  2. Cholestérol alimentaire et morbi/mortalité cardiovasculaire

    2015-03-01

    Full Text Available Si l’hypercholestérolémie est un facteur de risque avéré des maladies cardiovasculaires, le rôle du cholestérol alimentaire dans la survenue de ces maladies reste discuté. À l’origine, les travaux d’Anitshkow chez le lapin ont montré qu’une alimentation riche en cholestérol se traduit par le développement de plaques d’athérome. Les études d’intervention chez l’homme ont examiné l’effet du cholestérol alimentaire et/ou des œufs sur les lipides plasmatiques, aboutissant à des résultats contradictoires. Elles ont également fait émerger la notion complexe d’hypo- et d’hyper-répondeur au cholestérol. L’épidémiologie observationnelle ne permet pas non plus de conclure à un effet délétère du cholestérol alimentaire chez l’homme. Néanmoins, chez les sujets diabétiques, une association positive entre la consommation et l’incidence des événements cardiovasculaires est retrouvée assez constamment, sans que l’on puisse l’expliquer de manière convaincante. Il n’existe pas d’essai clinique examinant l’impact des aliments riches en cholestérol sur la survenue des événements cardiovasculaires. Toutefois, les résultats des études MRFIT et PREDIMED ne vont pas dans le sens d’un effet délétère du cholestérol alimentaire. À l’inverse, les travaux réalisés sur le transporteur intestinal du cholestérol NPC1L1 sont en faveur de l’intérêt d’inhiber l’absorption du cholestérol pour réduire l’incidence des maladies cardiovasculaires. L’ensemble des données disponibles n’est pas en faveur d’un rôle clé du cholestérol alimentaire dans la survenue des maladies cardiovasculaires. Elles ne permettent donc pas d’en faire une cible prioritaire du régime à proposer pour prévenir les maladies cardiovasculaires.

    Introduction L’épaisseur intima-média de la carotide commune mesurée à l’échographie est un marqueur de risque cardio-vasculaire. L'objectif de ce travail est d’établir la corrélation entre l’épaisseur de l'intima-média carotidienne commune et les facteurs de risque cardio-vasculaire chez des sujets asymptomatiques. Méthodes Etude transversale descriptive et analytique portant sur 77 sujets de 40 ans et plus chez qui nous avons évalué les facteurs de risque cardio-vasculaire et analysé leur association avec l’épaisseur intima-média carotidienne commune. Résultats L’épaisseur intima-média augmentait avec l’âge. Les hommes avaient une épaisseur intima-média plus marquée que les femmes. L'hypertension artérielle, le diabète et la dyslipidémie sont corrélés à l’épaisseur de l'intima-média contrairement au tabagisme. Conclusion L’âge élevé et le sexe masculin sont les facteurs déterminants de la majoration de l’épaisseur intima-média carotidienne commune surtout si s'ajoutent l'hypertension artérielle, le diabète ou la dyslipidémie.

  5. Chirurgie in die Grieks-Romeinse era

    Full Text Available In die Grieks-Romeinse era het mediese behandeling kenmerkend uit drie elemente bestaan, naamlik regimen (dieet en gesonde leefwyse, geneesmiddels en chirurgie – laasgenoemde alleen toegepas indien regimen en geneesmiddels onsuksesvol was. Bewyse van primitiewe chirurgie dateer terug na die Bronstydperk, en in Homerus se eposse is heelwat vermelding van die chirurgiese hantering van oorlogswonde, met tussenkoms van die gode. Met die koms van empiriese geneeskunde in die 5de eeu v.C. het chirurgie in die Hippokratiese Corpus prominent gefigureer met beduidende bydraes in veral die ortopediese veld en hoofbeserings. Uitbouing van anatomiese en fisiologiese kennis, gebaseer op disseksie van menslike kadawers in Alexandrië vanaf die laat 4de eeu v.C., het chirurgie ’n hupstoot gegee. Teen die Romeinse era vanaf die 2de eeu v.C. het snykundetegnieke (en -instrumente beduidend verbeter, maar is steeds oorwegend deur Griekse geneeshere beoefen. Van geneeshere is steeds verwag om al drie bovermelde terapeutiese modaliteite te bemeester, maar chirurgie het meer aansien verwerf en daar is al meer in onderafdelings van chirurgie soos oogheelkunde, vrouesiektes en verloskunde, blaaskwale en mond- en keelsnykunde gespesialiseer. Militêre geneeskunde was in die Romeinse Ryk ’n belangrike aktiwiteit, en het veral traumachirurgie uitgebou. Betreding van die buik- en toraksholtes was nie meer noodwendig fataal nie, en veeartsenykunde het tot stand gekom. Die eerste beduidende chirurgiehandboek ná die Hippokratiese Corpus is in die 1ste eeu n.C. deur Celsus opgestel. Vanaf die 3de eeu het die chirurgieberoep min vordering gemaak, die beroepstaal het mettertyd van Grieks na Latyn verander en kundigheid is later veral deur Islam-geneeshere na die Middeleeue en later oorgedra.

    2004-01-01

    Full Text Available La prise alimentaire d’acides gras oméga 3 a de nombreuses conséquences biologiques en particulier dans les domaines intéressant le risque cardiovasculaire (thrombose, métabolisme lipidique, inflammation. A partir de l’énorme littérature épidémiologique sur le sujet, on peut conclure que la consommation de poisson « gras » ou d’oméga 3 à longue chaîne a un effet protecteur sur la mortalité coronaire et plus généralement sur les maladies cardiovasculaires. Il existe des indications en faveur d’un effet similaire de l’apport en alphalinolénique (ALA. Les essais de prévention secondaire avec des oméga 3 à longue chaîne ont confirmé ces résultats mais les essais de conseils nutritionnels favorisant la consommation d’ALA ne sont qu’indicatifs. Il n’existe guère « d’evidence » en faveur du rôle des oméga sur le développement quantitatif de l’athérome alors que leur effet protecteur sur la vulnérabilité cardiaque aux arythmies est bien établie. Ces données expérimentales et cliniques fournissent une base biologique à la relation observée entre un apport augmenté de poisson ou d’oméga 3 et un risque abaissé de mort subite dans plusieurs études de cohortes.

    Full Text Available Introduction : Les maladies cardiovasculaires (MCV et leurs facteurs de risque présentent des gradients socioéconomiques clairs chez les adultes canadiens, mais présentent des ambiguïtés chez les enfants. L'objectif de cette étude est de vérifier l'existence ou non de gradients socioéconomiques dans les marqueurs physiologiques du risque de MCV chez les enfants et les adolescents canadiens. Méthodologie : À partir des données transversales combinées de l'Enquête canadienne sur les mesures de la santé 2007-2011, nous avons étudié, chez 2 149 enfants (6 à 11 ans et 2 073 adolescents (12 à 17 ans et selon le sexe, les marqueurs de risque cardiovasculaire suivants : excès de poids (y compris l'obésité, score de capacité aérobique (SCA, pression artérielle (PA, lipides sanguins (totaux, cholestérol LDL et HDL, triglycérides, métabolisme du glucose et protéine C réactive (CRP. Des analyses de régression logistique et de régression linéaire multidimensionnelles ont permis de dégager les tendances relatives au risque cardiovasculaire en fonction de la suffisance du revenu du ménage et du niveau de scolarité des parents, après ajustement en fonction de l'âge et de l'origine ethnique, et après stratification par groupe d'âge et par sexe. Résultats : La prévalence de l'obésité était sensiblement plus élevée chez les jeunes garçons que chez les jeunes filles (prévalence de 18,5 %, intervalle de confiance [IC] à 95 % : 15,6 à 21,5 contre 7,7 %, IC à 95 % : 5,2 à 10,3. Toutefois, des gradients socioéconomiques négatifs ont été observés en ce qui concerne le risque d'adiposité chez les jeunes filles et les adolescentes, et non chez les garçons. Parmi les enfants et les adolescents, les garçons étaient en meilleure condition physique que les filles (SCA moyen de 541, IC à 95 % : 534 à 546 contre 501, IC à 95 % : 498 à 505 chez les enfants; 522, IC à 95 % : 514 à 529 contre 460, IC à 95 % : 454

    2007-08-01

    The history of modern plastic surgery starts when a young, restless ENT man, Dr M. Coelst, started a training in Plastic Surgery with Sebileau in Paris and Joseph in Berlin. This man of vision and far-sighted imagination realized that the separated efforts and publications of so many pioneers, scaterred all over the world, would be lost if not gathered in a scientific journal only devoted to plastic surgery for the benefit of all. This brought him to the idea of establishing, in 1931, at his own initiative, the first international Journal of Plastic Surgery ever published, the Revue de Chirurgie Plastique, fifteen years before the USA Journal Plastic and Reconstructive Surgery and sixteen years before the British Journal of Plastic Surgery. The name of the journal was changed in 1935 to the Revue de Chirurgie Structive. Coelst' Revue was promptly accepted as the leading Journal of Plastic Surgery and all the internationally known plastic Surgeons contributed to it by scientific papers of great value, even today.

    Introduction Cette étude a pour objectif de décrire la pratique anesthésique dans un pays à faible revenu et où le plateau technique anesthésique est moins équipé. Méthodes Une étude descriptive transversale a été menée durant l'année 2013. L'enquête a concerné les pratiques anesthésiques, les indications chirurgicales et les caractéristiques des malades. L'encodage et l'analyse des données ont été réalisées grâce aux logiciels Epi Info 3.5.3 et Excel 2010. Résultats Nous avons enregistré 2358 patients dont l’âge médian était de 29 + 15 ans, avec 81,5% âgés de 11 à 50 ans. Parmi eux, 67,3% des malades étaient du sexe féminin. Dans ensemble, 62,5% de ces patients étaient pris en charge pour les interventions programmées. L’évaluation du risque anesthésique a montré que 91,9% des patients étaient de la classe ASA I et II. La chirurgie la plus pratiquée était viscérale (46,7%) suivie de la chirurgie gynéco-obstétricale (29,2%). Les différents types d'anesthésie étaient les suivants: anesthésie générale (87,6%), locorégionale (11,8%) et combinée (0,6%). Conclusion La pratique anesthésique dans la population d’étude était dominée par l'anesthésie générale. Les malades étaient au trois quart de sexe féminin et de la classe ASA I et II. Les résultats de cette étude indiquent la nécessité d’évaluer l'issue de cette pratique. La pratique anesthésique à Lubumbashi est tributaire du plateau technique, des compétences du personnel et de l'acceptabilité du type d'anesthésie par les patients. PMID:26523180

    The Revue de Chirurgie Plastique and the Revue de Chirurgie Structive, Brussels (1931-1938), edited by Maurice Coelst, M.D. from Brussels, were the first, full-fledged medical publications specifically devoted to plastic, reconstructive, and aesthetic surgery. Publishing original articles by J.W. Maliniac, J. Eastman Sheehan, and brief summaries of papers read at plastic surgery societies by C.R. Straatsma, L.A. Peer, G. Aufricht, and other well-known American plastic surgeons, these Revues drew attention to surgeons, most of whom were responsible for organizing the American Society of Plastic and Reconstructive Surgeons in 1931, the same year in which the Revue de Chirurgie Plastique first appeared.

    The author emphasizes the close cooperation between U.S. plastic surgeons and the first international journal entirely devoted to plastic surgery, the Revue de Chirurgie Plastique (1931-1934) later to become the Revue de Chirurgie Structive (1935-1938) published under the editorship of Maurice Coelst, M.D. from Brussels. By the accurate recording of original articles, book reviews, proceedings of their annual meetings and summaries in three different languages (English, French, German), the author stresses the intense scientific dynamism and the achievements made by the U.S. pioneers of this new speciality, which really started during World War I.

Publishing original articles by H.D. Gillies, P.T. Kilner, A.H. McIndoe, and R. Mowlem--the "Big Four" as they were known to both English and American plastic surgeons--the Revues drew attention to these four surgeons who were mainly responsible for developing the prestige of English plastic surgery in the early 1930s.

    In 1931, Maurice Coelst, M.D. from Brussels started the publication of the first international journal of plastic surgery ever published: the Revue de Chirurgie Plastique (1931-1934), which eventually became the Revue de Chirurgie Structive (1935-1938). In 1936, he established the first European Society of Structive Surgery, which held its first congress in Brussels. Further congresses were held in London in 1937 and in Milan in 1938. It is the collaboration and the participation of British plastic surgeons in this Society, this journal, and these meetings that I want to stress, because I am firmly convinced that these documents fill a gap in the history of Plastic Surgery in Great Britain, since--as far as I know--no detailed information concerning this period was ever published in Plastic Surgery literature.

    Summary L'infection est longtemps restée la principale cause de mortalité chez le brûlé grave. Ce travail a pour but d'évaluer la prescription des antibiotiques dans notre Service des Brûlés et Chirurgie Plastique, au regard du dossier d'autorisation de mise sur le marché (Résumé des caractéristiques du produit). Tous les patients sous antibiothérapie, au Service des Brûlés et Chirurgie Plastique de l'Hôpital Militaire d'Instruction Mohammed V de Rabat, Maroc, durant la période janvier 2008/mai 2009, ont été inclus. Il s'agit d'une étude rétrospective qui a analysé 41 dossiers de patients. Les antibiotiques utilisés par le service appartiennent à différentes familles. Les plus utilisés sont les bêta-lactamines (65%), glycopeptides (10,5%), aminosides (9%), quinolones (7%) et colistine (4,3%), avec 4,2% pour les autres classes d'antibiotiques (métronidazole 500 mg en perfusion, fluconazole injectable 100 mg/50 ml, rifampicine 600 mg en perfusion, sulfadiazine argentique crème, acide fusidique 2% crème, etc.); 70% des prescriptions sont non documentées. La voie injectable est prépondérante (89%). En tout, 227 ordonnances nominatives d'antibiothérapie ont été analysées: la posologie et les contre-indications ont été respectées par rapport à l'autorisation de mise sur le marché. Trois cas d'interactions médicamenteuses ont été relevés (fluconazole-rifampicine, fluconazole-Saccharomyces boulardii, amikacine-vancomycine). Ce constat montre l'importance de l'analyse pharmaceutique des prescriptions des antibiotiques dans un service utilisant des antibiotiques de la réserve hospitalière, donc actifs mais très toxiques.

  6. Les masques de la masculinité dans le recours à la chirurgie esthétique

    Directory of Open Access Journals (Sweden)

    Michael Atkinson

    2009-10-01

    Full Text Available Depuis la fin des années 1990, un nombre croissant de Canadiens ont recours à la chirurgie esthétique comme véritable projet corporel. Un problème sociologique central émerge de ce recours massif. Pourquoi une pratique traditionnellement féminine devient-elle une pratique hautement signifiante pour ces Canadiens? La chirurgie plastique comme pratique culturelle équivaut à une mesure physique de l’évolution des pouvoirs entre les genres dans des pays comme le Canada. En outre, elle sert d’indicateur corporel de la manière dont les hommes vivent la crise actuelle de la masculinité. A la suite de Douglas (1970 ou Sontag (1991, le bouleversement normatif des corps, leurs modifications et leurs représentations publiques sont, en effet, des mesures corporelles des changements des relations de pouvoir entre hommes et femmes. Ces évolutions au Canada déstabilisent réellement les modèles de masculinité hégémonique, et sont directement observables à travers les modifications à même la peau de ces hommes. Ces recours chirurgicaux permettent de révéler les doutes, l’anxiété et l’anomie qui parsèment les cultures contemporaines. Ils redéfinissent les formes de ce travail corporel traditionnellement féminin. Il s’agit donc d’analyser comment les corps masculins modifiés par la chirurgie constituent une mesure aiguë du genre et un révélateur d’identités dans les sociétés comme le Canada.

    Full Text Available

    Introduzione: le infezioni della ferita chirurgica (Surgical Site Infection=SSI presentano nelle realtà occidentali una frequenza relativa del 15 - 20% e tassi di incidenza dal 2 - 3% al 12 - 15%, in relazione alla classe di intervento. Concorrono all’insorgenza di SSI le condizioni cliniche del paziente, la durata della degenza pre operatoria, il tipo di intervento chirurgico, le pratiche assistenziali. Lo studio di queste ultime consente di individuare e analizzare quali procedure siano adottate fra quelle definite in letteratura di provata efficacia nella prevenzione delle SSI e quali siano di uso comune pur non esistendo per esse evidenza di efficacia. Obiettivo: descrivere e analizzare le procedure di controllo delle SSI messe in atto nelle chirurgie generali degli ospedali del Piemonte sotto il profilo assistenziale e ambientale.

    Materiale e metodi: lo studio prevede una settimana di osservazione nelle sale operatorie di chirurgia generale da parte di personale formato. Saranno indagati con schede appositamente strutturate: 1 tutti gli interventi, per rilevarne le caratteristiche e le misure di controllo pre e intraoperatorie rivolte al paziente; 2 i comportamenti degli operatori in sala; 3 i dati relativi al controllo ambientale. Al fine di poter confrontare oggettivamente le diverse situazioni sarà assegnato ad ogni valutazione un punteggio, sulla base delle evidenze di efficacia disponibili.

    Risultati: i dati raccolti consentiranno di evidenziare situazioni di inosservanza delle misure di controllo efficaci, disomogeneità di comportamenti fra presidi ospedalieri o intra “team” chirurgici, di avviare interventi di correzione attraverso produzione di documenti regionali e attività di formazione mirata.

    Summary La main est fréquemment exposée aux brûlures, entraînant des séquelles esthétiques et fonctionnelles. Le traitement de ces séquelles est surtout chirurgical et consiste en la greffe de peau, dont le type dépend de la localisation de la brûlure et du type des séquelles. Dans ce travail rétrospectif, nous rapportons une série de 152 cas de brûlures des mains colligés au service de chirurgie plastique du Centre Hospitalier Universitaire Ibn-Sina de Rabat sur une période de dix ans, allant de 1998 à 2007. Les indications thérapeutiques dépendent du type de séquelles et de la localisation de la brûlure. En tout, 97 patients ont bénéficié d'une greffe cutanée, dont 76% par greffe de peau totale, 21% par greffe de peau demi-épaisse et 3% par peau fine. Les séquelles des brûlures des mains posent un problème thérapeutique majeur, malgré la diversité des procédés chirurgicaux, d'où l'intérêt de la prévention. PMID:21991196

Given that adipose tissue is abundant in majority of patients adipose derrived stem cells (ASCs have come under scrutiny for regenerative procedures in reconstructive surgery.Material and methods: ASCs were extracted by the Celution system for enrichment of fat grafts that were administered in patients with decreased wound healing, soft tissue or scar defects.Results: All patients were satisfied after reconstruction with ASCs augmented fat grafts and no side effects were observed. Discussion: The Celution system provides fast recovery of ASCs which can be immediately utilized for appropriate application. Since a high number of stem cells are harvested from fat tissue no expansion of cells is needed as described for bone marrow derived stem cells. Enrichment of fat graft with ASCs is of great interest due to their reported angiogenetic effect. The reported cases demonstrate the potential of ASCs in the field of regenerative medicine and encourage further application in reconstructive surgery.[german] Einleitung: Es konnte gezeigt werden, dass der Anteil regenerativer Zellen im Fettgewebe höher als im Knochenmark ist. Fettgewebe hingegen ist bei den meisten Patienten exzessiv vorhanden. Das legt den Einsatz von ASCs (adipose derived stem cells bei regenerativen Anwendungen in der rekonstruktiven Chirurgie nahe.Material und Methoden: Mit dem Celution System von Cytori Therapeutics Inc. prozessierte, ASC angereicherte Fetttransplantate werden an vier Patienten mit Weichteildefiziten und störenden Narben sowie Wundheilungsstörungen angewendet.Ergebnisse: Insbesondere bei Patienten mit Weichteildefiziten und Narben konnte eine suffiziente Volumenaugmentation und ansprechende Verbesserung der Narben erzielt werden.

    Full Text Available This study aims at contributing to the investigation on the instruction of EST (English for Science and Technology vocabulary, in terms of receptive use of the language. It evaluates the effectiveness of two teaching approaches to the acquisition of vocabulary. The first approach consisted of teaching vocabulary through the use of dictionaries, where the words were merely translated into the learners’ L1 or defined in the target language thus promoting superficial level of word processing. The second approach employed activities promoting deep level of word processing. Data were analysed quantitatively. Results indicated that the two approaches seem to have some equipotentiality, as far as EST vocabulary is concerned.

    Summary Les brûlures de la main chez l’enfant constituent une source de séquelles invalidantes. A cet régard, la conservation et la restauration complète de la fonction de la main demeurent le but primordial de la prise en charge. Afin de répertorier les caractéristiques épidémiologiques, cliniques et évolutives des mains brûlées, nous avons réalisé une étude rétrospective étalée sur 4 ans, de janvier 2011 à janvier 2015. Cette étude a permis de colliger les cas de 313 enfants atteints de brûlure de la main vus dans le Centre National des Brulés et de Chirurgie Plastique du CHU Ibn Rochd de Casablanca. La majorité des brûlures touche les enfants de 3 à 6 ans (70% des cas), avec une légère prédominance masculine. La principale cause des brûlures survenant à cet âge est l’ébouillantement. Les brûlures par flamme représentent 33% des cas, celles par électricité 4,5%. Les brûlures chimiques et par contact sont anecdotiques (1 cas chacune). L’accident survient le plus souvent à domicile. Soixante douze pour cent des brûlures ont guéri spontanément. Afin de diminuer l’incidence de ces accidents, une approche préventive faite de sensibilisation et d’éducation devrait faire partie du cursus scolaire. PMID:27777543

    Full Text Available In order to obtain a better understanding of what is citrus, 33 cDNA libraries were constructed from different citrus species and genera. Total RNA was extracted from fruits, leaves, flowers, bark, seeds and roots, and subjected or not to different biotic and abiotic stresses (pathogens and drought and at several developmental stages. To identify putative promoter sequences, as well as molecular markers that could be useful for breeding programs, one shotgun library was prepared from sweet orange (Citrus sinensis var. Olimpia. In addition, EST libraries were also constructed for a citrus pathogen, the oomycete Phythophthora parasitica in either virulent or avirulent form. A total of 286,559 cDNA clones from citrus were sequenced from their 5’ end, generating 242,790 valid reads of citrus. A total of 9,504 sequences were produced in the shotgun library and the valid reads were assembled using CAP3. In this procedure, we obtained 1,131 contigs and 4,083 singletons. A total of 19,200 cDNA clones from P. parasitica were sequenced, resulting in 16,400 valid reads. The number of ESTs generated in this project is, to our knowledge, the largest citrus sequence database in the world.

    2006-03-01

    Full Text Available Abstract Background EST libraries are used in various biological studies, from microarray experiments to proteomic and genetic screens. These libraries usually contain many uncharacterized ESTs that are typically ignored since they cannot be mapped to known genes. Consequently, new discoveries are possibly overlooked. Results We describe a system (EST2Prot that uses multiple elements to map EST sequences to their corresponding protein products. EST2Prot uses UniGene clusters, substring analysis, information about protein coding regions in existing DNA sequences and protein database searches to detect protein products related to a query EST sequence. Gene Ontology terms, Swiss-Prot keywords, and protein similarity data are used to map the ESTs to functional descriptors. Conclusion EST2Prot extends and significantly enriches the popular UniGene mapping by utilizing multiple relations between known biological entities. It produces a mapping between ESTs and proteins in real-time through a simple web-interface. The system is part of the Biozon database and is accessible at http://biozon.org/tools/est/.

    Schreiber, Christian; Libera, Paul; Lange, Rüdiger

    Störungen der embryonalen Entwicklung in der frühen Phase der Schwangerschaft können zu Fehlbildungen am Herz- und Gefäßsystem führen. Die Häufigkeit liegt bei 0.8-1 % aller lebend geborenen Kinder. In Deutschland werden jedes Jahr etwa 6.000 Kinder mit einem Herzfehler geboren (Quelle: http://www.kompetenznetzahf.de). Das Spektrum reicht von einfachen Fehlern, die das Herz-Kreislauf-System wenig beeinträchtigen, bis zu sehr schweren Herzerkrankungen, die unbehandelt zum Tode führen. Fortschritte der Kinderkardiologie, Herzchirurgie und Anästhesie ermöglichen heute ein Überleben bei über 90 % der Patienten. Auch die spezialisierte Pränataldiagnostik (vorgeburtliche Diagnostik) ermöglicht schon die frühe Weichenstellung für mögliche Therapieoptionen. Bei der chirurgischen Therapie ist jedoch festzuhalten, dass ein Herzfehler entweder korrigierend behandelt wird oder nur "palliiert“ werden kann. Bei letzterer Therapie wird bei einem Patienten eine medizinische Maßnahme durchgeführt, die nicht die Herstellung normaler Körperfunktionen zum Ziel hat, sondern in Anpassung an die physiologischen Besonderheiten des Patienten dessen Zustand lediglich stabilisiert und optimiert. Dies kann beispielsweise bei einer nicht korrigierbaren angeborenen Fehlbildung notwendig sein, bei der lediglich eine funktionelle Herzkammer vorhanden ist (z. B. hypoplastisches Linksherz). Hierbei muss eine prothetische Verbindung zur Lungenstrombahn in der Folgezeit entfernt werden.

  19. galaxieEST: addressing EST identity through automated phylogenetic analysis.

    Nilsson, R Henrik; Rajashekar, Balaji; Larsson, Karl-Henrik; Ursing, Björn M

    2004-07-05

    Research involving expressed sequence tags (ESTs) is intricately coupled to the existence of large, well-annotated sequence repositories. Comparatively complete and satisfactory annotated public sequence libraries are, however, available only for a limited range of organisms, rendering the absence of sequences and gene structure information a tangible problem for those working with taxa lacking an EST or genome sequencing project. Paralogous genes belonging to the same gene family but distinguished by derived characteristics are particularly prone to misidentification and erroneous annotation; high but incomplete levels of sequence similarity are typically difficult to interpret and have formed the basis of many unsubstantiated assumptions of orthology. In these cases, a phylogenetic study of the query sequence together with the most similar sequences in the database may be of great value to the identification process. In order to facilitate this laborious procedure, a project to employ automated phylogenetic analysis in the identification of ESTs was initiated. galaxieEST is an open source Perl-CGI script package designed to complement traditional similarity-based identification of EST sequences through employment of automated phylogenetic analysis. It uses a series of BLAST runs as a sieve to retrieve nucleotide and protein sequences for inclusion in neighbour joining and parsimony analyses; the output includes the BLAST output, the results of the phylogenetic analyses, and the corresponding multiple alignments. galaxieEST is available as an on-line web service for identification of fungal ESTs and for download / local installation for use with any organism group at http://galaxie.cgb.ki.se/galaxieEST.html. By addressing sequence relatedness in addition to similarity, galaxieEST provides an integrative view on EST origin and identity, which may prove particularly useful in cases where similarity searches return one or more pertinent, but not full, matches and

    Introduction L'incidence des complications respiratoires postopératoires (CRPO) reste très diversement appréciées selon les critères diagnostiques retenues dans les différentes études, ce qui la fait varier de 5 à plus de 50%. Les CRPO majeurs après chirurgie de l'aorte abdominale sont responsables d'une grande morbi-mortalité pouvant aller jusqu’à 36%, d'une durée d'hospitalisation et d'un coût plus importants. Ainsi dans l'optique d'améliorer notre prise en charge périopératoire de la chirurgie de l'aorte, nous avons décidé de mener une étude pour dresser le profil épidémiologique et déterminer les facteurs de risque des complications respiratoires dans notre contexte Méthodes Il s'agit d'une étude de cohorte rétrospective du mois de Janvier 2007 au mois de décembre 2011 portant sur l'ensemble des patients opérés pour pathologie aortique au bloc opératoire central de l'hôpital Ibn Sina de Rabat, Maroc. Résultats Cent vingt cinq patients ont été inclus dans notre étude, 24 patients ont été opérés pour anévrysme de l'aorte abdominale et 101 patients pour lésion occlusive aortoiliaque. Dans notre série 22 malades soit 17,6% ont présenté une complication respiratoire majeure avec, une reventilation dans 4,8% des cas, une difficulté de sevrage de la ventilation artificielle dans 3,2% des cas, une pneumopathie dans 4% des cas, un syndrome de détresse respiratoire aigue (SDRA) dans 4% des cas et une nécessité de fibroaspiration bronchique dans 1,6% des cas. En analyse univariée: l’âge, la présence d'une BPCO avec dyspnée stade 3 ou 4, la présence d'une anomalie à l'EFR préopératoire, la présence d'un stade avancé (III ou IV) de LOAI et la reprise chirurgicale étaient statistiquement associés à la survenue d'une complication respiratoire postopératoire. En analyse multivariée, seule une anomalie à l'EFR en préopératoire constituait un facteur de risque indépendant de survenue d'une complication

  6. PAVE: Program for assembling and viewing ESTs

    2009-08-01

    Full Text Available Abstract Background New sequencing technologies are rapidly emerging. Many laboratories are simultaneously working with the traditional Sanger ESTs and experimenting with ESTs generated by the 454 Life Science sequencers. Though Sanger ESTs have been used to generate contigs for many years, no program takes full advantage of the 5' and 3' mate-pair information, hence, many tentative transcripts are assembled into two separate contigs. The new 454 technology has the benefit of high-throughput expression profiling, but introduces time and space problems for assembling large contigs. Results The PAVE (Program for Assembling and Viewing ESTs assembler takes advantage of the 5' and 3' mate-pair information by requiring that the mate-pairs be assembled into the same contig and joined by n's if the two sub-contigs do not overlap. It handles the depth of 454 data sets by "burying" similar ESTs during assembly, which retains the expression level information while circumventing time and space problems. PAVE uses MegaBLAST for the clustering step and CAP3 for assembly, however it assembles incrementally to enforce the mate-pair constraint, bury ESTs, and reduce incorrect joins and splits. The PAVE data management system uses a MySQL database to store multiple libraries of ESTs along with their metadata; the management system allows multiple assemblies with variations on libraries and parameters. Analysis routines provide standard annotation for the contigs including a measure of differentially expressed genes across the libraries. A Java viewer program is provided for display and analysis of the results. Our results clearly show the benefit of using the PAVE assembler to explicitly use mate-pair information and bury ESTs for large contigs. Conclusion The PAVE assembler provides a software package for assembling Sanger and/or 454 ESTs. The assembly software, data management software, Java viewer and user's guide are freely available.

    2006-10-01

    Full Text Available Abstract With the decreasing cost of DNA sequencing technology and the vast diversity of biological resources, researchers increasingly face the basic challenge of annotating a larger number of expressed sequences tags (EST from a variety of species. This typically consists of a series of repetitive tasks, which should be automated and easy to use. The results of these annotation tasks need to be stored and organized in a consistent way. All these operations should be self-installing, platform independent, easy to customize and amenable to using distributed bioinformatics resources available on the Internet. In order to address these issues, we present EST-PAC a web oriented multi-platform software package for expressed sequences tag (EST annotation. EST-PAC provides a solution for the administration of EST and protein sequence annotations accessible through a web interface. Three aspects of EST annotation are automated: 1 searching local or remote biological databases for sequence similarities using Blast services, 2 predicting protein coding sequence from EST data and, 3 annotating predicted protein sequences with functional domain predictions. In practice, EST-PAC integrates the BLASTALL suite, EST-Scan2 and HMMER in a relational database system accessible through a simple web interface. EST-PAC also takes advantage of the relational database to allow consistent storage, powerful queries of results and, management of the annotation process. The system allows users to customize annotation strategies and provides an open-source data-management environment for research and education in bioinformatics.

    Introduction L’artère pudendale externe est une branche collatérale de l’artère fémorale commune qui est destinée à la vascularisation du pénis ou du clitoris. Ses rapports avec la crosse de la grande veine saphène et de ses afférences, dans le trigone fémoral, sont très étroits. Cette situation fait qu’elle est souvent lésée lors de la crossectomie et de l’éveinage de la grande veine saphène. Ces lésions peuvent être à l’origine d’une dysfonction sexuelle. Méthodes Il s’agit d’une dissection de 22 régions inguinales chez 13 hommes et 9 femmes qui ont bénéficié d’un abord chirurgical du trigone fémoral. La distribution et les rapports de l’artère pudendale externe par rapport à la crosse de la grande veine saphène sont étudiés. Résultats L’artère pudendale externe unique est la plus fréquente. Toutes les artères pudendales externes ont pour origine l’artère fémorale commune. Le rapport le plus fréquent est le sous croisement de la crosse de la grande veine saphène par une artère pudendale externe unique. Par ailleurs, on a un précroisement, un croisement alterné et des rapports avec la veine fémorale commune et des afférences de la crosse de la grande veine saphène. Certaines techniques chirurgicales exposent plus ou moins à une lésion de l’artère pudendale externe. Conclusion Ce travail confirme les données antérieures mais montre encore quelques particularités sur les rapports entre la crosse de la grande veine saphène et l’artère pudendale externe.

    Full Text Available Citrus spp. are economically important crops, which in Brazil are grown mainly in the State of São Paulo. Citrus cultures are attacked by several pathogens, causing severe yield losses. In order to better understand this culture, the Millenium Project (IAC Cordeirópolis was launched in order to sequence Citrus ESTs (expressed sequence tags from different tissues, including leaf, bark, fruit, root and flower. Plants were submitted to biotic and abiotic stresses and investigated under different development stages (adult vs. juvenile. Several cDNA libraries were constructed and the sequences obtained formed the Citrus ESTs database with almost 200,000 sequences. Searches were performed in the Citrus database to investigate the presence of different signaling pathway components. Several of the genes involved in the signaling of sugar, calcium, cytokinin, plant hormones, inositol phosphate, MAPKinase and COP9 were found in the citrus genome and are discussed in this paper. The results obtained may indicate that similar mechanisms described in other plants, such as Arabidopsis, occur in citrus. Further experimental studies must be conducted in order to understand the different signaling pathways present.

  4. Crystal structure of hyperthermophilic esterase EstE1 and the relationship between its dimerization and thermostability properties

    Full Text Available Abstract Background EstE1 is a hyperthermophilic esterase belonging to the hormone-sensitive lipase family and was originally isolated by functional screening of a metagenomic library constructed from a thermal environmental sample. Dimers and oligomers may have been evolutionally selected in thermophiles because intersubunit interactions can confer thermostability on the proteins. The molecular mechanisms of thermostabilization of this extremely thermostable esterase are not well understood due to the lack of structural information. Results Here we report for the first time the 2.1-Å resolution crystal structure of EstE1. The three-dimensional structure of EstE1 exhibits a classic α/β hydrolase fold with a central parallel-stranded beta sheet surrounded by alpha helices on both sides. The residues Ser154, Asp251, and His281 form the catalytic triad motif commonly found in other α/β hydrolases. EstE1 exists as a dimer that is formed by hydrophobic interactions and salt bridges. Circular dichroism spectroscopy and heat inactivation kinetic analysis of EstE1 mutants, which were generated by structure-based site-directed mutagenesis of amino acid residues participating in EstE1 dimerization, revealed that hydrophobic interactions through Val274 and Phe276 on the β8 strand of each monomer play a major role in the dimerization of EstE1. In contrast, the intermolecular salt bridges contribute less significantly to the dimerization and thermostability of EstE1. Conclusion Our results suggest that intermolecular hydrophobic interactions are essential for the hyperthermostability of EstE1. The molecular mechanism that allows EstE1 to endure high temperature will provide guideline for rational design of a thermostable esterase/lipase using the lipolytic enzymes showing structural similarity to EstE1.

    Full Text Available Public databases are useful for molecular marker development. The major aim of this study was to develop expressedsequence tag (EST-derived markers in Dendrobium from available ESTs of Phalaenopsis and Dendrobium. A total of 6063sequences were screened for simple sequence repeats (SSRs and introns. Primers flanking these regions were generated andtested on genomic DNAs of Phalaenopsis and Dendrobium. Twenty-three percent of amplifiable Phalaenopsis EST-derivedmarkers were cross-genera transferable to Dendrobium. Forty-one markers from both Phalaenopsis and Dendrobium thatamplified in Dendrobium were assessed on six commercial cultivars and six wild accessions. All of them were transferableamong Dendrobium species. High polymorphism and heterozygosity were observed within wild accessions. Sixteen polymorphic markers were evaluated for linkage analysis on an F1 segregating population. Seven markers were mapped into threelinkage groups, two of which showed syntenic relationship between dendrobium and rice. This relationship will facilitatefurther quantitative trait loci (QTL mapping and comparative genomic studies of Dendrobium. Our results indicate thatPhalaenopsis EST-derived markers are valuable tools for genetic research and breeding applications in Dendrobium.

    Field Punta del Este (TPE) is constituted by a series of gneisses and migmatites formed in the range of 1000 and 900 Ma, and have been intensely reworked during Rio Doce orogeny (ca. 600-500 Ma). This cortical segment represents high-grade metamorphic terrain, correlatable with complex gneiss Southwest Africa, particularly with Kibariáno Belt - Namaqualanos recognized in the southwestern portion of Africa (Namibia). U-Pb zircon ages in tonalite granitoids indicate values ​​between 1000 and 900 Ma and were interpreted as indicating the time of generation of these rocks. This should also be the age of high-grade metamorphism that affected a large part of the gneissic rocks of the region. Moreover, the anatectic related mobilized leucosomes ages of migmatites gave ca. 520-540 Ma, indicating that the metamorphic conditions (overlapping) during the Rio Doce orogeny reached at least the amphibolite facies. The metasedimentary cover TPE occurs in the vicinity of the towns of La Paloma Rocha. These are represented by a siliciclastic metasedimentary sequence represented by Rocha Formation. Despite the poly phase deformation and low grade metamorphism affecting this training, primary structures are common such as stratification plano-parallel, cross-bedding, hummock y and massive levels with gradational stratification

    Several biological techniques result in the acquisition of functional sets of cDNAs that must be sequenced and analyzed. The emergence of redundant databases such as UniGene and centralized annotation engines such as Entrez Gene has allowed the development of software that can analyze a great number of sequences in a matter of seconds. We have developed "EST Express", a suite of analytical tools that identify and annotate ESTs originating from specific mRNA populations. The software consists of a user-friendly GUI powered by PHP and MySQL that allows for online collaboration between researchers and continuity with UniGene, Entrez Gene and RefSeq. Two key features of the software include a novel, simplified Entrez Gene parser and tools to manage cDNA library sequencing projects. We have tested the software on a large data set (2,016 samples) produced by subtractive hybridization. EST Express is an open-source, cross-platform web server application that imports sequences from cDNA libraries, such as those generated through subtractive hybridization or yeast two-hybrid screens. It then provides several layers of annotation based on Entrez Gene and RefSeq to allow the user to highlight useful genes and manage cDNA library projects.

    Full Text Available Mapping expressed sequence tags (ESTs to hexaploid wheat is aimed to reveal the structure and function of the hexaploid wheat genome. Sixty eight ESTs representing 26 genes were mapped into all seven homologous chromosome groups of wheat (Triticum aestivum L using a polymerase chain reaction technique. The majority of the ESTs were mapped to homologous chromosome group 2, and the least were mapped to homologous chromosome group 6. Comparative analysis between the EST map from this study and the EST map based on RFLPs showed 14 genes that have been mapped by both approaches were mapped to the same arm of the same homologous chromosome, which indicated that using PCR-based ESTs was a reliable approach in mapping ESTs in hexaploid wheat.

    Full Text Available Abstract Background With the advent of low-cost, high-throughput sequencing, the amount of public domain Expressed Sequence Tag (EST sequence data available for both model and non-model organism is growing exponentially. While these data are widely used for characterizing various genomes, they also present a serious challenge for data quality control and validation due to their inherent deficiencies, particularly for species without genome sequences. Description ConiferEST is an integrated system for data reprocessing, visualization and mining of conifer ESTs. In its current release, Build 1.0, it houses 172,229 loblolly pine EST sequence reads, which were obtained from reprocessing raw DNA sequencer traces using our software – WebTraceMiner. The trace files were downloaded from NCBI Trace Archive. ConiferEST provides biologists unique, easy-to-use data visualization and mining tools for a variety of putative sequence features including cloning vector segments, adapter sequences, restriction endonuclease recognition sites, polyA and polyT runs, and their corresponding Phred quality values. Based on these putative features, verified sequence features such as 3' and/or 5' termini of cDNA inserts in either sense or non-sense strand have been identified in-silico. Interestingly, only 30.03% of the designated 3' ESTs were found to have an authenticated 5' terminus in the non-sense strand (i.e., polyT tails, while fewer than 5.34% of the designated 5' ESTs had a verified 5' terminus in the sense strand. Such previously ignored features provide valuable insight for data quality control and validation of error-prone ESTs, as well as the ability to identify novel functional motifs embedded in large EST datasets. We found that "double-termini adapters" were effective indicators of potential EST chimeras. For all sequences with in-silico verified termini/terminus, we used InterProScan to assign protein domain signatures, results of which are available

    Full Text Available Podemos comunicarlo todo: tenemos las tecnologías de la comunicación cada vez más cerca; pero no podemos contar nada, porque no tenemos nada qué decir, ni sabemos cómo decirlo. Hay que inventarlo todo, intervenir de nuevo la sociedad desde la comunicación. Es necesario convertir los medios en experiencia estética, social y política. ¿Cómo? Usando a las tecnologías para el activismo y el experimento; recurriendo a los llamado retro, porque no es lo más actual, lo más mercado, como experiencia de inspiración y emoción. Hay que volver a las estéticas, a los modos de narrar y a las historias que están inscritas en nuestras identidades locales; en nuestras sensibilidades femeninas, juveniles o sexuales; en nuestras tradiciones étnicas, o en nuestros modos urbanos. Sólo basta una minicámara para inventar el universo. En este ensayo se realiza un alegato contra los universos estético-narrativopolíticos construidos por la máquina televisiva y la homogeneidad del mercado. En este texto se argumenta a favor del activismo comunicativo, de la exploración tecnológica y de la inspiración étnica como estrategias para generar una mayor conciencia sobre el valor social de la comunicación, la intervención estético-narrativa de la sociedad y la importancia política de los medios de la gente.

    Full Text Available El legado filosófico que nos ha dejado Rodolfo Kusch tiene cada vez más presencia y valor en este largo itinerario de descubrirnos como americanos. La pasión de este pensador por la América profunda es una fuente de ins- piración para quienes creemos que vivir en América no es simplemente un episodio geográfico sino un horizonte desde y a partir del cual construimos nuestra identidad. En este trabajo se pretende recrear sus consideracio - nes estéticas recogidas en su ensayo “Anotaciones para una estética de lo americano”, escrito en el año 1955. Aunque se trata de uno de los primeros escritos de Rodolfo Kusch, en el mismo se encuentran presentes numerosos conceptos que luego serán tematizados extensamente a lo largo de toda su obra. Considero que el abordaje a sus consideraciones estéticas no ha sido tan frecuentado como sí otros aspectos de su pensamiento (ser-estar, geocultura, símbolo y religión, etc.. Por ello, creo que este trabajo puede constituir una orientación preeliminar para futuras interpretaciones y, a la vez, ser un humilde homenaje a su filosofía, que, a lo largo de los años, sigue estimulando a antiguas y nuevas generaciones de pensadores dedicados a la filosofía latinoamericana.

    2006-06-01

    Full Text Available Abstract Background Wheat is an excellent species to study freezing tolerance and other abiotic stresses. However, the sequence of the wheat genome has not been completely characterized due to its complexity and large size. To circumvent this obstacle and identify genes involved in cold acclimation and associated stresses, a large scale EST sequencing approach was undertaken by the Functional Genomics of Abiotic Stress (FGAS project. Results We generated 73,521 quality-filtered ESTs from eleven cDNA libraries constructed from wheat plants exposed to various abiotic stresses and at different developmental stages. In addition, 196,041 ESTs for which tracefiles were available from the National Science Foundation wheat EST sequencing program and DuPont were also quality-filtered and used in the analysis. Clustering of the combined ESTs with d2_cluster and TGICL yielded a few large clusters containing several thousand ESTs that were refractory to routine clustering techniques. To resolve this problem, the sequence proximity and "bridges" were identified by an e-value distance graph to manually break clusters into smaller groups. Assembly of the resolved ESTs generated a 75,488 unique sequence set (31,580 contigs and 43,908 singletons/singlets. Digital expression analyses indicated that the FGAS dataset is enriched in stress-regulated genes compared to the other public datasets. Over 43% of the unique sequence set was annotated and classified into functional categories according to Gene Ontology. Conclusion We have annotated 29,556 different sequences, an almost 5-fold increase in annotated sequences compared to the available wheat public databases. Digital expression analysis combined with gene annotation helped in the identification of several pathways associated with abiotic stress. The genomic resources and knowledge developed by this project will contribute to a better understanding of the different mechanisms that govern stress tolerance in

Con Arendt sostengo que este fenómeno no está superado, porque el odio es la herramienta que despliega el Capital, para amalgamar a todos los desheredados que ha creado. Contextualizo en la práctica artística colombiana el siguiente argumento de Arendt: el capitalismo creó una amalgama de frustrados sociales, políticos y estéticos que destruye la esfera pública como lugar para el acontecer de la política, amalgama que denominó populacho. Introduzco la categoría de populacho estético, para hablar del odio que ha animado las prácticas artísticas en Colombia desde 1940.

    Coevolution of cellular genetic compartments is a fundamental aspect in eukaryotic genome evolution that becomes apparent in serious developmental disturbances after interspecific organelle exchanges. The genus Oenothera represents a unique, at present the only available, resource to study the role of the compartmentalized plant genome in diversification of populations and speciation processes. An integrated approach involving cDNA cloning, EST sequencing, and bioinformatic data mining was chosen using Oenothera elata with the genetic constitution nuclear genome AA with plastome type I. The Gene Ontology system grouped 1621 unique gene products into 17 different functional categories. Application of arrays generated from a selected fraction of ESTs revealed significantly differing expression profiles among closely related Oenothera species possessing the potential to generate fertile and incompatible plastid/nuclear hybrids (hybrid bleaching). Furthermore, the EST library provides a valuable source of PCR-based polymorphic molecular markers that are instrumental for genotyping and molecular mapping approaches.

    Full Text Available Abstract Background The castor bean (Ricinus communis L., a monotypic species in the spurge family (Euphorbiaceae, 2n = 20, is an important non-edible oilseed crop widely cultivated in tropical, sub-tropical and temperate countries for its high economic value. Because of the high level of ricinoleic acid (over 85% in its seed oil, the castor bean seed derivatives are often used in aviation oil, lubricants, nylon, dyes, inks, soaps, adhesive and biodiesel. Due to lack of efficient molecular markers, little is known about the population genetic diversity and the genetic relationships among castor bean germplasm. Efficient and robust molecular markers are increasingly needed for breeding and improving varieties in castor bean. The advent of modern genomics has produced large amounts of publicly available DNA sequence data. In particular, expressed sequence tags (ESTs provide valuable resources to develop gene-associated SSR markers. Results In total, 18,928 publicly available non-redundant castor bean EST sequences, representing approximately 17.03 Mb, were evaluated and 7732 SSR sites in 5,122 ESTs were identified by data mining. Castor bean exhibited considerably high frequency of EST-SSRs. We developed and characterized 118 polymorphic EST-SSR markers from 379 primer pairs flanking repeats by screening 24 castor bean samples collected from different countries. A total of 350 alleles were identified from 118 polymorphic SSR loci, ranging from 2-6 per locus (A with an average of 2.97. The EST-SSR markers developed displayed moderate gene diversity (He with an average of 0.41. Genetic relationships among 24 germplasms were investigated using the genotypes of 350 alleles, showing geographic pattern of genotypes across genetic diversity centers of castor bean. Conclusion Castor bean EST sequences exhibited considerably high frequency of SSR sites, and were rich resources for developing EST-SSR markers. These EST-SSR markers would be particularly

    Expressed sequence tag (EST) markers have been used to assess variety and genetic diversity in wheat (Triticum aestivum). In this study, 1549 ESTs from wheat infested with yellow rust were used to examine the genetic diversity of six susceptible and resistant wheat cultivars. The aim of using these cultivars was to improve the competitiveness of public wheat breeding programs through the intensive use of modern, particularly marker-assisted, selection technologies. The F(2) individuals derived from cultivar crosses were screened for resistance to yellow rust at the seedling stage in greenhouses and adult stage in the field to identify DNA markers genetically linked to resistance. Five hundred and sixty ESTs were assembled into 136 contigs and 989 singletons. BlastX search results showed that 39 (29%) contigs and 96 (10%) singletons were homologous to wheat genes. The database-matched contigs and singletons were assigned to eight functional groups related to protein synthesis, photosynthesis, metabolism and energy, stress proteins, transporter proteins, protein breakdown and recycling, cell growth and division and reactive oxygen scavengers. PCR analyses with primers based on the contigs and singletons showed that the most polymorphic functional categories were photosynthesis (contigs) and metabolism and energy (singletons). EST analysis revealed considerable genetic variability among the Turkish wheat cultivars resistant and susceptible to yellow rust disease and allowed calculation of the mean genetic distance between cultivars, with the greatest similarity (0.725) being between Harmankaya99 and Sönmez2001, and the lowest (0.622) between Aytin98 and Izgi01.

    Full Text Available The fluoride has volcanic activity and abundantly exists in environment combining with other elements as fluoride compounds. Recent researches indicated that the molecular mechanisms of intracellular fluoride toxicity were very complex. However, the molecular mechanisms underlying the effects on gene expression of chronic fluoride-induced damage is unknown, especially the detailed regulatory process of mitochondria. In the present study, we screened the differential expression ESTs associated with fluorosis by DDRT-PCR in rat liver. We gained 8 genes, 3 new ESTs, and 1 unknown function sequence and firstly demonstrated that microsomal glutathione S-transferase 1 (MGST1, ATP synthase H+ transporting mitochondrial F0 complex subunit C1, selenoprotein S, mitochondrial IF1 protein, and mitochondrial succinyl-CoA synthetase alpha subunit were participated in mitochondria metabolism, functional and structural damage process caused by chronic fluorosis. This information will be very helpful for understanding the molecular mechanisms of fluorosis.

Para ello, toda revisión se apoyó en las ideas de Jean Piaget (2010/1946, 1994/1932, quien elaboró una teoría sobre el juego. Dichos conocimientos sirvieron para la comprensión de que los maestros no están preparados para este tipo de actividad didáctico-pedagógica, pues dicha educación es un proceso que demanda toma de conciencia de propia praxis, la cual requiere el (re aprendizaje a respecto de los objetivos de diferentes tipos de juegos y del desarrollo infantil, siendo que ello necesita ocurrir en la formación inicial y en la formación continua de profesores.

    Full Text Available Abstract Background Salmonids are of interest because of their relatively recent genome duplication, and their extensive use in wild fisheries and aquaculture. A comprehensive gene list and a comparison of genes in some of the different species provide valuable genomic information for one of the most widely studied groups of fish. Results 298,304 expressed sequence tags (ESTs from Atlantic salmon (69% of the total, 11,664 chinook, 10,813 sockeye, 10,051 brook trout, 10,975 grayling, 8,630 lake whitefish, and 3,624 northern pike ESTs were obtained in this study and have been deposited into the public databases. Contigs were built and putative full-length Atlantic salmon clones have been identified. A database containing ESTs, assemblies, consensus sequences, open reading frames, gene predictions and putative annotation is available. The overall similarity between Atlantic salmon ESTs and those of rainbow trout, chinook, sockeye, brook trout, grayling, lake whitefish, northern pike and rainbow smelt is 93.4, 94.2, 94.6, 94.4, 92.5, 91.7, 89.6, and 86.2% respectively. An analysis of 78 transcript sets show Salmo as a sister group to Oncorhynchus and Salvelinus within Salmoninae, and Thymallinae as a sister group to Salmoninae and Coregoninae within Salmonidae. Extensive gene duplication is consistent with a genome duplication in the common ancestor of salmonids. Using all of the available EST data, a new expanded salmonid cDNA microarray of 32,000 features was created. Cross-species hybridizations to this cDNA microarray indicate that this resource will be useful for studies of all 68 salmonid species. Conclusion An extensive collection and analysis of salmonid RNA putative transcripts indicate that Pacific salmon, Atlantic salmon and charr are 94–96% similar while the more distant whitefish, grayling, pike and smelt are 93, 92, 89 and 86% similar to salmon. The salmonid transcriptome reveals a complex history of gene duplication that is

    Full Text Available DNA repair pathways are necessary to maintain the proper genomic stability and ensure the survival of the organism, protecting it against the damaging effects of endogenous and exogenous agents. In this work, we made an analysis of the expression patterns of DNA repair-related genes in sugarcane, by determining the EST (expressed sequence tags distribution in the different cDNA libraries of the SUCEST transcriptome project. Three different pathways - photoreactivation, base excision repair and nucleotide excision repair - were investigated by employing known DNA repair proteins as probes to identify homologous ESTs in sugarcane, by means of computer similarity search. The results showed that DNA repair genes may have differential expressions in tissues, depending on the pathway studied. These in silico data provide important clues on the potential variation of gene expression, to be confirmed by direct biochemical analysis.As vias de reparo de DNA são requeridas para manter a necessária estabilidade genômica e garantir a sobrevivência do organismo, frente aos efeitos deletérios causados por fatores endógenos e exógenos. Neste trabalho, realizamos a análise dos padrões de expressão dos genes de reparo de DNA encontrados na cana-de-açúcar, pela determinação da distribuição de ESTs nas diferentes bibliotecas de cDNA no projeto de transcriptoma SUCEST. Três vias de reparo - fotorreativação, reparo por excisão de bases e reparo por excisão de nucleotídeos - foram estudadas através do uso de proteínas de reparo como sondas para identificação de ESTs homólogos em cana-de-açúcar, com base na procura computacional de similaridade. Os resultados indicam que os genes de reparo de DNA possuem uma expressão diferencial nos tecidos, dependendo da via de reparo analisada. Esses dados in silico fornecem importantes indícios da expressão diferencial, a qual deve ser confirmada por análises bioquímicas diretas.

  1. Upgrading Unconventional Oil Resources with the EST Process

    Energy Technology Data Exchange (ETDEWEB)

    2007-07-01

    We strongly believe that unconventional oils will play a much larger role in the growth of supply than is currently recognized. As a matter of fact, whereas the earth's conventional proven world oil reserves are 1.3 trillion barrels, extra-heavy plus bitumen resources amount to about 4 trillion barrels. The unconventional oils are characterized by low API gravity (<10), high viscosity and high concentration of poisons such as sulphur, nitrogen, metals, and asphaltenes. For this reason, a key role for the full exploitation of these hydrocarbon resources is played by the downstream processes that are required to upgrade and convert them into valuable products. In this scenario, Eni has developed a novel hydrocracking process (EST: Eni Slurry Technology) which is particularly well-suited for the conversion and upgrading of heavy feedstocks (conventional vacuum residues, extra-heavy oils and bitumen). EST employs nano-sized hydrogenation catalysts and an original process scheme that allow complete feedstock conversion to an upgraded synthetic crude oil (SCO) with an API gravity gain greater than 20 and avoid the production of residual by-products, such as pet-coke or heavy fuel oil. A Commercial Demonstration Unit (CDP) of 1200 bbl/d capacity is successfully operating in the Eni's Taranto refinery since November 2005. (auth)

Over the course of the colonial experience, tension infuses the discourse and problems in the use of classicist motifs as imperial models of appropriation become apparent: metaphoric and metonymic references collide; positive and negative connotations overlap; incompatible modes of temporalization contrast with one another; colonial and dissident identifications coincide. The concept of "antiquity" is de-authorized, deconstructed. Readers witness the dissolution of European classicism as a politico-aesthetic 'dispositif' due to the experience of cultural difference.

    Full Text Available Abstract Background Coral reef ecosystems are renowned for their diversity and beauty. Their immense ecological success is due to a symbiotic association between cnidarian hosts and unicellular dinoflagellate algae, known as zooxanthellae. These algae are photosynthetic and the cnidarian-zooxanthellae association is based on nutritional exchanges. Maintenance of such an intimate cellular partnership involves many crosstalks between the partners. To better characterize symbiotic relationships between a cnidarian host and its dinoflagellate symbionts, we conducted a large-scale EST study on a symbiotic sea anemone, Anemonia viridis, in which the two tissue layers (epiderm and gastroderm can be easily separated. Results A single cDNA library was constructed from symbiotic tissue of sea anemones A. viridis in various environmental conditions (both normal and stressed. We generated 39,939 high quality ESTs, which were assembled into 14,504 unique sequences (UniSeqs. Sequences were analysed and sorted according to their putative origin (animal, algal or bacterial.

    Full Text Available It is quite clear that there is a canonical foundation underlying the institute of transactio. Indeed, a compromise is often reached when a dispute has already entered the litigation phase, and as such legal doctrine tends to separate the economic aspect from the ethical aspect in its interpretation. Though the Church has a necessarily imperfect system of legal sanctions at its disposal, over the centuries it has in fact played a fundamental role in the ethical aspect of compromise. Indeed, the Gospel teaches that every human relationship must be based on concordia, as concordia mater est unitatis: if parties have ignored such morals and are about to litigate, or have already started legal proceedings, the Church must exhort them to settle the dispute. This article aims to examine the relevance of two of the essential requirements of transactio –namely lis and res dubia – within the Decretals (X 1.36. 1-11 de transactionibus. The framework of this analysis is provided by the tenet Effectus transactionis est, ut ei stetur, which sanctions the effectiveness of transactio as a juristic act. The goal is to evaluate how the uncertainty of legal proceedings relates to the principle of good faith in canon law.

    The European Solar Telescope (EST) is a European collaborative project to build a 4m class solar telescope in the Canary Islands, which is now in its design study phase. The telescope will provide diffraction limited performance for several instruments observing simultaneously at the Coudé focus at different wavelengths. A multi-conjugated adaptive optics system composed of a tip-tilt mirror and several deformable mirrors will be integrated in the telescope optical path. The secondary mirror system is composed of the mirror itself (Ø800mm), the alignment drives and the cooling system needed to remove the solar heat load from the mirror. During the design study the feasibility to provide fast tip-tilt capabilities at the secondary mirror to work as the adaptive optics tip-tilt mirror is also being evaluated.

    2010-01-01

    Hormone sensitive lipase (HSL) plays a major role in energy homeostasis and lipid metabolism. Several crystal structures of HSL-homolog proteins have been identified, which has led to a better understanding of its molecular function. HSLhomolog proteins exit as both monomer and dimer, but the biochemical and structural basis for such oligomeric states has not been successfully elucidated. Therefore, we determined the crystal structure of HSL-homolog protein EstE7 from a metagenome library at 2.2 A resolution and characterized the oligomeric states of EstE7 both structurally and biochemically. EstE7 protein prefers the dimeric state in solution, which is supported by its higher enzymatic activity in the dimeric state. In the crystal form, EstE7 protein shows two-types of dimeric interface. Specifically, dimerization via the external β8-strand occurred through tight association between two pseudosymmetric folds via salt bridges, hydrogen bonds and van der Waals interactions. This dimer formation was similar to that of other HSL-homolog protein structures such as AFEST, BEFA, and EstE1. We anticipate that our results will provide insight into the oligomeric state of HSLhomolog proteins

  14. Putative resistance genes in the CitEST database

    Full Text Available Disease resistance in plants is usually associated with the activation of a wide variety of defense responses to prevent pathogen replication and/or movement. The ability of the host plant to recognize the pathogen and to activate defense responses is regulated by direct or indirect interaction between the products of plant resistance (R and pathogen avirulence (Avr genes. Attempted infection of plants by avirulent pathogens elicits a battery of defenses often followed by the collapse of the challenged host cells. Localized host cell death may help to prevent the pathogen from spreading to uninfected tissues, known as hypersensitive response (HR. When either the plant or the pathogen lacks its cognate gene, activation of the plant’s defense responses fails to occur or is delayed and does not prevent pathogen colonization. In the CitEST database, we identified 1,300 reads related to R genes in Citrus which have been reported in other plant species. These reads were translated in silico, and alignments of their amino acid sequences revealed the presence of characteristic domains and motifs that are specific to R gene classes. The description of the reads identified suggests that they function as resistance genes in citrus.

    Directory of Open Access Journals (Sweden)

    Renato Bittencourt

    2010-07-01

    Full Text Available A proposta deste artigo consiste em pensarmos a relação intrínseca que Nietzsche estabelece entre a estética e a compreensão orgânica da vida humana, associada diretamente a uma perspectiva fisiológica. Cabe ressaltar que a noção de fisiologia em Nietzsche não se fundamenta em parâmetros puramente biológicos ou materiais, mas envolve todos os atos criativos do indivíduo. Por conseguinte, para compreendermos de forma precisa a realização da criatividade artística é de suma importância que se faça valer a importância da fisiologia do artista no processo de elaboração da obra de arte. Onde os instintos vitais se encontram em declínio existencial, haverá uma obra de arte decadente; onde os instintos vitais manifestam exuberância, capacidade de assimilação e saúde, haverá uma glorificação da existência através da arte.

    2008-12-01

    Full Text Available Abstract Background The metazoan taxon Syndermata comprising Rotifera (in the classical sense of Monogononta+Bdelloidea+Seisonidea and Acanthocephala has raised several hypotheses connected to the phylogeny of these animal groups and the included subtaxa. While the monophyletic origin of Syndermata and Acanthocephala is well established based on morphological and molecular data, the phylogenetic position of Syndermata within Spiralia, the monophyletic origin of Monogononta, Bdelloidea, and Seisonidea and the acanthocephalan sister group are still a matter of debate. The comparison of the alternative hypotheses suggests that testing the phylogenetic validity of Eurotatoria (Monogononta+Bdelloidea is the key to unravel the phylogenetic relations within Syndermata. The syndermatan phylogeny in turn is a prerequisite for reconstructing the evolution of the acanthocephalan endoparasitism. Results Here we present our results from a phylogenomic approach studying i the phylogenetic position of Syndermata within Spiralia, ii the monophyletic origin of monogononts and bdelloids and iii the phylogenetic relations of the latter two taxa to acanthocephalans. For this analysis we have generated EST libraries of Pomphorhynchus laevis, Echinorhynchus truttae (Acanthocephala and Brachionus plicatilis (Monogononta. By extending these data with database entries of B. plicatilis, Philodina roseola (Bdelloidea and 25 additional metazoan species, we conducted phylogenetic reconstructions based on 79 ribosomal proteins using maximum likelihood and bayesian approaches. Our findings suggest that the phylogenetic position of Syndermata within Spiralia is close to Platyhelminthes, that Eurotatoria are not monophyletic and that bdelloids are more closely related to acanthocephalans than monogononts. Conclusion Mapping morphological character evolution onto molecular phylogeny suggests the (partial or complete reduction of the corona and the emergence of a retractable

    2009-10-01

    Full Text Available Abstract Background The origin of novel traits and their subsequent diversification represent central themes in evo-devo and evolutionary ecology. Here we explore the genetic and genomic basis of a class of traits that is both novel and highly diverse, in a group of organisms that is ecologically complex and experimentally tractable: horned beetles. Results We developed two high quality, normalized cDNA libraries for larval and pupal Onthophagus taurus and sequenced 3,488 ESTs that assembled into 451 contigs and 2,330 singletons. We present the annotation and a comparative analysis of the conservation of the sequences. Microarrays developed from the combined libraries were then used to contrast the transcriptome of developing primordia of head horns, prothoracic horns, and legs. Our experiments identify a first comprehensive list of candidate genes for the evolution and diversification of beetle horns. We find that developing horns and legs show many similarities as well as important differences in their transcription profiles, suggesting that the origin of horns was mediated partly, but not entirely, by the recruitment of genes involved in the formation of more traditional appendages such as legs. Furthermore, we find that horns developing from the head and prothorax differ in their transcription profiles to a degree that suggests that head and prothoracic horns are not serial homologs, but instead may have evolved independently from each other. Conclusion We have laid the foundation for a systematic analysis of the genetic basis of horned beetle development and diversification with the potential to contribute significantly to several major frontiers in evolutionary developmental biology.

    The "living fossil" Metasequoia glyptostroboides Hu et Cheng, commonly known as dawn redwood or Chinese redwood, is the only living species in the genus and is valued for its essential oil and crude extracts that have great potential for anti-fungal activity. Despite its paleontological significance and economical value as a rare relict species, genomic resources of Metasequoia are very limited. In order to gain insight into the molecular mechanisms behind the formation of reproductive buds and the transition from vegetative phase to reproductive phase in Metasequoia, we performed sequencing of expressed sequence tags from Metasequoia vegetative buds and female buds. By using the 454 pyrosequencing technology, a total of 1,571,764 high-quality reads were generated, among which 733,128 were from vegetative buds and 775,636 were from female buds. These EST reads were clustered and assembled into 114,124 putative unique transcripts (PUTs) with an average length of 536 bp. The 97,565 PUTs that were at least 100 bp in length were functionally annotated by a similarity search against public databases and assigned with Gene Ontology (GO) terms. A total of 59 known floral gene families and 190 isotigs involved in hormone regulation were captured in the dataset. Furthermore, a set of PUTs differentially expressed in vegetative and reproductive buds, as well as SSR motifs and high confidence SNPs, were identified.

    Full Text Available Abstract Background There is no dedicated database available for Expressed Sequence Tags (EST of the chili pepper (Capsicum annuum, although the interest in a chili pepper EST database is increasing internationally due to the nutritional, economic, and pharmaceutical value of the plant. Recent advances in high-throughput sequencing of the ESTs of chili pepper cv. Bukang have produced hundreds of thousands of complementary DNA (cDNA sequences. Therefore, a chili pepper EST database was designed and constructed to enable comprehensive analysis of chili pepper gene expression in response to biotic and abiotic stresses. Results We built the Pepper EST database to mine the complexity of chili pepper ESTs. The database was built on 122,582 sequenced ESTs and 116,412 refined ESTs from 21 pepper EST libraries. The ESTs were clustered and assembled into virtual consensus cDNAs and the cDNAs were assigned to metabolic pathway, Gene Ontology (GO, and MIPS Functional Catalogue (FunCat. The Pepper EST database is designed to provide a workbench for (i identifying unigenes in pepper plants, (ii analyzing expression patterns in different developmental tissues and under conditions of stress, and (iii comparing the ESTs with those of other members of the Solanaceae family. The Pepper EST database is freely available at http://genepool.kribb.re.kr/pepper/. Conclusion The Pepper EST database is expected to provide a high-quality resource, which will contribute to gaining a systemic understanding of plant diseases and facilitate genetics-based population studies. The database is also expected to contribute to analysis of gene synteny as part of the chili pepper sequencing project by mapping ESTs to the genome.

    Recombinant EstE1 protein with a histidine tag at the C-terminus was overexpressed in Escherichia coli strain BL21(DE3) and then purified by affinity chromatography. The protein was then crystallized at 290 K by the hanging-drop vapour-diffusion method. EstE1, a new thermostable esterase, was isolated by functional screening of a metagenomic DNA library from thermal environment samples. This enzyme showed activity towards short-chain acyl derivatives of length C4–C6 at a temperature of 303–363 K and displayed a high thermostability above 353 K. EstE1 has 64 and 57% amino-acid sequence similarity to est{sub pc}-encoded carboxylesterase from Pyrobaculum calidifontis and AFEST from Archaeoglobus fulgidus, respectively. The recombinant protein with a histidine tag at the C-terminus was overexpressed in Escherichia coli strain BL21(DE3) and then purified by affinity chromatography. The protein was crystallized at 290 K by the hanging-drop vapour-diffusion method. X-ray diffraction data were collected to 2.3 Å resolution from an EstE1 crystal; the crystal belongs to space group P4{sub 1}2{sub 1}2, with unit-cell parameters a = b = 73.71, c = 234.23 Å. Assuming the presence of four molecules in the asymmetric unit, the Matthews coefficient V{sub M} is calculated to be 2.2 Å{sup 3} Da{sup −1} and the solvent content is 44.1%.

    Full Text Available Este artículo describe la experiencia estética como un fenómeno centrado en la percepción sensorial. El trabajo se desarrolla a partir de una investigación de la psicología social basado en la fenomenología, sobre todo en los planteamientos de Merleau-Ponty y Dufrenne. Concibe la experiencia estética como un modo de relación mediada por la percepción sensorial de un objeto estético. Se analizan diversos aspectos de la experiencia estética: la dimensión relacional y sensible; ¿cómo se constituye el sujeto y el objeto estético; la dimensión corporal de la experiencia estética; la intencionalidad en la estética; la experiencia estética de la naturaleza. Llegamos a la conclusión de que hay un significado ontológico de la experiencia estética, ya que proporciona una apertura a la diferencia por el contacto con la alteridad, y una nueva mirada a la realidad. Se destaca al final la relevancia de esta experiencia a la Psicología Social.

    Lanfranchi Gerolamo

    2002-10-01

    Full Text Available Abstract Background We describe the development, validation, and use of a highly redundant 120,000 oligonucleotide microarray (MuscleChip containing 4,601 probe sets representing 1,150 known genes expressed in muscle and 2,075 EST clusters from a non-normalized subtracted muscle EST sequencing project (28,074 EST sequences. This set included 369 novel EST clusters showing no match to previously characterized proteins in any database. Each probe set was designed to contain 20–32 25 mer oligonucleotides (10–16 paired perfect match and mismatch probe pairs per gene, with each probe evaluated for hybridization kinetics (Tm and similarity to other sequences. The 120,000 oligonucleotides were synthesized by photolithography and light-activated chemistry on each microarray. Results Hybridization of human muscle cRNAs to this MuscleChip (33 samples showed a correlation of 0.6 between the number of ESTs sequenced in each cluster and hybridization intensity. Out of 369 novel EST clusters not showing any similarity to previously characterized proteins, we focused on 250 EST clusters that were represented by robust probe sets on the MuscleChip fulfilling all stringent rules. 102 (41% were found to be consistently "present" by analysis of hybridization to human muscle RNA, of which 40 ESTs (39% could be genome anchored to potential transcription units in the human genome sequence. 19 ESTs of the 40 ESTs were furthermore computer-predicted as exons by one or more than three gene identification algorithms. Conclusion Our analysis found 40 transcriptionally validated, genome-anchored novel EST clusters to be expressed in human muscle. As most of these ESTs were low copy clusters (duplex and triplex in the original 28,000 EST project, the identification of these as significantly expressed is a robust validation of the transcript units that permits subsequent focus on the novel proteins encoded by these genes.

    Simple sequence repeats (SSRs) have become widely used as molecular markers in plant genetic studies due to their abundance, high allelic variation at each locus and simplicity to analyze using conventional PCR amplification. To study plants with unknown genome sequence, SSR markers from Expressed Sequence Tags (ESTs), which can be obtained from the plant mRNA (converted to cDNA), must be utilized. With the advent of high-throughput sequencing technology, huge EST sequence data have been generated and are now accessible from many public databases. However, SSR marker identification from a large in-house or public EST collection requires a computational pipeline that makes use of several standard bioinformatic tools to design high quality EST-SSR primers. Some of these computational tools are not users friendly and must be tightly integrated with reference genomic databases. A web-based bioinformatic pipeline, called EST Analysis Pipeline Plus (ESAP Plus), was constructed for assisting researchers to develop SSR markers from a large EST collection. ESAP Plus incorporates several bioinformatic scripts and some useful standard software tools necessary for the four main procedures of EST-SSR marker development, namely 1) pre-processing, 2) clustering and assembly, 3) SSR mining and 4) SSR primer design. The proposed pipeline also provides two alternative steps for reducing EST redundancy and identifying SSR loci. Using public sugarcane ESTs, ESAP Plus automatically executed the aforementioned computational pipeline via a simple web user interface, which was implemented using standard PHP, HTML, CSS and Java scripts. With ESAP Plus, users can upload raw EST data and choose various filtering options and parameters to analyze each of the four main procedures through this web interface. All input EST data and their predicted SSR results will be stored in the ESAP Plus MySQL database. Users will be notified via e-mail when the automatic process is completed and they can

    Expressed sequence tags (ESTs) are short single-pass DNA sequences obtained from either end of cDNA clones. These ESTs are derived from a vast number of cDNA libraries obtained from different species. Human ESTs are the bulk of the data and have been widely used to identify new members of gene families, as markers on the human chromosomes, to discover polymorphism sites and to compare expression patterns in different tissues or pathologies states. Information strategies have been devised to query EST databases. Since most of the analysis is performed with a computer, the term "in silico" strategy has been coined. In this chapter we will review the current status of EST databases, the pros and cons of EST-type data and describe possible strategies to retrieve meaningful information.

    Full Text Available Abstract Background Single-pass, partial sequencing of complementary DNA (cDNA libraries generates thousands of chromatograms that are processed into high quality expressed sequence tags (ESTs, and then assembled into contigs representative of putative genes. Usually, to be of value, ESTs and contigs must be associated with meaningful annotations, and made available to end-users. Results A web application, Expressed Sequence Tag Information Management and Annotation (ESTIMA, has been created to meet the EST annotation and data management requirements of multiple high-throughput EST sequencing projects. It is anchored on individual ESTs and organized around different properties of ESTs including chromatograms, base-calling quality scores, structure of assembled transcripts, and multiple sources of comparison to infer functional annotation, Gene Ontology associations, and cDNA library information. ESTIMA consists of a relational database schema and a set of interactive query interfaces. These are integrated with a suite of web-based tools that allow a user to query and retrieve information. Further, query results are interconnected among the various EST properties. ESTIMA has several unique features. Users may run their own EST processing pipeline, search against preferred reference genomes, and use any clustering and assembly algorithm. The ESTIMA database schema is very flexible and accepts output from any EST processing and assembly pipeline. ESTIMA has been used for the management of EST projects of many species, including honeybee (Apis mellifera, cattle (Bos taurus, songbird (Taeniopygia guttata, corn rootworm (Diabrotica vergifera, catfish (Ictalurus punctatus, Ictalurus furcatus, and apple (Malus x domestica.

    Es imprescindible que la reflexión estética aborde el problema de la crisis del arte actual y que analice las distintas respuestas que en la práctica se le están dando. La renovación del diálogo con planteamientos estéticos tradicionales puede arrojar una nueva luz sobre la actividad de la creatividad artística, al destacar los conceptos de emoción y conocimiento entre otros.

    Bombax ceiba (Malvaceae), commonly known as silk cotton tree, is a multipurpose tree species of tropical forests. Novel expressed sequence tag-simple sequence repeat (EST-SSR) markers were developed and characterized for the species using transcriptome analysis. A total of 33 new EST-SSR markers were developed for B. ceiba, of which 13 showed polymorphisms across the 24 individuals from four distant populations tested in the study. The results showed that the number of alleles per polymorphic locus ranged from two to four, and the expected heterozygosity and observed heterozygosity per locus varied from 0.043 to 0.654 and from 0 to 0.609, respectively. These newly developed EST-SSR markers can be used in phylogeographic and population genetic studies to investigate the origin of B. ceiba populations. Furthermore, these EST-SSR markers could also greatly promote the development of molecular breeding studies pertaining to silk cotton tree.

  16. Environmental Factors Modulating the Stability and Enzymatic Activity of the Petrotoga mobilis Esterase (PmEst.

    Directory of Open Access Journals (Sweden)

    Jose L S Lopes

    Full Text Available Enzymes isolated from thermophilic organisms found in oil reservoirs can find applications in many fields, including the oleochemical, pharmaceutical, bioenergy, and food/dairy industries. In this study, in silico identification and recombinant production of an esterase from the extremophile bacteria Petrotoga mobilis (designated PmEst were performed. Then biochemical, bioinformatics and structural characterizations were undertaken using a combination of synchrotron radiation circular dichroism (SRCD and fluorescence spectroscopies to correlate PmEst stability and hydrolytic activity on different substrates. The enzyme presented a high Michaelis-Menten constant (KM 0.16 mM and optimum activity at ~55°C for p-nitrophenyl butyrate. The secondary structure of PmEst was preserved at acid pH, but not under alkaline conditions. PmEst was unfolded at high concentrations of urea or guanidine through apparently different mechanisms. The esterase activity of PmEst was preserved in the presence of ethanol or propanol and its melting temperature increased ~8°C in the presence of these organic solvents. PmEst is a mesophilic esterase with substrate preference towards short-to medium-length acyl chains. The SRCD data of PmEst is in agreement with the prediction of an α/β protein, which leads us to assume that it displays a typical fold of esterases from this family. The increased enzyme stability in organic solvents may enable novel applications for its use in synthetic biology. Taken together, our results demonstrate features of the PmEst enzyme that indicate it may be suitable for applications in industrial processes, particularly, when the use of polar organic solvents is required.

    Full Text Available Identification of monokaryons and their mating types and discrimination of hybrid offspring are key steps for the crossbreeding of Pleurotus tuoliensis (Bailinggu. However, conventional crossbreeding methods are troublesome and time consuming. Using RNA-seq technology, we developed new expressed sequence tag-simple sequence repeat (EST-SSR markers for Bailinggu to easily and rapidly identify monokaryons and their mating types, genetic diversity and hybrid offspring. We identified 1110 potential EST-based SSR loci from a newly-sequenced Bailinggu transcriptome and then randomly selected 100 EST-SSRs for further validation. Results showed that 39, 43 and 34 novel EST-SSR markers successfully identified monokaryons from their parent dikaryons, differentiated two different mating types and discriminated F1 and F2 hybrid offspring, respectively. Furthermore, a total of 86 alleles were detected in 37 monokaryons using 18 highly informative EST-SSRs. The observed number of alleles per locus ranged from three to seven. Cluster analysis revealed that these monokaryons have a relatively high level of genetic diversity. Transfer rates of the EST-SSRs in the monokaryons of closely-related species Pleurotus eryngii var. ferulae and Pleurotus ostreatus were 72% and 64%, respectively. Therefore, our study provides new SSR markers and an efficient method to enhance the crossbreeding of Bailinggu and closely-related species.

    Tree peony (Paeonia suffruticosa Andrews), a woody deciduous shrub, belongs to the section Moutan DC. in the genus of Paeonia of the Paeoniaceae family. To increase the efficiency of breeding, two EST-derived marker systems were developed based on a tree peony expressed sequence tag (EST) database. Using target region amplification polymorphism (TRAP), 19 of 39 primer pairs showed good amplification for 56 accessions with amplicons ranging from 120 to 3,000 bp long, among which 99.3% were polymorphic. In contrast, 7 of 21 primer pairs demonstrated adequate amplification with clear bands for simple sequence repeats (SSRs) developed from ESTs, and a total of 33 alleles were found in 56 accessions. The similarity matrices generated by TRAP and EST-SSR markers were compared, and the Mantel test (r = 0.57778, P = 0.0020) showed a moderate correlation between the two types of molecular markers. TRAP markers were suitable for DNA fingerprinting and EST-SSR markers were more appropriate for discriminating synonyms (the same cultivars with different names due to limited information exchanged among different geographic areas). The two sets of EST-derived markers will be used further for genetic linkage map construction and quantitative trait locus detection in tree peony.

    Full Text Available Este artículo plantea que si bien la mayoría de los arquitectos coincide en la urgente necesidad de integrar criterios de sustentabilidad ambiental en el proyecto, aún nos encontramos con que el tipo de arquitectura que logra tribuna en los medios está dominada por la imagen, mientras que los ejemplos de arquitectura sustentable son criticados por considerarse estéticamente pobres. Sin embargo, la arquitectura sustentable no implica necesariamente agregar una apariencia estética a un comportamiento físico que persigue objetivos de sustentabilidad, sino que crear una relación integral entre valores estéticos y fundamentos científicos. En un escenario de búsqueda de integración entre ética y estética a través de múltiples y diversos caminos hacia la sustentabilidad, no debemos dejar de mirar con suspicacia aquellas tendencias que se basan en un supuesto consenso universal acerca de lo que la arquitectura sustentable debe ser y en la creencia de que ésta puede ser evaluada objetivamente en base a la desintegración de la obra en un listado de parámetros. En arquitectura, el todo es siempre más que la suma de las partes.

    The ESTE system (Emergency Source Term Evaluation) is support instrument for off-site emergency response and its main objective is to assist to the crisis staff: - to mitigate radiological consequences of significant releases; - to manage the protective measures; - to manage emergency monitoring. At national level the ESTE system are implemented at the Emergency Response Centre of the Czech Republic (SUJB) and Austrian versions are implemented at the Crisis Centre of the Austrian Republic (BMLFUW). ESTE system can now be utilized not only in close (40 km) vicinity of the point of the release (NPP), but radiological impacts are now calculated across the whole country or over the country border. Puff Trajectory Model (PTM) with the background of geographical information system (GIS) is included in este. Numerical weather prediction data (wind fields) predicted for the whole or the part of the country are online connected with este and utilized for the puffs movement simulation and impacts calculations. It means that not only meteorological data from the point of release (measured or predicted), but 'meteorological data wind field' predicted for larger region across the country are used by the este system.

  4. Exploiting the transcriptome of Euphrates Poplar, Populus euphratica (Salicaceae to develop and characterize new EST-SSR markers and construct an EST-SSR database.

    Directory of Open Access Journals (Sweden)

    Fang K Du

    Full Text Available BACKGROUND: Microsatellite markers or Simple Sequence Repeats (SSRs are the most popular markers in population/conservation genetics. However, the development of novel microsatellite markers has been impeded by high costs, a lack of available sequence data and technical difficulties. New species-specific microsatellite markers were required to investigate the evolutionary history of the Euphratica tree, Populus euphratica, the only tree species found in the desert regions of Western China and adjacent Central Asian countries. METHODOLOGY/PRINCIPAL FINDINGS: A total of 94,090 non-redundant Expressed Sequence Tags (ESTs from P. euphratica comprising around 63 Mb of sequence data were searched for SSRs. 4,202 SSRs were found in 3,839 ESTs, with 311 ESTs containing multiple SSRs. The most common motif types were trinucleotides (37% and hexanucleotides (33% repeats. We developed primer pairs for all of the identified EST-SSRs (eSSRs and selected 673 of these pairs at random for further validation. 575 pairs (85% gave successful amplification, of which, 464 (80.7% were polymorphic in six to 24 individuals from natural populations across Northern China. We also tested the transferability of the polymorphic eSSRs to nine other Populus species. In addition, to facilitate the use of these new eSSR markers by other researchers, we mapped them onto Populus trichocarpa scaffolds in silico and compiled our data into a web-based database (http://202.205.131.253:8080/poplar/resources/static_page/index.html. CONCLUSIONS: The large set of validated eSSRs identified in this work will have many potential applications in studies on P. euphratica and other poplar species, in fields such as population genetics, comparative genomics, linkage mapping, QTL, and marker-assisted breeding. Their use will be facilitated by their incorporation into a user-friendly web-based database.

    Full Text Available O objetivo deste experimento foi verificar o efeito do treino discriminativo sobre a formação de classes funcionais de melodias em andamentos e modos diferentes. Nove estudantes universitários do 2° período da graduação em Psicologia foram divididos em três grupos: Modo, Andamento ou Misto. O software SomPsi, produzido especialmente para este estudo, treinou os participantes e gerou relatórios com informações sobre os desempenhos, nas quatro fases do procedimento. O treino proposto mostrou-se eficiente para a formação das classes funcionais de estímulos sonoros musicais. Observou-se que agrupamentos de estímulos pela propriedade andamento foram mais facilmente discriminados que os agrupados pela melodia. A manipulação combinada das duas propriedades, em condição convergente, permitiu desempenho superior dos participantes. A rápida formação de classes funcionais e equivalentes de estímulos musicais, a partir de procedimentos de ensino automatizado de relações condicionais entre estímulos musicais, indica a possibilidade de uso desse procedimento na iniciação à música.

    Full Text Available La Estética no se ocupa únicamente del arte o de la belleza, aunque habitualmente así se crea. Por el contrario, ella es el ámbito de todo lo sensible, es decir, del conocimiento sensorial y de las emociones producidas por las sensaciones. El artículo resalta la importancia de la sensibilidad en la actuación de los trabajadores sociales. Toma en cuenta tanto las sensaciones que recibimos nosotros como las que producimos en los demás. Desde esta perspectiva se abordan temas como la capacidad de observación, la inteligencia emocional, los estilos de vida, los estilos de trabajo, la resonancia, la sintonía con el cliente o el síndrome del profesional «quemado». Más aún, este ámbito de las sensaciones no está lejos del mundo teórico sino que es su punto de partida y su piedra de toque. En realidad, el mundo abstracto no existe sin el sensible. Y uno y otro tienen una dimensión relacional y ética. De este modo, el artículo termina criticando la separación de la ciencia, la estética y la ética como «esferas» de la cultura.

    Obtaining unique oligos from an EST database is a problem of great importance in bioinformatics, particularly in the discovery of new genes and the mapping of the human genome. Many algorithms have been developed to find unique oligos, many of which are much less time consuming than the traditional brute force approach. An algorithm was presented by Zheng et al. (2004) which finds the solution of the unique oligos search problem efficiently. We implement this algorithm as well as several new algorithms based on some theorems included in this paper. We demonstrate how, with these new algorithms, we can obtain unique oligos much faster than with previous ones. We parallelize these new algorithms to further improve the time of finding unique oligos. All algorithms are run on ESTs obtained from a Barley EST database.

Além de relatar a experiência, foi realizado um levantamento junto aos ex-alunos sobre as contribuições do estágio na sua formação educacional e profissional. Da experiência relatada foi possível verificar que: a instituição das Diretrizes Curriculares Nacionais (DCN constituiu-se em um marco na flexibilização curricular dos cursos; o estágio é um componente curricular de integração entre ensino, pesquisa e prática; e o estágio em POT requer dos discentes conhecimentos multidisciplinares. Além desses aspectos, observou-se que a prática do estágio supervisionado indica o rompimento com a imagem negativa do psicólogo que atua em POT, limitada à aplicação de testes e psicotécnicas. De fato, a atividade do psicólogo em POT mostrou-se muito mais ampla e complexa, sobretudo em termos dos impactos de sua intervenção no ambiente organizacional.

    Surveying Fusarium resistance in wheat with easy applicable molecular markers such as simple sequence repeats (SSRs) is a prerequest for molecular breeding. Expressed sequence tags (ESTs) are one of the main sources for development of new SSR candidates. Therefore, 18.292 publicly available wheat ESTs were mined and genotyping of newly developed 55 EST-SSR derived primer pairs produced clear fragments in ten wheat cultivars carrying different levels of Fusarium resistance. Among the proved markers, 23 polymorphic EST-SSRs were obtained and related alleles were mostly found on B and D genome. Based on the fragment profiling and similarity analysis, a 327bp amplicon, which was a product of contig 1207 (chromosome 5BL), was detected only in Fusarium head blight (FHB) resistant cultivars (CM82036 and Sumai) and the amino acid sequences showed a similarity to pathogen related proteins. Another FHB resistance related EST-SSR, Contig 556 (chromosome 1BL) produced a 151bp fragment in Sumai and was associated to wax2-like protein. A polymorphic 204bp fragment, derived from Contig 578 (chromosome 1DL), was generated from root rot (FRR) resistant cultivars (2-49; Altay2000 and Sunco). A total of 98 alleles were displayed with an average of 1.8 alleles per locus and the polymorphic information content (PIC) ranged from 0.11 to 0.78. Dendrogram tree with two main and five sub-groups were displayed the highest genetic relationship between FRR resistant cultivars (2-49 and Altay2000), FRR sensitive cultivars (Seri82 and Scout66) and FHB resistant cultivars (CM82036 and Sumai). Thus, exploitation of these candidate EST-SSRs may help to genotype other wheat sources for Fusarium resistance. Copyright © 2017 Elsevier Ltd. All rights reserved.

    In the present study, genetic variation among 40 cucumber genotypes was analyzed by means of morpho-physiological traits and 21 EST-SSR markers. Diversity was observed for morpho-physiological characters like days to 50% female flowering (37-46.9, number of fruits/plant (1.33-5.80), average fruit weight (41-333), vine length (36-364), relative water content (58.5-92.7), electrolyte leakage (15.9-37.1), photosynthetic efficiency (0.40-0.75) and chlorophyll concentration index (11.1-28.6). The pair wise Jaccard similarity coefficient ranged from 0.00 to 0.27 for quantitative traits and 0.24 to 0.96 for EST-SSR markers indicating that the accessions represent genetically diverse populations. With twenty-one EST-SSR markers, polymorphism revealed among 40 cucumber genotypes, number of alleles varied 2-6 with an average 3.05. Polymorphism information content varied from 0.002 to 0.989 (mean = 0.308). The number of effective allele (Ne), expected heterozygosity (He) and unbiased expected heterozygosity (uHe) of these EST-SSRs were 1.079-1.753, 0.074-0.428 and 0.074-0.434, respectively. Same 21 EST-SSR markers transferability checked in four other Cucumis species: snapmelon ( Cucumis melo var. momordica ), muskmelon ( Cucumis melo L.), pickling melon ( Cucumis melo var. conomon ) and wild muskmelon ( Cucumis melo var. agrestis ) with frequency of 61.9, 95.2, 76.2, and 76.2%, respectively. Present study provides useful information on variability, which can assist geneticists with desirable traits for cucumber germplasm utilization. Observed physiological parameters may assists in selection of genotype for abiotic stress tolerance also, EST-SSR markers may be useful for genetic studies in related species.

  10. EST analysis in Ginkgo biloba: an assessment of conserved developmental regulators and gymnosperm specific genes

    Runko Suzan J

    2005-10-01

    Full Text Available Abstract Background Ginkgo biloba L. is the only surviving member of one of the oldest living seed plant groups with medicinal, spiritual and horticultural importance worldwide. As an evolutionary relic, it displays many characters found in the early, extinct seed plants and extant cycads. To establish a molecular base to understand the evolution of seeds and pollen, we created a cDNA library and EST dataset from the reproductive structures of male (microsporangiate, female (megasporangiate, and vegetative organs (leaves of Ginkgo biloba. Results RNA from newly emerged male and female reproductive organs and immature leaves was used to create three distinct cDNA libraries from which 6,434 ESTs were generated. These 6,434 ESTs from Ginkgo biloba were clustered into 3,830 unigenes. A comparison of our Ginkgo unigene set against the fully annotated genomes of rice and Arabidopsis, and all available ESTs in Genbank revealed that 256 Ginkgo unigenes match only genes among the gymnosperms and non-seed plants – many with multiple matches to genes in non-angiosperm plants. Conversely, another group of unigenes in Gingko had highly significant homology to transcription factors in angiosperms involved in development, including MADS box genes as well as post-transcriptional regulators. Several of the conserved developmental genes found in Ginkgo had top BLAST homology to cycad genes. We also note here the presence of ESTs in G. biloba similar to genes that to date have only been found in gymnosperms and an additional 22 Ginkgo genes common only to genes from cycads. Conclusion Our analysis of an EST dataset from G. biloba revealed genes potentially unique to gymnosperms. Many of these genes showed homology to fully sequenced clones from our cycad EST dataset found in common only with gymnosperms. Other Ginkgo ESTs are similar to developmental regulators in higher plants. This work sets the stage for future studies on Ginkgo to better understand seed and

    Profiling studies of mRNA and miRNA, particularly microarray-based studies, have been extensively used to create compendia of genes that are preferentially expressed in the immune system. In some instances, functional studies have been subsequently pursued. Recent efforts such as ENCODE have demonstrated the benefit of coupling RNA-Seq analysis with information from expressed sequence tags (ESTs) for transcriptomic analysis. However, the full characterization and identification of transcripts that function as modulators of human immune responses remains incomplete. In this study, we demonstrate that an integrated analysis of human ESTs provides a robust platform to identify the immune transcriptome. Beyond recovering a reference set of immune-enriched genes and providing large-scale cross-validation of previous microarray studies, we discovered hundreds of novel genes preferentially expressed in the immune system, including non-coding RNAs. As a result, we have established the Immunogene database, representing an integrated EST “road map” of gene expression in human immune cells, which can be used to further investigate the function of coding and non-coding genes in the immune system. Using this approach, we have uncovered a unique metabolic gene signature of human macrophages and identified PRDM15 as a novel overexpressed gene in human lymphomas. Thus we demonstrate the utility of EST profiling as a basis for further deconstruction of physiologic and pathologic immune processes. PMID:23616578

    The production of heavy crude oils is projected to continue to grow in the upstream oil industry given that large reserves of unconventional extra heavy crude and bitumen exist in several geographic areas including Canada and Venezuela. As reserves of conventional crude oil continue to decline, these unconventional feedstocks are becoming an opportunity to pursue, but they require effective technologies for upgrading and meeting the growing demand for light and middle distillate fuels. This paper described the proprietary technology that offers a solution to upstream and downstream oil producers for bottom-of-the-barrel upgrading. En i Slurry Technology (EST) is constructing an industrial plant in its Sannazzaro refinery in Italy. The plant is designed to convert 23,000 BPSD of vacuum residue into high quality diesel and other valuable refinery streams such as liquefied petroleum gas, naphtha and jet fuel. EST is an H-addition process characterized by the use of a special homogeneous isothermal intrinsically safe reactor, and of a nano-dispersed non-ageing catalyst. EST converts more than 98 per cent of any type of residues to about 110 per cent volume of light products and distillates or extra heavy oils to high quality bottomless SCO. In typical performance, HDS is greater than 85 per cent, HDM greater than 99 per cent and HDCCR greater than 97 per cent. EST also achieves the target of zero fuel oil - zero coke. 12 refs., 4 tabs., 5 figs.

O grau de dificuldade da tarefa dependia da diferença de orientação das mesmas. Simultaneamente era apresentada uma figura central (neutra ou negativa entre as barras. Foi observado que as figuras negativas interferiram no desempenho dos voluntários mesmo na tarefa mais difícil, que exigia maior engajamento atencional. Além disto, quando o reconhecimento posterior destas figuras era testado, figuras negativas eram mais lembradas do que neutras. Estes dados sugerem que estímulos emocionais são privilegiados na disputa por recursos de atenção. É possível que esse privilégio ocorra devido a relevância destes estímulos, sendo dificilmente ignorados.

    Ligusticum chuanxiong is a well-known traditional Chinese medicine plant. The study on its molecular markers development and germplasm resources is very important. In this study, we obtained 24 422 unigenes by assembling transcriptome sequencing reads of L. chuanxiong root. EST-SSR was detected and 4 073 SSR loci were identified. EST-SSR distribution and characteristic analysis results showed that the mono-nucleotide repeats were the main repeat types, accounting for 41.0%. In addition, the sequences containing SSR were functionally annotated in Gene Ontology (GO) and KEGG pathway and were assigned to 49 GO categories, 242 KEGG pathways, among them 2 201 sequences were annotated against Nr database. By validating 235 EST-SSRs,74 primer pairs were ultimately proved to have high quality amplification. Subsequently, genetic diversity analysis, UPGMA cluster analysis, PCoA analysis and population structure analysis of 34 L. chuanxiong germplasm resources were carried out with 74 primer pairs. In both UPGMA tree and PCoA results, L. chuanxiong resources were clustered into two groups, which are believed to be partial related to their geographical distribution. In this study, EST-SSRs in L. chuanxiong was firstly identified, and newly developed molecular markers would contribute significantly to further genetic diversity study, the purity detection, gene mapping, and molecular breeding.

    Full Text Available Premise of the study: New microsatellite (simple sequence repeat [SSR] primers were developed from Eucalyptus expressed sequence tags (ESTs and optimized for genetic studies of the southwestern Australian tree E. gomphocephala, which is severely impacted by tree health decline and habitat fragmentation. Methods and Results: A total of 133 gene-homologous EST-SSR primer pairs were designed for Eucalyptus, and 44 were screened in E. gomphocephala. Of these, 17 produced reliable amplification products and 11 were polymorphic. Between two and 13 alleles were observed per locus, and observed heterozygosities ranged from 0.172 to 0.867. All 17 EST-SSRs that amplified E. gomphocephala cross-amplified to at least one of E. marginata, E. camaldulensis, and E. victrix. Conclusions: This set of EST-SSR primer pairs will be valuable tools for future population genetic studies of E. gomphocephala and other eucalypts, particularly for studying gene-linked variation and informing seed-sourcing strategies for ecological restoration.

    Full Text Available Cuando se alude a las Estéticas características del Nazismo, solemos empezar por pensar en grandes desfiles, encuentros de la juventud, marchas de antorchas, masivos sermones al aire libre y multitudes enardecidas dispuestas a lanzarse a degüello sobre el enemigo más próximo. Sin embargo no es eso lo que se desprende en absoluto, ni de un análisis de los materiales y prácticas, ni del estudio de los textos y declaraciones de los principales responsables de la producción estética del nazismo. Veremos en este artículo, por el contrario, que la apuesta de la inmensa mayoría de la producción estética nazi estuvo vinculada a la producción y estabilización de ciudadanos tan normales y razonables como nos sea dado concebir hoy mismo.

    Full Text Available Considerando a importância da paca (Cuniculus paca, Linnaeus, 1766, tanto como fonte proteica alternativa para a população quanto pela possibilidade de vir a se tornar um animal de experimentação e pela falta de informações sobre a sua anatomia, objetivou-se descrever a morfologia macroscópica e histológica do estômago e do duodeno desse roedor, reconhecendo as relações, forma e posição que esses órgãos estabelecem entre si e com outros órgãos. O estômago da paca é unicavitário, está no plano médio mais voltado para o antímero esquerdo, transversalmente, na região hipocôndrica em posição ventrocaudal, interposto entre o esôfago e o duodeno. O duodeno da paca se inicia em sequência ao estômago, segue caudalmente até o nível da quinta ou sexta vértebra lombar, na altura das quais se curva e toma direção cranial, dirigindo-se até o nível da transição entre a última vértebra torácica e a primeira vértebra lombar, onde se continua como jejuno. Histologicamente, o estômago e o duodeno da paca possuem o padrão característico da arquitetura dos órgãos ocos, apresentando as seguintes túnicas: mucosa, submucosa, muscular e serosa. Da forma que se conduziu este estudo, conclui-se que o estômago e duodeno da paca, de forma geral, possuem características morfológicas macroscópicas e histológicas semelhantes às dos animais domésticos e de outros roedores selvagens.

    Full Text Available Abstract Background Currently there exists a limited availability of genetic marker resources in sweetpotato (Ipomoea batatas, which is hindering genetic research in this species. It is necessary to develop more molecular markers for potential use in sweetpotato genetic research. With the newly developed next generation sequencing technology, large amount of transcribed sequences of sweetpotato have been generated and are available for identifying SSR markers by data mining. Results In this study, we investigated 181,615 ESTs for the identification and development of SSR markers. In total, 8,294 SSRs were identified from 7,163 SSR-containing unique ESTs. On an average, one SSR was found per 7.1 kb of EST sequence with tri-nucleotide motifs (42.9% being the most abundant followed by di- (41.2%, tetra- (9.2%, penta- (3.7% and hexa-nucleotide (3.1% repeat types. The top five motifs included AG/CT (26.9%, AAG/CTT (13.5%, AT/TA (10.6%, CCG/CGG (5.8% and AAT/ATT (4.5%. After removing possible duplicate of published EST-SSRs of sweetpotato, a total of non-repeat 7,958 SSR motifs were identified. Based on these SSR-containing sequences, 1,060 pairs of high-quality SSR primers were designed and used for validation of the amplification and assessment of the polymorphism between two parents of one mapping population (E Shu 3 Hao and Guang 2k-30 and eight accessions of cultivated sweetpotatoes. The results showed that 816 primer pairs could yield reproducible and strong amplification products, of which 195 (23.9% and 342 (41.9% primer pairs exhibited polymorphism between E Shu 3 Hao and Guang 2k-30 and among the 8 cultivated sweetpotatoes, respectively. Conclusion This study gives an insight into the frequency, type and distribution of sweetpotato EST-SSRs and demonstrates successful development of EST-SSR markers in cultivated sweetpotato. These EST-SSR markers could enrich the current resource of molecular markers for the sweetpotato community and would

    2005-08-01

    Full Text Available Abstract Background Chickpea is a major crop in many drier regions of the world where it is an important protein-rich food and an increasingly valuable traded commodity. The wild annual Cicer species are known to possess unique sources of resistance to pests and diseases, and tolerance to environmental stresses. However, there has been limited utilization of these wild species by chickpea breeding programs due to interspecific crossing barriers and deleterious linkage drag. Molecular genetic diversity analysis may help predict which accessions are most likely to produce fertile progeny when crossed with chickpea cultivars. While, trait-markers may provide an effective tool for breaking linkage drag. Although SSR markers are the assay of choice for marker-assisted selection of specific traits in conventional breeding populations, they may not provide reliable estimates of interspecific diversity, and may lose selective power in backcross programs based on interspecific introgressions. Thus, we have pursued the development of gene-based markers to resolve these problems and to provide candidate gene markers for QTL mapping of important agronomic traits. Results An EST library was constructed after subtractive suppressive hybridization (SSH of root tissue from two very closely related chickpea genotypes (Cicer arietinum. A total of 106 EST-based markers were designed from 477 sequences with functional annotations and these were tested on C. arietinum. Forty-four EST markers were polymorphic when screened across nine Cicer species (including the cultigen. Parsimony and PCoA analysis of the resultant EST-marker dataset indicated that most accessions cluster in accordance with the previously defined classification of primary (C. arietinum, C. echinospermum and C. reticulatum, secondary (C. pinnatifidum, C. bijugum and C. judaicum, and tertiary (C. yamashitae, C. chrossanicum and C. cuneatum gene-pools.

    EVER-EST is an EC Horizon 2020 project having the goal to develop a Virtual Research Environment (VRE) providing a state-of-the-art solution to allow Earth Scientists to preserve their work and publications for reference and future reuse, and to share with others. The availability of such a solution, based on an innovative concept and state of art technology infrastructure, will considerably enhance the quality of how Earth Scientists work together within their own institution and also across other organizations, regions and countries. The concept of Research Objects (ROs), used in the Earth Sciences for the first time, will form the backbone of the EVER-EST VRE infrastructure. ROs will enhance the ability to preserve, re-use and share entire or individual parts of scientific workflows and all the resources related to a specific scientific investigation. These ROs will also potentially be used as part of the scholarly publication process. EVER-EST is building on technologies developed during almost 15 years of research on Earth Science data management infrastructures. The EVER-EST VRE Service Oriented Architecture is being meticulously designed to accommodate at best the requirements of a wide range of Earth Science communities and use cases: focus is put on common requirements and on minimising the level of complexity in the EVER-EST VRE to ensure future sustainability within the user communities beyond the end of the project. The EVER-EST VRE will be validated through its customisation and deployment by four Virtual Research Communities (VRCs) from different Earth Science disciplines and will support enhanced interaction between data providers and scientists in the Earth Science domain. User community will range from bio-marine researchers (Sea Monitoring use case), to common foreign and security policy institutions and stakeholders (Land Monitoring for Security use case), natural hazards forecasting systems (Natural Hazards use case), and disaster and risk

  3. Strengths and weaknesses of EST-based prediction of tissue-specific alternative splicing

    Directory of Open Access Journals (Sweden)

    Vingron Martin

    2004-09-01

    Full Text Available Abstract Background Alternative splicing contributes significantly to the complexity of the human transcriptome and proteome. Computational prediction of alternative splice isoforms are usually based on EST sequences that also allow to approximate the expression pattern of the related transcripts. However, the limited number of tissues represented in the EST data as well as the different cDNA construction protocols may influence the predictive capacity of ESTs to unravel tissue-specifically expressed transcripts. Methods We predict tissue and tumor specific splice isoforms based on the genomic mapping (SpliceNest of the EST consensus sequences and library annotation provided in the GeneNest database. We further ascertain the potentially rare tissue specific transcripts as the ones represented only by ESTs derived from normalized libraries. A subset of the predicted tissue and tumor specific isoforms are then validated via RT-PCR experiments over a spectrum of 40 tissue types. Results Our strategy revealed 427 genes with at least one tissue specific transcript as well as 1120 genes showing tumor specific isoforms. While our experimental evaluation of computationally predicted tissue-specific isoforms revealed a high success rate in confirming the expression of these isoforms in the respective tissue, the strategy frequently failed to detect the expected restricted expression pattern. The analysis of putative lowly expressed transcripts using normalized cDNA libraries suggests that our ability to detect tissue-specific isoforms strongly depends on the expression level of the respective transcript as well as on the sensitivity of the experimental methods. Especially splice isoforms predicted to be disease-specific tend to represent transcripts that are expressed in a set of healthy tissues rather than novel isoforms. Conclusions We propose to combine the computational prediction of alternative splice isoforms with experimental validation for

    Full Text Available Abstract Background Ice, snow and temperatures of -14°C are conditions which most animals would find difficult, if not impossible, to survive in. However this exactly describes the Arctic winter, and the Arctic springtail Onychiurus arcticus regularly survives these extreme conditions and re-emerges in the spring. It is able to do this by reducing the amount of water in its body to almost zero: a process that is called "protective dehydration". The aim of this project was to generate clones and sequence data in the form of ESTs to provide a platform for the future molecular characterisation of the processes involved in protective dehydration. Results Five normalised libraries were produced from both desiccating and rehydrating populations of O. arcticus from stages that had previously been defined as potentially informative for molecular analyses. A total of 16,379 EST clones were generated and analysed using Blast and GO annotation. 40% of the clones produced significant matches against the Swissprot and trembl databases and these were further analysed using GO annotation. Extraction and analysis of GO annotations proved an extremely effective method for identifying generic processes associated with biochemical pathways, proving more efficient than solely analysing Blast data output. A number of genes were identified, which have previously been shown to be involved in water transport and desiccation such as members of the aquaporin family. Identification of these clones in specific libraries associated with desiccation validates the computational analysis by library rather than producing a global overview of all libraries combined. Conclusion This paper describes for the first time EST data from the arctic springtail (O. arcticus. This significantly enhances the number of Collembolan ESTs in the public databases, providing useful comparative data within this phylum. The use of GO annotation for analysis has facilitated the identification of a

A história da joalheria e a da estética são relacionadas, ressaltando as mudanças sociológicas das principais rupturas escolásticas nas artes e na filosofia das formas. A atividade do designer de joias está atrelada aos estudos do mercado, da trajetória do belo, na sociedade, com o objetivo de encarnar na forma e sua essência no objeto estético. O conhecimento em profundidade sobre o belo e suas categorias estéticas seguem o seu tempo e mercado, permitindo ao designer liberar o caminho para o juízo crítico, a faculdade de pensar a forma, na fronteira entre teoria e prática, emoção e cálculo. A joia contemporânea reluz o belo, a técnica, a ideia, o imaginário. A estética contemporânea pondera a escassez de matéria-prima e os vários pensamentos que refletem na criação da forma. O conteúdo deste texto pincela brevemente a importância do conhecimento do designer no desenvolvimento de novas formas para atender às exigências do mercado.

    Full Text Available Abstract Background Flesh flies in the genus Sarcophaga are important models for investigating endocrinology, diapause, cold hardiness, reproduction, and immunity. Despite the prominence of Sarcophaga flesh flies as models for insect physiology and biochemistry, and in forensic studies, little genomic or transcriptomic data are available for members of this genus. We used massively parallel pyrosequencing on the Roche 454-FLX platform to produce a substantial EST dataset for the flesh fly Sarcophaga crassipalpis. To maximize sequence diversity, we pooled RNA extracted from whole bodies of all life stages and normalized the cDNA pool after reverse transcription. Results We obtained 207,110 ESTs with an average read length of 241 bp. These reads assembled into 20,995 contigs and 31,056 singletons. Using BLAST searches of the NR and NT databases we were able to identify 11,757 unique gene elements (ES. crassipalpis unigenes among GO Biological Process functional groups with that of the Drosophila melanogaster transcriptome suggests that our ESTs are broadly representative of the flesh fly transcriptome. Insertion and deletion errors in 454 sequencing present a serious hurdle to comparative transcriptome analysis. Aided by a new approach to correcting for these errors, we performed a comparative analysis of genetic divergence across GO categories among S. crassipalpis, D. melanogaster, and Anopheles gambiae. The results suggest that non-synonymous substitutions occur at similar rates across categories, although genes related to response to stimuli may evolve slightly faster. In addition, we identified over 500 potential microsatellite loci and more than 12,000 SNPs among our ESTs. Conclusion Our data provides the first large-scale EST-project for flesh flies, a much-needed resource for exploring this model species. In addition, we identified a large number of potential microsatellite and SNP markers that could be used in population and systematic

    Full Text Available La experiencia estética se constituye en un elemento crucial para la obra de John Dewey. En primer lugar, este pensador recupera la idea de experiencia, en sentido amplio, referida a los procesos conscientes realizados por el ser humano. En segundo lugar, esta experiencia aparece como resultado de la interacción de los hombres con su entorno, de tal modo que se amplían las valoraciones que aquellos tienen acerca de éste. En tercer lugar, la experiencia tiene elementos analíticos y sintéticos que posibilitan cualificar los procesos cognitivos y cognoscitivos de los individuos. En cuarto lugar, la experiencia se clasifica de acuerdo a su función en intelectual, práctica y estética, siendo la última la más importante, en tanto que, se muestra como más universal y ampliada frente a las otras, y se comporta como experiencia educativa al ser la que cualifica de manera más profunda los juicios críticos que se hacen frente al mundo.Los anteriores aspectos serán trabajados en este artículo, con miras a explorar la universalidad de la experiencia estética deweyana y sus derivaciones en el campo de una propuesta educativa, en la que resulta de vital importancia la existencia de una experiencia común entre los diferentes grupos humanos para lograr configurar la inteligencia común que es la base para la educación en John Dewey.

    Full Text Available Development of Expressed Sequence Tag-Simple Sequence Repeat (EST-SSR markers derived from public database is known to be more efficient, faster and low cost. The objective of this study was to generate a new set of EST-SSR markers for broccoli and its related species and their usefulness for assessing their genetic diversity. A total of 202 Brassica oleracea ESTs were retrieved from NCBI and then assembled into 172 unigenes by means of CAP3 program. Identification of SSRs was carried out using web-based tool, RepeatMasker software. Afterwards, EST-SSR markers were developed using Primer3 program. Among the identified SSRs, trinucleotide repeats were the most common repeat types, which accounted for about 50%. A total of eight primer pairs were successfully designed and yielded amplification products. Among them, five markers were polymorphic and displayed a total of 30 alleles with an average number of six alleles per locus. The polymorphic markers were subsequently used for analyzing genetic diversity of 36 B. oleracea cultivars including 22 broccoli, five cauliflower and nine kohlrabi cultivars based on genetic similarity matrix as implemented in NTSYS program. At similarity coefficient of 61%, a UPGMA clustering dendrogram effectively separated 36 genotypes into three main groups, where 30 out of 36 genotypes were clearly discriminated. The result obtained in the present study would help breeders in selecting parental lines for crossing. Moreover, the novel EST-SSR markers developed in the study could be a valuable tool for differentiating cultivars of broccoli and related species.

    Cartilaginous fishes are the most ancient group of living jawed vertebrates (gnathostomes) and are, therefore, an important reference group for understanding the evolution of vertebrates. The elephant shark (Callorhinchus milii), a holocephalan cartilaginous fish, has been identified as a model cartilaginous fish genome because of its compact genome (∼910 Mb) and a genome project has been initiated to obtain its whole genome sequence. In this study, we have generated and sequenced full-length enriched cDNA libraries of the elephant shark using the 'oligo-capping' method and Sanger sequencing. A total of 6,778 full-length protein-coding cDNA and 10,701 full-length noncoding cDNA were sequenced from six tissues (gills, intestine, kidney, liver, spleen, and testis) of the elephant shark. Analysis of their polyadenylation signals showed that polyadenylation usage in elephant shark is similar to that in mammals. Furthermore, both coding and noncoding transcripts of the elephant shark use the same proportion of canonical polyadenylation sites. Besides BLASTX searches, protein-coding transcripts were annotated by Gene Ontology, InterPro domain, and KEGG pathway analyses. By comparing elephant shark genes to bony vertebrate genes, we identified several ancient genes present in elephant shark but differentially lost in tetrapods or teleosts. Only ∼6% of elephant shark noncoding cDNA showed similarity to known noncoding RNAs (ncRNAs). The rest are either highly divergent ncRNAs or novel ncRNAs. In addition to full-length transcripts, 30,375 5'-ESTs and 41,317 3'-ESTs were sequenced and annotated. The clones and transcripts generated in this study are valuable resources for annotating transcription start sites, exon-intron boundaries, and UTRs of genes in the elephant shark genome, and for the functional characterization of protein sequences. These resources will also be useful for annotating genes in other cartilaginous fishes whose genomes have been targeted for whole

    Full Text Available L’une des caractéristiques les plus communément reconnues à la discipline de la terminologie est sa conceptualité. Au contraire de l’opinion émise sur la métaphore, la terminologie s’efforce de travailler à partir de notions précises dont le sens doit être délimité et l’articulation à d’autres notions explicitée afin de bannir les ambiguïtés et les fausses évidences qu’elles véhiculent. Elle se distingue aussi du texte poétique caractérisé en particulier par la richesse des images et le jeu sur les signifiants. On comprend dès lors pourquoi la métaphore apparaît de prime abord comme une ennemie du champ de la terminologie qu’il faudrait bannir à tout prix. Cette figure de rhétorique consistant en un transport de sens risque à tout moment de rendre inopérant l’effort d’univocité et de rigueur du travail du terminologue. Mais la métaphore n’est pourtant pas absente des textes de spécialité. Il faut dès lors se demander si cette présence est « accidentelle”, contingente, ou si elle est incontournable et signifiante. Pour cela, il nous faudra étudier à la fois la place de la métaphore dans le texte de spécialité, et le discours des scientifiques portant sur elle. Mais une telle démarche nous laisse prisonnier de la dichotomie entre concept et métaphore et masque peutêtre une parenté inaperçue entre eux. Si le concept est habité par la métaphore, qu’en est-il du discours de spécialité? N’est-il pas réduit à n’être qu’un vaste poème qui ne s’avouerait pas comme tel? Est-elle seulement une figure de style ou aurait-elle un impact qui outrepasseraitsa modeste fonction discursive ? Il semble bien, même si le débat sur la métaphore et son usage est loin d’être clos.

    Full Text Available Abstract Background The expressed sequence tag (EST methodology is an attractive option for the generation of sequence data for species for which no completely sequenced genome is available. The annotation and comparative analysis of such datasets poses a formidable challenge for research groups that do not have the bioinformatics infrastructure of major genome sequencing centres. Therefore, there is a need for user-friendly tools to facilitate the annotation of non-model species EST datasets with well-defined ontologies that enable meaningful cross-species comparisons. To address this, we have developed annot8r, a platform for the rapid annotation of EST datasets with GO-terms, EC-numbers and KEGG-pathways. Results annot8r automatically downloads all files relevant for the annotation process and generates a reference database that stores UniProt entries, their associated Gene Ontology (GO, Enzyme Commission (EC and Kyoto Encyclopaedia of Genes and Genomes (KEGG annotation and additional relevant data. For each of GO, EC and KEGG, annot8r extracts a specific sequence subset from the UniProt dataset based on the information stored in the reference database. These three subsets are then formatted for BLAST searches. The user provides the protein or nucleotide sequences to be annotated and annot8r runs BLAST searches against these three subsets. The BLAST results are parsed and the corresponding annotations retrieved from the reference database. The annotations are saved both as flat files and also in a relational postgreSQL results database to facilitate more advanced searches within the results. annot8r is integrated with the PartiGene suite of EST analysis tools. Conclusion annot8r is a tool that assigns GO, EC and KEGG annotations for data sets resulting from EST sequencing projects both rapidly and efficiently. The benefits of an underlying relational database, flexibility and the ease of use of the program make it ideally suited for non

  15. El maestro: un artesano del lenguaje. Escritura y experiencia estética de la palabra

    2015-06-01

    Full Text Available La identidad de una obra expresada a través de la escritura se teje en las voces y esfuerzos que se encarnan en memoria y dejan huella en el relato. El maestro es acción de este lenguaje movido por el historial social y cultural que permite hacer de la escritura un oficio ético y estético donde la mano construye y nombra las emociones que atraviesan al cuerpo. La escritura es el testimonio vital del maestro como artesano; es el arte del lenguaje que sale de su silencio con la lectura del relato, pero es, además, la potencia del pensamiento puesto en pretexto estético donde se pregunta y se reflexiona por el tiempo y por el espacio de la palabra, es decir, las cronologías, kairologías, territorialidades y escenarios de las esferas educativas. Sobre estos presupuestos se propone una discusión pedagógica en torno a la necesidad de pensar la escritura artesanal como intención estética y política donde se plasma el testimonio del compromiso ético del maestro, pero también la perspectiva de los nuevos retos que la educación debe asumir para reencontrar el lenguaje con la vida y con las herencias socioculturales que dan cuenta del sujeto y de las subjetividades que confluyen en los procesos de formación, y que tienen despliegue y búsqueda en el escenario creativo y productivo de la escritura. Se intentará, entonces, reivindicar una pedagogía de la posibilidad en el lenguaje, una narratividad donde la memoria traza un puente para el encuentro de épocas, de rostros, de acontecimientos, de silencios y de saberes, donde el maestro está llamado a tejer, tallar, dibujar, componer y comunicar las artesanías que la educación ha olvidado, es decir, recuperar la memoria estética, lo cual también implica un olvido de las formas hegemónicas del arte.

  16. Desartificação da arte e construtos estético-sociais

    2012-09-01

    Full Text Available Este artigo pretende examinar a relação entre a concepção de desartificação (Entkunstung, de Theodor Adorno, e a minha própria noção de “construto estético-social”. A primeira se refere à situação da arte numa época dominada pela indústria cultural e suas mercadorias, na qual, sob certas circunstâncias, os próprios artistas reduzem sua expressão a uma estrutura mínima a fim de prevenir as ameaças à sua arte por parte do “mundo administrado” (Adorno. Já o conceito de “construto estético-social é uma tentativa de compreender alguns fenômenos estéticos contemporâneos que apresentam, por um lado, traços de mercadorias culturais, já que renunciam à complexidade formal das obras de arte propriamente ditas e são – pelo menos parcialmente – veiculados por típicos meios de massa; por outro lado, eles não se enquadram totalmente na categoria de mercadoria cultural, uma vez que apresentam aspectos críticos à sociedade tardo-capitalista e são ligados a ações políticas originadas em comunidades muito pobres, que se entendem a si mesmas como dispostas a transformar aquela sociedade. Fenômenos que se enquadram na descrição de “construtos estético-sociais” podem ser encontrados, por exemplo, na cultura hip hop. A conclusão preliminar a que se chega é que, apesar de a arte desertificada e os “construtos estético-sociais” não serem exatamente a mesma coisa, há uma ligação subterrânea entre essas duas concepções, uma vez que ambas operam – de modo mais ou menos intencional – uma redução na forma de sua expressão a fim de fazer frente às exigências de uma cultura contemporânea autêntica.

  17. Tentative mapping of transcription-induced interchromosomal interaction using chimeric EST and mRNA data.

    Directory of Open Access Journals (Sweden)

    Per Unneberg

    Full Text Available Recent studies on chromosome conformation show that chromosomes colocalize in the nucleus, bringing together active genes in transcription factories. This spatial proximity of actively transcribing genes could provide a means for RNA interaction at the transcript level. We have screened public databases for chimeric EST and mRNA sequences with the intent of mapping transcription-induced interchromosomal interactions. We suggest that chimeric transcripts may be the result of close encounters of active genes, either as functional products or "noise" in the transcription process, and that they could be used as probes for chromosome interactions. We have found a total of 5,614 chimeric ESTs and 587 chimeric mRNAs that meet our selection criteria. Due to their higher quality, the mRNA findings are of particular interest and we hope that they may serve as food for thought for specialists in diverse areas of molecular biology.

  19. ESTminer: a Web interface for mining EST contig and cluster databases.

    Science.gov (United States)

    Huang, Yecheng; Pumphrey, Janie; Gingle, Alan R

    2005-03-01

    ESTminer is a Web application and database schema for interactive mining of expressed sequence tag (EST) contig and cluster datasets. The Web interface contains a query frame that allows the selection of contigs/clusters with specific cDNA library makeup or a threshold number of members. The results are displayed as color-coded tree nodes, where the color indicates the fractional size of each cDNA library component. The nodes are expandable, revealing library statistics as well as EST or contig members, with links to sequence data, GenBank records or user configurable links. Also, the interface allows 'queries within queries' where the result set of a query is further filtered by the subsequent query. ESTminer is implemented in Java/JSP and the package, including MySQL and Oracle schema creation scripts, is available from http://cggc.agtec.uga.edu/Data/download.asp agingle@uga.edu.

    Full Text Available O cinema canaliza em seu aporte uma impressão de realidade baseada na experiência empírica do realizador e da sociedade ao qual ele pertence. Em sua condição de discurso, o cinema, assim como todas as formas narrativas, abrange um enunciado e um espectador. Diferentemente de um romance, a “gramática” cinematográfica é composta por um conjunto de elementos como a imagem, som, música entre outros que, organizados, contam uma história. Entretanto, a forma como estes componentes são gravados em imagens e ordenados numa seqüência narrativa não é única. Desta forma, podemos pensar qual é o propósito de uma escolha estética usual nos filmes Pra frente Brasil e Batismo de Sangue para representar a Ditadura Militar Brasileira.

    Cynodon species are multiple-use grasses that display varying levels of adaptation to biotic and abiotic stress. Previously identified EST-SSR primers were characterized and multiplexed to assess the level of genetic diversity present within a collection of almost 1200 Cynodon accessions from across Australia. • Two multiplex reactions were developed comprising a total of 16 EST-SSR markers. All SSR markers amplified across different Cynodon species and different levels of ploidy. The number of alleles ranged from one to eight per locus and the total number of alleles for the germplasm collection was 79. • The 16 markers show sufficient variation for the characterization of Cynodon core collections and analysis of population genetic diversity in Cynodon grasses.

The TSPE is represented by gneisses and Migmatites formed in the range of 1100 and 630 Ma (Preciozzi et al, in prep.) and have been intensively reworked during Rio Doce orogeny (ca. 600 Ma). Field Suspect Punta del Este (TSPE) is separated from the Neoproterozoic granitoids or granitoids by central Shear Zone Punta del Este-Cordillera represented by a thin strip of mylonite s and gneisses mylonitic able to anatexis. Granitoids are sub alkaline trend throughout of this guideline. The mylonitic foliation has a general direction between N15ºE and N40ºE with sub vertical slope where development ductile quartz and muscovite bands observed (Figure 2).

  11. The mining of toxin-like polypeptides from EST database by single residue distribution analysis.

    Kozlov, Sergey; Grishin, Eugene

    2011-01-31

    Novel high throughput sequencing technologies require permanent development of bioinformatics data processing methods. Among them, rapid and reliable identification of encoded proteins plays a pivotal role. To search for particular protein families, the amino acid sequence motifs suitable for selective screening of nucleotide sequence databases may be used. In this work, we suggest a novel method for simplified representation of protein amino acid sequences named Single Residue Distribution Analysis, which is applicable both for homology search and database screening. Using the procedure developed, a search for amino acid sequence motifs in sea anemone polypeptides was performed, and 14 different motifs with broad and low specificity were discriminated. The adequacy of motifs for mining toxin-like sequences was confirmed by their ability to identify 100% toxin-like anemone polypeptides in the reference polypeptide database. The employment of novel motifs for the search of polypeptide toxins in Anemonia viridis EST dataset allowed us to identify 89 putative toxin precursors. The translated and modified ESTs were scanned using a special algorithm. In addition to direct comparison with the motifs developed, the putative signal peptides were predicted and homology with known structures was examined. The suggested method may be used to retrieve structures of interest from the EST databases using simple amino acid sequence motifs as templates. The efficiency of the procedure for directed search of polypeptides is higher than that of most currently used methods. Analysis of 39939 ESTs of sea anemone Anemonia viridis resulted in identification of five protein precursors of earlier described toxins, discovery of 43 novel polypeptide toxins, and prediction of 39 putative polypeptide toxin sequences. In addition, two precursors of novel peptides presumably displaying neuronal function were disclosed.

  14. Analysis of cassava (Manihot esculenta) ESTs: A tool for the discovery of genes

    International Nuclear Information System (INIS)

    2011-01-01

    Cassava (Manihot esculenta) is the main source of calories for more than 1,000 millions of people around the world and has been consolidated as the fourth most important crop after rice, corn and wheat. Cassava is considered tolerant to abiotic and biotic stress conditions; nevertheless these characteristics are mainly present in non-commercial varieties. Genetic breeding strategies represent an alternative to introduce the desirable characteristics into commercial varieties. A fundamental step for accelerating the genetic breeding process in cassava requires the identification of genes associated to these characteristics. One rapid strategy for the identification of genes is the possibility to have a large collection of ESTs (expressed sequence tag). In this study, a complete analysis of cassava ESTs was done. The cassava ESTs represent 80,459 sequences which were assembled in a set of 29,231 unique genes (unigen), comprising 10,945 contigs and 18,286 singletones. These 29,231 unique genes represent about 80% of the genes of the cassava's genome. Between 5% and 10% of the unigenes of cassava not show similarity to any sequences present in the NCBI database and could be consider as cassava specific genes. a functional category was assigned to a group of sequences of the unigen set (29%) following the Gene Ontology Vocabulary. the molecular function component was the best represented with 43% of the sequences, followed by the biological process component (38%) and finally the cellular component with 19%. in the cassava ESTs collection, 3,709 microsatellites were identified and they could be used as molecular markers. this study represents an important contribution to the knowledge of the functional genomic structure of cassava and constitutes an important tool for the identification of genes associated to agricultural characteristics of interest that could be employed in cassava breeding programs.

    Full Text Available Abstract Background Establishing genomic resources for closely related species will provide comparative insights that are crucial for understanding diversity and variability at multiple levels of biological organization. We developed ESTs for Mexican axolotl (Ambystoma mexicanum and Eastern tiger salamander (A. tigrinum tigrinum, species with deep and diverse research histories. Results Approximately 40,000 quality cDNA sequences were isolated for these species from various tissues, including regenerating limb and tail. These sequences and an existing set of 16,030 cDNA sequences for A. mexicanum were processed to yield 35,413 and 20,599 high quality ESTs for A. mexicanum and A. t. tigrinum, respectively. Because the A. t. tigrinum ESTs were obtained primarily from a normalized library, an approximately equal number of contigs were obtained for each species, with 21,091 unique contigs identified overall. The 10,592 contigs that showed significant similarity to sequences from the human RefSeq database reflected a diverse array of molecular functions and biological processes, with many corresponding to genes expressed during spinal cord injury in rat and fin regeneration in zebrafish. To demonstrate the utility of these EST resources, we searched databases to identify probes for regeneration research, characterized intra- and interspecific nucleotide polymorphism, saturated a human – Ambystoma synteny group with marker loci, and extended PCR primer sets designed for A. mexicanum / A. t. tigrinum orthologues to a related tiger salamander species. Conclusions Our study highlights the value of developing resources in traditional model systems where the likelihood of information transfer to multiple, closely related taxa is high, thus simultaneously enabling both laboratory and natural history research.

    Le big bang n'est pas une théorie comme les autres. Ce n'est d'ailleurs pas une théorie physique au sens propre du terme, mais un scénario cosmologique issu des équations de la relativité générale. Il est le modèle qui s'ajuste le mieux aux observations actuelles, mais à quel prix ? Il nous livre un Univers composé à 96 % de matière et d'énergie noires inconnues. C'est donc un euphémisme que de dire que le big bang semble poser autant - sinon plus - de questions qu'il n'en résout. En ce sens, le big bang apparaît davantage comme une paramétrisation de notre ignorance plutôt que comme une modélisation d'un phénomène. Pourtant, le succès du big bang et l'adhésion qu'il suscite, tant dans la sphère scientifique que dans la sphère médiatique, ne se démentent pas. Surmédiatisé, son statut dépasse celui de modèle théorique, et la simple évocation de son nom suffit pour justifier des opérations de marketing scientifique ou rejeter des cosmologies alternatives.

    Full Text Available ¿Cómo opera el proceso del gusto y de la emoción estética en la disgregación entre el sujeto y el objeto posmodernos? La pluralidad, la heterogeneidad y lo multi-procesal conforman el corpus del juicio de gusto actual. Su resultado es la construcción de otros tipos de figuras del mundo, nuevas imágenes de lo real, diversas y distintas, creadas a partir no de la unidad y universalidad del placer estético clásico y dieciochesco, sino por medio de una emoción intersubjetiva y multiforme. El gusto es víctima del tiempo. De lo interesante estético burgués se ha pasado a lo impactante y espectacularizado posindustrial. Entonces, lo light, la alta costura, el turismo, el “mundo del arte”, la word music, la publicidad, los diseños del hogar, la farándula, los artistas jet, la literatura de autoayuda y de intimidades de famosos son las nuevas esferas de un gusto que ha puesto contra la pared todas las antiguas competencias de críticos de arte modernos y del público lector ilustrado en general. ¿Qué tipo de gusto actualmente ejercitamos?, o bien, ¿de qué manera hemos mutado el juicio de gusto en disgusto fragmentado, indescible, descentrado? Este ensayo contribuye a dar algunas respuestas a estos interrogantes.

    Soares Ademilson EE

    2004-11-01

    Full Text Available Abstract Background The ongoing efforts to sequence the honey bee genome require additional initiatives to define its transcriptome. Towards this end, we employed the Open Reading frame ESTs (ORESTES strategy to generate profiles for the life cycle of Apis mellifera workers. Results Of the 5,021 ORESTES, 35.2% matched with previously deposited Apis ESTs. The analysis of the remaining sequences defined a set of putative orthologs whose majority had their best-match hits with Anopheles and Drosophila genes. CAP3 assembly of the Apis ORESTES with the already existing 15,500 Apis ESTs generated 3,408 contigs. BLASTX comparison of these contigs with protein sets of organisms representing distinct phylogenetic clades revealed a total of 1,629 contigs that Apis mellifera shares with different taxa. Most (41% represent genes that are in common to all taxa, another 21% are shared between metazoans (Bilateria, and 16% are shared only within the Insecta clade. A set of 23 putative genes presented a best match with human genes, many of which encode factors related to cell signaling/signal transduction. 1,779 contigs (52% did not match any known sequence. Applying a correction factor deduced from a parallel analysis performed with Drosophila melanogaster ORESTES, we estimate that approximately half of these no-match ESTs contigs (22% should represent Apis-specific genes. Conclusions The versatile and cost-efficient ORESTES approach produced minilibraries for honey bee life cycle stages. Such information on central gene regions contributes to genome annotation and also lends itself to cross-transcriptome comparisons to reveal evolutionary trends in insect genomes.

    Euphorbiaceae represents flowering plants family of tropical and sub-tropical region rich in secondary metabolites of economic importance. To understand and assess the genetic makeup among the members, this study was undertaken to characterize and compare SSR markers from publicly available ESTs and GSSs of nine selected species of the family. Mining of SSRs was performed by MISA, primer designing by Primer3, while functional annotation, gene ontology (GO) and enrichment analysis were performed by Blast2GO. A total 12,878 number of SSRs were detected from 101,701 number of EST sequences. SSR density ranged from 1 SSR/3.22 kb to 1 SSR/15.65 kb. A total of 1873 primer pairs were designed for the annotated SSR-Contigs. About 77.07% SSR-ESTs could be assigned a significant match to the protein database. 3037 unique SSR-FDM were assigned and IPR003657 (WRKY Domain) was found to be the most dominant FDM among the members. 1810 unique GO terms obtained were further subjected to enrichment analysis to obtain 513 statistically significant GO terms mapped to the SSR containing ESTs. Most frequent enriched GO terms were, GO:0003824 for molecular function, GO:0006350 for biological process and GO:0005886 for cellular component, justifying the richness of defensive secondary metabolites and phytomedicine within the family. The results from this study provides tangible insight to genetic make-up and distribution of SSRs. Functional annotation corresponded many genes of unknown functions which may be considered as novel genes or genes responsible for stress specific secondary metabolites. Further studies are required to understand stress specific genes accountable for leveraging the synthesis of secondary metabolites.

    With the aim to increase the number of functional markers in resource poor crop like cultivated peanut (Arachis hypogaea), large numbers of available expressed sequence tags (ESTs) in the public databases, were employed for the development of novel EST derived simple sequence repeat (SSR) markers. From 16424 unigenes, 2784 (16.95%) SSRs containing unigenes having 3373 SSR motifs were identified. Of these, 2027 (72.81%) sequences were annotated and 4124 gene ontology terms were assigned. Among different SSR motif-classes, tri-nucleotide repeats (33.86%) were the most abundant followed by di-nucleotide repeats (27.51%) while AG/CT (20.7%) and AAG/CTT (13.25%) were the most abundant repeat-motifs. A total of 2456 EST-SSR novel primer pairs were designed, of which 366 unigenes having relevance to various stresses and other functions, were PCR validated using a set of 11 diverse peanut genotypes. Of these, 340 (92.62%) primer pairs yielded clear and scorable PCR products and 39 (10.66%) primer pairs exhibited polymorphisms. Overall, the number of alleles per marker ranged from 1-12 with an average of 3.77 and the PIC ranged from 0.028 to 0.375 with an average of 0.325. The identified EST-SSRs not only enriched the existing molecular markers kitty, but would also facilitate the targeted research in marker-trait association for various stresses, inter-specific studies and genetic diversity analysis in peanut.

La narración plantea una lógica en la que la basura, en lugar de constituirse en un indicio que posibilite la reconstrucción del paisaje social, exhibe lo desbordante, lo inasimilable y los vacíos de sentido. En el mundo que nos presenta Busqued lo viviente se vuelve resto en la medida en que encarna una heterogeneidad irreductible a cualquier estructura social y productiva. This paper analyzes the way in which Carlos Busqued's novel Bajo este sol tremendo (2009 is based on the representation of discarded lives, garbage, and all kinds of remains and thus proposes a tension between order and excess. The narration raises a logic in which garbage, instead of constituting an indicator that allows for the reconstruction of the social landscape, exhibits the overflowing, the unassimilable, and the voids of meaning. In the world that Busqued presents, the living becomes a remainder because it embodies an irreducible heterogeneity with regards to any social and productive structure.

    Full Text Available El argumento más conocido en favor del innatismo de ciertas estructuras mentales sigue siendo el ‘Argumento de la Pobreza del estímulo’ (APE. La idea general del APE es que el conocimiento que se requiere para desarrollar una cierta capacidad cognitiva excede en gran medida la información disponible en el entorno, de manera que el organismo contribuye con información innata. Un examen de la literatura del APE lingüístico muestra que aún no está del todo claro qué clase de argumento es y lo que realmente muestra. Mi objetivo en este trabajo es ofrecer un diagnóstico de la estrategia innatista que utiliza el APE. Así, distingo tres tipos de APE y argumento, en primer lugar, que la versión más apropiada, según ciertos criterios empíricos y teóricos, no parece ser suficiente para el innatismo lingüístico y, en segundo lugar, que para ser suficiente, suele complementarse con un argumento ‘de sillón’, cuya consecuencia es que convierte al innatismo en una hipótesis empírica debilitada.

    Full Text Available Abstract Background Norway spruce is widely distributed across Europe and the predominant tree of the Alpine region. Fast growth and the fact that timber can be harvested cost-effectively in relatively young populations define its status as one of the economically most important tree species of Northern Europe. In this study, EST derived simple sequence repeat (SSR markers were developed for the assessment of putative functional diversity in Austrian Norway spruce stands. Results SSR sequences were identified by analyzing 14,022 publicly available EST sequences. Tri-nucleotide repeat motifs were most abundant in the data set followed by penta- and hexa-nucleotide repeats. Specific primer pairs were designed for sixty loci. Among these, 27 displayed polymorphism in a testing population of 16 P. abies individuals sampled across Austria and in an additional screening population of 96 P. abies individuals from two geographically distinct Austrian populations. Allele numbers per locus ranged from two to 17 with observed heterozygosity ranging from 0.075 to 0.99. Conclusions We have characterized variable EST SSR markers for Norway spruce detected in expressed genes. Due to their moderate to high degree of variability in the two tested screening populations, these newly developed SSR markers are well suited for the analysis of stress related functional variation present in Norway spruce populations.

    Full Text Available Premise of the study: Simple sequence repeat markers were developed based on expressed sequence tags (EST-SSR and screened for polymorphism among 23 Pisum sativum individuals to assist development and refinement of pea linkage maps. In particular, the SSR markers were developed to assist in mapping of white mold disease resistance quantitative trait loci. Methods and Results: Primer pairs were designed for 46 SSRs identified in EST contiguous sequences assembled from a 454 pyrosequenced transcriptome of the pea cultivar, ‘LIFTER’. Thirty-seven SSR markers amplified PCR products, of which 11 (30% SSR markers produced polymorphism in 23 individuals, including parents of recombinant inbred lines, with two to four alleles. The observed and expected heterozygosities ranged from 0 to 0.43 and from 0.31 to 0.83, respectively. Conclusions: These EST-SSR markers for pea will be useful for refinement of pea linkage maps, and will likely be useful for comparative mapping of pea and as tools for marker-based pea breeding.

    Foxtail millet is a gramineous crop with low water requirement. Despite its high water use efficiency, less attention has been paid to the molecular genetics of foxtail millet. This article reports the construction of subtracted cDNA libraries from foxtail millet seedlings under dehydration stress and the expression profile analysis of 1947 UniESTs from the subtracted cDNA libraries by a cDNA microarray. The results showed that 95 and 57 ESTs were upregulated by dehydration stress, respectively, in roots and shoots of seedlings and that 10 and 27 ESTs were downregulated, respectively, in roots and shoots. The expression profile analysis showed that genes induced in foxtail millet roots were different from those in shoots during dehydration stress and that the early response to dehydration stress in foxtail millet roots was the activation of the glycolysis metabolism. Moreover, protein degradation pathway may also play a pivotal role in drought-tolerant responses of foxtail millet. Finally, Northern blot analysis validated well the cDNA microarray data.

    The adzuki bean (Vigna angularis (Ohwi) Ohwi and Ohashi) is an important grain legume of Asia. It is cultivated mainly in China, Japan and Korea. Despite its importance, few genomic resources are available for molecular genetic research of adzuki bean. In this study, we developed EST-SSR markers for the adzuki bean through next-generation sequencing. More than 112 million high-quality cDNA sequence reads were obtained from adzuki bean using Illumina paired-end sequencing technology, and the sequences were de novo assembled into 65,950 unigenes. The average length of the unigenes was 1,213 bp. Among the unigenes, 14,547 sequences contained a unique simple sequence repeat (SSR) and 3,350 sequences contained more than one SSR. A total of 7,947 EST-SSRs were identified as potential molecular markers, with mono-nucleotide A/T repeats (99.0%) as the most abundant motif class, followed by AG/CT (68.4%), AAG/CTT (30.0%), AAAG/CTTT (26.2%), AAAAG/CTTTT (16.1%), and AACGGG/CCCGTT (6.0%). A total of 500 SSR markers were randomly selected for validation, of which 296 markers produced reproducible amplicons with 38 polymorphic markers among the 32 adzuki bean genotypes selected from diverse geographical locations across China. The large number of SSR-containing sequences and EST-SSR markers will be valuable for genetic analysis of the adzuki bean and related Vigna species.

    2009-03-01

    Full Text Available Abstract Background The pituitary is a critical neuroendocrine gland that is comprised of five hormone-secreting cell types, which develops in tandem during the embryonic stage. Some essential genes have been identified in the early stage of adenohypophysial development, such as PITX1, FGF8, BMP4 and SF-1. However, it is likely that a large number of signaling molecules and transcription factors essential for determination and terminal differentiation of specific cell types remain unidentified. High-throughput methods such as microarray analysis may facilitate the measurement of gene transcriptional levels, while Expressed sequence tag (EST sequencing, an efficient method for gene discovery and expression level analysis, may no-redundantly help to understand gene expression patterns during development. Results A total of 9,271 ESTs were generated from both fetal and adult pituitaries, and assigned into 961 gene/EST clusters in fetal and 2,747 in adult pituitary by homology analysis. The transcription maps derived from these data indicated that developmentally relevant genes, such as Sox4, ST13 and ZNF185, were dominant in the cDNA library of fetal pituitary, while hormones and hormone-associated genes, such as GH1, GH2, POMC, LHβ, CHGA and CHGB, were dominant in adult pituitary. Furthermore, by using RT-PCR and in situ hybridization, Sox4 was found to be one of the main transcription factors expressed in fetal pituitary for the first time. It was expressed at least at E12.5, but decreased after E17.5. In addition, 40 novel ESTs were identified specifically in this tissue. Conclusion The significant changes in gene expression in both tissues suggest a distinct and dynamic switch between embryonic and adult pituitaries. All these data along with Sox4 should be confirmed to further understand the community of multiple signaling pathways that act as a cooperative network that regulates maturation of the pituitary. It was also suggested that EST

Los resultados obtenidos con las cuatro poblaciones se comparan empleando tres indicadores: diferencia entre las tasas de 1992 y 1971, razón entre las tasas de 1992 y 1971y cambio anual porcentual entre 1971 y 1992. RESULTADOS: En la mayor parte de las causas de muerte estudiadas incluyendo el total de causas, la cardiopatía isquémica y casi todos los tumores, la razón de tasas y el porcentaje de cambio anual son similares con independencia de cuál sea la población estándar empleada. En cambio, la diferencia de tasas es muy diferente en función de la población de referencia. En las enfermedades infecciosas y el cáncer de testículo se produce la situación contraria: la diferencia de tasas es robusta mientras que la razón de tasas varía con la población estándar. Finalmente, la mortalidad por neumonía, enfermedad de Parkinson y cáncer de encéfalo muestra cambios en los tres indicadores utilizados. CONCLUSIONES: Es necesario realizar un análisis de las tasas específicas por edad antes de proceder a su ajuste. Este análisis permite averiguar si el ajuste por edades es correcto y qué indicador (diferencia, razón o cambio porcentual será adecuado para realizar comparaciones.

    Full Text Available Abstract Background Expressed Sequence Tag (EST sequences are widely used in applications such as genome annotation, gene discovery and gene expression studies. However, some of GenBank dbEST sequences have proven to be “unclean”. Identification of cDNA termini/ends and their structures in raw ESTs not only facilitates data quality control and accurate delineation of transcription ends, but also furthers our understanding of the potential sources of data abnormalities/errors present in the wet-lab procedures for cDNA library construction. Results After analyzing a total of 309,976 raw Pinus taeda ESTs, we uncovered many distinct variations of cDNA termini, some of which prove to be good indicators of wet-lab artifacts, and characterized each raw EST by its cDNA terminus structure patterns. In contrast to the expected patterns, many ESTs displayed complex and/or abnormal patterns that represent potential wet-lab errors such as: a failure of one or both of the restriction enzymes to cut the plasmid vector; a failure of the restriction enzymes to cut the vector at the correct positions; the insertion of two cDNA inserts into a single vector; the insertion of multiple and/or concatenated adapters/linkers; the presence of 3′-end terminal structures in designated 5′-end sequences or vice versa; and so on. With a close examination of these artifacts, many problematic ESTs that have been deposited into public databases by conventional bioinformatics pipelines or tools could be cleaned or filtered by our methodology. We developed a software tool for Abnormality Filtering and Sequence Trimming for ESTs (AFST, http://code.google.com/p/afst/ using a pattern analysis approach. To compare AFST with other pipelines that submitted ESTs into dbEST, we reprocessed 230,783 Pinus taeda and 38,709 Arachis hypogaea GenBank ESTs. We found 7.4% of Pinus taeda and 29.2% of Arachis hypogaea GenBank ESTs are “unclean” or abnormal, all of which could be cleaned

    Full Text Available Os estudantes de graduação do curso de Psicologia do Instituto de Psicologia da Universidade de São Paulo, ao cursarem as disciplinas relacionadas à área da Psicologia Escolar, realizam estágios em instituições educativas. Imbuídos de uma postura crítica, os estagiários entram em contato com demandas de tratamento, prevenção e adaptação e compreendem a produção histórica destas. Todavia, em muitos momentos, os estagiários julgam essas demandas como se fossem equivocadas e, dessa forma, não conseguem perceber a multiplicidade de elementos que as constituem e as formas para agir em sua produção. O objetivo deste artigo é apresentar um percurso de trabalho enfatizando as estratégias criadas para dar conta de um dos desafios que se apresentam no grupo de supervisão: intervir nesse momento no qual os estagiários consideram o funcionamento da escola como algo exterior a eles. As estratégias criadas indicam que a desconstrução necessária na formação dos estudantes de Psicologia para que aprendam a intervir nos processos institucionais vividos durante os estágios requer, também, a desconstrução de uma forma de pensar que cria um suposto sujeito fora do diagrama de forças em que o processo do estágio faz parte.

    This communication presents a prototype image slicer for the 4-m European Solar Telescope (EST) designed for the spectrograph of the 1.5-m GREGOR solar telescope (GRIS). The design of this integral field unit has been called MuSICa (Multi-Slit Image slicer based on collimator-Camera). It is a telecentric system developed specifically for the integral field, high resolution spectrograph of EST and presents multi-slit capability, reorganizing a bidimensional field of view of 80 arcsec^{2} into 8 slits, each one of them with 200 arcsec length × 0.05 arcsec width. It minimizes the number of optical components needed to fulfil this multi-slit capability, three arrays of mirrors: slicer, collimator and camera mirror arrays (the first one flat and the other two spherical). The symmetry of the layout makes it possible to overlap the pupil images associated to each part of the sliced entrance field of view. A mask with only one circular aperture is placed at the pupil position. This symmetric characteristic offers some advantages: facilitates the manufacturing process, the alignment and reduces the costs. In addition, it is compatible with two modes of operation: spectroscopic and spectro-polarimetric, offering a great versatility. The optical quality of the system is diffraction-limited. The prototype will improve the performances of GRIS at GREGOR and is part of the feasibility study of the integral field unit for the spectrographs of EST. Although MuSICa has been designed as a solar image slicer, its concept can also be applied to night-time astronomical instruments (Collados et al. 2010, Proc. SPIE, Vol. 7733, 77330H; Collados et al. 2012, AN, 333, 901; Calcines et al. 2010, Proc. SPIE, Vol. 7735, 77351X)

  5. Para una ética y una estética del software libre

    Full Text Available This paper deals with how an emergent community like hacker´s has developed a code of aestehtic and ethical values in different levels. The history of hackerism is a previous step to understand in a very basic way how code writing has forked in two different paths: free software and open code. Aesthetics can be a way to correlate creative work made by hackers and how avant-garde movements considered their work. From an ethical point of view it is difficult to find an unified agenda for all the different groups involved with free and open software. But this movement represents the emergence of a new ethical approach, retaking older attitudes like the commons.

    El presente artículo estudia el modo en que la comunidad hacker ha desarrollado un código propio de valores estéticos y éticos. La historia del «hackerismo » supone un paso previo para la comprensión de cómo la escritura de código se ha bifurcado en dos líneas: el software libre y el código abierto. El estudio de las dimensiones estéticas de estos movimientos puede resultar muy provechoso para correlacionar el trabajo creativo de los hackers y la manera en que éste es considerado por los movimientos de vanguardia. Desde un punto de vista ético, es difícil definir un proyecto común a todos los grupos implicados. Sin embargo, este movimiento representa, en su conjunto, la emergencia de una nueva perspectiva ética que retoma viejas ideas como la del procomún.

    Full Text Available Abstract Background The southern cattle tick, Rhipicephalus (Boophilus microplus, is an economically important parasite of cattle and can transmit several pathogenic microorganisms to its cattle host during the feeding process. Understanding the biology and genomics of R. microplus is critical to developing novel methods for controlling these ticks. Results We present a global comparative genomic analysis of a gene index of R. microplus comprised of 13,643 unique transcripts assembled from 42,512 expressed sequence tags (ESTs, a significant fraction of the complement of R. microplus genes. The source material for these ESTs consisted of polyA RNA from various tissues, lifestages, and strains of R. microplus, including larvae exposed to heat, cold, host odor, and acaricide. Functional annotation using RPS-Blast analysis identified conserved protein domains in the conceptually translated gene index and assigned GO terms to those database transcripts which had informative BlastX hits. Blast Score Ratio and SimiTri analysis compared the conceptual transcriptome of the R. microplus database to other eukaryotic proteomes and EST databases, including those from 3 ticks. The most abundant protein domains in BmiGI were also analyzed by SimiTri methodology. Conclusion These results indicate that a large fraction of BmiGI entries have no homologs in other sequenced genomes. Analysis with the PartiGene annotation pipeline showed 64% of the members of BmiGI could not be assigned GO annotation, thus minimal information is available about a significant fraction of the tick genome. This highlights the important insights in tick biology which are likely to result from a tick genome sequencing project. Global comparative analysis identified some tick genes with unexpected phylogenetic relationships which detailed analysis attributed to gene losses in some members of the animal kingdom. Some tick genes were identified which had close orthologues to mammalian genes

    Full Text Available Abstract Background The western African clawed frog Xenopus tropicalis is an anuran amphibian species now used as model in vertebrate comparative genomics. It provides the same advantages as Xenopus laevis but is diploid and has a smaller genome of 1.7 Gbp. Therefore X. tropicalis is more amenable to systematic transcriptome surveys. We initiated a large-scale partial cDNA sequencing project to provide a functional genomics resource on genes expressed in the nervous system during early embryogenesis and metamorphosis in X. tropicalis. Results A gene index was defined and analysed after the collection of over 48,785 high quality sequences. These partial cDNA sequences were obtained from an embryonic head and retina library (30,272 sequences and from a metamorphic brain and spinal cord library (27,602 sequences. These ESTs are estimated to represent 9,693 transcripts derived from an estimated 6,000 genes. Comparison of these cDNA sequences with protein databases indicates that 46% contain their start codon. Further annotation included Gene Ontology functional classification, InterPro domain analysis, alternative splicing and non-coding RNA identification. Gene expression profiles were derived from EST counts and used to define transcripts specific to metamorphic stages of development. Moreover, these ESTs allowed identification of a set of 225 polymorphic microsatellites that can be used as genetic markers. Conclusion These cDNA sequences permit in silico cloning of numerous genes and will facilitate studies aimed at deciphering the roles of cognate genes expressed in the nervous system during neural development and metamorphosis. The genomic resources developed to study X. tropicalis biology will accelerate exploration of amphibian physiology and genetics. In particular, the model will facilitate analysis of key questions related to anuran embryogenesis and metamorphosis and its associated regulatory processes.

    We identified and characterized EST-SSRs with strong discrimination power against Lavandula angustifolia and Lavandula x intermedia . The markers also showed considerable cross-species transferability rate into six related Lavandula species. Lavenders (Lavandula) are important economical crops grown around the globe for essential oil production. In an attempt to develop genetic markers for these plants, we analyzed over 13,000 unigenes developed from L. angustifolia and L. x intermedia EST databases, and identified 3,459 simple sequence repeats (SSR), which were dominated by trinucleotides (41.2 %) and dinucleotides (31.45 %). Approximately, 19 % of the unigenes contained at least one SSR marker, over 60 % of which were localized in the UTRs. Only 252 EST-SSRs were 18 bp or longer from which 31 loci were validated, and 24 amplified discrete fragments with 85 % polymorphism in L. x intermedia and L. angustifolia. The average number of alleles in L. x intermedia and L. angustifolia were 3.42 and 3.71 per marker with average PIC values of 0.47 and 0.52, respectively. These values suggest a moderate to strong level of informativeness for the markers, with some loci producing unique fingerprints. The cross-species transferability rate of the markers ranges 50-100 % across eight species. The utility of these markers was assessed in eight Lavandula species and 15 L. angustifolia and L. x intermedia cultivars, and the dendrogram deduced from their similarity indexes successfully delineated the species into their respective sections and the cultivars into their respective species. These markers have potential for application in fingerprinting, diversity studies and marker-assisted breeding of Lavandula.

    Full Text Available El frecuente hallazgo de restos humanos desarticulados y dispersos en sitios de la región Este del territorio uruguayo da lugar a la necesidad de recurrir en muchos casos a métodos alternativos de determinación de sexo, basados en análisis discriminantes. Las muestras de las que se parte en estos análisis son ya de poblaciones actuales, ya de poblaciones prehistóricas distintas a las representadas en el registro arqueológico uruguayo. Al determinar el número mínimo de individuos de un conjunto disperso, la edad y el sexo de los individuos representados cobran gran utilidad, y la precisión de los métodos de determinación de sexo basados en piezas aisladas se vuelve crucial. Este trabajo presenta la evaluación de 24 ecuaciones discriminantes canónicas sobre medidas de 7 huesos, en una muestra arqueológica de 15 individuos de dos sitios con estructuras monticulares ("cerritos de indios" del Este Uruguayo. El sexo de los esqueletos fue determinado anteriormente mediante métodos basados en la pelvis, el cráneo, o ambos. Los métodos evaluados presentaron grados de exactitud general de entre el 30 y el 100 por ciento, sin una dirección particular en los errores de clasificación. Esto pone de relieve la necesidad de revisar las ecuaciones utilizadas, recurriendo ya sea a una reelaboración de los coeficientes utilizados, o a un desplazamiento de los puntos de corte.

    2009-01-01

    Background The globe artichoke (Cynara cardunculus var. scolymus L.) is a significant crop in the Mediterranean basin. Despite its commercial importance and its both dietary and pharmaceutical value, knowledge of its genetics and genomics remains scant. Microsatellite markers have become a key tool in genetic and genomic analysis, and we have exploited recently acquired EST (expressed sequence tag) sequence data (Composite Genome Project - CGP) to develop an extensive set of microsatellite markers. Results A unigene assembly was created from over 36,000 globe artichoke EST sequences, containing 6,621 contigs and 12,434 singletons. Over 12,000 of these unigenes were functionally assigned on the basis of homology with Arabidopsis thaliana reference proteins. A total of 4,219 perfect repeats, located within 3,308 unigenes was identified and the gene ontology (GO) analysis highlighted some GO term's enrichments among different classes of microsatellites with respect to their position. Sufficient flanking sequence was available to enable the design of primers to amplify 2,311 of these microsatellites, and a set of 300 was tested against a DNA panel derived from 28 C. cardunculus genotypes. Consistent amplification and polymorphism was obtained from 236 of these assays. Their polymorphic information content (PIC) ranged from 0.04 to 0.90 (mean 0.66). Between 176 and 198 of the assays were informative in at least one of the three available mapping populations. Conclusion EST-based microsatellites have provided a large set of de novo genetic markers, which show significant amounts of polymorphism both between and within the three taxa of C. cardunculus. They are thus well suited as assays for phylogenetic analysis, the construction of genetic maps, marker-assisted breeding, transcript mapping and other genomic applications in the species.

    Full Text Available Resumo: O objetivo deste artigo é apontar como percursos intelectuais distintos, na primeira metade do século XX, levaram importantes nomes da teoria estética a um método marxista comum, incorporado às discussões literárias no período entreguerras. Nesse sentido, busca-se demonstrar como o período formativo mais idealista do círculo de Bakhtin e dos formalistas russos, bem como o de György Lukács e de Walter Benjamin, não impediram que suas obras culminassem numa noção mais dialética e historicizada sobre o conceito estético de realismo. Assim, buscaremos enfatizar que a ideia de uma condensação não mecânica da realidade na forma artística é a baliza central de todos esses autores, e é o que, em última instância, mais unifica que aparta suas distintas teorias. Palavras-chave: Realismo, Marxismo, Bakhtin, Lukács, Benjamin.

Na medida em que, nas sociedades ocidentais deste início de século, as dinâmicas de gênero encontram-se fortemente marcadas por códigos tecnobionormativos (conhecimentos, artefatos e tecnologias regulados por leis de propriedade intelectual e tecnológica torna-se possível o encontro entre ativismos que, em princípio, não possuíam uma plataforma comum de ação.

    The cephalochordates, commonly known as amphioxus or lancelets, are now considered the most basal chordate group, and the studies of these organisms therefore offer important insights into various levels of evolutionary biology. In the past two decades, the investigation of amphioxus developmental biology has provided key knowledge for understanding the basic patterning mechanisms of chordates. Comparative genome studies of vertebrates and amphioxus have uncovered clear evidence supporting the hypothesis of two-round whole-genome duplication thought to have occurred early in vertebrate evolution and have shed light on the evolution of morphological novelties in the complex vertebrate body plan. Complementary to the amphioxus genome-sequencing project, a large collection of expressed sequence tags (ESTs) has been generated for amphioxus in recent years; this valuable collection represents a rich resource for gene discovery, expression profiling and molecular developmental studies in the amphioxus model. Here, we review previous EST analyses and available cDNA resources in amphioxus and discuss their value for use in evolutionary and developmental studies. We also discuss the potential advantages of applying high-throughput, next-generation sequencing (NGS) technologies to the field of amphioxus research.

    O objetivo deste trabalho é analisar a construção literária de Camões na obra Que farei com este livro?, de José Saramago. Por causa da dificuldade em publicar sua obra máxima, Os Lusíadas, Camões percorre as diversas instâncias portuguesas no intuito de conseguir dar concretude ao seu trabalho de anos no exílio. Recorrendo a aspectos históricos e lacunas sobre a biografia de Camões, Saramago cria uma obra que mostra a inércia que reinava em Portugal após as grandes conquistas. Obra de contraponto entre o passado e o presente, Que farei com este livro? representa uma importante reflexão sobre o papel do escritor e seus desafios em momentos de decadência.

    Full Text Available 17823 is a frequent site of gene amplification in breast cancer. Several lines of evidence suggest the presence of multiple amplicons on 17823. To characterize distinct amplicons on 17823 and localize putative oncogenes, we screened genes and expressed sequence tags (ESTs in existing physical and radiation hybrid maps for amplification and overexpression in breast cancer cell lines by semiquantitative duplex PCR, semiquantitative duplex RT-PCR, Southern blot, Northern blot analyses. We identified two distinct amplicons on 17823, one including TBX2 and another proximal region including RPS6KB1 (PS6K and MUL. In addition to these previously reported overexpressed genes, we also identified amplification and overexpression of additional uncharacterized genes and ESTs, some of which suggest potential oncogenic activity. In conclusion, we have further defined two distinct regions of gene amplification and overexpression on 17823 with identification of new potential oncogene candidates. Based on the amplification and overexpression patterns of known and as of yet unrecognized genes on 17823, it is likely that some of these genes mapping to the discrete amplicons function as oncogenes and contribute to tumor progression in breast cancer cells.

    The development of genetic tools for non-model organisms has been hampered by cost, but advances in next-generation sequencing (NGS) have created new opportunities. In ecological research, this raises the prospect for developing molecular markers to simultaneously study important genetic processes such as gene flow in multiple non-model plant species within complex natural and anthropogenic landscapes. Here, we report the use of bar-coded multiplexed paired-end Illumina NGS for the de novo development of expressed sequence tag-derived simple sequence repeat (EST-SSR) markers at low cost for a range of 24 tree species. Each chosen tree species is important in complex tropical agroforestry systems where little is currently known about many genetic processes. An average of more than 5,000 EST-SSRs was identified for each of the 24 sequenced species, whereas prior to analysis 20 of the species had fewer than 100 nucleotide sequence citations. To make results available to potential users in a suitable format, we have developed an open-access, interactive online database, tropiTree (http://bioinf.hutton.ac.uk/tropiTree), which has a range of visualisation and search facilities, and which is a model for the efficient presentation and application of NGS data.

    Full Text Available ABSTRACT: The Uruguayan continental margin was generated as the result of the breakup of Gondwana and, later, the opening of the South Atlantic Ocean, which began in the Jurassic. Three major areas of Meso-Cenozoic sedimentation are located in the Uruguayan offshore: the Punta del Este Basin, the southernmost sector of the Pelotas Basin and the Oriental del Plata Basin. These basins share the classical stages of tectono-sedimentary evolution of the other Atlantic basins, including the prerift (Paleozoic, rift (Jurassic-Early Cretaceous, transition (Barremian-Aptian and postrift (Aptian-present phases. Based on the analysis of basin evolution through seismic sections and well data as well as on the establishment of analogies with productive Atlantic basins, four speculative petroleum systems are proposed for the Punta del Este Basin: 1 Marine petroleum system of the prerift stage: Devonian/Permian-Devonian/Permian(?, 2 Lacustrine petroleum system of the synrift stage: Neocomian-Neocomian(?, 3 Marine petroleum system of the Cretaceous postrift: Aptian-Late Cretaceous(?, 4 Marine petroleum system of the Cenozoic postrift: Paleocene-Paleogene/Neogene(?.

    In barley, breeding using good genetic characteristics can improve the quality or quantity of crop characters from one generation to the next generation. The development of effective molecular markers in barley is crucial for understanding and analyzing the diversity of useful alleles. In this study, we conducted genetic relationship analysis using expressed sequence tag-simple sequence repeat (EST-SSR) markers for barley identification and assessment of barley cultivar similarity. Seeds from 82 cultivars, including 31 each of naked and hulled barley from the Korea Seed and Variety Service and 20 of malting barley from the RDA-Genebank Information Center, were analyzed in this study. A cDNA library of the cultivar Gwanbori was constructed for use in analysis of genetic relationships, and 58 EST-SSR markers were developed and characterized. In total, 47 SSR markers were employed to analyze polymorphisms. A relationship dendrogram based on the polymorphism data was constructed to compare genetic diversity. We found that the polymorphism information content among the examined cultivars was 0.519, which indicates that there is low genetic diversity among Korean barley cultivars. The results obtained in this study may be useful in preventing redundant investment in new cultivars and in resolving disputes over seed patents. Our approach can be used by companies and government groups to develop different cultivars with distinguishable markers. In addition, the developed markers can be used for quantitative trait locus analysis to improve both the quantity and the quality of cultivated barley.

    Full Text Available Simple sequence repeats (SSRs are among the most important markers for population analysis and have been widely used in plant genetic mapping and molecular breeding. Expressed sequence tag-SSR (EST-SSR markers, located in the coding regions, are potentially more efficient for QTL mapping, gene targeting, and marker-assisted breeding. In this study, we investigated 51,694 nonredundant unigenes, assembled from clean reads from deep transcriptome sequencing with a Solexa/Illumina platform, for identification and development of EST-SSRs in Chinese cabbage. In total, 10,420 EST-SSRs with over 12 bp were identified and characterized, among which 2744 EST-SSRs are new and 2317 are known ones showing polymorphism with previously reported SSRs. A total of 7877 PCR primer pairs for 1561 EST-SSR loci were designed, and primer pairs for twenty-four EST-SSRs were selected for primer evaluation. In nineteen EST-SSR loci (79.2%, amplicons were successfully generated with high quality. Seventeen (89.5% showed polymorphism in twenty-four cultivars of Chinese cabbage. The polymorphic alleles of each polymorphic locus were sequenced, and the results showed that most polymorphisms were due to variations of SSR repeat motifs. The EST-SSRs identified and characterized in this study have important implications for developing new tools for genetics and molecular breeding in Chinese cabbage.

    Full Text Available A novel esterase, MtEst45, was isolated from a fosmid genomic library of Microbulbifer thermotolerans DAU221. The encoding gene is predicted to have a mass of 45,564 Da and encodes 495 amino acids, excluding a 21 amino acid signal peptide. MtEst45 showed a low amino acid identity (approximately 23–24% compared with other lipolytic enzymes belonging to Family III, a closely related bacterial lipolytic enzyme family. MtEst45 also showed a conserved GXSXG motif, G131IS133YG135, which was reported as active site of known lipolytic enzymes, and the putative catalytic triad composed of D237 and H265. Because these mutants of MtEst45, which was S133A, D237N, and H265L, had no activity, these catalytic triad essential for the enzyme catalysis. MtEst45 was overexpressed in Escherichia coli BL21 (DE3 and purified via His-tag affinity chromatography. The optimal pH and temperature of MtEst45 were estimated to be 8.17 and 46.27°C by response surface methodology, respectively. Additionally, MtEst45 was also active between 1–15°C. The optimal hydrolysis substrate for MtEst45 among p-nitrophenyl esters (C2–C18 was p-nitrophenyl butyrate, and the Km and Vmax values were 0.0998 mM and 550 μmol/min/mg of protein, respectively. MtEst45 was strongly inhibited by Hg2+, Zn2+, and Cu2+ ions; by phenylmethanesulfonyl fluoride; and by β-mercaptoethanol. Ca2+ did not affect the enzyme’s activity. These biochemical properties, sequence identity, and phylogenetic analysis suggest that MtEst45 represents a novel and valuable bacterial lipolytic enzyme family and is useful for biotechnological applications.

    2011-06-01

    Full Text Available Abstract Background Colletotrichum truncatum is a haploid, hemibiotrophic, ascomycete fungal pathogen that causes anthracnose disease on many economically important leguminous crops. This pathogen exploits sequential biotrophic- and necrotrophic- infection strategies to colonize the host. Transition from biotrophy to a destructive necrotrophic phase called the biotrophy-necrotrophy switch is critical in symptom development. C. truncatum likely secretes an arsenal of proteins that are implicated in maintaining a compatible interaction with its host. Some of them might be transition specific. Results A directional cDNA library was constructed from mRNA isolated from infected Lens culinaris leaflet tissues displaying the biotrophy-necrotrophy switch of C. truncatum and 5000 expressed sequence tags (ESTs with an average read of > 600 bp from the 5-prime end were generated. Nearly 39% of the ESTs were predicted to encode proteins of fungal origin and among these, 162 ESTs were predicted to contain N-terminal signal peptides (SPs in their deduced open reading frames (ORFs. The 162 sequences could be assembled into 122 tentative unigenes comprising 32 contigs and 90 singletons. Sequence analyses of unigenes revealed four potential groups: hydrolases, cell envelope associated proteins (CEAPs, candidate effectors and other proteins. Eleven candidate effector genes were identified based on features common to characterized fungal effectors, i.e. they encode small, soluble (lack of transmembrane domain, cysteine-rich proteins with a putative SP. For a selected subset of CEAPs and candidate effectors, semiquantitative RT-PCR showed that these transcripts were either expressed constitutively in both in vitro and in planta or induced during plant infection. Using potato virus X (PVX based transient expression assays, we showed that one of the candidate effectors, i. e. contig 8 that encodes a cerato-platanin (CP domain containing protein, unlike CP proteins

    EVER-EST (European Virtual Environment for Research - Earth Science Themes) is an European H2020 project (2015-2018) aimed at the creation of a Virtual Research Environment (VRE) for the Earth Sciences. The VRE is intended to enhance the ability to collaborate and share knowledge and experience among scientists. One of the innovations of the project is the exploitation of the "Research Object" concept (http://www.rohub.org). Research Objects encapsulate not only data and publications, but also algorithms, codes, results, and workflows that can be stored, shared and re-used. Four scientific communities are involved in the EVER-EST project: land monitoring, natural hazards, marine biology, and the GEO Geohazard Supersites community (http://www.earthobservations.org/gsnl.php). The latter is represented in the project by INGV and the University of Iceland, and has provided user requirements to tailor the VRE to the common needs of the worldwide Supersite communities. To develop and test the VRE we have defined user scenarios and created Research Objects embedding research activities and workflows on the Permanent Supersites Campi Flegrei, Mount Etna and Icelandic Volcanoes (http://vm1.everest.psnc.pl/supersites/). While these Supersites are test sites for the platform, during the last year of the project other Supersites may also be involved to demonstrate the added value of the collaborative environment in research activities aiming to support Disaster Risk Reduction. Using the VRE, scientists are able to collaborate with colleagues located in different parts of the world, in a simple and effective way. This includes being able to remotely access and share data, research results and ideas, to carry out training sessions and discussions, to compare different results and models, and to synthesize many different pieces of information in a single consensus product to be disseminated to end-users. In particular, a further need of the Supersite scientists, which can be

    Full Text Available Abstract Background Plants can defend themselves against herbivorous insects prior to the onset of larval feeding by responding to the eggs laid on their leaves. In the European field elm (Ulmus minor, egg laying by the elm leaf beetle ( Xanthogaleruca luteola activates the emission of volatiles that attract specialised egg parasitoids, which in turn kill the eggs. Little is known about the transcriptional changes that insect eggs trigger in plants and how such indirect defense mechanisms are orchestrated in the context of other biological processes. Results Here we present the first large scale study of egg-induced changes in the transcriptional profile of a tree. Five cDNA libraries were generated from leaves of (i untreated control elms, and elms treated with (ii egg laying and feeding by elm leaf beetles, (iii feeding, (iv artificial transfer of egg clutches, and (v methyl jasmonate. A total of 361,196 ESTs expressed sequence tags (ESTs were identified which clustered into 52,823 unique transcripts (Unitrans and were stored in a database with a public web interface. Among the analyzed Unitrans, 73% could be annotated by homology to known genes in the UniProt (Plant database, particularly to those from Vitis, Ricinus, Populus and Arabidopsis. Comparative in silico analysis among the different treatments revealed differences in Gene Ontology term abundances. Defense- and stress-related gene transcripts were present in high abundance in leaves after herbivore egg laying, but transcripts involved in photosynthesis showed decreased abundance. Many pathogen-related genes and genes involved in phytohormone signaling were expressed, indicative of jasmonic acid biosynthesis and activation of jasmonic acid responsive genes. Cross-comparisons between different libraries based on expression profiles allowed the identification of genes with a potential relevance in egg-induced defenses, as well as other biological processes, including signal transduction

    Full Text Available Wittgenstein's Tractatus contains a mysterious aphorism to the effect that «ethics and aesthetics are the same». The existence of an underlying connivance between ethics and aesthetics has been acknowledged ever since ancient times. Here we try to look into this hard and interesting issue from the open horizon of boundary-philosophy, as put forward in my latest publications. The task will be carried out at three stages. The first one is given over to an elucidation of one core concept of ethics, freedom, in an interactive connection with our fore-understanding of our human condition. Then we raise the (Kantian question about how the ethical «symbolically resounds» through art. The third and last stage brings up the subject of the link between ethics and aesthetics on the ground of several examples, both ancient and modern (from the great tragedies and some artistic manifestations of our modernity.

    Un misterioso aforismo del Tractatus de Wittgenstein enuncia que «ética y estética son lo mismo». Que una corriente de complicidad existe entre ética y estética es reconocido desde la antigüedad. Lo ético se argumenta en la praxis; el arte lo hace a través de la poiésis, o creación, ya definida por Platón y Aristóteles. Aquí se intenta abordar esta interesante y difícil cuestión desde el horizonte abierto, a través de mis últimas publicaciones, por la filosofía del límite, y se realizará en tres etapas. Una primera dedicada a esclarecer uno de los conceptos nucleares de la ética, la libertad, en relación de interacción con la precomprensión que podemos poseer relativa a nuestra humana conditio. Se planteará luego la cuestión (kantiana de que a través del arte «resuena simbólicamente» lo ético.

    Full Text Available In its first part, this article dwells upon the pluralism and the complex nature of the documentary system in the Este dominion between the fifteenth and the sixteenth century: both are well shown by the structure of the princely archive and the control exerted on their archives by the governed communities. Nevertheless, what is afterwards underlined is the importance of institutional, documentary and administrative links; through them, territorialization and reciprocal legitimation practices took place among the varied political agents. Special stress is laid on the existence of ducal territorial chanceries, on their interaction with urban chanceries and on the creation of specular series of registers, with particular reference to the evolution of urban copialettere, where a shared elaboration of norms occurred between the fifteenth and the sixteenth century.

    Metasequoia glyptostroboides is an endangered relict conifer species endemic to China. In this study, expressed sequence tag-simple sequence repeat (EST-SSR) markers were developed using transcriptome mining for future genetic and functional studies. We collected 97,565 unigene sequences generated by 454 pyrosequencing. A bioinformatics analysis identified 2087 unique and putative microsatellites, from which 96 novel microsatellite markers were developed. Fifty-three of the 96 primer sets successfully amplified clear fragments of the expected sizes; 23 of those loci were polymorphic. The number of alleles per locus ranged from two to eight, with an average of three, and the observed and expected heterozygosity values ranged from 0 to 1.0 and 0.117 to 0.813, respectively. These microsatellite loci will enrich the genetic resources to develop functional studies and conservation strategies for this endangered relict species.

    Full Text Available Abstract Background The newt Notophthalmus viridescens possesses the remarkable ability to respond to cardiac damage by formation of new myocardial tissue. Surprisingly little is known about changes in gene activities that occur during the course of regeneration. To begin to decipher the molecular processes, that underlie restoration of functional cardiac tissue, we generated an EST database from regenerating newt hearts and compared the transcriptional profile of selected candidates with genes deregulated during zebrafish heart regeneration. Results A cDNA library of 100,000 cDNA clones was generated from newt hearts 14 days after ventricular injury. Sequencing of 11520 cDNA clones resulted in 2894 assembled contigs. BLAST searches revealed 1695 sequences with potential homology to sequences from the NCBI database. BLAST searches to TrEMBL and Swiss-Prot databases assigned 1116 proteins to Gene Ontology terms. We also identified a relatively large set of 174 ORFs, which are likely to be unique for urodele amphibians. Expression analysis of newt-zebrafish homologues confirmed the deregulation of selected genes during heart regeneration. Sequences, BLAST results and GO annotations were visualized in a relational web based database followed by grouping of identified proteins into clusters of GO Terms. Comparison of data from regenerating zebrafish hearts identified biological processes, which were uniformly overrepresented during cardiac regeneration in newt and zebrafish. Conclusion We concluded that heart regeneration in newts and zebrafish led to the activation of similar sets of genes, which suggests that heart regeneration in both species might follow similar principles. The design of the newly established newt EST database allows identification of molecular pathways important for heart regeneration.

    Full Text Available Lignins are phenolic polymers found in the secondary wall of plant conductive systems where they play an important role by reducing the permeability of the cell wall to water. Lignins are also responsible for the rigidity of the cell wall and are involved in mechanisms of resistance to pathogens. The metabolic routes and enzymes involved in synthesis of lignins have been largely characterized and representative genes that encode enzymes involved in these processes have been cloned from several plant species. The synthesis of lignins is liked to the general metabolism of the phenylpropanoids in plants, having enzymes (e.g. phenylalanine ammonia-lyase (PAL, cinnamate 4-hydroxylase (C4H and caffeic acid O-methyltransferase (COMT common to other processes as well as specific enzymes such as cinnamoyl-CoA reductase (CCR and cinnamyl alcohol dehydrogenase (CAD. Some maize and sorghum mutants, shown to have defective in CAD and/or COMT activity, are easier to digest because they have a reduced lignin content, something which has motivated different research groups to alter the lignin content and composition of model plants by genetic engineering try to improve, for example, the efficiency of paper pulping and digestibility. In the work reported in this paper, we have made an inventory of the sugarcane expressed sequence tag (EST coding for enzymes involved in lignin metabolism which are present in the sugarcane EST genome project (SUCEST database. Our analysis focused on the key enzymes ferulate-5-hydroxylase (F5H, caffeic acid O-methyltransferase (COMT, caffeoyl CoA O-methyltransferase (CCoAOMT, hydroxycinnamate CoA ligase (4CL, cinnamoyl-CoA reductase (CCR and cinnamyl alcohol dehydrogenase (CAD. The comparative analysis of these genes with those described in other species could be used as molecular markers for breeding as well as for the manipulation of lignin metabolism in sugarcane.

    Beaches are social-ecological systems that provide several services improving human well-being. However, as one of the major coastal interfaces they are subject to plastic pollution, one of the most significant global environmental threats at present. For the first time for Uruguayan beaches, this study assessed and quantified the accumulation of plastic and microplastic debris on sandy beaches of the major touristic destination Punta del Este during the austral spring of 2013. Aiming to provide valuable information for decision-making, we performed a detailed analysis of plastic debris, their eventual transport pathways to the coast (from land and sea), and the associated persistent pollutants. The results indicated that the smallest size fractions (<20 mm) were the dominant size range, with fragments and resin pellets as types with the highest number of items. PAHs and PCBs were found in plastic debris, and their levels did not differ from baseline values reported for similar locations. The abundance of plastic debris was significantly and positively correlated with both the presence of possible land-based sources (e.g. storm-water drains, beach bars, beach access, car parking, and roads), and dissipative beach conditions. The analysis of coastal currents suggested some potential deposition areas along Punta del Este, and particularly for resin pellets, although modeling was not conclusive. From a local management point of view, the development and use of indices that allow predicting trends in the accumulation of plastic debris would be critically useful. The time dimension (e.g. seasonal) should also be considered for this threat, being crucial for locations such as Uruguay, where the use of beaches increases significantly during the summer. This first diagnosis aims to generate scientific baseline, necessary for improved management of plastic litter on beaches and their watersheds. Copyright © 2016 Elsevier Ltd. All rights reserved.

Se trata de una vida anulada por una especie de testamento de género por parte del patriarca ausente / presente. In 1982, Josefina Vicens published her second novel entitled The False Years. This article discusses the issue of Mexican patriarchy in family structures where power, violence, infidelity, corruption, machismo and the subordination of women with regard to the authority of the patriarch form the basis of an incisive discourse in which Vicens observes gender relations within the traditional Mexican family. The identity of the novel’s protagonist is discussed throughout the narrative, as is his ambivalence with respect to the construction of his gender, a feeling relegated to the margins of his wishes and possible acheivements. It is the portrait of a life nullified by a sort of testament of gender handed down by the absent/present figure of the patriarch.

Au fait le génome de deux personnes ne diffère que par 0.1% des 3.2 milliards de paires de bases, ce qui implique les effets indésirables des médicaments, qui ont un très important impact sur le plan clinique que sur le plan économique. Or cette dernière décennie ces effets indésirables ont pu être évités grâce aux tests pharmacogénétiques. Au Maroc, la recherche en pharmacogénétique commence à susciter l'intérêt des chercheurs avec quelques études.

    The genetic diversity and relationship of 42 tomato varieties sourced from different geographic regions was examined with EST-SSR markers. The genetic diversity was between 0.18 and 0.77, with a mean of 0.49; the polymorphic information content ranged from 0.17 to 0.74, with a mean of 0.45. This indicates a fairly high degree of diversity among these tomato varieties. Based on the cluster analysis using unweighted pair-group method with arithmetic average (UPGMA), all the tomato varieties fell into 5 groups, with no obvious geographical distribution characteristics despite their diverse sources. The principal component analysis (PCA) supported the clustering result; however, relationships among varieties were more complex in the PCA scatterplot than in the UPGMA dendrogram. This information about the genetic relationships between these tomato lines helps distinguish these 42 varieties and will be useful for tomato variety breeding and selection. We confirm that the EST-SSR marker system is useful for studying genetic diversity among tomato varieties. The high degree of polymorphism and the large number of bands obtained per assay shows that SSR is the most informative marker system for tomato genotyping for purposes of rights/protection and for the tomato industry in general. It is recommended that these varieties be subjected to identification using an SSR-based manual cultivar identification diagram strategy or other easy-to-use and referable methods so as to provide a complete set of information concerning genetic relationships and a readily usable means of identifying these varieties.

    Pacific white shrimp has become a major aquaculture and fishery species worldwide. Although a large scale EST resource has been publicly available since 2008, the data have not yet been widely used for SNP discovery or transcriptome-wide assessment of selective pressure. In this study, a set of 155 411 expressed sequence tags (ESTs) from the NCBI database were computationally analyzed and 17 225 single nucleotide polymorphisms (SNPs) were predicted, including 9 546 transitions, 5 124 transversions and 2 481 indels. Among the 7 298 SNP substitutions located in functionally annotated contigs, 58.4% (4 262) are non-synonymous SNPs capable of introducing amino acid mutations. Two hundred and fifty nonsynonymous SNPs in genes associated with economic traits have been identified as candidates for markers in selective breeding. Diversity estimates among the synonymous nucleotides were on average 3.49 times greater than those in non-synonymous, suggesting negative selection. Distribution of non-synonymous to synonymous substitutions (Ka/Ks) ratio ranges from 0 to 4.01, (average 0.42, median 0.26), suggesting that the majority of the affected genes are under purifying selection. Enrichment analysis identified multiple gene ontology categories under positive or negative selection. Categories involved in innate immune response and male gamete generation are rich in positively selected genes, which is similar to reports in Drosophila and primates. This work is the first transcriptome-wide assessment of selective pressure in a Penaeid shrimp species. The functionally annotated SNPs provide a valuable resource of potential molecular markers for selective breeding.

    Cork oak (Quercus suber) is one of the rare trees with the ability to produce cork, a material widely used to make wine bottle stoppers, flooring and insulation materials, among many other uses. The molecular mechanisms of cork formation are still poorly understood, in great part due to the difficulty in studying a species with a long life-cycle and for which there is scarce molecular/genomic information. Cork oak forests are of great ecological importance and represent a major economic and social resource in Southern Europe and Northern Africa. However, global warming is threatening the cork oak forests by imposing thermal, hydric and many types of novel biotic stresses. Despite the economic and social value of the Q. suber species, few genomic resources have been developed, useful for biotechnological applications and improved forest management. We generated in excess of 7 million sequence reads, by pyrosequencing 21 normalized cDNA libraries derived from multiple Q. suber tissues and organs, developmental stages and physiological conditions. We deployed a stringent sequence processing and assembly pipeline that resulted in the identification of ~159,000 unigenes. These were annotated according to their similarity to known plant genes, to known Interpro domains, GO classes and E.C. numbers. The phylogenetic extent of this ESTs set was investigated, and we found that cork oak revealed a significant new gene space that is not covered by other model species or EST sequencing projects. The raw data, as well as the full annotated assembly, are now available to the community in a dedicated web portal at http://www.corkoakdb.org. This genomic resource represents the first trancriptome study in a cork producing species. It can be explored to develop new tools and approaches to understand stress responses and developmental processes in forest trees, as well as the molecular cascades underlying cork differentiation and disease response.

    Full Text Available Little information is available on gene expression profiling of halophyte A. canescens. To elucidate the molecular mechanism for stress tolerance in A. canescens, a full-length complementary DNA library was generated from A. canescens exposed to 400 mM NaCl, and provided 343 high-quality ESTs. In an evaluation of 343 valid EST sequences in the cDNA library, 197 unigenes were assembled, among which 190 unigenes (83.1% ESTs were identified according to their significant similarities with proteins of known functions. All the 343 EST sequences have been deposited in the dbEST GenBank under accession numbers JZ535802 to JZ536144. According to Arabidopsis MIPS functional category and GO classifications, we identified 193 unigenes of the 311 annotations EST, representing 72 non-redundant unigenes sharing similarities with genes related to the defense response. The sets of ESTs obtained provide a rich genetic resource and 17 up-regulated genes related to salt stress resistance were identified by qRT-PCR. Six of these genes may contribute crucially to earlier and later stage salt stress resistance. Additionally, among the 343 unigenes sequences, 22 simple sequence repeats (SSRs were also identified contributing to the study of A. canescens resources.

    Full Text Available In this study, a collection of 24,840 expressed sequence tags (ESTs generated from five mango (Mangifera indica L. cDNA libraries was mined for EST-based simple sequence repeat (SSR markers. Over 1,000 ESTs with SSR motifs were detected from more than 24,000 EST sequences with di- and tri-nucleotide repeat motifs the most abundant. Of these, 25 EST-SSRs in genes involved in plant development, stress response, and fruit color and flavor development pathways were selected, developed into PCR markers and characterized in a population of 32 mango selections including M. indica varieties, and related Mangifera species. Twenty-four of the 25 EST-SSR markers exhibited polymorphisms, identifying a total of 86 alleles with an average of 5.38 alleles per locus, and distinguished between all Mangifera selections. Private alleles were identified for Mangifera species. These newly developed EST-SSR markers enhance the current 11 SSR mango genetic identity panel utilized by the Australian Mango Breeding Program. The current panel has been used to identify progeny and parents for selection and the application of this extended panel will further improve and help to design mango hybridization strategies for increased breeding efficiency.

    The brown planthopper (BPH), Nilaparvata lugens (Hemiptera, Delphacidae), is a serious insect pests of rice plants. Major means of BPH control are application of agricultural chemicals and cultivation of BPH resistant rice varieties. Nevertheless, BPH strains that are resistant to agricultural chemicals have developed, and BPH strains have appeared that are virulent against the resistant rice varieties. Expressed sequence tag (EST) analysis and related applications are useful to elucidate the mechanisms of resistance and virulence and to reveal physiological aspects of this non-model insect, with its poorly understood genetic background. More than 37,000 high-quality ESTs, excluding sequences of mitochondrial genome, microbial genomes, and rDNA, have been produced from 18 libraries of various BPH tissues and stages. About 10,200 clusters have been made from whole EST sequences, with average EST size of 627 bp. Among the top ten most abundantly expressed genes, three are unique and show no homology in BLAST searches. The actin gene was highly expressed in BPH, especially in the thorax. Tissue-specifically expressed genes were extracted based on the expression frequency among the libraries. An EST database is available at our web site. The EST library will provide useful information for transcriptional analyses, proteomic analyses, and gene functional analyses of BPH. Moreover, specific genes for hemimetabolous insects will be identified. The microarray fabricated based on the EST information will be useful for finding genes related to agricultural and biological problems related to this pest.

    Full length open reading frame of pyrethroid detoxification gene, Est3385, contains 963 nucleotides. This gene was identified and cloned based on the genome sequence of Rhodopseudomonas palustris PSB-S available at the GneBank. The predicted amino acid sequence of Est3385 shared moderate identities (30-46%) with the known homologous esterases. Phylogenetic analysis revealed that Est3385 was a member in the esterase family I. Recombinant Est3385 was heterologous expressed in E. coli, purified and characterized for its substrate specificity, kinetics and stability under various conditions. The optimal temperature and pH for Est3385 were 35 °C and 6.0, respectively. This enzyme could detoxify various pyrethroid pesticides and degrade the optimal substrate fenpropathrin with a Km and Vmax value of 0.734 ± 0.013 mmol·l -1 and 0.918 ± 0.025 U·µg -1 , respectively. No cofactor was found to affect Est3385 activity but substantial reduction of enzymatic activity was observed when metal ions were applied. Taken together, a new pyrethroid degradation esterase was identified and characterized. Modification of Est3385 with protein engineering toolsets should enhance its potential for field application to reduce the pesticide residue from agroecosystems.

    Full Text Available El 15M funcionó en un régimen estético inédito, con una protesta eminentemente visual, de una multitud creativa. Dentro de una política del simulacro, entendiendo la protesta como acto político, ético y estético, el movimiento actuó como fábrica de identidades y políticas emancipatoria, convirtiendo el elemento estético en principal herramienta de protesta y de acción; primando la formalidad, obrando desde lo cognitivo, desde la subjetivación de lo estético. Toda emancipación social pasaba por una ruptura estética, reapropiando el espacio público desde inéditas prácticas subjetivadoras, ordenando toda realidad conocible y visible en un nuevo paisaje político y estético. Como una democracia performativa, a través de la protesta se revisaron condiciones normativas de vida, rompiendo normas preestablecidas y explorando formas inéditas o ficticias; siguiendo cierta estética de la existencia, una renovación sustancial de formatos, sentidos, significados y de mitos.

    Full Text Available Este artículo se centra en el ocio estético valioso en Aristóteles, partiendo del análisis de la Poética y, específicamente, de la comprensión de la experiencia estética como actividad mental. Se destaca su dimensión ética, realzando su valor en el desarrollo del ser humano, así como el de la propia obra de arte, en la medida en que el poeta ha sabido construirla, encarnando en la trama los hechos y universalizándolos, al modo que le es propio. Aristóteles se refiere a la tragedia, pero por extensión esta valoración proporciona una pauta de lectura de la experiencia de ocio estético. El marco autónomo para el ámbito estético, que inaugura Aristóteles, y su valoración vinculada a la dimensión ética, a la comprensión intelectual y al placer estético proporcionan la base para sostener que el ocio estético se confirma como un horizonte enmarcado en la senda de lo valioso y adecuado para realizar la vida que le es propia al ser humano.

    Twenty-five primer pairs developed from genomic simple sequence repeats (SSR) were compared with 25 expressed sequence tags (EST) SSRs to evaluate the efficiency of these two sets of primers using 59 sugarcane genetic stocks. The mean polymorphism information content (PIC) of genomic SSR was higher (0.72) compared to the PIC value recorded by EST-SSR marker (0.62). The relatively low level of polymorphism in EST-SSR markers may be due to the location of these markers in more conserved and expressed sequences compared to genomic sequences which are spread throughout the genome. Dendrogram based on the genomic SSR and EST-SSR marker data showed differences in grouping of genotypes. A total of 59 sugarcane accessions were grouped into 6 and 4 clusters using genomic SSR and EST-SSR, respectively. The highly efficient genomic SSR could subcluster the genotypes of some of the clusters formed by EST-SSR markers. The difference in dendrogram observed was probably due to the variation in number of markers produced by genomic SSR and EST-SSR and different portion of genome amplified by both the markers. The combined dendrogram (genomic SSR and EST-SSR) more clearly showed the genetic relationship among the sugarcane genotypes by forming four clusters. The mean genetic similarity (GS) value obtained using EST-SSR among 59 sugarcane accessions was 0.70, whereas the mean GS obtained using genomic SSR was 0.63. Although relatively lower level of polymorphism was displayed by the EST-SSR markers, genetic diversity shown by the EST-SSR was found to be promising as they were functional marker. High level of PIC and low genetic similarity values of genomic SSR may be more useful in DNA fingerprinting, selection of true hybrids, identification of variety specific markers and genetic diversity analysis. Identification of diverse parents based on cluster analysis can be effectively done with EST-SSR as the genetic similarity estimates are based on functional attributes related to

    Como os alunos de hotelaria avaliam os processos de treinamento e desenvolvimento dirigidos a si mesmos enquanto estagiários e na comparação com os processos direcionados aos funcionários das organizações hoteleiras?  Para dar conta deste problema, lançou-se mão de referencial teórico dos campos da administração e da hotelaria. Metodologicamente, optou-se pela técnica qualitativa da análise de conteúdo de entrevistas semi-estruturadas, dentro das seguintes categorias: eventual experiência profissional anterior ao estágio; amplitude da função do estagiário de hotelaria dentro do hotel; programas de treinamento nos hotéis (para os funcionários; para os estagiários; tipologia de treinamentos aplicáveis ao estágio; interesse do aluno-estagiário pelo estágio. Os resultados mostraram que há evidências de um mal estar dos alunos com relação à atividade. De início, extremamente motivados, ansiosos por conhecer e desenvolver uma prática profissional, que se promete agradável, marcada pelo contato com os clientes e cheia de surpresas e de acontecimentos agradáveis, não raro alguns se frustram. No mais das vezes, tratados como mão de obra barata, submetidos a tarefas subalternas para as quais são designados nunca por suas qualidades técnicas, o desgaste e a decepção são naturais.

Os principais fatores de risco evidenciados a partir de estudos epidemiológicos em várias populações do mundo e associados a essa neoplasia são alguns padrões de dieta. Com a descoberta do papel carcinogênico das nitrosaminas e do potencial anti-oxidante da vitamina C, algumas das associações entre câncer gástrico e padrões de dieta passaram a ser parcialmente entendidas. Com a descrição da Helicobacter pylori em 1983 e as evidências da relação dessa bactéria com certos processos patológicos do estômago, alguns precursores do câncer gástrico, novos elementos foram agregados ao processo fisiopatológico dessa entidade.

The main risk factors for this neoplasm are certain diet patterns that became evident through epidemiological studies in various population groups. After the carcinogenic effects of nitrosamines and the anti-oxidant activity of vitamin C were discovered, some of the associations between stomach cancer and diet were partially understood. After the description of Helicobacter pylori in 1983 and the evidence of the relationship between this bacteria and certain stomach diseases, new elements were added to the knowledge about the development of this neoplasm. Current knowledge, albeit incomplete, provides interesting prospects for the prevention and early diagnosis of stomach cancer.

  14. Geologic Map of the Estes Park 30' x 60' Quadrangle, North-Central Colorado

    Cole, James C.; Braddock, William A.

    2009-01-01

    The rocks and landforms of the Estes Park 30 x 60 minute quadrangle display an exceptionally complete record of geologic history in the northern Front Range of Colorado. The Proterozoic basement rocks exposed in the core of the range preserve evidence of Paleoproterozoic marine sedimentation, volcanism, and regional soft-sediment deformation, followed by regional folding and gradational metamorphism. The metasedimentary rocks of the Estes Park quadrangle are distinct within northern Colorado for preserving the complete metamorphic zonation from low-grade chlorite-muscovite phyllites, through middle greenschist-grade rocks with sequential aluminous porphyroblasts, to partially melted gneisses that contain high-grade cordierite and garnet in the non-melted residues. Regional and textural evidence shows that the widespread metamorphism was essentially concurrent with intrusion of the Boulder Creek Granodiorite and related magmas and with the peak of deformation in the partially melted high-grade rocks. The metamorphic thermal pulse arrived later following the peak of deformation in the physically higher, cooler, low-grade terrane. Mesoproterozoic time was marked by intrusion of biotite granite in the Longs Peak-St Vrain batholith, a complex, irregular body that occupies nearly half of the core of the Front Range in this quadrangle. The magma was dry and viscous as it invaded the metamorphic rocks and caused wholesale plastic folding of the wall rock structure. Steep metamorphic foliation that resulted from the Paleoproterozoic deformations was bowed upward and re-oriented into flat-lying attitudes as the crystal-rich magma rose buoyantly and spread out in the middle crust. Magma invaded the schists and gneisses along weak foliation planes and produced a characteristic sill-upon-sill intrusive fabric, particularly in the higher parts of the batholith. Broad, open arches and swales that are defined by the flow-aligned feldspar foliation of the granite, as well as by

    The cupuassu tree (Theobroma grandiflorum) (Willd. ex Spreng.) Schum. is a fruitful species from the Amazon with great economical potential, due to the multiple uses of its fruit´s pulp and seeds in the food and cosmetic industries, including the production of cupulate, an alternative to chocolate. In order to support the cupuassu breeding program and to select plants presenting both pulp/seed quality and fungal disease resistance, SSRs from Next Generation Sequencing ESTs were obtained and used in diversity analysis. From 8,330 ESTs, 1,517 contained one or more SSRs (1,899 SSRs identified). The most abundant motifs identified in the EST-SSRs were hepta- and trinucleotides, and they were found with a minimum and maximum of 2 and 19 repeats, respectively. From the 1,517 ESTs containing SSRs, 70 ESTs were selected based on their functional annotation, focusing on pulp and seed quality, as well as resistance to pathogens. The 70 ESTs selected contained 77 SSRs, and among which, 11 were polymorphic in cupuassu genotypes. These EST-SSRs were able to discriminate the cupuassu genotype in relation to resistance/susceptibility to witches' broom disease, as well as to pulp quality (SST/ATT values). Finally, we showed that these markers were transferable to cacao genotypes, and that genome availability might be used as a predictive tool for polymorphism detection and primer design useful for both Theobroma species. To our knowledge, this is the first report involving EST-SSRs from cupuassu and is also a pioneer in the analysis of marker transferability from cupuassu to cacao. Moreover, these markers might contribute to develop or saturate the cupuassu and cacao genetic maps, respectively.

    Zingiber officinale is a model spice herb, well known for its medicinal value. It is primarily a vegetatively propagated commercial crop. However, considerable diversity in its morphology, fiber content and chemoprofiles has been reported. The present study explores the utility of EST-derived markers in studying genetic diversity in different accessions of Z. officinale and their cross transferability within the Zingiberaceae family. A total of 38,115 ESTs sequences were assembled to generate 7850 contigs and 10,762 singletons. SSRs were searched in the unigenes and 515 SSR-containing ESTs were identified with a frequency of 1 SSR per 25.21 kb of the genome. These ESTs were also annotated using BLAST2GO. Primers were designed for 349 EST-SSRs and 25 primer pairs were randomly picked for EST SSR study. Out of these, 16 primer pairs could be optimized for amplification in different accessions of Z. officinale as well as other species belonging to Zingiberaceae. GES454, GES466, GES480 and GES486 markers were found to exhibit 100% cross-transferability among different members of Zingiberaceae.

    Full Text Available Kivircik sheep is an important local Turkish sheep according to its meat quality and milk productivity. The aim of this study was to analyze gene expression profiles of both prenatal and postnatal stages for the Kivircik sheep. Therefore, two different cDNA libraries, which were taken from the same Kivircik sheep mammary gland tissue at prenatal and postnatal stages, were constructed. Total 3072 colonies which were randomly selected from the two libraries were sequenced for developing a sheep ESTs collection. We used Phred/Phrap computer programs for analysis of the raw EST and readable EST sequences were assembled with the CAP3 software. Putative functions of all unique sequences and statistical analysis were determined by Geneious software. Total 422 ESTs have over 80% similarity to known sequences of other organisms in NCBI classified by Panther database for the Gene Ontology (GO category. By comparing gene expression profiles, we observed some putative genes that may be relative to reproductive performance or play important roles in milk synthesis and secretion. A total of 2414 ESTs have been deposited to the NCBI GenBank database (GW996847–GW999260. EST data in this study have provided a new source of information to functional genome studies of sheep.

    Testing for embryotoxicity in vitro is an attractive alternative to animal experimentation. The embryonic stem cell test (EST) is such a method, and it has been formally validated by the European Centre for the Validation of Alternative Methods. A number of recent studies have underscored the potential of this method. However, the EST performed well below the 78% accuracy expected from the validation study using a new set of chemicals and pharmaceutical compounds, and also of toxicity criteria, tested to enlarge the database of the validated EST as part of the Work Package III of the ReProTect Project funded within the 6th Framework Programme of the European Union. To assess the performance and applicability domain of the EST we present a detailed review of the substances and their effects in the EST being nitrofen, ochratoxin A, D-penicillamine, methylazoxymethanol, lovastatin, papaverine, warfarin, β-aminopropionitrile, dinoseb, furosemide, doxylamine, pravastatin, and metoclopramide. By delineation of the molecular mechanisms of the substances we identify six categories of reasons for misclassifications. Some of these limitations might also affect other in vitro methods assessing embryotoxicity. Substances that fall into these categories need to be included in future validation sets and in validation guidelines for embryotoxicity testing. Most importantly, we suggest conceivable improvements and additions to the EST which will resolve most of the limitations.

  3. Construction of 12 EST libraries and characterization of a 12,226 EST dataset for chicory (Cichorium intybus root, leaves and nodules in the context of carbohydrate metabolism investigation

    Full Text Available Abstract Background The industrial chicory, Cichorium intybus, is a member of the Asteraceae family that accumulates fructan of the inulin type in its root. Inulin is a low calories sweetener, a texture agent and a health promoting ingredient due to its prebiotic properties. Average inulin chain length is a critical parameter that is genotype and temperature dependent. In the context of the study of carbohydrate metabolism and to get insight into the transcriptome of chicory root and to visualize temporal changes of gene expression during the growing season, we obtained and characterized 10 cDNA libraries from chicory roots regularly sampled in field during a growing season. A leaf and a nodule libraries were also obtained for comparison. Results Approximately 1,000 Expressed Sequence Tags (EST were obtained from each of twelve cDNA libraries resulting in a 12,226 EST dataset. Clustering of these ESTs returned 1,922 contigs and 4,869 singlets for a total of 6,791 putative unigenes. All ESTs were compared to public sequence databases and functionally classified. Data were specifically searched for sequences related to carbohydrate metabolism. Season wide evolution of functional classes was evaluated by comparing libraries at the level of functional categories and unigenes distribution. Conclusion This chicory EST dataset provides a season wide outlook of the genes expressed in the root and to a minor extent in leaves and nodules. The dataset contains more than 200 sequences related to carbohydrate metabolism and 3,500 new ESTs when compared to other recently released chicory EST datasets, probably because of the season wide coverage of the root samples. We believe that these sequences will contribute to accelerate research and breeding of the industrial chicory as well as of closely related species.

    Integral field spectroscopy (IFS) is a technique that allows one to obtain the spectra of all the points of a bidimensional field of view simultaneously. It is being applied to the new generation of the largest night-time telescopes but it is also an innovative technique for solar physics. This paper presents the design of a new image slicer, MuSICa (Multi-Slit Image slicer based on collimator-Camera), for the integral field spectrograph of the 4-m aperture European Solar Telescope (EST). MuSICa is a multi-slit image slicer that decomposes an 80 arcsec2 field of view into slices of 50 μm and reorganizes it into eight slits of 0.05 arcsec width × 200 arcsec length. It is a telecentric system with an optical quality at diffraction limit compatible with the two modes of operation of the spectrograph: spectroscopic and spectro-polarimetric. This paper shows the requirements, technical characteristics and layout of MuSICa, as well as other studied design options.

Así, el lenguaje es la condición de la cultura que contribuye a crearla y permite que se pueda establecer una comunicación entre todos los hombres. De esta manera, lo mismo que una lengua se aprende en una comunidad lingüística, la lectura de las imágenes se aprende en el contexto de una cultura. Hay una relación de intercambio recíproco entre el lenguaje literario y el lenguaje artístico con la cultura. Y a su vez, el arte es quizá el modo más sublime de expresar los sentimientos, por lo cual el lenguaje del arte es un diálogo y una comunicación directa y profunda entre todos, aunque se hablen diferentes lenguas.

    Full Text Available Esculturas e monumentos públicos tradicionalmente foram construídos e pensados segundo a lógica do poder vigente, para difusão e fixação de seus pontos de vista. A partir do período entre guerras, o cenário político brasileiro discute as propostas iconográficas dos partidos nazifascistas e comunistas europeus, até o fim do regime Vargas, em uma política de afirmação de símbolos concretos de nacionalidade e poder. O escopo deste artigo é discutir essas heranças autoritárias por meio do estudo de monumentos encontrados em praças públicas de Curitiba, assim como entender como as idéias e o ambiente político da época informaram suas soluções visuais. O estudo da recepção das imagens ajuda-nos a entender as relações entre a população e o status quo, e as suas lutas internas, muitas vezes encobertas por debates aparentemente "apenas" estéticos.

The target of this text is to explain in which way some humoristic interventions could help in the treatment of psychotic patients, pacifying the incidence of the "pulsional" and making the person, whose existence is not limited by the phallus, to start using speech. With this aim, our starting point was the mentioning of a "wit", or joke, the humoristic effect, which is Freudian by excellence. The hypothesis that we foresee is that the economic mishaps related to the wit, even on their preliminary stages, could clarify if and how such interventions could be effective in a possible treatment of psychosis.

    Full Text Available CitEST project resulted in the construction of cDNA libraries from different Citrus sp. tissues under various physiological conditions. Among them, plantlets of Rangpur lime were exposed to hydroponic conditions with and without water stress using PEG6000. RNA from roots was obtained and generated a total of 4,130 valid cDNA reads, with 2,020 from the non-stressed condition and 2,110 from the stressed set. Bioinformatic analyses measured the frequency of each read in the libraries and yielded an in silico transcriptional profile for each condition. A total of 40 contigs were differentially expressed and allowed to detect up-regulated homologue sequences to well known genes involved in stress response, such as aquaporins, dehydrin, sucrose synthase, and proline-related synthase. Some sequences could not be classified by using FunCat and remained with an unknown function. A large number of sequences presented high similarities to annotated genes involved with cell energy, protein synthesis and cellular transport, suggesting that Rangpur lime may sustain active cell growth under stressed condition. The presence of membrane transporters and cell signaling components could be an indication of a coordinated morphological adaptation and biochemical response during drought, helping to explain the higher tolerance of this rootstock to water stress.

    Full Text Available To identify fast-evolving genes in reef-building corals, we performed direct comparative sequence analysis with expressed sequence tag (EST datasets from two acroporid species: Acropora palmata from the Caribbean Sea and A. millepora from the Great Barrier Reef in Australia. Comparison of 589 independent sequences from 1,421 A. palmata contigs, with 10,247 A. millepora contigs resulted in the identification of 196 putative homologues. Most of the homologous pairs demonstrated high amino acid similarities (over 90%. Comparisons of putative homologues showing low amino acid similarities (under 90% among the Acropora species to the near complete datasets from two other cnidarians (Hydra magnipapillata and Nematostella vectensis implied that some were non-orthologous. Within 86 homologous pairs, 39 exhibited dN/dS ratios significantly less than 1, suggesting that these genes are under purifying selection associated with functional constraints. Eight independent genes showed dN/dS ratios exceeding 1, while three deviated significantly from 1, suggesting that these genes may play important roles in the adaptive evolution of Acropora. Our results also indicated that CEL-III lectin was under positive selection, consistent with a possible role in immunity or symbiont recognition. Further studies are needed to clarify the possible functions of the genes under positive selection to provide insight into the evolutionary process of corals.

Desde el concepto mismo se plantea una renovación constante que ha ido posibilitando su maduración. Esto también ha influido en las formas de medición donde se ha caído en un buen número de normas, guías y metodologías que han aportado a la comprensión de la RSE pero también vienen significando la confusión frente a cuales deben ser los parámetros básicos de operación. Este artículo en la primera parte hace un recorrido por los conceptos; en la segunda sección se aproxima a las normas y guías; y en la tercera, concluye planteando la necesidad de generar consensos frente a las normas y auditorías de tal manera que la RSE sea regulada en sus mínimos deseables por parte de las sociedades

    Full Text Available Polyporus umbellatus is one of the most widely used and precious medicinal fungi and the underground sclerotia are known to be with great medicinal value. However, the molecular mechanisms involved in sclerotial development are poorly understood. In the present study, we constructed a forward suppression subtractive hybridization (SSH cDNA library of Polyporus umbellatus to identify genes expressing differently between mycelium and sclerotia. In this library, a total of 1202 clones were sequenced, assembled into 222 contigs and 524 singletons which were further searched against the NCBI nonredundant (NR protein database (E-value cutoff, 10−5. Based on sequence similarity with known proteins, 378 sequences between mycelium and sclerotial were identified and classified into different functional categories through Gene Ontology (GO, Clusters of orthologous Groups of proteins (COGs. We have finally identified a majority of differentially expressed genes (constituting 5.6% of the present library between the two different periods. An expression level of 32 selected expressed sequence tags (ESTs generated from the above SSH cDNA library was studied through RT-PCR. This study provides the first global overview of genes putatively involved in Polyporus umbellatus sclerotial development and provides a preliminary basis for further functional research in terms of regulated gene expression in sclerotial production.

    2007-06-01

    Full Text Available Abstract Background The eastern oyster, Crassostrea virginica (Gmelin 1791, is an economically important species cultured in many areas in North America. It is also ecologically important because of the impact of its filter feeding behaviour on water quality. Populations of C. virginica have been threatened by overfishing, habitat degradation, and diseases. Through genome research, strategies are being developed to reverse its population decline. However, large-scale expressed sequence tag (EST resources have been lacking for this species. Efficient generation of EST resources from this species has been hindered by a high redundancy of transcripts. The objectives of this study were to construct a normalized cDNA library for efficient EST analysis, to generate thousands of ESTs, and to analyze the ESTs for microsatellites and potential single nucleotide polymorphisms (SNPs. Results A normalized and subtracted C. virginica cDNA library was constructed from pooled RNA isolated from hemocytes, mantle, gill, gonad and digestive tract, muscle, and a whole juvenile oyster. A total of 6,528 clones were sequenced from this library generating 5,542 high-quality EST sequences. Cluster analysis indicated the presence of 635 contigs and 4,053 singletons, generating a total of 4,688 unique sequences. About 46% (2,174 of the unique ESTs had significant hits (E-value ≤ 1e-05 to the non-redundant protein database; 1,104 of which were annotated using Gene Ontology (GO terms. A total of 35 microsatellites were identified from the ESTs, with 18 having sufficient flanking sequences for primer design. A total of 6,533 putative SNPs were also identified using all existing and the newly generated EST resources of the eastern oysters. Conclusion A high quality normalized cDNA library was constructed. A total of 5,542 ESTs were generated representing 4,688 unique sequences. Putative microsatellite and SNP markers were identified. These genome resources provide the

    Full Text Available «Le fascisme, c’est du théâtre», sostiene Jean Genet, e come tale i suoi legami con la natura e la prassi della messa in scena sono essenziali alla specificità del fenomeno. La resa spettacolare della nazionalizzazione delle masse è stata senz’altro tra i temi fondamentali della ricerca sui totalitarismi. Il mio proposito è qui quello di intarsiare alcuni nuclei consolidati della ricerca storica con le rese squisitamente letterarie di quello che fu poco più che un  decennio di immensi tableaux vivants, visioni di un nuovo ordine di massa. Un’opera d’arte collettiva, basata su una premessa  fondamentale: dare “figurabilità” ai detriti e alle rovine (rimosse? di alcuni miti delle origini propri della cultura romantica, e  consapevolmente avviare e mettere in luce un enorme processo più generale di disgregazione del logos e di tutta la civiltà europea nella sua prospettiva diremo cartesiana, geometrica e razionalista. Il mio discorso si fonda, anche se in breve, su un testo solo: la Gerbe des forces (1937 di A. de Châteaubriant, uno dei più singolari resoconti di pellegrinaggio politico verso il miraggio totalitario che si sia dato tre le due guerre mondiali. Soccorsi non secondari sono il saggio di Sontag Under the sign of Saturn (1980 e quello di Tame La Mystique du Fascisme dans l’oeuvre de Robert Brasillach (1986. According to Jean Genet: «Le fascisme, c’est du théâtre», and as such its relationship with the nature and praxis of staging are essential to the specificity of the phenomenon. The magnificent representation of mass nationalisation is beyond doubt one of the fundamental issues when investigating totalitarianisms.

    We report first-year survival rates of 49 captive-reared Hispaniolan Parrots (Amazona ventralis) released in Parque Nacional del Este, Dominican Republic. Our goal was to learn about factors affecting postrelease survival. Specifically, we tested if survival was related to movements and whether modifying prerelease protocols influenced survival rates. We also estimated survival in the aftermath of Hurricane Georges (22 September 1998). Twenty-four parrots, fitted with radio-transmitters, were released between 14 September and 12 December 1997. Twenty-five more were released between 29 June and 16 September 1998. First-year survival rates were 30% in 1997 and 29% in 1998. Survival probability was related to bird mobility. In contrast to birds released in 1997, none of the 25 parrots released in 1998 suffered early postrelease mortality (i.e., 3-5 days after release). Two adjustments to prerelease protocols (increased exercise and reduced blood sampling) made in 1998 may have contributed to differences in mobility and survival between years. The reduction of early postrelease mortality in 1998 was encouraging, as was the prospect for higher first-year survival (e.g., 30% to 65%). Only one death was attributed to the immediate impact of the hurricane. Loss of foraging resources was likely a major contributor to ensuing mortality. Birds increased their mobility, presumably in search of food. Survival rates dropped 23% in only eight weeks posthurricane. This study underscores the value of standardized prerelease protocols, and of estimating survival and testing for factors that might influence it. Inferences from such tests will provide the best basis to make adjustments to a release program.

    Dendrobiumofficinale (Orchidaceae) is one of the world's most endangered plants with great medicinal value. In nature, D. officinale seeds must establish symbiotic relationships with fungi to germinate. However, the molecular events involved in the interaction between fungus and plant during this process are poorly understood. To isolate the genes involved in symbiotic germination, a suppression subtractive hybridization (SSH) cDNA library of symbiotically germinated D. officinale seeds was constructed. From this library, 1437 expressed sequence tags (ESTs) were clustered to 1074 Unigenes (including 902 singletons and 172 contigs), which were searched against the NCBI non-redundant (NR) protein database (E-value cutoff, e(-5)). Based on sequence similarity with known proteins, 579 differentially expressed genes in D. officinale were identified and classified into different functional categories by Gene Ontology (GO), Clusters of orthologous Groups of proteins (COGs) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. The expression levels of 15 selected genes emblematic of symbiotic germination were confirmed via real-time quantitative PCR. These genes were classified into various categories, including defense and stress response, metabolism, transcriptional regulation, transport process and signal transduction pathways. All transcripts were upregulated in the symbiotically germinated seeds (SGS). The functions of these genes in symbiotic germination were predicted. Furthermore, two fungus-induced calcium-dependent protein kinases (CDPKs), which were upregulated 6.76- and 26.69-fold in SGS compared with un-germinated seeds (UGS), were cloned from D. officinale and characterized for the first time. This study provides the first global overview of genes putatively involved in D. officinale symbiotic seed germination and provides a foundation for further functional research regarding symbiotic relationships in orchids.

    Full Text Available Abstract Background Expressed Sequence Tags (ESTs are a source of simple sequence repeats (SSRs that can be used to develop molecular markers for genetic studies. The availability of ESTs for Quercus robur and Quercus petraea provided a unique opportunity to develop microsatellite markers to accelerate research aimed at studying adaptation of these long-lived species to their environment. As a first step toward the construction of a SSR-based linkage map of oak for quantitative trait locus (QTL mapping, we describe the mining and survey of EST-SSRs as well as a fast and cost-effective approach (bin mapping to assign these markers to an approximate map position. We also compared the level of polymorphism between genomic and EST-derived SSRs and address the transferability of EST-SSRs in Castanea sativa (chestnut. Results A catalogue of 103,000 Sanger ESTs was assembled into 28,024 unigenes from which 18.6% presented one or more SSR motifs. More than 42% of these SSRs corresponded to trinucleotides. Primer pairs were designed for 748 putative unigenes. Overall 37.7% (283 were found to amplify a single polymorphic locus in a reference full-sib pedigree of Quercus robur. The usefulness of these loci for establishing a genetic map was assessed using a bin mapping approach. Bin maps were constructed for the male and female parental tree for which framework linkage maps based on AFLP markers were available. The bin set consisting of 14 highly informative offspring selected based on the number and position of crossover sites. The female and male maps comprised 44 and 37 bins, with an average bin length of 16.5 cM and 20.99 cM, respectively. A total of 256 EST-SSRs were assigned to bins and their map position was further validated by linkage mapping. EST-SSRs were found to be less polymorphic than genomic SSRs, but their transferability rate to chestnut, a phylogenetically related species to oak, was higher. Conclusion We have generated a bin map for oak

    Full Text Available A compreensão da diversidade genética fornece elementos básicos sobre a dinâmica e funcionamento de populações, auxiliando na conservação e uso sustentável das espécies. Supõe-se que populações sucessionais precoces poderiam ser geneticamente mais diferenciadas do que populações sucessionais mais tardias. Visando testar esta hipótese, o presente trabalho teve como objetivo analisar a variabilidade genética de populações de Eugenia uniflora L. em manchas florestais em diferentes estádios sucessionais. Foram selecionadas duas áreas em diferentes estádios de sucessão, sendo a primeira em estádio inicial e a segunda em estádio avançado. A área de estudo apresenta um remanescente florestal em transição de Floresta Ombrófila Mista e Floresta Estacional Semidecídua. Por meio da técnica de RAPD (Random Amplified Polymorphic DNA e análise multivariada, a diversidade gênica esperada e a porcentagem de loci polimórficos foram estimadas, além da similaridade genética entre as populações de cada mancha florestal e a diversidade de cada área por meio do índice de diversidade de Simpson. Os resultados indicaram 79% de loci polimórficos para a área em estádio avançado e 70% para a área em estádio inicial de sucessão. A similaridade genética entre pares de indivíduos variou entre 0,55 e 0,86 na área em estádio inicial de sucessão e entre 0,45 e 0,78 para a área em estádio avançado. Não houve diferenças significativas entre a diversidade das duas áreas (P = 89. Um escalonamento multidimensional não-métrico indicou menor distância genética entre os indivíduos da área em estádio inicial. Da mesma forma, uma análise de similaridade - ANOSIM indicou separação entre os indivíduos das duas áreas.

    Random-amplified polymorphic DNA (RAPD) and EST-SSR markers were used to estimate the genetic relationship among thirty-nine P.sojae isolates from three locations in Heilongjiang Province, and nine isolates from Ohio in America were made as reference strains. 10 of 50 RAPD primers and 5 of 33 EST-SSR were polymorphic across 48 P.sojae isolates. Similarity values among P.sojae isolates were from 49% to 82% based on the RAPD data. The similarities based on EST-SSR markers ranged from 47% to 85%. The genetic diversity revealed by EST-SSR marker analysis was higher than that obtained from RAPD. The similarity matrices for the SSR data and the RAPD data were moderately correlated (r = 0.47). Genetic similarity coefficients were also relatively lower, which demonstrated complicated genetic background within each location. The high similarity values range revealed the ability of RAPD/EST-SSR markers to distinguish even among morphological similar phytophthora.

    Full Text Available El ejercicio racional desplegado por los griegos, fundamento del saber filosófico  y científico, se orienta hacia la comprensión del mundo en un audaz esfuerzo por ampliar el horizonte de contemplación y la capacidad de desenvolvimiento de una cultura cosmopolita con una enérgica actividad mercantil. Pero además de la evidencia que puede reunirse acerca de este vinculo indisoluble entre ciencia y filosofía a nivel teórico y metodológico, está presente un ideal estético común que atraviesa las realizaciones del intelecto griego, reorganizando y recomponiendo los elementos provenientes de la observación y la reflexión. Dicho ideal estético cohesiona al pensamiento y le da armonía a la ejecución práctica. De los ocho rasgos destacados del arte griego que señala Gardner en su artículo titulado "Las lámparas del arte griego", tres son, a mi modo de ver, esenciales para percibir la profunda relación que se instaura en la Grecia antigua entre filosofía, ciencia y estética. Estos rasgos esenciales son: Naturalismo, Humanismo y Equilibrio

    Cross-species transferability and expressed sequence tags (ESTs) in public databases are cost-effective means for developing simple sequence repeats (SSRs) for less-studied species like medicinal plants. In this study, 11 EST-SSR markers developed from 742 available ESTs of Withania Somnifera EST sequences and 95 SSR primer pairs derived from other solanaceous crops (tomato, eggplant, chili, and tobacco) were utilized for their amplification and validation. Out of 11, 10 EST-SSRs showed good amplification quality and produced 13 loci with a product size ranging between 167 and 291 bp. Similarly, of the 95 cross-genera SSR loci assayed, 20 (21 %) markers showed the transferability of 5, 27, 32, and 14.2 % from eggplant, chili, tomato, and tobacco, respectively, to ashwagandha. In toto, these 30 SSR markers reported here will be valuable resources and may be applicable for the analysis of intra- and inter-specific genetic diversity in ashwagandha for which till date no information about SSR is available.

  1. Punta del este terrane: meso proterozoic basement and neo proterozoic cover

    Full text: Eastern basement of Uruguay consists of Meso and Neoproterozoic rocks. Mesoproterozoic basement had been deformed by pre-Brasiliano and Brasiliano events. Regional variations in this basement and in the Neoproterozoic cover show equivalent deformation styles and intensities. Models proposed for tectonic evolution have been scarce and confusing. Specially, the ones that concern the moment of collision and/or juxtaposition of blocks. The Punta del Este Terrane (PET) is composed of gneisses and migmatites formed between 1000 Ma to 900 Ma (Preciozzi et al., 2001). These rocks had been strongly reworked during Brasiliano and Rio Doce orogenesis (ca. 900-500 Ma). This crustal segment represents a high grade metamorphic terrane, which is correlated to some gneissic complexes southwest of Africa. Particularly, it is correlated to Kibaran-Namaqua Belt in Namibia. U-Pb ages between 1000 Ma and 900 Ma, obtained in zircons from tonalitic granitoids, are interpreted as indicative of their crystallization (Fig. 1). Besides, anatectic fluids related to migmatites leucosomes yielded ages of ca. 520 to 540 Ma. This denotes that superimposed metamorphic conditions during Brasiliano orogenesis reached, at least, lower amphibolite facies. PET basement gneisses present Sm-Nd model ages (TDM) between 2.4 to 1.8 Ga, showing long crustal residence, corroborated by the very negative εNd values of –1.3 and –14.3. During Brazilian orogenesy they were affected by deformation processes and anatexis. Metasedimentary PET cover occurs near La Paloma and Rocha towns. It is represented by a siliciclastic metasedimentary succession corresponding to the Rocha formation. In La Pedrera town recognized three sedimentary facies were (1-3): (1) sandstones and pelites; (2) green pelites; and (3) rhytmites. The transition from facies (1) to facies (3) shows the passage from fluvial environment with tidal influence to tidal flat with predominance of sub tidal deposits (Pazos and S

    Full Text Available O artigo explora o posicionamento ambivalente de Artigas no debate político-cultural da Guerra Fria, durante a década de 1950, em que se opunham dois movimentos artísticos principais. Por um lado, o realismo socialista, tendência que tomou força na Rússia pós-revolucionária, sobretudo a partir da ascensão de Stalin, ao se colocar como a nova arte das massas proletárias, nas diretrizes da política cultural comum aos diversos partidos comunistas. Por outro lado, o concretismo, já então visto como uma nova vanguarda moderna de abstração geométrica, mas que era atacado pelos militantes comunistas, por seus supostos vínculos “imperialistas”. Para tal, mapeamos o tratamento que o arquiteto deu a cada vertente, em duas fontes simultâneas. Uma se refere aos textos e aulas de Artigas, que permitiram perceber as transformações que as acepções de cada movimento sofreram ao longo de sua carreira. A outra é a de seus projetos, em que estudamos duas casas paradigmáticas: a Olga Baeta, de 1956, e a Rubens de Mendonça, de 1958. Embora a primeira seja normalmente vista como “realista socialista”, e a segunda, como “concretista”, a análise dos desenhos não permite uma vinculação estrita a nenhuma delas. Ambas as posições estão mescladas nas duas casas e são desenvolvidas de modo inconcluso, o que revelaria o impasse cultural em que Artigas se encontrava. Impasse presente nas obras e nos textos,referente não só ao desenvolvimento formal que cada frente lhe abria, como também por suas vinculações a projetos políticos e nacionais de longo alcance.

Algunos de sus proyectos conocidos son Porto Alegre em Cena, Porto Verão Alegre y Serenata Iluminada, además de la Bienal de Artes Visuales del Mercosur, que tuvo su 9ª edición el año de 2013. En ese contexto, la investigación desarrollada visó comprender cómo proyectar estímulos que faciliten a creación de vínculos de los ciudadanos con el arte, en la ciudad de Porto Alegre, partiendo de la experiencia de la 9ª Bienal del Mercosur. Se realizó una investigación de naturaleza exploratória, sobre la experiencia de personas que tienen recurrencia en visitación a la Bienal, por medio de veinte entrevistas en profundidad. Los resultados fueron discutidos a partir de sus potencialidades para fomentar proyectos de diseño aplicado al territorio y ratificaron el potencial que el espacio de la ciudad tiene para estimular la conexión entre personas y arte, lo que puede ser trabajado por instituciones diversas, a partir de intervenciones planeadas.  Además de eso, se observó que el territorio, como objeto projetual de diseño, puede ofrecer no sólo un espacio adecuado para las personas, sino también facilitar la dinámica social que acontece en él. En ese escenario, el factor interacción que se establece entre el territorio, el arte y las personas facilita el desarrollo del vínculo emocional entre la Bienal y los habitantes de la ciudad. La ciudad, como metrópoli permeada por el arte en el periodo de la Bienal, es un fenómeno único, a ser observado. Las conclusiones apuntan que, aunque algunos elementos parecen ser independientes de la ciudad, otros, como el uso de sus espacios característicos, son circunscritos a aspectos marcadamente locales.

    Full Text Available La ilusión causal es un sesgo cognitivo que consiste en la percepción de una relación de causa-efecto entre dos eventos que no están conectados entre sí. Este sesgo podría subyacer algunas creencias irracionales. En un experimento, exploramos la posibilidad de que la creencia en lo paranormal esté asociada a una mayor facilidad para desarrollar ilusiones causales. Los resultados indican que, efectivamente, los creyentes en lo paranormal tienen mayor ilusión causal en una tarea informatizada. Además, esta ilusión fue producida a su vez por un sesgo en la manera en que los creyentes en lo paranormal buscaron información durante la tarea.

    Full Text Available A ideia de beleza - e sua consequente fruição estética - variou conforme as transformações das sociedades humanas, no tempo. Durante a Idade Média, coexistiram diversas concepções de qual era o papel do corpo na hierarquia dos valores estéticos, tanto na Filosofia quanto na Arte. Nossa proposta é apresentar a estética do corpo medieval que alguns filósofos desenvolveram em seus tratados (particularmente Isidoro de Sevilha, Hildegarda de Bingen, João de Salisbury, Bernardo de Claraval e Tomás de Aquino, além de algumas representações corporais nas imagens medievais (iluminuras e esculturas, e assim analisar o tema em três vertentes: a o corpo como cárcere da alma, b o corpo como instrumento, e c o corpo como desregramento.

    Est-Y29, a novel oligomeric class C β-lactamase from a metagenomic library, was crystallized in space group I4 1 and diffraction data were collected to 1.49 Å resolution. β-Lactam antibiotics such as penicillins and cephalosporins have a four-atom ring as a common element in their structure. The β-lactamases, which catalyze the inactivation of these antibiotics, are of great interest because of their high incidence in pathogenic bacteria. A novel oligomeric class C β-lactamase (Est-Y29) from a metagenomic library was expressed, purified and crystallized. The recombinant protein was expressed in Escherichia coli with an N-terminal 6×His tag and purified to homogeneity. EstY-29 was crystallized and X-ray intensity data were collected to 1.49 Å resolution using synchrotron radiation

    The desert locust (Schistocerca gregaria) displays a fascinating type of phenotypic plasticity, designated as 'phase polyphenism'. Depending on environmental conditions, one genome can be translated into two highly divergent phenotypes, termed the solitarious and gregarious (swarming) phase. Although many of the underlying molecular events remain elusive, the central nervous system (CNS) is expected to play a crucial role in the phase transition process. Locusts have also proven to be interesting model organisms in a physiological and neurobiological research context. However, molecular studies in locusts are hampered by the fact that genome/transcriptome sequence information available for this branch of insects is still limited. We have generated 34,672 raw expressed sequence tags (EST) from the CNS of desert locusts in both phases. These ESTs were assembled in 12,709 unique transcript sequences and nearly 4,000 sequences were functionally annotated. Moreover, the obtained S. gregaria EST information is highly complementary to the existing orthopteran transcriptomic data. Since many novel transcripts encode neuronal signaling and signal transduction components, this paper includes an overview of these sequences. Furthermore, several transcripts being differentially represented in solitarious and gregarious locusts were retrieved from this EST database. The findings highlight the involvement of the CNS in the phase transition process and indicate that this novel annotated database may also add to the emerging knowledge of concomitant neuronal signaling and neuroplasticity events. In summary, we met the need for novel sequence data from desert locust CNS. To our knowledge, we hereby also present the first insect EST database that is derived from the complete CNS. The obtained S. gregaria EST data constitute an important new source of information that will be instrumental in further unraveling the molecular principles of phase polyphenism, in further establishing
