‘Reading and [w]rocking’: Morality and musical creativity in the Harry Potter fandom
Authors: Hall Catherine
Published: August 2016

Wizard rock, often stylized in written form as ‘wrock’, creatively engages with and augments the content world of Harry Potter through musically and lyrically diverse performances. Fan studies centred on Harry Potter have often discussed the application of fictional heroism to real-world issues, and wizard rock musicians are frequently cited as fandom activists. However, there is little analysis of the music, lyrics and performances of wizard rock as it relates to the moral messages of the series. Focusing on the work of the first wizard rock band, Harry and the Potters, I unite ethnographic fieldwork with historical research and the study of myth to place wizard rock within a narrative of musical activism, fan creativity and morality in music. Similar to their heroes in the books, these musicians imbue their music and their self images with the series’ morals, historical tropes and archetypes. They make this morality tangible by donating proceeds of compilation albums or music subscription series sales to nonprofit organizations, and by weaving these messages into their music. I argue that the wizard rock community’s application of fictional heroism through music, lyrics and performance encourages fellow Harry Potter fans to embrace heroic qualities in the real world.
Recut and re-tuned: Fan-produced parody trailers
Authors: Deaville James
Published: August 2016

The term ‘recut’ designates a trailer that a fan has created by editing footage from a film or trailer to new sound (voice-over, sound effects and underscore). The resulting re-imagined audio-visual text typically presents a genre-shifted narrative that intertextually relates to the source material. The ‘re-tuning’ by fan-editors involves imposing a new soundtrack (usually music and/or narration) over reordered and edited images, like the adapted family-friendly ‘Shining’ (2005) from the horror film The Shining (Kubrick, 1980) or the horror trailer refashioning of ‘Mrs. Doubtfire – Recut’ (2009). The literature about ‘vidding’ and recutting provides a foundation for considering how fans provoke new meanings when they add or re-order voice-overs, sound effects and music in recut trailers. The fan-editor must creatively engage with genre-based cinematic trailer practices and traditions of musical signification in re-imagining the source text. Thus sound effects and electronically distorted music predominate in re-tuned horror trailers, like ‘Mrs. Doubtfire – Recut’ or ‘Scary Mary Poppins’ (2006), while light-hearted melodies and instrumentation prevail when adapting source material to create a recut comedy trailer (‘The Wicker Man’ 2006). Thus the recut and re-tuned trailer represents a transformative nexus of sight and sound within fandom.

Authors: Potharaju Santhi Priya , Prathypaty Santha Kumari , Chintala Ravi Kanth , Yendluri Durga Bai , Kolliboyana Jai Krishna Srikanth
Published: August 2016

Bone Morphogenetic Proteins (BMPs) are multifunctional growth factors and have the unique property of inducing stem and mesenchymal cell differentiation in to osteogenic cells, capable of producing bone. They are categorized under the super family Transforming Growth Factor-β (TGF-β). In the concept of tissue engineering they are the first approved therapeutic proteins to be used in conjunction with a scaffold and a biocompatible fixative device. Thus in this review the mechanism of action of BMPs is described at its cellular and molecular levels along with its potential clinical applications, utilization perspectives and scientific evidence in periodontal regeneration.

Determinants of Business Fixed Investment: Evidence from German Firm-Level Data
Authors: Buettner Thiess , Hoenig Anja
Published: August 2016

This paper employs a novel firm-level dataset that combines financial accounts of German firms with data from a business survey to shed new light on the demand for capital. The empirical analysis employs firm-specific indicators in order to explore the effects of sales, the cost of capital and indicators of the business climate, which are used by the ifo Institute to provide a leading indicator for the German economy. The empirical results support a robust significant effect of a firm’s cost of capital on the stock of capital with an elasticity not significantly different from –1. Controlling for sales, a good rather than normal business situation is found to be associated with about 8 % higher investment.
20 Gbps Bidirectional Transmission via Four Channels over Long-haul SMF in a WDM-PON Architecture using External Modulation Scheme
Authors: Das Anindya Sundar , Patra Ardhendu Sekhar
Published: August 2016

A novel architecture of bidirectional gigabit signal transport system over long-haul single-mode fiber (SMF) using wavelength division multiplexed passive optical network technique is proposed and demonstrated. In order to offer multimedia services of high bandwidth, four signals of 5 Gbps data rates are externally modulated and transmitted through four channels over 100-km SMF in uplink and downlink. In our proposed scheme, an excellent bit error rate, good Q-factor and clear eye diagrams are observed for both 100-km uplink and downlink transmission. This architecture has potential to transmit 4×5 Gbps over long-haul fiber backbone and it will be useful in future broadband communications.

The performance of the integrated data transmission of 160 Gbps data up to 5,000 km will be evaluated by means of signal-to-noise ratio, total received power, and eye diagram.
Forty years of language contact and change in Kupwar: A critical assessment of the intertranslatability model
Authors: Kulkarni-Joshi Sonal
Published: August 2016

This paper revisits the language contact situation in the Indian border town-village of Kupwar originally reported by Gumperz and Wilson (1971. Convergence and creolization: A case from the Indo-Aryan/Dravidian border. In D. Hymes (ed.),Pidgnization and creolization of languages, 151–168. Cambridge: CUP). The study presents evidence for morpho-syntactic variation and complexification in the contact varieties of the local languages, Marathi and Kannada. Similar patterns of variation are adduced from contact varieties of Marathi and Kannada from historical data as well as present-day border villages which, like Kupwar, have been traditionally bilingual. The synchronic and historical data point out methodological and theoretical limitations of the original study. The variation and complexity observed in the Kupwar varieties allow for a reconsideration of the notion of intertranslatability or isomorphism in convergence areas. While suggesting a possible geographically defined micro-linguistic area at the Marathi-Kannada frontier, the paper indicates that the recent re-drawing of state boundaries along linguistic lines may have initiated divergence in this convergence area.
Responsive methodology: Perspectives on data gathering and language documentation in India
Authors: Chelliah Shobhana L.
Published: August 2016

Linguists continue a longstanding debate about the best methods for data gathering for language description and documentation. Under discussion is whether data gathered through elicitation of targeted structures through translations from a contact language or elicitation of grammaticality judgments gathers data to accurately represent the structure of language or if it is necessary to integrate these elicitation methods with the analysis of naturalistic speech to produce reliable and reproducible data sets. Given that language data is central to the development of language science and that language science feeds into studies of human cognition and behavior, the stakes are high that we get our data right and that means we need to get our methods right. Based on fieldwork and analysis that I conducted on Meitei, a Tibeto-Burman language of Northeast India, I compare results from gathering information using targeted elicitation and data gathering that integrates hypothesis-driven text-based and topic-based elicitation. I will show how mini-elicitation schedules can be derived during text analysis and how such schedules provide clearer clues to language structure than elicitation based on pre-constructed questionnaires based on a non-language specific understanding of language universals.
Context! Or how to read thoughts in a foreign language
Authors: Zeisler Bettina
Published: August 2016

Based on personal experience during long term fieldwork in Ladakh, this article will discuss a special technique for field research. It will emphasise the need to access the speakers’ creative unconsciousness by applying the time-consuming ‘ping-pong game’, that is, by confronting every speaker with real language data, by rechecking each speaker’s statement with at least one other speaker, and by feeding back evaluations from a second or third speaker to an original speaker and back in an almost endless repetition. A special focus here will be on the collection of compounds showing the phenomenon of consonant migration and on data gathering with respect to verb semantics and verb valency.

Characterization of hereditarily reversible posets
Authors: Kukieła Michał
Published: August 2016

A poset P is called reversible if every order preserving bijective self map of P is an order automorphism. P is called hereditarily reversible if every subposet of P is reversible. We give a complete characterization of hereditarily reversible posets in terms of forbidden subsets. A similar result is stated also for preordered sets. As a corollary we extend the list of known examples of hereditarily reversible topological spaces.

A construction of a Peano curve
Authors: Harzheim Egbert
Published: August 2016

PEANO, G.: Sur une courbe, qui remplit toute une aire plane, Math. Ann. 36 (1890), 157–160] invented a surjective continuous mapping f of the unit interval I = [0, 1] onto I× I. A wellknown geometric construction was given by [HILBERT, D.: Über die stetige Abbildung einer Linie auf ein Flächenstück, Math. Ann. 38 (1891), 459–460]. In general Peano curves are constructed as limit of a series of piecewise linear functions. We here present another type of proof. A detailed survey on Peano curves is given in [WUNDERLICH, W.: Über Peano-Kurven, Elem. Math. 28 (1973), 1–10].

Letϕbe an injective, continuous, Lie product preserving map onMn(ℝ),n> 3. In the paper we show that then there exist an invertible matrixT∈Mn(ℝ) and a continuous functionψ:Mn(ℝ)→ ℝ, whereψ(A) = 0 for all matrices of trace zero, such that eitherϕ(A) =TAT−1+ψ(A)Ifor allA∈Mn(ℝ), orϕ(A) = −TAtT−1+ψ(A)Ifor allA∈Mn(ℝ). We determine that a similar proposition holds true for the setMn(ℂ),n> 3.

Authors: Khader M. M. , Adel M.
Published: August 2016

In this paper, we implement the fractional complex transform method to convert the nonlinear fractional Klein-Gordon equation (FKGE) to an ordinary differential equation. We use the variational iteration method (VIM) to solve the resulting ODE. The fractional derivatives are presented in terms of the Caputo sense. Some numerical examples are presented to validate the proposed techniques. Finally, a comparison with the numerical solution using Runge-Kutta of order four is given.

Authors: Singh Ajit K. , Yadav Vijay K. , Das S.
Published: August 2016

In this article, the active control method and the backstepping method are used during the synchronization of fractional order chaotic systems. The salient feature of the article is the analysis of time of synchronization between fractional order Chen and Qi systems using both the methods. Numerical simulation and graphical results clearly exhibit that backstepping approach is better than active control method for synchronization of the considered pair of systems, as it takes less time to synchronize while using the first one compare to second one.
Chaos suppression of Fractional order Willamowski–Rössler Chemical system and its synchronization using Sliding Mode Control
Authors: Rajagopal Karthikeyan , Karthikeyan Anitha
Published: August 2016

Most of the Real systems shows chaotic behavior when they approach complex states. Especially in physical and chemical systems these behaviors define the character of the system. The control of these chaotic behaviors is of very high practical importance and hence mathematical models of these chaotic systems proves vital in deciding the control structures. One such model of chemical reactors is the Willamowski–Rössler system (WR). In this paper we derive a fractional order sliding mode control scheme where the states of the WR system are driven back to the defined equilibrium points. We have also synchronized master and slave fractional order WR system using sliding mode control. As the entire control law is defined in fractional order, we derived a new methodology to prove the stability of the controller. The numerical simulation and analysis are achieved with LabVIEW.

Published: August 2016

El objetivo de éste estudio fue estudiar la composición y distribución espacial de cuatro órdenes de insectos acuáticos Ephemeroptera, Plecoptera, Trichoptera y Coleoptera (EPTC), en una quebrada de primer orden, Chanchamayo, Perú. Se realizaron colectas bimensuales desde marzo del 2013 a enero del 2014 en cuatro microhábitats lóticos: piedra, grava, musgo y hojas retenidas en la corriente. Fueron colectados un total de 7825 individuos agrupados en 51 géneros distribuidos en 27 familias de EPTC. El microhábitat de hoja retenida en los rápidos presentó la mayor abundancia, riqueza y diversidad de EPTC. Los géneros más representativos en términos de abundancia fueron Farrodes (10.35%), Phylloicus (10.01%) y Heterelmis (6.07%). La familia Elmidae fue la más diversa con 11 géneros. Las pruebas no parametricas de Kruskall-Wallis para riqueza, abundancia, diversidad y equidad determinaron diferencias significativas (p< 0.05) entre los micro hábitat estudiados. El análisis de ordenamiento no paramétrico de escalamiento multidimensional nMDS y el análisis de similaridad ANOSIM, evidenciaron diferencias claras entre las muestras de micro hábitats.
Diversidad y composición de murciélagos en los bosques montanos del Santuario Nacional Pampa Hermosa, Junín, Perú
Authors: Arias Edith , Pacheco Víctor , Cervantes Klauss , Aguilar Adela , Álvarez José
Published: August 2016

El Santuario Nacional Pampa Hermosa (SNPH) es un área protegida importante debido a que protege los relictos de los bosques montanos de las Yungas centrales del Perú, donde los estudios de la diversidad de murciélagos son escasos. Nuestro objetivo fue documentar la diversidad y composición de los murciélagos del SNPH y compararlo con otros bosques de las Yungas peruanas en el rango de 1200 – 2000 m. Se evaluaron cuatro localidades: Podocarpus (1900 m), Los Cedros (1600 m), Santa Isabel (1450 m) y Nueva Italia (1370 m). Se registraron 36 especies de murciélagos en las familias Phyllostomidae (30 spp.), Vespertilionidae (5 spp.) y Molossidae (1 sp.) con un esfuerzo de 560 redes-noche. Los estimadores Chao 1 y Chao 2 indicaron que se cubrió el 77% y 42% de las especies en la zona de estudio, respectivamente. Las curvas de rango-abundancia muestran a Carollia brevicauda como la más abundante en todas las localidades; se resalta la abundancia de Vampyressa melissa en las localidades de Los Cedros y Podocarpus. Se muestra una relación inversa significativa entre la riqueza de especies y la elevación (r = -0.90, P= 0.014). En rangos de 1200-1600 m, la riqueza del SNPH (35 spp.) fue mayor que en las otras Yungas presentando una mayor similitud con el Manu (Ij = 0.59); por otro lado, en rangos de 1600 – 2000 la riqueza del SNPH (14 spp.) fue la segunda más alta después del Manu (21 spp.), presentando una mayor similitud con San Ramón (Ij = 0.30). Los valores de complementariedad fueron altos entre el SNPH y los bosques de Yungas, entre 55-76% (1200-1600 m) y entre 70-83% en (1600-2000 m). Estos resultados indican que la diversidad β de los murciélagos en las Yungas peruanas es alta; sin embargo, debemos tomar en cuenta los esfuerzos dispares entre las localidades comparadas y que se requiere más trabajo de campo en zonas de vida y elevaciones aun no exploradas del SNPH para resultados más precisos.

La Reserva de Biósfera del Noroeste (RBN) alberga por lo menos 22 especies de mamíferos medianos y grandes entre las cuales se encuentran los primates Alouatta palliata aequatorialis y Cebus albifrons aequatorialis. Los estimados previos de la densidad poblacional de A. p. aequatorialis varían de 2.3‒8.6 ind/km2 en 1983 a 17‒19 ind/km2 en 2005 y 2006, respectivamente. Mientras que para C. a. aequatorialis no existen estimados poblacionales para la RBN. Para calcular la densidad poblacional de estas dos especies instalamos seis transectos lineales en 10.5 km2 dentro del Parque Nacional Cerros de Amotape (perteneciente a la RBN) de agosto del 2012 a marzo del 2013. En base a 112.3 km de transectos se obtuvo una densidad poblacional de 8.3 ± 3.6 ind/km2 para A. p. aequatorialis; sin embargo, por el reducido número de avistamientos de Cebus albifrons aequatorialis solo se pudo calcular el tamaño de grupo que varió de tres a 12 individuos y la tasa de encuentro de 0.3 ind/km. A pesar que la población del A. p. aequatorialis aparentemente ha aumentado, no es factible hacer comparaciones con los estimados anteriores debido a las diferentes metodologías empleadas y a la falta de aleatoriedad en la toma de datos. Recomendamos un plan de monitoreo a largo plazo, que incluya a C. a. aequatorialis como objeto y prioridad de conservación para la RBN, el cual debería incluir la mitigación de posibles amenazas como caza y captura para comercio de mascotas.

Currently biogeochemical models are used to understand and quantify key biogeochemical processes in the ocean. The objective of the present study was to validate predictive ability of a regional configuration of the PISCES biogeochemical model on main biogeochemical variables in Humboldt Current Large Marine Ecosystem (HCLME). The statistical indicators used to evaluate the model were the bias, root-mean-square error, correlation coefficient and, graphically, the Taylor’s diagram. The results showed that the model reproduces the dynamics of the main biogeochemical variables (chlorophyll, dissolved oxygen and nutrients); in particular, the impact of El Niño 1997-1998 in the chlorophyll (decrease) and oxygen minimum zone depth (increase). However, it is necessary to carry out sensitivity studies of the PISCES model with different key parameters values to obtain a more accurate representation of the properties of the Ocean.

El monitoreo de la pesquería de anchoveta en el Perú es de suma importancia para la sostenibilidad del ecosistema de Humboldt. El Programa de observadores a bordo Bitácoras de Pesca constituye una rica plataforma de recolección de datos de las embarcaciones durante sus viajes de pesca, y donde se recopila información acerca de las capturas en cada lance, distribuciones de tallas, descartes, captura incidental, captura por unidad de esfuerzo, entre otros. Para que los indicadores obtenidos a partir de esta información tengan robustez es preciso contar con un método de solidez estadística para el cálculo del número necesario de viajes a muestrear. Este trabajo presenta un método con estas características, para calcular el número óptimo de viajes de manera independiente para cada una de las variables y a diferentes escalas de tiempo. Se muestra que, dependiendo del objetivo y de la escala temporal, la cantidad óptima de viajes a muestrear varía. A partir de estos resultados, se proporcionan recomendaciones prácticas sobre el tamaño de muestra para el Programa Bitácoras de Pesca. También se discute la aplicabilidad de esta metodología para otros recursos pelágicos.

Published: August 2016

En este trabajo se presenta la estimación del descarte por exceso de captura en la pesquería industrial de cerco del stock Norte-Centro de anchoveta peruana. Se define el descarte por exceso de captura, como la porción de captura que se arroja al mar cuando se ha capturado más de lo que la capacidad de bodega de la embarcación puede almacenar. El análisis de estimación para el periodo 2005 - 2014, se realizó a partir del “Programa de observadores a bordo de la flota de cerco” que ejecuta el Instituto del Mar del Perú (IMARPE), en donde 5 837 viajes, que representan el 1.6% de los viajes totales, fueron muestreados. Las metodologías utilizadas en la estimación fueron: Modelo Lineal Generalizado (GLM) y el Modelo Delta. Las estimaciones por el Modelo Delta y el GLM fueron diferentes en magnitudes pero similares en tendencias, sin embargo la evaluación del funcionamiento del Modelo Delta, indica que este modelo se ajusta mejor a los datos. El Modelo Delta estimó que la pesquería descarta por exceso de captura entre 2 954 y 199 164 toneladas, con un promedio de 121 312 toneladas para el periodo de estudio, el cual representó una tasa del 2.6% en relación a los desembarques. Se sugiere la incorporación de variables espaciales (p. ej. distancia a la costa, latitud, longitud), físicas (TSM) y del comportamiento del cardumen (p.e. agregación), para mejorar el análisis y comprender mejor el comportamiento de este tipo de descarte.

ABSTRACT: This study examines the effect of inoculation with diazotrophic bacteria and nitrogen fertilization on the growth of micropropagated pineapple cv. 'Vitória' plantlets during the acclimatization period. The experiment was carried out in a greenhouse in Campos dos Goytacazes, in randomized blocks, using a 2x5x5 factorial scheme, with the factors being two types of inocula (absence or presence of a mixture of diazotrophic bacteria that contained Burkholderia sp. UENF 114111, Burkholderia silvatlantica UENF 11711, and Herbaspirillum seropedicae HRC 54), five levels of urea (0, 2, 5, 7, and 10g L-1), and five evaluation periods (30, 60, 90, 120, and 150 days following the planting of plantlets in trays), and with four replications of each treatment. An increase in the dried weight of shoots and roots of micropropagated pineapple cv. 'Vitória' plants depended on inoculation with diazotrophic bacteria, and plantlets acclimatization could be reduced by up to 57 days, depending on the concentration of urea fertilizer.

ABSTRACT: This study evaluated the efficiency of methods to overcome seed dormancy in different storage periods in the production of pecan seedlings. Seeds were submitted to the following treatments: T1, T4 and T7 - control treatments (seeds with no treatment, stored at room temperature for 30, 60 and 90 days, respectively), T2, T5 and T8 - stratification (seeds were distributed in boxes with wet sand maintained at a temperature of 4°C for 30, 60 and 90 days, respectively), T3, T6 and T9 - scarification + stratification (seeds scarified with sandpaper n.80 and stratified by 30, 60 and 90 days, respectively), in completely random experimental design. Plant height, stem diameter, number of leaves, full emergence and emergence speed index (ESI) were evaluated after 14 weeks of sowing. The best development of pecan 'plants, their emergence, and ESI were observed in the stratification treatment for 90 day as well as in the scarification + stratification treatment for 90 day. Storing seeds in uncontrolled environment reduced their viability.

Published: August 2016

ABSTRACT: The increasing development of DNA sequencing and genotyping technologies has made possible to analyze the genomes of several species. Genomic studies of production animals have greatly increased the understanding of mechanisms that control the interactions of genetic and environmental factors involved in the expression of traits of economic importance. Several technologies have been presented by different companies for the genotyping of low-density SNP panels, which may be used in different applications with different goals, such as paternity testing, diagnosis of genetic diseases, and identification of genetically superior animals based on polymorphisms characterized in candidate genes. The present review critically analyzes the GoldenGate Beadxpress technology and puts its use in these applications into perspective.

Published: August 2016

ABSTRACT: Recommendations for fertilizing irrigated rice in southern Brazil have been constantly evolving over years. In this process, the influence of factors such as the development cycle of varieties and sowing period increased. Thus, computational tools that take these and others important aspects into account can potentiate the fertilization response of rice. This study describes the computer program "ADUBARROZ". The software provides recommendations of fertilizer rates and liming requirements of irrigated rice, based on information entered by the user. The system takes various factors that regulate the crop response to fertilization into account. A final report is established with the graphical representation of input management over time.
De patológicos a higiênicos: os lares modernos e a imprensa no Brasil pós-Segunda Guerra Mundial
Authors: Kobayashi Elizabete Mayumy , Hochman Gilberto
Published: August 2016

Este artigo discute a patologização dos lares brasileiros como estratégia dos publicitários e anunciantes para convencer as donas de casa de que a solução dos problemas com insetos era o consumo de produtos industrializados. Eletrodomésticos, inseticidas e produtos de limpeza eram oferecidos como capazes de transformar as casas “doentes” em ambientes higiênicos e saudáveis. Nos anos de 1940 a 1960, o Brasil buscava consolidar seu parque industrial e seu mercado consumidor, o que tornava necessário substituir as soluções caseiras e tradicionais por produtos ditos modernos. O argumento deste trabalho é que essa oferta de soluções modernas para os problemas de manutenção de um lar salubre encontrou uma cultura da higiene já estabelecida nas classes médias urbanas brasileiras.

Published: August 2016

Abstract To verify the occurrence of natural Trypanosoma cruzi infection in non-human primates from a rural endemic area of the east region of Paraguay, xenodiagnosis was performed in 35 animals belonging to two species. For genotyping and T. cruzi discrete typing unit (DTU) assignment, a combination of four markers was used, including amplification products of the small (18S) and large (24Sα) subunits of ribosomal ribonucleic acid gene, the intergenic region of mini-exon gene and the heat shock protein 60 Eco-RV polymerase chain reaction-restriction fragment length polymorphism (HSP60/EcoRV-PCR-RFLP). One specimen of Sapajus cay was found positive and infected by the DTU TcII. This result constitutes the first record of natural T. cruzi infection in a sylvatic monkey in Paraguay, harbouring a DTU associated with severe Chagas disease in humans.

Published: August 2016

Abstract The Rhipicephalus (Boophilus) microplus complex currently consists of five taxa, namely R. australis, R. annulatus, R. (B.) microplus clade A sensu, R. microplus clade B sensu, and R. (B.) microplus clade C sensu. Mitochondrial DNA-based methods help taxonomists when they are facing the morpho-taxonomic problem of distinguishing members of the R. (B.) microplus complex. The purpose of this study was to perform molecular characterization of ticks in all five regions of Brazil and infer their phylogenetic relationships. Molecular analysis characterized 10 haplotypes of the COX-1 gene. Molecular network analysis revealed that haplotype H-2 was the most dispersed of the studied populations (n = 11). Haplotype H-3 (n = 2) had the greatest genetic differentiation when compared to other Brazilian populations. A Bayesian phylogenetic tree of the COX-1 gene obtained strong support. In addition, it was observed that the population of R. (B.) microplus haplotype H-3 exhibited diverging branches among the other Brazilian populations in the study. The study concludes that the different regions of Brazil have R. (B.) microplus tick populations with distinct haplotypes.

Background.

The frequency with which targeted tumor sequencing results will lead to implemented change in care is unclear. Prospective assessment of the feasibility and limitations of using genomic sequencing is critically important.

Methods.

A prospective clinical study was conducted on 100 patients with diverse-histology, rare, or poor-prognosis cancers to evaluate the clinical actionability of a Clinical Laboratory Improvement Amendments (CLIA)-certified, comprehensive genomic profiling assay (FoundationOne), using formalin-fixed, paraffin-embedded tumors. The primary objectives were to assess utility, feasibility, and limitations of genomic sequencing for genomically guided therapy or other clinical purpose in the setting of a multidisciplinary molecular tumor board.

Results.

Of the tumors from the 92 patients with sufficient tissue, 88 (96%) had at least one genomic alteration (average 3.6, range 0–10). Commonly altered pathways included p53 (46%), RAS/RAF/MAPK (rat sarcoma; rapidly accelerated fibrosarcoma; mitogen-activated protein kinase) (45%), receptor tyrosine kinases/ligand (44%), PI3K/AKT/mTOR (phosphatidylinositol-4,5-bisphosphate 3-kinase; protein kinase B; mammalian target of rapamycin) (35%), transcription factors/regulators (31%), and cell cycle regulators (30%). Many low frequency but potentially actionable alterations were identified in diverse histologies. Use of comprehensive profiling led to implementable clinical action in 35% of tumors with genomic alterations, including genomically guided therapy, diagnostic modification, and trigger for germline genetic testing.

Conclusion.

Use of targeted next-generation sequencing in the setting of an institutional molecular tumor board led to implementable clinical action in more than one third of patients with rare and poor-prognosis cancers. Major barriers to implementation of genomically guided therapy were clinical status of the patient and drug access. Early and serial sequencing in the clinical course and expanded access to genomically guided early-phase clinical trials and targeted agents may increase actionability.
