Presencia de anti-SLA en una población en tratamiento con estatinas

Hipòtesis: la presencia d’auto anticossos contra selenoproteïnes (anti-SLA) podria afavorir la lesió muscular en pacients en tractament amb estatines. S’han avaluat 26 pacients sense tractament previ amb estatines, realitzant-se una analítica bassal, als 3 i als 6 mesos. No s’han observat anticossos anti-SLA en cap, augment estadísticament significatiu del títol d’ANAs als 3 (test de Wilcoxon, p=1.00) ni las 6 mesos (prova de Friedman, p=0.657), augment estadísticament significatiu dels nivells de CK als 3 (test de “t”, p=0.285) ni als 6 mesos (test de “t”, p=0.298), ni símptomes de miopatia al llarg del seguiment.

Los anticuerpos antinucleares en la artritis reumatoide: ¿factores predictores de ineficacia del tratamiento con anti-TNF?

L’objectiu de la recerca va ésser determinar si la preència de anticossos antinuclears (ANA) en els pacients amb artritis reumatoide (AR), condicionava una pitjor desposta al tractament amb anti-TNFα. Es va dissenyar un estudi observacional (cohorte retrospectiva) de 66 paciente que es disposaven a iniciar tractament amb anti-TNFα., i dels que es disposava d’una determinación basal de ANA. Es disposava en tots ells un index DAS-28 als 0, 3 i 6 mesos, amb el que es va avaluar la desposta segons els criteris EULAR: No s’observaren diferencies estaísticament significatives entre els pacients ANA-negatius i ANA-positius als 3 mesos de tractament. S’observà una tendència als 6 mesos de tractament entre els ANA-negatius a presentar millor resposta respecte als ANA-positius, sense poder establir-se diferències estadísticamente significatives

Plane-to-plane positioning from image-based visual servoing and structured light

In this paper we face the problem of positioning a camera attached to the end-effector of a robotic manipulator so that it gets parallel to a planar object. Such problem has been treated for a long time in visual servoing. Our approach is based on linking to the camera several laser pointers so that its configuration is aimed to produce a suitable set of visual features. The aim of using structured light is not only for easing the image processing and to allow low-textured objects to be treated, but also for producing a control scheme with nice properties like decoupling, stability, well conditioning and good camera trajectory

Adding new components to the knowledge plane GMPLS over WDM networks

A recent study defines a new network plane: the knowledge plane. The incorporation of the knowledge plane over the network allows having more accurate information of the current and future network states. In this paper, the introduction and management of the network reliability information in the knowledge plane is proposed in order to improve the quality of service with protection routing algorithms in GMPLS over WDM networks. Different experiments prove the efficiency and scalability of the proposed scheme in terms of the percentage of resources used to protect the network

Continguts sobre anti vacunació dintre les webs de parla espanyola i catalana

Tant a Nordamericà com a Australia el moviment Antivacunació està creixent i cada cop hi ha més nens que no es vacunen. Es preveu que aquí a Espanya el moviment antivacunes anirà en augment. Els continguts de les webs antivacunes influeixen en les decisions dels pares quan volen vacunar els infants.

Clustering algorithms for anti-money laundering using graph theory and social network analysis

HEMOLIA (a project under European community’s 7th framework programme) is a new generation Anti-Money Laundering (AML) intelligent multi-agent alert and investigation system which in addition to the traditional financial data makes extensive use of modern society’s huge telecom data source, thereby opening up a new dimension of capabilities to all Money Laundering fighters (FIUs, LEAs) and Financial Institutes (Banks, Insurance Companies, etc.). This Master-Thesis project is done at AIA, one of the partners for the HEMOLIA project in Barcelona. The objective of this thesis is to find the clusters in a network drawn by using the financial data. An extensive literature survey has been carried out and several standard algorithms related to networks have been studied and implemented. The clustering problem is a NP-hard problem and several algorithms like K-Means and Hierarchical clustering are being implemented for studying several problems relating to sociology, evolution, anthropology etc. However, these algorithms have certain drawbacks which make them very difficult to implement. The thesis suggests (a) a possible improvement to the K-Means algorithm, (b) a novel approach to the clustering problem using the Genetic Algorithms and (c) a new algorithm for finding the cluster of a node using the Genetic Algorithm.

Anti-aging : Una relectura contemporània de Dorian Gray

Human synthetic lethal inference as potential anti-cancer target gene detection

Background: Two genes are called synthetic lethal (SL) if mutation of either alone is not lethal, but mutation of both leads to death or a significant decrease in organism's fitness. The detection of SL gene pairs constitutes a promising alternative for anti-cancer therapy. As cancer cells exhibit a large number of mutations, the identification of these mutated genes' SL partners may provide specific anti-cancer drug candidates, with minor perturbations to the healthy cells. Since existent SL data is mainly restricted to yeast screenings, the road towards human SL candidates is limited to inference methods. Results: In the present work, we use phylogenetic analysis and database manipulation (BioGRID for interactions, Ensembl and NCBI for homology, Gene Ontology for GO attributes) in order to reconstruct the phylogenetically-inferred SL gene network for human. In addition, available data on cancer mutated genes (COSMIC and Cancer Gene Census databases) as well as on existent approved drugs (DrugBank database) supports our selection of cancer-therapy candidates.Conclusions: Our work provides a complementary alternative to the current methods for drug discovering and gene target identification in anti-cancer research. Novel SL screening analysis and the use of highly curated databases would contribute to improve the results of this methodology.

Anàlisi del títol d’anticossos anti-achr i la seva correlació clínica en pacients amb miastenia gravis seropositiva

Els anticossos contra el receptor de l’acetilcolina representen el principal mecanisme patogènic en la Miastènia Gravis, però la seva utilitat com a biomarcador durant el seguiment de la malaltia és desconeguda. S’ha realitzat un estudi retrospectiu amb 77 pacients que disposen de múltiples determinacions en el títol d’anticossos, relacionant-los amb l’estat clínic de cada moment. L’anàlisi demostra una correlació significativa entre la variació dels Ac i l’evolució clínica intrapacient, tant al llarg de la malaltia com en les fluctuacions clíniques. Per tant, la determinació seriada d’anticossos representa una mida dels canvis clínics i pot ser d’utilitat en el seguiment d’aquests pacients.

La Representación del movimiento social anti-desahucios en la prensa española : una perspectva de agenda-setting

Aunque hasta este momento se abundan estudios acerca de los movimientos sociales, la mayoría se aborda desde los propios movimientos y investigar los movimientos que se desarrollan y alcanzan una magnitud increíble mediante las redes sociales ocupa una posición imprescindible en este tipo de la investigación, mientras que realizar un estudio sobre los movimientos sociales a través de los medios tradicionales y oficiales carece de atención de los investigadores. Por esta razón, tomo el caso del movimiento antidesahucios como un ejemplo clàsico para examinar los movimientos sociales desde la perspectiva mediàtica, es decir, la perspectiva de agenda-setting

(Re-) Shaping hatred: Anti-Semitic attitudes in Germany, 1890-2006

In this paper, we assess the determinants of long-run persistence of localculture, and examine the success of policy interventions designed to change attitudes.We analyze anti-Semitic attitudes drawing on individual-level survey results fromGermany s social value survey in 1996 and 2006. On average, we find that historicalvoting patterns for anti-Semitic parties between 1890 and 1933 are powerfulpredictors of anti-Jewish attitudes today. There is evidence that transmission takesplace both vertically (parent to child) and horizontally (among peers). Policy modifiedGerman views on Jews in important ways: The cohort that grew up under the Naziregime shows significantly higher levels of anti-Semitism. After 1945, the victoriousAllies implemented denazification programs in their zones of occupation. We usedifferences in these policies between the occupying powers as a source of identifyingvariation. The US and French zones today still show high anti-Semitism, reflecting anambitious botched attempt at denazification. In contrast, the British and Soviet zones,register much lower levels of Jew-hatred.

Persecution perpetuated: The medieval origins of anti-semitic violence in Nazi Germany

How persistent are cultural traits? This paper uses data on anti-Semitism in Germany and finds continuity at the local level over more than half a millennium. When the Black Death hit Europe in 1348-50, killing between one third and one half of the population, its cause was unknown. Many contemporaries blamed the Jews. Cities all over Germany witnessed mass killings of their Jewish population. At the same time, numerous Jewish communities were spared these horrors. We use plague pogroms as an indicator for medieval anti-Semitism. Pogroms during the Black Death are a strong and robust predictor of violence against Jews in the 1920s, and of votes for the Nazi Party. In addition, cities that saw medieval anti-Semitic violence also had higher deportation rates for Jews after 1933, were more likely to see synagogues damaged or destroyed in the Night of Broken Glass in 1938, and their inhabitants wrote more anti-Jewish letters to the editor of the Nazi newspaper Der Stürmer.

A Variant of Higher-Order Anti-Unification

We present a rule-based Huet’s style anti-unification algorithm for simply-typed lambda-terms in ɳ long β normal form, which computes a least general higher-order pattern generalization. For a pair of arbitrary terms of the same type, such a generalization always exists and is unique modulo α equivalence and variable renaming. The algorithm computes it in cubic time within linear space. It has been implemented and the code is freely available
