Health information outreach: the land-grant mission

Service to the state is one of the core principles of the land-grant mission. This concept of service is also fundamental to a significant number of outreach activities in academic health sciences libraries, particularly those libraries affiliated with the public land-grant universities. The Dana Medical Library at the University of Vermont has a lengthy tradition of outreach to health care providers and health care consumers of the State of Vermont. Building on the foundation of the land-grant institution—which grew out of federal legislation introduced in the mid nineteenth century by Justin Morrill, Vermont's congressional representative—the Dana Medical Library has based its outreach activities on its dedication of service to the state in the promotion of healthy citizens through information dissemination in support of health care delivery. Reengineering library services designed to meet the specific information needs of its diverse clientele, partnering with disparate health care organizations, and relying on fees for service to expand its outreach activities, the Dana Medical Library has redefined the concept of health information outreach for the new millennium.

Criação geográfica contemporânea

Esta reflexão de carácter exploratório pretende, como o próprio nome indica, ser um estudo preliminar das questões que se colocam com maior acuidade na contemporaneidade, no âmbito do ensino-aprendizagem da composição coreográfica. Partindo da (in)definição que caracteriza a Dança Contemporânea e os seus métodos e processos de criação, na qual é possível reconhecer como fundamental o desenvolvimento de percursos essencialmente singulares, pretendemos refletir sobre a necessidade de contribuir para o desenvolvimento das capacidades criativas dos intérpretes-criadores contemporâneos em contextos de formação. Esta é uma problemática que a nossa intervenção pedagógica e interesse profissional de forma plena justificam. Debruçamonos sobre a singularidade de dois projetos no âmbito da Criação Coreográfica Contemporânea Portuguesa, refletindo sobre aspetos da relação entre coreógrafo - intérprete - pesquisa - materialização do movimento. Pretendemos sublinhar a importância que reconhecemos do ensino-aprendizagem da composição coreográfica e a necessidade de o repensar na proximidade com as práticas artísticas atuais, procurando fazer emergir questões sobre a problemática aqui abordada.

Letter to the Selectmen of Charlestown, 1785 January 13

Three-and-a-half-page handwritten letter from "FM Dana by order &c," to the Selectmen of Charlestown. Dana is presumably speaking on behalf of the Selectmen of Cambridge and provides an extensive response to the Charlestown Selectmen about increased ferry fares that is critical of the demands of the Harvard Corporation.

Letter from Artemas Ward to Benjamin Stone, 1787 July 18

Artemas Ward wrote this letter to Benjamin Stone on July 18, 1787, expressing his concern about the expense of his son, Henry Dana Ward's, imminent studies at Harvard. Ward complains to Stone about his own debts and the failure of the government to honor their financial obligations to him, and he also expresses hope that the President of Harvard will allow his son to spend part of his time "keeping a school" during his freshman and sophomore years, thus earning an income sufficient to pay for his studies. Ward also suggests that it might be preferable that his son board with a respectable family, rather than live at the College.

Records identify the litigants, with some notes on fees and settlements; many of the cases concern debts. Justices of the peace include: Israel Atherton (Lancaster, Mass.); Samuel Dana (Amherst, N.H.); Joshua Longley (Shirley, Mass.); Nathaniel Paine (Worcester, Mass.); James Prescott (Westford, Mass.); Jeremiah Stiles (Keene, N.H.); William Swan (Groton, Mass.); Sampson Tuttle (Littleton, Mass.); and Henry Woods (Pepperell, Mass.).

Quaedam Theses extractae potissimii ex Enchiridio Metaphisico ca. 1718

Small paper notebook with a handwritten copy of a Latin text titled “Quaedam Theses extractae potissimii ex Enchiridio Metaphisico” attributed to John Clark and J. Remington and copied by a Harvard student, likely Richard Dana (Harvard AB 1718). The text is a précis of sections of Jean Le Clerc's "Ontologia et Pneumatologia" prepared by Harvard Tutor Jonathan Remington (Harvard AB 1696). The paper cover is inscribed “Carpenter” and the first page includes the inscriptions “Rosewell Saltonstall,” “Ezra Carpenter,” and "R. Dana” indicating the book was once owned by Harvard students Richard Dana (Harvard AB 1718), Roswell Saltonstall (Harvard AB 1720), and Ezra Carpenter (Harvard AB 1720).

Modulation allostérique du récepteur FP dans le cancer colorectal

Les prostaglandines modulent d’importants rôles physiologiques. Elles sont aussi impliquées dans le développement d’une variété de conditions pathologiques telles l’inflammation, la douleur et le cancer. La prostaglandine PGF2α et son récepteur (récepteur FP) se trouvent impliqué dans la modulation de nombreuses pathologies tels lors de l’accouchement préterme et le cancer colorectal. Récemment, nous avons fait partie d’un groupe de recherche ayant développé des modulateurs allostériques du récepteur FP. Dans une première étude, l’action du PGF2α sur le déclenchement des contractions myométriales a été évaluée, car peu d’information est connue sur la signalisation de cette prostaglandine lors de l’accouchement. Ainsi, nous avons utilisé un peptidomimétique de la deuxième boucle extracellulaire, dénommée PDC113.824. Nos résultats ont démontré que le PDC113.824 permettait de retarder la mise bas chez des souris gestantes, mais agissait de manière différente sur les multiples voies de signalisation de la PGF2α. Ainsi, le PDC113.824 inhibait la voie RhoA-ROCK, dépendante de l’activation de la protéine Gα12 par le. Les protéines RhoA-ROCK sont des acteurs clés dans le remodelage du cytosquelette d’actine et des contractions myométriales lors de l’accouchement. De plus, le PDC113.824 en présence de PGF2α agit comme un modulateur positif sur la voie dépendante de l’activation de la protéine Gαq. Le PDC113.824 serait donc un modulateur allostérique non compétitif possédant des actions à la fois de modulateurs positifs et négatifs sur la signalisation du récepteur FP Dans une seconde étude, des analogues du PDC113.824 ont été conçus et analysés dans un second modèle pathologique, le cancer colorectal. Ce cancer possède de hauts niveaux de récepteur FP. Nous avons donc étudié le rôle du récepteur FP dans le développement et la progression du cancer colorectal et l’effet de modulateurs allostériques. Il est généralement accepté que dans le cancer colorectal, la prostaglandine PGE2 permet la croissance et l’invasion tumorale, ainsi que l’angiogenèse. Toutefois, peu d’informations sont connues sur le rôle du PGF2α dans le cancer colorectal. C’est dans ce contexte que nous avons décidé d’examiner la contribution de ce récepteur dans la progression du cancer colorectal et cherché à déterminer si la modulation des fonctions du récepteur FP a un impact sur la croissance de tumeurs colorectales. Nos recherches ont révélé que l’activation du récepteur FP permet la migration et la prolifération de plusieurs lignées cellulaires humaines et murines d’adénocarcinomes colorectaux. Dans ce contexte, nos expériences ont démontré que la migration des cellules cancéreuses était dépendante de l’activation de la voie Rho. Nos résultats démontrent qu’en effet, l’activation de RhoA, une petite GTPase clé de la voie Gα12, est inhibée de façon sélective par nos composés. De plus, nos molécules allostériques sont également efficaces pour inhiber la voie de signalisation de la ß-caténine, une protéine impliquée dans la genèse du cancer colorectal. In vivo, le traitement de souris avec un des ces modulateurs a permis une inhibition effective de la croissance tumorale. Dans l’ensemble, nos résultats suggèrent donc que les modulateurs allostériques des récepteurs FP pourraient constituer une nouvelle classe de médicaments utilisés pour le traitement du cancer colorectal.

Annotated record of the detailed examination of Mn deposits from the R/V Galathea II Danish Deep Sea Expedition, 1950-1952

The Danish Expedition of the "Galathea II" around the world brought important results concerning the marine organisms in the deep sea. The "Galathea II" showed not only different organisms of the Abyssal but for the first time of the deepest trenches of the western Pacific. Anton Bruun coined the term Hadal for the region below the Abyssal under 6000 m. Although the "Galathea II" aimed to investigate new deep sea regions beside the routes of former expeditions and to widen the horizon of knowledge relating marine organisms the technical equipment and the methodological approach had partly been developed earlier. The expedition of the "Galathea II" is part of a long tradition of cruises such as that of the British "Challenger", the German "Valdivia" and the Swedish "Albatross" and especially the Danish cruises of the "Dana I" and "Dana II" which happened some years before.

Seed dispersal characteristics to polar regions by means of visitors

Invasive alien species are among the primary causes of biodiversity change globally, with the risks thereof broadly understood for most regions of the world. They are similarly thought to be among the most significant conservation threats to Antarctica, especially as climate change proceeds in the region. However, no comprehensive, continent-wide evaluation of the risks to Antarctica posed by such species has been undertaken. Here we do so by sampling, identifying, and mapping the vascular plant propagules carried by all categories of visitors to Antarctica during the International Polar Year's first season (2007-2008) and assessing propagule establishment likelihood based on their identity and origins and on spatial variation in Antarctica's climate. For an evaluation of the situation in 2100, we use modeled climates based on the Intergovernmental Panel on Climate Change's Special Report on Emissions Scenarios Scenario A1B [Nakicenovic N, Swart R, eds (2000) Special Report on Emissions Scenarios: A Special Report of Working Group III of the Intergovernmental Panel on Climate Change (Cambridge University Press, Cambridge, UK)]. Visitors carrying seeds average 9.5 seeds per person, although as vectors, scientists carry greater propagule loads than tourists. Annual tourist numbers (~33,054) are higher than those of scientists (~7,085), thus tempering these differences in propagule load. Alien species establishment is currently most likely for the Western Antarctic Peninsula. Recent founder populations of several alien species in this area corroborate these findings. With climate change, risks will grow in the Antarctic Peninsula, Ross Sea, and East Antarctic coastal regions. Our evidence-based assessment demonstrates which parts of Antarctica are at growing risk from alien species that may become invasive and provides the means to mitigate this threat now and into the future as the continent's climate changes.

(Tables 1,2) Viability of Poa trivialis seeds transported to Antarctica from different locations

Antarctic ecosystems are at risk from the introduction of invasive species. The first step in the process of invasion is the transportation of alien species to Antarctic in a viable state. However, the effect of long-distance human-mediated dispersal, over different time-scales, on propagule viability is not well known. We assessed the viability of Poa trivialis seeds transported to Antarctica from the UK, South Africa and Australia by ship or by ship and aircraft. Following transportation to the Antarctic Treaty area, no reduction in seed viability was found, despite journey times lasting up to 284 days and seeds experiencing temperatures as low as -1.5°C. This work confirms that human-mediated transport may overcome the dispersal barrier for some propagules, and highlights the need for effective pre-departure biosecurity measures.

Sediment temperatures of the Håkon Mosby mud volcano measured continuously with a short temperature lance (LOOME)

The short sediment temperature probe were deployed and recovered with the LOOME observatory in 2009 and 2010, respectively. In addition to temperature, the loggers also recorded bottom water pressure at a sampling interval of 20 minutes. Even though the data obtained from the short temperature probe was strongly disturbed by leakage through a corroded connector, the data shows clearly that the probe was pulled out of the sediment on October 26, 2009, presumably by advancing mud flows.

Fluid compositions and mineralogy of precipitates from Mid Atlantic Ridge hydrothermal vents at 4°48'S

The effect of volcanic activity on submarine hydrothermal systems has been well documented along fast- and intermediate-spreading centers but not from slow-spreading ridges. Indeed, volcanic eruptions are expected to be rare on slow-spreading axes. Here we report the presence of hydrothermal venting associated with extremely fresh lava flows at an elevated, apparently magmatically robust segment center on the slow-spreading southern Mid-Atlantic Ridge near 5°S. Three high-temperature vent fields have been recognized so far over a strike length of less than 2 km with two fields venting phase-separated, vapor-type fluids. Exit temperatures at one of the fields reach up to 407°C, at conditions of the critical point of seawater, the highest temperatures ever recorded from the seafloor. Fluid and vent field characteristics show a large variability between the vent fields, a variation that is not expected within such a limited area. We conclude from mineralogical investigations of hydrothermal precipitates that vent-fluid compositions have evolved recently from relatively oxidizing to more reducing conditions, a shift that could also be related to renewed magmatic activity in the area. Current high exit temperatures, reducing conditions, low silica contents, and high hydrogen contents in the fluids of two vent sites are consistent with a shallow magmatic source, probably related to a young volcanic eruption event nearby, in which basaltic magma is actively crystallizing. This is the first reported evidence for direct magmatic-hydrothermal interaction on a slow-spreading mid-ocean ridge.
