    This paper presents a novel evolutionary optimization strategy based on the derandomized evolution strategy with covariance matrix adaptation (CMA-ES). This new approach is intended to reduce the number of generations required for convergence to the optimum. Reducing the number of generations, i.e., the time complexity of the algorithm, is important if a large population size is desired: (1) to reduce the effect of noise; (2) to improve global search properties; and (3) to implement the algorithm on (highly) parallel machines. Our method results in a highly parallel algorithm which scales favorably with large numbers of processors. This is accomplished by efficiently incorporating the available information from a large population, thus significantly reducing the number of generations needed to adapt the covariance matrix. The original version of the CMA-ES was designed to reliably adapt the covariance matrix in small populations but it cannot exploit large populations efficiently. Our modifications scale up the efficiency to population sizes of up to 10n, where n is the problem dimension. This method has been applied to a large number of test problems, demonstrating that in many cases the CMA-ES can be advanced from quadratic to linear time complexity.

    In order to better understand biological events, lectin-glycoprotein interactions are of interest. The possibility to gather more information than the mere positive or negative response for interactions brought mass spectrometry into the center of many research fields. The presented work shows the potential of a nano-electrospray gas-phase electrophoretic mobility molecular analyzer (nES GEMMA) to detect weak, noncovalent, biospecific interactions besides still unbound glycoproteins and unreacted lectins without prior liquid phase separation. First results for Sambucus nigra agglutinin, concanavalin A, and wheat germ agglutinin and their retained noncovalent interactions with glycoproteins in the gas phase are presented. Electrophoretic mobility diameters (EMDs) were obtained by nES GEMMA for all interaction partners correlating very well with molecular masses determined by matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) of the individual molecules. Moreover, EMDs measured for the lectin-glycoprotein complexes were in good accordance with theoretically calculated mass values. Special focus was laid on complex formation for different lectin concentrations and binding specificities to evaluate the method with respect to results obtained in the liquid phase. The latter was addressed by capillary electrophoresis on-a-chip (CE-on-a-chip). Of exceptional interest was the fact that the formed complexes could be sampled according to their size onto nitrocellulose membranes after gas-phase separation. Subsequent immunological investigation further proved that the collected complex actually retained its native structure throughout nES GEMMA analysis and sampling.

  6. A Cbx8-containing polycomb complex facilitates the transition to gene activation during ES cell differentiation.

    Full Text Available Polycomb proteins play an essential role in maintaining the repression of developmental genes in self-renewing embryonic stem cells. The exact mechanism allowing the derepression of polycomb target genes during cell differentiation remains unclear. Our project aimed to identify Cbx8 binding sites in differentiating mouse embryonic stem cells. Therefore, we used a genome-wide chromatin immunoprecipitation of endogenous Cbx8 coupled to direct massive parallel sequencing (ChIP-Seq. Our analysis identified 171 high confidence peaks. By crossing our data with previously published microarray analysis, we show that several differentiation genes transiently recruit Cbx8 during their early activation. Depletion of Cbx8 partially impairs the transcriptional activation of these genes. Both interaction analysis, as well as chromatin immunoprecipitation experiments support the idea that activating Cbx8 acts in the context of an intact PRC1 complex. Prolonged gene activation results in eviction of PRC1 despite persisting H3K27me3 and H2A ubiquitination. The composition of PRC1 is highly modular and changes when embryonic stem cells commit to differentiation. We further demonstrate that the exchange of Cbx7 for Cbx8 is required for the effective activation of differentiation genes. Taken together, our results establish a function for a Cbx8-containing complex in facilitating the transition from a Polycomb-repressed chromatin state to an active state. As this affects several key regulatory differentiation genes this mechanism is likely to contribute to the robust execution of differentiation programs.

    Full Text Available Previously, we have described the development of the generic mobile phone data gathering tool, EpiCollect, and an associated web application, providing two-way communication between multiple data gatherers and a project database. This software only allows data collection on the phone using a single questionnaire form that is tailored to the needs of the user (including a single GPS point and photo per entry, whereas many applications require a more complex structure, allowing users to link a series of forms in a linear or branching hierarchy, along with the addition of any number of media types accessible from smartphones and/or tablet devices (e.g., GPS, photos, videos, sound clips and barcode scanning. A much enhanced version of EpiCollect has been developed (EpiCollect+. The individual data collection forms in EpiCollect+ provide more design complexity than the single form used in EpiCollect, and the software allows the generation of complex data collection projects through the ability to link many forms together in a linear (or branching hierarchy. Furthermore, EpiCollect+ allows the collection of multiple media types as well as standard text fields, increased data validation and form logic. The entire process of setting up a complex mobile phone data collection project to the specification of a user (project and form definitions can be undertaken at the EpiCollect+ website using a simple ‘drag and drop’ procedure, with visualisation of the data gathered using Google Maps and charts at the project website. EpiCollect+ is suitable for situations where multiple users transmit complex data by mobile phone (or other Android devices to a single project web database and is already being used for a range of field projects, particularly public health projects in sub-Saharan Africa. However, many uses can be envisaged from education, ecology and epidemiology to citizen science.

    En ninguna otra época de la historia como en la nuestra se ha producido una transición tan rápida hacia el futuro, en el campo de la medicina.

    Lo que había sido una centuria de evolución desde la era Industrial a la era de la Informática, en la pasada década se ha convertido en una revolución.

    La cirugía laparoscopica que ha constituído el despertar a la edad de la informática como la tecnología lider es considerada ahora un standard en la práctica médica. En la actualidad tecnologias más avanzadas prometen mayores progresos en la medicina.

    La mayor revolución médica ocurrió en la cirugía en las postrimerias del siglo diecinueve cuando algunos gigantes de la medicina todavía caminaban sobre la tierra. Estos visionarios comprendieron la magnitud del cambio y dieron nacimiento a la nueva disciplina de la cirugía. Entre ellos estaban Bilroth, Lister, Virchow y Morton.

    Nunca trabajaron juntos, pero la integración espontánea de sus investigaciones y sus habilidades clínicas hicieron posible la nueva cirugía. Fue la convergencia de sus visiones y sus tecnologias las que dieron un vuelco a la cirugía. Bilroth aportó nuevas técnicas y nuevos instrumentos Lister aportó la asepsia, Virchow la patología y Morton la anestesia.

    Los antiguos mitos y muchos hechos empiricos hicieron creer por miles de años en la inviolabilidad del cuerpo humano. Las herramientas científicas de la Era Industrial convirtieron en realidad lo imposible y la ciencia dio nacimiento a la moderna cirugía. En un corto periodo de tiempo se establecieron los fundamentos de una cirugía que permitiría a las siguientes generaciones liderar nuevos avances y tecnologias.

    Nada estremeció más los fundamentos de la medicina como esta explosión de la cirugía. Comprender el shock, la cirugía cardiaca y coronaria, los trasplantes, tuvieron un enorme impacto que conmocionó la medicina. Es obvio que los cambios producidos

    The term complexity derives etymologically from the Latin plexus, which means interwoven. Intuitively, this implies that something complex is composed by elements that are difficult to separate. This difficulty arises from the relevant interactions that take place between components. This lack of separability is at odds with the classical scientific method - which has been used since the times of Galileo, Newton, Descartes, and Laplace - and has also influenced philosophy and engineering. In recent decades, the scientific study of complexity and complex systems has proposed a paradigm shift in science and philosophy, proposing novel methods that take into account relevant interactions.

    Full Text Available Introduction: performing anal endosonography in complex fistula-in-ano allows us to design a personalized surgical strategy in each case, thereby improving results. However, there are doubts in the literature as to its utility in recurrent complex fistulas. The aim of this study was to compare the utility of anal ultrasonography in the study of primary versus recurrent complex fistula-in-ano. Patients and method: prospective study of patients diagnosed and treated for complex fistula-in-ano. Physical examination and anal ultrasonography provided data on primary track, internal opening, horseshoe extension and the presence of secondary tracks or cavities in a protocol designed specifically for the study. These assessments were subsequently contrasted with operative findings. Results: we included 35 patients, 19 (54.3% with primary complex anal fistulas and 16 (45.7% with recurrent fistulas. According to the operative findings, fistulas were classified as high transsphincteric in 28 patients (80%, suprasphincteric in 6 (17.1% and extrasphincteric in one patient (2.9%, with no differences between groups. Physical examination correctly classified 28 of the 35 fistulous tracks, in contrast to the 32 (91.4% correctly described on ultrasonography (80%. We did not find any statistically significant differences between the primary and the recurrent fistula groups with regard to sensibility, positive predictive value and accuracy of the anal ultrasonography for any of the parameters studied. Conclusion: the accuracy of anal ultrasonography does not decrease in recurrent complex fistula-in-ano.

  12. The Epigenetic Paradox of Pluripotent ES Cells.

    Science.gov (United States)

    Festuccia, Nicola; Gonzalez, Inma; Navarro, Pablo

    2017-05-19

    The propagation and maintenance of gene expression programs are at the foundation of the preservation of cell identity. A large and complex set of epigenetic mechanisms enables the long-term stability and inheritance of transcription states. A key property of authentic epigenetic regulation is being independent from the instructive signals used for its establishment. This makes epigenetic regulation, particularly epigenetic silencing, extremely robust and powerful to lock regulatory states and stabilise cell identity. In line with this, the establishment of epigenetic silencing during development restricts cell potency and maintains the cell fate choices made by transcription factors (TFs). However, how more immature cells that have not yet established their definitive fate maintain their transitory identity without compromising their responsiveness to signalling cues remains unclear. A paradigmatic example is provided by pluripotent embryonic stem (ES) cells derived from a transient population of cells of the blastocyst. Here, we argue that ES cells represent an interesting "epigenetic paradox": even though they are captured in a self-renewing state characterised by extremely efficient maintenance of their identity, which is a typical manifestation of robust epigenetic regulation, they seem not to heavily rely on classical epigenetic mechanisms. Indeed, self-renewal strictly depends on the TFs that previously instructed their undifferentiated identity and relies on a particular signalling-dependent chromatin state where repressive chromatin marks play minor roles. Although this "epigenetic paradox" may underlie their exquisite responsiveness to developmental cues, it suggests that alternative mechanisms to faithfully propagate gene regulatory states might be prevalent in ES cells.

    La palabra Arquitectura para nosotros tiene una significación obvia, e incluso podríamos considerar que es una palabra reservada, es decir, que no debe emplearse en otro contexto; en realidad se emplea en el sentido de Orden Superior. La arquitectura de microprocesadores es un ejemplo del empleo del término con sentido bastante alejado del nuestro.

    Full Text Available The sense or meaning of a word resides in thought and only manifests itself when the word is used. Yet the sense conveyed can be equivocal if the word is taken out of its context, spatial as well as temporal. Considering the present time then, we are dealing with the determination of a space, with exploring around the contextual area. The study that resulted in this paper involves geography, but is no geographical research; at most research on human geography. Although it involves speech, its direct object is not language. Neither it is, in strictness, ethnography nor cultural anthropology. But it concerns all of these fields and, therefore, cannot stay away from any of them. Only one concept, perhaps, overrides the whole undertaking and meets the double condition of being simple and complex at the same time: the concept of elementary area. This concept rests upon the seminal idea of taking the sense and meaning of something (in this case, a name or a noun as the use given to such something (such name or noun in a particular space: a here and a now. One word or signifier, one single meaning; that is all there is. Yet it is this extreme simplification that which allows freedom of speculation, clear and refined.

    El sentido de una palabra está en el pensamiento y sólo se hace manifiesto a través de dicha palabra. Pero la información que conlleva la misma es equívoca si hacemos abstracción de un lugar y de un tiempo. Sea el tiempo actual. Se trata, pues, de la determinación de un lugar, de indagar acerca del territorio. El estudio propuesto trata, pues, de geografía, pero no es geografía; acaso geografía humana. Concierne al habla, pero su objeto directo no es la lengua. No es tampoco, en sentido estricto, etnografía ni antropología cultural. Pero siendo un poco todo ello, no puede prescindir de nada. Sólo uno de sus conceptos, quizá, presida todo el conjunto y reúna la doble condición de ser complejo y a la vez simple:

Albert Einstein était un écrivain prolifique dont l'œuvre abonde en aphorismes. Les 550 citations de ce recueil, tirées des quelque 40 000 documents des Archives Einstein, nous font découvrir le Einstein de la légende, l'ami des écoliers et des étudiants fauchés, le philosophe de la vie quotidienne, doux et ironique, mais aussi la face plus sombre, parfois désespérée, de ce grand génie de l'ère moderne.

    2013-12-01

    Earth System Documentation (ES-DOC) is an international project supplying high-quality tools & services in support of earth system documentation creation, analysis and dissemination. It is nurturing a sustainable standards based documentation eco-system that aims to become an integral part of the next generation of exa-scale dataset archives. ES-DOC leverages open source software, and applies a software development methodology that places end-user narratives at the heart of all it does. ES-DOC has initially focused upon nurturing the Earth System Model (ESM) documentation eco-system and currently supporting the following projects: * Coupled Model Inter-comparison Project Phase 5 (CMIP5); * Dynamical Core Model Inter-comparison Project (DCMIP); * National Climate Predictions and Projections Platforms Quantitative Evaluation of Downscaling Workshop. This talk will demonstrate that ES-DOC implements a relatively mature software development process. Taking a pragmatic Agile process as inspiration, ES-DOC: * Iteratively develops and releases working software; * Captures user requirements via a narrative based approach; * Uses online collaboration tools (e.g. Earth System CoG) to manage progress; * Prototypes applications to validate their feasibility; * Leverages meta-programming techniques where appropriate; * Automates testing whenever sensibly feasible; * Streamlines complex deployments to a single command; * Extensively leverages GitHub and Pivotal Tracker; * Enforces strict separation of the UI from underlying API's; * Conducts code reviews.

    2009-01-01

    We have been able to develop a stable nuclear transfer (NT) method in the mouse, in which donor nuclei are directly injected into the oocyte using a piezo-actuated micromanipulator. Although the piezo unit is a complex tool, once mastered it is of great help not only in NT experiments, but also in almost all other forms of micromanipulation. Using this technique, embryonic stem (ntES) cell lines established from somatic cell nuclei can be generated relatively easily from a variety of mouse genotypes and cell types. Such ntES cells can be used not only for experimental models of human therapeutic cloning but also as a means of preserving mouse genomes instead of preserving germ cells. Here, we describe our most recent protocols for mouse cloning.

    We previously reported that Zscan4 showed heterogeneous expression patterns in mouse embryonic stem (ES) cells. To identify genes that show similar expression patterns, we carried out high-throughput in situ hybridization assays on ES cell cultures for 244 genes. Most of the genes are involved in transcriptional regulation, and were selected using microarray-based comparisons of gene expression profiles in ES and embryonal carcinoma (EC) cells versus differentiated cell types. Pou5f1 (Oct4, Oct3/4) and Krt8 (EndoA) were used as controls. Hybridization signals were detected on ES cell colonies for 147 genes (60%). The majority (136 genes) of them showed relatively homogeneous expression in ES cell colonies. However, we found that two genes unequivocally showed Zscan4-like spotted expression pattern (spot-in-colony pattern; Whsc2 and Rhox9). We also found that nine genes showed relatively heterogeneous expression pattern (mosaic-in-colony pattern: Zfp42/Rex1, Rest, Atf4, Pa2g4, E2f2, Nanog, Dppa3/Pgc7/Stella, Esrrb, and Fscn1). Among these genes, Zfp42/Rex1 showed unequivocally heterogeneous expression in individual ES cells prepared by the CytoSpin. These results show the presence of different types or states of cells within ES cell cultures otherwise thought to be undifferentiated and homogeneous, suggesting a previously unappreciated complexity in ES cell cultures.

    Full Text Available La definición de la Psicología como ciencia de la conducta adoptada por el Conductismo supone e implica a su vez una conceptualización clara y unívoca de dicho concepto. Pero tal definición se enfrenta con una serie de malentendidos tenaces que dificultan no sólo la comprensión de dicho concepto básico sino también, en consecuencia, la propia conceptualización conductista. El propósito del presente trabajo es intentar exponer algunos de estos malentendidos, entre los que destacan los errores categoriales groseros, los procesos de reificación abusiva, los razonamientos tautológicos disfrazados, la generalización imprudente del modelo médico al ámbito de la conducta y la confusión nefasta entre un fenómeno y su conceptualización. Para ello, y con un tono más didáctico que académico, se recurre a una serie de metáforas de la vida cotidiana: la parte escondida del iceberg no es más que iceberg, las piedras no caen por su propio peso, los hombres y las mujeres no mueren porque son mortales, el bacilo de Koch existe y la máscara no es el rostro.

    Full Text Available El levantamiento chiapaneco del primero de enero de 1994 descencadenó la movilización de varios sectores de la sociedad mexicana. Del repudio unánime a la guerra nació un amplio movimiento ciudadano y popular que –sin compartir los medios tácticos de la lucha armada– convergió con el Ejército Zapatista de Liberación Nacional (EZLN en sus aspiraciones sociales y políticas: la lucha por la democracia, la justicia y la libertad. Por ser él, resulta pertinente calificarlo con el término de neozapatismo civil. Si sumamos a este conjunto de movilizaciones ciudadanas y populares el propio zapatismo armado – advirtiendo su carácter «socio-políticomilitar »– obtendremos el neozapatismo en su sentido más amplio. Otra forma de entender el neozapatismo –que desarrollaremos en la presente reflexión– es como un proceso dinámico constituido por una pluralidad de intereses, voluntades e identidades, que lo inscriben dentro de un campo de contradicciones y de tensiones no resueltas. Como primera premisa podemos apuntar que el neozapatismo no es ni homogéneo ni mucho menos monolítico, sino que, como lo mostraremos a continuación, tiene una naturaleza multifacética, polisémica y fluídica.

    In XVIIIth century on Encyclopaedists influence, the study of Sciences arouse a real passion. Many courses are proposed. Two private institutions are opened which are called "Lycées": "Lycée de la rue de Valois" and "Lycée des Arts". Fourcroy and Lavoisier have been influential members of these two. Problems come to "Lycée de la rue de Valois", lead to the "purge ballot" and to Lavoisier's eviction. In France, it is the "Terror" and Lavoisier few months after was guillotined as "Fermier general". The historic events exonerate Fourcroy, member of the Convention, to the accusation that he has no made steps to save Lavoisier. This important historic event is a part of this study. As we show in this study "Lycées" are been small universities and have contributed to maintenance bonds between French scientists at the Revolution. The "Musée de Paris" and the "Société Philomathique de Paris" are also evoked.

O diagnóstico dessa neoplasia pode ser feito tanto por citologia como por histopatologia, embora, muitas vezes, sua diferenciação de leucemia linfóide seja difícil. Vários sinais clínicos são associados com o linfossarcoma canino, a maioria deles relacionada ao órgão na qual o tumor se localiza. Uma manifestação comum é a linfadenopatia generalizada que deve ser diferenciada de outras enfermidades que causam aumento de volume dos linfonodos. Algumas síndromes paraneoplásicas complicam casos de linfossarcoma e, muitas vezes, são responsáveis pela morte do animal.

    Full Text Available Tolerance is a basic value of our democracies, when it applies to life attitudes and to symbolic interpretations of our experience. However, usually there is no tolerance about statements of fact offered without scientific basis or from assumptions that proved to be false. Religions have a symbolic and poetic dimension which is not only tolerable, but even also fruitful for the interpretation of our life, but they also tend to present themselves as explanations of facts in competition with scientific explanations. It can be argued whether complete tolerance of this second use of religious ideology should be encouraged.

    La tolerancia es un valor básico de nuestras democracias, en cuanto se refiere a actitudes vitales y a interpretaciones simbólicas de nuestra experiencia. No suele haber tolerancia, en cambio, sobre las cuestiones de hecho presentadas sin base científica o desde presupuestos comprobadamente falsos. Las religiones tienen una dimensión poética y simbólica no sólo tolerable sino hasta enriquecedora de nuestra interpretación vital, pero casi siempre pretenden presentarse también como explicaciones de los hechos en competencia con la de los científicos. Puede cuestionarse si debe haber plena tolerancia para este segundo uso de la ideología religiosa.

    Full Text Available Aborder le thème des violences sexuelles et sexuées, c’est toucher à des schèmes de pensées différents, à des domaines et des notions variés, cela met en jeu des interprétations parfois contradictoires. Et pourtant, assez paradoxalement, ce thème si difficile à circonscrire est souvent présenté comme simple, univoque, allant de soi, remplacé parfois abusivement dans le langage courant par le mot viol. Les violences sexuelles sont des agressions en rapport avec la sexualité de l’agresseur et d...

  14. Advanced boundary electrode modeling for tES and parallel tES/EEG

    CERN Document Server

    Agsten, Britte; Pursiainen, Sampsa; Wolters, Carsten H

    2016-01-01

    This paper explores advanced electrode modeling in the context of separate and parallel transcranial electrical stimulation (tES) and electroencephalography (EEG) measurements. We focus on boundary condition based approaches that do not necessitate adding auxiliary elements, e.g. sponges, to the computational domain. In particular, we investigate the complete electrode model (CEM) which incorporates a detailed description of the skin-electrode interface including its contact surface, impedance and normal current distribution. The CEM can be applied for both tES and EEG electrodes which is advantageous when a parallel system is used. In comparison to the CEM, we test two important reduced approaches: the gap model (GAP) and the point electrode model (PEM). We aim to find out the differences of these approaches for a realistic numerical setting based on the stimulation of the auditory cortex. The results obtained suggest, among other things, that GAP and GAP/PEM are sufficiently accurate for the practical appli...

    Wielicki, Bruce A. (Principal Investigator)

    The ERBE-like Monthly Geographical Averages (ES-4) product contains a month of space and time averaged Clouds and the Earth's Radiant Energy System (CERES) data for a single scanner instrument. The ES-4 is also produced for combinations of scanner instruments. For each observed 2.5-degree spatial region, the daily average, the hourly average over the month, and the overall monthly average of shortwave and longwave fluxes at the Top-of-the-Atmosphere (TOA) from the CERES ES-9 product are spatially nested up from 2.5-degree regions to 5- and 10-degree regions, to 2.5-, 5-, and 10-degree zonal averages, and to global monthly averages. For each nested area, the albedo and net flux are given. For each region, the daily average flux is estimated from an algorithm that uses the available hourly data, scene identification data, and diurnal models. This algorithm is 'like' the algorithm used for the Earth Radiation Budget Experiment (ERBE).

    One response of the UK research community to the public sensitivity and logistical complexity of embryo donation to stem cell research has been the formation of a national network of 'human embryonic stem cell coordinators' (hESCCO). The aim of hESCCO is to contribute to the formation and implementation of national standards for hES cell derivation and banking, in particular the ethical protocols for patient information and informed consent. The hESCCO project is an innovative practical intervention within the broader attempt to establish greater transparency, consistency, efficiency and standardization of hES derivation in the UK. A major outcome of the hESCCO initiative has been the drafting and implementation of a national consent form. The lessons learned in this context may be relevant to other practitioners and regulators as a model of best practice in hES cell derivation.

    2006-11-09

    Here we demonstrate how our lab begins a HuES human embryonic stem cell line culture from a frozen stock. First, a one to two day old ten cm plate of approximately one (to two) million irradiated mouse embryonic fibroblast feeder cells is rinsed with HuES media to remove residual serum and cell debris, and then HuES media added and left to equilibrate in the cell culture incubator. A frozen vial of cells from long term liquid nitrogen storage or a -80 C freezer is sourced and quickly submerged in a 37 C water bath for quick thawing. Cells in freezing media are then removed from the vial and placed in a large volume of HuES media. The large volume of HuES media facilitates removal of excess serum and DMSO, which can cause HuES human embryonic stem cells to differentiate. Cells are gently spun out of suspension, and then re-suspended in a small volume of fresh HuES media that is then used to seed the MEF plate. It is considered important to seed the MEF plate by gently adding the HuES cells in a drop wise fashion to evenly disperse them throughout the plate. The newly established HuES culture plate is returned to the incubator for 48 hrs before media is replaced, then is fed every 24 hours thereafter.

    Delipidation in biological samples is important for some diagnostic tests and protein analyses. Lipids in the samples can be hydrolyzed by native esterases (ESs) within gel capsules after ES, and ES-antibody complexes are specifically trapped, extracted, and separated. Acrylamide and agarose gel capsules containing complexes of ES antibody were produced after the complexes were extracted using protein A-immobilized membranes, separated by non-denaturing electrophoresis, and stained by colloidal silver using glucose as a reductant. ES activity of ES-antibody complexes within the gel capsule was significantly higher than that in the complexes with the control antibodies upon isolation, separation, and detection of the complex. In addition, lipids bound to human serum albumin decreased after human plasma was treated with gel capsules containing ES-antibody complexes. We demonstrate that the gel capsule containing ES-antibody complexes can be successfully isolated using techniques described in this study. Furthermore, delipidation of human plasma is obtained by incubation with the gel capsule. These results indicate that surplus materials such as lipids in biological samples can be removed or reduced by gel capsule containing enzymes.

Currently, bone marrow cells and cord blood cells are used for transplantation into patients with hematopoietic malignancies, immunodeficiencies and in some cases for the treatment of autoimmune diseases. However, due to the high immunogenicity of these hematopoietic cells, toxic regimens of drugs are required for preconditioning and prevention of rejection. Here, we investigated the efficiency of deriving hematopoietic progenitor cells (HPCs from the hES cell line H13, after co-culturing with the murine stromal cell line OP9. We show that HPCs derived from the H13 ES cells poorly express major histocompatibility complex (MHC class I and no detectable class II antigens (HLA-DR. These characteristics make hES cell-derived hematopoietic cells (HPCs ideal candidates for transplantation across MHC barriers under minimal immunosuppression.Keywords: human embryonic stem cells, H13, hematopoiesis, OP9 stromal cells, immunogenicity

    Full Text Available Hepatic and pancreatic differentiation from ES cells is of great interest for the impact that this knowledge could have on the treatment of hepatic and diabetic patients. The liver and pancreas initially develop by budding from the embryonic endoderm. Thus, the development of the endoderm represents an important step and has an integral common role in initiating the early stages of pancreatic and liver development. We know that the development of hepatocytes and insulin-producing pancreatic beta-cells from ES cells represents the culmination of a complex developmental program. However, there has been recent progress in directing ES cells to endoderm and early-stage hepatic and pancreatic progenitor cells. We here discuss the role of the microenvironment, transcriptional factors and cytokines, which have been recognized as important molecules during the major steps of the development of the liver and pancreas. We also present the most recent advances and efforts taken to produce definitive endoderm-committed ES cells for the further differentiation of hepatocyte-like and insulinproducing cells. Recent progress in the search for new sources of hepatocytes and beta-cells has opened up several possibilities for the future of new perspectives for future of new prophylactic and therapeutic possibilities for liver diseases and diabetes.

    We report new spectroscopic and photometric observations of the parent stars of the recently discovered transiting planets TrES-3 and TrES-4. A detailed abundance analysis based on high-resolution spectra yields [Fe/H] $= -0.19\\pm 0.08$, $T_\\mathrm{eff} = 5650\\pm 75$ K, and $\\log g = 4.4\\pm 0.1$ for TrES-3, and [Fe/H] $= +0.14\\pm 0.09$, $T_\\mathrm{eff} = 6200\\pm 75$ K, and $\\log g = 4.0\\pm0.1$ for TrES-4. The accuracy of the effective temperatures is supported by a number of independent consistency checks. The spectroscopic orbital solution for TrES-3 is improved with our new radial-velocity measurements of that system, as are the light-curve parameters for both systems based on newly acquired photometry for TrES-3 and a reanalysis of existing photometry for TrES-4.

    Full Text Available The loss in muscle mass coupled with a decrease in specific force and shift in fiber composition are all marks of aging. Training and regular exercise attenuate the signs of sarcopenia. However, pathologic conditions limit the ability to perform physical exercise.We addressed whether electrical stimulation (ES is an alternative intervention to improve muscle recovery and defined the molecular mechanism associated with improvement in muscle structure and function.We analyzed, at functional, structural, and molecular level, the effects of ES training on healthy seniors with normal life style, without routine sport activity.ES was able to improve muscle torque and functional performances of seniors and increased the size of fast muscle fibers. At molecular level, ES induced up-regulation of IGF-1 and modulation of MuRF1, a muscle-specific atrophy-related gene. ES also induced up-regulation of relevant markers of differentiating satellite cells and of extracellular matrix remodeling, which might guarantee shape and mechanical forces of trained skeletal muscle as well as maintenance of satellite cell function, reducing fibrosis.Our data provide evidence that ES is a safe method to counteract muscle decline associated with aging.

    Full Text Available Nicaragua es un país con un nivel de escolarización relativamente bajo y el contexto material y social en las escuelas hace que la enseñanza de la lengua materna esté dominada por métodos de memorización y ejercicios de gramática del tipo “rellenar espacios”. Las formas de tratamiento escritas que se utilizan en contextos pedagógicos son únicamente el tú y el usted, a pesar de ser Nicaragua una zona voseante. El presente artículo pretenderá mostrar, a través de referencias a estudios sobre las formas de tratamiento en Nicaragua, análisis del uso de los tratamientos en la escritura, ejemplos de entrevistas de actitudes lingüísticas y de análisis de documentos pedagógicos, que hay una discrepancia entre la norma escrita y la norma hablada en cuanto a las formas de tratamiento tú y vos en Nicaragua. Esta discrepancia se puede explicar con las creencias en torno a las diferentes formas de tratamiento, pero también al revés: el uso contradictorio de parte de las autoridades educativas influirá en las creencias del pueblo en general acerca de las formas de tratamiento y así crece un clima de inseguridad de la corrección de su propia habla. En última instancia tal contradicción puede ser un obstáculo para la enseñanza de la lengua materna y el prestigio lingüístico del habla local.

    We present the analysis and results of recent high-energy gamma-ray observations of the high energy-peaked BL Lac (HBL) object 1ES 1218+304 with the Solar Tower Atmospheric Cherenkov Effect Experiment (STACEE). 1ES 1218+304 is an X-ray bright HBL at a redshift z=0.182. It has been predicted to be a gamma-ray emitter above 100 GeV, detectable by ground-based Cherenkov telescopes. Recently this source has been detected by MAGIC and VERITAS, confirming these predictions. STACEE's sensitivity to astrophysical sources at energies above 100 GeV allows it to explore high energy sources such as X-ray bright active galaxies and gamma-ray bursts. We present results from STACEE observations of 1ES 1218+304 in the 2006 and 2007 observing seasons.

    Freistetter, Florian; Funk, Barbara

    2009-01-01

    The TrES-2 system harbors one planet which was discovered with the transit technique. In this work we investigate the dynamical behavior of possible additional, lower-mass planets. We identify the regions where such planets can move on stable orbits and show how they depend on the initial eccentricity and inclination. We find, that there are stable regions inside and outside the orbit of TrES-2b where additional, smaller planets can move. We also show that those planets can have a large orbital inclination which makes a detection with the transit technique very difficult.

    2015-12-01

    century, the parisian perfumery of Sarah Felix was famous especially for her cosmetic "L'Eau des Fées" ("Water of the Fairies"), a dyeing supposed to give back to the old hair the color of their youth. Sarah Felix, sister of the famous actress Rachel, exercised several jobs before becoming perfumer. At first, she was actress, then she tried ... oyster culture in Normandy ! Abandoning these activities, Sarah Felix became really a businesswoman in Paris. She dedicated herself to perfumery, in particular to "L'Eau des Fées", from 1866. To launch its product, she was associated to competency characters (engineer, pharmacist, physician) and benefited from the protection of the imperial family. A lawsuit between the associates and the 1870 war hindered the company's early days, but "L'Eau des Fées" provided with quality pledges, imposed itself definitely. The "Parfumerie des Fées" completed the range of its cosmetics with creams, powders, etc. Sarah Félix paid attention to present "L'Eau des Fées" as a dye devoid of toxicity. Was it really the case and could il be sold nowadays? These two issues are discussed in the last part.

    2013-12-01

    Full Text Available Le présent article sʼintéresse aux caractéristiques des erreurs dans les dictées des étudiants slovènes de français. La raison pour laquelle nous avons choisi dʼanalyser les dictées consiste dans le fait que la dictée est un exercice assez complexe car elle met à lʼépreuve aussi bien la compréhension orale de lʼapprenant que ses connaissances en orthographe et en règles grammaticales. Dans un premier temps, nous nous sommes plus particulièrement intéressés à lʼapparition de certains types dʼerreurs. Dans ce but, nous avons établi un classement des erreurs qui avait pour mission de répertorier différents types dʼerreurs que lʼon peut trouver dans ce type de discours écrit. Ensuite, nous nous sommes penchés sur les causes possibles de ces erreurs pour finalement proposer quelques pistes susceptibles dʼy remédier. Lʼanalyse des dictées a démontré que les erreurs plus nombreuses proviennent de lʼorthographe dʼusage, suivent les erreurs de nature lexicale et lʼoubli dʼun mot ou dʼun syntagme. Parmi les principales causes de ces types dʼerreurs, on pourrait mentionner une orthographe française difficile, un vocabulaire insuffisant et un manque dʼautomatismes. Pour diminuer au maximum le nombre dʼerreurs dans les dictées, lʼengagement, la persistance et une participation active de la part de lʼapprenant semblent indispensables. Sans oublier, bien sûr, une approche efficace du professeur, qui proposera différentes activités qui auront pour but dʼaméliorer leurs compétences langagières sollicitées dans les dictées.

  17. Early specification of dopaminergic phenotype during ES cell differentiation

    Directory of Open Access Journals (Sweden)

    Li Meng

    2007-07-01

    Full Text Available Abstract Background Understanding how lineage choices are made during embryonic stem (ES cell differentiation is critical for harnessing strategies for controlled production of therapeutic somatic cell types for cell transplantation and pharmaceutical drug screens. The in vitro generation of dopaminergic neurons, the type of cells lost in Parkinson's disease patients' brains, requires the inductive molecules sonic hedgehog and FGF8, or an unknown stromal cell derived inducing activity (SDIA. However, the exact identity of the responding cells and the timing of inductive activity that specify a dopaminergic fate in neural stem/progenitors still remain elusive. Results Using ES cells carrying a neuroepithelial cell specific vital reporter (Sox1-GFP and FACS purification of Sox1-GFP neural progenitors, we have investigated the temporal aspect of SDIA mediated dopaminergic neuron specification during ES cell differentiation. Our results establish that SDIA induces a dopaminergic neuron fate in nascent neural stem or progenitor cells at, or prior to, Sox1 expression and does not appear to have further instructive role or neurotrophic activity during late neuronal differentiation of neural precursors. Furthermore, we show that dopaminergic neurons could be produced efficiently in a monolayer differentiation paradigm independent of SDIA activity or exogenous signalling molecules. In this case, the competence for dopaminergic neuron differentiation is also established at the level of Sox1 expression. Conclusion Dopaminergic neurons are specified early during mouse ES cell differentiation. The subtype specification seems to be tightly linked with the acquisition of a pan neuroectoderm fate.

    We present the development of a parallel Markov Chain Monte Carlo (MCMC) method called SAChES, Scalable Adaptive Chain-Ensemble Sampling. This capability is targed to Bayesian calibration of com- putationally expensive simulation models. SAChES involves a hybrid of two methods: Differential Evo- lution Monte Carlo followed by Adaptive Metropolis. Both methods involve parallel chains. Differential evolution allows one to explore high-dimensional parameter spaces using loosely coupled (i.e., largely asynchronous) chains. Loose coupling allows the use of large chain ensembles, with far more chains than the number of parameters to explore. This reduces per-chain sampling burden, enables high-dimensional inversions and the use of computationally expensive forward models. The large number of chains can also ameliorate the impact of silent-errors, which may affect only a few chains. The chain ensemble can also be sampled to provide an initial condition when an aberrant chain is re-spawned. Adaptive Metropolis takes the best points from the differential evolution and efficiently hones in on the poste- rior density. The multitude of chains in SAChES is leveraged to (1) enable efficient exploration of the parameter space; and (2) ensure robustness to silent errors which may be unavoidable in extreme-scale computational platforms of the future. This report outlines SAChES, describes four papers that are the result of the project, and discusses some additional results.

    The scope of this work is to conduct the cross-cultural adaptation from Spanish to European Portuguese of a questionnaire to measure the degree of "Patient Knowledge about their Medications" (CPM-ES-ES). A method based on six steps was applied: 1. Translation into Portuguese, 2. Elaboration of the first consensus version in Portuguese; 3.Back-translation into Spanish; 4. Elaboration of the second consensus version (cultural equivalency); 5. Conducting the pre-test; 6. Evaluation of the overall results. A cross-culturally adapted questionnaire in European Portuguese that measures the degree of "Patient Knowledge about their Medications" is proposed. The pre-test confirmation obtained 100% agreement with the corrected version of the second consensus version after pre-testing. The methodology selected made it possible to cross-culturally adapt the Spanish version of the CPM-ES-ES questionnaire to the Portuguese version. Further studies should demonstrate the equivalence of the psychometric properties of the cross-cultural translation into Portuguese with the original version.

    Full Text Available In this text, which comes from Chapter 3 of his book, Jacques Le Mouel completes the philosophical reflection about the entrepreneurial myth of effectiveness founded in the sophism: "What is effective is true. What is true is faie. Therefore, what is effective is fair". The fact that management is elevated to the category of paradigm for the economic model of Western society and the collapse of the economies of the East has led to neglect that, now, we ourselves are the modelo His analysis of the supposed neutrality of science and of the differences between ethics and morality, in the framework of the firm and its relations with society, lead him to conclude that it is not true that what is effective is fair, and that the firm cannot serve as a model for contemporary society, since the end does not justify the means.En este texto, que corresponde al capitulo 3 de su libro, Jaques Le Mouël completa la reflexión filosófica sobre el mito empresarial de la eficacia funadado en el sofisma: "Lo eficaz es verdadero. Lo verdadero es justo. Luego, lo eficaz es justo". El hecho de elevar la administración a la categoría de paradigma del modelo económico de la sociedad occidental y el hundimiento de las economías del Este han llevado a ignorar que, ahora, el modelo somos nosotros mismos. Su análisis de la pretendida neutralidad de la ciencia y las diferencias entre ética y moral, en el marco de la empresa y en sus relaciones con la sociedad, lo lleva a concluir que no es cierto que lo eficaz sea justo y que la empresa no puede servir de modelo a la sociedad contemporánea, pues el fin no justifica los medios.

  18. [History of the Journées Dermatologiques de Paris].

    Tilles, G

    2013-12-01

    Founded in 1801 at the Hôpital Saint-Louis, Paris, under Jean-Louis Alibert, the French School of Dermatology was initially structured around the French Society of Dermatology (1889) and the organization of two world congresses (Paris 1889, 1900). After World War I, the creation of dermatological societies in the provinces infused French dermatology with new energy. In 1922, the first congress of the French-speaking dermatologists further contributed to the public profile of dermatologists in France. The "Journées de Mars" were initiated in 1961 at the Hôpital Saint-Louis, and in 1975 they went on to become the "Journées dermatologiques de Paris". Pr. Jean Civatte played a key role in their creation and in their organization for 30 years. After 1979, since actual patients could no longer be presented, the organizers of the congress had to change the content of the meeting from clinical presentations to post-graduate teaching and clinical research. From its origins in the form of meetings of French dermatologists in an intimate setting at the Hôpital Saint-Louis, the "Journées dermatologiques de Paris" grew within the ensuing decades into a major scientific event of the French-speaking dermatological community, bringing together more than 4000 participants in December each year.

    2012-01-01

    Full Text Available La Clasificación Internacional de las Enfermedades (CIE de la Organización Mundial de Salud (OMS es muy poco conocida en el ámbito de la psicología en España, y existe la falsa percepción de que su importancia es escasa en el campo de la salud mental. El propósito de este artículo es familiarizar a los psicólogos y otros profesionales en salud mental con el sistema de clasificación CIE, algo especialmente relevante al encontrarse actualmente en proceso de revisión. La OMS está haciendo un gran esfuerzo para crear una clasificación de trastornos mentales global, multicultural y multidisciplinar, centrándose en mejorar su utilidad clínica. Además, en la actual revisión de la CIE, la OMS ha adoptado el español como segunda lengua de trabajo, lo que da una gran oportunidad a los profesionales de la salud mental de España y otros países hispanohablantes de implicarse activamente en el desarrollo de la próxima versión de la clasificación. Es importante que los psicólogos de países hispanohablantes conozcan la CIE y entiendan los grandes beneficios que pueden aportarles su conocimiento y utilización para integrarse plenamente como profesión sanitaria oficial, así como para equipararse en la práctica de la psicología al resto de Europa y de todo el mundo en términos de diagnóstico y clasificación de los trastornos mentales.

  4. Bucolic Complexes

    CERN Document Server

    Brešar, Bostjan; Chepoi, Victor; Gologranc, Tanja; Osajda, Damian

    2012-01-01

    In this article, we introduce and investigate bucolic complexes, a common generalization of systolic complexes and of CAT(0) cubical complexes. This class of complexes is closed under Cartesian products and amalgamations over some convex subcomplexes. We study various approaches to bucolic complexes: from graph-theoretic and topological viewpoints, as well as from the point of view of geometric group theory. Bucolic complexes can be defined as locally-finite simply connected prism complexes satisfying some local combinatorial conditions. We show that bucolic complexes are contractible, and satisfy some nonpositive-curvature-like properties. In particular, we prove a version of the Cartan-Hadamard theorem, the fixed point theorem for finite group actions, and establish some results on groups acting geometrically on such complexes. We also characterize the 1-skeletons (which we call bucolic graphs) and the 2-skeletons of bucolic complexes. In particular, we prove that bucolic graphs are precisely retracts of Ca...

  5. Disposal frequencies of selected recyclable wastes in Dar es Salaam.

    Mgaya, Prosper; Nondek, Lubomir

    2004-01-01

    A statistical survey of households based upon questionnaires distributed via primary schools has been carried out in five wards of Dar es Salaam, Tanzania, to estimate disposal frequencies (number of items disposed per week) for newsprint, metal cans, glass and plastic containers and plastic shopping bags. Plastic shopping bags are disposed most frequently while glass containers are disposed least frequently. The statistical distribution of disposal frequencies, which seems to be influenced by household income, is well described by Poisson distribution. Disposal frequencies are mutually correlated at 95% level of probability despite the differences in disposal patterns of individual households.

    Este estudio se propone explicar el Vudú, esa religión mal conocida, desprestigiada, tergiversada por las revistas, los libros, las películas que se dicen serias y objetivas. De manera sistemática y con gran sensacionalismo, los medios extranjeros han contribuido a presentarla constantemente como una horrible acumulación de groseras supersticiones, orgías sexuales, magia negra, brujería y maleficios. Sin embargo, el Vudú haitiano no es sólo una religión recreada por los esclavos africanos ...

  15. Adaptive cancellation of Es layer interference using auxiliary horizontal antennas

    Institute of Scientific and Technical Information of China (English)

    Zhao Long; Zhang Ning

    2006-01-01

    Based on a dual-polarization high-frequency wave radar system, an adaptive system using horizontal antennas for the suppression of the Es layer interference (ELI) is described. The data received from the horizontal antennas were correlated with the data received from the Vertically Polarized Antennas (VPAs) to estimate and cancel the interference adaptively in the VPAs. Suppressing the interference after each coherent integration time interval, about 25 dB signal-to-interference ratio is expected with the experimentally derived data.

    Full Text Available Abstract Background The RNA binding protein, DEAD END (DND1, is essential for maintaining viable germ cells in vertebrates. It is also a testicular germ cell tumor susceptibility factor in mice. DND1 has been shown to interact with the 3'-untranslated region (3'-UTR of mRNAs such as P27 and LATS2. Binding of DND1 to the 3'-UTRs of these transcripts blocks the inhibitory function of microRNAs (miRNA from these transcripts and in this way DND1 helps maintain P27 and LATS2 protein expression. We found that DND1 is also expressed in embryonic stem (ES cells. Because ES cells share similar gene expression patterns as germ cells, we utilized ES cells to identify additional candidate mRNAs that associate with DND1. Results ES cells are readily amenable to genetic modification and easier to culture in vitro compared to germ cells. Therefore, for the purpose of our study, we made a genetically modified, stable, human embryonic stem (hES cell line that expresses hemagluttinin (HA-tagged DND1 in a doxycycline (dox regulatable manner. This line expresses modest levels of HA-DND1 and serves as a good system to study DND1 function in vitro. We used this stable cell line to identify the transcripts that physically interact with DND1. By performing ribonucleoprotein immunoprecipitation (RIP followed by RT-PCR, we identified that transcripts encoding pluripotency factors (OCT4, SOX2, NANOG, LIN28, cell cycle regulators (TP53, LATS2 and apoptotic factors (BCLX, BAX are specifically associated with the HA-DND1 ribonucleoprotein complex. Surprisingly, in many cases, bioinformatics analysis of the pulled-down transcripts did not reveal the presence of known DND1 interacting motifs. Conclusions Our results indicate that the inducible ES cell line system serves as a suitable in vitro system to identify the mRNA targets of DND1. The RIP-RT results hint at the broad spectrum of mRNA targets that interact with DND1 in ES cells. Based on what is known about DND1 function

    Full Text Available La lepra es una enfermedad milenaria, caracterizada como un problema de salud pública. Desarrollamos este estudio con el objetivo de conocer la percepción sobre su enfermedad de las personas en tratamiento para lepra. Se trata de un estudio con planteo cualitativo, desarrollado a través de un grupo focal en el mes de agosto de 2005 con ocho personas en tratamiento para lepra multibacilar en la Unidad Básica de Salud en Sobral-CE. Las declaraciones señalaron que la lepra es vista como una enfermedad mala, que trae tristeza, miedo, vergüenza y discriminación. Ser portador de lepra ocasionó sufrimiento psíquico y sentimientos de impotencia, hombres y mujeres tuvieron sus roles sociales amenazados. Sugerimos que se idealicen alternativas que atiendan no sólo la eliminación de la lepra como un problema de salud pública, sino también, como un rescate de la ciudadanía y del respeto por esas personas.

Enfrentamos a una sociedad que no ha sabido, ni querido, dar respuesta a las necesidades básicas de sus ciudadanos ya que su principal interés continúa siendo la acumulación del capital y el desarrollo de la ideología del mercado total. Esta historia no puede continuar porque ha llegado a su fin, al crear las condiciones infrahumanas que están destruyendo paulatinamente las vidas de un alto porcentaje de seres humanos. Para cambiar el curso de la Historia, es necesario una conciencia crítica del colectivo humano reprimido contra el status quo.

    1955, el Dr. Alvarado es separado de su cargo por la Revolución Libertadora, momento en que la Organización Panamericana de la Salud lo designa asesor regional y entre 1959 y 1964 lo nombran jefe del programa de erradicación de la malaria de la Organización Mundial de la Salud, en Ginebra, Suiza. A su regreso al país en 1966, organiza el Plan de Salud Rural, creando para ello la figura del "agente sanitario" y la "ronda sanitaria" anticipándose a conceptos que varios años después se plasmarían en la Atención Primaria de la Salud. El texto de Jauretche fue publicado originalmente en 1967 en el libro Los profetas del odio, por la editorial de Arturo Peña Lillo, editor de los grandes títulos del "pensamiento nacional" argentino.

    We discuss here compact binaries in which the orbital separation is small enough that mass is transferred from one star to the other. These systems are classified according to the nature of the primary: algols for ordinary stars, cataclysmic variables for white dwarfs, and X-ray binaries for black holes and neutron stars. These classes are often studied separately, even though the same physical processes occur in all objects; a global approach is most useful for understanding these objects and the physical processes. On discutera ici des binaires serrées dans lesquelles la séparation est suffisamment faible pour qu'il y ait échange de matière entre les deux étoiles. La classification de ces systèmes est liée à la nature de l'étoile accrétante: algols pour la séquence principale, variables cataclysmiques pour les naines blanches, et binaires X pour les étoiles à neutrons ou les trous noirs. Ces classes sont souvent étudiées de façon séparée, mais elles révèlent des processus physiques communs; la compréhension des objets et de la physique sous-jacente bénéficie d'une approche globale.

    Within the key project "Herschel M33 extended survey" (HerM33es), we are studying the physical and chemical processes driving star formation and galactic evolution in the nearby galaxy M33, combining the study of local conditions affecting individual star formation with properties only becoming apparent on global scales. Here, we present recent results obtained by the HerM33es team. Combining Spitzer and Herschel data ranging from 3.6um to 500um, along with HI, Halpha, and GALEX UV data, we have studied the dust at high spatial resolutions of 150pc, providing estimators of the total infrared (TIR) brightness and of the star formation rate. While the temperature of the warm dust at high brightness is driven by young massive stars, evolved stellar populations appear to drive the temperature of the cold dust. Plane-parallel models of photon dominated regions (PDRs) fail to reproduce fully the [CII], [OI], and CO maps obtained in a first spectroscopic study of one 2'x2' subregion of M33, located on the inner, nor...

Nos casos de parasitismo renal, observou-se acentuada atrofia do parênquima, transformando o rim numa bolsa fibrosa contendo o parasita em meio a exsudato necro-hemorrágico semilíquido. Foi observada hipertrofia renal compensatória contralateral em 5 casos. O ciclo evolutivo de D. renale é complexo e incompletamente entendido. Envolve um hospedeiro intermediário e hospedeiros paratênicos. A alta ocorrência da doença em cães de rua sugere que a infecção seja relacionada aos hábitos alimentares pouco seletivos desses animais.From 1978 to 1996, out of a total of 3,259 dogs necropsied, sixteen (0.49% were parasitized by Dioctophyma renale. Twelve of those (75% were stray dogs. Thirteen dogs (81.2% presented one or more specimens of D. renale in the right kidney. In three dogs (18.7%, the parasite was observed in the abdominal cavity. In those cases of renal parasitism, there was marked atrophy of the kidney which became a fibrous-walled bag within which the parasite was found imersed in a semiliquid necro-hemorrhagic exudate. In five cases, compensatory hypertrophy of the contralateral kidney was observed. The life cycle of D. renale is complex and not fully understood. It envolves intermediate and parathenic hosts. The high incidence of the disease in stray dog suggests that the infection is related to the poor selective feeding habits of this kind of dog.

    Full Text Available Diversos estudos têm demonstrado que, nas últimas décadas, mudanças nos hábitos alimentares vêm ocorrendo e que a proliferação de alimentos com diferentes finalidades passou a exigir do consumidor um alto nível de informação. Este artigo tem por objetivo principal investigar os fatores que influenciam a compra de alimentos infantis, observando especialmente os significados atribuídos por mães às informações nutricionais. Foram entrevistadas mães de diferentes níveis de escolaridade, renda, profissão e bairro de residência na cidade do Rio de Janeiro. O tratamento dos dados coletados ocorreu por meio da análise de conteúdo e, ao longo das entrevistas, foram questionados, por exemplo, quais fatores as mães entrevistadas consideravam importantes ao comprar alimentos para seus filhos e se tinham o costume de consultar as tabelas nutricionais dos alimentos no supermercado quando os estavam comprando. Adicionalmente, buscamos compreender o que, na perspectiva das mães, significam “alimentos pouco saudáveis” e qual conceito tinham sobre alimentos “nutritivos” e “saudáveis” - investigando se seriam sinônimos ou não. A partir de tais procedimentos, os resultados mostram que os três principais fatores que influenciam a compra de alimentos para os filhos são: i preço; ii marca; e iii a influência dos filhos. As interpretações a respeito das informações nutricionais puderam ser agrupadas em cinco categorias, quais sejam: 1 comprando besteira; 2 nutritivo versus saudável; 3 comer bem; 4 fatores importantes ao comprar alimentos para os filhos; e 5 informações nutricionais na intenção de compra.

    We present new far-ultraviolet spectra from the Cosmic Origins Spectrograph (HST/COS) of the BL Lac object 1ES1553+113 covering the wavelength range 1135-1795 A. The data show a smooth continuum with a wealth of narrow absorption features arising in the ISM and IGM. These features include 41 Lya absorbers at 00.6 for the strongest component of the absorber complex. Galaxy redshift surveys show a number of massive galaxies at approximately the same redshift as this absorption complex, suggesting that it arises in a large-scale galaxy filament. As one of the brightest extragalactic X-ray and gamma-ray sources, 1ES1553+113 is of great interest to the high-energy astrophysics community. With no intrinsic emission or absorption features, 1ES1553+113 has no direct redshift determination. We use intervening Lya absorbers to place a direct limit on the redshift: z_em>0.395 based on a confirmed Lya+OVI absorber and z_em>0.433 based on a single-line detection of Lya. COS/FUV data are only sensitive to Lya absorbers at ...

Diante da possibilidade de diferenças na sensibilidade e na reprodutibilidade das medidas obtidas nos traçados, o presente estudo teve como objetivo comparar os parâmetros eletrocardiográficos de cães, obtidos por dois sistemas. Foram avaliados dois diferentes softwares computadorizados, o Wincardio Micromed® (WIN e o modelo TEB ECGPC® (TEB. Quarenta e dois cães hígidos, de diferentes raças (Cocker Spaniel, Daschund, Labrador, Pinscher, Pit Bull Terrier Poodle, Schnauzer, Shit Tzu, Yorkshire e sem raça definida, machos e fêmeas e com idade entre 4 meses e 16 anos foram agrupados segundo o peso e examinados pelos dois sistemas. As medidas eletrocardiográficas dos diferentes traçados foram analisadas na derivação DII. Os resultados indicaram que o sistema TEB apresentou maior sensibilidade na obtenção das medidas de duração da onda P e do complexo QRS, enquanto o sistema WIN foi mais sensível para determinar as medidas de amplitude dos mesmos parâmetros. Os animais de maior porte (26-37kg apresentaram maior variância nas medidas de duração e amplitude de onda P e duração do complexo QRS em comparação aos cães de médio (14-25kg e pequeno (1-13kg porte. O achado de diferenças entre os sistemas testados deve ser levado em consideração ao se empregar os diversos equipamentos para diagnóstico por meio de ECG-C na rotina clínica, de modo a evitarem-se divergências na interpretação dos exames entre diferentes prestadores de serviços veterinários.

    Full Text Available El presente ensayo examina no solo como se forma el miedo moderno y su relación con la tragedia, sino las diversas formas culturales de vivirla respecto al futuro. Se antepone la figura de la personalidad heroica como una construcción moderna centrada en la necesidad de sentir placer por la pérdida. Esta tendencia lleva a las personas a sentirse únicas respecto a otras. Si el héroe es aquel que no se doblega ante el destino, también es un ser que lleva tras sí una historia de dolor y sufrimiento. Ahora bien, tanto los países de raigambre cultural latino como los germánicos han elaborado diferentes formas de vivir lo trágico; lo cierto es que el futuro, como construcción social, juega un rol importante en dichos procesos. Mien- tras para los anglosajones el futuro se mantiene como una entidad inmutable que no puede ser modificada, para los latinos el futuro se construye solo desde el presente. Abstract This essay aims to review how to form not only the modern man’s fear and its relationship with tragedy but also the way to live it according to the future. Heroic per- sonality is chosen as a modern figure focused on the need of pleasure feeling by the loss. This trend makes people to consider themselves unique related to others. If the hero is that one who does not bow down to the fate, it is also a human being who has a pain and suffering story behind him. Now, in those countries of deep seated Latin cultural roots such as German countries have established differ- ent ways of living. One thing is true, the future as social construction plays an important role in those processes. While English speaking countries the future is kept as immutable entity which can not be modified . For Latin people future is built only based on the present.

    Full Text Available Latinoamérica es una región caracterizada por grandes desigualdades de todo tipo. Estas son vistas como un subproducto del proceso de desarrollo, y, en este sentido, sería esperable que el desarrollo en una etapa avanzada se autocorrigiera. A través de las herramientas de la nueva economía institucional, este trabajo propone que los resultados distributivos de una sociedad no son consecuencias del mercado que eventualmente se autorregulará. La estructura institucional que determina el tipo de igualdad del que disfruta una sociedad es una elección de aquellos con el poder político para hacerlo. Ellos lo hacen conscientemente, calculando las consecuencias de sus actos. Se analizan las condiciones para tener ciertos tipos de instituciones económicas y políticas, y esto permite una idea más clara de la no aleatoriedad de la actual desigualdad económica. La explicación ilustrada aquí favorecerá la tesis de que las elecciones hechas por los individuos dentro de la élite política han creado el actual estado de problemas distributivos.

  7. Communication complexity and information complexity

    Science.gov (United States)

    Pankratov, Denis

    Information complexity enables the use of information-theoretic tools in communication complexity theory. Prior to the results presented in this thesis, information complexity was mainly used for proving lower bounds and direct-sum theorems in the setting of communication complexity. We present three results that demonstrate new connections between information complexity and communication complexity. In the first contribution we thoroughly study the information complexity of the smallest nontrivial two-party function: the AND function. While computing the communication complexity of AND is trivial, computing its exact information complexity presents a major technical challenge. In overcoming this challenge, we reveal that information complexity gives rise to rich geometrical structures. Our analysis of information complexity relies on new analytic techniques and new characterizations of communication protocols. We also uncover a connection of information complexity to the theory of elliptic partial differential equations. Once we compute the exact information complexity of AND, we can compute exact communication complexity of several related functions on n-bit inputs with some additional technical work. Previous combinatorial and algebraic techniques could only prove bounds of the form theta( n). Interestingly, this level of precision is typical in the area of information theory, so our result demonstrates that this meta-property of precise bounds carries over to information complexity and in certain cases even to communication complexity. Our result does not only strengthen the lower bound on communication complexity of disjointness by making it more exact, but it also shows that information complexity provides the exact upper bound on communication complexity. In fact, this result is more general and applies to a whole class of communication problems. In the second contribution, we use self-reduction methods to prove strong lower bounds on the information

    Full Text Available En este trabajo se analiza el artículo titulado "El alivio del dolor como un derecho humano", escrito por F. Brennan y M. Cousins, en donde los autores proclaman la formulación de un novedoso derecho fundamental y revisan diversos instrumentos internacionales de Derechos Humanos, para sustentar el argumento de que el paciente debe ser protegido contra el insuficiente tratamiento del dolor. Diversos autores y organizaciones han denunciado las causas, debidas a diversos factores, por las cuales el dolor no es tratado en toda su extensión. Los factores normativos estriban en la autorización y/o prohibición de la distribución, consumo, uso y comercialización de fármacos, por parte de las agencias gubernamentales. Los factores económicos son multicausales puesto que se relacionan directamente con el acceso a servicios de salud y a medicamentos. Se identifica como un serio problema de salud pública, el que no se destinen suficientes recursos para la implementación de unidades para tratamiento del dolor crónico o temporal o para la investigación relativa al tema. La falta de educación y actualización de los profesionales de salud es otro problema importante. Dentro de las causas sociales se encuentran entre otras, la desigualdad en el acceso a los servicios de salud, la pobreza, la falta de cobertura médica y la discriminación hacia ciertos grupos sociales. En el texto se hace un sucinto recorrido por los principales instrumentos internacionales de Derechos Humanos. Se retoman los instrumentos examinados por Brennan y Cousins, con la aportación de agregar documentos regionales del Sistema Interamericano de Derechos Humanos. Para los Estados Miembros de la Organización de los Estados Americanos (OEA, que padecen la problemática propia de los países en vías de desarrollo: muchas necesidades, alta densidad de población y escasez de recursos, se torna urgente plantearse el Derecho a la Salud bajo nuevas perspectivas.

    Full Text Available El uso generalizado de la expresión “justicia global” indica un cambio en la estructura del discurso moral. Tradicionalmente, las relaciones internacionales se consideraban como algo distinto de la justicia nacional. Antes se centraban en las interacciones entre los Estados, y luego se consideró el diseño del orden institucional nacional a la luz de sus efectos sobre los ciudadanos. Ese análisis moral institucional se empieza a aplicar a los arreglos institucionales supranacionales, hoy más influyentes e importantes en la vida de las personas. La perspectiva tradicional sugería acuerdos justos entre los Estados. La nueva perspectiva muestra que el orden institucional global es injusto pues enriquece a las élites de los países ricos y pobres, y perpetúa la opresión y el empobrecimiento de las mayorías.

    1995-08-01

    Environmental, Safety and Health (ES&H) issues became an important design consideration during the development of the W89 warhead for the SRAM 11 (Short-Range Attack Missile) missile. An action plan was developed to handle these issues at all the production agencies and at both the system and the component level. The main thrust was in the area of solvent substitution, in particular for solder flux removal. The cleaner d-limonene followed by an isopropyl alcohol rinse was selected for applications were the traditional cleaners were 1,1,1 trichloroethane or trichloroethylene. Compatibility testing rather than efficacy testing dominated the development effort. In addition to other solvent substitution applications, organic materials that were free of toluene diisocynate (TDI), and methylene dianiline (MDA) were explored for use in the W89.

    Full Text Available A cross-sectional survey of agricultural areas, combined with routinely monitored mosquito larval information, was conducted in urban Dar es Salaam, Tanzania, to investigate how agricultural and geographical features may influence the presence of Anopheles larvae. Data were integrated into a geographical information systems framework, and predictors of the presence of Anopheles larvae in farming areas were assessed using multivariate logistic regression with independent random effects. It was found that more than 5% of the study area (total size 16.8 km2 was used for farming in backyard gardens and larger open spaces. The proportion of habitats containing Anopheles larvae was 1.7 times higher in agricultural areas compared to other areas (95% confidence interval = 1.56-1.92. Significant geographic predictors of the presence of Anopheles larvae in gardens included location in lowland areas, proximity to river, and relatively impermeable soils. Agriculture-related predictors comprised specific seedbed types, mid-sized gardens, irrigation by wells, as well as cultivation of sugar cane or leafy vegetables. Negative predictors included small garden size, irrigation by tap water, rainfed production and cultivation of leguminous crops or fruit trees. Although there was an increased chance of finding Anopheles larvae in agricultural sites, it was found that breeding sites originated by urban agriculture account for less than a fifth of all breeding sites of malaria vectors in Dar es Salaam. It is suggested that strategies comprising an integrated malaria control effort in malaria-endemic African cities include participatory involvement of farmers by planting shade trees near larval habitats.

    2004-12-01

    Full Text Available This article discusses some women' s movements in Morocco. It intends to demonstrate that the usual model that is used to explain women' s movements in the Arab World is not valid This model considers two kinds of women's movements: on the one hand, Western feminist movements, occidentalists, and on the other, Islamist movements, which are theoretically more authentic but also more repressive. Through the analysis of the positions adopted by Islamist and Feminist groups toward juridical changes of Mudawana, as well as the constructions of "womanhood" in these groups, the article shows how this dichotomous model oversimplifies the explanation of these processes. Furthermore, the use of this model in the research is not neutral. It has political consequences, such as the primitivization of the other. Ethnography makes possible other approaches to the topic and allows us to build a more nuanced interpretation.

    El presente artículo analiza los movimientos de mujeres en Marruecos, confrontándolos a lo que viene siendo el esquema habitual de tratamiento: movimientos feministas, de tipo occidental, frente a movimientos islamistas, más "auténticos", pero de carácter represivo. A través de un análisis de los cambios jurídicos en Marruecos, así como de los modelos de "mujer" que defiende cada movimiento, el artículo muestra que el esquema explicativo de la dicotomía de islamismo frente a feminismo para explicar la cuestión no es válido. Su uso no es neutro, y en ocasiones puede tener consecuencias perversas, que primitivizan al "otro". En cambio, el estudio de estos movimientos en el contexto social y político marroquí, puede arrojar luz sobre un problema que estimula, en ocasiones, y bloquea, en otras, el cambio en Marruecos.

    Full Text Available OBJETIVO: Estudar os efeitos da associação do adesivo cirúrgico de fibrina à técnica operatória da invaginação submucosa, em anastomoses esofagianas. MÉTODO: Trinta e dois cães submetidos à anastomose esôfago-esofágica foram alocados em dois grupos: I com sutura em doze pontos e II com sutura em quatro pontos e vedação com adesivo de fibrina. Os animais foram avaliados no sétimo e décimo-quarto dias de pós-operatório. Foram analisados: a evolução ponderal, o índice de estenose, a incidência de deiscências e fístulas, a presença de secreções na tela subcutânea, a presença de líquido intersticial, matriz protêica, celularidade, fibroblastos, fibras de colágeno e concentração de hidroxiprolina. RESULTADOS: O índice de estenose foi menor para os animais do grupo I no sétimo dia de observação. Nos animais do grupo II a incidência de deiscências, secreção serosa e purulenta foram signitivamente maiores aos sete e quatorze dias, enquanto a presença de fístulas foi maior no sétimo dia. Quanto à concentração tecidual de hidroxiprolina não houve diferença estatística entre os grupos. Os fibroblastos e fibras de colágeno tiveram presença mais acentuada no grupo II no décimo-quarto dia. Ocorreram quatro óbitos em animais do grupo II. CONCLUSÕES: A anastomose por invaginação submucosa-mucosa com vedação com adesivo de fibrina apresentou piores resultados que a anastomose convencional de doze pontos circunferenciais.

    2013-06-01

    In this paper, we present a novel visualization technique for assisting the observation and analysis of algorithmic complexity. In comparison with conventional line graphs, this new technique is not sensitive to the units of measurement, allowing multivariate data series of different physical qualities (e.g., time, space and energy) to be juxtaposed together conveniently and consistently. It supports multivariate visualization as well as uncertainty visualization. It enables users to focus on algorithm categorization by complexity classes, while reducing visual impact caused by constants and algorithmic components that are insignificant to complexity analysis. It provides an effective means for observing the algorithmic complexity of programs with a mixture of algorithms and black-box software through visualization. Through two case studies, we demonstrate the effectiveness of complexity plots in complexity analysis in research, education and application. © 2013 The Author(s) Computer Graphics Forum © 2013 The Eurographics Association and Blackwell Publishing Ltd.

    Full Text Available RESUMEN: La autoestima es uno de los conceptos psicológicos más complejos y uno de los más difíciles de precisar, a pesar de ser un factor que siempre ha estado presente en cualquier intento de explicación del comportamiento humano normal y patológico. Describir adecuadamente qué es la autoestima, requiere abordar previamente algunos aspectos que han influido en la falta de precisión de este concepto. En este sentido es necesario puntualizar que autoconcepto y autoestima no son términos intercambiables aunque ambos se impliquen, que la autoestima no es un factor unitario sino multidimensional, que la autoestima no sólo incluye los aspectos positivos y más valorables del sujeto, sino también aspectos menos valorables o las limitaciones y por último, que la autoestima no es autoafirmación incondicional ante los demás, sino autoafirmación respetando la individualidad de los otros. Se puede definir la autoestima como «la valoración positiva o negativa que el sujeto hace de su autoconcepto, valoración que se acompaña de sentimientos de valía personal y auto aceptación». La autoestima, así entendida, influye y se expresa a través del comportamiento del sujeto en todas sus dimensiones y manifestaciones, tales como autoaceptación, afrontamiento, aceptación de los demás e interacciones sociales, entre otras.ABSTRACT: Self-esteem is one of the most complex psychological concepts an one of the most difficult ones to define, despite the fact that it is a factor that has always been present in any attempt to explain the normal and pathological human behavior.

    2001-01-01

    The world of artificial systems is reaching complexity levels that es­ cape human understanding. Surface traffic, electricity distribution, air­ planes, mobile communications, etc. , are examples that demonstrate that we are running into problems that are beyond classical scientific or engi­ neering knowledge. There is an ongoing world-wide effort to understand these systems and develop models that can capture its behavior. The reason for this work is clear, if our lack of understanding deepens, we will lose our capability to control these systems and make they behave as we want. Researchers from many different fields are trying to understand and develop theories for complex man-made systems. This book presents re­ search from the perspective of control and systems theory. The book has grown out of activities in the research program Control of Complex Systems (COSY).

    Full Text Available Las ciencias sociales y las ciencias de la evolución elaboraron nociones de la cultura, cuyas particularidades respectivas estimularon uno de los debates mas controvertidos de la antropología. Vista por las ciencias sociales, la noción de cultura estuvo en un principio inspirada por la noción de progreso y por la doctrina de la evolución, antes que la naturaleza biológica del hombre llegue a estar disociada de sus realizaciones culturales. Sin embargo permanecen los universales, esas marcas permanentes que transcienden los particularismos culturales que los antropólogos buscan desde los años treinta y que los reencuentra la antropología cognitiva actual bajo otras formas. Ellos no dejan de evocar las sujeciones que implica la tesis de una base genética de los comportamientos. L'etologia constituida como disciplina alrededor de los años 30, habiendo analizado el mecanismo de los comportamientos de comunicación codificados, lanzo las bases de una genética de los "instintos" y se dedico a reconstruir su filigénesis y su ontogénesis. De estas investigaciones nacieron los fundamentos de una teoría de la cultura que toma prestado los mecanismos evolutivos del neo-darwinismo. Esta teoría, la sociobióloga, luego de amplias investigaciones en el dominio de los comportamientos sociales animales, extrapola esos principios y sus teoremas al caso de la evolución humana e interroga a los antropólogos sobre aquello que para ellos es lo mas especifico: los comportamientos culturales humanos. Podemos extrapolar los comportamientos animales a los comportamientos humanos? Investigaciones mas profundas sobre ciertos comportamientos de base como los comportamientos reproductivos, parecen indicar respuestas que varían según las culturas y según los estratos sociales. En todo caso, revocan la noción de comportamientos universales y si no invalidan que existe una especie de "raíz" animal a numerosos comportamientos elementales, estas indican

    Full Text Available Este artículo trata de recuperar un diálogo crítico entre la política y el trabajo social. Se argumenta que la política es una dimensión de la identidad del trabajo social de la que no podemos sustraernos. De ahí que la política y el trabajo social están doblemente ligados porque, por un lado, el ejercicio del poder político corresponde a todo ciudadano en el cuidado de la polis; por otro, el trabajo social está estrechamente vinculado a la política social por medio de su objeto de estudio. Para construir nuestros argumentos partimos de un diagnóstico de la realidad social y profesional que se sostiene en determinados supuestos que configuran esta relación específica. Pretendemos con todo ello aportar elementos de análisis que ayuden, no sólo a comprender, sino a contribuir con nuestras respuestas, información y participación, a la política, tanto como profesionales del trabajo social como por ser ciudadanos de la sociedad civil.  The intention of this article is to try to recover a critical dialog between the politics and the social work. In this paper it argued that the politics is a dimension of the identity of the social work of which we cannot avoid. In this way, the politics and the social work, are doubly tied. On the one hand, the political power exercise corresponds to every citizen of the polis. And, on the other hand, the social work is narrowly tied to the social politics by means of its object of study. Our arguments it’s construct from a diagnosis of the social reality and professional that is held in this specific relationship. We claim to contribute with elements of analyses that help, not only to understand, but also answering politically as professionals of the social work and as citizen in the society.

  20. [es] Los conocimientos en trabajo social: elogio del eclecticismo

    2010-06-01

    Full Text Available La ciencia está en el origen del trabajo social. En efecto, el objetivo que perseguía Mary Richmond al conceptualizar la disciplina de trabajo social consistía en reemplazar las creencias religiosas por un enfoque racional. Así pues, el conocimiento científico se inscribe en el corazón del trabajo social desde el principio. Dicho esto, las grandes teorías son menos útiles en la práctica de una profesión cuya finalidad es ayudar a las personas que viven las situaciones más diversas. Esta es la razón por la cual el trabajo social se construye a partir de una base ecléctica: el trabajador social eficaz toma de un vasto conjunto de nociones, en apariencia dispares, aquellas que mejor se adaptan a la situación. Ahora bien, ¿cómo enseñar este conocimiento práctico a los estudiantes de trabajo social? Este artículo trata de estas cuestiones y propone algunas pistas de reflexión. Science is closely related to social work, from its very origin. In fact, with the conceptualization of social work, Mary Richmond’s objective was to replace religious beliefs by a more rational approach. Thus, right from its beginning, the scientific knowledge was at the core of social work. This being said, grand theories are less appropriate to the practice of social work because this profession deals with persons living in particular situations. That is why social work is built upon an eclectic basis : social worker has to draw from a vast array of notions and theories to borrow bits and pieces which will help to explain and attenuate problem experienced by persons. Now, this practical knowledge can be taught to students in social work? This article deals with these questions and proposes some reflections.

  1. Engaging complexity

    Full Text Available In this article, I discuss studies in complexity and its epistemological implications for systematic and practical theology. I argue that engagement with complexity does not necessarily assurea non-reductionist approach. However, if complexity is engaged transversally, it becomes possible to transcend reductionist approaches. Moreover, systematic and practical the ologians can draw on complexity in developing new ways of understanding and, therefore, new ways of describing the focus, epistemic scope and heuristic structures of systematic and practical theology. Firstly, Edgar Morin draws a distinction between restricted and general complexity based on the epistemology drawn upon in studies in complexity. Moving away from foundationalist approaches to epistemology, Morin argues for a paradigm of systems. Secondly,I discuss Kees van Kooten Niekerk�s distinction between epistemology, methodology andontology in studies in complexity and offer an example of a theological argument that drawson complexity. Thirdly, I argue for the importance of transversality in engaging complexity by drawing on the work of Wentzel van Huyssteen and Paul Cilliers. In conclusion, I argue that theologians have to be conscious of the epistemic foundations of each study in complexity, and these studies illuminate the heart of Reformed theology.Intradisciplinary and/or interdisciplinary implications: Therefore, this article has both intradisciplinary and interdisciplinary implications. When theologians engage studies incomplexity, the epistemological roots of these studies need to be considered seeing thatresearchers in complexity draw on different epistemologies. Drawing on transversality wouldenhance such considerations. Furthermore, Edgar Morin�s and Paul Cilliers� approach tocomplexity will inform practical and theoretical considerations in church polity and unity.

    Odontomas are hamartomatous lesions or malformations composed of mature enamel, dentin, and pulp. They may be compound or complex, depending on the extent of morphodifferentiation or their resemblance to normal teeth. The etiology of odontoma is unknown, although several theories have been proposed. This article describes a case of a large infected complex odontoma in the residual mandibular ridge, resulting in considerable mandibular expansion.

    In the context of overseeing the quality of data, and as a result of the inherent complexity of projects such as CMIP5/6, it is a mandatory task to keep track of the status of datasets and the version evolution they sustain in their life-cycle. The ESdoc-errata project aims to keep track of the issues affecting specific versions of datasets/files. It enables users to resolve the history tree of each dataset/file enabling a better choice of the data used in their work based on the data status. The ES-doc-errata project has been designed and built on top of the Parent-IDentifiers handle service that will be deployed in the next iteration of the CMIP project, by ensuring maximum usability of ESGF ecosystem and encapsulated in the ES-doc structure. Consuming PIDs from handle service is guided by a specifically built algorithm that extracts meta-data regarding the issues that may or may not affect the quality of datasets/files and cause newer version to be published replacing older deprecated versions. This algorithm is able to deduce the nature of the flaws to the file granularity, that is of high value to the end-user. This new platform has been designed keeping in mind usability by end-users specialized in the data publishing process or other scientists requiring feedback on reliability of data required for their work. To this end, a specific set of rules and a code of conduct has been defined. A validation process ensures the quality of this newly introduced errata meta-data , an authentication safe-guard was implemented to prevent tampering with the archived data, and a wide variety of tools were put at users disposal to interact safely with the platform including a command-line client and a dedicated front-end.

  7. GC-rich sequence elements recruit PRC2 in mammalian ES cells.

    Directory of Open Access Journals (Sweden)

    2010-12-01

    Full Text Available Polycomb proteins are epigenetic regulators that localize to developmental loci in the early embryo where they mediate lineage-specific gene repression. In Drosophila, these repressors are recruited to sequence elements by DNA binding proteins associated with Polycomb repressive complex 2 (PRC2. However, the sequences that recruit PRC2 in mammalian cells have remained obscure. To address this, we integrated a series of engineered bacterial artificial chromosomes into embryonic stem (ES cells and examined their chromatin. We found that a 44 kb region corresponding to the Zfpm2 locus initiates de novo recruitment of PRC2. We then pinpointed a CpG island within this locus as both necessary and sufficient for PRC2 recruitment. Based on this causal demonstration and prior genomic analyses, we hypothesized that large GC-rich elements depleted of activating transcription factor motifs mediate PRC2 recruitment in mammals. We validated this model in two ways. First, we showed that a constitutively active CpG island is able to recruit PRC2 after excision of a cluster of activating motifs. Second, we showed that two 1 kb sequence intervals from the Escherichia coli genome with GC-contents comparable to a mammalian CpG island are both capable of recruiting PRC2 when integrated into the ES cell genome. Our findings demonstrate a causal role for GC-rich sequences in PRC2 recruitment and implicate a specific subset of CpG islands depleted of activating motifs as instrumental for the initial localization of this key regulator in mammalian genomes.

    2014-06-01

    Full Text Available Understading the hydrodynamic behavior and suspended particulated matter (SPM transport are of great importance in port regions such as Vitória Harbor, which is located at Vitória Bay, Vitória – ES, Brazil. Vitória Bay is an estuary that has not been systematically assessed through a temporal analysis in order to identify its hydrodynamics characteristics and SPM exchange. This study aims to investigate salt and suspended particulate matter flux at the estuarine mouth of Vitória Bay by understanding the temporal variation of salinity, temperature and tidal currents within the water column and at the channel crosssection. Results showed that the estuarine mouth tended to present partial stratification periods during neap tides and little stratification in spring tides. The circulation pattern was mainly influenced by the tide, with little influence from river discharge. With regard to the SPM, the mouth of the estuary tended to show low concentrations, with the highest values occurring during the dry season. A close relationship between momentary discharge, SPM and salt fluxes was observed. Despite all the data was collected at the mouth of the estuary, the system showed an importation trend of salt in all cycles and SPM importation for three of the four studied tidal cycles. Thus, Vitoria Bay is not exporting SPM to the adjacent inner shelf.

    Full Text Available Implantierbare Kardioverter-Defibrillatoren (ICDs haben sich als Standardtherapie zur primären und sekundären Prävention des plötzlichen Herztodes für Patienten mit eingeschränkter Linksventrikelfunktion in breitem Umfang etabliert. Mit zunehmendem Lebensalter bestimmen jedoch häufig relevante Komorbiditäten den klinischen Verlauf, sodass sich dadurch der Überlebensvorteil durch den ICD relativieren kann. Dieser Umstand wirft sowohl ethische als auch rechtliche Fragen auf, vor allem, wenn es um den Gerätewechsel bei Batterieerschöpfung oder um die Deaktivierung der ICD-Funktion in einem fortgeschrittenen Krankheitsstadium geht. Der Informationsstand von Patienten bezüglich der Möglichkeit zur ICD-Deaktivierung bei aussichtsloser Erkrankung hängt in hohem Maße von einer frühzeitigen Aufklärung durch das betreuende Fachpersonal ab, welches aber aus diversen Gründen die aktive Kommunikation zu selten aufgreift. Aufgrund der zunehmenden Komplexität im Management von Rhythmuspatienten werden daher aktuell von den Fachgesellschaften nicht nur Richtlinien für die Geräteimplantation, sondern auch für die Gerätedeaktivierung bei absehbarem Lebensende beziehungsweise Patientenwunsch publiziert. Der folgende Artikel beleuchtet diese Thematik aus unterschiedlichen Gesichtspunkten und soll als Hilfestellung für eine multidisziplinäre Entscheidung im Konsens mit dem Patienten bzw. dessen Angehörigen oder gesetzlichen Vertretern dienen.

    In this letter, we compare optical light curves of two SN2002es-like Type Ia supernovae, iPTF14atg and iPTF14dpk, from the intermediate Palomar Transient Factory. Although the two light curves resemble each other around and after maximum, they show distinct early-phase rise behavior in the $\\textit{r}$-band. On the one hand, iPTF14atg revealed a slow and steady rise which lasted for 22 days with a mean rise rate of $0.2\\sim0.3\\,\\textrm{mag}\\,\\textrm{day}^{-1}$, before it reached the $R$-band peak ($-18.05\\,$mag). On the other hand, iPTF14dpk rose rapidly to $-17\\,$mag within a day of discovery with a rise rate $>1.8\\,\\textrm{mag}\\,\\textrm{day}^{-1}$, and then rose slowly to its peak ($-18.19\\,$mag) with a rise rate similar to iPTF14atg. The apparent total rise time of iPTF14dpk is therefore only 16 days. We show that emission from iPTF14atg before $-17\\,$days with respect to its maximum can be entirely attributed to radiation produced by collision between the SN and its companion star. Such emission is absent...

    2001-01-01

    Smad5 is an intracellular transducer of TGF-b signals. Targeteddisruption of murine Smad5 gene resulted in embryonic lethal. To study the function of Smad5 in organgenesis, we generated Smad5 double knockout ES cells by homologous recombination. We deleted the neo gene of the Smad5 targeted ES cells using Cre-LoxP system. Smad5 double knockout ES cells were obtained by transfecting the targeted ES cells using the same targeting construct. The results of chimeric study showed that Smad5 might play an important role during the development of heart and neural tube. Smad5 double knockout ES cells formed teratoma when injected subcutaneously into nude mice. They differentiated into several types of cells, including neural cells, muscle cells, chondrocytes, endothelial cells and glandaceous cells. Smad5 double knockout ES cells are useful for studying the function of Smad5 mediated TGF- b during the organgenesis and the in vitro differentiation of ES cells.

    Full Text Available Gregorio Marañón wrote relatively little about emotion. Nevertheless, he considered emotion to be “one of the most interesting problems of human life.” This article describes the basic brain processes of emotion that motivates living beings to follow patterns of behaviour whose ultimate meaning is the survival of the individual and the species. A description is given here of the emotional processing of sensory information. It is noted that any process of conscious learning and memory is always emotionally coloured. Finally, one of the main conclusions of this article is that there is no rational thought without a previous emotional process in the brain. There is no reason without emotion. This is a conclusion that would probably have amazed Professor Marañón.El Dr. Gregorio Marañón no escribió mucho sobre la emoción. Pero sí es cierto que consideró que se trataba de “uno de los problemas más interesantes de la vida humana”. En este artículo se describen los procesos cerebrales básicos de la emoción que nos alertan y motivan hacia la realización de conductas en cuyo significado último se encuentra la supervivencia del individuo y de la especie. Se describe el procesamiento emocional de la información sensorial. Se señala que todo proceso de aprendizaje y memoria consciente siempre viene coloreado emocionalmente. Y se destaca que el profesor Marañón posiblemente mostraría asombro ante una de las principales conclusiones de este artículo en las que se indica que no hay pensamiento sin una emoción previa que lo alimente. Que no hay razón sin emoción.

    Full Text Available El concepto de un objeto geométrico está mediado, entre otras cosas, por las experiencias que se tienen con él. La hipótesis de este estudio es que realizar un proceso de conceptualización de un objeto, con el uso de un entorno de geometría dinámica, ayuda no solo a formular, formalizar y estructurar definiciones jerárquicas y económicas de los objetos, sino además a hacer obstensible la definición con la que los estudiantes trabajan en un contexto de actividad demostrativa. Para sustentar la hipótesis se analizaron sesiones de clases de dos espacios académicos consecutivos de un programa de formación inicial de profesores, y un cuestionario aplicado a los estudiantes. Se buscaron así evidencias que permitieran, sustentado en el marco teórico que orientó el estudio, determinar el impacto de trabajar en un entorno donde se usa un software de geometría dinámica como mediador para el aprendizaje. Los resultados permitieron establecer, entre otras cosas, que el trabajo realizado con geometría dinámica debe ir acompañado de acciones intencionadas orientadas por la docente. Se evidenció que se continúan presentando, aún después de usar geometría dinámica, varias dificultades respecto al concepto del objeto geométrico cuadrado, como el predominio de los aspectos figurales sobre los conceptuales, y la dificultad para modificar las definiciones personales del concepto y las imágenes conceptuales, que surgen cuando los estudiantes realizan actividad demostrativa.

Los datos provienen de la Encuesta Nacional por Muestra de Domicilios (PNAD y se analizaron en el cultivo que comprende los años 2001 y 2008. Estadísticas clave mostraron el aumento de la participación femenina en el mercado laboral con una mayor incidencia en la población económicamente activa (PEA en el año que se examina. Por otra parte, la tasa de desempleo femenino se redujo en casi todas las áreas metropolitanas de Brasil, mediante el aumento de la tasa de ocupación. Sin embargo, son una minoría en el mercado laboral formal, en comparación con los hombres, teniendo en cuenta el alto porcentaje de empleados sin registrar. Además, las minorías siguen en puestos de trabajo con más proyección social, a pesar de un contexto de aumento de la participación relativa en los últimos años. Ya en trabajos de proyección social más baja son más en todas las áreas metropolitanas. Por lo tanto, tenemos, por supuesto, la selectividad en el mercado de trabajo en zonas urbanas del Brasil, teniendo en cuenta especialmente la ocupación por sexo. En tal escenario, es más adecuado proponer políticas confirmación del trabajo de las mujeres.

    Full Text Available RESUMEN: En este trabajo se pretende repensar algunos puntos claves del debate reciente sobre la profesionalización docente, analizando en concreto las tres cuestiones siguientes: ¿Qué es una profesión? ¿Cuáles son los rasgos diferenciales de la misma? ¿En qué medida podemos afirmar que el profesorado cumple los requisitos convencionales de las profesiones? Aunque hay un acuerdo generalizado acerca de la necesidad de mejorar el status profesional de la enseñanza, no hay coincidencia en la forma de conseguirlo. Para entender las diferentes posiciones, se analizan, además, los conceptos de profesionalismo y profesionalización, y se destaca la importancia de la formación como un proceso de desarrollo personal y profesional. Por último se tratan aspectos relacionados con la salud laboral y las enfermedades profesionales.ABSTRACT: This article proposes to rethink some of the key issues of the recent debate about the teaching profession, through the analysis of three specific aspects: What is a profession? What are its distinctive features? To what extent can we say that teachers are satisfying the demands of the profession? Although there is a general agreement about the need to improve the professional quality of teaching, there doesn't seen to be a way to achieve it. In order to understand the different points of view, there will also be an analysis of the notions of professionalism and professionalization, with an emphasis on the importance of formation as professional and personal development process. To conclude, the issues of laboral health and professional illnesses will be dealt with.

    The sensors described here have been studied in our laboratory. The industrial development of some of them is now in progress. They exploit the properties of elastic waves propagating, according to a chosen mode, in a plate or in a cylinder. The sensors comprising a plate are a graphic tablet, a map coordinate resolver, a touch screen and a liquid presence detector. The sensors comprising a cylinder are a liquid presence detector and a liquid level sensor. Before describing these devices, we comment on the dispersion curves and express the attenuation factor for guided waves in presence of a liquid. Les capteurs présentés dont certains sont en cours de développement industriel ont été étudiés dans notre laboratoire. Ils exploitent les propriétés d'ondes élastiques se propageant, suivant un mode choisi, dans une plaque ou un cylindre. Les capteurs comprenant une plaque sont une tablette de saisie de graphiques, un coordinomètre, un écran tactile et un détecteur de la présence d'un liquide, les capteurs comprenant un cylindre ou un tube sont un détecteur de présence et un jaugeur du niveau d'un liquide. Avant de les décrire, nous commentons les courbes de dispersion et calculons le coefficient d'atténuation de ces ondes guidées en présence d'un liquide.

  9. Dynamic transcription programs during ES cell differentiation towards mesoderm in serum versus serum-freeBMP4 culture

    Full Text Available Abstract Background Expression profiling of embryonic stem (ES cell differentiation in the presence of serum has been performed previously. It remains unclear if transcriptional activation is dependent on complex growth factor mixtures in serum or whether this process is intrinsic to ES cells once the stem cell program has been inactivated. The aims of this study were to determine the transcriptional programs associated with the stem cell state and to characterize mesoderm differentiation between serum and serum-free culture. Results ES cells were differentiated as embryoid bodies in 10% FBS or serum-free media containing BMP4 (2 ng/ml, and expression profiled using 47 K Illumina(R Sentrix arrays. Statistical methods were employed to define gene sets characteristic of stem cell, epiblast and primitive streak programs. Although the initial differentiation profile was similar between the two culture conditions, cardiac gene expression was inhibited in serum whereas blood gene expression was enhanced. Also, expression of many members of the Kruppel-like factor (KLF family of transcription factors changed dramatically during the first few days of differentiation. KLF2 and KLF4 co-localized with OCT4 in a sub-nuclear compartment of ES cells, dynamic changes in KLF-DNA binding activities occurred upon differentiation, and strong bio-informatic evidence for direct regulation of many stem cell genes by KLFs was found. Conclusion Down regulation of stem cell genes and activation of epiblast/primitive streak genes is similar in serum and defined media, but subsequent mesoderm differentiation is strongly influenced by the composition of the media. In addition, KLF family members are likely to be important regulators of many stem cell genes.

    Full Text Available Hay quienes piensan que el objetivo principal de la mercadotecnia es vender más, o bien, colocar productos y distribuirlos, o que es una herramienta para atraer a los clientes o inclusive para manipularlos. El objetivo del presente ensayo es reflexionar sobre el objetivo principal de esta disciplina, la cual es realmente una filosofía de vida empresarial. Se concluye que dicho objetivo es fomentar el intercambio voluntario entre dos o más partes que tienen algo que interesa a unos y a otros entre sí. El resultado de dicho intercambio, el cual es la clave en el proceso de la mercadotecnia, es lograr más ventas a través de satisfacer a los clientes y conseguir su lealtad mediante la identificación de sus necesidades y deseos, conjuntándolos con productos y servicios de calidad. Otra conclusión es que la satisfacción del cliente y las ventas, que para la empresa son objetivos, para la mercadotecnia son resultados del correcto fomento del intercambio voluntario en la gestión de negocios, el cual es su objetivo como disciplina en sí. Por otra parte, tampoco puede decirse que el mercadólogo sea un creador de necesidades ya que su papel es detectarlas y proponer los satisfactores para las mismas.

    Our society nowadays is governed by complex networks, examples being the power grids, telecommunication networks, biological networks, and social networks. It has become of paramount importance to understand and characterize the dynamic events (e.g. failures) that might happen in these complex networks. For this reason, in this paper, we propose two measures to evaluate the vulnerability of complex networks in two different dynamic multiple failure scenarios: epidemic-like and cascading failures. Firstly, we present \\emph{epidemic survivability} ($ES$), a new network measure that describes the vulnerability of each node of a network under a specific epidemic intensity. Secondly, we propose \\emph{cascading survivability} ($CS$), which characterizes how potentially injurious a node is according to a cascading failure scenario. Then, we show that by using the distribution of values obtained from $ES$ and $CS$ it is possible to describe the vulnerability of a given network. We consider a set of 17 different compl...

El contexto digital impone velocidad, plasticidad, inmediatez y visibilidad a las narraciones. Los relatos circulan por diversos soportes, mutando sentidos, provocando que el conocimiento, el arte, las informaciones sean apropiadas y resignificadas. Mientras tanto hay resistencias, instituciones que sostienen que las formas tradicionales deben continuar dada su validez comprobada. Así se da una yuxtaposición de intereses y tensiones entre prácticas y sentidos. Observaremos esta tensión para comprenderla, para ver y definir eso que culmina mientras algo nuevo, que aún no tiene una estructura precisa, comienza a surgir ¿Será que estas innovadoras alternativas tecnológicas facilitan la democratización del conocimiento, entendiendo que el uso de las tecnologías responde a fundamentos políticos y pedagógicos? A partir de una perspectiva comunicacional analizaremos la complejidad de la producción social de conocimiento, el uso de las tecnologías, los vínculos entre los sujetos partícipes en estos procesos y las múltiples disputas en juego. Detallar las coordenadas de espacio y tiempo permiten situar la producción y garantiza la comprensión del proceso. Una de las primeras cosas que aprendemos en las aulas de la universidad pública es que el conocimiento se sitúa históricamente. Desde la primera pregunta que se antepone a cualquier investigación comprendemos que las hipótesis son producto de un pensamiento crítico referido a constricciones económicas, políticas y socioculturales de la propia sociedad en la que se vive y se formulan dichas hipótesis. Las innovaciones en formatos y soportes de comunicación exigen resituar y adecuar las estrategias.

    The guiding principle of this presentation of ``Classical Complex Analysis'' is to proceed as quickly as possible to the central results while using a small number of notions and concepts from other fields. Thus the prerequisites for understanding this book are minimal; only elementary facts of calculus and algebra are required. The first four chapters cover the essential core of complex analysis: - differentiation in C (including elementary facts about conformal mappings) - integration in C (including complex line integrals, Cauchy's Integral Theorem, and the Integral Formulas) - sequences and series of analytic functions, (isolated) singularities, Laurent series, calculus of residues - construction of analytic functions: the gamma function, Weierstrass' Factorization Theorem, Mittag-Leffler Partial Fraction Decomposition, and -as a particular highlight- the Riemann Mapping Theorem, which characterizes the simply connected domains in C. Further topics included are: - the theory of elliptic functions based on...

As ganglionites e periganglionites do plexo de Auerbach variaram de discretas a moderadas, induzindo lesões neuronais significativas, principalmente em dois animais. Os gânglios do plexo de Meissner foram observados em pequeno número, impossibilitando qualquer análise. Miosite discreta ou moderada foi observada principalmente no terço inferior do esôfago, raramente associada a ninhos de amastigotas. A contagem de gânglios e neurônios não demonstrou desnervação. Apesar de em nenhum dos cães ter sido induzida a formação de megaesôfago, relatamos lesões do plexo de Auerbach e de miocélulas do esôfago de animais na fase aguda da infecção chagásica. Este parece ser o primeiro estudo quantitativo e qualitativo sistemático dos plexos de Auerbach e Meissner do esôfago na tripanosomíase cruzi experimental.

    Embryonic stem (ES) cells have high self-renewal capacity and the potential to differentiate into a large variety of cell types. To investigate gene networks operating in pluripotent ES cells and their derivatives, the "Functional Genomics in Embryonic Stem Cells" consortium (FunGenES) has analyzed the transcriptome of mouse ES cells in eleven diverse settings representing sixty-seven experimental conditions. To better illustrate gene expression profiles in mouse ES cells, we have organized the results in an interactive database with a number of features and tools. Specifically, we have generated clusters of transcripts that behave the same way under the entire spectrum of the sixty-seven experimental conditions; we have assembled genes in groups according to their time of expression during successive days of ES cell differentiation; we have included expression profiles of specific gene classes such as transcription regulatory factors and Expressed Sequence Tags; transcripts have been arranged in "Expression Waves" and juxtaposed to genes with opposite or complementary expression patterns; we have designed search engines to display the expression profile of any transcript during ES cell differentiation; gene expression data have been organized in animated graphs of KEGG signaling and metabolic pathways; and finally, we have incorporated advanced functional annotations for individual genes or gene clusters of interest and links to microarray and genomic resources. The FunGenES database provides a comprehensive resource for studies into the biology of ES cells.

    Full Text Available Electroporation is used to induce homologous recombination in the genome of the murine ES (embryonic stem cells. Routinelly subconfluent ES cells are recommended to be used in such experiments. Electroporation of immunoglobulin specific targeting vectors with different length of homology leads to reduced number of selected colonies. The enrichment of double selected colonies is high and thus the amount of HM-1 ES cell colonies for the analysis is very low. Here we show that the electroporation of confluent HM-1 ES cells leads to an increased amount of simple and double selected colonies.

The major issues associated with catalog-based commerce systems are: difficulty in distinguishing one retailer from another, complex navigation with confusing links, and a lack of personalized service. This paper reports an intelligent solution to address these issues. Our solution will provide a more personalized sales experience through the use of a transaction-based knowledge model that includes both the rules used for reasoning as well as the corresponding actions. Based on this solution, we have developed an intelligent electronic sales platform that is supported by a framework which provides the desired personalization as well as extensibility and customization capabilities.

    Full Text Available Ya existen más libros y ensayos sobre "justicia global" en este milenio que en el anterior, al menos según lo que indican las computadoras. Algunos de los temas más amplios que se discuten hoy bajo el título "justicia global" se vienen tratando desde hace siglos, inclusive desde el principio de la civilización, pero se los discutía bajo distintos rótulos, tales como "justicia internacional", "ética internacional" y "la ley de las naciones". Este ensayo explora el significado de tal desplazamiento en la terminología. Un rasgo distintivo del marco filosófico asociado con la expresión "justicia global" es el hecho de destacar el análisis causal y moral del orden institucional global contra el trasfondo de sus alternativas viables y alcanzables. Dentro de este enfoque general de la justicia global, las diferentes concepciones de la justicia global diferirán en los criterios específicos de justicia global que proponen. No obstante ello, esos criterios coincidirán en enfatizar la cuestión sobre cómo funciona nuestro orden institucional global en comparación con sus alternativas viables y alcanzables, en lo que respecta a los intereses humanos fundamentales que resultan relevantes desde un punto de vista moral. Al extender el análisis institucional moral más allá del estado, esta pregunta centra la atención sobre de qué manera la incidencia masiva actual de la violencia y la pobreza extrema, y los profundos excesos de mortalidad y morbilidad que provocan, se pueden evitar -no sencillamente a través de una mejor conducta por parte de los gobiernos, en el plano interno y el internacional sino también, y de manera mucho más efectiva, a través de reformas institucionales globales que, entre otras cosas, mejorarían esa conducta gubernamental al modificar las opciones a disposición de los gobiernos y los incentivos que enfrentan.There are more books and essays on 'global justice' in this millennium already than in the preceding

    In the last decade we have seen the emergence of a new inter-disciplinary field focusing on the understanding of networks which are dynamic, large, open, and have a structure sometimes called random-biased. The field of Complex Networks is helping us better understand many complex phenomena such as the spread of  deseases, protein interactions, social relationships, to name but a few. Studies in Complex Networks are gaining attention due to some major scientific breakthroughs proposed by network scientists helping us understand and model interactions contained in large datasets. In fact, if we could point to one event leading to the widespread use of complex network analysis is the availability of online databases. Theories of Random Graphs from Erdös and Rényi from the late 1950s led us to believe that most networks had random characteristics. The work on large online datasets told us otherwise. Starting with the work of Barabási and Albert as well as Watts and Strogatz in the late 1990s, we now know th...

The latest success with the heaviest group 6 transactinide seaborgium is highlighted. The formation of a very volatile hexacarbonyl compound Sg(CO6 was observed similarly to its lighter homologues molybdenum and tungsten. The interactions of these gaseous carbonyl complex compounds with quartz surfaces were investigated by thermochromatography. Second-generation experiments are under way to investigate the intramolecular bond between the central metal atom of the complexes and the ligands addressing the influence of relativistic effects in the heaviest compounds. Our contribution comprises some aspects of the ongoing challenging experiments as well as an outlook towards other interesting compounds related to volatile complex compounds in the gas phase.

La práctica violenta es parte de una forma de ser que define a los miembros de este grupo y que conforma un complejo sistema que otorga prestigio y honor a los practicantes de acciones violentas. La honra de los violentos se sustenta en una base de aceptación de las prácticas distintivas; base que es construida a través de distintas herramientas que confieren legitimidad a prácticas que son socialmente estigmatizadas. Analizaremos cómo ciertas particularidades del espacio, del barrio, son los asideros lógicos, que construyen los adherentes de la hinchada para reconocer la validez de sus acciones. Pretendemos desnudar la lógica subyacente de esta construcción: la retórica de instaurar la validez de las acciones en la morfología del espacio encubre que son los sentidos de las relaciones sociales las que validan prácticas y representaciones.This work intends to analyze one of the legitimation mechanisms that use the hooligans of a soccer gang to make acceptable their violent actions. Violent practice is part of a way of being that defines the members of this group and forms a complex system that grants prestige and honor to those who perform it. The honor of violent people is founded on the acceptance of distinctive practices; a basis that is built through different tools that confer legitimacy to practices that are socially stigmatized. We will analyze how certain particularities of space, neighborhood, are the logical handholds that hooligans build to recognize their actions validity. We seek to reveal the underlying logic of this construction: the rhetoric of establishing the action validity on the space morphology hides that practices and representations are validated by the sense of the social relationships.

    Physical analogs have shown considerable promise for understanding the behavior of complex adaptive systems, including macroeconomics, biological systems, social networks, and electric power markets. Many of today’s most challenging technical and policy questions can be reduced to a distributed economic control problem. Indeed, economically-based control of large-scale systems is founded on the conjecture that the price-based regulation (e.g., auctions, markets) results in an optimal allocation of resources and emergent optimal system control. This paper explores the state of the art in the use physical analogs for understanding the behavior of some econophysical systems and to deriving stable and robust control strategies for them. In particular we review and discussion applications of some analytic methods based on the thermodynamic metaphor according to which the interplay between system entropy and conservation laws gives rise to intuitive and governing global properties of complex systems that cannot be otherwise understood.

    Zebrafish offers an excellent opportunity to combine embryological, genetic and molecular analyses of vertebrate development in vivo. Embryonic stem (ES) cells have enormous potential to study developmental potency and differentiation in vitro and thus to complement in vivo approaches. Zebrafish ES-like cells have been produced on a feeder cell layer. Here, we report the derivation of Z428, a zebrafish ES-like cell line, from blastula embryos in feeder-free culture. Fetal bovine serum, fish serum, fish embryo extract, basic fibroblast growth factor, non-essential amino acids and 2-mercaptoethanol were found to be important for Z428 growth. After more than 120 passages and many freezing/thawing cycles over a period of 20 years, Z428 exhibits stable growth and manifests many ES cell features including an ES cell phenotype, high alkaline phosphatase activity and spontaneous differentiation in culture. Most importantly, Z428 was transplantable to blastula hosts and capable of contributing to embryonic tissues and organ systems of the three germ layers. Therefore, Z428 is a stable cell line and contains ES-like cells with pluripotency in vitro and in vivo, and a feeder layer is dispensable for ES-like cell derivation in zebrafish. The derivation and easy maintenance of zebrafish ES-like cells under feeder-free conditions provide a useful extension of the present toolbox for studying development and differentiation in the zebrafish model.

    Embryonic stem (ES) and induced pluripotent stem (iPS) cells are pluripotent and can give rise to all cell types. ES/iPS cells have a unique transcriptional circuit that sustains the pluripotent state. These cells also possess a characteristically high rate of proliferation as well as an abbreviated G1 phase. These unique molecular properties distinguish ES and iPS cells from somatic cells. Mouse ES/iPS cells are in a high-flux metabolic state, with a high dependence on threonine catabolism. However, little is known about amino acid metabolism in human ES/iPS cells. Recently, we reported that human ES/iPS cells require high amounts of methionine (Met) and express high levels of Met metabolism enzymes (Shriaki N, et al: Cell Metabolism, 2014). Met deprivation results in a rapid decrease in intracellular S-adenosyl-methionine (SAM), triggering the activation of p53 signaling, reducing pluripotent marker gene NANOG expression, and poising human ES/iPS cells for differentiation, follow by potentiated differentiation into all three germ layers. However, when exposed to prolonged Met deprivation, the cells went to apoptosis. In this review, we explain the importance of SAM in Met metabolism and its relationship with pluripotency, cell survival, and differentiation of human ES/iPS cells.

    Total mass of mitochondria increases during cell proliferation and differentiation through mitochondrial biogenesis, which includes mitochondrial proliferation and growth. During the mitochondrial growth, individual mitochondria have been considered to be enlarged independently of mitochondrial fusion. However, molecular basis for this enlarging process has been poorly understood. Cone photoreceptor cells in the retina possess large mitochondria, so-called mega-mitochondria that have been considered to arise via the enlarging process. Here we show that ES1 is a novel mitochondria-enlarging factor contributing to form mega-mitochondria in cones. ES1 is specifically expressed in cones and localized to mitochondria including mega-mitochondria. Knockdown of ES1 markedly reduced the mitochondrial size in cones. In contrast, ectopic expression of ES1 in rods significantly increased both the size of individual mitochondria and the total mass of the mitochondrial cluster without changing the number of them. RNA-seq analysis showed that ERRα and its downstream mitochondrial genes were significantly up-regulated in the ES1-expressing rods, suggesting facilitation of mitochondrial enlargement via ERRα-dependent processes. Furthermore, higher energy state was detected in the ES1-expressing rods, indicating that the enlarged mitochondria by ES1 are capable of producing high energy. ES1 is the mitochondrial protein that is first found to promote enlargement of individual mitochondria.

    TeV blazars are known as prominent nonthermal emitters across the entire electromagnetic spectrum with their photon power peaking in the X-ray and TeV bands. If distant, absorption of gamma-ray photons by the extragalactic background light (EBL) alters the intrinsic TeV spectral shape, thereby affecting the overall interpretation. Suzaku observations for two of the more distant TeV blazars known to date, 1ES 1101-232 and 1ES 1553+113, were carried out in 2006 May and July, respectively, including a quasi-simultaneous coverage with the state-of-the-art Cerenkov telescope facilities. We report on the resulting data sets with emphasis on the X-ray band and set in context to their historical behavior. During our campaign, we did not detect any significant X-ray or gamma-ray variability. 1ES 1101-232 was found in a quiescent state with the lowest X-ray flux ever measured.

    Background Successful malaria vector control depends on understanding behavioural interactions between mosquitoes and humans, which are highly setting-specific and may have characteristic features in urban environments. Here mosquito biting patterns in Dar es Salaam, Tanzania are examined and the protection against exposure to malaria transmission that is afforded to residents by using an insecticide-treated net (ITN) is estimated. Methods Mosquito biting activity over the course of the night was estimated by human landing catch in 216 houses and 1,064 residents were interviewed to determine usage of protection measures and the proportion of each hour of the night spent sleeping indoors, awake indoors, and outdoors. Results Hourly variations in biting activity by members of the Anopheles gambiae complex were consistent with classical reports but the proportion of these vectors caught outdoors in Dar es Salaam was almost double that of rural Tanzania. Overall, ITNs confer less protection against exophagic vectors in Dar es Salaam than in rural southern Tanzania (59% versus 70%). More alarmingly, a biting activity maximum that precedes 10 pm and much lower levels of ITN protection against exposure (38%) were observed for Anopheles arabiensis, a vector of modest importance locally, but which predominates transmission in large parts of Africa. Conclusion In a situation of changing mosquito and human behaviour, ITNs may confer lower, but still useful, levels of personal protection which can be complemented by communal transmission suppression at high coverage. Mosquito-proofing houses appeared to be the intervention of choice amongst residents and further options for preventing outdoor transmission include larviciding and environmental management.

    TeV blazars are known as prominent nonthermal emitters across the entire electromagnetic spectrum with their photon power peaking in the X-ray and TeV bands. If distant, absorption of γ-ray photons by the extragalactic background light (EBL) alters the intrinsic TeV spectral shape, thereby affecting the overall interpretation. Suzaku observations for two of the more distant TeV blazars known to date, 1ES 1101-232 and 1ES 1553+113, were carried out in 2006 May and July, respectively, including a quasi-simultaneous coverage with the state-of-the-art Cerenkov telescope facilities.

The combined XIS and HXD PIN data for 1ES 1101-232 and 1ES 1553+113 clearly indicate spectral curvature up to the highest hard X-ray data point (~30 keV), manifesting as softening with increasing energy. We describe this spectral shape by either a broken power law or a log-parabolic fit with equal statistical goodness of fits. The combined 1ES 1553+113 very high energy spectrum (90-500 GeV) did not show any significant changes with respect to earlier observations. The resulting contemporaneous broadband spectral energy distributions of both TeV blazars are discussed in view of implications for intrinsic blazar parameter values, taking into account the γ-ray absorption in the EBL.

    Vibrio fischeri ES114, an isolate from the Euprymna scolopes light organ, produces little bioluminescence in culture but is ∼1,000-fold brighter when colonizing the host. Cell-density-dependent regulation alone cannot explain this phenomenon, because cells within colonies on solid medium are much dimmer than symbiotic cells despite their similar cell densities. To better understand this low luminescence in culture, we screened ∼20,000 mini-Tn5 mutants of ES114 for increased luminescence and identified 28 independent "luminescence-up" mutants with insertions in 14 loci. Mutations affecting the Pst phosphate uptake system led to the discovery that luminescence is upregulated under low-phosphate conditions by PhoB, and we also found that ainS, which encodes an autoinducer synthase, mediates repression of luminescence during growth on plates. Other novel luminescence-up mutants had insertions in acnB, topA, tfoY, phoQ, guaB, and two specific tRNA genes. Two loci, hns and lonA, were previously described as repressors of bioluminescence in transgenic Escherichia coli carrying the light-generating lux genes, and mutations in arcA and arcB were consistent with our report that Arc represses lux. Our results reveal a complex regulatory web governing luminescence and show how certain environmental conditions are integrated into regulation of the pheromone-dependent lux system.

    The relationship between women's access to economic resources, e.g. employment or access to micro-credit, and experience of intimate partner violence is complex. Empirical evidence documents that in some settings women's employment is associated with higher risk of partner violence but in other settings with lower risk. Evidence also shows that these conflicting associations exist not only between countries but also within different country settings. Using two population-based data sets gathered in 2002 in contrasting Tanzania settings-Dar es Salaam and Mbeya-, we used multivariate logistic regression to examine the relationship between women's access to economic resources and partner violence. Two indicators of economic resources were examined: whether women earned money and whether women owned a business either with someone or exclusively. In Dar es Salaam we found evidence of a higher risk association among women who earned money and who owned a business exclusively by themselves and a lower risk association among women who owned a business with someone. We found no relationship between either indicator of economic resources and partner violence in Mbeya. Other factors were similarly associated with partner violence in both settings and the strongest associations found were related to the respondents' partners: refusal to give money; alcohol use and relationships with other women. The findings support the assertion that women's access to economic resources operate differently in different country settings, thus highlighting the need for targeted prevention efforts that are relevant for the context.

    Embryonic stem cells (ESCs) have previously been reported to reprogram somatic cells following fusion. The resulting ES-somatic cell hybrids have been shown to adopt the transcriptional profile of ESCs, suggesting that the pluripotent program is dominant. ES-somatic cell hybrids have most characteristics of pluripotent cells in vitro; however, it remains unclear whether the somatic genome is an active partner in the hybrid cells or simply retained predominately as silent cargo. Furthermore, the functional properties of ES-somatic cell hybrids in vivo have been limited to studies on their contribution to teratomas and developing embryos/chimeras. The extent of their pluripotency remains largely unclear. Here we determined that the somatic genome is actively transcribed by generating ES-somatic cell hybrids using Rag2-deficient ESCs fused to autologous wild-type somatic cells. Rag2 expression was detected during in vitro differentiation, suggesting that the somatic genome follows the correct temporal cues during differentiation. Furthermore, ES-somatic cell hybrids maintain their tetraploid state following 4 weeks of differentiation in vivo and are immune tolerated when transferred into matched individuals. The ES-somatic cell hybrids can efficiently differentiate into hematopoietic precursors in both myeloid and lymphoid lineages in vitro, suggesting that the somatic genome is actively transcribed following cell fusion based reprogramming. However, the ES-somatic cell hybrids showed an altered hematopoietic potential following in vitro differentiation and were unable to show hematopoietic engraftment in a mouse model.

  1. Identification and Characterization of MtoA: a Decaheme c-Type Cytochrome of the Neutrophilic Fe(II-oxidizing Bacterium Sideroxydans lithotrophicus ES-1

    Full Text Available The Gram-negative bacterium Sideroxydans lithotrophicus ES-1 (ES-1 grows on FeCO3 or FeS at oxic-anoxic interfaces at circumneutral pH, and the ES-1-mediated Fe(II oxidation occurs extracellularly. However, the molecular mechanisms underlying ES-1’s ability to oxidize Fe(II remain unknown. Survey of the ES-1 genome for candidate genes for microbial extracellular Fe(II oxidation revealed that it contained a three-gene cluster encoding homologues of MtrA, MtrB and CymA of Shewanella oneidensis MR-1 (MR-1 that are involved in extracellular Fe(III reduction. Homologues of MtrA and MtrB were also involved in extracellular Fe(II oxidation by Rhodopseudomonas palustris TIE-1. To distinguish them from those found in MR-1, the identified homologues were named MtoAB and CymAES-1. Cloned mtoA partially complemented an MR-1 mutant without MtrA with regards to ferrihydrite reduction. Characterization of purified MtoA showed that it was a decaheme c-type cytochrome and oxidized soluble Fe(II. Oxidation of Fe(II by MtoA was pH- and Fe(II-complexing ligand-dependent. Under conditions tested, MtoA oxidized Fe(II from pH 7-9 with the optimal rate at pH 9. MtoA oxidized Fe(II complexed with different ligands at different rates. The reaction rates followed the order Fe(IICl2 > Fe(II-citrate > Fe(II-NTA > Fe(II-EDTA with the second-order rate constants ranging from 6.3 × 10-3 μM-1s-1 for oxidation of Fe(IICl2 to 1.0 × 10-3 μM-1s-1 for oxidation of Fe(II-EDTA. Thermodynamic modeling shows that redox reaction rates for the different Fe(II-complexes correlated with their respective estimated reaction-free energies. Collectively, these results demonstrate that MtoA is a functional Fe(II-oxidizing protein and, by working in concert with MtoB and CymAES 1, may oxidize Fe(II at the bacterial surface and transfer released electrons across the bacterial cell envelope to the quinone pool in the inner membrane during extracellular Fe(II oxidation by ES-1.

    Mather, John C.

    What explains the extraordinary complexity of the observed universe, on all scales from quarks to the accelerating universe? My favorite explanation (which I certainty did not invent) ls that the fundamental laws of physics produce natural instability, energy flows, and chaos. Some call the result the Life Force, some note that the Earth is a living system itself (Gaia, a "tough bitch" according to Margulis), and some conclude that the observed complexity requires a supernatural explanation (of which we have many). But my dad was a statistician (of dairy cows) and he told me about cells and genes and evolution and chance when I was very small. So a scientist must look for me explanation of how nature's laws and statistics brought us into conscious existence. And how is that seemll"!gly Improbable events are actually happening a!1 the time? Well, the physicists have countless examples of natural instability, in which energy is released to power change from simplicity to complexity. One of the most common to see is that cooling water vapor below the freezing point produces snowflakes, no two alike, and all complex and beautiful. We see it often so we are not amazed. But physlc!sts have observed so many kinds of these changes from one structure to another (we call them phase transitions) that the Nobel Prize in 1992 could be awarded for understanding the mathematics of their common features.

  3. Cosmic Complexity

    What explains the extraordinary complexity of the observed universe, on all scales from quarks to the accelerating universe? My favorite explanation (which I certainty did not invent) ls that the fundamental laws of physics produce natural instability, energy flows, and chaos. Some call the result the Life Force, some note that the Earth is a living system itself (Gaia, a "tough bitch" according to Margulis), and some conclude that the observed complexity requires a supernatural explanation (of which we have many). But my dad was a statistician (of dairy cows) and he told me about cells and genes and evolution and chance when I was very small. So a scientist must look for me explanation of how nature's laws and statistics brought us into conscious existence. And how is that seemll"!gly Improbable events are actually happening a!1 the time? Well, the physicists have countless examples of natural instability, in which energy is released to power change from simplicity to complexity. One of the most common to see is that cooling water vapor below the freezing point produces snowflakes, no two alike, and all complex and beautiful. We see it often so we are not amazed. But physlc!sts have observed so many kinds of these changes from one structure to another (we call them phase transitions) that the Nobel Prize in 1992 could be awarded for understanding the mathematics of their common features. Now for a few examples of how the laws of nature produce the instabilities that lead to our own existence. First, the Big Bang (what an insufficient name!) apparently came from an instability, in which the "false vacuum" eventually decayed into the ordinary vacuum we have today, plus the most fundamental particles we know, the quarks and leptons.

    Aromaticity of pyrazolopyridazin(on)es was investigated using NICS(0), NICS(1), NICSzz(1), FIPC-NICS and HOMA aromaticity indexes and it was observed that aromaticity of pyridazin(on)es was amenable to aromaticity of pyrazole and vice versa. Some tautomeric forms of pyridazinone were analyzedand the localized orbital locator maps, electron density maps, Fuzzy, Laplacian, and Mayer bond order methods showed dominant form. Different substituents, amine, chlorine, phenyl, methyl, hydrogen, substituted-phenyl, etc. on both the rings were chosen to search out the substituent effect. Aromaticity of pyrazolopyridazin(on)es was searched out in detail for the first time.

    Full Text Available L’Afrique est le continent où la situation sanitaire et sociale est la plus préoccupante et la réalisation des Objectifs du Millénaire pour le Développement la plus lente. L’accès à l’aide mondiale en faveur de la santé est complexe du fait de sa mobilisation au travers de nouveaux mécanismes de financement : les partenariats publics privés mondiaux ou les financements dits innovants. Notre propos est de montrer en quoi l’efficacité de cette aide, de plus en plus volumineuse, passe par une répartition plus équitable entre les pays d’un même continent, ou entre malades présentant des pathologies différentes, des ressources financières et de l’expertise technique, ainsi que par une allocation plus rationnelle des financements qui serait davantage fondée sur des critères plus objectifs tels que les données épidémiologiques, l’efficience des interventions choisies, les données de population, etc. Nous pensons que l’insécurité alimentaire y compris dans les villes, les inégalités d’accès aux financements mondiaux de l’aide en santé, combinées à la croissance démographique sans précédent en Afrique, et aux retentissements de la crise économique et financière mondiale, mettent en péril la stabilité politique de l’Afrique francophone. Pour éviter que la situation ne se détériore davantage, la France et l’Europe, qui ont une responsabilité historique à l’égard de cette région du monde, doivent veiller à ce que les ressources humaines et financières, allouées aux initiatives mondiales, aux dépens de l’aide bilatérale, bénéficient aussi aux personnes les plus démunies d’Afrique francophone.

    Embryonic stem (ES) and induced pluripotent stem (iPS) cells can differentiate into any type of tissue when grown in a suitable culture environment and are considered valuable tools for regenerative medicine. In the field of hematology, generation of hematopoietic stem cells (HSCs) and mature hematopoietic cells (HCs) from ES and iPS cells through mesodermal cells, the ancestors of HCs, can facilitate transplantation and transfusion therapy. Several studies report generation of functional HCs from both mouse and human ES and iPS cells. This approach will likely be applied to individual patient-derived iPS cells for regenerative medicine approaches and drug screening in the future. Here, we summarize current studies of HC-generation from ES and iPS cells.

  4. Lignin Induces ES Cells to Differentiate into Neuroectodermal Cells through Mediation of the Wnt Signaling Pathway.

    Directory of Open Access Journals (Sweden)

    Yu Inoue

    Full Text Available Embryonic stem cells (ES cells are characterized by their pluripotency and infinite proliferation potential. Ever since ES cells were first established in 1981, there have been a growing number of studies aimed at clinical applications of ES cells. In recent years, various types of differentiation inducement systems using ES cells have been established. Further studies have been conducted to utilize differentiation inducement systems in the field of regenerative medicine. For cellular treatments using stem cells including ES cells, differentiation induction should be performed in a sufficient manner to obtain the intended cell lineages. Lignin is a high-molecular amorphous material that forms plants together with cellulose and hemicelluloses, in which phenylpropane fundamental units are complexly condensed. Lignin derivatives have been shown to have several bioactive functions. In spite of these findings, few studies have focused on the effects of lignin on stem cells. Our study aimed to develop a novel technology using lignin to effectively induce ES cells to differentiate into neuroectodermal cells including ocular cells and neural cells. Since lignin can be produced at a relatively low cost in large volumes, its utilization is expected for more convenient differentiation induction technologies and in the field of regenerative medicine in the future.

    Pluripotent stem cells, i.e., embryonic stem (ES) and induced pluripotent stem (iPS) cells, can indefinitely proliferate without commitment and differentiate into all cell lineages. ES cells are derived from the inner cell mass of the preimplantation blastocyst, whereas iPS cells are generated from somatic cells by overexpression of a few transcription factors. Many studies have demonstrated that mouse and human iPS cells are highly similar but not identical to their respective ES cell counterparts. The potential to generate basically any differentiated cell types from these cells offers the possibility to establish new models of mammalian development and to create new sources of cells for regenerative medicine. ES cells and iPS cells also provide useful models to study connexin expression and gap-junctional intercellular communication (GJIC) during cell differentiation and reprogramming. In 1996, we reported connexin expression and GJIC in mouse ES cells. Because a substantial number of papers on these subjects have been published since our report, this Mini Review summarizes currently available data on connexin expression and GJIC in ES cells and iPS cells during undifferentiated state, differentiation, and reprogramming.

    Embryonic stem (ES) cells derived from the pre-implantation blastocyst-stage embryos have been widely used to investigate the molecular events determining pluripotency and cell lineage differentiation. As the first discovered ES-specific transcription factor, Oct4 has been considered as the core pluripotency factor of ES cells. In the present study, we successfully established seven ES lines from the blastocysts collected from female OG2 (Oct4-GFP transgenic) mice, which have been crossed with male rtTA transgenic mice. The pluripotency of the ES cell lines can be visualized by the expression of Oct4-GFP under fluorescent microscopy and germ-line transmission capability has been further confirmed. More importantly, the presence of rtTA could induce transgene’s expression with the help of doxycycline. Therefore, these ES cell lines provide an excellent tool to further discover novel factors affecting pluripotency and to investigate the molecular mechanism of reprogramming in defined transcription factors mediated nuclear reprogramming.

    We examine the HI+H_2 content of blue-sequence E/S0s -- a recently identified population of galaxies that are morphologically early type, but reside alongside spiral galaxies in color vs. stellar mass space. We test the idea that the majority of low-to-intermediate mass blue-sequence E/S0s may be settled products of past mergers evolving toward later-type morphology via disk regrowth. We find that blue-sequence E/S0s with stellar masses 1.0, comparable to those of spiral galaxies. Preliminary CO(1-0) maps reveal disk-like rotation of molecular gas in the inner regions of several of our blue-sequence E/S0s, which suggests that they may have gas disks suitable for stellar disk regrowth. At the current rate of star formation, many of our blue-sequence E/S0s will exhaust their atomic gas reservoirs in <~ 3 Gyr. Over the same time period, most of these galaxies are capable of substantial growth in the stellar component. Star formation in blue-sequence E/S0s appears to be bursty, and likely involves inflow trig...

  9. Live cell imaging of the nascent inactive X chromosome during the early differentiation process of naive ES cells towards epiblast stem cells.

    Directory of Open Access Journals (Sweden)

    Aurélia Guyochin

    Full Text Available Random X-chromosome inactivation ensures dosage compensation in mammals through the transcriptional silencing of one of the two X chromosomes present in each female cell. Silencing is initiated in the differentiating epiblast of the mouse female embryos through coating of the nascent inactive X chromosome by the non-coding RNA Xist, which subsequently recruits the Polycomb Complex PRC2 leading to histone H3-K27 methylation. Here we examined in mouse ES cells the early steps of the transition from naive ES cells towards epiblast stem cells as a model for inducing X chromosome inactivation in vitro. We show that these conditions efficiently induce random XCI. Importantly, in a transient phase of this differentiation pathway, both X chromosomes are coated with Xist RNA in up to 15% of the XX cells. In an attempt to determine the dynamics of this process, we designed a strategy aimed at visualizing the nascent inactive X-chromosome in live cells. We generated transgenic female XX ES cells expressing the PRC2 component Ezh2 fused to the fluorescent protein Venus. The fluorescent fusion protein was expressed at sub-physiological levels and located in nuclei of ES cells. Upon differentiation of ES cell towards epiblast stem cell fate, Venus-fluorescent territories appearing in interphase nuclei were identified as nascent inactive X chromosomes by their association with Xist RNA. Imaging of Ezh2-Venus for up to 24 hours during the differentiation process showed survival of some cells with two fluorescent domains and a surprising dynamics of the fluorescent territories across cell division and in the course of the differentiation process. Our data reveal a strategy for visualizing the nascent inactive X chromosome and suggests the possibility for a large plasticity of the nascent inactive X chromosome.

  16. Regulation of Pax6 by CTCF during induction of mouse ES cell differentiation.

    Directory of Open Access Journals (Sweden)

    Jie Gao

    Full Text Available Pax6 plays an important role in embryonic cell (ES differentiation during embryonic development. Expression of Pax6 undergoes from a low level to high levels following ES cell differentiation to neural stem cells, and then fades away in most of the differentiated cell types. There is a limited knowledge concerning how Pax6 is regulated in ES cell differentiation. We report that Pax6 expression in mouse ES cells was controlled by CCCTC binding factor (CTCF through a promoter repression mechanism. Pax6 expression was significantly enhanced while CTCF activity was kept in the constant during ES cell differentiation to radial glial cells. Instead, the interaction of CTCF with Pax6 gene was regulated by decreased CTCF occupancy in its binding motifs upstream from Pax6 P0 promoter following the course of ES cell differentiation. Reduced occupancy of CTCF in the binding motif region upstream from the P0 promoter was due to increased DNA methylations in the CpG sites identified in the region. Furthermore, changes in DNA methylation levels in vitro and in vivo effectively altered methylation status of these identified CpG sites, which affected ability of CTCF to interact with the P0 promoter, resulting in increases in Pax6 expression. We conclude that there is an epigenetic mechanism involving regulations of Pax6 gene during ES cell differentiation to neural stem cells, which is through increases or decreases in methylation levels of Pax6 gene to effectively alter the ability of CTCF in control of Pax6 expression, respectively.

Trata-se de pesquisa qualitativa cujo objetivo foi (1 compreender se mães acompanhantes identificavam a enfermeira, bem como os outros componentes da equipe de enfermagem (técnica e auxiliares, e (2 conhecer suas percepções acerca dos cuidados prestados pela equipe de enfermagem. Foram entrevistadas, individualmente, 8 mães acompanhantes das crianças internadas. Os discursos foram submetidos à análise temática de conteúdo. Obteve-se duas categorias: identificação da enfermeira/equipe de enfermagem pelas mães acompanhantes e percepção das mães acompanhantes acerca da equipe de enfermagem. Na primeira categoria constatou-se dificuldade na identificação dos componentes da equipe de enfermagem. Na segunda, constatou-se que a atividade de enfermagem é percebida como subordinada à área médica. Eventualmente as mães têm dificuldade para distingüir o que é realizado pela enfermeira ou pelos outros componentes da equipe, mas todos os cuidados são avaliados como muito bons. Além disso, a enfermeira é percebida como aquela que resolve qualquer problema. Enfermagem é percebida pelas mães acompanhantes como atividade mediada pela representação de maternidade. Conclui-se que o cuidado realizado por esta equipe, apesar de ser visto como muito bom, ainda precisa ser apresentado às mães como profissional e autônomo, a fim de se superar a visão estereotipada de enfermagem.

    2001-06-01

    Full Text Available En este ensayo clasificatorio presentamos cinco tipos básicos de multidimensionalidad en la literatura reciente sobre desarrollo y pobreza. El primer tipo básico es intra- económico pues incluye dos o más variables económicas. El segundo añade indicadores no económicos al ingreso. Podemos distinguir dos variantes en ese caso. Una de ellas es la que introduce la multidimensionalidad en el campo de los factores de la pobreza, usualmente de ingreso. Algunos de esos factores son definidos como (capital,. Otra es la que incorpora elementos no económicos en la definición de pobreza. El tercer tipo de multidimensionalidad elimina el ingreso y las variables económicas de la definición de pobreza, lo que coloca a la dimensión económica meramente como un factor. Es el caso del planteamiento de Sen que define el problema como uno de libertad, en última instancia. Dentro de ese enfoque nos interesa destacar una de las maneras menos comprendidas de hacerlo cual es la que sirve para construir el Índice de Desarrollo Humano en los Informes sobre Desarrollo Humano del PNUD. La cuarta manera de establecer la multidimensionalidad de la pobreza es la que introduce la clasificación “económica”, “política”, “social” “cultural” u otras, y que se deriva de la modalidad de separación de esferas de la vida propia del mundo liberal. La última que exponemos es la que se apoya directamente en las ideas de lo valioso en la vida y su relación con el desarrollo que tienen diversas corrientes filosóficas.

  4. Searching for a placental derived ES-62-like molecule to explain rheumatoid arthritis amelioration in pregnancy

    Directory of Open Access Journals (Sweden)

    Craig D. Scoville

    2014-11-01

    Full Text Available The majority of women with rheumatoid arthritis (RA experience disease amelioration during pregnancy for unclear reasons. One possible explanation pursued and described here is whether the placenta produces a protein similar to the immunomodulating protein, ES-62, excreted by filarial nematodes. This protein has also been shown to reduce disease activity in animal models of RA. Eleven human placentas were prepared and a polyclonal anti-ES-62 antiserum was used to identify if any ES-62-like molecule exists from human placental tissues. Any bands identified were then excised from the gel and sent for mass spectrometry and protein identification. The anti-serum showed consistent cross reactivity with the heavy chain from immunoglobulin G (IgG from the eleven human placentas by mass spectrometry. No primary sequence homology between the heavy chain of IgG and ES-62 was identified. The placenta does not produce an ES-62-like molecule. However the binding of the antiserum to the Fc region of IgG suggests that this may be a possible mechanism for rheumatoid factor production in some patients with chronic filarial infections.

    Embryonic stem (ES) cells differentiate into various cell lineages in vitro. A procedure was previously designed to promote the differentiation of ES cells towards the melanocyte lineage and to obtain large and reproducible amounts of melanocytes. To elucidate the main events that lead to the development of melanocytes in vitro, we used transgenic Dct::lacZ mouse blastocysts to establish ES cell lines expressing the lacZ reporter gene under the control of the Dct promoter. Dct, a melanoblast marker, is expressed just after melanoblast determination in vivo. We evaluated the importance of recruitment, proliferation and differentiation during melanocyte ontogeny after the in vitro differentiation of Dct::lacZ ES cells into melanocytes. We showed that bFGF and cholera toxin induce precocious melanoblast determination, associated with early melanocyte differentiation. Edn3 induced melanoblast proliferation and long-term melanoblast recruitment, but not precocious determination. The lack of basic Fibroblast Growth Factor (bFGF) and cholera toxin can be partially compensated by Edn3. Thus, Dct::lacZ ES cells can be used as a model to study determination, proliferation and differentiation in the melanocyte lineage in vitro.

    Full Text Available ES-62, an immunomodulator secreted by filarial nematodes, exhibits therapeutic potential in mouse models of allergic inflammation, at least in part by inducing the desensitisation of FcεRI-mediated mast cell responses. However, in addition to their pathogenic roles in allergic and autoimmune diseases, mast cells are important in fighting infection, wound healing, and resolving inflammation, reflecting that mast cells exhibit a phenotypic and functional plasticity. We have therefore characterised the differential functional responses to antigen (via FcεRI and LPS and their modulation by ES-62 of the mature peritoneal-derived mast cells (PDMC; serosal and those of the connective tissue-like mast cells (CTMC and the mucosal-like mast cells derived from bone marrow progenitors (BMMC as a first step to produce disease tissue-targeted therapeutics based on ES-62 action. All three mast cell populations were rendered hyporesponsive by ES-62 and whilst the mechanisms underlying such desensitisation have not been fully delineated, they reflect a downregulation of calcium and PKCα signalling. ES-62 also downregulated MyD88 and PKCδ in mucosal-type BMMC but not PDMC, the additional signals targeted in mucosal-type BMMC likely reflecting that these cells respond to antigen and LPS by degranulation and cytokine secretion whereas PDMC predominantly respond in a degranulation-based manner.

    SUMMARY To examine transcription factor (TF) network(s), we created mouse ES cell lines, in each of which one of 50 TFs tagged with a FLAG moiety is inserted into a ubiquitously controllable tetracycline-repressible locus. Of the 50 TFs, Cdx2 provoked the most extensive transcriptome perturbation in ES cells, followed by Esx1, Sox9, Tcf3, Klf4, and Gata3. ChIP-Seq revealed that CDX2 binds to promoters of up-regulated target genes. By contrast, genes down-regulated by CDX2 did not show CDX2 binding, but were enriched with binding sites for POU5F1, SOX2, and NANOG. Genes with binding sites for these core TFs were also down-regulated by the induction of at least 15 other TFs, suggesting a common initial step for ES cell differentiation mediated by interference with the binding of core TFs to their target genes. These ES cell lines provide a fundamental resource to study biological networks in ES cells and mice. PMID:19796622

    2013-01-01

    Full Text Available This paper based on a fast implemented multiphase screen method using DFT puts forward an ionospheric Es layer clutter model and uses the newly developed dimensionality reduction space-time adaptive processing- (STAP- JDL algorithm to suppress Es layer clutter, which proves the validity of the proposed model. Firstly, the multiphase screen method was analyzed, and a fast algorithm using DFT was proposed. Then, based on the multiphase screen method and thorough simulation, we reached a conclusion of the high-frequency radio wave propagation’s fluctuation characteristics in the ionosphere. According to the results of the analysis, a new Es layer ionospheric clutter model was established and was compared with the measured data and verification was made. Finally, based on the built clutter model, JDL algorithm was applied to the high-frequency surface wave radar ionospheric clutter suppression, using the measured data to verify the validity of the model and algorithm. The simulation results showed that the built model can show the characteristics of the ionospheric Es layer clutter and that the JDL algorithm can suppress ionospheric Es layer clutter quite effectively.

    Full Text Available Chaperonin GroEL (Cpn60 requires cofactor GroES (Cpn10 for protein refolding in bacteria that possess single groEL and groES genes in a bicistronic groESL operon. Among 4,861 completely-sequenced prokaryotic genomes, 884 possess duplicate groEL genes and 770 possess groEL genes with no neighboring groES. It is unclear whether stand-alone groEL requires groES in order to function and, if required, how duplicate groEL genes and unequal groES genes balance their expressions. In Myxococcus xanthus DK1622, we determined that, while duplicate groELs were alternatively deletable, the single groES that clusters with groEL1 was essential for cell survival. Either GroEL1 or GroEL2 required interactions with GroES for in vitro and in vivo functions. Deletion of groEL1 or groEL2 resulted in decreased expressions of both groEL and groES; and ectopic complementation of groEL recovered not only the groEL but also groES expressions. The addition of an extra groES gene upstream groEL2 to form a bicistronic operon had almost no influence on groES expression and the cell survival rate, whereas over-expression of groES using a self-replicating plasmid simultaneously increased the groEL expressions. The results indicated that M. xanthus DK1622 cells coordinate expressions of the duplicate groEL and single groES genes for synergistic functions of GroELs and GroES. We proposed a potential regulation mechanism for the expression coordination.

We found that EVX1 repressed GSC expression and promoted formation of posterior streak-like progeny in response to BMP4, and conversely that GSC repressed EVX1...... expression and was required for development of anterior streak-like progeny in response to activin. Chromatin immunoprecipitation assays showed that EVX1 bound to the GSC 5'-flanking region in BMP4 treated human ES cells, and band shift assays identified two EVX1 binding sites in the GSC 5'-region...

    In order to further promote integrated optimization operation of distributed new energy/ energy storage/ active load, this paper studies the integrated photovoltaic-energy storage (PV-ES) system which is connected with the distribution network, and analyzes typical structure and configuration selection for integrated PV-ES generation system. By combining practical grid- connected characteristics requirements and technology standard specification of photovoltaic generation system, this paper takes full account of energy storage system, and then proposes several new grid-connected performance indexes such as paralleled current sharing characteristic, parallel response consistency, adjusting characteristic, virtual moment of inertia characteristic, on- grid/off-grid switch characteristic, and so on. A comprehensive and feasible grid-connected performance index system is then established to support grid-connected performance testing on integrated PV-ES system.

    New photometric follow-up observations of transitting 'hot Jupiters' TrES-3b and Qatar-1b are presented. Weighted mean values of the solutions of light curves in R-filter for both planetary systems are reported and compared with the previous results. The transit light curves were analysed using the WINFITTER code. The physical properties of the planets were estimated. The planet radii are found to be Rp = 1.381 ± 0.033RJ for TrES-3b and Rp = 1.142 ± 0.025RJ for Qatar-1b. Transit times and their uncertainties were also determined and a new linear ephemeris was computed for both systems. Analysis of transit times showed that a significant signal could not be determined for TrES-3b, while weak evidence was found for Qatar-1b, which might be tested using more precise future transit times.

    Based on the discussion about topology structure of integrated distributed photovoltaic (PV) power generation system and energy storage (ES) in single or mixed type, this paper focuses on analyzing grid-connected performance of integrated distributed photovoltaic and energy storage (PV-ES) systems, and proposes a comprehensive evaluation index system. Then a multi-level fuzzy comprehensive evaluation method based on grey correlation degree is proposed, and the calculations for weight matrix and fuzzy matrix are presented step by step. Finally, a distributed integrated PV-ES power generation system connected to a 380 V low voltage distribution network is taken as the example, and some suggestions are made based on the evaluation results.

    Antecedentes El esófago de Barrett es una reconocida lesión precursora de adenocarcinoma esofágico. Aunque generalmente asociada al reflujo gastroesofágico, los mecanismos patogénicos de la enfermedad no son bien conocidos. El objetivo del presente estudio es explorar la historia natural e identificar marcadores de progreso del proceso precanceroso. Material y métodos Se utilizaron cortes histológicos de 67 especímenes de esófago correspondientes a 14 pacientes con esófago de Barrett, a los que se siguió entre 1 – 9 años. Se clasificaron las lesiones en: esófago de Barrett sin displasia, indefinido para displasia o con displasia. Se evaluó la expresión de diferentes mucinas en las células caliciformes y en las columnares usando técnicas de histoquímica e inmunohistoquímica. Resultados En todos los casos se comprobó la presencia de metaplasia intestinal incompleta. Las células columnares dentro del epitelio metaplásico contenían mucinas neutras. A mayor severidad de la lesión se encontró significativamente menor expresión de sialomucinas en las células columnares (p de tendencia igual a 0,03). En sujetos con lesiones indefinidas para displasia se observó un mayor contenido de sulfomucinas en las células caliciformes (p=0,034) y de MUC2 en las células columnares (p=0,029) que en sujetos con esófago de Barrett sin displasia. Se observó expresión de la mucina intestinal MUC2 y de la mucina gástrica MUC5AC en todas las muestras. MUC6, una mucina de las glándulas profundas gástricas, se presentó ocasionalmente. Conclusión La evaluación de los perfiles de mucinas en el esófago de Barrett sugiere una transición gradual del fenotipo del epitelio metaplásico a medida que la lesión avanza en el tiempo.

    This paper deals with the identification of the flux for a system of conservation laws in the specific example of analytic chromatography. The fundamental equations of chromatographic process are highly non linear. The state-of-the-art Evolution Strategy, CMA-ES (the Covariance Matrix Adaptation Evolution Strategy), is used to identify the parameters of the so-called isotherm function. The approach was validated on different configurations of simulated data using either one, two or three components mixtures. CMA-ES is then applied to real data cases and its results are compared to those of a gradient-based strategy.

  16. MicroRNA modulation induced by AICA ribonucleotide in J1 mouse ES cells.

    Full Text Available ES cells can propagate indefinitely, maintain self-renewal, and differentiate into almost any cell type of the body. These properties make them valuable in the research of embryonic development, regenerative medicine, and organ transplantation. MicroRNAs (miRNAs are considered to have essential functions in the maintenance and differentiation of embryonic stem cells (ES cells. It was reported that, strong external stimuli, such as a transient low-pH and hypoxia stress, were conducive to the formation of induced pluripotent stem cells (iPS cells. AICA ribonucleotide (AICAR is an AMP-activated protein kinase activator, which can let cells in the state of energy stress. We have demonstrated that AICAR can maintain the pluripotency of J1 mouse ES cells through modulating protein expression in our previous research, but its effects on ES cell miRNA expression remain unknown. In this study, we conducted small RNA high-throughput sequencing to investigate AICAR influence on J1 mouse ES cells by comparing the miRNA expression patterns of the AICAR-treated cells and those without treatment. The result showed that AICAR can significantly modulate the expression of multiple miRNAs, including those have crucial functions in ES cell development. Some differentially expressed miRNAs were selected and confirmed by real-time PCR. For the differently expressed miRNAs identified, further study was conducted regarding the pluripotency and differentiation associated miRNAs with their targets. Moreover, miR-134 was significantly down-regulated after AICAR treatment, and this was suggested to be directly associated with the up-regulated pluripotency markers, Nanog and Sox2. Lastly, Myc was significantly down-regulated after AICAR treatment; therefore, we predicted miRNAs that may target Myc and identified that AICAR induced up-regulation of miR-34a, 34b, and 34c can repress Myc expression in J1 mouse ES cells. Taken together, our study provide a new mechanism for

    Whether SWI/SNF chromatin remodeling complexes play roles in embryonic stem (ES) cells remains unknown. Here we show that SWI/SNF complexes are present in mouse ES cells, and their composition is dynamically regulated upon induction of ES cell differentiation. For example, the SWI/SNF purified from undifferentiated ES cells contains a high level of BAF155 and a low level of BAF170 (both of which are homologs of yeast SWI3 protein), whereas that from differentiated cells contains near equal amounts of both. Moreover, the levels of BAF250A and BAF250B decrease, whereas that of BRM increases, during the differentiation of ES cells. The altered expression of SWI/SNF components hinted that these complexes could play roles in ES cell maintenance or differentiation. We therefore generated ES cells with biallelic inactivation of BAF250B, and found that these cells display a reduced proliferation rate and an abnormal cell cycle. Importantly, these cells are deficient in self-renewal capacity of undifferentiated ES cells, and exhibit certain phenotypes of differentiated cells, including reduced expression of several pluripotency-related genes, and increased expression of some differentiation-related genes. These data suggest that the BAF250B-associated SWI/SNF is essential for mouse ES cells to maintain its normal proliferation and pluripotency. The work presented here underscores the importance of SWI/SNF chromatin remodeling complexes in pluripotent stem cells. PMID:18323406

    We observed nine primary transits of the hot Jupiter TrES-3b in several optical and near-UV photometric bands from 2009 June to 2012 April in an attempt to detect its magnetic field. Vidotto, Jardine and Helling suggest that the magnetic field of TrES-3b can be constrained if its near-UV light curve shows an early ingress compared to its optical light curve, while its egress remains unaffected. Predicted magnetic field strengths of Jupiter-like planets should range between 8 G and 30 G. Using these magnetic field values and an assumed B_star of 100 G, the Vidotto et al. method predicts a timing difference of 5-11 min. We did not detect an early ingress in our three nights of near-UV observations, despite an average cadence of 68 s and an average photometric precision of 3.7 mmag. However, we determined an upper limit of TrES-3b's magnetic field strength to range between 0.013 and 1.3 G (for a 1-100 G magnetic field strength range for the host star, TrES-3) using a timing difference of 138 s derived from the N...

    Full Text Available La salud es el bien más preciado para el ser humano, de lo cual toma consciencia sobre todo al perderla, o cuando la pérdida ocurre a un ser querido. Por tal motivo, una de las tareas fundamentales del Estado es garantizar la mejor salud posible a los ciudadanos, y esto en Costa Rica se ha hecho en forma muy eficiente, tanto que los indicadores de salud son de los mejores del mundo. Esto no es casual, sino el producto de decisiones políticas del pasado de costarricenses asertivos. Hoy el país enfrenta un gran reto con el crecimiento en la demanda de servicios públicos y el incremento en su costo. Para mantener el legado es preciso tomar decisiones igual de visionarias. Se señala como un alto riesgo de desmejorar estos indicadores, el concentrar los esfuerzos y presupuestos en tratar las enfermedades en sus etapas finales y, por el contrario, se propone dar prioridad a la prevención, con base en el hecho de que las principales causas de mortalidad prematura en los costarricenses, se asocian con factores de riesgo prevenibles. Se recomienda la educación como el camino para prevenir la enfermedad, y se debe involucrar a profesionales en impartir la “educación para la salud”, dirigida primero y formalmente a niños y adolescentes.

  10. BMP4 and FGF strongly induce differentiation of mouse ES cells into oral ectoderm

    Directory of Open Access Journals (Sweden)

    2015-09-01

    Full Text Available During embryonic development, oral ectoderm differentiates into the adenohypophysis, dental epithelia, salivary glands, and nasal pit. Few reports exist concerning the induction of oral ectoderm from embryonic stem (ES cells. Generally, any lot differences in fetal bovine serum (FBS and serum replacer may affect the induction of ES cell-differentiation. Using a previously established culture strategy for differentiation, the proportion of cell aggregates containing Pitx1+ oral ectoderm varied widely between 9–36% when several different lots of FBS or serum replacer were used. We therefore tried to enhance the differentiation method. We found that bone morphogenetic protein (BMP 4 and fibroblast growth factor (FGF treatments improved oral ectoderm induction. Such treatment also improved the differentiation of oral ectoderm into the adenohypophysis. Furthermore, increased BMP4 treatment induced dental epithelium and mesenchyme. Such differentiation suggests that the Pitx1+ layer displays similar properties to oral ectoderm, as found in vivo. Differentiation of ES cells into oral ectoderm using different lots of FBS and serum replacer increased 78–90% after treatment with BMP4 and FGF. In summary, we have established a robust strategy for the induction of oral ectoderm differentiation from mouse ES cells.

    We report on observations of several transit events of the transiting planet TrES-2 obtained with the Cassegrain-Teleskop-Kamera at the University Observatory Jena. Between March 2007 and November 2008 ten different transits and almost a complete orbital period were observed. Overall, in 40 nights of observation 4291 exposures (in total 71.52 h of observation) of the TrES-2 parent star were taken. With the transit timings for TrES-2 from the 34 events published by the TrES-network, the Transit Light Curve project and the Exoplanet Transit Database plus our own ten transits, we find that the orbital period is P=(2.470614 +/- 0.000001) d, a slight change by ~0.6 s compared to the previously published period. We present new ephemeris for this transiting planet. Furthermore, we found a second dip after the transit which could either be due to a blended variable star or occultation of a second star or even an additional object in the system. Our observations will be useful for future investigations of timing varia...

    Although particular chromosomal syndromes are phenotypically and clinically distinct, the majority of individuals with autosomai imbalance, such as aneuploidy, manifest mental retardation. A common abnormal phenotype of Down syndrome (DS), the most prevalent autosomal aneuploidy, shows a reduction in both the number and the density of neurons in the brain. As a DS model, we have recently created chimeric mice from ES cells containing a single human chromosome 21. The mice mimicked the characteristic phenotypic features of DS, and ES cells showed a higher incidence of apoptosis during early neuronal differentiation in vitro. In this study, we examined the induction of anomalous early neural development by aneuploidy in mouse ES cells by transferring various human chromosomes or additional mouse chromosomes. Results showed an elevated incidence of apoptosis in all autosome-aneuploid clones examined during early neuronal differentiation in vitro. Further, cDNA microarray analysis revealed a common cluster of down-regulated genes, of which eight known genes are related to cell proliferation, neurite outgrowth and differentiation. Importantly, targeting of these genes by siRNA knockdown in normal mouse ES cells led to enhanced apoptosis during early neuronal differentiation. These findings strongly suggest that autosomal imbalance is associated with general neuronal loss through a common molecular mechanism for apoptosis.

  11. Lift of the positive preshower endcap (ES+) above CMS, from the UXC55 cavern into the SX5 surface building

    CERN Multimedia

    2013-01-01

    The first part of the endcap calorimetry of CMS, as seen by particles coming from interactions in the centre of CMS, is the "Endcap Preshower", or "ES" for short, with "ES-" and "ES+" being used to distinguish the two ends. The ES is used for particle identification in the highly-occupied endcap regions of CMS. Each ES comprises two orthogonal layers of silicon sensors, interspersed with lead layers that serve to generate electromagnetic showers. In order to withstand the high radiation environment in CMS, the ES silicon sensors need to be cooled; until now they have operated at around 8-10 degrees C, but when CMS restarts for the 2015 run it will need to go down to about -15 degrees C. At the same time, the exterior of the ES needs to be maintained at a constant +18 degrees C. The ES thus contains sophisticated cooling and heating systems! In November 2013 a problem was detected with one section of the ES- heating system and upon investigation traced to a faulty connector at the exterior of the ES- disc. Fur...

    Full Text Available Purpose: To determine role of antigens released in vivo and in vitro in immunodiagnosis of tuberculosis (TB. Methods: In vivo released circulating tuberculosis antigen (CTA was obtained from TB sera by ammonium sulphate precipitation and in vitro released excretory-secretory (ES antigens from Mycobacterium tuberculosis culture filtrate. CTA and ES antigens were fractionated by SDS-PAGE and electro-eluted gel fractions were analysed for antigen by ELISA. Results: Low molecular weight proteins CTA-9 and ES-9 showed high titre of antigen activity. To explore the diagnostic potential of low molecular weight ES antigen, M. tuberculosis ES antigen was further fractionated by gel filtration chromatography followed by purification on anion exchange column using fast protein liquid chromatography and a highly seroreactive ESG-5D (ES-20 antigen was obtained. Competitive inhibition showed that CTA-9 and ES-9 antigens inhibit the binding of ES-20 antigen to its antibody. Seroanalysis showed sensitivity of 83 and 80% for ES-20 antigen and antibody detection, respectively, in pulmonary TB and 90% in lymph node TB. Conclusions: Seroreactivity studies using M. tuberculosis ES-20 antigen showed usefulness in detection of TB; in particular, lymph node TB.

    Multicellular organisms require one or more coevolved ecological interactions to survive and reproduce. Coevolution, the set of reciprocal evolutionary changes between these interacting species, is a continuous process that organizes Darwinian diversity in complex biological webs. This dynamic vision tempers the conflict between Humboldt’s harmonious Nature and the warring Nature held by Darwin and other 19th century naturalists. The conceptual foundations of coevolutionary biology include the germ theory of disease, the ubiquity of symbioses, their frequent feature as specialized interactions, and the Mendelian determination of their outcomes. Those coevolutionary changes, driven ultimately by natural selection, affect hereditary traits involved in the interactions. Since species consist of genetically diverse populations with geographic structure, coevolution between two or more given species may cause qualitative or quantitative differential trait changes according to location, giving rise to geographic

    Full Text Available RACIONAL: A estenose esofágica secundária à ingestão de produtos cáusticos é freqüente no Brasil, principalmente como tentativa de suicídio. O esôfago de Barrett surge como conseqüência do refluxo gastroesofágico crônico. A literatura pesquisada mostrou que esta associação é muito rara. CASUÍSTICA E MÉTODOS: De 1981 a 2000 foram admitidos e tratados no Gastrocentro-UNICAMP (Universidade Estadual de Campinas, SP. 120 doentes com estenose cáustica do esôfago e durante o seguimento destes, foram encontrados 9 casos associados com o esôfago de Barrett (7,5%. O tempo de ingestão do cáustico variou de 4 a 54 anos (média de 29 anos e eram quatro homens e cinco mulheres, oito brancos e um negro, com idade média de 57,7 anos (43 a 72 anos. RESULTADOS: Todos os casos apresentavam disfagia e a endoscopia digestiva alta flexível mostrou áreas de estenose e seqüelas de esofagite cáustica. Três pacientes referiram sintomas de refluxo gastroesofágico, mas hérnia de hiato foi encontrada em apenas um caso. O esôfago de Barrett foi encontrado no terço médio do esôfago em três casos, acima das áreas de estenose, e nos demais, no terço distal. A disfagia foi tratada com dilatações esofágicas periódicas. Dois pacientes apresentando sintomas de refluxo grave foram submetidos a fundoplicatura à Nissen modificado através de videolaparoscopia, com bons resultados. CONCLUSÕES: O esôfago de Barrett nesses doentes poderia estar associado com a ingestão de cáustico, porque nem sempre esteve associado à esofagite por refluxo. É muito importante o seguimento desses doentes e realização periódica de endoscopias digestivas com biopsias do esôfago de Barrett, devido à possibilidade de malignização.BACKGROUND: The esophageal stenosis secondary to the ingestion of caustic products is frequent in Brazil, mainly due to an attempt suicide. The Barrett's esophagus is consequence of the chronic gastroesophageal reflux. The

Desse modo, pretendemos, também, contribuir para uma maior compreensão da forma como, no final do século XIX, a literatura teve uma participação na produção de representações e práticas de masculinidade (e de feminilidade no Brasil.This article aims to identify and analyze different aspects of masculinity presented in the literature of Bernardo Guimarães, an important 19th century Brazilian writer from Minas Gerais. We shall focus how the author, in his literary work, constructs the gender relations and produces representations about men and women, specially the masculine experiences, without forgetting the feminine ones. We intend, in the same way, to contribute to a broader understanding of the participation of literature in the production of representations and practices of masculinity (and of femininity in late nineteenth-century Brazil.

    The experience of a multidisciplinary group of professionals during the emergency following the damaging Lorca 2011 earthquake shows that a more thorough preparation of the population prior to the event would have reduced the effects on the population in general and even possibly reduced the number of victims. Our aim here is to present a realistic and applicable educational project (EsLorca) based on the knowledge and experience obtained in Lorca in order to fill this educational gap. EsLorca is designed as a training project to help students/citizens to achieve the minimum skills necessary to react appropriately during and after a destructive earthquake on the basis of their understanding of earthquake phenomena, from its geological origins to its effects on buildings. In addition to state education, the project intends in its objectives to reach adult and senior citizens. The educational plan consists of a series of activities designed to last 50 minutes, which can be taken part in during academic tutoring sessions and are easy to organise in neighbourhood associations, senior citizens centres, and the work place and so on. Planning for adults and older citizens would be adapted to the specific conditions and needs of each centre or association. The structure of the plan is sequential. Its initial content is related directly to the emergency before passing on to a suitable knowledge and understanding of the geological phenomenon and its consequences. (Author) 13 refs.

Investigar es conocer, es decir estudiar y experimentar una materia o ciencia para aumentar los conocimientos sobre ella. Pero una investigación implica además, como requisito y obligación del investigador, difundir ese conocimiento nuevo adquirido. Vale decir que la publicación no es para el lauro personal sino para compartir el cúmulo de experiencias adquiridas. El conocimiento científico tiene como propósito no sólo comprender las causas de un determinado fenómeno si no también lograr una modificación de su realidad en beneficio de todos. Y la difusión científica se constituye un pilar fundamental como elemento cognitivo para el desarrollo de futuras investigaciones que permitirán adquirir mayor información para la toma decisiones y realización de acciones. Cuando uno se pregunta por qué es importante la publicación en revistas científicas de acceso abierto, de lo expuesto anteriormente resulta que la divulgación en dichas revistas científicas constituye una herramienta fundamental para el investigador, brindando la posibilidad de difusión de su trabajo en pos de una mayor comprensión de los fenómenos sociales que afectan a la comunidad en su conjunto y sirve como plataforma epistémica en el avance del conocimiento.

    Full Text Available The new neutron-deficient nuclei 240Es and 236Bk were synthesised at the gas-filled recoil separator RITU. They were identified by their radioactive decay chains starting from 240Es produced in the fusion–evaporation reaction 209Bi(34S,3n240Es. Half-lives of 6(2s and 22−6+13s were obtained for 240Es and 236Bk, respectively. Two groups of α particles with energies Eα=8.19(3MeV and 8.09(3MeV were unambiguously assigned to 240Es. Electron-capture delayed fission branches with probabilities of 0.16(6 and 0.04(2 were measured for 240Es and 236Bk, respectively. These new data show a continuation of the exponential increase of ECDF probabilities in more neutron-deficient isotopes.

    Full Text Available La hepatitis por virus A (VHA es la más frecuente de las hepatitis virales en el mundo, especialmente en los países subdesarrollados. Donde esta enfermedad es endémica, se suelen realizar un gran número de estudios de laboratorio para confirmarla. El objetivo del presente trabajo fue evaluar la utilidad de investigar anticuerpos IgM anti hepatitis A (IgM anti-VHA para el diagnóstico de la VHA en pacientes con niveles séricos normales de aspartato y alanina aminotransferasas (AST/ALT. Todos los pacientes que concurrieron al laboratorio con solicitud de enzimograma hepático y anticuerpos IgM anti-VHA durante el período octubre 2005-marzo 2006 fueron evaluados en este estudio. Los datos clínicos más frecuentes fueron presunción de hepatitis e ictericia (27,5 y 12,7%. La determinación de IgM anti-VHA se realizó por ensayo inmunoenzimático de micropartículas (MEIA; la de enzimas hepáticas en un multianalizador. De los 158 pacientes estudiados, 84 tenían valores elevados de AST/ALT; dentro de este grupo, el 82% fue reactivo para IgM anti-VHA. Los 74 pacientes restantes mostraron niveles normales de AST/ALT y solo 7 de ellos, bajo control de evolución por VHA ya confirmada, fueron reactivos para IgM anti-VHA. El 49% de los pacientes IgM anti-VHA reactivos correspondió a menores de 10 años. De acuerdo con estas observaciones, sugerimos que los estudios de laboratorio para confirmar infección aguda por VHA deberían realizarse en forma secuencial, ya que es innecesaria la determinación de anticuerpos IgM anti-VHA cuando las aminotransferasas séricas son normales.

No sólo hablamos de un replanteamiento y adaptación a las nuevas tecnologías, sino una “nueva forma” de pensar las marcas y su repercusión e imagen en la mente de los consumidores. Tal es el caso de las aplicaciones para los smartphones, que se han desarrollado con una virulencia impresionante, aproximadamente 200.000 actualmente, y el número continúa creciendo. Este estudio pretende ser una primera aproximación a la aparición de las marcas en las aplicaciones para móviles, específicamente en las aplicaciones destinadas a iPhone.Gracias esta investigación sabemos que es indispensable tener en cuenta tres criterios básicos en el desarrollo de aplicaciones; el primero y más importante es que los anunciantes deben centrarse en el análisis de las necesidades de los usuarios, determinar sus objetivos, elaborar planes de integración y sobre todo preparar los medios de comunicación multicanal y de apoyo a la comercialización. Si la aplicación es correcta pero no funciona adecuadamente, deteriora la imagen de la marca de cara al cliente. En segundo lugar, la experiencia del usuario en las aplicaciones móviles debe ser complementaria y coherente con su experiencia a través de otros canales, es decir, debe mantenerse fiel a la marca y a la identidad de la empresa. Y el tercer criterio, es importante para la marca ir adaptándose a las nuevas tecnologías, pues una incorporación precaria y mal desarrollada puede ser más perjudicial que no el

Cuando surgen nuevos o viejos problemas que no podemos resolver con las respuestas conocidas, se pone de manifiesto la necesidad de pensar de una manera distinta, de reinventar, de redefinir, de crear soluciones novedosas y originales. La creatividad es una capacidad universal e innata, que todos poseemos en diferentes grados y es una cualidad necesaria en el desarrollo de cualquier actividad artística o científica. Sin embargo, ha sido muy poco estudiada desde la Enfermería a pesar de que hablar de pensamiento creativo es hablar del mundo de las ideas, de progreso y de futuro. El objetivo de este trabajo es reflexionar sobre la importancia del estilo de pensamiento en la creatividad y la necesidad de estimularla y potenciarla desde los diferentes entornos enfermeros. Dado que la creatividad se puede aprender, para aumentar las aportaciones creativas en el colectivo enfermero es necesario desarrollar el pensamiento creativo individual desde el entorno educativo e institucional.The creative process is a method of solution of problems.

    Marisa R. Ferreira

    2015-03-01

    Full Text Available Given the significant impact that cultural events may have in local communities and their inherent organization complexity, it is important to understand their specificities. Most of the times cultural events disregard marketing and often marketing is distant from art. Thus an analysis of an internal marketing perspective might bring significant returns to the organization of such an event. This paper considers the three editions (2011, 2012 and 2013 of a cultural event – Noc Noc – organized by a local association in the city of Guimarães, Portugal. Its format is based in analogous events, as Noc Noc intends to convert everyday spaces (homes, commercial outlets and a number of other buildings into cultural spaces, organized and transformed by artists, hosts and audiences. By interviewing a sample of people (20 who have hosted this cultural event, sometimes doubling as artists, and by experiencing the three editions of the event, this paper analyses how the internal stakeholders understand this particular cultural event, analyzing specifically their motivations, ways of acting and participating, as well as their relationship with the public, with the organization of the event and with art in general. Results support that the motivations of artists and hosts must be identified in a timely and appropriate moment, as well as their views of this particular cultural event, in order to keep them participating, since low budget cultural events such as this one may have a key role in small cities.

We discuss if such a genetic transference could help to explain the cognitive profile of the formers, and particularly, if it could be used, along with other diverse lines of evidence (paleoanthropological and archaeological, to infer the possession of modern language by this species. Nevertheless, both the genetic data and the complementary evidences are suggestive of complex language plausibly being a human innovation. All the same, this possibility is still compatible with the evolutionary continuity of the diverse biological and cognitive devices that contribute to language processing and ultimately, with the possibility of Neanderthals being endowed with some kind of (less computationally complex language.

    La reciente constatación de ADN neandertal en determinadas poblaciones humanas modernas sugiere un cruce limitado entre ambas especies. Esta transferencia genética pudo haber afectado a las capacidades cognitivas de los neandertales y justificar, en particular, que hubiesen tenido lenguaje moderno. Tal posibilidad se examina a la luz de las propias evidencias genéticas, pero también de las de tipo paleoantropológico y arqueológico utilizadas habitualmente para tratar de inferir la presencia de lenguaje en otras especies de homínidos. En conjunto, dichas evidencias parecen sugerir que el lenguaje complejo habría sido una adquisición exclusiva de los humanos modernos. Ello es compatible, no obstante, con una continuidad evolutiva de los diversos mecanismos biológicos y cognitivos implicados en el procesamiento lingüistico y en último término, con la presencia de algún tipo de lenguaje, computacionalmente más simple, en los neandertales.

    2012-10-01

    Full Text Available This paper describes the application of an evolutionary algorithm, Restart Covariance Matrix Adaptation Evolution Strategy (RCMA-ES to the Generation Expansion Planning (GEP problem. RCMA-ES is a class of continuous Evolutionary Algorithm (EA derived from the concept of self-adaptation in evolution strategies, which adapts the covariance matrix of a multivariate normal search distribution. The original GEP problem is modified by incorporating Virtual Mapping Procedure (VMP. The GEP problem of a synthetic test systems for 6-year, 14-year and 24-year planning horizons having five types of candidate units is considered. Two different constraint-handling methods are incorporated and impact of each method has been compared. In addition, comparison and validation has also made with dynamic programming method.

    Como es bien sabido la expresión “historia”, en español y en otros lenguajes, contiene la ambigüedad de referirse tanto al objeto como a su conocimiento; así, por “historia” puede entenderse tanto el pasado humano como la disciplina científica que lo toma por objeto. La historia en este segundo sentido es la indagación metódica y sistemática de los fenómenos humanos del pasado.

    Full Text Available Podemos pensar que un quirófano es el Sancta Sanctorum de un Hospital, el sitio más "seguro" dentro del entorno más controlado, en todos los aspectos. Pero, es un hecho contrastado, aunque no siempre difundido, que los incendios en quirófano existen y suelen ser por causas internas al propio quirófano. Durante una intervención quirúrgica tenemos una posibilidad de sufrir un incendio en el momento más peligroso de la vida de un paciente y crear una situación de emergencia en un área crítica. Los objetivos de esta investigación son: - Incidir en la posibilidad de tener un incendio en quirófano. - Analizar las posibilidades del riesgo. - Detectar conductas y elementos peligrosos. - Analizar las medidas preventivas a adoptar.

    Full Text Available En las últimas décadas ha nacido una nueva idea de solidaridad. Con el "triunfo" de la democracia liberal, se ha creído que Occidente es el"mejor de los mundos posibles”. Consecuentemente, ha tomado forma la convicción, casi como obligación moral, de ayudar a los menos afortunados que viven fuera del sistema "perfecto" occidental. Sin embargo, debido principalmente a la reciente crisis económica, las ONG, históricamente consideradas el vehículo para enviar ayudas humanitarias, han empezado a actuar como empresas destinando gran parte de los fondos al marketing, haciendo pactos con las propias multinacionales y recortando dinero para los más necesitados: ¿Es esto ético y consecuente con las intenciones filantrópicas que deberían ser las propias del humanitarismo?

    2003-01-01

    The present study was designed to provide information about (i) the profile of carotene pigments and (ii) trace quantities of lycopene and β-carotene left in tomato purées. The ultrasensitive method comprising HPLC and thermal lens spectrometric (TLS) detection enabled us to detect as low as 0.3 and 1.1 ng ml-1 lycopene and β-carotene in purée extracts, respectively. Total concentration of β-carotene and lycopene (varying from 3 to 170 ng g-1) in the examined tomato purées may serve as an indicator of the carotene-specific antioxidative capacity of these products. Although conventional spectrophotometry can be used to rapidly assess the quality of products derived from tomatoes, a highly sensitive and selective method such as HPLC-TLS is needed for reliable analyses of samples such as, for example, those subjected to inappropriate storage and/or handling.

    Known examples of male to female sex reversal in mice are caused by either strain incompatibilities or mutations in genes required for male sex determination. The resultant XY females are often sterile or exhibit very poor fertility. We describe here embryonic stem (ES) cell growth conditions that promote the production of healthy, anatomically normal fertile and fecund female F0 generation mice completely derived from gene-targeted XY male ES cells. The sex reversal is a transient trait that is not transmitted to the F1 progeny. Growth media with low osmolality and reduced sodium bicarbonate, maintained throughout the gene targeting process, enhance the yield of XY females. As a practical application of the induced sex reversal, we demonstrate the generation of homozygous mutant mice ready for phenotypic studies by the breeding of F0 XY females with their isogenic XY male clonal siblings, thereby eliminating one generation of breeding and the associated costs.

Este texto afronta la plausibilidad de asumir la pregunta “¿Qué es el arte?” como problema filosófico. Para responder a este cuestionamiento acudimos a Wittgenstein, con el fin de realizarle una terapia filosófica a la pregunta misma y así mostrar que los principales paradigmas filosóficos sobre este asunto no son sino la manifestación de una confusión del lenguaje en torno al término ‘arte’.

    The progress behavior of evolution strategies (ES) using recombination is analyzed in this paper on the parabolic ridge. This test function represents landscapes far from the optimum. The ES algorithms with intermediate and dominant recombination are considered in the analysis. The derivations are presented for intermediate recombination. Thereafter, the formulae for dominant recombination are obtained using the so-called surrogate mutation model. In the analysis, the formulae are derived for the progress rate psi and for the stationary distance R(infinity) to the ridge axis. As a result, it will be shown that the progress rate psi can increase if recombination is applied. Simulations are used to show the appropriateness of the formulae derived.

    The progress rate of the (1,+ lambda)-ES (Evolution Strategy) is analyzed on the parabolic ridge test function. A different progress behavior is observed for the (1, lambda)-ES than for the sphere model test function. The characteristics of the progress rate picture for the plus strategy differs little from the one obtained for the sphere model, but this strategy has drastically worse progress rate values than those obtained for the comma strategy. The dynamics of the distance to the progress axis is also investigated. A theoretical formula is derived to estimate the change in this distance over generations. This formula is used to derive the expected value of the problem-specific distance to the ridge axis. The correctness of the formulae is supported by simulation results.

  5. Cloning mice and ES cells by nuclear transfer from somatic stem cells and fully differentiated cells.

    2011-01-01

    Cloning animals by nuclear transfer (NT) has been successful in several mammalian species. In addition to cloning live animals (reproductive cloning), this technique has also been used in several species to establish cloned embryonic stem (ntES) cell lines from somatic cells. It is the latter application of this technique that has been heralded as being the potential means to produce isogenic embryonic stem cells from patients for cell therapy (therapeutic cloning). These two types of cloning differ only in the steps after cloned embryos are produced: for reproductive cloning the cloned embryos are transferred to surrogate mothers to allow them to develop to full term and for therapeutic cloning the cloned embryos are used to derive ntES cells. In this chapter, a detailed NT protocol in mouse by using somatic stem cells (neuron and skin stem cells) and fully differentiated somatic cells (cumulus cells and fibroblast cells) as nuclear donors is described.

On montre qu’indépendamment de la législation en vigueur, les stratégies mises en œuvre par les États sont très différentes et que cela influe de façon déterminante sur les positionnements et revendications de la société civile vis-à-vis de ces données. Au cours de la dernière décennie, le Brésil tend vers une ouverture croissante de l’accès aux données concernant la déforestation, poussé à la transparence par la contre-expertise d’ONG nationales et par la pression internationale. En Guyane, on constate au contraire un mouvement de fermeture des données concernant le suivi des impacts de l’orpaillage, lié à une implication croissante des services d’État en charge de la sécurité nationale dans le processus de suivi.

    2010-01-01

    We present here the results of our observations of TrES-2 using the Infrared Array Camera on Spitzer. We monitored this transiting system during two secondary eclipses, when the planetary emission is blocked by the star. The resulting decrease in flux is 0.127% +/- 0.021%, 0.230% +/- 0.024%, 0.199% +/- 0.054%, and 0.359% +/- 0.060% at 3.6 microns, 4.5 microns, 5.8 microns, and 8.0 microns, respectively. We show that three of these flux contrasts are well fit by a blackbody spectrum with T(sub eff) = 1500 K, as well as by a more detailed model spectrum of a planetary atmosphere. The observed planet-to-star flux ratios in all four lRAC channels can be explained by models with and without a thermal inversion in the atmosphere of TrES-2, although with different atmospheric chemistry. Based on the assumption of thermochemical equilibrium, the chemical composition of the inversion model seems more plausible, making it a more favorable scenario. TrES-2 also falls in the category of highly irradiated planets which have been theoretically predicted to exhibit thermal inversions. However, more observations at infrared and visible wavelengths would be needed to confirm a thermal inversion in this system. Furthermore, we find that the times of the secondary eclipses are consistent with previously published times of transit and the expectation from a circular orbit. This implies that TrES-2 most likely has a circular orbit, and thus does not obtain additional thermal energy from tidal dissipation of a non-zero orbital eccentricity, a proposed explanation for the large radius of this planet. Key words: eclipses - infrared: stars - planetary systems - stars: individual (OSC 03549-02811) - techniques: photometric

    We have observed the Virgo Cluster spiral galaxy, NGC 4845, at 1.6 and 6 GHz using the Karl G. Jansky Very Large Array, as part of the Continuum Halos in Nearby Galaxies—an EVLA Survey (CHANG-ES). The source consists of a bright unresolved core with a surrounding weak central disk (1.8 kpc diameter). The core is variable over the 6 month timescale of the CHANG-ES data and has increased by a factor of ≈6 since 1995. The wide bandwidths of CHANG-ES have allowed us to determine the spectral evolution of this core, which peaks between 1.6 and 6 GHz (it is a Gigahertz-peaked spectrum source). We show that the spectral turnover is dominated by synchrotron self-absorption and that the spectral evolution can be explained by adiabatic expansion (outflow), likely in the form of a jet or cone. The CHANG-ES observations serendipitously overlap in time with the hard X-ray light curve obtained by Nikolajuk & Walter (2013), which they interpret as due to a tidal disruption event (TDE) of a super-Jupiter mass object around a 105 M⊙ black hole. We outline a standard jet model, provide an explanation for the observed circular polarization, and quantitatively suggest a link between the peak radio and peak X-ray emission via inverse Compton upscattering of the photons emitted by the relativistic electrons. We predict that it should be possible to resolve a young radio jet via VLBI as a result of this nearby TDE.
