The Digital Public Library of America (DPLA) is a digital library that strives to serve the public through digital collections accumulated from a wide variety of partners. Our chosen topic for the DPLA exhibit project is Perspectives on the Vietnam War. The Vietnam War remains a controversial topic of national interest, making it a topic of depth and of many perspectives. Our goals with this exhibit were to gather different perspectives of the war through personal stories, the media, presidential administrations of the war, military personnel, and the general public, including famous figures. We strove to demonstrate the variety of perspectives on the Vietnam War through a variation of digital objects and content that will be engaging for users: both black and white and color photos, videos, and audio files. Furthermore, we wanted to ensure that our digital materials are of high quality, properly documented, and easy to search and find thus all of our objects are from DPLA and are from usable original sources. This poster will describe our processes for organizational, object selection, building our exhibit, attainment of our goals, and detailed steps of our overall operation. The poster will also include details about the minor issues and bumps that occurred while reaching our final product as well as the team members’ perspectives on the project as a whole including: problems, words to for the wise, and triumphs.

Genome-scale metabolic models are valuable tools in the metabolic engineering process, based on the ability of these models to integrate diverse sources of data to produce global predictions of organism behavior. At the most basic level, these models require only a genome sequence to construct, and once built, they may be used to predict essential genes, culture conditions, pathway utilization, and the modifications required to enhance a desired organism behavior. In this chapter, we address two key challenges associated with the reconstruction of metabolic models: (a) leveraging existing knowledge of microbiology, biochemistry, and available omics data to produce the best possible model; and (b) applying available tools and data to automate the reconstruction process. We consider these challenges as we progress through the model reconstruction process, beginning with genome assembly, and culminating in the integration of constraints to capture the impact of transcriptional regulation. We divide the reconstruction process into ten distinct steps: (1) genome assembly from sequenced reads; (2) automated structural and functional annotation; (3) phylogenetic tree-based curation of genome annotations; (4) assembly and standardization of biochemistry database; (5) genome-scale metabolic reconstruction; (6) generation of core metabolic model; (7) generation of biomass composition reaction; (8) completion of draft metabolic model; (9) curation of metabolic model; and (10) integration of regulatory constraints. Each of these ten steps is documented in detail.

Animal toxins are of interest to a wide range of scientists, due to their numerous applications in pharmacology, neurology, hematology, medicine, and drug research. This, and to a lesser extent the development of new performing tools in transcriptomics and proteomics, has led to an increase in toxin discovery. In this context, providing publicly available data on animal toxins has become essential. The UniProtKB/Swiss-Prot Tox-Prot program (http://www.uniprot.org/program/Toxins) plays a crucial role by providing such an access to venom protein sequences and functions from all venomous species. This program has up to now curated more than 5000 venom proteins to the high-quality standards of UniProtKB/Swiss-Prot (release 2012_02). Proteins targeted by these toxins are also available in the knowledgebase. This paper describes in details the type of information provided by UniProtKB/Swiss-Prot for toxins, as well as the structured format of the knowledgebase.

Résumé : Cette recherche doctorale analyse l'engagement des médecins français autour de l'éducation physique entre 1741 et 1888. Basé sur un travail prosopographique d'identification des médecins qui ont participé à l'élaboration de l'éducation physique, ce travail repose sur une mise en dialogue de leurs prises de position respectives. Pour réaliser cette enquête, nous avons compulsé un large corpus de sources primaires, composé des ouvrages consacrés à la gymnastique médicale mais aussi une très large portion de la production d'imprimés touchant à l'anatomie, l'hygiène, la thérapeutique, la physiologie, l'orthopédie, etc. Le corpus contient également des articles des principaux dictionnaires médicaux de la période et des principales revues médicales du XIXe siècle. Avec une approche critique de l'historiographie et à partir de ce corpus, nous avons travaillé dans le cadre de contextes définis pour saisir au plus près les logiques sociales et scientifiques amenant les médecins auprès de l'éducation physique. Trois conjonctures successives structurent l'engagement médical. Entre 1741 et 1817, la thèse retrace l'émergence d'un questionnement ; les années 1817-1847 constituent un « moment orthopédique » dans la formulation de la gymnastique ; et finalement entre 1847 et 1888, on observe une diversification des voies de légitimation médicale des exercices du corps. Ces trois moments de l'histoire des « discours gymniques médicaux » proposent un certain nombre de convergences : la prégnance de l'orthopédie, une certaine concentration autour de la santé des corps féminins, l'inclusion dans un « projet hygiéniste » ; mais aussi des divergences et des singularités : relatives à la progressive structuration en cours du champ médical, à l'implication progressive du politique (surtout après 1845/1850), aux transformations des pathologies/doctrines médicales « dominantes », ainsi qu'à l'importance plus ou moins forte de l'une ou l'autre des facettes de l'éducation physique (militaire, athlétique, « médicinale » ou pédagogique). Le processus est aussi celui de l'expérimentation de la curation de certaines pathologies (scolioses, affections nerveuses), dans des configurations idéologiques/scientifiques marquées par la « dégénération » (XVIIIe siècle), l'anatomie pathologique (début du XIXe siècle) et plus tard la « dégénérescence » et les affections nerveuses (après 1850). Dans le cadre d'une dynamique d'inspiration « foucaldienne », ces recommandations évoluent d'une anatomopolitique - caractérisée par un essor de discours empreints d'anatomie au XVIIIe siècle - vers une biopolitique - caractérisée par l'engagement de l'Etat qui fait de la gymnastique une discipline d'enseignement, pensée à des fins hygiéniques dans la seconde moitié du XIXe - où le processus réside en fait dans une biologisation progressive des recommandations pratiques. Observée à l'aune de la formulation médicale de l'éducation physique, la biopolitique n'est pas réalisée dans la seconde moitié du XVIIIe, elle se compose lentement aux marges de l'institution scolaire et des gymnastiques pédagogico-militaires pour constituer un projet thérapeutique et hygiénique plus construit après 1850. Abstract : This dissertation analyzes French doctor's involvement in debates and initiatives concerning physical education between 1741 and 1888. Based on a prosopographic inventory of those physicians who participated in the development of physical education, it explores the variety of their discourses with respect to the practice of physical exercises. This investigation relies on a large selection of primary sources: works devoted to medical gymnastic, but also medical treatises related to anatomy, hygiene, therapeutics, physiology, orthopedics, etc. The sources also include articles from the major medical dictionaries and journals of the nineteenth century. These documents are used to explore the socio-scientific mechanisms that underlay physicians' commitment to physical education. Three chronological periods structure medical engagement in the area of physical education. Between 1741 and 1817 the thesis traces the emergence of a questioning; the years 1817 to 1847 represent an « orthopedic moment » in the development of gymnastics; finally between 1847 and 1888, one witnesses a diversification of the legitimation process between medicine and gymnastics. These three moments in the history of « medical and gymnastic discourses » offer a number of similarities: the weight of orthopedics, the ongoing focus on the health of the female body, and the association of these discourses with a « hygienic project ». But differences also distinguish these periods as the medical field became more structured and new medical doctrines became dominant, with the increasing involvement of politics (especially after 1850), and with the changing weight of priorities within physical education (military, athletic, « medical » or pedagogic). Medical discourses centered on the curing of certain diseases (scoliosis or nervous disorders) are analyzed within an ideological configuration marked by the idea of « degeneration » (in the eighteenth century), « pathological anatomy » (in the early nineteenth century) and later « dégénérescence » associated with nervous disorders (after 1850). The dissertation draws on Foucault's historical epistemology to understand how medical recommendations evolve from an anatomopolitics - characterized by a surge in anatomical discourses - toward a biopolitics - characterized by the commitment of the State to introduce gymnastics for hygienic purposes into schools in the second half of the nineteenth century. This process reveals a progressive "biologization" of practical recommendations. The medical discourses about physical education show that Foucault's biopolitical power is not achieved in the second half of the eighteenth century, but develops slowly at the margins of the school system and of pedagogical and military gymnastic, becoming a veritable hygienic and therapeutic project only after 1850.

The manipulation of DNA is routine practice in botanical research and has made a huge impact on plant breeding, biotechnology and biodiversity evaluation. DNA is easy to extract from most plant tissues and can be stored for long periods in DNA banks. Curation methods are well developed for other botanical resources such as herbaria, seed banks and botanic gardens, but procedures for the establishment and maintenance of DNA banks have not been well documented. This paper reviews the curation of DNA banks for the characterisation and utilisation of biodiversity and provides guidelines for DNA bank management. It surveys existing DNA banks and outlines their operation. It includes a review of plant DNA collection, preservation, isolation, storage, database management and exchange procedures. We stress that DNA banks require full integration with existing collections such as botanic gardens, herbaria and seed banks, and information retrieval systems that link such facilities, bioinformatic resources and other DNA banks. They also require efficient and well-regulated sample exchange procedures. Only with appropriate curation will maximum utilisation of DNA collections be achieved.

Genome-scale metabolic network reconstructions are now routinely used in the study of metabolic pathways, their evolution and design. The development of such reconstructions involves the integration of information on reactions and metabolites from the scientific literature as well as public databases and existing genome-scale metabolic models. The reconciliation of discrepancies between data from these sources generally requires significant manual curation, which constitutes a major obstacle in efforts to develop and apply genome-scale metabolic network reconstructions. In this work, we discuss some of the major difficulties encountered in the mapping and reconciliation of metabolic resources and review three recent initiatives that aim to accelerate this process, namely BKM-react, MetRxn and MNXref (presented in this article). Each of these resources provides a pre-compiled reconciliation of many of the most commonly used metabolic resources. By reducing the time required for manual curation of metabolite and reaction discrepancies, these resources aim to accelerate the development and application of high-quality genome-scale metabolic network reconstructions and models.

The Gene Ontology (GO) (http://www.geneontology.org) is a community bioinformatics resource that represents gene product function through the use of structured, controlled vocabularies. The number of GO annotations of gene products has increased due to curation efforts among GO Consortium (GOC) groups, including focused literature-based annotation and ortholog-based functional inference. The GO ontologies continue to expand and improve as a result of targeted ontology development, including the introduction of computable logical definitions and development of new tools for the streamlined addition of terms to the ontology. The GOC continues to support its user community through the use of e-mail lists, social media and web-based resources.

BACKGROUND: The nuclear receptors are a large family of eukaryotic transcription factors that constitute major pharmacological targets. They exert their combinatorial control through homotypic heterodimerisation. Elucidation of this dimerisation network is vital in order to understand the complex dynamics and potential cross-talk involved. RESULTS: Phylogeny, protein-protein interactions, protein-DNA interactions and gene expression data have been integrated to provide a comprehensive and up-to-date description of the topology and properties of the nuclear receptor interaction network in humans. We discriminate between DNA-binding and non-DNA-binding dimers, and provide a comprehensive interaction map, that identifies potential cross-talk between the various pathways of nuclear receptors. CONCLUSION: We infer that the topology of this network is hub-based, and much more connected than previously thought. The hub-based topology of the network and the wide tissue expression pattern of NRs create a highly competitive environment for the common heterodimerising partners. Furthermore, a significant number of negative feedback loops is present, with the hub protein SHP [NR0B2] playing a major role. We also compare the evolution, topology and properties of the nuclear receptor network with the hub-based dimerisation network of the bHLH transcription factors in order to identify both unique themes and ubiquitous properties in gene regulation. In terms of methodology, we conclude that such a comprehensive picture can only be assembled by semi-automated text-mining, manual curation and integration of data from various sources.

The GO annotation dataset provided by the UniProt Consortium (GOA: http://www.ebi.ac.uk/GOA) is a comprehensive set of evidenced-based associations between terms from the Gene Ontology resource and UniProtKB proteins. Currently supplying over 100 million annotations to 11 million proteins in more than 360,000 taxa, this resource has increased 2-fold over the last 2 years and has benefited from a wealth of checks to improve annotation correctness and consistency as well as now supplying a greater information content enabled by GO Consortium annotation format developments. Detailed, manual GO annotations obtained from the curation of peer-reviewed papers are directly contributed by all UniProt curators and supplemented with manual and electronic annotations from 36 model organism and domain-focused scientific resources. The inclusion of high-quality, automatic annotation predictions ensures the UniProt GO annotation dataset supplies functional information to a wide range of proteins, including those from poorly characterized, non-model organism species. UniProt GO annotations are freely available in a range of formats accessible by both file downloads and web-based views. In addition, the introduction of a new, normalized file format in 2010 has made for easier handling of the complete UniProt-GOA data set.
