    Broad Absorption Lines (BALs) are present in the spectra of ~20% of quasars (QSOs), indicating the presence of fast outflows (up to 0.2c) intercepting the observer's line of sight. Radio-Loud (RL) BAL QSOs are even more rare, being four times less common than Radio-Quiet (RQ) BAL QSOs. The reason for that is still not clear, leaving open questions about the nature of the BAL-producing outflows and their connection with the radio jet. We explored the spectroscopic characteristics of RL and RQ BAL QSOs, aiming at finding a possible explanation for the rarity of the former. We identified two samples of genuine BAL QSOs from SDSS optical spectra, one RL and one RQ, in a suitable redshift interval (2.5< z <3.5) that allowed us to observe the Mg II and H$\\beta$ emission lines in the adjacent Near-Infrared (NIR) band. We collected NIR spectra of the two samples using the Telescopio Nazionale Galileo (TNG, Canary Islands). Using relations known in the literature, we could estimate black hole mass, broad line re...

  5. BAL QSOs and Extreme UFOs: The Eddington Connection

    Science.gov (United States)

    Zubovas, Kastytis; King, Andrew

    2013-05-01

    We suggest a common physical origin connecting the fast, highly ionized winds (UFOs) seen in nearby active galactic nuclei (AGNs), and the slower and less ionized winds of broad absorption line (BAL) QSOs. The primary difference is the mass-loss rate in the wind, which is ultimately determined by the rate at which mass is fed toward the central supermassive black hole (SMBH) on large scales. This is below the Eddington accretion rate in most UFOs, and slightly super-Eddington in extreme UFOs such as PG1211+143, but ranges up to ~10-50 times this in BAL QSOs. For UFOs this implies black hole accretion rates and wind mass-loss rates which are at most comparable to Eddington, giving fast, highly ionized winds. In contrast, BAL QSO black holes have mildly super-Eddington accretion rates, and drive winds whose mass-loss rates are significantly super-Eddington, and so are slower and less ionized. This picture correctly predicts the velocities and ionization states of the observed winds, including the recently discovered one in SDSS J1106+1939. We suggest that luminous AGNs may evolve through a sequence from BAL QSO through LoBAL to UFO-producing Seyfert or quasar as their Eddington factors drop during the decay of a bright accretion event. LoBALs correspond to a short-lived stage in which the AGN radiation pressure largely evacuates the ionization cone, but before the large-scale accretion rate has dropped to the Eddington value. We show that sub-Eddington wind rates would produce an M-σ relation lying above that observed. We conclude that significant SMBH mass growth must occur in super-Eddington phases, either as BAL QSOs, extreme UFOs, or obscured from direct observation.

    2014-01-01

    Broad absorption line (BAL) quasars have been studied for over thirty years. Yet it is still unclear why and when we observe broad absorption lines in quasars. Is this phenomenon caused by geometry or is it connected with the evolution process? Variability of the BAL quasars, if present, can give us information about their orientation, namely it can indicate whether they are oriented more pole-on. Using the Torun 32-metre dish equipped with the One Centimetre Receiver Array (OCRA) we have started a monitoring campaign of a sample of compact radio-loud BAL quasars. This 30 GHz variability monitoring program supplements the high-resolution interferometric observations of these objects we have carried out with the EVN and VLBA.

    @@ While observing a sample of quasars with broad absorption line (BAL) in their spectra, Prof. WANG Junxian and his colleagues Prof. WANG Tinggui and Dr. ZHOU Hongyan with the Center for Astrophysics at the University of Science and Technology of China (USTC) discovered that unlike most of BAL quasars, two of the observed do not show intrinsic X-ray absorption, indicating a different composition of matter in their outflows. This might help us better understand how black holes devour and project gases, according to the astronomers.

    In this work, wurtzite BAlN layers with boron composition as high as 12% were successfully grown by MOVPE. The growth was performed at 650 C and then annealed at 1020 C. Low temperature growth was used in order to alleviate B-rich phase poisoning under high TEB/III ratio. The growth was performed by continuous epitaxy as well as by flow-modulate epitaxy. BAlN single layers with clearly defined X-ray diffraction peaks were achieved on AlN templates which are appropriate substrates for deep UV devices, as well as on GaN templates to facilitate distinguishing of the XRD peak of BAlN from the substrate peak. The layer demonstrated columnar crystalline features and inherited wurtzite structure from substrates.

    2016-01-01

    While narrow absorption lines (NALs) are relatively stable, broad absorption lines (BALs) and mini-BAL systems usually show violent time variability within a few years via a mechanism that is not yet understood. In this study, we examine variable ionization state (VIS) scenario as a plausible mechanism, as previously suspected. Over three years, we performed photometric monitoring observations of four mini-BAL and five NAL quasars at $z_{\\rm em}$ $\\sim$ 2.0 - 3.1 using the 105 cm Kiso Schmidt Telescope in $u$, $g$, and $i$-bands. We also performed spectroscopic monitoring observation of one of our mini-BAL quasar (HS1603+3820) using the 188-cm Okayama Telescope over the same period as the photometric observations. Our main results are as follows: (1) Structure function (SF) analysis revealed that the quasar UV flux variability over three years was not large enough to support the VIS scenario, unless the ionization condition of outflow gas is very low. (2) There was no crucial difference between the SFs of min...

    2015-01-01

    FeLoBALs are a rare class of quasar outflows with low-ionization broad absorption lines (BALs), large column densities, and potentially large kinetic energies that might be important for `feedback' to galaxy evolution. In order to probe the physical properties of these outflows, we conducted a multiple-epoch, absorption line variability study of 12 FeLoBAL quasars spanning a redshift range between 0.7 and 1.9 over rest frame time-scales of approximately 10 d to 7.6 yr. We detect absorption line variability with greater than 8 sigma confidence in 3 out of the 12 sources in our sample over time-scales of 0.6 to 7.6 yr. Variable wavelength intervals are associated with ground and excited state Fe II multiplets, the Mg II 2796, 2803 doublet, Mg I 2852, and excited state Ni II multiplets. The observed variability along with evidence of saturation in the absorption lines favors transverse motions of gas across the line of sight (LOS) as the preferred scenario, and allows us to constrain the outflow distance from th...

  17. A SCUBA-2 survey of FeLoBAL QSOs: Are FeLoBALs in a `transition phase' between ULIRGs and QSOs?

    It is thought that a class of broad absorption line (BAL) QSOs, characterised by Fe absorption features in their UV spectra (called `FeLoBALs'), could mark a transition stage between the end of an obscured starburst event and a youthful QSO beginning to shed its dust cocoon, where Fe has been injected into the interstellar medium by the starburst. To test this hypothesis we have undertaken deep SCUBA-2 850 $\\mu$m observations of a sample of 17 FeLoBAL QSOs with 0.89 $\\leq$ z $\\leq$ 2.78 and -23.31 $\\leq$ M$_{B}$ $\\leq$-28.50 to directly detect an excess in the thermal emission of the dust which would probe enhanced star-formation activity. We find that FeLoBALs are not luminous sources in the submillimetre, none of them are individually detected at 850 $\\mu$m, nor as a population through stacking ($F_{s}=1.14\\pm0.58$ mJy). Statistical and survival analyses reveal that FeLoBALs have sub-mm properties consistent with BAL and non-BAL QSOs with matched redshifts and magnitudes. An SED fitting analysis shows that ...

  18. Broadband nuclear emission in two radio-loud BAL quasars

    Kunert-Bajraszewska, M; Janiuk, A

    2014-01-01

    The X-ray weakness of broad absorption line (BAL) quasars in comparison to non-BAL objects is possibly caused by the absorption of X-ray emission by the shielding material near the equatorial plane. On the other hand, the radio-loud BALQSOs are more X-ray loud than the radio-quiet ones. This suggests that part of the X-ray emission may arise from the radio jet. To investigate this possibility, we modelled the nuclear spectra of two radio-loud BALQSOs. We focus on the emission from the very centres of these two objects. The source of emission was approximated by a single, homogeneous component that produces synchrotron and inverse-Compton (IC) radiation. The simplicity of the model allowed us to estimate the basic physical parameters of the emitting regions, using a universal analytic approach. Such methods have already been used in blazars. For the first time we propose this solution for quasars. In addition, we modelled the radiation spectra of the accretion disk and its corona to compare them with the jets'...

    2015-01-01

    Broad absorption lines seen in some quasars prove the existence of ionized plasma outflows from the accretion disk. Outflows together with powerful jets are important feedback processes. Understanding physics behind BAL outflows might be a key to comprehend Galaxy Evolution as a whole. First radio-loud BAL quasar was discovered in 1997 and this discovery has opened new possibilities for studies of the BAL phenomena, this time on the basis of radio emission. However, information about the radio structures, orientation and age of BAL quasars is still very limited due to weak radio emission and small sizes of these objects. Our high-resolution radio survey of a sample of BAL quasars aims to increase our knowledge about these objects. In this article, we present some conclusions arising from our research.

    2006-01-01

    Multi-frequency 1.7, 5 and 8.4-GHz VLBA observations of a radio-loud broad absorption line (BAL) quasar 1045+352 are presented. It is a young compact steep spectrum (CSS) object and its asymmetric, two-sided morphology on a scale of several hundred parsecs, extending in two different directions, may suggest intermittent activity. The young age and unusual morphology of 1045+352 are arguments in favour of an evolution scenario for BAL quasars, in which the BAL features appear at a very early stage of their evolution.

    Full Text Available It has become gradually more complex to give more attention to the importance of business value of information system in the early hours of time. Above the past few days researchers have high lightened the requirement of information system in business field. Almost every organization and industry like electronics, textile, computer, health, education etc is investing appreciably in information system. It is generally observed that IS savings facilitate firms to achieve competitive benefit and enhance central part competencies to improve their performance and increase further wages. As a result Executive Enhance Business Value of BAL Information System (EEBVBIS is at the heart of our deliberation in this research paper. This paper seeks to address the following questions. What is the role of business value in information system? How can we analyze business value of information system (IS? What is the consequence of information system in new e-commerce era? It has been generally observed that with the passage of time as the quick changes are taking place in information system the above questions are gaining importance in the field of business. The deliberation in proper selection of technology and its proper utilization to improve the performance of a business in Hospital System provide help to achieve the business value. We also covered some aspects of Hospital System using statistical study. We focus the Information System which plays an important role in Hospital System (Private and Public Hospital System.

    The synthesis of dilute B content BAlN and BGaN has been performed by an advanced MBE technique called ENABLE. ENABLE is a direct chemical activation approach to film growth which uses an energetic beam of neutral N atoms to activate nitride thin film growth. Using the ENABLE-MBE technology, up to 3.1% and 3.5% B has been incorporated in BAlN and BGaN, respectively. XRD scans indicate that the films are single phase and the crystalline quality is high. It has been shown in BAlN that a lower substrate temperature during growth leads to higher level of incorporation of B, with all other parameters held constant. Electrical measurements of BAlN shows reasonable breakdown voltage (∝25 V/μm) and leakage current (-9 nA at -20 V bias). (copyright 2014 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim) (orig.)

  4. FeLoBAL Outflow Variability Constraints from Multi-Year Observations

    2013-01-01

    The physical properties and dynamical behavior of Broad Absorption Line (BAL) outflows are crucial themes in understanding the connections between galactic centers and their hosts. FeLoBALs (identified with the presence of low-ionization Fe II BALs) are a peculiar class of quasar outflows that constitute approximately 1% of the BAL population. With their large column densities and apparent outflow kinetic luminosities, FeLoBALs appear to be exceptionally powerful and are strong candidates for feedback in galaxy evolution. We conducted variability studies of 12 FeLoBAL quasars with emission redshifts between 0.69 and 1.93, spanning both weekly and multi-year timescales in the quasar's rest frame. We detected absorption-line variability from low-ionization species (Fe II, Mg II) in four of our objects, with which we established a representative upper limit for the distance of the absorber from the supermassive black hole (SMBH) to be approximately 20 parsecs. Our goals are to understand the mechanisms producing...

    2014-01-01

    Studies of radio-loud (RL) broad absorption line (BAL) quasars indicate that popular orientation-based BAL models fail to account for all observations. Are these results extendable to radio-quiet (RQ) BAL quasars? Comparisons of RL and RQ BAL quasars show that many of their properties are quite similar. Here we extend these analyses to the rest-frame ultraviolet (UV) spectral properties, using a sample of 73 RL and 473 RQ BAL quasars selected from the Sloan Digital Sky Survey (SDSS). Each RQ quasar is individually matched to a RL quasar in both redshift (over the range $1.5 < z < 3.5$) and continuum luminosity. We compare several continuum, emission line, and absorption line properties, as well as physical properties derived from these measurements. Most properties in the samples are statistically identical, though we find slight differences in the velocity structure of the BALs that cause apparent differences in CIV emission line properties. Differences in the velocities may indicate an interaction bet...

  6. HST images of FeLoBAL quasars: Testing quasar-galaxy evolution models

    2016-01-01

    We present preliminary results from an HST imaging study of FeLoBAL quasars, which have extremely low-ionization Broad Absorption Line (BAL) outflows and might be a young quasar population based on their red colors, large far-IR luminosities (suggesting high star formation rates), and powerful outflows. Some models of quasar - host galaxy evolution propose a triggering event, such as a merger, to fuel both a burst of star formation and the quasar/AGN activity. These models suggest young quasars are initially obscured inside the dusty starburst until a "blowout" phase, driven by the starburst or quasar outflows like FeLoBALs, ends the star formation and reveals the visibly luminous quasar. Despite the popularity of this evolution scheme, there is little observational evidence to support the role of mergers in triggering AGN or the youth of dust-reddened quasars (such as FeLoBALs) compared to normal blue quasars.Our Cycle 22 HST program is designed to test the youth of FeLoBAL quasars and the connection of FeLoBALs to mergers. We obtain WFC3/IR F160W images of 10 FeLoBAL quasars at redshift z~0.9 (covering ~8500A in the quasar rest frame). We will compare the host galaxy morphologies and merger signatures of FeLoBALs with normal blue quasars (which are older according to the evolution model) and non-AGN galaxies matched in redshift and stellar mass. If FeLoBAL quasars are indeed in a young evolutionary state, close in time to the initial merging event, they should have stronger merger features compared to blue quasars and non-AGN galaxies. Preliminary results suggest that this is not the case - FeLoBAL quasars appear to reside in faint, compact hosts with weak or absent merger signatures. We discuss the implications of these results for galaxy evolution models and other studies of dust-reddened quasar populations.

    We conduct a spectroscopic search of quasars observed by the Sloan Digital Sky Survey (SDSS) with broad absorption line (BAL) troughs due to Mg II and troughs due to Fe II that simultaneously exhibit strong Balmer narrow emission lines (NELs). We find that in a redshift range of 0.4 less than or equal to z less than or equal to 0.9 approximately 23 of the 70 Mg II BALs and 4 of a subset of 15 Fe II BALs exhibit strong Balmer emission. We also find significant fractions of Mg II BALs (approximately 23%) and those Mg II BALs with Fe II troughs (approximately 27%) have strong continuum reddening, E(B - V) greater than or equal to 0.1. From measurements of the Balmer decrement in three objects, we find similarly significant reddening of the NEL region in three of the four objects; the NELs in the fourth object are not measurable. We also include one object in this study not taken from the SDSS sample that shows Fe II absorption and strong narrow emission, but due to measurement uncertainty and low continuum redde...

The effects of TMC on microstructure and tensile fracture behavior of B/Al composite were studied using transmission electron microscope(TEM) and scanning electron microscope(SEM). The fibers/matrix interfaces are degraded during TMC, the extent of which is enhanced with in creasing the cycles, causing a measurable decrease of stage Ⅰ modulus of the B/Al composite. The TMC induces the dislocation generation in the aluminum matrix and the dislocation density increases with the cycles. The synergistic effect of the matrix strengthening and the interfacial degradation during TMC is found to play an important role in controlling the changes of tensile strengths and fracture behavior of the composite. The ultimate tensile strength of the composite increases with the cycles increasing. The interfaces in the B/Al composite change from the strongly bonded states toward the appropriately-bonded ones with increasing the cycles. TMC will provide an approach of im proving the strength of B/Al composites.

  12. BAL31-NGS approach for identification of telomeres de novo in large genomes.

    Peška, Vratislav; Sitová, Zdeňka; Fajkus, Petr; Fajkus, Jiří

    2017-02-01

    This article describes a novel method to identify as yet undiscovered telomere sequences, which combines next generation sequencing (NGS) with BAL31 digestion of high molecular weight DNA. The method was applied to two groups of plants: i) dicots, genus Cestrum, and ii) monocots, Allium species (e.g. A. ursinum and A. cepa). Both groups consist of species with large genomes (tens of Gb) and a low number of chromosomes (2n=14-16), full of repeat elements. Both genera lack typical telomeric repeats and multiple studies have attempted to characterize alternative telomeric sequences. However, despite interesting hypotheses and suggestions of alternative candidate telomeres (retrotransposons, rDNA, satellite repeats) these studies have not resolved the question. In a novel approach based on the two most general features of eukaryotic telomeres, their repetitive character and sensitivity to BAL31 nuclease digestion, we have taken advantage of the capacity and current affordability of NGS in combination with the robustness of classical BAL31 nuclease digestion of chromosomal termini. While representative samples of most repeat elements were ensured by low-coverage (less than 5%) genomic shot-gun NGS, candidate telomeres were identified as under-represented sequences in BAL31-treated samples.

    Bronchoalveolar lavage (BAL) and {sup 18}F-fluorodeoxyglucose ({sup 18}F-FDG) PET can both demonstrate sarcoid activity. To assess whether metabolic activity imaged by {sup 18}F-FDG PET represents signs of disease activity as reflected by BAL, {sup 18}F-FDG PET patterns were compared with BAL cell profiles. In this retrospective analysis, 77 newly diagnosed pulmonary sarcoidosis patients underwent BAL and {sup 18}F-FDG PET. Based on {sup 18}F-FDG PET, patients were diagnosed with exclusively mediastinal/hilar activity (group A) and activity in the lung parenchyma (group B). Per group, BAL lymphocytes (%), CD4/CD8 ratio, CD103{sup +}CD4{sup +}/CD4{sup +} ratio and neutrophils (%) were compared with the extent of metabolic activity expressed as the maximum standardized uptake value (SUV{sub max}). Additionally, SUV{sub max} and BAL parameters per radiographic stage were analysed. Overall, the SUV{sub max} in the lung parenchyma correlated with neutrophils and SUV{sub max} of the mediastinum/hila correlated with the CD4/CD8 ratio. In both groups, a significant, negative correlation between the SUV{sub max} of the mediastinum/hila and the CD103{sup +}CD4{sup +}/CD4{sup +} ratio was found. In group B, the SUV{sub max} of the mediastinum/hila correlated with the CD4/CD8 ratio, while the SUV{sub max} in the lung parenchyma correlated with the CD103{sup +}CD4{sup +}/CD4{sup +} ratio and neutrophils. Significant differences were found in the SUV{sub max}, CD4/CD8 ratio, CD103{sup +}CD4{sup +}/CD4{sup +} ratio and neutrophils between the radiographic stages. The SUV{sub max} of the lung parenchyma was positively related to the radiographic stage, while the SUV{sub max} of the mediastinum/hila and CD4/CD8 ratio were inversely related. {sup 18}F-FDG PET correlates with the CD4/CD8 ratio and neutrophils, suggesting that {sup 18}F-FDG PET represents this specific cell profile in BAL. High SUV{sub max} values of the lung parenchyma may therefore correlate with more severe

    Li, Xiaohang

    2017-01-11

    Growing thicker BAlN films while maintaining single-phase wurtzite structure and boron content over 10% has been challenging. In this study, we report on the growth of 100 nm-thick single-phase wurtzite BAlN films with boron contents up to 14.4% by MOCVD. Flow-modulated epitaxy was employed to increase diffusion length of group-III atoms and reduce parasitic reactions between the metalorganics and NH3. A large growth efficiency of ∼2000 μm mol−1 was achieved as a result. Small B/III ratios up to 17% in conjunction with high temperatures up to 1010 °C were utilized to prevent formation of the cubic phase and maintain wurtzite structure.

  19. BAL: A library for the brute-force analysis of dynamical systems

    Science.gov (United States)

    Linaro, Daniele; Storace, Marco

    2016-04-01

    This paper describes the functionality and usage of BAL, a C/C++ library with a Python front-end for the brute-force analysis of continuous-time dynamical systems described by ordinary differential equations (ODEs). BAL provides an easy-to-use wrapper for the efficient numerical integration of ODEs and, by detecting intersections of the trajectory with appropriate Poincaré sections, allows to classify the asymptotic trajectory of a dynamical system for bifurcation analysis. Some examples of application are discussed, concerning two-dimensional bifurcation diagrams, Lyapunov exponents and finite-time Lyapunov exponents, basins of attraction, simulation of switching ODE systems, and integration with AUTO, a software package for continuation analysis.

  20. XMM-Newton Observation of Fe K(alpha) Emission from a BAL QSO: Mrk 231

    Turner, T. J.; Kraemer, S. B.

    2003-01-01

    We present results from a 20 ksec XMM-Newton observation of Mrk 231. EPIC spectral data reveal strong line emission due to Fe K alpha, which has rarely been detected in this class, as BAL QSOs are very faint in the X-ray band. The line energy is consistent with an origin in neutral Fe. The width of the line is equivalent to a velocity dispersion approximately 18,000 kilometers per second and thus the line may be attributed to transmission and/or reflection from a distribution of emitting clouds. If, instead, the line originates in the accretion disk then the line strength and flat X-ray continuum support some contribution from a reflected component, although the data disfavor a model where the hard X-ray band is purely reflected X-rays. The line parameters are similar to those obtained for the Fe Ka line detected in another BAL QSO, H1413 + 117.

    The B-Al permeation layers of Steel 45 were studied by means of SEM, TEM and XRD. The formation and growth model of permeation layer was proposed. The layer formation, growth and the migration behaviors of B were discussed. It is suggested that the diffusion of Al is deferred when the surface was covered by borides and aluminize compounds are surrounded by borides with the further growing of borides.

  2. A Physical Model of FeLoBALs: Implications for Quasar Feedback

    CERN Document Server

    Faucher-Giguere, C -A; Murray, N

    2011-01-01

    Photoionization modeling of the low-ionization broad absorption lines of certain quasars, known as FeLoBALs, has recently revealed the number density of the wind absorbers and their distance from the central supermassive black hole. From these, the feedback efficiency of the quasars can in principle be derived. The implied properties of the FeLoBALs are, however, surprising, with the thickness of the absorbers relative to their distance from the black hole, Delta R/R, as small as ~10^-5. Such absorbers are unlikely to survive the journey from the supermassive black hole to their inferred location. We show that the observed FeLoBAL properties are readily explained if they are formed in situ in radiative shocks produced when a quasar blast wave impacts a moderately dense interstellar clump along the line of sight. This physical picture differs significantly from the thin shell approximation often assumed, and implies outflow rates, kinetic luminosities and momentum fluxes that differ correspondingly, in some ca...

  3. Discovery of a z=0.65 Post-Starburst BAL Quasar in the DES Supernova Fields

    Energy Technology Data Exchange (ETDEWEB)

    Mudd, Dale; et al.

    2016-06-08

    We present the discovery of a z=0.65 low-ionization broad absorption line (LoBAL) quasar in a post-starburst galaxy in data from the Dark Energy Survey (DES) and spectroscopy from the Australian Dark Energy Survey (OzDES). LoBAL quasars are a minority of all BALs, and rarer still is that this object also exhibits broad FeII (an FeLoBAL) and Balmer absorption. This is the first BAL quasar that has signatures of recently truncated star formation, which we estimate ended about 40 Myr ago. The characteristic signatures of an FeLoBAL require high column densities, which could be explained by the emergence of a young quasar from an early, dust-enshrouded phase, or by clouds compressed by a blast wave. The age of the starburst component is comparable to estimates of the lifetime of quasars, so if we assume the quasar activity is related to the truncation of the star formation, this object is better explained by the blast wave scenario.

    Context. X-ray studies of AGN with powerful nuclear winds are important to constrain the physics of the inner accretion/ejection flow around SMBH, and to understand the impact of such winds on the AGN environment. Aims. Our main scientific goal is to constrain the properties of a variable outflowing absorber that is thought to be launched near the SMBH of the mini-BAL QSO PG 1126-041 using a multi-epoch observational campaign performed with XMM-Newton. Methods. We performed temporally resolved X-ray spectroscopy and simultaneous UV and X-ray photometry on the most complete set of observations and on the deepest X-ray exposure of a mini-BAL QSO to date. Results. We found complex X-ray spectral variability on time scales of both months and hours, best reproduced by means of variable massive ionized absorbers along the line of sight. As a consequence, the observed optical-to-X-ray spectral index is found to be variable with time. In the highest signal-to-noise observation we detected highly ionized X-ray absorbing material outflowing much faster (u(sub X) approx. 16 500 km/s) than the UV absorbing one (u(sub uv) approx. 5,000 km/s). This highly ionized absorber is found to be variable on very short (a few kiloseconds) time scales. Conclusions. Our findings are qualitatively consistent with line driven accretion disk winds scenarios. Our observations have opened the time-resolved X-ray spectral analysis field for mini-BAL QSOs; only with future deep studies will we be able to map the dynamics of the inner flow and understand the physics of AGN winds and their impact on the environment.

    Full Text Available La hemorragia postparto es un importante contribuyente a la morbilidad materna y sigue siendo la principal causa de mortalidad materna a nivel mundial; en la mayoría de los casos aparece en forma espontanea inmediata a la ocurrencia del parto, y el porcentaje mayor se refiere a la hipotonía uterina, que es rebelde a la aplicación de medidas convencionales como el masaje uterino, oxitócicos, prostaglandinas etc.Las pautas para el manejo de la hemorragia postparto implican medidas graduales desde enfoques farmacológicos hasta los quirúrgicos. El método de taponamiento uterino utilizando “balones hemostáticos” se ha añadido recientemente al arsenal de tratamiento de la hemorragia postparto. Hay varios balones disponibles, incluyendo el Balón de Bakri, Foley,Sengstaken-Blakemore, Rusch, entre otros. Este artículo estudia estas tecnologías de taponamiento uterino en el tratamientode la hemorragia postparto y especialmente el método del Balón intrauterino aplicado en el Hospital Materno Infantil German Urquidi como una alternativa más ante esta complicación.

    Ceftobiprole (BAL9141) is an investigational cephalosporin active against methicillin- and vancomycin-resistant staphylococci administered as a water-soluble prodrug, ceftobiprole medocaril (BAL5788). Using an immunocompetent murine pneumonia model of Haemophilus influenzae, Enterobacter cloacae, or extended-spectrum beta-lactamase (ESBL) nonproducing or producing Klebsiella pneumoniae pneumonia, we compared results of treatment with ceftobiprole medocaril (71 mg/kg, sc, qid), ceftriaxone (50 mg/kg, im, bid), or cefepime (50 mg/kg, ip, q.i.d.). Results were expressed as median and 25th to 75th percentile log10 colony forming units per gram of lung tissue. Ceftobiprole, ceftriaxone, and cefepime were each more active than was no treatment and were equally active for treatment of experimental H. influenzae, E. cloacae, or ESBL-nonproducing K. pneumoniae pneumonia. For ESBL-producing K. pneumoniae, no differences were detected between no treatment and treatment with ceftobiprole, ceftriaxone, or cefepime. Ceftobiprole is active against H. influenzae, E. cloacae, and ESBL-nonproducing K. pneumoniae in an immunocompetent experimental murine pneumonia model.

    New solid-phase strategies have been developed for the synthesis of lidocaine (1) and procainamide (2) analogues, using backbone amide linker (BAL) anchoring. Both sets were prepared starting from a common resin-bound intermediate, followed by four general steps: (i) attachment of a primary aliphatic or aromatic amine to the solid support via reductive amination (as monitored by a novel test involving reaction of 2,4-dinitrophenylhydrazine with residual aldehyde groups); (ii) acylation of the resultant secondary amine; (iii) displacement of halide with an amine; and (iv) trifluoroacetic acid-mediated release from the support. A manual parallel strategy was followed to provide 60 novel compounds, of which two dozen have not been previously described. In most cases, initial crude purities were >80%, and overall isolated yields were in the 40-88% range.

    Ricinulei is an order of Arachnida composed of rare and little known species. The species of Ricinulei possess a rich variety of fine integumentary structures that have been poorly investigated in a few species. Besides, several structures are still undescribed and their function not yet addressed. In this paper we provide a detailed study of the integumentary morphology of Cryptocellus bordoni Dumitresco and Jurvara-Bals, 1976 using Light and Scanning Electron Microscopy. We describe and present photos of the new and already known fine integumentary structures. We compare the new structures to those previously described for other Ricinulei species and discuss their taxonomic implications and the placement of C. bordoni in the genus Cryptocellus.

It highlights the value of Bascuñán to the intellectual history of the discipline, for being the first Hispanic American thinker who without hesitation supported the autonomous status of public administration and for conceiving it as scientific knowledge under an ontic approach, where his being is endowed with an identity and able to develop principles. It is concluded that the work of Bascuñán is one of the most developed within the discipline during the 1960s,above all because it considers public administration as an autonomous science and social science.

    We study the dramatic decrease in iron absorption strength in the iron low-ionization broad absorption line quasar SDSS J084133.15+200525.8. We report on the continued weakening of absorption in the prototype of this class of variable broad absorption line quasar, FBQS J140806.2+305448. We also report a third example of this class, SDSS J123103.70+392903.6; unlike the other two examples, it has undergone an increase in observed continuum brightness (at 3000~\\AA\\ rest-frame) as well as a decrease in iron absorption strength. These changes could be caused by absorber transverse motion or by ionization variability. We note that the \\mgii\\ and UV \\feii\\ lines in several FeLoBAL quasars are blueshifted by thousands of \\kms\\ relative to the \\Hb\\ emission line peak. We suggest that such emission arises in the outflowing winds normally seen only in absorption.

    Samples of CaBAl glass with composition of (25-x)CaO-50B2O3-15Al2O3-10CaF2-xSm2O3, with Sm2O3 concentration varying from 0.5 to 7 wt%, were prepared by using melt-quenching method in air atmosphere. The samples were prepared with different concentrations of Sm2O3, aiming to understand how the dopant changes the optical and spectroscopic properties of the glass. The doped CaBAl glasses were studied by means of volumetric density measurements, refractive index, optical absorption, luminescence at room temperature, luminescence as function of the temperature and radiative lifetime. All results were discussed in function of Sm2O3 concentration. The measured volumetric density and polarizability showed an increase with Sm2O3 doping. The refractive index showed a small increase due to RE doping, although within the errors. The absorption bands were attributed to Sm3+ transitions from the ground state 6H5/2 to the various excited states. The luminescence spectra present emission bands assigned to the appropriate electronic f-f transitions of Sm3+ ions; there are four emission bands at 565, 602, 649 and 710 nm. The luminescence quenching was observed up to 2 wt% of Sm2O3. The O/R ratio as function of the Sm2O3 concentration showed changes in the symmetry site with addition of Sm2O3. The CIE 1931 diagram presented a reddish-orange shift color with Sm2O3 doping. The luminescence intensity presents a decrease with temperature increase for all studied samples. The experimental lifetime decreases with the increase of Sm2O3, mainly due to ion-ion interaction.

    Full Text Available El presente artículo identifica una relación histórica y sistémica entre el ejercicio del poder político y una “máquina de guerra caníbal” que se apropia de formas y conceptos propios del ámbito de la brujería y de la relación con lo divino. Se propone que la violencia material y simbólica ha sido el eje de todos los intercambios sociales de la modernidad, en la que se despliega un aparato de muerte y sufrimiento justificado en el progreso, la libertad y el mercado capitalista, bajo una lógica que evoca el sacrificio a los dioses y que sacraliza el orden liberal democrático. A partir del proceso de colonización del Nuevo Mundo, el lucro de la guerra y la ambición por explotar la exuberante riqueza del territorio amerindio hicieron que el hombre blanco caníbal (una figura común en los imaginarios no-occidentales desatara esa máquina de guerra que devora personas y recursos para alimentar al Estado colonial. En la contemporaneidad, el uso de altas tecnologías envuelve a las acciones bélicas con un halo de misterio que hace mímesis de los imaginarios de la magia y la hechicería, lo cual supone la propagación deliberada de una mística que genera miedo y caos social y que conviene a los intereses militares. Después de cinco siglos de coalición entre el poder político y la violencia, pareciera que la máquina de guerra caníbal no se ha saciado y reclama cada vez más sangre en nombre de la libertad y el progreso.

    Eu2O3 doped CaBAL glasses (x Eu2O3) - (25-x) CaO - (50) B2O3 - (15) Al2O3 - (10) CaF2 (x = 0, 5, 1, 2, 3, 4, 5, 10 wt%) were prepared by using conventional melt-quenching and studied by means of density measurements, refractive index, optical absorption, luminescence and radiative lifetime. The results are discussed in terms of Eu2O3 content. The incorporation of Eu2O3 leads to an increase in the electronic polarizability and the refractive index. A linear increase with Eu2O3 content was observed in the optical absorption coefficient at 394 nm. The luminescence spectra present typical Eu3+ emission and do not present quenching up to 10 wt%. The luminescence ratio R/O I(5D0 → 7F2)/I(5D0 → 7F1) presents an increase with Eu2O3 doping; it indicates a reduction in local symmetry around the Eu3+ ions. The CIE 1931 diagram presents a red shift and an increase of color purity with Eu2O3 addition. The luminescence as a function of temperature shows an increase of 25% in the luminescence intensity for the Eu0.5 sample, at 592 nm. The radiative lifetime at 614 nm shows an exponential decay due to the reduction of the interionic distance Eu3+ - Eu3+ and the increase of the ion-ion interaction.

    We present high-resolution observations, using both the European VLBI Network (EVN) at 1.7-GHz, and the Very Long Baseline Array (VLBA) at 5 and 8.4-GHz to image radio structures of 14 compact sources classified as broad absorption line (BAL) quasars based on the absorption index (AI). All source but one were resolved, with the majority showing core-jet morphology typical for radio-loud quasars. We discuss in details the most interesting cases. The high radio luminosities and small linear sizes of the observed objects indicate they are strong young AGNs. Nevertheless, the distribution of the radio-loudness parameter, log(Ri), of a larger sample of AI quasars shows that the objects observed by us constitute the most luminous, small subgroup of AI population. Additionally we report that for the radio-loudness parameter, the distribution of AI quasars and those selected by using the traditional balnicity index (BI), BI quasars differ significantly. Strong absorption is connected with the lower log(Ri), and thus ...

    Full Text Available La obesidad es considerada una enfermedad crónica, epidémica, y de difícil tratamiento. Ante el alto índice de fracasos de los métodos conservadores, y por otra parte, la inevitable morbimortalidad y secuelas ligadas a la cirugía, surgen nuevas técnicas poco invasivas destinadas a contribuir al tratamiento de esta enfermedad. La más implantada actualmente es el Balón Intragástrico, considerado más eficaz que el tratamiento conservador, con menos riesgo que la cirugía pero que adolece a día de hoy de una falta de consenso sobre sus indicaciones y escasa información sobre sus limitaciones, al tiempo que su aparición mediática ha propiciado su gran difusión en los 4 últimos años. En este trabajo se realiza una revisión crítica y se señalan las limitaciones de este tratamiento con base a la evidencia aportada por los estudios publicados hasta la fecha. Como conclusión de dicha revisión, se emiten una serie de recomendaciones respecto a la técnica y sus indicaciones, requisitos materiales y humanos, necesidad de Equipo Multidisciplinar así como del control y seguimiento adecuados.

  6. SimBAL: A Spectral Synthesis Approach to Analyzing Broad Absorption Line Quasar Spectra

    2017-01-01

    Broad Absorption Line quasars (BALQSOs) show blueshifted absorption lines in their rest-UV spectra, indicating powerful winds emerging from the central engine. These winds are essential part of quasars: they can carry away angular momentum and thus facilitate accretion through a disk, they can distribute chemically-enriched gas through the intergalactic medium, and they may inject kinetic energy to the host galaxy, influencing its evolution. The traditional method of analyzing BALQSO spectra involves measuring myriad absorption lines, computing the inferred ionic column densities in each feature, and comparing with the output of photonionization models. This method is inefficient and does not handle line blending well. We introduce SimBAL, a spectral synthesis fitting method for BALQSOs, which compares synthetic spectra created from photoionization model results with continuum-normalized observed spectra using Bayesian model calibration. We find that we can obtain an excellent fit to the UV to near-IR spectrum of the low-redshift BALQSO SDSS J0850+4451, including lines from diverse ionization states such as PV, CIII*, SIII, Lyalpha, NV, SiIV, CIV, MgII, and HeI*.

    Ceftobiprole medocaril [BAL 5788, RO 65-5788, JNJ 30982081] is a prodrug in phase III clinical development with Basilea Pharmaceutica and Cilag AG (Johnson & Johnson) for the potential treatment of serious bacterial infections, including methicillin-resistant Staphylococcus aureus (MRSA). Ceftobiprole medocaril is the water-soluble prodrug of the pyrrolidinone cephalosporin, ceftobiprole [BAL 9141, RO 63-9141]. Because of the low water solubility of ceftobiprole, its clinical application was limited and Basilea began its investigations into ceftobiprole medocaril for further development. Ceftobiprole medocaril is being developed for IV administration and is currently undergoing phase III trials for complicated skin and skin structure infections (including MRSA) and hospital-acquired (nosocomial) pneumonia. Ceftobiprole medocaril has a broad spectrum of activity against Gram-positive bacteria (including methicillin-resistant staphylococci, penicillin-resistant pneumococci and Enterococcus faecalis) and Gram-negative bacteria. Ceftobiprole medocaril inhibits all transpeptidases, including the penicillin-binding protein (PBP) 2a, by a unique combination of features. PBP 2a is the primary enzyme responsible for beta-lactam drug resistance in MRSA; PBP 2a also acts as a key defense mechanism by interacting with the bacterial cell wall to form a chemical barricade that is impervious to antibiotics. Ceftobiprole medocaril has been designed specifically to bind to this penicillin-resistant target. Ceftobiprole medocaril is bactericidal and has not shown resistance development in vitro or in stringent animal models. Studies conducted by Basilea have demonstrated that ceftobiprole medocaril is readily converted to ceftobiprole, and shows markedly improved water solubility. In February 2005, Basilea Pharmaceutica AG entered into an exclusive worldwide agreement with Cilag AG International (Johnson & Johnson) to develop, manufacture and market ceftobiprole medocaril.

    Full Text Available Background Bacillus cereus is a Gram-positive spore-forming bacterium, which causes food poisoning. Spores enable the persistence of B. cereus in the environment, and B. cereus strains can tolerate adverse environmental conditions, such as temperature and insufficient nutrients. B. cereus causes food poisoning via the production of two enterotoxins. Most isolates produce toxins leading to diarrhea (enterotoxins and vomiting (emetic forms. Diarrhea is caused by the production of three different heat-labile enterotoxins: HBL, NHE, and cytotoxin K. A heat-stable toxin, cereulide, is responsible for emesis. Objectives This study aimed to detect enterotoxigenic B. cereus isolates in cheese samples using the polymerase chain reaction (PCR. Materials and Methods Two-hundred pasteurized (n = 100 and nonpasteurized (n = 100 cheese samples were collected. The initial isolation was performed on PEMBA specific medium. Antibiotic susceptibility testing was performed using several antibiotic disks, according to the guidelines of the Clinical Laboratory and Standards Institute. Specific primers amplifying the hblA enterotoxin-encoding gene and bal hemolysin-encoding gene were used for the molecular detection of the toxins. Results Ten samples were positive for the presence of B. cereus, with both Gram staining and biochemical reactions. All the isolates were resistant to penicillin and ampicillin but susceptible to vancomycin, erythromycin, and ciprofloxacin. Six and three isolates were resistant to tetracycline and trimethoprim-sulfamethoxazole, respectively. The hblA and bal genes were amplified in all the B. cereus isolates. Conclusions The prevalence of B. cereus among the cheese samples was low. All the isolates were positive for genes encoding the hblA enterotoxin and bal toxin.

    Full Text Available One of the entomopatogenous fungus types commonly observed and showed potency as myco-insectiside is Beauveria bassiana(Bals. Vuill.In order to support effectiveness and patogenous activity of B. bassiana, it is necessary to add a carrying agent that protects its spores from ultra violet ray. This study aims to investigate the effect of storage temperature on viability of B. Bassianaspores on the carrier material. The observation was carried out in the Laboratory of Plant Diseases, Indonesian Coffee and Cocoa Research Institute. The research was arranged in completely randomized design by three factors. The first factor was carrier (C, that consists of C1 = rice flour, C2 = maize flour and C3 = tapioca flour. The second factor was dosage (D, that consists of D1 = 1 g B. bassiana+ 1 g carrier; D2 = 1 g B. bassiana+ 5 g carrier and D3 = 1 g B. bassiana+ 10 g carrier. The third factor was temperature of the storage (T,that consists of T1 = 5oC; T2 = 23oC and T3 = 29oC. Viability of B. Bassiana spores was examined by observing development of 100 blastopores randomly and determined under light microscope with 400 times magnification. Observation was conducted in two replicates after the spores of B. bassiana were kept in the storage for 2, 4, 8 and 16 weeks. The result showed that by adding 1 g tapioca flour and temperature of storage of 5oC was potentiall in keeping viability of B. bassianaspores at least for 2 months. It was due to that tapioca flour gave better effect than rice and maize flours in keeping the storage and appropriate low temperature. Viability of B. bassianaspores decreased with increasing carrier dosage, temperature and duration of the storage. Whereas, storage at 5oC was found to be a better condition in keeping viability of dry pure B. bassianaspores longer than conditions of 23o and 29oC.

    Full Text Available Background: The intragastric balloon is widely used for weight reduction in obese patients, but results are variable. We describe our results enhancing the importance of a Multidisciplinary Team (MT taking part in the treatment. Methods: A retrospective review was done concerning a total of 119 balloons , placed in 116 patients, under endoscopic control and conscious sedation, from May 2001 until August 2006. 49 patients were prepared and recommended to be followed by a MT in a physical unit, at least every 15 days during 6 months. 67 were indicated and followed by other colleagues, without MT. Removal was performed 6 months later. Results: Concerning our 49 patients, mean age was 38, 1 years, 31 female and 18 males, with BMI ranged between 32 and 63, average of 42. The average decrease of weight excess was 31, 85% (-4, 45-80, 4%, and the BMI diminished 5,3 points (from 13,6 to gain of 0,9. The treatment failed in 34,6 % of our patients -including 4 patients lost of follow-up (8, 16%-, compared with 53, 8% of patients without structured MT for selection and follow-up. Physical exercise enhanced markedly the results with 45, 8% of excess of weight loss in women and 39, 7% in males, compared with 14, 6 and 15, 6% in patients who didn't follow the program. The weight loss was mostly fat mass, 89,9% in men and 75,6% in women.- The results maintenance was obtained in 40% of patients one year later. There were no major complications; one balloon had to be removed at 3 weeks because of intolerance, another at 5 months because of gastroesophageal reflux. Conclusions: BIB is an effective help to achieve a short term weight loss in obese patients; nevertheless, good and long lasting results will depend on the modification of life style obtained by a multidisciplinary approach.Antecedentes: el balón intragástrico se usa ampliamente para la reducción de peso de pacientes obesos pero sus resultados son variables.

    Full Text Available At the time Zeta was ruled by the local lords of the Balšić family, in the late fourteenth and the first half of the fifteenth century, the islets in Lake Scutari (Skadarsko jezero in Zeta were lively centres of monastic life. The paper looks at the forms of monastic life as suggested by the spatial organization and architecture of the monastic complexes founded by the Balšićs, and by the surviving written sources. The most important documentary source is the correspondence between Jelena Balšić and her spiritual father, Nikon, preserved in the manuscript known as Gorički zbornik (Gorica Collection. The letters show that Lake Scutari was a centre of monasticism touched by hesychast-inspired spirituality where both the eremitic and coenobitic ways of life were practised.

    Full Text Available OBJECTIVE: To compare 28-day mortality rates and clinical outcomes in ICU patients with ventilator-associated pneumonia according to the diagnostic strategy used. METHODS: This was a prospective randomized clinical trial. Of the 73 patients included in the study, 36 and 37 were randomized to undergo BAL or endotracheal aspiration (EA, respectively. Antibiotic therapy was based on guidelines and was adjusted according to the results of quantitative cultures. RESULTS: The 28-day mortality rate was similar in the BAL and EA groups (25.0% and 37.8%, respectively; p = 0.353. There were no differences between the groups regarding the duration of mechanical ventilation, antibiotic therapy, secondary complications, VAP recurrence, or length of ICU and hospital stay. Initial antibiotic therapy was deemed appropriate in 28 (77.8% and 30 (83.3% of the patients in the BAL and EA groups, respectively (p = 0.551. The 28-day mortality rate was not associated with the appropriateness of initial therapy in the BAL and EA groups (appropriate therapy: 35.7% vs. 43.3%; p = 0.553; and inappropriate therapy: 62.5% vs. 50.0%; p = 1.000. Previous use of antibiotics did not affect the culture yield in the EA or BAL group (p = 0.130 and p = 0.484, respectively. CONCLUSIONS: In the context of this study, the management of VAP patients, based on the results of quantitative endotracheal aspirate cultures, led to similar clinical outcomes to those obtained with the results of quantitative BAL fluid cultures.

    San Cristóbal volcano in northwest Nicaragua is one of the most active basaltic-andesitic stratovolcanoes of the Central American Volcanic Arc (CAVA). Here we provide novel constraints on the volcano's magmatic plumbing system, by presenting the first direct measurements of major volatile contents in mafic-to-intermediate glass inclusions from Holocene and historic-present volcanic activity. Olivine-hosted (forsterite [Fo] 1500 μg/g) found in Nicaragua at Cerro Negro, Nejapa, and Granada. Models of H2O and CO2 solubilities constrain the degassing pathway of magmas up to 425 MPa ( 16 km depth), which includes a deep CO2 degassing step (only partially preserved in the MI record), followed by coupled degassing of H2O and S plus crystal fractionation at magma volatile saturation pressures from ∼ 195 to < 10 MPa. The variation in volatile contents from San Cristóbal MI is interpreted to reflect (1) Holocene eruptive cycles characterized by the rapid emplacement of basaltic magma batches, saturated in volatiles, at depths of 3.8-7.4 km, and (2) the ascent of more-differentiated and cogenetic volatile-poor basaltic andesites during historic-present eruptions, having longer residence times in the shallowest (< 3.4 km) and hence coolest regions of the magmatic plumbing system. We also report the first measurements of the compositions of noble-gas isotopes (He, Ne, and Ar) in fluid inclusions in olivine and pyroxene crystals. While the measured 40Ar/36Ar ratios (300-304) and 4He/20Ne ratios (9-373) indicate some degree of air contamination, the 3He/4He ratios (7.01-7.20 Ra) support a common mantle source for Holocene basalts and historic-present basaltic andesites. The magmatic source is interpreted as generated by a primitive MORB-like mantle, that is influenced to variable extents by distinct slab fluid components for basalts (Ba/La 76 and U/Th 0.8) and basaltic andesites (Ba/La 86 and U/Th 1.0) in addition to effects of magma differentiation. These values for the

    Full Text Available En Humanismo burgués y humanismo proletario, publicado por primera vez en 1938, Aníbal Ponce examina dos concepciones contrapuestas del humanismo. Entre los muchos méritos del estudio de Ponce se pueden destacar tres en particular. En primer lugar, el análisis de Ponce pone de manifiesto que el humanismo del Renacimiento (“humanismo burgués” no sólo se ha prestado a usos ideológicos, sino que surgió por primera vez precisamente en la forma de una ideología. En segundo lugar, pone de manifiesto la necesidad de precisar el tipo de humanismo que uno reivindica al invocar este concepto. Por último, nos recuerda que un humanismo realmente emancipador no es posible si no se dan determinadas condiciones históricas y sociales.

    A new blue-emitting phosphor of Eu{sup 2+}-activated hexa-aluminate CaZrBAl{sub 9}O{sub 18} was synthesized by a conventional solid-state reaction method. The crystalline phase formation was confirmed by X-ray powder diffraction (XRD) measurements. The photoluminescence excitation and emission spectra, the luminescence decay curves and the time-resolved spectra of CaZrBAl{sub 9}O{sub 18}:Eu{sup 2+} were taken to investigate the luminescence characteristics. The dependence of CaZrBAl{sub 9}O{sub 18}:Eu{sup 2+} luminescence intensity on the Eu{sup 2+} doping concentrations was investigated. This phosphor can be efficiently excited by UV light and presents blue luminescence. There is one kind of Eu{sup 2+} luminescence center in the lattices, which was confirmed by the time-resolved luminescence spectra. The temperature-dependent luminescence intensity was measured and the activation energy (ΔE) for thermal quenching was reported. The phosphor shows high luminescence intensity and an excellent thermal stability on temperature quenching. Eu{sup 2+}-doped hexa-aluminate CaZrBAl{sub 9}O{sub 18} presents bright blue-emitting luminescence with high thermal quenching; only one Eu{sup 2+} center was confirmed in this hexa-aluminate lattices.

    Pathogenicity of the fungi Metarrhizium anisopliae (Metsch.) Sorokin and Beauveria bassiana (Bals.) Vuillemin to stink bug Scaptocoris carvalhoi Becker, 1967 was evaluated under laboratory and greenhouse conditions. Experiments were carried out at EMBRAPA Agropecuaria Oeste, Dourados, Mato Grosso do Sul State, Brazil, in 2003. Ten M. anisopliae and eleven B. bassiana isolates were evaluated in laboratory using a completely randomized experimental design with five replicates (10 adults and 5 nymphs/plot). The pathogenicity of M. anisopliae isolate (Ma69) was also separately evaluated against nymphs and adults in laboratory and greenhouse. The stink bug mortality levels were higher for M. anisopliae isolates (between 73.3% and 94.7% than for B. bassiana isolates (between 10.7% and 78.7%). In greenhouse, stink bug mortality due to the M. anisopliae isolate (Ma69) was 57.3%, and there was no difference of mortality for nymphs and adults of stink bug in laboratory. However, in greenhouse, mortality levels were significantly higher (p<0,05) for nymphs (38,4%) than for adults (16,2%). From these data, we conclude that M. anisopliae isolate Ma69 was efficient to control S. carvalhoi in laboratory and in greenhouse, thus being a promising choice for use as a microbial insecticide under field conditions.

    Aflatoxins, the secondary metabolites produced by species of naturally occurring Aspergilli, are commonly found in food such as cereals, dried fruits and juice, wine, beer and spices. They are hepatotoxic and are well known human carcinogens based on evidence from human studies. Aflatoxins are an environmental risk factor for the development of hepatocellular carcinoma (HCC). Chronic hepatitis B-infected patients are at increased risk of cirrhosis, hepatic failure and liver cancer. This study was designed to determine the serum aflatoxin B1 (AFB1 ), aflatoxin B2 (AFB2 ), aflatoxin G1 (AFG1 ) and aflatoxin G2 (AFG2 ) concentrations using high-pressure liquid chromatography (HPLC) in hepatitis B-infected patients with or without cirrhosis and liver cancer, alongside healthy controls in Balıkesir, Turkey. The mean AFB1 and total AF levels in patients without liver cancer and cirrhosis were significantly higher than healthy controls. The mean AFB1 and total AF levels in patients with chronic hepatitis B and HCC were significantly higher than infected patients with or without cirrhosis. These results suggest that patients with chronic hepatitis B who are exposed to AFs are at increased risk for developing HCC, which might be prevented by reducing consumption of contaminated foods.

    We report on the first detection of extreme-ultraviolet (EUV) absorption variability in the NeVIII 770,780 mini-broad absorption line (mini-BAL) in the spectrum of the quasar (QSO) PG 1206+459. The observed equivalent width (EW) of the NeVIII doublet show a ~4 sigma variation over a timescale of 2.8 months in the QSO's rest-frame. Both members of the NeVIII doublet exhibit non-black saturation, indicating partial coverage of the continuum source. An increase in the NeVIII covering fraction from f_c = 0.59\\pm0.05 to 0.72\\pm0.03 is observed over the same period. The NeVIII profiles are too highly saturated to be susceptible to changes in the ionization state of the absorbing gas. In fact, we do not observe any significant variation in the EW and/or column density after correcting the spectra for partial coverage. We, thus, propose transverse motions of the absorbing gas being the cause of the observed variability. Using a simple model of a transiting cloud we estimate a transverse speed of ~1800 km/s.

    Full Text Available The German naturalist Juan Cristóbal Gundlach (1810–1896 conducted, while a resident of Cuba, two expeditions to Puerto Rico in 1873 and 1875–6, where he explored the southwestern, western, and northeastern regions of this island. Gundlach made representative collections of the island’s fauna, which formed the nucleus of the first natural history museums in Puerto Rico. When the natural history museums closed, only a few specimens were passed to other institutions, including foreign museums. None of Gundlach’s and few of his contemporaries’ specimens have survived in Puerto Rico. We located 191 bird specimens (43 species collected there by Gundlach, all of which are in foreign institutions, especially Museum für Naturkunde Berlin. Here we list all located specimens and include data associated with them. Six new species were described out of the Gundlach collections from Puerto Rico, three of which are still taxonomically recognized today. Information about the types of those taxa is given.

    The wide-ranging physiology and large genetic variability observed for prokaryotes is largely attributed, not to the prokaryotic genome itself, but rather to mechanisms of lateral gene transfer. Cassette PCR has been used to sample the integron/gene cassette metagenome from different natural environments without laboratory cultivation of the host organism, and without prior knowledge of any target protein sequence. Since over 90% of cassette genes are unrelated to any sequence in the current databases, it is not clear whether these genes code for folded functional proteins. We have selected a sample of eight cassette-encoded genes with no known homologs; five have been isolated as soluble protein products and shown by biophysical techniques to be folded. In solution, at least three of these proteins organise as stable oligomeric assemblies. The tertiary structure of one of these, Bal32a derived from a contaminated soil site, has been solved by X-ray crystallography to 1.8 A resolution. From the three-dimensional structure, Bal32a is found to be a member of the highly adaptable alpha+beta barrel family of transport proteins and enzymes. In Bal32a, the barrel cavity is unusually deep and inaccessible to solvent. Polar side-chains in its interior are reminiscent of catalytic sites of limonene-1,2-epoxide hydrolase and nogalonic acid methyl ester cyclase. These studies demonstrate the viability of direct sampling of mobile DNA as a route for the discovery of novel proteins.

    An equiatomic FeSiBAlNi amorphous high-entropy alloy (HEA) was fabricated by mechanical alloying (MA). A fully amorphous phase was obtained in the FeSiBAlNi HEA after 240 h of MA. The bulk FeSiBAlNi samples were sintered by spark plasma sintering (SPS) at 520 and 1080°C under a pressure of 80 MPa. The sample sintered at 520°C exhibited an amorphous composite structure comprising solid-solution phases (body-centered cubic (bcc) and face-centered cubic (fcc) phases). When the as-milled amorphous HEA was consolidated at 1080°C, another fcc phase appeared and the amorphous phase disappeared. The sample sintered by SPS at 1080°C exhibited a slightly higher melting temperature compared with those of the as-milled alloy and the bulk sample sintered at 520°C. The corrosion behaviors of the as-sintered samples were investigated by potentiodynamic polarization measurements and immersion tests in seawater solution. The results showed that the HEA obtained by SPS at 1080°C exhibited better corrosion resistance than that obtained by SPS at 520°C.

Para tanto, optamos por uma orientação epistemológica apoiada na fenomenologia de Edmund Husserl e em autores afinados com a fenomenologia proposta por esse filósofo. As entrevistas semiestruturadas em profundidade constituíram a técnica de pesquisa utilizada. O que há de comum nas falas das bailarinas é a referência a um corpo ideal centrado nas produções feitas pelas grandes companhias de balé. Nessas percepções, o corpo desejado e ideal para o balé clássico pode ser tanto inato à pessoa, quanto construído e transformado com muito esforço e dedicação pela bailarina.

    Full Text Available RESUMOObjetivo:Testar a concordância entre dispositivos artesanais e um manômetro especificamente projetado para esse fim.Métodos:Testamos em 79 sujeitos a concordância entre as mensurações realizadas com 2 dispositivos artesanalmente adaptados para medir a pressão de balão dos tubos endotraqueais e as obtidas com uso de um manômetro específico para esse fim. A pressão de balão foi medida com um manômetro comercial e com dois dispositivos artesanais montados a partir de esfigmomanômetro aneroides. Os dados foram comparados utilizando os testes de Wilcoxon e Spearman, o coeficiente de correlação intraclasse e a análise do limite de concordância.Resultados:As pressões do balão medidas com os dispositivos artesanais foram significantemente diferentes das medidas obtidas com o dispositivo comercial (as pressões foram mais elevadas nas mensurações obtidas com o dispositivo artesanal 1 e mais baixas nas avaliações realizadas com o dispositivo artesanal 2. O coeficiente de correlação intraclasse entre o dispositivo comercial e os dispositivos 1 e 2 foi excelente (0,8; p < 0,001 e bom (0,66; p < 0,001, respectivamente. No entanto, os gráficos de Bland-Altman demonstraram limites amplos de concordância entre os dispositivos 1 e 2 e o dispositivo comercial.Conclusão:Os manômetros artesanais não proporcionam mensurações precisas da pressão do balão, quando comparados a um dispositivo específico para esse fim e, portanto, não devem ser utilizados na avaliação de pacientes mecanicamente ventilados em substituição aos manômetros comerciais específicos para avaliação da pressão do balão.

    Full Text Available Fifty strains of the entomopathogenic fungi Beauveria bassiana (Bals. Vuill. and Metarhizium anisopliae (Metsch. Sorok. were tested against the termite Cornitermes cumulans. In the first phase of the experiments, several bioassays were conducted and the five best strains were selected. The criterion for strain selection during this phase was the confirmed mortality above 50% five days after application of the fungus. Three M. anisopliae and two B. bassiana strains were the most virulent. The second phase of the experiments consisted of a bioassay and a conidial production test using a rice medium. The best M. anisopliae and B. bassiana strains were selected using both the confirmed insect mortality nine days after application of the fungus and the yield of conidia. Considering results from the bioassay, M. anisopliae 1037 showed the highest confirmed (57.8% and total (89.2% mortalities after nine days. Among the B. bassiana strains, 447 was the most virulent with confirmed and total mortalities of 45.9% and 89.8%, respectively. M. anisopliae 1037 had the highest conidial yield with mean of 3.37 x 10(12 conidia/kg of rice, followed by B. bassiana strain 447 with 2.66 x 10(12 conidia/kg of rice. The M. anisopliae strain 1037 was the highest virulent followed by B. bassiana strain 447. This strains showed the greatest potential as agents to be used in biological control programs against C. cumulans.Nesta pesquisa foram testados cinqüenta isolados dos fungos entomopatogênicos Beauveria bassiana (Bals.

    Full Text Available L’une des hypothèses admises implicitement dans la plupart des études sur l’adaptation est que le spectateur sait d’avance que le film est une adaptation, ou qu’il connaît le roman dont le film est adapté. Or, bien plus fréquemment, le film s’offre comme un substitut de roman à un spectateur qui ne l’a pas lu. Adoptant une approche pragmatique, l’article qui suit pose ces questions à propos de deux adaptations de Madame Bovary : à quoi reconnaît-on qu’un récit filmique est non seulement une transposition audiovisuelle des signes écrits, mais aussi une lecture de ceux-ci ? Y a-t-il des signes ostensibles dans lesquels se repéreraient une intention communicative, une vision de l’œuvre ?

    Full Text Available La obesidad es considerada una enfermedad crónica, epidémica, y de difícil tratamiento. Ante el alto índice de fracasos de los métodos conservadores, y por otra parte, la inevitable morbimortalidad y secuelas ligadas a la cirugía, surgen nuevas técnicas poco invasivas destinadas a contribuir al tratamiento de esta enfermedad. La más implantada actualmente es el Balón Intragástrico, considerado más eficaz que el tratamiento conservador, con menos riesgo que la cirugía pero que adolece a día de hoy de una falta de consenso sobre sus indicaciones y escasa información sobre sus limitaciones, al tiempo que su aparición mediática ha propiciado su gran difusión en los 4 últimos años. En este trabajo se realiza una revisión crítica y se señalan las limitaciones de este tratamiento con base a la evidencia aportada por los estudios publicados hasta la fecha. Como conclusión de dicha revisión, se emiten una serie de recomendaciones respecto a la técnica y sus indicaciones, requisitos materiales y humanos, necesidad de Equipo Multidisciplinar así como del control y seguimiento adecuados.Obesity is considered a chronic and epidemic illness, hece difficult to treat.

    Full Text Available A current tendency in Spanish Golden Age theatre studies is dramatic segmentation. In this sense, we must emphasize Marc Vitseʼs methodology, which suggests structuring the play according to the versification changes. We are going to put into practice this theory with a work by an unknown playwright: Renegado, rey y mártir by Cristóbal de Morales. We will verify that versification does actually help when dividing and hierarchising the different moments of the play. At Renegado, rey y mártir violence is important due to the fact that it causes the strophic changes and structures the plot.

It is based upon the premise that such practices are configured (in this organization’s daily management practices. In order to achieve the proposed objective, four questions considered to be recursive in this field were used as guidelines: (a What is strategy? (b Who is the strategist? (c What do strategists do? (d What can explain an analysis of strategists and their actions? As methodological support, an ethnography was conducted. In addition, the Grounded Theory procedure was used to develop the proposal of bringing about a substantial concept of strategy. A situational analysis was also done (Clarke, 2005 and at the end of the study, three organizational spheres within the Corpo de Balé group: its Ballet Group sphere, its Citizen sphere, and its Dance School sphere. The practices and relationships constructed between these and the subjects that actually included them in the organization under study were also identified. Thus, a relational scheme was established, involving the observed practices and the individual and collective actors. Based on the analysis of the relational scheme a strategy concept was elaborated for the Corpo de Balé group.

    Jáuregui, Carlos A.

    2015-12-01

    Full Text Available Oswaldo Costa was a key member of the Brazilian modernist Antropofagia (Anthropophagy movement of the late 1920s, yet he has been largely forgotten by critics and marginalized from national cultural history. Costa articulated —as no other member of the movement did, including his famous leader Oswald de Andrade— an Antropofagia intellectually engaged in what we call a cannibal critique of colonial modernity and Occidentalism. Costa’s Antropofagia cannibalized the historical archive, reading against the grain of a triumphant Western imperial history. Throughout his contributions to the Revista de Antropofagia, he questioned Brazil’s cultural allegiance to Europe, pointed out the existence of asynchronous temporalities within Brazil, and defied Eurocentric notions of civilization and progress that ideologically structure Brazilian nationalism in the ninetieth and twentieth centuries. He also enacted an anthropophagous re-reading of Brazilian historiography against its celebration of colonialism and proposed the necessity of a cultural decolonization. This article analyzes Costa’s principal contributions to Antropofagia and rescues his hitherto overlooked countercolonial thought from the oblivion of collective forgetting. Moreover, it examines Costa’s significant view of Brazilian modernity as a perfidious armistice with other barbarous temporalities, and of the Westernization of Brazil as a deceptive appearance that hides ever-present colonial antagonisms.Oswaldo Costa fue un miembro fundamental del movimiento modernista Antropofagia de finales de la década de 1920. Pese al olvido crítico de su obra y a su exclusión de la historia cultural brasileña, Costa articuló —como acaso ningún otro miembro del movimiento, incluyendo a su famoso líder Oswald de Andrade— una Antropofagia-otra, intelectualmente trabada en lo que denominamos una crítica caníbal de la modernidad colonial y del Occidentalismo.

    Au/H similarity is a hot topic in chemistry. Here, we report the theoretical prediction of new members of the Au/H analogy family:covalent B2Au4, ionic Al2Au4, and BAlAu4. A comparative study of the geometric and electronic structures of electron-deficient B2Au4, Al2Au4, and BAlAu4 was performed based on density and wave functional theories. Detailed orbital analyses, adaptive natural density partitioning (AdNDP), and electron localization function (ELF) analyses were performed. Ab initio theoretical evidence strongly suggests that the ground state of slightly distorted C2 B2Au4 is a covalent complex containing two B―Au―B three centers-two electrons (3c-2e) bonds. Unexpectedly, C3v Al+(AlAu4)-and C3v Al+(BAu4)-are predicted to have a salt-like composition with three X―Au―Al 3c-2e bonds (X=Al in Al2Au4, X=B in BAlAu4). Al2Au4 and BAlAu4 represent the first examples of bridging gold bonds in ionic-deficient systems. The adiabatic and vertical detachment energies of the anions were calculated to facilitate their future experimental characterization. Bridging gold addressed in this work provides an interesting bonding mode for covalent and ionic-deficient systems, and may aid in designing new materials and catalysts with highly dispersed Au atoms.%Au/H相似性的研究是现代化学中的一个热门话题.我们从理论上报道Au/H相似的新成员:共价化合物B2Au4,离子化合物Al2Au4和BAlAu4.采用密度泛函和波函数理论方法对比研究了缺电子体系B2Au4、Al2Au4和BAlAu4的几何和电子结构.详细讨论了它们基态结构的轨道、适应性自然密度划分(AdNDP)和电子局域函数(ELF)分析.计算结果表明稍微扭曲变形的C2 B2Au4是基态结构,在这个共价化合物中含有两个B―Au―B三中心二电子(3c-2e)键.然而C3v Al+(AlAu4)-和C3v Al+(BAu4)-被研究证明是含有三个X―Au―Al三中心二电子键的类盐化合物(在Al2Au4中X=Al, BAlAu4中X=B).

His doctrine, mainly with regard to the morbus lateralis, supports the proper one from the most of the sixteenth century authors belonging to the medical humanism: a copious bloodletting in the elbow`s flexure of the homolateral arm. In addition to the Vesalius’ anatomical contributions on the venous tree recorded in that chapter, Vega has a debate on certain controversial aspects with the contemporary doctors Argenterio and Fuchs. In spite of his fidelity to the galenism, Vega shows some practical disagreements concerning its use in children, pregnant women and its achievement up to fainting.

    We sought to identify cells and cytokines in bronchoalveolar lavage (BAL) fluids that distinguish asthma from healthy control subjects and those that distinguish controlled asthma from uncontrolled asthma. Following informed consent, 36 human subjects were recruited for this study. These included 11 healthy control subjects, 15 subjects with controlled asthma with FEV1≥80% predicted and 10 subjects with uncontrolled asthma with FEV1 cytokines were measured in these fluids. Compared to healthy control subjects, patients with asthma had significantly more percentages of eosinophils and neutrophils, IL-1RA, IL-1α, IL-1β, IL-2Rα, IL-5, IL-6, IL-7, IL-8, G-CSF, GROα (CXCL1), MIP-1β (CCL4), MIG (CXCL9), RANTES (CCL5) and TRAIL in their BAL fluids. The only inflammatory markers that distinguished controlled asthma from uncontrolled asthma were neutrophil percentage and IL-8 levels, and both were inversely correlated with FEV1. We examined whether grouping asthma subjects on the basis of BAL eosinophil % or neutrophil % could identify specific cytokine profiles. The only differences between neutrophil-normal asthma (neutrophil≤2.4%) and neutrophil-high asthma (neutrophils%>2.4%) were a higher BAL fluid IL-8 levels, and a lower FEV1 in the latter group. By contrast, compared to eosinophil-normal asthma (eosinophils≤0.3%), eosinophil-high asthma (eosinophils>0.3%) had higher levels of IL-5, IL-13, IL-16, and PDGF-bb, but same neutrophil percentage, IL-8, and FEV1. Our results identify neutrophils and IL-8 are the only inflammatory components in BAL fluids that distinguish controlled asthma from uncontrolled asthma, and both correlate inversely with FEV1.

  13. Source parameters of the 2005-2008 Balâ-Sırapınar (central Turkey) earthquakes: Implications for the internal deformation of the Anatolian plate

    Active tectonics of central Anatolia is mainly governed by the collision of the African, Arabian and Anatolian plates, which causes westward escape of Anatolia along the North and East Anatolian Fault zones, and the counterclockwise rotation of the Kırşehir block with insignificant internal deformation. The formation of the present-day tectonic processes in this region can be deduced from geophysical prospecting and seismological data. Although the seismicity in central Anatolia is distinctively lower than that in the northern and eastern parts of the Anatolian plate, small and moderate earthquakes (2.5 ≤ Mw ≤ 6.0) mostly occurred in the region in the past decades or so. For example, intense earthquake activity was observed in the Balâ-Afşar-Sırapınar (Ankara, central Anatolia) region in the period of 2005 to 2008 with destructive earthquakes of July 30, 2005 (Mw = 5.2); December 20, 2007 (Mw = 5.7) and December 26, 2007 (Mw = 5.6). Therefore, these earthquakes are crucial to analyze the shallow crustal deformation in the central Anatolian block. In the present study, we obtained source parameters of 2005-2008 earthquake sequence using the regional moment tensor (RMT) inversion method. We analyzed complete broad-band waveforms recorded at near-field distances (0.45° ≤ Δ ≤ 3.6°). Our results reveal NW-SE directed right-lateral strike-slip faulting and NE-SW directed left-lateral strike-slip faulting mechanisms, which are clearly correlated with the conjugate fault systems in the Balâ-Afşar-Sırapınar region. However, some earthquakes also have E-W directed normal faulting components. We suggest that the major characteristics of 2005-2006 and 2007-2008 earthquake activity could have been dominantly associated with left-lateral and right-lateral strike-slip faulting mechanisms, respectively. The seismogenic depth is found to be about 8-10 km. This result implies that earthquakes in the study region occurred mostly in the upper crust, which

In the ruin motif many different literary traditions (Baroque, Romantic, Postmodernist coincide, establishing a dialog with the corpus of the twentieth century. On the other hand, crystals as a heuristic model refer to Gilles Deleuze’s esthetics. Firstly, the analysis will provide the bases of a «syntax of the imaginary» in Nuñez’s poetry, accounting for the logic that rules the relations among images gathered around both nuclear metaphors (Burgos 1982. Secondly, it will trace the «anthropologic journey» of ruins and crystals as dynamic images that arise from the poem and reach subjective and social imaginaries (Durand 1960, 1993.

    The study of high-redshift bright quasars is crucial to gather information about the history of galaxy assembly and evolution. Variability analyses can provide useful data on the physics of the quasar processes and their relation with the host galaxy. In this study, we aim at measuring the black hole mass of the bright lensed BAL QSO APM 08279+5255 at $z=3.911$ through reverberation mapping, and at updating and extending the monitoring of its C IV absorption line variability. Thanks to 138 R-band photometric data and 30 spectra available over 16 years of observations, we perform the first reverberation mapping of the Si IV and C IV emission lines for a high-luminosity quasar at high redshift. We also cross-correlate the C IV absorption equivalent width variations with the continuum light curve, in order to estimate the recombination time lags of the various absorbers and infer the physical conditions of the ionised gas. We find a reverberation-mapping time lag of $\\sim 900$ rest-frame days for both Si IV and ...

    Full Text Available Since Eugenio María de Hostos’ publication in 1863 of La peregrinación de Bayoán until 1892, Columbus occupies a central space in his writings. The transformation of Columbus from a Romantic to a Positivist hero serves to exhibit the ideological, historical and political tensions of a colonial Puerto Rican subject questioning his historical and political legacy. It also triggers the examination not only of the figure of Columbus, Spain and the conquest, but of the Nineteenth century complex reality of the American, Caribbean and Latin American nation states.Desde la publicación de La peregrinación de Bayoán (1863 hasta el 1892 la escritura de Eugenio María de Hostos evidencia un especial interés por la figura de Cristóbal Colón. La centralidad del Descubridor, así como su transformación de genio romántico a positivista en el discurso hostosiano pone de relieve las tensiones históricas, políticas e ideológicas de un sujeto puertorriqueño colonial con respecto a su legado histórico-político. Sirve para cuestionar no solo la figura del mismo Colón, sino la conquista, y la situación de los pueblos de las dos Américas en el siglo diecinueve.

    We report the results of a new 60 ks Chandra X-ray Observatory Advanced CCD Imaging Spectrometer S-array (ACIS-S) observation of the reddened, radio-selected, highly polarized `FeLoBAL' quasar FIRST J1556+3517. We investigated a number of models of varied sophistication to fit the 531-photon spectrum. These models ranged from simple power laws to power laws absorbed by hydrogen gas in differing ionization states and degrees of partial covering. Preferred fits indicate that the intrinsic X-ray flux is consistent with that expected for quasars of similarly high luminosity, i.e., an intrinsic, dereddened and unabsorbed optical to X-ray spectral index of -1.7. We cannot tightly constrain the intrinsic X-ray power-law slope, but find indications that it is flat (photon index Gamma = 1.7 or flatter at a >99% confidence for a neutral hydrogen absorber model). Absorption is present, with a column density a few times 10^23 cm^-2, with both partially ionized models and partially covering neutral hydrogen models providi...

    We show for the first time that FBQS J1151+3822 is an iron low-ionization broad absorption line quasar (FeLoBAL QSO), the second-brightest and second-closest known example of this class. He I* and Fe II together act as an effective analytical tool, allowing us to obtain useful kinematic constraints from photoionization models of the outflow without needing to assume any particular acceleration model. The main outflow's log ionization parameter is -1.5, the log hydrogen density [cm^(-3)] 5.5 to 8, the log hydrogen column density [cm^(-2)] 21.7 to 21.9, the absorption radius 7.2 to 127 pc, and the kinetic luminosity 0.16 to 4.5% of the bolometric luminosity. We obtain line-of-sight covering fractions of ~0.25 for strong Fe II, ~0.5 for He I*, and ~0.6 for Mg II. Narrower and shallower absorption lines from weaker Fe II and Mn II with outflow velocity ~3400 km/s have appeared between 2005 and 2011, suggesting that dense cores may have condensed inside the main outflow. Consideration of the literature might sugge...

In the method, the composite material was taken as B matrix into which Al fibers were embedded in different configurations. The laminated B-Al material in the form of rectangular plates was subjected to lateral compressive loading. It is observed that stiffeners have significant effect on the buckling behavior of plates under compressive loading and for various geometrical configurations. The stiffeners used in the modeling are one-sided and have rectangular cross-sections. It is found that there are physically important loading intervals and the critical buckling modes make transitions back and forth between stable and unstable states. Bifurcation buckling regions resulting from various configurations of fiber orientations and different plate aspect ratios are determined. The whole analysis is performed by using ANSYS finite element computations. Only the buckling patterns of stiffened

    Full Text Available Hyperresponsiveness of the airways to nonspecific stimuli is a characteristic feature of asthma. Airway responsiveness is usually characterized in terms of the position and shape of the dose–response curve to methacholine (MDR. In the study we have investigated the influence of fluticasone propionate (FP, a topically active glucocorticoid, on arachidonic acid (AA metabolites in broncho-alveolar lavage (BAL fluid (i.e. TxB2, PGE2, PGD2, 6kPGF1α and LTC4 on the one hand and MDR curves on the other hand. The effect of FP was studied in a randomized, double-blind, placebo-controlled design in 33 stable nonsmoking asthmatics; 16 patients received FP (500 μg b.i.d. whereas 17 patients were treated with placebo. We found that the forced expiratory volume in 1s (FEV1 % predicted increased, the log2PC20 methacholine increased and the plateau value (% fall in FEV1 decreased after a 12 week treatment period. No changes in AA-metabolites could be determined after treatment except for PGD2 which decreased nearly significantly (p = 0.058 within the FP treated group, whereas the change of PGD2 differed significantly (p = 0.05 in the FP treated group from placebo. The levels of the other AA metabolites (i.e. TxB2, PGE2, 6kPGF1α and LTC4 remained unchanged after treatment and were not significantly different from the placebo group. Our results support the hypothesis that although FP strongly influences the position, the shape and also the maximum response plateau of the MDR curve, this effect is not mainly achieved by influence on the level of AA metabolites. Other pro-inflammatory factors may be of more importance for the shape of the MDR curve. It is suggested that these pro-inflammatory factors are downregulated by FP.

    Precision glass molding (PGM) is an optical manufacturing process used to hot press optical glass into a specified lens shape. This is done by taking the glass to a temperature above Tg and exerting force using an upper and lower mold. These molds will, together, give the pressed lens its shape. This study focuses on the high temperature interactions between the mold tooling material and two optical oxide glasses, Ohara's L-BAL35 and Schott's N-FK5. Flat molds were used to press flat glass work pieces at high temperature and force; key post process parameters such as sample and mold surface contamination using EDS and visible degradation via SEM were catalogued and analyzed. The molds used were bare tungsten carbide (WC) and silicon carbide (SiC) with an amorphous SiC chemical vapor deposition (CVD) coating. The results showed that raw WC molds suffered the most degradation including physical damage as well as chemical adherence and reaction. The Ti binder used in the WC as well as some the tungsten itself transferred to both glasses and caused a white reflective layer to appear on the molded glass surface. Severe damage was evident after only 2 pressing cycles with potassium from N-FK5 being the most prominent chemical contaminant. N-FK5 proved to be the more corrosive of the two glasses in all occasions. The SiC coated molds fared better in terms of degradation than the WC, however sticking of glass to mold was a problem.

    Full Text Available After decades of seclusion in the shadow of its promotion, Aníbal Núñez’s poetry is starting a recovery process in recent critical studies. After overcoming the restrictive premises used by poetry criticism to reduce the authors´ list and poetical tendencies of 68, the isolation of those poets —whose works did not fit in the dominant canon— is object of review in current historiography of Spanish contemporary poetry. This return to the once-excluded poets is essential to understand the plurality of discourses which make up the generation of 68: it is necessary to revive their voices of discord in order to outline their whole aesthetic scene. In the light of the innovative theoretic-critical paradigm of Spanish postmodern poetry, the works by Aníbal Núñez may be fully part of the creative scene of his generation, without forgetting the peculiarities which distinguish his poetic writing.Tras décadas de reclusión en la zona umbrosa de su promoción, la poesía de Aníbal Núñez está iniciando un proceso de recuperación en los estudios críticos recientes. Superadas ya las restrictivas premisas con que la crítica redujo la nómina de autores y tendencias poéticas del 68, el aislamiento de los poetas cuya obra no encajaba en el canon hegemónico es objeto de revisión en la actual historiografía de la poesía española contemporánea. Esta restitución de los excluidos es esencial para entender la pluralidad de los discursos que componen la generación del 68: recuperar sus voces discordantes es necesario para trazar su escenario estético completo. A la luz del innovador paradigma teórico-crítico de la poética posmoderna española, los libros de Aníbal Núñez pueden insertarse plenamente en el panorama creador de su generación, sin menoscabo de las peculiaridades que singularizan su escritura poética.

    Full Text Available Os materiais compósitos de matriz polimérica (PMCs reforçados por fibras são considerados excelentes materiais de engenharia. Em aplicações estruturais, quando uma elevada relação resistência peso é fundamental para o projeto, os PMCs vêm substituindo com sucesso diversos materiais convencionais. Materiais têxteis são utilizados, desde a 2ª Guerra Mundial, como blindagens balísticas. Materiais fabricados com fibra do polietileno de altíssimo peso molecular (UHMWPE são empregados na produção de blindagens, para proteção pessoal e em carros de combate. Todavia, em virtude de terem sido desenvolvidos e comercializados mais recentemente, não existem informações suficientes sobre o desempenho balístico desses materiais após a sua exposição aos agentes ambientais. No presente trabalho foi estudado o comportamento balístico de placas compósitas fabricadas com fibra de polietileno de altíssimo peso molecular (UHMWPE, após sua exposição à radiação gama. Os resultados dos testes balísticos foram relacionados com as alterações macromoleculares induzidas pela irradiação por meio de ensaios mecânicos (dureza, impacto e flexão e físico-químicos (espectroscopia no infravermelho, calorimetria diferencial de varredura e análise termogravimétrica. Foi verificado que a irradiação gama provoca modificações nas cadeias macromoleculares do polímero, que alteram as propriedades mecânicas do compósito de UHMWPE, reduzindo, nas doses de radiação mais elevadas, o seu desempenho balístico.

No primeiro experimento, cartelas com ovos de Spodoptera frugiperda, 1797 foram mergulhadas em suspensões preparadas com os produtos e, em seguida, colocadas à disposição dos parasitóides para oviposição, durante um período de 24 horas. No segundo, fêmeas do parasitóide foram alimentadas com uma solução mel e suspensão de conídios. Em ambos os experimentos as fêmeas mortas foram colocadas em uma câmara úmida para observar a esporulação dos fungos. Os tratamentos foram mantidos em câmara climatizada com temperatura de 25±1º C, umidade relativa de 70±10% e fotofase de 14 horas. Avaliou-se a longevidade e mortalidade dos adultos, índice de parasitismo, emergência do parasitóide, número de indivíduos por ovo e razão sexual dos descendentes. As formulações não interferiram nos parâmetros avaliados e não foi observada a esporulação do fungo no cadáver do parasitóide adulto.

Algunos de estos textos fueron publicados en la prensa chilena y estadounidense, y el resto en forma de libro. Entre sus autores se hallan Rodolfo Lenz, Miguel Luis Amunátegui Reyes y Fidelis del Solar, quienes desempeñaron papeles importantes en el desarrollo de la lingüística en Chile. Concluimos que la recepción de la obra de Echeverría fue mayormente negativa porque los comentaristas la interpretaron como una obra prescriptiva que adolecía de defectos fundamentales para cumplir con su propósito normativo, interpretación congruente con el periodo de la lexicografía y la lingüística chilena en que se enmarca, llamado precientífico por Matus (1994 y caracterizado por un marcado interés normativista. Entre las críticas más abundantes sobresale el desacuerdo sobre el tratamiento normativo dado a ítems particulares, lo cual interpretamos en términos de una negociación de normas connatural a una comunidad lingüística que atraviesa un proceso de estandarización, como era el Chile hispanohablante de fines del siglo xrx.This paper analyzes how Voces usadas en Chile, a lexicographical work written by Chilean lawyer and amateur linguist Aníbal Echeverría y Reyes and published in 1900, was received by his contemporaries, as it can be seen in a corpus of six critical texts dated between 1899 and 1905.

    Full Text Available Inhabitants of urban and rural areas are important participants in the process of developing and implementing forest policy. Thus, it is essential to determine their demands and attitudes towards forestry issues. In this context, the demands and evaluation of forest functions are investigated in a case study of the Turkish province of Bal kesir. The findings of the case study show that differences in terms of demands among inhabitants of rural and urban areas are related to forest fires fighting, crimes fighting, forestry-tourism integration, forestation and regeneration activities, and the enlargement of forest areas. The main differences among their assessments of forest functions are related to fire wood production, and the provision of flood and erosion control, nature protection, and recreational opportunities. The findings are important for conflict management and for local decision making. By using the findings of similar studies, the provincial organizations should harmonize their priorities with the expectations of relevant interest groups.A política de silvicultura da população urbana e rural é uma participante fundamental no processo de formação e execução das florestas.

    Full Text Available The San Cristóbal pluton is a 35 km2 granitic body that outcrops at the southestern tip of the Sierra de Velasco, located west of La Rioja city, Argentina. It is formed by monzogranites and syenogranites, together with scarce granodiorites, with medium to fine-grained, equigranular to slightly porphyritic textures. Their mineral assemblage consists of quartz + microcline + plagioclase + biotite ± muscovite + zircon + apatite + magnetite. The granite contains dioritic to tonalitic mafic enclaves. The central and eastern parts of the granite have been deformed by the NNW-SSE trending South Mylonitic shear zone formed by mylonitic rocks. The metamorphic host-rock is represented by scarce greenschist facies xenoliths and hornfels with the high T / P assemblage K-feldspar - cordierite - biotite ± sillimanite. The granites are calc-alkaline, weak- to moderately peraluminous, and formed as part of a continental magmatic arc developed along the active margin of western Gondwana during the Early Paleozoic. The depth of emplacement of the San Cristóbal pluton is estimated at ~12 km.

    Full Text Available El estudio analiza la organización comunitaria en la gestión del agua para consumo humano y uso doméstico y el papel que juegan las mujeres en ella en las localidades urbanas y rurales de las subcuencas Río Sabinal y Cañón del Sumidero en Berriozábal, Chiapas. El agua es suficiente, pero en la época de sequía disminuye y no alcanza para cubrir los requerimientos de quienes se benefician de estas fuentes. Por ello, las mujeres tienen que asumir la responsabilidad de abastecer el agua que se utiliza en el hogar, lo que les genera más carga de trabajo.

    The lattice parameters, band structure, density of states, effective mass, carrier concentration and electrical resistivity of 3C-SiC in different doped forms (undoped, B-doped, Al-doped and B-Al co-doped) are calculated using the plane wave ultrasoft pseudopotential based on density functional theory. Calculations indicate that as the B or Al replaces Si atoms, both the conduction band and valence band shift to higher energy level. The top of valence band shifts quicker, resulting in the decrease of the band gap. B-Al co-doped 3C-SiC shows the narrowest bandgap while the pure one has the widest. Effective mass of B-doped 3C-SiC decreases but that of Al-doped 3C-SiC increases;while B-Al co-doped 3C-SiC effective mass, whose value approaches to the undoped, can be understood in terms of different compensation. As the acceptor impurities, B and Al will greatly increase the carrier density of valence band top, and the carrier density of the co-doped is three times as Large as the B-doped or Al-doped 3C-SiC. In addition, B-Al co-doping has the lowest resistivity among the four doping forms displaying its significant advantages in electrical property.%采用基于密度泛函理论的第一性原理平面波超软赝势法,计算了未掺杂, B, Al单掺杂和B-Al共掺杂的3C-SiC的晶格参数、能带结构、态密度、有效质量、载流子浓度和电阻率.计算结果表明:掺杂后导带和价带都向高能端移动,价带移动速度更快一些,使得禁带宽度都有一定程度的减小,其中B-Al共掺杂的禁带宽度最窄,纯净3C-SiC的禁带宽度最宽;B掺杂会减小价带顶空穴的有效质量, Al掺杂则反之, B-Al共掺杂补偿了二者的差异,和未掺杂的3C-SiC价带顶空穴的有效质量很接近. B和Al作为受主杂质,会极大地提高价带顶空穴载流子的浓度,而且B-Al共掺杂的3C-SiC的价带空穴浓度是B, Al单掺杂时的3倍.4种体系中, B-Al共掺杂得到的电阻率是最低的,同单掺杂

    Full Text Available Alzheimer's disease (AD is characterized by progressive dysfunction of memory and higher cognitive functions with abnormal accumulation of extracellular amyloid plaques and intracellular neurofibrillary tangles throughout cortical and limbic brain regions. Withania somnifera (WS also known as 'ashwagandha' (ASH is used widely in Ayurvedic medicine as a nerve tonic and memory enhancer. However, there is paucity of data on potential neuroprotective effects of ASH against β-Amyloid (1-42 (Aβ induced neuropathogenesis. In the present study, we have tested the neuroprotective effects of Methanol: Chloroform (3:1 extract of ASH and its constituent Withanolide A (WA against Aβ induced toxicity, HIV-1(Ba-L (clade B infection and the effects of drugs of abuse using a human neuronal SK-N-MC cell line. Aβ when tested individually, induced cytotoxic effects in SK-N-MC cells as shown by increased trypan blue stained cells. However, when ASH was added to Aβ treated cells the toxic effects were neutralized. This observation was supported by cellular localization of Aβ, MTT formazan exocytosis, and the levels of acetylcholinesterase activity, confirming the chemopreventive or protective effects of ASH against Aβ induced toxicity. Further, the levels of MAP2 were significantly increased in cells infected with HIV-1(Ba-L (clade B as well as in cells treated with Cocaine (COC and Methamphetamine (METH compared with control cells. In ASH treated cells the MAP2 levels were significantly less compared to controls. Similar results were observed in combination experiments. Also, WA, a purified constituent of ASH, showed same pattern using MTT assay as a parameter. These results suggests that neuroprotective properties of ASH observed in the present study may provide some explanation for the ethnopharmacological uses of ASH in traditional medicine for cognitive and other HIV associated neurodegenerative disorders and further ASH could be a potential novel drug to

    Full Text Available Although the image of America in the Spanish literature of the Golden Age has not been analyzed very often by the hispanists, it is remarkable that the character of the indiano —the Spaniard that emigrated to the Indias— is condemned by a prose writer from Valladolid, Dr. Cristóbal Suárez de Figueroa, in his fictional work El pasajero, dated in 1617. In that narrative, Suárez strongly disapproves colonization and, without openly defending aborigines, attacks the indianos on the grounds of their greed, ignorance, and double-dealing. In this study, Suárez’s denounce is compared to other contemporaries’ more moderate views.

    Aunque la imagen de América en la literatura española del Siglo de Oro no ha sido todavía analizada con demasiado detenimiento por los hispanistas, hay que destacar que el personaje del indiano —el emigrante español en las Indias Occidentales— es condenado por un escritor en prosa de Valladolid, el doctor Cristóbal Suárez de Figueroa, en su obra de ficción El pasajero, de 1617. En ese relato, Suárez desaprueba la colonización y, sin defender abiertamente a los indígenas, ataca a los indianos por su codicia, ignorancia y doblez. En este estudio, la denuncia de ese autor es contrastada con otras visiones de sus contemporáneos, en general más matizadas.

    Full Text Available La sucesión generacional en una empresa es un proceso dinámico en que los papeles y tareas del predecesor y del sucesor evolucionan de manera independiente y en paralelo, hasta que se cruzan y se superponen, encaminando la empresa a la sustentabilidad. El presente documento reflexiona sobre la relación entre sucesión generacional y sustentabilidad en dichas empresas, analizando una muestra de conveniencia de nueve empresas familiares restauranteras en San Cristóbal de las Casas (Chiapas, México, y realizando un comparativo cualitativo a partir de los indicadores de las variables de estudio. Adicionalmente, se examina la situación de las empresas familiares en México y su relevancia e importancia para la economía. Se encontró que la importancia de la empresa familiar, tanto a nivel nacional como local, y el amplio desarrollo de la actividad restaurantera en San Cristóbal de las Casas, motivan a las familias dedicadas a esta actividad a continuar sus negocios y a transmitirlos a las futuras generaciones para ser sustentables, ya que, de acuerdo con lo que reporta el Instituto Nacional de Estadística y Geografía (INEGI, nueve de diez empresas familiares que se crean no llegan a los dos años de vida, lo cual constituye un índice de mortalidad extremo.         La unión familiar al interior de la empresa es el vínculo ideal para la sustentabilidad de la misma, ya que de ella depende una exitosa sucesión generacional que propicie que la empresa familiar perdure en sus actividades.

    Full Text Available Background and aims: large balloon sphincteroplasty (LBS associated with sphincterotomy (ES has gained acceptance as a useful tool in extracting difficult bile duct stones. Our purpose was to evaluate the efficacy and safety of LBS with balloons ≥ 10 mm in clinical practice setting. Patients and methods: unicentre prospective study in a tertiary care hospital. All patients who underwent LBS associated with ES between July 2007 and March 2011 were included prospectively in a database recording clinical aspects, procedure data, outcome and complications. Success is the main outcome defined as complete stone removal documented by absence of any filling defect during a final occlusion cholangiogram and absence of clinical or radiological findings after the ERCP consistent with remaining stones. Complications as pancreatitis, cholangitis, post-ERCP bleeding, perforation and others were also measured. Results: one hundred twenty procedures were made in 109 patients with balloons ranging from 10 to 20 mm. Success rate was 91% in the first attempt and 96.7% after two procedures. Mechanical lithotripsy was only needed in one case (0.8%. Complication rate was 4.2% due to five cases of post-ERCP bleeding in high risk patients. Conclusion: large balloon sphincteroplasty associated to sphincterotomy in clinical practice is a very effective and safe technique.Introducción y objetivos: la dilatación con balón de gran tamaño asociada a esfinterotomía es un recurso cada vez más utilizado en la extracción de coledocolitiasis de gran tamaño.

    Full Text Available Los parámetros geotécnicos de los suelos (número de golpes del ensayo de penetración estándar, densidad natural, contenido de finos, límite líquido, humedad y el índice de plasticidad intervienen en las ecuaciones empíricas para determinar la variación de la intensidad sísmica, la velocidad de ondas transversales, la susceptibilidad a la licuefacción, entre otros. Generalmente, se emplean valores promedios que caracterizan la formación geológica, o un complejo ingeniero geológico, lo que induce una gran incertidumbre. Este artículo propone un procedimiento para la estimación y modelación de los principales parámetros geotécnicos que inciden en la zonación sísmica local. El procedimiento consta de cuatro etapas: la elaboración de bases de datos, el análisis exploratorio de datos, la creación del modelo geológico 3D y, finalmente, la generación del modelo cuantitativo. La aplicación de esta metodología en la ciudad de San Cristóbal reveló valores bajos de densidad natural, lo que sugiere condiciones desfavorables de respuestas de los suelos frente a sismos

    Full Text Available FUNDAMENTO: Tempo porta-balão adequado (BACKGROUND: An adequate door-to-balloon time (<120 minutes is the necessary condition for the efficacy of primary angioplasty in infarction to translate into effectiveness. OBJECTIVE: To describe the effectiveness of a quality of care protocol in reducing the door-to-balloon time. METHODS: Between May 2010 and August 2012, all individuals undergoing primary angioplasty in our hospital were analyzed. The door time was electronically recorded at the moment the patient took a number to be evaluated in the emergency room, which occurred prior to filling the check-in forms and to the triage. The balloon time was defined as the beginning of artery opening (introduction of the first device. The first 5 months of monitoring corresponded to the period of pre-implementation of the protocol. The protocol comprised the definition of a flowchart of actions from patient arrival at the hospital, the team's awareness raising in relation to the prioritization of time, and provision of a periodic feedback on the results and possible inadequacies. RESULTS: A total of 50 individuals were assessed. They were divided into five groups of 10 sequential patients (one group pre- and four groups post-protocol. The door-to-balloon time regarding the 10 cases recorded before protocol implementation was 200 ± 77 minutes. After protocol implementation, there was a progressive reduction of the door-to-balloon time to 142±78 minutes in the first 10 patients, then to 150±50 minutes, 131±37 minutes and, finally, 116±29 minutes in the three sequential groups of 10 patients, respectively. Linear regression between sequential patients and the door-to-balloon time (r = - 0.41 showed a regression coefficient of - 1.74 minutes. CONCLUSION: The protocol implementation proved effective in the reduction of the door-to-balloon time.

    The Miocene volcanic rocks along the İzmir-Balıkesir Transfer Zone along the western margin of the Menderes Core Complex (MCC) in western Anatolian Volcanic Province (WAVP), where strike-slip deformation is dominant, comprise: (Group 1) early-middle Miocene high-K to shoshonitic rocks with high-Mg# and relatively low SiO2, (Group 2) middle Miocene phonolitic rocks with low-Mg# and intermediate SiO2, (Group 3) early-middle Miocene medium- to high-K series from andesites to rhyolites, (Group 4) middle Miocene rhyolites with distinct trace element compositions; and (Group 5) late Miocene high-MgO basalts, K-trachybasalts and (Group 6) late Miocene high-MgO basaltic andesites. The geochemical features of these rocks are comparable with the other Oligocene to Miocene volcanic rocks, but differ from the Eocene volcanic rocks in WAVP. The geochemical features of the most primitive early-middle Miocene Group 1 rocks indicate that they were derived from an anomalously metasomatized lithospheric mantle. The mineralogical and geochemical properties of garnet-amphibole peridotite from the Ulten Zone (UZP), Eastern Alps, which is thought to represent a fossil metasomatic mantle wedge contaminated by continental subduction, is similar to the model mantle composition previously proposed for the genesis of the mafic rocks. Together with the presence of Eocene to early Miocene continental subduction beneath the Aegean-west Anatolia region, this strongly suggests that continental subduction was an important factor in the genesis of the high-MgO shoshonitic to ultrapotassic volcanism in this post-collisional area. The origin of the Group 3 andesitic to rhyolitic rocks includes; (1) lower crustal melting, (2) mixing between lower crustally-derived and mantle-derived melts, and (3) FC-AFC processes. The late Miocene Group 5 and 6 rocks, however, derived from a more depleted mantle source, indicating that the mantle became depleted over time. The rhyolites of Group 4 are most probably

This place decorated with colorful mosaics and wall paintings also having a good handcrafted floor is dated back to Roman Empire period. Besides Dionysos, Ariadne, Meinad, and Eros holding a wineglass figures related with Dionysos cult on the mosaic; theatre masks, fish and bird figures all together demonstrate that it could be used as a banquet hall for official invitations during theatre plays.  These fish and bird figures have great importance to analyze the nutrition habits of antique cities, especially metropolis, which has few materials that could be read. The various fish and bird figures on the reception hall were examined by expert zoologists to try to identify the factors such as, this fish and birds’ species, their habitats and if they were eatable or not. The paper also tries to find out the nutrition habits of Metropolis community using the found data from ancient sources and obtained from this research.

    Full Text Available O tratamento da síndrome de baixo débito cardíaco tem evoluído muito, em especial em relação aos dispositivos mecânicos de assistência ventricular. Esses dispositivos podem genericamente ser agrupados em pulsáteis e não pulsáteis. Existe grande polêmica sobre as vantagens e desvantagens de cada um desses grupos de dispositivos. O objetivo deste trabalho é avaliar a ação da bomba centrífuga sobre o fluxo coronário e carotídeo na assistência circulatória do ventrículo esquerdo em cães com coração normal. Além disso, verificamos se o uso concomitante do balão intra-aórtico é suficiente para contrabalançar os possíveis efeitos deletérios da assistência circulatória com fluxo contínuo. Foram estudados 15 cães, com peso corpóreo médio de 16,3 kg. Realizamos a avaliação hemodinâmica dos animais, através da medida seriada das pressões do átrio direito, do capilar pulmonar, das artérias pulmonares, da circulação arterial sistêmica e a freqüência cardíaca. Foi realizada a aferição do débito cardíaco e calculados os seguintes parâmetros hemodinâmicos derivados: índice cardíaco, índice sistólico, resistência vascular sistêmica e resistência vascular pulmonar. O fluxo sangüíneo carotídeo e coronariano foram obtidos com o uso de transdutores eletromagnéticos. Os parâmetros foram analisados em quatro situações: S1. situação controle; S2. situação de teste da bomba centrífuga em que esse dispositivo realiza a assistência circulatória do ventrículo esquerdo; S3. situação de teste da bomba centrífuga e do balão intra-aórtico; S4. situação final em que é feita a contraprova desligando-se o balão intra-aórtico. A avaliação hemodinâmica através dos diversos parâmetros não mostrou alteração estatisticamente significante nas quatro situações. Já em relação ao fluxo coronário a utilização da assistência circulatória isolada com bomba centrífuga (S2 e S4 diminuiu

    Full Text Available OBJETIVO: Apresentar os resultados dos exames de manometria anorretal realizados com um aparelho brasileiro computadorizado, que utiliza o método do balão para a caracterização do reflexo inibitório reto anal na investigação diagnóstica da doença de Hirschsprung, em crianças com constipação crônica. MÉTODOS: Foram analisados os resultados de 372 manometrias anorretais realizadas consecutivamente em pacientes com constipação crônica. O equipamento utilizado (Proctosystem-Viotti possui dois canais utilizados para registar as pressões do esfíncter anal e da ampola retal por meio de balões conectados por sonda aos transdutores de pressão. Os valores pressóricos são avaliados em computador utilizando software específico. A ausência do reflexo inibitório reto-anal foi considerada como sugestiva de doença de Hirschsprung, sendo o diagnóstico confirmado pelos métodos tradicionais. RESULTADOS: Em 14 (3,8% dos 372 exames não foi caracterizado o reflexo inibitório reto-anal. Em nove destes 14 pacientes o diagnóstico de doença de Hirschsprung foi confirmado pela caracterização de ausência de células ganglionares na avaliação anatomopatológica. Nos outros cinco pacientes não foi realizada a biópsia retal em função da evolução clínica satisfatória com o tratamento clínico da constipação, sendo que em quatro a presença de reflexo inibitório reto-anal foi caracterizada por exame de manometria anorretal realizado posteriormente. CONCLUSÃO: O equipamento utilizado foi apropriado para a realização da manometria anorretal permitindo descartar o diagnóstico de doença de Hirschsprung em 86,5% dos pacientes. Foi identificado um pequeno grupo de pacientes nos quais, em mais da metade, o diagnóstico definitivo de doença de Hirschsprung foi estabelecido.OBJECTIVE: to evaluate results of anorectal manometry performed with equipment made in Brazil for the screening of Hirschsprung's disease in children with

    Full Text Available OBJETIVO: A troca valvar aórtica é procedimento rotineiro, envolve substituição da valva nativa/prótese. Na maioria destes pacientes o risco é aceitável, porém, em alguns casos, o risco predito pode justificar contra-indicação. O implante de valva aórtica minimamente invasivo transcateter e sem circulação extracorpórea (CEC tem se mostrado viável, com menor morbi-mortalidade. O objetivo deste trabalho foi desenvolver bioprótese aórtica, montada em cateter, para implante sem CEC. MÉTODOS: Após desenvolvimento em animais, três pacientes com EuroSCORE elevado foram submetidos ao implante. Caso 1: portador de bioprótese com disfunção; Caso 2: estenose aórtica grave; Caso 3: disfunção de bioprótese aórtica. Após minitoracotomia e sob controle ecocardiográfico e fluoroscópico, cateter-balão foi posicionado sobre posição aórtica e insuflado. Após, segundo cateter-balão, com endoprótese valvada, foi posicionado e liberado sob alta frequência ventricular. Controles angiográficos e ecocardiográficos foram realizados e pacientes encaminhados para UTI. RESULTADOS: No primeiro caso foi possível implante sem CEC com resultados adequados. Evoluiu com melhora da função ventricular. Cursou com broncopneumonia, fístula traqueo-esofágica e óbito por mediastinite. Necropsia confirmou bom posicionamento valvar e preservação dos folhetos. O segundo caso apresentou migração do dispositivo após insuflação do balão, necessidade de esternotomia mediana de urgência, CEC e troca valvar convencional. O paciente evoluiu bem, recebendo alta da UTI 14 dias após procedimento e sem complicações. Cursou com infecção respiratória, choque séptico e óbito no 60º pós-operatório. O terceiro caso foi submetido a implante com sucesso. CONCLUSÃO: O implante de bioprótese transapical montada em cateter sem CEC mostrou ser procedimento factível.

    Full Text Available INTRODUCTION: Two anorectal manometry techniques have commonly been utilized: the perfusion technique and the balloon technique. PURPOSE: To compare both techniques in children with intestinal constipation who had not undergone surgical treatment for its correction. METHODS: Thirty-nine children aged between four and fourteen years underwent anorectal manometry using both techniques at random. Resting pressure, pressure response to voluntary contraction, coughing and perianal stimulation, maximum pressure on the anal canal pressure curve, and presence of rectosphincteric reflex were registered and submitted to statistics. Vectorgraphy of the sphincter muscle complex was obtained by perfusion technique. RESULTS: The statistical comparison between the techniques revealed statistically significant differences in resting pressure (p=0.041, pressure response to voluntary contraction (p=0.026 and maximum pressure within the pressure curve (p=0.010. The rectosphincteric reflex was demonstrated in 21 patients by both techniques. CONCLUSIONS: The perfusion technique presented greater sensitivity in the following parameters: resting pressure, pressure response to voluntary contraction and maximum pressure within the pressure curve. The methods studied are equivalent regarding the measurement of pressure responses to coughing and perianal stimulation and the investigation of rectosphincteric reflex.INTRODUÇÃO: A manometria anorretal tem sido aceita como uma técnica objetiva de estudar a função do complexo muscular esfincteriano.

    Full Text Available Este artigo vem analisar, a partir de um estudo de caso comparativo entre o balé clássico e a dança contemporânea, como a dança se relaciona com a formação humana em uma sociedade capitalista hegemônica. Presenciamos na dança contemporânea formas muito ricas de trabalho, com uma grande abertura para o crescimento crítico e criativo do ser humano. Porém, estão presentes no grupo analisado algumas contradições no que se refere aos conteúdos e à metodologia utilizada para alcançar os objetivos. No balé clássico nos deparamos com a busca pela apropriação da técnica institucionalizada cujos significados e códigos refletem uma sociedade hierarquizada e autoritária. Sua proposta de trabalho é pautada na reprodução e repetição a fim de chegar a um movimento tecnicamente perfeito. Desvencilhar-se das antigas concepções reafirmadas pelo balé clássico sobre o ensino da dança é bastante árduo, porém muito necessário para que tenhamos uma nova proposta, pautada na liberdade e no respeito pela individualidade do ser humano. Acreditamos que também a possibilidade de criação, intervenção e questionamentos no espaço de ensino venha a ser fundamental para a formação de um ser humano que se entenda como sujeito de suas ações na sociedade em que está inserido. PALAVRAS-CHAVE: Dança - Formação humana - Balé clássico - Dança contemporânea. This article aims at analizing, from the starting point of a case study comparing Classic Ballet and Contemporary Dance, how dance can relate to human development, within the context of a capitalist-dominated society. We have observed that contemporary dance offers many enriching forms of work, with great openness for the perceptive and creative growth of a human being. The analyzed group, however, presented a few contradictions in regards to the contents and methodology that were used to achieve their goals.

    positivamente para a melhoria do fluxo faringoesofágico por diminuição da resistência local. A eficiência deste procedimento será dependente da existência de alguma força de ejeção e elevação hiolaríngea. O fascículo transverso do músculo cricofaríngeo é fitado, de pequena espessura, para ser infiltrado por via transcutânea com a toxina botulínica. Talvez por via endoscópica, à semelhança das miotomias, o indicado seria desnervar somente o fascículo transverso do músculo cricofaríngeo. Neste contexto dose, diluição e pontos de infiltração assumem importante papel no uso terapêutico desta neurotoxina em nível do cricofaríngeo. A dilatação por balão pneumático da transição faringoesofágica não parece ser procedimento adequado para região que não apresente estenose fibrótica a ser rompida. Em razão das características anatômicas da transição faringoesofágica, a pressão média de repouso, como registrada pelo método manométrico, não avalia adequadamente a ineficiência ou efetividade da miotomia, da desnervação ou do resultado da dilatação por balão pneumático.BACKGROUND: The cricopharyngeal muscle is of the skeletal type and, in this way, unable to sustain continuous contraction for long periods. Despite of this it has been considered as the responsible by the high pressure area, registered by manometry into the pharyngoesophageal transition. For this reason, it has been the object of therapeutics that promote the rupture of its integrity. AIMS: To give the anatomical bases to define the limits of participation of the cricopharyngeal muscle in the pharyngoesophageal transition function. To consider a morphological and functional alternative to explain the high pressure area on pharyngoesophageal transition and the implications of the myotomy, use of the botulinum toxin and balloon dilatation on pharyngoesophageal transition function.

    Full Text Available OBJETIVO: Determinar possíveis alterações do volume corrente e da pressão de pico inspiratório fornecidos por sete modelos de reanimador manual com balão auto-inflável em função do fluxo de entrada de oxigênio utilizado. MÉTODOS: Os reanimadores testados foram: Oxigel, modelos A e B; CE Reanimadores; ProtecSolutions; Missouri; Axmed; e Narcosul. Para as aferições, acoplaram-se um fluxômetro de oxigênio de parede, um fluxômetro/respirômetro, um reanimador, um sensor (aparelho Tracer 5 e um pulmão-teste. Além disso, acoplou-se o aparelho Tracer 5 a um notebook. Utilizaram-se fluxos de entrada de oxigênio de 1, 5, 10 e 15 L/min. RESULTADOS: O volume corrente fornecido pelo reanimador Oxigel modelo A ao receber 15 L/min de oxigênio foi aproximadamente 99% maior que o fornecido ao receber 1 L/min de oxigênio. Da mesma forma, a pressão de pico inspiratório foi 155% maior. Nas mesmas condições, o volume corrente fornecido pelo reanimador Narcosul foi 48% maior, e a pressão de pico inspiratório foi 105% maior. Os demais reanimadores testados não apresentaram alterações significativas do volume corrente e da pressão de pico inspiratório fornecidos. CONCLUSÕES: Nas condições de resistência e complacência utilizadas, os reanimadores em que o fluxo de entrada de oxigênio é direcionado diretamente ao interior do balão tiveram a válvula do paciente presa em posição de inspiração ao receberem um fluxo > 5 L/min, aumentando significativamente o volume corrente e a pressão de pico inspiratório fornecidos. Isso não ocorreu nos reanimadores em que o fluxo de entrada de oxigênio é direcionado ao exterior do balão.OBJECTIVE: To assess possible alterations in the tidal volume and peak inspiratory pressure delivered by seven models of manually operated self-inflating resuscitation bags as a function of the oxygen supply rate used.

An automated algorithm was used to match a continuum to each quasar and to identify regions of flux at least 10% below the continuum over a velocity range of at least 1000km/s in the CIV and MgII absorption regions. The model continuum was selected as the best-fit match from a set of template quasar spectra binned in luminosity, emission line width, and redshift, with the power-law spectral index and amount of dust reddening as additional free parameters. We characterize our sample through the traditional balnicity index and a revised absorption index, as well as through parameters such as the width, outflow velocity, fractional depth, and number of troughs.

    Full Text Available Viability of Beauveria bassiana is extremely low due to toxic compounds in soils. This research was aimed to study the effect of four groups of media on viability of B. bassiana Bb-Pb2. The first group was leaf litters of onion, flowering white cabbage, cabbage, and chinese mustard, respectively; the second group was the soils containing decomposed residues of each plant of the first group; the third group was the mixtures of each media of both groups above (1:1, and the fourth group was natural top soil as a control. Each plastic bag filled with one kg of each medium was inoculated with ten ml of B. bassiana conidia (106/ml of concentration and incubated in open area for 8 weeks. The results showed that all leaf litters of those plants and their compost soils affected the fungal viability. The highest decreasing number of colony was found on onion’s leaf litters, soil containing of decomposed onion, and the mixtures of both media. The treated B. bassiana showed significant reducing abilities of growth, conidia production and conidia germination on PDA media, except the one of control. It is suggested that the Bb-Pb2 isolate might not be effective as bioinsecticide in the soils containing either those leaf litters or composts.

    Full Text Available The cotton leafworm, Alabama argillacea (Huebner, 1818 (Lepidoptera: Noctuidae, is considered to be one of the key pests in herbaceous cotton (Gossypium hirsutum L. r. latifolium Hutch cropping, with constant occurrence in all cotton-growing states of Brazil. In this study Metarhizium anisopliae and Beauveria bassiana isolates were screened and evaluated for pathogenicity against Alabama argillaceae. Initially, a screening of ten isolates of each fungus in a concentracion of 10(8 conidia mL-1, was carried out on 3rd instar larvae of A. argillacea. Further studies were conducted to determine the pathogenicity and virulence of six and seven isolates of M. anisopliae and B. bassiana, respectively, against 3rd instar larvae of A. argillacea and using the concentrations of 10(6, 10(7, 10(8, and 10(9 conidia mL-1. The experiments were carried out in Recife, PE, Brazil, at 27 ± 2ºC, RH 70 ± 5% and a photophase of 12 hours. Mortalities caused by M. anisopliae isolate at the different concentrations ranged from 4.5 to 91.2%, the highest mortality percentage being found for the isolate 1189 at 10(9 conidia mL-1. The isolate 645 of B. bassiana caused the highest mortality at the highest concentration, followed by isolates 634, 604, and IPA 198. The lowest lethal time for B. bassiana and M. anisopliae, was achieved by the isolates 483 (4.1 days and 1189 (2.0 days, respectively. The isolates 1189, 1022 e 866 of M. anisopliae and 483, IPA198 and 604 of B. bassiana, at 10(8 e 10(9 conidia mL-1 are promissing for use the integrated control of A. argillacea larvae, but M. anisopliae seems more effective.O curuquerê-do-algodoeiro (Alabama argillacea é considerado uma das principais pragas do algodoeiro herbáceio no Brasil, com ocorrência comum em vários estágios de crescimento da cultura. Este trabalho avaliou a patogenicidade e selecionou isolados dos fungos entomopatogênicos Metarhizium anisopliae e Beauveria bassiana, para lagartas do curuquerê-do-algodoeiro Alabama argillacea. Os experimentos foram conduzidos a 27 ± 2°C, 70 ± 5 % de UR e fotofase de 12 h. Foram utilizados 10 isolados de cada fungo na concentração de 10(8 conídios mL-1 sobre larvas de A. argillacea no 3º instar. Os isolados selecionados (seis de M. anisopliae e sete de B. bassiana foram pulverizados com micropulverizador manual (DeVilbiss nas concentrações de 10(6, 10(7, 10(8 e 10(9 conídios mL-1, em delineamento inteiramente casualizado. As porcentagens de mortalidade confirmada de lagartas de A. argillacea ocasionadas pelos isolados de M. anisopliae, variaram de 4,5 a 91,2%, nas diferentes concentrações, sendo que o isolado 1189 de M. anisopliae, na concentração 10(9 con��dios mL-1, proporcionou a maior mortalidade. O isolado 645 de B. bassiana, também proporcionou a mais elevada mortalidade na concentração 10(9 conídios mL-1, seguido dos isolados 634, IPA 198 e 604. O isolado 1189 de M. anisopliae apresentou o tempo letal (TL50 igual a 2,0 dias, sendo portanto menor que os demais isolados, na concentração de 10(9 conídios mL-1. Para B. bassiana, o menor TL50 foi do isolado 483 (4,1 dias. Os isolados 1189, 1022 e 866 de M. anisopliae e 483, IPA198 e 604 de B. bassiana nas concentrações 10(8 e 10(9 conídios mL-1, mostraram-se promissores para incorporação no manejo integrado de A. argillacea, destacando-se aqueles de M. anisopliae.

    Full Text Available Entomopathogenic fungus Beauveria bassiana is currently used as a biocontrol agent for agricultural pests. The infection process involves extracellular enzymes such as proteases and chitinases that degrade the cuticle of the insects. The objective of this work was to evaluate kinetic parameters of pH, temperature, ionic concentration and time of reaction on chitinases activity. The fungus B. bassiana CG432 was cultivated on coffee berry borer Hypothenemus hampei (Ferrari and the conidia grown on insect were used to prepare the inoculum containing 108conídia/mL. These conidia were inoculated at 1% (v/v in culture liquid medium containing D-glucose (10g, yeast extract (5g, NaNO3 (1,58g, Na2HPO4.7H2O (1,05g, KCl (1g, MgSO4.7H2O (0,6g and KH2PO4 (0,36g per liter. The cultivation was carried at 28°C and 180rpm during 5 days. Culture fluid was obtained by filtration and centrifugation at 8.000g, and the chitinases were isolated and concentrated by ultrafiltration using 10 and 100kDa cut off membranes under nitrogen pressure. Chitinase activity was detected and quantified using N-acetylglucosamine released by hydrolysis of colloidal chitin at 40 to 60ºC, at 50, 100 and 200 mM ionic concentrations of buffers sodium acetate (pH 4.0 to 6.0; sodium phosphate (pH 6.0 to 8.0; and Glycine-NaOH (pH 8.0 to 10.0 during 60 minutes. Maximum chitinase activity was at 45ºC and pH 5.5, and was also high at pH 6.0 and pH 8.5 using 50mM buffer. The chitinase activity increased and was stable during an hour at optimum conditions of the reaction, shown the stable nature of this enzyme.Beauveria bassiana é um fungo entomopatogênico utilizado no controle biológico de insetos-praga que infestam produtos agrícolas. O mecanismo de infecção envolve a produção de enzimas extracelulares, como proteases e quitinases que degradam a cutícula dos insetos. O objetivo deste trabalho foi avaliar parâmetros cinéticos de pH, temperatura, concentração iônica e tempo de reação sobre a atividade de quitinases. O fungo B. bassiana CG432 foi repicado em broca do café Hypothenemus hampei (Ferrari e utilizado para preparar o inóculo contendo 108conídios ativados/mL. Estes conídios foram inoculados 1% (v/v em meio de cultura líquido constituído por D-glicose (10g, extrato de levedura (5g, NaNO3 (1,58g, Na2HPO4.7H2O (1,05g, KCl (1g, MgSO4.7H2O (0,6g e KH2PO4 (0,36g por litro. O cultivo foi conduzido a 28°C e 180rpm durante 5 dias. O fluido extracelular do cultivo foi obtido por filtração e centrifugação a 8.000g, e as quitinases foram isoladas e concentradas por ultrafiltração entre membranas de 10 e 100kDa sob pressão de nitrogênio. A atividade das quitinases foi determinada pela quantificação da N-acetilglicosamina liberada pela hidrólise da quitina coloidal durante 60 minutos de incubação a temperaturas de 40 a 60ºC, concentrações iônicas dos tampões acetato de sódio pH 4,0 a 6,0; fosfato de sódio pH 6,0 a 8,0; e glicina-NaOH pH 8,0 a 10,0, a 50, 100 e 200 mM. A atividade das quitinases foi máxima a 45ºC, em pH 5,5, mas também foi elevada em pH 6,0 e 8,5 em concentração iônica de 50mM. A atividade de quitinases aumentou durante uma hora de incubação demonstrando estabilidade das enzimas nas condições ótimas da reação.

The fungus Trichoderma sp. was inoculated on PDA culture medium, 0, 48, 120 and 168 hours after inoculation of the same plates with either B. bassiana (isolate 634 or M. anisopliae (isolate E-9. The radial growth of fungal colonies was measured 48 and 120 hours after Trichoderma sp. inoculation. Trichoderma sp. affected the development of both entomopathogenic fungi when inoculated simultaneously or 48 hours later. B. bassiana and M. anisopliae had normal development when inoculated 168 hours before Trichoderma sp. The effect of a toxic extract from Trichoderma sp. on the entomopathogenic fungi was also evaluated. Aliquots of 0.1, 0.5, 1.0 and 5.0 ml of extract were added to 100 ml of PDA medium, used to grow the entomopathogens. The radial growth of B. bassiana and M. anisopliae colonies grown in the presence of the extract were measured and the number of conidia produced per colony was counted. With 5% of extract in the medium, mycelial growth and conidiogenesis of B. bassiana decreased. M. anisopliae growth was affected by culture medium containing 1% or more of the extract.

    Full Text Available Entomopathogenic production techniques are developed with the objective of increasing productivity and reducing costs of the process. The objective of this study was to evaluate Beauveria bassiana biomass production in liquid media and conidiogenesis in a biphasic process. The liquid media were: CF (crysalid flour, PD (potato dextrose and CFPD (crysalid flour+potato+dextrose. The evaluation periods for biomass production were: 24, 48, 72, 96, 120 and 144 hours. For production by biphasic process different quantities of liquid media (5, 10, 15 and 20 mL with different incubation periods (24, 48 and 72 hours, were added on the pre-cooked rice (200 g with conidia production evaluation after 10 days. CFPD media was the most productive biomass in all evaluated periods. In the biphasic process, bigger conidia production were attained when it was utilized fungi biomass produced in CF and CFPD (2.7 x 1012 and 2.8 x 1012 conidia/g of rice for rice inoculation. The quantities of 5, 15, 20 mL of liquid media, inoculated on the rice were not statistically different. The incubation periods of 24 and 48 hours of the fungus in the liquid media, gave bigger cionidiogenesis then 72 hours. The data show the necessity of carbon and nitrogen for biomass production in the liquid media and for conidiogenesis in the solid media. Also with these informations it was possible to optimize the biphasic process, adding 5 mL of the liquid media CFPD on the rice (200 g with 24 hours of incubation.Técnicas de produção de fungos entomopatogênicos são desenvolvidas buscando aumentar a produtividade desses patógenos e reduzir custos do processo.

    Full Text Available The Competition involved actions on two contiguous blocks of housing, one of them with serious structural problems that requiered its demolition and replacement with a new bioclimatic building, The other building was renovated by environmental and accessibility alterations. After the initial study of the study of the climate and environment, the design decisions matched these conditiosn in order to achieve a better environemental sustainability together with other technical, formal and social values. In both blocks, yhe bad orientation of the existing blocks (with façades to the east and west han been corrected, folding the skin of the building to capture sunligth to the interior in winter and provide protection in the summer, creating a series of “climatisation galleries” with capture windows facing south-east in the living rooms of the houses. These galleries are protected by shading elements on the glass which prevent the greenhouse effect in summer and are protected by exterior blinds that also create shade and chambers that prevent cooling by cold air convection outside in the winter. The exterio woodwork consist of profiles that break the thermal brigde and double glazing with low emissions treatment. In the new block, to improve the summer conditions inside the houses and taking into account that active cooling is needed on a few days of the year when temperatures are high, natual cooling chimneys have been provided. Ther are two types of façade walls, one consisting iof walls with great heat inertia and exterior rendered insulation and the other also within insulation on the exterior layer but with a ventilated chamber finished with prefabricated panels. Together, the buildings achieve a level of insulation an suitability that is about 200% of the requiered by standards. Total accessibility has been provided for all the new and existing houses and low consumtion lifts installed.El Concurso planteaba la actuación sobre dos bloques de viviendas contiguos, uno de ellos con graves problemas estructurales, que obligaron a su demolición, ha sido sustituido por un nuevo edificio bioclimático. El otro edificio ha sido objeto de una rehabilitación para su adecuación medioambiental y de accesibilidad. Tras el estudio previo del clima y del entorno, las decisiones sobre el diseño correspondían a estas condiciones de manera que se logra la mejor adecuación ambiental junto con otros valores técnicos, formales y sociales. En ambos bloques la mala orientación de los bloques existentes (con fachadas al Este y Oeste, ha sido corregida, plegando la piel del edificio para conseguir la captación de radiación solar hacia el interior en invierno y su protección en verano, creando una serie de “galerías de climatización”, con ventanas captoras orientadas a sureste en zonas de estancia de las viviendas. Estas galerías están protegidas por elementos de sombra sobre los vidrios que eliminan el efecto invernadero en verano y quedan protegidas por persianas exteriores que también dan sombra y crean cámaras que evitan el enfriamiento por convención del aire frío exterior en invierno. Las carpinterías exteriores están realizadas con perfiles que consiguen la rotura del puente térmico y acristaladas con vidrio doble de baja emisividad. En el edificio de nueva planta, para mejorar las condiciones de verano en el interior de las viviendas y teniendo en cuenta que haría falta una refrigeración activa unos pocos días al año en los que las temperaturas máximas se elevan, se han previsto unas chimeneas de refrigeración natural. Se han realizado dos tipos de cerramiento de fachada: una, compuesta por muros de gran inercia térmica con aislamiento exterior revocado, y otra, también con el aislamiento en la capa exterior, pero con cámara ventilada acabada con paneles prefabricados. El conjunto de los edificios consigue un nivel de aislamiento y adecuación superior en un 200% al exigible por normativa. Para todas las viviendas nuevas y ya existentes, se ha conseguido accesibilidad total a las mismas, y la dotación de ascensores de bajo consumo.

    Full Text Available AbstractPneumocystis jirovecii is an unculturable fungus and the causative agent of Pneumocystis pneumonia, a life-threatening opportunistic infection. Although molecular diagnosis is often based on the mtLSU rRNA mitochondrial gene due to its greater sensitivity, physiology and the dynamics of the mitochondria in this fungus remains largely unknown. We developed and optimized six real-time PCR assays in order to determine the copy number of four mitochondrial genes (mtSSU rRNA, mtLSU rRNA, NAD1 and CYTB in comparison to nuclear genome (DHPS and HSP70 and tested 84 bronchoalveolar fluids of patients at different stages of the infection. Unexpectedly, we found that copy number of mitochondrial genes varied from gene to gene with mtSSU rRNA gene being more represented (37 copies than NAD1 (23 copies, mtLSU rRNA (15 copies and CYTB (6 copies genes compared to nuclear genome. Hierarchical clustering analysis (HCA allowed us to define five major clusters, significantly associated with fungal load (p=0.029, in which copy number of mitochondrial genes was significantly different among them. More importantly, copy number of mtLSU rRNA, NAD1 and CYTB but not mtSSU rRNA differed according to P. jirovecii physiological state with a decreased number of copies when the fungal load is low. This suggests the existence of a mixture of various subspecies of mtDNA that can harbor different amplification rates. Overall, we revealed here an unexpected plasticity and dynamics of P. jirovecii mitochondrial DNA that vary according to P. jirovecii’s physiological state.

  15. Entomophily, ornithophily and anemochory in the self-incompatible Boswellia ovalifoliolata Bal. & Henry (Burseraceae, an endemic and endangered medicinally important tree species

    Directory of Open Access Journals (Sweden)

    A.J.S. Raju

    2012-07-01

    Full Text Available Boswellia ovalifoliolata (Burseraceae is a narrow endemic and endangered deciduous tree species. Its flowering, fruiting and seed dispersal events occur in a leafless state during the dry season. The flowers are small, bisexual, mildly odoriferous and actinomorphic; weakly protandrous but strictly self-incompatible. While insects and sunbirds pollinate the flowers, floral characteristics suggest that entomophily is the principal mode. Both bud and flower feeding by a weevil and flower and fruit feeding by the Palm Squirrel have been found to affect the success of sexual reproduction. The Garden Lizard serves as a predator of pollinating insects, especially bees and wasps, thus influencing pollination of this tree species. Fruit set in open pollination is below 10%, rising to 34% in manual cross-pollination. Limitation of cross-pollination, space constraints for seed production from all flower ovules and availability of limited resources in rocky, dry litter of the forest floor appear to constrain higher fruit set. Mature fruits dehisce and disseminate their lightweight, papery winged seeds with the aid of wind. The study site being windy provides the necessary driving force for effective dispersal of seeds away from parent trees. Seed germination occurs following rainfall but further growth depends on soil water and nutritional status. The success rate of seedling recruitment is highly limited, and it could be due to nutrient-poor soil and water stress resulting from dry spells during the rainy season.

Design: prospective. Patients: this study included 22 patients in whom a hydrostatic dilatation of the papilla with large balloons was performed between June 2005 and April 2006. Patients had multiple large stones, tapered distal common bile duct, peri-/intradiverticular papilla, previous sphincterotomy, or Billroth-II surgery. Esophageal, pyloric and colonic CRE dilatation balloons with diameters ranging from 12 to 20 mm (Boston Scientific Corporation were used. Results: stone removal was achieved in a single session in all patients (100%. Most procedures (73% did not require an extended exploration time. There were no complications. Hyperamilasemia was detected in 18% of patients. Conclusions: hydrostatic papillary dilatation with large balloons is a simple, effective, and safe technique for the removal of difficult stones located in the distal common bile duct. It does not add to exploration time, nor increases complications, and reduces the need for lithotripsy. Further studies are needed to define the usefulness of this technique.

    Investigating the hydrogeochemical properties of wetlands allow us to protect them in a sustainable fashion in global scale. Edremit-Dalyan coastal wetland (EDCW) is located in southern part of Biga Peninsula (Mount Ida) which is the most important eco-tourism center in Turkey. Water sampling was done from the hydrologic basin of coastal wetland that consists of a geothermal site, ore deposits area, treatment facility area and olive tree breeding area. EC values of wetland vary between 440 and 2190 μS/cm and water type shows a shift from CaHCO3 to NaClSO4. Al, As, Cd, Cu, Fe, Pb and Zn concentrations exceed the tolerance limits in wetland area probably due to ore deposits around the Edremit Plain. Concentrations of As are high in wetland area exceeding both aquatic life and drinking water As standards of 10 μg/L by as much as 3 times are observed. The dominant As species is As (III). For the living organisms, this situation can be dangerous. Oxygen-18 and deuterium composition of the samples between -7.18 and -6.13‰, and between -42.6 and -34.4‰, respectively in the study area and all the waters are of meteoric origin. Oxygen-18 enrichment can be observed around Derman and coastal zone due to the geothermal activity and evaporation, respectively.

    This work evaluates for the first time the relationships between copper-tolerance, -solubilization and -bioaccumulation in the entomopathogen Beauveria bassiana exposed to Bordeaux mixture, copper oxychloride or copper hydroxide. Bordeaux mixture was highly detrimental to fungus, by inhibiting the growth totally at the recommended dose (RD) and 2×RD. Copper hydroxide and copper oxychloride were found to be less toxic, reducing fungus growth, sporulation and conidial germination in an average of 29  %, 30 % and 58 %, respectively. These two copper forms were the easiest to solubilize, to precipitate and the most accumulated by B. bassiana, suggesting the involvement of all these processes on fungus copper-tolerance.

    Full Text Available Abstract The fungus Beauveria bassiana is naturally found in poultry houses and causes high rates of mortality in Alphitobius diaperinus. Laboratory and field experiments have shown the potential of this fungus as an insect control agent. However, in poultry houses, bacteria as Salmonella, can be found and have been studied alternative control methods for this pathogen. Thus, this study aimed to evaluate the effect of plant extracts and a disinfectant on the fungus Beauveria bassiana (strain Unioeste 4. Conidial viability, colony-forming unit (CFU counts, vegetative growth, conidia production, insecticidal activity of the fungus and compatibility were used as parameters in the evaluation of the effect of these products on the fungus. Alcoholic and aqueous extracts of jabuticaba (Myrciaria cauliflora (Mart., guava (Psidium guajava (L., and jambolan (Syzygium cumini (L., at concentrations of 10% as well as the commercial disinfectant, Peroxitane® 1512 AL, were evaluated at the recommended concentrations (RC, 1:200 (RC, 0.5 RC and 2 RC. There was a negative influence of alcoholic and aqueous extracts of jabuticaba, guava and three dilutions of Peroxitane on the viability of conidia. The CFUs and vegetative growth of the fungus were affected only by the Peroxitane (all dilutions. For conidial production, the aqueous extract of guava had a positive effect, increasing production, while the Peroxitane at the R and RC concentrations resulted in a negative influence. The mortality of A. diaperinus, caused by the fungus after exposure to these products, was 60% for the peracetic acid at 0.5 RC, and above 80% for the extracts. Thus, the results showed that all the extracts and Peroxitane at RC 0.5 are compatible with the fungus B. bassiana Unioeste 4, however only the extracts had a low impact on inoculum potential.

    Full Text Available The entomopathogenic fungus Beauveria bassiana is a promising agent for use in insect control. Its pathogenic activity, as well as other factors such as temperature that can interfere with its development, should be assessed, thus, establishing the foundations for B. bassiana use in biological control programs. The objective of this study was to select and induce tolerance of B. bassiana isolates to high and low temperatures and to assess their virulence before and after exposure to those temperatures. A pre-selection test was performed, in which the tolerance of isolates to stress temperatures was tested and compared to the ideal growth temperature of 25 °C for this organism. For the isolates/temperature combinations resulting in growth, conidia germination and colony-forming units (CFUs were assessed. The isolates Unioeste 4 and Unioeste 40 exhibited >95% germinated conidia at 16 and 31 °C. Thereafter, they underwent four consecutive passages at maximum and minimum tolerated temperatures (10 and 37 °C. A significant difference in germination was observed between the two isolates at all temperatures tested. More CFUs were observed for Unioeste 4 compared to Unioeste 40 at all temperatures, and in the case of the latter, there was no difference in CFU formation at 10 and 25 °C. For both isolates, decreased vegetative growth was observed at 37 °C. Recovery of virulence was observed in both isolates, as determined by insect mortality. No relationship was observed between production of the enzyme Pr1 and the virulence of the isolates.

    Full Text Available Background & objectives: Biological control of sandflies using entomopathogenic fungi is a possible alternativeto the expensive synthetic chemical control. It is potentially sustainable, less hazardous, and relatively inexpensiveand merits further investigations. The objective of this study was to identify the most pathogenic fungal isolate(sto sandflies in the laboratory.Methods: Isolates of entomopathogenic fungi Metarhizium anisopliae and Beauveria bassiana were screenedfor their pathogenicity against Phlebotomus duboscqi. Adult flies were contaminated using the technique describedby Migiro et al (2010. Briefly, flies were exposed to 0.1 g of dry conidia evenly spread on a cotton velvet clothcovering the inner side of a cylindrical plastic tube (95 mm long × 48 mm diam. In all 25 sandflies weretransferred into the cylindrical tube and allowed to walk on the velvet for one minute, after which they weretransferred from the velvet into the cages in Perplex. Insects in the control treatments were exposed to fungusfree velvet cloth before being transferred into similar cages. The treatments were maintained at 25 ± 2°C,60–70% RH and 12L: 12D photoperiod. The experiment was replicated 5 times. The most pathogenic isolateswere selected for further studies.Results: A total of 19 isolates were screened against adult sandflies in the laboratory. Mortality in the controlswas approximately 16.8 ± 1.7 %. All the isolates were found to be pathogenic to P. duboscqi. Mortality rangedbetween 76.8 and 100% on all the fungal isolates tested. The lethal time taken to 50% (LT50 and 90% (LT90(mortality ranged from 3.0–7.8 days and from 5.3–16.2 days, respectively. The virulent isolates, causing mortalitiesof 97.5–100%, were selected for further studies.Interpretation & conclusion: The high susceptibility of sandflies to entomopathogenic fungi suggests that fungiare potential alternatives to chemical control methods. We conclude that application of entomopathogenic fungicould result in acute mortalities of sandflies and reduction of parasite transmission and subsequently, reductionof leishmaniasis risk. This method of biological control has great potential as a new strategy for leishmaniasiscontrol

As suspensões de conídios foram preparadas a partir de fungos produzidos em meio de arroz, e cada bioensaio foi constituído de quatro tratamentos nas concentrações 10(5, 10(6, 10(7, 10(8 conídios/ml e um grupo-controle. A análise constou da observação do percentual de mortalidade, 15 dias após o tratamento ou após a ecdise de adultos. Foram observadas diferenças significativas entre os tratamentos quanto à mortalidade para todos os isolados e todos os instares. Nos grupos tratados houve aumento considerável na mortalidade à medida que se aumentava a concentração de conídios na suspensão. Conclui-se que todos os isolados testados causaram mortalidade em testes in vitro sobre esses estádios evolutivos, sugerindo o controle do A. cajennense pela ação desses fungos.This work aimed at the evaluation of the in vitro susceptibility of Amblyomma cajennense nimphs and adults to isolates of Beauveria bassiana and Metarhizium anisopliae fungi. Three isolates of M. anisopliae (959, 319 e E9 and two of B. bassiana (986 e 747 were used. Conidia suspensions were made from fungi grown up in a rice culture medium and each test consisted of four treated groups (10(5, 10(6, 10(7, 10(8 conidia/ ml plus a control group. Viability of individuals was assessed 15 days after treatment or after adult ecdisis. Significative differences were found for all treatments and for all stages studied. A large reduction in the viability of ticks was observed, and this effect increased as conidia concentration raised. Based upon the results obtained, it can be concluded that all isolates tested presented an in vitro lethality for the biological stages of A. cajennense evaluated, suggesting a potential use in the biological control of this tick species.

    Rheumatoid arthritis is a common autoimmune disease.Many inflammatory cytokines are involved in the pathological process of RA,among which IL-1 is a kind of important inflammatory mediator playing a key role in the chronic inflammation progress in consequence of body’s natural responses or pathological conditions.Under the influ-ence of anti-inflammatory cytokine,however ,in vitro inflammatory effects of IL-1 can be inhibited or abolished by a particularly powerful inhibitor-IL-1Ra.The current study shows that IL-1 can combine with IL-1RⅠ and it can acti-vate signaling transduction pathway and contribute to the erosion of bone and articular cartilage.Furthermore,IL-1 may induce the expression of other inflammatory cytokine and aggravate joint destruction synergistically.On the contrary,IL-1Ra may compaginate IL-1RⅠ to inhibit the biological effect of IL-1.Therefore,the dynamic equilibrium of IL-1 and IL-1Ra has great importance to the prognosis of RA and it will be great significance.Understanding IL-1 and IL-1Ra balance in attack of RA has important role for prevention,treatment and outcome of this disease.%类风湿性关节炎(RA)为常见的自身免疫疾病,其发生、发展与众多炎性因子相关,白细胞介素1(IL-1)是一种炎症反应的重要介质,在人体的自然反应和病理条件导致慢性炎症的发展中都有重要作用,然而在抗炎细胞因子的影响下,体外IL-1炎症作用可以被一个特别强大的抑制剂---IL-1受体拮抗剂(IL-1Ra)抑制或者消除。目前研究显示,IL-1通过与Ⅰ型IL-1受体结合,可激活系列信号转导通路进而诱发关节软骨和骨侵蚀,同时可诱导其他炎性因子表达,协同加剧关节破坏,而IL-1Ra可牢固结合Ⅰ型IL-1受体,抑制IL-1的生物学效应,因此,RA患者体内IL-1/IL-1Ra的动态平衡对于该病的转归至关重要。深入对RA发病中IL-1/IL-1Ra平衡的认识对该病的预防、治疗及转归具有重要作用。

It is suggested that this practice was the result, in colonial times, of the mimetic appropriation and structural transformation of the Christian legend of St Christopher and the Christ Child into the myth of a cannibalistic giant and his evil infant son. The notion that children could become potent witches would have been reinforced in postcolonial times by epidemics affecting mostly adults. If this is so, the belief in child sorcery would be one of those unforeseen and tragic products of the colonial encounter. In their eagerness to exorcise colonial violence Peruvian Arawaks turned against themselves, unleashing violence against their children’s bodies and through them to the body politic at large. This practice, thought to have been abandoned in the 1970s, has reappeared with renewed force in recent times as a result of the violence and social disruption resulting from confrontations with insurgent groups and the Peruvian Army.

    The accretion of interstellar medium onto the central super massive black holes is widely accepted as the source of the gigantic energy released by the active galactic nuclei. But few pieces of observational evidence have been confirmed directly demonstrating the existence of the inflows. The absorption line system in the spectra of quasar SDSS J112526.12+002901.3 presents an interesting example, in which the rarely detected hydrogen Balmer and metastable He I absorption lines are found redshifted to the quasar's rest frame along with the low-ionization metal absorption lines Mg II, Fe II, etc. The repeated SDSS spectroscopic observations suggest a transverse velocity smaller than the radial velocity. The motion of the absorbing medium is thus dominated by infall. The He I* lines present a powerful probe to the strength of ionizing flux, while the Balmer lines imply a dense environment. With the help of photoionization simulations, we find the absorbing medium is exposed to the radiation with ionization param...

    Full Text Available Abstract Background The main hypothesis of this study is that neutral pH, low glucose degradation product (GDP peritoneal dialysis (PD fluid better preserves residual renal function in PD patients over time compared with conventional dialysate. Methods/Design Inclusion criteria are adult PD patients (CAPD or APD aged 18-81 years whose first dialysis was within 90 days prior to or following enrolment and who have a residual GFR ≥ 5 ml/min/1.73 m2, a urine output ≥ 400 ml/day and an ability to understand the nature and requirements of this trial. Pregnant or lactating patients or individuals with an active infection at the time of enrolment, a contra-indication to PD or participation in any other clinical trial where an intervention is designed to moderate rate of change of residual renal function are excluded. Patients will be randomized 1:1 to receive either neutral pH, low GDP dialysis solution (Balance® or conventional dialysis solution (Stay.safe® for a period of 2 years. During this 2 year study period, urinary urea and clearance measurements will be performed at 0, 3, 6, 9, 12, 18 and 24 months. The primary outcome measure will be the slope of residual renal function decline, adjusted for centre and presence of diabetic nephropathy. Secondary outcome measures will include time from initiation of peritoneal dialysis to anuria, peritoneal small solute clearance, peritoneal transport status, peritoneal ultrafiltration, technique survival, patient survival, peritonitis rates and adverse events. A total of 185 patients has been recruited into the trial. Discussion This investigator-initiated study has been designed to provide evidence to help nephrologists determine the optimal dialysis solution for preserving residual renal function in PD patients.

    Full Text Available ABSTRACT The control of Alphitobius diaperinus is based mainly on chemical insecticides, and the indiscriminate and incorrect use of these products has led to failures in insect control. Thus, it is important to monitor the efficiency of the products available on the market and to develop alternative insect control strategies. The present study evaluated the effect of a new product (cypermethrin-6% under laboratory and field conditions and assessed its in-vitro compatibility with the fungus Beauveria bassiana (Unioeste 4 isolate. Its efficiency in dry powder and wettable powder formulations was also assessed in the laboratory through comparison with a similar insecticide (cypermethrin-5% at five different concentrations. The field assays were conducted in two commercial broiler breeder houses (Treated and Control, applying the new product on the litter at the manufacturer's recommended concentration (RC. Germination, vegetative growth, conidial production, number of colony forming units (CFUs and insecticidal activity of the fungus were used to evaluate the compatibility of the insecticide. The effects of the cypermethrin-6% product and cypermethrin-5% were equivalent in the laboratory, and the new product exhibited better performance at lower concentrations (1/4RC, ⅛RC. The strategy applied in the field reduced the insect population in up to 96% after 75 days. Additionally, all concentrations of cypermethrin-6% were compatible with the fungus under the evaluated in-vitro conditions. Therefore, the new product is considered selective for B. bassiana. Further studies are necessary to assess its compatibility under field conditions, consolidating this strategy as a viable alternative for managing this pest.

    While bonding between d 10 atoms and ions in molecular systems has been well studied, less attention has been paid to interactions between such seemingly closed shell species in extended inorganic solids. In this contribution, we present visualizations of the electronic structures of the delafossites ABO 2 (A = Cu, Ag, Au) with particular emphasis on the nature of d 10-d 10 interactions in the close packed plane of the coinage metal ion. We find that on going from Cu to Ag to Au, the extent of bonding between A and A increases. However, the structures (in terms of distances) of these compounds are largely determined by the strongly ionic B IIIO interaction and for the larger B ions Sc, In and Y, the A atoms are sufficiently well-separated that AA bonding is almost negligible. We also analyze some interesting differences between Ag and Au, including the larger AO covalency of the Au. The trends in electronic structure suggest that the Ag and Au compounds are not good candidate transparent conducting oxides.

    We present a detailed investigation of the variability of 428 C IV and 235 Si IV Broad Absorption Line (BAL) troughs identified in multi-epoch observations of 291 quasars by the Sloan Digital Sky Survey-I/II/III. These observations primarily sample rest-frame timescales of 1-3 yr over which significant rearrangement of the BAL wind is expected. We derive a number of observational results on, e.g., the frequency of BAL variability, the velocity range over which BAL variability occurs, the primary observed form of BAL-trough variability, the dependence of BAL variability upon timescale, the frequency of BAL strengthening vs. weakening, correlations between BAL variability and BAL-trough profiles, relations between C IV and Si IV BAL variability, coordinated multi-trough variability, and BAL variations as a function of quasar properties. We assess implications of these observational results for quasar winds. Our results support models where most BAL absorption is formed within an order-of-magnitude of the wind-l...

    We present the results of a variability study of broad absorption lines (BALs) in a uniformly radio-selected sample of 28 BAL quasars using the archival data from the first bright quasar survey (FBQS) and the Sloan Digital Sky Survey (SDSS), as well as those obtained by ourselves, covering time scales $\\sim 1-10$ years in the quasar's rest-frame. The variable absorption troughs are detected in 12 BAL quasars. Among them, five cases showed strong spectral variations and are all belong to a special subclass of overlapping iron low ionization BALs (OFeLoBALs). The absorbers of \\ion{Fe}{2} are estimated to be formed by a relative dense (\\mbox{$n\\rm _{e} > 10^6~cm^{-3}$}) gas at a distance from the subparsec scale to the dozens of parsec-scale from the continuum source. They differ from those of invariable non-overlapping FeLoBALs (non-OFeLoBALs), which are the low-density gas and locate at the distance of hundreds to thousands parsecs. OFeLoBALs and non-OFeLoBALs, i.e., FeLoBALs with/without strong BAL variations...

  11. Is there a connection between Broad Absorption Line Quasars and Narrow Line Seyfert 1 galaxies?

    2014-01-01

    We consider whether Broad Absorption Line Quasars (BAL QSOs) and Narrow Line Seyfert 1 galaxies (NLS1s) are similar, as suggested by Brandt & Gallagher (2000) and Boroson (2002). For this purpose we constructed a sample of 11 BAL QSOs from existing Chandra and Swift observations. We found that BAL QSOs and NLS1s both operate at high Eddington ratios L/Ledd, although BAL QSOs have slightly lower L/Ledd. BAL QSOs and NLS1s in general have high FeII/H$\\beta$ and low [OIII]/H$\\beta$ ratios following the classic 'Boroson \\& Green' eigenvector 1 relation. We also found that the mass accretion rates $\\dot{M}$ of BAL QSOs and NLS1s are more similar than previously thought, although some BAL QSOs exhibit extreme mass accretion rates of more than 10 \\msun/year. These extreme mass accretion rates may suggest that the black holes in BAL QSOs are relativistically spinning. Black hole masses in BAL QSOs are a factor of 100 larger than NLS1s. From their location on a M-$\\sigma$ plot, we find that BAL QSOs contain fu...

    Fibrosing alveolitis (FA) is a frequent and often fatal complication of systemic sclerosis (SSC). Alveolar inflammation has been recognized as a primary event in the pulmonary manifestation of SSC. To evaluate the significance of the alveolitis in SSC, we performed bronchoalveolar lavage (BAL) and correlated the generated data with changes in lung function over time. Seventy nine SSC patients with pulmonary involvement were followed for 56.8 +/- 3.1 wk (mean +/- SEM) with a repeat lung function test at the end of the follow-up period. During follow-up, 38 patients were treated with a systemic immunosuppressive regimen. For evaluation, patients were assigned to two groups according to whether their BAL cell differential was normal (inactive BAL) or abnormal (active BAL: i.e., polymorphonuclear leukocytes > 5% and/or lymphocytes > 15%). Active BAL was associated with more severe lung function impairment than was inactive BAL, and patients with active BAL deteriorated during follow-up if untreated. In contrast, treated patients with active BAL stabilized or improved. In summary, active alveolitis as characterized by BAL is associated with progressive pulmonary disease in SSC patients, and a significant positive effect of immunosuppressive therapy on the course of pulmonary disease was observed in patients with active BAL.

    BACKGROUND: The numbers of airway CD8 and B lymphocytes are increased in COPD patients, suggesting an autoimmune process. CD4-regulatory T cells control autoimmunity but have not been studied in patients with COPD. OBJECTIVE: To compare T-regulatory cell numbers in the BAL from COPD patients......, smokers with normal lung function, and healthy nonsmokers (HNS). METHODS: BAL and peripheral blood mononuclear cell (PBMC) samples were obtained from 26 COPD patients, 19 smokers, and 8 HNS. Flow cytometry was performed for regulatory phenotypic markers. RESULTS: COPD patients had increased BAL CD8...... numbers compared to smokers and HNS. CD4 numbers were similar between groups. There was increased BAL CD4CD25(bright) expression in smokers (median 28.8%) and COPD patients (median 23.1%) compared to HNS (median 0%). Increased FoxP3 expression was confirmed in BAL CD4CD25(bright) cells. BAL CD4CD25 cells...

  14. The clinical utility of bronchoalveolar lavage in interstitial lung disease - is it really useful?

    Science.gov (United States)

    Meyer, Keith C

    2014-04-01

    Bronchoalveolar lavage (BAL) can be a very useful tool in the diagnosis of interstitial lung disease, but BAL must be performed properly and the retrieved BAL fluid adequately processed and analyzed to allow accurate conclusions to be drawn from BAL analysis. A differential cell count of nucleated immune cells can show cell patterns that suggest or support certain diagnoses, and other testing (stains and cultures for infectious pathogens, malignant cell cytology) can be performed on BAL fluid that can also aid in diagnosis. When combined with the results of a careful history, physical examination, thoracic imaging, and other pertinent laboratory testing, the BAL analysis may allow a confident diagnosis of a specific interstitial lung disease to be made without proceeding to more invasive testing (e.g., surgical lung biopsy) that is associated with increased risk of complications.

    Full Text Available Este artículo explora los mecanismos por los cuales el período de violencia en el país sigue impactando las universidades, esta vez mediante la violencia simbólica expresada en formas de estigmatización desde un actor interno (la familia y desde un actor externo (los medios de comunicación. En ese contexto, los jóvenes de esta generación construyen nuevas formas de participación política; la universidad como espacio de deliberación y de acción política universitaria se ve mediada por el temor a ser señalado y estigmatizado como una consecuencia casi natural de la violencia, sin descuidar el desinterés por la política que prevalece en las últimas décadas. Pese a ello, encontramos que los jóvenes han llevado su experiencia participativa hacia nuevas formas de acción que, sin proponérselo o reconocerlo, son también plataformas políticas. Concluimos que entre el estigma -la supuesta presencia del Movadef- y la falta de canales institucionales, los universitarios se encuentran en una etapa no cohesionada pero que podría configurarse como acción colectiva.

    Full Text Available No período de 1974 a 1987, 620 pacientes foram submetidos a cirurgia de revascularização do miocárdio, na Casa de Saúde Sáo Raimundo, com 28 óbitos, 4,5% de mortalidade. Dezenove pacientes foram submetidos a procedimentos associados: prótese aórtica, mitral, ou ressecçáo de aneurisma ventricular. Os pacientes com idade acima de 70 anos e os submetidos a reoperaçáo estão incluídos. Não houve seleção dos casos. O método de proteção miocárdica foi o do pinçamento intermitente da aorta, hipotermia corporal de 30ºC e hipotermia tópica com solução salina gelada. A síndrome de baixo débito, a mediastinite em paciente diabético, anemia pré-operatória em paciente com angina instável acima de 70 anos de idade, tamponamento cardíaco tardio, endarterectomia não satisfatória, desatenção no uso de nipride no pós-operatório, choque após a protamina, sangramento, acidente vascular cerebral, coma hiperosmolar foram, entre outras, as causas de óbito. Da presente experiência, concluímos que o pinçamento intermitente da aorta, associado à hipotermia, é um aceitável método de preservação do miocárdio.From 1974 to December 1987, 620 patients were submitted to myocardial revascularization, with 28 deaths, 4.5% mortality. Nineteen patients received associated procedures: 14 ventricular aneurysmectomy and 5 valvular prosthesis. The method of myocardial protection was intermitent clamping of the aorta, topical and body hypothermia of 30ºC. From this experience we conclude that this method offers a satisfactory myocardial preservation.

MÉTODOS: Estudo experimental com 141 profissionais de saúde (médicos, médicos residentes, fisioterapeutas, enfermeiros e técnicos de enfermagem que ventilaram um pulmão artificial ajustado para reproduzir o pulmão de um recém-nascido a termo, utilizando ventilador pulmonar manual autoinflável com cinco diferentes modos de manuseio: com as duas mãos (10 dedos e com uma mão, utilizando cinco, quatro, três e dois dedos. Valores de pico de pressão e volume corrente foram registrados pelo pulmão artificial. RESULTADOS: Observou-se alta variabilidade nos valores das variáveis estudadas. A média do pico de pressão foi 39,73 cmH2O (IC95% 37,32-42,13, variando de 2,5 a 106,3 cmH2O, e do volume foi 39,56 mL (IC95% 36,86-42,25, variando de 4 a 88 mL. Não foi detectada influência significativa da profissão sobre as variáveis estudadas (p > 0,05. Observou-se que o modo de manuseio do ventilador pulmonar manual influenciou significativamente o pico de pressão e o volume corrente (p OBJECTIVE: To evaluate how different ways of handling the neonatal self-inflating bag influence peak pressure and tidal volume. METHODS: This is an experimental study involving 141 different professionals (physicians, resident physicians, physiotherapists, nurses, and nursing technicians, who ventilated an artificial lung, adjusted to simulate the lung of a term neonate, using a self-inflating bag. Each professional handled the ventilator in five different ways: a using both hands (10 fingers; and, with only one hand, b five fingers, c four fingers, d three fingers, and e two fingers. Peak pressure and tidal volume data were recorded by the artificial lung equipment. RESULTS: Both variables showed high variability, from 2.5 to 106.3 cmH2O (mean = 39.73 cmH2O; 95%CI 37.32-42.13 for peak pressure, and from to 4 to 88 mL (mean = 39.56 mL; 95%CI 36.86-42.25 for tidal volume. There was no significant influence of the profession on any of the variables (p > 0.05. However, bag handling significantly influenced both peak pressure and tidal volume (p < 0.0001, which were higher when the operator used both hands. CONCLUSION: The results indicate that most professionals delivered excessively high peak pressures and tidal volumes, which could increase the risk of barotrauma and volutrauma, especially when both hands were used to ventilate. On the other hand, a small number of professionals delivered insufficient pressure and volume for adequate lung expansion and ventilation. The delivery of inadequate ventilation was not dependent on profession.

    Neutral Helium multiplets, HeI*3189,3889,10830 are very useful diagnostics to the geometry and physical conditions of the absorbing gas in quasars. So far only a handful of HeI* detections have been reported. Using a newly developed method, we detected HeI*3889 absorption line in 101 sources of a well-defined sample of 285 MgII BAL quasars selected from the SDSS DR5. This has increased the number of HeI* BAL quasars by more than one order of magnitude. We further detected HeI*3189 in 50% (52/101) quasars in the sample. The detection fraction of HeI* BALs in MgII BAL quasars is about 35% as a whole, and increases dramatically with increasing spectral signal-to-noise ratios, from 18% at S/N = 35. This suggests that HeI* BALs could be detected in most MgII LoBAL quasars, provided spectra S/N is high enough. Such a surprisingly high HeI* BAL fraction is actually predicted from photo-ionization calculations based on a simple BAL model. The result indicates that HeI* absorption lines can be used to search for BAL q...

    We present a two-epoch SDSS and Gemini/GMOS+WHT/ISIS variability study of 50 broad absorption line quasars of redshift range 1.9 < z < 4.2, containing 38 Si IV and 59 C IV BALs and spanning rest-frame time intervals of approximately 10 months to 3.7 years. We find that 35/50 quasars exhibit one or more variable BALs, with 58% of Si IV and 46% of C IV BALs showing variability across the entire sample. On average, Si IV BALs show larger fractional change in BAL pseudo equivalent width than C IV BALs, as referenced to an unabsorbed continuum+emission-line spectrum constructed using non-negative matrix factorisation. No correlation is found between BAL variability and quasar luminosity, suggesting that ionizing continuum changes do not play a significant role in BAL variability (assuming the gas is in photoionization equilibrium with the ionizing continuum). A subset of 14 quasars have one variable BAL from each of Si IV and C IV with significant overlap in velocity space and for which variations are in the...

    The origin of broad-absorption-line quasars (BAL QSOs) is still an open issue. Accounting for ~20% of the QSO population, these objects present broad absorption lines in their optical spectra generated from outflows with velocities up to 0.2c. In this work we present the results of a multi-frequency study of a well-defined radio-loud BAL QSO sample, and a comparison sample of radio-loud non-BAL QSOs, both selected from the Sloan Digital Sky Survey (SDSS). We aim to test which of the currently-popular models for the BAL phenomenon - `orientation' or 'evolutionary' - best accounts for the radio properties of BAL quasars. Observations from 1.4 to 43 GHz have been obtained with the VLA and Effelsberg telescopes, and data from 74 to 408 MHz have been compiled from the literature. The fractions of candidate GHz-peaked sources are similar in the two samples (36\\pm12% vs 23\\pm8%), suggesting that BAL QSOs are not generally younger than non-BAL QSOs. BAL and non-BAL QSOs show a large range of spectral indices, consist...

    1999-02-01

    BalTrim is an Excel(R) spreadsheet designed to calculate the inertial mass properties and ballast trim weight for either an assembled reentry vehicle (RV) or reentry body (RB). With this application, the user enters known mass properties and global coordinates for each subcomponent of the assembly, and BalTrim calculates the mass properties of the total assembly. Then, using the assembly mass properties, BalTrim calculates the necessary amount of ballast trim weight required to dynamically and statically balance the assembly mass properties. The final mass properties and trim ballast weight calculated with BalTrim agree with physicaly measured values.

    We report NuSTAR observations of a sample of six X-ray weak broad absorption line (BAL) quasars. These targets, at z=0.148-1.223, are among the optically brightest and most luminous BAL quasars known at z330 times weaker than expected for typical quasars. Our results from a pilot NuSTAR study of two low-redshift BAL quasars, a Chandra stacking analysis of a sample of high-redshift BAL quasars, and a NuSTAR spectral analysis of the local BAL quasar Mrk 231 have already suggested the existence of intrinsically X-ray weak BAL quasars, i.e., quasars not emitting X-rays at the level expected from their optical/UV emission. The aim of the current program is to extend the search for such extraordinary objects. Three of the six new targets are weakly detected by NuSTAR with 33%) of intrinsically X-ray weak objects among the BAL quasars with significantly weak <10 keV emission. We suggest that intrinsically X-ray weak quasars might be preferentially observed as BAL quasars.

    A case of BOOP occurring after radiotherapy for breast cancer was reported. TBLB and BAL were performed at the time of diagnosis. This case suggested that radiographic changes began in the irradiated area, then later spread to non-irradiated areas. In this article, we discussed the peculiary radiographic image, pathological manifestation, BAL characteristics and clinical course in this sequela. (author)

  11. Discovery of a variable broad absorption line in the BL Lac object PKS B0138-097

    We report the discovery of a broad absorption line (BAL) of ~104 km s-1in width in the previously known BL Lac object PKS 0138-097,which we tentatively identified as an Mg Ⅱ BAL.This is the first detection of a BAL,which is sometimes seen in powerful quasars with high accretion rates,in a BL Lac object.The BAL was clearly detected in its spectra spanning two epochs at a high luminosity state taken in the Sloan Digital Sky Survey (SDSS),while it disappeared in three SDSS spectra taken at a low luminosity state.The BAL and its variability pattern were also found in its historical multi-epoch spectra in the literature,but have been overlooked previously.In its high resolution radio maps,PKS 0138-097 shows a core plus a onesided parsec-scale jet.The BAL variability can be interpreted as follows:The optical emission is dominated by the core in a high state and by the jet in a low state and the BAL material is located between the core and jet so that the BAL appears only when the core is shining.Our discovery suggests that outflows may also be produced in active galactic nuclei at a low accreting state.

    1998-01-01

    We report the discovery of five broad-absorption-line (BAL) QSOs in a complete sample of 111 ultraviolet excess (UVX) QSO candidates also detected in the NRAO VLA Sky Survey. All five BAL QSOs, which include two high-ionization BAL QSOs and three low-ionization BAL QSOs, are formally radio-loud. Of QSOs with z > 0.4, 3+/-2% show low-ionization BALs, and of QSOs with z > 1.5, all radio-loud, 9+/-5% show BALs; these frequencies are consistent with those of optical surveys. While the first reported radio-loud BAL QSO, FIRST J155633.8+351758, is likely to be heavily dust reddened and thus less radio-loud than indicated by its observed radio-to-optical luminosity, these QSOs are UVX selected and probably free of significant dust along the line of sight. We point out unusual features in two of the BAL QSOs and discuss the significance finding these heretofore rare objects.

    A study was undertaken to measure the blood alcohol levels (BALs) of five men and five women after they had consumed seven middies of Emu 2.2 (2.2% alcohol by volume) beer in 1 hour. This study was conducted in response to a newspaper advertisement which depicted a well-known football player drinking seven middies of Emu 2.2 beer over 1 hour and registering a BAL of 0.012%. As predicted, the BALs of the ten adults varied considerably, but all greatly exceeded the very low result obtained by the football player. More importantly, from the point of view of road safety, all ten BALs exceeded the 0.02% probationary driver limit in Western Australia, and two of the BALs were above the 0.05% legal limit for driving in several other Australian states.

    AIM: To characterize and evaluate the therapeutic efficacy of bioartificial liver (BAL) as compared to that of continuous hemodiafiltration (CHDF) with plasma exchange (PE), which is the current standard therapy for fulminant hepatic failure (FHF) in Japan.METHODS: Pigs with hepatic devascularization were divided into three groups: (1) a non-treatment group (NT; n = 4); (2) a BAL treatment group (BAL; n = 4),(3) a PE + CHDF treatment group using 1.5 L of normal porcine plasma with CHDF (PE + CHDF, n = 4). Our BAL system consisted of a hollow fiber module with 0.2 μm pores and 1 × 1010 of microcarrier-attached hepatocytes inoculated into the extra-fiber space. Each treatment was initiated 4 h after hepatic devascularization.RESULTS: The pigs in the BAL and the PE + CHDF groups survived longer than those in the NT group. The elimination capacity of blood ammonia by both BAL and PE + CHDF was significantly higher than that in NT.Aromatic amino acids (AAA) were selectively eliminated by BAL, whereas both AAA and branched chain amino acids, which are beneficial for life, were eliminated by PE + CHDF.Electrolytes maintenance and acid-base balance were better in the CPE + CHDF group than that in the BAL group.CONCLUSION: Our results suggest that PE + CHDF eliminate all factors regardless of benefits, whereas BAL selectively metabolizes toxic factors such as AAA.However since PE + CHDF maintain electrolytes and acid-base balance, a combination therapy of BAL plus CPE + CHDF might be more effective for FHF.

    Full Text Available Background: Accurate diagnosis and appropriate treatment of ventilator associated pneumonia (VAP is crucial for good outcomes. Endotracheal suctioning is performed in ventilated patients as part of routine care and for tracheal toileting. Aim: We evaluated if quantitative endotracheal aspirate (ETA was a suitable alternative to bronchoalveolar lavage (BAL for suspected VAP. In addition we assessed if surveillance ETA guided antibiotic selection for subsequent VAP. Setting and Design: Prospective study in the surgical intensive care unit (ICU of a tertiary hospital in India. Materials and Methods: Two hundred consecutive patients with mean (standard deviation APACHE II score of 12.3±5 and requiring mechanical ventilation beyond 48 hours underwent surveillance ETA cultures. A second ETA and BAL were performed if the patient developed features of VAP. The threshold for microbiological diagnosis of VAP was taken as 10 5 colony forming units/ml (cfu/ml for ETA and 10 4 cfu/ml for BAL. Statistical Analysis: The sensitivity and specificity of surveillance and concurrent ETA aspirate cultures were compared with BAL cultures. RESULTS: VAP was suspected clinically and corroborated radiologically in 27/177 patients (15.3%. Although microbiological support for VAP was obtained by ETA in 19 patients, bronchoscopy was possible only in 13 patients, 8 of whom had isolates at significant threshold. Of the 16 organisms isolated from BAL, 11 were of significant threshold with 9/11 (82% BAL isolates having a similar antibiogram to a concurrent ETA. Only one BAL isolate (9%, at significant threshold, was not isolated on a concurrent ETA. On the other hand just 6/11 BAL isolates (55% had an identical antibiogram to surveillance ETA. BAL had 3 additional isolates (27% at significant threshold not isolated on surveillance ETA. Conclusions: Concurrent quantitative ETA could substitute BAL cultures for VAP. Surveillance ETA at 48 hours of ventilation does not appear to

  6. Broad Absorption Line Variability in Radio-Loud Quasars

    CERN Document Server

    Welling, C A; Brandt, W N; Capellupo, D M; Gibson, R R

    2014-01-01

    We investigate C IV broad absorption line (BAL) variability within a sample of 46 radio-loud quasars (RLQs), selected from SDSS/FIRST data to include both core-dominated (39) and lobe-dominated (7) objects. The sample consists primarily of high-ionization BAL quasars, and a substantial fraction have large BAL velocities or equivalent widths; their radio luminosities and radio-loudness values span ~2.5 orders of magnitude. We have obtained 34 new Hobby-Eberly Telescope (HET) spectra of 28 BAL RLQs to compare to earlier SDSS data, and we also incorporate archival coverage (primarily dual-epoch SDSS) for a total set of 78 pairs of equivalent width measurements for 46 BAL RLQs, probing rest-frame timescales of ~80-6000 d (median 500 d). In general, only modest changes in the depths of segments of absorption troughs are observed, akin to those seen in prior studies of BAL RQQs. Also similar to previous findings for RQQs, the RLQs studied here are more likely to display BAL variability on longer rest-frame timescal...

    He, Zhi-Cheng; Jiang, Xiao-Lei; Ge, Xue

    2015-01-01

    The variability of broad absorption lines is investigated for a sample of 188 broad-absorption-line (BAL) quasars (QSOs) ($z > 1.7$) with at least two-epoch observations from the Sloan Digital Sky Survey Data Release 7 (SDSS DR7), covering a time-scale of about 0.001 -- 3 years in the rest frame. Considering only the longest time-scale between epochs for each QSO, 73 variable regions in the \\civ BAL troughs are detected for 43 BAL QSOs. The proportion of BAL QSOs showing variable regions increases with longer time-interval than about 1 year in the rest frame. The velocity width of variable regions is narrow compared to the BAL-trough outflow velocity. For 43 BAL QSOs with variable regions, it is found that there is a medium strong correlation between the variation of the continuum luminosity at 1500 \\AA\\ and the variation of the spectral index. With respect to the total 188 QSOs, larger proportion of BAL QSOs with variable regions appears bluer during their brighter phases, which implies that the origin of BA...

  8. A Variable PV Broad Absorption Line and Quasar Outflow Energetics

    CERN Document Server

    Capellupo, Daniel M; Barlow, Tom A

    2014-01-01

    Broad absorption lines (BALs) in quasar spectra identify high velocity outflows that might exist in all quasars and could play a major role in feedback to galaxy evolution. The viability of BAL outflows as a feedback mechanism depends on their kinetic energies, as derived from the outflow velocities, column densities, and distances from the central quasar. We estimate these quantities for the quasar, Q1413+1143 (redshift $z_e = 2.56$), aided by the first detection of PV $\\lambda\\lambda$1118,1128 BAL variability in a quasar. In particular, PV absorption at velocities where the CIV trough does not reach zero intensity implies that the CIV BAL is saturated and the absorber only partially covers the background continuum source (with characteristic size 22.3 (cm^-2). Variability in the PV and saturated CIV BALs strongly disfavors changes in the ionization as the cause of the BAL variability, but supports models with high-column density BAL clouds moving across our lines of sight. The observed variability time of ...

    2005-07-01

    Full Text Available Abstract Background Gastroesophageal reflux disease (GORD can cause respiratory disease in children from recurrent aspiration of gastric contents. GORD can be defined in several ways and one of the most common method is presence of reflux oesophagitis. In children with GORD and respiratory disease, airway neutrophilia has been described. However, there are no prospective studies that have examined airway cellularity in children with GORD but without respiratory disease. The aims of the study were to compare (1 BAL cellularity and lipid laden macrophage index (LLMI and, (2 microbiology of BAL and gastric juices of children with GORD (G+ to those without (G-. Methods In 150 children aged Results BAL neutrophil% in G- group (n = 63 was marginally but significantly higher than that in the G+ group (n = 77, (median of 7.5 and 5 respectively, p = 0.002. Lipid laden macrophage index (LLMI, BAL percentages of lymphocyte, eosinophil and macrophage were similar between groups. Viral studies were negative in all, bacterial cultures positive in 20.7% of BALs and in 5.3% of gastric aspirates. BAL cultures did not reflect gastric aspirate cultures in all but one child. Conclusion In children without respiratory disease, GORD defined by presence of reflux oesophagitis, is not associated with BAL cellular profile or LLMI abnormality. Abnormal microbiology of the airways, when present, is not related to reflux oesophagitis and does not reflect that of gastric juices.

    1999-10-01

    Aim of the study was to evaluate treatment efficacy and safety of a scaled-up version of our porcine hepatocytes based BAL system in pigs with complete liver ischemia (LIS). Thirty-one pigs underwent total devascularization of the liver (LIS) by termino-lateral porta-caval shunts and sutures around the bile duct, the common hepatic and gastroduodenal arteries and their accessory branches. The hepato-duodenal ligament was completely transected. Four experimental groups were studied: the first control group (LIS Control, n = 10) received glucose infusion only, the second control group (LIS Plasmapheresis, n = 8) was connected to a centrifugal plasma-separator with a bottle representing the bioreactor volume, the third control group (LIS Empty-BAL, n = 5) received BAL treatment without cells, and the treated group (LIS Cell-BAL, n = 8) was connected for a maximum period of 24 hours to our scaled-up BAL seeded with around 14 billion viable primary porcine hepatocytes. BAL treatment significantly prolonged life in large animals (approximately 35 kg) with complete LIS (Controls, mean +/- SEM: 33.1 +/- 3 h, Cell-BAL: 51.1 +/- 3.4 h; p = 0.001; longest survivor 63 h). In addition, blood ammonia and total bilirubin levels decreased significantly, indicating metabolic activity of porcine hepatocytes in the bioreactor. No significant differences were noticed among the three control groups, indicating that there was no device effect and that the plasmapheresis procedure was well tolerated. No important adverse effects were observed.

    2016-01-01

    We present results from the largest systematic investigation of broad absorption line (BAL) acceleration to date. We use spectra of 140 quasars from three Sloan Digital Sky Survey programs to search for global velocity offsets in BALs over timescales of ~2.5-5.5 years in the quasar rest frame. We carefully select acceleration candidates by requiring monolithic velocity shifts over the entire BAL trough, avoiding BALs with velocity shifts that might be caused by profile variability. The CIV BALs of two quasars show velocity shifts consistent with the expected signatures of BAL acceleration, and the BAL of one quasar shows a velocity-shift signature of deceleration. In our two acceleration candidates, we see evidence that the magnitude of the acceleration is not constant over time; the magnitudes of the change in acceleration for both acceleration candidates are difficult to produce with a standard disk-wind model or via geometric projection effects. We measure upper limits to acceleration and deceleration for ...

    Mechanical ventilation deteriorates previously injured lung, but little is known about its effect on healthy human lung. This work was designed to assess the effect of prolonged mechanical ventilation on bronchoalveolar lavage (BAL) fluid composition of patients without acute lung injury. Twenty-two ventilated patients (tidal volume 8-10 mL x kg(-1), positive end-expiratory pressure 3-5 cmH2O) without lung injury, who did not develop any complication from the respiratory system during the 2-week study period, were studied. They were subjected to three consecutive BALs, the first during 36 h from intubation, the second at the end of the first week of mechanical ventilation and the third at the end of the second week of mechanical ventilation. Total BAL protein increased during mechanical ventilation (148 +/- 62, 381 +/- 288, 353 +/- 215 microg x mL(-1) BAL for the first, second and third BAL, respectively). In contrast, BAL phospholipids decreased (2.7 +/- 1.1, 1.4 +/- 0.6, 1.2 +/- 0.7 microg x mL(-1) BAL, respectively). Large surfactant aggregates were reduced and inflammatory markers, such as platelet activating factor (PAF), PAF-acetylhydrolase and neutrophils, significantly increased after 1 week, but partially remitted after 2 weeks of mechanical ventilation. In summary, this study demonstrates that prolonged mechanical ventilation even of patients without acute lung injury is associated with the presence of inflammatory markers and surfactant alterations.

  13. Amino Acid Residues Critical for the Specificity for Betaine Aldehyde of the Plant ALDH10 Isoenzyme Involved in the Synthesis of Glycine Betaine1[W][OA

    Plant Aldehyde Dehydrogenase10 (ALDH10) enzymes catalyze the oxidation of ω-primary or ω-quaternary aminoaldehydes, but, intriguingly, only some of them, such as the spinach (Spinacia oleracea) betaine aldehyde dehydrogenase (SoBADH), efficiently oxidize betaine aldehyde (BAL) forming the osmoprotectant glycine betaine (GB), which confers tolerance to osmotic stress. The crystal structure of SoBADH reported here shows tyrosine (Tyr)-160, tryptophan (Trp)-167, Trp-285, and Trp-456 in an arrangement suitable for cation-π interactions with the trimethylammonium group of BAL. Mutation of these residues to alanine (Ala) resulted in significant Km(BAL) increases and Vmax/Km(BAL) decreases, particularly in the Y160A mutant. Tyr-160 and Trp-456, strictly conserved in plant ALDH10s, form a pocket where the bulky trimethylammonium group binds. This space is reduced in ALDH10s with low BADH activity, because an isoleucine (Ile) pushes the Trp against the Tyr. Those with high BADH activity instead have Ala (Ala-441 in SoBADH) or cysteine, which allow enough room for binding of BAL. Accordingly, the mutation A441I decreased the Vmax/Km(BAL) of SoBADH approximately 200 times, while the mutation A441C had no effect. The kinetics with other ω-aminoaldehydes were not affected in the A441I or A441C mutant, demonstrating that the existence of an Ile in the second sphere of interaction of the aldehyde is critical for discriminating against BAL in some plant ALDH10s. A survey of the known sequences indicates that plants have two ALDH10 isoenzymes: those known to be GB accumulators have a high-BAL-affinity isoenzyme with Ala or cysteine in this critical position, while non GB accumulators have low-BAL-affinity isoenzymes containing Ile. Therefore, BADH activity appears to restrict GB synthesis in non-GB-accumulator plants. PMID:22345508

    The incidence of broad absorption lines (BALs) in quasar samples is often interpreted in the context of a geometric unification model consisting of an accretion disc and an associated outflow. We use the the Sloan Digital Sky Survey (SDSS) quasar sample to test this model by examining the equivalent widths (EWs) of C IV 1550 Å, Mg II 2800 Å, [O III] 5007 Å and C III] 1909 Å. We find that the emission line EW distributions in BAL and non-BAL quasars are remarkably similar - a property that is inconsistent with scenarios in which a BAL outflow rises equatorially from a geometrically thin, optically thick accretion disc. We construct simple models to predict the distributions from various geometries; these models confirm the above finding and disfavour equatorial geometries. We show that obscuration, line anisotropy and general relativistic effects on the disc continuum are unlikely to hide an EW inclination dependence. We carefully examine the radio and polarisation properties of BAL quasars. Both suggest that they are most likely viewed (on average) from intermediate inclinations, between type 1 and type 2 AGN. We also find that the low-ionization BAL quasars in our sample are not confined to one region of `Eigenvector I' parameter space. Overall, our work leads to one of the following conclusions, or some combination thereof: (i) the continuum does not emit like a geometrically thin, optically thick disc; (ii) BAL quasars are viewed from similar angles to non-BAL quasars, i.e. low inclinations; (iii) geometric unification does not explain the fraction of BALs in quasar samples.

    Broad Absorption Line Quasars (BAL QSOs) have been found to be associated with extremely compact radio sources. These reduced dimensions can be either due to projection effects or these objects might actually be intrinsically small. Exploring these two hypotheses is important to understand the nature and origin of the BAL phenomenon because orientation effects are an important discriminant between the different models proposed to explain this phenomenon. In this work we present VLBA observations of 5 BAL QSOs and discuss their pc-scale morphology.

    The clinical demand on rapid microbiological diagnostic is constantly increasing. PCR coupled to electrospray ionization-mass spectrometry, PCR/ESI-MS, offers detection and identification of over 750 bacteria and Candida species directly from clinical specimens within 6 hours. In this study, we investigated the clinical performance of the IRIDICA BAC LRT Assay for detection of bacterial pathogens in 121 bronchoalveolar lavage (BAL) samples that were received consecutively at our bacterial laboratory for BAL culture. Commensal or pathogenic microorganisms were detected in 118/121 (98%) BAL samples by PCR/ESI-MS, while in 104/121 (86%) samples by routine culture (PLegionella pneumophila, Bordetella pertussis, Norcadia species and Mycoplasma pneumoniae. In conclusion, PCR/ESI-MS detected a broad range of potential pathogens with equal or superior sensitivity compared to conventional methods within few hours directly from BAL samples. This novel method might thus provide a relevant tool for diagnostics in critically ill patients. PMID:28085931

    2011-08-01

    Cytologic analysis of bronchoalveolar lavage (BAL) fluid is used for lung cancer diagnosis. We describe a patient with a history of rectal carcinoma who presented with a new lung mass. BAL was performed, with positron emission tomography-computed tomography the following day. There was mildly increased fluoro-deoxy-D-glucose uptake in areas of the lung parenchyma with new ground-glass opacification. This created ambiguity in staging, clarified 2 weeks later by a computed tomography showing complete resolution of the ground-glass opacity. Clinicians should be aware that BAL may cause increased pulmonary fluoro-deoxy-D-glucose uptake, making accurate radiologic interpretation problematic. We suggest that to optimize positron emission tomography-computed tomography, studies should not be performed within 24 hours of BAL.

    The claim that high intake of both ethanol and fat is essential to induce fatty liver and high blood alcohol levels (BAL) was tested. Two groups of rats were fed liquid diets containing 26% and 36% of calories as ethanol respectively. After 4 weeks, all rats were bled for BAL and some were sacrificed to obtain liver morphology. Remaining rats in Group 1 (26% ethanol) were switched to 36% ethanol diet and Group 2 (36% ethanol) to 26% ethanol diet. All rats were sacrificed after 4 weeks to obtain blood for BAL and liver morphology. The results indicate that high ethanol intake and high fat ingestion is not the criterion for induction of fatty liver. Inadequate ingestion of macronutrients plays a major role in alcoholic fatty liver and BAL.

    Full Text Available Aim: The aim was to study the bronchoalveolar lavage (BAL technique in evaluating the local immune response of pig immunized with Pasteurella multocida bacterin vaccine. Materials and Methods: Weaned piglets were immunized with formalin-inactivated P52 strain of P. multocida bacterin and evaluated for pulmonary immune response in BAL fluid. BAL was performed before vaccination and at different post vaccination days. The BAL fluid was assayed using enzyme-linked immunosorbent assay to study the development of P. multocida specific antibody isotypes and also evaluated for different cell populations using standard protocol. Results: The average recovery percentage of BAL fluid varies from 58.33 to 61.33 in vaccinated and control group of piglets. The BAL fluid of vaccinated pigs showed increase in antibody titer up to 60th days post vaccination (8.98±0.33, IgG being the predominant isotype reached maximum titer of 6.12±0.20 on 45th days post vaccination, followed by IgM and a meager concentration of IgA could be detected. An increased concentration of the lymphocyte population and induction of plasma cells was detected in the BAL fluid of vaccinated pigs. Conclusion: Though intranasal vaccination with P. multocida plain bacterin vaccine could not provoke a strong immune response, but is promising as lymphocyte population was increased and plasma cells were detected. BAL can be performed repeatedly up to 3/4 months of age in pigs to study pulmonary immune response without affecting their health.

    Epstein-Barr virus (EBV) is a lymphotropic herpesvirus causing clinically self-limiting but lifelong persisting infections. Although several severe diseases (e.g., Hodgkin's disease) are associated with EBV, its role in lower respiratory tract infections is still elusive. The prevalence of EBV, herpes simplex virus (HSV) and cytomegalovirus (CMV) in bronchoalveolar fluid (BAL) samples was evaluated in a retrospective study. BAL samples from 135 patients in the intensive or coronary care unit (ICU/ICC) at University Hospital Frankfurt/Main (Germany) were investigated using an in-house real-time PCR to detect EBV-, HSV- and CMV-specific DNA. Overall, herpesvirus DNA was detected in n = 82/135 BAL samples (60.7 %). Besides mono-infections with either EBV or HSV, concomitant infection with EBV and HSV DNA was most frequent, whereby the relative HSV viral load was typically higher. Patients with HSV-positive BAL required mechanical ventilation on average 5 days longer than patients with HSV-negative BAL (p = 0.006). Additionally, the proinflammatory cytokine IL-6 was significantly elevated in sera of patients positive for EBV in comparison with patients with EBV-negative BAL (p = 0.01). This study demonstrates a high prevalence of herpesviruses in BAL samples of ICU/ICC patients. The detection of one or more herpesvirus in BAL is strongly associated with the duration of ventilation and patient's age. The association between IL-6 levels and EBV detection should be evaluated in further studies.

  16. Cell recovery in bronchoalveolar lavage fluid in smokers is dependent on cumulative smoking history.

    Reza Karimi

    Full Text Available BACKGROUND: Smoking is a risk factor for various lung diseases in which BAL may be used as a part of a clinical investigation. Interpretation of BAL fluid cellularity is however difficult due to high variability, in particular among smokers. In this study we aimed to evaluate the effect of smoking on BAL cellular components in asymptomatic smokers. The effects of smoking cessation, age and gender were also investigated in groups of smokers and exsmokers. METHODS: We performed a retrospective review of BAL findings, to our knowledge the largest single center investigation, in our department from 1999 to 2009. One hundred thirty two current smokers (48 males and 84 females and 44 ex-smokers (16 males and 28 females were included. A group of 295 (132 males and 163 females never-smokers served as reference. RESULT: The median [5-95 pctl] total number of cells and cell concentration in current smokers were 63.4 [28.6-132.1]×10(6 and 382.1 [189.7-864.3]×10(6/L respectively and correlated positively to the cumulative smoking history. Macrophages were the predominant cell type (96.7% [90.4-99.0] followed by lymphocytes (2% [0.8-7.7] and neutrophils (0.6% [0-2.9]. The concentration of all inflammatory cells was increased in smokers compared to never smokers and ex-smokers. BAL fluid recovery was negatively correlated with age (p<0.001. Smoking men had a lower BAL fluid recovery than smoking women. CONCLUSION: Smoking has a profound effect on BAL fluid cellularity, which is dependent on smoking history. Our results performed on a large group of current smokers and ex-smokers in a well standardized way, can contribute to better interpretation of BAL fluid cellularity in clinical context.

  17. High concentrations of pepsin in bronchoalveolar lavage fluid from children with cystic fibrosis are associated with high interleukin-8 concentrations.

    LENUS (Irish Health Repository)

    McNally, P

    2012-02-01

    BACKGROUND: Gastro-oesophageal reflux is common in children with cystic fibrosis (CF) and is thought to be associated with pulmonary aspiration of gastric contents. The measurement of pepsin in bronchoalveolar lavage (BAL) fluid has recently been suggested to be a reliable indicator of aspiration. The prevalence of pulmonary aspiration in a group of children with CF was assessed and its association with lung inflammation investigated. METHODS: This was a cross-sectional case-control study. BAL fluid was collected from individuals with CF (n=31) and healthy controls (n=7). Interleukin-8 (IL-8), pepsin, neutrophil numbers and neutrophil elastase activity levels were measured in all samples. Clinical, microbiological and lung function data were collected from medical notes. RESULTS: The pepsin concentration in BAL fluid was higher in the CF group than in controls (mean (SD) 24.4 (27.4) ng\\/ml vs 4.3 (4.0) ng\\/ml, p=0.03). Those with CF who had raised pepsin concentrations had higher levels of IL-8 in the BAL fluid than those with a concentration comparable to controls (3.7 (2.7) ng\\/ml vs 1.4 (0.9) ng\\/ml, p=0.004). Within the CF group there was a moderate positive correlation between pepsin concentration and IL-8 in BAL fluid (r=0.48, p=0.04). There was no association between BAL fluid pepsin concentrations and age, sex, body mass index z score, forced expiratory volume in 1 s or Pseudomonas aeruginosa colonisation status. CONCLUSIONS: Many children with CF have increased levels of pepsin in the BAL fluid compared with normal controls. Increased pepsin levels were associated with higher IL-8 concentrations in BAL fluid. These data suggest that aspiration of gastric contents occurs in a subset of patients with CF and is associated with more pronounced lung inflammation.

  18. Reversible, partial inactivation of plant betaine aldehyde dehydrogenase by betaine aldehyde: mechanism and possible physiological implications.

    In plants, the last step in the biosynthesis of the osmoprotectant glycine betaine (GB) is the NAD(+)-dependent oxidation of betaine aldehyde (BAL) catalysed by some aldehyde dehydrogenase (ALDH) 10 enzymes that exhibit betaine aldehyde dehydrogenase (BADH) activity. Given the irreversibility of the reaction, the short-term regulation of these enzymes is of great physiological relevance to avoid adverse decreases in the NAD(+):NADH ratio. In the present study, we report that the Spinacia oleracea BADH (SoBADH) is reversibly and partially inactivated by BAL in the absence of NAD(+)in a time- and concentration-dependent mode. Crystallographic evidence indicates that the non-essential Cys(450)(SoBADH numbering) forms a thiohemiacetal with BAL, totally blocking the productive binding of the aldehyde. It is of interest that, in contrast to Cys(450), the catalytic cysteine (Cys(291)) did not react with BAL in the absence of NAD(+) The trimethylammonium group of BAL binds in the same position in the inactivating or productive modes. Accordingly, BAL does not inactivate the C(450)SSoBADH mutant and the degree of inactivation of the A(441)I and A(441)C mutants corresponds to their very different abilities to bind the trimethylammonium group. Cys(450)and the neighbouring residues that participate in stabilizing the thiohemiacetal are strictly conserved in plant ALDH10 enzymes with proven or predicted BADH activity, suggesting that inactivation by BAL is their common feature. Under osmotic stress conditions, this novel partial and reversible covalent regulatory mechanism may contribute to preventing NAD(+)exhaustion, while still permitting the synthesis of high amounts of GB and avoiding the accumulation of the toxic BAL.

    Lewisite is a potent chemical warfare arsenical vesicant that can cause severe skin lesions. Today, lewisite exposure remains possible during demilitarization of old ammunitions and as a result of deliberate use. Although its cutaneous toxicity is not fully elucidated, a specific antidote exists, the British anti-lewisite (BAL, dimercaprol) but it is not without untoward effects. Analogs of BAL, less toxic, have been developed such as meso-2,3-dimercaptosuccinic acid (DMSA) and have been employed for the treatment of heavy metal poisoning. However, efficacy of DMSA against lewisite-induced skin lesions remains to be determined in comparison with BAL. We have thus evaluated in this study the therapeutic efficacy of BAL and DMSA in two administration modes against skin lesions induced by lewisite vapor on SKH-1 hairless mice. Our data demonstrate a strong protective efficacy of topical application of dimercapto-chelating agents in contrast to a subcutaneous administration 1 h after lewisite exposure, with attenuation of wound size, necrosis and impairment of skin barrier function. The histological evaluation also confirms the efficacy of topical application by showing that treatments were effective in reversing lewisite-induced neutrophil infiltration. This protective effect was associated with an epidermal hyperplasia. However, for all the parameters studied, BAL was more effective than DMSA in reducing lewisite-induced skin injury. Together, these findings support the use of a topical form of dimercaprol-chelating agent against lewisite-induced skin lesion within the first hour after exposure to increase the therapeutic management and that BAL, despite its side-effects, should not be abandoned. - Highlights: • Topically applied dimercapto-chelating agents reduce lewisite-induced skin damage. • One topical application of BAL or DMSA is sufficient to reverse lewisite effects. • Topical BAL is more effective than DMSA to counteract lewisite-induced skin damage.

  20. Macrophage activation in acute exacerbation of idiopathic pulmonary fibrosis.

    Full Text Available Acute exacerbation (AE of idiopathic pulmonary fibrosis (IPF is a common cause of disease acceleration in IPF and has a major impact on mortality. The role of macrophage activation in AE of IPF has never been addressed before.We evaluated BAL cell cytokine profiles and BAL differential cell counts in 71 IPF patients w/wo AE and in 20 healthy volunteers. Twelve patients suffered from AE at initial diagnosis while sixteen patients developed AE in the 24 months of follow-up. The levels of IL-1ra, CCL2, CCL17, CCL18, CCL22, TNF-α, IL-1β, CXCL1 and IL-8 spontaneously produced by BAL-cells were analysed by ELISA.In patients with AE, the percentage of BAL neutrophils was significantly increased compared to stable patients. We found an increase in the production rate of the pro-inflammatory cytokines CXCL1 and IL-8 combined with an increase in all tested M2 cytokines by BAL-cells. An increase in CCL18 levels and neutrophil counts during AE was observed in BAL cells from patients from whom serial lavages were obtained. Furthermore, high baseline levels of CCL18 production by BAL cells were significantly predictive for the development of future AE.BAL cell cytokine production levels at acute exacerbation show up-regulation of pro-inflammatory as well as anti-inflammatory/ M2 cytokines. Our data suggest that AE in IPF is not an incidental event but rather driven by cellular mechanisms including M2 macrophage activation.

    Chelation for heavy metal intoxication began more than 70 years ago with the development of British anti-lewisite (BAL; dimercaprol) in wartime Britain as a potential antidote the arsenical warfare agent lewisite (dichloro[2-chlorovinyl]arsine). DMPS (unithiol) and DMSA (succimer), dithiol water-soluble analogs of BAL, were developed in the Soviet Union and China in the late 1950s. These three agents have remained the mainstay of chelation treatment of arsenic and mercury intoxication for mor...

    Organic Dust Toxic Syndrome (ODTS) is a flu-like syndrome that can occur after inhalation of cotton, grain, wood chip dusts, or other organic dusts or aerosols. We investigated whether inflammatory pulmonary responses occur, even after relatively brief, low-level wood chip mulch exposure. Six volunteers were exposed to wood chip mulch dust. Total dust and/or endotoxin levels were measured in five subjects. Pulmonary function and peripheral blood counts were measured before and after exposure in each subject. Bronchoalveolar lavage (BAL) was performed in each subject after exposure, and cell, cytokine, and protein concentrations were measured. Control BAL without previous exposure was also performed on three of the subjects. Three of six subjects had symptoms consistent with ODTS. No clinically relevant or statistically significant changes in pulmonary function tests after exposure were found. Three subjects manifested a marked elevation in neutrophil percentage in their BAL (range, 10 to 57%). When these three subjects underwent control BAL, the postexposure comparison demonstrated an increase in neutrophil levels of 154 +/- 89 x 10(3)/mL (mean +/- standard error; P = 0.22). The mean increase in BAL interleukin-8 levels after exposure, compared with paired control values, was 11.2 +/- SE 2.5 pg/mL (P = 0.047). There was also an increase in BAL interleukin-6 levels that reached borderline significance (6.4 +/- SE 2.0 pg/mL; P = 0.08). Tumor necrosis factor levels were increased in all three subjects' BAL as well (0.4 +/- SE 0.2 pg/mL), but this change was not statistically significant (P = 0.2). Our findings of increased BAL proinflammatory cytokine and neutrophil levels are consistent with the theory that cytokine networking in the lung may mediate ODTS.

    The increasing prevalence of resistance among pathogenic microorganisms to common antibiotics has become one of the most significant concerns in modern medicine. Nanotechnology offers a new alternative to develop materials with interesting applications in many areas of biological sciences and medicine. While some bismuth derivatives have been employed to treat vomiting, nausea, diarrhea, and stomach pain, the antimicrobial properties of bismuth in its nanoparticulate form have not been extensively studied. The objective of this investigation was to analyze the bactericidal, fungicidal, and antibiofilm activities of bismuth dimercaptopropanol nanoparticles (BisBAL NPs) against oral microbes. The nanoparticles are composed of 18.7 nm crystallites on average and have a rhombohedral structure, agglomerating into chains-like or clusters of small nanoparticles. Our results showed that stable colloidal BisBAL NPs inhibited Streptococcus mutans and Streptococcus gordonii growth by more than 70 % at 0.1 µM, showing a twelve thousand fold higher effectiveness compared with 1.2 mM chlorhexidine, the oral antiseptic most used by dentists. The minimal inhibitory concentration (MIC) of BisBAL NPs for S. mutans and S. gordonii was 5 µM. MIC of BisBAL NPs for Candida albicans was 10 µM. However, 100 µM of BisBAL NPs were required to interfere with planktonic growth of and biofilm formation by a multi-species population of bacteria. Our experiments show that bactericidal activity of BisBAL NPs was similar to antibiotics such as vancomycin and rifampicin. Based on MTT cell viability assays, we hypothesize that BisBAL NPs potentially act on key enzymes, altering their metabolism, and cause cell lysis. All together, these findings show the efficacy of BisBAL NPs as a broad spectrum antimicrobial agent which could reduce antibiotic usage.

    Plasma protein exudation into the airways is an important pathophysiological event in asthma. The effect of 12 wk of treatment with inhaled fluticasone propionate (FP; 250 microgram twice a day) or salbutamol (Sb; 400 microgram twice a day) on plasma protein leakage was compared in a double-blind, randomized parallel-group study of 30 patients with asthma. Primary outcomes were plasma protein leakage and size selectivity of the blood-airway lumen barrier, cell differentials in BAL fluid, and bronchial responsiveness to histamine (PC20histamine). Two independent procedures to account for the effect of variable dilution of BAL on the levels of albumin (Alb) and alpha2-macroglobulin (A2M) in BAL fluid consisted of correction based on urea levels and on the application of the relative coefficient of excretion [RCE = ([A2M] in BAL fluid/[A2M] in serum)/([Alb] in BAL fluid/[Alb] in serum)]. In the FP group a significant decrease was found in the A2M level and the RCE, and in the percentage of eosinophils in BAL fluid. The PC20histamine increased significantly (mean increase, 2.4 doubling doses), whereas PC20histamine decreased in the Sb group. Differences between groups were significant except for the decrease in eosinophils. We conclude that 12 wk of FP (250 microgram twice a day) decreased the permeability of the blood-airway lumen barrier, in particular for high molecular weight proteins.

    The variability of the broad absorption lines is investigated for a broad absorption line (BAL) QSO, SDSS J022844.09+000217.0 (z = 2.719), with 18 SDSS/BOSS spectra covering 4128 days in the observed frame. With the ratio of the rms spectrum to the mean spectrum, the relative flux change of the BAL-trough is larger than that of the emission lines and the continuum. Fitting the power-law continuum and the emission line profiles of \\civ $\\lambda$1549 and \\siiv$\\lambda$1399, we calculate the equivalent width (EW) for different epochs, as well as the continuum luminosity and the spectral index. It is found that there is a strong correlation between the BAL-trough EW and the spectral index, and a weak negative correlation between the BAL-trough EW and the continuum luminosity. The strong correlation between the BAL-trough EW and the spectral index for this one QSO suggests that dust is intrinsic to outflows. The weak correlation between the BAL variability and the continuum luminosity for this one QSO implies that...

  7. On the origins of C IV absorption profile diversity in broad absorption line quasars

    Baskin, Alexei; Hamann, Fred

    2015-01-01

    There is a large diversity in the C IV broad absorption line (BAL) profile among BAL quasars (BALQs). We quantify this diversity by exploring the distribution of the C IV BAL properties, FWHM, maximum depth of absorption and its velocity shift ($v_{\\rm md}$), using the SDSS DR7 quasar catalogue. We find the following: (i) Although the median C IV BAL profile in the quasar rest-frame becomes broader and shallower as the UV continuum slope ($\\alpha_{\\rm UV}$ at 1700-3000 A) gets bluer, the median individual profile in the absorber rest-frame remains identical, and is narrow (FWHM = 3500 km/s) and deep. Only 4 per cent of BALs have FWHM > 10,000 km/s. (ii) As the He II emission equivalent-width (EW) decreases, the distributions of FWHM and $v_{\\rm md}$ extend to larger values, and the median maximum depth increases. These trends are consistent with theoretical models in which softer ionizing continua reduce overionization, and allow radiative acceleration of faster BAL outflows. (iii) As $\\alpha_{\\rm UV}$ become...

    We present results of our time variability studies of Mg II and Al III absorption lines in a sample of 22 Low Ionization Broad Absorption Line QSOs (LoBAL QSOs) at 0.2 = 1 year) absorption line variability is seen in 8 cases (36% systems) while only 4 of them (i.e 18% systems) show variability over short time-scales (i.e < 1 year). We notice a tendency of highly variable LoBAL QSOs to have high ejection velocity, low equivalent width and low redshift. The detection rate of variability in LoBAL QSOs showing Fe fine-structure lines (FeLoBAL QSOs) is less than that seen in non-Fe LoBAL QSOs. Absorption line variability is more frequently detected in QSOs having continuum dominated by Fe emission lines compared to rest of the QSOs. Confirming these trends with a bigger sample will give vital clues for understanding the physical distinction between different BAL QSO sub-classes. We correlate the absorption line variability with various parameters derived from continuum light curves and find no clear correlation...

  9. Probing the Active Galactic Nuclei using optical spectroscopy

    Vivek, M.

    Variability studies offer one of the best tools for understanding the physical conditions present in regions close to the central engine in an AGN. We probed the various properties of AGN through time variability studies of spectral lines in the optical wavelengths using the 2m telescope in IUCAA Girawali observatory. The absorption line variability studies are mainly concentrated in understanding the nature of outflows in quasars. Quasar outflows have a huge impact on the evolution of central supermassive blackholes, their host galaxies and the surrounding intergalactic medium. Studying the variability in these Broad Absorption Lines (BALs) can help us understand the structure, evolution, and basic physical properties of these outflows. We conducted a repeated Low ionization BAL monitoring program with 27 LoBALs (Low Ionization BALs) at z 0.3-2.1 covering timescales from 3.22 to 7.69 years in the quasar rest frame. We see a variety of phenomena, including some BALs that either appeared or disappeared completely and some BALs which do not vary over the observation period. In one case, the excited fine structure lines have changed dramatically. One source shows signatures of radiative acceleration. Here, we present the results from this program. Emission line studies are concentrated in understanding the peculiar characteristics of a dual-AGN source SDSS J092712.64+294344.0.

    Progressive systemic sclerosis (PSS), or scleroderma, is a disease of unknown etiology that involves many organ systems, including the lungs. The interstitial lung disease of systemic sclerosis is becoming an increasing cause of morbidity and mortality. This process has been previously evaluated with single-site bronchoalveolar lavage (BAL), gallium scanning, pulmonary function testing, and, occasionally, by open lung biopsy. As BAL has been shown to correlate well with open lung biopsy in systemic sclerosis, we sought to determine if single-site BAL accurately reflects alveolitis in a second site in the lung, and if BAL results correlate with other noninvasive tests of lung inflammation: gallium uptake, chest radiography, or arterial blood gas analysis. We performed 17 studies in 13 patients with scleroderma and found no significant lobar differences in lavage results or gallium scanning. By our criteria for normal versus active alveolitis, only two of 17 patient lavages would have been classified as normal by one side and abnormal by the other side. Although percent gallium uptake was equal bilaterally and supported the concept of alveolitis uniformity, gallium uptake intensity did not correlate with activity as measured by BAL. Furthermore, chest radiograph and arterial blood gas analysis did not correlate with BAL results or gallium scanning. We believe these data support the suitability of single-site lavage in the investigation of systemic-sclerosis-associated alveolitis and diminish the importance of gallium scanning in the investigation of systemic sclerosis pulmonary disease.

    Bronchoalveolar lavage (BAL) fluids and serum samples from 153 patients with pulmonary symptoms who were infected with human immunodeficiency virus (HIV) and underwent BAL were examined for the presence of cytomegalovirus (CMV) by conventional culture and by polymerase chain reaction (PCR......) for detection of CMV DNA. PCR detected CMV more frequently than did cultures of BAL fluid (PCR of BAL fluid, 53%; PCR of serum, 40%; and culture, 30%). In a multivariate model, development of extrapulmonary CMV disease was predicted by the finding of CMV in BAL fluid by culture (relative risk [RR], 8.......0; confidence interval [CI], 3.8-16.8) or the finding of CMV DNA in serum (RR, 7.4; CI, 3.2-17.3) or BAL fluid (RR, 8.0; CI, 3.1-20.7) by PCR. Mortality was found to be similar for patients who did or did not have CMV detected by either culture or PCR. Detection of CMV DNA by PCR was a more rapid and sensitive...

    Enzymatic carboligation in a solid/gas bioreactor represents a new challenge in biotechnology. In this paper, the continuous gas-phase production of propioin from two propanal molecules by using thiamine diphosphate-dependent enzymes was studied. Two enzymes were used, namely benzaldehyde lyase (BAL) from Pseudomonas fluorescens and benzoylformate decarboxylase (BFD) from Pseudomonas putida. The enzymes are homologous and catalyze carboligase and carbolyase reactions in which no external cofactor regeneration is needed. The influence of water and substrate activity on the initial reaction rate and biocatalyst stability was investigated. An increase in water activity raised the initial reaction rates to the maximal values of 250 and 80 U g(-1) for BAL and BFD, respectively. The half-life showed the same trend with maximal values of 50 and 78 min for BAL and BFD, respectively. The increase in the half-life by increasing water activity was unexpected. It was also observed that BFD is more stable than BAL in the presence of the substrate propanal. Both enzymes showed substrate inhibition in the kinetic studies, and BAL was also deactivated during the reaction. Unexpectedly, the stereoselectivity of both enzymes (ee of 19 % for BAL and racemic mixture for BFD) was significantly impaired in the gas phase compared to the liquid phase.

    Pathogen-targeted transcriptional profiling in human sputum may elucidate the physiologic state of Mycobacterium tuberculosis (M. tuberculosis) during infection and treatment. However, whether M. tuberculosis transcription in sputum recapitulates transcription in the lung is uncertain. We therefore compared M. tuberculosis transcription in human sputum and bronchoalveolar lavage (BAL) samples from 11 HIV-negative South African patients with pulmonary tuberculosis. We additionally compared these clinical samples with in vitro log phase aerobic growth and hypoxic non-replicating persistence (NRP-2). Of 2179 M. tuberculosis transcripts assayed in sputum and BAL via multiplex RT-PCR, 194 (8.9%) had a p-value <0.05, but none were significant after correction for multiple testing. Categorical enrichment analysis indicated that expression of the hypoxia-responsive DosR regulon was higher in BAL than in sputum. M. tuberculosis transcription in BAL and sputum was distinct from both aerobic growth and NRP-2, with a range of 396-1020 transcripts significantly differentially expressed after multiple testing correction. Collectively, our results indicate that M. tuberculosis transcription in sputum approximates M. tuberculosis transcription in the lung. Minor differences between M. tuberculosis transcription in BAL and sputum suggested lower oxygen concentrations or higher nitric oxide concentrations in BAL. M. tuberculosis-targeted transcriptional profiling of sputa may be a powerful tool for understanding M. tuberculosis pathogenesis and monitoring treatment responses in vivo.

    Oxidative stress and lung injury induced by short-term exposure to wood smoke were evaluated in guinea pigs through cell profile, bronchoalveolar lavage (BAL), conventional histology and immunohistochemistry (4-hydroxynonenal, 3-nitrotyrosine, Mn-superoxide dismutase, heme oxygenase-1); malondialdehyde and 4-hydroxynonenal concentration, Mn-superoxide dismutase, glutathione reductase, glutathione peroxidase, and catalase activities in plasma, lung and BAL. Total cells increased in BAL, and the percentage of macrophages, neutrophils and lymphocytes augmented (72-96 h). Histopathological examination of lung tissues showed mild thickening of membranous bronchiole walls, infiltration of foamy macrophages and polymorphonuclear leukocytes in bronchial, bronchiolar and intraalveolar spaces. Goblet cell hyperplasia was also observed in bronchial and bronchiolar epithelia. Plasma malondialdehyde concentration was increased at all times, while 4-hydroxynonenal was increased only in plasma and BAL after 24 h. Plasma glutathione reductase activity increased at 24 and 72 h, BAL glutathione peroxidase activity decreased at 72 and 96 h, whereas catalase activity increased in plasma at 72 h, and decreased in BAL at 24 h. Immunostaining intensity to 4-hydroxynonenal, 3-nitrotyrosine, Mn-superoxide dismutase and heme oxygenase-1 was enhanced mainly in macrophages, bronchial/bronchiolar epithelial cells and type II pneumocytes after 72-96 h of wood smoke exposure. Overall, short-term exposure to wood smoke induces alterations in oxidative/antioxidant state in lung and airway injury, similar to those observed in humans with domestic exposure.

    The massive depletion of gastrointestinal-tract CD4 T cells is a hallmark of the acute phase of HIV infection. In contrast, the depletion of the lower-respiratory-tract mucosal CD4 T cells as measured in bronchoalveolar lavage (BAL) fluid is more moderate and similar to the depletion of CD4 T cells observed in peripheral blood (PB). To understand better the dynamics of disease pathogenesis and the potential for the reconstitution of CD4 T cells in the lung and PB following the administration of effective antiretroviral therapy, we studied cell-associated viral loads, CD4 T-cell frequencies, and phenotypic and functional profiles of antigen-specific CD4 T cells from BAL fluid and blood before and after the initiation of highly active antiretroviral therapy (HAART). The major findings to emerge were the following: (i) BAL CD4 T cells are not massively depleted or preferentially infected by HIV compared to levels for PB; (ii) BAL CD4 T cells reconstitute after the initiation of HAART, and their infection frequencies decrease; (iii) BAL CD4 T-cell reconstitution appears to occur via the local proliferation of resident BAL CD4 T cells rather than redistribution; and (iv) BAL CD4 T cells are more polyfunctional than CD4 T cells in blood, and their functional profile is relatively unchanged after the initiation of HAART. Taken together, these data suggest mechanisms for mucosal CD4 T-cell depletion and interventions that might aid in the reconstitution of mucosal CD4 T cells. PMID:20610726

    Azole resistance in Aspergillus fumigatus is increasingly reported. Here, we describe the validation of the AsperGenius, a new multiplex real-time PCR assay consisting of two multiplex real-time PCRs, one that identifies the clinically relevant Aspergillus species, and one that detects the TR34, L98H, T289A, and Y121F mutations in CYP51A and differentiates susceptible from resistant A. fumigatus strains. The diagnostic performance of the AsperGenius assay was tested on 37 bronchoalveolar lavage (BAL) fluid samples from hematology patients and 40 BAL fluid samples from intensive care unit (ICU) patients using a BAL fluid galactomannan level of ≥1.0 or positive culture as the gold standard for detecting the presence of Aspergillus. In the hematology and ICU groups combined, there were 22 BAL fluid samples from patients with invasive aspergillosis (IA) (2 proven, 9 probable, and 11 nonclassifiable). Nineteen of the 22 BAL fluid samples were positive, according to the gold standard. The optimal cycle threshold value for the presence of Aspergillus was Aspergillus species and 14 A. fumigatus samples). This resulted in a sensitivity, specificity, and positive and negative predictive values of 88.9%, 89.3%, 72.7%, and 96.2%, respectively, for the hematology group and 80.0%, 93.3%, 80.0%, and 93.3%, respectively, in the ICU group. The CYP51A real-time PCR confirmed 12 wild-type and 2 resistant strains (1 TR34-L98H and 1 TR46-Y121F-T289A mutant). Voriconazole therapy failed for both patients. The AsperGenius multiplex real-time PCR assay allows for sensitive and fast detection of Aspergillus species directly from BAL fluid samples. More importantly, this assay detects and differentiates wild-type from resistant strains, even if BAL fluid cultures remain negative.

    Bismuth nanoparticles have many interesting properties to be applied in biomedical and medicinal sectors, however their safety in humans have not been comprehensively investigated. The objective of this research was to determine the cytotoxic effect of bismuth dimercaptopropanol nanoparticles (BisBAL NPs) on epithelial cells. The nanoparticles are composed of 18.7 nm crystallites on average and have a rhombohedral structure, agglomerating into chains-like or clusters of small nanoparticles. Based on MTT viability assay and fluorescence microscopy, cytotoxicity was not observed on monkey kidney cells after growing with 5 µM of BisBAL NPs for 24 h. Employing same techniques, identical results were obtained with human epithelial cells (HeLa), showing a not strain-dependent phenomenon. The absence of toxic effects on epithelial cells growing with BisBAL NPs was corroborated with long-time experiments (24-72 hrs.), showing no difference in comparison with growing control (cells without nanoparticles). Further, genotoxicity assays, comet assay and fluorescent microscopy and electrophoresis in bromide-stained agarose gel revealed no damage to genomic DNA of MA104 cells after 24 h. of exposition to BisBAL NPs. Finally, the effect of bismuth nanoparticles on protein synthesis was studied in cells growing with BisBAL NPs for 24 h. SDS-PAGE assays showed no difference between treated and untreated cells, suggesting that BisBAL NPs did not interfere with protein synthesis. Hence BisBAL NPs do not appear to exert cytotoxic effects suggesting their biological compatibility with epithelial cells.

    A microinstillation technique of inhalation exposure was utilized to assess lung injury following chemical warfare nerve agent VX [methylphosphonothioic acid S-(2-[bis(1-methylethyl)amino]ethyl) O-ethyl ester] exposure in guinea pigs. Animals were anesthetized using Telazol-meditomidine, gently intubated, and VX was aerosolized using a microcatheter placed 2 cm above the bifurcation of the trachea. Different doses (50.4 microg/m3, 70.4 micro g/m(m3), 90.4 microg/m(m3)) of VX were administered at 40 pulses/min for 5 min. Dosing of VX was calculated by the volume of aerosol produced per 200 pulses and diluting the agent accordingly. Although the survival rate of animals exposed to different doses of VX was similar to the controls, nearly a 20% weight reduction was observed in exposed animals. After 24 h of recovery, the animals were euthanized and bronchoalveolar lavage (BAL) was performed with oxygen free saline. BAL was centrifuged and separated into BAL fluid (BALF) and BAL cells (BALC) and analyzed for indication of lung injury. The edema by dry/wet weight ratio of the accessory lobe increased 11% in VX-treated animals. BAL cell number was increased in VX-treated animals compared to controls, independent of dosage. Trypan blue viability assay indicated an increase in BAL cell death in 70.4 microg/m(m3) and 90.4 microg/m(m3) VX-exposed animals. Differential cell counting of BALC indicated a decrease in macrophage/monocytes in VX-exposed animals. The total amount of BAL protein increased gradually with the exposed dose of VX and was highest in animals exposed to 90.4 microg/m(m3), indicating that this dose of VX caused lung injury that persisted at 24 h. In addition, histopathology results also suggest that inhalation exposure to VX induces acute lung injury.

    Objective To establish a novel bioartificial liver (BAL) consisting of spheroids of porcine hepatocytes in a hollow-fiber bioreactor, and to perform an in vitro study on its metabolic effects on the serum from severe hepatitis B patients.Methods Hepatocytes were isolated from pup pigs and cultured as aggregate spheroids through rotation and vibration. Phase-contrast microscopy, transmission electron microscopy, and scanning electron microscopy were used for morphological detection of hepatocyte spheroids. The hepatocyte spheroids were then transferred into the shell of a polysulfone hollow-fiber bioreactor, creating a novel BAL. Diluted serum samples of severe hepatitis B patients were circulated for 3 hours each into the bioreactor, by using an extracorporeal circulatory system. Every half hour, including both before and after perfusion, serum samples were collected to assay total bilirubin (TBIL), total protein (TP), albumin (ALB), and globulin (GLB) concentrations in order to judge the metabolic effects of this novel BAL. Results Most hepatocytes had formed spheroids with high viability after 24 hours in culture. After 3 hours of perfusion, when compared with the control group, the serum concentration of TBIL in the treatment group decreased significantly (P<0.01), but the serum concentrations of TP and ALB increased significantly (P<0.05). Conclusions Hepatocytes can be conveniently cultured as aggregate spheroids through a rotation and vibration method. The novel BAL is efficient in removing bilirubin from the serum of severe hepatitis B patients, and in supplying the serum with ALB. Thus, the BAL might provide effective therapy for patients with severe hepatitis B.The extracorporeal bioartificial liver support system (EBLSS) has been established to compensate for hepatic function in patients with severe hepatopathy, and to provide supportive therapy for these patients. EBLSS has an important status in the research of artificial organs. At present, the study

    Fiber bronchoscopy under local anaesthesia is an examination procedure frequently employed in the remainder of Scandinavia, Europe and USA. It requires only few resources and the costs are considerably less than fiber bronchoscopy under general anaesthesia. Bronchoalveolar lavage (BAL) in connection with fiber bronchoscopy is rapidly undertaken but analysis of the material obtained requires considerable time. A method of induction of local anaesthesia, performance of BAL and preparation of the washings obtained is described. Fiber bronchoscopy and BAL are considered to be safe examination procedures in patients with mild asthma in a stable phase. The examination is only associated with slight discomfort for the patients, who will frequently accept repeated investigations, and complications are rare. BAL is a valuable examination procedure in research and the results have increased the knowledge of mechanisms in a series of interstitial pulmonary diseases. Future investigations of the humoral and cellular components in BAL fluid in asthmatic patients will contribute to increase knowledge of the pathological mechanisms in asthmatic disease.

    2014-01-01

    We have monitored 12 intrinsic narrow absorption lines (NALs) in five quasars and seven mini-broad absorption lines (mini-BALs) in six quasars for a period of 4-12 years (1-3.5 years in the quasar rest-frame). We present the observational data and the conclusions that follow immediately from them, as a prelude to a more detailed analysis. We found clear variability in the equivalent widths (EWs) of the mini-BAL systems but no easily discernible changes in their profiles. We did not detect any variability in the NAL systems nor in narrow components that are often located at the center of mini-BAL profiles. Variations in mini-BAL EWs are larger at longer time intervals, reminiscent of the trend seen in variable broad absorption lines. If we assume that the observed variations result from changes in the ionization state of the mini-BAL gas, we infer lower limits to the gas density $\\sim$ 10$^3$-10$^5$ cm$^{-3}$ and upper limits on the distance of the absorbers from the central engine of order a few kpc.

    We report the discovery of excess broad band absorption near 2250 A (EBBA) in the spectra of seven broad absorption line (BAL) quasars. By comparing with the statistical results from the control quasar sample, the significance for the detections are all above the > 4{\\sigma} level, with five above > 5{\\sigma}. The detections have also been verified by several other independent methods. The EBBAs present broader and weaker bumps at smaller wavenumbers than the Milky Way, and similar to the Large Magellanic Cloud. The EBBA bump may be related to the 2175 A bump seen in the Local Group and may be a counterpart of the 2175 A bump under different conditions in the early Universe. Furthermore, five objects in this sample show low-ionization broad absorption lines (LoBALs), such as Mg II and Al III, in addition to the high-ionization broad absorption lines (HiBALs) of C IV and Si IV. The fraction of LoBALs in our sample, ~70%, is surprisingly high compared to that of general BAL quasars, ~10%. Although the origin of...

    We present the results of recent Chandra, XMM-Newton, and Hubble Space Telescope observations of the radio-loud (RL), broad absorption line (BAL) quasar PG 1004+130. We compare our new observations to archival X-ray and UV data, creating the most comprehensive, high signal-to-noise, multi-epoch, spectral monitoring campaign of a RL BAL quasar to date. We probe for variability of the X-ray absorption, the UV BAL, and the X-ray jet, on month-year timescales. The X-ray absorber has a low column density of $N_{H}=8\\times10^{20}-4\\times10^{21}$ cm$^{-2}$ when it is assumed to be fully covering the X-ray emitting region, and its properties do not vary significantly between the 4 observations. This suggests the observed absorption is not related to the typical "shielding gas" commonly invoked in BAL quasar models, but is likely due to material further from the central black hole. In contrast, the CIV BAL shows strong variability. The equivalent width (EW) in 2014 is EW=11.24$\\pm$0.56 \\AA, showing a fractional increa...

    Objective: To report 4 cases of biphenotypic acute leukemia (BAL) with t(8;21)(q22;q22), and analyze the characteristics of morphology, immune phenotype, chromosome karyotype (MIC) and clinical manifestations. Methods: The BAL patients with t(8;21)(q22;q22) (group A) were compared with the randomly selected BAL patients with other clonical chromosomal changes (group B) and acute myeloid leukemia M2 cases with t(8;21)(q22;q22) (group C)in MIC and clinical features.Results: BAL with t(8;21)(q22;q22) showed acute myeloid leukemia with high percentages of blast cells morphologically;revealed co-positive to B-lymphoid and myeloid lineages, frequent and high expressions of CD34 and CD33; were responsive to chemotherapy for myeloid and lymphocytic leukemia simultaneously well. Conclusion: A new subset of BAL with t(8;21)(q22;q22) was reported, and this suggests that the leukemia colony with t(8;21)(q22;q22) might originate from early phase of hematopoiesis.

    We consider how the profile and multi-year variability properties of a large sample of C IV Broad Absorption Line (BAL) troughs change when BALs from Si IV and/or Al III are present at corresponding velocities, indicating that the line of sight intercepts at least some lower ionization gas. We derive a number of observational results for C IV BALs separated according to the presence or absence of accompanying lower ionization transitions, including measurements of composite profile shapes, equivalent width (EW), characteristic velocities, composite variation profiles, and EW variability. We also measure the correlations between EW and fractional-EW variability for C IV, Si IV, and Al III. Our measurements reveal the basic correlated changes between ionization level, kinematics, and column density expected in accretion-disk wind models; e.g., lines of sight including lower ionization material generally show deeper and broader C IV troughs that have smaller minimum velocities and that are less variable. Many C IV BALs with no accompanying Si IV or Al III BALs may have only mild or no saturation.

  7. Effect of Lipophilic Bismuth Nanoparticles on Erythrocytes

    Full Text Available Lipophilic bismuth dimercaptopropanol nanoparticles (BisBAL NPs have a very important antimicrobial activity; however their effect on human cells or tissues has not been completely studied. Undesirable effects of bismuth include anemia which could result from suicidal erythrocyte death or eryptosis. The objective of this research was to determine the effect of bismuth dimercaptopropanol nanoparticles on blood cells. The nanoparticles are composed of 53 nm crystallites on average and have a spherical structure, agglomerating into clusters of small nanoparticles. Based on cell viability assays and optical microscopy, cytotoxicity on erythrocytes was observed after growing with 500 and 1000 µM of BisBAL NPs for 24 h. AM Calcein was retained inside erythrocytes when they were exposed to 100 µM (or lower concentrations of BisBAL NPs for 24 h, suggesting the absence of damage in plasmatic membrane. Genotoxic assays revealed no damage to genomic DNA of blood cells after 24 h of exposition to BisBAL NPs. Finally, 100–1000 µM of bismuth nanoparticles promotes apoptosis between blood cells after 24 h of incubation. Hence BisBAL NPs at concentrations lower than 100 µM do not cause damage on blood cells; they could potentially be used by humans without affecting erythrocytes and leukocytes.

    Twenty-three cats with respiratory signs who had domiciliary contact with cats with sporotrichosis were studied. Sneezing was the predominant extracutaneous sign. Twelve cats had no skin lesions and 11 had ulcerated skin lesions. Mycological culture of material obtained from the nasal cavity, oral cavity, bronchoalveolar lavage (BAL) and skin lesions, when present, was performed for all cats. In the case of autopsy, lung fragments were cultured. Sporothrix schenckii was isolated from four of the 12 cats without skin lesions: BAL (one cat) and oral and/or nasal cavity (three cats). The latter three animals developed nasal and distant skin lesions within the following 2-4 weeks. The cat with S. schenckii isolated from BAL did not develop skin lesions or lower respiratory tract symptoms during the 6 months of follow-up. S. schenckii was isolated from one or more biological samples of all 11 cats with skin lesions: oral cavity (five), nasal cavity (eight), BAL fluid (four), skin lesions (eight), and blood culture (one). No yeast-like structures were observed upon BAL cytology in any of the 23 cats. The results suggest that S. schenckii can cause infection of skin contiguous to the natural facial orifices through colonisation of the mucosal surfaces of the upper airways.

    We report the discovery in the Sloan Digital Sky Survey and the SDSS-III Baryon Oscillation Spectroscopic Survey of seventeen broad absorption line (BAL) quasars with high-ionization troughs that include absorption redshifted relative to the quasar rest frame. The redshifted troughs extend to velocities up to v=12,000 km/s and the trough widths exceed 3000 km/s in all but one case. Approximately 1 in 1000 BAL quasars with blueshifted C IV absorption also has redshifted C IV absorption; objects with C IV absorption present only at redshifted velocities are roughly four times rarer. In more than half of our objects, redshifted absorption is seen in C II or Al III as well as C IV, making low-ionization absorption at least ten times more common among BAL quasars with redshifted troughs than among standard BAL quasars. However, the C IV absorption equivalent widths in our objects are on average smaller than those of standard BAL quasars with low-ionization absorption. We consider several possible ways of generatin...

    Benzaldehyde lyase (BAL, EC 4.1.2.38) from Pseudomonas fluorescens and benzoylformate decarboxylase (BFD, EC 4.1.1.7) from Pseudomonas putida are thiamine diphosphate-dependent enzymes. These enzymes share a common tetrameric structure and catalyze various C--C-bond forming and breaking reactions. Here we describe a detailed study of the asymmetric synthesis of propioin from propanal catalyzed by BAL or BFD in aqueous solution in a batch reactor. Both enzymes are deactivated in the presence of high concentration of propanal. Compared to BAL, BFD is more stable under reaction conditions as well as during storage. The kinetic studies showed a typical Michaelis-Menten kinetic for BAL with a maximal specific reaction rate of 26.2 U/mg and an unusually high K(M) of 415 mM, whereas the v/[S]-plot for BFD is almost linear in the concentration range (100-1500 mM) investigated. Both enzymes produce propioin with opposite enantiomeric excess: BAL produced the (S)-propioin (ee of 35%), whereas BFD yielded the (R)-enantiomer (ee of 67%).

    Airborne particulate matter (PM) is hypothesized to play a role in increases in asthma prevalence, although a causal relationship has yet to be established. To investigate the effects of real-world PM exposure on airway reactivity (AHR) and bronchoalveolar lavage (BAL) cellularity, mice were exposed to a single dose (0.5 mg/ mouse) of ambient PM, coal fly ash, or diesel PM. It was found that ambient PM exposure induced increases in AHR and BAL cellularity, whereas diesel PM induced significant increases in BAL cellularity, but not AHR. On the other hand, coal fly ash exposure did not elicit significant changes in either of these parameters. Ambient PM-induced temporal changes in AHR, BAL cells, and lung cytakine levels over a 2-wk period were then examined. Ambient PM-induced AHR was sustained over 7 d. The increase in AHR was preceded by dramatic increases in BAL eosinophils, whereas a decline in AHR was associated with increases in macrophages. It is concluded that ambient PM can induce asthmalike parameters in mice, suggesting that PM exposure may be an important factor in increases in asthma prevalence.

    Full Text Available Generally, all traits of economic importance should be included in the breeding goal of livestock breeding programmes. The main aim of this study was to examine economic values for a combination of dairy and meat traits of the dual purpose Bardhoka (BAR, Balusha (BAL, Sharri (SHA and Kosova (KOS sheep breeds in Kosovo. The underlying herd model is based on a deterministic approach considering a sheep flock with milk production, lamb fattening and replacement stock. In order to examine the economic impact for different sheep breeds, the production traits considered were milk (milk yield and fattening (daily gain. For each lactation cycle among the breeds the main revenues resulted from selling milk (€ 61.82/46.03/26.37/27.22 and fattened lambs (€ 34.06/39.88/35.42/33.92 for BAR/BAL/ SHA/KOS, respectively. For BAR and BAL the economic value per average ewe place and year was € 37.7 for both breeds, while for SHA and KOS it was € 35.1 and € 32.5, respectively. For lamb fattening, daily gain was found to have the highest economic value at € 7.00 for BAL, SHA and KOS, while for BAR it was € 6.67. The relative economic values for milk yield and daily gain for BAR, BAL, SHA and KOS were 84.96:15.04, 84.42:15.58, 83.45:16.55, and 82.36:17.64, respectively.

    We conducted radio detection observations at 8.4 GHz for 22 radio-loud broad absorption line (BAL) quasars, selected from the Sloan Digital Sky Survey (SDSS) Third Data Release, by a very-long-baseline interferometry (VLBI) technique. The VLBI instrument we used was developed by the Optically ConnecTed Array for VLBI Exploration project (OCTAVE), which is operated as a subarray of the Japanese VLBI Network (JVN). We aimed at selecting BAL quasars with nonthermal jets suitable for measuring their orientation angles and ages by subsequent detailed VLBI imaging studies to evaluate two controversial issues of whether BAL quasars are viewed nearly edge-on, and of whether BAL quasars are in a short-lived evolutionary phase of quasar population. We detected 20 out of 22 sources using the OCTAVE baselines, implying brightness temperatures greater than 10^5 K, which presumably come from nonthermal jets. Hence, BAL outflows and nonthermal jets can be generated simultaneously in these central engines. We also found four...

    Pneumonia in patients with organ transplantation constitutes a very frequent cause of mortality, as a result precocious aetiologic diagnosis is indispensable. The bronchoscopic techniques, bronchoalveolar lavage (BAL) and transbronchial biopsy (TBB), constitute fundamental procedures for these diagnoses. We begin this study with the aim of evaluating the profitability obtained with these procedures. 36 bronchoscopies were performed on 29 patients with organ transplantation, in all of them we realized BAL and in 20 TBB. We confirm the presence of pneumonia in 30 (in 15 of them we had performed TBB), the BAL was diagnostic in 20 cases (66.6%) and the TBB in 7 (46.6%). With both, BAL and TBB, we obtained a sensitivity of 80% and a specificity of 75%. We isolated 10 bacteria, 8 Citomegalovirus (CMV), 6 Pneumocystis carinii and 2 Aspergillus fumigatus. The BAL and the TBB contributed significantly in the aetiologic diagnosis of pneumonia in patients with organ transplantation, consequently we consider them basic tools in the management of these infections.

    Exposure to wood dust within the woodworking industry has been shown to cause a variety of respiratory disorders. The aim of this study was to investigate the cellular effects in bronchoalveolar lavage (BAL) fluid and peripheral blood from healthy individuals exposed to pinewood dust. Eleven healthy volunteers were exposed to pinewood dust for 1 h in a whole-body exposure chamber. BAL fluid and blood cells were differentially counted and the expression of activation, adhesion and subset markers on alveolar macrophages and T-lymphocytes was determined 2-6 weeks before and 20 h after the exposure. Following pinewood dust exposure, the total BAL fluid cell concentration increased from 81.4 (64.1-97.5) x 10(6) cells x L(-1) (median (interquartile range)) to 195.3 (154.6-341.2) x 10(6) cells x L(-1). The BAL fluid T-lymphocyte concentration increased from 3.8% (3.5-6.5%) to 7.6% (4.9-11.2%), and BAL fluid eosinophil concentration from 0.0% (0.0-0.2%) to 1.8% (0.6-3.5%). Inhalation of pinewood dust leads to the recruitment of inflammatory cells to the airways of healthy individuals. The increase in numbers of eosinophils, T-lymphocytes and mast cells, i.e. cells of crucial importance to airway inflammation, in the lungs may be related to the increased risk of developing respiratory disorders among woodworkers.

    Biphenotypic acute leukaemia (BAL) represents about 5% of adult acute leukaemia. Based on a previously described scoring system, the European Group for Immunologic Classification of Leukaemia (EGIL) proposed a set of diagnostic criteria for BAL. This scoring system is based on the number and degree of the specificity of several markers for myeloid or T/B lymphoid blasts. Here, we report the case of a BAL with Burkitt-like cytology, corresponding to "the acute lymphoblastic leukaemia, Burkitt type" L3 for the FAB classification. By flow cytometry, the blasts showed a positivity for B lymphoid cytoplasmic (CD79a and mu) and membrane (CD19, CD22, CD24, IgM) markers AND a positivity for the myeloid (CD13, CD33, CD65, CD15) markers.

Fourteen cats were individually inoculated with 800 third stage larvae of A. abstrusus and five non-infected cats lined as a control group. The BAL procedure was performed through the use of an endotracheal tube on the nineteen cats with a mean age of 18 months, on 0, 30, 60, 90, 120, 180 and 270 days after infection. Absolute cell counts in the infected cats revealed that alveolar macrophages and eosinophils were the predominant cells following infection. This study shows that the technique allows us to retrieve cells and first stage larvae what provides information about the inflammatory process caused by aelurostrongylosis.

    Kaposi's sarcoma (KS) is the most frequent AIDS-associated neoplasm, and often disseminates to visceral organs, including the lungs. An ante-mortem diagnosis of pulmonary KS is difficult. Recently, DNA sequences resembling a new human herpes virus (HHV-8), have been identified in various forms...... of KS. We hypothesized that these sequences are present in samples obtained by bronchoalveolar lavage (BAL) in patients with pulmonary KS. Utilizing a nested polymerase chain reaction (PCR), 7/12 BAL cell samples from HIV-infected patients with endobronchial KS were positive for HHV-8 DNA. In contrast......, only 2/39 samples from HIV-infected patients without evidence of KS were positive (p = 0.007). Detection of HHV-8 in BAL cells of patients with pulmonary KS was highly specific (95%), with a sensitivity of 58% and a positive predictive value of 78%. In conclusion, HHV-8 is associated with pulmonary KS...

    Full Text Available Abstract Bronchoalveolar lavage (BAL is a useful diagnostic tool in interstitial lunge diseases (ILD. However, differential cell counts are often non specific and immunocytochemistry is time consuming. Staining of glyoproteins by periodic acid Schiff (PAS reaction may help in discriminating different forms of ILD. In addition, PAS staining is easy to perform. BAL cells from patients with idiopathic pulmonary fibrosis (IPF (n = 8, sarcoidosis (n = 9, and extrinsic allergic alveolitis (EAA (n = 2 were investigated. Cytospins from BAL cells were made and cells were stained using Hemacolor quick stain and PAS staining. Lymphocytic alveolitis was found in sarcoidosis and EAA whereas in IPF both lymphocytes and neutrophils were increased. PAS positive cells were significantly decreased in EAA compared to IPF and sarcoidosis (25.5% ± 0.7% vs 59.8% ± 25.1% and 64.0% ± 19.7%, respectively (P

    1987-01-01

    Spectrophotometric observations of six broad absorption-line QSOs (BALQSOs) are presented. The continua and emission lines are compared with those in the spectra of QSOs without BALs. A statistically significant difference is found in the emission-line intensity ratio for (N V 1240-A)/(C IV 1549-A). The median value of (N V)/(C IV) for the BALQSOs is two to three times the median for QSOs without BALs. The absorption features of the BALQSOs are described, and the column densities and limits on the ionization structure of the BAL region are discussed. If the dominant ionization mechanism is photoionization, then it is likely that either the ionizing spectrum is steep or the abundances are considerably different from solar. Collisional ionization may be a significant factor, but it cannot totally dominate the ionization rate.

  6. Modeling the chelation of As(III) in lewisite by dithiols using density functional theory and solvent-assisted proton exchange.

    Harper, Lenora K; Bayse, Craig A

    2015-12-01

    Dithiols such as British anti-lewisite (BAL, rac-2,3-dimercaptopropanol) are an important class of antidotes for the blister agent lewisite (trans-2-chlorovinyldichloroarsine) and, more generally, are chelating agents for arsenic and other toxic metals. The reaction of the vicinal thiols of BAL with lewisite through the chelation of the As(III) center has been modeled using density functional theory (DFT) and solvent-assisted proton exchange (SAPE), a microsolvation method that uses a network of water molecules to mimic the role of bulk solvent in models of aqueous phase chemical reactions. The small activation barriers for the stepwise SN2-type nucleophilic attack of BAL on lewisite (0.7-4.9kcal/mol) are consistent with the favorable leaving group properties of the chloride and the affinity of As(III) for soft sulfur nucleophiles. Small, but insignificant, differences in activation barriers were found for the initial attack of the primary versus secondary thiol of BAL and the R vs S enantiomer. An examination of the relative stability of various dithiol-lewisite complexes shows that ethanedithiols like BAL form the most favorable chelation complexes because the angles formed in five-membered ring are most consistent with the hybridization of As(III). More obtuse S-As-S angles are required for larger chelate rings, but internal As⋯N or As⋯O interactions can enhance the stability of moderate-sized rings. The low barriers for lewisite detoxification by BAL and the greater stability of the chelation complexes of small dithiols are consistent with the rapid reversal of toxicity demonstrated in previously reported animal models.

    The main aim of the present study was to assess the early diagnostic value of bronchoalveolar lavage (BAL) in radiation-induced lung injury in patients with breast carcinoma. Twenty-six females receiving postoperative radiotherapy for breast cancer were evaluated before and 0, 15, 30, 60 , and 180 days after radiotherapy. History, physical examination, chest radiographs, and pulmonary function tests were obtained. BAL, including lymphocyte subsets analysis, was limited to the second evaluation after radiotherapy. A group of 21 healthy females were used as control. Findings after radiotherapy in asymptomatic patients were compared with findings in a group of patients with radiation pneumonitis. Irradiated patients showed a significantly (p<0.01) greater percentage (29.5{+-}15.7%) of BAL lymphocytes than controls (6.2{+-}3.3%). No statistical differences existed in BAL findings between the irradiated and unirradiated sides of the chest. Percentages of BAL lymphocytes did not differ significantly between patients who developed subsequent pneumonitis (24.5{+-}13.5%) and those who did not develop pneumonitis (32.8{+-}16.5%). Patients with pneumonitis at the time of BAL had significantly higher (p<0.05) alveolar CD4 subset cells (24.8{+-}10.2%) than asymptomatic patients (15.2{+-}8.9%). Maximal reductions in total lung capacity (p<0.01), and residual volume (p<0.05) occurred 60 days after irradiation. The early lymphocytic alveolitis induced by unilateral thoracic radiotherapy in most patients with breast cancer is always bilateral and does not predict the subsequent development of radiological evidence of pneumonitis.

    Full Text Available Legionella is a gram-negative bacterium that can cause Pontiac fever, a mild upper respiratory infection and Legionnaire’s disease, a more severe illness. We aimed to compare the performance of urine antigen, culture and PCR test methods and to determine if sputum is an alternative to the use of more invasive bronchoalveolar lavage (BAL. Data for this study included specimens tested for Legionella at PHOL from January 1, 2010 to April 30, 2014, as part of routine clinical testing. We found sensitivity of UAT compared to culture to be 87%, specificity 94.7%, positive predictive value (PPV 63.8% and negative predictive value (NPV 98.5%. Sensitivity of UAT compared to PCR was 74.7%, specificity 98.3%, PPV 77.7% and NPV 98.1%. Of 146 patients who had a Legionella positive result by PCR, only 66(45.2% also had a positive result by culture. Sensitivity for culture was the same using either sputum or BAL (13.6%; sensitivity for PCR was 10.3% for sputum and 12.8% for BAL. Both sputum and BAL yield similar results despite testing methods (Fisher Exact p-values=1.0, for each test. In summary, all test methods have inherent weaknesses in identifying Legionella; thereforemore than one testing method should be used. Obtaining a single specimen type from patients with pneumonia limits the ability to diagnose Legionella, particularly when urine is the specimen type submitted. Given ease of collection, and similar sensitivity to BAL, clinicians are encouraged to submit sputum in addition to urine when BAL submission is not practical, from patients being tested for Legionella.

    Full Text Available Abstract Background Our institute has developed a novel bio-artificial liver (BAL support system, based on a multi-layer radial-flow bioreactor carrying porcine hepatocytes and mesenchymal stem cells. It has been shown that porcine hepatocytes are capable of carrying infectious porcine endogenous retroviruses (PERVs into human cells, thus the microbiological safety of any such system must be confirmed before clinical trials can be performed. In this study, we focused on assessing the status of PERV infection in beagles treated with the novel BAL. Methods Five normal beagles were treated with the novel BAL for 6 hours. The study was conducted for 6 months, during which plasma was collected from the BAL and whole blood from the beagles at regular intervals. DNA and RNA in both the collected peripheral blood mononuclear cells (PBMCs and plasma samples were extracted for conventional PCR and reverse transcriptase (RT-PCR with PERV-specific primers and the porcine-specific primer Sus scrofa cytochrome B. Meanwhile, the RT activity and the in vitro infectivity of the plasma were measured. Results Positive PERV RNA and RT activity were detected only in the plasma samples taken from the third circuit of the BAL system. All other samples including PBMCs and other plasma samples were negative for PERV RNA, PERV DNA, and RT activity. In the in vitro infection experiment, no infection was found in HEK293 cells treated with plasma. Conclusions No infective PERV was detected in the experimental animals, thus the novel BAL had a reliable microbiological safety profile.

    Metabolomics protocols are used to comprehensively characterize the metabolite content of biological samples by exploiting cutting-edge analytical platforms, such as gas chromatography (GC) or liquid chromatography (LC) coupled to mass spectrometry (MS) assays, as well as nuclear magnetic resonance (NMR) assays. We have developed novel sample preparation procedures combined with GC-MS, LC-MS, and NMR metabolomics profiling for analyzing bronchial wash (BW) and bronchoalveolar lavage (BAL) fluid from 15 healthy volunteers following exposure to biodiesel exhaust and filtered air. Our aim was to investigate the responsiveness of metabolite profiles in the human lung to air pollution exposure derived from combustion of biofuels, such as rapeseed methyl ester biodiesel, which are increasingly being promoted as alternatives to conventional fossil fuels. Our multi-platform approach enabled us to detect the greatest number of unique metabolites yet reported in BW and BAL fluid (82 in total). All of the metabolomics assays indicated that the metabolite profiles of the BW and BAL fluids differed appreciably, with 46 metabolites showing significantly different levels in the corresponding lung compartments. Furthermore, the GC-MS assay revealed an effect of biodiesel exhaust exposure on the levels of 1-monostearylglycerol, sucrose, inosine, nonanoic acid, and ethanolamine (in BAL) and pentadecanoic acid (in BW), whereas the LC-MS assay indicated a shift in the levels of niacinamide (in BAL). The NMR assay only identified lactic acid (in BW) as being responsive to biodiesel exhaust exposure. Our findings demonstrate that the proposed multi-platform approach is useful for wide metabolomics screening of BW and BAL fluids and can facilitate elucidation of metabolites responsive to biodiesel exhaust exposure.

    Lewisite is a potent chemical warfare arsenical vesicant that can cause severe skin lesions. Today, lewisite exposure remains possible during demilitarization of old ammunitions and as a result of deliberate use. Although its cutaneous toxicity is not fully elucidated, a specific antidote exists, the British anti-lewisite (BAL, dimercaprol) but it is not without untoward effects. Analogs of BAL, less toxic, have been developed such as meso-2,3-dimercaptosuccinic acid (DMSA) and have been employed for the treatment of heavy metal poisoning. However, efficacy of DMSA against lewisite-induced skin lesions remains to be determined in comparison with BAL. We have thus evaluated in this study the therapeutic efficacy of BAL and DMSA in two administration modes against skin lesions induced by lewisite vapor on SKH-1 hairless mice. Our data demonstrate a strong protective efficacy of topical application of dimercapto-chelating agents in contrast to a subcutaneous administration 1h after lewisite exposure, with attenuation of wound size, necrosis and impairment of skin barrier function. The histological evaluation also confirms the efficacy of topical application by showing that treatments were effective in reversing lewisite-induced neutrophil infiltration. This protective effect was associated with an epidermal hyperplasia. However, for all the parameters studied, BAL was more effective than DMSA in reducing lewisite-induced skin injury. Together, these findings support the use of a topical form of dimercaprol-chelating agent against lewisite-induced skin lesion within the first hour after exposure to increase the therapeutic management and that BAL, despite its side-effects, should not be abandoned.

    Full Text Available Macrophage migration inhibitory factor (MIF is an inflammatory cytokine associated with acute and chronic inflammatory disorders and corticosteroid insensitivity. Its expression in the airways of patients with chronic obstructive pulmonary disease (COPD, a relatively steroid insensitive inflammatory disease is unclear, however.Sputum, bronchoalveolar lavage (BAL macrophages and serum were obtained from non-smokers, smokers and COPD patients. To mimic oxidative stress-induced COPD, mice were exposed to ozone for six-weeks and treated with ISO-1, a MIF inhibitor, and/or dexamethasone before each exposure. BAL fluid and lung tissue were collected after the final exposure. Airway hyperresponsiveness (AHR and lung function were measured using whole body plethysmography. HIF-1α binding to the Mif promoter was determined by Chromatin Immunoprecipitation assays.MIF levels in sputum and BAL macrophages from COPD patients were higher than those from non-smokers, with healthy smokers having intermediate levels. MIF expression correlated with that of HIF-1α in all patients groups and in ozone-exposed mice. BAL cell counts, cytokine mRNA and protein expression in lungs and BAL, including MIF, were elevated in ozone-exposed mice and had increased AHR. Dexamethasone had no effect on these parameters in the mouse but ISO-1 attenuated cell recruitment, cytokine release and AHR.MIF and HIF-1α levels are elevated in COPD BAL macrophages and inhibition of MIF function blocks corticosteroid-insensitive lung inflammation and AHR. Inhibition of MIF may provide a novel anti-inflammatory approach in COPD.

    Full Text Available Destabilization of oil-water emulsion in coconut milk, in the production of virgin coconut oil (VCO, can be accelerated with the utilization of lactic acid bacteria fermentation. This research was aimed to determine physicochemical and antibacterial characteristics of VCO from coconut hybrid variety fermented with L. casei of Yakult® and two isolates of L. plantarum from mandai (traditionally fermented Artocarpus campeden and coconut water. The observed physicochemical of VCO included yield, specific gravity, moisture content, saponification value, peroxide value, and free fatty acid. The antibacterial activity was subjected to the well diffusion method against E. coli and S. aureus with chloramphenicol as the positive control. L. casei yielded the best VCO-BAL at 34.5% (v/v, while L. plantarum from mandai and coconut water yielded 29.5% (v/v and 25.3% (v/v, respectively. VCO-BAL from L. casei had the lightest specific gravity of 0.84±0.04 g.mL-1. Average of measured moisture contents (0.03-0.05%, saponification values (161.3-163.6, peroxide values (0.53-0.86, and free fatty acids (0.11-0.12% of the three VCO-BALs were not significantly (p>0.05 different with respect to control. VCO-BAL produced from L. plantarum of coconut water did not exhibit better antibacterial activity compared to control. VCO-BAL from L. casei demonstrated highest antibacterial activity against E. coli, 6.45±0.50 mm (58.1% of positive control and S. aureus, 5.23±0.40 mm (51.3% of positive control. It is deduced that antibacterial activity from VCO-BAL is contributed by hydrophobic bacteriocins.

    We report NuSTAR observations of a sample of six X-ray weak broad absorption line (BAL) quasars. These targets, at z = 0.148-1.223, are among the optically brightest and most luminous BAL quasars known at z < 1.3. However, their rest-frame ≈2 keV luminosities are 14 to >330 times weaker than expected for typical quasars. Our results from a pilot NuSTAR study of two low-redshift BAL quasars, a Chandra stacking analysis of a sample of high-redshift BAL quasars, and a NuSTAR spectral analysis of the local BAL quasar Mrk 231 have already suggested the existence of intrinsically X-ray weak BAL quasars, i.e., quasars not emitting X-rays at the level expected from their optical/UV emission. The aim of the current program is to extend the search for such extraordinary objects. Three of the six new targets are weakly detected by NuSTAR with ≲ 45 counts in the 3-24 keV band, and the other three are not detected. The hard X-ray (8-24 keV) weakness observed by NuSTAR requires Compton-thick absorption if these objects have nominal underlying X-ray emission. However, a soft stacked effective photon index (Γ{sub eff} ≈ 1.8) for this sample disfavors Compton-thick absorption in general. The uniform hard X-ray weakness observed by NuSTAR for this and the pilot samples selected with <10 keV weakness also suggests that the X-ray weakness is intrinsic in at least some of the targets. We conclude that the NuSTAR observations have likely discovered a significant population (≳ 33%) of intrinsically X-ray weak objects among the BAL quasars with significantly weak <10 keV emission. We suggest that intrinsically X-ray weak quasars might be preferentially observed as BAL quasars.

    Changes in airway inflammation can be studied with bronchoalveolar lavage, but the widespread use of this procedure is limited by its invasiveness. The aim of this study was to evaluate the usefulness of induced sputum as a non-invasive alternative to bronchoalveolar lavage for studying changes in airway inflammation in patients with asthma. Thirty patients were treated for 12 weeks with an inhaled corticosteroid (fluticasone propionate (FP), 250 microg twice daily) or a short-acting beta-agonist (salbutamol (Sb), 400 microg twice daily) in a double-blind, double-dummy, randomized parallel group study. Sputum induction with hypertonic saline solution was performed twice before treatment and after 4, 8, 10, and 11 weeks of treatment. Bronchoalveolar lavage fluid divided into two pools (first 60 mL portion as bronchoalveolar lavage/bronchial wash (BAL/BW) and subsequent 80 mL as bronchoalveoalar lavage (BAL)) was obtained before and after 12 weeks of treatment. Changes in cell differentials and plasma-protein leakage (alpha2-macroglobulin, albumin, and their ratio (relative coefficient of excretion, RCE)) were analyzed in induced sputum and were compared with changes in BAL/BW and BAL. During treatment with FP, the PC20histamine (interpolated concentration of histamine that caused a fall in FEV1 of 20% of the baseline value) increased (P < .0001), and the percentage of eosinophils (P = .004), levels of (alpha2-macroglobulin (P = .09) and RCE (P = .007) decreased in sputum. These changes were different from those in the Sb group (PC20histamine P< .0001, eosinophils P= .004, alpha2-macroglobulin P= .003, RCE P = .01), in which alpha2-macroglobulin showed a significant increase (P = .015). Changes in the percentage of eosinophils and in the levels of alpha2-macroglobulin in sputum were associated with changes in the PC20histamine (Rs = -0.59, P = .007 and Rs = -0.47, P = .03, respectively). These correlations did not reach significance in BAL/BW and BAL fluid. The

    A novel method is proposed for studying the evolution of flow phenomena with the incident energy, and for quantitatively estimating the energy of vanishing flow (also called balance energy, E{sub bal}) without reconstructing the reaction plane. We used a method based on the shapes of experimental particle-particle azimuthal correlation functions to determine E{sub bal} for three systems: Ar + Al, Zn + Ti, Zn + Ni. We compare the results with estimations using flow parameter analysis and also with theoretical expectations. (authors). 25 refs.

    The observed relation between the X-ray radiation from AGNs, originating in the corona, and the optical/UV radiation from the disk is usually described by the anticorrelation between the UV to X-ray slope alpha_ox and the UV luminosity. Many factors can affect this relation, including: enhanced X-ray emission associated with the jets of radio-loud AGNs; X-ray absorption associated with the UV Broad Absorption Line (BAL) outflows; other X-ray absorption not associated with BALs; intrinsic X-ra...

    Exposure of the respiratory tract to lipopolysaccharide (LPS) induces acute local inflammation and tissue injury associated with the various deliveries of LPS. To determine potential association of local inflammatory responses with respiratory tract dysfunction, infiltration of inflammatory cells, production of inflammatory mediators, lung hyperinflation and edema were measured in Wister rats 2, 4, and 24 h after an intratracheal administration of LPS at different doses (5, 50, 500 and 5000 microg/ml/kg). Lung hyperinflation determined by an increased excised lung gas volume was significantly increased 2 and 4 h after LPS instillation and lung edema occurred from 2 h onward. Peak BAL levels of TNFalpha appeared at 2 h, MCP-1 at 4 h, and IL-6 at 2 and 4 h, while BAL levels of IL-1beta were increased during 24 h after the intratracheal instillation of LPS. Neutrophilia in BAL fluid was noted from 2 h post-challenge. Our results demonstrate a clear dose-related change in the lung weight at 4 and 24 h, in the BAL levels of MCP-1 at 4 h, and IL-6 and IL-1beta at 2 and 4 h. It seems important to understand polymorphisms of LPS-induced lung hyperinflation and inflammation. Lung hyperinflation and inflammation may be independent during the development of acute lung injury.

    Ventilator-associated pneumonia (VAP) is defined as pneumonia occuring in any period of mechanical ventilation. There is no optimal diagnostic method in current use and in this study we aimed to compare two non-invasive diagnostic methods used in diagnosis of VAP in children. This prospective study was conducted in 8 bedded Pediatric Intensive Care Unit at Ege University Children´s Hospital. Endotracheal aspiration (ETA) and non-bronchoscopic bronchoalveolar lavage (BAL) were performed in case of developing VIP after 48 hours of ventilation. Quantitative cultures were examined in Ege University Department of Diagnostic Microbiology, Bacteriology Laboratory. Fourty-one patients were enrolled in the study. The mean age of study subjects was 47.2±53.6 months. A total of 28 in 82 specimens taken with both methods were negative/negative; 28 had positive result with ETA and a negative result with non-bronchoscopic BAL and both results were negative in 26 specimens. There were no patients whose respiratory specimen culture was negative with ETA and positive with non-bronchoscopic BAL. These results imply that there is a significant difference between two diagnostic methods (p ETA results were compared with this method. ETA's sensitivity, specificity, negative and positive predictive values were 100%, 50%, 100% and 48% respectively. The study revealed the ease of usability and the sensitivity of non-bronchoscopic BAL, in comparison with ETA.

    2013-01-01

    We present NuSTAR hard X-ray observations of two X-ray weak broad absorption line (BAL) quasars, PG 1004+130 (radio loud) and PG 1700+518 (radio quiet). Many BAL quasars appear X-ray weak, probably due to absorption by the shielding gas between the nucleus and the accretion-disk wind. The two targets are among the optically brightest BAL quasars, yet they are known to be significantly X-ray weak at rest-frame 2-10 keV (16-120 times fainter than typical quasars). We would expect to obtain ~400-600 hard X-ray (>10 keV) photons with NuSTAR, provided that these photons are not significantly absorbed (NH<1E24 cm^{-2}). However, both BAL quasars are only detected in the softer NuSTAR bands (e.g., 4-20 keV) but not in its harder bands (e.g., 20-30 keV), suggesting that either the shielding gas is highly Compton-thick or the two targets are intrinsically X-ray weak. We constrain the column densities for both to be NH~7E24 cm^{-2} if the weak hard X-ray emission is caused by obscuration from the shielding gas. We d...

    Full Text Available Abstract Introduction The removal of highly viscous mucus from the airways is an important task in the treatment of chronic lung disease like in cystic fibrosis. The inhalation of recombinant human DNase-I (rhDNase-I is used to facilitate the removal of tenacious airway secretions in different lung diseases and especially in CF. Little is known about endogenous DNase activity in the airway surface liquid. Therefore, we analysed bronchoalveolar lavage fluid (BAL and exhaled breath condensate (EBC for the presence of endogenous DNase activity. Methods The degradation of plasmid DNA by BAL from patients who had diagnostic bronchoscopy and bronchoalveolar lavage was analyzed. In a group of CF patients and healthy control volunteers the exhaled breath condensate was obtained and also analyzed for the ability to degrade plasmid DNA. In addition, the ability of magnesium to activate endogenous DNase activity in BAL and exhaled breath condensate was investigated. Results The analyzed BAL samples degraded plasmid DNA only after preincubation with magnesium. When analyzing the exhaled breath condensate the samples obtained from the healthy volunteers showed no DNase activity even after preincubation with magnesium, whereas in one of the two samples obtained from CF patients we found a DNase activity after preincubation with magnesium. Conclusion Increasing the magnesium concentration in the airway surface liquid by aerosolisation of magnesium solutions or oral magnesium supplements could improve the removal of highly viscous mucus in chronic lung disease by activating endogenous DNase activity.

    We have investigated a sample of 2099 broad absorption line (BAL) quasars with z=1.7-2.2 built from the Sloan Digital Sky Survey Data Release Seven and the Wide-field Infrared Survey. This sample is collected from two BAL quasar samples in the literature, and refined by our new algorithm. Correlations of outflow velocity and strength with hot dust indicator (beta_NIR) and other quasar physical parameters, such as Eddington ratio, luminosity and UV continuum slope, are explored in order to figure out which parameters drive outflows. Here beta_NIR is the near-infrared continuum slope, a good indicator of the amount of hot dust emission relative to accretion disk emission. We confirm previous findings that outflow properties moderately or weakly depends on Eddington ratio, UV slope and luminosity. For the first time, we report moderate and significant correlations of outflow strength and velocity with beta_NIR in BAL quasars. It is consistent with the behavior of blueshifted broad emission lines in non-BAL quasa...

    2013-01-01

    Quasar accretion disk winds observed via broad absorption lines (BALs) in the UV produce strong continuous absorption in X-rays. The X-ray absorber is believed to serve critically as a radiative shield to enable radiative driving. However, "mini-BAL" and narrow absorption line outflows have dramatically less X-ray absorption than BALs. Here we examine X-ray and rest-frame UV spectra of 8 mini-BAL quasars with outflow speeds in the range 0.1c to 0.2c to test whether extreme speeds require a strong shield. We find that the X-ray absorption is weak or moderate, with neutral-equivalent column densities N_H ~ 8 x 10^15 cm (based on measured line depths), the outflows have shapes like thin "pancakes" viewed face-on, or they occupy larger volumes like a spray of many dense clouds with a small volume filling factor. These results favor models with magnetic confinement in magnetic disk winds.

  9. Optical to extreme ultraviolet reddening curves for normal AGN dust and for dust associated with high-velocity outflows

    We use mid-IR (WIRE), optical (SDSS), and ultraviolet (GALEX) photometry of over 80,000 AGNs to derive mean attenuation curves from the optical to the rest frame extreme ultraviolet (EUV) for (i) “normal” AGN dust dominating the optical reddening of AGNs and (ii) “BAL dust” - the dust causing the additional extinction in AGNs observed to have broad absorption lines (BALs). Our method confirms that the attenuation curve of “normal” AGN dust is flat in the ultraviolet, as found by Gaskell et al. (2004). In striking contrast to this, the attenuation curve for BAL dust is well fit by a steeply-rising, SMC-like curve. We confirm the shape of the theoretical Weingartner & Draine (2001) SMC curve out to 700 Angstroms but the drop in attenuation to still shorter wavelengths (400 Angstroms) seems to be less than predicted. We find identical attenuation curves for high-ionization and low-ionization BALQSOs. We suggest that attenuation curves appearing to be steeper than the SMC are due to differences in underlying spectra and partial covering by BAL dust.

    Although the effects of arsenic on mammalian development are now well established, very few data on the protective activity of different chelators against embryotoxicity and teratogenicity of arsenic are available. Chelating agents may interact with teratogen metals to augment or ameliorate their actions. Researchers demonstrated that a single dose of 2,3-dimercaptopropanol (BAL) was capable of affording a degree of protection to arsenate exposed fetal mice. Subcutaneous treatment with 50 mg/kg of BAL 4 hr after arsenate reduced the frequency or severity of malformations compared with the effects of arsenate alone. However, BAL has several drawbacks. In recent years dimercaptosuccinic acid (DMSA) is receiving growing attention in the USA and Western Europe. Results of a number of different investigations in rodents have led to the conclusion that DMSA is much less toxic than BAL. Moreover, DMSA has been reported to be effective in inducing arsenic excretion. In the present study, the protective effects of DMSA in alleviating the embryotoxic and teratogenic effects of sodium arsenate were evaluated in mice.

    We have recently shown that a mouse lung infection model resulting in acute pneumonia could be used for evaluating the protective immunity induced by mucosal vaccines against Vibrio cholerae. In order to gain insight and better understanding of the pathogenicity of V. cholerae infection, we identified and compared proteins induced by V. cholerae in nasal washes, bronchoalveolar lavages (BAL), and sera. Intranasal administration of V. cholerae increased the concentration of total proteins in nasal washes and BAL fluids, but not in sera. LTQ-Orbitrap hybrid Fourier transform mass spectrometry showed that cytoskeletal proteins, protease inhibitors and anti-inflammatory mediators were present in nasal washes from uninfected mice. The distinctly expressed proteins in nasal washes in response to V. cholerae mainly consisted of protease inhibitors, anti-inflammatory proteins, and anti-microbial proteins. A number of protease inhibitors and anti-inflammatory proteins were selectively expressed in BAL fluids from V. cholerae-infected mice, while cytoskeletal proteins and heat shock proteins were mainly observed in BAL fluids from uninfected mice. A large number of serum complements, protease inhibitors, and acute phase proteins were expressed in V. cholerae-infected mice. Collectively, these results suggest that intranasal administration of V. cholerae leading to acute pneumonia elicited alterations of protein profiles associated with immune homeostasis and host protection in both the mucosal and systemic compartments.

    We use mid-IR to UV observations to derive a mean attenuation curve out to the rest-frame extreme ultraviolet (EUV) for "BAL dust" -- the dust causing the additional extinction of active galactic nuclei (AGNs) with broad absorption lines (BALQSOs). In contrast to the normal, relatively flat, mean AGN attenuation curve, BAL dust is well fit by a steeply rising, SMC-like curve. We confirm the shape of the theoretical Weingartner & Draine SMC curve out to 700 \\AA, but the drop in attenuation at still shorter wavelengths is less than predicted. The identical attenuation curve for low-ionization BALQSOs (LoBALs) does not support them being a "break out" phase in the life of AGNs. Although attenuation in the optical due to BAL dust is low ($E(B-V) \\sim 0.03 - 0.05$), the attenuation rises to one magnitude in the EUV because of the steep extinction curve. Here the dust optical depth is at the optimum value for radiative acceleration of dusty gas. Because the spectral energy distribution of AGNs peaks in the EUV ...

    Aerodynamic roughness length (z(0)) and displacement height (d(0)) are important surface parameters for estimating surface fluxes in numerical models. These parameters are generally determined from wind flow characteristics using logarithmic wind profiles measured at a meteorological tower or by bal
