was more likely to be reported prior to DV whereas alcohol only, and co-ingested alcohol and marijuana only, were more likely to be reported prior to NDV. Reasons for DV included: "personal belongings", "angry/bad mood," "jealousy," "drunk/high on drugs" and "arguing about sex". Reasons for NDV included: "rumors," "retaliation," "personal space" and "aid (someone) due to physical attack". Substance use before/during conflicts and reasons for conflicts were both uniquely associated with DV versus NDV. Two gender interactions were found. ED based interventions for urban youth need to be tailored by gender, substance use (alcohol, cocaine, sedatives), reasons for violence, and type of violence (DV vs. NDV). © 2013.

    Domestic violence (DV) is a serious risk for women's health. So far, little attention has been paid to this area in research and medical care in Germany. Acknowledging this deficit, the S.I.G.N.A.L.-Intervention Project has started to develop a program to improve the medical care for victimized women. For the first time in Germany, data on the health care needs of victimized women have been collected within the S.I.G.N.A.L.-Evaluation Research Project. This article presents the results of a female patient survey (n=806) on DV conducted in the emergency department (ED) of a university hospital in Berlin. The results demonstrate that 36.6% of women reported at least one episode of DV after the age of 16. A total of 4.6% were victims of DV over the past year, and 1.5% of women came to the ED for treatment of injuries caused by violence. A total of 57% of the victims of at least one episode of DV in their lifetime after the age of 16 described a negative impact on their health. The most frequently reported sequelae were head injuries, haematomas and fractures, gastrointestinal disorders, headache/migraine and heart disease. The psychological symptoms were anxiety, depression and suicide/self-mutilation attempts. Some 52% of the victims who reported health consequences had received medical care. In case of DV occurring, 67% of all women said that they would discuss it with their physicians. Approximately 80% of all respondents favoured a routine inquiry for DV as part of the medical history protocol of the ED.

    Domestic violence (DV) and other experienced trauma types increase the risk for impaired functioning. Access to social resources may provide a buffer to existing risks and allow individuals to continue and build functioning. This cross-sectional study investigated the direct effects of DV and access to social resources (perceived social support, social integration, and frequency of social contact), as well as their potential interactive effects, on daily functioning among 894 male and female trauma survivors who attended primary care clinics in Kurdistan, Iraq in 2009 and 2010. Experiencing DV was not associated with functioning for males (p=.15) or females (p=.60), suggesting that in the context of a trauma-affected sample, the experience of DV may not significantly increase the risk for functional impairment. Greater amounts of social integration were associated with less functional impairment among males (p<.01) and females (p<.05); social integration was associated with less functional impairment among males only (p<.01); and frequency of social contact was associated with less functional impairment among females only (p<.05), indicating that the association between social resource type and functioning differed by gender. Social resources had a stronger effect on functioning among men compared to women. Among males who experienced DV, social integration was the only social resource associated with less functional impairment (p<.01); among male trauma survivors who did not experience DV, social support was the only resource associated with less functional impairment (p<.01). Further investigation into these associations is warranted to inform intervention strategies for survivors of DV and other traumas in post-conflict settings.

    Five year (2010-2014) Advanced Very High Resolution Radiometer (AVHRR) sea surface temperature (SST) data produced by the Australian Bureau of Meteorology have been validated against drifting buoy data and then used to study the seasonal patterns of the SST diurnal variation (DV) events over the Tropical Warm Pool region (TWP, 25°S-15°N, 90°E-170°E). The in situ validation results illustrate the overall good quality of the AVHRR SST data set, although an average 0.19 K underestimation of the daytime measurements has been observed. The nighttime observations are in good agreement with in situ buoys with an average bias of 0.03 and a 0.30 K standard deviation of the biases. This SST data set is then used to characterize the SST DV seasonal patterns, together with wind speeds, daily maximum solar shortwave insolation (SSImax), and latent heat flux (LHF). A double-peak seasonal pattern of SST DV is observed over the study region: the strongest DVs are found in March and October and the weakest in June. Sensitivity tests of DV to wind, SSImax, and LHF are conducted. The results indicate (1) different morning and early afternoon winds (7 A.M. to 2 P.M. local time, LT) affect DV by as much as 0.73 K when the half-daily (defined as 2 A.M. to 2 P.M. LT in this study) average winds are fixed between 2 and 3 m s-1; (2) SSImax levels regulate DV less significantly (<0.68 K) under fixed winds; and (3) LHF effects on DV are relatively weak (<0.35 K).

  19. Structural covariance mapping delineates medial and medio-lateral temporal networks in déjà vu.

    Déjà vu (DV) is an eerie phenomenon experienced frequently as an aura of temporal lobe epilepsy, but also reported commonly by healthy individuals. The former pathological manifestation appears to result from aberrant neural activity among brain structures within the medial temporal lobes. Recent studies also implicate medial temporal brain structures in the non-pathological experience of DV, but as one element of a diffuse neuroanatomical correlate; it remains to be seen if neural activity among the medial temporal lobes also underlies this benign manifestation. The present study set out to investigate this. Due to its unpredictable and infrequent occurrence, however, non-pathological DV does not lend itself easily to functional neuroimaging. Instead, we draw on research showing that brain structure covaries among regions that interact frequently as nodes of functional networks. Specifically, we assessed whether grey-matter covariance among structures implicated in non-pathological DV differs according to the frequency with which the phenomenon is experienced. This revealed two diverging patterns of structural covariation: Among the first, comprised primarily of medial temporal structures and the caudate, grey-matter volume becomes more positively correlated with higher frequency of DV experience. The second pattern encompasses medial and lateral temporal structures, among which greater DV frequency is associated with more negatively correlated grey matter. Using a meta-analytic method of co-activation mapping, we demonstrate a higher probability of functional interactions among brain structures constituting the former pattern, particularly during memory-related processes. Our findings suggest that altered neural signalling within memory-related medial temporal brain structures underlies both pathological and non-pathological DV.

    The control of medically important arthropod vectors of human and animal disease is a high priority for both public health and military officials. Because droplet size of pesticide spray material is a critical factor affecting vector control applications, the droplet-size spectra produced by 11 sprayers and 3 spray formulations were evaluated. Droplet-size spectra were measured by a laser diffraction instrument, a hot-wire system, and rotating slides. There were considerable differences in the droplet-size spectra produced by the different sprayers tested. The volume median diameter (Dv0.5) for the water-based sprays ranged from 4.7 to 211 microm, depending on the sprayer, and the percent of spray volume contained in droplets less than 20 microm (%vol <20 microm) ranged between 0.5% and 98.9%. The Dv0.5 measurements for the oil-based sprays ranged from 9.4 to 125.3 microm and the %vol <20 microm ranged between 2.4% and 97.9%. The correlations between the Dv0.5 measured by the laser system (Dv0.5-laser) and the mass median diameter, Sauter diameter, and Dv0.5 measured by the AIMS probe were all significant. Generally, the slide Dv0.5s were numerically similar to the Dv0.5 from the laser system and the Sauter diameter from the Army Insecticide Measuring System probe. There was less consistent agreement between the % <32 microm values obtained from the slides and those from the other 2 samplers. The information presented can be used by applicators to select the sprayer that produces the droplet-size spectra needed for their particular application situation.

    The physiological and biochemical responses of a drought tolerant, virus-susceptible cowpea genotype exposed to drought stress (D), infected by Cowpea severe mosaic virus (CPSMV) (V), and to these two combined stresses (DV), at 2 and 6 days post viral inoculation (DPI), were evaluated. Gas exchange parameters (net photosynthesis, transpiration rate, stomatal conductance, and internal CO2 partial pressure) were reduced in D and DV at 2 and 6 DPI compared to control plants (C). Photosynthesis was reduced by stomatal and biochemical limitations. Water use efficiency increased at 2 DPI in D, DV, and V, but at 6 DPI only in D and DV compared to C. Photochemical parameters (effective quantum efficiency of photosystem II and electron transport rate) decreased in D and DV compared to C, especially at 6 DPI. The potential quantum efficiency of photosystem II did not change, indicating reversible photoinhibition of photosystem II. In DV, catalase decreased at 2 and 6 DPI, ascorbate peroxidase increased at 2 DPI, but decreased at 6 DPI. Hydrogen peroxide increased at 2 and 6 DPI. Peroxidase increased at 6 DPI and chitinase at 2 and 6 DPI. β-1,3-glucanase decreased in DV at 6 DPI compared to V. Drought increased cowpea susceptibility to CPSMV at 2 DPI, as verified by RT-PCR. However, at 6 DPI, the cowpea plants overcome this effect. Likewise, CPSMV increased the negative effects of drought at 2 DPI, but not at 6 DPI. It was concluded that the responses to combined stresses are not additive and cannot be extrapolated from the study of individual stresses.

    Full Text Available Context: Violence against women is a global phenomenon that cuts across all social and economic classes. Aims:This study was designed to measure the prevalence and correlates of domestic violence (DV among women seeking services at a voluntary counseling and testing (VCT center in Bangalore, India. Settings and Designs: A cross-sectional survey was conducted among women visiting an human immunodeficiency virus (HIV VCT center in Bangalore, between September and November 2005. Materials and Methods:An interviewer-administered questionnaire was used to collect information about violence and other variables. Statistical Analysis Used:Univariable associations with DV were made using Pearson Chi-squared test for categorical variables and Student t-test or the Mann-Whitney test for continuous variables. Results:0 Forty-two percent of respondents reported DV, including physical abuse (29%, psychological abuse (69% and sexual abuse (1%. Among the women who reported violence of any kind, 67% also reported that they were HIV seropositive. The most common reasons reported for DV included financial problems (38%, husband′s alcohol use (29% and woman′s HIV status (18%. Older women (P < 0.001 and those with low income levels were the most likely to have experienced DV (P = 0.02. Other factors included husband′s education, HIV seropositivity and alcohol or tobacco use (P < 0.001. Conclusion: This study found DV levels comparable to other studies from around the world. The findings highlight the need for additional training among health care providers in VCT centers in screening for DV, detection of signs of physical abuse and provisions and referrals for women suffering from domestic partner violence.

    Domestic violence (DV) against women is a serious human rights abuse and well recognised global public health concern. The occurrence of DV is negatively associated with the educational level of spouses but studies dealing with educational discrepancies of spouses show contradicting results: Wives with higher education than their husbands were more likely to ever experience DV as compared to equally educated couples. The purpose of this study was to investigate the association between spousal education gap (SEG) and the prevalence and severity of DV in India and Bangladesh. Nationally representative data collected through the 2005/2006 Indian National Family Health Survey (NFHS-3) and 2007 Bangladesh Demographic and Health Survey (BDHS) were used. In total, we analysed data of 69,805 women aged 15-49 years (Bangladesh: 4,195 women, India: 65,610 women). In addition to univariate and bivariable analyses, a multinomial logistic regression model was used to quantify the association between education gap and less severe as well as severe domestic violence. Adjustment was made for age, religion, and family structure. Wives with higher education than their husbands were less likely to experience less severe (OR = 0.83, 95% CI: 0.77-0.89) and severe (OR = 0.79, 95% CI: 0.72-0.87) DV as compared to equally low-educated spouses (reference group). Equally high-educated couples revealed the lowest likelihood of experiencing DV (severe violence: OR 0.43, CI 0.39-0.48; less severe violence: OR 0.59, CI 0.55-0.63). The model's goodness of fit was low (Nagelkerke's R2 = 0.152). Our analysis revealed no increased DV among wives with a higher educational level than their husbands. Moreover, the results point towards a decrease of severe violence with an increase in education levels among spouses. However, the model did not explain a satisfying amount of DV. Therefore, further research should be done to reveal unknown determinants so that suitable interventions to reduce DV can be

In total, we analysed data of 69,805 women aged 15–49 years (Bangladesh: 4,195 women, India: 65,610 women. In addition to univariate and bivariable analyses, a multinomial logistic regression model was used to quantify the association between education gap and less severe as well as severe domestic violence. Adjustment was made for age, religion, and family structure. Results Wives with higher education than their husbands were less likely to experience less severe (OR = 0.83, 95% CI: 0.77–0.89 and severe (OR = 0.79, 95% CI: 0.72–0.87 DV as compared to equally low-educated spouses (reference group. Equally high-educated couples revealed the lowest likelihood of experiencing DV (severe violence: OR 0.43, CI 0.39–0.48; less severe violence: OR 0.59, CI 0.55–0.63. The model’s goodness of fit was low (Nagelkerke’s R2 = 0.152. Conclusions Our analysis revealed no increased DV among wives with a higher educational level than their husbands. Moreover, the results point towards a decrease of severe violence with an increase in education levels among spouses. However, the model did not explain a satisfying amount of DV. Therefore, further research should be

    FTV (Free-viewpoint Television) is 3DTV with infinite number of views and ranked as the top of visual media. It enables to view a 3D world by freely changing the viewpoint. MPEG has been promoting the international standardization of FTV since 2001. The first phase of FTV is MVC (Multi-view Video Coding) and the second phase of FTV is 3DV (3D Video). MVC completed in 2009 encodes multiple camera views efficiently and has been adopted by Blu-ray 3D. 3DV is a standard that targets serving a variety of 3D displays and is currently in progress. 3DV employs MVD (Multi-View and Depth) for data format. MVD is a set of views and depths at various viewpoints. 3DV sends MVD data at a few viewpoints and synthesizes many views at other viewpoints to be displayed on various types of multi-view displays at the receiver side. The 3DV activity moved to the Joint Collaborative Team on 3D Video Coding Extension Development (JCT-3V) of MPEG and ITU in July 2012. We propose GVD (Global View and Depth) as an alternative data format. GVD consists of base view, base depth, residual views and residual depths. GVD is a compact 3D expression compared to MVD since redundancy of MVD is removed in GVD. GVD has been accepted in JCT-3V.

    Full Text Available Domestic violence (DV is a form of gender-based violence and a violation of human rights. As such, it was analyzed from the perspective of feminist theory in the dissertation this article is based on, by analyzing discourse pragmatics. Which are the socially accepted DV discourses in Uruguay? Which coincidences, contradictions, and paradoxes appear when we compare these discourses and those of everyday life? Which codes and subcodes should be modified by the sectors interested in the prevention and eradication of DV? The main hypothesis is that there are different types of opposition between the public discourse of different institutional sectors and that of everyday life. Describing these oppositions and, especially, unveiling the pragmatic paradoxes will enable us to develop a different type of discourse for the prevention and eradication of DV. As I am both a researcher and an activist on the topic, my epistemological choice was the autoethnography. This article provides some final reflections, included in the dissertation, on how the feminist movement needs to succeed in persuading decision makers and the mass media, and in building solid alliances to establish an information and monitoring system; the integration of the subject into the educational system; comprehensive legislation on gender-based violence; and new ways of communicating with all sectors, so as to create a new ideology on gender relations for the suitable prevention of DV.

    There is increasing recognition of the potential importance of viral burden in the pathogenesis of dengue hemorrhagic fever (DHF). There is little data available, however, describing the kinetics of viral replication in humans with natural dengue virus (DV) infection. Standard procedures for measuring titers of infectious virus in clinical specimens are either laborious or insensitive. We developed a method for measurement of DV RNA in plasma samples based on reverse transcription-polymerase chain reaction (RT-PCR) using a mutant RNA target as a competitor. This technique was reproducible and accurate for samples containing any of the four DV serotypes, and could be applied to samples containing as few as 250 copies of RNA per reaction. We examined plasma viral RNA levels in 80 children with acute DV infection; sequential plasma samples were tested in 34 of these children. Plasma viral RNA levels ranged as high as 10(9) RNA copies/ml, and correlated with titers of infectious virus measured in mosquitoes (r= 0.69). Plasma viral RNA levels fell rapidly during the last several days of the febrile period. We did not find a significant difference in maximal plasma viral RNA levels between children with DHF and children with dengue fever, but peak viral RNA levels were identified in only 16 subjects. We conclude that this quantitative RT-PCR method will be valuable for further studies of natural DV infections.

    2014-04-01

    Domestic violence (DV) continues to constitute an enormous public health problem in the United States. Knowledge and understanding of the complexities involved in DV has grown significantly in recent years revealing a need for providers who have broad training in a variety of legal, safety, developmental, and clinical issues that face families impacted by DV. This paper reviews current approaches to training and the ability of such methods to adequately prepare providers. There are no national standards for providers at any level from DV advocates to batterer interventionists, to clinicians with the required hours of training in most states at an alarmingly low level. Few states require cross training for those working as victim advocates or batterer interventionists. The systems that currently provide segregated and limited training create silos of service that are less effective. A proposed set of standards and training guidelines are proposed for DV advocates, batterer interventionists, and clinicians along with a discussion of the implications of such standards for the field.

    There are discrepancies about whether children who witness and suffer domestic violence (DV) have similar outcomes in terms of psychopathology. This work examines the relationship between different types of exposure to DV and child psychopathology and functional impairment. One hundred and forty-four Spanish children aged from 4 to 17 years and exposed to DV were evaluated using a diagnostic interview and other instruments of psychopathology and functional impairment. The participants were classified in three groups according to the degree of exposure: witness (n = 72), involved (n = 52), and victim (n = 20). According to mothers' self-reports and mother-child combined information, DV equally affects psychopathology and functional impairment regardless of the degree of the exposure. Children's self-reports showed a linear trend to present greater psychopathology as a victim than as a witness. The differential effect of exposure to DV measured in this study depended on the informant, which underlines the importance of obtaining information from the children exposed to violence at home.

    Canine distemper virus (CDV) has recently expanded its host range to nonhuman primates. A large CDV outbreak occurred in rhesus monkeys at a breeding farm in Guangxi Province, China, in 2006, followed by another outbreak in rhesus monkeys at an animal center in Beijing in 2008. In 2008 in Japan, a CDV outbreak also occurred in cynomolgus monkeys imported from China. In that outbreak, 46 monkeys died from severe pneumonia during a quarantine period. A CDV strain (CYN07-dV) was isolated in Vero cells expressing dog signaling lymphocyte activation molecule (SLAM). Phylogenic analysis showed that CYN07-dV was closely related to the recent CDV outbreaks in China, suggesting continuing chains of CDV infection in monkeys. In vitro, CYN07-dV uses macaca SLAM and macaca nectin4 as receptors as efficiently as dog SLAM and dog nectin4, respectively. CYN07-dV showed high virulence in experimentally infected cynomolgus monkeys and excreted progeny viruses in oral fluid and feces. These data revealed that some of the CDV strains, like CYN07-dV, have the potential to cause acute systemic infection in monkeys.

    Full Text Available Ingestion of double stranded RNA (dsRNA has been previously demonstrated to be effective in triggering RNA interference (RNAi in western corn rootworm (WCR, Diabrotica virgifera virgifera LeConte, providing potential novel opportunities for insect pest control. The putative Snf7 homolog of WCR (DvSnf7 has previously been shown to be an effective RNAi target for insect control, as DvSnf7 RNAi leads to lethality of WCR larvae. Snf7 functions as a part of the ESCRT (Endosomal Sorting Complex Required for Transport pathway which plays a crucial role in cellular housekeeping by internalization, transport, sorting and lysosomal degradation of transmembrane proteins. To understand the effects that lead to death of WCR larvae by DvSnf7 RNAi, we examined some of the distinct cellular processes associated with ESCRT functions such as de-ubiquitination of proteins and autophagy. Our data indicate that ubiquitinated proteins accumulate in DvSnf7 dsRNA-fed larval tissues and that the autophagy process seems to be impaired. These findings suggest that the malfunctioning of these cellular processes in both midgut and fat body tissues triggered by DvSnf7 RNAi were the main effects leading to the death of WCR. This study also illustrates that Snf7 is an essential gene in WCR and its functions are consistent with biological functions described for other eukaryotes.

    Dengue is the most frequent hemorrhagic viral disease and re-emergent infection in the world. Although thrombocytopenia is characteristically observed in mild and severe forms of dengue, the role of platelet activation in dengue pathogenesis has not been fully elucidated. We hypothesize that platelets have major roles in inflammatory amplification and increased vascular permeability during severe forms of dengue. Here we investigate interleukin (IL)-1β synthesis, processing, and secretion in platelets during dengue virus (DV) infection and potential contribution of these events to endothelial permeability during infection. We observed increased expression of IL-1β in platelets and platelet-derived microparticles from patients with dengue or after platelet exposure to DV in vitro. We demonstrated that DV infection leads to assembly of nucleotide-binding domain leucine rich repeat containing protein (NLRP3) inflammasomes, activation of caspase-1, and caspase-1-dependent IL-1β secretion. Our findings also indicate that platelet-derived IL-1β is chiefly released in microparticles through mechanisms dependent on mitochondrial reactive oxygen species-triggered NLRP3 inflammasomes. Inflammasome activation and platelet shedding of IL-1β-rich microparticles correlated with signs of increased vascular permeability. Moreover, microparticles from DV-stimulated platelets induced enhanced permeability in vitro in an IL-1-dependent manner. Our findings provide new evidence that platelets contribute to increased vascular permeability in DV infection by inflammasome-dependent release of IL-1β.

    The pathogenic mechanisms of dengue hemorrhagic fever and dengue shock syndrome (DHF/DSS) caused by dengue virus (DV) infection remain unresolved. Patients with DHF/DSS are characterized by several manifestations, including severe thrombocytopenia, vascular leakage, and hepatomegaly. In addition to the effect of virus load and virus variation, abnormal immune responses of the host after DV infection may also account for the progression of DHF/DSS. Actually, viral autoimmunity is involved in the pathogenesis of numerous viral infections, such as human immunodeficiency virus, human hepatitis C virus, human cytomegalovirus, herpes simplex virus, Epstein- Barr virus, and DV. In this review, we discuss the implications of autoimmunity in dengue pathogenesis. Antibodies directed against DV nonstructural protein 1 (NS1) showed cross-reactivity with human platelets and endothelial cells, which lead to platelet and endothelial cell damage and inflammatory activation. Based on these findings, we hypothesize that anti-DV NS1 is involved in the pathogenesis of DF and DHF/DSS, and this may provide important information in dengue vaccine development.

    We analyzed the binding of P.rβ₂-GPI-DV with ox-LDL by fluorescence, molecular simulation and circular dichroism. We used SDS-PAGE and Western blotting to identify the purity of P.rβ₂-GPI-DV, fluorescence, circular dichroism spectroscopy and molecular docking simulation to analyze the binding between P.rβ₂-GPI-DV and oxLDL. P.rβ₂-GPI-DV was specifically recognized by anti-His antibody at 12 kDa position. The chromophoric groups, the changes of secondary structure and the molecular docking simulations revealed that the active pocket formed by Cys281-Lys-Asn-Lys-Glu-Lys-Lys287 and Leu313-Ala-Phe-Trp316 of P.rβ₂-GPI-DV and the -COOH carboxyl of oxLig-1 were the key for binding. P.rβ₂-GPI combined with ox-LDL via the fifth functional domain and the -COOH group. Our findings provide theoretical basis to further study the binding between β₂-GPI and ox-LDL in serum.

    The Inventory Déjà Vu Experiences Assessment (IDEA) is the only screening instrument proposed to evaluate the Déjà vu (DV) experience. Here, we intended to validate the Italian version of IDEA (I-IDEA) and at the same time to investigate the incidence and subjective qualities of the DV phenomenon in healthy Italian adult individuals on basis of an Italian multicentre observational study. In this study, we report normative data on the I-IDEA, collected on a sample of 542 Italian healthy subjects aging between 18-70 years (average age: 40) with a formal educational from 1-19 years. From September 2013 to March 2016, we recruited 542 healthy volunteers from 10 outpatient neurological clinics in Italy. All participants (i.e., family members of neurological patients enrolled, medical students, physicians) had no neurological or psychiatric illness and gave their informed consent to participate in the study. All subjects enrolled self-administered the questionnaire and they were able to complete I-IDEA test without any support. In total, 396 (73%) of the 542 healthy controls experienced the DV phenomenon. The frequency of DV was inversely related to age as well as to derealisation, jamais vu, precognitive dreams, depersonalization, paranormal activity, remembering dreams, travel frequency, and daydreams (all p Italian version of IDEA maintains good properties, thus confirming that this instrument is reliable for detecting and characterising the DV phenomenon.

    Full Text Available Vaccines against dengue virus (DV are commercially nonexistent. A subunit vaccination strategy may be of value, especially if a safe viral vector acts as biologically active adjuvant. In this paper, we focus on an immunoglobulin-like, independently folded domain III (DIII from DV 2 envelope protein (E, which contains epitopes that elicits highly specific neutralizing antibodies. We modified the hepatitis B small surface antigen (HBsAg, S in order to display DV 2 DIII on a virus-like particle (VLP, thus generating the hybrid antigen DIII-S. Two varieties of measles virus (MV vectors were developed to express DIII-S. The first expresses the hybrid antigen from an additional transcription unit (ATU and the second additionally expresses HBsAg from a separate ATU. We found that this second MV vectoring the hybrid VLPs displaying DIII-S on an unmodified HBsAg scaffold were immunogenic in MV-susceptible mice (HuCD46Ge-IFNarko, eliciting robust neutralizing responses (averages against MV (1:1280 NT90, hepatitis B virus (787 mIU/mL, and DV2 (1:160 NT50 in all of the tested animals. Conversely, the MV vector expressing only DIII-S induced immunity against MV alone. In summary, DV2 neutralizing responses can be generated by displaying E DIII on a scaffold of HBsAg-based VLPs, vectored by MV.

    Dead space fraction (V d/V t) measurement performed using volumetric capnography requires arterial blood gas (ABG) sampling to estimate the partial pressure of carbon dioxide (PaCO2). In recent years, transcutaneous capnography (PtcCO2) has emerged as a noninvasive method of estimating PaCO2. We hypothesized that PtcCO2 can be used as a substitute for PaCO2 in the calculation of V d/V t. In this prospective pilot comparison study, 30 consecutive postcardiac surgery mechanically ventilated patients had V d/V t calculated separately using volumetric capnography by substituting PtcCO2 for PaCO2. The mean V d/V t calculated using PaCO2 and PtcCO2 was 0.48 ± 0.09 and 0.53 ± 0.08, respectively, with a strong positive correlation between the two methods of calculation (Pearson's correlation = 0.87, p < 0.05). Bland-Altman analysis showed a mean difference of -0.05 (95% CI: -0.01 to -0.09) between the two methods. PtcCO2 measurements can provide a noninvasive means to measure V d/V t, thus accessing important physiologic information and prognostic assessment in patients receiving mechanical ventilation.

    We present a statistical study of velocities of Lya, interstellar (IS) absorption, and nebular lines and gas covering fraction for Lya emitters (LAEs) at z~2. We make a sample of 22 LAEs with a large Lya equivalent width (EW) of > 50A based on our deep Keck/LRIS observations, in conjunction with spectroscopic data from the Subaru/FMOS program and the literature. We estimate the average velocity offset of Lya from a systemic redshift determined with nebular lines to be dv_Lya=234+-9 km s-1. Using a Kolmogorv-Smirnov test, we confirm the previous claim of Hashimoto et al. (2013) that the average dv_Lya of LAEs is smaller than that of LBGs. Our LRIS data successfully identify blue-shifted multiple IS absorption lines in the UV continua of four LAEs on an individual basis. The average velocity offset of IS absorption lines from a systemic redshift is dv_IS=204+-27 km s-1, indicating LAE's gas outflow with a velocity comparable to typical LBGs. Thus, the ratio, R^Lya_ IS = dv_Lya/dv_IS of LAEs, is around unity, su...

    DV encompasses a wide variety of actions that coerce, control, or demean the victim. Victims of DV suffer many physical and mental health consequences that cause emergency physicians to encounter them knowingly or unknowingly in the medical setting. Physicians who are aware of the prevalent problem of DV are able to help victims the most. A physician should be educated to recognize the physical and emotional presentations of victims, but, more importantly, the physician should be knowledgeable about the need for screening of all patients to reach the greatest number of victims. Victims often are not ready or able to disclose DV because of patient and physician barriers. Clinicians should work to overcome these barriers by initiating screening, ensuring patient comfort and safety, and understanding the many stages involved in behavioral change that a victim must traverse. The emergency physician would experience less frustration and more success if he or she would change their role from problem solver to listener and empowerer. This approach allows the survivor to make informed choices. Patients who are ready to make changes must be provided with protection,treatment, resources, and support. Informed, active physicians have great potential for improving DV victims' lives, reducing the effects of violence,and facilitating the patient's progression from victim to survivor.

    In this paper, we develop an effective method for detecting weak molecular bonding between the dengue virus (DV) and its receptor C-type lectin domain family 5, member A (CLEC5A). The CLEC5A-DV interaction is critical for DV-induced hemorrhagic fever and shock syndrome, so the sensing of CLEC5A-DV binding is crucial to realize a thorough study of the pathogenesis of dengue fever. Through a highly sensitive nanostructured sensing electrode of gold nanoparticles (GNPs) uniformly deposited on a nanohemisphere array, a label-free detection of the ultra weak binding between CLEC5A and the DV can be performed with electrochemical impedance spectroscopy (EIS). Experimental results demonstrate that the proposed approach is a highly promising method for investigating weak molecular interactions such as the ligand-receptor interaction of dengue fever, enterovirus (EV), or the interaction between cancer surface glycoproteins and their receptors. Authors of this study investigated the ultra-weak binding between dengue virus and its CLEC5A receptor via electrochemical impedance spectroscopy and gold NP sensing electrode. Similar methods may be applicable in other infections and in cancer models as well. Copyright © 2014 Elsevier Inc. All rights reserved.

    This study was designed to determine if desvenlafaxine (DV), a serotonin-norepinephrine reuptake inhibitor, can attenuate apoptosis observed in the limbic system after myocardial infarction (MI). MI was induced in rats by occlusion of the left descending artery for 40 min followed by reperfusion. Another group of sham (control) rats was similarly manipulated, but without occlusion. Half of the full cohort received DV (3 mg/kg/day intraperitoneal), starting 5 min after the onset of reperfusion; the other half received the vehicle (0.5 ml of 0.9% saline). Rats were sacrificed after 3 days for biochemical analyses and MI size measurements. Infarct size was significantly smaller in DV- compared to vehicle-treated rats. At 3 days post-MI, caspase-3 and -8 activities and terminal deoxynucleotidyltransferase-mediated dUTP nick-end labeling-positive cells were decreased in the amygdala of DV-treated rats compared to MI-vehicle controls. No difference was observed between the sham groups. The data indicates that DV given immediately after an acute MI event can reduce MI size and apoptosis in amygdala when measured three days post-MI.

    2015-03-15

    Leveraging on the enzymatic processing of Dengue virus (DV) RNA hybridized quantum dot-capped DNA capture probes (QD-CPs), an ultrasensitive assay for the detection and serotyping of DVs is described in the report. Briefly, DV-specific DNA CPs are first capped by QDs and then conjugated to magnetic beads. In a sample solution, strands of DV RNA form heteroduplexes with the QD-CPs on the magnetic beads. The CPs together with the QDs in the heteroduplexes are subsequently cleaved off the magnetic beads by a duplex-specific nuclease (DSN), releasing the QDs to the solution, freeing the target RNA strands, and availing them for another around of hybridization with the remaining QD-CPs. After removing the magnetic beads along with unreacted (uncleaved) QD-CPs by using a permanent magnet, ultrasensitive fluorescent detection of DV is realized through the cleaved QDs. Serotyping of DV is accomplished by a judicious design of the QD-CPs. The assay combines excellent signal generation by the highly fluorescent QDs and the effortlessness of utilizing magnetic beads in the removal of the unreacted QD-CPs. The highly efficient DSN cleavage in conjunction with its excellent mismatch discrimination ability permits serotyping of DVs in one tube with excellent sensitivity and selectivity.

    The influence of pressure on the density of six base fluids is experimentally studied for a range of pressures from 0.422 to 2.20 GPa. An important parameter used to describe the results is the change in relative volume with change in pressure dv sub r/dp. For pressures less than the solidification pressure (p ps) a small change in pressure results in a large change in dv sub r/ps. For pressures greater than the solidification pressure (p ps) there is no change in dv sub r/dp with changing pressure. The solidification pressures of the base fluids varies considerably, as do the slopes that the experimental data assumes for p ps. A new formula is developed that describes the effect of pressure on density in terms of four constants. These constants vary for the different base fluids tested.

A meta-analysis of interview-based data excerpts appearing in published studies shows how the response to DV in the Arab community, though consistent with Israeli law and policy, creates a sense of paralysis for the police and frustration for the parties to the violence as well as the affected communities. The cultural, social, and political forces that underlie the dynamics, tensions, and pressures experienced by the various parties are analyzed in the context of everyday life amid concerns about the Israeli-Arab conflict. The implications for policing DV in minority communities, and for police-community relations in political conflict zones, are highlighted. © The Author(s) 2014.

    High dietary intakes of some protein sources, including soy protein, can increase colonic DNA damage in animals, whereas some carbohydrates attenuate this. We investigated whether inulin and xylo-oligosaccharides (XOS) could be protective against DNA strand breaks by adding them to a human colonic...... cornstarch for 10 day followed by soy protein with 1% XOS or 1% inulin for 10 day. Inulin did not alter genotoxicity but XOS significantly reduced PV genotoxicity and increased DV genotoxicity. Inulin and XOS significantly increased butyrate concentration in the DV but not PV. Numbers of the key butyrate......-producing bacterium Faecalibacterium prausnitzii were significantly increased in the PV and DV by inulin but significantly decreased by XOS in both vessels. Other bacteria examined were also significantly impacted by the carbohydrate treatments or by the vessel (i.e., pH). There was a significant overall inverse...

    This article is based on an analysis of the life history narrative of Antonia, a Peruvian immigrant in Chile, in the context of ethnographic research on Chilean women's experiences of domestic violence (DV) and the post-dictatorship state's responses to DV. Structural and socio-cultural constraints and forms of violence, including global and local economic inequalities, migration, racism, and intimate, gender-based abuses in both home and receiving countries interact in Antonia's experience to produce suffering and influence a form of gendered agency. This analysis points to the need for research and policies specifically designed to attend to the intersecting vulnerabilities migrant women who suffer DV often face, as well as their agentive acts.

    We briefly discuss the recent claims that the ordinary KP/Toda integrability, which is a characteristic property of ordinary eigenvalue matrix models, persists also for the Dijkgraaf-Vafa (DV) partition functions and for the refined topological vertex. We emphasize that in both cases what is meant is a particular representation of partition functions: a peculiar sum over all DV phases in the first case and hiding the deformation parameters in a sophisticated potential in the second case, i.e. essentially a reformulation of some questions in the new theory in the language of the old one. It is at best obscure if this treatment can be made consistent with the AGT relations and even with the quantization of the underlying integrable systems in the Nekrasov-Shatashvili limit, which seem to require a full-scale {beta}-deformation of individual DV partition functions. Thus, it is unclear if the story of integrability is indeed closed by these recent considerations.

  16. Readers, Texts, and the Fusion of Horizons: Theology and Gadamer’s Hermeneutics

    Matthew W. Knotts

    2014-12-01

    Full Text Available The practise of hermeneutics originates in a theological context, and indeed, the work of Hans-Georg Gadamer has exerted an influence over theologians and religious persons for the last half century. What if any relevance does a text, for instance, a biblical one, have for us today? Is it severed from us due to its historical and temporal distance? Even if it has some message which can be relevant today, how is one to access and interpret it? Gadamer deals with such issues in his masterwork Truth and Method, offering resources through his understanding of the nature of texts and what he calls the fusion of horizons. For Gadamer, an horizon constitutes one’s worldview. Yet this horizon is subject to expansion and revision, as well as contact with other horizons. In this process of fusing horizons, understanding occurs between minds, and one grows in one’s awareness and pursuit of truth. Gadamer maintains that this can happen across both hermeneutical and historical boundaries, hence preserving the applicability of a text to a different context without compromising its unique historical origins. Čtenář, text a splývání jejich horizontů: Teologie a Gadamerova hermeneutika Zájem o hermeneutiku se zrodil v teologickém prostředí. Jednou z nejvlivnějších postav a vzorů hermeneutiky od poloviny minulého století až dodnes se stal Hans-Georg Gadamer. Jaký má pro nás, lidi 21. století, smysl biblický text? Nebo se zeptejme takto: má pro nás vůbec nějaký smysl? Je od nás časově i dějinně vzdálen. I kdyby pro nás nějaké poselství přece jen měl, otázkou zůstává, jak jej interpretovat? Těmito a podobnými otázkami se zabývá Gadamer ve svém životním díle Pravda a Metoda. Ukazuje, jak s takovými texty pracovat. Jako klíče využívá způsob porozumění charakteru textů a to, čemu říká splývání horizontů. Horizontem se podle Gadamera rozumí náš světonázor. Každý horizont se rozp

    Garden dahlias (Dahlia variabilis) are autoallooctoploids with redundant genes producing wide color variations in flowers. There are no pure white dahlia cultivars, despite its long breeding history. However, the white areas of bicolor flower petals appear to be pure white. The objective of this experiment was to elucidate the mechanism by which the pure white color is expressed in the petals of some bicolor cultivars. A pigment analysis showed that no flavonoid derivatives were detected in the white areas of petals in a star-type cultivar 'Yuino' and the two seedling cultivars 'OriW1' and 'OriW2' borne from a red-white bicolor cultivar, 'Orihime', indicating that their white areas are pure white. Semi-quantitative RT-PCR showed that in the pure white areas, transcripts of two chalcone synthases (CHS), DvCHS1 and DvCHS2 which share 69% nucleotide similarity with each other, were barely detected. Premature mRNA of DvCHS1 and DvCHS2 were detected, indicating that these two CHS genes are silenced post-transcriptionally. RNA gel blot analysis revealed that small interfering RNAs (siRNAs) derived from CHSs were produced in these pure white areas. By high-throughput sequence analysis of small RNAs in the pure white areas with no mismatch acceptance, small RNAs were mapped to two alleles of DvCHS1 and two alleles of DvCHS2 expressed in 'Yuino' petals. Therefore, we concluded that simultaneous siRNA-mediated post-transcriptional gene silencing of redundant CHS genes results in the appearance of pure white color in dahlias.

It was applied to the third stage of DV- Hop algorithm, the node's position correction, the quantum genetic algorithm was used to get the optimal solution of the model and the optimal estimation position of the unknown nodes can be gotten. Compared with the original algorithm, improved DV-hop localization algorithm can improve the problem of low position coverage and has higher precision in the low proportion of anchor nodes.

    Preferential streaming of the ductus venosus (DV) toward the right atrium has been observed in fetuses with left diaphragmatic hernia (LDH). The purpose of this retrospective study was to compare survival rates to discharge between a group with preferential streaming of the DV toward the right heart and a group in which this abnormal flow pattern was not present. We retrospectively searched our patient records for fetuses with LDH in whom liver position, DV streaming and postnatal outcome information was available. 55 cases were found and divided into two groups: Group I fetuses exhibited abnormal DV streaming toward the right side of the heart; group II fetuses did not. Various prognostic and outcome parameters were compared. 62 % of group I fetuses and 88 % of group II fetuses survived to discharge (p = 0.032). Fetoscopic tracheal balloon occlusion (FETO) was performed in 66 % of group I fetuses and 23 % of group II fetuses (p = 0.003). Postnatal ECMO therapy was performed in 55 % of group I fetuses and 23 % of group II infants (p = 0.025). Moderate to severe chronic lung disease in survivors was observed in 56 % of the survivors of group I and 9 % of the survivors of group II (p = 0.002). Preferential streaming of the DV toward the right heart in human fetuses with left-sided diaphragmatic hernia was associated with a poorer postnatal outcome despite a higher rate of invasive pre- and postnatal procedures compared to fetuses without this flow abnormality. Specifically, abnormal DV streaming was found to be an independent predictor for FETO. © Georg Thieme Verlag KG Stuttgart · New York.

    Dengue virus (DV) is a flavivirus and infects mammalian cells through mosquito vectors. This study investigates the roles of domain III of DV type 2 envelope protein (EIII) in DV binding to the host cell. Recombinant EIII interferes with DV infection to BHK21 and C6/36 cells by blocking dengue virion adsorption to these cells. Inhibition of EIII on BHK21 cells was broad with no serotype specificity; however, inhibition of EIII on C6/36 cells was relatively serotype specific. Soluble heparin completely blocks binding of EIII to BHK21 cells, suggesting that domain III binds mainly to cell surface heparan sulfates. This suggestion is supported by the observation that EIII binds very weakly to gro2C and sog9 mutant mammalian cell lines that lack heparan sulfate. In contrast, heparin does not block binding of EIII to mosquito cells. Furthermore, a synthetic peptide that includes amino acids (aa) 380 to 389 of EIII, IGVEPGQLKL, inhibits binding of EIII to C6/36 but not BHK21 cells. This peptide corresponds to a lateral loop region on domain III of E protein, indicating a possible role of this loop in binding to mosquito cells. In summary, these results suggest that EIII plays an important role in binding of DV type 2 to host cells. In addition, EIII interacts with heparan sulfates when binding to BHK21 cells, and a loop region containing aa 380 to 389 of EIII may participate in DV type 2 binding to C6/36 cells.

    The stable isotopic composition of water vapour provides information about moisture sources and processes difficult to obtain with traditional measurement techniques. Recently, it has been proposed that the D-excess of water vapour (dv = δ2H - 8 × δ18O) can provide a diagnostic tracer of continental moisture recycling. However, D-excess exhibits a diurnal cycle that has been observed across a variety of ecosystems and may be influenced by a range of processes beyond regional-scale moisture recycling, including local evaporation (ET) fluxes. There is a lack of measurements of D-excess in evaporation (ET) fluxes, which has made it difficult to assess how ET fluxes modify the D-excess in water vapour (dv). With this in mind, we employed a chamber-based approach to directly measure D-excess in ET (dET) fluxes. We show that ET fluxes imposed a negative forcing on the ambient vapour and could not explain the higher daytime dv values. The low dET observed here was sourced from a soil water pool that had undergone an extended drying period, leading to low D-excess in the soil moisture pool. A strong correlation between daytime dv and locally measured relative humidity was consistent with an oceanic moisture source, suggesting that remote hydrological processes were the major contributor to daytime dv variability. During the early evening, ET fluxes into a shallow nocturnal inversion layer caused a lowering of dv values near the surface. In addition, transient mixing of vapour with a higher D-excess from above the nocturnal inversion modified these values, causing large variability during the night. These results indicate doceanic moisture source.

    Proposed variations to Nutrition Facts Labels (NFL) have included the display of added sugars (AS) content, but its impact on consumer understanding is poorly understood. To examine the degree to which different formats for displaying AS influence consumer understanding, perceptions, and purchase intentions. Randomized-controlled online experiment. A sample of 2509 U.S adults. Participants were randomized to 1 of 8 conditions and viewed 10 food or beverage images with either: (1) no label (control); (2) the current NFL (without AS); (3) the proposed NFL without AS; or the proposed NFL with AS in (4) grams, (5) grams and teaspoons, (6) grams and percent Daily Value (%DV), (7) grams with high/medium/low text, or (8) grams with high/medium/low text and %DV. ANCOVAs compared scores on quizzes that assessed the accuracy of judgments about AS, overall nutrition understanding and purchase intentions. Presenting AS in grams plus high/medium/low text with and without %DV led to the highest AS understanding scores (85% and 83% correct, respectively) compared to 70% correct when AS was not on the label or was displayed in grams only (74% correct). Displaying AS in teaspoons did not significantly improve understanding beyond grams alone. Consumers were best able to determine which of two products was healthier when AS was presented as %DV (68% correct) versus displayed in grams alone (60% correct), but %DV did not differ from high/medium/low text or teaspoons. None of the labels influenced purchase intentions relative to no label. Displaying AS on the NFL in grams with high/medium/low text, %DV, or the combination of the two, improved consumer understanding more than presenting it in grams or teaspoons.

  6. Epitope Mapping of Dengue-Virus-Enhancing Monoclonal-Antibody Using Phage Display Peptide Library

    Directory of Open Access Journals (Sweden)

    2008-01-01

    Full Text Available The Antibody-Dependent Enhancement (ADE hypothesis has been proposed to explain why more severe manifestations of Dengue Hemorrhagic Fever and Dengue Shock Syndrome (DHF/DSS occur predominantly during secondary infections of Dengue Virus (DV with different serotypes. However, the epitopes recognized by these enhancing antibodies are unclear. Recently, anti-pre-M monoclonal antibody (mAb 70-21, which recognized all DV serotypes without neutralizing activity, were generated and demonstrated as an enhancing antibody for DV infection. In the present study, the epitope recognized by mAb 70-21 was identified using a phage-displayed random-peptide library. After three rounds of biopanning, ELISA showed that immunopositive phage clones specifically bound to mAb 70-21 but not to serum or purified IgG from naive mice. DNA sequencing of these phage clones showed a consensus sequence, QNNLGPR. Like mAb70-21, these phage-induced antisera also enhanced the DV infection of cells. In addition, indirect fluorescent assays showed phage-induced antisera bound to human rhabdomyosarcoma or Vero cells. Western blotting and immunoprecipitation analysis showed that phage-induced antisera recognized hsp 60 in BHK cell lysate. Moreover, the sera levels of antibodies against the synthetic peptide QNNLGPR correlated with the disease severity of dengue patients. Taken together, these results suggest that antibodies which recognized epitopes shared by pre-M of DV and hsp 60 of host cells may enhance DV infection and be involved in the development of DHF or DSS.

    Dengue is the most prevalent arboviral disease worldwide. The outcome of the infection is determined by the interplay of viral and host factors. In the present study, we evaluated the cellular response of human monocyte-derived DCs (mdDCs) infected with recombinant dengue virus type 1 (DV1) strains carrying a single point mutation in the NS3hel protein (L435S or L480S). Both mutated viruses infect and replicate more efficiently and produce more viral progeny in infected mdDCs compared with the parental, non-mutated virus (vBACDV1). Additionally, global gene expression analysis using cDNA microarrays revealed that the mutated DVs induce the up-regulation of the interferon (IFN) signalling and pattern recognition receptor (PRR) canonical pathways in mdDCs. Pronounced production of type I IFN were detected specifically in mdDCs infected with DV1-NS3hel-mutated virus compared with mdDCs infected with the parental virus. In addition, we showed that the type I IFN produced by mdDCs is able to reduce DV1 infection rates, suggesting that cytokine function is effective but not sufficient to mediate viral clearance of DV1-NS3hel-mutated strains. Our results demonstrate that single point mutations in subdomain 2 have important implications for adenosine triphosphatase (ATPase) activity of DV1-NS3hel. Although a direct functional connection between the increased ATPase activity and viral replication still requires further studies, these mutations speed up viral RNA replication and are sufficient to enhance viral replicative capacity in human primary cell infection and circumvent type I IFN activity. This information may have particular relevance for attenuated vaccine protocols designed for DV.

    Full Text Available Hlavní překážky přirozeného vývoje Krušnohorského regionu jsou v oblasti duchovní: vykořeněnost, zpřetrhání tradic, mělký vztah obyvatel k jejich domovu. Jestli se chceme vyhnout představě Ústeckého kraje jako prolákliny mezi Českým středohořím a Krušnými horami zalitými vodami Baltského moře, ve kterém ukryjeme všechny ty nepodařené pokusy 20. století o soužití a živobytí, a hřebenů Krušných hor jako podstavce pro větrné a solární elektrárny ne nepodobné sci-fi vyobrazením z jiných planet, je nutné začít ve zdejších obyvatelích rozfoukávat bazální pocity zakořenění a konservativnosti. Překonat zažitou představu o území obětovaném abstraktním ekonomickým projektům a nesmyslným velikášským plánům, které místním lidem pocit domova rozhodně nepřibližují, s sebou ovšem nese jistou míru zarputilosti, odvahy a vytrvalosti.

S využitím starých topografických map byl vyhodnocen vývoj využití krajiny a proveden rozbor hybných sil změn využití krajiny. Zásadní změny využití krajiny jsou v tomto území spojeny s procesy zemědělské intenzifikace a urbanizace. Nejvyšší výměra vodních ploch byla zaznamenána v obou povodích v roce 1763. V druhé polovině 19. století se významně projevily zásadní hybné síly vedoucí k zániku většiny vodních ploch v obou povodích. Po druhé světové válce došlo k obnově některých vodních ploch v povodí Kyjovky, zároveň byly zakládány i nové rybníky. Naopak v povodí Trkmanky nebyly obnoveny žádné významné vodní plochy.

Tato studie se zabývá rozvojem gay podniků a ne-rezidenčních míst za použití analýzy hlavních komponent aplikované na datech získaných ze Spartacus International Gay Guide 2007. Tento kvantitativní přístup je v oboru převážně kvalitativních geografií sexualit poněkud nezvyklý. Díky tomu byly identifikovány gay komodifikace a gay (neviditelnosti jako nejpravděpodobnější faktory vysvětlující prostorovou diverzitu zkoumaných gay míst. Tyto dva faktory jsou analyzovány z hlediska jejich spojitostí, specifik a regionální významnosti. Následně jsou hodnoceny interakce v rámci ekonomických, kulturních a sociálních faktorů působících při rozvoji gay podniků a gay ne-rezidenčních míst napříč Evropou.

    A canine distemper virus (CDV) strain, CYN07-dV, associated with a lethal outbreak in monkeys, used human signaling lymphocyte activation molecule as a receptor only poorly but readily adapted to use it following a P541S substitution in the hemagglutinin protein. Since CYN07-dV had an intrinsic ability to use human nectin-4, the adapted virus became able to use both human immune and epithelial cell receptors, as well as monkey and canine ones, suggesting that CDV can potentially infect humans.

  18. Environmental fate of double-stranded RNA in agricultural soils.

    Directory of Open Access Journals (Sweden)

    Full Text Available A laboratory soil degradation study was conducted to determine the biodegradation potential of a DvSnf7 dsRNA transcript derived from a Monsanto genetically modified (GM maize product that confers resistance to corn rootworm (CRW; Diabrotica spp.. This study provides new information to improve the environmental assessment of dsRNAs that become pesticidal through an RNAi process. Three agricultural soils differing in their physicochemical characteristics were obtained from the U.S., Illinois (IL; silt loam, Missouri (MO; loamy sand and North Dakota (ND; clay loam, and exposed to the target dsRNA by incorporating insect-protected maize biomass and purified (in vitro-transcribed DvSnf7 RNA into soil. The GM and control (non-GM maize materials were added to each soil and incubated at ca. 22 °C for 48 hours (h. Samples were collected at 12 time intervals during the incubation period, extracted, and analyzed using QuantiGene molecular analysis and insect bioassay methods. The DT50 (half-life values for DvSnf7 RNA in IL, MO, and ND soils were 19, 28, and 15 h based on QuantiGene, and 18, 29, and 14 h based on insect bioassay, respectively. Furthermore, the DT90 (time to 90% degradation values for DvSnf7 RNA in all three soils were <35 h. These results indicate that DvSnf7 RNA was degraded and biological activity was undetectable within approximately 2 days after application to soil, regardless of texture, pH, clay content and other soil differences. Furthermore, soil-incorporated DvSnf7 RNA was non-detectable in soil after 48 h, as measured by QuantiGene, at levels ranging more than two orders of magnitude (0.3, 1.5, 7.5 and 37.5 µg RNA/g soil. Results from this study indicate that the DvSnf7 dsRNA is unlikely to persist or accumulate in the environment. Furthermore, the rapid degradation of DvSnf7 dsRNA provides a basis to define relevant exposure scenarios for future RNA-based agricultural products.

The objective of the study was to compare the burden and perception of DV among women living in rural and urban Igbo communities of southeast Nigeria. Methods: This was a comparative, cross-sectional study of women residing in rural and urban communities in Enugu, Nigeria, who had gathered for an annual religious meeting from August 1–7, 2011. Data analysis involved descriptive and inferential statistics and was conducted with the Statistical Package for Social Sciences, software version 17.0, at a 95% level of confidence. Results: A total of 836 women who met the eligibility criteria participated in the survey. Of these, 376 were from Okpanku, a rural community, while 460 were from Ogui Nike, an urban community. The prevalence of DV among rural women was significantly higher than that among urban women (97% versus 81%, P<0.001. In particular, the prevalence of physical violence was significantly higher among rural women than among urban women (37.2% versus 23.5%; P=0.05. In contrast, rural and urban women did not differ significantly in the proportions that had experienced psychological or sexual violence. The proportion of women who believed that DV was excusable was significantly higher among rural dwellers than among urban dwellers (58.5% versus 29.6%; P=0.03. Conclusion: The burden of DV against women may be higher in rural

    The C alpha primary hydrogen kinetic isotope effects (C alpha-KIEs) for the reaction of the cytoplasmic isozyme of aspartate aminotransferase (cAATase) with (alpha-2H)-L-aspartate are small and only slightly affected by deuterium oxide solvent (DV = 1.43 +/- 0.03 and DV/KAsp = 1.36 +/- 0.04 in H{sub 2}O; DV = 1.44 +/- 0.01 and DV/KAsp = 1.61 +/- 0.06 in D{sub 2}O). The D{sub 2}O solvent KIEs (SKIEs) are somewhat larger and are essentially independent of deuterium at C alpha (D{sub 2}OV = 2.21 +/- 0.07 and D{sub 2}OV/KAsp = 1.70 +/- 0.03 with ({alpha}-1H)-L-aspartate; D{sub 2}OV = 2.34 +/- 0.12 and D{sub 2}OV/KAsp = 1.82 +/- 0.06 with ({alpha}-2H)-L- aspartate). The C alpha-KIEs on V and on V/KAsp are independent of pH from pH 5.0 to pH 10.0. These results support a rate-determining concerted 1,3 prototropic shift mechanism by the multiple KIE criteria. The large C alpha-KIEs for the reaction of mitochondrial AATase (mAATase) with L-glutamate (DV = 1.88 +/- 0.13 and DV/KGlu = 3.80 +/- 0.43 in H{sub 2}O; DV = 1.57 +/- 0.05 and DV/KGlu = 4.21 +/- 0.19 in D{sub 2}O) coupled with the relatively small SKIEs (D{sub 2}OV = 1.58 +/- 0.04 and D{sub 2}OV/KGlu = 1.25 +/- 0.05 with ({alpha}-1H)-L-glutamate; D{sub 2}OV = 1.46 +/- 0.06 and D{sub 2}OV/KGlu = 1.16 +/- 0.05 with (alpha-2H)-L-glutamate) are most consistent with a two-step mechanism for the 1,3 prototropic shift for this isozyme-substrate pair.

    This study determined whether early experiences by sheep to monotonous or diverse diets influence: (1) plasmatic profiles of cortisol, a hormone involved in stress responses by mammals, before and after an ACTH challenge, (2) the readiness to eat new foods in a new environment, (3) general fearfulness and response to separation--as measured by the open field test (OFT) and stress induced hyperthermia (SIH)--and (4) the link between (2) and (3). Thirty, 2-mo-old lambs were randomly assigned to 3 treatments (10 lambs/treatment). Lambs in one treatment (Diversity--DV) received in successive periods of exposure all possible 4-way choice combinations of 2 foods high in energy and 2 foods high in protein from an array of 6 foods: 3 high in energy (beet pulp, oat grain, and a mix of grape pomace:milo [40:60]) and 3 high in protein (soybean meal, alfalfa, corn gluten meal). Lambs in another treatment (DV+T) received the same exposure described for DV but two phytochemicals, oxalic acid (1.5%) and quebracho tannins (10%) were randomly added within any period of exposure to foods high in energy or to foods high in protein. Lambs in the third treatment (Monotony--MO) received a monotonous balanced ration containing all 6 foods fed to the other groups. After exposure, lambs were offered a choice of the aforementioned 6 foods (DV; DV+T) or the monotonous diet (MO). Lambs were intravenously injected with ACTH 1 h after food presentation, and sampled at 1, 2, and 3 h post feeding for determinations of plasma cortisol concentrations. Reluctance to eat novel flavored foods (onion-, coconut- and cinnamon-flavored wheat bran), open field behavior, and SIH was assessed in all treatments. Lambs in MO showed greater concentrations of plasma cortisol 1 h after food presentation than lambs in the DV or DV+T treatments (P=0.04). However, the difference was small and no differences among treatments were detected after an ACTH challenge (P>0.1). Lambs in DV consumed more onion-flavored wheat

    According to the database from the first paper, we select 180 pairs with dV < 800 km/s and Dp < 60 kpc containing Markarian (MRK) galaxies. We study the dependence of galaxies integral parameters, star-formation (SF) and active galactic nuclei (AGN) properties on kinematics of pairs, their structure and large-scale environments. Following main results were obtained: projected radial separation Dp between galaxies correlates with the perturbation level P of the pairs. Both parameters do not correlate with line-of-sight velocity difference dV of galaxies. Dp and P are better measures of interaction strength than dV. The latter correlates with the density of large-scale environment and with the morphologies of galaxies. Both galaxies in a pair are of the same nature, the only difference is that MRK galaxies are usually brighter than their neighbors in average by 0.9 mag. Specific star formation rates (SSFR) of galaxies in pairs with smaller Dp or dV is in average 0.5 dex higher than that of galaxies in pai...

    water cycle, affected by changes in air mass origin, non-convective and convective processes and continental recycling. Novel remote sensing and in situ measuring techniques have recently offered opportunities for monitoring atmospheric water vapour isotopic composition. Recently developed infrared laser spectrometers allow for continuous in situ measurements of surface water vapour δDv and δ18Ov. So far, very few intercomparisons of measurements conducted using different techniques have been achieved at a given location, due to difficulties intrinsic to the comparison of integrated with local measurements. Nudged simulations conducted with high-resolution isotopically enabled general circulation models (GCMs provide a consistent framework for comparison with the different types of observations. Here, we compare simulations conducted with the ECHAM5-wiso model with two types of water vapour isotopic data obtained during summer 2012 at the forest site of Kourovka, western Siberia: hourly ground-based FTIR total atmospheric columnar δDv amounts, and in situ hourly Picarro δDv measurements. There is an excellent correlation between observed and predicted δDv at surface while the comparison between water column values derived from the model compares well with FTIR estimates.

  20. Nonradiative Electron--Hole Recombination Rate Is Greatly Reduced by Defects in Monolayer Black Phosphorus: Ab Initio Time Domain Study.

    Science.gov (United States)

    Long, Run; Fang, Weihai; Akimov, Alexey V

    2016-02-18

    We report ab initio time-domain simulations of nonradiative electron-hole recombination and electronic dephasing in ideal and defect-containing monolayer black phosphorus (MBP). Our calculations predict that the presence of phosphorus divacancy in MBP (MBP-DV) substantially reduces the nonradiative recombination rate, with time scales on the order of 1.57 ns. The luminescence line width in ideal MBP of 150 meV is 2.5 times larger than MBP-DV at room temperature, and is in excellent agreement with experiment. We find that the electron-hole recombination in ideal MBP is driven by the 450 cm(-1) vibrational mode, whereas the recombination in the MBP-DV system is driven by a broad range of vibrational modes. The reduced electron-phonon coupling and increased bandgap in MBP-DV rationalize slower recombination in this material, suggesting that electron-phonon energy losses in MBP can be minimized by creating suitable defects in semiconductor device material.

  1. Assessing and Enhancing Health Care Providers’ Response to Domestic Violence

    Full Text Available This study aimed to examine possible changes from 2008 to 2012 in the skills of health care staff in identifying and intervening in domestic violence (DV. A longitudinal descriptive study design with volunteer samples (baseline; n=68, follow-up; n=100 was used to acquire information regarding the present state and needs of the staff in practices related to DV. The results of the baseline survey were used as a basis for planning two interventions: staff training and drafting practical guidelines. Information was collected by questionnaires from nurses, physicians, and social workers and supplemented by responses from the interviews. The data were analysed using both quantitative and qualitative methods. A chi-square test was used to test the statistical significance of the data sets. In addition, participants’ quotes are used to describe specific phenomena or issues. The comparison showed that overall a small positive change had taken place between the study periods. However, the participants were aware of their own shortcomings in identifying and intervening in DV. Changes happen slowly, and administrative support is needed to sustain such changes. Therefore, this paper offers recommendations to improve health care providers’ response to DV. Moreover, there is a great need for evaluating the training programme used.

    The decapod Penstyldensovirus 1 (PstDV-1) represents one of the most serious threats for penaeid shrimp farming. Studies aimed at defining relevant molecular effects of this virus over its host are imperative in the attempt to increase our understanding of its pathogenesis. Unfortunately, few studies have focused on the definition of the expression profile of reference genes in shrimp challenged with a pathogen. As a result, there are no studies on the selection of reference genes for the normalization of target gene expression changes yielding reliable data of the effects following PstDV-1 infection in shrimp. Therefore, the aim of the present study was to evaluate and validate the appropriateness of four candidate reference genes (ef1-α, gapdh, rpl8 and β-tubulin) for their use as reference genes to normalize qPCR data in gene expression studies of PstDV-1-shrimp interactions. By analyzing the expression profile of those genes, gapdh was validated as a suitable reference gene to normalize expression data gathered from a PstDV1-challenge, while ef1-α, β-tubulin, and rpl8 were identified as unstably expressed during the infectious process. The suitability of gapdh as a common reference gene in studies of host gene response to viral infections is underlined. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2005-01-01

    Larval dorsoventral (DV) and left-right (LR) axial patterning unfold progressively in sea urchin development, leading to commitment of the major embryonic regions by the gastrula stage. The direct-developing sea urchin Heliocidaris erythrogramma has lost oral-aboral differentiation along the DV axis but has accelerated vestibular ectoderm development on the left side. NiCl(2) radializes indirect-developing sea urchins by shifting cells toward a ventral fate (oral ectoderm). We treated embryos of H. erythrogramma and the indirect-developing H. tuberculata with NiCl(2). H. tuberculata was ventralized exactly like other indirect developers, establishing that basic patterning mechanisms are conserved in this genus. H. erythrogramma was also radialized; timing, dosage response, and some morphological features were similar to those in other sea urchins. Ectodermal explant and recombination experiments demonstrate that the effect of nickel is autonomous to the ectoderm, another feature in common with indirect developers. However, H. erythrogramma is distinctly sinistralized rather than ventralized, its cells shifting toward a left-side fate (vestibular ectoderm). This geometric contrast in the midst of pervasive functional similarity suggests that nickel-sensitive processes in H. erythrogramma axial patterning, homologous to those in indirect developers, have been redeployed, and hence co-opted, from their ancestral role in DV axis determination to a new role in LR axis determination. We discuss DV and LR axial patterning and their evolutionary transformation.

  9. Nodal expression and heterochrony in the evolution of dorsal-ventral and left-right axes formation in the direct-developing sea urchin Heliocidaris erythrogramma.

    2008-12-15

    To understand the role of body axes in the evolution of larval form, we use the two sea urchins in the genus Heliocidaris, which have distinctly different larval morphologies. Heliocidaris tuberculata is an indirect-developing sea urchin, which forms a pluteus larva, whereas its sister species, Heliocidaris erythrogramma, exhibits direct development and forms a nonfeeding, ovoid larva. Changes along all three larval axes underlie the differences in larval form associated with each developmental mode. Nodal signaling has recently been implicated as important in establishing the dorsal-ventral (D-V) and left-right (L-R) axes in the indirect-developing sea urchin Paracentrotus lividus. However, because of changes in morphology and timing of morphogenetic events associated with the D-V and L-R axes, respectively, in H. erythrogramma, it was unclear whether nodal played the same roles during direct development. We show that the expression patterns and functions of nodal during H. erythrogramma development are similar to its roles in indirect-developing sea urchins in both D-V and L-R axes formation. However, there are profound changes in gene expression downstream of nodal signaling along the D-V axis and major heterochronies in the execution of the function of nodal along the L-R axis. These highly modified events are linked to the dramatic modifications of larval morphology that have occurred during the evolution of direct development in H. erythrogramma.

    Violence against women is a global phenomenon that cuts across all social and economic classes. This study was designed to measure the prevalence and correlates of domestic violence (DV) among women seeking services at a voluntary counseling and testing (VCT) center in Bangalore, India. A cross-sectional survey was conducted among women visiting an human immunodeficiency virus (HIV) VCT center in Bangalore, between September and November 2005. An interviewer-administered questionnaire was used to collect information about violence and other variables. Univariable associations with DV were made using Pearson Chi-squared test for categorical variables and Student t-test or the Mann-Whitney test for continuous variables. Forty-two percent of respondents reported DV, including physical abuse (29%), psychological abuse (69%) and sexual abuse (1%). Among the women who reported violence of any kind, 67% also reported that they were HIV seropositive. The most common reasons reported for DV included financial problems (38%), husband's alcohol use (29%) and woman's HIV status (18%). Older women (P women suffering from domestic partner violence.

  19. Children's experiences of domestic violence and abuse: Siblings' accounts of relational coping.

    Science.gov (United States)

    Callaghan, Jane E M; Alexander, Joanne H; Sixsmith, Judith; Fellin, Lisa C

    2016-10-01

    This article explores how children see their relationships, particularly their sibling relationships, in families affected by domestic violence (DV) and how relationality emerges in their accounts as a resource to build an agentic sense of self. The 'voice' of children is largely absent from the DV literature, which typically portrays them as passive, damaged and relationally incompetent. Children's own understandings of their relational worlds are often overlooked, and consequently, existing models of children's social interactions give inadequate accounts of their meaning-making-in-context. Drawn from a larger study of children's experiences of DV and abuse, this article uses two case studies of sibling relationships to explore young people's use of relational resources, for coping with violence in the home. The article explores how relationality and coping intertwine in young people's accounts and disrupts the taken-for-granted assumption that children's 'premature caring' or 'parentification' is (only) pathological in children's responses to DV. This has implications for understanding young people's experiences in the present and supporting their capacity for relationship building in the future.

    In 2013, the Dutch Government mandated a new policy stating that all healthcare professionals caring for adults in difficult psychosocial situations should always investigate the safety of any children involved. We describe two cases of such 'child checks' in the accident and emergency department (A&E). Patient A, a 10-year-old girl, was referred to the outpatient paediatric department (OPD) after her mother had attended the A&E as a victim of domestic violence (DV). The child had witnessed DV on multiple occasions. The family were referred to voluntary social and psychiatric healthcare. Patient B, a 46 year-old woman, attended the A&E with serious injuries, and said she had tripped over. The A&E physician suspected that the injuries were caused by DV, and the mother and her 9-year-old daughter were referred to the OPD. However, the mother refused to attend, and the family was reported to the Youth Care Office. Because parents' psychosocial problems, such as DV, can seriously affect children, their safety should always be investigated by performing a 'child check'.

    The performance of the novel ''ductless'' personalized ventilation in conjunction with displacement ventilation (DV) was compared with the performance of DV alone under realistic conditions involving disturbances due to walking of one or two persons. An office room with two workstations was arranged in a full-scale test room. Two thermal manikins were used as sedentary occupants at the workstations. Two pollution sources, namely exhaled air by one of the manikins and passive pollution on the table in front of the same manikin were simulated. The performance of the ventilation systems was evaluated with regard to the quality of inhaled air and thermal comfort of the seated ''occupants''. The walking person(s) caused mixing of the clean and cool air near the floor with the polluted and warmer air at higher levels and disturbed the displacement principle which resulted in a decrease of the inhaled air quality. The performance of the ''ductless'' PV under the tested conditions was better as opposed to DV alone. Thus in practice the ''ductless'' PV will be superior to DV alone as regards perceived quality of inhaled air. The location of a walking person was found to be important. Person(s) walking close to the displacement diffuser will cause greater disturbance. (author)

    Design guidelines envisage that floor heating can be used together with displacement ventilation (DV), provided that the supply air is not overly heated before it can reach heat and contaminant sources. If this is not controlled a mixing flow pattern could occur in the room. The use of floor cooling with DV is also considered possible, although draught risk at ankle level and vertical air temperature differences must be controlled carefully, because they could increase. Few studies on these topics were found in the literature. An indoor environmental chamber was set up to obtain measurements aimed at analysing the possibilities and limitations of combining floor heating/cooling with DV. Air temperature profiles, air velocity profiles, surface temperatures and ventilation effectiveness were measured under different environmental conditions that may occur in practice. These values were compared to equivalent temperature measurements obtained using a thermal manikin. The measurements show that floor heating can be used with DV, obtaining high ventilation effectiveness values. A correlation between the floor heating capacity and the air temperature profile in the room was found. Measurements showed that floor cooling does not increase draught risk at ankle level, although it does increase vertical air temperature differences. (author)

    Personalized ventilation (PV) system in conjunction with total ventilation system can provide cleaner inhaled air for the user. Concerns still exist about whether the normally protecting PV device, on the other hand, facilitates the dispersion of infectious agents generated by its user. In this article, two types of PV systems with upward supplied fresh air, namely a chair-based PV and one kind of desk-mounted PV systems, when combined with mixing ventilation (MV) and displacement ventilation (DV) systems, are investigated using simulation method with regard to their impacts on co-occupant's exposure to the exhaled droplet nuclei generated by the infected PV user. Simulation results of tracer gas and particles with aerodynamic diameter of 1, 5, and 10 μm from exhaled air show that, when only the infected person uses a PV, the different PV air supplying directions present very different impacts on the co-occupant's intake under DV, while no apparent differences can be observed under MV. The findings demonstrate that better inhaled air quality can always be achieved under DV when the adopted PV system can deliver conditioned fresh air in the same direction with the mainly upward airflow patterns of DV.

    While the majority of research on dating violence (DV) and sexual assault (SA) in college students has focused on heterosexual students, victimization rates among sexual minority students are the same or higher than that of their heterosexual counterparts. The current study sought to explore sexual minority college students' perceptions of the prevalence of DV and SA, risk and protective factors, and barriers to seeking help, using focus groups. A total of 14 sexual minority students ranging in age from 18 to 24 participated across 2 focus groups. Findings suggest the majority of the students perceived DV and SA among sexual minority individuals to be less common compared to their heterosexual counterparts and to be less common on their campus compared to other colleges and universities. Students' reflections about risk and protective factors overlapped with those previously established among heterosexuals as well as factors unique to the sexual minority community. Students identified societal, community, and psychological-level barriers related to help-seeking. We provide recommendations for practice based on the current findings (e.g., colleges could expand current educational material about DV and SA to include more recognition of these issues for sexual minority students).

    Lehrer, Jocelyn A; Lehrer, Evelyn L; Koss, Mary P

    2013-01-01

    This paper synthesises and discusses results from the 2005 Survey of Student Well-Being, a closed-ended questionnaire administered to students attending general education courses at a major public university in Santiago (n = 484 women, 466 men). The survey included questions on sexual violence (SV) and dating violence (DV), public health problems that have received little attention in Chile and other Latin-American countries. This paper highlights key findings from a series of papers based on these data, noting lessons learned in the Chilean context that may be useful for other Latin-American countries. Important gaps in the international literature on SV and DV are also discussed. A central finding is the high prevalence of SV and DV in this sample of university students, warranting further public health attention to these problems. Potentially, the findings will contribute to changes in awareness, policy and practice along similar lines to efforts that transformed the US landscape regarding SV and DV on college campuses in the 1980s.

    Previous studies have demonstrated that petal shape and size in legume flowers are determined by two separate mechanisms,dorsoventral (DV) and organ internal (IN) asymmetric mechanisms,respectively.However,little is known about the molecular mechanisms controlling petal development in legumes.To address this question,we investigated petal development along the floral DV axis in Lotus japonicus with respect to cell and developmental biology by comparing wild-type legumes to mutants.Based on morphological markers,the entire course of petal development,from initiation to maturity,was grouped to define 3 phases or 13 stages.In terms of epidermal micromorphology from adaxial surface,mature petals were divided into several distinct domains,and characteristic epidermal cells of each petal differentiated at stage 9,while epidermal cells of all domains were observed until stage 12.TCP and MIXTA-like genes were found to be differentially expressed in various domains of petals at stages 9 and 12.Our results suggest that DV and IN mechanisms interplay at different stages of petal development,and their interaction at the cellular and molecular level guides the elaboration of domains within petals to achieve their ideal shape,and further suggest that TCP genes determine petal identity along the DV axis by regulating MIXTA-like gene expression.

    2014-01-01

    Full Text Available Background. During dengue virus (DV infection, monocytes produce tumor necrosis factor alpha (TNF-α and nitric oxide (NO which might be critical to immunopathogenesis. Since intensity of DV replication may determine clinical outcomes, it is important to know the effects of viral nonstructural protein 1 (NS1 on innate immune parameters of infected patients. The present study investigates the relationships between dengue virus nonstructural protein 1 (NS1 serum levels and innate immune response (TLR4 expression and TNF-α/NO production of DV infected patients presenting different clinical outcomes. Methodology/Principal Findings. We evaluated NO, NS1 serum levels (ELISA, TNF-α production by peripheral blood mononuclear cells (PBMCs, and TLR4 expression on CD14+ cells from 37 dengue patients and 20 healthy controls. Early in infection, increased expression of TLR4 in monocytes of patients with dengue fever (DF was detected compared to patients with dengue hemorrhagic fever (DHF. Moreover, PBMCs of DHF patients showed higher NS1 and lower NO serum levels during the acute febrile phase and a reduced response to TLR4 stimulation by LPS (with a reduced TNF-α production when compared to DF patients. Conclusions/Significance. During DV infection in humans, some innate immune parameters change, depending on the NS1 serum levels, and phase and severity of the disease which may contribute to development of different clinical outcomes.

  11. Co-ordination in morphological leaf traits of early diverging angiosperms is maintained following exposure to experimental palaeo-atmospheric conditions of sub-ambient O2 and elevated CO2

    Directory of Open Access Journals (Sweden)

    2016-09-01

    Full Text Available In order to be successful in a given environment a plant should invest in a vein network and stomatal distribution that ensures balance between both water supply and demand. Vein density (Dv and stomatal density (SD have been shown to be strongly positively correlated in response to a range of environmental variables in more recently evolved plant species, but the extent of this relationship has not been confirmed in earlier diverging plant lineages. In order to examine the effect of a changing atmosphere on the relationship between Dv and SD, five early-diverging plant species representing two different reproductive plant grades were grown for seven months in a palaeo-treatment comprising an O2:CO2 ratio that has occurred multiple times throughout plant evolutionary history. Results show a range of species-specific Dv and SD responses to the palaeo-treatment, however we show that the strong relationship between Dv and SD under modern ambient atmospheric composition is maintained following exposure to the palaeo-treatment. This suggests strong inter-specific co-ordination between vein and stomatal traits for our study species even under relatively extreme environmental change. This co-ordination supports existing plant function proxies that use the distance between vein endings and stomata (Dm to infer plant palaeo-physiology.

    To examine the performance of screening for trisomies 21, 18 and 13 at 11-13 weeks' gestation using specific algorithms for these trisomies based on combinations of fetal nuchal translucency thickness (NT), fetal heart rate (FHR), ductus venosus pulsatility index for veins (DV PIV), and serum free β-human chorionic gonadotropin (β-hCG), pregnancy-associated plasma protein A (PAPP-A), placental growth factor (PLGF) and α-fetoprotein (AFP). Model-based estimates of screening performance were produced for the distribution of maternal ages in England and Wales in 2011, and prospectively collected data on fetal NT, FHR, DV PIV, β-hCG, PAPP-A, PLGF and AFP from singleton pregnancies undergoing aneuploidy screening. In screening by NT, FHR, free β-hCG and PAPP-A, using specific algorithms for trisomy 21 and trisomies 18 and 13 at the risk cutoff of 1:100, the estimated detection rate (DR) was 87.0% for trisomy 21 and 91.8% for trisomies 18 and 13, at a false-positive rate (FPR) of 2.2%. Addition of PLGF, AFP and DV PIV increased the DR to 93.3% for trisomy 21 and 95.4% for trisomies 18 and 13 and reduced the FPR to 1.3%. Effective screening for trisomies can be achieved using specific algorithms based on NT, FHR, DV PIV, β-hCG, PAPP-A, PLGF and AFP. © 2013 S. Karger AG, Basel.

    The adsorption of CO2 and H2O on divacanacy (DV) defected graphene cluster, and its bilayer counterpart is investigated using first-principles calculations. Both single and bilayer DV graphene cluster, are functionalised with H and F atoms. On these sheets the gas molecules are physisorbed, and the divacancy defect effectively improves the adsorption of CO2, while fluorination enhances the hydrophobicity of the graphene cluster. Among the convex and concave curvature regions induced due to the DV defect, the adsorption of the gas molecules on the concave meniscus is more favourable. Fluorine termination induces 73% reduction in Henry law constants for H2O, while for the CO2 molecule it increases by 8%, which indicates the DV defective sheet is a better candidate for CO2 capture compared to the STW defective sheet. Besides, both AA and AB divacant defect bilayer sheets are equally stable, wherein AA stacking results in a cavity between the sheets, while in AB stacking, the layers slide one over the other. Nevertheless, both these bilayer sheets are comparatively stabler than the monolayer. However, intercalation of lithium decreases the interlayer separation, particularly in AA stacking, which enhances the CO2 adsorption, but in the Bernal stacking enhances it hydrophobicity.

    1997-08-01

    A confidential written survey was conducted at the emergency department (ED) of Charity Hospital in New Orleans to determine the prevalence of domestic violence (DV) for male and female ED patients and to determine the demographics of DV. Four violence parameters were calculated for patients who had a partner at the time of presentation: 1) present physical; 2) present nonphysical; 3) past physical; and 4) past nonphysical. Out of the 516 patients enrolled, 283 were women and 233 were men. On the basis of Index of Spouse Abuse scoring, 14% of men and 22% of women had experienced past nonphysical violence, and 28% of men and 33% of women had experienced past physical violence. Of the 157 men and 207 women with partners at the time of presentation, 11% men and 15% women reported present nonphysical violence, and 20% men and 19% of the women reported present physical violence. Logistic-regression models demonstrated that women experienced significantly more past and present nonphysical violence but not physical violence than men. Alcohol, drug use, and suicidal ideation were found to be significant predictors associated with DV. In conclusion, DV rates were high in the New Orleans population, with nearly equal rates of past and present physical violence for men and women.

    The purpose of this study is to evaluate the preliminary efficacy of a dating violence (DV) prevention program for Cuban American adolescents (JOVEN/YOUTH: Juntos Opuestos a la Violence Entre Novios/Together Against Dating Violence). A randomized-controlled experimental design with a delayed condition was used to evaluate the effects on DV victimization and perpetration (N = 82). Self-administrated assessments were completed at baseline, 1 week, 3 months, and 12 months after the intervention to assess for psychological victimization and perpetration and physical and sexual victimization and perpetration. Effect sizes were estimated, and generalized estimating equations were generated to test intervention effects over time and potential gender interactions. The intervention had medium to strong effects on DV victimization and perpetration for male participants but not for females. However, intervention effects were not statistically significant over time. More research is needed to enhance intervention effects of JOVEN on DV outcomes and to evaluate these effects among a larger and more diverse sample. PMID:26260135

    Full Text Available In order to demonstrate the influence of fire disturbance on the function, structure and seasonal dynamics of ground-dwelling spider assemblages, we chose a burned site and an unburned control site. Both study sites were in broadleaf-conifer mixed forest on Cangshan Mountain, Yunnan Province. The results showed that (1 Zelotes zhui (relative dominance value (DV' =33.03, Pardosa chionophila (DV'=22.53 and Sibianor sp. 1 (DV'=8.75 were obviously dominant at the burned site and that Draconarius sp. 2 (DV'=63.50 was absolutely dominant at the control site; (2 At the burned site, the relative abundance of web-builders was significantly lower than that of hunters (P<0.001, whereas the relative abundance of web-builders was significantly higher than that of hunters at the control site; and (3 As season changed, the dominant group fluctuated significantly at the burned, with the lowest abundance during the part of the summer with the maximum rainfall and during the coldest winter; the spider assemblages were stable at the control site, with agelenids consistently the dominant group. These results indicated that fire disturbance changes the community function and structure of ground-dwelling spiders in mixed broadleaf-conifer forest in Cangshan Mountain, increases the relative abundance of hunters and reduces the stability of ground-dwelling spider assemblages.

  17. Metallicities and dust content of proximate damped Lyman alpha systems in the Sloan Digital Sky Survey

    Ellison, Sara L; Mendel, J Trevor

    2010-01-01

    Composite spectra of 85 proximate absorbers (log N(HI)>20 and velocity difference between the absorption and emission redshift, dv6000 km/s, with further sub-samples to investigate the metal line dependence on N(HI) and QSO luminosity. Low (e.g. SiII and FeII) and high ionization (e.g. SiIV and CIV) species alike have equivalent widths (EWs) that are larger by factors of 1.5 -- 3 in the dv6000 km/s spectrum. The EWs show an even stronger dependence on dv if only the highest neutral hydrogen column density (log N(HI)>20.7) absorbers are considered. We conclude that PDLAs generally have higher metallicities than intervening absorbers, with the enhancement being a function of both dv and N(HI). It is also found that absorbers near QSOs with lower rest-frame UV luminosities have significantly stronger metal lines. We speculate that absorbers near to high luminosity QSOs may have had their star formation prematurely quenched. Finally, we search for the signature of dust reddening by the PDLAs, based on an analysis...

    2010-07-01

    We have developed a new type of television named FTV (Free-viewpoint TV). FTV is the ultimate 3DTV that enables us to view a 3D scene by freely changing our viewpoints. We proposed the concept of FTV and constructed the world's first real-time system including the complete chain of operation from image capture to display. FTV is based on the rayspace method that represents one ray in real space with one point in the ray-space. We have developed ray capture, processing and display technologies for FTV. FTV can be carried out today in real time on a single PC or on a mobile player. We also realized FTV with free listening-point audio. The international standardization of FTV has been conducted in MPEG. The first phase of FTV was MVC (Multi-view Video Coding) and the second phase is 3DV (3D Video). MVC was completed in May 2009. The Blu-ray 3D specification has adopted MVC for compression. 3DV is a standard that targets serving a variety of 3D displays. The view generation function of FTV is used to decouple capture and display in 3DV. FDU (FTV Data Unit) is proposed as a data format for 3DV. FTU can compensate errors of the synthesized views caused by depth error.

    Let the function $f: \\bar{\\R}^2_+ \\to \\C$ be such that $f\\in L^1_{\\loc} (\\bar{\\R}^2_+)$. We investigate the convergence behavior of the double integral $$\\int^A_0 \\int^B_0 f(u,v) du dv \\quad {\\rm as} \\quad A,B \\to \\infty,\\leqno(*)$$ where $A$ and $B$ tend to infinity independently of one another; while using two notions of convergence: that in Pringsheim's sense and that in the regular sense.

  5. A coleopteran cadherin fragment synergizes toxicity of Bacillus thuringiensis toxins Cry3Aa, Cry3Bb, and Cry8Ca against lesser mealworm, Alphitobius diaperinus (Coleoptera: Tenebrionidae).

    2014-11-01

    The lesser mealworm, Alphitobius diaperinus, is a serious cosmopolitan pest of commercial poultry facilities because of its involvement in structural damage to poultry houses, reduction in feed conversion efficiency, and transfer of avian and human pathogens. Cry3Aa, Cry3Bb, and Cry8Ca insecticidal proteins of Bacillus thuringiensis are used to control coleopteran larvae. Cadherins localized in the midgut epithelium function as receptors for Cry toxins in lepidopteran, coleopteran, and dipteran insects. Previously, we demonstrated that the truncated cadherin (DvCad1) from Diabrotica virgifera virgifera, which consists of the C-terminal cadherin repeats (CR) 8-10 and expressed in Escherichia coli, enhanced Cry3Aa and Cry3Bb toxicity against several coleopteran species. Here we report that the DvCad1-CR8-10 enhances Cry3Aa, Cry3Bb, and Cry8Ca toxicity to lesser mealworm. Previously, by an enzyme linked immunosorbent microplate assay, we demonstrated that the DvCad1-CR8-10 binds activated-Cry3Aa (11.8 nM), -Cry3Bb (1.4nM), and now report that CR8-10 binds activated-Cry8Ca (5.7 nM) toxin. The extent of Cry toxins enhancement by DvCad1-CR8-10, which ranged from 3.30- to 5.93-fold, may have practical application for lesser mealworm control in preventing avian and human pathogen transfer in poultry facilities.

  10. The maternal JAK/STAT pathway of Drosophila regulates embryonic dorsal-ventral patterning

    Directory of Open Access Journals (Sweden)

    Lopes E.S.S.

    2004-01-01

    Full Text Available Activation of NFkappaB plays a pivotal role in many cellular processes such as inflammation, proliferation and apoptosis. In Drosophila, nuclear translocation of the NFkappaB-related transcription factor Dorsal is spatially regulated in order to subdivide the embryo into three primary dorsal-ventral (DV domains: the ventral presumptive mesoderm, the lateral neuroectoderm and the dorsal ectoderm. Ventral activation of the Toll receptor induces degradation of the IkappaB-related inhibitor Cactus, liberating Dorsal for nuclear translocation. In addition, other pathways have been suggested to regulate Dorsal. Signaling through the maternal BMP member Decapentaplegic (Dpp inhibits Dorsal translocation along a pathway parallel to and independent of Toll. In the present study, we show for the first time that the maternal JAK/STAT pathway also regulates embryonic DV patterning. Null alleles of loci coding for elements of the JAK/STAT pathway, hopscotch (hop, marelle (mrl and zimp (zimp, modify zygotic expression along the DV axis. Genetic analysis suggests that the JAK kinase Hop, most similar to vertebrate JAK2, may modify signals downstream of Dpp. In addition, an activated form of Hop results in increased levels of Cactus and Dorsal proteins, modifying the Dorsal/Cactus ratio and consequently DV patterning. These results indicate that different maternal signals mediated by the Toll, BMP and JAK/STAT pathways may converge to regulate NFkappaB activity in Drosophila.

  11. Differential distribution improves gene selection stability and has competitive classification performance for patient survival.

    Science.gov (United States)

    Strbenac, Dario; Mann, Graham J; Yang, Jean Y H; Ormerod, John T

    2016-07-27

    A consistent difference in average expression level, often referred to as differential expression (DE), has long been used to identify genes useful for classification. However, recent cancer studies have shown that when transcription factors or epigenetic signals become deregulated, a change in expression variability (DV) of target genes is frequently observed. This suggests that assessing the importance of genes by either differential expression or variability alone potentially misses sets of important biomarkers that could lead to improved predictions and treatments. Here, we describe a new approach for assessing the importance of genes based on differential distribution (DD), which combines information from differential expression and differential variability into a unified metric. We show that feature ranking and selection stability based on DD can perform two to three times better than DE or DV alone, and that DD yields equivalent error rates to DE and DV. Finally, assessing genes via differential distribution produces a complementary set of selected genes to DE and DV, potentially opening up new categories of biomarkers.

MÉTODO: Prontidão para extubação foi determinada usando os critérios propostos pela 6ª Conferência Internacional de Consenso em Medicina Intensiva adaptados a crianças. RESULTADOS: A ventilação não invasiva (VNI foi usada em quatro pacientes que desenvolveram insuficiência respiratória após a extubação; nenhum foi reintubado. Crianças que precisaram de VNI para evitar a reintubação tiveram razão V D/V T significativamente maior do que as que foram extubadas sem VNI (p < 0,001. O valor de corte da razão V D/V T foi 0,55, e a área sob a curva ROC foi 0,86. CONCLUSÃO: Nossos achados confirmam o bom valor preditivo do sucesso/fracasso do desmame pela razão V D/V T e sugere seu papel como preditor da necessidade de VNI após extubação.

    2016-01-01

    In order to be successful in a given environment a plant should invest in a vein network and stomatal distribution that ensures balance between both water supply and demand. Vein density (Dv) and stomatal density (SD) have been shown to be strongly positively correlated in response to a range of environmental variables in more recently evolved plant species, but the extent of this relationship has not been confirmed in earlier diverging plant lineages. In order to examine the effect of a changing atmosphere on the relationship between Dv and SD, five early-diverging plant species representing two different reproductive plant grades were grown for 7 months in a palaeo-treatment comprising an O2:CO2 ratio that has occurred multiple times throughout plant evolutionary history. Results show a range of species-specific Dv and SD responses to the palaeo-treatment, however, we show that the strong relationship between Dv and SD under modern ambient atmospheric composition is maintained following exposure to the palaeo-treatment. This suggests strong inter-specific co-ordination between vein and stomatal traits for our study species even under relatively extreme environmental change. This co-ordination supports existing plant function proxies that use the distance between vein endings and stomata (Dm) to infer plant palaeo-physiology. PMID:27695464

    2006-10-12

    The response of Desulfovibrio vulgaris Hildenborough (DvH),a sulphate-reducing bacterium, to nitrate stress was examined usingquantitative proteomic analysis. DvH was stressed with 105 m M sodiumnitrate(NaNO3), a level that caused a 50 percent inhibition in growth.The protein profile of stressed cells was compared with that of cellsgrown in the absence of nitrate using the iTRAQ peptide labellingstrategy and tandem liquid chromatography separation coupled with massspectrometry (quadrupoletime-of-flight) detection. A total of 737 uniqueproteins were identified by two or more peptides, representing 22 percentof the total DvH proteome and spanning every functional category. Theresults indicate that this was a mild stress, as proteins involved incentral metabolism and the sulphate reduction pathway were unperturbed.Proteins involved in the nitrate reduction pathway increased. Increasesseen in transport systems for proline, glycine^ betaineandglutamateindicate that the NaNO3 exposure led to both salt stress and nitratestress.Up-regulation observed in oxidative stress response proteins (Rbr,RbO, etc.) and a large number of ABC transport systems as well as in iron^ sulphur -cluster-containing proteins, however, appear to be specific tonitrate exposure. Finally, a number of hypothetical proteins were amongthe most significant changers, indicating that there may be unknownmechanisms initiated upon nitrate stress in DvH.

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Dating violence (DV is now recognized as an important public health issue. Prevention and intervention programs are being implemented in school contexts. Such initiatives aim to raise awareness among potential victims and offenders as well as among peer bystanders and offer adequate interventions following disclosure. Yet, a major challenge remains as teenagers may not disclose their victimization or may not feel self-efficient to deal with DV if they witness such violence. As such, teen DV remains largely hidden. A representative sample of 8194 students (age 14-18 in the province of Quebec, Canada was used to explore teenagers’ self-efficacy to reach out for help or to help others in a situation of DV victimization and perpetration. Analyses are conducted to identify possible correlates of self-efficacy in terms of socio-demographic variable (sex, age and a history of child sexual abuse and dating victimization. Implications for preven­tion and support strategies are discussed.

    Darling, Jeremy

    2012-01-01

    We present precise HI 21 cm absorption line redshifts observed in multiple epochs to directly constrain the secular redshift drift dz/dt_o or the cosmic acceleration, dv/dt_o. A comparison of literature analog spectra to contemporary digital spectra shows significant acceleration likely attributable to systematic instrumental errors. However, we obtain robust constraints using primarily Green Bank Telescope digital data. Ten objects spanning z=0.09-0.69 observed over 13.5 years show dz/dt_o = (-2.3 +/- 0.8) x 10^-8 yr^-1 or dv/dt_o = -5.5 +/- 2.2 m/s/yr. The best constraint from a single object, 3C286 at = 0.692153275(85), is dz/dt_o = (1.6 +/- 4.7) x 10^-8 yr^-1 or dv/dt_o =2.8 +/- 8.4 m/s/yr. These measurements are three orders of magnitude larger than the theoretically expected acceleration at z=0.5, dz/dt_o = 2 x 10^-11 yr^-1 or dv/dt_o = 0.3 cm/s/yr, but they demonstrate the lack of peculiar acceleration in absorption line systems and the long-term frequency stability of modern radio telescopes.

    目的 了解原核表达的登革病毒(dengue virus, DV)的E蛋白结构域Ⅲ直接抑制登革病毒感染及其抗体的中和作用.方法 在大肠埃希菌中表达1~4型登革病毒E蛋白结构域Ⅲ(EⅢ).重组蛋白纯化后,进行阻断DV-2感染BHK~21细胞试验.用重组蛋白制备免疫血清,检测抗体中和作用.结果 在大肠埃希菌中成功表达了1-4型登革病毒E蛋白结构域埃希菌,4型重组E蛋白结构域Ⅲ均能够阻断2型DV感染,4型重组蛋白的免疫血清均能中和2型DV,但中和抗体效价不同.结论 原核表达的登革病毒结构域Ⅲ可以直接抑制病毒感染,所产生的抗体具有中和作用.直接抑制和中和抗体均对同型病毒作用较强.%Objective To observe the ability of dengue virus recombinant envelope protein domain expressed in E. coil to inhibit virus infection and induce the neutralizing antibody. Methods E Ⅲ protein of Dengue virus serotypes 1-4 were expressed in E. coli BL21 (DE3) then purified. Recombinant proteins were tested to inhibit DV2 from infecting BHK-21 cell. Rabbits were immunized with recombinant proteins to produce anti-E Ⅲserum. Antibody titers were determined by neutralizing assay. Results The recombinant E Ⅲ proteins of Dengue virus serotypes 1-4 were expressed in E. coli. They effectively protected BHK cells in culture against DV2infection. All four type anti-E Ⅲ sera can neutralize DV2 but their efficacies are different. Conclusion E Ⅲproteins of dengue virus expressed in E. coli can directly inhibit DV2 infection. Neutralizing antibodies were induced by E Ⅲ proteins. Both E Ⅲ protein of dengue virus and the neutralizing antibodies they induced are more efficient in inhibiting homologous dengue serotypes infection than heterologous serotypes.

    Full Text Available The objective of this work was to evaluate the sympathetic nervous system and structure remodeling during the progression of heart failure in a rodent model using dynamic cardiac single-photon emission computed tomography (SPECT. The spontaneously hypertensive rat (SHR model was used to study changes in the nervous system innervation and perfusion in the left ventricular (LV myocardium with the progression of left ventricular hypertrophy (LVH to heart failure. Longitudinal dynamic SPECT studies were performed with seven SHR and seven Wistar-Kyoto (WKY rats over 1.5 years using a dual-head SPECT scanner with pinhole collimators. Time-activity curves (TACs of the 123I-MIBG and 201Tl distribution in the LV blood pool and myocardium were extracted from dynamic SPECT data and fitted to compartment models to determine the influx rate, washout rate, and distribution volume (DV of 123I-MIBG and 201Tl in the LV myocardium. The standardized uptake values (SUVs of 123I-MIBG and 201Tl in the LV myocardium were also calculated from the static reconstructed images. The influx and washout rates of 123I-MIBG did not show a significant difference between SHRs and WKY rats. The DVs of 123I-MIBG were greater in the SHRs than in the WKY rats (p = .0028. Specifically, the DV of 123I-MIBG became greater in the SHRs by 6 months of age (p = .0017 and was still significant at the age of 22 months. The SUV of 123I-MIBG in SHRs exhibited abnormal values compared to WKY rats from the age of 18 months. There was no difference in the influx rate and the washout rate of 201Tl between the SHRs and WKY rats. The SHRs exhibited greater DV of 201Tl than WKY rats after the age of 18 months (p = .034. The SUV of 201Tl in SHRs did not show any significant difference from WKY at all ages. The higher DV of 123I-MIBG in the LV myocardium reveals abnormal nervous system activity of the SHRs at an age of 6 months, whereas a greater DV of 201Tl in the LV myocardium can only be detected at

    2008-06-01

    Full Text Available The purpose of this study was to analyze the relationship between the intra-cycle variation of the horizontal velocity of displacement of the center of mass (dV, the hand's and feet's velocity, as well as, to identify the variables that most predict the dV's, in butterfly stroke. The study was divided in two parts. The aim of Part I was to investigate the behavior of variables in study at slow swimming velocities and the purpose of Part II was the same but at high swimming velocities. 3 male Portuguese swimmers and 1 female swimmer, of international level were studied in Part I. The swimmers were submitted to an incremental set of 200 m butterfly swims. In the Part II, 7 Portuguese male swimmers of national and international level were studied. Each swimmer performed two maximal 25 m butterfly swims. Both protocols were recorded from four different plans, allowing a 3D analysis. It was calculated the dV, the 3D components (Vx, Vy, Vz of the hand's velocity and the 2D components (Vx, Vy of the feet's velocity. Several variables presented significant correlation coefficients with dV at all selected velocities (high velocity ranged from r = 0.58 for Vx-out to r = 0.82 for Vy-1dwn; slow velocity ranged from r = -0.45 for Vx-1dwn to r=0.73 for Vx-ups; overall velocity ranged from r= 0.34 for Vz-ent to r = 0.82 for Vx-ins. It was also computed a regression model to predict dV. For high velocity (up to 1.75 ± 0.09 m.s-1, the variables that best predict dV were Vy during the first downbeat, Vx and Vy during the arm's insweep (r2 = 0.93. At slow velocity (up to 1.48 m.s-1, the variables included in the forward step-by-step regression model were Vx during upsweep, Vy and Vx during insweep (r2 = 0.69. For overall velocity, the variables that most fit the regression model were Vx during upsweep, Vy during second downbeat and Vz during entry (r2= 0.94. In order to reduce dV, butterfliers should increase hand's velocity in all orthogonal components at the

    Full Text Available Problem: Even though reforms in the past 40 years mandated police response to domestic violence (DV crime, and in many states also mandated arrest, never-the-less baseline rates of DV prosecution remain low. Background: The nature of prosecution is reviewed, noting that nearly all criminal cases are resolved through plea bargaining in state and federal cases. Thus, the nature of plea bargaining is examined from a perspective of negotiable currency. Past research demonstrates that if multiple crimes are described and listed in the first responding police officer’s written report, there is a substantially greater odds that the suspect will be prosecuted and found guilty. Those extra charges can be dropped by prosecutors in exchange for a plea of guilt. Purpose: This empirical study examines a discretionary best practices crime investigation method that can be operationalized by first responding police officers, in situ, to determine whether its use leads to a significant increase in rates of prosecution and criminal conviction for DV crime. The methodology is the choice to thoroughly investigate each DV crime to uncover concurrent and also past-but-still-chargeable crimes. This optional work is time-consuming because children, neighbors, the 911 caller, and others must be contacted and interviewed. Method: Randomly selected police reports (n = 366 were found to contain 22 combinations of crime codes listed as violations, for DV and other concurrent crimes. The reports were evaluated on a number of prosecutorial outcomes. Frequency statistics were calculated, and logistic regression was used to confirm key relationships. Results: Only one third of all submitted reports listed more than one crime. For those investigations that did lead to prosecution, 97% resolved through plea bargaining. Most single charge misdemeanor DV police reports were found to be “dead upon arrival” at the prosecutor’s office, with only 29% resulting in any type of

ConclusionDomestic violence is common in Yangzhou,especially mental violence,and the youth and middleaged women with low education are at higher risk for DV.

  14. Microbial community composition of transiently wetted Antarctic Dry Valley soils

    Full Text Available During the summer months, wet (hyporheic soils associated with ephemeral streams and lake edges in the Antarctic Dry Valleys (DV become hotspots of biological activity and are hypothesized to be an important source of carbon and nitrogen for arid DV soils. Recent research in the DV has focused on the geochemistry and microbial ecology of lakes and arid soils, with substantially less information being available on hyporheic soils. Here we determined the unique properties of hyporheic microbial communities, resolved their relationship to environmental parameters and to compared them to archetypal arid DV soils. Generally, pH increased and chlorophyll a concentrations decreased along transects from wet to arid soils (9.0 to ~7.0 for pH and ~0.8 to ~ 5 µg/cm3 for chlorophyll a, respectively. Soil water content decreased to below ~3% in the arid soils. Community fingerprinting-based principle component analyses revealed that bacterial communities formed distinct clusters specific to arid and wet soils; however, eukaryotic communities that clustered together did not have similar soil moisture content nor did they group together based on sampling location. Collectively, rRNA pyrosequencing indicated a considerably higher abundance of Cyanobacteria in wet soils and a higher abundance of Acidobacterial, Actinobacterial, Deinococcus/Thermus, Bacteroidetes, Firmicutes, Gemmatimonadetes, Nitrospira and Planctomycetes in arid soils. The two most significant differences at the genus level were Gillisia signatures present in arid soils and chloroplast signatures related to Streptophyta that were common in wet soils. Fungal dominance was observed in arid soils and Viridplantae were more common in wet soils. This research represents an in-depth characterization of microbial communities inhabiting wet DV soils. Results indicate that the repeated wetting of hyporheic zones has a profound impact on the bacterial and eukaryotic communities inhabiting in these areas.

    There is a growing interest in achieving higher survival rates with the lowest morbidity in localized prostate cancer (PC) treatment. Consequently, minimally invasive techniques such as low-dose rate brachytherapy (BT) and robotic-assisted prostatectomy (RALP) have been developed and improved. Comparative analysis of functional outcomes and quality of life in a prospective series of 51BT and 42Da Vinci prostatectomies DV Materials and Methods: Comparative analysis of functional outcomes and quality of life in a prospective series of 93 patients with low-risk localized PC diagnosed in 2011. 51patients underwent low-dose rate BT and the other 42 patients RALP. IIEF to assess erectile function, ICIQ to evaluate continence and SF36 test to quality of life wee employed. ICIQ at the first revision shows significant differences which favour the BT group, 79% present with continence or mild incontinence, whereas in the DV group 45% show these positive results. Differences disappear after 6 months, with 45 patients (89%) presenting with continence or mild incontinence in the BT group vs. 30 (71%) in the DV group. 65% of patients are potent in the first revision following BT and 39% following DV. Such differences are not significant and cannot be observed after 6 months. No significant differences were found in the comparative analysis of quality of life. ICIQ after surgery shows significant differences in favour of BT, which disappear after 6 months. Both procedures have a serious impact on erectile function, being even greater in the DV group. Differences between groups disappear after 6 months. Copyright® by the International Brazilian Journal of Urology.

    Highlights: ► Cd tolerance and accumulation are constitutive traits in D. viscosa. ► The physiological mechanisms involved in Cd stress differed between clones. ► The metallicolous clone was more Cd tolerant than the non-metallicolous one. ► Antioxidant enzymes had important roles in each clone, especially peroxidases. -- Abstract: Two clones of Dittrichia viscosa (L.) Greuter from contrasting populations, DV-A (metallicolous) and DV-W (non-metallicolous), were studied to compare Cd accumulation and tolerance. After 10 days of hydroponic culture with 0, 5, 10, and 15 mg Cd L{sup −1}, metal accumulation and plant growth were measured as well as other stress markers such as decrease in the content of photosynthetic pigments, lipid peroxidation, phenols, H{sub 2}O{sub 2}, and free proline. We also analyzed the activity of the antioxidant enzymes guaiacol and ascorbate peroxidases, catalase, superoxide dismutase, and glutathione reductase as well as their isoform patterns. Our results confirmed a high Cd tolerance and accumulation in both clones of D. viscosa, which suggests that these traits are constitutive in this species. However, when the Cd concentration in solution exceeded 10 mg Cd L{sup −1}, DV-A was more tolerant than DV-W. The physiological mechanisms involved in Cd tolerance also differed between them, although phenols and guaiacol peroxidase played an important role in both clones. The effective Cd detoxification of DV-A consisted mainly in a promoted ascorbate peroxidase activity and better efficiency of catalase and glutathione reductase enzymes.

  17. Response of water vapour D-excess to land-atmosphere interactions in a semi-arid environment

    Parkes, Stephen D.

    2016-06-30

    The stable isotopic composition of water vapour provides information about moisture sources and processes difficult to obtain with traditional measurement techniques. Recently, it has been proposed that the D-excess of water vapour can provide a diagnostic tracer of continental moisture recycling. However, D-excess exhibits a diurnal cycle that has been observed across a variety of ecosystems and may be influenced by a range of processes beyond regional-scale moisture recycling, including local evaporation (ET) fluxes. There is a lack of measurements of D-excess in evaporation (ET) fluxes, which has made it difficult to assess how ET fluxes modify the Dexcess in water vapour (dv). With this in mind, we employed a chamber-based approach to directly measure D-excess in ET (dET) fluxes. We show that ET fluxes imposed a negative forcing on the ambient vapour and could not explain the higher daytime dv values. The low dET observed here was sourced from a soil water pool that had undergone an extended drying period, leading to low D-excess in the soil moisture pool. A strong correlation between daytime dv and locally measured relative humidity was consistent with an oceanic moisture source, suggesting that remote hydrological processes were the major contributor to daytime dv variability. During the early evening, ET fluxes into a shallow nocturnal inversion layer caused a lowering of dv values near the surface. In addition, transient mixing of vapour with a higher D-excess from above the nocturnal inversion modified these values, causing large variability during the night. These results indicate dET can generally be expected to show

    This in vitro study evaluated the use of laser fluorescence (LF) for the detection of early interproximal carious lesions and whether the detection could be enhanced using a fluorescent dye (DELF). Direct visual examination (DV) was used for comparison. Eighty extracted teeth were used, arranged in 20 blocks, each block having 2 premolars and 2 molars, lined up in a simulated sextant situation. After cleaning with a microabrasion kit, a subcontact window on half of the surfaces (60) was exposed to Carbopol white-spot solution for 5 days. The teeth were remounted in stone and examined by three independent examiners. For LF and DELF an argon laser was used (mixed wavelength of 488 and 514 nm) viewed through glasses (excluding wavelength DELF a sodium fluorescein dye (0. 075%) was applied before examination. A clinical examination light was used for DV. The approximal surfaces were scored for lesion presence or absence. To verify lesion presence, the subcontact area was cut perpendicularly to the surface, stained with rhodamine B, and images were taken using a confocal microscope. The images were analyzed using a histogram program for lesion depth and image area. Lesions were present in 62 out of 120 approximal surfaces, with an average depth of 60 microm (range 17-190 microm). Sensitivity ranges for LF, DELF and DV were 56-74, 61-79 and 58-74%, and specificity ranges 67-78, 86-98 and 83-97%, respectively. With this model DELF compared favorably with DV and LF in sensitivity, but specificity was better for DELF and DV than for LF.

  19. Efficient assembly and secretion of recombinant subviral particles of the four dengue serotypes using native prM and E proteins.

    Full Text Available BACKGROUND: Flavivirus infected cells produce infectious virions and subviral particles, both of which are formed by the assembly of prM and E envelope proteins and are believed to undergo the same maturation process. Dengue recombinant subviral particles have been produced in cell cultures with either modified or chimeric proteins but not using the native forms of prM and E. METHODOLOGY/PRINCIPAL FINDINGS: We have used a codon optimization strategy to obtain an efficient expression of native viral proteins and production of recombinant subviral particles (RSPs for all four dengue virus (DV serotypes. A stable HeLa cell line expressing DV1 prME was established (HeLa-prME and RSPs were analyzed by immunofluorescence and transmission electron microscopy. We found that E protein is mainly present in the endoplasmic reticulum (ER where assembly of RSPs could be observed. Biochemical characterization of DV1 RSPs secretion revealed both prM protein cleavage and homodimerization of E proteins before their release into the supernatant, indicating that RSPs undergo a similar maturation process as dengue virus. Pulse chase experiment showed that 8 hours are required for the secretion of DV1 RSPs. We have used HeLa-prME to develop a semi-quantitative assay and screened a human siRNA library targeting genes involved in membrane trafficking. Knockdown of 23 genes resulted in a significant reduction in DV RSP secretion, whereas for 22 others we observed an increase of RSP levels in cell supernatant. CONCLUSIONS/SIGNIFICANCE: Our data describe the efficient production of RSPs containing native prM and E envelope proteins for all dengue serotypes. Dengue RSPs and corresponding producing cell lines are safe and novel tools that can be used in the study of viral egress as well as in the development of vaccine and drugs against dengue virus.

    Objectives Domestic violence (DV) is hazardous to survivors' health, from injuries sustained and from resultant chronic physical and mental health problems. Support from friends and relatives is significant in the lives of DV survivors; research shows associations between positive support and the health, well-being and safety of survivors. Little is known about how people close to survivors are impacted. The aim of this study was exploratory, with the following research question: what are the health and well-being impacts on adults who provide informal support to female DV survivors? Design A qualitative study using semistructured interviews conducted face to face, by telephone or using Skype. A thematic analysis of the narratives was carried out. Setting Community-based, across the UK. Participants People were eligible to take part if they had had a close relationship (either as friend, colleague or family member) with a woman who had experienced DV, and were aged 16 or over during the time they knew the survivor. Participants were recruited via posters in community venues, social media and radio advertisement. 23 participants were recruited and interviewed; the majority were women, most were white and ages ranged from mid-20s to 80. Results Generated themes included: negative impacts on psychological and emotional well-being of informal supporters, and related physical health impacts. Some psychological impacts were over a limited period; others were chronic and had the potential to be severe and enduring. The impacts described suggested that those providing informal support to survivors may be experiencing secondary traumatic stress as they journey alongside the survivor. Conclusions Friends and relatives of DV survivors experience substantial impact on their own health and well-being. There are no direct services to support this group. These findings have practical and policy implications, so that the needs of informal supporters are legitimised and met. PMID
