  2. Through BAL Quasars Brightly

    2003-01-01

    We report on an observation of the broad absorption line (BAL) quasar PG 1115+080 performed with the XMM-Newton observatory. Spectral analysis reveals the second case of a relativistic X-ray-absorbing outflow in a BAL quasar. The first case was revealed in a recent observation of APM 08279+5255 with the Chandra X-Ray Observatory. As in the case of APM 08279+5255, the observed flux of PG 1115+080 is greatly magnified by gravitational lensing. The relatively high redshift (z=1.72) of the quasar places the redshifted energies of resonant absorption features in a sensitive portion of the XMM- Newton spectral response. The spectrum indicates the presence of complex low-energy absorption in the 0.2-0.6 keV observed energy band and high-energy absorption in the 2-5 keV observed energy band. The high-energy absorption is best modeled by two Gaussian absorption lines with rest-frame energies of 7.4 and 9.5 keV. Assuming that these two lines axe produced by resonant absorption due to Fe XXV, we infer that the X-ray absorbers are outflowing with velocities of approx. 0.10c and approx. 0.34c respectively. We have detected significant variability of the energies and widths of the X-ray BALs in PG 1115+080 and APM 08279+5255 over timescales of 19 and 1.8 weeks (proper time), respectively. The BAL variability observed from APM 08279+5255 supports our earlier conclusion that these absorbers are most likely launched at relatively small radii of less than 10(exp 16)(Mbh/M8)(sup 1/2) cm. A comparison of the ionization properties and column densities of the low-energy and high-energy absorbers indicates that these absorbers are likely distinct; however, higher spectral resolution is needed to confirm this result. Finally, we comment on prospects for constraining the kinematic and ionization properties of these X-ray BALs with the next generation of X-ray observatories.

    All properties of the quasars known by the author (quietness of the BAL quasars, Lyman forest, iron in the high-z quasars...) are explained supposing that the kernel of the quasar is surrounded by a halo containing an accretion disk and magnetic satellites (no dark matter or fast jet, no variation of the fine structure constant, no strange source of iron...). The key is taking into account the coherent light-matter interactions.

    We have selected a sample of broad absorption line (BAL) quasars which show significant radio variations, indicating the presence of polar BAL outflows. We obtained snapshot XMM observations of four polar BAL QSOs, to check whether strong X-ray absorption, one of the most prominent characteristics of most BAL QSOs, also exist in polar outflows. Two of the sources are detected in X-ray. Spectral fittings show that they are X-ray normal with no intrinsic X-ray absorption, suggesting the X-ray s...

  8. Toward a Complete Picture of Quasar Outflows: from BALs to mini-BALs

    Accretion disk outflows are important for galaxy evolution and an integral part of the quasar phenomenon, but they remain poorly understood. In order to construct a more complete picture of the quasar phenomenon, we need to understand the full range of different types of quasar outflows and how they correlate with one another. We examine seven SDSS quasars with CIV 1548,1551 Å outflow lines that span a range from strong BALs to weak mini-BALs. They have moderate redshifts (1.68 based spectra obtained at the MDM and Kitt Peak observatories to measure a variety of ions across the rest UV wavelength range. Our preliminary analysis shows OVI is present and stronger than CIV in all seven quasars. In one case, we detect an OVI mini-BAL with no accompanying CIV, requiring a highly-ionized outflow. In the strongest BAL quasar, we detect resolved PV doublet absorption that requires PV optical depths > 3 and in outflow gas with a line-of-sight covering fraction of only 0.27. Thus, the total column density in this outflow component might exceed N_H > 1023 cm-2 which has important consequences for the outflow kinetic energies and feedback. The multi-epoch CIV data reveal CIV outflow variability in all seven quasars; four become weaker, one becomes stronger, and two become both stronger and weaker over the different epochs. This variability happens across time scales of ~1-12 years in the quasar rest frames which is consistent with outflow locations close to the central quasar engines. We use these and other results to constrain the ionization, column density, and location of the absorbers with the broader goals of understanding accretion physics, the integrated structure of quasar outflows, and the impact a quasar has on its host galaxy.

    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 the 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 zem ˜ 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 quasars (HS 1603+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 mini-BAL and NAL quasars. (3) The variability of the mini-BAL and quasar light curves was weakly synchronized with a small time delay for HS 1603+3820. These results suggest that the VIS scenario may need additional mechanisms such as variable shielding by X-ray warm absorbers.

    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...

  16. BAL QSOs and Extreme UFOs: The Eddington Connection

    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.

  1. X-RAY INSIGHTS INTO THE PHYSICS OF MINI-BAL QUASAR OUTFLOWS

    International Nuclear Information System (INIS)

    We examine the ultraviolet and X-ray properties of 256 radio-quiet Sloan Digital Sky Survey quasars (QSOs) observed in X-rays with Chandra and/or XMM-Newton in order to study the relationship between QSOs with broad C IV absorption lines (BALs; width >2000 km s-1) and those with C IV mini-BALs (here defined to have widths of 1000-2000 km s-1). Our sample includes 42 BAL and 48 mini-BAL QSOs. The relative X-ray brightness and hard spectral slopes of the mini-BAL population are, on average, intermediate between those of BAL and non-BAL QSOs, as might be expected if narrower and broader absorption line outflows are physically related. However, a significant population of mini-BALs has outflow velocities higher than would be expected for BAL QSOs of the same relative X-ray brightness. Consistently strong X-ray absorption is apparently not required to accelerate at least some mini-BALs to high outflow velocities. Assuming the mini-BAL features are correctly attributed to intrinsic C IV absorption, we suggest that their observed properties may be explained if mini-BALs are 'seeds' that can be accelerated to form BALs when sufficient X-ray shielding is present. We also examine several QSOs with broad C IV absorption that have been recently reported to be unusually X-ray bright. Such cases are frequently mini-BAL QSOs, which, as a population, are generally brighter in X-rays than BAL QSOs. Pointed XMM-Newton observations also suggest that these sources (or unresolved neighbors) may have been previously observed in a high-flux state.

  2. Gene duplication and hypermutation of the pathogen Resistance gene SNC1 in the Arabidopsis bal variant.

    Yi, Hankuil; Richards, Eric J

    2009-12-01

    The bal defect in the Arabidopsis thaliana Columbia strain was spontaneously generated in an inbred ddm1 (decrease in DNA methylation 1) mutant background in which various genetic and epigenetic alterations accumulate. The bal variant displays short stature and curled leaves due to the constitutive activation of defense signaling. These bal phenotypes are metastable and phenotypic suppression is evident in more than one-third of ethyl methanesulfonate (EMS)-treated bal M(1) plants. The semidominant bal allele maps to the RPP5 (recognition of Peronospora parasitica 5) locus, which includes a cluster of disease Resistance (R) genes, many of which show an increase in steady-state expression levels in the bal variant. Here, we report that activation of RPP5 locus R genes and dwarfing in the bal variant are caused by a 55-kb duplication within the RPP5 locus. Although many RPP5 locus R genes are duplicated in the bal variant, the duplication of SNC1 alone is necessary and sufficient for the phenotypic changes in the bal variant. Missense mutations in the SNC1 gene were identified in all three phenotypically suppressed EMS-treated bal lines investigated, indicating that the high-frequency phenotypic instability induced by EMS treatment is caused by a genetic mechanism. We propose that the high degree of variation in SNC1-related sequences among Arabidopsis natural accessions follows the two-step mechanism observed in the bal variant: gene duplication followed by hypermutation.

    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...

    It is thought that a class of broad absorption line (BAL) QSOs, characterized 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 Submillimetre Common-User Bolometer Array 2 (SCUBA-2) 850 μm observations of a sample of 17 FeLoBAL QSOs with 0.89 ≤ z ≤ 2.78 and -23.31 ≤ MB ≤ -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 sub-mm, none of them are individually detected at 850 μm, nor as a population through stacking (Fs = 1.14 ± 0.58 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 Spectral Energy Distribution fitting analysis shows that the far-infrared emission is dominated by active galactic nuclei activity, and a starburst component is required only in 6/17 sources of our sample; moreover the integrated total luminosity of 16/17 sources is L ≥ 1012 L⊙, high enough to classify FeLoBALs as infrared luminous. In conclusion, we do not find any evidence in support of FeLoBAL QSOs being a transition population between an ultraluminous infrared galaxy (ULIRG) and an unobscured QSO; in particular, FeLoBALs are not characterized by a cold starburst which would support this hypothesis.

    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 radi...

  8. BAL QSOs and Extreme UFOs: the Eddington connection

    2013-01-01

    We suggest a common physical origin connecting the fast, highly ionized winds (UFOs) seen in nearby AGN, and the slower and less ionized winds of 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 towards 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 $\\sim 10-50$...

    The first multifrequency radio observations of the very compact BAL quasar, 1045+352, were made using MERLIN and the VLBA in a snapshot mode. However, its unusual radio structure was still very difficult to interpret, indicating a scenario of intermittent activity or a jet precession. Here, we present some of a new full-track radio observations of 1045+352 made with the EVN+MERLIN at 5 GHz. The new more sensitive high-resolution observations made possible to trace the connection between the arcsecond structure and the radio core, and showed the presence of strong interactions between the jet and the medium of the host galaxy.

    2005-01-01

    We present observations of the most radio-luminous BAL quasar known, 1624+3758, at redshift z = 3.377. The quasar has several unusual properties: (1) The FeII UV191 1787-A emission line is very prominent. (2) The BAL trough (BALnicity index 2990 km/s) is detached by 21000 km/s and extends to velocity v = -29000 km/s. There are additional intrinsic absorbers at -1900 and -2800 km/s. (3) The radio rotation measure of the quasar, 18350 rad/m^2, is the second-highest known. The radio luminosity is P(1.4GHz) = 4.3 x 10^27 W/Hz (H0 = 50 km/s/Mpc, q0 = 0.5), radio loudness R* = 260. The radio source is compact (<~ 2.8 kpc) and the radio spectrum is GHz-peaked, consistent with it being relatively young. The width of the CIV emission line, in conjunction with the total optical luminosity, implies black-hole mass ~ 10^9 M(sun), L/L(Eddington) ~ 2. The high Eddington ratio, and the radio-loudness, place this quasar in one corner of Boroson's (2002) 2-component scheme for the classification of AGN, implying a very hig...

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

    CERN Document Server

    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'...

  15. The Nature of LoBAL QSOs: I. SEDs and mid-infrared spectral properties

    Lazarova, Mariana S; Lacy, Mark; Sajina, Anna

    2012-01-01

    We have obtained Spitzer IRS spectra and MIPS 24, 70, and 160 micron photometry for a volume-limited sample of 22 SDSS-selected Low-ionization Broad Absorption Line QSOs (LoBALs) at 0.5 10^12*L_sun). We estimate star formation rates (SFRs) corrected for the AGN contribution to the FIR flux and find that LoBALs have comparable levels of star formation activity to non-LoBALs when considering the entire samples. However, the SFRs of the IR-luminous LoBALs are 80% higher than those of their counterparts in the control sample. The median contribution of star formation to the total far-infrared flux in LoBALs and in non-LoBALs is estimated to be 40-50%, in agreement with previous results for PG QSOs. Overall, our results show that there is no strong evidence from the mid- and far-IR properties that LoBALs are drawn from a different parent population than non-LoBALs.

    The results of a sub-millimeter survey of SDSS broad CIV absorption line quasars is discussed. It is found that the sub-millimeter flux distribution of BAL quasars is similar to that of non-BAL quasars. This is consistent with the idea that all quasars contain broad absorption line regions, but only a fraction of them are visible along our line-of-sight. The observations are inconsistent with BAL quasars being observed at a special evolutionary epoch co-inciding with a high star-formation rat...

    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...

    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...

    Coal workers' pneumoconiosis (CWP) is an occupational pulmonary disease that occurs by chronic inhalation of coal dust. CWP is divided into two stages depending on the extent of the disease, as simple pneumoconiosis (SP) and progressive massive fibrosis (PMF). In the present study, serum and bronchoalveolar lavage (BAL) cytokine (interleukin-1 beta (IL-1 beta), IL-6, tumor necrosis factor-alpha (TNF-alpha), transforming growth factor-beta (TGF-beta)) and antioxidant enzymes levels, their relation with the disease severity, and whether they can be considered as biological markers were investigated. Serum and BAL levels of IL-1 beta, IL-6, and TNF-alpha were higher in SP and PMF patient groups compared with that in active and retired miner groups. Serum and BAL IL-1 beta, IL-6, and TNF-alpha levels were also found to be higher in patients with PMF compared with the SP group. BAL superoxide dismutase (SOD), glutathione peroxidase, and catalase levels and serum SOD level were increased in both patient groups compared with the control group. In addition, mean serum and BAL TGF-beta levels were found to be increased in patients with SP compared with PMF group. Based on these results, BAL and serum cytokine and antioxidant enzymes levels were evaluated and discussed as potential biomarkers for different stages of CWP.

  7. THE X-RAY PROPERTIES OF THE OPTICALLY BRIGHTEST MINI-BAL QUASARS FROM THE SLOAN DIGITAL SKY SURVEY

    International Nuclear Information System (INIS)

    We have compiled a sample of 14 of the optically brightest radio-quiet quasars (mi ≤ 17.5 and z ≥ 1.9) in the Sloan Digital Sky Survey Data Release 5 quasar catalog that have C IV mini-broad absorption lines (mini-BALs) present in their spectra. X-ray data for 12 of the objects were obtained via a Chandra snapshot survey using ACIS-S, while data for the other two quasars were obtained from archival XMM-Newton observations. Joint X-ray spectral analysis shows that the mini-BAL quasars have a similar average power-law photon index (Γ ∼ 1.9) and level of intrinsic absorption (NH ∼21 cm-2) as non-BMB (neither BAL nor mini-BAL) quasars. Mini-BAL quasars are more similar to non-BMB quasars than to BAL quasars in their distribution of relative X-ray brightness (assessed with Δαox). Relative colors indicate mild dust reddening in the optical spectra of mini-BAL quasars. Significant correlations between Δαox and UV absorption properties are confirmed for a sample of 56 sources combining mini-BAL and BAL quasars with high signal-to-noise ratio rest-frame UV spectra, which generally supports models in which X-ray absorption is important in enabling driving of the UV absorption-line wind. We also propose alternative parameterizations of the UV absorption properties of mini-BAL and BAL quasars, which may better describe the broad absorption troughs in some respects.

    Community-acquired and nosocomial infections caused by multidrug-resistant Gram-positive pathogens continue to increase in prevalence and have become a serious problem in many parts of the world. BAL9141 is a member of the class of parenteral pyrrolidinone-3-ylidenemethyl cephalosporins, and has a broad spectrum of activity. In the current study, BAL9141 was tested against a large number (n = 2263) of recent isolates from various international surveillance programmes including 1097 Gram-positive strains. Susceptibility to (S) and activity of (mg/L) to BAL9141, based on proposed breakpoints (MIC50/MIC90/% S) were as follows: methicillin-susceptible Staphylococcus aureus (0.5/0.5/100%), methicillin-resistant S. aureus (MRSA) (1/2/100%), methicillin-susceptible coagulase-negative staphylococci (CoNS) (0.12/0.25/100%), methicillin-resistant CoNS (MR-CoNS) (1/2/100%), Streptococcus pneumoniae (32/>32/22%), Haemophilus influenzae (0.06/0.06/100%), Moraxella catarrhalis (0.06/0.5/100%), Neisseria gonorrhoeae (0.03/0.06/100%) and Neisseria meningitidis (98%) were also higher than to CRO (86%) and LVX (96%). BAL9141 demonstrated excellent activity against most species of wild-type enteric bacilli, with > or = 95% of isolates being susceptible; however, only modest activity was observed for BAL9141 against non-fermentative Gram-negative species and ESBL-producing Escherichia coli or Klebsiella pneumoniae. BAL9141 demonstrated excellent activity against many tested pathogens displaying various resistance phenotypes, and should be particularly valuable in the treatment of MRSA as well as for drug-resistant streptococci, while maintaining a spectrum resembling a 'third-generation' cephalosporin against other clinically important species.

    Clara cell secretory protein (CC16) is associated with Th2 modulation. Surfactant protein D (SPD) plays an important role in surfactant homeostasis and eosinophil chemotaxis. We measured CC16 and SPD in sputum supernatants of 84 asthmatic patients and 12 healthy controls. In 22 asthmatics, we additionally measured CC16 and SPD levels in BAL and assessed smooth muscle area (SMA), reticular basement membrane (RBM) thickness, and epithelial detachment (ED) in bronchial biopsies. Induced sputum CC16 and SPD were significantly higher in patients with severe asthma (SRA) compared to mild-moderate and healthy controls. BAL CC16 and SPD levels were also higher in SRA compared to mild-moderate asthma. CC16 BAL levels correlated with ED, while SPD BAL levels correlated with SMA and RBM. Severity represented a significant covariate for these associations. CC16 and SPD levels are upregulated in SRA and correlate with remodeling indices, suggesting a possible role of these biomarkers in the remodeling process. PMID:25728058

    Full Text Available Abstract Background and aims Anxiety and depression are common in patients with chronic obstructive pulmonary disease (COPD. The degree of lung function may not explain anxiety and depression. The aim of our study was to assess the psychological aspects of COPD, to test the BODE index (a composite score of body mass, obstruction, dyspnea and exercise capacity, and to evaluate the association between atypical cytologic findings of sputum, bronchoalveolar lavage (BAL and the pyschological components of the disease. Methods COPD was classsified according to the GOLD stages based on forced expiratory volume in 1 second (FEV1 in 60 stable patients. The BODE index was calculated for grading COPD. The Hospital anxiety and depression (HAD scale was used to appraise the anxiety and depression symptoms. Cytologic examination of sputum and BAL samples were performed in each patient. The cytologic findings were classified as normal, mild, moderate or severe atypia. Results The overall prevalance of anxiety and depression symptoms was 41.7% and 46.7% respectively. The prevalance of these symptoms increased with increasing BODE stages and correlated well with the severity of atypical BAL cytology results (p Conclusions We conclude that the BODE index is superior to GOLD stratification for explaining anxiety and depression symptoms in COPD. BAL cytologic findings, which reflect the distal parenchymal lung structure, correlated significantly with the presence of the anxiety and depression symptoms.

    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.

    The objective of this study was to review the literature on bronchoalveolar lavage fluid cell profiles in healthy children and adolescents, as well as on the use of BAL as a diagnostic and follow-up tool for lung disease patients in this age bracket. To that end, we used the Medline database, compiling studies published between 1989 and 2009 employing the following MeSH descriptors (with Boolean operators) as search terms: bronchoalveolar lavage AND cytology OR cell AND child. In healthy children, the cell profile includes alveolar macrophages (> 80%), lymphocytes (approximately 10%), neutrophils (approximately 2%) and eosinophils (< 1%). The profile varies depending on the disease under study. The number of neutrophils is greater in wheezing children, especially in non-atopic children, as well as in those with pulmonary infectious and inflammatory profiles, including cystic fibrosis and interstitial lung disease. Eosinophil counts are elevated in children/adolescents with asthma and can reach high levels in those with allergic bronchopulmonary aspergillosis or eosinophilic syndromes. In a heterogeneous group of diseases, the number of lymphocytes can increase. Evaluation of the BAL fluid cell profile, when used in conjunction with clinical and imaging findings, has proven to be an essential tool in the investigation of various lung diseases. Less invasive than transbronchial and open lung biopsies, BAL has great clinical value. Further studies adopting standard international protocols should be carried out. Such studies should involve various age groups and settings in order to obtain reference values for BAL fluid cell profiles, which are necessary for a more accurate interpretation of findings in children and adolescents with lung diseases.

    Full Text Available Background: The frequency of invasive opportunistic mycoses has increased significantly over the past decades especially in immunocompromised patients. Invasive aspergillosis (IA has become a major cause of morbidity and mortality among these patients. As bronchoalveolar lavage (BAL fluid samples are generally useful specimens in the diagnosis of invasive pulmonary aspergillosis (IPA, this study was designed to evaluate the incidence of fungal elements in at-risk patients by direct microscopy and culture of BAL samples.Methods: In a 16-month period, 400 BAL samples were obtained from several groups of different patients with pulmonary and respiratory disorders and examined by using both direct microscopy and culture.Results: Of the 400 samples, 16 (4% were positive direct examination with branching septate hyphae and 46 (11.5% were positive culture: 25 (54% Aspergillus flavus, 6 (13% A. fumigatus, 5 (10.9% A. niger, 1 (2.2% A. terreus, 3 (6.5% Penicillium spp. and 6 (13% mixed A. flavus/A. niger. A. flavus was the most common cause of Aspergillus infection or colonization. Bone marrow transplant (BMT recipients were the most susceptible group to fungal infection and/or colonization.Conclusion: Among Aspergillus species, A. flavus was the most common isolate in both infections and colonization in Iran. More studies are needed to clarify the epidemiological aspect of aspergillosis in Iran.

    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.

  5. ORIGIN OF THE COMPLEX RADIO STRUCTURE IN BAL QSO 1045+352

    International Nuclear Information System (INIS)

    We present new, more sensitive, high-resolution radio observations of a compact broad absorption line (BAL) quasar, 1045+352, made with the EVN+MERLIN at 5 GHz. These observations allowed us to trace the connection between the arcsecond structure and the radio core of the quasar. The radio morphology of 1045+352 is dominated by a knotty jet showing several bends. We discuss possible scenarios that could explain such a complex morphology: galaxy merger, accretion disk instability, precession of the jet, and jet-cloud interactions. It is possible that we are witnessing an ongoing jet precession in this source due to internal instabilities within the jet flow; however, a dense environment detected in the submillimeter band and an outflowing material suggested by the X-ray absorption could strongly interact with the jet. It is difficult to establish the orientation between the jet axis and the observer in 1045+352 because of the complex structure. Nevertheless, taking into account the most recent inner radio structure, we conclude that the radio jet is oriented close to the line of sight, which can mean that the opening angle of the accretion disk wind can be large in this source. We also suggest that there is no direct correlation between the jet-observer orientation and the possibility of observing BALs.

    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.

    Full Text Available Objective: This study aimed to investigate the smoking prevalence and associated factors among the students of Balıkesir University and determine the level of nicotine dependence in smokers. Methods: Six faculties and two graduate schools located at the Balıkesir University campus were enrolled. The cluster method was used as the sampling method. To observe the rates of smoking initiation while studying at the university, first-year and final year students were compared. Results: A total of 1096 students were enrolled, with a mean age of 20.4±2.2 years. The regular smoking prevalence rate was 25.5%, occasional smoking rate was 9.5%, alcohol consumption rate was 28.0%, and drug abuse rate was 5.0%. The mean age for attempting to smoke was 16.6±2.2 years. The leading causes of smoking were curiosity, spiritual space, affection, and to comply with friends. According to the Fagerström questionnaire, the level of nicotine dependence was low in 53.0% of the participants, moderate in 8.7%, and high in 28.4%. The average smoking prevalence rate was 23.6% in first-grade students, whereas it was 44.8% in last-grade students. The factors that influence smoking were as follows: being in the last grade, mother, siblings, and friends who smoke, higher allowance, use of alcohol and drugs. Smoking was found to be more prevalent among males. Conclusion: Last-grade students had a higher smoking prevalence rate than the first-grade students. Family, social environment, and smoking behavior of friends have an influence on smoking. All risk factors, including past history and university period, should be considered together in tobacco control.

  16. Morphogenesis of the demyelinating lesions in Baló's concentric sclerosis.

    Science.gov (United States)

    Barz, Helmut; Barz, Ulrich; Schreiber, Almut

    2016-06-01

    In tissues with elastic properties, an edema causes a raised tissue pressure and therefore a diminished blood flow. The authors assume that an increased tissue pressure due to local and/or relapsing edema may be the cause for incomplete necrosis (e.g. demyelinated lesions) or seldom complete necrosis in the brain. Newly forming demyelinating lesions seldom show small tissue bands with normal appearing myelin sheaths in the immediate vicinity of precursor lesions (Baló type of MS). The small myelinated bands are the result of a "protected zone" on the edge of previous demyelinated lesions. The authors explain this protected zone with two arguments. Firstly, the resorptive granulation tissue of more or less older lesions is relatively rich in capillaries. These capillaries may act as an energy reservoir that can nourish not only the plaque, but also a narrow adjacent myelinated tissue band by diffusion, even if the capillary blood flow in this tissue band is limited due to the greater tissue pressure of a new developing lesion in the neighborhood. Secondly, another protective mechanism may act simultaneously: older or more sclerosed lesions and small adherent bands of myelinated tissue with them may swell less in cases of an edema than in normal tissue. The hardening of the older lesions is caused by proliferated fiber-forming astrocytes in the sense of scarring. In an area with an increased tissue pressure, the capillaries are less compressed in a sclerosed lesion than in regions of normal grey and white matter. In addition, the adherent myelinated tissue band closest to the edge of a hardened plaque is better protected against swelling and compression than the further away tissue. Theoretically, this protection zone is comparable with protected blood vessels in the Haversian canals or the medullary spaces of bones. Both theses of protecting mechanisms at the edges of demyelinated lesions support the assumption of a hypoxic causation principle of demyelinating

    The geometrical and electronic structures of the electron-deficient dialuminum aurides Al2Aun(0/-) and hybrid boron-aluminum aurides BAlAun(0/-) (n = 1-3) are systematically investigated based on the density and wave function theories. Ab initio theoretical evidence strongly suggests that bridging gold atoms exist in the ground states of C2v Al2Au(-) ((3)B1), C2v Al2Au ((2)B1), C2v Al2Au2(-) ((2)A1), C2v Al2Au2 ((1)A1), Cs Al2Au3(-) ((1)A'), and D3h Al2Au3 ((2)A1), which prove to possess an Al-Au-Al τ bond. For BAlAun(0/-) (n = 1-3) mixed clusters, bridging B-Au-Al units only exist in Cs BAlAu3(-) ((1)A') and Cs BAlAu3 ((2)A'), whereas Cs BAlAu(-) ((3)A''), Cs BAlAu ((2)A''), Cs BAlAu2(-) ((2)A'), and Cs BAlAu2 ((1)A') do not possess a bridging gold, as demonstrated by the fact that B-Al and B-Au exhibit significantly stronger electronic interaction than Al-Au in the same clusters. Orbital analyses indicate that Au 6s contributes approximately 98%-99% to the Au-based orbital in these Al-Au-Al/B-Au-Al interactions, whereas Au 5d contributes 1%-2%. The adiabatic and vertical detachment energies of Al2Aun(-) (n = 1-3) are calculated to facilitate future experimental characterizations. The results obtained in this work establish an interesting τ bonding model (Al-Au-Al/B-Au-Al) for electron-deficient systems in which Au 6s plays a major factor. PMID:23718624

This paper is a study of the effects of wind speed, insolation levels, and the meteorological parameters of temperature and humidity on the energy potential in Balıkesir, in the Marmara region of Turkey. The relationship between the parameters was studied using a multiple linear regression method. Using a designed-for-purpose computer program, two different regression equations were derived, with wind speed being the dependent variable in the first and insolation levels in the second. The regression equations yielded accurate results. The computer program allowed for the rapid calculation of different acceptance rates. The results of the statistical analysis proved the reliability of the equations. An estimate of identified meteorological parameters and unknown parameters could be produced with a specified precision by using the regression analysis method. The regression equations also worked for the evaluation of energy potential.

    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 GALFIT models of a complete optically-selected volume-limited sample of Low-Ionization Broad Absorption Line QSOs (LoBALs) in the redshift range 0.5-0.6 observed with HST WFC3 UVIS F475W. We investigate the morphologies in the rest frame u which map the younger stellar populations. In addition, we present statistics on the number of neighborhood galaxies within 150 kpc and possible trends between clustering and host galaxy properties. This sample of LoBALs is selected from QSOs characterized by their extreme blue-shifted absorption in the Mg II line—which is a signature of high velocity winds towards the observer. Only ~1-3% of optically selected QSOs are LoBALs. Their low fraction could be explained by their orientation or by a short period of outflow manifest in all QSOs during their lifetime. We aim to better understand the possibility of the evolutionary model by studying their morphologies in detail. Previous work on this sample, from images with F125W filter (rest frame i), shows that at least 60% of these objects exhibit signs of recent merger activity. We complement those results with our results from the UVIS observations and neighborhood clustering statistics.

    Full Text Available A combinação de propriedades físicas e mecânicas qualificam as cerâmicas para aplicações em sistemas de proteção balística. Materiais cerâmicos normalmente formam a primeira camada de um sistema de blindagem mista, recebendo o impacto inicial do projétil, e dissipando grande parte da energia cinética ao fragmentar o projétil. Os principais materiais cerâmicos para blindagem balística são a alumina, o carbeto de silício e o carbeto de boro. Novas técnicas de processamento de materiais cerâmicos além do modelamento do mecanismo de fratura sob alto impacto energético são áreas que têm sido amplamente investigadas. Desenvolvimentos em particular na área de compósitos de matriz cerâmica, reforçados com fibras ou com base na transformação por tenacificação abrem novas perspectivas de uso e de melhor desempenho de sistemas de proteção balística a base de materiais cerâmicos.

    This annex study to a phase 1 study aimed to correlate urinary concentrations and bactericidal titers (UBTs) of BAL30072, a novel siderophore monosulfactam, in healthy subjects in order to evaluate which dosage of BAL30072 should be investigated in a clinical study on complicated urinary tract infection (UTI). Three cohorts of a total of 19 healthy male subjects were included in the add-on study and received the following BAL30072 dosages. The 1st cohort received 1 g once a day (q.d.) intravenously (i.v.) (1 h) on day 1 and 1 g thrice daily (t.i.d.) on day 2, the 2nd cohort received 2 g q.d. i.v. (1 h) on day 1 and 2 g t.i.d. on day 2, and the 3rd cohort received 1 g q.d. i.v. (4-h infusion) on day 8. Urine was collected up to 24 h after drug administration. UBTs were determined for seven Escherichia coli isolates (three wild type [WT], CTX-M-15, TEM-3, TEM-5, NDM-1), two Klebsiella pneumoniae isolates (WT, KPC), one Proteus mirabilis isolate (WT), and two Pseudomonas aeruginosa isolates (WT, VIM-1 plus AmpC). Urine drug concentrations were measured by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The median urinary excretions of BAL30072 ranged between 38% and 46% (3 cohorts). The median UBTs after i.v. administration of 1 or 2 g q.d. and after 1 or 2 g t.i.d. showed positive UBTs for 24 h after the lowest dosage (1 g q.d.) for 5 of 7 of the Enterobacteriaceae strains and after the higher dosage of 2 g administered i.v. t.i.d. for all strains tested. After i.v. infusion of 1 g over 4 h, positive UBTs were demonstrated for three E. coli strains for up to 12 h, for the K. pneumoniae (KPC) strain for up to 8 h, and for the P. aeruginosa (VIM-1 plus AmpC) strain for up to only 4 h. The minimal bactericidal concentrations (MBCs) of the E. coli (NDM-1) strain and the K. pneumoniae (WT) strain correlated well between broth and urine but did not correlate well for the two P. aeruginosa strains. BAL30072 exhibits positive UBTs for 24 h even after a dosage of 1

    Acute rejection of the transplanted lung is a clinical problem, since it decreases graft survival and predisposes the patient to chronic rejection and obliterative bronchiolitis (OB). In an earlier study, we had indications that eosinophil cationic protein (ECP) from activated eosinophils and hyaluronan (HYA) from fibroblasts were associated with acute pulmonary rejection. This prospective longitudinal study was designed to investigate whether molecules from activated inflammatory cells in bronchoalveolar lavage (BAL) fluid could serve as clinically useful diagnostic markers for acute rejection. BAL fluid from 138 bronchoscopies performed in 10 single lung, four bilateral lung and five heart-lung transplant recipients were analysed. Nine patients were studied for a period of more than 1 yr (mean 13.4 months) after surgery. Differential cell counts were made from the BAL fluid. ECP, myeloperoxidase (MPO), HYA and interleukin-8 (IL-8) were used as indirect markers for activation and attraction of eosinophils, neutrophils and fibroblasts, respectively. Fifty four episodes of acute rejection were diagnosed. Two patients developed OB. Nine episodes of bacterial infection, 13 episodes of cytomegalovirus (CMV) pneumonitis, three of Pneumocystis carinii infection and one of respiratory syncytial virus (RSV) infection were diagnosed. The mean levels of ECP, MPO, HYA and IL-8 were all higher during rejection episodes, but differences were not statistically significant compared to no rejection, when the confounding factors of time, concomitant infection, and repeated measures in the same individual had been accounted for. We could not confirm that measurements of eosinophil cationic protein, myeloperoxidase, hyaluronan and interleukin-8 in bronchoalveolar lavage fluid can be used as diagnostic markers for acute rejection in the postoperative follow-up of lung transplant recipients.

    The major cause of mortality in the long-term in lung transplant recipients is chronic rejection. This is a fibroproliferative process in the small airways leading to obliterative bronchiolitis and progressive loss of lung function, both constituting the clinical entity bronchiolitis obliterans syndrome (BOS). Granulocyte activation has been implicated as one factor behind BOS. Granulocyte markers in bronchoalveolar lavage (BAL) fluid were prospectively and longitudinally studied in order to identify possible association with BOS. BAL fluid from 266 bronchoscopy procedures performed in twelve single lung, eight bilateral lung and five heart/lung transplant recipients were analysed. The majority (19 of 25) were studied for a period of 2 yrs after surgery. Myeloperoxidase (MPO), eosinophil cationic protein (ECP) and interleukin-8 (IL-8) levels were used as indirect markers of activation and attraction of granulocytes. Five patients developed BOS. Ninety-eight episodes of acute rejection, nine of bacterial infection, 19 of cytomegalovirus pneumonitis, nine of Pneumocystis carinii infection, two of aspergillus infection and two of respiratory syncytial virus infection were diagnosed. BOS patients had significantly higher mean levels of MPO, ECP and IL-8 compared to patients without BOS, irrespective of acute rejection status. Over time, the five patients with BOS had significantly elevated BAL fluid levels of MPO and ECP as well as neutrophil percentages, and in four patients this increase preceded the clinical diagnosis of BOS by several months. Elevated bronchoalveolar lavage fluid neutrophil percentage as well as levels of the granulocyte activation markers myeloperoxidase and eosinophil cationic protein appear to be early signs of development of BOS in lung transplant recipients.

    [Objective] This study was to investigate the relationship between biological characteristics of Beauveria bassiana (Bals.) Vuill and pathogenicity to Bombyx rnori L, with the aim to provide scientific basis for the control of white muscardine in Bombyx mori L. [Method] The strains isolated and purified from the 6 Beauveria bassiana biocontrol agents from all over the country and the 3 white muscardine silkworms collected from Guangxi provincial silkworm rearing areas were identified by the morphological observation and molecular biology technology. The pathogenicity of B. bassaina to silkworms was determined, and the biological characteristics such as growth diameter, sporulation and the extracellular protease activity of the different B. bassiana strains were compared. [Result] The isolated 9 strains were all B. bassaina (Bals.) Vuillemin, and all strains had high pathogenicity to silkworm, but with different pathogenicities. The growth diameter, sporulation and extracellular protease activity of different B. bassiana strains were also different, and showed correlation with the patheogenicity to silkworms. [Conclusion] B. bassiana spores production amount and exocellular protease activity had significant positive correlation with their pathogenicity to silkworm.

    Inorganic dust inhalation diseases represent one of the most important chapters in respiratory medicine because of their diagnostic, therapeutic, legal, ecological and social implications. While, in fact, toxic substances inhalation may be easily related to particular occupations, it is more difficult to recognize the potential damage represented by occasional and fortuitous exposition due to pollution of one's living environment. The aim of this study was to suggest a useful investigative method for detecting the presence of mineral substances (dusts and fibers) in the lung in pulmonary fibrosis of uncertain origin. We used scanning electron microscopy (SEM) and semi-quantitative energy-dispersive x-ray microanalysis (EDXA) on broncholaveolar lavage (BAL) and sputum samples of 10 patients, all males, aged 41-66 years, smokers, affected by interstitial lung disease. Two subjects had a negative professional anamnesis while the other 8 declared a potential exposition to inorganic toxic dusts: 2 subjects were involved in the production of asbestos-containing building materials, 2 were miners, 1 a ceramic worker, and 3 insulating materials handlers. Data are reported on the detection of asbestos bodies, vitreous fibers and silica content of alveolar macrophages in BAL fluid. PMID:12619383

    We report the detection of a Broad Absorption Line (BAL) outflow in the spectrum of Tol 1037-2703 with three main BALs at 36000, 25300 and 22300~\\kms outflow velocities. Although the overall flow is dominated by high ionization lines like and C IV, the gas of highest velocity shows absorption from Mg I, Mg II and Fe II. Covering factor arguments suggest that the absorbing complexes are physically associated with the QSO and have transverse dimensions smaller than that of the UV continuum emitting region (r<0.1 pc). We show that the C IV absorption at \\zabs=2.082 has a covering factor $\\sim$ 0.86 and the absorption profile has varied over the last four years. The detection of absorption from excited fine structure levels of C II and Si II in narrow components embedded in the C IV trough reveals large density inhomogeneities. IR pumping is the most likely excitation process. The \\zabs=2.139 system is a damped system with log N(H I) ~ 19.7. The weakness of the metal lines together with the high quality of the...

    Full Text Available Abstract Objective To analyze cytokine levels in BAL fluid of patients with bronchiectasis due to mustard gas inhalation. Patients 29 victims with mustard gas-induced bronchiectasis and 25 normal veterans as control group. Intervention PFTs,, high-resolution CT scans of the chest, analyses of BAL fluids for five cytokines (IL-8, IL-1β, IL-6, TNF-α, IL-12 and analyses of BAL fluids for cellular and flow-cytometric analysis of the phenotype of bronchoalveolar cells were performed in all cases. Results CD4 lymphocytes expressed as percentage or absolute number were significantly higher in patients with bronchiectasis than in controls (32.17 ± 16.00 vs 23.40 ± 6.97%, respectively; p = 0.01; and 3.31 ± 2.03 vs 1.88 ± 0.83 × 103 cells/ml, respectively; p = 0.001. The CD4/CD8 ratio was significantly higher in patients with bronchiectasis than in controls (3.08 ± 2.05 vs 1.68 ± 0.78; p = 0.002. There were significant differences in cytokine (IL-8, IL-1β, IL-6, TNF-α, IL-12 levels of BAL fluid between patients with bronchiectasis and healthy controls. A significant correlation was observed between the HRCT scores and both the percentage and the absolute number of CD4 lymphocytes in BAL fluid in patients with bronchiectasis (r = -0.49, p = 0.009; r = -0.50, p = 0.008; respectively. HRCT scores showed a significant correlation with CD4/CD8 ratios (r = 0.54, p = 0.004 too. Of measured BAL cytokines, only IL-8 (r = -0.52, p = 0.005 and TNF-aα (r = 0.44, p = 0.01 showed significant correlations with the HRCT scores. Conclusion The increased levels of cytokines CD4 lymphocytes in the BAL fluid suggest the possible causative mechanism in the lung in sulfur mustard gas-induced bronchiectasis by the recruitment of neutrophils into the lung.

  8. BAL PHOSPHORUS ABUNDANCE AND EVIDENCE FOR IMMENSE IONIC COLUMN DENSITIES IN QUASAR OUTFLOWS: VLT/X-SHOOTER OBSERVATIONS OF QUASAR SDSS J1512+1119

    International Nuclear Information System (INIS)

    We present spectroscopic analysis of the broad absorption line (BAL) outflow in quasar SDSS J1512+1119. In particular, we focus our attention on a kinematic component in which we identify P V and S IV/S IV* absorption troughs. The shape of the unblended phosphorus doublet troughs and the three S IV/S IV* troughs allow us to obtain reliable column density measurements for these two ions. Photoionization modeling using these column densities and those of He I* constrain the abundance of phosphorus to the range of 0.5-4 times the solar value. The total column density, ionization parameter, and metallicity inferred from the P V and S IV column densities lead to large optical depth values for the common transition observed in BAL outflows. We show that the true C IV optical depth is ∼1000 times greater in the core of the absorption profile than the value deduced from its apparent optical depth.

  11. On the Covering Fraction Variability in an EUV Mini-BAL Outflow from PG 1206+459

    2015-01-01

    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.

    Because of their intense vegetation and the fact that they include areas of coastline, deltas situated in the vicinity of big cities are areas of greet attraction for people who wish to get away from in a crowded city. However, deltas, with their fertile soil and unique flora and fauna, need to be protected. In order for the use of such areas to be planned in a sustainable way by local authorities, there is a need for detailed data about these regions. In this study, the changes in land use of the Balçova Delta, which is to the immediate west of Turkey's third largest city Izmir, from 1957 up to the present day, were investigated. In the study, using aerial photographs taken in 1957, 1976 and 1995 and an IKONOS satellite image from the year 2005, the natural and cultural characteristics of the region and changes in the coastline were determined spatially. Through this study, which aimed to reveal the characteristics of the areas of land already lost as well as the types of land use in the Balçova delta and to determine geographically the remaining areas in need of protection, local authorities were provided with the required data support. Balçova consists of flat and fertile wetland with mainly citrus-fruit orchards and flower-producing green houses. The marsh and lagoon system situated in the coastal areas of the delta provides a habitat for wild life, in particular birds. In the Balçova Delta, which provides feeding and resting for migratory birds, freshwater sources are of vital importance for fauna and flora. The settlement area, which in 1957 was 182 ha, increased 11-fold up to the year 2005 when it reached 2,141 ha. On the other hand, great losses were determined in farming land, olive groves, forest and in the marsh and lagoon system. This unsystematic and rapid urbanization occurring in the study region is not only causing the loss of important agricultural land and wetland, but also lasting water and soil pollution.

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.

    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.

    Phlomis linearis Boiss. & Bal. of the Lamiaceae family growing in central, east and southeast Anatolia is an endemic species for Turkey. The essential oil obtained from the aerial parts by hydro distillation was subsequently analyzed by GC/MS. The main components of the oil were found as beta-caryophyllene (24.2%), germacrene D (22.3%) and caryophyllene oxide (9.2%), among 49 identified compounds, representing 94.5% of the total essential oil. The overall biological activity of the essential oil (100 microg/pellet) was tested on the chorioallantoic membrane (CAM) of the fertilized hen's egg in order to examine the anti-angiogenic and anti-inflammatory activity. None of the tests showed pronounced activity, toxicity or irritation at the tested concentration. PMID:14713159

    2012-01-01

    We present spectroscopic analysis of the broad absorption line outflow in quasar SDSS J1512+1119. In particular, we focus our attention on a kinematic component in which we identify PV and SIV/SIV* absorption troughs. The shape of the unblended phosphorus doublet troughs and the three SIV/SIV* troughs allow us to obtain reliable column density measurements for these two ions. Photoionization modelling using these column densities and those of HeI* constrain the abundance of phosphorus to the range of 0.5-4 times the solar value. The total column density, ionization parameter and metalicity inferred from the PV and SIV column densities leads to large optical depth values for the common transition observed in BAL outflows. We show that the true CIV optical depth, is about 1000 times greater in the core of the absorption profile than the value deduced from its apparent optical depth.

    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{sup –3}) 5.5-8, the log hydrogen column density (cm{sup –2}) 21.7-21.9, the absorption radius 7.2-127 pc, and the kinetic luminosity is 0.16%-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 an outflow velocity of ∼3400 km s{sup –1} have appeared between 2005 and 2011, suggesting that dense cores may have condensed inside the main outflow. Consideration of the literature might suggest that the FBQS J1151+3822 outflow is a member of a rare and distinct subclass of FeLoBALs with high densities and correspondingly small absorption radii. We find, however, that such outflows are not necessarily a distinct subclass, and that their apparent rarity could be a symptom of selection bias in studies using density-sensitive lines.

    Full Text Available Resumen Una de las características del conflicto armado colombiano es el asesinato de civiles por parte de miembros de organismos de seguridad del Estado. Estos justifican sus acciones acusándolos de participar en una estrategia subversiva liderada por el Partido Comunista Colombiano. Esta, a su vez, se origina supuestamente en la guerra revolucionaria, antítesis de la guerra clásica. En Colombia, quien con mayor profundidad abordó el fenómeno de la guerra revolucionaria fue el oficial Fernando Landazábal Reyes. Este artículo pretende mostrar los principales rasgos de la guerra revolucionaria, desde la perspectiva del mencionado militar y la manera como pudo haber repercutido en el conflicto armado colombiano.Abstract One of the characteristics of the armed Colombian conflict is the murder of civilians by the members of organisms of national security, who accuse those they kill of participating in a subversive strategy led by the Colombian Communist Party, which in turn supposedly originates in the revolutionary war, antithesis of the classic war. In Colombia, the phenomenon of revolutionary war has been approached in depth by the officer Fernando Landazábal Reyes. This article tries to show the principal features of the revolutionary war, from the perspective of the mentioned military man and the way since it could have reverberated in the armed colombian conflict.

    Full Text Available This article offers a reading of the poetical texts of Aníbal Núñez (Salamanca, 1944-1987 focused on the study of two of its most important images, the ruin and the crystal. 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. In conclusion, some guidelines will be proposed in order to define the poetics of time inscribed in the Spanish author’s texts.Este trabajo propone una lectura de los textos poéticos del salmantino Aníbal Núñez (1944-1987 a partir del estudio de dos de sus imágenes fundamentales, la ruina y el cristal.

    Full Text Available Many volcanic islands face freshwater stress and the situation may worsen with climate change and sea level rise. In this context, an optimum management of freshwater resources becomes crucial, but is often impeded by the lack of data. With the aim of investigating the hydrogeological settings of Southern San Cristóbal Island (Galapagos, we conducted an helicopter-borne, transient electromagnetic survey with the SkyTEM system. It provided unprecedented insights in the 3-D resistivity structure of this extinct basaltic shield. Combined with remote sensing and fieldwork, it allowed the definition of the first hydrogeological conceptual model of the island. Springs are fed by a series of perched aquifers overlying a regional basal aquifer subject to seawater intrusion. Dykes, evidenced by alignments of eruptive cones at the surface, correspond to sharp sub-vertical contrasts in resistivity in the subsurface, and impound groundwater in a summit channel. Combined with geomorphological observations, airborne electromagnetics is shown to be a useful tool for hydrogeological exploratory studies in complex, poorly known environments. It allows optimal development of land-based geophysical surveys and drilling campaigns.

    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.

    The parasitoid Spalangia endius Walker is an efficient controller of Dipteran pupae, such as Musca domestica L. The entomopathogenic fungus Beauveria bassiana (Bals.) Vuil. is a regulator of insect populations, including these synanthropic pests. The aim of this work was to explore the possibilities of utilizing both agents in a combined form for the biocontrol of the domestic fly. Recently formed M. domestica pupae were inoculated by immersion in conidia suspension (10(8) conidia/ml) with two strains of B. bassiana (Bb6 and Bb10). The inoculated pupae were offered to the female parasitoid. In one bioassay they were offered pupae inoculated a single day and in other, pupae inoculated the following day as well. In both bioassays non inoculated (control) pupae were offered to the parasitoids until their death. Thirty females of S. endius were used for each strain and bioassay. From the study of the parasitoid offspring, life tables were built and the reproduction net rate (R(0)) and intrinsic natural increase (r(m)) were obtained among other demographic parameters; the parasitism percentages and sex ratios were also analyzed. B. bassiana did not affect significantly the biodemography of the parasitoid when pupae were inoculated a single time. On the other hand the R0 and the rm were smaller than that of the control without the fungus when pupae were inoculated twice, although sporulation was not observed in the cadavers of S. endius.

    Full Text Available El objetivo de este estudio consistió en examinar el efecto de la localización del partido, el nivel del oponente y el marcador sobre las estrategias de posesión del balón en un equipo de fútbol profesional. Para ello fueron analizados 27 partidos de la temporada 2005-2006 de la Liga Española de Fútbol utilizando un sistema computerizado de análisis del juego. Los partidos fueron divididos en episodios de juego de acuerdo con la evolución del marcador. Los resultados del análisis de regresión lineal muestran que la posesión del balón en global y el porcentaje de minutos que el equipo observado tuvo la posesión del balón en cada zona del campo de juego (zona defensiva 1/3, zona media 1/3 y zona ofensiva 1/3 estuvieron condicionados por las variables de situación analizadas, bien de forma independiente o de forma interactiva. La combinación de estas variables y sus interacciones puede ser utilizada para construir modelos que estimen la posesión del balón en el fútbol. Los hallazgos ponen en evidencia la necesidad para los entrenadores e investigadores de tener en cuenta los potenciales efectos independientes e interactivos de la localización del partido, el nivel del oponente y el marcador durante la evaluación del rendimiento de los equipos y los jugadores.

Patients: 44 patients (33 had undergone a previous capsule endoscopy with indications for obscure digestive hemorrhage, angiodysplasia, Peutz-Jeghers syndrome, ulcer, suspected Crohn's disease, tumors, and refractory celiac disease. Results: we carried out enteroscopy studies in 44 patients by the oral route and, in 6 additional patients, by both the oral and anal routes. We reached the ileon with the oral route in all cases but one (jejunal stenosis, and in 4 cases out of 7 with the anal route, with an average duration of 73 minutes. We found angiodysplasia in 19 cases, as well as NSAID-related enteropathy, Crohn's disease, diverticulosis, and Waldenström's disease. We performed biopsies in 31% of cases with diagnoses of adenocarcinoma, lymphangiectasia secondary to tumor in celiac disease, and Whipple's disease. We treated 19 patients with angiodysplasia (1 to 20 synchronous lesions with argon, and 4 patients with polyps using polipectomy (sporadic polyps or Peutz-Jeghers syndrome. A retained capsule in one patient with stenosis was removed. Conclusions: double-balloon enteroscopy is a useful and effective technique in the diagnosis and treatment of small intestine diseases, thus complementing capsule endoscopy.

    Introduced rodents are responsible for ecosystem changes in islands around the world. In the Galapagos archipelago, their effects on the native flora and fauna are adverse, including the extinction of endemic rodents in some islands and the reduction in the reproductive success of the Galapagos petrel (Pterodroma phaeopygia) in its nesting zones. Understanding the feeding behavior of introduced rodents and their trophic interactions with native and non-native species on islands, can assist in the design of management strategies and conservation plans of invasive and endemic species respectively. Four petrel nesting colonies were monitored during June 2013 on San Cristóbal Island (El Plátano, El Junco, San Joaquín, and La Comuna). The feeding habits of black rats were evaluated by analyzing stomach contents and stable isotopes in hair. Three species of introduced rodents were captured. R. rattus was the most abundant at all sites (n=43, capture success (CS) = 55.8%), followed by the house mouse, Mus musculus (n = 17, CS = 37.8%), and the Norwegian rat, R. norvegicus (n = 4, CS = 4.5%), captured only at La Comuna. The omnivorous black rat ate mostly plants (98%) and arthropods (2%). Intact seeds of Miconia robinsoniana were the main food at all sites (relative abundance=72.1%, present in 95% of the analyzed stomachs), showing the black rats' possible role in the archipelago as endemic seed dispersers. There was no evidence of petrel's intake; however, its possible consumption is not discarded at all. The δ15N and δ13C analysis corroborated the primarily herbivorous diet of black rats. The isotopic signatures of the three rodent species reflect the inter- and intra-specific differential use of food resources. Black rat showed a wider diet in La Comuna, which was related to a lower availability of its primary prey and its ability to adapt to the available resources in its habitat. PMID:25984724

    Chemical insecticides are broadly applied to control diamondback moth, Plutella xylostella (L.). Diamondback moth is a major pest of cruciferous worldwide, and resistance of this pest to insecticide has been often reported. Thus, this research investigated the interactions among the fungi Metarhizium anisopliae (Metsch.) Sorok., Beauveria bassiana (Bals.) Vuill., and the larval-pupal parasitoid Oomyzus sokolowskii (Kurdjumov) before and after application of the fungi on DBM larvae offered to the parasitoid. The experiment was carried out at 26+/-l degreeC, 75+/- 5% RH and 12h photophase using a completely randomized design, with eight treatments with six replications each. The isolates E9 of M. anisopliae and ESALQ 447 of B. bassiana, were used at the concentration of 10(7) conidia ml(-1). The results showed that M. anisopliae and B. bassiana reduced the parasitism of P. xylostella by O. sokolowskii. Additive effects were found on the mortality of P. xylostella with the different combinations among the fungi and parasitoid, except for the treatment B. bassiana inoculated 24h before exposition of the larvae to O. sokolowskii. The isolates were more efficacious when applied after exposition of the larvae to the parasitoid. The efficiency of O. sokolowskii was negatively influenced by the presence of the fungi, mainly when the fungi were applied 24h before diamondback's larvae were exposed to the parasitoid. The association of the fungi with the parasitoid presents potential to be tested in field. The use of these natural enemies in the integrated management of P. xylostella may economically improve the cabbage productive system, especially for organic farming. PMID:17348136

Even though Columbus lived during the Renaissance period, the mentality carried in his project is closer to some modern philosophers such as Descartes and Hobbes, who from rationality and individualism constitute a change of time. The hypothesis that Columbus is a modern person is sustained with evidence in the reasons he explained to defend his project from the Spanish court and especially the final agreement, "the capitulation", in which rationality and individualism took precedence over divine or medieval considerations. The rationalist mentality of Columbus prefigures that from modern businessman who does not stitch without thimble.El descubrimiento de América, impulsado por Cristóbal Colón, es una empresa  de la Modernidad, entendida esta como la mentalidad moderna desplegada en el sistema capitalista. Si bien es cierto que Colón, por la época en que vivió, se ubica  dentro del Renacimiento, la mentalidad con que fue llevada a cabo su iniciativa está más cerca de modernos como Descartes y Hobbes, quienes, a partir de la racionalidad y el individualismo, configuran un cambio de época. La hipótesis de que Colón es un moderno se sustenta con muchas evidencias en las razones que construyó para defender su proyecto ante la corte española y especialmente en el acuerdo final, “la capitulación”, en donde la racionalidad y el individualismo priman sobre consideraciones divinas o medievales. La mentalidad racionalista de Colón prefigura la del empresario moderno que no da puntada sin dedal.

    San Cristóbal volcano is the highest and one of the most active volcanoes in Nicaragua. Its persistently high activity during the past decade is characterized by strong degassing and almost annual VEI 1-2 explosions, which present a threat to the local communities. Following an eruption on 8 September 2012, the intervals between eruptions decreased significantly, which we interpret as the start of a new eruptive phase. We present here the results of semi-continuous SO2 flux measurements covering a period of 18 months, obtained by two scanning UV-DOAS instruments installed as a part of the network for observation of volcanic and atmospheric change project, and the results of real-time seismic amplitude measurements (RSAM) data. Our data comprise a series of small to moderately explosive events in December 2012, June 2013 and February 2014, which were accompanied by increased gas emissions and seismicity. In order to approach an early warning strategy, we present a statistical method for the joint analysis of gas flux and seismic data, by using continuous wavelet transform and cross-wavelet transform (XWT) methods. This analysis shows that the XWT coefficients of SO2 flux and RSAM are in good agreement with the occurrence of eruptive events and thus may be used to indicate magma ascent into the volcano edifice. Such multi-parameter surveillance efforts can be useful for the interpretation and surveillance of possible eruptive events and could thus be used by local institutions for the prediction of upcoming volcanic unrest.

    Full Text Available We present an interpretation of the epigraphic information transmitted by Polybius about the bronzes containing the first treaties between Carthage and Rome, and the one of the Temple of Hera Lacinia about Hannibal’s defensive strategy, which allows us to propose a hypothesis to reconstruct the provincial organization of Carthage in Libya and Iberia, as part of the struggle for hegemony in the western Mediterranean. This proposal also represents a turning point in the knowledge of the pre-Roman peoples of the Iberian Peninsula and we believe will provide a better understanding of the situation and organization of Carthage before the Second Punic War, its position in front of Rome and of their consecutive processes of the conquest of Iberia.Presentamos una interpretación de la información epigráfica transmitida por Polibio de los bronces que contenían los primeros tratados entre Cartago y Roma, y el del templo de Hera Lacinia, acerca de la estrategia defensiva de Aníbal, que permite proponer una hipótesis para reconstruir la organización provincial de Cartago en Libia y en Iberia, en el marco de la lucha por la hegemonía en el Mediterráneo occidental. Esta propuesta también supone un punto de inflexión en el conocimiento de los pueblos prerromanos de la Península Ibérica y creemos que permitirá conocer mejor tanto la situación y organización de Cartago antes de la Segunda Guerra Púnica, como su posición frente a Roma y sus consecutivos procesos de conquista de Iberia.

    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.

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.

    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.

    Full Text Available O presente trabalho tem por finalidade apresentar as etapas de um projeto para construção de uma bomba-balâo para contrapulsação aórtica. Desenvolveram-se três protótipos, sendo que os dois primeiros utilizavam ar comprimido e vácuo hospitalares para insuflação e deflação do cateter-balão. Esses dois protótipos apresentavam como diferenças fundamentais: o tipo de dispositivo que captava o sinal luminoso da onda R do ECG utilizado para a sincronização do bombeamento; o tipo de válvula solenóide e os componentes eletrônicos de maior resolução utilizados no segundo protótipo. O terceiro e atual protótipo passou a obter o sinal da onda R diretamente da saída de cardioversão do monitor de ECG e substituiu o ar comprimió e o vácuo hospitalares, além das válvulas solenóides, por uma bomba eletromagnética. Está em fase de resolução o problema de deflação tardia que ainda ocorre no sistema.The present paper presents the project and construction of a balloon-pump for aortic counterpulsation. Three experimental models were developed, the first two using hospital air and vacuum lines for inflation and deflation of the balloon catheter. These two inicial models diffères among themselves in the mechanism used to capture the light signal corresponding to the R wave of the ECG, which was used to sincronize the pumping. The solenoid valve and electronic components were of higher resolution in the second model. The third and present model recieves the R wave signal from the cardioversor adaptor of ECG monitor and the hospital vacuum and air lines along with the solenoid valve were substituted by an electromagnetic pump. The problems related to late deflation that have ocurred in the system are still in study. Emphasis is given on the importance of this research, which has incremented knowledge for the construction of other medical equipment, mainly in the area of respiratory care.

    Glutathione S-transferase (GST) from the liver and gill tissues of Ağrı Balık Lake Trout (also known as Black Sea Trout) Salmo trutta labrax was characterized and purified, and the toxic effects of some heavy metal ions on the enzyme's activity were analyzed. Liver GST was purified 930 times, resulting in 56% yield using glutathione-agarose affinity chromatography and a specific activity of 60.87 endotoxin units (EU)/mg protein. Using the same procedure, gill GST was purified 576 times, resulting in a 60% yield and specific activity of 46.8 EU/mg protein. The purity check of the purified enzymes was determined with sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). Optimal pH, ionic strength, and stable pH were found for each tissue, and separate KM and Vmax values were determined for reduced glutathione and 2,4-dinitrochlorobenzene substrates. Heavy metal ions that have toxic effects on living organisms and are known to contribute to environmental pollution were selected, and their in vitro effects on enzyme activity were analyzed. The IC50 values and Ki constants of those metal ions showing an inhibitory effect on GST activity were determined. PMID:26075414

  6. In vivo assessments of pulmonary toxicity following exposure to inhaled fibers: Utilization of bronchoalvelolar lavage (BAL) and fixed lung tissue to assess fiber deposition patterns and early cellular responses

    International Nuclear Information System (INIS)

    There is a great need for the development of a rapid and reliable short-term bioassay to evaluate the toxicity of inhaled particles and fibers. We have hypothesized that the pulmonary toxicity of particulates can be assessed by exposing animals to aerosols for short duration (1-5 days) and measuring a variety of biochemical, cellular and histopathologic endpoints at several time point postexposure. In this presentation, we have attempted to test the efficacy of our shortterm inhalation bioassay, by exposing rats to various doses of either α-quartz silica or crocidolite asbestos, known fibrogenic materials, as well as wollastonite fibers or carbonyl iron particles. Following exposures, fluids and cells from sham and dust exposed rats were recovered by lavage (BAL) and measured for enzymes, protein, cellular differentials an cytochemical analysis. Pulmonary macrophages were cultured and studied for morphology, chemotaxis and phagocytosis. The lungs of additional animals were fixed for light microscopic histopathology and autoradiography, as well as scanning and transmission electron microscopy, where particle/fiber deposition and translocation were assessed. The results from biochemical and cellular studies support the conclusion that silica and crocidolite are substantially more toxic to the lungs than wollastonite or carbonyl iron, and serves to lend support to the establishment of this method as a reliable shortterm bioassay for evaluating the lung toxicity following inhalation of a variety of inhaled materials

    Full Text Available Examining the reasons why women’s presentation in senior management levels and strategically important positions is lower compared to men constitutes the aim of this study. Conducting a literature survey, the concept of “Glass Ceiling” has been explained and the obstacles confronting women in preferment to senior management positions have been presented depending on the related studies held in Turkey and other countries. In the application part of the study, under the light of the findings from the literature, a survey covering 200 employees, of whom 103 male and 97 female, has been conducted in order to find out about the opinions of employees in Balıkesir on the obstacles in question. The findings have revealed that the limited horizon of leadership and managerial capability, excessive familial responsibilities, and the “queen bee” syndrome are the main obstacles that hamper women in the progress towards senior level managerial positions.

    Full Text Available OBJETIVO: A neoproliferação intimal e o remodelamento têm sido implicados como os maiores fatores causadores de reestenose. O objetivo deste trabalho é estudar a ação da L-arginina por via oral, nesses dois fatores, após lesão por balão, em artérias ilíacas de coelhos hipercolesterolêmicos. MÉTODOS: Foram utilizados dezenove coelhos, que foram divididos em dois grupos: controle (GC e arginina (GA, respectivamente com dezenove e dezessete artérias estudadas. Os animais foram submetidos a lesão por balão de angioplastia, em suas artérias ilíacas, quinze dias após início de dieta hipercolesterolêmica a 2%. A seguir, os animais do GA passaram a receber uma solução de L-arginina, por via oral, na dose de 1 g/kg/dia. Após o sacrifício, no 15º dia após a lesão por balão, procedeu-se a cortes histológicos das artérias, as quais foram coradas e fixadas. Utilizou-se como representativa do desenvolvimento da lesão a razão da área da neoíntima (em mm² pela camada média (em mm². Por sua vez, a razão da área total do vaso em sua porção medial (de maior contato com o balão pela área total do vaso no segmento referencial (de menor contato com o balão foi a definidora do remodelamento. RESULTADOS: A média do espessamento neointimal (NI/M foi de 0,8151±0,2201 no GC e de 0,3296±0,1133 no GA. Não houve diferença entre os tipos de remodelamento entre os dois grupos estudados. CONCLUSÃO: No modelo experimental utilizado, a L-arginina foi capaz de reduzir o espessamento intimal em coelhos hipercolesterolêmicos e não teve ação sobre o remodelamento arterial.OBJECTIVE: It has been implied that neointimal proliferation and remodeling are the major causes of restenosis. The objective of this study is to assess the effect of orally administered L-arginine on these two factors in hypercholesterolemic rabbits that had suffered an injury to their iliac arteries caused by a catheter balloon.

    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 In the treatment of complex paraclinoidal and giant cavernous aneurysms, preservation of the patency of the internal carotid artery (ICA is not always possible, and therapeutic occlusion of the carotid is still an important option for their management. A complete preoperative evaluation of the carotid reserve circulation, including the use of temporary balloon occlusion test and single photon emission computerized tomography (SPECT should be included in the current paradigms of paraclinoidal and intracavernous aneurysms management. We present a series of fifteen patients with sixteen giant or complex carotid cavernous or ophthalmic aneurysms that were treated following a protocol for our preoperative decision-making analysis. Extracranial to intracranial saphenous vein bypass was reserved to the cases where carotid occlusion would be associated with high risk of ischemic complications and was performed in three patients. Besides the difficulties in dealing with those complex aneurysms, good clinical outcome was possible in our experience with the designed paradigm.No tratamento de aneurismas paraclinoideos complexos e cavernosos gigantes, a preservação da patência vascular nem sempre é possível, e a oclusão terapêutica da carótida ainda é uma opção importante no seu manejo.

    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.

    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.

OBJETIVOS: Descrever a mortalidade de pacientes que necessitaram utilizar balão intra-aórtico (BIAo no trans ou pós-operatório de cirurgia cardíaca, identificando variáveis pré-operatórias associadas a pior desfecho, assim como descrever as complicações pós-operatórias e a sobrevida em médio prazo. MÉTODOS: Estudo de coorte retrospectivo incluindo 80 casos consecutivos entre janeiro/2009 e setembro/2011. Os pacientes possuíam, em média, 62,9 ± 11,3 anos e 58,8% eram do sexo masculino. Na amostra, 81,3% dos pacientes eram hipertensos, 50% tinham infarto do miocárdio prévio e 38,8%, insuficiência cardíaca NYHA III/IV. A principal cirurgia realizada foi a revascularização miocárdica isolada (37,5%.

    While amongst the most luminous objects in the universe, many details regarding the inner structure of quasars remain unknown. One such area is the mechanism promoting increased polarisation in the broad absorption line troughs of certain quasars. This study shows how microlensing can be used to differentiate between two popular models that explain such polarisation through a realistic computational analysis. By examining a statistical ensemble of correlation data between two observables (namely image brightness and polarisation of the flux coming from the quasar), it was found that through spectropolarimetric monitoring it would be possible to discern between a model with an external scattering region and a model without one.

    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.

    We show that time variations in the UV ionizing continuum of quasars, on scales of $\\sim$1 year, affect the dynamic structure of the plasmas responsible for low ionization broad absorption lines. Variations of the ionizing continuum produce non-equilibrium photoionization conditions over a significant fraction of the absorbing clouds and supersonically moving ionization fronts. When the flux drops the contraction of the ionized region drives a supersonic cooling front towards the radiation so...

As pessoas ouvem expressões, tais como "globalização" e "abertura ao capital estrangeiro", muitas vezes sem entender o significado disso. No campo das artes, a exemplo da dança, muitos bailarinos ainda costumam construir um mundo a parte, distante das mudanças que ocorrem na realidade em que vivem. Torna-se cada vez mais necessária compreender melhor essa realidade, conhecer um pouco de história da dança, a fim de que se tenha elementos para questionar o sentido de práticas pedagógicas e artísticas em dança na sociedade em que vivemos.

    We present optical R-band light curves of the gravitationally lensed quasar SBS1520+530 derived from data obtained at the Nordic Optical Telescope. A time delay of 130+/-3 days (1 sigma) is determined from the light curves. In addition, spectra of SBS1520+530 obtained at the Keck Observatory are spatially deconvolved in order to extract the spectrum of the faint lensing galaxy, free of any contamination by the light from the bright quasar images. This spectrum indicates a lens redshift z=0.717, in agreement with one of the absorption systems found in the quasar spectra. The best mass model of the system includes a second nearby galaxy and a cluster of galaxies in addition to the main lensing galaxy. Adopting this model and an Omega=0.3, Lambda=0.7 cosmology, our time-delay measurement yields a Hubble constant of H_0=51+/- 9, km/s/Mpc (1 sigma error).

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.

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.

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.

  10. Structural phase stability and bonding behavior of BAlH5 (B=Mg,Ba) from first-principles calculations

    International Nuclear Information System (INIS)

    The ground-state structures of MgAlH5 and BaAlH5 have been subjected to full structural optimization considering 50 different potential atomic arrangements as inputs for accurate density-functional total-energy calculations. The experimentally known crystal structure and structural parameters for BaAlH5 are reproduced, and the crystal structure of MgAlH5 is predicted. At 0 K and ambient pressures MgAlH5 and BaAlH5 crystallize in monoclinic (CaFeF5 type, P21/c) and orthorhombic (prototype, Pna21) structures, respectively. In addition to the ground-state MgAlH5 phase (here designated α-MgAlH5), it is also predicted a metastable modification (termed β-MgAlH5, CaCrF5 type, Cc). The structures comprise isolated, highly distorted AlH6 octahedra, which form one-dimensional chains along the [001] direction. In α- and β-MgAlH5 these chains are fairly linear, while BaAlH5 exhibits distinct zigzag chains. α-MgAlH5 and BaAlH5 are nonmetallic phases with estimated band gaps of 2.48 and 2.73 eV, respectively. Analyses of the density of states, charge density, Mulliken population, and Born effective charge indicate that the interaction between Al and H is polar covalent blended with an ionic woof, while Ba and Mg can be considered as virtually divalent ions

    The ground-state structures of MgAlH5 and BaAlH5 have been subjected to full structural optimization considering 50 different potential atomic arrangements as inputs for accurate density-functional total-energy calculations. The experimentally known crystal structure and structural parameters for BaAlH5 are reproduced, and the crystal structure of MgAlH5 is predicted. At 0K and ambient pressures MgAlH5 and BaAlH5 crystallize in monoclinic ( CaFeF5 type, P21/c ) and orthorhombic (prototype, Pna21 ) structures, respectively. In addition to the ground-state MgAlH5 phase (here designated α-MgAlH5 ), it is also predicted a metastable modification (termed β-MgAlH5 , CaCrF5 type, Cc ). The structures comprise isolated, highly distorted AlH6 octahedra, which form one-dimensional chains along the [001] direction. In α - and β-MgAlH5 these chains are fairly linear, while BaAlH5 exhibits distinct zigzag chains. α-MgAlH5 and BaAlH5 are nonmetallic phases with estimated band gaps of 2.48 and 2.73eV , respectively. Analyses of the density of states, charge density, Mulliken population, and Born effective charge indicate that the interaction between Al and H is polar covalent blended with an ionic woof, while Ba and Mg can be considered as virtually divalent ions.

    Full Text Available The paper deals with micro- and macrostructural static and dynamic narrative characteristics in specifically language-impaired (SLI Russian-speaking preschool children and their typically-developing (TD peers. The study was based on experimental data that included storytelling and retelling elicited by means of wordless picture sequences. First, individual measures of story structure, episode com- pleteness, internal state terms, story productivity, lexical diversity, and syntactic complexity, as well as the percentage of linguistic dysfluencies and errors, were evaluated and compared between the experimental and control groups. Second, the impact of such factors as session (1st vs. 2nd, story complexity, and mode (telling vs. retelling on the dynamic variation of micro- and macrostructural narrative measures was evaluated. Our results highlighted essential dynamic differences between the samples from the perspective of narrative structure, structural complexity, grammaticality, and vocabulary.

    Characterizing hydrological extreme events and assessing their societal impacts is perpetual challenge for hydrologists. Climate models predict that anticipated temperature rise leads to an intensification of the hydrological cycle and to a corresponding increase in the reoccurrence and the severity of extreme events. The societal impact of the hydrological extremes are interlinked with anthropogenic activities therefore the damages to manmade infrastructures are rarely a good measure of the extreme events' magnitudes. Extreme events are rare by definition therefore detecting change in their distributions requires long-term observational records. Currently, only in-situ monitoring time series has the temporal extent necessary for assessing the reoccurrence probabilities of extreme events, but they frequently lack the spatial coverage. Satellite remote sensing is often advocated to provide the required spatial coverage, but satellites have to compromise between spatial and temporal resolutions. Furthermore, the retrieval algorithms are often as complex as comparable hydrological models with similar degree of uncertainties in their parameterization and the validity of the final data products. In addition, anticipated changes over time in the reoccurrence frequencies of extreme events invalidates the stationarity assumption, which is the basis for using past observations to predict the probabilities future extreme events. Probably the best approach to provide more robust predictions of extreme events is the integration of the available data (in-situ and remote sensing) in a comprehensive data assimilation frameworks built on top of adequate hydrological modeling platforms. Our presentation will provide an overview of the current state of hydrological models to support data assimilations and the viable pathways to integrate in-situ and remote sensing observations for flood predictions. We will demonstrate the use of socio-economic data in combination with hydrological data assimilation to assess the resiliency to extreme flood events.

    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.

  4. The effect of Hf substitution for Zr on glass forming ability and magnetic property of FeCoZrMoBAlY bulk metallic glasses

    International Nuclear Information System (INIS)

    Bulk metallic glasses (BMGs) Fe61Co6Zr8-xHfxMo7B15Al1Y2 (x = 0-8) have been produced by copper mold casting technique using industrial raw materials. The effect of substitution of Hf for Zr on the glass forming ability (GFA) and the magnetic property has been studied by X-ray diffraction (XRD), differential scanning calorimetry (DSC) and superconducting quantum interference device (SQUID). It was found that the substitution of an appropriate amount of Hf for Zr can improve the GFA of the base alloy Fe61Co6Zr8Mo7B15Al1Y2, as demonstrated by the increase in reduced glass transition temperature Trg (=Tg/Tl) and GFA parameters of γ (=Tx/Tg + Tl) and δ (=Tx/Tl - Tg). The Fe61Co6Zr5Hf3Mo7B15Al1Y2 alloy exhibits the highest GFA with the largest Trg (0.612) and δ (1.633), and can cast a fully amorphous rod in 3 mm diameter. The substitution of Hf for Zr also enhances the magnetic properties, as verified by the increase in saturation magnetization (Ms) in the alloy of Fe61Co6Zr3Hf5Mo7B15Al1Y2, whose Ms is approximately 1.5 times higher than that of the base alloy (x = 0) at room temperature. Finally, the effect of the substitution of Hf for Zr on glass forming ability and magnetic properties is discussed

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

    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.

    Full Text Available The objective of the present work was to evaluate the effect of the entomopathogen fungi Baeuveria bassiana and Metarhizium anisioplae of the Prodiplosis longifila pupas, in order to reduce the adult population of this insect. The treatments consisted on the application of two different propagel concentrations (mycel and conidia of each entomopathogen. One of these concentration was 1x106 propagels/ml (obtained from the total amount of conidia collected of 25 kg of rice colonized by the entomopathogen; and the other one, was 1x107 propagels/ml (obtained from the total amount of conidia collected of 40 kg of rice colonized by the entomopathogen. As a check a non application treatment was considered. The applications were trough the irrigation system and started 15 days after the end of harvest and were repeated each five days during a month, coincident with the period of most falls of pupas of the soil. As a result Baeuveria bassiana at 1x107 propagels/ml shown 53.4 % of the total pupas colonized by the entomopathogen, which allows indicating B. bassiana as a promissory biocontrol of this specie

    Full Text Available The in vitro susceptibility of Amblyomma cajennense engorged females to some isolated of the fungus Beauveria bassiana and Metarhizium anisopliae was verified and lethal concentrations (LC 50 and LC 90 were calculated. The females were dived in conidia suspensions for five minutes, and kept in climatically controlled chambers BOD under 27° C and 80% relative humidity. Each bioassay had four treatments in concentrations of 10(5,10(6,10(7e10(8 conidia/ml. A control group was also used. The following characteristics were evaluated: weight and period of oviposition, indexes of reproductive and nutritional efficiency and percentage of microbiological control. A dose dependent negative effect was observed in ticks treated with the suspension. All isolates tested cause a negative effect on in vitro tests of engorged females of A. cajennense, suggesting its potential for microbiological control of tick's species.

    The nature and origin of Broad Absorption Line (BAL) quasars and their relationship to non-BAL quasars are an open question. The BAL quasars are probably normal quasars seen along a particular line of sight. Alternatively, they are young or recently refueled. The high resolution radio morphology of BAL quasars is very important to understand the radio properties of BAL quasars. We present VLBA observations at L and C bands for a sample of BAL quasars. The observations will help us to explore the VLBI radio properties, and distinguish the present models of explaining BAL phenomena.

    Fernando Santos Granero

    2005-12-01

    Full Text Available The article analyzes the phenomenon of child sorcery, that is, of children accused of being sorcerers, among the Arawakan peoples of eastern Peru. 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.

    Full Text Available The network of who passes the ball to whom describes the tactical configurations in the development of a soccer match (Bundio y Conde, 2007; Cotta, Mora, Merelo-Molina y Merelo, 2011. The team is analyzed as a network, with players as nodes and passes as directed edges. The patterns of interaction between players reveal emergent processes that transcend traditional individual statistics. Although the first applications of network analysis to soccer use the matrix of all the passes during the match, the differentiation of the relationships between players depending on the type of work carried out shows more clearly the tactical elements of the game (Maya Jariego y Bohórquez, 2011. To illustrate this we used data from Real Betis in the 2005 Copa del Rey final, as well as the match in the 2007 final. Both centrality measures and nonparametric tests showed a clear differentiation between the passing network and the adaptation network. The results allow interpreting the tactical development of the match. Finally we compare the network analysis of the match with a description based in individual players statistics.

    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.

    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。

    2016-01-01

    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...

  1. A CHANDRA SURVEY OF THE X-RAY PROPERTIES OF BROAD ABSORPTION LINE RADIO-LOUD QUASARS

    International Nuclear Information System (INIS)

    This work presents the results of a Chandra study of 21 broad absorption line (BAL) radio-loud quasars (RLQs). We conducted a Chandra snapshot survey of 12 bright BAL RLQs selected from Sloan Digital Sky Survey Data/Faint Images of the Radio Sky data and possessing a wide range of radio and C IV absorption properties. Optical spectra were obtained nearly contemporaneously with the Hobby-Eberly Telescope; no strong flux or BAL variability was seen between epochs. In addition to the snapshot targets, we include in our sample nine additional BAL RLQs possessing archival Chandra coverage. We compare the properties of (predominantly high-ionization) BAL RLQs to those of non-BAL RLQs as well as to BAL radio-quiet quasars (RQQs) and non-BAL RQQs for context. All 12 snapshots and 8/9 archival BAL RLQs are detected, with observed X-ray luminosities less than those of non-BAL RLQs having comparable optical/UV luminosities by typical factors of 4.1-8.5. (BAL RLQs are also X-ray weak by typical factors of 2.0-4.5 relative to non-BAL RLQs having both comparable optical/UV and radio luminosities.) However, BAL RLQs are not as X-ray weak relative to non-BAL RLQs as are BAL RQQs relative to non-BAL RQQs. While some BAL RLQs have harder X-ray spectra than typical non-BAL RLQs, some have hardness ratios consistent with those of non-BAL RLQs, and there does not appear to be a correlation between X-ray weakness and spectral hardness, in contrast to the situation for BAL RQQs. RLQs are expected to have X-ray continuum contributions from both accretion-disk corona and small-scale jet emission. While the entire X-ray continuum in BAL RLQs cannot be obscured to the same degree as in BAL RQQs, we calculate that the jet is likely partially covered in many BAL RLQs. We comment briefly on implications for geometries and source ages in BAL RLQs.

    We have used data from the Herschel-ATLAS at 250, 350 and 500 \\mu m to determine the far-infrared (FIR) properties of 50 Broad Absorption Line Quasars (BAL QSOs). Our sample contains 49 high-ionization BAL QSOs (HiBALs) and 1 low-ionization BAL QSO (LoBAL) which are compared against a sample of 329 non-BAL QSOs. These samples are matched over the redshift range 1.5 \\leq z 5 sigma level. We calculate star-formation rates (SFR) for our individually detected HiBAL QSOs and the non-detected LoBAL QSO as well as average SFRs for the BAL and non-BAL QSO samples based on stacking the Herschel data. We find no difference between the HiBAL and non-BAL QSO samples in the FIR, even when separated based on differing BAL QSO classifications. Using Mrk 231 as a template, the weighted mean SFR is estimated to be \\approx240\\pm21 M_{\\odot} yr^{-1} for the full sample, although this figure should be treated as an upper limit if AGN-heated dust makes a contribution to the FIR emission.

    Broad absorption lines (BALs), seen in a small fraction of both the radio-quiet and radio-loud quasar populations, are probably caused by the outflow of gas with high velocities and are part of the accretion process. The presence of BALs is due to a geometrical effect and/or it is connected with the quasar evolution. Using the final release of FIRST survey combined with a catalog of BAL QSOs from SDSS/DR3, we have constructed a new sample of compact radio-loud BAL QSOs, which constitutes the majority of radio-loud BAL QSOs. The main goal of this project is to study the origin of BALs by analysis of the BAL QSOs radio morphology, orientation, and jet evolution using the European VLBI Network (EVN) at 1.6 GHz and the Very Long Baseline Array (VLBA) at 5 and 8.4 GHz.

    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 C iv 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 76 additional BAL troughs and find that the majority of BALs are stable to within about 3% of their mean velocities. The lack of widespread acceleration/deceleration could indicate that the gas producing most BALs is located at large radii from the central black hole and/or is not currently strongly interacting with ambient material within the host galaxy along our line of sight.

    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.

    We consider whether broad absorption line quasars (BAL QSOs) and narrow-line Seyfert 1 galaxies (NLS1s) are similar, as suggested by Brandt and Gallagher and Boroson. 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/L{sub Edd}, although BAL QSOs have slightly lower L/L{sub Edd}. BAL QSOs and NLS1s in general have high Fe ii/Hβ and low [O iii]/Hβ ratios following the classic “Boroson and Green” eigenvector 1 relation. We also found that the mass accretion rates M-dot of BAL QSOs and NLS1s are more similar than previously thought, although some BAL QSOs exhibit extreme mass accretion rates of more than 10 M{sub ⊙} yr{sup −1}. 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−σ plot, we find that BAL QSOs contain fully developed black holes. Applying a principal component analysis to our sample, we find eigenvector 1 to correspond to the Eddington ratio L/L{sub Edd}, and eigenvector 2 to black hole mass.

    2012-01-01

    Broad absorption line (BAL) quasars probe the high velocity gas ejected by luminous accreting black holes. BAL variability timescales place constraints on the size, location, and dynamics of the emitting and absorbing gas near the supermassive black hole. We present multi-epoch spectroscopy of seventeen BAL QSOs from the Sloan Digital Sky Survey (SDSS) using the Fred Lawrence Whipple Observatory's 1.5m telescope's FAST Spectrograph. These objects were identified as BALs in SDSS, observed with Chandra, and then monitored with FAST at observed-frame cadences of 1, 3, 9, 27, and 81 days, as well as 1 and 2 years. We also monitor a set of non-BAL quasars with matched redshift and luminosity as controls. We identify significant variability in the BALs, particularly at the 1 and 2 year cadences, and use its magnitude and frequency to constrain the outflows impacting the broad absorption line region.

  14. THE INTRINSIC FRACTIONS AND RADIO PROPERTIES OF LOW-IONIZATION BROAD ABSORPTION LINE QUASARS

    International Nuclear Information System (INIS)

    Low-ionization (Mg II, Fe II, and Fe III) broad absorption line quasars (LoBALs) probe a relatively obscured quasar population and could be at an early evolutionary stage for quasars. We study the intrinsic fractions of LoBALs using the Sloan Digital Sky Survey (SDSS), Two Micron All Sky Survey, and Faint Images of the Radio Sky at Twenty cm survey. We find that the LoBAL fractions of the near-infrared (NIR) and radio samples are approximately 5-7 times higher than those measured in the optical sample. This suggests that the fractions measured in the NIR and radio bands are closer to the intrinsic fractions of the populations, and that the optical fractions are significantly biased due to obscuration effects, similar to high-ionization broad absorption line quasars (HiBALs). Considering a population of obscured quasars that do not enter the SDSS, which could have a much higher LoBAL fraction, we expect that the intrinsic fraction of LoBALs could be even higher. We also find that the LoBAL fractions decrease with increasing radio luminosities, again, similarly to HiBALs. In addition, we find evidence for increasing fractions of LoBALs toward higher NIR luminosities, especially for FeLoBALs with a fraction of ∼18% at MKs< -31 mag. This population of NIR-luminous LoBALs may be at an early evolutionary stage of quasar evolution. To interpret the data, we use a luminosity-dependent model for LoBALs that yields significantly better fits than those from a pure geometric model.

    Pores in the membrane of a bioartificial liver (BAL) allow it to function as a semipermeable barrier between its contents (i.e., liver cells) and components of the recipient's immune system. This study is designed to assess the influence of pore size on immune response to a BAL containing porcine hepatocytes. Sixteen healthy dogs were divided into four groups (four dogs per group) based on pore size of the BAL membrane and level of exposure to porcine hepatocytes. Group 1 dogs were administered porcine hepatocytes by intraperitoneal injection and served as positive controls. Group 2 dogs were exposed to porcine hepatocytes in a large-pore (200-nm) BAL, and group 3 dogs were exposed to porcine hepatocytes in a small-pore (10-nm) BAL. Group 4 dogs were exposed to a no-cell (unloaded) BAL and served as negative controls. Intraperitoneal injection of hepatocytes or 3 hours of BAL hemoperfusion was performed day 0 and 3 weeks later on day 21. Biochemical, humoral, and cellular measures of immune response were collected until day 44. The initiation of BAL hemoperfusion was associated with a rapid decline in CH(50) levels of complement and transient neutropenia and thrombocytopenia during all BAL exposures. Xenoreactive antibody response to BAL was increased by use of membranes with large pores and secondary exposures. Skin testing on day 42 showed a delayed-type hypersensitivity response to porcine hepatocytes that also correlated with level of previous antigen exposure. BAL treatment was associated with both immediate and elicited immunologic responses. The immediate response was transient and not influenced by membrane pore size, whereas elicited responses were influenced by pore size of the BAL during previous exposures. PMID:12619028

    Given the xenogeneic immune reaction relevant to the molecular weight cutoff of the membrane of a bioartificial liver (BAL) system, we investigated the influence of membrane molecular weight cutoff in our BAL system in this study. Acute liver failure in beagles was induced by d-galactosamine administration. Eight beagles were divided into two groups by the membrane molecular weight cutoff of the plasma component separator. Group 1 beagles were treated with BAL containing 200 kDa retention rating membrane. Group 2 beagles were treated with BAL containing 1200 kDa retention rating membrane. Each group underwent two 6-h BAL treatments that were performed on day 1 and day 21. The hemodynamic and hematologic response, humoral immune responses, and cytotoxic immune response to BAL therapy were studied before and after treatments. All beagles remained hemodynamically and hematologically stable during BAL treatments. BAL treatment was associated with a significant decline in levels of complement; however, a longer time of level maintenance was observed in Group 2. Group 2 beagles experienced a significant increase in levels of IgG and IgM after two BAL treatments. Significant levels of canine proteins were detected in BAL medium from Group 2; only trace levels of canine proteins were detected in BAL medium from Group 1. The posttreatment viability of co-culture cells in Group 2 was lower compared with Group 1, and the viability of co-culture cells after treatments was associated with deposition of canine proteins on the cells. Xenogeneic immune response was influenced by membrane molecular weight cutoff in the BAL. PMID:21819437

Aim : Study incidence and subtypes of BAL, correlate with age, morphology, and cytogenetic findings and correlate the clinico-hematological data with the treatment response. St Jude′s and the EGIL′s criteria have been compared for their diagnostic and clinical relevance. Material and Methods : Diagnosis was based on WHO classification, including clinical details, morphology, cytochemistry, immunophenotyping, and molecular genetics. We included those cases, which fulfilled the European Group for the Immunological Characterization of Acute Leukemia′s (EGIL′s scoring system criteria for the diagnosis of BAL, as per recommendation of the WHO classification. Results : There were 32 patients diagnosed with BAL, based on EGIL′s criteria. Incidence of BAL was 1.2%. B-Myeloid (14 cases followed by T-Myeloid BAL (13 cases were the commonest subtypes. Polymorphous population of blasts (16 cases was commonly associated with T-Myeloid BAL (10 cases. BCR ABL fusion positivity was a common cytogenetic abnormality (seven cases. Fifteen patients received chemotherapy; eight achieved complete remission (CR at the end of the induction period. Conclusions : Pediatric BAL and T-B lymphoid BAL have a better prognosis. A comprehensive panel of reagents is required, including cytoplasmic markers; to diagnose BAL. St Jude′s criteria is a simple, easy, and cost-effective method to diagnose BAL. The outcome-related prognostic factors include age, HLA-DR, CD34 negativity, and subtype of BAL. BCR-ABL expression is an important prognostic factor, as these cases will be labeled as Chronic myeloid leukemia (CML in blast crisis with biphenotypic expression and treated accordingly.

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.

    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.

    We present the results of EVN+MERLIN very long baseline interferometry (VLBI) polarization observations of eight broad absorption line (BAL) quasars at 1.6 GHz, including four low-ionization BAL quasars (LoBALs) and four high-ionization BAL quasars (HiBALs) with either steep or flat spectra on Very Large Array (VLA) scales. Only one steep-spectrum source, J1122+3124, shows two-sided structure on the scale of 2 kpc. The other four steep-spectrum sources and three flat-spectrum sources display either an unresolved image or a core-jet structure on scales of less than 300 pc. In all cases, the marginally resolved core is the dominant radio component. Linear polarization in the cores has been detected in the range of a few to 10 per cent. Polarization, together with high brightness temperatures (from 2 × 109 to 5 × 1010K), suggests a synchrotron origin for the radio emission. There is no apparent difference in the radio morphologies or polarization between low-ionization and high-ionization BAL quasi-stellar objects (QSOs) or between flat- and steep-spectrum sources. We discuss the orientation of BAL QSOs with both flat and steep spectra, and consider a possible evolutionary scenario for BAL QSOs. In this scenario, BAL QSOs are probably a young population of radio sources that are compact steep spectrum or GHz peaked radio source analogues at the low end of radio power.

    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...

    Our objective was to identify false-positive serum and bronchoalveolar lavage (BAL) fluid galactomannan (GM) tests caused by various antibiotics commonly used in general practice. Serum and BAL samples from patients who did not have the diagnostic criteria of invasive aspergillosis and received different antibiotics were prospectively analyzed for GM. Serum and BAL samples were also collected from patients who did not receive antibiotics. At the cut-off index of >or=0.5, false-positive serum results were found in patients who received amoxicillin-clavulanate, piperacillin-tazobactam, cefepime, and cefoperazone-sulbactam (26.7%, 58.3%, 14.3%, and 66.7%, respectively). Fungal colonization in BAL samples had a higher BAL GM than those without fungal colonization. In 71 patients who had a negative BAL culture for fungi, at the cut-off value of >or=1.0, false-positive BAL fluid results were found in patients who received amoxicillin-clavulanate (27.3%), piperacillin-tazobactam (50%), cefepime (16.7%), carbapenem (45.5%), and ceftriaxone (45.5%). False-positive serum and BAL GM assays were also detected in patients who did not receive any antibiotics. In summary, this study demonstrates the false-positive GM levels in serum and BAL caused by beta-lactam antibiotics that are commonly used in general practice. Physicians should be aware of this possible interference. PMID:20192889

  19. AN INFRARED EXCESS IDENTIFIED IN RADIO-LOUD BROAD ABSORPTION LINE QUASARS

    International Nuclear Information System (INIS)

    If broad absorption line (BAL) quasars represent a high-covering-fraction evolutionary state (even if this is not the sole factor governing the presence of BALs), it is expected that they should show an excess of mid-infrared radiation compared to normal quasars. Some previous studies have suggested that this is not the case. We perform the first analysis of the IR properties of radio-loud BAL quasars, using IR data from WISE and optical (rest-frame ultraviolet) data from SDSS, and compare the BAL quasar sample with a well-matched sample of unabsorbed quasars. We find a statistically significant excess in the mid- to near-infrared luminosities of BAL quasars, particularly at rest-frame wavelengths of 1.5 and 4 μm. Our sample was previously used to show that BALs are observed along many lines of sight toward quasars, but with an overabundance of more edge-on sources, suggesting that orientation factors into the appearance of BALs. The evidence here—of a difference in IR luminosities between BAL quasars and unabsorbed quasars—can be ascribed to evolution. This suggests that a merging of the current BAL paradigms is needed to fully describe the class.

  2. Unveiling the X-ray/UV properties of AGN winds using Broad and mini-Broad Absorption Line Quasars

    2015-07-01

    BAL/mini-BALs are observed in the UV spectra of ˜ 20-30% of optically selected AGN as broad absorption troughs blueshifted by several thousands km/s, indicative of powerful nuclear winds. They could be representative of the average AGN if their winds cover only 20-30% of the continuum source, and/or represent an evolutionary state analogous to the high-soft state of BHB, when the jet emission is quenched and strong X-ray absorbing equatorial disk winds are virtually ubiquitous. High-quality, possibly time-resolved X-ray/UV studies are crucial to assess the global amount and 'character' of absorption in BAL/mini-BAL QSOs and to constrain the physical mechanism responsible for the launch and acceleration of their winds, therefore placing them in the broader context of AGN geometry and evolution. I will review here the known X-ray properties of BAL/mini-BAL QSOs, and present new results from a comprehensive X-ray spectral analysis of all the Palomar-Green BAL/mini-BAL QSOs with available XMM-Newton observations, for a total of 51 pointings of 14 different sources. These will include the most recent results from a high-quality simultaneous XMM/HST observational campaign on the mini-BAL QSO PG 1126-041, that unveiled with stunning details the X-ray/UV connection in action in an AGN disk wind through correlated X-ray/UV absorption variability.

    A double immunofluorescence analysis of CD4+ cell population from bronchoalveolar lavage (BAL) fluid samples of patients with active pulmonary sarcoidosis was carried out. The results showed that, unlike BAL and peripheral blood CD4+ cells of healthy subjects, almost all BAL CD4+ cells of the patients highly express, besides CDw29 antigen, LFA-1 and ICAM-1 adhesion molecules. The co-expression of these molecules on BAL CD4+ cells during high intensity sarcoid alveolitis could represent a marker of immunological memory. The relevant pathogenetic and clinical implications of this observation are discussed. PMID:2199744

    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...

  5. Lung damage induced by butylated hydroxytoluene in mice. Biochemical, cellular, and morphologic characterization.

    Science.gov (United States)

    Smith, L J

    1984-11-01

    This study was designed to characterize the biochemical, cellular, and morphologic events produced in mice by butylated hydroxytoluene (BHT) and to relate these events to changes in extracellular angiotensin-converting enzyme (ACE) activity. On Day 1 after the administration of BHT, bronchoalveolar lavage (BAL) ACE activity increased 4-fold (p less than 0.001), its specific activity relative to BAL protein increased 3-fold (p less than 0.001), and both type 1 cell damage and endothelial cell damage were detected by electron microscopy. The early increase in BAL ACE activity preceded changes in plasma ACE levels, BAL cell number, protein, lactate, and lactate dehydrogenase (LDH) activity in both plasma and BAL, and the ACE content of alveolar macrophages. On Day 2, BAL ACE activity increased 9-fold, BAL protein increased 4-fold (p less than 0.001), BAL LDH activity increased 34% (p less than 0.05), and the BAL cell count doubled (p less than 0.01). Changes in each animal's appearance, body weight, wet and dry lung weights, and plasma ACE levels occurred between Days 3 and 5. The BAL differential cell count, which consisted of greater than 95% macrophages in uninjured mice, did not change until Day 5 when there was a small increase in polymorphonuclear leukocytes (PMN). On Day 7, the number of PMN peaked, and some of the other measures of lung injury began returning toward normal. These results indicate that BAL ACE activity is a sensitive, early marker of BHT-induced lung injury, which appears to reflect damage to the cells of the alveolar-capillary barrier. In addition, PMN do not appear to play a major role in this model of lung injury. Because of its effects on angiotensin, bradykinin, and prostaglandins, the early release of ACE from damaged cells may modulate the subsequent injury. PMID:6093659

    Full Text Available BACKGROUND: Fine Needle Aspiration Cytology (FNAC, Bronchoalveolar Lavage (BAL and Brush Cytology are important diagnostic tools for evaluation of pulmonary lesions. Considering the limitations of these procedures correlation of these cytological techniques may help in improving accuracy and increasing the diagnostic yield. AIM: To determine the role of FNAC, Brush and BAL Cytology in pulmonary lesions and to correlate the efficacy of FNAC with Brush and BAL Cytology. MATERIALS AND METHODS: This prospective study was conducted on 78 patients with radiologically demonstrable pulmonary lesions in the department of pathology and Dr ML Chest Hospital, GSVM Medical College, Kanpur over a period from nov2011-july2013. The cases selected had to give consent for the procedure. Bronchoalveolar lavage, bronchial brush sample were taken and FNAC was done in the cases. RESULTS: In present study 78 cases of pulmonary lesions were subjected to FNAC and/ or Bronchoalveolar lavage and brush cytology. Among them 49 cases were selected in which all three procedures were done. The sensitivity and specificity for detecting lung tumors by FNAC was 96.29% and 95.45% which was more than that of BAL cytology (84.61%, 91.30% and Brush cytology (81.48%, 95.45%. FNA correlates with Brush and BAL cytology in 78.57% of malignant lesions. Among malignant lesions 84.61% of BAL and Brush cytology correlates with FNA for diagnosis of squamous cell carcinoma. FNA correlates with 66.67% of brush and 83.37% of BAL fluid cytology for diagnosis of adenocarcinoma. BAL and Brush both correlates with FNA in 83.33% cases of small cell carcinoma. Overall 85.71% of BAL and 82.14% of brush smear cytology correlates with FNA cytology for diagnosis of lung cancers. CONCLUSIONS: FNA, BAL and Brush cytology provide a high yield for evaluation of pulmonary lesions. BAL fluid and brush cytology correlated well with FNAC for diagnosis of lung cancers.

    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.

    We present a catalog of 5039 broad absorption line (BAL) quasars (QSOs) in the Sloan Digital Sky Survey (SDSS) Data Release 5 (DR5) QSO catalog that have absorption troughs covering a continuous velocity range >= 2000 km/s. We have fit ultraviolet (UV) continua and line emission in each case, enabling us to report common diagnostics of BAL strengths and velocities in the range -25,000 to 0 km/s for SiIV $\\lambda$1400, CIV $\\lambda$1549, AlIII $\\lambda$1857, and MgII $\\lambda$2799. We calculate these diagnostics using the spectrum listed in the DR5 QSO catalog, and also for spectra from additional SDSS observing epochs when available. In cases where BAL QSOs have been observed with Chandra or XMM-Newton, we report the X-ray monochromatic luminosities of these sources. We confirm and extend previous findings that BAL QSOs are more strongly reddened in the rest-frame UV than non-BAL QSOs and that BAL QSOs are relatively X-ray weak compared to non-BAL QSOs. The observed BAL fraction is dependent on the spectral s...

    2016-01-01

    Full Text Available Background: Bronchoalveolar lavage (BAL has gained acceptance for diagnosis of Interstitial lung disease (ILD. The advent of high-resolution computed tomography (HRCT has reduced the clinical utility of BAL. This work has utilized the recommendations of the American Thoracic Society (ATS to optimize BAL and the findings have been associated with clinical examination and HRCT to precisely narrow down the cause of ILD. Materials and Methods: BAL was performed on ILD suspects at the target site chosen based on HRCT. The procedure, transport, processing, and analysis of BAL fluid were performed as per the ATS guidelines. The clinical data, HRCT findings and BAL report were used to narrow down the diagnosis of ILD. The statistical analysis was performed to assess the significance. Results: The BAL procedure was optimized as per the recommendations of the ATS. In a cohort of 50 patients, Idiopathic pulmonary fibrosis, (8 hypersensitivity pneumonitis, (17 connective tissue disorder, (9 sarcoidosis, (3 pneumoconiosis, (5 acute respiratory distress syndrome, (2 eosinophilic lung disease (2 and lymphangitic carcinomatosa, (2 aspiration bronchiolitis (1 and pulmonary histiocytosis (1 were diagnosed. Statistically significant variation in differential counts was found in different ILDs. The different ILDs were classified based on the criteria described by the ATS. Clinical Significance: BAL along with clinical and HRCT findings improved the diagnostic accuracy by incorporating, the acute or chronic nature of the disease and the cause for acute exacerbation, which helped in the better management of ILDs.

    Quasar outflows are plausible candidates for AGN feedback processes influencing the host galaxy and may explain the established correlations between the supermassive black hole (SMBH) and the surrounding bulge. In order to better understand feedback and the physical conditions of the outflowing gas, observational constraints on absorber kinematics and energetics are needed. We are utilizing multiple epoch, rest frame UV quasar spectra to establish limits on outflow locations and total column densities for the purpose of estimating wind kinetic energies and momenta. We are also investigating the variability patterns of broad absorption lines (BALs) and mini-BALs across a range of ionization states to probe underlying connections between the various classes of absorbers. This work employs observations from the Sloan Digital Sky Survey, Hobby Eberly Telescope, and MDM observatory. We detect BAL variability in 3 out of 12 FeLoBAL quasars over multiple year timescales and conclude that the variable absorbers lie within tens of parsecs of the SMBH based on interpretations of the Fe II and Mg II BALS. We also measure significant BAL changes across daily to yearly timescales in a sample of 71 quasars with plausible detections of the P V 1117,1128 BAL. Detecting phosphorus in absorption is notable because it traces high column density outflows and is therefore relevant for studying AGN feedback. Constraints on outflow energetics and other selected results will be presented.

    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.

    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 ...

  2. 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 ...

  3. Monitoring the variability of intrinsic absorption lines in quasar spectra , ,

    International Nuclear Information System (INIS)

    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 yr (1-3.5 yr 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 or 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 BALs. 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 ∼103-105 cm–3 and upper limits on the distance of the absorbers from the central engine of the order of a few kiloparsecs. Motivated by the observed variability properties, we suggest that mini-BALs can vary because of fluctuations of the ionizing continuum or changes in partial coverage while NALs can vary primarily because of changes in partial coverage.

    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...

  5. What is the significance of the conservation of electric charge Q?

    International Nuclear Information System (INIS)

    Conservation of electric charge Q is a universal law in the sense that it should be conserved in any interaction, known or yet unknown. However Q should not be considered as a simple number but as the half sum of two irreducible quantities BAL= A-L (A is the baryonic number and L is the leptonic number) and total flavour TF. Conservation of electric charge implies obviously conservation of Q (considered as a simple number) but also BAL and TF. We verify that electromagnetism and strong interaction which conserve Q, A and L and all individual flavours conserve obviously BAL and TF; likely weak interaction which conserves Q, A and L conserves also BAL and TF. However conservation of BAL does not imply necessarily conservation of A and L. In effect ΔBAL=0 has another solution ΔA= ΔL= ± 1 which points to a possible solution to explain how a material and neutral universe could arise evolving from A=0 L=0 Q=0 state to A>0 Q=0 state through a process which would conserve BAL and TF without conserving separately A and L.

  6. X-RAYS FROM A RADIO-LOUD COMPACT BROAD ABSORPTION LINE QUASAR 1045+352 AND THE NATURE OF OUTFLOWS IN RADIO-LOUD BROAD ABSORPTION LINE QUASARS

    International Nuclear Information System (INIS)

    We present new results on X-ray properties of radio-loud broad absorption line (BAL) quasars and focus on broadband spectral properties of a high-ionization BAL (HiBAL) compact steep spectrum (CSS) radio-loud quasar 1045+352. This HiBAL quasar has a very complex radio morphology indicating either strong interactions between a radio jet and the surrounding interstellar medium or a possible re-start of the jet activity. We detected 1045+352 quasar in a short 5 ksec Chandra ACIS-S observation. We applied theoretical models to explain spectral energy distribution of 1045+352 and argue that non-thermal, inverse-Compton (IC) emission from the innermost parts of the radio jet can account for a large fraction of the observed X-ray emission. In our analysis, we also consider a scenario in which the observed X-ray emission from radio-loud BAL quasars can be a sum of IC jet X-ray emission and optically thin corona X-ray emission. We compiled a sample of radio-loud BAL quasars that were observed in X-rays to date and report no correlation between their X-ray and radio luminosity. However, the radio-loud BAL quasars show a large range of X-ray luminosities and absorption columns. This is consistent with the results obtained earlier for radio-quiet BAL quasars and may indicate an orientation effect in BAL quasars or more complex dependence between X-ray emission, radio emission, and an orientation based on the radio morphology.

  7. Comparison of glycerolisation with cryopreservation methods on HIV-1 inactivation

    International Nuclear Information System (INIS)

    Cryopreservation and glycerolisation are two successful long-term preservation methods for human cadaveric donor skin, which is used in the treatment of bum patients. High concentrations of glycerol has been shown to be antibacterial and virucidal. Because fear of possible transmission of HIV-1 following allograft transplantation, this study was undertaken to investigate whether HIV can be effectively eliminated from skin explants. HIV-1 Ba-L, which has been shown to infect monocytes in skin explants and also dendritic cells, was. For the experiments we used cell-free virus, exogenously HIV infected peripheral blood mononuclear cells (PBMCs) and exogenously HIV infected cadaver split skin. Different concentrations of glycerol at various temperatures and the glycerolisation procedure as used by the Euro Skin Bank were used to determine the effects on HIV-1 Ba-L infectivity. For the cryopreservation technique we used 10% DMSO and a controlled rate freezer. HIV-1 Ba-L transfer was determined by adding uninfected PBMCs to the infected material and reverse transcriptase was measured. Cell-free HIV-1 Ba-L was not inactivated by 50% glycerol but was effectively inactivated within 30 minutes by 70% and 85% glycerol at 4 degree C, room temperature and 37 degree C. In contrast, cell-free HIV-1 Ba-L was not inactivated by cryopreservation. Most importantly, we have shown that HIV-1 Ba-L present in split skin is inactivated by incubating skin in 70% glycerol for three hours at 37-C. HIV in exogenously infected skin was not inactivated by cryopreservation. High concentrations of glycerol effectively inactivates free HIV-1 Ba-L and intracellular HIV-1 Ba-L. Also the current glycerolisation procedure carried out by the Euro Skin Bank effectively inactivates infectious virus. However, the cryopreservation technique did not show any reduction in HIV-1 Ba-L infectivity

    If broad absorption line (BAL) quasars represent a high covering fraction evolutionary state (even if this is not the sole factor governing the presence of BALs), it is expected that they should show an excess of mid-infrared radiation compared to normal quasars. Some previous studies have suggested that this is not the case. We perform the first analysis of the IR properties of radio-loud BAL quasars, using IR data from WISE and optical (rest-frame ultraviolet) data from SDSS, and compare th...

  12. Phenotypic instability of Arabidopsis alleles affecting a disease Resistance gene cluster

    2008-04-01

    Full Text Available Abstract Background Three mutations in Arabidopsis thaliana strain Columbia – cpr1, snc1, and bal – map to the RPP5 locus, which contains a cluster of disease Resistance genes. The similar phenotypes, gene expression patterns, and genetic interactions observed in these mutants are related to constitutive activation of pathogen defense signaling. However, these mutant alleles respond differently to various conditions. Exposure to mutagens, such as ethyl methanesulfonate (EMS and γ-irradiation, induce high frequency phenotypic instability of the bal allele. In addition, a fraction of the bal and cpr1 alleles segregated from bal × cpr1 F1 hybrids also show signs of phenotypic instability. To gain more insight into the mechanism of phenotypic instability of the bal and cpr1 mutations, we systematically compared the behavior of these unusual alleles with that of the missense gain-of-function snc1 allele in response to DNA damage or passage through F1 hybrids. Results We found that the cpr1 allele is similar to the bal allele in its unstable behavior after EMS mutagenesis. For both the bal and cpr1 mutants, destabilization of phenotypes was observed in more than 10% of EMS-treated plants in the M1 generation. In addition, exceptions to simple Mendelian inheritance were identified in the M2 generation. Like cpr1 × bal F1 hybrids, cpr1 × snc1 F1 hybrids and bal × snc1 F1 hybrids exhibited dwarf morphology. While only dwarf F2 plants were produced from bal × snc1 F1 hybrids, about 10% wild-type F2 progeny were produced from cpr1 × snc1 F1 hybrids, as well as from cpr1 × bal hybrids. Segregation analysis suggested that the cpr1 allele in cpr1 × snc1 crosses was destabilized during the late F1 generation to early F2 generation. Conclusion With exposure to EMS or different F1 hybrid contexts, phenotypic instability is induced for the bal and cpr1 alleles, but not for the snc1 allele. Our results suggest that the RPP5 locus can adopt different

    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.

    International Nuclear Information System (INIS)

    Results of cytological analysis of bronchoalveolar lavage (BAL) fluid were compared with clinical diagnoses in dogs that presented with signs of respiratory disease to referral hospitals. Of 68 dogs in which a clinical diagnosis was possible, BAL cytological findings were considered definitive for the diagnosis in 17 cases (25%), supportive of the diagnosis in 34 cases (50%), and not helpful in 17 cases (25%). Findings were most often considered supportive of or definitive for the clinical diagnosis in dogs with alveolar or bronchial radiographic patterns, or the presence of pulmonary masses. BAL results among lung lobes differed in 23 of 63 dogs (37%) with diffuse radiographic patterns. Tracheal wash cytology differed from BAL fluid cytology in 45 of 66 dogs (68%).

    Narrow absorption line (NAL) outflows are an important yet poorly understood part of the quasar outflow phenomenon. We discuss one particular NAL outflow that has high speeds, time variability, and moderate ionizations like typical BAL flows, at an estimated location just ~5 pc from the quasar. It also has a total column density and line widths (internal velocity dispersions) ~100 times smaller than BALs, with no substantial X-ray absorption. We argue that radiative shielding (in the form of an X-ray/warm absorber) is not critical for the outflow acceleration and that the moderate ionizations occur in dense substructures that have an overall small volume filling factor in the flow. We also present new estimates of the overall incidence of quasar outflow lines; e.g., ~43% of bright quasars have a C IV NAL outflow while ~68% have a C IV outflow line of any variety (NAL, BAL, or mini-BAL).

    Full Text Available The purpose of this study was to determine the presence of recurrent airway obstruction (RAO through bronchoalveolar lavage (BAL in a group of twenty Colombian native horses with respiratory symptoms. Each animal underwent a clinical examination in order to corroborate the respiratory disturbance and later perform the BAL. The results obtained showed that 65% of the animals under study tested positive for RAO, based on the clinical and BAL results, and that, among the total number of animals that tested positive, 61.5% suffered a severe form of such condition. We also found an association between the number of neutrophils and the color of the BAL fluid, and an inverse relationship between cell cytology of macrophages and neutrophils. It is concluded that the Colombian native horse, like other horse breeds, suffers from RAO, sometimes severely, related to predisposing factors such as accommodation and stabling.

    Hubble Space Telescope Faint Object Spectrograph (HST FOS) observations have shown that the spectrum of the low-redshift (z(sub em) approximately equal to 0.384) QSO PG 0043+039 exhibits weak broad absorption lines (BALs). The BALs were discovered during the course of UV spectrophotometry made for the HST Quasar Absorption Line Key Project. The HST data are analyzed along with ground-based optical and IUE spectrophotometry. The object is found to have a number of atypical properties relative to normal non-BAL QSOs. The observed continuum is atypical in the sense that it is much weaker than that of a normal optically selected QSO at rest wavelengths approximately less than 2200 A. Intrinsic reddening of E(B-V) approximately equal to 0.11 mag by dust similar to that found in the SMC at the redshift of PG 0043+039 conservatively accounts for the observed continuum shape moderately well. These observed characteristics are typical of low-ionization BAL QSOs, but convincing evidence for BALs due to low-ionization transitions of Mg II, Al III, Al II, or C II does not exist. Therefore, this object may be a misaligned BAL QSO having many of the characteristics of low-ionization BAL QSOs with the sight line passing through a putative dusty region, but evidently missing clouds of high enough column density to produce observable low-ionization BALs. If the intrinsic dust-extinction model is correct, the observations suggest that the dust is not confined to the presumably higher density, low-ionization BAL clouds, but that it has drifted to nearby high-ionization BAL regions. We also consider other possible mechanisms for producing the shape of the continuous energy distribution which cannot be ruled out. We compare the Fe II emission in PG 0043+039 with that in another Key Project QSO, NGC 2841-UB 3, which has optical Fe II emission comparable in strength to that in PG 0043+039, but has anomalously weak UV Fe II emission.

    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.

    Balò's sclerosis is considered a rare variant of multiple sclerosis characterized by demyelination with concentric rings. Advanced magnetic resonance studies allow nowadays early diagnosis and prompt treatment. However, the pathophysiology of lesion evolution is still matter of debate, as detailed in our literature review. Based on a clear-cut Balò's lesion analysis, we describe early changes in DWI and ADC values within the different layers, favoring the concept of a centrifugal growth. PMID:25405537

    Full Text Available Abstract Background Macrophages have been implicated in the pathogenesis of COPD. M1 and M2 macrophages constitute subpopulations displaying pro- and anti-inflammatory properties. We hypothesized that smoking cessation affects macrophage heterogeneity in the lung of patients with COPD. Our aim was to study macrophage heterogeneity using the M2-marker CD163 and selected pro- and anti-inflammatory mediators in bronchoalveolar lavage (BAL fluid and induced sputum from current smokers and ex-smokers with COPD. Methods 114 COPD patients (72 current smokers; 42 ex-smokers, median smoking cessation 3.5 years were studied cross-sectionally and underwent sputum induction (M/F 99/15, age 62 ± 8 [mean ± SD] years, 42 (31-55 [median (range] packyears, post-bronchodilator FEV1 63 ± 9% predicted, no steroids past 6 months. BAL was collected from 71 patients. CD163+ macrophages were quantified in BAL and sputum cytospins. Pro- and anti-inflammatory mediators were measured in BAL and sputum supernatants. Results Ex-smokers with COPD had a higher percentage, but lower number of CD163+ macrophages in BAL than current smokers (83.5% and 68.0%, p = 0.04; 5.6 and 20.1 ×104/ml, p = 0.001 respectively. The percentage CD163+ M2 macrophages was higher in BAL compared to sputum (74.0% and 30.3%, p + BAL macrophages (Rs = 0.38, p = 0.003. No significant differences were found between smokers and ex-smokers in the levels of pro-inflammatory (IL-6 and IL-8, and anti-inflammatory (elafin, and Secretory Leukocyte Protease Inhibitor [SLPI] mediators in BAL and sputum. Conclusions Our data suggest that smoking cessation partially changes the macrophage polarization in vivo in the periphery of the lung towards an anti-inflammatory phenotype, which is not accompanied by a decrease in inflammatory parameters.

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

    Directory of Open Access Journals (Sweden)

    Jonas Christian Schupp

    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.

    Roughly 1/3rd of immune competent patients will reactivate latent cytomegalovirus (CMV) during critical illness. There are no standard methods to detect reactivation, and some investigators have postulated that presence of DNA in BAL fluid is indicative of viral replication. To test this hypothesis, we used a murine model that allows inclusion of matched healthy controls which is not possible in human studies. BALB/c mice infected with Smith-murine CMV or PBS (mock) had BAL evaluated 7, 14, or 21 days after acute infections, during latency, or during bacterial sepsis. Plaque assay, PCR, and rtPCR were performed on BALs and concomitantly obtained lung tissue. BAL cellular compositions, including tetramer evaluation of CMV-specific T cells were evaluated by flow cytometry. CMV DNA were detected in BAL at all time-points during acute infection, becoming undetectable in all mice during latency, then were detected again during bacterial sepsis, peaking 3 weeks after onset. mCMV specific T-cells were most numerous in BAL after acute viral infections, decreasing to low levels during latency, then fluctuating during bacterial sepsis. Specifically, mCMV-specific T-cells contracted at sepsis onset, expanding 2-4 weeks post-sepsis, presumably in response to increased viral loads at that time point. Altogether, our results support the use of BAL PCR for the diagnosis of CMV replication in immune competent hosts. Additionally, we demonstrate dynamic changes in CMV-specific T cells that occur in BAL during CMV infection and during sepsis induced viral reactivation. J. Med.

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

    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.

    Purpose Matrix metalloproteinases (MMPs) have been implicated in the pathogenesis of pulmonary fibrosis. To understand the role of MMP-2 and MMP-9 in pulmonary fibrosis, we evaluated the sequential dynamic change and different cellular sources of the 2 MMPs along the time course and their differential expression in the bronchoalveolar lavage (BAL) fluid and in the lung parenchyma of the bleomycin-induced pulmonary fibrosis models in rats. Materials and Methods The level of MMPs in BAL fluid o...

    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 (EA...

  20. Weak Hard X-Ray Emission from Broad Absorption Line Quasars: Evidence for Intrinsic X-Ray Weakness

    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 330 times weaker than...... 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 (Γeff ≈ 1.8) for this sample disfavors Compton-thick absorption in general. The uniform hard X...... 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...

    The mechanism of tissue injury after exposure to air pollution particles is not known. The biological effect has been postulated to be mediated via an oxidative stress catalyzed by metals present in particulate matter (PM). We utilized a transgenic (Tg) mouse model that overexpresses extracellular superoxide dismutase (EC-SOD) to test the hypothesis that lung injury after exposure to PM results from an oxidative stress in the lower respiratory tract. Wild-type (Wt) and Tg mice were intratracheally instilled with either saline or 50 microg of residual oil fly ash (ROFA). Twenty-four hours later, specimens were obtained and included bronchoalveolar lavage (BAL) and lung for both homogenization and light histopathology. After ROFA exposure, EC-SOD Tg mice showed a significant reduction in BAL total cell counts (composed primarily of neutrophils) and BAL total protein compared with Wt. EC-SOD animals also demonstrated diminished concentrations of inflammatory mediators in BAL. There was no statistically significant difference in BAL lipid peroxidation; however, EC-SOD mice had lower concentrations of oxidized glutathione in the BAL. We conclude that enhanced EC-SOD expression decreased both lung inflammation and damage after exposure to ROFA. This supports a participation of oxidative stress in the inflammatory injury after PM exposure rather than reflecting a response to metals alone. PMID:12060579

  2. Transient C IV broad absorption lines in radio-detected QSOs

    We study the transient (i.e. emerging or disappearing) C IV broad absorption line (BAL) components in 50 radio-detected QSOs using multi-epoch spectra available in Sloan Digital Sky Survey Data Release-10. We report the detection of six BALQSOs having at least one distinct transient C IV absorption component. Based on the structure function analysis of optical light curves, we suggest that the transient absorption is unlikely to be triggered by continuum variations. Transient absorption components usually have low C IV equivalent widths (10 000 km s-1) and typically occur over rest-frame time-scales >800 d. The detection rate of transient C IV absorption seen in our sample is higher than that reported in the literature. Using a control sample of QSOs, we show that this difference is most likely due to the longer monitoring time-scale of sources in our sample while the effect of small number statistics cannot be ignored. Thus, in order to establish the role played by radio jets in driving the BAL outflows, we need a larger sample of radio-detected BALs monitored over more than 3 yr in the QSO's rest frame. We also find that the transient phenomenon in radio-detected and radio-quiet BALs does not depend on any of the QSO properties, i.e. the Eddington ratio, black hole mass, bolometric luminosity and optical-to-IR colours. All this suggests that transient BAL phenomenon is simply the extreme case of BAL variability.

  3. FR-II Broad Absorption Line Quasars and the Life Cycle of Quasars

    Gregg, M D; Becker, R H; de Vries, W

    2006-01-05

    By combining the Sloan Digitized Sky Survey Third Data Release quasar list with the VLA FIRST survey, we have identified five objects having both broad absorption lines in their optical spectra and FR-II radio morphologies. We identify an additional example of this class from the FIRST Bright Quasar Survey, J1408+3054. Including the original FR-II-BAL object, J1016+5209, brings the number of such objects to eight. These quasars are relatively rare; finding this small handful has required the 45,000-large quasar sample of SDSS. The FR-II-BAL quasars exhibit a significant anti-correlation between radio-loudness and the strength of the BAL features. This is easily accounted for by the evolutionary picture in which quasars emerge from cocoons of BAL-producing material which stifle the development of radio jets and lobes. There is no such simple explanation for the observed properties of FR-II-BALs in the unification-by-orientation model of quasars. The rarity of the FR-II-BAL class implies that the two phases do not coexist for very long in a single quasar, perhaps less than 10{sup 5} years, with the combined FR-II, high ionization broad absorption phase being even shorter by another factor of 10 or more.

    Full Text Available Biphenotypic acute leukemia (BAL is defined as the existence of multiple antigen coexpression in leukemic blasts or two different types of blast population. In this study, a patient who was first diagnosed with BAL and later with acute myeloid leukemia M1 (AML-M1 is presented. The patient was four-year-old male and had complaints about high fever, fatigue, lack of appetite, and weight loss for two months. % 96 L2 type blasts were identified in bone marrow aspiration, and positive values for CD79a, CD56, CD5, CD13, CD33, and MPO were observed in flow-cytometry. These findings, evaluated on the basis of “European Group for the Immunological Characterization of Leukemias (EGİL” criteria, suggested BAL. As the steroid treatment returned no response, the flow-cytometry findings were reevaluated based on “World Health Organization (WHO” criteria. BAL was excluded and AML M1 was considered as a diagnosis. The positive values for CD79a, CD56 , and CD5 were evaluated as coexpression. Chemotherapy was given as AML treatment, and the dramatic response was reported. This case is presented to show that, using EGİL criteria to evaluate BAL may be misleading , and thus using WHO criteria to evaluate BAL may be more appropriate.

    2007-01-01

    We have compiled the largest sample of multiwavelength spectral energy distributions (SEDs) of Broad Absorption Line (BAL) quasars to date, from the radio to the X-ray. We present new Spitzer MIPS (24, 70, and 160 micron) observations of 38 BAL quasars in addition to data from the literature and public archives. In general, the mid-infrared properties of BAL quasars are consistent with those of non-BAL quasars of comparable luminosity. In particular, the optical-to-mid-infrared luminosity ratios of the two populations are indistinguishable. We also measure or place upper limits on the contribution of star formation to the far-infrared power. Of 22 (57%) upper limits, seven quasars have sufficiently sensitive constraints to conclude that star formation likely contributes little (<20%) to their far-infrared power. The 17 BAL quasars (45%) with detected excess far-infrared emission likely host hyperluminous starbursts with L_fir,SF=10^{13-14} L_sun. Mid-infrared through X-ray composite BAL quasar SEDs are pre...

    Full Text Available Global-scale examination of protein phosphorylation in human biological fluids by phosphoproteomics approaches is an emerging area of research with potential for significant contributions towards discovery of novel biomarkers. In this pilot work, we analyzed the phosphoproteome in human bronchoalveolar lavage fluid (BAL from nondiseased subjects. The main objectives were to assess the feasibility to probe phosphorylated proteins in human BAL and to obtain the initial catalog of BAL phosphoproteins, including protein identities and exact description of their phosphorylation sites. We used a gel-free bioanalytical workflow that included whole-proteome digestion of depleted BAL proteins, enrichment of phosphopeptides by immobilized metal ion affinity chromatography (IMAC, LC-MS/MS analyses with a linear ion trap mass spectrometer, and searches of a protein sequence database to generate a panel of BAL phosphoproteins and their sites of phosphorylation. Based on sequence-diagnostic MS/MS fragmentation patterns, we identified a collection of 36 phosphopeptides that contained 26 different phosphorylation sites. These phosphopeptides mapped to 21 phosphoproteins including, for example, vimentin, plastin-2, ferritin heavy chain, kininogen-1, and others. The characterized phosphoproteins have diverse characteristics in terms of cellular origin and biological function. To the best of our knowledge, results of this study represent the first description of the human BAL phosphoproteome.

    This study examined different markers of lung immunologic and inflammatory responses to previous asbestos exposure. We performed bronchoalveolar lavage (BAL) and gallium-67 (/sup 67/Ga) lung scans and measured serum and BAL soluble interleukin-2 receptor (IL-2R) and angiotensin-converting enzyme (SACE) levels in 32 subjects with a history of significant asbestos exposure, 14 without (EXP) and 18 with (ASB) radiographic evidence of asbestosis. BAL analysis revealed increases in neutrophils in both ASB and EXP when compared to controls (P less than 0.01), which persisted after adjustment for smoking category. Although significant abnormalities of macrophage and total lymphocyte profiles were not found in the study population, lymphocyte subpopulation analysis revealed elevation of BAL T4/T8 ratios in the entire study group (ASB + EXP) when compared to controls (P less than 0.05), independent of smoking category. /sup 67/Ga lung scan activity was increased in 56% of ASB and in 36% of EXP: no correlations between positive scans and different radiological and functional parameters could be found. There was no significant elevation of mean SACE, serum, or BAL IL-2R levels in any of the study categories. These data suggest that asbestos exposure may be associated with parenchymal inflammation, even in the absence of clinical criteria for asbestosis. Abnormalities of gallium uptake and of BAL analysis reflect the clinically inapparent inflammation. The increased BAL T4/T8 ratios observed suggest that abnormal local pulmonary immunoregulation may play a role in the pathogenesis of asbestos-related lung diseases.

    Full Text Available Abstract Background Excessive Th1 cells and TLRs functions are involved in the pathogenesis of Behcet's disease (BD in response to bacterial antigens. NOD2, an intracellular pathogen recognition sensor, modulates innate defence to muropeptides derived from various bacterial species. To further define a role for NOD2 in BD, we analysed NOD2 transcriptional responses in BAL-MNC from BD patients with pulmonary manifestations. Methods We analysed NOD1, NOD2, T-bet and TLRs mRNA expression with real-time polymerase chain-reaction in BAL cells obtained from 23 BD patients with pulmonary manifestations and their matched controls. Results We found that NOD2 mRNA expression was highly up-regulated in BAL cells from BD and sarcoidosis patients compared to healthy control group (P = 0.001. In BD patients, significant correlation was found between NOD2 and T-bet mRNA expression (r = 0.602; P = 0.0009. In BAL from BD patients, NOD2 and T-bet mRNA expression were significantly correlated with BAL-lymphocytes (r = 0.485, P = 0.010; r = 0684, P = 0.0001 respectively. NOD2 in BD was also correlated with TLR 2(r = 0.444; P = 0.021 and TLR 4 (r = 0.574; P = 0.001 mRNA expression. Conclusion Our results indicate that BAL-MNC from BD patients expressed NOD2 as a result of lung inflammation. TLRs and NOD2 synergize for the induction of proinflammatory cytokines. BAL inflammatory cells showed an increased Th1 situation as indicated by increased T-bet mRNA expression.

    2014-12-01

    Full Text Available BackgroundPneumonia carries significant morbidity and mortality in leukemic and bone marrow transplant patient.  The development of pulmonary infiltrates in the setting of such immunocompromise raises concern for both infectious and non-infectious etiologies, some of which are potentially treatabl.  Performing bronchoscopy provides several different options for sampling the lower respiratory tract.  Among these, bronchoalveolar lavage (BAL is especially effective at collecting samples from the alveoli and has been shown to be associated with less risk than transbonchial biops. We sought to examine the effect of antimicrobial treatment on BAL results in a large study population of leukemic and bone marrow transplant patients.Subjects and MethodsThis retrospective chart review was performed at a single academic cancer center.  A power analysis was performed to determine the appropriate sample size. The patients were selected from those who had undergone an inpatient bronchoscopy in reverse chronological order until 300 patients with either a hematopoietic stem cell transplant or hematologic malignancy were identified.  The exclusion criteria were age <18, a diagnosis of HIV or acquired immune deficiency syndrome (AIDS, or outpatient status.  Electronic medical records were reviewed and data extracted by a single investigator, CY.  Data including age, sex, cancer diagnosis, time from HSCT, leukocyte count, neutropenia in addition to medications were collected.  A normal white blood cell (WBC count was considered 4,000-12,000/mm3.  Neutropenia was defined as an absolute neutrophil count (ANC less than 500/mm3.  Medications including antibiotic duration and timing, antifungal use, immunosuppressant use or glucocorticoids were recorded. A positive BAL yield was defined as the culture identification of at least one organism known to be pathogenic in this patient population.  Candida species and coagulase negative staphylocci were considered

  12. Hubble Space Telescope Observations of the Broad Absorption Line Quasar PG 0946+301

    International Nuclear Information System (INIS)

    We analyze Hubble Space Telescope (HST) and ground-based spectra of the brightest broad absorption line (BAL) quasar in the UV: PG 0946+301. A detailed study of the absorption troughs as a function of velocity is presented, facilitated by the use of a new algorithm to solve for the optical depth as a function of velocity for multiplet lines. We find convincing evidence for saturation in parts of the troughs. This supports our previous assertion that saturation is common in BALs and therefore cast doubts on claims for very high metallicity in BAL flows. Because of the importance of BAL saturation we also discuss its evidence in other objects. In PG 0946+301 large differences in ionization as a function of velocity are detected, and our findings support the hypothesis that the line of sight intersects a number of flow components that combine to give the appearance of the whole trough. Based on the optical depth profiles, we develop a geometrical-kinematical model for the flow. We have positively identified 16 ions of eight elements (H i, C iii, C iv, N iii, N iv, N v, O iii, O iv, O v, O vi, Ne v, Ne viii, P v, Si iv, S v, S vi) and have probable identifications of Mg x and S iv. Unlike earlier analysis of IUE data, we find no evidence for BALs arising from excited ionic states in the HST spectrum of PG 0946+301. copyright copyright 1999. The American Astronomical Society

  13. Monitoring the Variability of Intrinsic Absorption Lines in Quasar Spectra

    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 present the results of EVN+MERLIN VLBI polarization observations of 8 Broad Absorption Line (BAL) quasars at 1.6 GHz, including 4 LoBALs and 4 HiBALs with either steep or flat spectra on VLA scales. Only one steep-spectrum source, J1122+3124, shows two-sided structure on the scale of 2 kpc. The other four steep-spectrum sources and three flat-spectrum sources display either an unresolved image or a core-jet structure on scales of less than three hundred parsecs. In all cases the marginally resolved core is the dominant radio component. Linear polarization in the cores has been detected in the range of a few to 10 percent. Polarization, together with high brightness temperatures (from 2*10^9-5*10^10 K), suggest a synchrotron origin for the radio emission. There is no apparent difference in the radio orphologies or polarization between low-ionization and high-ionization BAL QSOs nor between flat- and steep-spectrum sources. We discuss the orientation of BAL QSOs with both flat and steep spectra, and consider...

    Secretory leukocyte proteinase inhibitor (SLPI) and alpha1-proteinase inhibitor (alpha1(PI)) cannot fully explain the total neutrophil elastase (NE) inhibitory capacity detected in bronchoalveolar lavage (BAL) fluid, suggesting the existence of other NE inhibitor(s). In the present study, we measured the concentrations of elafin, a newly described, low-molecular-weight serine proteinase inhibitor, SLPI, and alpha1(PI) in BAL fluids from eight healthy subjects, 13 asymptomatic farmers, seven farmers with active farmer's lung (FL), and seven farmers with previous (Ex) FL. In addition to SLPI and alpha1(PI), elafin was present in BAL fluids from control subjects and asymptomatic farmers, 13 (7-31) and 12 (7-67) mmol/mol of albumin (median and range) respectively. Elafin concentration increased significantly to 105 (38-207) mmol/mol of albumin in farmers with active FL and was also elevated in farmers with Ex FL. Elafin levels were highly correlated with lung inflammatory cell numbers, especially lymphocytes, and the decrease in single-breath diffusion capacity (DLCO). Elafin and SLPI were linked to yet uncharacterized proteins in BAL fluids. In conclusion, elafin is a constituent of BAL fluid from normal subjects and is found in enhanced concentrations in FL and in farmers with lymphocytic alveolitis. This suggests that elafin may play a role in lung homeostasis and inflammation. PMID:8887613

    Bronchoalveolar lavage (BAL) fluid was analysed from 21 patients with breast cancer, stage T{sub 1}N{sub 0}M{sub 0}, who had undergone tumour resection and postoperative local irradiation (accumulated dose 56 Gy). The lavage was performed two months after radiotherapy, in the anterior part of the lingula (left side) or of the right middle lobe (right side), depending on which side had been exposed to radiation. The patients had significantly increased concentrations of fibronectin (FN) (p<0.001), hyaluronan (HA) (p<0.01) and albumin (p<0.05) in BAL fluid compared with the healthy controls (n=19). However, when the patients were separated, according to smoking history, it was obvious that the inflammatory reaction occurred entirely in the nonsmoking patient group (n=10), whilst no difference could be found between the smoking patients (n=11) and the controls. In the nonsmoking patient group, there was a sevenfold increase in BAL concentrations of FN and a threefold increase in HA. Moreover, four patients had detectable levels of procollagen III peptide in BAL, all were nonsmokers. The smoking habits of the controls had no influence on the BAL measurements. These findings indicate that smoking interferes with the radiation-induced early inflammatory connective tissue reaction of the lung. Finally, the results justify further investigation of interaction of smoking with cancer treatment, both from the view of therapy effectiveness and reduction of adverse effects. (au).

    Full Text Available There is increasing evidence that proteasomes have a biological role in the extracellular alveolar space, but inflammation could change their composition. We tested whether immunoproteasome protein-containing subpopulations are present in the alveolar space of patients with lung inflammation evoking the acute respiratory distress syndrome (ARDS. Bronchoalveolar lavage (BAL supernatants and cell pellet lysate from ARDS patients (n=28 and healthy subjects (n=10 were analyzed for the presence of immunoproteasome proteins (LMP2 and LMP7 and proteasome subtypes by western blot, chromatographic purification, and 2D-dimensional gelelectrophoresis. In all ARDS patients but not in healthy subjects LMP7 and LMP2 were observed in BAL supernatants. Proteasomes purified from pooled ARDS BAL supernatant showed an altered enzyme activity ratio. Chromatography revealed a distinct pattern with 7 proteasome subtype peaks in BAL supernatant of ARDS patients that differed from healthy subjects. Total proteasome concentration in BAL supernatant was increased in ARDS (971 ng/mL ± 1116 versus 59±25; P<0.001, and all fluorogenic substrates were hydrolyzed, albeit to a lesser extent, with inhibition by epoxomicin (P=0.0001. Thus, we identified for the first time immunoproteasome proteins and a distinct proteasomal subtype pattern in the alveolar space of ARDS patients, presumably in response to inflammation.

    High glucose concentration in the airway surface liquid (ASL) is an important feature of diabetes that predisposes to respiratory infections. We investigated the role of alveolar epithelial SGLT1 activity on ASL glucose concentration and bacterial proliferation. Non-diabetic and diabetic rats were intranasally treated with saline, isoproterenol (to increase SGLT1 activity) or phlorizin (to decrease SGLT1 activity); 2 hours later, glucose concentration and bacterial proliferation (methicillin-resistant Sthaphylococcus aureus, MRSA and Pseudomonas aeruginosa, P. aeruginosa) were analyzed in bronchoalveolar lavage (BAL); and alveolar SGLT1 was analyzed by immunohistochemistry. BAL glucose concentration and bacterial proliferation increased in diabetic animals: isoproterenol stimulated SGLT1 migration to luminal membrane, and reduced (50%) the BAL glucose concentration; whereas phlorizin increased the BAL glucose concentration (100%). These regulations were accompanied by parallel changes of in vitro MRSA and P. aeruginosa proliferation in BAL (r = 0.9651 and r = 0.9613, respectively, Pearson correlation). The same regulations were observed in in vivo P. aeruginosa proliferation. In summary, the results indicate a relationship among SGLT1 activity, ASL glucose concentration and pulmonary bacterial proliferation. Besides, the study highlights that, in situations of pulmonary infection risk, such as in diabetic subjects, increased SGLT1 activity may prevent bacterial proliferation whereas decreased SGLT1 activity can exacerbate it.

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 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.

    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.

  3. Pulmonary disposition of 67Ga in humans: concise communication

    International Nuclear Information System (INIS)

    Pulmonary 67Ga imaging for inflammatory and neoplastic diseases has become an important diagnostic tool in respiratory medicine. However, the extent to which 67Ga is delivered to normal lungs has not been fully evaluated. Accordingly, researchers measured the disposition of 67Ga using scintiscanning, bronchoalveolar lavage (BAL), and blood analysis in healthy subjects. Following an intravenous dose of 6 mCi 67Ga citrate, the gallium scan showed no pulmonary uptake at 48 hr. In all subjects, radioactivity was detected in both blood and recovered BAL fluid at 72 hr, being predominantly in the cellular component of the BAL washings. Researchers conclude that despite negative pulmonary imaging, 67Ga accumulates in the cells that line the alveolar acini of normal nonsmoking individuals

    Full Text Available Bronchoalveolar lavage (BAL is a procedure that retrieves cells and other elements from the lungs for evaluation, which helps in the diagnosis of pulmonary diseases. The aim of this study was to perform this procedure for cellular analysis of BAL fluid alterations during experimental infection with Aelurostrongylus abstrusus in cats. 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.

    Mediator release was examined from superficially lying cells in the airway epithelium obtained by bronchoalveolar lavage (BAL) in 13 non-atopic individuals. The BAL-cells were incubated (20 min, 37 degrees C) with Staphylococcus (Staph.) aureus or with human influenza A virus Staph. aureus...... was found to release histamine from cells from 7 of the 13 individuals and influenza A virus in 3 of 5 persons. Furthermore, Staph, aureus stimulated the BAL-cells to release leukotriene B4 in 7 of 11 subjects, whereas no release was found by influenza A virus in 7 examined persons. When cells from 4...... persons were stimulated with Staph. aureus no release of leukotriene C4 was found. The mediator release caused by bacteria and virus might be of importance for the exacerbation of bronchial asthma in upper respiratory tract infections, since histamine is assumed to increase the epithelial permeability...

  7. The clinical utility of bronchoalveolar lavage in diffuse parenchymal lung disease

    Directory of Open Access Journals (Sweden)

    2010-09-01

    Full Text Available Bronchoalveolar lavage (BAL has been used in diagnostic and prognostic evaluation in diffuse parenchymal lung disease for three decades and has a central role in the diagnosis of a number of rare disorders and in excluding opportunistic infection in treated patients. It also has an important place in the personal diagnostic algorithms of many experienced clinicians in the diagnosis of the more prevalent disorders, including sarcoidosis, hypersensitivity pneumonitis and idiopathic pulmonary fibrosis. This use of BAL is not well captured in the medical literature, as most published studies pre-date changes in disease classification and fail to integrate BAL data with other clinical and radiological information. Further studies to quantify the value added by bronchoalveolar lavage in routine practice are urgently required.

    . The tail moment in bronchoalveolar lavage (BAL) cells from BALB/c mice was determined by the comet assay as a measure of DNA strand breaks. Within the first 200 min after exposure, the BAL cells from the mice exposed to I or 2 ppm ozone had 1.6- and 2.6-fold greater tail moments than unexposed mice....... Also at I ppm ozone, the IL-6 mRNA was induced. The large induction of IL-6 mRNA in the lung took place after DNA strand breaks were induced in BAL. This does not support the notion that inflammatory reactions are the cause of DNA damage. To determine whether these exposures were mutagenic, Muta...

In this study, we investigated inflammatory and acute phase response in addition to genotoxic effects occurring following exposure to nanoparticulate carbon black (NPCB) at even lower doses. C57BL/6JBomTac mice were examined 1, 3, and 28 days after a single...... instillation of 0.67, 2, 6, and 162 mu g Printex 90 NPCB and vehicle. Cellular composition and protein concentration was evaluated in BAL fluid as markers of inflammatory response and cell damage. DNA strand breaks in BAL cells, lung, and liver tissue were assessed using the alkaline comet assay. The pulmonary...... acute phase response was analyzed by Saa3 mRNA real-time quantitative PCR. Instillation of the low doses of NPCB induced a slight neutrophil influx one day after exposure. Pulmonary exposure to small doses of NPCB caused an increase in DNA strand breaks in BAL cells and lung tissue measured using the...

    1974-01-01

    A hybrid programming language ANIBAL has been developed for use in an open-shop computing centre with an EAI-680 analog computer, a PDP8/I digital computer, and a FFP-12 floating point processor. An 8K core memory and 812k disk memory is included. The new language consists of standard FORTRAN IV...... and special hybrid computer commands. ANIBAL consists of a general-purpose analog interface subroutine ANI and the macro processor 8BAL (DECUS NO 8-497A.1). When a source program with FORTRAN and 8BAL statements is processed, the FORTRAN statements are transferred unchanged, while the 8BAL code is translated...... essentially to ANI sub-routine calls, which are defined in a macro library. The resulting code is translated by the standard FORTRAN compiler. The language is very flexible as the instructions can be changed and commands can be added to or excluded from the library ....

  13. THE LONG-TERM X-RAY VARIABILITY OF BROAD ABSORPTION LINE QUASARS

    International Nuclear Information System (INIS)

    We analyze the long-term (rest-frame 3-30 yr) X-ray variability of 11 broad absorption line (BAL) quasars, mainly to constrain the variation properties of the X-ray absorbing shielding gas that is thought to play a critical role in BAL wind launching. Our BAL quasar sample has coverage with multiple X-ray observatories including Chandra, XMM-Newton, BeppoSAX, ASCA, ROSAT, and Einstein; 3-11 observations are available for each source. For seven of the eleven sources we have obtained and analyzed new Chandra observations suitable for searching for any strong X-ray variability. We find highly significant X-ray variability in three sources (PG 1001+054, PG 1004+130, and PG 2112+059). The maximum observed amplitude of the 2-8 keV variability is a factor of 3.8 ± 1.3, 1.5 ± 0.2, and 9.9 ± 2.3 for PG 1001+054, PG 1004+130, and PG 2112+059, respectively, and these sources show detectable variability on rest-frame timescales down to 5.8, 1.4, and 0.5 yr. For PG 1004+130 and PG 2112+059 we also find significant X-ray spectral variability associated with the flux variability. Considering our sample as a whole, we do not find that BAL quasars exhibit exceptional long-term X-ray variability when compared to the quasar population in general. We do not find evidence for common strong changes in the shielding gas owing to physical rearrangement or accretion-disk rotation, although some changes are found; this has implications for modeling observed ultraviolet BAL variability. Finally, we report for the first time an X-ray detection of the highly polarized and well-studied BAL quasar IRAS 14026+4341 in its new Chandra observation.

    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.

    Full Text Available Peripheral blood interferon-gamma release assays (IGRAs have sub-optimal sensitivity and specificity for diagnosis of active pulmonary tuberculosis (TB. However, assessment of local immune responses has been reported to improve the accuracy of TB diagnosis.We enrolled HIV-infected adults with cough ≥2 weeks' duration admitted to Mulago Hospital in Kampala, Uganda and referred for bronchoscopy following two negative sputum acid-fast bacillus smears. We performed an ELISPOT-based IGRA (T-SPOT.TB®, Oxford Immunotec, Oxford, UK using peripheral blood and bronchoalveolar lavage (BAL fluid mononuclear cells, and determined the accuracy of IGRAs using mycobacterial culture results as a reference standard.94 HIV-infected patients with paired peripheral blood and BAL IGRA results were included. The study population was young (median age 34 years [IQR 28-40 years] and had advanced HIV/AIDS (median CD4+ T-lymphocyte count 60 cells/µl [IQR 22-200 cells/µl]. The proportion of indeterminate IGRA results was higher in BAL fluid than in peripheral blood specimens (34% vs. 14%, difference 20%, 95% CI 7-33%, p = 0.002. BAL IGRA had moderate sensitivity (73%, 95% CI 50-89% but poor specificity (48%, 95% CI 32-64% for TB diagnosis. Sensitivity was similar (75%, 95% CI 57-89% and specificity was higher (78%, 95% CI 63-88% when IGRA was performed on peripheral blood.BAL IGRA performed poorly for the diagnosis of smear-negative TB in a high HIV/TB burden setting. Further studies are needed to examine reasons for the large proportion of indeterminate results and low specificity of BAL IGRA for active TB in high HIV/TB burden settings.

    Full Text Available Abstract Background Idiopathic pulmonary fibrosis (IPF is a chronically progressive interstitial lung disease of unknown etiology. Previously, we have demonstrated the selective upregulation of the macrophage-derived chemokine CCL22 and the thymus activation-regulated chemokine CCL17 among chemokines, in a rat model of radiation pneumonitis/pulmonary fibrosis and preliminarily observed an increase in bronchoalveolar (BAL fluid CCL22 levels of IPF patients. Methods We examined the expression of CCR4, a specific receptor for CCL22 and CCL17, in bronchoalveolar lavage (BAL fluid cells, as well as the levels of CCL22 and CCL17, to elucidate their pathophysiological roles in pulmonary fibrosis. We also studied their immunohistochemical localization. Results BAL fluid CCL22 and CCL17 levels were significantly higher in patients with IPF than those with collagen vascular diseases and healthy volunteers, and there was a significant correlation between the levels of CCL22 and CCL17 in patients with IPF. CCL22 levels in the BAL fluid did not correlate with the total cell numbers, alveolar lymphocytes, or macrophages in BAL fluid. However, the CCL22 levels significantly correlated with the numbers of CCR4-expressing alveolar macrophages. By immunohistochemical and immunofluorescence analysis, localization of CCL22 and CCR4 to CD68-positive alveolar macrophages as well as that of CCL17 to hyperplastic epithelial cells were shown. Clinically, CCL22 BAL fluid levels inversely correlated with DLco/VA values in IPF patients. Conclusion We speculated that locally overexpressed CCL22 may induce lung dysfunction through recruitment and activation of CCR4-positive alveolar macrophages.

    Background FTA® cards (Fast Technology for Analysis of Nucleic Acids) are an alternative DNA extraction method in bronchoalveolar lavage (BAL) samples for Pneumocystis jirovecii molecular analyses. The goal was to evaluate the usefulness of FTA® cards to detect P. jirovecii-DNA by PCR in BAL samples compared to silica adsorption chromatography (SAC). Methods This study used 134 BAL samples from immunocompromised patients previously studied to establish microbiological aetiology of pneumonia, among them 15 cases of Pneumocystis pneumonia (PCP) documented by staining and 119 with other alternative diagnoses. The FTA® system and SAC were used for DNA extraction and then amplified by nested PCR to detect P. jirovecii. Performance and concordance of the two DNA extraction methods compared to P. jirovecii microscopy were calculated. The influence of the macroscopic characteristics, transportation of samples and the duration of the FTA® card storage (1, 7, 10 or 12 months) were also evaluated. Results Among 134 BAL samples, 56% were positive for P. jirovecii-DNA by SAC and 27% by FTA®. All 15 diagnosed by microscopy were detected by FTA® and SAC. Specificity of the FTA® system and SAC were 82.4% and 49.6%, respectively. Compared to SAC, positivity by FTA® decreased with the presence of blood in BAL (62% vs 13.5%). The agreement between samples at 7, 10 and 12 months was 92.5% for FTA®. Positive cases by FTA® remained the same after shipment by mail. Conclusions Results suggest that FTA® is a practical, safe and economical method to preserve P. jirovecii-DNA in BAL samples for molecular studies. PMID:26950684

    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.

    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.

    Pulmonary toxicity studies often use bronchoalveolar lavage (BAL) to investigate potential adverse lung responses to a particulate exposure. The BAL cellular fraction is counted, using automated (i.e. Coulter Counter®), flow cytometry or manual (i.e. hemocytometer) methods, to determine inflammatory cell influx. The goal of the study was to compare the different counting methods to determine which is optimal for examining BAL cell influx after exposure by inhalation or intratracheal instillation (ITI) to different particles with varying inherent pulmonary toxicities in both rat and mouse models. General findings indicate that total BAL cell counts using the automated and manual methods tended to agree after inhalation or ITI exposure to particle samples that are relatively nontoxic or at later time points after exposure to a pneumotoxic particle when the response resolves. However, when the initial lung inflammation and cytotoxicity was high after exposure to a pneumotoxic particle, significant differences were observed when comparing cell counts from the automated, flow cytometry and manual methods. When using total BAL cell count for differential calculations from the automated method, depending on the cell diameter size range cutoff, the data suggest that the number of lung polymorphonuclear leukocytes (PMN) varies. Importantly, the automated counts, regardless of the size cutoff, still indicated a greater number of total lung PMN when compared with the manual method, which agreed more closely with flow cytometry. The results suggest that either the manual method or flow cytometry would be better suited for BAL studies where cytotoxicity is an unknown variable. PMID:27251196

    International Nuclear Information System (INIS)

    Formation of quaternary oxides CaABB'O7 of the composition at A=Ti, Zr, Hf, Sn, B=Al, Ga, Cr, Fe, In, B'=Sb, Nb, Ta is studied. Crystal zirconolite structure has been found in twelve samples containing gallium, ferrum (3) titanium, zirconium, hafnium, niobium, tantalum and antimony (5). In the cases, when A=Sn, B=Al quaternary oxides of the above composition are not formed. It is shown that zirconolite structure stability depends not only on cation dimensions but also on their electron structure

  4. A case of pulmonary alveolar microlithiasis

    International Nuclear Information System (INIS)

    A case of pulmonary alveolar microlithiasis is reported. A 33-year-old male visited our clinic because of cough and sore throat. The chest X-ray showed granular micronodulation diffusely disseminated throughout the lung fields. On the eighth day since admission, cough and sore throat disappeared. Pulmonary alveolar microlithiasis was confirmed by transbronchial lung biopsy. Bronchoalveolar lavage (BAL) was performed, and the differential cell count of the BAL fluid showed 74.3 % eosinophilia. Furthermore, 67Ga-citrate scintigraphy revealed diffuse uptake throughout the lung fields. Whether these findings are common in pulmonary alveolar microlithiasis or not is considered to be an unanswered problem. (author)

    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.

    Full Text Available We present the results of bronchoalveolar lavage (BAL performed in three patients with severe influenza A/H1N1 pneumonia complicated by acute respiratory distress syndrome (ARDS. Light microscopy analysis of BAL cytocentrifugates showed the presence of characteristic large, mononuclear, plasmoblastic/plasmocytoid-like cells never described before. Via transmission electron microscopy, these cells were classified as atypical type II pneumocytes and some of them showed cytoplasmic vesicles and inclusions. We concluded that plasmoblastic/plasmocytoid-like type II pneumocytes might represent a morphologic marker of A/H1N1 influenza virus infection as well as reparative cellular activation after diffuse alveolar damage.

  12. Weak hard X-ray emission from broad absorption line quasars: evidence for intrinsic X-ray weakness

    International Nuclear Information System (INIS)

    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 (Γeff ≈ 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.

    Pulmonary alveolar proteinosis (PAP) is a rare pulmonary disease. Diagnosis is established by bronchoalveolar lavage (BAL), which has macroscopic 'milky appearance', and in the presence of typical computed tomography, findings are diagnostic of PAP but, however, the feature of periodic acid-Schiff-positive eosinophilic proteinaceous fluid raises the confidence of the diagnosis. We report late-onset PAP in a 10-year-old girl who had acid fast bacilli on an initial BAL examination, but was subsequently diagnosed as PAP. PMID:26069841

    Soo Jung Um

    Full Text Available RATIONALE & AIM: Pulmonary surfactants are essential components of lung homeostasis. In chronic obstructive pulmonary disease (COPD, surfactant expression decreases in lungs whereas, there is a paradoxical increase in protein expression in plasma. The latter has been associated with poor health outcomes in COPD. The purpose of this study was to determine the relationship of surfactants and other pneumoproteins in bronchoalveolar lavage (BAL fluid and plasma to airflow limitation and the effects of budesonide/formoterol on this relationship. METHODS: We recruited (clinical trials.gov identifier: NCT00569712 7 smokers without COPD and 30 ex and current smokers with COPD who were free of exacerbations for at least 4 weeks. All subjects were treated with budesonide/formoterol 400/12 µg twice a day for 4 weeks. BAL fluid and plasma samples were obtained at baseline and the end of the 4 weeks. We measured lung-predominant pneumoproteins: pro-Surfactant Protein-B (pro-SFTPB, Surfactant Protein-D (SP-D, Club Cell Secretory Protein-16 (CCSP-16 and Pulmonary and Activation-Regulated Chemokine (PARC/CCL-18 in BAL fluid and plasma. RESULTS: BAL Pro-SFTPB concentrations had the strongest relationship with airflow limitation as measured by FEV1/FVC (Spearman rho=0.509; p=0.001 and FEV1% of predicted (Spearman rho= 0.362; p=0.028. Plasma CCSP-16 concentrations were also significantly related to airflow limitation (Spearman rho=0.362; p=0.028 for FEV1% of predicted. The other biomarkers in BAL fluid or plasma were not significantly associated with airflow limitation. In COPD subjects, budesonide/formoterol significantly increased the BAL concentrations of pro-SFTPB by a median of 62.46 ng/ml (p=0.022 or 48.7% from baseline median value. CONCLUSION: Increased severity of COPD is associated with reduced Pro-SFTPB levels in BAL fluid. Short-term treatment with budesonide/formoterol increases these levels in BAL fluid. Long term studies will be needed to determine

    La esclerosis concéntrica de Baló es una variante infrecuente de enfermedad desmielinizante relacionada con la esclerosis múltiple, inicialmente considerada de progresión fatal. En estudios recientes se reportan variantes no fatales de esclerosis concéntrica de Baló en los que se enfatiza la importancia del diagnóstico por medio de la imagen por resonancia magnética, utilizando además la espectroscopia y las secuencias de difusión y perfusión. En los últimos años se ha logrado reproducir la i...

  12. Development of high-strength aluminum alloys for basket in transport and storage cask for high burn-up spent fuel

    International Nuclear Information System (INIS)

    Mitsubishi Heavy Industries, Ltd. (MHI) has developed high-strength borated aluminum alloys (high-strength B-Al alloys), suitable for application to baskets in transport and storage casks for high burn-up spent fuels. Aluminum is a suitable base material for the baskets due to its low density and high thermal conductivity. The aluminum basket would reduce weight of the cask, and effectively release heat generated by spent fuels. MHI had already developed borated aluminum alloys (high-toughness B-Al alloy), and registered them as ASME Code Case ''N-673''. However, there has been a strong demand for basket materials with higher strength in the case of MSF (Mitsubishi Spent Fuel) casks for high-burn up spent fuels, since the basket is required to stand up to higher stress at higher temperature. The high-strength basket material enables the design of a compact cask under a limitation of total size and weight. MHI has developed novel high-strength B-Al alloys which meet these requirements, based on a new manufacturing process. The outline of mechanical and metallurgical characteristics of the high-strength B-Al alloys is described in this paper

    This paper proposes a framework for reading mathematics texts as narratives. Building from a narrative framework of Meike Bal, a reader's experience with the mathematical content as it unfolds in the text (the "mathematical story") is distinguished from his or her logical reconstruction of the content beyond the text (the…

    The objective of this study was to investigate the mechanisms of physiological control of the craniomandibular system during force-controlled biting: in intercuspation, restricted by predetermined anatomic-geometrical conditions [i.e. biting in intercuspation (BIC)]; and on a hydrostatic system [i.e. auto-balanced static equilibrium of the mandible (BAL)], in which the mandible is balanced under unrestricted occlusal conditions. For 20 healthy subjects, the spatial positions of the condyles, the lower molars, and the incisal point were measured, and the electromyographic (EMG) activity of the musculus masseter and musculus temporalis anterior were recorded bilaterally, during force-controlled biting (50, 75, 100 N) on a hydrostatic device. The results were compared with those obtained during BIC. During BAL, the neuromuscular system stabilizes one condyle, so it behaves as a virtual fulcrum, and all available biomechanical degrees of freedom of the opposite side are used to achieve a bilaterally equal vertical distance between the upper and lower dental arches. The variability of the positions of the molars was significantly smaller than for the condyles. The EMG co-contraction ratios calculated for homonymous muscle regions revealed significant differences between BIC and BAL, specifically, greater symmetry during BAL with substantial asymmetry of approximately 25% remaining. In conclusion, the results revealed precise neuromuscular control of the position of the lower dental arch; this information might form the basis for interference-free tracking of the mandible in intercuspation under different conditions.

  20. Immune complexes, gallium lung scans, and bronchoalveolar lavage in idiopathic interstitial pneumonitis-fibrosis

    International Nuclear Information System (INIS)

    We obtained results of lung immune complexes (LIC), circulating immune complexes (CIC), 48-hour gallium lung scans (scans), bronchoalveolar lavage (BAL), and pulmonary function tests in 20 patients with idiopathic interstitial pneumonitis-fibrosis. Sixteen patients had predominantly interstitial (13 cases UIP) and/or intraalveolar (3 cases DIP) cellular disease (group 1). Prior to corticosteroid therapy in group 1, scans were positive in 75 percent, CIC were elevated in 86 percent, LIC were present in 64 percent, and BAL was abnormal in 90 percent. Duration of follow-up after treatment was 3.5 +/- 1.0 year. In group 1 after treatment with corticosteroids in 13 patients and corticosteroids and penicillamine (three patients) and plasmapheresis (one patient), only four patients remain stable or improved. After corticosteroid therapy, elevated CIC returned to normal values despite progressive patient deterioration. In three patients, lung immune complexes were still detected after circulating immune complexes had returned to normal after corticosteroid therapy. In group 2 were four patients with fibrotic disease; scans and CIC were uniformly negative, LIC were weakly present in only one patient, and BAL was abnormal in all. Despite corticosteroid therapy, all have died or deteriorated. These results suggest that positive gallium lung scans, BAL, circulating immune complexes, and to a lesser extent, lung immune complexes are associated with the cellular phase of interstitial pneumonia, but do not reliably identify a corticosteroid-responsive group
