RCN4GSC Workshop Report: Managing Data at the Interface of Biodiversity and (Meta)Genomics, March 2011.

Building on the planning efforts of the RCN4GSC project, a workshop was convened in San Diego to bring together experts from genomics and metagenomics, biodiversity, ecology, and bioinformatics with the charge to identify potential for positive interactions and progress, especially building on successes at establishing data standards by the GSC and by the biodiversity and ecological communities. Until recently, the contribution of microbial life to the biomass and biodiversity of the biosphere was largely overlooked (because it was resistant to systematic study). Now, emerging genomic and metagenomic tools are making investigation possible. Initial research findings suggest that major advances are in the offing. Although different research communities share some overlapping concepts and traditions, they differ significantly in sampling approaches, vocabularies and workflows. Likewise, their definitions of 'fitness for use' for data differ significantly, as this concept stems from the specific research questions of most importance in the different fields. Nevertheless, there is little doubt that there is much to be gained from greater coordination and integration. As a first step toward interoperability of the information systems used by the different communities, participants agreed to conduct a case study on two of the leading data standards from the two formerly disparate fields: (a) GSC's standard checklists for genomics and metagenomics and (b) TDWG's Darwin Core standard, used primarily in taxonomy and systematic biology.

CABARET: MIRROR OF SOCIETIES

The basic definition of a cabaret is a café that offers live entertainment performed by singers, musicians and dancers and serves food and drink. It is generally housed in small, intimate spaces. Starting in the middle of the nineteenth century, artists, composers and writers met at Parisian cafés and salons to share their works. The cabaret was a suitable place for social activities. Artists could meet, discuss their opinions, and share their art in a relaxed setting. Even though cabaret music was often based on popular idioms, social and political commentary coupled with satirical settings represented the true soul of the genre. This trend flourished in the late nineteenth and early twentieth centuries. The first cabaret in Paris, Le Chat Noir inspired the growth of similar places in major cities throughout Europe besides Paris. The three recitals that comprise this dissertation project were performed at University of Maryland venues: the Robert & Arlene Kogod Theatre on 11 May 2011, Ulrich Recital Hall on 4 December 2011, and Gildenhorn Recital Hall on 4 March 2012. The repertoire for the first recital included works by Erik Satie with mezzo-soprano Monica Soto-Gil, Friedrich Hollaender with soprano Gabrielle DeMers, William Bolcom with baritone Ethan Watermeier and mezzo-soprano Stepanie Sadownik, and Poulenc with baritone Andrew McLaughlin. André Previn‘s Tango Song and Dance with violinist Jennifer Kim served as the instrumental interlude. The second recital included songs by Friedrich Hollaender with mezzo-soprano Monica Soto-Gil, Hanns Eisler and Viktor Ullmann with mezzo-soprano Stephanie Sadownik, and Mischa Spoliansky with soprano CarrieAnne Winter. Victor Hollaender‘s Romance and Albumblatt were the instrumental interludes with violinist Jennifer Kim. The last recital featured works for piano and violin, the Graceful Ghost Rag by William Bolcom with violinist Jenny Wu, Four Souvenirs by Paul Schoenfield with violinist Jennifer Kim, Cabaret Songs by Benjamin Britten with soprano Linda Mabbs, and Souvenirs for piano four-hands by Samuel Barber with pianist Rita Sloan. The recitals were recorded on compact discs and are archived within the Digital Repository at the University of Maryland (DRUM).

Ambient Noise in the Kitimat Fjord System

Sound is an important medium for communication and marine organisms have evolved to capitalize on the efficiency with which sound energy travels through water. Anthropogenic and natural sound sources contribute to ocean ambient noise, which can interfere with the use of this sensory modality by marine animals. Anthropogenic noise sources have been increasing steadily over recent decades largely due to coastal population growth, increased global transportation, and offshore industrialization. Understanding the potential impacts of anthropogenic noise requires the establishment of ambient acoustic baselines from which to measure change. Establishing baselines, especially in quiet areas still largely unaffected by anthropogenic stressors, is particularly crucial in the face of the expansion of offshore industries, increasing coastal population and growing reliance on the ocean for global transportation. Global demand for liquid natural gas (LNG), catalyzed primarily by a growing Asian market, is expected to increase significantly in the next 20 years. The geographic position of British Columbia relative to these markets, a growing supply of LNG and new technology for extraction and shipping situate British Columbia as a strong competitor in the lucrative market. The LNG industry could have many adverse impacts on these territories and ecosystems. The Kitimat Fjord System is slated for the development of these LNG export facilities increasing shipping traffic for the port and thus increasing ambient noise in the fjord system. The purpose of this study is to 1) quantify the existing sound levels in the area surrounding Gil Island and 2) identify potential source mechanisms in order to provide a baseline study of the acoustic environment in the Kitimat Fjord system prior to potential increases from LNG shipping.

The methyl-CpG-binding protein MECP2 is required for prostate cancer cell growth.

The incidence of prostate cancer is increasing in western countries because of population aging. Prostate cancer begins as an androgen-dependent disease, but it can become androgen independent at a later stage or in tumors recurring after an antihormonal treatment. Although many genetic events have been described to be involved in androgen-dependent and/or -independent prostate cancer growth, little is known about the contribution of epigenetic events. Here we have examined the possibility that the methyl-CpG-binding protein MECP2 might play a role in controlling the growth of prostate cancer cells. Inhibition of MECP2 expression by stable short hairpin RNA stopped the growth of both normal and cancer human prostate cells. In addition, ectopic expression of the MECP2 conferred a growth advantage to human prostate cancer cells. More importantly, this expression allowed androgen-dependent cells to grow independently of androgen stimulation and to retain tumorigenic properties in androgen-depleted conditions. Analysis of signaling pathways showed that this effect is independent of androgen receptor signaling. Instead, MECP2 appears to act by maintaining a constant c-myc level during antihormonal treatment. We further show that MECP2-expressing cells possess a functional p53 pathway and are still responsive to chemotherapeutic drugs.

Estrategias de marketing para el posicionamiento de carne de cuy empacada al vacío en Abancay-Perú : el caso MyCuy'S

Dentro de la inmensa gama de recursos naturales identificamos en la ciudad de Abancay - Perú al cuy (Cavia cobayo). Actualmente, se incentiva su producción y crianza en forma masiva por parte de los gobiernos locales, regionales y ONGs, que buscan en un corto y mediano plazo la exportación de estos roedores. Su carne se presenta en diferentes formas: embutidos de cuy, envasados al vacío fresco y otras presentaciones. La ciudad de Abancay se ha constituido como uno de los importantes productores de carne de cuy en el departamento de Apurímac y cuenta con un enorme potencial por sus condiciones climáticas y sociales, por ello se estableció como mercado objetivo a los consumidores de Abancay ubicados en el departamento de Apurímac-Perú con una demanda potencial de 121.524 unidades al año. Las estrategias de marketing para el posicionamiento de la carne de cuy empacada al vacío en Abancay-Perú de la Empresa Embutidos San Juan, fueron basados en el Estudio de Mercado de Carne de Cuy en el departamento de Apurímac - Perú realizado por la ONG Copyme, la segmentación se basó en variables geográficas (Censo-INEI, 2007), psicográficas (donde se determinó la falta de costumbre de consumo de carne de cuy) y demográficas (frecuencia de compra en relación al nivel de ingreso, los consumidores con mayor frecuencia de compra pertenecen a los que tienen ingresos menores de USD 234), el posicionamiento en base a la marca y al lema `Una tradición para compartir en familia` pretende entrar a la mente de los consumidores asociando las costumbres y la tradición con el sabor exquisito y la naturalidad del producto, apartando a los consumidores de la idea errónea de confundirlo con rata.

Competencia y alelopatía en el sistema soja (Glycine max (L.) Merr.) - Maleza (Artemisia annua L.)

La maleza altamisa (Artemisia annua L.) interfiere con el cultivo de soja por competencia y alelopatía, moduladas por estreses bióticos y abióticos (e.g. densidad, herbicida). Los aleloquímicos de altamisa (e.g. artemisinina, aceite esencial) pueden afectar directamente el crecimiento del cultivo o, indirectamente, a través de Bradyrhizobium japonicum (bacteria fijadora de N). Comprender los efectos de las interacciones en el sistema soja-altamisa es agroecológicamente relevante para diseñar prácticas que optimicen la producción y minimicen el uso de insumos. El objetivo de esta tesis fue analizar las interferencias competitivas y alelopáticas entre soja-altamisa y su impacto sobre la nodulación y el rendimiento del cultivo ante cambios en la densidad de plantas y dosis de herbicida. La metodología incluyó ensayos en: (i) parcelas a campo con distintas combinaciones de densidades cultivo-maleza y niveles de alelopatía y de herbicida, (ii) macetas a campo con distintas fuentes de aleloquímicos (biomasa seca y verde de altamisa, artemisinina pura) y suelos (arcilloso y arenoso) y (iii) laboratorio con distintos tipos y niveles de aleloquímicos. (i) Altas densidades de altamisa junto con altos niveles de aleloquímicos en el suelo no redujeron el crecimiento y rendimiento de soja y promovieron la nodulación con o sin aplicación de dosis subletales de herbicida. (ii) El rendimiento fue mayor en presencia de aleloquímicos y sustrato arcilloso. La relación entre el rendimiento y el peso de los nódulos fue positiva y los mayores valores se registraron con biomasa seca de altamisa. (iii) La artemisinina y el aceite esencial provocaron un efecto sinérgico negativo sobre el crecimiento de B. japonicum. El efecto neto de las interacciones competitivas, alelopáticas y de mutualismo generadas entre soja y altamisa dependen no solo del ambiente explorado sino del nivel de organización estudiado. En condiciones de campo (parcelas y macetas), la interacción alelopática fue positiva o neutra, mientras que en laboratorio resultó negativa.
