Kinetics of chronic inflammation in Nile tilapia fed n‑3 and n‑6 essential fatty acids

The objective of this work was to investigate the effect of dietary supplementation with essential fatty acids on the kinetics of macrophage accumulation and giant cell formation in Nile tilapia (Oreochromis niloticus). The supplementation sources were soybean oil (SO, source of omega 6, n‑6) and linseed oil (LO, source of omega 3, n‑3), in the following proportions: 100% SO; 75% SO + 25% LO; 50% SO + 50% LO; 25% SO + 75% LO; and 100% LO (four replicates per treatment). After a feeding period of three months, growth performance was evaluated, and glass coverslips were implanted into the subcutaneous connective tissue of fish, being removed for examination at 2, 4, 6, and 8 days after implantation. Growth performance did not differ between treatments. Fish fed 100% linseed oil diet had the greatest macrophage accumulation and the fastest Langhans cell formation on the sixth day. On the eighth day, Langhans cells were predominant on the coverslips implanted in the fish feed 75 and 100% linseed oil. n‑3 fatty acids may contribute to macrophage recruitment and giant cell formation in fish chronic inflammatory response to foreign body.

Repurposing Social Tagging Data for Extraction of Domain-level Concepts

The World Wide Web, the world¿s largest resource for information, has evolved from organizing information using controlled, top-down taxonomies to a bottom up approach that emphasizes assigning meaning to data via mechanisms such as the Social Web (Web 2.0). Tagging adds meta-data, (weak semantics) to the content available on the web. This research investigates the potential for repurposing this layer of meta-data. We propose a multi-phase approach that exploits user-defined tags to identify and extract domain-level concepts. We operationalize this approach and assess its feasibility by application to a publicly available tag repository. The paper describes insights gained from implementing and applying the heuristics contained in the approach, as well as challenges and implications of repurposing tags for extraction of domain-level concepts.

Essential PchG-dependent reduction in pyochelin biosynthesis of Pseudomonas aeruginosa.

The biosynthetic genes pchDCBA and pchEF, which are known to be required for the formation of the siderophore pyochelin and its precursors salicylate and dihydroaeruginoate (Dha), are clustered with the pchR regulatory gene on the chromosome of Pseudomonas aeruginosa. The 4.6-kb region located downstream of the pchEF genes was found to contain three additional, contiguous genes, pchG, pchH, and pchI, probably forming a pchEFGHI operon. The deduced amino acid sequences of PchH and PchI are similar to those of ATP binding cassette transport proteins with an export function. PchG is a homolog of the Yersinia pestis and Y. enterocolitica proteins YbtU and Irp3, which are involved in the biosynthesis of yersiniabactin. A null mutation in pchG abolished pyochelin formation, whereas mutations in pchH and pchI did not affect the amounts of salicylate, Dha, and pyochelin produced. The pyochelin biosynthetic genes were expressed from a vector promoter, uncoupling them from Fur-mediated repression by iron and PchR-dependent induction by pyochelin. In a P. aeruginosa mutant lacking the entire pyochelin biosynthetic gene cluster, the expressed pchDCBA and pchEFG genes were sufficient for salicylate, Dha, and pyochelin production. Pyochelin formation was also obtained in the heterologous host Escherichia coli expressing pchDCBA and pchEFG together with the E. coli entD gene, which provides a phosphopantetheinyl transferase necessary for PchE and PchF activation. The PchG protein was purified and used in combination with PchD and phosphopantetheinylated PchE and PchF in vitro to produce pyochelin from salicylate, L-cysteine, ATP, NADPH, and S-adenosylmethionine. Based on this assay, a reductase function was attributed to PchG. In summary, this study completes the identification of the biosynthetic genes required for pyochelin formation from chorismate in P. aeruginosa.

Genetic polymorphism of CCR5 gene and HIV disease: the heterozygous (CCR5/delta ccr5) genotype is neither essential nor sufficient for protection against disease progression. Swiss HIV Cohort.

Homozygous (delta ccr5/delta ccr5) and heterozygous (CCR5/delta ccr5) deletions in the beta-chemokine receptor 5 (CCR5) gene, which encodes for the major co-receptor for macrophage-tropic HIV-1 entry, have been implicated in resistance to HIV infection and in protection against disease progression, respectively. The CCR5/delta ccr5 genotype was found more frequently in long-term nonprogressors (LTNP) (31.0%) than in progressors (10.6%, p < 0.0001), in agreement with previous studies. Kaplan-Meier survival analyses showed that a slower progression of disease, i.e. higher proportion of subjects with CD4+ T cell counts > 500/microl (p = 0.0006) and a trend toward a slower progression to AIDS (p = 0.077), was associated with the CCR5/delta ccr5 genotype. However, when LTNP were analyzed separately, no significant differences in CD4+ T cell counts (p = 0.12) and viremia levels (p = 0.65) were observed between the wild-type (69% of LTNP) and the heterozygous (31.0%) genotypes. Therefore, there are other factors which play a major role in determining the status of nonprogression in the majority of LTNP. Furthermore, there was no evidence that the CCR5/delta ccr5 genotype was associated with different rates of disease progression in the group of progressors. Taken together, these results indicate that the CCR5/delta ccr5 genotype is neither essential nor sufficient for protection against the progression of HIV disease.

Kiinteistön investointi- ja elinkaarikustannusten hallinnan työkalut

Tämän työntavoitteena oli tutkia kiinteistöjen investointi- ja elinkaarikustannusten hallinnan tilannetta. Tavoitteeseen pääsemiseksi pyrin selvittämään, missä määrin rakennusala käyttää erilaisia ohjelmistoja, mitä nämä ohjelmistot ovat ja minkälaiset ovat mahdollisuudet kehittää tähän tarkoitukseen sopiva ohjelmistotyökalu. Teoriaosa koostuu kiinteistöliiketoimintaan liittyvistä peruskäsitteistäsekä laskentamenetelmistä. Empiirisessä osassa esitellään tutkimusmenetelmät jaanalysoidaan tulokset. Tutkimus toteutettiin käyttämällä kirjallista kyselyä sekä asiantuntijahaastatteluita. Kirjallinen kysely toimi runkona haastatteluille. Kyselyllä kartoitettiin olemassa olevien ohjelmistotyökalujen lukumäärä. Haastattelujen avulla pyrittiin saamaan selville, mitkä ohjelmistojen osiot ja ominaisuudet olisivat käyttäjän kannalta olennaisia. Tutkimuksen tärkeimpänä tuloksena voidaan pitää sitä, että olemassa olevien työkalujen lisäksi ei näyttänyt olevan juurikaan tarvetta kehittää uusia työkaluja kiinteistökustannusten hallintaan. Ohjelmistotyökaluja löydettiin kolmetoista, joista kaksitoista soveltui elinkaarikustannusten laskentaan. Sellaisia ohjelmatyökaluja, jotka olisivat vastanneet asiantuntijahaastateltavien tarpeita, ei löytynyt. Tutkimustulokset osoittavat kuitenkin selvästi, että kehitysmahdollisuudet ovat olemassa ja ongelmaon helposti ratkaistavissa yhdistelemällä eri ohjelmistojen ominaisuuksia.

Therapeutic concepts in adult and paediatric eosinophilic oesophagitis.

Eosinophilic oesophagitis (EoE) was first described in the early 1990s. Although initially reported to be a rare entity, EoE has rapidly become a regularly diagnosed disease with a prevalence of approximately 1 in 2,000 individuals in the USA and Europe. The disease is characterized by a combination of oesophageal dysfunction and predominant eosinophilic infiltration of the oesophageal tissue. At diagnosis, other diseases that can be associated with oesophageal eosinophilic infiltration must be ruled out. Children with EoE present with a wide variety of symptoms, whereas adults mostly present with dysphagia for solid food and chest pain. Histologic features of EoE resemble those of T-helper type 2 inflammation. Endoscopy should be carried out to establish the diagnosis, but endoscopic abnormalities are not pathognomonic for EoE and the examination might not show histologic abnormality. Treatment modalities for EoE include drugs (corticosteroids, PPIs, antiallergic and biologic agents), hypoallergenic diets and oesophageal dilatation for strictures that are unresponsive to medical therapy. Unresolved eosinophilic inflammation leads to the formation of oesophageal strictures, which probably increase the risk of food bolus impactions. To date, long-term strategies for the therapeutic management of this chronic inflammatory disease remain poorly defined.

Hankintaprosessin suorituskyvyn mittaaminen

Tutkimuksen päätavoite oli kehittää teollisuusyrityksen hankintaprosessille kattavat suorituskykymittarit ja sillä pyrittiin vastaamaan kysymykseenMiten ERP -järjestelmän käyttäminen informaation lähteenä vaikuttaa hankintaprosessin suorituskyvyn mittaamiseen? Teoriaosassa paneuduttiin suorituskyvyn mittaamisen, hankintaprosessin suorituskyvyn mittaamisen sekä ERP -järjestelmän käsitteisiin ja keskeisiin ilmiöihin. Empiirisessä osassa keskityttiin kehittämään Paroc Groupin hankintaprosessille suorituskyvyn mittareita. Tavoitteeseen pyrittiin vastaamaan luomalla kolme raporttia Paroc Groupin hankintaprosessin mittaamiseen. Varastonimikkeiden kustannusseurantaraportissa seurataan kustannusten muutoksia varastokulutuksen perusteella, varastoraportissa varastontehokasta käyttöä ja toimittajaraportissa toimittajien laskutusta. Tutkittaessa ERP -järjestelmän ja hankintaprosessin suorituskyvyn mittaamisen yhteyttä ilmeni, että ERP -järjestelmä tarjoaa erittäin paljon tarkkaa ja aina samanmuotoista dataa. Toisaalta saatavan datan yksipuolisuus rajoittaa mittareiden valintaa. Mittaamisen nopeutta järjestelmä joiltain osilta lisää, toisilta ei. Tiedon saanti on kuitenkin aina säännöllistä.

Exploration of the social dimension of corporate responsibility in a welfare state

This study focuses on corporate social responsibility (or CSR)as the latest dimension to emerge in the corporate responsibility and sustainability agenda, which in the recent past has rapidly risen to the top of the list of concerns for civil societies worldwide. Despite the continuing debates and discussions about the scope, benefits, and impacts of CSR to business and community in various sectors, levels, and types of society, many companies have moved forward to confront the opportunities and challenges of CSR. Thus, this study is about those proactive companies with a focus on the importance of CSR and its management inside and outside the company. It is an exploration and learning from the experience of Finnish companies, as well as other actors interested or involved in shaping the course of CSR, locally and globally. It also looks closely at how national culture affects the views, thinking, and management of CSR in a welfare state. This dissertation primarily draws on the analyses of information collected from a series of qualitative interviews and the existing literature in the area. This is complemented by an analysis of written and published documents on CSR from various sources. The results of the study give insightful information and detailed descriptions of a roadmap useful in learning and understanding CSR in Finnish companies. Despite the varying conceptual connotations, essential roadmap indicators point to the importance of framing CSR within the corporate responsibility concept, Finnish development and the welfare state system, globalization, stakeholders, and the pursuit of sustainable development as the main drivers of CSR, the remarkable progress of CSR in companies, and identification of key management areas and practices relevant to CSR. Similarly,the study reveals the importance of culture as essential in understanding and learning CSR. Finnish culture has a positive influence on the views, thinking, and management practices of CSR issues. Such a positive influence of culture, therefore, makes it easy for business people to discuss and understand CSR, because those CSR issues are already considered common and taken-for-granted by Finns and are implicit in the welfare state provisions. The experience of Finnish companies in implementing CSR policies in the supply chain is a concrete proactive step in advancing the message of CSR, that is, to bring companies and suppliers together to work on improving and strengthening relationships towards socially responsible practices worldwide. Such a forward step to deal with CSR issues in the supply chain reflects the companies' commitments and belief that CSR can be managed with the suppliers and gain positive benefits. Despite the problems and complexities, particularly in the global supply chain, managing CSR for Finnish companies presents new opportunities and challenges that are expected to intensify in the near future. The focus on CSR policy implementation inthe supply chain points to the importance of companies taking initiatives and forging cooperation with suppliers with the aim of addressing and improving CSR questions in the supply chains. The proactive stance of Finnish companies toward CSR is complemented by the active supporting role of important societalactors such as the government and NGOs. These actors carry out various promotional efforts and campaigns, thus bringing CSR into the mainstream of Finnish companies and strengthening the synergistic learning about CSR within the Finnish business and civil circles. The efforts of the government and NGOs to promote CSR are indicative of the importance of multipartite involvement and the emergence of better civil regulations. Likewise, their drive to learn from each other, exchange experiences, and contribute in CSR debates facilitated the evolution of CSRnetworks in the country. The results of this study add to the mounting evidence that CSR, in general, has created a new dimension in managing corporate sustainability. This study provides compelling empirical evidence and some direct quotations about CSR in the Finnish context. This information can be used to learn and gain new useful insights, approaches, and concepts for managing CSR.

Database Rights in Safe European Home: The Path to More Rigorous Protection of Information

1. Introduction "The one that has compiled ... a database, the collection, securing the validity or presentation of which has required an essential investment, has the sole right to control the content over the whole work or over either a qualitatively or quantitatively substantial part of the work both by means of reproduction and by making them available to the public", Finnish Copyright Act, section 49.1 These are the laconic words that implemented the much-awaited and hotly debated European Community Directive on the legal protection of databases,2 the EDD, into Finnish Copyright legislation in 1998. Now in the year 2005, after more than half a decade of the domestic implementation it is yet uncertain as to the proper meaning and construction of the convoluted qualitative criteria the current legislation employs as a prerequisite for the database protection both in Finland and within the European Union. Further, this opaque Pan-European instrument has the potential of bringing about a number of far-reaching economic and cultural ramifications, which have remained largely uncharted or unobserved. Thus the task of understanding this particular and currently peculiarly European new intellectual property regime is twofold: first, to understand the mechanics and functioning of the EDD and second, to realise the potential and risks inherent in the new legislation in economic, cultural and societal dimensions. 2. Subject-matter of the study: basic issues The first part of the task mentioned above is straightforward: questions such as what is meant by the key concepts triggering the functioning of the EDD such as presentation of independent information, what constitutes an essential investment in acquiring data and when the reproduction of a given database reaches either qualitatively or quantitatively the threshold of substantiality before the right-holder of a database can avail himself of the remedies provided by the statutory framework remain unclear and call for a careful analysis. As for second task, it is already obvious that the practical importance of the legal protection providedby the database right is in the rapid increase. The accelerating transformationof information into digital form is an existing fact, not merely a reflection of a shape of things to come in the future. To take a simple example, the digitisation of a map, traditionally in paper format and protected by copyright, can provide the consumer a markedly easier and faster access to the wanted material and the price can be, depending on the current state of the marketplace, cheaper than that of the traditional form or even free by means of public lending libraries providing access to the information online. This also renders it possible for authors and publishers to make available and sell their products to markedly larger, international markets while the production and distribution costs can be kept at minimum due to the new electronic production, marketing and distributionmechanisms to mention a few. The troublesome side is for authors and publishers the vastly enhanced potential for illegal copying by electronic means, producing numerous virtually identical copies at speed. The fear of illegal copying canlead to stark technical protection that in turn can dampen down the demand for information goods and services and furthermore, efficiently hamper the right of access to the materials available lawfully in electronic form and thus weaken the possibility of access to information, education and the cultural heritage of anation or nations, a condition precedent for a functioning democracy. 3. Particular issues in Digital Economy and Information Networks All what is said above applies a fortiori to the databases. As a result of the ubiquity of the Internet and the pending breakthrough of Mobile Internet, peer-to-peer Networks, Localand Wide Local Area Networks, a rapidly increasing amount of information not protected by traditional copyright, such as various lists, catalogues and tables,3previously protected partially by the old section 49 of the Finnish Copyright act are available free or for consideration in the Internet, and by the same token importantly, numerous databases are collected in order to enable the marketing, tendering and selling products and services in above mentioned networks. Databases and the information embedded therein constitutes a pivotal element in virtually any commercial operation including product and service development, scientific research and education. A poignant but not instantaneously an obvious example of this is a database consisting of physical coordinates of a certain selected group of customers for marketing purposes through cellular phones, laptops and several handheld or vehicle-based devices connected online. These practical needs call for answer to a plethora of questions already outlined above: Has thecollection and securing the validity of this information required an essential input? What qualifies as a quantitatively or qualitatively significant investment? According to the Directive, the database comprises works, information and other independent materials, which are arranged in systematic or methodical way andare individually accessible by electronic or other means. Under what circumstances then, are the materials regarded as arranged in systematic or methodical way? Only when the protected elements of a database are established, the question concerning the scope of protection becomes acute. In digital context, the traditional notions of reproduction and making available to the public of digital materials seem to fit ill or lead into interpretations that are at variance with analogous domain as regards the lawful and illegal uses of information. This may well interfere with or rework the way in which the commercial and other operators have to establish themselves and function in the existing value networks of information products and services. 4. International sphere After the expiry of the implementation period for the European Community Directive on legal protection of databases, the goals of the Directive must have been consolidated into the domestic legislations of the current twenty-five Member States within the European Union. On one hand, these fundamental questions readily imply that the problemsrelated to correct construction of the Directive underlying the domestic legislation transpire the national boundaries. On the other hand, the disputes arisingon account of the implementation and interpretation of the Directive on the European level attract significance domestically. Consequently, the guidelines on correct interpretation of the Directive importing the practical, business-oriented solutions may well have application on European level. This underlines the exigency for a thorough analysis on the implications of the meaning and potential scope of Database protection in Finland and the European Union. This position hasto be contrasted with the larger, international sphere, which in early 2005 does differ markedly from European Union stance, directly having a negative effect on international trade particularly in digital content. A particular case in point is the USA, a database producer primus inter pares, not at least yet having aSui Generis database regime or its kin, while both the political and academic discourse on the matter abounds. 5. The objectives of the study The above mentioned background with its several open issues calls for the detailed study of thefollowing questions: -What is a database-at-law and when is a database protected by intellectual property rights, particularly by the European database regime?What is the international situation? -How is a database protected and what is its relation with other intellectual property regimes, particularly in the Digital context? -The opportunities and threats provided by current protection to creators, users and the society as a whole, including the commercial and cultural implications? -The difficult question on relation of the Database protection and protection of factual information as such. 6. Dsiposition The Study, in purporting to analyse and cast light on the questions above, is divided into three mainparts. The first part has the purpose of introducing the political and rationalbackground and subsequent legislative evolution path of the European database protection, reflected against the international backdrop on the issue. An introduction to databases, originally a vehicle of modern computing and information andcommunication technology, is also incorporated. The second part sets out the chosen and existing two-tier model of the database protection, reviewing both itscopyright and Sui Generis right facets in detail together with the emergent application of the machinery in real-life societal and particularly commercial context. Furthermore, a general outline of copyright, relevant in context of copyright databases is provided. For purposes of further comparison, a chapter on the precursor of Sui Generi, database right, the Nordic catalogue rule also ensues. The third and final part analyses the positive and negative impact of the database protection system and attempts to scrutinize the implications further in the future with some caveats and tentative recommendations, in particular as regards the convoluted issue concerning the IPR protection of information per se, a new tenet in the domain of copyright and related rights.

Quelle perception ont les médecins de famille en Suisse de leur rôle dans la prévention et la promotion de la santé? : comprendre les barrières à l'implémentation

Introduction: The importance of health promotion and prevention and the potential of general practitioners (GPs) to conduct individual prevention procedures have been demonstrated in several studies. Clinical recommendations for screening and prevention activities, an important condition for success, are published regularly, but their implementation into daily practice does not necessarily follow. Information is lacking about the actual conditions of how prevention is carried out on a daily basis by Swiss GPs, about their perceptions and needs, their attitudes and the present barriers they face. Such information is essential for the development of new tools and programs targeting better implementation of clinical recommendations for prevention in primary care in Switzerland. Objectives: The objectives of the study were to analyze how Swiss GPs perceive their role in prevention by obtaining information regarding the following issues: What do disease prevention and health promotion mean to them? What are the current incentives and barriers they face? What are their ideas and suggestions to deal with these barriers? What are their needs and expectations regarding prevention guidelines and tools? Methods: We conducted a qualitative research project using focus groups to examine the questions mentioned above. A total of 13 focus groups took place including GPs from eight cantons: five groups in German- speaking Switzerland and eight in French- speaking Switzerland. Each group was composed of 4-11 GPs, making in total 102 participants, who were paid expenses to cover their participation. The sessions were audio-recorded and transcribed verbatim. Data analysis: Content analysis of the transcriptions began by classifying the data according to a typology, the first level of which was developed in line with the structure of the interview guide. This typology was extended by successively regrouping similar statements. Synopsis and interpretation was then performed on each category thus obtained. This research report is based on the results from the French-speaking cantons. Results: Physicians perceive a change in their role as a consequence of changes in society and the health system. They emphasize the importance of a personalized and long lasting relationship between the family doctor and his/her patient; a privileged position allowing them to perform individualized prevention activities, considered to be more effective, as they are appropriate to the specific situation and needs of the patient. They point out their need for training and for better information concerning prevention and health promotion interventions, and stress difficulties arising from the lack of a clear political signal conferring them with a mandate for prevention. -- INTRODUCTION L'importance de la prévention et de la promotion de la santé et le potentiel des médecins de famillea à mettre en oeuvre des mesures individuelles de prévention, de dépistage et de conseils, a été démontrée dans plusieurs études. Régulièrement durant les dernières années, de nombreuses associations médicales ont publié des recommandations cliniques concernant les activités de dépistage et de prévention qui sont une condition essentielle pour le succès, mais ne sont pas forcément appliquées de manière systématique dans la pratique médicale quotidienne. Des contraintes spécifiques contribuent à l'écart entre le désir des médecins de pratiquer une médecine préventive et la réalité d'un cabinet médical. Nous n'avons que peu de données sur les conditions actuelles dans lesquelles la prévention et la promotion de la santé sont réalisées par les médecins de famille suisses dans leur travail quotidien. Des informations précises et représentatives sur leurs perceptions et leurs besoins, leurs attitudes et les contraintes auxquelles ils sont confrontés manquent. Or ces données sont essentielles dans le développement de nouveaux outils et programmes visant une meilleure implémentation des recommandations cliniques dans le domaine de la prévention et la promotion de la santé dans la médecine de famille en Suisse. OBJECTIFS Le développement de concepts pour une prévention systématique ainsi que d'outils adéquats, tout comme l'amélioration des conditions qui permettent une implémentation à grande échelle, implique, avant tout, l'analyse de la perception que les médecins de famille suisses ont de leur rôle dans la prévention. Par conséquent, cette étude a eu pour objectif d'obtenir des informations concernant les questions suivantes : ? Que signifient la prévention et la promotion de la santé pour les médecins de famille suisses ? ? Quelles sont leurs incitations et les barrières rencontrées ? ? Quelles sont leurs idées et leurs suggestions pour faire face à ces contraintes ? ? Quels sont leurs besoins et leurs attentes concernant les outils pour la prévention ? METHODES Nous avons mené un projet de recherche qualitative en utilisant la technique des focus groups pour examiner les questions mentionnées ci-dessus. Une telle technique de collecte de données est particulièrement adaptée à un domaine où l'on connaît mal les perceptions des parties prenantes. Nous avons mené 13 focus groups au total, comprenant des médecins issus de huit cantons: cinq groupes ont eu lieu en Suisse alémanique et huit groupes en Suisse romande. Chaque groupe était composé de 4 à 11 médecins de famille, avec au total 102 participants qui ont été défrayés pour leur participation. Les séances ont été audio-enregistrées et transcrites. ANALYSE DES DONNEES L'analyse du contenu des transcriptions a commencé par la classification des données selon une typologie dont le premier niveau a été développé à partir de la structure de la grille d'entretiens. Cette typologie a été affinée et élargie en regroupant successivement des propos similaires. Une synthèse a été effectuée pour chaque catégorie. Ce rapport est basé sur les résultats de l'analyse des données des cantons francophones. RESULTATS Les médecins perçoivent un changement de leur rôle dans une société et dans un système de santé qui évoluent. Ils soulignent l'importance de la relation personnalisée et durable du médecin de famille avec son patient, atout précieux, qui leur permet de réaliser des activités de prévention individualisées et adaptées à la situation et aux besoins du patient, considérées plus efficaces. Afin de surmonter leur doutes et découragement par rapport aux interventions de prévention, ils pointent la nécessité d'une formation aux nouvelles connaissances en prévention et promotion de la santé et d'une meilleure information aux médecins quant à leur efficacité et importance. Ils montrent le besoin d'un signal clair des politiques par rapport à l'attribution de ce mandat aux médecins de famille et de leur reconnaissance en tant qu'acteur de prévention dans le système de santé.
