Ca2+ Influx and Tyrosine Kinases Trigger Bordetella Adenylate Cyclase Toxin (ACT) Endocytosis. Cell Physiology and Expression of the CD11b/CD18 Integrin Major Determinants of the Entry Route

Humans infected with Bordetella pertussis, the whooping cough bacterium, show evidences of impaired host defenses. This pathogenic bacterium produces a unique adenylate cyclase toxin (ACT) which enters human phagocytes and catalyzes the unregulated formation of cAMP, hampering important bactericidal functions of these immune cells that eventually cause cell death by apoptosis and/or necrosis. Additionally, ACT permeabilizes cells through pore formation in the target cell membrane. Recently, we demonstrated that ACT is internalised into macrophages together with other membrane components, such as the integrin CD11b/CD18 (CR3), its receptor in these immune cells, and GM1. The goal of this study was to determine whether ACT uptake is restricted to receptor-bearing macrophages or on the contrary may also take place into cells devoid of receptor and gain more insights on the signalling involved. Here, we show that ACT is rapidly eliminated from the cell membrane of either CR3-positive as negative cells, though through different entry routes, which depends in part, on the target cell physiology and characteristics. ACT-induced Ca2+ influx and activation of non-receptor Tyr kinases into the target cell appear to be common master denominators in the different endocytic strategies activated by this toxin. Very importantly, we show that, upon incubation with ACT, target cells are capable of repairing the cell membrane, which suggests the mounting of an anti-toxin cell repair-response, very likely involving the toxin elimination from the cell surface.

Desarrollo de una aplicación web de localización en las facultades de la UPV/EHU

En este Proyecto de Fin de Carrera se ha creado la aplicación web FindPlace, así como su web de administración FindPlaceAdmin. La finalidad de FindPlace es poner a disposición del usuario la información sobre las ubicaciones (laboratorios, aulas, despachos, etc.) y detalles acerca del personal de cualquier facultad asociada a la UPV/EHU. FindPlace ha sido implementada con un Responsive Web Design, lo cual permite que la página web se visualice adecuadamente independientemente del dispositivo en el que se represente. Para la consecución de este proyecto se ha seguido una metodología ágil que ha permitido que la idea inicial haya ido evolucionando y adaptándose a las nuevas necesidades surgidas a lo largo del desarrollo.

Limited resources? Let the habitat priority planner help!

In this time of scarce resources, coastal resource managers must find ways to prioritize conservation, land use, and restoration efforts. The Habitat Priority Planner (HPP) is a free geospatial tool created by the National Oceanic and Atmospheric Administration’s Coastal Services Center that has received wide praise for its ease of use and broad applicability to conservation strategic planning, restoration, climate change scenarios, and other natural resource management actions. Not a geographic information system (GIS) user? Don’t worry―this tool was designed to be used in a team setting. One intermediate-level GIS user can push the buttons to show quick results while a roomful of resource managers and stakeholders provide input criteria that determine the results. The Habitat Priority Planner is a toolbar for ESRI’s ArcGIS platform that is composed of three modules: Habitat Classification, Habitat Analysis, and Data Explorer. The tool calculates basic ecological statistics that are used to examine how habitats function within a landscape. The tool pre‐packages several common landscape metrics into a user‐friendly interface for intermediate GIS users. In addition, HPP allows the user to build queries interactively using a graphical interface for demonstrating criteria selections quickly in a visual manner that is useful in stakeholder interactions. Tool advocates and users include land trusts, conservation alliances, nonprofit organizations, and select National Estuarine Research Reserves and refuges of the U.S. Fish and Wildlife Service. Participants in this session will learn the basic requirements for HPP use and the multiple ways the HPP has been applied to geographies nationwide. (PDF contains 5 pages)

A Convergent Synthetic Route to the Tunicamycin Antiobiotics. Synthesis of (+)-Tunicamycin V

A concise synthetic route to the tunicamycin antibiotics is described, illustrated by the preparation of (+)-tunicamycin-V (1-V). Key features of the synthesis include: (1) the development and application of a silicon-mediated reductive coupling of aldehydes and allylic alcohols to construct the undecose core of the natural product; and (2) the development of an efficient procedure for the synthesis of the trehalose glycosidic bond within the antibiotic. These innovations allow for the coupling of a uridine-derived aldehyde fragment with a preformed trehalose-linked disaccharide allylic alcohol to form the carbohydrate core (1) of the natural product in a highly convergent manner. The resultant amino polyol is a versatile intermediate for the synthesis of any of the homologous tunicamycin antibiotics.

Comment: Food web interactions and biomanipulation in Australian reservoirs

The authors have been studying the control of phytoplankton biomass in several Australian reservoirs. To manipulate fish communities in order to reduce phytoplankton biomass, one needs a thorough understanding of processes in the plankton-associated food webs. In contrast to the situation found in lakes of the northern hemisphere, the planktivorous fish of Australian reservoirs are relatively small and they may deplete small rather than large zooplankters, so that animals as large as the adults of Daphnia carinata may avoid predation. This would result in promotion of Daphnia, particularly if fish eliminate its smaller competitors. The aim of biomanipulation should be the establishment and maintenance of a proper ratio of planktivores/piscivores, adequate for water quality requirements. Successful selection of the appropriate ratio for a given reservoir will depend on the extent of our understanding of its food web interactions. For practical application of biomanipulation in management, further development of the food web theory under Australian conditions is needed.

BLOG: da Internet à sala de aula

Os diários de escrita íntima constituem tipo de texto do domínio confessional. Apresentam narrativas pessoais com características específicas ao gênero, como datação, marcas de subjetividade, escrita informal e coloquialidade. Durante muitos anos, eram escritos em cadernos e guardados a sete chaves por seus autores para que não fossem lidos por outras pessoas. Por volta dos anos 80, surgiram as agendas de adolescentes. Aproveitando o modelo pré-definido industrialmente, as agendas eram preenchidas dia a dia, como um diário, mas com a novidade do acréscimo de elementos semióticos, como fotos, papéis de bala, recortes de revistas, entre outros. Além disso, traziam como diferencial a presença de um leitor participativo: os textos eram compartilhados com amigos, e bilhetes e comentários eram escritos nas páginas das agendas. Com o advento da Internet, o diário e a agenda se fundem no blog que aproveita os recursos do suporte virtual para tornar o gênero interativo, hipertextual e multimídia, acentuando o processo de leitura e de escrita nos jovens produtores de blogs. Paralelamente, a escrita se torna grande ferramenta de comunicação no ambiente virtual, adquirindo características peculiares em função da rapidez na comunicação e da economia de digitação. A partir da teoria de Bakthin sobre gêneros do discurso e do conceito de gêneros digitais de Marcuschi, a pesquisa apresenta como objeto perceber e elencar categorias pertinentes aos gêneros diário e blog para analisá-las e compará-las, na intenção de mapear um possível percurso dos diários aos blogs de adolescentes, discutindo o contraste público-privado na escrita íntima, bem como suas principais marcas linguísticas, percebendo vantagens e desvantagens de sua utilização como ferramenta auxiliar no processo de aprendizagem da escrita e da leitura de Língua Portuguesa. A pesquisa foi motivada pela discussão de que a escrita digital pode prejudicar o desenvolvimento da produção textual de jovens em formação, o que não se confirmou, visto que a estrutura sintática da língua se mantém, e que a variação acontece apenas no nível vocabular, não interferindo na comunicação. Os resultados apontam para a utilização de blogs na educação como complementação do material pedagógico e como incentivo à leitura, à escrita, à construção da argumentação e do posicionamento crítico, aproximando a escola da vida cotidiana dos estudantes

La divulgación de información financiera en las páginas web de las empresas cotizadas

[ES] Es obligatorio para las empresas cotizadas que cuenten con una página web para atender el derecho de información de los accionistas, y donde difundir información relevante y obligatoria. Por ello, se creó la normativa necesaria para regular tanto la información mínima que las empresas debían aportar en sus webs, como los requisitos técnicos y jurídicos que dichas páginas debían poseer. No obstante, todas las empresas no presentan la misma información en sus webs, ya que muchas no se limitan a presentar solo la exigida por ley, y ésta puede ser más o menos útil para los usuarios. Por eso, es imprescindible poder conocer de alguna forma la transparencia que las empresas muestran a los usuarios en sus páginas web y en particular a los accionistas, si existe asimetría informativa o no, y saber cuál es el grado de calidad de la información presentada, así como la confianza que se puede tener en la misma.

Galveston Bay Migrates to the Web; DSpace Comes to Texas

This presentation describes how the Galveston Bay Bibliography and Galveston Bay Information Center projects transitioned from a paper world to electronic format. The mission of the Galveston Bay Information Center (GBIC) is to serve as a repository for information and a resource for research on Galveston Bay, its watershed, and the coastal region for all members of the Galveston Bay Community. GBIC was created in response to critical losses of data and information that were identified in the early stages of Galveston Bay National Estuary Program and includes a physical collection as well as a bibliography. With the loss of funding imminent, the administrators of GBIC recognized the need to preserve the collection and its digital bibliography in perpetuity. Enter Texas Digital Library. The University’s participation in TDL enabled GBIC to make the Galveston Bay Bibliography more robust and visible to the entire world.
