Trichuris trichiura in a post-Colonial Brazilian mummy

Trichuris trichiura is a soil-transmitted helminth which is prevalent in warm, moist, tropical and subtropical regions of the world with poor sanitation. Heavy whipworm can result either in Trichuris dysenteric syndrome - especially in children - or in a chronic colitis. In heavy infections, worms can spread proximally and may cause ileitis. Here we provide first microscopic evidence for a T. trichiura adult worm embedded in the rectum of a post-Colonial Brazilian adult mummy. During Colonial and post-Colonial times, many European chroniclers described a parasitic disease named Maculo whose symptomatology coincides with heavy helminthiasis. Based on our findings and on comparison of ancient textual evidence with modern description of heavy whipworm, we feel confident in considering that the two syndromes are expressions of the same pathological condition.

Mutation prevalence of cerebral cavernous malformation genes in Spanish patients.

OBJECTIVE To study the molecular genetic and clinical features of cerebral cavernous malformations (CCM) in a cohort of Spanish patients. METHODS We analyzed the CCM1, CCM2, and CCM3 genes by MLPA and direct sequencing of exons and intronic boundaries in 94 familial forms and 41 sporadic cases of CCM patients of Spanish extraction. When available, RNA studies were performed seeking for alternative or cryptic splicing. RESULTS A total of 26 pathogenic mutations, 22 of which predict truncated proteins, were identified in 29 familial forms and in three sporadic cases. The repertoire includes six novel non-sense and frameshift mutations in CCM1 and CCM3. We also found four missense mutations, one of them located at the third NPXY motif of CCM1 and another one that leads to cryptic splicing of CCM1 exon 6. We found four genomic deletions with the loss of the whole CCM2 gene in one patient and a partial loss of CCM1and CCM2 genes in three other patients. Four families had mutations in CCM3. The results include a high frequency of intronic variants, although most of them localize out of consensus splicing sequences. The main symptoms associated to clinical debut consisted of cerebral haemorrhage, migraines and epileptic seizures. The rare co-occurrence of CCM with Noonan and Chiari syndromes and delayed menarche is reported. CONCLUSIONS Analysis of CCM genes by sequencing and MLPA has detected mutations in almost 35% of a Spanish cohort (36% of familial cases and 10% of sporadic patients). The results include 13 new mutations of CCM genes and the main clinical symptoms that deserves consideration in molecular diagnosis and genetic counselling of cerebral cavernous malformations.

Analysis of genes encoding penicillin-binding proteins in clinical isolates of Acinetobacter baumannii.

There is limited information on the role of penicillin-binding proteins (PBPs) in the resistance of Acinetobacter baumannii to β-lactams. This study presents an analysis of the allelic variations of PBP genes in A. baumannii isolates. Twenty-six A. baumannii clinical isolates (susceptible or resistant to carbapenems) from three teaching hospitals in Spain were included. The antimicrobial susceptibility profile, clonal pattern, and genomic species identification were also evaluated. Based on the six complete genomes of A. baumannii, the PBP genes were identified, and primers were designed for each gene. The nucleotide sequences of the genes identified that encode PBPs and the corresponding amino acid sequences were compared with those of ATCC 17978. Seven PBP genes and one monofunctional transglycosylase (MGT) gene were identified in the six genomes, encoding (i) four high-molecular-mass proteins (two of class A, PBP1a [ponA] and PBP1b [mrcB], and two of class B, PBP2 [pbpA or mrdA] and PBP3 [ftsI]), (ii) three low-molecular-mass proteins (two of type 5, PBP5/6 [dacC] and PBP6b [dacD], and one of type 7 (PBP7/8 [pbpG]), and (iii) a monofunctional enzyme (MtgA [mtgA]). Hot spot mutation regions were observed, although most of the allelic changes found translated into silent mutations. The amino acid consensus sequences corresponding to the PBP genes in the genomes and the clinical isolates were highly conserved. The changes found in amino acid sequences were associated with concrete clonal patterns but were not directly related to susceptibility or resistance to β-lactams. An insertion sequence disrupting the gene encoding PBP6b was identified in an endemic carbapenem-resistant clone in one of the participant hospitals.

Epigenetic mechanisms in non-alcoholic fatty liver disease: An emerging field.

Non-alcoholic fatty liver disease (NAFLD) is an emerging health concern in both developed and non-developed world, encompassing from simple steatosis to non-alcoholic steatohepatitis (NASH), cirrhosis and liver cancer. Incidence and prevalence of this disease are increasing due to the socioeconomic transition and change to harmful diet. Currently, gold standard method in NAFLD diagnosis is liver biopsy, despite complications and lack of accuracy due to sampling error. Further, pathogenesis of NAFLD is not fully understood, but is well-known that obesity, diabetes and metabolic derangements played a major role in disease development and progression. Besides, gut microbioma and host genetic and epigenetic background could explain considerable interindividual variability. Knowledge that epigenetics, heritable events not caused by changes in DNA sequence, contribute to development of diseases has been a revolution in the last few years. Recently, evidences are accumulating revealing the important role of epigenetics in NAFLD pathogenesis and in NASH genesis. Histone modifications, changes in DNA methylation and aberrant profiles or microRNAs could boost development of NAFLD and transition into clinical relevant status. PNPLA3 genotype GG has been associated with a more progressive disease and epigenetics could modulate this effect. The impact of epigenetic on NAFLD progression could deserve further applications on therapeutic targets together with future non-invasive methods useful for the diagnosis and staging of NAFLD.

Théorie de l'argumentation et théorie du texte : quelques enjeux d'une approche textuelle de l'argumentation

Résumé : La question du texte, négligée par la plupart des théories de l'argumentation, est ici abordée frontalement. L'étude est exemplifiée par le cas d'un genre journalistique de l'argumentation : une tribune libre écrite par un astro-physicien qui pose un certain nombre de problèmes intéressants. D'un point de vue méthodologique, la distinction de trois niveaux d'analyse est conforme aux grandes options de la linguistique textuelle : niveaux périodique micro-textuel de l'argumentation, niveau méso-textuel des « cellules argumentatives » et niveau macro-textuel du plan de texte. Ce dernier niveau ouvre sur la généricité complexe d'un texte qui relève à la fois d'un genre de l'opinion journalistique et du genre de la controverse polémique entre scientifiques à propos du traitement médiatique prématuré d'une découverte scientifique.

Una aproximación al dequeísmo desde la perspectiva diacrónica

El dequeísmo es una variación marcada del sistema gramatical del español, consistente en la anteposición y adición de la preposición de ante la conjunción subordinante que, sin que su presencia sea exigida por ningún elemento oracional. Asimismo, el dequeísmo suele aflorar con mayor frecuencia en la comunicación oral y coloquial y, por ello, acostumbra a asociarse a un registro informal e, incluso, vulgar, por lo que la prescripción normativa recomienda evitar su uso en la lengua culta. No obstante, debido a su actual expansión entre la comunidad de hablantes hispanos se considera conveniente estudiar el origen y desarrollo de las construcciones dequeístas a lo largo de la historia del español, puesto que se trata de un fenómeno todavía sin un marco teórico único y específico. Mi tesina: “Una aproximación al dequeísmo desde una perspectiva diacrónica” se enfoca siguiendo la perspectiva diacrónica y concibe el dequeísmo como un cambio sintáctico inacabado e iniciado en el transcurso del español medieval al clásico a partir de la gramaticalización de la preposición de. Por otra parte, en este estudio se ofrece una explicación de carácter histórico, cuyo propósito es hacer comprender mejor la complejidad de esta construcción sintáctica. Para ello, se parte del análisis de una serie de estructuras formadas con los predicados verbales decir, pensar, creer y temer, seguidos de la secuencia de que + Oración subordinada de sustantivo, halladas en el Corpus Diacrónico del Español (CORDE). Tras una búsqueda exhaustiva de dichas construcciones puede concluirse que no se encuentran estructuras claramente dequeístas hasta el español clásico (siglo XVI). Además, esta investigación pone de manifiesto la importancia en el estudio del dequeísmo de la construcción tematizada de la pasiva refleja con el verbo decir. Por ejemplo: «Y lo que se dice de que allí son mejor criados, y doctrinados no me convence» (CORDE: 1648, Juan Solórzano y Pereira, Política indiana, España); en donde “lo que” funciona como tema de la subordinada sustantiva, la cual presenta una función discursiva remática. Estas estructuras no son dequeístas, pero podrían explicar el origen dequeísta de las pasivas reflejas con decir. En conclusión, esta investigación se ha concebido con el firme propósito de mostrar la realidad de este cambio sintáctico que está sucediendo en el español contemporáneo, pero sin olvidar que no ha surgido por azar, sino que debe ser un fenómeno analizado desde la sintaxis histórica y desde la gramaticalización de la preposición de, con el objetivo de poder describir y caracterizar el fenómeno desde sus orígenes hasta la actualidad

Representações sociais do HIV/AIDS entre adolescentes: implicações para os cuidados de enfermagem

Objetivando-se discutir as implicações das representações sociais do HIV/AIDS para as relações interpessoais e práticas de proteção entre adolescentes, foram realizadas 15 entrevistas semi-diretivas com adolescentes, portadares e não portadores do HIV, atendidos em um Hospital Escola do Rio de Janeiro. Para análise dos dados utilizou-se o software ALCESTE 4.5 que realiza uma análise hierárquica descendente de material textual. Observou-se que a representação social da aids estrutura-se em torno de cognições ligadas à prevenção, revelando uma contradição entre os conteúdos de conhecimento e as práticas relatadas pelo grupo. Sugere-se que as práticas de enfermagem devem ter como objetivo reduzir a distância entre práticas, representações e o conhecimento científico.

Discourse Type Clustering using POS n-gram Profiles and High-Dimensional Embeddings

Abstract: To cluster textual sequence types (discourse types/modes) in French texts, K-means algorithm with high-dimensional embeddings and fuzzy clustering algorithm were applied on clauses whose POS (part-ofspeech) n-gram profiles were previously extracted. Uni-, bi- and trigrams were used on four 19th century French short stories by Maupassant. For high-dimensional embeddings, power transformations on the chi-squared distances between clauses were explored. Preliminary results show that highdimensional embeddings improve the quality of clustering, contrasting the use of bi and trigrams whose performance is disappointing, possibly because of feature space sparsity.

Sistema de significados sobre a finalidade do trabalho na Saúde da Família: uma abordagem qualitativa

Trata-se de um estudo exploratório e descritivo, com abordagem qualitativa, objetivando compreender o sistema de significados sobre a finalidade do trabalho de enfermeiros e médicos das equipes da Saúde da Família, nas cidades de Rio Grande e Pelotas. A entrevista semidirigida, individual e gravada, foi utilizada na coleta dos dados, seguindo-se uma análise temática dos depoimentos de 82 participantes. O significado nuclear da finalidade, como fim transmutado em produto do trabalho coletivo, mostrou-se alinhado com a possibilidade de mudanças e aquisição de comportamentos individuais e coletivos saudáveis por parte da comunidade, evidenciando-se o componente da eticidade no processo, por meio de categorias como a solidariedade e a compaixão. Disso decorreu, na produção textual, um marcador da condição humana na construção da finalidade do trabalho. Por meio da análise e discussão crítica da temática, este estudo contribui para a dimensão macro da formação de competências e adequação às necessidades sociais de saúde.

Summarization of specialized discourse: the case of medical articles in Spanish

In this article, we present the current state of our work on a linguistically-motivated model for automatic summarization of medical articles in Spanish. The model takes into account the results of an empirical study which reveals that, on the one hand, domain-specific summarization criteria can often be derived from the summaries of domain specialists, and, on the other hand, adequate summarization strategies must be multidimensional, i.e., cover various types of linguistic clues. We take into account the textual, lexical, discursive, syntactic and communicative dimensions. This is novel in the field of summarization. The experiments carried out so far indicate that our model is suitable to provide high quality summarizations.

Mining and exploiting domain-specific corpora in the PANACEA platform

The objective of the PANACEA ICT-2007.2.2 EU project is to build a platform that automates the stages involved in the acquisition,production, updating and maintenance of the large language resources required by, among others, MT systems. The development of a Corpus Acquisition Component (CAC) for extracting monolingual and bilingual data from the web is one of the most innovative building blocks of PANACEA. The CAC, which is the first stage in the PANACEA pipeline for building Language Resources, adopts an efficient and distributed methodology to crawl for web documents with rich textual content in specific languages and predefined domains. The CAC includes modules that can acquire parallel data from sites with in-domain content available in more than one language. In order to extrinsically evaluate the CAC methodology, we have conducted several experiments that used crawled parallel corpora for the identification and extraction of parallel sentences using sentence alignment. The corpora were then successfully used for domain adaptation of Machine Translation Systems.

Early Christian School Texts on Papyri: the database

Database of papyrus school texts which may be identified as Christian on the basis of the presence of some internal indicator: Christian symbols, textual content originating from the Bible or of a clearly Christian origin proposed as a copying exercise, or Christian contents not part of the exercise itself, such as prayers or invocations.

Excuse me, but your accent is very unusual. The complexity of establishing third languages in Inglourious Basterds. Applying a model of translation analysis to dubbing

The growing multilingual trend in movie production comes with a challenge for dubbing translators since they are increasingly confronted with more than one source language. The main purpose of this master’s thesis is to provide a case study on how these third languages (see CORRIUS and ZABALBEASCOA 2011) are rendered. Another aim is to put a particular focus on their textual and narrative functions and detect possible shifts that might occur in translations. By applying a theoretical model for translation analysis (CORRIUS and ZABALBEASCOA 2011), this study describes how third languages are rendered in the German, Spanish, and Italian dubbed versions of the 2009 Tarantino movie Inglourious Basterds. A broad range of solution-types are thereby revealed and prevalent restrictions of the translation process identified. The target texts are brought in context with some sociohistorical aspects of dubbing in order to detect prevalent norms of the respective cultures andto discuss the acceptability of translations (TOURY 1995). The translatability potential of even highly complex multilingual audiovisual texts is demonstrated in this study. Moreover, proposals for further studies in multilingual audiovisual translation are outlined and the potential for future investigations in this field thereby emphasised.
