Accidental infection by Trypanosoma cruzi follow-up by the polymerase chain reaction: case report

We report a case of accidental infection by Trypanosoma cruzi in a 42-year-old female patient who presented an inoculation chagoma. Laboratory confirmation was based on examination of fresh blood, Giemsa-stained blood smear, immunoenzyme test (EIA-IgG), indirect immunofluorescence (IIF-IgM, IgG) and polymerase chain reaction (PCR). Only the PCR gave a positive result, and the EIA test was inconclusive. Two treatments with benznidazole were necessary. PCR was the only technique that continued to give positive results for approximately two months (65 days, or 2.2 months) following the second treatment and negative results from 96 days (3.2 months) to 850 days (28.3 months). We concluded that the presence of an inoculation chagoma and use of PCR were important and decisive for diagnosis and follow-up of the case.

Relating the spatial component and users interests to improve applications based on questions, petitions and participatory processes

Nowadays, participatory processes attending the need for real democracy and transparency in governments and collectives are more needed than ever. Immediate participation through channels like social networks enable people to give their opinion and become pro-active citizens, seeking applications to interact with each other. The application described in this dissertation is a hybrid channel of communication of questions, petitions and participatory processes based on Public Participation Geographic Information System (PPGIS), Participation Geographic Information System (PGIS) and ‘soft’ (subjective data) Geographic Information System (SoftGIS) methodologies. To achieve a new approach to an application, its entire design is focused on the spatial component related with user interests. The spatial component is treated as main feature of the system to develop all others depending on it, enabling new features never seen before in social actions (questions, petitions and participatory processes). Results prove that it is possible to develop a working application mainly using open source software, with the possibility of spatial and subject filtering, visualizing and free download of actions within application. The resulting application empowers society by releasing soft data and defines a new breaking approach, unseen so far.

Aspergilli and Penicillia related to the surface of ripening italian grana type cheese and its ripening environment

Information available on the mycoflora associated to ripening Italian “grana type” cheese is very poor. Recently, ochratoxin A (OTA) was detected in samples of packed grated cheese [1]; therefore, the need of information to perform a risk management was highlighted. Moreover, sterigmatocystin (STC) has been reported in cheese and it is considered an emerging problem. Despite the fact that both of them are mycotoxins included in group 2B by IARC [2,3], no European regulation exists. So, the main goal of this work is to give for the first time a general overview about Penicillia and Aspergilli growing on the surface of ripening “grana type” cheese, with particular attention on mycotoxigenic species. To perform this, in 2013 and 2014 crust samples were scratched from ripening grana cheese wheels and also Potato Dextrose Agar plates were exposed to monitor ripening house air. Then, 140 fungal isolates were randomly chosen, purified and monosporic colonies were obtained for their identification at specie level. A polyphasic approach is followed, based on morphological characterisation, toxic extrolites profiling and gene sequencing. The identification is still in progress, but the first results based on the morphological approach showed the presence of mycotoxigenic Aspergilli (Aspergillus flavus and A. versicolor) and various Penicillium species; among them Penicillium chrysogenum, P. implicatum and P. solitum were identified. Only P. chrysogenum was reported to produce the mycotoxins cyclopiazonic acid (CPA) and roquefortine-C (ROQ-C) [4]. These results will be presented and discussed. [1] A. Biancardi, R. Piro, G.

Social Multi-Criteria Evaluation (SMCE)

The main argument developed here is the proposal of the concept of “Social Multi-Criteria Evaluation” (SMCE) as a possible useful framework for the application of social choice to the difficult policy problems of our Millennium, where, as stated by Funtowicz and Ravetz, “facts are uncertain, values in dispute, stakes high and decisions urgent”. This paper starts from the following main questions: 1. Why “Social” Multi-criteria Evaluation? 2. How such an approach should be developed? The foundations of SMCE are set up by referring to concepts coming from complex system theory and philosophy, such as reflexive complexity, post-normal science and incommensurability. To give some operational guidelines on the application of SMCE basic questions to be answered are: 1. How is it possible to deal with technical incommensurability? 2. How can we deal with the issue of social incommensurability? To answer these questions, by using theoretical considerations and lessons learned from realworld case studies, is the main objective of the present article.

Percepció socioambiental del present i el futur del sector ramader a Esterri de Cardós

En aquest projecte s’ha realitzat una diagnosi socioambiental de la ramaderia en el municipi d’Esterri de Cardós, situat a la comarca del Pallars Sobirà, i que es troba dins dels límits del Parc Natural de l’Alt Pirineu. Dins del seu àmbit és un municipi peculiar degut a la quantitat de ramaders, set, i a la mitjana d’edat, que és força jove. La situació actual del sector és complicada atès el poc benefici que generen les explotacions, ja que els costos de manteniment són cada vegada més grans i els ingressos no augmenten en la mateixa proporció. És per això que des de fa uns anys els ajuts econòmics han esdevingut un factor clau per mantenir el sector. La seva continuïtat depèn de, entre altres coses, la dedicació en el sector de les generacions futures i ara per ara sembla que aquestes es decanten cada vegada més per altres tipus d’ocupacions. És per això que han de treballar totes les parts conjuntament per poder solucionar aquesta situació i que no esdevingui un problema insalvable en els pròxims anys.

Il desiderio materno nei casi di maltrattamento infantile

The work of this thesis would like to investigate two particular questions about the care of underage: on the one hand, the maltreatment, and the mother's desire on the other hand. About the first, this proposal try to underscore the elaborate irregularity and disparity related to this phenomenon and his historical evolution. The objective's thesis propose to underline that the abuse crosses the crisis of educational dimension inside and outside the family. We are talking about a type of crisi that places at the origin of a specific clinic and that it is about the maltreatment designated, at the same time, to cope with the educational void and with the ill-treated under age's hardships. The so-called clinic of the maltreatment horns, therefore, with the purpose to join and to set in order the normative and educational aspects. However, the prescriptive requirement is intended to measure against the same one crisis in a paradoxical way; the laws and the juveniles court must make up for the lack absence of the rules that characterized the maltreatment, getting around to use the typical reference that traditionally were been at the base of the educational way's construction. The same crimes on underage often found in the father the responsibility. The requirements and the therapeutic needs has utilized the theoretical construct of the trauma as the key line of clinical practice. On the one hand, the trauma was been paired controversially to the psychoanalytical concepts as the notion of the phantom, in the same manner that the objective truth is been opposed to the notion of the imagination and fantasy; on the other hand, the trauma was gotten to be the mark and the characteristic that defined the individual identity of the mistreated persons, regardless of the person's clinical structure or, generally, regardless of the their individual position. Both the normative demand and therapeutic converge on the idealization of the imaginary figure that is able to supply to every type of maltreatment: the mother. This position is connected on theoretical construct well-established in the mythology, that associated the mother figure to a natural dimension; this is related to the second point at issue: the mother's desire. The awareness of the mother figure in natural and idealized terms describes accusingly and negatively the trauma, without seeing the difference between trauma that helps to give a structure to the individual position from the trauma solely devastating. The mother's mythology, therefore, is in an evident antagonism with the female figure and woman's sexuality. In these way the maltreatment's clinic suggests that a woman is able to be a mother only when she doesn't appreciate the rule of female. This situation preclusives a comparison with own sexuality and gives to the women a complex of castration. The clinic cases reported highlight as these difficulties are the expression of the familiarity's heredity that wasn't been sufficiently elaborated. This condition (into the relation between mother and his child) turn the infant in the incapacity to symbolized and it doesn't help him to accede to the positive trauma, to the language and to the edipic rule; this is the reason why the child toils difficulties to approach to own personality and to orient himself in the relation with his body, with the body of the adults and the same age children.

Geometria integral i convexitat en espais de curvatura holomorfa constant

En aquest treball es tracten qüestions de la geometria integral clàssica a l'espai hiperbòlic i projectiu complex i a l'espai hermític estàndard, els anomenats espais de curvatura holomorfa constant. La geometria integral clàssica estudia, entre d'altres, l'expressió en termes geomètrics de la mesura de plans que tallen un domini convex fixat de l'espai euclidià. Aquesta expressió es dóna en termes de les integrals de curvatura mitja. Un dels resultats principals d'aquest treball expressa la mesura de plans complexos que tallen un domini fixat a l'espai hiperbòlic complex, en termes del que definim com volums intrínsecs hermítics, que generalitzen les integrals de curvatura mitja. Una altra de les preguntes que tracta la geometria integral clàssica és: donat un domini convex i l'espai de plans, com s'expressa la integral de la s-èssima integral de curvatura mitja del convex intersecció entre un pla i el convex fixat? A l'espai euclidià, a l'espai projectiu i hiperbòlic reals, aquesta integral correspon amb la s-èssima integral de curvatura mitja del convex inicial: se satisfà una propietat de reproductibitat, que no es té en els espais de curvatura holomorfa constant. En el treball donem l'expressió explícita de la integral de la curvatura mitja quan integrem sobre l'espai de plans complexos. L'expressem en termes de la integral de curvatura mitja del domini inicial i de la integral de la curvatura normal en una direcció especial: l'obtinguda en aplicar l'estructura complexa al vector normal. La motivació per estudiar els espais de curvatura holomorfa constant i, en particular, l'espai hiperbòlic complex, es troba en l'estudi del següent problema clàssic en geometria. Quin valor pren el quocient entre l'àrea i el perímetre per a successions de figures convexes del pla que creixen tendint a omplir-lo? Fins ara es coneixia el comportament d'aquest quocient en els espais de curvatura seccional negativa i que a l'espai hiperbòlic real les fites obtingudes són òptimes. Aquí provem que a l'espai hiperbòlic complex, les cotes generals no són òptimes i optimitzem la superior.

How collaboration could contribute to make Catalan journals visible on the Internet?

Cooperation between libraries is a universal language spoken in different dialects. In 1996 the libraries of the state-funded universities and the National Library of Catalonia (Spain) formed the Consortium of Academic Libraries of Catalonia (CBUC) to act as a channel for cooperation. The organization and activities of CBUC are an example of how this universal language has been adapted to the specific characteristics of the Libraries of Catalonia. Catalonia is an autonomous region of Spain with 7 million inhabitants with its own language, history and traditions and with a strong feeling of own identity that facilitates the cooperation. Thanks to this (and also to the hard work of the member libraries), since then, CBUC has created a union catalogue, an interlibrary lending program, the Digital Library of Catalonia, a cooperative store, different cooperatives repositories and other cooperation programs. One of these cooperatives repositories is RACO (Catalan Journals in Open Access, www.raco.cat) where can be consulted, in open access, the full-text articles of scientific, cultural and scholar Catalan journals. The main purpose of RACO is to increase the visibility and searches of the journals included and to spread the scientific and academic production published in Catalonia. This purpose makes specific in three aims: encourage the electronic edition of Catalan journals; be the interface that allows the whole search of all the journals and provide the instruments for its preservation. There are currently 244 journals in RACO, that includes more than 85.000 articles (80% in OA) from 50 publishing institutions. Since it got into operation it has had more than 4 millions of queries. These 244 journals offer the full-text of all the published issues. Nevertheless, some journal can have a delay between the introduction of the table of contents and the full-text for the recent issues. From 2005 we have a plan of retrospective digitization that has allowed to digitize more than 350.000 pages of back issues. The RACO repository works with the open source program OJS (Open Journal Systems, http://pkp.sfu.ca/ojs/) and uses Dublin Core Metadata and the interoperability protocol created by Open Archives Initiative (OAI) which allows to increase the visibility of the articles published in journals offering oneself together with other international repositories.

Atteintes cardiaques dans les connectivites: l'exemple du lupus érythémateux systémique [Cardiac involvement in connective tissue disease: the example of systemic lupus erythematosus]

When we think of cardiac affection in the context of systemic lupus erythematosus (SLE), we usually refer to pericarditis first. As frequent as this affection is, it is actually not the only cardio-vascular problem that occurs with this systemic inflammatory disease. Are the cardiac events--ranging from multiple heart valve involvements to increased cardiovascular risks--clinically significant? And are they involving a specific follow-up, treatment or support? We are therefore trying to evaluate these questions in order to give some recommendations to any practitioners following up a lupus patient, or a patient suffering from any other inflammatory systemic disease.

La història es repeteix?: estudi comparatiu de la crisi del 29 amb l'actual

Treball de recerca realitzat per un alumne d'ensenyament secundari i guardonat amb un Premi CIRIT per fomentar l'esperit científic del Jovent l'any 2009. L’objectiu d’aquest treball ha estat donar pautes de reflexió sobre la crisi i el moment econòmic actual. Es volia valorar si era certa la idea que la situació econòmica dels nostres dies té certs paral•lelismes amb la crisi que va patir el món occidental el 1929. Per tal d’establir la veracitat de la hipòtesi plantejada es va dissenyar un model d’investigació basat en les entrevistes i en el recull i buidatge d’articles de premsa relacionats amb el tema, durant un període de temps no gaire extens, període que correspon als tres mesos a partir dels quals s’evidencia la situació de crisi. Al mateix temps era interessant copsar l’opinió de dos grans mestres en l’estudi de l’economia del nostre país, el Dr. Fabià Estapé i el Dr. Anton Costas, mestre i deixeble respectivament.. Sense esperar massa sorpreses, la crisi actual presenta molts punts de similitud amb el procés inciat l’any 1929. Ambdós esdeveniments econòmics tenen molts punts de connexió i les mesures proposades per solucionar o per pal•liar les conseqüències són també similars. En tots dos casos la figura de l’economista britànic John Maynard Keynes és cabdal per part dels diversos governs a l’hora de reconduir i adreçar la situació econòmica.
