    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...

    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...

  10. BAL QSOs and Extreme UFOs: The Eddington Connection

    Science.gov (United States)

    Zubovas, Kastytis; King, Andrew

    2013-05-01

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

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

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

  19. Constraining FeLoBAL outflows from absorption line variability

    McGraw, S M; Hamann, F W; Capellupo, D M; Gallagher, S C; Brandt, W N

    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.

Understanding physics behind BAL outflows might be a key to comprehend Galaxy Evolution as a whole.

    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.

(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...

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

    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'...

    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.

    2015-01-01

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

    2013-01-01

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

    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.

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

    Herbst, Hanna; Hamann, Fred; Villforth, Carolin; Caselli, Paola; Koekemoer, Anton M.; Veilleux, Sylvain

    2016-01-01

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

  19. Improvement of strength of B/Al composite by thermal-mechanical cycling

    2004-01-01

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

    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.

    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.

    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

    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.

    1983-01-01

    Literature data related to the thermally-induced strength degradation of B/Al composites were examined in the light of fracture theories based on reaction-controlled fiber weakening. Under the assumption of a parabolic time-dependent growth for the interfacial reaction product, a Griffith-type fracture model was found to yield simple equations whose predictions were in good agreement with data for boron fiber average strength and for B/Al axial fracture strain. The only variables in these equations were the time and temperature of the thermal exposure and an empirical factor related to fiber surface smoothness prior to composite consolidation. Such variables as fiber diameter and aluminum alloy composition were found to have little influence. The basic and practical implications of the fracture model equations are discussed.

    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.

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.

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

    CERN Document Server

    Faucher-Giguere, C -A; Murray, N

    2011-01-01

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

    2016-01-01

    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.

  16. Predicting the time-temperature dependent axial failure of B/Al composites

    Dicarlo, J. A.

    1980-01-01

    Theoretical and experimental studies are reviewed whose objective was to gain insight into and predict the effects of time, temperature, and stress on the axial failure modes of boron fibers and B/Al composites. Owing to the inelastic nature of boron fiber deformation, it proved possible to develop simple creep functions which can be used to describe accurately the creep and fracture stress of as-produced fibers. Analysis of damping and stress data for B/6061 Al composites indicates that fiber creep and the effects of creep of fiber fracture are measurably reduced by the composite fabrication process.

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

  18. 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.

    Full Text Available The article examines the administrative thinking of Aníbal Bascuñán Valdés, derived from the analysis of his book Elementos de Ciencia de la Administración Pública (1963. It highlights the value of Bascuñán to the intellectual history of the discipline, for being the first Hispanic American thinker who without hesitation supported the autonomous status of public administration and for conceiving it as scientific knowledge under an ontic approach, where his being is endowed with an identity and able to develop principles. It is concluded that the work of Bascuñán is one of the most developed within the discipline during the 1960s,above all because it considers public administration as an autonomous science and social science.

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

    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.

  6. 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

Se propone que la violencia material y simbólica ha sido el eje de todos los intercambios sociales de la modernidad, en la que se despliega un aparato de muerte y sufrimiento justificado en el progreso, la libertad y el mercado capitalista, bajo una lógica que evoca el sacrificio a los dioses y que sacraliza el orden liberal democrático.

Después de cinco siglos de coalición entre el poder político y la violencia, pareciera que la máquina de guerra caníbal no se ha saciado y reclama cada vez más sangre en nombre de la libertad y el progreso.

    Full Text Available Solar power and wind energy are used concurrently during specific periods, while at other times only the more efficient is used, and hybrid systems make this possible. When establishing a hybrid system, the extent to which these two energy sources support each other needs to be taken into account. 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.

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

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

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

    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.

    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

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

    Full Text Available The agricultural world is overloaded with chemical substances. Undesirable effects and the resistance of vermin opens a new way for biological control of pathogenic species of animals. Ips typographus (L. is overgrowth across Central Europe. Its natural habitat are forest communities, where chemical spraying is forbidden or restricted. The natural bioregulators of this cosmopolitan pest are entomopathogenic fungi of Hypocreales species. In this study, we focused on two types of entomopathogenic fungi – Beauveria bassiana (BALS. and Metarhizium anisopliae (METSCH.. They are suitable for biological control because they are attacking a wide range of pathogenic insects in agro-systems. Entomopathogenic fungi were isolated from soil samples and dead infected insects. The samples collected from different sites of the High Tatras. In our experiments, we followed infectivity and mortality of selected isolates of entomopathogenic fungi Beauveria bassiana (BALS. and Metarhizium anisopliae (METSCH.. The gDNA of isolates was used for identification and we put them to the analysis of specific DNA segments by amplified PCR method. Results of experiments show the high pathogenicity of entomopathogenic fungi strains. Beauveria bassiana (BALS. caused 99% mortality and Metarhizium anisopliae (METSCH. reached 97%. Infectivity followed by Beauveria bassiana (BALS. reached 92% and Metarhizium anisopliae (METSCH. 90%. For the purpose of limiting the numbers of populations of harmful pest is essential the ability of entomopathogenic fungi to infect, kill the host, and remain in a natural environment without disturbing the biota.

    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.

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

    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 {approx}1000 times greater in the core of the absorption profile than the value deduced from its apparent optical depth.

    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.

    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.

    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.

    Full Text Available This work aims to understand the organizational strategies used by the ballet company Grupo Corpo, based in Belo Horizonte, Minas Gerais, Brazil. 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.

    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

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

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

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.

    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.

    The study of high-redshift bright quasars is crucial to gather information about the history of galaxy assembly and evolution. Variability analyses can provide useful data on the physics of the quasar processes and their relation with the host galaxy. In this study, we aim at measuring the black hole mass of the bright lensed BAL QSO APM 08279+5255 at $z=3.911$ through reverberation mapping, and at updating and extending the monitoring of its C IV absorption line variability. Thanks to 138 R-band photometric data and 30 spectra available over 16 years of observations, we perform the first reverberation mapping of the Si IV and C IV emission lines for a high-luminosity quasar at high redshift.

    We 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...

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

  2. Feeding Habits of Introduced Black Rats, Rattus rattus, in Nesting Colonies of Galapagos Petrel on San Cristóbal Island, Galapagos.

    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

  3. Linking SO2 emission rates and seismicity by continuous wavelet transform: implications for volcanic surveillance at San Cristóbal volcano, Nicaragua

    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.

    2008-12-01

    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.

    Full Text Available En el presente artículo analizamos cómo fue valorado entre sus contemporáneos Voces usadas en Chile (1900, del abogado y lingüista aficionado chileno Aníbal Echeverría y Reyes, según muestra un corpus de seis textos críticos de esta obra fechados entre 1899 y 1905. Algunos de estos textos fueron publicados en la prensa chilena y estadounidense, y el resto en forma de libro. Entre sus autores se hallan Rodolfo Lenz, Miguel Luis Amunátegui Reyes y Fidelis del Solar, quienes desempeñaron papeles importantes en el desarrollo de la lingüística en Chile. Concluimos que la recepción de la obra de Echeverría fue mayormente negativa porque los comentaristas la interpretaron como una obra prescriptiva que adolecía de defectos fundamentales para cumplir con su propósito normativo, interpretación congruente con el periodo de la lexicografía y la lingüística chilena en que se enmarca, llamado precientífico por Matus (1994 y caracterizado por un marcado interés normativista. Entre las críticas más abundantes sobresale el desacuerdo sobre el tratamiento normativo dado a ítems particulares, lo cual interpretamos en términos de una negociación de normas connatural a una comunidad lingüística que atraviesa un proceso de estandarización, como era el Chile hispanohablante de fines del siglo xrx.This paper analyzes how Voces usadas en Chile, a lexicographical work written by Chilean lawyer and amateur linguist Aníbal Echeverría y Reyes and published in 1900, was received by his contemporaries, as it can be seen in a corpus of six critical texts dated between 1899 and 1905. Some of these critical texts were published in Chilean and American press and the rest in book form. Among the authors of these texts are Rodolfo Lenz, Miguel Luis Amunátegui Reyes and Fidelis del Solar, all of which played a significant role in the development of linguistics in 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. Portanto, é importante determinar as exigências e as aproximações em matéria da silvicultura. A determinação das exigências da população urbana e rural no âmbito desse processo e a interpretação destinada aos assuntos das funções da floresta foram pesquisadas tendo como base a província turca de Bal kesir. As constatações resultantes do estudo na região demonstraram que as diferenças entre as exigências da população urbana e rural em matéria da silvicultura são a luta contra os incêndios florestais, a luta contra os delitos florestais, a integração de silvicultura-turismo, as atividades de reflorestamento e rejuvenescimento da floresta e a ampliação dos campos florestais.

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

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

  9. 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 La investigación se enfoca en revelar las princi- pales expresiones morfotectónicas del relieve, como contri- bución al estudio de la sismicidad moderada del territorio. El análisis morfoestructural se combina con resultados del análisis de estructuras a escala mesoscópica, para aportar elementos sobre la dirección preferencial de los esfuerzos tectónicos que determinaron el relieve contemporáneo. En total se describieron 44 afloramientos y se midieron 686 elementos estructurales (fracturas de extensión, de cizalla e híbridas, ejes y planos axiales de pliegues. Las interpre- taciones morfotectónicas y de índices geomorfológicos permitieron revelar la diferenciación morfoestructural en bloques, transversales a la falla sinestral Pinar, de potencial carácter sismogénico y, además, concluir sobre las direccio- nes principales y subordinadas de los esfuerzos tectónicos que generaron las mesoestructuras del substrato y las mor- foestructuras del relieve, parámetros significativos en la caracterización sismotectónica regional. Atención especial merece el “lomo de presión” generado sobre la traza de la falla Pinar, al norte de la localidad La Conchita, el que presenta una diferenciación en microbloques escalonados y desplazados horizontalmente, indicando una notable de- formación, cuya geodinámica sugiere una amenaza sísmica para los pueblos de San Cristóbal y Candelaria.

Methods The clinical manifestation, laboratory examination, neuroimaging characteristics, pathology and follow-up of 12 (2 outpatients and 10 inpatients) cases of BCS were analyzed retrospectively. Results The onset age of 12 patients (male 4, female 8) ranged from 8 to 54 years old (mean 36.8 years). Unconcerned and slowness response were common in the disease onset (7 cases).Other symptoms and signs such as hypophrenia ( 10 cases), limitation of limb or hand movement (8 cases),urinary and fecal incontinence (7 cases), hypo-myodynamia (7 cases), positive pyramidal sign (6 cases)were not rare in course of disease. Eight cases underwent the examination of cerebrospinal fluid myelin basic protein, which increased in 7 cases. Demyelinating change and perivascular inflammatory infiltration were shown in 6 brain biopsies. The involvements of multi-lesions were found in 11 cases. Four patients underwent CT scanning and all the cases showed with hypodense lesions and couldn' t be enhanced. On MRI, all cases appeared round or round-like in shape. Enhanced lesions showed ring-like or half-ting-like shape (8 cases) and concentric ring (3 cases). It's easy to be misdiagnosed as brain tumor (8 cases).Conclusions BCS is a kind of demyelinating disease of subacute or chronic onset accompanied with cognitive disorder being the most common initiating symptoms. It's prone to be misdiagnosed. Diagnosis depends on MRI and corticosteroid treatment is effective.

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.

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 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.

    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.

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

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.

    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 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).

    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...

Trichoderma sp., B. bassiana (isolado 634 e M. anisopliae (isolado E-9 foram inoculados em meio BDA, com intervalos de 0, 48, 120 e 168 horas entre a inoculação de Trichoderma sp. e dos entomopatógenos. Avaliou-se o crescimento radial das colônias nos períodos de 48 e 120 horas após a inoculação de Trichoderma sp., sendo que este afetou o desenvolvimento dos entomopatógenos quando inoculado simultaneamente ou após 48 horas. B. bassiana e M. anisopliae desenvolveram-se normalmente quando inoculados 168 horas antes de Trichoderma sp.. Também foi avaliado o efeito de um extrato de Trichoderma sp. sobre os entomopatógenos, com a adição de 0,1; 0,5; 1,0 e 5,0 ml de extrato/100,0 ml de meio, onde foram inoculados os entomopatógenos. Foram medidos os diâmetros de colônias e o número de conídios produzidos por B. bassiana e M. anisopliae na presença do extrato. A concentração de 5,0 ml de extrato/100,0 ml de meio alterou o crescimento e a conidiogênese de B. bassiana. O fungo M. anisopliae foi afetado a partir da adição de 1,0 ml de extrato/100,0 ml de meio.The objective of this work was to evaluate the effect of Trichoderma sp. on the development of Beauveria bassiana and Metarhizium anisopliae. The fungus Trichoderma sp. was inoculated on PDA culture medium, 0, 48, 120 and 168 hours after inoculation of the same plates with either B. bassiana (isolate 634 or M. anisopliae (isolate E-9. The radial growth of fungal colonies was measured 48 and 120 hours after Trichoderma sp. inoculation. Trichoderma sp. affected the development of both entomopathogenic fungi when inoculated simultaneously or 48 hours later. B. bassiana and M. anisopliae had normal development when inoculated 168 hours before Trichoderma sp. The effect of a toxic extract from Trichoderma sp. on the entomopathogenic fungi was also evaluated. Aliquots of 0.1, 0.5, 1.0 and 5.0 ml of extract were added to 100 ml of PDA medium, used to grow the entomopathogens. The radial growth of B. bassiana and M. anisopliae colonies grown in the presence of the extract were measured and the number of conidia produced per colony was counted. With 5% of extract in the medium, mycelial growth and conidiogenesis of B. bassiana decreased. M. anisopliae growth was affected by culture medium containing 1% or more of the extract.

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

Os meios líquidos testados foram: FC (farinha de crisálida, BD (batata+dextrose e FCBD (farinha de crisálida+batata+dextrose. Os períodos de avaliação da produção de biomassa foram: 24, 48, 72, 96, 120 e 144 hs. Para a produção pelo processo bífásico, diferentes quantidades dos meios líquidos (5, 10, 15 e 20 mL com diferentes períodos de incubação (24, 48 e 72 hs, foram adicionadas sobre arroz pré-cozido (200 g, avaliando-se a produção de conídios após 10 dias. Na produção de biomassa, o meio FCBD foi o mais produtivo durante todos os períodos avaliados. No processo bifásico, as maiores produções de conídios foram atingidas quando utilizou-se como inóculo do arroz, biomassa fúngica produzida nos meios FC e FCBD (2,7 x 1012 e 2,8 x 1012 conídios/g de arroz. As quantidades de 5, 15 e 20 mL de meio líquido, inoculadas sobre arroz, não diferiram estatisticamente. Os tempos de incubação de 24 e 48 hs, do fungo em meio líquido, proporcionaram maior conidiogênese do que em 72 hs. Os dados mostram a necessidade de fontes de carbono e nitrogênio na produção de biomassa em meio líquido e na conidiogênese em meio sólido. Também, é possível otimizar o processo bifásico, adicionando sobre o arroz (200 g 5 mL do meio líquido FCBD com 24 hs de incubação.

    Broad Absorption Lines indicate gas outflows with velocities from thousands km/s to about 0.2 the speed of light, which may be present in all quasars and may play a major role in the evolution of the host galaxy. The variability of absorption patterns can provide informations on changes of the density and velocity distributions of the absorbing gas and its ionization status. We collected 23 photometrical and spectro-photometrical observations at the 1.82m Telescope of the Asiago Observatory since 2003, plus other 5 spectra from the literature. We analysed the evolution in time of the equivalent width of the broad absorption feature and two narrow absorption systems, the correlation among them and with the R band magnitude. We performed a structure function analysis of the equivalent width variations. We present an unprecedented monitoring of a broad absorption line quasar based on 28 epochs in 14 years. The shape of broad absorption feature shows a relative stability, while its equivalent width slowly decline...

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

  18. 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

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

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

    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.

    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.

    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.

    The accretion of the interstellar medium onto central super-massive black holes is widely accepted as the source of the gigantic energy released by the active galactic nuclei. However, 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 that the absorbing medium is exposed to the radiation with ionization parameter U ≈ 10-1.8, and the density is n({{H}})≈ {10}9 {{cm}}-3. Thus the absorbing medium is located ˜4 pc away from the central engine. According to the similarity in the distance and physical conditions between the absorbing medium and the torus, we strongly propose the absorption line system as a candidate for the accretion inflow, which originates in the inner surface of the torus.

    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。

    2010-09-01

    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.

    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.

    Two cases of pulmonary alveolar proteinosis were treated with bronchoalveolar lavage (BAL) via a fibreoptic bronchoscope. Additional clinical improvement was seen when trypsin was added to the lavage fluid. Analysis of effluents in the BAL fluid showed marked reduction of protein constituents with clinical improvement after treatment with trypsin in the lavage. BAL with trypsin was well tolerated.

    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.

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.

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

    Science.gov (United States)

    Meyer, Keith C

    2014-04-01

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

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.

    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

    2008-11-01

    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.

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

    Giustini, M.

    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.

    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...

    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

    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.

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

    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

    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.

    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...

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

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

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

    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.

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

    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 ...

    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 ...

  13. 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.

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

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

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

    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.

    Full Text Available Ovalbumin (OVA-sensitized BALB/c mice were i.n. instilled with recombinant TNF-related apoptosis inducing ligand (TRAIL 24 hours before OVA challenge. The total number of leukocytes and the levels of the chemokine CXCL-1/KC significantly increased in the bronchoalveolar lavage (BAL fluids of allergic animals with respect to control littermates, but not in the BAL of mice i.n. pretreated with recombinant TRAIL before OVA challenge. In particular, TRAIL pretreatment significantly reduced the BAL percentage of both eosinophils and neutrophils. On the other hand, when TRAIL was administrated simultaneously to OVA challenge its effect on BAL infiltration was attenuated. Overall, the results show that the i.n. pretreatment with TRAIL down-modulated allergic airway inflammation.

    2011-08-01

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

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

    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.

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

    LENUS (Irish Health Repository)

    McNally, P

    2012-02-01

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

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

    Directory of Open Access Journals (Sweden)

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

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

    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.

  7. Topical efficacy of dimercapto-chelating agents against lewisite-induced skin lesions in SKH-1 hairless mice

    International Nuclear Information System (INIS)

    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

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

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

    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.

    Although bronchoalveolar lavage (BAL) is often used in the diagnosis of interstitial lung diseases (ILDs), its importance in investigating, in particular, idiopathic pulmonary fibrosis (IPF) is controversial. The cell distributions in the BAL are taken into account in the clinical routine, non-cellular characteristics of the BAL play no role.Using mathematical modeling of data, the present work investigated the extent to which BAL features enable drawing conclusions about the underlying ILK or help exclude IPF. Included in the calculation are cellular findings of the BAL, in addition the protein and albumin content of the BAL, the nicotine history (pack years), and spirometry (FEV1, IVC).Using linear discriminant analysis and creating classification trees, the relevance of the characteristics of 806 patients with ILK was examined (183 IPF, 191 cryptogenic organizing pneumonia, 147 lung involvement in autoimmune disease, 97 respiratory bronchiolitis interstitial lung disease, 118 extrinsic allergic alveolitis, 41 lymphocytic interstitial pneumonia (LIP), 23 non-specific interstitial pneumonia (NSIP), 88 controls).There was a close positive relationship between protein levels and lymphocytes in the group as a whole. No such correlations were seen in IPF and NSIP. Albumin was closely correlated with the protein content in all groups.The lymphocytes are best suited to distinguish between different ILDs. Yet, a reliable calculation of the ILD is not possible on the basis of the investigated factors, the classification error ranged from 23.5 % (IPF) to 100 % (LIP, NSIP).Constellations that likely (> 99 %) speak against an IPF are lymphocytosis > 34 % or protein content > 347 mg/l. The same applies to the constellation: lymphocytes > 25 % together with protein > 250 mg/l.In ILD, BAL findings can narrow the diagnosis, but they are seldom diagnostic. BAL can make an important contribution to excluding of IPF. PMID:27218212

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

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

    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.

    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.

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

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

    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.

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

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

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

    2008-01-01

    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...

    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.

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

    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).

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

    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

    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.

    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.

    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 ....

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

    Directory of Open Access Journals (Sweden)

    A.U. Wells

    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.

  4. 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

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

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

    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.

    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.

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

    Full Text Available 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.

    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

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

    meso-Dimercaptosuccinic acid (DMSA), 2,3-dimercapto-1-propanesulfonic acid, Na salt (DMPS), and N-(2,3- dimercaptopropyl )- phthalamidic acid (DMPA) are water soluble analogs of 2,3-dimercapto-1-propanol (BAL). The relative effectiveness or therapeutic index of these dimercapto compounds in protecting mice from the lethal effects of an LD99 of sodium arsenite is DMSA greater than DMPS greater than DMPA greater than BAL in the magnitude of 42:14:4:1, respectively. DMPS, DMPA, or DMSA will mobilize tissue arsenic. BAL, however, increases the arsenic content of the brain of rabbits injected with sodium arsenite. These results raise the question as to the appropriateness of BAL as the treatment for systemic arsenic poisoning. Either DMSA or DMPS, when given sc or po, will protect rabbits against the lethal systemic effects of subcutaneously administered Lewisite . DMPS and DMSA have promise as prophylactics for the prevention of the vesicant action of Lewisite . The sodium arsenite inhibition of the pyruvate dehydrogenase (PDH) complex can be prevented and reversed in vitro or in vivo by DMPS, DMSA, DMPA, or BAL. Of them all, DMPS is most potent and BAL appears to be the least potent. The usefulness of all these dimercapto compounds would be enhanced by a careful study of their metabolism and biotransformation. These dimercapto compounds are in a great many respects orphan drugs. At this stage of their development, it is very difficult for the clinician to obtain funds to study them clinically even though they appear to be useful for treatment of poisoning by any one of the heavy metals.

  19. 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)

    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

  6. Budesonide/formoterol enhances the expression of pro Surfactant Protein-B in lungs of COPD patients.

    Directory of Open Access Journals (Sweden)

    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

    lavage (BAL) fluid from smokers, but intracellularly located PAD cannot be responsible for citrullination of extracellular self-antigens. We aimed to establish a link between smoking and extracellular PAD2 in the lungs. METHODS: BAL fluid samples were obtained from 13 smokers and 11 nonsmoking controls...... fluids from smokers as compared to non-smokers (p=0.018). The PAD2 content correlated with the overall CRP levels (p=0.009) and cell count (p=0.016). CONCLUSIONS: This first demonstration of increased levels of extracellular PAD2 in the lungs of smokers supports the hypothesis that smoking promotes...

    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.

    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.

    AIM: To determine the expressions of cysteinyl leukotriene receptors, CysLT1 and CysLT2, in airway eosinophilic inflammation of OVA-induced asthmatic mice and the modulation by montelukast, a CysLT1 receptor antagonist.METHODS: Asthma model was induced by chronic exposure to ovalbumin (OVA) in C57BL/6 mice. The eosinophils in bronchoalveolar lavage (BAL) fluid and lung tissues were counted, IL-5 level in BAL fluid was measured,and CysLT1 and CysLT2 receptor mRNA expressions were detected by semi-quantitative RT-PCR. RESULTS:Montelukast (6 mg/kg, once per day for 20 d) significantly suppressed the increased eosinophils in BAL fluid and lung tissue, and increased IL-5 level in BAL fluid in OVA challenged mice. OVA challenge increased CysLT1 but decreased CysLT2 receptor mRNA expression. Montelukast inhibited the increased CysLT1 but not the reduced CysLT2 expression after OVA challenge. CONCLUSION: CysLT receptors are modulated immunologically, and montelukast inhibits up-regulation of CysLT1 receptor and airway eosinophilic inflammation in asthmatic mice.

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

  8. CT scan patterns of pulmonary alveolar proteinosis in children

    International Nuclear Information System (INIS)

    Background. To study computed tomographic (CT) findings in children with pulmonary alveolar proteinosis (PAP) more extensively. Objective. To describe the CT features at the time of diagnosis and after therapeutic broncho-alveolar lavage (BAL). Materials and methods. We retrospectively reviewed the CT scans of five children (aged 3 months to 4 years) examined because of incidental bronchitis (n = 1), disease in a sibling (n = 1) and relapsing fever, cough and dyspnoea (n = 3). Each patient had an initial CT scan. Two asymptomatic cases were not treated but were followed up by plain chest films. The other three had BAL and follow-up CT. Results. Initial CT in all cases showed a diffuse reticulomicronodular pattern associated in three cases with posterior bilateral alveolar infiltrates. CT in the two asymptomatic patients remained unchanged or slightly improved without BAL. After BAL, a variable decrease of lung infiltrates was observed. Conclusions. Correlation between the extent of alveolar consolidation and severity of disease was found. Anatomical and pathological considerations allow us to consider that the classical reticulomicronodular pattern is not due to an interstitial infiltration but to alveoli filled with the abnormal material characteristic of PAP.

    Free cell state of bronchial-alveolar liquid (BAL) of animal - descendants F1 from rats, containing in Chernobyl NPP zone (soil activity on 137Cs is 23 kBq/kg, gamma-background is 0,5 mSv/hours) were investigated. Term of descendant appearance is 7-10 days after returning animal from a zone. In 1 month after birth animal began to receive the contaminated forage (190-756 Bq/kg). In experiment on researching of descendants of 1-st breed from rats kept in the zone and reared the forage contaminated by radionuclides decreasing of animal weight at the age of 6 months on 14 % in comparison with the control was revealed. Besides in this period of observation for experimental animals the decrease of general cytosis BAL almost in 2 times was detected. On the background of decreasing general cytosis and number of AM the tendency to increase of the contents of neutrophils was marked. In the age of 9 mon. the tendency to decreasing of general cytosis was detected. At the age of 12 mon. increase of free cell quantity, tendency to increasing of AM number in BAL is marked. Quantity of remaining cell of BAL was at a level of monitoring values. (Authors)

    We describe the motivation and features of a multiwavelength spectroscopic campaign on broad absorption line (BAL) QSO PG~0946+301. The main goal of this project is to determine the ionization equilibrium and abundances (IEA) in BAL outflows. Previous studies of IEA in BALQSOs were based on the assumption that the BALs are not saturated so that the column densities inferred from the apparent optical depths are realistic. This critical assumption is at odds with several recent observations and with analysis of existing data which indicate that the absorption troughs are heavily saturated even when they are not black. In addition, X-ray observations, which are important for constraining the ionizing continuum, were not available for those objects that had UV spectral data. Quantifying the level of saturation in the BALs necessitates UV spectroscopy with much higher S/N and broader spectral coverage than currently exist. After taking into account the capabilities of available observatories, our best hope for a s...

    Partial bowel obstruction is a serious complication of ascariasis infestation generally treated with mineral oil. This prospective study aimed to evaluate the efficacy of multiple bronchoalveolar lavages (BAL) as a therapeutic strategy for reducing lung inflammation of lipoid pneumonia associated with ascariasis. The study included five children (mean age 25 months) with partial small-bowel obstruction by Ascaris lumbricoides, who underwent diagnostic bronchoalveolar lavage for assessment of refractory pneumonia. Routine biochemical, microbiological and cytological analysis were carried out in the BAL. Protein, lactate dehydrogenase and tumor necrosis factor-alpha (TNF-α) cytokine levels were determined in the serum before and after treatment. At admission, children consistently had respiratory symptoms, altered hematological function, increased immunoglobulin E serum level and peripheral blood eosinophilia. Chest tomography showed consolidation with air bronchogram (4/4), ground-glass infiltration (3/4) and decreased attenuation in the consolidation areas (2/4). Presence of marked pleocytosis with Sudan positive foamy alveolar macrophages, high protein and lactate dehydrogenase levels in the BAL indicated presence of mixed alveolitis. One child with extensive consolidation and air bronchogram in both lungs died before treatment. Multiple bronchoalveolar lavages efficiently removed alveolar oil deposits, restored BAL cellularity, improved clinical symptoms, radiological parameters and further reduced inflammatory reaction evidenced by marked decrease of the inflammatory cytokine, TNF-α. This study presents a therapeutic strategy for management of lung complications caused by mineral oil administration to treat intestinal bowel obstruction associated with ascariasis. PMID:20026557

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

  14. Weak Hard X-ray Emission from Two Broad Absorption Line Quasars Observed with NuSTAR: Compton-thick Absorption or Intrinsic X-ray Weakness?

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

    Background. To study computed tomographic (CT) findings in children with pulmonary alveolar proteinosis (PAP) more extensively. Objective. To describe the CT features at the time of diagnosis and after therapeutic broncho-alveolar lavage (BAL). Materials and methods. We retrospectively reviewed the CT scans of five children (aged 3 months to 4 years) examined because of incidental bronchitis (n = 1), disease in a sibling (n = 1) and relapsing fever, cough and dyspnoea (n = 3). Each patient had an initial CT scan. Two asymptomatic cases were not treated but were followed up by plain chest films. The other three had BAL and follow-up CT. Results. Initial CT in all cases showed a diffuse reticulomicronodular pattern associated in three cases with posterior bilateral alveolar infiltrates. CT in the two asymptomatic patients remained unchanged or slightly improved without BAL. After BAL, a variable decrease of lung infiltrates was observed. Conclusions. Correlation between the extent of alveolar consolidation and severity of disease was found. Anatomical and pathological considerations allow us to consider that the classical reticulomicronodular pattern is not due to an interstitial infiltration but to alveoli filled with the abnormal material characteristic of PAP.

  18. Constraining the shielded wind scenario in PG 2112+059

    The physical scenario describing the origin of quasar winds remains largely unsettled due to our failure to account for X-ray weak BAL quasars. We approach this problem by studying the relation between the inner part of the outflow which is likely to be shielding the X-ray emission and the UV winds characterized by broad absorption lines (BALs). In particular, we aim to probe the wind-shield connection in the highly X-ray variable BAL quasar PG 2112+059, which has exhibited periods of X-ray weakness and X-ray "normality" in the past. A set of two 20 ks Chandra observations and two contemporaneous {HST} observations, separated by at least eight months, combined with a nearly simultaneous archival Chandra-{HST} observation from 2002, afford us a unique opportunity to study the connection between the shield (which is thought to be responsible for the X-ray absorption) and the ionization state of the wind (observed as UV BAL features; e.g., C IV and O VI lines) over various timescales. In this review, which was based on a presentation in the XMM-Newton 2015 Science Workshop, we provide background relevant to our study and briefly analyze a recent Chandra observation of our new set of multiwavelength observations of PG 2112+059.
