Building a Canadian Virtual Health Library Database / Création de la Bibliothèque virtuelle canadienne de santé

Introduction: Avec l’abondance d’information gratuite disponible en ligne, la tâche de trouver, de trier et d’acheminer de l’information pertinente à l’auditoire approprié peut s’avérer laborieuse. En décembre 2010, la Bibliothèque virtuelle canadienne de santé / Canadian Virtual Health Library (BVCS) a formé un comité d’experts afin d’identifier, d’évaluer, de sélectionner et d’organiser des ressources d’intérêt pour les professionnels de la santé. Méthodes: Cette affiche identifiera les décisions techniques du comité d’experts, incluant le système de gestion de contenus retenu, l’utilisation des éléments Dublin Core et des descripteurs Medical Subject Headings pour la description des ressources, et le développement et l’adaptation de taxonomies à partir de la classification MeSH. La traduction française des descripteurs MeSH à l’aide du portail CISMeF sera également abordée. Résultats: Au mois de mai 2011, le comité a lancé la base de données BVCS de ressources en ligne gratuites sur la santé, regroupant plus de 1600 sites web et ressources. Une variété de types de contenus sont représentés, incluant des articles et rapports, des bases de données interactives et des outils de pratique clinique. Discussion: Les bénéfices et défis d’une collaboration pancanadienne virtuelle seront présentés, ainsi que l’inclusion cruciale d’un membre francophone pour composer avec la nature bilingue de la base de données. En lien avec cet aspect du projet, l’affiche sera présentée en français et en anglais. Introduction: With the abundance of freely available online information, the task of finding, filtering and fitting relevant information to the appropriate audience, is daunting. In December 2010 the Canadian Virtual Health Library / Bibliothèque virtuelle canadienne de santé (CVHL) formed an expert committee to identify, evaluate, select and organize resources relevant to health professionals. Methods: This poster will identify the key technical decisions of the expert committee including the content management system used to manage the data, the use of Dublin Core elements and Medical Subject Headings to describe the resources, and the development and adaptation of taxonomies from MeSH classification to catalog resources. The translation of MeSH terms to French using the CiSMeF portal will also be discussed. Results: In May 2010, the committee launched the CVHL database of free web-based health resources. Content ranged from online articles and reports to videos, interactive databases and clinical practice tools, and included more than 1,600 websites and resources. Discussion: The benefits and challenges of a virtual, pan-Canadian collaboration, and the critical inclusion of a Francophone member to address the bilingual nature of the database, will be presented. In keeping with the nature of the project, the poster will be presented in French and English.

A portal for the Canadian Virtual Health Library / Bibliothèque virtuelle canadienne de la santé (CVHL/BVCS): Accomplishments and possibilities, scope and structure - a review of best practices

Introduction: Coordination through CVHL/BVCS gives Canadian health libraries access to information technology they could not offer individually, thereby enhancing the library services offered to Canadian health professionals. An example is the portal being developed. Portal best practices are of increasing interest (usability.gov; Wikipedia portals; JISC subject portal project; Stanford clinical portals) but conclusive research is not yet available. This paper will identify best practices for a portal bringing together knowledge for Canadian health professionals supported through a network of libraries. Description: The portal for Canadian health professionals will include capabilities such as: • Authentication • Question referral • Specialist “branch libraries” • Integration of commercial resources, web resources and health systems data • Cross-resource search engine • Infrastructure to enable links from EHR and decision support systems • Knowledge translation tools, such as highlighting of best evidence Best practices will be determined by studying the capabilities of existing portals, including consortia/networks and individual institutions, and through a literature review. Outcomes: Best practices in portals will be reviewed. The collaboratively developed Virtual Library, currently the heart of cvhl.ca, is a unique database collecting high quality, free web documents and sites relevant to Canadian health care. The evident strengths of the Virtual Library will be discussed in light of best practices. Discussion: Identification of best practices will support cost-benefit analysis of options and provide direction for CVHL/BVCS. Open discussion with stakeholders (libraries and professionals) informed by this review will lead to adoption of the best technical solutions supporting Canadian health libraries and their users.

Antigen and superantigen presentation as defined by the MHCII-accessory proteins and associated-peptides

MHCII molecules expose a weave of antigens, which send survival or activation signals to T lymphocytes. The ongoing process of peptide binding to the MHC class II groove implicates three accessory molecules: the invariant chain, DM and DO. The invariant chain folds and directs the MHCII molecules to the endosomal pathway. Then, DM exchanges the CLIP peptide, which is a remnant of the degraded invariant chain, for peptides of better affinity. Expressed in highly specialized antigen presenting cells, DO competes with MHCII molecules for DM binding and favors the presentation of receptor-internalized antigens. Altogether, these molecules exhibit potential immunomodulatory properties that can be exploited to increase the potency of peptide vaccines. DO requires DM for maturation and to exit the ER. Interestingly, it is possible to monitor this interaction through a conformation change on DOβ that is recognized by the Mags.DO5 monoclonal antibody. Using Mags.DO5, we showed that DM stabilizes the interactions between the DO α1 and β1 chains and that DM influences DO folding in the ER. Thus, the Mags.DO5+ conformation correlates with DO egress from the ER. To further evaluate this conformation change, directed evolution was applied to DO. Of the 41 unique mutants obtained, 25% were localized at the DM-DO binding interface and 12% are at the solvent-exposed β1 domain, which is thought to be the Mags.DO5 epitope. In addition, I used the library to test the ability of HLA-DO to inhibit HLA-DM and sorted for the amount of CLIP. Interestingly, most of the mutants showed a decrease inhibitory effect, supporting the notion that the intrinsic instability of DO is a required for its function. Finally, these results support the model in which DO competes against classical MHCII molecules by sequestering DM chaperone’s function. MHCII molecules are also characterized by their ability to present superantigens, a group of bacterial or viral toxins that coerces MHCII-TCR binding in a less promiscuous fashion than what is observed in a canonical setting. While the mechanism of how bacterial superantigens form trimeric complexes with TCR and MHCII is well understood, the mouse mammary tumor virus superantigens (vSAG) are poorly defined. In the absence of a crystal structure, I chose a functional approach to examine the relation between vSAG, MHCII and TCR with the goal of uncovering the overall trimolecular architecture. I showed that TCR concomitantly binds both the MHCII α chain and the vSAG and that TCR-MHCII docking is almost canonical when coerced by vSAGs. Because many peptides may be tolerated in the MHCII groove, the pressure exerted by vSAG seems to tweak conventional TCR-MHCII interactions. Furthermore, my results demonstrate that vSAG binding to MHCII molecules is conformation-dependent and abrogated by the CLIP amino-terminal residues extending outside the peptide-binding groove. In addition, they also suggest that vSAGs cross-link adjacent MHCIIs and activate T cells via a TGXY motif.

Graphic medicine from library to classroom

Introduction. Graphic medicine is defined as the use of comics in health sciences education and patient care. Graphic stories about personal experiences of illness from patients and their families can be used to illustrate distress, empathy and collaboration between family members and health professionals and thus give students a broader experience of disease. We present a collection of graphic novels and outline collaboration with professors from various faculties in order to use comics as teaching material in health sciences. Method. The university has health sciences faculties of Nursing, Medicine, Pharmacy, Dentistry, Veterinary Medicine and schools of Public Health, Optometry and Kinesiology. The Health Library is offering its patrons a collection of 40 comics mainly on the theme of patient and family illness experience. An ongoing survey gathers feedback from users; results will help us promote the collection. A librarian is working with professors from the facultiesof Nursing, Medicine and Pharmacy in order to integrate comics’ excerpts into e-learning modules for three health and social services interprofessional courses reaching more than 1000 students annually. Other courses teaching empathy and partnership with patients will be identified and professors will be approached to raise awareness of the collection’s potential as teaching material. Results. The collection has been available to patrons since October 2012. Survey responses collected so far are very positive and titles are regularly borrowed. The collection has been added as suggested reading in a physiotherapy course outline. Discussion. The comics’ collection is already widely used by our patrons. Steps are being taken to integrate the collection into more health sciences courses and thus define graphic medicine as teaching material in health sciences education at the university.

Use of cellular impedance to characterize ligand functional selectivity at G protein-coupled receptors

Les récepteurs couplés aux protéines G (RCPGs) représentent la plus grande famille de cibles thérapeutiques pour le traitement d’une panoplie de pathologies humaines. Bien que plusieurs décennies de recherche aient permis de façonner nos connaissances sur ces protéines membranaires, notre compréhension des déterminants moléculaires de leur activité signalétique reste encore limitée. De ces domaines de recherche, une avancée récente a mis à jour un nouveau phénomène, appelé sélectivité fonctionnelle des ligands, qui a bouleversé les paradigmes décrivant leu fonctionnement de ces récepteurs. Ce concept émane d’observations montrant que l’activité pharmacologique de certains ligands n’est pas nécessairement conservée sur tout le répertoire signalétiques connu du récepteur et peu se restreindre à l'activation sélective d’un sous-groupe de voies de signalisation.Ce nouveau modèle pharmacologique de l'activation des RCPG ouvre de nouvelles possibilités pour la découverte de médicaments plus efficace et sûr, ciblant les RCPGs. En effet, il permet la conception de molécules modulant spécifiquement les voies signalétiques d’intérêt thérapeutique, sans engager les autres voies qui pourraient mener à des effets secondaires indésirables ou de la tolérance. Cette thèse décrit l'utilisation d'une nouvelle approche sans marquage, basée sur la mesure du changement l'impédance cellulaire. Par la mesure des changements cellulaires, comme la morphologie, l’adhésion et/ou la redistribution des macromolécules, cette approche permet de mesurer de façon simultanée l'activité de plusieurs voies de signalisation impliqués dans ces réponses. Utilisant le récepteur β2-adrénergique (β2AR) comme modèle, nous avons démontré que les variations dans l’impédance cellulaire étaient directement liées à l’activation de multiples voies de signalisation suite à la stimulation du récepteur par son ligand. L’agoniste type du β2AR, l’isoprotérénol, s’est avéré induire une réponse d’impédance dose-dépendante constituée, dans le temps, de plusieurs caractéristiques distinctes pouvant être bloquées de façon compétitive par l’antagoniste ICI118,551 Par l’utilisation d’inhibiteurs sélectifs, nous avons été en mesure de déterminer la contribution de plusieurs voies signalétiques canoniques, comme les voies dépendantes de Gs et Gi, la production d’AMPc et l’activation de ERK1/2, sur ces changements. De plus, la dissection de la réponse d’impédance a permis d’identifier une nouvelle voie de mobilisation du Ca2+ contribuant à la réponse globale des changements initiés par la stimulation du β2AR. Dans une autre étude, nous avons rapporté que la réponse calcique induite par le β2AR serait attribuable à une transactivation Gs-dépendant du récepteur purinergique P2Y11, lui-même couplé à la protéine Gq. La mesure d’impédance permettant de distinguer et de décrire une pléiade d’activités signalétiques, nous avons émis l’hypothèse que des ligands arborant des profils signalétiques différents généreraient des réponses d’impédance distinctes. Le criblage d’une librairie de ligands spécifiques au β2AR a révélé une grande variété de signatures d’impédance. Grâce au développement d’une approche computationnelle innovatrice, nous avons été en mesure de regrouper ces signatures en cinq classes de composés, un regroupement qui s’est avéré hautement corrélé avec le profil signalétique des différents ligands. Nous avons ensuite combiné le criblage de composés par impédance avec l’utilisation d’inhibiteurs sélectifs de voies signalétiques afin d’augmenter la résolution du regroupement. En évaluant l’impact d’une voie signalétique donnée sur la signature d’impédance, nous avons été en mesure de révéler une plus grande variété de textures parmi les ligands. De plus, cette méthode s’est avérée efficace pour prédire le profil signalétique d’une librairie de composés non caractérisés, ciblant le β2AR. Ces travaux ont mené à l’élaboration d’une méthode permettant d’exprimer visuellement la sélectivité fonctionnelle de ligands et ont révélé de nouvelles classes de composés pour ce récepteur. Ces nouvelles classes de composés ont ensuite été testées sur des cardiomyocytes humains, confirmant que les composés regroupés dans différentes classes produisent des effets distincts sur la contractilité de ces cellules. Globalement, ces travaux démontrent la pertinence de l’utilisation de l’impédance cellulaire pour une évaluation précise des différences fonctionnelles parmi les composés ciblant les RCPGs. En fournissant une représentation pluridimensionnelle de la signalisation émanant des RCPGs à l’aide d’un seul essai ne requérant pas de marquage, les signatures d’impédance représentent une stratégie simple et innovante pour l’évaluation de la fonctionnalité sélective des ligands. Cette méthode pourrait être d’une grande utilité dans le processus de découverte de nouveaux médicaments.

An Evaluation of Extension Activities in the Development of Aquaculture in Kerala

Aquaculture is one of the prime catalysts for the socio-economic development of Indian economy contributing to the nations food and nutritional security, export earnings, income and employment generation. In this study an evaluation of extension activities in the development of aquaculture in Kerala. This study was conducted with a view to examine how the Kerala fisheries department offered extension services to the aquaculture farmers in the freshwater and brackish water sectors of the state through various agencies like Fish Farmers Development Agency(FFDA), Brackish water Fish Farmers Development Agency (BFFDA). In this study there are 3 category of respondent’s fresh water beneficiary farmers, brackish water beneficiary farmers and fisheries extension officers. The main motive of the thesis is to make an attempt to explore the responses of local producers to the extension programs of the state with special reference to the aquaculture sector of Kerala, India. The most important technical constraint faced by the fresh water farmers was lack of knowledge followed by non-availability of quality seeds. In the case of brackish water farming, it was infection of disease followed by lack of knowledge. The overall activities of the department of fisheries were ‘fairly good’. It indicate the need for improvements in the delivery of extension services to various target groups. The state fisheries department has already moving towards evolving these modes of extension activities by community participation.

Impact of Information Communication Technology (ICT) on Professional Development and Educational Needs of Library Professionals in the Universities of Kerala

The shift from print to digital information has a high impact on all components of the academic library system in India especially the users, services and the staff. Though information is considered as an important resource, the use of ICT tools to collect and disseminate information has been in a slow pace in majority of the University libraries This may be due to various factors like insufficient funds, inadequate staff trained in handling computers and software packages, administrative concerns etc. In Kerala, automation has been initiated in almost all University libraries using library automation software and is under different stages of completion. There are not much studies conducted about the effects of information communication technologies on the professional activities of library professionals in the universities in Kerala. It is important to evaluate whether progress in ICT has had any impact on the library profession in these highest educational institutions. The aim of the study is to assess whether the developments in information communication technologies have any influence on the library professionals’ professional development, and the need for further education and training in the profession and evaluate their skills in handling developments in ICT. The total population of the study is 252 including the permanently employed professional library staff in central libraries and departmental libraries in the main campuses of the universities under study. This is almost a census study of the defined population of users. The questionnaire method was adopted for collection of data for this study, supplemented by interviews of Librarians to gather additional information. Library Professionals have a positive approach towards ICT applications and services in Libraries, but majority do not have the opportunities to develop their skills and competencies in their work environment. To develop competitive personnel in a technologically advanced world, high priority must be given to develop competence in ICT applications, library management and soft skills in library professionals, by the University administrators and Library associations. Library science schools and teaching departments across the country have to take significant steps to revise library science curriculum, and incorporate significant changes to achieve the demands and challenges of library science profession.

A study of the information seeking bebavior of science and technology teachers and researchers of Cocbin University of Science and Technology and University of Kerala in the cbanged library environment

Information communication technology (IC T) has invariably brought about fundamental changes in the way in which libraries gather. preserve and disseminate information. The study was carried out with an aim to estimate and compare the information seeking behaviour (ISB) of the academics of two prominent universities of Kerala in the context of advancements achieved through ICT. The study was motivated by the fast changing scenario of libraries with the proliferation of many high tech products and services. The main purpose of the study was to identify the chief source of information of the academics, and also to examine academics preference upon the form and format of information source. The study also tries to estimate the adequacy of the resources and services currently provided by the libraries.The questionnaire was the central instrument for data collection. An almost census method was adopted for data collection engaging various methods and tools for eliciting data.The total population of the study was 957, out of which questionnaire was distributed to 859 academics. 646 academics responded to the survey, of which 564 of them were sound responses. Data was coded and analysed using Statistical Package for Social Sciences (SPSS) software and also with the help of Microsofl Excel package. Various statistical techniques were engaged to analyse data. A paradigm shift is evident by the fact that academies push themselves towards information in internet i.e. they prefer electronic source to traditional source and the very shift is coupled itself with e-seeking of information. The study reveals that ISB of the academics is influenced priman'ly by personal factors and comparative analysis shows that the ISB ofthc academics is similar in both universities. The productivity of the academics was tested to dig up any relation with respect to their ISB, and it is found that productivity of the academics is extensively related with their ISB. Study also reveals that the users ofthe library are satisfied with the services provided but not with the sources and in conjunction, study also recommends ways and means to improve the existing library system.

Marketing of Library Services in an Academic Environment

Marketing of information services is now an important goal of librarians all over the ~orld t? attract mor~ users to the libr~ry. thereby promoting user satisfaction. Marketing IS considered ~s ~n Integr~1 part of libraries and information centres mainly due to the developments In information t.echnology, information explosion, and declining library budgets. Kotler defines marketing as the "analysis, planning, implementation and control o~ carefully formulated programs designed to bring about voluntary exchanges of values WIth target markets fo~ the ~~rpos~ of~chievingorganizational objectives". Organizations suc.h as museums, unrversittes, libraries, and charities need to market their causes and their products to gain. political and social support as well as economic support (Kotler, 1995). In the marketing world people are now migrating from the traditional Four P ~lodelto th~ S~VE mode! (Alt~ns~n, 2013). According to the SAVE model, marketing III an orgarusanon must grve pnonty to 'Solutions' instead of the features or functions of~he.'Product" Similarily it is to focus on 'Access', instead of ,Place'; 'Value' instead of Price" so that the benefits are more stressed, rather than production costs. Instead of :Proliloti.on', marketi~g has. to conc~ntrate on 'Educating' the customers, providing lJlfo~mahol~ about t~eJr specific req~lrements, instead of relying on advertising, public rel~tlons, direct selling etc. From a library point ofview, to ensure maximum utilization of library ~ervices there is an increasing need for definite marketing plans to exploit the techn.ologlcal dcvelop",len~s so ~s to entice the users. By anticipating their changing needs and ~y co.mmulllcatl~g WIth them it should be possible to devise strategies to present various library services and products in a perceptive style.

Extension schemes for the Alignment Model of English-Malayalam Statistical Machine Translator

In Statistical Machine Translation from English to Malayalam, an unseen English sentence is translated into its equivalent Malayalam sentence using statistical models. A parallel corpus of English-Malayalam is used in the training phase. Word to word alignments has to be set among the sentence pairs of the source and target language before subjecting them for training. This paper deals with certain techniques which can be adopted for improving the alignment model of SMT. Methods to incorporate the parts of speech information into the bilingual corpus has resulted in eliminating many of the insignificant alignments. Also identifying the name entities and cognates present in the sentence pairs has proved to be advantageous while setting up the alignments. Presence of Malayalam words with predictable translations has also contributed in reducing the insignificant alignments. Moreover, reduction of the unwanted alignments has brought in better training results. Experiments conducted on a sample corpus have generated reasonably good Malayalam translations and the results are verified with F measure, BLEU and WER evaluation metrics.

Impact of ICT on Library and Information Science: Major Shifts and Practices in CUSAT Central Library

Information is knowledge, facts or data. For the purpose of enabling the users to assimilate information, it should be repacked. Knowledge becomes information when it is externalized i.e. put in to the process of communication. The effectiveness of communication technology depends how well it provides its clients with information rapidly, economically and authentically. A large number of ICT enabled services including OPAC; e-resources etc. are available in the university library. Studies have been done to find the impact of ICT on different sections of CUSAT library by observing the activities of different sections; discussions with colleagues and visitors; and analyzing the entries in the library records. The results of the studies are presented here in the form of a paper.
