    ENG, or endoglin, is a cell surface adhesion protein involved the regulation of angiogenesis. ENG is a major glycoprotein of the vascular endothelium and is also a component of the transforming growth factor beta receptor complex. ENG binds to the beta1 and beta3 peptides with high affinity. ENG may also be involved in preeclampsia and several types of cancer. There are several isoforms encoded by transcript variants.

    Advanced beam-driven FRCs (Field Reversed Configurations) represent a plasma configuration which is aimed to reach steady state through external sustainment. In an advanced beam-driven FRC the plasma has a very rich selection of orbit types, namely, drift, betatron, figure-8 and type-I. How much each type contributes to the total quantity of orbits strongly depends on both plasma and external field parameters and it may include regular and stochastic orbits with very different ratios. We study the orbit type distribution as well as the fractions of regular and stochastic orbits for a set of realistic advanced beam-driven FRC equilibria in very different plasma regimes. In particular, we investigate the dependences of the orbit type distribution on the equilibrium parameters and we discuss the relevant role of the FRC parameter s in providing a good estimate of the total quantity of stochastic orbits. A first investigation of the possible role of stochastic orbits in thermalizing processes induced by magnetic pumping techniques is presented.

    Collaborative research project with Tri Alpha Energy has been started and we have developed a new compact toroid (CT) injector for the C-2 device, mainly for fueling field-reversed configurations (FRCs). The CT is formed by a magnetized coaxial plasma-gun (MCPG), which consists of coaxial cylinder electrodes; a spheromak-like plasma is generated by discharge and pushed out from the gun by Lorentz force. The inner diameter of outer electrode is 83.1 mm and the outer diameter of inner electrode is 54.0 mm. The surface of the inner electrode is coated with tungsten in order to reduce impurities coming out from the electrode. The bias coil is mounted inside of the inner electrode. We have recently conducted test experiments and achieved a supersonic CT translation speed of up to ~100 km/s. Other typical plasma parameters are as follows: electron density ~ 5 × 1021 m-3, electron temperature ~ 40 eV, and the number of particles ~0.5-1.0 × 1019. The CT injector is now planned to be installed on C-2 and the first CT injection experiment will be conducted in the near future. The detailed MCPG design as well as the test experimental results will be presented.

  6. HIFLUX: OBLATE FRCS, DOUBLE HELICES,SPHEROMAKS AND RFPS IN ONE SYSTEM

    2003-07-01

    OAK-B135 High magnetic flux is required for thermonuclear FRC reactors and, more immediately, to advance the FRC experimental program in general. Oblate FRCs are of special interest because they are predicted to have certain improved MHD stability over elongated FRCs, and oblate FRCs may yield the most compact, magnetically confined fusion reactors. Neither oblate nor high-flux FRCs have been investigated experimentally to date. Our presently proposed technique is to make two high-flux, oppositely-handed plasmas by a pair of large, external, reversed-field pinch (RFP) sources. The plasmas would propagate as two Taylor-relaxed double-helix plasmas, to an oblate main plasma chamber, where they would relax further to a counter-helicity pair of spheromaks, which would finally merge into a single high-flux FRC. A concept for a new experimental facility, HIFLUX, to make and study high-magnetic-flux oblate Field-Reversed Configuration (FRC) plasmas, is described. Similar principles might also enable high flux non-inductive startup of other plasma devices.

    The gene engE, coding for endoglucanase E, one of the three major subunits of the Clostridium cellulovorans cellulosome, has been isolated and sequenced. engE is comprised of an open reading frame (ORF) of 3,090 bp and encodes a protein of 1,030 amino acids with a molecular weight of 111,796. The amino acid sequence derived from engE revealed a structure consisting of catalytic and noncatalytic domains. The N-terminal-half region of EngE consisted of a signal peptide of 31 amino acid residues and three repeated surface layer homology (SLH) domains, which were highly conserved and homologous to an S-layer protein from the gram-negative bacterium Caulobacter crescentus. The C-terminal-half region, which is necessary for the enzymatic function of EngE and for binding of EngE to the scaffolding protein CbpA, consisted of a catalytic domain homologous to that of family 5 of the glycosyl hydrolases, a domain of unknown function, and a duplicated sequence (DS or dockerin) at its C terminus. engE is located downstream of an ORF, ORF1, that is homologous to the Bacillus subtilis phosphomethylpyrimidine kinase (pmk) gene. The unique presence of three SLH domains and a DS suggests that EngE is capable of binding both to CbpA to form a CbpA-EngE cellulosome complex and to the surface layer of C. cellulovorans.

    Oblate field-reversed configurations FRCs have been sustained for >300 µs, or >15 magnetic diffusion times, through the use of an inductive solenoid. These argon FRCs can have their poloidal flux sustained or increased, depending on the timing and strength of the induction. An inward pinch is observed during sustainment, leading to a peaking of the pressure profile and maintenance of the FRC equilibrium. The good stability observed in argon (and krypton) does not transfer to lighter gases, which develop terminal co-interchange instabilities. The stability in argon and krypton is attributed to a combination of external field shaping, magnetic diffusion, and finite-Larmor radius effects.

    The goal of the C-2U experiment is to use neutral beam heating and edge biasing to sustain an advanced beam-driven FRC for many milliseconds, longer than the growth times of known instabilities and the resistive wall time. To guide the experiment further into unexplored parameter regimes, it is desirable to have a stability code suitable for beam-driven FRC plasmas, in which the bulk of ion orbits are not Larmor-like and hence gyrokinetic approximations are inapplicable. Fully kinetic ions are required for stability simulations of beam driven FRCs, as are multiple ion species, end boundary conditions, and a resistive boundary. To meet these challenges a new 3D quasineutral hybrid code, FPIC, is being developed. FPIC has a choice of zero electron mass and finite electron mass Ohm's law solvers. Uniform staggered grids, finite differencing, and cut cell boundaries are used to simplify and optimize the PIC while allowing arbitrary boundary shapes. Finite resistivity of the boundary is implemented by coupling free-space exterior solutions to the cut-cell edges. The code is MPI parallelized and the particle push is GPU accelerated. Code benchmarks will be presented including the stability of the FRC tilt mode.

    Chang and Eng, the two young men who would eventually be known around the world as the 'original' Siamese twins, arrived in the West in 1829. They were brought to the West to be examined by medical men and to be exhibited to the general public. Throughout the 19th century in Britain and the US, 'monstrosities' such as Chang and Eng, as well as a host of other people with unusual anatomies, were considered both spectacles worthy of public display and edifying medical subjects with the potential to build on medical knowledge. The unique case of Chang and Eng illustrates that the boundary between what is of legitimate medical interest and what is considered merely spectacle is often blurred. PMID:14652037

    To evaluate the marginal adaptation of endodontically treated molars restored with CAD/CAM composite resin endocrowns either with or without reinforcement by fibre reinforced composites (FRCs), used in different configurations. 32 human endodontically treated molars were cut 2 mm over the CEJ. Two interproximal boxes were created with the margins located 1 mm below the CEJ (distal box) and 1 mm over the CEJ (mesial box). All specimens were divided in four groups (n = 8). The pulp chamber was filled with: group 1 (control), hybrid resin composite (G-aenial Posterior, GC); group 2, as group 1 but covered by 3 meshes of E-glass fibres (EverStick NET, Stick Tech); group 3, FRC resin (EverX Posterior, GC); group 4, as group 3 but covered by 3 meshes of E-glass fibres. The crowns of all teeth were restored with CAD/CAM composite resin endocrowns (LAVA Ultimate, 3M). All specimens were thermo-mechanically loaded in a computer-controlled chewing machine (600,000 cycles, 1.6 Hz, 49 N and simultaneously 1500 thermo-cycles, 60 s, 5-55 °C). Marginal analysis before and after the loading was carried out on epoxy replicas by SEM at 200× magnification. For all the groups, the percentage values of perfect marginal adaptation after loading were always significantly lower than before loading (p < 0.05). The marginal adaptation before and after loading was not significantly different between the experimental groups (p > 0.05). Within the limitations of this in vitro study, the use of FRCs to reinforce the pulp chamber of devitalized molars restored with CAD/CAM composite resin restorations did not significantly influenced their marginal quality.

    Cuff electrodes have several advantages for in situ recording ENG signal. They are easy to implant and not very invasive for the patient. Nevertheless, they are subject to background parasitic noise, especially the EMG generated by the muscles. We show that the use of cuff electrodes with large numbers of poles can increase their sensitivity and their selectivity with respect to an efficient noise rejection. We investigate several configurations and compare the performances of a tripolar cuff electrode versus a multipolar one in numerical simulation.

  13. On cuff imbalance and tripolar ENG amplifier configurations.

    Electroneurogram (ENG) recording techniques benefit from the use of tripolar cuffs because they assist in reducing interference from sources outside the cuff. However, in practice the performance of ENG amplifier configurations, such as the quasi-tripole and the true-tripole, has been widely reported to be degraded due to the departure of the tripolar cuff from ideal behavior. This paper establishes the presence of cuff imbalance and investigates its relationship to cuff asymmetry, cuff end-effects and interference source proximity. The paper also presents a comparison of the aforementioned amplifier configurations with a new alternative, termed the adaptive-tripole, developed to automatically compensate for cuff imbalance. The output signal-to-interference ratio of the three amplifier configurations were compared in vivo for two interference signals (stimulus artifact and M-wave) superimposed on compound action potentials. The experiments showed (for the first time) that the two interference signals result in different cuff imbalance values. Nevertheless, even with two distinct cuff imbalances present, the adaptive-tripole performed better than the other two systems in 61.9% of the trials. PMID:15709669

  15. Functional characterization of EngA(MS), a P-loop GTPase of Mycobacterium smegmatis.

    Bacterial P-loop GTPases belong to a family of proteins that selectively hydrolyze a small molecule guanosine tri-phosphate (GTP) to guanosine di-phosphate (GDP) and inorganic phosphate, and regulate several essential cellular activities such as cell division, chromosomal segregation and ribosomal assembly. A comparative genome sequence analysis of different mycobacterial species indicates the presence of multiple P-loop GTPases that exhibit highly conserved motifs. However, an exact function of most of these GTPases in mycobacteria remains elusive. In the present study we characterized the function of a P-loop GTPase in mycobacteria by employing an EngA homologue from Mycobacterium smegmatis, encoded by an open reading frame, designated as MSMEG_3738. Amino acid sequence alignment and phylogenetic analysis suggest that MSMEG_3738 (termed as EngA(MS)) is highly conserved in mycobacteria. Homology modeling of EngA(MS) reveals a cloverleaf structure comprising of α/β fold typical to EngA family of GTPases. Recombinant EngA(MS) purified from E. coli exhibits a GTP hydrolysis activity which is inhibited by the presence of GDP. Interestingly, the EngA(MS) protein is co-eluted with 16S and 23S ribosomal RNA during purification and exhibits association with 30S, 50S and 70S ribosomal subunits. Further studies demonstrate that GTP is essential for interaction of EngA(MS) with 50S subunit of ribosome and specifically C-terminal domains of EngA(MS) are required to facilitate this interaction. Moreover, EngA(MS) devoid of N-terminal region interacts well with 50S even in the absence of GTP, indicating a regulatory role of the N-terminal domain in EngA(MS)-50S interaction. PMID:22506030

  16. The Eng1 β-Glucanase Enhances Histoplasma Virulence by Reducing β-Glucan Exposure

    ABSTRACT The fungal pathogen Histoplasma capsulatum parasitizes host phagocytes. To avoid antimicrobial immune responses, Histoplasma yeasts must minimize their detection by host receptors while simultaneously interacting with the phagocyte. Pathogenic Histoplasma yeast cells, but not avirulent mycelial cells, secrete the Eng1 protein, which is a member of the glycosylhydrolase 81 (GH81) family. We show that Histoplasma Eng1 is a glucanase that hydrolyzes β-(1,3)-glycosyl linkages but is not required for Histoplasma growth in vitro or for cell separation. However, Histoplasma yeasts lacking Eng1 function have attenuated virulence in vivo, particularly during the cell-mediated immunity stage. Histoplasma yeasts deficient for Eng1 show increased exposure of cell wall β-glucans, which results in enhanced binding to the Dectin-1 β-glucan receptor. Consistent with this, Eng1-deficient yeasts trigger increased tumor necrosis factor alpha (TNF-α) and interleukin-6 (IL-6) cytokine production from macrophages and dendritic cells. While not responsible for large-scale cell wall structure and function, the secreted Eng1 reduces levels of exposed β-glucans at the yeast cell wall, thereby diminishing potential recognition by Dectin-1 and proinflammatory cytokine production by phagocytes. In α-glucan-producing Histoplasma strains, Eng1 acts in concert with α-glucan to minimize β-glucan exposure: α-glucan provides a masking function by covering the β-glucan-rich cell wall, while Eng1 removes any remaining exposed β-glucans. Thus, Histoplasma Eng1 has evolved a specialized pathogenesis function to remove exposed β-glucans, thereby enhancing the ability of yeasts to escape detection by host phagocytes. PMID:27094334

    Emergency department (ED) wait times have continued to worsen despite receiving considerable attention for more than 2 decades and despite the availability of a variety of methods to restructure care in a more streamlined fashion. This article offers an economic framework that abstracts away from the details of operations research to understand the fundamental disincentives to improving wait times. Hospitals that reduce wait times are financially penalized if they must provide more uncompensated care as a result. Pending changes under the Patient Protection and Affordable Care Act are considered. We find that the likely effect of the Patient Protection and Affordable Care Act's insurance expansion is to reduce this penalty for improving ED wait times. Consequently, mandating adoption of solutions to ED crowding may be unnecessary and counterproductive. If the insurance expansion is insufficient to fully solve the problem, the hospital value-based purchasing initiative should adopt wait times as a goal in its next iteration. PMID:24332901

    The biennial international conference on Extended Defects in Semiconductors started in 1978 with a meeting in Hünfeld, Germany. Subsequent meetings rotated between Poland, France, Great Britain, Germany, Russia and Italy, culminating in EDS2004 in Chernogolovka, EDS2006 in Halle and EDS2008 in Poitiers. EDS2010 was held at the University of Sussex at Brighton, UK from September 19th to 24th. An extension of the tabulation of this history, which first appeared on the EDS2006 website, is given in the attached PDF. It is with sadness that we note one of the founders of the series, Prof. Dr Helmut Alexander, passed away on 3 December 2009 and we were proud to dedicate EDS2010 to his memory. It has become a tradition to make an award in his name, and this year it was made to Ivan Isacov for his poster "Electrical levels of dislocation networks in p- and n-type silicon". A short and warm celebration of Prof. Dr Alexander's life by his friends and colleagues, Prof. Drs Helmut Gottschalk, Eicke Weber and Wolfgang Schröter, is included in this volume. The conference was a forum for the state-of-the-art of investigation and modelling of extended defects in semiconductors. Scientists from universities, research institutes and industry made contributions to a deeper understanding of extended defects, their interaction with point defects and their role in the development of semiconductor technology. The remit of the conference included extended defects, nanostructures, nanoparticles, quantum dots and interfaces within semiconducting materials ranging from narrow to wide band gaps, including graphene-derived materials and diamond. Scientific interests range from defect geometry, electronic structure, dynamics, spectroscopy, microscopy, reactions and chemistry to introduction mechanisms, such as implantation and strained layers and the operation of devices such as integrated circuits, heterostructures, and solar cells. The organisers were confronted with a long period between

    Eng2 is a glucanase required for spore release, although it is also expressed during vegetative growth, suggesting that it might play other cellular functions. Its homology to the Saccharomyces cerevisiae Acf2 protein, previously shown to promote actin polymerization at endocytic sites in vitro, prompted us to investigate its role in endocytosis. Interestingly, depletion of Eng2 caused profound defects in endocytic uptake, which were not due to the absence of its glucanase activity. Analysis of the dynamics of endocytic proteins by fluorescence microscopy in the eng2Δ strain unveiled a previously undescribed phenotype, in which assembly of the Arp2/3 complex appeared uncoupled from the internalization of the endocytic coat and resulted in a fission defect. Strikingly also, we found that Eng2-GFP dynamics did not match the pattern of other endocytic proteins. Eng2-GFP localized to bright cytosolic spots that moved around the cellular poles and occasionally contacted assembling endocytic patches just before recruitment of Wsp1, the Schizosaccharomyces pombe WASP. Interestingly, Csh3-YFP, a WASP-interacting protein, interacted with Eng2 by co-immunoprecipitation and was recruited to Eng2 in bright cytosolic spots. Altogether, our work defines a novel endocytic functional module, which probably couples the endocytic coat to the actin module. PMID:25040903

    The Letšeng-la-Terae kimberlites are situated 3100 m above sea level in the Maloti Mountains of Lesotho, southern Africa. The principal economic bodies are two Late Cretaceous, low grade, 1-3.5 carats/hundred ton (cpht), kimberlite pipes that host high-value diamonds realising US 2000-2500/carat (/ct) in 2008 terms. Locally, the larger kimberlite body is referred to as the Main Pipe (17.2 ha) and the smaller one is called the Satellite Pipe (5.2 ha). These pipes, and their associated eluvial and proximal alluvial deposits, are renowned for yielding large, "D" colour, gem quality diamonds, including + 100 carat (ct) stones. Earlier artisanal effort (1959-1977) and formal mining (1977-1982) produced 335,000 carats (cts), including the 601 ct Lesotho Brown in 1968. In 2003, Letšeng Diamonds Limited re-commenced mining operations and had produced 265,000 cts by the end of July 2008, including 24 + 100 ct diamonds, the largest of which was the 603 ct Lesotho Promise. We report here on the unusual characteristics of the Letšeng diamond population that include: 75% gem quality that is more commonly associated with alluvial diamond deposits, large average stone size of ca. 1 carat/stone (ct/stn) that is also more typical of certain alluvial diamond placers, high-yielding, rounded to flattened irregular, resorbed dodecahedral shapes (Main Pipe 67% and Satellite Pipe 87%) with subordinate dodecahedral macle (Main Pipe 32% and Satellite Pipe 12%) and broken (ca. 1%) forms. In both pipes the octahedral component is virtually absent (< 0.1%), economically favourable colour mix (ca. 33% white colour diamonds in both pipes), abundance of nitrogen-free, "D" colour, Type IIa diamonds that dominate the internationally recognised "special" stone size fraction which covers all diamonds larger than + 10.8 cts (Main Pipe 32% and Satellite Pipe 51%). During 2008, these larger, "special" diamonds commanded prices in excess of US 15,000/ct, contributing ca. 75% of the revenue generated

    Research Pilot Edward T. Schneider is shown sitting in the cockpit of a McDonnell Douglas F/A-18 Hornet that was used in the High Angle-of-Attack Research Vehicle (HARV) program at the National Aeronautics and Space Administration's Ames - Dryden Flight Research Facility. When the aircraft arrived at the Dryden Facility in 1987, from the US Naval Air Test Center, Patuxent River, Maryland, it consisted of parts in crates. The aircraft crew made an airplane from those parts, and in doing so they took a 'sow's ear' and created a 'silk purse', thus the name on the side of the aircraft. Ed's helmet is from his time in the Navy. The design was taken from the Flag that is flown on the bow of a Navy ship, referred to as the Jack, and is navy blue with the 50 States being represented by the white stars. Ed arrived at the NASA Ames-Dryden Flight Research Facility (later renamed the Dryden Flight Research Center) on July 5, 1982, as a Navy Liaison Officer, becoming a NASA research pilot one year later.

    Many ribosome-interacting GTPases, with proposed functions in ribosome biogenesis, are also implicated in the cellular regulatory coupling between ribosome assembly process and various growth control pathways. EngA is an essential GTPase in bacteria, and intriguingly, it contains two consecutive GTPase domains (GD), being one-of-a-kind among all known GTPases. EngA is required for the 50S subunit maturation. However, its molecular role remains elusive. Here, we present the structure of EngA bound to the 50S subunit. Our data show that EngA binds to the peptidyl transferase center (PTC) and induces dramatic conformational changes on the 50S subunit, which virtually returns the 50S subunit to a state similar to that of the late-stage 50S assembly intermediates. Very interestingly, our data show that the two GDs exhibit a pseudo-two-fold symmetry in the 50S-bound conformation. Our results indicate that EngA recognizes certain forms of the 50S assembly intermediates, and likely facilitates the conformational maturation of the PTC of the 23S rRNA in a direct manner. Furthermore, in a broad context, our data also suggest that EngA might be a sensor of the cellular GTP/GDP ratio, endowed with multiple conformational states, in response to fluctuations in cellular nucleotide pool, to facilitate and regulate ribosome assembly.

    This study describes the molecular and biochemical characterization of the β-1,4-endoglucanase gene (Mj-eng-3) from the root knot nematode Meloidogyne javanica. A 2156-bp genomic DNA sequence of Mj-eng-3 containing six introns was obtained. Mj-eng-3 was localized in the subventral esophageal glands of M. javanica juveniles by in situ hybridization. Real-time RT-PCR assay showed that the highest transcriptional level of Mj-eng-3 occurred in pre-parasitic second-stage juveniles, and this high expression persisted in parasitic second-stage juveniles. Recombinant MJ-ENG-3 degraded carboxymethylcellulose and optimum enzyme activity at 40°C and pH 8.0. EDTA, Mg(2+), Mn(2+), Ca(2+), Co(2+), and Cu(2+) did not affect the activity of MJ-ENG-3; however, Zn(2+) and Fe(2+) inhibited MJ-ENG-3 enzyme activity. In planta Mj-eng-3 RNAi assay displayed a reduction in the number of nematodes and galls in transgenic tobacco roots. These results suggested that MJ-ENG-3 could be secreted by M. javanica to degrade the cellulose of plant cell walls to facilitate its entry and migration during the early stages of parasitism.

    This paper presents an AC-coupled instrumentation amplifier for electroneurogram (ENG) activity recording. For this design, we evaluate gain and noise requirements based on interference sources (electrodes, power line, EMG). The circuit has been implemented in a commercially-available 0.35μm CMOS technology with total power consumption 460μW. The amplifier achieves CMRR 107 dB and integrated input referred noise 940 nV. The gain is 63 dB and the bandwidth is 0.5 Hz- 13 kHz. The chosen topology enables to minimise on-chip capacitance (only 27 pF), with a total chip area of 0.4mm2. PMID:26736847

  16. Potassium Acts as a GTPase-Activating Element on Each Nucleotide-Binding Domain of the Essential Bacillus subtilis EngA

    2012-01-01

    EngA proteins form a unique family of bacterial GTPases with two GTP-binding domains in tandem, namely GD1 and GD2, followed by a KH (K-homology) domain. They have been shown to interact with the bacterial ribosome and to be involved in its biogenesis. Most prokaryotic EngA possess a high GTPase activity in contrast to eukaryotic GTPases that act mainly as molecular switches. Here, we have purified and characterized the GTPase activity of the Bacillus subtilis EngA and two shortened EngA variants that only contain GD1 or GD2-KH. Interestingly, the GTPase activity of GD1 alone is similar to that of the whole EngA, whereas GD2-KH has a 150-fold lower GTPase activity. At physiological concentration, potassium strongly stimulates the GTPase activity of each protein construct. Interestingly, it affects neither the affinities for nucleotides nor the monomeric status of EngA or the GD1 domain. Thus, potassium likely acts as a chemical GTPase-activating element as proposed for another bacterial GTPase like MnmE. However, unlike MnmE, potassium does not promote dimerization of EngA. In addition, we solved two crystal structures of full-length EngA. One of them contained for the first time a GTP-like analogue bound to GD2 while GD1 was free. Surprisingly, its overall fold was similar to a previously solved structure with GDP bound to both sites. Our data indicate that a significant structural change must occur upon K+ binding to GD2, and a comparison with T. maritima EngA and MnmE structures allowed us to propose a model explaining the chemical basis for the different GTPase activities of GD1 and GD2.

    The term explosive detection system (EDS) is used by the TSA to describe equipment that is certified to detect explosives in checked bags. The EDS, as certified, by the TSL must consist of device for interrogating a bag and an automated detection algorithm (ATD) for evaluating the results of the interrogation. We only consider CT as the interrogation device in this report. A schematic drawing of a CT-based EDS is shown in Figure 2. The output of the ATD is the binary decision of alarm or non-alarm. Alarms may true- or false-positives. Non-alarms may be true- or false-negatives. False positives are also denoted false alarms. The true detection means that the ATD reports an alarm when a threat is present in the scanned bag. The probability of detecting a threat given that a threat is present is denoted the probability of detection (PD). The probability of false alarm (PFA) is the case when an alarm is reported when a threat is not present in a bag. Certification in this context means passing tests for PD and PFA at the TSL. The results of the EDS include CT cross-sectional images of the bag and specifics about the alarmed objects generated by ATD. These results are presented on a display so that a person may override the decision of ATD and declare the alarm to be a non-alarm. This process is denoted clearing. Bags that are not cleared by the person are sent to a secondary inspection process. Here the bags may be opened or assessed with explosive trace detection (ETD) in order to clear the bags. Bags that are not cleared at this point are evaluated by an ordinance disposal team. The CT scanner along with ATD is denoted Level 1 screening. The process of clearing on a display is denoted Level 2 screening. Secondary inspection is denoted Level 3 screening. Vendors of the deployed EDSs supply the TSA with equipment for all three levels. Therefore, the term EDS may include the equipment provided for Levels 1, 2 and 3. A schematic diagram of an EDS and the levels of

    The recently identified phylogenetic subgroup B5 of fungal glycoside hydrolase family 18 genes encodes enzymes with mannosyl glycoprotein endo-N-acetyl-β-D-glucosaminidase (ENGase)-type activity. Intracellular ENGase activity is associated with the endoplasmic reticulum associated protein degradation pathway (ERAD) of misfolded glycoproteins, although the biological relevance in filamentous fungi is not known. Trichoderma atroviride is a mycoparasitic fungus that is used for biological control of plant pathogenic fungi. The present work is a functional study of the T. atroviride B5-group gene Eng18B, with emphasis on its role in fungal growth and antagonism. A homology model of T. atroviride Eng18B structure predicts a typical glycoside hydrolase family 18 (αβ)8 barrel architecture. Gene expression analysis shows that Eng18B is induced in dual cultures with the fungal plant pathogens Botrytis cinerea and Rhizoctonia solani, although a basal expression is observed in all growth conditions tested. Eng18B disruption strains had significantly reduced growth rates but higher conidiation rates compared to the wild-type strain. However, growth rates on abiotic stress media were significantly higher in Eng18B disruption strains compared to the wild-type strain. No difference in spore germination, germ-tube morphology or in hyphal branching was detected. Disruption strains produced less biomass in liquid cultures than the wild-type strain when grown with chitin as the sole carbon source. In addition, we determined that Eng18B is required for the antagonistic ability of T. atroviride against the grey mould fungus B. cinerea in dual cultures and that this reduction in antagonistic ability is partly connected to a secreted factor. The phenotypes were recovered by re-introduction of an intact Eng18B gene fragment in mutant strains.

    A five-gene cluster around the gene in Clostridium cellulovorans that encodes endoglucanase EngL, which is involved in plant cell wall degradation, has been cloned and sequenced. As a result, a mannanase gene, manA, has been found downstream of engL. The manA gene consists of an open reading frame with 1,275 nucleotides encoding a protein with 425 amino acids and a molecular weight of 47,156. ManA has a signal peptide followed by a duplicated sequence (DS, or dockerin) at its N terminus and a catalytic domain which belongs to family 5 of the glycosyl hydrolases and shows high sequence similarity with fungal mannanases, such as Agaricus bisporus Cel4 (17.3% identity), Aspergillus aculeatus Man1 (23.7% identity), and Trichoderma reesei Man1 (22.7% identity). Sodium dodecyl sulfate-polyacrylamide gel electrophoresis and N-terminal amino acid sequence analyses of the purified recombinant ManA (rManA) indicated that the N-terminal region of the rManA contained a DS and was truncated in Escherichia coli cells. Furthermore, Western blot analysis indicated that ManA is one of the cellulosomal subunits. ManA production is repressed by cellobiose. PMID:10613891

    Understanding the appearance of vestibular symptoms during periods of convalescence after surgery for the treatment of Meniere's disease is important for determining when a patient can return to work as well as the long-term results of the operation. We have treated 20 cases of intractable Meniere's disease with endolymphatic sac drainage & steroid-instillation surgery (EDSS) [Kitahara T, et al., Ann Otol Rhlnol Laryngol in press, 2000] and observed the subjective symptoms and objective vestibular findings using electronystagmogram (ENG) during the subsequent period of convalescence. The average postoperative durations of subjective static and evoked vestibular symptoms were 1.7 and 6.7 days, respectively. Those of spontaneous, positional and positioning nystagmus observed using ENG were 1.2, 2.0 and 7.9 days, respectively. In cases with a long history of Meniere's disease, postoperative static vestibular sensation and positional nystagmus lasted significantly longer than in cases with short histories. In cases with poorly developed temporal bony pneumatization in the area behind the posterior semicircular canal, postoperative evoked vestibular sensations and positioning nystagmus lasted significantly longer than in cases with well developed temporal bony pneumatization. Vestibular symptoms resulting from direct invasion during EDSS were considered to be slighter than those resulting from vestibular neurectomy or gentamicin treatment and almost the same as those resulting from endolymphatic sac surgery.

    Instabilities of an EDS maglev suspension system with 3 D.O.F. and 5 D.O.F. vehicles traveling on a double L-shaped set of guideway conductors have been investigated with various experimentally measured magnetical force data incorporated into the theoretical models. Divergence and flutter are obtained from both analytical and numerical solutions for coupled vibration of the 3 D.O.F. maglev vehicle model. Instabilities of five direction motions (heave, slip, rill, pitch and yaw) are observed for the 4 D.O.F. vehicle model. It demonstrates that system parameters, such as, system damping, vehicle geometry and coupling effects among five different motions play very important roles in the occurrence of dynamic instabilities of maglev vehicles.

    BACKGROUND: There are few data regarding mechanical ventilation and ARDS in the ED. This could be a vital arena for prevention and treatment. METHODS: This study was a multicenter, observational, prospective, cohort study aimed at analyzing ventilation practices in the ED. The primary outcome was the incidence of ARDS after admission. Multivariable logistic regression was used to determine the predictors of ARDS. RESULTS: We analyzed 219 patients receiving mechanical ventilation to assess ED ventilation practices. Median tidal volume was 7.6 mL/kg predicted body weight (PBW) (interquartile range, 6.9-8.9), with a range of 4.3 to 12.2 mL/kg PBW. Lung-protective ventilation was used in 122 patients (55.7%). The incidence of ARDS after admission from the ED was 14.7%, with a mean onset of 2.3 days. Progression to ARDS was associated with higher illness severity and intubation in the prehospital environment or transferring facility. Of the 15 patients with ARDS in the ED (6.8%), lung-protective ventilation was used in seven (46.7%). Patients who progressed to ARDS experienced greater duration in organ failure and ICU length of stay and higher mortality. CONCLUSIONS: Lung-protective ventilation is infrequent in patients receiving mechanical ventilation in the ED, regardless of ARDS status. Progression to ARDS is common after admission, occurs early, and worsens outcome. Patient- and treatment-related factors present in the ED are associated with ARDS. Given the limited treatment options for ARDS, and the early onset after admission from the ED, measures to prevent onset and to mitigate severity should be instituted in the ED.

    The collection and processing of MicroED data are presented. MicroED, a method at the intersection of X-ray crystallography and electron cryo-microscopy, has rapidly progressed by exploiting advances in both fields and has already been successfully employed to determine the atomic structures of several proteins from sub-micron-sized, three-dimensional crystals. A major limiting factor in X-ray crystallography is the requirement for large and well ordered crystals. By permitting electron diffraction patterns to be collected from much smaller crystals, or even single well ordered domains of large crystals composed of several small mosaic blocks, MicroED has the potential to overcome the limiting size requirement and enable structural studies on difficult-to-crystallize samples. This communication details the steps for sample preparation, data collection and reduction necessary to obtain refined, high-resolution, three-dimensional models by MicroED, and presents some of its unique challenges.

    Objectives Recent health policy changes have focused efforts on reducing emergency department (ED) visits as a way to reduce costs and improve quality of care. This was a systematic review of interventions based outside the ED aimed at reducing ED use. Methods This study was designed as a systematic review. We reviewed the literature on interventions in five categories: patient education, creation of additional non-ED capacity, managed care, prehospital diversion, and patient financial incentives. Studies written in English, with interventions administered outside of the ED, and a comparison group where ED use was an outcome, were included. Two independent reviewers screened search results using MEDLINE, Cochrane, OAIster, or Scopus. The following data were abstracted from included studies: type of intervention, study design, population, details of intervention, effect on ED use, effect on non-ED health care use, and other health and financial outcomes. Quality of individual articles was assessed using Grading of Recommendations Assessment, Development, and Evaluation (GRADE) guidelines. Results Of 39 included studies, 34 were observational and five were randomized controlled trials. Two of five studies on patient education found reductions in ED use ranging from 21% to 80%. Out of 10 studies of additional non-ED capacity, four showed decreases of 9% to 54%, and one a 21% increase. Both studies on prehospital diversion found reductions of 3% to 7%. Of 12 studies on managed care, 10 had decreases ranging from 1% to 46%. Nine out of 10 studies on patient financial incentives found decreases of 3% to 50%, and one a 34% increase. Nineteen studies reported effect on non-ED use with mixed results. Seventeen studies included data on health outcomes, but 13 of these only included data on hospitalizations rather than morbidity and mortality. Seven studies included data on cost outcomes. According to the GRADE guidelines, all studies had at least some risk of bias, with four

    Introduction The objective of this study was to explore associations between presenting chief complaints of prolonged symptomatology, patient usage of the emergency department (ED), and underlying depression so that emergency physicians may better target patients for depression screening. Methods A convenience sample of ED patients were administered the Beck Depression Inventory-II (BDI-II) to assess for depression. We correlated completed BDI-II surveys to patient information including demographics, pertinent history of present illness information, and past medical history. Results Out of 425 participants screened, we identified complaints of two weeks or longer in 92 patients (22%). Of these patients, mild to severe depression was recognized in over half of the population (47), yet only nine patients reported a prior depression diagnosis. These 92 patients also visited the ED three times as frequently as those patients with more acute complaints (p<0.001). Finally, our study showed that patients with mild to severe depression had three times as many ED visits compared to patients with minimal or no depression (p<0.001). Conclusion Patients with complaints of symptomatology two weeks or longer are more likely to have underlying depression when presenting to the ED. Patients with three or more ED visits within the past year also have a greater incidence of underlying depression. We found a strong correlation between complaints with symptomatology of two weeks or longer and multiple ED visits, in which underlying depression may have contributed to these patients’ ED visits.

    Chest pain is the most common complaint among cocaine users who present to the ED seeking care and many hospital resources are applied to stratify cocaine users in regard to future cardiac morbidity and mortality. Little is known about the longitudinal cardiac and non cardiac medical outcomes of cocaine users who have been stratified to an ED observation period following their ED visit. Objectives to examine one-year cardiac outcomes in a low-intermediate risk sample of patients with cocaine- associated chest pain in an urban ED, as well as to examine ED recidivism one year for cardiac and non-cardiac complaints. Methods Prospective consecutive cohort study of patients (18–60 years) who presented to an urban Level 1 ED with cocaine-associated chest pain and were risk stratified to low-intermediate cardiac risk. Exclusion criteria: EKG suggestive of AMI, elevated serum cardiac markers, history of AMI or CABG, hemodynamic instability, unstable angina. Baseline interviews using validated measures of health functioning, and substance use were conducted during CPOU stay, and 3, 6, and 12 months. ED utilization during the study year was abstracted from medical chart. Zero-Inflated Poisson regression analyses were conducted to predict recurrent ED visits. Results 219 participants (73% participation) were enrolled, 65% returned to the ED post index visit; 23% returned for chest pain, of these 66% had a positive cocaine urine screen. No patient had an AMI within the one year follow up period. Patients with continued cocaine use were more likely to have a recurrent ED visit (p<0.001) but these repeat visits were most often related to musculoskeletal pain (21%), and injury (30%) rather than potential cardiac complaints. Conclusions Patients with cocaine-associated chest pain who are low to intermediate cardiac risk and complete a CPOU protocol have less then 1% rate of MI in the subsequent 12-months. PMID:18824277

    An increase in the number of patients visiting emergency departments (EDs) presents an opportunity for additional revenue if hospitals take four steps to optimize resources: Streamline the patient pathway and reduce the amount of time each patient occupies a bed in the ED. Schedule staff according to the busy and light times for patient arrivals. Perform registration and triage bedside, reducing initial wait times. Create an area for patients to wait for test results so beds can be freed up for new arrivals. PMID:27451568

    Established in the early 1970s, EdGEO supports locally driven geosciences workshops for Canadian teachers. Workshops are organized by geoscientists and teachers, and typically have field, laboratory and classroom components. Grants of up to $3000 per workshop are available from the National EdGEO Program. By providing educational opportunities for today's teachers and, through them, their students, EdGEO seeks to cultivate a heightened awareness of our planet. EdGEO workshops provide teachers with potential fieldtrip sites for their students and the knowledge, enthusiasm and materials to inspire their students to engage in geoscience. Networking opportunities with local experts promote the importance of the geoscience profession. The expected result is an improved capacity on the part of Canadians to understand the Earth and to make informed decisions, especially with regard to the use of mineral and energy resources, the maintenance and remediation of the environment, and response to geological hazards. There exists a critical need to provide teachers with training and resources to tackle their Earth science curricula. In 2008, EdGEO supported fourteen workshops, with an unprecedented 521 teachers attending. These teachers then used our resources to reach an estimated 14,000 students during that single academic year. EdGEO workshops are locally driven and are therefore very diverse. Workshops are strongly tied to the provincial curriculum, focus on a specific geoscience topic, or may be largely field-based to demonstrate and practice how field activities could be incorporated into Earth science teaching. Many strive to include all of these important components. Geoscientists and teachers work collaboratively to develop and deliver EdGEO workshops to ensure that the activities can be effectively used in the classroom. The length of these professional development opportunities range from two-hour sessions to several days, and can generally accommodate up to twenty

    This chart describes the Skylab student experiment (ED-63), Cytoplasmic Streaming, proposed by Cheryl A. Peitz of Arapahoe High School, Littleton, Colorado. Experiment ED-63 was to observe the effect of zero-gravity on cytoplasmic streaming in the aquatic plant named Elodea, commonly called water weed or water thyme. The phenomenon of cytoplasmic streaming is not well understood, but it is recognized as the circulation mechanism of the internal materials or cytoplasm of a cell. Cytoplasm is a gelatinous substance that has the ability to change its viscosity and flow, carrying various cell materials with it. The activity can be stimulated by sunlight or heat. In March 1972, NASA and the National Science Teachers Association selected 25 experiment proposals for flight on Skylab. Science advisors from the Marshall Space Flight Center aided and assisted the students in developing the proposals for flight on Skylab.

    Syncope may be the final common presentation of a number of clinical conditions spanning benign (i.e. neurally-mediated syncope) to life-threatening diseases (i.e. cardiac syncope). Hospitalization rate after a syncopal episode is high. An effective risk stratification is crucial to identify patients at risk of poor prognosis in the short term period to avoid unnecessary hospital admissions. The decision to admit or discharge a syncope patient from the ED is often based on the physician's clinical judgment. In recent years, several prognostic tools (i.e. clinical prediction rules and risk scores) have been developed to provide emergency physicians with accurate guidelines for hospital admission. At present, there are no compelling evidence that prognostic tools perform better than physician's clinical judgment in assessing the short-term outcome of syncope. However, the risk factors characterizing clinical prediction rules and risk scores may be profitably used by emergency doctors in their decision making, specifically whenever a syncope patient has to be discharged from ED or admitted to hospital. Patients with syncope of undetermined etiology, who are characterized by an intermediate-high risk profile after the initial evaluation, should be monitored in the ED. Indeed, data suggest that the 48h following syncope are at the highest risk for major adverse events. A new tool for syncope management is represented by the Syncope Unit in the ED or in an outpatient setting. Syncope Unit may reduce hospitalization and length of hospital stay. However, further studies are needed to clarify whether syncope patients' prognosis can be also improved. PMID:24811585

    The Regional Energy Deployment System (ReEDS) is a deterministic optimization model of the deployment of electric power generation technologies and transmission infrastructure throughout the contiguous United States into the future. The model, developed by the National Renewable Energy Laboratory's Strategic Energy Analysis Center, is designed to analyze the critical energy issues in the electric sector, especially with respect to potential energy policies, such as clean energy and renewable energy standards or carbon restrictions. ReEDS provides a detailed treatment of electricity-generating and electrical storage technologies and specifically addresses a variety of issues related to renewable energy technologies, including accessibility and cost of transmission, regional quality of renewable resources, seasonal and diurnal generation profiles, variability of wind and solar power, and the influence of variability on the reliability of the electrical grid. ReEDS addresses these issues through a highly discretized regional structure, explicit statistical treatment of the variability in wind and solar output over time, and consideration of ancillary services' requirements and costs.

  5. EDS coal liquefaction process development. Phase V. EDS Consolidation Program: flushing and blowdown system design

    1984-01-01

    The flushing and blowdown system of an EDS plant provides the means of removing viscous coal products and slurry streams from plant vessels and lines. In addition, it provides the flushing oil needed during normal operations for purging instruments in slurry service, for flushing slurry pump and slurry agitator seals, and for flushing slurry safety valve inlet lines. It contains a blowdown system for collecting material from washing operations, including the transport of the collected material to slop tankage. The rerun options for depleting the inventory of collected slop are a related aspect of the flushing and blowdown system design although specific equipment for handling slop is not part of the flushing and blowdown system facilities. This report documents the results of a study which evaluates the flushing and blowdown requirements for a commercial-scale EDS plant. The work was conducted as part of the EDS Consolidation Program. The design recommendations represent a consolidation of learnings accrued during previous phases of the EDS Project including results obtained from ECLP operations, from the ECLP Test Program, and from past EDS Study Design preparations. 1 reference, 4 figures, 2 tables.

    HHT shows clinical variability within and between families. Organ site and prevalence of arteriovenous malformations (AVMs) depend on the HHT causative gene and on environmental and genetic modifiers. We tested whether variation in the functional ENG allele, inherited from the unaffected parent, alters risk for pulmonary AVM in HHT1 mutation carriers who are ENG haploinsufficient. Genetic association was found between rs10987746 of the wild type ENG allele and presence of pulmonary AVM [relative risk = 1.3 (1.0018–1.7424)]. The rs10987746-C at-risk allele associated with lower expression of ENG RNA in a panel of human lymphoblastoid cell lines (P = 0.004). Moreover, in angiogenically active human lung adenocarcinoma tissue, but not in uninvolved quiescent lung, rs10987746-C was correlated with expression of PTPN14 (P = 0.004), another modifier of HHT. Quantitative TAQMAN expression analysis in a panel of normal lung tissues from 69 genetically heterogeneous inter-specific backcross mice, demonstrated strong correlation between expression levels of Eng, Acvrl1, and Ptpn14 (r2 = 0.75–0.9, P < 1 × 10−12), further suggesting a direct or indirect interaction between these three genes in lung in vivo. Our data indicate that genetic variation within the single functional ENG gene influences quantitative and/or qualitative differences in ENG expression that contribute to risk of pulmonary AVM in HHT1, and provide correlative support for PTPN14 involvement in endoglin/ALK1 lung biology in vivo. PTPN14 has been shown to be a negative regulator of Yap/Taz signaling, which is implicated in mechanotransduction, providing a possible molecular link between endoglin/ALK1 signaling and mechanical stress. EMILIN2, which showed suggestive genetic association with pulmonary AVM, is also reported to interact with Taz in angiogenesis. Elucidation of the molecular mechanisms regulating these interactions in endothelial cells may ultimately provide more rational choices for HHT

    2014-01-01

    The synthesis of ribosomes is an essential process, which is aided by a variety of transacting factors in bacteria. Among these is a group of GTPases essential for bacterial viability and emerging as promising targets for new antibacterial agents. Herein, we describe a robust high-throughput screening process for inhibitors of one such GTPase, the Escherichia coli EngA protein. The primary screen employed an assay of phosphate production in 384-well density. Reaction conditions were chosen to maximize sensitivity for the discovery of competitive inhibitors while maintaining a strong signal amplitude and low noise. In a pilot screen of 31,800 chemical compounds, 44 active compounds were identified. Further, we describe the elimination of non-specific inhibitors that were detergent-sensitive or reactive as well as those that interfered with the high-throughput phosphate assay. Four inhibitors survived these common counter-screens for non-specificity but these chemicals were also inhibitors of the unrelated enzyme dihydrofolate reductase, suggesting that they too were promiscuously active. The high-throughput screen of the EngA protein described here provides a meticulous pilot study in the search for specific inhibitors of GTPases involved in ribosome biogenesis. PMID:23606650

    The increasing use of array-CGH in malformation syndromes with intellectual disability could lead to the description of new contiguous gene syndrome by the analysis of the gene content of the microdeletion and reverse phenotyping. Thanks to a national and international call for collaboration by Achropuce and Decipher, we recruited four patients carrying de novo overlapping deletions of chromosome 9q33.3q34.11, including the STXBP1, the LMX1B and the ENG genes. We restrained the selection to these three genes because the effects of their haploinsufficency are well described in the literature and easily recognizable clinically. All deletions were detected by array-CGH and confirmed by FISH. The patients display common clinical features, including intellectual disability with epilepsy, owing to the presence of STXBP1 within the deletion, nail dysplasia and bone malformations, in particular patellar abnormalities attributed to LMX1B deletion, epistaxis and cutaneous-mucous telangiectasias explained by ENG haploinsufficiency and common facial dysmorphism. This systematic analysis of the genes comprised in the deletion allowed us to identify genes whose haploinsufficiency is expected to lead to disease manifestations and complications that require personalized follow-up, in particular for renal, eye, ear, vascular and neurological manifestations.

  12. Passive damping in EDS maglev systems.

    2002-05-03

    There continues to be strong interest in the subjects of damping and drag forces associated with electrodynamic suspension (EDS) systems. While electromagnetic drag forces resist the forward motion of a vehicle and therefore consume energy, damping forces control, at least in part, the response of the vehicle to disturbances. Ideally, one would like to reduce the drag forces as much as possible while retaining adequate damping forces to insure dynamic stability and satisfactory ride quality. These two goals turn out to be difficult to achieve in practice. It is well known that maglev systems tend to be intrinsically under damped. Consequently it is often necessary in a practical system design to enhance the damping passively or actively. For reasons of cost and simplicity, it is desirable to rely as much as possible on passive damping mechanisms. In this paper, rough estimates are made of the passive damping and drag forces caused by various mechanisms in EDS systems. No attention will be given to active control systems or secondary suspension systems which are obvious ways to augment passive damping mechanisms if the latter prove to be inadequate.

  13. Text message program improves outcomes, decreases ED utilization among ED patients with poorly controlled diabetes.

    2014-02-01

    Diabetic patients who lack access to primary care tend to frequent the ED, often with complications from their disease that could have been prevented with proper management and education. To get around the problem of access, researchers tested an automated program that continuously delivered educational messaging via text to a group of patients who presented to the ED with poorly controlled diabetes. After six months, researchers noted improvements in Hb A1c levels, self-reported medication adherence, and ED utilization when compared with a control group. And the impact was particularly noteworthy among Latinos, according to the researchers. The text messaging program, dubbed TExT-Med, was developed by four physicians and two diabetes educators. The messages were delivered daily, and contained educational as well motivational content derived from the National Diabetes Education Program.There were also medication reminders, healthy living challenges, and trivia questions about diabetes. At six months, Hb A1c levels decreased by 1.05% in the intervention group, compared to 0.60% in the control group, and self-reported medication adherence improved from 4.5 to 5.4 (as measured on an 8 point scale) in the intervention group versus a decrease of 0.1 in the control group. During the six-month study period, 35.9% of patients in the intervention group presented to the ED for care, as compared to 51.6% of patients in the control group. PMID:24505864

Goddard launched his liquid-fueled rockets in the 1920's to the more sophisticated space systems of the day. It was necessary to design fluid-flow systems that would not only overcome the lack of gravity but also overcome, or take advantage of, the effect of surface tension.

    Emergency department (ED) practices are traditionally profiled in terms of their patient encounters. Such evaluations reflect a preponderance of outpatient visits while crediting income from admitted patients to traditional hospital-based services. This study evaluates the contribution of ED admissions to inpatient hospital revenue. The study was set at an urban tertiary care community hospital with university affiliation. Information referable to ED patients was collected from the hospital's Universal Billing Code (UB-92)-based patient information warehouse. Data fields referable to hospital charges, insurance type, and disposition were used for analysis of a 1-year period from September 1, 1998 to August 31, 1999. Statistical analysis was through chi square and ANOVA. During the study period 33,174 patients were treated in the ED with 6,671 (20%) admitted to inpatient services. Total hospital charges for all ED patients during this time were $107 million dollars with $9.1 million (8.5%) generated from discharged patients and $98.0 million (91.5%) from admitted ED patients (P <.001). Mean charges for individual discharged patients were $344.10 whereas for individual admitted patients mean charges were $14,692.28. (P <.001) Medicaid and self pay represented 55.4% of the insurance coverage for discharged ED patients whereas these same insurance classes accounted for only 16.3% of admitted patients. (P <.001) Medicare visits accounted for 12.7% of discharged ED patients but 60.7% of admitted patients (P <.001). Total hospital gross revenue for inpatient services for the study period was $288 million of which 34% was contributed from admitted ED patients. ED services represent a major source of inpatient hospital revenue. The recognition of the ED's potential in this area may be lost if income from patients admitted through the ED is credited to traditional hospital-based services. PMID:11781909

    Patients dissatisfied with long waits is one of the most pressing problems that emergency department (ED) managers must address, and there is a trend of EDs offering service guarantees to patients to obtain higher satisfaction scores. At participating EDs, patients are offered letters of apology, movie passes, or a free visit if the guarantee isn't met. Census increased dramatically after the guarantee programs were implemented. To ensure the guarantees are met, additional nursing staff or ED beds may need to be added. PMID:12515111

    Introduction Differentiation between patients with acute cholecystitis and patients with severe biliary colic can be challenging. Patients with undiagnosed acute cholecystitis can incur repeat emergency department (ED) visits, which is resource intensive. Methods Billing records from 2000 – 2013 of all adults who visited the ED in the 30 days preceding their cholecystectomy were analyzed. Patients who were discharged from the ED and underwent elective cholecystectomy were compared to those who were discharged and returned to the ED within 30 days. T-tests, chi-square tests and multivariable analysis were utilized as appropriate. Results From 2000 - 2013, 3138 patients (34%) presented to the ED within 30 days prior to surgery, 63% were women, mean age 51 years, and of those 1625 were directly admitted from the ED for cholecystectomy while 1513 patients left the ED to return for an elective cholecystectomy. Patients who were discharged were younger (mean age 49 vs 54 yrs, p<0.001) and had shorter ED stays (5.9 vs 7.2 hrs, p<0.001) than the patients admitted immediately. Of the discharged patients, 303 (20%) returned to the ED within 30 days to undergo urgent cholecystectomy. Compared to patients with successful elective cholecystectomy after the ED visit, those who failed the pathway were more likely to have an ASA score > 3 and were <40 or ≥60 compared to the successful group. Conclusions One in five patients failed the elective cholecystectomy pathway after ED discharge, leading to additional patient distress and use of resources. Further risk factor assessment may help design efficient care pathways. PMID:25043530

    The performance of mental alerting during caloric testing has always been considered important, however its use/benefit during electronystagmography (ENG)/videonystagmography (VNG) testing has been questioned. The aim of this study was to investigate the effect of mental alerting tasks on peripheral type vestibular nystagmus recorded during ENG. Thirty patients with significant spontaneous/gaze or positional nystagmus (slow phase velocity >or= 6 degrees /s) were recruited from consecutive referrals for vestibular assessment. Nystagmus was recorded by ENG both in the presence and absence of mental alerting for each patient. Investigation of nystagmus by analysis of variance (ANOVA) revealed significantly larger nystagmus (higher value SPV) with mental alerting than with no alerting (p<0.001), and for some patients nystagmus traces were reduced to a flat line (no nystagmus) with no alerting. The study demonstrates the importance of mental alerting in helping overcome central suppression of nystagmus and highlights its importance to help identify peripheral type nystagmus during ENG.

    Judith S. Miles of Lexington High School, Lexington, Massachusetts, proposed skylab student experiment ED-52, Web Formation. This experiment was a study of a spider's behavior in a weightless environment. The geometrical structure of the web of the orb-weaving spider provides a good measure of the condition of its central nervous system. Since the spider senses its own weight to determine the required thickness of web material and uses both the wind and gravity to initiate construction of its web, the lack of gravitational force in Skylab provided a new and different stimulus to the spider's behavioral response. Two common cross spiders, Arabella and Anita, were used for the experiment aboard the Skylab-3 mission. After initial disoriented attempts, both spiders produced almost Earth-like webs once they had adapted to weightlessness. This photograph is of Arabella, a cross spider, in her initial attempt at spirning a web. This picture was taken by the crew of the Skylab 3 mission before Arabella adapted to her new environment.

Previously we used a series of still diffraction patterns to determine the structure of lysozyme at 2.9 Å resolution with MicroED (Shi et al., 2013). Here we present the structure of bovine liver catalase determined from a single crystal at 3.2 Å resolution by MicroED. The data were collected by continuous rotation of the sample under constant exposure and were processed and refined using standard programs for X-ray crystallography. The ability of MicroED to determine the structure of bovine liver catalase, a protein that has long resisted atomic analysis by traditional electron crystallography, demonstrates the potential of this method for structure determination.

    This paper traces the development of the Ed.D., explores the purposes the degree serves, and assesses its value. The creation of the degree stemmed largely from the reluctance of faculty in Arts and Sciences to offer the Ph.D. in professional schools.

  11. Community paramedics fill gaps, take load off EDs.

    PubMed

    2014-03-01

    In a continuing effort to ease demand on busy EDs, some communities are coming up with new ways to leverage paramedics. Under a three-year pilot program in Raleigh, NC, a select group of paramedics with added training are being used to assess patients with mental health or addiction problems and transfer them to alternative facilities when appropriate. In Robbinsdale, MN, a community paramedicine program is filling in care gaps for patients with chronic diseases and other complaints who are at risk for repeat ED visits or inpatient hospitalizations. * Administrators of the Raleigh, NC, program say that in 2013, paramedics diverted more than 300 patients to alternative facilities. Of these, only 20% to 25% need further transport to the hospital. * Every time the NC paramedics divert a patient from the ED to an alternative facility, they return an estimated 14 bed-hours back to the ED. * In addition to responding to patients with non-urgent needs, the Robbinsdale, MN, community paramedicine program is a referral source for ED physicians who are concerned about follow-up care for patients who have presented to the ED with medical problems that require ongoing attention.

    As an ED manager, you face the growing challenge of your performance data being shared with the public and with hospital administration. Be sure to share the good news with your administration, so they can use it to help market the hospital. When adverse rankings appear, you have two options: Seek additional resources to improve performance, or challenge the data. Use an automated system to access"real-time"data on your department's performance, so you will always be ready to defend your ED. PMID:20853578

    A central hypothesis of The Etiology, Risk Factors and Interactions of Enteric Infections and Malnutrition and the Consequences for Child Health and Development (MAL-ED) study is that enteropathogens contribute to growth faltering. To examine this question, the MAL-ED network of investigators set out to achieve 3 goals: (1) develop harmonized protocols to test for a diverse range of enteropathogens, (2) provide quality-assured and comparable results from 8 global sites, and (3) achieve maximum laboratory throughput and minimum cost. This paper describes the rationale for the microbiologic assays chosen and methodologies used to accomplish the 3 goals. PMID:25305291

    In this work, Automated Scanning Electron Microscopy with Energy Dispersive X-ray Spectrometry (SEM-EDS) was used to characterize 7.65 and 9mm cartridges Turkish ammunition. All samples were analyzed in a SEM Jeol JSM-5600LV equipped BSE detector and a Link ISIS 300 (EDS). A working distance of 20mm, an accelerating voltage of 20 keV and gunshot residue software was used in all analysis. Automated search resulted in a high number of particles analyzed containing gunshot residues (GSR) unique elements (PbBaSb). The obtained data about the definition of characteristic GSR particles was concordant with other studies on this topic.

    2003-05-01

    Today the method commonly used for detecting gunshot residue is through the combined use of scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). In recent years, this same methodology began to find use in detecting and characterizing pyrotechnic reaction residue (PRR) particles whether produced by explosion or burning. This is accomplished by collecting particulate samples from a surface in the immediate area of the pyrotechnic reaction. Suspect PRR particles are identified by their morphology (typically 1 to 20 microm spheroidal particles) using an SEM; then they are analyzed for the elements they contain using X-ray EDS. This can help to identify the general type of pyrotechnic composition involved. PMID:12762523

    2008-10-01

    Dennis Parsons Burkitt was an accomplished Irish surgeon who was headed for a life of luxury. However, he opted for a more meaningful calling and pursued missionary work in Africa instead. While there, he came across an extraordinary pediatric jaw tumor that was not only disfiguring, but also rapidly fatal. Despite the futility of surgery, he became captivated with studying this unrecognized malignancy and conducted what is considered to be one of the most formidable epidemiologic investigations in the history of cancer research by surveying the entire continent. Without any formal training in research, it would be his simple passion to learn that led him to unravel the mysteries behind a new form of non-Hodgkin lymphoma that currently bears his name. Through his spirit for collaboration, effective forms of treatment were ultimately discovered for this most common pediatric malignancy in Africa. PMID:19011473

    In May, prior to the start of the 2012 hurricane season, AGU asked us to write an op-ed for the Houston Chronicle on the importance of funding hurricane research. We were excited to be asked and pleased that AGU facilitated the process by providing us with some guidance on writing the op-ed. Given the impact that Hurricane Ike had in Texas just a few years ago, we felt it was important to remind the citizens of the greater Houston metropolitan area of the societal benefits of funding hurricane research. Thanks to the assistance of AGU staff, writing the article required only a few hours of time. Our op-ed was published in the print edition of the Houston Chronicle on 1 June 2012, the official start of the hurricane season (http://www.chron.com/default/article/Tight-budgets-posing-threat-to-Texas-hurricane-3600363.php). It was picked up by the media relations office in the College of Geosciences at Texas A&M University and featured on the college's Web site in the dean's biweekly briefing and on its Facebook page. As a result, the op-ed reached a large and diverse audience.

    2009-02-01

    This was a study of 157,028 emergency department (ED)-diagnosed visits for chest pain (International Classification of Diseases, Ninth Revision [ICD-9]: 786) in 6 cities in Canada. The generalized linear mixed methods technique was applied to analyze the relations between daily counts of ED visits for chest pain on the levels of ambient air pollutants after adjusting for meteorological variables. The daily counts of visits were analyzed separately for the whole period (January-December), warm (April-September), and cold (October-March). The results are presented in the form of the excess risks associated with an increase in the mean values of the pollutant concentrations. The highest increase was obtained for nitrogen dioxide (NO2) exposure in the warm period as follows: 5.9% (95% confidence interval, 3.3-5.8) for mean value equals to 20.1 ppb. The associations of ED visits for chest pain with air pollution are very similar to the associations of ED visits related to cardiac problems. PMID:19371523

This discussion suggests that neither is favoured over the other. Indeed, for distributions where both exist, they may be found in terms of each other, either by an analytical expression or by numerical calculation.

    technologies; and international obligations attendant to the Chemical Weapons Convention, which entered into force in 1997. Hermann Martens's presentation of German arsenical and mustard munitions and of technical approaches to their destruction is similarly detailed, thorough, and engaging. W. R. Cullen's chapter "Arsenic in the Environment" and Shigeru Maeda's chapter "Biotransformation of Arsenic in Freshwater Organisms" help place the problems associated with the arsenicals in their environmental context and, hence, should appeal to a large audiencenot merely those specialists dealing with chemical weapon destruction. The reports of the three discussion groupsYperite,3 Arsenicals, and Recovered Munitionsprovide useful summaries of current knowledge and needs for additional research. The Arsenicals report observes that "destruction of arsenical agents appears to have received little attention." This situation may change if searches in Washington, DC, should uncover caches of old arsenicals at CUA and, especially, when the governments of the People's Republic of China and Japan agree on funding for destruction of the chemical munitions Japan caused to be abandoned on what is now the territory of the PRC. A conservative estimate is that there are 2,000,000 of these abandoned munitions, most of them being arsenicals and mustards.4 Notes and References 1. Nieuwland (1878-1936) hired Rockne in 1914 as a chemistry instructor. According to Father Nieuwland, Rockne owed much of his prowess as one of the greatest coaches of all time to his training in chemistry, which taught him the method of reasoning (Ind. Eng. Chem. New Ed., April 20, 1931). W. Lee Lewis, Lewisite's eponym, credits Nieuwland's unpublished dissertation as the source for his 1918 synthesis (Lewis, W. L.; Perkins, G. A. The beta-Chlorovinyl Chloroarsines; Ind. Eng. Chem. 1923, 15, 290-295). Lewisite itself is actually the group of mono-, di-, and tri-substituted 2-chloroethenyl derivatives of arsenic(III) chloride

    2008-04-01

    Lean manufacturing techniques, first developed by Toyota, can be successfully adapted to help improve processes in your ED. St. Luke's Episcopal Hospital in Houston, has used Lean to reduce median length of stay, frequency of diversions, and the percentage of patients who left before treatment was complete (LBTC). Here's why "Lean" can help improve the performance of your ED: It enables you and your staff to see things from the patient's point of view. Lean tools enable you to view the status of your department in real-time and to compare that status with your performance goals. Exercises help identify areas where your processes break down and determine the most likely solutions. PMID:18689224

    In a hospital ED in Rhode Island, a 96-year-old patient was robbed of her jewelry while she rested in her room. The thief was dressed in scrubs. Identification badges are only one way of keeping unwanted intruders out and your patients' belongings safe. Other suggestions: Have different groups of staff members, i.e., ED doctors and nurses, wear color-coded scrubs that distinguish them from other hospital personnel. If your staff see a strangely dressed person or someone who looks lost or like they don't fit in, they should question them about their identity. Create protocols for the removal and safekeeping of patients' jewelry that cover several different scenarios. PMID:18198764

Ed served in the U.S. Navy from 1968 to 1983. He attended the U.S. Naval Test Pilot School and graduated in 1973. He was then assigned as an engineering test pilot, and as an instructor at the Naval Test Pilot School. He first arrived at what was then called the Ames-Dryden Flight Research Facility (now the Dryden Flight Research Center) as a Navy Liaison Officer on July 5, 1982. He joined NASA as a research pilot a year later. Ed was a project pilot on the F-18 High Angle-of-Attack program, the F-15 aeronautical research aircraft, the B-52 launch aircraft, and the NASA-operated SR-71 Blackbirds. Ed retired as a NASA research pilot in September 2000.

  3. Lean-driven solutions slash ED wait times, LOS.

    PubMed

    2012-12-01

    The ED at The Aroostook Medical Center (TAMC) in Presque Isle, ME, is a level II trauma center. It is the largest in the region, with only 89 beds. It has undergone a transformation in recent months, with average wait times to see a provider going from four to five hours down to less than five minutes, and the left-without-being-seen (LWBS) rate has been slashed from a high of 7% down to less than 1%. The hospital says the improvements are the result of lean-driven, staff-designed solutions, coupled with administrative engagement and oversight. And administrators say more improvements are on the way in 2013 when a hospital-wide workgroup will try to clear away obstacles and inefficiencies from the hospital admissions process. To tackle long wait times among patients with lower triage levels, the ED instituted a fast-track system, manned by mid-level providers and a tech or LPN. Responsibilities for charge nurses have been redesigned so that they have the power to monitor and facilitate patient flow. The ED has initiated more point-of-care testing so that nurses and techs can conduct many routine tests on their own. While the lean model relies on staff-driven solutions, administrators make the difference when it comes to sustaining changes and minimizing employee resistance. PMID:23214229

  4. States leverage telepsychiatry solutions to ease ED crowding, accelerate care.

    PubMed

    2015-02-01

    Many states are having success turning to telepsychiatry-based solutions to connect mental health patients with needed care while also decompressing crowded EDs. Just one year into a statewide telepsychiatry initiative in North Carolina (NC-STeP), administrators say the approach has saved as much as $7 million, and hospital demand for the service is higher than anticipated. In Texas, mental health emergency centers (MHEC) that use telepsychiatry to connect patients in rural areas with needed psychiatric care are freeing up EDs to focus on medical care. In just 11 months, 91 North Carolina hospitals have at least started the process to engage in NC-STeP. Much of the savings from NC-STeP come from involuntary commitment orders being overturned as a result of the telepsychiatry consults, reducing the need for expensive inpatient care. Implementing NC-STeP has involved multiple hurdles including credentialing difficulties and technical/firewall challenges. The Texas model provides 24/7 availability of psychiatrists via telemedicine through a network of MHECs. In-person staff at the MHECs perform basic screening tests and blood draws so that medical clearance can be achieved without the need for an ED visit in most cases. Funding for the MHECs comes from the state, hospitals in the region, and local governmental authorities that reap savings or benefits from the initiative. PMID:25688413

    PubMed

    2016-05-01

    The ED at Banner Payson Medical Center in Payson, AZ, has charted dramatic improvements on key metrics through a range of staff and policy changes. In just a few months, the ED has halved wait times, patient satisfaction has improved, and daily volume is up. Administrators say the secret to the success of the effort is a move to be transparent by posting key metrics regarding patient flow, a tactic that has helped the team pull together and feel a sense of accomplishment when performance goals are achieved. Administrators adjusted staff schedules to better match patient volume patterns in the ED, and they added staff to help nurses during peak hours. A new provider group enlisted the assistance of scribes during peak hours to manage the documentation workload while also enabling physicians to focus more patient interaction. Physicians hold end-of-shift huddles to review successes and challenges, and to improve physician/nurse communication. The tactic also helps develop the staff from an educational standpoint.

    2014-09-01

    This paper profiles the findings from a study that explored the perspectives and experiences of nurse educators who implemented a novel simulation approach termed Mask-Ed. The technique involves the educator wearing a silicone mask and or body parts and transforming into a character. The premise of this approach is that the masked educator has domain specific knowledge related to the simulation scenario and can transmit this to learners in a way that is engaging, realistic, spontaneous and humanistic. Nurse educators charged with the responsibility of implementing Mask-Ed in three universities were invited to participate in the study by attending an introductory workshop, implementing the technique and then journaling their experiences, insights and perspectives over a 12 month period. The journal entries were then thematically analysed. Key themes were categorised under the headings of Preparation, Implementation and Impact; Reflexivity and Responsiveness; Student Engagement and Ownership; and Teaching and Learning. Mask-Ed is a simulation approach which allows students to interact with the 'characters' in humanistic ways that promote person-centred care and therapeutic communication. This simulation approach holds previously untapped potential for a range of learning experiences, however, to be effective, adequate resourcing, training, preparation and practice is required.

    Zero Population Growth's Population Education (Pop Ed) program began in 1975 as an ongoing effort to bring the "real world" into the classroom by demonstrating the relationships among population trends, food and energy resources, and environmental and economic problems. The training workshops which last for a day or 2 have the following goals: 1) to offer a brief demographic overview for teachers, 2) to provide lesson plans and techniques readily usable in the classroom, 3) to alert teachers to the best written and audiovisual materials available, 4) to identify local resources for teaching Pop Ed, and 5) to provide sample materials. In the 1st year of program operation 10 workshops were held. These workshops are credited, at least partly, with the subsequent population instruction that reached over 10,400 students and 1600 teachers. Another 15 workshops were held in the 2nd year of operation. Obstacles to the program are the assumption on the part of some teachers that Pop Ed belongs in disciplines other than their own and the belief on the part of many teachers that they will require extensive training.

    Introduction Nausea and vomiting in pregnancy (NVP) is a condition that commonly affects women in the first trimester of pregnancy. Despite frequently leading to emergency department (ED) visits, little evidence exists to characterize the nature of ED visits or to guide its treatment in the ED. Our objectives were to evaluate the treatment of NVP in the ED and to identify factors that predict return visits to the ED for NVP. Methods We conducted a retrospective database analysis using the electronic medical record from a single, large academic hospital. Demographic and treatment variables were collected using a chart review of 113 ED patient visits with a billing diagnosis of “nausea and vomiting in pregnancy” or “hyperemesis gravidarum.” Logistic regression analysis was used with a primary outcome of return visit to the ED for the same diagnoses. Results There was wide treatment variability of nausea and vomiting in pregnancy patients in the ED. Of the 113 patient visits, 38 (33.6%) had a return ED visit for NVP. High gravidity (OR 1.31, 95% CI [1.06–1.61]), high parity (OR 1.50 95% CI [1.12–2.00]), and early gestational age (OR 0.74 95% CI [0.60–0.90]) were associated with an increase in return ED visits in univariate logistic regression models, while only early gestational age (OR 0.74 95% CI [0.59–0.91]) was associated with increased return ED visits in a multiple regression model. Admission to the hospital was found to decrease the likelihood of return ED visits (p=0.002). Conclusion NVP can be difficult to manage and has a high ED return visit rate. Optimizing care with aggressive, standardized treatment in the ED and upon discharge, particularly if factors predictive of return ED visits are present, may improve quality of care and reduce ED utilization for this condition.

    Scanning electron microscopy in combination with energy-dispersive X-ray spectrometry (SEM/EDS) is a proven forensic tool and has been used to analyze several kinds of trace evidence. A forensic application of SEM/EDS is the examination of morphological characteristics of tool marks that tools and instruments leave on bone. The microtraces that are left behind by these tools and instruments on the bone are, however, often ignored or not noticed at all. In this paper we will describe the use of SEM/EDS for the analysis of microtraces in invasive sharp-force, blunt-force and bone-hacking traumas in bone. This research is part of a larger multi-disciplinary approach in which pathologists, forensic anthropologists, toolmark and microtrace experts work together to link observed injuries to a suspected weapon or, in case of an unknown weapon, to indicate a group of objects that could have been used as a weapon. Although there are a few difficulties one have to consider, the method itself is rather simple and straightforward to apply. A sample of dry and clean bone is placed into the SEM sample chamber and brightness and contrast are set such that bone appears grey, metal appears white and organic material appears black. The sample is then searched manually to find relevant features. Once features are found their elemental composition is measured by an energy dispersive X-ray spectrometer (EDS). This method is illustrated using several cases. It is shown that SEM/EDS analysis of microtraces in bone is a valuable tool to get clues about an unknown weapon and can associate a specific weapon with injuries on the basis of appearance and elemental composition. In particular the separate results from the various disciplines are complementary and may be combined to reach a conclusion with a stronger probative value. This is not only useful in the courtroom but above all in criminal investigations when one have to know for what weapon or object to look for. PMID:21871744

    The objectives of the Study Design Update (SDU) were to identify the technical issues facing a potential commercial-size EDS plant design; to provide a reliable basis for estimating the cost of EDS products; and to furnish research guidance to the EDS Project. The SDU consists of two distinct studies in which different processing schemes are used to produce the hydrogen and fuel gas required by the plant. These studies are referred to as the Base Case and the Market Flexibility Sensitivity Case. In the Base Case, hydrogen is generated by steam reforming of the light hydrocarbon gases produced in the plant. Fuel gas is generated by feeding the bottoms stream from the liquefaction section vacuum pipestill to a FLEXICOKING unit. In the FLEXICOKING unit reactor, the bottoms stream is converted to coke; additional liquid product is also recovered. The coke is converted to low-Btu fuel gas in the FLEXICOKING unit gasifier. In the Market Flexibility Sensitivity (MFS) Case, the bottoms stream from the vacuum pipestill is split, and about half is sent to the FLEXICOKING unit for recovery of additional liquid product and production of fuel gas. The remainder of the bottoms stream is converted to hydrogen in a Partial Oxidation Unit. Hence the MFS Case does not consume light hydrocarbon gases produced and they are available for sale. The study of these two cases has demonstrated the importance of bottoms process selection to the economics and thermal efficiency of an EDS plant. Volume 1 - Main Report has been developed to be a stand-alone document. Both the Base Case and Market Flexibility Sensitivity (MFS) Case are covered. This volume includes an overview and detailed case summaries. It also covers economics, product recovery factors, material and energy balances, cost estimates and enviromental considerations.

    Hazardous materials (hazmat) events pose a health threat not only for those individuals in the immediate vicinity of the release (ie, members of the general public, on-site first responders, employees), but also for ED personnel (ie, physicians and nurses) treating the chemically contaminated victims arriving at the hospital. Secondary contamination injuries to ED personnel result when exposed victims enter the ED without being properly decontaminated. Data from the Agency for Toxic Substances and Disease Registry's Hazardous Substances Emergency Events Surveillance System were used to conduct a retrospective analysis on hazmat events occurring in 16 states from 1995 through 2001 that involved secondary injury to ED personnel. Six events were identified in which 15 ED personnel were secondarily injured while treating contaminated victims. The predominant injuries sustained were respiratory and eye irritation. Proper victim decontamination procedures, good field-to-hospital communication, and appropriate personal protective equipment (PPE) use can help prevent ED personnel injuries and contamination of the ED.

    2010-12-01

    Ambient particulate matter (PM) samples were collected with UNC passive samplers during agricultural burns in Imperial Valley, California. Four Bermuda grass field burn events were sampled at 3-8 locations surrounding each burn. Sampling began at the start of each burn (30-60 min) and continued for 24-120 hours. During 3 of the 4 burn events, winds were calm and plumes were observed to travel straight up to the inversion layer. In one event, winds created a ground-level plume that enveloped two UNC samplers mounted on telephone poles very close to the field (0.2-0.3 miles away). Computer-controlled scanning electron microscopy / energy-dispersive x-ray spectroscopy (CCSEM/EDS) was used to measure particle sizes and elemental composition, from which mass concentrations and size distributions were calculated. The median PM2.5 and PM10 levels measured in this study were 3.4 and 20 ug/m3, respectively. To determine quantitative accuracy, UNC sampler PM2.5 results (PM< 2.5 um) were compared to PM2.5 results from four co-located, continuous-reading beta-attenuation monitors (EBAMs). The median agreement (EBAM - UNC) was 3.8 ug/m3. Manual SEM/EDS detected various distinctive species in these samples, including sea salt, spores, plant fragments, and large soot agglomerates. During the ‘plume event’, 24-hour PM2.5 exposures downwind were up to 17 times higher than that measured upwind. Numerous submicron combustion particles with carbon and oxygen only were directly observed by manual SEM/EDS in the two plume-impacted samples, along with larger ash particles enriched in potassium, sulfur, chlorine, calcium, sodium, and phosphorus. CCSEM/EDS data from this event was grouped into 5 particle classes to generate size-fraction-specific pie charts. Burn-related particle types contributed 95% of the PM2.5 in the location directly impacted by the ground-level plume, compared to only 12% in the upwind location.

    1997-05-01

    Conventional reinforced concrete designs will have to be altered when designing a guideway for a maglev using an electrodynamically suspended (EDS) propulsion system. This type of propulsion system generates large magnetic fields that will develop magnetically induced, circulating eddy currents in any conventional steel reinforcement in close proximity to the magnets. These eddy currents, if large enough, may produce significant power losses that could adversely effect operation of the system. This paper presents a method and explanation for civil engineers to use for estimating the power losses due to the presence of metallic reinforcement. This procedure may be used to help guide future designs in the selection and placement of reinforcing material.

    The purpose of this study was to examine the emergency department (ED) management of hypothermic cardiac arrest and its outcome. The medical records of all patients with hypothermic cardiac arrest treated in the ED from January 1, 1988 to January 31, 1999 were retrospectively reviewed. Data collected included initial body temperature, serum potassium, methods of rewarming, return of perfusing rhythm, and morbidity and mortality. Data were analyzed by descriptive methods. Eleven patients were treated in the ED resuscitation room for hypothermic cardiac arrest. Six patients were found in cardiac arrest in the field, one patient arrested during transport, and four patients arrested after ED arrival. The average initial temperature was 79.1 degrees F (range 69.0 degrees F to 86.7 degrees F). Seven patients received an ED thoracotomy with internal cardiac massage and warm mediastinal irrigation. Four patients had airway management in the ED and then direct transport to the operating room for cardiac bypass rewarming. Three of the seven patients who received an ED thoracotomy subsequently went to intraoperative cardiac bypass rewarming. Five of the seven (71.4%) patients who received an ED thoracotomy survived, versus none of the four patients (0%) who went directly to intraoperative cardiac bypass. A direct comparison of immediate ED thoracotomy versus intraoperative cardiac bypass without ED thoracotomy is cautiously made as this was an unmatched and nonrandomized study. Three of the surviving patients underwent intraoperative cardiac bypass rewarming after receiving an ED thoracotomy. In two of these patients a perfusing rhythm had been established after thoracotomy in the ED and before transport to the operating room for cardiac bypass. Only one of seven (14.3%) patients who arrested prehospital survived versus four of four (100%) who arrested in the ED. ED thoracotomy with internal cardiac massage and mediastinal irrigation rewarming is effective in the management

    The formation of large, well-ordered crystals for crystallographic experiments remains a crucial bottleneck to the structural understanding of many important biological systems. To help alleviate this problem in crystallography, we have developed the MicroED method for the collection of electron diffraction data from 3D microcrystals and nanocrystals of radiation-sensitive biological material. In this approach, liquid solutions containing protein microcrystals are deposited on carbon-coated electron microscopy grids and are vitrified by plunging them into liquid ethane. MicroED data are collected for each selected crystal using cryo-electron microscopy, in which the crystal is diffracted using very few electrons as the stage is continuously rotated. This protocol gives advice on how to identify microcrystals by light microscopy or by negative-stain electron microscopy in samples obtained from standard protein crystallization experiments. The protocol also includes information about custom-designed equipment for controlling crystal rotation and software for recording experimental parameters in diffraction image metadata. Identifying microcrystals, preparing samples and setting up the microscope for diffraction data collection take approximately half an hour for each step. Screening microcrystals for quality diffraction takes roughly an hour, and the collection of a single data set is ∼10 min in duration. Complete data sets and resulting high-resolution structures can be obtained from a single crystal or by merging data from multiple crystals. PMID:27077331

  2. ACOs: time for ED managers to get involved, shape how their departments will add value.

    2011-06-01

    Even with a proposed rule outlining how accountable care organizations (ACO) will be structured under fee-for-service Medicare, emergency medicine experts are concerned about how ACOs will impact patient access to the ED. Further, some see a clear need to beef-up case management staff, while others say ED managers need to get involved with ACO-development now so their interests and concerns are represented. Under a proposed rule unveiled by the Department of Health and Human Services, a handful of quality indicators will require the tracking of ED visits related to certain ambulatory care-sensitive conditions; experts say it could be a challenge for ED staff to differentiate between appropriate and inappropriate use of the ED. EDs that figure out how to contribute value under the ACO mission will be better positioned to prosper under the new model. The ACO model is likely to add considerable complexity to billing and reimbursement. PMID:21675150

    A magnetic vibration simulator is one of the most important test tools to evaluate the basic performance of superconducting magnet (SCM) for EDS maglev. In this paper, we propose a new magnetic vibration simulator which can also suspend car and bogie mounted with the SCMs to evaluate the performance of not only SCMs but also vehicle dynamics with levitation. This system is composed of magnetic exciting coils which can simultaneously suspend and vibrate the SCMs and inverters which can simultaneously control 3-phase and zero-phase currents. This paper describes the principle, analytical method and control method of this system, and using numerical example, the vehicle dynamics and the vibration response of SCM are revealed.

    The V25 containment vessel was procured by the Project Manager, Non-Stockpile Chemical Materiel (PMNSCM) as a replacement vessel for use on the P2 Explosive Destruction Systems. It is the first EDS vessel to be fabricated under Code Case 2564 of the ASME Boiler and Pressure Vessel Code, which provides rules for the design of impulsively loaded vessels. The explosive rating for the vessel based on the Code Case is nine (9) pounds TNT-equivalent for up to 637 detonations. This limit is an increase from the 4.8 pounds TNT-equivalency rating for previous vessels. This report describes the explosive qualification tests that were performed in the vessel as part of the process for qualifying the vessel for explosive use. The tests consisted of a 11.25 pound TNT equivalent bare charge detonation followed by a 9 pound TNT equivalent detonation.

    Introduction Falls among older adults (aged ≥65 years) are the leading cause of both injury deaths and emergency department (ED) visits for trauma. We examine the characteristics and prevalence of older adult ED fallers as well as the recurrent ED visit and mortality rate. Methods This was a retrospective analysis of a cohort of elderly fall patients who presented to the ED between 2005 and 2011 at two urban, level-1 trauma, teaching hospitals with approximately 80,000-95,000 annual visits. We examined the frequency of ED revisits and death at 3 days, 7 days, 30 days, and 1 year controlling for certain covariates. Results Our cohort included 21,340 patients. The average age was 78.6. An increasing proportion of patients revisited the ED over the course of a year, ranging from 2% of patients at 3 days to 25% at 1 year. Death rates increased from 1.2% at 3 days to 15% at 1 year. 10,728 (50.2%) patients returned to the ED at some point during our 7-year study period and 36% of patients had an ED revisit or death within 1 year. In multivariate logistic regression, male sex and comorbidities were associated with ED revisits and death. Conclusion Over a third of older adult ED fall patients had an ED revisit or died within one year. Falls are one of the geriatric syndromes that contribute to frequent ED revisits and death rates. Future research should determine whether falls increase the risk of such outcomes and how to prevent future fall and death. PMID:25983268

    Membrane curvature and lipid composition plays a critical role in interchanging of matter and energy in cells. Peptide curvature sensors are known to activate signaling pathways and promote molecular transport across cell membranes. Recently, the 25-mer MARCKS-ED peptide, which is derived from the effector domain of the myristoylated alanine-rich C kinase substrate protein, has been reported to selectively recognize highly curved membrane surfaces. Our previous studies indicated that the naturally occurring L-MARCKS-ED peptide could simultaneously detect both phosphatidylserine and curvature. Here, we demonstrate that D-MARCKS-ED, composed by unnatural D-amino acids, has the same activities as its enantiomer, L-MARCKS-ED, as a curvature and lipid sensor. An atomistic molecular dynamics simulation suggests that D-MARCKS-ED may change from linear to a boat conformation upon binding to the membrane. Comparable enhancement of fluorescence intensity was observed between D- and L-MARCKS-ED peptides, indicating similar binding affinities. Meanwhile, circular dichroism spectra of D- and L-MARCKS-ED are almost symmetrical both in the presence and absence of liposomes. These results suggest similar behavior of artificial D- and natural L-MARCKS-ED peptides when binding to curved membranes. Our studies may contribute to further understanding of how MARCKS-ED senses membrane curvature as well as provide a new direction to develop novel membrane curvature probes. PMID:25851418

    Arbuscular mycorrhizal fungi (AMF), ubiquitous soil fungi that form symbiotic relationships with the majority of terrestrial plants, are known to play an important role in plant tolerance to chromium (Cr) contamination. However, the underlying mechanisms, especially the direct influences of AMF on the translocation and transformation of Cr in the soil-plant continuum, are still unresolved. In a two-compartment root-organ cultivation system, the extraradical mycelium (ERM) of mycorrhizal roots was treated with 0.05 mmol L(-1) Cr(VI) for 12 days to investigate the uptake, translocation, and transformation of Cr(VI) by AMF using inductively coupled plasma mass spectrometry (ICP-MS), scanning electron microscopy equipped with energy-dispersive spectroscopy (SEM-EDS), transmission electron microscopy equipped with energy-dispersive spectroscopy (TEM-EDS), and X-ray-absorption fine structure (XAFS) technologies. The results indicated that AMF can immobilize quantities of Cr via reduction of Cr(VI) to Cr(III), forming Cr(III)-phosphate analogues, likely on the fungal surface. Besides this, we also confirmed that the extraradical mycelium (ERM) can actively take up Cr [either in the form of Cr(VI) or Cr(III)] and transport Cr [potentially in the form of Cr(III)-histidine analogues] to mycorrhizal roots but immobilize most of the Cr(III) in the fungal structures. Based on an X-ray absorption near-edge spectroscopy analysis of Cr(VI)-treated roots, we proposed that the intraradical fungal structures can also immobilize Cr within mycorrhizal roots. Our findings confirmed the immobilization of Cr by AMF, which plays an essential role in the Cr(VI) tolerance of AM symbioses. PMID:26551890

    Loss of Control Eating Disorder (LOC-ED) has been proposed as a diagnostic category for children 6–12y with binge-type eating. However, characteristics of youth with LOC-ED have not been examined. We tested the hypothesis that the proposed criteria for LOC-ED would identify children with greater adiposity, more disordered eating attitudes, and greater mood disturbance than those without LOC-ED. Participants were 251 youth (10.29y ± 1.54, 53.8% female, 57.8 % White, 35.5% Black, 2.0% Asian, 4.8% Hispanic, 53.0% overweight). Youth were interviewed regarding eating attitudes and behaviors, completed questionnaires to assess general psychopathology, and underwent measurements of body fat mass. Using previously proposed criteria for LOC-ED, children were classified as LOC-ED (n = 19), LOC in the absence of the full disorder (subLOC, n = 33), and youth not reporting LOC (noLOC, n = 199). LOC-ED youth had higher BMIz (p = 0.001) and adiposity (p = 0.003) and reported greater disordered eating concerns (p < 0.001) compared to noLOC youth. Compared to subLOC youth, LOC-ED youth had non-significantly higher BMIz (p = 0.11), and significantly higher adiposity (p = 0.04) and disordered eating attitudes (p = 0.02). SubLOC youth had greater disordered eating concerns (p < 0.001) and BMIz (p = 0.03) but did not differ in adiposity (p = 0.33) compared to noLOC youth. These preliminary data suggest that LOC-ED youth are elevated on disordered eating cognitions and anthropometric measures compared to youth without LOC-ED. Longitudinal studies are needed to determine if those with LOC-ED are at particularly increased risk for progression of disordered eating and excess weight gain. PMID:25913008

Participants were 251 youth (10.29years±1.54, 53.8% female, 57.8% White, 35.5% Black, 2.0% Asian, 4.8% Hispanic, 53.0% overweight). Youth were interviewed regarding eating attitudes and behaviors, completed questionnaires to assess general psychopathology, and underwent measurements of body fat mass. Using previously proposed criteria for LOC-ED, children were classified as LOC-ED (n=19), LOC in the absence of the full disorder (subLOC, n=33), and youth not reporting LOC (noLOC, n=199). LOC-ED youth had higher BMIz (p=0.001) and adiposity (p=0.003) and reported greater disordered eating concerns (p<0.001) compared to noLOC youth. Compared to subLOC youth, LOC-ED youth had non-significantly higher BMIz (p=0.11), and significantly higher adiposity (p=0.04) and disordered eating attitudes (p=0.02). SubLOC youth had greater disordered eating concerns (p<0.001) and BMIz (p=0.03) but did not differ in adiposity (p=0.33) compared to noLOC youth. These preliminary data suggest that LOC-ED youth are elevated on disordered eating cognitions and anthropometric measures compared to youth without LOC-ED. Longitudinal studies are needed to determine if those with LOC-ED are at particularly increased risk for progression of disordered eating and excess weight gain. PMID:25913008

    Study Objective Atrial fibrillation (AF) is often first diagnosed in the emergency department (ED) and accounts for nearly 1% of all ED visits. Our objective was to assess the Framingham Heart Study risk score for AF development in ED patients with newly diagnosed AF. Methods We systematically reviewed the electronic medical records of ED patients with newly diagnosed AF between August 2005 and July 2008. We measured the frequency of the Framingham Heart Study predictors and calculated each patient's risk score. Results During the 3-year study period, 914 patients had 1228 ED visits. New AF was diagnosed in 296 (32%) patients. Among these patients, 107 (36%) were female, 127 (43%) had prior ED visits since 2003, 189 (64%) were taking hypertension medications and 170 (57.4%) had previous electrocardiograms with measurable PR intervals. The median PR interval was 166 ms (151 to 180) and 60% of available PR intervals were ≥160 ms. The median (Interquartile range) age, body mass index, and systolic blood pressure were 66 years (53 to 77), 27 (23 to 31), and 134 mm Hg (118 to 151), respectively. Median risk score was 7 (3 to 9) indicating high predicted risk. Heart failure and cardiac murmurs were previously diagnosed in 45 (15%) and 32 (11%) of these patients, respectively. Conclusions The Framingham risk factors for AF are commonly encountered among ED patients with newly diagnosed AF. The ED might provide an opportunity to identify patients at high risk for AF and refer them for primary prevention interventions. PMID:21208770

    We conducted a pre- and postintervention analysis to assess the impact of a process improvement project at the Cambridge Hospital ED. Through a comprehensive and collaborative process, we reengineered the emergency patient experience from arrival to departure. The ED operational changes have had a significant positive impact on all measured metrics. Ambulance diversion decreased from a mean of 148 hours per quarter before changes in July 2006 to 0 hours since April 2007. ED total length of stay decreased from a mean of 204 minutes before the changes to 132 minutes. Press Ganey patient satisfaction scores rose from the 12th percentile to the 59th percentile. ED patient volume grew by 11%, from a mean of 7,221 patients per quarter to 8,044 patients per quarter. Compliance with ED specific quality core measures improved from a mean of 71% to 97%. The mean rate of ED patients that left without being seen (LWBS) dropped from 4.1% to 0.9%. Improving ED operational efficiency allowed us to accommodate increasing volume while improving the quality of care and satisfaction of the ED patients with minimal additional resources, space, or staffing.

    Membrane curvature and lipid composition regulate important biological processes within a cell. Currently, several proteins have been reported to sense and/or induce membrane curvatures, e.g. Synaptotagmin-1 and Amphiphysin. However, the large protein scaffold of these curvature sensors limits their applications in complex biological systems. Our interest focuses on identifying and designing peptides that can sense membrane curvature based on established elements observed in natural curvature-sensing proteins. Membrane curvature remodeling also depends on their lipid composition, suggesting strategies to specifically target membrane shape and lipid components simultaneously. We have successfully identified a 25-mer peptide, MARCKS-ED, based on the effector domain sequence of the intracellular membrane protein myristoylated alanine-rich C-kinase substrate that can recognize PS with preferences for highly curved vesicles in a sequence specific manner. These studies further contribute to the understanding of how proteins and peptides sense membrane curvature, as well as provide potential probes for membrane shape and lipid composition.

    Study Objective To determine the ability of emergency department (ED) physicians to diagnose cholelithiasis with bedside ultrasound. Methods ED gallbladder ultrasounds recorded over 37 months were compared to radiology ultrasound interpretation. Results Of 1,690 ED gallbladder ultrasound scans performed during this period, radiology ultrasound was performed in 575/1690 (34%) cases. ED physician bedside interpretation was 88% sensitive [95% CI, 84–91] and 87% specific [95% CI, 82–91], while positive predictive value (PPV) was 91% [88–94%] and negative predictive value (NPV) was 83% [78–87%], using radiology interpretation as the criterion reference. Conclusion ED physician ultrasound of the gallbladder for cholelithiasis is both sensitive and specific. PMID:19561694

    2016-01-01

    Microelectron diffraction (MicroED) is a new cryo-electron microscopy (cryo-EM) method capable of determining macromolecular structures at atomic resolution from vanishingly small 3D crystals. MicroED promises to solve atomic resolution structures from even the tiniest of crystals, less than a few hundred nanometers thick. MicroED complements frontier advances in crystallography and represents part of the rebirth of cryo-EM that is making macromolecular structure determination more accessible for all. Here we review the concept and practice of MicroED, for both the electron microscopist and crystallographer. Where other reviews have addressed specific details of the technique (Hattne et al., 2015; Shi et al., 2016; Shi, Nannenga, Iadanza, & Gonen, 2013), we aim to provide context and highlight important features that should be considered when performing a MicroED experiment.

    The program consisted of three phases: (I) characterization of the physical and chemical properties of EDS, (II) evaluation of EDS in a laboratory medium-speed diesel engine, and (III) evaluation of EDS in a low-speed diesel engine operating at a utility. The characteristics of high aromatic content and low cetane number that were found during Phase I made it unlikely that EDS could be used as a direct substitute for diesel fuel without engine modification to provide ignition assistance. Phase II was conducted on a 12-cylinder General Electric Company 7FDL diesel engine. Blends of up to 30% EDS and 70% 0.2 diesel fuel (DF-2) were successfully consumed. Dual fuel tests were also conducted on a single cylinder by injecting EDS through the existing engine fuel oil system and injecting DF-2 through an auxiliary nozzle as an ignition source. Acceptable operation was achieved using 5 to 10% pilot oil heat input. Phase III was conducted on a 16-cylinder Cooper-Bessemer LSV-16-GDT diesel engine at an EUC plant in Easton, Maryland. Blends of up to 66.7% EDS and 33.3% DF-2 were successfully consumed. Dual fuel tests were also conducted on a single cylinder by injecting EDS through the existing fuel oil system and using a natural-gas-fueled precombustion chamber as an ignition source. Acceptable operation was achieved using 3 to 6% pilot gas heat input. The program confirmed that it is feasible to consume significant proportions of EDS in a diesel engine, but more development is needed before EDS can be considered a viable alternative liquid fuel for diesel engines, and an industrial hygiene program is needed to assure safe handling of the fuel.

    Introduction The Accreditation Council for Graduate Medical Education requires that residency programs ensure resident competency in performing safe, effective handoffs. Understanding resident, attending, and nurse perceptions of the key elements of a safe and effective emergency department (ED) handoff is a crucial step to developing feasible, acceptable educational interventions to teach and assess this fundamental competency. The aim of our study was to identify the essential themes of ED-based handoffs and to explore the key cultural and interprofessional themes that may be barriers to developing and implementing successful ED-based educational handoff interventions. Methods Using a grounded theory approach and constructivist/interpretivist research paradigm, we analyzed data from three primary and one confirmatory focus groups (FGs) at an urban, academic ED. FG protocols were developed using open-ended questions that sought to understand what participants felt were the crucial elements of ED handoffs. ED residents, attendings, a physician assistant, and nurses participated in the FGs. FGs were observed, hand-transcribed, audio-recorded and subsequently transcribed. We analyzed data using an iterative process of theme and subtheme identification. Saturation was reached during the third FG, and the fourth confirmatory group reinforced the identified themes. Two team members analyzed the transcripts separately and identified the same major themes. Results ED providers identified that crucial elements of ED handoff include the following: 1) Culture (provider buy-in, openness to change, shared expectations of sign-out goals); 2) Time (brevity, interruptions, waiting); 3) Environment (physical location, ED factors); 4) Process (standardization, information order, tools). Conclusion Key participants in the ED handoff process perceive that the crucial elements of intershift handoffs involve the themes of culture, time, environment, and process. Attention to these

    Photosynthetic capacity is a key plant trait that determines the rate of photosynthesis; however, in Earth System Models it is either a fixed value or derived from a linear function of leaf nitrogen content. A mechanistic leaf nitrogen allocation model have been developed for a DOE-sponsored Community Land Model coupled to the Ecosystem Demography model (CLM-ED) to predict the photosynthetic capacity [Vc,max25 (μmol CO2 m-2 s-1)] under different environmental conditions at the global scale. We collected more than 800 data points of photosynthetic capacity (Vc,max25) for 124 species from 57 studies with the corresponding leaf nitrogen content and environmental conditions (temperature, radiation, humidity and day length) from literature and the NGEE arctic site (Barrow). Based on the data, we found that environmental control of Vc,max25 is about 4 times stronger than the leaf nitrogen content. Using the Markov-Chain Monte Carlo simulation approach, we fitted the collected data to our newly developed nitrogen allocation model, which predict the leaf nitrogen investment in different components including structure, storage, respiration, light capture, carboxylation and electron transport at different environmental conditions. Our results showed that our nitrogen allocation model explained 52% of variance in observed Vc,max25 and 65% variance in observed Jmax25 using a single set of fitted model parameters for all species. Across the growing season, we found that the modeled Vc,max25 explained 49% of the variability in measured Vc,max25. In the context of future global warming, our model predicts that a temperature increase by 5oC and the doubling of atmospheric carbon dioxide reduced the Vc,max25 by 5%, 11%, respectively.

  16. AB006. Erectile dysfunction (ED) as a marker for cardiovascular diseases (CVD)

    PubMed Central

    Torres, Luiz Otavio

    2015-01-01

    In 1973 V. Michal, a vascular surgeon said “Erectile dysfunction (ED) is related to diseases of the vascular bed”. And this makes sense since ED and cardiovascular diseases (CVD) share many risk factors like aging, obesity, inactivity, smoking, depression, dyslipidemia, hypertension, diabetes/insuline resistance. These conditions may lead to an oxidative stress which ultimately can promote vasoconstriction, thrombosis, atherosclerosis and finally ED and CVD. One of the most accepted Idea is that small vessels plug earlier, it means, small arteries when have for example 50% of obstruction will probably have a clinical manifestation before bigger arteries!

    The crash landing of an Aero Med helicopter on the roof of a Grand Rapids, MI, hospital required the ED team to spring into action. Here are some lessons you can draw from their experience: You or your staff might need to assist fire or EMS personnel in transporting victims to the ED or evacuating the hospital. Even if your ED is not overwhelmed with patients, it might be necessary to go on lockdown to keep onlookers and other unwanted visitors out. Be prepared to discharge stable patients to make room for others with more urgent needs. PMID:18770940

    This paper proposes a new magnetic levitation scheme which is able to generate levitation force for all speeds including a standstill. Auxiliary wheels which are needed in EDS MAGLEV vehicle can be eliminated. This scheme uses AC superconducting magnets to generate levitation force. In this paper, magnetic fields, forces and power dissipations generated by AC magnets moving above a conducting slab are calculated analytically. Results of calculation show characteristics of EDS system with AC magnet, such as levitation force and loss, are superior to those of EDS system with DC magnets for all speeds.

    This chart describes the Skylab student experiment ED-61, Plant Growth, and experiment ED-62, Plant Phototropism. Two similar proposals were submitted by Joel G. Wordekemper of West Point, Nebraska, and Donald W. Schlack of Downey, California. Wordekemper's experiment (ED-61) was to see how the lack of gravity would affect the growth of roots and stems of plants. Schlack's experiment (ED-62) was to study the effect of light on a seed developing in zero gravity. The growth container of the rice seeds for their experiment consisted of eight compartments arranged in two parallel rows of four. Each had two windowed surfaces to allow periodic photography of the developing seedlings. In March 1972, NASA and the National Science Teachers Association selected 25 experiment proposals for flight on Skylab. Science advisors from the Marshall Space Flight Center aided and assisted the students in developing the proposals for flight on Skylab.

    1997-05-01

    A body of data relates the ED50 for laser-induced retinal damage to exposure duration for visible-wavelength laser exposure and for 1064 nm laser exposure. The database, extending from sub-nanosecond exposures to kilosecond exposures, can for the most part, be fit to models based on thermal interactions, thermal-mechanical mechanisms, and photochemical processes. Exceptions to this fit occur between 1 and 100 microseconds where the damage mechanism transitions from exclusively thermal to thermal-mechanical. Disagreement exists as to whether this anomalous dip of ED50 is real or is an artifact of the data. We determined the laser-induced retinal ED50 in Rhesus monkey eyes for several exposure durations from 12 nanoseconds to 1000 milliseconds at 755 nm using a dye laser, an alexandrite laser, and a Ti:Sapphire laser. These data do not show a dip in ED50 in the microsecond time period.

    Ehlers-Danlos syndrome (EDS) is an inherited connective tissue disorder that can have a substantial impact on daily life. The aims of this study were to describe the symptoms reported in a group of individuals with EDS and to investigate the impact on functional health status by means of the Sickness Impact Profile (SIP). Seventy-seven individuals, members of the Swedish EDS Association, completed 2 mailed questionnaires. The most frequent symptoms were related to activity, e.g., joint problems (75%), to pain (71%), and to skin/tissue (52%). Pain was reported by 37 individuals (48%) as their most severe symptom. The SIP results showed an overall mean score of 13.0 (females 13.9, males 5.6), compared with a Swedish reference group with a SIP score 1.3. Women with EDS reported a better functional health status than females with rheumatoid arthritis (overall SIP score 13.9 versus 21.4). In comparison with women with fibromyalgia, the EDS females rated their functional health status as worse on the physical dimension (p <0.05) and the subscale home management (p <0.05), and as better on the subscale work (p <0.05). Impact of EDS on the individual's daily life needs to be acknowledged, assessed, and evaluated in healthcare. PMID:17039161

    Representative process materials were obtained from the EDS pilot plant for chemical and biological analyses. These materials were characterized for biological activity and chemical composition using a microbial mutagenicity assay and chromatographic and mass spectrometric analytical techniques. The two highest boiling distillation cuts, as well as process solvent (PS) obtained from the bottoms recycle mode operation, were tested for initiation of mouse skin tumorigenicity. All three materials were active; the crude 800/sup 0 +/F cut was substantially more potent than the crude bottoms recycle PS or 750 to 800/sup 0/F distillate cut. Results from chemical analyses showed the EDS materials, in general, to be more highly alkylated and have higher hydroaromatic content than analogous SRC II process materials (no in-line process hydrogenation) used for comparison. In the microbial mutagenicity assays the N-PAC fractions showed greater activity than did the aliphatic hydrocarbon, hydroxy-PAH, or PAH fractions, although mutagenicity was detected in certain PAH fractions by a modified version of the standard microbial mutagenicity assay. Mutagenic activities for the EDS materials were lower, overall, than those for the corresponding materials from the SRC II process. The EDS materials produced under different operational modes had distinguishable differences in both their chemical constituency and biological activity. The primary differences between the EDS materials studied here and their SRC II counterparts used for comparison are most likely attributable to the incorporation of catalytic hydrogenation in the EDS process. 27 references, 28 figures, 27 tables.

    Curved membranes are a common and important attribute in cells. Protein and peptide curvature sensors are known to activate signaling pathways, initiate vesicle budding, trigger membrane fusion, and facilitate molecular transport across cell membranes. Nonetheless, there is little understanding how these proteins and peptides achieve preferential binding of different membrane curvatures. The current study is to elucidate specific factors required for curvature sensing. As a model system, we employed a recently identified peptide curvature sensor, MARCKS-ED, derived from the effector domain of the myristoylated alanine-rich C-kinase substrate protein, for these biophysical investigations. An atomistic molecular dynamics (MD) simulation suggested an important role played by the insertion of the Phe residues within MARCKS-ED. To test these observations from our computational simulations, we performed electron paramagnetic resonance (EPR) studies to determine the insertion depth of MARCKS-ED into differently curved membrane bilayers. Next, studies with varied lipid compositions revealed their influence on curvature sensing by MARCKS-ED, suggesting contributions from membrane fluidity, rigidity, as well as various lipid structures. Finally, we demonstrated that the curvature sensing by MARCKS-ED is configuration independent. In summary, our studies have shed further light to the understanding of how MARCKS-ED differentiates between membrane curvatures, which may be generally applicable to protein curvature sensing behavior.

    The objective of this study was to estimate the clinical and economic impact of smoking among adult emergency department (ED) patients. An attributable risk analysis of patients seen in 2 urban EDs in 1998 was performed. Data were obtained from hospital databases, national sources describing the prevalence of smoking in the state, and risk ratios for smoking-related illnesses. Of 78,617 patient visits, 12,573 (16.0%) had any smoking-related International Classification of Diseases, 9th Revision code. The smoking-attributable risk fraction (SARF) for all patients was 4.9% (95% confidence interval [CI] 4.7%-5.0%). Of 13,245 admissions, 6.8% (95% CI 6.4%-7.2%) were smoking attributable. Of $296,962,685 in hospital charges, 10.0% (95% CI 9.9%-10.1%) were smoking attributable. The SARFs for ED visits, admissions, and charges for men were higher than for women (all P <.0001). Smoking-attributable illness accounts for 4.9% of ED adult visits, 6.8% of ED adult admissions, and 10.0% of hospital charges. The use of ED-based smoking intervention remains to be determined.

    Hybrid poplar plantations are an important source being evaluated for biomass production. Effective management of such plantations requires adequate growth and yield models. The Ecosystem Demography model (ED) makes predictions about the large scales of interest in above- and belowground ecosystem structure and the fluxes of carbon and water from a description of the fine-scale physiological processes. In this study, we used a workflow management tool, the Predictive Ecophysiological Carbon flux Analyzer (PECAn), to integrate literature data, field measurement and the ED model to provide predictions of ecosystem functioning. Parameters for the ED ensemble runs were sampled from the posterior distribution of ecophysiological traits of Populus species compiled from the literature using a Bayesian meta-analysis approach. Sensitivity analysis was performed to identify the parameters which contribute the most to the uncertainties of the ED model output. Model emulation techniques were used to update parameter posterior distributions using field-observed data in northern Wisconsin hybrid poplar plantations. Model results were evaluated with 5-year field-observed data in a hybrid poplar plantation at New Franklin, MO. ED was then used to predict the spatial variability of poplar yield in the coterminous United States (United States minus Alaska and Hawaii). Sensitivity analysis showed that root respiration, dark respiration, growth respiration, stomatal slope and specific leaf area contribute the most to the uncertainty, which suggests that our field measurements and data collection should focus on these parameters. The ED model successfully captured the inter-annual and spatial variability of the yield of poplar. Analyses in progress with the ED model focus on evaluating the ecosystem services of short-rotation woody plantations, such as impacts on soil carbon storage, water use, and nutrient retention.

    Objectives Collaboration between the orthopaedic and emergency medicine (ED) services has resulted in standardised treatment pathways, leaflet supported discharge and a virtual fracture clinic review. Patients with minor, stable fractures are discharged with no further follow-up arranged. We aimed to examine the time taken to assess and treat these patients in the ED along with the rate of unplanned reattendance. Design A retrospective study was undertaken that covered 1 year before the change and 1 year after. Prospectively collected administrative data from the electronic patient record system were analysed and compared before and after the change. Setting An ED and orthopaedic unit, serving a population of 300 000, in a publicly funded health system. Participants 2840 patients treated with referral to a traditional fracture clinic and 3374 patients managed according to the newly redesigned protocol. Outcome measures Time for assessment and treatment of patients with orthopaedic injuries not requiring immediate operative management, and 7-day unplanned reattendance. Results Where plaster backslabs were replaced with removable splints, the consultation time was reduced. There was no change in treatment time for other injuries treated by the new discharge protocol. There was no increase in unplanned ED attendance, related to the injury, within 7 days (p=0.149). There was a decrease in patients reattending the ED due to a missed fracture clinic appointment. Conclusions This process did not require any new time resources from the ED staff. This process brought significant benefits to the ED as treatment pathways were agreed. The pathway reduced unnecessary reattendance of patients at face-to-face fracture clinics for a review of stable, self-limiting injuries. PMID:24928593

    SR-71 research pilot Ed Schneider is pictured here in front of an SR-71 Blackbird on the ramp at the Dryden Flight Research Center, Edwards, California. Schneider became a NASA research pilot at Dryden in 1983. Data from the SR-71 program will be used to aid designers of future supersonic aircraft and propulsion systems. He retired as a NASA research pilot in September 2000. Two SR-71 aircraft have been used by NASA as testbeds for high-speed and high-altitude aeronautical research. The aircraft, an SR-71A and an SR-71B pilot trainer aircraft, have been based here at NASA's Dryden Flight Research Center, Edwards, California. They were transferred to NASA after the U.S. Air Force program was cancelled. As research platforms, the aircraft can cruise at Mach 3 for more than one hour. For thermal experiments, this can produce heat soak temperatures of over 600 degrees Fahrenheit (F). This operating environment makes these aircraft excellent platforms to carry out research and experiments in a variety of areas -- aerodynamics, propulsion, structures, thermal protection materials, high-speed and high-temperature instrumentation, atmospheric studies, and sonic boom characterization. The SR-71 was used in a program to study ways of reducing sonic booms or over pressures that are heard on the ground, much like sharp thunderclaps, when an aircraft exceeds the speed of sound. Data from this Sonic Boom Mitigation Study could eventually lead to aircraft designs that would reduce the 'peak' overpressures of sonic booms and minimize the startling affect they produce on the ground. One of the first major experiments to be flown in the NASA SR-71 program was a laser air data collection system. It used laser light instead of air pressure to produce airspeed and attitude reference data, such as angle of attack and sideslip, which are normally obtained with small tubes and vanes extending into the airstream. One of Dryden's SR-71s was used for the Linear Aerospike Rocket Engine, or

    Advances in scanning electron microscopy (SEM) enable the high-resolution imaging of single nanoparticles (NPs) with sizes well below 10 nm. The SEM analysis in transmission mode (T-SEM) of NPs on thin film supports has many benefits when compared to the analysis of NPs on bulk substrates. The enhanced material (mass - thickness) contrast of the T-SEM imaging mode is well suited for in-depth and, particularly valuable, to very accurate, traceable, lateral dimensional measurements of NPs. Compared to samples prepared on bulk substrates, T-SEM with energy dispersive X-ray spectroscopy (EDS) achieves a drastically improved spatial resolution of the emitted X-rays. The poor signal-to-noise ratio of the X-ray spectra emitted by a single nanoparticle (NP) can be improved by the use of high-sensitivity (high collection solid angle) silicon drift (SDD), energy-dispersive X-ray spectrometers (EDS). The EDS spectral imaging of a single NP with a spatial resolution below 10 nm has become possible. This is demonstrated by means of various examples of nanostructures. Advanced data processing of T-SEM/EDS results sets the stage for the automated classification of NPs by feature analysis. This method combines the detection of morphological structures of interest by image processing of T-SEM micrographs with the chemical classification by EDS.

  13. Crowded EDs leaving proven strategies for improving patient flow on the table.

    2016-02-01

    While there is a plethora of proven strategies to address crowding, some of the most crowded EDs have failed to take full advantage of these tactics, according to a new study that examined the adoption of a range of both ED-based and hospital-wide interventions at hospitals between 2007 and 2010. The investigators are calling for a national strategy to address crowding as well as the implementation of new measures. They also say that more steps need to be taken so that hospital leaders are held accountable for ED crowding. Researchers found that the average number of interventions adopted to reduce crowding increased during the study period from 5.2% to 6.6%, but that some of the most crowded facilities failed to adopt interventions that have been proven to work well. For instance, 19% of the most crowded EDs did not use bedside registration and 94% did not adopt surgical schedule smoothing, an intervention that can be adopted at little or no cost. Investigators note that the hospitals that have been successful at addressing ED crowding are those that embrace systemic solutions. PMID:26939352

    Emerging evidence suggests that mammalian hearts maintain the capacity for cardiac regeneration. Rapid and sensitive identification of cardiac cellular proliferation is prerequisite for understanding the underlying mechanisms and strategies of cardiac regeneration. The following immunologically related markers of cardiac cells were analyzed: cardiac transcription factors Nkx2.5 and Gata 4; specific marker of cardiomyocytes TnT; endothelial cell marker CD31; vascular smooth muscle marker smooth muscle myosin IgG; cardiac resident stem cells markers IsL1, Tbx18, and Wt1. Markers were co-localized in cardiac tissues of embryonic, neonatal, adult, and pathological samples by 5-ethynyl-2'-deoxyuridine (EdU) staining. EdU was also used to label isolated neonatal cardiomyocytes in vitro. EdU robustly labeled proliferating cells in vitro and in vivo, co-immunostaining with different cardiac cells markers. EdU can rapidly and sensitively label proliferating cardiac cells in developmental and pathological states. Cardiac cell proliferation assessed by EdU is a novel analytical tool for investigating the mechanism and strategies of cardiac regeneration in response to injury. PMID:25480318

    An important emerging issue is the estimation of renewables' contributions to reliably meeting system demand, or their capacity value. While the capacity value of thermal generation can be estimated easily, assessment of wind and solar requires a more nuanced approach due to resource variability. Reliability-based methods, particularly, effective load-carrying capacity (ELCC), are considered to be the most robust techniques for addressing this resource variability. The Regional Energy Deployment System (ReEDS) capacity expansion model and other long-term electricity capacity planning models require an approach to estimating CV for generalized PV and system configurations with low computational and data requirements. In this paper we validate treatment of solar photovoltaic (PV) capacity value by ReEDS capacity expansion model by comparing model results to literature for a range of energy penetration levels. Results from the ReEDS model are found to compare well with both comparisons--despite not being resolved at an hourly scale.

    2014-07-01

    Exposure to drugs and toxins is a major cause for patients' visits to the emergency department (ED). For most drugs-of-abuse intoxication, ED physicians are skeptical to rely on results of urine drug testing for emergent management decisions. This is partially because immunoassays, although rapid, have limitations in sensitivity and specificity and chromatographic assays, which are more definitive, are more labor intensive. Testing for toxic alcohols is needed, but rapid commercial assays are not available. ED physicians need stat assays for acetaminophen, salicylates, co-oximetry, cholinesterase, iron, and some therapeutic drugs that could be used as agents of self-harm. In this review, we look at the potential limitations of these screening tests and suggest improvements and innovations needed for better clinical utilization. New drugs of abuse should be sought and assays should be developed to meet changing abuse patterns. PMID:25337490

    A former patient in a Tampa, FL, ED, returned to the department in scrubs, claimed to be a temp, and was allowed to work despite not having any ID. To avoid similar problems, your ED should have a well-defined set of rules for people who report for work without an ID and/or do not demonstrate the requisite skills to treat patients. No badge, no work" is a good rule, unless the person is well known to you. All ED staff, including physicians and ancillary workers, should be prepared to produce photo ID immediately upon request. If staff cannot reach you, they should be encouraged to report interlopers to security or local police, as they are guilty of trespassing. PMID:17518140

    2015-01-01

    Suicide is the third leading cause of death in adolescents, and often youths with suicidal behavior or ideation present to the emergency department (ED) for care. Many suicidal youths do not receive mental health care after discharge from the ED, and interventions are needed to enhance linkage to outpatient intervention. This paper describes the Family Intervention for Suicide Prevention (FISP). Designed for use in emergency settings, the FISP is a family-based cognitive-behavior therapy session designed to increase motivation for follow-up treatment, support, coping, and safety, augmented by care linkage telephone contacts after discharge. In a randomized trial of the intervention, the FISP was shown to significantly increase the likelihood of youths receiving outpatient treatment, including psychotherapy and combined medication and psychotherapy. The FISP is a brief, focused, efficacious treatment that can be delivered in the ED to improve the probability of follow-up treatment for suicidal youths. PMID:25904825

    Background: In recent decades, the increasing crowdedness of the emergency departments has posed various problems for patients and healthcare systems worldwide. These problems include prolonged hospital stay, patient dissatisfaction and nurse burnout or job dissatisfaction. Objectives: The aim of this study was to investigate the effect of emergency department (ED) nurses’ job specialization on their job satisfaction and the length of patient stay in the ED. Patients and Methods: This before-after quasi-experimental study was conducted from April to May 2014 at the Baqiyatallah Hospital, Tehran, Iran. Initially, 35 patients were recruited as controls and the length of their stay in the ED was measured in minutes via a chronometer; Moreover, nurses’ job satisfaction was evaluated using the Mohrman-Cooke-Mohrman job satisfaction scale. Then, a job specialization intervention was developed based on the stabilization model. After that, 35 new patients were recruited to the treatment group and received specialized care services. Accordingly, the length of their stay in the ED was measured. Moreover, the same nurses’ job satisfaction was re-evaluated after the study. The study intervention lasted one month. Data were analyzed using the SPSS software version 20 and statistical tests such as the Kolmogrov-Smirnov, the paired and the independent t, and chi-square tests. Results: There was a significant difference between the two groups of patients concerning the length of their stay in the ED (P < 0.001). Moreover, compared with the pretest readings, nurses had greater job satisfaction after the study (P < 0.001). Conclusions: The job specialization intervention can improve nurses’ satisfaction and relieve the crowdedness of the EDs. PMID:27218054

    2015-10-01

    For forensic investigation in the food industry, scanning electron microscopy (SEM) in conjunction with energy dispersive X-ray spectrometry (EDS) is a powerful, often non-destructive, instrumental analysis tool to provide information about: • Identification of inorganic (and some organic) materials found as foreign contaminants in food products returned by consumers or detected during quality control inspections in the production facilities • Identification of wear particles found in production lines • Distribution of materials within a matrix • Corrosion and failure analysis of production equipment The identification of materials by SEM/EDS is accomplished through a combination of morphology by SEM imaging and the elemental composition of the material by EDS. Typically, the EDS analysis provides a qualitative spectrum showing the elements present in the sample. Further analysis can be done to quantify the detected elements in order to further refine the material identification. Metal alloys can often be differentiated even within the same family such as 300 Series stainless steels. Glass types can be identified by the elemental composition where the detected elements are quantified as the oxides of each element. In this way, for example, common window glass is distinguishable from insulation glass used in many ovens. Wear particles or fragments from breakage can find their way into food products. SEM/EDS analysis of the materials is an important resource to utilize when trying to determine the original source. Suspected source materials can then be sampled for comparative analysis. EDS X-ray mapping is another tool that is available to provide information about the distribution of materials within a matrix. For example, the distribution of inorganic ingredients in a dried food helps to provide information about the grind and blend of the materials.

    Introduction Diverticulitis is a common diagnosis in the emergency department (ED). Outpatient management of diverticulitis is safe in selected patients, yet the rates of admission and surgical procedures following ED visits for diverticulitis are unknown, as are the predictive patient characteristics. Our goal is to describe trends in admission and surgical procedures following ED visits for diverticulitis, and to determine which patient characteristics predict admission. Methods : We performed a cross-sectional descriptive analysis using data on ED visits from 2006–2011 to determine change in admission and surgical patterns over time. The Nationwide Emergency Department Sample database, a nationally representative administrative claims dataset, was used to analyze ED visits for diverticulitis. We included patients with a principal diagnosis of diverticulitis (ICD-9 codes 562.11, 562.13). We analyzed the rate of admission and surgery in all admitted patients and in low-risk patients, defined as age <50 with no comorbidities (Elixhauser). We used hierarchical multivariate logistic regression to identify patient characteristics associated with admission for diverticulitis. Results Fryom 2006 to 2011 ED visits for diverticulitis increased by 21.3% from 238,248 to 302,612, while the admission rate decreased from 55.7% to 48.5% (−7.2%, 95% CI [−7.78 to −6.62]; p<0.001 for trend). The admission rate among low-risk patients decreased from 35.2% in 2006 to 26.8% in 2011 (−8.4%, 95% CI [−9.6 to −7.2]; p<0.001 for trend). Admission for diverticulitis was independently associated with male gender, comorbid illnesses, higher income and commercial health insurance. The surgical rate decreased from 6.5% in 2006 to 4.7% in 2011 (−1.8%, 95% CI [−2.1 to −1.5]; p<0.001 for trend), and among low-risk patients decreased from 4.0% to 2.2% (−1.8%, 95% CI [−4.5 to −1.7]; p<0.001 for trend). Conclusion From 2006 to 2011 ED visits for diverticulitis increased

    2012-01-01

    Hospitals planning to construct new EDs have a golden opportunity to integrate designs and materials that can please both patients and providers. Experts say attention to acoustics, privacy, and air quality can lower stress levels and boost satisfaction. Further, designs that prioritize efficient work flows get high marks from providers. Experts advise hospital leaders to get considerable input from patients before designing a new ED facility. Privacy, quiet, and a connection to nature are top priorities for patients. Use design to enhance patient flow. PMID:22413731

    Several similarities exist in the phenomenology of obsessive-compulsive disorder (OCD) and eating disorders (ED : anorexia nervosa and bulimia). Both disorders include obsessive thoughts and compulsive or ritualized behaviours. Furthermore, these two disorders frequently present with similar comorbid disorders. In this article, the authors examine similarities between ED and OCD, and whether eating disorders can be conceptualized as a variant of obsessive-compulsive disorders. This raises the possibility that treatments proven effective for OCD could be successfully adapted for ED. The authors consequently further examine both treatments utilized for both disorders.

    Dengue fever is a re-emerging tropical disease and its severe form is caused by cross-reactivity between its four serotypes (DEN1, DEN2, DEN3 and DEN4). The third domain of the viral envelope protein (ED3) contains the two major putative epitopes and is a highly suitable model protein for examining the molecular determinants of a virus' sero-specificity. Here we examine d the sero-specificity and cross-reactivity of the immune response against DEN3 and DEN4 ED3 using six epitope grafted ED3 variants where the surface-exposed epitope residues from DEN3 ED3 were switched to those of DEN4 ED3 and vice versa. We prepared anti-DEN3 and anti-DEN4 ED3 serum by immunizing Swiss albino mice and measured their reactivities against all six grafted mutants. As expected, both sera exhibited strong reactivity against its own serotype's ED3, and little cross-reactivity against their counterpart serotype's ED3s. E2 played a major role in the sero-specificity of anti-DEN3 serum, whereas E1 was important for DEN4 ED3's sero-specificity. Next, the reactivity patterns corroborated our working hypothesis that sero-specificity could be transferred by grafting the surface exposed epitope residues from one serotype to the other. To analyze the above results from a structural viewpoint, we determined the crystal structure of a DEN4 ED3 variant, where E2 was grafted from DEN3 ED3, at 2.78Å resolution and modeled the structures of the five remaining grafted variants by assuming that the overall backbone remained unchanged. The examination of the electrostatic and molecular surfaces of the variants suggested some further rationale for the sero-specificity of the immune responses. PMID:26160751

    We report our effort to quantify atomic-scale chemical maps obtained by collecting energy-dispersive X-ray spectra (EDS) using scanning transmission electron microscopy (STEM) (STEM-EDS). Under a thin specimen condition and when the EDS scattering potential is localized, the X-ray counts from atomic columns can be properly counted by fitting Gaussian peaks at the atomic columns, and can then be used for site-by-site chemical quantification. The effects of specimen thickness and X-ray energy on the Gaussian peak-width are investigated by using SrTiO3 (STO) as a model specimen. The relationship between the peak-width and spatial-resolution of an EDS map is also studied. Furthermore, the method developed by this work is applied to study a Sm-doped STO thin film and antiphase boundaries present within the STO film. We find that Sm atoms occupy both Sr and Ti sites but preferably the Sr sites, and Sm atoms are relatively depleted at the antiphase boundaries likely due to the effect of strain.

    Staphylococcal leukotoxins are a family of β-barrel, bicomponent, pore-forming toxins with membrane-damaging functions. These bacterial exotoxins share sequence and structural homology and target several host-cell types. Leukotoxin ED (LukED) is one of these bicomponent pore-forming toxins that Staphylococcus aureus produces in order to suppress the ability of the host to contain the infection. The recent delineation of the important role that LukED plays in S. aureus pathogenesis and the identification of its protein receptors, combined with its presence in S. aureus methicillin-resistant epidemic strains, establish this leukocidin as a possible target for the development of novel therapeutics. Here, the crystal structures of the water-soluble LukE and LukD components of LukED have been determined. The two structures illustrate the tertiary-structural variability with respect to the other leukotoxins while retaining the conservation of the residues involved in the interaction of the protomers in the bipartite leukotoxin in the pore complex.

    The NASA Exoplanet Science Institute (NExScI) maintains a series of archival services in support of NASA’s planet finding and characterization goals. Two of the larger archival services at NExScI are the Keck Observatory Archive (KOA) and the NASA Star and Exoplanet Database (NStED). KOA, a collaboration between the W. M. Keck Observatory and NExScI, serves raw data from the High Resolution Echelle Spectrograph (HIRES) and extracted spectral browse products. As of June 2009, KOA hosts over 28 million files (4.7 TB) from over 2,000 nights. In Spring 2010, it will begin to serve data from the Near-Infrared Echelle Spectrograph (NIRSPEC). NStED is a general purpose archive with the aim of providing support for NASA’s planet finding and characterization goals, and stellar astrophysics. There are two principal components of NStED: a database of (currently) all known exoplanets, and images; and an archive dedicated to high precision photometric surveys for transiting exoplanets. NStED is the US portal to the CNES mission CoRoT, the first space mission dedicated to the discovery and characterization of exoplanets. These archives share a common software and hardware architecture with the NASA/IPAC Infrared Science Archive (IRSA). The software architecture consists of standalone utilities that perform generic query and retrieval functions. They are called through program interfaces and plugged together to form applications through a simple executive library.

  16. Telepsychiatry program eases patient crowding in the ED, expedites mental health services to patients and providers.

    PubMed

    2013-11-01

    With funding from the Duke Endowment, the Albemarle Hospital Foundation in Elizabeth City, NC, implemented a telepsychiatry program aimed at decreasing patient backlogs in the health system's EDs, while also quickly connecting patients with needed mental health care. The approach has more than halved LOS for patients who are discharged to inpatient treatment facilities. The approach is also credited with reducing recidivism rates and the need for involuntary commitments. Now the state has announced plans to employ a similar approach statewide. Patients in the ED are connected with psychiatric providers at a remote location through the use of telemedicine carts that are equipped with wireless technology. With expedited psychiatric treatment, administrators say that nearly 30% of patients with involuntary commitment (IVC) orders stabilize to the point that their IVC orders can be rescinded and they can be discharged from the ED to outpatient care. Since the start of the pilot program in March of 2011, project administrators report that the average LOS in the ED for patients discharged to inpatient treatment facilities has decreased from 48 hours to 22.5 hours.

    2014-10-13

    We report our effort to quantify atomic-scale chemical maps obtained by collecting energy-dispersive X-ray spectra (EDS) using scanning transmission electron microscopy (STEM) (STEM-EDS). Under a thin specimen condition and when the EDS scattering potential is localized, the X-ray counts from atomic columns can be properly counted by fitting Gaussian peaks at the atomic columns, and can then be used for site-by-site chemical quantification. The effects of specimen thickness and X-ray energy on the Gaussian peak-width are investigated by using SrTiO3 (STO) as a model specimen. The relationship between the peak-width and spatial-resolution of an EDS map is also studied. Furthermore,more » the method developed by this work is applied to study a Sm-doped STO thin film and antiphase boundaries present within the STO film. We find that Sm atoms occupy both Sr and Ti sites but preferably the Sr sites, and Sm atoms are relatively depleted at the antiphase boundaries likely due to the effect of strain.« less

    Introduction Assessment reactivity may be a factor in the modest results of brief interventions for substance use in the emergency department (ED). The presence of assessment reactivity in studies of interventions for intimate partner violence (IPV) has not been studied. Our objectives were to identify ED IPV intervention studies and evaluate the presence of a consistently positive effect on the control groups. Methods We performed a systematic search of electronic databases for English=language intervention studies addressing IPV in the ED published since 1990. Study selection and assessment of methodologic quality were performed by two independent reviewers. Data extraction was performed by one reviewer and then independently checked for completeness and accuracy by a second reviewer. Results Of 3,620 unique manuscripts identified by database search, 667 underwent abstract review and 12 underwent full-text review. Only three met full eligibility criteria; data on the control arm were available for two studies. In these two studies, IPV-related outcomes improved for both the experimental and control condition. Conclusion The paucity of controlled trials of IPV precluded a robust evaluation for assessment reactivity. This study highlighted a critical gap in ED research on IPV. PMID:26759650

    2001-05-01

    High-energy use of 1318 nm laser systems is becoming more prevalent in military and industrial settings. Threshold, ED50, exposure data and mechanism of laser-tissue interaction need to be determined for this wavelength using appropriate animal models that allow for extrapolation to control human exposures. Threshold, ED50, exposure data at 1318 nm for retinal and corneal injury have previously been undertaken and reported for rhesus monkeys. Using comparable methods, we examine exposure data at 1318 nm to determine the ED50 and laser-tissue interaction in the rabbit model to evaluate cornea. We present preliminary data for the ED50 threshold on the cornea from exposure to 1318 nm single laser pulses. Delivery of laser energy is accomplished using an Nd:YAG system producing 1318 nm light in the 0.5 millisecond time exposure regime and in the range of 0 to 500 mJ. Results from this work will aid in the establishment of safety standards for near infrared laser systems.

  20. Relationship between the two surgical access of aortoiliac occlusive disease and recovery of ED.

    PubMed

    Verim, L; Kalko, Y

    2015-01-01

    Aortoiliac occlusive disease (AIOD) can occur anywhere from the distal abdominal aorta to the common femoral arteries. Patients with AIOD may be asymptomatic or may have intermittent claudication or critical limb ischemia. ED in the young males may be the first symptom of aortoiliac disease. The aims of this study were to determine the outcome of ED in patients who underwent aortoiliac surgery and evaluate the effect of revascularization upon erectile function (EF) by using the international index of EF questionnaire and color duplex Doppler ultrasonography. A total of 60 patients under 65-year-old age eligible for elective repair of AIOD s were included in this study. The patients were randomly divided into two equal groups. The first group (group A) patients were operated by minimally invasive retroperitoneal approach (RPA) and the second group (group B) patients were operated by transperitoneal approach (TPA) to the aorta. The quality of sexual function scale was evaluated preoperatively and at 6 months postoperatively. Surgical revascularization when appropriate, symptomatic AIOD and ED are often improved. As a result of our study, RPA to the aorta is superior to TPA because of recovering with the higher systolic velocity values of penile Doppler in ED cases. PMID:25099637

  3. Broad Categories for the Diagnosis of Eating Disorders (BCD-ED): An Alternative System for Classification

    PubMed Central

    Walsh, B. Timothy; Sysko, Robyn

    2009-01-01

    Eating Disorder Not Otherwise Specified (EDNOS), a residual category in DSM-IV, is the most commonly used eating disorder diagnosis in clinical settings. However, the features of individuals with EDNOS are heterogeneous and difficult to characterize. A diagnostic scheme, termed Broad Categories for the Diagnosis of Eating Disorders (BCD-ED), is proposed to diminish use of the EDNOS category markedly while preserving the existing eating disorder categories. The BCD-ED scheme consists of three broad categories, in a hierarchical relationship, consisting of: Anorexia Nervosa and Behaviorally Similar disorders, Bulimia Nervosa and Behaviorally Similar Disorders, Binge Eating Disorder and Behaviorally Similar Disorders, and a residual category of EDNOS. The advantages and disadvantages of adopting this scheme for DSM-V are considered, and issues relevant to BCD-ED are discussed. Specifically, we review the proportion of individuals with DSM-IV EDNOS that would be re-classified under the BCD-ED system, support for the hierarchy of the three categories, and the potential risk of “overdiagnosis.” PMID:19650083

  6. EDS coal liquefaction process development: Phase V. Final technical progress report, Volume I

    SciTech Connect

    1984-02-01

    All objectives in the EDS Cooperative Agreement for Phases III-B through V have been achieved for the RCLU pilot plants. EDS operations have been successfully demonstrated in both the once-through and bottoms recycle modes for coals of rank ranging from bituminous to lignitic. An extensive data base detailing the effects of process variable changes on yields, conversions and product qualities for each coal has been established. Continuous bottoms recycle operations demonstrated increased overall conversion and improved product slate flexibility over once-through operations. The hydrodynamics of the liquefaction reactor in RCLU were characterized through tests using radioactive tracers in the gas and slurry phases. RCLU was shown to have longer liquid residence times than ECLP. Support work during ECLP operations contributed to resolving differences between ECLP conversions and product yields and those of the small pilot plants. Solvent hydrogenation studies during Phases IIIB-V of the EDS program focused on long term activity maintenance of the Ni-MO-10 catalyst. Process variable studies for solvents from various coals (bituminous, subbituminous, and lignitic), catalyst screening evaluations, and support of ECLP solvent hydrogenation operations. Product quality studies indicate that highly cyclic EDS naphthas represent unique and outstanding catalytic reforming feedstocks. High volumes of high octane motor gasoline blendstock are produced while liberating a considerable quantity of high purity hydrogen.

    IMPORTANCE Medical treatment settings such as Emergency Departments (EDs) present important opportunities to address problematic substance use. Currently, EDs do not typically intervene beyond acute medical stabilization. OBJECTIVE To contrast the effects of a brief intervention with telephone boosters (BI-B) to those of screening, assessment, and referral to treatment (SAR) and minimal screening only (MSO) among drug-using ED patients. DESIGN Between October 2010 and February 2012, 1285 patients were randomized to MSO (n = 431), SAR (n = 427), or BI-B (n = 427). Follow-up assessments were conducted at 3, 6, and 12 months by blinded interviewers. SETTING EDs of six academic hospitals in the U.S. PARTICIPANTS Participants were adult ED patients scoring ≥ 3 on the 10-item Drug Abuse Screening Test (indicating moderate to severe problems related to drug use) and currently using drugs. INTERVENTIONS Following screening, MSO participants received only an informational pamphlet. SAR participants received assessment plus referral to addiction treatment if indicated. BI-B participants received assessment and referral as in SAR, plus a manual-guided counseling session based on motivational interviewing principles and up to 2 “booster” sessions by telephone during the month following the ED visit. MAIN OUTCOMES AND MEASURES Outcomes evaluated at follow-up visits included self-reported days using the patient-defined primary problem drug, days using any drug, days of heavy drinking, and drug use based on analysis of hair samples. RESULTS Follow-up rates were 88%, 86%, and 81% at 3, 6, and 12 months, respectively. There were no significant differences between groups in self-reported days using the primary drug, days using any drug, or heavy drinking days at 3, 6, or 12 months. At the 3-month follow-up, participants in the SAR group had a higher rate of hair samples positive for their primary drug of abuse (265/280, 95%) than did participants in the MSO group (253/287, 88

    The TechEdSat spacecraft mission saw one of the fastest turn around times for concept through launch of a CubeSat. On 26 October 2011, John Hines sketched on a brown paper napkin the outline for which components would be in this 1U CubeSat, and how they would be stacked; 269 days later that spacecraft launched from Tanegashima Space Center aboard the HTV-3 ISS resupply mission, with a total development time of only eight months. TechEdSat was among the first of five CubeSats deployed from the ISS. The goals of the TechEdSat mission were to explore the use of the Space Plug-n-Play Architecture (SPA) in a CubeSat, and to evaluate Commercial Off The Shelf (COTS) space-to-space communication solutions. TechEdSat featured an array of processors from ÅAC Microtec including four NanoRTU's and the RTULite main processor, all communicating using the SPA-1 protocol. TechEdSat featured two primary payloads: an Iridium 9602 Modem, and a Quake Global Q1000 OrbComm modem. After a successful deployment on 4 October 2012 from the ISS, over 2000 packets of 122 bytes each (250 kB total) were received in the first four months of the mission. In this paper we discuss the challenges to rapid CubeSat development, the experience of having a CubeSat approved for deployment from the ISS, the ongoing results of the mission and lessons learned.
