Article Commentary: Virus Discovery Using Tick Cell Lines
Authors: Bell-Sakyi Lesley , Attoui Houssam
Published: September 2016

While ticks have been known to harbor and transmit pathogenic arboviruses for over 80 years, the application of high-throughput sequencing technologies has revealed that ticks also appear to harbor a diverse range of endogenous tick-only viruses belonging to many different families. Almost nothing is known about these viruses; indeed, it is unclear in most cases whether the identified viral sequences are derived from actual replication-competent viruses or from endogenous virus elements incorporated into the ticks' genomes. Tick cell lines play an important role in virus discovery and isolation through the identification of novel viruses chronically infecting such cell lines and by acting as host cells to aid in determining whether or not an entire replication-competent, infective virus is present in a sample. Here, we review recent progress in tick-borne virus discovery and comment on the actual and potential applications for tick cell lines in this emerging research area.
A Swedish Population-based Study of Adverse Birth Outcomes among Pregnant Women Treated with Buprenorphine or Methadone: Preliminary Findings
Authors: Wurst Keele E. , Zedler Barbara K. , Joyce Andrew R. , Sasinowski Maciek , Murrelle E. Lenn
Published: September 2016

Background

Untreated opioid dependence in pregnant women is associated with adverse birth outcomes. Buprenorphine and methadone are options for opioid agonist medication-assisted treatment during pregnancy.

Objective

The aim of this study was to describe adverse birth outcomes observed with buprenorphine or methadone treatment compared to the general population in Sweden.

Methods

Pregnant women and their corresponding births during 2005–2011 were identified in the Swedish Medical Birth Register. Data on stillbirth, neonatal/infant death, mode of delivery, gestational age at birth, Apgar score, growth outcomes, neonatal abstinence syndrome, and congenital malformations were examined. Frequencies were compared using two-sided Fisher's exact tests. Unadjusted estimates of birth outcomes for women treated with buprenorphine or methadone were compared to the registered general population.

Results

A total of 746,257 pregnancies among 538,178 unique women resulted in 746,485 live births. Among the 194 women treated with buprenorphine ( N = 176) or methadone ( N = 52), no stillbirths or neonatal/infant deaths occurred. Neonatal abstinence syndrome developed in 23.3% and 38.5% of infants born to mothers treated with buprenorphine and methadone, respectively. The frequency of the selected adverse birth outcomes assessed in women treated with buprenorphine as compared to the general population was not significantly different. However, a significantly higher frequency of preterm birth and congenital malformations was observed in women treated with methadone as compared to the general population. Compared with the general population, methadone-treated women were significantly older than buprenorphine-treated women, and both treatment groups began prenatal care later, were more likely to smoke cigarettes, and did not cohabitate with the baby's father.

Conclusions

An increased frequency of the selected adverse birth outcomes was not observed with buprenorphine treatment during pregnancy. Twofold increased frequency of preterm birth [2.21 (1.11, 4,41)] and congenital malformations [2.05 (1.08, 3.87)] was observed in the methadone group, which may be partly explained by older average maternal age and differences in other measured and unmeasured confounders.
Characterization of Positive Links and the s-invariant for Links
Authors: Abe Tetsuya , Tagami Keiji
Published: September 2016

We characterize positive links in terms of strong quasipositivity, homogeneity, and the
value of Rasmussen and Beliakova-Wehrli's s-invariant. We also study almost positive links, and in
particular, determine the s-invariants of almost positive links. This result suggests that all almost
positive links might be strongly quasipositive. On the other hand, it implies that almost positive
links are never homogeneous links

Global well-posedness and long-time asymptotics for the defocussing Davey–Stewartson II equation in $H^{1,1}(\mathbb C)$
Authors: Perry Peter A.
Published: September 2016

We use the

\bar {\partial}

-inverse scattering method to obtain global well-posedness and large-time asymptotics for the defocussing Davey–Stewartson II equation. We show that these global solutions are dispersive by computing their leading asymptotic behavior as

t \to \infty

in terms of an associated linear problem. These results appear to be sharp.
On anomalous Lieb–Robinson bounds for the Fibonacci XY chain
Authors: Damanik David , Lemm Marius , Lukic Milivoje , Yessen William
Published: September 2016

We rigorously prove a new kind of anomalous (or sub-ballistic) Lieb–Robinson bound for the isotropic XY chain with Fibonacci external magnetic field at arbitrary coupling. It is anomalous in that the usual exponential decay in

|x|-v|t|

is replaced by exponential decay in

|x|-v|t|^\alpha

with

0<\alpha<1

. In fact, we can characterize the values of

\alpha

for which such a bound holds as those exceeding

\alpha_u^+

, the upper transport exponent of the one-body Fibonacci Hamiltonian. Following the approach of [14], we relate Lieb–Robinson bounds to dynamical bounds for the one-body Hamiltonian corresponding to the XY chain via the Jordan–Wigner transformation; in our case the one-body Hamiltonian with Fibonacci potential. We can bound its dynamics by adapting techniques developed in [8, 9, 2, 3] to our purposes. To our knowledge, this is the first rigorous derivation of anomalous quantum many-body transport.

Along the way, we prove a new result about the one-body Fibonacci Hamiltonian: the upper transport exponent agrees with the time-averaged upper transport exponent, see Corollary 2.9. We also explain why our method does not extend to yield anomalous Lieb–Robinson bounds of power-law type for the random dimer model.
Quantum shuffles and quantum supergroups of basic type
Authors: Clark Sean , Hill David , Wang Weiqiang
Published: September 2016

We initiate the study of several distinguished bases for the positive half of a quantum supergroup

U_q

associated to a general super Cartan datum

(\mathrm{I}, (\cdot,\cdot))

of basic type inside a quantum shuffle superalgebra. The combinatorics of words for an arbitrary total ordering on

\mathrm{I}

is developed in connection with the root system associated to

\mathrm{I}

. The monomial, Lyndon, and PBW bases of

U_q

are constructed, and moreover, a direct proof of the orthogonality of the PBW basis is provided within the framework of quantum shuffles. Consequently, the canonical basis is constructed for

U_q

associated to the standard super Cartan datum of type

\mathfrak{gl}(n|1)

,

\mathfrak{osp}(1|2n)

, or

\mathfrak{osp}(2|2n)

or an arbitrary non-super Cartan datum. In the non-super case, this refines Leclerc's work and provides a new self-contained construction of canonical bases. The canonical bases of

U_q

, of its polynomial modules, as well as of Kac modules in the case of quantum

\mathfrak{gl}(2|1)

are explicitly worked out.
Two steps forward, one step back: Achievements and limitations of university-community partnerships in addressing neighbourhood socioeconomic disadvantage
Authors: Warr Deborah , Williams Richard
Published: September 2016

This article discusses a partnership initiative that involved a major Australian research university (University of Melbourne), a local government and a network of local community service organisations. The partnership projects aimed to promote public access to university infrastructure for poor and marginalised residents, enhance the local value of research and teaching activities, and create employment opportunities. The article draws on an evaluation of the partnership, which focused on four keynote projects. It found that the partnership appeared to achieve positive outcomes for residents but was limited by tensions associated with the university’s ambivalent commitment to the value of such partnerships. These tensions remained difficult to resolve because they signalled present contestation over the foundational values of contemporary public universities.Keywords: university-community partnerships, neoliberalism, neighbourhoods, community development
Fundamental researcher attributes: Reflections on ways to facilitate participation in Community Psychology doctoral dissertation research
Authors: Liboro Renato M , Travers Robb
Published: September 2016

As novice researchers, Community Psychology doctoral students encounter fresh challenges when they attempt to facilitate participation by members of the community in their dissertation projects. This article presents the merit in adopting fundamental researcher attributes, which have been described in published academic literature as personal characteristics that facilitate participation by members of the community in research studies. The value of these researcher attributes is exemplified in the discussion of one of the author’s experiences in the early stages of his dissertation research process. This article also presents new researcher attributes for facilitating participation by community members that the author recognised after critical reflection on his experiences during the same research process. Cultural humility, shared vulnerability, reflexivity, methodological flexibility, academic assiduity and creative resourcefulness are researcher attributes doctoral students should consider adopting and developing if they intend to facilitate participation by members of the community in their dissertation projects.Keywords: researcher attributes, graduate students, doctoral dissertation, participatory research, participation continuum
Unusual conversations: A reflection on the mechanics of internationally engaged public scholarship
Authors: Damiani Jonathan
Published: September 2016

This article analyses the civic engagement pathways of researchers from the Asia-Pacific and the United States in an effort to see how the principles of what American  scholars consider publicly engaged research and creative practice are being enacted in research sites across the globe. The purpose of this ongoing project is to focus on finding ways of connecting American scholars with a network of higher education and research institutions that hold a commitment and passion for social responsibility and civic engagement as it impacts education, research and service for community development overseas. The narrative includes the voices and perspectives of colleagues dedicated to engaged scholarship from across the new region in which I work (the Asia-Pacific), alongside the voices of some of Imagining America’s (IA) 2014 National Conference participants. These conversations serve as a critical reflection on the mechanics of doing public scholarship overseas and frame a new model of internationally engaged scholarship.Keywords: Internationally engaged public scholarship, unusual conversations
Supporting communities of practice: A reflection on the benefits and challenges facing communities of practice for research and engagement in nursing
Authors: De Waal Maretha , Khumisi Oumiki
Published: September 2016

Because of its potential self-sustainability, communities of practice may serve as useful practice-based knowledge sharing platforms for collaborative research and training, and thereby enhance development of human resources in the health sector. However, communities of practice are complex structures and need support from their host organisations and commitment from their members.  This article examines the diverse ways in which communities of nurse educators and practitioners who were part of a funded program in Tshwane District, South Africa evolved over a period of seven years. Adopting an ethnographic approach of reflexivity and learning, we compared and analysed the ways in which the communities of practice became sustainable over time. Our recommendations for institutional support of communities of practice in the health sector are based on the lessons we learned during the program that contributed to the configuration and reconfiguration of some of our communities of practice and the disengagement of others. We believe that our findings may have implications for replicability and sustainability of other communities of practice.Keywords: collaborative learning, collective knowledge, self-sustainability
Engaging youth in post-disaster research: Lessons learned from a creative methods approach
Authors: Peek Lori , Tobin-Gurley Jennifer , Cox Robin S , Scannell Leila , Fletcher Sarah , Heykoop Cheryl
Published: September 2016

Children and youth often demonstrate resilience and capacity in the face of disasters. Yet, they are typically not given the opportunities to engage in youth-driven research and lack access to official channels through which to contribute their perspectives to policy and practice during the recovery process. To begin to fill this void in research and action, this multi-site research project engaged youth from disaster-affected communities in Canada and the United States. This article presents a flexible youth-centric workshop methodology that uses participatory and arts-based methods to elicit and explore youth’s disaster and recovery experiences. The opportunities and challenges associated with initiating and maintaining partnerships, reciprocity and youth-adult power differentials using arts-based methods, and sustaining engagement in post-disaster settings, are discussed. Ultimately, this work contributes to further understanding of the methods being used to conduct research for, with, and about youth.Keywords: youth, disaster recovery, engagement, resilience, arts-based methods, participatory research
A multi-model approach to monitor emissions of CO2 and CO in an urban-industrial complex
Authors: Super Ingrid , Denier van der Gon Hugo A. C. , van der Molen Michiel K. , Sterk Hendrika A. M. , Hensen Arjan , Peters Wouter
Published: September 2016

Abstract. Monitoring urban-industrial emissions is often challenging, because observations are scarce and regional atmospheric transport models are too coarse to represent the high spatiotemporal variability in the resulting concentrations. In this paper we present a new combination of a Eulerian model (WRF-Chem with an urban parameterisation) and a Lagrangian transport-deposition model (OPS), demonstrating that a plume model strongly improves our ability to capture urban plume transport. This follows from a comparison to observed CO2 and CO mole fractions at four sites along a transect from an urban-industrial complex (Rotterdam, Netherlands) towards rural conditions. At the urban measurement site we find strong enhancements of up to 33.1 ppm CO2 and 84 ppb CO over the rural background concentrations. These signals are highly variable due to the presence of distinct source areas dominated by road traffic/residential heating emissions or industrial activities. This causes different emission signatures that are observed in the CO : CO2 ratios and can be well-reproduced with our framework, suggesting that top-down emission monitoring within this urban-industrial complex is feasible. Further downwind from the city, the urban plume is less frequently observed and its concentration becomes smaller and less variable, making these locations more suited for an integrated emission estimate over the whole study area. We find that WRF-Chem, although able to represent mesoscale patterns, lacks spatiotemporal detail to reproduce the timing, magnitude and variability of urban plumes at the regional background and urban sites. The implementation of the OPS plume model improves the simulation of the CO2 and CO enhancements. The bias for extreme CO2 pollution events is reduced with almost 80 % from 15.4 to 3.4 ppm, while the reproducible fraction of observed variability over 750 measurements more than doubles (to 38 %) with the use of a plume model. Therefore, we argue that a plume model with detailed and accurate dispersion parameters is crucial for top-down monitoring of greenhouse gas emissions in urban environments. Future research could benefit from assimilating observed wind fields to improve the plume representation at urban scales.
Ship borne rotating shadow band radiometer observations for the
determination of multi spectral irradiance components and direct
sun products for aerosol
Authors: Witthuhn Jonas , Deneke Hartwig , Macke Andreas , Bernhard Germar
Published: September 2016

Abstract. The 19 channel rotating shadow band radiometer GUVis-3511 built by Biospherical Instruments is introduced as an instrument which is able to provide automated ship borne measurements of the direct, diffuse and global spectral irradiance components without a requirement for stabilization. Several direct sun products, including spectral direct beam transmittance, aerosol optical depth, Angström exponent, and precipitable water can be derived from these observations. The individual steps of the data analysis are described, and the different sources of uncertainty are discussed. The total uncertainty of the observed direct beam transmittances is estimated to be 4.24 % at 95 % CI for ship borne operation. The calibration is identified as the dominating contribution to the total uncertainty. A comparison of direct beam transmittance with those obtained from a Cimel sun photometer at a land site and a manually operated Microtops II sun photometer on a ship is presented, yielding relative deviations of less than 3 % and 4 % on land and on ship, respectively, for most channels and in agreement with our previous uncertainty estimate. These numbers demonstrate that the instrument is well suited for ship borne operation, and the applied methods for motion correction work accurately. Based on spectral direct beam transmittance, aerosol optical depth at 510 nm can be retrieved with an uncertainty of 0.0032 for a 95 % CI. Only minor deviations occur due to the different methods used for estimating Rayleigh scattering and gas absorption optical depths, as implemented by AERONET and in our processing. Relying on the cross-calibration of the 940 nm water vapor channel with the Cimel sun photometer, the column amount of precipitable water has been estimated with an uncertainty of +−0.034 cm. More research is needed to estimate the accuracy of the instrument for low sun (solar zenith angles larger than 70°) and during periods with strong swell.
A glaciochemical study of 120 m ice core from Mill Island, East
Antarctica
Authors: Inoue Mana , Curran Mark A. J. , Moy Andrew D. , van Ommen Tas D. , Fraser Alexander D. , Phillips Helen E. , Goodwin Ian D.
Published: September 2016

Abstract. A 120 m ice core was drilled on Mill Island, East Antarctica (65°30’ S, 100°40’ E) during the 2009/2010 Australian Antarctic field season. Contiguous discrete 5 cm samples were measured for hydrogen peroxide, water stable isotopes and trace ion chemistry. The ice core was annually dated using a combination of chemical species and water stable isotopes. The Mill Island ice core preserves a climate record covering 97 years from 1913 to 2009 C.E., with a mean snow accumulation of 1.35 m (ice-equivalent) per year (mIE yr−1). This northernmost East Antarctic coastal ice core site displays trace ion concentrations that are generally higher than other Antarctic ice core sites (e.g., mean sodium levels were 254 μEq L−1). The trace ion record at Mill Island is characterised by a unique and complex chemistry record with three distinct regimes identified. The trace ion record in Regime A displays clear seasonality from 2000 to 2009 C.E.; Regime B displays elevated concentrations with no seasonality from 1934 to 2000 C.E.; and Regime C displays relatively low concentrations with seasonality from 1913 to 1934 C.E. Sea salts were compared with instrumental data, including atmospheric models and satellite-derived sea ice concentration, to investigate influences on the Mill Island ice core record. The mean annual sea salt record does not correlate with wind speed. Instead, sea ice concentration to the east of Mill Island likely influences the annual mean sea salt record. A mechanism involving formation of frost flowers on sea ice is proposed to explain the extremely high sea salt concentration. The Mill Island ice core records are unexpectedly complex, with strong modulation of the trace chemistry on long timescales.
A complete glacier inventory of the Antarctic Peninsula based on Landsat7 images from 2000–2002 and other pre-existing datasets
Authors: Huber Jacqueline , Cook Alison J. , Paul Frank , Zemp Michael
Published: September 2016

Abstract. The glaciers on the Antarctic Peninsula (AP) potentially make a large contribution to sea level rise. However, this contribution has been difficult to estimate, as no complete glacier inventory (outlines, attributes, separation from the ice sheet) has been available. This work fills the gap and presents a new glacier inventory of the AP north of 70° S, based on digitally combining pre-existing datasets with GIS techniques. Rock outcrops have been removed from the glacier basin outlines of Cook et al. (2014) by digital intersection with the latest layer of the Antarctic Digital Database (Burton-Johnson et al., 2016). Glacier-specific topographic parameters (e.g. mean elevation, slope and aspect) as well as hypsometry have been calculated from the Digital Elevation Model (DEM) of Cook et al. (2012). We also assigned connectivity levels to all glaciers following the concept by Rastner et al. (2012). Moreover, the bedrock dataset of Huss and Farinotti (2014) enabled us to add ice thickness and volume for each glacier. The new inventory is available from the GLIMS database (doi:10.7265/N5V98602) and consists of 1589 glaciers covering an area of 95 273 km2, slightly more than the 90 000 km2 covered by glaciers surrounding the Greenland Ice Sheet. The total ice volume is 34 590 km3, of which 1/3 is below sea level. The hypsometric curve has a bimodal shape due to the unique topography of the AP, which consists mainly of ice caps with outlet glaciers. Most of the glacierized area is located at 200–500 m a.s.l. with a secondary maximum at 1500–1900 m. Approximately 63 % of the area is drained by marine-terminating glaciers, and ice shelf tributary glaciers cover 35 % of the area. This combination indicates a high sensitivity of the glaciers to climate change for several reasons: (1) only slightly rising equilibrium line altitudes would expose huge additional areas to ablation, (2) rising ocean temperatures increase melting of marine terminating glaciers, and (3) ice shelves have a buttressing effect on their feeding glaciers and their collapse would alter glacier dynamics and strongly enhance ice loss (Rott et al., 2011). The new inventory should facilitate modelling of the related effects using approaches tailored to glaciers for a more accurate determination of their future evolution and contribution to sea level rise.
Variational assimilation of IASI SO2 plume height and total-column
retrievals in the 2010 eruption of Eyjafjallajökull using the SILAM
v5.3 chemistry transport model
Authors: Vira Julius , Carboni Elisa , Grainger Roy G. , Sofiev Mikhail
Published: September 2016

Abstract. This study focuses on two new aspects on inverse modelling of volcanic emissions. First, we derive an observation operator for satellite retrievals of plume height, and second, we solve the inverse problem using the 4D-Var method. The approach is demonstrated by assimilating IASI SO2 plume height and total column retrievals in a source term inversion for the 2010 eruption of Eyjafjallajökull. The inversion resulted in temporal and vertical reconstruction of the SO2 emissions during the 1–20 May, 2010 with formal vertical and temporal resolutions of 500 m and 12 hours. The plume height observation operator is based on simultaneous assimilation of the plume height and total column retrievals. The plume height is taken to represent the vertical centre of mass, which is transformed into the first moment of mass. This makes the observation operator linear and simple to implement. The necessary modifications to the observation error covariance matrix are derived. Regularisation by truncated iteration is investigated as a simple and efficient regularisation method for the 4D-Var based inversion. In an experiment with synthetic observations, the truncated iteration was found to perform similarly to the commonly used Tikhonov regularisation. However, the truncated iteration allows the amount of regularisation to be varied a posteriori, without repeating the inversion. For inverting the Eyjafjallajökull SO2 emission at the temporal and vertical resolution used in this study, the 4D-Var method required about 70 % less computational effort than commonly used methods based on performing a separate model simulation for each degree of freedom in the estimated source term. Compared to the inversion using only total column retrievals, assimilating the plume height resulted in a vertical emission profile more closely matching the ash plume heights observed by radar. The a posteriori source term gave an estimate of 0.29 Tg erupted SO2 of which 95 % was injected below 11 km.
Configuration synthesis of generalized deployable units via group theory
Authors: Li Tuanjie , Jiang Jie , Dong Hangjia , Zhang Lei
Published: September 2016

Abstract. The generalized deployable mechanism is composed of generalized links and generalized kinematic pairs. The generalized links include the flexible members, springs, and cables etc. The generalized kinematic pairs include the preloaded kinematic pairs and flexible hinges etc. The generalized deployable mechanism consists of generalized deployable units. Based on group theory, this paper presents a brief and effective configuration synthesis method for generalized deployable units which is composed of generalized links and generalized kinematic pairs expressed by group. The permutation group is used to obtain all the permutation types of generalized kinematic pairs and generalized links. The configuration matrix of generalized deployable unit is established through combining permutation group, and the topological configurations of generalized deployable units are created. The combining rules of groups are developed. The method of isomorphism detection is used to ensure the uniqueness of configurations. The configurations of generalized deployable units including four and six generalized links are generated respectively.

A cell line was established from embryo cells of rose bitterling Rhodeus ocellatus ocellatus (Teleostei: Acheilognathinae). This cell line is maintained for more than seven years in my laboratory. Karyotype in it does not have the change either. In maintenance of the biological diversity, it is an important problem to demand a method to prevent the extinction of the species. This cell line will become the clue of the study of the embryonic stem cell in endangered species. On the other hand, this cell line which karyotype is stable in its will be a useful tool for a mutagenicity assay.

There are little economic data concerning the profitability of organic vegetable crops in the Southern Coastal Plain, especially in reference to sod-based rotation and tillage alternatives.  A three-year experiment was conducted at the North Florida Research and Education Center-Quincy involving a crop rotation sequence of oats and rye (winter), bush beans (spring), soybean (summer) and broccoli (fall). Bush beans and broccoli were the cash crops. This paper presents analyses of the riskiness of organic production utilizing years in bahiagrass prior to initiating the crop rotation sequence and conventional tillage (CT) versus strip tillage (ST). Methods of “Risk-rated enterprise budget” and “Analyses of Variance-Covariance Matrix (ANOVA)” were utilized for determining relative profitability, and coefficient of variation was applied for measuring riskiness of each treatment. Three years of bahiagrass prior to initiating the crop rotation sequence, in combination with conventional tillage, had the highest profitability and ranked as the least risky scenario.  The second most profitable treatment was conventional tillage with four years of bahiagrass. Focusing on strip tillage, four years of bahiagrass with strip-tillage ranked third in term of profitability.

Het belonen van commissarissen in aandelen: alignment versus onafhankelijkheid?

In een tijdsgewricht waarin de aan bestuurders van Nederlandse beursvennootschappen toegekende beloningen steeds breed worden uitgemeten in de landelijke media en publieke ophef tot gevolg hebben, is het evident dat de beloning als onderwerp terug zou komen in het consultatievoorstel tot herziening van de Corporate Governance Code. De auteur bespreekt de voorgestelde principes en best practice bepalingen over de beloning, waarbij hij ingaat op het voorstel om het mogelijk te maken commissarissen in aandelen te belonen. De vraag rijst of met het belonen van commissarissen in de vorm een variabele beloning de onafhankelijkheid van deze commissarissen in het geding komt.
EGTA, a calcium chelator, affects cell cycle and increases DNA methylation in root tips of Triticum aestivum L.

Published: September 2016

In this study, when germinated Triticum aestivum L. seeds were treated with 0, 2, 4 and 6 mM ethyl glycol tetraacetic acid (EGTA), root growth was suppressed and the mitotic index decreased. These inhibitory effects were positively correlated with EGTA concentration. RT-PCR analysis revealed that the expression of several gene markers related to the G1/S transition of the cell cycle were significantly downregulated. Confocal microscopy of Fluo-3/AM-stained roots showed chelation of nearly all of the Ca2+ within the root meristematic regions. Both random amplified polymorphic DNA (RAPD) and coupled restriction enzyme digestion-random amplification (CRED-RA) techniques showed significant increases in the levels of genomic DNA polymorphisms and degree of DNA methylation. The study provides information concerning the impact of Ca2+ chelator, EGTA, on the growth, expression of cell cycle transition marker genes, and changes in DNA structure and methylation in the wheat roots.

A performance validation of the ANSR® for Campylobacter method was conducted in selected matrixes. This assay used selective nicking enzyme amplification technology to amplify target genes. Samples were enriched for 20 to 24 h and then lysed. The assay was completed within 50 min using real-time detection in a combination incubator/fluorescence detector and software. When 50 distinct strains of Campylobacter jejuni, C. lari, or C. coli were tested for inclusivity, all 50 strains produced positive results. In exclusivity testing, 31 strains of related organisms, including seven nontarget Campylobacter strains and other common species, were evaluated. All 31 species generated negative ANSR assay results, including the nontarget Campylobacter strains. The ANSR for Campylobacter method was compared to the U.S. Department of Agriculture, Food Safety and Inspection Service Microbiology Laboratory Guidebook reference method using naturally contaminated chicken carcass rinse or turkey carcass sponge samples. ANSR method performance was not statistically different from the reference method using two different enrichment options. Equivalent results were observed at both time points (20 and 24 h) and in both atmospheres (microaerobic and aerobic) to reference methods. Method performance with chicken carcass rinse was confirmed in an independent laboratory study. Additionally, in robustness testing, small, deliberate changes to the assay parameters minimally affected ANSR method performance. Finally, accelerated stability results from three independently manufactured lots supported a shelf life of 6 months when stored at 4°C. The ANSR assay offered greater efficiency and flexibility when compared to the reference method with a 20–24 h single-step enrichment in a microaerobic or an aerobic atmosphere.

O DSM-V e suas implicações no processo de medicalização da existência
Authors: Resende Marina Silveira de , Pontes Samira Paula , Calazans Roberto
Published: September 2016

O lançamento da quinta edição do Manual Diagnóstico e Estatístico de Transtornos Mentais (DSM), fruto de um demorado processo de revisão do DSM-IV-TR, acarretará em mudanças na estrutura do próprio manual, que passará de um modelo de diagnóstico categorial para um modelo longitudinal. Tais mudanças proporcionarão um caráter preditivo aos diagnósticos. Nosso objetivo é discutir as implicações de algumas novas categorias diagnósticas propostas pelo DSM-V, no que tange, principalmente, no fortalecimento do movimento de medicalização da existência. Apontamos como um dos principais desencadeadores dessa medicalização o fato de que os DSM’s deixam de ter um uso exclusivamente clínico. Para isso, apresentamos o aumento do número de vendas de medicamentos psiquiátricos no Brasil como um indicador desse movimento de medicalização da existência.
mASH1 is Highly Specific for Neuroendocrine Carcinomas: An Immunohistochemical Evaluation on Normal and Various Neoplastic Tissues
Authors: Altree-Tacha David , Tyrrell Jillian , Li Faqian
Published: September 2016

Context.—High-grade neuroendocrine carcinomas and carcinoids can arise in different sites such as lung, gastrointestinal tract, prostate, and skin. Classic neuroendocrine markers such as CD56, synaptophysin, and chromogranin cannot distinguish carcinoids from high-grade neuroendocrine carcinomas. Recently, mouse monoclonal mASH1 has been shown to help discriminate carcinoids from high-grade neuroendocrine carcinomas in various neoplastic sites. To date, there have been no comprehensive immunohistochemistry studies with mASH1 on nonneuroendocrine neoplasms.

Objective.—To evaluate the specificity and sensitivity of mASH1 in various normal and neoplastic tissues, including lung cancers.

Design.—Formalin-fixed, paraffin-embedded tissue microarrays consisting of normal tissues and various neoplastic tissues were immunohistochemically evaluated with mASH1.

Results.—In normal tissues (n = 30), mASH1 (nuclear staining) was sparsely expressed in the molecular cell layer, white matter, and granular cell layer of cerebellum; C cells in thyroid; and epithelial cells in thymus. In lung cancers, mASH1 stained 1.1% (1 of 93) of adenocarcinomas, 0.9% (1 of 111) of squamous cell carcinomas, 0% (0 of 30) of large cell carcinomas, 66.7% (6 of 9) of large cell neuroendocrine carcinomas, and 82.5% (94 of 114) of small cell carcinomas. In various other neoplastic tissues (n = 1114), mASH1 was expressed in thyroid medullary carcinomas, thymic carcinomas, and brain cancers; mASH1 was also expressed in a very low percentage of breast carcinomas, ovarian cancers, and pancreatic neuroendocrine tumors. All typical carcinoids of various sites were negative (0 of 11), however, in lung atypical carcinoids, mASH1 was expressed in 42.9% (9 of 21).

Conclusions.—Although not organ specific, mASH1 is highly specific for high-grade neuroendocrine carcinomas versus carcinoids and other nonneuroendocrine neoplasms.
Diagnostic Approach to Advanced Fibrotic Interstitial Lung Disease: Bringing Together Clinical, Radiologic, and Histologic Clues

Published: September 2016

Context.—

Idiopathic pulmonary fibrosis (IPF) is a distinctive clinicopathologic entity and the most common form of progressive diffuse lung scarring in older adults. Idiopathic pulmonary fibrosis manifests histopathologically as the usual interstitial pneumonia pattern. The usual interstitial pneumonia pattern is distinguished by geographically and temporally heterogeneous fibrosis that is peripherally accentuated, often with honeycombing and traction bronchiectasis. Idiopathic pulmonary fibrosis is not the only disease that leads to end-stage lung fibrosis, however, and several other entities may also cause advanced fibrosis. Surgical lung biopsies often present a diagnostic dilemma when they show clear evidence of advanced fibrosis, but the clinical, imaging, and/or histopathologic subcharacteristics suggest something other than IPF.

Objective.—

To address this dilemma, we review several other fibrotic lung diseases, including connective tissue disease–associated interstitial lung disease, chronic hypersensitivity pneumonitis, advanced pulmonary Langerhans cell histiocytosis, end-stage pulmonary sarcoidosis, Erdheim-Chester disease, Hermansky-Pudlak syndrome, and others, detailing their clinical, radiologic, and histopathologic attributes and emphasizing similarities to and differences from IPF.

Data Sources.—

Data sources comprised published peer-reviewed literature and personal experience of the authors.

Conclusions.—

Often, clues in the lung biopsy may offer the first suggestion of a fibrotic lung disease other than IPF, and accurate classification is important for prognosis, treatment, and the development of future therapies.
