An immunoenzymatic assay for the diagnosis of hepatitis A utilising immunoglobulin Y

The detection of anti-hepatitis A virus (HAV) antibody levels by diagnostic kits in the convalescent period of disease generally use immunoglobulin G (IgG), which is expensive. An alternative to IgG is immunoglobulin Y (IgY), an immunoglobulin antibody encountered in birds and reptiles. The aim of this study was to develop a competitive immunoenzymatic assay to measure total anti-HAV antibody levels using anti-HAV IgY as the capture and conjugated immunoglobulins. For this purpose, anti-HAV IgY was conjugated to horseradish peroxidase (HRP) and the optimal dilution of HRP-conjugated antibodies was evaluated to establish the competitive immuneenzymatic assay. The results obtained from our "in-house" assay were plotted on a receiver operator curve, which showed a sensitivity of 95% and a specificity of 98.8%, demonstrating that a competitive anti-HAV IgY immunoenzymatic assay developed "in house" could be used as an alternative to commercial assays that utilise IgG.

Bacterial-induced protection against allergic inflammation through a multicomponent immunoregulatory mechanism.

Background Airborne microbial products have been reported to promote immune responses that suppress asthma, yet how these beneficial effects take place remains controversial and poorly understood. Methods We exposed mice to the bacterium Escherichia coli and subsequently induced allergic airway inflammation through sensitization and intranasal challenge with ovalbumin. Results Pulmonary exposure to the bacterium Escherichia coli leads to a suppression of allergic airway inflammation. This immune modulation was neither mediated by the induction of a T helper 1 (Th1) response nor regulatory T cells; however, it was dependent on Toll-like receptor 4 (TLR4) but did not involve TLR desensitisation. Dendritic cell migration to the draining lymph nodes and activation of T cells was unaffected by prior exposure to E.coli, while dendritic cells in the lung displayed a less activated phenotype and had impaired antigen presentation capacity. Consequently, in situ Th2 cytokine production was abrogated. The suppression of airway hyper-responsiveness was mediated through the recruitment of gd T cells; however, the suppression of dendritic cells and T cells was mediated through a distinct mechanism that could not be overcome by the local administration of activated dendritic cells, or by the in vivo administration of tumour necrosis factor a. Conclusion Our data reveal a localized immunoregulatory pathway that acts to protect the airways from allergic inflammation.

BAY 41-2272 activates host defence against local and disseminated Candida albicans infections

In our previous study, we have found that 5-cyclopropyl-2-[1-(2-fluoro-benzyl)-1H-pyrazolo[3,4-b]pyridine-3-yl]-pyrimidin-4-ylamine (BAY 41-2272), a guanylate cyclase agonist, activates human monocytes and the THP-1 cell line to produce the superoxide anion, increasing in vitro microbicidal activity, suggesting that this drug can be used to modulate immune functioning in primary immunodeficiency patients. In the present work, we investigated the potential of the in vivo administration of BAY 41-2272 for the treatment of Candida albicans and Staphylococcus aureus infections introduced via intraperitoneal and subcutaneous inoculation. We found that intraperitoneal treatment with BAY 41-2272 markedly increased macrophage-dependent cell influx to the peritoneum in addition to macrophage functions, such as spreading, zymosan particle phagocytosis and nitric oxide and phorbol myristate acetate-stimulated hydrogen peroxide production. Treatment with BAY 41-2272 was highly effective in reducing the death rate due to intraperitoneal inoculation of C. albicans, but not S. aureus. However, we found that in vitro stimulation of peritoneal macrophages with BAY 41-2272 markedly increased microbicidal activities against both pathogens. Our results show that the prevention of death by the treatment of C. albicans-infected mice with BAY 41-2272 might occur primarily by the modulation of the host immune response through macrophage activation.

El blog y otras herramientas comunicativas de la biblioteca del Área de Gestión Sanitaria Este de Málaga - Axarquía

In 2006 the Library of the Andalusian Public Health System (BVSSPA) is constituted as a Virtual Library which provides Resources and Services that are accessed through inter-hospital local area network (corporate intranet) and Internet. On the other hand, the Hospital de la Axarquia still did not have any institutional or self-presence on the Internet and the librarian ask the need to create a space for communication with the "digital users" of the Library of the area through a website. MATERIALS AND METHODS. The reasons why we opted for a blog were: -It was necessary to make no financial outlay for its establishment. It allowed for great versatility, both in its administration and in its management by users. -The ability to compile on the same platform different Web 2.0 communication tools. Between different options available we chose Blogger Google Inc. The blog allowed entry to the 2.0 services or Social Web in the library. The benefits offered were many, especially the visibility of the service and communication with the user. 2.0 tools that have been incorporated into the library are: content syndication (RSS) which allowed users to stay informed about updates to the blog. Share documents and other multimedia as presentations through SlideShare, images through Flickr or Picasa, or videos (YouTube). And the presence on social network like Facebook and Twitter. RESULTS. The analysis of the activity we has been traking by Google Analytics tool, helping to determine the number of blog visits. Since its stablishment, on November 17th 2006, until November 29th 2010 the blog has received 15,787 visitors, 38,422 page views were consulted, at each visit on average 2.4 pages were consulted and each visit has an average stay at the site of 4'31''. DISCUSSION. The blog has served as a communication and information tool with the user. Since the creation of the blog we have incorporated technologies and tools to interact with the user. With all the tools used we have applied the concept of "open source" and the contents were generated from the activities organized in the Knowledge Management Unit from the anatomo-clinical sessions, the training activities, dissemination events, etc. The result has been the customization of library services, contextualized in the Knowledge Management Unit - Axarquia. In social networks we have shared information and files with the professionals and the community. CONCLUSIONS. The blog has allowed us to explore technologies that allow us to communicate with the user and the community, disseminate information and documents with the participation of users and become the "Interactive Library" we aspire to be.

Permanent demand excess as business strategy: an analysis of the Brazilian higher-education market

Many Higher Education Institutions (HEIs) establish tuition below the equilibrium price to generate permanent demand excess. This paper first adapts Becker’s (1991) theory to understand why the HEIs price in this way. The fact that students are both consumers and inputs on the education production process gives rise to a market equilibrium where some firms have excess demand and charge high prices, and others charge low prices and have empty seats.Second, the paper analyzes this equilibrium empirically. We estimated the demand for undergraduate courses in Business Administration in the State of São Paulo. The results show that tuition, quality of incoming students and percentage of lecturers holding doctorates degrees are the determining factors of students’ choice. Since the student quality determines the demand for a HEI, it is calculated what the value is for a HEI to get better students; that is the total revenue that each HEI gives up to guarantee excess demand. Regarding the “investment” in selectivity, 39 HEIs in São Paulo give up a combined R$ 5 million (or US$ 3.14 million) in revenue per year per freshman class, which means 7.6% of the revenue coming from a freshman class.

Planificació pel canvi de plataforma del CPD cap a l'e-administració

L'objectiu del treball és recollir la informació precisa referent als requeriments tècnics que s'haurien de contemplar en cas que una organització decidís iniciar un projecte de modernització del CPD que permetés l'estabilitat i l'escalabilitat del sistema, i una transició i integració de noves aplicacions i serveis d'administració electrònica.

Immigració i desafecció política a l'espai local: la instrumentalització política de la immigració a Catalunya i Gran Bretanya

El projecte ha tingut com a objectiu principal abordar la instrumentalització política de la immigració per part de partits polítics de nova extrema dreta. Aquest fenomen, que ha adquirit una gran rellevància a gran part dels països europeus, està adquirint una creixent rellevància en els casos britànic i català a partir de, entre altres coses, l'emergència electoral dels partits Plataforma per Catalunya i British National Party. En aquest sentit, el projecte ha tractat de desenvolupar una recerca que produís un conjunt de dades i coneixements que permetessin abordar de forma fonamentada un fenomen “nou” en el context català i que, fins al moment, ha rebut escassa atenció per part del món acadèmic. Dins d’aquest objectiu cal destacar el fet que la àmplia experiència de l’equip investigador britànic en l’anàlisi de la nova extrema dreta ha permès que els investigadors catalans poguessin desenvolupar la seva recerca recolzant-se i dialogant en la seva contrapart britànica. Els resultats de la recerca són certament novedosos i representaran una important contribució al coneixement d’aquest fenomen. Així, en el marc de la recerca s’han desenvolupat una sèrie d’entrevistes a membres i a votants de PxC, així com una enquesta a votants i una anàlisi agregada sobre el vot al partit. En aquest sentit, cal destacar que és la primera vegada que s’aconsegueixen aquest tipus de dades. Un fet que està fent, i farà, que la seva explotació i divulgació adquireixi una gran rellevància tant en el món acadèmic com en el de les administracions públiques. Finalment, convé ressaltar que el projecte també ha servit per consolidar la relació entre els equips d’investigació britànic i català i per impulsar la inserció de l’equip català en les xarxes europees d’investigació sobre aquesta matèria.

Lastenkulttuuripoliittisesta ohjelmasta tilanvuokraustoimintaan : lastenkulttuuritarjonnan muodostuminen Helsingin alueellisissa kulttuurikeskuksissa

Then aim of this thesis is to investigate children's culture in the regional cultural centres of Helsinki, namely Stoa, Malmitalo and Kanneltalo. The main objective was to identify how the center's repertoire for children forms. Moreover, a further research question was how different fields of art as well as proposals for action defined by the Children's Culture Programme, are portrayed in the repertoire of the regional cultural centres. The Ministry of Education's missions are to plan cultural and artistic policies, to support the industry financially, and to prepare cultural legislation. The Ministry promotes children's culture with a variety of programs and projects. The basis of the thesis is formed by the Finnish Ministry of Education's Children's Culture Programme, published in 2003. The goal of the programme is to give direction to the promotion of children's culture from 2003 to 2007. The programme presented proposals for action in different fields of art that are directed towards a broad range of implementors. In addition, in the theoretical section the focus is on the research of the Ministry of Education, the Art Council of Finland and the Municipalities. The research investigates the roles in children's culture as well as the activities of regional cultural centers. The qualitative analysis has been conducted by interviewing the employees of these regional cultural centers. The factors that affect and hinder the composition of the children's programme's repertoire are analysed based on the results of the interviews. The factors that affect the composition are the supply, the facilities and the possibilities provided by cooperation. The results section examines how the Children's Cultural Programme presents different fields of art. What is also taken into account is focal points connected to them, the proposals for action when building the repertoire. The results of the interviews indicate that the repertoire of the regional cultural centres is very diverse and it often meets the propositions of the children's cultural programme. However, the contents of the program were unknown for many. Various fields of art have been catered for in the children's repertoire and the supply is of good quality. The City of Helsinki Cultural Office's upcoming change in the administration was also mentioned, as the interviewees contemplated its future effects.

Automaattisen nukleiinihappoeristyslaitteen ja reaaliaikaisen PCR-menetelmän soveltuvuus herpes simplex -virusten keskushermostoinfektiodiagnostiikkaan

Keskushermosto- ja neonataali-infektiot ovat herpes simplex -virusten aiheuttamista taudeista vakavimpia. Niihin on olemassa lääkitys, joka on tehokkain, kun se aloitetaan aivan sairauden alkuvaiheessa. Näiden infektioiden diagnostiikassa PCR-menetelmä on herkin. Tämä menetelmä on kuitenkin työläs ja aikaa vievä, joten uudet nopeammat menetelmät ovat tervetulleita. Opinnäytetyö tehtiin HUSLABin virologian osastolle. Työssä testattiin QIAGENIN artus®HSV-1/2 LC PCR-reagenssipakkausta, joka on tehty käytettäväksi Roche diagnosticsin reaaliaikaisella PCR-laitteella LightCyclerillä. Lisäksi työssä testattiin automaattista bioMérieuxin NucliSens easyMAG- nukleiinihappoeristyslaitetta. Referenssinä käytettiin HUSLABin virologian osastolla testaushetkellä käytössä olevia menetelmiä. Reaaliaikaisen PCR-menetelmän herkkyyttä testattiin positiivisilla HSV-1 ja HSV-2 kontrollilaimennussarjoilla. Menetelmän oikeellisuutta testattiin määrittämällä laaduntarkkailu- ja potilasnäytteitä, jotka olivat likvoria. Tuloksia verrattiin QCMD:n antamiin ja perinteisellä ”in house”- PCR-menetelmällä saatuihin referenssituloksiin. Spesifisyyttä testattiin muiden ihmisten herpesvirusten positiivisilla kontrolleilla. Automaattisen nukleiinihappoeristysmenetelmän toimivuutta testattiin HSV-positiivisilla ja -negatiivisilla likvornäytteillä, jotka oli aikaisemmin eristetty fenoli-kloroformiuutolla. Tulokset QIAGENIN artus®HSV-1/2 LC PCR-reagenssipakkauksesta olivat hyviä. Kont-rollilaimennussarjan määrityksessä reaaliaikainen PCR-menetelmä osoittautui perinteistä ”in house”- PCR-menetelmää herkemmäksi. Potilasnäytteiden määrityksessä tulokset olivat yhtenevät. EasyMAG- nukleiinihappoeristysmenetelmällä eristettyjen potilasnäytteiden määrityksistä saadut tulokset olivat myös hyviä. Kun tuloksia verrattiin fenoli-kloroformiuutolla saatuihin tuloksiin, olivat tulokset yhtä näytettä lukuun ottamatta yhtenevät. Molemmat testattavat menetelmät ovat nopeita ja virhelähteiden mahdollisuus on vähäisempi kuin perinteisessä ”in house”-PCR menetelmässä ja fenoli-kloroformiuutolla nukleiinihappoa eristettäessä. Tutkimusten tulokset osoittivat molempien menetelmien soveltuvan hyvin HSV:n eristykseen ja määritykseen likvornäytteistä.

Gestão dos recursos hídricos no processo de desenvolvimento sustentável de Cabo Verde: uma proposta

A água é vital para a sobrevivência, saúde e dignidade do ser humano e uma fonte fundamental para o seu desenvolvimento. As reservas de água potável no mundo estão sob pressão constante embora muitos ainda não tenham acesso a esse precioso líquido para atender ás necessidades básicas. A água é um recurso natural com valor económico, estratégico e social. A percepção da escassez tem levado governos, a reorganizar o ambiente institucional e definir novos direitos de propriedade por meio de um sistema de gestão participativo e descentralizado que estimule a utilização do recurso de forma racional. A investigação está direccionada à gestão e à implementação da Lei n.º 41/II/84 de 18 de Junho, que Aprova o Código de Águas que estabelece as bases gerais do regime jurídico de propriedade, protecção, conservação, desenvolvimento, administração e uso dos recursos. O enfoque da pesquisa é as Instituições Governamentais que lidam com a água e as Associações de Bacias hidrográficas que, com os seus olhares e saberes, contribuem com informações para que se construa uma Proposta de Modelo de Gestão numa perspectiva de sustentabilidade. A proposta de modelo pretende contribuir para uma gestão sustentada. A pesquisa é do tipo qualitativa e usa como metodologia o Estudo de Caso. Foi constatada a complexidade da gestão das águas em Cabo Verde, na qual existem ainda muitos entraves e desafios. A Bacia Hidrográfica é a unidade básica de gestão, onde as Associações, as Câmaras Municipais, os Serviços Autónomos de Água e Saneamento, o Instituto Nacional de Gestão dos recursos Hidricos desempenham o papel de gerí-la e preservá-la. Foram identificados como dificuldades: a posse da água não está bem clara, o que dificulta a gestão da Bacia; os conflitos sociais são frequentes quanto ao uso da água no que tange à poluição; a população rural não está devidamente contemplada na gestão dos recursos hídricos. Por fim, constatou-se que Cabo Verde possui as ferramentas para a evolução da Gestão dos Recursos Hídricos, que é o Código de Água. Water is vital for the survival, health and dignity of the human being and a basic source for development. The drinking waters reserves in the world are under constant pressure. The water can be considered a natural resource with economic, strategically and social values. The perception of the scarcity has taken governments, to reorganize the institutional environment and to define new rights of property by means of participation and decentralized system of management that stimulates the use of the resource in rational form. This investigation addressed the Administration of Water Resources in Cabo Verde and the implementation of Law n.º 41/II/84 of 18 of June, which established the National Policy of Water Resources and the National System of Management. The approach of the research is the Governmental Institutions that deal with the water and the Associations that, at a glance, contribute with information that builds the proposal of water resources management in a sustainability perspective. The proposal has as objective to provide subsidies to advance more and more the research regarding sustainability in the administration of waters. The research was qualitative and it used as methodology the Study Case. We identified as difficulties: the ownership of the water is not well clear; the social conflicts are frequent concerning how to use the water. Finally, it was evidenced that Cape Verde has the tools for the evolution of water resources management, which is the Water Code.

HTPSELEX--a database of high-throughput SELEX libraries for transcription factor binding sites.

HTPSELEX is a public database providing access to primary and derived data from high-throughput SELEX experiments aimed at characterizing the binding specificity of transcription factors. The resource is primarily intended to serve computational biologists interested in building models of transcription factor binding sites from large sets of binding sequences. The guiding principle is to make available all information that is relevant for this purpose. For each experiment, we try to provide accurate information about the protein material used, details of the wet lab protocol, an archive of sequencing trace files, assembled clone sequences (concatemers) and complete sets of in vitro selected protein-binding tags. In addition, we offer in-house derived binding sites models. HTPSELEX also offers reasonably large SELEX libraries obtained with conventional low-throughput protocols. The FTP site contains the trace archives and database flatfiles. The web server offers user-friendly interfaces for viewing individual entries and quality-controlled download of SELEX sequence libraries according to a user-defined sequencing quality threshold. HTPSELEX is available from ftp://ftp.isrec.isb-sib.ch/pub/databases/htpselex/ and http://www.isrec.isb-sib.ch/htpselex.

O contributo da contabilidade numa gestão transparente das OSFL - Caso: ADECO

Na actualidade, tem-se cada vez mais a consciência da necessidade e da importância de ter uma informação financeira credível e em tempo oportuno. A informação financeira passou a ser a base para avaliação do desempenho dos gestores, assim como para análise da situação económico-financeira das Organizações. A informação só é útil para tomada de decisão se tiverem as seguintes características qualitativas: Compreensibilidade, Relevância, Fiabilidade e Comparabilidade. No ambiente concorrencial em que as Organizações estão inseridas, a Contabilidade tem um papel fulcral como instrumento de tomada de decisão. As Organizações que têm como objectivos acções sociais, actuam nas áreas como: culturais e recreativas, solidariedade social, promoção do desenvolvimento comunitário, educacionais, de protecção ao ambiente, Saúde e da promoção da higiene, entre outros. Como essas Organizações não têm com objectivo o lucro, é necessário ter uma boa gestão e para que isso seja possível, é preciso ter-se instrumentos capazes para que isso seja possível e é neste âmbito que a Contabilidade entra como um auxílio para a gestão, como ferramenta capaz de mensurar e controlar processos, resultados e impactos nos projectos executados, a fim de que seus objectivos sociais sejam alcançados de uma forma consistente com o planeado. A sustentabilidade, a necessidade de demonstração e de aplicação dos recursos obtidos é um forte desafio que as Organizações do terceiro sector têm de ultrapassar e, neste âmbito, a Contabilidade pode constituir um meio importante para atingir esses objectivos, através da demonstração dos resultados alcançados. Nesta base, o contributo da Contabilidade na gestão das OSFL tem-se acentuado cada vez mais, demonstrando transparência na apresentação das suas contas, facilitando na captação de recursos e na fidelização dos seus parceiros e financiadores. Nowadays it has become increasingly aware of the need and importance of having credible and timely financial information. The financial information started to be the base for evaluation of the managers acting, as well as for analysis of the economicfinancial situation of the company. The information is only useful for socket of decision if they have the following qualitative characteristics: Comprehensive, Relevance, Reliable and Comparability. In the atmosphere concurrencies in that the Organizations are inserted the accounting has a crucial paper as instrument of socket of decision in the Organizations. The Organizations that have as purpose social action as for instance: cultural and recreational, social solidarity, promotion of the development community, education, of protection to the atmosphere, health and of the promotion of the hygiene, among others. As those Organizations don't have with objective the profit, it is necessary to have a good administration and for that to be possible, it is necessary to have capable instruments for that to be possible and it is in this extent that the accounting enters as an aid for the administration, as tool capable to measure and to control processes, results and impacts in the executed projects, so that their social objectives are reached in a solid way with the planed. Sustainability, the demonstration of the achieved results and the application of resources collected are strong challenges that the Organizations of the third sector have to overcome. To that extent, Accounting can contribute as an important way to reach those objectives through the demonstration of resources collected. In this base, the contribution of the Accounting has been accentuating more and more in the administration of the nonprofit organizations, demonstrating transparency in the presentation of their finance statements, facilitating the fundraising of Organizations and loyal partners and funders.
